                             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 and organized on May 23,
1994. Each Portfolio  seeks its investment  objective by investing in accordance
with its  investment  objective and policies.  The  Portfolios are managed by NB
Management.

         Prior to May 1,  2000,  the  Portfolios  invested  through  a  two-tier
master/feeder  structure.  Rather than investing  directly in  securities,  each
Portfolio  invested  all  of  its  assets  in  another  fund  that  served  as a
corresponding  "master series." All of the master series were separate series of
an investment company named Advisers Managers Trust. The master series, in turn,
invested  in  portfolio  securities.  Effective  May  1,  2000,  the  Portfolios
converted to a conventional  one-tier  structure.  Each  Portfolio  redeemed its
investment  in its  corresponding  master  series in return for  delivery of the
series'  portfolio  securities,  at  current  net asset  value,  subject  to the
liabilities  of the master  series.  Accordingly,  each  Portfolio  received the
investment  securities of its  corresponding  master series and will continue to
hold portfolio securities directly.

         The following information  supplements the discussion in the Prospectus
of the investment objective,  policies and limitations of each Portfolio. Unless
otherwise specified,  those investment objectives,  policies and limitations are
not  fundamental  and may be changed by the  trustees of the Trust  ("Trustees")
without shareholder approval. The fundamental  investment  objectives,  policies
and  limitations  of a Portfolio may not be changed  without the approval of the
lesser of: (1) 67% of the total units of beneficial  interest  ("shares") of the
Portfolio  represented  at a meeting at which  more than 50% of the  outstanding
Portfolio shares are represented; or (2) a majority of the outstanding shares of
the Portfolio.  These percentages are required by the Investment  Company Act of
1940 ("1940 Act") and are referred to in this SAI as a "1940 Act majority vote."

Investment Policies and Limitations

         Each Portfolio has its own fundamental and  non-fundamental  investment
policies and limitations, as discussed below.

         For  purposes  of  the  investment  limitation  on  concentration  in a
particular  industry,  NB  Management  determines  the  "issuer"  of a municipal
obligation  that  is  not a  general  obligation  note  or  bond  based  on  the
obligation's  characteristics.  The most significant of these characteristics is
the source of funds for the  repayment of  principal  and payment of 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,  the issuer of the letter of credit or
the guarantee is considered an issuer of the obligation.  If an obligation meets
the quality  restrictions of a Portfolio  without credit support,  the Portfolio
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.  The Liquid
Asset Portfolio  determines the "issuer" of a municipal  obligation for purposes
of its policy on industry  concentration  in accordance  with the  principles of
Rule 2a-7 under the 1940 Act. Also for purposes of the investment  limitation on
concentration in a particular  industry,  both  mortgage-backed and asset-backed
securities are grouped together as a single industry and certificates of deposit
("CD") are interpreted to include similar types of time deposits.

         Except for the  limitation  on borrowing  and,  with respect to Limited
Maturity Bond Portfolio and Liquid Asset  Portfolio,  the limitation on illiquid
securities,  any maximum  percentage of  securities  or assets  contained in any
investment policy or limitation will not be considered to be exceeded unless the
percentage   limitation  is  exceeded  immediately  after,  and  because  of,  a
transaction by a Portfolio.  If events  subsequent to a transaction  result in a
Portfolio exceeding the percentage  limitation on borrowing,  as applicable,  or
illiquid  securities,  NB Management will take  appropriate  steps to reduce the
percentage of borrowings or the percentage held in illiquid  securities,  as may
be required by law, within a reasonable amount of time.

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

         1........Borrowing.  Each Portfolio may not borrow money, except that a
Portfolio  may (i) borrow money from banks for  temporary or emergency  purposes
and not for leveraging or investment  (except for International  Portfolio which
may borrow for leveraging or 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 Portfolio's  total assets,  the Portfolio  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   Portfolio  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
Portfolio from purchasing  futures  contracts or options  (including  options on
futures and foreign  currencies and forward  contracts but excluding  options or
futures  contracts on physical  commodities)  or from investing in securities of
any kind.

         For purposes of the limitations on  commodities,  the Portfolios do not
consider foreign currencies or forward contracts to be physical commodities.

         3........Diversification.  Each  Portfolio 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 Portfolio's  total assets would be invested in the securities of that issuer
or (ii)  the  Portfolio  would  hold  more  than 10% of the  outstanding  voting
securities of that issuer.

         4........Industry  Concentration.  Each  Portfolio 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) securities issued or guaranteed by the U.S. Government,  or its
agencies or  instrumentalities,  or (ii)  investments by all Portfolios  (except
Partners  Portfolio and  International  Portfolio) in certificates of deposit or
bankers' acceptances issued by domestic branches of U.S. banks.

         5........Lending.  Each Portfolio 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.  Each  Portfolio  may not  purchase  real estate
unless acquired as a result of the ownership of securities or  instruments,  but
this  restriction  shall not  prohibit a Portfolio  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.

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

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

         9........Investment through a Master/Feeder Structure.  Notwithstanding
any other investment policy, each 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.  Currently, the Portfolios
do  not  utilize  this  policy.  Rather,  each  Portfolio  invests  directly  in
securities.

         The following non-fundamental investment policies and limitations apply
to all Portfolios unless otherwise indicated.

         1........Borrowing.  (All Portfolios except  International  Portfolio).
Each Portfolio 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 Portfolio may not make any loans other
than securities loans.

         3........Margin   Transactions.   Each   Portfolio   may  not  purchase
securities on margin from brokers or other  lenders  except that a Portfolio may
obtain such short-term  credits as are necessary for the clearance of securities
transactions. For all Portfolios (except Liquid Asset Portfolio) 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.

         4........Illiquid  Securities.  Each  Portfolio  may not  purchase  any
security  if,  as a  result,  more  than 15% (10% in the  case of  Liquid  Asset
Portfolio) 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 Portfolio
has valued the securities,  such as repurchase  agreements maturing in more than
seven days.

         5........Investments in Any One Issuer.  (International  Portfolio). At
the close of each quarter of the Portfolio's  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, or securities
of another regulated investment company.

         (Liquid Asset Portfolio). The Portfolio may not purchase the securities
of any  one  issuer  (other  than  U.S.  Government  and  Agency  Securities  or
securities  subject to a guarantee issued by a non-controlled  person as defined
in  Rule  2a-7  under  the  1940  Act)  if,  as a  result,  more  than 5% of the
Portfolio's total assets would be invested in the securities of that issuer.

         6........Foreign   Securities.   (Guardian,   Partners,   and  Socially
Responsive  Portfolios).  These  Portfolios  may not invest more than 10% of the
value of their total assets in securities of foreign issuers, provided that this
limitation shall not apply to foreign  securities  denominated in U.S.  dollars,
including American Depositary Receipts ("ADRs").

         7........Pledging.  (Guardian Portfolio).  The Portfolio may not pledge
or  hypothecate  any of its  assets,  except  that the  Portfolio  may pledge or
hypothecate  up to 5% of its total assets in connection  with its entry into any
agreement or  arrangement  pursuant to which a bank furnishes a letter of credit
to  collateralize  a  capital  commitment  made  by the  Portfolio  to a  mutual
insurance company of which the Portfolio is a member.

         The other  Portfolios  are not  subject  to any  restrictions  on their
ability  to  pledge  or  hypothecate  assets  and may do so in  connection  with
permitted borrowings.

         8........Social Policy. (Socially Responsive Portfolio).  The Portfolio
may not  purchase  securities  of issuers who derive more than 5% of their total
revenue  from  alcohol,  tobacco,  gambling or weapons,  or that are involved in
nuclear power.

         In addition to the preceding  non-fundamental  investment  policies and
limitations, Liquid Asset Portfolio has adopted procedures pursuant to Rule 2a-7
under the 1940 Act which impose  certain  restrictions  and  limitations  on the
Portfolio's investments.

Temporary Defensive Positions

         For temporary  defensive  purposes,  each  Portfolio  (except  Socially
Responsive  and  International  Portfolios)  may  invest up to 100% of its total
assets in cash or cash  equivalents,  U.S.  Government  and  Agency  Securities,
commercial  paper,  other money market funds (except for Liquid Asset Portfolio)
and certain other money market  instruments,  as well as  repurchase  agreements
collateralized  by  the  foregoing.   Limited  Maturity  Bond,   Balanced  (debt
securities  portion) and Liquid Asset  Portfolios  may adopt shorter than normal
weighted  average  maturities  or  durations.  Yields  on these  securities  are
generally  lower than yields  available on the  lower-rated  debt  securities in
which Limited  Maturity Bond and Balanced  (debt  portion)  Portfolios  normally
invests.

         Any part of  Socially  Responsive  Portfolio's  assets may be  retained
temporarily  in investment  grade fixed income  securities  of  non-governmental
issuers,  U.S. Government and Agency Securities,  repurchase  agreements,  money
market  instruments,  commercial  paper,  and cash and cash  equivalents when NB
Management believes that significant  adverse market,  economic,  political,  or
other  circumstances  require  prompt  action to avoid  losses.  Generally,  the
foregoing temporary  investments for Socially Responsive  Portfolio are selected
with a concern for the social impact of each investment.

         For temporary defensive purposes, International Portfolio 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.  International
Portfolio  may also  invest in such  instruments  to  increase  liquidity  or to
provide collateral to be held in segregated accounts.

Rating Agencies

         Each  Portfolio  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.  Although
the Portfolios may rely on the ratings of any NRSRO, the Portfolios mainly refer
to ratings  assigned by S&P and  Moody's,  which are  described in Appendix A to
this SAI. The Portfolios may also invest in unrated  securities  that are deemed
comparable  in quality by NB  Management  to the rated  securities  in which the
Portfolios may permissibly invest.

Investment Insight

         Neuberger  Berman's  commitment  to its asset  management  approach  is
reflected in the more than $125 million the  organization's  employees and their
families have invested in the Neuberger Berman mutual funds.

         Limited Maturity Bond,  Balanced (debt  securities  portion) and Liquid
Asset  Portfolio are designed  with varying  degrees of risk and return based on
the  duration  and/or  maturity of each  Portfolio.  Duration  measures a bond's
exposure to interest rate risk.  Duration  incorporates  a bond's yield,  coupon
interest  payments,  final  maturity  and call  features  into one  measure.  In
general,  the longer you extend a bond's  duration,  the greater  its  potential
return and exposure to interest rate fluctuations.

         For example, Liquid Asset Portfolio is a money market fund with average
portfolio  maturity of up to 90 days.  Limited  Maturity Bond and Balanced (debt
securities  portion)  Portfolios  seek a higher income but can  experience  more
price  fluctuation.  Their portfolio of bonds has a maximum average  duration of
four years. A more detailed  discussion of each Portfolio follows. In all cases,
these Portfolios pursue attractive current income with varying levels of risk to
principal and differ according to their investment guidelines.  These guidelines
include  maturity or duration,  type of bonds,  and the credit  quality of these
bonds.

Growth, Mid-Cap Growth, and Balanced (equity securities portion) Portfolios

         Investment Program

         Invests in common stock of mid-capitalization companies that are in new
or  rapidly  evolving  industries.  Seeks  growth of  capital  by  investing  in
companies with financial strength,  above-average  growth of earnings,  earnings
that  have  exceeded  analysts'  expectations,  a strong  position  relative  to
competitors and a stock price that is reasonable in light of its growth rate.

         Mid-Cap Growth Stock Investments

         The portfolio  co-mangers consider themselves growth stock investors in
the purest sense of the term. By that,  they mean they want to own the stocks of
companies that are growing  earnings faster than the average  American  business
and, ideally, faster than the competitors in their respective industries.  Their
exhaustive   research   efforts  are  focused  on  the  mid-cap   universe  and,
specifically, stocks that are in new or rapidly evolving industries. The kind of
fast-growth  companies the portfolio co-managers favor generally do not trade at
below  market  average  price-to-earnings  ratios.  However,  they do  look  for
companies trading at reasonable levels compared to their growth rates.

         An Intensive Research Effort

         The portfolio  co-managers love stock with positive earnings surprises.
Their  extensive  research has revealed  that mid-cap  stocks that have exceeded
Wall Street earnings  estimates have also tended to offer greater  potential for
long-term capital  appreciation.  To find these companies they scour the mid-cap
growth stock universe to isolate  stocks whose most recent  earnings have beaten
consensus  expectations.  Then,  the real work begins,  where  through  diligent
fundamental  research  they strive to identify  those  companies  most likely to
record a string of positive earnings surprises. Their ultimate goal is to invest
today in the fast growing  mid-sized  companies  that they believe are poised to
become tomorrow's Fortune 500.

         A Disciplined Sell Process

         "We are dispassionate  sellers," says one portfolio  co-manager.  "If a
stock  does  not  live up to our  earnings  expectations  or if we  believe  its
valuation  has become  excessive,  we will sell and direct the assets to another
opportunity we find more  attractive." A stock will also be sold when it reaches
its target price. They prefer to broadly diversify the portfolio's  assets among
many different  companies and industries  rather than heavily  concentrating its
holdings  in just a few of the  fastest  growing  industry  sectors.  This broad
diversification  helps to manage the overall  risk  inherent  in a portfolio  of
equity securities.

         Investors can expect:

o        Mid-cap growth stock investments
o        An intensive research effort
o        A disciplined sell process

         Investment Insight

         Without question, the portfolio co-managers are growth stock investors.
They  look for  companies  believed  capable  of  delivering  positive  earnings
surprises, particularly those with the potential to do so consistently. Ideally,
they seek to identify companies that will someday rank among the Fortune 500.

Guardian Portfolio

         Investment Program

         Seeks long term growth of capital  and,  secondarily,  current  income.
Invests  primarily  in stocks of  long-established  companies  considered  to be
undervalued in comparison to stocks of similar companies. Using a value-oriented
investment  approach  in  selecting  securities,  the  Portfolio  looks for such
factors  as  low   price-to-earnings   ratios,   strong  balance  sheets,  solid
management, and consistent earnings.

         Disciplined, Large-Cap Value Orientation

         As part  of its  stock  selection  process,  the  Portfolio  pursues  a
disciplined, value-driven investment style, which is Neuberger Berman's historic
strength.  Specifically,  the portfolio  co-managers  seek  large-capitalization
companies whose stock prices are substantially  undervalued.  Characteristics of
these firms may  include:  solid  balance  sheets,  above-average  returns,  low
valuations, and consistent earnings.

         Bottom-Up Approach to Stock Selection

         According  to one of  the  portfolio  co-managers,  "Cheap  stocks  are
plentiful,  but true investment  bargains are a rare find." To uncover them, the
portfolio co-managers scour a universe of stocks consisting of the bottom 20% of
the market in terms of  valuation.  Those deemed by the managers as  inexpensive
and  poised  for a  turnaround  are placed  under  consideration.  They look for
financially sound, well-managed companies that are undervalued relative to their
earnings potential and the market as a whole.

         A Broad View of Risk Management

         Managing risk involves  carefully  monitoring the way the stocks in the
portfolio react to one another as well as to outside factors. Companies that are
in completely different sectors may in fact react similarly to certain economic,
market  or   international   events.   In  their   efforts  to  consider   these
relationships,  the managers use quantitative analysis to evaluate these factors
and their  impact on the overall  portfolio.  It is a process  they believe is a
crucial  component  in  controlling  risk and one that  evolves over time as new
holdings are introduced to the portfolio.

         A Strong Sell Discipline

         The portfolio  co-managers will generally make an initial investment in
a stock of between 1-4% of total net assets. A higher  weighting  indicates that
they believe their research gives them an "edge" over Wall Street  analysts,  or
they  believe  the  stock  has  an  undiscovered  value  that  others  may  have
overlooked.  Once a stock grows  beyond the high side of that  range,  gains are
harvested and the holding is reduced to about 3% of total net assets.

o        Strong sell discipline

         Investment Insight

         The  portfolio   co-managers  look  for  established   companies  whose
intrinsic  value,  by their  measure,  is  undiscovered  among the  majority  of
investors. In managing overall risk, a conscious effort is made to determine the
risk/reward  scenario  of each  individual  holding as well as its impact at the
portfolio level.

International Portfolio

         Equity portfolios  consisting solely of domestic investments  generally
have not enjoyed the higher returns foreign  opportunities  can offer.  Over the
past thirty  years,  for  example,  the  average  growth  rates of many  foreign
economies  have  out-paced  that of the United  States.  While the United States
accounted for almost 66% of the world's total securities  market  capitalization
in 1970, it accounted for less than 51% of that total at the end of 1998.1

         Over time, a number of international  equity markets have  outperformed
their U.S. counterpart.  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,
nine of the ten largest steel companies, and eight of the ten largest electronic
and automobile companies are based outside the United States.

         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  and other
factors described in the Prospectus and this SAI. These include the prospects of
individual companies and other risks such as currency  fluctuations or controls,
expropriation, nationalization and confiscator taxation.

         Furthermore,  buying  foreign stocks and bonds can be difficult for the
individual investor and involves many decisions. Accessing international markets
is  complicated;  few  individuals  have  the  time  or  resources  to  evaluate
thoroughly  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.

         At least 65% of the  Portfolio's  total assets normally are invested in
equity securities of foreign issuers.  The Portfolio invests primarily in equity
securities of companies  located in developed foreign  economies,  as well as in
"emerging markets." NB Management's investment process includes a combination of
a top-down or macro-economic analysis and a bottom-up,  micro-economic approach,
as well as a blend of growth and value investment  styles. The Portfolio may use
leverage to facilitate transactions it enters into for hedging purposes.

         Investment Program

         Seeks  long-terms  growth of capital by  investing  primarily in common
stocks of  foreign  companies  of any  capitalization,  including  companies  in
developed  and emerging  industrialized  markets.  Investments  in  well-managed
companies that show potential for  above-average  growth or whose stock price is
undervalued.

         A combination of top-down and bottom-up approaches to investing.

         The portfolio  manager's top-down view of various regions and countries
helps her choose the areas that offer the best relative value. As she explained,
"We are value-added  investors,  not "Closet"  indexers.  We will overweight the
portfolio with  securities  from  countries we believe have the best  investment
potential and underweight those we think have limited  prospects." Her bottom-up
perspective  seeks  well-managed  companies  with strong  fundamentals,  such as
attractive cash flows,  strong balance sheets,  and solid earnings  growth.  The
Portfolio has no capitalization  constraints and thus can invest in companies of
all sizes.

         A Blend of Growth and Value Investment Styles

         The  portfolio  manager  uses a blend of styles to reduce  the risks of
significant  losses when a particular  style falls out of favor with  investors.
The growth component  highlights  rapidly growing  companies in niche industries
with  unique  products  or  services,  while  the  value  component  focuses  on
undervalued,   out-of-favor  companies  that  she  believes  are  poised  for  a
turnaround.

         High potential rewards with commensurate risks.

         The  Portfolio  invests  in equity  securities  of both  developed  and
emerging  markets.  While the potential  rewards are high, so are the associated
risks.  Foreign  markets are often less  developed and foreign  governments  and
economic  infrastructures  may  not be as  stable  compared  to the  U.S.  Other
international   risks,  such  as  currency  exchange  rate  and  interests  rate
fluctuations, could result in greater volatility than domestic funds.

         An added level of diversification.

         Domestic  and  foreign  markets  generally  do not all move in the same
direction  at the same time and are subject to different  sets of risk  factors.
Investors  with  exposure to more than a single  market can  potentially  offset
losses in one  market  with  gains in  another.  While  foreign  markets  can be
inherently  risky,  investors  who  include  international  securities  in their
portfolios can benefit from an additional  layer of  diversification  along with
the potential for long-term growth.

         Investment Insight

         In  identifying   attractive  stocks  from  among  the  many  thousands
currently  available  outside the U.S., it's important to have a clear strategy.
The  International  Portfolio uses a combination  of growth and value  criteria,
while also considering larger scale economic factors.

         Currency Risk Management

         Exchange  rate  movements  and  volatility  are  important  factors  in
international investing. The portfolio manager believes in actively managing the
Portfolio's  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.  The  portfolio  manager  uses  a
combination of economic  analysis to guide the Portfolio's  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.

         To illustrate the importance of including an international component in
a  well-diversified  portfolio,  below are the annual  returns for the S&P "500"
Index  and the  EAFE(R)  Index  for the  years  1985-1999.  In seven of the past
fifteen  years,  international  stocks (as  represented  by the EAFE Index) have
outperformed U.S. stocks (as represented by the S&P 500 Index), in some cases by
a significant margin. Conversely, in other years, U.S. stocks have substantially
outperformed  international stocks. Investors with exposure to both domestic and
international  issues can minimize losses because gains in one market can offset
losses in another.

         Of course,  these  historical  results may not  continue in the future.
Investors  should keep in mind the greater  risks  inherent in foreign  markets,
such as currency exchange fluctuations,  interest rates, and potentially adverse
economic and political conditions.

Limited Maturity Bond and Balanced (debt securities portion) Portfolios

         The Portfolios  seek the highest  available  current income  consistent
with liquidity and low risk to principal; total return is a secondary goal. They
invest in investment-grade  bonds and other debt securities from U.S. government
and corporate issuers.

         Investors can expect:

o        Actively managed portfolio duration
o        Credit selection with a value bias
o        Risk reduction through diversification

         Actively managed portfolio duration.  The portfolio co-managers attempt
to increase  income and preserve or enhance  total  return by actively  managing
average  portfolio  duration.  As one manager explains.  "Historically,  limited
maturity portfolios have been able to deliver much of the yield available in the
investment-grade  bond market with reduced  volatility." Of course,  there is no
assurance  that past results  will  continue in the future.  By keeping  average
duration at four years or less, the managers  attempt to reduce the higher level
of volatility  that is generally  associated with bonds of longer  duration.  In
general, the longer a security's duration,  the higher the yield and the greater
the volatility.

         Credit  selection with a value bias. As part of their credit  selection
process, the portfolio  co-managers monitor national trends in the corporate and
government  securities  markets,  including  a range of economic  and  financial
factors. Specifically, they look for short- to intermediate-term securities that
appear  underpriced  compared to bonds of similar structure and securities,  the
managers look for companies in sound  financial  condition  that may not be well
known to the majority of investors.

         Risk reduction through diversification.  In an attempt to reduce credit
risk,  the  portfolio  diversifies  among many  different  issuers  and types of
securities.  The portfolios invests mainly in  investment-grade  bonds and other
debt  securities  from U.S.  government and corporate  issuers.  In an effort to
enhance  yield  and add  diversification,  it may also  invest  up to 10% of net
assets in securities that are below investment-grade, provided that, at the time
of  purchase,  they are rated at least B by  Moody's or  Standard  & Poor's,  or
unrated securities managers believe,  "The incremental yield compensates for the
additional political and economic risks we take on." On occasion,  they may also
place a portion of assets in  foreign  securities,  which  could  cause  greater
movements in the fund's share price.

Liquid Asset Portfolio

         Liquid  Asset  Portfolio  seeks to provide  investors  with the highest
available current income consistent with safety and liquidity. In pursuit of its
objective,  the Portfolio invests in high-quality  U.S.-dollar denominated money
market  instruments.  The portfolio  co-managers  select  securities to maximize
yield, while seeking a stable $1.00 net asset value. They also broadly diversify
among a number and types of issuers to help limit risk.

Partners Portfolio

         Investment Program

         Invests  principally in common stocks of established  companies,  using
the  value-oriented  investment  approach.  Seeks  growth of capital  through an
investment  approach that is designed to increase  capital with reasonable risk.
Seeks securities believed to be undervalued based on strong fundamentals such as
a low price-to-earnings ratio, consistent cash flow, and a company's sound track
record through all phases of the market cycle.

         Undiscovered values in the mid- to large-cap area

         The portfolio co-managers comb the universe of mid- and large-cap stock
in  search  of  those  that  have  yet to be  "discovered"  by the  majority  of
investors.  They generally shy away from big, well-known  companies because they
believe  it is harder to gain a  competitive  edge in a stock that is covered by
many analysts. The managers prefer to focus their efforts outside of the Fortune
100, where they think many investment bargains abound.

         Strong companies at reasonable prices

         Like many of their  value-oriented  peers,  the  co-managers try to buy
quality  stocks  for  substantially  less than  their  estimated  market  value.
However,  they differ in their approach by applying another layer of analysis to
their value strategy.  For example,  in addition to searching for stocks trading
at below market  price-to-earnings  ratios,  they also focus on  companies  with
strong  fundamentals,  consistent  cash flows,  sound track records  through all
phases of the market  cycle and those  selling  at the low end of their  trading
ranges.  They are not interested in buying cheap stocks if they don't meet these
other measures of value as well.

         Solid Research

         The portfolio  co-managers  believe that through  "exhaustive  research
efforts,  good  companies  selling  for  less  than  their  true  worth  can  be
identified."  To  do  this  the  portfolio  co-managers  spend  a  lot  of  time
interviewing  senior company  managers.  Their  philosophy is that when they sit
across the table from a CEO or CFO and  question  him or her about the  company,
they get to know it quite well.  They find that there's simply no substitute for
that  kind of  firsthand  knowledge.  In  addition,  the  portfolio  co-managers
carefully examine a company's financial statements and contact its suppliers and
competitors.  While this type of analysis requires a lot of extra legwork,  they
believe it's worth the effort.

         Investment Insight

         The portfolio  co-managers  seek companies they believe are undervalued
relative to their  earnings  potential--where  there is a gap between the actual
price of a stock  and its  intrinsic  value in the  marketplace.  When a company
grows in value or the  valuation  gap closes,  the success of their  strategy is
realized.

Socially Responsive Portfolio

         Investment Program

         Seeks long-term capital appreciation  through investments  primarily in
securities of companies that meet both financial criteria and social policy. The
portfolio  co-managers  initially  screen  companies  using  a  value  investing
criteria,  then look for companies that show leadership in major areas of social
impact such as the environment, workplace diversity and employment.

         Financially sound companies with a social conscience

         The  portfolio  co-managers  look for the  stocks of mid- to  large-cap
companies  that first meet their  stringent  financial  criteria.  Their  social
screens are then  applied to these  stocks.  The ones  considered  worthy from a
financial  standpoint  are then  evaluated  using a  proprietary  database  that
develops and monitors  information on companies in various  categories of social
criteria.  Ideal investment candidates are companies that show leadership in the
areas  of  the   environment,   workplace   diversity  and   employment.   Other
considerations  are  based on  companies'  records  in other  areas of  concern,
including public health, type of products, and corporate citizenship.

         A traditional value approach

         The portfolio  co-managers'  initial financial screens select companies
using a traditional  value approach.  They look for  undervalued  companies with
solid  balance  sheets,  strong  management,  consistent  cash flows,  and other
value-related  factors,  such as low  price-to-earnings  and  low  price-to-book
ratios.   Their  value  approach  examines  these   price-to-earnings   and  low
price-to-book  ratios. Their value approach examines these companies,  searching
for those that may rise in price before  other  investors  realize  their worth.
They  strongly  believe  in helping  investors  put their  money to work,  while
supporting companies that follow principles of good corporate citizenship.

         An ever-evolving journey on the path to good corporate citizenship

         The  portfolio   co-managers  believe  that  most  socially  responsive
investors are not utopians.  They do not expect instant  perfection,  but rather
look for  signs  that a  company  is  evolving  and  moving  toward a  corporate
commitment to excellence.  As they put it, "Good corporate citizenship is one of
those things that is a journey,  not a  destination.  We've been working in this
field for some time,  and know that the social  records  of most  companies  are
written in shades of gray.  We are  pleased to see that more and more  companies
are coming to realize that change is a positive force for them."

         Investment Insight

         The portfolio  co-managers  believe that sound  practices in areas like
employment and the environment can have a positive impact on a company's  bottom
line. The look for companies that meet value-investing  criteria and also show a
commitment to uphold or improve their standards of corporate citizenship.

Additional Investment Information

         Some  or all of the  Portfolios,  as  indicated  below,  may  make  the
following  investments,  among others, some of which are part of the Portfolios'
principal  investment  strategies and some of which are not. The principal risks
of each Portfolio's  principal strategies are discussed in the Prospectus.  They
may  not  buy  all of the  types  of  securities  or use  all of the  investment
techniques that are described.  As used herein,  "Equity  Portfolios"  refers to
Balanced (equity securities portion), Growth, Guardian,  International,  Mid-Cap
Growth, Partners and Socially Responsive Portfolios.  "Income Portfolios" refers
to Balanced (debt securities  portion),  Limited Maturity Bond, and Liquid Asset
Portfolios.  Each  Equity  Portfolio  invests in a wide array of stocks,  and no
single  stock  makes up more  than a small  fraction  of any  Portfolio's  total
assets. Of course, each Portfolio's holdings are subject to change.

                                  * * *

         Illiquid   Securities.   (All  Portfolios).   Illiquid  securities  are
securities that cannot be expected to be sold within seven days at approximately
the price at which they are  valued.  These may  include  unregistered  or other
restricted  securities and repurchase  agreements maturing in greater than seven
days.  Illiquid  securities may also include commercial paper under section 4(2)
of the 1933 Act, as amended,  and Rule 144A  securities  (restricted  securities
that may be traded freely among  qualified  institutional  buyers pursuant to an
exemption from the  registration  requirements  of the securities  laws);  these
securities are considered  illiquid  unless NB  Management,  acting  pursuant to
guidelines established by the Trustees,  determines they are liquid.  Generally,
foreign  securities freely tradable in their principal market are not considered
restricted  or illiquid  even if they are not  registered  in the U.S.  Illiquid
securities  may be  difficult  for a Portfolio to value or dispose of due to the
absence of an active trading market. The sale of some illiquid securities by the
Portfolio  may be subject  to legal  restrictions  which  could be costly to the
Portfolio.

         Policies and  Limitations.  Each Portfolio may invest up to 15% (10% in
the case of Liquid Asset Portfolio) of its net assets in illiquid securities.

         Repurchase Agreements.  (All Portfolios).  In a repurchase agreement, a
Portfolio  purchases  securities  from a bank  that is a member  of the  Federal
Reserve System (or with respect to International Portfolio,  from a foreign bank
or a U.S. branch or agency of a foreign bank), or from a securities dealer, that
agrees to repurchase  the  securities  from the Portfolio at a higher price on a
designated future date.  Repurchase  agreements generally are for a short period
of time, usually less than a week. Costs,  delays, or losses could result if the
selling party to a repurchase  agreement becomes bankrupt or otherwise defaults.
NB  Management  monitors  the  creditworthiness  of  sellers.  If  International
Portfolio  enters  into a  repurchase  agreement  subject to foreign law and the
counter-party  defaults,  that Portfolio may not enjoy protections comparable to
those provided to certain  repurchase  agreements under U.S.  bankruptcy law and
may suffer delays and losses in disposing of the collateral as a result.

         Policies and Limitations. Repurchase agreements with a maturity of more
than seven days are considered to be illiquid securities. No Portfolio may enter
into a  repurchase  agreement  with a maturity  of more than seven days if, as a
result,  more than 15% (10% with respect to Liquid Asset Portfolio) of the value
of its net assets would then be invested in such repurchase agreements and other
illiquid  securities.  A Portfolio may enter into a repurchase agreement only if
(1) the  underlying  securities are of a type  (excluding  maturity and duration
limitations)  that the Portfolio's  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
repurchase  price,  and (3) payment for the  underlying  securities is made only
upon  satisfactory   evidence  that  the  securities  are  being  held  for  the
Portfolio's account by its custodian or a bank acting as the Portfolio's agent.

         Securities Loans. (All Portfolios).  Each Portfolio may lend securities
to banks, brokerage firms, or institutional  investors judged creditworthy by NB
Management,  provided that cash or equivalent collateral, equal to at least 100%
of the market value of the loaned securities,  is continuously maintained by the
borrower with the  Portfolio.  The Portfolio may invest the cash  collateral and
earn income,  or it may receive an agreed upon amount of interest  income from a
borrower who has delivered equivalent collateral. During the time securities are
on loan,  the  borrower  will pay the  Portfolio  an  amount  equivalent  to any
dividends  or  interest  paid on such  securities.  These  loans are  subject to
termination  at the option of the Portfolio or the  borrower.  The Portfolio 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 Portfolio  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.
NB 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.

         Policies and  Limitations.  Each Portfolio may lend  securities  with a
value not exceeding  33-1/3% of its total assets to banks,  brokerage  firms, or
other institutional  investors judged  creditworthy by NB Management.  Borrowers
are required  continuously to secure their  obligations to return  securities on
loan from a  Portfolio  by  depositing  collateral  in a form  determined  to be
satisfactory  by the Trustees.  The  collateral,  which must be marked to market
daily,  must be  equal  to at  least  100% of the  market  value  of the  loaned
securities,  which will also be marked to market  daily.  Securities  lending by
Socially Responsive Portfolio is not subject to the Social Policy.

         Restricted Securities and Rule 144A Securities. (All Portfolios).  Each
Portfolio 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. Before they are registered, such securities 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  market 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  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
Portfolio  qualify under Rule 144A,  and an  institutional  market  develops for
those securities, the Portfolio 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 Portfolio's illiquidity. NB Management, acting under guidelines established
by the Trustees,  may determine  that certain  securities  qualified for trading
under Rule 144A are liquid. Foreign securities that are freely tradable in their
principal  markets are not considered to be  restricted.  Regulation S under the
1933 Act permits the sale abroad of securities  that are not registered for sale
in the United States.

         Where registration is required, a Portfolio 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 Portfolio may be permitted to sell
a security under an effective registration statement.  If, during such a period,
adverse market  conditions  were to develop,  the Portfolio  might obtain a less
favorable  price than prevailed when it decided to sell.  Restricted  securities
for which no market  exists are  priced by a method  that the  Trustees  believe
accurately reflect fair value.

         Policies  and  Limitations.   To  the  extent  restricted   securities,
including Rule 144A securities, are illiquid,  purchases thereof will be subject
to each  Portfolio's  15% (10% in the case of Liquid Asset  Portfolio)  limit on
investments in illiquid securities.

         Commercial Paper.  (All  Portfolios).  Commercial paper is a short-term
debt security  issued by a  corporation,  bank,  municipality,  or other issuer,
usually for purposes such as financing  current  operations.  Each Portfolio may
invest in  commercial  paper  that  cannot be resold to the  public  without  an
effective registration statement under the 1933 Act. While restricted commercial
paper normally is deemed illiquid,  NB Management may in certain cases determine
that such paper is liquid, pursuant to guidelines established by the Trustees.

         Policies and Limitations.  Each Equity Portfolio normally may invest up
to 35% of its net assets in debt  securities,  including  commercial  paper. The
Equity  Portfolios  may invest in  commercial  paper only if it has received the
highest  rating from S&P (A-1) or Moody's (P-1) or is deemed by NB Management to
be of comparable quality.  International Portfolio may invest in such commercial
paper as a defensive measure, to increase liquidity, or as needed for segregated
accounts.  To  the  extent  restricted  commercial  paper  is  deemed  illiquid,
purchases  thereof will be subject to each  Portfolio's  15% (10% in the case of
Liquid Asset Portfolio) limit on investments in illiquid securities.

         Reverse  Repurchase   Agreements.   (All  Portfolios).   In  a  reverse
repurchase  agreement,  a Portfolio  sells portfolio  securities  subject to its
agreement  to  repurchase  the  securities  at a later  date  for a fixed  price
reflecting a market rate of interest. Reverse repurchase agreements may increase
fluctuations  in a  Portfolio's  net asset value  ("NAV") and may be viewed as a
form of leverage. There is a risk that the counter-party to a reverse repurchase
agreement will be unable or unwilling to complete the  transaction as scheduled,
which may  result  in  losses  to the  Portfolio.  NB  Management  monitors  the
creditworthiness of counterparties to reverse repurchase agreements.

         Policies and Limitations.  Reverse repurchase agreements are considered
borrowings for purposes of each Portfolio's  investment limitations and policies
concerning  borrowings.  While a reverse repurchase agreement is outstanding,  a
Portfolio  will  deposit in a  segregated  account  with its  custodian  cash or
appropriate  liquid  securities,  marked to market daily,  in an amount at least
equal to each Portfolio's obligations under the agreement.

         Banking and Savings  Institution  Securities.  (All Portfolios).  These
include CDs, time  deposits,  bankers'  acceptances,  and other  short-term  and
long-term debt obligations issued by commercial banks and 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.  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 Portfolio  invests
typically are not covered by deposit insurance.

         Policies and Limitations. Liquid Asset Portfolio may invest 25% or more
of its total assets in CDs or banker's  acceptances  issued by domestic branches
of U.S.  banks.  CDs are  interpreted to include similar types of time deposits.
The Portfolios 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 NB Management's approved list,
and (3) in the case of a foreign bank or institution,  the securities are, in NB
Management's  opinion,  of an  investment  quality  comparable  with  other debt
securities  that may be purchased by the  Portfolio.  These  limitations  do not
prohibit investments in securities issued by foreign branches of U.S. banks that
meet the foregoing requirements.

         Each Equity  Portfolio  will  normally  limit its  investments  in debt
securities,  including banking and savings  institution  securities,  to no more
than 35% of its total assets.

         Leverage. (International Portfolio). The Portfolio may make investments
when borrowings are  outstanding.  Leverage creates an opportunity for increased
net income but,  at the same time,  creates  special  risk  considerations.  For
example,  leveraging may amplify  changes in the Portfolio's  NAV.  Although the
principal of such borrowings will be fixed, the Portfolio's assets may change in
value during the time the  borrowing is  outstanding.  Leverage  from  borrowing
creates  interest  expenses for the Portfolio.  To the extent the income derived
from securities purchased with borrowed funds exceeds the interest the Portfolio
will have to pay, the Portfolio's net income will be greater than it would be if
leveraging  were not used.  Conversely,  if the income from the assets  obtained
with borrowed funds is not  sufficient to cover the cost of leveraging,  the net
income of the  Portfolio  will be less  than if  leveraging  were not used,  and
therefore the amount available for distribution to the Portfolio's  shareholders
as dividends will be reduced.

         Policies and Limitations.  Generally,  the Portfolio does not intend to
use leverage for investment purposes.  It may, however, use leverage to purchase
securities needed to close out short sales entered into for hedging purposes and
to facilitate other hedging  transactions.  Reverse repurchase agreements create
leverage  and  are  considered   borrowings  for  purposes  of  the  Portfolio's
investment limitations.

         Foreign Securities. (All Portfolios). Each Portfolio may invest in U.S.
dollar-denominated  securities issued by foreign issuers and foreign branches of
U.S. banks, including negotiable CDs, banker's acceptances and commercial paper.
Foreign issuers are issuers organized and doing business principally outside the
U.S.   and  include   banks,   non-U.S.   governments   and   quasi-governmental
organizations.

         While investments in foreign  securities are intended to reduce risk by
providing  further   diversification   (except  with  respect  to  International
Portfolio),  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,  nationalization,  expropriation,
or confiscatory  taxation) and the potentially adverse effects of unavailability
of public information regarding issuers, less 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 United
States.  It may be difficult to invoke legal  process or to enforce  contractual
obligations abroad.

         Each  Portfolio  (except  Liquid  Asset  Portfolio)  also may invest in
equity (except Limited Maturity Bond Portfolio), debt, or other income-producing
securities that are denominated in or indexed to foreign currencies,  including,
but not  limited  to (1)  common  and  preferred  stocks,  with  respect  to all
Portfolios  except Limited Maturity Bond Portfolio,  (2) CDs,  commercial paper,
fixed-time  deposits,  and bankers'  acceptances  issued by foreign  banks,  (3)
obligations of other corporations,  and (4) obligations of foreign  governments,
or their subdivisions, agencies, and instrumentalities,  international agencies,
and supranational entities. Investing in foreign currency denominated securities
includes  the special  risks  associated  with  investing  in  non-U.S.  issuers
described in the  preceding  paragraph and the  additional  risks of (1) adverse
changes in foreign  exchange  rates,  and (2) adverse  changes in  investment or
exchange control  regulations  (which could prevent cash from being brought back
to the United States).  Additionally,  dividends and interest payable on foreign
securities (and gains realized on disposition thereof) 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 Portfolio endeavors to achieve the most favorable
net results on portfolio transactions.

         Foreign  securities  often trade with less frequency and in less volume
than domestic  securities and 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.  Delays in  settlement  could result in
temporary  periods when a portion of the assets of a Portfolio is uninvested and
no return is earned  thereon.  The  inability  of a Portfolio  to make  intended
security  purchases due to settlement  problems  could cause a Portfolio to miss
attractive   investment   opportunities.   Inability  to  dispose  of  portfolio
securities  due to  settlement  problems  could  result  either  in  losses to a
Portfolio due to subsequent declines in value of the portfolio  securities,  or,
if a Portfolio has entered into a contract to sell the securities,  could result
in possible liability to the purchaser.

         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.
Individual  foreign  economies may differ favorably or unfavorably from the U.S.
economy in such respects as gross national product,  rate of inflation,  capital
reinvestment, resource self-sufficiency and balance of payments position.

         The  Portfolios   (except  Liquid  Asset  and  Limited   Maturity  Bond
Portfolios)  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  sponsored  ADRs,  but  not  unsponsored  ADRs,  are
contractually  obligated to disclose material  information in the United States.
Therefore,  the market value of  unsponsored  ADRs may not reflect the effect of
such information. 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.

         Policies  and  Limitations.  In order to limit  the risks  inherent  in
investing  in  foreign  currency   denominated   securities,   Balanced  (equity
securities  portion),  Growth,  Guardian,   Partners,  and  Socially  Responsive
Portfolios may not purchase any such security if, as a result,  more than 10% of
its total assets (taken at market  value) would be invested in foreign  currency
denominated  securities.  Limited  Maturity  Bond  Portfolio  may  not  purchase
securities  denominated  in or indexed to foreign  currencies,  if, as a result,
more than 25% of its total assets  (taken at market  value) would be invested in
such  securities.  Mid-Cap Growth  Portfolio may not purchase  foreign  currency
denominated securities if, as a result, more than 20% of its total assets (taken
at market value) would be invested in such securities. Within those limitations,
however,  no Portfolio is  restricted  in the amount it may invest in securities
denominated  in  any  one  foreign  currency.  International  Portfolio  invests
primarily  in  foreign  securities.  Liquid  Asset  Portfolio  may not invest in
foreign currency-denominated securities.

         Investments  in  securities  of  foreign  issuers  are  subject to each
Portfolio's  quality,  and, with respect to the Income Portfolios,  maturity and
duration standards.  Each Portfolio (except International  Portfolio) may invest
only in  securities of issuers in countries  whose  governments  are  considered
stable by NB Management.

         Japanese Investments.  (International Portfolio). All of the Portfolios
may invest in foreign securities, including securities of Japanese issuers. From
time to time  International  Portfolio may invest a  significant  portion of its
assets in securities of Japanese  issuers.  The performance of the Portfolio may
therefore be significantly  affected by events  influencing 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 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.  Japan's  economic  prospects  may be affected by the
political and military situations of its near neighbors, notably North and South
Korea, China and Russia.

         Variable or  Floating  Rate  Securities;  Demand and Put  Features  and
Guarantees.  (All  Portfolios).  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 a specified interest rate or index changes.  The interest
rate on variable and floating rate securities  (collectively,  "Adjustable  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.

         Adjustable  Rate  Securities  frequently  permit  the  holder to demand
payment of the  obligations'  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,  some Adjustable Rate Securities might not meet the quality
standards applicable to obligations purchased by the Portfolio.  Accordingly, in
purchasing   these   securities,   each  Portfolio   relies   primarily  on  the
creditworthiness of the credit instrument issuer or the insurer. A Portfolio can
also buy fixed rate  securities  accompanied by demand  features or put options,
permitting  the Portfolio to sell the security to the issuer or third party at a
specified  price.  A Portfolio  may rely on the  creditworthiness  of issuers of
credit enhancements in purchasing these securities.

         Among the Adjustable  Rate  Securities in which Liquid Asset  Portfolio
may invest are so-called  guaranteed  investment  contracts  ("GICs")  issued by
insurance  companies.  In the  event  of  insolvency  of the  issuing  insurance
company,  the ability of the  Portfolio  to recover its assets may depend on the
treatment of GICs under state insurance laws.

         Policies  and  Limitations.  Except  for  Liquid  Asset  Portfolio,  no
Portfolio  may 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. For
purposes of this  limitation,  each Portfolio  except for Liquid Asset Portfolio
excludes  securities that do not rely on the credit  instrument or insurance for
their  ratings,  i.e.,  stand on their own credit.  Liquid Asset  Portfolio  may
invest in  securities  subject to demand  features or guarantees as permitted by
Rule 2a-7 under the 1940 Act.  Each Equity  Portfolio  normally may invest up to
35% of its total assets in debt securities,  including variable or floating rate
securities.

         For  purposes of  determining  its  dollar-weighted  average  maturity,
Liquid  Asset  Portfolio  calculates  the  remaining  maturity of  variable  and
floating  rate  instruments  as  provided  in Rule 2a-7  under the 1940 Act.  In
calculating its  dollar-weighted  average maturity and duration,  a Portfolio is
permitted to treat  certain  Adjustable  Rate  Securities  as maturing on a date
prior to the date on which principal must  unconditionally  be paid. In applying
such maturity shortening  devices, NB Management  considers whether the interest
rate reset is expected to cause the security to trade at  approximately  its par
value.

         GICs are generally  regarded as illiquid.  Thus, Liquid Asset Portfolio
may not  invest in such GICs if, as a result,  more than 10% of the value of its
net assets would then be invested in such GICs and other illiquid securities.

         Mortgage-Backed   Securities.   (Income  Portfolios).   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  such as the GNMA,  Fannie Mae, and
Freddie Mac, though not  necessarily  backed by the full faith and credit of the
United  States,  or may be  issued  by  private  issuers.  Private  issuers  are
generally  originators  of and investors in mortgage  loans and include  savings
associations,  mortgage  bankers,  commercial  banks,  investment  bankers,  and
special purpose entities. Private mortgage-backed securities may be supported by
U.S.   Government   Agency   mortgage-backed   securities   or   some   form  of
non-governmental 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 market 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.

         Because  many  mortgages  are repaid  early,  the actual  maturity  and
duration of  mortgage-backed  securities are typically shorter than their stated
final maturity and their duration  calculated  solely on the basis of the stated
life and payment schedule.  In calculating its dollar-weighted  average maturity
and duration, a Portfolio may apply certain industry  conventions  regarding the
maturity and duration of  mortgage-backed  instruments.  Different  analysts use
different models and assumptions in making these determinations.  The Portfolios
use an  approach  that NB  Management  believes  is  reasonable  in light of all
relevant  circumstances.  If this determination is not borne out in practice, it
could  positively  or negatively  affect the value of the Portfolio  when market
interest rates change.  Increasing  market interest rates  generally  extend the
effective maturities of mortgage-backed securities, increasing their sensitivity
to interest rate changes.

         Mortgage-backed  securities may be issued in the form of collateralized
mortgage obligations ("CMOs") or collateralized  mortgage-backed bonds ("CBOs").
CMOs are obligations that are 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.  CBOs are general  obligations of the issuer
that are 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 or the duration of
a CMO but not that of a CBO (although,  like many bonds, CBOs may be callable by
the issuer prior to maturity).  To the extent that rising  interest  rates cause
prepayments  to occur at a slower than  expected  rate, a CMO could be converted
into a longer-term security that is subject to greater risk of price volatility.

         Governmental,   government-related,   and  private  entities  (such  as
commercial banks,  savings  institutions,  private mortgage insurance companies,
mortgage  bankers,  and other secondary  market issuers),  including  securities
broker-dealers and special purpose entities that generally are affiliates of the
foregoing established to issue such securities may create mortgage loan pools to
back CMOs and CBOs. 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.  Various forms of
insurance or guarantees,  including  individual  loan,  title,  pool, and hazard
insurance,  and letters of credit,  may support  timely  payment of interest and
principal of non-governmental  pools. The insurance and guarantees are issued by
governmental entities, private insurers, and the mortgage poolers. NB Management
considers such insurance and guarantees,  as well as the creditworthiness of the
issuers  thereof,  in  determining  whether a  mortgage-backed  security meets a
Portfolio's  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  Portfolio  may  buy  mortgage-backed
securities without insurance or guarantees, if NB Management determines that the
securities  meet  the  Portfolio's   quality  standards.   NB  Management  will,
consistent with the Portfolio's investment objectives,  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.

         Policies and Limitations.  A Portfolio may not purchase mortgage-backed
securities that, in NB Management's  opinion, are illiquid if, as a result, more
than  15%  (10% in the  case of  Liquid  Asset  Portfolio)  of the  value of the
Portfolio's net assets would be invested in illiquid securities.

         Dollar  Rolls.  (Limited  Maturity Bond and Balanced  (debt  securities
portion)  Portfolios).  In a "dollar  roll",  a Portfolio  sells  securities for
delivery  in  the  current  month  and   simultaneously   agrees  to  repurchase
substantially  similar  (i.e.,  same type and coupon)  securities on a specified
future date from the same party.  During the period before the  repurchase,  the
Portfolio  forgoes  principal  and  interest  payments  on the  securities.  The
Portfolio 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.  Dollar
rolls may increase fluctuations in a Portfolio's NAV and may be viewed as a form
of leverage.  A "covered roll" is a specific type of dollar roll for which there
is an offsetting  cash position or a  cash-equivalent  securities  position that
matures (or can be sold and settled) on or before the forward settlement date of
the  dollar  roll  transaction.  There is a risk that the  counterparty  will be
unable or unwilling to complete the  transaction as scheduled,  which may result
in losses to the  Portfolio.  NB  Management  monitors the  creditworthiness  of
counterparties to dollar rolls.

         Policies and  Limitations.  Dollar rolls are considered  borrowings for
purposes of each  Portfolio's  investment  policies and  limitations  concerning
borrowings.

         Forward   Commitments   (International   Portfolio)   and   When-Issued
Securities. (International, Limited Maturity Bond, and Balanced (debt securities
portion) Portfolios).  The Portfolios may purchase securities  (including,  with
respect  to  Limited  Maturity  Bond and  Balanced  Portfolios,  mortgage-backed
securities  such as  GNMA,  Fannie  Mae,  and  Freddie  Mac  certificates)  on a
when-issued basis and International Portfolio may purchase or sell securities on
a  forward  commitment  basis.  These  transactions  involve a  commitment  by a
Portfolio to purchase or sell securities at a future date (ordinarily within two
months  although the Portfolios may agree to a longer  settlement  period).  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
Portfolio to "lock in" what NB Management  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,  International  Portfolio  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 Portfolio 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.
If the seller fails to complete the sale, the Portfolio may lose the opportunity
to obtain a favorable price.

         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 Portfolio's  NAV starting on the date of the agreement to
purchase  the  securities.  Because  the  Portfolio  has  not yet  paid  for the
securities,  this produces an effect  similar to leverage.  A Portfolio does not
earn interest on the securities it has committed to purchase until they are paid
for and delivered on the settlement date. When  International  Portfolio makes a
forward  commitment to sell securities it owns, the proceeds to be received upon
settlement are included in the  Portfolio's  assets.  Fluctuations in the market
value of the underlying  securities are not reflected in the  Portfolio's NAV as
long as the commitment to sell remains in effect.

         Policies and  Limitations.  A Portfolio  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 Portfolio may dispose of or  renegotiate  a commitment  after it has
been entered  into. A Portfolio  also may sell  securities  it has  committed to
purchase  before  those  securities  are  delivered  to  the  Portfolio  on  the
settlement  date. A Portfolio  may realize a capital gain or loss in  connection
with these transactions.

         When a Portfolio  purchases  securities on a when-issued basis, it will
deposit,  in a segregated  account with its  custodian,  until  payment is made,
appropriate  liquid securities having a value (determined  daily) at least equal
to the amount of the Portfolio's purchase commitments.  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 Portfolio  will
maintain  sufficient  assets  at  all  times  to  cover  its  obligations  under
when-issued purchases and forward commitment transactions.

        Futures, Options on Futures, Options on Securities and Indices,
                   Forward Contracts, and Options on Foreign
               Currencies (collectively, "Financial Instruments")

         Futures  Contracts  and Options  Thereon.  (The Equity  Portfolios  and
Limited Maturity Bond and Balanced (debt securities portion)  Portfolios).  Each
of Socially  Responsive  and Mid-Cap  Growth  Portfolios  may  purchase and sell
interest rate futures  contracts,  stock and bond index futures  contracts,  and
foreign currency futures  contracts and may purchase and sell options thereon in
an attempt to hedge against  changes in the prices of securities or, in the case
of foreign  currency  futures and options  thereon,  to hedge against changes in
prevailing  currency  exchange  rates.  Because the futures  markets may be more
liquid  than  the  cash  markets,  the use of  futures  contracts  permits  each
Portfolio  to enhance  portfolio  liquidity  and  maintain a defensive  position
without having to sell portfolio securities. These Portfolios view investment in
(i) interest rate and securities index futures and options thereon as a maturity
management  device and/or a device to reduce risk or preserve total return in an
adverse environment for the hedged securities, and (ii) foreign currency futures
and options  thereon as a means of  establishing  more  definitely the effective
return  on,  or  the  purchase  price  of,  securities  denominated  in  foreign
currencies that are held or intended to be acquired by the Portfolio.

         Limited Maturity Bond and Balanced (debt securities portion) Portfolios
may purchase and sell interest rate and bond index futures contracts and options
thereon,  and may purchase  and sell  foreign  currency  futures  contracts  and
options  thereon  in an  attempt  to hedge  against  changes  in the  prices  of
securities or, in the case of foreign currency  futures and options thereon,  to
hedge against changes in prevailing currency exchange rates. Because the futures
markets may be more liquid than the cash markets,  the use of futures  permits a
Portfolio  to enhance  portfolio  liquidity  and  maintain a defensive  position
without having to sell portfolio  securities.  The Portfolios view investment in
(1) interest  rate and bond index  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 for the hedged securities and (2)
foreign  currency  futures and options thereon as a means of  establishing  more
definitely  the  effective  return  on, or the  purchase  price  of,  securities
denominated  in  foreign  currencies  held or  intended  to be  acquired  by the
Portfolios.

         International Portfolio may enter into futures contracts on currencies,
debt  securities,  interest  rates,  and  securities  indices that are traded on
exchanges  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 to the
rules of such foreign exchange.

         International Portfolio may sell futures contracts in order to offset a
possible  decline  in the  value of its  portfolio  securities.  When a  futures
contract is sold by the  Portfolio,  the value of the contract will tend to rise
when the value of the portfolio  securities  declines and will tend to fall when
the value of such  securities  increases.  The  Portfolio  may purchase  futures
contracts in order to fix what NB  Management  believes to be a favorable  price
for  securities  the  Portfolio  intends to purchase.  If a futures  contract is
purchased  by the  Portfolio,  the  value of the  contract  will  tend to change
together  with  changes  in the  value of such  securities.  To  compensate  for
differences in historical volatility between positions  International  Portfolio
wishes to hedge and the  standardized  futures  contracts  available  to it, the
Portfolio may purchase or sell futures  contracts with a greater or lesser value
than the securities it wishes to hedge.

         With respect to currency  futures,  International  Portfolio may sell a
futures  contract  or a call  option,  or it may  purchase  a put option on such
futures  contract,  if NB  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 portfolio securities denominated in that currency. If NB Management
anticipates that a particular  currency will rise,  International  Portfolio may
purchase a currency  futures  contract  or a call  option to protect  against an
increase in the price of securities  which are  denominated in that currency and
which the  Portfolio  intends to purchase.  The  Portfolio  may also  purchase a
currency futures contract or a call option thereon for non-hedging purposes when
NB 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 Portfolio.

         For the purposes of managing cash flow, each Portfolio may purchase and
sell stock index futures contracts, and may purchase and sell options thereon to
increase its exposure to the performance of a recognized  securities index, such
as the S&P 500 Index.

         A "sale" of a futures contract (or a "short" futures  position) entails
the assumption of a contractual obligation to deliver the securities or currency
underlying  the  contract at a specified  price at a specified  future  time.  A
"purchase"  of a futures  contract (or a "long"  futures  position)  entails the
assumption  of a contractual  obligation  to acquire the  securities or currency
underlying the contract at a specified price at a specified future time. Certain
futures,  including  stock and bond  index  futures,  are  settled on a net cash
payment basis rather than by the sale and delivery of the securities  underlying
the futures.

         U.S. futures  contracts (except certain currency futures) are traded on
exchanges that have been designated as "contract  markets" by the CFTC;  futures
transactions  must be executed through a futures  commission  merchant that is a
member of the relevant  contract market.  In both U.S. and foreign  markets,  an
exchange's  affiliated  clearing  organization  guarantees  performance  of  the
contracts between the clearing members of the exchange.

         Although  futures  contracts  by their  terms may  require  the  actual
delivery or acquisition of the underlying  securities or currency, in most cases
the contractual obligation is extinguished by being offset before the expiration
of the  contract.  A futures  position is offset by buying (to offset an earlier
sale) or selling (to offset an earlier  purchase) an identical  futures contract
calling for  delivery  in the same  month.  This may result in a profit or loss.
While futures  contracts  entered into by a Portfolio will usually be liquidated
in this manner,  the  Portfolio  may instead make or take delivery of underlying
securities whenever it appears economically advantageous for it to do so.

         "Margin"  with  respect to a futures  contract  is the amount of assets
that must be  deposited  by a Portfolio  with,  or for the benefit of, a futures
commission  merchant in order to initiate and maintain the  Portfolio's  futures
positions.  The  margin  deposit  made by the  Portfolio  when it enters  into a
futures contract ("initial margin") is intended to assure its performance of the
contract.  If the price of the futures contract changes -- increases in the case
of a short  (sale)  position  or  decreases  in the  case  of a long  (purchase)
position  -- so that the  unrealized  loss on the  contract  causes  the  margin
deposit not to satisfy  margin  requirements,  the Portfolio will be required to
make an additional margin deposit  ("variation  margin").  However, if favorable
price  changes in the futures  contract  cause the margin  deposit to exceed the
required  margin,  the excess will be paid to the Portfolio.  In computing their
NAVs, the Portfolios  mark to market the value of their open futures  positions.
Each Portfolio also must make margin deposits with respect to options on futures
that it has  written  (but not with  respect to  options on futures  that it has
purchased).  If the futures commission  merchant holding the margin deposit goes
bankrupt,  the Portfolio  could suffer a delay in recovering its funds and could
ultimately suffer a loss.

         An option on a futures  contract  gives the  purchaser  the  right,  in
return for the  premium  paid,  to assume a  position  in the  contract  (a long
position if the option is a call and a short position if the option is a put) at
a specified  exercise price at any time during the option exercise  period.  The
writer of the  option  is  required  upon  exercise  to  assume a short  futures
position (if the option is a call) or a long futures  position (if the option is
a put).  Upon  exercise  of the  option,  the  accumulated  cash  balance in the
writer's  futures margin account is delivered to the holder of the option.  That
balance  represents the amount by which the market price of the futures contract
at exercise  exceeds,  in the case of a call,  or is less than, in the case of a
put, the exercise price of the option.  Options on futures have  characteristics
and risks similar to those of securities options, as discussed herein.

         Although each Portfolio believes that the use of futures contracts will
benefit  it, if NB  Management's  judgment  about the general  direction  of the
markets or about  interest  rate or currency  exchange rate trends is incorrect,
the  Portfolio's  overall  return would be lower than if it had not entered into
any  such  contracts.  Further,  an  appropriate  futures  contract  may  not be
available even if the portfolio  manager wishes to enter into one. The prices of
futures contracts are volatile and are influenced by, among other things, actual
and anticipated  changes in interest or currency  exchange rates,  which in turn
are affected by fiscal and monetary  policies and by national and  international
political and economic  events.  At best,  the  correlation  between  changes in
prices  of  futures  contracts  and of  securities  being  hedged  can  be  only
approximate  due to differences  between the futures and  securities  markets or
differences  between the  securities  or  currencies  underlying  a  Portfolio's
futures  position  and  the  securities  held  by  or to be  purchased  for  the
Portfolio.  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  approaches
maturity.

         Because of the low margin deposits  required,  futures trading involves
an extremely  high degree of  leverage;  as a result,  a relatively  small price
movement in a futures contract may result in immediate and substantial  loss, or
gain, to the investor.  Losses that may arise from certain futures  transactions
are potentially unlimited.

         Most U.S.  futures  exchanges  limit the amount of  fluctuation  in the
price of a futures  contract or option thereon during a single trading day; once
the daily limit has been  reached,  no trades may be made on that day at a price
beyond  that  limit.  The daily  limit  governs  only price  movements  during a
particular  trading day,  however;  it thus does not limit potential  losses. In
fact,  it may  increase the risk of loss,  because  prices can move to the daily
limit for several  consecutive  trading days with little or no trading,  thereby
preventing   liquidation  of  unfavorable  futures  and  options  positions  and
subjecting traders to substantial losses. If this were to happen with respect to
a position held by a Portfolio, it could (depending on the size of the position)
have an adverse impact on the NAV of the Portfolio.

         Policies  and  Limitations.  Socially  Responsive  and  Mid-Cap  Growth
Portfolio each may purchase and sell futures contracts and may purchase and sell
options  thereon  in an  attempt  to hedge  against  changes  in the  prices  of
securities or, in the case of foreign currency  futures and options thereon,  to
hedge against prevailing currency exchange rates. These Portfolios do not engage
in  transactions in futures and options on futures for  speculation.  The use of
futures and options on futures by Socially  Responsive  Portfolio is not subject
to the Social Policy.

         International  Portfolio  may  purchase  and sell futures for bona fide
hedging  purposes,  as defined in regulations  of the CFTC, and for  non-hedging
purposes (i.e., in an effort to enhance income). The Portfolio may also purchase
and write put and call options on such futures  contracts  for bona fide hedging
and non-hedging purposes.

         For purposes of managing  cash flow,  each  Portfolio  may purchase and
sell stock index futures contracts, and may purchase and sell options thereon to
increase its exposure to the performance of a recognized  securities index, such
as the S&P 500 Index.

         Limited  Maturity  Bond and Balanced  Portfolios  may purchase and sell
interest rate and bond index  futures and may purchase and sell options  thereon
in an attempt to hedge  against  changes in  securities  prices  resulting  from
changes in prevailing  interest rates. The Portfolios engage in foreign currency
futures  and  options  transactions  in an attempt to hedge  against  changes in
prevailing currency exchange rates. Neither Portfolio engages in transactions in
futures or options thereon for speculation.

         Call  Options  on  Securities.  (All  Portfolios  except  Liquid  Asset
Portfolio). Socially Responsive, Mid-Cap Growth, Limited Maturity Bond, Balanced
and  International  Portfolios  may write  covered call options and may purchase
call options on securities.  Each of the other Portfolios may write covered call
options and may  purchase  call  options in related  closing  transactions.  The
purpose of writing call options is to hedge (i.e., to reduce,  at least in part,
the effect of price  fluctuations  of  securities  held by the  Portfolio on the
Portfolio's NAV) or to earn premium income.  Portfolio  securities on which call
options may be written and purchased by a are  purchased  solely on the basis of
investment considerations consistent with the Portfolio's investment objective.

         When a  Portfolio  writes  a call  option,  it is  obligated  to sell a
security to a purchaser at a specified price at any time until a certain date if
the purchaser decides to exercise the option.  The Portfolio  receives a premium
for writing the call option.  When writing call options,  each Portfolio  writes
only  "covered" call options on securities it owns. So long as the obligation of
the call option  continues,  the Portfolio  may be assigned an exercise  notice,
requiring it to deliver the underlying  security against payment of the exercise
price. The Portfolio may be obligated to deliver securities underlying an option
at less than the market price.

         The  writing  of covered  call  options  is a  conservative  investment
technique that is believed to involve  relatively little risk, but is capable of
enhancing a  Portfolio's  total  return.  When writing a covered call option,  a
Portfolio, 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.

         If a call option that a Portfolio has written expires unexercised,  the
Portfolio will realize a gain in the amount of the premium;  however,  that gain
may be offset by a decline in the market value of the underlying security during
the option period. If the call option is exercised, the Portfolio will realize a
gain or loss from the sale of the underlying security.

         When a  Portfolio  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.

         Policies and  Limitations.  (Limited  Maturity Bond and Balanced  (debt
securities portion)  Portfolios).  Each Portfolio may write covered call options
and may purchase call options on debt  securities in its portfolio or on foreign
currencies  in its  portfolio  for hedging  purposes.  Each  Portfolio may write
covered call options for the purpose of producing  income.  Each  Portfolio will
write a call option on a security  only if it holds that security or currency or
has the right to obtain the security or currency at no additional cost.

         Equity  Portfolios.  Each  Portfolio may write covered call options and
may purchase call options in related closing transactions. Each Portfolio writes
only "covered" call options on securities it owns (in contrast to the writing of
"naked" or uncovered call options, which the Portfolio will not do).

         A Portfolio would purchase a call option to offset a previously written
call option. Each of Socially Responsive,  Mid-Cap Growth, Limited Maturity Bond
and Balanced  Portfolios  also may purchase a call option to protect  against an
increase in the price of the securities it intends to purchase.  The use of call
options on  securities  by Socially  Responsive  Portfolio is not subject to the
Social Policy.  International Portfolio may purchase call options for hedging or
non-hedging purposes.

         Put  Options  on  Securities.  (Socially  Responsive,  Mid-Cap  Growth,
International,  Limited  Maturity Bond and Balanced  Portfolios).  Each of these
Portfolios may write and purchase put options on securities. The Portfolios will
receive a premium for writing a put option,  which  obligates  the  Portfolio to
acquire a security  at a certain  price at any time until a certain  date if the
purchaser  decides to exercise  the option.  The  Portfolio  may be obligated to
purchase the underlying security at more than its current value.

         When a  Portfolio  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.  The  Portfolio  would  purchase a put option in
order to protect  itself  against a decline in the market value of a security it
owns.

         Portfolio  securities on which put options may be written and purchased
by a Portfolio  are purchased  solely on the basis of investment  considerations
consistent with the Portfolio's investment objective. When writing a put option,
the Portfolio,  in return for the premium,  takes the risk that it must purchase
the  underlying  security at a price that may be higher than the current  market
price of the security.  If a put option that the  Portfolio has written  expires
unexercised, the Portfolio will realize a gain in the amount of the premium.

         Policies  and  Limitations.  Socially  Responsive,  Mid-Cap  Growth and
International  Portfolios generally write and purchase put options on securities
for hedging  purposes  (i.e.,  to reduce,  at least in part, the effect of price
fluctuations  of  securities  held by the  Portfolio  on the  Portfolio's  NAV).
However,  International  Portfolio  also  may use put  options  for  non-hedging
purposes.  The use of put options on securities by Socially Responsive Portfolio
is not subject to the Social Policy.

         Limited  Maturity  Bond and  Balanced  Portfolios  generally  write and
purchase put options on securities or on foreign currencies for hedging purposes
(i.e.,  to  reduce,  at least in  part,  the  effect  of price  fluctuations  of
securities held by the Portfolio on the Portfolio's NAV).

         General Information About Securities Options.  The exercise price of an
option  may be below,  equal to, or above  the  market  value of the  underlying
security at the time the option is written.  Options  normally  have  expiration
dates  between  three  and nine  months  from the date  written.  American-style
options  are   exercisable  at  any  time  prior  to  their   expiration   date.
International  Portfolio  also may purchase  European-style  options,  which are
exercisable  only  immediately  prior to their  expiration  date. The obligation
under any option written by a Portfolio terminates upon expiration of the option
or, at an earlier time, when the Portfolio 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 Portfolio  and is never  exercised or closed out, the
Portfolio will lose the entire amount of the premium paid.

         Options are traded both on U.S.  national  securities  exchanges and in
the over-the-counter  ("OTC") market.  International Portfolio also may purchase
and sell options that are traded on foreign exchanges.  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
Portfolio and a counter-party,  with no clearing organization  guarantee.  Thus,
when a Portfolio  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  transaction  with  the  dealer  to whom (or from  whom)  the  Portfolio
originally  sold (or purchased)  the option.  There can be no assurance that the
Portfolio  would  be able to  liquidate  an OTC  option  at any  time  prior  to
expiration.  Unless a Portfolio 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 until
different cover is substituted.  In the event of the counter-party's insolvency,
a Portfolio may be unable to liquidate its options  position and the  associated
cover.  NB  Management  monitors  the  creditworthiness  of dealers with which a
Portfolio may engage in OTC options transactions.

         The  premium  received  (or paid) by a  Portfolio  when it  writes  (or
purchases)  an option is the amount at which the option is  currently  traded on
the applicable market. 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  interest  rate  environment.  The premium  received by a Portfolio  for
writing an option is recorded as a liability  on the  Portfolio's  statement  of
assets and liabilities. This liability is adjusted daily to the option's current
market  value,  which is the  last  reported  sales  price  before  the time the
Portfolio's  NAV is  computed  on the day the option is being  valued or, in the
absence of any trades  thereof on that day,  the mean  between the bid and asked
prices as of that time.

         Closing  transactions  are  effected  in order to  realize a profit (or
minimize a loss) 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 the  Portfolio  to write
another call option on the underlying  security with a different  exercise price
or expiration date or both.  There is, of course,  no assurance that a Portfolio
will be able to effect closing  transactions at favorable prices. If a Portfolio
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 at market risk on the
security.

         A  Portfolio  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.  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 the  Portfolio;  however,  the  Portfolio  could be in a less
advantageous position than if it had not written the call option.

         A Portfolio  pays brokerage  commissions or spreads in connection  with
purchasing  or  writing  options,  including  those  used to close out  existing
positions.  From time to time, the Portfolio 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.

         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.

         Policies  and  Limitations.   Each  Portfolio  may  use  American-style
options.  International  Portfolio may also purchase  European-style options and
may purchase and sell options that are traded on foreign exchanges.

         The  assets  used as cover (or held in a  segregated  account)  for OTC
options  written  by a  Portfolio  will be  considered  illiquid  unless the OTC
options  are  sold to  qualified  dealers  who  agree  that  the  Portfolio  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 use of put and call options by Socially Responsive Portfolio is not
subject to the Social Policy.

         Put and  Call  Options  on  Securities  Indices.  (Equity  Portfolios).
International  Portfolio may purchase put and call options on securities indices
for the  purpose  of  hedging  against  the risk of price  movements  that would
adversely  affect the value of the  Portfolio's  securities  or  securities  the
Portfolio  intends to buy. The Portfolio may write  securities  index options to
close out positions in such options that it has purchased.

         For purposes of managing cash flow, each Equity  Portfolio may purchase
put and call options on securities indices to increase the Portfolio's  exposure
to the performance of a recognized securities index, such as the S&P 500 Index.

         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 (1) the difference between the exercise price of the
option and the value of the underlying securities index on the exercise date (2)
multiplied by a fixed "index  multiplier." A securities  index  fluctuates  with
changes in the market values of the securities included in the index. Options on
stock indices are currently  traded on the Chicago Board Options  Exchange,  the
New York Stock Exchange  ("NYSE"),  the American Stock Exchange,  and other U.S.
and foreign exchanges.

         The  effectiveness  of hedging through the purchase of securities index
options will depend upon the extent to which price  movements in the  securities
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  Portfolio  will  not  exactly  match  the  composition  of the
securities indices on which options are available.

         Securities  index  options have  characteristics  and risks  similar to
those of securities options, as discussed herein.

         Policies and Limitations.  International Portfolio may purchase put and
call options on securities  indices for the purpose of hedging.  All  securities
index  options  purchased  by the  Portfolio  will be  listed  and  traded on an
exchange.  The  Portfolio  currently  does not  expect to  invest a  substantial
portion of its assets in securities index options.

         For purposes of managing cash flow, each Equity  Portfolio may purchase
put and call options on securities indices to increase the Portfolio's  exposure
to the performance of a recognized  securities index, such as the S&P 500 Index.
All  securities  index  options  purchased by the  Portfolio  will be listed and
traded on an exchange.

         Foreign  Currency  Transactions.  (All  Portfolios  except Liquid Asset
Portfolio).  Each Portfolio may enter into contracts for the purchase or sale of
a specific  currency at a future date  (usually less than one year from the date
of the contract) at a fixed price ("forward contracts").  The Portfolio also may
engage in foreign currency exchange transactions on a spot (i.e., cash) basis at
the spot rate prevailing in the foreign currency exchange market.

         The Portfolios (other than International  Portfolio) enter into forward
contracts in an attempt to hedge against changes in prevailing currency exchange
rates.  The Portfolios do not engage in  transactions  in forward  contracts for
speculation;   they  view  investments  in  forward  contracts  as  a  means  of
establishing  more definitely the effective return on, or the purchase price of,
securities  denominated in foreign  currencies.  Forward  contract  transactions
include  forward  sales or  purchases of foreign  currencies  for the purpose of
protecting  the U.S.  dollar  value of  securities  held or to be  acquired by a
Portfolio or protecting the U.S. dollar  equivalent of dividends,  interest,  or
other payments on those securities.

         Forward  contracts are traded in the interbank  market directly between
dealers (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;  foreign  exchange  dealers  realize  a profit  based on the
difference  (the spread) between the prices at which they are buying and selling
various currencies.

         At the consummation of a forward contract to sell currency, a Portfolio
may either make delivery of the foreign  currency or terminate  its  contractual
obligation to deliver by purchasing  an  offsetting  contract.  If the Portfolio
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  Portfolio  into such
currency. If the Portfolio 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  dealer who is a party to the  original  forward
contract.

         NB  Management  believes  that  the  use of  foreign  currency  hedging
techniques,  including "proxy-hedges," can provide significant protection of NAV
in the event of a general rise in the U.S.  dollar against  foreign  currencies.
For example,  the return  available from securities  denominated in a particular
foreign  currency  would  diminish  if the  value of the U.S.  dollar  increased
against that currency. Such a decline could be partially or completely offset by
an  increase  in value of a hedge  involving  a  forward  contract  to sell that
foreign  currency  or a  proxy-hedge  involving  a  forward  contract  to sell a
different  foreign  currency whose behavior is expected to resemble the currency
in which the securities  being hedged are  denominated but which is available on
more advantageous terms.

         However,  a hedge or proxy-hedge  cannot protect against  exchange rate
risks  perfectly,  and, if NB  Management is incorrect in its judgment of future
exchange  rate  relationships,  a  Portfolio  could  be in a  less  advantageous
position  than if such a hedge had not been  established.  If a  Portfolio  uses
proxy-hedging,  it may  experience  losses on both the  currency in which it has
invested and the  currency  used for hedging if the two  currencies  do not vary
with the expected degree of correlation.  Using forward contracts to protect the
value of a Portfolio's  securities  against a decline in the value of a currency
does not  eliminate  fluctuations  in the prices of the  underlying  securities.
Because  forward  contracts  are not traded on an  exchange,  the assets used to
cover such contracts may be illiquid.  A Portfolio may experience  delays in the
settlement of its foreign currency transactions.

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

         Policies and  Limitations.  The  Portfolios  (other than  International
Portfolio)  may enter into forward  contracts for the purpose of hedging and not
for speculation.  The use of forward contracts by Socially Responsive  Portfolio
is not subject to the Social Policy.

         International Portfolio may enter into forward contracts for hedging or
non-hedging   purposes.   When  the  Portfolio   engages  in  foreign   currency
transactions 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 Portfolio to deliver an amount of foreign currency materially
in excess of the value of its portfolio  securities or other assets  denominated
in that  currency.  International  Portfolio  may also purchase and sell forward
contracts for non-hedging purposes when NB Management anticipates that a 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
Portfolio's investment portfolio.

         Options on Foreign  Currencies.  (All  Portfolios  except  Liquid Asset
Portfolio).  Each Portfolio may write and purchase  covered call and put options
on foreign currencies.  International Portfolio 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.

         Currency  options have  characteristics  and risks  similar to those of
securities options,  as discussed herein.  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.

         Policies  and  Limitations.  A  Portfolio  would use options on foreign
currencies  to protect  against  declines in the U.S.  dollar value of portfolio
securities or increases in the U.S.  dollar cost of securities to be acquired or
to protect the U.S. dollar equivalent of dividends,  interest, or other payments
on those securities.  In addition,  International Portfolio may purchase put and
call options on foreign  currencies for non-hedging  purposes when NB Management
anticipates  that a  currency  will  appreciate  or  depreciate  in  value,  but
securities  denominated  in that currency do not present  attractive  investment
opportunities  and are not  included  in the  Portfolio.  The use of  options on
currencies by Socially Responsive Portfolio is not subject to the Social Policy.

         Regulatory Limitations on Using Financial Instruments.  To the extent a
Portfolio  sells or purchases  futures  contracts or writes  options  thereon or
options on foreign  currencies  that are traded on an exchange  regulated by the
CFTC other than for bona fide  hedging  purposes  (as defined by the CFTC),  the
aggregate  initial margin and premiums on those positions  (excluding the amount
by which options are  "in-the-money")  may not exceed 5% of the  Portfolio's net
assets.

         Cover  for  Financial  Instruments.  Securities  held  in a  segregated
account cannot be sold while the futures,  options,  or forward strategy covered
by those securities is outstanding, unless they are replaced with other suitable
assets. As a result,  segregation of a large percentage of a Portfolio's  assets
could impede  portfolio  management or the  Portfolio's  ability to meet current
obligations.  A  Portfolio  may be unable to  promptly  dispose of assets  which
cover,  or are  segregated  with respect to, an illiquid  futures,  options,  or
forward position; this inability may result in a loss to the Portfolio.

         Policies  and   Limitations.   Each  Portfolio  will  comply  with  SEC
guidelines regarding "cover" for Financial Instruments and, if the guidelines so
require,  set aside in a segregated  account with its custodian  the  prescribed
amount of cash or appropriate liquid securities.

         General  Risks of  Financial  Instruments.  The primary  risks in using
Financial  Instruments are: (1) imperfect  correlation or no correlation between
changes in market value of the  securities or currencies  held or to be acquired
by a Portfolio and changes in the prices of Financial Instruments;  (2) possible
lack of a liquid  secondary  market for Financial  Instruments and the resulting
inability to close out Financial Instruments when desired; (3) the fact that the
skills needed to use Financial  Instruments  are different  from those needed to
select a Portfolio's  securities;  (4) the fact that,  although use of Financial
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 a Portfolio  to  purchase  or sell a portfolio  security at a time that would
otherwise be favorable  for it to do so, or the possible need for a Portfolio to
sell a portfolio security at a disadvantageous time, due to its need to maintain
cover  or to  segregate  securities  in  connection  with  its use of  Financial
Instruments.  There can be no  assurance  that a  Portfolio's  use of  Financial
Instruments will be successful.

         Each  Portfolio's  use of Financial  Instruments  may be limited by the
provisions of the Internal Revenue Code of 1986, as amended ("Code"), with which
it must comply if it is to continue to qualify as a regulated investment company
("RIC").  See "Additional  Tax  Information."  Financial  Instruments may not be
available  with  respect  to some  currencies,  especially  those  of  so-called
emerging market countries.

         Policies and Limitations.  NB Management  intends to reduce the risk of
imperfect  correlation by investing only in Financial Instruments whose behavior
is expected to resemble or offset that of a Portfolio's underlying securities or
currency.  NB  Management  intends to reduce the risk that a  Portfolio  will be
unable to close out Financial  Instruments  by entering  into such  transactions
only if NB  Management  believes  there will be an active  and liquid  secondary
market.

         Indexed Securities.  (Limited Maturity Bond, International and Balanced
Portfolios).  These Portfolios may invest in securities whose value is 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 values at maturity or interest
rates rise or fall according to the change in one or more  specified  underlying
instruments.  The value of indexed  securities  may  increase or decrease if the
underlying  instrument  appreciates,  and they 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.

         Inflation-Indexed  Securities.  (Limited  Maturity  Bond  and  Balanced
Portfolios).  The  Portfolios  may  invest  in U.S.  Treasury  securities  whose
principal  value is adjusted  daily in  accordance  with changes to the Consumer
Price Index. Such securities are backed by the full faith and credit of the U.S.
Government.  Interest  is  calculated  on  the  basis  of the  current  adjusted
principal value. The principal value of inflation-indexed securities declines in
periods of  deflation,  but  holders at  maturity  receive no less than par.  If
inflation  is lower  than  expected  during  the  period a  Portfolio  holds the
security, the Portfolio may earn less on it than on a conventional bond.

         Because the coupon rate on  inflation-indexed  securities is lower than
fixed-rate U.S. Treasury securities, the Consumer Price Index would have to rise
at least to the amount of the  difference  between  the coupon rate of the fixed
rate  U.S.  Treasury  issues  and  the  coupon  rate  of  the  inflation-indexed
securities,  assuming all other factors are equal,  in order for such securities
to   match   the   performance   of   the   fixed-rate   Treasury    securities.
Inflation-indexed  securities are expected to react  primarily to changes in the
"real"  interest  rate (i.e.,  the  nominal  (or  stated)  rate less the rate of
inflation), while a typical bond reacts to changes in the nominal interest rate.
Accordingly,  inflation-indexed  securities have  characteristics  of fixed-rate
Treasuries  having a shorter  duration.  Changes in market  interest  rates from
causes  other  than   inflation   will  likely   affect  the  market  prices  of
inflation-indexed securities in the same manner as conventional bonds.

         Any  increase in  principal  value is taxable in the year the  increase
occurs,  even though holders do not receive cash representing the increase until
the security matures.  Because each Portfolio must distribute  substantially all
of its income to its  shareholders to avoid payment of federal income and excise
taxes,  a Portfolio may have to dispose of other  investments to obtain the cash
necessary  to  distribute  the  accrued  taxable  income  on   inflation-indexed
securities.

         Short Sales.  (International  Portfolio).  The Portfolio may attempt to
limit exposure to a possible decline in the market value of portfolio securities
through short sales of securities that NB Management believes possess volatility
characteristics  similar to those being hedged. The Portfolio also may use short
sales in an attempt to  realize  gain.  To effect a short  sale,  the  Portfolio
borrows a security  from a brokerage  firm to make  delivery  to the buyer.  The
Portfolio  then is obliged to replace the borrowed  security by purchasing it at
the market price at the time of replacement. Until the security is replaced, the
Portfolio is required to pay the lender any dividends and may be required to pay
a premium or interest.

         The  Portfolio  will realize a gain if the  security  declines in price
between the date of the short sale and the date on which the Portfolio  replaces
the  borrowed  security.  The  Portfolio  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 Portfolio is required to pay in  connection  with the short sale. A
short  position  may be  adversely  affected by  imperfect  correlation  between
movements in the price of the  securities  sold short and the  securities  being
hedged.

         The Portfolio  also may make short sales  against-the-box,  in which it
sells  securities  short  only if it owns or has the  right  to  obtain  without
payment  of  additional  consideration  an  equal  amount  of the  same  type of
securities sold.

         The effect of short  selling on the  Portfolio is similar to the effect
of leverage.  Short selling may amplify  changes in the  Portfolio's  NAV. Short
selling may also produce higher than normal portfolio turnover, which may result
in increased transaction costs to the Portfolio.

         Policies and Limitations. Under applicable guidelines of the SEC staff,
if  the   Portfolio   engages  in  a  short  sale   (other  than  a  short  sale
against-the-box),  it must put in a segregated  account (not with the broker) an
amount of cash or appropriate  liquid 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 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  Portfolio  replaces  the  borrowed
security, it must daily maintain the segregated account at such a level that (1)
the  amount  deposited  in it plus  the  amount  deposited  with the  broker  as
collateral equals the current market value of the securities sold short, and (2)
the  amount  deposited  in it plus  the  amount  deposited  with the  broker  as
collateral is not less than the market value of the  securities at the time they
were sold short.

         Asset-Backed  Securities.  (Liquid  Asset,  Limited  Maturity  Bond and
Balanced  Portfolios).  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.  Credit enhancements,  such as various
forms of cash collateral  accounts or letters of credit, may support payments of
principal and interest on asset-backed securities. 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,  which may be affected  adversely  by general  downturns  in the economy.
Asset-backed  securities  are subject to the same risk of  prepayment  described
with  respect  to  mortgage-backed   securities.   The  risk  that  recovery  on
repossessed  collateral might be unavailable or inadequate to support  payments,
however,  is  greater  for  asset-backed  securities  than  for  mortgage-backed
securities.

         Certificates   for  Automobile   Receivablessm   ("CARSsm")   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  those  contracts.  Payment of principal  and interest on the
underlying  contracts 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 CARSsm if the trust  does not  realize  the full
amounts due on underlying  installment  sales contracts because of unanticipated
legal or administrative costs of enforcing the contracts;  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  their  maturity  or  duration,  most  such
securities provide for a fixed period during which only interest payments on the
underlying  Accounts  are  passed  through  to the  security  holder;  principal
payments  received on the Accounts  are used to fund the transfer of  additional
credit card charges made on the  Accounts to the pool of assets  supporting  the
securities.  Usually,  the initial  fixed  period may be  shortened if specified
events occur which signal a potential deterioration in the quality of the assets
backing the  security,  such as the  imposition of a cap on interest  rates.  An
issuer's  ability  to  extend  the life of an issue of  credit  card  receivable
securities thus depends on the continued  generation of principal amounts in the
underlying  Accounts  and  the  non-occurrence  of  the  specified  events.  The
non-deductibility  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, thereby 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 those  laws 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 the  collateral  for most other
asset-backed securities, Accounts are unsecured obligations of the cardholder.

         Limited Maturity Bond and Balanced  Portfolios each may invest in trust
preferred securities, which are a type of asset-backed security. Trust preferred
securities  represent interests in a trust formed by a parent company to finance
its  operations.  The trust sells  preferred  shares and invests the proceeds in
debt  securities of the parent.  This debt may be  subordinated  and  unsecured.
Dividend payments on the trust preferred  securities match the interest payments
on the debt securities; if no interest is paid on the debt securities, the trust
will not make  current  payments on its  preferred  securities.  Unlike  typical
asset-backed  securities,  which have many  underlying  payors  and are  usually
overcollateralized,  trust preferred  securities have only one underlying  payor
and are not overcollateralized.  Issuers of trust preferred securities and their
parents currently enjoy favorable tax treatment.  If the tax characterization of
trust  preferred  securities  were to  change,  they  could be  redeemed  by the
issuers, which could result in a loss to a Portfolio.

         Convertible Securities.  (Equity Portfolios). Each Portfolio 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.  Convertible
securities generally have features of both common stocks and debt securities.  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.

         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.  Convertible   securities  are  typically  issued  by  smaller  capitalized
companies whose stock prices may be volatile.  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.
Convertible  securities  generally  have features of both common stocks and debt
securities. 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 Portfolio is called for redemption, the Portfolio
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 a Portfolio's  ability to achieve its investment
objective.

        Policies and Limitations. Socially Responsive Portfolio may invest up to
20% of its net assets in convertible  securities.  The Portfolio does not intend
to  purchase  any  convertible   securities  that  are  not  investment   grade.
Convertible debt securities are subject to each Portfolio's  investment policies
and limitations concerning debt securities.

         Preferred  Stock.  (Equity  Portfolios).  The  Portfolios may invest in
preferred  stock.  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.

         Zero Coupon  (Partners,  Socially  Responsive,  Limited  Maturity Bond,
Balanced,  and Liquid Asset  Portfolios)  and Step Coupon  Securities.  (Limited
Maturity Bond and Balanced Portfolio).  The Portfolios may invest in zero coupon
securities and Limited Maturity Bond and Balanced  Portfolios may invest in step
coupon  securities,  both of which are debt  obligations that do not entitle the
holder to any periodic  payment of interest  prior to maturity or that specify a
future date when the securities begin paying current  interest.  Zero coupon and
step coupon  securities  are issued and traded at a  significant  discount  from
their face amount or par value.  The 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. They are redeemed
at face value when they mature.

         The discount on zero coupon and step coupon securities ("original issue
discount"  or "OID")  must be taken into income  ratably by each such  Portfolio
prior to the  receipt  of any  actual  payments.  Because  each  Portfolio  must
distribute to its shareholders substantially all of its net income each year for
income tax  purposes,  a Portfolio  may have to dispose of portfolio  securities
under  disadvantageous  circumstances  to generate  cash,  or may be required to
borrow, to satisfy its distribution requirements.

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

         Municipal Obligations.  (Income Portfolios).  Municipal obligations are
securities  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
municipal   obligations  is  generally  exempt  from  federal  income  tax.  The
tax-exempt  status of any issue of municipal  obligations  is  determined on the
basis of an opinion of the issuer's bond counsel at the time the obligations are
issued.

         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  Portfolio  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 a  Portfolio's  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 adversely
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 restructuring of the federal income tax system.  These  developments
could  reduce  the  value of all  municipal  securities,  or the  securities  of
particular issuers.

         Policies and Limitations. Limited Maturity Bond Portfolio may invest up
to 5% of its net assets in municipal  obligations.  Liquid Asset  Portfolio  may
invest in municipal obligations that otherwise meet its criteria for quality and
maturity.

         U.S.   Government  and  Agency  Securities.   (All  Portfolios).   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, or by instrumentalities of the
U.S. Government,  such as the Government National Mortgage Association ("GNMA"),
Fannie Mae (also known as the Federal National  Mortgage  Association),  Freddie
Mac (also known as the Federal  Home Loan  Mortgage  Corporation),  Student Loan
Marketing  Association  (commonly known as "Sallie Mae"),  and Tennessee  Valley
Authority.  Some U.S.  Government  Agency  Securities  are supported by the full
faith and credit of the United  States,  while  others may be  supported  by 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 Agency  Securities  include U.S.  Government  Agency  mortgage-backed
securities. (See "Mortgage-Backed Securities," below.) The market prices of U.S.
Government  Agency Securities are not guaranteed by the Government and generally
fluctuate inversely with changing interest rates.

         Policies and Limitations. Liquid Asset Portfolio may invest 25% or more
of its total assets in U.S. Government and Agency

         Securities.  The  Equity  Portfolios  normally  may invest up to 35% of
their total assets in debt  securities,  including  U.S.  Government  and Agency
Securities.

         Swap  Agreements.  (International  Portfolio).  The Portfolio may enter
into  swap  agreements  to  manage  or gain  exposure  to  particular  types  of
investments  (including  equity  securities  or indices of equity  securities in
which the Portfolio otherwise could not invest efficiently).  In an example of a
swap  agreement,  one party agrees to make regular  payments equal to a floating
rate on a specified  amount in exchange for payments equal to a fixed rate, or a
different floating rate, on the same amount for a specified period.

         Swap  agreements  may  involve  leverage  and may be  highly  volatile;
depending  on how they are  used,  they may have a  considerable  impact  on the
Portfolio's  performance.  The risks of swap  agreements  depend  upon the other
party's  creditworthiness  and  ability to perform,  as well as the  Portfolio's
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.

         Policies and  Limitations.  In accordance with SEC staff  requirements,
the Portfolio will segregate cash or appropriate  liquid securities in an amount
equal to its obligations under swap agreements;  when an agreement  provides for
netting of the payments by the two parties,  the Portfolio  will  segregate only
the amount of its net obligation, if any.

         Fixed Income Securities. (All Portfolios). The Income Portfolios invest
primarily  in  fixed  income  securities.  While  the  emphasis  of  the  Equity
Portfolios' investment programs is on common stocks and other equity securities,
the Portfolios may also invest in money market instruments,  U.S. Government and
Agency Securities, and other fixed income securities.  Each Portfolio may invest
in investment  grade corporate bonds and debentures.  Partners,  Mid-Cap Growth,
Limited Maturity Bond,  Balanced and International  Portfolio each may invest in
corporate debt securities rated below investment grade.

         "Investment  grade" debt securities are those receiving one of the four
highest ratings from Moody's Investors  Service,  Inc.  ("Moody's"),  Standard &
Poor's ("S&P"), or another nationally recognized statistical rating organization
("NRSRO") or, if unrated by any NRSRO,  deemed by NB Management to be comparable
to such rated securities ("Comparable Unrated Securities").  Securities rated by
Moody's  in its fourth  highest  rating  category  (Baa) or  Comparable  Unrated
Securities may be deemed to have speculative characteristics.

         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.  Although the Portfolios may rely on the ratings of any NRSRO,
the Portfolios primarily refer to 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 its  obligations  ("credit
risk") and are subject to price  volatility due to such factors as interest rate
sensitivity, market perception of the creditworthiness of the issuer, and market
liquidity  ("market risk").  The value of the fixed income securities in which a
Portfolio  may invest is likely to decline  in times of rising  market  interest
rates.  Conversely,  when rates fall,  the value of a  Portfolio's  fixed income
investments  is likely to rise.  Foreign  debt  securities  are subject to risks
similar to those of other foreign  securities.  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.

         Lower Rated Debt Securities.  (Balanced, Limited Maturity Bond, Mid-Cap
Growth, Partners and International  Portfolios).  Lower-rated debt securities or
"junk  bonds" are those  rated below the fourth  highest  category by all NRSROs
that have rated them (including  those  securities  rated as low as D by S&P) or
unrated  securities of comparable  quality.  Securities  rated below  investment
grade  may be  considered  speculative.  Securities  rated  B are  judged  to be
predominantly  speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with their terms and obligations.  Lower rated
debt  securities  generally offer a higher current yield than that available for
investment  grade  issues  with  similar   maturities,   but  they  may  involve
significant  risk under adverse  conditions.  In particular,  adverse changes in
general  economic  conditions  and in the  industries  in which the  issuers are
engaged and changes in the financial condition of the issuers are more likely to
cause price  volatility  and weaken the capacity of the issuer to make principal
and interest  payments than is the case for  higher-grade  debt  securities.  In
addition,  a  Portfolio  that  invests  in  lower-quality  securities  may incur
additional  expenses to the extent  recovery is sought on defaulted  securities.
Because of the many risks  involved in investing in high-yield  securities,  the
success  of  such  investments  is  dependent  on  the  credit  analysis  of  NB
Management.

         During periods of economic  downturn or rising interest  rates,  highly
leveraged  issuers may experience  financial stress which could adversely affect
their  ability to make  payments of interest  and  principal  and  increase  the
possibility of default. In addition,  such issuers may not have more traditional
methods  of  financing  available  to them and may be  unable  to repay  debt at
maturity  by  refinancing.  The risk of loss due to default  by such  issuers is
significantly  greater  because such  securities  frequently  are  unsecured and
subordinated to the prior payment of senior indebtedness.

         The market for lower  rated debt  securities  has  expanded  rapidly in
recent years, and its growth generally paralleled a long economic expansion.  In
the past, the prices of many lower rated debt securities declined substantially,
reflecting an expectation  that many issuers of such securities might experience
financial  difficulties.  As a result, the yields on lower rated debt securities
rose dramatically.  However, such higher yields did not reflect the value of the
income stream that holders of such securities expected, but rather the risk that
holders of such securities could lose a substantial  portion of their value as a
result of the issuers'  financial  restructuring  or  defaults.  There can be no
assurance that such declines will not recur.

         The market for lower  rated debt  issues  generally  is thinner or less
active than that for higher  quality  securities,  which may limit a Portfolio's
ability  to sell such  securities  at fair value in  response  to changes in the
economy or financial  markets.  Judgment may play a greater role in pricing such
securities  than it does for  more  liquid  securities.  Adverse  publicity  and
investor  perceptions,  whether or not based on fundamental  analysis,  may also
decrease the values and liquidity of lower rated debt securities,  especially in
a thinly traded market.

         See  Appendix  A for  further  information  about the  ratings  of debt
securities assigned by S&P and Moody's.

         Policies and  Limitations.  Partners  Portfolio 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.  Limited Maturity
Bond and  Mid-Cap  Growth  Portfolios  may invest up to 10% of their net assets,
measured at the time of investment,  in debt securities  rated below  investment
grade,  but rated at least B with respect to Limited Maturity Bond Portfolio and
C with  respect to Mid-Cap  Growth  Portfolio by S&P or Moody's,  or  Comparable
Unrated  Securities.  Balanced  Portfolio  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 at least B by S&P or
Moody's, or Comparable Unrated Securities.

         International  Portfolio  may  invest  in  domestic  and  foreign  debt
securities  of any rating,  including  those rated  below  investment  grade and
Comparable Unrated Securities.

         Subsequent to its purchase by a Portfolio,  an issue of debt securities
may cease to be rated or its rating may be reduced, so that the securities would
no longer be eligible for purchase by that Portfolio.  In such a case,  Socially
Responsive  Portfolio  will engage in an orderly  disposition  of the downgraded
securities,  and Limited  Maturity Bond and Balanced (debt  securities  portion)
Portfolios will engage in an orderly disposition of the downgraded securities or
other securities to the extent necessary to ensure the Portfolio's holdings that
are considered by the Portfolio to be below investment grade will not exceed 10%
of its net assets.  Limited Maturity Bond and Balanced (debt securities portion)
Portfolios  may each  hold up to 5% of its net  assets  in  securities  that are
downgraded  after purchase to a rating below that permissible by the Portfolio's
investment policies. Each other Portfolio (except International  Portfolio) will
engage  in an  orderly  disposition  of  downgraded  securities  to  the  extent
necessary  to ensure that the  Portfolio's  holdings of  securities  rated below
investment grade and Comparable Unrated Securities will not exceed 5% of its net
assets  (15% in the case of  Partners  Portfolio  and 10% in the case of Mid-Cap
Growth  Portfolio).  NB  Management  will  make a  determination  as to  whether
International  Portfolio  should  dispose  of the  downgraded  securities.  With
respect to Liquid  Asset  Portfolio,  NB  Management  will  consider the need to
dispose of such  securities in  accordance  with the  requirements  of Rule 2a-7
under the 1940 Act.

         NB  Management  will  invest  in  lower-rated  securities  only when it
concludes that the anticipated return on such an investment to Partners, Mid-Cap
Growth or International  Portfolio  warrants exposure to the additional level of
risk.

Ratings of Fixed Income Securities

         As discussed  above,  the Portfolios may purchase  securities  rated by
S&P, Moody's,  or any other 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, duration,
coupon,  and rating may have different yields.  Although the Portfolios may rely
on the ratings of any NRSRO,  the Portfolio  mainly refer to ratings assigned by
S&P and  Moody's,  which are  described in Appendix A. Each  Portfolio  may also
invest in  unrated  securities  that are  deemed  comparable  in  quality  by NB
Management  to the rated  securities  in which  the  Portfolio  may  permissibly
invest.

         High-quality   debt  securities.   High-quality   debt  securities  are
securities  that have received a rating from at least one 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 NB Management to be of
comparable quality. If two or more NRSROs have rated a security, at least two of
them must rate it as high quality if the security is to be eligible for purchase
by Liquid Asset Portfolio.

         Investment Grade Debt Securities.  Investment grade debt securities are
securities  that have  received  a rating  from at least one NRSRO in one of the
four  highest  rating  categories  or,  if not  rated by any  NRSRO,  have  been
determined  by  NB  Management  to  be  of  comparable  quality.  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.

         Lower-Rated  Debt  Securities.  Lower-rated  debt  securities  or "junk
bonds" are those rated below the fourth highest category by all NRSROs that have
rated  them  (including  those  securities  rated as low as D by S&P) or unrated
securities of comparable quality. Securities rated below investment grade may be
considered  speculative.  Securities  rated  B are  judged  to be  predominantly
speculative  with respect to their capacity to pay interest and repay  principal
in  accordance  with the terms of the  obligations.  Although  these  securities
generally offer higher yields than investment grade debt securities with similar
maturities,  lower-quality  securities  involve  greater  risks,  including  the
possibility  of default or  bankruptcy  by the  issuer,  or the  securities  may
already be in default.  See the additional risks described above for lower-rated
securities.

         Subsequent to its purchase by a Portfolio,  an issue of debt securities
may cease to be rated or its rating may be reduced, so that the securities would
no longer be eligible for purchase by that  Portfolio.  The policy on downgraded
securities is discussed above under "Lower Rated Debt Securities."

Duration and Maturity

         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.  For Limited  Maturity Bond and Balanced  (debt  securities  portion)
Portfolios,  NB Management  utilizes  duration as a tool in portfolio  selection
instead of the more  traditional  measure known as "term to maturity."  "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 Portfolio'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 of the 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 and expected
prepayment  rates are critical in  determining  the  securities'  interest  rate
exposure. In these and other similar situations, NB 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.

         Liquid  Asset  Portfolio  is  required  to  maintain a  dollar-weighted
average portfolio  maturity of no more than 90 days and invest in a portfolio of
debt instruments with remaining maturities of 397 days or less. Limited Maturity
Bond and Balanced (debt securities portion) Portfolios'  dollar-weighted average
duration  will not exceed  four years,  although  each  Portfolio  may invest in
individual securities of any duration; the Portfolios'  dollar-weighted  average
maturity may range up to six years.

Risks of Equity Securities

         The Equity  Portfolios  may invest in  securities  that include  common
stocks, preferred stocks, convertible securities and warrants. Common stocks and
preferred  stocks  represent  shares of  ownership in a  corporation.  Preferred
stocks  usually have  specific  dividends and rank after bonds and before common
stock in claims on assets of the corporation  should it be dissolved.  Increases
and decreases in earnings are usually reflected in a corporation's  stock price.
Convertible  securities are debt or preferred equity securities convertible into
common stock. Usually, convertible securities pay dividends or interest at rates
higher  than  common  stock,  but  lower  than  other  securities.   Convertible
securities   usually   participate  to  some  extent  in  the   appreciation  or
depreciation of the underlying stock into which they are  convertible.  Warrants
are  options  to buy a stated  number of shares of common  stock at a  specified
price anytime during the life of the warrants.

         To the  extent a  Portfolio  invests in such  securities,  the value of
securities  held by the  Portfolio  will be  affected  by  changes  in the stock
markets,  which may be the result of  domestic  or  international  political  or
economic news,  changes in interest  rates or changing  investor  sentiment.  At
times,   the  stock  markets  can  be  volatile  and  stock  prices  can  change
substantially.  The equity securities of smaller companies are more sensitive to
these changes than those of larger  companies.  This market risk will affect the
Portfolio's  NAV per share,  which will fluctuate as the value of the securities
held by the Portfolio  changes.  Not all stock prices change uniformly or at the
same time and not all stock markets move in the same direction at the same time.
Other factors affect a particular stock's prices,  such as poor earnings reports
by an issuer,  loss of major customers,  major litigation  against an issuer, or
changes  in  governmental  regulations  affecting  an  industry.   Adverse  news
affecting one company can sometimes depress the stock prices of all companies in
the same industry. Not all factors can be predicted.

      Other  Investment  Companies.  International  Portfolio  may invest in the
shares of other investment companies.  Such investment may be the most practical
or only manner in which the Portfolio can participate in certain foreign markets
because of the expenses  involved or because  other  vehicles  for  investing in
those  countries may not be available at the time the Portfolio is ready to make
an  investment.  Each  Equity  Portfolio  at times  may  invest  in  instruments
structured as  investment  companies to gain  exposure to the  performance  of a
recognized  securities index,  such as the S&P 500 Index or another  appropriate
index.  Limited Maturity Bond and Balanced  Portfolios,  for temporary defensive
purposes,  may each invest up to 10% of its total  assets in the  securities  of
money market funds.

         As a shareholder in an investment  company,  a Portfolio would bear its
pro rata share of that  investment  company's  expenses.  At the same time,  the
Portfolio will continue to pay its own management fees and expenses with respect
to  its  portfolio  investments,   including  the  shares  of  other  investment
companies.  Investment  in other funds may  involve  the payment of  substantial
premiums above the value of such issuer's portfolio  securities.  The Portfolios
do not intend to invest in such funds unless,  in the judgment of NB Management,
the potential  benefits of such investment justify the payment of any applicable
premium or sales charge.

         Policies  and  Limitations.   Each   Portfolio's   investment  in  such
securities is limited to (i) 3% of the total voting stock of any one  investment
company,  (ii)  5% of the  Portfolio's  total  assets  with  respect  to any one
investment  company  and  (iii)  10%  of the  Portfolio's  total  assets  in the
aggregate.

         Preferred  Stock.  (Equity  Portfolios).  Each  Portfolio may invest in
preferred  stock.  Unlike  interest  payments on debt  securities,  dividends on
preferred stock are generally payable at the discretion of the issuer's board of
directors.  Preferred  shareholders may have certain rights if dividends are not
paid but generally have no legal recourse  against the issuer.  Shareholders may
suffer a loss of value if dividends are not paid. The market prices of preferred
stocks are generally more sensitive to changes in the issuer's  creditworthiness
than are the prices of debt securities.

Socially Responsive Portfolio - Description of Social Policy

         Background Information on Socially Responsive Investing

         In an era when many people are concerned about the relationship between
business and society,  socially responsive  investing ("SRI") is a mechanism for
assuring  that  investors'  social  values  are  reflected  in their  investment
decisions. As such, SRI is a direct descendent of the successful effort begun in
the early 1970's to encourage companies to divest their South African operations
and subscribe to the Sullivan Principles. Today, a growing number of individuals
and institutions are applying similar strategies to a broad range of problems.

         Although there are many strategies available to the socially responsive
investor,  including proxy activism,  below-market loans to community  projects,
and venture  capital,  the SRI strategies  used by the Portfolio  generally fall
into two categories:

         Avoidance  Investing.  Most socially responsive investors seek to avoid
holding  securities of companies whose products or policies are seen as being at
odds with the social good. The most common exclusions historically have involved
tobacco companies and weapons manufacturers.

         Leadership  Investing.  A growing number of investors actively look for
companies with  progressive  programs that are exemplary or companies which make
it their business to try to solve some of the problems of today's society.

         The  marriage  of  social  and  financial  objectives  would  not  have
surprised Adam Smith,  who was,  first and foremost,  a moral  philosopher.  The
Wealth of  Nations is firmly  rooted in the  Enlightenment  conviction  that the
purpose of capital is the social good and the related  belief that idle  capital
is both wasteful and unethical. But, what very likely would have surprised Smith
is the sheer  complexity of the social issues we face today and the diversity of
our  attitudes  toward the social  good.  War and peace,  race and  gender,  the
distribution of wealth,  and the conservation of natural resources -- the social
agenda is long and  compelling.  It is also  something  about  which  reasonable
people differ. What should society's  priorities be? What can and should be done
about  them?  And  what is the  role  of  business  in  addressing  them?  Since
corporations  are on the front lines of so many key issues in today's  world,  a
growing  number of investors feel that a  corporation's  role cannot be ignored.
This is true of some of the  most  important  issues  of the day  such as  equal
opportunity and the environment.

         The Socially Responsive Database

         Neuberger   Berman,   LLC   ("Neuberger   Berman"),   the   Portfolio's
sub-adviser,  maintains a database of information about the social impact of the
companies it follows.  NB Management uses the database to evaluate social issues
after it deems a stock acceptable from a financial standpoint for acquisition by
the Portfolio.  The aim of the database is to be as  comprehensive  as possible,
given that much of the information  concerning  corporate  responsibility  comes
from subjective  sources.  Information for the database is gathered by Neuberger
Berman in many  categories  and then  analyzed by NB Management in the following
six categories of corporate responsibility:

         Workplace  Diversity and Employment.  NB Management looks for companies
that show leadership in areas such as employee  training and promotion  policies
and benefits, such as flextime,  generous profit sharing, and parental leave. NB
Management  looks for active  programs to promote women and minorities and takes
into account their representation among the officers of an issuer and members of
its board of directors.  As a basis for exclusion, NB Management looks for Equal
Employment  Opportunity Act infractions and  Occupational  Safety and Health Act
violations; examines each case in terms of severity, frequency, and time elapsed
since  the  incident;  and  considers  actions  taken by the  company  since the
violation.  NB Management also monitors companies' progress and attitudes toward
these issues.

         Environment.  A company's impact on the environment  depends largely on
the industry. Therefore, NB Management examines a company's environmental record
vis-a-vis  those of its peers in the  industry.  All  companies  operating in an
industry  with  inherently  high  environmental  risks  are  likely  to have had
problems in such areas as toxic chemical emissions, federal and state fines, and
Superfund sites. For these companies,  NB Management  examines their problems in
terms of severity,  frequency, and elapsed time. NB Management then balances the
record against whatever leadership the company may have demonstrated in terms of
environmental  policies,  procedures,  and practices.  NB Management  defines an
environmental  leadership company as one that puts into place strong affirmative
programs to minimize  emissions,  promote  safety,  reduce  waste at the source,
insure energy conservation, protect natural resources, and incorporate recycling
into its processes and products.  NB  Management  looks for the  commitment  and
active  involvement  of senior  management  in all these  areas.  Several  major
manufacturers which still produce substantial amounts of pollution are among the
leaders  in  developing  outstanding  waste  source  reduction  and  remediation
programs.

         Product. NB Management considers company announcements,  press reports,
and public  interest  publications  relating  to the  health,  safety,  quality,
labeling,  advertising,  and promotion of both consumer and industrial products.
NB Management  takes note of companies  with a strong  commitment to quality and
with marketing practices which are ethical and consumer-friendly.  NB Management
pays  particular  attention to  companies  whose  products and services  promote
progressive solutions to social problems.

         Public Health. NB Management measures the participation of companies in
such industries and markets as alcohol,  tobacco, gambling and nuclear power. NB
Management  also  considers  the impact of  products  and  marketing  activities
related  to those  products  on  nutritional  and other  health  concerns,  both
domestically and in foreign markets.

         Weapons.  NB  Management  keeps track of domestic  military  sales and,
whenever  possible,  foreign  military  sales and  categorizes  them as  nuclear
weapons related,  other weapons related, and non-weapon military supplies,  such
as  micro-chip  manufacturers  and  companies  that make  uniforms  for military
personnel.

         Corporate  Citizenship.  NB  Management  gathers  information  about  a
company's  participation  in community  affairs,  its  policies  with respect to
charitable  contributions,  and  its  support  of  education  and the  arts.  NB
Management  looks for  companies  with a focus,  dealing with issues not just by
making financial contributions, but also by asking the questions: What can we do
to help? What do we have to offer? Volunteerism, high-school mentoring programs,
scholarships and grants, and in-kind donations to specific groups are just a few
ways that companies have responded to these questions.

         Implementation of Social Policy

         Companies   deemed   acceptable  by  NB  Management  from  a  financial
standpoint are analyzed using  Neuberger  Berman's  database.  The companies are
then evaluated by the portfolio manager to determine if the companies' policies,
practices,  products,  and services  withstand  scrutiny in the following  major
areas of concern:  the  environment  and  workplace  diversity  and  employment.
Companies are then further  evaluated to determine  their track record in issues
and areas of concern such as public  health,  weapons,  product,  and  corporate
citizenship.

         The issues and areas of concern  that are tracked  lend  themselves  to
objective analysis in varying degrees. Few, however, can be resolved entirely on
the basis of scientifically  demonstrable facts.  Moreover, a substantial amount
of  important  information  comes  from  sources  that  do  not  purport  to  be
disinterested.  Thus,  the  quality and  usefulness  of the  information  in the
database depend on Neuberger  Berman's  ability to tap a wide variety of sources
and on the  experience and judgment of the people at NB Management who interpret
the information.

         In applying the  information in the database to stock selection for the
Portfolio,  NB Management  considers several factors. NB Management examines the
severity and frequency of various infractions, as well as the time elapsed since
their  occurrence.  NB  Management  also takes into account any remedial  action
which has been taken by the company relating to these infractions. NB Management
notes  any  quality  innovations  made by the  company  in its  effort to create
positive change and looks at the company's overall approach to social issues.

                             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
yield and total  return of each  Portfolio  will vary,  and an  investment  in a
Portfolio,  when redeemed,  may be worth more or less than the original purchase
price.  Performance  information does not reflect insurance product or qualified
plan expenses.

Yield Calculations

         The Liquid  Asset  Portfolio  may  advertise  its  "current  yield" and
"effective  yield." The  Portfolio's  current yield is based on the return for a
recent 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)365/7] - 1

         For the seven  calendar days ended December 31, 1999, the current yield
of the Liquid Asset  Portfolio  was 4.77%.  For the same period,  the  effective
yield was 4.88%.

         Limited  Maturity  Bond  Portfolio.  The  Portfolio  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 for the
30-day period ended December 31, 1999 was 6.22%.

Total Return Computations.  (All Portfolios except Liquid Asset Portfolio).

         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)n = ERV

         Average  annual total return  smoothes out  year-to-year  variations in
performance 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,  1999,  were  +50.40%,
+26.37%, and +15.61%, 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, 1999, were +1.48%, +5.52%, and +5.86%, 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,  five,  and ten-year  periods  ended  December 31, 1999,  were +33.56%,
+18.81%, and +12.65%, 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 and five-year  periods  ended  December 31, 1999 and for the period
from March 22, 1994  (commencement of operations)  through December 31, 1999 was
+7.37%, +21.03%, and +17.47% respectively.

         The average  annual total return for the Mid-Cap  Growth  Portfolio for
the one year  period  ended  December  31, 1999 and the period  since  inception
(November  3,  1997)  through   December  31,  1999  was  +53.89%  and  +52.97%,
respectively.

         The average annual total return for the Guardian  Portfolio for the one
year period ended December 31, 1999 and the period since inception  (November 3,
1997) through December 31, 1999 was +14.93 and +23.93% respectively.

         The average annual total return for the Socially  Responsive  Portfolio
for the period from February 18, 1999 (inception date) through December 31, 1999
was +15.40%.

         NB  Management  may waive a portion of its fee or reimburse  certain of
the Portfolios and  predecessors  of the Portfolios for certain  expenses during
the periods  shown,  which has the effect of  increasing  total  return.  Actual
reimbursements  and waivers are described in the  Prospectus  and in "Investment
Management and Administrative Services" below.

         Average  annual total  returns  quoted for the  Portfolios  include the
effect of deducting a Portfolio's expenses, but do not include insurance-related
charges and other 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 (except with respect to the Balanced Portfolio,
which may also be purchased by Qualified  Plans) 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

         From time to time a Portfolio's performance may be compared with:

                  (1) data  (that  may be  expressed  as  rankings  or  ratings)
         published   by   independent   services  or   publications   (including
         newspapers,  newsletters,  and financial  periodicals) that monitor the
         performance of mutual funds, such as Lipper Analytical  Services,  Inc.
         ("Lipper"),   C.D.A.   Investment   Technologies,   Inc.,  Wiesenberger

         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 $35  million to $6.1
         billion,  with an  average  of  $572  million.  The  S&P  400  measures
         mid-sized  companies  with an  average  market  capitalization  of $2.1
         billion. The EAFE(R) Index is an unmanaged index of common stock prices
         of more than 1,000 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.  Each  Portfolio  may
         invest in different  types of securities from those included in some of
         the above indices.

         The Limited Maturity Bond Portfolio's  performance may also be compared
with  the  Merrill  Lynch  1-3  year  Treasury  Index  and the  Lehman  Brothers
Intermediate  Government/Corporate  Bond Index,  as well as the  performance  of
Treasury Securities, corporate bonds, and the Lipper Short Investment Grade Debt
Funds category.

         The Socially Responsive Portfolio's performance may also be compared to
various socially responsive  indices.  These include The Domini Social Index and
the indices developed by the quantitative  department of Prudential  Securities,
such as that  department's  Large and  Mid-Cap  portfolio  indices  for  various
breakdowns ("Sin" Stock Free, Cigarette-Stock Free, S&P Composite, etc.).

         Evaluations of a Portfolio's  performance,  its yield/total  return and
comparisons  may be used  in  advertisements  and in  information  furnished  to
present  and  prospective  shareholders  (collectively,  "Advertisements").  The
Portfolios  may also be  compared to  individual  asset  classes  such as common
stocks,  small-cap stocks, or Treasury bonds,  based on information  supplied by
Ibbotson and Sinquefield.

         Each  Portfolio  may invest  some of its assets in  different  types of
securities  than  those  included  in the index  used as a  comparison  with the
Portfolio's  historical  performance.  A  Portfolio  may  also  compare  certain
indices,  which represent different segments of the securities markets,  for the
purpose of comparing the historical  returns and volatility of those  particular
market  segments.  Measures of  volatility  show the range of  historical  price
fluctuations.  Standard deviation may be used as a measure of volatility.  There
are other measures of volatility, which may yield different results.

         In  addition,  the Income  Portfolios'  performance  may be compared at
times  with that of  various  bank  instruments  (including  bank  money  market
accounts and CDs of varying  maturities) as reported in publications such as The
Bank Rate Monitor.  Any such  comparisons may be useful to investors who wish to
compare a Portfolio's  past performance with that of certain of its competitors.
Of course,  past  performance  is not a guarantee of future  results.  Unlike an
investment  in a  Portfolio,  bank CDs pay a fixed rate of interest for a stated
period of time and are insured up to $100,000.

         Other Performance  Information.  From time to time, information about a
Portfolio's  portfolio  allocation  and holdings as of a particular  date may be
included   in   Advertisements.   This   information   may   include   portfolio
diversification by asset type.

605 Third Avenue,  New York, New York 10158. (2) Except as otherwise  indicated,
each individual has held the position shown for at least the last five years.

         * Indicates a Trustee who is an "interested person" of the Trust within
the meaning of the 1940 Act. Mr.  Zicklin is an  interested  person by virtue of
the fact that he is a  Director  of NB  Management  and a Managing  Director  of
Neuberger Berman.

         The Trust's Trust Instrument provides that the Trust will indemnify the
Trustees and officers against  liabilities and expenses  reasonably  incurred in
connection  with  litigation  in which  they may be  involved  because  of their
offices with the Trust unless it is adjudicated  that they engaged in bad faith,
willful  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  willful  misfeasance,  bad  faith,  gross  negligence,  or  reckless
disregard of their duties.  As discussed above under  "Investment  Information",
effective  May  1,  2000,   each  Portfolio   redeemed  its  investment  in  its
corresponding  series of Advisers  Managers  Trust  in-kind at current net asset
value,  subject to the  liabilities of Advisers  Managers  Trust,  including the
indemnification  obligations to the trustees of Advisers Managers Trust, who are
the same  individuals  that serve on the Board of Trustees  of the Trust.  These
indemnification  obligations are substantially  the same as the  indemnification
obligation of the Trust to its Trustees.

         Trustees  who are not managing  directors,  officers or employees of NB
Management,  Neuberger Berman and/or the participating life insurance  companies
or any of their  affiliates are paid trustees' fees. For the year ended December
31, 1999, a total of $104,792 in fees was paid to the Trustees as a group by the
Trust and a total of  $107,192  in fees was paid to the  Trustees  as a group by
Advisers Managers Trust. The following table shows 1999 compensation by Trustee.

               CONTROL PERSONS AND PRINCIPAL HOLDERS OF SECURITIES

         Shares of the  Portfolios  are issued and redeemed in  connection  with
investments  in and  payments  under  certain  variable  annuity  contracts  and

through separate  accounts of life insurance  companies (the "Life  Companies").
Shares of the Balanced  Portfolio are also offered  directly to Qualified Plans.

           INVESTMENT MANAGEMENT, ADVISORY AND ADMINISTRATION SERVICES

         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  $54.4  billion as of December 31, 1999.  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-1970s.  Most money managers that come
to the Neuberger Berman  organization have at least fifteen years of experience.
Neuberger Berman and NB Management employ experienced professionals that work in
a competitive environment.

         NB Management serves as each Portfolio's investment manager pursuant to
a Management  Agreement  ("Management  Agreement") dated as of May 1, 2000, that
was approved by the Trustees on February 29, 2000.

         From May 1, 1995 through April 30, 2000,  NB  Management  served as the
investment manager of the corresponding master series of Advisers Managers Trust
in which each Portfolio invested its net investable assets.

         The Management  Agreement provides in substance that NB Management will
make and implement investment decisions for the Portfolios in its discretion and
will continuously develop an investment program for each Portfolio's assets. The
Management Agreement permits NB Management to effect securities  transactions on
behalf of each  Portfolio  through  associated  persons  of NB  Management.  The
Management  Agreement  also  specifically  permits NB Management to  compensate,
through higher commissions,  brokers and dealers who provide investment research
and analysis to the  Portfolio,  but NB Management has no current plans to pay a
material amount of such compensation.

         NB Management  provides to each Portfolio,  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 the  Trust  who  are  officers,
directors, or employees of NB Management. Several individuals who are directors,
officers or employees of NB  Management  and/or  Neuberger  Berman also serve as
trustees  and/or  officers  of  the  Trust.  See  "Trustees  and  Officers."  NB
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,  except the  International  Portfolio,
which  became  subject to it on May 1, 1995,  the  Mid-Cap  Growth and  Guardian
Portfolios,  which  became  subject to it on August 20,  1997,  and the Socially
Responsive Portfolio, which became subject to it on May 28, 1998.

Management and Administration Fees

         For investment management services, Balanced, Growth, Guardian, Mid-Cap
Growth, Partners and Socially Responsive Portfolio each pays NB Management a fee
at the annual rate of 0.55% of the first $250 million of the Portfolio's average
daily  net  assets,  0.525%  of the next  $250  million,  0.50% of the next $250
million,  0.475% of the next $250 million,  0.45% of the next $500 million,  and
0.425% of  average  daily net  assets in excess of $1.5  billion.  International
Portfolio  pays NB Management a fee for  investment  management  services at the
annual rate of 0.85% of the first $250 million of the Portfolio's  average daily
net assets,  0.825% of the next $250  million,  0.80% of the next $250  million,
0.775% of the next $250  million,  0.75% of the next $500  million and 0.725% of
average  daily net assets in excess of $1.5 billion.  Limited  Maturity Bond and
Liquid Asset  Portfolio each pays NB Management a fee for investment  management
services  at  the  annual  rate  of  0.25%  of the  first  $500  million  of the
Portfolio's average daily net assets, 0.225% of the next $500 million,  0.20% of
the next  $500  million,  0.175%  of the next  $500  million,  and  0.15% of the
Portfolio's average daily net assets in excess of $2 billion.

         For  administrative  services,  each Portfolio (except Limited Maturity
Bond and Liquid Asset Portfolios) pays NB Management a fee at the annual rate of
0.30% of that Portfolio's average daily net assets. For administrative services,
Limited  Maturity Bond and Liquid Asset Portfolios each pays NB Management a fee
at the annual  rate of 0.40% of average  daily net  assets.  In  addition,  each
Portfolio  pays  certain   out-of-pocket   expenses  for  technology   used  for
shareholder  servicing  and  shareholder  communications  subject  to the  prior
approval  of an annual  budget by the  Trust's  Board of  Trustees,  including a
majority of those Trustees who are not interested  persons of the Trust or of NB
Management, and periodic reports to the Board of Trustees on actual expenses.

         During the fiscal years ended  December 31, 1999,  1998 and 1997,  each
Portfolio accrued management and  administration  fees as follows (these amounts
include management fees incurred by each Portfolio's corresponding master series
of Advisers Managers Trust.

         The Management and Administration Agreements each continue until May 1,
2001. Each 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 Trustees who are not  "interested  persons" of NB  Management or
the Trust ("Independent  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
Trustees  or by a 1940  Act  majority  vote of the  outstanding  shares  in that
Portfolio.  The Management  Agreement is terminable  with respect to a Portfolio
without  penalty on 60 days' prior  written  notice either by the Trust or by NB
Management.  The  Administration  Agreement  is  terminable  with  respect  to a
Portfolio without penalty by NB Management upon at least 120 days' prior written
notice to the  Portfolio,  and by the  Portfolio if  authorized by the Trustees,
including a majority  of the  Independent  Trustees,  on at least 30 days' prior
written notice to NB Management.  Each Agreement terminates  automatically if it
is assigned.

Expense Limitations

         All   Portfolios   (except   International   and  Socially   Responsive
Portfolios). NB Management has contractually undertaken to limit the Portfolios'
expenses  through  April 30, 2001 by  reimbursing  each  Portfolio for its total
operating expenses, excluding the compensation of NB Management (with respect to
all  Portfolios but the Guardian,  Mid-Cap Growth and Liquid Asset  Portfolios),
taxes, interest,  extraordinary expenses,  brokerage commissions and transaction
costs,  that exceed, in the aggregate,  1% per annum of the Portfolio's  average
daily net asset value.  The Guardian and Mid-Cap Growth  Portfolios have each in
turn contractually undertaken to repay through December 31, 2004, for the excess
operating  expenses borne by NB Management,  so long as the  Portfolio's  annual
operating  expenses  during that period  (exclusive  of the  compensation  of NB
Management (with respect to all Portfolios but the Guardian,  Mid-Cap Growth and
Liquid Asset Portfolios),  taxes, interest,  extraordinary  expenses,  brokerage
commissions and  transaction  costs) do not exceed the expense  limitation,  and
further provided that the  reimbursements  are made within three years after the
year in which NB Management incurred the expense.

         International  and Socially  Responsive  Portfolios.  NB Management has
contractually  undertaken to limit the  Portfolios'  expenses  through April 30,
2001 by reimbursing each Portfolio for its total operating expenses (and its pro
rata  share of its  corresponding  master  series'  total  operating  expenses),
including  compensation  to  NB  Management,   but  excluding  taxes,  interest,
extraordinary expenses and brokerage commissions, that exceed, in the aggregate,
1.70% per annum of the International  Portfolio's  average daily net asset value
and 1.50% per annum of the Socially  Responsive  Portfolio's  average  daily net
asset  value.  Each  Portfolio  has in turn  contractually  undertaken  to repay
through  December  31,  2004  for the  excess  operating  expenses  borne  by NB
Management,  so long as the Portfolio's  annual  operating  expenses during that
period  (exclusive  of taxes,  interest,  extraordinary  expenses and  brokerage
commissions) do not exceed the expense limitation, and further provided that the
reimbursements are made within three years after the year in which NB Management
incurred the expense.

         The effect of any  expense  limitation  by NB  Management  is to reduce
operating  expenses of a Portfolio and thereby increase total return.  There can
no assurance that these expense  limitation  agreements  will be continued or be
extended beyond the period indicated.

         For the year ended  December 31, 1999,  NB  Management  reimbursed  the
Liquid Asset  Portfolio  $13,038,  the Mid-Cap  Growth  Portfolio  $48,298,  the
Socially Responsive Portfolio $64,831.  Pursuant to a recoupment agreement,  the
Guardian  Portfolio repaid NB Management  $19,386 during the year ended December
31, 1999 for amounts previously reimbursed by NB Management.  For the year ended
December 31, 1998, NB Management  reimbursed the Liquid Asset Portfolio $20,005,
the Mid-Cap Growth Portfolio $58,074 and the Guardian Portfolio $50,071. For the
year ended December 31, 1997 NB Management reimbursed the Liquid Asset Portfolio
$15,867,  the Mid-Cap  Growth  Portfolio  $13,432,  and the  Guardian  Portfolio
$13,586.

Sub-Adviser

         NB Management  retains Neuberger Berman, 605 Third Avenue, New York, NY
10158-3698,  as a  sub-adviser  with  respect to each  Portfolio,  pursuant to a
Sub-Advisory  Agreement  dated May 1, 2000 that was  approved by the Trustees on
February 29, 2000.

         From May 1, 1995 through April 30, 2000, Neuberger Berman served as the
sub-adviser of the corresponding series of Advisers Managers Trust in which each
Portfolio invested its net investable assets.

         The Sub-Advisory  Agreement provides in substance that Neuberger Berman
will   furnish  to  NB   Management,   upon   reasonable   request,   investment
recommendations and research  information of the same type that Neuberger Berman
from time to time provides to its  principals  and employees for use in managing
client  accounts,  as NB  Management  reasonably  requests.  In this manner,  NB
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 numerous  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 NB Management.
The  Sub-Advisory  Agreement  provides  that the services  rendered by Neuberger
Berman will be paid for by NB 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 NB
Management.

         The  Sub-Advisory  Agreement  continues  with respect to each Portfolio
until May 1, 2001,  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  Portfolio  by the  Trustees,  or by a 1940  Act  majority  vote of the
outstanding shares of that Portfolio,  by NB Management,  or by Neuberger Berman
on not  less  than 30 nor  more  than  60  days'  prior  written  notice  to the
appropriate Portfolio.  The Sub-Advisory Agreement also terminates automatically
with respect to each Portfolio if it is assigned or if the Management  Agreement
terminates with respect to the Portfolio.

         Most money managers that come to the Neuberger Berman organization have
at least fifteen years  experience.  Neuberger  Berman and NB Management  employ
experienced professionals that work in a competitive environment.

         The  Portfolios  are  subject  to  certain  limitations  imposed on all
advisory  clients of Neuberger  Berman  (including the Portfolios,  other mutual
funds referred to below ("Other NB Funds"), and other accounts) and personnel of
Neuberger Berman and its affiliates. These include, for example, limits that may
be imposed in  certain  industries  or by certain  companies,  and  policies  of
Neuberger  Berman that limit the  aggregate  purchases,  by all  accounts  under
management, of outstanding shares of public companies.

Investment Companies Advised

         NB Management  currently serves as investment adviser or manager of the
following investment companies,  which had aggregate net assets of approximately
$18.7 billion, as of December 31, 1999.  Neuberger Berman acts as sub-adviser to
these investment companies.

</TABLE>

         The investment decisions concerning each Portfolio and the other mutual
funds  referred  to above  (collectively,  "Other NB Funds")  have been and will
continue to be made  independently of one another.  In terms of their investment
objectives,  most of the Other NB Funds differ from the  Portfolios.  Even where
the investment objectives are similar, however, the methods used by the Other NB
Funds and the Portfolios to achieve their objectives may differ.  The investment
results achieved by all of the mutual funds managed by NB Management have varied
from one another in the past and are likely to vary in the future.

         There may be occasions when a Portfolio and one or more of the Other NB
Funds or other  accounts  managed  by  Neuberger  Berman  are  contemporaneously
engaged in purchasing or selling the same  securities  from or to third parties.
When this occurs,  the transactions  are averaged as to price and allocated,  in
terms of amount, in accordance with a formula  considered to be equitable to the
funds involved.  Although in some cases this  arrangement may have a detrimental
effect  on the price or volume of the  securities  as to a  Portfolio,  in other
cases it is  believed  that a  Portfolio's  ability  to  participate  in  volume
transactions  may  produce  better  executions  for it. In any  case,  it is the
judgment of the Trustees  that the  desirability  of each  Portfolio  having its
advisory  arrangements with NB Management  outweighs any disadvantages  that may
result from contemporaneous transactions.

         The  Portfolios  are  subject  to  certain  limitations  imposed on all
advisory  clients of Neuberger  Berman  (including the Portfolios,  the Other NB
Funds,  and other managed  accounts)  and personnel of Neuberger  Berman and its
affiliates.  These include,  for example,  limits that may be imposed in certain
industries or by certain companies,  and policies of Neuberger Berman that limit
the aggregate  purchases,  by all accounts under management,  of the outstanding
shares of public companies.

                            DISTRIBUTION ARRANGEMENTS

         NB Management serves as the distributor  ("Distributor")  in connection
with the offering of each  Portfolio's  shares on a no-load basis. 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 personally, through the mails, or
by electronic means. The Distributor is each 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 Trust, on behalf of each Portfolio, and the Distributor are parties
to a Distribution Agreement dated May 1, 1995, that continues until May 1, 2001.
The Distribution  Agreement may be renewed  annually  thereafter if specifically
approved  by (1) the vote of a majority of the  Trustees or a 1940 Act  majority
vote of the Portfolio's outstanding shares and (2) the vote of a majority of the
Independent  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 Sub-Advisory Agreement.

                 ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

Share Prices and Net Asset Value

         Each  Portfolio's  shares  are  bought  or sold at a price  that is the
Portfolio's  NAV per  share.  The NAVs  for each  Portfolio  are  calculated  by
subtracting total liabilities from total assets.  Each Portfolio's per share NAV
is  calculated  by  dividing  its NAV by the  number of shares  outstanding  and
rounding the result to the nearest full cent. Each Portfolio  calculates its NAV
as of the close of regular trading on the NYSE,  usually 4 p.m. Eastern time, on
each day the NYSE is open.

         The Liquid Asset  Portfolio tries to maintain a stable NAV of $1.00 per
share.  It values  its  securities  at their  cost at the time of  purchase  and
assumes a constant amortization to maturity of any discount or premium. Although
the  Portfolio's  reliance  on  Rule  2a-7  and its  use of the  amortized  cost
valuation method should enable the Portfolio, under most conditions, to maintain
a stable $1.00 share price,  there can be no assurance it will be able to do so.
An investment in the Liquid Asset Portfolio is neither insured nor guaranteed by
the U.S. Government.

         The Equity Portfolios (except International Portfolio) value securities
(including  options)  listed on the NYSE,  the American  Stock Exchange or other
national  securities  exchanges or quoted on The Nasdaq Stock Market,  and other
securities  for which  market  quotations  are  readily  available,  at the last
reported sale price on the day the securities  are being valued.  If there is no
reported sale of such a security on that day, the security is valued at the mean
between its closing bid and asked prices on that day. These Portfolios value all
other securities and assets,  including restricted securities,  by a method that
the Trustees believe accurately reflects fair value.

         International  Portfolio values equity  securities at the last reported
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 regular trading on the
NYSE on the day the  securities  are being valued or, if there are no sales,  at
the last  available  bid price on that day. Debt  obligations  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. The Portfolio 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  believe
accurately reflects fair value.

         International  Portfolio's  securities are traded  primarily in foreign
markets which may be open 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 that  Portfolio.  Similarly,  as discussed above
under "Foreign  Securities,"  other  Portfolios may invest to varying degrees in
securities traded primarily in foreign markets,  and their share prices may also
be affected on days when shareholders have no access to the Portfolios.

         Limited Maturity Bond and Balanced (debt securities portion) Portfolios
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 believe accurately  reflects fair value. The Portfolios
periodically  verify  valuations  provided by the pricing  services.  Short-term
securities with remaining  maturities of less than 60 days may be valued at cost
which, when combined with interest earned, approximates market value.

         If NB Management believes that the price of a security obtained under a
Portfolio's  valuation  procedures  (as described  above) does not represent the
amount that the Portfolio reasonably expects to receive on a current sale of the
security,  the  Portfolio  will value the  security  based on a method  that the
Trustees believe accurately reflects fair value.

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,  (2) when
trading on the NYSE is restricted,  (3) when an emergency  exists as a result of
which  disposal by the  Portfolio of  securities  owned by it is not  reasonably
practicable or it is not  reasonably  practicable  for that Portfolio  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.

Redemptions in Kind

         Each Portfolio reserves the right, under certain  conditions,  to honor
any  request  for  redemption  (or a  combination  of  requests  from  the  same
shareholder in any 90-day period) exceeding  $250,000 or 1% of the net assets of
the  Portfolio,  whichever  is less,  by making  payment  in whole or in part in
securities  valued as described  under "Share Prices and Net Asset Value" in the
Prospectus.  Further,  each  Portfolio  may make  payment in whole or in part in
securities  if a  redeeming  shareholder  so  requests.  If  payment  is made in
securities,  a  shareholder  generally  will incur  brokerage  expenses or other
transaction  costs in converting  those securities into cash and will be subject
to fluctuation in the market prices of those securities until they are sold. The
Portfolios  do not redeem in kind under normal  circumstances,  but may do so in
the circumstances  described above in accordance with procedures  adopted by the
Board of Trustees.

                        DIVIDENDS AND OTHER DISTRIBUTIONS

         Each Portfolio  distributes to its  shareholders  (primarily  insurance
company separate accounts and Qualified Plans) substantially all of its share of
its net investment  income,  any net realized capital gains and, with respect to
all Portfolios  except the Liquid Asset  Portfolio,  any net realized gains from
foreign currency transactions,  if any, earned or realized by it. Each Portfolio
calculates its net investment  income and NAV as of the close of regular trading
on the NYSE (usually 4:00 p.m. Eastern time) on each Business Day. A Portfolio's
net investment  income  consists of all income accrued on portfolio  assets less
accrued  expenses,  but does not include net realized or unrealized  capital and
foreign currency gains or losses. Net investment income and net gains and losses
are reflected in a Portfolio's NAV until they are  distributed.  With respect to
the Mid-Cap Growth, Guardian, Growth, Partners, Balanced, Limited Maturity Bond,
Socially Responsive 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 net investment  income 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

         Set forth below is a  discussion  of certain  U.S.  federal  income tax
issues concerning the Portfolios and the purchase, ownership, and disposition of
Portfolio  shares.  This  discussion  does not purport to be complete or to deal
with all aspects of federal income taxation that may be relevant to shareholders
in  light of their  particular  circumstances.  This  discussion  is based  upon
present  provisions  of the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code"), the regulations promulgated thereunder, and judicial and administrative
ruling  authorities,  all of which are  subject to change,  which  change may be
retroactive.  Prospective  investors  should consult their own tax advisers with
regard  to  the  federal  tax  consequences  of  the  purchase,   ownership,  or
disposition of Portfolio shares,  as well as the tax consequences  arising under
the laws of any state, foreign country, or other taxing jurisdiction.

Taxation of Each Portfolio

         Subchapter M

         To  continue  to qualify for  treatment  as a RIC under the 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 stock,  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 such stock,  securities  or  currencies  ("Income
Requirement");  and (2) 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,  securities of other RICs 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 that 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 or securities of other RICs) of any one
issuer (together with the 50% requirement,  the "Diversification  Requirement").
Each  Portfolio  intends to satisfy  the  Distribution  Requirement,  the Income
Requirement,  and the  Diversification  Requirement.  If a  Portfolio  failed to
qualify for  treatment as a RIC for any taxable  year,  it would be taxed on the
full amount of its taxable income for that year without being able to deduct the
distributions it makes to its shareholders and the shareholders  would treat all
those distributions,  including distributions of net capital gain (the excess of
net long-term capital gain over net short-term capital loss), as dividends (that
is, ordinary income) to the extent of the Portfolio's earnings and profits.

         A Portfolio will be subject to a  nondeductible  4% excise tax ("Excise
Tax") to the  extent  it fails to  distribute  by the end of any  calendar  year
substantially  all of its  ordinary  income for that year and  capital  gain net
income for the one-year  period ending on October 31 of that year,  plus certain
other amounts.  To avoid application of the Excise Tax, the Portfolios intend to
make distributions in accordance with the calendar year requirement.

         A  distribution  will be treated as paid on  December  31 of a calendar
year if it is declared by a Portfolio  in October,  November or December of that
year with a record date in such a month and paid by the Portfolio during January
of the following year.

         The Portfolios serve as the underlying investments for variable annuity
contracts and variable life insurance  policies  ("Variable  Contracts")  issued
through separate  accounts of the life insurance  companies which may or may not
be  affiliated.  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
Portfolios),  which are in addition to the diversification  requirements imposed
on the  Portfolios  by the 1940 Act and  Subchapter  M of the Code.  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  Portfolio  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.

         Tax Aspects of the Investments of the Portfolios

         Dividends,  interest,  and in some cases,  capital gains  received by a
Portfolio  may be subject  to income,  withholding,  or other  taxes  imposed by
foreign countries and U.S.  possessions that would reduce the yield and/or total
return on its  securities.  Tax conventions  between  certain  countries and the
United States may reduce or eliminate  these foreign  taxes,  however,  and many
foreign countries do not impose taxes on capital gains in respect of investments
by foreign investors.

         The  Equity  Portfolios  may  invest in the stock of  "passive  foreign
investment companies" ("PFICs"). A PFIC is any foreign corporation (with certain
exceptions) 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  Portfolio  holds  stock of a PFIC,  it 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  it  distributes  that  income to its
shareholders  (assuming  the  Portfolio  qualifies  as  a  regulated  investment
company).

         In general,  under the PFIC rules, an excess distribution is treated as
having been realized ratably over the period during which the Portfolio held the
PFIC shares.  A Portfolio will itself be subject to tax on the portion,  if any,
of an excess  distribution that is so allocated to prior Portfolio taxable years
and an interest  factor will be added to the tax, as if the tax had been payable
in such prior taxable years.  Certain  distributions from a PFIC as well as gain
from the  sale of PFIC  shares  are  treated  as  excess  distributions.  Excess
distributions  are   characterized  as  ordinary  income  even  though,   absent
application  of the PFIC rules,  certain  excess  distributions  might have been
classified as capital gain.

         If a  Portfolio  invests  in a PFIC and  elects  to treat the PFIC as a
qualified electing fund ("QEF"), then in lieu of incurring the foregoing tax and
interest  obligation,  the Portfolio would be required to include in income each
year its pro rata share of the  Portfolio's  pro rata share of the QEF'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 and avoid
imposition  of the  excise  tax -- even if  those  earnings  and  gain  were not
received  by the  Portfolio  from the  QEF.  In most  instances  it will be very
difficult,  if  not  impossible,  to  make  this  election  because  of  certain
requirements thereof.

         A holder of stock in a PFIC  generally may elect to include in ordinary
income for each taxable year the excess, if any, of the fair market value of the
stock  over its  adjusted  basis  as of the end of that  year.  Pursuant  to the
election, a deduction (as an ordinary,  not capital, loss) also would be allowed
for the excess,  if any, of the holder's  adjusted  basis in PFIC stock over the
fair market value thereof as of the taxable year-end,  but only to the extent of
any net  mark-to-market  gains with respect to that stock included in income for
prior taxable years under the election (and under  regulations  proposed in 1992
that provided a similar  election  with respect to the stock of certain  PFICs).
The  adjusted  basis in each  PFIC's  stock  subject  to the  election  would be
adjusted  to  reflect  the  amounts  of income  included  and  deductions  taken
thereunder.  Any  gain on the sale of PFIC  stock  subject  to a  mark-to-market
election would be treated as ordinary income.

         The use by the Portfolios  (except  Liquid Asset  Portfolio) 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  amount,   character  and  timing  of
recognition of the gains and losses they realize in connection therewith.  Gains
from the  disposition of foreign  currencies  (except  certain gains that may be
excluded by future regulations), and gains from Hedging Instruments derived by a
Portfolio  with respect to its business of  investing in  securities  or foreign
currencies, will qualify as permissible income under the Income Requirement.

         Exchange-traded futures contracts, certain options, and certain forward
contracts  constitute  "Section  1256  Contracts."  Section 1256  Contracts  are
required  to be  "marked-to-market"  (that is,  treated  as having  been sold at
market  value) for  federal  income  tax  purposes  at the end of a  Portfolio's
taxable year.  Sixty  percent of any net 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.  Section 1256
contracts  also may be  marked-to-market  for purposes of the excise tax.  These
rules may operate to increase  the amount that a Portfolio  must  distribute  to
satisfy the Distribution Requirement,  which will be taxable to the shareholders
as ordinary  income,  and to increase  the net capital  gain  recognized  by the
Portfolio,  without  in  either  case  increasing  the  cash  available  to  the
Portfolio.  A  Portfolio  may elect to  exclude  certain  transactions  from the
operation of section 1256,  although  doing so may have the effect of increasing
the relative  proportion  of net  short-term  capital gain  (taxable as ordinary
income)  and/or  increasing  the amount of dividends  that such  Portfolio  must
distribute to meet the  Distribution  Requirement and to avoid imposition of the
excise tax.

         Transactions in options,  futures and forward contracts undertaken by a
Portfolio  may  result in  "straddles"  for  federal  income tax  purposes.  The
straddle  rules may affect the  character  of gains (or losses)  realized by the
Portfolio,  and losses realized by the Portfolio on positions that are part of a
straddle may be deferred under the straddle rules,  rather than being taken into
account in  calculating  the taxable  income for the  taxable  year in which the
losses are realized.  In addition,  certain carrying charges (including interest
expense)  associated  with  positions  in a  straddle  may  be  required  to  be
capitalized  rather  than  deducted  currently.   Certain  elections  that  each
Portfolio  may make with respect to its straddle  positions  may also affect the
amount,  character  and timing of the  recognition  of gains or losses  from the
affected positions.

         Because only a few  regulations  implementing  the straddle  rules have
been  promulgated,  the consequences of such  transactions to each Portfolio are
not entirely  clear.  The straddle  rules may increase the amount of  short-term
capital gain realized by each Portfolio,  which is taxed as ordinary income when
distributed  to  shareholders.  Because  application  of the straddle  rules may
affect the  character of gains or losses,  defer losses  and/or  accelerate  the
recognition of gains or losses from the affected straddle positions,  the amount
which must be  distributed  to  shareholders  as  ordinary  income or  long-term
capital gain may be increased or decreased  substantially  as compared to a fund
that did not engage in such transactions.

         Section 988 of the Code also may apply to forward contracts and options
on foreign  currencies.  Under  section 988 each foreign  currency  gain or loss
generally is computed  separately and treated as ordinary income or loss. In the
case of overlap between section 1256 and 988, special  provisions  determine the
character and timing of any income, gain or loss.

         When a covered call option  written (sold) by a Portfolio  expires,  it
realizes  a  short-term  capital  gain  equal to the  amount of the  premium  it
received for writing the option.  When a Portfolio  terminates  its  obligations
under  such an option by  entering  into a closing  transaction,  it  realizes a
short-term capital gain (or loss),  depending on whether the cost of the closing
transaction  is less (or more) than the  premium it  received  when it wrote the
option.  When a covered  call option  written by a Portfolio is  exercised,  the
Portfolio is treated as having sold the underlying security, producing long-term
or  short-term  capital  gain or loss,  depending  on the holding  period of the
underlying  security  and  whether the sum of the option  price  received on the
exercise plus the premium received when it wrote the option is more or less than
the basis of the underlying security.

         If a Portfolio has an "appreciated financial position" -- generally, an
interest (including an interest through an option,  futures or forward contract,
or short sale) with respect to any stock,  debt instrument (other than "straight
debt"),  or  partnership  interest  the fair market  value of which  exceeds its
adjusted  basis  -- and  enters  into a  "constructive  sale"  of  the  same  or
substantially similar property,  the Portfolio will be treated as having made an
actual sale thereof,  with the result that gain will be recognized at that time.
A constructive sale generally  consists of a short sale, an offsetting  notional
principal  contract  (e.g., a swap contract),  or a futures or forward  contract
entered  into by a Portfolio  or a related  person  with  respect to the same or
substantially  similar  property.  In  addition,  if the  appreciated  financial
position  is  itself  a  short  sale  or  such a  contract,  acquisition  of the
underlying  property  or  substantially  identical  property  will be  deemed  a
constructive  sale. The foregoing will not apply,  however,  to any  transaction
during any taxable year that otherwise  would be treated as a constructive  sale
if the  transaction  is closed within 30 days after the end of that year and the
Portfolio holds the appreciated  financial  position  unhedged for 60 days after
that closing (i.e., at no time during that 60-day period is the Portfolio's risk
of  loss  regarding  that  position  reduced  by  reason  of  certain  specified
transactions with respect to substantially  identical or related property,  such
as having an option to sell,  being  contractually  obligated to sell,  making a
short  sale,  or  granting  an option to buy  substantially  identical  stock or
securities).

         Gains or losses  attributable  to  fluctuations in exchange rates which
occur  between  the time a  Portfolio  accrues  income or other  receivables  or
accrues expenses or other liabilities  denominated in a foreign currency and the
time the Portfolio  actually  collects such receivables or pays such liabilities
generally  are  treated as  ordinary  income or  ordinary  loss.  Similarly,  on
disposition of some  investments,  including debt securities and certain forward
contracts  denominated in a foreign  currency,  gains or losses  attributable to
fluctuations  in the value of the foreign  currency  between the acquisition and
disposition  of the position  also are treated as ordinary  gain or loss.  These
gains and losses,  referred to under the Code as "Section  988" gains or losses,
increase or decrease the amount of the  Portfolio's  investment  company taxable
income available to be distributed to its  shareholders as ordinary  income.  If
Section 988 losses  exceed other  investment  company  taxable  income  during a
taxable  year,  the  Portfolio  would not be able to make any ordinary  dividend
distributions,  or  distributions  made before the losses were realized would be
recharacterized  as a return  of  capital  to  shareholders,  rather  than as an
ordinary dividend,  reducing each shareholder's  basis in his or her Portfolio's
shares.

         Limited  Maturity  Bond and  Liquid  Asset  Portfolios  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"),  at 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  Portfolio
(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.  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.
In lieu of treating the  disposition  gain as described  above,  a Portfolio may
elect to include market discount in its gross income currently, for each taxable
year to which it is attributable.

         Partners, Balanced, and Socially Responsive Portfolios each may acquire
zero  coupon  or other  securities  issued  with  OID.  As the  holder  of those
securities,  each  Portfolio  must take into  income the OID and other  non-cash
income  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 investment
company  taxable  income  to  satisfy  the  Distribution  Requirement  and avoid
imposition  of the  excise  tax,  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 it actually  receives.  Those  distributions  will be made from a
Portfolio's  cash  assets or, if  necessary,  from the  proceeds  of the sale of
portfolio securities. A Portfolio may realize capital gains or losses from those
sales,  which would increase or decrease its  corresponding  investment  company
taxable income and/or net capital gain.

                             PORTFOLIO TRANSACTIONS

         Neuberger Berman acts as each Portfolio's principal broker (except with
respect  to  International  Portfolio)  to the  extent a  broker  is used in the
purchase and sale of portfolio  securities (other than certain securities traded
on the OTC  market).  Neuberger  Berman  may  act as  broker  for  International
Portfolio.  Neuberger Berman receives brokerage  commissions for these services.
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 Portfolios  typically 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 the
prices quoted by  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 Portfolio's 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,  NB 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 Portfolio
or NB  Management.  Some  of  these  research  services  may be of  value  to NB
Management in advising its various clients  (including the Portfolios)  although
not all of these services are necessarily  used by NB Management in managing the
Portfolios.  Under  certain  conditions,  a Portfolio  may pay higher  brokerage
commissions in return for brokerage and research services, although no Portfolio
has a current  arrangement  to do so. In any case,  each  Portfolio  may  effect
principal  transactions  with a dealer  who  furnishes  research  services,  may
designate  any  dealer  to  receive  selling  concessions,  discounts,  or other
allowances,  or may  otherwise  deal  with any  dealer  in  connection  with the
acquisition of securities in underwritings.

$2,890, of which $2,542 was paid to Neuberger Berman.  Transactions in which the
corresponding  series used  Neuberger  Berman as broker  comprised  90.9% of the
aggregate  dollar amount of  transactions  involving the payment of commissions,
and 88.0% of the  aggregate  brokerage  commissions  paid by it during  the year
ended  December  31,  1999.  100.0%  of the $347  paid to other  brokers  by the
corresponding  series  during the year ended  December  31,  1999  (representing
commissions on transactions  involving  approximately  $189,545) was directed to
those brokers because of research services they provided.  During the year ended
December 31, 1999 the series acquired securities of the following of its regular
B/Ds:  Goldman,  Sachs & Co; and State  Street Bank and Trust  Company;  at that
date, the series did not hold any securities of its regular B/Ds.

         Insofar as portfolio  transactions  of Partners  Portfolio  result from
active management of equity securities, and insofar as portfolio transactions of
Growth  Portfolio  and Mid-Cap  Growth  Portfolio  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  Portfolio 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  may,  from time to time, be loaned by the Equity
Portfolios to Neuberger Berman in accordance with the terms and conditions of an
order issued by the SEC. The order exempts such  transactions from provisions of
the 1940 Act that would otherwise prohibit such transactions, subject to certain
conditions.  In accordance with the order, securities loans made by a Portfolios
to Neuberger  Berman are fully  secured by cash  collateral.  The portion of the
income on the cash collateral which may be shared with Neuberger Berman is to be
determined by reference to concurrent  arrangements between Neuberger Berman and
non-affiliated  lenders  with  which it  engages  in  similar  transactions.  In
addition, where Neuberger Berman borrows securities from a Portfolio in order to
re-lend  them to Other NB Funds,  Neuberger  Berman may be  required to pay that
Portfolio,  on a quarterly basis,  certain of the earnings that Neuberger Berman
otherwise  has derived  from the  re-lending  of the borrowed  securities.  When
Neuberger  Berman  desires to borrow a security that a Portfolio has indicated a
willingness  to lend,  Neuberger  Berman  must borrow  such  security  from that
Portfolio,  rather  than from a  unaffiliated  lender,  unless the  unaffiliated
lender is willing to lend such security on more favorable terms (as specified in
the order) than that Portfolio.  If, in any month, a Portfolio's  expense exceed
its income in any securities loan transaction with Neuberger  Berman,  Neuberger
Berman must reimburse that Portfolio for such loss.

         A committee of  Independent  Trustees from time to time reviews,  among
other things, information relating to securities loans by the Portfolios.

         In effecting securities transactions, each Portfolio 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
Portfolio plans to continue to use Neuberger  Berman as its broker where, in the
judgment of NB Management,  that firm is able to obtain a price and execution at
least as favorable as other qualified  brokers.  To the  Portfolio's  knowledge,
however,  no affiliate of any Portfolio receives give-ups or reciprocal business
in connection with their securities transactions.

         The use of  Neuberger  Berman as a broker for a Portfolio 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 retaining  compensation for executing  exchange  transactions for
accounts  that  they or their  affiliates  manage,  except  where  they have the
authorization of the persons authorized to transact business for the account and
comply with certain  annual  reporting  requirements.  The Board of Trustees has
expressly  authorized Neuberger Berman to retain such compensation and Neuberger
Berman has agreed to comply with the reporting requirements of Section 11(a).

         Under the 1940 Act, commissions paid by a Portfolio 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  Portfolio's  policy that the commissions to be paid to
Neuberger Berman must, in NB 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 Trustees not to be comparable to the
Portfolio.  The Portfolio 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 Portfolio's
account, unless an appropriate exemption is available.

         A committee of  Independent  Trustees from time to time reviews,  among
other  things,  information  relating to the  commissions  charged by  Neuberger
Berman  to  the  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 Portfolios must be reviewed and
approved no less often than annually by a majority of the Independent Trustees.

         To  ensure  that  accounts  of  all  investment  clients,  including  a
Portfolio,  are  treated  fairly in the event  that  Neuberger  Berman  receives
transaction  instructions  regarding  a  security  for more than one  investment
account at or about the same time, Neuberger Berman may combine orders placed on
behalf of clients,  including advisory accounts in which affiliated persons have
an investment interest,  for the purpose of negotiating brokerage commissions or
obtaining a more favorable price.  Where  appropriate,  securities  purchased or
sold may be  allocated,  in  terms  of  amount,  to a  client  according  to the
proportion  that the  size of the  order  placed  by that  account  bears to the
aggregate size of orders contemporaneously placed by the other accounts, subject
to de minimis  exceptions.  All  participating  accounts will pay or receive the
same price.

         Under policies  adopted by the Board of Trustees,  Neuberger Berman may
enter into agency  cross-trades on behalf of a Portfolio.  An agency cross-trade
is a securities transaction in which the same broker acts as agent on both sides
of the  trade and the  broker or an  affiliate  has  discretion  over one of the
participating  accounts.  In this  situation,  Neuberger  Berman  would  receive
brokerage  commissions  from both  participants in the trade.  The other account
participating  in an agency  cross-trade  with a Portfolio  cannot be an account
over which Neuberger Berman  exercises  investment  discretion.  A member of the
Board  of  Trustees  who  is  not  affiliated  with  Neuberger   Berman  reviews
confirmations of each agency cross-trade that the Portfolios participate in.

         Each  Portfolio  expects that it will  continue to execute a portion of
its transactions through brokers other than Neuberger Berman. In selecting those
brokers,  NB 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 officers of NB  Management  and employees of
Neuberger Berman who are portfolio  managers of some of the Portfolios and Other
NB Funds  (collectively,  "NB 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.  Based on this
evaluation, the committee establishes a list and projected rankings 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 NB 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 NB Funds and/or the Managed Accounts;  and (3) the aggregate amount
of  brokerage  commissions  generated by  transactions  for the NB Funds and the
Managed  Accounts may change  substantially  from one semi-annual  period to the
next.

         The  commissions  paid to a broker other than  Neuberger  Berman may be
higher than the amount another firm might charge if NB 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.  NB
Management  believes that those research  services  provide the Portfolios  with
benefits by supplementing the information  otherwise available to NB Management.
That  research  information  may be used by NB  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 NB
Management from brokers effecting portfolio  transactions on behalf of the Other
NB Funds and by Neuberger Berman from brokers executing  portfolio  transactions
on behalf of the Managed Accounts may be used for the Portfolio's benefit.

         The following  individuals  are the persons  primarily  responsible for
making  decisions  as to  specific  action  to be  taken  with  respect  to  the
investment  portfolios  of the  indicated  Portfolios:  Theodore P. Giuliano and
Catherine  Waterworth - Balanced (debt  securities  portion),  Limited  Maturity
Bond,  and Liquid  Asset (with  respect to Mr.  Giuliani);  Josephine  Mahaney -
Liquid Asset; Kevin L. Risen and Allan R. White III - Guardian;  Valerie Chang -
International;  Jennifer K. Silver and Brooke A. Cobb - Growth; Balanced (equity
securities portion) and Mid-Cap Growth;  Robert I. Gendelman and S. Basu Mullick
- -  Partners;  and  Janet  W.  Prindle  -  Socially  Responsive.  Each  of  these
individuals  is a Vice  President of NB  Management  and a Managing  Director or
officer of Neuberger Berman. Each of them has full authority to take action with
respect  to  portfolio  transactions  and  may or may  not  consult  with  other
personnel  of NB  Management  prior to taking  such  action.  If Ms.  Prindle is
unavailable  to  perform  her   responsibilities,   Robert  Ladd  and/or  Ingrid
Saukaitis,  each of whom  is a Vice  President  of NB  Management,  will  assume
responsibility for the management of Socially Responsive Portfolio. If Ms. Chang
is  unavailable  to perform her  responsibilities,  Benjamin  E.  Segal,  a Vice
President of NB Management, will assume the responsibility for the management of
International Portfolio.

                               PORTFOLIO TURNOVER

         The portfolio turnover rate is calculated by dividing the lesser of the
cost of the securities purchased or the proceeds from the securities sold by the
Portfolio  during the fiscal  year (other than  securities,  including  options,
foreign  financial futures  contracts and forward  contracts,  whose maturity or
expiration date at the time of acquisition was one year or less), divided by the
month-end average monthly value of such securities owned by the Portfolio 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.  Each Portfolio's report shows the investments owned
by it 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.

                       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 1940 Act as a diversified,  open-end management  investment
company,  commonly  known  as  a  mutual  fund.  The  Trust  has  nine  separate
Portfolios.  The  Trustees 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.  As discussed  above under  "Investment
Information",  through April 30, 2000,  each  Portfolio  invested all of its net
investable assets in its corresponding master series of Advisers Managers Trust,
in each case  receiving a beneficial  interest in that series.  Beginning May 1,
2000, each Portfolio invests directly in its own securities portfolio.

         NB  Management  and Neuberger  Berman serve as  investment  manager and
sub-advisor,  respectively,  to other mutual funds,  and the investments for the
Portfolios  (through  their  corresponding  series)  are  managed  by  the  same
portfolio  managers who manage one or more other mutual funds, that have similar
names,  investment  objectives and  investment  styles as each Portfolio and are
offered  directly to the public by means of separate  prospectuses.  These other
mutual funds are not part of the Trust.  You should be aware that each Portfolio
is likely to differ from the other mutual funds in size, cash flow pattern,  and
certain tax matters, and may differ in risk/return characteristics. Accordingly,
the portfolio  holdings and performance of the Portfolios may vary from those of
the other mutual funds with similar names.

         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  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.

                          CUSTODIAN AND TRANSFER AGENT

         Each Portfolio has selected State Street Bank and Trust Company ("State
Street"), 225 Franklin Street, Boston,  Massachusetts 02110 as custodian for its
securities and cash. State Street also serves as each Portfolio's Transfer Agent
and  shareholder  servicing  agent,  administering  purchases and redemptions of
Trust shares through its Boston Service Center.

                              INDEPENDENT AUDITORS

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

                                  LEGAL COUNSEL

         Each  Portfolio has selected  Dechert Price & Rhoads,  1775 Eye Street,
N.W., Washington, D.C. 20006 as legal counsel.

                             REGISTRATION STATEMENT

         This SAI and Prospectus do not contain all the information  included in
the Trust's  registration  statement  filed with the SEC under the 1933 Act with
respect to the securities  offered by the  Prospectus.  Certain  portions of the
registration  statement have been omitted pursuant to SEC rules and regulations.
The  registration  statement,  including the exhibits  filed  therewith,  may be
examined at the SEC's  offices in  Washington,  D.C. The SEC maintains a Website
(http://www.sec.gov)  that contains this SAI, material incorporated by reference
and other information regarding the Portfolios.

         Statements  contained in this SAI and  Prospectus as to the contents of
any contract or other document referred to are not necessarily complete. In each
instance  reference is made to the copy of the contract or other  document filed
as an exhibit to the registration statement, each such statement being qualified
in all respects by such reference.

                              FINANCIAL STATEMENTS

         The  audited  financial  statements,  notes  to the  audited  financial
statements,  and reports of the  independent  auditors  contained  in the annual
reports to the  shareholders of the Trust for the fiscal year ended December 31,
1999 for Neuberger Berman Advisers Management Trust (with respect to each of the
Balanced  Portfolio,  Mid-Cap  Growth  Portfolio,   Guardian  Portfolio,  Growth
Portfolio,  Limited Maturity Bond Portfolio,  Liquid Asset  Portfolio,  Partners
Portfolio and Socially  Responsive  Portfolio),  and for Advisers Managers Trust
(with  respect  to each of the AMT  Balanced  Investments,  AMT  Mid-Cap  Growth
Investments,  AMT  Guardian  Investments,  AMT Growth  Investments,  AMT Mid-Cap
Growth Investments,  AMT Liquid Asset Investments,  AMT Partners Investments and
AMT Socially  Responsive  Investments) are  incorporated  into this Statement of
Additional  Information  by  reference  to each  Portfolio's  Annual  Report  to
shareholders for the fiscal year ended December 31, 1999.

           APPENDIX A: RATINGS OF CORPORATE BONDS AND COMMERCIAL PAPER

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; and

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