Annual Report

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--AMERICAN BALANCED FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  For the year ended December 31, 1999, the Fund's Class A Shares had a total
return of +8.73%. This compares to the +21.04% total return for the Standard &
Poor's 500 Index for the same 12-month period.

  As was the case in 1998, the US equity sector had a positive impact on Fund
returns during the fiscal year ended December 31, 1999. The stock market again
was characterized by the significant outperformance of a narrow group of
equities, specifically the shares of technology companies. The Fund benefited
because we had allocated the largest portion of its equity assets to the
technology sector during the year. However, the Fund's return was held down by
the negative overall return produced by US fixed-income securities for the year
as a whole.

PORTFOLIO MATTERS

  As of December 31, 1999, the Fund's asset allocation was: US stocks, 55% of
net assets; US bonds, 39%; and cash reserves, 6%.

  We increased the Fund's US equity representation slightly from 52% of net
assets to 55% during the six months ended December 31, 1999. Technology remained
the largest single group represented in the portfolio, accounting for nearly
one-third of the Fund's US equity assets. This commitment reflects our
continuing emphasis on the shares of companies where we believe a consistent and
above-average rate of earnings growth will be extended over the next several
years and where valuations appear reasonable relative to earnings growth
potential. Consistent with this focus are the Fund's significant commitments in
consumer staples, communication services, financials and health care.

  We reduced the Fund's commitment to US bonds from 44% of net assets to 39%
during the six months ended December 31, 1999. Late in 1999, we took advantage
of an interest rate rise to extend the Fund's average duration to 6.7 years,
after reducing the duration earlier in the second half of 1999. In our opinion,
the Federal Reserve Board is likely to tighten monetary policy in 2000 until the
US economy slows down. Such a slowdown will ease fears of a resurgence of
inflation and enable intermediate-term--long-term US interest rates to decline,
in our view.

IN CONCLUSION

  We appreciate your investment in American Balanced Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to sharing our investment
outlook and strategies with you in our next report to shareholders.

Sincerely,

/s/ Terry K. Glenn

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--AMERICAN BALANCED FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. American Balanced Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Short-term securities are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Directors of
the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity and debt markets. Losses may arise due to
changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Options--The Fund may write covered call options. When the Fund writes an
option, an amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option written. When
a security is purchased or sold through an exercise of an option, the related
premium paid (or received) is added to (or deducted from) the basis of the
security acquired or deducted from (or added to) the proceeds of the security
sold. When an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the premiums
received or paid (or gain or loss to the extent the cost of the closing
transaction exceeds the premium paid or received).

  Written options are non-income producing investments.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends, and
capital gains at various rates.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (e) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

  (f) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $5,764 have been reclassified between undistributed net
realized capital gains and undistributed net investment income. These
reclassifications have no effect on net assets or net asset value per share.

DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  Basic Value Focus Fund enjoyed a particularly good year in terms of
performance, especially in light of the continued challenging environment for
value investing. During the fiscal year ended December 31, 1999, the Fund's
Class A and Class B Shares had total returns of +21.12% and +20.97%,
respectively, matching the total return of 21.04% for the unmanaged Standard &
Poor's 500 Index. The Fund outperformed the average total return of +14.79% of
the Lipper Variable Annuity Growth and Income group for the same period. We
achieved this performance as a result of a substantial positive impact from our
holdings in select technology stocks. For example, Integrated Device Technology,
Inc., a leading semiconductor communication maker, posted a 383% stock price
gain in 1999. Motorola, Inc.'s stock advanced 141% in response to the boom in
sales of wireless handsets. Our longstanding Novell, Inc. holding appreciated
117% following the company's continued turnaround. Our ownership of
Hewlett-Packard Company, International Business Machines Corporation and 3Com
Corporation also aided performance.

  Financials, including both banks and insurance companies, were poor performers
as a result of rising interest rates and company-specific earning shortfalls. We
carried an underweight position in the group for most of the year, but began to
significantly add to our holdings in the fourth quarter. We believe the stage is
set for accelerated bank and insurance company consolidation in 2000 following
recent Government deregulation and the expiration of pooling accounting on
December 31, 2000. Positions in financials that we either added to or initiated
during the period included Bank One Corporation, First Union Corporation, Ace
Limited, The Allstate Corporation, Mellon Financial Corporation, UnumProvident
Corporation, The CIT Group, Inc., Associates First Capital Corporation and The
St. Paul Companies Inc. All of these companies were trading at attractive
valuations, and we expect a more favorable environment for financials in 2000.
Other new positions included Crown Cork & Seal Company, Inc., Sara Lee
Corporation, Columbia/HCA Healthcare Corporation, Burlington Resources Inc.,
Sunoco, Inc., Unisys Corporation, SBC Communications Inc., American National
Insurance Company, Becton, Dickinson and Company and American Home Products
Corporation. In addition, we bought and sold United Parcel Services Inc. and
Agilent Technologies Inc. during the period.

IN CONCLUSION

  Thank you for your investment in Basic Value Focus Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to serving your investment
needs in the months and years ahead.

Sincerely,

/s/ Terry K. Glenn

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--BASIC VALUE FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Basic Value Focus Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-the-counter
market, valuation is the last asked price. Short-term securities are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Directors of
the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity and debt markets. Losses may arise due to
changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Options--The Fund may write covered call options. When the Fund writes an
option, an amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option written. When
a security is purchased or sold through an exercise of an option, the related
premium received is added to (or deducted from) the basis of the security
acquired or deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums received (or
gain or loss to the extent the cost of the closing transaction exceeds the
premium received).

  Written options are non-income producing investments.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (e) Dividends and distributions to shareholders--Dividends and distributions
paid by the Fund are recorded on the ex-dividend dates.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which

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

Company has also entered into a Distribution Agreement and Distribution Plan
with Merrill Lynch Funds Distributor ("MLFD" or the "Distributor"), a division
of Princeton Funds Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary
of Merrill Lynch Group, Inc.
  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of .60% of the average daily value of the Fund's net assets.

  Pursuant to the Distribution Plan adopted by the Company, pursuant to Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor an
ongoing distribution fee each month at the annual rate of .15% of the average
daily value of the Fund's Class B net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a subsidiary of ML & Co., earned $99,074 in commissions on the
execution of portfolio security transactions.
  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Accounting services are provided to the Fund by MLAM at cost.
  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--CAPITAL FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  The fiscal year ended December 31, 1999 proved to be a challenging one for
Capital Focus Fund. While each individual asset class within the Fund performed
respectably against its benchmark, the value style of investing that we espouse
significantly underperformed the growth style of investing as positive equity
performance remained heavily concentrated in the large-capitalization technology
sector of the market. Outside the technology sector, the broader equity market
struggled. The unmanaged Russell 1000 Value Index rose a mere 7.3% in 1999,
while the unmanaged Russell 1000 Growth Index recorded a +33.2% return and the
technology-laden National Association of Securities Dealers Automated Quotations
Composite Index (NASDAQ) appreciated over 85%. Excluding technology, the average
stock in the Standard & Poor's 500 (S&P 500) Index gained just 2% for the year.
Furthermore, the average stock on the New York Stock Exchange and NASDAQ fell
24% from its 52-week high. While we admire many of these leading technology
companies whose stocks performed so handsomely in 1999, the dauntingly high
valuation levels they commanded in the marketplace largely precluded us from
owning them in the Capital Focus Fund and consequently impaired our relative
performance results for the year. Within the fixed-income portion of the
portfolio, the relatively short average duration we maintained proved
beneficial, as intermediate-term domestic interest rates rose throughout the
year.

MARKET REVIEW

  The performance of the US financial markets during the last half of the
six-month period ended December 31, 1999 continued to be dictated by investors'
changing perceptions about the pace of economic growth, the future rate of
inflation and the associated course of action by the Federal Reserve Board. In
early fall, the US equity market continued its summer-long decline as a
weakening of the US dollar against the Japanese yen, a significant widening of
both the trade and current account deficits and a number of high profile
earnings disappointments kept stock prices under pressure. The weak dollar
prompted concerns over threats to Japan's fragile economic recovery and the
potential for accelerated repatriation of US investments. The bulging trade
deficit coupled with rising commodity prices and still robust US economic
activity suggested the Federal Reserve Board could increase short-term interest
rates for the third time this year. Finally, announced earnings shortfalls for
many prominent companies, particularly in the consumer arena, raised concerns
over the sustainability of corporate earnings growth. However, by late fall
evidence of a slowdown in the interest rate-sensitive housing sector, coupled
with declines in durable goods orders and moderate labor cost growth, suggested
inflation remained well-contained and the Federal Reserve Board was unlikely to
increase interest rates again, driving the stock market to a solid advance.
Stocks provided a strong finish to a strong year with a powerful rally in
November and December, driven by a select group of large-capitalization
technology companies whose share prices continued to benefit from expectations
of rapid growth, a cessation of Year 2000-related concerns and the impact of
momentum-driven investors.

  While many market indexes approached or exceeded new highs at the end of
December, the broader equity market continued to struggle. Resuscitated global
economies and a doubling in oil prices precipitated inflationary fears and drove
bond yields higher. In addition, the Federal Reserve Board gave clear indication
of its intent to further increase interest rates to moderate economic growth.
Rising interest rates typically compress stock valuations, creating a difficult
condition for the average equity. In addition, the value style of investing
continued to dramatically underperform the growth style of investing. For the
December quarter, the S&P 500 Index generated a +14.88% total return. The US
bond market continued to struggle between the positive implications of
consistently benign inflationary measures and the perceived negative implication
of continued rapid economic growth. Despite record oil price increases and
employment levels, the US gross domestic product deflator did not even muster a
1.5% gain. Investors continued to believe strong economic growth would prove
inflationary, and bid the yield on long-term Treasury bonds to a 27-month high.
As a result, for the six-month period the unmanaged Merrill Lynch Domestic Bond
Master Index recorded a +0.55% total return. The Fund's Class A Shares generated
a total return of -1.92% for the six months ended December 31, 1999.

PORTFOLIO MATTERS

  We continued to maintain a conservative asset allocation posture within the
Fund, with 60.2% of net assets invested in equities, 32.9% in fixed-income
securities and 6.9% in cash equivalents

                                       28

at December 31, 1999. This reflected our view that the strong performance of
many stock market indexes masks a significant deterioration in underlying
fundamental trends, which is likely to impair the market's ability to sustain
this recent advance. Many of the factors that have propelled the market higher
over the past several years have begun to abate. For example, interest rates,
commodity prices and the Japanese yen have all risen, the liquidity condition
has deteriorated, and non-US markets offer attractive investment alternatives.
Meanwhile, valuations remain near record high levels. This combination of
deteriorating fundamentals and high valuations does not represent a formula for
further significant advances in share prices, in our view. We continued to take
advantage of the significant volatility in many individual stocks and industry
groups to enhance the return potential of the equity portfolio. Meanwhile, bonds
continued to represent good value with inflation adjusted interest rates at
historically high levels and inflationary pressures remaining moderate.

  Within the equity component of the Fund, during the six-month period we
continued to adjust our holdings to seek to enhance quality and limit any risk.
We added six new investments, increased positions in 11 holdings, reduced
positions in 13 holdings and eliminated six stocks from the portfolio. Notable
among the new positions was Alcatel, a global manufacturer of telecommunications
equipment, which enjoys strong market shares in some of this industry's fastest
growth segments. Alcatel sells at a discount to its peers on virtually all
valuation measures. While this has been justified in the past by the company's
inconsistent financial performance, we believe this valuation disparity is
likely to narrow going forward as revenue growth accelerates and margins
improve, driven by business divestitures and cost reduction measures. With the
global telecommunications equipment market expected to grow at a double digit
pace over the next three years, driven by deregulation and rapid growth in data
demand and Internet usage, Alcatel now possesses the means to participate in
this advance. We also established a position in E.I. du Pont de Nemours and
Company, the global chemical and life sciences company, which maintains a
powerful portfolio of high-quality, high-market share proprietary products and
businesses. The company enjoys significant earnings leverage to rising global
economic activity in its cyclical businesses in addition to an accelerating
earnings and productivity program, which should begin to show tangible bottom
line benefits in 2000. In our view, the company's financial condition is sound,
subsequent to the divestiture of its energy business. The company generates free
cash flow and is repurchasing its own stock. Selling at less than 20 times year
2000 estimated earnings per share, yielding 2.5%, down 20% from its recent stock
price high with improving fundamentals and enhanced earnings quality, we believe
DuPont represents excellent value and is an attractive addition to the
portfolio.

  We sold our position in Federal Mogul Corporation, the auto parts concern. The
original investment thesis on Federal Mogul anticipated significant value
creation from the company's strategy of acquiring other auto parts companies in
order to provide complete engine systems to auto manufacturers. Enhanced revenue
growth opportunities and significant cost reduction benefits from the
implementation of this strategy were expected to produce above-average earnings
growth and significant free cash flow. Unfortunately, intense pricing pressures
from the company's customer base and continued weakness in the important auto
after market resulted in stagnant revenues and earnings disappointments. While
the stock remains inexpensively valued, we believe this lack of top line growth
will impair the company's ability to improve shareholder returns. We decided to
eliminate our position in the stock. We also sold our position in General
Electric Company, the diversified conglomerate. After a greater-than 40% advance
in 1999, we viewed the company's shares as fairly valued at a multiple of about
40 times estimated earnings per share. We believe the company's superior
business and financial strengths are more than adequately reflected in this
valuation level, so we decided to eliminate the position.

  Within the fixed-income portion of the portfolio, the relatively short
duration of our bonds continued to produce performance benefits as domestic
interest rates rose sharply during the period. We were also rewarded with a
substantial premium tender offer for one our holdings. We maintained the average
quality rating of our bonds at A2/A as rated by the major rating agencies. We
increased our position in investment-grade corporate bonds from 61.6% of
fixed-income assets at September 30, 1999 to 63.3% while we increased our US
Treasury position from 26.8% of fixed-income assets to 28.2%. High-yield
corporate bonds were unchanged at 8.5% of fixed-income assets. The average yield
to maturity of our bonds at December 31, 1999 was 7.57%, virtually unchanged
from September 30, 1999. Going forward, we anticipate further extending the
average maturity of our bonds from the current 5.4 years to take advantage of
the recent rise in interest rates.

  Capital Focus Fund invests in quality companies whose stocks are undervalued
in the view of Fund management. On average, the stocks in the Fund have
generated comparable returns on shareholder equity and have stronger balance
sheets while offering faster earnings growth than the average company as
measured by the S&P 500 Index. However, these same stocks sell at an average
price/earnings ratio of 20.8 times estimated year 2000 earnings per share as
compared to 29.7 times for the S&P 500 Index, at 5 times current book value per
share as compared to 7.2 times for the S&P 500 Index, and provide a 1.4%
dividend yield as compared to 1.1% for the S&P 500 Index.

IN CONCLUSION

  We appreciate your investment in Capital Focus Fund of Merrill Lynch Variable
Series Funds, Inc., and we look forward to sharing our investment outlook and
strategies with you in our next report to shareholders.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--CAPITAL FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company
("MLLIC"), ML Life Insurance Company of New York (indirect wholly-owned
subsidiaries of Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance
companies that are not affiliated with ML & Co., for their separate accounts to
fund benefits under certain variable annuity and variable life insurance
contracts. Class A and Class B Shares have equal voting, dividend, liquidation
and other rights, except that only shares of the respective classes are entitled
to vote on matters concerning only that class and Class B Shares bear certain
expenses related to the distribution of such shares. Capital Focus Fund (the
"Fund") is classified as "diversified," as defined in the Investment Company Act
of 1940. The Fund's financial statements are prepared in accordance with
generally accepted accounting principles, which may require the use of
management accruals and estimates. The following is a summary of significant
accounting policies followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written are valued at the last sale price in the case of
exchange-traded options or, in the case of options traded in the
over-the-counter market, the last asked price. Short-term securities are valued
at amortized cost, which approximates market value. Futures contracts are valued
at the settlement price at the close of the applicable exchange. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Options--The Fund may write covered call options. When the Fund writes an
option, an amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option written. When
a security is purchased or sold through an exercise of an option, the related
premium paid or received is added to (or deducted from) the basis of the
security acquired or deducted from (or added to) the proceeds of the security
sold. When an option expires (or the Fund enters into a closing transaction),
the Fund realizes a gain or loss on the option to the extent of the premiums
received (or gain or loss to the extent the cost of the closing transaction
exceeds the premium received).

  Written options are non-income producing investments.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a

                                       39
<PAGE>   41
- --------------------------------------------------------------------------------

withholding tax may be imposed on interest, dividends and capital gains at
various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Deferred organization expenses--Deferred organization expenses are charged
to expense on a straight-line basis over a period not exceeding five years.

  (g) Dividends and distributions to shareholders--Dividends and distributions
paid by the Fund are recorded on the ex-dividend dates. Distributions in excess
of investment income are due primarily to differing tax treatments for foreign
currency transactions.

  (h) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $2,549 have been reclassified between undistributed net
realized capital gains and accumulated distributions in excess of net investment
income. These reclassifications have no effect on net assets or net asset value
per share.

2. INVESTMENT ADVISORY AGREEMENT AND
TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of .60% of the average daily value of the Fund's net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("MLPF&S"), a subsidiary of ML & Co., earned $1,920 in commissions
on the execution of portfolio security transactions.

  During the year ended December 31, 1999, Merrill Lynch Security Pricing
Service, an affiliate of MLPF&S, earned $1,010 for providing security price
quotations to compute the Fund's net asset value.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.

  Accounting services are provided to the Fund by MLAM at cost.

  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

3. INVESTMENTS:

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--DEVELOPING CAPITAL MARKETS FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  During the 12-month period ended December 31, 1999, total returns for Merrill
Lynch Developing Capital Markets Focus Fund, Inc.'s Class A and Class B Shares
were +65.52% and +65.38%, respectively. The unmanaged Morgan Stanley Capital
International Emerging Markets Free (MSCI EMF) Index rose 66.41% during the same
period. There were several positive influences on performance during the fiscal
year ended December 31, 1999. Prominent among these was the Fund's large
weighting in South Korea (14.02% of net assets on average) during the year, and
the strong performance of our stock holdings in that market. Likewise, our
weighting of 11.85% of net assets on average in Mexico and the outperformance of
our holdings in that market were beneficial to performance. On the other hand,
the Fund's small position (0.73% of net assets on average) in the Russian market
was somewhat detrimental because it limited our participation in this market's
strong recovery. The Russian market rose 247.06% during the period as measured
by that country's component in the MSCI EMF Index.

INVESTMENT OVERVIEW

  Emerging stock markets rose 66.41% in 1999. This increase more than reversed
two years of declines in these markets. We believe this rally was based on
fundamental factors, and we believe it can continue. These factors include: the
strength of US demand for goods, an upturn in the commodity cycle, the recovery
of several of the countries that were in crisis, the improved perception of risk
in emerging markets, and a revaluation of the companies involved in technology
and Internet-related businesses.

  A factor that was an important impetus early in 1999 was the growth policy
bias in the world's major economies. Most notably, the monetary policy of the US
Federal Reserve Board was relatively easy and US demand was strong. This
reflationary bias was also pervasive in Europe and in Japan. Prices of some
commodities recovered and this was beneficial to producers and exporters. This
recovery supported portfolio holdings such as Companhia Vale do Rio Doce in
Brazil and Impala Platinum Holdings Limited in South Africa. The strength of US
demand for electronics goods benefited semiconductor makers such as Samsung
Electronics, the largest holding in our portfolio, and Taiwan Semiconductor
Manufacturing Company, an integrated circuit foundry.

  A clear beneficiary of reflation has been Mexico because of its trading
relationship with the United States and its exports of oil. Mexican economic
growth projections were raised throughout 1999, supported by a recovery in
indicators such as industrial production, exports and retail sales. As these
came through, corporate earnings estimates were revised upward as well.

  An example of a company whose earnings outlook has improved is Tubos de Acero
de Mexico SA (Tamsa), a Mexican seamless pipe producer. We believe it may
benefit from the cycle upswing of two commodities: oil and steel. For most of
1999, the stock had languished at all-time lows given the poor outlook for both
of these sectors. However, the recent surge in oil prices has prompted oil
companies to expand their rig drilling projects for 2000. This bodes well for
Tamsa as it dominates the deep well pipe market. We also like the fact that each
of a few producers affects the market in the seamless pipe industry, but does
not control it. This prevented the huge price declines witnessed earlier in 1999
for other more commodity-like steels. Tamsa is a subsidiary of the Italian DST
group, which controls more than 30% of the global market and therefore enjoys a
certain amount of price protection. Tamsa stock has begun to move given the
turnaround in sentiment, and we expect more positive news on the company in 2000
earnings.

  During the period, another driving factor was evidence that the economies in
Asia were recovering and that critical reforms were being undertaken to prevent
a recurrence of the crises. The greatest progress in recovery was made by South
Korea at the same time that its banking sector is undergoing reforms.
Furthermore, important companies throughout the region were restructuring by
disposing of non-core assets. The Siam Cement Public Company Limited, one of our
holdings in Thailand, is an example.

  At the same time, the perception of risk by international investors in the
emerging markets improved. This was evident in the successful issuances of
securities by entities from Brazil, Malaysia, South Korea and Thailand in
foreign markets. This allowed interest rates and the cost of capital to decline
and stocks to rally.

  Finally, a unique factor in 1999 was the positive reassessment and revaluation
by investors of the telecommunications and technology companies in emerging
markets. The stocks of companies in related businesses -- including
                                       43
<PAGE>   45
- --------------------------------------------------------------------------------

Internet service providers, software developers and cellular phone
operators--rallied strongly in 1999. Nearly every initial public offering in
this area was extremely successful. We expect the revaluation of these companies
to sustain their rallies, and we have positioned our Fund to participate in
several of them, including Videsh Sanchar Nigam Ltd. (VSNL).

  VSNL is an Indian company whose core business is to provide international long
distance services. The company's monopoly position enables it to dominate access
to the Internet and to sell international bandwidth to Internet service
providers. The potential for VSNL to develop its Internet businesses is
extremely attractive to us, but its basic telephony business is compelling on
its own as it upgrades its network and as the Indian telephone traffic volume
expands. Furthermore, its valuation implies that is it one of the least
expensive telecommunications companies in the world.

IN CONCLUSION

  We thank you for your ongoing interest in Developing Capital Markets Focus
Fund of Merrill Lynch Variable Series Funds, Inc., and we look forward to
reviewing our strategy with you in our next report to shareholders.

Sincerely,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--DEVELOPING CAPITAL MARKETS FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies, that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Developing Capital Markets Focus Fund (the
"Fund") is classified as "non-diversified," as defined in the Investment Company
Act of 1940. The Fund's financial statements are prepared in accordance with
generally accepted accounting principles, which may require the use of
management accruals and estimates. The following is a summary of significant
accounting policies followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term securities
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked to market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or deducted from)
the basis of the security acquired or deducted from (or added to) the proceeds
of the security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premiums paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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

                                       60
<PAGE>   62
- --------------------------------------------------------------------------------

by the Fund as unrealized gains or losses. When the contract is closed, the Fund
records 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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $430,770 have been reclassified between undistributed
net investment income and accumulated net realized capital losses. These
reclassifications have no effect on net assets or net asset values per share.

2. INVESTMENT ADVISORY AGREEMENT AND
TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which

necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of 1.00% of the average daily value of the Fund's net assets.

  Pursuant to the Distribution Plan adopted by the Company in accordance with
Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the
Distributor an ongoing distribution fee each month at the annual rate of .15% of
the average daily value of the Fund's Class B net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement which limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA. For
the year ended December 31, 1999, MLAM earned fees of $773,462, of which
$327,133 was voluntarily waived.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--DOMESTIC MONEY MARKET FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  For the year ended December 31, 1999, the Domestic Money Market Fund's Class A
Shares had a net annualized yield of 4.84%. For the six-month period ended
December 31, 1999, the Fund's Class A Shares had a net annualized yield of
5.07%. The Fund's Class A Shares' 7-day yield as of December 31, 1999 was 5.50%.
The average portfolio maturity was 61 days at December 31, 1999, compared to 73
days at June 30, 1999.

THE ENVIRONMENT

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the
two-year Treasury note yield hit a two-year high over concerns of the continued
strength of the economy and potential future action by the Federal Reserve
Board. Against the background of still higher interest rates, we positioned the
Fund more conservatively. We expect to continue to concentrate new investments
in the one-month and three-month areas as we wait for a clearer economic picture
to develop.

  The Fund's composition at the end of December and as of our last report to
shareholders is detailed below:

NOTES TO FINANCIALS STATEMENTS

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Domestic Money Market Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities with remaining maturities
of greater than sixty days, for which market quotations are readily available,
are valued at market value. As securities transition from sixty-one to sixty
days to maturity, the difference between the valuation existing on the
sixty-first day before maturity and maturity value is amortized on a
straight-line basis to maturity. Securities maturing sixty days or less from
their date of acquisition are valued at amortized cost, which approximates
market value. For the purposes of valuation, the maturity of a variable rate
security is deemed to be the next coupon date on which the interest rate is to
be adjusted. Other investments for which market quotations are not readily
available are valued at their fair value as determined in good faith by or under
the direction of the Company's Board of Directors.

  (b) Repurchase agreements--The Fund invests in US Government securities
pursuant to repurchase agreements. Under such agreements, the counterparty
agrees to repurchase the security at a mutually agreed upon time and price. The
Fund takes possession of the underlying securities, marks to market such
securities and, if necessary, receives additional securities daily to ensure
that the contract is fully collateralized. If the counterparty defaults and the
fair value of the collateral declines, liquidation of the collateral by the Fund
may be delayed or limited.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income (including amortization of premium and discount) is recognized
on the accrual basis. Realized gains and losses on security transactions are
determined on the identified cost basis.

  (e) Dividends and distributions to shareholders--The Fund declares dividends
daily and reinvests monthly such dividends (net of non-resident alien tax and
back-up withholding tax withheld) in additional Fund shares at net asset value.
Dividends and distributions are declared from the total of net investment income
and net realized gain or loss on investments.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
the annual rate of .50% of the average daily value of the Fund's net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement which limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL BOND FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  During the fiscal year ended December 31, 1999, the total return for Global
Bond Focus Fund's Class A Shares was -8.18%, as compared to -5.08% for the
unmanaged benchmark J.P. Morgan Global Government Bond Index for the same
period.

  During the 12-month period ended December 31, 1999, much of our strategy
centered around adjusting the Fund's duration in response to interest rate
volatility. We shortened our duration in the dollar bloc countries relative to
the Fund's benchmark. We also reduced our exposure to European Monetary Union
("EMU") countries and increased investments in non-EMU countries (the United
Kingdom, Greece, Norway, Denmark and Sweden). At the same time, we reduced the
duration of our EMU investments and extended duration of our non-EMU
investments. We expected interest rates in non-EMU countries to come down to
meet the lower interest rate structure in EMU countries. However, late in the
fiscal year interest rates began to rise in non-EMU countries as well, which
negatively impacted Fund performance. Although our short duration in dollar-bloc
countries helped performance, it was not enough to offset the negative effect of
our European investments.

  In Japan, our underweight position in the yen also hindered Fund performance.
We believed that we were still in a bullish trend for the US dollar relative to
the yen and that this was a correction in the cycle that would soon end. We also
kept a short duration in Japan, anticipating that there would be a rise in
Japanese interest rates as the economy reflated. In fact, the yen got much
stronger and interest rates in Japan declined.

INVESTMENT ENVIRONMENT

  During the fiscal year ended December 31, 1999, there were three major
predominant forces at work in the global bond markets. The first was the Federal
Reserve Board's attempt to preemptively contain inflationary pressures before
they materialized. At the end of June, August and November, the Federal Reserve
Board raised interest rates 25 basis points (0.25%) to ensure a low level of
inflation, which in turn prompted the central banks of several countries to
raise their official interest rates in November. In addition to the United
States, Canada, Australia, New Zealand, Germany, United Kingdom, Denmark and
Sweden raised interest rates between 25 basis points and 50 basis points.

  The second factor influencing market activity was the rebound in the Japanese
economy and the resulting rise in the Japanese yen. Gross domestic product (GDP)
growth was surprisingly strong in the first quarter and positive in the second
quarter when a decline was expected. With this economic rebound there came a
robust stock market.

  The third important market influence was the pervasive weakness of the euro
throughout the period. The euro's weakness was attributed to a poor, but slowly
rising economy. Relative to the United States and Japan, the EMU's economy was
not moving along and inflationary pressures were beginning to emerge. In
addition, eurobond sales by the Japanese, who had been large holders of
eurobonds, hurt the euro even further during the period. As a result, the euro
relative to the yen went from E123.625 on July 1, 1999 to E102.65 on December
30, 1999, a decline of 16.97%. Relative to the US dollar, the euro declined
approximately 3% during the period.

INVESTMENT OUTLOOK

  Federal Reserve Board Chairman Alan Greenspan continues to voice the central
bank's desire to prevent any potential rise in inflation. Even though at present
there are no significant signs of inflation, we believe the Federal Reserve
Board will strive to temper economic growth through a gradual rise in interest
rates. If the US central bank can orchestrate a soft landing and get economic
growth lower, it may preclude significant future monetary policy tightenings in
2000. At the same time, growth is also present in Japan and the country
currently appears to be rebounding out of its deep recession. However, despite
intervention by the Bank of Japan, continued strengthening of the yen could have
an adverse effect on the economic rebound.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL BOND FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Global Bond Focus Fund (the "Fund") is
classified as "non-diversified," as defined in the Investment Company Act of
1940. The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term securities
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked to market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or deducted from)
the basis of the security acquired or deducted from (or added to) the proceeds
of the security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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 Fund as unrealized gains or losses.

                                       85
<PAGE>   87
- --------------------------------------------------------------------------------

When the contract is closed, the Fund records 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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions from capital gains are recorded on the
ex-dividend dates. Distributions in excess of net investment income are due
primarily to differing tax treatments for foreign currency transactions and
post-October losses.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences have been reclassified as follows: $2,006,891 between
accumulated distributions in excess of net investment income and accumulated net
realized capital losses; $1,501,034 between paid-in capital in excess of par and
accumulated distributions in excess of net investment income; and $175 between
paid-in capital in excess of par and accumulated net realized capital losses.
These reclassifications have no effect on net assets or net asset value per
share.

2. INVESTMENT ADVISORY AGREEMENT AND
TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of .60% of the average daily value of the Fund's net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, the Fund paid Merrill Lynch Security
Pricing Service, an affiliate of Merrill Lynch, Pierce, Fenner & Smith
Incorporated, $130 for providing security price quotations to compute the net
asset value of the Fund.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.

DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  During the year, Global Growth Focus Fund increased substantially in terms of
total net assets, from $19.7 million at year-end 1998 to $180.4 million at
December 31, 1999. This increase in net assets represented a significant
increase in net subscriptions to this world stock Fund. For the year ended
December 31, 1999, the total investment return for the Fund's Class A Shares was
+38.69%. This compares to a total return of +24.93% for the unmanaged Morgan
Stanley Capital International (MSCI) World Stock Index for the same period. The
actively managed portfolios in the Lipper Analytical Services Global Funds
Average had a total return of +36.15% during 1999.

  The Fund's equity investments in the top five industry categories as of
December 31, 1999--wireline communications, communications equipment,
electronics, computers and wireless communications--were responsible for the
majority of the Fund's positive absolute and comparative investment returns for
1999. Starting in early July 1999, we started to shift the Fund's focus from a
relatively large investment weighting in the stocks of companies in the banking
and financial, financial services, household products, insurance and
pharmaceuticals sectors to companies in the communications equipment,
electronics and computers industries.

  We also increased the Fund's weighting in companies in Japan where the Fund
has had a relatively modest investment weighting since its commencement of
operations on June 5, 1998. After the second-quarter 1999 business conditions
report for Japan in July 1999, we started to increase the Fund's weighting in
large-capitalization Japanese companies. This report showed that the consumer
sector of the Japanese economy was continuing to increase real spending on a
consecutive quarterly comparison after a significant rebound in the first
quarter of 1999. Also, several global luxury goods retailers reported
stronger-than-expected revenue growth from sales growth in Japan. We anticipate
the possibility of a continued upturn in the consumer spending sector of Japan.
Consequently, during the second half of 1999 we substantially increased the
percentage of the Fund's net assets invested in Japanese stocks. At year-end
1999, the second-largest equity investment in the Fund was the holding of shares
in NTT Mobile Communications Network, Inc. of Japan. In our opinion, real growth
rates of business activity and consumer spending could rise in Continental
Europe and Japan during 2000 if there is an export-led increase in manufacturing
employment in Europe and continued fiscal stimulus from the Japanese government.

IN CONCLUSION

  We appreciate your investment in Global Growth Focus Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to sharing our investment
outlook and strategies with you in our next report to shareholders.

Sincerely,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL GROWTH FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company
("MLLIC"), ML Life Insurance Company of New York (indirect wholly-owned
subsidiaries of Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance
companies, that are not affiliated with ML & Co., for their separate accounts to
fund benefits under certain variable annuity and variable life insurance
contracts. Class A and Class B Shares have equal voting, dividend, liquidation
and other rights, except that only shares of the respective classes are entitled
to vote on matters concerning only that class and Class B Shares bear certain
expenses related to the distribution of such shares. Global Growth Focus Fund
(the "Fund") is classified as "diversified," as defined in the Investment
Company Act of 1940. The Fund's financial statements are prepared in accordance
with generally accepted accounting principles, which may require the use of
management accruals and estimates. The following is a summary of significant
accounting policies followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Short-term securities are valued at
amortized cost, which approximates market value. Futures contracts are valued at
the settlement price at the close of the applicable exchange. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked to market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid or received is added to (or deducted from) the
basis of the security acquired or deducted from (or added to) the proceeds of
the security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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 Fund as unrealized gains or losses.
When the contract is closed, the Fund records a

                                       100
<PAGE>   102
- --------------------------------------------------------------------------------

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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $141,164 have been reclassified between undistributed
net investment income and undistributed net realized capital gains. These
reclassifications have no effect on net assets or net asset value per share.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton

reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL STRATEGY FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  For the year ended December 31, 1999, Global Strategy Focus Fund's Class A
Shares had a total return of +21.37%. Foreign equities provided the highest
return among asset classes during 1999. The Fund's return was enhanced by our
decision to expand foreign equity representation beginning early in the year,
with our focus on enlarging the commitment to Japan and expanding representation
in emerging markets. This increase included the establishment of positions in
Brazil, South Korea and Singapore. The allocation of significant assets to "new
economy" sectors in all markets--including technology, business services,
telecommunications services and telecommunications equipment--also had a
positive effect on the Fund's performance. Within the United States, technology
was the largest sector represented throughout the year, and this allocation
proved rewarding. In contrast to 1998, the return on fixed-income securities
lagged that of equities by a substantial margin, but the negative impact was
limited by a significant reduction in our US bond representation during 1999.

PORTFOLIO MATTERS

  As of December 31, 1999, the asset allocation for Global Strategy Portfolio
was: US stocks, 25% of net assets; foreign stocks, 54%; US bonds, 3%; foreign
bonds, 16%; and cash reserves, 2%.

  Equity representation remained at 79%
of net assets during the six months ended December 31, 1999, but we shifted the
asset mix in favor of foreign equities. We increased the allocation to this
sector from 43% of net assets to 54% during the second half of 1999. We enlarged
the Fund's representation in European technology and business services through
new positions such as Epcos AG, Equant, Getronics NV, Telefonaktiebolaget LM
Ericsson and Tandberg Television ASA. Overall, Europe remains the largest
regional commitment, while Japan continues to be overweighted relative to the
benchmark unmanaged Morgan Stanley Capital International Europe, Australasia,
Far East Index. We increased the Fund's commitment to Asia (excluding Japan)
through positions in City Developments Limited and Singapore Airlines Limited in
Singapore. In Latin America, we continued to focus on Brazil because it offered
the most favorable reward/risk potential, in our view.

  During the six months ended December 31, 1999, we reduced our US equity
position from 36% of net assets to 25%. Our technology holdings accounted for
nearly one-third of the Fund's US equity assets. This commitment reflects our
continuing emphasis on the shares of companies where we believe a consistent and
above-average rate of earnings growth could be extended over the next several
years and where valuations appear to us to be reasonable relative to earnings
growth potential. Consistent with this focus are the Fund's significant
commitments to the consumer staples, communication services, financial and
healthcare sectors.

  In the fixed-income sector, we reduced our position in US bonds from 6% of net
assets to 3% during the six months ended December 31, 1999. Late in 1999, we
took advantage of an interest rate rise to extend the Fund's average duration to
6.8 years, after reducing the duration earlier in the second half of 1999. In
our opinion, the Federal Reserve Board will continue to tighten monetary policy
in 2000 until the US economy slows down. Such a slowdown could

                                       104
<PAGE>   106

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

ease fears of a resurgence of inflation and enable intermediate-term--long-term
US interest rates to decline. At this time, risk in US fixed-income securities
appears limited, in our view. In the foreign bond sector, we increased the
Fund's representation from 13% of net assets to 16% during the second half of
1999. We maintained positions in German and UK bonds throughout the second half
of the year. We reestablished a position in New Zealand bonds during the latter
part of 1999, taking advantage of a widening yield differential between New
Zealand and US bonds of similar maturities.

IN CONCLUSION

  We appreciate your investment in Global Strategy Focus Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to sharing our investment
outlook with you in our next report to shareholders.

Sincerely,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL STRATEGY FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies, that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Global Strategy Focus Fund (the "Fund") is
classified as "non-diversified," as defined in the Investment Company Act of
1940. The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Short-term securities are valued at
amortized cost, which approximates market value. Futures contracts are valued at
the settlement price at the close of the applicable exchange. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked to market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid or received is added to (or deducted from) the
basis of the security acquired or deducted from (or added to) the proceeds of
the security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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 Fund as unrealized gains or losses.
When the contract is closed, the Fund records a

                                       118
<PAGE>   120
- --------------------------------------------------------------------------------

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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Trans-actions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates. Distributions in excess of net investment
income and net realized capital gains are due primarily to differing tax
treatments for foreign currency transactions.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $260,468 have been reclassified between accumulated
distributions in excess of net investment income and undistributed net realized
capital gains. These reclassifications have no effect on net assets or net asset
value per share.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of .65% of the average daily value of the Fund's net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("MLPF&S"), a subsidiary of ML & Co., earned $129,797 in
commissions on the execution of portfolio security transactions.

  For the year ended December 31, 1999, Merrill Lynch Security Pricing Service,
an affiliate of MLPF&S, earned $285 for providing security price quotations to
compute the Fund's net asset value.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.

  Accounting services are provided to the Fund by MLAM at cost.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL UTILITY FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  During the fiscal year ended December 31, 1999, we adhered to the Fund's
stated investment objective of seeking both capital appreciation and current
income. Moreover, we focused our attention on the Year 2000 issue given the
critical importance of the utility sector. As a result, we remained very
underweighted in emerging markets for the year. For the 12 months ended December
31, 1999, the Fund's Class A Shares had a total return of +12.63 %.

  At December 31, 1999, approximately 39.5% of the Fund's net assets was
invested in US-based utilities and 58.1% was invested in non-US based utility
stocks. The majority of the Fund's overseas utility investments were in Europe,
more specifically southern Europe. In terms of sector allocation,
telecommunications was dominant on an overall portfolio basis, particularly in
Europe. This sector is a clear beneficiary of changes in technology. New
technology is not only lowering the cost of doing business but is impacting
overall demand for services through increased Internet usage as well as wireless
telephony. These trends have clearly been positive for the sector and have been
evident in terms of company results.

  For the 12 months ended December 31, 1999, the Fund's performance was
negatively impacted by its holdings in the domestic electric utility sector and
to a lesser extent by its holdings in the domestic natural gas sector. The
defensive characteristics of the domestic electric utility sector worked against
performance as investors sought higher risk growth sectors such as technology.
In general, high-yielding US stocks underperformed the broad market by a wide
margin and the only stocks to show relative outperformance were those with
yields well below the yield of the Standard & Poor's (S&P) 500 Index. Rising
long-term interest rates also contributed negatively because the sector is still
considered to be sensitive to movements in interest rates.

  European utilities had relatively weak performance during most of the fiscal
year ended December 31, 1999, as measured by the Financial Times/S&P Actuaries
World Utilities Index. This was partly in response to the weakness of the euro
relative to the US dollar, which started at E1.1585 on January 8, 1999, dropped
to E1.0684 on September 30, and finished the fiscal year at E1.0062 as of
December 31, 1999. However, in the fourth quarter of the Fund's fiscal year, the
European utility sector started to rebound as investors once again focused on
fundamentals and attractive asset bases. Moreover, companies are beginning to
unlock value by disposing of non-core assets and by listing faster-growing
businesses in the market. As of December 31, 1999, the value of the euro
compared to the US dollar appeared to be of a lesser concern.

  During the Fund's fiscal year, there was a rebound in Pacific Basin-based
utility stocks, particularly in Japan. The Japanese utility sector primarily
benefited from the strength in the local market. The Fund's exposure to the
Japanese market is in the major telephone company, Nippon Telegraph & Telephone
Corporation (NTT).

IN CONCLUSION

  We appreciate your investment in Global Utility Focus Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to

                                       122

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL UTILITY FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Global Utility Focus Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term securities
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write call and put options and purchase put options.
When the Fund writes an option, an amount equal to the premium received by the
Fund is reflected as an asset and an equivalent liability. The amount of the
liability is subsequently marked to market to reflect the current market value
of the option written. When a security is purchased or sold through an exercise
of an option, the related premium paid (or received) is added to (or deducted
from) the basis of the security acquired or deducted from (or added to) the
proceeds of the security sold. When an option expires (or the Fund enters into a
closing transaction), the Fund realizes a gain or loss on the option to the
extent of the premiums received or paid (or gain or loss to the extent the cost
of the closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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 Fund as unrealized gains or losses.
When the contract is closed, the Fund records a

                                       132
<PAGE>   134
- --------------------------------------------------------------------------------

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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Trans-
actions denominated in foreign currencies are recorded at the exchange rate
prevailing when recognized. Assets and liabilities denominated in foreign
currencies are valued at the exchange rate at the end of the period. Foreign
currency transactions are the result of settling (realized) or valuing
(unrealized) assets and liabilities expressed in foreign currencies into US
dollars. Realized and unrealized gains or losses from investments include the
effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Deferred organization expenses--Deferred organization expenses are charged
to expense on a straight-line basis over a period not exceeding five years.

  (g) Dividends and distributions--Dividends from net investment income are
declared and paid quarterly. Distributions of capital gains are recorded on the
ex-dividend date.

  (h) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $839 have been reclassified between undistributed net
investment income and undistributed net realized capital gains. These
reclassifications have no effect on net assets or net asset value per share.

2. INVESTMENT ADVISORY AGREEMENT AND
TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton

necessary personnel, facilities, equipment and certain other services necessary

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a subsidiary of ML & Co., earned $6,962 in commissions on the
execution of portfolio security transactions for the Fund.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GOVERNMENT BOND FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  For the 12-month period ended December 31, 1999, the Fund's Class A Shares had
a -1.80% total return as compared to a total return of -0.59% for the unmanaged
Salomon Smith Barney Government/Mortgage Index and an average total return of
- -2.15% for the Lipper Annuity U.S. Government Group. The Fund began using as its
benchmark the Salomon Smith Barney Government/Mortgage Index on July 1, 1999,
following the inclusion of mortgage-backed securities into the Fund's expanded
prospectus language. Prior to that, the Fund had used as a benchmark the
unmanaged Merrill Lynch US Treasury/Agency Master Index. Since adopting the new
Index on July 1, 1999, the Fund outperformed the benchmark, on a gross basis, by
0.17%. With respect to the Fund's performance relative to the Lipper Annuity
U.S. Government Group, the Fund's excess performance is directly attributable to
its overweighted position in mortgage-backed securities. The Fund also benefited
from its emphasis on higher coupon issues that tend to outperform during periods
of rising interest rates.

PORTFOLIO MATTERS

  During the six-month period ended December 31, 1999, we initially went to a
market-weighted position in mortgage-backed securities, relative to the Salomon
Government/ Mortgage Index. During the final quarter of 1999, our
mortgage-backed position shifted to a 10% overweighting compared to the Index.
We overweighted positions in agency debentures at the expense of Treasury
securities. Although the timing of this bias initially hurt relative performance
as yield spreads widened, the breakeven attributes (the total return given the
level of yield differences) were extremely favorable. In fact, during late
August and early September, yield spreads began to contract, a situation that
accelerated during the latter half of the six-month period. Fortunately, the
spread overweighting was taken in the shorter maturity agencies, which tend to
perform better than longer-term agency issues in a spread-widening environment.

  With respect to mortgage-backed securities, we remained committed to highly
liquid collateralized mortgage obligations. Also, we concentrated on keeping
coupon levels high. As a result, the Fund's Class A Shares returned +0.48% for
the six months ended December 31, 1999, as compared to its Lipper Annuity U.S.
Government peer group average of +0.06%.

  Going forward, we believe that the current high-yield levels available on
agency debentures and mortgage-backed securities are attractive. Over long
periods of time, we believe agency debentures are likely to perform better than
Treasury debt given their yield advantage and very similar credit quality.
Therefore, we expect to continue to overweight the portfolio in agency
debentures, preferably in maturities in the five-year-ten-year area. With
respect to mortgage-backed securities, we plan to maintain our 10% overweighted
position relative to the Index, given our belief that a low prepayment
environment should translate into outperformance for this sector. From an
interest rate perspective, we believe that the Federal Reserve Board is likely
to continue to tighten monetary policy in an attempt to keep inflation under
control.

IN CONCLUSION

  We appreciate your investment in Government Bond Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to sharing our investment
outlook and strategy with you in our next report to shareholders.

Sincerely,

/s/ Terry K. Glenn

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GOVERNMENT BOND FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies, that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Government Bond Fund (the "Fund") is classified
as "diversified," as defined in the Investment Company Act of 1940. The Fund's
financial statements are prepared in accordance with generally accepted
accounting principles, which may require the use of management accruals and
estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Short-term securities are valued at amortized cost, which approximates
market value. Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Directors of the Company.

  (b) Repurchase agreements--The Fund invests in US Government securities
pursuant to repurchase agreements. Under such agreements, the counterparty
agrees to repurchase the security at a mutually agreed upon time and price. The
Fund takes possession of the underlying securities, marks to market such
securities and, if necessary, receives additional securities daily to ensure
that the contract is fully collateralized. If the counterparty defaults and the
fair value of the collateral declines, liquidation of the collateral by the Fund
may be delayed or limited.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income (including amortization of premium and discount) is recognized
on the accrual basis. Realized gains and losses on security transactions are
determined on the identified cost basis.

  (e) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates. Distributions in excess of net investment income are due
primarily to differing tax treatments for post-October losses.

  (f) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $386,858 have been reclassified between accumulated net
realized capital losses and undistributed net investment income. These
reclassifications have no effect on net assets or net asset value per share.

2. INVESTMENT ADVISORY AGREEMENT AND
TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
the annual rate of

                                       145
<PAGE>   147
- --------------------------------------------------------------------------------

 .50% of the average daily value of the Fund's net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, Merrill Lynch Security Pricing Service,
an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, a subsidiary
of ML & Co., earned $3,194 for providing security price quotations to compute
the Fund's net asset value.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.
  Accounting services are provided to the Fund by MLAM at cost.
  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

3. INVESTMENTS:

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--HIGH CURRENT INCOME FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

MARKET REVIEW

  In the aftermath of the Asian crisis and Russian default, high-yield investors
began 1999 in a cautious mode. Nevertheless, with a healthy economy as a
backdrop, mutual funds flows were positive in 14 of the first 21 weeks of the
year. Newly created collateralized bond obligations (CBOs) were another source
of buying power. As a result, new issues were generally well received. Two large
transactions in excess of $1 billion--Charter Communications Holdings and
Lyondell Chemical--were readily absorbed by the market.

  Unfortunately, the tide began to turn in mid-May as the Federal Open Market
Committee (FOMC) moved to a tightening bias and in June effected the first of
three interest rate hikes. Predictably, new issuance fell off, and from mid-May
through June, the market suffered through six straight weeks of mutual fund
outflows. Secondary market making by dealers dried up.

  In July, the market regained momentum as the FOMC's adoption of a neutral bias
brought investors back. Fund flows turned positive, and the market again was
able to absorb two huge transactions--United Pan-European Communications and
Allied Waste North America. Investor sentiment quickly turned, perhaps as a
result of two large satellite credit defaults in August. The August through
October period was brutal, as the high-yield market registered negative total
returns each month, while funds flows were negative in 13 out of 14 weeks.

  The month of November brought a strong rebound, spurred by a rally in the
equity markets and reduced inflationary fears as the FOMC effected its third
rate increase. The second-largest weekly inflow into high-yield mutual funds
emboldened issuers. Three seasoned telecommunications credits--VoiceStream
Wireless Corporation/Voicestream Wireless Holding Corporation, Nextel
Communications, Inc. and Global Crossing Holding Ltd.--each priced more the $1
billion in new bonds during the month. The positive trend continued into
December, as the market registered another positive return, while new-issue
volume wound down.

  For the year, new-issue volume totaled $94.7 billion, down 32% from 1998, but
still the third largest in the market's history. Media/ telecommunications
continued the trend of recent years as the dominant sector, accounting for over
40% of new-issue volume. Fund flows for the year were negative $836 million,
which was the worst year since 1994. Clearly, pension funds, insurance
companies, equity funds, crossover buyers and CBOs took up the slack.

  As a result, the high-yield market ended up posting its second consecutive low
single-digit return for the year, which is unprecedented in a nonrecessionary
climate.

FISCAL YEAR IN REVIEW

  Besides being buffeted by the unfortunate combination of mutual fund outflows
and rising US Treasury yields, which increased by almost 180 basis points
(1.80%) during the year, the high-yield market suffered its worst year in terms
of defaults since the recession year of 1991. In contrast to the defaults of
that era, 1999's defaults were dominated by business plan failures or driven by
changes in Government policies, as witnessed in the healthcare sector. (The
collapse in oil prices also contributed to the demise of several credits.)
According to data compiled by Donaldson, Lufkin & Jenrette Securities Corp., a
leading underwriter of high-yield bonds, the high-yield market recorded a
default rate of 4.02% for 1999, up from 1.28% in 1998. In the peak year of 1991,
the tally was 8.80%. Data compiled by Edward Altman of New York University's
Stern School showed a similar trend. While a recent survey by the Federal
Reserve Board showed that more senior bank lending officers were tightening
rather than easing lending standards (thus making life more difficult for
marginal credits), we believe that the default rate may have peaked. Our belief
stems from two factors. First, the new-issue mix in 1999 showed an improvement
in the credit quality of new transactions. Second, the recovery in commodity
prices--oil, paper and pulp, and metals--may bode well for credits in those
sectors. We would also remind investors that the default rate often is a lagging
indicator.

  Against this backdrop, the Fund's Class A Shares recorded a total return of
+5.95% for the fiscal year ended December 31, 1999, which compared favorably to
the unmanaged Credit Suisse First Boston Global High Yield Bond Index's total
return of +3.28%. While lackluster by historical standards, the 1999 return
looked quite good relative to the ten-year US Treasury return of -8.43%. For the
six months ended December 31, 1999, the Fund's Class A Shares recorded a total
return of +2.16%, as compared to +0.45% for the Index. The Fund's superior

performance relative to the Index stemmed from several factors. First, the Fund
was overweighted in emerging markets bonds (12.9% as compared to 7.6% for the
Index), which rebounded smartly from last year's selloff. Second, the Fund
benefited from its overweightings in the paper/packaging, cable and
utility/independent power producer sectors, all of which posted strong returns
overall for the year and in particular during the second half. Finally,
benefiting Fund performance were its underweightings in the supermarket/drug,
entertainment and consumer/manufacturing sectors, all of which posted negative
returns for both the 12-month and six-month periods ended December 31, 1999. Our
very modest exposure to the textile sector was also helpful, as many bonds in
this ailing industry were pummeled.

  Individual credit selection was also very important. Thanks to our staff of
research professionals, we managed to avoid the majority of the year's credit
disasters, including the two large satellite credits that filed for Chapter XI
in August. On the plus side, positive event risk also enhanced the Fund's
return. Among the events helping Fund performance were Sprint's takeover of
American Telecasting, which caused its bonds to soar from distressed levels to
about 105% of par; investment-grade Mannesmann AG's takeover bid for Orange PLC,
a major Fund holding; Tekni-Plex, Inc.'s announcement that it planned a
recapitalization, which would likely result in a tender for its two bond issues,
one of which is among the Fund's top ten holdings; and Lyondell Chemical
Company's announcement of a huge asset sale.

  During the latter half of the year, we focused most of our new-issue activity
on large credits, since we believed this was the approach to take given the
limited liquidity provided by dealers. We were also quite selective since the
Fund was somewhat cash constrained. Our major new-issue purchases were the bonds
of ASAT Finance (an affiliate of a semiconductor manufacturer), Blount Inc. (a
diversified manufacturing concern that essentially went private), ICN
Pharmaceutical Inc. (a manufacturer of a broad variety of prescription and
non-prescription pharmaceuticals) and Tapco International Corporation (a small
manufacturer of building trim with strong cash flow margins). In the secondary
market, we established a new position in Corning Consumer Products at a large
discount to par, and added to existing positions in Amkor Technologies Inc. and
Autopistas del Sol SA. The latter is an Argentine toll road operator with
positive momentum, yet its bonds still trade at a substantial discount.

  Our major sales were two media concerns--Hollinger International Publishing,
Inc. and Garden State Newspapers--where fundamentals had started to deteriorate,
in our view. We also exited ASAT Finance since we believed the bond had become
fully valued.

  At year-end, communications and media remained our largest broad industry
category, equaling 26.7% of the Fund's total market value. Of the more narrowly
classified sectors, the largest industries were: communications, 12.2% of the
market value; utilities/independent power producers, 10.9%; cable (domestic &
international), 10.1%; and packaging/paper & forest products, 9.4%. Foreign
bonds comprised 25.5% of the Fund, with emerging market issues (mostly Latin
American corporate bonds) accounting for 12.9% of market value. At December 31,
1999, the average portfolio maturity was 6 years, 11 months, and cash and cash
equivalents amounted to 8.4% of market value.

INVESTMENT OUTLOOK

  Looking ahead, we are optimistic on the outlook for the high yield market in
2000. There are currently several fundamental and technical factors that are
encouraging. Given that almost 70% of the universe is trading at a discount to
par, and with an increasing percentage of bonds callable in the next three
years, we would expect bond retirements to rise this year. While we would not
expect to see much in the way of retail mutual funds flows, we could see new
money from institutional and CBO buyers in 2000. The continued lure of the
equity markets may make it difficult for the high-yield market to attract retail
money back until at least a few months of positive returns have been posted. In
addition, at present the general economy is expected to remain healthy. On the
supply side, many capital hungry high-yield credits are gaining access to
private and public equity, vendor financing, and convertible and bank debt.

IN CONCLUSION

  We thank you for your continued interest in High Current Income Fund of

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies, which
are not affiliated with ML & Co., for their separate accounts to fund benefits
under certain variable annuity and variable life insurance contracts. Class A
and Class B Shares have equal voting, dividend, liquidation and other rights,
except that only shares of the respective classes are entitled to vote on
matters concerning only that class and Class B Shares bear certain expenses
related to the distribution of such shares. High Current Income Fund (the
"Fund") is classified as "diversified," as defined in the Investment Company Act
of 1940. The Fund's financial statements are prepared in accordance with
generally accepted accounting principles, which may require the use of
management accruals and estimates. The following is a summary of significant
accounting policies followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Short-term securities are valued at amortized cost, which approximates
market value. Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Directors of the Company.

  (b) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

  (c) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (d) Dividends and distributions to shareholders--Dividends from net investment
income are declared and paid monthly. Distributions from capital gains are
recorded on the ex-dividend dates. Distributions in excess of net investment
income are due primarily to differing tax treatments for post-October losses.

  (e) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $451,516 have been reclassified between accumulated net
realized capital losses and undistributed net investment income. These
reclassifications have no effect on net assets or net asset value per share.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
based upon the aggregate daily value of net assets of the Fund and the Company's
Prime Bond Fund at the following annual rates: .55% of such average daily net
assets not exceeding $250 million; .50% of such average daily net assets in
excess of $250 million but not more than $500 million; .45% of such average
daily net assets in excess of $500 million but not more than $750 million; and
 .40% of such average daily net assets in excess of $750 million. For the year
ended December 31, 1999, the aggregate average daily net assets of the Fund and
Prime Bond Fund was approximately $1,084,230,000.

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

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, Merrill Lynch Security Pricing Service,
an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, a subsidiary
of ML & Co., earned $1,774 for providing security price quotations to compute
the Fund's net asset value.
  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.
  Accounting services are provided to the Fund by MLAM at cost.
  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

MERRILL LYNCH VARIABLE SERIES--INDEX 500 FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  The Standard & Poor's 500 (S&P 500) Composite Index had another extraordinary
year in 1999 with a total return of +21.04%. The backdrop of this strong
performance was a continued robust US economy, a global economic recovery, and
increasing bond yields and interest rates despite little evidence of actual
inflationary pressures. Topped off by a strong fourth-quarter rally, the Index
advanced for an unprecedented fifth consecutive year with annual returns in
excess of 20%. The last quarter of 1999 turned into a remarkable period for the
Index as it posted a total return of +14.88%, despite the narrowness of the
gains within the Index's universe of component stocks, which were centered
around its largest-capitalization growth stocks. In addition, 1999 became the
ninth-straight year in which the Index had a positive total return. For the
three-year and five-year periods ended December 31, 1999, the S&P 500 Index had
annual total returns of +27.56% and +28.54%, respectively.

  The S&P 500 Index closed the first half of 1999 at an all-time high of
1,372.71 amid indications of a broadening out of recent return patterns in the
market as small and mid cap stocks posted strong returns in the year's second
quarter. In the second half of the year, although continued strong corporate
earning was coupled with still-tame inflationary data, the Index was mostly
confined in a trading range between 1,250 and 1,400. After the Index first
surpassed the 1,400 level in July, the second half of the year began with three
straight months of negative returns. However, this was followed by three
straight positive months, with the market ending the year on a very strong note
as the Index advanced by more than 80 points in December to finish the year at
an all-time high of 1,469.25. For the six and 12-month periods ended December
31, 1999, the S&P 500 Index posted total returns of +7.71% and +21.04%,
respectively. For the year as a whole, large-capitalization and growth stocks
once again provided strong leadership for the market, in particular the S&P
technology sector, which led all groups by outperforming the overall Index by
14.7 percentage points.

  For the year ended December 31, 1999, the Fund's Class A Shares had a total
return of +20.50%, compared to the unmanaged S&P 500 Index's total return of
+21.04% for the same 12-month period. Net assets of Index 500 Fund grew from
$403.2 million on December 31, 1998 to $586.4 million on December 31, 1999, an
increase of 45.4% during the year. Nearly all of the Fund's assets are in a
fully replicating portfolio of all 500 stocks in the S&P 500 Index. Incremental
cash inflows are typically invested through the use of S&P 500 futures
contracts. At December 31, 1999, the Fund's equity portfolio was valued at
$578.7 million, which represented 98.7% of the Fund's net assets. In addition,
the Fund held a long position of 18 S&P 500 March 2000 futures contracts.
Through its holding of equities and futures contracts, it is the Fund's goal to
be 100% invested in the S&P 500 Index at all times.

  We added a number of new equity positions to the Fund during the second half
of 1999, as Standard & Poor's revised its list in response to merger and
acquisition activity involving constituents within the Index. This activity
continued at a rapid pace throughout the last half of 1999. During this time, we
added to the Fund's portfolio: QUALCOMM Incorporated, ADC Telecommunications,
Inc., Allied Waste Industries, Inc., Conoco Inc. (Class B), Lexmark
International Group, Inc. (Class A), Tosco Corporation, Global Crossing Ltd.,
Bed Bath & Beyond Inc., Adaptec, Inc., Pinnacle West Capital Corporation, Analog
Devices, Inc., The Home Depot, Inc., T. Rowe Price Associates, Inc., Leggett &
Platt, Incorporated, El Paso Energy Corporation, Comverse Technology, Inc.,
Pactiv Corporation, Xilinx, Inc., Teradyne, Inc., Quintiles Transnational Corp.,
Molex Incorporated, Citrix Systems, Inc., Old Kent Financial Corporation,
Honeywell International Inc., Yahoo! Inc. and Transocean Sedco Forex Inc.

IN CONCLUSION

  We appreciate your investment in Index 500 Fund of Merrill Lynch Variable
Series Funds, Inc., and we look forward to assisting you with your investment
needs in the months and years ahead.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--INDEX 500 FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc.("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Index 500 Fund (the "Fund") is classified as
"non-diversified," as defined in the Investment Company Act of 1940. The Fund's
financial statements are prepared in accordance with generally accepted
accounting principles, which may require the use of management accruals and
estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
sale price prior to the time of valuation. Securities traded in the NASDAQ
National Market System are valued at the last sale price prior to the time of
valuation. Portfolio securities that are traded both in the over-the-counter
market and on a stock exchange are valued according to the broadest and most
representative market. Options written or purchased are valued at the last sale
price in the case of exchange-traded options. In the case of options traded in
the over-the-counter market, valuation is the last asked price (options written)
or the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term securities
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity markets. Losses may arise due to changes in the
value of the contract or if the counterparty does not perform under the
contract.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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 Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

- - Options--The Fund is authorized to purchase and write covered call and put
options. When the Fund writes an option, an amount equal to the premium received
by the Fund is reflected as an asset and an equivalent liability. The amount of
the liability is subsequently marked to market to reflect the current market
value of the option written. When a security is purchased or sold through an
exercise of an option, the related premium paid (or received) is added to (or
deducted from) the basis of the security acquired or deducted from (or added to)
the proceeds of the security sold. When an option expires (or the Fund enters
into a closing transaction), the Fund realizes a gain or loss on the option to
the extent of the premiums received or paid (or gain or loss to the extent the
cost of the closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of

                                       176
<PAGE>   178

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

settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Deferred organization expenses--Deferred organization expenses are charged
to expense on a straight-line basis over a period not exceeding five years.

  (g) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates. Distributions in excess of realized
capital gains are due primarily to differing tax treatments for futures
transactions and post-October losses.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--INTERNATIONAL EQUITY FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  During the 12-month period ended December 31, 1999, the vast majority of
equity markets, both developed and emerging, rose in US dollar terms. Over this
period, the Fund's benchmark, the unmanaged Morgan Stanley Capital International
(MSCI) World (Ex-US) Index, rose 27.93%, while International Equity Focus Fund's
Class A Shares returned +37.63%. Essentially all aspects of our investment
decision process contributed to this outperformance. However, there were two
primary contributors to the success. First, the Fund benefited because we
correctly decided to switch from growth-style stocks to more cyclical or
value-oriented stocks at the end of 1998 before deciding to switch back at the
beginning of the fourth calendar quarter of 1999. Second, stock selection has
been successful throughout the year, especially in Japan. The Fund also
benefited from selective positions in emerging markets, which are not included
in the Fund's benchmark. Emerging markets continued to rebound in 1999 against a
background of stronger global economic growth and a rally in commodity prices,
especially oil, which reached a nine-year high of $27 per barrel. (References to
securities markets of all countries in this letter to shareholders correspond to
those countries' market weightings in the MSCI World (Ex-US) Index, unless
otherwise noted.)

  The year was characterized by strong returns from most equity markets in local
currency terms. However, the effects of exchange rate volatility have increased
the spread of returns to US dollar investors. The Japanese yen strengthened by
10% over the year ended December 31, 1999, enhancing returns to dollar investors
from yen-denominated assets. In stark contrast, the euro, the new European
currency introduced at the beginning of 1999, depreciated by nearly 15% relative
to the dollar, undermining the local currency gains made by the markets in the
Eurozone.

  During 1999 the global economy picked up, partly in response to the monetary
easing initiated in the fourth quarter of 1998 by the US Federal Reserve Board
and other central banks. In particular, the US economy grew strongly,
experiencing its eighth consecutive year of expansion. The unemployment rate hit
a 29-year low, raising inflationary fears and pushing the long-term bond yield
up to 6.5%. Meanwhile, the Japanese economy grew again after a sharp contraction
in 1998, supporting the wider recovery in Asia. In Europe, the weak euro aided
faster growth in the second half of the year.

  The strength of the global economic pick-up rekindled the concerns of
inflation in the minds of Western central bankers. Their reactions were to raise
interest rates in the United States by 75 basis points (0.75%) and in the United
Kingdom and Euroland by 50 basis points each. The Bank of Japan was the only
leading central bank not to raise interest rates, preferring to keep its zero
interest rate policy in place to stimulate economic activity and to try to
prevent further strengthening of the yen.

  The Asian region provided the highest returns from developed markets over the
12 months ended December 31, 1999, in aggregate rising by 62% over the fiscal
year, while emerging Asian markets rose 70%. Within the developed markets,
Japan, Hong Kong and Singapore Free all returned about 60%. The Japanese market
was boosted not only by cyclical economic recovery but also by increasing
evidence of companies making concerted efforts to raise their return on equity
through labor cost reductions, capital spending cutbacks, share buybacks and
even merger and acquisition (M&A) activity.

  Emerging equity markets in Europe and Latin America also produced strong
performance, continuing the recoveries started in the latter part of 1998.
Emerging Europe returned +84% over the year ended December 31, 1999, with Turkey
and Russia returning approximately +250%. The Latin American region gained +65%,
with the best returns coming from Mexico and Brazil. (Returns for emerging
equity markets correspond to those countries' market weightings in the MSCI
Emerging Markets Index.)

  Developed European markets produced quite diverse returns. Finland (+153%) and
Sweden (+80%) were the star performers but six European markets (including
Switzerland and Italy) produced negative returns in US dollar terms. The main
driver of these relative returns was sector composition, with those markets
containing a strong technology bias producing strong returns, while those with a
high weighting of utilities and financials generally lagged well behind.

PORTFOLIO MATTERS

  For most of the fiscal year ended December 31, 1999, the Fund was
underweighted in the Continental European area, which was beneficial to the Fund
since this

                                       180
<PAGE>   182
- --------------------------------------------------------------------------------

region lagged other regions in performance terms. In the early part of the
fourth quarter, we started to increase the Fund's exposure to Continental
European equities, becoming overweighted by the end of October. We achieved this
largely at the expense of Japanese exposure. Our shift away from Japan toward
Europe during the last three months proved timely. In local currency terms,
Europe outperformed Japan by more than 12% over the three months ended December
31, 1999. However, once currency movements are taken into account, Europe's
outperformance was reduced to around 2%.

  The Fund started the year overweight in the UK market, but by the middle of
the second quarter we had reversed this position and the United Kingdom remained
underweight relative to the benchmark for the rest of the year. This was
beneficial to the Fund since the United Kingdom has been one of the poorer
performing markets, returning +12.0% for the year ended December 31, 1999.

  In Japan, during the first half of the year the Fund moved from a slightly
underweighted to slightly overweighted position relative to the benchmark. (This
represented a higher weighting than most international funds throughout the
period.) Part of the increase in the allocation to Japanese equities was
directed to the smaller-companies section of the market. This proved
particularly successful since the local smaller companies' index (Tokyo Stock
Exchange Index, Second Section) outperformed the larger companies' MSCI Japan
Index markedly in the second and third quarters of the year. During the last
quarter of the year, we took profits on the small companies' portfolio and as a
result reduced the overall exposure to Japan to below benchmark weight. Overall,
Japan was the largest country exposure in the Fund, averaging around 22% of net
assets over the year.

IN CONCLUSION

  An environment of possibly stronger economic growth in nearly all markets
coupled with a potentially subdued inflationary outlook can provide a good
backdrop for international equities.

  During the six months ended December 31, 1999, the return from developed
markets outside the United States exceeded the return from the US market by 14%
(in US dollar terms). This is the first six-month period since 1994 that
international markets have produced such a significant outperformance of the US
domestic market.

  The cyclical case for international markets is based on what may be an
economic recovery in the rest of the world arriving at a time when US growth may
be peaking. Of course, a lower US dollar adds to the returns from international
investment.

  We are also seeing that value has favored international equities. Ten years
ago, price/book and price/cash earnings ratios in the United States were only
around 75% of those in the MSCI World (Ex-US) Index, while the dividend yield
was almost double. Now those two ratios are much higher in the United States:
the price/ book value ratio is 5.0 versus 2.8 internationally. At the same time,
the dividend yield is lower.

  We appreciate your investment in International Equity Focus Fund of Merrill
Lynch Variable Series Funds, Inc., and we look forward to sharing our investment
outlook and strategies with you in our next report to shareholders.

Sincerely,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--INTERNATIONAL EQUITY FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. International Equity Focus Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term securities
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Interest rate swaps--The Fund is authorized to enter into equity swap
agreements, which are over-the-counter contracts in which one party agrees to
make periodic payments based on the change in market value of a specified equity
security, basket of equity securities or equity index in return for periodic
payments based on a fixed or variable interest rate or the change in market
value of a different equity security, basket of equity securities or equity
index. Swap agreements may be used to obtain exposure to an equity or market
without owning or taking physical custody of securities in circumstances in
which direct investment is restricted by local law or is otherwise impractical.

- - Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked to market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid or received is added to (or deducted from) the
basis of the security acquired or deducted from (or added to) the proceeds of
the security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the

                                       198

<PAGE>   200
- --------------------------------------------------------------------------------

purpose of hedging the market risk on existing securities or the intended
purchase of securities. Futures contracts are contracts for delayed delivery of
securities at a specific future date and at a specific price or yield. Upon
entering into a contract, the Fund deposits and maintains as collateral such
initial margin as required by the exchange on which the transaction is effected.
Pursuant to the contract, the Fund agrees 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 Fund
as unrealized gains or losses. When the contract is closed, the Fund records 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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Trans-actions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates. Distributions in excess of net investment
income are due primarily to differing tax treatments for post-October losses.
Distributions in excess of realized capital gains are due primarily to differing
tax treatments for futures and foreign currency transactions.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $261,248 have been reclassified between accumulated net
realized capital losses and accumulated distributions in excess of net
investment income. These reclassifications have no effect on net assets or net
asset value per share.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

THE BOARD OF DIRECTORS AND SHAREHOLDERS,
INTERNATIONAL EQUITY FOCUS FUND OF
MERRILL LYNCH VARIABLE SERIES FUNDS, INC.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of International Equity Focus Fund of Merrill Lynch
Variable Series Funds, Inc. as of December 31, 1999, the related statements of
operations for the year then ended and changes in net assets for each of the
years in the two-year period then ended, and the financial highlights for each
of the years in the five-year period then ended. These financial statements and
the financial highlights are the responsibility of the Fund's management. Our

test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at December
31, 1999 by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of International Equity

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--NATURAL RESOURCES FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  During the 12 months ended December 31, 1999, the Fund's Class A Shares had a
total return of +26.77%. The Fund outperformed the +24.60% total return of the
unmanaged Morgan Stanley Capital International (MSCI) Natural Resource Fund
Index. Additionally, the Fund's Class A Shares' total return exceeded the
+25.65% return of the Lipper Natural Resources Fund Group average and the
+24.67% return for the Lipper Natural Resources Annuity Group average.

  We continued to follow a strategy of identifying commodity sectors with rising
capacity utilization trends and selecting attractively valued companies within
favored sectors. Early in 1999, we identified favorable trends in North American
natural gas markets, as well as selected paper and forest products. We
overweighted these sectors in the Fund, largely at the expense of the chemical
sector, where rising energy feedstock costs and excess capacity were expected to
result in margin pressures for chemical producers. This strategy generated
favorable absolute and relative returns for the Fund through October 1999, as
many natural gas and paper stocks delivered dramatic double-digit returns. The
chemical sector, suffering from our forecast of margins pressures and earnings
disappointments, lagged almost all other commodity groups.

  The Fund's performance stagnated during the fourth quarter of 1999, despite
generally rising commodity prices. While selected paper stocks continued to
deliver strong relative and absolute performance, we surrendered significant
gains in our natural gas holdings as the winter heating season started with
temperatures averaging 25% warmer than normal. This unseasonably warm start to
winter was even greater than the record warm start to the 1998--1999 heating
season, and resulted in the Fund falling sharply from the strong gains it
delivered during the first ten months of 1999. However, the fundamental outlook
for energy stocks remains favorable, and we intend to maintain the Fund's
exposure to oil, oil service and natural gas leveraged companies. OPEC has
continued to maintain solid compliance with its production quotas set in March
1999. This is leading to a rapid fall in global inventories, as economic
activity remains robust in the United States and continues to recover in Asia.
With oil prices currently above $25 per barrel, profits from oil and gas
production are likely to post strong earnings gains. We also believe that
refining margins have the potential to recover, as global gasoline and heating
oil inventories are reduced. However, it is likely that this recovery will be
slower since surplus capacity constructed in Asia in recent years needs to be
absorbed by rising consumption in the region. Nonetheless, as the large surplus
supplies continue to be reduced, gasoline prices have the potential to rally
during the upcoming summer driving season. Petrochemical prices have also shown
strength in 2000; however, we remain concerned that further gains may be muted
by the construction of new petrochemical plants in Canada and the Middle East.

  The valuation of energy sector stocks remains highly attractive when compared
to historic relative benchmarks. Large-capitalization stocks are trading at near
record low relative price/ earnings and dividend yields. In addition, we believe
that earnings will likely recover in the oil service sector, as drilling
expenditures resume following a release of budget constraints set during last
year's oil price weakness, and as recently merged energy companies turn to their
core businesses following consolidation and restructuring activities. Finally,
North American natural gas producers continue to have a favorable supply and
demand outlook, provided normal weather patterns return. North American natural
gas storage continues to run below year ago levels, so normal withdrawal rates
for the remainder of the year could drive gas prices back to the $2.50 per
thousand cubic feet range that prevailed last year. However, we will be
monitoring demand and supply factors closely in this sector.

  We also sold all of the Fund's gold holdings by the end of 1999. This had a
generally favorable impact on Fund performance, as gold stocks have continued to
languish in the current benign inflation environment, and from ongoing sales
from various central banks. While we believe that there is the potential for
commodity inflation to accelerate in 2000, we believe that other commodity
investments may offer a better inflation hedge than gold. Gold's failure to
exhibit its defensive characteristics during the recent periods of economic
uncertainty and unrest has dimmed its investment appeal, in our view.

  We continue to maintain a relatively high exposure to the paper and forest
products industry. Positive supply and demand fundamentals continued to exert
themselves in several forest and paper products, and price

                                       202
<PAGE>   204
- --------------------------------------------------------------------------------

increases have been announced across several products. The industry continues to
maintain capital spending discipline, and we believe that there is the potential
for further consolidation among companies in this sector. We are inclined to
continue our overweighting of paper and forest product stocks, although we did
sell some of our holdings to companies leveraged to lumber production. While
housing starts remain strong, we are concerned that higher interest rates may
slow the pace of new home construction. Therefore, we sold our long-term
holdings in Riverside Forest Products Ltd. and Slocan Forest Products Ltd.

  In the metals/mining sector, we continued to hold a neutral weighting relative
to the MSCI Natural Resource Index during the year. Alcoa Inc. was the best
performer in this sector, with a total return exceeding 100% during the year.
Good gains were also achieved in Fund holdings M.I.M. Holdings Limited and WMC
Limited in Australia. While we expect these stocks to continue to perform well
in sympathy with strong global economic growth, we continue to fear that idled
capacity could return to global markets should metal prices continue to rally.

INVESTMENT OUTLOOK

  Should the trend in improving global economic conditions persist, we believe
that the Fund could continue to enjoy positive investment results in the first
year of the new millennium. The energy and forest products sectors continue to
show the best supply and demand fundamentals, so we are maintaining our
concentrations in these sectors. However, we have been marginally increasing our
oil service exposure, as these stocks appear to have stronger earnings growth
profiles as we progress to the second half of the year. We continue to be
confident that our investment focus on companies subject to improving supply and
demand conditions will generate strong relative and absolute returns. While the
unseasonably warm start to winter surrendered some of the year's strong gains,
we believe that valuations of resource sector stocks are compelling at current
levels and continue to be optimistic that resource investments will deliver a
positive contribution to a diversified investment portfolio.

IN CONCLUSION

  We appreciate your investment in Natural Resources Focus Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to sharing our investment
outlook and strategies with you in our next report to shareholders.

Sincerely,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--NATURAL RESOURCES FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Natural Resources Focus Fund (the "Fund") is
classified as "non-diversified," as defined in the Investment Company Act of
1940. The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written or purchased are valued at the last sale price in the
case of exchange-traded options. In the case of options traded in the
over-the-counter market, valuation is the last asked price (options written) or
the last bid price (options purchased). Futures contracts are valued at the
settlement price at the close of the applicable exchange. Short-term investments
are valued at amortized cost, which approximates market value. Securities and
assets for which market quotations are not readily available are valued at fair
value as determined in good faith by or under the direction of the Board of
Directors of the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked to market to reflect the current market value of the
option written. When a security is purchased or sold through an exercise of an
option, the related premium paid (or received) is added to (or deducted from)
the basis of the security acquired or deducted from (or added to) the proceeds
of the security sold. When an option expires (or the Fund enters into a closing
transaction), the Fund realizes a gain or loss on the option to the extent of
the premiums received or paid (or gain or loss to the extent the cost of the
closing transaction exceeds the premium paid or received).

  Written and purchased options are non-income producing investments.

- - Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees 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 Fund as unrealized gains or losses.
When the contract is closed, the Fund records a

                                       211
<PAGE>   213

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

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.

- - Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (f) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates. Distributions in excess of realized
capital gains are due primarily to differing tax treatments for post-October
losses.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $3,437 have been reclassified between undistributed net
investment income and accumulated net realized capital losses and $225 has been
reclassified between paid-in capital in excess of par and undistributed net
investment income. These reclassifications have no effect on net assets or net
asset value per share.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--PRIME BOND FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

FISCAL YEAR IN REVIEW

  For the 12 months ended December 31, 1999, the Fund's Class A Shares had a
total return of -2.35% compared to a total return of -1.89% for the unmanaged
Merrill Lynch Corporate Master Index and an average total return of -1.96% for
the Lipper Corporate A Rated Annuity Group. Overall, Fund performance benefited
from the Fund's 35% allocation to corporate bonds rated BBB/Baa by the major
rating agencies. However, Fund performance was negatively impacted as a result
of its holdings in two bonds, Frontier Corp. and Flowers Industries Inc. With
respect to Frontier Corp., this company was acquired by Global Crossing in 1999.
Although well-known, Global Crossing had a non-investment grade rating on their
bonds, which caused Frontier's investment-grade rated bonds to suffer spread
widening and price erosion. Flowers Industries, which makes Mrs. Smith's pies
and Keebler cookies, was hurt by manufacturing problems that arose when the
company implemented a new automation process. As a result, market share suffered
and profitability was negatively impacted. In both cases, we believe that these
bonds can recover during the coming year since both companies possess strong
business models.

THE ENVIRONMENT

  During the six-month period ended December 31, 1999, the fixed-income markets
remained very volatile as interest rates continued to trend higher. Investor
expectations that the Federal Reserve Board would move to tighten monetary
policy in the face of strong economic growth around the world, led to the rise
in Treasury yields. Although inflationary pressures were relatively well
contained, the Federal Reserve Board raised interest rates 0.75% during the
period in response to significant improvements in productivity, the growth of
gross domestic product (GDP) and the correlating effect it has had on the labor
market. This shift in monetary policy served to reverse the accommodative policy
that was implemented during the financial crises of 1998.

  Despite second quarter GDP growth of 1.8%, the US economy continued to move
forward at a strong pace, as highlighted by the strong rebound in third quarter
GDP to 5.7%. Consumer spending continued to lead the way, although recent
reports related to housing and auto purchases are beginning to show the effect
of higher interest rates. Consumers continued to benefit from low unemployment
rates and the wealth effect generated from a strong stock market, although much
of the gains have been limited to only a few sectors with performance in many of
the established industries lagging. Overseas, Asian countries at the heart of
the crises in 1998 continue to recover. This global recovery has, at times, led
to fears of a rekindling of inflation. Commodities, such as copper, plywood and
other building materials, and chemicals gained in price. More importantly, the
price of oil surged, spurred on mainly by an agreement by the Organization of
Petroleum Exporting Countries to limit production, but also on expectations of
increased demand by recovering economies. Wage inflation continued to be of
concern given the level of unemployment that the economy has achieved. However,
inflation as measured by both the producer price index and consumer price index
remains well within acceptable levels, for the most part, with productivity
measurements still extremely favorable. Beyond the gain in interest rates, the
market environment was still being influenced by a flight from quality. This is
in stark reversal of the flight to quality trades we saw in the third quarter of
1998.

  On the corporate bond front, by mid-year underwriting activity increased
significantly as issuers sought to get their funding programs in before the
final quarter of 1999. Corporate yield spreads relative to US Treasury
securities widened across all sectors during the period from May through
September. With respect to sector performance, Yankee or foreign issues
outperformed the domestic issues, and bonds rated BBB outperformed those rated A
or better on both a price and total return basis. However, since late September,
corporate yield spreads tightened following a sooner-than-expected drop in new
underwriting activity. Furthermore, investors began to pump new money into the
investment-grade sector, given the higher yields and strong relative value
attributes.

PORTFOLIO MATTERS

  The Fund's investment strategy remained somewhat conservative given the
outlook for higher interest rates and wider yield spreads. From a duration
perspective, we continued to maintain a duration that was modestly short (0.15
year-0.25 year) as compared to the benchmark Merrill Lynch Corporate Master
Index. Initially, it was our strategy to bring

                                       215
<PAGE>   217
- --------------------------------------------------------------------------------

duration closer to the Index when yields would climb closer to the high end of
the expected range. By early August, we began to reallocate a portion of assets
away from securities with a spread to US Treasury issues and into cash and
Treasury securities, in preparation for year-end liquidity needs. Initially, we
shifted approximately 10% of the Fund into this sector, although improved
fundamentals within the investment-grade market prompted a partial reallocation
back into high-grade, large benchmark issues. By period-end, we reduced the
Fund's allocation to cash and Treasury issues down to the 5% area.

  With respect to the Fund's corporate holdings, we remained committed to the
bigger, more liquid issues as well as those issues with higher coupons. As part
of our liquidity strategy, we attempted to consolidate industry holdings into
the benchmark issues. Although this comes at modest yield concessions, we
believed this was the prudent course of action given the uncertainty surrounding
the Year 2000. Given the increased supply and higher interest rate environment,
many of the new corporate transactions were done at larger-than-anticipated
yield spread concessions in order to attract investors. In view of the temporary
supply factor and wider spreads, we believed corporate bonds possessed some very
attractive long-term relative value attributes. Accordingly, during the final
quarter of 1999, we continued to redirect excess assets back to corporate bonds
in an effort to seek to enhance current income.

  With respect to security-specific issues, we held an overweighted position in
electric utilities, finance companies, cable and media entities, retailers,
energy-related issuers, airlines and defense contractors and information
technology entities for most of the period. During the latter part of the
period, we began to reduce the Fund's holdings in defense issues, high-end
retailers, airlines and real estate investment trusts. On the other hand, we
concentrated on adding to positions in domestic banks, supermarkets, railroads
and metals/mining companies. We also continued to underweight property and
casualty insurers and health care companies.

INVESTMENT OUTLOOK

  Going forward, we have formulated an investment strategy based on our belief
that the long-term trend will be toward lower interest rates and a flatter yield
curve as the economy slows during the second half of 2000. With respect to
corporate bonds, we are looking for yield spread relationships to exhibit
further improvement as we proceed through the first quarter of 2000. However, in
the near term, the Treasury market will remain under pressure as the Federal
Reserve Board is likely to move short-term interest rates higher in the coming
months.

IN CONCLUSION

  We appreciate your investment in Prime Bond Fund of Merrill Lynch Variable
Series Funds, Inc., and we look forward to sharing our investment outlook and
strategies with you in our next report to shareholders.

Sincerely,

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--PRIME BOND FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A Shares
and Class B Shares have equal voting, dividend, liquidation and other rights,
except that only shares of the respective classes are entitled to vote on
matters concerning only that class and Class B Shares bear certain expenses
related to the distribution of such shares. Prime Bond Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Short-term securities are valued at amortized cost, which approximates
market value. Securities and assets for which market quotations are not readily
available are valued at fair value as determined in good faith by or under the
direction of the Board of Directors of the Company.

  (b) Repurchase agreements--The Fund invests in US Government securities
pursuant to repurchase agreements. Under such agreements, the counterparty
agrees to repurchase the security at a mutually agreed upon time and price. The
Fund takes possession of the underlying securities, marks to market such
securities and, if necessary, receives additional securities daily to ensure
that the contract is fully collateralized. If the counterparty defaults and the
fair value of the collateral declines, liquidation of the collateral by the Fund
may be delayed or limited.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income (including amortization of premium and discount) is recognized
on the accrual basis. Realized gains and losses on security transactions are
determined on the identified cost basis.

  (e) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend date.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and portfolios
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the funds. For such services, the Fund
pays a monthly fee based upon the aggregate daily value of net assets of the
Fund and the Company's High Current Income Fund at the following annual rates:
 .50% of such average daily net assets not exceeding $250 million; .45% of such
average daily net assets in excess of $250 million but not more than $500
million; .40% of such average daily net assets in excess of $500 million but not
more than $750 million; and .35% of such average daily net assets in excess of
$750 million. For the year ended December 31, 1999, the aggregate average daily
net assets of the Fund and the Company's High Current Income Fund was
approximately $1,084,230,000.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that

                                       227
<PAGE>   229

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

limits the operating expenses paid by the Fund, exclusive of any distribution
fees imposed on Class B Shares, to 1.25% of its average daily net assets. Any
such expenses in excess of 1.25% of average daily net assets will be reimbursed
to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  For the year ended December 31, 1999, the Fund paid Merrill Lynch Pricing
Service, an affiliate of Merrill Lynch, Pierce, Fenner & Smith, Incorporated,
$5,344 for providing security price quotations to compute the net asset value of
the Fund.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.

  Accounting services are provided to the Fund by MLAM at cost.
  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--QUALITY EQUITY FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  For the year ended December 31, 1999, the Fund's Class A Shares had a total
return of +31.43%. This compares to the +21.04% total return for the unmanaged
Standard & Poor's 500 (S&P 500) Index for the same 12-month period.

  During 1999, the US equity market was characterized by outperformance of a
narrow group of common stocks, particularly technology-related sectors. For the
12 months ended December 31, 1999, the Fund benefited by having the largest
concentration of its US equity assets in the technology group. In the foreign
equity sector, we focused on the shares of companies in "new economy" sectors,
such as telecommunications equipment and technology. This strategy proved
rewarding, given the similar outperformance of equities in these sectors
relative to markets outside of the United States during 1999.

PORTFOLIO MATTERS

  As of December 31, 1999, the Fund's asset allocation was: US equities, 73% of
net assets; foreign equities, 22%; and cash reserves, 5%.

  We increased the foreign equity sector from 11% of net assets to 22% during
the six months ended December 31, 1999. Our strategy was to continue to focus on
the shares of companies that we believed offered the best potential to
outperform the US equity market as reflected by the benchmark S&P 500 Index.
Technology continued to account for the major portion of foreign equity assets.
Positions included Nortel Networks Corporation, Nokia Oyj, STMicro-electronics
NV, Telefonaktiebolaget LM Ericsson, Flextronics International Ltd. and Sony
Corporation.

  We reduced the Fund's position in US equities from 91% of net assets to 73%.
Technology remained the largest single group represented in the portfolio,
accounting for nearly one-third of the portfolio's US equity assets. This
commitment reflects our continuing emphasis on the shares of companies where we
believe a consistent and above-average rate of earnings growth has the potential
to be extended over the next several years and where valuations appear
reasonable relative to earnings growth potential. Consistent with this focus is
the Fund's significant commitments in the consumer staples, communications
services, financial and health care sectors.

IN CONCLUSION

  We appreciate your investment in Quality Equity Fund of Merrill Lynch Variable
Series Funds, Inc., and we look forward to sharing our investment outlook and
strategies with you in our next report to shareholders.

Sincerely,

/s/ Terry K. Glenn

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--QUALITY EQUITY FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Quality Equity Fund (the "Fund") is classified
as "diversified," as defined in the Investment Company Act of 1940. The Fund's
financial statements are prepared in accordance with generally accepted
accounting principles, which may require the use of management accruals and
estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-the-counter
market, valuation is the last asked price. Short-term securities are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Directors of
the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts.

- - Options--The Fund may write covered call options.  When the Fund writes an
option, an amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option written. When
a security is purchased or sold through an exercise of an option, the related
premium received is added to (or deducted from) the basis of the security
acquired or deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums received (or
gain or loss to the extent the cost of the closing transaction exceeds the
premium received).

  Written options are non-income producing investments.

  (c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets and liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

  (d) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.

  (e) Security transactions and investment income--Security transactions are
recorded on

                                       239
<PAGE>   241

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

the dates the transactions are entered into (the trade dates). Dividend income
is recorded on the ex-dividend dates. Dividends from foreign securities where
the ex-dividend date may have passed are subsequently recorded when the Fund has
determined the ex-dividend date. Interest income (including amortization of
premium and discount) is recognized on the accrual basis. Realized gains and
losses on security transactions are determined on the identified cost basis.

  (f) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates. Distributions in excess of investment
income are due primarily to differing tax treatments for foreign currency
transactions.

  (g) Reclassification--Generally accepted accounting principles require that
certain components of net assets be adjusted to reflect permanent differences
between financial and tax reporting. Accordingly, current year's permanent
book/tax differences of $570,270 have been reclassified between undistributed
net realized capital gains and undistributed net investment income. These
reclassifications have no effect on net assets or net asset value per share.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--QUALITY EQUITY FUND
INDEPENDENT AUDITORS' REPORT

THE BOARD OF DIRECTORS AND SHAREHOLDERS,
QUALITY EQUITY FUND OF
MERRILL LYNCH VARIABLE SERIES FUNDS, INC.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Quality Equity Fund of Merrill Lynch Variable
Series Funds, Inc. as of December 31, 1999, the related statements of operations
for the year then ended and changes in net assets for each of the years in the
two-year period then ended, and the financial highlights for each of the years
in the five-year period then ended. These financial statements and the financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and the financial
highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at December
31, 1999 by correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Quality Equity Fund
of Merrill Lynch Variable Series Funds, Inc. as of December 31, 1999, the

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--RESERVE ASSETS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  For the year ended December 31, 1999, the Reserve Assets Fund's Class A Shares
had a net annualized yield of 4.76%. For the six-month period ended December 31,
1999, the Fund's Class A Shares had a net annualized yield of 4.96%. The Fund's
Class A Shares' 7-day yield as of December 31, 1999 was 5.36%. The average
portfolio maturity was 55 days at December 31, 1999, compared to 71 days at June
30, 1999.

THE ENVIRONMENT

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the two-
year Treasury note yield hit a two-year high over concerns of the continued
strength of the economy and potential future action by the Federal Reserve
Board. Against the background of still higher interest rates, we positioned the
Fund more conservatively. We expect to continue to concentrate new investments
in the one-month and three-month areas as we wait for a clearer economic picture
to emerge.

  The Fund's composition at the end of December and as of our last report to
shareholders is detailed below:

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--RESERVE ASSETS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Reserve Assets Fund (the "Fund") is classified
as "diversified," as defined in the Investment Company Act of 1940. The Fund's
financial statements are prepared in accordance with generally accepted
accounting principles, which may require the use of management accruals and
estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities with remaining maturities
of greater than sixty days, for which market quotations are readily available,
are valued at market value. As securities transition from sixty-one to sixty
days to maturity, the difference between the valuation existing on the
sixty-first day before maturity and maturity value is amortized on a
straight-line basis to maturity. Securities maturing sixty days or less from
their date of acquisition are valued at amortized cost, which approximates
market value. For the purposes of valuation, the maturity of a variable rate
security is deemed to be the next coupon date on which the interest rate is to
be adjusted. Other investments for which market quotations are not available are
valued at their fair value as determined in good faith by or under the direction
of the Company's Board of Directors.

  (b) Repurchase agreements--The Fund invests in US Government securities
pursuant to repurchase agreements. Under such agreements, the counterparty
agrees to repurchase the security at a mutually agreed upon time and price. The
Fund takes possession of the underlying securities, marks to market such
securities and, if necessary, receives additions to such securities daily to
ensure that the contract is fully collateralized. If the counterparty defaults
and the fair value of the collateral declines, liquidation of the collateral by
the Fund may be delayed or limited.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute all of its taxable income to its shareholders. Therefore, no Federal
income tax provision is required.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income (including amortization of discount) is recognized on the
accrual basis. Realized gains and losses on security transactions are determined
on the identified cost basis.

  (e) Dividends and distributions--The Fund declares dividends daily and
reinvests monthly such dividends (net of non-resident alien tax and back-up
withholding tax) in additional shares of beneficial interest at net asset value.
Dividends and distributions are declared from the total of net investment income
and net realized gain or loss on investments.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which
is the limited partner.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the following annual rates: .500% of the Fund's average daily net assets not
exceeding $500 million; .425% of average daily net assets in excess of $500
million but not exceeding $750 million; .375% of average daily net assets in
excess of $750 million but not exceeding $1 billion; .350% of average daily net
assets in excess of $1 billion but not exceeding $1.5 billion; .325% of average
daily net assets in excess of $1.5 billion but not exceeding $2 billion; .300%
of average daily net assets in excess of $2 billion but not exceeding $2.5
billion and .275% of average daily net assets in excess of $2.5 billion.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement

                                       250
<PAGE>   252

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

which limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.

  Financial Data Services, Inc. ("FDS"), a wholly-owned subsidiary of ML & Co.,
is the Company's transfer agent.

  Merrill Lynch Funds Distributor, a division of Princeton Funds Distributor,
Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.,
is the Fund's distributor.

  Accounting services are provided to the Fund by MLAM at cost.

  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

3. CAPITAL SHARE TRANSACTIONS:

The number of shares sold, reinvested and redeemed during the periods
corresponds to the amounts included in the Statements of Changes in Net Assets
for net proceeds from sale of shares, value of shares reinvested and cost of
shares redeemed, respectively, since shares are recorded at $1.00 per share.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--SPECIAL VALUE FOCUS FUND
DECEMBER 31, 1999--ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  The US economy finished 1999 with strong growth, low inflation, accelerating
productivity, strong earnings and rising real wages. At its meeting on November
16, 1999, the Federal Reserve Board announced its move to tighten interest rates
by 25 basis points (0.25%), essentially putting short-term interest rates back
to where they were before the three quarter-point cuts that were made in the
fall of 1998. Monetary policy was kept steady at the central bank's last meeting
in 1999 on December 21 over Year 2000 concerns, but indications point to further
tightening in early 2000. (The Federal Reserve Board did raise the Federal Funds
rate by 0.25% on February 2, 2000.)

  US stock markets rebounded in October and advanced on a technology-driven
rally in November. Significant strength in small-capitalization stocks also
emerged in November, particularly in the small cap growth sector. Overall, US
stock markets ended the year at new highs. In the fixed-income area, the 30-year
Treasury bond yield hit a two-year high over concerns of the continued strength
of the economy and potential future action by the Federal Reserve Board.

FISCAL YEAR IN REVIEW

  For the 12 months ended December 31, 1999, Special Value Focus Fund sharply
outperformed the unmanaged Russell 2000 Index. Total returns for the Fund's
Class A and Class B Shares were +34.15% and +33.99%, respectively. These returns
compare to the total return of +21.26% for the Russell 2000 Index for the same
period. Positive sector positioning and strong stock selection combined to
produce favorable investment results for the year.

  Individual stocks that most benefited the Fund's investment results for the
year included APAC Customer Services Inc., VISX, Incorporated and DSP
Communications, Inc. Shares of APAC Customer Services appreciated sharply in the
final months of the year on improved fundamentals in the teleservices business
and the launch of an Internet-based customer service initiative. Shares of VISX,
Incorporated, a provider of systems for laser vision correction, also
contributed favorably to investment results. VISX shares rallied on market share
advances and strong industry growth in laser vision correction procedures. We
dramatically reduced the Fund's position in VISX as the stock reached our
valuation objective and concerns surfaced with the entry of a new competitor
into the US market. DSP Communications, Inc., a designer of chipsets used
primarily in wireless devices, also benefited the Fund's investment results.
Demand for DSP's wireless chipsets surged and the company was acquired by Intel
Corp. at a substantial premium.

  During the fiscal year, the Fund's investment results were hindered by an
investment in shares of CHS Electronics, Inc., an international distributor of
microcomputers and related products. We eliminated the Fund's entire position in
CHS Electronics after the discovery of accounting irregularities at the company.
We reinvested the proceeds into distribution stocks where we had greater
confidence in the near-term earnings outlook.

  Within the Russell 2000 Index, the technology, utility and producer durables
sectors posted sharp gains for the year, while the consumer staples, financial
services and transportation sectors declined. On balance, sector positioning had
a positive effect on the Fund's investment results for the fiscal year. The
portfolio was overweighted in the technology sector, which outperformed the
benchmark index. Relative to the Russell 2000 Index, the Fund's underweighting
in financial services and consumer staples stocks further benefited investment
results. Approximately one-third of the Fund's total return in excess of the
Russell 2000 Index was the result of sector positioning. The remaining
two-thirds was attributable to positive stock selection.

stocks that had reached our internal price objectives, and re-deployed the
proceeds in stocks trading near the low end of their historical valuation
ranges. Notable changes to the Fund's investment positioning included an
increase in consumer discretionary stocks. We added a mix of retail, educational
services, customer relationship management and temporary staffing stocks to the
portfolio. We made minor reductions in the weight of the energy, materials

  Despite the strong recent performance of the Russell 2000 Index, we continued
to find many attractive small-capitalization investment opportunities. The
returns of the past year are remarkable because performance gains were

more heavily concentrated in high growth companies. Many small-capitalization
companies with solid earnings and moderate growth prospects are still trading at
extremely attractive valuation levels.

IN CONCLUSION

  We thank you for your continued investment in Special Value Focus Fund of
Merrill Lynch Variable Series Funds, Inc., and we look forward to reviewing our

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--SPECIAL VALUE FOCUS FUND
NOTES TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

1. SIGNIFICANT ACCOUNTING POLICIES:

Merrill Lynch Variable Series Funds, Inc. (the "Company") is an open-end
management investment company that is comprised of 18 separate funds. Each fund
offers two classes of shares to the Merrill Lynch Life Insurance Company, ML
Life Insurance Company of New York (indirect wholly-owned subsidiaries of
Merrill Lynch & Co., Inc. ("ML & Co.")), and other insurance companies, that are
not affiliated with ML & Co., for their separate accounts to fund benefits under
certain variable annuity and variable life insurance contracts. Class A and
Class B Shares have equal voting, dividend, liquidation and other rights, except
that only shares of the respective classes are entitled to vote on matters
concerning only that class and Class B Shares bear certain expenses related to
the distribution of such shares. Special Value Focus Fund (the "Fund") is
classified as "diversified," as defined in the Investment Company Act of 1940.
The Fund's financial statements are prepared in accordance with generally
accepted accounting principles, which may require the use of management accruals
and estimates. The following is a summary of significant accounting policies
followed by the Fund.

  (a) Valuation of investments--Portfolio securities that are traded on stock
exchanges are valued at the last sale price as of the close of business on the
day the securities are being valued, or lacking any sales, at the closing bid
price. Securities traded in the over-the-counter market are valued at the last
available bid price prior to the time of valuation. Portfolio securities that
are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market, and it is
expected that for debt securities this ordinarily will be the over-the-counter
market. Options written are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-the-counter
market, valuation is the last asked price. Short-term securities are valued at
amortized cost, which approximates market value. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of Directors of
the Company.

  (b) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity and debt markets. Losses may arise due to
changes in the value of the contract or if the counterparty does not perform
under the contract.

- - Options--The Fund may write covered call options.  When the Fund writes an
option, an amount equal to the premium received by the Fund is reflected as an
asset and an equivalent liability. The amount of the liability is subsequently
marked to market to reflect the current market value of the option written. When
a security is purchased or sold through an exercise of an option, the related
premium received is added to (or deducted from) the basis of the security
acquired or deducted from (or added to) the proceeds of the security sold. When
an option expires (or the Fund enters into a closing transaction), the Fund
realizes a gain or loss on the option to the extent of the premiums received (or
gain or loss to the extent the cost of the closing transaction exceeds the
premium received).

  Written options are non-income producing investments.

  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends, and
capital gains at various rates.

  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Interest income (including
amortization of premium and discount) is recognized on the accrual basis.
Realized gains and losses on security transactions are determined on the
identified cost basis.

  (e) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates. Distributions in excess of net investment
income are due primarily to differing tax treatments for post-October losses.

2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:

The Company has entered into an Investment Advisory Agreement with Merrill Lynch
Asset Management, L.P. ("MLAM"). The general partner of MLAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which

Agreement and Distribution Plan with Merrill Lynch Funds Distributor ("MLFD" or
the "Distributor"), a division of Princeton Funds Distributor, Inc. ("PFD"),
which is a wholly-owned subsidiary of Merrill Lynch Group, Inc.

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of .75% of the average daily value of the Fund's net assets.

  Pursuant to the Distribution Plan adopted by the Company, in accordance with
Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the
Distributor an ongoing distribution fee each month at the annual rate of .15% of
the average daily value of the Fund's Class B net assets.
  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement that limits the operating expenses paid by the Fund, exclusive of any
distribution fees imposed on Class B Shares, to 1.25% of its average daily net
assets. Any such expenses in excess of 1.25% of average daily net assets will be
reimbursed to the Fund by MLAM which, in turn, will be reimbursed by MLLA.
  For the year ended December 31, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a subsidiary of ML & Co., earned $132,225 in commissions on the
execution of portfolio security transactions.

  Certain officers and/or directors of the Company are officers and/or directors
of MLAM, PSI, FDS, PFD, and/or ML & Co.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--SPECIAL VALUE FOCUS FUND
INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

THE BOARD OF DIRECTORS AND SHAREHOLDERS,
SPECIAL VALUE FOCUS FUND OF
MERRILL LYNCH VARIABLE SERIES FUNDS, INC.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Special Value Focus Fund of Merrill Lynch
Variable Series Funds, Inc. as of December 31, 1999, the related statements of
operations for the year then ended and changes in net assets for each of the
years in the two-year period then ended, and the financial highlights for each
of the years in the five-year period then ended. These financial statements and
the financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned at December
31, 1999 by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of Special Value Focus
Fund of Merrill Lynch Variable Series Funds, Inc. as of December 31, 1999, the
results of its operations, the changes in its net assets, and the financial
highlights for the respective stated periods in conformity with generally
accepted accounting principles.
