              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.
 
   
                As you may be aware, we introduced an exciting new portfolio to
              the Polaris series of variable annuities earlier this year. With
              its focus on finding value among big-name, blue-chip companies,
              the "Dogs" of Wall Street Portfolio is a powerful addition to the
              SunAmerica Series Trust and has been available in most states
              since April 1, 1998. The portfolio is managed by SunAmerica Asset
              Management Corp., a well-regarded investment management firm that
              also manages several other investment options within the trust.
              For investors seeking the strong growth potential of equities who
              also want the reassurance of investing in blue-chip companies, the
              "Dogs" of Wall Street Portfolio may be worth considering. (Note:
              "Dogs" of Wall Street was not available in New York as of the date
              of this report.)
    
 
   
                To give you a better understanding of economic conditions over
              the six months ended May 31, 1998 and how these conditions
              affected the financial markets, we have provided comments and a
              combined perspective from eight of the money managers in the
              Polaris series (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). Also included
              are performance summaries of each portfolio, as well as insight
              into some of the strategies used by the portfolio managers in
              today's market environment.
    
 
              THE SIX MONTHS IN REVIEW
 
              U.S. Economy
 
                Perhaps the most surprising aspect of the first half of 1998 was
              the overall strength of the U.S. economy, despite the worsening
              Asian economic and financial crisis. Even with the slowing demand
              for exports and sagging commodity prices, the U.S. economy was
              still robust, with first-quarter real growth in Gross Domestic
              Product (GDP) at an impressive 5.4%. SunAmerica Asset Management
              Corp. ("SAAMCo") believes that this strong GDP growth reflects the
              continued transition of the U.S. from a manufacturing-based
              economy to a service-based economy. This transition should foster
              increased competition and keep inflation low. In addition, the
              vibrant growth rates were backed by a confident consumer enjoying
              higher income and outstanding asset appreciation, especially in
              stocks, bonds, and real estate.
 
                With inflation below 2%, declining interest rates, and continued
              concerns about the Asian economic turbulence, the Federal Reserve
              Board maintained a "wait-and-see" posture on short-term rates.
              Benign inflation and some of the lowest interest rates in decades
              spurred record rates of home sales and mortgage refinancing. The
              remarkable rise in U.S. stocks also boosted household wealth and
              cut the cost of equity capital. In response, both consumer and
              investment spending surged.
 
                Corporate profits were up 6.5% for the first quarter of
              1998 -- still strong, but the lowest profit growth since the
              fourth quarter of 1991. SAAMCo asserts, "Corporate earnings will

              be down from the double-digit gains we saw in 1997, but they are
              quite acceptable given the fact that we are in the eighth year of
              this economic expansion."
 
                The consensus among the money managers in the SunAmerica Series
              Trust is that the U.S. economy will gradually slow as the year
              progresses. Goldman Sachs says, "Renewed turmoil in Asia, coupled
              with sizable inventory retrenchment, should lead to a slowdown in
              the U.S. growth pace." Both SAAMCo and Phoenix Investment Counsel
              concur, pointing out that the effects of the Asian financial
              crisis and the lack of labor will be a drag on U.S. businesses,
              especially if companies refuse "to pay up" for labor in a tight
              market. SAAMCo expects second-quarter GDP growth in 1998 to be in
              the 2.5% to 3.0% range.
 
              U.S. Stock Market
 
                The U.S. stock market continued to reward investors handsomely
              over the six months ended May 31, 1998. The Standard & Poor's 500
              Composite Index, a broad gauge of U.S. stocks, gained an
              impressive 15.06% for the period. Healthcare and consumer cyclical
              stocks led the market, while the energy and transportation sectors
              brought up the rear. The divergence between large- and small-cap
              stock performance widened as investors sought the earnings
              stability and liquidity of blue-chip companies. SAAMCo notes, "As
              always in periods of uncertainty (e.g., the Asian crisis), there
              is a flight to larger-cap, blue-chip securities even though the
              fundamentals of domestically based emerging growth companies
              remain robust."
 
   
                Looking ahead, the SunAmerica Series Trust equity money managers
              remain optimistic about U.S. stocks, although there is some
              concern about the impact of the Asian crisis and the high
              valuation levels. Putnam Investment Management offers this
              assessment: "While the economic backdrop of benign inflation, low
              interest rates, and generally stable earnings growth remains
              positive for U.S. equities, valuations have been pushed higher as
              a result of the strong bull market. The greatest threat to the
              U.S. equity market comes from potential earnings growth weakness."
              Phoenix Investment Counsel adds that, with the earnings
              uncertainties caused by the Asian crisis, there may be increased
              price volatility in the months ahead. However, all the managers
              stress the importance of maintaining a long-term perspective that
              can help investors weather any short-term market fluctuations.
              Davis Selected Advisers sums it up best: "We have a long-term
              perspective because we always want to remember that we are
              investing in a marathon -- more or less as continuous
              investors -- not in a sprint."
    
 
              U.S. Bond Market
 
                Low interest rates and subdued inflation bolstered the U.S. bond
              market during the six months ended May 31, 1998. During the
              reporting period, the Lehman Brothers Aggregate Index, which
              represents the broad U.S. fixed income market, returned 4.09%.
 
                News from abroad had a major impact on U.S. bond prices. Recent
              reports from Asia show the region sliding deeper into recession
              with the Japanese GDP falling at a dramatic 5.3% annualized rate
              in the first quarter of 1998. The Asian financial crisis aided the
              U.S. bond market, especially U.S. Treasuries, as investors moved
              money out of international and commodities markets and into less
              volatile securities. Mortgage-backed and corporate bonds also
              benefited as investors looked for yield and added price stability.
              High-yield bond returns remained strong, but like equities, they
              experienced volatility due to the Asian crisis.

- ---------------------
 
                Given the expectation of a moderating U.S. economy and the
              current unrest in Asia, SAAMCo believes that the Federal Reserve
              Board will hold short-term rates at 5.5% for the next several
              months -- a trend that should boost the performance of bonds.
              Goldman Sachs echoes this sentiment, but cautions, "Risks to our
              outlook depend heavily on developments abroad. In particular,
              economic collapse in Japan could cause weaker growth, with
              potentially negative effects on equity and bond values, as well as
              domestic spending. In contrast, if Asia stabilizes quickly, then
              the U.S. economy could take center stage, increasing the risk of
              monetary policy tightening later in 1998."
 
              Global Market
 
                The six months ended May 31, 1998 saw a significant imbalance in
              the global economic environment -- continued strong growth in the
              U.S., an ongoing recovery in Europe, and further downward spirals
              in Asia and Japan. European countries enjoyed robust economic
              growth during the period, fueled by an environment of modest
              inflation, low interest rates, and the emergence of European
              Monetary Union (EMU). Countries on the periphery of the impending
              EMU zone experienced the greatest growth, as local interest rates
              continued to converge downward. Corporate restructuring remains a
              key driver of surprisingly strong European equity performance.
 
                In contrast, Pacific Basin economies remained in turmoil. Early
              in the year, the situation appeared to stabilize following a South
              Korean bailout package sponsored by the International Monetary
              Fund (IMF). However, deterioration of the Japanese economy,
              political instability in Indonesia, and other localized problems
              continued to restrain the Asian markets.
 
   
                Goldman Sachs believes that the plummeting Japanese yen has
              become a focal point for a potential recovery in Asia. A weaker
              yen could trigger competitive currency devaluations by China and
              other Asian countries. Goldman Sachs predicts, "The world will be
              watching as Japan tries to stabilize the yen and formulate a
              recovery plan. Should the Japanese government disappoint, the
              repercussions will be severe for the yen as well as for other
              Asian currencies and stock markets. If positive steps are taken to
              stimulate consumer demand and restructure the bad debt that
              plagues Japan's banks, they may mark a turning point in the Asian
              crisis."
    
 
   
                In Europe, Putnam Investment Management, Morgan Stanley Asset
              Management, and Alliance Capital Management all see continued
              economic growth and other positive trends stemming from the
              development of a common European currency. Putnam notes that EMU
              is "a boon not only to core Europe, but also to peripheral markets
              such as Portugal, Greece, Hungary, and Poland." On a wider scale,
              Putnam believes that many emerging markets represent attractive
              opportunities at the current price, economic growth, and valuation
              levels. Shares have fallen to historic lows, and more than reflect
              the sober environment in markets such as Asia, Russia, and the
              Indian subcontinent.
    
 
                For 1998, Morgan Stanley Asset Management is forecasting growth
              of 2.3% for the industrialized world, coupled with a very benign
              inflation environment of 1.5%. Morgan Stanley expects the global
              economy to continue to diverge between expansions in both the U.S.
              and Europe (3.5% and 2.6% respectively) and possible recession in
              Japan and Asia.

              PORTFOLIO PERFORMANCE SUMMARIES
 
              Cash Management Portfolio (SunAmerica Asset Management Corp.)
 
                The Cash Management Portfolio performed competitively for the
              six-month period ended May 31, 1998, with a return of 2.47%. The
              positive performance reflected SAAMCo's strategy to maintain a
              slightly longer average maturity of 65 days, versus the Donaghue
              average of approximately 55 days. The portfolio benefited as
              interest rates remained in a stable-to-declining environment over
              the reporting period.
 
   
              Global Bond Portfolio (Goldman Sachs Asset Management
              International)
    
 
                The Global Bond Portfolio returned 5.39% for the six months
              ended May 31, 1998. This compares to the 2.91% return of the
              Lipper Global Income universe. One of the major contributors to
              the portfolio's positive performance was the strong exposure to
              Danish and U.K. issues, two markets that benefited greatly from
              favorable interest rate and economic conditions. Another factor
              that affected performance was the continuing decline of bond
              yields in Japan. As of May 31, 1998, the yield for the benchmark
              government bond was at a historic low of 1.20%. Credit conditions
              in Japan tightened with sharp declines in bank lending, while
              unemployment and business inventories continued to climb, an
              indication that economy activity may fall even further. With
              yields trending lower, Goldman Sachs continues to maintain an
              exposure to the Japanese market.
 
   
              Corporate Bond Portfolio (Federated Investors)
    
 
   
                With relatively stable interest rates and solid corporate
              fundamentals, corporate bonds outperformed U.S. Treasury
              securities with similar maturity. The Corporate Bond Portfolio
              took advantage of these conditions, posting a 4.18% return for the
              six months ended May 31, 1998. The portfolio also benefited from
              the strong performance of high-yield corporate securities, which
              comprised approximately 25% of total assets. This significant
              exposure to high-yield issues helped generate not only an
              above-average income distribution, but also enhanced price
              appreciation, as high-yield corporate bonds were among the top
              performers in the fixed income market.
    
 
              High-Yield Bond Portfolio (SunAmerica Asset Management Corp.)
 
                With a return of 7.28% for the six-month period ended May 31,
              1998, the High-Yield Bond Portfolio was among the top performers
              in its peer group. According to Lipper Analytical Services, an
              independent research firm, the average high-yield portfolio
              returned 5.6%, while the Merrill Lynch High Yield Index returned
              4.98%.
 
                The portfolio remained overweighted in the telecommunications
              sector, while limiting its exposure to the gaming and retailing
              industries. During the reporting period, SAAMCo slightly increased
              the portfolio's holdings in the cyclical sector (paper, steel, and
              chemicals). Strong performers over the six-month period included
              Dominion Textile, Intermedia Communications and Verio Units.
              Negating some of these gains was weakness in the bond prices of
              Ionica and Southwest Royalties.

              Worldwide High Income Portfolio (Morgan Stanley Asset Management
              Inc.)
 
                During the six months ended May 31, 1998, the Worldwide High
              Income Portfolio generated a return of 6.33%, versus 5.25% for the
              blended benchmark (weighted 50% J.P. Morgan Emerging Markets Bond
              Index Plus and 50% C.S. First Boston High-Yield Index).
 
                During the reporting period, Morgan Stanley Asset Management
              continually adjusted the portfolio's exposure to the emerging
              markets and Russia in particular based on market trends and
              forecasts. When prices were particularly volatile, the portfolio
              manager shifted assets from the emerging markets to U.S.
              high-yield securities. As valuations improved, Morgan Stanley
              Asset Management moved back into the emerging markets sector and
              established an overweight position in Russia and Mexico.
 
              SunAmerica Balanced Portfolio (SunAmerica Asset Management Corp.)
 
                The SunAmerica Balanced Portfolio continued its strong
              performance during the six months ended May 31, 1998. The
              portfolio was a top performer in its class, with a total return of
              12.21% for the reporting period. The portfolio benefited from its
              significant equity exposure to the financial, healthcare, and
              consumer cyclical sectors, all of which performed well for the six
              months. As of May 31, 1998, the portfolio's largest equity
              holdings were Warner-Lambert Co., Summit Bancorp, General Electric
              Co., Wells Fargo & Co., and Lucent Technologies, Inc.
 
                SAAMCo continues to focus on sectors where it anticipates
              consistent, double-digit earnings growth -- in particular, the
              financial, pharmaceutical, and technology industries. During the
              reporting period, SAAMCo added to its consumer cyclical holdings,
              with names like Home Depot, Wal-Mart, and Dayton Hudson. The
              portfolio manager believes that these sectors represent good value
              and will outperform as the price of the underlying commodity
              recovers.
 
   
              Balanced/Phoenix Investment Counsel Portfolio
              (Phoenix Investment Counsel, Inc.)
    
 
                The Balanced/Phoenix Investment Counsel Portfolio posted a solid
              gain of 9.06% for the six-month period ended May 31, 1998, while
              its benchmark index earned 9.93% (the benchmark is weighted 55%
              S&P 500 Index, 35% Lehman Brothers Aggregate Bond Index, and 10%
              Salomon Brothers 3-Month Treasury Bill Index). Phoenix continues
              to maintain a strong equity position in healthcare, technology,
              and communications services, all of which helped to boost
              performance. The portfolio manager took advantage of the surge in
              financial services stocks to take profits in this sector. In
              regard to fixed income securities, the portfolio is
              well-diversified, with an average credit quality of "AA," a
              duration of approximately 4.9, and issues ranging from municipal
              to government bonds.
 
              Asset Allocation Portfolio (Goldman Sachs Asset Management)
 
                The Asset Allocation Portfolio posted a return of 7.09% for the
              six months ended May 31, 1998, compared to the 4.09% return of the
              Lehman Brothers Aggregate Index and the 8.81% return of the Lipper
              Flexible Portfolio Variable Annuities universe. The equity market
              remained robust, but performance was driven primarily by a run-up
              in mega-cap stocks. The portfolio's bias towards mid-cap stocks
              affected performance during the
 
                                                           ---------------------

              reporting period. However, Goldman Sachs believes that many of the
              big names are now overvalued and do not exhibit the currently
              strong fundamentals of mid-cap stocks.
 
                Goldman Sachs continues to focus on value, seeking well-managed
              companies that are currently selling at a discount but whose
              prices can rebound over time. For example, the portfolio holds RJR
              Nabisco, a tobacco company that has suffered price declines due to
              the many legal challenges and expected regulatory changes facing
              the industry. Goldman Sachs believes that once these uncertainties
              are resolved, shareholders with a long-term horizon will be
              rewarded.
 
              Utility Portfolio (Federated Investors)
 
                With low interest rates, the Utility Portfolio performed well,
              returning 8.60% for the six months ended May 31, 1998. Given the
              attractive valuations of utilities and an overall stock market
              that is arguably the most expensive ever, Federated continues to
              favor domestic utilities. The defensive characteristics of
              electric companies combined with their improving fundamentals,
              along with those of gas and telecommunications firms, provide
              excellent prospects relative to the overall market.
 
                Overall, Federated's current strategy focuses on the following
              themes: utilities with skilled management who can capitalize on
              unprecedented changes in the industry; domestic utilities that are
              generating strong cash flows; undervalued domestic utilities with
              high dividend yields; and defensive non-utility issues (e.g., real
              estate investment trusts) that can provide relative safety in a
              market decline. As of May 31, 1998, the portfolio was allocated as
              follows: domestic utilities (81%), foreign utilities (2%), non-
              utilities (15%), and cash equivalents (2%).
 
              Growth-Income Portfolio (Alliance Capital Management L.P.)
 
   
                The Growth-Income Portfolio appreciated 15.82% for the six-month
              period ended May 31, 1998. The portfolio benefited from both
              strong stock selection and overweighted positions in the consumer
              services, healthcare, and financial sectors. Stocks that boosted
              returns included Merrill Lynch, Dayton Hudson, Home Depot,
              Wal-Mart, Pfizer, Dell, and Cisco. As of May 31, 1998, the top ten
              names in the portfolio were General Electric (3.7%), Coca Cola
              (3.5%), Wal-Mart (2.6%), Pfizer (2.5%), Merck (2.4%), Bristol
              Myers Squibb (2.3%), Procter & Gamble (2.2%), Disney (2.0%), Cisco
              (1.9%), and Philip Morris (1.8%). The portfolio was broadly
              diversified across 96 stocks and 10 economic sectors, with
              financials, consumer services, consumer staples, technology, and
              healthcare representing approximately 67% of the portfolio's
              market value.
    
 
              Federated Value Portfolio (Federated Investors)
 
                With a return of 16.02% for the six months ended May 31, 1998,
              the performance of the Federated Value Portfolio was quite strong.
              The portfolio's value focus aided performance in December when
              investors became concerned about the Asian financial crisis and
              how it might affect the global markets. However, the value style
              has worked against the portfolio in recent months, with most
              investors favoring mega-cap growth stocks such as Microsoft and
              G.E.
 
                One sector that contributed greatly to the solid returns was the
              consumer cyclical industry. For example, two stocks in the
              portfolio, K-Mart and Wal-Mart, are up 68% and
- ---------------------

- ---------------------
 
              34%, respectively, so far this year. Other industries that
              provided winning returns included the transportation and financial
              sectors.
 
              Venture Value Portfolio (Davis Selected Advisers, L.P.)
 
                The Venture Value Portfolio delivered a total return of 10.10%
              for the six-month period ended May 31, 1998, versus a return of
              15.06% for the Standard & Poor's 500 Composite Index.
 
                In the first quarter of 1998, Davis Selected Advisers increased
              the portfolio's exposure to McDonald's which is now one of the
              largest holdings in the portfolio. Financial, technology and
              energy-related stocks continued to dominate the portfolio. The
              portfolio added more shares of insurer General Re, making it the
              largest holding. Shares of Citicorp were also added. In the
              technology sector, Davis bought Applied Materials, Inc. and
              increased its positions in Hewlett-Packard Co. and Texas
              Instruments, Inc. As for energy-related stocks, shares were added
              to existing positions in Schlumberger and Haliburton.
 
              "Dogs" of Wall Street Portfolio (SunAmerica Asset Management
              Corp.)
 
                The "Dogs" of Wall Street Portfolio is a new portfolio in the
              SunAmerica Series Trust, introduced on April 1, 1998. The
              portfolio seeks total return through a combination of capital
              appreciation and current income. It follows a disciplined
              value-oriented approach by investing in large, blue-chip stocks
              that are undervalued in the current market as measured by high
              dividend-to-stock-price yield ratios. From the portfolio's
              inception on April 1, 1998 to May 31, 1998, the portfolio had a
              total return of -2.60%
 
              Putnam Growth Portfolio (Putnam Investment Management, Inc.)
 
                From November 30, 1997 through May 31, 1998, the Putnam Growth
              Portfolio returned a competitive 15.65%. Contributing to the
              portfolio's double-digit gains were the finance and consumer
              cyclical sectors. Strong performance from the portfolio's
              healthcare and technology holdings, where Putnam focused on
              computer software over semiconductors, also boosted returns.
 
                While the economic backdrop remains positive for U.S. equities,
              valuations have been pushed higher as a result of the strong bull
              market. The greatest threat to the U.S. equity market comes from
              potential earnings growth weakness. However, with inflation and
              interest rates near historic lows, the long-term outlook remains
              favorable. Putnam's strategy continues to focus on finding
              high-quality growth stocks using both quantitative and fundamental
              research, combined with rigorous risk management techniques.
 
   
              Growth/Phoenix Investment Counsel Growth Portfolio
              (Phoenix Investment Counsel, Inc.)
    
 
                The Growth/Phoenix Investment Counsel Portfolio posted a
              double-digit gain of 12.68% for the six-month period ended May 31,
              1998. During the same reporting cycle, the Standard & Poor's 500
              Composite Index earned 15.06%. Positive contributors to
              performance included the portfolio's overweighted position in the
              "red-hot" healthcare sector as well as strong stock selection in
              capital goods and consumer staples. Individual holdings which
              produced stellar gains included Pfizer, Chancellor Media, Tyco
              International, BMC Software and Home Depot. On the other side of
              the equation, stocks that weakened
                                                           ---------------------

- ---------------------
 
              performance included many of the portfolio's energy holdings and
              some technology issues.
 
              Alliance Growth Portfolio (Alliance Capital Management L.P.)
 
                The Alliance Growth Portfolio appreciated an impressive 23.85%
              for the six-month period ended May 31, 1998. Superior stock
              selection was the most significant determinant of performance.
              Significant exposure to the financial, consumer services,
              technology, and healthcare sectors also contributed positively to
              portfolio performance, with those four sectors representing 73% of
              the portfolio's market value on May 31, 1998. Top-performing
              holdings during the period included Liberty Media, Carnival
              Cruise, Dayton Hudson, Home Depot, Kohls, Wal-Mart, Pfizer,
              Schering-Plough, Merrill Lynch, Morgan Stanley Dean Witter, MBNA,
              Lucent, Nokia, Microsoft, and Cisco. The portfolio currently holds
              a total of 54 stocks.
 
              Global Equities Portfolio (Alliance Capital Management L.P.)
 
                The Global Equities Portfolio returned 18.21% for the six months
              ended May 31, 1998. Strong stock selection and a limited exposure
              to Japan and other Asian markets were major factors affecting
              portfolio performance. The portfolio's selection of European
              cyclical growth stocks, including Nokia Oyj, Philips, Schneider,
              Alcatel, and Henkel, helped to enhance returns. Financial and
              defensive stocks in Europe were also clear winners, with Nestle,
              ING, and Bank Austria contributing positively to performance.
              Within the U.S. component of the portfolio, consumer services,
              particularly in the retail industry, were big gainers. These
              included Home Depot, Staples, Dayton Hudson, and TJX. Regional
              exposures on May 31, 1998 were as follows: the Americas (47.43%),
              Europe/U.K. (36.91%), Japan (9.90%), and the Pacific Basin and
              Asia ex-Japan (1.96%).
 
              International Growth & Income Portfolio (Putnam Investment
              Management, Inc.)
 
                For the six months ended May 31, 1998, the International Growth
              and Income Portfolio gained 19.46% in U.S. dollars versus 16.06%
              for the Morgan Stanley Capital International (MSCI) Europe,
              Australia and Far East (EAFE) Index.
 
                Strong equity performers included Vivendi, formerly known as
              Generale des Eaux, a global water and telecommunication utility in
              France, which gained 56% on the strength of a successful
              restructuring; Kao, a leading personal-care products company in
              Japan, which advanced 22% amid the launch of new products and a
              recent reorganization; and ING, a Dutch banking and insurance
              conglomerate, which advanced 81% on the strength of its merger
              with the leading Dutch insurance company and second-largest Dutch
              bank, as well as the subsequent acquisitions of Barings, Inc. and
              Banque Bruxelles Lambert.
 
   
              International Diversified Equities Portfolio
              (Morgan Stanley Asset Management Inc.)
    
 
                For the six-month period ended May 31, 1998, the International
              Diversified Equities Portfolio outperformed the Morgan Stanley
              Capital International (MSCI) Europe, Australia and Far East (EAFE)
              Index, 19.80% versus 16.06%. The single largest contributor to the
              portfolio's above-average performance was its significant
              underweight positions in Japan, Hong Kong, Singapore, and
              Malaysia. Rather than focusing on Asia, Morgan Stanley

- ---------------------
 
              Asset Management shifted a significant portion of the portfolio's
              assets to Europe. The portfolio benefited greatly from this move,
              especially from investments in Italy and Spain. Hedging most of
              the portfolio's exposure to the Japanese yen was also beneficial,
              as the U.S. dollar appreciated against the yen during the
              reporting period.
 
              Real Estate Portfolio (Davis Selected Advisers, L.P.)
 
   
                The Real Estate Portfolio posted a return of -1.86% for the
              reporting period ended May 31, 1998, compared to an average annual
              return of -1.98% for the Lipper real estate category. One company
              that Davis Selected Advisers favors now is Boardwalk Equities, a
              small Canadian company that owns apartments primarily in Calgary
              and Edmonton, two strong apartment markets. Davis remains bullish
              on Centerpoint Properties, a Chicago-based real estate investment
              trust (REIT) that owns industrial space; Starwood Lodging, a
              long-time favorite that has substantial upside potential as the
              firm digests the billions of dollars of acquisitions it has made
              in the last several years; and Vornado, a diversified REIT that
              owns office buildings in Manhattan, as well as many shopping
              centers and cold storage facilities.
    
 
              Aggressive Growth Portfolio (SunAmerica Asset Management Corp.)
 
                With investors growing increasingly concerned about the impact
              of Asia on the U.S. financial markets, a "flight to quality"
              occurred in early 1998. Equity investors sought large, blue-chip
              securities that offered greater price stability than small-cap
              stocks. As a result, the Aggressive Growth Portfolio experienced a
              difficult period, posting a return of 2.64% for the six months
              ended May 31, 1998.
 
                The portfolio carried an above-average cash position for most of
              the six months. However, near the end of the period, SAAMCo began
              to reduce its cash position and selectively add to its small-cap
              holdings on a stock-by-stock basis. During the most recent
              quarter, SAAMCo also restructured the portfolio. The number of
              stock holdings were reduced in an attempt to focus more on
              industry leaders and trendsetters. In addition, SAAMCo shifted
              some assets from the technology sector into the consumer cyclical
              sector. After seven years of relative underperformance, SAAMCo
              believes that many specialty retailers offer excellent value while
              experiencing renewed growth. These investments range from the
              carpet consolidator, Mohawk Industries, to specialty retailers,
              including Sunglass Hut, Abercrombie & Fitch, Oakley, and Movado.
 
              Emerging Markets Portfolio (Putnam Investment Management, Inc.)
 
                For the six months ended May 31, 1998, the Emerging Markets
              Portfolio returned -4.77% in U.S. dollar terms versus a return of
              -7.17% for the Morgan Stanley Capital International (MSCI)
              Emerging Markets Free Index. Emerging markets in Asia returned
              -14.0% for the six-month period, while Latin American issues
              returned -9.0%. In contrast, European countries gained 0.4%.
 
                Some of the best performing stocks were in markets that were
              hardest hit during the period. For example, in Malaysia, portfolio
              return was boosted by an emphasis on defensive, non-index stocks,
              such as PPB Oil Palms (a palm oil producer) and Berjaya Sports
              Toto (a gaming company). Both stocks significantly outpaced the
              Malaysian index. The portfolio's very limited exposure to
              Indonesia was another positive factor, as the portfolio avoided
              the significant depreciation in that country's currency. Given the
                                                           ---------------------

- ---------------------
 
              renewed concerns for the Asian economies and the political
              tensions in the subcontinent, Putnam has been shifting country
              weightings toward Latin America and Europe, where the investment
              environment is significantly better.
 
              IN CONCLUSION
 
                As an investor in today's market, you have probably enjoyed the
              outstanding returns of both stocks and bonds. The eight-year bull
              market is now the longest we have experienced since World War II,
              and we have not seen a market decline of greater than 20% since
              1990. In these heady times, it is easy to get accustomed to the
              double-digit returns and make investment decisions based on
              momentum, not on your long-term investment strategy. That is why
              we encourage you to meet with your investment representative at
              least once a year to review your overall portfolio. Your

              remain well-diversified and in line with your long-term goals and
              tolerance for risk.

              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. Investments 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; 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 22 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.

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, 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.
 
  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.
 
  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
- ---------------------
132
<PAGE>   134
 
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.
 
   
ORGANIZATIONAL EXPENSES:  Costs incurred by the Adviser in connection with the
organization and registration of the Trust amounted to $223,826. During the year
ended November 30, 1997 and period ended May 31, 1998, an additional $19,122 and
$4,717, respectively, were incurred as part of the organization and registration
of additional Portfolios. Organizational expenses are amortized on a straight
line basis by each applicable Portfolio of the Trust over the period of benefit
not to exceed 60 months from the date the respective Portfolio commenced
operations.
    
 
3. OPERATING POLICIES:
 
  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.
 
   
  At May 31, 1998, the Aggressive Growth, High Yield Bond, Cash Management,
SunAmerica Balanced and "Dogs" of Wall Street Portfolios had a 12.6%, 5.4%,
4.4%, 3.8% and 0.9%, respectively, undivided interest, representing $18,983,000,
$8,093,000, $6,481,000, $5,799,000 and $1,409,000, respectively, in principal
amount, in a joint repo with PaineWebber, Inc., which is dated May 29, 1998,
bears interest at the rate of 5.50% per annum, has a principal amount of
$151,156,000 and a repurchase price of $151,225,280, matures on June 1, 1998 and
is collateralized by $136,175,000 of U.S. Treasury Bonds, which bear interest at
a rate of 6.75% per annum, mature August 15, 2026 and have an approximate value
of $155,130,560.

                                                                           133
<PAGE>   135
 
  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.
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.
 
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.

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, "Dogs" of Wall Street 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:
