JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. Meanwhile, Japan reported its first quarter of
positive economic growth in more than one year. There were growing signs of
improvement in some emerging economies (most notably South Korea and Mexico),
although concerns remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

PORTFOLIO MATTERS

As of June 30, 1999, the Fund's asset allocation was: US bonds, 44% of net
assets; US stocks, 52%; and cash reserves, 4%.

  We reduced the Fund's allocation to US equities from 55% of net assets as of
December 31, 1998 to 52% as of June 30, 1999. We continued to believe that
investors will favor the shares of companies that offer a high degree of
earnings visibility in a steady growth/low inflationary economy. On this basis,
technology remained the largest single group represented among our US equity
commitments. Positions established in the technology sector during the past
three months included Sun Microsystems, Inc., Xerox Corporation and Siebel
Systems, Inc. Consumer staples, including healthcare and financial services,
also continued to account for a significant portion of US equity assets.

  We increased the Fund's US bond commitment from 40% of net assets to 44%
during the six months ended June 30, 1999. We also increased the average
duration from 5.4 years to 7.0 years. Contrary to our earlier expectations, the
strength of the US economy persisted during the second quarter of 1999. However,
we expect the rise in intermediate-term and longer-term interest rates which has
taken place in recent months to gradually slow the rate of US economic growth in
coming quarters. In our view, any resultant reduction of inflationary
expectations would be likely to be supportive of a decline in US interest rates
during the second half of 1999.

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,

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

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
to the operations of the funds. For such services, the Fund pays a monthly fee
at the annual rate of 0.55% 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.--BASIC VALUE FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

During the six-month period ended June 30, 1999, the US stock market gained
11.7% as measured by the unmanaged Standard & Poor's 500 Index (S&P 500). This
rise reflected a continuation of robust economic growth coupled with low
inflation. As 1999 progressed, investors set their sights on the outlook for
improvement in the world economies. An interest rate cut in Europe fueled hopes
for recovery in global economies, and Japan experienced gross domestic product
growth in the first quarter. Moreover, oil prices surged in response to the
Organization of Petroleum Exporting Countries' (OPEC) agreement to sharply
reduce supply.

  Against this backdrop, for the six-month period ended June 30, 1999, Basic
Value Focus Fund's Class A and Class B Shares had total returns of +22.17% and
+22.11%, respectively, nearly twice the return of the S&P 500. The Fund's
disciplined value approach to investing rewarded shareholders during the
six-month period with returns exceeding most major market indexes as well as the
Lipper Growth and Income Index and a peer group of funds that employ a similar
philosophy. Our value-driven, bottom-up approach continued to dictate our stock
selection activities during the period. We remain confident that the Fund is
positioned to benefit from our strategy as we continue to identify what we
believe to be quality companies at bargain prices.

  During the six-month period ended June 30, 1999, our stock selection process
led to overweight positions in technology, energy, capital goods and basic
materials sectors. This positioning was largely responsible for the impressive
gain posted by the Fund at June 30, 1999. Stocks in these sectors responded
favorably to the notion of global economic recovery given that their earnings
are closely linked with economic activity. Long-term shareholders may recall
that when oil prices were sliding toward $11 per barrel last year, we sizably
increased our holdings based on our belief that OPEC would take a disciplined
approach to production. That position rewarded shareholders well as oil
rebounded to $19 per barrel and holdings of Unocal Corporation, Diamond Offshore
Drilling, Inc. and Halliburton Company all gained more than 30%. Significant
gains were also achieved by our investments in Royal Dutch Petroleum Company,
which rose almost 20%, and Rowan Companies, Inc., which nearly doubled during
the first six months of 1999. Investors may further recall that technology
stocks were also an area of increased emphasis last year when they suffered from
a slowdown in demand from Asia and overcapacity. With an improved outlook for
the Asian economies and in some cases company-specific improvements, holdings of
Hewlett-Packard Company (+47%), International Business Machines Corporation
(+38%), Silicon Graphics, Inc. (+30%), Integrated Device Technology, Inc.
(+81%), Novell, Inc. (+47%) and Motorola, Inc. (+55%) all proved to be
profitable investments for shareholders. Finally, the bottoming in Asian
economies during the period translated into strong stock price performance for
low-valuation cyclical stocks whose earnings are closely tied to economic
cycles. Chemical producers E.I. du Pont de Nemours and Company and Hercules
Incorporated gained 21% and 44%, respectively, while paper producer Champion
International Corporation gained 25% during the six-month period. Copper
producer ASARCO Incorporated also rebounded during the period, generating a 24%
return for shareholders. Capital goods stocks The Boeing Company (+37%), Eaton
Corporation (+31%), Caterpillar, Inc. (+32%) and Deere & Company (+25%) also
benefited from prospects for earnings acceleration.

  One notable area of weakness during the six-month period was the financial
sector, including banks and insurance companies. The operating environment for
insurance companies in particular has been difficult given continued
overcapacity, which has put downward pressure on premiums. This has been an area
of increased focus for the Fund during the past six months given the depressed
stock prices and valuation parameters of many seemingly high-quality insurance
companies. We added several new companies to the Fund including Ace Limited, The
Allstate Corporation, Hartford Financial Services Group, Inc. (which was
subsequently sold within the six-month period) and The St. Paul Companies, Inc.
We remain committed to these companies that we believe to be undervalued, which
are growing through acquisitions and cost cutting programs. Another area of
emphasis during the period was defense. Specifically, we added TRW Inc.,
Northrup Grumman Corporation and Lockheed Martin Corporation. With a US budget
surplus and higher defense spending by the US Government, we believe these
out-of-favor stocks may begin to show upward earnings momentum in the future.

  During the six-month period ended June 30, 1999, we eliminated several
positions from the portfolio as improved investor enthusiasm led to extended
valuation levels and solid profits for shareholders. The most notable examples
were

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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

("PSI"), an indirect, wholly-owned subsidiary of ML & Co., which is the limited
partner. The 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 0.60% 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 0.15% of the average

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--CAPITAL FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

INVESTMENT ENVIRONMENT

The US stock market continued its powerful advance during the six months ended
June 30, 1999 with the broad market averages reaching new highs at the end of
June. In the early months of the year, accelerating financial market liquidity,
continued respectable levels of domestic economic activity and a growing belief
that the worst of the emerging market challenges had passed, propelled the
market higher.

  With the money supply growing greater than 11% on an annualized basis while
the economy experienced much slower nominal growth, these excess fund flows were
redirected to financial assets.

  Real consumer spending remained robust, supporting continued strong housing
and auto sales and solid fourth quarter economic growth. Furthermore, some
evidence of improvement in economic conditions emerged in select developing
countries like South Korea, lessening the threat from this volatile region.
Meanwhile, inflationary pressures remained benign with the implicit price
deflator rising at a mere 0.8% annual rate in the fourth quarter, the lowest
increase since 1959. Finally, strong fourth quarter earnings reports from many
prominent large-capitalization companies helped drive the stock market higher.
However, by spring concerns over the sustained rapid pace of economic growth and
its implications for higher inflation produced rising interest rates and falling
stock prices. The continued strength in the consumer sector of the US economy
was augmented by improved conditions in the industrial sector, led by renewed
export market opportunities. This broader growth platform, combined with the
rapid increase in energy prices during 1999, engendered fears of accelerating
inflation and encouraged the Federal Reserve Board to adopt a tightening
monetary policy bias at its Federal Open Market Committee meeting, driving long-
term interest rates to their highest levels in over a year.

  Since rising interest rates typically compress equity valuations, stock prices
declined accordingly, particularly in those market sectors most sensitive to
interest rate movements such as financials, technology and growth. In early
summer, positive Federal Reserve Board actions, further evidence of resurgent
global growth and rising expectations for second-quarter profits renewed the
market's advance and propelled the broad market averages to record high levels.
The Federal Reserve Board's decision to increase the Federal Funds rate by a
mere 25 basis points (0.25%) and to change its bias regarding its future course
of action from tightening to neutral suggested that there would not be any
further short-term interest rate hikes for the balance of 1999. This favorable
confluence of events drove the unmanaged Standard & Poor's 500 (S&P 500) Index
to a +12.38% total return for the six-month period ended June 30, 1999. In
contrast, fixed-income investors, fearing the inflationary implications of
strong economic growth, drove long-term interest rates above the 6% level,
resulting in a -1.50% total return for the unmanaged Merrill Lynch Domestic Bond
Master Index for the six-month period ended June 30, 1999. Cash equivalents
provided a +2.24% total return for the same period, as measured by the Merrill
Lynch 91-day Treasury Bill Index.

PORTFOLIO MATTERS

While these favorable developments could suggest a positive near-term outlook
for equities, we remain concerned about the market's ability to provide
significant appreciation from current levels. Robust fundamental conditions have
driven overall stock market valuations to record high levels, which we believe
could constrain the market's further advance. While market valuations could
certainly expand further, we believe it is not appropriate to base investment
decisions on such a view.

  On the other hand, bonds currently appear to offer good value with
inflation-adjusted interest rates at historically high levels and the
possibility that inflationary pressures may moderate. We believe the Federal
Reserve Board's proactive posture could slow economic growth and keep inflation
in check, potentially offering attractive total return opportunities in the
fixed-income market. As a result, we maintained a significant weighting in
fixed-income securities, with 64.2% of net assets invested in equities, 32.0% in
fixed-income securities and 3.8% in cash equivalents at June 30, 1999.

  Within the equity component of the Fund, we continued to adjust our holdings
to seek to enhance quality and better control risk during the period. We added
nine new investments, increased positions in 26 holdings, reduced positions in
10 holdings, and eliminated eight stocks from the portfolio. Notable among the
new positions was Mellon Bank Corporation, the Pittsburgh-based regional banking
concern, which has dramatically restructured over the last several years and now
generates over 50% of its income from high value, fiduciary businesses

                                       25

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

such as asset management, custody and benefits consulting. The company has moved
into an excess capital position and currently is generating approximately $600
million per year in free capital. All this time, the company enjoys
industry-leading cash returns of 23%-25% on equity with potential opportunities
for further improvement driven by changes in its business mix and capital
structure. Selling at 18 times estimated 1999 cash earnings per share of $4.05
and 16 times estimated 2000 cash earnings of $4.50 per share, we believe this
represents an attractive entry price for the shares of this company. Therefore,
we believe the stock represents a very attractive addition to the Fund.

  We also established a position in Xerox Corporation, the document/copier
company, which has committed to transforming itself from a traditional,
stand-alone black and white copier company to a digital, network, color,
services and solutions company for corporate printing and copying needs. Xerox
currently enjoys a solid financial position with a 36.5% return on equity, a
trend in return on capital that has been improving and interest coverage in
excess of 7 times. Currently selling at 19 times estimated year 2000 earnings
per share of $3.20, we believe Xerox offers an attractive risk/reward profile
and represents an attractive addition to the Fund.

  Despite the stock market's record high levels, we continue to identify and
invest in what we perceive as above-average companies whose stocks sell at
below-average valuation levels. We define an above-average company as one which
maintains a strong competitive position, earns consistently high returns on
capital, is financially sound, generates cash in excess of its internal
reinvestment requirements and is managed by individuals motivated to create
value for shareholders. We define a below-average valuation as one that does not
adequately or accurately reflect what we believe to be the company's underlying
intrinsic value. On average, the stocks held in Capital Focus Fund have up to
now generated comparable returns on shareholders' equity and have had stronger
balance sheets while offering potentially faster earnings growth than the
average company, as measured by the S&P 500. However, these same stocks sell at
an average price to earnings ratio of 25.1 times estimated 1999 earnings per
share versus 32.1 times for the S&P 500, at 5.7 times current book value per
share versus 7.2 times for the S&P 500, and provide an above-average dividend
yield.

  We eliminated our position in YPF, Sociedad Anonima, the Argentine oil
company, which received a $45 per share take-over offer from Repsol, SA, the
Spanish oil company, which had purchased the Argentine government's 20% stake in
YPF earlier in 1998. We believe that this was a fair and full price for YPF, so
we decided to eliminate our position. We also sold our position in Tenet
Healthcare Corporation, the hospital management company. Reimbursement rate
pressures from both the government-sponsored Medicare program and private sector
health maintenance organizations have not abated, leading to what we believe to
be reduced revenue projections and a slower rate of expected earnings growth for
the company. Consequently, Tenet's ability to create shareholder value appears
constrained. We decided these proceeds would be more profitably invested in
alternative investment opportunities.

  Within the fixed-income portion of the portfolio, our decision to maintain a
relatively short average duration of our bonds, ranging from 5.0 years to 5.4
years, proved beneficial as domestic interest rates rose sharply during the
period. We continued to enhance the liquidity of our holdings by substantially
reducing our position in foreign government securities from 11.6% of
fixed-income assets at December 31, 1998 to 3.1% at June 30, 1999. We also
reduced high-yield corporate bonds from 10.7% of fixed-income assets to 8.7%,
while investment-grade corporate bonds increased from 47.5% to 55.7%. US
Government securities also rose from 30.2% of fixed-income assets to 32.5%. As a
result of these transactions, the average quality of our bonds rose from A3/A-
to A2/A, while the average yield to maturity increased by 26 basis points to
7.26%.

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

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. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. 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.

                                       36
<PAGE>   38

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

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 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

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 0.60% of the average daily value of the Fund's net assets.

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

Incorporated ("MLPF&S"), a subsidiary of ML & Co., earned $336 in commissions on
the execution of portfolio security transactions.

Service, and affiliate of MLPF&S, earned $500 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.

DEAR SHAREHOLDER:

During the six-month period ended June 30, 1999, total returns for the Fund's
Class A and Class B Shares were +36.08% and +36.18%, respectively. The unmanaged
Morgan Stanley Capital International Emerging Markets Free Index rose 39.87%
during the same period. Hurting performance were the Fund's overweighted
position in Hungary, which had a return of -8.77%, and underweighted positions
in Russia and South Africa, whose markets had returns of +133.67% and +30.18%,
respectively. Beneficial to performance were the Fund's overweighted positions
in Mexico and Thailand, up 52.31% and 58.26%, respectively, during the period.
(References to securities markets of all countries in this letter to
shareholders correspond to those countries' market weightings in the MSCI
Emerging Markets Free Index and are for the six-month period ended June 30,
1999.)

INVESTMENT OVERVIEW

The recovery in emerging markets continued in the six-month period ended June
30, 1999. Overall, emerging markets enjoyed a broad-based rally driven primarily
by the perception that these economies had seen their worst and were on the road
to recovery. This perception, which we partly share, was supported by evidence
such as rising industrial production in South Korea, a pickup in consumer
spending in Thailand and the recovery in the prices of some commodities such as
pulp and oil.

  Bolstering the case for emerging markets recovery were reflationary efforts in
the major economies of the United States, Japan and the European Union. This was
indicated by the neutral monetary stance of the US Federal Reserve Board through
most of the period, the fiscal stimulus and the possibility of monetization in
Japan, and the decline in interest rates in the European Union. In addition,
investors regained confidence in these markets as countries, such as Brazil,
Malaysia, South Korea and Thailand, were successful in raising capital in the
foreign markets.

  To add balance to this positive assessment of the developing markets, we note
that the evidence of recovery has so far been limited to relatively few
countries. In our view, the necessary structural reforms in countries such as
Indonesia and Brazil are still works in progress. Developing economies and their
emerging markets appear to be recovering, but progress can easily be slowed by
external events.

  These events could include a curtailment of capital flows to the developing
markets if there is a sharp rising trend in US interest rates or a prolonged
decline in the US stock market. Cyclical stocks and the Mexican, Brazilian and
South African stock markets in general could be particularly vulnerable to a
collapse in commodity prices if the European and Japanese economies fail to
reflate. Some Israeli, South Korean and Taiwanese technology shares could be
hurt by a decline in prices of US technology stock prices. Nonetheless, assuming
the investment environments continue to improve, we believe the case for
investing in these countries with a long-term view is very much intact.

  South Korea was one of the best-performing markets during the six months ended
June 30, 1999, rising 77.88%. South Korea is a prime example of an incomplete
restructuring. Although the country has made progress in areas such as
recapitalizing and restructuring the banking sector and increasing transparency
in corporate financial disclosures, little has been achieved in reforming the
giant conglomerates, or chaebols. However, the stock market has rewarded the
South Korean government's stated desire to make the necessary improvements to
the economy.

  Evidence of the seriousness of the South Korean government's intention to
reform will be the deregulation of state companies such as Korea Electric Power
Corporation (KEPCO). KEPCO is the state monopoly for generation and distribution
of electricity. In the past, the company has had to shoulder the burden of
subsidizing the industrial sectors for the sake of economic development. We
believe that the South Korean government is committed to deregulating the
pricing of electricity. South Korea had the largest country weighting in the
Fund, comprising 15.8% of net assets.

  In Thailand, recovery and restructuring continued during the six-month period
ended June 30, 1999. The auctioning of bad loans taken from the finance
companies has been proceeding slowly. The three largest banks--including two
Fund investments, Bangkok Bank Public Company Limited and Thai Farmers Bank
Public Company Limited--appear to be successfully recapitalizing themselves. One
of the largest conglomerates in Thailand, The Siam Cement Public Company
Limited, which is also a holding in the Fund, disposed of subsidiaries and joint
venture stakes in non-core businesses. The stock price of the foreign shares of
Siam Cement quadrupled from its lowest level last year.

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

  Growth prospects for the South African economy improved during the six-month
period ended June 30, 1999. The beginning of a commodity cycle upturn has been
extremely positive for exports of commodities including platinum, diamonds and
coal, which comprise one-third of South Africa's exports. In addition, interest
rates have been declining and may decline further, particularly since the
currency has been relatively stable. Our investments in South Africa comprised
8.5% of net assets.

  Corporate earnings in South Africa were a positive surprise. For example,
Impala Platinum Holdings Limited reported first-half fiscal year earnings per
share up 127%. This was a strong result, despite the flat prices for its metals.
The substantial rise in earnings was driven by the company's cost containment
program, which limited the rise in cash costs to 2.5% for the six-month period,
and by fees from refining other platinum producers' concentrate. In addition to
this, the depreciation of the South African currency during the six-month period
ended June 30, 1999 also benefited the company, since its costs are primarily
rand-based, while its revenues US dollar-based prices for platinum, palladium
and rhodium.

  The two most prominent companies engaged in these restructuring activities are
Anglo American PLC and South African Breweries PLC. Both companies have recently
moved their domiciles to London in an effort to facilitate raising capital and
to potentially lower their costs of capital by diversifying their asset bases.
In anticipation of the changes in domicile, both companies streamlined their
operations, sold off non-core assets, and were developing strategies intended to
drive their future growth prospects, both within and outside of South Africa.

  Restructuring is also an ongoing theme in other countries. In Israel, Koor
Industries Limited continued to enhance its shareholder value through the
disposition of non-core assets in the food and ammunition industries and
consolidation of its positions in the telecommunications industry through
increased holdings in ECI and in the agrochemical industry through increased
ownership of MA Industries.

  In Poland, Elektrim Spolka Akcyjna SA--one of the country's largest industrial
conglomerates and a long-term holding of the Fund--is transforming rapidly under
new management. The company was a post-Soviet era behemoth that inherited a
broad and unrelated array of activities, many of which operated at a loss.
Through divestments and acquisitions, it is focusing on what the Company's
management deems to be businesses that are attractive in Poland and could
increase in value. These are telecommunications services, including wireless and
wired line telephone and cable television, and power, including engineering
services and generation equipment.

  Our equity investments in Brazil comprised 12.1% of the Fund's net assets. As
noted above, fiscal reforms are still pending and their postponement is causing
some concern in the markets. However, there are investments that we believe can
make a positive contribution to the Fund's performance because of their
defensive qualities as well as attractive valuations. One example is the
diversified mining company Companhia Vale do Rio Doce (CVRD). CVRD benefits from
the weaker Brazilian real, as its revenue stream is primarily US dollar-based,
while the majority of its costs are in local currency. As the world's largest
producer of iron ore, the company stands to benefit from improving conditions in
the global steel market. We believe that values such as those in CVRD are
compelling enough to justify taking a long-term position in Brazil,
notwithstanding the near-term market volatility which we expect.

  There has been value in emerging market investments for some time.
Nevertheless, the stock markets declined. We believe that aside from compelling
stock valuations, there are several drivers that could improve the performance
of these stock markets. These include the improving outlook for earnings and
economic growth, the scope for interest rate declines as perceived risk
subsides, and what we believe to be the bottoming out of the global economic
cycle and commodity prices.

+ Non-income producing security.

++ Effective February 16, 1999, the Company's Board of Directors adopted a
   change in valuation for Malaysian securities. The Company will utilize a
   Malaysian exchange rate of 3.80 and record an estimated exit tax on the value
   of any investments made before February 15, 1999, based upon its value as of
   August 31, 1998, in the amount of 30% through March 31, 1999, 20% from April
   1, 1999 through May 31, 1999 and 10% from June 1, 1999 through August 31,
   1999. These changes are due to the capital controls implemented by the
   Malaysian government, which froze the Malaysian ringgit at 3.80 until
   September 1, 1999 and initiated a tax at various rates, as described above,
   on any funds repatriated from Malaysia.

(a) American Depositary Receipts (ADR).

(b) Global Depositary Receipts (GDR).

(c) The security may be offered and sold to "qualified institutional buyers"
    under Rule 144A of the Securities Act of 1933.

(d) Received through a bonus issue from Companhia Vale do Rio Doce. As of June
    30, 1999, the bonds have not commenced trading and the coupon rate has not
    been determined.

(e) Warrants entitle the Fund to purchase a predetermined number of shares of
    common stock and are non-income producing. The purchase price and number of
    shares are subject to adjustment under certain conditions until the
    expiration date.

* US Government Agency Obligations are traded on a discount basis; the interest
  rate shown reflects the discount rate paid at the time of purchase by the
  Fund.

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. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. 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
Funds' 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

                                       55
<PAGE>   57

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

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.

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. The 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 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 0.15%
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 six months ended June 30, 1999, MLAM earned fees of $340,728, of which
$83,901 was voluntarily waived.

  For the six months ended June 30, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a subsidiary of ML & Co., earned $41,821 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.--DOMESTIC MONEY MARKET FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

For the six-month period ended June 30, 1999, Domestic Money Market Fund's net
annualized yield for Class A Shares was 4.52%. The Fund's 7-day yield as of June
30, 1999 was 4.51%. The average portfolio maturity was 73 days at June 30, 1999,
compared to 69 days at December 31, 1998.

THE ENVIRONMENT

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. Meanwhile, Japan reported its first quarter of
positive economic growth in more than a year. Some other emerging economies
(most notably South Korea and Mexico) are also showing some signs of
improvement, although concerns remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

  We continue to concentrate Fund investments in one-month commercial paper,
10-month--12-month medium-term notes and floating rate money market instruments.
We believe that this barbell strategy, coupled with one third of the Fund's
assets in floating rate paper, is appropriate at this time. This strategy was
employed as we consider the possibility of an additional Federal Reserve Board
tightening in the near term but with what we believe to be a low probability of
significant intervention as the year 2000 approaches.

  Longer term, we believe that current yields have sufficiently discounted
negative news. In the near term, we will continue to evaluate economic data as
it becomes available, and we are prepared to shift our strategy, if necessary.

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

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--DOMESTIC MONEY MARKET 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. 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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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 are valued at the most recent bid price or yield
equivalent as obtained from dealers that make markets in such securities. 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 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.

  (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 0.50% 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.

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

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL BOND FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

  There were conflicting signals regarding the future direction of the US
economy during the six-month period ended June 30, 1999. However, based on
concerns that the domestic economy was growing at a pace sufficient to spark
inflation, the Federal Reserve Board shifted its neutral bias toward one of
tightening. On June 30, 1999, the Federal Reserve Board raised interest rates 25
basis points (0.25%).

  Compared to the United States, Canada's growth was less robust, and inflation
showed no signs of accelerating. In fact, Canada's inflation had fallen below
the Bank of Canada's target range. As a result of low inflation and a strong
currency, the Bank of Canada cut its benchmark bank rate by 25 basis points on
March 31 and May 4. Interest rates overall in Canada have risen given their
close correlation to US interest rates. During this period, interest rates rose
by 57 basis points for the ten-year Canadian sovereign bond as compared to a 113
basis point increase for the ten-year US Government bond.

  In Europe, the convergence of the 11 European countries into the European
Monetary Union (EMU) was successfully completed on January 1, but the euro did
not fair very well. With a stagnant Germany, political infighting, low interest
rates and a war in Kosovo, the euro traded down. Germany's Finance Minister
LaFontaine's resignation temporarily inspired the prospects for the euro, but an
aggressive cut in interest rates in April and the protracted war in Kosovo sent
the euro on a downward slide. Interest rates during the period were mostly down
except for the 10-year and 30-year German bonds.

  In non-EMU countries, we continue to see improvement in our UK, Greek, Danish
and Norwegian positions. We are overweight in our holdings in these countries
relative to the unmanaged J.P. Morgan European Bond Index because we believe
these countries are on track for the second wave of convergence into EMU and we
believe their bonds are relatively inexpensive. In the United Kingdom, most of
the improvement in yield has been in Gilts with maturities of less than two
years. This is a direct result of the interest rate cuts by the Bank of England
during this period. On the other hand, ten-year Gilts have risen. The Greek bond
market appreciated across the maturity spectrum. The drachma has remained
somewhat stable relative to the euro. In Denmark, most of the decline has
occurred in sovereign debt with maturities of less than five years. Our new
position during the six-month period was Norway, the world's second-largest
exporter of oil. Norwegian interest rates have fallen, particularly in the under
one-year maturities.

  The yen gained strength as 1999 began, then proceeded to trade lower as
Finance Minister Miyazawa said he would tolerate a lower yen. In addition there
were signs that the Bank of Japan (BOJ) might consider monetizing the debt to
lower interest rates. More fiscal stimulus packages are needed, but they could
impact the debt structure of Japan and lead to a downgrade of the sovereign
debt. This, in turn, could lead to higher interest rates. During the period,
ten-year Japanese government bonds experienced significant volatility.

  In April, the International Monetary Fund (IMF) forecast that Japan's GDP
would contract in 1999, a view at odds with consensus expectations that the
Japanese economy may be bottoming. On June 30, Bank of Japan Governor Hayami
disturbed the Japanese government bond market investors by saying that a quick,
self-sustaining recovery in private demand cannot be expected soon. Our view is
that the Japanese economy may have bottomed, but there are still too many
concerns to allow for a smooth recovery. Until we see signs of slow growth and a
weak yen improving, we will stay underweight in Japan and long US dollars.

PORTFOLIO MATTERS

The six-month period ended June 30, 1999 was characterized by interest rates
worldwide. Therefore, we reduced the overall duration of the Fund. We maintained
our short duration in Japan and moved to a neutral position in the United States
and dollar-bloc countries relative to the unmanaged J.P. Morgan European Bond
Index. We also reduced our duration in EMU countries and increased the duration
of non-EMU countries.

IN CONCLUSION

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

                                       69

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

                                       80
<PAGE>   82
- --------------------------------------------------------------------------------

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.

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 0.60% of the average daily value of the Fund's net assets.

  MLAM and Merrill Lynch Life Agency, Inc. ("MLLA") have entered into an
agreement 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 six months ended June 30, 1999, the Fund paid Merrill Lynch Security
Pricing Service, an affiliate of Merrill Lynch, Pierce, Fenner & Smith,
Incorporated, $63 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.

3. INVESTMENTS:

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL GROWTH FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. Meanwhile, Japan reported its first quarter of
positive economic growth in more than one year. There were growing signs of
improvement in some emerging economies (most notably South Korea and Mexico),
although concerns remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

PORTFOLIO MATTERS

For the six months ended June 30, 1999, the Fund's Class A Shares had a total
return of +5.70%. The total return for the unmanaged Morgan Stanley Capital
International (MSCI) World Stock Index was +8.51% for the same period.

  There were two reasons for the Fund's underperformance. First, we avoided
equity investments in Asia and Latin America because of our concerns about the
duration and breadth of the business and profit recovery in these regions.
During the first half of 1999, several of the major stock markets in Asia,
including the Japanese market, had total investment returns in US dollar terms
well in excess of +20%. Second, starting in April, investors shifted assets from
the relatively more stable earnings growth companies in telecommunications,
banking, insurance, pharmaceuticals and retailing to companies in the energy,
energy services, steel, paper, chemicals, industrial equipment and construction
equipment industries. The Fund had very modest exposure to these areas.

  The Fund's largest industry weightings were in the banking and financial,
telecommunications, insurance and pharmaceuticals industries. In addition,
interest rates on long-term US Treasury securities rose significantly during the
first half of 1999, which may have caused the stock prices and valuations of
many of the Fund's stock holdings in these industries to decline. There appears
to have been a shift of investment funds into many stock market sectors
worldwide ranging from small and medium-sized companies to lower-quality
companies in both developed and emerging equity markets. We view this broadening
of investor focus as a positive development. It may reflect the substantial
increases in financial liquidity by central bankers around the world since
September 1998 when the US Federal Reserve Board started to increase liquidity
and reduce the Federal Funds rate.

  The Fund's best-performing industry sector during the first half of 1999 was
the telecommunications industry, which represented 15.6% of net assets at June
30, 1999. Also, six of the companies among the Fund's largest equity holdings at
June 30, 1999 experienced stock price appreciation during the first half of 1999
in excess of the total investment return of the MSCI World Stock Index. Among
the individual equity holdings in the Fund at mid-year, over 45% of the
individual holdings had stock price appreciation during the first half of 1999
in excess of the total return of the MSCI World Stock Index.

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.

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. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. 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.

                                       95
<PAGE>   97
- --------------------------------------------------------------------------------

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) Deferred organizations 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.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL STRATEGY FOCUS FUND
SEMI-ANNUAL REPORT--JUNE 30, 1999
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. In Japan, there are not yet clear signs that
Japan's economy is improving. There were growing signs of improvement in some
emerging economies (most notably South Korea and Mexico), although concerns
remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

PORTFOLIO MATTERS

As of June 30, 1999, the Fund's asset allocation was: US stocks, 36% of net
assets; foreign stocks, 43%; US bonds, 6%; foreign bonds, 13%; and cash
reserves, 2%.

  During the six months ended June 30, 1999, we enlarged the foreign common
stock sector from 28% of net assets to 43%. The largest portion of the foreign
equity expansion was undertaken by enlarging our commitment to Japanese
equities. This increase reflects our expectation that an increased number of
Japanese corporations would be undertaking significant restructuring that could
lead to improved profitability and earnings over the longer term. Our increased
optimism also reflected indications that monetary policy remained accommodative
and that the Japanese economy was showing signs of bottoming.

  We also enlarged the Fund's commitment to emerging markets, including Brazil
and Asian markets outside of Japan, in response to increased evidence that the
problems associated with the 1997-1998 financial crisis were abating. We
established our commitments in Brazil in response to the improving
post-devaluation outlook. In Asia, we devoted assets to new positions in South
Korea, Singapore and Hong Kong. European equities remained our largest regional
commitment, although we reduced overall representation in recent months. Within
Europe, we maintained significant representation in financial services,
telecommunications services and equipment, and consumer staple goods.

  We slightly reduced the Fund's allocation to US equities from 40% of net
assets to 36% during the six months ended June 30, 1999. We continued to believe
that investors would favor the shares of companies that offered a high degree of
earnings visibility in a steady growth/low inflation economy. On this basis,
technology has remained the largest single group represented among our US equity
commitments. Consumer staples, including healthcare and financial services, also
continued to account for a significant portion of US equity assets.

  In the fixed-income component of the portfolio, we reduced the foreign bond
sector from 19% of net assets to 13% during first half of the six months ended
June 30, 1999. Seemingly attractive risk/reward relationships led us to
establish positions in Japanese and New Zealand bonds early in 1999. However,
during the second half of the period, we eliminated our position in Japanese
bonds following a decline in yields, which reduced potential for additional
appreciation. We also took advantage of the appreciation in the New Zealand
bonds and sold our position. We retained positions in German and UK bonds, where
we believe the risk/reward relationship has remained favorable.

  Finally, we also reduced our US bond commitment from 13% of net assets to 6%
during the six-month period ended June 30, 1999. As a result, we increased the
average duration from 6.0 years to 6.8 years. Strength in the US economy
persisted during the first half of 1999.

IN CONCLUSION

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

                                       98

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

                                       113
<PAGE>   115
- --------------------------------------------------------------------------------

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) Custodian bank--The Fund recorded an amount payable to the Custodian bank
reflecting an overnight overdraft, which resulted from timing differences of
security transaction settlements.

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

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GLOBAL UTILITY FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. In Japan, there are not yet clear signs that
Japan's economy is improving. There were growing signs of improvement in some
emerging economies (most notably South Korea and Mexico), although concerns
remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

INVESTMENT ENVIRONMENT

The consolidation trend in the utility sector is spreading worldwide. Merger and
acquisition activity has increased both domestically and internationally.
Examples include the combination of the UK-based international cellular company,
Vodaphone Group PLC (a Fund holding) and US-based global cellular operator,
AirTouch Communications. The bidding contest between the Italian company
Olivetti SpA and Deutsche Telekom AG for the telecommunications services
provider Telecom Italia SpA, also a Fund holding, is another example. Activity
has not only focused on the fast-growing telecommunications sector but has also
taken place in the electric and water sectors. Scottish Power PLC is in the
process of acquiring the Oregon-based electric utility company PacifiCorp.,
another Fund holding. In approving this transaction and the National Grid
(UK)--New England Electric System purchase, Federal Energy Regulatory Commission
Chairman James Hoecker said it was noteworthy that as US electric power markets
deregulate, individual utilities are sought out by foreign buyers. "These
mergers illustrate," Mr. Hoecker said, "how attractive US utilities are to
foreign capital markets."

  Fund holding Vivendi, a leader in the water business and headquartered in
France, has acquired United States Filter Corporation, which provides water and
wastewater treatment systems, products and services to all customer classes.
Yorkshire Water, of the United Kingdom, just announced its first US acquisition,
the Connecticut-based water treatment service company, Aquarion Co.

  This recent cross border activity in the utility sector is in addition to the
numerous joint ventures and partnerships that have already occurred. Some
examples in this area include the Philadelphia-based electric utility company
PECO Energy Company joining with the UK-based nuclear electric company British
Energy to purchase and/or operate nuclear plants in the United States. In
addition, France Telecom and Deutsche TeleKom each owns a position in the
US-based telecommunications provider Sprint Corporation.

  Turning to just US-based utility companies, we have seen an acceleration in
the merger and acquisition activity that has been occurring for some time now.
Recent activity in this region has included the natural gas company El Paso
Energy Corporation proposing to buy Fund holding Sonat Inc., another natural gas
pipeline company. Global Crossing Ltd., a provider of global long-distance
telecommunications facilities and services, which has agreed to purchase the
telecommunications provider Frontier Corporation, a Fund holding, has found
itself in a bidding war with Qwest Communications. On the electric side,
Denver-based New Century Energies, Inc. and Minneapolis-based Northern States
Power have announced plans to merge operations.

  This heightened level of activity among utilities might imply the opportunity
for enhanced growth driven by both revenues and cost reductions. Combining
common operations, increased usage of existing and new technologies over a
larger operating base and labor force rationalization may all result in reduced
expenditures. With the prospects for growth seemingly improving as a result of
the current consolidation trend in the utility industry, we expect to see
attractive investment opportunities.

PORTFOLIO MATTERS

During the first half of 1999, the Fund's overweighted strategy in
European-based utility

                                       116
<PAGE>   118

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

stocks was negatively impacted by the surprising strength in the US dollar
relative to the euro. Reduced economic growth estimates for the region and
nervousness over the direction of interest rates both in the United States and
abroad, coupled with the military action in Kosovo, contributed to this euro
weakness. Fundamentally, we believe the outlook for many of the Fund's holdings
in the European region has improved. Increased usage of the Internet is driving
demand for basic telecommunications services, and better pricing with improved
technology is raising the penetration and usage of mobile telephones. This has
been particularly evident in the results from Italy, Spain and the United
Kingdom. Finally, with continued higher interest rates in the United States a
possibility and considering the adverse derivative effects that they may have on
emerging markets, the assessment of risk versus return among global utilities
remains a challenge.

  The issue of Year 2000 (Y2K) compliance has also had an impact on the
composition of the Fund's portfolio. Y2K testing is an issue of some prominence
at certain agencies regulating utilities such as the Department of Energy, the
Nuclear Regulatory Commission and the Federal Communications Commission, among
many others. We have had concerns as to the level of Y2K preparedness among
utility companies, especially those in emerging markets. Consequently, we have
underweighted the portfolio of equity holdings in emerging markets.

PORTFOLIO ACTIVITIES

In the first half of 1999, we continued to reduce and eliminate holdings that no
longer fit our investment criteria and to add to existing positions and new
holdings as the opportunities arose. For instance, during the June quarter we
added to one domestic utility company, Houston-based Reliant Energy, Inc. The
company provides both electric and natural gas to consumers. The company also
has interests in South American electric utilities. Recent news coming from the
Texas regulatory authorities has been constructive for the company's outlook. We
also eliminated three holdings and reduced weightings in six holdings based on
valuation and fundamental considerations.

IN CONCLUSION

We appreciate your investment in Global Utility 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.--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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

                                       127
<PAGE>   129
- --------------------------------------------------------------------------------

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) 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.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--GOVERNMENT BOND FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

During the six months ended June 30, 1999, the US fixed-income market was
characterized by a dramatic shift in investor psychology that saw a
flight-to-quality mentality transformed into a flight-from-quality bias.
Specifically, interest rates trended higher and the yield curve flattened as
investors priced in the possibility that the Federal Reserve Board would seek to
tighten monetary policy by mid-year. The Federal Reserve Board's shift in policy
toward a tightening bias was being driven by its concern that the domestic
economy was growing at a pace sufficient to rekindle the inflationary fires.
Furthermore, many investors were convinced that the liquidity problems that had
developed as a result of both the deterioration of the emerging market economies
and the excessive amount of financial leverage in the system were now behind us.
On June 30, 1999, the Federal Reserve Board raised its overnight funds rate by
0.25% to 5.00% and simultaneously shifted to a neutral posture.

  As we entered the six-month period ended June 30, 1999, the overall tone of
the Treasury market was relatively upbeat since most investors were expecting
technical conditions to remain strong and the Federal Reserve Board to continue
on an accommodative road as the domestic economy began to feel the negative
impact of the rising trade deficit. Although the Federal Reserve Board had moved
from an accommodative bias to a neutral posture, investors still believed it was
possible for the Federal Funds rate to reach 4% by mid-year since the economic
environment slowed down. However, this optimism would not last as first quarter
US gross domestic product growth rose an unexpectedly strong 4.5%, spurred on by
consumer spending, which jumped 6.7%. Clearly, consumers were benefiting from a
low unemployment rate and the wealth effect generated from a booming stock
market.

  Overseas, Asian countries, at the heart of the crises in 1998, exhibited the
beginnings of economic recovery. This global recovery led to fears of a
rekindling of inflation. Commodities, such as copper, gained in price. More
importantly, the price of oil surged, spurred on mainly by an agreement by the
OPEC to limit production, but also on expectations of increased demand by
recovering economies. While the reported producer price index for April showed
only a 0.2% increase (excluding food and energy), the core consumer price index
(CPI) rose a greater-than-expected 0.7% for April, well above expectations and
the largest increase since April 1989. At this point, most investors believed
the Federal Reserve Board would raise short-term interest rates by at least 25
basis points (0.25%) at the late June Federal Open Market Committee (FOMC)
meeting.

  Although investors were relieved to see a complete reversal of April's
inflationary picture in May and June (particularly as the CPI was unchanged),
most investors still believed the Federal Reserve Board would remain committed
to a course of tighter monetary policy. The forward market, which had priced in
approximately 120 basis points prior to the most recent inflationary release,
still projected a 50 basis point--75 basis point aggregate move by the Federal
Reserve Board at mid-month. The yield on the 30-year Treasury bond, which began
the year at 5%, traded to a high of 6.17% in June. At that time we were not
surprised by the Federal Reserve Board's increase of 25 basis points at its June
30, 1999 FOMC meeting, followed by a wait and see attitude to gauge the strength
of the economy and any inflationary pressures that may build.

PORTFOLIO MATTERS

In anticipation of the volatile interest rate environment, we increased our
allocation to mortgage-backed securities (MBS) throughout the year. We started
1999 with a minimal MBS position. However, expanded prospectus language allowed
us a greater participation in MBS, and currently the Fund has a 41% net asset
allocation in this sector. As a result, the Fund is now benchmarked against the
Salomon Government Mortgage Index given the enhanced flexibility the Fund has
relative to MBS. Furthermore, we believe this allows the Fund to be more closely
aligned with its competitive Lipper peer group. Concurrently, our Treasury
holdings fell from approximately 50% of net assets to 35% during the same
period, well below the benchmark allocation of 46%. We initially reduced our
allocation to Government agency debentures in line with the 15% weighting of the
Salomon Government/Mortgage Index. However, we recently increased our weighting
to 25% of net assets. We believed that the intermediate sector of the agency
yield curve contained some very attractive relative values following the spread
widening that characterized this market since the beginning of the second
quarter of 1999. We sold short-term and intermediate-term Treasury issues and
invested the proceeds in similar maturity agency securities. We shortened
duration when we shifted to the new Index, and have held it steady at 4.7 years,
in close proximity to the Index.

                                       130
<PAGE>   132

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

  We extended the average life of the Fund modestly to 8.4 years through agency
debentures as interest rates rose and spreads widened. With respect to MBS, we
focused on 30-year collateral with a particular interest on higher coupon issues
given our expectations for interest rates to rise through the period.
Unfortunately, the premium for this type of collateral rose as interest rates
increased, making it difficult to accumulate the amount we wanted. Recently, we
also focused on short-dated agency securities where breakeven levels relative to
Treasury issues were attractive.

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.

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. These unaudited financial statements reflect all adjustments which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a normal recurring
nature. 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.

  (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.

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 0.50% 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.

  For the six months ended June 30, 1999, Merrill Lynch Security Pricing
Service, an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, a
subsidiary of ML & Co., earned $1,634 for providing security price quotations to
compute the Fund's net asset value.

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 FUND, INC.--HIGH CURRENT INCOME FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. In Japan, there are not yet clear signs that
Japan's economy is improving. There were growing signs of improvement in some
emerging economies (most notably South Korea and Mexico), although concerns
remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

PORTFOLIO MATTERS

The first half of 1999 was characterized by a relentless rise in US Treasury
yields, robust domestic economic growth and volatile equity markets. In this
environment, the high-yield asset class performed quite well. Specifically, the
unmanaged CS First Boston Global High Yield Index registered a total return of
+2.82% for the six months ended June 30, 1999, in sharp contrast to the ten-year
US Treasury return of -6.52% for the same period. (The hefty coupon associated
with high yield issues, as well as different supply and demand dynamics and
investor sentiment, all contributed to the divergence between the two markets.)
The Standard & Poor's 500 (S&P 500) Index advanced 12.38% during the same
period. The yield spread between the High Yield Index and US Treasury securities
of similar maturity narrowed to 574 basis points (5.74%) at June 30, 1999,
compared to 657 basis points at year-end 1998.

  New-issue volume has slowed from last year's frenetic pace, resulting in
weaker flows into high-yield mutual funds. Year-to-date issuance (in terms of
proceeds) was about 37% below the year-ago period. Credits in the media/
telecommunications sector continue to account for the largest portion of new
issues, about 36%. However, one of the largest issuers during the period was a
commodity chemical company--Lyondell Chemical Co.--that completed a $2.4
billion, three-tranche transaction in May. We established positions in two of
the tranches and believe that the company is well positioned for the next
industry cyclical upturn.

  Default rates continued to rise, according to data tracked by Moody's
Investors Service, Inc. (Moody's) and Donaldson Lufkin & Jenrette (DLJ) (a
leading high-yield underwriter). For the 12 months ended June 1999, Moody's
reports that the default rate (based on percentage of principal amount
outstanding) equaled 5.04% (up from 3.75% for 1998), while DLJ reported a rate
of 2.78% (up from 1.28% in 1998). Despite these gloomy statistics, we note that
as of this date, several sectors of the high-yield universe--energy, paper and
steel--are benefiting from rising product prices.

  Against this backdrop, the Fund's Class A Shares had a total return of +3.71%,
outperforming the unmanaged CS First Boston High Yield Index, which had a total
return of +2.82% for the six-month period ended June 30, 1999. The Fund's
results were aided by our relatively high exposure to emerging markets issues
(11.1% as compared to 7.1% for the Index) that have recovered from last year's
dramatic sell-off. Our overweighting in the paper/packaging and
utility/independent power producer sectors also aided the Fund's performance, as
did our underweighting in healthcare, the worst-performing sector during the
period. Positive event risk affecting several credits in the Fund also had a
favorable impact on performance. Among these were AT&T Corp.'s announced plans
to acquire (in a two-step transaction) MetroNet Communications (a Canadian
competitive local exchange carrier) and Sprint Corp.'s planned takeover of
American Telecasting Inc. (ATEL), an operator of wireless cable TV systems. The
ATEL transaction announcement caused its bonds, which had been trading at

tics--announced premium tender offers for their
bonds.

  For the better part of May and June, the high-yield market was plagued by
asset outflows. While mutual funds are not the only institutional buyers of
high-yield debt, they are important players. In contrast, the Fund received a
healthy inflow in June, while May outflows were very modest. Hence, we were able
to take advantage of a soft market, and found some excellent relative values.
Our largest purchases in the new-issue market were the bonds of Consolidated
Container Co. (a leading North American manufacturer of rigid plastic
containers) and Caithness Coso, a special purpose corporation that issued the
bonds on behalf of partnerships, which own geothermal power projects in
California. We favor the packaging and independent power sectors because of
their stable cash flows. Both of these credits are among the Fund's largest
holdings. In the secondary market, we established a new position in Clearnet
Communications, a leading Canadian wireless company. We were able to purchase
this senior discount bond at roughly four points below the price at which it was
issued back only in April. Our major sales were a preferred share issue of
Coastal Finance, which had its ratings move to investment grade, and a senior
note issue of Lenfest Communications. This cable TV company's bonds tightened to
investment-grade spreads following AT&T's announcement in early May that it
would acquire the remaining 50% of the company that it did not already own.

  At June 30, 1999, communications and media remained our largest broad industry
category, equaling 27.6% of the Fund's total market value. Of the more narrowly
classified sectors, the largest industries were: communications, 12.0%; cable
(domestic and international), 8.5%; utilities/IPPs, 8.5%; packaging/paper and
forest products, 8.2%; and broadcasting/printing and publishing, 7.1%. Foreign
bonds totaled 22.2% of the Fund's market value, with emerging market issues
(primarily Latin American corporate bonds) accounting for 11.1% of market value.
At June 30, 1999, the average maturity of the Fund was 6.8 years, and cash and
cash equivalents amounted to 7.2% of market value.

IN CONCLUSION

We appreciate your investment in High Current Income Fund of Merrill Lynch
Variable Series Funds, Inc., and we look forward to sharing our investment

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--HIGH CURRENT INCOME 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, 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. These unaudited financial statements reflect
all adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal recurring nature. 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 realized capital
gains 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
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: 0.55% of such average daily net
assets not exceeding $250 million; 0.50% of such average daily net assets in
excess of $250 million but not more than $500 million; 0.45% of such average
daily net assets in excess of $500 million but not more than $750 million; and
0.40% of such average daily net assets in excess of $750 million. For the six
months ended June 30, 1999, the aggregate average daily net assets of the Fund
and Prime Bond Fund was approximately $1,100,383,000.

  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 six months ended June 30, 1999, Merrill Lynch Security Pricing
Service, an affiliate of Merrill Lynch, Pierce, Fenner & Smith Incorporated, a
subsidiary of ML & Co., earned $1,798 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
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

The equity market's first quarter rally led the Standard & Poor's 500 Composite
(S&P 500) Index to its first-ever close above the 1,300 level on March 15, 1999.
In April, optimism regarding corporate earnings prospects powered the equity
market's continued broad-based advance. During that month, the Dow Jones
Industrial Average, which is heavily weighted with cyclical stocks, posted its
best one-month gain since January 1987. In comparison, the S&P 500 Index
produced a more modest total return of +3.87% for the same month. The market
displayed evidence of a rotation out of long-favored growth stocks into value
stocks. The S&P 500 Index's energy, basic industries and capital goods sectors
were the best-performing groups during the month, and in direct contrast to the
trend of recent history, small and mid cap stocks handily outperformed large cap
issues during April.

Trading once again became choppy in May, as renewed fears of inflation began to
take their toll on both the 30-year US Treasury bond and the equity market as
well. While small stocks continued to advance during the month of May, the S&P
500 Index (which reached an all-time high of 1367.56 on May 13) fell back below
the 1,300 level by May 26, 1999. Powered by a 20-point rally on the last day of
trading for the month, the Index once again managed to finish the month just
above the 1,300 level, which it had first broken through more than two months
earlier.

  Mired by mixed signals regarding an uncertain inflationary outlook, the S&P
500 Index spent most of June in a narrow range around the 1,300 level. Four
weeks of this trading range were all but forgotten on the last three days of the
month, as renewed evidence of still moderate inflationary pressures in the
economy put such fears into the background yet again. A strong rally saw the S&P
500 Index gain over 57 points in the last three days of June. This momentum was
capped off by the Federal Reserve Board's modest increase of 25 basis points
(0.25%) in the Federal Funds rate and its shift to a neutral bias on the last
day of the month. This allowed the Index to finish the first half of 1999 at yet
another record high of 1,372.71, surpassing the level reached in the middle of
May. For the three-month and six-month periods ended June 30, the S&P 500 Index
had total returns of +7.05% and +12.38%, respectively. However, unlike most
recent periods, the latest leg of the bull market in US equities was led in the
second quarter by mid-capitalization and smaller-capitalization stocks, as the
unmanaged S&P MidCap Index and S&P Small Cap Index both posted double-digit
advances during the second quarter of 1999.

PORTFOLIO MATTERS

For the six months ended June 30, 1999, Index 500 Fund's Class A Shares had a
total return of +12.07%. Since inception (December 13, 1996) through June 30,
1999, the Fund's Class A Shares had a total return of +94.15%. The Fund's
benchmark, the unmanaged S&P 500 Composite Index, produced total returns of
+12.38% and +96.06% for the same six-month and since inception periods,
respectively.

  Cash inflows into the Fund continued at a solid pace throughout the first half
of 1999, and combined with the continuing gains in the market, the Fund's net
assets grew from $403.2 million on December 31, 1998 to $591.3 million on June
30, 1999. This represents an increase of more than 46% in the Fund's net assets
during this period. The principal investments of the Fund are a fully
replicating portfolio of all 500 stocks in the Index, plus a long position in
S&P 500 futures contracts, which are used to quickly convert most daily cash
flows into the Fund into equity exposure. At the end of June, the Fund's equity
portfolio was valued at $573.0 million. In addition, the Fund held a long
position of 53 S&P 500 futures contracts. As always, it is the Fund's goal to be
100% invested in the S&P 500 Index at all times.

  The first half of 1999 was an active period for composition changes within the
Index. In response to this activity, we initiated positions in the following
stocks during the first quarter of the year: McKesson HBOC, Inc., SouthTrust
Corporation, AmSouth Bancorporation, CenturyTel, Inc. and Kansas City Southern
Industries, Inc. In the second quarter of 1999, we added: Watson Pharmaceutical,
CMS Energy Corporation, AFLAC Incorporated, Delphi Automotive Systems
Corporation, Paine Webber Group Inc., Wellpoint Health Networks Inc., Nabisco
Group Holdings Corp., Florida Progress Corporation, Office Depot, Inc., Network
Appliance, Inc., Best Buy Co., Inc. and Vulcan Materials Company.

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. These unaudited financial statements reflect all adjustments which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a normal recurring
nature. 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

                                       173
<PAGE>   175
- --------------------------------------------------------------------------------

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. 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.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--INTERNATIONAL EQUITY FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

Once again we are looking back upon a period of remarkable events in the world's
equity markets. Over the six months ended June 30, 1999, the unmanaged Morgan
Stanley Capital International (MSCI) World (Ex-US) Index, returned +4.5% in US
dollar terms. Over the same period, the unmanaged MSCI Emerging Markets Free
Index returned +39.9% in US dollar terms.

  However, these results mask wide divergences between some of the world's
equity markets. Within the developed market universe, the Pacific Basin,
excluding Japan, rose by 26.0%, while Japan itself gained 20.8%. These advances
were exceeded by the Asian Emerging markets, which collectively rose by 54.3%.
(References to markets are measured by Morgan Stanley indexes for the six months
ended June 30, 1999 and are in US dollar terms.) Outside Japan, the gains marked
the early stages of recovery from the crises that had severely hit these markets
over the previous 18 months. The economies in the region continued to benefit
from global monetary easing, initiated in the United States with two interest
rate cuts in October 1998, and followed by similar cuts in nearly all other
major countries.

  Within the Asian region, improving trade figures, greater currency stability
and falling interest rates formed a base for recovery. The recovery was also
assisted by International Monetary Fund (IMF) funding and, in many countries, a
clear political will to adhere to the conditions set by the IMF for improving
the domestic financial systems. Most notable among the successes were Indonesia,
South Korea and Malaysia Free. These markets rose by 110.9%, 77.9% and 77.5%,
respectively, during the six months ended June 30, 1999. In South Korea, the
government's efforts were also rewarded with a significant re-rating of its
sovereign risk. Among the largest gains in the developed markets were the 60.4%
and 31.5% increases recorded by Singapore and Hong Kong, respectively.
Notwithstanding the outperformance produced by Asian stock markets, we believe
that problems remain in that there is still too much production capacity and the
ever-present threat of deflation. These issues hang over the whole region,
including Japan. However, Japan has also been showing some sporadic signs of
recovery, such as the housing sector, triggered by the various stimulative
packages implemented by the government. However, first quarter gross domestic
product figures showing growth at an annualized rate of 7.9% probably exaggerate
the pace of recovery.

  In contrast with Asia, equity markets in other major regions performed
relatively poorly over the six-month period ended June 30, 1999. Continental
European developed markets actually fell by 4.4% over the six months, while the
United Kingdom rose by only 2.6%. Eastern European and Middle Eastern emerging
markets appeared to demonstrate a strong recovery with the unmanaged
International Finance Corporation Investables Europe and Middle East Index
rising by 29.4%. However, this figure masked a mixed picture with Russia
bouncing back dramatically (up 133.7%) from a very low base following last
year's bond default. Other emerging European markets were not so fortunate, for
example, Hungary fell 8.8%.

  In January 1999, Europe saw the introduction of the euro as a common currency
for 11 countries, including Germany, France, Italy, the Netherlands and Spain.
This region had performed particularly well in the 12 months leading up to the
launch of the new currency and had reached extremely high valuation levels amid
great optimism regarding the benefits of the single currency. However, the
collapse of the Russian financial markets in August 1998 led to massive losses
for many European banks and sharp falls on European markets. The region's stock
markets have underperformed consistently for the six months ended June 30, 1999,
a trend that has been exacerbated for US-dollar based investors by a near 12%
depreciation of the euro since its launch.

  The Latin American equity markets were overshadowed at the beginning of the
calendar year by their current account deficits. Defaults on some Brazilian
local government bonds impacted both currencies (Brazil was forced to float the
real in January) and equity markets at the start of 1999. However, Latin
American markets rallied sharply after the real's devaluation, aided by signs
that the recession in Brazil may be a brief one. The Latin America Index rose by
31.0% over the first half of 1999.

  Throughout all of these events, the US economy continued to grow and prosper.
The strength of the US equity market underpinned the US consumer-spending
boom--a boom so strong that for the first time in over 20 years the US savings
ratio became negative. Until recently, the absence of tangible signs of
inflation, combined with the need for the US economic engine to power the rest
of the world, helped keep US bond yields on a flat to

                                       176

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

downward trend. However, this downward bias was reversed by May and June with
the Federal Reserve Board raising interest rates by 0.25% on June 30, 1999.

PORTFOLIO MATTERS

During the six-months ended June 30, 1999, the Fund experienced a sharp
improvement in performance relative to its benchmark. The Fund's Class A Shares
had a total return of +10.6% for the six months ended June 30, 1999, while the
Fund's benchmark MSCI World (Ex-US) Index returned +4.5% for the same period.

  For the six-months ended June 30, 1999, the Fund was underweighted in
Continental Europe, which benefited performance. In the last half of the
six-month period, we reduced the scale of the underweighting to approximately
1.5% relative to the benchmark, from about 6% at the beginning of the calendar
year.

  The Fund started the six month period overweight in the UK market relative to
the benchmark, having raised the exposure in late 1998 on the belief that
investors had underestimated both the scope of interest rate cuts and the impact
these cuts would have on ensuring that the UK economy would avoid recession. In
May we reversed this position as it became clear that investors had caught up
with the reality of a stronger economy. At the same time, we increased the
Fund's exposure to Germany on the belief that pessimism toward the German
economy was overdone considering the weaker currency, lower interest rates and
less tight fiscal policy at a time of rising expectations of global demand.

  We were almost neutral in Japan for most of the period relative to the
benchmark (although the Fund had a much higher weighting than many international
funds) and moved to an overweight position in March, just as the market began a
period of outperformance. We believed that investor perceptions toward the
Japanese market would begin to improve, despite the many well-known pressures
that are faced there. The yen proved the strongest of the major currencies over
this period.

  The change in Federal Reserve Board policy in October sparked a major rally in
global markets in late 1998, which has been extended in 1999 by consistent
upgrading of forecasts for the world economy. The recent change of direction by
the Federal Reserve Board has been carefully staged and timed to limit any risk
of cutting off this global rally. We consistently held low cash levels during
this period to ensure that the Fund benefited from this strong performance.

  In the first quarter of 1999, we became positive on the prospects of the
global economy, which influenced our decisions to raise exposure to commodity
stocks and regions; to emerging markets; to value stocks in preference to growth
stocks and also to smaller stocks around the world. All of these decisions added
to the performance of the Fund.

IN CONCLUSION

The improvement in the Fund's performance relative to its benchmark also
coincided with the completion of various changes in the management of the Fund
that were initiated in April 1998. These changes included the resetting of the
Fund's benchmark. We are now placing greater emphasis on combining the bottom-up
stock selection process with top-down asset allocation. We believe that this
strategy has helped improve the Fund's investment returns.

  Over recent months some trends have started to emerge in global equity
markets. The emerging markets of Asia have already started their recoveries.
There are also signs that commodity markets are beginning to pick up.

  We appreciate your investment in Merrill Lynch 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,

(a) American Depositary Receipts (ADR).

(b) Global Depositary Receipts (GDR).

(c) Warrants entitle the Fund to purchase a predetermined number of shares of
Common Stock and are non-income producing. The purchase price and number of
shares are subject to adjustment under certain conditions until the expiration
date.

(d) Non-income producing security.

(e) The security may be offered and sold to "qualified institutional buyers"
under Rule 144A of the Securities Act of 1933.

(f) Optimized Portfolio As Listed Securities (OPALS) are investments that are
exchange quoted and provide an equivalent investment exposure to that of the
specific Morgan Stanley Capital International (MSCI) country index.

(g) The rights may be exercised until 9/21/1999.

(h)
The rights may be exercised until 6/30/2003.

(i)
Securities held as collateral in connection with open financial futures
contracts.

(j)
Brady Bonds are securities which have been issued to refinance commercial bank
loans and other debt. The risk associated with these instruments is the amount
of any uncollateralized principal or interest payments since there is a high
default ratio of commercial bank loans by countries issuing these securities.

++ Effective February 16, 1999, the Company's Board of Directors adopted a
change in valuation for Malaysian securities. The Company will utilize a
Malaysian exchange rate of 3.80 and record an estimated exit tax on the value of
any investments made before February 15, 1999, based upon its value as of August
31, 1998, in the amount of 30% through March 31, 1999, 20% from April 1, 1999
through May 31, 1999 and 10% from June 1, 1999 through August 31, 1999. These
changes are due to the capital controls implemented by the Malaysian government,
which froze the Malaysian ringgit at 3.80 until September 1, 1999 and initiated
a tax at various rates, as described above, on any funds repatriated from
Malaysia.

* Commercial Paper and certain US Government Obligations are traded on a
discount basis; the interest rates shown reflect the discount rates paid at the
time of purchase by the Fund.

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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 of 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.

                                       196
<PAGE>   198
- --------------------------------------------------------------------------------

- - 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.

- - 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 futures
transactions and post-October losses.

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--NATURAL RESOURCES FOCUS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

The Fund's performance rebounded during the first half of 1999. Commodity prices
and the stocks of resource companies continued to enjoy strong recoveries from
the lows reached following the recessions in Asian and other emerging markets.
All commodity groups delivered double-digit gains 1999 year-to-date, with the
only exception being the gold sector, which is suffering from the lack of
inflationary pressures and central bank selling.

  During the six months ended June 30, 1999, the Fund's Class A Shares had a
total return of +25.79%. The Fund outperformed the +18.14% total return of the
unmanaged Morgan Stanley Capital International (MSCI) Natural Resource Fund
Index, and on a trailing 12-month basis ended June 30, 1999, the Fund's Class A
Shares' total return exceeded that of the Lipper Natural Resources Fund Average
of +2.50%.

  The recovery in resource stocks and strong Fund performance confirmed our
belief that resource stock prices had discounted problems facing the sector. As
world economic conditions continued to show signs of improvement, resource
investments continued to offer the potential for positive returns. This is
particularly true in selected energy and paper/forest product investments.

  Increased exposure to energy investments, particularly North American natural
gas producers and oil service stocks, helped the Fund's investment results. Ten
of our independent oil and gas production and oil service stocks delivered
exceptionally strong total returns. The surplus of natural gas in storage
resulting from the historically warm winter has continued to decline, and
storage is similar to levels in 1998. Production continues to decline from the
low level of drilling, so we believe that gas prices could rebound if normal
winter weather patterns prevail in the upcoming heating season. We continued to
add to our holdings of natural gas stocks since we believe that natural gas
prices could rise sharply given current industry supply and demand dynamics,
while we continued to reduce holdings of large-capitalization international oil
companies. Consolidation activity in the group has pushed valuation levels to
the high end of historic ranges. This provides an element of risk given our less
favorable near-term outlook for their refining and chemical operations. While we
have added to our oil service holdings, we are reluctant to add to current
positions given the lack of earnings visibility, as well as concerns that oil
industry consolidation may mute overall service activity. Proceeds from the sale
of our larger oil positions were directed to domestic integrated oil companies,
independent gas producers and natural gas pipelines with exploration programs.

  We continued to increase our exposure to the paper and forest products
industry. Positive supply and demand fundamentals continued to evolve in the
forest and paper products area, as capital spending has been pared in the wake
of the Asian crisis. In addition, merger and acquisition activity continues in
the group which has resulted in further capacity closures. Containerboard prices
currently are approaching the levels seen in 1997, prior to the onset of the
Asian recession. In addition, the increase in pulp prices may filter into the
pricing of other grades.

  We dramatically increased our paper weighting over the past six months. We
initiated holdings in St. Laurent Paperboard Inc. and Tembec Inc., two low-cost
Canadian producers of containerboard and pulp. We also initiated holdings in
Abitibi-Consolidated Inc., Westvaco Corporation and Smurfit Jefferson Group PLC.
Assets for the purchase of these holdings came from the sale of Champion
International Corp., Consolidated Paper, Bowater Inc. and the partial sale of
Riverside Forest Products Limited. Appreciation in these stocks had eroded their
valuation support. The larger-capitalization paper stocks have appreciated over
50% off their lows of last year. However, past cyclical moves in the group
suggest the possibility for additional significant gains.

  Chemical stocks have rebounded with the improvement in international economic
conditions. However, we continue to be concerned about new capacity additions
scheduled to start production, as well as the impact of rising energy-based
feedstock costs. Therefore, we have further underweighted the Fund's exposure to
the chemical group. We sold our E.I. duPont de Nemours & Co. position since we
believed that the stock price reflected the potential of its life-sciences
division. We also sold our fertilizer producer IMC Global Inc. The dramatic
decline in farm income may have dimmed near-term prospects, and new capacity
additions are becoming visible on the investment horizon. We are in the process
of reviewing our chemical weighting in light of improved global commodities;
however, we believe that this area could lag investments in other resource
sectors.

  We have continued to be selective sellers of metal and mining issues, but
returned Freeport McMoRan Copper & Gold Inc. to our metals

                                       199
<PAGE>   201
- --------------------------------------------------------------------------------

holdings. We also added to our holding in Australian copper producer M.I.M.
Holdings Limited The base metals group has rebounded in sympathy with optimism
about recovering economies. However, a number of temporary capacity closures
have resulted in a commodity short-squeeze. Should prices continue to rise, we
fear that these idled mines could return to production and mute a recovery in
the sector. We eliminated many of our Japanese mining holdings when their stock
prices recovered with the overall market rally in Japan, although in hindsight
we could have let the positions run further.

  While gold stocks did not hurt Fund performance in relative terms in 1998, the
group began to diverge from other resource stocks in 1999. A two-day rally in
early May, sparked by inflationary fears from remarks by Federal Reserve Board
Chairman Alan Greenspan, was stopped cold upon the announcement the United
Kingdom would sell half its gold reserves. Given fears of further central bank
sales, we dramatically sold the bulk of our gold holdings. The current weighting
of 2% of net assets puts the Fund closer to gold's weighting in the unmanaged
MSCI Natural Resource Index, and below the weighting held by most of our
competitors in the resource fund universe. The reduced gold exposure helped to
improve our performance.

  Should the trend in improving global economic conditions persist, we believe
that continued positive investment results are possible during the remainder of
the year. However, we expect our strong concentrations in natural gas and
selected forest and paper stocks to deliver strong results that are somewhat
insulated from global market conditions. Our investment focus on companies
subject to improving supply and demand conditions have generated strong relative
and absolute returns. With the process of restructuring the Fund nearly
complete, we are 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.

++ Effective February 16, 1999, the Fund's Board of Directors adopted a change
in valuation for Malaysian securities. The Fund will utilize a Malaysian
exchange rate of 3.80 and record an estimated exit tax on the value of any
investments made before February 15, 1999, based upon its value as of August 31,
1998, by 30% through March 31, 1999, 20% from April 1, 1999 through May 31, 1999
and 10% from June 1, 1999 through August 31, 1999. These changes are due to the
capital controls implemented by the Malaysian government, which froze the
Malaysian ringgit at 3.80 until September 1, 1999 and initiated a tax at various
rates, as described above, on any funds repatriated from Malaysia.

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

                                       209
<PAGE>   211
- --------------------------------------------------------------------------------

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. Distributions in excess of realized
capital gains 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

  MLAM is responsible for the management of the Company's funds and provides the
necessary personnel, facilities, equipment and certain other services necessary

  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 six months ended June 30, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a subsidiary of ML & Co., earned $1,931 in commissions on the
execution of portfolio security transactions.

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.,

JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. In Japan, there are not yet clear signs that
Japan's economy is improving. There were growing signs of improvement in some
emerging economies (most notably South Korea and Mexico), although concerns
remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

MARKET OVERVIEW

During the six months ended June 30, 1999, the US fixed-income market was
characterized by a shift in investor psychology that saw a flight-to-quality
mentality transformed into a flight-from-quality bias. Specifically, interest
rates trended higher and the yield curve flattened as investors priced in the
possibility that the Federal Reserve Board would seek to tighten monetary policy
by mid-year. The Federal Reserve Board's shift in policy toward a tightening
bias was being driven by its concern that the domestic economy was growing at a
pace sufficient to rekindle the inflationary fires. Furthermore, many investors
were convinced that the liquidity problems that had developed as a result of
both the deterioration of the emerging market economies and the excessive amount
of financial leverage in the system were now behind us. On June 30, 1999, the
Federal Reserve Board raised its overnight funds rate by 0.25% to 5.00% and
simultaneously shifted to a neutral posture.

  As we entered the six-month period ended June 30, 1999, the overall tone of
the Treasury market was relatively upbeat since most investors were expecting
technical conditions to remain strong and the Federal Reserve Board to continue
on an accommodative road as the domestic economy began to feel the negative
impact of the rising trade deficit. Although the Federal Reserve Board had moved
from an accommodative bias to a neutral posture, investors still believed it was
possible for the Federal Funds rate to reach 4% by mid-year since the economic
environment slowed down. However, this optimism would not last as first quarter
US gross domestic product growth rose an unexpectedly strong 4.5%, spurred on by
consumer spending, which jumped 6.7%. Clearly, consumers were benefiting from a
low unemployment rate and the wealth effect generated from a booming stock
market.

  Overseas, Asian countries, which had been at the heart of the crises in 1998,
exhibited the beginnings of economic recovery. This global recovery led to fears
of a rekindling of inflation. Commodities, such as copper, gained in price. More
importantly, the price of oil surged, spurred on mainly by an agreement by the
OPEC Countries to limit production, but also on expectations of increased demand
by recovering economies. While the reported producer price index for April
showed only a 0.2% increase (excluding food and energy), the core consumer price
index (CPI) rose a greater-than-expected 0.7%, well above expectations and the
largest increase since April 1989. At this point, most investors believed the
Federal Reserve Board would raise short-term interest rates by at least 25 basis
points (0.25%) at the late June Federal Open Market Committee (FOMC) meeting.

  Although investors were relieved to see a complete reversal of April's
inflationary picture in May and June (particularly as the CPI was unchanged),
most investors still believed the Federal Reserve Board would remain committed
to a course of tighter monetary policy. The forward market, which had priced in
approximately 120 basis points (1.20%) prior to the most recent inflationary
release, still projected a 50 basis point--75 basis point aggregate move by the
Federal Reserve Board at mid-month. The yield on the 30-year Treasury bond,
which began the year at 5%, traded to a high of 6.17% in June. At that time we
were not surprised by the Federal Reserve Board's increase of 25 basis points at
its June 30, 1999 FOMC meeting, followed by a wait and see attitude to gauge the

strength of the economy and any inflationary pressures that may build.

PORTFOLIO MATTERS

The Fund's investment strategy can best be labeled as cautiously optimistic.
From a duration perspective, we have maintained a slightly lower (0.05
year--0.20 year) profile than the benchmark Merrill Lynch Corporate Master
(C0A0) Index considering the bias toward higher interest rates during much of
the six-month period. Given the negative prevailing investor sentiment, we
raised our yield expectations relative to the trading band for the 30-year bond
to 5.75%--6.25% by the second quarter. If the yield of the bond reached the
higher end of our range, we expected to go slightly long relative to the Index
since we were not looking for interest rates to trend higher over the long term.
In essence, we believed that the foundation for a slowdown in the economy had
already been laid given the higher prevailing interest rates and the impact
exacted by recent stock market activity on the relationship of wealth to
spending.

  Consistent with recent strategy, we continued to seek higher coupon issues
with a spread to US Treasury Securities given our outlook for the near-term
direction of interest rates. We also remained committed to bigger, more liquid
issues. Our Treasury holdings have been kept to a minimum as we have focused on
the need to build current income. Furthermore, productivity and the correlation
to corporate profitability should be sufficient enough to sustain the overall
trend toward tighter yield spreads, although spreads during May exhibited
approximately 25 basis points of widening. Subsequent to the Federal Reserve
Board move, spreads had begun to trend inward, although spreads will widen in
the third quarter as new underwritings increase significantly. Corporate
issuance remained very active, with investor demand enthusiastic. In fact, the
majority of the new transactions have been significantly oversubscribed and well
received.

  With respect to security-specific issues, we began to add to several sectors
including energy-related issuers, paper producers and chemical companies. We
also added asset-backed securities and commercial mortgage-backed securities.
These sectors experienced improved economics yet still retained very attractive
yield advantages relative to Treasury securities. It was our intent to bring
these sectors up to a neutral benchmark weighting, although finding securities
has lately proved a challenge as a result of small supply and sporadic new
issuance in these sectors. During the later part of the period, we slightly
reduced the Fund's position in real estate investment trusts given the strong
performance this group experienced during early 1999. However, we still have an
overweighted position relative to the Index since we believe this sector will
continue to perform well, although we expect to bring this position closer to a
neutral posture as spreads compress. Retailing is another sector we have moved
to overweight, given the strong economic fundamentals characterizing that
industry.

INVESTMENT OUTLOOK

Going forward, we have formulated an investment strategy around our belief that
while the Federal Reserve Board may find it necessary to tighten interest rates
one more time in 1999, the long-term trend will be toward lower interest rates
as the economy slows. In line with this, we would expect to extend duration if
bond yields were to move toward the high end of our expected trading range.
However, given the high level of investor nervousness, we will continue to
emphasize higher coupons and liquid issues and corporate sectors trading at or
near the wide side of the historic spread relationships.

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

  (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

  MLAM is responsible for the management of the Company's funds and portfolios

0.50% of such average daily net assets not exceeding $250 million; 0.45% of such
average daily net assets in excess of $250 million but not more than $500
million; 0.40% of such average daily net assets in excess of $500 million but
not more than $750 million; and 0.35% of such average daily net assets in excess
of $750 million. For the six months ended June 30, 1999, the aggregate average
daily net assets of the Fund and the Company's High Current Income Fund was
approximately $1,100,383,000.

  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 six months ended June 30, 1999, the Fund paid Merrill Lynch Pricing
Service, an affiliate of Merrill Lynch, Pierce, Fenner & Smith, Incorporated,
$4,213 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
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. In Japan, there are not yet clear signs that
Japan's economy is improving. There were growing signs of improvement in some
emerging economies (most notably South Korea and Mexico), although concerns
remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

PORTFOLIO MATTERS

As of June 30, 1999, the Fund's asset allocation was: US stocks, 91% of net
assets and foreign stocks, 11%.

  We modestly expanded the Fund's allocation to US equities from 89% of net
assets to 91% during the six months ended June 30, 1999. We continue to believe
that investors may favor the shares of companies that offer a high degree of
earnings visibility in a steady growth/low inflation economy. On this basis,
technology remained the largest single group represented among our US equity
commitments. Positions established in the technology sector during the past
three months include Sun Microsystems, Inc., Xerox Corporation and Siebel
Systems, Inc. Consumer staples, including healthcare and financial services,
also continued to account for a significant proportion of US equity assets. New
positions in the consumer staples group included Merck & Co., Inc., while
Citigroup Inc. and The Goldman Sachs Group, Inc. are examples of new positions
in the financial services sector.

  We increased the Fund's foreign equity representation from 10% of net assets
to 11% during the first half of 1999. Our approach continues to reflect a
concentration on the shares of companies that we believe could add value to a
primarily US portfolio. The shares of Canadian and European companies continued
to predominate, although we also maintained commitments in Japanese, Asian and
Australian companies.

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,

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. These unaudited financial statements reflect all adjustments which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a normal recurring
nature. 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

                                       237
<PAGE>   239
- --------------------------------------------------------------------------------

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) Custodian bank--The Fund recorded an amount payable to the custodian bank
reflecting an overnight overdraft which resulted from management's estimate of
available cash.

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:
0.500% of the Fund's average daily net assets not exceeding $250 million; 0.450%

MERRILL LYNCH VARIABLE SERIES FUNDS, INC.--RESERVE ASSETS FUND
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

For the six-month period ended June 30, 1999, Reserve Assets Fund's net
annualized yield for Class A Shares was 4.47%. The Fund's 7-day yield as of June
30, 1999 was 4.44%. The average portfolio maturity was 71 days at June 30, 1999,
compared to 69 days at December 31, 1998.

THE ENVIRONMENT

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. Meanwhile, Japan reported its first quarter of
positive economic growth in more than a year. Some other emerging economies
(most notably South Korea and Mexico) are also showing some signs of
improvement, although concerns remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

  We continue to concentrate Fund investments in one-month commercial paper,
10-month--12-month intermediate-term notes and floating rate money market
instruments. We believe that this barbell strategy, coupled with one-third of
the Fund's assets in floating rate paper, is appropriate at this time. We
employed this strategy as we consider the possibility of an additional Federal
Reserve Board tightening in the near term but with low probability of
significant intervention as the year 2000 approaches.

  Longer term, we are slightly positive on the outlook for interest rates and
believe that current yields have sufficiently discounted negative news. In the
near term, we will continue to evaluate economic data as it becomes available,
responding accordingly to any necessary shifts.

  The Fund's composition at the end of June and as of our last report 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. These unaudited financial statements reflect all adjustments which
are, in the opinion of management, necessary to a fair statement of the results
for the interim period presented. All such adjustments are of a normal recurring
nature. 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 are valued at the most recent bid price or yield
equivalent as obtained from dealers that make markets in such securities. 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 additions to such securities daily to
ensure that the contract is fully collateralized.

  (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: 0.500% of the Fund's average daily net assets not
exceeding $500 million; 0.425% of average daily net assets in excess of $500
million but not exceeding $750 million; 0.375% of average daily net assets in
excess of $750 million but not exceeding $1 billion; 0.350% of average daily net
assets in excess of $1 billion but not exceeding $1.5 billion; 0.325% of average
daily net assets in excess of $1.5 billion but not exceeding $2 billion; 0.300%
of average daily net assets in excess of $2 billion but not exceeding $2.5
billion and 0.275% of average daily net assets in excess of $2.5 billion.

<PAGE>   249
- --------------------------------------------------------------------------------

  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.

  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 and redeemed during the periods corresponds to the
amounts included in the Statements of Changes in Net Assets with respect to net
proceeds from sale of shares 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
JUNE 30, 1999--SEMI-ANNUAL REPORT
- --------------------------------------------------------------------------------

DEAR SHAREHOLDER:

There were some conflicting signals regarding the future direction of the US
economy during the six months ended June 30, 1999. However, on balance the
economic outlook continued to be positive. The US economic expansion is ongoing,
especially in the consumer sector. Economic growth is not occurring at
inflationary rates, although the Organization of Petroleum Exporting Countries
(OPEC) successfully engineered a near-term increase in the price of crude oil.
Against this backdrop, the US Federal Reserve Board raised the Federal Funds
rate 0.25% at its June 30, 1999 meeting. Outside of the United States, signs of
growth are less apparent in other major industrial economies. European equity
markets have entered a period of consolidation, and investors are looking for
evidence of an economic pickup. In Japan, there are not yet clear signs that
Japan's economy is improving. There were growing signs of improvement in some
emerging economies (most notably South Korea and Mexico), although concerns
remain for others (such as Brazil and Argentina).

  In the US capital markets, long-term interest rates rose during the June
quarter. While the spread between yields on Treasury securities and corporate
issues of similar maturities has narrowed somewhat, it remains wide by historic
standards. Although the US stock market exhibited greater price volatility, its
advances broadened beyond relatively few growth stocks to the previously
languishing cyclical sectors.

PORTFOLIO MATTERS

During the first half of 1999, the environment for small-capitalization stocks
gradually improved with the pace of US economic activity. Recent economic
indicators, including employment data and the Producer Price Index (PPI), seemed
to confirm a strengthening in the US economy. Accordingly, the yield on the
30-year US Government bond has increased by about 100 basis points (1.00%),
causing a steepening of the yield curve. A strengthening economy is generally
favorable for small cap stocks, particularly small cap value stocks. The
steepening yield curve is a positive indicator for the value style of investing
because it often serves as an implied inflation forecast. To the extent that the
Federal Reserve Board is able to sustain the economic expansion with modest
interest rate increases, we anticipate further gains for small cap stocks.

  During the six-month period ended June 30, 1999, the Fund substantially
outperformed the unmanaged Russell 2000 Index. Total returns for the Fund's
Class A and Class B Shares were +19.58% and +19.48%, respectively, compared to
the total return of +9.28% for the Russell 2000 Index. Eleven out of twelve
economic sectors within the Russell 2000 benchmark index posted positive returns
in the first half of the year. The utility, energy, and transportation sectors
marked the sharpest gains, while the consumer staples sector declined. The
Fund's investment performance benefited from overweighted investments in the
energy and transportation sectors, and from underweighted investments in
financial services stocks. Sector positioning modestly benefited performance in
the six-month period; however, performance in excess of the Russell 2000 Index
resulted primarily from specific stock selection, as individual stocks sharply
outperformed their respective sectors in the benchmark index.

  Individual stocks that most benefited the Fund's investment results included
one medical device company and two telecommunications related stocks. Shares of
VISX Incorporated, a developer of proprietary technologies and systems for laser
vision correction, appreciated sharply based on strong growth in laser
procedures. Rapid share price appreciation and the large size of the position
combined to make VISX, Inc. a leading contributor to Fund results during the
six-month period. We significantly reduced the Fund's holdings in VISX since the
shares exceeded our valuation target. Shares of DSP Communications also rallied
in the first half of 1999. Asian market demand rebounded and the company
announced several important new customer wins. The company designs chip sets
used in wireless devices. Shares of Triquint Semiconductor, Inc., a manufacturer
of high performance integrated circuits, were also strong as earnings surpassed
the range of analysts' estimates and demand for the company's specialized
manufacturing capacity increased. Fund performance in the period was hindered by
an investment in CHS Electronics, Inc., an international distributor of
microcomputers and related products. Shares of CHS Electronics declined abruptly
in the period on concerns about the company's accounting for vendor rebates and
general weakness among computer distribution stocks. We sold the Fund's entire
position in CHS Electronics, Inc. based on deteriorating fundamentals.

  As small-capitalization stocks surged late in the six-month period, we
realized gains in stocks that had reached our internal price objectives, and
reinvested the proceeds in

                                       249
<PAGE>   251
- --------------------------------------------------------------------------------

stocks where we believed the risk-adjusted returns would be greater. In general,
we further increased the level of Fund diversification, realizing gains in
overweighted technology and economically sensitive industries, and investing
some of the proceeds in underweighted financial services stocks and other
interest rate sensitive areas.

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
outlook and strategy with you again in our next report to shareholders.

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. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. 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.

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. The 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 0.75% 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 0.15%
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 six months ended June 30, 1999, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, a subsidiary of ML & Co., earned $67,894 in commissions on the
execution of portfolio security transactions.

is the Company's transfer agent.

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