              DEAR INVESTOR:
 
                We are pleased to present our annual report for the SunAmerica
              Series Trust, one of the underlying trusts for the Polaris and
              PolarisII Variable Annuities from Anchor National Life Insurance
              Company and the Polaris Variable Annuity from First SunAmerica
              Life Insurance Company.
 
                The following is a combined perspective on the U.S. and global
              economies for the one-year reporting period ended November 30,
              1997, from eight of the nine investment managers who manage the
              Polaris portfolios (excluding Wellington Management Company, LLP,
              which manages the portfolios in the Anchor Series Trust, for which
              you will receive a separate and complete report in about one
              month). Also included is a 1998 outlook on the U.S. and global
              markets from the Polaris investment managers.
 
              THE YEAR IN REVIEW
 
              U.S. Economy
 
                Despite the uncertainty that the recent crisis in Asia has
              brought to the U.S. economy, the U.S. remains in a moderate
              growth, low inflationary environment. The consensus view of the
              Polaris investment managers is echoed by Federal Reserve Chairman
              Alan Greenspan, who recently commented on the state of the U.S.
              economy: "Growth appears to have remained robust and inflation
              low, and even falling, despite an ever-tightening labor market."
 
                SunAmerica Asset Management notes that real Gross Domestic
              Product (GDP) growth increased to 3.5% in the third quarter of
              1997, in line with expectations and up from the 3.3% GDP growth in
              the second quarter. The increase in GDP growth reflects very
              strong consumer demand for domestic goods and services, an
              indication of continued strength in the U.S. economy despite a
              widening trade deficit and less inventory building. On the
              inflation front, the Consumer Price Index (CPI) has gone from 2.8%
              to 2.2%, indicating very mild inflation and the smallest growth in
              more than 30 years. SunAmerica Asset Management adds, "As we come
              to the end of the seventh year of this economic recovery,
              inflation appears under control. We are very cognizant of the fear
              of wage inflation, but the latest numbers suggest that wage
              inflation is still running below 3.5%, which is quite acceptable
              for this stage of an economic recovery."
 
              U.S. Stock Market
 
                On December 5, 1996, when Alan Greenspan startled the U.S.
              equity markets with his "irrational exuberance" speech, the Dow
              Jones Industrial Average ("the Dow") stood at 6440. Although the
              equity market had its ups and downs since then, the Dow ended
              November 30, 1997 near 8000 -- up over 20%. The broader Standard &
              Poor's Composite Index of 500 Stocks ("S&P 500") rose an
              impressive 28.59% for the year, marking an unprecedented third
              year of 20%-plus gains. Phoenix Investment Counsel attributes this
              market advance in 1997 to a powerful combination of strong
              corporate profit growth, falling interest rates, and a global
              flight to quality in the aftermath of collapsing Asian-Pacific
              markets.
 
                Despite the U.S. stock market's solid strength, there were
              periods of intense volatility. Putnam Investments notes that the
              first major event of 1997 to impact U.S. financial

              markets was a 25-basis-point increase in interest rates by the
              Federal Reserve in March. In response, U.S. equities gave up
              almost 10% of their market value in just one month.
 
                "The dangers of market timing -- a strategy we studiously
              avoid -- were apparent during this second quarter," says Federated
              Investors. While conventional wisdom in early April was that the
              U.S. economy was too strong and that the Fed would be forced to
              raise interest rates again, what followed instead was a quick
              market recovery. The U.S. equity market rebounded for a robust
              spring, seemingly inspired by the notion among investors that the
              U.S. economy was slowing and that the Federal Reserve was unlikely
              to take further action. By the end of the second quarter, this
              renewed optimism led to a market increase from the low single
              digits to a 20% total year-to-date return as of June 30, 1997.
 
                In the second half of 1997, U.S. equities saw more change. In
              August, the U.S. stock market suffered its worst month in more
              than seven years, as it reacted to the growing financial crisis in
              Asia. The turmoil peaked in late October, when the Dow dropped
              approximately 7%, one of the largest single-day drops in history.
              While most U.S. stocks have since recouped their losses, the
              economic and market uncertainty created by the Asian turmoil have
              apparently led to several shifts in investor sentiment. According
              to Federated Investors, growth stocks (stocks with higher
              price-to-earnings ratios and higher growth rates) surpassed
              expectations in the second quarter of 1997, while value stocks
              (stocks with lower prices and good potential) regained investor
              confidence during the third quarter. Phoenix Investment Counsel
              echoes this sentiment, indicating that there was a resurgence in
              the price of large-capitalization defensive stocks in late 1997.
 
              U.S. Bond Market
 
                With declining inflation, a stronger U.S. dollar, and a quickly
              evaporating U.S. budget deficit, the U.S. bond market achieved
              strong results for the fiscal year ended November 30, 1997. The
              Lehman Brothers Aggregate Bond Index, which provides a
              representative measure of the overall fixed income market, was up
              a solid 7.58%. As interest rates fell, bonds with the longest
              maturities posted the highest returns, with 30-year Treasuries up
              13%, according to Lehman Brothers. Federated Investors indicates
              that the bond market was affected by two distinct interest rate
              trends during the period. In the first six months, interest rates
              increased as the Federal Reserve took action to slow economic
              growth and prevent rising inflation. The latter half of 1997 saw a
              complete reversal, with rates falling in response to
              slower-than-expected economic activity. For the 12-month period,
              interest rates declined overall, pushing bond prices higher for
              the fiscal year.
 
                While the turmoil in Asia battered the U.S. equity market, the
              consensus among the Polaris portfolio managers was that the Asian
              crisis actually helped to strengthen sectors of the U.S. bond
              market. With increasing risks overseas, many investors turned to
              U.S. Treasuries in a "flight to quality." Federated Investors
              says, "U.S. Treasury securities became the most attractive
              investment class in the entire world as investors, at least
              temporarily, shunned the domestic and foreign stock markets, along
              with foreign bond markets." In addition, Goldman Sachs Asset
              Management points out that the Asian turmoil should reduce U.S.
              import prices, helping to tame inflationary pressures at the
              consumer level -- a trend that should also support U.S. bond
              prices.
 
                According to SunAmerica Asset Management, the positive inflation
              environment and the Asian market difficulties helped to push the
              yield on the 30-year U.S. Treasury Bond below 6.0%, its lowest
              rate in two years. While the data continues to show a rapidly

              expanding U.S. economy with an ever-tightening labor market, the
              Federal Reserve has been able to keep short-term rates steady at
              approximately 5.0%.
 
              Global Market
 
                In the international markets, the biggest news was, of course,
              the currency and stock market crises that began in Southeast Asia
              and quickly spread to other emerging markets in Latin America and
              Eastern Europe. According to Putnam Investments, the events in
              Asia left financial markets worldwide in the grip of substantial
              volatility. After the Thai government allowed the baht to float on
              July 2, the Southeast Asian currencies began crumbling, one after
              another, sending stock markets across the world reeling. In
              August, the U.S. stock market suffered its worst month in more
              than seven years, the German stock market endured a correction of
              12%, and the sell-off began in the emerging stock markets. The
              turmoil peaked in the U.S. on October 27, 1997, when the Dow
              dropped more than 7% in a single day. The Japanese economy also
              fell sharply, a reflection of its substantial business and trade
              exposure to Asia. As Asian currencies plummeted, Japan's already
              weak financial system faced rising trade deficits and loan
              defaults. By year end, the only markets in the Asian-Pacific
              region that were still positive in local currency terms were
              India, Taiwan, and Australia. Malaysia, Thailand, Indonesia, South
              Korea, and the Philippines all experienced plunges of
              approximately 70% in U.S. dollars, while Japan dropped over 25%,
              according to the Dow Jones World Stock indices.
 
              OUTLOOK FOR 1998
 
              U.S. Stock and Bond Markets
 
                Although some managers are more optimistic than others, all of
              the Polaris investment managers expect a continuation of benign
              inflation, slow economic growth, and solid corporate earnings for
              1998. SunAmerica Asset Management remains particularly bullish:
              "Nothing so far has happened to hurt the longer-term bull case for
              financial assets. In fact, the recent pullback triggered by the
              Asian crisis argues for an extension of the overall economic
              cycle, which is positive for both the U.S. stock and bond markets.
              In the near term, we believe that inflation will continue to
              remain in check (in the 2.0% range), corporate profits will stay
              positive (growth of about 5 - 6% in 1998 versus 8 - 9% in 1997),
              and liquidity will continue to push the market to new highs."
 
                Phoenix Investment Counsel is also optimistic about the U.S.
              stock market. "Looking ahead, our long-term outlook for the stock
              market remains positive. Although valuation levels have obviously
              risen for most of the market, the economy continues to grow at a
              moderate yet sustainable pace, inflation remains benign, and
              overall corporate earnings are still positive. Given these
              factors, we continue to emphasize a number of promising growth
              opportunities in the health care, energy, technology, and
              financial sectors."
 
                While still positive, Alliance Capital Management, Putnam
              Investments, and Federated Investors offer a more cautious outlook
              for U.S. equities. Alliance notes that the slowdown in Asia
              threatens an important source of profit growth for U.S.
              corporations. With valuations already near record levels, and
              signs of upward wage pressures appearing, Alliance contends that
              volatility may increase if investors become concerned about
              slowing global growth or escalating wages. "The market probably
              won't offer much more than a high single-digit return over the
              next year," concludes Alliance. Likewise, Putnam sees a rise in
              "event risk" due to the reverberations from the Far East
              situation. In addition,
 
                                                           ---------------------
                                        3
<PAGE>   5
 
- ---------------------
 
              Putnam cautions that the "aging of the strong stock market could
              result in a correction." With the potential volatility, 1998 will
              be viewed as a "stockpicker's year," says Federated -- a year when
              research-driven active management should offer greater investor
              value than market timing.
 
                In regard to U.S. bonds, the moderate growth, low inflationary
              environment should continue to support favorable returns. Both
              SunAmerica Asset Management and Goldman Sachs Asset Management
              believe that U.S. interest rates will be stable to falling over
              the near term. With the Asian turmoil and the strong U.S. dollar
              working to slow domestic economic growth, Goldman asserts, the
              Federal Reserve should refrain from raising interest rates at
              least until mid-1998.
 
                Finally, Davis Selected Advisers brings an interesting long-term
              perspective to its outlook. "Assuming a starting level of 8,000
              for the Dow and compounding that figure at 7% annually, the Dow
              would be at 64,000 in three decades. This figure is so far ahead
              of where the market is today that we tend not to worry about the
              next 2,000 points on the Dow. The compelling, long-term growth
              potential of equities is why we intend to remain committed
              stockholders in 1998, investing in shares of strong companies when
              they are out of favor in the market."
 
              Global Market
 
                Looking ahead, Putnam Investments says, "Caution is the
              watchword. We expect international stock markets to remain
              extremely volatile for the next several months. We are taking
              advantage of the widespread declines to selectively identify
              undervalued stocks. We believe prices fell indiscriminately across
              the board in many of these markets and select stocks may now
              represent attractive values."
 
                Alliance Capital Management concurs that the increase in global
              equity market volatility should continue in 1998, as uncertainty
              about prospects for corporate earnings growth rise. Balanced
              against this uncertain earnings picture, however, is a benign
              outlook for interest rates and inflation in most parts of the
              world. With the exception of Asia, the supply and demand factor
              for equities looks attractive. On another positive note, Alliance
              believes that the Asian difficulties combined with an already
              competitive pricing environment for goods and services will keep
              global inflation at bay. Central banks in the U.S. and Europe
              should remain on hold concerning changes in interest rate policy.
              Alliance adds, "We expect little change in long-term interest
              rates and little change in foreign exchange rates, the exception
              being the Japanese yen, which we expect to weaken somewhat against
              the U.S. dollar."
 
                As Morgan Stanley Asset Management looks forward, it sees a
              pickup in European growth in 1998 and a broadening of the economic
              recovery from the export-led growth to more domestic-based demand.
              In Japan, the risks persist with financial sector instability,
              weak domestic demand, and the strong impact of the Asian crisis.
              With investor confidence shaken by the events in Asia, Morgan
              Stanley believes that the most important challenge for 1998 will
              be to look beyond the uncertainties created by Asia's financial
              woes and "recapture the relatively sound fundamentals that still
              underpin the real side of the world growth equation." From a
              longer-term perspective, all of the Polaris investment managers
              still agree that international investing continues to provide
              important diversification that can help enhance returns and reduce
              risk in a portfolio consisting of mostly domestic issues.

              IN CONCLUSION
 
                Although there were several bumps along the way, 1997 turned out
              to be an impressive year for most investors. Indeed, it was the
              unprecedented third year in a row that the S&P 500 Index posted
              gains of above 20%. While these record returns have created
              windfalls for many investors, the recent market volatility and the
              divergence in performance among domestic and international
              stocks -- or even large-cap and small-cap stocks -- reminds us
              that the market can be equally unforgiving on the downside.
              Fortunately, there are many strategies to help you manage
              investment risk. Several of the most important are diversification
              and active professional management. Regardless of market
              conditions, the Polaris money managers can help you diversify your
              investments among various investment categories or asset
              classes -- a technique which reduces the negative impact that any
              one asset class can have on your overall portfolio. Our money
              managers are also committed to helping you achieve your long-term
              goals by constantly monitoring the ever-changing global markets
              and conducting the research necessary to uncover promising
              investment opportunities all around the world.
 
                As we enter 1998, we encourage you to meet with your investment
              representative to review your portfolio and to make sure your
              investment allocations in Polaris continue to meet your financial
              needs and goals. In the meantime, we thank you for choosing
              Polaris as your retirement savings investment, and we look forward
              to reporting to you again at mid-year 1998.

              including currency fluctuations, political and social instability,
              differing securities regulations and accounting standards, and
              limited public information. High-yield bonds tend to be subject to
              greater price swings than higher-rated bonds and, of course,
              payment of interest and principal is not assured. Investments in
              securities related to gold and other precious metals and minerals
              are considered speculative and are impacted by a host of worldwide
              economic, financial, and political factors. Mortgage-backed
              securities are subject to prepayment, which can result in
              reinvestment of principal at lower yields. Money market
              instruments generally offer stability and income, but an
              investment in these securities is not guaranteed by the U.S.
              government or any other entity.

SUNAMERICA SERIES TRUST
NOTES TO FINANCIAL STATEMENTS
 
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION:  SunAmerica Series Trust
(the "Trust"), organized as a Massachusetts business trust on September 11,
1992, is an open-end management investment company. It was established to
provide a funding medium for certain annuity contracts issued by Variable
Separate Account (the "Account"), a separate account of Anchor National Life
Insurance Company ("Life Company"), organized under the laws of the state of
Arizona; and by FS Variable Separate Account (the "FS Account"), a separate
account of First SunAmerica Life Insurance Company ("FS Life Company"),
organized under the laws of the state of New York.
 
  The Trust issues 21 separate series of shares (the "Portfolios"), each of
which represents a separate managed portfolio of securities with its own
investment objectives. The Trustees may establish additional series in the
future. All shares may be purchased or redeemed by the Account at net asset
value without any sales or redemption charge.
 
The investment objectives for each portfolio are as follows:
 
The Cash Management Portfolio seeks high current yield while preserving capital
by investing in a diversified selection of money market instruments.
 
The Global Bond Portfolio seeks a high total return, emphasizing current income
and, to a lesser extent, providing opportunities for capital appreciation,
through investment in high quality fixed-income securities of U.S. and foreign
issuers and through transactions in foreign currencies.
 
The Corporate Bond Portfolio seeks a high total return with only moderate price
risk by investing primarily in investment grade fixed-income securities.
 
The High-Yield Bond Portfolio seeks a high level of current income and
secondarily seeks capital appreciation by investing primarily in intermediate
and long-term corporate obligations, with emphasis on higher-yielding,
higher-risk, lower-rated or unrated securities.
 
The Worldwide High Income Portfolio seeks high current income and, secondarily,
capital appreciation, by investing primarily in a portfolio of high-yielding
fixed-income securities of issuers located throughout the world.
 
The SunAmerica Balanced Portfolio seeks to conserve principal by maintaining at
all times a balanced portfolio of stocks and bonds.
 
The Balanced/Phoenix Investment Counsel Portfolio seeks reasonable income,
long-term capital growth and conservation of capital by investing primarily in
common stocks and fixed-income securities, with an emphasis on income-producing
securities which appear to have some potential for capital enhancement.
 
The Asset Allocation Portfolio seeks high total return (including income and
capital gains) consistent with preservation of capital over the long-term
through a diversified portfolio that can include common stocks and other
securities having common stock characteristics, bonds and other intermediate and
long-term fixed-income securities and money market instruments (debt securities
maturing in one year or less) in any combination.
 
The Utility Portfolio seeks high current income and moderate capital
appreciation by investing primarily in the equity and debt securities of utility
companies.
 
The Growth-Income Portfolio seeks growth of capital and income by investing
primarily in common stocks or securities which demonstrate the potential for
appreciation and/or dividends.
 
The Federated Value Portfolio seeks growth of capital and income by investing
primarily in the securities of high quality companies.
 
The Venture Value Portfolio seeks to achieve growth of capital by investing
primarily in common stocks.
 
The Putnam Growth (formerly, the Provident Growth Portfolio), Growth/Phoenix
Investment Counsel and Alliance Growth Portfolios each seeks long-term growth of
capital by investing primarily in common stocks or securities with common stock
characteristics which demonstrate the potential for appreciation.
 
The Global Equities Portfolio seeks long-term growth of capital through
investment primarily in common stocks or securities of U.S. and foreign issuers
with common stock characteristics which demonstrate the potential for
appreciation and through transactions in foreign currencies.

The International Growth and Income Portfolio seeks growth of capital and
current income through investment primarily in common stocks and securities
principally traded on markets outside the United States that offer potential for
capital growth and current income.
 
The International Diversified Equities Portfolio seeks long-term capital
appreciation by investing in accordance with country weightings determined by
the Subadviser in common stocks of foreign issuers which, in the aggregate,
replicate broad country indices.
 
The Real Estate Portfolio seeks total return through a combination of growth and
income by investment primarily in securities of companies principally engaged in
or related to the real estate industry or which own significant real estate
assets or which primarily invest in real estate instruments.
 
The Aggressive Growth Portfolio seeks long-term growth of capital through
investment primarily in equity securities of small capitalization growth
companies.
 
The Emerging Markets Portfolio seeks long-term capital appreciation by investing
in common stocks that have above-average growth prospects primarily in emerging
markets outside the United States.
 
2. SIGNIFICANT ACCOUNTING POLICIES:  The preparation of financial statements in
accordance with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from these estimates.
In the opinion of management of the Trust, the accompanying financial statements
contain all normal and recurring adjustments necessary for the fair presentation
of the financial position of the Trust at November 30, 1997, and the results of
its operations, the changes in its net assets and its financial highlights for
the periods then ended. The following is a summary of significant accounting
policies consistently followed by the Trust in the preparation of its financial
statements.
 
  SECURITY VALUATIONS:  Stocks are stated at value based upon closing sales
prices reported on recognized securities exchanges or, for listed securities
having no sales reported and for unlisted securities, upon last-reported bid
prices. Nonconvertible bonds, debentures, other long-term debt securities, and
short-term securities with original or remaining maturities in excess of 60 days
are valued at prices obtained for the day of valuation from a bond pricing
service of a major dealer in bonds when such prices are available; however, in
circumstances where the investment adviser deems it appropriate to do so, an
over-the-counter or exchange quotation at the mean of representative bid or
asked prices may be used. Securities traded primarily on securities exchanges
outside the United States are valued at the last sale price on such exchanges on
the day of valuation, or if there is no sale on the day of valuation, at the
last reported bid price. If a security's price is available from more than one
foreign exchange, a portfolio uses the exchange that is the primary market for
the security. Developing markets securities involve risks not typically
associated with investing in securities of issuers in more developed markets.
These investments are subject to various risk factors including market, credit
and sovereign risk. The markets in which these securities trade can be volatile
and at times illiquid. Futures contracts are valued at the last sale price
established each day by the board of trade or exchange on which they are traded.
Short-term securities with 60 days or less to maturity are amortized to maturity
based on their cost to the Trust if acquired within 60 days of maturity or, if
already held by the Trust on the 60th day, are amortized to maturity based on
the value determined on the 61st day. Securities for which quotations are not
readily available are valued at fair value as determined in good faith under the
direction of the Trust's Trustees.
 
  REPURCHASE AGREEMENTS:  The Trust's custodian takes possession of the
collateral pledged for investments in repurchase agreements. The underlying
collateral is valued daily on a mark-to-market basis to assure that the value,
including accrued interest, is at least equal to the repurchase price. In the
event of default of the obligation to repurchase, the Trust has the right to
liquidate the collateral and apply the proceeds in satisfaction of the
obligation. If the seller defaults and the value of the collateral declines or
if bankruptcy proceedings are commenced with respect to the seller of the
security, realization of the collateral by the Trust may be delayed or limited.
 
  FOREIGN CURRENCY TRANSLATION:  The books and records of the Trust are
maintained in U.S. dollars. Assets and liabilities denominated in foreign
currencies and commitments under forward foreign currency contracts are
translated into U.S. dollars at the mean of the quoted bid and asked prices of
such currencies against the U.S. dollar.
 
  The Trust does not isolate that portion of the results of operations arising
as a result of changes in the foreign exchange rates from the changes in the
market prices of securities held at fiscal year-end. Similarly, the Trust does
not isolate the effect of changes in foreign exchange rates from the changes in
the market prices of portfolio securities sold during the year.
 
  Realized foreign exchange gain and losses on other assets and liabilities and
change in unrealized foreign exchange gain and losses on other assets and
liabilities include realized foreign exchange gains and losses from currency
gains or losses between the trade and settlement dates of securities
transactions, the difference between the amounts of interest, dividends and
foreign withholding taxes recorded on the Trust's books and the U.S. dollar
equivalent amounts actually received or paid and changes in the unrealized
foreign exchange gains and losses relating to the other assets and liabilities
arising as a result of changes in the exchange rate.
 
  FORWARD FOREIGN CURRENCY CONTRACTS:  Certain portfolios may enter into forward
foreign currency contracts ("forward contracts") to attempt to protect
securities and related receivables and payables against changes in future
foreign exchange
 
- ---------------------
                                       122
<PAGE>   124
 
rates or to enhance return. A forward contract is an agreement between two
parties to buy or sell currency at a set price on a future date. The market
value of the contract will fluctuate with changes in currency exchange rates.
The contract is marked-to-market daily using the forward rate and the change in
market value is recorded by the Portfolio as unrealized gain or loss. On the
settlement date, the Portfolio records either realized gains or losses when the
contract is closed equal to the difference between the value of the contract at
the time it was opened and the value at the time it was closed. Risks may arise
upon entering into these contracts from the potential inability of
counterparties to meet the terms of their contracts and from unanticipated
movements in the value of a foreign currency relative to the U.S. dollar.
Forward contracts involve elements of risk in excess of the amount reflected in
the Statement of Assets and Liabilities. The Trust bears the risk of an
unfavorable change in the foreign exchange rate underlying the forward contract.
  FUTURES CONTRACTS:  A futures contract is an agreement between two parties to
buy and sell a financial instrument at a set price on a future date. Upon
entering into such a contract the Trust is required to pledge to the broker an
amount of cash or U.S. government securities equal to the minimum "initial
margin" requirements of the exchange on which the futures contract is traded.
The contract amount reflects the extent of a Portfolio's exposure in these
financial instruments. A Portfolio's participation in the futures markets
involves certain risks, including imperfect correlation between movements in the
price of futures contracts and movements in the price of the securities hedged
or used for cover. The Trust's activities in the futures contracts are conducted
through regulated exchanges which do not result in counterparty credit risks.
Pursuant to a contract, the Portfolios agree to receive from or pay to the
broker an amount of cash equal to the daily fluctuation in value of the
contract. Such receipts or payments are known as "variation margin" and are
recorded by the Portfolios as unrealized appreciation or depreciation. When a
contract is closed, the Portfolios record a realized gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.
 
  OPTIONS:  An option is a contract conveying a right to buy or sell a financial
instrument at a specified price during a stipulated period. The premium paid by
a Portfolio for the purchase of a call or a put option is included in the
Portfolio's Statement of Assets and Liabilities as an investment and
subsequently marked to market to reflect the current market value of the option.
When a Portfolio writes a call or a put option, an amount equal to the premium
received by the Portfolio is included in the Portfolio's Statement of Assets and
Liabilities as a liability and is subsequently marked to market to reflect the
current market value of the option written. If an option which the Portfolio has
written either expires on its stipulated expiration date, or if the Portfolio
enters into a closing purchase transaction, the Portfolio realizes a gain (or
loss if the cost of a closing purchase transaction exceeds the premium received
when the option was written) without regard to any unrealized gain or loss on
the underlying security, and the liability related to such options is
extinguished. If a call option which the Portfolio has written is exercised, the
Portfolio realizes a capital gain or loss from the sale of the underlying
security and the proceeds from such sale are increased by the premium originally
received. If a put option which the Portfolio has written is exercised, the
amount of the premium originally received reduces the cost of the security which
the Portfolio purchased upon exercise of the option.
 
  CURRENCY SWAPS:  Currency swaps involve the exchange by a Portfolio with
another party of its respective rights to make or receive payments in specified
currencies. Currency swaps usually involve the delivery of the principal value
of one designated currency in exchange for the other designated currency.
Therefore, the entire principal value of a currency swap is subject to the risk
that the other party will default on its contractual delivery obligations.
Currency swaps involve elements of risk in excess of the amount reflected in the
Statement of Assets and Liabilities. Changes in the value of the swap are
reported as unrealized appreciation or depreciation in the Statement of Assets
and Liabilities. A realized gain or loss is recorded upon early termination of
such agreement.
 
  SECURITIES TRANSACTIONS, INVESTMENT INCOME, EXPENSES, DIVIDENDS AND
DISTRIBUTIONS:  As is customary in the mutual fund industry, securities
transactions are recorded on a trade date basis. Interest income is accrued
daily except when collection is not expected. Dividend income and distributions
to shareholders are recorded on the ex-dividend date except for certain
dividends from foreign securities, which are recorded as soon as the Trust is
informed after the ex-dividend date. The Trust amortizes premiums and accretes
discounts on fixed income securities, as well as those original issue discounts
for which amortization is required for federal income tax purposes; gains and
losses realized upon the sale of such securities are based on their identified
cost. Portfolios which earn foreign income and capital gains may be subject to
foreign withholding taxes at various rates.
 
  Common expenses incurred by the Trust are allocated among the Portfolios based
upon relative net assets or other appropriate allocation methods. In all other
respects, expenses are charged to each Portfolio as incurred on a specific
identification basis.
 
  The Portfolios record dividends and distributions to their shareholders on the
ex-dividend date. The amount of dividends and distributions from net investment
income and net realized capital gains are determined and presented in accordance
with federal income tax regulations, which may differ from generally accepted
accounting principles. These "book/tax" differences are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax-basis treatment; temporary differences do not require
reclassification. Dividends and distributions which exceed net investment income
and net realized capital gains for financial reporting purposes but not for tax
purposes are reported as dividends in excess of net investment income or
distributions in excess of net realized capital gains. To the extent
distributions exceed current and accumulated earnings and profits for federal
income tax purposes, they are reported as distributions of paid-in capital. Net
investment income/loss, net realized gain/loss, and net assets are not affected.

  For the year ended November 30, 1997, the reclassification arising from
book/tax differences resulted in increases (decreases) to the components of net
assets as follows:

  * Reclassification is primarily due to differing book/tax treatments for
foreign currency transactions.
 
3. JOINT REPURCHASE AGREEMENT ACCOUNT:  The Cash Management, High-Yield Bond,
SunAmerica Balanced and Aggressive Growth Portfolios, along with other
affiliated registered investment companies, transfer uninvested cash balances
into a single joint account, the daily aggregate balance of which is invested in
one or more repurchase agreements collateralized by U.S. Treasury or federal
agency obligations. As of November 30, 1997, the Cash Management, High-Yield
Bond, SunAmerica Balanced, and Aggressive Growth Portfolios had a 9.1%, 8.0%,
1.6% and 4.1%, undivided interest, respectively, which represented $13,341,000,
$11,659,000, $2,364,000 and $5,956,000, respectively, in principal amount in a
repurchase agreement in the joint account. As of such date, the repurchase
agreement in the joint account and the collateral therefore was as follows:
 
  Paine Webber Securities, Inc. Repurchase Agreement, 5.625% dated 11/28/97, in
the principal amount of $146,239,000 repurchase price $146,307,550 due 12/1/97
collateralized by $50,000,000 U.S. Treasury Note 4.75% due 10/31/98, $1,230,000
U.S. Treasury Note 6.00% due 5/01/98, $45,440,000 U.S. Treasury Note 6.125% due
3/31/98, and $50,000,000 U.S. Treasury Note 7.125% due 2/29/00; approximate
aggregate value $149,265,739.
 
4. FEDERAL INCOME TAXES:  The Trust intends to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and
distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal tax provision is
required.
 
  The amounts of aggregate unrealized gain (loss) and the cost of investment
securities for tax purposes, including short-term securities and repurchase
agreements at November 30, 1997, were as follows:

5. MANAGEMENT OF THE TRUST:  SunAmerica Asset Management Corp. ("SAAMCo" or the
"Adviser"), an indirect wholly owned subsidiary of the Life Company, serves as
investment adviser for all the portfolios of the Trust. The Trust, on behalf of
each Portfolio, entered into an Investment Advisory and Management Agreement
(the "Agreement") with SAAMCo to handle the Trust's day-to-day affairs. It is
the responsibility of the Adviser and, for certain Portfolios pursuant to
Subadvisory Agreements described below, the subadvisers, to make investment
decisions for the Portfolios and to place the purchase and sale orders for the
Portfolio transactions. Such orders may be directed to any broker including, in
the manner and to the extent permitted by applicable law, affiliates of the
Adviser or a subadviser. The Agreement provides that SAAMCo shall administer the
Trust's business affairs; furnish offices, necessary facilities and equipment;
provide clerical, bookkeeping and administrative services; and permit any of its
officers or employees to serve, without compensation, as trustees or officers of
the Trust, if duly elected to such positions. There is no subadviser for the
Cash Management, High-Yield Bond, SunAmerica Balanced and Aggressive Growth
Portfolios, and SAAMCo, therefore, performs all investment advisory services for
these Portfolios. The term "Assets", as used in the following table, means the
average daily net assets of the Portfolios.
 
  The Trust pays SAAMCo a monthly fee calculated at the following annual
percentages of each Portfolio's assets:

SUNAMERICA SERIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE TRUSTEES AND SHAREHOLDERS OF SUNAMERICA SERIES TRUST
 
In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolios, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Cash Management Portfolio, Global
Bond Portfolio, Corporate Bond Portfolio (formerly Fixed Income Portfolio),
High-Yield Bond Portfolio, Worldwide High Income Portfolio, SunAmerica Balanced
Portfolio, Balanced/Phoenix Investment Counsel Portfolio, Asset Allocation
Portfolio, Utility Portfolio, Growth-Income Portfolio, Federated Value
Portfolio, Venture Value Portfolio, Alliance Growth Portfolio, Growth/Phoenix
Investment Counsel Portfolio, Putnam Growth Portfolio (formerly Provident Growth
Portfolio), Global Equities Portfolio, International Growth and Income
Portfolio, International Diversified Equities Portfolio, Real Estate Portfolio,
Aggressive Growth Portfolio and Emerging Markets Portfolio (constituting the
twenty-one portfolios of SunAmerica Series Trust, hereafter referred to as the
"Fund") at November 30, 1997, and the results of each of their operations, the
changes in each of their net assets and the financial highlights for each of the
periods indicated, in conformity with generally accepted accounting principles.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Fund's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at
November 30, 1997 by correspondence with the custodian and brokers and the
application of alternative auditing procedures where confirmations from brokers
were not received, provide a reasonable basis for the opinion expressed above.

    COMPARISONS: PORTFOLIOS VS. INDEXES
 
              The following graphs compare the performance of a $10,000
              investment in the SunAmerica Series Trust Portfolios (with the
              exception of Cash Management) to a $10,000 investment in a
              securities index since the portfolio inception. Following each
              graph is a discussion of portfolio performance and factors
              affecting it over the last one-year period.
 
              THESE GRAPHS AND TABLES SHOW THE PERFORMANCE OF THE PORTFOLIOS AT
              THE SUNAMERICA SERIES TRUST LEVEL AND INCLUDE ALL TRUST EXPENSES
              BUT NO INSURANCE COMPANY EXPENSES ASSOCIATED WITH THE VARIABLE
              ANNUITY AND NO CONTINGENT DEFERRED SALES CHARGE. ALL DIVIDENDS ARE
              ASSUMED TO BE REINVESTED. NO EXPENSES ARE DEDUCTED FROM THE
              PERFORMANCE OF THE INDEXES.
 
              CASH MANAGEMENT
 
              SunAmerica Asset Management Corp.
 
              The Cash Management Portfolio has performed well for the year
              ended November 30, 1997. The portfolio's return was 5.22%, versus
              the Lipper Analytical composite return of 4.47%.
 
              SunAmerica Asset Management has a favorable outlook for U.S.
              interest rates. The manager expects that the financial crisis in
              Asia will slow the U.S. economy, which in combination with a
              strong U.S. dollar should keep inflation low. The focus of the
              portfolio will be finding the best relative value securities and
              structuring the portfolio to be flexible enough to meet changing
              economic conditions.
 
                     Past performance is no guarantee of future results.

GLOBAL BOND PORTFOLIO
AVERAGE ANNUAL TOTAL RETURNS AS OF 11/30/97
- -------------------------------------------------
     1-Year                             8.43%
     Since Inception (7/1/93)           7.85%
- -------------------------------------------------

(1) The J.P. Morgan Global Government Bond Index tracks the performance of bonds
    throughout the world, including issues from Europe, Australia, the Far East
    and the United States.

              The Global Bond Portfolio returned 8.43% over the one-year period
              ended November 30, 1997, versus a return of 9.25% for the J.P.
              Morgan Global Government Bond Index (hedged into U.S. dollars).
 
              One of the major factors affecting both the performance of the
              portfolio and the global bond market was the Asian financial
              crisis. While global equities were battered by Asia's financial
              woes, the recent Asian turmoil actually helped to buoy global bond
              markets. In a "flight to quality," many equity investors turned to
              bonds of developed nations that offered protection during the
              fallout. In particular, U.S. bonds benefited as the crisis in
              Southeast Asia dampened fears of higher domestic inflation over
              the near term. Federal Reserve Chairman Alan Greenspan also helped
              to ease concerns among U.S. fixed income investors, when he
              indicated that the Pacific Rim problems should have little effect
              on the overall health of the U.S. economy.
 
              In the second half of 1997, Goldman Sachs increased the
              portfolio's allocations to the U.S., German, and Italian markets,
              while decreasing its percentage of holdings in Japan and the U.K.
              During the 12-month period ended November 30, 1997, the portfolio
              benefited particularly from an overweight position in Italian
              bonds. A favorable inflation landscape and the possibility of a
              downward trend in short-term European Monetary Union interest
              rates contributed to the strength of the Italian markets. Another
              strategic move was the initiation of an overweight position in New
              Zealand in June. At the time, Goldman Sachs believed that a
              pending slowdown in the New Zealand economy would lead to lower
              long-term interest rates. However, this position has since been
              reduced given the liquidity restraints in Japan, where
              institutions are major holders of New Zealand bonds.
 
                     Past performance is no guarantee of future results.

    fixed-income indices to give a broad view of the bond market 70% reflects
    the Government/Corporate Bond Index, 29% reflects the Mortgage-Backed
    Securities Index and 1% reflects the Asset-Backed Securities Index.

              For the 12-month period ended November 30, 1997, the Corporate
              Bond Portfolio generated a return of 9.26%. In comparison, the
              Lehman Brothers Corporate Bond Index returned 7.57%, the Lehman
              Brothers Aggregate Index returned 7.58%, and the Lipper Corporate
              Debt Funds BBB Rated Index produced a return of 7.55% for the same
              period.
 
              The portfolio's positive performance was affected by two distinct
              interest rate trends during the fiscal year. The initial six
              months saw interest rates rise in response to
              stronger-than-anticipated economic activity. As business
              conditions improved, corporate securities outperformed comparable
              maturity U.S. Treasuries. The situation completely reversed in the
              second half of 1997. Economic growth slowed, interest rates fell,
              and corporate securities underperformed Treasuries. With overall
              rates declining for the period, the fiscal year was a positive one
              for high-quality, fixed-income securities.
 
              Another factor behind the portfolio's performance was the Asian
              financial difficulties. The foreign currency and stock market
              crisis which started in Southeast Asia and spread to Latin America
              created a strong "flight to quality." U.S. bonds became one of the
              most attractive investments in the world, as investors, at least
              temporarily, shunned the domestic and foreign stock markets along
              with the foreign bond markets.
 
              In terms of credit quality, the portfolio manager continued to
              maintain approximately 25% of total fund assets in high-yield,
              lower-rated corporate securities. This minority, but still
              significant, position helped generate not only an above-average
              income distribution for shareholders, but also enhanced price
              appreciation as high-yield bonds outperformed higher quality bonds
              over the past year.
 
                     Past performance is no guarantee of future results.

HIGH-YIELD BOND PORTFOLIO
AVERAGE ANNUAL TOTAL RETURNS AS OF 11/30/97
- -------------------------------------------------
     1-Year                            14.53%
     Since Inception (2/9/93)           9.95%
- -------------------------------------------------

(1)  The Merrill Lynch High-Yield Master Index includes publicly placed,
     nonconvertible, coupon-bearing U.S. domestic debt with a maturity of at
     least one year. Par amounts of all issues at the beginning and ending of
     each reporting period must be at least $10,000. Issues included in the
     index must have a rating that is less than investment grade but not in
     default.

              The High-Yield Bond Portfolio performed well for the year ended
              November 30, 1997. With an annual return of 14.53%, the portfolio
              compared favorably to the Merrill Lynch High-Yield Master Index,
              which returned 12.60% for the period.
 
              While both the portfolio and the high-yield bond market achieved
              double-digit gains during the period, they were adversely affected
              by the October 27th sell-off in global equities resulting from the
              recent turmoil in Asia. High-yield bonds issued by companies in
              cyclical industries such as paper, steel, and chemicals have been
              hit especially hard, since many of these companies have critical
              operations in Southeast Asia and other emerging markets. In
              addition, while equities have generally recaptured their losses
              from the October 27th downturn, the high-yield bond market remains
              weaker than before the sell-off.
 
              The outlook for the high-yield market depends on the resolution of
              the Asian economic difficulties. Given the uncertainties involved,
              the manager remains focused on obtaining current income within
              reasonable risk parameters. The result has been a decrease in the
              portfolio's allocation to preferred stock and zero coupon bonds.
 
                     Past performance is no guarantee of future results.

WORLDWIDE HIGH INCOME PORTFOLIO
AVERAGE ANNUAL TOTAL RETURNS AS OF 11/30/97
- -------------------------------------------------
     1-Year                              14.17%
     Since Inception (10/28/94)          18.08%
- -------------------------------------------------

(1)  The Blended Index combines 50% of the First Boston High-Yield Index and
     50% of the J.P. Morgan Emerging Markets Bond Index Plus.

(2)  The First Boston High-Yield Bond Index is a trader-priced portfolio
     constructed to mirror the public high-yield debt market. Securities in the
     index are rated B or lower.

(3)  The J.P. Morgan Emerging Markets Bond Index (EMBI) Plus is a
     market-weighted index composed of all Brady Bonds outstanding; it includes
     Argentina, Brazil, Mexico, Nigeria, the Philippines, and Venezuela.  
                           

              For the year ended November 30, 1997, the Worldwide High Income
              Portfolio returned 14.17%, compared with the 13.79% return of the
              First Boston High-Yield Index, the 13.69% return of the J.P.
              Morgan Emerging Markets Bond Index Plus, and the 13.65% return of
              the Blended Index.
 
              The portfolio's strong performance occurred in an environment of
              generally falling U.S. interest rates and a strong U.S. equity
              market. More interestingly, it occurred despite the turmoil which
              plagued many emerging markets in the latter half of 1997. While
              the U.S. economy experienced moderate growth and low inflation,
              the economic picture in the rest of the world was not as strong.
              Economic turmoil in virtually the entire Asian region, which
              gradually led to a lack of investor confidence in other emerging
              countries such as Brazil and Russia, caused both the debt and
              equity markets in those countries to tumble.
 
              The portfolio, which had a higher weighting in emerging debt
              relative to high-yield bonds, outperformed its benchmark Blended
              Index despite the sell-off in emerging markets that occurred in
              late 1997. The portfolio had no exposure to bonds in the Asian
              region throughout most of the turmoil and, as always, remained
              highly diversified, which prevented large exposures to any one
              country or market.
 
                     Past performance is no guarantee of future results.

(1) The Blended Index consists of 55% S&P 500 Index, 35% Lehman Brothers
    Aggregate Index, and 10% Treasury Bills.  Treasury Bills are short-term
    securities with maturities of one-year or less issued by the U.S.
    Government.

(2) The S&P 500 Index tracks the performance of 500 stocks representing a
    sampling of the largest foreign and domestic stocks traded publicly in the
    United States.  Because it is market-weighted, the index will reflect
    changes in larger companies more heavily than those in smaller companies.

    fixed-income indices to give a broad view of the bond market 70% reflects
    the Government/Corporate Bond Index, 29% reflects the Mortgage-Backed
    Securities Index and 1% reflects the Asset-Backed Securities Index.

              The SunAmerica Balanced Portfolio had an excellent year. For the
              12 months ended November 30, 1997, the portfolio had a return of
              21.48%. In comparison, the S&P 500 Index, the Lehman Brothers
              Aggregate Index, and the Blended Index returned 28.59%, 7.58%, and
              18.69%, respectively, for the same period.
 
              The portfolio's performance during the past 12 months was aided by
              significant positions in both the financial and health care
              sectors. The portfolio's largest equity holdings as of November
              30, 1997, were AT&T Corp., IDEC Pharmaceuticals Corp., Lucent
              Technologies, Inc., Wells Fargo & Co., and Summit Bancorp.
 
              Looking forward, the portfolio manager continues to focus on
              sectors that are expected to produce favorable earnings in any
              economic environment. Research will concentrate on companies with
              solid fundamentals and significant cash flow growth. The manager
              continues to overweight the financial and pharmaceutical sectors,
              holding companies such as Pfizer, Inc. and Eli Lilly based on
              consistent growth potential and new product launches. Effective
              asset allocation also remains critical. In 1998, the manager
              expects to increase its fixed income position to take advantage of
              the bond market's currently attractive potential.

AVERAGE ANNUAL TOTAL RETURNS AS OF 11/30/97
- -----------------------------------------------
   1-year                             13.52%
   Since Inception (10/28/94)         16.86%
- -----------------------------------------------

(1) The Blended Index consists of 35% Lehman Brothers Aggregate Index, 55% S&P
    500 Index, and 10% Treasury Bills. Treasury Bills are short-term securities
    with maturities of one-year or less issued by the U.S. Government.

(2) The Lehman Brothers Aggregate Index combines several Lehman Brothers
    fixed-income indices to give a broad view of the bond market 70% reflects

    Securities Index and 1% reflects the Asset-Backed Securities Index.

(3) The S&P 500 Index tracks the performance of 500 stocks representing a
    sampling of the largest foreign and domestic stocks traded publicly in the
    United States. Because it is market-weighted, the index will reflect
    changes in larger companies more heavily than those in smaller companies.

              The Balanced/Phoenix Investment Counsel Portfolio posted
              double-digit gains over the latest fiscal period, but lagged the
              benchmark Blended Index which consists of 55% S&P 500 Index, 35%
              Lehman Brothers Aggregate Bond Index, and 10% 90-day T-bills. For
              the 12 months ended November 30, 1997, the portfolio earned
              13.52%, versus the benchmark return of 18.69%.
 
              Positive performance factors included solid stock selection and
              modest, overweight positions in the energy and financial sectors.
              Areas which held back the portfolio's performance included
              weaker-than-expected results for technology and heath care stocks.
 
              With interest rates trending downward since mid-1997, Phoenix's
              decision to increase the size and duration of the portfolio's bond
              holdings boosted returns. Toward the end of the year, however,

- -------------------------------------------------

(1) The Blended Index consists of 40% Lehman Brothers Aggregate Index and 60%
    S&P 500 Index.

(2) The Lehman Brothers Aggregate Index combines several Lehman Brothers
    fixed-income indices to give a broad view of the bond market 70% reflects
    the Government/Corporate Bond Index, 29% reflects the Mortgage-Backed
    Securities Index and 1% reflects the Asset-Backed Securities Index.

(3) The S&P 500 Index tracks the performance of 500 stocks representing a
    sampling of the largest foreign and domestic stocks traded publicly in the
    United States. Because it is market-weighted, the index will reflect changes
    in larger companies more heavily than those in smaller companies.


              The Asset Allocation Portfolio returned 21.97% over the one-year
              period ended November 30, 1997, outperforming its benchmark (a
              blended index consisting of 60% S&P 500 Index and 40% Lehman
              Brothers Aggregate Index) at 19.98%.
 
              Among its equity holdings, the portfolio has the largest
              weightings in the financial, consumer durable, capital goods, and
              technology sectors. Since mid-1997, the biggest move has been an
              increase of approximately 5% in the weighting of the financial
              sector, which now makes up 21.2% of the portfolio's equity portion
              as of November 30, 1997. In terms of fixed income, the portfolio's
              largest allocation is in the mortgage-backed sector (33.0%),
              followed closely by corporate bonds (27.4%).
 
              Since the market sell-off on October 27, 1997, concerns regarding
              the impact of the Asian crisis on U.S. corporate earnings have
              grown. Goldman Sachs' strategy of investing in those issues whose
              valuations are low when compared to an industry group or the
              market as a whole has helped to lessen the negative impact of the
              Asian crisis on the portfolio. Given the global fallout, however,
              it appears that U.S. corporate profit growth is poised for a
              slowdown in 1998. In this environment, the manager will continue
              to seek fundamentally sound organizations whose strong balance
              sheets, market presence and management philosophies should
              continue to make them attractive investments over the near and
              intermediate term.

- -----------------------------------------------
   1-year                             21.26%
   Since Inception (10/28/94)         19.39%

(1) The S&P 500 Index tracks the performance of 500 stocks representing a
    sampling of the largest foreign and domestic stocks traded publicly in the
    United States. Because it is market-weighted, the index will reflect
    changes in larger companies more heavily than those in smaller companies.

(2) The Blended Index is comprised of 35% S&P Utility Index and 65% for the S&P
    Communications Service Index, on a market capitalization weighted basis.
    The S&P Utility Index is presently comprised of 40 stocks from the electric
    and natural gas industries. The S&P Communications Service Index is
    comprised of the companies listed in the telecommunications sectors of the
    S&P 400, 500, and 600. Created in July of 1996, the S&P Communications
    Service Index includes cellular and wireless service providers including
    pagers, long distance providers and the telephone group companies (local
    service providers).

 
              The Utility Portfolio posted a double-digit return of 21.26% for
              the year ended November 30, 1997 -- strong results considering the
              environment for utilities at the beginning of 1997. In comparison,
              the S&P 500 Index returned 28.59% for the period, while the
              Blended Index returned 33.12%.
 
              As 1997 began, utilities had trailed the overall stock market for
              years. A booming stock market and uncertainty about the industry's
              future after deregulation created a poor environment for the
              group. Performance in the first quarter of the fiscal year
              reflected this uncertainty, as the S&P 500 Index rose 5% while the
              S&P Utility Index (consisting of electric and gas stocks) returned
              0.67%. However, as the turmoil in Asia unfolded and U.S. stocks
              hit record high valuations, the appeal of traditional utilities
              has grown. The transition of the electric industry from monopoly
              to competition has also progressed better than expected. Mergers
              and acquisitions have supported all three utility sectors as
              companies reduce costs and plan competitive strategies. In the
              last two months alone, the S&P Utility Index and Communications
              Index rose 8.1% and 16.0%, respectively, while the S&P 500 Index
              returned 1.1%.
 
              Federated remains optimistic about the prospects for the Utility
              Portfolio in the year ahead. Valuations are especially appealing
              for electric and gas stocks, and fundamentals are improving. This
              is the opposite of conditions for the overall stock market, where
              valuations remain near all-time highs and earnings risks seem to
              be rising. The turmoil in Asia adds to the appeal of utilities, a
              primarily domestic industry that is undergoing profound change
              that will create opportunities. The portfolio is entering 1998
              with substantially reduced overseas exposure and larger holdings
              of domestic electric utilities and gas companies.
 
                     Past performance is no guarantee of future results.

United States. Because it is market-weighted, the index will reflect changes in
larger companies more heavily than those in smaller companies.

              In the 12 months ended November 30, 1997, the Growth-Income
              Portfolio returned 30.11%, compared to 28.59% for the S&P 500
              Index.
 
              The portfolio's strong performance resulted from favorable stock
              selection in a variety of industries. Stocks in the technology and
              financial sectors, including Dell, Compaq, MBNA and Merrill Lynch,
              made particularly important contributions to overall returns.
 
              In the last year, the U.S. equity market has benefited from a
              combination of strong economic growth and modest inflation. In
              recent months, however, the economic trends have begun to look a
              little less favorable. The slowdown in Asia threatens an important
              source of profit growth for U.S. corporations. On the cost side,
              evidence of upward pressure on wages is starting to appear. The
              stock market's current valuation, however, does not appear to be
              based on any concern about deteriorating fundamentals. The S&P 500
              Index is now trading at 20 times its 1998 estimated earnings. With
              P/E ratios at historically high levels, they may begin to trend
              downward if investors become concerned about slowing global growth
              or escalating wages. In this economic environment, the market is
              likely to experience greater volatility in 1998 than in the last
              several years.

(1)  The S&P 500 Index tracks the performance of 500 Stocks representing a

     changes in larger companies more heavily than those in smaller companies.

 
              For the fiscal year ended November 30, 1997, the Federated Value
              Portfolio posted a return of 25.75%, versus 28.59% for the S&P 500
              Index.
 
              Although the U.S. stock market continued to show solid strength in
              1997, price fluctuations on a daily basis have increased as
              investors show concern about the direction of the economy and
              interest rates. The portfolio's focus on quality stocks and strict
              valuation disciplines should help to protect shareholders from
              this increased volatility. Recent emphasis has been on
              high-quality, well-run companies that, for various reasons, have
              not participated fully in the record bull market of the past
              several years. Stocks that were added during the period include
              Sun Company, Inc., a large U.S. refinery in the midst of a company
              restructuring as well as an improving industry outlook; Lexmark
              International Group, a manufacturer of PC printers that has been
              gaining market share at the expense of Japanese competitors; and
              Viacom, Inc., a dominant player in the video entertainment
              industry with unprecedented low valuations.
 
              With stock prices near all-time highs and company fundamentals
              showing signs of uncertainty, the portfolio continues to be
              underweight in the technology sector. Conversely, Federated has
              increased holdings in the energy and retailing sectors, where
              valuations are extremely attractive and global industrialization
              will continue to expand demand.
 
                     Past performance is no guarantee of future results.

              The Venture Value Portfolio has performed well this year,


              delivering a total return of 29.62% for the 12-month period ended
              November 30, 1997. This compares favorably to the 28.59% return of
              the S&P 500 Index.
 
              With a bull market that has already lasted nearly eight years
              without major corrections, it is important for investors to
              maintain realistic expectations. In Davis' point of view, the way
              to obtain a bargain at this stage in a bull market is to take
              advantage of volatility on the downside. By understanding company
              fundamentals through careful, in-depth research, the portfolio
              managers at Davis can move quickly and act with conviction when
              there is an inevitable rotation out of one industry group to
              another.
 
              In terms of sector concentration, the Venture Value Portfolio
              remains focused on financial services, technology, and energy,
              with stocks from these sectors comprising 21.57% of the
              portfolio's total holdings. Travelers, American Express, and
              General Re are among the top holdings in the financial services
              sector. IBM, the portfolio's largest holding, and Intel are two
              technology companies that are expected to generate solid returns
              over the long term. Schlumberger and Halliburton are two
              energy-related stocks that should also offer investors long-term
              growth opportunity.

(1)  The Russell 1000 Growth Index consists of stocks with a greater-than-

     price-to-book and price-earnings ratios, lower dividend yields and higher
     forecasted growth values.              
 
              The Alliance Growth Portfolio achieved returns of 27.80% for the
              12-month period ended November 30, 1997, outperforming the Russell
              1000 Growth Index at 26.52%.
 
              Performance over the 12-month period was driven both by
              overweighted positions in the technology, financial services, and
              health care (primarily drugs and pharmaceuticals) sectors and by
              very strong stock selection. Technology stocks that made positive
              contributions included Dell, Compaq, and Microsoft. MBNA, Merrill
              Lynch, Norwest Bank and Morgan Dean Witter were some of the
              notable winners in the financial services sector. In health care,
              both Schering Plough and Pfizer appreciated over 80 percent during
              the 12-month period. Several retail stocks performed well
              including Home Depot, Dayton Hudson, and Kohl Department Stores.
              Other stocks that contributed positively to performance included
              AirTouch, United Airlines, and MCI Communications. Stocks that had
              a negative performance impact included First Data Card, Sears,

(1) The S&P 500 Index tracks the performance of 500 stocks representing a
    sampling of the largest foreign and domestic stocks traded publicly in the
    United States. Because it is market-weighted, the index will reflect changes
    in larger companies more heavily than those in smaller companies.


              The Growth/Phoenix Investment Counsel Portfolio provided strong
              returns over the last 12 months, but lagged its benchmark. For the
              fiscal year ended November 30, 1997, the portfolio earned 19.78%,
              versus a return of 28.59% for the S&P 500 Index. Solid stock
              selection in the health care, energy and consumer sectors aided
              performance. Individual stocks which produced impressive gains for
              the portfolio included Pfizer, Guidant, Liberty Media,
              Halliburton, and Travelers Corp. Areas of underperformance
              included holdings in the finance and technology sectors.
 
              Looking ahead, Phoenix believes that the long-term outlook for the
              stock market remains positive. Although valuation levels have
              obviously risen for most of the market, the economy continues to
              grow at a moderate yet sustainable pace, inflation remains benign,
              and projections for corporate earnings are still favorable. The
              portfolio's stock selection continues to focus on firms that
              possess above-average earnings potential, superior management, and
              strong industry fundamentals.
 
                     Past performance is no guarantee of future results.

    forecasted growth values.

(2) The S&P 500 Index tracks the performance of 500 stocks representing a

              For the 12 months ended November 30, 1997, the Putnam Growth
              Portfolio returned 26.01%, while the Russell 1000 Growth Index
              returned 26.52% and the S&P 500 Index returned 28.59%. The
              portfolio was previously named the Provident Growth Portfolio and
              was managed by Provident Investment Counsel. On April 16, 1997,
              Putnam Investments assumed responsibility for managing the
              portfolio in conjunction with a name change to the Putnam Growth
              Portfolio. After this reporting period, the portfolio will no
              longer be measured against the Russell 1000 Growth Index. The new
              manager believes that a more accurate reflection of the holdings
              in the portfolio would be the
              S&P 500 Index.
 
              The portfolio's performance was aided by strategic positioning.
              Putnam expanded the capitalization range of portfolio holdings
              (within the defined limits of its discipline), focusing on
              domestic firms. The portfolio's emphasis on the finance,
              technology, and health care sectors contributed to the
              double-digit performance, as did the underweighting of consumer
              staples and basic industries.
 
              With the ongoing uncertainties regarding Southeast Asia, the
              portfolio continues to focus on stocks whose earnings are largely
              domestic. Putnam continues to overweight the technology, finance,
              and health care sectors. The manager also finds consumer
              cyclicals, particularly value-oriented retailers, to be
              attractive; however, it is cautious about the 1998 earnings
              outlook. The consensus expectations of only a few weeks ago have
              declined sharply, given a reassessment of the reverberations from
              the Far East situation. The probability of event risk has risen,
              and the aging of the strong stock market could result in a
              correction. Offsetting these concerns are the continued low levels
              of interest rates and inflation, the attractiveness of U.S.
              equities as a safe haven, and the continued shrinkage of stock
              availability (due to industry consolidations) while demand remains
              high. In this environment, Putnam is maintaining its disciplined
              approach to stock selection, an attribute which should help
              produce competitive, superior returns over time.
 
                     Past performance is no guarantee of future results.

              13.01%.
 
              For the period, the generally underweight position in Japan and
              overweight position in Europe assisted performance. Exposure to
              Southeast Asia during the period was primarily under benchmark
              levels. The negative impact of slightly underweighting U.S.
              equities relative to the benchmark was more than offset by strong
              stock selection. Assisting performance for the 12 months were
              positions in financials (North America and Europe) and technology
              (U.S. and Japan) issues. However, in the fourth quarter of the
              fiscal year, the latter group detracted from returns as concerns
              about growth and valuations resulted in a correction in share
              prices.

(1) The Morgan Stanley Capital International Europe, Australia, and Far East
    (EAFE) Index represents the foreign stocks of 19 countries in Europe,
    Australia and the Far East.

 
              With an inception date of June 2, 1997, the International Growth
              and Income Portfolio increased 4.10% from inception through
              November 30, 1997, outperforming the Morgan Stanley Capital
              International Europe, Australia and Far East (EAFE) Index, which
              fell 4.14% during the period in U.S. dollar terms.
 
              International stocks enjoyed strong returns during much of the
              six-month period since the portfolio's inception, despite sharp
              declines, especially late in the year in Southeast Asia.
              Fortunately, the portfolio did not hold any stocks in the five
              Asian countries that suffered the heaviest losses: Thailand,
              Malaysia, the Philippines, Indonesia, and South Korea. The
              Japanese market also fell sharply; however, the portfolio's market
              weight in Japan was far below the EAFE index.
 
              The portfolio outperformed the EAFE index primarily because of
              stock selection. Putnam's bottom-up investment strategy focuses on
              identifying large-cap stocks of companies outside the U.S. that
              are experiencing positive fundamental changes and also appear
              undervalued. Akzo-Nobel, a Dutch chemical/pharmaceutical that is
              benefiting from recent cost reductions in its fiber business and
              the positive reception of new products from its pharmaceuticals
              company, was among the strongest performers during the six-month
              period, up 38%. The portfolio also was boosted by Scottish Power,
              a U.K. utility that implemented internal cost reductions and
              consolidations during the period while experiencing a
              less-than-expected windfall tax charge. The stock gained 32% in
              the period. National Westminster Bank also enjoyed a sizable rise
              in value, increasing 23%. Under the guidance of a new chief
              financial officer, the bank initiated a major cost reduction
              program this year featuring significant branch consolidation and
              workforce reductions. Other strong performers included ENI, an
              Italian oil company, up 17%, and Nestle, which advanced 15%.

(1) The Morgan Stanley Capital International Europe, Australia, and Far East
    (EAFE) Index represents the foreign stocks of 19 countries in Europe,
    Australia and the Far East.
 
              For the year ended November 30, 1997, the International
              Diversified Equities Portfolio generated a return of 3.52%, as
              compared to the 7.07% return of the Morgan Stanley Capital
              International Europe, Australia and Far East (EAFE) Index, its
              benchmark. Overall portfolio returns were affected by a large
              dichotomy in performance among the major economies in the world.
              While the economies in the U.S. and continental Europe were either
              strong or improving, the Asian markets fell dramatically. The
              Japanese economy collapsed in mid-1997 after a sales tax increase
              dented consumer demand. This was compounded by the turmoil in
              Southeast Asia, as one Asian currency after another dropped in
              value.
 
              In response, Morgan Stanley Asset Management (MSAM) increased the
              portfolio's allocation to Europe mainly by moving to an overweight
              position in the U.K., now the portfolio's largest holding. With
              robust economic growth and strong exports, U.K. equities are
              attractively valued, particularly relative to bonds. Net trade
              should continue to be a driver of growth as the recovery in
              Continental Europe strengthens and demand for U.K. goods
              increases.
 
              The portfolio remains underweight in Asia, as many Asian
              governments continue to be reluctant to implement the tough
              economic and regulatory policies necessary to restore investor
              confidence and market stability. Investors appear concerned about
              reinvesting in the region until there is more certainty about
              government allocation of resources and a better sense of the
              credit quality implications of the currency and stock market
              crashes. MSAM has also decreased the allocation to Japan, a
              country hit hard by the overall slowdown in Asia. Approximately
              40% of Japanese exports are distributed in Asia, and the
              competitive devaluation of the Asian currencies have made Japanese
              goods less competitive.

(1)  The Morgan Stanley Real Estate Investment Trust (REIT) Index is a
     capitalization-weighted index with dividends reinvested of mostly actively
     traded real estate investment trusts and is designed to be a measure of
     real estate equity performance. The index was developed with a base value
     of 200 as of December 31, 1994.

              The Real Estate Portfolio was launched on June 2, 1997. The
              portfolio performed well during the period, delivering a total
              return of 15.30% from inception on June 2, 1997 through November
              30, 1997. Its benchmark, the Morgan Stanley Real Estate Investment
              Trust Index, achieved a return of 16.08% for the same period.
 
              The portfolio continues to emphasize three real estate sectors,
              which make up over 50% of its assets: full-service hotels,
              apartment buildings in California, and the office arena. Key
              holdings include Patriot American Hospitality, Crescent Real
              Estate Equities, Cali Realty and Vornado Realty Trust. The
              portfolio remains well diversified, with its largest holding
              Crescent Real Estate at 3.28% of total assets.
 
              Unlike stocks and bonds, real estate is the one asset class that
              Davis believes is still undervalued. Even after the strong
              recovery in real estate this year, most types of properties remain
              closer to their bottom prices than their historic highs.
              Currently, only about $150 billion worth of real estate is traded
              publicly, often in the form of REITs. Over the next four or five
              years, that amount should increase substantially, as more and more
              investors discover the enormous long-term growth potential that is
              undervalued in today's marketplace.
 
                     Past performance is no guarantee of future results.

     total market capitalization.  The Index was developed with a base ????????
     as of December 31, 1986.

              For the year ended November 30, 1997, the Aggressive Growth
              Portfolio returned 13.62%, following a very challenging month of
              October for growth stocks. The portfolio's performance trailed the
              23.16% return of its benchmark Russell 2000 Index. Factors that
              had an impact on the negative performance included the October
              sell-off in growth stocks and the currency crisis in Asia.
 
              As of September 30, 1997, the portfolio had returned over 20% for
              the year. The portfolio had been positioned for a continuation of
              modest economic growth and flat to lower interest rates, with over
              30% of assets in the technology sector and the rest diversified
              among growth issues in numerous sectors. However, the growth stock
              universe was severely impacted in the month of October by the dual
              concerns of September earnings reports and the new Asian currency
              crisis, which affected all growth issues, but most particularly
              technology stocks.
 
              Perceiving that growth would moderate and that the value of
              defensive sectors would rise, the manager repositioned the
              portfolio to increase its exposure to consumer staples (4.7%),
              consumer discretionary (6.3%), and financials (nearly 20%), while
              decreasing its growth technology position (18.5%). The portfolio
              remains overweighted in energy (16%), consisting of small oil and
              gas service stocks, as the manager believes that increased
              drilling activity will continue worldwide.
 
                     Past performance is no guarantee of future results.

EMERGING MARKETS PORTFOLIO
Total Return as of 11/30/97*

(1) The Morgan Stanley Capital International (MSCI) Emerging Markets--Free Index
     is a capitalization-weighted equity index composed of companies that are
     representative of the market structure of the following countries:
     Argentina, Brazil, Chile, China, Columbia, Czech Republic, Greece, Hungary,
     India, Indonesia, Israel, Jordan, Korea, Malaysia, Mexico, Pakistan, Peru,
     Philippines, Poland, Portugal, South Africa, Sri Lanka, Taiwan, Thailand,
     Turkey, and Venezuela.

              The Emerging Markets Portfolio became available in the Trust on
              June 2, 1997. From inception on June 2, 1997 through November 30,
              1997, the portfolio returned -19.70%, versus the Morgan Stanley
              Capital International Emerging Markets Free Index, which posted a
              return of -22.75%. The major factor behind the negative
              performance of both the portfolio and the emerging markets sector
              was the financial crisis in Asia.
 
              During the period, Putnam continued to focus on longer-term
              strategic investing, seeking potential capital appreciation in
              emerging markets through both country and stock selection. In
              terms of regional concentration, the portfolio emphasized Latin
              America at the expense of the troubled Asian markets. Within Latin
              America, the focus shifted from Brazil in favor of Argentina and
              Mexico, where growth opportunities and economic fundamentals were
              more attractive. Elsewhere, the relatively small allocation to
              Russia contributed positively to performance, despite the
              volatility in that market. Stock selection also supported the
              portfolio. While any Asian exposure, such as technology stocks in
              Taiwan, cost the portfolio potential returns, the portfolio was
              successful in avoiding the Asian banking sector, where share
              prices fell sharply. In contrast, the portfolio's consumer
              holdings in Mexico performed well.
 
              Putnam expects a significant level of volatility in the emerging
              markets through the first half of 1998 as Asian currencies find an
              equilibrium level. Interest rates will likely remain volatile in
              the region, and markets are currently very illiquid. This means
              there could be sharp upward moves as well. Throughout this period
              of uncertainty, Putnam will continue to populate the portfolio
              with companies that have exceptionally strong balance sheets,
              proven export competitiveness, and management that is both tried
              and tested. In addition, cash has been maintained at the 5% - 6%
              level to help provide protection against potential volatility in
              the global capital markets.
 
                     Past performance is no guarantee of future results.
