              DEAR INVESTOR:
 
                We are pleased to present our annual 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.
 
                This report covering the two-month period from December 1, 1998,
              to January 31, 1999, results from a change in the fiscal year-end
              of the trust, which is now January 31. This
              change -- necessitating the issuance of a new annual report -- was
              made in order to reduce trust costs and to facilitate timely
              reporting to our shareholders.
 
                This report also marks the first inclusion of MFS Investment
              Management(R) (MFS) as a manager within the trust. As the first
              mutual fund organization, MFS has investment experience dating
              from 1924 and we are pleased to welcome the firm to the SunAmerica
              Series Trust.
 
                During the period covered in this report, the U.S. stock market
              advanced, with most major market indices reflecting a continuation
              of the positive momentum experienced during the latter part of
              1998. Growth-oriented stocks continued to outperform value-
              oriented stocks and narrow market leadership was held by the
              largest and most highly valued stocks. International equities
              enjoyed robust gains in December, but stalled in January, while
              European bond markets rallied in response to cuts in interest
              rates in a number of countries across the region. A discussion of
              how your investment options performed in this environment is
              included for each Portfolio beginning on page 146.
 
                We appreciate the opportunity to serve your investment needs and
              look forward to reporting to you again in six months.
 
              Sincerely,

              /s/ ELI BROAD

              Eli Broad
              Chairman and Chief Executive Officer
              Anchor National Life Insurance Company

              -----------------------------------------------
 
              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
 
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 separate series of shares ("the Portfolios"), each of which
represents a separate managed portfolio of securities with its own investment
objectives. This report does not include all of the portfolios of the SunAmerica
Series Trust. It includes only those portfolios that are available as part of
the annuity contract in which you have invested. 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 the portfolios included in this report 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 MFS TOTAL RETURN PORTFOLIO (formerly Balanced/Phoenix Investment Counsel
Portfolio) seeks reasonable income, long-term capital growth and conservation of
capital by investing primarily in common stocks and fixed-income securities,
with an emphasis on income-producing securities which appear to have some
potential for capital enhancement.
 
The ASSET ALLOCATION PORTFOLIO seeks high total return (including income and
capital gains) consistent with preservation of capital over the long-term
through a diversified portfolio that can include common stocks and other
securities having common stock characteristics, bonds and other intermediate and
long-term fixed-income securities and money market instruments (debt securities
maturing in one year or less) in any combination.
 
The UTILITY PORTFOLIO seeks high current income and moderate capital
appreciation by investing primarily in the equity and debt securities of utility
companies.
 
The GROWTH-INCOME PORTFOLIO seeks growth of capital and income by investing
primarily in common stocks or securities which demonstrate the potential for
appreciation and/or dividends.
 
The FEDERATED VALUE PORTFOLIO seeks growth of capital and income by investing
primarily in the securities of high quality companies.
 
The VENTURE VALUE PORTFOLIO seeks to achieve growth of capital by investing
primarily in common stocks.
 
The "DOGS" OF WALL STREET PORTFOLIO seeks total return (including capital
appreciation and current income) primarily through the annual selection of
thirty high dividend yielding common stocks from the Dow Jones Industrial
Average and the Standard & Poor's 400 Industrials.
 
The PUTNAM GROWTH and ALLIANCE GROWTH PORTFOLIOS each seeks long-term growth of
capital by investing primarily in common stocks or securities with common stock
characteristics which demonstrate the potential for appreciation.

The MFS GROWTH AND INCOME PORTFOLIO (formerly Growth/Phoenix Investment Counsel
Portfolio) seeks reasonable current income and long term growth of capital and
income by normally investing in equity securities.
 
The GLOBAL EQUITIES PORTFOLIO seeks long-term growth of capital through
investment primarily in common stocks or securities of U.S. and foreign issuers
with common stock characteristics which demonstrate the potential for
appreciation and through transactions in foreign currencies.
 
The INTERNATIONAL GROWTH AND INCOME PORTFOLIO seeks growth of capital and
current income through investment primarily in common stocks and securities
principally traded on markets outside the United States that offer potential for
capital growth and current income.
 
The INTERNATIONAL DIVERSIFIED EQUITIES PORTFOLIO seeks long-term capital
appreciation by investing in accordance with country weightings determined by
the Subadviser in common stocks of foreign issuers which, in the aggregate,
replicate broad country indices.
 
The REAL ESTATE PORTFOLIO seeks total return through a combination of growth and
income by investment primarily in securities of companies principally engaged in
or related to the real estate industry or which own significant real estate
assets or which primarily invest in real estate instruments.
 
The AGGRESSIVE GROWTH PORTFOLIO seeks long-term growth of capital through
investment primarily in equity securities of small capitalization growth
companies.
 
The EMERGING MARKETS PORTFOLIO seeks long-term capital appreciation by investing
in common stocks that have above-average growth prospects primarily in emerging
markets outside the United States.
 
2. SIGNIFICANT ACCOUNTING POLICIES:  The preparation of financial statements in
accordance with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts and disclosures
in the financial statements. Actual results could differ from these estimates.
In the opinion of management of the Trust, the accompanying financial statements
contain all normal and recurring adjustments necessary for the fair presentation
of the financial position of the Trust, 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.
 
  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
                                                           ---------------------
                                       133
<PAGE>   135
 
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 January 31, 1999, the Aggressive Growth, High-Yield Bond, Cash Management,
SunAmerica Balanced and "Dogs" of Wall Street Portfolios had a 16.8%, 11.3%,
5.5%, 12.6% and 1.2%, respectively, undivided interest, representing
$23,693,000, $15,967,000, $7,695,000, $17,738,000 and $1,691,000, respectively,
in principal amount, in a joint repo with State Street Bank & Trust Co., which
is dated January 29, 1999, bears interest at the rate of 4.65% per annum, has a
principal amount of $140,700,000

and a repurchase price of $140,754,521, matures on February 1, 1999, and is
collateralized by $16,055,000 of U.S. Treasury Notes (bearing interest at the
rate of 4.00% per annum and maturing October 31, 2000), $44,990,000 of U.S.
Treasury Bonds (bearing interest at the rate of 6.13% per annum and maturing
November 15, 2027), $65,040,000 of U.S. Treasury Notes (bearing interest at the
rate of 7.50% per annum and maturing February 2, 2005), which together have an
approximate value of $143,525,575.
 
  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 January 31, 1999 the International Diversified Equities Portfolio had
$2,172,750 and $13,854 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 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.
 
4. FEDERAL INCOME TAXES:  The Trust intends to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and
distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal tax provision is
required.
 
  The amounts of aggregate unrealized gain (loss) and the cost of investment
securities for tax purposes, including short-term securities and repurchase
agreements at January 31, 1999, were as follows:

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

SUNAMERICA SERIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE TRUSTEES AND SHAREHOLDERS OF SUNAMERICA SERIES TRUST
 
In our opinion, the accompanying statement of assets and liabilities, including
the investment portfolios, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Cash Management Portfolio, Global
Bond Portfolio, Corporate Bond Portfolio, High-Yield Bond Portfolio, Worldwide
High Income Portfolio, SunAmerica Balanced Portfolio, MFS Total Return Portfolio
(formerly Balanced/Phoenix Investment Counsel Portfolio), Asset Allocation
Portfolio, Utility Portfolio, Growth-Income Portfolio, Federated Value
Portfolio, Venture Value Portfolio, Alliance Growth Portfolio, MFS Growth and

Portfolio, International Diversified Equities Portfolio, Real Estate Portfolio,
Aggressive Growth Portfolio, "Dogs" of Wall Street Portfolio and Emerging
Markets Portfolio (constituting twenty-two portfolios of the SunAmerica Series
Trust, hereafter referred to as the "Fund") at January 31, 1999, and the results
of each of their operations, the changes in each of their net assets and the
financial highlights for each of the periods indicated, in conformity with
generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at January 31, 1999 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.

    COMPARISONS: PORTFOLIOS VS. INDEXES
 
              The following graphs compare the performance of a $10,000
              investment in the presented SunAmerica Series Trust Portfolios
              (with the exception of Cash Management) to a $10,000 investment in
              a securities index since the portfolio inception. Please note that
              variable annuity minimum premiums vary by contract and may be
              higher or lower than the $10,000 depicted. Following each graph is
              a discussion of portfolio performance and factors affecting it
              over the last one-year period.
 
              THESE GRAPHS AND TABLES SHOW THE PERFORMANCE OF THE PORTFOLIOS AT
              THE SUNAMERICA SERIES TRUST LEVEL AND INCLUDE ALL TRUST EXPENSES
              BUT NO INSURANCE COMPANY EXPENSES ASSOCIATED WITH THE VARIABLE
              ANNUITY AND NO CONTINGENT DEFERRED SALES CHARGE. ALL DIVIDENDS ARE
              ASSUMED TO BE REINVESTED. NO EXPENSES ARE DEDUCTED FROM THE
              PERFORMANCE OF THE INDEXES.

              Cash Management Portfolio
 
              The two-month period ended January 31, 1999, showed continued
              strength in the U.S. economy. Nonfarm payrolls rose by 245,000 and
              378,000 during December and January, respectively, while the
              unemployment rate fell to a 29-year low of 4.3%. As expected, due
              to the strength of the economy, the Federal Reserve policymakers
              left the Federal Funds rate unchanged at 4.75%.
 
              The Cash Management Portfolio performed below average during the
              period. This is a reflection of the volatility of net assets over
              the past several months. This volatility has caused us to keep the
              average maturity slightly shorter than the Donaghue average of
              approximately 55 days. The shorter duration led to the
              underperformance.
 
              With the economy continuing to derive substantial support from a
              resilient stock market and rapid monetary growth, the chances of
              the Fed easing anytime soon appear increasingly remote.
              Conversely, the combination of rising productivity and continued
              low inflation should keep the Fed from shifting to a tightening
              bias. We expect the Federal Reserve to hold short-term rates
              steady at 4.75%. We will continue to search for the best relative
              valued securities and will structure the Portfolio to be flexible
              for any changes in our economic outlook.
 
                     Past performance is no guarantee of future results.

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


 
              The Global Bond Portfolio returned 1.53% for the two-month period
              ended January 31, 1999, outperforming its benchmark, the J.P.
              Morgan Global Government Bond Index, which returned 1.01%. Much of
              the Portfolio's performance can be attributed to its focus on
              securities of high credit quality, which were well rewarded by the
              financial markets during the period. Additionally, the recent
              market environment provided a positive backdrop for global bonds,
              as the market focused on interest rate cuts in peripheral European
              markets, global economic weakness, and low inflation.
 
              The Portfolio profited primarily from its positions in Europe as
              the European bond markets rallied in response to interest rate
              cuts in Sweden, Denmark, the U.K., and the eleven European
              Monetary Union (EMU 11) central banks. In December, investment
              professional surveys conducted in France, Germany, and the U.K.
              further indicated falling business confidence in major core
              European economies, pointing to an economic slowdown.
 
              In Europe, we maintain an overweighted position to take advantage
              of ongoing strength in the European bond markets. We have added
              long positions in the Australian, New Zealand, and Norwegian
              markets following an increase in spreads in these countries, and
              we have also added to the Portfolio's exposure to Treasury
              Inflation Protection Securities (TIPS) in the U.S., which we feel
              are undervalued by the market. In Japan, we will continue to
              maintain an underweighted position in light of increased prospects
              for volatility in that country.
 
                     Past performance is no guarantee of future results.

 AVERAGE ANNUAL TOTAL RETURNS AS OF 1/31/99
- -----------------------------------------------------

    1-year                                 5.58%

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

(2)The Lehman Brothers Corporate Bond Index includes all publicly issued, fixed 
rate, nonconvertible investment grade, dollar-denominated, SEC-registered 
corporate debt.

(3)The Lipper Corporate BBB Rated Index is an average of variable annuity 
accounts that include at least 65% of assets in corporate and government debt 
issues in the top four grades.



              For the two-month period ended January 31, 1999, the Corporate
              Bond Portfolio's 1.35% return outperformed the Lehman Brothers
              Aggregate Index return of 1.02%, the Lehman Brothers Corporate
              Bond Index return of 1.28%, and the Lipper Corporate BBB Rated
              Index return of 1.03%.
 
              Interest rate levels did not change significantly during the
              period. Intermediate maturities (two to five years) saw rates rise
              approximately five basis points, while 10-year rates fell seven
              basis points, flattening the yield curve somewhat. Economic
              releases over the two months were certainly stronger than
              expectations, providing support to the fixed income spread
              sectors. Within spread sectors, corporate bonds -- both investment
              grade and high yield -- significantly outperformed comparable
              maturity Treasury securities as yield spreads continued to tighten
              from the excessively wide levels reached in the fall of 1998.
 
              Within the Corporate Bond Portfolio, a gradual composition shift
              has been underway toward a slightly shorter average maturity and a
              higher yielding/lower quality posture. Given sustained economic
              activity in a relatively modest inflation environment, it appears
              that spread sectors may be in a position to continue
              outperforming. For this reason, the high-yield bond position is
              being slightly increased with a slight decrease in duration.
 
                     Past performance is no guarantee of future results.

 HIGH-YIELD BOND PORTFOLIO
 AVERAGE ANNUAL TOTAL RETURNS AS OF 1/31/99
- -----------------------------------------------------

    1-year                                -3.26%
    5-year                                 6.43%

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


 
              There were no major changes in the High-Yield Bond Portfolio over
              the two-month period ended January 31, 1999. The Portfolio's total
              return over the period was 1.46%, outperforming the Merrill Lynch
              High-Yield Master Index return of 1.01%.
 
              Most of this return was achieved in January as the high-yield
              market began the year on a strong note. Several of the Portfolio's
              top ten holdings benefited from major credit-enhancing
              transactions over the period. Microsoft made equity investments in
              both NTL Inc. and United International Holdings during January,
              and Southwestern Bell agreed to acquire Comcast Cellular, which
              moved Comcast's bonds up to investment grade.
 
              The average credit rating of the Portfolio remained steady within
              the B-B1 range, and we expect this to continue throughout 1999. We
              benefited over the period from an underweighted position in energy
              and healthcare as both these sectors drastically underperformed.
              Given the importance of these sectors, we are actively looking to
              add to our positions at attractive valuations.
 
                     Past performance is no guarantee of future results.

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

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

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



              For the two-month period ended January 31, 1999, the Worldwide
              High Income Portfolio returned -1.84%, above the -3.71% return for
              the benchmark, a blend of 50% First Boston High-Yield Index and
              50% J.P. Morgan Emerging Markets Bond Index Plus. The Portfolio's
              performance was adversely affected by an overweighting in emerging
              markets debt versus high-yield debt, but outperformance within the
              two asset classes overcame the adverse effects of the asset
              allocation decision.
 
              Within the emerging markets debt portion of the Portfolio,
              performance was enhanced by an underweighting in Brazilian and
              Venezuelan assets. In addition, overweighted positions in smaller
              countries that require little external financing aided
              performance.
 
              Within the high-yield portion of the Portfolio, performance
              benefited from favorable mergers and acquisitions activity both in
              the U.S. and Europe. Additionally, an overweighted position in the
              telecommunications industry continued to aid performance.
 
              The Portfolio also benefited from being positioned with a shorter
              interest rate duration than the benchmark as U.S. interest rates
              rose over the two-month period.
 
                     Past performance is no guarantee of future results.

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

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

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



              The SunAmerica Balanced Portfolio continued its outperformance
              during the two-month period ended January 31, 1999. For the two
              months, the Portfolio was up 10.44%, well ahead of the blended
              benchmark (55% S&P 500, 35% Lehman Brothers Aggregate Index, and
              10% Treasury bills), which returned 5.99%.
 
              The Portfolio continues to benefit from our investment theme of
              quality and growth. During the period, we increased our exposure
              to select healthcare and technology positions. As we look to the
              remainder of 1999, our strategy is to continue to find companies
              with above-average revenue and earnings growth. Recently we have
              been increasing our weighting in the telecommunications and media
              sectors as we believe these two industries will benefit from
              synergistic opportunities in 1999. We also continue to follow the
              strength of the U.S. consumer -- a strong contributor to the
              economy during the fourth quarter -- and have increased our
              financial weighting in companies with strong earnings from credit
              card exposure.
 
              We continue to believe that we remain in a moderate growth, low
              inflationary environment. A solid economic backdrop, liquidity,
              and moderate corporate earnings growth will continue to be the
              driving force of the market and higher prices are ahead.
              Volatility, however, will continue. The dynamics of this period
              continue to change, but the basic underpinnings of this market
              remain intact.
 
              The top five equity holdings in the Portfolio at the end of the

 MFS TOTAL RETURN PORTFOLIO
 AVERAGE ANNUAL TOTAL RETURNS AS OF 1/31/99
- -----------------------------------------------------

    1-year                                18.61%
    Since Inception (10/28/94)            16.91%

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


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


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


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


              For the two months ended January 31, 1999, the MFS Total Return
              Portfolio gained 5.88% -- a return comparable to the blended
              benchmark (55% S&P 500, 35% Lehman Brothers Aggregate Bond Index,
              and 10% Treasury bills), which advanced 5.99%.
 
              The primary objective of the Portfolio is to seek above-average
              income (compared to a Portfolio invested entirely in equity
              securities) consistent with the prudent employment of capital and
              secondarily to provide reasonable opportunity for growth of
              capital and income.
 
              As was the case in 1998, growth stocks outperformed value stocks
              during the period. We believe, however, that valuations are too
              rich in many of the growth sectors and are patiently awaiting
              value to be recognized in sectors other than technology.
 
              As we look forward to 1999, we will seek to add to our equity
              positions when valuations become more reasonable. We will maintain
              our discipline in an effort to produce consistent returns with low
              volatility.
 
                     Past performance is no guarantee of future results.

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

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

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



              The Asset Allocation Portfolio returned 1.49% during the reporting
              period, underperforming its blended benchmark of the S&P 500 Index
              (60%) and the Lehman Brothers Aggregate Index (40%), which
              returned 6.47%. The Portfolio's underperformance stemmed primarily
              from the equity portion of the Portfolio's value discipline.
 
              Our value discipline has allowed us to exploit market anomalies
              and invest in companies that sell at a substantial discount to the
              market and to their respective industries. However, during the
              two-month reporting period, growth-oriented stocks outperformed
              their value-oriented counterparts, with the S&P 500/BARRA Growth
              Index returning 14.15% -- nearly ten percentage points higher than
              the S&P 500/BARRA Value Index return of 5.48%. We continue to
              believe that when, over the course of a multi-year investment
              horizon, short-term issues are resolved, cycles turn, or corporate
              actions become evident -- and acknowledged by the broader Wall
              Street community -- our value investments will generate solid
              returns for our shareholders.
 
              As of January 31, 1999, the allocation of the Portfolio stood at
              an overweighted position in stocks at 60%, an underweighted
              position in bonds at 30%, and a 10% allocation to cash and cash
              equivalents. The overall allocation of the Portfolio is more
              aggressive than was the allocation at the beginning of the
              reporting period, which stood at 53% for stocks, 32% for bonds and
              15% for cash and cash equivalents.
 
                     Past performance is no guarantee of future results.

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

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



              The stock market rebounded sharply during the two-month period
              ended January 31, 1999, with the S&P 500 returning 10.18%. The
              market environment appeared to become speculative, with a mania
              over Internet stocks -- an environment in which a conservative,
              value-oriented fund like the Utility Portfolio will naturally
              trail. The Portfolio returned 0.76% during the period.
 
              By sector, the S&P Electric Index fell 2.8%, Natural Gas rose
              5.2%, and Communications rose 23.1%. Our current strategy is to
              emphasize 1) companies that generate strong cash flow above their
              capital spending and dividend requirements and 2) stocks with high
              dividend yields. Our favorite sectors are electric and gas
              utilities and Real Estate Investment Trusts (REITs).
 
              Cash flow at electric companies is at record levels, and many
              companies are repurchasing their own stock. Industry deregulation
              is leading to consolidation and takeovers. Natural gas companies
              have irreplaceable assets, with gas demand rising and supply
              constrained. Telecommunications stocks have benefited from surging
              demand for high-margin services (such as voice mail and caller
              identification features) and growth in Internet usage, but we are
              concerned about the sharp run-up in these stocks and their
              historically high valuations.
 
              Among non-utilities, REITs (7% of the Portfolio) seem
              exceptionally attractive. They trailed the S&P 500 return by 45%
              in 1998 and are extremely undervalued.
 
                     Past performance is no guarantee of future results.

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



              The Growth-Income Portfolio posted a 15.06% gain for the two-month
              period ended January 31, 1999, outdistancing the S&P 500's 10.18%
              return.
 
              The outperformance was due to an overweighting in the technology
              sector and to strong stock selection in technology (Dell Computer,
              Microsoft, Cisco Systems), in healthcare (Pfizer, Genzyme), in
              consumer services (Telecommunications TCI, Carnival Corp.), in
              financials (Citigroup, Chase Manhattan, Morgan Stanley Dean
              Witter), and in retail (Kohls).
 
              Sector weightings did not change dramatically during the period,
              with the largest exposures in technology (26.8%), finance (16.6%),
              consumer services (12.1%), and consumer staples (9.0%).
 
              The top ten holdings as of January 31 were:  Microsoft (4.9%),
              General Electric (3.9%), Cisco Systems (2.8%), Intel (2.7%),
              Walmart (2.7%), Dell Computer (2.7%), Citigroup (2.5%), Pfizer
              (2.4%), Bristol Myers Squibb (2.3%), and Bank America (2.2%).

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




              For the two-month period ended January 31, 1999, the Federated
              Value Portfolio provided a total return of 3.49% versus 10.18% for
              the S&P 500 benchmark. The two-month period was narrow in terms of
              market participation as returns were dominated by technology (up
              33%) and communications services (up 23%). The average stock in
              the S&P 500, as measured by the equal-weighted S&P 500, returned
              only 3.65%. Value stocks struggled for the period, as witnessed by
              the Russell 1000 Value Index's 4.23% return.
 
              The Portfolio's performance was negatively impacted by our
              significant underweightings in both technology and communication
              services stocks. The Portfolio was also negatively impacted by our
              overweighted positions in the poorly performing basic materials
              and energy sectors. The top five stocks adding to performance for
              the period were Sun Microsystems, Inc., First Data Corp.,
              Electronic Data Systems Corp., AT&T Corp., and Oxford Health
              Plans, Inc. The bottom five in terms of detracting from
              performance were Toys "R" Us, Philip Morris Cos., Inc.,
              Archer-Daniels-Midland Co., Boeing Co., and Dillards, Inc.
 
              As we begin 1999, the markets are faced with numerous challenges.
              At a P/E ratio nearing 30 times, a price-to-book above eight times
              and a dividend yield of 1.3%, the S&P 500 is in uncharted
              valuation territory for this point in any business cycle. Indeed,
              it appears that speculation has worked its way into the market. In
              this type of environment, we believe that our value
              disciplines -- identifying leading companies which are temporarily
              out of favor and appear inexpensive relative to the market as well
              as to their expected growth -- will provide a more reasonable ride
              as rationality works its way back into the market.
 
                     Past performance is no guarantee of future results.

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



              The Venture Value Portfolio delivered a total return of 5.54% for
              the two months ended January 31, 1999, compared to the S&P 500
              benchmark return of 10.18%, an underperformance reflecting the
              market's bias for growth-oriented stocks during the period.
 
              The market's volatility over the past year has been a test of
              conviction. The conviction is to resist selling great companies,
              and rather to buy more shares, when the markets are in chaos. We
              believe the recent market declines -- however painful -- represent
              opportunities to buy our favorite stocks at much better prices. We
              continue to take advantage of market downturns by upgrading the
              quality of the Portfolio and sticking with large weightings in our
              favorite companies that are selling at well-below-market multiples
              despite their strong prospects for long-term earnings growth.
 
              The major industries in which the Venture Value Portfolio invests
              are financials, technology, and consumer products. Hewlett
              Packard, American Express, Wells Fargo & Company, and McDonald's
              are among the top holdings. We have added to one of the
              Portfolio's top holdings -- American Express -- throughout the
              year, particularly when the stock came under short-term pressure.
              We expect this financial growth company, with a brand recognized
              worldwide, to benefit from the long-term trend of Baby Boomers
              saving for retirement. Although American Express benefits from the
              U.S.
              consumer's propensity to pay with plastic, it makes its money from
              membership fees and transaction charges rather than through risky
              lending.
 
              Hewlett Packard is the largest technology holding in the
              Portfolio. Hewlett Packard allows us to participate in the growth
              of the technology sector through a dominant industry leader that
              has diversified lines of business but does not possess the high
              P/E risk of today's "go-go" growth stocks.
 
                     Past performance is no guarantee of future results.

  "DOGS" OF WALL STREET PORTFOLIO
  AVERAGE ANNUAL TOTAL RETURNS AS OF 1/31/99*

      Since Inception (4/1/98)                       -4.00%

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



              For the two-month period ended January 31, 1999, the "Dogs" of
              Wall Street Portfolio had a total return of -2.14%,
              underperforming the S&P 500 benchmark return of 10.18%. The
              Portfolio's emphasis on value-style stocks -- which were
              outperformed by growth -- accounted for much of the difference.
 
              Value investing continues to be a challenge in the current market
              environment. In fact, at the end of January 1999, the 50 largest
              stocks in the S&P 500 by capitalization had an average multiple of
              29 and accounted for 55% of the total capitalization of the index.
              The remaining 450 had an average multiple of 20 and accounted for
              45% of the index's total capitalization.
 
              We continue to believe that value names are an excellent way to
              invest and that the fundamentals for many of these companies are
              strong and improving. The Portfolio's top holdings as of the end
              of January 1999 were General Motors Corp., Kellogg Co., Cooper
              Tire & Rubber Inc., ALLTEL Corp., and Minnesota Mining &
              Manufacturing Co.
 
                     Past performance is no guarantee of future results.

(1)The Russell 1000 Growth Index consists of stocks with a greater-than-average 
growth orientation. Companies in this index tend to exhibit higher 
price-to-book and price-earnings ratios, lower dividend yields and higher 
forecasted growth values.

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




              For the two months ended January 31, 1999, the Putnam Growth
              Portfolio gained 16.43%, outperforming the S&P 500 Index return of
              10.18%, as well as the Russell 1000 Growth Index return of 15.42%.
              During the period, we witnessed a continuation of the overall
              five-year trend of large-company stocks outperforming
              small-company stocks and growth stocks outperforming value.
 
              During the period, the Portfolio benefited from an overweighting
              in the top-performing technology and consumer cyclical sectors as
              well as from solid stock selection in consumer cyclicals and
              capital goods. It also benefited from an underweighting in the two
              worst performers: energy and basic industrials. While the
              Portfolio outperformed the index for both months, January's
              performance was hindered by an overweighting in the lagging
              healthcare sector and by weak stock selection in healthcare and
              financials.
 
              Looking ahead, the Portfolio remains overweighted in consumer
              stocks (primarily retail) and in selected technology and
              healthcare areas. Sectors in which earnings growth is less evident
              and in which the Portfolio is underweighted include energy, basic
              industry, and utilities. Given the unsettled nature of the global
              economy, the market will likely remain volatile going forward.
              However, low inflation and recent declines in interest rates may
              serve as the foundation for domestic stability, helping to
              maintain investor confidence and nurture growth. In this
              environment, we are maintaining our disciplined approach to stock
              selection, which we believe will result in superior returns over
              time.
 
                     Past performance is no guarantee of future results.

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



              The MFS Growth and Income Portfolio was up 10.47% for the
              two-month period, slightly ahead of the S&P 500's 10.18% return.
 
              The objective of the MFS Growth and Income Portfolio is to seek
              reasonable current income and long-term growth of capital and
              income by normally investing in equity securities. The Portfolio's
              goal is to outperform the S&P 500 by selecting stocks which offer
              above-average, sustainable earnings growth at a reasonable price
              and to achieve market or below-market volatility.
 
              MFS employs an active, research-driven approach to investing in
              large capitalization, "blue chip" U.S. stocks. We believe that our
              research-focused investment discipline has helped us in discerning
              which companies' earnings are intact and growing consistently.
              Looking ahead, we are predicting slower earnings growth for
              domestic equities in 1999, as well as low inflation and low
              interest rates. The environment dictates that we pay close
              attention to earnings consistency and reliability, so we do not
              intend to modify our fundamental method for selecting stocks. Our
              discipline and our research focus have proved to be sound, and we
              believe our approach will continue to work in the future.
 
              As of January 31, 1999, the Portfolio's top sector weightings were
              financial services (17%), healthcare (14%), technology (13%),
              consumer staples (10%) and utilities (9%).
 
                     Past performance is no guarantee of future results.

(1)The Russell 1000 Growth Index consists of stocks with a greater-than-average 
growth orientation. Companies in this index tend to exhibit higher 
price-to-book and price-earnings ratios, lower dividend yields and higher 
forecasted growth values.



              The Alliance Growth Portfolio outperformed the Russell 1000 Growth
              Index during the two-month period ended January 31, 1999, with a
              25.75% return versus the benchmark's return of 15.42%. The
              outperformance was due both to overweightings in the technology
              and retail sectors and to strong stock selection. America Online,
              Tyco International, MBNA, HBO & Company, Pfizer, Dayton Hudson,
              Dell Computer, Nokia, Cisco Systems, EMC Corp., and Airtouch all
              significantly outperformed.
 
              Sector allocations did not change dramatically during the period.
              The largest sector exposures at the period's end continued to be
              technology (42.8%), consumer services (16.5%), finance (15.4%),
              and healthcare (14.0%). The top ten positions at January 30, 1999,
              were Nokia (6.8%), Dell Computer(6.3%), Airtouch (6.3%), Home
              Depot (4.9%), Cisco Systems (4.7%), Tyco International (4.6%),
              Intel (4.4%), EMC Corp. (3.8%), MBNA (3.5%), and Pfizer(3.2%).

(1)The MSCI World Index is one of the Morgan Stanley Capital International 
indexes and measures stock market performance in the U.S., Europe, Canada, 
Australia, New Zealand, the Far East and emerging markets.



              The rally in global equities continued into the 1998 year-end and
              start of 1999. For the two-month period ended January 31, 1999,
              global equities, as measured by the MSCI World Index (with net
              dividends reinvested), rose 7.21% in U.S. dollar-terms. The return
              of the Global Equities Portfolio during the same period was
              10.12%. The Portfolio's superior return was the result of strong
              performance by key technology and financial holdings, and an
              underweighted exposure to Japan, which continued to lag the
              recovery in global equities.
 
              Nothing has happened to change our view that markets are generally
              full value and subject to ongoing shocks in terms of corporate
              earnings, news announcements, and potential economic disruptions
              emanating from emerging markets. As expected, volatility has been
              more two-way this year, with markets moving up and down in almost
              equal measure every two days or so. The intense sensitivity
              investors continue to exhibit to pieces of news suggests that any
              stock at any given point in time could rise or fall 20% in value
              on just the smallest rumor or change in expectations. As such, our
              focus on buying and selling stocks remains highly price sensitive.
 
              Regional exposures within the Portfolio have changed little.
              Assets are now distributed much closer to benchmark levels than
              last year as we see little to differentiate between opportunities
              around the world. Despite sustained domestic growth in the U.S.,
              high valuations and apparent economic imbalances leave us cautious
              on the direction of the market even though many businesses in
              which we continue to invest still show "best-in-class" returns.
              Japan offers long-term value but restructuring and policy
              adjustments are needed. Asia looks intriguing on a medium-term
              view and, with prices pulling back somewhat, we have become more
              interested in increasing our exposure. We are focusing on
              Singapore and Australia at the present time.
 
              Europe looks set to have divergent experiences, with Continental
              markets exhibiting weakness near-term and U.K. stocks offering
              tremendous value on domestically geared stocks that should respond
              to the Bank of England's more aggressive easing plans.
 
                     Past performance is no guarantee of future results.

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



              The International Growth and Income Portfolio increased 3.56% for
              the two-month period ended January 31, 1999, on par with the
              Morgan Stanley EAFE Index, which gained 3.68%. International
              equities enjoyed robust gains in December, continuing the powerful
              rally that began in late September. However, the strong recovery
              paused in January as MSCI EAFE slipped 0.30% in U.S. dollar terms.
 
              As we have done for some time, we concentrated on European
              equities and underweighted Asian markets. Many of the Portfolio's
              top performers were found in Continental Europe including the
              French-based STMicroelectronics (up 64%), whose two key
              markets -- hand-held telephones and specialty electronic
              devices -- were particularly strong amid an overall upswing in the
              technology sector. Another impressive performer was Deutsche
              Telecom (up 60%), which shifted strategy and aggressively cut
              prices to maintain market share in both fixed and mobile telephone
              markets. The company also benefited from the improved regulatory
              environment created by the new German government. Another French
              company enjoying big gains was Vivendi (up 31%), a water
              utilities/cellular telephone operator/media conglomerate, which
              continues to improve market share among its core businesses while
              divesting itself of non-core operations.
 
              Looking forward, we continue to upgrade the overall quality of the
              Portfolio to minimize volatility. For example, we added to a
              position in Diageo as its management reorganizes the company's
              product line to optimize profitability and cash flow. At the same
              time, we believe the company's stock is trading at a substantial
              discount to its food and beverage peers.
 
                     Past performance is no guarantee of future results.

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




              For the two-month period, the International Diversified Equities
              Portfolio lagged the MSCI EAFE Index by a 1.63% to 3.69% margin.
              During this period, country allocation decisions to overweight
              Italy, Portugal, and Spain and our underweighted allocation to the
              Netherlands enhanced returns. Our underweighted allocations to the
              smaller European markets of Finland and Belgium and overweighted
              positions in Hong Kong and Singapore detracted from results.
 
              In Japan, we moved from an underweighted allocation -- roughly 75%
              of the benchmark weight -- to neutral in January. This more
              positive outlook on Japan is based on the increasing likelihood of
              a tax cut, meaningful progress on cleaning up the bank sector, and
              signs that the economy is starting to bottom out. Importantly,
              stocks are attractively valued, particularly on a relative basis.
 
              Asia looks relatively attractive as the region has already
              experienced a severe recession, deflation, and a secular bear
              market. Although we cannot identify the beginnings of an economic
              recovery, currencies have strengthened, interest rates have
              fallen, and corporate cost cutting is accelerating.
 
              By contrast, Europe is just beginning to be affected by the
              deflationary malaise. European economies are showing signs of
              slowing as 1999 GDP growth estimates have fallen from over 3% to
              1.5%, export growth is collapsing, and price indexes are falling.
              Analysts' expectations for 1999 earnings in Europe are still 15%.
              We at Morgan Stanley, however, are less optimistic and believe
              there is a good chance corporate earnings in Europe could be flat
              to down this year.
 
                     Past performance is no guarantee of future results.

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



              The Real Estate Portfolio delivered a total return of -2.73% for
              the two-month period from December 1, 1998, to January 30, 1999,
              outperforming the Morgan Stanley REIT Index return of -4.42%.
 
              Although 1998 was a tough year for REITs, they are now offering
              some of the best fundamentals of any publicly traded company and
              are selling at recession-like multiples. Looking at the real
              estate holdings in the Portfolio, we see businesses that are
              currently growing their earnings about twice as fast as the S&P
              500 yet are trading at multiples that are 70% or more lower than
              the multiple on the S&P 500. Earnings growth for real estate
              companies will have to slow from the exceptionally high levels of
              recent years. However, we still anticipate annual earnings
              increases of 6% to 8% and dividend yields of 6%, producing a total
              return of approximately 12%, assuming multiples remain constant.
 
              We believe all the evidence indicates real estate is attractively
              undervalued. We are extremely comfortable with adding to our
              holdings of well-run companies that are capable of generating
              steadily increasing rental income and solid returns on capital. We
              think quality companies such as Vornado Realty Trust, Home
              Properties NY Inc., and Boardwalk Equities Inc., which are among
              the top holdings in the Portfolio, will ultimately be accorded
              premium valuations in the market as other investors recognize
              their true worth.
 
                     Past performance is no guarantee of future results.

(1)The Russell 2000 Index is comprised of the smallest 2000 companies in the 
Russell 3000 Index, representing approximately 11% of the Russell 3000 total 
market capitalization. The Index was developed with a base of $135.00 as of 
December 31, 1986.



 
              For the two-month period ended January 31, 1999, the Aggressive
              Growth Portfolio returned 25.97% versus the Russell 2000 Index
              return of 7.61%.
 
              During the months of December 1998 and January 1999, the Portfolio
              continued its outperformance and recovery off the lows reached
              during the fourth quarter of 1998. Our core sectors of investment
              continue to include the technology and telecommunications groups,
              consumer cyclicals, and the "new media" companies of the Internet.
              While many of our companies within these industries continue to
              report double-digit earnings increases, we initiated partial
              selling recently in the Portfolio's top holdings. Some of these
              partial sell candidates included America Online, Yahoo!,
              Abercrombie & Fitch, Real Networks, CMG Information, and Travel
              Services, as stock price targets have been met and the potential
              for volatility increases.
 
              While we continue to remain optimistic about the market and
              emerging stock performance during 1999, we also are poised for any
              changes in interest rates and the economy which could stall the
              market's tremendous progress since last October.

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



              For the two months ended January 31, 1999, the Emerging Markets
              Portfolio gained 0.20% versus the MSCI Emerging Markets Free
              Index, which posted a return of -3.04%.
 
              Emerging market performance was restrained during the period amid
              devaluation of the Brazilian real, which fell by almost 70%
              against the U.S. dollar. The troubles with the Brazilian currency
              brought an end to the strong emerging market rally in October and
              November of 1998, yet the fallout was not unduly harsh. Chile and
              Mexico, for example, slipped just 2.4% and 1.3%, respectively, in
              January. Meanwhile, emerging markets in Europe rallied, benefiting
              from the successful introduction of the euro in the developed
              markets.
 
              The Portfolio benefited from a large overweighting in Greek banks,
              heavy exposure to electronic stocks in Taiwan, and holdings in
              South Korea. However, performance was hampered by poor stock
              selection in India, South Africa, and Brazil.
 
              Looking ahead, the Latin American markets have endured the
              long-feared Brazilian devaluation and may now be poised to
              rebound. In Asia, we see significant economic restructuring and
              gradually reviving economic growth. Expectations in Europe remain
              positive amid the apparent success of the euro.
 
                     Past performance is no guarantee of future results.

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:
