              DEAR INVESTOR:
 
                We are pleased to present our semiannual report for the
              SunAmerica Series Trust, one of the underlying trusts for the
              Polaris Variable Annuity from Anchor National Life Insurance
              Company and First SunAmerica Life Insurance Company, and for the
              Polaris(II) Variable Annuity from Anchor National Life Insurance
              Company.
 
                You may already be aware that the SunAmerica Series Trust has
              welcomed some exciting new investment opportunities into its ranks
              of investment options. Besides the existing Venture Value
              Portfolio, Davis Selected Advisers, L.P. manages the new Real
              Estate Portfolio, which became available June 2, 1997. You may
              already be familiar with the name Putnam Investments, which
              assumed management of the Putnam Growth Portfolio (formerly named
              the Provident Growth Portfolio) April 16, 1997. Putnam also
              manages the new International Growth and Income and Emerging
              Markets Portfolios in the SunAmerica Series Trust, which became
              available June 2, 1997. As these portfolios are new to the Trust
              and have not yet accumulated performance history, you can look
              forward to receiving more information on them in your 1997
              SunAmerica Series Trust annual report at the end of January 1998.
 
                The following is a combined perspective on the U.S. and global
              economies over the past six-month reporting period from eight of
              the money managers that manage portfolios in the Polaris and
              Polaris(II) variable annuities (excluding Wellington Management
              Company LLP, which manages the portfolios in the Anchor Series
              Trust, for which you will receive a complete report in about one
              month).
 
              ECONOMIC OVERVIEW -- UNITED STATES
 
                The economic environment over the past six months has been one
              of strong market returns, low unemployment and low inflation,
              reports Davis Selected Advisers, L.P. ("Davis") and Phoenix
              Investment Counsel ("Phoenix"). Federated Investors ("Federated")
              adds that the soaring stock market is making Americans feel
              wealthy, further encouraging spending. Such momentum raises some
              concerns, warns Federated, noting that an extensive period of
              above-normal growth in an economy operating near its potential is
              a recipe for inflation. Therefore, Federated believes the U.S.
              Federal Reserve Board's early spring move to raise short-term
              interest rates may be followed by additional rate hikes later in
              the year, as it attempts to prevent inflation from building over
              the next year or two.
 
              BOND MARKET
 
                According to Federated, the high-quality bond market experienced
              a negative turn in the early part of this year due in large part
              to stronger-than-expected economic activity in late 1996 and early
              1997, eventually culminating in the Federal Reserve raising
              interest rates in February. However, April brought a strong bond
              market rally as inflation remained very low. Obviously, additional
              rate hikes later this year would adversely impact the bond market.

- ---------------------
 
              STOCK MARKET
 
                According to Federated, the U.S. stock market has shown
              surprising strength in the first five months of the year,
              especially given the strength of 1995 and 1996. Consumer spending
              is strong as a tight labor market fosters rising wages, increased
              job security, and higher consumer confidence. The resulting
              increased consumption has fueled accelerated production, and an
              underlying growth in capital spending. Only a rising dollar casts
              a shadow on this positive economic backdrop. However, currency
              movements affect trade flows with a lag, so Federated believes
              that any dampening effect of a rising dollar should not be a
              concern until later this year.
 
                Phoenix also notes the continuing strength in the equity
              markets, believing it is driven predominantly by the very large
              market capitalization companies that dominate the S&P 500 Index.
              The emphasis on these stocks has been fueled by a more pronounced
              move into index funds, says Phoenix, as well as investors' quest
              for perceived safety afforded by higher quality companies during a
              period of mounting uncertainty. Phoenix believes the stock market
              will continue to make progress, but at more moderate rates of
              return than in the past two years.
 
              WHERE IS THE U.S. ECONOMY HEADED?
 
                SunAmerica Asset Management Corp. ("SAAMCO") believes that the
              first quarter of 1997 will prove to be the strongest of the year,
              and that GDP growth will continue to slow to a more sustainable
              2.5% - 3.0% for the remainder of the year. Some factors triggering
              this are a higher savings and investment rate and a slower
              spending rate by consumers, and some evidence of saturation in key
              consumer buying areas such as retail apparel and personal
              computers.
 
                Going beyond 1997, Davis expects the Dow to approach 10,000
              around the turn of the century, punctuated by volatility and
              corrections of up to 1,000 points along the way. Even so, the Dow
              has increased from 1,000 to 7,000 very rapidly, and Davis cautions
              that percentage gains may not be as spectacular as they have been
              in the past recent years.
 
              ECONOMIC OVERVIEW -- GLOBAL MARKETS
 
                In the face of a painful yet inevitable move toward Europe's
              implementation of the European Monetary Unit (EMU), Alliance
              Capital Management, L.P. ("Alliance") believes the current
              environment remains very supportive of global economic growth.
              Policy constraints have kept European short-term interest rates at
              record lows, while Japanese rates, if eventually raised, would
              lift from emergency lows of .5% to normal cyclical lows. In fact,
              the weakening Japanese yen has offered support to Japanese
              economic activity, and has started to make a contribution to
              corporate profits. Capital spending in Japan is on a solid
              upswing.
 
                Goldman Sachs Asset Management ("GSAM") finds that the
              restlessness surrounding the EMU and its direction have helped to
              keep bond prices under pressure in continental Europe as investors
              question Germany's leadership role in the EMU process. This,
              coupled with the Socialist victory in France, has raised questions
              about the future of EMU and of interest rates in general.

              WHERE ARE THE GLOBAL MARKETS HEADED?
 
                Morgan Stanley Asset Management Inc. ("MSAM") forecasts moderate
              world economic growth for the remainder of 1997, with little
              inflationary pressure. The manager expects the U.S. economy to
              slow from its scorching pace of the last six months, while growth
              in both Japan and Europe should post at approximately 2.5% for
              this calendar year. Non-U.S. growth is supported by continued
              monetary accommodation and currency devaluation in the yen and
              deutsche mark blocs. These positive growth forces are only partly
              offset by the global trend toward fiscal restraint. Recent signs
              of an economic pickup in Hong Kong, Singapore and Australia fit
              into MSAM's thesis of a cyclical recovery in Asia.
 
                The following is an analysis of each portfolio in the SunAmerica
              Series Trust, as reported by its respective money manager. The
              reporting period is from November 30, 1996 to May 31, 1997.
 
              CASH MANAGEMENT -- SUNAMERICA ASSET MANAGEMENT CORP.
 
                This portfolio performed quite well over the six-month reporting
              period, returning 2.48%. This positive performance can be
              attributed to the portfolio's slightly longer average days to
              maturity (about 60 days) as compared to the Donaghue average of
              about 55 days at the end of May. Because the Federal Reserve will
              most likely remain on hold for at least the next few months,
              SAAMCO expects to begin reducing the average maturity closer to
              the current Donaghue average of about 52 days. SAAMCO will
              continue to search for securities with the best relative value
              characteristics and will structure the portfolio to provide
              flexibility in a very dynamic market.
 
              CORPORATE BOND -- FEDERATED INVESTORS
 
                This portfolio returned 1.49% for the six-month reporting
              period. The high-quality bond market experienced a negative turn
              in the early part of 1997 due in large part to stronger than
              expected economic activity late in 1996 and early in 1997,
              eventually culminating in the Federal Reserve raising interest
              rates in February of this year. However, April saw a strong rally
              in the bond market as inflation remained very low. With the recent
              economic strength and volatility in the bond market, Federated
              believes it is likely that the portfolio's high yield allocation
              will be maintained to enable a larger income flow with reduced
              sensitivity to interest rates.
 
              GLOBAL BOND -- GOLDMAN SACHS ASSET MANAGEMENT
 
                For the six-month period ended May 31, 1997, the Global Bond
              Portfolio returned 1.55%. According to Goldman Sachs, the
              socio-politically driven weakness in the European market was
              somewhat offset by strength in the U.K. and Australia, where the
              fiscal policies of the new Labour government and an interest rate
              cut by the Royal Bank of Australia in May, respectively, have
              helped bond prices.
 
              HIGH-YIELD BOND -- SUNAMERICA ASSET MANAGEMENT CORP.
 
                For the six-month period ending May 31, 1997, this portfolio
              returned 4.45%, in reaction to a strong first three months
              followed by a weak second fiscal quarter. The weak showing
 
                                                           ---------------------
 
                                        3
<PAGE>   5
 
- ---------------------
 
              in the latter quarter can be attributed to the portfolio's
              overweighted position in telecommunications, as that sector was
              hit particularly hard during the market selloff in March and
              April. Most of the telecommunications holdings began to rally in
              May, and the manager remains constructive about the sector.
              Besides telecommunications, the portfolio is currently
              overweighted in the manufacturing and financial services sectors,
              and is underweighted in gaming, retail and restaurants. All other
              sectors are close to market weightings.
 
              WORLDWIDE HIGH INCOME -- MORGAN STANLEY ASSET MANAGEMENT INC.
 
                During the six months ended May 31, 1997, the portfolio returned
              9.42%. According to MSAM, improving fundamentals in many emerging
              countries and a series of upgrades by the major rating agencies
              helped to immunize developing country debt from the negative U.S.
              environment and contribute to the portfolio's return. The
              portfolio's performance can be attributed to increased allocations
              to the debt of eastern European economies, as well as the debt of
              some African countries. MSAM continues to maintain a highly
              diversified portfolio, with the largest foreign concentrations in
              Argentina, Brazil and Mexico.
 
              SUNAMERICA BALANCED -- SUNAMERICA ASSET MANAGEMENT CORP.
 
                The SunAmerica Balanced Portfolio posted a 7.85% return for the
              six months ended May 31, 1997. SAAMCO feels that the current
              period of U.S. domestic prosperity should last for at least
              several more years, and expects that the U.S. stock markets will
              continue to move higher to reflect this positive economic
              backdrop; both fixed income and equity products are expected to
              continue to provide very competitive returns.
 
                To fully participate in this economic renaissance, SAAMCO
              strives to position the portfolio in those sectors and in those
              companies which have the best global outlook and are leaders in
              their particular product areas. The portfolio is currently
              structured 67% in equities and 33% in cash and fixed income, with
              the equity portion concentrated in financial and
              interest-sensitive stocks, health care and technology. The
              portfolio's largest equity holdings include Motorola, Delta
              Airlines, Alluminum Co. of America, IBM, Dell Computers, Warner
              Lambert and Chase Manhattan Corp.
 
              BALANCED/PHOENIX INVESTMENT COUNSEL
 
                For the six-month period ended May 31, 1997, the
              Balanced/Phoenix Investment Counsel Portfolio posted a 4.29%
              return. For the period, sector selection within the fixed income
              market was key for the fixed income portion of the portfolio. The
              portfolio benefited further from strong stock selection in the
              financial services and consumer staples sectors, as well as
              Phoenix's decision to increase the portfolio's equity exposure
              after the stock market correction in mid-April. Allocations to
              emerging markets and mortgage-backed securities also delivered
              strong relative performance.
 
              ASSET ALLOCATION -- GOLDMAN SACHS ASSET MANAGEMENT
 
                For the six-month period ended May 31, 1997, the Asset
              Allocation Portfolio returned 11.51%. The portfolio's holdings
              were split 61% in equities, 37% in fixed income and 2% in cash for
              the reporting period.

<PAGE>   6
 
- ---------------------
 
                As the strength in first-quarter 1997 GDP growth indicates,
              corporate earnings continued to remain strong, fueled by
              heightened consumer spending. Within the equity portion of the
              portfolio, the consumer durables, financial, and transportation
              sectors performed well, bearing out the expectation that continued
              benign inflation will restrain the Federal Reserve from tightening
              monetary policy in the near future. Top equity holdings included
              SunBeam, Lear, Unicom, Cigna and Avnet.
 
                In the fixed income portion of the portfolio, the increase in
              holdings of U.S. Treasuries has offset decreases in the
              pass-through and corporate sectors, in which GSAM holds cautious
              and neutral views, respectively.
 
              UTILITY -- FEDERATED INVESTORS
 
                This portfolio's performance of 7.36% for the six-month
              reporting period was bolstered in particular by its international
              holdings as well as its telephone stocks and certain natural gas
              stocks. Looking ahead, Federated expects to see more merger
              activity positively affecting the natural gas sector, while
              electric stocks should benefit from the lifting of regulatory
              uncertainty.
 
                The telecommunications sector remains the clear winner among the
              portfolio's subsectors thus far this year, as many phone companies
              continue to exhibit double-digit earnings growth. As investors
              become increasingly uncomfortable about the sustainability of
              overall stock market gains, the manager expects this portfolio
              will be used for its defensive qualities.
 
              GROWTH-INCOME -- ALLIANCE CAPITAL MANAGEMENT L.P.
 
                This portfolio posted a 14.36% return for the six-month period
              ending May 31, 1997. The portfolio benefited from both
              overweighted positions and strong issue selection within the
              technology, consumer non-durables, and financial sectors. Leading
              contributors to performance within technology included Microsoft,
              Dell, Intel, Applied Materials, and Compaq. Outperformers in the
              consumer non-durables sector included Philip Morris, Coca Cola,
              Procter & Gamble and Colgate Palmolive. The financial industry
              sector was led by holdings in Merrill Lynch, American Express and
              MBNA. Also aiding the portfolio's performance were underweighted
              positions in the consumer durables, raw materials and utility
              sectors.
 
              FEDERATED VALUE -- FEDERATED INVESTORS
 
                For the six months ended May 31, 1997, the Federated Value
              Portfolio returned 11.63%. Federated attributes the portfolio's
              overall strong performance to being fully invested, as well as to
              an orientation toward quality selections, which often occurs when
              the direction of the stock market is in question. For the
              remainder of the year, the manager's investment position will be
              one of stock selection vs. market participation.
 
              VENTURE VALUE -- DAVIS SELECTED ADVISERS, L.P.
 
                For the six-month period ended May 31, 1997, the portfolio
              posted a 12.47% return. Davis indicates that financial brand names
              are emerging as Baby Boomers enter their peak earning, saving and
              investing years. To capitalize on this, Davis has purchased large
              holdings in Wells Fargo and Travelers, both of which were
              purchased at less than 10 times
 
                                                           ---------------------
 
                                        5

- ---------------------
 
              earnings -- well in keeping with Davis' profile of overlooked,
              undervalued growth companies selling at value prices. American
              Express, which Davis believes is one of the great brands
              worldwide, remains a top holding in the portfolio. A core
              investment in Citicorp also has performed well. First-rate
              pharmaceutical companies should benefit the portfolio as the Baby
              Boomers age, so this sector is invested in Bristol-Meyers Squibb,
              Merck, Pfizer and Eli Lilly, among others.
 
                Significant holdings in the energy services sector include
              Halliburton, Schlumberger, Burlington Resources and Smith
              International. Intel, Hewlett Packard and IBM represent the
              largest technology holdings. Davis never loses sight of the fact
              that its 28-year performance has been built as much by avoiding
              the big losers as by picking winners.
 
              ALLIANCE GROWTH -- ALLIANCE CAPITAL MANAGEMENT L.P.
 
                The Alliance Growth Portfolio achieved a 13.58% return during
              the reporting period. The portfolio's strong performance was
              attributable to significant overweights in both the Technology and
              Financial sectors as well as superior stock selection within those
              sectors and throughout the portfolio in general. Particular
              contributors to performance included Dell Computers, Compaq,
              Microsoft, Applied Materials, Merrill Lynch, MBNA and Dean Witter
              Discover. The portfolio in the aggregate continues to offer
              superior relative earnings momentum.
 
              GROWTH/PHOENIX INVESTMENT COUNSEL
 
                For the six-month period ended May 31, 1997, the Growth/Phoenix
              Investment Counsel Portfolio posted a 6.90% return. In retrospect,
              portfolio performance was dampened by lower-than-market weighting
              to large-cap issues. While many large-cap stocks are held in this
              portfolio, it also contains many mid-cap issues with rapid growth
              prospects, which the market did not reward as highly. Sectors in
              which the portfolio performed well during the reporting period
              included consumer staples, financials and health care. Areas of
              underperformance included technology -- which, outside the largest
              companies, continues to be challenging despite excellent growth
              prospects -- basic materials and energy stocks.
 
              PUTNAM GROWTH -- PUTNAM INVESTMENT MANAGEMENT, INC. ("PUTNAM")
 
                This portfolio returned 7.39% for the six months ended May 31,
              1997. Putnam made some strategic shifts in portfolio weightings
              during the reporting period. Chief among these shifts was the
              significant addition to financial services stocks. Fueling the
              move was Putnam's expectation that interest rates would remain
              low, as well as the many growth opportunities evolving in the
              financial sector because of deregulation. Health care was another
              sector favored by Putnam, primarily on the basis of a strong flow
              of new products to market following a period of intensive spending
              on research and development.
 
              AGGRESSIVE GROWTH -- SUNAMERICA ASSET MANAGEMENT CORP.
 
                The Aggressive Growth Portfolio posted a -2.52% return for the
              six months ended May 31, 1997. The portfolio's performance
              compares favorably with that of portfolios

              managed by other small cap growth managers, and compares
              unfavorably with value or larger cap managers. However, SAAMCO
              expects smaller growth to start outperforming the value or larger
              cap areas as the economy slows and more investors begin to search
              for growth names.
 
                The portfolio's investments span many sectors, including
              financial services which is benefiting from improved savings and
              investments rates, as well as low inflation and sector
              consolidation. Technology, including semiconductors and equipment
              hardware, software datacom and telecom equipment, represents about
              30% of the portfolio's holdings, reflecting SAAMCO's prediction
              that business in various sectors would improve and that the
              Russell 2000 rebalancing would increase the index weighting of
              technology. Larger holdings in the sector include Corning, Lucent
              Technologies and Remec.
 
              GLOBAL EQUITIES -- ALLIANCE CAPITAL MANAGEMENT L.P.
 
                The Global Equities Portfolio achieved performance of 9.75% for
              the six-month period ended May 31, 1997. At the country level, the
              portfolio benefited from overweighted positions in the U.S.,
              Switzerland and the Netherlands relative to the benchmark, as well
              as superior relative stock selection in the U.S., Japan and
              Europe. Overweighted stocks appreciating in excess of 20% for the
              six-month period included Novartis, ING Group, Fortis Amev,
              Smithkline Beecham, Rohm, Woolworths, and Berjaya Group.
 
                No dramatic shifts occurred during the reporting period in
              either industry or sector allocation. The portfolio continued to
              emphasize companies offering strong earnings and fundamental
              momentum and value, with many of those residing in the financial,
              technology, consumer services, and consumer staples sectors.
 
              INTERNATIONAL DIVERSIFIED EQUITIES -- MORGAN STANLEY ASSET
              MANAGEMENT INC.
 
                For the six-month period ended May 31, 1997, the International
              Diversified Equities Portfolio posted a return of 5.02%. According
              to MSAM, Japan's market rebounded from an early year slump,
              leading to relatively good overall performance. MSAM's decision to
              tilt out of the banking sector was positive for the portfolio's
              relative results due to the bank sector's significant
              underperformance. Country allocations to Spain and Germany were
              likewise positive for performance, as was the decision to
              eliminate positions in Malaysia, which is facing a large current
              account deficit and the potential for real estate problems. An
              underweight in Switzerland detracted from returns.
 
                MSAM expects to see an upswing in Asia as global economic growth
              picks up. Although Singapore was basically flat for the period,
              the country should benefit from recent strength in the yen and
              global electronics demand, while Hong Kong seeks to benefit from
              investor interest in China and a fairly smooth handover. In
              Thailand, continuing pressure regarding financial institutions and
              currency will keep the manager on a cautious watch, despite
              compelling valuations there. Going forward, the manager believes
              EMU tensions and uncertainty continue to favor the strengthening
              of the U.S. dollar vs. the deutsche mark bloc, and has hedged the
              deutsche mark accordingly.
 
                As we enter the second half of 1997 with the money managers in
              varying degrees of conservative optimism, it's important to keep
              in mind that investing over the long term is as critical to
              building your Personal Retirement Portfolio(TM) as are your
              investment selections and how market fluctuations change the value
              of those selections. Our money

              All portfolio performance is reported at the underlying trust
              level, which includes investment management annual expenses but
              does not include charges or fees at the variable annuity level.
              Past performance is no guarantee of future results.
 
              Investments in stocks and bonds are subject to risk, including
              stock market and interest rate fluctuations. Investments in
              non-U.S. stocks and bonds are subject to additional risks,
              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. Mortgage-backed
              securities are subject to prepayment, which can result in
              reinvestment of principal at lower yields. Investment in
              securities related to gold or other precious metals and minerals
              are considered speculative and are impacted by a host of worldwide
              economic, financial and political factors. 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 (UNAUDITED)
 
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.
 
  The Trust issues 18 separate series of shares ("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 Corporate Bond Portfolio seeks a high total return with only moderate price
risk by investing primarily in investment grade fixed-income securities.
 
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 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 Alliance Growth, Growth/Phoenix Investment Counsel and Putnam Growth
Portfolios (formerly, the Provident Growth Portfolio) 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 Aggressive Growth Portfolio seeks long-term growth of capital through
investment primarily in equity securities of small capitalization growth
companies.
 
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 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.
 
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 May 31, 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. 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 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.
Upon 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.
 
                                                           ---------------------
 
                                       111
<PAGE>   113
 
  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 its 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 were not
affected.

book/tax differences resulted in increases (decreases) to the components of net
assets as follows:

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 May 30, 1997, the Cash Management, High-Yield Bond,
SunAmerica Balanced, and Aggressive Growth Portfolios had a 20.4%, 4.1%, 5.7%
and 10.1%, undivided interest, respectively, which represented $13,851,000,
$2,798,000, $3,891,000 and $6,860,000, 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, 5.45% dated 5/30/97, in
the principal amount of $67,813,000 repurchase price $67,843,798 due 6/2/97
collateralized by $73,520,000 U.S. Treasury Notes 6.50% due 11/15/26,
approximate aggregate value $69,247,018.
 
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 book purposes, (which approximates tax basis), including
short-term securities at May 31, 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:
