PROSPECTUS                                                    December 31, 1998
                             AMERICAN SKANDIA TRUST
                 One Corporate Drive, Shelton, Connecticut 06484
- --------------------------------------------------------------------------------
American Skandia Trust (the "Trust") is a managed,  open-end  investment company
whose separate  portfolios  ("Portfolios")  are  diversified,  unless  otherwise
indicated.  The Trust seeks to meet the differing  investment  objectives of its
Portfolios.  The  Portfolios  as of  the  date  of  this  Prospectus  and  their
respective investment objectives are as follows:

AST JanCap Growth Portfolio seeks growth of capital in a manner  consistent with
preservation  of capital.  AST Janus  Small-Cap  Growth  Portfolio seeks capital
appreciation. T. Rowe Price International Equity Portfolio seeks total return on
its assets  from  long-term  growth of capital  and income  principally  through
investments in common stocks of established,  non-U.S.  companies. T. Rowe Price
International  Bond  Portfolio  seeks to provide high current income and capital
appreciation by investing in high-quality, non dollar-denominated government and
corporate bonds outside the United States.  AST INVESCO Equity Income  Portfolio
seeks high current income while following sound  investment  practices.  Capital
growth potential is an additional, but secondary, consideration in the selection
of portfolio  securities.  AST Neuberger  Berman Mid-Cap Value  Portfolio  seeks
capital growth.

Investments in the Trust are neither insured nor guaranteed by the United States
Government.  Such  investments  are not bank  deposits,  and are not insured by,
guaranteed by, obligations of, or otherwise supported by, any bank.

This Prospectus sets forth concisely the information that a prospective investor
should know before  investing  in shares of the Trust and should be retained for
future reference. A Statement of Additional Information, dated December 31, 1998
(the "SAI"),  containing  additional  information about the Trust has been filed
with the Securities and Exchange  Commission  (the  "Commission")  and is hereby
incorporated  by reference  into this  Prospectus.  The Trust's SAI is available
without  charge  upon  request  to the Trust at the above  address or by calling
(800) 752-6342.  The Commission maintains a Web site (http:/  /www.sec.gov) that
contains the SAI,  material  incorporated  by reference,  and other  information
regarding the Trust.

THESE  SECURITIES  HAVE NOT BEEN APPROVED OR  DISAPPROVED  BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION OR
ANY STATE  SECURITIES  COMMISSION  PASSED UPON THE  ACCURACY OR ADEQUACY OF THIS
PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

Shares of the Trust are  available  to,  and are  marketed  as a pooled  funding
vehicle for, life  insurance  companies  ("Participating  Insurance  Companies")
writing variable annuity contracts and variable life insurance  policies.  As of
the date of this  Prospectus,  the only  Participating  Insurance  Companies are
American Skandia Life Assurance  Corporation and Kemper Investors Life Insurance
Company.  From time to time,  however,  the Trust may enter  into  participation
agreements with other Participating Insurance Companies. The profit sharing plan
covering  employees  of American  Skandia  Life  Assurance  Corporation  and its
affiliates (the "Skandia Qualified Plan"),  which is a retirement plan qualified
under Section 401(a) of the Internal Revenue Code of 1986, as amended,  may also
directly own shares of the Trust.  The Trust sells and redeems its shares at net
asset value without any sales  charges,  commissions  or redemption  fees.  Each
variable  annuity  contract and variable life insurance policy involves fees and
expenses  not  described  in  this  Prospectus.  Certain  Portfolios  may not be
available in connection with a particular  variable annuity contract or variable
life insurance  policy or the Qualified Plan.  Please read the Prospectus of the
variable  annuity  contracts  and variable  life  insurance  policies  issued by
Participating  Insurance  Companies for information  regarding contract fees and
expenses and any restrictions on purchases.

INVESTMENT  OBJECTIVES AND POLICIES:  The investment  objective and policies for
each of the Portfolios are described below, and should be considered separately.
While certain  policies apply to all Portfolios,  generally each Portfolio has a
different  investment  objective and certain policies may vary. As a result, the
risks,  opportunities and returns in each Portfolio may differ. Those investment
policies  specifically  labeled  as  "fundamental"  may not be  changed  without
approval  of  the  shareholders  of the  affected  Portfolio.  Each  Portfolio's
investment objective or investment policies,  unless otherwise specified, is not
a fundamental policy and may be changed without shareholder approval.  There can
be no assurance that any Portfolio's investment objective will be achieved. Risk
factors  in  relation  to  various  securities  and  instruments  in  which  the
Portfolios  may invest are described in the sections of this  Prospectus and the
Trust's SAI entitled "Certain Risk Factors and Investment  Methods."  Additional
information  about the investment  objectives and policies of each Portfolio may
be found in the Trust's SAI under "Investment Objectives and Policies."

     American  Skandia  Investment  Services,   Incorporated  ("ASISI")  is  the
investment  manager  ("Investment  Manager")  for the  Trust.  Currently,  ASISI
engages a sub-advisor  ("Sub-advisor")  for each Portfolio.  The Sub-advisor for
each Portfolio is as follows: (a) Janus Capital  Corporation:  AST JanCap Growth
Portfolio,   AST  Janus  Small-Cap  Growth  Portfolio;  (b)  Rowe  Price-Fleming
International,  Inc.: AST T. Rowe Price International  Equity Portfolio,  AST T.
Rowe Price  International  Bond  Portfolio;  (c) INVESCO Funds Group,  Inc.: AST
INVESCO Equity Income Portfolio;  (d) Neuberger Berman Management  Incorporated:
AST Neuberger Berman Mid-Cap Value Portfolio.

         Subject to approval  of the Board of  Trustees of the Trust,  the Trust
may add one or more  portfolios  and may cease to offer one or more  portfolios,
any such cessation to be subject to obtaining required regulatory approvals.

AST JanCap Growth Portfolio:

Investment  Objective:  The  investment  objective  of the  Portfolio is to seek
growth of capital  in a manner  consistent  with the  preservation  of  capital.
Realization  of income is not a  significant  investment  consideration  and any
income realized on the Portfolio's investments, therefore, will be incidental to
the Portfolio's objective. This is a fundamental objective of the Portfolio.

Investment Policies:

         The  Portfolio  will pursue its  objective  by  investing  primarily in
common stocks. Common stock investments will be in industries and companies that
the Sub-advisor  believes are  experiencing  favorable demand for their products
and  services,  and which  operate in a  favorable  competitive  and  regulatory
environment.  Although  the  Sub-advisor  expects to invest  primarily in equity
securities,  the Sub-advisor may increase the Portfolio's  cash position without
limitation  when the Sub-advisor is of the opinion that  appropriate  investment
opportunities for capital growth with desirable risk/reward  characteristics are
unavailable.  The  Portfolio  may also  invest to a lesser  degree in  preferred
stocks, convertible securities, warrants, and debt securities when the Portfolio
perceives an opportunity  for capital growth from such securities or so that the
Portfolio  may receive a return on its idle cash.  The Portfolio may also invest
in money  market  funds  managed by the  Sub-advisor  as a means of  receiving a
return on idle cash.  Debt  securities  that the Portfolio may purchase  include
corporate  bonds and  debentures  (not to exceed 5% of net assets in bonds rated
below  investment  grade),  government  securities,  mortgage- and  asset-backed
securities,  zero-coupon bonds,  indexed/structured notes, high-grade commercial
paper,  certificates of deposit and repurchase  agreements.  For a discussion of
other  investment   companies   (including  money  market  funds),   lower-rated
securities,  mortgage- and  asset-backed  securities and zero coupon bonds,  see
this  Prospectus  and the Trust's SAI under "Certain Risk Factors and Investment
Methods."

         Although it is the general policy of the Portfolio to purchase and hold
securities  for capital  growth,  changes in the  Portfolio  will be made as the
Sub-advisor  deems  advisable.  For example,  portfolio  changes may result from
liquidity needs,  securities  having reached a price objective,  or by reason of
developments  not  foreseen  at the time of the  original  investment  decision.
Portfolio  changes may be effected  for other  reasons.  In such  circumstances,
investment income will increase and may constitute a large portion of the return
on the Portfolio and the Portfolio will not  participate in the market  advances
or declines to the extent that it would if it were fully invested.

         The Portfolio may invest in "special  situations"  from time to time. A
"special  situation"  arises  when,  in  the  opinion  of the  Sub-advisor,  the
securities of a particular  company will be recognized  and  appreciate in value
due to a specific development, such as a technological breakthrough,  management
change or new  product  at that  company.  Investment  in  "special  situations"
carries an additional risk of loss in the event that the anticipated development
does not occur or does not attract the expected attention.

         Foreign  Securities.  The  Portfolio  may also  purchase  securities of
foreign  issuers,  including  foreign equity and debt  securities and depositary
receipts.  Foreign  securities  are selected on a  stock-by-stock  basis without
regard to any defined allocation among countries or geographic regions. However,
certain  factors  such as  expected  levels of  inflation,  government  policies
influencing business  conditions,  the outlook for currency  relationships,  and
prospects for economic growth among  countries,  regions or geographic areas may
warrant greater  consideration in selecting  foreign stocks. No more than 25% of
the  Portfolio's  assets may be invested in foreign  securities  denominated  in
foreign currency and not publicly traded in the United States.  For a discussion
of  depositary   receipts  and  the  risks  involved  in  investing  in  foreign
securities, including the risk of currency fluctuations, see this Prospectus and
the Trust's SAI under "Certain Risk Factors and Investment Methods."

         Futures,  Options and Other Derivative Instruments.  Subject to certain
limitations,  the  Portfolio  may  purchase  and write  options  on  securities,
financial indices,  and foreign currencies,  and may invest in futures contracts
on securities,  financial indices, and foreign currencies ("futures contracts"),
options on  futures  contracts,  forward  contracts  and swaps and  swap-related
products.  These  instruments  will be used  primarily to hedge the  Portfolio's
positions  against potential  adverse  movements in securities  prices,  foreign
currency markets or interest rates. To a limited extent,  the Portfolio may also
use  derivative  instruments  for  non-hedging  purposes such as increasing  the
Portfolio's  income or otherwise  enhancing  return.  The Portfolio will not use
futures  contracts  and  options  for  leveraging  purposes.  There  can  be  no
assurance,  however,  that the use of these  instruments  by the Portfolio  will
assist it in achieving its investment  objective.  The use of futures,  options,
forward  contracts and swaps involves  investment risks and transaction costs to
which the Portfolio would not be subject absent the use of these strategies. The
Sub-advisor may, from time to time, at its own expense, call upon the experience
of experts to assist it in implementing these strategies. The Portfolio may also
use a  variety  of  currency  hedging  techniques,  including  forward  currency
contracts,  to manage exchange rate risk with respect to investments  exposed to
foreign  currency  fluctuations.  For an  additional  discussion  of futures and
options transactions and the risks involved therein, see this Prospectus and the
Trust's SAI under "Certain Risk Factors and Investment Methods."

         Repurchase  Agreements.  Subject to guidelines promulgated by the Board
of Trustees of the Trust,  the Portfolio may enter into  repurchase  agreements,
which  involve the purchase of a security by the  Portfolio  and a  simultaneous
agreement  (generally with a bank or dealer) to repurchase the security from the
Portfolio  at a  specified  date  or upon  demand.  The  Portfolio's  repurchase
agreements will at all times be fully  collateralized.  Pursuant to an exemptive
order granted by the Securities and Exchange Commission, the Portfolio and other
funds advised by the Sub-advisor  may invest in repurchase  agreements and other
money market  instruments  through a joint trading account.  For a discussion of
repurchase  agreements and the risks involved therein, see this Prospectus under
"Certain Risk Factors and Investment Methods."

         Reverse Repurchase Agreements. The Portfolio is permitted to enter into
reverse repurchase agreements.  In a reverse repurchase agreement, the Portfolio
sells a security and agrees to repurchase it at a mutually  agreed upon date and
price. For a discussion of reverse repurchase  agreements and the risks involved
therein,  see  this  Prospectus  under  "Certain  Risk  Factors  and  Investment
Methods."

         When-Issued,  Delayed Delivery and Forward Transactions.  The Portfolio
may purchase  securities  on a  when-issued  or delayed  delivery  basis,  which
generally  involves the purchase of a security  with payment and delivery due at
some time in the future. The Portfolio does not earn interest on such securities
until  settlement  and bears the risk of market value  fluctuations  between the
purchase and  settlement  dates.  For an additional  discussion  of  when-issued
securities  and  certain  risks  involved  therein,  see the  Trust's  SAI under
"Certain Risk Factors and Investment Methods."

         Illiquid Securities.  Subject to guidelines promulgated by the Board of
Trustees of the Trust, the Portfolio may also invest up to 15% of its net assets
in securities that are considered  illiquid  because of the absence of a readily
available  market  or due  to  legal  or  contractual  restrictions.  Securities
eligible  for  resale  under  Rule  144A  of the  Securities  Act of  1933,  and
commercial  paper issued under Section 4(2) of the Securities Act of 1933, could
be deemed "liquid" when saleable in a readily available market. For a discussion
of illiquid securities and the risks involved therein, see this Prospectus under
"Certain Risk Factors and Investment Methods."

         Lower-Rated  High-Yield Bonds. The Portfolio may invest no more than 5%
of its net assets (at the time of investment) in lower-rated  high-yield  bonds.
For a discussion of these instruments and the risks involved  therein,  see this
Prospectus  and the  Trust's SAI under  "Certain  Risk  Factors  and  Investment
Methods."

         Borrowing.  Subject to the Portfolio's  restrictions on borrowing,  the
Portfolio may also borrow money from banks.  For a discussion of the Portfolio's
limitations  on borrowing  and certain  risks  involved in  borrowing,  see this
Prospectus  under "Certain Risk Factors and Investment  Methods" and the Trust's
SAI under "Investment Objectives and Policies."

     Securities Lending. The Portfolio may lend its portfolio securities.  For a
discussion of the limits on and risks of lending securities, see this Prospectus
under "Certain Risk Factors and Investment Methods."

         Portfolio  Turnover.  Because  investment  changes usually will be made
without  reference to the length of time a security has been held, a significant
number of short-term transactions may result. To a limited extent, the Portfolio
may also purchase individual securities in anticipation of relatively short-term
price gains, and the rate of portfolio turnover will not be a determining factor
in the sale of such securities.  For a discussion of portfolio  turnover and its
effects, see this Prospectus and the Trust's SAI under "Portfolio Turnover."

AST Janus Small-Cap Growth Portfolio:

Investment  Objective:  The  investment  objective  of the  Portfolio is capital
appreciation. The Portfolio pursues its objective by normally investing at least
65% of its total assets in securities issued by small-sized companies.

Investment Policies:

         The  Portfolio  invests  primarily in common stocks with an emphasis on
securities of small-sized  companies.  Small-sized companies are those that have
market  capitalizations  of less than $1.5 billion or annual  gross  revenues of
less than $500 billion.  Companies whose capitalization or revenues fall outside
these ranges after the Portfolio's  initial  purchase  continue to be considered
small-sized  for the purposes of this policy.  The  Portfolio may also invest in
stocks of larger companies with potential for capital appreciation.

         The  Portfolio  will invest  substantially  all of its assets in common
stocks  to  the  extent  the  Sub-advisor  believes  that  the  relevant  market
environment  favors profitable  investing in those  securities.  The Sub-advisor
generally  takes a "bottom  up"  approach to building  the  Portfolio.  In other
words, it seeks to identify individual  companies with earnings growth potential
that may not be recognized by the market at large. Although themes may emerge in
the Portfolio,  securities are generally  selected without regard to any defined
industry sector or other similarly defined selection  procedure.  Realization of
income is not a significant investment consideration.

         Because  the  Portfolio  invests   primarily  in  common  stocks,   the
fundamental  risk of investing in the  Portfolio is that the value of the stocks
it  holds  might  decrease.  Stock  values  may  fluctuate  in  response  to the
activities of an individual company or in response to general market or economic
conditions.  Historically, common stocks have provided greater long-term returns
and have entailed greater  short-term risks than other  investments.  Smaller or
newer issuers,  such as those in which the Portfolio invests, are more likely to
realize more substantial  growth as well as suffer more significant  losses than
larger or more  established  issuers.  Investments in such companies can be both
more volatile and more speculative.

         The  Portfolio is designed  for  long-term  investors  who seek capital
appreciation  and who can tolerate the greater risks associated with investments
in foreign and  domestic  common  stocks.  The  Portfolio  is not  designed as a
short-term  trading  vehicle  and  should  not be  relied  upon  for  short-term
financial needs.

         The  Sub-advisor  tries to  reduce  the risk of the  Portfolio  through
diversification  of the  Portfolio's  assets,  so that the  effect of any single
holding on its overall  portfolio value is reduced.  In addition,  the Portfolio
will not  invest  25% or more of its  total  assets in any  particular  industry
(excluding U.S.  government  securities).  As described below, the Portfolio may
use futures,  options and other derivative  instruments to protect its portfolio
from movements in securities  prices and interest rates. The Portfolio may use a
variety of currency hedging techniques, including forward currency contracts, to
manage exchange rate risk.

         The Portfolio may invest in "special  situations"  from time to time. A
special situation arises when, in the opinion of the Sub-advisor, the securities
of a  particular  issuer will be  recognized  and  appreciate  in value due to a
specific  development  with  respect  to that  issuer.  Developments  creating a
special situation may include significant  changes in a company's  allocation of
its existing  capital,  a restructuring of assets,  a new product or process,  a
technological breakthrough, a management change or other extraordinary corporate
event,  or  differences  in  market  supply  of and  demand  for  the  security.
Investment in special  situations  may carry an  additional  risk of loss in the
event that the  anticipated  development  does not occur or does not attract the
expected attention.

         The  Portfolio  may  invest to a lesser  degree in types of  securities
other than common stocks,  including  preferred  stocks,  warrants,  convertible
securities and debt securities. The Portfolio may invest up to 25% of its assets
in mortgage- and asset-backed securities.  The Portfolio may invest up to 10% of
its assets in zero coupon,  pay-in-kind  and step coupon  securities,  which are
securities  that do not, or may not under  certain  circumstances,  make regular
interest payments.  The Portfolio may invest in  indexed/structured  securities,
which typically are short- to  intermediate-term  debt securities whose value at
maturity  or  interest  rate is linked to  currencies,  interest  rates,  equity
securities,  indices,  commodity  prices  or other  financial  indicators.  Such
securities may offer growth potential because of anticipated changes in interest
rates,  credit  standing,  currency  relationships  or other  factors.  For more
information  on certain of the other types of  securities in which the Portfolio
may invest,  see this  Prospectus  under  "Certain  Risk Factors and  Investment
Methods."

         When the Sub-advisor  believes that market conditions are not favorable
for  profitable  investing or when it is otherwise  unable to locate  investment
opportunities  with  favorable  risk/reward  characteristics,   the  Portfolio's
investments  may be  hedged  to a  greater  degree  and/or  its cash or  similar
investments  may increase.  In other words,  the Portfolio  does not always stay
fully invested in stocks and bonds. The assets that remain after the Sub-advisor
has committed available assets to desirable investment opportunities are kept in
cash or similar investments,  such as high-grade commercial paper,  certificates
of  deposit,   repurchase  agreements  or  other  short-term  debt  obligations,
including money market funds managed by the  Sub-advisor.  When the Portfolio is
hedged  or its cash  position  increases,  it might  not  participate  in market
advances  or  declines  to the  extent  that it would if it was not hedged or it
remained more fully invested in common stocks.

         Investing in Smaller  Companies.  The Portfolio may invest in companies
that have relatively small revenues,  have a small share of the market for their
products or services, or have limited geographic or product markets.  Smaller or
newer  companies  may lack depth of  management,  they may be unable to generate
funds  necessary for growth or potential  development  internally or to generate
such  funds  through  external  financing  on  favorable  terms,  or they may be
developing  or marketing  new products or services for which markets are not yet
established and may never become established. In addition, such companies may be
or become subject to intense competition from larger competitors.  Securities of
small companies held by the Portfolio may have more limited trading markets than
the markets for  securities of larger or more  established  issuers,  and may be
subject to wider price fluctuations.

         The Portfolio measures the size of a company in part through its market
capitalization.  Market  capitalization is the most commonly used measure of the
size and value of a company.  It is computed by  multiplying  the current market
price of a share  of the  company's  stock by the  total  number  of its  shares
outstanding.

         Foreign  Securities.  The Portfolio may invest without limit in foreign
equity  and debt  securities.  The  Portfolio  may  invest  directly  in foreign
securities  denominated  in foreign  currencies  and not publicly  traded in the
United States.  Other ways of investing in foreign securities include depositary
receipts or shares, and passive foreign  investment  companies.  Generally,  the
same criteria are used to select foreign securities as domestic securities.  The
Sub-advisor  seeks  companies  that meet its  selection  criteria  regardless of
country  of  organization  or  place of  principal  business  activity.  Foreign
securities are generally  selected on a  stock-by-stock  basis without regard to
any defined allocation among countries or geographic regions.  However,  certain
factors such as expected levels of inflation,  government  policies  influencing
business conditions,  the outlook for currency relationships,  and prospects for
economic growth among countries, regions or geographic areas may warrant greater
consideration in selecting foreign securities.

         Investments  in  foreign   securities,   including   those  of  foreign
governments,  may involve  greater risks than  investing in comparable  domestic
securities. The Portfolio may invest in emerging market or developing countries.
Emerging market  countries  involve  greater risks than other foreign  countries
such as immature economic structures,  national policies restricting investments
by foreigners,  and different  legal systems.  As long as the Portfolio  holds a
foreign security,  its value will be affected by the value of the local currency
relative  to the  U.S.  dollar.  When the  Portfolio  sells a  foreign  currency
denominated  security,  its value may be worth less in U.S.  dollars even though
the security  increases in value in its home country.  U.S.  dollar  denominated
securities of foreign issuers (e.g., depositary receipts) are subject to many of
the same risks as other foreign  securities,  including  currency risk,  because
their values depend on the performance of a foreign security  denominated in its
home currency. The risks of foreign investing,  including currency risks and the
risks of investing in developing countries, are described in more detail in this
Prospectus  and the  Trust's SAI under  "Certain  Risk  Factors  and  Investment
Methods."

         Portfolio  Turnover.   The  Portfolio  generally  intends  to  purchase
securities  for long-term  investment  rather than  short-term  gains.  However,
short-term  transactions  may result from  liquidity  needs,  securities  having
reached a price or yield  objective,  changes  in  interest  rates or the credit
standing  of an  issuer,  or by reason of  economic  or other  developments  not
foreseen  at the  time  of the  investment  decision.  Changes  are  made in the
Portfolio's  investments  whenever  the  Sub-advisor  believes  such changes are
desirable. Portfolio turnover rates are generally not a factor in making buy and
sell decisions.

         To  a  limited  extent,  the  Portfolio  may  purchase   securities  in
anticipation of relatively  short-term  price gains. The Portfolio may also sell
one security and  simultaneously  purchase the same or a comparable  security to
take advantage of short-term  differentials in bond yields or securities prices.
For a discussion of portfolio turnover and its effects,  see this Prospectus and
the Trust's SAI under "Portfolio Turnover."

         Illiquid  Investments.  The  Portfolio  may invest up to 15% of its net
assets in illiquid investments.  If illiquid securities exceed 15% of net assets
after  the time of  purchase,  the  Portfolio  will  take  steps to reduce in an
orderly fashion its holdings of illiquid securities. An illiquid investment is a
security  or other  position  that  cannot be  disposed of quickly in the normal
course of business because of the absence of a readily  available market for the
security, because of the terms of the security or because of legal restrictions.
The  Sub-advisor  will follow  guidelines  established  by the Trust's  Board of
Trustees in making  liquidity  determinations  for certain types of  securities,
including Rule 144A securities and privately placed  commercial paper. Rule 144A
securities are securities that are not registered for sale to the general public
under  the   Securities  Act  of  1933,  but  that  may  be  resold  to  certain
institutional investors.

     Borrowing and Lending.  The Portfolio may borrow money and lend  securities
in accordance with the restrictions  described below under "Certain Risk Factors
and Investment Methods."

         Futures,  Options and Other Derivative  Instruments.  The Portfolio may
enter into  futures  contracts  on  securities,  financial  indices  and foreign
currencies  and  options  on  such  contracts,  and may  invest  in  options  on
securities,  financial  indices and foreign  currencies,  forward  contracts and
interest  rate  swaps  and  swap-related  products   (collectively   "derivative
instruments").   The  Portfolio  intends  to  use  most  derivative  instruments
primarily  to  hedge  the  value  of its  portfolio  against  potential  adverse
movements in securities prices, foreign currency markets or interest rates. To a
limited  extent,   the  Portfolio  may  also  use  derivative   instruments  for
non-hedging  purposes  such as seeking to  increase  the  Portfolio's  income or
otherwise  seeking to enhance  return.  For a more detailed  discussion of these
instruments and their risks, see this Prospectus under "Certain Risk Factors and
Investment  Methods"  and the  Trust's  SAI  under  "Investment  Objectives  and
Policies and "Certain Risk Factors and Investment Methods."

         Although the  Sub-advisor  believes the use of  derivative  instruments
will benefit the Portfolio,  the Portfolio's  performance could be worse than if
the Portfolio had not used such instruments if the Sub-advisor's judgment proves
incorrect.

         High-Yield/High-Risk  Securities. The Portfolio may invest up to 35% of
its assets in high-yield/high-risk  securities.  High-yield/high-risk securities
(or "junk"  bonds)  are debt  securities  rated  below  investment  grade by the
primary rating agencies such as Standard & Poor's Ratings Services  ("Standard &
Poor's") and Moody's Investors Service, Inc. ("Moody's").

         Investments  in  high-yield   securities  are  considered  to  be  more
speculative  than  higher  quality  investments.  The  value  of  lower  quality
securities  generally  is more  dependent  on the ability of the company to meet
interest and principal payments (i.e.,  credit risk) than is the case for higher
quality  securities.  In addition,  issuers of  high-yield  securities  are more
vulnerable  to real or perceived  economic  changes (for  instance,  an economic
downturn or prolonged period of rising interest rates),  and political  changes.
For an additional  discussion of high-yield securities and their risks, see this
Prospectus  and the  Trust's SAI under  "Certain  Risk  Factors  and  Investment
Methods." Please refer to the SAI for a description of bond rating categories.

         When-Issued,  Delayed Delivery and Forward Commitment Transactions. The
Portfolio may purchase securities on a when-issued,  delayed delivery or forward
commitment  basis.  These  transactions  typically  involve  the  purchase  of a
security with payment and delivery at some time in the future (i.e.,  beyond the
normal settlement  period).  The Portfolio earns no interest on such securities,
but bears the risk of fluctuations  in their market value,  between the purchase
and settlement dates.

         Short Sales. The Fund may engage in "short sales against the box." This
technique  involves  selling  either a security  that the  Portfolio  owns, or a
security that the Portfolio has the right to obtain without additional cost, for
delivery at a specified date in the future. The Portfolio may enter into a short
sale against the box to hedge against  anticipated  declines in the market price
of portfolio  securities.  If the value of the securities  sold short  increases
prior to the scheduled  delivery  date, the Portfolio  loses the  opportunity to
participate in the gain.

AST T. Rowe Price International Equity Portfolio:

Investment  Objective:  The  investment  objective of the Portfolio is to seek a
total  return on its  assets  from  long-term  growth  of  capital  and  income,
principally  through  investments  in  common  stocks of  established,  non-U.S.
companies. Investments may be made solely for capital appreciation or solely for
income or any  combination of both for the purpose of achieving a higher overall
return. Total return consists of capital appreciation or depreciation,  dividend
income,  and currency  gains or losses.  This is a fundamental  objective of the
Portfolio.

Investment Policies:

         The Portfolio intends to diversify  investments broadly among countries
and to  normally  have at least three  different  countries  represented  in the
Portfolio.  The  Portfolio  may invest in  countries of the Far East and Western
Europe as well as South  Africa,  Australia,  Canada and other areas  (including
developing  countries).  Under unusual  circumstances,  the Portfolio may invest
substantially all of its assets in one or two countries.

         In seeking its objective, the Portfolio will invest primarily in common
stocks of established  foreign  companies which have the potential for growth of
capital or income or both.  However,  the Portfolio may also invest in a variety
of other  equity-related  securities,  such as  preferred  stocks,  warrants and
convertible  securities,  as well as corporate and governmental debt securities,
when  considered  consistent  with the  Portfolio's  investment  objectives  and
program.   Under  normal  market  conditions,   the  Portfolio's  investment  in
securities  other  than  common  stocks is  limited to no more than 35% of total
assets.  Under exceptional  economic or market conditions  abroad, the Portfolio
may temporarily  invest all or a major portion of its assets in U.S.  government
obligations  or debt  obligations  of U.S.  companies.  The  Portfolio  will not
purchase  any  debt  security  which  at the time of  purchase  is  rated  below
investment grade. This would not prevent the Portfolio from retaining a security
downgraded to below investment grade after purchase.

         The  Portfolio  may also  invest its  reserves  in  domestic as well as
foreign  money market  instruments.  Also,  the Portfolio may enter into forward
foreign currency exchange  contracts in order to protect against  uncertainty in
the level of future foreign exchange rates.

         In  addition  to  the  investments  described  below,  the  Portfolio's
investments may include,  but are not limited to, American  Depositary  Receipts
(ADRs),  bonds,  notes,  other  debt  securities  of  foreign  issuers,  and the
securities of foreign  investment  funds or trusts  (including  passive  foreign
investment companies).

         Cash Reserves.  While the Portfolio will remain  primarily  invested in
common stocks, it may, for temporary defensive measures, invest in cash reserves
without  limitation.  The  Portfolio  may  establish  and  maintain  reserves as
Sub-advisor  believes is advisable to facilitate the Portfolio's cash flow needs
(e.g.,  redemptions,  expenses and  purchases of  portfolio  securities)  or for
temporary,  defensive  purposes.  The  Portfolio's  reserves  may be invested in
domestic and foreign  money market  instruments  rated within the top two credit
categories  by a national  rating  organization,  or if unrated,  of  equivalent
investment quality as determined by the Sub-advisor.

         Convertible  Securities,  Preferred Stocks, and Warrants. The Portfolio
may  invest  in  debt  or  preferred  equity  securities   convertible  into  or
exchangeable  for  equity  securities.  Preferred  stocks  are  securities  that
represent an ownership interest in a corporation providing the owner with claims
on the company's  earnings and assets before common stock owners, but after bond
owners. Warrants are options to buy a stated number of shares of common stock at
a specified  price any time during the life of the warrants  (generally,  two or
more years).

         Foreign Currency Transactions.  The Portfolio will normally conduct its
foreign currency exchange  transactions  either on a spot (i.e.,  cash) basis at
the spot rate prevailing in the foreign  currency  exchange  market,  or through
entering  into forward  contracts to purchase or sell  foreign  currencies.  The
Portfolio  will  generally  not  enter  into a forward  contract  with a term of
greater than one year.

         The  Portfolio  will  generally  enter into  forward  foreign  currency
exchange  contracts  only under two  circumstances.  First,  when the  Portfolio
enters into a contract for the purchase or sale of a security  denominated  in a
foreign  currency,  it may  desire  to "lock  in" the U.S.  dollar  price of the
security.  Second,  when  the  Sub-advisor  believes  that  the  currency  of  a
particular  foreign country may suffer or enjoy a substantial  movement  against
another currency, it may enter into a forward contract to sell or buy the former
foreign  currency (or another  currency which acts as a proxy for that currency)
approximating the value of some or all of the Portfolio's securities denominated
in such foreign currency. Under certain circumstances,  the Portfolio may commit
a substantial  portion or the entire value of its portfolio to the  consummation
of these  contracts.  The Sub-advisor will consider the effect such a commitment
of its portfolio to forward  contracts  would have on the investment  program of
the  Portfolio  and the  flexibility  of the  Portfolio  to purchase  additional
securities.  For a  discussion  of  foreign  currency  contracts  and the  risks
involved  therein,  see this  Prospectus and the Trust's SAI under "Certain Risk
Factors and Investment Methods."

         Futures Contracts and Options. The Portfolio may enter into stock index
or currency  futures  contracts  (or options  thereon) to hedge a portion of the
Portfolio,  to provide an efficient means of regulating the Portfolio's exposure
to the equity  markets,  or as a hedge against  changes in prevailing  levels of
currency  exchange  rates.  The  Portfolio  will not use futures  contracts  for
leveraging purposes.  Such contracts may be traded on U.S. or foreign exchanges.
The  Portfolio  may write covered call options and purchase put and call options
on foreign currencies, securities, and stock indices. The aggregate market value
of the  Portfolio's  currencies  or portfolio  securities  covering  call or put
options will not exceed 25% of the Portfolio's total assets.  The Portfolio will
not commit more than 5% of its total assets to premiums when  purchasing call or
put options.  For an additional  discussion of futures contracts and options and
the risks  involved  therein,  see this  Prospectus  and the  Trust's  SAI under
"Certain  Risk  Factors  and  Investment  Methods"  and the  Trust's  SAI  under
"Investment Objectives and Policies."

         Hybrid  Investments.  The  Portfolio  may invest up to 10% of its total
assets in hybrid instruments.  As part of its investment program and to maintain
greater flexibility,  the Portfolio may invest in these instruments,  which have
the  characteristics  of futures,  options and securities.  Such instruments may
take a variety of forms,  such as debt  instruments  with  interest or principal
payments  determined by reference to the value of a currency,  security index or
commodity at a future point in time. The risks of such investments would reflect
both the risks of investing in futures,  options,  currencies,  and  securities,
including volatility and illiquidity.  Under certain conditions,  the redemption
value  of a  hybrid  instrument  could  be  zero.  For a  discussion  of  hybrid
investments  and  the  risks  involved  therein,   see  the  Trust's  SAI  under
"Investment  Objectives  and Policies" and "Certain Risk Factors and  Investment
Methods."

         Passive Foreign  Investment  Companies.  The Portfolio may purchase the
securities of certain foreign  investment funds or trusts called passive foreign
investment companies. Such trusts have been the only or primary way to invest in
certain  countries.  In addition  to bearing  their  proportionate  share of the
Portfolio's expenses (management fees and operating expenses), shareholders will
also indirectly bear similar expenses of such trusts.

         Illiquid Securities.  Subject to guidelines promulgated by the Board of
Trustees of the Trust,  the Portfolio may acquire  illiquid  securities (no more
than 15% of net  assets).  The  Portfolio  will not invest  more than 10% of its
total assets in restricted securities (other than securities eligible for resale
under Rule 144A of the Securities Act of 1933). For a discussion of illiquid and
restricted  securities and the risks involved therein, see this Prospectus under
"Certain  Risk  Factors  and  Investment  Methods"  and the  Trust's  SAI  under
"Investment Objectives and Policies."

         Repurchase  Agreements.  Subject to guidelines promulgated by the Board
of Trustees of the Trust,  the  Portfolio may enter into  repurchase  agreements
with a  well-established  securities  dealer or a bank  which is a member of the
Federal  Reserve System.  For a discussion of repurchase  agreements and certain
risks  involved  therein,  see this  Prospectus  under "Certain Risk Factors and
Investment  Methods"  and the  Trust's  SAI  under  "Investment  Objectives  and
Policies."

     Borrowing. For a discussion of the Portfolio's limitations on borrowing and
certain risks  involved in borrowing,  see this  Prospectus  under "Certain Risk
Factors  and  Investment   Methods"  and  the  Trust's  SAI  under   "Investment
Restrictions."

AST T. Rowe Price International Bond Portfolio:

Investment  Objective:  The investment  objective of the Portfolio is to provide
high current income and capital  appreciation by investing in high-quality,  non
dollar-denominated  government  and corporate  bonds outside the United  States.
This is a fundamental objective of the Portfolio.

         Special Risk  Considerations.  The  Portfolio is intended for long-term
investors who can accept the risks  associated  with investing in  international
bonds.  Total  return  consists of income after  expenses,  bond price gains (or
losses) in terms of the local currency and currency gains (or losses). The value
of the Portfolio will  fluctuate in response to various  economic  factors,  the
most important of which are fluctuations in foreign currency  exchange rates and
interest rates.

         Because  the  Portfolio's  investments  are  primarily  denominated  in
foreign  currencies,  exchange rates are likely to have a significant  impact on
total  Portfolio  performance.  For example,  a fall in the U.S.  dollar's value
relative to the Japanese yen will  increase the U.S.  dollar value of a Japanese
bond  held in the  Portfolio,  even  though  the price of that bond in yen terms
remains unchanged. Conversely, if the U.S. dollar rises in value relative to the
yen, the U.S.  dollar value of a Japanese  bond will fall.  Investors  should be
aware  that  exchange  rate  movements  can be  significant  and endure for long
periods of time.

         The  Sub-advisor's  techniques  include  management  of currency,  bond
market and maturity  exposure and  security  selection  which will vary based on
available  yields and the  Sub-advisor's  outlook for the interest rate cycle in
various  countries and changes in foreign currency exchange rates. In any of the
markets in which the Portfolio invests,  longer maturity bonds tend to fluctuate
more in price as interest  rates change than  shorter-term  instruments -- again
providing both opportunity and risk.

         Because of the Portfolio's long-term investment  objectives,  investors
should not rely on an investment in the Portfolio for their short-term financial
needs and should not view the  Portfolio  as a vehicle  for  playing  short-term
swings in the  international  bond and foreign exchange  markets.  Shares of the
Portfolio alone should not be regarded as a complete investment  program.  Also,
investors  should be aware that investing in  international  bonds may involve a
higher degree of risk than investing in U.S. bonds.

         Investments in foreign securities involve special considerations. For a
discussion of the risks  involved in investing in foreign  securities,  see this
Prospectus  and the  Trust's SAI under  "Certain  Risk  Factors  and  Investment
Methods."

Investment Policies:

         To achieve its  objectives,  the Portfolio  will invest at least 65% of
its assets in  high-quality,  non  dollar-denominated  government  and corporate
bonds  outside the United  States.  The Portfolio  also seeks to moderate  price
fluctuation by actively managing its maturity  structure and currency  exposure.
The Sub-advisor  bases its investment  decisions on fundamental  market factors,
currency  trends,  and  credit  quality.  The  Portfolio  generally  invests  in
countries where the combination of  fixed-income  returns and currency  exchange
rates appears  attractive,  or, if the currency trend is unfavorable,  where the
currency risk can be minimized through hedging.

         Although  the  Portfolio  expects to maintain an  intermediate  to long
weighted  average  maturity,  it has no  maturity  restrictions  on the  overall
portfolio or on individual  securities.  Normally,  the Portfolio does not hedge
its foreign currency  exposure back to the dollar,  nor involve more than 50% of
total  assets in cross  hedging  transactions.  Therefore,  changes  in  foreign
interest  rates and  currency  exchange  rates are likely to have a  significant
impact on total  return  and the  market  value of  portfolio  securities.  Such
changes  provide  greater  opportunities  for capital gains and greater risks of
capital  loss.   The   Sub-advisor   attempts  to  reduce  these  risks  through
diversification among foreign securities and active management of maturities and
currency exposures.

         The  Portfolio  may  also  invest  up to  20% of its  assets  in  below
investment-grade,  high-risk bonds, including bonds in default or those with the
lowest rating. Defaulted bonds are acquired only if the Sub-advisor foresees the
potential  for  significant   capital   appreciation.   Securities  rated  below
investment-grade  are commonly  referred to as "junk bonds" and involve  greater
price  volatility and higher degrees of speculation  with respect to the payment
of principal  and interest  than higher  quality  fixed-income  securities.  The
market prices of such lower-rated  debt securities may decline  significantly in
periods of general  economic  difficulty.  In addition,  the trading  market for
these  securities is generally less liquid than for higher rated  securities and
the Portfolio may have difficulty  disposing of these  securities at the time it
wishes to do so. The lack of a liquid  secondary  market for certain  securities
may also make it more  difficult  for the  Portfolio to obtain  accurate  market
quotations for purposes of valuing its portfolio and  calculating  its net asset
value.  For a discussion of the risks involved in lower-rated  debt  securities,
see this  Prospectus  and the  Trust's  SAI  under  "Certain  Risk  Factors  and
Investment Methods."

         The Portfolio's investments may also include: debt securities issued or
guaranteed by a foreign national government, its agencies,  instrumentalities or
political  subdivisions;  debt securities  issued or guaranteed by supranational
organizations (e.g., European Investment Bank, InterAmerican Development Bank or
the World Bank);  bank or bank holding company debt securities;  debt securities
convertible into common stock.

         The  Portfolio may invest in zero coupon  securities  which pay no cash
income and are sold at substantial discounts from their value at maturity.  When
held to maturity,  their entire income, which consists of accretion of discount,
comes from the  difference  between the issue price and their value at maturity.
Zero coupon  securities  are subject to greater market value  fluctuations  from
changing  interest rates than debt  obligations of comparable  maturities  which
make current cash  distribution  of  interest.  For a discussion  of zero coupon
securities,  see the  Trust's SAI under  "Certain  Risk  Factors and  Investment
Methods."

         The Portfolio may purchase  securities which are not publicly  offered.
If such securities are purchased, they may be subject to restrictions applicable
to restricted  securities.  The Portfolio may invest up to 15% of its net assets
in illiquid securities. For a discussion of the risks involved with illiquid and
restricted  securities,  see this  Prospectus  under  "Certain  Risk Factors and
Investment Methods."

         The  Portfolio  intends  to  select  its  investments  from a number of
country and market sectors. It may substantially invest in the issuers in one or
more  countries and intends to have  investments in securities of issuers from a
minimum of three  different  countries.  For  temporary  defensive  or emergency
purposes,  however,  the  Portfolio  may  invest  without  limit  in  U.S.  debt
securities,  including  short-term money market securities.  It is impossible to
predict for how long such alternative strategies will be utilized.

         Short-Term  Investments.   To  protect  against  adverse  movements  of
interest  rates and for  liquidity,  the Portfolio may also purchase  short-term
obligations  denominated in U.S. and foreign currencies (including the ECU) such
as, but not limited to, bank deposits,  bankers'  acceptances,  certificates  of
deposit,   commercial   paper,   short-term   government,   government   agency,
supranational agency and corporate obligations, and repurchase agreements.

         Nondiversified  Investment Company.  The Portfolio may invest more than
5%  of  its  assets  in  the  fixed-income   securities  of  individual  foreign
governments.  The Portfolio generally will not invest more than 5% of its assets
in any individual  corporate  issuer,  provided that (1) the Portfolio may place
assets in bank deposits or other  short-term bank instruments with a maturity of
up to 30 days provided  that (i) the bank has a short-term  credit rating of A1+
(or, if unrated,  the equivalent as determined by the  Sub-advisor) and (ii) the
Portfolio  may not  maintain  more than 10% of its total  assets with any single
bank;  and (2) the  Portfolio  may  maintain  more than 5% of its total  assets,
including cash and currencies,  in custodial accounts or deposits of the Trust's
custodian or sub-custodians.  In addition, the Portfolio intends to qualify as a
regulated  investment  company for purposes of the Internal  Revenue Code.  Such
qualification  requires the Portfolio to limit its  investments  so that, at the
end of each calendar quarter,  with respect to at least 50% of its total assets,
not more than 5% of such  assets  are  invested  in the  securities  of a single
issuer, and with respect to the remaining 50%, no more than 25% is invested in a
single issuer.  Since, as a nondiversified  investment company, the Portfolio is
permitted to invest a greater  proportion  of its assets in the  securities of a
smaller  number of issuers,  the Portfolio may be subject to greater credit risk
with respect to its portfolio securities than an investment company that is more
broadly diversified.

         Brady Bonds.  The  Portfolio  may invest in Brady  Bonds.  Brady bonds,
named after former U.S.  Secretary of the Treasury Nicholas Brady, are used as a
means of  restructuring  the  external  debt burden of a  government  in certain
emerging  markets.  A Brady bond is created when an outstanding  commercial bank
loan to a government or private entity is exchanged for a new bond in connection
with  a  debt   restructuring   plan.  Brady  bonds  may  be  collateralized  or
uncollateralized  and issued in various  currencies  (although  typically in the
U.S.  dollar).  They are often  fully  collateralized  as to  principal  in U.S.
Treasury zero coupon bonds. However, even with this  collateralization  feature,
Brady Bonds are often considered speculative, below investment grade investments
because  the timely  payment of interest  is the  responsibility  of the issuing
party (for  example,  a Latin  American  country) and the value of the bonds can
fluctuate  significantly  based on the issuer's ability or perceived  ability to
make these payments.  Finally,  some Brady Bonds may be structured with floating
rate or low fixed rate coupons.  The Portfolio does not expect to have more than
10% of its total assets invested in Brady Bonds.

         Repurchase  Agreements.  Subject to guidelines promulgated by the Board
of Trustees of the Trust,  the  Portfolio may enter into  repurchase  agreements
with  well-established  securities  dealers  or a bank  that is a member  of the
Federal Reserve System. For a discussion of repurchase  agreements and the risks
involved therein, see this Prospectus under "Certain Risk Factors and Investment
Methods."

         When-Issued or Delayed Delivery Securities.  The Portfolio may purchase
securities on a when-issued or forward  delivery basis, for payment and delivery
at a later  date.  The  price  and  yield  are  generally  fixed  on the date of
commitment to purchase.  During the period between  purchase and settlement,  no
interest accrues to the Portfolio.  At the time of settlement,  the market value
of the security may be more or less than the purchase  price.  For an additional
discussion of when-issued  securities and the risks  involved  therein,  see the
Trust's SAI under "Certain Risk Factors and Investment Methods."

         Passive Foreign  Investment  Companies.  The Portfolio may purchase the
securities of certain foreign  investment funds or trusts called passive foreign
investment companies. Such trusts have been the only or primary way to invest in
certain  countries.  In addition  to bearing  their  proportionate  share of the
trusts' expenses (management fees and operating expenses) shareholders will also
indirectly bear similar expenses of such trusts.

         Hybrid  Instruments.  The  Portfolio  may invest up to 10% of its total
assets in hybrid instruments.  As part of its investment program and to maintain
greater flexibility,  the Portfolio may invest in these instruments,  which have
the  characteristics  of futures,  options and securities.  Such instruments may
take a variety of forms,  such as debt  instruments  with  interest or principal
payments determined by reference to the value of a currency, securities index or
commodity at a future point in time. The risks of such investments would reflect
both the risks of  investing  in  futures,  options  and  securities,  including
volatility and illiquidity.  Under certain conditions, the redemption value of a
hybrid  instrument could be zero. For a discussion of hybrid  securities and the
risks  involved  therein,  see the Trust's SAI under  "Certain  Risk Factors and
Investment Methods."

         Foreign  Currency  Transactions.  The  Portfolio  may engage in foreign
currency  transactions  either on a spot (cash) basis at the rate  prevailing in
the currency  exchange market at the time or through forward currency  contracts
("forwards")  with terms generally of less than one year.  Forwards will be used
primarily to adjust the foreign  exchange  exposure of the Portfolio with a view
to  protecting  the  Portfolio  from adverse  currency  movements,  based on the
Sub-advisor's  outlook,  and the Portfolio  might be expected to enter into such
contracts under the following circumstances:

     Lock In. When  management  desires to lock in the U.S.  dollar price on the
purchase or sale of a security denominated in a foreign currency.

                  Cross Hedge. If a particular  currency is expected to decrease
against  another  currency,  the  Portfolio  may sell the  currency  expected to
decrease  and  purchase a currency  which is expected  to  increase  against the
currency sold in an amount approximately equal to some or all of the Portfolio's
holdings denominated in the currency sold.

                  Proxy  Hedge.  The  Sub-advisor  might  choose  to use a proxy
hedge, where the Portfolio,  having purchased a bond, will sell a currency whose
value is  believed  to be closely  linked to the  currency  in which the bond is
denominated.  Interest  rates  prevailing in the country whose currency was sold
would be  expected  to be closer to those in the U.S.  and lower  than  those of
bonds denominated in the currency of the original holding.  This type of hedging
entails  greater  risk than a direct  hedge  because it is dependent on a stable
relationship  between the two currencies paired as proxies and the relationships
can be very unstable at times.

         For an additional discussion of foreign currency exchange contracts and
the risks  involved  therein,  see this  Prospectus  and the  Trust's  SAI under
"Certain Risk Factors and Investment Methods."

         Costs of Hedging.  When the  Portfolio  purchases a foreign bond with a
higher interest rate than is available on U.S. bonds of a similar maturity,  the
additional  yield  on the  foreign  bond  could  be  substantially  lost  if the
Portfolio were to enter into a direct hedge by selling the foreign  currency and
purchasing  the U.S.  dollar.  This is what is known as the  "cost" of  hedging.
Proxy hedging attempts to reduce this cost through an indirect hedge back to the
U.S.  dollar.  It is important to note that hedging costs are treated as capital
transactions  and are not,  therefore,  deducted from the  Portfolio's  dividend
distribution  and are not reflected in its yield.  Instead such costs will, over
time, be reflected in the Portfolio's net asset value per share.

         Futures and Options. The Portfolio may buy and sell futures and options
contracts  for any number of reasons  including:  to manage  their  exposure  to
changes in  interest  rates,  securities  prices and foreign  currencies;  as an
efficient means of adjusting  overall  exposure to certain  markets;  to enhance
income;  to  protect  the  value of  portfolio  securities;  and to  adjust  the
portfolio's  duration.  The Portfolio may purchase,  sell, or write call and put
options on securities,  financial  indices,  and foreign  currencies.  The total
market value of  securities  against which the Portfolio has written call or put
options may not exceed 25% of its total assets.  The  Portfolio  will not commit
more  than 5% of its  total  assets  to  premiums  when  purchasing  call or put
options.  For an additional  discussion of futures and options and certain risks
involved  therein,  see this  Prospectus and the Trust's SAI under "Certain Risk
Factors and Investment Methods."

     Borrowing.  For a  discussion  of  the  limitations  on  borrowing  by  the
Portfolio and certain risks involved therein, see this Prospectus under "Certain
Risk  Factors and  Investment  Methods"  and the  Trust's SAI under  "Investment
Restrictions."

     Portfolio  Turnover.  The Portfolio may have higher portfolio turnover than
other mutual  funds with  similar  investment  objectives.  For a discussion  of
portfolio  turnover and its  effects,  see this  Prospectus  and the Trust's SAI
under "Portfolio Turnover."

AST INVESCO Equity Income Portfolio:

Investment Objective:  The investment objective of the Portfolio is to seek high
current income while following sound investment practices. This is a fundamental
objective of the  Portfolio.  Capital  growth  potential is an  additional,  but
secondary, consideration in the selection of portfolio securities.

Investment Policies:

         The Portfolio seeks to achieve its objective by investing in securities
which will provide a relatively  high yield and stable return and which,  over a
period of years, may also provide capital  appreciation.  The Portfolio normally
will  invest at least 65% of its assets in  dividend-paying,  marketable  common
stocks of domestic and foreign issuers.  Up to 10% of the Portfolio's assets may
be  invested  in  equity  securities  that do not  pay  regular  dividends.  The
Portfolio  also will  invest in  convertible  bonds,  preferred  stocks and debt
securities.   In  periods  of  uncertain  market  and  economic  conditions,  as
determined  by the Board of Trustees,  the  Portfolio  may depart from the basic
investment  objective  and assume a  defensive  position  with up to 100% of its
assets  temporarily  invested  in high  quality  corporate  bonds,  or notes and
government issues, or held in cash.

         The Portfolio's investments in common stocks may, of course, decline in
value.  To minimize  the risk this  presents,  the  Sub-advisor  only invests in
common stocks and equity  securities  of domestic and foreign  issuers which are
marketable;  and will not invest more than 5% of the  Portfolio's  assets in the
securities of any one company or more than 25% of the Portfolio's  assets in any
one industry.

         Debt  Securities.  The Portfolio's  investments in debt securities will
generally be subject to both credit risk and market risk. Credit risk relates to
the ability of the issuer to meet  interest or principal  payments,  or both, as
they come due.  Market risk  relates to the fact that the market  values of debt
securities in which the Portfolio  invests generally will be affected by changes
in the level of interest  rates.  An  increase  in  interest  rates will tend to
reduce the market values of debt securities, whereas a decline in interest rates
will tend to increase  their  values.  Although the  Sub-advisor  will limit the
Portfolio's  debt security  investments to securities it believes are not highly
speculative,  both kinds of risk are  increased by investing in debt  securities
rated below the top four grades by Standard & Poor's  Corporation  ("Standard  &
Poor's) or  Moody's  Investors  Services,  Inc.  ("Moody's")  and  unrated  debt
securities,   other  than  Government  National  Mortgage  Association  modified
pass-through certificates.

         In order to decrease  its risk in  investing  in debt  securities,  the
Portfolio  will invest no more than 15% of its assets in debt  securities  rated
below AAA,  AA, A or BBB by Standard & Poor's,  or Aaa, Aa, A or Baa by Moody's,
and in no event will the Portfolio  ever invest in a debt  security  rated below
Caa by  Moody's  or CCC by  Standard  & Poor's.  Lower  rated  bonds by  Moody's
(categories  Ba,  B,  Caa)  are of  poorer  quality  and  may  have  speculative
characteristics.  Bonds  rated Caa may be in  default  or there  may be  present
elements of danger with respect to  principal or interest.  Lower rated bonds by
Standard & Poor's  (categories BB, B, CCC) include those which are regarded,  on
balance,  as predominantly  speculative with respect to the issuer's capacity to
pay interest and repay  principal in accordance  with their terms;  BB indicates
the lowest degree of  speculation  and CCC a high 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.  For a description  of securities  ratings,  see the Appendix to the
Trust's SAI.

         While the  Sub-advisor  will monitor all of the debt  securities in the
Portfolio  for the  issuers'  ability to make  required  principal  and interest
payments and other quality factors,  the Sub-advisor may retain in the Portfolio
a debt security whose rating is changed to one below the minimum rating required
for purchase of such a security.  For a discussion of the special risks involved
in  lower-rated  bonds,  see this  Prospectus and the Trust's SAI under "Certain
Risk Factors and Investment Methods."

         Portfolio Turnover.  There are no fixed limitations regarding portfolio
turnover. The rate of portfolio turnover may fluctuate as a result of constantly
changing  economic  conditions and market  circumstances.  Securities  initially
satisfying the Portfolio's basic objectives and policies may be disposed of when
they are no longer  suitable.  As a result,  the  Portfolio's  annual  portfolio
turnover  rate may be higher  than that of other  investment  companies  seeking
current  income  with  capital  growth  as  a  secondary  consideration.  For  a
discussion of portfolio  turnover and its effects,  see this  Prospectus and the
Trust's SAI under "Portfolio Turnover."

         Repurchase  Agreements.  Subject to guidelines promulgated by the Board
of Trustees of the Trust,  the  Portfolio may enter into  repurchase  agreements
with respect to debt instruments eligible for investment by the Portfolio. These
agreements  are entered  into with member banks of the Federal  Reserve  System,
registered  broker-dealers,  and registered  government securities dealers which
are deemed  creditworthy.  A repurchase agreement is a means of investing moneys
for a short period.  In a repurchase  agreement,  the Portfolio  acquires a debt
instrument  (generally  a security  issued by the U.S.  Government  or an agency
thereof, a banker's acceptance or a certificate of deposit) subject to resale to
the seller at an agreed upon price and date  (normally,  the next business day).
In the event that the original  seller  defaults on its obligation to repurchase
the security,  the Portfolio could incur costs or delays in seeking to sell such
security.  To minimize risk, the securities underlying each repurchase agreement
will be maintained with the Portfolio's custodian in an amount at least equal to
the repurchase price under the agreement (including accrued interest),  and such
agreements will be effected only with parties that meet certain creditworthiness
standards  established by the Trust's Board of Trustees.  The Portfolio will not
enter  into a  repurchase  agreement  maturing  in more than  seven days if as a
result  more than 15% of the  Portfolio's  net assets  would be invested in such
repurchase  agreements  and other  illiquid  securities.  The  Portfolio has not
adopted  any limit on the amount of its total  assets  that may be  invested  in
repurchase agreements maturing in seven days or less.

         Foreign  Securities.  The  Portfolio  may invest up to 25% of its total
assets in foreign securities. Investments in securities of foreign companies and
in  foreign  markets  involve  certain  additional  risks  not  associated  with
investments  in domestic  companies  and markets.  The  Portfolio  may invest in
countries  considered to be developing  which may involve  special risks.  For a
discussion  of these risks and the risks of investing in foreign  securities  in
general, see this Prospectus and the Trust's SAI under "Certain Risk Factors and
Investment Methods."

         Illiquid Securities.  Subject to guidelines promulgated by the Board of
Trustees of the Trust,  the  Portfolio may invest up to 15% of its net assets in
securities  that are illiquid by virtue of legal or contractual  restrictions on
resale or the absence of a readily available market.  The Board of Trustees,  or
the Investment Manager or the Sub-advisor acting pursuant to authority delegated
by the Board of Trustees,  may determine that a readily  available market exists
for  securities  eligible for resale  pursuant to Rule 144A under the Securities
Act of 1933, or any successor to that rule, and therefore  that such  securities
are not subject to the  foregoing  limitation.  For a discussion  of  restricted
securities and the risks involved  therein,  see this Prospectus  under "Certain
Risk Factors and Investment Methods."

     Borrowing. For a discussion of the Portfolio's limitations on borrowing and
certain risks  involved in borrowing,  see this  Prospectus  under "Certain Risk
Factors  and  Investment   Methods"  and  the  Trust's  SAI  under   "Investment
Restrictions."

AST Neuberger Berman Mid-Cap Value Portfolio:

     Investment Objective:  The investment objective of the Portfolio is to seek
capital growth.

Investment Policies:

         The Portfolio seeks capital growth through an investment  approach that
is designed to increase  capital with  reasonable  risk.  The Portfolio  invests
principally  in common  stocks of  medium  to large  capitalization  established
companies,  using  the  value-oriented  investment  approach.  A  value-oriented
portfolio  manager  buys  stocks  that are selling at a price that is lower than
what the  manager  believes  they  are  worth.  These  include  stocks  that are
currently under-researched or are temporarily out of favor on Wall Street.

         Portfolio  managers  identify  value stocks in several ways. One of the
most common  identifiers  is a low  price-to-earnings  ratio -- that is,  stocks
selling  at  multiples  of  earnings  per share  that are lower than that of the
market as a whole.  Other  criteria are high dividend  yield,  a strong  balance
sheet and financial position, a recent company  restructuring with the potential
to realize hidden values,  strong management,  and low price-to-book  value (net
value of the company's assets). The Sub-advisor looks for securities believed to
be undervalued based on strong fundamentals,  including a low  price-to-earnings
ratio, consistent cash flow, and the company's track record through all parts of
the market cycle.

         The  Sub-advisor   believes  that,  over  time,   securities  that  are
undervalued  are more likely to  appreciate in price and be subject to less risk
of price decline than securities  whose market prices have already reached their
perceived  economic value.  This approach also  contemplates  selling  portfolio
securities when they are considered to have reached their potential.

         The Sub-advisor  considers additional factors when selecting securities
for  the  Portfolio,  including  ownership  by a  company's  management  of  the
company's stock and the dominance of a company in its particular field.

         In  addition  to  investing  in the  stocks  of  medium  capitalization
companies ("mid-cap  companies") and large capitalization  companies ("large-cap
companies"),  investments  may be made in  smaller,  less  well-known  companies
("small-cap  companies").  Investments in small- and mid-cap  company stocks may
present  greater  opportunities  for capital  appreciation  than  investments in
stocks of large-cap  companies.  However,  small- and mid-cap company stocks may
have higher  risk and  volatility.  These  stocks  generally  are not as broadly
traded as large-cap  company  stocks and their prices may fluctuate  more widely
and  abruptly.  Any such  movements  in stocks  held by the  Portfolio  would be
reflected in the Portfolio's net asset value.  Small- and mid-cap company stocks
are also less researched than large-cap  company stocks and are often overlooked
in the market.

         An investment in the Portfolio  involves certain risks,  depending upon
the types of investments  it makes.  Although the Portfolio  ordinarily  invests
primarily  in common  stocks,  when market  conditions  warrant it may invest in
preferred stocks, securities convertible into or exchangeable for common stocks,
U.S.  Government  and  agency  securities,  debt  securities,  or  money  market
instruments, or may retain assets in cash or cash equivalents. The Portfolio may
not  necessarily  buy any or all of the types of securities or use any or all of
the  techniques  that are  described  below.  As discussed in more detail below,
special  risk  factors  apply  to  certain  investments  that may be made by the
Portfolio,  including investments in foreign securities, options contracts, zero
coupon bonds, and debt securities rated below investment grade. Up to 15% of the
Portfolio's net assets,  measured at the time of investment,  may be invested in
corporate  debt  securities  that are below  investment  grade or in  comparable
unrated securities.  The use of hedging or other techniques is discretionary and
no  representation is made that the risk of the Portfolio will be reduced by the
techniques discussed below.

         Short-Term Trading;  Portfolio Turnover. While the Sub-advisor does not
purchase securities with the intention of profiting from short-term trading, the
Portfolio may sell portfolio  securities when the Sub-advisor believes that such
action is advisable. Therefore, the Portfolio may have higher portfolio turnover
than other mutual funds with similar  objectives.  For a discussion of portfolio
turnover  and its  effects,  see  this  Prospectus  and the  Trust's  SAI  under
"Portfolio Turnover."


         Cash Investments.  For temporary defensive purposes,  the Portfolio may
invest up to 100% of its assets in cash or cash equivalents, U.S. Government and
agency securities,  commercial paper and certain other money market instruments,
as well as repurchase agreements  collateralized by the foregoing. To the extent
that the Portfolio is invested in these temporary defensive instruments, it will
not be pursuing its investment objective.

         Fixed Income  Securities.  The  Portfolio may invest in fixed income or
debt  securities,  the value of which are  likely to  decline in times of rising
interest  rates and rise in times of falling  interest  rates.  In general,  the
longer the  maturity of a fixed  income  security,  the more  pronounced  is the
effect of a change in interest rates on the value of the security.

         High quality debt securities are securities that have received a rating
from  at  least  one  nationally  recognized   statistical  rating  organization
("NRSRO"),  such as Standard & Poor's Rating Group  ("S&P"),  Moody's  Investors
Service,  Inc.  ("Moody's"),  Fitch Investors Services,  or Duff & Phelps Credit
Rating Co. 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 the Sub-advisor to be
of comparable  quality.  Investment  grade debt  securities are those  receiving
ratings from at least one NRSRO in one of the four highest rating categories or,
if unrated by any NRSRO,  deemed  comparable  by the  Sub-advisor  to such rated
securities. Securities rated by Moody's in its fourth highest category (Baa) may
have speculative  characteristics;  a change in economic factors could lead to a
weakened capacity of the issuer to repay.

         Lower-Rated  Fixed Income  Securities.  Debt securities rated below the
fourth  highest  category  by all NRSROs that have rated  them,  and  comparable
unrated  securities,  are considered to be below investment grade. The Portfolio
may invest up to 15% of its net assets,  measured at the time of investment,  in
debt  securities  that  are  below  investment   grade  or  comparable   unrated
securities. Securities rated below investment grade ("junk bonds") are judged to
be  predominantly  speculative  with  respect to the  issuer's  capacity  to pay
interest and repay  principal in accordance  with the terms of the  obligations.
While such  securities  may be  considered  predominantly  speculative,  as debt
securities,  they  generally  have priority  over equity  securities of the same
issuer and are generally better secured.

         Debt  securities  in  the  lowest  rating   categories  may  involve  a
substantial risk of default or may be in default. Changes in economic conditions
or developments  regarding the individual  issuer are more likely to cause price
volatility  and weaken the  capacity  of the issuer of such  securities  to make
principal  and  interest  payments  than  is  the  case  for  higher-grade  debt
securities. An economic downturn affecting the issuer may result in an increased
incidence of default. In the case of lower-rated  securities  structured as zero
coupon or pay-in-kind securities,  their market prices are affected to a greater
extent by interest  rate changes,  and  therefore  tend to be more volatile than
securities  that pay interest  periodically  and in cash. The  Sub-advisor  will
invest in such securities only when it concludes that the anticipated  return to
the Portfolio on such an investment warrants exposure to the additional level of
risk.

         For an  additional  discussion  of the risks  involved  in  lower-rated
bonds,  see this  Prospectus and the Trust's SAI under "Certain Risk Factors and
Investment  Methods." For an  additional  description  of the ratings  services'
securities ratings, see the Appendix the Trust's SAI.

         Convertible  Securities.   The  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. Many convertible  securities are
rated below investment grade, or are unrated.

         Zero Coupon  Securities.  Zero coupon  securities  do not pay  interest
currently;  instead,  they are sold at a discount  from their face value and are
redeemed at face value when they  mature.  Because  zero coupon bonds do not pay
current income, their prices can be very volatile when interest rates change.

     U.S.  Government  and Agency  Securities.  U.S.  Government  securities are
obligations  of the U.S.  Treasury  backed by the full  faith and  credit of the
United States.  U.S.  Government  agency  securities are issued or guaranteed by
U.S. Government agencies, instrumentalities,  or other U.S. Government-sponsored
enterprises,  such as the Government  National  Mortgage  Association  (commonly
known  as  "Ginnie  Mae"),   Fannie  Mae,  formerly  Federal  National  Mortgage
Association,  Freddie  Mac,  formerly  Federal Home Loan  Mortgage  Corporation,
Student  Loan  Marketing  Association  (commonly  known as  "Sallie  Mae"),  and
Tennessee Valley  Authority.  Agency  securities may be backed by the full faith
and credit of the United  States,  the issuer's  ability to borrow from the U.S.
Treasury,  subject to the Treasury's discretion in certain cases, or only by the
credit of the  issuer.  U.S.  Government  and  agency  securities  include  U.S.
Government  and agency  mortgage-backed  securities.  The market  prices of U.S.
Government  and agency  securities  are not  guaranteed  by the  government  and
generally fluctuate inversely with changing interest rates.

         Borrowings. As a non-fundamental policy, the Portfolio may not purchase
portfolio securities if its outstanding borrowings, including reverse repurchase
agreements, exceed 5% of its total assets. In addition, the Portfolio is subject
to the fundamental  restriction on borrowing  described in the Trust's SAI under
"Investment Restrictions."

         Illiquid,  Restricted and Rule 144A  Securities.  Subject to guidelines
established  by the Board of Trustees of the Trust,  the Portfolio may invest up
to 15% of its net  assets in  illiquid  securities,  which 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 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 the  Sub-advisor,  acting pursuant to
the guidelines established by the Board of Trustees, determines they are liquid.
Generally,  foreign securities freely tradable in their principal market are not
considered  restricted or illiquid.  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.

         Foreign Securities. The Portfolio may invest in U.S. dollar-denominated
foreign securities.  Foreign securities are those of issuers organized and doing
business  principally outside the U.S.,  including non-U.S.  governments,  their
agencies, and instrumentalities.  The Portfolio may invest in foreign securities
denominated in or indexed to foreign  currencies,  which may also be affected by
the  fluctuation  of  the  foreign  currencies  relative  to  the  U.S.  dollar,
irrespective  of the performance of the underlying  investment.  The Sub-advisor
considers these factors in making  investments for the Portfolio.  The Portfolio
may invest in U.S. dollar-denominated and non-U.S.  dollar-denominated corporate
and government debt securities of foreign  issuers.  In addition,  the Portfolio
may  enter  into  forward  foreign  currency   contracts  or  futures  contracts
(agreements  to exchange  one currency for another at a future date) and related
options  to manage  currency  risks and to  facilitate  transactions  in foreign
securities.

         The  Portfolio  may only  invest  up to 10% of the  value of its  total
assets,  measured  at the time of  investment,  in foreign  securities.  The 10%
limitation  does  not  apply  with  respect  to  foreign   securities  that  are
denominated in U.S. dollars.

     The Portfolio may invest in ADRs,  EDRs, GDRs, and IDRs. ADRs (sponsored or
unsponsored)  are  receipts  typically  issued by a U.S.  bank or trust  company
evidencing its ownership of the  underlying  foreign  securities.  Most ADRs are
denominated in U.S. dollars and are traded on a U.S. stock exchange.  Issuers of
the securities  underlying  unsponsored ADRs are not contractually  obligated to
disclose  material  information in the U.S. and,  therefore,  there may not be a
correlation  between such  information  and the market value of the  unsponsored
ADR.  EDRs and IDRs are receipts  typically  issued by a European  bank or trust
company evidencing its ownership of the underlying foreign securities.  GDRs are
receipts issued by either a U.S. or non-U.S.  banking institution evidencing its
ownership of the underlying foreign securities and are often denominated in U.S.
dollars.

         Investments  in  foreign   securities  could  be  affected  by  factors
generally  not thought to be present in the U.S. Such factors  include,  but are
not limited to, varying custody, brokerage and settlement practices;  difficulty
in pricing some foreign securities;  and potentially  adverse local,  political,
economic,  social, or diplomatic  developments,  the investment  significance of
which may be difficult to discern.

         In addition,  the risks of investing in securities of foreign companies
and governments include changes in currency exchange rates and currency exchange
control regulations or other foreign or U.S. laws or restrictions  applicable to
such  investments  or  devaluations  of  foreign  currencies.  A decline  in the
exchange   rate  would  reduce  the  value  of  certain   portfolio   securities
irrespective  of the  performance of the underlying  investment.  Investments in
depositary  receipts (whether or not denominated in U.S. dollars) may be subject
to  exchange  controls  and changes in rates of  exchange  with the U.S.  dollar
because the underlying security is usually denominated in foreign currency.  All
of the foregoing  risks may be intensified in emerging  industrialized  and less
developed countries.

         For an  additional  discussion  of  foreign  securities  and the  risks
involved  therein,  including  the  risks  of  currency  fluctuations,  see this
Prospectus  and the  Trust's SAI under  "Certain  Risk  Factors  and  Investment
Methods."

         Foreign  Currency  Transactions.  The  Portfolio may enter into forward
contracts  in order to protect  against  adverse  changes  in  foreign  currency
exchange  rates,  to  facilitate  transactions  in  foreign  securities  and  to
repatriate  dividend or interest  income  received  in foreign  currencies.  The
Portfolio  may enter into  contracts to purchase  foreign  currencies to protect
against an anticipated rise in the U.S. dollar price of securities it intends to
purchase. The Portfolio may also enter into contracts to sell foreign currencies
to  protect  against  a decline  in value of its  foreign  currency  denominated
portfolio securities due to a decline in the value of foreign currencies against
the U.S. dollar.

         If the  Portfolio  enters  into a  forward  contract  to  sell  foreign
currency, it may be required to place cash, fixed income or equity securities in
a segregated  account in an amount equal to the value of the  Portfolio's  total
assets  committed to the  consummation of the forward  contract.  Although these
contracts can protect the Portfolio from adverse  exchange  rates,  they involve
risk of  loss if the  Sub-advisor  fails  to  predict  foreign  currency  values
correctly.  For an additional  discussion of forward  contracts and their risks,
see this  Prospectus  and the  Trust's  SAI  under  "Certain  Risk  Factors  and
Investment Methods."

         Covered  Call  Options.  The  Portfolio  may try to reduce  the risk of
securities price changes (hedge) or generate income by writing (selling) covered
call options against  securities held in its portfolio having a market value not
exceeding 10% of its net assets and may purchase call options in related closing
transactions.  When the  Portfolio  writes  a  covered  call  option  against  a
security,  the  Portfolio is obligated to sell that security to the purchaser of
the  option  at a fixed  price at any  time  during a  specified  period  if the
purchaser  decides to  exercise  the option.  The  maximum  price the seller may
realize on the security during the option period is the fixed price.  The seller
continues to bear the risk of a decline in the security's  price,  although this
risk is  reduced,  at least in part,  by the  premium  received  for writing the
option.

         The writing of options is a highly specialized  activity which involves
investment  techniques and risks  different from those  associated with ordinary
portfolio  securities   transactions  including   transactional  expense,  price
volatility and a high degree of leverage. The writing of options could result in
significant  increases in the Portfolio's  turnover rate. The writing of options
also could  result in the  inability  of the  Portfolio  to  purchase  or sell a
security at a time that would  otherwise  be  favorable  for it to do so, or the
need for the Portfolio to sell a security at a disadvantageous  time, due to its
need to maintain  "cover" or to segregate  securities in connection with its use
of options. Options are considered derivatives.  For an additional discussion of
options and their risks,  see this Prospectus and the Trust's SAI under "Certain
Risk Factors and Investment Methods."

         When-Issued  Securities.  In a when-issued  transaction,  the Portfolio
commits to  purchase  securities  in order to secure an  advantageous  price and
yield at the time of the commitment  and pays for the  securities  when they are
delivered at a future date (generally within two months). If the seller fails to
complete the sale, the Portfolio may lose the  opportunity to obtain a favorable
price and yield.  When issued securities may decline or increase in value during
the period from the Portfolio's  investment  commitment to the settlement of the
purchase, which may magnify fluctuation in the Portfolio's net asset value.

         Repurchase  Agreements.  Subject to guidelines established by the Board
of Trustees of the Trust, the Portfolio may enter into repurchase agreements. In
a repurchase  agreement,  the Portfolio  buys a security from a Federal  Reserve
member bank, or a securities dealer and simultaneously agrees to sell it back at
a higher  price,  at a  specified  date,  usually  less than a week  later.  The
underlying  securities must fall within the Portfolio's  investment policies and
limitations. Under the repurchase agreement guidelines, the Sub-advisor monitors
the   creditworthiness  of  repurchase  agreement  sellers.  For  an  additional
discussion of repurchase agreements and certain risks involved therein, see this
Prospectus  under "Certain Risk Factors and Investment  Methods" and the Trust's
SAI under "Investment Objectives and Policies."

         Reverse Repurchase Agreements.  In a reverse repurchase agreement,  the
Portfolio sells securities to a bank or a securities dealer and at the same time
agrees to repurchase  the same  securities at a higher price on a specific date.
During the period  before the  repurchase,  the  Portfolio  continues to receive
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. Reverse  repurchase  agreements
may increase  fluctuations  in the Portfolio's net asset value and may be viewed
as a form of leverage.  The Sub-advisor monitors the creditworthiness of parties
to  reverse  repurchase  agreements.  For an  additional  discussion  of reverse
repurchase  agreements and certain risks involved  therein,  see this Prospectus
under  "Certain Risk Factors and  Investment  Methods" and the Trust's SAI under
"Investment Objectives and Policies."

         Short  Sales  Against-the-Box.  The  Portfolio  may  make  short  sales
against-the-box.  To effect a short sale,  the Portfolio  will borrow a security
from a brokerage  firm to make  delivery  to the buyer.  The  Portfolio  then is
obligated  to replace the  security  borrowed  at a later date.  A short sale is
"against-the-box"  when, at all times during which a short position is open, the
Portfolio owns an equal amount of such securities,  or owns securities giving it
the right,  without  payment  of  additional  consideration,  to obtain an equal
amount of securities sold short. Short sales against-the-box allow the Portfolio
to hedge against price fluctuations by locking in a sale price for securities it
does not wish to sell immediately.

CERTAIN RISK FACTORS AND INVESTMENT METHODS:

         Some of the risk factors related to certain securities, instruments and
techniques  that may be used by one or more of the  Portfolios  are described in
the "Investment  Objectives and Policies"  section of this Prospectus and in the
"Investment  Objectives  and Policies" and "Certain Risk Factors and  Investment
Methods"  sections of the Trust's SAI. The following is a description of certain
additional risk factors related to various of these securities,  instruments and
techniques.  The risks so  described  only apply to those  Portfolios  which may
invest in such securities and instruments or use such techniques.  Also included
is a general description of some of the investment  instruments,  techniques and
methods  which  may be  used  by one or  more  of the  Portfolios.  The  methods
described only apply to those Portfolios which may use such methods.

Derivative Instruments:

         To the extent permitted by the investment  objectives and policies of a
Portfolio,  a Portfolio may invest in securities and other  instruments that are
commonly  referred to as "derivatives."  For instance,  a Portfolio may purchase
and write call and put  options on  securities,  securities  indexes and foreign
currencies,  and  enter  into  futures  contracts  and use  options  on  futures
contracts,  and enter into swap agreements  with respect to foreign  currencies,
interest rates, and securities  indexes. A Portfolio may use these techniques to
hedge against  changes in interest  rates,  foreign  currency  exchange rates or
securities prices or as part of their overall investment strategies.

         In  general,  derivative  instruments  are  those  securities  or other
instruments  whose  value is derived  from or related to the value of some other
instrument or asset,  but not those securities whose payment of principal and/or
interest  depend  upon cash flows from  underlying  assets,  such as mortgage or
asset-backed  securities.  The value of some  derivative  instruments in which a
Portfolio  invests  may be  particularly  sensitive  to  changes  in  prevailing
interest rates, and, like the other  investments of a Portfolio,  the ability of
the Portfolio to successfully  utilize these instruments may depend in part upon
the ability of the  Sub-advisor  to forecast  interest  rates and other economic
factors correctly. If the Sub-advisor incorrectly forecasts such factors and has
taken positions in derivative  instruments contrary to prevailing market trends,
the Portfolio could be exposed to the risk of a loss.

         A Portfolio might not employ any of the derivative strategies described
below,  and no assurance can be given that any strategy used will succeed.  If a
Sub-advisor  incorrectly  forecasts  interest  rates,  market  values  or  other
economic  factors in  utilizing a  derivatives  strategy  for a  Portfolio,  the
Portfolio  might have been in a better  position if it had not entered  into the
transaction at all. The use of these strategies  involves certain special risks,
including a possible  imperfect  correlation,  or even no  correlation,  between
price  movements  of  derivative  instruments  and price  movements  of  related
investments. In addition, while some strategies involving derivative instruments
can reduce the risk of loss,  they can also reduce the  opportunity for gain, or
even  result in losses,  by  offsetting  favorable  price  movements  in related
investments.  Furthermore,  a  Portfolio  may be  unable to  purchase  or sell a
portfolio  security at a time that otherwise would be favorable for it to do so,
or need to sell a portfolio security at a disadvantageous  time, due to the need
to  maintain  asset  coverage  or  offsetting   positions  in  connection   with
transactions in derivative  instruments.  Finally,  a Portfolio may be unable to
close out or to liquidate its derivatives positions.

Options and Futures Contracts:

         Call  Options.  A call option on a security  gives the purchaser of the
option,  in return for a premium paid to the writer  (seller),  the right to buy
the  underlying  security  at the  exercise  price at any time during the option
period. Upon exercise by the purchaser, the writer (seller) of a call option has
the obligation to sell the  underlying  security at the exercise  price.  When a
Portfolio  purchases a call option,  it will pay a premium to the party  writing
the option and a commission to the broker  selling the option.  If the option is
exercised by such  Portfolio,  the amount of the premium and the commission paid
may be greater than the amount of the brokerage commission that would be charged
if the security  were to be  purchased  directly.  By writing a call  option,  a
Portfolio  assumes  the risk that it may be  required  to deliver  the  security
having a market  value  higher than its market  value at the time the option was
written.  The  Portfolio  will write call options in order to obtain a return on
its investments from the premiums  received and will retain the premiums whether
or not the options are  exercised.  Any decline in the market value of portfolio
securities  will be  offset  to the  extent  of the  premiums  received  (net of
transaction  costs).  If an option is  exercised,  the  premium  received on the
option will effectively increase the exercise price.

         If a Portfolio  writes a call option on a security it already  owns, it
gives up the  opportunity  for capital  appreciation  above the  exercise  price
should market price of the underlying security increase, but retains the risk of
loss should the price of the underlying security decline.

         A call option on a  securities  index is similar to a call option on an
individual security, except that the value of the option depends on the weighted
value of the group of securities  comprising the index,  and all settlements are
made in cash. A call option may be terminated by the writer (seller) by entering
into a closing purchase  transaction in which it purchases an option of the same
series as the option previously written.

         Put  Options.  A put option on a security  gives the  purchaser  of the
option, in return for premium paid to the writer (seller), the right to sell the
underlying  security at the exercise price at any time during the option period.
Upon exercise by the purchaser, the writer of a put option has the obligation to
purchase the underlying security at the exercise price. By writing a put option,
a Portfolio  assumes the risk that it may be required to purchase the underlying
security at a price in excess of its current market value.

         A put  option on a  securities  index is  similar to a put option on an
individual security, except that the value of the option depends on the weighted
value of the group of securities  comprising the index,  and all settlements are
made in cash.

         A  Portfolio  may  sell a call  option  or a put  option  which  it has
previously  purchased  prior to the purchase (in the case of a call) or the sale
(in the case of a put) of the underlying security. Any such sale would result in
a net gain or loss depending on whether the amount  received on the sale is more
or less than the  premium  and other  transaction  costs paid on the call or put
which is sold.

         Futures  Contracts and Related  Options.  A financial  futures contract
calls for  delivery of a particular  security at a specified  price at a certain
time in the future.  The seller of the contract  agrees to make  delivery of the
type of  security  called  for in the  contract  and the  buyer  agrees  to take
delivery at a specified future time. A Portfolio may also write call options and
purchase  put options on  financial  futures  contracts as a hedge to attempt to
protect the Portfolio's  securities  from a decrease in value.  When a Portfolio
writes a call option on a futures contract,  it is undertaking the obligation of
selling a  futures  contract  at a fixed  price at any time  during a  specified
period if the option is exercised.  Conversely, the purchaser of a put option on
a futures contract is entitled (but not obligated) to sell a futures contract at
a fixed price during the life of the option.

         Financial  futures contracts consist of interest rate futures contracts
and  securities  index  futures  contracts.  An interest  rate futures  contract
obligates  the seller of the  contract to  deliver,  and the  purchaser  to take
delivery of,  interest rate  securities  called for in a contract at a specified
future  time at a specified  price.  A stock index  assigns  relative  values to
common stocks included in the index and the index fluctuates with changes in the
market values of the common stocks included. A stock index futures contract is a
bilateral  contract pursuant to which two parties agree to take or make delivery
of an amount of cash equal to a specified  dollar  amount  times the  difference
between  the  stock  index  value at the  close of the last  trading  day of the
contract and the price at which the futures  contract is originally  struck.  An
option on a financial futures contract gives the purchaser the right 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 period of the option.

         Risks of Options and Futures  Contracts.  Futures contracts and options
can be highly  volatile and could result in  reduction  of a  Portfolio's  total
return,  and a Portfolio's  attempt to use such investments for hedging purposes
may not be  successful.  Successful  futures  strategies  require the ability to
predict future movements in securities prices, interest rates and other economic
factors.  A Portfolio's  potential losses from the use of futures extends beyond
its initial investment in such contracts.  Also, losses from options and futures
could be  significant  if a Portfolio is unable to close out its position due to
distortions in the market or lack of liquidity.

         The  use  of  futures  and  options   involves   investment  risks  and
transaction  costs to which a Portfolio  would not be subject  absent the use of
these  strategies.  If a  Sub-advisor  seeks  to  protect  a  Portfolio  against
potential adverse movements in the securities, foreign currency or interest rate
markets  using these  instruments,  and such  markets do not move in a direction
adverse  to the  Portfolio,  the  Portfolio  could  be left in a less  favorable
position than if such  strategies had not been used. The successful use of these
strategies  therefore may depend on the ability of the  Sub-advisor to correctly
forecast interest rate movements and general stock market price movements. Risks
inherent in the use of futures and options  include:  (a) the risk that interest
rates,  securities  prices and currency  markets will not move in the directions
anticipated;  (b) imperfect correlation between the price of futures and options
and movements in the prices of the  securities or currencies  being hedged;  (c)
the fact that skills needed to use these  strategies  are  different  from those
needed to select  portfolio  securities;  (d) the  possible  absence of a liquid
secondary market for any particular instrument at any time; and (e) the possible
need to  defer  closing  out  certain  hedged  positions  to avoid  adverse  tax
consequences. A Portfolio's ability to terminate option positions established in
the   over-the-counter   market  may  be  more  limited  than  in  the  case  of
exchange-traded  options and may also involve the risk that  securities  dealers
participating in such transactions  would fail to meet their obligations to such
Portfolio.

         The  use  of  options  and  futures  involves  the  risk  of  imperfect
correlation between movements in options and futures prices and movements in the
price of securities which are the subject of a hedge.  Particularly with respect
to options on stock  indices  and stock  index  futures,  the risk of  imperfect
correlation  increases as the  composition  of the  Portfolio  diverges from the
composition of the relevant index.

         Pursuant to regulations of the Commodity  Futures  Trading  Commission,
the Trust has represented that:

         (i) a Portfolio will not purchase or sell futures or options on futures
contracts  or  stock   indices  for  purposes   other  than  bona  fide  hedging
transactions  (as  defined  by the CFTC) if as a result  the sum of the  initial
margin  deposits  and  premiums  required  to  establish  positions  in  futures
contracts  and related  options that do not fall within the  definition  of bona
fide  hedging  transactions  would  exceed  5% of the fair  market  value of the
Portfolio's net assets; and

         (ii) a  Portfolio  will not enter  into any  futures  contracts  if the
aggregate  amount  of the  Portfolio's  commitments  under  outstanding  futures
contracts  positions  would  exceed the market  value of the  Portfolio's  total
assets.

Asset-Backed Securities:

         Asset-backed securities represent a participation in, or are secured by
and payable  from, a stream of payments  generated  by  particular  assets,  for
example,  credit card, automobile or trade receivables.  Asset-backed commercial
paper, one type of asset-backed security, is issued by a special purpose entity,
organized solely to issue the commercial paper and to purchase  interests in the
assets.  The  credit  quality of these  securities  depends  primarily  upon the
quality  of the  underlying  assets  and the  level  of  credit  support  and/or
enhancement provided.

         The underlying  assets (e.g.,  loans) are subject to prepayments  which
shorten the securities' weighted average life and may lower their return. If the
credit  support or  enhancement  is  exhausted,  losses or delays in payment may
result if the  required  payments of principal  and  interest are not made.  The
value of these  securities  also may change  because of changes in the  market's
perception  of the  creditworthiness  of the servicing  agent for the pool,  the
originator  of the pool,  or the  financial  institution  providing  the  credit
support or enhancement.

Mortgage-Backed Securities:

         Mortgage pass-through  securities are securities representing interests
in "pools" of mortgage loans secured by residential or commercial  real property
in which payments of both interest and principal on the securities are generally
made  monthly,  in  effect  "passing  through"  monthly  payments  made  by  the
individual borrowers on the mortgage loans which underlie the securities (net of
fees paid to the issuer or  guarantor  of the  securities).  Early  repayment of
principal on some  mortgage-related  securities  (arising  from  prepayments  of
principal due to sale of the underlying property,  refinancing,  or foreclosure,
net of fees and costs which may be incurred)  expose a Portfolio to a lower rate
of return  upon  reinvestment  of  principal.  Also,  if a  security  subject to
prepayment has been purchased at a premium, in the event of prepayment the value
of the premium would be lost. Like other fixed-income securities,  when interest
rates rise, the value of a  mortgage-related  security will  generally  decline;
however,  when  interest  rates are  declining,  the  value of  mortgage-related
securities  with  prepayment   features  may  not  increase  as  much  as  other
fixed-income  securities.  The value of these securities also may change because
of changes in the market's  perception  of the  creditworthiness  of the federal
agency or private  institution  that issued  them.  In  addition,  the  mortgage
securities   market  in  general  may  be  adversely   affected  by  changes  in
governmental regulation or tax policies.

         Collateralized Mortgage Obligations (CMOs):

         CMOs are obligations  fully  collateralized by a portfolio of mortgages
or  mortgage-related  securities.  Payments  of  principal  and  interest on the
mortgages are passed  through to the holders of the CMOs on the same schedule as
they are received,  although  certain  classes of CMOs have priority over others
with  respect  to  the  receipt  of  prepayments  on the  mortgages.  Therefore,
depending on the type of CMOs in which a Portfolio  invests,  the investment may
be  subject  to a greater  or lesser  risk of  prepayment  than  other  types of
mortgage-related  securities.  CMOs  may  also be  less  marketable  than  other
securities.

         Stripped Agency Mortgage-Backed Securities:

         Stripped Agency  Mortgage-Backed  securities  represent  interests in a
pool of mortgages,  the cash flow of which has been  separated into its interest
and principal components.  "IOs" (interest only securities) receive the interest
portion of the cash flow while "POs"  (principal  only  securities)  receive the
principal portion.  Stripped Agency Mortgage-Backed  Securities may be issued by
U.S.  Government  Agencies or by private issuers.  Unlike other debt instruments
and other mortgage-backed securities, the value of IOs tends to move in the same
direction as interest rates.

         The cash flows and yields on IO and PO classes are extremely  sensitive
to the  rate  of  principal  payments  (including  prepayments)  on the  related
underlying  mortgage  assets.  For  example,  a rapid or slow rate of  principal
payments  may  have a  material  adverse  effect  on the  prices  of IOs or POs,
respectively.   If  the  underlying  mortgage  assets  experience  greater  than
anticipated  prepayments of principal,  an investor may fail to recoup fully its
initial investment in an IO class of a stripped  mortgage-backed  security, even
if the IO class is rated AAA or Aaa or is  derived  from a full faith and credit
obligation. Conversely, if the underlying mortgage assets experience slower than
anticipated  prepayments of principal,  the price on a PO class will be affected
more  severely  than  would  be  the  case  with a  traditional  mortgage-backed
security.

Foreign Securities:

         Investments in securities of foreign issuers may involve risks that are
not present with domestic  investments.  While investments in foreign securities
are  intended  to  reduce  risk  by  providing  further  diversification,   such
investments  involve  sovereign  risk in  addition  to credit and market  risks.
Sovereign  risk includes  local  political or economic  developments,  potential
nationalization,  withholding  taxes  on  dividend  or  interest  payments,  and
currency  blockage  (which  would  prevent  cash from being  brought back to the
United  States).  Compared to United  States  issuers,  there is generally  less
publicly  available  information  about  foreign  issuers  and there may be less
governmental regulation and supervision of foreign stock exchanges,  brokers and
listed companies.  Brokerage commissions on foreign securities exchanges,  which
may be fixed,  are generally  higher than in the United States.  Foreign issuers
are not  generally  subject to uniform  accounting  and auditing  and  financial
reporting standards,  practices and requirements  comparable to those applicable
to domestic  issuers.  Securities  of some  foreign  issuers are less liquid and
their prices are more volatile than securities of comparable  domestic  issuers.
In some  countries,  there  may  also be the  possibility  of  expropriation  or
confiscatory  taxation,  limitations  on the  removal of funds or other  assets,
difficulty in enforcing  contractual and other obligations,  political or social
instability  or  revolution,  or  diplomatic  developments  which  could  affect
investments  in those  countries.  Settlement  of  transactions  in some foreign
markets may be delayed or less frequent than in the United  States,  which could
affect the liquidity of investments. For example, securities which are listed on
foreign  exchanges  or  traded in  foreign  markets  may trade on days  (such as
Saturday  or  Holidays)  when a  Portfolio  does not compute its price or accept
orders for the purchase,  redemption or exchange of its shares. As a result, the
net asset value of a Portfolio may be significantly  affected by trading on days
when shareholders  cannot make transactions.  Further,  it may be more difficult
for the Trust's agents to keep currently  informed about corporate actions which
may affect the price of portfolio  securities.  Communications  between the U.S.
and foreign countries may be less reliable than within the U.S.,  increasing the
risk of delayed settlements or loss of certificates for portfolio securities.

         Currency  Fluctuations.   Investments  in  foreign  securities  may  be
denominated  in  foreign   currencies.   The  value  of  Portfolio   investments
denominated in foreign currencies may be affected,  favorably or unfavorably, by
the relative  strength of the U.S. dollar,  changes in foreign currency and U.S.
dollar exchange rates and exchange control regulations.  A Portfolio's net asset
value per share may,  therefore,  be affected  by changes in  currency  exchange
rates.  Changes in foreign currency  exchange rates may also affect the value of
dividends  and  interest  earned,  gains  and  losses  realized  on the  sale of
securities  and net  investment  income and gains,  if any, to be distributed to
shareholders  by a Portfolio.  Foreign  currency  exchange  rates  generally are
determined  by the forces of supply and demand in foreign  exchange  markets and
the relative  merits of investment in different  countries,  actual or perceived
changes  in  interest  rates  or  other  complex   factors,   as  seen  from  an
international  perspective.   Currency  exchange  rates  also  can  be  affected
unpredictably by intervention by U.S. or foreign governments or central banks or
the failure to intervene,  or by currency controls or political  developments in
the U.S. or abroad. In addition,  a Portfolio may incur costs in connection with
conversions between various currencies. Investors should understand and consider
carefully the special risks involved in foreign investing.
These risks are often  heightened  for  investments  in  emerging or  developing
countries.

         The expected introduction of a single currency, the euro, on January 1,
1999 for  participating  nations in the European  Economic  and  Monetary  Union
presents  unique  uncertainties,  including  whether the payment and operational
systems of banks and other financial institutions will be ready by the scheduled
launch date; the legal treatment of certain outstanding financial contracts that
refer to existing currencies rather than the euro; the establishment of exchange
rates  for  existing  currencies  and the euro;  and the  creation  of  suitable
clearing and settlement payment systems for the new currency. Although the Trust
is taking steps intended to achieve  readiness for the planned  introduction  of
the euro, these or other external factors could cause market  disruptions before
or after the  introduction of the euro, and could adversely  affect the value of
securities held by the Portfolios.

         Developing  Countries.   Investing  in  developing  countries  involves
certain risks not typically  associated with investing in U.S.  securities,  and
imposes  risks  greater  than, or in addition to, risks of investing in foreign,
developed  countries.  These  risks  include:  the  risk of  nationalization  or
expropriation  of assets or confiscatory  taxation;  currency  devaluations  and
other  currency  exchange  rate  fluctuations;  social,  economic and  political
uncertainty  and  instability  (including  the  risk of war);  more  substantial
government  involvement  in  the  economy;  higher  rates  of  inflation;   less
government supervision and regulation of the securities markets and participants
in those markets; controls on foreign investment and limitations on repatriation
of invested  capital and on a Portfolio's  ability to exchange local  currencies
for U.S.  dollars;  unavailability  of currency  hedging  techniques  in certain
developing  countries;  the fact that  companies in developing  countries may be
smaller, less seasoned and newly organized companies; the difference in, or lack
of,   auditing  and  financial   reporting   standards,   which  may  result  in
unavailability of material  information  about issuers;  the risk that it may be
more difficult to obtain and/or enforce a judgment in a court outside the United
States;   and  greater  price  volatility,   substantially  less  liquidity  and
significantly smaller market capitalization of securities markets.

American Depositary Receipts ("ADRs"), European Depositary Receipts ("EDRs") and
Global Depositary Receipts ("GDRs"):

         ADRs are  dollar-denominated  receipts  generally  issued by a domestic
bank that represents the deposit of a security of a foreign issuer.  ADRs may be
publicly traded on exchanges or  over-the-counter in the United States. EDRs are
receipts  similar  to ADRs and are  issued  and  traded in  Europe.  GDRs may be
offered  privately  in the  United  States  and also  trade in public or private
markets in other  countries.  Depositary  Receipts may be issued as sponsored or
unsponsored  programs.  In sponsored programs,  the issuer makes arrangements to
have its securities traded in the form of a Depositary  Receipt.  In unsponsored
programs,  the  issuer  may not be  directly  involved  in the  creation  of the
program.   Although  regulatory  requirements  with  respect  to  sponsored  and
unsponsored   programs  are  generally  similar,   the  issuers  of  unsponsored
Depositary  Receipts are not obligated to disclose  material  information in the
United  States  and,  therefore,  the  import  of  such  information  may not be
reflected in the market value of such securities.

Forward Foreign Currency Exchange Contracts:

         A forward foreign currency  exchange contract involves an obligation to
purchase or sell a specified  currency at a future date,  which may be any fixed
number of days from the date the  contract is agreed upon by the  parties,  at a
price  set at the time of the  contract.  By  entering  into a  forward  foreign
currency contract, a Portfolio "locks in" the exchange rate between the currency
it will  deliver  and the  currency  it will  receive  for the  duration  of the
contract.  As a result, a Portfolio reduces its exposure to changes in the value
of the  currency it will  deliver and  increases  its exposure to changes in the
value of the currency into which it will exchange.  The effect on the value of a
Portfolio  is similar to selling  securities  denominated  in one  currency  and
purchasing  securities  denominated  in another.  The  Portfolios may enter into
these  contracts  for the  purposes of hedging  against  foreign  exchange  risk
arising from such Portfolio's investment or anticipated investment in securities
denominated  in or exposed to foreign  currencies.  Although a Sub-advisor  may,
from time to time,  seek to  protect a  Portfolio  by using  forward  contracts,
anticipated currency movements may not be accurately predicted and the Portfolio
may incur a gain or a loss on a forward contract.  A forward contract may reduce
a Portfolio's losses on securities  denominated in foreign currency,  but it may
also reduce the  potential  gain on the  securities  depending on changes in the
currency's value relative to the U.S. dollar or other currencies.

Lower-Rated High-Yield Bonds:

         Lower-rated  high-yield  bonds  (commonly  known as "junk  bonds")  are
generally  considered  to be high risk  investments,  as they are  subject  to a
higher risk of default than  higher-rated  bonds.  In  addition,  the market for
lower-rated  high-yield  bonds  generally  is more  limited  than the market for
higher-rated  bonds,  and because  their markets may be thinner and less active,
the market prices of  lower-rated  high-yield  bonds may fluctuate more than the
prices  of  higher-rated  bonds,  particularly  in times of  market  stress.  In
addition,  while the market for high-yield corporate debt securities has been in
existence for many years,  the market in recent years has experienced a dramatic
increase in the  large-scale  use of such  securities  to fund highly  leveraged
corporate acquisitions and restructurings.  Accordingly, past experience may not
provide an accurate  indication of future  performance  of the  high-yield  bond
market,  especially during periods of economic recession.  Other risks which may
be associated with  lower-rated  high-yield  bonds include:  the exercise of any
redemption  or call  provisions  in a  declining  market  may  result  in  their
replacement by lower yielding  bonds;  and  legislation,  from time to time, may
adversely  affect  their  market.  Since the risk of  default  is  higher  among
lower-rated  high-yield  bonds,  a  Sub-advisor's  research  and analysis are an
important  ingredient in the selection of lower-rated  high-yield bonds. Through
portfolio  diversification,  good  credit  analysis  and  attention  to  current
developments  and trends in interest rates and economic  conditions,  investment
risk may be reduced, although there is no assurance that losses will not occur.

Illiquid and Restricted Securities:

         The Board of  Trustees  of the Trust has  promulgated  guidelines  with
respect to illiquid  securities.  Illiquid securities are deemed as such because
they are subject to  restrictions on their resale  ("restricted  securities") or
because, based upon their nature or the market for such securities, they are not
readily marketable. Restricted securities are acquired through private placement
transactions,  directly from the issuer or from security  holders,  generally at
higher yields or on terms more favorable to investors than  comparable  publicly
traded securities. However, the restrictions on resale may make it difficult for
a  Portfolio  to  dispose  of  such  securities  at  the  time  considered  most
advantageous by its  Sub-advisor,  and/or may involve expenses that would not be
incurred in the sale of securities that were freely marketable. A Portfolio that
may  purchase  restricted  securities  may  qualify  for  and  trade  restricted
securities in the  "institutional  trading market"  pursuant to Rule 144A of the
Securities Act of 1933. Trading in the institutional trading market may enable a
Sub-advisor  to  dispose  of  restricted  securities  at a time the  Sub-advisor
considers  advantageous and/or at a more favorable price than would be available
if such securities were not traded in such market.  However,  the  institutional
trading market is relatively  new and liquidity of a Portfolio's  investments in
such market  could be impaired if trading  does not develop or  declines.  Risks
associated with restricted  securities  include the potential  obligation to pay
all or part of the  registration  expenses in order to sell  certain  restricted
securities.  A  considerable  period of time may elapse  between the time of the
decision to sell a security and the time a Portfolio may be permitted to sell it
under an effective  registration  statement.  If, during such a period,  adverse
conditions were to develop, a Portfolio might obtain a less favorable price than
prevailing when it decided to sell.

Repurchase Agreements:

         The Board of  Trustees  of the Trust has  promulgated  guidelines  with
respect to repurchase agreements.  Repurchase agreements are agreements by which
a Portfolio purchases a security and obtains a simultaneous  commitment from the
seller to repurchase  the security at an agreed upon price and date.  The resale
price is in excess of the purchase price and reflects an agreed upon market rate
unrelated to the coupon rate on the purchased security. A repurchase transaction
is usually  accomplished either by crediting the amount of securities  purchased
to the account of a Portfolio's  custodian maintained in a central depository or
book-entry  system or by physical  delivery of the  securities  to a Portfolio's
custodian in return for delivery of the purchase price to the seller. Repurchase
transactions  are  intended  to  be  short-term  transactions  with  the  seller
repurchasing the securities, usually within seven days.

         A Portfolio  which enters into a repurchase  agreement  bears a risk of
loss in the event  that the other  party to such an  agreement  defaults  on its
obligation and such Portfolio is delayed or prevented from exercising its rights
to  dispose  of the  collateral  securities,  including  the risk of a  possible
decline in value of the underlying  securities  during the period such Portfolio
seeks to assert  these  rights,  as well as the risk of  incurring  expenses  in
asserting  these  rights and the risk of losing  all or part of the income  from
such an agreement. If the seller institution defaults, a Portfolio might incur a
loss or delay in the  realization  of  proceeds  if the value of the  collateral
securing the repurchase  agreement declines and it might incur disposition costs
in liquidating the collateral.  In the event that such a defaulting seller filed
for  bankruptcy  or  became  insolvent,  disposition  of  such  securities  by a
Portfolio might be delayed pending court action.

Reverse Repurchase Agreements:

         In a reverse repurchase agreement,  a Portfolio transfers possession of
a portfolio  instrument to another person,  such as a broker-dealer or financial
institution in return for a percentage of the instrument's  market value in cash
and  agrees  that  on a  stipulated  date  in the  future  such  Portfolio  will
repurchase the portfolio instrument by remitting the original consideration plus
interest at an agreed upon rate. When effecting reverse  repurchase  agreements,
assets of a Portfolio,  in a dollar  amount  sufficient  to make payment for the
obligations to be repurchased, are segregated on such Portfolio's records at the
trade  date  and are  maintained  until  the  transaction  is  settled.  Reverse
repurchase  agreements  involve the risk that the market value of the securities
retained  by the  Portfolio  may  decline  below  the  repurchase  price  of the
securities which it is obligated to repurchase.

Borrowing:

         Each Portfolio's  borrowings are limited so that immediately after such
borrowing the value of the Portfolio's  assets  (including  borrowings) less its
liabilities (not including borrowings) is at least three times the amount of the
borrowings. Should a Portfolio, for any reason, have borrowings that do not meet
the above test then, within three business days, such Portfolio must reduce such
borrowings so as to meet the necessary  test.  Under such a  circumstance,  such
Portfolio may have to liquidate  securities at a time when it is disadvantageous
to do so. Gains made with additional funds borrowed will generally cause the net
asset  value of such  Portfolio's  shares to rise  faster than could be the case
without borrowings.  Conversely, if investment results fail to cover the cost of
borrowings,  the net asset value of such Portfolio could decrease faster than if
there had been no borrowings.

Convertible Securities and Warrants:

         Convertible  securities  generally  participate in the  appreciation or
depreciation of the underlying stock into which they are  convertible,  but to a
lesser  degree.  Warrants are options to buy a stated number of shares of common
stock at a specified  price any time during the life of the warrants.  The value
of warrants may fluctuate more than the value of the securities  underlying such
warrants.  The value of a warrant  detached  from its  underlying  security will
expire without value if the rights under such warrant are not exercised prior to
its expiration date.

Lending Portfolio Securities:

         Each Portfolio may lend securities with a value of up to 33 1/3% of its
total  assets to  broker-dealers,  institutional  investors,  or others  for the
purpose of  realizing  additional  income.  Voting  rights on loaned  securities
typically  pass to the  borrower,  although a Portfolio  is able to  terminate a
securities  loan,  usually  within  three  business  days,  in  order to vote on
significant  matters  or  for  other  reasons.  All  securities  loans  will  be
collateralized by cash or securities issued or guaranteed by the U.S. Government
or its  agencies  at least  equal in value  to the  market  value of the  loaned
securities.  Nonetheless,  lending securities involves certain risks,  including
the risk that the Portfolio  will be delayed or prevented  from  recovering  the
collateral if the borrower fails to return a loaned security.  For an additional
discussion  of  the  Portfolios'   limitations  on  lending,   see  "Fundamental
Investment Restrictions" in the Trust's SAI.

Other Investment Companies:

         The Trust has made  arrangements with certain money market mutual funds
so that the  Sub-advisors  for the various  Portfolios  can "sweep"  excess cash
balances of the Portfolios to those funds for temporary investment purposes.  In
addition,  certain  of the  Sub-advisors  may use money  market  funds that they
advise for temporary investment  purposes.  Mutual funds pay their own operating
expenses,  and the Portfolios,  as shareholders in the money market funds,  will
indirectly pay their proportionate share of such funds' expenses. Investments in
other  mutual  funds  and  investment  companies  will  be made  subject  to the
restrictions  of  the  Investment  Company  Act  of  1940,  which,  among  other
restrictions,  places certain  limits on the proportion of a Portfolio's  assets
that can be invested in other investment companies.

Year 2000 Risks:

         Many  services  provided  to  the  Trust  and  its  Portfolios  by  the
Investment  Manager,  the Sub-advisors,  and the Trust's other service providers
(collectively,  the  "Service  Providers")  rely  on the  functioning  of  their
respective  computer systems.  Many computer systems cannot distinguish the year
2000 from the year 1900,  with  resulting  potential  difficulty  in  performing
various  systems  functions  (the "Year 2000 Issue").  The Year 2000 Issue could
potentially  have an adverse  impact on the  handling  of security  trades,  the
payment of interest and  dividends,  pricing,  account  services and other Trust
operations.

         The Service  Providers  recognize the importance of the Year 2000 Issue
and have advised the Trust that they are taking  appropriate  steps necessary in
preparation  for the year 2000.  At this time,  there can be no  assurance  that
these steps will be  sufficient to avoid any adverse  impact on the  Portfolios,
nor can there be any assurance that the Year 2000 Issue will not have an adverse
effect  on  the  Portfolios'  investments  or on  global  markets  or  economies
generally. In addition, it has been reported that foreign institutions have made
less progress in addressing the Year 2000 Issue than major U.S. entities,  which
could adversely effect the Portfolio's foreign investments.

         The Investment Manager and the Trust have been informed that all of the
Service Providers  anticipate that their systems will be adapted in time for the
year 2000. The  Investment  Manager will continue to monitor the Year 2000 Issue
in an effort to confirm appropriate preparation by the Service Providers.

REGULATORY MATTERS:

         The Trust currently does not foresee any  disadvantages  to the holders
of variable annuity contracts and variable life insurance policies of affiliated
or unaffiliated Participating Insurance Companies or participants of the Skandia
Qualified Plan (see page 2 of this  Prospectus) or other plans  qualified  under
Section  401(a) of the Internal  Revenue Code of 1986, as amended,  arising from
the fact that the interests of the various holders of variable annuity contracts
and variable life insurance  policies and  participants  of qualified  plans may
differ due to  differences  of tax treatment or other  considerations  or due to
conflicts between the Participating  Insurance Companies and/or qualified plans.
Nevertheless,  the  Trustees  intend to monitor  events in order to identify any
material irreconcilable conflicts which may possibly arise and to determine what
action,  if any,  should be taken in response to such  conflicts.  The  variable
annuity  contracts  and variable  life  insurance  policies are described in the
separate prospectuses issued by the Participating Insurance Companies. The Trust
assumes no responsibility for such prospectuses.

PORTFOLIO TURNOVER:

         Each  Portfolio may  generally  change its  investments  at any time in
accordance with its Sub-advisor's  appraisal of factors affecting any particular
issuer or the market or economy in general.  The  frequency  of the  Portfolio's
transactions  -- the  Portfolio's  turnover  rate -- will vary from year to year
depending upon market  conditions.  High turnover  (generally in excess of 100%)
involves  correspondingly  greater  brokerage  commissions and other transaction
costs. Trading in fixed income securities does not generally involve the payment
of brokerage  commissions,  but does involve indirect  transaction costs. A 100%
portfolio  turnover  rate would occur if all the  securities  in a portfolio  of
investments were replaced during a given period.  The following  Portfolios have
anticipated annual rates of turnover exceeding 100%.

         AST JanCap  Growth  Portfolio  (not to exceed 200% under normal  market
conditions).

         AST Janus Small-Cap  Growth  Portfolio (not to exceed 200% under normal
market conditions).

         AST T. Rowe Price International Bond Portfolio (not to exceed 350%).

         AST Neuberger  Berman Mid-Cap Value Portfolio (not to exceed 150% under
normal market conditions).

         For  further  details  regarding  the  portfolio  turnover  rates,  see
"Portfolio Turnover" in the Trust's SAI.



<PAGE>


BROKERAGE ALLOCATION:

         Generally,  the primary  consideration in placing Portfolio  securities
transactions with broker-dealers is to obtain, and maintain the availability of,
execution  at the best net  price  available  and in the most  effective  manner
possible.  The Trust's brokerage allocation policy may permit a Portfolio to pay
a broker-dealer  which furnishes research services a higher commission than that
which might be charged by another  broker-dealer which does not furnish research
services,  provided that such commission is deemed reasonable in relation to the
value  of  the  services  provided  by  such  broker-dealer.   Each  Portfolio's
Sub-advisor may consider the use of broker-dealers  that are, or might be deemed
to be, their affiliates or affiliates of the Investment Manager. In addition,  a
Sub-advisor may consider sale of shares of the Portfolios or variable  insurance
products  that use the  Portfolios as  investment  vehicles,  or may consider or
follow  recommendations  of the  Investment  Manager  that take such  sales into
account,  as factors in  selection  of  broker-dealers  to effect  transactions,
subject  to the  requirements  of best net price  available  and most  favorable
execution.  In this regard,  the Investment  Manager has directed certain of the
Sub-advisors  to try to  effect  a  portion  of their  Portfolios'  transactions
through broker-dealers that give prominence to variable insurance products using
the Portfolios as investment  vehicles,  to the extent  consistent with best net
price  available  and most  favorable  execution.  For a complete  discussion of
portfolio  transactions and brokerage allocation,  see "Brokerage Allocation" in
the Statement of Additional Information.

INVESTMENT RESTRICTIONS:

         For each  Portfolio  the  Trust  has  adopted  a number  of  investment
restrictions  which are fundamental  policies and may not be changed without the
approval of the holders of a majority of the  affected  Portfolio's  outstanding
voting  securities as defined in the Investment  Company Act of 1940, as amended
(the "1940  Act").  The  Trust's  SAI  describes  all the  restrictions  on each
Portfolio's investment activities.

NET ASSET VALUES:

         The net asset  value  per  share of each  Portfolio  is  determined  by
dividing  the market  value of that  Portfolio's  securities  as of the close of
trading plus any cash or other assets (including dividends and accrued interest)
less all  liabilities  (including  accrued  expenses)  by the  number  of shares
outstanding in that Portfolio. Each Portfolio will determine the net asset value
of its shares as of 4:00 P.M. Eastern Time on each "business" day, which is each
day that the New York Stock  Exchange  (the  "NYSE") is open for  business.  The
Trust's Board of Trustees has established procedures for valuing the Portfolios'
securities.  In general, these valuations are based on market value. However, in
certain circumstances where market quotations are not readily available,  assets
are  valued  by  methods  specified  in the  procedures  that  are  believed  to
accurately  reflect the  assets'  fair value.  With  respect to all  Portfolios,
short-term  investments  that  will  mature  in 60 days or less  are  valued  at
amortized cost, which is intended to approximate  market value. See "Computation
of Net Asset Values" in the Trust's SAI.

PURCHASE AND REDEMPTION OF SHARES:

         Purchases  of shares  of the  Portfolios  may be made only by  separate
accounts  of  Participating  Insurance  Companies  for the  purpose  of  funding
variable annuity contracts and variable life insurance  policies or by Qualified
Plans.  The separate  accounts of the  Participating  Insurance  Companies place
orders to purchase and redeem  shares of the Trust based on, among other things,
the amount of premium  payments to be invested and the amount of  surrender  and
transfer requests (as defined in the prospectus  describing the variable annuity
contracts  and  variable  life  insurance  policies)  to be effected on that day
pursuant to variable  annuity  contracts and variable life  insurance  policies.
Orders received by the Trust or the Trust's  transfer agent are effected on days
on which the NYSE is open for  trading.  For orders  received  before  4:00 P.M.
Eastern time,  purchases and redemptions of the shares of the Trust are effected
at the net asset value per share determined as of 4:00 P.M. Eastern Time on that
same day. Orders received after 4:00 P.M.  Eastern Time are effected at the next
calculated net asset value.  Payment for redemptions will be made by the Trust's
transfer  agent on behalf of the Trust  within  seven days after the  request is
received.  The Trust does not assess any fees,  either  when it sells or when it
redeems its securities.  Surrender charges,  mortality and expense risk fees and
other charges may be assessed by  Participating  Insurance  Companies  under the
variable  annuity  contracts or variable  life  insurance  policies.  These fees
should be described in the Participating Insurance Companies' prospectuses.

         As of the date of this  Prospectus,  American  Skandia  Life  Assurance
Corporation  ("ASLAC") and Kemper Investors Life Insurance  Company are the only
Participating  Insurance  Companies.  In the future,  shares of the Trust may be
sold to and held by separate  accounts that fund  variable  annuity and variable
life  insurance   contracts   issued  by  other   affiliated  and   unaffiliated
Participating  Insurance  Companies and also  directly to the Skandia  Qualified
Plan and other qualified plans. While it is not anticipated, should any conflict
arise  between the holders of  variable  annuity  contracts  and  variable  life
insurance  policies of  Participating  Insurance  Companies and  participants in
qualified  plans which would require that a substantial  amount of net assets be
withdrawn from the Trust, orderly portfolio management could be disrupted to the
potential  detriment of such holders.  As of December 3, 1998,  more than 99% of
each Portfolio of the Trust was owned of record by ASLAC on behalf of the owners
of variable annuity contracts issued by ASLAC.

ORGANIZATION AND MANAGEMENT OF THE TRUST:

         The Trust is a managed,  open-end  investment  company  organized  as a
Massachusetts business trust, whose separate Portfolios are diversified,  unless
otherwise  indicated.  As  of  the  date  of  this  Prospectus,  the  Trust  has
twenty-nine Portfolios,  six of which are available through this Prospectus. The
Trust may offer additional Portfolios with a range of investment objectives that
Participating  Insurance  Companies may consider suitable for variable annuities
and variable  life  insurance  policies or that may be  considered  suitable for
Qualified  Plans. The Trust's current approach to achieving this goal is to seek
to have multiple  organizations  unaffiliated with each other be responsible for
conducting the investment  programs for the Portfolios.  Each such  organization
would  be   responsible   for  the   Portfolio  or   Portfolios  to  which  such
organization's expertise is best suited.

         Formerly,  the Trust was known as the  Henderson  International  Growth
Fund,  which  consisted  of only  one  Portfolio.  The  Investment  Manager  was
Henderson  International,  Inc.  Shareholders  of what  was,  at the  time,  the
Henderson  International Growth Fund, approved certain changes in a meeting held
April 17, 1992. These changes included  engagement of a new Investment  Manager,
engagement  of a Sub-advisor  and election of new  Trustees.  Subsequent to that
meeting,  the new Trustees adopted a number of resolutions,  including,  but not
limited to,  resolutions  renaming the Trust.  Since that time the Trustees have
adopted a number of  resolutions,  including,  but not  limited  to,  making new
Portfolios available and adopting forms of Investment  Management Agreements and
Sub-advisory  Agreements  between the  Investment  Manager and the Trust and the
Investment Manager and each Sub-advisor, respectively.

     The Trustees of the Trust have oversight  responsibility for the operations
of each Portfolio.  The Trustees are David E.A. Carson, Julian A. Lerner, Thomas
M. Mazzaferro,  Thomas M. O'Brien, F. Don Schwartz, Jan R. Carendi and Gordon C.
Boronow.  Additional  information  about the Trustees and the Trust's  executive
officers may be found in the Trust's SAI under the section "Management."

Company,  is also a  wholly-owned  subsidiary  of  American  Skandia  Investment
Holding Corporation. Certain officers of the Trust are officers and/or directors
of  one or  more  of the  following  companies:  ASISI,  American  Skandia  Life

Investment  Management  Agreements:   The  Trust  has  entered  into  Investment
Management Agreements with the Investment Manager (the "Management  Agreements")

with investment  advice and investment  management and  administrative  services
with respect to the applicable Portfolio subject to the supervision of the Board
of  Trustees  and in  conformity  with the  stated  policies  of the  applicable
Portfolio.  The Investment  Manager has engaged the Sub-advisors  noted above to
conduct the  investment  programs of each  Portfolio,  including  the  purchase,
retention and  disposition  of  securities.  Such  Sub-advisors  are required to
provide  research  and  statistical  analysis  and to keep books and  records of
securities  transactions.  The Investment  Manager is responsible for monitoring
the  activities  of the  Sub-advisors  and  reporting on the  activities  of the
Sub-advisors to the Trustees. The Investment Manager must also provide or obtain
for  the  Trust,  and  thereafter  supervise,  such  executive,  administrative,
accounting,  custody,  transfer agent and shareholder  servicing services as are
deemed advisable by the Trustees of the Trust.

         Under the terms of the Management  Agreements,  each Portfolio pays all
of its expenses, including, but not limited to, the costs incurred in connection
with the  maintenance of its  registration  under the Securities Act of 1933, as
amended,  and the 1940 Act, printing and mailing  prospectuses and statements of
additional information to shareholders,  certain office and financial accounting

expenses of trustee and shareholder meetings. Expenses incurred by the Trust not
directly  attributable to any specific  Portfolio or Portfolios are allocated on
the basis of the net assets of the respective Portfolios.

         The  Investment  Manager  receives a fee,  payable each month,  for the
performance  of its services.  The  Investment  Manager pays each  Sub-advisor a
portion  of such  fee for the  performance  of the  Sub-advisory  services.  The
Investment   Management  fee  payable   differs  from  Portfolio  to  Portfolio,
reflecting the objective,  policies and  restrictions  of each Portfolio and the
nature of each Investment Management Agreement and Sub-advisory Agreement.  Each
Portfolio's  fee is accrued daily for the purposes of  determining  the offering
and  redemption  price  of the  Portfolio's  shares.  The  fees  payable  to the
Investment Manager are as follows:

         AST JanCap  Growth  Portfolio:  An annual  rate of .90% of the  average
daily net assets of the Portfolio. The Investment Manager has voluntarily agreed

May 1, 1998, the Investment Manager had engaged Federated Investment  Counseling

Portfolio), for a total Investment Management fee equal to .75% of the first $50
million  of the  average  daily net  assets of the  Portfolio;  plus .60% of the
Portfolio's average daily net assets in excess of $50 million.

     The  Investment  Manager  has  agreed,  by  the  terms  of  the  Management
Agreements for certain  Portfolios of the Trust,  and  voluntarily for the other
Portfolios  of the Trust,  to  reimburse  the  Portfolio  for certain  operating
expenses  so that total  expenses  of the  Portfolio  do not exceed a  specified
percentage  of  the  Portfolio's   average  daily  net  assets.  Such  specified
percentage  differs between the Portfolios,  reflecting the objective,  policies
and  restrictions  of each Portfolio and the expenses  involved in conducting an
investment program for each Portfolio. For an additional discussion of Portfolio
expense limitations, see "Investment Advisory and Other Services" in the Trust's
SAI.

Sub-Advisory  Agreements:  The Investment  Manager pays each Sub-advisor for the
performance of sub-advisory  services.  The fee paid to the Sub-advisors differs
from   Portfolio  to  Portfolio,   reflecting  the   objectives,   policies  and
restrictions  of each Portfolio and the nature of each  Sub-advisory  Agreement.
Each  Sub-advisor's  fee is accrued daily for purposes of determining the amount
payable to the Sub-advisor.  The fees payable to the present Sub-advisors are as
follows:

Administrator:   PFPC  Inc.  (the   "Administrator"),   103  Bellevue   Parkway,
Wilmington,   Delaware  19809,  a  Delaware  corporation  that  is  an  indirect
wholly-owned  subsidiary of PNC Financial Corp., serves as the administrator for
the Trust pursuant to a Trust Accounting and  Administration  Agreement  between
the  Trust  and  the  Administrator,  dated  May 1,  1992  (the  "Administration
Agreement").   The   Administrator   provides   certain  fund   accounting   and
administrative  services  to  the  Trust,   including,   among  other  services,
accounting  relating to the Trust and investment  transactions of the Trust, and
computing  daily  net  asset  values.   The  Administrator  does  not  have  any
responsibility  or authority for the management of the assets of the Trust,  the
determination of its investment  policies,  or for any matter  pertaining to the
distribution of securities issued by the Trust.

         As  compensation  for  the  services  and  facilities  provided  by the
Administrator under the Administration Agreement, the Trust has agreed to pay to
the  Administrator  its  "out-of-pocket"  expenses  plus the  greater of certain
percentages  of the average  daily net assets of the Trust or certain  specified
minimum annual amounts  calculated for each  Portfolio.  The  percentages of the
average daily net assets are: (a) 0.10% of the first $200 million;  (b) 0.06% of
the next $200 million;  (c) 0.0375% of the next $200  million;  and (d) 0.03% of
average  daily net assets over $600 million.  The minimum  amount is $75,000 for
each  of the  AST  JanCap  Growth  Portfolio,  the  AST  INVESCO  Equity  Income
Portfolio,  and the AST Neuberger  Berman Mid-Cap Value  Portfolio.  The minimum
amount is $100,000 for the AST T. Rowe Price  International  Bond  Portfolio and
the  AST T.  Rowe  Price  International  Equity  Portfolio.  For  an  additional
discussion   of  the   services   provided  by  the   Administrator   under  the
Administration  Agreement,  and the "out-of-pocket" expenses the Trust is to pay
the  Administrator,  see the Trust's  SAI under  "Management  of the Trust:  The
Administrator and Transfer and Shareholder Servicing Agent."

Sale of Shares:  Shares are sold at net asset value to  Participating  Insurance
Companies and the Skandia  Qualified  Plan.  The Trust has entered into separate
agreements  for  the  sale  of  shares  with  American  Skandia  Life  Assurance
Corporation  ("ASLAC") and Kemper Investors Life Insurance  Company  ("Kemper"),
respectively.  Pursuant to these agreements, the Trust will pay ASLAC and Kemper
for printing and delivery of certain documents to the beneficial owners of Trust
shares who are holders of variable annuity and variable life insurance  policies
issued by ASLAC and Kemper. Such documents include prospectuses, semi-annual and
annual  reports and any proxy  materials.  The Trust will pay ASLAC 0.1%,  on an
annualized  basis,  of the net asset  value of the shares  legally  owned by any
separate account of ASLAC, and will pay Kemper 0.1%, on an annualized  basis, of
the net asset  value of the shares  legally  owned by the  separate  accounts of
Kemper named in the sales  agreement.  The Trust may enter into sales agreements
with other Participating  Insurance Companies in the future.  Owners of variable
annuity  contracts  and variable  insurance  policies  will  receive  annual and
semi-annual  reports  including the financial  statements of the Portfolios that
they have authorized for investment.

TAX MATTERS:

         This  discussion  of  federal  income tax  consequences  applies to the
Participating  Insurance  Companies  and  qualified  plans  since  the  separate
accounts of the Participating  Insurance  Companies and the qualified plans will
be the  shareholders  of the Trust.  Holders of variable  annuity  contracts  or
variable  life  insurance  policies  must  consult  the  prospectuses  of  their
respective  contracts  or policies  for  information  on the federal  income tax
consequences  to such  holders,  and plan  participants  must  consult  with any
applicable plan documents for information on the federal income tax consequences
to such holders.  The Trust intends to qualify as a regulated investment company
by satisfying the  requirements  under Subchapter M of the Internal Revenue Code
of 1986,  as  amended  (the  "Code"),  including  requirements  with  respect to
diversification  of assets,  distribution of income and sources of income. It is
the Trust's policy to distribute to  shareholders  all of its investment  income
(net of expenses)  and any capital  gains (net of capital  losses) in accordance
with the timing requirements  imposed by the Code so that the Trust will satisfy
the  distribution  requirement  of  Subchapter  M and not be  subject to federal
income taxes or the 4% excise tax.

         Distributions by the Trust of its net investment income and the excess,
if any, of its net short-term  capital gain over its net long-term  capital loss
are taxable to shareholders as ordinary income.  These distributions are treated
as  dividends  for federal  income tax  purposes,  but will  qualify for the 70%
dividends-received  deduction  for  corporate  shareholders  only to the  extent
designated as attributable  to dividends  received by the Trust in a notice from
the  Trust.  Distributions  by the  Trust  of the  excess,  if  any,  of its net
long-term  capital gain over its net  short-term  capital loss are designated as
capital gain  dividends  and are taxable to  shareholders  as long-term  capital
gains, regardless of the length of time the shareholder held his shares.

         Portions  of certain  Portfolio's  investment  income may be subject to
foreign income taxes withheld at source.  The Trust may elect to  "pass-through"
to the  shareholders of such Portfolios these foreign taxes, in which event each
shareholder  will be  required to include  his pro rata  portion  thereof in his
gross  income,  but will be able to deduct or (subject  to various  limitations)
claim a foreign tax credit for such amount.

         Distributions  to  shareholders  will be treated in the same manner for
federal income tax purposes whether received in cash or reinvested in additional
shares of the  Trust.  In  general,  distributions  by the Trust are taken  into
account by the shareholders in the year in which they are made. However, certain
distributions  made  during  January  will be treated as having been paid by the
Trust and received by the  shareholders  on December 31 of the preceding year. A
statement setting forth the federal income tax status of all distributions  made
or deemed made during the year,  including  any amount of foreign  taxes "passed
through,"  will be sent to  shareholders  promptly  after the end of each  year.
Notwithstanding  the foregoing,  distributions by the Trust to certain Qualified
Plans may be exempt from federal income tax.

         Under Code  Section  817(h),  a segregated  asset  account upon which a
variable  annuity  contract or variable life  insurance  policy is based must be
"adequately   diversified."  A  segregated  asset  account  will  be  adequately
diversified if it satisfies one of two  alternative  tests set forth in Treasury
regulations.   For  purposes  of  these  alternative  diversification  tests,  a
segregated asset account investing in shares of a regulated  investment  company
will be entitled to "look-through"  the regulated  investment company to its pro
rata  portion  of  the  regulated  investment  company's  assets,  provided  the
regulated  investment  company  satisfies  certain  conditions  relating  to the
ownership  of  its  shares.   The  Trust  intends  to  satisfy  these  ownership
conditions.  Further,  the Trust intends that each Portfolio  separately will be
adequately diversified. Accordingly, a segregated asset account investing solely
in shares of a Portfolio will be adequately diversified,  and a segregated asset
account  investing in shares of one or more Trust Portfolios and shares of other
adequately diversified funds generally will be adequately diversified.

         The foregoing discussion of federal income tax consequences is based on
tax laws and  regulations  in  effect  on the  date of this  Prospectus,  and is
subject to change by  legislative  or  administrative  action.  As the foregoing
discussion is for general information only, each prospective  shareholder should
consult with his own tax advisor as to the tax  consequences  of  investments in
the Trust,  including the  application of state and local taxes which may differ
from the federal income tax consequences described above.

DESCRIPTION OF SHARES OF THE TRUST:

         The Trust's  Declaration of Trust dated October 31, 1988, which governs
certain Trust  matters,  permits the Trust's Board of Trustees to issue multiple
classes of shares,  and within  each  class,  an  unlimited  number of shares of
beneficial interest with a par value of $.001 per share. Each share entitles the
holder to one vote for the  election of Trustees  and on all other  matters that
are  not  specific  to one  class  of  shares,  and to  participate  equally  in
dividends,  distributions  of capital  gains and net  assets of each  applicable
Portfolio.  Only  shareholders  of shares of a  specific  Portfolio  may vote on
matters  specific to that  Portfolio.  Shares of one class may not bear the same
economic  relationship  to the Trust as shares of another class. In the event of
dissolution  or  liquidation,  holders of shares of a Portfolio will receive pro
rata, subject to the rights of creditors, the proceeds of the sale of the assets
held in such  Portfolio less the  liabilities  attributable  to such  Portfolio.
Shareholders of a Portfolio will not be liable for the expenses,  obligations or
debts of another Portfolio.

         There are no preemptive or conversion  rights  applicable to any of the
Trust's  shares.  The  Trust's  shares,   when  issued,   will  be  fully  paid,
non-assessable and transferable.  The Trustees may at any time create additional
series of shares without shareholder approval.

         Generally, there will not be annual meetings of shareholders. A Trustee
may, in accordance with certain rules of the Securities and Exchange Commission,
be removed from office when the holders of record of not less than two-thirds of
the  outstanding  shares  either  present a written  declaration  to the Trust's
custodian or vote in person or by proxy at a meeting called for this purpose. In
addition,  the Trustees will promptly call a meeting of shareholders to remove a
Trustee(s) when requested to do so in writing by record holders of not less than
10%  of  the  outstanding  shares.  Finally,  the  Trustees  shall,  in  certain
circumstances,  give  such  shareholders  access  to a  list  of the  names  and
addresses of all other shareholders or inform them of the number of shareholders
and the cost of mailing their request.

         Under   Massachusetts   law,    shareholders   could,   under   certain
circumstances,  be held liable for the  obligations of the Trust.  However,  the
Declaration of Trust disclaims  shareholder liability for acts or obligations of
the  Trust  and  requires  that  notice  of such  disclaimer  be  given  in each
agreement, obligation or instrument entered into or executed by the Trust or the
Trustees to all parties,  and each party thereto must expressly waive all rights
of action directly against  shareholders.  The Declaration of Trust provides for
indemnification  out of the  Trust's  property  for all loss and  expense of any
shareholder  of the Trust  held  liable  on  account  of being or having  been a
shareholder. Thus, the risk of a shareholder incurring financial loss on account
of shareholder liability is limited to circumstances in which the Trust would be
unable to meet its obligations  wherein the complaining party was held not to be
bound by the disclaimer.

         The Declaration of Trust further provides that the Trustees will not be
liable for errors of judgment or  mistakes of fact or law.  However,  nothing in
the  Declaration of Trust protects a Trustee  against any liability to which the
Trustee would otherwise be subject by reason of willful misfeasance,  bad faith,
gross negligence,  or reckless  disregard of the duties involving the conduct of
his office.  The Declaration of Trust provides for  indemnification by the Trust
of the  Trustees  and officers of the Trust except with respect to any matter as
to which any such person did not act in good faith in the reasonable belief that
his action was in or not opposed to the best interests of the Trust. Such person
may not be  indemnified  against  any  liability  to the  Trust  or the  Trust's
shareholders  to which he would  otherwise  be  subject  by  reason  of  willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of his office.  The Declaration of Trust also authorizes
the purchase of liability insurance on behalf of Trustees and officers.

PERFORMANCE:

         The Portfolios may measure performance in terms of total return,  which
is  calculated  for any  specified  period of time by assuming  the  purchase of
shares of the  Portfolio at the net asset value at the  beginning of the period.
Each dividend or other distribution paid by each Portfolio during such period is
assumed to have been reinvested at the net asset value on the reinvestment date.
The shares  then owned as a result of this  process  are valued at the net asset
value  at the end of the  period.  The  percentage  increase  is  determined  by
subtracting  the  initial  value of the  investment  from the  ending  value and
dividing the remainder by the initial value. Each Portfolio's total return shows
a Portfolio's overall dollar or percentage change in value, including changes in
share  price  and  assuming  each   Portfolio's   dividends  and  capital  gains
distributions  are  reinvested.  An average  annual  total  return  reflects the
hypothetical  annually  compounded  return  that  would have  produced  the same
cumulative return if a Portfolio's performance had been constant over the entire
period.  Total  return  figures  are based on the  overall  change in value of a
hypothetical  investment in each  Portfolio.  Because average annual returns for
more than one year tend to smooth out  variations  in each  Portfolio's  return,
investors  should  recognize  that  such  figures  are  not the  same as  actual
year-by-year  results.  To illustrate the components of overall  performance,  a
Portfolio may separate its  cumulative  and average  annual  returns into income
results and capital gains or losses.

         The  Portfolios may also measure  performance  in terms of yield.  Each
Portfolio's  yield  shows  the  rate  of  income  the  Portfolio  earns  on  its
investments as a percentage of the Portfolio's  share price. To calculate yield,
the  Portfolio  takes the  interest  and  dividend  income  it  earned  from its
investments  for a 30-day  period (net of  expenses),  divides it by the average
number of Portfolio  shares  entitled to receive  dividends,  and  expresses the
result as an annualized percentage rate based on the Portfolio's net asset value
at the end of the 30-day period. For the Portfolio's  investments denominated in
foreign  currencies,  income and expenses  are  calculated  in their  respective
currencies and then converted to U.S. dollars.  Yields are calculated  according
to methods that are  standardized  for all stock and bond funds.  Because  yield
calculation  methods differ from the method used for other  accounting  purposes
(for  instance,  currency  gains  and  losses  are not  reflected  in the  yield
calculation), a Portfolio's yield may not equal the income paid to shareholders'
accounts or the income reported in the Portfolio's financial statements.

         The  Portfolios  impose no sales or other charges that would impact the
total return or yield computations. Portfolio performance figures are based upon
historical  results and are not  intended to indicate  future  performance.  The
investment  return and principal value of an investment in any of the Portfolios
will fluctuate so that an investor's shares, when redeemed, may be worth more or
less than their original cost.

         Yield and total returns quoted from the  Portfolios  include the effect
of deducting each Portfolio's expenses, but may not include charges and expenses
attributable  to  any  particular  insurance  product.  Because  shares  of  the
Portfolios may be purchased through variable insurance contracts, the prospectus
of the  Participating  Insurance  Company  sponsoring  such  contract  should be
carefully  reviewed for information on relevant charges and expenses.  Excluding
these charges from quotations of each Portfolio's  performance has the effect of
increasing  the  performance  quoted.  The  effect  of these  charges  should be
considered  when  comparing a  Portfolio's  performance  to that of other mutual
funds. In advertising and sales literature, these figures will be accompanied by
figures that reflect the applicable contract charges.

         From time to time in advertisements  or sales material,  the Portfolios
(or Participating  Insurance Companies) may discuss their performance ratings or
other  information as published by recognized  mutual fund statistical or rating
services,   such  as  Lipper  Analytical  Services,   Inc.,  Morningstar  or  by
publications of general  interest,  such as Forbes or Money.  The Portfolios may
also compare their  performance to that of other selected  mutual funds,  mutual
fund averages or recognized  stock market  indicators,  including the Standard &
Poor's  500  Stock  Index,  the  Standard  & Poor  Midcap  Index,  the Dow Jones
Industrial Average, the Russell 2000 and the NASDAQ composite.  In addition, the
Portfolios may compare their total return or yield to the yield on U.S. Treasury
obligations  and to the percentage  change in the Consumer Price Index.  Each of
the  AST T.  Rowe  Price  International  Equity  Portfolio,  AST T.  Rowe  Price
International  Bond  Portfolio,  may  compare its  performance  to the record of
global market  indicators such as Morgan Stanley Capital  International  Europe,
Australia,  Far East Index (EAFE Index),  an unmanaged  index of foreign  common
stock  prices  translated  into  U.S.  dollars.   Such  performance  ratings  or
comparisons  may  be  made  with  funds  that  may  have  different   investment
restrictions,  objectives,  policies or techniques  than the Portfolios and such
other funds or market  indicators  may be  comprised of  securities  that differ
significantly from the Portfolios' investments.
