RISK/RETURN SUMMARY

American Skandia Trust (the "Trust") is comprised of thirty-three
investment portfolios, eight of which are offered through this Prospectus (the
"Portfolios"). The Portfolios are designed to provide a wide range of investment
options. Each Portfolio has its own investment goal and style (and, as a result,
its own level of risk). Some of the Portfolios offer potential for high returns
with correspondingly higher risk, while others offer stable returns with
relatively less risk. It is possible to lose money when investing even in the
most conservative of the Portfolios. Investments in the Portfolios are not bank
deposits and are not insured or guaranteed by the Federal Deposit Insurance
Corporation or any other government agency.

It is not possible to provide an exact measure of the risk to which a
Portfolio is subject, and a Portfolio's risk will vary based on the securities
that it holds at a given time. Nonetheless, based on each Portfolio's investment
style and the risks typically associated with that style, it is possible to
assess in a general manner the risks to which a Portfolio will be subject. The
following discussion highlights the investment strategies and risks of each
Portfolio. Additional information about each Portfolio's potential investments
and its risks is included in this Prospectus under "Investment Objectives and
Policies."

</TABLE>

Principal Investment Strategies:

The AST American Century International Growth Portfolio will seek to achieve its
investment objective by investing primarily in equity securities of
international companies that the Sub-advisor believes will increase in value
over time. The Sub-advisor uses a growth investment strategy it developed that
looks for companies with earnings and revenue growth. Ideally, the Sub-advisor
looks for companies whose earnings and revenues are not only growing, but are
growing at an accelerating pace. For purposes of the Portfolio, equity
securities include common stocks, preferred stocks and convertible securities.

The Sub-advisor tracks financial information for thousands of companies to
research and select the stocks it believes will be able to sustain accelerating
growth. This strategy is based on the premise that, over the long term, the
stocks of companies with accelerating earnings and revenues have a
greater-than-average chance to increase in value.

The Sub-advisor recognizes that, in addition to locating strong companies with
accelerating earnings, the allocation of assets among different countries and
regions also is an important factor in managing an international portfolio. For
this reason, the Sub-advisor will consider a number of other factors in making
investment selections, including the prospects for relative economic growth
among countries or regions, economic and political conditions, expected
inflation rates, currency exchange fluctuations and tax considerations. Under
normal conditions, the Portfolio will invest at least 65% of its assets in
equity securities of issuers from at least three countries outside of the United
States. While the Portfolio's focus will be on issuers in developed markets, the
Sub-advisor expects to invest to some degree in issuers in developing countries.

The AST American Century International Growth Portfolio II (formerly, the AST T.
Rowe Price International Equity Portfolio) will seek to achieve its investment
objective in the same manner as the AST American Century International Growth
Portfolio as described above.

<PAGE>

Principal Risks:

o The international portfolios are equity funds, and the primary risk of each
is that the value of the stocks they hold will decline. Stocks can decline
for many reasons, including reasons related to the particular company, the
industry of which it is a part, or the securities markets generally.

o The level of risk of the international portfolios will generally be higher
than the level of risk associated with domestic equity funds. Foreign
investments involve risks such as fluctuations in currency exchange rates,
less liquid and more volatile securities markets, unstable political and
economic structures, reduced availability of information, and lack of
uniform financial reporting and regulatory practices such as those that
apply to U.S. issuers. While none of the international portfolios invest
primarily in companies located in developing countries, each may invest in
those companies to some degree, and the risks of foreign investment may be
accentuated by investment in developing countries.

Capital Growth Portfolios:

Portfolio: Investment Goal: Primary Investments:
- --------- --------------- -------------------

<S> <C> <C>
Janus Small-Cap Growth Capital growth The Portfolio invests primarily in common stocks of small
capitalization companies.

Neuberger Berman Mid-Cap Capital growth The Portfolio invests primarily in common stocks of medium
Value capitalization companies, using a value-oriented investment
approach.

Alger All-Cap Growth Long-term capital growth The Portfolio invests primarily in common and preferred
stocks.

JanCap Growth Capital growth The Portfolio invests primarily in common stocks.
</TABLE>

Principal Investment Strategies:

The AST Janus Small-Cap Growth Portfolio pursues its objective by normally
investing at least 65% of its total assets in the common stocks of small-sized
companies. For purposes of the Portfolio, small-sized companies are those that
have market capitalizations of less than $1.5 billion or annual gross revenues
of less than $500 million. To a lesser extent, the Portfolio may also invest in
stocks of larger companies with potential for capital appreciation.

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 similar selection
procedure.

To pursue its objective, the AST Neuberger Berman Mid-Cap Value Portfolio
primarily invests in the common stocks of mid-cap companies. Some of the
Portfolio's assets may be invested in the securities of large-cap companies as
well as in small-cap companies. The Portfolio seeks to reduce risk by
diversifying among many companies and industries.

Under the Portfolio's value-oriented investment approach, the Sub-advisor looks
for well-managed companies whose stock prices are undervalued and that may rise
in price when other investors realize their worth. Factors that the Sub-advisor
may use to identify these companies include strong fundamentals, such as a low
price-to-earnings ratio, consistent cash flow, and a sound track record through
all phases of the market cycle. The Sub-advisor may also look for other
characteristics in a company, such as a strong position relative to competitors,
a high level of stock ownership among management, or a recent sharp decline in
stock price that appears to be the result of a short-term market overreaction to
negative news.

The Sub-advisor generally considers selling a stock when it reaches a target
price, when it fails to perform as expected, or when other opportunities appear
more attractive.

The AST Alger All-Cap Growth Portfolio invests primarily in equity securities,
such as common or preferred stocks, that are listed on U.S. exchanges or in the
over-the-counter market. The Portfolio may invest in the equity securities of
companies of all sizes, and may emphasize either larger or smaller companies at
a given time based on the Sub-advisor's assessment of particular companies and
market conditions.

The Portfolio invests primarily in growth stocks. The Sub-advisor believes that
these stocks are those of two types of companies:

o High Unit Volume Growth Companies. Vital creative companies that offer
goods or services to a rapidly expanding marketplace. They include both
established and emerging firms, offering new or improved products, or firms
simply fulfilling an increased demand for an existing product line.

o Positive Life Cycle Change Companies. Companies experiencing a major change
that is expected to produce advantageous results. These changes may be as
varied as new management, products or technologies, restructurings or
reorganizations, or mergers and acquisitions.

The AST JanCap Growth Portfolio will pursue its objective by investing primarily
in common stocks. Common stock investments will be in 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. The Sub-advisor generally takes a "bottom up" approach to choosing
investments for the Portfolio. In other words, the Sub-advisor seeks to identify
individual companies with earnings growth potential that may not be recognized
by the market at large.

Principal Risks:

o All of the capital growth portfolios are equity funds, and the primary risk
of each is that the value of the stocks they hold will decline. Stocks can
decline for many reasons, including reasons related to the particular
company, the industry of which it is a part, or the securities markets
generally. These declines can be substantial.

o The risk to which the capital growth portfolios are subject depends in part
on the size of the companies in which the particular portfolio invests.
Securities of smaller companies tend to be subject to more abrupt and
erratic price movements than securities of larger companies, in part
because they may have limited product lines, markets, or financial
resources. Market capitalization, which is the total market value of a
company's outstanding stock, is often used to classify companies based on
size. Therefore, the AST Janus Small-Cap Growth Portfolio can be expected
to be subject to the highest degree of risk relative to the other capital
growth funds. The AST Neuberger Berman Mid-Cap Value Portfolio can be
expected to be subject to somewhat less risk, and the AST JanCap Growth
Portfolio to somewhat less risk than the mid-cap fund. The AST Alger
All-Cap Growth Portfolio may invest in equity securities of companies
without regard to capitalization, and may include large and small companies
at the same time.

o The AST Janus Small-Cap Growth Portfolio, the AST Alger All-Cap Growth
Portfolio, and the JanCap Growth Portfolio generally take a growth approach
to investing, while the AST Neuberger Berman Mid-Cap Value Portfolio
generally takes a value approach. Value stocks are believed to be selling
at prices lower than what they are actually worth, while growth stocks are
those of companies that are expected to grow at above-average rates. A
portfolio investing primarily in growth stocks will tend to be subject to
more risk than a value fund, although this will not always be the case.

<TABLE>
<CAPTION>
Growth and Income Portfolios:

Portfolio: Investment Goal: Primary Investments:
- --------- --------------- -------------------

<S> <C> <C>
INVESCO Equity Income Capital growth and current The Portfolio invests primarily in dividend-paying common and
income preferred stocks, and to a lesser extent in fixed income
securities.
</TABLE>

Principal Investment Strategies:

The AST INVESCO Equity Income Portfolio seeks to achieve its objective by
investing in securities that are expected to produce relatively high levels of
income and consistent, stable returns. The Portfolio normally will invest at
least 65% of its assets in dividend-paying common and preferred stocks of
domestic and foreign issuers. Up to 30% of the Portfolio's assets may be
invested in equity securities that do not pay regular dividends. In addition,
the Portfolio normally will have some portion of its assets invested in debt
securities or convertible bonds.

Principal Risks:

o Both equity securities (e.g., stocks) and fixed income securities (e.g.,
bonds) can decline in value, and the primary risk of each of the growth and
income portfolios is that the value of the securities they hold will
decline. The degree of risk to which the growth and income portfolios are
subject is likely to be somewhat less than a portfolio investing
exclusively for capital growth. Nonetheless, the share prices of the growth
and income portfolios can decline substantially.

o The AST INVESCO Equity Income Portfolio invests primarily in equity
securities, but will normally invest some of its assets in fixed income
securities. The values of equity securities tend to fluctuate more widely
than the values of fixed income securities. Therefore, the Portfolio will
likely be subject to somewhat higher risk than a portfolio that invests
more heavily in fixed income securities.

o The AST INVESCO Equity Income Portfolio may invest to some degree in
lower-quality fixed income securities, which are subject to greater risk
that the issuer may fail to make interest and principal payments on the
securities when due. The Portfolio generally invests in intermediate- to
long-term fixed income securities. Fixed income securities with longer
maturities are generally subject to greater risk than fixed income
securities with shorter maturities, in that their values will fluctuate
more in response to changes in market interest rates.

<TABLE>
<CAPTION>
Fixed Income Portfolios:

Portfolio: Investment Goal: Primary Investments:
- --------- --------------- -------------------

<S> <C> <C>
T. Rowe Price Global Bond High current income and The Portfolio invests primarily in high-quality foreign and
capital growth U.S. government bonds.
</TABLE>

Principal Investment Strategies:

To achieve its objectives, the AST T. Rowe Price Global Bond Portfolio
(formerly, the AST T. Rowe Price International Bond Portfolio) will invest at
least 65% of its total assets in bonds issued or guaranteed by the U.S. or
foreign governments or their agencies and by foreign authorities, provinces and
municipalities. Corporate bonds may also be purchased. The Portfolio 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 Sub-advisor believes that the currency risk can be minimized through
hedging.

Although the Portfolio expects to maintain an intermediate-to-long weighted
average maturity, there are no maturity restrictions on the overall portfolio or
on individual securities. The Portfolio may and frequently does engage in
foreign currency transactions such as forward foreign currency exchange
contracts, hedging its foreign currency exposure back to the dollar or against
other foreign currencies ("cross-hedging"). The Sub-advisor also attempts to
reduce currency 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 the aggregate in below
investment-grade, high-risk bonds ("junk bonds") and emerging market bonds. Some
emerging market bonds, such as Brady Bonds, may be denominated in U.S. dollars.

Principal Risks:

o The risk of a fund or portfolio investing primarily in fixed income
securities is determined largely by the quality and maturity
characteristics of its portfolio securities. Lower-quality fixed income
securities are subject to greater risk that the company may fail to make
interest and principal payments on the securities when due. Fixed income
securities with longer maturities (or durations) are generally subject to
greater risk than securities with shorter maturities, in that their values
will fluctuate more in response to changes in market interest rates.

<PAGE>

Whilethe AST T. Rowe Price Global Bond Portfolio invests primarily in
high-quality fixed income securities, its substantial investments in foreign
fixed income securities and relatively long average maturity will tend to
increase its level of risk. Like foreign equity investments, foreign fixed
income investments involve risks such as fluctuations in currency exchange
rates, unstable political and economic structures, reduced availability of
information, and lack of uniform financial reporting and regulatory practices
such as those that apply to U.S. issuers. The AST T. Rowe Price Global Bond
Portfolio can invest to some degree in securities of issuers in developing
countries and in lower-quality fixed income securities, and the risks of the
Portfolio may be accentuated by these holdings.

Past Performance

The bar charts show the performance of each Portfolio for each full
calendar year the Portfolio has been in operation. The tables below each bar
chart show each such Portfolio's best and worst quarters during the periods
included in the bar chart, as well as average annual total returns for each
Portfolio since inception. This information may help provide an indication of
each Portfolio's risks by showing changes in performance from year to year and
by comparing the Portfolio's performance with that of a broad-based securities
index. The performance figures do not reflect any charges associated with the
variable insurance contracts through which Portfolio shares are purchased; and
would be lower if they did. All figures assume reinvestment of dividends. Past
performance does not necessarily indicate how a Portfolio will perform in the
future.

(1) This Portfolio commenced operations in January 2000. "Other expenses" shown
are based on estimated amounts for the fiscal year ending December 31, 2000.

(2) As discussed below under "Management of the Trust - Fees and Expenses, the
Trustees adopted a Distribution Plan (the "Distribution Plan") under Rule 12b-1
to permit an affiliate of the Trust's Investment Manager to receive brokerage
commissions in connection with purchases and sales of securities held by the
Portfolios, and to use these commissions to promote the sale of shares of the
Portfolio. While the brokerage commission rates and amounts paid by the various
Portfolios are not expected to increase as a result of the Distribution Plan,
the staff of the Securities and Exchange Commission recently takes the position
that commission amounts received under the Distribution Plan should be reflected
as distribution expenses of the Funds. The Distribution Fee estimates are
derived and annualized from data regarding commission amounts directed to the
affiliate under the Distribution Plan from such Plan's commencement of
operations for each Portfolio (in late July through early August 1999) until
December 31, 1999. Actual commission amounts directed under the Distribution
Plan will vary and the amounts directed during the first full fiscal year of the
Plan's operations may differ substantially from the annualized amounts listed in
the above chart.

(3) The Investment Manager has agreed to reimburse and/or waive fees for certain
Portfolios until at least April 30, 2001. The caption "Total Annual Fund
Operating Expenses" reflects the Portfolios' fees and expenses before such
waivers and reimbursements, while the caption "Net Annual Fund Operating
Expenses" reflects the effect of such waivers and reimbursements.

EXPENSE EXAMPLES:

This example is intended to help you compare the cost of investing in
the Portfolios with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in a Portfolio for the time
periods indicated. The Example also assumes that your investment has a 5% return
each year, that the Portfolios' total operating expenses remain the same, and
that any expense waivers and reimbursements remain in effect only for the
periods during which they are binding. Although your actual costs may be higher
or lower, based on these assumptions your costs would be:

INVESTMENT OBJECTIVES AND POLICIES:

The investment objective, policies and limitations for each of the
Portfolios are described below. While certain policies apply to all Portfolios,
generally each Portfolio has a different investment objective and investment
focus. As a result, the risks, opportunities and returns of investing in each
Portfolio will differ. The investment objectives and policies of the Portfolios
generally are not fundamental policies and may be changed by the Trustees
without shareholder approval.

There can be no assurance that the investment objective of any
Portfolio will be achieved. Risks relating to certain types of securities and
instruments in which the Portfolios may invest are described in this Prospectus
under "Certain Risk Factors and Investment Methods."

If approved by the Trustees, the Trust may add more Portfolios and may
cease to offer any existing Portfolios in the future.

AST AMERICAN CENTURY INTERNATIONAL GROWTH PORTFOLIO:

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

Principal Investment Policies and Risks:

The Portfolio will seek to achieve its investment objective by
investing primarily in equity securities of international companies that the
Sub-advisor believes will increase in value over time. The Sub-advisor uses a
growth investment strategy it developed that looks for companies with earnings
and revenue growth. Ideally, the Sub-advisor looks for companies whose earnings
and revenues are not only growing, but are growing at an accelerating pace.
Accelerating growth is shown, for example, by growth that is faster this quarter
than last or faster this year than the year before. For purposes of the
Portfolio, equity securities include common stocks, preferred stocks and
convertible securities.

The Sub-advisor tracks financial information for thousands of companies
to research and select the stocks it believes will be able to sustain
accelerating growth. This strategy is based on the premise that, over the long
term, the stocks of companies with accelerating earnings and revenues have a
greater-than-average chance to increase in value.

The Sub-advisor recognizes that, in addition to locating strong
companies with accelerating earnings, the allocation of assets among different
countries and regions also is an important factor in managing an international
portfolio. For this reason, the Sub-advisor will consider a number of other
factors in making investment selections, including the prospects for relative
economic growth among countries or regions, economic and political conditions,
expected inflation rates, currency exchange fluctuations and tax considerations.
Under normal conditions, the Portfolio will invest at least 65% of its assets in
equity securities of issuers from at least three countries outside of the United
States. In order to maintain investment flexibility, the Portfolio has not
otherwise established geographic requirements for asset distribution.

While the Portfolio's focus will be on issuers in developed markets,
the Sub-advisor expects to invest to some degree in issuers in developing
countries. The Portfolio may make foreign investments either directly in foreign
securities, or indirectly by purchasing depositary receipts. Securities
purchased in foreign markets may either be traded on foreign securities
exchanges or in the over-the-counter markets.

As with all stocks, the value of the stocks held by the Portfolio can
decrease as well as increase. As a fund investing primarily in equity securities
of foreign issuers, the Portfolio may be subject to a level of risk and share
price fluctuation higher than most funds that invest primarily in domestic
equities. Foreign companies may be subject to greater economic risks than
domestic companies, and foreign securities are subject to certain risks relating
to political, regulatory and market structures and events that domestic
securities are not subject to. To the extent the Portfolio invests in securities
of issuers in developing counties, the Portfolio may be subject to even greater
levels of risk and share price fluctuation.

Other Investments:

Securities of U.S. issuers may be included in the Portfolio from time
to time. The Portfolio also may invest in bonds, notes and debt securities of
companies and obligations of domestic or foreign governments and their agencies.
The Portfolio will limit its purchases of debt securities to investment grade
obligations. The Portfolio may enter into non-leveraged stock index futures
contracts and may make short sales "against the box."

Derivative Securities. The Portfolio may invest in derivative
securities. Certain of these derivative securities may be described as
"index/structured" securities, which are securities whose value or performance
is linked to other equity securities (as in the case of depositary receipts),
currencies, interest rates, securities indices or other financial indicators
("reference indices"). The Portfolio may not invest in a derivative security
unless the reference index or the instrument to which it relates is an eligible
investment for the Portfolio. For example, a security whose underlying value is
linked to the price of oil would not be a permissible investment because the
Portfolio may not invest in oil and gas leases or futures. The Portfolio may
make short sales "against the box."

Forward Currency Exchange Contracts. As a fund investing primarily in
foreign securities, the value of the Portfolio will be affected by changes in
the exchange rates between foreign currencies and the U.S. dollar. To protect
against adverse movements in exchange rates, the Portfolio may, for hedging
purposes only, enter into forward foreign currency exchange contracts. The
Portfolio may enter into a forward contract to "lock-in" an exchange rate for a
specific purchase or sale of a security. Less frequently, the Portfolio may
enter into a forward contract to seek to protect its holdings in a particular
currency from a decline in that currency. Predicting the relative future values
of currencies is very difficult, and there is no assurance that any attempt to
reduce the risk of adverse currency movements through the use of forward
contracts will be successful.

Indirect Foreign Investments. The Portfolio may invest up to 10% of its
assets in certain foreign countries indirectly through investment funds and
registered investment companies that invest in those countries. If the Portfolio
invests in investment companies, it will bear its proportionate share of the
costs incurred by such companies, including any investment advisory fees.

Additional information about the securities that the Portfolio may
invest in and their risks is included below under "Certain Risk Factors and
Investment Methods."

Temporary Investments. Under exceptional market or economic conditions,
the Portfolio may temporarily invest all or a substantial portion of its assets
in cash or investment-grade short-term securities. While the Portfolio is in a
defensive position, the ability to achieve its investment objective of capital
growth may be limited.

<PAGE>

AST AMERICAN CENTURY INTERNATIONAL GROWTH PORTFOLIO II:

The investment objective, policies and risks of the Portfolio (formerly, the AST
T. Rowe Price International Equity Portfolio) are substantially identical to
those of the AST American Century International Growth Portfolio as described
immediately above.

<PAGE>

AST JANUS SMALL-CAP GROWTH PORTFOLIO:

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

Principal Investment Policies and Risks:

The Portfolio pursues its objective by normally investing at least 65%
of its total assets in the common stocks of small-sized companies. For purposes
of the Portfolio, small-sized companies are those that have market
capitalizations of less than $1.5 billion or annual gross revenues of less than
$500 million. To a lesser extent, the Portfolio may also invest in stocks of
larger companies with potential for capital growth.

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. As a Portfolio that invests primarily in smaller or newer issuers,
the Portfolio may be subject to greater risk of loss and share price fluctuation
than funds investing primarily in larger or more established issuers. Smaller
companies are more likely to realize substantial growth as well as suffer
significant losses than larger issuers. Smaller 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 products or
services for which there are not yet, and may never be, established markets. In
addition, such companies may be subject to intense competition from larger
competitors, and may have more limited trading markets than the markets for
securities of larger issuers.

While the Sub-advisor tries to reduce the risk of the Portfolio by
diversifying its assets among issuers (so that the effect of any single holding
is reduced), and by not concentrating its assets in any particular industry,
there is no assurance that these effort will be successful in reducing the risks
to which the Portfolio is subject.

The Portfolio generally intends to purchase securities for long-term
investment rather than short-term gains. However, short-term transactions may
occur as the result of liquidity needs, securities having reached a desired
price or yield, anticipated changes in interest rates or the credit standing of
an issuer, or by reason of economic or other developments not foreseen at the
time the investment was made. 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.

Special Situations. 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
increase in value due to a specific development with respect to that issuer.
Developments creating a special situation might include 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.

Other Investments:

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 is subject to the following
percentage limitations on investing in certain types of debt securities:

- -- 35% of its assets in bonds rated below investment grade by the primary
rating agencies ("junk" bonds).

- -- 25% of its assets in mortgage- and asset-backed securities.

- -- 10% of its assets in zero coupon, pay-in-kind and step coupon securities
(securities that do not, or may not under certain circumstances, make
regular interest payments).

The Portfolio may make short sales "against the box." In addition, the Portfolio
may invest in the following types of securities and engage in the following
investment techniques:

Index/structured Securities. 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.

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, or may invest through depositary
receipts or passive foreign investment companies. Generally, the same criteria
are used to select foreign securities as domestic securities. The Sub-advisor
seeks companies that meet these criteria regardless of country of organization
or principal business activity. However, certain factors such as expected
inflation and currency exchange rates, government policies affecting businesses,
and a country's prospects for economic growth may warrant consideration in
selecting foreign securities.

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, currency exchange rates or interest rates. To a
limited extent, the Portfolio may also use derivative instruments for
non-hedging purposes such as seeking to increase income.

For more information on the types of securities other than common
stocks in which the Portfolio may invest, see this Prospectus under "Certain
Risk Factors and Investment Methods."

Temporary Investments. When the Sub-advisor believes that market
conditions are not favorable for profitable investing or when the Sub-advisor is
otherwise unable to locate favorable investment opportunities, 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 Portfolio's cash and similar investments
may include high-grade commercial paper, certificates of deposit, repurchase
agreements and money market funds managed by the Sub-advisor. While the
Portfolio is in a defensive position, the opportunity to achieve its investment
objective of capital growth will be limited.

<PAGE>

AST NEUBERGER BERMAN MID-CAP VALUE PORTFOLIO:

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

Principal Investment Policies and Risks:

To pursue its objective, the Portfolio primarily invests in the common
stocks of mid-cap companies. Some of the Portfolio's assets may be invested in
the securities of large-cap companies as well as in small-cap companies. The
Portfolio seeks to reduce risk by diversifying among many companies and
industries.

Under the Portfolio's value-oriented investment approach, the
Sub-advisor looks for well-managed companies whose stock prices are undervalued
and that may rise in price before other investors realize their worth. Fund
managers may identify value stocks in several ways, including based on earnings,
book value or other financial measures. Factors that the Sub-advisor may use to
identify these companies include strong fundamentals, including a low
price-to-earnings ratio, consistent cash flow, and a sound track record through
all phases of the market cycle.

The Sub-advisor may also look for other characteristics in a company,
such as a strong position relative to competitors, a high level of stock
ownership among management, or a recent sharp decline in stock price that
appears to be the result of a short-term market overreaction to negative news.

The Sub-advisor generally considers selling a stock when it reaches a
target price, when it fails to perform as expected, or when other opportunities
appear more attractive.

As a fund that invests primarily in mid-cap companies, the Portfolio's
risk and share price fluctuation can be expected to be more than that of many
funds investing primarily in large-cap companies, but less than that of many
funds investing primarily in small-cap companies. Mid-cap stocks may fluctuate
more widely in price than the market as a whole, may underperform other types of
stocks when the market or the economy is not robust, or fall in price or be
difficult to sell during market downturns. While value investing historically
has involved less risk than investing in growth companies, the stocks purchased
by the Portfolio will remain undervalued during a short or extended period of
time. This may happen because value stocks as a category lose favor with
investors compared to growth stocks, or because the Sub-advisor failed to
anticipate which stocks or industries would benefit from changing market or
economic conditions.

Other Investments:

Although equity securities are normally the Portfolio's primary
investment, it may invest in preferred stocks and convertible securities, as
well as the types of securities described below. Additional information about
these investments and the special risk factors that apply to them is included in
this Prospectus under "Certain Risk Factors and Investment Methods."

Fixed Income Securities. The Portfolio may invest up to 35% of its
total assets, measured at the time of investment, in fixed income or debt
securities. The Portfolio may invest up to 15% of its total assets, measured at
the time of investment, in debt securities that are rated below investment grade
or comparable unrated securities. There is no minimum rating on the fixed income
securities in which the Portfolio may invest.

Foreign Securities. The Portfolio may invest up to 10% of the value of
its total assets, measured at the time of investment, in equity and debt
securities that are denominated in foreign currencies. There is no limitation on
the percentage of the Portfolio's assets that may be invested in securities of
foreign companies that are denominated in U.S. dollars. In addition, the
Portfolio may enter into foreign currency transactions, including forward
foreign currency contracts and options on foreign currencies, to manage currency
risks, to facilitate transactions in foreign securities, and to repatriate
dividend or interest income received in foreign currencies.

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, and may purchase call
options in related closing transactions. The value of securities against which
options will be written will not exceed 10% of the Portfolio's net assets.

Temporary Investments. When the Portfolio anticipates unusual market or
other conditions, it may temporarily depart from its objective of capital growth
and invest substantially in high-quality short-term investments. This could help
the Portfolio avoid losses but may mean lost opportunities.

<PAGE>

AST ALGER ALL-CAP GROWTH PORTFOLIO:

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

Principal Investment Policies and Risks:

The Portfolio invests primarily in equity securities, such as common or
preferred stocks, that are listed on U.S. exchanges or in the over-the-counter
market. The Portfolio may invest in the equity securities of companies of all
sizes, and may emphasize either larger or smaller companies at a given time
based on the Sub-advisor's assessment of particular companies and market
conditions.

The Portfolio invests primarily in growth stocks. The Sub-advisor
believes that these stocks are those of two types of companies:

As with any fund investing primarily in equity securities, the value of
the securities held by the Portfolio may decline. These declines can be
substantial. In addition, the growth stocks in which the Portfolio invests
primarily tend to fluctuate in price more than other types of stocks. Prices of
growth stocks tend to be higher in relation to their companies' earnings, and
may be more sensitive to market, political and economic developments than other
stocks. The Portfolio's level of risk will vary based upon the size of the
companies it invests in at a given time. To the extent that the Portfolio
emphasizes small-cap stocks, it will be subject to a level of risk higher than a
fund investing primarily in more conservative "large-cap" stocks.

Other Investments:

In addition to investing in common and preferred stocks, the Portfolio
may invest in securities convertible into or exchangeable for equity securities,
including warrants and rights. The Portfolio may invest up to 20% of its total
assets in foreign securities. (American Depositary Receipts or other U.S. dollar
denominated securities of foreign issuers are not subject to the 20%
limitation.)

The Fund may purchase put and call options and write (sell) put and
covered call options on securities and securities indices to increase gain or to
hedge against the risk of unfavorable price movements. However, the Sub-advisor
does not currently intend to rely on these option strategies extensively, if at
all. The Portfolio may purchase and sell stock index futures contracts and
options on stock index futures contracts. The Portfolio may sell securities
"short against the box."

An additional discussion of these types of investments and their risks
is included in this Prospectus under "Certain Risk Factors and Investment
Methods."

Temporary Investments. The Portfolio may invest up to 100% of its
assets in cash, commercial paper, high-grade bonds or cash equivalents for
temporary defensive reasons if the Sub-advisor believes that adverse market or
other conditions warrant. This is to attempt to protect the Portfolio from a
temporary unacceptable risk of loss. However, while the Portfolio is in a
defensive position, the opportunity to achieve its investment objective of
long-term capital growth will be limited.

<PAGE>

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.

Principal Investment Policies and Risks:

The Portfolio will pursue its objective by investing primarily in
common stocks. Common stock investments will be in 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. The Sub-advisor generally takes a "bottom up" approach to choosing
investments for the Portfolio. In other words, the Sub-advisor seeks to identify
individual companies with earnings growth potential that may not be recognized
by the market at large.

Because the Portfolio invests a substantial portion (or all) of its
assets in stocks, the Portfolio is subject to the risks associated with stock
investments, and the Portfolio's share price therefore may fluctuate
substantially. This is true despite the Portfolio's focus on the stocks of
larger more-established companies. The Portfolio's share price will be affected
by changes in the stock markets generally, and factors specific to a company or
an industry will affect the prices of particular stocks held by the Portfolio
(for example, poor earnings, loss of major customers, major litigation against
an issuer, or changes in government regulations affecting an industry). Because
of the types of securities it invests in, the Portfolio is designed for those
who are investing for the long term.

Special Situations. 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.

Other Investments:

Although the Sub-advisor expects to invest primarily in equity securities,
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. The Portfolio
is subject to the following percentage limitations on investing in certain types
of debt securities:

-- 35% of its assets in bonds rated below investment grade ("junk" bonds).
-- 25% of its assets in mortgage- and asset-backed securities.
-- 10% of its assets in zero coupon, pay-in-kind and step coupon
securities (securities that do not, or may not under certain circumstances, make
regular interest payments).

The Portfolio may make short sales "against the box." In addition, the Portfolio
may invest in the following types of securities and engage in the following
investment techniques:

Foreign Securities. The Portfolio may also purchase securities of
foreign issuers, including foreign equity and debt securities and depositary
receipts. Foreign securities are selected primarily on a stock-by-stock basis
without regard to any defined allocation among countries or geographic regions.
No more than 25% of the Portfolio's assets may be invested in foreign securities
denominated in foreign currencies and not publicly traded in the United States.

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 income. The Portfolio may also
use a variety of currency hedging techniques, including forward foreign currency
exchange contracts, to manage exchange rate risk with respect to investments
exposed to foreign currency fluctuations.

For more information on the types of securities other than common
stocks in which the Portfolio may invest, see this Prospectus under "Certain
Risk Factors and Investment Methods."

Temporary Investments. 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. Cash and similar investments
(whether made for defensive purposes or to receive a return on idle cash) will
include high-grade commercial paper, certificates of deposit, repurchase
agreements and money market funds managed by the Sub-advisor. While the
Portfolio is in a defensive position, the opportunity to achieve its investment
objective of capital growth will be limited.

<PAGE>

AST INVESCO EQUITY INCOME PORTFOLIO:

Investment Objective: The investment objective of the Portfolio is to seek
capital growth and current income while following sound investment practices.

Principal Investment Policies and Risks:

The Portfolio seeks to achieve its objective by investing in securities
that are expected to produce relatively high levels of income and consistent,
stable returns. The Portfolio normally will invest at least 65% of its assets in
dividend-paying common and preferred stocks of domestic and foreign issuers. Up
to 30% of the Portfolio's assets may be invested in equity securities that do
not pay regular dividends. In addition, the Portfolio normally will have some
portion of its assets invested in debt securities or convertible bonds. The
Portfolio may invest up to 25% of its total assets in foreign securities,
including securities of issuers in countries considered to be developing. These
foreign investments may serve to increase the overall risks of the Portfolio.

The Portfolio's investments in common stocks may, of course, decline in
value, which will result in declines in the Portfolio's share price. Such
declines could be substantial. To minimize the risk this presents, the
Sub-advisor 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. In light of the Portfolio's focus on income producing stocks, its
risk and share price fluctuation (and potential for gain) may be less than many
other stock funds.

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 or Moody's
Investors Services, Inc., or equivalent unrated debt securities ("junk bonds").

In order to decrease its risk in investing in debt securities, the
Portfolio will invest no more than 15% of its assets in junk bonds, 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. 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 under "Certain
Risk Factors and Investment Methods."

Temporary Investments:

In periods of uncertain market and economic conditions, the Portfolio
may assume a defensive position with up to 100% of its assets temporarily
invested in high quality corporate bonds or notes or government securities, or
held in cash. While the Portfolio is in a defensive position, the opportunity to
achieve its investment objective may be limited.

<PAGE>

AST T. ROWE PRICE GLOBAL BOND PORTFOLIO:

Investment Objective: The investment objective of the Portfolio is to provide
high current income and capital growth by investing in high-quality, foreign and
U.S. government bonds.

Principal Investment Policies and Risks:

To achieve its objectives, the Portfolio will invest at least 65% of
its total assets in bonds issued or guaranteed by the U.S. or foreign
governments or their agencies and by foreign authorities, provinces and
municipalities. Corporate bonds of U.S. and foreign issuers may also be
purchased. The Portfolio 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 Sub-advisor believes that the currency
risk can be minimized through hedging.

Although the Portfolio expects to maintain an intermediate-to-long
weighted average maturity, there are no maturity restrictions on the overall
portfolio or on individual securities. The Portfolio may and frequently does
engage in foreign currency transactions such as forward foreign currency
exchange contracts, hedging its foreign currency exposure back to the dollar or
against other foreign currencies ("cross-hedging"). The Sub-advisor also
attempts to reduce currency risks through diversification among foreign
securities and active management of currency exposures.

The Portfolio may also invest up to 20% of its assets in the aggregate
in below investment-grade, high-risk bonds ("junk bonds") and emerging market
bonds. Some emerging market bonds, such as Brady Bonds, may be denominated in
U.S. dollars.

Like any fixed income fund, the value of the Portfolio will fluctuate
in response to changes in market interest rates and the credit quality of
particular companies. International fixed income investing, however, involves
additional risks that can increase the potential for losses. These additional
risks include varying stages of economic and political development of foreign
countries, differing regulatory and accounting standards in non-U.S. markets,
and higher transaction costs. Because a substantial portion of the Portfolio's
investments are denominated in foreign currencies, exchange rates are also
likely to have a significant impact on total Portfolio performance. For example,
a rise in the U.S. dollar's value relative to the Japanese yen will decrease the
U.S. dollar value of a Japanese bond held in the Portfolio, even though the
price of that bond in yen remains unchanged. Therefore, because of these
currency risks and the risks of investing in foreign securities generally, the
Portfolio will involve a greater degree of risk and share price fluctuation than
a fund investing primarily in domestic fixed income securities, but ordinarily
will involve less risk than a fund investing exclusively in foreign fixed income
securities. In addition, the Portfolio's focus on longer maturity bonds will
tend to cause greater fluctuations in value when interest rates change.

Types of Debt Securities. The Portfolio's investments in debt
securities may include securities issued or guaranteed by the U.S. and foreign
governments, their agencies, instrumentalities or political subdivisions,
securities issued or guaranteed by supranational organizations (e.g., European
Investment Bank, InterAmerican Development Bank or the World Bank), bank or bank
holding company securities, foreign and domestic corporate debt securities, and
commercial paper.

The Portfolio may invest in zero coupon securities, which are
securities that are purchased at a discount from their face value, but that do
not make cash interest payments. Zero coupon securities are subject to greater
fluctuation in market value as a result of changing interest rates than debt
obligations that make current cash interest payments.

The Portfolio may invest in Brady Bonds, which are used as a means of
restructuring the external debt burden of certain emerging countries. Even if
the bonds are collateralized, they are often considered speculative investments
because of the country's credit history or other factors. 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 Trust's expenses, shareholders will also indirectly bear similar
expenses of such trusts.

The Portfolio from time to time may invest in collateralized mortgage
obligations, asset-backed bonds and debt securities convertible into equities.

Nondiversified Investment Company. The Portfolio intends to select its
investments from a number of country and market sectors, and intends to have
investments in securities of issuers from a minimum of three different countries
(including the United States). However, the Portfolio is considered a
"nondiversified" investment company for purposes of the Investment Company Act
of 1940. As such, 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, except with respect to certain short-term investments. As a
nondiversified fund, a price decline in any one of the Portfolio's holdings may
have a greater effect on the Portfolio's value than on the value of a fund that
is more broadly diversified.

Other Investments:

The Portfolio may buy and sell futures contracts (and related options)
for a number of reasons including: to manage exposure to changes in interest
rates, securities prices and currency exchange rates; as an efficient means of
adjusting overall exposure to certain markets; to earn income; to protect the
value of portfolio securities; and to adjust the portfolio's duration. The
Portfolio may purchase or write call and put options on securities, financial
indices, and foreign currencies. The Portfolio may invest up to 10% of its total
assets in hybrid instruments, which combine the characteristics of futures,
options and securities.

Additional information on the securities in which the Portfolio may
invest and their risks in included below under "Certain Risk Factors and
Investment Methods."

Temporary Investments. To protect against adverse movements of interest
rates, the Portfolio may invest without limit in short-term obligations
denominated in U.S. and foreign currencies such as certain bank obligations,
commercial paper, short-term government and corporate obligations, repurchase
agreements and money market mutual funds managed by the Sub-advisor. Cash
reserves also provide flexibility in meeting redemptions and paying expenses.
While the Portfolio is in a defensive position, the opportunity to achieve its
investment objective of high current income and capital growth may be limited.

<PAGE>

PORTFOLIO TURNOVER:

Each Portfolio may sell its portfolio securities, regardless of the
length of time that they have been held, if the Sub-advisor and/or the
Investment Manager determines that it would be in the Portfolio's best interest
to do so. It may be appropriate to buy or sell portfolio securities due to
economic, market, or other factors that are not within the Sub-advisor's or
Investment Manager's control. Such transactions will increase a Fund's
"portfolio turnover." A 100% portfolio turnover rate would occur if all of the
securities in a portfolio of investments were replaced during a given period.

Although turnover rates may vary substantially from year to year, it is
anticipated that the following Portfolios regularly may regularly have annual
rates of turnover exceeding 100%:

AST American Century International Growth Portfolio
AST American Century International Growth Portfolio II
AST Janus Small-Cap Growth Portfolio
AST Neuberger Berman Mid-Cap Value Portfolio
AST JanCap Growth Portfolio
AST T. Rowe Price Global Bond Portfolio

A high rate of portfolio turnover involves correspondingly higher
brokerage commission expenses and other transaction costs, which are borne by a
Portfolio and will reduce its performance.

NET ASSET VALUE:

The net asset value per share ("NAV") of each Portfolio is determined
as of the close of the New York Stock Exchange (the "NYSE") (normally 4:00 p.m.
Eastern Time) on each day that the NYSE is open for business. NAV is determined
by dividing the value of a Portfolio's total assets, less any liabilities, by
the number of total shares of that Portfolio outstanding. In general, the assets
of each Portfolio are valued on the basis of market quotations. However, in
certain circumstances where market quotations are not readily available or are
believed to be inaccurate, assets are valued by methods that are believed to
accurately reflect their fair value. Because NAV is calculated and purchases may
be made only on business days, and because securities traded on foreign
exchanges may trade on other days, the value of a Portfolio's investments may
change on days when shares cannot be purchased or redeemed.

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 investing
assets attributable to variable annuity contracts and variable life insurance
policies ("contractholders"), 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 to be effected on
that day under the variable annuity contracts and variable life insurance
policies. Orders are effected on days on which the NYSE is open for trading.
Orders received before 4:00 P.M. Eastern time are effected at the NAV 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 NAV calculated the next business day. Payment
for redemptions will be made 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. However, 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. Please refer to
the prospectuses for the variable annuity contracts and variable insurance
policies for further information on these fees.

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. The profit sharing plan covering employees of
ASLAC and its affiliates, which is a retirement plan qualified under Section
401(a) of the Internal Revenue Code of 1986, as amended, also may directly own
shares of the Trust. Certain conflicts of interest may arise as a result of
investment in the Trust by various insurance companies for the benefit of their
contractholders and by various qualified plans. These conflicts could arise
because of differences in the tax treatment of the various investors, because of
actions of the Participating Insurance Companies and/or the qualified plans, or
other reasons. The Trust does not currently expect that any material conflicts
of interest will arise. Nevertheless, the Trustees intend to monitor events in
order to identify any material irreconcilable conflicts and to determine what
action, if any, should be taken in response to such conflicts. Should any
conflict arise that would require a substantial amount of assets to be withdrawn
from the Trust, orderly portfolio management could be disrupted.

MANAGEMENT OF THE TRUST:

Investment Manager: American Skandia Investment Services, Incorporated
("ASISI"), One Corporate Drive, Shelton, Connecticut, acts as Investment Manager
to the Trust. ASISI has served as Investment Manager since 1992, and currently

(including the Portfolios of the Trust). ASISI is an indirect wholly-owned
subsidiary of Skandia Insurance Company Ltd. ("Skandia"). Skandia is a Swedish
company that owns, directly or indirectly, a number of insurance companies in
many countries. The predecessor to Skandia commenced operations in 1855.

The Trust's Investment Management Agreements with ASISI (the
"Management Agreements") provide that ASISI will furnish each applicable
Portfolio with investment advice and administrative services 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 Sub-advisors to
conduct the investment programs of each Portfolio, including the purchase,
retention and sale of portfolio securities. The Investment Manager is
responsible for monitoring the activities of the Sub-advisors and reporting on
such activities to the Trustees. The Investment Manager must also provide, or
obtain and supervise, the executive, administrative, accounting, custody,
transfer agent and shareholder servicing services that are deemed advisable by
the Trustees.

The Trust has obtained an exemption from the Securities and Exchange
Commission that permits ASISI, subject to approval by the Board of Trustees of
the Trust, to change sub-advisors for a Portfolio and to enter into new
sub-advisory agreements, without obtaining shareholder approval of the changes.
This exemption (which is similar to exemptions granted to other investment
companies that are organized in a similar manner as the Trust) is intended to
facilitate the efficient supervision and management of the sub-advisors by ASISI
and the Trustees.

Fees and Expenses:

Investment Management Fees. ASISI receives a fee, payable each month,
for the performance of its services. ASISI pays each Sub-advisor a portion of
such fee for the performance of the Sub-advisory services at no additional cost
to any Portfolio. The Investment Management fee for each Portfolio will differ,
reflecting the differing objectives, policies and restrictions of each
Portfolio. Each Portfolio's fee is accrued daily for the purposes of determining
the sale and redemption price of the Portfolio's shares. The fees paid to ASISI
for the fiscal year ended December 31, 1999 by each Portfolio that was in
operation for that entire fiscal year, stated as a percentage of the Portfolio's
average daily net assets, were as follows:

<TABLE>
<CAPTION>
Portfolio: Annual Rate:

<S> <C>
AST American Century International Growth Portfolio: 1.00%
AST American Century International Growth Portfolio II: 1.00%
AST Janus Small-Cap Growth Portfolio: 0.90%
AST Neuberger Berman Mid-Cap Value Portfolio: 0.82%
AST JanCap Growth Portfolio: 0.87%
AST INVESCO Equity Income Portfolio: 0.75%
AST T. Rowe Price Global Bond Portfolio: 0.80%
</TABLE>

The investment management fee rate for the AST Alger All-Cap Growth
Portfolio, which commenced operations in January 2000, is an annual rate of .95%
of the average daily net assets of the Portfolio.

For more information about investment management fees, including
voluntary fee waivers and the fee rates applicable at various asset levels, and
the fees payable by ASISI to each of the Sub-advisors, please see the Trust's
SAI under "Investment Advisory and Other Services."

Other Expenses. In addition to Investment Management fees, each
Portfolio pays other expenses, including costs incurred in connection with the
maintenance of its securities law registrations, printing and mailing
prospectuses and statements of additional information to shareholders, certain
office and financial accounting services, taxes or governmental fees, brokerage
commissions, custodial, transfer and shareholder servicing agent costs, expenses
of outside counsel and independent accountants, preparation of shareholder
reports and expenses of trustee and shareholder meetings. The Trust may also pay
Participating Insurance Companies for printing and delivery of certain documents
(including prospectuses, semi-annual and annual reports and any proxy materials)
to holders of variable annuity contracts and variable life insurance policies
whose assets are invested in the Trust. Expenses not directly attributable to
any specific Portfolio or Portfolios are allocated on the basis of the net
assets of the Portfolios.

Distribution Plan. The Trust has adopted a Distribution Plan (the
"Distribution Plan") under Rule 12b-1 under the Investment Company Act of 1940
to permit American Skandia Marketing, Inc. ("ASM"), an affiliate of ASISI, to
receive brokerage commissions in connection with purchases and sales of
securities held by the Portfolios, and to use these commissions to promote the
sale of shares of the Portfolios. Under the Distribution Plan, transactions for
the purchase and sale of securities for a Portfolio may be directed to certain
brokers for execution ("clearing brokers") who have agreed to pay part of the
brokerage commissions received on these transactions to ASM for "introducing"
transactions to the clearing broker. In turn, ASM will use the brokerage
commissions received as an introducing broker to pay various
distribution-related expenses, such as advertising, printing of sales materials,
and payments to dealers. No Portfolio will pay any new fees or charges resulting
from the Distribution Plan, nor is it expected that the brokerage commissions
paid by a Portfolio will increase as the result of implementation of the
Distribution Plan.

TAX MATTERS:

Each Portfolio intends to distribute substantially all its net
investment income. Dividends from investment income are expected to be declared
and distributed annually (except in the case of the AST Money Market Portfolio,
where dividends will be declared daily and paid monthly), although the Trustees
of the Trust may decide to declare dividends at other intervals. Similarly, any
net realized long- and short-term capital gains of each Portfolio will be
declared and distributed at least annually either during or after the close of
the Portfolio's fiscal year. Distributions will be made to the various separate
accounts of the Participating Insurance Companies and to qualified plans (not to
holders of variable insurance contracts or to plan participants) in the form of
additional shares (not in cash). The result is that the investment performance
of the Portfolios, either in the form of dividends or capital gains, will be
reflected in the value of the variable contracts or the qualified plans.

Holders of variable annuity contracts or variable life insurance
policies should consult the prospectuses of their respective contracts or
policies for information on the federal income tax consequences to such holders,
and plan participants should consult any applicable plan documents for
information on the federal income tax consequences to such participants. In
addition, variable contract owners and qualified plan participants may wish to
consult with their own tax advisors as to the tax consequences of investments in
the Trust, including the application of state and local taxes.

investor would have earned or lost in a Portfolio. The information has been
audited by Deloitte & Touche LLP, the Trust's independent auditors. The report
of the independent auditors, along with the Portfolios' financial statements,
are included in the annual reports of the separate accounts funding the variable
annuity contracts and variable life insurance policies, which are available
without charge upon request to the Trust at One Corporate Drive, Shelton,
Connecticut or by calling (800) 752-6342. No financial information is included

CERTAIN RISK FACTORS AND INVESTMENT METHODS:

The following is a description of certain securities and investment
methods that the Portfolios may invest in or use, and certain of the risks
associated with such securities and investment methods. The primary investment
focus of each Portfolio is described above under "Investment Objective and
Policies" and an investor should refer to that section to obtain information
about each Portfolio. In general, whether a particular Portfolio may invest in a
specific type of security or use an investment method is described above or in
the Company's SAI under "Investment Programs of the Funds." As noted below,
however, certain risk factors and investment methods apply to all or most of the
Portfolios.

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 (sell) call and put options on securities, securities indices and
foreign currencies, enter into futures contracts and use options on futures
contracts, and enter into swap agreements with respect to foreign currencies,
interest rates, and securities indices. In general, derivative instruments are
securities or other instruments whose value is derived from or related to the
value of some other instrument or asset.

There are many types of derivatives and many different ways to use
them. Some derivatives and derivative strategies involve very little risk, while
others can be extremely risky and can lead to losses in excess of the amount
invested in the derivative. A Portfolio may use derivatives to hedge against
changes in interest rates, foreign currency exchange rates or securities prices,
to generate income, as a low cost method of gaining exposure to a particular
securities market without investing directly in those securities, or for other
reasons.

The use of these strategies involves certain special risks, including
the risk that the price movements of derivative instruments will not correspond
exactly with those of the investments from which they are derived. In addition,
strategies involving derivative instruments that are intended to reduce the risk
of loss can also reduce the opportunity for gain. Furthermore, regulatory
requirements for a Portfolio to set aside assets to meet its obligations with
respect to derivatives may result in a Portfolio being unable to purchase or
sell securities when it would otherwise be favorable to do so, or in a Portfolio
needing to sell securities at a disadvantageous time. A Portfolio may also be
unable to close out its derivatives positions when desired. There is no
assurance that a Portfolio will engage in derivative transactions. Certain
derivative instruments and some of their risks are described in more detail
below.

Options. Most of the Portfolios may purchase or write (sell) call or
put options on securities, financial indices or currencies. The purchaser of an
option on a security or currency obtains the right to purchase (in the case of a
call option) or sell (in the case of a put option) the security or currency at a
specified price within a limited period of time. Upon exercise by the purchaser,
the writer (seller) of the option has the obligation to buy or sell the
underlying security at the exercise price. An option on a securities index is
similar to an option on an individual security, except that the value of the
option depends on the value of the securities comprising the index, and all
settlements are made in cash.

A Portfolio will pay a premium to the party writing the option when it
purchases an option. In order for a call option purchased by a Portfolio to be
profitable, the market price of the underlying security must rise sufficiently
above the exercise price to cover the premium and other transaction costs.
Similarly, in order for a put option to be profitable, the market price of the
underlying security must decline sufficiently below the exercise price to cover
the premium and other transaction costs.

Generally, the Portfolios will write call options only if they are
covered (i.e., the Fund owns the security subject to the option or has the right
to acquire it without additional cost). By writing a call option, a Portfolio
assumes the risk that it may be required to deliver a security for a price lower
than its market value at the time the option is exercised. Effectively, a
Portfolio that writes a covered call option gives up the opportunity for gain
above the exercise price should the market price of the underlying security
increase, but retains the risk of loss should the price of the underlying
security decline. A Portfolio will write call options in order to obtain a
return from the premiums received and will retain the premiums whether or not
the options are exercised, which will help offset a decline in the market value
of the underlying securities. A Portfolio that writes a put option likewise
receives a premium, but assumes the risk that it may be required to purchase the
underlying security at a price in excess of its current market value.

A Portfolio may sell an option that it has previously purchased prior
to the purchase or sale of the underlying security. Any such sale would result
in a 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 option. A
Portfolio may terminate an option it has written by entering into a closing
purchase transaction in which it purchases an option of the same series as the
option written.

Futures Contracts and Related Options. Each Portfolio (except AST
Neuberger Berman Mid-Cap Value Portfolio and the AST INVESCO Equity Income
Portfolio) may enter into financial futures contracts and related options. The
seller of a futures contract agrees to sell the securities or currency called
for in the contract and the buyer agrees to buy the securities or currency at a
specified price at a specified future time. Financial futures contracts may
relate to securities indices, interest rates or foreign currencies. Futures
contracts are usually settled through net cash payments rather than through
actual delivery of the securities underlying the contract. For instance, in a
stock index futures contract, the 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 when the contract expires and the price specified
in the contract. A Portfolio may use futures contracts to hedge against
movements in securities prices, interest rates or currency exchange rates, or as
an efficient way to gain exposure to these markets.

An option on a futures contract gives the purchaser the right, in
return for the premium paid, to assume a position in the contract at the
exercise price at any time during the life of the option. The writer of the
option is required upon exercise to assume the opposite position.

Under regulations of the Commodity Futures Trading Commission ("CFTC"),
no Portfolio will:

(i) 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 each Portfolio's net assets; and

(ii) enter into any futures contracts if the aggregate amount of that
Portfolio's commitments under outstanding futures contracts positions would
exceed the market value of its total assets.

Risks of Options and Futures Contracts. Options and futures contracts
can be highly volatile and their use can reduce a Portfolio's performance.
Successful use of these strategies requires the ability to predict future
movements in securities prices, interest rates, currency exchange rates, and
other economic factors. If a Sub-advisor seeks to protect a Portfolio against
potential adverse movements in the relevant financial markets using these
instruments, and such markets do not move in the predicted direction, the
Portfolio could be left in a less favorable position than if such strategies had
not been used. A Portfolio's potential losses from the use of futures extends
beyond its initial investment in such contracts.

Among the other risks inherent in the use of options and futures are
(a) the risk of imperfect correlation between the price of options and futures
and the prices of the securities or currencies to which they relate, (b) the
fact that skills needed to use these strategies are different from those needed
to select portfolio securities and (c) the possible need to defer closing out
certain positions to avoid adverse tax consequences. With respect to options on
stock indices and stock index futures, the risk of imperfect correlation
increases the more the holdings of the Portfolio differ from the composition of
the relevant index. These instruments may not have a liquid secondary market.
Option positions established in the over-the-counter market may be particularly
illiquid and may also involve the risk that the other party to the transaction
fails to meet its obligations.

FOREIGN SECURITIES:

Investments in securities of foreign issuers may involve risks that are
not present with domestic investments. While investments in foreign securities
can reduce risk by providing further diversification, such investments involve
"sovereign risks" in addition to the credit and market risks to which securities
generally are subject. Sovereign risks 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. 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. In some
countries, there may also be the possibility of expropriation or confiscatory
taxation, difficulty in enforcing contractual and other obligations, political
or social instability or revolution, or diplomatic developments that could
affect investments in those countries.

Securities of some foreign issuers are less liquid and their prices are
more volatile than securities of comparable domestic issuers. Further, it may be
more difficult for the Trust's agents to keep currently informed about corporate
actions and decisions that may affect the price of portfolio securities.
Brokerage commissions on foreign securities exchanges, which may be fixed, may
be higher than in the United States. Settlement of transactions in some foreign
markets may be less frequent or less reliable than in the United States, which
could affect the liquidity of investments. For example, securities that are
traded in foreign markets may trade on days (such as Saturday or Holidays) when
a Portfolio does not compute its price or accept purchase or redemption orders.
As a result, a shareholder may not be able to act on developments taking place
in foreign countries as they occur.

American Depositary Receipts ("ADRs"), European Depositary Receipts
("EDRs"), Global Depositary Receipts ("GDRs"), and International Depositary
Receipts ("IDRs"). ADRs are U.S. dollar-denominated receipts generally issued by
a domestic bank evidencing its ownership of a security of a foreign issuer. ADRs
generally are publicly traded in the United States. ADRs are subject to many of
the same risks as direct investments in foreign securities, although ownership
of ADRs may reduce or eliminate certain risks associated with holding assets in
foreign countries, such as the risk of expropriation. EDRs, GDRs and IDRs are
receipts similar to ADRs that typically trade in countries other than the United
States.

Depositary receipts may be issued as sponsored or unsponsored programs.
In sponsored programs, the issuer makes arrangements to have its securities
traded as depositary receipts. In unsponsored programs, the issuer may not be
directly involved in 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.

Developing Countries. Although none of the Portfolios invest primarily
in securities of issuers in developing countries, many of the Funds may invest
in these securities to some degree. Many of the risks described above with
respect to investing in foreign issuers are accentuated when the issuers are
located in developing countries. Developing countries may be politically and/or
economically unstable, and the securities markets in those countries may be less
liquid or subject to inadequate government regulation and supervision.
Developing countries have often experienced high rates of inflation or sharply
devalued their currencies against the U.S. dollar, causing the value of
investments in companies located in these countries to decline. Securities of
issuers in developing countries may be more volatile and, in the case of debt
securities, more uncertain as to payment of interest and principal. Investments
in developing countries may include securities created through the Brady Plan,
under which certain heavily-indebted countries have restructured their bank debt
into bonds.

Currency Fluctuations. Investments in foreign securities may be
denominated in foreign currencies. The value of a Portfolio's investments
denominated in foreign currencies may be affected, favorably or unfavorably, by
exchange rates and exchange control regulations. A Portfolio's share price may,
therefore, also be affected by changes in currency exchange rates. Foreign
currency exchange rates generally are determined by the forces of supply and
demand in foreign exchange markets, including perceptions of the relative merits
of investment in different countries, actual or perceived changes in interest
rates or other complex factors. Currency exchange rates also can be affected
unpredictably by the intervention or the failure to intervene by U.S. or foreign
governments or central banks, 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.

While the introduction of a single currency, the euro, on January 1,
1999 for participating nations in the European Economic and Monetary Union
generally occurred without significant market or operational disruption, the
euro still presents certain political and operational uncertainties. These
uncertainties may include political reaction against the euro in participating
nations and operational difficulties as the result of the fact that some
securities still pay dividends and interest in the old currencies. These
uncertainties could cause market disruptions, and could adversely affect the
value of securities held by the Portfolios.

Foreign Currency Transactions. A Portfolio that invests in securities
denominated in foreign currencies will need to engage in foreign currency
exchange transactions. Such transactions may occur on a "spot" basis at the
exchange rate prevailing at the time of the transaction. Alternatively, a
Portfolio may enter into forward foreign currency exchange contracts. A forward
contract involves an obligation to purchase or sell a specified currency at a
specified future date at a price set at the time of the contract. A Portfolio
may enter into a forward contract when it wishes to "lock in" the U.S. dollar
price of a security it expects to or is obligated to purchase or sell in the
future. This practice may be referred to as "transaction hedging." In addition,
when a Portfolio's Sub-advisor believes that the currency of a particular
country may suffer or enjoy a significant movement compared to another currency,
the Portfolio may enter into a forward contract to sell or buy the first foreign
currency (or a currency that acts as a proxy for such currency). This practice
may be referred to as "portfolio hedging." In any event, the precise matching of
the forward contract amounts and the value of the securities involved generally
will not be possible. No Portfolio will enter into a forward contract if it
would be obligated to sell an amount of foreign currency in excess of the value
of the Fund's securities or other assets denominated in or exposed to that
currency, or will sell an amount of proxy currency in excess of the value of
securities denominated in or exposed to the related currency. The effect of
entering into a forward contract on a Portfolio's share price will be similar to
selling securities denominated in one currency and purchasing securities
denominated in another. Although a forward contract may reduce a Portfolio's
losses on securities denominated in foreign currency, it may also reduce the
potential for gain on the securities if the currency's value moves in a
direction not anticipated by the Sub-advisor. In addition, foreign currency
hedging may entail significant transaction costs.

COMMON AND PREFERRED STOCKS:

Stocks represent shares of ownership in a company. Generally, preferred
stock has a specified dividend and ranks after bonds and before common stocks in
its claim on the company's income for purposes of receiving dividend payments
and on the company's assets in the event of liquidation. (Some of the
Sub-advisors consider preferred stocks to be equity securities for purposes of
the various Portfolios' investment policies and restrictions, while others
consider them fixed income securities.) After other claims are satisfied, common
stockholders participate in company profits on a pro rata basis; profits may be
paid out in dividends or reinvested in the company to help it grow. Increases
and decreases in earnings are usually reflected in a company's stock price, so
common stocks generally have the greatest appreciation and depreciation
potential of all corporate securities.

FIXED INCOME SECURITIES:

Most of the Portfolios, including the Portfolios that invest primarily
in equity securities, may invest to some degree in bonds, notes, debentures and
other obligations of corporations and governments. Fixed-income securities are
generally subject to two kinds of risk: credit risk and market risk. Credit risk
relates to the ability of the issuer to meet interest and principal payments as
they come due. The ratings given a security by Moody's Investors Service, Inc.
("Moody's") and Standard & Poor's Corporation ("S&P"), which are described in
detail in the Appendix to the Company's SAI, provide a generally useful guide as
to such credit risk. The lower the rating, the greater the credit risk the
rating service perceives to exist with respect to the security. Increasing the
amount of Portfolio assets invested in lower-rated securities generally will
increase the Portfolio's income, but also will increase the credit risk to which
the Portfolio is subject. Market risk relates to the fact that the prices of
fixed income securities generally will be affected by changes in the level of
interest rates in the markets generally. An increase in interest rates will tend
to reduce the prices of such securities, while a decline in interest rates will
tend to increase their prices. In general, the longer the maturity or duration
of a fixed income security, the more its value will fluctuate with changes in
interest rates.

Lower-Rated Fixed Income Securities. Lower-rated high-yield bonds
(commonly known as "junk bonds") are those that are rated lower than the four
highest categories by a nationally recognized statistical rating organization
(for example, lower than Baa by Moody's or BBB by S&P), or, if not rated, are of
equivalent investment quality as determined by the Sub-advisor. Lower-rated
bonds are generally considered to be high risk investments as they are subject
to greater credit risk than higher-rated bonds. In addition, the market for
lower-rated bonds may be thinner and less active than the market for
higher-rated bonds, and the prices of lower-rated high-yield bonds may fluctuate
more than the prices of higher-rated bonds, particularly in times of market
stress. Because the risk of default is higher in lower-rated bonds, a
Sub-advisor's research and analysis tend to be very important ingredients in the
selection of these bonds. In addition, the exercise by an issuer of redemption
or call provisions that are common in lower-rated bonds may result in their
replacement by lower yielding bonds.

Bonds rated in the four highest ratings categories are frequently
referred to as "investment grade." However, bonds rated in the fourth category
(Baa or BBB) are considered medium grade and may have speculative
characteristics.

MORTGAGE-BACKED SECURITIES:

Mortgage-backed securities are securities representing interests in
"pools" of mortgage loans on residential or commercial real property and that
generally provide for monthly payments of both interest and principal, in effect
"passing through" monthly payments made by the individual borrowers on the
mortgage loans (net of fees paid to the issuer or guarantor of the securities).
Mortgage-backed securities are frequently issued by U.S. Government agencies or
Government-sponsored enterprises, and payments of interest and principal on
these securities (but not their market prices) may be guaranteed by the full
faith and credit of the U.S. Government or by the agency only, or may be
supported by the issuer's ability to borrow from the U.S. Treasury.
Mortgage-backed securities created by non-governmental issuers may be supported
by various forms of insurance or guarantees.

Like other fixed-income securities, the value of a mortgage-backed
security will generally decline when interest rates rise. However, when interest
rates are declining, their value may not increase as much as other fixed-income
securities, because early repayments of principal on the underlying mortgages
(arising, for example, from sale of the underlying property, refinancing, or
foreclosure) may serve to reduce the remaining life of the security. If a
security has been purchased at a premium, the value of the premium would be lost
in the event of prepayment. Prepayments on some mortgage-backed securities may
necessitate that a Portfolio find other investments, which, because of
intervening market changes, will often offer a lower rate of return. In
addition, the mortgage securities market may be particularly affected by changes
in governmental regulation or tax policies.

Collateralized Mortgage Obligations (CMOs). CMOs are a type of mortgage
pass-through security that are typically issued in multiple series with each
series having a different maturity. Principal and interest payments from the
underlying collateral are first used to pay the principal on the series with the
shortest maturity; in turn, the remaining series are paid in order of their
maturities. Therefore, depending on the type of CMOs in which a Portfolio
invests, the investment may be subject to greater or lesser risk than other
types of mortgage-backed securities.

Stripped Mortgage-Backed Securities. Stripped mortgage-backed
securities are mortgage pass-through securities that have been divided into
interest and principal components. "IOs" (interest only securities) receive the
interest payments on the underlying mortgages while "POs" (principal only
securities) receive the principal payments. The cash flows and yields on IO and
PO classes are extremely sensitive to the rate of principal payments (including
prepayments) on the underlying mortgage loans. If the underlying mortgages
experience higher than anticipated prepayments, an investor in an IO class of a
stripped mortgage-backed security may fail to recoup fully its initial
investment, even if the IO class is highly rated or is derived from a security
guaranteed by the U.S. Government. Conversely, if the underlying mortgage assets
experience slower than anticipated prepayments, the price on a PO class will be
affected more severely than would be the case with a traditional mortgage-backed
security. Unlike other fixed-income and other mortgage-backed securities, the
value of IOs tends to move in the same direction as interest rates.

ASSET-BACKED SECURITIES:

Asset-backed securities conceptually are similar to mortgage
pass-through securities, but they are secured by and payable from payments on
assets such as credit card, automobile or trade loans, rather than mortgages.
The credit quality of these securities depends primarily upon the quality of the
underlying assets and the level of credit support or enhancement provided. In
addition, asset-backed securities involve prepayment risks that are similar in
nature to those of mortgage pass-through securities.

CONVERTIBLE SECURITIES AND WARRANTS:

Certain of the Portfolios may invest in convertible securities.
Convertible securities are bonds, notes, debentures and preferred stocks that
may be converted into or exchanged for shares of common stock. Many convertible
securities are rated below investment grade because they fall below ordinary
debt securities in order of preference or priority on the issuer's balance
sheet. Convertible securities generally participate in the appreciation or
depreciation of the underlying stock into which they are convertible, but to a
lesser degree. Frequently, convertible securities are callable by the issuer,
meaning that the issuer may force conversion before the holder would otherwise
choose.

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 the
warrants. A warrant will expire without value if the rights under such warrant
are not exercised prior to its expiration date.

WHEN-ISSUED, DELAYED-DELIVERY AND FORWARD COMMITMENT TRANSACTIONS:

The Portfolios (other than the AST Alger All-Cap Growth Portfolio) may
purchase securities on a when-issued, delayed-delivery or forward commitment
basis. These transactions generally involve the purchase of a security with
payment and delivery due at some time in the future. A Portfolio does not earn
interest on such securities until settlement and bears the risk of market value
fluctuations in between the purchase and settlement dates. If the seller fails
to complete the sale, the Fund may lose the opportunity to obtain a favorable
price and yield. While the Portfolios will generally engage in such when-issued,
delayed-delivery and forward commitment transactions with the intent of actually
acquiring the securities, a Portfolio may sometimes sell such a security prior
to the settlement date.

Certain Portfolios may also sell securities on a
delayed-delivery or forward commitment basis. If the Portfolio does so, it will
not participate in future gains or losses on the security. If the other party to
such a transaction fails to pay for the securities, the Portfolio could suffer a
loss.

ILLIQUID AND RESTRICTED SECURITIES:

Subject to guidelines adopted by the Trustees of the Trust, each
Portfolio may invest up to 15% of its net assets in illiquid securities.
Illiquid securities are those that, because of the absence of a readily
available market or due to legal or contractual restrictions on resale, cannot
be sold within seven days in the ordinary course of business at approximately
the amount at which the Fund has valued the investment. Therefore, a Portfolio
may find it difficult to sell illiquid securities at the time considered most
advantageous by its Sub-advisor and may incur expenses that would not be
incurred in the sale of securities that were freely marketable.

Certain securities that would otherwise be considered illiquid because
of legal restrictions on resale to the general public may be traded among
qualified institutional buyers under Rule 144A of the Securities Act of 1933.
These Rule 144A securities, and well as commercial paper that is sold in private
placements under Section 4(2) of the Securities Act, may be deemed liquid by the
Portfolio's Sub-advisor under the guidelines adopted by the Trustees of the
Trust. However, the liquidity of a Portfolio's investments in Rule 144A
securities could be impaired if trading does not develop or declines.

REPURCHASE AGREEMENTS:

Each Portfolio may enter into 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. Repurchase agreements must be fully collateralized and can
be entered into only with well-established banks and broker-dealers that have
been deemed creditworthy by the Sub-advisor. Repurchase transactions are
intended to be short-term transactions, usually with the seller repurchasing the
securities within seven days. Repurchase agreements that mature in more than
seven days are subject to a Portfolio's limit on illiquid securities.

A Portfolio that enters into a repurchase agreement may lose money in
the event that the other party defaults on its obligation and the Portfolio is
delayed or prevented from disposing of the collateral. A Portfolio also might
incur a loss if the value of the collateral declines, and it might incur costs
in selling the collateral or asserting its legal rights under the agreement. If
a defaulting seller filed for bankruptcy or became insolvent, disposition of
collateral might be delayed pending court action.

REVERSE REPURCHASE AGREEMENTS:

Certain Portfolios (specifically, the AST Janus Small-Cap Growth
Portfolio, the AST Neuberger Berman Mid-Cap Value Portfolio, and the AST JanCap
Growth Portfolio) may enter into reverse repurchase agreements. In a reverse
repurchase agreement, a Portfolio sells a portfolio instrument and agrees to
repurchase it at an agreed upon date and price, which reflects an effective
interest rate. It may also be viewed as a borrowing of money by the Portfolio
and, like borrowing money, may increase fluctuations in a Portfolio's share
price. When entering into a reverse repurchase agreement, a Portfolio must set
aside on its books cash or other liquid assets in an amount sufficient to meet
its repurchase obligation.

BORROWING:

Each Portfolio may borrow money from banks. 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, such
Portfolio must reduce such borrowings so as to meet the necessary test within
three business days. The AST Neuberger Berman Mid-Cap Value Portfolio) will not
purchase securities when outstanding borrowings are greater than 5% of the
Portfolio's total assets. If a Portfolio borrows money, its share price may
fluctuate more widely until the borrowing is repaid.

<PAGE>

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 has the right 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.

OTHER INVESTMENT COMPANIES:

The Company 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 Sub-advisors may invest Portfolio assets in money
market funds that they advise or in other investment companies. 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.

SHORT SALES "AGAINST THE BOX":

While none of the Portfolios will make short sales generally, the AST
American Century International Growth Portfolio, the AST American Century
International Growth Portfolio II, the AST Janus Small-Cap Growth Portfolio, the
AST JanCap Growth Portfolio, and the AST INVESCO Equity Income Portfolio may
make short sales "against the box." A short sale against the box involves
selling a security that the Portfolio owns, or has the right to obtain without
additional costs, for delivery at a specified date in the future. A Portfolio
may make a short sale against the box to hedge against anticipated declines in
the market price of a portfolio security. If the value of the security sold
short increases instead, the Portfolio loses the opportunity to participate in
the gain.

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 proper functioning of their
respective computer systems. While the Service Providers did not experience any
significant computer malfunctions as a result of such computer systems failing
to recognize dates in the Year 2000 (the "Year 2000 Issue"), it is possible that
such malfunctions still may occur or be discovered. In addition, it is still
possible that the Year 2000 Issue will have an adverse effect on the Portfolios'
investments or on global markets or economies generally. The Investment Manager
and the Trust are continuing to monitor the Year 2000 Issue in an effort to
confirm that no disruptions in the services provided to the Trust take place.
