DEAR INVESTOR:

  We are pleased to present our semiannual report for the SunAmerica Series
Trust, one of the underlying trusts for the variable annuities issued by Anchor
National Life Insurance Company and First SunAmerica Life Insurance Company.
Please keep in mind that while several of the SunAmerica life companies' annuity
products have the SunAmerica Series Trust in common as an underlying investment,
not all of the Series' portfolios are available in all of the products.

  To give you a better understanding of economic conditions over the six months
ended July 31, 1999, and how these conditions affected the financial markets, we
have provided comments and a combined perspective from the investment managers
who manage the portfolios in your variable annuity (excluding Wellington
Management Company, LLP, which manages the portfolios in the Anchor Series
Trust, for which you should have received a separate and complete report about
one month ago). 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

  A broad array of economic forces, both in the United States and overseas, seem
to have come together to bring on the economic slowdown people have been
expecting for over a year. MFS Investment Management points out that the
nation's gross domestic product (GDP) slowed to a 2.3% annual rate in the second
quarter -- the slowest growth rate in three years -- marking a major decline
from the 4.3% annual rate seen in the first quarter. This slower growth appears
to have been caused by higher interest rates, higher oil prices and slower
inventory growth, all of which helped dampen the overall economy.

  Despite the slowdown, First American Asset Management asserts that the U.S.
economy remains fundamentally sound and shows none of the imbalances that
typically precede the end of a business expansion. MFS adds that perhaps the
most positive note -- and one that could keep supplying some fuel to the
economy -- comes from the consumer, who accounts for two-thirds of U.S. economic
activity. Davis Selected Advisers, L.P. concurs, saying that although consumer
spending downshifted toward the end of the period, it could help keep the
economy moving ahead -- though at a somewhat slower pace -- for the rest of the
year.

  In light of the global recovery, the Fed tightened monetary policy in June by
slightly raising short-term interest rates in an effort to head off any
incipient inflation. Despite this reversal in monetary policy, SunAmerica Asset
Management Corp. (SAAMCo) believes that the Fed's action was aimed at
extending -- not ending -- the current economic expansion, though further
tightening is possible as the global economic recovery continues. Goldman Sachs
Asset Management is more assertive, forecasting additional tightening this year
and further tightening in 2000.

U.S. Stock Market

  The U.S. stock market experienced a sustained period of high volatility during
the reporting period as market leadership shifted back and forth between size
and style categories. At the beginning of the period, notes Goldman Sachs, the
markets were dominated by a short list of giant growth and technology favorites.
This was followed by a sudden broadening of market leadership as global economic
strength inspired investors to venture into the discounted segments of the
market -- value-oriented, smaller capitalization and economically sensitive
industrial stocks. Toward the end of the reporting period, however, the markets
once again reasserted their preference for large capitalization growth stocks.

  Looking ahead, MFS believes that the fundamental underpinnings of a reasonably
strong market remain. These include not only low inflation and interest rates,
but also continuing efforts by corporate America to
                                                           ---------------------
                                        1
<PAGE>   3

streamline operations, consolidate, and maintain clean balance sheets. Davis
Selected Advisers agrees, and states that there remain many positive forces
affecting both the U.S. economy and stock market. Along with the ongoing
strength of consumer spending, which has been bolstered by rising real income,
lower unemployment, stock market gains, and a relatively low interest rate
environment, corporate earnings continue to be robust, partly due to increasing
real margins. Such strong fundamentals may ultimately lead to continued
long-term equity performance.

  SAAMCo addresses the Year 2000 problem, acknowledging the psychological risk
that Y2K continues to have on this market. Although comfortable with corporate
America's readiness for the new millennium, SAAMCo is wary of the human
response, asserting that Y2K issues are no longer in the hardware but in the
human-ware. The recent pullback in the market following the close of the second
quarter should be viewed as a positive event -- a buying opportunity in an
upward trending market. As investors worry about the direction of the Fed, a
weakening dollar and Year 2000 issues, volatility will continue. The underlying
fundamentals of the U.S. equity market, however, continue to be favorable.

U.S. Bond Market

  During the two years leading up to this semiannual period, the U.S. economy
and capital markets were the primary beneficiaries of the global financial
crisis. According to Federated Investors, deflationary forces caused by
productive overcapacity in Asia allowed bond yields to decline to levels
otherwise inconsistent with the intensity of U.S. domestic economic activity.

  Over the last six months, however, that has changed. Putnam Investments sums
it up this way: global economic growth rebounded, earnings improved, and the
bond market worried about inflation. Morgan Stanley Asset Management agrees and
adds that, while broader economic growth has driven many equity markets to new
highs this year, this news has not been positive for bonds. Economic expansion
in the U.S. coupled with rising commodity prices have led market participants to
speculate that inflation, and therefore bond yields, will pick up.

Global Market

  The outlook for the global economy continued to brighten toward the end of the
semiannual period. To keep the world economy from slipping into synchronized
recession, central bankers cut interest rates more than 150 times since October.
This liquidity fix, observes Federated Investors, had its intended effect: nine
months later, international capital markets have revived and tentative evidence
of recoveries in the real economies of Asia and Latin America is at hand.
Alliance Capital Management L.P. elaborates by noting that a prospective
V-shaped recovery in East Asia, better-than-expected growth in Japan and a quick
drop in Brazilian interest rates bolstered investor confidence, especially in
Europe where it reached near record levels.

  With respect to the world's financial markets, Morgan Stanley Asset Management
notes that foreign stock performance was mixed in the first half of 1999. While
Japan and Asia showed strong gains, a weak Euro and softening economies held
back European stock performance. Emerging market equities were the star
performers during the period. Although Brazil was forced to devalue its
currency, the move had been widely anticipated and priced into emerging markets.
As the situation in Latin America stabilized, emerging market equities began to
soar. Alliance Capital adds that bond yields moved higher across the board in
industrial countries, but not enough to prevent stock prices from posting
additional gains.

  Looking forward, Alliance Capital believes that global growth will strengthen
over the next 6 to 12 months but does not expect that this strengthening will be
explosive or inflationary. Short-term rates should stay relatively low,
providing support for bond and equity prices.

PORTFOLIO PERFORMANCE SUMMARIES

Cash Management Portfolio (SunAmerica Asset Management Corp.)

  By maintaining our disciplined approach of investing in high quality money
market instruments and actively adjusting the portfolio's average maturity, the
Cash Management Portfolio's managers were able to produce competitive yields. A
2.2% return was achieved for the six-month period ended July 31, 1999.

Corporate Bond Portfolio (Federated Investors)

  Over the six months ended July 31, 1999, the fixed-income markets experienced
significant price declines as interest rates rose across the entire maturity
spectrum. The rise in rates was primarily due to stronger economic activity
worldwide along with the Fed's well publicized intention -- and eventual action
in June -- to hike rates.

  Market jitters over the period also caused the high-quality spread sectors
(corporates, mortgages, agencies) to underperform pure U.S. Treasury securities
as spread yields experienced larger absolute increases. Thus, while the
portfolio performed very well within its peer group, absolute total returns were
negative due to higher rates and corporate bond underperformance. For the six
months, the portfolio posted a -2.9% return.

Global Bond Portfolio (Goldman Sachs Asset Management International)

  The Global Bond Portfolio returned -2.7% for the period ended July 31, 1999,
underperforming the J.P. Morgan Global Government Bond Index return of -1.4%. At
July 31, the portfolio had an effective duration of 5.5 years, a gross current
yield of 5.04% and an average maturity of 8.3 years. The portfolio's returns are
attributable to generally poor performance in the global bond markets as yields
continued to rise in most major regions. Notably, the markets ended the
reporting period with positive returns from only the Japanese, Australian and
New Zealand markets.

High-Yield Bond Portfolio (SunAmerica Asset Management Corp.)

  The High-Yield Bond Portfolio's total return for the semiannual period ended
July 31, 1999, was 3.4%, outperforming the Merrill Lynch High-Yield Master Index
return of 0.9%. The first three months of the semiannual period were the
strongest, as the market continued to rebound from last year's oversold prices.
Led by cyclical issues -- and energy in particular -- the high-yield market
maintained a good tone into May. However, rising interest rates through May and
June coupled with a large volume of new supply led to a reversal in the second
half. While this limited total return, the high-yield market, buoyed by high
coupon income, has outperformed most other fixed-income market sectors.

  The portfolio remains overweighted in telecommunication and media/cable bonds,
and positions in the energy and other cyclical areas have been increased to an
even weighting. We continue to find the defensive characteristics of the
media/cable sector particularly appealing. While not offering the total return
potential of past years, we believe these companies will provide an anchor for
the portfolio over the next year.

Worldwide High Income Portfolio (Morgan Stanley Asset Management)

  During the six-month period ended July 31, 1999, the Worldwide High Income
Portfolio returned 8.4%, compared to the blended benchmark (50% First Boston
High-Yield Index and 50% J.P. Morgan Emerging Markets Bond Index Plus) return of
6.1%. For the first half of the year, the portfolio benefited from an
overweighting in Emerging Market Debt (EMD) versus U.S. high yield securities.
While both asset classes outperformed U.S. investment grade securities, the high
current income of EMD produced a positive 8.3% return for the broad EMD market,
with little to no capital appreciation.

  Among our best performers within the U.S. high-yield segment was Nextel
Communications, which continues to exhibit very strong operating results and
whose stock has risen rapidly. Much of the same can be said for another of our
telecommunications companies, RCN. European telecommunications issuers have
                                                           ---------------------
                                        3
<PAGE>   5

also performed well, as have many issuers in the energy industry, which has
benefited from the sharp rise in oil prices.

SunAmerica Balanced Assets Portfolio (SunAmerica Asset Management Corp.)

  The SunAmerica Balanced Assets Portfolio was up 1.5% for the six months ended
July 31, 1999, just under its blended benchmark (55% S&P 500, 35% Lehman
Brothers Aggregate Index, and 10% Treasury Bills), which gained 1.9%. The Fund
continues to benefit from its exposure to the equity market as well as from its
sector allocations. The top five equity holdings in the portfolio at the end of
July were General Electric, Microsoft, IBM, MCI WorldCom, and EMC.

  Since the end of the second quarter, the summer rally has faded to a summer
correction. The signs of excess in the market that have been of concern to many
investors -- especially pertaining to the Internet -- are being wrung out. We
continue to overweight the financials, energy, and certain areas of technology.
Going forward, solid fundamentals, a positive economic outlook and a cooling of
speculation all support our contention that the market will resume its upward
trend. Volatility will continue as investors worry about interest rates, a
weakening dollar, and Y2K.

MFS Total Return Portfolio (MFS Investment Management)

  For the six months ended July 31, 1999, the portfolio provided a total return
of 4.0%, compared to the 1.9% return for the blended benchmark of 55% S&P 500,
35% Lehman Brother Aggregate Bond Index, and 10% Treasury bills. In the first
three months of 1999, the portfolio was hurt by the continued underperformance
of value stocks. Late in March, however, value stocks began to recover, due in
part to second-quarter concerns about inflation.

  In February, we began increasing the portfolio's stock allocation to around
60% of assets because we felt that prices of value stocks had become attractive,
especially given the large gains in growth stocks over the previous year or so.
This increase helped the portfolio when the market began turning toward value
stocks in April and May. We have also increased the portfolio's holdings of
bonds maturing in less than two years because as interest rates rose, prices of
bonds maturing in 10 years or more fell further than prices of shorter-maturity
bonds. However, we have not changed the basic makeup of the bond portfolio,
keeping approximately 45% of fixed-income assets in investment-grade corporates
and 23% in U.S. Treasuries to help limit price volatility.

Asset Allocation Portfolio (Goldman Sachs Asset Management)

  The Asset Allocation Portfolio returned 3.0% during the reporting period,
outperforming its blended benchmark of the S&P 500 Index (60%) and the Lehman
Brothers Aggregate Index (40%), which returned 1.7%.

  As of July 31, 1999, the portfolio's current allocation was overweighted in
stocks with a 64% allocation, underweighted in bonds with a 31% allocation, and
held a minimal position in cash with a 5% allocation. Overall portfolio
allocation closely matches the allocation at the beginning of the reporting
period, which on January 31, 1999, stood at 60% in stocks, 28% in bonds and 12%
in cash.

Utility Portfolio (Federated Investors)

  For the six months ended July 31, 1999, the S&P Communications Index returned
5.9%. The S&P Utility Index returned 4.8%, with electric stocks returning -3.1%
and natural gas stocks up 24.8%. The Utility Portfolio returned 5.8%, and
continues to offer a relatively high dividend yield.

  Telecommunications stocks benefited from surging demand and falling costs.
Sprint was our best performer (+23.9%). Natural gas stocks benefited from rising
gas prices and continued merger activity. Enron (+30.0%) and Wicor(+47.3%) led
our gas holdings, while Illinova was our top electric performer (+37.4%) after
agreeing to merge with Dynegy.

Equity Income Portfolio (First American Asset Management)

  For the semiannual period ended July 31, 1999, the Equity Income Portfolio
posted a 4.5% gain, matching the return for the S&P 500 Index.

  A significant overweighting in the outperforming energy sector, and the
portfolio's cyclical holdings, have been among the strongest contributors to
performance this year. The portfolio also benefited from strong performance in
the communications services, energy, consumer cyclical and healthcare sectors.
In the communications services sector, Deutsche Telekom and Sprint performed
well. Intimate Brands was a particularly good performer in the consumer cyclical
sector on strong sales and earnings growth, as well as expansion in the earnings
multiple.

  While the S&P 500 healthcare sector underperformed, the portfolio's holdings
in Pfizer, Pharmacia & Upjohn, Johnson & Johnson and Merck all outperformed the
average. The portfolio's weighting in the technology sector was the most
important factor in the quarter's underperformance versus the S&P 500. However,
the position was consistent with the portfolio's strategy of emphasizing
dividend-paying stocks -- few tech stocks pay dividends.

Equity Index Portfolio (First American Asset Management)

  The Equity Index Portfolio posted a 1.9% return during the six months ended
July 31, 1999, underperforming the S&P 500 Index's return of 4.5%.

  While the first half of the period's performance was driven by a select few
large cap growth stocks, the second half saw a broadening of the market. Small
cap stocks and mid-caps both outperformed the S&P 500 Index, with most of the
relative outperformance occurring in April and May. Attractive valuations in the
small- and mid-cap stocks, strong fundamentals, favorable relative earnings
growth rates and a strong economy were the drivers that tuned investors into
these out-of-favor asset classes.

  For the last three months, basic materials, capital goods, communication
services and energy stocks were the top-performing sectors in the S&P 500 Index.
Healthcare stocks were the worst performers as the market showed concern over
the sector's extended valuations.

Growth-Income Portfolio (Alliance Growth Management L.P.)

  The Growth-Income Portfolio achieved returns of 6.9% for the semiannual
period, outperforming the S&P 500 at 4.5%. The portfolio benefited from
overweighted positions in a number of outperforming industries including oil
services, wireless telecommunications, telephones, media, and home products.
Stock selection was also positive, with IBM, Noble Drilling, Honeywell,
Citigroup, Circuit City Stores, Allied Signal, Solectron, and AT&T Liberty Media
contributing meaningfully to performance during the period.

  The portfolio continues to be broadly diversified, with sector exposures and
underlying fundamental attributes comparable to those of the S&P 500. The
Growth-Income Portfolio held 103 stocks as of July 31, 1999, with the top ten
(Microsoft, General Electric, Cisco, Bristol Myers Squibb, Citigroup, IBM,
Walmart, Intel, Schering Plough, and Bank America) accounting for 25% of the
portfolio's market value.

Federated Value Portfolio (Federated Investors)

  The equity markets provided another solid period of returns for the six-month
period with the S&P 500 returning 4.5%. Aided by an improvement in market
breadth starting in April, the Federated Value Portfolio returned 6.7%. This
rotation in April benefited areas of the market such as cyclicals and smaller
capitalization stocks, which have been left behind during the "nifty fifty"
market of the last three years.

  The only major strategic change in the portfolio has been to build its
financials exposure to an overweighted position, more in line with our value
peers. After 18 months of underperformance, this sector looks attractive on our
valuation disciplines and seems poised for a recovery.

                                                           ---------------------
                                        5
<PAGE>   7

Venture Value Portfolio (Davis Selected Advisers, L.P.)

  For the past six months, the Venture Value Portfolio outperformed the S&P 500
Index, with a total return of 8.9% versus the benchmark's 4.5%. This performance
was driven by strong returns among the portfolio's top holdings, which are
weighted toward large cap, diversified technology and financial companies.

  In particular, Hewlett Packard, American Express, Texas Instruments, IBM, and
Citigroup posted returns of approximately 20% or better. Philip Morris, a
notable underperformer for the period with a return of -18.8%, languished due to
continued concern over legal battles. We will continue to emphasize investments
in high quality, fundamentally strong businesses as we believe that such
companies provide the best opportunity for long-term growth and preservation of
wealth.

"Dogs" of Wall Street Portfolio (SunAmerica Asset Management Corp.)

  For the six months ended July 31, 1999, the "Dogs" of Wall Street Portfolio
posted a return of 7.5%, outperforming the S&P 500 Index's 4.5%.

  Following a difficult first quarter in which value investing remained a
challenge, the "Dogs" of Wall Street Portfolio enjoyed impressive gains during
the second quarter due to a significant increase in market breadth. As the
global economic recovery continues to unfold, value investing should benefit as
earnings power returns to many undervalued sectors of the market. The "Dogs" of
Wall Street is a proven investment strategy that offers greater diversification
as a risk-management tool and the potential for strong total return through a
combination of capital appreciation and dividend income.

Alliance Growth Portfolio (Alliance Capital Management L.P.)

  The Alliance Growth Portfolio posted a 0.3% return for the six-month period
ended July 31, 1999, slightly lagging the Russell 1000 Growth Index at 1.0%.
Much of the underperformance was due to a change in leadership during the second
quarter from the large capitalization growth stocks (which we typically buy) to
the value or economically sensitive issues which have shown lackluster
performance for several years.

  At the end of July, Alliance Growth had a weighted average P/E of
approximately 35x for 26% projected earnings growth, versus 28x for 6% earnings
growth for the S&P 500. Despite absolute valuation concerns, we believe that the
best relative investment opportunity is to own companies that provide the
strongest relative earnings growth (four times the market's growth rate) for
only a 25% premium to the market's valuation. Accordingly, Alliance Growth is
concentrated in a number of stocks within the technology, consumer services and
financial sectors that exhibit these low P/E-to-growth characteristics. As of
the end of July, the top ten holdings were Dell, Nokia, Tyco, Home Depot, Morgan
Stanley Dean Witter, MCI Worldcom, Schering Plough, Cisco, Intel, and Associates
First Capital.

MFS Growth and Income Portfolio (MFS Investment Management)

  For the six months ended July 31, 1999, the portfolio provided a 2.6% return,
below the S&P 500 Index's 4.5%. The underperformance was largely due to a
relative underweighting in technology and in cyclicals -- companies whose
businesses tend to improve during strong economic cycles.

  Among the portfolio's best-performing sectors has been communications. The
largest positions in this sector are telecommunications companies, including
Bell Atlantic, MCI WorldCom, SBC Communications, and the long-distance telephone
group at Sprint. Sales growth for these companies and for telecommunications
companies in general has been very strong. The Internet has driven demand for
telecommunications services, and both telecommunications equipment and service
companies have performed well as a result.

  Going forward, we will continue to avoid stocks that we feel are the most
expensive in relation to their earnings potential, and will not pursue what we
feel are short-term market trends. We believe this risk-adjusted approach should
provide favorable long-term results.

Putnam Growth Portfolio (Putnam Investments)

  The Putnam Growth Portfolio earned 1.7%, underperforming the S&P 500 Index,
which rose 4.5% for the six months ended July 31, 1999. The portfolio benefited
from an overweighting in conglomerates and from strong stock selection in
utilities, consumer staples, and communication services. Avoiding stocks of
high-priced growth companies experiencing a slowdown in their rate of profit
growth also contributed to results. Underweighting economically sensitive,
value-oriented basic materials, energy, and capital goods stocks detracted from
performance, as did weak performance in the portfolio's healthcare holdings.

  We believe that improving global economic conditions will continue to
encourage investors and that the international markets' profit deceleration has
come to an end. The investment team is taking advantage of current market
conditions to broaden the Putnam Growth Portfolio's holdings while maintaining
its growth bias. We have increased our overweighted exposure in technology and
consumer staples and reduced our weightings in financial services and consumer
cyclicals.

Real Estate Portfolio (Davis Selected Advisers, L.P.)

  The Real Estate Portfolio (+2.8%) edged out its benchmark, the Wilshire
Associates REIT Index (+1.5%). Several strong performers among the portfolio's
top positions helped it achieve this superior performance. Apartment Investment
& Management Company, Premier Parks, and Spieker Properties each posted double-
digit returns for the past six months (Premier Parks returned over 22%). This
indicates that although the broader market for Real Estate Investment Trusts and
operating companies has been out of favor, careful selection of high quality
companies can still offer surprisingly strong performance. Portfolio management
will continue to buy well-managed real estate companies with sensible capital
structures for the portfolio, because of our conviction that such companies will
be among the long-term market leaders for this sector.

Small Company Value Portfolio (First American Asset Management)

  The Small Company Value Portfolio gained 5.5% during the six months ended July
31, 1999, compared to a 6.3% return for the Russell 2000 Index.

  After suffering through a difficult first quarter, small cap value stocks were
the second quarter's market leaders, outperforming all other domestic equity
investment categories. Attractive valuations, strong fundamentals, improved
liquidity and ongoing merger and acquisition activity have led to a rally in
small cap stocks.

  During the last six months the portfolio increased its energy exposure,
anticipating a longer-term uptrend in the group. The portfolio has shifted its
technology exposure to two areas of promise: wireless communications
infrastructure and semiconductor capital equipment. The portfolio's finance
sector exposure is lower than the benchmark's -- appropriate in an environment
of rising interest rates and corporate bond underperformance.

MFS Mid-Cap Growth Portfolio (MFS Investment Management)

  From its April 1, 1999, inception through July 31, 1999, MFS Mid-Cap Growth
Portfolio provided a total return of 10.9% compared to the Russell 2000 Index's
12.4% return for the same period.

  Until early April, a narrow band of approximately 50 large-company stocks beat
the rest of the stock market by a wide margin, partly because investors were
seeking less volatility at a time of global market turmoil. That situation has
changed over the past couple of months. Apparently tired of paying excessively
high prices for a few big companies with relatively slow growth rates, investors
have found more attractive prices in mid-cap and small-company stocks.

  The portfolio's relative performance can be largely attributed to strong stock
selection in the technology, leisure and healthcare sectors. Gemstar, the
portfolio's top leisure holding, contributed significantly to the absolute
return, gaining 73% in the quarter. The security continues to benefit from
healthy growth and is up 127% year-to-date.

                                                           ---------------------
                                        7
<PAGE>   9

Aggressive Growth Portfolio (SunAmerica Asset Management Corp.)

  For the six months ended July 31, 1999, the Aggressive Growth Fund returned
4.3% versus the Russell 2000 Index return of 6.3%. The portfolio's small-cap
positions were direct beneficiaries of the market's broadening, especially
during the spring months. While many of the portfolio's smaller stocks such as
GST Telecommunications, Invitrogen, Mobile Mini and Oshkosh Truck exploded on
the upside, the portfolio's technology investments suffered a correction after
experiencing stellar gains during the first quarter. During this period, we
lowered the portfolio's technology weighting and redeployed the assets to
increase the oil service position. This position significantly outperformed and
helped to offset the volatility suffered in the technology sector.

  With the market close to new highs at the end of July and the continued
overhang of the Fed's recent interest rate hike, management is currently
maintaining a more defensive position with higher cash and reduced exposure to
the more volatile sectors. While the fundamental outlook for the portfolio's
equity positions continues to be robust, we will remain more cautious until
there is a clearer picture of the inflationary direction within the U.S.
economy.

International Growth and Income Portfolio (Putnam Investments)

  For the six months ended July 31, 1999, the International Growth and Income
Portfolio gained 17.0% in U.S. dollars versus 7.4% for the MSCI EAFE Index.
Strong performers included Nikko Securities, a Japanese financial services
company that advanced following dramatic restructuring efforts; Cookson Group, a
British industrial products company that gained more than 75% amid a selloff of
peripheral businesses; SKF, a Swedish bearings company that surged more than 90%
following corporate restructuring; and Elf Acquitaine, a French energy company
that advanced following a hostile takeover bid and strong oil prices.

  The outlook for European markets amid increased economic activity, especially
in the large German and British economies, is encouraging. Equally encouraging
is the fact that European corporations continue to pursue aggressive
consolidation in an effort to obtain greater scale and competitiveness while
also advancing the interests of shareholders.

Global Equities Portfolio (Alliance Capital Management L.P.)

  For the six months ended July 31, 1999, the Global Equities Portfolio (+4.2%)
underperformed the MSCI World Index (+6.0%) by a 1.8% margin. Much of the
underperformance came from regional asset allocation. Stock selection made a
positive contribution, while currency management detracted from relative
performance.

  Asset allocation had a negative effect on returns as a result of the portfolio
being underweighted in Japan and the Asia ex-Japan regions during a period when
these regions significantly outperformed the broad benchmark. Stock selection
made a positive contribution as competitive returns from our holdings in Europe,
Japan, and Asia offset modest weakness in the relative performance of our U.S.
holdings. Weakness in consumer staples and healthcare offset strong gains for
technology and media holdings in the U.S. In the case of the latter two sectors,
we owned several stocks that reported disappointing earnings during the period.
The sharp declines in their share prices and the relative weightings in those
positions were sufficient to offset gains earned elsewhere among our U.S.
holdings.

International Diversified Equities Portfolio (Morgan Stanley Asset Management)

  The International Diversified Equities Portfolio's 5.3% return lagged the MSCI
EAFE Index's 7.4% for the six months ended July 31, 1999. Portfolio performance
was enhanced by overweight allocations in Japan and Singapore, while an
underweighting in Finland and overweighting in Spain detracted from results.

  During the period, the portfolio was overweighted in Japan. Although there
will be ebbs and flows in the news from Japan, restructuring is the core story
and it is occurring. The economy remains fragile, but does appear to be
bottoming. The portfolio was overweighted in Singapore, and management moved to

overweight Hong Kong in August based on the belief that Hong Kong could benefit
from China's expected entry into the World Trade Organization and from an
orderly renminbi devaluation.

Emerging Markets Portfolio (Putnam Investments)

  For the six months ended July 31, 1999, the Emerging Markets Portfolio surged
34.1% in U.S. dollar terms, although it still underperformed the 38.3% return of
the MSCI Emerging Markets Free Index. Stock selection made the largest
contribution to performance, though country allocation also added significant
value. Selection was particularly advantageous in Korea and Mexico. High
exposure in the major markets of Brazil and Mexico, which performed relatively
well, and minimal exposure to smaller, underperforming markets, such as
Indonesia, contributed to returns.

  Following the dramatic rise of emerging markets in 1999, it is probably time
for a pause. We would not be surprised if emerging-markets returns slowed in the
near term, especially amid rising interest rates in the U.S. and Y2K concerns.
Over the long term, however, we remain bullish on emerging-markets stocks.
Economic recovery has taken a firm hold in Asia; Latin America should be the
next region to recover, helped in large part by the rebound in oil and copper
prices. Firm commodity prices should also help South Africa and Russia, while
emerging Europe should benefit from the general improvement in the outlook for
European economic growth.

  This concludes the overview and portfolio summaries for the SunAmerica Series
Trust. We look forward to making our next report to you in six months, and we
appreciate the opportunity to serve your long-term retirement needs.

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. Investments in securities related to gold and other precious
metals and minerals are considered speculative and are impacted by a host of
worldwide economic, financial, and political factors. Mortgage-backed securities
are subject to prepayment, which can result in reinvestment of principal at
lower yields. Money market instruments generally offer stability and income, but
an investment in these securities is not guaranteed by the U.S. government or
any other entity.

SUNAMERICA SERIES TRUST
NOTES TO FINANCIAL STATEMENTS (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. Shares of the Trust are
issued and redeemed only in connection with investments in and payments under
variable annuity contracts and variable life contracts.

  The Trust issues 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 at net asset value without any sales or
redemption charge.

The investment objectives for the portfolios included in this report are as
follows:

by investing in a diversified selection of money market instruments.

The CORPORATE BOND PORTFOLIO seeks high total return with only moderate price
risk by investing primarily in investment grade fixed income securities.

and, to a lesser extent, capital appreciation, by investing in high quality
fixed income securities of U.S. and foreign issuers and transactions in foreign
currencies.

The HIGH-YIELD BOND PORTFOLIO seeks high current income and, secondarily,

The UTILITY PORTFOLIO seeks high current income and moderate capital
appreciation by investing primarily in equity and debt securities of utility
companies.

primarily in common stocks and other equity securities of companies that its
Subadviser believes have above-average growth prospects primarily in emerging

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,
exchange rate 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.

<PAGE>   174

  Realized foreign exchange gains and losses on other assets and liabilities and
change in unrealized foreign exchange gains 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 TO SHAREHOLDERS:  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 are recorded on the ex-dividend date except for certain dividends
from foreign securities, which are recorded as soon as the Trust is informed
after the ex-dividend date. The Trust amortizes premiums and accretes discounts
on fixed income securities, as well as those original issue discounts for which
amortization is required for federal income tax purposes; gains and losses
realized upon the sale of such securities are based on their identified cost.
Portfolios which earn foreign income and capital gains may be subject to foreign
withholding taxes at various rates.

  Common expenses incurred by the Trust are allocated among the Portfolios based
upon relative net assets or other appropriate allocation methods. In all other
respects, expenses are charged to each Portfolio as incurred on a specific
identification basis.

  The Portfolios record dividends and distributions to their shareholders on the
ex-dividend date. The amount of dividends and distributions from net investment
income and net realized capital gains are determined and presented in accordance
with federal income tax regulations, which may differ from generally accepted
accounting principles. These "book/tax" differences are either considered
temporary or permanent in nature. To the extent these differences are permanent
in nature, such amounts are reclassified within the capital accounts based on
their federal tax-basis treatment; temporary differences do not require
reclassification. Dividends and distributions which exceed net investment income
and net realized capital gains for financial reporting purposes but not for tax
purposes are reported as dividends in excess of net investment income or
distributions in excess of net realized capital gains. To the extent
distributions exceed current and accumulated earnings and profits for federal
income tax purposes, they are reported as distributions of paid-in capital. Net
investment income/loss, net realized gain/loss, and net assets are not affected.

  For the period December 1, 1998 through January 31, 1999, the reclassification
arising from book/tax differences resulted in increases (decreases) to the
components of net assets as follows:

  ORGANIZATIONAL EXPENSES:  During the years ended November 30, 1997 and 1998,
$19,122 and $4,717, respectively, were incurred as part of the organization and
registration of additional Portfolios. Such organizational expenses are being
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 ("repo" or
collectively "repos"). 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 July 31, 1999 the Cash Management, High-Yield Bond, SunAmerica Balanced,
"Dogs" of Wall Street and Aggressive Growth Portfolios had a 9.7%, 4.5%, 14.2%,
0.7% and 16.8%, respectively, undivided interest, representing $19,390,000,
$8,960,000, $28,347,000, $1,353,000 and $33,560,000, respectively, in principal
amount, in a joint repo with State Street Bank & Trust Co., which is dated July
30, 1999, bears interest at the rate of 5.00% per annum, has a principal amount
of $200,315,000, and a repurchase price of $200,398,465, matures on August 2,
1999 and is collateralized by $100,000,000 U.S. Treasury Notes (bearing interest
at the rate of 6.13% per annum and maturing July 31, 2000), $25,000,000 U.S.
Treasury Notes (bearing interest at the rate of 6.13% per annum and maturing
December 31, 2001), $25,000,000 U.S. Treasury Notes (bearing interest at the
rate of 6.25% per annum and maturing February 15, 2003), $315,000 U.S. Treasury
Bonds (bearing interest at the rate of 10.38% per annum and maturing November
15, 2009) and $50,000,000 U.S. Treasury Bonds (bearing interest at the rate of
8.13% per annum and maturing August 15, 2019), which together have an
approximate value of $204,344,288.

  In addition, at July 31, 1999, the Cash Management and SunAmerica Balanced
Portfolios had a 22.2% and 24.4%, respectively, undivided interest, representing
$50,000,000 and $55,000,000, respectively, in principal amount in a joint repo
with PaineWebber, Inc., which is dated July 30, 1999, bears interest at the rate
of 5.02% per annum, has a principal amount of $225,000,000, and a repurchase
price of $225,094,125, matures on August 2, 1999 and is collateralized by
$50,000,000 U.S. Treasury Notes (bearing interest at a rate of 5.83% per annum
and maturing November 30, 1999), $13,370,000 U.S. Treasury Notes (bearing
interest at the rate of 5.75% per annum and maturing April 30, 2003),
$50,000,000 U.S. Treasury Notes (bearing interest at the rate of 7.25% per annum
and maturing August 15, 2004), $50,000,000 U.S. Treasury Bonds (bearing interest
at the rate of 7.88% due November 15, 2007) and $47,800,000 U.S. Treasury Bonds
(bearing interest at the rate of 8.00% per annum and maturing November 15,
2001), which together have an approximate value of $233,592,507.

  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.

  At July 31, 1999 the International Diversified Equities Portfolio had
$2,285,977 and $567 in cash and foreign cash, respectively, segregated for open
futures contracts.

  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
- ---------------------
                                       174
<PAGE>   176

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.

  During the period ended July 31, 1999, transactions in written option
contracts were as follows:

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 and repurchase agreements at July 31, 1999, were as

5. MANAGEMENT OF THE TRUST:  SunAmerica Asset Management Corp. ("SAAMCo" or the
"Adviser") 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, 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:
