ADVISERS MANAGEMENT TRUST
 
- -------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios:  Balanced Portfolio, Government  Income Portfolio, Growth Portfolio,
International Portfolio, Limited Maturity Bond Portfolio, Liquid Asset Portfolio
and  Partners  Portfolio.   While  each  portfolio   (each  a  "Portfolio"   and
collectively,  "Portfolios")  issues  its own  class  of shares,  which  in some
instances have rights separate  from other classes of  shares, the Trust is  one
entity with respect to certain important items (e.g., certain voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of the Balanced Portfolio
are also offered directly to qualified pension and retirement plans  ("Qualified
Plans").
 
- --------------------------------------------------------------------------------
 
   
   EACH  PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS CORRESPONDING
SERIES (EACH  A "SERIES")  OF  ADVISERS MANAGERS  TRUST ("MANAGERS  TRUST"),  AN
OPEN-END MANAGEMENT INVESTMENT COMPANY. ALL SERIES OF MANAGERS TRUST ARE MANAGED
BY  NEUBERGER&BERMAN  MANAGEMENT  INCORPORATED ("N&B  MANAGEMENT").  EACH SERIES
INVESTS IN SECURITIES IN ACCORDANCE WITH AN INVESTMENT OBJECTIVE, POLICIES,  AND
LIMITATIONS  IDENTICAL TO THOSE  OF ITS CORRESPONDING  PORTFOLIO. THE INVESTMENT
PERFORMANCE OF  EACH  PORTFOLIO WILL  DIRECTLY  CORRESPOND WITH  THE  INVESTMENT
PERFORMANCE  OF ITS CORRESPONDING SERIES. THIS "MASTER/FEEDER FUND" STRUCTURE IS
DIFFERENT FROM THAT OF  MANY OTHER INVESTMENT  COMPANIES WHICH DIRECTLY  ACQUIRE
AND  MANAGE THEIR  OWN PORTFOLIOS  OF SECURITIES.  FOR MORE  INFORMATION ON THIS
UNIQUE STRUCTURE THAT  YOU SHOULD CONSIDER,  SEE "SPECIAL INFORMATION  REGARDING
ORGANIZATION, CAPITALIZATION, AND OTHER MATTERS" ON PAGE 24.
    
   AN  INVESTMENT  IN THE  LIQUID ASSET  PORTFOLIO,  AS IN  ANY MUTUAL  FUND, IS
NEITHER INSURED NOR GUARANTEED BY THE U.S. GOVERNMENT. ALTHOUGH THE LIQUID ASSET
PORTFOLIO SEEKS TO MAINTAIN A  NET ASSET VALUE OF $1.00  PER SHARE, THERE IS  NO
ASSURANCE THAT IT WILL BE ABLE TO DO SO.
   
   Please  read this  Prospectus before investing  in any of  the Portfolios and
keep it  for future  reference. The  Prospectus contains  information about  the
Portfolios that a prospective investor should know before investing. A Statement
of Additional Information ("SAI") about the Portfolios and the Series, dated May
1,  1996, is  on file with  the Securities  and Exchange Commission.  The SAI is
incorporated herein by  reference (so it  is legally considered  a part of  this
Prospectus).  You can obtain a free copy of  the SAI by writing the Trust at 605
Third Avenue, 2nd Floor, New York, NY 10158-0180.
    
 
   MUTUAL FUND SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED BY,  ANY
BANK  OR OTHER DEPOSITORY INSTITUTION.  SHARES ARE NOT INSURED  BY THE FDIC, THE
FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY, AND ARE SUBJECT TO INVESTMENT  RISK,
INCLUDING THE POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED.
 
   THESE  SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE  SECURITIES COMMISSION, NOR HAS THE  SECURITIES
AND  EXCHANGE  COMMISSION OR  ANY STATE  SECURITIES  COMMISSION PASSED  UPON THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.
   The  purchaser  of  a  Variable  Contract  should  read  this  Prospectus  in
conjunction with the prospectus for his or her Variable Contract.

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and limitations  that are  identical to  those of  the Portfolio.  The
trustees  of  the Trust  believe that  this  "master/feeder fund"  structure may
benefit shareholders.  For  more  information  about  the  organization  of  the
Portfolios  and the Series, including certain features of the master/feeder fund
structure, see "Special Information Regarding Organization, Capitalization,  and
Other  Matters" on page 24. For more  details about each Series, its investments
and their risks, see "Investment Programs"  on page 15, "Ratings of  Securities"
on  page 19, "Borrowings" on  page 20, and "Description  of Investments" on page
35.
    
   Here is  a  summary  of  important  features  of  the  Portfolios  and  their
corresponding  Series. You may want to invest  in a variety of Portfolios to fit
your particular investment needs.  Of course, there can  be no assurance that  a
Portfolio will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   An  investment in  any Portfolio involves  certain risks,  depending upon the
types of  investments made  by its  corresponding Series.  Special risk  factors
apply  to  investments,  which  may  be  made  by  certain  Series,  in  foreign
securities,  options  and  futures  contracts,   zero  coupon  bonds  and   swap
agreements,  and debt securities rated below  investment grade. For those Series
investing in fixed income securities, the value of such securities is likely  to
decline  in times of rising interest rates and rise in times of falling interest
rates. In general, the longer the maturity of a fixed income security, the  more
pronounced  is the  effect of  a change in  interest rates  on the  value of the
security.
   AMT Government Income Investments invests at least 25% of its total assets in
mortgage-backed and  asset-backed securities,  may engage  in lending  portfolio
securities  and other  investment techniques, and  may borrow  for leverage. The
investment program of AMT Government  Income Investments is intended to  protect
principal  by  focusing on  the credit  quality of  the issuers.  Principal may,
however, be at risk due to market rate fluctuations.
   AMT Partners Investments may invest up to 15% of its net assets, measured  at
the  time of  investment, in  corporate debt  securities rated  below investment
grade or comparable  unrated securities. AMT  Limited Maturity Bond  Investments
may  invest up to 10% of its net  assets, measured at the time of investment, in
debt securities rated below investment  grade or comparable unrated  securities.
AMT  Balanced Investments may invest up to 10% of the debt securities portion of
its investments, measured at  the time of investment,  in debt securities  rated
below  investment grade or comparable unrated securities. Securities rated below
investment grade  as well  as  unrated securities  are  often considered  to  be
speculative and usually entail greater risk. For more information on lower-rated
securities,  see "Ratings  of Securities" in  this Prospectus  and "Fixed Income
Securities" in the SAI.
   
   AMT  International  Investments  seeks  long-term  capital  appreciation   by
investing  primarily in a diversified portfolio  of equity securities of issuers
organized and doing business  principally outside the U.S.  The strategy of  N&B
Management  is to select  attractive investment opportunities  outside the U.S.,
allocating  the  assets  among   economically  mature  countries  and   emerging
industrialized  countries. The Series will invest primarily in equity securities
of medium to large  capitalization companies traded  on foreign exchanges.  From
time  to time,  the Series  may invest  a significant  portion of  its assets in
Japan. Because the Portfolio, through  the Series, invests primarily in  foreign
securities,  it may be subject to greater  risks and higher expenses than equity
funds that invest  primarily in securities  of U.S. issuers.  Such risks may  be
even  greater in emerging industrialized and less developed countries. The risks
of investing in  foreign securities include,  but are not  limited to,  possible
adverse political and economic developments in a particular country, differences
between foreign and U.S. regulatory systems, and foreign securities markets that
are  smaller and less well regulated than those  in the U.S. There is often less
information publicly available about foreign issuers, and many foreign countries
do not follow the financial  accounting standards used in  the U.S. Most of  the
securities  held  by  the  Series  are  likely  to  be  denominated  in  foreign
currencies, and the  value of  these investments  can be  adversely affected  by
fluctuations in foreign currency values. Some foreign currencies can be volatile
and  may be subject to governmental controls or intervention. The Series may use
techniques such as options, futures, forward foreign currency exchange contracts
and short selling, for hedging and in  an attempt to realize income. The  Series
may  also use leverage to facilitate transactions entered into by the Series for
hedging purposes. The  use of  these strategies  may entail  special risks.  See
"Borrowings" and "Description of Investments" in this Prospectus.

          Management
 
- --------------------------------------------------------------------------------
 
   N&B  Management,  with  the assistance  of  Neuberger&Berman  as sub-adviser,
selects investments for all Series. N&B Management also provides  administrative
services  to the Series and the Portfolios and acts as distributor of the shares
of all Portfolios. See "Management and Administration" in this Prospectus.
 
          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   
   While each Series has its own investment objective, policies and limitations,
AMT Growth, Partners and Balanced Investments (equity portion) are each  managed
using one of two basic investment approaches -- value and growth.
    
   
   A value-oriented portfolio manager buys stocks that are selling for less than
their   perceived  market  value.  These   include  stocks  that  are  currently
under-researched or are temporarily out of favor on Wall Street.
    
   
   Portfolio managers identify  value stocks in  several ways. One  of the  most
common  identifiers is a low price-to-earnings  ratio -- that is, stocks selling
at multiples of earnings per share that are  lower than that of the market as  a
whole.  Other  criteria are  high  dividend yield,  a  strong balance  sheet and
financial position, a recent company restructuring with the potential to realize
hidden values, strong management, and low price-to-book value (net value of  the
company's assets).
    
   
   While  a value approach concentrates on undervalued securities in relation to
their fundamental  economic  value,  a  growth  approach  seeks  out  stocks  of
companies  that  are projected  to grow  at above-average  rates and  may appear
poised for a period of accelerated earnings.
    
   
   The growth portfolio manager is  willing to pay a  higher share price in  the
hope  that the stock's earnings momentum will carry the stock's price higher. As
a stock's price increases based on  strong earnings, the stock's original  price
appears  low in  relation to  the growth  rate of  its earnings.  Sometimes this
happens when a particular company or  industry is temporarily out of favor  with
the  market or under-researched. This strategy is called "growth at a reasonable
price."
    
   
   Neuberger&Berman believes that,  over time, securities  that are  undervalued
are  more likely  to appreciate in  price and be  subject to less  risk of price
decline than securities whose market prices have already reached their perceived
economic value.  This approach  also contemplates  selling portfolio  securities
when they are considered to have reached their potential.
    
   
   In  general, AMT  Growth and  Balanced Investments  (equity portion)  place a
greater emphasis on finding securities  whose measures of fundamental value  are
low  in relation to the  growth rate of their future  earnings and cash flow, as
projected by the portfolio  manager, and these Series  are therefore willing  to
invest in securities with prices that are somewhat higher multiples of earnings.
AMT  Partners Investments places greater emphasis on a value-oriented investment
approach.
    
   
   AMT International  Investments uses  an investment  process that  includes  a
combination  of country  selection and  individual security  selection primarily
based on a value-driven investment approach.
    
   
   While these approaches  have resulted in  solid returns over  the long  term,
there can be no assurance that these results will be achieved in the future. For
more information, see "Performance Information" in this Prospectus.

          Annual Portfolio Operating Expenses
          (AS PERCENTAGE OF AVERAGE DAILY NET ASSETS)
 
- --------------------------------------------------------------------------------
 
   The  following tables shows annual Total  Operating Expenses for the Balanced
Portfolio, which are paid out of the assets of the Balanced Portfolio and  which
include  the  Portfolio's pro  rata  portion of  the  Operating Expenses  of the
Balanced Series.  These  expenses are  borne  indirectly by  Balanced  Portfolio
shareholders.  The Balanced Portfolio pays  N&B Management an administration fee
based on the Portfolio's average daily net assets. The Balanced Series pays  N&B
Management  a management  fee based  on the  Balanced Series'  average daily net
assets; a pro  rata portion  of this  fee is  borne indirectly  by the  Balanced
Portfolio. Therefore, the table combines management and administration fees. The
Portfolio and Series also incur other expenses for things such as accounting and
legal   fees,  maintaining   shareholder  records   and  furnishing  shareholder
statements and Portfolio reports. "Operating Expenses" exclude interest,  taxes,
brokerage  commissions, and extraordinary expenses. The Portfolio's expenses are
factored into its  share prices and  dividends and are  not charged directly  to
Portfolio    shareholders.   For   more   information,   see   "Management   and
Administration" in this Prospectus and the SAI.

   Total  Operating  Expenses   for  the  Balanced   Portfolio  are   annualized
projections  based  upon  current  administration  fees  for  the  Portfolio and
management fees for  the Balanced  Series, with  "Other Expenses"  based on  the
Portfolio's  expenses for the  past fiscal year.  "Management and Administration
Fees" have been restated to reflect current expenses. The trustees of the  Trust
believe  that the aggregate per share expenses of the Balanced Portfolio and the
Balanced Series will be approximately equal to the expenses the Portfolio  would
incur  if its assets were invested directly in the type of securities being held
by  the  Balanced  Series.  The  trustees   of  the  Trust  also  believe   that
    
 
6
<PAGE>
   
investment  in  the Balanced  Series by  investors in  addition to  the Balanced
Portfolio may enable  the Balanced Series  to achieve economies  of scale  which
could reduce expenses. The expenses and, accordingly, the returns of other funds
that  may invest in the  Balanced Series, may differ  from those of the Balanced
Portfolio.
    
   To illustrate  the  effect  of  Operating Expenses,  let's  assume  that  the
Balanced  Portfolio's annual return is 5% and that it had annual Total Operating
Expenses described in  the table  above. For every  $1,000 you  invested in  the
Balanced  Portfolio, you would have paid the following amounts of total expenses
if you closed your account at the end of each of the following time periods:

   The assumption  in  this  example  of  a 5%  annual  return  is  required  by
regulations  of the Securities and Exchange  Commission applicable to all mutual
funds. The information in the table should not be considered a representation of
past or future expenses or  rates of return; actual  expenses or returns may  be
greater or less than those shown.

  NOTES:
   
1) The per share amounts which are shown have been computed based on the average
   number of shares outstanding during each year.
    
   
2) The per share amounts and ratios which are shown reflect income and expenses,
   including the  Portfolio's  proportionate share  of  the Series'  income  and
   expenses.
    
   
3) February  28, 1989 is  the date shares  of the Balanced  Portfolio were first
   sold to  the separate  accounts  pursuant to  the  public offering  of  Trust
   shares.
    
   
4) The amounts shown at this caption for a share outstanding throughout the year
   may  not accord with the  change in aggregate gains  and losses in securities
   for the year  because of  the timing of  sales and  repurchases of  Portfolio
   shares in relation to fluctuating market values for the Portfolio.
    
   
5) Not annualized.
    
   
6) Annualized.
    
   
7) Since  the  commencement of  operations,  N&B Management  voluntarily assumed
   certain operating expenses of the Portfolio  as described in Note B of  Notes
   to  Financial Statements and  in this Prospectus  under "Expense Limitation."
   Had N&B  Management not  undertaken  such action,  the annualized  ratios  of
   expenses  and net  investment income to  average daily net  assets would have
   been 2.78% and 2.20%, respectively, for the period from February 28, 1989  to
   December  31, 1989. There  was no reduction  of expenses for  the years ended
   December 31, 1990 through and including 1995.
    
   
8) The Portfolio transferred all of its investment securities into its Series on
   April 28, 1995. After that date the Portfolio invested only in its Series and
   that Series, rather than the  Portfolio, engaged in securities  transactions.
   Therefore,  after that date the Portfolio had no portfolio turnover rate. The
   portfolio turnover rate  for AMT  Balanced Investments  from May  1, 1995  to
   December 31, 1995 was 55%.
    
   
+ Total  return  based on  per share  net  asset value  reflects the  effects of
  changes in net  asset value on  the performance of  the Portfolio during  each
  year,  and  assumes dividends  and capital  gain  distributions, if  any, were
  reinvested. Results represent  past performance  and do  not guarantee  future
  results.  Total return figures would have been lower if N&B Management had not
  reimbursed certain expenses.  Investment returns and  principal may  fluctuate
  and  shares when redeemed  may be worth  more or less  than original cost. The
  total return information  shown does not  reflect expenses that  apply to  the
  separate account or the related insurance policies, and the inclusion of these
  charges  would reduce the total return  figures for all years shown. Qualified
  Plans that  are direct  shareholders  of the  Portfolio  are not  affected  by
  insurance charges.

  NOTES:
   
1) The per share amounts which are shown have been computed based on the average
   number of shares outstanding during each year.
    
   
2) The per share amounts and ratios which are shown reflect income and expenses,
   including the  Portfolio's  proportionate share  of  the Series'  income  and
   expenses.
    
   
3) On  May  2,  1988,  the  predecessor of  the  Portfolio  changed  its primary
   investment objective to obtain the highest current income consistent with low
   risk to principal and liquidity through investments in limited maturity  debt
   securities.
    
   
4) The  amounts shown  at this  caption for  a share  outstanding throughout the
   period may  not accord  with the  change  in aggregate  gains and  losses  in
   securities  for the period because of the  timing of sales and repurchases of
   Portfolio shares in relation to fluctuating market values for the Portfolio.
    
   
5) The Portfolio transferred all of its investment securities into its Series on
   April 28, 1995. After that date the Portfolio invested only in its Series and
   that Series, rather than the  Portfolio, engaged in securities  transactions.
   Therefore,  after that date the Portfolio had no portfolio turnover rate. The
   portfolio turnover rate  for AMT  Limited Maturity Bond  Investments for  the
   period from May 1, 1995 to December 31, 1995 was 78%.
    
   
+ Total  return  based on  per share  net  asset value  reflects the  effects of
  changes in net  asset value on  the performance of  the Portfolio during  each
  year  and  assumes  dividends and  capital  gain distributions,  if  any, were
  reinvested. Results represent  past performance  and do  not guarantee  future
  results.  Investment  returns  and  principal may  fluctuate  and  shares when
  redeemed may  be worth  more or  less  than original  cost. The  total  return
  information shown does not reflect expenses that apply to the separate account
  or the related insurance policies, and inclusion of these charges would reduce
  the total return figures for all years shown.

1) The per share amounts and ratios which are shown reflect income and expenses,
   including  the  Portfolio's proportionate  share  of the  Series'  income and
   expenses.
    
   
2) Since the  commencement  of  operations,  N&B  Management  or  the  principal
   underwriter  voluntarily assumed certain operating  expenses of the Portfolio
   as described  in  Note  B  of  Notes to  Financial  Statements  and  in  this
   Prospectus  under "Expense Limitation." Had  such action not been undertaken,
   the annualized ratios of expenses and net investment income to average  daily
   net  assets would have been 1.25% and 4.66%, respectively, for the year ended
   December 31, 1995, 1.03% and  3.27% in 1994, 1.03%  and 8.25% in 1989,  1.25%

   respectively. There was no reduction of expenses for the years ended December
   31, 1990 through and including 1993.

  would have been lower if N&B  Management had not reimbursed certain  expenses.

6) The Portfolio transferred all of its investment securities into its Series on
   April 28, 1995. After that date the Portfolio invested only in its Series and
   that Series, rather than the  Portfolio, engaged in securities  transactions.
   Therefore,  after that date the Portfolio had no portfolio turnover rate. The
   portfolio turnover rate for AMT Partners Investments for the period from  May
   1, 1995 to December 31, 1995 was 98%.
    
   
+ Total  return  based on  per share  net  asset value  reflects the  effects of
  changes in net  asset value on  the performance of  the Portfolio during  each
  year  and  assumes  dividends and  capital  gain distributions,  if  any, were
  reinvested. Results represent  past performance  and do  not guarantee  future
  results.  Investment  returns  and  principal may  fluctuate  and  shares when
  redeemed may  be worth  more or  less  than original  cost. The  total  return
  information shown does not reflect expenses that apply to the separate account
  or  the related insurance  policies, and the inclusion  of these charges would
  reduce the total return figures for all years shown.

INVESTMENT PROGRAMS
    
   
   The   investment  policies  and   limitations  of  each   Portfolio  and  its
corresponding  Series  are  identical.  Each  Portfolio  invests  only  in   its
corresponding Series. Therefore, the following shows you the kinds of securities
in  which each Series invests. For an  explanation of some types of investments,
see "Description of Investments" on page 35.
    
   Investment policies and limitations of the Portfolios and the Series are  not
fundamental  unless otherwise specified  in this Prospectus or  the SAI. While a
non-fundamental policy or limitation may be changed by the trustees of the Trust
or of  Managers Trust  without shareholder  approval, the  Portfolios intend  to
notify  shareholders  before  making any  material  change to  such  policies or
limitations. Fundamental policies  and limitations  may not  be changed  without
shareholder  approval.  There  can  be  no assurance  that  the  Series  and the
Portfolios will achieve their  objectives. Each Portfolio,  by itself, does  not
represent a comprehensive investment program.
   Additional  investment techniques,  features, and  limitations concerning the
Series' investment programs are described in the SAI.
 
          AMT Liquid Asset Investments
 
- --------------------------------------------------------------------------------
 
   The  investment  objective   of  AMT   Liquid  Asset   Investments  and   its
corresponding Portfolio is to provide the highest current income consistent with
safety  and liquidity. This  investment objective is fundamental  and may not be
changed without the  approval of the  holders of a  majority of the  outstanding
shares of the Portfolio and Series.
   AMT  Liquid Asset Investments invests in a portfolio of debt instruments with
remaining maturities of 397 days or less and maintains a dollar-weighted average
portfolio maturity of not more than 90 days. The Series uses the amortized  cost
method  of valuation to  enable the Portfolio  to maintain a  stable $1.00 share
price, which means that while Portfolio shares earn income, they should be worth
the same when the shareholder sells them  as when the shareholder buys them.  Of
course,  there is  no guarantee that  the Portfolio  will be able  to maintain a
$1.00 share price.
   AMT Liquid Asset Investments invests in high quality U.S.  dollar-denominated
money  market instruments of U.S. and foreign issuers, including governments and
their agencies and  instrumentalities, banks and  other financial  institutions,
and  corporations, and may invest in repurchase agreements with respect to these
instruments. The Series  may invest  25% or  more of  its total  assets in  U.S.
Government  and  Agency securities  or in  certificates  of deposit  or bankers'
acceptances issued by domestic branches of U.S. banks.
 
          AMT Limited Maturity Bond Investments
 
- --------------------------------------------------------------------------------
 
   The investment objective  of AMT  Limited Maturity Bond  Investments and  its
corresponding Portfolio is to provide the highest current income consistent with
low  risk  to  principal  and liquidity;  and  secondarily,  total  return. This
investment objective is fundamental and may not be changed without the  approval
of  the holders  of a majority  of the  outstanding shares of  the Portfolio and
Series.
   AMT Limited Maturity Bond Investments  invests in a diversified portfolio  of
fixed  and  variable  rate debt  securities  and  seeks to  increase  income and
preserve or enhance total return by actively managing average portfolio duration
in light of market conditions and trends.
   
   AMT Limited Maturity Bond Investments  invests in a diversified portfolio  of
short-to-intermediate-term  U.S.  Government  and  Agency  securities  and  debt
securities issued by financial institutions, corporations, and others, primarily
investment grade.  These  securities include  mortgage-backed  and  asset-backed
securities,  repurchase agreements  with respect  to U.S.  Government and Agency
securities, and foreign investments. AMT  Limited Maturity Bond Investments  may
invest  up to 10% of its net assets, measured at the time of investment, in debt
securities rated below investment grade, or in unrated securities determined  to
be of comparable quality by N&B Management
    
 
                                                                              15
<PAGE>
   
("comparable  unrated securities"). Debt  securities rated below  Baa by Moody's
Investors Services, Inc. ("Moody's") and below BBB by Standard & Poor's  Ratings
Group  ("S&P") are  considered to  be below  investment grade.  Securities rated
below investment  grade  as well  as  comparable unrated  securities  are  often
considered  to  be  speculative and  usually  entail greater  risk.  AMT Limited
Maturity Bond Investments will invest in  debt securities rated no lower than  B
by  Moody's or S&P  or comparable unrated securities.  AMT Limited Maturity Bond
Investments may invest  up to  5% of  its net assets,  measured at  the time  of
investment, in municipal securities when N&B Management believes such securities
may  outperform other available issues. The Series may purchase and sell covered
call and  put options,  interest-rate futures  contracts, and  options on  those
futures  contracts and may  engage in lending  portfolio securities. The Series'
dollar-weighted average portfolio duration may range up to four years. For  more
information  on  lower rated  securities, see  "Ratings  of Securities"  in this
Prospectus, "Fixed Income Securities" in the SAI, and Appendix A of the SAI.
    
 
          AMT Government Income Investments
 
- --------------------------------------------------------------------------------
 
   The investment  objective  of  AMT  Government  Income  Investments  and  its
corresponding  Portfolio is to provide a high  level of current income and total
return, consistent with safety of  principal. This investment objective is  non-
fundamental.  The Portfolio intends to notify shareholders 30 days in advance of
making any material change to its investment objective.
   AMT Government Income Investments invests in a diversified portfolio of fixed
and variable rate debt securities and  seeks to increase income and preserve  or
enhance total return by actively managing average portfolio duration in light of
market conditions and trends.
   AMT Government Income Investments invests at least 65% of its total assets in
U.S.  Government  and Agency  securities, with  an  emphasis on  U.S. Government
mortgage-backed securities. In addition, the Series invests at least 25% of  its
total   assets   in  mortgage-backed   securities  (including   U.S.  Government
mortgage-backed securities)  and asset-backed  securities. The  Series may  also
invest  in investment grade  debt securities, including  foreign investments and
securities issued by financial institutions  and corporations, and may  purchase
and  sell  covered  call and  put  options, interest-rate  and  foreign currency
futures contracts, and options on those futures contracts. Although there are no
restrictions on the  duration composition  of its portfolio  of securities,  the
Series  anticipates  that  it  normally  will  invest  in  intermediate-term and
longer-term securities, but will remain flexible to respond to market conditions
and interest rate trends. The Series may engage in lending portfolio securities,
short-term trading, purchasing forward commitments on securities, and repurchase
agreements, and  may use  leverage.  The investment  program  of the  Series  is
intended  to protect principal by focusing on the credit quality of the issuers.
Principal may, however, be at risk due to market rate fluctuations.
 
          AMT Growth Investments
 
- --------------------------------------------------------------------------------
 
   The investment  objective of  AMT Growth  Investments and  its  corresponding
Portfolio  is  to  seek  capital appreciation  without  regard  to  income. This
investment objective is fundamental and may not be changed without the  approval
of  the holders  of a majority  of the  outstanding shares of  the Portfolio and
Series.
   AMT Growth Investments generally invests  in securities believed to have  the
maximum potential for long-term capital appreciation. It does not seek to invest
in securities that pay dividends or interest, and any such income is incidental.
The  Series  expects to  be almost  fully  invested in  common stocks,  often of
companies that may be temporarily out of favor in the market.
 
16
<PAGE>
   
   The Series' aggressive growth investment  program involves greater risks  and
share   price  volatility  than  programs   that  invest  in  more  conservative
securities. Moreover, the Series does not follow a policy of active trading  for
short-term  profits.  Accordingly,  the  Series  may  be  more  appropriate  for
investors with  a longer-range  perspective.  The Series  uses  a "growth  at  a
reasonable  price"  investment  approach.  When  N&B  Management  believes  that
particular securities have greater potential for long-term capital appreciation,
the Series  may purchase  such securities  at prices  with higher  multiples  to
measures of economic value (such as earnings or cash flow) than other Series. In
addition,  the  Series  focuses  on companies  with  strong  balance  sheets and
reasonable valuations relative to  their growth rates.  It also diversifies  its
investments into many companies and industries.
    
 
          AMT Partners Investments
 
- --------------------------------------------------------------------------------
 
   The  investment objective of  AMT Partners Investments  and its corresponding
Portfolio  is   to   seek  capital   growth.   This  investment   objective   is
non-fundamental. The Portfolio intends to notify shareholders 30 days in advance
of making any material change to its investment objective.
   AMT  Partners Investments invests  primarily in common  stocks of established
companies, using  the  value-oriented  investment  approach.  The  Series  seeks
capital  growth  through an  investment approach  that  is designed  to increase
capital with reasonable risk. Its  investment program seeks securities  believed
to  be undervalued  based on strong  fundamentals such  as low price-to-earnings
ratios, consistent cash flow, and support from asset values.
   
   Up to 15% of the Series' net assets, measured at the time of investment,  may
be  invested in  corporate debt  securities rated  below investment  grade or in
unrated securities  determined to  be of  comparable quality  by N&B  Management
("comparable  unrated securities").  Securities rated below  investment grade as
well as comparable unrated securities are often considered to be speculative and
usually entail greater risk. For more information on lower rated securities, see
"Ratings of Securities"  in this  Prospectus, "Fixed Income  Securities" in  the
SAI, and Appendix A of the SAI.
    
 
          AMT Balanced Investments
 
- --------------------------------------------------------------------------------
 
   The  investment objective of  AMT Balanced Investments  and its corresponding
Portfolio is  long-term capital  growth and  reasonable current  income  without
undue risk to principal. This investment objective is fundamental and may not be
changed  without the approval  of the holders  of a majority  of the outstanding
shares of the Portfolio and Series.
   
   N&B Management  anticipates that  the Series'  investments will  normally  be
managed  so that approximately 60% of the  Series' total assets will be invested
in common stocks and the remaining  assets will be invested in debt  securities.
However,  depending on N&B  Management's views regarding  current market trends,
the common stock portion of the Series' investments may be adjusted downward  to
as  low as 50% or upward  to as high as 70%. At  least 25% of the Series' assets
will be invested in fixed income securities.
    
   
   N&B Management has analyzed the total return performance and volatility  over
the  last 36 years  of the Standard  & Poor's "500"  Composite Stock Price Index
("S&P 500"), an unmanaged average widely considered as representative of general
stock market performance. It has compared the performance and volatility of  the
S&P  "500" to that  of several model  balanced portfolios, each  consisting of a
different fixed  allocation of  the S&P  "500" and  U.S. Treasury  Notes  having
maturities  of 2 years. The comparison reveals that the model balanced portfolio
in which 60% was allocated  to the S&P "500" (with  the remaining 40% in  2-year
U.S.  Treasury Notes) was  able to achieve  88.4% of the  performance of the S&P
"500", with only  63.5% of the  volatility. Those model  balanced portfolios  in
which 70% and 50% were allocated to the S&P "500" were able to achieve 91.6% and
85.1%, respectively, of the performance of
    
 
                                                                              17
<PAGE>
the  S&P "500", with only 72.4% and 54.9% of the volatility, respectively. While
the underlying securities in the model balanced portfolios are not identical  to
the  anticipated  investments by  AMT  Balanced Investments  and  represent past
performance, N&B Management believes that the  results of its analysis show  the
potential  benefits of a balanced investment approach. A chart setting forth the
study appears as Appendix A to this Prospectus.
   
   In the common stock portion of its investments, AMT Balanced Investments will
utilize the same approach and  investment techniques employed by N&B  Management
in  managing AMT  Growth Investments,  by investing  in a  combination of common
stocks that N&B  Management believes  have the maximum  potential for  long-term
capital  appreciation. This  portion of  the Series does  not seek  to invest in
securities that pay dividends or interest, and any such income is incidental. In
the debt securities portion  of its investments,  AMT Balanced Investments  will
utilize  the same approach and investment  techniques employed by N&B Management
in managing AMT Limited Maturity Bond Investments, by investing in a diversified
portfolio of  limited duration  debt securities.  AMT Balanced  Investments  may
invest  up to 10% of the debt securities portion of its investments, measured at
the time of investment,  in debt securities rated  below investment grade or  in
unrated  securities determined  to be  of comparable  quality by  N&B Management
("comparable unrated securities").  Debt securities rated  below Baa by  Moody's
and  below BBB by  S&P are considered  to be below  investment grade. Securities
rated below investment grade as well as comparable unrated securities are  often
considered  to  be speculative  and usually  entail  greater risk.  AMT Balanced
Investments will invest in debt securities rated  no lower than B by Moody's  or
S&P  or  comparable  unrated securities.  For  more information  on  lower rated
securities, see  "Ratings  of  Securities" in  this  Prospectus,  "Fixed  Income
Securities" in the SAI, and Appendix A of the SAI.
    
 
          AMT International Investments
 
- --------------------------------------------------------------------------------
 
   The   investment  objective   of  AMT   International  Investments   and  its
corresponding Portfolio is to seek  long-term capital appreciation by  investing
primarily  in a diversified  portfolio of equity  securities of foreign issuers.
This investment  objective  is  non-fundamental.  Foreign  issuers  are  issuers
organized  and doing business principally outside  the U.S. and include non-U.S.
governments, their agencies, and instrumentalities.
   
   The Series  will invest  primarily in  equity securities  of  medium-to-large
capitalization  companies, determined  in relation to  their respective national
markets, traded on foreign  exchanges. The Series normally  invests in at  least
three  foreign countries. The strategy of N&B Management is to select attractive
investment opportunities outside the U.S.,  allocating the Series' assets  among
investments   in  economically  mature  countries  and  emerging  industrialized
countries. At least 65% of the Series' total assets normally will be invested in
equity securities of  foreign issuers.  The Series  may invest  more heavily  in
certain  countries than in  others. From time  to time, the  Series may invest a
significant part of  its assets in  Japan. See "Description  of Investments"  in
this Prospectus.
    
   The  Series may  also invest  in foreign securities  in the  form of American
Depositary  Receipts  (ADRs),  European   Depositary  Receipts  (EDRs),   Global
Depositary  Receipts (GDRs),  International Depositary Receipts  (IDRs) or other
similar securities representing  an interest in  securities of foreign  issuers,
and may purchase foreign corporate and government debt securities.
   
   Because the Portfolio, through its corresponding Series, invests primarily in
foreign  securities, it may be subject to greater risks and higher expenses than
equity funds that invest primarily in securities of U.S. issuers. Such risks may
be even greater in emerging industrialized and less developed countries.
    
   
   The risks of investing in foreign securities include, but are not limited to,
possible adverse political  and economic developments  in a particular  country,
differences  between foreign and U.S. regulatory systems, and foreign securities
markets that are smaller and less well-regulated than those in the U.S. There is
often less  information  publicly  available about  foreign  issuers,  and  many
foreign  countries do not follow the  financial accounting standards used in the
U.S.
    
 
18
<PAGE>
   
Most of  the  securities  held  by the  Portfolio  are  denominated  in  foreign
currencies,  and the  value of  these investments  can be  adversely affected by
fluctuations in foreign currency values. Some foreign currencies can be volatile
and may be subject to governmental  controls or intervention. The Portfolio  may
use  techniques  such as  options,  futures, forward  foreign  currency exchange
contracts ("forward contracts"), and short selling, for hedging purposes and  in
an  attempt to realize income. The Portfolio may also use leverage to facilitate
transactions entered into  by the  Portfolio for  hedging purposes.  The use  of
these strategies may entail special risks.
    
   For  more  details  about  investments of  the  Series,  see  "Description of
Investments" in this Prospectus.
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   AMT Government  Income Investments  may  engage in  short-term trading  to  a
substantial  degree to take advantage of  anticipated changes in interest rates.
This investment policy may be considered speculative. Although none of the other
Series purchases  securities with  the intention  of profiting  from  short-term
trading,  each Series may  sell portfolio securities prior  to maturity when the
investment adviser believes that such action is advisable.
   
   The portfolio turnover rates for the  Portfolios and the Series, and for  the
predecessors  of the  various Portfolios  for the period  prior to  May 1, 1995,
(except for Liquid  Asset Portfolio  and International Portfolio)  for 1995  and
earlier years are set forth under "Financial Highlights" in this Prospectus. The
portfolio  turnover rates  for the  Series are set  forth in  the Trust's annual
report to shareholders.
    
   
   It is anticipated that the annual  portfolio turnover rate of AMT  Government
Income  Investments and AMT Partners Investments  generally will exceed 100%. It
is anticipated that the annual portfolio turnover rate of AMT Growth Investments
and AMT Limited Maturity Bond Investments in some fiscal years may exceed 100%.
    
   Turnover rates in excess of 100% may result in higher costs (which are  borne
directly  by the Series) and a possible increase in short-term capital gains (or
losses).
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
    HIGH QUALITY DEBT SECURITIES (ALL SERIES). High quality debt securities  are
securities  that have received a rating  from at least one nationally recognized
statistical rating organization  ("NRSRO"), such  as Standard  & Poor's  Ratings
Group  ("S&P") or Moody's Investors Service, Inc. ("Moody's"), in one of the two
highest rating categories (the highest category in the case of commercial paper)
or, if not rated by  any NRSRO, such as  U.S. Government and Agency  securities,
have  been  determined by  N&B  Management to  be  of comparable  quality.  If a
security has been rated by  two or more NRSROs, at  least two of them must  have
given  the  security  a  high  quality rating  in  order  for  AMT  Liquid Asset
Investments to invest in that security.
 
   
    INVESTMENT GRADE  DEBT  SECURITIES  (ALL  SERIES  EXCEPT  AMT  LIQUID  ASSET
INVESTMENTS).  "Investment grade" debt securities are those receiving one of the
four highest ratings from Moody's, S&P, or  another NRSRO or, if unrated by  any
NRSRO,  deemed  comparable  by N&B  Management  to such  rated  securities under
guidelines  established  by  the  trustees  of  Managers  Trust.  Moody's  deems
securities  rated  in  its fourth  highest  category (Baa)  to  have speculative
characteristics; a change in economic factors could lead to a weakened  capacity
of the issuer to repay.
    
   If  the quality of securities held by any Series (other than AMT Liquid Asset
Investments) deteriorates so  that the  securities would no  longer satisfy  its
standards,  the Series will  engage in an orderly  disposition of the downgraded
securities to the extent necessary to  ensure that the Series' holdings of  such
securities  will  not exceed  5% of  the  Series' net  assets. AMT  Liquid Asset
Investments, in accordance with  Rule 2a-7 under the  Investment Company Act  of
1940, will consider disposing of its securities.
 
                                                                              19
<PAGE>
   
    LOWER-RATED  SECURITIES (AMT INTERNATIONAL,  BALANCED, LIMITED MATURITY BOND
AND PARTNERS INVESTMENTS). Debt  securities rated lower than  Baa by Moody's  or
BBB  by S&P and  debt securities determined  to be of  comparable quality by N&B
Management  ("comparable  unrated  securities")  are  considered  to  be   below
investment  grade. AMT International Investments may invest  up to 5% of its net
assets, measured at the time of  investment, in debt securities including  those
rated  below  investment grade  or  comparable unrated  securities.  AMT Limited
Maturity Bond Investments may invest  up to 10% of  its net assets, measured  at
the  time of  investment, in debt  securities rated below  investment grade, but
rated no lower than B by Moody's  or S&P, or comparable unrated securities.  AMT
Balanced  Investments may invest up to 10% of the debt securities portion of its
investments, measured at the time of investment, in debt securities rated  below
investment  grade, but rated  no lower than  B by Moody's  or S&P, or comparable
unrated securities. AMT  Partners Investments may  invest up to  15% of its  net
assets,  measured  at the  time of  investment, in  debt securities  rated below
investment grade  or  comparable  unrated  securities.  Securities  rated  below
investment  grade  ("junk bonds")  are  deemed by  Moody's  and S&P  (or foreign
statistical rating organizations) to  be predominantly speculative with  respect
to  the issuer's capacity to pay interest and repay principal in accordance with
the terms of the obligations.
    
   Those  debt  securities  in  the  lowest  rating  categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or  developments regarding the individual issuer  are more likely to cause price
volatility and weaken  the capacity of  the issuers of  such securities to  make
principal  and  interest  payments  than  is  the  case  for  higher  grade debt
securities. An economic downturn affecting the issuer may result in an increased
incidence of  default  and a  decline  in  prices of  the  issuer's  lower-rated
securities.  In the case of lower-rated  securities structured as zero-coupon or
pay-in-kind securities, their market prices are affected to a greater extent  by
interest  rate changes, and  therefore tend to be  more volatile than securities
that pay interest periodically and in cash.
   The market for lower-rated securities may be thinner and less active than for
higher-rated securities. The  secondary market  in which  debt securities  rated
below investment grade and comparable unrated securities are traded is generally
less  liquid than the market for higher grade debt securities. Less liquidity in
the secondary trading market could adversely affect the price at which a  Series
could sell a debt security rated below investment grade, or a comparable unrated
security,  and could adversely affect  the daily net asset  value of the Series'
shares. At times of  less liquidity, it  may be more difficult  to value a  debt
security rated below investment grade, or a comparable unrated security, because
such  valuation may require more  research, and elements of  judgment may play a
greater role in  the valuation because  there is less  reliable, objective  data
available.  N&B Management will invest in such securities only when it concludes
that the anticipated  return to  the Portfolio  on such  an investment  warrants
exposure  to the additional level of risk.  A further description of Moody's and
S&P's ratings is included in Appendix A to the SAI.
   The value  of the  fixed income  securities  in which  a Series  may  invest,
measured  in the currency in which they are denominated, is likely to decline in
times of rising  interest rates.  Conversely, when rates  fall, the  value of  a
Series'  fixed income investments  may rise. The longer  the period remaining to
maturity, the more  pronounced is  the effect of  interest rate  changes on  the
value of a security.
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   
    ALL SERIES (EXCEPT AMT GOVERNMENT INCOME AND AMT INTERNATIONAL INVESTMENTS).
Each of the Series has a fundamental policy that it may not borrow money, except
that  it may (1) borrow money from banks for temporary or emergency purposes and
not  for  leveraging  or  investment  and  (2)  enter  into  reverse  repurchase
agreements  for any purpose, so  long as the aggregate  amount of borrowings and
reverse repurchase agreements  does not  exceed one-third of  the Series'  total
assets (including the amount borrowed) less liabilities (other than borrowings).
None of these
    
 
20
<PAGE>
Series  expects  to borrow  money. As  a non-fundamental  policy, none  of these
Series  may  purchase  portfolio  securities  if  its  outstanding   borrowings,
including  reverse repurchase agreements, exceed 5%  of its total assets. Dollar
rolls are treated as reverse repurchase agreements.
 
   
    AMT GOVERNMENT INCOME INVESTMENTS. AMT  Government Income Investments, as  a
fundamental  policy, may borrow  money from banks for  any purpose, including to
meet redemptions and  increase the  amount available for  investment, and  enter
into  reverse repurchase agreements (including dollar rolls) for any purpose, so
long as the  aggregate amount  of borrowings and  reverse repurchase  agreements
does  not exceed  one-third of  the Series'  total assets  (including the amount
borrowed) less liabilities  (other than borrowings).  Leveraging (borrowing)  to
increase amounts available for investment may exaggerate the effect on net asset
value  of any increase or decrease in the  market value of the securities of the
Series. Money borrowed for  leveraging will be subject  to interest costs  which
may  or  may not  be  recovered by  income  and appreciation  of  the securities
purchased.
    
 
   
    AMT  INTERNATIONAL  INVESTMENTS.   AMT  International   Investments  has   a
fundamental  policy that it may not borrow  money, except that it may (1) borrow
money from  banks and  (2)  enter into  reverse  repurchase agreements  for  any
purpose,  so long as  the aggregate amount of  borrowings and reverse repurchase
agreements does not exceed one-third of the Series' total assets (including  the
amount borrowed) less liabilities (other than borrowings).
    
   The  Series may  borrow money from  banks to  facilitate transactions entered
into by the  Series for  hedging purposes,  which is  a form  of leverage.  This
leverage may exaggerate changes in the net asset value of the Portfolio's shares
and  the  gains and  losses on  the Series'  investments. Leverage  also creates
interest expenses;  if those  expenses exceed  the return  on transactions  that
borrowings facilitate, the Series will be in a worse position than if it had not
borrowed.  The use  of derivatives  in connection  with leverage  may create the
potential for significant  losses. The  Series may pledge  assets in  connection
with permitted borrowings.
 
   
    ALL SERIES. Currently, the State of California imposes borrowing limitations
on  variable insurance  product funds.  To comply  with these  limitations, each
Series, as a matter of operating policy, has undertaken that it will not  borrow
more  than 10% of its net asset value when borrowing for any general purpose and
will not  borrow more  than 25%  of  its net  asset value  when borrowing  as  a
temporary measure to facilitate redemptions. For these purposes, net asset value
is  the  market  value  of  all investments  or  assets  owned  less outstanding
liabilities at the time that any new or additional borrowing is undertaken.
    
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   
   For temporary  defensive  purposes,  all  Series  (except  AMT  International
Investments)  may each invest  up to 100% of  its total assets  in cash and cash
equivalents, U.S. Government and Agency Securities, commercial paper and certain
other money market instruments, as well as repurchase agreements  collateralized
by  the foregoing. Also, for temporary  defensive purposes, AMT Limited Maturity
Bond, Government Income and Balanced Investments (fixed income portion only) may
adopt shorter  weighted  average duration  than  normal, and  AMT  Liquid  Asset
Investments may adopt shorter weighted average maturity than normal.
    
   For temporary defensive purposes, AMT International Investments may invest up
to  100% of its total assets in  short-term foreign and U.S. investments such as
cash  or  cash  equivalents,  commercial  paper,  short-term  bank  obligations,
government  and agency securities and repurchase agreements. The Series may also
invest in such instruments to ensure adequate liquidity or to provide collateral
to be held in segregated accounts.
   To the extent that a Series  is invested in temporary defensive  instruments,
it will not be pursuing its investment objective.
 
                                                                              21
<PAGE>
          Duration
 
- --------------------------------------------------------------------------------
 
   Duration  is a measure  of the sensitivity  of debt securities  to changes in
market interest  rates,  based on  the  entire  cash flow  associated  with  the
securities,   including  payments  occurring  before   the  final  repayment  of
principal. N&B Management  utilizes duration  as a tool  in portfolio  selection
instead of the more traditional measure known as "term to maturity" in portfolio
selection  for AMT Limited Maturity Bond  and AMT Government Income Investments,
and for  the debt  securities  portion of  AMT  Balanced Investments.  "Term  to
maturity"  measures  only the  time  until a  debt  security provides  its final
payment, taking no account  of the pattern of  the security's payments prior  to
maturity.  Duration incorporates a bond's yield, coupon interest payments, final
maturity and call features into one measure. Duration therefore provides a  more
accurate  measurement of  a bond's  likely price change  in response  to a given
change in market interest rates. The longer the duration, the greater the bond's
price movement will be as interest  rates change. For any fixed income  security
with  interest payments occurring prior to the payment of principal, duration is
always less than maturity.
   
   Futures, options, and options on  futures have durations which are  generally
related  to the duration of the securities underlying them. Holding long futures
or call option positions will lengthen  a Series' duration by approximately  the
same  amount as would holding an equivalent amount of the underlying securities.
Short futures  or put  options  have durations  roughly  equal to  the  negative
duration of the securities that underlie these positions, and have the effect of
reducing portfolio duration by approximately the same amount as would selling an
equivalent amount of the underlying securities.
    
   There  are some situations where even  the standard duration calculation does
not properly reflect  the interest  rate exposure  of a  security. For  example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon  reset. Another example where the  interest rate exposure is not properly
captured by duration is the case of mortgage-backed securities. The stated final
maturity of such securities is generally 30 years, but current prepayment  rates
are critical in determining the securities' interest rate exposure. In these and
other  similar  situations,  N&B  Management,  where  permitted,  will  use more
sophisticated analytical  techniques that  incorporate the  economic life  of  a
security into the determination of its interest rate exposure.

PERFORMANCE INFORMATION
 
    LIQUID  ASSET PORTFOLIO.  From time  to time,  the Liquid  Asset Portfolio's
annualized "yield" and "effective yield" may be presented in advertisements  and
sales  literature. The  Portfolio's "yield"  represents an  annualization of the
increase in value of an account (excluding any capital changes) invested in  the
Portfolio  for a  specific seven-day  period. The  Portfolio's "effective yield"
compounds such yield for a year and thus is greater than the Portfolio's yield.
   
    OTHER PORTFOLIOS. Performance information for  each of the other  Portfolios
may  be presented from  time to time  in advertisements and  sales literature. A
Portfolio's "yield" is  calculated by  dividing the  Portfolio's annualized  net
investment  income during  a recent 30-day  period by the  Portfolio's net asset
value on the last day  of the period. A Portfolio's  total return is quoted  for
the  one-year period  and, where applicable,  the five-year  period and ten-year
period through  the  most  recent calendar  quarter  (or  for the  life  of  the
Portfolio,  if less than ten years) and  is determined by calculating the change
in value of a hypothetical $1,000 investment in the Portfolio for each of  those
periods.   Total  return  calculations  assume  reinvestment  of  all  Portfolio
dividends and distributions from net  investment income and net realized  gains,
respectively.
    
   All  performance information  presented for the  Portfolios is  based on past
performance and does not predict  future performance. Any Portfolio  performance
information  presented  will  also  include  or  be  accompanied  by performance
information for the Life Company separate accounts investing in the Trust  which
will  take  into  account  insurance-related  charges  and  expenses  under such
insurance policies and contracts. Further information regarding each Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of one  or more  Portfolios to various  indices. Advertisements  may
also  contain  the performance  rankings  assigned certain  Portfolios  or their
advisers by various publications and statistical services. Any such  comparisons
or  rankings  are based  on past  performance  and the  statistical computations
performed by publications and services,  and are not necessarily indications  of
future  performance.  Because  the Portfolios  are  managed  investment vehicles
investing in a wide variety of  securities, the securities owned by a  Portfolio
will  not match those making  up an index. Please note  that indices do not take
into account any  fees and expenses  of investing in  the individual  securities
that they track and that individuals cannot invest in any index.

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   Each  Portfolio is a separate series of  the Trust, a Delaware business trust
organized pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust  is
registered  under  the Investment  Company Act  of  1940 (the  "1940 Act")  as a
diversified, open-end management investment company, commonly known as a  mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of the  International  Portfolio which  as  of December  31,  1995 had  not  yet
commenced   investment  operations.  These  conversions  were  approved  by  the
shareholders of  the  predecessors  of  the  Portfolios  in  August  1994.  Each
Portfolio  invests all of its net investable assets in its corresponding Series,
in each case receiving a beneficial interest in that Series. The trustees of the
Trust may  establish additional  portfolios or  classes of  shares, without  the
approval  of  shareholders. The  assets of  each Portfolio  belong only  to that
Portfolio, and  the liabilities  of  each Portfolio  are  borne solely  by  that
Portfolio and no other.
   
    DESCRIPTION  OF SHARES. Each  Portfolio is authorized  to issue an unlimited
number of shares of beneficial interest (par value $0.001 per share). Shares  of
each  Portfolio represent  equal proportionate interests  in the  assets of that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law, and shareholders  have no  preemptive or other  right to  subscribe to  any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings  of  shareholders of  the Portfolios.  The  trustees will  call special
meetings of shareholders of a Portfolio only  if required under the 1940 Act  or
in their discretion or upon the written request of holders of 10% or more of the
outstanding  shares  of that  Portfolio entitled  to  vote. Pursuant  to current
interpretations of  the  1940  Act,  the  Life  Companies  will  solicit  voting
instructions  from Variable Contract owners with respect to any matters that are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any  Portfolio; a  shareholder is  entitled to  the same  limitation of personal
liability extended to shareholders  of corporations. To  guard against the  risk
that  Delaware law might  not be applied  in other states,  the Trust Instrument
requires that every  written obligation of  the Trust or  a Portfolio contain  a
statement  that such obligation may  be enforced only against  the assets of the
Trust or Portfolio and  provides for indemnification out  of Trust or  Portfolio
property  of any  shareholder nevertheless held  personally liable  for Trust or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each Series is a  separate series of  Managers Trust, a  New York common  law
trust  organized as of May 24, 1994. Managers Trust is registered under the 1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International  Portfolio which  as of  December 31,  1995 had  not yet commenced
investment  operations)  invested  all  of  its  net  investable  assets  (cash,
securities, and receivables relating to securities) in a corresponding Series of
Managers  Trust, receiving a  beneficial interest in that  Series. The assets of
each Series belong only to that Series,  and the liabilities of each Series  are
borne solely by that Series and no other.
    
 
24
<PAGE>
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor in a Series other than a Portfolio redeemed its interest in the Series,
the  Series' remaining investors  (including the Portfolio)  might, as a result,
experience higher pro rata operating expenses, thereby producing lower returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a Portfolio withdrew its investment from a Series, the trustees  would
consider  what action  might be  taken, including the  investment of  all of the
Portfolio's net investable  assets in  another pooled  investment entity  having
substantially the same investment objective as the Portfolio or the retention by
the  Portfolio of its own investment manager  to manage its assets in accordance
with its investment objective, policies,  and limitations. The inability of  the
Portfolio  to find  a suitable  replacement could  have a  significant impact on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors except as required by the 1940 Act. Each investor in a Series will  be
entitled  to  vote in  proportion  to its  relative  beneficial interest  in the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act and  other  applicable  law,  a Portfolio  will  solicit  proxies  from  its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the Portfolio's shareholders. Pursuant to current interpretations of the
1940  Act, the Life Companies who are shareholders of the Portfolio will solicit
voting instructions from contract  owners with respect to  any matters that  are
presented to a vote of Portfolio shareholders. If there are other investors in a
Series, there can be no assurance that any issue that receives a majority of the
votes  cast by Portfolio shareholders  will receive a majority  of votes cast by
all Series investors; indeed, if other investors hold a majority interest in the
Series, they could have voting control of the Series.
 
                                                                              25
<PAGE>
    CERTAIN PROVISIONS. Each investor in  a Series, including a Portfolio,  will
be  liable  for all  obligations of  the Series,  but not  of the  other Series.
However, the risk of an investor in a Series incurring financial loss on account
of such liability  would be  limited to circumstances  in which  the Series  had
inadequate  insurance and was unable to meet  its obligations out of its assets.
Upon liquidation of a Series, investors would  be entitled to share pro rata  in
the net assets of the Series available for distribution to investors.

<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net  asset  value  ("NAV")  per  share. The  NAVs  for  each  Portfolio  and its
corresponding Series are calculated by subtracting liabilities from total assets
(in the case of a  Series, the market value of  the securities the Series  holds
plus  cash and other assets; in the case of a Portfolio, its percentage interest
in its  corresponding Series,  multiplied by  the Series'  NAV, plus  any  other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number  of Portfolio shares  outstanding and rounding the  result to the nearest
full cent.
   Each Portfolio and its  corresponding Series calculate their  NAVs as of  the
close of regular trading on The New York Stock Exchange ("NYSE"), usually 4 p.m.
Eastern  time. AMT Liquid Asset Investments,  in accordance with Rule 2a-7 under
the 1940 Act,  will use the  amortized cost  method of valuation  to enable  AMT
Liquid Asset Investments to try to maintain a stable NAV of $1.00 per share. AMT
Liquid  Asset Investments  values its  securities at their  cost at  the time of
purchase and assumes  a constant  amortization to  maturity of  any discount  or
premium.
   
   AMT  Limited Maturity Bond, Government Income, and Balanced Investments (debt
securities portion)  generally  value  their  securities on  the  basis  of  bid
quotations  from independent pricing services or principal market makers, or, if
quotations are not available,  by a method that  the trustees of Managers  Trust
believe   accurately  reflects  fair  value.   The  Series  periodically  verify
valuations  provided  by  the  pricing  services.  Short-term  securities   with
remaining  maturities  of less  than  60 days  are  valued at  cost  which, when
combined with interest earned, approximates market value.
    
   
   AMT Growth, Partners, and Balanced  Investments (equity portion) value  their
equity  securities (including  options) listed on  the NYSE,  the American Stock
Exchange, other national exchanges, or  the NASDAQ market, and other  securities
for  which market quotations are readily available,  at the latest sale price on
the day NAV is calculated. If there is  no sale of such a security on that  day,
that  security is valued at  the mean between its  closing bid and asked prices.
The  Series  value  all  other  securities  and  assets,  including   restricted
securities,  by a method that the  trustees of Managers Trust believe accurately
reflects fair value.
    
   Equity securities held  by AMT  International Investments are  valued at  the
last  sale price on the principal  exchange or in the principal over-the-counter
market in which such securities are traded,  as of the close of business on  the
day  the securities  are being  valued, or if  there are  no sales,  at the last
available bid price. Debt obligations held by AMT International Investments  are
valued  at the last available  bid price for such  securities, or if such prices
are not available, at prices for securities of comparable maturity, quality, and
type. Foreign  securities  are translated  from  the local  currency  into  U.S.
dollars  using current exchange rates.  AMT International Investments values all
other types  of  securities  and assets,  including  restricted  securities  and
securities  for which market  quotations are not readily  available, by a method
that the trustees of Managers Trust believe accurately reflects fair value.  AMT
International  Investments' portfolio securities are listed primarily on foreign
exchanges which may trade on days when the NYSE is closed. As a result, the  NAV
of  the  International  Portfolio may  be  significantly affected  on  days when
shareholders have no access to the Portfolio.
 
                                                                              27
<PAGE>
DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   Each of the Government Income,  Growth, Partners, Balanced, Limited  Maturity
Bond, and International Portfolios annually distributes substantially all of its
share of its corresponding Series' net investment income (net of the Portfolio's
expenses),  net  realized capital  gains, and  net  realized gains  from foreign
currency transactions, if any, normally in February.
   The Liquid Asset Portfolio distributes to its shareholders substantially  all
of  its share  of its  corresponding Series' net  investment income  (net of the
Portfolio's expenses)  and  net realized  capital  gains. Income  dividends  are
declared  daily for the Portfolio at the time its NAV is calculated and are paid
monthly, and  net  realized capital  gains,  if any,  are  normally  distributed
annually in February.
   The  Portfolios offer  their shares solely  to separate accounts  of the Life
Companies, except for  the Balanced Portfolio  which also offers  its shares  to
Qualified  Plans. All dividends  and other distributions  are distributed to the
separate accounts (and, with respect to the Balanced Portfolio, to the Qualified
Plans) and will be automatically invested  in Trust shares. Dividends and  other
distributions  made by a Portfolio  to the separate accounts  are taxable, if at
all, to the extent described in the prospectuses for the Variable Contracts.
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio  is  treated as  a  separate  entity for  Federal  income  tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986,  as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) and net  capital gain (the  excess of net  long-term capital  gain
over  net short-term capital loss) that is distributed to its shareholders. Each
Portfolio intends  to  distribute  all  of  its net  income  and  gains  to  its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service  that  each  Portfolio, as  an  investor  in a  corresponding  Series of
Managers Trust,  will be  deemed to  own a  proportionate share  of the  Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will  be treated as a  separate partnership for Federal  income tax purposes and
will not be a "publicly traded partnership," with the result that none of  those
Series  will  be subject  to  Federal income  tax  (and, instead,  each investor
therein will take into account in  determining its Federal income tax  liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The  foregoing is only a summary of  some of the important Federal income tax
considerations generally affecting  the Portfolios and  their shareholders;  see
the  SAI for a  more detailed discussion. Prospective  shareholders are urged to
consult their tax advisers.

<PAGE>
SPECIAL CONSIDERATIONS
   The Portfolios serve  as the  underlying investments  for Variable  Contracts
issued  through separate accounts of the Life  Companies which may or may not be
affiliated.  See  "Distribution  and  Redemption   of  Trust  Shares"  in   this
Prospectus.
   Section  817(h) of the Code imposes  certain diversification standards on the
underlying assets of segregated asset accounts  that fund contracts such as  the
Variable Contracts (that is, the assets of the Series), which are in addition to
the  diversification requirements imposed on the  Portfolios by the 1940 Act and
Subchapter M. Failure to satisfy those  standards would result in imposition  of
Federal  income tax on a Variable Contract owner with respect to the increase in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset account that funds contracts such as the Variable Contracts is treated  as
meeting  the  diversification standards  if, as  of the  close of  each calendar
quarter, the assets in the account  meet the diversification requirements for  a
regulated  investment company and  no more than  55% of those  assets consist of
cash, cash items, U.S. Government  securities and securities of other  regulated
investment companies.
   The  Treasury Regulations amplify the  diversification standards set forth in
Section 817(h)  and provide  an alternative  to the  provision described  above.
Under  the  regulations,  an  investment  portfolio  will  be  deemed adequately
diversified if (i)  no more than  55% of the  value of the  total assets of  the
portfolio  is represented by any  one investment; (ii) no  more than 70% of such
value is represented  by any two  investments; (iii)  no more than  80% of  such
value is represented by any three investments; and (iv) no more than 90% of such
value  is represented by any four investments. For purposes of these Regulations
all securities of the same issuer are  treated as a single investment, but  each
United  States  government  agency  or instrumentality  shall  be  treated  as a
separate issuer.
   
   Each Series  will be  managed  with the  intention  of complying  with  these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   Section  817  of the  Code  and the  Treasury  Regulations thereunder  do not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder  fund structure. As described under  "Tax Status" above, the Trust
and Managers Trust  have received  a ruling  from the  Internal Revenue  Service
concluding  that the "look-through" rule of  Section 817, which would permit the
segregated asset  accounts to  look  through to  the  underlying assets  of  the
Series, will be available for the variable contract diversification test.
   Currently,  the State  of California imposes  diversification requirements on
variable insurance products funds investing in non-U.S. securities. Under  these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must  be invested in at least five countries; less than 80% but at least 60%, in
at least four  countries; less  than 60%  but at least  40%, in  at least  three
countries; and less than 40% but at least 20%, in at least two countries, except
that  up to  35% of  a fund's assets  may be  invested in  securities of issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United Kingdom or Germany.  The Trust and Managers  Trust intend to comply  with
the California diversification requirements, to the extent applicable.
 
                                                                              29

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.

    ALL PORTFOLIOS AND THEIR CORRESPONDING SERIES. N&B Management serves as  the
investment  manager of each  Series, as administrator of  each Portfolio, and as
distributor of the shares of each Portfolio. N&B Management and its  predecessor
firms  have specialized in the management of no-load mutual funds since 1950. In
addition to  serving  the  seven  Series, N&B  Management  currently  serves  as
investment    manager   or   investment   adviser   of   other   mutual   funds.
Neuberger&Berman, which  acts as  sub-adviser for  the Series  and other  mutual
funds  managed by  N&B Management,  also serves  as investment  adviser of three
other  investment  companies.   These  funds   had  aggregate   net  assets   of
approximately $11.9 billion as of December 31, 1995.
    
   
   As  sub-adviser,  Neuberger&Berman furnishes  N&B Management  with investment
recommendations and  research  information without  added  cost to  the  Series.
Neuberger&Berman  is a member firm of the NYSE and other principal exchanges and
acts as  the Series'  principal broker  in the  purchase and  sale of  portfolio

Portfolio  has authorized the  distributor to give only  such information and to
make  only  such  statements  and  representations  as  are  contained  in   the

commissions. In effecting securities transactions,  each Series seeks to  obtain
the best price and execution of orders. For more information, see the SAI.

   The  partners and employees of Neuberger&Berman and officers and employees of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&BermanFunds.
   To mitigate  the possibility  that a  Series will  be adversely  affected  by
personal  trading of employees,  the Trust, Managers  Trust, N&B Management, and
Neuberger&Berman have  adopted  policies  that regulate  securities  trading  in
personal  accounts of the  portfolio managers and others  who normally come into
possession of information on portfolio  transactions. These policies comply,  in
all  material  respects,  with  the recommendations  of  the  Investment Company
Institute.

   Each Portfolio bears all expenses of its operations other than those borne by
N&B  Management  as administrator  of the  Portfolio and  as distributor  of its
shares. Each Series bears all expenses of its operations other than those  borne
by  N&B Management as investment manager  of the Series. These expenses include,
but are not limited to, for the Portfolios and the Series, legal and  accounting
fees  and compensation for trustees who  are not affiliated with N&B Management;
for the Portfolios,  transfer agent fees  and the cost  of printing and  sending
reports  and proxy materials to shareholders; and for the Series, custodial fees
for securities. Any expenses which are  not directly attributable to a  specific
Series are allocated on the basis of the net assets of the respective Series.
 
   
          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
    ALL   PORTFOLIOS  AND  THEIR   CORRESPONDING  SERIES  (EXCEPT  INTERNATIONAL
PORTFOLIO AND ITS CORRESPONDING SERIES). N&B Management has undertaken to  limit
the  Portfolios'  expenses  by  reimbursing  each  Portfolio  for  its operating
expenses and its pro rata share of its corresponding Series' operating expenses,
excluding the compensation of N&B Management (with respect to all Portfolios but
the  Liquid  Asset  Portfolio  and  the  Government  Income  Portfolio),  taxes,
interest,  extraordinary expenses, brokerage  commissions and transaction costs,
that  exceed  1%  of  the  Portfolio's  average  daily  net  asset  value.  This
undertaking  is subject to termination  on 60 days' prior  written notice to the
Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses of a Portfolio and its corresponding Series and thereby increase  total
return.
    
 
   
    INTERNATIONAL PORTFOLIO AND ITS CORRESPONDING SERIES. From November 30, 1995
through   December  31,  1996,  N&B  Management  has  undertaken  to  limit  the
Portfolio's expenses by reimbursing the Portfolio for operating expenses and its
pro rata  share  of  its corresponding  Series'  operating  expenses,  including
compensation  to N&B  Management, but  excluding taxes,  interest, extraordinary
expenses and brokerage commissions, that exceed 1.70% of the Portfolio's average
daily net asset  value ("Portfolio  Expense Limitation"). The  Portfolio has  in
turn agreed to repay through December 31, 1997, expenses borne by N&B Management
pursuant  to the previous sentence, so  long as the Portfolio Expense Limitation
is not exceeded. The effect of any expense limitation on the Portfolio or Series
would be  to reduce  the Portfolio's  expenses and  thereby increase  its  total
return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   State  Street Bank and Trust Company ("State Street"), Boston, Massachusetts,
acts as transfer and dividend  paying agent for the  Portfolios and in so  doing
performs  certain  bookkeeping,  data  processing  and  administrative services.
Qualified Plan participants investing in the Balanced Portfolio should send  all
correspondence  to State Street,  care of Boston Service  Center, P.O. Box 8403,
Boston, MA 02266-8403. All other correspondence  should be sent to State  Street
Bank  & Trust Company,  P.O. Box 1978,  Boston, MA 02105.  State Street provides
similar services to the Series as the Series' transfer agent. State Street  also
acts as the custodian of the Series' and the Portfolios' assets.
 
                                                                              33
<PAGE>
DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and  payments under the  Variable Contracts issued  through separate accounts of
the Life Companies which may or may not be affiliated with the Trust. Shares  of
the  Balanced  Portfolio of  the Trust  are also  offered directly  to Qualified
Plans. Shares of the Trust are purchased and redeemed at net asset value.
   The Boards of  Trustees of the  Trust and Managers  Trust have undertaken  to
monitor  the Trust  and Managers Trust,  respectively, for the  existence of any
material irreconcilable conflict between the interests of the Variable  Contract
owners  of the Life  Companies and to  determine what action,  if any, should be
taken in the  event of a  conflict. The  Life Companies and  N&B Management  are
responsible for reporting any potential or existing conflicts to the Boards. Due
to  differences of tax  treatment and other  considerations, it is theoretically
possible that the interests of various Variable Contract owners participating in
the Trust and Managers Trust and  the interests of Qualified Plans investing  in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or  more Life  Company separate accounts  or Qualified Plans  might withdraw its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions will be  effected by  the separate accounts  to meet  obligations
under  the Variable Contracts and by the Qualified Plans. Contract owners do not
deal directly  with the  Trust  with respect  to  acquisition or  redemption  of
shares.  The trustees of the Trust may refuse to sell shares of any Portfolio to
any person, or suspend or terminate the  offering of shares of any Portfolio  if
such  action is required by law or by regulatory authorities having jurisdiction
or is, in the sole discretion of the trustees acting in good faith and in  light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The  Board of Trustees of  the Trust has adopted  a non-fee Distribution Plan
for each Portfolio of the Trust.
   The Distribution Plan recognizes that N&B  Management may use its assets  and
resources,  including its profits from administration  fees paid by a Portfolio,
to pay expenses associated with  the distribution of Portfolio shares.  However,
N&B  Management will  not receive  any separate fees  for such  expenses. To the
extent that any payments  made by a  Portfolio should be  deemed to be  indirect
financing  of any activity primarily intended to result in the sale of shares of
the Portfolio within the  context of Rule  12b-1 under the  1940 Act, then  such
payments shall be deemed to be authorized by the Distribution Plan.
   Under  the Distribution  Plan, the Portfolio  will require  N&B Management to
provide the Trust with quarterly reports  of the amounts expended in  connection
with  financing  any  activity  primarily  intended to  result  in  the  sale of
Portfolio shares,  and the  purpose for  which such  expenditure was  made.  The
Distribution  Plan may be terminated as to a particular Portfolio at any time by
a vote of a majority of the independent trustees of the Trust or by a vote of  a
majority   of  the  outstanding   voting  securities  of   that  Portfolio.  The
Distribution Plan does not require N&B  Management to perform any specific  type
or  level of distribution activities or to  incur any specific level of expenses
for activities  primarily  intended to  result  in the  sale  of shares  of  the
Portfolio.

DESCRIPTION OF INVESTMENTS
   In  addition to the  securities referred to  in "Investment Programs" herein,
some or  all  of  the  Series,  as  indicated  below,  may  make  the  following
investments, among others, individually or in combination, although a Series may
not  necessarily buy any or all of the types  of securities or use any or all of
the investment techniques that are  described. These investments may be  limited
by  the requirements with which the Series  must comply if the Portfolios are to
qualify as regulated investment companies for  tax purposes. The use of  hedging
or other techniques is discretionary and no representation is made that the risk
of  any Series will be reduced by  the techniques discussed in this section. For
additional information  on  the following  investments  and on  other  types  of
investments the Series may make, see the SAI.
 
    U.S.   GOVERNMENT  AND  AGENCY  SECURITIES  (ALL  SERIES).  U.S.  Government
securities are obligations  of the  U.S.Treasury backed  by the  full faith  and
credit  of the  United States. U.S.  Government Agency securities  are issued or
guaranteed  by  U.S.  Government  agencies,  instrumentalities,  or  other  U.S.
Government-sponsored  enterprises,  such  as  the  Government  National Mortgage
Association ("GNMA"), Federal  National Mortgage  Association ("FNMA"),  Federal
Home  Loan Mortgage  Corporation ("FHLMC"), Student  Loan Marketing Association,
Tennessee Valley Authority, and various federally chartered or sponsored  banks.
Agency  securities may  be backed  by the  full faith  and credit  of the United
States, the issuer's ability  to borrow from the  U.S. Treasury, subject to  the
Treasury's  discretion in certain  cases, or only  by the credit  of the issuer.
U.S.  Government   and  Agency   securities  include   certain   mortgage-backed
securities.  The market prices of U.S.  Government securities are not guaranteed
by the government and generally fluctuate with changing interest rates.
 
    ILLIQUID SECURITIES (ALL SERIES).  Each Series may invest  up to 10% of  its
net  assets in securities that are illiquid,  in that they cannot be expected to
be sold within seven days at approximately  the price at which they are  valued.
Due  to  the  absence of  an  active  trading market,  a  Series  may experience
difficulty in  valuing  or  disposing of  illiquid  securities.  N&B  Management
determines  the liquidity  of the Series'  securities, under  supervision of the
trustees of  Managers Trust.  Securities  which are  freely tradeable  in  their
country  of origin or in their principal  market will not be considered illiquid
securities even if they are not registered for sale in the U.S.
 
    FOREIGN  SECURITIES   (ALL  SERIES).   All  Series   may  invest   in   U.S.
dollar-denominated  foreign securities. Foreign securities  are those of issuers
organized and doing  business principally outside  the U.S., including  non-U.S.
governments,  their  agencies,  and instrumentalities.  All  Series,  except AMT
Liquid Asset Investments, may also  invest in foreign securities denominated  in
or  indexed to foreign currencies, which may also be affected by the fluctuation
of the  foreign currencies  relative to  the U.S.  dollar, irrespective  of  the
performance of the underlying investment. N&B Management considers these factors
in  making  investments for  the Series.  AMT  Limited Maturity  Bond, Balanced,
International and Government Income Investments  may enter into forward  foreign
currency contracts or futures contracts (agreements to exchange one currency for
another  at a future date)  and related options to  manage currency risks and to
facilitate transactions  in foreign  securities.  Although these  contracts  can
protect  the Series from adverse  exchange rate changes, they  involve a risk of
loss if N&B Management fails to predict foreign currency values correctly.
   
   AMT Growth, Partners and  Balanced Investments may each  invest up to 10%  of
the  value of its total  assets, measured at the  time of investment, in foreign
securities that are  issued by  non-United States entities.  The 10%  limitation
does  not apply with respect to foreign  securities that are denominated in U.S.
dollars, including ADRs. Foreign securities (including those denominated in U.S.
dollars and ADRs) are affected by political or economic developments in  foreign
countries.
    
   AMT  International Investments may invest in ADRs, EDRs, GDRs, and IDRs. ADRs
(sponsored or unsponsored) are receipts typically issued by a U.S. bank or trust
company evidencing its ownership of the underlying foreign
 
                                                                              35
<PAGE>
securities. Most ADRs are denominated in U.S.  dollars and are traded on a  U.S.
stock  exchange. Issuers of  the securities underlying  unsponsored ADRs are not
contractually obligated  to  disclose  material information  in  the  U.S.  and,
therefore,  there  may not  be a  correlation between  such information  and the
market value of the unsponsored ADR. EDRs and IDRs are receipts typically issued
by a European bank or trust  company evidencing its ownership of the  underlying
foreign  securities.  GDRs are  receipts  issued by  either  a U.S.  or non-U.S.
banking  institution  evidencing  its   ownership  of  the  underlying   foreign
securities and are often denominated in U.S. dollars.
   Investments  in foreign securities could be affected by factors generally not
thought to be present in the U.S. Such factors include, but are not limited  to,
varying  custody, brokerage and settlement practices; difficulty in pricing some
foreign securities; less  public information about  issuers of securities;  less
governmental regulation and supervision over issuance and trading of securities;
the  unavailability of financial  information or the  difficulty of interpreting
financial  information  prepared  under   foreign  accounting  standards;   less
liquidity  and more volatility in foreign securities markets; the possibility of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or  diplomatic developments;  limitations on  the movement  of funds  or
other assets of the Series between different countries; difficulties in invoking
legal  process abroad and enforcing  contractual obligations; and the difficulty
of assessing  economic  trends  in  foreign  countries.  Investment  in  foreign
securities  also  involves higher  brokerage  and custodian  expenses  than does
investment in domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve other  risks  which are  not  ordinarily associated  with  investing  in
domestic  securities. These risks include changes in currency exchange rates and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions   applicable  to  such  investments   or  devaluations  of  foreign
currencies. A decline  in the exchange  rate would reduce  the value of  certain
portfolio   securities  irrespective  of  the   performance  of  the  underlying
investment. In addition, a Series may incur costs in connection with  conversion
between  various currencies. Investments in  depositary receipts (whether or not
denominated in U.S. dollars) may be subject to exchange controls and changes  in
rates  of  exchange with  the  U.S. dollar  because  the underlying  security is
usually denominated  in foreign  currency. All  of the  foregoing risks  may  be
intensified in emerging industrialized and less developed countries.
 
   
    JAPANESE  INVESTMENTS  (AMT  INTERNATIONAL  INVESTMENTS).  AMT International
Investments may invest  a substantial  portion of  its assets  in securities  of
Japanese   issuers.  The   performance  of   the  Portfolio   may  therefore  be
significantly affected by events affecting the Japanese economy and the exchange
rate between  the Japanese  yen and  the U.S.  dollar. Japan  has experienced  a
severe  recession, including  a decline in  real estate values  and other events
that adversely affected the  balance sheets of  many financial institutions  and
indicate  that  there may  be structural  weaknesses  in the  Japanese financial
system. The effects  of this economic  downturn may be  felt for a  considerable
period  and  are  being exacerbated  by  the  currency exchange  rate.  Japan is
undergoing a period of political instability, which may undercut its ability  to
promptly  resolve trading disputes  with the U.S. Japan  is heavily dependent on
foreign oil.  Japan  is  located  in  a  seismically  active  area,  and  severe
earthquakes  may  damage  important elements  of  the  country's infrastructure.
Japanese economic  prospects  may be  affected  by the  political  and  military
situations  of  its near  neighbors, notably  North and  South Korea,  China and
Russia.
    
 
    FOREIGN  CORPORATE  AND  GOVERNMENT   DEBT  SECURITIES  (AMT   INTERNATIONAL
INVESTMENTS).  The Series may invest up to 5% of its net assets, measured at the
time of investment, in  U.S. dollar-denominated and non-U.S.  dollar-denominated
corporate  and government  debt securities  of foreign  issuers. The  Series may
invest in debt securities of any rating, including those rated below  investment
grade and unrated securities.
 
    FOREIGN   CURRENCY  TRANSACTIONS   (ALL  SERIES  EXCEPT   AMT  LIQUID  ASSET
INVESTMENTS). Each  of these  Series  may enter  into forward  foreign  currency
exchange contracts in order to protect against adverse changes in future foreign
currency exchange rates, to facilitate transactions in foreign securities and to
repatriate dividend or interest income
 
36
<PAGE>
received  in foreign currencies.  A Series may enter  into contracts to purchase
foreign currencies to  protect against an  anticipated rise in  the U.S.  dollar
price  of  securities it  intends  to purchase.  A  Series may  also  enter into
contracts to sell foreign  currencies to protect against  a decline in value  of
its  foreign currency denominated  portfolio securities due to  a decline in the
value of foreign currencies against the  U.S. dollar. Contracts to sell  foreign
currency  could limit any potential gain which  might be realized by a Series if
the value of the hedged currency increased.
   A Series may also enter into forward foreign currency exchange contracts  for
non-hedging  purposes when the  investment adviser anticipates  that the foreign
currency will appreciate or depreciate  in value, but securities denominated  in
that  currency do  not present attractive  investment opportunities  and are not
held in the Series. A Series may  also engage in cross-hedging by using  forward
contracts  in  one  currency  to  hedge against  fluctuations  in  the  value of
securities denominated  in  a  different  currency  if  the  investment  adviser
believes that there is a pattern of correlation between the two currencies.
   If  a Series enters into a forward currency exchange contract to sell foreign
currency, it may be required to place cash or high grade liquid debt  securities
in  a segregated account  in an amount equal  to the value  of the Series' total
assets committed to  the consummation  of the forward  contract. Although  these
contracts can protect a Series from adverse exchange rates, they involve risk of
loss if N&B Management fails to predict foreign currency values correctly.
 
    PUT  AND CALL OPTIONS, FUTURES CONTRACTS,  OPTIONS ON FUTURES CONTRACTS (ALL
SERIES EXCEPT AMT  LIQUID ASSET INVESTMENTS).  Each of these  Series may try  to
reduce  the  risk of  securities  price changes  (hedge)  or generate  income by
writing (selling) covered call options against securities held in its  portfolio
having  a market value not exceeding 10% of its net assets and may purchase call
options in related closing transactions. The purchaser of a call option acquires
the right  to buy  a portfolio  security at  a fixed  price during  a  specified
period.  The maximum  price the  seller may realize  on the  security during the
option period is the  fixed price. The  seller continues to bear  the risk of  a
decline  in the security's price,  although this risk is  reduced by the premium
received for the option.
   AMT Limited Maturity Bond, Government  Income, and Balanced Investments  also
may  try to manage portfolio duration by (1) entering into interest-rate futures
contracts traded on futures exchanges and (2) purchasing and writing options  on
futures contracts.
   AMT  Limited Maturity Bond, Government  Income, and Balanced Investments also
may try to reduce the risk of  securities price changes and expected changes  in
prevailing  currency exchange rates  (hedge) and may  write covered call options
and purchase put options  on debt securities in  their portfolios or on  foreign
currencies  for hedging purposes or for the purpose of producing income. Each of
these Series will write call options on a security or currency only if it  holds
that security or currency or has the right to obtain the security or currency at
no  additional cost. These investment practices involve certain risks, including
transactional expense, price volatility and a high degree of leverage. A  Series
may  engage in  transactions in  futures contracts  and related  options only as
permitted by regulations of the Commodity Futures Trading Commission.
   AMT International Investments may enter  into futures contracts and  purchase
and  sell options on such  contracts on both the  U.S. and foreign exchanges for
hedging and non-hedging  purposes. AMT International  Investments may (1)  enter
into  futures contracts on debt  securities, interest rates, securities indices,
and currencies and (2) purchase and write options on futures contracts.
   AMT International Investments may purchase and write put and call options  on
foreign  currencies for the purpose of protecting against declines in the dollar
value of foreign portfolio securities and  against increases in the U.S.  dollar
cost  of foreign securities to  be acquired. The Series  may also use options on
foreign currencies to cross-hedge. In addition, the Series may purchase call  or
put  options on currencies for non-hedging  purposes when the investment adviser
expects that  the currency  will  appreciate or  depreciate  in value,  but  the
securities  denominated in  that currency  do not  present attractive investment
opportunities  and   are  not   held   in  the   Series.  Options   on   foreign
 
                                                                              37
<PAGE>
currencies  to be written or purchased by the  Series will be traded on U.S. and
foreign exchanges or over-the-counter. Options  on foreign currencies which  are
traded  in  the  over-the-counter  market  may  be  considered  to  be  illiquid
securities and subject to the restriction on illiquid securities. (See "Illiquid
Securities," above.)
   To realize  greater income  than would  be realized  on portfolio  securities
transactions alone, AMT International Investments may write call and put options
on  any securities  in which it  may invest  or options on  any securities index
based on securities in which the Series may invest. The Series will not write  a
call  option on a security or currency unless it owns the underlying security or
currency or has the right to obtain it at no additional cost.
   The writing and purchasing of options is a highly specialized activity  which
involves  investment techniques and  risks different from  those associated with
ordinary portfolio  securities  transactions  including  transactional  expense,
price  volatility and a  high degree of  leverage. AMT International Investments
pays  brokerage  commissions   or  spreads  in   connection  with  its   options
transactions,  as well  as for purchases  and sales of  underlying securities or
currency. The writing of  options could result in  significant increases in  the
Series' turnover rate.
   The  primary  risks in  using put  and call  options, futures  contracts, and
options on futures contracts, and forward foreign currency contracts or  options
on  foreign currencies ("Hedging Instruments")  are (1) imperfect correlation or
no correlation between  changes in market  value of the  securities held by  the
Series  and the prices of the Hedging Instruments; (2) possible lack of a liquid
secondary market for Hedging  Instruments and the  resulting inability to  close
out  a Hedging Instrument when  desired; (3) the fact  that the skills needed to
use Hedging Instruments are  different from those needed  to select the  Series'
securities;  (4) the  fact that, although  use of these  instruments for hedging
purposes can reduce the risk of loss,  they also can reduce the opportunity  for
gain,  or  even result  in losses,  by offsetting  favorable price  movements in
hedged investments; and (5) the possible inability of the Series to purchase  or
sell  a security at a time that would otherwise be favorable for it to do so, or
the possible need for the Series to  sell a security at a disadvantageous  time,
due  to its need  to maintain "cover"  or to segregate  securities in connection
with its use of these instruments. Futures, options and forward foreign currency
contracts are considered derivatives.
   
    FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES (ALL SERIES EXCEPT AMT LIQUID
ASSET INVESTMENTS). In a when-issued or forward commitment transaction, a Series
commits to purchase  securities in  order to  secure an  advantageous price  and
yield  at the time of  the commitment and pays for  the securities when they are
delivered at a future date (generally within three months). If the seller  fails
to  complete the sale, a  Series may lose the  opportunity to obtain a favorable
price and  yield. When-issued  securities  or securities  subject to  a  forward
commitment  may decline or increase in value  during the period from the Series'
investment commitment  to  the settlement  of  the purchase  which  may  magnify
fluctuation in the Series' NAV.
    
 
    INDEXED  SECURITIES  (AMT INTERNATIONAL,  LIMITED MATURITY  BOND, GOVERNMENT
INCOME AND BALANCED  INVESTMENTS). Each of  these Series may  invest in  indexed
securities  whose value  is linked  to currencies,  interest rates, commodities,
indices,  or   other  financial   indicators.   Most  indexed   securities   are
short-to-intermediate  term fixed-income securities whose  values at maturity or
interest rates rise or  fall according to  the change in  one or more  specified
underlying  instruments.  Indexed  securities may  be  positively  or negatively
indexed (i.e., their value may increase or decrease if the underlying instrument
appreciates), and may have return characteristics similar to direct  investments
in  the  underlying instrument  or  to one  or  more options  on  the underlying
instrument.  Indexed  securities  may  be  more  volatile  than  the  underlying
instrument itself.
 
    REPURCHASE  AGREEMENTS/SECURITIES LOANS (ALL SERIES).  Each Series may enter
into repurchase  agreements  and  lend  securities  from  its  portfolio.  In  a
repurchase  agreement, a  Series buys a  security from a  Federal Reserve member
bank (or with respect to AMT  International Investments, from a foreign bank  or
U.S.  branch  or  agency  of  a  foreign  bank),  or  a  securities  dealer  and
simultaneously agrees to sell it  back at a higher  price, at a specified  date,
usually less
than  a  week later.  The  underlying securities  must  fall within  the Series'
investment policies and limitations (but not
 
38
<PAGE>
limitations as to  maturity or duration).  Each Series also  may lend  portfolio
securities to banks, brokerage firms, or institutional investors to earn income.
Costs,  delays  or losses  could result  if  the selling  party to  a repurchase
agreement or the borrower of portfolio securities becomes bankrupt or  otherwise
defaults. N&B Management monitors the creditworthiness of sellers and borrowers.
 
    REVERSE  REPURCHASE AGREEMENTS  (ALL SERIES)  AND DOLLAR  ROLLS (AMT LIMITED
MATURITY BOND,  GOVERNMENT  INCOME,  AND BALANCED  INVESTMENTS).  In  a  reverse
repurchase  agreement, a Series sells securities  to a bank or securities dealer
and at the same time agrees to repurchase the same securities at a later date at
a fixed price. During the period before the repurchase, the Series continues  to
receive  principal and interest payments on the  securities. In a dollar roll, a
Series sells securities  for delivery  in the current  month and  simultaneously
contracts  to repurchase substantially similar (same type and coupon) securities
on a specified future  date from the  same party. During  the period before  the
repurchase,   the  Series  forgoes  principal   and  interest  payments  on  the
securities. The  Series is  compensated by  the difference  between the  current
sales  price and the forward price for the future purchase (often referred to as
the "drop"), as  well as  by the  interest earned on  the cash  proceeds of  the
initial  sale. Reverse repurchase  agreements and dollar  rolls may increase the
fluctuation in the market value of a  Series' assets and are forms of  leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements and dollar rolls.
 
   
    CONVERTIBLE SECURITIES (AMT  INTERNATIONAL, PARTNERS,  GROWTH, AND  BALANCED
INVESTMENTS).  Each  of these  Series may  invest  in convertible  securities. A
convertible security  is a  bond,  debenture, note,  preferred stock,  or  other
security  that may  be converted  into or exchanged  for a  prescribed amount of
common stock of the  same or a  different issuer within  a particular period  of
time  at a  specified price  or formula.  Many convertible  securities are rated
below investment grade, or are unrated.
    
 
    MORTGAGE-BACKED  SECURITIES  (AMT  LIQUID  ASSET,  LIMITED  MATURITY   BOND,
GOVERNMENT   INCOME,  AND  BALANCED   INVESTMENTS).  Mortgage-backed  securities
represent interests in, or  are secured by and  payable from, pools of  mortgage
loans,  including collateralized  mortgage obligations. These  securities may be
U.S. Government mortgage-backed securities, which are issued or guaranteed by  a
U.S.  Government agency or instrumentality (though not necessarily backed by the
full faith  and credit  of the  United States),  such as  GNMA, FNMA  and  FHLMC
certificates.  Other mortgage-backed  securities are issued  by private issuers,
generally originators  of and  investors in  mortgage loans,  including  savings
associations,  mortgage  bankers,  commercial  banks,  investment  bankers,  and
special purpose  entities.  These  private  mortgage-backed  securities  may  be
supported  by  U.S.  Government  mortgage-backed  securities  or  some  form  of
non-government credit enhancement.  Mortgage-backed securities  may have  either
fixed  or adjustable  interest rates.  Tax or  regulatory changes  may adversely
affect the  mortgage securities  market. In  addition, changes  in the  market's
perception of the issuer may affect the value of mortgage-backed securities. The
rate  of return on mortgage-backed securities  may be affected by prepayments of
principal on the underlying  loans, which generally  increase as interest  rates
decline;  as a result, when interest  rates decline, holders of these securities
normally do not benefit from appreciation in market value to the same extent  as
holders  of other  non-callable debt  securities. N&B  Management determines the
effective life  and duration  of mortgage-backed  securities based  on  industry
practice and current market conditions. If N&B Management's determination is not
borne out in practice, it could positively or negatively affect the value of the
Series  when  market interest  rates  change. Increasing  market  interest rates
generally extend the effective maturities of mortgage-backed securities.
 
    ASSET-BACKED SECURITIES (AMT LIQUID ASSET, LIMITED MATURITY BOND, GOVERNMENT
INCOME, AND BALANCED INVESTMENTS).  Asset-backed securities represent  interests
in,  or are secured by and payable from pools of assets, such as consumer loans,
CARS-SM- ("Certificates  for Automobile  Receivables"), credit  card  receivable
securities,  and installment  loan contracts.  Although these  securities may be
supported   by    letters   of    credit   or    other   credit    enhancements,
 
                                                                              39
<PAGE>
payment of interest and principal ultimately depends upon individuals paying the
underlying  loans. The  risk that  recovery on  repossessed collateral  might be
unavailable, or inadequate  to support  payments on  asset-backed securities  is
greater than in the case of mortgage-backed securities.
   
    OTHER    INVESTMENT   COMPANIES   (AMT   INTERNATIONAL   INVESTMENTS).   AMT
International Investments may invest up to 10% of its total assets, measured  at
the  time  of investment,  in  the shares  of  other investment  companies. Such
investment may be  the most practical  or only  manner in which  the Series  can
participate  in  certain foreign  markets because  of  the expenses  involved or
because vehicles for investing in certain countries may not be available at  the
time  the  Series  is  ready to  make  an  investment. As  a  shareholder  in an
investment company, the Series would bear its pro rata share of that  investment
company's  expenses. Investment in investment  companies may involve the payment
of substantial premiums above the  value of such issuers' portfolio  securities.
The  Series does not intend  to invest in such funds  unless, in the judgment of
the investment adviser, the  potential benefits of  such investment justify  the
payment of any applicable premium or sales charge.
    
 
    OTHER INVESTMENTS (AMT PARTNERS, GROWTH, AND BALANCED INVESTMENTS). Although
each  of these Series ordinarily invests  primarily in common stocks, except AMT
Balanced Investments (debt  portion), when  market conditions  warrant each  may
invest  in  preferred stocks,  securities convertible  into or  exchangeable for
common stocks,  U.S. Government  and Agency  Securities, investment  grade  debt
securities,  or money market instruments,  or may retain assets  in cash or cash
equivalents.
 
   
    SHORT  SELLING   (AMT   PARTNERS,  GROWTH,   BALANCED,   AND   INTERNATIONAL
INVESTMENTS).  Each Series  may attempt to  limit exposure to  a possible market
decline in the value of portfolio  securities through short sales of  securities
which the investment adviser believes possess volatility characteristics similar
to  those being hedged and may use short sales in an attempt to realize gain. To
effect such a transaction, a Series will borrow a security from a brokerage firm
to make  delivery to  the  buyer. A  Series then  is  obligated to  replace  the
security  borrowed  by  purchasing  it  at  the  market  price  at  the  time of
replacement. Until the security is replaced, a Series is required to pay to  the
lender any accrued interest or dividend and may be required to pay a premium.
    
   A  Series will realize a  gain if the security  declines in price between the
date of the short sale  and the date on which  the Series replaces the  borrowed
security.  A Series  will incur a  loss if  the price of  the security increases
between those dates. The amount of any gain will be decreased, and the amount of
any loss increased, by the amount of  any premium or interest the Series may  be
required  to pay in  connection with a  short sale. The  successful use of short
selling may be adversely affected by imperfect correlation between movements  in
the  price of  the security  sold short and  the securities  being hedged. Short
selling may defer recognition of gains or losses into another tax period.
   
   AMT Liquid  Asset,  Limited Maturity  Bond,  Partners, Growth,  Balanced  and
International  Investments may make short sales against-the-box. A short sale is
"against-the-box" when, at all times during which a short position is open,  the
Series owns an equal amount of such securities, or owns securities giving it the
right,  without payment  of future consideration,  to obtain an  equal amount of
securities sold short.
    
 
    SWAP AGREEMENTS (AMT  GOVERNMENT INCOME  INVESTMENTS). To  help enhance  the
value of its portfolio or manage its exposure to different types of investments,
the  Series may enter into interest rate, currency, and mortgage swap agreements
and may purchase and sell interest rate "caps," "floors," and "collars."
   In a typical interest rate swap  agreement, one party agrees to make  regular
payments  equal to a floating interest rate on a specified amount (the "notional
principal amount") in return for payments equal to a fixed interest rate on  the
same  amount for a specified period. If a swap agreement provides for payment in
different currencies,  the  parties may  also  agree to  exchange  the  notional
principal  amount. Mortgage  swap agreements are  similar to  interest rate swap
agreements, except the notional principal amount is tied to a reference pool  of
mortgages.
   In  a cap or  floor, one party agrees,  usually in return for  a fee, to make
payments under  particular  circumstances.  For example,  the  purchaser  of  an
interest  rate cap has the  right to receive payments  to the extent a specified
interest
 
40
<PAGE>
rate exceeds an agreed level;  the purchaser of an  interest rate floor has  the
right to receive payments to the extent a specified interest rate falls below an
agreed  level. A collar entitles the purchaser to receive payments to the extent
a specified interest rate falls outside an agreed range.
   Swap agreements, including caps and floors,  may involve leverage and may  be
highly  volatile; depending on how  they are used, they  may have a considerable
impact on the Series' performance. Swap agreements involve risks depending  upon
the  other  party's creditworthiness  and  ability to  perform,  as well  as the
Series' ability to terminate its swap agreements or reduce its exposure  through
offsetting  transactions. Swap  agreements may be  illiquid. The  swap market is
relatively new  and  is  largely  unregulated.  Swap  agreements  are  generally
considered "derivatives."
 
    VARIABLE  AND  FLOATING RATE  SECURITIES  (AMT BALANCED,  GOVERNMENT INCOME,
LIMITED MATURITY BOND AND LIQUID ASSET INVESTMENTS). Variable and floating  rate
securities  have interest rate adjustment formulas  that help to stabilize their
market value. Many of these instruments  carry a demand feature which permits  a
Series  to sell them during  a determined time period  at par value plus accrued
interest. The demand feature is often backed  by a credit instrument, such as  a
letter  of  credit, or  by a  creditworthy insurer.  A Series  may rely  on such
instrument or the creditworthiness  of the insurer in  purchasing a variable  or
floating  rate security. For purposes of determining its dollar-weighted average
maturity, AMT  Liquid Asset  Investments calculates  the remaining  maturity  of
variable  and floating rate instruments as provided  in Rule 2a-7 under the 1940
Act.
 
    ZERO COUPON  SECURITIES (ALL  SERIES).  Zero coupon  securities do  not  pay
interest  currently; instead, they are sold at  a discount from their face value
and are redeemed at face  value when they mature.  Because zero coupon bonds  do
not  pay current income, their  prices can be very  volatile when interest rates
change. In  calculating its  daily income,  a Series  accrues a  portion of  the
difference between a zero coupon bond's purchase price and its face value.
 
    MUNICIPAL  OBLIGATIONS (AMT LIMITED MATURITY BOND AND BALANCED INVESTMENTS).
Municipal obligations are  issued by  or on behalf  of states,  the District  of
Columbia, and U.S. territories and possessions and their political subdivisions,
agencies, and instrumentalities. The interest on municipal obligations is exempt
from  federal  income tax.  Municipal  obligations include  "general obligation"
securities, which are  backed by the  full taxing power  of a municipality,  and
"revenue"  securities, which are  backed by the income  from a specific project,
facility, or tax. Municipal obligations also include industrial development  and
private activity bonds -- the interest on which may be a tax preference item for
purposes  of the federal  alternative minimum tax  -- which are  issued by or on
behalf  of  public  authorities  and  are  not  backed  by  the  credit  of  any
governmental   or  public   authority.  "Anticipation   notes"  are   issued  by
municipalities in expectation of future proceeds from the issuance of bonds,  or
from  taxes or other revenues, and are  payable from those bond proceeds, taxes,
or revenues.  Municipal obligations  also include  tax-exempt commercial  paper,
which  is  issued  by  municipalities  to  help  finance  short-term  capital or
operating requirements. Current  efforts to restructure  the federal budget  and
the  relationship between the federal government and state and local governments
may impact the financing  of some issuers of  municipal securities. Some  states
and  localities are experiencing substantial deficits  and may find it difficult
for political or economic reasons to  increase taxes. Efforts are underway  that
may  result in  a "flat tax"  or other  restructuring of the  federal income tax
system. These developments could reduce  the value of all municipal  securities,
or the securities of particular issuers.
 
    RESTRICTED SECURITIES AND RULE 144A SECURITIES (ALL SERIES). Each Series may
invest  in restricted securities and Rule 144A securities. Restricted securities
cannot be sold to  the public without registration  under the Securities Act  of
1933 ("1933 Act"). Unless registered for sale, these securities can be sold only
in   privately  negotiated  transactions  or   pursuant  to  an  exemption  from
registration. Restricted securities are generally considered illiquid. Rule 144A
securities,  although  not   registered,  may  be   resold  only  to   qualified
institutional   buyers  in  accordance  with  Rule  144A  under  the  1933  Act.
Unregistered securities may also be sold  abroad pursuant to Regulation S  under
the  1933 Act. N&B Management, acting  pursuant to guidelines established by the
trustees of Managers Trust,  may determine that  some restricted securities  are
liquid.
 
                                                                              41

USE OF JOINT PROSPECTUS AND
STATEMENT OF ADDITIONAL INFORMATION
   Each  Portfolio and its  corresponding Series acknowledges  that it is solely
responsible for all information or lack of information about that Portfolio  and
Series  in this Prospectus  or in the SAI,  and no other  Portfolio or Series is
responsible therefor.  The trustees  of the  Trust and  of Managers  Trust  have
considered this factor in approving each Portfolio's and Series' use of a single
combined Prospectus and combined SAI.

ADVISERS MANAGEMENT TRUST
 
          Balanced Portfolio
 
- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of the Balanced Portfolio
are also offered directly to qualified pension and retirement plans  ("Qualified
Plans").
   THIS  PROSPECTUS CONTAINS  INFORMATION PERTAINING  TO THE  BALANCED PORTFOLIO
ONLY.
 
- --------------------------------------------------------------------------------
 
   
   EACH PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS  CORRESPONDING
SERIES  (EACH  A "SERIES")  OF ADVISERS  MANAGERS  TRUST ("MANAGERS  TRUST"), AN
OPEN-END MANAGEMENT INVESTMENT COMPANY.  AMT BALANCED INVESTMENTS, THE  BALANCED
PORTFOLIO'S  CORRESPONDING SERIES,  IS MANAGED  BY NEUBERGER&  BERMAN MANAGEMENT
INCORPORATED ("N&B MANAGEMENT"). AMT BALANCED INVESTMENTS INVESTS IN  SECURITIES
IN  ACCORDANCE WITH AN INVESTMENT OBJECTIVE, POLICIES, AND LIMITATIONS IDENTICAL
TO THOSE OF THE BALANCED PORTFOLIO.  THE INVESTMENT PERFORMANCE OF THE  BALANCED
PORTFOLIO  WILL  DIRECTLY  CORRESPOND  WITH THE  INVESTMENT  PERFORMANCE  OF AMT
BALANCED INVESTMENTS. THIS "MASTER/FEEDER FUND" STRUCTURE IS DIFFERENT FROM THAT
OF MANY OTHER INVESTMENT COMPANIES WHICH  DIRECTLY ACQUIRE AND MANAGE THEIR  OWN
PORTFOLIOS OF SECURITIES. FOR MORE INFORMATION ON THIS UNIQUE STRUCTURE THAT YOU
SHOULD    CONSIDER,   SEE    "SPECIAL   INFORMATION    REGARDING   ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS" ON PAGE 14.

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and limitations  that are  identical to  those of  the Portfolio.  The
trustees  of the  Trust believe  that this  "master/ feeder  fund" structure may
benefit shareholders.  For  more  information  about  the  organization  of  the
Portfolios  and the Series, including certain features of the master/feeder fund
structure, see "Special Information Regarding Organization, Capitalization,  and
Other  Matters" on page 14. For more details about AMT Balanced Investments, its
investments and their risks,  see "Investment Programs" on  page 8, "Ratings  of
Securities" on page 9, "Borrowings" on page 11, and "Description of Investments"
on page 24.
    
   Here  is a summary  of important features  of the Balanced  Portfolio and AMT
Balanced Investments. Of  course, there can  be no assurance  that the  Balanced
Portfolio will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An  investment in  any Portfolio involves  certain risks,  depending upon the
types of  investments made  by its  corresponding Series.  Special risk  factors
apply  to investments which may  be made by AMT  Balanced Investments in foreign
securities,  options  and  futures  contracts,  zero  coupon  bonds,  and   debt
securities  rated below  investment grade.  With respect  to the  portion of the
assets of AMT Balanced Investments which is invested in fixed income securities,
the value of which is  likely to decline in times  of rising interest rates  and
rise  in times of falling interest rates. In general, the longer the maturity of
a fixed  income security,  the more  pronounced is  the effect  of a  change  in
interest rates on the value of the security.
    
   
   AMT  Balanced Investments may invest up to 10% of the debt securities portion
of its investments, measured at the time of investment, in debt securities rated
below investment grade or comparable unrated securities. Securities rated  below
investment  grade  as well  as  unrated securities  are  often considered  to be
speculative and usually entail greater risk. For more information on lower-rated
securities, see "Ratings  of Securities"  in this Prospectus  and "Fixed  Income
Securities" in the SAI.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management,  with  the assistance  of  Neuberger&Berman  as sub-adviser,
selects investments for AMT Balanced  Investments. N&B Management also  provides
administrative  services to AMT Balanced  Investments and the Balanced Portfolio
and acts as  distributor of  the shares of  the Portfolio.  See "Management  and
Administration" in this Prospectus.
    
 
                                                                               3

          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   
   AMT  Balanced Investments (equity portion) is managed using a growth-oriented
investment approach.  This  approach seeks  out  stocks of  companies  that  are
projected  to grow at above-average rates and  may appear poised for a period of
accelerated earnings.
    
   
   The growth portfolio manager is  willing to pay a  higher share price in  the
hope  that the stock's earnings momentum will carry the stock's price higher. As
a stock's price increases based on  strong earnings, the stock's original  price
appears  low in  relation to  the growth  rate of  its earnings.  Sometimes this
happens when a particular company or  industry is temporarily out of favor  with
the  market or under-researched. This strategy is called "growth at a reasonable
price."
    
   
   In general,  AMT  Balanced  Investments  (equity  portion)  place  a  greater
emphasis  on finding securities  whose measures of fundamental  value are low in
relation to the growth rate of their future earnings and cash flow, as projected
by the  portfolio manager,  and  AMT Balanced  Investments (equity  portion)  is
therefore  willing to invest in securities  with prices that are somewhat higher
multiples of earnings.
    
   
   While this approach has resulted in  solid returns over the long term,  there
can  be no assurance that these results will be achieved in the future. For more
information, see "Performance Information" in this Prospectus.

7)Since  the  commencement  of operations,  N&B  Management  voluntarily assumed
  certain operating expenses of the Portfolio as described in Note B of Notes to
  Financial Statements and  in this Prospectus  under "Expense Limitation."  Had
  N&B  Management not undertaken such action,  the annualized ratios of expenses
  and net investment income  to average daily net  assets would have been  2.78%
  and 2.20%, respectively, for the period from February 28, 1989 to December 31,
  1989. There was no reduction of expenses for the years ended December 31, 1990
  through and including 1995.

8)The  Portfolio transferred all of its investment securities into its Series on
  April 28, 1995. After that date the Portfolio invested only in its Series  and
  that  Series, rather than  the Portfolio, engaged  in securities transactions.
  Therefore, after that date the Portfolio  had no portfolio turnover rate.  The
  portfolio  turnover  rate for  AMT Balanced  Investments from  May 1,  1995 to
  December 31, 1995 was 55%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in net asset value on  the performance of the  Portfolio during each year,  and
 assumes  dividends  and capital  gain distributions,  if any,  were reinvested.
 Results represent past performance and  do not guarantee future results.  Total
 return  figures  would have  been lower  if N&B  Management had  not reimbursed
 certain expenses. Investment  returns and  principal may  fluctuate and  shares
 when  redeemed may be worth  more or less than  original cost. The total return
 information shown does not reflect expenses that apply to the separate  account
 or  the related  insurance policies, and  the inclusion of  these charges would
 reduce the total return figures for  all years shown. Qualified Plans that  are
 direct shareholders of the Portfolio are not affected by insurance charges.

INVESTMENT PROGRAM
    
   
   The  investment policies  and limitations of  the Balanced  Portfolio and AMT
Balanced Investments are identical. The  Balanced Portfolio invests only in  AMT
Balanced Investments. Therefore, the following shows you the kinds of securities
in  which AMT Balanced Investments invests. For  an explanation of some types of
investments, see "Description of Investments" on page 24.
    
   Investment policies  and  limitations  of  the  Balanced  Portfolio  and  AMT
Balanced  Investments  are not  fundamental unless  otherwise specified  in this
Prospectus or  the SAI.  While a  non-fundamental policy  or limitation  may  be
changed  by the trustees of  the Trust or of  Managers Trust without shareholder
approval, the Balanced  Portfolio intends to  notify shareholders before  making
any  material change to  such policies or  limitations. Fundamental policies and
limitations may not  be changed without  shareholder approval. There  can be  no
assurance  that AMT Balanced Investments and the Balanced Portfolio will achieve
their objectives.  The  Balanced Portfolio,  by  itself, does  not  represent  a
comprehensive investment program.
   
   Additional  investment techniques,  features, and  limitations concerning AMT
Balanced Investments' investment program are described in the SAI.
    
 
          AMT Balanced Investments
 
- --------------------------------------------------------------------------------
 
   The investment  objective  of  AMT  Balanced  Investments  and  the  Balanced
Portfolio  is  long-term capital  growth and  reasonable current  income without
undue risk to principal. This investment objective is fundamental and may not be
changed without the  approval of the  holders of a  majority of the  outstanding
shares of the Portfolio and Series.
   
   N&B  Management  anticipates that  the Series'  investments will  normally be
managed so that approximately 60% of  the Series' total assets will be  invested
in  common stocks and the remaining assets  will be invested in debt securities.
However, depending on  N&B Management's views  regarding current market  trends,
the  common stock portion of the Series' investments may be adjusted downward to
as low as 50% or upward  to as high as 70%. At  least 25% of the Series'  assets
will be invested in fixed income securities.
    
   
   N&B  Management has analyzed the total return performance and volatility over
the last 36 years  of the Standard  & Poor's "500"  Composite Stock Price  Index
("S&P 500"), an unmanaged average widely considered as representative of general
stock  market performance. It has compared the performance and volatility of the
S&P "500" to  that of several  model balanced portfolios,  each consisting of  a
different  fixed  allocation of  the S&P  "500" and  U.S. Treasury  Notes having
maturities of 2 years. The comparison reveals that the model balanced  portfolio
in  which 60% was allocated  to the S&P "500" (with  the remaining 40% in 2-year
U.S. Treasury Notes) was  able to achieve  88.4% of the  performance of the  S&P
"500",  with only  63.5% of the  volatility. Those model  balanced portfolios in
which 70% and 50% were allocated to the S&P "500" were able to achieve 91.6% and
85.1%, respectively, of the  performance of the S&P  "500", with only 72.4%  and
54.9%  of the volatility,  respectively. While the  underlying securities in the
model balanced portfolios are  not identical to  the anticipated investments  by
AMT Balanced Investments and represent past performance, N&B Management believes
that  the results  of its  analysis show  the potential  benefits of  a balanced
investment approach. A chart  setting forth the study  appears as Appendix A  to
this Prospectus.
    
   
   In the common stock portion of its investments, AMT Balanced Investments will
invest  in a combination of common stocks  that N&B Management believes have the
maximum potential for long-term capital appreciation. This portion of the Series
does not seek to invest  in securities that pay  dividends or interest, and  any
such income is incidental. This portion of the Series expects to be almost fully
invested  in common stocks,  often of companies  that may be  temporarily out of
favor in the market.

<PAGE>
   
   The Series' aggressive growth investment program, with respect to its  equity
portion,  involves greater risks  and share price  volatility than programs that
invest in more conservative securities. Moreover,  the Series does not follow  a
policy  of active trading for short-term profits. Accordingly, the Series may be
more appropriate for investors with a longer-range perspective. The Series  uses
a  "growth  at  a reasonable  price"  investment approach.  When  N&B Management
believes that particular securities have greater potential for long-term capital
appreciation, the  Series may  purchase such  securities at  prices with  higher
multiples  to measures of  economic value (such  as earnings or  cash flow) than
other Series. In addition, the equity portion of the Series focuses on companies
with strong balance sheets  and reasonable valuations  relative to their  growth
rates. It also diversifies its investments into many companies and industries.
    
   
   In  the debt securities portion of  its investments, AMT Balanced Investments
will invest  in  a  diversified  portfolio  of  fixed  and  variable  rate  debt
securities and seeks to increase income and preserve and enhance total return by
actively  managing average portfolio duration in  light of market conditions and
trends. The  debt securities  portion of  the Series  invests in  a  diversified
portfolio  of short-to-intermediate-term  U.S. Government  and Agency securities
and debt securities issued by financial institutions, corporations, and  others,
primarily   investment  grade.  These  securities  include  mortgage-backed  and
asset-backed securities, repurchase agreements  with respect to U.S.  Government
and  Agency securities, and foreign investments. Up to 5% of the debt securities
portion of  the  Series  may  be  invested  in  municipal  securities  when  N&B
Management  believes such securities may  outperform other available issues. The
Series may purchase and sell covered call and put options, interest-rate futures
contracts, and options  on those  futures contracts  and may  engage in  lending
portfolio securities. The Series' dollar-weighted average portfolio duration may
range  up to four  years. AMT Balanced Investments  may invest up  to 10% of the
debt securities portion of its investments, measured at the time of  investment,
in  debt  securities  rated  below investment  grade  or  in  unrated securities
determined to be of  comparable quality by  N&B Management ("comparable  unrated
securities"). Debt securities rated below Baa by Moody's Investors Service, Inc.
("Moody's")  and  below  BBB by  Standard  &  Poor's Ratings  Group  ("S&P") are
considered to be below investment grade. Securities rated below investment grade
as well as comparable unrated securities are often considered to be  speculative
and  usually entail greater  risk. AMT Balanced Investments  will invest in debt
securities rated  no  lower than  B  by Moody's  or  S&P or  comparable  unrated
securities.  For more  information on  lower rated  securities, see  "Ratings of
Securities" in  this  Prospectus, "Fixed  Income  Securities" in  the  SAI,  and
Appendix A of the SAI.
    
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   Although  AMT  Balanced Investments  does  not purchase  securities  with the
intention of profiting from  short-term trading, the  Series may sell  portfolio
securities  prior to  maturity when  the investment  adviser believes  that such
action is advisable.
   
   The portfolio  turnover rates  for the  Balanced Portfolio  and AMT  Balanced
Investments,  and for the predecessor  of the Portfolio for  the period prior to
May 1, 1995, are set forth under "Financial Highlights" in this Prospectus.
    
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
   
    HIGH QUALITY DEBT  SECURITIES. High quality  debt securities are  securities
that  have received a rating from at least one nationally recognized statistical
rating organization ("NRSRO"), such as S&P or Moody's, in one of the two highest
rating categories (the highest category in the case of commercial paper) or,  if
not rated by any NRSRO, such as U.S. Government and Agency securities, have been
determined by N&B Management to be of comparable quality.
    
 
                                                                               9
<PAGE>
   
    INVESTMENT  GRADE DEBT  SECURITIES. "Investment  grade" debt  securities are
those receiving one of  the four highest ratings  from Moody's, S&P, or  another
NRSRO  or, if unrated by any NRSRO,  deemed comparable by N&B Management to such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's deems securities  rated in  its fourth  highest category  (Baa) to  have
speculative  characteristics;  a  change in  economic  factors could  lead  to a
weakened capacity of the issuer to repay.
    
   If the quality  of securities  held by the  Series deteriorates  so that  the
securities  would no longer satisfy its standards,  the Series will engage in an
orderly disposition  of the  downgraded securities  to the  extent necessary  to
ensure  that the Series' holdings  of such securities will  not exceed 5% of the
Series' net assets.
   
    LOWER-RATED SECURITIES. Debt securities rated  lower than Baa by Moody's  or
BBB  by S&P and  debt securities determined  to be of  comparable quality by N&B
Management  ("comparable  unrated  securities")  are  considered  to  be   below
investment  grade. AMT  Balanced Investments  may invest up  to 10%  of the debt
securities portion of its  investments, measured at the  time of investment,  in
debt  securities rated  below investment  grade, but  rated no  lower than  B by
Moody's or  S&P,  or  comparable  unrated  securities.  Securities  rated  below
investment  grade  ("junk bonds")  are  deemed by  Moody's  and S&P  (or foreign
statistical rating organizations) to  be predominantly speculative with  respect
to  the issuer's capacity to pay interest and repay principal in accordance with
the terms of the obligations.
    
   
   Those  debt  securities  in  the  lowest  rating  categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or  developments regarding the individual issuer  are more likely to cause price
volatility and weaken  the capacity of  the issuers of  such securities to  make
principal  and  interest  payments  than  is  the  case  for  higher  grade debt
securities. An economic downturn affecting the issuer may result in an increased
incidence of  default  and a  decline  in  prices of  the  issuer's  lower-rated
securities.  In the case of lower-rated  securities structured as zero-coupon or
pay-in-kind securities, their market prices are affected to a greater extent  by
interest  rate changes, and  therefore tend to be  more volatile than securities
that pay interest periodically and in cash.
    
   
   The market for lower-rated securities may be thinner and less active than for
higher-rated securities. The  secondary market  in which  debt securities  rated
below investment grade and comparable unrated securities are traded is generally
less  liquid than the market for higher grade debt securities. Less liquidity in
the secondary  trading market  could adversely  affect the  price at  which  the
Series  could sell a debt security rated below investment grade, or a comparable
unrated security, and could  adversely affect the daily  net asset value of  the
Series'  shares. At times of less liquidity, it may be more difficult to value a
debt security rated below  investment grade, or  a comparable unrated  security,
because  such valuation may require more  research, and elements of judgment may
play a greater role in the  valuation because there is less reliable,  objective
data  available.  N&B Management  will invest  in such  securities only  when it
concludes that the  anticipated return to  the Portfolio on  such an  investment
warrants  exposure to  the additional  level of  risk. A  further description of
Moody's and S&P's ratings is included in Appendix A to the SAI.
    
   
   The value of  the fixed  income securities in  which the  Series may  invest,
measured  in the currency in which they are denominated, is likely to decline in
times of rising interest  rates. Conversely, when rates  fall, the value of  the
Series'  fixed income investments  may rise. The longer  the period remaining to
maturity, the more  pronounced is  the effect of  interest rate  changes on  the
value of a security.

          Borrowings
 
- --------------------------------------------------------------------------------
 
   
   AMT  Balanced Investments  has a  fundamental policy  that it  may not borrow
money, except that it may (1) borrow money from banks for temporary or emergency
purposes and  not  for leveraging  or  investment  and (2)  enter  into  reverse
repurchase  agreements  for any  purpose,  so long  as  the aggregate  amount of
borrowings and reverse repurchase  agreements does not  exceed one-third of  the
Series'  total assets  (including the  amount borrowed)  less liabilities (other
than  borrowings).  The  Series   does  not  expect  to   borrow  money.  As   a
non-fundamental  policy, the Series may not purchase portfolio securities if its
outstanding borrowings, including  reverse repurchase agreements,  exceed 5%  of
its total assets. Dollar rolls are treated as reverse repurchase agreements.
    
   Currently,  the State of California imposes borrowing limitations on variable
insurance product funds.  To comply  with these  limitations, the  Series, as  a
matter of operating policy, has undertaken that it will not borrow more than 10%
of  its net  asset value  when borrowing  for any  general purpose  and will not
borrow more  than 25%  of its  net asset  value when  borrowing as  a  temporary
measure  to facilitate redemptions.  For these purposes, net  asset value is the
market value of all investments or assets owned less outstanding liabilities  at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   
   For  temporary defensive purposes, AMT Balanced  Investments may invest up to
100% of  its total  assets in  cash and  cash equivalents,  U.S. Government  and
Agency  Securities, commercial paper and certain other money market instruments,
as well  as repurchase  agreements collateralized  by the  foregoing. Also,  for
temporary  defensive purposes,  AMT Balanced  Investments (fixed  income portion
only) may adopt shorter weighted average duration than normal.
    
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.
 
   
          Duration
    
 
- --------------------------------------------------------------------------------
 
   
   Duration is a  measure of the  sensitivity of debt  securities to changes  in
market  interest  rates,  based on  the  entire  cash flow  associated  with the
securities,  including  payments  occurring   before  the  final  repayment   of
principal.  N&B Management  utilizes duration as  a tool  in portfolio selection
instead of the more traditional measure known as "term to maturity" in portfolio
selection for the debt securities portion of AMT Balanced Investments. "Term  to
maturity"  measures  only the  time  until a  debt  security provides  its final
payment, taking no account  of the pattern of  the security's payments prior  to
maturity.  Duration incorporates a bond's yield, coupon interest payments, final
maturity and call features into one measure. Duration therefore provides a  more
accurate  measurement of  a bond's  likely price change  in response  to a given
change in market interest rates. The longer the duration, the greater the bond's
price movement will be as interest  rates change. For any fixed income  security
with  interest payments occurring prior to the payment of principal, duration is
always less than maturity.
    
   
   Futures, options, and options on  futures have durations which are  generally
related  to the duration of the securities underlying them. Holding long futures
or call option positions will lengthen The Series' duration by approximately the
same amount as would holding an equivalent amount of the underlying  securities.
Short  futures  or put  options  have durations  roughly  equal to  the negative
duration of the securities that underlie these positions, and have the effect of
reducing portfolio duration by approximately the same amount as would selling an
equivalent amount of the underlying securities.
    
 
                                                                              11
<PAGE>
   
   There are some situations where  even the standard duration calculation  does
not  properly reflect  the interest  rate exposure  of a  security. For example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon reset. Another example where the  interest rate exposure is not  properly
captured by duration is the case of mortgage-backed securities. The stated final
maturity  of such securities is generally 30 years, but current prepayment rates
are critical in determining the securities' interest rate exposure. In these and
other similar  situations,  N&B  Management,  where  permitted,  will  use  more
sophisticated  analytical  techniques that  incorporate the  economic life  of a
security into the determination of its interest rate exposure.

PERFORMANCE INFORMATION
   Performance information for the Balanced Portfolio may be presented from time
to time  in advertisements  and  sales literature.  The Portfolio's  "yield"  is
calculated by dividing the Portfolio's annualized net investment income during a
recent  30-day period by the Portfolio's net asset  value on the last day of the
period. The Portfolio's  total return  is quoted  for the  one-year period,  the
five-year  period and  for the  life of  the Portfolio  through the  most recent
calendar quarter  and is  determined by  calculating the  change in  value of  a
hypothetical $1,000 investment in the Portfolio for each of those periods. Total
return   calculations  assume  reinvestment  of   all  Portfolio  dividends  and
distributions from net investment income and net realized gains, respectively.
   All performance information  presented for  the Portfolios is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life Company separate accounts investing in the Trust which
will take  into  account  insurance-related  charges  and  expenses  under  such
insurance  policies and contracts. Further information regarding the Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of the Portfolio to various indices. Advertisements may also contain
the performance rankings  assigned to the  Portfolio or its  adviser by  various
publications  and  statistical services.  Any such  comparisons or  rankings are
based  on  past  performance  and  the  statistical  computations  performed  by
publications  and  services,  and  are  not  necessarily  indications  of future
performance. Because the Portfolio is a managed investment vehicle investing  in
a  wide variety of  securities, the securities  owned by the  Portfolio will not
match those  making up  an index.  Please note  that indices  do not  take  into
account  any fees  and expenses of  investing in the  individual securities that
they track and that individuals cannot invest in any index.
 
                                                                              13

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  one Portfolio which as of December 31, 1995 had not yet commenced investment
operations.  These  conversions  were  approved  by  the  shareholders  of   the
predecessors of the Portfolios in August 1994. Each Portfolio invests all of its
net  investable assets  in its  corresponding Series,  in each  case receiving a
beneficial interest in  that Series.  The trustees  of the  Trust may  establish
additional   portfolios  or   classes  of   shares,  without   the  approval  of
shareholders. The assets of  each Portfolio belong only  to that Portfolio,  and
the  liabilities of  each Portfolio  are borne solely  by that  Portfolio and no
other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
   
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
    
   
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
    
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate Series. On May 1, 1995, each Portfolio (other than one Portfolio
which as  of December  31, 1995  had not  yet commenced  investment  operations)
invested all of its net investable assets (cash,
    
 
14
<PAGE>
   
securities, and receivables relating to securities) in a corresponding Series of
Managers  Trust, receiving a  beneficial interest in that  Series. The assets of
each Series belong only to that Series,  and the liabilities of each Series  are
borne solely by that Series and no other.
    
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor  in the  Series other  than a  Portfolio redeemed  its interest  in the
Series, the Series' remaining  investors (including the  Portfolio) might, as  a
result,  experience higher pro rata  operating expenses, thereby producing lower
returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a  Portfolio withdrew  its investment  from the  Series, the  trustees
would  consider what action might  be taken, including the  investment of all of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the Portfolio of its own investment  manager to manage its assets in  accordance
with  its investment objective, policies, and  limitations. The inability of the
Portfolio to find  a suitable  replacement could  have a  significant impact  on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors  except as required by the 1940  Act. Each investor in the Series will
be entitled to  vote in proportion  to its relative  beneficial interest in  the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act  and  other  applicable  law,  a Portfolio  will  solicit  proxies  from its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
                                                                              15
<PAGE>
Portfolio's shareholders. Pursuant to current  interpretations of the 1940  Act,
the  Life Companies  who are shareholders  of the Portfolio  will solicit voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be  liable  for all  obligations of  the Series,  but not  of the  other Series.
However, the  risk of  an investor  in the  Series incurring  financial loss  on
account  of such liability would be limited to circumstances in which the Series
had inadequate  insurance and  was unable  to meet  its obligations  out of  its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.

SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net  asset  value  ("NAV")  per  share. The  NAVs  for  each  Portfolio  and its
corresponding Series are calculated by subtracting liabilities from total assets
(in the case of the Series, the market value of the securities the Series  holds
plus  cash and other assets; in the case of a Portfolio, its percentage interest
in its  corresponding Series,  multiplied by  the Series'  NAV, plus  any  other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number  of Portfolio shares  outstanding and rounding the  result to the nearest
full cent.
   The Balanced Portfolio and AMT  Balanced Investments calculate their NAVs  as
of the close of regular trading on The New York Stock Exchange ("NYSE"), usually
4 p.m. Eastern time.
   AMT  Balanced  Investments  (debt securities  portion)  generally  values its
securities on the basis of bid  quotations from independent pricing services  or
principal  market makers, or, if quotations are  not available, by a method that
the trustees  of Managers  Trust  believe accurately  reflects fair  value.  The
Series  periodically  verifies  valuations  provided  by  the  pricing services.
Short-term securities with remaining maturities of less than 60 days are  valued
at cost which, when combined with interest earned, approximates market value.
   
   AMT  Balanced  Investments  (equity  portion)  values  its  equity securities
(including options)  listed on  the  NYSE, the  American Stock  Exchange,  other
national  exchanges, or the NASDAQ market, and other securities for which market
quotations are readily available,  at the latest  sale price on  the day NAV  is
calculated. If there is no sale of such a security on that day, that security is
valued  at  the mean  between its  closing  bid and  asked prices.  AMT Balanced
Investments  values  all  other  securities  and  assets,  including  restricted
securities,  by a method that the  trustees of Managers Trust believe accurately
reflects fair value.
    
 
                                                                              17

DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   
   The Balanced Portfolio annually distributes substantially all of its share of
AMT  Balanced  Investments'  net  investment  income  (net  of  the  Portfolio's
expenses),  net  realized capital  gains, and  net  realized gains  from foreign
currency transactions, if any, normally in February.
    
   
   The Balanced Portfolio  offers its shares  to separate accounts  of the  Life
Companies  and to  Qualified Plans.  All dividends  and other  distributions are
distributed to the  separate accounts  and to the  Qualified Plans  and will  be
automatically  invested in Trust shares.  Dividends and other distributions made
by a Portfolio to the  separate accounts are taxable, if  at all, to the  extent
described in the prospectuses for the Variable Contracts.
    
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   Each  Portfolio  is  treated as  a  separate  entity for  Federal  income tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment  company" under Subchapter M of the Internal Revenue Code of 1986, as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income, net short-term capital gain and net gains from certain foreign  currency
transactions)  and net  capital gain (the  excess of net  long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.  Each
Portfolio  intends  to  distribute  all  of its  net  income  and  gains  to its
shareholders each year.
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service that  each  Portfolio, as  an  investor  in a  corresponding  Series  of
Managers  Trust, will  be deemed  to own  a proportionate  share of  the Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will be treated as  a separate partnership for  Federal income tax purposes  and
will  not be a "publicly traded partnership," with the result that none of those
Series will  be subject  to  Federal income  tax  (and, instead,  each  investor
therein  will take into account in  determining its Federal income tax liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The foregoing is only a summary of  some of the important Federal income  tax
considerations  generally affecting  the Portfolios and  their shareholders; see
the SAI for a  more detailed discussion. Prospective  shareholders are urged  to
consult their tax advisers.

SPECIAL CONSIDERATIONS
    
   
   The  Portfolios serve  as the  underlying investments  for Variable Contracts
issued through separate accounts of the Life  Companies which may or may not  be
affiliated.   See  "Distribution  and  Redemption   of  Trust  Shares"  in  this
Prospectus.
    
   
   Section 817(h) of the Code  imposes certain diversification standards on  the
underlying  assets of segregated asset accounts  that fund contracts such as the
Variable Contracts (that is, the assets of the Series), which are in addition to
the diversification requirements imposed on the  Portfolios by the 1940 Act  and
Subchapter  M. Failure to satisfy those  standards would result in imposition of
Federal income tax on a Variable Contract owner with respect to the increase  in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset  account that funds contracts such as the Variable Contracts is treated as
meeting the  diversification standards  if, as  of the  close of  each  calendar
quarter,  the assets in the account  meet the diversification requirements for a
regulated investment company  and no more  than 55% of  those assets consist  of
cash,  cash items, U.S. Government securities  and securities of other regulated
investment companies.
    
   The Treasury Regulations amplify the  diversification standards set forth  in
Section  817(h) and  provide an  alternative to  the provision  described above.
Under the  regulations,  an  investment  portfolio  will  be  deemed  adequately
diversified  if (i) no  more than 55%  of the value  of the total  assets of the
portfolio is represented by any  one investment; (ii) no  more than 70% of  such
value  is represented  by any two  investments; (iii)  no more than  80% of such
value is represented by any three investments; and (iv) no more than 90% of such
value is represented by any four investments. For purposes of these  Regulations
all  securities of the same issuer are  treated as a single investment, but each
United States  government  agency  or  instrumentality shall  be  treated  as  a
separate issuer.
   
   Each  Series  will be  managed  with the  intention  of complying  with these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section 817  of the  Code  and the  Treasury  Regulations thereunder  do  not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder fund structure. As described  under "Tax Status" above, the  Trust
and  Managers Trust  have received  a ruling  from the  Internal Revenue Service
concluding that the "look-through" rule of  Section 817, which would permit  the
segregated  asset  accounts to  look  through to  the  underlying assets  of the
Series, will be available for the variable contract diversification test.
    
   Currently, the State  of California imposes  diversification requirements  on
variable  insurance products funds investing in non-U.S. securities. Under these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must be invested in at least five countries; less than 80% but at least 60%,  in
at  least four  countries; less  than 60% but  at least  40%, in  at least three
countries; and less than 40% but at least 20%, in at least two countries, except
that up to  35% of  a fund's  assets may be  invested in  securities of  issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United  Kingdom or Germany. The  Trust and Managers Trust  intend to comply with
the California diversification requirements, to the extent applicable.
 
                                                                              19

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B Management serves as the investment manager of AMT Balanced  Investments,
as  administrator of the Balanced Portfolio, and as distributor of the shares of
the  Balanced  Portfolio.  N&B  Management   and  its  predecessor  firms   have
specialized in the management of no-load mutual funds since 1950. In addition to
serving  the  Series  of  Managers Trust,  N&B  Management  currently  serves as
investment   manager   or   investment   adviser   of   other   mutual    funds.
Neuberger&Berman,  which acts  as sub-adviser  for the  Series and  other mutual
funds managed by  N&B Management,  also serves  as investment  adviser of  three
other   investment  companies.   These  funds   had  aggregate   net  assets  of
approximately $11.9 billion as of December 31, 1995.
    
   
   As sub-adviser,  Neuberger&Berman furnishes  N&B Management  with  investment
recommendations  and  research information  without  added cost  to  the Series.
Neuberger&Berman is a member firm of the NYSE and other principal exchanges  and
acts  as the  Series' principal  broker to the  extent a  broker is  used in the
purchase and sale of portfolio securities and the sale of covered call  options.
Neuberger&Berman and its affiliates, including N&B Management, manage securities
accounts that had approximately $38.7 billion of assets as of December 31, 1995.
All  of  the voting  stock of  N&B Management  is owned  by individuals  who are
general partners of Neuberger&Berman.
    
   
   Theresa A. Havell is a general partner of Neuberger&Berman and a director and
Vice President of N&B Management. Ms. Havell is the Manager of the Fixed  Income
Group of Neuberger&Berman, which she established in 1984. The Fixed Income Group
manages  fixed income accounts that had approximately $11.1 billion of assets as
of December  31,  1995.  Ms.  Havell has  had  overall  responsibility  for  the
activities of the Fixed Income Group since 1984.
    
   
   Thomas  G.  Wolfe and  Theresa A.  Havell are  primarily responsible  for the
day-to-day management of AMT Balanced Investments (debt securities portion). Mr.
Wolfe  has  been  primarily  responsible  for  AMT  Balanced  Investments  (debt
securities  portion) since October  1995. Mr. Wolfe has  been a Senior Portfolio
Manager in the  Fixed Income  Group since July  1993, Director  of Fixed  Income
Credit  Research since July 1993,  and a Vice President  of N&B Management since
October 1995. From  November 1987  to June  1993 he  was Vice  President in  the
Corporate Finance Department of Standard & Poor's Rating Group.
    
   
   Mark  R.  Goldstein  and  Susan Switzer  are  primarily  responsible  for the
day-to-day  management  of  AMT  Balanced  Investments  (equity  portion).   Mr.
Goldstein  is  a Vice  President  of N&B  Management  and a  general  partner of
Neuberger&Berman. He has had primary responsibility for AMT Balanced Investments
(equity portion) since April  1993. Previously he was  a securities analyst  and
portfolio    manager   with   that    firm.   Susan   Switzer    has   been   an
    
 
20
<PAGE>
   
Assistant Vice President  of N&B Management  since March 1995,  and a  portfolio
manager   for  Neuberger&Berman  since   January  1995.  She   has  had  primary
responsibility for AMT Balanced Investments (equity portion) since January 1995.
Ms. Switzer was a research analyst  and assistant portfolio manager for  another
money management firm from 1989 to 1994.
    
   
   N&B  Management serves as distributor in  connection with the offering of the
Balanced Portfolio's  shares. In  connection with  the sale  of the  Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information and  to  make  only  such  statements  and  representations  as  are
contained in the Portfolio's Prospectus. The distributor is responsible only for
information  given and  statements and  representations made  in the Portfolio's
Prospectus and is not responsible for any information given or any statements or
representations made by  the Life  Companies or  by brokers  or salespersons  in
connection with Variable Contracts.
    
   Neuberger&Berman acts as the principal broker for AMT Balanced Investments to
the extent a broker is used in the purchase and sale of portfolio securities and
in  the sale of covered call options,  and for those services receives brokerage
commissions. In  effecting  securities transactions,  AMT  Balanced  Investments
seeks  to obtain the best  price and execution of  orders. For more information,
see the SAI.
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate the  possibility that the  Series will be  adversely affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.

   The  Balanced Portfolio bears all expenses of its operations other than those
borne by N&B Management as administrator of the Portfolio and as distributor  of
its  shares. AMT Balanced Investments bears all expenses of its operations other
than those borne by  N&B Management as investment  manager of the Series.  These
expenses  include, but  are not  limited to, for  the Portfolio  and the Series,
legal and accounting fees and compensation  for trustees who are not  affiliated
with  N&B Management;  for the  Portfolio, transfer agent  fees and  the cost of
printing and sending reports  and proxy materials to  shareholders; and for  the
Series,  custodial  fees for  securities. Any  expenses  which are  not directly
attributable to a specific Series are allocated  on the basis of the net  assets
of the respective Series.
    
 
   
          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management has undertaken to limit  the Balanced Portfolio's expenses by
reimbursing the Portfolio for its operating  expenses and its pro rata share  of
AMT  Balanced Investments' operating expenses, excluding the compensation of N&B
Management, taxes, interest, extraordinary  expenses, brokerage commissions  and
transaction  costs, that  exceed 1% of  the Portfolio's average  daily net asset
value. This undertaking  is subject  to termination  on 60  days' prior  written
notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses  of the  Balanced Portfolio  and AMT  Balanced Investments  and thereby
increase total return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State Street Bank and Trust Company ("State Street"), Boston,  Massachusetts,
acts  as transfer and dividend paying agent for the Balanced Portfolio and in so
doing performs certain bookkeeping, data processing and administrative services.
All correspondence should be sent to State Street Bank & Trust Company, P.O. Box
1978, Boston, MA 02105. State Street  provides similar services to AMT  Balanced
Investments  as  the  Series' transfer  agent.  State  Street also  acts  as the
custodian of the Series' and the Portfolios' assets.

DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and payments under the  Variable Contracts issued  through separate accounts  of
the  Life Companies which may or may not be affiliated with the Trust. Shares of
the Balanced  Portfolio of  the Trust  are also  offered directly  to  Qualified
Plans. Shares of the Trust are purchased and redeemed at net asset value.
   The  Boards of Trustees  of the Trust  and Managers Trust  have undertaken to
monitor the Trust  and Managers Trust,  respectively, for the  existence of  any
material  irreconcilable conflict between the interests of the Variable Contract
owners of the Life  Companies and to  determine what action,  if any, should  be
taken  in the  event of a  conflict. The  Life Companies and  N&B Management are
responsible for reporting any potential or existing conflicts to the Boards. Due
to differences of tax  treatment and other  considerations, it is  theoretically
possible that the interests of various Variable Contract owners participating in
the  Trust and Managers Trust and the  interests of Qualified Plans investing in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or more Life  Company separate accounts  or Qualified Plans  might withdraw  its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions  will be  effected by the  separate accounts  to meet obligations
under the Variable Contracts and by the Qualified Plans. Contract owners do  not
deal  directly  with the  Trust  with respect  to  acquisition or  redemption of
shares. The trustees of the Trust may refuse to sell shares of any Portfolio  to
any  person, or suspend or terminate the  offering of shares of any Portfolio if
such action is required by law or by regulatory authorities having  jurisdiction
or  is, in the sole discretion of the trustees acting in good faith and in light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The Board of Trustees  of the Trust has  adopted a non-fee Distribution  Plan
for each Portfolio of the Trust.
   The  Distribution Plan recognizes that N&B  Management may use its assets and
resources, including its profits from  administration fees paid by a  Portfolio,
to  pay expenses associated with the  distribution of Portfolio shares. However,
N&B Management will  not receive  any separate fees  for such  expenses. To  the
extent  that any payments  made by a  Portfolio should be  deemed to be indirect
financing of any activity primarily intended to result in the sale of shares  of
the  Portfolio within the  context of Rule  12b-1 under the  1940 Act, then such
payments shall be deemed to be authorized by the Distribution Plan.
   Under the Distribution  Plan, the  Portfolio will require  N&B Management  to
provide  the Trust with quarterly reports  of the amounts expended in connection
with financing  any  activity  primarily  intended to  result  in  the  sale  of
Portfolio  shares,  and the  purpose for  which such  expenditure was  made. The
Distribution Plan may be terminated as to a particular Portfolio at any time  by
a  vote of a majority of the independent trustees of the Trust or by a vote of a
majority  of  the   outstanding  voting  securities   of  that  Portfolio.   The
Distribution  Plan does not require N&B  Management to perform any specific type
or level of distribution activities or  to incur any specific level of  expenses
for  activities  primarily intended  to  result in  the  sale of  shares  of the
Portfolio.
 
                                                                              23

DESCRIPTION OF INVESTMENTS
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Balanced Investments, as  indicated below, may  make the following  investments,
among  others,  individually  or in  combination,  although the  Series  may not
necessarily buy any or all of the types  of securities or use any or all of  the
investment  techniques that are  described. These investments  may be limited by
the requirements  with which  the Series  must  comply if  the Portfolio  is  to
qualify  as regulated investment companies for  tax purposes. The use of hedging
or other techniques is discretionary and no representation is made that the risk
of AMT Balanced Investments will be reduced by the techniques discussed in  this
section.  For additional information  on the following  investments and on other
types of investments the Series may make, see the SAI.
    
 
    U.S. GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities  are
obligations  of the  U.S.Treasury backed  by the  full faith  and credit  of the
United States. U.S.  Government Agency  securities are issued  or guaranteed  by
U.S.  Government agencies, instrumentalities, or other U.S. Government-sponsored
enterprises, such  as the  Government  National Mortgage  Association  ("GNMA"),
Federal  National  Mortgage  Association ("FNMA"),  Federal  Home  Loan Mortgage
Corporation ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee  Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may  be backed by the  full faith and credit of  the United States, the issuer's
ability to borrow from the U.S.  Treasury, subject to the Treasury's  discretion
in  certain cases,  or only  by the  credit of  the issuer.  U.S. Government and
Agency securities include certain mortgage-backed securities. The market  prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID  SECURITIES. The Series may  invest up to 10%  of its net assets in
securities that are illiquid, in that they cannot be expected to be sold  within
seven  days at  approximately the  price at  which they  are valued.  Due to the
absence of an  active trading market,  the Series may  experience difficulty  in
valuing  or  disposing of  illiquid  securities. N&B  Management  determines the
liquidity of  the  Series' securities,  under  supervision of  the  trustees  of
Managers Trust. Securities which are freely tradeable in their country of origin
or  in their principal market will not be considered illiquid securities even if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally outside the  U.S., including non-U.S.  governments, their  agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated in or indexed to foreign  currencies, which may also be affected  by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective of the  performance of  the underlying  investment. N&B  Management
considers  these  factors in  making investments  for  the Series.  AMT Balanced
Investments may  enter  into  forward  foreign  currency  contracts  or  futures
contracts (agreements to exchange one currency for another at a future date) and
related  options  to manage  currency risks  and  to facilitate  transactions in
foreign securities. Although these contracts can protect the Series from adverse
exchange rate changes, they involve  a risk of loss  if N&B Management fails  to
predict foreign currency values correctly.
   
   AMT  Balanced Investments  may invest  up to  10% of  the value  of its total
assets, measured  at the  time of  investment, in  foreign securities  that  are
issued  by non-United  States entities. The  10% limitation does  not apply with
respect to foreign securities  that are denominated  in U.S. dollars,  including
ADRs.  Foreign securities (including those denominated in U.S. dollars and ADRs)
are affected by political or economic developments in foreign countries.
    
   
   Investments in foreign securities could be affected by factors generally  not
thought  to be present in the U.S. Such factors include, but are not limited to,
varying custody, brokerage and settlement practices; difficulty in pricing  some
    
 
24
<PAGE>
   
foreign  securities; less public  information about issuers  of securities; less
governmental regulation and supervision over issuance and trading of securities;
the unavailability of  financial information or  the difficulty of  interpreting
financial   information  prepared  under   foreign  accounting  standards;  less
liquidity and more volatility in foreign securities markets; the possibility  of
expropriation; the imposition of foreign withholding and other taxes; political,
social,  or diplomatic  developments; limitations  on the  movement of  funds or
other assets of the Series between different countries; difficulties in invoking
legal process abroad and enforcing  contractual obligations; and the  difficulty
of  assessing  economic  trends  in  foreign  countries.  Investment  in foreign
securities also  involves  higher brokerage  and  custodian expenses  than  does
investment in domestic securities.
    
   In addition, investing in securities of foreign companies and governments may
involve  other  risks  which are  not  ordinarily associated  with  investing in
domestic securities. These risks include changes in currency exchange rates  and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions  applicable  to  such   investments  or  devaluations  of   foreign
currencies.  A decline in  the exchange rate  would reduce the  value of certain
portfolio  securities  irrespective  of   the  performance  of  the   underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and  changes in rates  of exchange with  the U.S. dollar  because the underlying
security is usually denominated in foreign currency. All of the foregoing  risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN  CURRENCY TRANSACTIONS.  The Series  may enter  into forward foreign
currency exchange  contracts in  order  to protect  against adverse  changes  in
future  foreign currency exchange  rates, to facilitate  transactions in foreign
securities and to  repatriate dividend  or interest income  received in  foreign
currencies.  The Series may enter into  contracts to purchase foreign currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends to purchase. The  Series may also enter  into contracts to sell  foreign
currencies  to  protect  against a  decline  in  value of  its  foreign currency
denominated portfolio  securities due  to  a decline  in  the value  of  foreign
currencies  against the  U.S. dollar. Contracts  to sell  foreign currency could
limit any potential gain which might be  realized by the Series if the value  of
the hedged currency increased.
   The  Series may also  enter into forward  foreign currency exchange contracts
for non-hedging  purposes  when  the investment  adviser  anticipates  that  the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated in that currency do not present attractive investment  opportunities
and  are not held in the Series. The  Series may also engage in cross-hedging by
using forward contracts  in one currency  to hedge against  fluctuations in  the
value  of  securities  denominated in  a  different currency  if  the investment
adviser believes  that  there  is  a pattern  of  correlation  between  the  two
currencies.
   If  the  Series enters  into  a forward  currency  exchange contract  to sell
foreign currency, it may  be required to  place cash or  high grade liquid  debt
securities  in  a segregated  account in  an amount  equal to  the value  of the
Series' total  assets committed  to the  consummation of  the forward  contract.
Although  these contracts  can protect the  Series from  adverse exchange rates,
they involve risk of  loss if N&B Management  fails to predict foreign  currency
values correctly.
 
    PUT  AND CALL OPTIONS, FUTURES CONTRACTS,  OPTIONS ON FUTURES CONTRACTS. The
Series may  try  to reduce  the  risk of  securities  price changes  (hedge)  or
generate  income by  writing (selling)  covered call  options against securities
held in its portfolio having a market value not exceeding 10% of its net  assets
and  may purchase call options in related closing transactions. The purchaser of
a call option acquires the  right to buy a portfolio  security at a fixed  price
during
 
                                                                              25
<PAGE>
a  specified period. The  maximum price the  seller may realize  on the security
during the option period is  the fixed price. The  seller continues to bear  the
risk  of a decline in the security's price, although this risk is reduced by the
premium received for the option.
   The Series also  may try to  manage portfolio duration  by (1) entering  into
interest-rate  futures contracts traded on  futures exchanges and (2) purchasing
and writing options on futures contracts.
   
   The Series also may try  to reduce the risk  of securities price changes  and
expected  changes in  prevailing currency exchange  rates (hedge)  and may write
covered call  options  and  purchase  put options  on  debt  securities  in  its
portfolio  or on foreign currencies  for hedging purposes or  for the purpose of
producing income. The Series will write  call options on a security or  currency
only  if it  holds that  security or  currency or  has the  right to  obtain the
security or currency at no  additional cost. These investment practices  involve
certain  risks,  including transactional  expense, price  volatility and  a high
degree of leverage. The Series may  engage in transactions in futures  contracts
and  related options only  as permitted by regulations  of the Commodity Futures
Trading Commission.
    
   The writing and purchasing of options is a highly specialized activity  which
involves  investment techniques and  risks different from  those associated with
ordinary portfolio  securities  transactions  including  transactional  expense,
price  volatility and a  high degree of  leverage. The writing  of options could
result in significant increases in the Series' turnover rate.
   The primary  risks in  using put  and call  options, futures  contracts,  and
options  on futures contracts, and forward foreign currency contracts or options
on foreign currencies ("Hedging Instruments")  are (1) imperfect correlation  or
no  correlation between changes  in market value  of the securities  held by the
Series and the prices of the Hedging Instruments; (2) possible lack of a  liquid
secondary  market for Hedging  Instruments and the  resulting inability to close
out a Hedging Instrument when  desired; (3) the fact  that the skills needed  to
use  Hedging Instruments are  different from those needed  to select the Series'
securities; (4) the  fact that, although  use of these  instruments for  hedging
purposes  can reduce the risk of loss,  they also can reduce the opportunity for
gain, or  even result  in losses,  by offsetting  favorable price  movements  in
hedged  investments; and (5) the possible inability of the Series to purchase or
sell a security at a time that would otherwise be favorable for it to do so,  or
the  possible need for the Series to  sell a security at a disadvantageous time,
due to its  need to maintain  "cover" or to  segregate securities in  connection
with its use of these instruments. Futures, options and forward foreign currency
contracts are considered derivatives.
 
    FORWARD  COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or forward
commitment transaction, the Series  commits to purchase  securities in order  to
secure  an advantageous price and  yield at the time  of the commitment and pays
for the securities when  they are delivered at  a future date (generally  within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity  to obtain  a favorable price  and yield.  When-issued securities or
securities subject to  a forward  commitment may  decline or  increase in  value
during  the period from  the Series' investment commitment  to the settlement of
the purchase which may magnify fluctuation in the Series' NAV.
 
    INDEXED SECURITIES. The Series may invest in indexed securities whose  value
is  linked  to  currencies,  interest  rates,  commodities,  indices,  or  other
financial indicators.  Most indexed  securities are  short-to-intermediate  term
fixed-income  securities whose values at maturity or interest rates rise or fall
according to the change in one or more specified underlying instruments. Indexed
securities may  be  positively or  negatively  indexed (i.e.,  their  value  may
increase  or decrease  if the underlying  instrument appreciates),  and may have
return  characteristics  similar  to   direct  investments  in  the   underlying
instrument  or  to one  or more  options on  the underlying  instrument. Indexed
securities may be more volatile than the underlying instrument itself.
 
26
<PAGE>
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements and lend securities  from its portfolio.  In a repurchase  agreement,
the  Series buys a security from a  Federal Reserve member bank, or a securities
dealer and  simultaneously agrees  to  sell it  back at  a  higher price,  at  a
specified  date, usually less than a  week later. The underlying securities must
fall within the Series' investment policies and limitations (but not limitations
as to maturity or  duration). The Series also  may lend portfolio securities  to
banks, brokerage firms, or institutional investors to earn income. Costs, delays
or  losses could result  if the selling  party to a  repurchase agreement or the
borrower of portfolio  securities becomes  bankrupt or  otherwise defaults.  N&B
Management monitors the creditworthiness of sellers and borrowers.
 
    REVERSE  REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.  In a  reverse repurchase
agreement, the Series sells securities to a bank or securities dealer and at the
same time agrees to repurchase  the same securities at a  later date at a  fixed
price.  During the period before the repurchase, the Series continues to receive
principal and interest payments on the securities. In a dollar roll, the  Series
sells  securities for delivery in the current month and simultaneously contracts
to repurchase  substantially similar  (same  type and  coupon) securities  on  a
specified  future  date  from  the  same party.  During  the  period  before the
repurchase,  the  Series  forgoes  principal   and  interest  payments  on   the
securities.  The Series  is compensated  by the  difference between  the current
sales price and the forward price for the future purchase (often referred to  as
the  "drop"), as  well as  by the interest  earned on  the cash  proceeds of the
initial sale. Reverse repurchase  agreements and dollar  rolls may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements and dollar rolls.
 
    CONVERTIBLE SECURITIES. The Series may  invest in convertible securities.  A
convertible  security  is a  bond, debenture,  note,  preferred stock,  or other
security that may  be converted  into or exchanged  for a  prescribed amount  of
common  stock of the  same or a  different issuer within  a particular period of
time at a  specified price  or formula.  Many convertible  securities are  rated
below investment grade, or, are unrated.
 
    MORTGAGE-BACKED  SECURITIES. Mortgage-backed  securities represent interests
in, or  are secured  by and  payable from,  pools of  mortgage loans,  including
collateralized  mortgage obligations.  These securities  may be  U.S. Government
mortgage-backed securities, which are issued or guaranteed by a U.S.  Government
agency  or instrumentality (though not necessarily  backed by the full faith and
credit of the United States), such  as GNMA, FNMA and FHLMC certificates.  Other
mortgage-backed  securities are issued by private issuers, generally originators
of and investors  in mortgage  loans, including  savings associations,  mortgage
bankers,  commercial banks,  investment bankers,  and special  purpose entities.
These private mortgage-backed  securities may  be supported  by U.S.  Government
mortgage-backed  securities or  some form of  non-government credit enhancement.
Mortgage-backed securities may have either  fixed or adjustable interest  rates.
Tax  or regulatory changes may adversely  affect the mortgage securities market.
In addition, changes  in the market's  perception of the  issuer may affect  the
value  of  mortgage-backed securities.  The  rate of  return  on mortgage-backed
securities may be affected by prepayments of principal on the underlying  loans,
which  generally increase as interest rates  decline; as a result, when interest
rates decline,  holders  of  these  securities  normally  do  not  benefit  from
appreciation in market value to the same extent as holders of other non-callable
debt  securities. N&B Management  determines the effective  life and duration of
mortgage-backed  securities  based  on  industry  practice  and  current  market
conditions.  If N&B Management's determination is  not borne out in practice, it
could positively  or negatively  affect  the value  of  the Series  when  market
interest  rates change.  Increasing market  interest rates  generally extend the
effective maturities of mortgage-backed securities.
 
                                                                              27
<PAGE>
    ASSET-BACKED SECURITIES. Asset-backed securities represent interests in,  or
are  secured  by and  payable  from pools  of  assets, such  as  consumer loans,
CARS-SM- ("Certificates  for Automobile  Receivables"), credit  card  receivable
securities,  and installment  loan contracts.  Although these  securities may be
supported by letters of credit or other credit enhancements, payment of interest
and principal ultimately depends upon  individuals paying the underlying  loans.
The  risk  that  recovery on  repossessed  collateral might  be  unavailable, or
inadequate to support payments on asset-backed securities is greater than in the
case of mortgage-backed securities.
 
    OTHER INVESTMENTS. When market conditions  warrant the Series may invest  in
preferred stocks, securities convertible into or exchangeable for common stocks,
U.S.  Government  and Agency  Securities, investment  grade debt  securities, or
money market instruments, or may retain assets in cash or cash equivalents.
 
    SHORT SELLING. The Series may attempt to limit exposure to a possible market
decline in the value of portfolio  securities through short sales of  securities
which the investment adviser believes possess volatility characteristics similar
to  those being hedged and may use short sales in an attempt to realize gain. To
effect such a transaction,  the Series will borrow  a security from a  brokerage
firm  to make delivery to the buyer. The Series then is obligated to replace the
security borrowed  by  purchasing  it  at  the  market  price  at  the  time  of
replacement.  Until the security is  replaced, the Series is  required to pay to
the lender  any accrued  interest  or dividend  and may  be  required to  pay  a
premium.
   The  Series will realize a gain if the security declines in price between the
date of the short sale  and the date on which  the Series replaces the  borrowed
security.  The Series will incur  a loss if the  price of the security increases
between those dates. The amount of any gain will be decreased, and the amount of
any loss increased, by the amount of  any premium or interest the Series may  be
required  to pay in  connection with a  short sale. The  successful use of short
selling may be adversely affected by imperfect correlation between movements  in
the  price of  the security  sold short and  the securities  being hedged. Short
selling may defer recognition of gains or losses into another tax period.
   
   AMT Balanced Investments may make  short sales against-the-box. A short  sale
is  "against-the-box" when, at all times during  which a short position is open,
the Series own an equal amount of  such securities, or own securities giving  it
the right, without payment of future consideration, to obtain an equal amount of
securities sold short.
    
 
    VARIABLE AND FLOATING RATE SECURITIES. Variable and floating rate securities
have  interest  rate adjustment  formulas that  help  to stabilize  their market
value. Many of these instruments carry a demand feature which permits the Series
to sell them during a determined time period at par value plus accrued interest.
The demand feature is often backed by  a credit instrument, such as a letter  of
credit,  or by a creditworthy insurer. The Series may rely on such instrument or
the creditworthiness of the  insurer in purchasing a  variable or floating  rate
security.
 
    ZERO   COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay  interest
currently; instead, they are sold  at a discount from  their face value and  are
redeemed  at face value when  they mature. Because zero  coupon bonds do not pay
current income, their prices can be very volatile when interest rates change. In
calculating its daily  income, the Series  accrues a portion  of the  difference
between a zero coupon bond's purchase price and its face value.
 
    MUNICIPAL  OBLIGATIONS. Municipal obligations are issued  by or on behalf of
states, the District of Columbia, and U.S. territories and possessions and their
political  subdivisions,  agencies,  and  instrumentalities.  The  interest   on
municipal  obligations is exempt from  federal income tax. Municipal obligations
include "general obligation"  securities, which  are backed by  the full  taxing
power  of  a municipality,  and "revenue"  securities, which  are backed  by the
income from a  specific project,  facility, or tax.  Municipal obligations  also
include  industrial development  and private activity  bonds --  the interest on
which may  be a  tax preference  item for  purposes of  the federal  alternative
minimum  tax -- which are  issued by or on behalf  of public authorities and are
not backed by the credit of any governmental or public authority.  "Anticipation
notes"  are issued by municipalities in  expectation of future proceeds from the
issuance
 
28
<PAGE>
of bonds, or  from taxes  or other  revenues, and  are payable  from those  bond
proceeds,  taxes,  or revenues.  Municipal  obligations also  include tax-exempt
commercial paper, which is issued  by municipalities to help finance  short-term
capital  or operating requirements.  Current efforts to  restructure the federal
budget and the relationship between the  federal government and state and  local
governments  may impact the  financing of some  issuers of municipal securities.
Some states and localities are experiencing substantial deficits and may find it
difficult for  political or  economic  reasons to  increase taxes.  Efforts  are
underway  that may result in a "flat  tax" or other restructuring of the federal
income tax system. These  developments could reduce the  value of all  municipal
securities, or the securities of particular issuers.
 
    RESTRICTED  SECURITIES AND  RULE 144A SECURITIES.  The Series  may invest in
restricted securities and Rule 144A securities. Restricted securities cannot  be
sold  to the public without registration under the Securities Act of 1933 ("1933
Act"). Unless  registered  for  sale,  these securities  can  be  sold  only  in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted  securities are generally considered  illiquid. Rule 144A securities,
although not registered, may be resold only to qualified institutional buyers in
accordance with Rule 144A under the  1933 Act. Unregistered securities may  also
be  sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.
 
                                                                              29

USE OF JOINT PROSPECTUS AND STATEMENT OF ADDITIONAL INFORMATION
   Each Portfolio and its  corresponding Series acknowledges  that it is  solely
responsible  for all information or lack of information about that Portfolio and
Series in the SAI, and no other Portfolio or Series is responsible therefor. The
trustees of  the Trust  and of  Managers Trust  have considered  this factor  in
approving each Portfolio's and Series' use of a single combined SAI.

ADVISERS MANAGEMENT TRUST
 
          Balanced Portfolio
 
- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of the Balanced Portfolio
are also offered directly to qualified pension and retirement plans  ("Qualified
Plans").
   THIS  PROSPECTUS CONTAINS  INFORMATION PERTAINING  TO THE  BALANCED PORTFOLIO
ONLY. THIS PROSPECTUS  IS USED IN  CONJUNCTION WITH  THE SALE OF  SHARES OF  THE
BALANCED PORTFOLIO TO QUALIFIED PLANS.

   EACH  PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS CORRESPONDING
SERIES (EACH  A "SERIES")  OF  ADVISERS MANAGERS  TRUST ("MANAGERS  TRUST"),  AN
OPEN-END  MANAGEMENT INVESTMENT COMPANY. AMT  BALANCED INVESTMENTS, THE BALANCED
PORTFOLIO'S CORRESPONDING  SERIES,  IS MANAGED  BY  NEUBERGER&BERMAN  MANAGEMENT
INCORPORATED  ("N&B MANAGEMENT"). AMT BALANCED INVESTMENTS INVESTS IN SECURITIES
IN ACCORDANCE WITH AN INVESTMENT OBJECTIVE, POLICIES, AND LIMITATIONS  IDENTICAL
TO  THOSE OF THE BALANCED PORTFOLIO.  THE INVESTMENT PERFORMANCE OF THE BALANCED
PORTFOLIO WILL  DIRECTLY  CORRESPOND  WITH THE  INVESTMENT  PERFORMANCE  OF  AMT
BALANCED INVESTMENTS. THIS "MASTER/FEEDER FUND" STRUCTURE IS DIFFERENT FROM THAT
OF  MANY OTHER INVESTMENT COMPANIES WHICH  DIRECTLY ACQUIRE AND MANAGE THEIR OWN
PORTFOLIOS OF SECURITIES. FOR MORE INFORMATION ON THIS UNIQUE STRUCTURE THAT YOU
SHOULD   CONSIDER,    SEE   "SPECIAL    INFORMATION   REGARDING    ORGANIZATION,

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and limitations  that are  identical to  those of  the Portfolio.  The
trustees  of  the Trust  believe that  this  "master/feeder fund"  structure may
benefit shareholders.  For  more  information  about  the  organization  of  the
Portfolios  and the Series, including certain features of the master/feeder fund
structure, see "Special Information Regarding Organization, Capitalization,  and
Other  Matters" on page 16. For more details about AMT Balanced Investments, its
investments and their risks,  see "Investment Program" on  page 10, "Ratings  of
Securities"   on  page  12,  "Borrowings"  on   page  13,  and  "Description  of
Investments" on page 26.
    
   Here is a  summary of important  features of the  Balanced Portfolio and  AMT
Balanced  Investments. Of  course, there can  be no assurance  that the Balanced
Portfolio will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An investment in  any Portfolio  involves certain risks,  depending upon  the
types  of investments  made by  its corresponding  Series. Special  risk factors
apply to investments which  may be made by  AMT Balanced Investments in  foreign
securities,   options  and  futures  contracts,  zero  coupon  bonds,  and  debt
securities rated below  investment grade.  With respect  to the  portion of  the
assets of AMT Balanced Investments which is invested in fixed income securities,
the  value of which is  likely to decline in times  of rising interest rates and
rise in times of falling interest rates. In general, the longer the maturity  of
a  fixed  income security,  the more  pronounced is  the effect  of a  change in
interest rates on the value of the security.
    
   
   AMT Balanced Investments may invest up to 10% of the debt securities  portion
of its investments, measured at the time of investment, in debt securities rated
below  investment grade or comparable unrated securities. Securities rated below
investment grade  as well  as  unrated securities  are  often considered  to  be
speculative and usually entail greater risk. For more information on lower-rated
securities,  see "Ratings  of Securities" in  this Prospectus  and "Fixed Income
Securities" in the SAI.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B Management,  with  the  assistance of  Neuberger&Berman  as  sub-adviser,
selects  investments for AMT Balanced  Investments. N&B Management also provides
administrative services to AMT Balanced  Investments and the Balanced  Portfolio
and  acts as  distributor of  the shares of  the Portfolio.  See "Management and
Administration" in this Prospectus.
    
 
                                                                               3

          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   
   AMT Balanced Investments (equity portion) is managed using a  growth-oriented
investment  approach.  This  approach seeks  out  stocks of  companies  that are
projected to grow at above-average rates and  may appear poised for a period  of
accelerated earnings.
    
   
   The  growth portfolio manager is  willing to pay a  higher share price in the
hope that the stock's earnings momentum will carry the stock's price higher.  As
a  stock's price increases based on  strong earnings, the stock's original price
appears low  in relation  to the  growth rate  of its  earnings. Sometimes  this
happens  when a particular company or industry  is temporarily out of favor with
the market or under-researched. This strategy is called "growth at a  reasonable
price."
    
   
   In  general,  AMT  Balanced  Investments  (equity  portion)  place  a greater
emphasis on finding securities  whose measures of fundamental  value are low  in
relation to the growth rate of their future earnings and cash flow, as projected
by  the  portfolio manager,  and AMT  Balanced  Investments (equity  portion) is
therefore willing to invest in securities  with prices that are somewhat  higher
multiples of earnings.
    
   
   While  this approach has resulted in solid  returns over the long term, there
can be no assurance that these results will be achieved in the future. For  more
information, see "Performance Information" in this Prospectus.

EXPENSE INFORMATION
   This section gives you certain information about the expenses of the Balanced
Portfolio  and AMT Balanced  Investments. See "Performance  Information" in this
Prospectus for important facts about the investment performance of the  Balanced
Portfolio, after taking expenses into account.

          Annual Portfolio Operating Expenses
          (AS PERCENTAGE OF AVERAGE DAILY NET ASSETS)
 
- --------------------------------------------------------------------------------
 
   
   The following tables shows annual  Total Operating Expenses for the  Balanced
Portfolio,  which are paid out of the assets of the Balanced Portfolio and which
include the  Portfolio's pro  rata  portion of  the  Operating Expenses  of  AMT
Balanced  Investments. These expenses are borne indirectly by Balanced Portfolio
shareholders. The Balanced Portfolio pays  N&B Management an administration  fee
based on the Portfolio's average daily net assets. AMT Balanced Investments pays
N&B Management a management fee based on the Series' average daily net assets; a
pro  rata portion  of this  fee is borne  indirectly by  the Balanced Portfolio.
Therefore, the table combines management and administration fees. The  Portfolio
and  Series also incur  other expenses for  things such as  accounting and legal
fees, maintaining shareholder records and furnishing shareholder statements  and
Portfolio  reports.  "Operating  Expenses"  exclude  interest,  taxes, brokerage
commissions, and extraordinary expenses.  The Portfolio's expenses are  factored
into  its share prices and  dividends and are not  charged directly to Portfolio
shareholders. For more information, see "Management and Administration" in  this
Prospectus and the SAI.

   Total   Operating  Expenses   for  the  Balanced   Portfolio  are  annualized
projections based  upon  current  administration  fees  for  the  Portfolio  and
management fees for AMT Balanced Investments, with "Other Expenses" based on the
Portfolio's  expenses for the  past fiscal year.  "Management and Administration
Fees" have been restated to reflect current expenses. The trustees of the  Trust
believe  that the aggregate per share expenses of the Balanced Portfolio and AMT
Balanced Investments will be approximately  equal to the expenses the  Portfolio
would incur if its assets were invested directly in the type of securities being
held  by AMT Balanced Investments.  The trustees of the  Trust also believe that
investment in AMT Balanced Investments by investors in addition to the  Balanced
Portfolio may enable
    
 
                                                                               5

AMT  Balanced  Investments  to achieve  economies  of scale  which  could reduce
expenses. The expenses  and, accordingly, the  returns of other  funds that  may
invest  in  AMT  Balance  Investments  may differ  from  those  of  the Balanced
Portfolio.
    
   To illustrate  the  effect  of  Operating Expenses,  let's  assume  that  the
Balanced  Portfolio's annual return is 5% and that it had annual Total Operating
Expenses described in  the table  above. For every  $1,000 you  invested in  the
Balanced  Portfolio, you would have paid the following amounts of total expenses
if you closed your account at the end of each of the following time periods:

   The assumption  in  this  example  of  a 5%  annual  return  is  required  by
regulations  of the Securities and Exchange  Commission applicable to all mutual
funds. The information in the table should not be considered a representation of
past or future expenses or  rates of return; actual  expenses or returns may  be
greater or less than those shown.

7)Since  the  commencement  of operations,  N&B  Management  voluntarily assumed
  certain operating expenses of the Portfolio as described in Note B of Notes to
  Financial Statements and  in this Prospectus  under "Expense Limitation."  Had
  N&B Management not undertaken such

<PAGE>
   
  action, the annualized ratios of expenses and net investment income to average
  daily net assets would have been 2.78% and 2.20%, respectively, for the period
  from  February  28, 1989  to  December 31,  1989.  There was  no  reduction of
  expenses for the years ended December 31, 1990 through and including 1995.
    
   
8)The Portfolio transferred all of its investment securities into its Series  on
  April  28, 1995. After that date the Portfolio invested only in its Series and
  that Series, rather  than the Portfolio,  engaged in securities  transactions.
  Therefore,  after that date the Portfolio  had no portfolio turnover rate. The
  portfolio turnover  rate for  AMT Balanced  Investments from  May 1,  1995  to
  December 31, 1995 was 55%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in  net asset value on  the performance of the  Portfolio during each year, and
 assumes dividends  and capital  gain distributions,  if any,  were  reinvested.
 Results  represent past performance and do  not guarantee future results. Total
 return figures  would have  been lower  if N&B  Management had  not  reimbursed
 certain  expenses. Investment  returns and  principal may  fluctuate and shares
 when redeemed may be worth  more or less than  original cost. The total  return
 information  shown does not reflect expenses that apply to the separate account
 or the related  insurance policies, and  the inclusion of  these charges  would
 reduce  the total return figures for all  years shown. Qualified Plans that are
 direct shareholders of the Portfolio are not affected by insurance charges.

INVESTMENT PROGRAM
    
   
   The  investment policies  and limitations of  the Balanced  Portfolio and AMT
Balanced Investments are identical. The  Balanced Portfolio invests only in  AMT
Balanced Investments. Therefore, the following shows you the kinds of securities
in  which AMT Balanced Investments invests. For  an explanation of some types of
investments, see "Description of Investments" on page 26.
    
   Investment policies  and  limitations  of  the  Balanced  Portfolio  and  AMT
Balanced  Investments  are not  fundamental unless  otherwise specified  in this
Prospectus or  the SAI.  While a  non-fundamental policy  or limitation  may  be
changed  by the trustees of  the Trust or of  Managers Trust without shareholder
approval, the Balanced  Portfolio intends to  notify shareholders before  making
any  material change to  such policies or  limitations. Fundamental policies and
limitations may not  be changed without  shareholder approval. There  can be  no
assurance  that AMT Balanced Investments and the Balanced Portfolio will achieve
their objectives.  The  Balanced Portfolio,  by  itself, does  not  represent  a
comprehensive investment program.
   
   Additional  investment techniques,  features, and  limitations concerning AMT
Balanced Investments' investment program are described in the SAI.
    
 
          AMT Balanced Investments
 
- --------------------------------------------------------------------------------
 
   The investment  objective  of  AMT  Balanced  Investments  and  the  Balanced
Portfolio  is  long-term capital  growth and  reasonable current  income without
undue risk to principal. This investment objective is fundamental and may not be
changed without the  approval of the  holders of a  majority of the  outstanding
shares of the Portfolio and Series.
   
   N&B  Management  anticipates that  the Series'  investments will  normally be
managed so that approximately 60% of  the Series' total assets will be  invested
in  common stocks and the remaining assets  will be invested in debt securities.
However, depending on  N&B Management's views  regarding current market  trends,
the  common stock portion of the Series' investments may be adjusted downward to
as low as 50% or upward  to as high as 70%. At  least 25% of the Series'  assets
will be invested in fixed income securities.
    
   
   N&B  Management has analyzed the total return performance and volatility over
the last 36 years  of the Standard  & Poor's "500"  Composite Stock Price  Index
("S&P 500"), an unmanaged average widely considered as representative of general
stock  market performance. It has compared the performance and volatility of the
S&P "500" to  that of several  model balanced portfolios,  each consisting of  a
different  fixed  allocation of  the S&P  "500" and  U.S. Treasury  Notes having
maturities of 2 years. The comparison reveals that the model balanced  portfolio
in  which 60% was allocated  to the S&P "500" (with  the remaining 40% in 2-year
U.S. Treasury Notes) was  able to achieve  88.4% of the  performance of the  S&P
"500",  with only  63.5% of the  volatility. Those model  balanced portfolios in
which 70% and 50% were allocated to the S&P "500" were able to achieve 91.6% and
85.1%, respectively, of the  performance of the S&P  "500", with only 72.4%  and
54.9%  of the volatility,  respectively. While the  underlying securities in the
model balanced portfolios are  not identical to  the anticipated investments  by
AMT Balanced Investments and represent past performance, N&B Management believes
that  the results  of its  analysis show  the potential  benefits of  a balanced
investment approach. A chart  setting forth the study  appears as Appendix A  to
this Prospectus.
    
   
   In the common stock portion of its investments, AMT Balanced Investments will
invest  in a combination of common stocks  that N&B Management believes have the
maximum potential for long-term capital appreciation. This portion of the Series
does not seek to invest  in securities that pay  dividends or interest, and  any
such income is incidental. This portion of the Series expects to be almost fully
invested  in common stocks,  often of companies  that may be  temporarily out of
favor in the market.
    
 
10
<PAGE>
   
   The Series' aggressive growth investment program, with respect to its  equity
portion,  involves greater risks  and share price  volatility than programs that
invest in more conservative securities. Moreover,  the Series does not follow  a
policy  of active trading for short-term profits. Accordingly, the Series may be
more appropriate for investors with a longer-range perspective. The Series  uses
a  "growth  at  a reasonable  price"  investment approach.  When  N&B Management
believes that particular securities have greater potential for long-term capital
appreciation, the  Series may  purchase such  securities at  prices with  higher
multiples  to measures of  economic value (such  as earnings or  cash flow) than
other Series. In addition, the equity portion of the Series focuses on companies
with strong balance sheets  and reasonable valuations  relative to their  growth
rates. It also diversifies its investments into many companies and industries.
    
   
   In  the debt securities portion of  its investments, AMT Balanced Investments
will invest  in  a  diversified  portfolio  of  fixed  and  variable  rate  debt
securities and seeks to increase income and preserve and enhance total return by
actively  managing average portfolio duration in  light of market conditions and
trends. The  debt securities  portion of  the Series  invests in  a  diversified
portfolio  of short-to-intermediate-term  U.S. Government  and Agency securities
and debt securities issued by financial institutions, corporations, and  others,
primarily   investment  grade.  These  securities  include  mortgage-backed  and
asset-backed securities, repurchase agreements  with respect to U.S.  Government
and  Agency securities, and foreign investments. Up to 5% of the debt securities
portion of  the  Series  may  be  invested  in  municipal  securities  when  N&B
Management  believes such securities may  outperform other available issues. The
Series may purchase and sell covered call and put options, interest-rate futures
contracts, and options  on those  futures contracts  and may  engage in  lending
portfolio securities. The Series' dollar-weighted average portfolio duration may
range  up to four  years. AMT Balanced Investments  may invest up  to 10% of the
debt securities portion of its investments, measured at the time of  investment,
in  debt  securities  rated  below investment  grade  or  in  unrated securities
determined to be of  comparable quality by  N&B Management ("comparable  unrated
securities"). Debt securities rated below Baa by Moody's Investors Service, Inc.
("Moody's")  and  below  BBB by  Standard  &  Poor's Ratings  Group  ("S&P") are
considered to be below investment grade. Securities rated below investment grade
as well as comparable unrated securities are often considered to be  speculative
and  usually entail greater  risk. AMT Balanced Investments  will invest in debt
securities rated  no  lower than  B  by Moody's  or  S&P or  comparable  unrated
securities.  For more  information on  lower rated  securities, see  "Ratings of
Securities" in  this  Prospectus, "Fixed  Income  Securities" in  the  SAI,  and
Appendix A of the SAI.
    
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   Although  AMT  Balanced Investments  does  not purchase  securities  with the
intention of profiting from  short-term trading, the  Series may sell  portfolio
securities  prior to  maturity when  the investment  adviser believes  that such
action is advisable.
   
   The portfolio  turnover rates  for the  Balanced Portfolio  and AMT  Balanced
Investments,  and for the predecessor  of the Portfolio for  the period prior to
May 1, 1995, are set forth under "Financial Highlights" in this Prospectus.
    
 
                                                                              11
<PAGE>
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
   
    HIGH QUALITY DEBT  SECURITIES. High quality  debt securities are  securities
that  have received a rating from at least one nationally recognized statistical
rating organization ("NRSRO"), such as S&P or Moody's, in one of the two highest
rating categories (the highest category in the case of commercial paper) or,  if
not rated by any NRSRO, such as U.S. Government and Agency securities, have been
determined by N&B Management to be of comparable quality.
    
 
   
    INVESTMENT  GRADE DEBT  SECURITIES. "Investment  grade" debt  securities are
those receiving one of  the four highest ratings  from Moody's, S&P, or  another
NRSRO  or, if unrated by any NRSRO,  deemed comparable by N&B Management to such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's deems securities  rated in  its fourth  highest category  (Baa) to  have
speculative  characteristics;  a  change in  economic  factors could  lead  to a
weakened capacity of the issuer to repay.
    
   If the quality  of securities  held by the  Series deteriorates  so that  the
securities  would no longer satisfy its standards,  the Series will engage in an
orderly disposition  of the  downgraded securities  to the  extent necessary  to
ensure  that the Series' holdings  of such securities will  not exceed 5% of the
Series' net assets.
   
    LOWER-RATED SECURITIES. Debt securities rated  lower than Baa by Moody's  or
BBB  by S&P and  debt securities determined  to be of  comparable quality by N&B
Management  ("comparable  unrated  securities")  are  considered  to  be   below
investment  grade. AMT  Balanced Investments  may invest up  to 10%  of the debt
securities portion of its  investments, measured at the  time of investment,  in
debt  securities rated  below investment  grade, but  rated no  lower than  B by
Moody's or  S&P,  or  comparable  unrated  securities.  Securities  rated  below
investment  grade  ("junk bonds")  are  deemed by  Moody's  and S&P  (or foreign
statistical rating organizations) to  be predominantly speculative with  respect
to  the issuer's capacity to pay interest and repay principal in accordance with
the terms of the obligations.
    
   
   Those  debt  securities  in  the  lowest  rating  categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or  developments regarding the individual issuer  are more likely to cause price
volatility and weaken  the capacity of  the issuers of  such securities to  make
principal  and  interest  payments  than  is  the  case  for  higher  grade debt
securities. An economic downturn affecting the issuer may result in an increased
incidence of  default  and a  decline  in  prices of  the  issuer's  lower-rated
securities.  In the case of lower-rated  securities structured as zero-coupon or
pay-in-kind securities, their market prices are affected to a greater extent  by
interest  rate changes, and  therefore tend to be  more volatile than securities
that pay interest periodically and in cash.
    
   
   The market for lower-rated securities may be thinner and less active than for
higher-rated securities. The  secondary market  in which  debt securities  rated
below investment grade and comparable unrated securities are traded is generally
less  liquid than the market for higher grade debt securities. Less liquidity in
the secondary  trading market  could adversely  affect the  price at  which  the
Series  could sell a debt security rated below investment grade, or a comparable
unrated security, and could  adversely affect the daily  net asset value of  the
Series'  shares. At times of less liquidity, it may be more difficult to value a
debt security rated below  investment grade, or  a comparable unrated  security,
because  such valuation may require more  research, and elements of judgment may
play a greater role in the  valuation because there is less reliable,  objective
data  available.  N&B Management  will invest  in such  securities only  when it
concludes that the  anticipated return to  the Portfolio on  such an  investment
warrants  exposure to  the additional  level of  risk. A  further description of
Moody's and S&P's ratings is included in Appendix A to the SAI.

<PAGE>
   
   The value of  the fixed  income securities in  which the  Series may  invest,
measured  in the currency in which they are denominated, is likely to decline in
times of rising interest  rates. Conversely, when rates  fall, the value of  the
Series'  fixed income investments  may rise. The longer  the period remaining to
maturity, the more  pronounced is  the effect of  interest rate  changes on  the
value of a security.
    
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   
   AMT  Balanced Investments  has a  fundamental policy  that it  may not borrow
money, except that it may (1) borrow money from banks for temporary or emergency
purposes and  not  for leveraging  or  investment  and (2)  enter  into  reverse
repurchase  agreements  for any  purpose,  so long  as  the aggregate  amount of
borrowings and reverse repurchase  agreements does not  exceed one-third of  the
Series'  total assets  (including the  amount borrowed)  less liabilities (other
than  borrowings).  The  Series   does  not  expect  to   borrow  money.  As   a
non-fundamental  policy, the Series may not purchase portfolio securities if its
outstanding borrowings, including  reverse repurchase agreements,  exceed 5%  of
its total assets. Dollar rolls are treated as reverse repurchase agreements.
    
   Currently,  the State of California imposes borrowing limitations on variable
insurance product funds.  To comply  with these  limitations, the  Series, as  a
matter of operating policy, has undertaken that it will not borrow more than 10%
of  its net  asset value  when borrowing  for any  general purpose  and will not
borrow more  than 25%  of its  net asset  value when  borrowing as  a  temporary
measure  to facilitate redemptions.  For these purposes, net  asset value is the
market value of all investments or assets owned less outstanding liabilities  at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   
   For  temporary defensive purposes, AMT Balanced  Investments may invest up to
100% of  its total  assets in  cash and  cash equivalents,  U.S. Government  and
Agency  Securities, commercial paper and certain other money market instruments,
as well  as repurchase  agreements collateralized  by the  foregoing. Also,  for
temporary  defensive purposes,  AMT Balanced  Investments (fixed  income portion
only) may adopt shorter weighted average duration than normal.
    
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.
 
   
          Duration
    
 
- --------------------------------------------------------------------------------
 
   
   Duration is a  measure of the  sensitivity of debt  securities to changes  in
market  interest  rates,  based on  the  entire  cash flow  associated  with the
securities,  including  payments  occurring   before  the  final  repayment   of
principal.  N&B Management  utilizes duration as  a tool  in portfolio selection
instead of the more traditional measure known as "term to maturity" in portfolio
selection for the debt securities portion of AMT Balanced Investments. "Term  to
maturity"  measures  only the  time  until a  debt  security provides  its final
payment, taking no account  of the pattern of  the security's payments prior  to
maturity.  Duration incorporates a bond's yield, coupon interest payments, final
maturity and call features into one measure. Duration therefore provides a  more
accurate  measurement of  a bond's  likely price change  in response  to a given
change in market interest rates. The longer the duration, the greater the bond's
price movement will be as interest  rates change. For any fixed income  security
with  interest payments occurring prior to the payment of principal, duration is
always less than maturity.
    
 
                                                                              13
<PAGE>
   
   Futures, options, and options on  futures have durations which are  generally
related  to the duration of the securities underlying them. Holding long futures
or call option positions will lengthen the Series' duration by approximately the
same amount as would holding an equivalent amount of the underlying  securities.
Short  futures  or put  options  have durations  roughly  equal to  the negative
duration of the securities that underlie these positions, and have the effect of
reducing portfolio duration by approximately the same amount as would selling an
equivalent amount of the underlying securities.
    
   
   There are some situations where  even the standard duration calculation  does
not  properly reflect  the interest  rate exposure  of a  security. For example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon reset. Another example where the  interest rate exposure is not  properly
captured by duration is the case of mortgage-backed securities. The stated final
maturity  of such securities is generally 30 years, but current prepayment rates
are critical in determining the securities' interest rate exposure. In these and
other similar  situations,  N&B  Management,  where  permitted,  will  use  more
sophisticated  analytical  techniques that  incorporate the  economic life  of a
security into the determination of its interest rate exposure.

PERFORMANCE INFORMATION
   Performance information for the Balanced Portfolio may be presented from time
to time  in advertisements  and  sales literature.  The Portfolio's  "yield"  is
calculated by dividing the Portfolio's annualized net investment income during a
recent  30-day period by the Portfolio's net asset  value on the last day of the
period. The Portfolio's  total return  is quoted  for the  one-year period,  the
five-year  period and  for the  life of  the Portfolio  through the  most recent
calendar quarter  and is  determined by  calculating the  change in  value of  a
hypothetical $1,000 investment in the Portfolio for each of those periods. Total
return   calculations  assume  reinvestment  of   all  Portfolio  dividends  and
distributions from net investment income and net realized gains, respectively.
   All performance information  presented for  the Portfolios is  based on  past
performance  and  does  not  predict  future  performance.  Further  information
regarding the Portfolio's performance is presented in the Trust's annual  report
to shareholders, which is available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of the Portfolio to various indices. Advertisements may also contain
the performance rankings  assigned to the  Portfolio or its  adviser by  various
publications  and  statistical services.  Any such  comparisons or  rankings are
based  on  past  performance  and  the  statistical  computations  performed  by
publications  and  services,  and  are  not  necessarily  indications  of future
performance. Because the Portfolio is a managed investment vehicle investing  in
a  wide variety of  securities, the securities  owned by the  Portfolio will not
match those  making up  an index.  Please note  that indices  do not  take  into
account  any fees  and expenses of  investing in the  individual securities that
they track and that individuals cannot invest in any index.
 
                                                                              15

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  one Portfolio which as of December 31, 1995 had not yet commenced investment
operations.  These  conversions  were  approved  by  the  shareholders  of   the
predecessors of the Portfolios in August 1994. Each Portfolio invests all of its
net  investable assets  in its  corresponding Series,  in each  case receiving a
beneficial interest in  that Series.  The trustees  of the  Trust may  establish
additional   portfolios  or   classes  of   shares,  without   the  approval  of
shareholders. The assets of  each Portfolio belong only  to that Portfolio,  and
the  liabilities of  each Portfolio  are borne solely  by that  Portfolio and no
other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate Series. On May 1, 1995, each Portfolio (other than one Portfolio
which as  of December  31, 1995  had not  yet commenced  investment  operations)
invested all of its net investable assets (cash,
    
 
16
<PAGE>
   
securities, and receivables relating to securities) in a corresponding Series of
Managers  Trust, receiving a  beneficial interest in that  Series. The assets of
each Series belong only to that Series,  and the liabilities of each Series  are
borne solely by that Series and no other.
    
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor  in the  Series other  than a  Portfolio redeemed  its interest  in the
Series, the Series' remaining  investors (including the  Portfolio) might, as  a
result,  experience higher pro rata  operating expenses, thereby producing lower
returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a  Portfolio withdrew  its investment  from the  Series, the  trustees
would  consider what action might  be taken, including the  investment of all of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the Portfolio of its own investment  manager to manage its assets in  accordance
with  its investment objective, policies, and  limitations. The inability of the
Portfolio to find  a suitable  replacement could  have a  significant impact  on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors  except as required by the 1940  Act. Each investor in the Series will
be entitled to  vote in proportion  to its relative  beneficial interest in  the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act  and  other  applicable  law,  a Portfolio  will  solicit  proxies  from its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
                                                                              17
<PAGE>
Portfolio's shareholders. Pursuant to current  interpretations of the 1940  Act,
the  Life Companies  who are shareholders  of the Portfolio  will solicit voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be  liable  for all  obligations of  the Series,  but not  of the  other Series.
However, the  risk of  an investor  in the  Series incurring  financial loss  on
account  of such liability would be limited to circumstances in which the Series
had inadequate  insurance and  was unable  to meet  its obligations  out of  its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.

<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net  asset  value  ("NAV")  per  share. The  NAVs  for  each  Portfolio  and its
corresponding Series are calculated by subtracting liabilities from total assets
(in the case of the Series, the market value of the securities the Series  holds
plus  cash and other assets; in the case of a Portfolio, its percentage interest
in its  corresponding Series,  multiplied by  the Series'  NAV, plus  any  other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number  of Portfolio shares  outstanding and rounding the  result to the nearest
full cent.
   The Balanced Portfolio and AMT  Balanced Investments calculate their NAVs  as
of the close of regular trading on The New York Stock Exchange ("NYSE"), usually
4 p.m. Eastern time.
   AMT  Balanced  Investments  (debt securities  portion)  generally  values its
securities on the basis of bid  quotations from independent pricing services  or
principal  market makers, or, if quotations are  not available, by a method that
the trustees  of Managers  Trust  believe accurately  reflects fair  value.  The
Series  periodically  verifies  valuations  provided  by  the  pricing services.
Short-term securities with remaining maturities of less than 60 days are  valued
at cost which, when combined with interest earned, approximates market value.
   
   AMT  Balanced  Investments  (equity  portion)  values  its  equity securities
(including options)  listed on  the  NYSE, the  American Stock  Exchange,  other
national  exchanges, or the NASDAQ market, and other securities for which market
quotations are readily available,  at the latest  sale price on  the day NAV  is
calculated. If there is no sale of such a security on that day, that security is
valued  at  the mean  between its  closing  bid and  asked prices.  AMT Balanced
Investments  values  all  other  securities  and  assets,  including  restricted
securities,  by a method that the  trustees of Managers Trust believe accurately
reflects fair value.
    
 
                                                                              19

DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   The Balanced Portfolio annually distributes substantially all of its share of
AMT  Balanced  Investments'  net  investment  income  (net  of  the  Portfolio's
expenses),  net  realized capital  gains, and  net  realized gains  from foreign
currency transactions, if any, normally in February.
   
   The Balanced Portfolio  offers its shares  to separate accounts  of the  Life
Companies  and to  Qualified Plans.  All dividends  and other  distributions are
distributed to the  separate accounts  and to the  Qualified Plans  and will  be
automatically  invested in Trust shares.  Dividends and other distributions made
by a Portfolio to the  separate accounts are taxable, if  at all, to the  extent
described in the prospectuses for the Variable Contracts.
    
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   Each  Portfolio  is  treated as  a  separate  entity for  Federal  income tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment  company" under Subchapter M of the Internal Revenue Code of 1986, as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income, net short-term capital gain and net gains from certain foreign  currency
transactions)  and net  capital gain (the  excess of net  long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.  Each
Portfolio  intends  to  distribute  all  of its  net  income  and  gains  to its
shareholders each year.
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service that  each  Portfolio, as  an  investor  in a  corresponding  Series  of
Managers  Trust, will  be deemed  to own  a proportionate  share of  the Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will be treated as  a separate partnership for  Federal income tax purposes  and
will  not be a "publicly traded partnership," with the result that none of those
Series will  be subject  to  Federal income  tax  (and, instead,  each  investor
therein  will take into account in  determining its Federal income tax liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The foregoing is only a summary of  some of the important Federal income  tax
considerations  generally affecting  the Portfolios and  their shareholders; see
the SAI for a  more detailed discussion. Prospective  shareholders are urged  to
consult their tax advisers.

SPECIAL CONSIDERATIONS
   
   The  Portfolios serve  as the  underlying investments  for Variable Contracts
issued through separate accounts of the Life  Companies which may or may not  be
affiliated.   See  "Distribution  and  Redemption   of  Trust  Shares"  in  this
Prospectus.
    
   
   Section 817(h) of the Code  imposes certain diversification standards on  the
underlying  assets of segregated asset accounts  that fund contracts such as the
Variable Contracts (that is, the assets of the Series), which are in addition to
the diversification requirements imposed on the  Portfolios by the 1940 Act  and
Subchapter  M. Failure to satisfy those  standards would result in imposition of
Federal income tax on a Variable Contract owner with respect to the increase  in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset  account that funds contracts such as the Variable Contracts is treated as
meeting the  diversification standards  if, as  of the  close of  each  calendar
quarter,  the assets in the account  meet the diversification requirements for a
regulated investment company  and no more  than 55% of  those assets consist  of
cash,  cash items, U.S. Government securities  and securities of other regulated
investment companies.
    
   The Treasury Regulations amplify the  diversification standards set forth  in
Section  817(h) and  provide an  alternative to  the provision  described above.
Under the  regulations,  an  investment  portfolio  will  be  deemed  adequately
diversified  if (i) no  more than 55%  of the value  of the total  assets of the
portfolio is represented by any  one investment; (ii) no  more than 70% of  such
value  is represented  by any two  investments; (iii)  no more than  80% of such
value is represented by any three investments; and (iv) no more than 90% of such
value is represented by any four investments. For purposes of these  Regulations
all  securities of the same issuer are  treated as a single investment, but each
United States  government  agency  or  instrumentality shall  be  treated  as  a
separate issuer.
   
   Each  Series  will be  managed  with the  intention  of complying  with these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section 817  of the  Code  and the  Treasury  Regulations thereunder  do  not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder fund structure. As described  under "Tax Status" above, the  Trust
and  Managers Trust  have received  a ruling  from the  Internal Revenue Service
concluding that the "look-through" rule of  Section 817, which would permit  the
segregated  asset  accounts to  look  through to  the  underlying assets  of the
Series, will be available for the variable contract diversification test.
    
   Currently, the State  of California imposes  diversification requirements  on
variable  insurance products funds investing in non-U.S. securities. Under these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must be invested in at least five countries; less than 80% but at least 60%,  in
at  least four  countries; less  than 60% but  at least  40%, in  at least three
countries; and less than 40% but at least 20%, in at least two countries, except
that up to  35% of  a fund's  assets may be  invested in  securities of  issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United  Kingdom or Germany. The  Trust and Managers Trust  intend to comply with
the California diversification requirements, to the extent applicable.
 
                                                                              21

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B Management serves as the investment manager of AMT Balanced  Investments,
as  administrator of the Balanced Portfolio, and as distributor of the shares of
the  Balanced  Portfolio.  N&B  Management   and  its  predecessor  firms   have
specialized in the management of no-load mutual funds since 1950. In addition to
serving  the  Series  of  Managers Trust,  N&B  Management  currently  serves as
investment   manager   or   investment   adviser   of   other   mutual    funds.
Neuberger&Berman,  which acts  as sub-adviser  for the  Series and  other mutual
funds managed by  N&B Management,  also serves  as investment  adviser of  three
other   investment  companies.   These  funds   had  aggregate   net  assets  of
approximately $11.9 billion as of December 31, 1995.
    
   
   As sub-adviser,  Neuberger&Berman furnishes  N&B Management  with  investment
recommendations  and  research information  without  added cost  to  the Series.
Neuberger&Berman is a member firm of the NYSE and other principal exchanges  and
acts  as the  Series' principal  broker to the  extent a  broker is  used in the
purchase and sale of portfolio securities and the sale of covered call  options.
Neuberger&Berman and its affiliates, including N&B Management, manage securities
accounts that had approximately $38.7 billion of assets as of December 31, 1995.
All  of  the voting  stock of  N&B Management  is owned  by individuals  who are
general partners of Neuberger&Berman.
    
   
   Theresa A. Havell is a general partner of Neuberger&Berman and a director and
Vice President of N&B Management. Ms. Havell is the Manager of the Fixed  Income
Group of Neuberger&Berman, which she established in 1984. The Fixed Income Group
manages  fixed income accounts that had approximately $11.1 billion of assets as
of December  31,  1995.  Ms.  Havell has  had  overall  responsibility  for  the
activities of the Fixed Income Group since 1984.
    
   
   Thomas  G.  Wolfe and  Theresa A.  Havell are  primarily responsible  for the
day-to-day management of AMT Balanced Investments (debt securities portion). Mr.
Wolfe  has  been  primarily  responsible  for  AMT  Balanced  Investments  (debt
securities  portion) since October  1995. Mr. Wolfe has  been a Senior Portfolio
Manager in the  Fixed Income  Group since July  1993, Director  of Fixed  Income
Credit  Research since July 1993,  and a Vice President  of N&B Management since
October 1995. From  November 1987  to June  1993 he  was Vice  President in  the
Corporate Finance Department of Standard & Poor's Rating Group.
    
   
   Mark  R.  Goldstein  and  Susan Switzer  are  primarily  responsible  for the
day-to-day  management  of  AMT  Balanced  Investments  (equity  portion).   Mr.
Goldstein  is  a Vice  President  of N&B  Management  and a  general  partner of
Neuberger&Berman. He has had primary responsibility for AMT Balanced Investments
(equity portion) since April  1993. Previously he was  a securities analyst  and
portfolio    manager   with   that    firm.   Susan   Switzer    has   been   an
    
 
22
<PAGE>
   
Assistant Vice President  of N&B Management  since March 1995,  and a  portfolio
manager   for  Neuberger&Berman  since   January  1995.  She   has  had  primary
responsibility for AMT Balanced Investments (equity portion) since January 1995.
Ms. Switzer was a research analyst  and assistant portfolio manager for  another
money management firm from 1989 to 1994.
    
   N&B  Management serves as distributor in  connection with the offering of the
Balanced Portfolio's  shares. In  connection with  the sale  of the  Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information and  to  make  only  such  statements  and  representations  as  are
contained in the Portfolio's Prospectus. The distributor is responsible only for
information  given and  statements and  representations made  in the Portfolio's
Prospectus and is not responsible for any information given or any statements or
representations made by  the Life  Companies or  by brokers  or salespersons  in
connection with Variable Contracts.
   Neuberger&Berman acts as the principal broker for AMT Balanced Investments to
the extent a broker is used in the purchase and sale of portfolio securities and
in  the sale of covered call options,  and for those services receives brokerage
commissions. In  effecting  securities transactions,  AMT  Balanced  Investments
seeks  to obtain the best  price and execution of  orders. For more information,
see the SAI.
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate the  possibility that the  Series will be  adversely affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.

   The  Balanced Portfolio bears all expenses of its operations other than those
borne by N&B Management as administrator of the Portfolio and as distributor  of
its  shares. AMT Balanced Investments bears all expenses of its operations other
than those borne by  N&B Management as investment  manager of the Series.  These
expenses  include, but  are not  limited to, for  the Portfolio  and the Series,
legal and accounting fees and compensation  for trustees who are not  affiliated
with  N&B Management;  for the  Portfolio, transfer agent  fees and  the cost of
printing and sending reports  and proxy materials to  shareholders; and for  the
Series,  custodial  fees for  securities. Any  expenses  which are  not directly
attributable to a specific Series are allocated  on the basis of the net  assets
of the respective Series.
    
 
          Expense Limitation
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management has undertaken to limit  the Balanced Portfolio's expenses by
reimbursing the Portfolio for its operating  expenses and its pro rata share  of
AMT  Balanced Investments' operating expenses, excluding the compensation of N&B
Management, taxes, interest, extraordinary  expenses, brokerage commissions  and
transaction  costs, that  exceed 1% of  the Portfolio's average  daily net asset
value. This undertaking  is subject  to termination  on 60  days' prior  written
notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses  of the  Balanced Portfolio  and AMT  Balanced Investments  and thereby
increase total return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State Street Bank and Trust Company ("State Street"), Boston,  Massachusetts,
acts  as transfer and dividend paying agent for the Balanced Portfolio and in so
doing performs certain bookkeeping, data processing and administrative services.
All correspondence should be sent to State Street Bank & Trust Company, care  of
Boston  Service, P.O.  Box 8403,  Boston, MA  02266-8403. State  Street provides
similar services  to AMT  Balanced Investments  as the  Series' transfer  agent.
State  Street also  acts as  the custodian  of the  Series' and  the Portfolios'
assets.

DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and payments under the  Variable Contracts issued  through separate accounts  of
the  Life Companies which may or may not be affiliated with the Trust. Shares of
the Balanced  Portfolio of  the Trust  are also  offered directly  to  Qualified
Plans. Shares of the Trust are purchased and redeemed at net asset value.
   The  Boards of Trustees  of the Trust  and Managers Trust  have undertaken to
monitor the Trust  and Managers Trust,  respectively, for the  existence of  any
material  irreconcilable conflict between the interests of the Variable Contract
owners of the Life  Companies and to  determine what action,  if any, should  be
taken  in the  event of a  conflict. The  Life Companies and  N&B Management are
responsible for reporting any potential or existing conflicts to the Boards. Due
to differences of tax  treatment and other  considerations, it is  theoretically
possible that the interests of various Variable Contract owners participating in
the  Trust and Managers Trust and the  interests of Qualified Plans investing in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or more Life  Company separate accounts  or Qualified Plans  might withdraw  its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions  will be  effected by the  separate accounts  to meet obligations
under the Variable Contracts and by the Qualified Plans. Contract owners do  not
deal  directly  with the  Trust  with respect  to  acquisition or  redemption of
shares. The trustees of the Trust may refuse to sell shares of any Portfolio  to
any  person, or suspend or terminate the  offering of shares of any Portfolio if
such action is required by law or by regulatory authorities having  jurisdiction
or  is, in the sole discretion of the trustees acting in good faith and in light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The Board of Trustees  of the Trust has  adopted a non-fee Distribution  Plan
for each Portfolio of the Trust.
   The  Distribution Plan recognizes that N&B  Management may use its assets and
resources, including its profits from  administration fees paid by a  Portfolio,
to  pay expenses associated with the  distribution of Portfolio shares. However,
N&B Management will  not receive  any separate fees  for such  expenses. To  the
extent  that any payments  made by a  Portfolio should be  deemed to be indirect
financing of any activity primarily intended to result in the sale of shares  of
the  Portfolio within the  context of Rule  12b-1 under the  1940 Act, then such
payments shall be deemed to be authorized by the Distribution Plan.
   Under the Distribution  Plan, the  Portfolio will require  N&B Management  to
provide  the Trust with quarterly reports  of the amounts expended in connection
with financing  any  activity  primarily  intended to  result  in  the  sale  of
Portfolio  shares,  and the  purpose for  which such  expenditure was  made. The
Distribution Plan may be terminated as to a particular Portfolio at any time  by
a  vote of a majority of the independent trustees of the Trust or by a vote of a
majority  of  the   outstanding  voting  securities   of  that  Portfolio.   The
Distribution  Plan does not require N&B  Management to perform any specific type
or level of distribution activities or  to incur any specific level of  expenses
for  activities  primarily intended  to  result in  the  sale of  shares  of the
Portfolio.
 
                                                                              25

DESCRIPTION OF INVESTMENTS
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Balanced Investments, as  indicated below, may  make the following  investments,
among  others,  individually  or in  combination,  although the  Series  may not
necessarily buy any or all of the types  of securities or use any or all of  the
investment  techniques that are  described. These investments  may be limited by
the requirements  with which  the Series  must  comply if  the Portfolio  is  to
qualify  as regulated investment companies for  tax purposes. The use of hedging
or other techniques is discretionary and no representation is made that the risk
of AMT Balanced Investments will be reduced by the techniques discussed in  this
section.  For additional information  on the following  investments and on other
types of investments the Series may make, see the SAI.
    
 
    U.S. GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities  are
obligations  of the  U.S.Treasury backed  by the  full faith  and credit  of the
United States. U.S.  Government Agency  securities are issued  or guaranteed  by
U.S.  Government agencies, instrumentalities, or other U.S. Government-sponsored
enterprises, such  as the  Government  National Mortgage  Association  ("GNMA"),
Federal  National  Mortgage  Association ("FNMA"),  Federal  Home  Loan Mortgage
Corporation ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee  Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may  be backed by the  full faith and credit of  the United States, the issuer's
ability to borrow from the U.S.  Treasury, subject to the Treasury's  discretion
in  certain cases,  or only  by the  credit of  the issuer.  U.S. Government and
Agency securities include certain mortgage-backed securities. The market  prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID  SECURITIES. The Series may  invest up to 10%  of its net assets in
securities that are illiquid, in that they cannot be expected to be sold  within
seven  days at  approximately the  price at  which they  are valued.  Due to the
absence of an  active trading market,  the Series may  experience difficulty  in
valuing  or  disposing of  illiquid  securities. N&B  Management  determines the
liquidity of  the  Series' securities,  under  supervision of  the  trustees  of
Managers Trust. Securities which are freely tradeable in their country of origin
or  in their principal market will not be considered illiquid securities even if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally outside the  U.S., including non-U.S.  governments, their  agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated in or indexed to foreign  currencies, which may also be affected  by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective of the  performance of  the underlying  investment. N&B  Management
considers  these  factors in  making investments  for  the Series.  AMT Balanced
Investments may  enter  into  forward  foreign  currency  contracts  or  futures
contracts (agreements to exchange one currency for another at a future date) and
related  options  to manage  currency risks  and  to facilitate  transactions in
foreign securities. Although these contracts can protect the Series from adverse
exchange rate changes, they involve  a risk of loss  if N&B Management fails  to
predict foreign currency values correctly.
   
   AMT  Balanced Investments  may invest  up to  10% of  the value  of its total
assets, measured  at the  time of  investment, in  foreign securities  that  are
issued  by non-United  States entities. The  10% limitation does  not apply with
respect to foreign securities  that are denominated  in U.S. dollars,  including
ADRs.  Foreign securities (including those denominated in U.S. dollars and ADRs)
are affected by political or economic developments in foreign countries.
    
   
   Investments in foreign securities could be affected by factors generally  not
thought  to be present in the U.S. Such factors include, but are not limited to,
varying custody, brokerage and settlement practices; difficulty in pricing  some
    
 
26
<PAGE>
   
foreign  securities; less public  information about issuers  of securities; less
governmental regulation and supervision over issuance and trading of securities;
the unavailability of  financial information or  the difficulty of  interpreting
financial   information  prepared  under   foreign  accounting  standards;  less
liquidity and more volatility in foreign securities markets; the possibility  of
expropriation; the imposition of foreign withholding and other taxes; political,
social,  or diplomatic  developments; limitations  on the  movement of  funds or
other assets of the Series between different countries; difficulties in invoking
legal process abroad and enforcing  contractual obligations; and the  difficulty
of  assessing  economic  trends  in  foreign  countries.  Investment  in foreign
securities also  involves  higher brokerage  and  custodian expenses  than  does
investment in domestic securities.
    
   In addition, investing in securities of foreign companies and governments may
involve  other  risks  which are  not  ordinarily associated  with  investing in
domestic securities. These risks include changes in currency exchange rates  and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions  applicable  to  such   investments  or  devaluations  of   foreign
currencies.  A decline in  the exchange rate  would reduce the  value of certain
portfolio  securities  irrespective  of   the  performance  of  the   underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and  changes in rates  of exchange with  the U.S. dollar  because the underlying
security is usually denominated in foreign currency. All of the foregoing  risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN  CURRENCY TRANSACTIONS.  The Series  may enter  into forward foreign
currency exchange  contracts in  order  to protect  against adverse  changes  in
future  foreign currency exchange  rates, to facilitate  transactions in foreign
securities and to  repatriate dividend  or interest income  received in  foreign
currencies.  The Series may enter into  contracts to purchase foreign currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends to purchase. The  Series may also enter  into contracts to sell  foreign
currencies  to  protect  against a  decline  in  value of  its  foreign currency
denominated portfolio  securities due  to  a decline  in  the value  of  foreign
currencies  against the  U.S. dollar. Contracts  to sell  foreign currency could
limit any potential gain which might be  realized by the Series if the value  of
the hedged currency increased.
   The  Series may also  enter into forward  foreign currency exchange contracts
for non-hedging  purposes  when  the investment  adviser  anticipates  that  the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated in that currency do not present attractive investment  opportunities
and  are not held in the Series. The  Series may also engage in cross-hedging by
using forward contracts  in one currency  to hedge against  fluctuations in  the
value  of  securities  denominated in  a  different currency  if  the investment
adviser believes  that  there  is  a pattern  of  correlation  between  the  two
currencies.
   If  the  Series enters  into  a forward  currency  exchange contract  to sell
foreign currency, it may  be required to  place cash or  high grade liquid  debt
securities  in  a segregated  account in  an amount  equal to  the value  of the
Series' total  assets committed  to the  consummation of  the forward  contract.
Although  these contracts  can protect the  Series from  adverse exchange rates,
they involve risk of  loss if N&B Management  fails to predict foreign  currency
values correctly.
 
    PUT  AND CALL OPTIONS, FUTURES CONTRACTS,  OPTIONS ON FUTURES CONTRACTS. The
Series may  try  to reduce  the  risk of  securities  price changes  (hedge)  or
generate  income by  writing (selling)  covered call  options against securities
held in its portfolio having a market value not exceeding 10% of its net  assets
and  may purchase call options in related closing transactions. The purchaser of
a call option acquires the  right to buy a portfolio  security at a fixed  price
during
 
                                                                              27
<PAGE>
a  specified period. The  maximum price the  seller may realize  on the security
during the option period is  the fixed price. The  seller continues to bear  the
risk  of a decline in the security's price, although this risk is reduced by the
premium received for the option.
   The Series also  may try to  manage portfolio duration  by (1) entering  into
interest-rate  futures contracts traded on  futures exchanges and (2) purchasing
and writing options on futures contracts.
   
   The Series also may try  to reduce the risk  of securities price changes  and
expected  changes in  prevailing currency exchange  rates (hedge)  and may write
covered call  options  and  purchase  put options  on  debt  securities  in  its
portfolio  or on foreign currencies  for hedging purposes or  for the purpose of
producing income. The Series will write  call options on a security or  currency
only  if it  holds that  security or  currency or  has the  right to  obtain the
security or currency at no  additional cost. These investment practices  involve
certain  risks,  including transactional  expense, price  volatility and  a high
degree of leverage. The Series may  engage in transactions in futures  contracts
and  related options only  as permitted by regulations  of the Commodity Futures
Trading Commission.
    
   The writing and purchasing of options is a highly specialized activity  which
involves  investment techniques and  risks different from  those associated with
ordinary portfolio  securities  transactions  including  transactional  expense,
price  volatility and a  high degree of  leverage. The writing  of options could
result in significant increases in the Series' turnover rate.
   The primary  risks in  using put  and call  options, futures  contracts,  and
options  on futures contracts, and forward foreign currency contracts or options
on foreign currencies ("Hedging Instruments")  are (1) imperfect correlation  or
no  correlation between changes  in market value  of the securities  held by the
Series and the prices of the Hedging Instruments; (2) possible lack of a  liquid
secondary  market for Hedging  Instruments and the  resulting inability to close
out a Hedging Instrument when  desired; (3) the fact  that the skills needed  to
use  Hedging Instruments are  different from those needed  to select the Series'
securities; (4) the  fact that, although  use of these  instruments for  hedging
purposes  can reduce the risk of loss,  they also can reduce the opportunity for
gain, or  even result  in losses,  by offsetting  favorable price  movements  in
hedged  investments; and (5) the possible inability of the Series to purchase or
sell a security at a time that would otherwise be favorable for it to do so,  or
the  possible need for the Series to  sell a security at a disadvantageous time,
due to its  need to maintain  "cover" or to  segregate securities in  connection
with its use of these instruments. Futures, options and forward foreign currency
contracts are considered derivatives.
 
    FORWARD  COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or forward
commitment transaction, the Series  commits to purchase  securities in order  to
secure  an advantageous price and  yield at the time  of the commitment and pays
for the securities when  they are delivered at  a future date (generally  within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity  to obtain  a favorable price  and yield.  When-issued securities or
securities subject to  a forward  commitment may  decline or  increase in  value
during  the period from  the Series' investment commitment  to the settlement of
the purchase which may magnify fluctuation in the Series' NAV.
 
    INDEXED SECURITIES. The Series may invest in indexed securities whose  value
is  linked  to  currencies,  interest  rates,  commodities,  indices,  or  other
financial indicators.  Most indexed  securities are  short-to-intermediate  term
fixed-income  securities whose values at maturity or interest rates rise or fall
according to the change in one or more specified underlying instruments. Indexed
securities may  be  positively or  negatively  indexed (i.e.,  their  value  may
increase  or decrease  if the underlying  instrument appreciates),  and may have
return  characteristics  similar  to   direct  investments  in  the   underlying
instrument  or  to one  or more  options on  the underlying  instrument. Indexed
securities may be more volatile than the underlying instrument itself.
 
28
<PAGE>
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements and lend securities  from its portfolio.  In a repurchase  agreement,
the  Series buys a security from a  Federal Reserve member bank, or a securities
dealer and  simultaneously agrees  to  sell it  back at  a  higher price,  at  a
specified  date, usually less than a  week later. The underlying securities must
fall within the Series' investment policies and limitations (but not limitations
as to maturity or  duration). The Series also  may lend portfolio securities  to
banks, brokerage firms, or institutional investors to earn income. Costs, delays
or  losses could result  if the selling  party to a  repurchase agreement or the
borrower of portfolio  securities becomes  bankrupt or  otherwise defaults.  N&B
Management monitors the creditworthiness of sellers and borrowers.
 
    REVERSE  REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.  In a  reverse repurchase
agreement, the Series sells securities to a bank or securities dealer and at the
same time agrees to repurchase  the same securities at a  later date at a  fixed
price.  During the period before the repurchase, the Series continues to receive
principal and interest payments on the securities. In a dollar roll, the  Series
sells  securities for delivery in the current month and simultaneously contracts
to repurchase  substantially similar  (same  type and  coupon) securities  on  a
specified  future  date  from  the  same party.  During  the  period  before the
repurchase,  the  Series  forgoes  principal   and  interest  payments  on   the
securities.  The Series  is compensated  by the  difference between  the current
sales price and the forward price for the future purchase (often referred to  as
the  "drop"), as  well as  by the interest  earned on  the cash  proceeds of the
initial sale. Reverse repurchase  agreements and dollar  rolls may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements and dollar rolls.
 
    CONVERTIBLE SECURITIES. The Series may  invest in convertible securities.  A
convertible  security  is a  bond, debenture,  note,  preferred stock,  or other
security that may  be converted  into or exchanged  for a  prescribed amount  of
common  stock of the  same or a  different issuer within  a particular period of
time at a  specified price  or formula.  Many convertible  securities are  rated
below investment grade, or, are unrated.
 
    MORTGAGE-BACKED  SECURITIES. Mortgage-backed  securities represent interests
in, or  are secured  by and  payable from,  pools of  mortgage loans,  including
collateralized  mortgage obligations.  These securities  may be  U.S. Government
mortgage-backed securities, which are issued or guaranteed by a U.S.  Government
agency  or instrumentality (though not necessarily  backed by the full faith and
credit of the United States), such  as GNMA, FNMA and FHLMC certificates.  Other
mortgage-backed  securities are issued by private issuers, generally originators
of and investors  in mortgage  loans, including  savings associations,  mortgage
bankers,  commercial banks,  investment bankers,  and special  purpose entities.
These private mortgage-backed  securities may  be supported  by U.S.  Government
mortgage-backed  securities or  some form of  non-government credit enhancement.
Mortgage-backed securities may have either  fixed or adjustable interest  rates.
Tax  or regulatory changes may adversely  affect the mortgage securities market.
In addition, changes  in the market's  perception of the  issuer may affect  the
value  of  mortgage-backed securities.  The  rate of  return  on mortgage-backed
securities may be affected by prepayments of principal on the underlying  loans,
which  generally increase as interest rates  decline; as a result, when interest
rates decline,  holders  of  these  securities  normally  do  not  benefit  from
appreciation in market value to the same extent as holders of other non-callable
debt  securities. N&B Management  determines the effective  life and duration of
mortgage-backed  securities  based  on  industry  practice  and  current  market
conditions.  If N&B Management's determination is  not borne out in practice, it
could positively  or negatively  affect  the value  of  the Series  when  market
interest  rates change.  Increasing market  interest rates  generally extend the
effective maturities of mortgage-backed securities.
 
                                                                              29
<PAGE>
    ASSET-BACKED SECURITIES. Asset-backed securities represent interests in,  or
are  secured  by and  payable  from pools  of  assets, such  as  consumer loans,
CARS-SM- ("Certificates  for Automobile  Receivables"), credit  card  receivable
securities,  and installment  loan contracts.  Although these  securities may be
supported by letters of credit or other credit enhancements, payment of interest
and principal ultimately depends upon  individuals paying the underlying  loans.
The  risk  that  recovery on  repossessed  collateral might  be  unavailable, or
inadequate to support payments on asset-backed securities is greater than in the
case of mortgage-backed securities.
 
    OTHER INVESTMENTS. When market conditions  warrant the Series may invest  in
preferred stocks, securities convertible into or exchangeable for common stocks,
U.S.  Government  and Agency  Securities, investment  grade debt  securities, or
money market instruments, or may retain assets in cash or cash equivalents.
 
    SHORT SELLING. The Series may attempt to limit exposure to a possible market
decline in the value of portfolio  securities through short sales of  securities
which the investment adviser believes possess volatility characteristics similar
to  those being hedged and may use short sales in an attempt to realize gain. To
effect such a transaction,  the Series will borrow  a security from a  brokerage
firm  to make delivery to the buyer. The Series then is obligated to replace the
security borrowed  by  purchasing  it  at  the  market  price  at  the  time  of
replacement.  Until the security is  replaced, the Series is  required to pay to
the lender  any accrued  interest  or dividend  and may  be  required to  pay  a
premium.
   The  Series will realize a gain if the security declines in price between the
date of the short sale  and the date on which  the Series replaces the  borrowed
security.  The Series will incur  a loss if the  price of the security increases
between those dates. The amount of any gain will be decreased, and the amount of
any loss increased, by the amount of  any premium or interest the Series may  be
required  to pay in  connection with a  short sale. The  successful use of short
selling may be adversely affected by imperfect correlation between movements  in
the  price of  the security  sold short and  the securities  being hedged. Short
selling may defer recognition of gains or losses into another tax period.
   
   AMT Balanced Investments may make  short sales against-the-box. A short  sale
is  "against-the-box" when, at all times during  which a short position is open,
the Series own an equal amount of  such securities, or own securities giving  it
the right, without payment of future consideration, to obtain an equal amount of
securities sold short.
    
 
    VARIABLE AND FLOATING RATE SECURITIES. Variable and floating rate securities
have  interest  rate adjustment  formulas that  help  to stabilize  their market
value. Many of these instruments carry a demand feature which permits the Series
to sell them during a determined time period at par value plus accrued interest.
The demand feature is often backed by  a credit instrument, such as a letter  of
credit,  or by a creditworthy insurer. The Series may rely on such instrument or
the creditworthiness of the  insurer in purchasing a  variable or floating  rate
security.
 
    ZERO   COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay  interest
currently; instead, they are sold  at a discount from  their face value and  are
redeemed  at face value when  they mature. Because zero  coupon bonds do not pay
current income, their prices can be very volatile when interest rates change. In
calculating its daily  income, the Series  accrues a portion  of the  difference
between a zero coupon bond's purchase price and its face value.
 
    MUNICIPAL  OBLIGATIONS. Municipal obligations are issued  by or on behalf of
states, the District of Columbia, and U.S. territories and possessions and their
political  subdivisions,  agencies,  and  instrumentalities.  The  interest   on
municipal  obligations is exempt from  federal income tax. Municipal obligations
include "general obligation"  securities, which  are backed by  the full  taxing
power  of  a municipality,  and "revenue"  securities, which  are backed  by the
income from a  specific project,  facility, or tax.  Municipal obligations  also
include  industrial development  and private activity  bonds --  the interest on
which may  be a  tax preference  item for  purposes of  the federal  alternative
minimum  tax -- which are  issued by or on behalf  of public authorities and are
not backed by the credit of any governmental or public authority.  "Anticipation
notes"  are issued by municipalities in  expectation of future proceeds from the
issuance
 
30
<PAGE>
of bonds, or  from taxes  or other  revenues, and  are payable  from those  bond
proceeds,  taxes,  or revenues.  Municipal  obligations also  include tax-exempt
commercial paper, which is issued  by municipalities to help finance  short-term
capital  or operating requirements.  Current efforts to  restructure the federal
budget and the relationship between the  federal government and state and  local
governments  may impact the  financing of some  issuers of municipal securities.
Some states and localities are experiencing substantial deficits and may find it
difficult for  political or  economic  reasons to  increase taxes.  Efforts  are
underway  that may result in a "flat  tax" or other restructuring of the federal
income tax system. These  developments could reduce the  value of all  municipal
securities, or the securities of particular issuers.
 
    RESTRICTED  SECURITIES AND  RULE 144A SECURITIES.  The Series  may invest in
restricted securities and Rule 144A securities. Restricted securities cannot  be
sold  to the public without registration under the Securities Act of 1933 ("1933
Act"). Unless  registered  for  sale,  these securities  can  be  sold  only  in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted  securities are generally considered  illiquid. Rule 144A securities,
although not registered, may be resold only to qualified institutional buyers in
accordance with Rule 144A under the  1933 Act. Unregistered securities may  also
be  sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.
 
                                                                              31

USE OF JOINT PROSPECTUS AND STATEMENT
OF ADDITIONAL INFORMATION
   Each Portfolio and its  corresponding Series acknowledges  that it is  solely
responsible  for all information or lack of information about that Portfolio and
Series in the SAI, and no other Portfolio or Series is responsible therefor. The
trustees of  the Trust  and of  Managers Trust  have considered  this factor  in
approving each Portfolio's and Series' use of a single combined SAI.

          By Exchanging Shares
 
- --------------------------------------------------------------------------------
 
   Call 800-877-9700 for instructions on how  to invest by exchanging shares  of
another  Neuberger&Berman  Fund-SM-  for shares  of  the Portfolio.  To  buy the

same name, address, and taxpayer ID number. The minimum for a FIRST PURCHASE and
for each ADDITIONAL PURCHASE of shares of the Portfolio by an exchange is $1,000
worth  of  shares  of  the  other  fund.  For  more  details,  see  "Shareholder

          Other Information
 
- --------------------------------------------------------------------------------
 
   / / You must pay  for your shares  in U.S.  dollars by check  or money  order
       (drawn  on a U.S. bank), or by  bank or federal funds wire transfer; cash
       cannot be accepted.
   / / The Portfolio has the right to suspend  the offering of its shares for  a
       period  of time. The Portfolio  also has the right  to accept or reject a
       purchase order in its sole discretion, including certain purchase  orders
       using  the  exchange  privilege. See  "Shareholder  Services  -- Exchange
       Privilege."
   / / If you paid by  check and your  check does not clear,  or if you  ordered
       shares  by telephone  and fail  to pay  for them,  your purchase  will be
       canceled and you  could be liable  for any resulting  losses or fees  the
       Portfolio  or its agents have incurred.  To recover those losses or fees,
       the Portfolio has the  right to bill  you or to  redeem shares from  your
       account.
   / / When  you sign  your application for  the Portfolio account,  you will be
       certifying that  your Social  Security  or other  taxpayer ID  number  is
       correct and whether you are subject to backup withholding. If you violate
       certain  federal income tax provisions,  the Internal Revenue Service can
       require the Portfolio to withhold  31% of your taxable distributions  and
       redemptions.

HOW TO SELL SHARES
   You  can  sell (redeem)  all or  some of  your  shares at  any time  by mail,
facsimile, or telephone. You can also sell shares by exchanging them for  shares
of  other  Neuberger&Berman  Funds-SM-; see  "Shareholder  Services  -- Exchange
Privilege" for details.
   Your shares are sold at the next price calculated on a day the NYSE is  open,
after  your sales order is received and  accepted. Prices for shares are usually
calculated as of 4 p.m. Eastern time.
   Unless otherwise instructed, the Portfolio will  mail a check for your  sales
proceeds, payable to the owner(s) shown on your account ("record owner"), to the
address  shown on  your account  ("record address").  You may  designate in your
Portfolio application a  bank account to  which, at your  request, State  Street
will  wire your sales proceeds of $1,000 or more. State Street currently charges
a fee of $8.00 for each wire, payable  to you. However, if you have one or  more
accounts  in  the Neuberger&Berman  Funds-SM-  aggregating $250,000  or  more in
value, you will not be charged for wire redemptions; your $8.00 fee will be paid
by N&B Management.

want to sell, together with any other instructions, and send it by mail to:
   Neuberger&Berman Funds
   Boston Service Center
   P.O. Box 8403

or by overnight courier, U.S. Express Mail, or registered or certified mail to:
 
   Neuberger&Berman Funds
   c/o State Street Bank and Trust Company
   2 Heritage Drive
   North Quincy, MA 02171
 
or  by facsimile, to redeem  up to $50,000 worth  of shares, to 212-476-8848. In
addition, if  you have  changed the  record address  by telephone  or  facsimile
(permitted  beginning June 1, 1995), shares may not be redeemed by facsimile for
15 days after receipt of the address change. Please call 800-877-9700 to confirm
receipt and acceptance of your order submitted by facsimile.
   Be sure to have all owners sign the request exactly as their names appear  on
the account and include the certificate for your shares if you have one.
   To  protect  you  and  the  Portfolio  against  fraud,  your  signature  on a
redemption request must have a SIGNATURE GUARANTEE if (1) you want to sell  more
than  $50,000 worth of shares,  or (2) you want the  redemption check to be made
out to someone  other than the  record owner, or  (3) you want  the check to  be
mailed  somewhere other than to the record address, or (4) you want the proceeds
to be wired to a bank account not  named in your application or in your  written
instruction  with a  signature guarantee. You  can obtain  a signature guarantee
from most banks, stockbrokers  and dealers, credit  unions, and other  financial
institutions, but not from a notary public.
 
                                                                              37
<PAGE>
   For a redemption request sent by FACSIMILE, limited to not more than $50,000,
the  redemption check may only be made out to the record owner and mailed to the
record address or the proceeds wired to a bank account named in your application
or in a written instruction from the record owner with a signature guarantee.
 
          By Telephone
 
- --------------------------------------------------------------------------------
 
   To sell shares worth at least  $500, call 800-877-9700, giving your name  and
account  number, the name of  the Portfolio, and the  dollar amount or number of
shares you want to sell.
   You can sell shares by telephone unless you have declined this service either
in your application or later by writing or by submitting an appropriate form  to
State  Street. In addition, if you have  changed the record address by telephone
or facsimile (permitted beginning June 1,  1995), shares may not be redeemed  by
telephone for 15 days after receipt of the address change.
   Please refer to "Additional Information on Telephone Transactions."
 
          Other Information
 
- --------------------------------------------------------------------------------
 
   / / Usually,  redemption proceeds will be mailed  to you on the next business
       day,  but  in  any  case  within  three  calendar  days  (under   unusual
       circumstances  the Portfolio may  take longer, as  permitted by law). You
       may also call  800-877-9700 for information  on how to  make and  receive
       electronic transfers through your bank.
   / / The  Portfolio may delay paying for any redemption until it is reasonably
       satisfied that the check used to  buy shares has cleared, which may  take
       up  to 15  days after the  purchase date. So  if you plan  to sell shares
       shortly after buying them, you  may want to pay  for the purchase with  a
       certified check or money order or by wire transfer.
   / / The  Portfolio may suspend redemptions or  postpone payments on days when
       the NYSE is closed (besides weekends  and holidays), when trading on  the
       NYSE  is  restricted,  or as  permitted  by the  Securities  and Exchange
       Commission.
   / / If, because  you sold  shares, your  account balance  with the  Portfolio
       falls  below $1,000,  the Portfolio has  the right to  close your account
       after giving you  at least  60 days'  written notice  to reestablish  the
       minimum  balance. If  you do  not do  so, the  Portfolio may  redeem your
       remaining shares at  their per share  NAV on the  date of redemption  and
       will send the redemption proceeds to you.

ADDITIONAL INFORMATION ON TELEPHONE TRANSACTIONS
   The  Portfolio at any time can limit the  number of its shares you can buy by
telephone or  can stop  accepting telephone  orders. You  can sell  or  exchange
shares by telephone, unless you have declined these services in your application
or  by written  notice to  N&B Management or  State Street,  with your signature
guaranteed. The Portfolio or its agent follows reasonable
procedures -- requiring you  to provide a form  of personal identification  when
you  telephone,  recording  your  telephone  call,  and  sending  you  a written
confirmation of each telephone transaction -- designed to confirm that telephone
instructions are  genuine.  However, neither  the  Portfolio nor  its  agent  is
responsible  for the  authenticity of telephone  instructions or  for any losses
caused by fraudulent or unauthorized telephone instructions if the Portfolio  or
its agent reasonably believed that the instructions were genuine.
   If  you are unable to  reach N&B Management by  telephone (which might be the
case, for example, during periods of unusual market activity), consider  sending
your  transaction instructions by facsimile,  overnight courier, or U.S. Express
Mail.
 
          Exchange Privilege
 
- --------------------------------------------------------------------------------
 
   To  exchange   your  shares   in  the   Portfolio  for   shares  in   another
Neuberger&Berman  Fund-SM-, call 800-877-9700 between 8 a.m. and 4 p.m., Eastern
time, on any Monday  through Friday (unless  the NYSE is  closed). You may  also
effect   an  exchange  by  sending   a  letter  to  Neuberger&Berman  Management
Incorporated, 605 Third Avenue, 2nd  Floor, New York, NY 10158-0006,  Attention:
[Name  of fund], or by  sending the letter by  facsimile to 212-476-8848, giving
your name and account number, the name of the fund, the dollar amount or  number
of  shares you want to sell,  and the name of the  fund whose shares you want to
buy. Please call 800-877-9700  to confirm receipt and  acceptance of your  order
submitted  by facsimile. You can use the telephone exchange privilege unless you
have declined it in your  application or by later  writing to N&B Management  or
State  Street. An exchange must  be for at least $1,000  worth of shares, and if
the exchange is your FIRST  PURCHASE in another mutual fund,  it must be for  at
least  the minimum initial investment amount for that fund. Shares are exchanged
at their next prices calculated on a  day the NYSE is open, after your  exchange
order is received and accepted.
   Please note the following about the exchange privilege:
   / / You  can exchange  shares only  between accounts  registered in  the same
       name, address, and taxpayer ID number.
   / / A telephone exchange order cannot be modified or canceled.
   / / You can exchange only  into a mutual fund  whose shares are eligible  for
       sale in your state under applicable state securities laws.
   / / An exchange may have tax consequences for you.
   / / Because  excessive trading (including short-term "market timing" trading)
       can hurt a fund's performance, a fund may refuse any exchange orders  (1)
       if  they appear  to be  market-timing transactions  involving significant
       portions of a fund's  assets or (2) from  any shareholder account if  the
       shareholder  has been advised that previous use of the exchange privilege
       was considered  excessive. Accounts  under common  ownership or  control,
       including  those with the same taxpayer ID number, will be considered one
       account for this purpose.
   / / The Portfolio or any fund may  impose other restrictions on the  exchange
       privilege, or modify or terminate the privilege, but will try to give you
       advance notice whenever it can reasonably do so.
   Please refer to "Additional Information on Telephone Transactions."

- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of one of the  Portfolios
are  also offered directly to qualified pension and retirement plans ("Qualified
Plans").
   THIS PROSPECTUS  CONTAINS INFORMATION  PERTAINING  TO THE  GOVERNMENT  INCOME
PORTFOLIO ONLY.
 
- --------------------------------------------------------------------------------
 
   
   EACH  PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS CORRESPONDING
SERIES (EACH  A "SERIES")  OF  ADVISERS MANAGERS  TRUST ("MANAGERS  TRUST"),  AN
OPEN-END  MANAGEMENT INVESTMENT COMPANY. AMT  GOVERNMENT INCOME INVESTMENTS, THE
GOVERNMENT   INCOME   PORTFOLIO'S   CORRESPONDING   SERIES,   IS   MANAGED    BY
NEUBERGER&BERMAN  MANAGEMENT  INCORPORATED  ("N&B  MANAGEMENT").  AMT GOVERNMENT
INCOME INVESTMENTS  INVESTS  IN  SECURITIES IN  ACCORDANCE  WITH  AN  INVESTMENT
OBJECTIVE, POLICIES, AND LIMITATIONS IDENTICAL TO THOSE OF THE GOVERNMENT INCOME
PORTFOLIO.  THE INVESTMENT PERFORMANCE  OF THE GOVERNMENT  INCOME PORTFOLIO WILL
DIRECTLY CORRESPOND WITH  THE INVESTMENT  PERFORMANCE OF  AMT GOVERNMENT  INCOME
INVESTMENTS.  THIS "MASTER/FEEDER FUND" STRUCTURE IS DIFFERENT FROM THAT OF MANY
OTHER  INVESTMENT  COMPANIES  WHICH  DIRECTLY  ACQUIRE  AND  MANAGE  THEIR   OWN
PORTFOLIOS OF SECURITIES. FOR MORE INFORMATION ON THIS UNIQUE STRUCTURE THAT YOU
SHOULD    CONSIDER,   SEE    "SPECIAL   INFORMATION    REGARDING   ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS" ON PAGE 10.

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and limitations  that are  identical to  those of  the Portfolio.  The
trustees  of the  Trust believe  that this  "master/ feeder  fund" structure may
benefit shareholders.  For  more  information  about  the  organization  of  the
Portfolios  and the Series, including certain features of the master/feeder fund
structure, see "Special Information Regarding Organization, Capitalization,  and
Other  Matters"  on  page  10.  For more  details  about  AMT  Government Income
Investments, its investments and their  risks, see "Investment Program" on  page
6,  "Ratings of Securities" on page 7,  "Borrowings" on page 7, and "Description
of Investments" on page 20.
    
   Here is a summary  of important features of  the Government Income  Portfolio
and  its  corresponding Series.  Of course,  there  can be  no assurance  that a
Portfolio will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An investment in  any Portfolio  involves certain risks,  depending upon  the
types  of investments  made by  its corresponding  Series. Special  risk factors
apply to investments which may be  made by AMT Government Income Investments  in
foreign  securities, options and  futures contracts, zero  coupon bonds and swap
agreements.  AMT  Government   Income  Investments  invests   in  fixed   income
securities,  the value of which is likely to decline in times of rising interest
rates and rise in times  of falling interest rates.  In general, the longer  the
maturity  of a  fixed income security,  the more  pronounced is the  effect of a
change in interest rates on the value of the security.
    
   AMT Government Income Investments invests at least 25% of its total assets in
mortgage-backed and  asset-backed securities,  may engage  in lending  portfolio
securities  and other  investment techniques, and  may borrow  for leverage. The
investment program of AMT Government  Income Investments is intended to  protect
principal  by  focusing on  the credit  quality of  the issuers.  Principal may,
however, be at risk due to market rate fluctuations.

  number of shares outstanding during each year.
    
   
2)The per share amounts and ratios which are shown reflect income and  expenses,

5)Annualized.
    
   
6)Since the  commencement  of  operations, N&B  Management  voluntarily  assumed
  certain operating expenses of the Portfolio as described in Note B of Notes to
  Financial  Statements and in  this Prospectus under  "Expense Limitation." Had
  such action not  been undertaken, the  annualized ratios of  expenses and  net
  investment income to average daily net assets would have been 4.21% and 2.55%,
  respectively,  for  the year  ended December  31, 1995,  and 2.57%  and 3.30%,
  respectively, for the period ended December 31, 1994.
    
   
7)The Portfolio transferred all of its investment securities into its Series  on
  April  28, 1995. After that date the Portfolio invested only in its Series and
  that Series, rather  than the Portfolio,  engaged in securities  transactions.
  Therefore,  after that date the Portfolio  had no portfolio turnover rate. The
  portfolio turnover rate for AMT  Government Income Investments for the  period
  from May 1, 1995 to December 31, 1995 was 64%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in  net asset value  on the performance  of the Portfolio  during each year and
 assumes dividends  and capital  gain distributions,  if any,  were  reinvested.
 Results  represent  past  performance  and  do  not  guarantee  future results.
 Investment returns and principal may fluctuate and shares when redeemed may  be
 worth  more or less  than original cost.  Total return figures  would have been
 lower if N&B  Management had  not limited  certain expenses.  The total  return
 information  shown does not reflect expenses that apply to the separate account
 or the related  insurance policies, and  the inclusion of  these charges  would
 reduce the total return figures for all years shown.

INVESTMENT PROGRAM
    
   
   The  investment policies and  limitations of the  Government Income Portfolio
and AMT  Government  Income Investments  are  identical. The  Government  Income
Portfolio  invests  only in  AMT Government  Income Investments.  Therefore, the
following shows  you the  kinds of  securities in  which AMT  Government  Income
Investments  invests.  For  an explanation  of  some types  of  investments, see
"Description of Investments" on page 20.
    
   Investment policies and  limitations of the  Government Income Portfolio  and
AMT Government Income Investments are not fundamental unless otherwise specified
in  this Prospectus or the SAI. While a non-fundamental policy or limitation may
be changed by the trustees of the Trust or of Managers Trust without shareholder
approval, the Government Income Portfolio intends to notify shareholders  before
making any material change to such policies or limitations. Fundamental policies
and limitations may not be changed without shareholder approval. There can be no
assurance  that  AMT Government  Income  Investments and  the  Government Income
Portfolio will achieve  their objectives.  The Government  Income Portfolio,  by
itself, does not represent a comprehensive investment program.
   
   Additional  investment techniques,  features, and  limitations concerning AMT
Government Income Investments' investment program are described in the SAI.
    
 
          AMT Government Income Investments
 
- --------------------------------------------------------------------------------
 
   The investment  objective  of  AMT  Government  Income  Investments  and  the
Government  Income Portfolio is  to provide a  high level of  current income and
total return, consistent with safety of principal. This investment objective  is
non-fundamental. The Portfolio intends to notify shareholders 30 days in advance
of making any material change to its investment objective.
   AMT Government Income Investments invests in a diversified portfolio of fixed
and  variable rate debt securities and seeks  to increase income and preserve or
enhance total return by actively managing average portfolio duration in light of
market conditions and trends.
   AMT Government Income Investments invests at least 65% of its total assets in
U.S. Government  and Agency  securities,  with an  emphasis on  U.S.  Government
mortgage-backed  securities. In addition, the Series invests at least 25% of its
total  assets   in  mortgage-backed   securities  (including   U.S.   Government
mortgage-backed  securities) and  asset-backed securities.  The Series  may also
invest in investment  grade debt securities,  including foreign investments  and
securities  issued by financial institutions  and corporations, and may purchase
and sell  covered  call and  put  options, interest-rate  and  foreign  currency
futures contracts, and options on those futures contracts. Although there are no
restrictions  on the  duration composition of  its portfolio  of securities, the
Series anticipates  that  it  normally  will  invest  in  intermediate-term  and
longer-term securities, but will remain flexible to respond to market conditions
and interest rate trends. The Series may engage in lending portfolio securities,
short-term trading, purchasing forward commitments on securities, and repurchase
agreements,  and  may use  leverage.  The investment  program  of the  Series is
intended to protect principal by focusing on the credit quality of the  issuers.
Principal may, however, be at risk due to market rate fluctuations.
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   AMT  Government  Income Investments  may engage  in  short-term trading  to a
substantial degree to take advantage  of anticipated changes in interest  rates.
This investment policy may be considered speculative.

<PAGE>
   
   The  portfolio turnover  rates for  the Government  Income Portfolio  and AMT
Government Income Investments, and for the predecessor of the Government  Income
Portfolio  for the period prior  to May 1, 1995,  are set forth under "Financial
Highlights" in  this Prospectus.  It is  anticipated that  the annual  portfolio
turnover rate of AMT Government Income Investments generally will exceed 100%.
    
   Turnover  rates in excess of 100% may result in higher costs (which are borne
directly by the Series) and a possible increase in short-term capital gains  (or
losses).
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
    HIGH  QUALITY DEBT SECURITIES.  High quality debt  securities are securities
that have received a rating from at least one nationally recognized  statistical
rating  organization ("NRSRO"), such as Standard  & Poor's Ratings Group ("S&P")
or Moody's Investors Service, Inc. ("Moody's"), in one of the two highest rating
categories (the highest  category in the  case of commercial  paper) or, if  not
rated  by any NRSRO,  such as U.S.  Government and Agency  securities, have been
determined by N&B Management to be of comparable quality.
 
   
    INVESTMENT GRADE  DEBT SECURITIES.  "Investment grade"  debt securities  are
those  receiving one of the  four highest ratings from  Moody's, S&P, or another
NRSRO or, if unrated by any NRSRO,  deemed comparable by N&B Management to  such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's  deems securities  rated in  its fourth  highest category  (Baa) to have
speculative characteristics;  a  change in  economic  factors could  lead  to  a
weakened capacity of the issuer to repay.
    
   If  the  quality  of securities  held  by AMT  Government  Income Investments
deteriorates so that the securities would  no longer satisfy its standards,  the
Series will engage in an orderly disposition of the downgraded securities to the
extent necessary to ensure that the Series' holdings of such securities will not
exceed 5% of the Series' net assets.
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT  Government Income Investments, as a fundamental policy, may borrow money
from banks  for any  purpose, including  to meet  redemptions and  increase  the
amount  available for investment,  and enter into  reverse repurchase agreements
(including dollar rolls)  for any purpose,  so long as  the aggregate amount  of
borrowings  and reverse repurchase  agreements does not  exceed one-third of the
Series' total assets  (including the  amount borrowed)  less liabilities  (other
than  borrowings).  Leveraging  (borrowing) to  increase  amounts  available for
investment may  exaggerate the  effect on  net asset  value of  any increase  or
decrease in the market value of the securities of the Series. Money borrowed for
leveraging  will be subject to interest costs  which may or may not be recovered
by income and appreciation of the securities purchased.
   Currently, the State of California imposes borrowing limitations on  variable
insurance  product funds.  To comply  with these  limitations, the  Series, as a
matter of operating policy, has undertaken that it will not borrow more than 10%
of its net  asset value  when borrowing  for any  general purpose  and will  not
borrow  more  than 25%  of its  net asset  value when  borrowing as  a temporary
measure to facilitate redemptions.  For these purposes, net  asset value is  the
market  value of all investments or assets owned less outstanding liabilities at
the time that any new or additional borrowing is undertaken.
 
                                                                               7
<PAGE>
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For temporary  defensive  purposes,  AMT Government  Income  Investments  may
invest  up  to 100%  of  its total  assets in  cash  and cash  equivalents, U.S.
Government and  Agency  Securities, commercial  paper  and certain  other  money
market  instruments,  as well  as  repurchase agreements  collateralized  by the
foregoing.  Also,  for  temporary  defensive  purposes,  AMT  Government  Income
Investments may adopt shorter weighted average duration than normal.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.
 
   
          Duration
    
 
- --------------------------------------------------------------------------------
 
   
   Duration  is a measure  of the sensitivity  of debt securities  to changes in
market interest  rates,  based on  the  entire  cash flow  associated  with  the
securities,   including  payments  occurring  before   the  final  repayment  of
principal. N&B Management  utilizes duration  as a tool  in portfolio  selection
instead of the more traditional measure known as "term to maturity" in portfolio
selection  for AMT  Government Income  Investments. "Term  to maturity" measures
only the  time until  a debt  security  provides its  final payment,  taking  no
account  of the pattern  of the security's payments  prior to maturity. Duration
incorporates a bond's yield, coupon  interest payments, final maturity and  call
features   into  one  measure.  Duration  therefore  provides  a  more  accurate
measurement of a bond's  likely price change  in response to  a given change  in
market  interest rates.  The longer the  duration, the greater  the bond's price
movement will be as  interest rates change. For  any fixed income security  with
interest  payments  occurring prior  to the  payment  of principal,  duration is
always less than maturity.
    
   
   Futures, options, and options on  futures have durations which are  generally
related  to the duration of the securities underlying them. Holding long futures
or call option positions  will lengthen a Fund's  duration by approximately  the
same  amount as would holding an equivalent amount of the underlying securities.
Short futures  or put  options  have durations  roughly  equal to  the  negative
duration of the securities that underlie these positions, and have the effect of
reducing portfolio duration by approximately the same amount as would selling an
equivalent amount of the underlying securities.
    
   
   There  are some situations where even  the standard duration calculation does
not properly reflect  the interest  rate exposure  of a  security. For  example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon  reset. Another example where the  interest rate exposure is not properly
captured by duration is the case of mortgage-backed securities. The stated final
maturity of such securities is generally 30 years, but current prepayment  rates
are critical in determining the securities' interest rate exposure. In these and
other  similar  situations,  N&B  Management,  where  permitted,  will  use more
sophisticated analytical  techniques that  incorporate the  economic life  of  a
security into the determination of its interest rate exposure.

PERFORMANCE INFORMATION
   
   Performance  information for the Government Income Portfolio may be presented
from time  to  time in  advertisements  and sales  literature.  The  Portfolio's
"yield"  is  calculated by  dividing the  Portfolio's annualized  net investment
income during a recent 30-day period by  the Portfolio's net asset value on  the
last  day of the period. The Portfolio's total return is quoted for the one-year
period and  for the  life of  the  Portfolio through  the most  recent  calendar
quarter,  and is determined by calculating the change in value of a hypothetical
$1,000 investment  in the  Portfolio for  each of  those periods.  Total  return
calculations  assume reinvestment  of all Portfolio  dividends and distributions
from net investment income and net realized gains, respectively.
    
   All performance  information presented  for the  Portfolio is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life Company separate accounts investing in the Trust which
will take  into  account  insurance-related  charges  and  expenses  under  such
insurance  policies and contracts. Further information regarding the Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of the Portfolio to various indices. Advertisements may also contain
the performance  rankings  assigned the  Portfolio  or its  adviser  by  various
publications  and  statistical services.  Any such  comparisons or  rankings are
based  on  past  performance  and  the  statistical  computations  performed  by
publications  and  services,  and  are  not  necessarily  indications  of future
performance. Because the Portfolio is a managed investment vehicle investing  in
a  wide variety of  securities, the securities  owned by the  Portfolio will not
match those  making up  an index.  Please note  that indices  do not  take  into
account  any fees  and expenses of  investing in the  individual securities that
they track and that individuals cannot invest in any index.
 
                                                                               9

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  the  International Portfolio  which  as of  December  31, 1995  had  not yet
commenced  investment  operations.  These  conversions  were  approved  by   the
shareholders  of  the  predecessors  of  the  Portfolios  in  August  1994. Each
Portfolio invests all of its net investable assets in its corresponding  Series,
in each case receiving a beneficial interest in that Series. The trustees of the
Trust  may establish  additional portfolios  or classes  of shares,  without the
approval of  shareholders. The  assets of  each Portfolio  belong only  to  that
Portfolio,  and  the liabilities  of  each Portfolio  are  borne solely  by that
Portfolio and no other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International Portfolio which  as of  December 31,  1995 had  not yet  commenced
investment   operations)   invested   all   of   its   net   investable   assets
    
 
10
<PAGE>
   
(cash, securities, and  receivables relating to  securities) in a  corresponding
Series  of Managers Trust,  receiving a beneficial interest  in that Series. The
assets of each Series belong  only to that Series,  and the liabilities of  each
Series are borne solely by that Series and no other.
    
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor  in the  Series other  than a  Portfolio redeemed  its interest  in the
Series, the Series' remaining  investors (including the  Portfolio) might, as  a
result,  experience higher pro rata  operating expenses, thereby producing lower
returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a  Portfolio withdrew  its investment  from the  Series, the  trustees
would  consider what action might  be taken, including the  investment of all of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the Portfolio of its own investment  manager to manage its assets in  accordance
with  its investment objective, policies, and  limitations. The inability of the
Portfolio to find  a suitable  replacement could  have a  significant impact  on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors  except as required by the 1940  Act. Each investor in the Series will
be entitled to  vote in proportion  to its relative  beneficial interest in  the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act  and  other  applicable  law,  a Portfolio  will  solicit  proxies  from its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
                                                                              11
<PAGE>
Portfolio's shareholders. Pursuant to current  interpretations of the 1940  Act,
the  Life Companies  who are shareholders  of the Portfolio  will solicit voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be  liable  for all  obligations of  the Series,  but not  of the  other Series.
However, the  risk of  an investor  in the  Series incurring  financial loss  on
account  of such liability would be limited to circumstances in which the Series
had inadequate  insurance and  was unable  to meet  its obligations  out of  its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.

SHARE PRICES AND NET ASSET VALUE
   
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net  asset  value  ("NAV")  per  share. The  NAVs  for  each  Portfolio  and its
corresponding Series are calculated by subtracting liabilities from total assets
(in the case of the Series, the market value of the securities the Series  holds
plus  cash and other assets; in the case of a Portfolio, its percentage interest
in its  corresponding Series,  multiplied by  the Series'  NAV, plus  any  other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number  of Portfolio shares  outstanding and rounding the  result to the nearest
full cent.
    
   
   The  Government  Income  Portfolio  and  AMT  Government  Income  Investments
calculate  their NAVs as of  the close of regular trading  on The New York Stock
Exchange ("NYSE"), usually 4 p.m. Eastern time.
    
   
   AMT Government Income Investments generally values securities on the basis of
bid quotations from independent pricing services or principal market makers, or,
if quotations are not available, by a method that the trustees of Managers Trust
believe accurately  reflects  fair  value.  AMT  Government  Income  Investments
periodically  verifies valuations  provided by the  pricing services. Short-term
securities with remaining  maturities of less  than 60 days  are valued at  cost
which, when combined with interest earned, approximates market value.
    
 
                                                                              13
<PAGE>
DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   
   The Government Income Portfolio annually distributes substantially all of its
share  of AMT Government  Income Investments' net investment  income (net of the
Portfolio's expenses), net realized capital  gains, and net realized gains  from
foreign currency transactions, if any, normally in February.
    
   
   The Government Income Portfolio offers its shares solely to separate accounts
of  the Life Companies. All dividends and other distributions are distributed to
the separate  accounts  and will  be  automatically invested  in  Trust  shares.
Dividends and other distributions made by the Portfolio to the separate accounts
are  taxable, if  at all, to  the extent  described in the  prospectuses for the
Variable Contracts.
    
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio  is  treated as  a  separate  entity for  Federal  income  tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986,  as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) and net  capital gain (the  excess of net  long-term capital  gain
over  net short-term capital loss) that is distributed to its shareholders. Each
Portfolio intends  to  distribute  all  of  its net  income  and  gains  to  its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service  that  each  Portfolio, as  an  investor  in a  corresponding  Series of
Managers Trust,  will be  deemed to  own a  proportionate share  of the  Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will  be treated as a  separate partnership for Federal  income tax purposes and
will not be a "publicly traded partnership," with the result that none of  those
Series  will  be subject  to  Federal income  tax  (and, instead,  each investor
therein will take into account in  determining its Federal income tax  liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The  foregoing is only a summary of  some of the important Federal income tax
considerations generally affecting  the Portfolios and  their shareholders;  see
the  SAI for a  more detailed discussion. Prospective  shareholders are urged to
consult their tax advisers.

SPECIAL CONSIDERATIONS
   
   The Portfolios serve  as the  underlying investments  for Variable  Contracts
issued  through separate accounts of the Life  Companies which may or may not be
affiliated.  See  "Distribution  and  Redemption   of  Trust  Shares"  in   this
Prospectus.
    
   
   Section  817(h) of the Code imposes  certain diversification standards on the
underlying assets of segregated asset accounts  that fund contracts such as  the
Variable Contracts (that is, the assets of the Series), which are in addition to
the  diversification requirements imposed on the  Portfolios by the 1940 Act and
Subchapter M. Failure to satisfy those  standards would result in imposition  of
Federal  income tax on a Variable Contract owner with respect to the increase in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset account that funds contracts such as the Variable Contracts is treated  as
meeting  the  diversification standards  if, as  of the  close of  each calendar
quarter, the assets in the account  meet the diversification requirements for  a
regulated  investment company and  no more than  55% of those  assets consist of
cash, cash items, U.S. Government  securities and securities of other  regulated
investment companies.
    
   The  Treasury Regulations amplify the  diversification standards set forth in
Section 817(h)  and provide  an alternative  to the  provision described  above.
Under  the  regulations,  an  investment  portfolio  will  be  deemed adequately
diversified if (i)  no more than  55% of the  value of the  total assets of  the
portfolio  is represented by any  one investment; (ii) no  more than 70% of such
value is represented  by any two  investments; (iii)  no more than  80% of  such
value is represented by any three investments; and (iv) no more than 90% of such
value  is represented by any four investments. For purposes of these Regulations
all securities of the same issuer are  treated as a single investment, but  each
United  States  government  agency  or instrumentality  shall  be  treated  as a
separate issuer.
   
   Each Series  will be  managed  with the  intention  of complying  with  these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section  817  of the  Code  and the  Treasury  Regulations thereunder  do not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder  fund structure. As described under  "Tax Status" above, the Trust
and Managers Trust  have received  a ruling  from the  Internal Revenue  Service
concluding  that the "look-through" rule of  Section 817, which would permit the
segregated asset  accounts to  look  through to  the  underlying assets  of  the
Series, will be available for the variable contract diversification test.
    
   Currently,  the State  of California imposes  diversification requirements on
variable insurance products funds investing in non-U.S. securities. Under  these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must  be invested in at least five countries; less than 80% but at least 60%, in
at least four  countries; less  than 60%  but at least  40%, in  at least  three
countries; and less than 40% but at least 20%, in at least two countries, except
that  up to  35% of  a fund's assets  may be  invested in  securities of issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United Kingdom or Germany.  The Trust and Managers  Trust intend to comply  with
the California diversification requirements, to the extent applicable.
 
                                                                              15

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B Management  serves as  the investment  manager of  AMT Government  Income
Investments,  as  administrator  of  the  Government  Income  Portfolio,  and as
distributor of the shares of the Government Income Portfolio. N&B Management and
its predecessor firms have specialized in the management of no-load mutual funds
since 1950. In addition to serving the Series of Managers Trust, N&B  Management
currently  serves as  investment manager or  investment adviser  of other mutual
funds. Neuberger&Berman,  which acts  as sub-adviser  for the  Series and  other
mutual  funds managed  by N&B Management,  also serves as  investment adviser of
three other  investment  companies. These  funds  had aggregate  net  assets  of
approximately $11.9 billion as of December 31, 1995.
    
   
   As  sub-adviser,  Neuberger&Berman furnishes  N&B Management  with investment
recommendations and  research  information without  added  cost to  the  Series.
Neuberger&Berman  is a member firm of the NYSE and other principal exchanges and
acts as the  Series' principal  broker to  the extent a  broker is  used in  the
purchase  and sale of portfolio securities and the sale of covered call options.
Neuberger&Berman and its affiliates, including N&B Management, manage securities
accounts that had approximately $38.7 billion of assets as of December 31, 1995.
All of  the voting  stock of  N&B Management  is owned  by individuals  who  are
general partners of Neuberger&Berman.
    
   
   Theresa A. Havell is a general partner of Neuberger&Berman and a director and
Vice  President of N&B Management. Ms. Havell is the Manager of the Fixed Income
Group of Neuberger&Berman, which she established in 1984. The Fixed Income Group
manages fixed income accounts that had approximately $11.1 billion of assets  as
of  December  31,  1995.  Ms.  Havell has  had  overall  responsibility  for the
activities of the Fixed Income Group since 1984.
    
   
   William H. Cunningham and Theresa A. Havell are primarily responsible for the
day-to-day management of AMT Government  Income Investments. Mr. Cunningham  has
been  primarily responsible for AMT  Government Income Investments since October
1995. Mr. Cunningham has  been a member  of the Fixed  Income Group since  March
1993  a Senior Portfolio Manager in the Fixed Income Group since June 1995 and a
Vice President  of  N&B Management  since  October  1995. From  August  1989  to
February 1993 he was a manager in the Corporate Finance, Merger and Acquisitions
and Capital Markets Groups for a major corporation.
    
   N&B  Management serves as distributor in  connection with the offering of the
Government Income  Portfolio's  shares.  In  connection with  the  sale  of  the
Portfolio's  shares, the Portfolio  has authorized the  distributor to give only
such information and  to make only  such statements and  representations as  are
contained in the Portfolio's Prospectus.
 
16
<PAGE>
The  distributor is  responsible only for  information given  and statements and
representations made in the  Portfolio's Prospectus and  is not responsible  for
any  information given  or any  statements or  representations made  by the Life
Companies or by brokers or salespersons in connection with Variable Contracts.
   
   Neuberger&Berman acts  as  the principal  broker  for AMT  Government  Income
Investments to the extent a broker is used in the purchase and sale of portfolio
securities  and in  the sale  of covered  call options,  and for  those services
receives  brokerage  commissions.  In  effecting  securities  transactions,  AMT
Government  Income Investments seeks  to obtain the best  price and execution of
orders. For more information, see the SAI.
    
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate the  possibility that the  Series will be  adversely affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.
 
          Expenses

   N&B  Management  provides investment  management  services to  AMT Government
Income Investments that  include, among  other things,  making and  implementing
investment decisions and providing facilities and personnel necessary to operate
the  Series. N&B Management  provides administrative services  to the Government
Income Portfolio that  include furnishing similar  facilities and personnel  for
the  Portfolio. With  the Portfolio's consent,  N&B Management  is authorized to
subcontract some of its responsibilities under its administration agreement with
the  Portfolio  to  third  parties.  For  such  administrative  and   investment
management services, N&B Management is paid the following fees:

   The  Government Income Portfolio  bears all expenses  of its operations other
than those borne  by N&B  Management as administrator  of the  Portfolio and  as
distributor  of its shares. AMT Government Income Investments bears all expenses
of its operations other than those borne by N&B Management as investment manager
of the Series. These expenses include, but are not limited to, for the Portfolio
and the Series, legal and accounting fees and compensation for trustees who  are
not  affiliated with N&B Management; for  the Portfolio, transfer agent fees and
the cost of printing  and sending reports and  proxy materials to  shareholders;
and  for the Series, custodial  fees for securities. Any  expenses which are not
directly attributable to a specific Series are allocated on the basis of the net
assets of the respective Series.

          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B Management  has undertaken  to limit  the Government  Income  Portfolio's
expenses  by reimbursing  the Portfolio for  its operating expenses  and its pro
rata share of AMT Government  Income Investments' operating expenses,  including
the compensation of N&B Management, but excluding taxes, interest, extraordinary
expenses,  brokerage commissions  and transaction costs,  that exceed  1% of the
Portfolio's average  daily  net asset  value.  This undertaking  is  subject  to
termination on 60 days' prior written notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses   of  the  Government  Income   Portfolio  and  AMT  Government  Income
Investments and thereby increase total return.
    
 
   
          Transfer and Dividend Paying Agent
    
 
- --------------------------------------------------------------------------------
 
   
   State Street Bank and Trust Company ("State Street"), Boston,  Massachusetts,
acts  as transfer and dividend paying  agent for the Government Income Portfolio
and in so doing performs certain bookkeeping, data processing and administrative
services. All  correspondence  should be  sent  to  State Street  Bank  &  Trust
Company, P.O. Box 1978, Boston, MA 02105. State Street provides similar services
to AMT Government Income Investments as the Series' transfer agent. State Street
also acts as the custodian of and the Portfolios' assets.

DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and  payments under the  Variable Contracts issued  through separate accounts of
the Life Companies which may or may not be affiliated with the Trust. Shares  of
the  Balanced  Portfolio of  the Trust  are also  offered directly  to Qualified
Plans. Shares of the Trust are purchased and redeemed at net asset value.
   The Boards of  Trustees of the  Trust and Managers  Trust have undertaken  to
monitor  the Trust  and Managers Trust,  respectively, for the  existence of any
material irreconcilable conflict between the interests of the Variable  Contract
owners  of the Life  Companies and to  determine what action,  if any, should be
taken in the  event of a  conflict. The  Life Companies and  N&B Management  are
responsible for reporting any potential or existing conflicts to the Boards. Due
to  differences of tax  treatment and other  considerations, it is theoretically
possible that the interests of various Variable Contract owners participating in
the Trust and Managers Trust and  the interests of Qualified Plans investing  in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or  more Life  Company separate accounts  or Qualified Plans  might withdraw its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions will be  effected by  the separate accounts  to meet  obligations
under  the Variable Contracts and by the Qualified Plans. Contract owners do not
deal directly  with the  Trust  with respect  to  acquisition or  redemption  of
shares.  The trustees of the Trust may refuse to sell shares of any Portfolio to
any person, or suspend or terminate the  offering of shares of any Portfolio  if
such  action is required by law or by regulatory authorities having jurisdiction
or is, in the sole discretion of the trustees acting in good faith and in  light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The  Board of Trustees of  the Trust has adopted  a non-fee Distribution Plan
for each Portfolio of the Trust.
   The Distribution Plan recognizes that N&B  Management may use its assets  and
resources,  including its profits from administration  fees paid by a Portfolio,
to pay expenses associated with  the distribution of Portfolio shares.  However,
N&B  Management will  not receive  any separate fees  for such  expenses. To the
extent that any payments  made by a  Portfolio should be  deemed to be  indirect
financing  of any activity primarily intended to result in the sale of shares of
the Portfolio within the  context of Rule  12b-1 under the  1940 Act, then  such
payments shall be deemed to be authorized by the Distribution Plan.
   Under  the Distribution  Plan, the Portfolio  will require  N&B Management to
provide the Trust with quarterly reports  of the amounts expended in  connection
with  financing  any  activity  primarily  intended to  result  in  the  sale of
Portfolio shares,  and the  purpose for  which such  expenditure was  made.  The
Distribution  Plan may be terminated as to a particular Portfolio at any time by
a vote of a majority of the independent trustees of the Trust or by a vote of  a
majority   of  the  outstanding   voting  securities  of   that  Portfolio.  The
Distribution Plan does not require N&B  Management to perform any specific  type
or  level of distribution activities or to  incur any specific level of expenses
for activities  primarily  intended to  result  in the  sale  of shares  of  the
Portfolio.
 
                                                                              19

DESCRIPTION OF INVESTMENTS
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Government  Income  Investments,  as  indicated below,  may  make  the following
investments, among others, individually or  in combination, although the  Series
may  not necessarily buy any or all of the types of securities or use any or all
of the  investment  techniques that  are  described. These  investments  may  be
limited  by the requirements with which the  Series must comply if the Portfolio
is to qualify  as regulated investment  companies for tax  purposes. The use  of
hedging  or other techniques is discretionary and no representation is made that
the risk of AMT Government Income Investments will be reduced by the  techniques
discussed   in  this  section.  For  additional  information  on  the  following
investments and on other types of investments the Series may make, see the SAI.
    
 
    U.S. GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities  are
obligations  of the  U.S.Treasury backed  by the  full faith  and credit  of the
United States. U.S.  Government Agency  securities are issued  or guaranteed  by
U.S.  Government agencies, instrumentalities, or other U.S. Government-sponsored
enterprises, such  as the  Government  National Mortgage  Association  ("GNMA"),
Federal  National  Mortgage  Association ("FNMA"),  Federal  Home  Loan Mortgage
Corporation ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee  Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may  be backed by the  full faith and credit of  the United States, the issuer's
ability to borrow from the U.S.  Treasury, subject to the Treasury's  discretion
in  certain cases,  or only  by the  credit of  the issuer.  U.S. Government and
Agency securities include certain mortgage-backed securities. The market  prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID  SECURITIES. The Series may  invest up to 10%  of its net assets in
securities that are illiquid, in that they cannot be expected to be sold  within
seven  days at  approximately the  price at  which they  are valued.  Due to the
absence of an  active trading market,  the Series may  experience difficulty  in
valuing  or  disposing of  illiquid  securities. N&B  Management  determines the
liquidity of  the  Series' securities,  under  supervision of  the  trustees  of
Managers Trust. Securities which are freely tradeable in their country of origin
or  in their principal market will not be considered illiquid securities even if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally outside the  U.S., including non-U.S.  governments, their  agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated in or indexed to foreign  currencies, which may also be affected  by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective of the  performance of  the underlying  investment. N&B  Management
considers  these factors  in making investments  for the  Series. AMT Government
Income Investments may enter into forward foreign currency contracts or  futures
contracts (agreements to exchange one currency for another at a future date) and
related  options  to manage  currency risks  and  to facilitate  transactions in
foreign securities. Although these contracts can protect the Series from adverse
exchange rate changes, they involve  a risk of loss  if N&B Management fails  to
predict foreign currency values correctly.
   Investments  in foreign securities could be affected by factors generally not
thought to be present in the U.S. Such factors include, but are not limited  to,
varying  custody, brokerage and settlement practices; difficulty in pricing some
foreign securities; less  public information about  issuers of securities;  less
governmental regulation and supervision over issuance and trading of securities;
the  unavailability of financial  information or the  difficulty of interpreting
financial  information  prepared  under   foreign  accounting  standards;   less
liquidity  and more volatility in foreign securities markets; the possibility of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or
 
20
<PAGE>
diplomatic developments; limitations on the movement of funds or other assets of
the Series between different countries;  difficulties in invoking legal  process
abroad  and enforcing contractual  obligations; and the  difficulty of assessing
economic trends  in foreign  countries. Investment  in foreign  securities  also
involves  higher  brokerage  and  custodian  expenses  than  does  investment in
domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve other  risks  which are  not  ordinarily associated  with  investing  in
domestic  securities. These risks include changes in currency exchange rates and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions   applicable  to  such  investments   or  devaluations  of  foreign
currencies. A decline  in the exchange  rate would reduce  the value of  certain
portfolio   securities  irrespective  of  the   performance  of  the  underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and changes in  rates of exchange  with the U.S.  dollar because the  underlying
security  is usually denominated in foreign currency. All of the foregoing risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN CURRENCY TRANSACTIONS.  The Series  may enter  into forward  foreign
currency  exchange  contracts in  order to  protect  against adverse  changes in
future foreign currency  exchange rates, to  facilitate transactions in  foreign
securities  and to  repatriate dividend or  interest income  received in foreign
currencies. The Series may enter  into contracts to purchase foreign  currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends  to purchase. The Series  may also enter into  contracts to sell foreign
currencies to  protect  against a  decline  in  value of  its  foreign  currency
denominated  portfolio  securities due  to  a decline  in  the value  of foreign
currencies against the  U.S. dollar.  Contracts to sell  foreign currency  could
limit  any potential gain which might be realized  by the Series if the value of
the hedged currency increased.
   The Series may also  enter into forward  foreign currency exchange  contracts
for  non-hedging  purposes  when  the investment  adviser  anticipates  that the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated  in that currency do not present attractive investment opportunities
and are not held in the Series.  The Series may also engage in cross-hedging  by
using  forward contracts  in one currency  to hedge against  fluctuations in the
value of  securities  denominated in  a  different currency  if  the  investment
adviser  believes  that  there  is  a pattern  of  correlation  between  the two
currencies.
   If the  Series enters  into  a forward  currency  exchange contract  to  sell
foreign  currency, it may  be required to  place cash or  high grade liquid debt
securities in  a segregated  account in  an amount  equal to  the value  of  the
Series'  total assets  committed to  the consummation  of the  forward contract.
Although these contracts  can protect  the Series from  adverse exchange  rates,
they  involve risk of loss  if N&B Management fails  to predict foreign currency
values correctly.
 
    PUT AND CALL OPTIONS, FUTURES  CONTRACTS, OPTIONS ON FUTURES CONTRACTS.  The
Series  may  try to  reduce  the risk  of  securities price  changes  (hedge) or
generate income by  writing (selling)  covered call  options against  securities
held  in its portfolio having a market value not exceeding 10% of its net assets
and may purchase call options in related closing transactions. The purchaser  of
a  call option acquires the  right to buy a portfolio  security at a fixed price
during a  specified period.  The maximum  price the  seller may  realize on  the
security  during the option period  is the fixed price.  The seller continues to
bear the  risk of  a decline  in the  security's price,  although this  risk  is
reduced by the premium received for the option.
   The  Series also may  try to manage  portfolio duration by  (1) entering into
interest-rate futures contracts traded on  futures exchanges and (2)  purchasing
and writing options on futures contracts.
 
                                                                              21
<PAGE>
   
   The  Series also may try  to reduce the risk  of securities price changes and
expected changes in  prevailing currency  exchange rates (hedge)  and may  write
covered  call  options  and  purchase  put options  on  debt  securities  in its
portfolio or on foreign  currencies for hedging purposes  or for the purpose  of
producing  income. The Series will write call  options on a security or currency
only if  it holds  that security  or currency  or has  the right  to obtain  the
security  or currency at no additional  cost. These investment practices involve
certain risks,  including transactional  expense, price  volatility and  a  high
degree  of leverage. The Series may  engage in transactions in futures contracts
and related options only  as permitted by regulations  of the Commodity  Futures
Trading Commission.
    
   
   The  writing and purchasing of options is a highly specialized activity which
involves investment techniques  and risks different  from those associated  with
ordinary  portfolio  securities  transactions  including  transactional expense,
price volatility and  a high degree  of leverage. The  writing of options  could
result in significant increases in the Series' turnover rate.
    
   The  primary  risks in  using put  and call  options, futures  contracts, and
options on futures contracts, and forward foreign currency contracts or  options
on  foreign currencies ("Hedging Instruments")  are (1) imperfect correlation or
no correlation between  changes in market  value of the  securities held by  the
Series  and the prices of the Hedging Instruments; (2) possible lack of a liquid
secondary market for Hedging  Instruments and the  resulting inability to  close
out  a Hedging Instrument when  desired; (3) the fact  that the skills needed to
use Hedging Instruments are  different from those needed  to select the  Series'
securities;  (4) the  fact that, although  use of these  instruments for hedging
purposes can reduce the risk of loss,  they also can reduce the opportunity  for
gain,  or  even result  in losses,  by offsetting  favorable price  movements in
hedged investments; and (5) the possible inability of the Series to purchase  or
sell  a security at a time that would otherwise be favorable for it to do so, or
the possible need for the Series to  sell a security at a disadvantageous  time,
due  to its need  to maintain "cover"  or to segregate  securities in connection
with its use of these instruments. Futures, options and forward foreign currency
contracts are considered derivatives.
   
    FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or  forward
commitment  transaction, the Series  commits to purchase  securities in order to
secure an advantageous price and  yield at the time  of the commitment and  pays
for  the securities when they  are delivered at a  future date (generally within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity to obtain  a favorable  price and yield.  When-issued securities  or
securities  subject to  a forward  commitment may  decline or  increase in value
during the period from  the Series' investment commitment  to the settlement  of
the purchase which may magnify fluctuation in the Series' NAV.
    
 
    INDEXED  SECURITIES. The Series may invest in indexed securities whose value
is  linked  to  currencies,  interest  rates,  commodities,  indices,  or  other
financial  indicators.  Most indexed  securities are  short-to-intermediate term
fixed-income securities whose values at maturity or interest rates rise or  fall
according to the change in one or more specified underlying instruments. Indexed
securities  may  be  positively or  negatively  indexed (i.e.,  their  value may
increase or decrease  if the  underlying instrument appreciates),  and may  have
return   characteristics  similar  to  direct   investments  in  the  underlying
instrument or  to one  or more  options on  the underlying  instrument.  Indexed
securities may be more volatile than the underlying instrument itself.
 
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements  and lend securities  from its portfolio.  In a repurchase agreement,
the Series buys a security  from a Federal Reserve  member bank or a  securities
dealer  and  simultaneously agrees  to  sell it  back at  a  higher price,  at a
specified date, usually less than a  week later. The underlying securities  must
fall within the Series' investment policies and limitations (but not limitations
as  to maturity or duration).  The Series also may  lend portfolio securities to
banks, brokerage firms, or institutional
 
22
<PAGE>
investors to earn income.  Costs, delays or losses  could result if the  selling
party  to a repurchase agreement or the borrower of portfolio securities becomes
bankrupt or otherwise defaults. N&B Management monitors the creditworthiness  of
sellers and borrowers.
 
    REVERSE  REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.  In a  reverse repurchase
agreement, the Series sells securities to a bank or securities dealer and at the
same time agrees to repurchase  the same securities at a  later date at a  fixed
price.  During the period before the repurchase, the Series continues to receive
principal and interest payments on the securities. In a dollar roll, the  Series
sells  securities for delivery in the current month and simultaneously contracts
to repurchase  substantially similar  (same  type and  coupon) securities  on  a
specified  future  date  from  the  same party.  During  the  period  before the
repurchase,  the  Series  forgoes  principal   and  interest  payments  on   the
securities.  The Series  is compensated  by the  difference between  the current
sales price and the forward price for the future purchase (often referred to  as
the  "drop"), as  well as  by the interest  earned on  the cash  proceeds of the
initial sale. Reverse repurchase  agreements and dollar  rolls may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements and dollar rolls.
 
    MORTGAGE-BACKED SECURITIES. Mortgage-backed  securities represent  interests
in,  or are  secured by  and payable  from, pools  of mortgage  loans, including
collateralized mortgage  obligations. These  securities may  be U.S.  Government
mortgage-backed  securities, which are issued or guaranteed by a U.S. Government
agency or instrumentality (though not necessarily  backed by the full faith  and
credit  of the United States), such as  GNMA, FNMA and FHLMC certificates. Other
mortgage-backed securities are issued by private issuers, generally  originators
of  and investors  in mortgage  loans, including  savings associations, mortgage
bankers, commercial  banks, investment  bankers, and  special purpose  entities.
These  private mortgage-backed  securities may  be supported  by U.S. Government
mortgage-backed securities or  some form of  non-government credit  enhancement.
Mortgage-backed  securities may have either  fixed or adjustable interest rates.
Tax or regulatory changes may  adversely affect the mortgage securities  market.
In  addition, changes in  the market's perception  of the issuer  may affect the
value of  mortgage-backed  securities. The  rate  of return  on  mortgage-backed
securities  may be affected by prepayments of principal on the underlying loans,
which generally increase as interest rates  decline; as a result, when  interest
rates  decline,  holders  of  these  securities  normally  do  not  benefit from
appreciation in market value to the same extent as holders of other non-callable
debt securities. N&B Management  determines the effective  life and duration  of
mortgage-backed  securities  based  on  industry  practice  and  current  market
conditions. If N&B Management's determination is  not borne out in practice,  it
could  positively  or negatively  affect  the value  of  the Series  when market
interest rates change.  Increasing market  interest rates  generally extend  the
effective maturities of mortgage-backed securities.
 
    ASSET-BACKED  SECURITIES. Asset-backed securities represent interests in, or
are secured  by  and payable  from  pools of  assets,  such as  consumer  loans,
CARS-SM-  ("Certificates  for Automobile  Receivables"), credit  card receivable
securities, and installment  loan contracts.  Although these  securities may  be
supported by letters of credit or other credit enhancements, payment of interest
and  principal ultimately depends upon  individuals paying the underlying loans.
The risk  that  recovery on  repossessed  collateral might  be  unavailable,  or
inadequate to support payments on asset-backed securities is greater than in the
case of mortgage-backed securities.
 
    SWAP  AGREEMENTS. To help enhance  the value of its  portfolio or manage its
exposure to different types of investments,  the Series may enter into  interest
rate,  currency, and mortgage swap agreements and may purchase and sell interest
rate "caps," "floors," and "collars."
 
                                                                              23
<PAGE>
   In a typical interest rate swap  agreement, one party agrees to make  regular
payments  equal to a floating interest rate on a specified amount (the "notional
principal amount") in return for payments equal to a fixed interest rate on  the
same  amount for a specified period. If a swap agreement provides for payment in
different currencies,  the  parties may  also  agree to  exchange  the  notional
principal  amount. Mortgage  swap agreements are  similar to  interest rate swap
agreements, except the notional principal amount is tied to a reference pool  of
mortgages.
   In  a cap or  floor, one party agrees,  usually in return for  a fee, to make
payments under  particular  circumstances.  For example,  the  purchaser  of  an
interest  rate cap has the  right to receive payments  to the extent a specified
interest rate exceeds an agreed level;  the purchaser of an interest rate  floor
has  the right to receive payments to the extent a specified interest rate falls
below an agreed level.  A collar entitles the  purchaser to receive payments  to
the extent a specified interest rate falls outside an agreed range.
   Swap  agreements, including caps and floors,  may involve leverage and may be
highly volatile; depending on  how they are used,  they may have a  considerable
impact  on the Series' performance. Swap agreements involve risks depending upon
the other  party's creditworthiness  and  ability to  perform,  as well  as  the
Series'  ability to terminate its swap agreements or reduce its exposure through
offsetting transactions. Swap  agreements may  be illiquid. The  swap market  is
relatively  new  and  is  largely  unregulated.  Swap  agreements  are generally
considered "derivatives."
 
    VARIABLE AND FLOATING RATE SECURITIES. Variable and floating rate securities
have interest  rate adjustment  formulas  that help  to stabilize  their  market
value. Many of these instruments carry a demand feature which permits the Series
to sell them during a determined time period at par value plus accrued interest.
The  demand feature is often backed by a  credit instrument, such as a letter of
credit, or by a creditworthy insurer. The Series may rely on such instrument  or
the  creditworthiness of the  insurer in purchasing a  variable or floating rate
security.
 
    ZERO  COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay   interest
currently;  instead, they are sold  at a discount from  their face value and are
redeemed at face value when  they mature. Because zero  coupon bonds do not  pay
current income, their prices can be very volatile when interest rates change. In
calculating  its daily  income, the Series  accrues a portion  of the difference
between a zero coupon bond's purchase price and its face value.
 
    RESTRICTED SECURITIES AND  RULE 144A  SECURITIES. The Series  may invest  in
restricted  securities and Rule 144A securities. Restricted securities cannot be
sold to the public without registration under the Securities Act of 1933  ("1933
Act").  Unless  registered  for  sale,  these securities  can  be  sold  only in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted securities are generally  considered illiquid. Rule 144A  securities,
although not registered, may be resold only to qualified institutional buyers in
accordance  with Rule 144A under the  1933 Act. Unregistered securities may also
be sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B  Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.

- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of one of the  Portfolios
are  also offered directly to qualified pension and retirement plans ("Qualified
Plans").

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and  limitations  that  are  identical  to  those  of  the  respective
Portfolio.  The trustees  of the  Trust believe  that this  "master/feeder fund"
structure may benefit shareholders. For more information about the  organization
of   the  Portfolios  and   the  Series,  including   certain  features  of  the
master/feeder fund structure, see  "Special Information Regarding  Organization,
Capitalization, and Other Matters" on page 10. For more details about AMT Growth
Investments,  its investments and their risks,  see "Investment Program" on page
7, "Ratings of Securities" on page 8, "Borrowings" on page 8 , and  "Description
of Investments" on page 20.
    
   Here  is a  summary of  important features  of the  Growth Portfolio  and its
corresponding Series. Of course,  there can be no  assurance that the  Portfolio
will meet its investment objective.

          Risk Factors

   An  investment in  any Portfolio involves  certain risks,  depending upon the
types of  investments made  by its  corresponding Series.  Special risk  factors
apply  to investments  which may  be made by  AMT Growth  Investments in foreign
securities, options and futures contracts and zero coupon bonds.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B Management,  with  the  assistance of  Neuberger&Berman  as  sub-adviser,
selects  investments for  AMT Growth  Investments. N&B  Management also provides
administrative services to AMT Growth  Investments and the Growth Portfolio  and
acts  as  distributor  of  the  shares of  the  Portfolio.  See  "Management and
Administration" in this Prospectus.
    
 
          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   
   AMT  Growth  Investments  is  managed  using  a  growth-oriented   investment
approach. This approach seeks out stocks of companies that are projected to grow
at  above-average  rates  and may  appear  poised  for a  period  of accelerated
earnings.
    
   
   The growth portfolio manager is  willing to pay a  higher share price in  the
hope  that the stock's earnings momentum will carry the stock's price higher. As
a stock's price increases based on  strong earnings, the stock's original  price
appears  low in  relation to  the growth  rate of  its earnings.  Sometimes this
happens when a particular company or  industry is temporarily out of favor  with
the  market or under-researched. This strategy is called "growth at a reasonable
price."
    
 
                                                                               3
<PAGE>
   
   In general,  AMT Growth  Investments  places a  greater emphasis  on  finding
securities whose measures of fundamental value are low in relation to the growth
rate  of their  future earnings  and cash  flow, as  projected by  the portfolio
manager, and AMT Growth Investments is therefore willing to invest in securities
with prices that are somewhat higher multiples of earnings.
    
   
   While this approach has resulted in  solid returns over the long term,  there
can  be no assurance that these results will be achieved in the future. For more
information, see "Performance Information" in this Prospectus.

  NOTES:
   
1)The  per share amounts which are shown have been computed based on the average
  number of shares outstanding during each year.
    
   
2)The per share amounts and ratios which are shown reflect income and  expenses,
  including  the  Portfolio's  proportionate  share of  the  Series'  income and
  expenses.
    
   
3)The Portfolio transferred all of its investment securities into its Series  on
  April  28, 1995. After that date the Portfolio invested only in its Series and
  that Series, rather  than the Portfolio,  engaged in securities  transactions.
  Therefore,  after that date the Portfolio  had no portfolio turnover rate. The
  portfolio turnover rate for AMT Growth Investments for the period from May  1,
  1995 to December 31, 1995 was 35%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in  net asset value  on the performance  of the Portfolio  during each year and
 assumes dividends  and capital  gain distributions,  if any,  were  reinvested.
 Results  represent  past  performance  and  do  not  guarantee  future results.
 Investment returns and principal may fluctuate and shares when redeemed may  be
 worth  more or less than original cost. The total return information shown does
 not reflect  expenses  that  apply  to the  separate  account  or  the  related
 insurance  policies,  and inclusion  of these  charges  would reduce  the total
 return figures for all periods shown.

INVESTMENT PROGRAM
   
   The  investment  policies and  limitations of  the  Growth Portfolio  and AMT
Growth Investments  are identical.  The  Growth Portfolio  invests only  in  AMT
Growth  Investments. Therefore, the following shows  you the kinds of securities
in which AMT  Growth Investments invests.  For an explanation  of some types  of
investments, see "Description of Investments" on page 20.
    
   Investment  policies and limitations  of the Growth  Portfolio and AMT Growth
Investments are not fundamental unless otherwise specified in this Prospectus or
the SAI. While  a non-fundamental  policy or limitation  may be  changed by  the
trustees  of the  Trust or of  Managers Trust without  shareholder approval, the
Growth Portfolio  intends  to notify  shareholders  before making  any  material
change to such policies or limitations. Fundamental policies and limitations may
not  be changed without shareholder approval. There can be no assurance that AMT
Growth Investments and the Growth  Portfolio will achieve their objectives.  The
Growth  Portfolio,  by itself,  does  not represent  a  comprehensive investment
program.
   
   Additional investment techniques,  features, and  limitations concerning  AMT
Growth Investments' investment program are described in the SAI.
    
 
          AMT Growth Investments
 
- --------------------------------------------------------------------------------
 
   The  investment objective of AMT Growth  Investments and the Growth Portfolio
is to  seek  capital appreciation  without  regard to  income.  This  investment
objective  is fundamental  and may  not be changed  without the  approval of the
holders of a majority of the outstanding shares of the Portfolio and Series.
   AMT Growth Investments generally invests  in securities believed to have  the
maximum potential for long-term capital appreciation. It does not seek to invest
in securities that pay dividends or interest, and any such income is incidental.
The  Series  expects to  be almost  fully  invested in  common stocks,  often of
companies that may be temporarily out of favor in the market.
   
   The Series' aggressive growth investment  program involves greater risks  and
share   price  volatility  than  programs   that  invest  in  more  conservative
securities. Moreover, the Series does not follow a policy of active trading  for
short-term  profits.  Accordingly,  the  Series  may  be  more  appropriate  for
investors with  a longer-range  perspective.  The Series  uses  a "growth  at  a
reasonable  price"  investment  approach.  When  N&B  Management  believes  that
particular securities have greater potential for long-term capital appreciation,
the Series  may purchase  such securities  at prices  with higher  multiples  to
measures of economic value (such as earnings or cash flow) than other Series. In
addition,  the  Series  focuses  on companies  with  strong  balance  sheets and
reasonable valuations relative to  their growth rates.  It also diversifies  its
investments into many companies and industries.
    
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   While  AMT Growth Investments does not purchase securities with the intention
of profiting from short-term trading, it may sell portfolio securities prior  to
maturity when the investment adviser believes that such action is advisable.
   
   The  portfolio  turnover  rates  for  the  Growth  Portfolio  and  AMT Growth
Investments, and for  the predecessor  of the  Growth Portfolio  for the  period
prior  to  May 1,  1995,  are set  forth  under "Financial  Highlights"  in this
Prospectus. It is  anticipated that the  annual portfolio turnover  rate of  AMT
Growth Investments in some fiscal years may exceed 100%.
    
 
                                                                               7
<PAGE>
   
   Turnover  rates in excess of 100% may result in higher costs (which are borne
directly by the Series) and a possible increase in short-term capital gains  (or
losses).
    
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
    HIGH  QUALITY DEBT SECURITIES.  High quality debt  securities are securities
that have received a rating from at least one nationally recognized  statistical
rating  organization ("NRSRO"), such as Standard  & Poor's Ratings Group ("S&P")
or Moody's Investors Service, Inc. ("Moody's"), in one of the two highest rating
categories (the highest  category in the  case of commercial  paper) or, if  not
rated  by any NRSRO,  such as U.S.  Government and Agency  securities, have been
determined by N&B Management to be of comparable quality.
 
   
    INVESTMENT GRADE  DEBT SECURITIES.  "Investment grade"  debt securities  are
those  receiving one of the  four highest ratings from  Moody's, S&P, or another
NRSRO or, if unrated by any NRSRO,  deemed comparable by N&B Management to  such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's  deems securities  rated in  its fourth  highest category  (Baa) to have
speculative characteristics;  a  change in  economic  factors could  lead  to  a
weakened capacity of the issuer to repay.
    
   If  the quality of securities held  by AMT Growth Investments deteriorates so
that the  securities would  no longer  satisfy its  standards, the  Series  will
engage  in an  orderly disposition  of the  downgraded securities  to the extent
necessary to ensure that the Series' holdings of such securities will not exceed
5% of the Series' net assets.
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT Growth Investments has a fundamental policy that it may not borrow money,
except that  it may  (1) borrow  money  from banks  for temporary  or  emergency
purposes  and  not  for leveraging  or  investment  and (2)  enter  into reverse
repurchase agreements  for any  purpose,  so long  as  the aggregate  amount  of
borrowings  and reverse repurchase  agreements does not  exceed one-third of the
Series' total assets  (including the  amount borrowed)  less liabilities  (other
than   borrowings).  The  Series   does  not  expect  to   borrow  money.  As  a
non-fundamental policy,  the Series  may purchase  portfolio securities  if  its
outstanding  borrowings, including  reverse repurchase agreements,  exceed 5% of
its total assets.
   Currently, the State of California imposes borrowing limitations on  variable
insurance  product funds.  To comply with  these limitations, each  Series, as a
matter of operating policy, has undertaken that it will not borrow more than 10%
of its net  asset value  when borrowing  for any  general purpose  and will  not
borrow  more  than 25%  of its  net asset  value when  borrowing as  a temporary
measure to facilitate redemptions.  For these purposes, net  asset value is  the
market  value of all investments or assets owned less outstanding liabilities at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For temporary defensive  purposes, AMT  Growth Investments may  invest up  to
100%  of its  total assets  in cash  and cash  equivalents, U.S.  Government and
Agency Securities, commercial paper and certain other money market  instruments,
as well as repurchase agreements collateralized by the foregoing.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.

PERFORMANCE INFORMATION
   Performance  information for the Growth Portfolio  may be presented from time
to time  in advertisements  and  sales literature.  The Portfolio's  "yield"  is
calculated by dividing the Portfolio's annualized net investment income during a
recent  30-day period by the Portfolio's net asset  value on the last day of the
period. A  Portfolio's total  return  is quoted  for  the one-year  period,  the
five-year  period and ten-year  period through the  most recent calendar quarter
and is determined by  calculating the change in  value of a hypothetical  $1,000
investment in the Portfolio for each of those periods. Total return calculations
assume  reinvestment  of  all  Portfolio dividends  and  distributions  from net
investment income and net realized gains, respectively.
   All performance  information presented  for the  Portfolio is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life  Company separate accounts  investing in the Portfolio
which will take into account  insurance-related charges and expenses under  such
insurance  policies and contracts. Further information regarding the Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of one  or more  Portfolios to various  indices. Advertisements  may
also  contain  the performance  rankings  assigned certain  Portfolios  or their
advisers by various publications and statistical services. Any such  comparisons
or  rankings  are based  on past  performance  and the  statistical computations
performed by publications and services,  and are not necessarily indications  of
future  performance.  Because  the  Portfolio is  a  managed  investment vehicle
investing in a wide variety of securities, the securities owned by the Portfolio
will not match those making  up an index. Please note  that indices do not  take
into  account any  fees and expenses  of investing in  the individual securities
that they track and that individuals cannot invest in any index.
 
                                                                               9

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  one Portfolio which as of December 31, 1995 had not yet commenced investment
operations.  These  conversions  were  approved  by  the  shareholders  of   the
predecessors of the Portfolios in August 1994. Each Portfolio invests all of its
net  investable assets  in its  corresponding Series,  in each  case receiving a
beneficial interest in  that Series.  The trustees  of the  Trust may  establish
additional   portfolios  or   classes  of   shares,  without   the  approval  of
shareholders. The assets of  each Portfolio belong only  to that Portfolio,  and
the  liabilities of  each Portfolio  are borne solely  by that  Portfolio and no
other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International Portfolio which  as of  December 31,  1995 had  not yet  commenced
investment   operations)   invested   all   of   its   net   investable   assets
    
 
10
<PAGE>
   
(cash, securities, and  receivables relating to  securities) in a  corresponding
Series  of Managers Trust,  receiving a beneficial interest  in that Series. The
assets of each Series belong  only to that Series,  and the liabilities of  each
Series are borne solely by that Series and no other.
    
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor in a Series other than a Portfolio redeemed its interest in the Series,
the  Series' remaining investors  (including the Portfolio)  might, as a result,
experience higher pro rata operating expenses, thereby producing lower returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a Portfolio withdrew its investment from a Series, the trustees  would
consider  what action  might be  taken, including the  investment of  all of the
Portfolio's net investable  assets in  another pooled  investment entity  having
substantially the same investment objective as the Portfolio or the retention by
the  Portfolio of its own investment manager  to manage its assets in accordance
with its investment objective, policies,  and limitations. The inability of  the
Portfolio  to find  a suitable  replacement could  have a  significant impact on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors except as required by the 1940 Act. Each investor in a Series will  be
entitled  to  vote in  proportion  to its  relative  beneficial interest  in the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act and  other  applicable  law,  a Portfolio  will  solicit  proxies  from  its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
                                                                              11
<PAGE>
Portfolio's  shareholders. Pursuant to current  interpretations of the 1940 Act,
the Life Companies  who are shareholders  of the Portfolio  will solicit  voting
instructions from contract owners with respect to any matters that are presented
to  a vote of Portfolio shareholders. If  there are other investors in a Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN  PROVISIONS. Each investor in a  Series, including a Portfolio, will
be liable  for all  obligations of  the Series,  but not  of the  other  Series.
However, the risk of an investor in a Series incurring financial loss on account
of  such liability  would be  limited to circumstances  in which  the Series had
inadequate insurance and was unable to  meet its obligations out of its  assets.
Upon  liquidation of a Series, investors would  be entitled to share pro rata in
the net assets of the Series available for distribution to investors.

SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net asset  value  ("NAV")  per  share.  The NAVs  for  each  Portfolio  and  its
corresponding Series are calculated by subtracting liabilities from total assets
(in  the case of a  Series, the market value of  the securities the Series holds
plus cash and other assets; in the case of a Portfolio, its percentage  interest
in  its  corresponding Series,  multiplied by  the Series'  NAV, plus  any other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number of Portfolio shares  outstanding and rounding the  result to the  nearest
full cent.
   The  Growth Portfolio and  AMT Growth Investments calculate  their NAVs as of
the close of regular trading on The New York Stock Exchange ("NYSE"), usually  4
p.m. Eastern time.
   AMT  Growth  Investments  values its  equity  securities  (including options)
listed on the NYSE,  the American Stock Exchange,  other national exchanges,  or
the  NASDAQ market, and other securities for which market quotations are readily
available, at the latest sale price on the day NAV is calculated. If there is no
sale of such a security on that day, that security is valued at the mean between
its closing  bid and  asked  prices. AMT  Growth  Investments values  all  other
securities  and assets,  including restricted securities,  by a  method that the
trustees of Managers Trust believe accurately reflects fair value.
 
                                                                              13
<PAGE>
DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   
   The  Growth Portfolio annually distributes substantially  all of its share of
AMT Growth Investments' net investment income (net of the Portfolio's expenses),
net realized  capital  gains,  and  net realized  gains  from  foreign  currency
transactions, if any, normally in February.
    
   The  Growth Portfolio  offers its shares  solely to separate  accounts of the
Life Companies. All  dividends and  other distributions are  distributed to  the
separate  accounts and will  be automatically invested  in shares. Dividends and
other distributions made by the Portfolio to the separate accounts are  taxable,
if  at  all,  to the  extent  described  in the  prospectuses  for  the Variable
Contracts.
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio  is  treated as  a  separate  entity for  Federal  income  tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986,  as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) and net  capital gain (the  excess of net  long-term capital  gain
over  net short-term capital loss) that is distributed to its shareholders. Each
Portfolio intends  to  distribute  all  of  its net  income  and  gains  to  its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service  that  each  Portfolio, as  an  investor  in a  corresponding  Series of
Managers Trust,  will be  deemed to  own a  proportionate share  of the  Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will  be treated as a  separate partnership for Federal  income tax purposes and
will not be a "publicly traded partnership," with the result that none of  those
Series  will  be subject  to  Federal income  tax  (and, instead,  each investor
therein will take into account in  determining its Federal income tax  liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The  foregoing is only a summary of  some of the important Federal income tax
considerations generally affecting  the Portfolios and  their shareholders;  see
the  SAI for a  more detailed discussion. Prospective  shareholders are urged to
consult their tax advisers.

<PAGE>
SPECIAL CONSIDERATIONS
   
   The Portfolios serve  as the  underlying investments  for Variable  Contracts
issued  through separate accounts of the Life  Companies which may or may not be
affiliated.  See  "Distribution  and  Redemption   of  Trust  Shares"  in   this
Prospectus.
    
   
   Section  817(h) of the Code imposes  certain diversification standards on the
underlying assets of segregated asset accounts  that fund contracts such as  the
Variable Contracts (that is, the assets of the Series), which are in addition to
the  diversification requirements imposed on the  Portfolios by the 1940 Act and
Subchapter M. Failure to satisfy those  standards would result in imposition  of
Federal  income tax on a Variable Contract owner with respect to the increase in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset account that funds contracts such as the Variable Contracts is treated  as
meeting  the  diversification standards  if, as  of the  close of  each calendar
quarter, the assets in the account  meet the diversification requirements for  a
regulated  investment company and  no more than  55% of those  assets consist of
cash, cash items, U.S. Government  securities and securities of other  regulated
investment companies.
    
   The  Treasury Regulations amplify the  diversification standards set forth in
Section 817(h)  and provide  an alternative  to the  provision described  above.
Under  the  regulations,  an  investment  portfolio  will  be  deemed adequately
diversified if (i)  no more than  55% of the  value of the  total assets of  the
portfolio  is represented by any  one investment; (ii) no  more than 70% of such
value is represented  by any two  investments; (iii)  no more than  80% of  such
value is represented by any three investments; and (iv) no more than 90% of such
value  is represented by any four investments. For purposes of these Regulations
all securities of the same issuer are  treated as a single investment, but  each
United  States  government  agency  or instrumentality  shall  be  treated  as a
separate issuer.
   
   Each Series  will be  managed  with the  intention  of complying  with  these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section  817  of the  Code  and the  Treasury  Regulations thereunder  do not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder  fund structure. As described under  "Tax Status" above, the Trust
and Managers Trust  have received  a ruling  from the  Internal Revenue  Service
concluding  that the "look-through" rule of  Section 817, which would permit the
segregated asset  accounts to  look  through to  the  underlying assets  of  the
Series, will be available for the variable contract diversification test.
    
   Currently,  the State  of California imposes  diversification requirements on
variable insurance products funds investing in non-U.S. securities. Under  these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must  be invested in at least five countries; less than 80% but at least 60%, in
at least four  countries; less  than 60%  but at least  40%, in  at least  three
countries; and less than 40% but at least 20%, in at least two countries, except
that  up to  35% of  a fund's assets  may be  invested in  securities of issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United Kingdom or Germany.  The Trust and Managers  Trust intend to comply  with
the California diversification requirements, to the extent applicable.
 
                                                                              15

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B Management serves as the investment manager of AMT Growth Investments, as
administrator of the Growth Portfolio, and  as distributor of the shares of  the
Growth  Portfolio. N&B Management and its  predecessor firms have specialized in
the management of no-load  mutual funds since 1950.  In addition to serving  the
Series  of Managers Trust, N&B Management currently serves as investment manager
or investment adviser  of other  mutual funds. Neuberger&Berman,  which acts  as
sub-adviser  for the  Series and other  mutual funds managed  by N&B Management,
also serves as  investment adviser  of three other  investment companies.  These
funds had aggregate net assets of approximately $11.9 billion as of December 31,
1995.
    
   
   As  sub-adviser,  Neuberger&Berman furnishes  N&B Management  with investment
recommendations and  research  information without  added  cost to  the  Series.
Neuberger&Berman  is a member firm of the NYSE and other principal exchanges and
acts as  the Series'  principal broker  in the  purchase and  sale of  portfolio
securities  and  the  sale of  covered  call options.  Neuberger&Berman  and its
affiliates, including  N&B  Management,  manage  securities  accounts  that  had
approximately $38.7 billion of assets as of December 31, 1995. All of the voting
stock  of N&B  Management is  owned by individuals  who are  general partners of
Neuberger&Berman.
    
   
   Mark R.  Goldstein  and  Susan  Switzer are  primarily  responsible  for  the
day-to-day  management  of  AMT  Growth Investments.  Mr.  Goldstein  is  a Vice
President of N&B Management  and a general partner  of Neuberger&Berman. He  has
had  primary  responsibility  for  AMT  Growth  Investments  since  April  1993.
Previously he was  a securities analyst  and portfolio manager  with that  firm.
Susan Switzer has been an Assistant Vice President of N&B Management since March
1995,  and a portfolio manager for  Neuberger&Berman since January 1995. She has
had primary responsibility for  AMT Growth Investments  since January 1995.  Ms.
Switzer was a research analyst and assistant portfolio manager for another money
management firm from 1989 to 1994.
    
   
   N&B  Management serves as distributor in  connection with the offering of the
Growth Portfolio's  shares.  In connection  with  the sale  of  the  Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information and  to  make  only  such  statements  and  representations  as  are
contained  in the representations made in  the Portfolio's Prospectus and is not
responsible for any information given or any statements or representations  made
by  the Life Companies or by brokers or salespersons in connection with Variable
Contracts.

<PAGE>
   Neuberger&Berman acts as the principal  broker for AMT Growth Investments  in
the  purchase and sale of  portfolio securities and in  the sale of covered call
options, and for  those services  receives brokerage  commissions. In  effecting
securities  transactions, AMT Growth Investments seeks  to obtain the best price
and execution of orders. For more information, see the SAI.
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate  the possibility  that a  Series will  be adversely  affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.
 
          Expenses
 
- --------------------------------------------------------------------------------
 
   N&B   Management  provides  investment  management  services  to  AMT  Growth
Investments that include, among other things, making and implementing investment
decisions and  providing  facilities  and personnel  necessary  to  operate  the
Series.  N&B Management provides administrative services to the Growth Portfolio
that include furnishing similar facilities and personnel for the Portfolio. With
the Portfolio's consent, N&B Management is authorized to subcontract some of its
responsibilities under its administration agreement with the Portfolio to  third
parties.  For  such  administrative  and  investment  management  services,  N&B
Management is paid the following fees:

   The Growth Portfolio bears  all expenses of its  operations other than  those
borne  by N&B Management as administrator of the Portfolio and as distributor of
its shares. AMT Growth  Investments bears all expenses  of its operations  other
than  those borne by N&B  Management as investment manager  of the Series. These
expenses include, but  are not  limited to, for  the Portfolio  and the  Series,
legal  and accounting fees and compensation  for trustees who are not affiliated
with N&B Management;  for the  Portfolio, transfer agent  fees and  the cost  of
printing  and sending reports  and proxy materials to  shareholders; and for the
Series, custodial  fees for  securities.  Any expenses  which are  not  directly
attributable  to a specific Series are allocated  on the basis of the net assets
of the respective Series.
    
 
                                                                              17

          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B Management has  undertaken to  limit the Growth  Portfolio's expenses  by
reimbursing  the Portfolio for its operating expenses  and its pro rata share of
AMT Growth Investments'  operating expenses, excluding  the compensation of  N&B
Management,  taxes, interest, extraordinary  expenses, brokerage commissions and
transaction costs, that exceed  1% of the Growth  Portfolio's average daily  net
asset  value.  This undertaking  is  subject to  termination  on 60  days' prior
written notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses of the Portfolio and the Series and thereby increase total return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State Street Bank and Trust Company ("State Street"), Boston,  Massachusetts,
acts  as transfer and dividend  paying agent for the  Growth Portfolio and in so
doing performs certain bookkeeping, data processing and administrative services.
All correspondence should be sent to State Street Bank & Trust Company, P.O. Box
1978, Boston, MA  02105. State Street  provides similar services  to AMT  Growth
Investments  as  the  Series' transfer  agent.  State  Street also  acts  as the
custodian of the Series' and the Portfolio's assets.

<PAGE>
DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   
   Shares of the Trust are issued and redeemed in connection with investments in
and payments under the  Variable Contracts issued  through separate accounts  of
the  Life Companies which may or may not be affiliated with the Trust. Shares of
one Portfolio of the Trust are also offered directly to Qualified Plans.  Shares
of the Trust are purchased and redeemed at net asset value.
    
   The  Boards of Trustees  of the Trust  and Managers Trust  have undertaken to
monitor the Trust  and Managers Trust,  respectively, for the  existence of  any
material  irreconcilable conflict between the interests of the Variable Contract
owners of the Life  Companies and to  determine what action,  if any, should  be
taken  in the  event of a  conflict. The  Life Companies and  N&B Management are
responsible for reporting any potential or existing conflicts to the Boards. Due
to differences of tax  treatment and other  considerations, it is  theoretically
possible that the interests of various Variable Contract owners participating in
the  Trust and Managers Trust and the  interests of Qualified Plans investing in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or more Life  Company separate accounts  or Qualified Plans  might withdraw  its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions  will be  effected by the  separate accounts  to meet obligations
under the Variable Contracts and by the Qualified Plans. Contract owners do  not
deal  directly  with the  Trust  with respect  to  acquisition or  redemption of
shares. The trustees of the Trust may refuse to sell shares of any Portfolio  to
any  person, or suspend or terminate the  offering of shares of any Portfolio if
such action is required by law or by regulatory authorities having  jurisdiction
or  is, in the sole discretion of the trustees acting in good faith and in light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The Board of Trustees  of the Trust has  adopted a non-fee Distribution  Plan
for each Portfolio of the Trust.
   The  Distribution Plan recognizes that N&B  Management may use its assets and
resources, including its profits from  administration fees paid by a  Portfolio,
to  pay expenses associated with the  distribution of Portfolio shares. However,
N&B Management will  not receive  any separate fees  for such  expenses. To  the
extent  that any payments  made by a  Portfolio should be  deemed to be indirect
financing of any activity primarily intended to result in the sale of shares  of
the  Portfolio within the  context of Rule  12b-1 under the  1940 Act, then such
payments shall be deemed to be authorized by the Distribution Plan.
   Under the Distribution  Plan, the  Portfolio will require  N&B Management  to
provide  the Trust with quarterly reports  of the amounts expended in connection
with financing  any  activity  primarily  intended to  result  in  the  sale  of
Portfolio  shares,  and the  purpose for  which such  expenditure was  made. The
Distribution Plan may be terminated as to a particular Portfolio at any time  by
a  vote of a majority of the independent trustees of the Trust or by a vote of a
majority  of  the   outstanding  voting  securities   of  that  Portfolio.   The
Distribution  Plan does not require N&B  Management to perform any specific type
or level of distribution activities or  to incur any specific level of  expenses
for  activities  primarily intended  to  result in  the  sale of  shares  of the
Portfolio.
 
                                                                              19

DESCRIPTION OF INVESTMENTS
 
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Growth  Investments   may  make   the  following   investments,  among   others,
individually  or in combination, although the Series may not necessarily buy any
or all of the types of securities or use any or all of the investment techniques
that are described. These  investments may be limited  by the requirements  with
which  the  Series must  comply  if the  Portfolio  is to  qualify  as regulated
investment companies for tax purposes. The use of hedging or other techniques is
discretionary and  no  representation  is  made that  the  risk  of  AMT  Growth
Investments  will be  reduced by the  techniques discussed in  this section. For
additional information  on  the following  investments  and on  other  types  of
investments the Series may make, see the SAI.
    
 
    U.S.  GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities are
obligations of the  U.S. Treasury backed  by the  full faith and  credit of  the
United  States. U.S.  Government Agency securities  are issued  or guaranteed by
U.S. Government agencies, instrumentalities, or other U.S.  Government-sponsored
enterprises,  such  as the  Government  National Mortgage  Association ("GNMA"),
Federal National  Mortgage  Association  ("FNMA"), Federal  Home  Loan  Mortgage
Corporation  ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may be backed by the  full faith and credit of  the United States, the  issuer's
ability  to borrow from the U.S.  Treasury, subject to the Treasury's discretion
in certain cases,  or only  by the  credit of  the issuer.  U.S. Government  and
Agency  securities include certain mortgage-backed securities. The market prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID SECURITIES. The Series may  invest up to 10%  of its net assets  in
securities  that are illiquid, in that they cannot be expected to be sold within
seven days at  approximately the  price at  which they  are valued.  Due to  the
absence  of an  active trading market,  the Series may  experience difficulty in
valuing or  disposing  of illiquid  securities.  N&B Management  determines  the
liquidity  of  the  Series' securities,  under  supervision of  the  trustees of
Managers Trust. Securities which are freely tradeable in their country of origin
or in their principal market will not be considered illiquid securities even  if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally  outside the  U.S., including non-U.S.  governments, their agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated  in or indexed to foreign currencies,  which may also be affected by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective  of the  performance of  the underlying  investment. N&B Management
considers these factors in making investments for the Series.
   The Series  may each  invest up  to 10%  of the  value of  its total  assets,
measured  at the time  of investment, in  foreign securities that  are issued by
non-United States entities. The  10% limitation does not  apply with respect  to
foreign securities that are denominated in U.S. dollars, including ADRs. Foreign
securities  (including those denominated in U.S.  dollars and ADRs) are affected
by political or economic developments in foreign countries.
   Investments in foreign securities could be affected by factors generally  not
thought  to be present in the U.S. Such factors include, but are not limited to,
varying custody, brokerage and settlement practices; difficulty in pricing  some
foreign  securities; less public  information about issuers  of securities; less
governmental regulation and supervision over issuance and trading of securities;
the unavailability of  financial information or  the difficulty of  interpreting
financial   information  prepared  under   foreign  accounting  standards;  less
liquidity and more volatility in foreign securities markets; the possibility  of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or

<PAGE>
diplomatic developments; limitations on the movement of funds or other assets of
the  Series between different countries;  difficulties in invoking legal process
abroad and enforcing  contractual obligations; and  the difficulty of  assessing
economic  trends  in foreign  countries. Investment  in foreign  securities also
involves higher  brokerage  and  custodian  expenses  than  does  investment  in
domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve  other  risks  which are  not  ordinarily associated  with  investing in
domestic securities. These risks include changes in currency exchange rates  and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions  applicable  to  such   investments  or  devaluations  of   foreign
currencies.  A decline in  the exchange rate  would reduce the  value of certain
portfolio  securities  irrespective  of   the  performance  of  the   underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and  changes in rates  of exchange with  the U.S. dollar  because the underlying
security is usually denominated in foreign currency. All of the foregoing  risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN  CURRENCY TRANSACTIONS.  The Series  may enter  into forward foreign
currency exchange  contracts in  order  to protect  against adverse  changes  in
future  foreign currency exchange  rates, to facilitate  transactions in foreign
securities and to  repatriate dividend  or interest income  received in  foreign
currencies.  The Series may enter into  contracts to purchase foreign currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends to purchase. The  Series may also enter  into contracts to sell  foreign
currencies  to  protect  against a  decline  in  value of  its  foreign currency
denominated portfolio  securities due  to  a decline  in  the value  of  foreign
currencies  against the  U.S. dollar. Contracts  to sell  foreign currency could
limit any potential gain which might be realized by a Series if the value of the
hedged currency increased.
   The Series may also  enter into forward  foreign currency exchange  contracts
for  non-hedging  purposes  when  the investment  adviser  anticipates  that the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated  in that currency do not present attractive investment opportunities
and are not held in the Series.  The Series may also engage in cross-hedging  by
using  forward contracts  in one currency  to hedge against  fluctuations in the
value of  securities  denominated in  a  different currency  if  the  investment
adviser  believes  that  there  is  a pattern  of  correlation  between  the two
currencies.
   If the  Series enters  into  a forward  currency  exchange contract  to  sell
foreign  currency, it may  be required to  place cash or  high grade liquid debt
securities in  a segregated  account in  an amount  equal to  the value  of  the
Series'  total assets  committed to  the consummation  of the  forward contract.
Although these contracts  can protect  the Series from  adverse exchange  rates,
they  involve risk of loss  if N&B Management fails  to predict foreign currency
values correctly.
 
    CALL OPTIONS. The  Series may  try to reduce  the risk  of securities  price
changes  (hedge) or  generate income by  writing (selling)  covered call options
against securities held in its portfolio having a market value not exceeding 10%
of its net assets and may purchase call options in related closing transactions.
The purchaser of a call option acquires the right to buy a portfolio security at
a fixed  price during  a specified  period.  The maximum  price the  seller  may
realize  on the security during the option period is the fixed price. The seller
continues to bear the risk of a  decline in the security's price, although  this
risk is reduced by the premium received for the option.
   
   The  writing and purchasing of options is a highly specialized activity which
involves investment techniques  and risks different  from those associated  with
ordinary  portfolio  securities  transactions  including  transactional expense,
price volatility and  a high degree  of leverage. The  writing of options  could
result in significant increases in the Series' turnover rate.
    
 
                                                                              21
<PAGE>
   The  primary risks in using call options  are (1) imperfect correlation or no
correlation between changes in market value of the securities held by the Series
and the prices of the  options; (2) possible lack  of a liquid secondary  market
for options and the resulting inability to close out an option when desired; (3)
the  fact that the skills needed to  use options are different from those needed
to select the Series' securities; (4) the fact that, although use of options for
hedging purposes  can  reduce  the  risk  of loss,  they  also  can  reduce  the
opportunity  for gain, or  even result in losses,  by offsetting favorable price
movements in hedged investments; and (5) the possible inability of the Series to
purchase or sell a security at a  time that would otherwise be favorable for  it
to  do  so,  or the  possible  need  for the  Series  to  sell a  security  at a
disadvantageous time,  due to  its  need to  maintain  "cover" or  to  segregate
securities  in  connection  with  its  use  of  these  instruments.  Options are
considered derivatives.
   
    FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or  forward
commitment  transaction, the Series  commits to purchase  securities in order to
secure an advantageous price and  yield at the time  of the commitment and  pays
for  the securities when they  are delivered at a  future date (generally within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity to obtain  a favorable  price and yield.  When-issued securities  or
securities  subject to  a forward  commitment may  decline or  increase in value
during the period from  the Series' investment commitment  to the settlement  of
the purchase which may magnify fluctuation in the Series' NAV.
    
 
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements  and lend securities  from its portfolio.  In a repurchase agreement,
the Series buys a security from a  Federal Reserve member bank, or a  securities
dealer  and  simultaneously agrees  to  sell it  back at  a  higher price,  at a
specified date, usually less than a  week later. The underlying securities  must
fall within the Series' investment policies and limitations (but not limitations
as  to maturity or duration).  The Series also may  lend portfolio securities to
banks, brokerage firms, or institutional investors to earn income. Costs, delays
or losses could result  if the selling  party to a  repurchase agreement or  the
borrower  of portfolio  securities becomes  bankrupt or  otherwise defaults. N&B
Management monitors the creditworthiness of sellers and borrowers.
 
   
    REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the Series
sells securities to a bank or securities  dealer and at the same time agrees  to
repurchase  the same  securities at a  later date  at a fixed  price. During the
period before  the repurchase,  the Series  continues to  receive principal  and
interest payments on the securities. The Series is compensated by the difference
between  the current sales price  and the forward price  for the future purchase
(often referred to as the "drop"), as well as by the interest earned on the cash
proceeds of the  initial sale.  Reverse repurchase agreements  may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements.
    
 
    CONVERTIBLE SECURITIES. The Series may  invest in convertible securities.  A
convertible  security  is a  bond, debenture,  note,  preferred stock,  or other
security that may  be converted  into or exchanged  for a  prescribed amount  of
common  stock of the  same or a  different issuer within  a particular period of
time at a  specified price  or formula.  Many convertible  securities are  rated
below investment grade, or, are unrated.
 
    OTHER INVESTMENTS. The Series ordinarily invests primarily in common stocks,
when  market  conditions  warrant the  Series  may invest  in  preferred stocks,
securities convertible into or exchangeable  for common stocks, U.S.  Government
and  Agency  Securities,  investment  grade  debt  securities,  or  money market
instruments, or may retain assets in cash or cash equivalents.
 
    SHORT SELLING. The Series may attempt to limit exposure to a possible market
decline in the value of portfolio  securities through short sales of  securities
which the investment adviser believes possess volatility characteristics similar
to  those being hedged and may use short sales in an attempt to realize gain. To
effect such a transaction, the Series will
 
22
<PAGE>
borrow a security  from a  brokerage firm  to make  delivery to  the buyer.  The
Series  then is obligated to  replace the security borrowed  by purchasing it at
the market price at the time of replacement. Until the security is replaced, the
Series is required to pay to the lender any accrued interest or dividend and may
be required to pay a premium.
   The Series will realize a gain if the security declines in price between  the
date  of the short sale  and the date on which  the Series replaces the borrowed
security. The Series will incur  a loss if the  price of the security  increases
between those dates. The amount of any gain will be decreased, and the amount of
any  loss increased, by the amount of any  premium or interest the Series may be
required to pay in  connection with a  short sale. The  successful use of  short
selling  may be adversely affected by imperfect correlation between movements in
the price of  the security  sold short and  the securities  being hedged.  Short
selling may defer recognition of gains or losses into another tax period.
   
   The   Series  may  make   short  sales  against-the-box.   A  short  sale  is
"against-the-box" when, at all times during which a short position is open,  the
Series owns an equal amount of such securities, or owns securities giving it the
right,  without payment  of future consideration,  to obtain an  equal amount of
securities sold short.
    
 
    ZERO  COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay   interest
currently;  instead, they are sold  at a discount from  their face value and are
redeemed at face value when  they mature. Because zero  coupon bonds do not  pay
current income, their prices can be very volatile when interest rates change. In
calculating  its daily  income, the Series  accrues a portion  of the difference
between a zero coupon bond's purchase price and its face value.
 
    RESTRICTED SECURITIES AND  RULE 144A  SECURITIES. The Series  may invest  in
restricted  securities and Rule 144A securities. Restricted securities cannot be
sold to the public without registration under the Securities Act of 1933  ("1933
Act").  Unless  registered  for  sale,  these securities  can  be  sold  only in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted securities are generally  considered illiquid. Rule 144A  securities,
although not registered, may be resold only to qualified institutional buyers in
accordance  with Rule 144A under the  1933 Act. Unregistered securities may also
be sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B  Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.
 
                                                                              23

- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of one of the  Portfolios
are  also offered directly to qualified pension and retirement plans ("Qualified
Plans").

   EACH PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS  CORRESPONDING
SERIES  (EACH  A "SERIES")  OF ADVISERS  MANAGERS  TRUST ("MANAGERS  TRUST"), AN
OPEN-END MANAGEMENT  INVESTMENT  COMPANY.  AMT GROWTH  INVESTMENTS,  THE  GROWTH
PORTFOLIO'S  CORRESPONDING  SERIES,  IS MANAGED  BY  NEUBERGER&BERMAN MANAGEMENT

OTHER   INVESTMENT  COMPANIES  WHICH  DIRECTLY  ACQUIRE  AND  MANAGE  THEIR  OWN
PORTFOLIOS OF SECURITIES. FOR MORE INFORMATION ON THIS UNIQUE STRUCTURE THAT YOU
SHOULD   CONSIDER,    SEE   "SPECIAL    INFORMATION   REGARDING    ORGANIZATION,

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and  limitations  that  are  identical  to  those  of  the  respective
Portfolio.  The trustees  of the  Trust believe  that this  "master/feeder fund"
structure may benefit shareholders. For more information about the  organization
of   the  Portfolios  and   the  Series,  including   certain  features  of  the
master/feeder fund structure, see  "Special Information Regarding  Organization,
Capitalization, and Other Matters" on page 10. For more details about AMT Growth
Investments,  its investments and their risks,  see "Investment Program" on page
7, "Ratings of Securities" on page 8, "Borrowings" on page 8 , and  "Description
of Investments" on page 20.
    
   Here  is a  summary of  important features  of the  Growth Portfolio  and its
corresponding Series. Of course,  there can be no  assurance that the  Portfolio
will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An  investment in  any Portfolio involves  certain risks,  depending upon the
types of  investments made  by its  corresponding Series.  Special risk  factors
apply  to investments  which may  be made by  AMT Growth  Investments in foreign
securities, options and futures contracts and zero coupon bonds.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B Management,  with  the  assistance of  Neuberger&Berman  as  sub-adviser,
selects  investments for  AMT Growth  Investments. N&B  Management also provides
administrative services to AMT Growth  Investments and the Growth Portfolio  and
acts  as  distributor  of  the  shares of  the  Portfolio.  See  "Management and
Administration" in this Prospectus.
    
 
          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   
   AMT  Growth  Investments  is  managed  using  a  growth-oriented   investment
approach. This approach seeks out stocks of companies that are projected to grow
at  above-average  rates  and may  appear  poised  for a  period  of accelerated
earnings.
    
   
   The growth portfolio manager is  willing to pay a  higher share price in  the
hope  that the stock's earnings momentum will carry the stock's price higher. As
a stock's price increases based on  strong earnings, the stock's original  price
appears  low in  relation to  the growth  rate of  its earnings.  Sometimes this
happens when a particular company or  industry is temporarily out of favor  with
the  market or under-researched. This strategy is called "growth at a reasonable
price."
    
 
                                                                               3
<PAGE>
   
   In general,  AMT Growth  Investments  places a  greater emphasis  on  finding
securities whose measures of fundamental value are low in relation to the growth
rate  of their  future earnings  and cash  flow, as  projected by  the portfolio
manager, and AMT Growth Investments is therefore willing to invest in securities
with prices that are somewhat higher multiples of earnings.
    
   
   While this approach has resulted in  solid returns over the long term,  there
can  be no assurance that these results will be achieved in the future. For more
information, see "Performance Information" in this Prospectus.

1)The  per share amounts which are shown have been computed based on the average
  number of shares outstanding during each year.
    
   
2)The per share amounts and ratios which are shown reflect income and  expenses,
  including  the  Portfolio's  proportionate  share of  the  Series'  income and

3)The Portfolio transferred all of its investment securities into its Series  on
  April  28, 1995. After that date the Portfolio invested only in its Series and
  that Series, rather  than the Portfolio,  engaged in securities  transactions.
  Therefore,  after that date the Portfolio  had no portfolio turnover rate. The
  portfolio turnover rate for AMT Growth Investments for the period from May  1,
  1995 to December 31, 1995 was 35%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in  net asset value  on the performance  of the Portfolio  during each year and
 assumes dividends  and capital  gain distributions,  if any,  were  reinvested.
 Results  represent  past  performance  and  do  not  guarantee  future results.
 Investment returns and principal may fluctuate and shares when redeemed may  be
 worth  more or less than original cost. The total return information shown does
 not reflect  expenses  that  apply  to the  separate  account  or  the  related
 insurance  policies,  and inclusion  of these  charges  would reduce  the total
 return figures for all periods shown.

INVESTMENT PROGRAM
   
   The  investment  policies and  limitations of  the  Growth Portfolio  and AMT
Growth Investments  are identical.  The  Growth Portfolio  invests only  in  AMT
Growth  Investments. Therefore, the following shows  you the kinds of securities
in which AMT  Growth Investments invests.  For an explanation  of some types  of
investments, see "Description of Investments" on page 20.
    
   Investment  policies and limitations  of the Growth  Portfolio and AMT Growth
Investments are not fundamental unless otherwise specified in this Prospectus or
the SAI. While  a non-fundamental  policy or limitation  may be  changed by  the
trustees  of the  Trust or of  Managers Trust without  shareholder approval, the
Growth Portfolio  intends  to notify  shareholders  before making  any  material
change to such policies or limitations. Fundamental policies and limitations may
not  be changed without shareholder approval. There can be no assurance that AMT
Growth Investments and the Growth  Portfolio will achieve their objectives.  The
Growth  Portfolio,  by itself,  does  not represent  a  comprehensive investment
program.
   
   Additional investment techniques,  features, and  limitations concerning  AMT
Growth Investments' investment program are described in the SAI.
    
 
          AMT Growth Investments
 
- --------------------------------------------------------------------------------
 
   The  investment objective of AMT Growth  Investments and the Growth Portfolio
is to  seek  capital appreciation  without  regard to  income.  This  investment
objective  is fundamental  and may  not be changed  without the  approval of the
holders of a majority of the outstanding shares of the Portfolio and Series.
   AMT Growth Investments generally invests  in securities believed to have  the
maximum potential for long-term capital appreciation. It does not seek to invest
in securities that pay dividends or interest, and any such income is incidental.
The  Series  expects to  be almost  fully  invested in  common stocks,  often of
companies that may be temporarily out of favor in the market.
   
   The Series' aggressive growth investment  program involves greater risks  and
share   price  volatility  than  programs   that  invest  in  more  conservative
securities. Moreover, the Series does not follow a policy of active trading  for
short-term  profits.  Accordingly,  the  Series  may  be  more  appropriate  for
investors with  a longer-range  perspective.  The Series  uses  a "growth  at  a
reasonable  price"  investment  approach.  When  N&B  Management  believes  that
particular securities have greater potential for long-term capital appreciation,
the Series  may purchase  such securities  at prices  with higher  multiples  to
measures of economic value (such as earnings or cash flow) than other Series. In
addition,  the  Series  focuses  on companies  with  strong  balance  sheets and
reasonable valuations relative to  their growth rates.  It also diversifies  its
investments into many companies and industries.
    
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   While  AMT Growth Investments does not purchase securities with the intention
of profiting from short-term trading, it may sell portfolio securities prior  to
maturity when the investment adviser believes that such action is advisable.
   
   The  portfolio  turnover  rates  for  the  Growth  Portfolio  and  AMT Growth
Investments, and for  the predecessor  of the  Growth Portfolio  for the  period
prior  to  May 1,  1995,  are set  forth  under "Financial  Highlights"  in this
Prospectus. It is  anticipated that the  annual portfolio turnover  rate of  AMT
Growth Investments in some fiscal years may exceed 100%.
    
 
                                                                               7
<PAGE>
   
   Turnover  rates in excess of 100% may result in higher costs (which are borne
directly by the Series) and a possible increase in short-term capital gains  (or
losses).
    
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
    HIGH  QUALITY DEBT SECURITIES.  High quality debt  securities are securities
that have received a rating from at least one nationally recognized  statistical
rating  organization ("NRSRO"), such as Standard  & Poor's Ratings Group ("S&P")
or Moody's Investors Service, Inc. ("Moody's"), in one of the two highest rating
categories (the highest  category in the  case of commercial  paper) or, if  not
rated  by any NRSRO,  such as U.S.  Government and Agency  securities, have been
determined by N&B Management to be of comparable quality.
 
   
    INVESTMENT GRADE  DEBT SECURITIES.  "Investment grade"  debt securities  are
those  receiving one of the  four highest ratings from  Moody's, S&P, or another
NRSRO or, if unrated by any NRSRO,  deemed comparable by N&B Management to  such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's  deems securities  rated in  its fourth  highest category  (Baa) to have
speculative characteristics;  a  change in  economic  factors could  lead  to  a
weakened capacity of the issuer to repay.
    
   If  the quality of securities held  by AMT Growth Investments deteriorates so
that the  securities would  no longer  satisfy its  standards, the  Series  will
engage  in an  orderly disposition  of the  downgraded securities  to the extent
necessary to ensure that the Series' holdings of such securities will not exceed
5% of the Series' net assets.
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT Growth Investments has a fundamental policy that it may not borrow money,
except that  it may  (1) borrow  money  from banks  for temporary  or  emergency
purposes  and  not  for leveraging  or  investment  and (2)  enter  into reverse
repurchase agreements  for any  purpose,  so long  as  the aggregate  amount  of
borrowings  and reverse repurchase  agreements does not  exceed one-third of the
Series' total assets  (including the  amount borrowed)  less liabilities  (other
than   borrowings).  The  Series   does  not  expect  to   borrow  money.  As  a
non-fundamental policy,  the Series  may purchase  portfolio securities  if  its
outstanding  borrowings, including  reverse repurchase agreements,  exceed 5% of
its total assets.
   Currently, the State of California imposes borrowing limitations on  variable
insurance  product funds.  To comply with  these limitations, each  Series, as a
matter of operating policy, has undertaken that it will not borrow more than 10%
of its net  asset value  when borrowing  for any  general purpose  and will  not
borrow  more  than 25%  of its  net asset  value when  borrowing as  a temporary
measure to facilitate redemptions.  For these purposes, net  asset value is  the
market  value of all investments or assets owned less outstanding liabilities at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For temporary defensive  purposes, AMT  Growth Investments may  invest up  to
100%  of its  total assets  in cash  and cash  equivalents, U.S.  Government and
Agency Securities, commercial paper and certain other money market  instruments,
as well as repurchase agreements collateralized by the foregoing.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.

PERFORMANCE INFORMATION
   Performance  information for the Growth Portfolio  may be presented from time
to time  in advertisements  and  sales literature.  The Portfolio's  "yield"  is
calculated by dividing the Portfolio's annualized net investment income during a
recent  30-day period by the Portfolio's net asset  value on the last day of the
period. A  Portfolio's total  return  is quoted  for  the one-year  period,  the
five-year  period and ten-year  period through the  most recent calendar quarter
and is determined by  calculating the change in  value of a hypothetical  $1,000
investment in the Portfolio for each of those periods. Total return calculations
assume  reinvestment  of  all  Portfolio dividends  and  distributions  from net
investment income and net realized gains, respectively.
   All performance  information presented  for the  Portfolio is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life  Company separate accounts  investing in the Portfolio
which will take into account  insurance-related charges and expenses under  such
insurance  policies and contracts. Further information regarding the Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of one  or more  Portfolios to various  indices. Advertisements  may
also  contain  the performance  rankings  assigned certain  Portfolios  or their
advisers by various publications and statistical services. Any such  comparisons
or  rankings  are based  on past  performance  and the  statistical computations
performed by publications and services,  and are not necessarily indications  of
future  performance.  Because  the  Portfolio is  a  managed  investment vehicle
investing in a wide variety of securities, the securities owned by the Portfolio
will not match those making  up an index. Please note  that indices do not  take
into  account any  fees and expenses  of investing in  the individual securities
that they track and that individuals cannot invest in any index.
 
                                                                               9

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  one Portfolio which as of December 31, 1995 had not yet commenced investment
operations.  These  conversions  were  approved  by  the  shareholders  of   the
predecessors of the Portfolios in August 1994. Each Portfolio invests all of its
net  investable assets  in its  corresponding Series,  in each  case receiving a
beneficial interest in  that Series.  The trustees  of the  Trust may  establish
additional   portfolios  or   classes  of   shares,  without   the  approval  of
shareholders. The assets of  each Portfolio belong only  to that Portfolio,  and
the  liabilities of  each Portfolio  are borne solely  by that  Portfolio and no
other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International Portfolio which  as of  December 31,  1995 had  not yet  commenced
investment   operations)   invested   all   of   its   net   investable   assets
    
 
10
<PAGE>
   
(cash, securities, and  receivables relating to  securities) in a  corresponding
Series  of Managers Trust,  receiving a beneficial interest  in that Series. The
assets of each Series belong  only to that Series,  and the liabilities of  each
Series are borne solely by that Series and no other.
    
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor in a Series other than a Portfolio redeemed its interest in the Series,
the  Series' remaining investors  (including the Portfolio)  might, as a result,
experience higher pro rata operating expenses, thereby producing lower returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a Portfolio withdrew its investment from a Series, the trustees  would
consider  what action  might be  taken, including the  investment of  all of the
Portfolio's net investable  assets in  another pooled  investment entity  having
substantially the same investment objective as the Portfolio or the retention by
the  Portfolio of its own investment manager  to manage its assets in accordance
with its investment objective, policies,  and limitations. The inability of  the
Portfolio  to find  a suitable  replacement could  have a  significant impact on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors except as required by the 1940 Act. Each investor in a Series will  be
entitled  to  vote in  proportion  to its  relative  beneficial interest  in the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act and  other  applicable  law,  a Portfolio  will  solicit  proxies  from  its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
                                                                              11
<PAGE>
Portfolio's  shareholders. Pursuant to current  interpretations of the 1940 Act,
the Life Companies  who are shareholders  of the Portfolio  will solicit  voting
instructions from contract owners with respect to any matters that are presented
to  a vote of Portfolio shareholders. If  there are other investors in a Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN  PROVISIONS. Each investor in a  Series, including a Portfolio, will
be liable  for all  obligations of  the Series,  but not  of the  other  Series.
However, the risk of an investor in a Series incurring financial loss on account
of  such liability  would be  limited to circumstances  in which  the Series had
inadequate insurance and was unable to  meet its obligations out of its  assets.
Upon  liquidation of a Series, investors would  be entitled to share pro rata in
the net assets of the Series available for distribution to investors.

<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net asset  value  ("NAV")  per  share.  The NAVs  for  each  Portfolio  and  its
corresponding Series are calculated by subtracting liabilities from total assets
(in  the case of a  Series, the market value of  the securities the Series holds
plus cash and other assets; in the case of a Portfolio, its percentage  interest
in  its  corresponding Series,  multiplied by  the Series'  NAV, plus  any other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number of Portfolio shares  outstanding and rounding the  result to the  nearest
full cent.
   The  Growth Portfolio and  AMT Growth Investments calculate  their NAVs as of
the close of regular trading on The New York Stock Exchange ("NYSE"), usually  4
p.m. Eastern time.
   AMT  Growth  Investments  values its  equity  securities  (including options)
listed on the NYSE,  the American Stock Exchange,  other national exchanges,  or
the  NASDAQ market, and other securities for which market quotations are readily
available, at the latest sale price on the day NAV is calculated. If there is no
sale of such a security on that day, that security is valued at the mean between
its closing  bid and  asked  prices. AMT  Growth  Investments values  all  other
securities  and assets,  including restricted securities,  by a  method that the
trustees of Managers Trust believe accurately reflects fair value.
 
                                                                              13

DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   
   The  Growth Portfolio annually distributes substantially  all of its share of
AMT Growth Investments' net investment income (net of the Portfolio's expenses),
net realized  capital  gains,  and  net realized  gains  from  foreign  currency
transactions, if any, normally in February.
    
   The  Growth Portfolio  offers its shares  solely to separate  accounts of the
Life Companies. All  dividends and  other distributions are  distributed to  the
separate  accounts and will  be automatically invested  in shares. Dividends and
other distributions made by the Portfolio to the separate accounts are  taxable,
if  at  all,  to the  extent  described  in the  prospectuses  for  the Variable
Contracts.
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio  is  treated as  a  separate  entity for  Federal  income  tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986,  as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) and net  capital gain (the  excess of net  long-term capital  gain
over  net short-term capital loss) that is distributed to its shareholders. Each
Portfolio intends  to  distribute  all  of  its net  income  and  gains  to  its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service  that  each  Portfolio, as  an  investor  in a  corresponding  Series of
Managers Trust,  will be  deemed to  own a  proportionate share  of the  Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will  be treated as a  separate partnership for Federal  income tax purposes and
will not be a "publicly traded partnership," with the result that none of  those
Series  will  be subject  to  Federal income  tax  (and, instead,  each investor
therein will take into account in  determining its Federal income tax  liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The  foregoing is only a summary of  some of the important Federal income tax
considerations generally affecting  the Portfolios and  their shareholders;  see
the  SAI for a  more detailed discussion. Prospective  shareholders are urged to
consult their tax advisers.

SPECIAL CONSIDERATIONS
   
   The Portfolios serve  as the  underlying investments  for Variable  Contracts
issued  through separate accounts of the Life  Companies which may or may not be
affiliated.  See  "Distribution  and  Redemption   of  Trust  Shares"  in   this
Prospectus.
    
   
   Section  817(h) of the Code imposes  certain diversification standards on the
underlying assets of segregated asset accounts  that fund contracts such as  the
Variable Contracts (that is, the assets of the Series), which are in addition to
the  diversification requirements imposed on the  Portfolios by the 1940 Act and
Subchapter M. Failure to satisfy those  standards would result in imposition  of
Federal  income tax on a Variable Contract owner with respect to the increase in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset account that funds contracts such as the Variable Contracts is treated  as
meeting  the  diversification standards  if, as  of the  close of  each calendar
quarter, the assets in the account  meet the diversification requirements for  a
regulated  investment company and  no more than  55% of those  assets consist of
cash, cash items, U.S. Government  securities and securities of other  regulated
investment companies.
    
   The  Treasury Regulations amplify the  diversification standards set forth in
Section 817(h)  and provide  an alternative  to the  provision described  above.
Under  the  regulations,  an  investment  portfolio  will  be  deemed adequately
diversified if (i)  no more than  55% of the  value of the  total assets of  the
portfolio  is represented by any  one investment; (ii) no  more than 70% of such
value is represented  by any two  investments; (iii)  no more than  80% of  such
value is represented by any three investments; and (iv) no more than 90% of such
value  is represented by any four investments. For purposes of these Regulations
all securities of the same issuer are  treated as a single investment, but  each
United  States  government  agency  or instrumentality  shall  be  treated  as a
separate issuer.
   
   Each Series  will be  managed  with the  intention  of complying  with  these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section  817  of the  Code  and the  Treasury  Regulations thereunder  do not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder  fund structure. As described under  "Tax Status" above, the Trust
and Managers Trust  have received  a ruling  from the  Internal Revenue  Service
concluding  that the "look-through" rule of  Section 817, which would permit the
segregated asset  accounts to  look  through to  the  underlying assets  of  the
Series, will be available for the variable contract diversification test.
    
   Currently,  the State  of California imposes  diversification requirements on
variable insurance products funds investing in non-U.S. securities. Under  these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must  be invested in at least five countries; less than 80% but at least 60%, in
at least four  countries; less  than 60%  but at least  40%, in  at least  three
countries; and less than 40% but at least 20%, in at least two countries, except
that  up to  35% of  a fund's assets  may be  invested in  securities of issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United Kingdom or Germany.  The Trust and Managers  Trust intend to comply  with
the California diversification requirements, to the extent applicable.
 
                                                                              15

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B Management serves as the investment manager of AMT Growth Investments, as
administrator of the Growth Portfolio, and  as distributor of the shares of  the
Growth  Portfolio. N&B Management and its  predecessor firms have specialized in
the management of no-load  mutual funds since 1950.  In addition to serving  the
Series  of Managers Trust, N&B Management currently serves as investment manager
or investment adviser  of other  mutual funds. Neuberger&Berman,  which acts  as
sub-adviser  for the  Series and other  mutual funds managed  by N&B Management,
also serves as  investment adviser  of three other  investment companies.  These
funds had aggregate net assets of approximately $11.9 billion as of December 31,
1995.
    
   
   As  sub-adviser,  Neuberger&Berman furnishes  N&B Management  with investment
recommendations and  research  information without  added  cost to  the  Series.
Neuberger&Berman  is a member firm of the NYSE and other principal exchanges and
acts as  the Series'  principal broker  in the  purchase and  sale of  portfolio
securities  and  the  sale of  covered  call options.  Neuberger&Berman  and its
affiliates, including  N&B  Management,  manage  securities  accounts  that  had
approximately $38.7 billion of assets as of December 31, 1995. All of the voting
stock  of N&B  Management is  owned by individuals  who are  general partners of
Neuberger&Berman.
    
   
   Mark R.  Goldstein  and  Susan  Switzer are  primarily  responsible  for  the
day-to-day  management  of  AMT  Growth Investments.  Mr.  Goldstein  is  a Vice
President of N&B Management  and a general partner  of Neuberger&Berman. He  has
had  primary  responsibility  for  AMT  Growth  Investments  since  April  1993.
Previously he was  a securities analyst  and portfolio manager  with that  firm.
Susan Switzer has been an Assistant Vice President of N&B Management since March
1995,  and a portfolio manager for  Neuberger&Berman since January 1995. She has
had primary responsibility for  AMT Growth Investments  since January 1995.  Ms.
Switzer was a research analyst and assistant portfolio manager for another money
management firm from 1989 to 1994.
    
   
   N&B  Management serves as distributor in  connection with the offering of the
Growth Portfolio's  shares.  In connection  with  the sale  of  the  Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information and  to  make  only  such  statements  and  representations  as  are
contained  in the representations made in  the Portfolio's Prospectus and is not
responsible for any information given or any statements or representations  made
by  the Life Companies or by brokers or salespersons in connection with Variable
Contracts.

<PAGE>
   Neuberger&Berman acts as the principal  broker for AMT Growth Investments  in
the  purchase and sale of  portfolio securities and in  the sale of covered call
options, and for  those services  receives brokerage  commissions. In  effecting
securities  transactions, AMT Growth Investments seeks  to obtain the best price
and execution of orders. For more information, see the SAI.
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate  the possibility  that a  Series will  be adversely  affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.
 
          Expenses
 
- --------------------------------------------------------------------------------
 
   N&B   Management  provides  investment  management  services  to  AMT  Growth
Investments that include, among other things, making and implementing investment
decisions and  providing  facilities  and personnel  necessary  to  operate  the
Series.  N&B Management provides administrative services to the Growth Portfolio
that include furnishing similar facilities and personnel for the Portfolio. With
the Portfolio's consent, N&B Management is authorized to subcontract some of its
responsibilities under its administration agreement with the Portfolio to  third
parties.  For  such  administrative  and  investment  management  services,  N&B
Management is paid the following fees:

   The Growth Portfolio bears  all expenses of its  operations other than  those
borne  by N&B Management as administrator of the Portfolio and as distributor of
its shares. AMT Growth  Investments bears all expenses  of its operations  other
than  those borne by N&B  Management as investment manager  of the Series. These
expenses include, but  are not  limited to, for  the Portfolio  and the  Series,
legal  and accounting fees and compensation  for trustees who are not affiliated
with N&B Management;  for the  Portfolio, transfer agent  fees and  the cost  of
printing  and sending reports  and proxy materials to  shareholders; and for the
Series, custodial  fees for  securities.  Any expenses  which are  not  directly
attributable  to a specific Series are allocated  on the basis of the net assets
of the respective Series.
    
 
                                                                              17

          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B Management has  undertaken to  limit the Growth  Portfolio's expenses  by
reimbursing  the Portfolio for its operating expenses  and its pro rata share of
AMT Growth Investments'  operating expenses, excluding  the compensation of  N&B
Management,  taxes, interest, extraordinary  expenses, brokerage commissions and
transaction costs, that exceed  1% of the Growth  Portfolio's average daily  net
asset  value.  This undertaking  is  subject to  termination  on 60  days' prior
written notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses of the Portfolio and the Series and thereby increase total return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State Street Bank and Trust Company ("State Street"), Boston,  Massachusetts,
acts  as transfer and dividend  paying agent for the  Growth Portfolio and in so
doing performs certain bookkeeping, data processing and administrative services.
All correspondence should be sent to State Street Bank & Trust Company, P.O. Box
1978, Boston, MA  02105. State Street  provides similar services  to AMT  Growth
Investments  as  the  Series' transfer  agent.  State  Street also  acts  as the
custodian of the Series' and the Portfolio's assets.

<PAGE>
DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   
   Shares of the Trust are issued and redeemed in connection with investments in
and payments under the  Variable Contracts issued  through separate accounts  of
the  Life Companies which may or may not be affiliated with the Trust. Shares of
one Portfolio of the Trust are also offered directly to Qualified Plans.  Shares
of the Trust are purchased and redeemed at net asset value.
    
   The  Boards of Trustees  of the Trust  and Managers Trust  have undertaken to
monitor the Trust  and Managers Trust,  respectively, for the  existence of  any
material  irreconcilable conflict between the interests of the Variable Contract
owners of the Life  Companies and to  determine what action,  if any, should  be
taken  in the  event of a  conflict. The  Life Companies and  N&B Management are
responsible for reporting any potential or existing conflicts to the Boards. Due
to differences of tax  treatment and other  considerations, it is  theoretically
possible that the interests of various Variable Contract owners participating in
the  Trust and Managers Trust and the  interests of Qualified Plans investing in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or more Life  Company separate accounts  or Qualified Plans  might withdraw  its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions  will be  effected by the  separate accounts  to meet obligations
under the Variable Contracts and by the Qualified Plans. Contract owners do  not
deal  directly  with the  Trust  with respect  to  acquisition or  redemption of
shares. The trustees of the Trust may refuse to sell shares of any Portfolio  to
any  person, or suspend or terminate the  offering of shares of any Portfolio if
such action is required by law or by regulatory authorities having  jurisdiction
or  is, in the sole discretion of the trustees acting in good faith and in light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The Board of Trustees  of the Trust has  adopted a non-fee Distribution  Plan
for each Portfolio of the Trust.
   The  Distribution Plan recognizes that N&B  Management may use its assets and
resources, including its profits from  administration fees paid by a  Portfolio,
to  pay expenses associated with the  distribution of Portfolio shares. However,
N&B Management will  not receive  any separate fees  for such  expenses. To  the
extent  that any payments  made by a  Portfolio should be  deemed to be indirect
financing of any activity primarily intended to result in the sale of shares  of
the  Portfolio within the  context of Rule  12b-1 under the  1940 Act, then such
payments shall be deemed to be authorized by the Distribution Plan.
   Under the Distribution  Plan, the  Portfolio will require  N&B Management  to
provide  the Trust with quarterly reports  of the amounts expended in connection
with financing  any  activity  primarily  intended to  result  in  the  sale  of
Portfolio  shares,  and the  purpose for  which such  expenditure was  made. The
Distribution Plan may be terminated as to a particular Portfolio at any time  by
a  vote of a majority of the independent trustees of the Trust or by a vote of a
majority  of  the   outstanding  voting  securities   of  that  Portfolio.   The
Distribution  Plan does not require N&B  Management to perform any specific type
or level of distribution activities or  to incur any specific level of  expenses
for  activities  primarily intended  to  result in  the  sale of  shares  of the
Portfolio.
 
                                                                              19

DESCRIPTION OF INVESTMENTS
 
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Growth  Investments   may  make   the  following   investments,  among   others,
individually  or in combination, although the Series may not necessarily buy any
or all of the types of securities or use any or all of the investment techniques
that are described. These  investments may be limited  by the requirements  with
which  the  Series must  comply  if the  Portfolio  is to  qualify  as regulated
investment companies for tax purposes. The use of hedging or other techniques is
discretionary and  no  representation  is  made that  the  risk  of  AMT  Growth
Investments  will be  reduced by the  techniques discussed in  this section. For
additional information  on  the following  investments  and on  other  types  of
investments the Series may make, see the SAI.
    
 
    U.S.  GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities are
obligations of the  U.S. Treasury backed  by the  full faith and  credit of  the
United  States. U.S.  Government Agency securities  are issued  or guaranteed by
U.S. Government agencies, instrumentalities, or other U.S.  Government-sponsored
enterprises,  such  as the  Government  National Mortgage  Association ("GNMA"),
Federal National  Mortgage  Association  ("FNMA"), Federal  Home  Loan  Mortgage
Corporation  ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may be backed by the  full faith and credit of  the United States, the  issuer's
ability  to borrow from the U.S.  Treasury, subject to the Treasury's discretion
in certain cases,  or only  by the  credit of  the issuer.  U.S. Government  and
Agency  securities include certain mortgage-backed securities. The market prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID SECURITIES. The Series may  invest up to 10%  of its net assets  in
securities  that are illiquid, in that they cannot be expected to be sold within
seven days at  approximately the  price at  which they  are valued.  Due to  the
absence  of an  active trading market,  the Series may  experience difficulty in
valuing or  disposing  of illiquid  securities.  N&B Management  determines  the
liquidity  of  the  Series' securities,  under  supervision of  the  trustees of
Managers Trust. Securities which are freely tradeable in their country of origin
or in their principal market will not be considered illiquid securities even  if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally  outside the  U.S., including non-U.S.  governments, their agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated  in or indexed to foreign currencies,  which may also be affected by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective  of the  performance of  the underlying  investment. N&B Management
considers these factors in making investments for the Series.
   The Series  may each  invest up  to 10%  of the  value of  its total  assets,
measured  at the time  of investment, in  foreign securities that  are issued by
non-United States entities. The  10% limitation does not  apply with respect  to
foreign securities that are denominated in U.S. dollars, including ADRs. Foreign
securities  (including those denominated in U.S.  dollars and ADRs) are affected
by political or economic developments in foreign countries.
   Investments in foreign securities could be affected by factors generally  not
thought  to be present in the U.S. Such factors include, but are not limited to,
varying custody, brokerage and settlement practices; difficulty in pricing  some
foreign  securities; less public  information about issuers  of securities; less
governmental regulation and supervision over issuance and trading of securities;
the unavailability of  financial information or  the difficulty of  interpreting
financial   information  prepared  under   foreign  accounting  standards;  less
liquidity and more volatility in foreign securities markets; the possibility  of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or
 
20
<PAGE>
diplomatic developments; limitations on the movement of funds or other assets of
the  Series between different countries;  difficulties in invoking legal process
abroad and enforcing  contractual obligations; and  the difficulty of  assessing
economic  trends  in foreign  countries. Investment  in foreign  securities also
involves higher  brokerage  and  custodian  expenses  than  does  investment  in
domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve  other  risks  which are  not  ordinarily associated  with  investing in
domestic securities. These risks include changes in currency exchange rates  and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions  applicable  to  such   investments  or  devaluations  of   foreign
currencies.  A decline in  the exchange rate  would reduce the  value of certain
portfolio  securities  irrespective  of   the  performance  of  the   underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and  changes in rates  of exchange with  the U.S. dollar  because the underlying
security is usually denominated in foreign currency. All of the foregoing  risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN  CURRENCY TRANSACTIONS.  The Series  may enter  into forward foreign
currency exchange  contracts in  order  to protect  against adverse  changes  in
future  foreign currency exchange  rates, to facilitate  transactions in foreign
securities and to  repatriate dividend  or interest income  received in  foreign
currencies.  The Series may enter into  contracts to purchase foreign currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends to purchase. The  Series may also enter  into contracts to sell  foreign
currencies  to  protect  against a  decline  in  value of  its  foreign currency
denominated portfolio  securities due  to  a decline  in  the value  of  foreign
currencies  against the  U.S. dollar. Contracts  to sell  foreign currency could
limit any potential gain which might be realized by a Series if the value of the
hedged currency increased.
   The Series may also  enter into forward  foreign currency exchange  contracts
for  non-hedging  purposes  when  the investment  adviser  anticipates  that the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated  in that currency do not present attractive investment opportunities
and are not held in the Series.  The Series may also engage in cross-hedging  by
using  forward contracts  in one currency  to hedge against  fluctuations in the
value of  securities  denominated in  a  different currency  if  the  investment
adviser  believes  that  there  is  a pattern  of  correlation  between  the two
currencies.
   If the  Series enters  into  a forward  currency  exchange contract  to  sell
foreign  currency, it may  be required to  place cash or  high grade liquid debt
securities in  a segregated  account in  an amount  equal to  the value  of  the
Series'  total assets  committed to  the consummation  of the  forward contract.
Although these contracts  can protect  the Series from  adverse exchange  rates,
they  involve risk of loss  if N&B Management fails  to predict foreign currency
values correctly.
 
    CALL OPTIONS. The  Series may  try to reduce  the risk  of securities  price
changes  (hedge) or  generate income by  writing (selling)  covered call options
against securities held in its portfolio having a market value not exceeding 10%
of its net assets and may purchase call options in related closing transactions.
The purchaser of a call option acquires the right to buy a portfolio security at
a fixed  price during  a specified  period.  The maximum  price the  seller  may
realize  on the security during the option period is the fixed price. The seller
continues to bear the risk of a  decline in the security's price, although  this
risk is reduced by the premium received for the option.
   
   The  writing and purchasing of options is a highly specialized activity which
involves investment techniques  and risks different  from those associated  with
ordinary  portfolio  securities  transactions  including  transactional expense,
price volatility and  a high degree  of leverage. The  writing of options  could
result in significant increases in the Series' turnover rate.
    
 
                                                                              21
<PAGE>
   The  primary risks in using call options  are (1) imperfect correlation or no
correlation between changes in market value of the securities held by the Series
and the prices of the  options; (2) possible lack  of a liquid secondary  market
for options and the resulting inability to close out an option when desired; (3)
the  fact that the skills needed to  use options are different from those needed
to select the Series' securities; (4) the fact that, although use of options for
hedging purposes  can  reduce  the  risk  of loss,  they  also  can  reduce  the
opportunity  for gain, or  even result in losses,  by offsetting favorable price
movements in hedged investments; and (5) the possible inability of the Series to
purchase or sell a security at a  time that would otherwise be favorable for  it
to  do  so,  or the  possible  need  for the  Series  to  sell a  security  at a
disadvantageous time,  due to  its  need to  maintain  "cover" or  to  segregate
securities  in  connection  with  its  use  of  these  instruments.  Options are
considered derivatives.
   
    FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or  forward
commitment  transaction, the Series  commits to purchase  securities in order to
secure an advantageous price and  yield at the time  of the commitment and  pays
for  the securities when they  are delivered at a  future date (generally within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity to obtain  a favorable  price and yield.  When-issued securities  or
securities  subject to  a forward  commitment may  decline or  increase in value
during the period from  the Series' investment commitment  to the settlement  of
the purchase which may magnify fluctuation in the Series' NAV.
    
 
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements  and lend securities  from its portfolio.  In a repurchase agreement,
the Series buys a security from a  Federal Reserve member bank, or a  securities
dealer  and  simultaneously agrees  to  sell it  back at  a  higher price,  at a
specified date, usually less than a  week later. The underlying securities  must
fall within the Series' investment policies and limitations (but not limitations
as  to maturity or duration).  The Series also may  lend portfolio securities to
banks, brokerage firms, or institutional investors to earn income. Costs, delays
or losses could result  if the selling  party to a  repurchase agreement or  the
borrower  of portfolio  securities becomes  bankrupt or  otherwise defaults. N&B
Management monitors the creditworthiness of sellers and borrowers.
 
   
    REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the Series
sells securities to a bank or securities  dealer and at the same time agrees  to
repurchase  the same  securities at a  later date  at a fixed  price. During the
period before  the repurchase,  the Series  continues to  receive principal  and
interest payments on the securities. The Series is compensated by the difference
between  the current sales price  and the forward price  for the future purchase
(often referred to as the "drop"), as well as by the interest earned on the cash
proceeds of the  initial sale.  Reverse repurchase agreements  may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements.
    
 
    CONVERTIBLE SECURITIES. The Series may  invest in convertible securities.  A
convertible  security  is a  bond, debenture,  note,  preferred stock,  or other
security that may  be converted  into or exchanged  for a  prescribed amount  of
common  stock of the  same or a  different issuer within  a particular period of
time at a  specified price  or formula.  Many convertible  securities are  rated
below investment grade, or, are unrated.
 
    OTHER INVESTMENTS. The Series ordinarily invests primarily in common stocks,
when  market  conditions  warrant the  Series  may invest  in  preferred stocks,
securities convertible into or exchangeable  for common stocks, U.S.  Government
and  Agency  Securities,  investment  grade  debt  securities,  or  money market
instruments, or may retain assets in cash or cash equivalents.
 
    SHORT SELLING. The Series may attempt to limit exposure to a possible market
decline in the value of portfolio  securities through short sales of  securities
which the investment adviser believes possess volatility characteristics similar
to  those being hedged and may use short sales in an attempt to realize gain. To
effect such a transaction, the Series will
 
22
<PAGE>
borrow a security  from a  brokerage firm  to make  delivery to  the buyer.  The
Series  then is obligated to  replace the security borrowed  by purchasing it at
the market price at the time of replacement. Until the security is replaced, the
Series is required to pay to the lender any accrued interest or dividend and may
be required to pay a premium.
   The Series will realize a gain if the security declines in price between  the
date  of the short sale  and the date on which  the Series replaces the borrowed
security. The Series will incur  a loss if the  price of the security  increases
between those dates. The amount of any gain will be decreased, and the amount of
any  loss increased, by the amount of any  premium or interest the Series may be
required to pay in  connection with a  short sale. The  successful use of  short
selling  may be adversely affected by imperfect correlation between movements in
the price of  the security  sold short and  the securities  being hedged.  Short
selling may defer recognition of gains or losses into another tax period.
   
   The   Series  may  make   short  sales  against-the-box.   A  short  sale  is
"against-the-box" when, at all times during which a short position is open,  the
Series owns an equal amount of such securities, or owns securities giving it the
right,  without payment  of future consideration,  to obtain an  equal amount of
securities sold short.
    
 
    ZERO  COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay   interest
currently;  instead, they are sold  at a discount from  their face value and are
redeemed at face value when  they mature. Because zero  coupon bonds do not  pay
current income, their prices can be very volatile when interest rates change. In
calculating  its daily  income, the Series  accrues a portion  of the difference
between a zero coupon bond's purchase price and its face value.
 
    RESTRICTED SECURITIES AND  RULE 144A  SECURITIES. The Series  may invest  in
restricted  securities and Rule 144A securities. Restricted securities cannot be
sold to the public without registration under the Securities Act of 1933  ("1933
Act").  Unless  registered  for  sale,  these securities  can  be  sold  only in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted securities are generally  considered illiquid. Rule 144A  securities,
although not registered, may be resold only to qualified institutional buyers in
accordance  with Rule 144A under the  1933 Act. Unregistered securities may also
be sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B  Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.
 
                                                                              23

USE OF JOINT STATEMENT OF ADDITIONAL INFORMATION
   Each  Portfolio and its  corresponding Series acknowledges  that it is solely
responsible for all information or lack of information about that Portfolio  and
Series in the SAI, and no other Portfolio or Series is responsible therefor. The
trustees  of the  Trust and  of Managers  Trust have  considered this  factor in
approving each Portfolio's and Series' use of a single and combined SAI.

- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of one Portfolio are also
offered directly to qualified pension and retirement plans ("Qualified Plans").

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and limitations  that are  identical to  those of  the Portfolio.  The
trustees  of  the Trust  believe that  this  "master/feeder fund"  structure may
benefit shareholders.  For  more  information  about  the  organization  of  the
Portfolios  and the Series, including certain features of the master/feeder fund
structure, see "Special Information Regarding Organization, Capitalization,  and
Other Matters" on page 10. For more details about AMT International Investments,
its investments and their risks, see "Investment Program" on page 6, "Ratings of
Securities"  on page 7, "Borrowings" on page 8, and "Description of Investments"
on page 20.
   Here is a summary  of important features of  the International Portfolio  and
AMT  International Investments.  Of course, there  can be no  assurance that the
International Portfolio will meet its investment objective.

</TABLE>
 
          Risk Factors
 
- --------------------------------------------------------------------------------
 
   An investment in  any Portfolio  involves certain risks,  depending upon  the
types  of investments  made by  its corresponding  Series. Special  risk factors
apply to  investments which  may be  made by  AMT International  Investments  in
foreign  securities, options and  futures contracts, zero  coupon bonds and swap
agreements, and debt securities rated below investment grade. AMT  International
Investments  invests in fixed income securities, the value of which is likely to
decline in times of rising interest rates and rise in times of falling  interest
rates.  In general, the longer the maturity of a fixed income security, the more
pronounced is the  effect of  a change  in interest rates  on the  value of  the
security.
   AMT   International  Investments  seeks  long-term  capital  appreciation  by
investing primarily in a diversified  portfolio of equity securities of  issuers
organized  and doing business  principally outside the U.S.  The strategy of N&B
Management is to  select attractive investment  opportunities outside the  U.S.,
allocating   the  assets  among  economically   mature  countries  and  emerging
industrialized countries. The Series will invest primarily in equity  securities
of  medium to large  capitalization companies traded  on foreign exchanges. From
time to time,  the Series  may invest  a significant  portion of  its assets  in
Japan.  Because the Portfolio, through the  Series, invests primarily in foreign
securities, it may be subject to  greater risks and higher expenses than  equity
funds  that invest primarily  in securities of  U.S. issuers. Such  risks may be
even greater in emerging industrialized and less developed countries. The  risks
of  investing in  foreign securities include,  but are not  limited to, possible
adverse political and economic developments in a particular country, differences
between foreign and U.S. regulatory systems, and foreign securities markets that
are smaller and less well regulated than  those in the U.S. There is often  less
information publicly available about foreign
 
                                                                               3
<PAGE>
issuers,  and  many foreign  countries do  not  follow the  financial accounting
standards used in the U.S. Most of the securities held by the Series are  likely
to  be denominated in foreign currencies, and the value of these investments can
be adversely affected by fluctuations  in foreign currency values. Some  foreign
currencies  can  be volatile  and  may be  subject  to governmental  controls or
intervention. The Series may  use techniques such  as options, futures,  forward
foreign  currency exchange  contracts and short  selling, for hedging  and in an
attempt  to  realize  income.  The  use  of  hedging  or  other  techniques   is
discretionary  and no representation is made  that the risk of AMT International
Investments will be reduced by the use  of such techniques. The Series may  also
use  leverage to facilitate transactions entered  into by the Series for hedging
purposes. The use of these strategies may entail special risks. See "Borrowings"
and "Description of Investments" in this Prospectus.
 
          Management
 
- --------------------------------------------------------------------------------
 
   N&B Management,  with  the  assistance of  Neuberger&Berman  as  sub-adviser,
selects  investments  for  AMT International  Investments.  N&B  Management also
provides administrative  services  to  AMT  International  Investments  and  the
International  Portfolio and acts as distributor of the shares of the Portfolio.
See "Management and Administration" in this Prospectus.
 
          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   AMT International  Investments uses  an investment  process that  includes  a
combination  of country  selection and  individual security  selection primarily
based on a value-driven investment approach. While this approach has resulted in
solid returns over the long term, there  can be no assurance that these  results
will  be  achieved  in  the  future.  For  more  information,  see  "Performance
Information" in this Prospectus.

FINANCIAL HIGHLIGHTS
   As  of December 31, 1995, AMT International Investments and the International
Portfolio had not  yet commenced investment  operations. Accordingly,  financial
highlights are not available for the International Portfolio.
 
                                                                               5

INVESTMENT PROGRAM
   The  investment policies and  limitations of the  International Portfolio and
AMT International Investments are identical. The International Portfolio invests
only in AMT International  Investments. Therefore, the  following shows you  the
kinds  of  securities in  which AMT  International  Investments invests.  For an
explanation of some types  of investments, see  "Description of Investments"  on
page 20.
   Investment  policies and limitations  of the International  Portfolio and AMT
International Investments are not fundamental unless otherwise specified in this
Prospectus or  the SAI.  While a  non-fundamental policy  or limitation  may  be
changed  by the trustees of  the Trust or of  Managers Trust without shareholder
approval, the  International Portfolio  intends  to notify  shareholders  before
making any material change to such policies or limitations. Fundamental policies
and limitations may not be changed without shareholder approval. There can be no
assurance  that AMT  International Investments  and the  International Portfolio
will achieve their objectives.  The Portfolio, by itself,  does not represent  a
comprehensive investment program.
   Additional  investment techniques,  features, and  limitations concerning AMT
International Investments' investment programs are described in the SAI.
 
          AMT International Investments
 
- --------------------------------------------------------------------------------
 
   The  investment   objective  of   AMT  International   Investments  and   the
International  Portfolio is to seek  long-term capital appreciation by investing
primarily in a diversified  portfolio of equity  securities of foreign  issuers.
This  investment  objective  is  non-fundamental.  Foreign  issuers  are issuers
organized and doing business principally  outside the U.S. and include  non-U.S.
governments, their agencies, and instrumentalities.
   The  Series  will invest  primarily in  equity securities  of medium-to-large
capitalization companies, determined  in relation to  their respective  national
markets,  traded on foreign  exchanges. The Series normally  invests in at least
three foreign countries. The strategy of N&B Management is to select  attractive
investment  opportunities outside the U.S.,  allocating the Series' assets among
investments  in  economically  mature  countries  and  emerging   industrialized
countries. At least 65% of the Series' total assets normally will be invested in
equity  securities of  foreign issuers.  The Series  may invest  more heavily in
certain countries than in  others. From time  to time, the  Series may invest  a
significant  part of  its assets in  Japan. See "Description  of Investments" in
this Prospectus.
   The Series may  also invest  in foreign securities  in the  form of  American
Depositary   Receipts  (ADRs),  European   Depositary  Receipts  (EDRs),  Global
Depositary Receipts (GDRs),  International Depositary Receipts  (IDRs) or  other
similar  securities representing an  interest in securities  of foreign issuers,
and may purchase foreign corporate and government debt securities.
   Because the International Portfolio,  through AMT International  Investments,
invests  primarily in foreign securities, it may be subject to greater risks and
higher expenses than equity  funds that invest primarily  in securities of  U.S.
issuers.  Such risks  may be  even greater  in emerging  industrialized and less
developed countries.
   The risks of investing in foreign securities include, but are not limited to,
possible adverse political  and economic developments  in a particular  country,
differences  between foreign and U.S. regulatory systems, and foreign securities
markets that are smaller and less well-regulated than those in the U.S. There is
often less  information  publicly  available about  foreign  issuers,  and  many
foreign  countries do not follow the  financial accounting standards used in the
U.S. Most of  the securities held  by the Portfolio  are denominated in  foreign
currencies,  and the  value of  these investments  can be  adversely affected by
fluctuations in foreign currency values. Some foreign currencies can be volatile
and may be subject to governmental  controls or intervention. The Portfolio  may
use techniques such as options, futures,
 
6
<PAGE>
forward  foreign currency  exchange contracts  ("forward contracts"),  and short
selling, for hedging purposes and in an attempt to realize income. The Portfolio
may also use leverage to facilitate  transactions entered into by the  Portfolio
for hedging purposes. The use of these strategies may entail special risks.
   For  more  details  about  investments of  the  Series,  see  "Description of
Investments" in this Prospectus.
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   Although AMT International Investments does not purchase securities with  the
intention  of profiting from  short-term trading, the  Series may sell portfolio
securities prior  to maturity  when the  investment adviser  believes that  such
action is advisable.
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
    HIGH  QUALITY DEBT SECURITIES.  High quality debt  securities are securities
that have received a rating from at least one nationally recognized  statistical
rating  organization ("NRSRO"), such as Standard  & Poor's Ratings Group ("S&P")
or Moody's Investors Service, Inc. ("Moody's"), in one of the two highest rating
categories (the highest  category in the  case of commercial  paper) or, if  not
rated  by any NRSRO,  such as U.S.  Government and Agency  securities, have been
determined by N&B Management to be of comparable quality.
 
    INVESTMENT GRADE  DEBT SECURITIES.  "Investment grade"  debt securities  are
those  receiving one of the  four highest ratings from  Moody's, S&P, or another
NRSRO or, if unrated by any NRSRO,  deemed comparable by N&B Management to  such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's  deems securities  rated in  its fourth  highest category  (Baa) to have
speculative characteristics;  a  change in  economic  factors could  lead  to  a
weakened capacity of the issuer to repay.
   If  the quality  of securities  held by the  Series deteriorates  so that the
securities would no longer satisfy its  standards, the Series will engage in  an
orderly  disposition of  the downgraded  securities to  the extent  necessary to
ensure that the Series' holdings  of such securities will  not exceed 5% of  the
Series' net assets.
 
    LOWER-RATED  SECURITIES. Debt securities rated lower  than Baa by Moody's or
BBB by S&P and  debt securities determined  to be of  comparable quality by  N&B
Management   ("comparable  unrated  securities")  are  considered  to  be  below
investment grade. AMT International Investments may  invest up to 5% of its  net
assets,  measured at the time of  investment, in debt securities including those
rated below investment grade or comparable unrated securities. Securities  rated
below  investment grade ("junk bonds") are deemed by Moody's and S&P (or foreign
statistical rating organizations) to  be predominantly speculative with  respect
to  the issuer's capacity to pay interest and repay principal in accordance with
the terms of the obligations.
   Those  debt  securities  in  the  lowest  rating  categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or  developments regarding the individual issuer  are more likely to cause price
volatility and weaken  the capacity of  the issuers of  such securities to  make
principal  and  interest  payments  than  is  the  case  for  higher  grade debt
securities. An economic downturn affecting the issuer may result in an increased
incidence of  default  and a  decline  in  prices of  the  issuer's  lower-rated
securities.  In the case of lower-rated  securities structured as zero-coupon or
pay-in-kind securities, their market prices are affected to a greater extent  by
interest  rate changes, and  therefore tend to be  more volatile than securities
that pay interest periodically and in cash.
   The market for lower-rated securities may be thinner and less active than for
higher-rated securities. The  secondary market  in which  debt securities  rated
below investment grade and comparable unrated securities are traded is generally
less  liquid than the market for higher grade debt securities. Less liquidity in
the secondary trading market
 
                                                                               7
<PAGE>
could adversely affect the price at which the Series could sell a debt  security
rated  below  investment  grade, or  a  comparable unrated  security,  and could
adversely affect the daily net  asset value of the  Series' shares. At times  of
less  liquidity, it may be  more difficult to value  a debt security rated below
investment grade, or a comparable  unrated security, because such valuation  may
require  more research, and elements of judgment  may play a greater role in the
valuation  because  there  is  less  reliable,  objective  data  available.  N&B
Management  will  invest in  such  securities only  when  it concludes  that the
anticipated return to the Portfolio on  such an investment warrants exposure  to
the additional level of risk. A further description of Moody's and S&P's ratings
is included in Appendix A to the SAI.
   The  value of  the fixed  income securities in  which the  Series may invest,
measured in the currency in which they are denominated, is likely to decline  in
times  of rising interest rates.  Conversely, when rates fall,  the value of the
Series' fixed income investments  may rise. The longer  the period remaining  to
maturity,  the more  pronounced is  the effect of  interest rate  changes on the
value of a security.
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT International Investments has a fundamental policy that it may not borrow
money, except that it may (1) borrow money from banks and (2) enter into reverse
repurchase agreements  for any  purpose,  so long  as  the aggregate  amount  of
borrowings  and reverse repurchase  agreements does not  exceed one-third of the
Series' total assets  (including the  amount borrowed)  less liabilities  (other
than borrowings).
   The  Series may  borrow money from  banks to  facilitate transactions entered
into by the  Series for  hedging purposes,  which is  a form  of leverage.  This
leverage may exaggerate changes in the net asset value of the Portfolio's shares
and  the  gains and  losses on  the Series'  investments. Leverage  also creates
interest expenses;  if those  expenses exceed  the return  on transactions  that
borrowings facilitate, the Series will be in a worse position than if it had not
borrowed.  The use  of derivatives  in connection  with leverage  may create the
potential for significant  losses. The  Series may pledge  assets in  connection
with permitted borrowings.
   Currently,  the State of California imposes borrowing limitations on variable
insurance product funds.  To comply with  these limitations, each  Series, as  a
matter of operating policy, has undertaken that it will not borrow more than 10%
of  its net  asset value  when borrowing  for any  general purpose  and will not
borrow more  than 25%  of its  net asset  value when  borrowing as  a  temporary
measure  to facilitate redemptions.  For these purposes, net  asset value is the
market value of all investments or assets owned less outstanding liabilities  at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For temporary defensive purposes, AMT International Investments may invest up
to  100% of its total assets in  short-term foreign and U.S. investments such as
cash  or  cash  equivalents,  commercial  paper,  short-term  bank  obligations,
government  and agency securities and repurchase agreements. The Series may also
invest in such instruments to ensure adequate liquidity or to provide collateral
to be held in segregated accounts.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.

PERFORMANCE INFORMATION
   Performance information for the International Portfolio may be presented from
time to time in advertisements and sales literature. The Portfolio's "yield"  is
calculated by dividing the Portfolio's annualized net investment income during a
recent  30-day period by the Portfolio's net asset  value on the last day of the
period. The Portfolio's total return is quoted through the most recent  calendar
quarter  and is determined by calculating the  change in value of a hypothetical
$1,000 investment  in the  Portfolio for  each of  those periods.  Total  return
calculations  assume reinvestment  of all Portfolio  dividends and distributions
from net investment income and net realized gains, respectively.
   All performance  information presented  for the  Portfolio is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life Company separate accounts investing in the Trust which
will take  into  account  insurance-related  charges  and  expenses  under  such
insurance policies and contracts.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of the Portfolio to various indices. Advertisements may also contain
the performance  rankings  assigned the  Portfolio  or its  adviser  by  various
publications  and  statistical services.  Any such  comparisons or  rankings are
based  on  past  performance  and  the  statistical  computations  performed  by
publications  and  services,  and  are  not  necessarily  indications  of future
performance. Because the Portfolio is a managed investment vehicle investing  in
a  wide variety of  securities, the securities  owned by the  Portfolio will not
match those  making up  an index.  Please note  that indices  do not  take  into
account  any fees  and expenses of  investing in the  individual securities that
they track and that individuals cannot invest in any index.

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  the  International Portfolio  which  as of  December  31, 1995  had  not yet
commenced  investment  operations.  These  conversions  were  approved  by   the
shareholders  of  the  predecessors  of  the  Portfolios  in  August  1994. Each
Portfolio invests all of its net investable assets in its corresponding  Series,
in each case receiving a beneficial interest in that Series. The trustees of the
Trust  may establish  additional portfolios  or classes  of shares,  without the
approval of  shareholders. The  assets of  each Portfolio  belong only  to  that
Portfolio,  and  the liabilities  of  each Portfolio  are  borne solely  by that
Portfolio and no other.
 
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International Portfolio which  as of  December 31,  1995 had  not yet  commenced
investment   operations)   invested   all   of   its   net   investable   assets
 
10
<PAGE>
(cash, securities, and  receivables relating to  securities) in a  corresponding
Series  of Managers Trust,  receiving a beneficial interest  in that Series. The
assets of each Series belong  only to that Series,  and the liabilities of  each
Series are borne solely by that Series and no other.
 
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor  in the  Series other  than a  Portfolio redeemed  its interest  in the
Series, the Series' remaining  investors (including the  Portfolio) might, as  a
result,  experience higher pro rata  operating expenses, thereby producing lower
returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a  Portfolio withdrew  its investment  from the  Series, the  trustees
would  consider what action might  be taken, including the  investment of all of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the Portfolio of its own investment  manager to manage its assets in  accordance
with  its investment objective, policies, and  limitations. The inability of the
Portfolio to find  a suitable  replacement could  have a  significant impact  on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors  except as required by the 1940  Act. Each investor in the Series will
be entitled to  vote in proportion  to its relative  beneficial interest in  the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act  and  other  applicable  law,  a Portfolio  will  solicit  proxies  from its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
                                                                              11
<PAGE>
Portfolio's shareholders. Pursuant to current  interpretations of the 1940  Act,
the  Life Companies  who are shareholders  of the Portfolio  will solicit voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be  liable  for all  obligations of  the Series,  but not  of the  other Series.
However, the  risk of  an investor  in the  Series incurring  financial loss  on
account  of such liability would be limited to circumstances in which the Series
had inadequate  insurance and  was unable  to meet  its obligations  out of  its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.

<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net  asset  value  ("NAV")  per  share. The  NAVs  for  each  Portfolio  and its
corresponding Series are calculated by subtracting liabilities from total assets
(in the case of the Series, the market value of the securities the Series  holds
plus  cash and other assets; in the case of a Portfolio, its percentage interest
in its  corresponding Series,  multiplied by  the Series'  NAV, plus  any  other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number  of Portfolio shares  outstanding and rounding the  result to the nearest
full cent.
   The International Portfolio and AMT International Investments calculate their
NAVs as of the close of regular trading on The New York Stock Exchange ("NYSE"),
usually 4 p.m. Eastern time.
   Equity securities held  by AMT  International Investments are  valued at  the
last  sale price on the principal  exchange or in the principal over-the-counter
market in which such securities are traded,  as of the close of business on  the
day  the securities  are being  valued, or if  there are  no sales,  at the last
available bid price. Debt obligations held by AMT International Investments  are
valued  at the last available  bid price for such  securities, or if such prices
are not available, at prices for securities of comparable maturity, quality, and
type. Foreign  securities  are translated  from  the local  currency  into  U.S.
dollars  using current exchange rates.  AMT International Investments values all
other types  of  securities  and assets,  including  restricted  securities  and
securities  for which market  quotations are not readily  available, by a method
that the trustees of Managers Trust believe accurately reflects fair value.  AMT
International  Investments' portfolio securities are listed primarily on foreign
exchanges which may trade on days when the NYSE is closed. As a result, the  NAV
of  the  International  Portfolio may  be  significantly affected  on  days when
shareholders have no access to the Portfolio.
 
                                                                              13
<PAGE>
DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   The International  Portfolio annually  distributes substantially  all of  its
share  of  AMT  International Investments'  net  investment income  (net  of the
Portfolio's expenses), net realized capital  gains, and net realized gains  from
foreign currency transactions, if any, normally in February.
   The  International Portfolio offers its shares solely to separate accounts of
the Life Companies. All dividends and other distributions are distributed to the
separate accounts and will be automatically invested in Trust shares.  Dividends
and  other  distributions made  by the  Portfolio to  the separate  accounts are
taxable, if at all, to the extent described in the prospectuses for the Variable
Contracts.
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   Each Portfolio  is  treated as  a  separate  entity for  Federal  income  tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986,  as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) and net  capital gain (the  excess of net  long-term capital  gain
over  net short-term capital loss) that is distributed to its shareholders. Each
Portfolio intends  to  distribute  all  of  its net  income  and  gains  to  its
shareholders each year.
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service  that  each  Portfolio, as  an  investor  in a  corresponding  Series of
Managers Trust,  will be  deemed to  own a  proportionate share  of the  Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will  be treated as a  separate partnership for Federal  income tax purposes and
will not be a "publicly traded partnership," with the result that none of  those
Series  will  be subject  to  Federal income  tax  (and, instead,  each investor
therein will take into account in  determining its Federal income tax  liability
its share of the Series' income, gains, losses, deductions, and credits).
   The  foregoing is only a summary of  some of the important Federal income tax
considerations generally affecting  the Portfolios and  their shareholders;  see
the  SAI for a  more detailed discussion. Prospective  shareholders are urged to
consult their tax advisers.

<PAGE>
SPECIAL CONSIDERATIONS
   The Portfolios serve  as the  underlying investments  for Variable  Contracts
issued  through separate accounts of the Life  Companies which may or may not be
affiliated.  See  "Distribution  and  Redemption   of  Trust  Shares"  in   this
Prospectus.
   Section  817(h) of the Code imposes  certain diversification standards on the
underlying assets of segregated asset accounts  that fund contracts such as  the
Variable Contracts (that is, the assets of the Series), which are in addition to
the  diversification requirements imposed on the  Portfolios by the 1940 Act and
Subchapter M. Failure to satisfy those  standards would result in imposition  of
Federal  income tax on a Variable Contract owner with respect to the increase in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset account that funds contracts such as the Variable Contracts is treated  as
meeting  the  diversification standards  if, as  of the  close of  each calendar
quarter, the assets in the account  meet the diversification requirements for  a
regulated  investment company and  no more than  55% of those  assets consist of
cash, cash items, U.S. Government  securities and securities of other  regulated
investment companies.
   The  Treasury Regulations amplify the  diversification standards set forth in
Section 817(h)  and provide  an alternative  to the  provision described  above.
Under  the  regulations,  an  investment  portfolio  will  be  deemed adequately
diversified if (i)  no more than  55% of the  value of the  total assets of  the
portfolio  is represented by any  one investment; (ii) no  more than 70% of such
value is represented  by any two  investments; (iii)  no more than  80% of  such
value is represented by any three investments; and (iv) no more than 90% of such
value  is represented by any four investments. For purposes of these Regulations
all securities of the same issuer are  treated as a single investment, but  each
United  States  government  agency  or instrumentality  shall  be  treated  as a
separate issuer.
   Each Series  will be  managed  with the  intention  of complying  with  these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
   Section  817  of the  Code  and the  Treasury  Regulations thereunder  do not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder  fund structure. As described under  "Tax Status" above, the Trust
and Managers Trust  have received  a ruling  from the  Internal Revenue  Service
concluding  that the "look-through" rule of  Section 817, which would permit the
segregated asset  accounts to  look  through to  the  underlying assets  of  the
Series, will be available for the variable contract diversification test.
   Currently,  the State  of California imposes  diversification requirements on
variable insurance products funds investing in non-U.S. securities. Under  these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must  be invested in at least five countries; less than 80% but at least 60%, in
at least four  countries; less  than 60%  but at least  40%, in  at least  three
countries; and less than 40% but at least 20%, in at least two countries, except
that  up to  35% of  a fund's assets  may be  invested in  securities of issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United Kingdom or Germany.  The Trust and Managers  Trust intend to comply  with
the California diversification requirements, to the extent applicable.
 
                                                                              15

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   N&B  Management  serves  as  the  investment  manager  of  AMT  International
Investments, as administrator of the International Portfolio, and as distributor
of the shares of the International Portfolio. N&B Management and its predecessor
firms  have specialized in the management of no-load mutual funds since 1950. In
addition to  serving the  Series  of Managers  Trust, N&B  Management  currently
serves  as  investment  manager or  investment  adviser of  other  mutual funds.
Neuberger&Berman, which  acts as  sub-adviser for  the Series  and other  mutual
funds  managed by  N&B Management,  also serves  as investment  adviser of three
other  investment  companies.   These  funds   had  aggregate   net  assets   of
approximately $11.9 billion as of December 31, 1995.
   As  sub-adviser,  Neuberger&Berman furnishes  N&B Management  with investment
recommendations and  research  information without  added  cost to  the  Series.
Neuberger&Berman  is a  member firm of  the NYSE and  other principal exchanges.
Neuberger&Berman and its affiliates, including N&B Management, manage securities
accounts that had approximately $38.7 billion of assets as of December 31, 1995.
All of  the voting  stock of  N&B Management  is owned  by individuals  who  are
general partners of Neuberger&Berman.
   Felix   Rovelli  and  Robert  Cresci  are   the  portfolio  managers  of  AMT
International  Investments.  Mr.  Rovelli  is  primarily  responsible  for   the
day-to-day   management  of  the  portfolio   securities  of  AMT  International
Investments. Mr.  Rovelli has  been a  Vice President  at N&B  Management  since
November  1995. Mr. Rovelli has had primary responsibility for AMT International
Investments since June 1994. Previously,  he was a Senior Vice  President-Senior
Equity Portfolio Manager of BNP-N&B Global Asset Management, L.P., from May 1994
to  October 1995, and  a first Vice  President and portfolio  manager of another
mutual fund that invested in international equity securities, from April 1990 to
April 1994. Mr. Cresci is an Assistant Vice President of N&B Management and  was
an  Assistant Portfolio Manager  of BNP-N&B Global  Asset Management, L.P., from
May 1994 to October 1995. He previously served as an assistant portfolio manager
of another mutual  fund that  invested in international  equity securities  from
1992 until May 1994.
   N&B  Management serves as distributor in  connection with the offering of the
International Portfolio's shares. In connection with the sale of the Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information  and  to  make  only  such  statements  and  representations  as are
contained in the Portfolio's Prospectus. The

distributor is  responsible  only  for  information  given  and  statements  and
representations  made in the  Portfolio's Prospectus and  is not responsible for
any information given  or any  statements or  representations made  by the  Life
Companies or by brokers or salespersons in connection with Variable Contracts.
   The  partners and employees of Neuberger&Berman and officers and employees of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To mitigate the  possibility that the  Series will be  adversely affected  by
personal  trading of employees,  the Trust, Managers  Trust, N&B Management, and
Neuberger&Berman have  adopted  policies  that regulate  securities  trading  in
personal  accounts of the  portfolio managers and others  who normally come into
possession of information on portfolio  transactions. These policies comply,  in
all  material  respects,  with  the recommendations  of  the  Investment Company
Institute.

   The International Portfolio bears all  expenses of its operations other  than
those  borne  by  N&B  Management  as  administrator  of  the  Portfolio  and as
distributor of  its  shares.  AMT International  Investments  Series  bears  all
expenses  of  its  operations  other  than  those  borne  by  N&B  Management as
investment manager of the  Series. These expenses include,  but are not  limited
to, for the Portfolio and the Series, legal and accounting fees and compensation
for  trustees who  are not  affiliated with  N&B Management;  for the Portfolio,
transfer agent  fees and  the cost  of printing  and sending  reports and  proxy
materials  to shareholders; and  for the Series,  custodial fees for securities.
Any expenses  which are  not  directly attributable  to  a specific  Series  are
allocated on the basis of the net assets of the respective Series.
 
          Expense Limitation
 
- --------------------------------------------------------------------------------
 
   From  November  30,  1995  through  December  31,  1996,  N&B  Management has
undertaken to limit  the International Portfolio's  expenses by reimbursing  the
Portfolio   for  its  operating   expenses  and  its  pro   rata  share  of  AMT
 
                                                                              17
<PAGE>
International Investments'  operating expenses,  including compensation  to  N&B
Management,  but excluding taxes, interest, extraordinary expenses and brokerage
commissions, that exceed 1.70% of the Portfolio's average daily net asset  value
("Portfolio  Expense Limitation").  The Portfolio  has in  turn agreed  to repay
through December 31,  1997, expenses  borne by  N&B Management  pursuant to  the
previous  sentence, so long as the Portfolio Expense Limitation is not exceeded.
The effect of any expense  limitation by N&B Management  would be to reduce  the
Portfolio's expenses and thereby increase its total return.
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   State  Street Bank and Trust Company ("State Street"), Boston, Massachusetts,
acts as transfer and dividend paying  agent for the International Portfolio  and
in  so doing  performs certain  bookkeeping, data  processing and administrative
services. All  correspondence  should be  sent  to  State Street  Bank  &  Trust
Company, P.O. Box 1978, Boston, MA 02105. State Street provides similar services
to  AMT International  Investments as the  Series' transfer  agent. State Street
also acts as the custodian of the Series' and the Portfolios' assets.

DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and payments under the  Variable Contracts issued  through separate accounts  of
the  Life Companies which may or may not be affiliated with the Trust. Shares of
one Portfolio of the Trust are also offered directly to Qualified Plans.  Shares
of the Trust are purchased and redeemed at net asset value.
   The  Boards of Trustees  of the Trust  and Managers Trust  have undertaken to
monitor the Trust  and Managers Trust,  respectively, for the  existence of  any
material  irreconcilable conflict between the interests of the Variable Contract
owners of the Life  Companies and to  determine what action,  if any, should  be
taken  in the  event of a  conflict. The  Life Companies and  N&B Management are
responsible for reporting any potential or existing conflicts to the Boards. Due
to differences of tax  treatment and other  considerations, it is  theoretically
possible that the interests of various Variable Contract owners participating in
the  Trust and Managers Trust and the  interests of Qualified Plans investing in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or more Life  Company separate accounts  or Qualified Plans  might withdraw  its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions  will be  effected by the  separate accounts  to meet obligations
under the Variable Contracts and by the Qualified Plans. Contract owners do  not
deal  directly  with the  Trust  with respect  to  acquisition or  redemption of
shares. The trustees of the Trust may refuse to sell shares of any Portfolio  to
any  person, or suspend or terminate the  offering of shares of any Portfolio if
such action is required by law or by regulatory authorities having  jurisdiction
or  is, in the sole discretion of the trustees acting in good faith and in light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The Board of Trustees  of the Trust has  adopted a non-fee Distribution  Plan
for each Portfolio of the Trust.
   The  Distribution Plan recognizes that N&B  Management may use its assets and
resources, including its profits from  administration fees paid by a  Portfolio,
to  pay expenses associated with the  distribution of Portfolio shares. However,
N&B Management will  not receive  any separate fees  for such  expenses. To  the
extent  that any payments  made by a  Portfolio should be  deemed to be indirect
financing of any activity primarily intended to result in the sale of shares  of
the  Portfolio within the  context of Rule  12b-1 under the  1940 Act, then such
payments shall be deemed to be authorized by the Distribution Plan.
   Under the Distribution  Plan, the  Portfolio will require  N&B Management  to
provide  the Trust with quarterly reports  of the amounts expended in connection
with financing  any  activity  primarily  intended to  result  in  the  sale  of
Portfolio  shares,  and the  purpose for  which such  expenditure was  made. The
Distribution Plan may be terminated as to a particular Portfolio at any time  by
a  vote of a majority of the independent trustees of the Trust or by a vote of a
majority  of  the   outstanding  voting  securities   of  that  Portfolio.   The
Distribution  Plan does not require N&B  Management to perform any specific type
or level of distribution activities or  to incur any specific level of  expenses
for  activities  primarily intended  to  result in  the  sale of  shares  of the
Portfolio.
 
                                                                              19

DESCRIPTION OF INVESTMENTS
   In addition to the securities referred to in "Investment Program" herein, AMT
International  Investments,  as   indicated  below,  may   make  the   following
investments,  among others, individually or  in combination, although the Series
may not necessarily buy any or all of the types of securities or use any or  all
of  the  investment  techniques that  are  described. These  investments  may be
limited by the requirements with which  the Series must comply if the  Portfolio
is  to qualify as  regulated investment companies  for tax purposes.  The use of
hedging or other techniques is discretionary and no representation is made  that
the  risk of  AMT International  Investments will  be reduced  by the techniques
discussed  in  this  section.  For  additional  information  on  the   following
investments and on other types of investments the Series may make, see the SAI.
 
    U.S.  GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities are
obligations of  the U.S.Treasury  backed by  the full  faith and  credit of  the
United  States. U.S.  Government Agency securities  are issued  or guaranteed by
U.S. Government agencies, instrumentalities, or other U.S.  Government-sponsored
enterprises,  such  as the  Government  National Mortgage  Association ("GNMA"),
Federal National  Mortgage  Association  ("FNMA"), Federal  Home  Loan  Mortgage
Corporation  ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may be backed by the  full faith and credit of  the United States, the  issuer's
ability  to borrow from the U.S.  Treasury, subject to the Treasury's discretion
in certain cases,  or only  by the  credit of  the issuer.  U.S. Government  and
Agency  securities include certain mortgage-backed securities. The market prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID SECURITIES. The Series may  invest up to 10%  of its net assets  in
securities  that are illiquid, in that they cannot be expected to be sold within
seven days at  approximately the  price at  which they  are valued.  Due to  the
absence  of an  active trading market,  the Series may  experience difficulty in
valuing or  disposing  of illiquid  securities.  N&B Management  determines  the
liquidity  of  the  Series' securities,  under  supervision of  the  trustees of
Managers Trust. Securities which are freely tradeable in their country of origin
or in their principal market will not be considered illiquid securities even  if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally  outside the  U.S., including non-U.S.  governments, their agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated  in or indexed to foreign currencies,  which may also be affected by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective  of the  performance of  the underlying  investment. N&B Management
considers these factors  in making investments  for the Series.  The Series  may
enter  into forward foreign currency  contracts or futures contracts (agreements
to exchange one currency for  another at a future  date) and related options  to
manage  currency  risks and  to facilitate  transactions in  foreign securities.
Although these  contracts can  protect  the Series  from adverse  exchange  rate
changes,  they involve a risk of loss if N&B Management fails to predict foreign
currency values correctly.
   The Series  may invest  in ADRs,  EDRs, GDRs,  and IDRs.  ADRs (sponsored  or
unsponsored)  are  receipts typically  issued by  a U.S.  bank or  trust company
evidencing its ownership  of the  underlying foreign securities.  Most ADRs  are
denominated  in U.S. dollars and are traded on a U.S. stock exchange. Issuers of
the securities underlying  unsponsored ADRs are  not contractually obligated  to
disclose  material information in  the U.S. and,  therefore, there may  not be a
correlation between such  information and  the market value  of the  unsponsored
ADR. EDRs and IDRs
 
20
<PAGE>
are receipts typically issued by a European bank or trust company evidencing its
ownership  of the  underlying foreign  securities. GDRs  are receipts  issued by
either a U.S. or  non-U.S. banking institution evidencing  its ownership of  the
underlying foreign securities and are often denominated in U.S. dollars.
   Investments  in foreign securities could be affected by factors generally not
thought to be present in the U.S. Such factors include, but are not limited  to,
varying  custody, brokerage and settlement practices; difficulty in pricing some
foreign securities; less  public information about  issuers of securities;  less
governmental regulation and supervision over issuance and trading of securities;
the  unavailability of financial  information or the  difficulty of interpreting
financial  information  prepared  under   foreign  accounting  standards;   less
liquidity  and more volatility in foreign securities markets; the possibility of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or  diplomatic developments;  limitations on  the movement  of funds  or
other assets of the Series between different countries; difficulties in invoking
legal  process abroad and enforcing  contractual obligations; and the difficulty
of assessing  economic  trends  in  foreign  countries.  Investment  in  foreign
securities  also  involves higher  brokerage  and custodian  expenses  than does
investment in domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve other  risks  which are  not  ordinarily associated  with  investing  in
domestic  securities. These risks include changes in currency exchange rates and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions   applicable  to  such  investments   or  devaluations  of  foreign
currencies. A decline  in the exchange  rate would reduce  the value of  certain
portfolio   securities  irrespective  of  the   performance  of  the  underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and changes in  rates of exchange  with the U.S.  dollar because the  underlying
security  is usually denominated in foreign currency. All of the foregoing risks
may be intensified in emerging industrialized and less developed countries.
 
    JAPANESE INVESTMENTS. The  Series may  invest a substantial  portion of  its
assets  in securities of Japanese issuers.  The performance of the Portfolio may
therefore be significantly affected by events affecting the Japanese economy and
the exchange  rate between  the Japanese  yen  and the  U.S. dollar.  Japan  has
experienced  a severe recession,  including a decline in  real estate values and
other events  that  adversely affected  the  balance sheets  of  many  financial
institutions  and  indicate  that  there may  be  structural  weaknesses  in the
Japanese financial system. The effects of this economic downturn may be felt for
a considerable period and are being  exacerbated by the currency exchange  rate.
Japan  is undergoing a  period of political instability,  which may undercut its
ability to promptly  resolve trading  disputes with  the U.S.  Japan is  heavily
dependent  on foreign oil.  Japan is located  in a seismically  active area, and
severe  earthquakes   may   damage   important   elements   of   the   country's
infrastructure. Japanese economic prospects may be affected by the political and
military  situations of its near neighbors, notably North and South Korea, China
and Russia.
 
    FOREIGN CORPORATE AND GOVERNMENT DEBT  SECURITIES. The Series may invest  up
to  5%  of  its  net  assets,  measured  at  the  time  of  investment,  in U.S.
dollar-denominated and non-U.S. dollar-denominated corporate and government debt
securities of foreign issuers. The Series  may invest in debt securities of  any
rating, including those rated below investment grade and unrated securities.
 
    FOREIGN  CURRENCY TRANSACTIONS.  The Series  may enter  into forward foreign
currency exchange  contracts in  order  to protect  against adverse  changes  in
future  foreign currency exchange  rates, to facilitate  transactions in foreign
securities and to  repatriate dividend  or interest income  received in  foreign
currencies.  The Series may enter into  contracts to purchase foreign currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends to purchase. The  Series may also enter  into contracts to sell  foreign
currencies to protect against a decline in
 
                                                                              21
<PAGE>
value  of its foreign currency denominated portfolio securities due to a decline
in the value of  foreign currencies against the  U.S. dollar. Contracts to  sell
foreign  currency could limit any potential gain  which might be realized by the
Series if the value of the hedged currency increased.
   The Series may also  enter into forward  foreign currency exchange  contracts
for  non-hedging  purposes  when  the investment  adviser  anticipates  that the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated  in that currency do not present attractive investment opportunities
and are not held in the Series.  The Series may also engage in cross-hedging  by
using  forward contracts  in one currency  to hedge against  fluctuations in the
value of  securities  denominated in  a  different currency  if  the  investment
adviser  believes  that  there  is  a pattern  of  correlation  between  the two
currencies.
   If the  Series enters  into  a forward  currency  exchange contract  to  sell
foreign  currency, it may  be required to  place cash or  high grade liquid debt
securities in  a segregated  account in  an amount  equal to  the value  of  the
Series'  total assets  committed to  the consummation  of the  forward contract.
Although these contracts  can protect  the Series from  adverse exchange  rates,
they  involve risk of loss  if N&B Management fails  to predict foreign currency
values correctly.
 
    PUT AND CALL OPTIONS, FUTURES CONTRACTS, OPTIONS ON FUTURES CONTRACTS.  Each
of  these Series may try to reduce  the risk of securities price changes (hedge)
or generate income by writing (selling) covered call options against  securities
held  in its portfolio having a market value not exceeding 10% of its net assets
and may purchase call options in related closing transactions. The purchaser  of
a  call option acquires the  right to buy a portfolio  security at a fixed price
during a  specified period.  The maximum  price the  seller may  realize on  the
security  during the option period  is the fixed price.  The seller continues to
bear the  risk of  a decline  in the  security's price,  although this  risk  is
reduced by the premium received for the option.
   The  Series may enter into futures contracts and purchase and sell options on
such  contracts  on  both  the  U.S.  and  foreign  exchanges  for  hedging  and
non-hedging  purposes. AMT International Investments  may (1) enter into futures
contracts on debt securities, interest rates, securities indices, and currencies
and (2) purchase and write options on futures contracts.
   The Series may purchase and write put and call options on foreign  currencies
for  the purpose of protecting  against declines in the  dollar value of foreign
portfolio securities and against  increases in the U.S.  dollar cost of  foreign
securities to be acquired. The Series may also use options on foreign currencies
to  cross-hedge. In  addition, the  Series may purchase  call or  put options on
currencies for non-hedging purposes when the investment adviser expects that the
currency will appreciate or depreciate in value, but the securities  denominated
in  that currency do not present attractive investment opportunities and are not
held in the Series. Options on foreign currencies to be written or purchased  by
the  Series will  be traded on  U.S. and foreign  exchanges or over-the-counter.
Options on foreign currencies  which are traded  in the over-the-counter  market
may  be considered to be  illiquid securities and subject  to the restriction on
illiquid securities. (See "Illiquid Securities," above.)
   To realize  greater income  than would  be realized  on portfolio  securities
transactions  alone, the Series may write call and put options on any securities
in which it may invest or options on any securities index based on securities in
which the  Series may  invest. The  Series will  not write  a call  option on  a
security  or currency unless it owns the  underlying security or currency or has
the right to obtain it at no additional cost.
   The writing and purchasing of options is a highly specialized activity  which
involves  investment techniques and  risks different from  those associated with
ordinary portfolio  securities  transactions  including  transactional  expense,
 
22
<PAGE>
price  volatility  and a  high  degree of  leverage.  The Series  pays brokerage
commissions or spreads in connection with  its options transactions, as well  as
for  purchases and  sales of underlying  securities or currency.  The writing of
options could result in significant increases in the Series' turnover rate.
   The primary  risks in  using put  and call  options, futures  contracts,  and
options  on futures contracts, and forward foreign currency contracts or options
on foreign currencies ("Hedging Instruments")  are (1) imperfect correlation  or
no  correlation between changes  in market value  of the securities  held by the
Series and the prices of the Hedging Instruments; (2) possible lack of a  liquid
secondary  market for Hedging  Instruments and the  resulting inability to close
out a Hedging Instrument when  desired; (3) the fact  that the skills needed  to
use  Hedging Instruments are  different from those needed  to select the Series'
securities; (4) the  fact that, although  use of these  instruments for  hedging
purposes  can reduce the risk of loss,  they also can reduce the opportunity for
gain, or  even result  in losses,  by offsetting  favorable price  movements  in
hedged  investments; and (5) the possible inability of the Series to purchase or
sell a security at a time that would otherwise be favorable for it to do so,  or
the  possible need for the Series to  sell a security at a disadvantageous time,
due to its  need to maintain  "cover" or to  segregate securities in  connection
with its use of these instruments. Futures, options and forward foreign currency
contracts are considered derivatives.
 
    FORWARD  COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or forward
commitment transaction, the Series  commits to purchase  securities in order  to
secure  an advantageous price and  yield at the time  of the commitment and pays
for the securities when  they are delivered at  a future date (generally  within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity  to obtain  a favorable price  and yield.  When-issued securities or
securities subject to  a forward  commitment may  decline or  increase in  value
during  the period from  the Series' investment commitment  to the settlement of
the purchase which may magnify fluctuation in the Series' NAV.
 
    INDEXED SECURITIES. The Series may invest in indexed securities whose  value
is  linked  to  currencies,  interest  rates,  commodities,  indices,  or  other
financial indicators.  Most indexed  securities are  short-to-intermediate  term
fixed-income  securities whose values at maturity or interest rates rise or fall
according to the change in one or more specified underlying instruments. Indexed
securities may  be  positively or  negatively  indexed (i.e.,  their  value  may
increase  or decrease  if the underlying  instrument appreciates),  and may have
return  characteristics  similar  to   direct  investments  in  the   underlying
instrument  or  to one  or more  options on  the underlying  instrument. Indexed
securities may be more volatile than the underlying instrument itself.
 
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements and lend securities  from its portfolio.  In a repurchase  agreement,
the  Series buys a  security from a foreign  bank or U.S. branch  or agency of a
foreign bank, or a securities dealer  and simultaneously agrees to sell it  back
at  a higher  price, at a  specified date, usually  less than a  week later. The
underlying securities  must  fall within  the  Series' investment  policies  and
limitations  (but not limitations  as to maturity or  duration). The Series also
may lend  portfolio  securities  to banks,  brokerage  firms,  or  institutional
investors  to earn income. Costs,  delays or losses could  result if the selling
party to a repurchase agreement or the borrower of portfolio securities  becomes
bankrupt  or otherwise defaults. N&B Management monitors the creditworthiness of
sellers and borrowers.
 
    REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the Series
sells securities to a bank or securities  dealer and at the same time agrees  to
repurchase  the same  securities at a  later date  at a fixed  price. During the
period before  the repurchase,  the Series  continues to  receive principal  and
interest payments on the securities. The Series is compensated by the difference
between  the current sales price  and the forward price  for the future purchase
(often referred to as the "drop"), as well as by the interest earned on the cash
proceeds of the  initial sale.  Reverse repurchase agreements  may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements.
 
                                                                              23
<PAGE>
    CONVERTIBLE SECURITIES. The Series may  invest in convertible securities.  A
convertible  security  is a  bond, debenture,  note,  preferred stock,  or other
security that may  be converted  into or exchanged  for a  prescribed amount  of
common  stock of the  same or a  different issuer within  a particular period of
time at a  specified price  or formula.  Many convertible  securities are  rated
below investment grade, or, are unrated.
 
    OTHER  INVESTMENT COMPANIES. The  Series may invest  up to 10%  of its total
assets, measured at the  time of investment, in  the shares of other  investment
companies. Such investment may be the most practical or only manner in which the
Series  can  participate  in certain  foreign  markets because  of  the expenses
involved or  because vehicles  for investing  in certain  countries may  not  be
available  at  the  time  the  Series  is ready  to  make  an  investment.  As a
shareholder in an investment company, the  Series would bear its pro rata  share
of  that investment company's  expenses. Investment in  investment companies may
involve the payment  of substantial premiums  above the value  of such  issuers'
portfolio securities. The Series does not intend to invest in such funds unless,
in  the  judgment of  the  investment adviser,  the  potential benefits  of such
investment justify the payment of any applicable premium or sales charge.
 
    SHORT SELLING. The Series may attempt to limit exposure to a possible market
decline in the value of portfolio  securities through short sales of  securities
which the investment adviser believes possess volatility characteristics similar
to  those being hedged and may use short sales in an attempt to realize gain. To
effect such a transaction,  the Series will borrow  a security from a  brokerage
firm  to make delivery to the buyer. The Series then is obligated to replace the
security borrowed  by  purchasing  it  at  the  market  price  at  the  time  of
replacement.  Until the security is  replaced, the Series is  required to pay to
the lender  any accrued  interest  or dividend  and may  be  required to  pay  a
premium.
   The  Series will realize a gain if the security declines in price between the
date of the short sale  and the date on which  the Series replaces the  borrowed
security.  The Series will incur  a loss if the  price of the security increases
between those dates. The amount of any gain will be decreased, and the amount of
any loss increased, by the amount of  any premium or interest the Series may  be
required  to pay in  connection with a  short sale. The  successful use of short
selling may be adversely affected by imperfect correlation between movements  in
the  price of  the security  sold short and  the securities  being hedged. Short
selling may defer recognition of gains or losses into another tax period.
   The  Series  may  make   short  sales  against-the-box.   A  short  sale   is
"against-the-box"  when, at all times during which a short position is open, the
Series owns an equal amount of such securities, or own securities giving it  the
right,  without payment  of future consideration,  to obtain an  equal amount of
securities sold short.
 
    ZERO  COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay   interest
currently;  instead, they are sold  at a discount from  their face value and are
redeemed at face value when  they mature. Because zero  coupon bonds do not  pay
current income, their prices can be very volatile when interest rates change. In
calculating  its daily  income, the Series  accrues a portion  of the difference
between a zero coupon bond's purchase price and its face value.
 
    RESTRICTED SECURITIES AND  RULE 144A  SECURITIES. The Series  may invest  in
restricted  securities and Rule 144A securities. Restricted securities cannot be
sold to the public without registration under the Securities Act of 1933  ("1933
Act").  Unless  registered  for  sale,  these securities  can  be  sold  only in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted securities are generally  considered illiquid. Rule 144A  securities,
although not registered, may be resold only to qualified institutional buyers in
accordance  with Rule 144A under the  1933 Act. Unregistered securities may also
be sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B  Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.

          Limited Maturity Bond Portfolio
 
- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of one of the  Portfolios
are  also offered directly to qualified pension and retirement plans ("Qualified
Plans").
   THIS PROSPECTUS CONTAINS INFORMATION PERTAINING TO THE LIMITED MATURITY  BOND
PORTFOLIO ONLY.
 
- --------------------------------------------------------------------------------
 
   
   EACH  PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS CORRESPONDING
SERIES (EACH  A "SERIES")  OF  ADVISERS MANAGERS  TRUST ("MANAGERS  TRUST"),  AN
OPEN-END  MANAGEMENT INVESTMENT COMPANY. AMT  LIMITED MATURITY BOND INVESTMENTS,
THE LIMITED  MATURITY  BOND  PORTFOLIO'S CORRESPONDING  SERIES,  IS  MANAGED  BY
NEUBERGER&BERMAN   MANAGEMENT  INCORPORATED  ("N&B   MANAGEMENT").  AMT  LIMITED
MATURITY BOND INVESTMENTS INVESTS IN SECURITIES IN ACCORDANCE WITH AN INVESTMENT
OBJECTIVE, POLICIES, AND LIMITATIONS IDENTICAL TO THOSE OF THE LIMITED  MATURITY
BOND  PORTFOLIO.  THE  INVESTMENT  PERFORMANCE  OF  THE  LIMITED  MATURITY  BOND
PORTFOLIO WILL  DIRECTLY  CORRESPOND  WITH THE  INVESTMENT  PERFORMANCE  OF  AMT
LIMITED  MATURITY  BOND  INVESTMENTS.  THIS  "MASTER/FEEDER  FUND"  STRUCTURE IS
DIFFERENT FROM THAT OF  MANY OTHER INVESTMENT  COMPANIES WHICH DIRECTLY  ACQUIRE
AND  MANAGE THEIR  OWN PORTFOLIOS  OF SECURITIES.  FOR MORE  INFORMATION ON THIS
UNIQUE STRUCTURE THAT  YOU SHOULD CONSIDER,  SEE "SPECIAL INFORMATION  REGARDING
ORGANIZATION, CAPITALIZATION, AND OTHER MATTERS" ON PAGE 11.

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and  limitations  that  are  identical  to  those  of  the  respective
Portfolio.  The trustees  of the  Trust believe  that this  "master/feeder fund"
structure may benefit shareholders. For more information about the  organization
of   the  Portfolios  and   the  Series,  including   certain  features  of  the
master/feeder fund structure, see  "Special Information Regarding  Organization,
Capitalization,  and  Other Matters"  on  page 11.  For  more details  about AMT
Limited  Maturity  Bond  Investments,  its  investments  and  their  risks,  see
"Investment  Program" on page 6, "Ratings of Securities" on page 7, "Borrowings"
on page 8, and "Description of Investments" on page 21.
    
   Here is  a  summary  of  important features  of  the  Limited  Maturity  Bond
Portfolio  and its  corresponding Series. Of  course, there can  be no assurance
that the Portfolio will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An investment in  any Portfolio  involves certain risks,  depending upon  the
types  of investments  made by  its corresponding  Series. Special  risk factors
apply to investments which may be made by AMT Limited Maturity Bond  Investments
in  foreign securities,  options and futures  contracts, zero  coupon bonds, and
debt  securities  rated  below  investment  grade.  AMT  Limited  Maturity  Bond
Investments  invests in fixed income securities, the value of which is likely to
decline in times of rising interest rates and rise in times of falling  interest
rates.  In general, the longer the maturity of a fixed income security, the more
pronounced is the  effect of  a change  in interest rates  on the  value of  the
security.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management,  with  the assistance  of  Neuberger&Berman  as sub-adviser,
selects investments for  AMT Limited Maturity  Bond Investments. N&B  Management
also  provides administrative services to  AMT Limited Maturity Bond Investments
and the Limited Maturity Bond Portfolio and acts as distributor of the shares of
the Portfolio. See "Management and Administration" in this Prospectus.

  NOTES:
   
1)The  per share amounts which are shown have been computed based on the average
  number of shares outstanding during each year.
    
   
2)The per share amounts and ratios which are shown reflect income and  expenses,
  including  the  Portfolio's  proportionate  share of  the  Series'  income and
  expenses.
    
   
3)On May  2,  1988,  the  predecessor  of  the  Portfolio  changed  its  primary
  investment  objective to obtain the highest current income consistent with low
  risk to principal and liquidity  through investments in limited maturity  debt
  securities.
    
   
4)The  amounts  shown at  this caption  for a  share outstanding  throughout the
  period may  not  accord with  the  change in  aggregate  gains and  losses  in
  securities  for the period because  of the timing of  sales and repurchases of
  Portfolio shares in relation to fluctuating market values for the Portfolio.
    
   
5)The Portfolio transferred all of its investment securities into its Series  on
  April  28, 1995. After that date the Portfolio invested only in its Series and
  that Series, rather  than the Portfolio,  engaged in securities  transactions.
  Therefore,  after that date the Portfolio  had no portfolio turnover rate. The
  portfolio turnover  rate for  AMT Limited  Maturity Bond  Investments for  the
  period from May 1, 1995 to December 31, 1995 was 78%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in  net asset value  on the performance  of the Portfolio  during each year and
 assumes dividends  and capital  gain distributions,  if any,  were  reinvested.
 Results  represent  past  performance  and  do  not  guarantee  future results.
 Investment returns and principal may fluctuate and shares when redeemed may  be
 worth  more or less than original cost. The total return information shown does
 not reflect  expenses  that  apply  to the  separate  account  or  the  related
 insurance  policies,  and inclusion  of these  charges  would reduce  the total
 return figures for all years shown.

INVESTMENT PROGRAM
    
   
   The  investment  policies  and  limitations  of  the  Limited  Maturity  Bond
Portfolio and AMT Limited Maturity  Bond Investments are identical. The  Limited
Maturity  Bond Portfolio invests only in  AMT Limited Maturity Bond Investments.
Therefore, the following shows you the kinds of securities in which AMT  Limited
Maturity  Bond  Investments  invests.  For  an  explanation  of  some  types  of
investments, see "Description of Investments" on page 21.
    
   
   Investment policies and  limitations of the  Limited Maturity Bond  Portfolio
and  AMT Limited Maturity Bond Investments  are not fundamental unless otherwise
specified in  this Prospectus  or the  SAI. While  a non-fundamental  policy  or
limitation  may be  changed by the  trustees of  the Trust or  of Managers Trust
without shareholder approval,  the Limited  Maturity Bond  Portfolio intends  to
notify  shareholders  before  making any  material  change to  such  policies or
limitations. Fundamental policies  and limitations  may not  be changed  without
shareholder  approval. There can be no  assurance that AMT Limited Maturity Bond
Investments  and  the  Limited  Maturity  Bond  Portfolio  will  achieve   their
objectives. The Limited Maturity Bond Portfolio, by itself, does not represent a
comprehensive investment program.
    
   
   Additional  investment techniques,  features, and  limitations concerning AMT
Limited Maturity Bond Investments' investment program are described in the SAI.
    
 
          AMT Limited Maturity Bond Investments
 
- --------------------------------------------------------------------------------
 
   The investment objective  of AMT  Limited Maturity Bond  Investments and  the
Limited  Maturity  Bond  Portfolio  is to  provide  the  highest  current income
consistent with  low risk  to principal  and liquidity;  and secondarily,  total
return.  This investment objective is fundamental and may not be changed without
the approval of  the holders  of a  majority of  the outstanding  shares of  the
Portfolio and Series.
   AMT  Limited Maturity Bond Investments invests  in a diversified portfolio of
fixed and  variable  rate debt  securities  and  seeks to  increase  income  and
preserve or enhance total return by actively managing average portfolio duration
in light of market conditions and trends.
   
   AMT  Limited Maturity Bond Investments invests  in a diversified portfolio of
short-to-intermediate-term  U.S.  Government  and  Agency  securities  and  debt
securities issued by financial institutions, corporations, and others, primarily
investment  grade.  These  securities include  mortgage-backed  and asset-backed
securities, repurchase agreements  with respect  to U.S.  Government and  Agency
securities,  and foreign investments. AMT  Limited Maturity Bond Investments may
invest up to 10% of its net assets, measured at the time of investment, in  debt
securities  rated below investment grade, or in unrated securities determined to
be of comparable  quality by N&B  Management ("comparable unrated  securities").
Debt  securities rated below Baa by Moody's Investors Services, Inc. ("Moody's")
and below BBB by Standard  & Poor's Ratings Group  ("S&P") are considered to  be
below  investment  grade. Securities  rated below  investment  grade as  well as
comparable unrated securities are often considered to be speculative and usually
entail greater risk. AMT Limited Maturity  Bond Investments will invest in  debt
securities  rated  no lower  than  B by  Moody's  or S&P  or  comparable unrated
securities. AMT Limited Maturity Bond Investments may invest up to 5% of its net
assets, measured at  the time of  investment, in municipal  securities when  N&B
Management  believes such securities may  outperform other available issues. The
Series may purchase and sell covered call and put options, interest-rate futures
contracts, and options  on those  futures contracts  and may  engage in  lending
portfolio securities. The Series' dollar-weighted average portfolio duration may
range  up to  four years.  For more information  on lower  rated securities, see
"Ratings of Securities"  in this  Prospectus, "Fixed Income  Securities" in  the
SAI, and Appendix A of the SAI.

          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   While  AMT the Limited Maturity Bond Investments does not purchase securities
with the intention of profiting from  short-term trading, it may sell  portfolio
securities  prior to  maturity when  the investment  adviser believes  that such
action is advisable.
   
   The portfolio turnover rates for the Limited Maturity Bond Portfolio and  AMT
Limited  Maturity Bond Investments, and for the predecessor of the Portfolio for
the period prior to May 1, 1995,  are set forth under "Financial Highlights"  in
this Prospectus.
    
   
   It  is anticipated  that the  annual portfolio  turnover rate  of AMT Limited
Maturity Bond Investments in some fiscal  years may exceed 100%. Turnover  rates
in  excess of 100% may  result in higher costs (which  are borne directly by the
Series) and a possible increase in short-term capital gains (or losses).
    
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
   
    HIGH QUALITY DEBT  SECURITIES. High quality  debt securities are  securities
that  have received a rating from at least one nationally recognized statistical
rating organization ("NRSRO"), such as S&P or Moody's, in one of the two highest
rating categories (the highest category in the case of commercial paper) or,  if
not rated by any NRSRO, such as U.S. Government and Agency securities, have been
determined by N&B Management to be of comparable quality.
    
 
   
    INVESTMENT  GRADE DEBT  SECURITIES. "Investment  grade" debt  securities are
those receiving one of  the four highest ratings  from Moody's, S&P, or  another
NRSRO  or, if unrated by any NRSRO,  deemed comparable by N&B Management to such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's deems securities  rated in  its fourth  highest category  (Baa) to  have
speculative  characteristics;  a  change in  economic  factors could  lead  to a
weakened capacity of the issuer to repay.
    
   If the quality  of securities  held by the  Series deteriorates  so that  the
securities  would no longer satisfy its standards,  the Series will engage in an
orderly disposition  of the  downgraded securities  to the  extent necessary  to
ensure  that the Series' holdings  of such securities will  not exceed 5% of the
Series' net assets.
   
    LOWER-RATED SECURITIES. Debt securities rated  lower than Baa by Moody's  or
BBB  by S&P and  debt securities determined  to be of  comparable quality by N&B
Management  ("comparable  unrated  securities")  are  considered  to  be   below
investment  grade. AMT Limited Maturity Bond Investments may invest up to 10% of
its net assets,  measured at the  time of investment,  in debt securities  rated
below  investment  grade,  but rated  no  lower than  B  by Moody's  or  S&P, or
comparable unrated securities.  Securities rated below  investment grade  ("junk
bonds")   are  deemed  by  Moody's  and   S&P  (or  foreign  statistical  rating
organizations) to  be predominantly  speculative with  respect to  the  issuer's
capacity to pay interest and repay principal in accordance with the terms of the
obligations.
    
   
   Those  debt  securities  in  the  lowest  rating  categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or developments regarding the individual issuer  are more likely to cause  price
volatility  and weaken the  capacity of the  issuers of such  securities to make
principal and  interest  payments  than  is  the  case  for  higher  grade  debt
securities. An economic downturn affecting the issuer may result in an increased
incidence  of  default  and a  decline  in  prices of  the  issuer's lower-rated
securities. In the case of  lower-rated securities structured as zero-coupon  or
pay-in-kind  securities, their market prices are affected to a greater extent by
interest rate changes, and  therefore tend to be  more volatile than  securities
that pay interest periodically and in cash.
    
   
   The market for lower-rated securities may be thinner and less active than for
higher-rated  securities. The  secondary market  in which  debt securities rated
below  investment   grade  and   comparable   unrated  securities   are   traded
    
 
                                                                               7
<PAGE>
   
is  generally less liquid than the market for higher grade debt securities. Less
liquidity in the secondary  trading market could adversely  affect the price  at
which  the Series could sell a debt  security rated below investment grade, or a
comparable unrated  security, and  could adversely  affect the  daily net  asset
value  of  the  Series' shares.  At  times of  less  liquidity, it  may  be more
difficult to value a debt security rated below investment grade, or a comparable
unrated security, because such valuation may require more research, and elements
of judgment may  play a  greater role  in the  valuation because  there is  less
reliable,   objective  data  available.  N&B  Management  will  invest  in  such
securities only when  it concludes that  the anticipated return  to the  Limited
Maturity  Bond  Portfolio  on  such  an  investment  warrants  exposure  to  the
additional level of risk. A further description of Moody's and S&P's ratings  is
included in Appendix A to the SAI.
    
   
   The  value of  the fixed  income securities in  which the  Series may invest,
measured in the currency in which they are denominated, is likely to decline  in
times  of rising interest rates.  Conversely, when rates fall,  the value of the
Series' fixed income investments  may rise. The longer  the period remaining  to
maturity,  the more  pronounced is  the effect of  interest rate  changes on the
value of a security.
    
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT Limited Maturity Bond  Investments has a fundamental  policy that it  may
not  borrow money, except that it may  (1) borrow money from banks for temporary
or emergency purposes and  not for leveraging or  investment and (2) enter  into
reverse  repurchase agreements for any purpose,  so long as the aggregate amount
of borrowings and reverse repurchase agreements does not exceed one-third of the
Series' total assets  (including the  amount borrowed)  less liabilities  (other
than   borrowings).  The  Series   does  not  expect  to   borrow  money.  As  a
non-fundamental policy,  the Series  may purchase  portfolio securities  if  its
outstanding  borrowings, including  reverse repurchase agreements,  exceed 5% of
its total assets. Dollar rolls are treated as reverse repurchase agreements.
   Currently, the State of California imposes borrowing limitations on  variable
insurance  product funds.  To comply  with these  limitations, the  Series, as a
matter of operating policy, has undertaken that it will not borrow more than 10%
of its net  asset value  when borrowing  for any  general purpose  and will  not
borrow  more  than 25%  of its  net asset  value when  borrowing as  a temporary
measure to facilitate redemptions.  For these purposes, net  asset value is  the
market  value of all investments or assets owned less outstanding liabilities at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For temporary defensive purposes, AMT  Limited Maturity Bond Investments  may
invest  up  to 100%  of  its total  assets in  cash  and cash  equivalents, U.S.
Government and  Agency  Securities, commercial  paper  and certain  other  money
market  instruments,  as well  as  repurchase agreements  collateralized  by the
foregoing. Also, for  temporary defensive  purposes, AMT  Limited Maturity  Bond
Investments may adopt shorter weighted average duration than normal.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.

<PAGE>
   
          Duration
    
 
- --------------------------------------------------------------------------------
 
   
   Duration  is a measure  of the sensitivity  of debt securities  to changes in
market interest  rates,  based on  the  entire  cash flow  associated  with  the
securities,   including  payments  occurring  before   the  final  repayment  of
principal. N&B Management  utilizes duration  as a tool  in portfolio  selection
instead of the more traditional measure known as "term to maturity" in portfolio
selection for AMT Limited Maturity Bond Investments. "Term to maturity" measures
only  the  time until  a debt  security  provides its  final payment,  taking no
account of the pattern  of the security's payments  prior to maturity.  Duration
incorporates  a bond's yield, coupon interest  payments, final maturity and call
features  into  one  measure.  Duration  therefore  provides  a  more   accurate
measurement  of a bond's  likely price change  in response to  a given change in
market interest rates.  The longer the  duration, the greater  the bond's  price
movement  will be as interest  rates change. For any  fixed income security with
interest payments  occurring prior  to  the payment  of principal,  duration  is
always less than maturity.
    
   
   Futures,  options, and options on futures  have durations which are generally
related to the duration of the securities underlying them. Holding long  futures
or call option positions will lengthen the Series' duration by approximately the
same  amount as would holding an equivalent amount of the underlying securities.
Short futures  or put  options  have durations  roughly  equal to  the  negative
duration of the securities that underlie these positions, and have the effect of
reducing portfolio duration by approximately the same amount as would selling an
equivalent amount of the underlying securities.
    
   
   There  are some situations where even  the standard duration calculation does
not properly reflect  the interest  rate exposure  of a  security. For  example,
floating and variable rate securities often have final maturities of ten or more
years; however, their interest rate exposure corresponds to the frequency of the
coupon  reset. Another example where the  interest rate exposure is not properly
captured by duration is the case of mortgage-backed securities. The stated final
maturity of such securities is generally 30 years, but current prepayment  rates
are critical in determining the securities' interest rate exposure. In these and
other  similar  situations,  N&B  Management,  where  permitted,  will  use more
sophisticated analytical  techniques that  incorporate the  economic life  of  a
security into the determination of its interest rate exposure.

PERFORMANCE INFORMATION
   
   Performance  information  for  the  Limited Maturity  Bond  Portfolio  may be
presented from  time  to  time  in  advertisements  and  sales  literature.  The
Portfolio's  "yield" is  calculated by  dividing the  Portfolio's annualized net
investment income during  a recent 30-day  period by the  Portfolio's net  asset
value  on the last day of the period. The Portfolio's total return is quoted for
the one-year period, the five-year period  and ten-year period through the  most
recent  calendar quarter and is determined by calculating the change in value of
a hypothetical $1,000  investment in the  Portfolio for each  of those  periods.
Total  return calculations  assume reinvestment  of all  Portfolio dividends and
distributions from net investment income and net realized gains, respectively.
    
   All performance  information presented  for the  Portfolio is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life Company separate accounts investing in the Trust which
will take  into  account  insurance-related  charges  and  expenses  under  such
insurance  policies and contracts. Further information regarding the Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of the Portfolio to various indices. Advertisements may also contain
the performance  rankings  assigned the  Portfolio  or its  adviser  by  various
publications  and  statistical services.  Any such  comparisons or  rankings are
based  on  past  performance  and  the  statistical  computations  performed  by
publications  and  services,  and  are  not  necessarily  indications  of future
performance. Because the Portfolio is a managed investment vehicle investing  in
a  wide variety of  securities, the securities  owned by the  Portfolio will not
match those  making up  an index.  Please note  that indices  do not  take  into
account  any fees  and expenses of  investing in the  individual securities that
they track and that individuals cannot invest in any index.

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  the  one Portfolio  which  as of  December 31,  1995  had not  yet commenced
investment operations. These  conversions were approved  by the shareholders  of
the predecessors of the Portfolios in August 1994. Each Portfolio invests all of
its  net investable assets in its corresponding Series, in each case receiving a
beneficial interest in  that Series.  The trustees  of the  Trust may  establish
additional   portfolios  or   classes  of   shares,  without   the  approval  of
shareholders. The assets of  each Portfolio belong only  to that Portfolio,  and
the  liabilities of  each Portfolio  are borne solely  by that  Portfolio and no
other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International Portfolio which  as of  December 31,  1995 had  not yet  commenced
investment   operations)   invested   all   of   its   net   investable   assets
    
 
                                                                              11
<PAGE>
   
(cash, securities, and  receivables relating to  securities) in a  corresponding
Series  of Managers Trust,  receiving a beneficial interest  in that Series. The
assets of each Series belong  only to that Series,  and the liabilities of  each
Series are borne solely by that Series and no other.
    
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor  in the  Series other  than a  Portfolio redeemed  its interest  in the
Series, the Series' remaining  investors (including the  Portfolio) might, as  a
result,  experience higher pro rata  operating expenses, thereby producing lower
returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a  Portfolio withdrew  its investment  from the  Series, the  trustees
would  consider what action might  be taken, including the  investment of all of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the Portfolio of its own investment  manager to manage its assets in  accordance
with  its investment objective, policies, and  limitations. The inability of the
Portfolio to find  a suitable  replacement could  have a  significant impact  on
shareholders.
 
    INVESTOR  MEETINGS AND VOTING. The Series normally will not hold meetings of
investors except as required by the 1940  Act. Each investor in the Series  will
be  entitled to vote  in proportion to  its relative beneficial  interest in the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act and  other  applicable  law,  a Portfolio  will  solicit  proxies  from  its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
12
<PAGE>
Portfolio's  shareholders. Pursuant to current  interpretations of the 1940 Act,
the Life Companies  who are shareholders  of the Portfolio  will solicit  voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there  can be no assurance that any issue  that receives a majority of the votes
cast by Portfolio  shareholders will  receive a majority  of votes  cast by  all
Series  investors; indeed,  if other investors  hold a majority  interest in the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be liable  for all  obligations of  the Series,  but not  of the  other  Series.
However,  the risk  of an  investor in  the Series  incurring financial  loss on
account of such liability would be limited to circumstances in which the  Series
had  inadequate insurance  and was  unable to  meet its  obligations out  of its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.
 
                                                                              13
<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net asset  value  ("NAV")  per  share.  The NAVs  for  each  Portfolio  and  its
corresponding Series are calculated by subtracting liabilities from total assets
(in  the case of the Series, the market value of the securities the Series holds
plus cash and other assets; in the case of a Portfolio, its percentage  interest
in  its  corresponding Series,  multiplied by  the Series'  NAV, plus  any other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number of Portfolio shares  outstanding and rounding the  result to the  nearest
full cent.
   The Limited Maturity Bond Portfolio and AMT Limited Maturity Bond Investments
calculate  their NAVs as of  the close of regular trading  on The New York Stock
Exchange ("NYSE"), usually 4 p.m. Eastern time.
   
   AMT Limited Maturity Bond Investments generally values its securities on  the
basis  of bid quotations  from independent pricing  services or principal market
makers, or, if quotations are  not available, by a  method that the trustees  of
Managers Trust believe accurately reflects fair value. AMT Limited Maturity Bond
Investments  periodically verifies valuations provided  by the pricing services.
Short-term securities with remaining maturities of less than 60 days are  valued
at cost which, when combined with interest earned, approximates market value.

DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   
   The Limited Maturity Bond Portfolio annually distributes substantially all of
its  share of AMT Limited Maturity  Bond Investments' net investment income (net
of the Portfolio's expenses), net realized capital gains, and net realized gains
from foreign currency transactions, if any, normally in February.
    
   
   The Limited  Maturity Bond  Portfolio offers  its shares  solely to  separate
accounts  of  the  Life Companies.  All  dividends and  other  distributions are
distributed to the separate accounts and will be automatically invested in Trust
shares. Dividends and other distributions made by the Portfolio to the  separate
accounts are taxable, if at all, to the extent described in the prospectuses for
the Variable Contracts.
    
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each  Portfolio  is  treated as  a  separate  entity for  Federal  income tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment  company" under Subchapter M of the Internal Revenue Code of 1986, as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income, net short-term capital gain and net gains from certain foreign  currency
transactions)  and net  capital gain (the  excess of net  long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.  Each
Portfolio  intends  to  distribute  all  of its  net  income  and  gains  to its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service that  each  Portfolio, as  an  investor  in a  corresponding  Series  of
Managers  Trust, will  be deemed  to own  a proportionate  share of  the Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will be treated as  a separate partnership for  Federal income tax purposes  and
will  not be a "publicly traded partnership," with the result that none of those
Series will  be subject  to  Federal income  tax  (and, instead,  each  investor
therein  will take into account in  determining its Federal income tax liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The foregoing is only a summary of  some of the important Federal income  tax
considerations  generally affecting  the Portfolios and  their shareholders; see
the SAI for a  more detailed discussion. Prospective  shareholders are urged  to
consult their tax advisers.
 
                                                                              15

SPECIAL CONSIDERATIONS
   The  Portfolios serve  as the  underlying investments  for Variable Contracts
issued through separate accounts of the Life  Companies which may or may not  be
affiliated.   See  "Distribution  and  Redemption   of  Trust  Shares"  in  this
Prospectus.
   
   Section 817(h) of the Code  imposes certain diversification standards on  the
underlying  assets of segregated asset accounts  that fund contracts such as the
Variable Contracts (that is, the assets of the Series), which are in addition to
the diversification requirements imposed on the  Portfolios by the 1940 Act  and
Subchapter  M. Failure to satisfy those  standards would result in imposition of
Federal income tax on a Variable Contract owner with respect to the increase  in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset  account that funds contracts such as the Variable Contracts is treated as
meeting the  diversification standards  if, as  of the  close of  each  calendar
quarter,  the assets in the account  meet the diversification requirements for a
regulated investment company  and no more  than 55% of  those assets consist  of
cash,  cash items, U.S. Government securities  and securities of other regulated
investment companies.
    
   The Treasury Regulations amplify the  diversification standards set forth  in
Section  817(h) and  provide an  alternative to  the provision  described above.
Under the  regulations,  an  investment  portfolio  will  be  deemed  adequately
diversified  if (i) no  more than 55%  of the value  of the total  assets of the
portfolio is represented by any  one investment; (ii) no  more than 70% of  such
value  is represented  by any two  investments; (iii)  no more than  80% of such
value is represented by any three investments; and (iv) no more than 90% of such
value is represented by any four investments. For purposes of these  Regulations
all  securities of the same issuer are  treated as a single investment, but each
United States  government  agency  or  instrumentality shall  be  treated  as  a
separate issuer.
   
   The  Series  will  be managed  with  the  intention of  complying  with these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section 817  of the  Code  and the  Treasury  Regulations thereunder  do  not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder fund structure. As described  under "Tax Status" above, the  Trust
and  Managers Trust  have received  a ruling  from the  Internal Revenue Service
concluding that the "look-through" rule of  Section 817, which would permit  the
segregated  asset  accounts to  look  through to  the  underlying assets  of the
Series, will be available for the variable contract diversification test.
    
   Currently, the State  of California imposes  diversification requirements  on
variable  insurance products funds investing in non-U.S. securities. Under these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must be invested in at least five countries; less than 80% but at least 60%,  in
at  least four  countries; less  than 60% but  at least  40%, in  at least three
countries; and less than 40% but at least 20%, in at least two countries, except
that up to  35% of  a fund's  assets may be  invested in  securities of  issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United  Kingdom or Germany. The  Trust and Managers Trust  intend to comply with
the California diversification requirements, to the extent applicable.

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The trustees  of  the Trust  and  the trustees  of  Managers Trust,  who  are
currently  the same individuals, have  overall responsibility for the operations
of each  Portfolio  and each  Series,  respectively. The  SAI  contains  general
background  information  about each  trustee  and officer  of  the Trust  and of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or directors of  N&B Management  and/or partners  of Neuberger&Berman  serve
without  compensation from  the Portfolios  or the  Series. The  trustees of the
Trust and of Managers Trust, including a majority of those trustees who are  not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written  procedures reasonably appropriate  to deal with  potential conflicts of
interest, including,  if necessary,  creating a  separate board  of trustees  of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management serves as the investment manager of AMT Limited Maturity Bond
Investments, as administrator  of the  Limited Maturity Bond  Portfolio, and  as
distributor of the shares of the Limited Maturity Bond Portfolio. N&B Management
and  its predecessor firms have specialized  in the management of no-load mutual
funds since  1950. In  addition to  serving the  Series of  Managers Trust,  N&B
Management currently serves as investment manager or investment adviser of other
mutual  funds. Neuberger&Berman,  which acts as  sub-adviser for  the Series and
other mutual funds managed by N&B Management, also serves as investment  adviser
of  three other  investment companies. These  funds had aggregate  net assets of
approximately $11.9 billion as of December 31, 1995.
    
   
   As sub-adviser,  Neuberger&Berman furnishes  N&B Management  with  investment
recommendations  and  research information  without  added cost  to  the Series.
Neuberger&Berman is a member firm of the NYSE and other principal exchanges  and
acts  as the  Series' principal  broker to the  extent a  broker is  used in the
purchase and sale of portfolio securities and the sale of covered call  options.
Neuberger&Berman and its affiliates, including N&B Management, manage securities
accounts that had approximately $38.7 billion of assets as of December 31, 1995.
All  of  the voting  stock of  N&B Management  is owned  by individuals  who are
general partners of Neuberger&Berman.
    
   
   Theresa A. Havell is a general partner of Neuberger&Berman and a director and
Vice President of N&B Management. Ms. Havell is the Manager of the Fixed  Income
Group of Neuberger&Berman, which she established in 1984. The Fixed Income Group
manages  fixed income accounts that had approximately $11.1 billion of assets as
of December  31,  1995.  Ms.  Havell has  had  overall  responsibility  for  the
activities of the Fixed Income Group since 1984.
    
   
   Thomas  G.  Wolfe and  Theresa A.  Havell are  primarily responsible  for the
day-to-day management of AMT  Limited Maturity Bond  Investments. Mr. Wolfe  has
been  primarily  responsible for  AMT  Limited Maturity  Bond  Investments since
October 1995. Mr. Wolfe has been a Senior Portfolio Manager in the Fixed  Income
Group since July 1993, Director of Fixed Income Credit Research since July 1993,
and a Vice President of N&B Management since October 1995. From November 1987 to
June  1993 he was Vice President in the Corporate Finance Department of Standard
& Poor's Rating Group.
    
   
   N&B Management serves as distributor in  connection with the offering of  the
Limited  Maturity Bond  Portfolio's shares. In  connection with the  sale of the
Portfolio's shares, the Portfolio  has authorized the  distributor to give  only
such  information and  to make only  such statements and  representations as are
contained in the Portfolio's Prospectus.
    
 
                                                                              17
<PAGE>
   
The distributor is  responsible only  for information given  and statements  and
representations  made in the  Portfolio's Prospectus and  is not responsible for
any information given  or any  statements or  representations made  by the  Life
Companies or by brokers or salespersons in connection with Variable Contracts.
    
   
   Neuberger&Berman  acts as the principal broker  for AMT Limited Maturity Bond
Investments to the extent a broker is used in the purchase and sale of portfolio
securities and  in the  sale of  covered call  options, and  for those  services
receives  brokerage  commissions.  In  effecting  securities  transactions,  AMT
Limited Maturity Bond Investments seeks to  obtain the best price and  execution
of orders. For more information, see the SAI.
    
   The  partners and employees of Neuberger&Berman and officers and employees of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To mitigate  the possibility  that a  Series will  be adversely  affected  by
personal  trading of employees,  the Trust, Managers  Trust, N&B Management, and
Neuberger&Berman have  adopted  policies  that regulate  securities  trading  in
personal  accounts of the  portfolio managers and others  who normally come into
possession of information on portfolio  transactions. These policies comply,  in
all  material  respects,  with  the recommendations  of  the  Investment Company
Institute.

as distributor of its  shares. AMT Limited Maturity  Bond Investments bears  all
expenses  of  its  operations  other  than  those  borne  by  N&B  Management as
investment manager of the  Series. These expenses include,  but are not  limited
to, for the Portfolio and the Series, legal and accounting fees and compensation
for  trustees who  are not  affiliated with  N&B Management;  for the Portfolio,
transfer agent  fees and  the cost  of printing  and sending  reports and  proxy
materials  to shareholders; and  for the Series,  custodial fees for securities.
Any expenses  which are  not  directly attributable  to  a specific  Series  are
allocated on the basis of the net assets of the respective Series.

          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management has undertaken to limit the Limited Maturity Bond Portfolio's
expenses by reimbursing  the Portfolio for  its operating expenses  and its  pro
rata  share  of  AMT  Limited  Maturity  Bond  Investments'  operating expenses,
excluding the  compensation of  N&B Management,  taxes, interest,  extraordinary
expenses,  brokerage commissions  and transaction costs,  that exceed  1% of the
Portfolio's average  daily  net asset  value.  This undertaking  is  subject  to
termination on 60 days' prior written notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses of the Portfolio and the Series and thereby increase total return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State  Street Bank and Trust Company ("State Street"), Boston, Massachusetts,
acts as  transfer  and dividend  paying  agent  for the  Limited  Maturity  Bond
Portfolio  and in  so doing  performs certain  bookkeeping, data  processing and
administrative services. All other correspondence should be sent to State Street
Bank & Trust  Company, P.O. Box  1978, Boston, MA  02105. State Street  provides
similar  services  to  AMT  Limited Maturity  Bond  Investments  as  the Series'
transfer agent. State Street also acts as  the custodian of the Series' and  the
Portfolio's assets.
    
 
                                                                              19
<PAGE>
DISTRIBUTION AND REDEMPTION OF TRUST SHARES
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and  payments under the  Variable Contracts issued  through separate accounts of
the Life Companies which may or may not be affiliated with the Trust. Shares  of
one  Portfolio of the Trust are also offered directly to Qualified Plans. Shares
of the Trust are purchased and redeemed at net asset value.
   The Boards of  Trustees of the  Trust and Managers  Trust have undertaken  to
monitor  the Trust  and Managers Trust,  respectively, for the  existence of any
material irreconcilable conflict between the interests of the Variable  Contract
owners  of the Life  Companies and to  determine what action,  if any, should be
taken in the  event of a  conflict. The  Life Companies and  N&B Management  are
responsible for reporting any potential or existing conflicts to the Boards. Due
to  differences of tax  treatment and other  considerations, it is theoretically
possible that the interests of various Variable Contract owners participating in
the Trust and Managers Trust and  the interests of Qualified Plans investing  in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or  more Life  Company separate accounts  or Qualified Plans  might withdraw its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions will be  effected by  the separate accounts  to meet  obligations
under  the Variable Contracts and by the Qualified Plans. Contract owners do not
deal directly  with the  Trust  with respect  to  acquisition or  redemption  of
shares.  The trustees of the Trust may refuse to sell shares of any Portfolio to
any person, or suspend or terminate the  offering of shares of any Portfolio  if
such  action is required by law or by regulatory authorities having jurisdiction
or is, in the sole discretion of the trustees acting in good faith and in  light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The  Board of Trustees of  the Trust has adopted  a non-fee Distribution Plan
for each Portfolio of the Trust.
   The Distribution Plan recognizes that N&B  Management may use its assets  and
resources,  including its profits from administration  fees paid by a Portfolio,
to pay expenses associated with  the distribution of Portfolio shares.  However,
N&B  Management will  not receive  any separate fees  for such  expenses. To the
extent that any payments  made by a  Portfolio should be  deemed to be  indirect
financing  of any activity primarily intended to result in the sale of shares of
the Portfolio within the  context of Rule  12b-1 under the  1940 Act, then  such
payments shall be deemed to be authorized by the Distribution Plan.
   Under  the Distribution  Plan, the Portfolio  will require  N&B Management to
provide the Trust with quarterly reports  of the amounts expended in  connection
with  financing  any  activity  primarily  intended to  result  in  the  sale of
Portfolio shares,  and the  purpose for  which such  expenditure was  made.  The
Distribution  Plan may be terminated as to a particular Portfolio at any time by
a vote of a majority of the independent trustees of the Trust or by a vote of  a
majority   of  the  outstanding   voting  securities  of   that  Portfolio.  The
Distribution Plan does not require N&B  Management to perform any specific  type
or  level of distribution activities or to  incur any specific level of expenses
for activities  primarily  intended to  result  in the  sale  of shares  of  the
Portfolio.

DESCRIPTION OF INVESTMENTS
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Limited  Maturity  Bond Investments  may make  the following  investments, among
others, individually or in combination, although the Series may not  necessarily
buy  any or all of the  types of securities or use  any or all of the investment
techniques  that  are  described.  These  investments  may  be  limited  by  the
requirements with which the Series must comply if the Portfolio is to qualify as
regulated  investment companies  for tax purposes.  The use of  hedging or other
techniques is discretionary and no representation  is made that the risk of  AMT
Limited Maturity Bond Investments will be reduced by the techniques discussed in
this  section. For  additional information on  the following  investments and on
other types of investments the Series may make, see the SAI.
    
 
    U.S. GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities  are
obligations  of the  U.S.Treasury backed  by the  full faith  and credit  of the
United States. U.S.  Government Agency  securities are issued  or guaranteed  by
U.S.  Government agencies, instrumentalities, or other U.S. Government-sponsored
enterprises, such  as the  Government  National Mortgage  Association  ("GNMA"),
Federal  National  Mortgage  Association ("FNMA"),  Federal  Home  Loan Mortgage
Corporation ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee  Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may  be backed by the  full faith and credit of  the United States, the issuer's
ability to borrow from the U.S.  Treasury, subject to the Treasury's  discretion
in  certain cases,  or only  by the  credit of  the issuer.  U.S. Government and
Agency securities include certain mortgage-backed securities. The market  prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID  SECURITIES. The Series may  invest up to 10%  of its net assets in
securities that are illiquid, in that they cannot be expected to be sold  within
seven  days at  approximately the  price at  which they  are valued.  Due to the
absence of an  active trading market,  the Series may  experience difficulty  in
valuing  or  disposing of  illiquid  securities. N&B  Management  determines the
liquidity of  the  Series' securities,  under  supervision of  the  trustees  of
Managers Trust. Securities which are freely tradeable in their country of origin
or  in their principal market will not be considered illiquid securities even if
they are not registered for sale in the U.S.
 
   
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally outside the  U.S., including non-U.S.  governments, their  agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated in or indexed to foreign  currencies, which may also be affected  by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective of the  performance of  the underlying  investment. N&B  Management
considers  these factors  in making investments  for the Series.  The Series may
enter into forward foreign currency  contracts or futures contracts  (agreements
to  exchange one currency for  another at a future  date) and related options to
manage currency  risks and  to facilitate  transactions in  foreign  securities.
Although  these  contracts can  protect the  Series  from adverse  exchange rate
changes, they involve a risk of loss if N&B Management fails to predict  foreign
currency values correctly.
    
   Investments  in foreign securities could be affected by factors generally not
thought to be present in the U.S. Such factors include, but are not limited  to,
varying  custody, brokerage and settlement practices; difficulty in pricing some
foreign securities; less  public information about  issuers of securities;  less
governmental regulation and supervision over issuance and trading of securities;
the  unavailability of financial  information or the  difficulty of interpreting
financial  information  prepared  under   foreign  accounting  standards;   less
liquidity  and more volatility in foreign securities markets; the possibility of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or  diplomatic developments;  limitations on  the movement  of funds  or
other assets of the Series between different
 
                                                                              21
<PAGE>
countries;   difficulties  in  invoking  legal   process  abroad  and  enforcing
contractual obligations;  and the  difficulty of  assessing economic  trends  in
foreign  countries.  Investment  in  foreign  securities  also  involves  higher
brokerage and custodian expenses than does investment in domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve other  risks  which are  not  ordinarily associated  with  investing  in
domestic  securities. These risks include changes in currency exchange rates and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions   applicable  to  such  investments   or  devaluations  of  foreign
currencies. A decline  in the exchange  rate would reduce  the value of  certain
portfolio   securities  irrespective  of  the   performance  of  the  underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and changes in  rates of exchange  with the U.S.  dollar because the  underlying
security  is usually denominated in foreign currency. All of the foregoing risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN CURRENCY TRANSACTIONS.  The Series  may enter  into forward  foreign
currency  exchange  contracts in  order to  protect  against adverse  changes in
future foreign currency  exchange rates, to  facilitate transactions in  foreign
securities  and to  repatriate dividend or  interest income  received in foreign
currencies. The Series may enter  into contracts to purchase foreign  currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends  to purchase. The Series  may also enter into  contracts to sell foreign
currencies to  protect  against a  decline  in  value of  its  foreign  currency
denominated  portfolio  securities due  to  a decline  in  the value  of foreign
currencies against the  U.S. dollar.  Contracts to sell  foreign currency  could
limit  any potential gain which might be realized  by the Series if the value of
the hedged currency increased.
   The Series may also  enter into forward  foreign currency exchange  contracts
for  non-hedging  purposes  when  the investment  adviser  anticipates  that the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated  in that currency do not present attractive investment opportunities
and are not held in the Series.  The Series may also engage in cross-hedging  by
using  forward contracts  in one currency  to hedge against  fluctuations in the
value of  securities  denominated in  a  different currency  if  the  investment
adviser  believes  that  there  is  a pattern  of  correlation  between  the two
currencies.
   If the  Series enters  into  a forward  currency  exchange contract  to  sell
foreign  currency, it may  be required to  place cash or  high grade liquid debt
securities in  a segregated  account in  an amount  equal to  the value  of  the
Series'  total assets  committed to  the consummation  of the  forward contract.
Although these contracts  can protect  the Series from  adverse exchange  rates,
they  involve risk of loss  if N&B Management fails  to predict foreign currency
values correctly.
 
    PUT AND CALL OPTIONS, FUTURES  CONTRACTS, OPTIONS ON FUTURES CONTRACTS.  The
Series  may  try to  reduce  the risk  of  securities price  changes  (hedge) or
generate income by  writing (selling)  covered call  options against  securities
held  in its portfolio having a market value not exceeding 10% of its net assets
and may purchase call options in related closing transactions. The purchaser  of
a  call option acquires the  right to buy a portfolio  security at a fixed price
during a  specified period.  The maximum  price the  seller may  realize on  the
security  during the option period  is the fixed price.  The seller continues to
bear the  risk of  a decline  in the  security's price,  although this  risk  is
reduced by the premium received for the option.
   
   The  Series also may  try to manage  portfolio duration by  (1) entering into
interest-rate futures contracts traded on  futures exchanges and (2)  purchasing
and writing options on futures contracts.
    
   
   The  Series also may try  to reduce the risk  of securities price changes and
expected changes in  prevailing currency  exchange rates (hedge)  and may  write
covered  call  options  and  purchase  put options  on  debt  securities  in its
portfolio
    
 
22
<PAGE>
   
or on foreign currencies  for hedging purposes or  for the purpose of  producing
income.  The Series will write call options on a security or currency only if it
holds that security  or currency  or has  the right  to obtain  the security  or
currency  at  no additional  cost.  These investment  practices  involve certain
risks, including transactional expense,  price volatility and  a high degree  of
leverage. The Series may engage in transactions in futures contracts and related
options  only  as  permitted by  regulations  of the  Commodity  Futures Trading
Commission.
    
   
   The writing and purchasing of options is a highly specialized activity  which
involves  investment techniques and  risks different from  those associated with
ordinary portfolio  securities  transactions  including  transactional  expense,
price  volatility and a  high degree of  leverage. The writing  of options could
result in significant increases in the Series' turnover rate.
    
   The primary  risks in  using put  and call  options, futures  contracts,  and
options  on futures contracts, and forward foreign currency contracts or options
on foreign currencies ("Hedging Instruments")  are (1) imperfect correlation  or
no  correlation between changes  in market value  of the securities  held by the
Series and the prices of the Hedging Instruments; (2) possible lack of a  liquid
secondary  market for Hedging  Instruments and the  resulting inability to close
out a Hedging Instrument when  desired; (3) the fact  that the skills needed  to
use  Hedging Instruments are  different from those needed  to select the Series'
securities; (4) the  fact that, although  use of these  instruments for  hedging
purposes  can reduce the risk of loss,  they also can reduce the opportunity for
gain, or  even result  in losses,  by offsetting  favorable price  movements  in
hedged  investments; and (5) the possible inability of the Series to purchase or
sell a security at a time that would otherwise be favorable for it to do so,  or
the  possible need for the Series to  sell a security at a disadvantageous time,
due to its  need to maintain  "cover" or to  segregate securities in  connection
with its use of these instruments. Futures, options and forward foreign currency
contracts are considered derivatives.
   
    FORWARD  COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or forward
commitment transaction, the Series  commits to purchase  securities in order  to
secure  an advantageous price and  yield at the time  of the commitment and pays
for the securities when  they are delivered at  a future date (generally  within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity  to obtain  a favorable price  and yield.  When-issued securities or
securities subject to  a forward  commitment may  decline or  increase in  value
during  the period from  the Series' investment commitment  to the settlement of
the purchase which may magnify fluctuation in the Series' NAV.
    
 
    INDEXED SECURITIES. The Series may invest in indexed securities whose  value
is  linked  to  currencies,  interest  rates,  commodities,  indices,  or  other
financial indicators.  Most indexed  securities are  short-to-intermediate  term
fixed-income  securities whose values at maturity or interest rates rise or fall
according to the change in one or more specified underlying instruments. Indexed
securities may  be  positively or  negatively  indexed (i.e.,  their  value  may
increase  or decrease  if the underlying  instrument appreciates),  and may have
return  characteristics  similar  to   direct  investments  in  the   underlying
instrument  or  to one  or more  options on  the underlying  instrument. Indexed
securities may be more volatile than the underlying instrument itself.
 
   
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements and lend securities  from its portfolio.  In a repurchase  agreement,
the  Series buys a security from a  Federal Reserve member bank, or a securities
dealer and  simultaneously agrees  to  sell it  back at  a  higher price,  at  a
specified  date, usually less than a  week later. The underlying securities must
fall within the Series' investment policies and limitations (but not limitations
as to maturity or  duration). The Series also  may lend portfolio securities  to
banks, brokerage firms, or institutional investors to earn income. Costs, delays
or  losses could result  if the selling  party to a  repurchase agreement or the
borrower of portfolio  securities becomes  bankrupt or  otherwise defaults.  N&B
Management monitors the creditworthiness of sellers and borrowers.
    
 
                                                                              23
<PAGE>
   
    REVERSE  REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.  In a  reverse repurchase
agreement, the Series sells securities to a bank or securities dealer and at the
same time agrees to repurchase  the same securities at a  later date at a  fixed
price.  During the period before the repurchase, the Series continues to receive
principal and interest payments on the securities. In a dollar roll, the  Series
sells  securities for delivery in the current month and simultaneously contracts
to repurchase  substantially similar  (same  type and  coupon) securities  on  a
specified  future  date  from  the  same party.  During  the  period  before the
repurchase,  the  Series  forgoes  principal   and  interest  payments  on   the
securities.  The Series  is compensated  by the  difference between  the current
sales price and the forward price for the future purchase (often referred to  as
the  "drop"), as  well as  by the interest  earned on  the cash  proceeds of the
initial sale. Reverse repurchase  agreements and dollar  rolls may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements and dollar rolls.
    
 
    MORTGAGE-BACKED SECURITIES. Mortgage-backed  securities represent  interests
in,  or are  secured by  and payable  from, pools  of mortgage  loans, including
collateralized mortgage  obligations. These  securities may  be U.S.  Government
mortgage-backed  securities, which are issued or guaranteed by a U.S. Government
agency or instrumentality (though not necessarily  backed by the full faith  and
credit  of the United States), such as  GNMA, FNMA and FHLMC certificates. Other
mortgage-backed securities are issued by private issuers, generally  originators
of  and investors  in mortgage  loans, including  savings associations, mortgage
bankers, commercial  banks, investment  bankers, and  special purpose  entities.
These  private mortgage-backed  securities may  be supported  by U.S. Government
mortgage-backed securities or  some form of  non-government credit  enhancement.
Mortgage-backed  securities may have either  fixed or adjustable interest rates.
Tax or regulatory changes may  adversely affect the mortgage securities  market.
In  addition, changes in  the market's perception  of the issuer  may affect the
value of  mortgage-backed  securities. The  rate  of return  on  mortgage-backed
securities  may be affected by prepayments of principal on the underlying loans,
which generally increase as interest rates  decline; as a result, when  interest
rates  decline,  holders  of  these  securities  normally  do  not  benefit from
appreciation in market value to the same extent as holders of other non-callable
debt securities. N&B Management  determines the effective  life and duration  of
mortgage-backed  securities  based  on  industry  practice  and  current  market
conditions. If N&B Management's determination is  not borne out in practice,  it
could  positively  or negatively  affect  the value  of  the Series  when market
interest rates change.  Increasing market  interest rates  generally extend  the
effective maturities of mortgage-backed securities.
 
    ASSET-BACKED  SECURITIES. Asset-backed securities represent interests in, or
are secured  by  and payable  from  pools of  assets,  such as  consumer  loans,
CARS-SM-  ("Certificates  for Automobile  Receivables"), credit  card receivable
securities, and installment  loan contracts.  Although these  securities may  be
supported by letters of credit or other credit enhancements, payment of interest
and  principal ultimately depends upon  individuals paying the underlying loans.
The risk  that  recovery on  repossessed  collateral might  be  unavailable,  or
inadequate to support payments on asset-backed securities is greater than in the
case of mortgage-backed securities.
   
    SHORT SELLING. The Series may make short sales against-the-box. A short sale
is  "against-the-box" when, at all times during  which a short position is open,
the Series owns an equal amount of such securities, or owns securities giving it
the right, without payment of future consideration, to obtain an equal amount of
securities sold short.
    
 
    VARIABLE AND FLOATING RATE SECURITIES. Variable and floating rate securities
have interest  rate adjustment  formulas  that help  to stabilize  their  market
value.  Many  of these  instruments  carry a  demand  feature which  permits the
 
24
<PAGE>
Series to sell them during  a determined time period  at par value plus  accrued
interest.  The demand feature is often backed  by a credit instrument, such as a
letter of credit,  or by a  creditworthy insurer.  The Series may  rely on  such
instrument  or the creditworthiness  of the insurer in  purchasing a variable or
floating rate security.
 
    ZERO  COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay   interest
currently;  instead, they are sold  at a discount from  their face value and are
redeemed at face value when  they mature. Because zero  coupon bonds do not  pay
current income, their prices can be very volatile when interest rates change. In
calculating  its daily  income, the Series  accrues a portion  of the difference
between a zero coupon bond's purchase price and its face value.
 
    MUNICIPAL OBLIGATIONS. Municipal obligations are  issued by or on behalf  of
states, the District of Columbia, and U.S. territories and possessions and their
political   subdivisions,  agencies,  and  instrumentalities.  The  interest  on
municipal obligations is exempt from  federal income tax. Municipal  obligations
include  "general obligation"  securities, which are  backed by  the full taxing
power of  a municipality,  and "revenue"  securities, which  are backed  by  the
income  from a  specific project, facility,  or tax.  Municipal obligations also
include industrial development  and private  activity bonds --  the interest  on
which  may be  a tax  preference item  for purposes  of the  federal alternative
minimum tax -- which are  issued by or on behalf  of public authorities and  are
not  backed by the credit of any governmental or public authority. "Anticipation
notes" are issued by municipalities in  expectation of future proceeds from  the
issuance  of bonds, or from taxes or  other revenues, and are payable from those
bond proceeds, taxes, or revenues. Municipal obligations also include tax-exempt
commercial paper, which is issued  by municipalities to help finance  short-term
capital  or operating requirements.  Current efforts to  restructure the federal
budget and the relationship between the  federal government and state and  local
governments  may impact the  financing of some  issuers of municipal securities.
Some states and localities are experiencing substantial deficits and may find it
difficult for  political or  economic  reasons to  increase taxes.  Efforts  are
underway  that may result in a "flat  tax" or other restructuring of the federal
income tax system. These  developments could reduce the  value of all  municipal
securities, or the securities of particular issuers.
 
    RESTRICTED  SECURITIES AND  RULE 144A SECURITIES.  The Series  may invest in
restricted securities and Rule 144A securities. Restricted securities cannot  be
sold  to the public without registration under the Securities Act of 1933 ("1933
Act"). Unless  registered  for  sale,  these securities  can  be  sold  only  in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted  securities are generally considered  illiquid. Rule 144A securities,
although not registered, may be resold only to qualified institutional buyers in
accordance with Rule 144A under the  1933 Act. Unregistered securities may  also
be  sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.
 
                                                                              25

responsible  for all information or lack of information about that Portfolio and
Series in the SAI, and no other Portfolio or Series is responsible therefor. The
trustees of  the Trust  and of  Managers Trust  have considered  this factor  in
approving each Portfolio's and Series' use of a single combined SAI.

ADVISERS MANAGEMENT TRUST
 
          Liquid Asset Portfolio
 
- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance  policies  ("Variable  Contracts").  Shares of  the  one  of  the
Portfolios  are also offered directly to  qualified pension and retirement plans
("Qualified Plans").
   THIS  PROSPECTUS  CONTAINS  INFORMATION   PERTAINING  TO  THE  LIQUID   ASSET
PORTFOLIO ONLY.

   EACH  PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS CORRESPONDING
SERIES (EACH  A "SERIES")  OF  ADVISERS MANAGERS  TRUST ("MANAGERS  TRUST"),  AN

ASSET   PORTFOLIO'S  CORRESPONDING  SERIES,  IS  MANAGED  BY  NEUBERGER&  BERMAN
MANAGEMENT INCORPORATED ("N&B MANAGEMENT"). AMT LIQUID ASSET INVESTMENTS INVESTS
IN  SECURITIES  IN  ACCORDANCE  WITH  AN  INVESTMENT  OBJECTIVE,  POLICIES,  AND
LIMITATIONS  IDENTICAL TO  THOSE OF THE  LIQUID ASSET  PORTFOLIO. THE INVESTMENT
PERFORMANCE OF  THE LIQUID  ASSET PORTFOLIO  WILL DIRECTLY  CORRESPOND WITH  THE
INVESTMENT  PERFORMANCE  OF AMT  LIQUID  ASSET INVESTMENTS.  THIS "MASTER/FEEDER
FUND" STRUCTURE IS DIFFERENT FROM THAT OF MANY OTHER INVESTMENT COMPANIES  WHICH
DIRECTLY  ACQUIRE  AND  MANAGE  THEIR OWN  PORTFOLIOS  OF  SECURITIES.  FOR MORE

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and  limitations  that  are  identical  to  those  of  the  respective
Portfolio.  The trustees  of the  Trust believe  that this  "master/feeder fund"
structure may benefit shareholders. For more information about the  organization
of   the  Portfolios  and   the  Series,  including   certain  features  of  the
master/feeder fund structure, see  "Special Information Regarding  Organization,
Capitalization,  and Other Matters" on page 9. For more details about AMT Liquid
Asset Investments, its investments and their risks, see "Investment Program"  on
page  6,  "Ratings  of  Securities"  on page  6,  "Borrowings"  on  page  7, and
"Description of Investments" on page 19.
    
   Here is a summary of important features of the Liquid Asset Portfolio and its
corresponding Series. Of course,  there can be no  assurance that the  Portfolio
will meet its investment objective.

          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An  investment in  any Portfolio involves  certain risks,  depending upon the
types of  investments made  by its  corresponding Series.  Special risk  factors
apply  to  investments which  may be  made  by AMT  Liquid Asset  Investments in
foreign securities and zero coupon  bonds. AMT Liquid Asset Investments  invests
in  fixed income securities, the value of which is likely to decline in times of
rising interest rates and rise in  times of falling interest rates. In  general,
the  longer the maturity of a fixed  income security, the more pronounced is the
effect of a change in interest rates on the value of the security.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B Management,  with  the  assistance of  Neuberger&Berman  as  sub-adviser,
selects  investments  for  AMT  Liquid Asset  Investments.  N&B  Management also
provides administrative services to AMT Liquid Asset Investments and the  Liquid
Asset  Portfolio and  acts as  distributor of the  shares of  the Portfolio. See
"Management and Administration" in this Prospectus.

  NOTES:
   
1)The per share amounts and ratios which are shown reflect income and  expenses,
  including  the  Portfolio's  proportionate  share of  the  Series'  income and
  expenses.
    
   
2)Since  the  commencement  of  operations,  N&B  Management  or  the  principal
  underwriter voluntarily assumed certain operating expenses of the Portfolio as
  described  in Note B of  Notes to Financial Statements  and in this Prospectus
  under  "Expense  Limitation."  Had  such  action  not  been  undertaken,   the
  annualized  ratios of expenses and net  investment income to average daily net
  assets would  have been  1.25% and  4.66%, respectively,  for the  year  ended
  December 31, 1995, 1.03% and 3.27% in 1994, 1.03% and 8.25% in 1989, 1.25% and
  6.27%  in  1988,  1.52%  and  5.17%  in 1987  and  2.74%  and  3.59%  in 1986,
  respectively. There was no reduction of expenses for the years ended  December
  31, 1990 through and including 1993.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in  net asset value  on the performance  of the Portfolio  during each year and
 assumes dividends  and capital  gain distributions,  if any,  were  reinvested.
 Results  represent  past  performance  and  do  not  guarantee  future results.
 Investment returns and principal may fluctuate and shares when redeemed may  be
 worth  more or less  than original cost.  Total return figures  would have been
 lower if N&B Management had not  reimbursed certain expenses. The total  return
 information  shown does not reflect expenses that apply to the separate account
 or the related insurance policies, and inclusion of these charges would  reduce
 the total return figures for all years shown.

INVESTMENT PROGRAM
    
   
   The investment policies and limitations of the Liquid Asset Portfolio and AMT
Liquid  Asset Investments are identical. The Liquid Asset Portfolio invests only
in AMT Liquid Asset Investments. Therefore, the following shows you the kinds of
securities in which AMT Liquid Asset Investments invests. For an explanation  of
some types of investments, see "Description of Investments" on page 19.
    
   Investment  policies and  limitations of the  Liquid Asset  Portfolio and AMT
Liquid Asset Investments are not fundamental unless otherwise specified in  this
Prospectus  or  the SAI.  While a  non-fundamental policy  or limitation  may be
changed by the trustees  of the Trust or  of Managers Trust without  shareholder
approval,  the  Liquid Asset  Portfolio  intends to  notify  shareholders before
making any material change to such policies or limitations. Fundamental policies
and limitations may not be changed without shareholder approval. There can be no
assurance that AMT Liquid Asset Investments and the Liquid Asset Portfolio  will
achieve  their  objectives.  The Liquid  Asset  Portfolio, by  itself,  does not
represent a comprehensive investment program.
   
   Additional investment techniques,  features, and  limitations concerning  AMT
Liquid Asset Investments' investment program are described in the SAI.
    
 
          AMT Liquid Asset Investments
 
- --------------------------------------------------------------------------------
 
   The investment objective of AMT Liquid Asset Investments and the Liquid Asset
Portfolio  is to provide  the highest current income  consistent with safety and
liquidity. This  investment objective  is  fundamental and  may not  be  changed
without  the approval of the holders of  a majority of the outstanding shares of
the Portfolio and Series.
   AMT Liquid Asset Investments invests in a portfolio of debt instruments  with
remaining maturities of 397 days or less and maintains a dollar-weighted average
portfolio  maturity of not more than 90 days. The Series uses the amortized cost
method of valuation  to enable the  Portfolio to maintain  a stable $1.00  share
price, which means that while Portfolio shares earn income, they should be worth
the  same when the shareholder sells them  as when the shareholder buys them. Of
course, there is  no guarantee that  the Portfolio  will be able  to maintain  a
$1.00 share price.
   AMT  Liquid Asset Investments invests in high quality U.S. dollar-denominated
money market instruments of U.S. and foreign issuers, including governments  and
their  agencies and  instrumentalities, banks and  other financial institutions,
and corporations, and may invest in repurchase agreements with respect to  these
instruments.  The Series  may invest  25% or  more of  its total  assets in U.S.
Government and  Agency securities  or  in certificates  of deposit  or  bankers'
acceptances issued by domestic branches of U.S. banks.
 
          Short-Term Trading
 
- --------------------------------------------------------------------------------
 
   While  AMT Liquid  Asset Investments  does not  purchase securities  with the
intention of profiting from short-term trading, it may sell portfolio securities
prior to  maturity when  the investment  adviser believes  that such  action  is
advisable.
 
          Ratings of Securities
 
- --------------------------------------------------------------------------------
 
    HIGH  QUALITY DEBT SECURITIES.  High quality debt  securities are securities
that have received a rating from at least one nationally recognized  statistical
rating  organization ("NRSRO"), such as Standard  & Poor's Ratings Group ("S&P")
or Moody's Investors Service, Inc. ("Moody's"), in one of the two highest rating
categories (the highest  category in the  case of commercial  paper) or, if  not
rated    by    any    NRSRO,    such    as    U.S.    Government    and   Agency
 
6
<PAGE>
securities, have been determined by N&B Management to be of comparable  quality.
If  a security has been rated  by two or more NRSROs,  at least two of them must
have given the  security a high  quality rating  in order for  AMT Liquid  Asset
Investments to invest in that security.
   If   the  quality  of  securities  held   by  AMT  Liquid  Asset  Investments
deteriorates so that the securities would  no longer satisfy its standards,  AMT
Liquid  Asset Investments,  in accordance  with Rule  2a-7 under  the Investment
Company Act of 1940, will consider disposing of its securities.
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT Liquid Asset Investments has a fundamental policy that it may not  borrow
money, except that it may (1) borrow money from banks for temporary or emergency
purposes  and  not  for leveraging  or  investment  and (2)  enter  into reverse
repurchase agreements  for any  purpose,  so long  as  the aggregate  amount  of
borrowings  and reverse repurchase  agreements does not  exceed one-third of the
Series' total assets  (including the  amount borrowed)  less liabilities  (other
than   borrowings).  The  Series   does  not  expect  to   borrow  money.  As  a
non-fundamental policy,  the Series  may purchase  portfolio securities  if  its
outstanding  borrowings, including  reverse repurchase agreements,  exceed 5% of
its total assets.
   Currently, the State of California imposes borrowing limitations on  variable
insurance  product funds.  To comply  with these  limitations, the  Series, as a
matter of operating policy, has undertaken that it will not borrow more than 10%
of its net  asset value  when borrowing  for any  general purpose  and will  not
borrow  more  than 25%  of its  net asset  value when  borrowing as  a temporary
measure to facilitate redemptions.  For these purposes, net  asset value is  the
market  value of all investments or assets owned less outstanding liabilities at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For temporary  defensive  purposes, AMT  Liquid  Asset Investments  may  each
invest  up  to 100%  of  its total  assets in  cash  and cash  equivalents, U.S.
Government and  Agency  Securities, commercial  paper  and certain  other  money
market  instruments,  as well  as  repurchase agreements  collateralized  by the
foregoing. Also, for temporary defensive purposes, AMT Liquid Asset  Investments
may adopt shorter weighted average maturity than normal.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.
 
                                                                               7

PERFORMANCE INFORMATION
   From  time  to  time, the  Liquid  Asset Portfolio's  annualized  "yield" and
"effective yield" may be presented  in advertisements and sales literature.  The
Portfolio's  "yield" represents an annualization of  the increase in value of an
account (excluding any capital changes) invested in the Portfolio for a specific
seven-day period. The Portfolio's "effective  yield" compounds such yield for  a
year and thus is greater than the Portfolio's yield.
   
   All  performance information  presented for  the Portfolio  is based  on past
performance and does not predict  future performance. Any Portfolio  performance
information  presented  will  also  include  or  be  accompanied  by performance
information for the Life Company separate accounts investing in the Trust  which
will  take  into  account  insurance-related  charges  and  expenses  under such
insurance policies and contracts. Further information regarding the  Portfolio's
performance  is presented in the Trust's annual report to shareholders, which is
available without charge by calling 800-366-6264.
    
   Advertisements concerning  the  Trust  may  from time  to  time  compare  the
performance of the Portfolio to various indices. Advertisements may also contain
the  performance  rankings  assigned the  Portfolio  or its  adviser  by various
publications and  statistical services.  Any such  comparisons or  rankings  are
based  on  past  performance  and  the  statistical  computations  performed  by
publications and  services,  and  are  not  necessarily  indications  of  future
performance.  Because the Portfolio is a managed investment vehicle investing in
a wide variety  of securities, the  securities owned by  the Portfolio will  not
match  those  making up  an index.  Please note  that indices  do not  take into
account any fees  and expenses of  investing in the  individual securities  that
they track and that individuals cannot invest in any index.

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each  Portfolio is a separate series of  the Trust, a Delaware business trust
organized pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust  is
registered  under  the Investment  Company Act  of  1940 (the  "1940 Act")  as a
diversified, open-end management investment company, commonly known as a  mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of one Portfolio which as of December 31, 1995 had not yet commenced  investment
operations.   These  conversions  were  approved  by  the  shareholders  of  the
predecessors of the Portfolios in August 1994. Each Portfolio invests all of its
net investable assets  in its  corresponding Series,  in each  case receiving  a
beneficial  interest in  that Series.  The trustees  of the  Trust may establish
additional  portfolios  or   classes  of   shares,  without   the  approval   of
shareholders.  The assets of  each Portfolio belong only  to that Portfolio, and
the liabilities of  each Portfolio  are borne solely  by that  Portfolio and  no
other.
    
   
    DESCRIPTION  OF SHARES. Each  Portfolio is authorized  to issue an unlimited
number of shares of beneficial interest (par value $0.001 per share). Shares  of
each  Portfolio represent  equal proportionate interests  in the  assets of that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law, and shareholders  have no  preemptive or other  right to  subscribe to  any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings  of  shareholders of  the Portfolios.  The  trustees will  call special
meetings of shareholders of a Portfolio only  if required under the 1940 Act  or
in their discretion or upon the written request of holders of 10% or more of the
outstanding  shares  of that  Portfolio entitled  to  vote. Pursuant  to current
interpretations of  the  1940  Act,  the  Life  Companies  will  solicit  voting
instructions  from Variable Contract owners with respect to any matters that are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any  Portfolio; a  shareholder is  entitled to  the same  limitation of personal
liability extended to shareholders  of corporations. To  guard against the  risk
that  Delaware law might  not be applied  in other states,  the Trust Instrument
requires that every  written obligation of  the Trust or  a Portfolio contain  a
statement  that such obligation may  be enforced only against  the assets of the
Trust or Portfolio and  provides for indemnification out  of Trust or  Portfolio
property  of any  shareholder nevertheless held  personally liable  for Trust or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   
   Each Series is a  separate series of  Managers Trust, a  New York common  law
trust  organized as of May 24, 1994. Managers Trust is registered under the 1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International  Portfolio which  as of  December 31,  1995 had  not yet commenced
investment   operations)   invested   all   of   its   net   investable   assets
    
 
                                                                               9
<PAGE>
   
(cash,  securities, and receivables  relating to securities)  in a corresponding
Series of Managers Trust,  receiving a beneficial interest  in that Series.  The
assets  of each Series belong  only to that Series,  and the liabilities of each
Series are borne solely by that Series and no other.
    
   
    PORTFOLIOS' INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve  its
investment  objective  by investing  all  of its  net  investable assets  in its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities  and  its corresponding  Portfolio acquires  an indirect  interest in
those securities. Historically, N&B Management, administrator to the  Portfolios
and  investment  manager of  all  Series has  sponsored,  with Neuberger&Berman,
traditionally structured funds since  1950. However, it  has operated 12  master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each  Portfolio's investment in its corresponding Series  is in the form of a
non-transferable beneficial  interest. Members  of the  general public  may  not
purchase  a direct interest in the Series. Currently, each Portfolio is the sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily   limited  to  the  managed  separate  accounts  of  life  insurance
companies, to invest in the Series. All  investors will invest in the Series  on
the  same terms and  conditions as the  Portfolios and will  pay a proportionate
share of the expenses  of the Series.  The Portfolios do  not sell their  shares
directly  to members of the general public.  Other investors in the Series would
not be required to sell their shares at the same offering price as a  Portfolio,
could  have a  different administration fee  and expenses than  a Portfolio, and
might charge  a sales  commission. Therefore,  Portfolio shareholders  may  have
different  returns than shareholders in  another entity that invests exclusively
in the Series.
   A Portfolio's investment in its corresponding  Series may be affected by  the
actions  of other large investors in the Series, if any. For example, if a large
investor in  the Series  other than  a Portfolio  redeemed its  interest in  the
Series,  the Series' remaining  investors (including the  Portfolio) might, as a
result, experience higher pro rata  operating expenses, thereby producing  lower
returns.
   Each  Portfolio  may withdraw  its entire  investment from  its corresponding
Series at any time,  if the trustees of  the Trust determine that  it is in  the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw,  for example, if there  were other investors in  the Series with power
to, and who did by a vote of all investors (including the Portfolio), change the
investment objective, policies,  or limitations of  the Series in  a manner  not
acceptable  to  the  trustees of  the  Trust.  A withdrawal  could  result  in a
distribution in kind of  securities (as opposed to  a cash distribution) by  the
Series.  That  distribution  could result  in  a less  diversified  portfolio of
investments for the Portfolio  and could affect adversely  the liquidity of  the
Portfolio's  investment  portfolio.  If  a Portfolio  decided  to  convert those
securities to cash, it usually would  incur brokerage fees or other  transaction
costs.  If a  Portfolio withdrew  its investment  from the  Series, the trustees
would consider what action  might be taken, including  the investment of all  of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the  Portfolio of its own investment manager  to manage its assets in accordance
with its investment objective, policies,  and limitations. The inability of  the
Portfolio  to find  a suitable  replacement could  have a  significant impact on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors except as required by the 1940  Act. Each investor in the Series  will
be  entitled to vote  in proportion to  its relative beneficial  interest in the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act and  other  applicable  law,  a Portfolio  will  solicit  proxies  from  its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
10
<PAGE>
Portfolio's  shareholders. Pursuant to current  interpretations of the 1940 Act,
the Life Companies  who are shareholders  of the Portfolio  will solicit  voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there  can be no assurance that any issue  that receives a majority of the votes
cast by Portfolio  shareholders will  receive a majority  of votes  cast by  all
Series  investors; indeed,  if other investors  hold a majority  interest in the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be liable  for all  obligations of  the Series,  but not  of the  other  Series.
However,  the risk  of an  investor in  the Series  incurring financial  loss on
account of such liability would be limited to circumstances in which the  Series
had  inadequate insurance  and was  unable to  meet its  obligations out  of its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.
 
                                                                              11
<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net asset  value  ("NAV")  per  share.  The NAVs  for  each  Portfolio  and  its
corresponding Series are calculated by subtracting liabilities from total assets
(in  the case of the Series, the market value of the securities the Series holds
plus cash and other assets; in the case of a Portfolio, its percentage  interest
in  its  corresponding Series,  multiplied by  the Series'  NAV, plus  any other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number of Portfolio shares  outstanding and rounding the  result to the  nearest
full cent.
   
   AMT  Liquid Asset  Investments, in accordance  with Rule 2a-7  under the 1940
Act, will use the amortized cost method of valuation to enable the Series to try
to maintain a stable NAV of $1.00 per share. AMT Liquid Asset Investments values
its securities at  their cost at  the time  of purchase and  assumes a  constant
amortization to maturity of any discount or premium.

<PAGE>
DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   The  Liquid Asset Portfolio distributes to its shareholders substantially all
of its share of AMT Liquid Asset Investments' net investment income (net of  the
Portfolio's  expenses)  and net  realized  capital gains.  Income  dividends are
declared daily for the Portfolio at the time its NAV is calculated and are  paid
monthly,  and  net  realized capital  gains,  if any,  are  normally distributed
annually in February.
   
   The Liquid Asset Portfolio offers its  shares solely to separate accounts  of
the Life Companies. All dividends and other distributions are distributed to the
separate  accounts and will be automatically invested in Trust shares. Dividends
and other  distributions made  by the  Portfolio to  the separate  accounts  are
taxable, if at all, to the extent described in the prospectuses for the Variable
Contracts.
    
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each  Portfolio  is  treated as  a  separate  entity for  Federal  income tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment  company" under Subchapter M of the Internal Revenue Code of 1986, as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income, net short-term capital gain and net gains from certain foreign  currency
transactions)  and net  capital gain (the  excess of net  long-term capital gain
over net short-term capital loss) that is distributed to its shareholders.  Each
Portfolio  intends  to  distribute  all  of its  net  income  and  gains  to its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service that  each  Portfolio, as  an  investor  in a  corresponding  Series  of
Managers  Trust, will  be deemed  to own  a proportionate  share of  the Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will be treated as  a separate partnership for  Federal income tax purposes  and
will  not be a "publicly traded partnership," with the result that none of those
Series will  be subject  to  Federal income  tax  (and, instead,  each  investor
therein  will take into account in  determining its Federal income tax liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The foregoing is only a summary of  some of the important Federal income  tax
considerations  generally affecting  the Portfolios and  their shareholders; see
the SAI for a  more detailed discussion. Prospective  shareholders are urged  to
consult their tax advisers.
 
                                                                              13
<PAGE>
SPECIAL CONSIDERATIONS
   
   The  Portfolios serve  as the  underlying investments  for Variable Contracts
issued through separate accounts of the Life  Companies which may or may not  be
affiliated.   See  "Distribution  and  Redemption   of  Trust  Shares"  in  this
Prospectus.
    
   
   Section 817(h) of the Code  imposes certain diversification standards on  the
underlying  assets of segregated asset accounts  that fund contracts such as the
Variable Contracts (that is, the assets of the Series), which are in addition to
the diversification requirements imposed on the  Portfolios by the 1940 Act  and
Subchapter  M. Failure to satisfy those  standards would result in imposition of
Federal income tax on a Variable Contract owner with respect to the increase  in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset  account that funds contracts such as the Variable Contracts is treated as
meeting the  diversification standards  if, as  of the  close of  each  calendar
quarter,  the assets in the account  meet the diversification requirements for a
regulated investment company  and no more  than 55% of  those assets consist  of
cash,  cash items, U.S. Government securities  and securities of other regulated
investment companies.
    
   The Treasury Regulations amplify the  diversification standards set forth  in
Section  817(h) and  provide an  alternative to  the provision  described above.
Under the  regulations,  an  investment  portfolio  will  be  deemed  adequately
diversified  if (i) no  more than 55%  of the value  of the total  assets of the
portfolio is represented by any  one investment; (ii) no  more than 70% of  such
value  is represented  by any two  investments; (iii)  no more than  80% of such
value is represented by any three investments; and (iv) no more than 90% of such
value is represented by any four investments. For purposes of these  Regulations
all  securities of the same issuer are  treated as a single investment, but each
United States  government  agency  or  instrumentality shall  be  treated  as  a
separate issuer.
   
   Each  Series  will be  managed  with the  intention  of complying  with these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section 817  of the  Code  and the  Treasury  Regulations thereunder  do  not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder fund structure. As described  under "Tax Status" above, the  Trust
and  Managers Trust  have received  a ruling  from the  Internal Revenue Service
concluding that the "look-through" rule of  Section 817, which would permit  the
segregated  asset  accounts to  look  through to  the  underlying assets  of the
Series, will be available for the variable contract diversification test.
    
   Currently, the State  of California imposes  diversification requirements  on
variable  insurance products funds investing in non-U.S. securities. Under these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must be invested in at least five countries; less than 80% but at least 60%,  in
at  least four  countries; less  than 60% but  at least  40%, in  at least three
countries; and less than 40% but at least 20%, in at least two countries, except
that up to  35% of  a fund's  assets may be  invested in  securities of  issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United  Kingdom or Germany. The  Trust and Managers Trust  intend to comply with
the California diversification requirements, to the extent applicable.

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The trustees  of  the Trust  and  the trustees  of  Managers Trust,  who  are
currently  the same individuals, have  overall responsibility for the operations
of each  Portfolio  and each  Series,  respectively. The  SAI  contains  general
background  information  about each  trustee  and officer  of  the Trust  and of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or directors of  N&B Management  and/or partners  of Neuberger&Berman  serve
without  compensation from  the Portfolios  or the  Series. The  trustees of the
Trust and of Managers Trust, including a majority of those trustees who are  not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written  procedures reasonably appropriate  to deal with  potential conflicts of
interest, including,  if necessary,  creating a  separate board  of trustees  of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management  serves  as  the  investment  manager  of  AMT  Liquid  Asset
Investments, as administrator of the  Liquid Asset Portfolio and as  distributor
of  the shares of the Liquid Asset Portfolio. N&B Management and its predecessor
firms have specialized in the management of no-load mutual funds since 1950.  In
addition  to  serving the  Series of  Managers  Trust, N&B  Management currently
serves as  investment  manager or  investment  adviser of  other  mutual  funds.
Neuberger&Berman,  which acts  as sub-adviser  for the  Series and  other mutual
funds managed by  N&B Management,  also serves  as investment  adviser of  three
other   investment  companies.   These  funds   had  aggregate   net  assets  of
approximately $11.9 billion as of December 31, 1995.
    
   
   As sub-adviser,  Neuberger&Berman furnishes  N&B Management  with  investment
recommendations  and  research information  without  added cost  to  the Series.
Neuberger&Berman is a member firm of the NYSE and other principal exchanges  and
acts  as the  Series' principal  broker to the  extent a  broker is  used in the
purchase and sale of portfolio securities and the sale of covered call  options.
Neuberger&Berman and its affiliates, including N&B Management, manage securities
accounts that had approximately $38.7 billion of assets as of December 31, 1995.
All  of  the voting  stock of  N&B Management  is owned  by individuals  who are
general partners of Neuberger&Berman.
    
   
   Theresa A. Havell is a general partner of Neuberger&Berman and a director and
Vice President of N&B Management. Ms. Havell is the Manager of the Fixed  Income
Group of Neuberger&Berman, which she established in 1984. The Fixed Income Group
manages  fixed income accounts that had approximately $11.1 billion of assets as
of December  31,  1995.  Ms.  Havell has  had  overall  responsibility  for  the
activities of the Fixed Income Group since 1984.
    
   
   Josephine  P. Mahaney and Theresa A. Havell are primarily responsible for the
day-to-day management of AMT  Liquid Asset Investments. Ms.  Mahaney has been  a
Senior Portfolio Manager in the Fixed Income Group since 1984, an Assistant Vice
President  of  N&B Management  from 1986  to 1994  and a  Vice President  of N&B
Management since November 1994. Ms.  Mahaney has been primarily responsible  for
AMT Liquid Asset Investments since January 1993.
    
   N&B  Management serves as distributor in  connection with the offering of the
Liquid Asset Portfolio's shares. In connection with the sale of the  Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information and  to  make  only  such  statements  and  representations  as  are
contained in the Portfolio's Prospectus. The distributor is responsible only for
information  given and  statements and  representations made  in the Portfolio's
Prospectus and is not responsible for any information given or any statements or
representations made by  the Life  Companies or  by brokers  or salespersons  in
connection with Variable Contracts.
 
                                                                              15
<PAGE>
   
   Neuberger&Berman   acts  as  the  principal   broker  for  AMT  Liquid  Asset
Investments to the extent a broker is used in the purchase and sale of portfolio
securities and  in the  sale of  covered call  options, and  for those  services
receives brokerage commissions. In effecting securities transactions, AMT Liquid
Asset  Investments seeks to obtain  the best price and  execution of orders. For
more information, see the SAI.
    
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate the  possibility that the  Series will be  adversely affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.
 
          Expenses

   N&B  Management provides investment  management services to  AMT Liquid Asset
Investments that include, among other things, making and implementing investment
decisions and  providing  facilities  and personnel  necessary  to  operate  the
Series.  N&B  Management provides  administrative services  to the  Liquid Asset
Portfolio that  include  furnishing similar  facilities  and personnel  for  the
Portfolio.  With  the  Portfolio's  consent,  N&B  Management  is  authorized to
subcontract some of its responsibilities under its administration agreement with
the  Portfolio  to  third  parties.  For  such  administrative  and   investment
management services, N&B Management is paid the following fees:

   The  Liquid Asset Portfolio  bears all expenses of  its operations other than
those borne  by  N&B  Management  as  administrator  of  the  Portfolio  and  as
distributor  of its shares.  AMT Liquid Asset Investments  bears all expenses of
its operations other than those borne by N&B Management as investment manager of
the Series. These expenses  include, but are not  limited to, for the  Portfolio
and  the Series, legal and accounting fees and compensation for trustees who are
not affiliated with N&B Management; for  the Portfolio, transfer agent fees  and
the  cost of printing  and sending reports and  proxy materials to shareholders;
and for the Series,  custodial fees for securities.  Any expenses which are  not
directly attributable to a specific Series are allocated on the basis of the net
assets of the respective Series.

          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management has undertaken to limit the Liquid Asset Portfolio's expenses
by reimbursing the Portfolio for its  operating expenses and its pro rata  share
of  AMT Liquid Asset Investments  operating expenses, including the compensation
of N&B  Management,  but  excluding  taxes,  interest,  extraordinary  expenses,
brokerage  commissions and transaction costs, that  exceed 1% of the Portfolio's
average daily net asset value. This undertaking is subject to termination on  60
days' prior written notice to the Portfolio.
    
   The effect of any expense limitation by N&B Management is to reduce operating
expenses of the Portfolio and the Series and thereby increase total return.
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State  Street Bank and Trust Company ("State Street"), Boston, Massachusetts,
acts as transfer and dividend paying agent for the Liquid Asset Portfolio and in
so doing  performs  certain  bookkeeping,  data  processing  and  administrative
services.  All  correspondence  should be  sent  to  State Street  Bank  & Trust
Company, P.O. Box 1978, Boston, MA 02105. State Street provides similar services
to AMT Liquid Asset Investments as the Series' transfer agent. State Street also
acts as the custodian of the Series' and the Portfolios' assets.
    
 
                                                                              17
<PAGE>
DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   Shares of the Trust are issued and redeemed in connection with investments in
and  payments under the  Variable Contracts issued  through separate accounts of
the Life Companies which may or may not be affiliated with the Trust. Shares  of
one  Portfolio of the Trust are also offered directly to Qualified Plans. Shares
of the Trust are purchased and redeemed at net asset value.
   The Boards of  Trustees of the  Trust and Managers  Trust have undertaken  to
monitor  the Trust  and Managers Trust,  respectively, for the  existence of any
material irreconcilable conflict between the interests of the Variable  Contract
owners  of the Life  Companies and to  determine what action,  if any, should be
taken in the  event of a  conflict. The  Life Companies and  N&B Management  are
responsible for reporting any potential or existing conflicts to the Boards. Due
to  differences of tax  treatment and other  considerations, it is theoretically
possible that the interests of various Variable Contract owners participating in
the Trust and Managers Trust and  the interests of Qualified Plans investing  in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or  more Life  Company separate accounts  or Qualified Plans  might withdraw its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions will be  effected by  the separate accounts  to meet  obligations
under  the Variable Contracts and by the Qualified Plans. Contract owners do not
deal directly  with the  Trust  with respect  to  acquisition or  redemption  of
shares.  The trustees of the Trust may refuse to sell shares of any Portfolio to
any person, or suspend or terminate the  offering of shares of any Portfolio  if
such  action is required by law or by regulatory authorities having jurisdiction
or is, in the sole discretion of the trustees acting in good faith and in  light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The  Board of Trustees of  the Trust has adopted  a non-fee Distribution Plan
for each Portfolio of the Trust.
   The Distribution Plan recognizes that N&B  Management may use its assets  and
resources,  including its profits from administration  fees paid by a Portfolio,
to pay expenses associated with  the distribution of Portfolio shares.  However,
N&B  Management will  not receive  any separate fees  for such  expenses. To the
extent that any payments  made by a  Portfolio should be  deemed to be  indirect
financing  of any activity primarily intended to result in the sale of shares of
the Portfolio within the  context of Rule  12b-1 under the  1940 Act, then  such
payments shall be deemed to be authorized by the Distribution Plan.
   Under  the Distribution  Plan, the Portfolio  will require  N&B Management to
provide the Trust with quarterly reports  of the amounts expended in  connection
with  financing  any  activity  primarily  intended to  result  in  the  sale of
Portfolio shares,  and the  purpose for  which such  expenditure was  made.  The
Distribution  Plan may be terminated as to a particular Portfolio at any time by
a vote of a majority of the independent trustees of the Trust or by a vote of  a
majority   of  the  outstanding   voting  securities  of   that  Portfolio.  The
Distribution Plan does not require N&B  Management to perform any specific  type
or  level of distribution activities or to  incur any specific level of expenses
for activities  primarily  intended to  result  in the  sale  of shares  of  the
Portfolio.

DESCRIPTION OF INVESTMENTS
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Liquid  Asset  Investments may  make  the following  investments,  among others,
individually or in combination, although the Series may not necessarily buy  any
or all of the types of securities or use any or all of the investment techniques
that  are described. These  investments may be limited  by the requirements with
which the  Series  must comply  if  the Portfolio  is  to qualify  as  regulated
investment companies for tax purposes. The use of hedging or other techniques is
discretionary  and no representation is  made that the risk  of AMT Liquid Asset
Investments will be  reduced by the  techniques discussed in  this section.  For
additional  information  on  the following  investments  and on  other  types of
investments the Series may make, see the SAI.
    
 
    U.S. GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities  are
obligations  of the  U.S. Treasury backed  by the  full faith and  credit of the
United States. U.S.  Government Agency  securities are issued  or guaranteed  by
U.S.  Government agencies, instrumentalities, or other U.S. Government-sponsored
enterprises, such  as the  Government  National Mortgage  Association  ("GNMA"),
Federal  National  Mortgage  Association ("FNMA"),  Federal  Home  Loan Mortgage
Corporation ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee  Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may  be backed by the  full faith and credit of  the United States, the issuer's
ability to borrow from the U.S.  Treasury, subject to the Treasury's  discretion
in  certain cases,  or only  by the  credit of  the issuer.  U.S. Government and
Agency securities include certain mortgage-backed securities. The market  prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID  SECURITIES. The Series may  invest up to 10%  of its net assets in
securities that are illiquid, in that they cannot be expected to be sold  within
seven  days at  approximately the  price at  which they  are valued.  Due to the
absence of an  active trading market,  the Series may  experience difficulty  in
valuing  or  disposing of  illiquid  securities. N&B  Management  determines the
liquidity of  the  Series' securities,  under  supervision of  the  trustees  of
Managers Trust. Securities which are freely tradeable in their country of origin
or  in their principal market will not be considered illiquid securities even if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally outside the  U.S., including non-U.S.  governments, their  agencies,
and instrumentalities.
   Investments  in foreign securities could be affected by factors generally not
thought to be present in the U.S. Such factors include, but are not limited  to,
varying  custody, brokerage and settlement practices; difficulty in pricing some
foreign securities; less  public information about  issuers of securities;  less
governmental regulation and supervision over issuance and trading of securities;
the  unavailability of financial  information or the  difficulty of interpreting
financial  information  prepared  under   foreign  accounting  standards;   less
liquidity  and more volatility in foreign securities markets; the possibility of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or  diplomatic developments;  limitations on  the movement  of funds  or
other assets of the Series between different countries; difficulties in invoking
legal  process abroad and enforcing  contractual obligations; and the difficulty
of assessing  economic  trends  in  foreign  countries.  Investment  in  foreign
securities  also  involves higher  brokerage  and custodian  expenses  than does
investment in domestic securities.
   
   In addition, investing in securities of foreign companies and governments may
involve other  risks  which are  not  ordinarily associated  with  investing  in
domestic  securities. These risks include changes in currency exchange rates and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions applicable to such investments or
    
 
                                                                              19
<PAGE>
   
devaluations  of foreign currencies. A decline in the exchange rate would reduce
the value of certain portfolio securities irrespective of the performance of the
underlying investment. In  addition, the  Series may incur  costs in  connection
with  conversion between various currencies.  Investments in depositary receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and changes in  rates of exchange  with the U.S.  dollar because the  underlying
security  is usually denominated in foreign currency. All of the foregoing risks
may be intensified in emerging industrialized and less developed countries.
    
 
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements and lend securities  from its portfolio.  In a repurchase  agreement,
the  Series buys a security from a  Federal Reserve member bank, or a securities
dealer and  simultaneously agrees  to  sell it  back at  a  higher price,  at  a
specified  date, usually less than a  week later. The underlying securities must
fall within the Series' investment policies and limitations (but not limitations
as to  maturity).  The Series  also  may  lend portfolio  securities  to  banks,
brokerage  firms, or  institutional investors to  earn income.  Costs, delays or
losses could  result if  the selling  party  to a  repurchase agreement  or  the
borrower  of portfolio  securities becomes  bankrupt or  otherwise defaults. N&B
Management monitors the creditworthiness of sellers and borrowers.
 
    REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the Series
sells securities to a bank or securities  dealer and at the same time agrees  to
repurchase  the same  securities at a  later date  at a fixed  price. During the
period before  the repurchase,  the Series  continues to  receive principal  and
interest payments on the securities. The Series is compensated by the difference
between  the current sales price  and the forward price  for the future purchase
(often referred to as the "drop"), as well as by the interest earned on the cash
proceeds of the  initial sale.  Reverse repurchase agreements  may increase  the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B  Management monitors the  creditworthiness of parties  to reverse repurchase
agreements.
 
    MORTGAGE-BACKED SECURITIES. Mortgage-backed  securities represent  interests
in,  or are  secured by  and payable  from, pools  of mortgage  loans, including
collateralized mortgage  obligations. These  securities may  be U.S.  Government
mortgage-backed  securities, which are issued or guaranteed by a U.S. Government
agency or instrumentality (though not necessarily  backed by the full faith  and
credit  of the United States), such as  GNMA, FNMA and FHLMC certificates. Other
mortgage-backed securities are issued by private issuers, generally  originators
of  and investors  in mortgage  loans, including  savings associations, mortgage
bankers, commercial  banks, investment  bankers, and  special purpose  entities.
These  private mortgage-backed  securities may  be supported  by U.S. Government
mortgage-backed securities or  some form of  non-government credit  enhancement.
Mortgage-backed  securities may have either  fixed or adjustable interest rates.
Tax or regulatory changes may  adversely affect the mortgage securities  market.
In  addition, changes in  the market's perception  of the issuer  may affect the
value of  mortgage-backed  securities. The  rate  of return  on  mortgage-backed
securities  may be affected by prepayments of principal on the underlying loans,
which generally increase as interest rates  decline; as a result, when  interest
rates  decline,  holders  of  these  securities  normally  do  not  benefit from
appreciation in market value to the same extent as holders of other non-callable
debt securities. N&B Management  determines the effective  life and duration  of
mortgage-backed  securities  based  on  industry  practice  and  current  market
conditions. If N&B Management's determination is  not borne out in practice,  it
could  positively  or negatively  affect  the value  of  the Series  when market
interest rates change.  Increasing market  interest rates  generally extend  the
effective maturities of mortgage-backed securities.
 
    ASSET-BACKED  SECURITIES. Asset-backed securities represent interests in, or
are secured  by  and payable  from  pools of  assets,  such as  consumer  loans,
CARS-SM-  ("Certificates  for Automobile  Receivables"), credit  card receivable
securities, and installment  loan contracts.  Although these  securities may  be
supported by letters of credit or other
 
20
<PAGE>
credit  enhancements, payment of interest  and principal ultimately depends upon
individuals paying the underlying loans.  The risk that recovery on  repossessed
collateral   might  be  unavailable,  or   inadequate  to  support  payments  on
asset-backed  securities  is  greater  than  in  the  case  of   mortgage-backed
securities.
   
    SHORT SELLING. The Series may make short sales against-the box. A short sale
is  "against-the-box" when, at all times during  which a short position is open,
the Series owns an equal amount of such securities, or owns securities giving it
the right, without payment of future consideration, to obtain an equal amount of
securities sold short.
    
 
    VARIABLE AND FLOATING RATE SECURITIES. Variable and floating rate securities
have interest  rate adjustment  formulas  that help  to stabilize  their  market
value. Many of these instruments carry a demand feature which permits the Series
to sell them during a determined time period at par value plus accrued interest.
The  demand feature is often backed by a  credit instrument, such as a letter of
credit, or by a creditworthy insurer. The Series may rely on such instrument  or
the  creditworthiness of the  insurer in purchasing a  variable or floating rate
security. For purposes of determining its dollar-weighted average maturity,  the
Series   calculates  the  remaining  maturity  of  variable  and  floating  rate
instruments as provided in Rule 2a-7 under the 1940 Act.
 
    ZERO  COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay   interest
currently;  instead, they are sold  at a discount from  their face value and are
redeemed at face value when  they mature. Because zero  coupon bonds do not  pay
current income, their prices can be very volatile when interest rates change. In
calculating  its daily  income, the Series  accrues a portion  of the difference
between a zero coupon bond's purchase price and its face value.
 
    RESTRICTED SECURITIES AND  RULE 144A  SECURITIES. The Series  may invest  in
restricted  securities and Rule 144A securities. Restricted securities cannot be
sold to the public without registration under the Securities Act of 1933  ("1933
Act").  Unless  registered  for  sale,  these securities  can  be  sold  only in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted securities are generally  considered illiquid. Rule 144A  securities,
although not registered, may be resold only to qualified institutional buyers in
accordance  with Rule 144A under the  1933 Act. Unregistered securities may also
be sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B  Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.
 
                                                                              21

USE OF JOINT STATEMENT OF ADDITIONAL INFORMATION
   Each  Portfolio and its  corresponding Series acknowledges  that it is solely
responsible for all information or lack of information about that Portfolio  and
Series in the SAI, and no other Portfolio or Series is responsible therefor. The
trustees  of the  Trust and  of Managers  Trust have  considered this  factor in
approving each Portfolio's and Series' use of a single combined SAI.

ADVISERS MANAGEMENT TRUST
 
          Partners Portfolio
 
- --------------------------------------------------------------------------------
 
   Neuberger&Berman  ADVISERS MANAGEMENT TRUST (the "Trust") is intended to meet
differing investment objectives  and currently  is comprised  of seven  separate
Portfolios,  one  of  which is  offered  herein.  While each  portfolio  (each a
"Portfolio" and  collectively, "Portfolios")  issues its  own class  of  shares,
which  in some instances have rights separate  from other classes of shares, the
Trust is  one entity  with respect  to certain  important items  (e.g.,  certain
voting rights).
   Shares   of  the  Trust  are  offered  to  life  insurance  companies  ("Life
Companies") for  allocation  to  certain of  their  variable  separate  accounts
established  for the purpose of funding  variable annuity contracts and variable
life insurance policies ("Variable Contracts"). Shares of one of the  Portfolios
are  also offered directly to qualified pension and retirement plans ("Qualified
Plans").
   THIS PROSPECTUS  CONTAINS INFORMATION  PERTAINING TO  THE PARTNERS  PORTFOLIO
ONLY.
 
- --------------------------------------------------------------------------------
 
   
   EACH  PORTFOLIO INVESTS ALL OF ITS NET INVESTABLE ASSETS IN ITS CORRESPONDING
SERIES (EACH  A "SERIES")  OF  ADVISERS MANAGERS  TRUST ("MANAGERS  TRUST"),  AN
OPEN-END  MANAGEMENT INVESTMENT COMPANY. AMT  PARTNERS INVESTMENTS, THE PARTNERS
PORTFOLIO'S CORRESPONDING  SERIES,  IS MANAGED  BY  NEUBERGER&BERMAN  MANAGEMENT
INCORPORATED  ("N&B MANAGEMENT"). AMT PARTNERS INVESTMENTS INVESTS IN SECURITIES
IN ACCORDANCE WITH AN INVESTMENT OBJECTIVE, POLICIES, AND LIMITATIONS  IDENTICAL
TO  THOSE OF THE PARTNERS PORTFOLIO.  THE INVESTMENT PERFORMANCE OF THE PARTNERS
PORTFOLIO WILL  DIRECTLY  CORRESPOND  WITH THE  INVESTMENT  PERFORMANCE  OF  AMT
PARTNERS INVESTMENTS. THIS "MASTER/FEEDER FUND" STRUCTURE IS DIFFERENT FROM THAT
OF  MANY OTHER INVESTMENT COMPANIES WHICH  DIRECTLY ACQUIRE AND MANAGE THEIR OWN
PORTFOLIOS OF SECURITIES. FOR MORE INFORMATION ON THIS UNIQUE STRUCTURE THAT YOU
SHOULD   CONSIDER,    SEE   "SPECIAL    INFORMATION   REGARDING    ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS" ON PAGE 11.

SUMMARY
 
          The Portfolios and Series
 
- --------------------------------------------------------------------------------
 
   
   On May 1, 1995 the Trust was reorganized into a master/feeder structure. Each
Portfolio of the Trust invests in a corresponding Series of Managers Trust that,
in  turn,  invests in  securities in  accordance  with an  investment objective,
policies, and limitations  that are  identical to  those of  the Portfolio.  The
trustees  of  the Trust  believe that  this  "master/feeder fund"  structure may
benefit shareholders.  For  more  information  about  the  organization  of  the
Portfolios  and the Series, including certain features of the master/feeder fund
structure, see "Special Information Regarding Organization, Capitalization,  and
Other  Matters" on page 11. For more details about AMT Partners Investments, its
investments and their  risks, see "Investment  Program" on page  7, "Ratings  of
Securities"  on page 8, "Borrowings" on page 9, and "Description of Investments"
on page 21.
    
   
   Here is a  summary of important  features of the  Partners Portfolio and  AMT
Partners  Investments. Of course,  there can be no  assurance that the Portfolio
will meet its investment objective.

</TABLE>
 
          Risk Factors
 
- --------------------------------------------------------------------------------
 
   
   An investment in  any Portfolio  involves certain risks,  depending upon  the
types  of investments  made by  its corresponding  Series. Special  risk factors
apply to investments which  may be made by  AMT Partners Investments in  foreign
securities,  options,  zero  coupon  bonds,  and  debt  securities  rated  below
investment grade. AMT Partners Investments  invests in fixed income  securities,
the  value of which is  likely to decline in times  of rising interest rates and
rise in times of falling interest rates. In general, the longer the maturity  of
a  fixed  income security,  the more  pronounced is  the effect  of a  change in
interest rates on the value of the security.
    
   
   AMT Partners Investments may invest up to 15% of its net assets, measured  at
the  time of  investment, in  corporate debt  securities rated  below investment
grade or comparable unrated securities. Securities rated below investment  grade
as well as unrated securities are often considered to be speculative and usually
entail  greater  risk.  For  more  information  on  lower-rated  securities, see
"Ratings of Securities" in this Prospectus and "Fixed Income Securities" in  the
SAI.
    
 
          Management
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management,  with  the assistance  of  Neuberger&Berman  as sub-adviser,
selects investments for AMT Partners  Investments. N&B Management also  provides
administrative  services to AMT Partners  Investments and the Partners Portfolio
and acts as  distributor of  the shares of  the Portfolio.  See "Management  and
Administration" in this Prospectus.
    
 
                                                                               3
<PAGE>
          The Neuberger&Berman Investment Approach
 
- --------------------------------------------------------------------------------
 
   
   AMT  Partners  Investments  is managed  using  the  value-oriented investment
approach. A value-oriented  portfolio manager  buys stock that  are selling  for
less  than their perceived market value. These include stocks that are currently
under-researched or are temporarily out of favor on Wall Street.
    
   
   Portfolio managers identify  value stocks in  several ways. One  of the  most
common  identifiers is a low price-to-earnings  ratio -- that is, stocks selling
at multiples of earnings per share that are  lower than that of the market as  a
whole.  Other  criteria are  high  dividend yield,  a  strong balance  sheet and
financial position, a recent company restructuring with the potential to realize
hidden values, strong management, and low price-to-book value (net value of  the
company's assets).
    
   
   Neuberger&Berman  believes that,  over time, securities  that are undervalued
are more likely  to appreciate in  price and be  subject to less  risk of  price
decline than securities whose market prices have already reached their perceived
economic  value. This  approach also  contemplates selling  portfolio securities
when they are considered to have reached their potential.
    
   
   While this approach has resulted in  solid returns over the long term,  there
can  be no assurance that these results will be achieved in the future. For more
information, see "Performance Information" in this Prospectus.

  number of shares outstanding during each year.
    
   
2)The  per share amounts and ratios which are shown reflect income and expenses,
  including the  Portfolio's  proportionate  share of  the  Series'  income  and
  expenses.

5)Annualized.
    
   
6)The  Portfolio transferred all of its investment securities into its Series on
  April 28, 1995. After that date the Portfolio invested only in its Series  and
  that  Series, rather than  the Portfolio, engaged  in securities transactions.
  Therefore, after that date the Portfolio  had no portfolio turnover rate.  The
  portfolio  turnover rate for AMT Partners  Investments for the period from May
  1, 1995 to December 31, 1995 was 98%.
    
   
+Total return based on per share net asset value reflects the effects of changes
 in net asset value  on the performance  of the Portfolio  during each year  and
 assumes  dividends  and capital  gain distributions,  if any,  were reinvested.
 Results represent  past  performance  and  do  not  guarantee  future  results.
 Investment  returns and principal may fluctuate and shares when redeemed may be
 worth more or less than original cost. The total return information shown  does
 not  reflect  expenses  that  apply  to the  separate  account  or  the related
 insurance policies, and the inclusion of  these charges would reduce the  total
 return figures for all years shown.

INVESTMENT PROGRAM
    
   
   The  investment policies  and limitations of  the Partners  Portfolio and AMT
Partners Investments are identical. The  Partners Portfolio invests only in  AMT
Partners Investments. Therefore, the following shows you the kinds of securities
in  which AMT Partners Investments invests. For  an explanation of some types of
investments, see "Description of Investments" on page 21.
    
   Investment policies  and  limitations  of  the  Partners  Portfolio  and  AMT
Partners  Investments  are not  fundamental unless  otherwise specified  in this
Prospectus or  the SAI.  While a  non-fundamental policy  or limitation  may  be
changed  by the trustees of  the Trust or of  Managers Trust without shareholder
approval, the Partners  Portfolio intends to  notify shareholders before  making
any  material change to  such policies or  limitations. Fundamental policies and
limitations may not  be changed without  shareholder approval. There  can be  no
assurance  that AMT Partners Investments and the Partners Portfolio will achieve
their objectives.  The  Partners Portfolio,  by  itself, does  not  represent  a
comprehensive investment program.
   
   Additional  investment techniques,  features, and  limitations concerning AMT
Partners Investments' investment program are described in the SAI.
    
 
          AMT Partners Investments
 
- --------------------------------------------------------------------------------
 
   The investment  objective  of  AMT  Partners  Investments  and  the  Partners
Portfolio   is   to  seek   capital   growth.  This   investment   objective  is
non-fundamental. The Portfolio intends to notify shareholders 30 days in advance
of making any material change to its investment objective.
   AMT Partners Investments  invests primarily in  common stocks of  established
companies,  using  the  value-oriented  investment  approach.  The  Series seeks
capital growth  through an  investment  approach that  is designed  to  increase
capital  with reasonable risk. Its  investment program seeks securities believed
to be undervalued  based on  strong fundamentals such  as low  price-to-earnings
ratios, consistent cash flow, and support from asset values.
   
   Up  to 15% of the Series' net assets, measured at the time of investment, may
be invested in  corporate debt  securities rated  below investment  grade or  in
unrated  securities determined  to be  of comparable  quality by  N&B Management
("comparable unrated securities").  Securities rated below  investment grade  as
well as comparable unrated securities are often considered to be speculative and
usually entail greater risk. For more information on lower rated securities, see
"Ratings  of Securities"  in this Prospectus,  "Fixed Income  Securities" in the
SAI, and Appendix A of the SAI.
    
 
          Short-Term Trading; Portfolio Turnover
 
- --------------------------------------------------------------------------------
 
   Although AMT  Partners  Investments does  not  purchase securities  with  the
intention  of profiting from  short-term trading, the  Series may sell portfolio
securities prior  to maturity  when the  investment adviser  believes that  such
action is advisable.
   
   The  portfolio turnover  rates for  the Partners  Portfolio and  AMT Partners
Investments, and for the  predecessor of the Partners  Portfolio for the  period
prior  to  May 1,  1995,  are set  forth  under "Financial  Highlights"  in this
Prospectus. It is  anticipated that the  annual portfolio turnover  rate of  AMT
Partners Investments generally will exceed 100%.
    
   Turnover  rates in excess of 100% may result in higher costs (which are borne
directly by the Series) and a possible increase in short-term capital gains  (or
losses).
 
                                                                               7

that have received a rating from at least one nationally recognized  statistical
rating  organization ("NRSRO"), such as Standard  & Poor's Ratings Group ("S&P")
or Moody's Investors Service, Inc. ("Moody's"), in one of the two highest rating
categories (the highest  category in the  case of commercial  paper) or, if  not
rated  by any NRSRO,  such as U.S.  Government and Agency  securities, have been
determined by N&B Management to be of comparable quality.
 
   
    INVESTMENT GRADE  DEBT SECURITIES.  "Investment grade"  debt securities  are
those  receiving one of the  four highest ratings from  Moody's, S&P, or another
NRSRO or, if unrated by any NRSRO,  deemed comparable by N&B Management to  such
rated securities under guidelines established by the trustees of Managers Trust.
Moody's  deems securities  rated in  its fourth  highest category  (Baa) to have
speculative characteristics;  a  change in  economic  factors could  lead  to  a
weakened capacity of the issuer to repay.
    
   If  the quality  of securities  held by the  Series deteriorates  so that the
securities would no longer satisfy its  standards, the Series will engage in  an
orderly  disposition of  the downgraded  securities to  the extent  necessary to
ensure that the Series' holdings  of such securities will  not exceed 5% of  the
Series' net assets.
   
    LOWER-RATED  SECURITIES. Debt securities rated lower  than Baa by Moody's or
BBB by S&P and  debt securities determined  to be of  comparable quality by  N&B
Management   ("comparable  unrated  securities")  are  considered  to  be  below
investment grade.  AMT Partners  Investments may  invest up  to 15%  of its  net
assets,  measured  at the  time of  investment, in  debt securities  rated below
investment grade  or  comparable  unrated  securities.  Securities  rated  below
investment  grade  ("junk bonds")  are  deemed by  Moody's  and S&P  (or foreign
statistical rating organizations) to  be predominantly speculative with  respect
to  the issuer's capacity to pay interest and repay principal in accordance with
the terms of the obligations.
    
   
   Those  debt  securities  in  the  lowest  rating  categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or  developments regarding the individual issuer  are more likely to cause price
volatility and weaken  the capacity of  the issuers of  such securities to  make
principal  and  interest  payments  than  is  the  case  for  higher  grade debt
securities. An economic downturn affecting the issuer may result in an increased
incidence of  default  and a  decline  in  prices of  the  issuer's  lower-rated
securities.  In the case of lower-rated  securities structured as zero-coupon or
pay-in-kind securities, their market prices are affected to a greater extent  by
interest  rate changes, and  therefore tend to be  more volatile than securities
that pay interest periodically and in cash.
    
   
   The market for lower-rated securities may be thinner and less active than for
higher-rated securities. The  secondary market  in which  debt securities  rated
below investment grade and comparable unrated securities are traded is generally
less  liquid than the market for higher grade debt securities. Less liquidity in
the secondary  trading market  could adversely  affect the  price at  which  the
Series  could sell a debt security rated below investment grade, or a comparable
unrated security, and could  adversely affect the daily  net asset value of  the
Series'  shares. At times of less liquidity, it may be more difficult to value a
debt security rated below  investment grade, or  a comparable unrated  security,
because  such valuation may require more  research, and elements of judgment may
play a greater role in the  valuation because there is less reliable,  objective
data  available.  N&B Management  will invest  in such  securities only  when it
concludes that the  anticipated return to  the Portfolio on  such an  investment
warrants  exposure to  the additional  level of  risk. A  further description of
Moody's and S&P's ratings is included in Appendix A to the SAI.

   The value of  the fixed  income securities in  which the  Series may  invest,
measured  in the currency in which they are denominated, is likely to decline in
times of rising interest  rates. Conversely, when rates  fall, the value of  the
Series'  fixed income investments  may rise. The longer  the period remaining to
maturity, the more  pronounced is  the effect of  interest rate  changes on  the
value of a security.
    
 
          Borrowings
 
- --------------------------------------------------------------------------------
 
   AMT  Partners Investments  has a  fundamental policy  that it  may not borrow
money, except that it may (1) borrow money from banks for temporary or emergency
purposes and  not  for leveraging  or  investment  and (2)  enter  into  reverse
repurchase  agreements  for any  purpose,  so long  as  the aggregate  amount of
borrowings and reverse repurchase  agreements does not  exceed one-third of  the
Series'  total assets  (including the  amount borrowed)  less liabilities (other
than  borrowings).  The  Series   does  not  expect  to   borrow  money.  As   a
non-fundamental  policy, the Series may not purchase portfolio securities if its
outstanding borrowings, including  reverse repurchase agreements,  exceed 5%  of
its total assets.
   Currently,  the State of California imposes borrowing limitations on variable
insurance product funds.  To comply  with these  limitations, the  Series, as  a
matter of operating policy, has undertaken that it will not borrow more than 10%
of  its net  asset value  when borrowing  for any  general purpose  and will not
borrow more  than 25%  of its  net asset  value when  borrowing as  a  temporary
measure  to facilitate redemptions.  For these purposes, net  asset value is the
market value of all investments or assets owned less outstanding liabilities  at
the time that any new or additional borrowing is undertaken.
 
          Other Investments
 
- --------------------------------------------------------------------------------
 
   For  temporary defensive purposes, AMT Partners  Investments may invest up to
100% of  its total  assets in  cash and  cash equivalents,  U.S. Government  and
Agency  Securities, commercial paper and certain other money market instruments,
as well as repurchase agreements collateralized by the foregoing.
   To the extent that the Series is invested in temporary defensive instruments,
it will not be pursuing its investment objective.

PERFORMANCE INFORMATION
 
   
   Performance information for the Partners Portfolio may be presented from time
to time  in advertisements  and  sales literature.  The Portfolio's  "yield"  is
calculated by dividing the Portfolio's annualized net investment income during a
recent  30-day period by the Portfolio's net asset  value on the last day of the
period. The Portfolio's total return is  quoted for the one-year period and  for
the  life  of the  Portfolio through  the  most recent  calendar quarter  and is
determined  by  calculating  the  change  in  value  of  a  hypothetical  $1,000
investment in the Portfolio for each of those periods. Total return calculations
assume  reinvestment  of  all  Portfolio dividends  and  distributions  from net
investment income and net realized gains, respectively.
    
   All performance  information presented  for the  Portfolio is  based on  past
performance  and does not predict  future performance. Any Portfolio performance
information presented  will  also  include  or  be  accompanied  by  performance
information  for the Life Company separate accounts investing in the Trust which
will take  into  account  insurance-related  charges  and  expenses  under  such
insurance  policies and contracts. Further information regarding the Portfolio's
performance is presented in the Trust's annual report to shareholders, which  is
available without charge by calling 800-366-6264.
   Advertisements  concerning  the  Trust  may from  time  to  time  compare the
performance of the Portfolio to various indices. Advertisements may also contain
the performance  rankings  assigned the  Portfolio  or its  adviser  by  various
publications  and  statistical services.  Any such  comparisons or  rankings are
based  on  past  performance  and  the  statistical  computations  performed  by
publications  and  services,  and  are  not  necessarily  indications  of future
performance. Because the Portfolio is a managed investment vehicle investing  in
a  wide variety of  securities, the securities  owned by the  Portfolio will not
match those  making up  an index.  Please note  that indices  do not  take  into
account  any fees  and expenses of  investing in the  individual securities that
they track and that individuals cannot invest in any index.

SPECIAL INFORMATION REGARDING ORGANIZATION,
CAPITALIZATION, AND OTHER MATTERS
 
          The Portfolios
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio is a separate series  of the Trust, a Delaware business  trust
organized  pursuant  to a  Trust Instrument  dated  May 23,  1994. The  Trust is
registered under  the Investment  Company Act  of  1940 (the  "1940 Act")  as  a
diversified,  open-end management investment company, commonly known as a mutual
fund.  The  Trust  has  seven  separate  Portfolios.  The  predecessors  of  all
Portfolios were converted into the Portfolios on May 1, 1995, with the exception
of  one Portfolio which as of December 31, 1995 had not yet commenced investment
operations.  These  conversions  were  approved  by  the  shareholders  of   the
predecessors of the Portfolios in August 1994. Each Portfolio invests all of its
net  investable assets  in its  corresponding Series,  in each  case receiving a
beneficial interest in  that Series.  The trustees  of the  Trust may  establish
additional   portfolios  or   classes  of   shares,  without   the  approval  of
shareholders. The assets of  each Portfolio belong only  to that Portfolio,  and
the  liabilities of  each Portfolio  are borne solely  by that  Portfolio and no
other.
    
   
    DESCRIPTION OF SHARES. Each  Portfolio is authorized  to issue an  unlimited
number  of shares of beneficial interest (par value $0.001 per share). Shares of
each Portfolio represent  equal proportionate  interests in the  assets of  that
Portfolio only and have identical voting, dividend, redemption, liquidation, and
other rights. All shares issued are fully paid and non-assessable under Delaware
law,  and shareholders  have no  preemptive or other  right to  subscribe to any
additional shares.
    
 
    SHAREHOLDER MEETINGS. The trustees of the Trust do not intend to hold annual
meetings of  shareholders of  the  Portfolios. The  trustees will  call  special
meetings  of shareholders of a Portfolio only  if required under the 1940 Act or
in their discretion or upon the written request of holders of 10% or more of the
outstanding shares  of that  Portfolio  entitled to  vote. Pursuant  to  current
interpretations  of  the  1940  Act,  the  Life  Companies  will  solicit voting
instructions from Variable Contract owners with respect to any matters that  are
presented to a vote of shareholders of that Portfolio.
 
    CERTAIN  PROVISIONS  OF  THE  TRUST  INSTRUMENT.  Under  Delaware  law,  the
shareholders of a Portfolio will not be personally liable for the obligations of
any Portfolio; a  shareholder is  entitled to  the same  limitation of  personal
liability  extended to shareholders  of corporations. To  guard against the risk
that Delaware law  might not be  applied in other  states, the Trust  Instrument
requires  that every written  obligation of the  Trust or a  Portfolio contain a
statement that such obligation  may be enforced only  against the assets of  the
Trust  or Portfolio and  provides for indemnification out  of Trust or Portfolio
property of any  shareholder nevertheless  held personally liable  for Trust  or
Portfolio obligations, respectively.
 
          The Series
 
- --------------------------------------------------------------------------------
 
   Each  Series is a  separate series of  Managers Trust, a  New York common law
trust organized as of May 24, 1994. Managers Trust is registered under the  1940
Act as a diversified, open-end management investment company. Managers Trust has
seven  separate  Series.  On  May  1,  1995,  each  Portfolio  (other  than  the
International Portfolio which  as of  December 31,  1995 had  not yet  commenced
investment   operations)   invested   all   of   its   net   investable   assets
 
                                                                              11
<PAGE>
(cash, securities, and  receivables relating to  securities) in a  corresponding
Series  of Managers Trust,  receiving a beneficial interest  in that Series. The
assets of each Series belong  only to that Series,  and the liabilities of  each
Series are borne solely by that Series and no other.
   
    PORTFOLIOS'  INVESTMENT IN THE  SERIES. Each Portfolio  seeks to achieve its
investment objective  by investing  all  of its  net  investable assets  in  its
corresponding  Series  having  the  same  investment  objective,  policies,  and
limitations as the Portfolio. Accordingly, each Series directly acquires its own
securities and  its corresponding  Portfolio acquires  an indirect  interest  in
those  securities. Historically, N&B Management, administrator to the Portfolios
and investment  manager  of all  Series  has sponsored,  with  Neuberger&Berman,
traditionally  structured funds since  1950. However, it  has operated 12 master
funds and 20 feeder funds since August 1993 and now operates 21 master funds and
28 feeder funds.
    
   Each Portfolio's investment in its corresponding  Series is in the form of  a
non-transferable  beneficial  interest. Members  of the  general public  may not
purchase a direct interest in the Series. Currently, each Portfolio is the  sole
investor in its corresponding Series. It is possible that one or more Series, in
the  future,  may  permit  other  institutional  investors,  including  but  not
necessarily  limited  to  the  managed  separate  accounts  of  life   insurance
companies,  to invest in the Series. All  investors will invest in the Series on
the same terms  and conditions as  the Portfolios and  will pay a  proportionate
share  of the expenses  of the Series.  The Portfolios do  not sell their shares
directly to members of the general  public. Other investors in the Series  would
not  be required to sell their shares at the same offering price as a Portfolio,
could have a  different administration fee  and expenses than  a Portfolio,  and
might  charge  a sales  commission. Therefore,  Portfolio shareholders  may have
different returns than shareholders in  another entity that invests  exclusively
in the Series.
   A  Portfolio's investment in its corresponding  Series may be affected by the
actions of other large investors in the Series, if any. For example, if a  large
investor  in the  Series other  than a  Portfolio redeemed  its interest  in the
Series, the Series' remaining  investors (including the  Portfolio) might, as  a
result,  experience higher pro rata  operating expenses, thereby producing lower
returns.
   Each Portfolio  may withdraw  its entire  investment from  its  corresponding
Series  at any time,  if the trustees of  the Trust determine that  it is in the
best interests of the Portfolio and its shareholders to do so. A Portfolio might
withdraw, for example, if  there were other investors  in the Series with  power
to, and who did by a vote of all investors (including the Portfolio), change the
investment  objective, policies,  or limitations of  the Series in  a manner not
acceptable to  the  trustees  of the  Trust.  A  withdrawal could  result  in  a
distribution  in kind of securities  (as opposed to a  cash distribution) by the
Series. That  distribution  could result  in  a less  diversified  portfolio  of
investments  for the Portfolio  and could affect adversely  the liquidity of the
Portfolio's investment  portfolio.  If  a Portfolio  decided  to  convert  those
securities  to cash, it usually would  incur brokerage fees or other transaction
costs. If a  Portfolio withdrew  its investment  from the  Series, the  trustees
would  consider what action might  be taken, including the  investment of all of
the Portfolio's net investable assets in another pooled investment entity having
substantially the same investment objective as the Portfolio or the retention by
the Portfolio of its own investment  manager to manage its assets in  accordance
with  its investment objective, policies, and  limitations. The inability of the
Portfolio to find  a suitable  replacement could  have a  significant impact  on
shareholders.
 
    INVESTOR MEETINGS AND VOTING. Each Series normally will not hold meetings of
investors  except as required by the 1940  Act. Each investor in the Series will
be entitled to  vote in proportion  to its relative  beneficial interest in  the
Series. On most issues subjected to a vote of investors, as required by the 1940
Act  and  other  applicable  law,  a Portfolio  will  solicit  proxies  from its
shareholders and will vote its interest in the Series in proportion to the votes
cast by the
 
12
<PAGE>
Portfolio's shareholders. Pursuant to current  interpretations of the 1940  Act,
the  Life Companies  who are shareholders  of the Portfolio  will solicit voting
instructions from contract owners with respect to any matters that are presented
to a vote of Portfolio shareholders. If there are other investors in the Series,
there can be no assurance that any  issue that receives a majority of the  votes
cast  by Portfolio  shareholders will  receive a majority  of votes  cast by all
Series investors; indeed,  if other investors  hold a majority  interest in  the
Series, they could have voting control of the Series.
 
    CERTAIN PROVISIONS. Each investor in the Series, including a Portfolio, will
be  liable  for all  obligations of  the Series,  but not  of the  other Series.
However, the  risk of  an investor  in the  Series incurring  financial loss  on
account  of such liability would be limited to circumstances in which the Series
had inadequate  insurance and  was unable  to meet  its obligations  out of  its
assets. Upon liquidation of the Series, investors would be entitled to share pro
rata in the net assets of the Series available for distribution to investors.
 
                                                                              13
<PAGE>
SHARE PRICES AND NET ASSET VALUE
   Each Portfolio's shares are bought or sold at a price that is the Portfolio's
net  asset  value  ("NAV")  per  share. The  NAVs  for  each  Portfolio  and its
corresponding Series are calculated by subtracting liabilities from total assets
(in the case of the Series, the market value of the securities the Series  holds
plus  cash and other assets; in the case of a Portfolio, its percentage interest
in its  corresponding Series,  multiplied by  the Series'  NAV, plus  any  other
assets). Each Portfolio's per share NAV is calculated by dividing its NAV by the
number  of Portfolio shares  outstanding and rounding the  result to the nearest
full cent.
   The Partners Portfolio and AMT  Partners Investments calculate their NAVs  as
of the close of regular trading on The New York Stock Exchange ("NYSE"), usually
4 p.m. Eastern time.
   
   AMT  Partners Investments  values its  equity securities  (including options)
listed on the NYSE,  the American Stock Exchange,  other national exchanges,  or
the  NASDAQ market, and other securities for which market quotations are readily
available, at the latest sale price on the day NAV is calculated. If there is no
sale of such a security on that day, that security is valued at the mean between
its closing bid  and asked  prices. AMT  Partners Investments  values all  other
securities  and assets,  including restricted securities,  by a  method that the
trustees of Managers Trust believe accurately reflects fair value.

<PAGE>
DIVIDENDS, OTHER DISTRIBUTIONS AND TAX STATUS
 
          Dividends and Other Distributions
 
- --------------------------------------------------------------------------------
 
   
   The Partners Portfolio annually distributes substantially all of its share of
AMT  Partners  Investments'  net  investment  income  (net  of  the  Portfolio's
expenses),  net  realized capital  gains, and  net  realized gains  from foreign
currency transactions, if any, normally in February.
    
   The Partners Portfolio offers its shares  solely to separate accounts of  the
Life  Companies. All  dividends and other  distributions are  distributed to the
separate accounts and will be automatically invested in Trust shares.  Dividends
and  other  distributions made  by the  Portfolio to  the separate  accounts are
taxable, if at all, to the extent described in the prospectuses for the Variable
Contracts.
 
          Tax Status
 
- --------------------------------------------------------------------------------
 
   
   Each Portfolio  is  treated as  a  separate  entity for  Federal  income  tax
purposes  and  intends  to  qualify  annually  for  treatment  as  a  "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986,  as
amended ("Code"), so that it will be relieved of Federal income tax on that part
of its investment company taxable income (generally consisting of net investment
income,  net short-term capital gain and net gains from certain foreign currency
transactions) and net  capital gain (the  excess of net  long-term capital  gain
over  net short-term capital loss) that is distributed to its shareholders. Each
Portfolio intends  to  distribute  all  of  its net  income  and  gains  to  its
shareholders each year.
    
   
   The Trust and Managers Trust have received a ruling from the Internal Revenue
Service  that  each  Portfolio, as  an  investor  in a  corresponding  Series of
Managers Trust,  will be  deemed to  own a  proportionate share  of the  Series'
assets and income for purposes of determining whether the Portfolio qualifies as
a regulated investment company. That ruling also concluded that each such Series
will  be treated as a  separate partnership for Federal  income tax purposes and
will not be a "publicly traded partnership," with the result that none of  those
Series  will  be subject  to  Federal income  tax  (and, instead,  each investor
therein will take into account in  determining its Federal income tax  liability
its share of the Series' income, gains, losses, deductions, and credits).
    
   The  foregoing is only a summary of  some of the important Federal income tax
considerations generally affecting  the Portfolios and  their shareholders;  see
the  SAI for a  more detailed discussion. Prospective  shareholders are urged to
consult their tax advisers.
 
                                                                              15
<PAGE>
SPECIAL CONSIDERATIONS
   
   The Portfolios serve  as the  underlying investments  for Variable  Contracts
issued  through separate accounts of the Life  Companies which may or may not be
affiliated.  See  "Distribution  and  Redemption   of  Trust  Shares"  in   this
Prospectus.
    
   
   Section  817(h) of the Code imposes  certain diversification standards on the
underlying assets of segregated asset accounts  that fund contracts such as  the
Variable Contracts (that is, the assets of the Series), which are in addition to
the  diversification requirements imposed on the  Portfolios by the 1940 Act and
Subchapter M. Failure to satisfy those  standards would result in imposition  of
Federal  income tax on a Variable Contract owner with respect to the increase in
the value of the Variable Contract. Section 817(h)(2) provides that a segregated
asset account that funds contracts such as the Variable Contracts is treated  as
meeting  the  diversification standards  if, as  of the  close of  each calendar
quarter, the assets in the account  meet the diversification requirements for  a
regulated  investment company and  no more than  55% of those  assets consist of
cash, cash items, U.S. Government  securities and securities of other  regulated
investment companies.
    
   The  Treasury Regulations amplify the  diversification standards set forth in
Section 817(h)  and provide  an alternative  to the  provision described  above.
Under  the  regulations,  an  investment  portfolio  will  be  deemed adequately
diversified if (i)  no more than  55% of the  value of the  total assets of  the
portfolio  is represented by any  one investment; (ii) no  more than 70% of such
value is represented  by any two  investments; (iii)  no more than  80% of  such
value is represented by any three investments; and (iv) no more than 90% of such
value  is represented by any four investments. For purposes of these Regulations
all securities of the same issuer are  treated as a single investment, but  each
United  States  government  agency  or instrumentality  shall  be  treated  as a
separate issuer.
   
   Each Series  will be  managed  with the  intention  of complying  with  these
diversification requirements. It is possible that, in order to comply with these
requirements, less desirable investment decisions may be made which would affect
the investment performance of a Portfolio.
    
   
   Section  817  of the  Code  and the  Treasury  Regulations thereunder  do not
currently  address  variable  contract  diversification  in  the  context  of  a
master/feeder  fund structure. As described under  "Tax Status" above, the Trust
and Managers Trust  have received  a ruling  from the  Internal Revenue  Service
concluding  that the "look-through" rule of  Section 817, which would permit the
segregated asset  accounts to  look  through to  the  underlying assets  of  the
Series, will be available for the variable contract diversification test.
    
   Currently,  the State  of California imposes  diversification requirements on
variable insurance products funds investing in non-U.S. securities. Under  these
requirements, a fund investing at least 80% of its assets in non-U.S. securities
must  be invested in at least five countries; less than 80% but at least 60%, in
at least four  countries; less  than 60%  but at least  40%, in  at least  three
countries; and less than 40% but at least 20%, in at least two countries, except
that  up to  35% of  a fund's assets  may be  invested in  securities of issuers
located in any of the following countries: Australia, Canada, France, Japan, the
United Kingdom or Germany.  The Trust and Managers  Trust intend to comply  with
the California diversification requirements, to the extent applicable.

MANAGEMENT AND ADMINISTRATION
 
          Trustees and Officers
 
- --------------------------------------------------------------------------------
 
   The  trustees  of the  Trust  and the  trustees  of Managers  Trust,  who are
currently the same individuals, have  overall responsibility for the  operations
of  each  Portfolio  and each  Series,  respectively. The  SAI  contains general
background information  about each  trustee  and officer  of  the Trust  and  of
Managers Trust. The officers of the Trust and of Managers Trust who are officers
and/or  directors of  N&B Management  and/or partners  of Neuberger&Berman serve
without compensation from  the Portfolios  or the  Series. The  trustees of  the
Trust  and of Managers Trust, including a majority of those trustees who are not
"interested persons" (as defined in the 1940 Act) of any Portfolio, have adopted
written procedures reasonably  appropriate to deal  with potential conflicts  of
interest,  including, if  necessary, creating  a separate  board of  trustees of
Managers Trust.
 
          Investment Manager, Administrator, Sub-Adviser and Distributor
 
- --------------------------------------------------------------------------------
 
   
   N&B Management serves as the investment manager of AMT Partners  Investments,
as  administrator of the Partners Portfolio, and as distributor of the shares of
the  Partners  Portfolio.  N&B  Management   and  its  predecessor  firms   have
specialized in the management of no-load mutual funds since 1950. In addition to
serving  the  Series  of  Managers Trust,  N&B  Management  currently  serves as
investment   manager   or   investment   adviser   of   other   mutual    funds.
Neuberger&Berman,  which acts  as sub-adviser  for the  Series and  other mutual
funds managed by  N&B Management,  also serves  as investment  adviser of  three
other   investment  companies.   These  funds   had  aggregate   net  assets  of
approximately $11.9 billion as of December 31, 1995.
    
   
   As sub-adviser,  Neuberger&Berman furnishes  N&B Management  with  investment
recommendations  and  research information  without  added cost  to  the Series.
Neuberger&Berman is a member firm of the NYSE and other principal exchanges  and
acts  as the  Series' principal  broker in  the purchase  and sale  of portfolio
securities and  the  sale of  covered  call options.  Neuberger&Berman  and  its
affiliates,  including  N&B  Management,  manage  securities  accounts  that had
approximately $38.7 billion of assets as of December 31, 1995. All of the voting
stock of N&B  Management is  owned by individuals  who are  general partners  of
Neuberger&Berman.
    
   
   Michael  M. Kassen and Robert I.  Gendelman are primarily responsible for the
day-to-day management  of  AMT  Partners  Investments.  Mr.  Kassen  is  a  Vice
President  of N&B  Management and  a general  partner of  Neuberger& Berman. Mr.
Kassen was an employee of  N&B Management from 1990 to  December 1992. He was  a
portfolio  manager of  several large mutual  funds managed  by another prominent
investment adviser from  1981 to  1988 and was  general partner  of two  private
investment partnerships from 1988 to 1990. He has had primary responsibility for
AMT  Partners Investments since March 1994.  Mr. Gendelman is a senior portfolio
manager for Neuberger&Berman and an  Assistant Vice President of N&B  Management
since 1994. He has had primary responsibility for AMT Partners Investments since
October  1994. He was a  portfolio manager for another  mutual fund manager from
1992 to 1993 and was managing partner of an investment partnership from 1988  to
1992.
    
   
   N&B  Management serves as distributor in  connection with the offering of the
Partners Portfolio's  shares. In  connection with  the sale  of the  Portfolio's
shares,  the  Portfolio  has  authorized  the  distributor  to  give  only  such
information and  to  make  only  such  statements  and  representations  as  are
contained in the Portfolio's Prospectus. The

representations made in the  Portfolio's Prospectus and  is not responsible  for
any  information given  or any  statements or  representations made  by the Life
Companies or by brokers or salespersons in connection with Variable Contracts.
    
   Neuberger&Berman acts as the principal broker for the Series in the  purchase
and  sale of portfolio securities  and in the sale  of covered call options, and
for those  services  receives  brokerage commissions.  In  effecting  securities
transactions,  AMT  Partners  Investments seeks  to  obtain the  best  price and
execution of orders. For more information, see the SAI.
   The partners and employees of Neuberger&Berman and officers and employees  of
N&B Management, together with their families, have invested over $100 million of
their own money in Neuberger&Berman Funds.
   To  mitigate the  possibility that the  Series will be  adversely affected by
personal trading of employees,  the Trust, Managers  Trust, N&B Management,  and
Neuberger&Berman  have  adopted  policies that  regulate  securities  trading in
personal accounts of the  portfolio managers and others  who normally come  into
possession  of information on portfolio  transactions. These policies comply, in
all material  respects,  with  the recommendations  of  the  Investment  Company
Institute.

          Expense Limitation
    
 
- --------------------------------------------------------------------------------
 
   
   N&B  Management has undertaken to limit  the Partners Portfolio's expenses by
reimbursing the Portfolio for its operating  expenses and its pro rata share  of
AMT  Partners Investments' operating expenses, excluding the compensation of N&B
Management, taxes, interest, extraordinary  expenses, brokerage commissions  and
transaction  costs, that  exceed 1% of  the Portfolio's average  daily net asset
value. This undertaking  is subject  to termination  on 60  days' prior  written
notice to the Portfolio.
    
   
   The effect of any expense limitation by N&B Management is to reduce operating
expenses  of the  Partners Portfolio  and AMT  Partners Investments  and thereby
increase total return.
    
 
          Transfer and Dividend Paying Agent
 
- --------------------------------------------------------------------------------
 
   
   State Street Bank and Trust Company ("State Street"), Boston,  Massachusetts,
acts  as transfer and dividend paying agent for the Partners Portfolio and in so
doing performs certain bookkeeping, data processing and administrative services.
All correspondence should be sent to State Street Bank & Trust Company, P.O. Box
1978, Boston, MA 02105. State Street  provides similar services to AMT  Partners
Investments  as  the  Series' transfer  agent.  State  Street also  acts  as the
custodian of the Series' and the Portfolios' assets.

DISTRIBUTION AND REDEMPTION OF TRUST SHARES
 
          Distribution and Redemption of Trust Shares
 
- --------------------------------------------------------------------------------
 
   
   Shares of the Trust are issued and redeemed in connection with investments in
and payments under the  Variable Contracts issued  through separate accounts  of
the  Life Companies which may or may not be affiliated with the Trust. Shares of
one Portfolio of the Trust are also offered directly to Qualified Plans.  Shares
of the Trust are purchased and redeemed at net asset value.
    
   The  Boards of Trustees  of the Trust  and Managers Trust  have undertaken to
monitor the Trust  and Managers Trust,  respectively, for the  existence of  any
material  irreconcilable conflict between the interests of the Variable Contract
owners of the Life  Companies and to  determine what action,  if any, should  be
taken  in the  event of a  conflict. The  Life Companies and  N&B Management are
responsible for reporting any potential or existing conflicts to the Boards. Due
to differences of tax  treatment and other  considerations, it is  theoretically
possible that the interests of various Variable Contract owners participating in
the  Trust and Managers Trust and the  interests of Qualified Plans investing in
the Trust and Managers Trust may conflict. If such a conflict were to occur, one
or more Life  Company separate accounts  or Qualified Plans  might withdraw  its
investment in the Trust. This might force the Trust to sell portfolio securities
at disadvantageous prices.
   Redemptions  will be  effected by the  separate accounts  to meet obligations
under the Variable Contracts and by the Qualified Plans. Contract owners do  not
deal  directly  with the  Trust  with respect  to  acquisition or  redemption of
shares. The trustees of the Trust may refuse to sell shares of any Portfolio  to
any  person, or suspend or terminate the  offering of shares of any Portfolio if
such action is required by law or by regulatory authorities having  jurisdiction
or  is, in the sole discretion of the trustees acting in good faith and in light
of their fiduciary duties under federal and any applicable state laws, necessary
in the best interests of the shareholders of such Portfolio.
 
          Distribution Plan
 
- --------------------------------------------------------------------------------
 
   The Board of Trustees  of the Trust has  adopted a non-fee Distribution  Plan
for each Portfolio of the Trust.
   The  Distribution Plan recognizes that N&B  Management may use its assets and
resources, including its profits from  administration fees paid by a  Portfolio,
to  pay expenses associated with the  distribution of Portfolio shares. However,
N&B Management will  not receive  any separate fees  for such  expenses. To  the
extent  that any payments  made by a  Portfolio should be  deemed to be indirect
financing of any activity primarily intended to result in the sale of shares  of
the  Portfolio within the  context of Rule  12b-1 under the  1940 Act, then such
payments shall be deemed to be authorized by the Distribution Plan.
   Under the Distribution  Plan, the  Portfolio will require  N&B Management  to
provide  the Trust with quarterly reports  of the amounts expended in connection
with financing  any  activity  primarily  intended to  result  in  the  sale  of
Portfolio  shares,  and the  purpose for  which such  expenditure was  made. The
Distribution Plan may be terminated as to a particular Portfolio at any time  by
a  vote of a majority of the independent trustees of the Trust or by a vote of a
majority  of  the   outstanding  voting  securities   of  that  Portfolio.   The
Distribution  Plan does not require N&B  Management to perform any specific type
or level of distribution activities or  to incur any specific level of  expenses
for  activities  primarily intended  to  result in  the  sale of  shares  of the
Portfolio.

DESCRIPTION OF INVESTMENTS
   
   In addition to the securities referred to in "Investment Program" herein, AMT
Partners Investments, as  indicated below, may  make the following  investments,
among  others,  individually  or in  combination,  although the  Series  may not
necessarily buy any or all of the types  of securities or use any or all of  the
investment  techniques that are  described. These investments  may be limited by
the requirements  with which  the Series  must  comply if  the Portfolio  is  to
qualify  as regulated investment companies for  tax purposes. The use of hedging
or other techniques is discretionary and no representation is made that the risk
of AMT Partners Investments will be reduced by the techniques discussed in  this
section.  For additional information  on the following  investments and on other
types of investments the Series may make, see the SAI.
    
 
    U.S. GOVERNMENT  AND  AGENCY  SECURITIES.  U.S.  Government  securities  are
obligations  of the  U.S.Treasury backed  by the  full faith  and credit  of the
United States. U.S.  Government Agency  securities are issued  or guaranteed  by
U.S.  Government agencies, instrumentalities, or other U.S. Government-sponsored
enterprises, such  as the  Government  National Mortgage  Association  ("GNMA"),
Federal  National  Mortgage  Association ("FNMA"),  Federal  Home  Loan Mortgage
Corporation ("FHLMC"),  Student  Loan Marketing  Association,  Tennessee  Valley
Authority, and various federally chartered or sponsored banks. Agency securities
may  be backed by the  full faith and credit of  the United States, the issuer's
ability to borrow from the U.S.  Treasury, subject to the Treasury's  discretion
in  certain cases,  or only  by the  credit of  the issuer.  U.S. Government and
Agency securities include certain mortgage-backed securities. The market  prices
of U.S. Government securities are not guaranteed by the government and generally
fluctuate with changing interest rates.
 
    ILLIQUID  SECURITIES. The Series may  invest up to 10%  of its net assets in
securities that are illiquid, in that they cannot be expected to be sold  within
seven  days at  approximately the  price at  which they  are valued.  Due to the
absence of an  active trading market,  the Series may  experience difficulty  in
valuing  or  disposing of  illiquid  securities. N&B  Management  determines the
liquidity of  the  Series' securities,  under  supervision of  the  trustees  of
Managers Trust. Securities which are freely tradeable in their country of origin
or  in their principal market will not be considered illiquid securities even if
they are not registered for sale in the U.S.
 
    FOREIGN SECURITIES. The Series may invest in U.S. dollar-denominated foreign
securities. Foreign securities are those of issuers organized and doing business
principally outside the  U.S., including non-U.S.  governments, their  agencies,
and  instrumentalities.  The  Series  may  also  invest  in  foreign  securities
denominated in or indexed to foreign  currencies, which may also be affected  by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective of the  performance of  the underlying  investment. N&B  Management
considers these factors in making investments for the Series.
   
   AMT  Partners Investments  may invest  up to  10% of  the value  of its total
assets, measured  at the  time of  investment, in  foreign securities  that  are
issued  by non-United  States entities. The  10% limitation does  not apply with
respect to foreign securities  that are denominated  in U.S. dollars,  including
ADRs.  Foreign securities (including those denominated in U.S. dollars and ADRs)
are affected by political or economic developments in foreign countries.
    
   Investments in foreign securities could be affected by factors generally  not
thought  to be present in the U.S. Such factors include, but are not limited to,
varying custody, brokerage and settlement practices; difficulty in pricing  some
foreign  securities; less public  information about issuers  of securities; less
governmental regulation and supervision over issuance and trading of securities;
the unavailability of  financial information or  the difficulty of  interpreting
financial   information  prepared  under   foreign  accounting  standards;  less
liquidity and more volatility in foreign securities markets; the possibility  of
expropriation; the imposition of foreign withholding and other taxes; political,
social, or
 
                                                                              21
<PAGE>
diplomatic developments; limitations on the movement of funds or other assets of
the  Series between different countries;  difficulties in invoking legal process
abroad and enforcing  contractual obligations; and  the difficulty of  assessing
economic  trends  in foreign  countries. Investment  in foreign  securities also
involves higher  brokerage  and  custodian  expenses  than  does  investment  in
domestic securities.
   In addition, investing in securities of foreign companies and governments may
involve  other  risks  which are  not  ordinarily associated  with  investing in
domestic securities. These risks include changes in currency exchange rates  and
currency  exchange  control  regulations  or  other  foreign  or  U.S.  laws  or
restrictions  applicable  to  such   investments  or  devaluations  of   foreign
currencies.  A decline in  the exchange rate  would reduce the  value of certain
portfolio  securities  irrespective  of   the  performance  of  the   underlying
investment.  In  addition,  the  Series  may  incur  costs  in  connection  with
conversion  between  various  currencies.  Investments  in  depositary  receipts
(whether or not denominated in U.S. dollars) may be subject to exchange controls
and  changes in rates  of exchange with  the U.S. dollar  because the underlying
security is usually denominated in foreign currency. All of the foregoing  risks
may be intensified in emerging industrialized and less developed countries.
 
    FOREIGN  CURRENCY TRANSACTIONS.  The Series  may enter  into forward foreign
currency exchange  contracts in  order  to protect  against adverse  changes  in
future  foreign currency exchange  rates, to facilitate  transactions in foreign
securities and to  repatriate dividend  or interest income  received in  foreign
currencies.  The Series may enter into  contracts to purchase foreign currencies
to protect against an anticipated rise in the U.S. dollar price of securities it
intends to purchase. The  Series may also enter  into contracts to sell  foreign
currencies  to  protect  against a  decline  in  value of  its  foreign currency
denominated portfolio  securities due  to  a decline  in  the value  of  foreign
currencies  against the  U.S. dollar. Contracts  to sell  foreign currency could
limit any potential gain which might be  realized by the Series if the value  of
the hedged currency increased.
   The  Series may also  enter into forward  foreign currency exchange contracts
for non-hedging  purposes  when  the investment  adviser  anticipates  that  the
foreign  currency  will  appreciate  or  depreciate  in  value,  but  securities
denominated in that currency do not present attractive investment  opportunities
and  are not held in the Series. The  Series may also engage in cross-hedging by
using forward contracts  in one currency  to hedge against  fluctuations in  the
value  of  securities  denominated in  a  different currency  if  the investment
adviser believes  that  there  is  a pattern  of  correlation  between  the  two
currencies.
   If  the  Series enters  into  a forward  currency  exchange contract  to sell
foreign currency, it may  be required to  place cash or  high grade liquid  debt
securities  in  a segregated  account in  an amount  equal to  the value  of the
Series' total  assets committed  to the  consummation of  the forward  contract.
Although  these contracts  can protect the  Series from  adverse exchange rates,
they involve risk of  loss if N&B Management  fails to predict foreign  currency
values correctly.
 
    CALL  OPTIONS. The  Series may  try to reduce  the risk  of securities price
changes (hedge) or  generate income  by writing (selling)  covered call  options
against securities held in its portfolio having a market value not exceeding 10%
of its net assets and may purchase call options in related closing transactions.
The purchaser of a call option acquires the right to buy a portfolio security at
a  fixed  price during  a specified  period.  The maximum  price the  seller may
realize on the security during the option period is the fixed price. The  seller
continues  to bear the risk of a  decline in the security's price, although this
risk is reduced by the premium received for the option.
   
   The writing and purchasing of options is a highly specialized activity  which
involves  investment techniques and  risks different from  those associated with
ordinary portfolio  securities  transactions  including  transactional  expense,
price  volatility and a  high degree of  leverage. The writing  of options could
result in significant increases in the Series' turnover rate.
    
 
22
<PAGE>
   
   The primary risks in using call  options are (1) imperfect correlation or  no
correlation between changes in market value of the securities held by the Series
and  the prices of the  options; (2) possible lack  of a liquid secondary market
for the options and the resulting inability to close out an option when desired;
(3) the fact  that the skills  needed to  use options are  different from  those
needed  to select  the Series'  securities; (4) the  fact that,  although use of
these instruments for hedging  purposes can reduce the  risk of loss, they  also
can  reduce the opportunity  for gain, or  even result in  losses, by offsetting
favorable price movements in hedged investments; and (5) the possible  inability
of  the Series to purchase or sell a  security at a time that would otherwise be
favorable for  it to  do so,  or the  possible need  for the  Series to  sell  a
security  at a disadvantageous time,  due to its need  to maintain "cover" or to
segregate securities in connection  with its use  of these instruments.  Options
are considered derivatives.
    
   
    FORWARD  COMMITMENTS AND WHEN-ISSUED SECURITIES. In a when-issued or forward
commitment transaction, the Series  commits to purchase  securities in order  to
secure  an advantageous price and  yield at the time  of the commitment and pays
for the securities when  they are delivered at  a future date (generally  within
three months). If the seller fails to complete the sale, the Series may lose the
opportunity  to obtain  a favorable price  and yield.  When-issued securities or
securities subject to  a forward  commitment may  decline or  increase in  value
during  the period from  the Series' investment commitment  to the settlement of
the purchase which may magnify fluctuation in the Series' NAV.
    
 
    REPURCHASE AGREEMENTS/SECURITIES LOANS. The Series may enter into repurchase
agreements and lend securities  from its portfolio.  In a repurchase  agreement,
the  Series buys a security from a  Federal Reserve member bank, or a securities
dealer and  simultaneously agrees  to  sell it  back at  a  higher price,  at  a
specified  date, usually less than a  week later. The underlying securities must
fall within the Series' investment policies and limitations (but not limitations
as to maturity or  duration). The Series also  may lend portfolio securities  to
banks, brokerage firms, or institutional investors to earn income. Costs, delays
or  losses could result  if the selling  party to a  repurchase agreement or the
borrower of portfolio  securities becomes  bankrupt or  otherwise defaults.  N&B
Management monitors the creditworthiness of sellers and borrowers.
 
    REVERSE REPURCHASE AGREEMENTS. In a reverse repurchase agreement, the Series
sells  securities to a bank or securities dealer  and at the same time agrees to
repurchase the same  securities at a  later date  at a fixed  price. During  the
period  before the  repurchase, the  Series continues  to receive  principal and
interest payments on the securities. The Series is compensated by the difference
between the current sales  price and the forward  price for the future  purchase
(often referred to as the "drop"), as well as by the interest earned on the cash
proceeds  of the  initial sale. Reverse  repurchase agreements  may increase the
fluctuation in the market value of the Series' assets and are forms of leverage.
N&B Management monitors  the creditworthiness of  parties to reverse  repurchase
agreements.
 
    CONVERTIBLE  SECURITIES. The Series may  invest in convertible securities. A
convertible security  is a  bond,  debenture, note,  preferred stock,  or  other
security  that may  be converted  into or exchanged  for a  prescribed amount of
common stock of the  same or a  different issuer within  a particular period  of
time  at a  specified price  or formula.  Many convertible  securities are rated
below investment grade, or, are unrated.
 
    OTHER INVESTMENTS.  Although  the  Series ordinarily  invests  primarily  in
common stocks, when market conditions warrant the Series may invest in preferred
stocks,  securities  convertible into  or exchangeable  for common  stocks, U.S.
Government and Agency  Securities, investment  grade debt  securities, or  money
market instruments, or may retain assets in cash or cash equivalents.
 
    SHORT SELLING. The Series may attempt to limit exposure to a possible market
decline  in the value of portfolio  securities through short sales of securities
which the investment adviser believes possess volatility characteristics similar
to those being hedged and may use short sales in an attempt to realize gain.  To
effect such a transaction, the Series will
 
                                                                              23
<PAGE>
borrow  a security  from a  brokerage firm  to make  delivery to  the buyer. The
Series then is obligated  to replace the security  borrowed by purchasing it  at
the market price at the time of replacement. Until the security is replaced, the
Series is required to pay to the lender any accrued interest or dividend and may
be required to pay a premium.
   The  Series will realize a gain if the security declines in price between the
date of the short sale  and the date on which  the Series replaces the  borrowed
security.  The Series will incur  a loss if the  price of the security increases
between those dates. The amount of any gain will be decreased, and the amount of
any loss increased, by the amount of  any premium or interest the Series may  be
required  to pay in  connection with a  short sale. The  successful use of short
selling may be adversely affected by imperfect correlation between movements  in
the  price of  the security  sold short and  the securities  being hedged. Short
selling may defer recognition of gains or losses into another tax period.
   
   AMT Partners Investments may make  short sales against-the-box. A short  sale
is  "against-the-box" when, at all times during  which a short position is open,
the Series owns an equal amount of such securities, or own securities giving  it
the right, without payment of future consideration, to obtain an equal amount of
securities sold short.
    
 
    ZERO   COUPON  SECURITIES.  Zero  coupon  securities  do  not  pay  interest
currently; instead, they are sold  at a discount from  their face value and  are
redeemed  at face value when  they mature. Because zero  coupon bonds do not pay
current income, their prices can be very volatile when interest rates change. In
calculating its daily  income, the Series  accrues a portion  of the  difference
between a zero coupon bond's purchase price and its face value.
 
    RESTRICTED  SECURITIES AND  RULE 144A SECURITIES.  The Series  may invest in
restricted securities and Rule 144A securities. Restricted securities cannot  be
sold  to the public without registration under the Securities Act of 1933 ("1933
Act"). Unless  registered  for  sale,  these securities  can  be  sold  only  in
privately negotiated transactions or pursuant to an exemption from registration.
Restricted  securities are generally considered  illiquid. Rule 144A securities,
although not registered, may be resold only to qualified institutional buyers in
accordance with Rule 144A under the  1933 Act. Unregistered securities may  also
be  sold abroad  pursuant to  Regulation S under  the 1933  Act. N&B Management,
acting pursuant to guidelines established by the trustees of Managers Trust, may
determine that some restricted securities are liquid.

                             INVESTMENT INFORMATION
   
               Each  Portfolio  is a separate  series of the  Trust,  a Delaware
          business trust registered with the Securities and Exchange  Commission
          ("SEC") as a diversified, open-end management investment company. Each
          Portfolio  seeks its investment  objective by investing all of its net
          investable  assets in the  corresponding  Series of Advisers  Managers
          Trust ("Managers Trust"),  which has an investment objective identical
          to, and a name  similar to, that of the  Portfolio.  Each  Series,  in
          turn,  invests in accordance with an investment  objective,  policies,
          and  limitations  identical to those of its  corresponding  Portfolio.
          (The Trust and Managers Trust,  which also is a diversified,  open-end
          management  investment company,  are together referred to below as the
          "Trusts.")   All   Series   of   Managers   Trust   are   managed   by
          Neuberger&Berman Management Incorporated ("N&B Management").
    
               The  following  information  supplements  the  discussion  in the
          Prospectus of the investment objective,  policies,  and limitations of
          each  Portfolio and each Series.  Unless  otherwise  specified,  those
          investment  policies and  limitations  are not  fundamental.  However,
          although any investment  policy or limitation  that is not fundamental
          may be changed by the trustees of the Trust ("Portfolio  Trustees") or
          of Managers Trust ("Series  Trustees") without  shareholder  approval,
          each Portfolio intends to notify its shareholders  before implementing
          any material change in any non-fundamental  policy or limitation.  The
          fundamental  investment  policies and  limitations of a Portfolio or a
          Series may not be changed  without  the  approval of the lesser of (1)
          67% of the  total  units  of  beneficial  interest  ("shares")  of the
          Portfolio or Series represented at a meeting at which more than 50% of
          the  outstanding  Portfolio or Series shares are  represented or (2) a
          majority of the  outstanding  shares of the Portfolio or Series.  This
          vote is required by the  Investment  Company Act of 1940 ("1940  Act")
          and is referred to in this SAI as a "1940 Act majority vote." Whenever
          a  Portfolio  is  called  upon to vote on a change  in the  investment
          objective or a  fundamental  investment  policy or  limitation  of its
          corresponding  Series,  the  Portfolio  casts  its  votes  thereon  in
          proportion  to the  votes of its  shareholders  at a  meeting  thereof
          called for that purpose.

          Investment Policies and Limitations

               Each Portfolio has the following  fundamental  investment policy,
          to enable it to invest in its corresponding Series:

               Notwithstanding any other investment policy of the Portfolio, the
               Portfolio  may invest  all of its net  investable  assets  (cash,
               securities and receivables relating to securities) in an open-end
               management  investment  company  having  substantially  the  same
               investment objective, policies, and limitations as the Portfolio.

               All other fundamental  investment  policies and limitations,  and
          the  non-fundamental  investment  policies  and  limitations,  of each
          Portfolio  and its  corresponding  Series  are  identical.  Therefore,
          although  the  following   discusses  the   investment   policies  and
          limitations of the Series,  it applies equally to their  corresponding
          Portfolios.  Because each Portfolio  invests all of its net investable
          assets in its  corresponding  Series,  however,  a Series'  investment
          policies and  limitations  govern the type of investments in which the
          corresponding Portfolio has an indirect interest.

               For purposes of the  investment  limitation on  concentration  in
          particular  industries,  N&B  Management  identifies the "issuer" of a
          municipal  obligation that is not a general obligation note or bond on
          the basis of the obligation's characteristics. The most significant of
          these  characteristics  is the  source  of funds  for the  payment  of
          principal and interest on the  obligation.  If an obligation is backed
          by an irrevocable  letter of credit or other guarantee,  without which
          the  obligation  would not qualify for  purchase  under a  Portfolio's
          quality  restrictions,  an  issuer  of the  letter  of  credit  or the
          guarantee is considered an issuer of the obligation.  If an obligation
          meets  the  quality   restrictions   of  AMT  Limited   Maturity  Bond
          Investments and AMT Balanced  Investments without credit support,  the
          Series treats the commercial  developer or the industrial user, rather
          than the  governmental  entity or the guarantor,  as the issuer of the
          obligation,  even if the obligation is backed by a letter of credit or
          other guarantee.

               Except for the limitation on borrowing,  any investment policy or
          limitation that involves a maximum  percentage of securities or assets
          will not be considered to be violated unless the percentage limitation
          is exceeded  immediately  after,  and because of, a  transaction  by a
          Series.

               The Series'  fundamental  investment policies and limitations are
          as follows:

               1.  Borrowing.  Each Series may not borrow  money,  except that a
          Series may (i) borrow  money from  banks for  temporary  or  emergency
          purposes  and  not  for  leveraging  or  investment  (except  for  AMT
          International   Investments   which  may  borrow  for   leveraging  or
          investment, and AMT Government Income Investments which may borrow for
          any  purpose,  including  to meet  redemptions  or increase the amount
          available  for  investment)  and (ii)  enter into  reverse  repurchase
          agreements for any purpose;  provided that (i) and (ii) in combination
          do not exceed 33-1/3% of the value of its total assets  (including the
          amount borrowed) less liabilities  (other than borrowings).  If at any
          time borrowings exceed 33-1/3% of the value of a Series' total assets,
          the Series will reduce its  borrowings  within  three days  (excluding
          Sundays  and  holidays)  to the extent  necessary  to comply  with the
          33-1/3% limitation.

               2. Commodities. Each Series may not purchase physical commodities
          or contracts thereon,  unless acquired as a result of the ownership of
          securities or instruments,  but this restriction  shall not prohibit a
          Series from purchasing futures contracts or options (including options
          on  futures  (and,  with  respect  to AMT  International  Investments,
          foreign  currencies and forward  contracts)  but excluding  options or
          futures  contracts  on  physical  commodities)  or from  investing  in
          securities of any kind.

               3.  Diversification.  Each Series may not, with respect to 75% of
          the value of its total assets,  purchase the  securities of any issuer
          (other than securities issued or guaranteed by the U.S. Government, or
          any of its agencies or  instrumentalities)  if, as a result,  (i) more
          than 5% of the value of the Series'  total assets would be invested in
          the  securities of that issuer or (ii) the Series would hold more than
          10% of the outstanding voting securities of that issuer.

               4.  Industry  Concentration.  Each  Series may not  purchase  any
          security if, as a result,  25% or more of its total  assets  (taken at
          current  value) would be invested in the  securities of issuers having
          their  principal  business  activities  in  the  same  industry.  This
          limitation does not apply to purchases of (i) the securities issued or
          guaranteed   by   the   U.S.   Government,    or   its   agencies   or
          instrumentalities, (ii) investments by all Series (except AMT Partners
          Investments,  AMT Government Income  Investments and AMT International
          Investments) in certificates of deposit or bankers' acceptances issued
          by  domestic  branches  of U.S.  banks,  or (iii)  investments  by AMT
          Government Income Investments in mortgage- and asset-backed securities
          (regardless  of  whether  they are  issued or  guaranteed  by the U.S.
          Government or its agencies or instrumentalities). Mortgage- and asset-
          backed securities are considered to be a single industry.

               5.  Lending.  Each  Series may not lend any  security or make any
          other  loan if, as a result,  more than  33-1/3%  of its total  assets
          (taken at current  value)  would be lent to other  parties,  except in
          accordance with its investment objective,  policies,  and limitations,
          (I) through the  purchase of a portion of an issue of debt  securities
          or (ii) by engaging in repurchase agreements.

               6.  Real   Estate.   (All   Series   except   AMT   International
          Investments). Each Series may not purchase real estate unless acquired
          as a result of the ownership of securities  or  instruments,  but this
          restriction  shall not  prohibit a Series from  purchasing  securities
          issued by entities  or  investment  vehicles  that own or deal in real
          estate or interests therein,  or instruments secured by real estate or
          interests therein.

               (AMT  International  Investments).  The Series may not invest any
          part of its total  assets in real estate or  interests  in real estate
          unless  acquired  as a  result  of  the  ownership  of  securities  or
          instruments,  but this restriction  shall not prohibit the Series from
          purchasing  readily  marketable   securities  issued  by  entities  or
          investment  vehicles  that  own or deal in real  estate  or  interests
          therein or instruments secured by real estate or interests therein.

               7.   Senior Securities.   Each Series  may not  issue senior
          securities, except as permitted under the 1940 Act.

               8.        Underwriting.   Each  Series  may  not  underwrite
          securities of other issuers, except  to the extent that a Series,
          in  disposing of  portfolio securities,  may be  deemed to  be an
          underwriter  within  the meaning  of the  Securities Act  of 1933
          ("1933 Act").

               For purposes of fundamental investment limitation number 3 above,
          as  applied  to  AMT  Government  Income  Investments,  mortgage-  and
          asset-backed  securities will not be considered to have been issued by
          the  same  issuer  because  they  have  the  same  sponsor,  and  such
          securities issued by a finance or other single purpose subsidiary of a
          corporation that are not guaranteed by the parent  corporation will be
          considered  to be  issued  by  an  issuer  separate  from  the  parent
          corporation.

               The following non-fundamental investment policies and limitations
          apply to the Series:

               1.   Borrowing.   (All Series  except AMT  Government Income
          Investments and AMT International Investments).   Each Series may
          not purchase securities if outstanding  borrowings, including any
          reverse repurchase agreements, exceed 5% of its total assets.

               2.  Lending.  Except for the purchase of debt securities and
          engaging  in repurchase agreements, each  Series may not make any
          loans other than securities loans.

               3.    Investments  in  Other  Investment  Companies.    (AMT
          Partners Investments, AMT Government  Income Investments        
          and  AMT International   Investments).  Each   Series  may  not
          purchase securities of other  investment companies,  except to the
          extent permitted by the 1940  Act and in the open market at no
          more than customary brokerage commission  rates.  This limitation
          does not apply to securities  received or  acquired as dividends,
          offers  of  exchange,  or  as   a  result  of  a  reorganization,
          consolidation, or merger.

               4. Margin  Transactions.  Each Series may not purchase securities
          on  margin  from  brokers,  except  that  a  Series  may  obtain  such
          short-term  credits as are  necessary  for the clearance of securities
          transactions.  For all Series  except AMT  Liquid  Asset  Investments,
          margin payments in connection with  transactions in futures  contracts
          and options on futures  contracts shall not constitute the purchase of
          securities  on margin and shall not be deemed to violate the foregoing
          limitation.

               5.  Short  Sales.  (AMT  Liquid  Asset  Investments,  AMT  Growth
          Investments,         AMT Limited Maturity Bond Investments and        
          AMT Partners Investments).  Each Series may not sell securities short,
          unless  it owns or has the right to obtain  securities  equivalent  in
          kind and amount to the securities sold (or, in the case of AMT        
          Growth Investments, not more than 10% of the Series' net assets (taken
          at  current  value)  is held as  collateral  for such  sale at any one
          time).  Transactions  in  futures  contracts  and  options  shall  not
          constitute selling securities short.
   
               (AMT Balanced Investments). The Series will not engage in a short
          sale (except a short sale against-the-box) if, as a result, the dollar
          amount of all short sales will exceed 25% of its net assets, of if, as
          a  result,  the  value of  securities  of any one  issuer in which the
          Series  would be short will  exceed 2% of the value of the Series' net
          assets  or  2%  of  the   securities  of  any  class  of  any  issuer.
          Transactions in futures contracts and options are not considered short
          sales.
    
               (AMT  Government  Income  Investments).  The  Series may not sell
          securities  short,  unless it covers  the short  sale as  required  by
          current rules or positions of the Securities  and Exchange  Commission
          and its staff,  provided that the Series may not sell securities short
          if (i) the dollar amount of the short sales would exceed 5% of its net
          assets or (ii) the value of  securities of an issuer sold short by the
          Series  would  exceed the lesser of 2% of the Series' net assets or 2%
          of a class of the issuer's  outstanding  securities.  Transactions  in
          futures contracts and options shall not constitute  selling securities
          short.

               (AMT International Investments).  The Series will not engage in a
          short sale (except a short sale against-the-box), if, as a result, the
          dollar amount of all short sales will exceed 25% of its net assets, or
          if, as a result,  the value of  securities  of any one issuer in which
          the Series  would be short will  exceed 2% of the value of the Series'
          net  assets  or 2% of the  securities  of  any  class  of any  issuer.
          Transactions in forward foreign currency contracts,  futures contracts
          and options are not considered short sales.
   
               6.  Ownership of Portfolio  Securities  by Officers and Trustees.
          Each Series may not  purchase or retain the  securities  of any issuer
          if, to the  knowledge of the Series'  management,  those  officers and
          trustees of the Trusts and  officers and  directors of N&B  Management
          who  each own  individually  more  than  1/2 of 1% of the  outstanding
          securities  of  such  issuer,  together  own  more  than  5%  of  such
          securities.
    
       
               7.  Unseasoned   Issuers.   Each  Series  may  not  purchase  the
          securities of any issuer (other than  securities  issued or guaranteed
          by domestic or foreign governments or political  subdivisions thereof)
          if, as a result,  more than 5% of the Series'  total  assets  would be
          invested in the  securities of business  enterprises  that,  including
          predecessors,  have a record of less than  three  years of  continuous
          operation.  For AMT Government  Income  Investments,  this restriction
          does not apply to mortgage- and asset-backed securities.

               8. Illiquid Securities. Each Series may not purchase any security
          if, as a result,  more than 10% of its net assets would be invested in
          illiquid  securities.  Illiquid  securities  include  securities  that
          cannot be sold within  seven days in the  ordinary  course of business
          for  approximately  the  amount at which the  Series  has  valued  the
          securities,  such as repurchase agreements maturing in more than seven
          days.

               9.  Restricted Securities.  (AMT International Investments).
          The Series  may not purchase  a security restricted as  to resale
          if,  as a  result thereof,  more than  10% of  the  Series' total
          assets would be  invested in  restricted securities.   Securities
          that can be sold freely in the principal market in which they are
          traded are not considered restricted, even if they cannot be sold
          in the U.S.

               10.  Warrants.  (AMT  International  Investments and AMT Balanced
          Investments).       Each Series may not invest more than 5% of its net
          assets in warrants, whether or not such warrants are listed on the New
          York Stock Exchange ("NYSE") or the American Stock Exchange  ("AmEx"),
          or more than 2% of its net assets in unlisted  warrants.  For purposes
          of this limitation, warrants are valued at the lower of cost or market
          value and  warrants  acquired  by the Series in units or  attached  to
          securities  are deemed to be without  value,  even if the warrants are
          later separated from the unit.

               11.  Oil  and  Gas  Programs.  (AMT  Partners  Investments,   AMT
          Government Income Investments,  AMT International  Investments and AMT
          Balanced Investments). Each Series may not invest in participations or
          other  direct  interests  in oil,  gas,  or other  mineral  leases  or
          exploration  or  development  programs,  (but  each  of  AMT  Partners
          Investments and AMT International  Investments may purchase securities
          of companies that own interests in any of the foregoing).

               12.  Real  Estate.  (AMT Government  Income Investments, AMT
          International Investments and AMT         Balanced Investments).
          Each Series may not invest in real estate limited partnerships.

               13. Investments in  Any One Issuer.   (AMT Government Income
          Investments).  The Series may  not purchase the securities of any
          one issuer  (other than securities  issued or  guaranteed by  the
          U.S.  Government or any of its agencies or instrumentalities) if,
          as a result,  more than 5% of  the Series' total assets  would be
          invested in the securities of that issuer.

               (AMT International Investments).  At the close of each quarter of
          the Series'  taxable  year,  (i) no more than 25% of its total  assets
          will be invested in the securities of a single  issuer,  and (ii) with
          regard to 50% of its total assets, no more than 5% of its total assets
          will  be  invested  in  the  securities  of  a  single  issuer.  These
          limitations do not apply to U.S. government securities, as defined for
          tax purposes.

               14.  Puts,   Calls,   Straddles,   or  Spreads.   (AMT   Partners
          Investments).  The Series may not  invest in puts,  calls,  straddles,
          spreads,  or any combination  thereof,  except that the Series may (i)
          write (sell) covered call options against portfolio  securities having
          a market value not  exceeding  10% of its net assets and (ii) purchase
          call  options in related  closing  transactions.  The Series  does not
          construe the foregoing  limitation  to preclude it from  purchasing or
          writing options on futures contracts.

               15.   Foreign Securities.  (AMT Partners  Investments).  The
          Series may  not invest more  than 10% of  the value of  its total
          assets  in  securities  of foreign  issuers,  provided  that this
          limitation shall not  apply to foreign securities  denominated in
          U.S. dollars.

               Rating Agencies. As discussed in the Prospectus,  each Series may
          purchase  securities rated by Standard & Poor's Ratings Group ("S&P"),
          Moody's Investors Service, Inc.  ("Moody's"),  or any other nationally
          recognized statistical rating organization  ("NRSRO").  The ratings of
          an NRSRO  represent  its  opinion as to the quality of  securities  it
          undertakes  to rate.  Ratings are not  absolute  standards of quality;
          consequently,  securities with the same maturity,  coupon,  and rating
          may have different yields. Among the NRSROs, the Series rely primarily
          on  ratings  assigned  by S&P and  Moody's,  which  are  described  in
          Appendix A to this SAI.
   
               International Investing - AMT International  Investments.  Equity
          portfolios  consisting solely of domestic investments have not enjoyed
          the higher  returns  foreign  opportunities  can offer.  For more than
          thirty years, for example,  the growth rate of many foreign  economies
          has outpaced that of the U.S. While the U.S.  accounted for almost 66%
          of the world's  total  securities  market  capitalization  in 1970, it
          accounted for less than 37% of that total at the end of 1994 - or less
          than half of the  dollar  value of the  world's  available  stocks and
          bonds today (source: Morgan Stanley Capital International).
    
               Over  time,  a  number  of  international   equity  markets  have
          outperformed   their  U.S.   counterparts.   Although   there  are  no
          guarantees,  foreign  markets  could  continue  to provide  attractive
          investment opportunities.
       
   
               In addition,  according to Morgan Stanley Capital  International,
          the leading  companies in any given sector are not always  U.S.-based.
          For  example,  22 of the  largest 25  automobile  companies  are based
          outside the United States, as are 20 of the top 25 banks.
    
               A principal advantage of investing overseas is diversification. A
          diversified  portfolio  gives  investors  the  opportunity  to  pursue
          increased  overall  return  while  reducing  risk.  It is  prudent  to
          diversify by taking advantage of investment opportunities in more than
          one country's stock or bond market.  By investing in several countries
          through a worldwide portfolio,  investors can lower their exposure and
          vulnerability  to  weakness  in any one  market.  Investors  should be
          aware,  however,  that  international  investing  is  not a  guarantee
          against market risk and may be affected by economic factors  described
          in the Prospectus,  such as the prospects of individual companies, and
          other risks such as currency fluctuations or controls,  expropriation,
          nationalization and confiscatory taxation.

               Furthermore,  for the individual investor,  buying foreign stocks
          and  bonds  can be  difficult,  involving  many  decisions.  Accessing
          international markets is complicated; few individuals have the time or
          resources to thoroughly evaluate foreign companies and markets, or the
          ability to incur the high  transaction  costs of direct  investment in
          such markets.  A mutual fund investing in foreign securities offers an
          investor broad diversification at a relatively low cost.

               AMT  International   Investments   invests  primarily  in  equity
          securities of companies  located in developed  foreign  economies,  as
          well as in the "emerging markets." In all cases the investment process
          of the Series'  Investment Adviser includes a combination of "top-down
          country allocation" and "bottom-up security selection."

          Top-down approach to regional and country diversification
   
               N&B  Management  uses  extensive  economic  research  to identify
          countries that offer attractive investment opportunities, by analyzing
          factors such as Gross  Domestic  Product  growth rates,  interest rate
          trends, and currency exchange rates. Market valuations,  combined with
          correlation and volatility comparisons,  provide N&B Management with a
          target allocation across 20 or more countries.
    
          Bottom-up approach to security selection
   
               N&B Management  value-driven style seeks out attractively  priced
          issues, by concentrating on criteria such as a low price-  to-earnings
          ratio relative to earnings growth rate,  balance sheet  strength,  low
          price  to cash  flow,  and  management  quality.  Typically,  over 100
          individual  issues will comprise the portfolio.  The portfolio will be
          comprised of medium- to large capitalization  companies in relation to
          each individual national market.
    
          Currency Risk Management - AMT International Investments
   
               Exchange rate movements and  volatility are important  factors in
          international  investing. N&B Management believes in actively managing
          the Series' currency  exposure,  in an effort to capitalize on foreign
          currency trends and to reduce overall portfolio  volatility.  Currency
          risk  management is performed  separately  from equity  analysis.  N&B
          Management  intends to use a combination of economic analysis to guide
          the Series'  longer-term  posture and  quantitative  trend analysis to
          assist in timing decisions with respect to whether (or when) to invest
          in  instruments  denominated  in a  particular  foreign  currency,  or
          whether  (or when) to hedge  particular  foreign  currencies  in which
          liquid foreign exchange markets exist.
    
          Discussions With Portfolio Managers

          An  Interview  with  Felix  Rovelli,  Portfolio  Manager  of  AMT
          International Investments

               Q:  Why should investors  allocate a portion of their assets
          to international markets?
   
               A: First, an investor who does not invest  internationally misses
          out on  more  than  two-thirds  of the  world's  potential  investment
          opportunities.  The U.S.  stock  market  today  represents  less  than
          one-half  of the world's  stock  market  capitalization,  and the U S.
          portion  continues  to  shrink  as other  countries  around  the world
          introduce or expand the size of their equity  markets.  Privatizations
          of government-owned  corporations,  initial public offerings,  and the
          occasional  creation of official stock exchanges in emerging economies
          continuously  present new  opportunities  for capital in an  expanding
          global market.
    
               Second,   many  foreign   economies  are  in  earlier  stages  of
          development than ours and are growing fast.  Economic growth can often
          mean potential for investment growth.

               Finally,  international  investing  helps  an  investor  increase
          diversification  and can reduce  risk.  Domestic  and foreign  markets
          generally  do not all  move in the  same  direction,  so  gains in one
          market may offset losses in another.

               Q:  Does international investing involve special risks?

               A: Currency risk is one important risk presented by international
          investing.  Fluctuations in exchange rates can either add to or reduce
          an  investor's  returns,  a fact that  anyone  who  invests in foreign
          markets should keep in mind.

               Other  risks  include,  but are not limited  to,  greater  market
          volatility,  less government  supervision  and  availability of public
          information  and the  possibility  of adverse  economic  or  political
          developments.  The special risks of foreign investing are discussed in
          greater detail in the Prospectus.

               Q:   What are  some of  the  advantages of  investing in  an
          international fund?

               A:  An international mutual fund can  be a convenient way to
          invest internationally and diversify assets among several markets
          to reduce risk.

               Additionally,   the  considerable  burden  of  obtaining  timely,
          accurate and  comprehensive  information  about foreign  economies and
          securities is left to seasoned professional managers.
   
               Over the past decade,  one of the major indices of  international
          stocks  outperformed the S&P 500 Index, which represents an average of
          the prices of certain major U.S. stocks.

               If you had invested $10,000 in the  international and U.S. stocks
          comprising  both indices ten years ago,  here's what your  investments
          would have been worth as of June 30, 1995.1

                                         Value of       Avg.
                                         investment     annualized
                                                        total return
           International stocks (EAFE)   $45,587        16.38%

           Domestic stocks (S&P 500)     $39,131        14.62%


               Of course,  these  historical  results  may not  continue  in the
          future  and  cannot   predict  or  reflect  the   performance  of  AMT
          International Investments. In addition,  investors should keep in mind
          the added risks inherent in foreign markets, such as currency exchange
          fluctuations,  interest rates, and economic and political  conditions,
          all of which can lead to a greater  degree of  volatility  than  funds
          that invest primarily in U.S. stocks.
    
               Q:  What is your investment approach?
   
               A: N&B Management seeks to capitalize on investments in countries
          where  positive  economic and political  factors are likely to produce
          above-average  returns.  Studies  have  shown that the  allocation  of
          assets  among  countries  is  typically  the  most  important   factor
          contributing to portfolio performance. N&B Management believes that in
          the long term, a nation's  economic  growth and the performance of its
          equity market are highly  correlated.  Therefore,  N&B Management will
          continuously   evaluate  the  global  economic   outlook  as  well  as
          individual country data to guide country allocation.  Our process also
          leads to diversification across many countries,  typically 20 or more,
          in an effort to limit total portfolio risk.

<PAGE>
   
               N&B Management strives to invest in companies within the selected
          countries that are in the best position to capitalize on such positive
          developments  or  companies  that are most  attractively  valued.  N&B
          Management  will  usually  include  in  the  Series'  investments  the
          securities  of  large-capitalization  companies  in  relation  to each
          individual  national market, as well as securities of  faster-growing,
          medium-sized  companies that offer potentially  higher returns but are
          often associated with higher risk.

               The  criteria  for security  selection  focus on  companies  with
          leadership in specific  markets or niches within specific  industries,
          which appear to exhibit  positive  fundamentals,  and seem undervalued
          relative to their  earnings  potential  or the worth of their  assets.
          Typically,   in  emerging  markets,  N&B  Management  will  invest  in
          relatively large,  established companies which N&B Management believes
          possess the managerial,  financial,  and marketing strength to exploit
          successfully  the  growth  of a  dynamic  economy.  In more  developed
          markets,  such as Europe and Japan,  the Series may invest to a higher
          degree in  medium-sized  companies.  Medium-sized  companies can often
          provide  above  average  growth,  and  are  less  followed  by  market
          analysts, a fact that sometimes leads to inefficient valuation.

               Finally,  N&B  Management  will strive to limit  total  portfolio
          volatility  and increase  returns by  selectively  hedging the Series'
          foreign  currency  exposure in times when N&B  Management  expects the
          U.S. Dollar to strengthen.
    
               Q:  How do you perceive the current outlook?

               A:  There  is  still  an   abundance   of   exciting   investment
          opportunities  around the world.  Many equity  markets  still have not
          reached the maturity stage of the U.S.  market and have much more room
          to grow.  There are new markets opening up to foreign  investments and
          many changes are  occurring in markets where equity  investments  have
          traditionally commanded less attention than fixed-income securities.
   
               In  addition,  it appears  that both  Europe  and Japan  recently
          passed the bottom of their economic  cycles.  In many  economies,  the
          current  recession  has been the most severe of all  recessions in the
          last  five  decades.  With  global  inflation  still  in  check,  many
          economies should continue to have lower interest rates, which, coupled
          with a forecast of recovery in profits,  could positively impact stock
          market returns.

          Timely  Opportunity  for  Investors   Looking  for  International
          Bargains

               "If you have most of your money in U.S. stocks, now may be a good
          time to shift part of your portfolio abroad." The Wall Street Journal,
          July 25, 1995.

               While the U.S. stock market has been reaching new highs in recent
          months, you may be able to find more bargains in international  stocks
          than you may locate on Wall  Street.  "Today,  we are  finding a large
          supply of what we believe to be excellent  companies  whose stocks are
          priced at very low levels," explains Felix Rovelli,  portfolio manager
          for AMT International  Investments,  a fund that invests in the stocks
          of companies outside the United States.

               "For the past year, " Rovelli  continues,  "the economies of many
          countries  have been growing,  and the  fundamentals  of many selected
          individual  company stocks have looked strong. Yet because of concerns
          -- over  Mexico and the falling  U.S.  dollar,  among other  things --
          international stock prices have lagged.
          That is, until recently."

               After facing  setbacks in 1994 and earlier  this year,  plenty of
          regions outside the United States have begun to bounce back.

               In its June  1995  quarterly  report on  mutual  funds,  The Wall
          Street Journal  reported that stock markets in both emerging areas and
          developed European countries rebounded strongly from April 1st to June
          30th.2 (f/n July 7, 1995. Drawn from data supplied by

          Lipper Analytical Services.)

               What is causing this  apparent  turnaround?  France,  Italy,  and
          other European  countries have been  recovering  from  recessions.  In
          developing  countries  like Thailand and Malaysia,  the economies have
          been moving ahead at impressive  growth rates of 6% to 10% annually --
          over twice the U.S. rate.

               AMT International  Investments searches far and wide for the best
          bargains outside the United States.

               Without  restrictions  as to  regions,  portfolio  manager  Felix
          Rovelli can exploit  investment  opportunities  wherever  and whenever
          they arise -- in both developed and emerging economies.  He invests in
          the stocks of companies with solid fundamentals that he believes to be
          undervalued   and  to  have   above-average   potential   for  capital
          appreciation.

          Theresa A. Havell and Thomas  G. Wolfe: Portfolio Managers of AMT
          Limited  Maturity Bond  Investments and AMT  Balanced Investments
          (debt securities portion);  and Theresa A. Havell and  William C.
          Cunningham:    Portfolio  Managers   of  AMT  Government   Income
          Investments.

               Investors  are  accustomed  to thinking of yield or interest rate
          figures  as the same as total  return  on  their  investment,  because
          savings accounts,  conventional  money market funds, and Cds do indeed
          return the stated  yield.  But bond funds are  different  -- bonds not
          only pay  interest,  they also  fluctuate  in value.  For  example,  a
          decline in prevailing levels of interest rates generally increases the
          value of debt securities in a bond fund's portfolio, while an increase
          in rates usually reduces the value of those  securities.  As a result,
          interest rate  fluctuations  will affect a fund's net asset value (and
          total  return)  but not the  income  received  by the  fund  from  its
          portfolio  securities.  Both the yield and risk to  principal  usually
          increase as the maturity of the bond increases.
    
               So looking at yield alone  carries  high risk because the highest
          yielding  bonds  historically  tend to be the ones  with  the  longest
          maturities.  The risk to  principal  in these  bonds  can be nearly as
          great as the risk in stocks and may not produce the same reward.
   
               What advice  does Ms.  Theresa  Havell,  the manager of the Fixed
          Income Group of Neuberger&Berman,  L.P. have for investors seeking the
          highest  returns  on their  fixed  income  investments?  "Look  beyond
          interest  rates to total  return,"  she  states  unequivocally.  Total
          return  includes  the yield from the bond and the increase or decrease
          in the market value (price) of the bond.
    
               "Once you  consider the risk to  principal,  then total return is
          the only concept  that can measure what you are actually  earning from
          your fixed income securities," Ms. Havell says.
   
               The Limited Maturity Bond Portfolio is intended for investors who
          seek the highest  current  income with less  volatility  and risk than
          that of a longer-term  bond fund. Both the yield and risk to principal
          usually   increase  as  the  maturity  of  the  bond  increases.   The
          Portfolio's   corresponding   Series   provides  active  fixed  income
          portfolio  management through investment in securities with an average
          portfolio duration of no longer than four years. Studies of historical
          bond returns have shown that risk-adjusted  total returns were best in
          bonds  having  durations  of two to  five  years.  The  bonds  in this
          duration  range  have  provided   significantly  higher  returns  than
          shorter-term  securities  and  nearly the same  return as  longer-term
          fixed  income  securities  with far  less  volatility.  The  Portfolio
          Managers  attempt to increase the Series'  value by actively  managing
          duration in response to interest rate trends and fundamental  economic
          developments.  They seek to protect  principal by shortening  duration
          when  interest  rates are rising and  enhance  returns by  lengthening
          duration in a falling interest rate market.

               AMT Limited  Maturity Bond  Investments  also enhances return and
          limits risk by  following  a broadly  diversified  investment  program
          across the  various  sectors  of the fixed  income  market.  Over long
          periods of time,  corporate,  mortgage-  and  asset-backed  bonds have
          provided higher returns than Treasury securities. Relying on extensive
          internal  research,  the  Portfolio  Managers  attempt to increase the
          value of the Series by  purchasing  securities  at  significant  yield
          premiums to Treasury  bonds.  N&B Management  uses sector  weightings,
          which are based on an  analysis  of the key  factors  that it believes
          will impact the relative value and risk for each sector. These factors
          include the economic  cycle,  credit quality trends and  supply/demand
          analysis for each security type.  Within the sectors found attractive,
          individual  bonds are  rigorously  analyzed for credit,  cash flow and
          liquidity  risk.  Those that  appear to offer  attractive  risk reward
          ratios are  purchased.  While overall  portfolio  quality is high, N&B
          Management  believes that by careful  evaluation  of credit risk,  the
          Series  benefits  from the  inclusion  of lower- rated bonds with only
          moderate incremental risk.

               In the debt securities  portion of its investments,  AMT Balanced
          Investments  will utilize the same approach and investment  techniques
          employed by N&B  Management  in managing  AMT  Limited  Maturity  Bond
          Investments.

               The  Government  Income  Portfolio is designed for  investors who
          seek a higher  level of income and total  return than money  market or
          short-to-intermediate  bond funds generally provide and are willing to
          accept more principal  fluctuation in order to achieve that objective.
          N&B Management  follows a flexible  investment  strategy  depending on
          market  conditions  and  interest  rate  trends.   This  opportunistic
          strategy looks  aggressively for  opportunities to maximize income and
          total  return by adjusting  the duration to take maximum  advantage of
          interest  rates.  The  Government  Income  Portfolio may be a suitable
          complement to lower risk,  lower return bond funds and a complement to
          an equity fund portfolio.  On a risk level,  longer-term  bonds have a
          standard deviation between common stocks (represented by the S&P "500"
          Composite Stock Price Index ("S&P 500 Index")) and intermediate-  term
          5-year  U.S.  Treasury  Bonds.  Standard  deviation  is a  statistical
          measure of the degree to which the value of an individual security may
          vary (or deviate) from the mean.

               At times,  N&B Management may use the concept of "duration"  when
          describing   the   investment   program  of  AMT   Government   Income
          Investments.  Duration  is a measure of the  expected  life of a fixed
          income security and is an indicator of a security's price "volatility"
          or "risk"  associated with changes in interest  rates.  Whereas a debt
          security's  "term to maturity"  measures only the time until the final
          payment  thereon is made,  its  duration  also takes into  account the
          present  value of each  payment  thereunder  expected  to be  received
          through maturity.
    
          Mark R. Goldstein, Portfolio Manager of AMT Growth Investments.

               The  investment  objective of AMT Growth  Investments  is capital
          appreciation,  without regard to income.  "The Series differs from the
          other   Series  in  its   willingness   to   invest  in  stocks   with
          price/earnings ratios or price-to-cash-flow ratios that are reasonable
          relative  to a  company's  growth  prospects  and that of the  general
          market," says Mark Goldstein, its portfolio manager. Mr. Goldstein has
          consistently  followed  this  approach as a  portfolio  manager at N&B
          Management.  He looks for stocks of financially sound companies with a
          special  market  capability,  a competitive  advantage or product that
          makes them  particularly  attractive  over the long term, but likes to
          purchase  them at a reasonable  price  relative to their growth rates.
          Mr.  Goldstein  calls this  approach  "GARP" -- growth at a reasonable
          price. "An investor  shouldn't try to beat the market by trading funds
          like stocks. The hardest thing to do -- but the best thing to do -- is
          to put in some money when the market is down and keep it there. That's
          how one really  builds wealth over the long term -- a mutual fund is a
          great long-term investment."
   
               "We view value both on a relative  and an absolute  basis,  so we
          may buy stocks with somewhat  above-market  historical  growth rates,"
          Mr. Goldstein explains. "We also tend to stay more fully invested when
          we think the market is attractive for quality growth companies. But we
          will get out of  stocks  and into  cash  when we  think  there  are no
          reasonable values available."

               In the common  stock  portion of its  investments,  AMT  Balanced
          Investments  will utilize the same approach and investment  techniques
          employed by N&B Management in managing AMT Growth Investments.
    
   
          Michael M.  Kassen and  Robert I.  Gendelman, Co-Managers of  AMT
          Partners Investments

               "The investment  objective of AMT Partners Investments is capital
          growth," say its co-managers Michael Kassen and Robert Gendelman.  "We
          want to make money in good  markets and not give up those gains during
          rough times."

               "Our investors seek  consistent  performance  and have a moderate
          risk  tolerance.  They do know,  however,  that stock  investments can
          provide the  long-term  upside  potential  essential to meeting  their
          long-term investment goals,  particularly a comfortable retirement and
          planning for a college education."
    
   
               "We look for  stocks  that are  undervalued  in the  market-place
          either  in  relation  to  strong  current  fundamentals,  such  as low
          price-to-earnings ratios, consistent cash flow, and support from asset
          values,  or in relation  to the growth of their  future  earnings,  as
          projected by N&B Management.  If the market goes down, those stocks we
          elect to hold, historically, go down less."

               The  co-portfolio  managers  monitor  stocks  of medium to large-
          sized  companies  that  often  are not  closely  scrutinized  by other
          investors. The managers research these companies in order to determine
          if they will produce a new product,  become an acquisition  target, or
          undergo a financial restructuring.

               What else  catches Mr.  Kassen's and  Mr. Gendelman's  eyes?
          "We like managements  that own their own stock.   These companies
          usually seek to build shareholder wealth by buying back shares or
          making acquisitions that have a  swift and positive impact on the
          bottom line."

               To  increase  the  upside  potential,  the  managers  zero  in on
          companies that dominate their industries or their specialized  niches.
          Their  reasoning?  "Market  leaders  tend to  earn  higher  levels  of
          profits."

               AMT Partners  Investments  invests in a wide array of stocks, and
          no single  stock  makes up more than a small  fraction  of the Series'
          total assets. Of course, the Series' holdings are subject to change.
    
          Additional Investment Information

               Some or all of the  Series,  as  indicated  below,  may  make the
          following  investments,  among others although they may not buy all of
          the types of securities, or use all of the investment techniques, that
          are described.
   
               Repurchase  Agreements.  (All Series).  Repurchase agreements are
          agreements under which a Series purchases  securities from a bank that
          is a member of the  Federal  Reserve  System  (or with  respect to AMT
          International  Investments,  from a foreign  bank or a U.S.  branch or
          agency of a foreign  bank),  or a  securities  dealer,  that agrees to
          repurchase  the  securities  from the  Series  at a higher  price on a
          designated  future date.  Repurchase  agreements  generally  are for a
          short period of time,  usually less than a week.  No Series will enter
          into a  repurchase  agreement  with a  maturity  of  more  than  seven
          business  days if, as a result,  more than 10% of the value of its net
          assets would then be invested in such repurchase  agreements and other
          illiquid  securities.  A Series will enter into a repurchase agreement
          only if (1)  the  underlying  securities  are of the  type  (excluding
          maturity or duration limitations) that the Series' investment policies
          and limitations  would allow it to purchase  directly,  (2) the market
          value of the underlying securities, including accrued interest, at all
          times equals or exceeds the value of the repurchase agreement, and (3)
          payment for the underlying  securities is made only upon  satisfactory
          evidence that the securities are being held for the Series' account by
          the custodian or a bank acting as the Series' agent.
    
   
               Securities Loans. (All Series).  In order to realize income, each
          Series  may  lend  portfolio  securities  with a value  not  exceeding
          33-1/3%  of  its  total   assets  to  banks,   brokerage   firms,   or
          institutional   investors  judged   creditworthy  by  N&B  Management.
          Borrowers are required  continuously  to secure their  obligations  to
          return  securities on loan from the Series by  depositing  collateral,
          which  will be marked  to market  daily,  in a form  determined  to be
          satisfactory  by the Series Trustees and equal to at least 100% of the
          market  value of the loaned  securities,  which will also be marked to
          market  daily.  N&B  Management  believes  the  risk of loss on  these
          transactions is slight because,  if a borrower were to default for any
          reason, the collateral should satisfy the obligation. However, as with
          other  extensions  of secured  credit,  loans of portfolio  securities
          involve  some  risk of loss of  rights in the  collateral  should  the
          borrower fail financially.
    
   
               Restricted  Securities  and Rule 144A  Securities.  (All Series).
          Each Series may invest in restricted securities,  which are securities
          that may not be sold to the public  without an effective  registration
          statement under the 1933 Act or, if they are unregistered, may be sold
          only in a privately negotiated transaction or pursuant to an exemption
          from registration.  In recognition of the increased size and liquidity
          of the  institutional  markets  for  unregistered  securities  and the
          importance of institutional investors in the formation of capital, the
          SEC has  adopted  Rule 144A under the 1933 Act,  which is  designed to
          further facilitate efficient trading among institutional  investors by
          permitting  the sale of certain  unregistered  securities to qualified
          institutional  buyers.  To the extent privately placed securities held
          by a Series  qualify  under Rule  144A,  and an  institutional  market
          develops  for those  securities,  the  Series  likely  will be able to
          dispose of the securities without registering them under the 1933 Act.
          To  the  extent  that   institutional   buyers  become,  for  a  time,
          uninterested in purchasing  these  securities,  investing in Rule 144A
          securities  could have the effect of increasing the level of a Series'
          illiquidity.  N&B Management,  acting under guidelines  established by
          the Series Trustees,  may determine that certain securities  qualified
          for trading under Rule 144A are liquid. Foreign securities that can be
          freely  sold in the markets in which they are  principally  traded are
          not  considered by a Series to be  restricted.  Regulation S under the
          1933 Act permits the sale abroad of securities that are not registered
          for sale in the U.S.
    
               Where registration is required,  a Series may be obligated to pay
          all or part of the registration  expenses,  and a considerable  period
          may elapse between the decision to sell and the time the Series may be
          permitted  to  sell  a  security   under  an  effective   registration
          statement. If, during such a period, adverse market conditions were to
          develop, the Series might obtain a less favorable price than prevailed
          when it decided to sell. To the extent  privately  placed  securities,
          including Rule 144A securities,  are illiquid,  purchases thereof will
          be  subject  to each  Series'  10% limit on  investments  in  illiquid
          securities.  Restricted  securities  for  which no market  exists  are
          priced at fair  value as  determined  in  accordance  with  procedures
          approved and periodically reviewed by the Series Trustees.

               Reverse Repurchase Agreements. (All Series). A reverse repurchase
          agreement  involves a Series' sale of portfolio  securities subject to
          its agreement to repurchase the securities at a later date for a fixed
          price  reflecting  a market rate of  interest;  these  agreements  are
          considered   borrowings  for  purposes  of  each  Series'   investment
          limitations  and  policies  concerning  borrowings.  While  a  reverse
          repurchase  agreement is outstanding,  a Series will maintain with its
          custodian in a segregated  account  cash,  U.S.  Government  or Agency
          Securities,  or other liquid,  high-grade debt  securities,  marked to
          market daily,  in an amount at least equal to the Series'  obligations
          under  the  agreement.  There  is a risk  that the  contra-party  to a
          reverse  repurchase  agreement will be unable or unwilling to complete
          the  transaction  as  scheduled,  which  may  result  in losses to the
          Series.
   
               Banking and Savings  Institution  Securities.  (AMT Liquid  Asset
          Investments,  AMT Limited  Maturity Bond  Investments,  AMT Government
          Income Investments and AMT Balanced Investments). Each of these Series
          may invest in  banking  and  savings  institution  obligations,  which
          include Cds, time deposits, bankers' acceptances, and other short-term
          debt  obligations  issued by commercial  banks and Cds, time deposits,
          and other short-term  obligations issued by savings institutions.  Cds
          are receipts for funds  deposited for a specified  period of time at a
          specified rate of return;  time deposits generally are similar to Cds,
          but are uncertificated; and bankers' acceptances are time drafts drawn
          on  commercial   banks  by  borrowers,   usually  in  connection  with
          international  commercial  transactions.  The Cds, time deposits,  and
          bankers'  acceptances  in which a  Series  invests  typically  are not
          covered by deposit insurance.
    
               These Series may invest in securities issued by a commercial bank
          or savings  institution  only if (1) the bank or institution has total
          assets of at least  $1,000,000,000,  (2) the bank or institution is on
          N&B  Management's  approved  list,  (3) in the case of a U.S.  bank or
          institution, its deposits are insured by the Federal Deposit Insurance
          Corporation, and (4) in the case of a foreign bank or institution, the
          securities are, in N&B Management's  opinion, of an investment quality
          comparable  with other debt  securities  that may be  purchased by the
          Series.  These  limitations do not prohibit  investments in securities
          issued by  foreign  branches  of U.S.  banks  that meet the  foregoing
          requirements.  These Series (except AMT Government Income Investments)
          do not currently  intend to invest in any security issued by a foreign
          savings institution.

               Leverage.  (AMT  International  Investments  and  AMT  Government
          Income  Investments).  Each of these Series may make  investments when
          borrowings are outstanding. Leveraging a Series creates an opportunity
          for increased net income but, at the same time,  creates  special risk
          considerations.  For example, leveraging may exaggerate changes in the
          net asset  value of  Portfolio  shares and in the  Portfolio's  yield.
          Although the  principal of such  borrowings  will be fixed,  a Series'
          assets  may  change  in  value  during  the  time  the   borrowing  is
          outstanding.  Leveraging  will create  interest  expenses for a Series
          which can exceed the income  from the assets  retained.  To the extent
          the income  derived from  securities  purchased  with  borrowed  funds
          exceeds the interest a Series will have to pay, the Series' net income
          will  be  greater  than it  would  be if  leveraging  were  not  used.
          Conversely, if the income from the assets retained with borrowed funds
          is not sufficient to cover the cost of  leveraging,  the net income of
          the  Series  will be less  than  if  leveraging  were  not  used,  and
          therefore the amount  available for  distribution  to  stockholders as
          dividends  will be  reduced.  Reverse  repurchase  agreements  which a
          Series does not fully  collateralize  create  leverage,  a speculative
          factor,  and will also be considered as borrowings for purposes of the
          Series' investment limitations.

               Generally,  each of these  Series does not intend to use leverage
          for investment purposes.  AMT International  Investments may, however,
          use  leverage to purchase  securities  needed to close out short sales
          entered into for hedging  purposes  and to  facilitate  other  hedging
          transactions.
   
               Foreign Securities.  (All Series).  Each of the Series may invest
          in  U.S.  dollar-denominated  securities  issued  by  foreign  issuers
          (including  governments,  quasi-governments  and,  with respect to AMT
          International Investments,  banks) and foreign branches of U.S. banks,
          including  negotiable Cds,  commercial  paper and, with respect to AMT
          International Investments, bankers' acceptances. These investments are
          subject to each Series'  quality and, in the case of each fixed income
          Series, their maturity or duration standards.
    
               While  investments  in foreign  securities are intended to reduce
          risk by providing further  diversification (with respect to all Series
          but AMT International Investments), such investments involve sovereign
          and other risks,  in addition to the credit and market risks  normally
          associated with domestic  securities.  These  additional risks include
          the  possibility  of  adverse  political  and  economic   developments
          (including political  instability) and the potentially adverse effects
          of unavailability of public  information  regarding  issuers,  reduced
          governmental   supervision   regarding   financial  markets,   reduced
          liquidity  of  certain  financial  markets,  and the  lack of  uniform
          accounting,  auditing,  and financial  standards or the application of
          standards  that are different or less  stringent than those applied in
          the U.S.
   
               Each Series (except AMT Liquid Asset  Investments)  may invest in
          equity  (except  AMT  Government  Income  Investments  and AMT Limited
          Maturity Bond Investments), debt, or other income-producing securities
          of issuers in countries whose governments are considered stable by N&B
          Management that are  denominated in or indexed to foreign  currencies,
          including,  but not limited to, (1) common and preferred stocks,  with
          respect to all Series except AMT Government Income Investments and AMT
          Limited  Maturity Bond  Investments (2) convertible  securities,  with
          respect  to  AMT   Balanced,   Growth,   Partners  and   International
          Investments (3) warrants (subject to non-fundamental limitation number
          10), with respect to AMT International Investments (4) Cds, commercial
          paper, fixed-time deposits, and bankers' acceptances issued by foreign
          banks, (5) obligations of other  corporations,  and (6) obligations of
          foreign   governments,   or   their   subdivisions,    agencies,   and
          instrumentalities, international agencies, and supranational entities.
          Investing in these  securities  includes the special risks  associated
          with  investing  in  non-U.S.   issuers  described  in  the  preceding
          paragraph   and  the   additional   risks   of  (1)   nationalization,
          expropriation,  or  confiscatory  taxation,  (2)  adverse  changes  in
          investment or exchange control  regulations  (which could prevent cash
          from  being  brought  back  to the  U.S.),  and (3)  expropriation  or
          nationalization   of  foreign   portfolio   companies.   Additionally,
          dividends and interest payable on foreign securities may be subject to
          foreign taxes, including taxes withheld from those payments, and there
          are   generally   higher   commission   rates  on  foreign   portfolio
          transactions.  Fixed commissions on foreign  securities  exchanges are
          generally  higher  than  negotiated  commissions  on  U.S.  exchanges,
          although  each  Series  endeavors  to achieve the most  favorable  net
          results on portfolio transactions.  There is generally less government
          supervision and regulation of securities exchanges,  brokers,  dealers
          and listed  companies  than in the U.S. Mail service  between the U.S.
          and foreign  countries  may be slower or less reliable than within the
          United  States,  thus  increasing  the risk of delayed  settlements of
          portfolio   transactions  or  loss  of   certificates   for  portfolio
          securities.
    
               Prices of  foreign  securities  and  exchange  rates for  foreign
          currencies may be affected by the interest  rates  prevailing in other
          countries. The interest rates in other countries are often affected by
          local factors, including the strength of the local economy, the demand
          for borrowing,  the government's fiscal and monetary policies, and the
          international balance of payments.

               Foreign  securities  often trade with less  frequency and in less
          volume than domestic  securities  and  therefore  may exhibit  greater
          price  volatility.  Additional  costs associated with an investment in
          foreign  securities  may include  higher  custodian fees than apply to
          domestic  custodial  arrangements,  and  transaction  costs of foreign
          currency  conversions.  Changes  in foreign  exchange  rates also will
          affect the value of  securities  denominated  or quoted in  currencies
          other than the U.S. dollar.

               Foreign  markets also have  different  clearance  and  settlement
          procedures,  and  in  certain  markets  there  have  been  times  when
          settlements  have  been  unable  to  keep  pace  with  the  volume  of
          securities   transactions,   making  it   difficult  to  conduct  such
          transactions.  Such delays in  settlement  could  result in  temporary
          periods when a portion of the assets of a Series is uninvested  and no
          return is earned  thereon.  The inability of a Series to make intended
          security purchases due to settlement  problems could cause a Series to
          miss  attractive  investment  opportunities.  Inability  to dispose of
          portfolio securities due to settlement problems could result either in
          losses  to a  Series  due  to  subsequent  declines  in  value  of the
          portfolio  securities,  or, if a Series has entered into a contract to
          sell  the  securities,  could  result  in  possible  liability  to the
          purchaser.  In addition,  with respect to certain  foreign  countries,
          there is the possibility of  expropriation  or confiscatory  taxation,
          political or social  instability,  or  diplomatic  developments  which
          could  affect a  Series'  investments  in those  countries.  Moreover,
          individual  foreign economies may differ favorably or unfavorably from
          the U.S. economy in such respects as growth of gross national product,
          rate of inflation, capital reinvestment, resource self-sufficiency and
          balance of payments position.

               With respect to all Series except AMT  International  Investments
          and AMT Liquid Asset Investments,  in order to limit the risk inherent
          in investing in foreign- currency-denominated  securities, each Series
          may not purchase any such  security if after such  purchase  more than
          10% of its  total  assets  (taken at market  value)  (except  25% with
          respect  to  AMT  Limited   Maturity   Bond  and   Government   Income
          Investments)  would  be  invested  in  such  securities.  Within  such
          limitation,  however,  a Series is not restricted in the amount it may
          invest in securities denominated in any one foreign currency.
   
               Variable  or  Floating   Rate   Securities.   (AMT  Liquid  Asset
          Investments,  AMT Limited  Maturity Bond  Investments,  AMT Government
          Income  Investments,  and AMT  Balanced  Investments).  Variable  rate
          securities  provide for  automatic  adjustment of the interest rate at
          fixed intervals (e.g.,  daily,  monthly,  or semi-annually);  floating
          rate securities provide for automatic  adjustment of the interest rate
          whenever some specified interest rate index changes. The interest rate
          on variable and floating rate securities (collectively, "Variable Rate
          Securities")  ordinarily  is  determined  by reference to a particular
          bank's prime rate,  the 90-day U.S.  Treasury  Bill rate,  the rate of
          return  on  commercial  paper or bank  Cds,  an  index  of  short-term
          tax-exempt  rates or some other objective  measure.  The Variable Rate
          Securities in which each Series invests  frequently  permit the holder
          to demand payment of the securities' principal and accrued interest at
          any time or at specified  intervals not exceeding one year. The demand
          feature usually is backed by a credit  instrument (e.g., a bank letter
          of credit) from a creditworthy  issuer and sometimes by insurance from
          a  creditworthy  insurer.  Without  these  credit  enhancements,   the
          Variable  Rate  Securities  might  not  meet  the  quality   standards
          applicable to  obligations  purchased by the Series.  Accordingly,  in
          purchasing  these  securities,  each Series  relies  primarily  on the
          creditworthiness  of the credit  instrument  issuer or the insurer.  A
          Series will not invest more than 5% of its total assets in  securities
          backed by credit  instruments from any one issuer or by insurance from
          any one insurer  (excluding  securities that do not rely on the credit
          instrument  or insurance for their  rating,  i.e.,  stand on their own
          credit).
    
               A Series can also buy fixed rate securities accompanied by demand
          features or put options, permitting the Series to sell the security to
          the issuer or third party at a specified  price.  A Series may rely on
          the   creditworthiness   of  issuers  of  puts  in  purchasing   these
          securities.

               In calculating its maturity or duration, each Series is permitted
          to treat certain  variable and floating rate securities as maturing on
          a date  prior  to the date on which  principal  is due to be paid.  In
          applying such maturity  shortening devices,  N&B Management  considers
          whether the  interest  rate reset is expected to cause the security to
          trade at approximately its par value.

               Mortgage-Backed  Securities.  (AMT Liquid Asset Investments,  AMT
          Limited Maturity Bond Investments,  AMT Government Income  Investments
          and AMT Balanced  Investments).  Mortgage-backed  securities represent
          direct or  indirect  participations  in, or are secured by and payable
          from,  pools of mortgage loans.  They may be issued or guaranteed by a
          U.S.  Government  agency or  instrumentality  (though not  necessarily
          backed by the full faith and credit of the United States), such as the
          Government  National  Mortgage  Association   ("GNMA"),   the  Federal
          National  Mortgage  Association  ("FNMA"),  and the Federal  Home Loan
          Mortgage Corporation ("FHLMC"), or may be issued by private issuers.

               Mortgage-backed   securities   may  be  issued  in  the  form  of
          collateralized mortgage obligations ("CMOs") or mortgage-backed bonds.
          CMOs are obligations fully collateralized  directly or indirectly by a
          pool of  mortgages  on which  payments of  principal  and interest are
          passed through to the holders of the CMOs, although not necessarily on
          a pro  rata  basis,  on  the  same  schedule  as  they  are  received.
          Mortgage-backed  bonds are  general  obligations  of the issuer  fully
          collateralized  directly or  indirectly  by a pool of  mortgages.  The
          mortgages serve as collateral for the issuer's payment  obligations on
          the bonds,  but interest and  principal  payments on the mortgages are
          not  passed   through   either   directly  (as  with   mortgage-backed
          "pass-through"  securities  issued or  guaranteed  by U.S.  Government
          agencies or  instrumentalities) or on a modified basis (as with CMOs).
          Accordingly,  a  change  in the  rate of  prepayments  on the  pool of
          mortgages could change the effective maturity of a CMO but not that of
          a  mortgage-backed  bond (although,  like many bonds,  mortgage-backed
          bonds may be callable by the issuer prior to maturity).

               Governmental, government-related, and private entities may create
          mortgage    loan   pools   to   back   mortgage    pass-through    and
          mortgage-collateralized  investments  in addition  to those  described
          above.  Commercial  banks,  savings  institutions,   private  mortgage
          insurance  companies,  mortgage  bankers,  and other secondary  market
          issuers,  including  securities  broker-dealers  and  special  purpose
          entities (which generally are affiliates of the foregoing  established
          to  issue  such  securities),   also  create   pass-through  pools  of
          residential  mortgage  loans.  In  addition,  such  issuers may be the
          originators and/or servicers of the underlying  mortgage loans as well
          as the guarantors of the mortgage-backed securities.  Pools created by
          non-governmental  issuers  generally  offer a higher  rate of interest
          than government and government-related pools because of the absence of
          direct or indirect government or agency guarantees.  Timely payment of
          interest  and  principal  of these pools may be  supported  by various
          forms of insurance or guarantees,  including  individual loan,  title,
          pool, and hazard insurance,  and letters of credit.  The insurance and
          guarantees are issued by governmental entities,  private insurers, and
          the mortgage  poolers.  Such insurance and guarantees,  as well as the
          creditworthiness   of  the  issuers  thereof  will  be  considered  in
          determining  whether  a  mortgage-backed   security  meets  a  Series'
          investment  quality  standards.  There  can be no  assurance  that the
          private  insurers or guarantors can meet their  obligations  under the
          insurance policies or guarantee arrangements.

               A Series may buy mortgage-backed  securities without insurance or
          guarantees,  if N&B Management determines that the securities meet the
          Series' quality standards. A Series will not purchase  mortgage-backed
          securities or any other assets that, in N&B Management's  opinion, are
          illiquid  if, as a result,  more than 10% of the value of the  Series'
          net assets will be illiquid.  N&B Management  will,  consistent with a
          Series'  objective,  policies and limitations,  and quality standards,
          consider making investments in new types of mortgage-backed securities
          as such securities are developed and offered to investors.
   
               Because many mortgages are repaid early,  the actual  maturity of
          many  mortgage-related  securities  is shorter than their stated final
          maturity.  In calculating its maturity or duration, a Series may apply
          certain  industry  conventions  regarding  the maturity or duration of
          mortgage-backed  instruments.  A change in market  interest rates will
          affect  the  rate  at  which  homeowners  prepay  or  refinance  their
          mortgages and,  consequently,  will change the effective maturities of
          most mortgage-related securities.
    
               Asset-Backed  Securities.  (AMT  Liquid  Asset  Investments,  AMT
          Limited Maturity Bond Investments,  AMT Government Income Investments,
          and AMT Balanced Investments).  These Series may purchase asset-backed
          securities,   including  commercial  paper.   Asset-backed  securities
          represent direct or indirect  participations in, or are secured by and
          payable from, pools of assets such as motor vehicle  installment sales
          contracts, installment loan contracts, leases of various types of real
          and personal  property,  and receivables from revolving credit (credit
          card)  agreements.  These  assets are  securitized  through the use of
          trusts and special purpose corporations.  Payments or distributions of
          principal and interest on asset-backed  securities may be supported by
          credit enhancements, such as various forms of cash collateral accounts
          or letters of credit. Like mortgage-related  securities,  asset-backed
          securities  are  subject  to the risk of  prepayment.  The  risk  that
          recovery on repossessed  collateral might be unavailable or inadequate
          to support payments on asset-backed  securities,  however,  is greater
          than is the case for mortgage-backed securities.

               Certificates  for  Automobile  Receivables  ("CARS  ")  represent
          undivided  fractional  interests in a trust whose assets  consist of a
          pool of motor vehicle retail  installment sales contracts and security
          interests  in  the  vehicles  securing  the  contracts.   Payments  of
          principal  and  interest  on  CARS  are  "passed-through"  monthly  to
          certificate  holders and are  guaranteed up to specified  amounts by a
          letter of credit issued by a financial  institution  unaffiliated with
          the trustee or originator of the trust.  Underlying  installment sales
          contracts  are  subject to  prepayment,  which may reduce the  overall
          return to certificate holders. Certificate holders also may experience
          delays  in  payment  or  losses  on CARS if the  full  amounts  due on
          underlying  installment  sales contracts are not realized by the trust
          because of unanticipated  legal or  administrative  costs of enforcing
          the  contracts,  or because of  depreciation,  damage,  or loss of the
          vehicles securing the contracts, or other factors.

               Credit card receivable  securities are backed by receivables from
          revolving  credit card  agreements  ("Accounts").  Credit  balances on
          Accounts are  generally  paid down more  rapidly  than are  automobile
          contracts.  Most  of the  credit  card  receivable  securities  issued
          publicly  to date have  been  pass-through  certificates.  In order to
          lengthen the maturity of credit card receivable securities,  most such
          securities  provide  for a fixed  period  during  which only  interest
          payments on the underlying Accounts are passed through to the security
          holder and  principal  payments  received on the  Accounts are used to
          fund the transfer to the pool of assets  supporting  the securities of
          additional  credit card charges  made on the  Accounts.  Usually,  the
          initial  fixed period also may be  shortened  upon the  occurrence  of
          specified events that signal a potential  deterioration in the quality
          of the assets backing the security, such as the imposition of a cap on
          interest  rates.  The  ability  of the issuer to extend the life of an
          issue  of  credit  card  receivable  securities  thus  depends  on the
          continued generation of additional principal amounts in the underlying
          Accounts   and   the   non-occurrence   of   specified   events.   The
          nondeductibility  of consumer  interest,  as well as  competitive  and
          general economic factors, could adversely affect the rate at which new
          receivables  are  created in an  Account  and  conveyed  to an issuer,
          shortening the expected  weighted average life of the related security
          and reducing its yield. An acceleration in cardholders'  payment rates
          or any other event that  shortens the period  during which  additional
          credit card  charges on an Account may be  transferred  to the pool of
          assets  supporting the related security could have a similar effect on
          its weighted average life and yield.

               Credit  cardholders  are entitled to the  protection of state and
          federal consumer credit laws, many of which give a holder the right to
          set off certain  amounts  against  balances  owed on the credit  card,
          thereby  reducing amounts paid on Accounts.  In addition,  unlike most
          other asset-backed  securities,  Accounts are unsecured obligations of
          the cardholders.

               Dollar  Rolls.  (AMT  Limited  Maturity  Bond  Investments,   AMT
          Government  Income  Investments,  and  AMT  Balanced  Investments).  A
          "dollar roll" involves the sale by a Series of securities for delivery
          in the  current  month  and the  Series'  simultaneously  agreeing  to
          repurchase  substantially similar (same type and coupon) securities on
          a specified  future date from the same  party.  A "covered  roll" is a
          specific  type of dollar  roll for which there is an  offsetting  cash
          position or a cash  equivalent  security  position  that matures on or
          before the forward  settlement  date of the dollar  roll  transaction.
          These  techniques  are  considered  borrowings  for  purposes  of each
          Series'  investment  policies and limitations  concerning  borrowings.
          There is a risk that the  contra-party  will be unable or unwilling to
          complete the transactions as scheduled,  which may result in losses to
          each Series.

               Forward  Commitments  and  When-Issued  Securities.  (All  Series
          except  AMT  Liquid  Asset  Investments).  Each  Series  may  purchase
          securities  (including,  with  respect to AMT Limited  Maturity  Bond,
          Government Income and Balanced Investments, mortgage-backed securities
          such as GNMA,  FHMA, and FHLMC  certificates) on a when- issued basis,
          that  is,  by  committing  to  purchase   securities   (to  secure  an
          advantageous  price  and  yield  at the  time of the  commitment)  and
          completing  the  purchase by making  payment  against  delivery of the
          securities  at  a  future  date.  AMT  International  Investments  may
          purchase  securities  on a  when-issued  basis  or  purchase  or  sell
          securities on a forward commitment basis. These transactions involve a
          commitment by a Series to purchase or sell securities at a future date
          (ordinarily  one or two  months  later).  The price of the  underlying
          securities (usually expressed in terms of yield) and the date when the
          securities  will be delivered and paid for (the  settlement  date) are
          fixed at the time the transaction is negotiated. When-issued purchases
          and forward commitment  transactions are negotiated  directly with the
          other party, and such commitments are not traded on exchanges.

               When-issued purchases and forward commitment  transactions enable
          a Series to "lock in" what the adviser  believes  to be an  attractive
          price  or  yield  on a  particular  security  for a  period  of  time,
          regardless  of future  changes in interest  rates.  For  instance,  in
          periods of rising  interest rates and falling  prices,  a Series might
          sell  securities  it owns on a forward  commitment  basis to limit its
          exposure to falling prices.  In periods of falling  interest rates and
          rising prices,  a Series might purchase a security on a when-issued or
          forward  commitment  basis and sell a similar  security to settle such
          purchase, thereby obtaining the benefit of currently higher yields.

               The value of  securities  purchased on a  when-issued  or forward
          commitment  basis and any subsequent  fluctuations  in their value are
          reflected in the  computation of a Series' net asset value starting on
          the date of the  agreement to purchase the  securities.  A Series does
          not earn interest on the securities it has committed to purchase until
          they are paid for and delivered on the settlement  date. When a Series
          makes a forward commitment to sell securities it owns, the proceeds to
          be  received  upon  settlement  are  included  in  a  Series'  assets.
          Fluctuations in the market value of the underlying  securities are not
          reflected in a Series' NAV as long as the  commitment  to sell remains
          in effect.  Settlement of when-issued purchases and forward commitment
          transactions generally takes place within two months after the date of
          the  transactions,  but a Series  may  agree  to a  longer  settlement
          period.

               A Series  will  purchase  securities  on a  when-issued  basis or
          purchase or sell  securities on a forward  commitment  basis only with
          the intention of completing the transaction and actually purchasing or
          selling the securities.  If deemed advisable as a matter of investment
          strategy, however, a Series may dispose of or renegotiate a commitment
          after it has been entered  into. A Series also may sell  securities it
          has committed to purchase before those securities are delivered to the
          Series on the settlement  date. A Series may realize a capital gain or
          loss in connection with these transactions.

               When a Series  purchases  securities on a when-issued  basis,  it
          maintains,  in a segregated account with its custodian,  until payment
          is made, cash, U.S. government securities, or other liquid, high-grade
          debt securities  having an aggregate  market value equal to the amount
          of its purchase  commitment.  In the case of a forward  commitment  to
          sell  portfolio  securities,  the  custodian  will hold the  portfolio
          securities  themselves in a segregated account while the commitment is
          outstanding.  These  procedures  are  designed to ensure that a Series
          will maintain  sufficient assets at all times to cover its obligations
          under when-issued purchases and forward commitments.

          Investments  may write or purchase put and call options on securities.
          Each of AMT Partners and AMT Growth  Investments may write or purchase
          covered call options on  securities it owns valued at up to 10% of its
          net assets.  Generally,  the purpose of writing and  purchasing  these
          options is to reduce the effect of the securities' price  fluctuations
          that effect a Portfolio's NAV. AMT Limited  Maturity Bond,  Government
          Income,  and Balanced  Investments may also write covered call options
          to earn premium income.
    
               AMT International Investments may write call options and purchase
          put options on securities  in order to hedge (i.e.,  write or purchase
          options to reduce the effect of price  fluctuations of securities held
          by the Series that affect the  Portfolio's  NAV).  The Series may also
          purchase or write put options, purchase call options and write covered
          call options in an attempt to enhance income.

               The obligation under any option terminates upon expiration of the
          option or at an earlier  time,  when the writer  offsets the option by
          entering into a "closing  purchase  transaction" to purchase an option
          of the same series. If an option is purchased by a Series and is never
          exercised, the Series will lose the entire amount of the premium paid.

               A Series will  receive a premium for writing a put option,  which
          will  obligate  the Series to acquire a certain  security at a certain
          price at any time until a certain date if the  purchaser of the option
          decides  to sell  such  security.  The  writer  of the  option  may be
          obligated to purchase the security at more than its current value.

               When a Series  purchases a put  option,  it pays a premium to the
          writer for the right to sell a security  to the writer for a specified
          amount at any time until a certain date. A Series would purchase a put
          option in order to  protect  itself  against a decline  in the  market
          value of a security it owns.

               When a Series  writes a call  option,  it is  obligated to sell a
          security to a purchaser at a specified price at any time the purchaser
          requests,  until a certain date, for a premium. Each Series intends to
          write only  "covered"  call options on  securities it owns. So long as
          the obligation of the writer of the call option continues,  the writer
          may be  assigned  an  exercise  notice,  requiring  it to deliver  the
          underlying  security against payment of the exercise price. The writer
          may be obligated to deliver  securities  underlying  an option at less
          than the market price  thereby  giving up any  additional  gain on the
          security.

               When a Series purchases a call option,  it pays a premium for the
          right to  purchase a security  from the  writer at a  specified  price
          until a specified  date.  A call option would be purchased by a Series
          in order to protect against an increase in the price of the securities
          it intends to purchase or to offset a previously written call option.

               Portfolio securities on which call and put options may be written
          and  purchased  by a  Series  are  purchased  solely  on the  basis of
          investment  considerations  consistent  with  the  Series'  investment
          objective.  The  writing of  covered  call  options is a  conservative
          investment  technique  believed to involve  relatively little risk (in
          contrast to the writing of "naked" or uncovered call options,  which a
          Series  will not do),  but is capable  of  enhancing  a Series'  total
          return.  When writing a covered call option,  a Series,  in return for
          the premium, gives up the opportunity for profit from a price increase
          in the underlying  security above the exercise  price,  but conversely
          retains  the risk of loss  should the price of the  security  decline.
          When writing a put option, a Series, in return for the premium,  takes
          the risk that it must purchase the underlying  security at an exercise
          price,  which  may be  more  than  the  current  market  price  of the
          security.  If a call or put option that a Series has  written  expires
          unexercised,  the  Series  will  realize  a gain in the  amount of the
          premium;  however,  in the  case of a call  option,  that  gain may be
          offset by a decline in the  market  value of the  underlying  security
          during the option period. If the call or put option is exercised,  the
          Series  will  realize a gain or loss from the sale or  purchase of the
          underlying security.

               Securities  options  are  traded  both  on  exchanges  and in the
          over-the-counter ("OTC") market. Exchange-traded options are issued by
          a clearing  organization  affiliated  with the  exchange  on which the
          option is  listed;  the  clearing  organization  in effect  guarantees
          completion of every exchange-traded  option. In contrast,  OTC options
          are contracts between a Series and its counter-party  with no clearing
          organization guarantee.  Thus, when a Series sells or purchases an OTC
          option,  it generally  will be able to "close out" the option prior to
          its expiration only by entering into a "closing purchase  transaction"
          with the  dealer to whom or from whom the  Series  originally  sold or
          purchased the option. There can be no assurance that a Series would be
          able to  liquidate  an OTC  option  at any time  prior to  expiration.
          Unless a Series is able to effect a closing purchase  transaction in a
          covered  OTC  call  option  it has  written,  it  will  not be able to
          liquidate  securities  used as cover  until the  option  expires or is
          exercised  or  different  cover is  substituted.  In the  event of the
          counter-party's  insolvency,  a Series may be unable to liquidate  its
          option position and the associated cover. N&B Management  monitors the
          creditworthiness  of  dealers  with  which a Series  may engage in OTC
          options, and will limit a Series'  counterparties in such transactions
          to dealers  with a net worth of at least $20  million as  reported  in
          their latest financial statements.

               The assets used as cover (and held in a  segregated  account) for
          OTC options  sold or written by a Series will be  considered  illiquid
          for purposes of the  non-fundamental  policies and  limitations of the
          Series unless the OTC options are sold to qualified  dealers who agree
          that the Series may  repurchase  any OTC option it writes at a maximum
          price to be calculated by a formula set forth in the option agreement.
          The cover for an OTC call  option  written  subject to this  procedure
          will be  considered  illiquid  only to the  extent  that  the  maximum
          repurchase  price under the formula exceeds the intrinsic value of the
          option.

               The  premium  received  (or paid) by a Series  when it writes (or
          purchases)  a call or put  option is the amount at which the option is
          currently  traded  on  the  applicable  exchange,  less  (or  plus)  a
          commission.  The premium may reflect,  among other things, the current
          market  price of the  underlying  security,  the  relationship  of the
          exercise price to the market price, the historical price volatility of
          the underlying security,  the length of the option period, the general
          supply  of and  demand  for  credit,  and the  general  interest  rate
          environment.  The  premium  received by a Series for writing a covered
          call or put option is recorded as a liability on the Series' statement
          of assets and  liabilities.  This  liability is adjusted  daily to the
          option's  current  market  value,  which  is the  sales  price  on the
          option's  last trade on that day before  the time the  Series'  NAV is
          computed  or, in the  absence of any trades  thereof on that day,  the
          mean between the bid and ask prices as of that time.

               Each Series pays the brokerage  commissions  in  connection  with
          purchasing  or  writing  options,  including  those  used to close out
          existing positions.  These brokerage  commissions  normally are higher
          than those applicable to purchases and sales of portfolio securities.

               Closing transactions are effected in order to realize a profit on
          an outstanding  option,  to prevent an underlying  security from being
          called,  or to permit the sale or the put of the underlying  security.
          Furthermore, effecting a closing transaction permits a Series to write
          another call option on the underlying security with either a different
          exercise price or expiration date or both. If a Series desires to sell
          a particular  security on which it has written a call option (or if it
          desires to protect  itself  against  having to  purchase a security on
          which it has written a put  option),  it will seek to effect a closing
          transaction prior to, or concurrently  with, the sale (or purchase) of
          the security.  There is, of course, no assurance that a Series will be
          able to effect closing  transactions at favorable  prices. If a Series
          cannot  enter into such a  transaction,  it may be  required to hold a
          security that it might  otherwise  have sold,  (or purchase a security
          that it  would  not have  otherwise  bought),  in which  case it would
          continue to be subject to market risk on the security.

               Options  normally  have  expiration  dates between three and nine
          months  from the  date  written.  AMT  International  Investments  may
          purchase  both  European-style  options  and  American-style  options.
          European-style options are only exercisable immediately prior to their
          expiration.  American-style  options, in contrast,  are exercisable at
          any time prior to their  expiration  date.  The  exercise  price of an
          option may be below,  equal to, or above the current  market  value of
          the underlying  security at the time the option is written.  From time
          to time, a Series may purchase an underlying  security for delivery in
          accordance  with an exercise  notice of a call option  assigned to it,
          rather than  delivering  the  security  from its  portfolio.  In those
          cases, additional brokerage commissions are incurred.

               A Series  will  realize a profit or loss from a closing  purchase
          transaction  if the cost of the  transaction  is less or more than the
          premium received from writing the call or put option. However, because
          increases  in the  market  price of a call  option  generally  reflect
          increases in the market  price of the  underlying  security,  any loss
          resulting  from the repurchase of a call option is likely to be offset
          in whole or in part by appreciation  of the underlying  security owned
          by a Series.

               Put and Call Options on Securities  Indices.  (AMT  International
          Investments).  AMT International Investments may write or purchase put
          and call  options on  securities  indices  for the  purpose of hedging
          against the risk of unfavorable  price movements  adversely  affecting
          the value of the Series'  securities or securities  the Series intends
          to buy.  However,  the  Series  currently  does not expect to invest a
          substantial portion of its assets in securities index options.  Unlike
          a securities  option,  which gives the holder the right to purchase or
          sell a  specified  security  at a  specified  price,  an  option  on a
          securities  index  gives  the  holder  the  right  to  receive  a cash
          "exercise  settlement  amount" equal to (i) the difference between the
          exercise  price  of  the  option  and  the  value  of  the  underlying
          securities  index  on the  exercise  date  multiplied  by (ii) a fixed
          "index multiplier."

               A securities  index  fluctuates with changes in the market values
          of the securities included in the index.  Options on stock indexes are
          currently traded on the Chicago Board Options Exchange,  the NYSE, the
          AmEx and foreign exchanges.

               The Series may purchase put options in order to hedge  against an
          anticipated  decline in securities  market prices that might adversely
          affect the value of the Series'  portfolio  securities.  If the Series
          purchases  a put  option  on a  securities  index,  the  amount of the
          payment it would  receive upon  exercising  the option would depend on
          the extent of any decline in the level of the  securities  index below
          the exercise  price.  Such payments  would tend to offset a decline in
          the value of the Series' portfolio  securities.  However, if the level
          of the securities index increases and remains above the exercise price
          while the put option is  outstanding,  the Series  will not be able to
          exercise the option profitably and will lose the amount of the premium
          and any  transaction  costs.  Such loss may be partially  offset by an
          increase in the value of the Series's portfolio securities.

               The Series may  purchase  call options on  securities  indices in
          order to participate in an anticipated  increase in securities  market
          prices.  If the Series purchases a call option on a securities  index,
          the  amount of the  payment it  receives  upon  exercising  the option
          depends on the extent of any  increase in the level of the  securities
          index above the exercise price. Such payments would, in effect,  allow
          the Series to benefit from securities market  appreciation even though
          it may not  have  had  sufficient  cash  to  purchase  the  underlying
          securities.  Such  payments may also offset  increases in the price of
          securities that the Series intends to purchase. If, however, the level
          of the securities  index declines and remains below the exercise price
          while the call option is  outstanding,  the Series will not be able to
          exercise the option profitably and will lose the amount of the premium
          and  transaction  costs.  Such  loss  may  be  partially  offset  by a
          reduction  in the price the Series pays to buy  additional  securities
          for its portfolio.

               The Series may write  securities  index options in order to close
          out  positions in securities  index  options  which it has  purchased.
          These  closing  sale  transactions  enable the Series  immediately  to
          realize  gains or  minimize  losses on its options  positions.  If the
          Series is unable to effect a closing sale  transaction with respect to
          options that it has  purchased,  it would have to exercise the options
          in order to realize  any profit and may incur  transaction  costs upon
          the purchase or sale of underlying securities.

               The hours of trading  for  options  may not  conform to the hours
          during which the underlying  securities are traded. To the extent that
          the  options  markets  close  before the  markets  for the  underlying
          securities, significant price and rate movements can take place in the
          underlying markets that cannot be reflected in the options markets.

               The  effectiveness  of hedging through the purchase of securities
          index options will depend upon the extent to which price  movements in
          the portion of the securities  portfolio  being hedged  correlate with
          price movements in the selected securities index.  Perfect correlation
          is not possible  because the securities  held or to be acquired by the
          Series  will not  exactly  match  the  composition  of the  securities
          indices on which options are available.  In addition,  the purchase of
          securities  index  options  involves  the risk  that the  premium  and
          transaction  costs paid by the Series in  purchasing an option will be
          lost  as  a  result  of  unanticipated  movements  in  prices  of  the
          securities  comprising  the  securities  index on which the  option is
          based.

               Other Risks of Options Transactions. All securities index options
          purchased by AMT  International  Investments will be listed and traded
          on an exchange.  There is no assurance that a liquid  secondary market
          on  a  domestic  or  foreign  options  exchange  will  exist  for  any
          particular  exchange-traded option, or at any particular time, and for
          some  options no  secondary  market on an  exchange or  elsewhere  may
          exist.  If  the  Series  is  unable  to  effect  a  closing   purchase
          transaction  with respect to covered  options it has written,  it will
          not be able to sell the  underlying  securities  or  dispose of assets
          held  in  a  segregated  account  until  the  options  expire  or  are
          exercised.  AMT  International  Investments may purchase and sell both
          options  that are traded on U.S.  and  foreign  exchanges  and certain
          options traded in the OTC market in transactions  with  broker-dealers
          who make markets in such options.

               Reasons  for the  absence  of a  liquid  secondary  market  on an
          exchange include the following: (i) there may be insufficient interest
          in trading certain  options;  (ii)  restrictions  may be imposed by an
          exchange  on opening  transactions  or closing  transactions  or both;
          (iii) trading halts,  suspensions or other restrictions may be imposed
          with respect to particular  classes or series of options or underlying
          securities;  (iv) unusual or  unforeseen  circumstances  may interrupt
          normal operations on an exchange; (v) the facilities of an exchange or
          its clearing  organization  may not at all times be adequate to handle
          current  trading  volume;  or (vi) one or more  exchanges  could,  for
          economic or other reasons,  decide or be compelled at some future date
          to discontinue the trading of options (or a particular class or series
          of options),  in which event the secondary market on that exchange (or
          in that class or series of  options)  would  cease to exist,  although
          outstanding  options  on that  exchange  that had been  issued  by the
          clearing  organization  as a result of trades on that  exchange  would
          continue to be exercisable in accordance with their terms.

               The  writing  and  purchase  of options  is a highly  specialized
          activity which involves investment techniques and risks different from
          those associated with ordinary portfolio securities transactions.  The
          writing of options on securities involves a risk that a portfolio will
          be  required  to sell or  purchase  such  securities  at a price  less
          favorable  than the current  market price and will lose the benefit of
          appreciation or depreciation in the market price of such securities.

               The  Series  would  incur  brokerage  commissions  or  spreads in
          connection with its options  transactions as well as for purchases and
          sales of underlying  securities.  Brokerage  commissions  from options
          transactions  are  generally  higher  than  for  portfolio  securities
          transactions.  The writing of options  could  result in a  significant
          increase in the Series' turnover rate.

               Indexed Securities.  (AMT Limited Maturity Bond Investments,  AMT
          Government Income Investments,  AMT International Investments, and AMT
          Balanced Investments). These Series may invest in securities linked to
          foreign  currencies,  interest rates,  commodities,  indices, or other
          financial indicators ("indexed  securities").  Most indexed securities
          are short- to intermediate-term fixed income securities whose value at
          maturity or interest  rate rises or falls  according  to the change in
          one or more specified underlying  instruments.  Indexed securities may
          be positively or negatively indexed (i.e., their value may increase or
          decrease if the underlying instrument appreciates) and may have return
          characteristics  similar  to  direct  investments  in  the  underlying
          instrument or to one or more options  thereon.  However,  some indexed
          securities are more volatile than the underlying instrument itself.

               Futures  Contracts  and  Options  Thereon.   (AMT   International
          Investments,  AMT Limited  Maturity Bond  Investments,  AMT Government
          Income Investments,  and AMT Balanced Investments).  AMT International
          Investments may enter into futures  contracts for the purchase or sale
          of individual  securities and futures contracts on securities  indices
          which are traded on exchanges  licensed and regulated by the Commodity
          Futures Trading Commission  ("CFTC") or on foreign exchanges.  Trading
          on  foreign  exchanges  is subject  to the legal  requirements  of the
          jurisdiction  in which the  exchange  is located and the rules of such
          foreign exchange. AMT International  Investments may purchase and sell
          futures  for bona fide  hedging  purposes  and non-  hedging  purposes
          (i.e.,  in an effort to enhance  income) as defined in  regulations of
          the CFTC.
   
               AMT  Limited  Maturity  Bond,  Government  Income,  and  Balanced
          Investments may purchase and sell interest-rate  futures contracts and
          options  thereon.  These  Series  engage in interest  rate futures and
          options  transactions  in an  attempt  to  hedge  against  changes  in
          securities  prices  resulting  from  expected  changes  in  prevailing
          interest  rates,  and they  engage in  foreign  currency  futures  and
          options  transactions in an attempt to hedge against  expected changes
          in prevailing currency exchange rates. Because the futures markets may
          be more liquid  than the cash  markets,  the use of futures  permits a
          Series  to  enhance  portfolio  liquidity  and  maintain  a  defensive
          position without having to sell portfolio securities.  These Series do
          not  engage  in   transactions  in  futures  or  options  thereon  for
          speculation;  they view  investment in (1)  interest-rate  futures and
          options thereon as a maturity or duration  management  device and/or a
          device to reduce risk and preserve total return in an adverse interest
          rate  environment and (2) foreign currency futures and options thereon
          as a means of  establishing  more  definitely the effective  return on
          securities  denominated in foreign  currencies  held or intended to be
          acquired by them.
    
               A  futures  contract  on  a  security  is a  binding  contractual
          commitment which, if held to maturity, will result in an obligation to
          make or accept delivery of securities having a standardized face value
          and rate of return during a particular month. By purchasing futures on
          securities,  a Series will legally  obligate itself to accept delivery
          of the  underlying  security and to pay the agreed  price.  By selling
          futures on securities, the Series will legally obligate itself to make
          delivery of the security and receive payment of the agreed price.

               Open  futures  positions  on  securities  are  valued at the most
          recent settlement  price,  unless such price does not reflect the fair
          value of the contract, in which case the position will be valued by or
          under the direction of the Trustees of Managers Trust.

               Futures contracts on securities are not normally held to maturity
          but are instead liquidated  through offsetting  transactions which may
          result in a profit or loss.  While  futures  contracts  on  securities
          entered  into by a Series will usually be  liquidated  in this manner,
          the  Series  may  instead  make or  take  delivery  of the  underlying
          securities whenever it appears economically  advantageous for it to do
          so. A  clearing  corporation  associated  with the  exchange  on which
          futures on securities  are traded assumes  responsibility  for closing
          out contracts and  guarantees  that, if a contract is still open,  the
          sale or purchase of  securities  will be performed  on the  settlement
          date.
   
               Similarly,  a securities  index futures contract does not require
          the physical  delivery of securities,  but merely provides for profits
          and losses  resulting from changes in the market value of the contract
          to be  credited  or  debited at the close of each  trading  day to the
          respective accounts of the parties to the contract.  On the contract's
          expiration  date,  a final  cash  settlement  occurs  and the  futures
          positions  are simply  closed  out.  Changes in the market  value of a
          particular  securities  index futures  contract reflect changes in the
          specified  index of the  securities  on which the futures  contract is
          based.
    
               A Series  sells  futures  contracts in order to offset a possible
          decline in the value of its  securities.  When a futures  contract  is
          sold by a Series, the value of the contract will tend to rise when the
          value of the Series'  securities  declines  and will tend to fall when
          the value of such  securities  increases.  A Series  purchases  future
          contracts in order to fix what is believed to be a favorable price for
          securities  a Series  intends to  purchase.  If a futures  contract is
          purchased by a Series,  the value of the contract  will tend to change
          together with changes in the value of such securities.

               A  Series  may also  purchase  put and call  options  on  futures
          contracts for bona fide hedging and, with respect to AMT International
          Investments,  non-hedging purposes. A put option purchased by a Series
          would  give it the  right to  assume a  position  as the  seller  of a
          futures contract (assume a "short position").  A call option purchased
          by a Series  would  give it the  right to  assume  a  position  as the
          purchaser  of a  futures  contract  (assume  a "long  position").  The
          purchase of an option on a futures contract requires a Series to pay a
          premium.  In exchange for the premium,  a Series  becomes  entitled to
          exercise the benefits,  if any, provided by the futures contract,  but
          is not required to take any actions under the contract.  If the option
          cannot be  profitably  exercised  before it expires,  the Series' loss
          will be  limited  to the  amount of the  premium  and any  transaction
          costs.

               In  addition,  a Series may write  (sell) put and call options on
          futures  contracts  for bona fide  hedging  and,  with  respect to AMT
          International Investments,  non-hedging purposes. The writing of a put
          option on a futures contract generates a premium,  which may partially
          offset an increase in the price of securities that a Series intends to
          purchase.  However,  a Series becomes  obligated to purchase a futures
          contract,  which  may  have a value  lower  than the  exercise  price.
          Conversely,  the  writing  of a  call  option  on a  futures  contract
          generates a premium which may partially  offset a decline in the value
          of a Series'  assets.  By  writing  a call  option,  a Series  becomes
          obligated,  in exchange for the premium,  to sell a futures  contract,
          which may have a value higher than the exercise price.

               A Series may enter into closing purchase or sale  transactions in
          order to  terminate  a  futures  contract.  A Series  may close out an
          option which it has  purchased or written by selling or  purchasing an
          offsetting option of the same series.  There is no guarantee that such
          closing  transactions can be effected. A Series' ability to enter into
          closing  transactions  depends on the development and maintenance of a
          liquid market, which may not be available at all times.
   
               Although futures and options  transactions are intended to enable
          a Series to manage  interest rate,  stock market or currency  exchange
          risks,  unanticipated  changes in  interest  rates,  market  prices or
          currency  exchange rates could result in poorer  performance than if a
          Series had not entered into these transactions. Even if N&B Management
          correctly  predicts  interest  rate,  market  price or  currency  rate
          movements,  a hedge could be unsuccessful if changes in the value of a
          Series' futures position did not correspond to changes in the value of
          its  investments.  This lack of correlation  between a Series' futures
          and  securities  or currency  positions  may be caused by  differences
          between  the  futures  and  securities  or  currency   markets  or  by
          differences  between the  securities  underlying  the Series'  futures
          position and the securities held by or to be purchased for the Series.
          N&B Management  will attempt to minimize  these risks through  careful
          selection and monitoring of a Series'  futures and options  positions.
          The  ability to  predict  the  direction  of the  securities  markets,
          interest rates and currency  exchange rates involves skills  different
          from those used in selecting securities.
    
               The prices of futures  contracts depend primarily on the value or
          level of the  securities  or indices on which they are based.  Because
          there is a limited number of types of futures contracts,  it is likely
          that the standardized futures contracts available to a Series will not
          exactly match the  securities the Series wishes to hedge or intends to
          purchase,  and  consequently  will not provide a perfect hedge against
          all price  fluctuation.  To compensate  for  differences in historical
          volatility  between  positions  a  Series  wishes  to  hedge  and  the
          standardized  futures contracts available to it, a Series may purchase
          or sell  futures  contracts  with a greater  or lesser  value than the
          securities it wishes to hedge or intends to purchase.

               Foreign  Currency  Transactions.  (All  Series  except AMT Liquid
          Asset Investments). The Series may engage in foreign currency exchange
          transactions. Foreign currency exchange transactions will be conducted
          either on a spot (i.e., cash) basis at the spot rate prevailing in the
          foreign  currency  exchange  market,  or through entering into forward
          contracts to purchase or sell foreign currencies ("forward contracts")
          (in amounts not exceeding 5% of each Series' net assets,  with respect
          to AMT  Partners  and  Growth  Investments).  A Series  may enter into
          forward contracts in order to protect against uncertainty in the level
          of  future  foreign  currency   exchange  rates.   AMT   International
          Investments may also enter forward contracts for non-hedging purposes.
          A forward  contract  involves  an  obligation  to  purchase  or sell a
          specific  currency at a future date,  which may be any fixed number of
          days (usually less than one year) from the date of the contract agreed
          upon by the parties, at a price set at the time of the contract. These
          contracts  are  traded  in the  interbank  market  conducted  directly
          between traders (usually large commercial  banks) and their customers.
          A  forward  contract  generally  has no  deposit  requirement,  and no
          commissions  are  charged at any stage for  trades.  Although  foreign
          exchange dealers do not charge a fee for conversion, they do realize a
          profit based on the difference (the spread) between the price at which
          they are buying and selling various currencies.

               When a Series  enters into a contract for the purchase or sale of
          a security denominated in a foreign currency, it may wish to "lock in"
          the U.S.  dollar  price of the  security.  By entering  into a forward
          contract for the purchase or sale, for a fixed amount of U.S. dollars,
          of the amount of foreign currency involved in the underlying  security
          transactions,  a  Series  will be able to  protect  itself  against  a
          possible  loss.  Such loss would result from an adverse  change in the
          relationship  between the U.S. dollar and the foreign  currency during
          the period between the date on which the security is purchased or sold
          and the date on which payment is made or received.

               When  N&B  Management         believes  that  the  currency  of a
          particular  foreign  country may suffer a substantial  decline against
          the U.S. dollar, it may also enter into a forward contract to sell the
          amount  of  foreign  currency  for a fixed  amount  of  dollars  which
          approximates  the  value  of  some  or  all  of a  Series'  securities
          denominated  in such  foreign  currency.  The precise  matching of the
          forward contract amounts and the value of the securities involved will
          not generally be possible,  since the future value of such  securities
          denominated  in foreign  currencies  will change as a  consequence  of
          market movements in the value of those securities between the date the
          forward contract is entered into and the date it matures.
   
               A Series  may  also  engage  in  cross-hedging  by using  forward
          contracts in one currency to hedge against  fluctuations  in the value
          of securities denominated in a different currency, when N&B Management
          believes  that  there is a  pattern  of  correlation  between  the two
          currencies.  AMT International  Investments may also purchase and sell
          forward  contracts  for  non-hedging   purposes  when  N&B  Management
          anticipates that the foreign currency will appreciate or depreciate in
          value,  but  securities  in that  currency do not  present  attractive
          investment opportunities and are not held in the Series' portfolio.
    
               When a Series engages in forward  contracts for hedging purposes,
          it will not enter into forward  contracts to sell currency or maintain
          a net exposure to such contracts if their  consummation would obligate
          the Series to deliver an amount of foreign  currency  in excess of the
          value of the Series' portfolio  securities or other assets denominated
          in that  currency.  At the  consummation  of the forward  contract,  a
          Series may either make  delivery of the foreign  currency or terminate
          its  contractual  obligation  to deliver by  purchasing  an offsetting
          contract  obligating  it to purchase  the same amount of such  foreign
          currency  at the same  maturity  date.  If the Series  chooses to make
          delivery  of the foreign  currency,  it may be required to obtain such
          currency through the sale of portfolio securities  denominated in such
          currency or through conversion of other assets of the Series into such
          currency. If the Series engages in an offsetting transaction,  it will
          incur a gain or a loss to the  extent  that there has been a change in
          forward contract prices. Closing purchase transactions with respect to
          forward  contracts are usually made with the currency  trader who is a
          party to the original forward contract.

               The Series are not required to enter into such  transactions  and
          will not do so unless deemed appropriate by N&B Management        .

               Using  forward  contracts  to  protect  the  value  of a  Series'
          portfolio securities against a decline in the value of a currency does
          not eliminate fluctuations in the underlying prices of the securities.
          It simply establishes a rate of exchange which can be achieved at some
          future point in time.  The precise  projection of short-term  currency
          market  movements is not possible,  and short-term  hedging provides a
          means of  fixing  the  dollar  value of only a  portion  of a  Series'
          foreign assets.

               While a Series may enter  forward  contracts  to reduce  currency
          exchange rate risks,  transactions  in such contracts  involve certain
          other risks.  Thus, while a Series may benefit from such transactions,
          unanticipated  changes  in  currency  prices  may  result  in a poorer
          overall  performance  for the Series than if it had not engaged in any
          such  transactions.  Moreover,  there  may  be  imperfect  correlation
          between a Series'  portfolio  holdings of securities  denominated in a
          particular  currency and forward contracts entered into by the Series.
          Such  imperfect  correlation  may cause the Series to  sustain  losses
          which will  prevent  the Series  from  achieving  a complete  hedge or
          expose the Series to risk of foreign exchange loss.

               An issuer of fixed income securities purchased by a Series may be
          domiciled  in a country  other than the country in whose  currency the
          instrument is  denominated.  AMT  International  Investments  may also
          invest in debt  securities  denominated in the European  Currency Unit
          ("ECU"),  which is a "basket"  consisting of a specified amount in the
          currencies of certain of the member states of the European  Community.
          The specific amounts of currencies  comprising the ECU may be adjusted
          by the Council of  Ministers of the  European  Community  from time to
          time  to  reflect   changes  in  relative  values  of  the  underlying
          currencies.   In  addition,   the  Series  may  invest  in  securities
          denominated  in other  currency  "baskets."  The  market  for ECUs may
          become  illiquid  at  times of  uncertainty  or  rapid  change  in the
          European  currency  markets,  limiting the Series'  ability to prevent
          potential losses.

               A Series' activities in forward  contracts, currency futures
          contracts and related  options and  currency options (see  below)
          may  be limited  by the  requirements of  federal income  tax law
          applicable to its corresponding Portfolio  for qualification as a
          regulated  investment  company  ("RIC").    See  "Additional  Tax
          Information."
   
               Currency   Futures  and  Related  Options.   (AMT   International
          Investments,  AMT Limited  Maturity Bond  Investments,  AMT Government
          Income  Investments,  and AMT  Balanced  Investments).  Each of  these
          Series may enter into currency  futures  contracts and options on such
          futures  contracts  in  domestic  and foreign  markets.  Each of these
          Series may sell a currency  futures  contract or a call option,  or it
          may purchase a put option on such futures contract,  if N&B Management
          anticipates  that exchange rates for a particular  currency will fall.
          Such a transaction  will be used as a hedge (or, in the case of a sale
          of a call option,  a partial hedge) against a decrease in the value of
          a Series' securities  denominated in such currency.  If N&B Management
          anticipates  that  exchange  rates will rise,  a Series may purchase a
          currency  futures  contract  or a call  option to  protect  against an
          increase  in the  price  of  securities  which  are  denominated  in a
          particular  currency  and which the Series  intends to  purchase.  AMT
          International   Investments  may  also  purchase  a  currency  futures
          contract, or a call option thereon, for non- hedging purposes when N&B
          Management  anticipates that a particular  currency will appreciate in
          value,  but securities  denominated in that currency do not present an
          attractive  investment and are not included in the Series'  portfolio.
          Each Series will use these futures  contracts and related  options for
          hedging purposes and, with respect to AMT  International  Investments,
          for  non-hedging  purposes  as well  (i.e.,  in an effort  to  enhance
          income) as defined in CFTC regulations.
    
               The sale of a currency  futures contract creates an obligation by
          a Series,  as seller,  to deliver the amount of currency called for in
          the  contract at a specified  future time for a specified  price.  The
          purchase of a currency  futures  contract  creates an  obligation by a
          Series,  as purchaser,  to take delivery of an amount of currency at a
          specified  future time at a  specified  price.  Although  the terms of
          currency futures contracts specify actual delivery or receipt, in most
          instances  the  contracts  are closed out before the  settlement  date
          without the making or taking of delivery of the currency.  Closing out
          of a  currency  futures  contract  is  effected  by  entering  into an
          offsetting  purchase  or sale  transaction.  To close  out a  currency
          futures contract sold by a Series,  the Series may purchase a currency
          futures  contract for the same  aggregate  amount of currency and same
          delivery  date.  If the  price in the sale  exceeds  the  price in the
          offsetting  purchase,  the Series is immediately  paid the difference.
          Similarly,  to close out a currency  futures  contract  purchased by a
          Series,  the  Series  sells  a  currency  futures  contract.   If  the
          offsetting sale price exceeds the purchase price,  the Series realizes
          a gain.  Likewise,  if the  offsetting  sale  price  is less  than the
          purchase price, the Series realizes a loss.

               Unlike a currency futures contract, which requires the parties to
          buy and sell currency on a set date,  an option on a futures  contract
          entitles  its holder to decide on or before a future  date  whether to
          enter into such a  contract.  If the holder  decides not to enter into
          the contract,  the premium paid for the option is lost. For the holder
          of an option,  there are no daily payments of cash for  "variation" or
          "maintenance"  margin  payments  to reflect the change in the value of
          the  underlying  contract as there are by a  purchaser  or seller of a
          currency futures contract.

               A risk in employing currency futures contracts to protect against
          price  volatility of portfolio  securities  which are denominated in a
          particular  currency is that the prices of such securities  subject to
          currency  futures  contracts  may not  completely  correlate  with the
          behavior of the cash prices of the Series' securities. The correlation
          may be distorted by the fact that the currency  futures  market may be
          dominated  by  short-term  traders  seeking to profit from  changes in
          exchange rates. This would reduce the value of such contracts used for
          hedging  purposes  over a  short-term  period.  Such  distortions  are
          generally  minor  and  would  diminish  as  the  contract   approached
          maturity.  Another risk is that N&B  Management  could be incorrect in
          its expectation as to the direction or extent of various exchange rate
          movements or the time span within which the movements take place. When
          a Series  engages in the purchase of currency  futures  contracts,  an
          amount  equal to the market  value of the  currency  futures  contract
          (minus any required margin) will be deposited in a segregated  account
          of securities, cash, or cash equivalents to collateralize the position
          and thereby limit the use of such futures contracts.

               Put and call  options on currency  futures  have  characteristics
          similar to those of other options. In addition to the risks associated
          with investing in options on securities, however, there are particular
          risks associated with transactions in options on currency futures.  In
          particular,  the ability to establish  and close out positions on such
          options will be subject to the development and maintenance of a liquid
          secondary market for such options.

               Options  on Foreign  Currencies.  (All  Series  except AMT Liquid
          Asset  Investments).  Each of these  Series  may  write  and  purchase
          covered  call and put  options on foreign  currencies  (in amounts not
          exceeding  5% of each  Series' net assets,  with respect to AMT Growth
          and  Partners  Investments)  for the  purpose  of  protecting  against
          declines  in  the  U.S.  dollar  value  of  portfolio   securities  or
          protecting  the dollar  equivalent  of  dividend,  interest,  or other
          payment on those  securities and against  increases in the U.S. dollar
          cost of  securities.  A  decline  in the  dollar  value  of a  foreign
          currency in which portfolio securities are denominated will reduce the
          dollar  value of such  securities,  even if their value in the foreign
          currency remains constant.  In order to protect against such decreases
          in the  value of  portfolio  securities,  a Series  may  purchase  put
          options  on the  foreign  currency.  If  the  value  of  the  currency
          declines,  a Series  will have the right to sell such  currency  for a
          fixed  amount  of  dollars  which  exceeds  the  market  value of such
          currency.  This would result in a gain that may offset, in whole or in
          part, the negative effect of currency depreciation on the value of the
          Series' securities denominated in that currency.

               Conversely,  if a rise  in the  dollar  value  of a  currency  is
          projected for those securities to be acquired,  thereby increasing the
          cost of such  securities,  a Series may purchase  call options on such
          currency.  If the value of such  currency  increases,  the purchase of
          such call options  would enable the Series to purchase  currency for a
          fixed  amount of dollars  which is less than the market  value of such
          currency.  Such a purchase would result in a gain that may offset,  at
          least partially,  the effect of any  currency-related  increase in the
          price of  securities  a Series  intends to acquire.  As in the case of
          other  types of options  transactions,  however,  the benefit a Series
          derives from purchasing  foreign  currency  options will be reduced by
          the amount of the premium and related  transaction costs. In addition,
          if  currency  exchange  rates do not move in the  direction  or to the
          extent  anticipated,  a Series could sustain losses on transactions in
          foreign currency options which would deprive it of a portion or all of
          the benefits of advantageous changes in such rates.

               A Series may also write options on foreign currencies for hedging
          purposes. For example, if a Series anticipated a decline in the dollar
          value of foreign currency denominated  securities because of declining
          exchange rates, it could,  instead of purchasing a put option, write a
          call option on the relevant currency.  If the expected decline occurs,
          the option  will most  likely not be  exercised,  and the  decrease in
          value of  portfolio  securities  will be offset  by the  amount of the
          premium received by the Series.

               Similarly,  a Series  could  write a put  option on the  relevant
          currency,  instead of  purchasing a call option,  to hedge  against an
          anticipated  increase in the dollar cost of securities to be acquired.
          If exchange  rates move in the manner  projected,  the put option will
          expire  unexercised and allow the Series to offset such increased cost
          up to the  amount  of the  premium.  However,  as in the case of other
          types of  options  transactions,  the  writing  of a foreign  currency
          option will  constitute  only a partial  hedge up to the amount of the
          premium,  and  only  if  rates  move  in the  expected  direction.  If
          unanticipated  exchange  rate  fluctuations  occur,  the option may be
          exercised  and the Series  would be  required  to purchase or sell the
          underlying  currency  at a loss  which may not be fully  offset by the
          amount of the  premium.  As a result of  writing  options  on  foreign
          currencies,  a Series  also may be required to forego all or a portion
          of  the  benefits  which  might  otherwise  have  been  obtained  from
          favorable  movements in currency  exchange  rates.  Certain options on
          foreign  currencies are traded on the OTC market and involve liquidity
          and   credit   risks   that  may  not  be   present  in  the  case  of
          exchange-traded currency options.
   
               AMT  International  Investments  may  purchase  call  options  on
          currency for non-hedging purposes when N&B Management anticipates that
          the currency will appreciate in value, but the securities  denominated
          in that currency do not present  attractive  investment  opportunities
          and are not  included  in the  Series'  portfolio.  AMT  International
          Investments  may write  (sell)  put and  covered  call  options on any
          currency in order to realize  greater income than would be realized on
          portfolio  securities alone.  However, in writing covered call options
          for additional  income,  AMT International  Investments may forego the
          opportunity  to profit  from an  increase  in the market  value of the
          underlying currency. Also, when writing put options, AMT International
          Investments  accepts, in return for the option premium,  the risk that
          it may be required to purchase the  underlying  currency at a price in
          excess of the currency's market value at the time of purchase.
    
               AMT  International   Investments  would  normally  purchase  call
          options for non-hedging purposes in anticipation of an increase in the
          market  value  of a  currency.  AMT  International  Investments  would
          ordinarily  realize a gain if, during the option period,  the value of
          such currency exceeded the sum of the exercise price, the premium paid
          and  transaction  costs.  Otherwise the Series would realize either no
          gain or a loss on the purchase of the call option.  Put options may be
          purchased  by  AMT  International   Investments  for  the  purpose  of
          benefiting from a decline in the value of currencies which it does not
          own. The Series would ordinarily  realize a gain if, during the option
          period,  the  value of the  underlying  currency  decreased  below the
          exercise  price  sufficiently  to more  than  cover  the  premium  and
          transaction  costs.  Otherwise the Series would realize either no gain
          or a loss on the purchase of the put option.

               A  call  option  written  on  foreign  currency  by a  Series  is
          "covered" if the Series owns the underlying  foreign  currency subject
          to the call, or if it has an absolute and  immediate  right to acquire
          that foreign currency without additional cash consideration. This also
          would apply to  additional  cash  consideration  held in a  segregated
          account by its custodian, upon conversion or exchange of other foreign
          currency  held in its  portfolio.  A call option is also  covered if a
          Series  holds  a call  on the  same  foreign  currency  for  the  same
          principal  amount as the call written where the exercise  price of the
          call held is (a) equal to or less than the exercise  price of the call
          written or (b) greater than the exercise  price of the call written if
          the amount of the  difference  is  maintained by the Series in cash or
          liquid,  high-grade debt  securities in a segregated  account with its
          custodian.

               Limitations on  Transactions  in Options,  Futures  Contracts and
          Foreign Currency Transactions. A Series is required to maintain margin
          deposits  with  brokerage  firms  through  which  it  effects  futures
          contracts,  and must deposit "initial margin" each time it enters into
          a futures  contract.  Such  "initial  margin"  is  usually  equal to a
          percentage  of the  contract's  value.  In  addition,  due to  current
          industry  practice,  daily  variation  margin  payments  in  cash  are
          required to reflect gains and losses on open futures  contracts.  As a
          result,  a Series may be required to make  additional  margin payments
          during the term of a futures  contract.  A Series may not  purchase or
          sell futures  contracts  (including  currency  futures  contracts)  or
          related options on foreign or U.S. exchanges if immediately thereafter
          the sum of the  amounts  of initial  margin  deposits  on the  Series'
          existing  futures  contracts  and premiums paid for options on futures
          (excluding  futures  contracts and options on futures entered into for
          bona fide hedging purposes and net of the amount the positions are "in
          the money")  would exceed 5% of the market value of the Series'  total
          assets.  In instances  involving the purchase of futures  contracts or
          the  writing of put  options  thereon by a Series,  an amount of cash,
          cash equivalents or securities denominated in the appropriate currency
          equal to the market value of the futures  contracts  and options (less
          any related margin deposits) will be deposited in a segregated account
          with its custodian to collateralize the position, thereby limiting the
          use of such futures contracts.

               The extent to which a Series may enter into futures contracts and
          option  transactions  may be  limited by the  requirements  of federal
          income  tax  law  applicable  to  its   corresponding   Portfolio  for
          qualification  as a RIC. See  "Additional  Tax  Information." A Series
          generally  will  not  enter  into a  forward  contract  with a term of
          greater  than  one  year.  A  Series  may  experience  delays  in  the
          settlement of its foreign currency transactions.

               When a  Series  engages  in  forward  contracts  for the  sale or
          purchase of  currencies,  the Series will either cover its position or
          establish a segregated account.  The Series will consider its position
          covered if it has  securities  in the currency  subject to the forward
          contract,  or  otherwise  has the right to obtain that  currency at no
          additional cost. In the alternative,  the Series will place cash which
          is not available for investment, liquid, high-grade debt securities or
          other  securities  (denominated in the foreign currency subject to the
          forward contract) in a separate account.  The amounts in such separate
          account  will equal the value of the Series'  total  assets  which are
          committed to the consummation of foreign currency exchange  contracts.
          If the  value  of  the  securities  placed  in  the  separate  account
          declines,  the Series will place  additional cash or securities in the
          account on a daily basis so that the value of the  account  will equal
          the amount of the Series' commitments with respect to such contracts.
   
               Short  Sales  (AMT  Partners  Investments,   Growth  Investments,
          Balanced  Investments and  International  Investments) and Short Sales
          Against-the-Box   (AMT  Partners   Investments,   Growth  Investments,
          Balanced Investments, Liquid Asset Investments,  Limited Maturity Bond
          Investments  and  International  Investments).  AMT Partners,  Growth,
          Balanced, and International  Investments may enter into short sales of
          securities  to the  extent  permitted  by the  Series'  nonfundamental
          investment  policies and limitations.  Under applicable  guidelines of
          the staff of the SEC, if a Series  engages in a short sale of the type
          referred to in the  Prospectus,  it must put in a  segregated  account
          (not with the broker) an amount of cash or U.S. government  securities
          equal to the difference between (1) the market value of the securities
          sold  short at the time they were sold  short and (2) any cash or U.S.
          government  securities required to be deposited as collateral with the
          broker in connection  with the short sale (not  including the proceeds
          from the short  sale).  In  addition,  until the Series  replaces  the
          borrowed  security,  it must daily maintain the segregated  account at
          such a level  that (3) the  amount  deposited  in it plus  the  amount
          deposited with the broker as collateral  will equal the current market
          value of the securities sold short, and (4) the amount deposited in it
          plus the amount  deposited  with the broker as collateral  will not be
          less than the  market  value of the  securities  at the time they were
          sold short.
    
   
               The effect on the Series of engaging in short  selling is similar
          to the effect of leverage. Short selling may exaggerate changes in the
          corresponding  Portfolio's  NAV and  yield.  Short  selling  may  also
          produce  higher than  normal  portfolio  turnover  which may result in
          increased transaction costs to the Series and may result in gains from
          the sale of  securities  deemed to have been held for less than  three
          months.  Such gains must be limited in order for the Series to qualify
          as a RIC. See "Additional Tax Information."

               AMT  Liquid  Asset,  Limited  Maturity  Bond,  Partners,  Growth,
          Balanced   and   International   Investments   may  make  short  sales
          against-the-box.  A short sale is "against-the-box" when, at all times
          during which a short position is open, the Series owns an equal amount
          of such securities,  or owns securities  giving it the right,  without
          payment  of  future  consideration,  to  obtain  an  equal  amount  of
          securities sold short.
    
               Foreign,  Corporate and  Government Debt  Securities.   (All
          Series). Each  Series may invest  in foreign corporate  bonds and
          debentures and sovereign debt instruments issued or guaranteed by
          foreign governments, their agencies or instrumentalities.

               Foreign debt  securities are subject to risks similar to those of
          other foreign  securities.  In addition,  foreign debt  securities are
          subject to the risk of an issuer's  inability  to meet  principal  and
          interest  payments  on the  obligations  ("credit  risk") and are also
          subject  to price  volatility  due to such  factors as  interest  rate
          sensitivity,  market perception of the creditworthiness of the issuer,
          and general market liquidity ("market risk").  Lower-rated  securities
          are more likely to react to developments  affecting  market and credit
          risk than are more highly rated  securities,  which react primarily to
          movements in the general level of interest  rates.  Debt securities in
          the lowest rating categories may involve a substantial risk of default
          or may be in default.  Changes in economic  conditions or developments
          regarding  the  individual  issuer  are more  likely  to  cause  price
          volatility  and weaken the capacity of the issuers of such  securities
          to make  principal  and interest  payments than is the case for higher
          grade debt securities.  An economic downturn  affecting the issuer may
          result  in  an  increased   incidence  of  default.   The  market  for
          lower-rated  securities  may be  thinner  and  less  active  than  for
          higher-rated securities.  Pricing of thinly traded securities requires
          greater   judgment  than  pricing  of  securities   for  which  market
          transactions are regularly reported. N&B Management        will invest
          in such securities only when it concludes that the anticipated  return
          to the  Series  and  the  Portfolio  on such  an  investment  warrants
          exposure to the additional level of risk. A further description of the
          ratings  used by Moody's and S&P is  included  in the  Appendix to the
          SAI.  Subsequent to its purchase by the Series, an issue of securities
          may cease to be rated or its  rating may be  reduced.  In such a case,
          N&B  Management         will  make a  determination  as to whether the
          Series should dispose of the downgraded securities.

               Convertible  Securities.  (AMT  International  Investments,   AMT
          Growth  Investments,   AMT  Balanced  Investments,  and  AMT  Partners
          Investments).  A convertible  security  entitles the holder to receive
          interest  paid or accrued on debt or the  dividend  paid on  preferred
          stock until the convertible security matures or is redeemed, converted
          or exchanged.  Before conversion,  convertible  securities  ordinarily
          provide a stream of income with generally  higher yields than those of
          common stocks of the same or similar issuers, but lower than the yield
          on   non-convertible   debt.   Convertible   securities   are  usually
          subordinated to comparable-  tier  nonconvertible  securities but rank
          senior to common stock in a corporation's capital structure. The value
          of a convertible security is a function of (1) its yield in comparison
          with the yields of other securities of comparable maturity and quality
          that do not have a conversion  privilege and (2) its worth,  at market
          value, if converted into the underlying common stock.

               Convertible   securities   are   typically   issued  by   smaller
          capitalized companies whose stock prices may be volatile. The price of
          a convertible  security often reflects such variations in the price of
          the  underlying  common stock in a way that  nonconvertible  debt does
          not. A convertible security may be subject to redemption at the option
          of the  issuer  at a price  established  in the  security's  governing
          instrument.  If a convertible  security held by a Series is called for
          redemption,  the  Series  will be  required  to  convert  it into  the
          underlying common stock, sell it to a third party or permit the issuer
          to redeem the  security.  Any of these  actions  could have an adverse
          effect on the fund's ability to achieve its investment objective.

               Preferred  Stock.  (AMT  International  Investments,  AMT  Growth
          Investments,  AMT Balanced Investments and AMT Partners  Investments).
          Unlike interest  payments on debt  securities,  dividends on preferred
          stock are generally payable at the discretion of the issuer's board of
          directors,  although preferred shareholders may have certain rights if
          dividends  are not paid.  Shareholders  may  suffer a loss of value if
          dividends are not paid, and generally  have no legal recourse  against
          the issuer.  The market prices of preferred  stocks are generally more
          sensitive  to changes in the  issuer's  creditworthiness  than are the
          prices of debt securities.

               Commercial Paper. (All Series).  Commercial paper is a short-term
          debt  security  issued by a  corporation  or bank for purposes such as
          financing current operations.  AMT Growth, Partners,  Liquid Asset and
          International   Investments  may  invest  only  in  commercial   paper
          receiving  the  highest  rating  from S&P (A-1) or Moody's  (P-1),  or
          deemed  by N&B  Management         to be of  equivalent  quality.  AMT
          International  Investments may invest in such  commercial  paper, as a
          defensive  measure,  to maintain  adequate  liquidity or as needed for
          segregated accounts.

               Each Series may invest in commercial  paper that cannot be resold
          to the public without an effective  registration  statement  under the
          1933  Act.  While  such  restricted  securities  are  normally  deemed
          illiquid,  N&B Management          may in certain cases determine that
          such paper is liquid,  pursuant to guidelines  established by Managers
          Trust's Board of Trustees.

               Zero Coupon  Securities.  (All Series).  Each of these Series may
          invest in zero coupon  securities  (up to 5% of its net  assets,  with
          respect to AMT  Partners  Investments  and AMT Limited  Maturity  Bond
          Investments),  which  are debt  obligations  that do not  entitle  the
          holder to any  periodic  payment  of  interest  prior to  maturity  or
          specify  a  future  date  when the  securities  begin  paying  current
          interest.  Rather, they are issued and traded at a discount from their
          face  amount  or  par  value,   which  discount  varies  depending  on
          prevailing  interest  rates,  the time  remaining  until cash payments
          begin, the liquidity of the security, and the perceived credit quality
          of the issuer.

               The  discount  on  zero  coupon   securities   ("original   issue
          discount")  is taken into  account by each Series prior to the receipt
          of any actual payments.  Because each Portfolio must distribute to its
          shareholders  substantially  all of its income (including its share of
          its  corresponding  Series'  original  issue  discount) for income tax
          purposes  (see  "Additional  Tax  Information"),  a Series may have to
          dispose of portfolio securities under disadvantageous circumstances to
          generate  cash,  or  may  be  required  to  borrow,   to  satisfy  its
          corresponding Portfolio's distribution requirements.

               The market  prices of zero coupon  securities  generally are more
          volatile than the prices of securities that pay interest  periodically
          and are likely to respond  to changes in  interest  rates to a greater
          degree  than  do  other  types  of  debt  securities   having  similar
          maturities and credit quality.

               Municipal Obligations. (AMT Limited Maturity Bond Investments and
          AMT Balanced  Investments).  Municipal obligations are issued by or on
          behalf of states (as used herein, including the District of Columbia),
          territories  and  possessions of the United States and their political
          subdivisions,  agencies, and instrumentalities;  the interest on which
          is exempt from  federal  income  tax.  Municipal  obligations  include
          "general obligation"  securities,  which are backed by the full taxing
          power of a municipality,  and "revenue"  securities,  which are backed
          only  by the  income  from  a  specific  project,  facility,  or  tax.
          Municipal obligations also include industrial  development and private
          activity bonds which are issued by or on behalf of public authorities,
          but are  not  backed  by the  credit  of any  governmental  or  public
          authority. "Anticipation notes", which are also municipal obligations,
          are issued by  municipalities  in expectation of future  proceeds from
          the  issuance  of  bonds,  or from  taxes or other  revenues,  and are
          payable  from those  bond  proceeds,  taxes,  or  revenues.  Municipal
          obligations also include tax-exempt  commercial paper, which is issued
          by  municipalities  to help  finance  short-term  capital or operating
          requirements.

               The value of municipal obligations is dependent on the continuing
          payment  of  interest  and  principal  when due by the  issuers of the
          municipal  obligations  in which a Series  invests (or, in the case of
          industrial  development  bonds, the revenues generated by the facility
          financed by the bonds or, in certain other instances,  the provider of
          the credit  facility  backing the bonds).  As with other fixed  income
          securities,  an increase in interest  rates  generally will reduce the
          value of the Series' investments in municipal  obligations,  whereas a
          decline in interest rates generally will increase that value.  Current
          efforts to restructure the federal budget and the relationship between
          the federal  government and state and local governments may impact the
          financing  of some issuers of  municipal  securities.  Some states and
          localities  are  experiencing  substantial  deficits  and may  find it
          difficult for political or economic reasons to increase taxes. Both of
          these  factors  could  affect the  ability  of an issuer of  municipal
          securities to meet its obligations.

               Interest Rate Protection  Transactions.  (AMT  Government  Income
          Investments).   AMT  Government  Income  Investments  may  enter  into
          interest rate swaps, caps, floors, and collars.  An interest rate swap
          involves an agreement  between two parties to exchange  payments  that
          are based,  for  example,  on variable and fixed rates of interest and
          that are calculated on the basis of a specified  amount (the "notional
          principal amount"). In an interest rate cap or floor transaction,  one
          party  agrees to make  payments  to the other  party when a  specified
          market  interest  rate goes  above (in the case of a cap) or below (in
          the case of a  floor) a  designated  level on  predetermined  dates or
          during a specified  time period.  An interest rate collar  transaction
          involves  both a cap and a floor  (that is,  one party  agrees to make
          payments to the other party when a specified market interest rate goes
          outside a specified range).

               The Series  enters  into these  transactions  only with banks and
          recognized  securities  dealers  believed by N&B Management to present
          minimal credit risks in accordance with guidelines  established by the
          Trustees,  for the purpose of (1)  preserving  a return or spread on a
          particular  investment  or portion of its  portfolio,  (2)  protecting
          against  an  increase  in  the  price  of  securities  it  anticipates
          purchasing  at a later  date,  or (3)  effectively  fixing the rate of
          interest  it  pays  on  borrowings.  The  Series  uses  interest  rate
          protection transactions as hedges and not as speculative  investments;
          these  transactions are subject to risks comparable to those described
          herein with respect to other hedging strategies.  If the Series enters
          into  such a  transaction  and N&B  Management  incorrectly  forecasts
          interest rates,  market values, or other economic factors,  the Series
          would have been in a better  position  had it not  hedged at all.  The
          Series  does not treat  these  transactions  as being  subject  to its
          borrowing restrictions.

               The  Series  will  maintain   appropriate   liquid  assets  in  a
          segregated  custodial  account to cover its current  obligations under
          swap  agreements.  If the Series enters into a swap agreement on a net
          basis,  it will segregate  assets with a daily value at least equal to
          the  excess,  if  any,  of its  accrued  obligations  under  the  swap
          agreement  over the accrued amount it is entitled to receive under the
          agreement.  If the Series enters into a swap agreement on other than a
          net basis,  it will  segregate  assets  with a value equal to the full
          amount of its accrued obligations under the agreement.

               The swap market has grown  substantially in recent years,  with a
          large  number  of  the  participants   utilizing   standardized   swap
          documentation.  Swap  agreements  are treated as liquid if they can be
          expected,  in N&B Management's  judgment, to be able to be sold within
          seven days at approximately the price at which they are valued.  Caps,
          floors,   and   collars  are  more   recent   innovations   for  which
          documentation  is less  standardized,  and  accordingly  they are less
          liquid than swaps.

               Short-Term  Trading.  (AMT Government  Income  Investments).  AMT
          Government  Income  Investments  may  engage  in  short-term  trading.
          Securities may be sold in  anticipation of a market decline (a rise in
          interest  rates) or  purchased  in  anticipation  of a market  rise (a
          decline in interest  rates).  In addition,  a security may be sold and
          another  purchased at approximately the same time to take advantage of
          what N&B Management believes to be a temporary disparity in the normal
          yield relationship  between the two securities.  Yield disparities may
          occur for reasons not directly  related to the  investment  quality of
          particular  issues or the general movement of interest rates,  such as
          changes in the overall  demand for or supply of various types of fixed
          income   securities  or  changes  in  the  investment   objectives  of
          investors.
   
               Fixed Income Securities.  (All Series). Each Series may invest in
          money market instruments,  U.S.  Government or Agency securities,  and
          corporate  bonds  and  debentures  receiving  one of the four  highest
          ratings from S&P, Moody's,  or any other NRSRO or, if not rated by any
          NRSRO,  deemed  comparable by N&B Management to such rated  securities
          ("Comparable   Unrated   Securities");   in  addition,   AMT  Partners
          Investments  may invest up to 15% of its net  assets,  measured at the
          time  of  investment,   in  corporate  debt  securities   rated  below
          investment  grade  or  Comparable  Unrated  Securities.   AMT  Limited
          Maturity  Bond  Investments  may  invest up to 10% of its net  assets,
          measured at the time of  investment,  in debt  securities  rated below
          investment  grade,  but rated no lower  than B by S&P or  Moody's,  or
          Comparable Unrated Securities;  AMT Balanced Investments may invest up
          to 10% of the debt securities portion of its investments,  measured at
          the time of  investment,  in debt  securities  rated below  investment
          grade,  but rated no lower  than B by S&P or  Moody's,  or  Comparable
          Unrated  Securities.  The ratings of an NRSRO represent its opinion as
          to the quality of securities  it  undertakes to rate.  Ratings are not
          absolute standards of quality; consequently,  securities with the same
          maturity,  coupon,  and rating  may have  different  yields.  A Series
          relies on the credit  evaluations  performed by N&B  Management and on
          ratings assigned by S&P and Moody's, which are described in Appendix A
          to this SAI.
    
               Fixed  income  securities  are subject to the risk of an issuer's
          inability to meet principal and interest  payments on the  obligations
          ("credit  risk") and also may be subject  to price  volatility  due to
          such factors as interest rate  sensitivity,  market  perception of the
          creditworthiness  of the issuer, and general market liquidity ("market
          risk").   Lower-rated   securities   are  more   likely  to  react  to
          developments  affecting  market and credit  risk than are more  highly
          rated  securities,  which react  primarily to movements in the general
          level of interest  rates.  Subsequent  to its  purchase by a Series an
          issue  of  securities  may  cease to be  rated  or its  rating  may be
          reduced,  so that the securities would not be eligible for purchase by
          the  Series.  In such a case,  with  respect to all Series  except AMT
          Liquid Asset  Investments,  N&B  Management         will  engage in an
          orderly  disposition  of  the  downgraded  securities  to  the  extent
          necessary to ensure that the Series'  holdings of such securities will
          not exceed 5% of the Series' net  assets.  With  respect to AMT Liquid
          Asset Investments, N&B Management will consider the need to dispose of
          such securities in accordance with the requirements of Rule 2a-7.

                           CERTAIN RISK CONSIDERATIONS

               Although  each  Series  seeks to reduce  risk by  investing  in a
          diversified  portfolio,  diversification  does not eliminate all risk.
          There can, of course, be no assurance that any Series will achieve its
          investment  objective,  and  an  investment  in a  Portfolio  involves
          certain risks that are described in the sections entitled  "Investment
          Program"  and  "Description  of  Investments"  in the  Prospectus  and
          "Investment Information" in this SAI.

                             PERFORMANCE INFORMATION

               A Portfolio's  performance  may be quoted in advertising in terms
          of yield or total return if accompanied by performance of an insurance
          company's separate account.  Each Portfolio's  performance figures are
          based on historical  earnings and are not intended to indicate  future
          performance.  The share price  (except in the case of the Liquid Asset
          Portfolio), yield and total return of each Portfolio will vary, and an
          investment in the Portfolio,  when redeemed, may be worth more or less
          than the original purchase price.

          Yield Calculations

               The Liquid Asset  Portfolio may advertise its "current yield" and
          "effective  yield."  The  Portfolio's  current  yield  is  based  on a
          seven-day  period  and is  computed  by  determining  the  net  change
          (excluding  capital  changes) in the value of a  hypothetical  account
          having  a  balance  of one  share  at  the  beginning  of the  period,
          subtracting  a  hypothetical   charge   reflecting   deductions   from
          shareholder accounts,  and dividing the difference by the value of the
          account at the  beginning  of the base  period.  The result is a "base
          period  return,"  which is then  annualized  -- that is, the amount of
          income  generated  during  the  seven-day  period  is  assumed  to  be
          generated  each week  over a 52-week  period -- and shown as an annual
          percentage of the investment.

               The effective yield of the Portfolio is calculated similarly, but
          the base  period  return is  assumed  to be  reinvested.  The  assumed
          reinvestment  is  calculated  by adding 1 to the base  period  return,
          raising  the  sum to a  power  equal  to 365  divided  by  seven,  and
          subtracting one from the result, according to the following formula:

          Effective Yield = [(Base Period Return + 1)superscript365/7] - 1
   
               For the seven  calendar days ended December 31, 1995, the current
          yield of the Liquid Asset  Portfolio  was 4.74%.  For the same period,
          the effective yield was 4.85%.
    
               Limited Maturity Bond Portfolio and Government  Income Portfolio.
          Each of these  Portfolios  may advertise its "yield" based on a 30-day
          (or  one-month)  period.  This yield is computed  by dividing  the net
          investment  income per share  earned  during the period by the maximum
          offering  price per share on the last day of the  period.  The  result
          then  is  annualized  and  shown  as  an  annual   percentage  of  the
          investment.
   
               The annualized  yield for the Limited Maturity Bond Portfolio and
          the Government  Income  Portfolio for the 30-day period ended December
          31, 1995 was 5.19% and 5.33%, respectively.
    
          Total Return  Computations. (All  Portfolios except  Liquid Asset
          and International).

               A Portfolio may advertise  certain total return  information.  An
          average  annual  compounded  rate of return  ("T") may be  computed by
          using the redeemable value at the end of a specified period ("ERV") of
          a  hypothetical  initial  investment  of $1,000 ("P") over a period of
          time ("n") according to the formula:

                           P(1 + T)superscript n = ERV

          The average  annual total return smooths out  year-to-year  variations
          and, in that respect,  differs from actual  year-to-year  results.  Of
          course,  past  performance  cannot be a guarantee  of future  results.
          These  calculations  assume that all dividends and  distributions  are
          reinvested.
   
               The average  annual total returns for the Growth  Portfolio  (and
          the predecessor of the Growth Portfolio for the period prior to May 1,
          1995) for the one-,  five-,  and ten-year  periods ended  December 31,
          1995, were 31.73%, 13.69%, and 12.01%, respectively.

               The average  annual total  returns for the Limited  Maturity Bond
          Portfolio (and the predecessor of the Limited  Maturity Bond Portfolio
          for the period prior to May 1, 1995) for the one-, five-, and ten-year
          periods  ended  December 31,  1995,  were  10.94%,  6.70%,  and 7.61%,
          respectively.

               The average annual total returns for the Balanced  Portfolio (and
          the predecessor of the Balanced  Portfolio for the period prior to May
          1, 1995) for the one-year and  five-year  periods  ended  December 31,
          1995,  and for the period  from  February  28, 1989  (commencement  of
          operations),  through  December 31, 1995,  were  23.76%,  11.04%,  and
          10.69%, respectively.

               The average  annual total return for the Partners  Portfolio (and
          the Predecessor of the Partners  Portfolio for the period prior to May
          1, 1995) for the one year period  ended  December 31, 1995 and for the
          period  from  March 22,  1994  (commencement  of  operations)  through
          December 31, 1995 was 36.47% and 17.54%, respectively.

               The  average  annual  total  return  for  the  Government  Income
          Portfolio (and the predecessor of the Government  Income Portfolio for
          the  period  prior  to May 1,  1995)  for the  one-year  period  ended
          December 31, 1995 and from March 22, 1994 (commencement of operations)
          through December 31, 1995 was 11.76% and 7.34%, respectively.
    
   
              N&B  Management  has  reimbursed  certain  of the  Portfolios  and
          predecessors of the Portfolios for certain expenses during the periods
          shown, which has the effect of increasing total return.
    
                 Average  annual total returns quoted for the Portfolios include
          the effect of deducting a  Portfolio's  expenses,  but may not include
          charges and expenses attributable to any particular insurance product.
          Since you can only purchase  shares of a Portfolio  through a variable
          annuity or variable  life  insurance  contract,  you should  carefully
          review the  prospectus  of the  insurance  product you have chosen for
          information on relevant charges and expenses.  Excluding these charges
          from  quotations  of a  Portfolio's  performance  has  the  effect  of
          increasing the performance  quoted. You should bear in mind the effect
          of these charges when  comparing a Portfolio's  performance to that of
          other mutual funds.

          Comparative Information

               other domestic,  international,  and global indices.  The S&P 500
               Index is a broad  index of common  stock  prices,  while the DJIA
               represents a narrower  segment of industrial  companies.  The S&P
               600  includes  stocks that range in market value from $27 million
               to $880  million,  with an average of $302  million.  The S&P 400
               measures    mid-sized    companies   with   an   average   market
               capitalization  of $1.2  billion.  The EAFE Index is an unmanaged
               index of common  stock  prices of more  than 900  companies  from
               Europe, Australia, and the Far East translated into U.S. dollars.
               The   Financial   Times  World  XUS  Index  is  an  index  of  24
               international  markets,  excluding the U.S. market.  Each assumes
               reinvestment of distributions and is calculated without regard to
               tax consequences or the costs of investing. The Portfolios invest
               in different  types of securities  from those included in some of
               these indices.

          *   Indicates  an "interested  person" of  each Trust  within the
          meaning  of  the  1940  Act.   Messrs.  Egener  and  Zicklin  are
          interested persons by  virtue of the fact that  they are officers
          and directors of N&B Management and partners of Neuberger&Berman.
          Mr. Trapp is  an interested  person by  virtue of  the fact  that
          until November 30,  1994 he  was an  officer of one  of the  Life
          Company shareholders of the Trust.

               The Trust's Trust Instrument and Managers Trust's  Declaration of
          Trust  provides  that  they  will  indemnify  the  Trustees  and their
          officers  against  liabilities  and  expenses  reasonably  incurred in
          connection  with  litigation in which they may be involved  because of
          their offices with the Trust or Advisers Trust,  respectively,  unless
          it is adjudicated that they engaged in bad faith,  wilful misfeasance,
          gross  negligence,  or reckless  disregard  of the duties  involved in
          their offices. In the case of settlement,  such  indemnification  will
          not be provided  unless it has been  determined -- by a court or other
          body approving the settlement or other  disposition,  or by a majority
          of disinterested  Trustees,  based upon a review of readily  available
          facts,  or in a written  opinion of independent  counsel - - that such
          officers  or  Trustees  have not  engaged in wilful  misfeasance,  bad
          faith, gross negligence, or reckless disregard of their duties.

               Trustees who are not  officers or  employees  of N&B  Management,
          Neuberger&Berman  and/or the Life Companies or any of their affiliates
          are paid trustees' fees. For the year ended December 31, 1995, a total
          of  $38,500  in fees  was  paid  to the  Trustees  as a  group  by the
          predecessor to the Trust. The following table shows 1995  compensation

               Shares of the  Portfolios  are issued and redeemed in  connection
          with  investments  in and  payments  under  certain  variable  annuity
          contracts  and  variable  life   insurance   policies   (collectively,
          "Variable   Contracts")  issued  through  separate  accounts  of  life
          insurance  companies  (the "Life  Companies").  Shares of the Balanced
          Portfolio are also offered  directly to Qualified  Plans.  As of April
          10, 1996 the separate accounts of the Life Companies were known to the
          Board of Trustees and the management of the Trust to own of record all
          shares of the Growth,  Liquid Asset,  Limited Maturity Bond, Partners,
          and Government Income Portfolios of the Trust and approximately 98% of
          the  shares of the  Balanced  Portfolio  of the  Trust.  There were no
          shareholders  of the  International  Portfolio as of this same date. A
          Trustee of the Trust owns a Variable  Contract,  the underlying  Trust
          shares of which  constitute  less than 1% of the  total  Trust  shares
          issued and outstanding.

             INVESTMENT MANAGEMENT, ADVISORY AND ADMINISTRATION SERVICES

               All Portfolios and their corresponding Series
   
               Neuberger&Berman   is  an   investment   management   firm   with
          headquarters  in New York.  The firm's focus is on U.S.  fixed income,
          equity and balanced fund management.  Total assets under management by
          Neuberger&Berman  and its affiliates were approximately  $38.7 billion
          as of December 31, 1995. Founded in 1939 to manage portfolios for high
          net worth  individuals,  the firm  entered the mutual fund  management
          business in 1950,  and began  offering  active  management for pension
          funds and  institutions  in the  mid-1970's.  Most money managers that
          come to the Neuberger&Berman  organization have at least fifteen years
          of experience.  Neuberger&Berman and N&B Management employ experienced
          professionals that work in a competitive environment.
    
   
               Because all of the Portfolios' net investable assets are invested
          in  their  corresponding   Series,  the  Portfolios  do  not  need  an
          investment  manager.  N&B Management serves as each Series' investment
          manager pursuant to a Management  Agreement  ("Management  Agreement")
          dated  as of May 1,  1995  that was  approved  by the  holders  of the
          interests  in all the Series on April 13, 1994 (except with respect to
          AMT  International  Investments).   The  Trustees  of  Managers  Trust
          approved the Management Agreement between AMT International Investment
          and N&B Management on November 30, 1995.
    
   
               The   Management   Agreement   provides  in  substance  that  N&B
          Management will make and implement investment decisions for the Series
          in its discretion and will continuously  develop an investment program
          for  each  Series'  assets.  The  Management   Agreement  permits  N&B
          Management to effect securities  transactions on behalf of each Series
          through associated persons of N&B Management. The Management Agreement
          also specifically permits N&B Management to compensate, through higher
          commissions,  brokers and dealers who provide investment  research and
          analysis to the Series,  but N&B Management has no current plans to do
          so.
    
   
               N&B  Management  provides to each Series,  without  cost,  office
          space,  equipment,  and facilities and personnel  necessary to perform
          executive,   administrative,  and  clerical  functions  and  pays  all
          salaries,  expenses, and fees of the officers, trustees, and employees
          of Managers  Trust who are  officers,  directors,  or employees of N&B
          Management.  Two officers of N&B Management  (who also are partners of
          Neuberger&Berman),  who also  serve as  directors  of N&B  Management,
          presently serve as trustees and officers of the Trusts.  See "Trustees
          and Officers." N&B Management provides similar facilities and services
          to each Portfolio pursuant to an administration agreement dated May 1,
          1995  ("Administration  Agreement").  Each Portfolio was authorized to
          become subject to the Administration Agreement by vote of the Trustees
          on May 26, 1994, and became subject to it on May 1, 1995.

               Prior to May 1, 1995, N&B Management provided investment advisory
          and  administrative  services  to the  predecessor  of each  Portfolio
          (except the  International  Portfolio)  under an  Investment  Advisory
          Agreement ("Prior Agreement") with that Portfolio. As compensation for
          these  services,  the  predecessors  to the Liquid Asset Portfolio and
          Limited  Maturity  Bond  Portfolio  paid N&B  Management  a fee at the
          annual  rate of 0.50% of the  average  daily net assets of each of the
          two  Portfolios;  the predecessor to the Government  Income  Portfolio
          paid N&B  Management  a fee at the annual rate of 0.60% of the average
          daily net assets of the  Portfolio;  the  predecessor  to the Balanced
          Portfolio paid N&B Management a fee at the annual rate of 0.70% of the
          average daily net assets of the Portfolio; and the predecessors to the
          Growth and Partners  Portfolios  paid N&B Management a fee at the rate
          of 0.70% of the first $250 million of average  asset value,  0.675% of
          the next $250 million of average  asset value,  0.65% of the next $250
          million of average  asset  value,  0.625% of the next $250  million of
          average asset value, and 0.60% of the average asset value in excess of
          $1 billion. The fee rate paid by each predecessor  Portfolio under its
          Prior  Agreement  is 0.15%  lower  than the  combined  management  and
          administrative fees paid by the corresponding  successor Portfolio and
          its  corresponding  Series  under the  Management  and  Administration
          Agreements.  For a description of the  Management  and  Administration
          fees currently in effect,  see "Management and  Administration" in the
          Prospectus.

               The Portfolios  (and the  predecessors  of the Portfolios for the
          period  prior to May 1, 1995) paid  advisory  fees for the years ended
          December   31,  1993,   1994  and  paid   advisory,   management   and
          administration fees in 1995. For the year ended December 31, 1993, N&B
          Management  was paid advisory fees as follows:  $44,324,  Liquid Asset
          Portfolio;  $2,376,645, Growth Portfolio; $1,304,236, Limited Maturity
          Bond Portfolio;  and $879,956,  Balanced Portfolio. For the year ended
          December 31, 1994,  N&B  Management was paid advisory fees as follows:
          $28,699,   Liquid  Asset  Portfolio;   $2,508,627   Growth  Portfolio;
          $1,806,336,  Limited  Maturity Bond  Portfolio;  $1,217,370,  Balanced
          Portfolio.  For the period ended December 31, 1994, N&B Management was
          paid  advisory  fees  of  $4,752,  Government  Income  Portfolio;  and
          $19,769, Partners Portfolio. For the year ended December 31, 1995, N&B
          Management was paid investment management, advisory and administration
          fees as follows  (amounts for each Portfolio  include  management fees
          paid by that Portfolio's  corresponding Series for the period from May
          1 to December 31, 1995): $73,935, Liquid Asset Portfolio;  $4,086,084,
          Growth  Portfolio;   $2,076,233,   Limited  Maturity  Bond  Portfolio;
          $1,584,350,  Balanced Portfolio; $10,555, Government Income Portfolio;
          and $520,757, Partners Portfolio.
    
               The Management and Administration  Agreements each continue until
          May 1, 1997 with  respect to each Series or  Portfolio,  respectively.
          The  Management  Agreement is renewable  thereafter  from year to year
          with respect to each Series, so long as its continuance is approved at
          least  annually  (1) by the vote of a  majority  of  Managers  Trust's
          Trustees  who  are  not  "interested  persons"  of N&B  Management  or
          Managers Trust  ("Independent  Series Trustees"),  cast in person at a
          meeting called for the purpose of voting on such approval,  and (2) by
          the vote of a majority of Managers  Trust's  Trustees or by a 1940 Act
          majority  vote of the  outstanding  shares in that  Series.  After the
          first two years, the  Administration  Agreement is renewable from year
          to year with respect to a  Portfolio,  so long as its  continuance  is
          approved  at  least  annually  (1) by the  vote of a  majority  of the
          Portfolio Trustees who are not "interested  persons" of N&B Management
          or the Trust ("Independent  Portfolio Trustees"),  cast in person at a
          meeting called for the purpose of voting on such approval,  and (2) by
          the vote of a  majority  of the  Portfolio  Trustees  or by a 1940 Act
          majority  vote  of the  outstanding  shares  in  that  Portfolio.  The
          Management  Agreement is terminable  with respect to a Series  without
          penalty on 60 days' written  notice either by Managers Trust or by N&B
          Management. The Administration Agreement is terminable with respect to
          a Portfolio  without penalty by N&B Management upon at least 120 days'
          prior  written  notice  to the  Portfolio,  and by  the  Portfolio  if
          authorized  by the  Portfolio  Trustees,  including  a majority of the
          Independent Portfolio Trustees, on at least 30 days' written notice to
          N&B  Management.  Each  Agreement  terminates  automatically  if it is
          assigned.

                 Expense Limitation

               All Portfolios and their corresponding Series       
   
               As noted in the Prospectus under "Management and Administration -
          Expenses,"  N&B Management  has  voluntarily  undertaken to limit each
          Portfolio's   expenses  by  reimbursing  each  Portfolio  for  certain
          operating  expenses  (including,  if  necessary,  the fees  under  the
          Administration Agreement with respect to the Government Income, Liquid
          Asset,  and  International  Portfolios)  and its pro rata share of its
          corresponding Series' operating expenses (including, if necessary, its
          fees under the  Management  Agreement  with respect to the  Government
          Income and Liquid Asset  Portfolios).  A similar  arrangement  existed
          with respect to the  predecessors  of these  Portfolios.  For the year
          ended December 31, 1995,  N&B  Management  reimbursed the Liquid Asset
          and Government  Income Portfolios  $27,683 and $46,494,  respectively.
          For the  year or  period  ended  December  31,  1994,  N&B  Management
          reimbursed the predecessors of the Liquid Asset and Government  Income
          Portfolios  $785 and $11,752,  respectively.  No  reimbursements  were
          necessary  for the years ended  December 31, 1993 for the  predecessor
          fund of the Liquid Asset Portfolio.  The  International  Portfolio and
          AMT  International   Investments  had  not  yet  commenced  investment
          operations as of December 31, 1995.

               As noted in the Prospectus under "Management and Administration -
          Expenses," N&B  Management has undertaken to limits certain  operating
          expenses  of  AMT  International  Investments  and  the  International
          Portfolio,   respectively.   The   International   Portfolio  and  AMT
          International   Investments   have   not  yet   commenced   investment
          operations.

          partners of Neuberger&Berman.

               Messrs.  Egener and Zicklin  are trustees and  officers, and
          Messrs.  Sullivan, Weiner, and Russell and Mmes. Brandon, Cooper-
          Shugrue, DiGiorgio and Wischerth are  officers of each Trust.  C.
          Carl Randolph, a general partner of Neuberger&Berman, also  is an
          officer of each Trust.

               All of the outstanding voting stock in N&B Management is owned by
          persons who are also general partners of Neuberger&Berman.
    
          Sub-Adviser
   
               N&B Management  retains  Neuberger&Berman,  605 Third Avenue, New
          York, NY 10158, as a sub-adviser  with respect to each Series.  Except
          with  respect  to  the  International  Portfolio,  the  Sub-  Advisory
          Agreement was authorized by the Portfolios' predecessors' shareholders
          on August 25, 1994 and was approved by the holders of the interests in
          each  Series  on  April  13,  1994.  The  Sub-Advisory  Agreement  was
          authorized  by the  Trustees  of  Managers  Trust with  respect to AMT
          International Investments on November 30, 1995.

               The   Sub-Advisory   Agreement   provides   in   substance   that
          Neuberger&Berman  will  furnish  to  N&B  Management  such  investment
          recommendations  and  research  information,   of  the  same  type  as
          Neuberger&Berman  from  time  to time  provides  to its  partners  and
          employees  for use in  managing  client  accounts,  as N&B  Management
          reasonably  requests.  In this manner,  N&B Management expects to have
          available  to it, in  addition  to  research  from other  professional
          sources,  the  capability of the research  staff of  Neuberger&Berman.
          This research  staff  consists of  approximately  fourteen  investment
          analysts, each of whom specializes in studying one or more industries,
          under the supervision of research  partners who are also available for
          consultation with N&B Management.  The Sub-Advisory Agreement provides
          that the services rendered by Neuberger&Berman will be paid for by N&B
          Management  on  the  basis  of  the  direct  and  indirect   costs  to
          Neuberger&Berman  in connection with those services.  Neuberger&Berman
          also serves as a sub-adviser for all of the other mutual funds advised
          by N&B Management.
    
   
               The  Sub-Advisory  Agreement  continues until May 1, 1997, and is
          renewable  from year to year  thereafter,  subject to  approval of its
          continuance  in the  same  manner  as the  Management  Agreement.  The
          Sub-Advisory  Agreement is subject to  termination,  without  penalty,
          with  respect  to each  Series by the Series  Trustees,  by a 1940 Act
          majority vote of the outstanding Series shares, by N&B Management,  or
          by Neuberger&Berman on not less than 30 nor more than 60 days' written
          notice. The Sub-Advisory Agreement also terminates  automatically with
          respect  to  each  Series  if it is  assigned  or  if  the  Management
          Agreement terminates with respect to the Series.

               In addition,  Neuberger&Berman  serves as  investment  adviser to
          three investment companies, Plan Investment Fund, Inc., AHA Investment
          Fund,  Inc.,  and  AHA  Full  Maturity  with  assets  of  $77,883,200,
          $104,469,920, and $25,836,475, respectively, at February 29, 1996.
    
               The  investment  decisions  concerning  each Series and the other
          funds and  portfolios  referred  to above  (collectively,  "Other  N&B
          Funds") have been and will  continue to be made  independently  of one
          another.  In terms of their investment  objectives,  most of the Other
          N&B Funds differ from the Series. Even where the investment objectives
          are similar,  however, the methods used by the Other N&B Funds and the
          Series to achieve their objectives may differ.
   
               There may be occasions when a Series and one or more of the Other
          N&B Funds will be  contemporaneously  engaged in purchasing or selling
          the same  securities from or to third parties.  When this occurs,  the
          transactions  will be averaged as to price and allocated as to amounts
          in accordance  with a formula  considered to be equitable to the funds
          involved.  Although  in  some  cases  this  arrangement  could  have a
          detrimental  effect on the price or volume of the  securities  as to a
          Series,  in other  cases it is  believed  that a  Series's  ability to
          participate in volume  transactions may produce better  executions for
          it. In any case,  it is the judgment of the Series  Trustees  that the
          desirability of each Series having its advisory  arrangements with N&B
          Management   outweighs   any   disadvantages   that  may  result  from
          contemporaneous  transactions.  The investment results achieved by all
          of the funds  advised  by N&B  Management,  and  Neuberger&Berman  (as
          adviser and sub-adviser)  have varied from one another in the past and
          are likely to vary in the future.
    

                            DISTRIBUTION ARRANGEMENTS

               N&B  Management  serves  as the  distributor  ("Distributor")  in
          connection with the offering of each Portfolio's shares. In connection
          with  the  sale of its  shares,  each  Portfolio  has  authorized  the
          Distributor  to  give  only  the  information,  and to make  only  the
          statements and  representations,  contained in the Prospectus and this
          SAI  or  that  properly  may  be  included  in  sales  literature  and
          advertisements  in  accordance  with the 1933 Act,  the 1940 Act,  and
          applicable rules of self-regulatory  organizations.  Sales may be made
          only by the Prospectus,  which may be delivered  either  personally or
          through  the mails.  The  Distributor  is the  Portfolio's  "principal
          underwriter"  within the meaning of the 1940 Act and, as such, acts as
          agent in arranging  for the sale of each  Portfolio's  shares  without
          sales  commission or other  compensation and bears all advertising and
          promotion expenses incurred in the sale of the Portfolios' shares. The
          Board of Trustees of the Trust has adopted a non-fee Distribution Plan
          for each Portfolio of the Trust, which is described in the Prospectus.

               The Trust, on behalf of each  Portfolio,  and the Distributor are
          parties to a Distribution  Agreement dated May 1, 1995, that continues
          until May 1, 1997. The Distribution  Agreement may be renewed annually
          thereafter if  specifically  approved by (1) the vote of a majority of
          the Portfolio  Trustees or a 1940 Act majority vote of the Portfolio's
          outstanding  shares and (2) the vote of a majority of the  Independent
          Portfolio Trustees, cast in person at a meeting called for the purpose
          of  voting  on  such  approval.  The  Distribution  Agreement  may  be
          terminated  by either  party and will  automatically  terminate on its
          assignment,  in the same manner as the  Management  Agreement  and the
          Investment Advisory Agreement.


                        ADDITIONAL REDEMPTION INFORMATION

          Suspension of Redemptions

               The  Portfolios  are normally open for business each day the NYSE
          is open ("Business Day"). The right to redeem a Portfolio's shares may
          be suspended or payment of the redemption price postponed (1) when the
          NYSE is closed  (other than  weekend and holiday  closings),  (2) when
          trading on the NYSE is restricted,  (3) when an emergency  exists as a
          result of which disposal by the  Portfolio's  corresponding  Series of
          securities  owned  by it is not  reasonably  practicable  or it is not
          reasonably  practicable  for that Series fairly to determine the value
          of its net  assets,  or (4) for such  other  period  as the SEC may by
          order  permit  for  the  protection  of  a  Portfolio's  shareholders;
          provided that applicable SEC rules and regulations  shall govern as to
          whether the conditions prescribed in (2) or (3) exist. If the right of
          redemption is  suspended,  shareholders  may withdraw  their offers of
          redemption or they will receive payment at the NAV per share in effect
          at the close of business on the first  Business Day after  termination
          of the suspension.


                        DIVIDENDS AND OTHER DISTRIBUTIONS
   
               Each  Portfolio   distributes  to  its  shareholders   (primarily
          insurance company separate accounts and Qualified Plans) amounts equal
          to substantially all of its  proportionate  share of its corresponding
          Series' net  investment  income  (after  deducting  expenses  incurred
          directly by the  Portfolio),  net capital  gains (both  long-term  and
          short-term)  and,  with  respect to all  Portfolios  except the Liquid
          Asset   Portfolio,   net   realized   gains  from   foreign   currency
          transactions,  if any. Each  Portfolio  calculates  its net investment
          income and NAV as of the close of regular  trading on the NYSE on each
          Business  Day  (currently  4:00 p.m.  Eastern  time).  A  Series'  net
          investment  income consists of all income accrued on portfolio  assets
          less accrued  expenses;  realized  gains and losses are reflected in a
          Series' NAV (and, hence, its corresponding Portfolio's NAV) until they
          are  distributed and are not included in net investment  income.  With
          respect to the Government Income, Growth, Partners,  Balanced, Limited
          Maturity  Bond  and  International  Portfolios,   dividends  from  net
          investment  income and distributions of net realized capital gains and
          net  realized  gains  from  foreign  currency  transactions,  if  any,
          normally  are paid  once  annually,  in  February.  The  Liquid  Asset
          Portfolio  distributes to its  shareholders  substantially  all of its
          share of its  corresponding  Series' net investment income (net of the
          Portfolio's expenses) and net realized capital gains. Income dividends
          are declared daily for the Liquid Asset  Portfolio at the time its NAV
          is calculated and are paid monthly, and net realized capital gains, if
          any, are normally distributed annually in February.
    

                           ADDITIONAL TAX INFORMATION

          Taxation of the Portfolios

               In order to continue to qualify for  treatment as a RIC under the
          Internal  Revenue Code of 1986, as amended  ("Code"),  each  Portfolio
          must distribute to its shareholders for each taxable year at least 90%
          of its investment company taxable income (consisting  generally of net
          investment  income,  net short-term capital gain, and, with respect to
          all  Portfolios  except the  Liquid  Asset  Portfolio,  net gains from
          certain foreign currency  transactions)  ("Distribution  Requirement")
          and must meet several  additional  requirements.  With respect to each
          Portfolio, these requirements include the following: (1) the Portfolio
          must derive at least 90% of its gross  income each  taxable  year from
          dividends,  interest,  payments with respect to securities  loans, and
          gains  from the sale or other  disposition  of  securities  or foreign
          currencies,  or other income  (including gains from options,  futures,
          and forward contracts  (collectively,  "Hedging Instruments")) derived
          with  respect to its  business of  investing  in  securities  or those
          currencies ("Income Requirement");  (2) the Portfolio must derive less
          than 30% of its gross  income each taxable year from the sale or other
          disposition of securities, or any of the following, that were held for
          less than three  months - - Hedging  Instruments  (other than those on
          foreign  currencies),  or foreign  currencies (or Hedging  Instruments
          thereon) that are not directly  related to the  Portfolio's  principal
          business of  investing  in  securities  (or  options and futures  with
          respect thereto) ("Short-Short  Limitation");  and (3) at the close of
          each quarter of the Portfolio's  taxable year, (i) at least 50% of the
          value of its total assets must be  represented by cash and cash items,
          U.S. Government  securities,  and other securities limited, in respect
          of any one  issuer,  to an amount that does not exceed 5% of the value
          of the  Portfolio's  total assets and does not represent more than 10%
          of the issuer's outstanding voting securities,  and (ii) not more than
          25% of the value of its total  assets may be  invested  in  securities
          (other than U.S. Government securities) of any one issuer.
   
               The Trust and  Managers  Trust have  received  a ruling  from the
          Internal  Revenue  Service  ("Service")  that  each  Portfolio,  as an
          investor in a corresponding  Series of Managers Trust,  will be deemed
          to own a  proportionate  share of the  Series'  assets  and income for
          purposes  of   determining   whether  the   Portfolio   satisfies  the
          requirements described above to qualify as a RIC.
    
               See the next section for a discussion of the tax  consequences to
          the Portfolios of distributions  to them from the Series,  investments
          by the Series in certain securities,  and (except for AMT Liquid Asset
          Investments) hedging transactions engaged in by the Series.

          Taxation of the Series
   
               Managers  Trust has  received  a ruling  from the  Service to the
          effect  that,  among  other  things,  each Series will be treated as a
          separate partnership for federal income tax purposes and will not be a
          "publicly traded  partnership." As a result, no Series will be subject
          to federal income tax; instead,  each investor in a Series,  such as a
          Portfolio,  will be required to take into account in  determining  its
          federal income tax liability its share of the Series'  income,  gains,
          losses,  deductions,  and  credits,  without  regard to whether it has
          received any cash  distributions  from the Series.  A Series also will
          not be subject to Delaware or New York income or franchise tax.
    
               Because,  as noted above,  each Portfolio will be deemed to own a
          proportionate share of its corresponding Series' assets and income for
          purposes  of   determining   whether  the   Portfolio   satisfies  the
          requirements to qualify for treatment as a RIC, each Series intends to
          conduct its  operations so that its  corresponding  Portfolio  will be
          able to satisfy all those requirements.

               Distributions  to  a  Portfolio  from  its  corresponding  Series
          (whether  pursuant to a partial or complete  withdrawal  or otherwise)
          will not result in the Portfolio's recognition of any gain or loss for
          federal  income tax purposes,  except that (1) gain will be recognized
          to the extent any cash that is  distributed  exceeds  the  Portfolio's
          basis for its  interest  in the Series  before the  distribution,  (2)
          income  or  gain  will  be  recognized  if  the   distribution  is  in
          liquidation  of the  Portfolio's  entire  interest  in the  Series and
          includes a disproportionate  share of any unrealized  receivables held
          by  the  Series,   (3)  loss  will  be  recognized  if  a  liquidation
          distribution consists solely of cash and/or unrealized receivables and
          (4) gain (and,  in certain  situations,  loss) may be recognized on an
          in-kind  distribution by the Portfolios.  A Portfolio's  basis for its
          interest in its  corresponding  Series generally will equal the amount
          of cash and the basis of any  property  the  Portfolio  invests in the
          Series,  increased by the Portfolio's  share of the Series' net income
          and gains and decreased by (a) the amount of cash and the basis of any
          property  the  Series   distributes  to  the  Portfolio  and  (b)  the
          Portfolio's share of the Series' losses.
   
               Dividends, interest, and in some cases, capital gains received by
          a Series may be subject to income, withholding, or other taxes imposed
          by foreign countries and U.S.  possessions that would reduce the yield
          on its securities.  Tax conventions  between certain countries and the
          United States may reduce or eliminate these foreign taxes, however.
    
               AMT Balanced, Growth, Partners, and International Investments may
          invest  in  the  stock  of  "passive  foreign  investment   companies"
          ("PFICs").  A PFIC is a foreign  corporation  that, in general,  meets
          either of the following tests: (1) at least 75% of its gross income is
          passive or (2) an average  of at least 50% of its assets  produce,  or
          are  held  for  the  production  of,  passive  income.  Under  certain
          circumstances,  if a Series holds stock of a PFIC,  its  corresponding
          Portfolio  (indirectly  through its  interest  in the Series)  will be
          subject   to  federal   income  tax  on  a  portion  of  any   "excess
          distribution"  received on the stock as well as gain on disposition of
          the stock (collectively,  "PFIC income"),  plus interest thereon, even
          if the Portfolio  distributes the PFIC income as a taxable dividend to
          its  shareholders.  The balance of the PFIC income will be included in
          the Portfolio's  investment  company taxable income and,  accordingly,
          will not be taxable to it to the extent that income is  distributed to
          its shareholders.

               If a Series  invests  in a PFIC and elects to treat the PFIC as a
          "qualified   electing  fund,"  then  in  lieu  of  its   corresponding
          Portfolio's  incurring the foregoing tax and interest obligation,  the
          Portfolio  would be  required  to include in income  each year its pro
          rata share of the  Series'  pro rata share of the  qualified  electing
          fund's  annual  ordinary  earnings and net capital gain (the excess of
          net long-term capital gain over net short-term  capital loss) -- which
          most likely would have to be  distributed  by the Portfolio to satisfy
          the  Distribution  Requirement -- even if those earnings and gain were
          not  received  by the  Series.  In  most  instances  it  will  be very
          difficult, if not impossible, to make this election because of certain
          requirements thereof.

               The "Tax Simplification and Technical  Corrections Bill of 1993,"
          passed  in May  1994  by the  House  of  Representatives,  would  have
          substantially  modified the taxation of U.S.  shareholders  of foreign
          corporations,  including  eliminating  the provisions  described above
          dealing with PFICS and replacing  them (and other  provisions)  with a
          regulatory   scheme   involving   entities  called  "passive   foreign
          corporations." Three similar bills were passed by Congress in 1991 and
          1992 and vetoed. It is unclear at this time whether, and in what form,
          the proposed modifications may be enacted into law.
   
               Pursuant  to  proposed   regulations   that  are  not   currently
          effective, open-end RICs, such as the Portfolios, would be entitled to
          elect   to   "mark-to-market"    their   stock   in   certain   PFICs.
          "Marking-to-market,"  in this context,  means  recognizing as gain for
          each taxable year the excess,  as of the end of that year, of the fair
          market value of each such PFIC's stock over the adjusted basis in that
          stock (including  mark-to-market gain for each prior year for which an
          election was in effect).

               The use by the Series  (except AMT Liquid Asset  Investments)  of
          hedging  strategies,  such as writing (selling) and purchasing futures
          contracts  and options and entering into forward  contracts,  involves
          complex  rules  that  will  determine  for  income  tax  purposes  the
          character  and  timing of  recognition  of the gains and  losses  they
          realize  in  connection  therewith.  Income  from  foreign  currencies
          (except  certain  gains  therefrom  that  may be  excluded  by  future
          regulations),  and income  from  transactions  in Hedging  Instruments
          derived by a Series  with  respect to its  business  of  investing  in
          securities or foreign  currencies,  will qualify as permissible income
          for its corresponding Portfolio under the Income Requirement. However,
          income  from  the  disposition  by a Series  of  options  and  futures
          contracts  (generally other than those on foreign  currencies) will be
          subject to the Short-Short Limitation for its corresponding  Portfolio
          if they  are  held  for  less  than  three  months.  Income  from  the
          disposition of foreign currencies,  and Hedging  Instruments  thereon,
          that are not  directly  related  to a Series'  principal  business  of
          investing in securities (or options and futures with respect  thereto)
          also  will  be  subject  to  the  Short-  Short   Limitation  for  its
          corresponding Portfolio if they are held for less than three months.
    
               If a Series  (except  AMT  Liquid  Asset  Investments)  satisfies
          certain requirements, any increase in value of a position that is part
          of a  "designated  hedge"  will be  offset  by any  decrease  in value
          (whether  realized or not) of the offsetting  hedging  position during
          the  period of the hedge  for  purposes  of  determining  whether  its
          corresponding  Portfolio satisfies the Short-Short  Limitation.  Thus,
          only the net gain (if any) from the designated  hedge will be included
          in gross  income  for  purposes  of that  limitation.  A  Series  will
          consider  whether it should seek to qualify for this treatment for its
          hedging  transactions.  To the extent a Series does not so qualify, it
          may be forced to defer the closing out of certain Hedging  Instruments
          beyond the time when it otherwise  would be  advantageous to do so, in
          order for its corresponding Portfolio to continue to qualify as a RIC.
   
               Exchange-traded  futures  contracts  and listed  options  thereon
          constitute  "Section  1256  Contracts."  Section  1256  Contracts  are
          required  to be  "marked-to-market"  (that is,  treated as having been
          sold at  market  value) at the end of a Series'  taxable  year,  sixty
          percent of any gain or loss  recognized  as a result of these  "deemed
          sales,"  and 60% of any net  realized  gain or loss  from  any  actual
          sales, of Section 1256 contracts are treated as long-term capital gain
          or loss,  and the remainder is treated as  short-term  capital gain or
          loss;  however, in certain cases where the futures contract relates to
          a  foreign  currency,  the gain or loss may be  ordinary  rather  than
          capital.

               AMT Limited  Maturity  Bond  Investments  may invest in municipal
          bonds that are  purchased  with market  discount  (that is, at a price
          less than the bond's  principal  amount or, in the case of a bond that
          was issued with original issue discount ("OID"), a price less than the
          amount  of the  issue  price  plus  accrued  OID)  ("municipal  market
          discount bonds"). If a bond's market discount is less than the product
          of (1) 0.25% of the redemption  price at maturity times (2) the number
          of complete  years to maturity  after the taxpayer  acquired the bond,
          then  no  market  discount  is  considered  to  exist.   Gain  on  the
          disposition  of a municipal  market  discount  bond  purchased  by the
          Series  after April 30, 1993 (other than a bond with a fixed  maturity
          date  within  one year from its  issuance),  generally  is  treated as
          ordinary (taxable) income,  rather than capital gain, to the extent of
          the bond's accrued market discount at the time of disposition. In lieu
          of treating  the  disposition  gain as above,  the Series may elect to
          include  market  discount  in its  gross  income  currently,  for each
          taxable year to which it is  attributable.  Market  discount on such a
          bond generally is accrued ratably,  on a daily basis,  over the period
          from the acquisition date to the date of maturity.

               AMT Partners,  AMT Balanced and AMT Government Income Investments
          each may acquire zero coupon or other  securities  issued with OID. As
          the holder of those  securities,  each  Series  (and,  through it, its
          corresponding  Portfolio)  must take into account the OID that accrues
          on the securities  during the taxable year,  even if no  corresponding
          payment on the  securities is received  during the year.  Because each
          Portfolio  annually must  distribute  substantially  all of its income
          (including  its share of its  corresponding  Series'  accrued  OID) in
          order to satisfy the Distribution Requirement, it may be required in a
          particular  year to distribute as a dividend an amount that is greater
          than its share of the total  amount of cash its  corresponding  Series
          actually receives. Those distributions will be made from a Portfolio's
          (or its  share  of its  corresponding  Series')  cash  assets  or,  if
          necessary,  from  the  proceeds  of the  Series'  sales  of  portfolio
          securities.  These  actions  are  likely to  reduce  the  Series'  and
          Portfolios'  assets and may thereby  increase  its  expense  ratio and
          decrease  its rate of return.  A Series may realize  capital  gains or
          losses  from  those  sales,  which  would  increase  or  decrease  its
          corresponding  Series'  investment  company  taxable income and/or net
          capital  gain.  In  addition,  any such gains may be  realized  on the
          disposition of securities held for less than three months.  Because of
          the  Short-Short  Limitation,  any such gains  would  reduce a Series'
          ability to sell other securities or Hedging  Instruments held for less
          than three months that it might wish to sell in the ordinary course of
          its portfolio management.

               Rules  governing  the tax  aspects  of swap  agreements  are in a
          developing  stage  and are not  entirely  clear in  certain  respects.
          Accordingly,  while  AMT  Government  Income  Investments  intends  to
          account  for such  transactions  in a manner  the  Series  deems to be
          appropriate,  the  Internal  Revenue  Service  might not  accept  such
          treatment.  If it  did  not,  the  status  of  the  Government  Income
          Portfolio as a regulated  investment  company  might be affected.  The
          Series  and  Portfolio  intend to monitor  developments  in this area.
          Certain  requirements that must be met under the Code in order for the
          Government  Income  Portfolio  to  qualify as a  regulated  investment
          company  may limit the  extent  to which  the  Series  will be able to
          engage in swap agreements.
    

                        VALUATION OF PORTFOLIO SECURITIES

               The Liquid Asset Portfolio relies on Rule 2a-7 under the 1940 Act
          to use the  amortized  cost  method  of  valuation  to  stabilize  the
          purchase and redemption  price of its shares at $1.00 per share.  This
          method involves the corresponding  Series valuing portfolio securities
          at their  cost at the  time of  purchase  and  thereafter  assuming  a
          constant  amortization  (or  accretion) to maturity of any premium (or
          discount),  regardless of the impact of interest rate  fluctuations on
          the market value of the securities.  The Liquid Asset Series uses that
          valuation  method to try to enable its  corresponding  Portfolio to so
          stabilize those prices. Although the Portfolio's reliance on Rule 2a-7
          and the  Series'  use of  that  valuation  method  should  enable  the
          Portfolio,  under most  conditions,  to maintain a stable  $1.00 share
          price,  there  can be no  assurance  they  will be  able to do so.  An
          investment  in the  Liquid  Asset  Portfolio  is neither  insured  nor
          guaranteed by the U.S. Government.

               AMT International  Investments invests primarily in securities of
          foreign  issuers  which are  traded on foreign  exchanges  or in other
          foreign markets. Foreign securities may trade on days when the NYSE is
          closed,  such as Saturdays and U.S. national  holidays.  However,  the
          International  Portfolio's  net asset value ("NAV") will be determined
          only on the days  when the NYSE is open for  trading.  Therefore,  the
          International  Portfolio's NAV may be  significantly  affected by such
          foreign trading on days when  shareholders have no access to redeem or
          purchase shares of the Portfolio.
   
          Each Portfolio and its corresponding Series calculate their NAVs as of
          the close of regular trading on the NYSE, usually 4 p.m.
          Eastern Time.
    
                             PORTFOLIO TRANSACTIONS

          All Series (except AMT International Investments)
   
               Neuberger&Berman  acts as each Series's  principal  broker to the
          extent  a  broker  is  used in the  purchase  and  sale  of  portfolio
          securities and in connection  with the writing of covered call options
          on their  securities.  Transactions in portfolio  securities for which
          Neuberger&Berman  serves as broker will be effected in accordance with
          Rule 17e-1 under the 1940 Act.
    
                To  the  extent a broker  is not  used,  purchases  and sales of
          portfolio  securities  generally  are  transacted  with  the  issuers,
          underwriters,  or dealers serving as primary  market-makers  acting as
          principals  for the  securities on a net basis.  The Series usually do
          not pay brokerage  commissions for such purchases and sales.  Instead,
          the  price  paid  for  newly  issued  securities  usually  includes  a
          concession  or  discount  paid by the issuer to the  underwriter,  and
          transactions placed through dealers serving as market-makers reflect a
          spread  between  the bid and the asked  prices  from  which the dealer
          derives a profit.
   
               In  purchasing  and selling  portfolio  securities  other than as
          described above (for example,  in the secondary market),  each Series'
          policy is to seek best execution at the most favorable  prices through
          responsible broker-dealers and, in the case of agency transactions, at
          competitive  commission rates. In selecting  broker-dealers to execute
          transactions,  N&B  Management  considers such factors as the price of
          the security,  the rate of commission,  the size and difficulty of the
          order, the reliability,  integrity,  financial condition,  and general
          execution and operational  capabilities  of competing  broker-dealers,
          and may consider the brokerage  and research  services they provide to
          the Series or N&B Management.  Some of these research  services may be
          of value to N&B Management in advising its various clients  (including
          the Series) although not all of these services are necessarily used by
          N&B  Management in managing the Series.  Under certain  conditions,  a
          Series may pay higher  brokerage  commissions  in return for brokerage
          and research services, although no Series has a current arrangement to
          do so. In any case, each Series may effect principal transactions with
          a dealer who  furnishes  research  services,  designate  any dealer to
          receive  selling  concessions,  discounts,  or  other  allowances,  or
          otherwise deal with any dealer in connection  with the  acquisition of
          securities in underwritings.
    
          AMT International Investments
   
               Neuberger&Berman   may  act  as  broker  for  AMT   International
          Investments  in the purchase and sale of portfolio  securities  and in
          the purchase and sale of options, and for those services would receive
          brokerage commissions.
    
          All Series
   
               During the years ended  December  31,  1995,  1994 and 1993,  AMT
          Growth  Investments  (and the predecessor of the Growth  Portfolio for
          the period prior to May 1, 1995) paid total  brokerage  commissions of
          $721,943,  $410,537  and  $853,501  respectively,  of which  $466,157,
          $321,277  and  $707,176  respectively  were paid to  Neuberger&Berman.
          Transactions  in which that Series (and the  predecessor of the Growth
          Portfolio  for the period prior to May 1, 1995) used  Neuberger&Berman
          as broker  comprised  69.6% and 83.4%  respectively  of the  aggregate
          dollar amount of  transactions  involving the payment of  commissions,
          and  64.6%  and  78.3%   respectively   of  the  aggregate   brokerage
          commissions  paid by it during the years ended  December  31, 1995 and
          1994.  91.6% of the $255,776 paid to other brokers by that Series (and
          the predecessor of the Growth Portfolio for the period prior to May 1,
          1995)  during  the  year  ended   December   31,  1995   (representing
          commissions on transactions involving  approximately  $97,979,789) and
          87.1% of the $89,260 paid to other brokers by the  predecessor  of the
          Growth Portfolio during the year ended December 31, 1994 (representing
          commissions on transactions involving  approximately  $33,414,132) was
          directed to those brokers because of research  services they provided.
          During  the  year  ended  December  31,  1995,  that  Series  (and the
          predecessor  of the Growth  Portfolio  for the period  prior to May 1,
          1995)   acquired   securities   of  the   following   of  its  Regular
          Broker-Dealers   ("B/Ds"):  Bear  Stearns  &  Co.  Inc.,  Exxon  Asset
          Management,  Exxon Credit Corp.,  General  Electric Capital Corp., and
          Morgan  Stanley  & Co.  Inc.;  at that  date,  that  Series  held  the
          securities  of its Regular  B/Ds with an  aggregate  value as follows:
          $4,571,250, Bear, Stearns & Co. Inc.; and $8,465,625, Morgan Stanley &
          Co. Inc.

               During the years ended  December  31,  1995,  1994 and 1993,  AMT
          Balanced  Investments  (and the predecessor of the Balanced  Portfolio
          for the period prior to May 1, 1995) paid total brokerage  commissions
          of $218,734,  $135,836 and $228,483  respectively,  of which $154,773,
          $107,420  and  $190,263  respectively  were paid to  Neuberger&Berman.
          Transactions in which that Series (and the predecessor of the Balanced
          Portfolio  for the period prior to May 1, 1995) used  Neuberger&Berman
          as broker  comprised  75.1% and 82.9%  respectively  of the  aggregate
          dollar amount of  transactions  involving the payment of  commissions,
          70.8% and 79.1%  respectively of the aggregate  brokerage  commissions
          paid by it during the years ended December 31, 1995 and 1994. 91.1% of
          the $63,961 paid to other brokers by that Series (and the  predecessor
          of the Balanced  Portfolio for the period prior to May 1, 1995) during
          the  year  ended  December  31,  1995  (representing   commissions  on
          transactions  involving  approximately  $25,896,846)  and 85.5% of the
          $28,416  paid to other  brokers  by the  predecessor  of the  Balanced
          Portfolio  during  the year  ended  December  31,  1994  (representing
          commissions on transactions involving  approximately  $10,593,478) was
          directed to those brokers because of research  services they provided.
          During  the  year  ended  December  31,  1995,  the  Series  (and  the
          predecessor  of the Balanced  Portfolio for the period prior to May 1,
          1995) acquired  securities of the following of its Regular B/Ds: Bear,
          Stearns & Co.  Inc.,  Exxon Credit  Corp.,  General  Electric  Capital
          Corp.,  and Morgan Stanley & Co. Inc.; at that date,  that Series held
          the securities of its Regular B/Ds with an aggregate value as follows:

          Management  Co.;  $10,000,000,  General  Electric  Capital Corp.;  and
          $1,370,625, Morgan Stanley & Co. Inc.

               During the year ended  December 31, 1995 and the period March 22,
          1994 to December  31,  1994,  the AMT  Partners  Investments  (and the
          predecessor  of the Partners  Portfolio for the period prior to May 1,
          1995)  paid  total  brokerage  commissions  of  $457,962  and  $27,115
          respectively of which $307,520 and $26,321,  respectively were paid to
          Neuberger&Berman.   Transactions   in  which  that   Series  (and  the
          predecessor  of the Partners  Portfolio for the period prior to May 1,
          1995)  used  Neuberger&Berman  as  broker  comprised  68.5%  and 97.4%
          respectively of the aggregate dollar amount of transactions  involving
          the payment of  commissions,  and 67.2% and 97.1%  respectively of the
          aggregate  brokerage  commissions  paid by it  during  the year  ended
          December 31, 1995,  and the period ended  December 31, 1994.  96.0% of
          the $150,442 paid to other brokers by that Series (and the predecessor
          of the Partners Portfolio for the period prior to May 1, 1995) for the
          year ended December 31, 1995 (representing commissions on transactions
          involving  approximately  $75,234,281)  and  91.5% of the $794 paid to
          other brokers by the predecessor of the Partners  Portfolio during the
          period  ended   December  31,  1994   (representing   commissions   on
          transactions involving  approximately  $275,017) was directed to those
          brokers because of research services they provided.  During the period
          ended  December  31,  1995,  that Series (and the  predecessor  of the
          Partners  Portfolio  for the  period  prior to May 1,  1995)  acquired
          securities  of  the  following  of  its  Regular  B/Ds:   Exxon  Asset
          Management,  Exxon Credit Corp.,  General  Electric Capital Corp., and
          Salomon  Brothers  Inc.;  at that date,  that  Series held none of the
          securities of its Regular B/Ds.

               During  the year  ended  December  31,  1995,  AMT  Liquid  Asset
          Investments (and the predecessor of the Liquid Asset Portfolio for the
          period prior to May 1, 1995)  acquired  securities of the following of
          its Regular B/Ds: General Electric Capital Corp., Goldman Sachs & Co.,
          Morgan (J.P.)  Securities Inc., and First Chicago Capital Markets;  at
          that  date  that  Series  held  securities  of its  Regular  B/Ds with
          aggregate value as follows: $1,597,199, Morgan (J.P.) Securities Inc.;
          and $1,177,923, General Electric Capital Corp.

               During the year ended  December  31, 1995,  AMT Limited  Maturity
          Bond  Investments  (and the  predecessor of the Limited  Maturity Bond
          Portfolio for the period prior to May 1, 1995) acquired  securities of
          the following of its Regular B/Ds: Exxon Credit Corp.,  Morgan Stanley
          & Co. Inc.,  and Salomon  Brothers Inc.; at that date that Series held
          securities of none of its Regular B/Ds.

               During the year ended December 31, 1995,  AMT  Government  Income
          Investments  (and the predecessor of the Government  Income  Portfolio
          for the period prior to May 1, 1995)  acquired  securities  of none of
          its Regular B/Ds.
    
   
               Insofar as portfolio  transactions  of AMT  Partners  Investments
          result from active  management  of equity  securities,  and insofar as
          portfolio  transactions of AMT Growth  Investments result from seeking
          capital  appreciation by selling securities  whenever sales are deemed
          advisable without regard to the length of time the securities may have
          been held, it may be expected that the aggregate brokerage commissions
          paid by those Series to brokers (including  Neuberger&Berman  where it
          acts in that capacity) may be greater than if securities were selected
          solely on a long-term basis.

               Portfolio  securities are from time to time loaned by AMT Growth,
          Partners  and  International   Investments  to   Neuberger&Berman   in
          accordance  with the terms and  conditions  of an order  issued by the
          Securities and Exchange  Commission,  excepting such transactions from
          certain provisions of the 1940 Act which would otherwise prohibit such
          transactions,  subject to certain conditions.  Among the conditions of
          the order,  securities  loans made by each Series to  Neuberger&Berman
          must be fully secured by cash collateral. Under the order, the portion
          of the  income on cash  collateral  from  securities  loans  involving
          Neuberger&Berman which may be shared with that firm is determined with
          reference to the concurrent arrangements between  Neuberger&Berman and
          other  non-affiliated   lenders  with  which  it  engages  in  similar
          transactions.  In addition,  where Neuberger&Berman borrows securities
          from a Series in order to relend them to others,  Neuberger&Berman  is
          required to pay over to the  Series,  on a  quarterly  basis,  certain
          "excess earnings" that Neuberger&Berman otherwise has derived from the
          relending   of   securities    borrowed   from   the   Series.    When
          Neuberger&Berman  desires  to  borrow a  security  which a Series  has
          indicated a  willingness  to lend,  Neuberger&Berman  must borrow such
          security  from the  Series  rather  than from an  unaffiliated  lender
          unless an unaffiliated lender is willing to lend such security on more
          favorable  terms (as  specified  in the order) than the  Series.  If a
          Series'  expenses exceed its income in any securities loan transaction
          with  Neuberger&Berman,  Neuberger&Berman must reimburse the Portfolio
          for such loss.
    
               Each Series may also lend  securities to  unaffiliated  entities,
          including brokers or dealers, banks and other recognized institutional
          borrowers of securities,  provided that cash or equivalent collateral,
          equal to at least 100% of the market value of the  securities  loaned,
          is continuously maintained by the borrower with the Series. During the
          time  securities  are on loan,  the  borrower  will pay the  Series an
          amount   equivalent   to  any  dividends  or  interest  paid  on  such
          securities,  and the Series may  invest the cash  collateral  and earn
          income,  or it may receive an agreed  upon  amount of interest  income
          from the borrower who has delivered equivalent collateral. These loans
          are  subject  to  termination  at  the  option  of the  Series  or the
          borrower.  The Series may pay reasonable  administrative and custodial
          fees in connection with a loan and may pay a negotiated portion of the
          interest  earned on the cash or equivalent  collateral to the borrower
          or  placing  broker.  The  Series  does  not  have  the  right to vote
          securities on loan, but would  terminate the loan and regain the right
          to  vote  if  that  were  considered  important  with  respect  to the
          investment.
   
               In effecting securities transactions, each Series generally seeks
          to obtain the best price and  execution of orders.  Commission  rates,
          being a component of price,  are considered  along with other relevant
          factors.  Each Series may use Neuberger&Berman as broker where, in the
          judgment   of   N&B    Management,    (which   is   affiliated    with
          Neuberger&Berman), the firm is able to obtain a price and execution at
          least  as  favorable  as  other  qualified  brokers.  To  the  Series'
          knowledge,  however,  no affiliate of any Series receives  give-ups or
          reciprocal  business in connection  with its securities  transactions.
          All  brokerage   transactions  with  Neuberger&Berman  (or  any  other
          affiliated  broker-dealer)  will be conducted in accordance  with Rule
          17e-1 under the 1940 Act.

               The use of  Neuberger&Berman  as a broker for a Series is subject
          to the requirements of Section 11(a) of the Securities Exchange Act of
          1934 ("Section  11(a)").  Section 11(a) prohibits  members of national
          securities exchanges from executing exchange transactions for accounts
          which they or their affiliates manage, except in situations where they
          have obtained the express  authorization of the persons  authorized to
          transact  business  for the  account and comply  with  certain  annual
          reporting  requirements.  The  Board of  Trustees  of the  Series  has
          expressly authorized Neuberger&Berman to execute exchange transactions
          for the  Series,  and  Neuberger&Berman  complies  with the  reporting
          requirements of Section 11(a).

               Under   the  1940   Act,   commissions   paid  by  a  Series   to
          Neuberger&Berman  in connection  with a purchase or sale of securities
          offered  on a  securities  exchange  may  not  exceed  the  usual  and
          customary broker's commission.  Accordingly, it is each Series' policy
          that  the  commissions  to be paid to  Neuberger&Berman  must,  in N&B
          Management's judgment be (1) at least as favorable as those that would
          be charged by other brokers having comparable execution capability and
          (2) at least as favorable as commissions  contemporaneously charged by
          Neuberger&Berman  on  comparable  transactions  for its  most  favored
          unaffiliated customers, except for accounts for which Neuberger&Berman
          acts as a clearing broker for another  brokerage firm and customers of
          Neuberger&Berman  considered by a majority of the  Independent  Series
          Trustees not to be comparable to the Series. The Series do not deem it
          practicable and in their best interest to solicit competitive bids for
          commissions on each transaction.  However,  consideration regularly is
          given to information  concerning  the prevailing  level of commissions
          charged on comparable  transactions by other brokers during comparable
          periods of time.  The 1940 Act  generally  prohibits  Neuberger&Berman
          from acting as principal in the purchase or sale of  securities  for a
          Series's account, unless an appropriate exemption is available.

               A committee  of  Independent  Series  Trustees  from time to time
          reviews,  among other things,  information relating to the commissions
          charged by  Neuberger&Berman  to the Series and to its other customers
          and information concerning the prevailing level of commissions charged
          by other brokers having comparable execution capability.  In addition,
          the procedures  pursuant to which  Neuberger&Berman  effects brokerage
          transactions  for the Series  must be  reviewed  and  approved no less
          often than annually by a majority of the Independent Series Trustees.

               Each Series expects that it will continue to execute a portion of
          its  transactions  through  brokers  other than  Neuberger&Berman.  In
          selecting those brokers,  N&B Management will consider the quality and
          reliability of brokerage services,  including execution capability and
          performance  and  financial  responsibility,   and  may  consider  the
          research and other investment  information  provided by those brokers,
          and  the  willingness  of  particular  brokers  to sell  the  Variable
          Contracts issued by the Life Companies.

               A committee, comprised of N&B Management officers and partners of
          Neuberger&Berman  who are portfolio managers of some of the Series and
          Other   N&B   Funds   (collectively,   "N&B   Funds")   and   some  of
          Neuberger&Berman's  managed accounts  ("Managed  Accounts")  evaluates
          semi-annually  the nature and quality of the  brokerage  and  research
          services  provided by other  brokers  and,  based on this  evaluation,
          establishes a list and projected  ranking of preferred brokers for use
          in determining the relative  amounts of commissions to be allocated to
          those  brokers.  Ordinarily  the  brokers  on the list  effect a large
          portion  of the  brokerage  transactions  for  the N&B  Funds  and the
          Managed Accounts that are not effected by  Neuberger&Berman.  However,
          in any  semi-annual  period,  brokers not on the list may be used, and
          the relative  amounts of brokerage  commissions paid to the brokers on
          the list may vary  substantially  from the projected  rankings.  These
          variations  reflect the following  factors,  among others: (1) brokers
          not on the list or  ranking  below  other  brokers  on the list may be
          selected for particular transactions because they provide better price
          and/or  execution,  which is the primary  consideration  in allocating
          brokerage;  and (2)  adjustments  may be required  because of periodic
          changes  in the  execution  or  research  capabilities  of  particular
          brokers, or in the execution or research needs of the N&B Funds and/or
          the  Managed  Accounts;  and (3) the  aggregate  amount  of  brokerage
          commissions  generated  by  transactions  for  the N&B  Funds  and the
          Managed Accounts may change  substantially from one semi-annual period
          to the next.

               The commissions  charged by a broker other than  Neuberger&Berman
          may be  greater  than the  amount  another  firm  might  charge if N&B
          Management   determines  in  good  faith  that  the  amount  of  those
          commissions  is  reasonable  in relation to the value of the brokerage
          and research services provided by the broker. N&B Management  believes
          that those  research  services  provide  the Series  with  benefits by
          supplementing the research otherwise  available to them. That research
          information  may be used by  Neuberger&Berman  and N&B  Management  in
          servicing   their   respective   funds   and,   in  some   cases,   by
          Neuberger&Berman in servicing the Managed Accounts. On the other hand,
          research information received by N&B Management from brokers effecting
          portfolio  transactions  on  behalf  of the  Other  N&B  Funds  and by
          Neuberger&Berman  from brokers  executing  portfolio  transactions  on
          behalf of the Managed Accounts may be used for the Series' benefit.

               Theresa A. Havell,  Mark R. Goldstein and Michael M. Kassen, each
          of whom is a general partner of Neuberger&Berman  and a Vice President
          of N&B Management (and, with respect to Ms. Havell, also a director of
          N&B  Management),  Josephine  P.  Mahaney,  Thomas  Wolfe and  William
          Cunningham, each of whom is an employee of Neuberger&Berman and a Vice
          President  of N&B  Management,  and  Robert  I.  Gendelman,  who is an
          employee of  Neuberger&Berman  and an Assistant  Vice President of N&B
          Management, are the persons primarily responsible for making decisions
          as to  specific  action to be taken  with  respect  to the  investment
          portfolios of the Series (except AMT International Investments).  Each
          of them has full  authority  to take action with  respect to portfolio
          transactions  and may or may not consult  with other  personnel of N&B
          Management prior to taking such action.

               Felix Rovelli, a Vice President of N&B Management,  is the person
          primarily responsible for making decisions as to specific action to be
          taken with respect to the AMT International  Investments.  He has full
          authority to take action with respect to  portfolio  transactions  and
          may or may not consult with other personnel of N&B Management prior to
          taking  such  action.  If Mr.  Rovelli is  unavailable  to perform his
          responsibilities, Robert Cresci, who is an Assistant Vice President of
          N&B Management,  will assume  responsibility  for the portfolio of AMT
          International Investments.
    
          Portfolio Turnover

               The  portfolio  turnover  rate is the  lesser  of the cost of the
          securities  purchased or the value of the securities  sold,  excluding
          all securities,  including options,  whose maturity or expiration date
          at the  time of  acquisition  was one  year or  less,  divided  by the
          average monthly value of such securities owned during the year.


                             REPORTS TO SHAREHOLDERS

               Shareholders  of each  Portfolio  receive  unaudited  semi-annual
          financial statements, as well as year-end financial statements audited
          by  the   independent   auditors  for  the   Portfolio   and  for  its
          corresponding  Series.  Each Portfolio's  report shows the investments
          owned by its  corresponding  Series and the market values  thereof and
          provides other information about the Portfolio and its operations.  In
          addition,  the report contains the Portfolio's  financial  statements,
          including the  Portfolio's  beneficial  interest in its  corresponding
          Series.


                                    CUSTODIAN

               Each  Portfolio  and Series has  selected  State  Street Bank and
          Trust  Company  ("State   Street"),   225  Franklin  Street,   Boston,
          Massachusetts 02110 as custodian for its securities and cash.


                              INDEPENDENT AUDITORS
   
               Each  Portfolio  and Series has  selected  Ernst & Young LLP, 200
          Clarendon  Street,  Boston,  MA 02116 as the independent  auditors who
          will audit its financial statements.
    

                                  LEGAL COUNSEL
   
               Each  Portfolio  and Series has selected  Dechert Price & Rhoads,
          1500 K  Street,  N.W.,  Suite  500,  Washington,  D.C.  20005 as legal
          counsel.

                              RATINGS OF SECURITIES

          S&P corporate bond ratings:

               AAA - Bonds  rated AAA have the highest  rating  assigned by S&P.
          Capacity to pay interest and repay principal is extremely strong.

               AA - Bonds rated AA have a very strong  capacity to pay  interest
          and repay  principal  and differ from the higher  rated issues only in
          small degree.

               A - Bonds  rated A have a strong  capacity  to pay  interest  and
          repay  principal,  although they are somewhat more  susceptible to the
          adverse effects of changes in  circumstances  and economic  conditions
          than bonds in higher rated categories.

               BBB - Bonds rated BBB are regarded as having an adequate capacity
          to pay principal and interest.  Whereas they normally exhibit adequate
          protection   parameters,   adverse  economic  conditions  or  changing
          circumstances  are more  likely to lead to a weakened  capacity to pay
          principal  and interest for bonds in this  category  than for bonds in
          higher rated categories.

               BB,  B, CCC,  CC, C - Bonds  rated  BB,  B,  CCC,  CC,  and C are
          regarded,  on balance,  as  predominantly  speculative with respect to
          capacity to pay interest and repay  principal in  accordance  with the
          terms of the obligation. BB indicates the lowest degree of speculation
          and C the highest degree of speculation.  While such bonds will likely
          have some quality and protective characteristics, these are outweighed
          by large uncertainties or major risk exposures to adverse conditions.

               CI - The  rating  CI is  reserved  for  income  bonds on which no
          interest is being paid.

               D - Bonds rated D are in default,  and payment of interest and/or
          repayment of principal is in arrears.

               Plus (+) or Minus (-) - The ratings  above may be modified by the
          addition of a plus or minus sign to show relative  standing within the
          major categories.

          Moody's corporate bond ratings

               Aaa - Bonds rated Aaa are judged to be of the best quality.  They
          carry  the  smallest  degree  of  investment  risk  and are  generally
          referred to as "gilt edge." Interest payments are protected by a large
          or an exceptionally  stable margin, and principal is secure.  Although
          the various protective elements are likely to change, the changes that
          can be visualized are most unlikely to impair the fundamentally strong
          position of the issuer.

               Aa - Bonds  rated  Aa are  judged  to be of high  quality  by all
          standards.  Together  with  the Aaa  group,  they  comprise  what  are
          generally  known as "high grade  bonds." They are rated lower than the
          best bonds  because  margins of  protection  may not be as large as in
          Aaa-rated  securities,  fluctuation  of protective  elements may be of
          greater  amplitude,  or there may be other elements  present that make
          the  long-term   risks  appear   somewhat  larger  than  in  Aaa-rated
          securities.

               A - Bonds rated A possess many  favorable  investment  attributes
          and are to be  considered as upper medium grade  obligations.  Factors
          giving security to principal and interest are considered adequate, but
          elements may be present that suggest a  susceptibility  to  impairment
          sometime in the future.

               Baa - Bonds which are rated Baa are  considered  as medium  grade
          obligations;  i.e.,  they are  neither  highly  protected  nor  poorly
          secured.  Interest payments and principal security appear adequate for
          the present but certain  protective  elements may be lacking or may be
          characteristically  unreliable  over any great  length of time.  These
          bonds lack  outstanding  investment  characteristics  and in fact have
          speculative characteristics as well.

               Ba - Bonds  rated Ba are  judged  to have  speculative  elements;
          their  future  cannot  be  considered  as  well  assured.   Often  the
          protection of interest and principal payments may be very moderate and
          thereby not well  safeguarded  during both good and bad times over the
          future. Uncertainty of position characterizes bonds in this class.

               B - Bonds rated B generally lack characteristics of the desirable
          investment.  Assurance  of  interest  and  principal  payments  or  of
          maintenance  of other terms of the contract  over any long period time
          may be small.

               Caa - Bonds rated Caa are of poor standing. Such issues may be in
          default or there may be present  elements  of danger  with  respect to
          principal or interest.

               Ca - Bonds rated Ca represent obligations that are speculative in
          a high  degree.  Such issues are often in default or have other marked
          shortcomings.

               C - Bonds rated C are the lowest rated class of bonds, and issues
          so rated can be regarded as having  extremely  poor  prospects of ever
          attaining any real investment standing.

               Modifiers - Moody's may apply numerical  modifiers 1, 2, and 3 in
          each generic rating  classification  described  above.  The modifier 1
          indicates  that the  security  ranks in the higher end of its  generic
          rating category; the modifier 2 indicates a mid-range ranking; and the
          modifier 3  indicates  that the  issuer  ranks in the lower end of its
          generic rating category.

          S&P commercial paper ratings

               A-1 - This highest  category  indicates that the degree of safety
          regarding timely payment is strong. Those issues determined to possess
          extremely strong safety  characteristics  are denoted with a plus sign
          (+).

          Moody's commercial paper ratings

               Issuers rated Prime-1 (or related supporting institutions),  also
          known as P-1,  have a superior  capacity for  repayment of  short-term
          promissory  obligations.  Prime-1 repayment  capacity will normally be
          evidenced by the following characteristics:

               -Leading market positions in well-established industries.

               -High rates of return on funds employed.

               -Conservative capitalization structures with moderate reliance on
               debt and ample asset protection.

               -Broad margins in earnings  coverage of fixed  financial  charges
               and high internal cash generation.

               -Well-established access to a range of financial markets and
               assured sources   of alternate liquidity.

                         During my more  than  sixty-five  years of  buying  and
                    selling securities,  I've been asked many questions about my
                    approach  to  investing.  On the  pages  that  follow  are a
                    variety  of my  thoughts,  ideas and  investment  principles
                    which have served me well over the years. If you gain useful
                    knowledge in the pursuit of profit as well as enjoyment from
                    these comments, I shall be more than content.

                      YOU'VE BEEN ABLE TO
                      CONDENSE SOME OF THE
                      CHARACTERISTICS OF
                      SUCCESSFUL INVESTING INTO
                      FIVE "RULES."  WHAT ARE
                      THEY?

                      Rule  #1:  Be  flexible.  My  philosophy  has  necessarily
                      changed from time to time because of events and because of
                      mistakes.  My views  change as  economic,  political,  and
                      technological  changes occur both on and sometimes off our
                      planet.  It is  imperative  that you be  willing to change
                      your thoughts to meet new conditions.

                      Rule #2: Take your
                      temperament into account.
                      Recognize whether you are
                      by nature very speculative
                      or just the opposite -
                      fearful, timid of taking
                      risks. But in any event --

    Diversify your    Rule #3: Be broad-gauged.
    investments,      Diversify your investments,
    make sure that    make sure that some of your
    some of your      principal is kept safe, and
    principal is      try to increase your income
    kept safe, and    as well as your capital.

    your income as
    well as your
    capital.           [PICTURE OF ROY NEUBERGER]

                      Rule #4:  Always  remember  there  are many ways to skin a
                      cat!  Ben Graham  and David  Dodd did it by  understanding
                      basic values.  Warren  Buffet  invested his portfolio in a
                      handful of long-term holdings, while staying involved with
                      the   companies'   managements.   Peter   Lynch  chose  to
                      understand,  first-hand,  the products of many hundreds of
                      the  companies  he invested  in.  George  Soros showed his
                      genius as a hedge fund investor who could  decipher  world
                      currency trends.  Each has been successful in his own way.
                      But to be successful, remember to


                      Rule #5: Be skeptical. To
                      repeat a few well-worn
                      useful phrases:

                           A. Dig for yourself.
                           B. Be from Missouri.
                           C. If it sounds too
                           good to be true, it
                           probably is.

                      IN YOUR 65  YEARS  OF  INVESTING  ARE  THERE  ANY  GENERAL
                      PATTERNS YOU'VE OBSERVED AS TO HOW THE MARKET BEHAVES?

                      Every decade that I've been  involved with Wall Street has
                      a nuance of its own, an economic  and social  climate that
                      influences investors. But generally,  bull markets tend to
                      be longer than bear  markets,  and stock prices tend to go
                      up more  slowly and  erratically  than they go down.  Bear
                      markets tend to be shorter and of greater  intensity.  The
                      market rarely rises or declines concurrently with business
                      cycles longer than six months.


                      AS A LEGENDARY "VALUE
                      INVESTOR," HOW DO YOU
                      DEFINE VALUE INVESTING?

                      Value  investing  means  finding the best values -- either
                      absolute  or  relative.  Absolute  means a stock has a low
                      market price  relative to its own  fundamentals.  Relative
                      value means the price is attractive relative to the market
                      as a whole.

                      COULD YOU DESCRIBE A STOCK
                      WITH "GOOD VALUE"?

                      A classic  example  is a  company  that has a low price to
                      earnings ratio, a low price to book ratio, free cash flow,
                      a strong  balance  sheet,  undervalued  corporate  assets,
                      unrecognized  earnings  turnaround  and  is  selling  at a
                      discount to private market value.

                      These  characteristics  usually lead to companies that are
                      under-researched   and  have  a  high   degree  of  inside
                      ownership and entrepreneurial management.

                      One of my colleagues at Neuberger&Berman says he finds his
                      value  stocks  either  "under a cloud"  or "under a rock."
                      "Under a cloud"  stocks are those  Wall  Street in general
                      doesn't like,  because an entire  industry is out of favor
                      and even the good stocks are being dropped. "Under a rock"
                      stocks are those Wall Street is  ignoring,  so you have to
                      uncover them on your own.

                      ARE THERE OTHER KEY
                      CRITERIA YOU USE TO JUDGE
                      STOCKS?

                      I'm more interested in longer-term trends in earnings than
                      short-term trends. Earnings gains should be the product of
                      long-term   strategies,    superior   management,   taking
                      advantage  of business  opportunities  and so on. If these
                      factors are in their  proper  place,  short-term  earnings
                      should not be of major concern. Dividends are an important
                      extra because,  if they're  stable,  they help support the
                      price of the stock.

                      WHAT ABOUT SELLING STOCKS?

                      Most individual  investors should invest for the long term
                      but not mindlessly. A sell discipline,  often neglected by
                      investors, is vitally important.

    "One should fall  One should fall in love
    in love with      with ideas, with people, or
    ideas, with       with idealism.  But in my
    people or with    book, the last thing to
    idealism.  But    fall in love with is a
    in my book, the   particular security. It is
    last thing to     after all just a sheet of
    fall in love      paper indicating a part
    with is a         ownership in a corporation
    particular        and its use is purely
    security."        mercenary.  If you must
                      love a  security,  stay in  love  with  it  until  it gets
                      overvalued; then let somebody else fall in love.



                      [PICTURE OF ROY NEUBERGER]

                      ANY OTHER ADVICE FOR
                      INVESTORS?

                      I  firmly  believe  that if you  want to  manage  your own
                      money,  you must be a  student  of the  market.  If you're
                      unwilling  or  unable  to do that,  find  someone  else to
                      manage your money for you. Two options are a  well-managed
                      no-load  mutual  fund or, if you have  enough  assets  for
                      separate  account  management,  a money  manager you trust
                      with a good record.

                      HOW WOULD YOU DESCRIBE YOUR
                      PERSONAL INVESTING STYLE?

                      Every  stock I buy is bought to be sold.  The  market is a
                      daily event, and I continually  review my holdings looking
                      for selling opportunities. I take a profit occasionally on
                      something that has gone up in price over what was expected
                      and simultaneously take losses whenever  misjudgment seems
                      evident. This creates a reservoir of buying power that can
                      be used to  make  fresh  judgments  on what  are the  best
                      values in the  market at that  time.  My active  investing
                      style has worked well for me over the years,  but for most
                      investors I recommend a longer-term approach.

                      I tend not to worry  very must about the day to day swings
                      of the market, which are very hard to comprehend. Instead,
                      I try to be rather clever in diagnosing  values and trying
                      to win 70 to 80 percent of the time.

                      YOU BEGAN INVESTING IN
                      1929.  WHAT WAS YOUR
                      EXPERIENCE WITH THE "GREAT
                      CRASH"?

                      The only  money I managed in the Panic of 1929 was my own.
                      My  portfolio  was  down  about 12  percent,  and I had an
                      uneasy feeling about the market and conditions in general.
                      Those were the days of 10 percent  margin.  I studied  the
                      lists  carefully  for a stock  that was  overvalued  in my
                      opinion  and which I could sell  short as a hedge.  I came
                      across RCA at about $100 per share.  It had recently split
                      5 for 1 and appeared overvalued.  There were no dividends,
                      little  income,  a low  net  worth  and a  weak  financial
                      position.  I sold  RCA  short in the  amount  equal to the
                      dollar  value  of my long  portfolio.  It  proved  to be a
                      timely and profitable move.

                      HOW DID THE CRASH OF 1929
                      AFFECT YOUR INVESTING
                      STYLE?

                      I am  prematurely  bearish  when the market  goes up for a
                      long time and  everybody is happy because they are richer.
                      I  am  very   bullish   when  the  market  has  gone  down
                      perceptibly  and I feel it has  discounted any troubles we
                      are going to have.

                      HOW IMPORTANT ARE
                      PSYCHOLOGICAL FACTORS TO
                      MARKET BEHAVIOR?

                      There are many factors in addition to economic  statistics
                      or security analysis in a buy or sell decision.  I believe
                      psychology  plays an  important  role in the Market.  Some
                      people follow the crowd in hopes they'll be swept along in
                      the right  direction,  but if the crowd is late in acting,
                      this can be a bad move.

                      I like to be  contrary.  When  things  look bad,  I become
                      optimistic.  When everything  looks rosy, and the crowd is
                      optimistic,  I like  to be a  seller.  Sometimes  I'm  too
                      early, but I generally profit.

                      AS A  RENOWNED  ART  COLLECTOR,  DO YOU FIND  SIMILARITIES
                      BETWEEN SELECTING STOCKS AND SELECTING WORKS OF ART?

                      Both are an art, although
                      picking stocks is a minor
    "When things      art compared with painting,
    look bad, I       sculpture or literature.  I
    become            started buying art in the

    When everything   a daily, almost hourly
    looks rosy, and   occurrence.  My inclination
    the crowd is      to buy the works of living

    seller."          painting during his
                      lifetime.  He died in
                      poverty, only then to
                      become a legend and have
                      his work sold for millions
                      of dollars.

                      There are more  variables  to consider  now in both buying
                      art and picking stocks.  In the modern stock markets,  the
                      heavy use of futures and options has changed the nature of
                      the investment  world. In past times, the stock market was
                      much less complicated, as was the art world.

                      Artists rose and fell on their own merits without a lot of
                      publicity  and  attention.  As more and more  dealers  are
                      involved  with  artists,  the price of their work  becomes
                      inflated.  So  I  almost  always  buy  works  of  unknown,
                      relatively  undiscovered  artists,  which,  I  suppose  is
                      similar to value  investing.  But the big difference in my
                      view of art and  stocks  is that I buy a stock  to sell it
                      and make money. I never bought paintings or sculptures for
                      investment  in my life.  The  objective  is to enjoy their
                      beauty.

                      WHAT DO YOU CONSIDER THE
                      BUSINESS MILESTONES IN YOUR
                      LIFE?

                      Being a founder of  Neuberger&Berman  and  creating one of
                      the first no-load  mutual funds.  I started on Wall Street
                      in 1929,  and during the depression I managed my own money
                      and that of my clientele.  We all prospered,  but I wanted
                      to have  my own  firm.  In  1939 I  became  a  founder  of
                      Neuberger&Berman,  and for about 10 years we managed money
                      for individuals with substantial  financial assets.  But I
                      also wanted to offer the smaller  investor the benefits of
                      professional  money  management,  so in 1950 I created the
                      Guardian  Mutual  Fund (now known as the  Neuberger&Berman
                      Guardian Fund).  The Fund was kind of an innovation in its
                      time  because  it  didn't  charge  a sales  commission.  I
                      thought the public was being overcharged for mutual funds,
                      so I  wanted  to  create  a fund  that  would  be  offered
                      directly  to the  public  without a sales  charge.  Now of
                      course the "no-load" fund business is a huge  industry.  I
                      managed the Fund myself for over 28 years.

                      YOU'RE IN YOUR  NINETIES  AND STILL YOU GO INTO THE OFFICE
                      EVERY DAY TO MANAGE YOUR INVESTMENTS. WHY?

                      I like the fun of being  nimble in the stock  market,  and
                      I'm addicted to the market's fascinations.

                      WHAT CLOSING WORDS OF
                      ADVICE DO YOU HAVE ABOUT
                      INVESTING?

                      Realize that there are  opportunities at all times for the
                      adventuresome   investor.   And  stay  in  good   physical
                      condition. It's a strange thing. You do not dissipate your
                      energies by using them.  Exercise your body and your brain
                      every  day,  and  you'll do better in  investments  and in
                      life.

                      ROY NEUBERGER:  A BRIEF
                      BIOGRAPHY

                      Roy  Neuberger is a founder of the  investment  management
                      firm  Neuberger&Berman,  and a renowned value investor. He
                      is also a recognized  collector of  contemporary  American
                      art,  much of  which  he has  given  away to  museums  and
                      colleges across the country.

                           During the 1920s,  Roy studied art in Paris.  When he
                      realized he didn't possess the talent to become an artist,
                      he decided to collect art,  and to support  this  passion,
                      Roy turned to investing -- a pursuit for which his talents
                      have proven more than adequate.

                      A TALENT FOR INVESTING

                           Roy  began  his   investment   career  by  joining  a
                      brokerage  firm in 1929,  seven  months  before the "Great
                      Crash." Just weeks before  "Black  Monday," he shorted the
                      stock of RCA, thinking it was overvalued. He profited from
                      the  falling  market  and gained a  reputation  for market
                      prescience and stock  selection that has lasted his entire
                      career.

                      NEUBERGER&BERMAN'S FOUNDING

                           Roy's  investing  acumen  attracted  many  people who
                      wished to have him manage their money. In 1939, at the age
                      of 36,  after  purchasing  a seat  on the New  York  Stock
                      Exchange,  Roy founded  Neuberger&Berman  to provide money
                      management   services  to  people  who  lacked  the  time,
                      interest or expertise to manage their own assets.

                      NEUBERGER&BERMAN -- OVER
                      FIVE DECADES OF GROWTH

                           Neuberger&Berman  has grown through the years and now
                      manages  approximately  $30  billion  of equity  and fixed
                      income  assets,  both  domestic  and  international,   for
                      individuals,  institutions,  and  its  family  of  no-load
                      mutual  funds.  Today,  as  when  the  firm  was  founded,
                      Neuberger&Berman  follows a value  approach to  investing,
                      designed to enable  clients to advance in good markets and
                      minimize losses when conditions are less favorable.

Item 27.          Indemnification

                  A Delaware business trust may provide in its governing
instrument for indemnification of its officers and trustees from and against any
and all claims and demands whatsoever. Article IX, Section 2 of the Trust
Instrument provides that the Registrant shall indemnify any present or former
trustee, officer, employee or agent of the Registrant ("Covered Person") to the
fullest extent permitted by law against liability and all expenses reasonably
incurred or paid by him in connection with any claim, action, suit or proceeding
("Action") in which he becomes involved as a party or otherwise by virtue of his
being or having been a Covered Person and against amounts paid or incurred by


<PAGE>


PART C - Other Information
Page 5


him in settlement thereof. Indemnification will not be provided to a person
adjudged by a court or other body to be liable to the Registrant or its
shareholders by reason of "willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of his office"
("Disabling Conduct"), or not to have acted in good faith in the reasonable
belief that his action was in the best interest of the Registrant. In the event
of a settlement, no indemnification may be provided unless there has been a
determination that the officer or trustee did not engage in Disabling Conduct
(i) by the court or other body approving the settlement; (ii) by at least a
majority of those trustees who are neither interested persons, as that term is
defined in the Investment Company Act of 1940, of the Registrant ("Independent
Trustees"), nor are parties to the matter based upon a review of readily
available facts; or (iii) by written opinion of independent legal counsel based
upon a review of readily available facts.

                  Pursuant to Article IX, Section 3 of the Trust Instrument, if
any present or former shareholder of any series ("Series") of the Registrant
shall be held personally liable solely by reason of his being or having been a
shareholder and not because of his acts or omissions or for some other reason,
the present or former shareholder (or his heirs, executors, administrators or
other legal representatives or in the case of any entity, its general successor)
shall be entitled out of the assets belonging to the applicable Series to be
held harmless from and indemnified against all loss and expense arising from
such liability. The Registrant, on behalf of the affected Series, shall, upon
request by such shareholder, assume the defense of any claim made against such
shareholder for any act or obligation of the Series and satisfy any judgment
thereon from the assets of the Series.

                  Section 9 of the Management Agreement between Advisers
Managers Trust and Neuberger & Berman Management Incorporated ("N&B Management")
provides that neither N&B Management nor any director, officer or employee of
N&B Management performing services for any series of Advisers Managers Trust
(each a "Portfolio") at the direction or request of N&B Management in connection
with N&B Management's discharge of its obligations under the Agreement shall be
liable for any error of judgment or mistake of law or for any loss suffered by a
Series in connection with any matter to which the Agreement relates; provided,
that nothing in the Agreement shall be construed (i) to protect N&B Management
against any liability to Advisers Managers Trust or a Series of Advisers
Managers Trust or its interest holders to which N&B Management would otherwise
be subject by reason of willful misfeasance, bad faith, or gross negligence in
the performance of N&B Management's duties, or by reason of N&B Management's


<PAGE>


PART C - Other Information
Page 6


reckless disregard of its obligations and duties under the Agreement, or (ii) to
protect any director, officer or employee of N&B Management who is or was a
Trustee or officer of Advisers Managers Trust against any liability to Advisers
Managers Trust or a Series or its interest holders to which such person would
otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
person's office with Advisers Managers Trust.

                  Section 1 of the Sub-Advisory Agreement between Advisers
Managers Trust and Neuberger & Berman, L.P. ("Sub- Adviser") provides that in
the absence of willful misfeasance, bad faith or gross negligence in the
performance of its duties, or of reckless disregard of its duties and
obligations under the Agreement, the Sub-Adviser will not be subject to
liability for any act or omission or any loss suffered by any Series of Advisers
Managers Trust or its interest holders in connection with the matters to which
the Agreement relates.
   
                  Section 9.1 of the Administration Agreement between the
Registrant and N&B Management provides that N&B Management will not be liable to
the Registrant for any action taken or omitted to be taken by N&B Management in
good faith and with due care in accordance with such instructions, or with the
advice or opinion, of legal counsel for a Portfolio of the Trust or for the
Administrator in respect of any matter arising in connection with the
Administration Agreement. N&B Management shall be protected in acting upon any
such instructions, advice or opinion and upon any other paper or document
delivered by a Portfolio or such legal counsel which N&B Management believes to
be genuine and to have been signed by the proper person or persons, and N&B
Management shall not be held to have notice of any change of status or authority
of any officer or representative of the Trust, until receipt of written notice
thereof from the Portfolio. Section 12 of the Administration Agreement provides
that each Portfolio of the Registrant shall indemnify N&B Management and hold it
harmless from and against any and all losses, damages and expenses, including
reasonable attorneys' fees and expenses, incurred by N&B Management that result
from: (i) any claim, action, suit or proceeding in connection with N&B
Management's entry into or performance of the Agreement with respect to such
Portfolio; or (ii) any action taken or omission to act committed by N&B
Management in the performance of its obligations under the Agreement with
respect to such Portfolio; or (iii) any action of N&B Management upon
instructions believed in good faith by it to have been executed by a duly
authorized officer or representative of the Trust with respect to such
Portfolio; provided, that N&B Management will not be entitled to such
indemnification in respect of actions or omissions constituting negligence or


<PAGE>


PART C - Other Information
Page 7


misconduct on the part of N&B Management, or its employees, agents or
contractors. Amounts payable by the Registrant under this provision shall be
payable solely out of assets belonging to that Portfolio, and not from assets
belonging to any other Portfolio of the Registrant. Section 13 of the
Administration Agreement provides that N&B Management will indemnify each
Portfolio of the Registrant and hold it harmless from and against any and all
losses, damages and expenses, including reasonable attorneys' fees and expenses,
incurred by such Portfolio of the Registrant that result from: (i) N&B
Management's failure to comply with the terms of the Agreement; or (ii) N&B
Management's lack of good faith in performing its obligations under the
Agreement; or (iii) the negligence or misconduct of N&B Management, or its
employees, agents or contractors in connection with the Agreement. A Portfolio
of the Registrant shall not be entitled to such indemnification in respect of
actions or omissions constituting negligence or misconduct on the part of that
Portfolio or its employees, agents or contractors other than N&B Management,
unless such negligence or misconduct results from or is accompanied by
negligence or misconduct on the part of N&B Management, any affiliated person of
N&B Management, or any affiliated person of an affiliated person of N&B
Management.
    
                  Section  11  of  the   Distribution   Agreement   between  the
Registrant  and N&B Management  provides that N&B Management  shall look only to
the assets of a Portfolio for the  Registrant's  performance of the Agreement by
the Registrant on behalf of such Portfolio,  and neither the Trustees nor any of
the Registrant's officers, employees or agents, whether past, present or future,
shall be personally liable therefor.

                  Insofar as indemnification for liabilities arising under the
Securities Act of 1933 ("1933 Act") may be permitted to trustees, officers and
controlling persons of the Registrant pursuant to the foregoing provisions, or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission, such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a trustee, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer or controlling person, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the 1933 Act and will be governed by the final adjudication of such
issue.

                               CUSTODIAN CONTRACT


         This Contract between  Neuberger & Berman Advisers  Management Trust, a
Delaware  business  trust,  having its principal  place of business at 605 Third
Avenue,  New York,  New York 10158,  hereinafter  called the  "Fund",  and State
Street  Bank and Trust  Company,  a  Massachusetts  trust  company,  having  its
principal  place of  business at 225  Franklin  Street,  Boston,  Massachusetts,
02110, hereinafter called the "Custodian",


                                   WITNESSETH:

         WHEREAS,  the Fund is  authorized  to issue shares in separate  series,
with  each  such  series  representing  interests  in a  separate  portfolio  of
securities and other assets; and

         WHEREAS,  the  Fund  has  issued  shares  in six  portfolios,  Balanced
Portfolio, Growth Portfolio, Liquid Asset Portfolio, Limited Maturity Portfolio,
Partners  Portfolio,  and Government Income Portfolio (such Portfolios  together
with all other series  subsequently  established by the Fund and made subject to
this Contract in accordance  with paragraph 17, being herein  referred to as the
"Portfolio(s)");

         NOW THEREFORE,  in consideration of the mutual covenants and agreements
hereinafter contained, the parties hereto agree as follows:


1.       Employment of Custodian and Property to be Held by It

         The Fund hereby employs the Custodian as the custodian of the assets of
each Portfolio, including securities which the Fund, on behalf of the applicable
Portfolio, desires to be held in places within the United States ("domestic
securities") and securities it desires to be held outside the United States
("foreign securities") pursuant to the provisions of the Trust Instrument. The
Fund on behalf of each Portfolio agrees to deliver to the Custodian all
securities and cash of the Portfolios, and all payments of income, payments of
principal or capital distributions received by it with respect to all securities
owned by the Portfolio(s) from time to time, and the cash consideration received
by it for such new or treasury shares of beneficial interest of the Fund
representing interests in the Portfolios ("Shares"), as may be issued or sold
from time to time. The Custodian shall not be responsible for any property of a
Portfolio held or received by the Portfolio and not delivered to the Custodian.


<PAGE>


         Upon receipt of "Proper Instructions" (within the meaning of Article
5), the Custodian shall on behalf of the applicable Portfolio(s) from time to
time employ one or more sub-custodians located in the United States, but only in
accordance with an applicable vote by the Board of Trustees of the Fund on
behalf of the applicable Portfolio(s), and provided that the Custodian shall
have no more or less responsibility or liability to the Fund on account of any
actions or omissions of any sub-custodian so employed than any such
sub-custodian has to the Custodian. The Custodian may employ as sub-custodian
for the Fund's foreign securities on behalf of the applicable Portfolio(s) the
foreign banking institutions and foreign securities depositories designated in
Schedule A hereto but only in accordance with the provisions of Article 3.

2.       Duties of the Custodian with Respect to Property of the Fund Held By
         the Custodian in the United States

2.1      Holding Securities. The Custodian shall hold and physically segregate
         for the account of each Portfolio all non-cash property to be held by

         such Portfolio, other than (a) securities which are maintained pursuant
         to Section 2.10 in a clearing agency which acts as a securities
         depository or in a book-entry system authorized by the U.S. Department
         of the Treasury, collectively referred to herein as "Securities System"
         and (b) commercial paper of an issuer for which State Street Bank and
         Trust Company acts as issuing and paying agent ("Direct Paper") which
         is deposited and/or maintained in the Direct Paper System of the
         Custodian pursuant to Section 2.11.

2.2      Delivery of Securities. The Custodian shall release and deliver
         domestic securities owned by a Portfolio held by the Custodian or in a
         Securities System account of the Custodian or in the Custodian's Direct
         Paper book entry system account ("Direct Paper System Account") only
         upon receipt of Proper Instructions from the Fund on behalf of the
         applicable Portfolio, which may be continuing instructions when deemed
         appropriate by the parties, and only in the following cases:

                  other consideration is to be delivered to the Custodian;

                  delivery" custom; provided that in any such case, the
                  Custodian shall have no responsibility or liability for
                  any loss arising from the delivery of such securities
                  prior to receiving payment for such securities except as
                  may arise from the Custodian's own negligence or willful
                  misconduct;

         8)       For exchange or conversion pursuant to any plan of
                  merger, consolidation, recapitalization, reorganization

                  securities, or pursuant to provisions for conversion
                  contained in such securities, or pursuant to any deposit
                  agreement; provided that, in any such case, the new
                  securities and cash, if any, are to be delivered to the

                  Custodian;

         10)      For delivery in connection with any loans of securities made
                  by the Portfolio, but only against receipt of adequate
                  collateral as agreed upon from time to time by the Custodian
                  and the Fund on behalf of the Portfolio, which may be in the

                  to whom delivery of such securities shall be made.

2.3      Registration of Securities. Domestic securities held by the Custodian
         (other than bearer securities) shall be registered in the name of the
         Portfolio or in the name of any nominee of the Fund on behalf of the
         Portfolio or of any nominee of the Custodian which nominee shall be
         assigned exclusively to the Portfolio, unless the Fund has authorized
         in writing the appointment of a nominee to be used in common with other

         the Portfolio, or in the name or nominee name of any agent appointed
         pursuant to Section 2.9 or in the name or nominee name of any
         sub-custodian appointed pursuant to Article 1. All securities accepted
         by the Custodian on behalf of the Portfolio under the terms of this
         Contract shall be in "street name" or other good delivery form. If,
         however, the Fund directs the Custodian to maintain securities in
         "street name", the Custodian shall utilize its best efforts only to
         timely collect income due the Fund on such securities and to notify the
         Fund on a best efforts basis only of relevant corporate actions
         including, without limitation, pendency of calls, maturities, tender or
         exchange offers.

2.4      Bank Accounts. The Custodian shall open and maintain a separate bank
         account or accounts in the United States in the name of each Portfolio
         of the Fund which shall contain only property held by the Custodian as
         custodian for that Portfolio, subject only to draft or order by the
         Custodian acting pursuant to the terms of this Contract, and shall hold
         in such account or accounts, subject to the provisions hereof, all cash
         received by it from or for the account of the Portfolio, other than
         cash maintained by the Portfolio in a bank account established and used
         in accordance with Rule 17f-3 under the Investment Company Act of 1940.
         Funds held by the Custodian for a Portfolio may be deposited by it to
         its credit as Custodian in the Banking Department of the Custodian or
         in such other banks or trust companies as it may in its discretion deem
         necessary or desirable; provided, however, that every such bank or
         trust company shall be qualified to act as a custodian under the
         Investment Company Act of 1940 and that each such bank or trust company
         and the funds to be deposited with each such bank or trust company
         shall on behalf of each applicable Portfolio be approved by vote of a
         majority of the Board of Trustees of the Fund. Such funds shall be
         deposited by the Custodian in its capacity as Custodian and shall be
         withdrawable by the Custodian only in that capacity.

2.5      Availability of Federal Funds. Upon mutual agreement between the Fund
         on behalf of each applicable Portfolio and the Custodian, the Custodian
         shall, upon the receipt of Proper Instructions from the Fund on behalf
         of a Portfolio, make federal funds available to such Portfolio as of
         specified times agreed upon from time to time by the Fund and the
         Custodian in the amount of checks received in payment for Shares of
         such Portfolio which are deposited into the Portfolio's account.
                                                     
<PAGE>





2.6      Collection of Income.  Subject to the provisions of Section

2.3,     the Custodian shall collect on a timely basis all income and other
         payments with respect to registered domestic securities held hereunder
         to which each Portfolio shall be entitled either by law or pursuant to
         custom in the securities business, and shall collect on a timely basis
         all income and other payments with respect to bearer domestic
         securities if, on the date of payment by the issuer, such securities
         are held by the Custodian or its agent and shall credit such income, as
         collected, to such Portfolio's custodian account. Without limiting the
         generality of the foregoing, the Custodian shall detach and present for
         payment all coupons and other income items requiring presentation as
         and when they become due and shall collect interest when due on
         securities held hereunder. Collection of income due each Portfolio on
         securities loaned pursuant to the provisions of Section 2.2 (10) shall
         be the responsibility of the Custodian so long as the securities are
         registered and remain in the name of the Fund, the Custodian, or its
         nominee, or in the Depository Trust Company account of the Custodian,
         but otherwise shall be the responsibility of the Fund and the Custodian
         will have no duty or responsibility in connection therewith, other than
         to provide the Fund with such information or data as may be necessary
         to assist the Fund in arranging for the timely delivery to the
         Custodian of the income to which the Portfolio is properly entitled.

2.7      Payment of Fund Monies. Upon receipt of Proper Instructions from the
         Fund on behalf of the applicable Portfolio, which may be continuing
         instructions when deemed appropriate by the parties, the Custodian
         shall pay out monies of a Portfolio in the following cases only:

         1)       Upon the purchase of domestic securities, options,
                  futures contracts or options on futures contracts for the

                  options, futures contracts or options on futures
                  contracts to the Custodian (or any bank, banking firm or
                  trust company doing business in the United States or
                  abroad which is qualified under the Investment Company
                  Act of 1940, as amended, to act as a custodian and has

                  the case of a purchase effected through a Securities

         any and every case where payment for purchase of domestic securities
         for the account of a Portfolio is made by the Custodian in advance of
         receipt of the securities purchased in the absence of specific written
         instructions from the Fund on behalf of such Portfolio to so pay in
         advance, the Custodian shall be absolutely liable to the Fund for such
         securities to the same extent as if the securities had been received by
         the Custodian.

         as its agent to carry out such of the provisions of this Article 2 as
         the Custodian may from time to time direct; provided, however, that the
         appointment of any agent shall not relieve the Custodian of its
         responsibilities or liabilities hereunder.

2.10     Deposit of Fund Assets in Securities Systems. The Custodian may deposit
         and/or maintain securities owned by a Portfolio in a clearing agency

         1)       The Custodian may keep securities of the Portfolio in a

                  represented in an account ("Account") of the Custodian in the
                  Securities System which shall not include any assets of the

                  System that payment for such securities has been transferred
                  to the Account, and (ii) the making of an entry on the records
                  of the Custodian to reflect such transfer and payment for the
                  account of the Portfolio. Copies of all advices from the
                  Securities System of transfers of securities for the account
                  of the Portfolio shall identify the Portfolio, be maintained
                  for the Portfolio by the Custodian and be provided to the Fund
                  at its request. Upon request, the Custodian shall furnish the

                  reflecting each day's transactions in the Securities System
                  for the account of the Portfolio;

         4)       The Custodian shall provide the Fund for the Portfolio with
                  any report obtained by the Custodian (or by any agent

                  Securities System's accounting system, internal accounting

                  Custodian shall be liable to the Fund for the benefit of the
                  Portfolio for any loss or damage to the Portfolio resulting
                  from use of the Securities System by reason of any negligence,
                  misfeasance or misconduct of the Custodian or any of its
                  agents or of any of its or their employees or from failure of
                  the Custodian or any such agent to enforce effectively such
                  rights as it may have against the Securities System; at the
                  election of the Fund, it shall be entitled to be subrogated to
                  the rights of the Custodian with respect to any claim against
                  the Securities System or any other person which the Custodian
                  may have as a consequence of any such loss or damage if and to
                  the extent that the Portfolio has not been made whole for any
                  such loss or damage.

         Custodian may deposit and/or maintain securities owned by a

3.       Duties of the Custodian with Respect to Property of the Fund
         Held Outside of the United States

3.1      Appointment of Foreign Sub-Custodians. The Fund hereby authorizes and
         instructs the Custodian to employ as sub-custodians for each
         Portfolio's securities and other assets maintained outside the United
         States the foreign banking institutions and foreign securities
         depositories designated on Schedule A hereto ("foreign
         sub-custodians"). Upon receipt of "Proper Instructions", as defined in
         Section 5 of this Contract, together with a certified resolution of the
         Fund's Board of Trustees, the Custodian and the Fund may agree to amend
         Schedule A hereto from time to time to designate additional foreign
         banking institutions and foreign securities depositories to act as
         sub-custodian. Upon receipt of Proper Instructions, the Fund may
         instruct the Custodian to cease the employment of any one or more such
         sub-custodians for maintaining custody of a Portfolio's assets.


3.3      Foreign Securities Depositories. Except as may otherwise be agreed upon
         in writing by the Custodian and the Fund, assets of each Portfolio
         shall be maintained in foreign securities depositories only through
         arrangements implemented by the foreign banking institutions serving as
         sub-custodians pursuant to the terms hereof. Where possible, such
         arrangements shall include entry into agreements containing the
         provisions set forth in Section 3.4 hereof.

3.4      Agreements with Foreign Banking Institutions. Each agreement
         with a foreign banking institution shall be substantially in

                                                     

<PAGE>




3.5      Access of Independent Accountants of the Fund. Upon request of the
         Fund, the Custodian will use its best efforts to arrange for the
         independent accountants of the Fund to be afforded access to the books
         and records of any foreign banking institution employed as a foreign
         sub-custodian insofar as such books and records relate to the
         performance of such foreign banking institution under its agreement
         with the Custodian.

3.6      Reports By Custodian. The Custodian will supply to the Fund from time
         to time, as mutually agreed upon, statements in respect of the
         securities and other assets of each Portfolio held by foreign
         sub-custodians, including but not limited to an identification of
         entities having possession of each Portfolio's securities and other
         assets and advice or notifications of any transfers of securities to or
         from each custodial account maintained by a foreign banking institution
         for the Custodian on behalf of each applicable Portfolio indicating, as
         to securities acquired for a Portfolio, the identity of the entity
         having physical possession of such securities.

3.7      Transactions in Foreign Custody Account. (a) Except as otherwise
         provided in paragraph (b) of this Section 3.7, the provision of
         Sections 2.2 and 2.7 of this Contract shall apply, mutatis mutandis to
         the foreign securities of the Fund held outside the United States by
         foreign sub-custodians.

         (b) Notwithstanding any provision of this Contract to the contrary,
         settlement and payment for securities received for the account of each
         applicable Portfolio and delivery of securities maintained for the
         account of each applicable Portfolio may be effected in accordance with
         the customary securities trading or securities processing practices and
                                                     

<PAGE>


         established procedures in the jurisdiction or market in which the
         transaction occurs, including, without limitation, delivering
         securities to the purchaser thereof or to a dealer therefor (or an
         agent for such purchaser or dealer) against a receipt with the
         expectation of receiving later payment for such securities from such
         purchaser or dealer.

         (c) Securities maintained in the custody of a foreign sub-custodian may
         be maintained in the name of such entity's nominee to the same extent
         as set forth in Section 2.3 of this Contract, and the Fund agrees to
         hold any such nominee harmless from any liability as a holder of record
         of such securities.

3.8      Liability of Foreign Sub-Custodians. Each agreement pursuant to which
         the Custodian employs a foreign banking institution as a foreign
         sub-custodian shall require the institution to exercise reasonable care
         in the performance of its duties and to indemnify, and hold harmless,
         the Custodian and the Fund from and against any loss, damage, cost,
         expense, liability or claim arising out of or in connection with the
         institution's performance of such obligations. At the election of the
         Fund, it shall be entitled to be subrogated to the rights of the
         Custodian with respect to any claims against a foreign banking
         institution as a consequence of any such loss, damage, cost, expense,
         liability or claim if and to the extent that the Fund has not been made
         whole for any such loss, damage, cost, expense, liability or claim.


                                                     
<PAGE>



         like, in each case under circumstances where the Custodian and
         State Street London Ltd. have exercised reasonable care.

3.10     Reimbursement for Advances. If the Fund requires the Custodian to
         advance cash or securities for any purpose for the benefit of a
         Portfolio including the purchase or sale of foreign exchange or of
         contracts for foreign exchange ("Advance"), or in the event that the
         Custodian or its nominee shall incur or be assessed any taxes, charges,
         expenses, assessments, claims or liabilities in connection with the
         performance of this Contract, except such as may arise from its or its
         nominee's own negligent action, negligent failure to act or willful
         misconduct ("Liability") then in such event property equal in value to
         not more than 125% of such Advance and accrued interest on the Advance
         or the anticipated amount of such Liability, held at any time for the
         account of the appropriate Portfolio by the Custodian or sub-custodian
         may be held as security for such Liability or for such Advance and
         accrued interest on the Advance. The Custodian shall designate the
         security or securities constituting security for an Advance or
         Liability (the "Designated Securities") by notice in writing to the
         Fund (which may be sent by tested telefax or telex). In the event the
         value of the Designated Securities shall decline to less than 110% of
         the amount of such Advance and accrued interest on the Advance or the
         anticipated amount of such Liability, then the Custodian may designate
         in the same manner an additional security for such obligation
         ("Additional Securities"), but the aggregate value of the Designated
         Securities and Additional Securities shall not be in excess of 125% of
         the amount of such Advance and the accrued interest on the Advance or
         the anticipated amount of such Liability. At the request of the Fund,
         on behalf of a Portfolio, the Custodian shall agree to substitution of
         a security or securities which have a value equal to the value of the
         Designated or Additional Securities which the Fund desires be released
         from their status as security, and such release from status as security
         shall be effective upon the Custodian and the Fund agreeing in writing
         as to the identity of the substituted security or securities, which
         shall thereupon become Designated Securities.

         Notwithstanding the above, the Custodian shall, at the request of the
         Fund, on behalf of a Portfolio, immediately release from their status
         as security any or all of the Designated Securities or Additional
         Securities upon the Custodian's receipt from such Portfolio of cash or
         cash equivalents in an amount equal to 100% of the value of the
         Designated Securities or Additional Securities that the Fund desires to
         be released from their status as security pursuant to this Section. The
         applicable Portfolio shall reimburse or indemnify the Custodian in
         respect of a Liability and shall pay any Advances upon demand;
       provided, however, that the Custodian first notified the Fund on behalf 

                                                     

<PAGE>



         of the Portfolio of such demand for repayment, reimbursement or
         indemnification. If, upon notification, the Portfolio shall fail to pay
         such Advance or interest when due or shall fail to reimburse or
         indemnify the Custodian promptly in respect of a Liability, the
         Custodian shall be entitled to dispose of the Designated Securities and
         Additional Securities to the extent necessary to obtain repayment,
         reimbursement or indemnification. Interest, dividends and other
         distributions paid or received on the Designated Securities and
         Additional Securities, other than payments of principal or payments
         upon retirement, redemption or repurchase, shall remain the property of
         the Portfolio, and shall not be subject to this Section. To the extent
         that the disposition of the Portfolio's property, designated as
         security for such Advance or Liability, results in an amount less than
         necessary to obtain repayment, reimbursement or indemnification, the
         Portfolio shall continue to be liable to the Custodian for the
         differences between the proceeds of the disposition of the Portfolio's
         property, designated as security for such Advance or Liability, and the
         amount of the repayment, reimbursement or indemnification due to the
         Custodian and the Custodian shall have the right to designate in the
         same manner described above an additional security for such obligation
         which shall constitute Additional Securities hereunder.

3.11     Monitoring Responsibilities. The Custodian shall furnish annually to
         the Fund, during the month of June, information concerning the foreign
         sub-custodians employed by the Custodian. Such information shall be
         similar in kind and scope to that furnished to the Fund in connection
         with the initial approval of this Contract. In addition, the Custodian
         will promptly inform the Fund in the event that the Custodian learns of
         a material adverse change in the financial condition of a foreign
         sub-custodian or any material loss of the assets of the Fund or, in the
         case of any foreign sub-custodian not the subject of an appropriate
         exemptive order from the Securities and Exchange Commission, is
         notified by such foreign sub-custodian that there appears to be a
         substantial likelihood that its shareholders' equity will decline below
         $200 million (U.S. dollars or the equivalent thereof) or that its
         shareholders' equity has declined below $200 million (in each case
         computed in accordance with generally accepted U.S. accounting
         principles).

3.12     Branches of U.S. Banks. (a) Except as otherwise set forth in this
         Contract, the provisions hereof shall not apply where the custody of a
         Portfolio's assets are maintained in a foreign branch of a banking
         institution which is a "bank" as defined by Section 2(a)(5) of the
         Investment Company Act of 1940 meeting the qualification set forth in
         Section 26(a) of said securities trading or securities processing
         practices and securities trading or securities processing practices and
                                                    

<PAGE>



         Act.  The appointment of any such branch as a sub-custodian
         shall be governed by paragraph 1 of this Contract.

         (b) Cash held for each Portfolio of the Fund in the United Kingdom
         shall be maintained in an interest bearing account established for the
         Fund with the Custodian's London branch, which account shall be subject
         to the direction of the Custodian, State Street London Ltd. or both.

3.13     Foreign Exchange Transactions. (a) Upon receipt of Proper Instructions,
         the Custodian shall settle foreign exchange contracts or options to
         purchase and sell foreign currencies for spot and future delivery on
         behalf of and for the account of a Portfolio with such brokers, banks
         or trust companies other than the Custodian ("Currency Brokers") as the
         Fund may determine and direct pursuant to Proper Instructions or as the
         Custodian may select ("Transactions Other Than As Principal").

         (b) The Custodian shall not be obligated to enter into foreign exchange
         transactions as principal ("Transactions As Principal"). However, if
         the Custodian has made available to the Fund its services as a
         principal in foreign exchange transactions and subject to any separate
         agreement between the parties relating to such transactions, the
         Custodian shall enter into foreign exchange contracts or options to
         purchase and sell foreign currencies for spot and future delivery on
         behalf of and for the account of a Portfolio, with the Custodian as
         principal.

         (c) If, in a Transaction Other Than As Principal, a Currency Broker is
         selected by the Fund, on behalf of a Portfolio, the Custodian shall
         have no duty with respect to the selection of the Currency Broker, or,
         so long as the Custodian acts in accordance with Proper Instructions,
         for the failure of such Currency Broker to comply with the terms of any
         contract or option. If, in a Transaction Other Than As Principal, the
         Currency Broker is selected by the Custodian or if the Custodian enters
         into a Transaction As Principal, the Custodian shall be responsible for
         the selection of the Currency Broker and the failure of such Currency
         Broker to comply with the terms of any contract or option.

         (d) In Transactions Other Than As Principal and Transactions As
         Principal, the Custodian shall be responsible for any transfer of cash,
         the transmission of instructions to and from a Currency Broker, if any,
         the safekeeping of all certificates and other documents and agreements
         evidencing or relating to such foreign exchange transactions and the
         maintenance of proper records as set forth in Section 9 of this
         Contract.

3.14     Tax Law.  Except to the extent that imposition of any tax
         liability arises from State Street's failure to perform in

                                                    


<PAGE>



         accordance with the terms of this Section 3.14 or from the failure of
         any sub-custodian to perform in accordance with the terms of the
         applicable subcustody agreement, State Street shall have no
         responsibility or liability for any obligations now or hereafter
         imposed on each Portfolio by the tax law of the domicile of each
         Portfolio or of any jurisdiction in which each Portfolio is invested or
         any political subdivision thereof. It shall be the responsibility of
         State Street to use due care to perform such steps as are required to
         collect any tax refund, to ascertain the appropriate rate of tax
         withholding and to provide such information and documents as may be
         required to enable each Portfolio to receive appropriate tax treatment
         under applicable tax laws and any applicable treaty provisions. Unless
         otherwise informed by each Portfolio, State Street, in performance of
         its duties under this Section, shall be entitled to apply categorical
         treatment of each Portfolio according to the nationality of each
         Portfolio, the particulars of its organization and other relevant
         details that shall be supplied by each Portfolio. State Street shall be
         entitled to rely on any information supplied by each Portfolio. State
         Street may engage reasonable professional advisors disclosed to each
         Portfolio by State Street, which may include attorneys, accountants or
         financial institutions in the regular business of investment
         administration and may rely upon advice received therefrom. It shall be
         the duty of each Portfolio to inform State Street of any change in the
         organization, domicile or other relevant fact concerning tax treatment
         of each Portfolio and further to inform State Street if each Portfolio
         is or becomes the beneficiary of any special ruling or treatment not
         applicable to the general nationality and category of entity of which
         each Portfolio is a part under general laws and treaty provisions.

4.       Payments for Sales or Repurchases or Redemptions of the Fund
         Shares of the Fund

         The Custodian shall receive from the distributor for the Shares or from
the Transfer Agent of the Fund and deposit into the account of the appropriate
Portfolio such payments as are received for Shares of that Portfolio issued or
sold from time to time by the Fund. The Custodian will provide timely
notification to the Fund on behalf of each such Portfolio and to the Transfer
Agent of any receipt by the Custodian of payments for Shares of such Portfolio.

         From such funds as may be available for the purpose but subject to the
limitations of the Trust Instrument and any applicable votes of the Board of
Trustees of the Fund pursuant thereto, the Custodian shall, upon receipt of
instructions from the Transfer Agent, make funds available for payment to
holders of Shares who have delivered to the Transfer Agent a request for

                                                     

<PAGE>



redemption or repurchase of their Shares. The Custodian will provide timely
notification to the Fund on behalf of each such Portfolio and to the Transfer
Agent of any disbursement by the Custodian of payments for Shares of such
Portfolio. In connection with the redemption or repurchase of Shares of a
Portfolio, the Custodian is authorized upon receipt of instructions from the
Transfer Agent to wire funds to or through a commercial bank designated by the
redeeming shareholders. In connection with the redemption or repurchase of
Shares of the Fund, the Custodian shall honor checks drawn on the Custodian by a
holder of Shares, which checks have been furnished by the Fund to the holder of
Shares, when presented to the Custodian in accordance with such procedures and
controls as are mutually agreed upon from time to time between the Fund and the
Custodian.

5.       Proper Instructions

         Proper Instructions as used throughout this Contract means a writing
signed or initialled by two or more persons as the Board of Trustees shall have
from time to time authorized. Each such writing shall set forth the specific
transaction or type of transaction involved, including a specific statement of
the purpose for which such action is requested. Oral instructions will be
considered Proper Instructions if the Custodian reasonably believes them to have
been given by a person authorized to give such instructions with respect to the
transaction involved. The Fund shall cause all oral instructions to be confirmed
in writing. Upon receipt of a certificate of the Secretary or an Assistant
Secretary as to the authorization by the Board of Trustees of the Fund
accompanied by a detailed description of procedures approved by the Board of
Trustees, Proper Instructions may include communications effected directly
between electro-mechanical or electronic devices provided that the Fund and the
Custodian are satisfied that such procedures afford adequate safeguards for the
Portfolios' assets. For purposes of this Section, Proper Instructions shall
include instructions received by the Custodian pursuant to any three party
agreement which requires a segregated asset account in accordance with Section
2.12.

6.       Actions Permitted without Express Authority

         The Custodian may in its discretion, without express authority from the
Fund on behalf of each applicable Portfolio:

         1)       make payments to itself or others for minor expenses of
                  handling securities or other similar items relating to
                  its duties under this Contract, provided that all such
                  payments shall be accounted for to the Fund on behalf of
                  the Portfolio;

         2)       surrender securities in temporary form for securities in
                  definitive form;

                                                   

<PAGE>




         3)       endorse for collection, in the name of the Portfolio,
                  checks drafts and other negotiable instruments; and

         4)       in general, attend to all non-discretionary details in
                  connection with the sale, exchange, substitution, purchase,
                  transfer and other dealings with the securities and property
                  of the Portfolio except as otherwise directed by the Board of
                  Trustees of the Fund.

7.       Evidence of Authority

         The Custodian shall be protected in acting upon any instructions,
notice, request, consent, certificate or other instrument or paper believed by
it to be genuine and to have been properly executed by or on behalf of the Fund.
The Custodian may receive and accept a certified copy of a vote of the Board of
Trustees of the Fund as conclusive evidence (a) of the authority of any person
to act in accordance with such vote or (b) of any determination or of any action
by the Board of Trustees pursuant to the Trust Instrument as described in such
vote, and such vote may be considered as in full force and effect until receipt
by the Custodian of written notice to the contrary.

8.       Duties of Custodian with Respect to the Books of Account and
         Calculation of Net Asset Value and Net Income

         If, and to the extent requested by the Fund, the Custodian shall
cooperate with and supply necessary information to the entity or entities
appointed by the Board of Trustees of the Fund to keep the books of account of
each Portfolio and/or compute the net asset value per share of the outstanding
shares of each Portfolio or, if directed in writing to do so by the Fund on
behalf of the Portfolio, shall itself keep such books of account and/or compute
such net asset value per share. If so directed, the Custodian shall also
calculate daily the net income of the Portfolio as described in the Fund's
currently effective prospectus related to such Portfolio and shall advise the
Fund and the Transfer Agent daily of the total amounts of such net income and,
if instructed in writing by an officer of the Fund to do so, shall advise the
Transfer Agent periodically of the division of such net income among its various
components. The calculations of the net asset value per share and the daily
income of each Portfolio shall be made at the time or times described from time
to time in the Fund's currently effective prospectus related to such Portfolio.

9.       Records

         The Custodian shall with respect to each Portfolio create and maintain
all records relating to its activities and obligations under this Contract in
such manner as will meet the obligations of the Fund under the Investment
Company Act of 1940, with particular attention to Section 31 thereof and Rules

                                                     

<PAGE>


31a-1 and 31a-2 thereunder. All such records shall be the property of the Fund
and shall at all times during the regular business hours of the Custodian be
open for inspection by duly authorized officers, employees or agents of the Fund
and employees and agents of the Securities and Exchange Commission. The
Custodian shall, at the Fund's request, supply the Fund with a tabulation of
securities owned by each Portfolio and held by the Custodian and shall, when
requested to do so by the Fund and for such compensation as shall be agreed upon
between the Fund and the Custodian, include certificate numbers in such
tabulations.

10.      Opinion of Fund's Independent Accountant

         The Custodian shall take all reasonable action, as the Fund on behalf
of each applicable Portfolio may from time to time request, to obtain from year
to year favorable opinions from the Fund's independent accountants with respect
to its activities hereunder in connection with the preparation of the Fund's
Form N-lA, and Form N-SAR or other annual reports to the Securities and Exchange
Commission and with respect to any other requirements of such commission.

11.      Reports to Fund by Independent Public Accountants

         The Custodian shall provide the Fund, on behalf of each Portfolio at
such times as the Fund may reasonably require, with reports by independent
public accountants on the accounting system, internal accounting control and
procedures for safeguarding securities, futures contracts and options on futures
contracts, including securities deposited and/or maintained in a Securities
System, relating to the services provided by the Custodian under this Contract;
such reports shall be of sufficient scope and in sufficient detail as may
reasonably be required by the Fund to provide reasonable assurance that any
material inadequacies would be disclosed by such examination, and, if there are
no such inadequacies, the reports shall so state.

12.      Compensation of Custodian

         The Custodian shall be entitled to reasonable compensation for its
services and expenses as Custodian, as agreed upon from time to time between the
Fund on behalf of each applicable Portfolio and the Custodian.

13.      Responsibility of Custodian

         So long as and to the extent that it is in the exercise of reasonable
care, the Custodian shall not be responsible for the title, validity or
genuineness of any property or evidence of title thereto received by it or
delivered by it pursuant to this Contract and shall be held harmless in acting
upon any notice, request, consent, certificate or other instrument reasonably
believed by it and to be signed by the proper party or parties, including any

                                                    

<PAGE>



to be genuine futures commission merchant acting pursuant to the terms of a
three-party futures or options agreement. The Custodian shall be held to the
exercise of reasonable care in carrying out the provisions of this Contract, but
shall be kept indemnified by and shall be without liability to the Fund for any
action taken or omitted by it in good faith without negligence. It shall be
entitled to rely on and may act upon advice of counsel (who may be counsel for
the Fund) on all matters, and shall be without liability for any action
reasonably taken or omitted pursuant to such advice.

         As a condition to the indemnification provided for in this Section 13,
if in any case the indemnifying party is asked to indemnify and hold the
indemnified party harmless, the indemnified party shall fully and promptly
advise the indemnifying party of all pertinent facts concerning the situation in
question, and shall use all reasonable care to identify, and promptly notify the
indemnifying party of, any situation which presents or appears likely to present
the probability of such a claim for indemnification against the indemnifying
party. The indemnifying party shall be entitled, at its own expense, to
participate in the investigation and to be consulted as to the defense of any
such claim, and in such event, the indemnified party shall keep the indemnifying
party fully and currently informed of all developments relating to such
investigation or defense. At any time, the indemnifying party shall be entitled
at its own expense to conduct the defense of any such claim, provided that the
indemnifying party: (a) reasonably demonstrates to the other party its ability
to pay the full amount of potential liability in connection with such claim and
(b) first admits in writing to the other party that such claim is one in respect
of which the indemnifying party is obligated to indemnify the other party
hereunder. Upon satisfaction of the foregoing conditions, the indemnifying party
shall take over complete defense of the claim, and the indemnified party shall
initiate no further legal or other expenses for which it shall seek
indemnification. The indemnified party shall in no case confess any claim or
make any compromise in any case in which the indemnifying party may be asked to
indemnify the indemnified party, except with the indemnifying party's prior
written consent.

         If the Fund on behalf of a Portfolio requires the Custodian to take any
action with respect to securities, which action involves the payment of money or
which action may, in the opinion of the Custodian, result in the Custodian or
its nominee assigned to the Fund or the Portfolio being liable for the payment
of money or incurring liability of some other form, the Fund on behalf of the
Portfolio, as a prerequisite to requiring the Custodian to take such action,
shall provide indemnity to the Custodian in an amount and form satisfactory to
it.

14.      Effective Period, Termination and Amendment

         This Contract shall become effective as of its execution, shall
continue in full force and effect with respect to each Portfolio until
terminated as hereinafter provided, may be amended at any time by mutual
agreement of the parties hereto and may be terminated by either party by an
instrument in writing delivered or mailed, postage prepaid to the other party,
such termination to take effect not sooner than thirty (30) days after the date
of such delivery or mailing; provided, however that the Custodian shall not with
respect to a Portfolio act under Section 2.10 hereof in the absence of receipt
of an initial certificate of the Secretary or an Assistant Secretary that the
Board of Trustees of the Fund has approved the use of a particular Securities
System by such Portfolio as required by Rule 17f-4 under the Investment Company
Act of 1940, as amended and that the Custodian shall not with respect to a
Portfolio act under Section 2.11 hereof in the absence of receipt of an initial
certificate of the Secretary or an Assistant Secretary that the Board of
Trustees has approved the initial use- of the Direct Paper System by such
Portfolio and the receipt of an annual certificate of the Secretary or an
Assistant Secretary that the Board of Trustees has reviewed the use by such
Portfolio of the Direct Paper System; provided further, however, that the Fund
shall not amend or terminate this Contract in contravention of any applicable
federal or state regulations, or any provision of the Trust Instrument, and
further provided, that the Fund on behalf of one or more of the Portfolios may
at any time by action of its Board of Trustees (i) substitute another bank or
trust company for the Custodian by giving notice as described above to the
Custodian, or (ii) immediately terminate this Contract in the event of the
appointment of a conservator or receiver for the Custodian by the Comptroller of
the Currency or upon the happening of a like event at the direction of an
appropriate regulatory agency or court of competent jurisdiction.

         Upon termination of the Contract, the Fund on behalf of each applicable
Portfolio shall pay to the Custodian such compensation as may be due as of the
date of such termination and shall likewise reimburse the Custodian for its
costs, expenses and disbursements. Termination of the Contract with respect to
one Portfolio (but less than all of the Portfolios) will not constitute
termination of the Contract, and the terms of the Contract continue to apply to
the other Portfolios.

15.      Successor Custodian

         If a successor custodian for the Fund, of one or more of the Portfolios
shall be appointed by the Board of Trustees of the Fund, the Custodian shall,
upon termination, deliver to such successor custodian at the office of the
Custodian, duly endorsed and in the form for transfer, all securities of each
applicable Portfolio then held by it hereunder and shall transfer to an account
of the successor custodian all of the securities of each such Portfolio
held in a Securities System.

                                                     

<PAGE>


         If no such successor custodian shall be appointed, the Custodian shall,
in like manner, upon receipt of a certified copy of a vote of the Board of
Trustees of the Fund, deliver at the office of the Custodian and transfer such
securities, funds and other properties in accordance with such vote.

         In the event that no written order designating a successor custodian or
certified copy of a vote of the Board of Trustees shall have been delivered to
the Custodian on or before the date when such termination shall become
effective, then the Custodian shall have the right to deliver to a bank or trust
company, which is a "bank" as defined in the Investment Company Act of 1940,
doing business in Boston, Massachusetts, of its own selection, having an
aggregate capital, surplus, and undivided profits, as shown by its last
published report, of not less than $25,000,000, all securities, funds and other
properties held by the Custodian on behalf of each applicable Portfolio and all
instruments held by the Custodian relative thereto and all other property held
by it under this Contract on behalf of each applicable Portfolio and to transfer
to an account of such successor custodian all of the securities of each such
Portfolio held in any Securities System. Thereafter, such bank or trust company
shall be the successor of the Custodian under this Contract.

         In the event that securities, funds and other properties remain in the
possession of the Custodian after the date of termination hereof owing to
failure of the Fund to procure the certified copy of the vote referred to or of
the Board of Trustees to appoint a successor custodian, the Custodian shall be
entitled to fair compensation for its services during such period as the
Custodian retains possession of such securities, funds and other properties and
the provisions of this Contract relating to the duties and obligations of the
Custodian shall remain in full force and effect.

16.      Interpretive and Additional Provisions

         In connection with the operation of this Contract, the Custodian and
the Fund on behalf of each of the Portfolios, may from time to time agree on
such provisions interpretive of or in addition to the provisions of this
Contract as may in their joint opinion be consistent with the general tenor of
this Contract. Any such interpretive or additional provisions shall be in a
writing signed by both parties and shall be annexed hereto, provided that no
such interpretive or additional provisions shall contravene any applicable
federal or state regulations or any provision of the Trust Instrument of the
Fund. No interpretive or additional provisions made as provided in the preceding
sentence shall be deemed to be an amendment of this Contract.

17.      Additional Funds

         In the event that the Fund establishes one or more series of Shares in
addition to Balanced Portfolio, Growth Portfolio, Liquid Asset Portfolio,
Limited Maturity Portfolio, Partners Portfolio, and Government Income Portfolio
with respect to which it desires to have the Custodian render services as
custodian under the terms hereof, it shall so notify the Custodian in writing,
and if the Custodian agrees in writing to provide such services, such series of
Shares shall become a Portfolio hereunder.

18.      Massachusetts Law to Apply

         This Contract shall be construed and the provisions thereof interpreted
under and in accordance with laws of The Commonwealth of Massachusetts.

19.      Limitation of Trustee, Officer and Shareholder Liability

         It is expressly agreed that the obligations of the Fund and each
Portfolio hereunder shall not be binding upon any of the Trustees, officers,
agents or employees of the Fund or upon the shareholders of any Portfolio
personally, but shall only bind the assets and property of the Fund, as provided
in its Trust Instrument. The execution and delivery of this Contract have been
authorized by the Trustees of the Fund, and this Contract has been executed and
delivered by an authorized officer of the Fund acting as such; neither such
authorization by such Trustees nor such execution and delivery by such officer
shall be deemed to have been made by any of them individually or to impose any
liability on any of them personally, but shall bind only the assets and property
of the Fund, as Provided in its Trust Instrument.

20.      No Liability of Other Portfolios

         Notwithstanding any other provision of this Contract, the parties agree
that the assets and liabilities of each Portfolio are separate and distinct from
the assets and liabilities of each other Portfolio and that no Portfolio shall
be liable or shall be charged for any debt, obligation or liability of any other
Portfolio, whether arising under this Contract or otherwise.

21.      Confidentiality

         The Custodian agrees that all books, records, information and data
pertaining to the business of the Fund which are exchanged or received pursuant
to the negotiation or carrying out of this Contract shall remain confidential,
shall not be voluntarily disclosed to any other person, except as may be
required by law, and shall not be used by the Custodian for any purpose not
directly related to the business of the Fund, except with the Fund's written
consent.

22.      Assignment

         Neither the Fund nor the Custodian shall have the right to assign any
of its rights or obligations under this Contract without the prior written
consent of the other party.

23.      Severability

         If any provision of this Contract is held to be unenforceable as a
matter of law, the other terms and provisions hereof shall not be affected
thereby and shall remain in full force and effect.

24.      Prior Contracts

         This Contract supersedes and terminates, as of the date hereof, all
prior contracts between the Fund on behalf of each of the Portfolios, or any
predecessor(s) thereto, and the Custodian relating to the custody of the Fund's
assets.

25.      Shareholder Communications Election

         Securities and Exchange Commission Rule 14b-2 requires banks which hold
securities for the account of customers to respond to requests by issuers of
securities for the names, addresses and holdings of beneficial owners of
securities of that issuer held by the bank unless the beneficial owner has
expressly objected to disclosure of this information. In order to comply with
the rule, the Custodian needs the Fund to indicate whether it authorizes the
Custodian to provide the Fund's name, address, and share position to requesting
companies whose securities the Fund owns. If the Fund tells the Custodian "no",
the Custodian will not provide this information to requesting companies. If the
Fund tells the Custodian "yes" or does not check either "yes" or "no" below, the
Custodian is required by the rule to treat the Fund as consenting to disclosure
of this information for all securities owned by the Fund or any funds or
accounts established by the Fund. For the Fund's protection, the Rule prohibits
the requesting company from using the Fund's name and address for any purpose
other than corporate communications. Please indicate below whether the Fund
consents or objects by checking one of the alternatives below.


         YES      [ ] The  Custodian is  authorized  to release the Fund's name,
                  address, and share positions.

         NO       [ ] The  Custodian  is not  authorized  to release  the Fund's
                  name, address, and share positions.

                  accounts,   preparing  and  mailing  activity  statements  for

                  its agent may perform these services on the Fund's behalf.

         (e)      The Bank shall  provide  additional  services on behalf of the

         time subject to mutual written agreement between the Fund and the Bank.

5.       Data Access and Proprietary Information

5.1      The Fund  acknowledges  that the  computer  programs,  screen  formats,
         report formats (except such screen formats and report formats as may be
         necessary to respond to shareholder problems or inquiries), interactive
         design techniques,  and documentation  manuals furnished to the Fund by
         the Bank as part of the Fund's ability to access  certain  Fund-related
         data ("Customer  Data")  maintained by the Bank on data bases under the
         control and  ownership of the Bank or other third party  ("Data  Access
         Services") constitute  copyrighted,  trade secret, or other proprietary
         information  (collectively,  "Proprietary  Information") of substantial
         value to the Bank or other third party.  In no event shall  Proprietary
        
                                                         

<PAGE>



         Information  be  deemed  Customer  Data.  The Fund  agrees to treat all
         Proprietary  Information  as proprietary to the Bank and further agrees
         that it shall not divulge any Proprietary  Information to any person or
         organization except as may be provided hereunder.  Without limiting the
         foregoing, the Fund agrees for itself and its employees and agents:

         (a)      to  access  Customer  Data  solely  from  locations  as may be
                  designated  in writing  by the Bank and  solely in  accordance
                  with the Bank's applicable user documentation;

         (b)      to  refrain  from  copying  or  duplicating  in  any  way  the
                  Proprietary Information;

         (c)      to refrain from obtaining  unauthorized  access to any portion
                  of  the  Proprietary  Information,   and  if  such  access  is
                  inadvertently  obtained,  to inform in a timely manner of such
                  fact and dispose of such  information  in accordance  with the
                  Bank's instructions;

         (d)      to honor all reasonable  written  requests made by the Bank to
                  protect  at the  Bank's  expense  the  rights  of the  Bank in
                  Proprietary Information at common law, under federal copyright
                  law and under other federal or state law.

Each party  shall take  reasonable  efforts  to advise  its  employees  of their
obligations  pursuant to this Section 5. The  obligations  of this Section shall
survive any earlier termination of this Agreement.

5.2      If the Fund  notifies the Bank that any of the Data Access  Services do
         not operate in material  compliance  with the most recently issued user
         documentation  for such  services,  the Bank shall endeavor in a timely
         manner to correct such failure.  Organizations  from which the Bank may
         obtain  certain  data  included in the Data Access  Services are solely
         responsible  for the  contents of such data and the Fund agrees to make
         no  claim  against  the  Bank  arising  out of  the  contents  of  such
         third-party data, including,  but not limited to, the accuracy thereof.
         DATA  ACCESS   SERVICES   AND  ALL   COMPUTER   PROGRAMS  AND  SOFTWARE
         SPECIFICATIONS  USED IN CONNECTION  THEREWITH ARE PROVIDED ON AN AS IS,
         AS AVAILABLE BASIS. THE BANK EXPRESSLY  DISCLAIMS ALL WARRANTIES EXCEPT
         THOSE  EXPRESSLY  STATED  HEREIN  INCLUDING,  BUT NOT  LIMITED  TO, THE
         IMPLIED  WARRANTIES  OF  MERCHANTABILITY  AND FITNESS FOR A  PARTICULAR
         PURPOSE.

5.3      If the  transactions  available  to the Fund  include  the  ability  to
         originate  electronic  instructions  to the Bank in order to (i) effect
         the transfer or movement of cash or Shares or (ii) transmit Shareholder
         information  or other  information  (such  transactions  constituting a
         "COEFI"),  then in such event the Bank shall be entitled to rely on the
         validity and authenticity of such instruction  without  undertaking any
         further inquiry as long as such instruction is undertaken in conformity
         with security procedures established by the Bank from time to time.

         (c)      The  reliance  on  or  use  by  the  Bank  or  its  agents  or
                  subcontractors of information,  records, documents or services
                  which  (i)  are   received  by  the  Bank  or  its  agents  or
                  subcontractors,  and (ii) have been  prepared,  maintained  or
                  performed by the Fund or any other person or firm on behalf of
                  the Fund  including  but not limited to any previous  transfer
                  agent or registrar.

         (d)      The reasonable reliance on, or the carrying out by the Bank or
                  its agents or  subcontractors  of any instructions or requests

         (e)      The offer or sale of Shares in  violation  of any  requirement
                  under  the  federal  securities  laws  or  regulations  or the
                  securities  laws or  regulations of any state that such Shares
                  be  registered in such state or in violation of any stop order
                  or other  determination or ruling by any federal agency or any
                  state with respect to the offer or sale of such Shares in such
                  state.

6.2      The Bank shall  indemnify and hold the Fund and each Portfolio  thereof
         harmless from and against any and all losses,  damages, costs, charges,
         counsel  fees,  payments,  expenses  and  liability  arising  out of or
         attributed to any action or failure or omission to act by the Bank, its
         employees or agents, as a result of the lack of good faith,  negligence
         or willful misconduct of the Bank, its employees or agents.

6.3      At any  time  the  Bank  may  apply  to any  officer  of the  Fund  for
         instructions,  and may consult  with legal  counsel with respect to any
         matter  arising in connection  with the services to be performed by the
         Bank   under   this   Agreement,   and  the  Bank  and  its  agents  or
         subcontractors shall not be liable and shall be indemnified by the Fund
         on behalf of the  applicable  Portfolio for any action taken or omitted
         by it in good faith in reasonable  reliance upon such  instructions  or
         upon  the  opinion  of  such   counsel.   The  Bank,   its  agents  and
         subcontractors  shall be protected  and  indemnified  in acting in good
         faith upon any paper or document furnished by or on behalf of the Fund,
         reasonably believed to be genuine and to have been signed by the proper
         person or persons, or upon any instruction,  information, data, records
         or  documents  provided  the Bank or its  agents or  subcontractors  by
         machine  readable input,  telex,  CRT data entry or other similar means
         authorized  by the Fund,  and  shall not be held to have  notice of any
         change of  authority  of any person,  until  receipt of written  notice
         thereof from the Fund.  The Bank, its agents and  subcontractors  shall
         also be protected and  indemnified  in recognizing  stock  certificates
         which are  reasonably  believed to bear the proper  manual or facsimile
         signatures of the officers of the Fund, and the proper countersignature
         of any former transfer agent or former  registrar,  or of a co-transfer
         agent or co-registrar.

6.4      In order that the indemnification  provisions contained in this Section
         6 shall apply, upon the assertion of a claim for which either party may
         be required to indemnify the other,  the party seeking  indemnification
         shall promptly  notify the Fund of such  assertion,  and shall keep the
         other party advised with respect to all  developments  concerning  such
         claim. The party who may be required to indemnify shall have the option
         to participate with the party seeking indemnification in the defense of
         such  claim or to defend  against  said claim in its own name or in the
         name of the other party. The party seeking  indemnification shall in no
         case confess any claim or make any  compromise in any case in which the
         other  party may be  required  to  indemnify  it except  with the other
         party's prior written consent.

7.       Covenants of the Fund and the Bank

<PAGE>



7.2      The Bank  hereby  agrees  to  establish  and  maintain  facilities  and
         procedures  reasonably  acceptable to the Fund for safekeeping of stock
         certificates,  check forms and facsimile signature  imprinting devices,
         if any; and for the  preparation  or use,  and for keeping  account of,
         such certificates, forms and devices.

7.3      The Bank shall keep  records  relating to the  services to be performed
         hereunder,  in the form and  manner  as it may deem  advisable.  To the

         amended,  and the  Rules  thereunder,  the  Bank  agrees  that all such
         records  prepared or maintained by the Bank relating to the services to
         be  performed  by the Bank  hereunder  are the property of the Fund and
         will be preserved,  maintained  and made  available in accordance  with
         such Section and Rules, and will be surrendered promptly to the Fund on
         and in accordance with its request.

7.4      The Bank and the Fund agree that all books,  records,  information  and
         data  pertaining to the business of the other party which are exchanged
         or received  pursuant to the  negotiation  or the  carrying out of this
         Agreement  shall  remain  confidential,  and shall  not be  voluntarily
         disclosed to any other person, except as may be required by law.

7.5      In  case  of  any  requests  or  demands  for  the  inspection  of  the
         Shareholder  records of the Fund,  the Bank will endeavor to notify the
         Fund and to secure  instructions from an authorized officer of the Fund
         as to such inspection. The Bank reserves the right, however, to exhibit
         the  Shareholder  records to any person  whenever  it is advised by its
         counsel  that it may be held  liable for the  failure  to  exhibit  the
         Shareholder records to such person.

7.6      Notwithstanding  any other  provision  of this  Agreement,  the parties
         agree that the assets and liabilities of each Portfolio of the Fund are
         separate and  distinct  from the assets and  liabilities  of each other
         Portfolio and that no Portfolio shall be liable or shall be charged for
         any debt,  obligation  or  liability  of any other  Portfolio,  whether
         arising under this Agreement or otherwise.

8.       Termination of Agreement

8.1      This  Agreement  may be  terminated  by either  party upon one  hundred
         twenty (120) days written notice to the other.

8.2      Should the Fund  exercise  its right to  terminate,  all  out-of-pocket
         expenses  associated  with the movement of records and material will be
         borne  by  the  Fund  on   behalf  of  the   applicable   Portfolio(s).
         Additionally,  the Bank  reserves  the  right to  charge  for any other
         reasonable expenses associated with such termination.

         the Bank  shall be as  fully  responsible  to the Fund for the acts and
         omissions of any subcontractor as it is for its own acts and omissions.

11.      Amendment

         This  Agreement  may be  amended  or  modified  by a written  agreement
         executed by both parties and  authorized or approved by a resolution of
         the Trustees of the Fund.

         liable for  damages to the other for any  damages  resulting  from such

         WHEREAS,  N&B MANAGEMENT is the  administrator  and  distributor of the

         NOW,  THEREFORE,  in  consideration  of  their  mutual  promises,  LIFE
COMPANY, TRUST, MANAGERS TRUST and N&B MANAGEMENT agree as follows:

                         Article I. SALE OF TRUST SHARES

         1.1 TRUST agrees to make  available  to the  Separate  Accounts of LIFE
COMPANY shares of the selected Portfolios as listed on Appendix B for investment
of purchase payments of Variable Contracts  allocated to the designated Separate
Accounts as provided in TRUST's Prospectus.

         1.2 TRUST agrees to sell to LIFE  COMPANY  those shares of the selected
Portfolios of TRUST which LIFE COMPANY orders,  executing such orders on a daily
basis  at the net  asset  value  next  computed  after  receipt  by TRUST or its
designee of the order for the shares of TRUST. For purposes of this Section 1.2,
LIFE COMPANY shall be the designee of TRUST for receipt of such orders from LIFE
COMPANY and receipt by such designee shall constitute receipt by TRUST; provided
that TRUST receives  notice of such order by 9:30 a.m. New York time on the next
following  Business Day. "Business Day" shall mean any day on which the New York
Stock  Exchange is open for trading and on which TRUST  calculates its net asset
value pursuant to the rules of the SEC.

         1.3 TRUST agrees to redeem for cash,  on LIFE  COMPANY's  request,  any
full or fractional shares of TRUST held by LIFE COMPANY, executing such requests
on a daily basis at the net asset value next computed  after receipt by TRUST or
its  designee of the request for  redemption.  For purposes of this Section 1.3,
LIFE  COMPANY  shall be the  designee  of TRUST  for  receipt  of  requests  for
redemption  from LIFE  COMPANY and  receipt by such  designee  shall  constitute
receipt  by TRUST;  provided  that TRUST  receives  notice of such  request  for
redemption by 9:30 a.m. New York time on the next following Business Day.

         1.4 TRUST shall furnish, on or before the ex-dividend date,
notice to LIFE COMPANY of any income dividends or capital gain


                                                       

<PAGE>



distributions  payable on the shares of any  Portfolio  of TRUST.  LIFE  COMPANY
hereby   elects  to  receive  all  such  income   dividends   and  capital  gain
distributions as are payable on a Portfolio's shares in additional shares of the
Portfolio.  TRUST shall notify LIFE COMPANY of the number of shares so issued as
payment of such dividends and distributions.

         1.5 TRUST  shall  make the net asset  value per share for the  selected
Portfolio(s)  available to LIFE  COMPANY on a daily basis as soon as  reasonably
practicable  after the net asset value per share is calculated but shall use its
best efforts to make such net asset value  available by 6:30 p.m. New York time.
If TRUST provides LIFE COMPANY with  materially  incorrect share net asset value
information  through  no fault of LIFE  COMPANY,  LIFE  COMPANY on behalf of the
Separate  Accounts,  shall be entitled to an  adjustment to the number of shares
purchased or redeemed to reflect the correct share net asset value. Any material
error in the calculation of net asset value per share,  dividend or capital gain
information shall be reported promptly upon discovery to LIFE COMPANY.

         1.6 At the  end of  each  Business  Day,  LIFE  COMPANY  shall  use the
information  described in Section 1.5 to calculate  Separate Account unit values
for the day.  Using these unit  values,  LIFE  COMPANY  shall  process each such
Business  Day's  Separate  Account  transactions  based on requests and premiums
received  by it by the  close of  trading  on the  floor  of the New York  Stock
Exchange  (currently 4:00 p.m. New York time) to determine the net dollar amount
of TRUST shares  which shall be purchased or redeemed at that day's  closing net
asset value per share. The net purchase or redemption orders so determined shall
be  transmitted  to TRUST by LIFE  COMPANY  by 9:30  a.m.  New York  Time on the
Business Day next following LIFE COMPANY's receipt of such requests and premiums
in accordance with the terms of Sections 1.2 and 1.3 hereof.

         1.7 If LIFE COMPANY's order requests the purchase of TRUST shares, LIFE
COMPANY  shall pay for such  purchase  by wiring  federal  funds to TRUST or its
designated  custodial  account  on the  day the  order  is  transmitted  by LIFE
COMPANY.  If LIFE  COMPANY's  order  requests a net  redemption  resulting  in a
payment of redemption proceeds to LIFE COMPANY,  TRUST shall wire the redemption
proceeds to LIFE COMPANY by the next Business Day, unless doing so would require
TRUST to dispose of portfolio  securities or otherwise incur  additional  costs,
but in such event, proceeds shall be wired to LIFE COMPANY within seven days and
TRUST  shall  notify the  person  designated  in writing by LIFE  COMPANY as the
recipient  for such  notice of such  delay by 3:00  p.m.  New York Time the same
Business Day that LIFE COMPANY  transmits the redemption order to TRUST. If LIFE
COMPANY's  order  requests  the  application  of  redemption  proceeds  from the
redemption of shares to the purchase of shares of another fund  administered  or
distributed by N&B MANAGEMENT, TRUST


                                                       

<PAGE>



shall so apply such proceeds the same  Business Day that LIFE COMPANY  transmits
such order to TRUST.

         1.8 TRUST  agrees  that all shares of the  Portfolios  of TRUST will be
sold only to Participating  Insurance Companies which have agreed to participate
in TRUST to fund their Separate Accounts and/or to certain qualified pension and
other  retirement  plans,  all in accordance  with the  requirements  of Section
817(h) of the Internal  Revenue Code of 1986,  as amended  ("Code") and Treasury
Regulation 1.817-5.  Shares of the Portfolios of TRUST will not be sold directly
to the general public.

         1.9 TRUST may refuse to sell shares of any Portfolio to any person,  or
suspend or terminate  the offering of the shares of any Portfolio if such action
is required by law or by regulatory  authorities  having  jurisdiction or is, in
the sole discretion of the Board of Trustees of TRUST,  acting in good faith and
in light of its fiduciary  duties under federal and any  applicable  state laws,
deemed  necessary  and  in  the  best  interests  of the  shareholders  of  such
Portfolios.

other promotional  material  approved by TRUST or its designee,  except with the

                         Article V. POTENTIAL CONFLICTS

         5.1 The Board of Trustees of TRUST and  MANAGERS  TRUST (the  "Boards")
will monitor TRUST and MANAGERS TRUST, respectively, (collectively the "Funds"),
for the existence of any material  irreconcilable conflict between the interests
of the Variable  Contract owners of  Participating  Insurance  Company  Separate
Accounts  investing in the Funds. A material  irreconcilable  conflict may arise
for a variety of reasons,  including:  (a) state insurance  regulatory authority
action;  (b) a  change  in  applicable  federal  or  state  insurance,  tax,  or
securities laws or regulations,  or a public ruling,  private letter ruling,  or
any similar action by insurance, tax, or securities regulatory authorities;  (c)
an  administrative  or judicial  decision in any  relevant  proceeding;  (d) the
manner in which the investments of the Funds are being managed; (e) a difference
in voting  instructions  given by variable  annuity and variable life  insurance
contract  owners or by  contract  owners of  different  Participating  Insurance
Companies;  or (f) a decision by a Participating  Insurance Company to disregard
voting instructions of Variable Contract owners.

          5.2 LIFE  COMPANY will report any  potential or existing  conflicts to
the Boards.  LIFE COMPANY will be  responsible  for assisting  each  appropriate
Board in carrying out its responsibilities under the Conditions set forth in the
notice  issued  by the SEC for the  Funds  on  April  12,  1995  (the  "Notice")
(Investment Company Act Release No. 21003), which LIFE COMPANY has reviewed,  by
providing each appropriate Board with all information  reasonably  necessary for
it to consider any issues raised. This responsibility includes, but is not

                                                       

<PAGE>



limited  to, an  obligation  by LIFE  COMPANY to inform each  appropriate  Board
whenever  Variable  Contract owner voting  instructions  are disregarded by LIFE
COMPANY.  These  responsibilities  will be  carried  out with a view only to the
interests of the Variable Contract owners.

         5.3  If a  majority  of  the  Board  of a  Fund  or a  majority  of its
disinterested trustees or directors,  determines that a material  irreconcilable
conflict exists, affecting the LIFE COMPANY, LIFE COMPANY, at its expense and to
the extent reasonably  practicable (as determined by a majority of disinterested
trustees or directors), will take any steps necessary to remedy or eliminate the
irreconcilable  material  conflict,   including:   (a)  withdrawing  the  assets
allocable to some or all of the Separate  Accounts  from the Funds or any series
thereof and reinvesting those assets in a different investment medium, which may
include another series of TRUST or MANAGERS TRUST, or another investment company
or submitting the question as to whether such segregation  should be implemented
to a vote  of  all  affected  Variable  Contract  owners  and,  as  appropriate,
segregating the assets of any appropriate group (i.e.,  Variable Contract owners
of one or more  Participating  Insurance  Companies) that votes in favor of such
segregation,  or offering to the affected Variable Contract owners the option of
making  such  a  change;  and  (b)  establishing  a  new  registered  management
investment  company or managed separate  account.  If a material  irreconcilable
conflict  arises  because  of LIFE  COMPANY's  decision  to  disregard  Variable
Contract  owner voting  instructions,  and that  decision  represents a minority
position or would preclude a majority vote, LIFE COMPANY may be required, at the
election of the relevant Fund, to withdraw its Separate Account's  investment in
such  Fund,  and no  charge  or  penalty  will be  imposed  as a result  of such
withdrawal. The responsibility to take such remedial action shall be carried out
with a view only to the interests of the Variable Contract owners.

         For the purposes of this  Section 5.3, a majority of the  disinterested
members of the  applicable  Board shall  determine  whether or not any  proposed
action adequately remedies any irreconcilable material conflict, but in no event
will the relevant Fund or N&B MANAGEMENT (or any other investment adviser of the
Funds) be required to establish a new funding medium for any Variable  Contract.
Further,  LIFE COMPANY  shall not be required by this Section 5.3 to establish a
new  funding  medium for any  Variable  Contract  if any offer to do so has been
declined by a vote of a majority of Variable Contract owners materially affected
by the irreconcilable material conflict.

          5.4 Any Board's  determination  of the existence of an  irreconcilable
material  conflict  and its  implications  shall be made known  promptly  and in
writing to LIFE COMPANY.



                                                      

<PAGE>



         5.5 No less than annually, LIFE COMPANY shall submit to the Boards such
reports,  materials  or data as such Boards may  reasonably  request so that the
Boards  may  fully  carry  out  the  obligations  imposed  upon  them  by  these
Conditions. Such reports, materials, and data shall be submitted more frequently
if deemed appropriate by the applicable Boards.

                               Article VI. VOTING

         6.1 LIFE COMPANY will provide  pass-through  voting  privileges  to all
Variable  Contract  owners so long as the SEC continues to interpret the '40 Act
as requiring  pass-through  voting privileges for Variable Contract owners. This
condition will apply to UIT- Separate Accounts investing in TRUST and to managed
separate  accounts  investing in MANAGERS TRUST to the extent a vote is required
with respect to matters relating to MANAGERS TRUST.  Accordingly,  LIFE COMPANY,
where applicable,  will vote shares of a Fund held in its Separate Accounts in a
manner  consistent  with voting  instructions  timely received from its Variable
Contract owners.  LIFE COMPANY will be responsible for assuring that each of its
Separate  Accounts that participates in any Fund calculates voting privileges in
a manner  consistent  with other  participants  as defined in the Conditions set
forth  in the  Notice  ("Participants").  The  obligation  to  calculate  voting
privileges in a manner consistent with all other Separate Accounts  investing in
a Fund will be a contractual obligation of all Participants under the agreements
governing  participation  in the Funds.  Each  Participant  will vote shares for
which it has not received timely voting instructions, as well as shares it owns,
in the same  proportion  as its votes  those  shares  for which it has  received
voting instructions.

         6.2 If and to the extent  Rule 6e-2 and Rule  6e-3(T) are  amended,  or
Rule 6e-3 is adopted,  to provide exemptive relief from any provision of the '40
Act or the rules  thereunder  with respect to mixed and shared  funding on terms
and conditions  materially  different from any exemptions  granted in the Order,
then TRUST, MANAGERS TRUST and/or the Participants,  as appropriate,  shall take
such steps as may be  necessary  to comply with Rule 6e-2 and Rule  6e-3(T),  as
amended, and Rule 6e-3, as adopted, to the extent such Rules are applicable.

                          Article VII. INDEMNIFICATION

         7.1  Indemnification by LIFE COMPANY.  LIFE COMPANY agrees to indemnify
and hold  harmless  TRUST,  MANAGERS  TRUST,  N&B  MANAGEMENT  and each of their
Trustees, directors, officers, employees and agents and each person, if any, who
controls TRUST or MANAGERS TRUST or N&B MANAGEMENT within the meaning of Section
15 of the '33 Act (collectively,  the "Indemnified Parties" for purposes of this
Article VII) against any and all losses, claims, damages, liabilities

(including  amounts paid in settlement with the written consent of LIFE COMPANY,
which consent shall not be unreasonably withheld) or litigation (including legal
and other expenses),  to which the Indemnified  Parties may become subject under
any statute,  regulation,  at common law or  otherwise,  insofar as such losses,
claims,  damages,  liabilities  or expenses  (or actions in respect  thereof) or
settlements  are  related to the sale or  acquisition  of TRUST's  shares or the
Variable Contracts and:

     (a)  arise out of or are based upon any untrue statements or alleged untrue
          statements  of  any  material  fact  contained  in  the   Registration
          Statement or prospectus for the Variable Contracts or contained in the
          Variable  Contracts  (or any  amendment  or  supplement  to any of the
          foregoing),  or arise out of or are  based  upon the  omission  or the
          alleged  omission  to state  therein a material  fact  required  to be
          stated  therein  or  necessary  to make  the  statements  therein  not
          misleading,  provided that this agreement to indemnify shall not apply
          as to any  Indemnified  Party if such  statement  or  omission or such
          alleged  statement  or  omission  was  made in  reliance  upon  and in
          conformity with information  furnished to LIFE COMPANY by or on behalf
          of TRUST for use in the  registration  statement or prospectus for the
          Variable  Contracts or in the Variable  Contracts or sales  literature
          (or any  amendment or  supplement)  or otherwise for use in connection
          with the sale of the Variable Contracts or TRUST shares; or

     (b)  arise out of or as a result of  statements or  representations  (other
          than  statements  or  representations  contained  in the  registration
          statement,  prospectus  or sales  literature  of TRUST not supplied by
          LIFE  COMPANY,  or persons  under its control) or wrongful  conduct of
          LIFE COMPANY or persons under its control, with respect to the sale or
          distribution of the Variable Contracts or TRUST shares; or

     (c)  arise out of any untrue  statement  or alleged  untrue  statement of a
          material fact contained in a registration  statement,  prospectus,  or
          sales  literature  of TRUST or any  amendment  thereof  or  supplement
          thereto  or the  omission  or  alleged  omission  to state  therein  a
          material fact  required to be stated  therein or necessary to make the
          statements  therein not  misleading  if such  statement or omission or
          such alleged  statement  or omission was made in reliance  upon and in
          conformity with information furnished to TRUST by or on behalf of LIFE
          COMPANY; or
<PAGE>

                          
     (d)  arise as a result of any  failure  by LIFE  COMPANY  to  substantially
          provide the services and furnish the materials under the terms of this
          Agreement; or

     (e)  arise out of or result from any material breach of any  representation
          and/or warranty made by LIFE COMPANY in this Agreement or arise out of
          or result from any other  material  breach of this  Agreement  by LIFE
          COMPANY.

         7.2  LIFE  COMPANY  shall  not be  liable  under  this  indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
incurred or assessed  against an  Indemnified  Party as such may arise from such
Indemnified Party's willful  misfeasance,  bad faith, or gross negligence in the
performance of such Indemnified  Party's duties or by reason of such Indemnified
Party's  reckless  disregard of obligations or duties under this Agreement or to
TRUST, whichever is applicable.

         7.3  LIFE  COMPANY  shall  not be  liable  under  this  indemnification
provision  with  respect to any claim made against an  Indemnified  Party unless
such  Indemnified  Party shall have  notified  LIFE COMPANY in writing  within a
reasonable   time  after  the  summons  or  other  first  legal  process  giving
information  of the  nature  of the  claim  shall  have  been  served  upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify LIFE COMPANY of any
such claim shall not relieve LIFE COMPANY from any  liability  which it may have
to the Indemnified  Party against whom such action is brought  otherwise than on
account of this  indemnification  provision.  In case any such action is brought
against an Indemnified  Party,  LIFE COMPANY shall be entitled to participate at
its own  expense  in the  defense of such  action.  LIFE  COMPANY  also shall be
entitled to assume the defense thereof,  with counsel  satisfactory to the party
named in the  action.  After  notice  from LIFE  COMPANY  to such  party of LIFE
COMPANY's  election to assume the defense thereof,  the Indemnified  Party shall
bear the fees and expenses of any  additional  counsel  retained by it, and LIFE
COMPANY will not be liable to such party under this  Agreement  for any legal or
other expenses  subsequently  incurred by such party independently in connection
with the defense thereof other than reasonable costs of investigation.

         7.4  Indemnification  by  N&B  MANAGEMENT.  N&B  MANAGEMENT  agrees  to
indemnify and hold harmless  LIFE COMPANY and each of its  directors,  officers,
employees,  and agents and each person, if any, who controls LIFE COMPANY within
the  meaning  of  Section  15 of the '33  Act  (collectively,  the  "Indemnified
Parties" for the purposes

of this Article VII) against any and all losses,  claims,  damages,  liabilities
(including amounts paid in settlement with the written consent of N&B MANAGEMENT
which consent shall not be unreasonably withheld) or litigation (including legal
and other  expenses) to which the  Indemnified  Parties may become subject under
any statute, or regulation, at common law or otherwise,  insofar as such losses,
claims,  damages,  liabilities  or expenses  (or actions in respect  thereof) or
settlements  are  related to the sale or  acquisition  of TRUST's  shares or the
Variable Contracts and:

     (a)  arise out of or are based upon any untrue  statement or alleged untrue
          statement of any material fact contained in the registration statement
          or  prospectus  or sales  literature  of TRUST  (or any  amendment  or
          supplement to any of the foregoing), or arise out of or are based upon
          the omission or the alleged  omission to state therein a material fact
          required  to be stated  therein or  necessary  to make the  statements
          therein not  misleading,  provided  that this  agreement  to indemnify
          shall  not  apply as to any  Indemnified  Party if such  statement  or
          omission or such  alleged  statement  or omission was made in reliance
          upon and in conformity with information furnished to N&B MANAGEMENT or
          TRUST by or on  behalf  of LIFE  COMPANY  for use in the  registration
          statement  or  prospectus  for  TRUST or in sales  literature  (or any
          amendment or supplement)  or otherwise for use in connection  with the
          sale of the Variable Contracts or TRUST shares; or

     (b)  arise out of or as a result of  statements or  representations  (other
          than  statements  or  representations  contained  in the  registration
          statement,  prospectus or sales literature for the Variable  Contracts
          not  supplied  by N&B  MANAGEMENT  or persons  under its  control)  or
          wrongful  conduct of TRUST or N&B  MANAGEMENT  or persons  under their
          control,  with  respect to the sale or  distribution  of the  Variable
          Contracts or TRUST shares; or

     (c)  arise out of any untrue  statement  or alleged  untrue  statement of a
          material fact contained in a registration  statement,  prospectus,  or
          sales  literature  covering the Variable  Contracts,  or any amendment
          thereof or supplement  thereto or the omission or alleged  omission to
          state  therein  a  material  fact  required  to be stated  therein  or
          necessary  to make the  statements  therein  not  misleading,  if such
          statement or omission or such  alleged  statement or omission was made
          in reliance upon and in conformity with information  furnished to LIFE
          COMPANY for inclusion therein by or on behalf of TRUST; or

                                                      
<PAGE>

     (d)  arise as a result of (i) a failure by TRUST to  substantially  provide
          the  services  and  furnish  the  materials  under  the  terms of this
          Agreement;  or (ii) a failure  by a  Portfolio(s)  invested  in by the
          Separate  Account to comply with the  diversification  requirements of
          Section  817(h) of the  Code;  or (iii) a  failure  by a  Portfolio(s)
          invested  in by  the  Separate  Account  to  qualify  as a  "regulated
          investment company" under Subchapter M of the Code; or

     (e)  arise out of or result from any material breach of any  representation
          and/or  warranty made by N&B MANAGEMENT in this Agreement or arise out
          of or result from any other  material  breach of this Agreement by N&B
          MANAGEMENT.

         7.5 N&B  MANAGEMENT  shall not be  liable  under  this  indemnification
provision with respect to any losses, claims, damages, liabilities or litigation
to which an  Indemnified  Party  would  otherwise  be  subject by reason of such
Indemnified Party's willful  misfeasance,  bad faith, or gross negligence in the
performance of such Indemnified  Party's duties or by reason of such Indemnified
Party's reckless  disregard of obligations and duties under this Agreement or to
LIFE COMPANY.

          7.6 N&B  MANAGEMENT  shall not be liable  under  this  indemnification
provision  with  respect to any claim made against an  Indemnified  Party unless
such  Indemnified  Party shall have notified N&B  MANAGEMENT in writing within a
reasonable   time  after  the  summons  or  other  first  legal  process  giving
information  of the  nature  of the  claim  shall  have  been  served  upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated  agent),  but failure to notify N&B MANAGEMENT of
any such claim shall not relieve N&B MANAGEMENT  from any liability which it may
have to the Indemnified Party against whom such action is brought otherwise than
on account of this indemnification provision. In case any such action is brought
against the Indemnified Parties, N&B MANAGEMENT shall be entitled to participate
at its own expense in the defense thereof. N&B MANAGEMENT also shall be entitled
to assume the defense thereof,  with counsel  satisfactory to the party named in
the action.  After notice from N&B MANAGEMENT to such party of N&B  MANAGEMENT's
election to assume the defense  thereof,  the  Indemnified  Party shall bear the
fees and expenses of any additional  counsel  retained by it, and N&B MANAGEMENT
will not be liable to such  party  under this  Agreement  for any legal or other
expenses  subsequently  incurred by such party  independently in connection with
the defense thereof other than reasonable costs of investigation.

          shall be furnished by LIFE COMPANY,  said  termination to be effective
          ten days after  receipt  of notice  unless  TRUST  makes  available  a

     (e)  In the event  TRUST's  shares  are not  registered,  issued or sold in
          accordance with applicable state or federal law, or such law precludes
          the use of such shares as the underlying investment medium of Variable
          Contracts issued or to be issued by LIFE COMPANY. Termination shall be
          effective upon such occurrence without notice;

     (f)  At the option of TRUST if the Variable  Contracts  cease to qualify as
          annuity contracts or life insurance  contracts,  as applicable,  under
          the Code, or if TRUST reasonably  believes that the Variable Contracts
          may fail to so qualify. Termination shall be effective upon receipt of
          notice by LIFE COMPANY;

     (g)  At the option of LIFE  COMPANY,  upon  TRUST's  breach of any material
          provision  of this  Agreement,  which breach has not been cured to the
          satisfaction  of LIFE COMPANY  within ten days after written notice of
          such breach is delivered to TRUST;

     (h)  At the option of TRUST,  upon LIFE  COMPANY's  breach of any  material
          provision  of this  Agreement,  which breach has not been cured to the
          satisfaction  of TRUST  within ten days after  written  notice of such
          breach is delivered to LIFE COMPANY;

     (i)  At the option of TRUST, if the Variable  Contracts are not registered,
          issued or sold in accordance with applicable federal and/or state law.
          Termination  shall  be  effective  immediately  upon  such  occurrence
          without notice;

     (j)  In the event this  Agreement  is assigned  without  the prior  written
          consent of LIFE COMPANY,  TRUST,  MANAGERS  TRUST and N&B  MANAGEMENT,
          termination  shall  be  effective  immediately  upon  such  occurrence
          without notice.

          8.3  Notwithstanding  any  termination of this  Agreement  pursuant to
Section 8.2 hereof,  TRUST at its option may elect to continue to make available
additional  TRUST  shares,  as  provided  below,  for so long as  TRUST  desires
pursuant  to the  terms  and  conditions  of this  Agreement,  for all  Variable
Contracts  in effect on the  effective  date of  termination  of this  Agreement
(hereinafter  referred  to  as  "Existing  Contracts").   Specifically,  without
limitation,  if TRUST so elects to make additional TRUST shares  available,  the
owners of the Existing  Contracts or LIFE  COMPANY,  whichever  shall have legal
authority  to do so,  shall be permitted  to  reallocate  investments  in TRUST,
redeem  investments  in TRUST  and/or  invest  in  TRUST  upon  the  payment  of
additional premiums under the Existing Contracts.  In the event of a termination
of this Agreement pursuant to Section 8.2 hereof,  TRUST and N&B MANAGEMENT,  as
promptly as is practicable  under the  circumstances,  shall notify LIFE COMPANY
whether  TRUST  elects to continue  to make TRUST  shares  available  after such
termination.   If  TRUST  shares  continue  to  be  made  available  after  such
termination,  the  provisions  of this  Agreement  shall  remain in  effect  and
thereafter  either  TRUST or LIFE COMPANY may  terminate  the  Agreement,  as so
continued  pursuant  to this  Section  8.3,  upon sixty (60) days prior  written
notice to the other party.

         8.4 Except as necessary to implement  Variable Contract owner initiated
transactions,  or as  required  by state  insurance  laws or  regulations,  LIFE
COMPANY shall not redeem the shares  attributable to the Variable  Contracts (as
opposed to the shares attributable to LIFE COMPANY's assets held in the Separate
Accounts),  and LIFE COMPANY  shall not prevent  Variable  Contract  owners from
allocating  payments  to a  Portfolio  that was  otherwise  available  under the
Variable  Contracts,  until thirty (30) days after the LIFE  COMPANY  shall have
notified TRUST of its intention to do so.
