After raising the target short-term interest rate 17 times between June 2004 and
June 2006, the Federal Reserve Board (the Fed) finally opted to pause on August
8, 2006. This left the federal funds rate at 5.25%, where it remained through
year-end. In interrupting its two-year interest rate-hiking campaign, the Fed
acknowledged that economic growth is slowing, led by a downturn in the housing
market, but has maintained a cautionary view on inflation.

Overall, it was a good 12 months for U.S. equities, despite a significant
correction in the middle of the year that was largely triggered by rising
interest rates, inflation fears, elevated oil prices and geopolitical
uncertainties. Nevertheless, strong corporate earnings, abundant liquidity and
record merger-and-acquisition activity provided a solid backdrop for stocks.
Many international equity markets (with the notable exception of Japan)
performed even better, outpacing U.S. stocks for the fifth consecutive year.
Strength was especially notable in European equities and select emerging
markets.

Bonds experienced a more modest annual return than stocks. Interest rates and
bond yields moved higher for much of the year as bond prices, which move
opposite of yields, declined. Prices began to improve (yields fell) in the
summer as the economy showed signs of weakening and the Fed paused. Notably, the
Treasury curve inverted early in the year and remained inverted for much of
2006. The 10-year Treasury yield remained in the 4.5%-5% range most of the year
and ended December at 4.71%, well below the federal funds rate.

As we begin a new year, investors are left with a few key questions: Will the
U.S. economy achieve a soft landing, will the Fed reverse its prior policy and
cut interest rates, and how might these outcomes impact the investment climate.
As you navigate the uncertainties inherent in the financial markets, we
encourage you to start the year by reviewing your investment goals with your
financial professional and making portfolio changes, as needed. For more
reflection on 2006 and our thoughts on the year ahead, including our 10
predictions for 2007, please ask your financial professional for a copy of

www.blackrock.com/funds. We thank you for trusting BlackRock with your
investment assets, and we look forward to continuing to serve you in the new
year and beyond.

                                                         Sincerely,

                                                         /s/ Robert C. Doll, Jr.

BlackRock Series Fund, Inc.
Annual Report -- December 31, 2006
A Discussion With Your Funds' Portfolio Managers
================================================================================
BlackRock Balanced Capital Portfolio
================================================================================

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock Balanced Capital
Portfolio (formerly Mercury Balanced Capital Strategy Portfolio) returned
+14.09%. For the same period, the benchmark Standard & Poor's 500 (S&P 500)
Index returned +15.79%, the benchmark Lehman Brothers Aggregate Bond Index
returned +4.33% and the Lipper Mixed-Asset Target Allocation Growth Funds
(Variable Products) category had an average return of +10.41%. (Funds in this
Lipper category maintain a mix of between 60%-80% equity securities, with the
remainder invested in bonds, cash and cash equivalents.)

Despite substantial uncertainty and volatility, stock prices posted handsome
gains for the 12 months ended December 31, 2006. Changing investor perceptions
over the pace of economic growth, intensity of inflationary pressures, direction
of Federal Reserve Board (the Fed) monetary policy, appropriate level of
commodity prices and outlook for corporate profits were the primary market
drivers during the year. Ultimately, investors concluded that the expected
cessation of interest rate increases by the Fed and the significant decline in
energy prices would foster a more hospitable environment for equities. The value
style of investing continued to outpace the growth style of investing and
smaller-capitalization companies outperformed their larger brethren, though all
major style and capitalization categories produced positive returns for the
year. Gains in the fixed income market were more muted, with most of the
positive performance realized in the September quarter when bond investors began
to react favorably to the expected slowdown in economic growth and change in Fed
policy.

What factors most influenced Portfolio performance?

Asset allocation was favorable and equities substantially exceeded their
benchmark return while bonds slightly underperformed their benchmark. Within the
equity portfolio, good stock selection in the information technology sector was
the primary driver of the outperformance, led by better than 30% returns from
positions in Commscope, Inc., Cisco Systems, Inc. and Accenture Ltd. and by
having only a small position in Intel Corp., which declined more than 10% for
the year. Good stock selection in the consumer discretionary sector further
aided performance, led by solid gains from positions in McDonald's Corp.,
Limited Brands, Inc. and Comcast Corp. Our underweight position and good stock
selection in health care, the market's weakest-performing sector for the year,
also contributed to results, led by a near 25% gain in our holding in Baxter
International, Inc. and our avoidance of Amgen, Inc. and United Healthcare
Group, Inc., each of which declined more than 13% for the year. These areas of
outperformance more than offset relative weakness in the energy sector, where
poor stock selection detracted from Portfolio results. This was largely due to
our owning only a small position in Exxon Mobil Corp., which rose almost 40%,
and not owning any shares of Chevron Corp., which rose 34%. Our underweight
position in telecommunications, the market's strongest-performing sector for the
year, also impaired performance. In particular, we missed an 80% advance in
shares of BellSouth Corp.

The performance of the fixed income portfolio was influenced by our duration
profile, yield curve strategy and sector allocation decisions. We actively
adjusted the portfolio's duration profile throughout the year based on our
assessment of interest rate direction, with mixed results. In terms of specific
fixed income sectors, our underweight position in corporate bonds and mortgages,
coupled with an overweight in structured products for much of the year,
benefited performance.

What changes were made to the Portfolio during the period?

We continued to adjust our holdings over the year in response to ongoing market
volatility. Within the equity portfolio, we further repositioned our technology
holdings, reducing positions in Cisco Systems, Applied Materials, Inc. and
Microsoft Corp., eliminating Commscope, Citrix Systems, Inc. and Intel, adding
to existing positions in Hewlett-Packard Co., Electronic Arts, Inc. and Symantec
Corp., and introducing


                                       2


Juniper Networks, Inc., Sun Microsystems, Inc. and Yahoo! Inc. to the Portfolio.
We reduced the size of our Cisco holding after a 60% gain in 2006 and sold our
position in CommScope after a near-doubling in the stock price over the past 24
months. We trimmed our holding in Applied Materials based on our expectation for
a near-term peak in the company's pace of order activity. We sold Intel due to
its weakening competitive position and deteriorating profit margins. At
Hewlett-Packard, fundamentals continue to improve while valuation remains very
attractive. Juniper declined 20% on the day of the company's fourth-quarter
earnings announcement, affording us an attractive buying opportunity. Sun has
spent the better part of five years reengineering its core product line and is
now poised to regain market share and reverse a multiyear profit drought. At
video game manufacturer Electronic Arts, we are attracted by the company's No. 1
market share position and the recent video game console upgrade cycle as
Microsoft, Sony and Nintendo have all launched next-generation platforms.
Finally, we believe Yahoo! represents an attractive value after a 35% stock
price decline, as it affords us a reasonably priced way to invest in the rapid
growth of Internet advertising.

In other sectors, we established more substantial positions in two reinsurance
companies, Endurance Specialty Holdings Ltd. and RenaissanceRe Holdings Ltd., as
the market outlook for property and casualty insurers improved dramatically over
the past year. We trimmed exposure to the media sector, reducing our position in
Walt Disney Co. while eliminating Interpublic Group of Cos., Inc. and Viacom,
Inc. from the Portfolio. The long-awaited turnaround for global advertising
agency Interpublic Group continues to be reduced in magnitude and delayed in
timing, suggesting that significant progress is unlikely to occur within a
reasonable investment time horizon. At Viacom, the sudden firing of the CEO
prompted us to revaluate our investment position. We reduced our position in
Raytheon Co. and eliminated Northrop Grumman Corp. from the Portfolio on concern
about a slowing pace of defense budget growth and increasing pressures on
program pricing. We sold our position in Sara Lee Corp. and reinvested the
proceeds to expand existing positions in Unilever NV and Cadbury Schweppes Plc,
where we believe fundamental trends are more robust. We added to selected
industrial holdings like Textron, Inc. and 3M Co. on weakness, as we believe
their stock prices fail to capture these companies' favorable prospects.

A new management team assumed responsibility for the fixed income portfolio in
the fourth quarter and, at that time, shifted the portfolio's duration from long
to short versus the benchmark. This is consistent with the team's view that the
Fed is likely to remain on hold rather than cut interest rates as markets had
been anticipating. Also in the fixed income portfolio, exposure to spread
sectors was refined throughout the year in an effort to enhance portfolio yield
without incurring excessive risk. For the most part, high-quality spread
sectors, particularly commercial mortgage-backed securities and asset-backed
securities, were favored.

How would you characterize the Portfolio's position at the close of the period?

At year-end, 61.6% of the Portfolio's net assets was invested in equities, 31.5%
in fixed income securities and 6.9% in cash equivalents. While we continue to
anticipate a constructive environment for equities, we are increasingly
concerned that the recent sharp gain in the market has more than amply
discounted expectations for slower economic growth, declining inflation, stable
interest rates and continued strong corporate earnings. Should any of these
conditions fail to be met, however, much of the recent advance could be unwound.
With this in mind, we continue to tread cautiously, concentrating on limiting
our downside risks while being opportunistic on stocks that meet our fundamental
and valuation criteria. Meanwhile, as we have seen interest rates decline, the
yield curve invert and spreads compress, bonds have become a relatively less
attractive investment alternative. As always, we will continue to take full
advantage of the Portfolio's flexibility as market conditions evolve.

================================================================================
BlackRock Bond Portfolio
================================================================================

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock Bond Portfolio
(formerly Mercury Core Bond Strategy Portfolio) had a total return of +4.37%.
For the same period, the benchmark Lehman Brothers Aggregate Bond Index returned
+4.33%.

The yield curve was inverted for most of 2006. At the beginning of the year, the
10-year U.S. Treasury note yield stood at 4.39%, two basis points (.02%) below
the 4.41% yield on the two-year Treasury note. At the end of December, the 10-
and two-year Treasuries yielded 4.71% and 4.82%, respectively. Short-term
interest rates were volatile during the period, rising rather steadily between
January and June 2006 before declining through most of the remainder of the
year. The yield on the two-year note peaked at 5.29% in late June 2006, and then
dipped to a low of 4.52% in early December. The 10-year Treasury yield reached a
high of 5.25% late in the second quarter of 2006 before falling to a low of
4.43% in early December.

The Federal Reserve Board (the Fed) raised the target federal funds rate in five
increments of .25% during the year, bringing the target rate from 4.00% to
5.25%. However, the Fed held the rate steady at its meetings in August,
September, October and December. Gross domestic product (GDP) in the U.S. grew
at a rate of 2.0% in the third quarter of 2006. This represented a downturn from
the 2.6% growth rate for the second quarter of the year, and was considerably
lower than the 5.6% rate for the first quarter.

The Portfolio's performance was influenced by our duration profile, yield curve
strategy and sector allocation decisions. In the first quarter of the year, we
had positioned the Portfolio for a flattening yield curve, expressed largely
through an underexposure to the two- to five-year part of the curve and an
above-average position in the 30-year area. Because bond prices move in the
opposite direction of yields, our strategy paid off as short-term yields rose
more than long-term yields. That effect reversed in March as the yield curve
began to resteepen, and we took the opportunity to begin moving away from our
flattening bias.

Similarly, we began the fiscal year with a relatively short duration but started
to minimize that bias somewhat as the Fed approached its desired "neutral"
federal funds target. By mid-year, the Portfolio was positioned with a slightly
long duration, a posture we assumed as the 10-year Treasury yield approached
5.25%. Our increasing duration hurt performance at times when interest rates
rose (as a shorter duration means less sensitivity to interest rate risk, and
vice versa). However, our longer relative duration was a positive in the third
quarter as yields began to move lower. The Portfolio's new management team
shifted to a shorter duration in the fourth quarter, and this had a modest
positive effect on performance as rates moved marginally higher, reversing a
portion of the significant rally experienced in the third quarter.

In terms of specific fixed income sectors, we maintained a neutral to slightly
underweight position in corporate bonds and mortgages for much of the year, a
strategy that benefited performance when credit spreads widened but detracted
when spreads tightened. Conversely, we overweighted high-quality short-duration
assets, including asset-backed securities (ABS), commercial mortgage-backed
securities


                                       4


(CMBS), adjustable rate mortgages (ARMs) and collateralized mortgage obligations
(CMOs). This enhanced performance during the year, as these sectors offered an
incremental yield advantage over Treasury issues.

What changes were made to the Portfolio during the period?

We actively adjusted the Portfolio's duration profile based on our assessment of
interest rate direction. We began the year with a relatively short duration. In
March, the Treasury curve steepened by 20 basis points between the two- and
30-year sectors. This was a dramatic one-month move considering the flatness of
the curve, and served to support the short end as the long end normalized. This
prompted us to remove some of our curve flattening bias and to move from a short
duration bias toward a more neutral duration profile. By the second quarter of
2006, as long-term interest rates continued to rise, the Portfolio's duration
was slightly longer than that of the benchmark index. In our view, the 10-year
U.S. Treasury began to represent value as its yield approached 5.25%.

A new management team assumed responsibility for the Portfolio in the fourth
quarter and, at that time, shifted the Portfolio's duration from long to short
versus the benchmark. This was consistent with the team's view that the Fed is
likely to remain on hold, not cut interest rates as markets have priced in.

Turning to sectors, the Portfolio was underweight in corporate bonds for much of
the year as credit spreads remained tight, meaning there was little additional
yield to be gained in exchange for the risk involved. The new management team
reduced exposure to corporate bonds in the fourth quarter based on the belief
that event risk remains high, valuations are unattractive and fundamentals
appear to have peaked. In addition, a small currency position in the Japanese
yen was established in the final three months of the fiscal year.

For the most part, we continued to favor high-quality spread sectors throughout
the year for their yield-enhancement potential.

How would you characterize the Portfolio's position at the close of the period?

At December 31, 2006, the Portfolio was underweight in U.S. Treasury issues,
U.S. agency securities and corporate securities. The Portfolio held notable
overweights in high-quality, short-duration spread product, including CMBS and
ABS issues. The Portfolio also ended the fiscal year with an above-average
exposure to mortgages, specifically in the 15-year and non-index sectors,
including ARMs and CMOs.

The Portfolio is positioned with a short duration versus the benchmark, as we
continue to believe that both a modest rebound in economic growth during the
fourth quarter and core inflation remaining outside of the Fed's comfort zone
will keep the central bank on hold.

================================================================================
BlackRock Fundamental Growth Portfolio
================================================================================

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock Fundamental Growth
Portfolio (formerly Mercury Fundamental Growth Strategy Portfolio) posted a
total return of +4.78%. For the same period, the benchmark S&P 500 Citigroup
Growth Index returned +11.00% and the Lipper Large-Cap Growth Funds (Variable
Products) category had an average return of +4.68%. (Funds in this Lipper
category invest at least 75% of their equity assets in companies with market
capitalizations -- on a three-year weighted basis -- greater than 300% of the
dollar-weighted median market capitalization of the middle 1,000 securities of
the S&P SuperComposite 1500 Index. Large-cap growth funds typically have an
above-average price-to-earnings ratio, price-to-book ratio, and three-year
sales-per-share growth value, compared to the S&P 500 Index.) The broad U.S.
equity market, as measured by the S&P 500 Index, returned +15.79% over the
12-month period.

During 2006, equity markets experienced varied returns that were significantly
influenced by shifting investor preferences. Market leadership at the end of
December was distinctly different from that seen in January and mid-year. A
widely anticipated market correction during the May to July timeframe (which
amounted to a nearly 8% retrenchment for the S&P 500 Index) segmented the year
in terms of both style and sector performance considerations. Small and
mid-sized companies dominated performance during the first five months of the
year before giving way to larger companies after the market correction took
place. The value style of investing continued to outperform the growth style for
the majority of the 12-month period. Larger-capitalization growth companies only
started to outperform late in the year, but lagged the broader market for all of
2006.

In general, actively managed funds struggled, especially in the second half of
the year, as reflected in the underperformance of the Lipper Large-Cap Growth
Funds category versus the largely market-weighted S&P 500 Citigroup Growth
Index. From a sector perspective, a cyclical bias favored energy, materials and
industrials-related sectors in the early portion of the year, whereas a clearly
more defensive posture prevailed later in the period. Much of this transition in
the market could be attributed to concerns over the rate of slowdown in U.S.
economic growth and the Federal Reserve Board's (the Fed's) intentions with
regard to monetary policy.

The Portfolio's performance for the year was negatively impacted by these market
transitions. Favorable performance in the first half of the year proved more
difficult to repeat in the second half. Our overweight position in the energy
sector and underweight position in information technology (IT), which
contributed to performance in the first half, remained positive contributors
until the third quarter. Offsetting this was poor stock selection in the second
half of the year in the health care, energy and information technology sectors.
Specialty pharmaceutical company Alcon, Inc. and health care services providers
Medco Health Solutions, Inc., WellPoint Inc. and UnitedHealth Group, Inc.
detracted from performance. Within the IT sector, Yahoo!, Inc., Corning, Inc.
and Oracle Corp. all detracted from performance, as did the absence of a
position in Cisco Systems, Inc. for most of the year and our avoidance of
Microsoft Corp. and


                                       6


International Business Machines Corp. At the same time, Portfolio holdings in IT
outsourcing companies Infosys Technologies Ltd. and Cognizent Technology
Solutions Corp., as well as oil service companies Schlumberger Ltd. and Baker
Hughes, Inc., contributed positively to performance.

What changes were made to the Portfolio during the period?

In the second half of 2006, we repositioned the Portfolio to adjust to a more
moderate rate of economic growth in the United States. To that end, we reduced
our energy overweight to a slight underweight and increased IT from a
significant underweight to a modest overweight position. We also trimmed our
overweighting in industrials. We exited the managed-care industry, thereby
reducing our overall sector exposure to the health care sector. Meanwhile, we
increased the Portfolio's exposure to the consumer discretionary and financials
sectors, particularly in retail and capital markets-related companies,
respectively.

Notable additions to the Portfolio during the year included Cisco Systems, Inc.,
American International Group, Inc. Genentech, Inc., The Charles Schwab Corp.,
Corning, Inc., QUALCOMM, Inc., Target Corp., Novartis AG, Emerson Electric Co.
and Thermo Fisher Scientific, Inc. Noteworthy sales included Exxon Mobil Corp,
3M Co., Wellpoint, Inc., UnitedHealth Group, Inc., The Dow Chemical Co.,
Medtronic Inc., eBay Inc. and Boeing Co. In addition, our positions in The
Procter & Gamble Co. and Alcon, Inc. were considerably reduced, but not
eliminated from the Portfolio.

How would you characterize the Portfolio's position at the close of the period?

U.S. economic growth (that is, gross domestic product growth) has slowed to a
slightly below-trend rate of expansion (in the area of 2%-3%). We view this as a
typical mid-cycle slowdown. At the same time, most other global economies,
particularly those in Europe and Asia, continue to experience strong rates of
growth. This provides a rather balanced demand backdrop worldwide, which is an
important consideration given that many of the Portfolio's investments are
multinational companies that depend upon the health of the global economy. We do
not expect a recession to unfold in the United States and, in fact, suspect
there is upside risk to accelerating economic growth by year-end 2007. It
appears as if inflationary expectations have been well contained via adequate
Fed policy initiatives. Although this mid-cycle slowdown may challenge broader
market earnings growth over the near term, it should provide an attractive
investment environment for growth stocks going forward.

The Portfolio ended the period overweight in the consumer discretionary,
information technology, financials and industrials sectors and underweight in
consumer staples, health care and energy.

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock Global Allocation
Portfolio (formerly Mercury Global Allocation Strategy Portfolio) had a total
return of +16.89%. Portfolio results exceeded the +13.74% return of its
Reference Portfolio for the 12-month period, but trailed the +21.46% return of
its broad-based, all-equity benchmark, the Financial Times Stock Exchange (FTSE)
World Index.

The Portfolio invests in a combination of equities and bonds; therefore, the
Reference Portfolio provides both a truer representation of the Portfolio's
composition and a more comparable means for measurement. Returns for each
component of the Reference Portfolio for the 12 months ended December 31, 2006,
were as follows: the Standard & Poor's 500 (S&P 500) Index returned +15.79%; the
FTSE World Index (ex-U.S.) returned +26.98%; the Merrill Lynch Treasury Index
GA05 returned +2.81%; and the Citigroup World Government Bond Index (ex-U.S.)
returned +6.94%. (A full description of the Reference Portfolio can be found on
page 22 of this report to shareholders.)


                                       7


The Portfolio outperformed its comparable Lipper category of Global Flexible
Portfolio Portfolios (Variable Products), which posted an average return of
+15.56% for the 12-month period. (As defined by Lipper, funds in this Lipper
category allocate their investments across various asset classes, including both
domestic and foreign stocks, bonds and money market instruments, and focus on
total return.)

While U.S. stocks, as measured by the S&P 500 Index, returned +15.79% for the
year, the MSCI Europe Index and the MSCI Pacific Index gained 33.72% and 12.20%,
respectively, in U.S. dollar terms. The Federal Reserve Board's (the Fed)
decision to pause its monetary tightening campaign, along with double-digit
corporate earnings growth that largely surprised investors, helped push U.S.
stocks higher during the period. European equities rose even more dramatically,
propelled by stronger-than-expected company fundamentals, improved business and
consumer sentiment (particularly in Germany and France), as well as a record
pace of merger-and-acquisition activity. This helped ratchet up various country
indexes, such as Spain's IBEX 35, which surged 51.72% for the year. Notably, the
euro strengthened 11.40% versus the U.S. dollar during the 12-month period,
further improving the returns for European assets.

In the Pacific region, strong earnings growth and benign regional central bank
policy proved a favorable combination for equities. India's Sensex Index
remained one of the world's leading equity markets, advancing 49.30% for the
12-month period. Other strong performers were Indonesia (+73.68%), Singapore
(+47.95%) and Australia (+35.18%). Nearly all major Pacific Basin currencies
appreciated against the U.S. dollar during the period, with the exception of the
Japanese yen (down 1.1%). Importantly, Japan's Nikkei, which posted a +6.91%
annual return, was a laggard relative to most other Asia/Pacific equity markets.
Although the Japanese equity market benefited from positive investor sentiment
that was characteristic of the period, some concerns have arisen about the
Japanese manufacturing sector and the country's export prospects have weighed on
returns recently.

On the fixed income side, five-year U.S. Treasury issues gained 2.81% and
10-year U.S. Treasury issues were up 1.36% over the 12-month period. Although
somewhat concerned about inflationary U.S. labor costs, which could depress
corporate profits, most fixed income investors were encouraged by the Fed's
pause in interest rate hikes and the increasing prospects of a slowing U.S.
economy as we neared 2007. International bond prices generally declined in local
currency terms. In Europe, yields on German bunds and U.K. gilts increased 64
basis points (.64%) and 70 basis points, respectively, as concern about rising
interest rates from both the European Central Bank and the Bank of England
weighed on the minds of bond investors. In Japan, 10-year government bonds fell
modestly as yields increased from 1.48% to 1.69%. The Bank of Japan ended its
long-standing "quantitative easing" policy during the year and signaled that if
deflationary pressures remain at bay, higher overnight lending rates could be in
store for 2007.

What factors most influenced Portfolio performance during the period?

The Portfolio was able to capitalize on favorable equity performance in most
developed markets around the world. At the start of the period, the Portfolio's
asset allocation strategy included a relatively slight overweight in equities
and a significant underweight in fixed income securities, particularly
high-quality, long-term U.S. government bonds. The Portfolio benefited from a
significant overweight exposure to Asian equities, notably in India and
Singapore, and favorable stock selection in the United States. Effective
security selection in the energy, industrials and information technology sectors
also boosted performance as oil prices continued their ascent (26%) to a high
near $78 per barrel in July before receding to roughly $61 per barrel by the end
of December, remaining relatively unchanged year over year. In addition, growth
in Asia, notably in China, continued to fuel demand for raw materials,
particularly energy resources, and capital investment in energy-related
production. Detracting from the Portfolio's relative results was its underweight
position in European equities, particularly in Spain, as these markets
appreciated significantly during the year.

Although considerably underweight in fixed income, the Portfolio continued to
benefit from the makeup of its fixed income component. This included a modest
exposure to high yield issues, including U.S. corporate bonds and convertible
securities, and emerging markets debt. The Portfolio maintained its underweight
position in non-U.S.-dollar sovereign debt (notably in Japan), as yields
remained unattractive.


                                       8


What changes were made to the Portfolio during the period?

The Reference Portfolio comprises 60% equities and 40% fixed income securities.
Within our Portfolio, we reduced the total equity allocation from 61% of net
assets to 55%, primarily by decreasing exposure to U.S. and Japanese equities.
This was partially offset by an increase in European and Brazilian equities. We
believe corporate earnings growth rates in the United States will slow and the
sustainability of consumer spending will abate. Our strategy included reducing
the cyclicality of the equity portfolio and taking profits in stocks that had
significantly appreciated, notably in the strong-performing materials and energy
sectors.

Whereas the Portfolio was significantly underweight in fixed income securities
throughout the fiscal year, we did boost our exposure from 22% of net assets to
approximately 32% by period-end with a greater allocation to U.S. Treasury
Inflation Protected Securities (TIPS). (We note that the Portfolio's U.S. fixed
income exposure includes bonds of non-U.S. issuers denominated in U.S. dollars.)
Approximately 3.2% of the Portfolio's net assets was invested in convertible
securities as of December 31, 2006. These securities are reported as a portion
of the Portfolio's fixed income allocation, although some of these securities
may tend to perform similar to equities. Given the aforementioned changes, the
Portfolio's position in cash equivalent securities decreased from 17% of net
assets to 13% over the 12-month period. Cash is actively managed and, as such,
allocations to cash are an integral part of the Portfolio's investment strategy.
Currently, cash is considered zero-duration fixed income and includes short-term
U.S. dollar and non-U.S. dollar fixed income securities and other money
market-type instruments.

How would you characterize the Portfolio's position at the close of the period?

Broadly speaking, compared to its Reference Portfolio, the Portfolio closed the
fiscal year underweight in equities and non-U.S. fixed income securities, and
overweight in cash reserves.

Within the equity segment, the Portfolio was significantly underweight in the
United States, overweight in Asia, and relatively neutral in Europe. From a
sector perspective, the Portfolio was overweight in telecommunications,
industrials, energy and materials; underweight in consumer discretionary,
technology, health care, consumer staples and financials; and relatively neutral
in utilities. The Portfolio's underweight fixed income exposure reflects the
assessment that available yields are insufficiently attractive relative to the
risks of higher inflation and higher interest rates, especially outside the
United States. With respect to currency, we ended the annual period with
underweight positions in the U.S. dollar, Japanese yen and British pound
sterling, a relatively neutral position in the euro, and slightly overweight
positions in the Brazilian real and several Asian currencies.

The Portfolio's equity allocation at year-end -- although underweight relative
to our Reference Portfolio -- was still higher than during most of the
Portfolio's history. Accordingly, we expect that the Portfolio may exhibit a
somewhat higher beta versus the S&P 500 Index and higher volatility in net asset
value than historically has been the case. Nevertheless, given the Portfolio's
current posture, we believe both of these measures should remain below those
typical of most all-equity funds in most market conditions.

BlackRock Government Income Portfolio
================================================================================

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock Government Income
Portfolio (formerly Mercury Intermediate Government Bond Portfolio) had a total
return of +4.10%. For the same period, the benchmark Citigroup
Government/Mortgage Index returned +4.26%.


                                       9


Short-term interest rates, which rose steadily between January and June,
declined for most of the remainder of 2006 before backing up sharply in
December. Bond prices move in the opposite direction of yields and, as such,
this meant that the latter half of the fiscal year was generally characterized
by a return to strength for fixed income assets. The improvement in bond prices
came amid a slowdown in U.S. economic growth and the Federal Reserve Board's
(the Fed's) decision at its August 8 meeting to refrain from raising its target
rate after 17 consecutive increases since June 2004. Bond prices found
additional support in moderating oil prices. Between June 30 and November 30,
10-year Treasury yields declined 69 basis points (.69%) from 5.15% to 4.46%.
However, stronger-than-expected economic releases and year-end profit taking
pushed yields higher during December.

For the 12-month period overall, 10-year Treasury note yields rose 32 basis
points to 4.71% and two-year Treasury yields rose 34 basis points to 4.82%.
These yields reflect the inverted shape of the yield curve at year-end. In fact,
for much of 2006, short-term issues had higher yields than longer-term bonds.

In terms of Portfolio performance, our emphasis on the Government National
Mortgage Association (GNMA) project loan sector was a positive contributor.
Given limited issuance, along with a growing investor base and strong demand,
yield spreads on these securities (versus Treasury issues of comparable
maturity) narrowed to their all-time tightest level. This allowed the project
loan sector to generate excess return compared to Treasury securities. Also
contributing positively to performance was our use of total return swaps on the
mortgage-backed securities (MBS) and Treasury indexes. We used this strategy in
conjunction with floating rate London Interbank Offered Rate (LIBOR)
investments, which resulted in total return advantages above those indexes
alone. In a total rate of return swap, we agree to receive the total return of a
particular index while paying the total return of one-month LIBOR. At the same
time, we purchase conservative floating rate LIBOR investments at a spread over
LIBOR. By doing this, we are able to generate a total return profile above and
beyond the index return.

The Portfolio's relatively long duration stance detracted from performance in
the first half of the year as interest rates rose, but provided advantageous in
the third quarter as the market rallied and yields fell. A new management team
assumed responsibility for the portfolio in the fourth quarter and, at that
time, shifted the Portfolio's duration from long to short versus the benchmark.
This was consistent with the team's view that the Fed is likely to remain on
hold, not cut interest rates as markets have priced in, and contributed to
performance as rates moved marginally higher toward year-end.

Finally, our underweighting in MBS hindered relative results as robust demand
from banks caused MBS yield spreads to narrow. This allowed MBS to generate
strong relative performance versus U.S. Treasury securities during the period.
Mortgages were one of the strongest-performing sectors of the fixed income
market for the year.

What changes were made to the Portfolio during the period?

As we continued to benefit from the strong performance of the GNMA project loan
sector, we trimmed our holdings to capture gains. In addition, we increased the
Portfolio's holdings of MBS given the attractive yields available and our belief
that the sector would perform well on a relative basis once the Fed ended its
interest rate-hiking campaign. We felt a break in monetary tightening would
create a more range-bound interest rate environment. Such an environment means
reduced prepayment volatility, lessening MBS duration extension and contraction
risk and thereby creating a positive backdrop for the MBS market. We also added
some exposure to 10-year agency debentures when the sector had become
inexpensive.

As mentioned previously, the new management team reduced duration in the fourth
quarter and also increased the Portfolio's allocation to mortgage issues over
agency issues. Within mortgages, the Portfolio favored 15-year maturities over
30-year maturities and maintained a bias toward higher-coupon mortgage issues.

How would you characterize the Portfolio's position at the close of the period?

At year-end, the Portfolio remained underweight in U.S. agency securities, in
favor of Treasury issues, mortgages and high-quality, short-duration spread
product, including commercial mortgage-backed


                                       10


securities (CMBS), adjustable-rate mortgages and collateralized mortgage
obligations (CMOs). We maintained our preference for high-coupon and 15-year
mortgages over lower-coupon and 30-year mortgages.

At period-end, the Portfolio's primary sector exposures were broken out at
follows: 26% U.S. Treasury securities, 38% pass-through mortgages, 28% CMOs and
4% CMBS. This compared to the Citigroup Government/Mortgage Index's composition
of 37% U.S. Treasury securities, 13% U.S. agency securities and 50% MBS.

================================================================================
BlackRock High Income Portfolio
================================================================================

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock High Income Portfolio
(formerly Mercury High Yield Portfolio) had a total return of +8.98%. For the
same period, the benchmark Credit Suisse High Yield Index returned +11.92% and
the Lipper High Current Yield Funds (Variable Products) category had an average
return of +9.09%. (Funds in this Lipper category seek high relative current
yield from fixed income securities, have no quality or maturity restrictions,
and tend to invest in lower-grade debt issues.)

The yield curve was inverted for most of 2006. At the beginning of the year, the
10-year U.S. Treasury note yield stood at 4.39%, two basis points (.02%) below
the 4.41% yield on the two-year Treasury note. At the end of December, the 10-
and two-year Treasuries yielded 4.71% and 4.82%, respectively. Short-term
interest rates were volatile during the period, rising rather steadily between
January and June 2006 before declining through most of the remainder of the
year. The yield on the two-year note peaked at 5.29% in late June 2006, and then
dipped to a low of 4.52% in early December. The 10-year Treasury yield reached a
high of 5.25% late in the second quarter of 2006 before falling to a low of
4.43% in early December.

The Federal Reserve Board (the Fed) raised the target federal funds rate in five
increments of .25% during the year, bringing the target rate from 4.00% to
5.25%. However, the Fed held the rate steady at its meetings in August,
September, October and December.

The high yield market's nearly 12% return for the year was well ahead of the
+4.33% return of the U.S. investment-grade bond market, as measured by the
Lehman Brothers Aggregate Bond Index. The high yield market generally moved
upward, although it did encounter weakness in June. The extent of the market's
decline, however, was not as intense as that experienced by other asset classes
in the middle of 2006. Global equities and emerging markets securities fell
markedly in May. However, the high yield market found support in benign default
rates and lower sensitivity to rising interest rates and, therefore, experienced
less volatility than other equity and fixed income asset classes.

What factors most influenced Portfolio performance?

The Portfolio's relatively conservative positioning hindered performance
somewhat, as lower-quality, longer-duration securities outperformed the broader
market during the year. Other detractors included an


                                       11


overweight in the housing sector, which has been plagued by weakening
fundamentals, and an underweight in autos as General Motors Corp.'s bonds, a
large complex of securities, rallied strongly. On the positive side of the
ledger, we saw good results from our holdings in the manufacturing, media --
non-cable, paper and chemicals sectors.

What changes were made to the Portfolio during the period?

We sold some of our holdings in packaging, which resulted in a reduction in that
sector from an overweight to a market weight. We were concerned about the high
cost of resin, a key factor affecting the profitability of plastic packaging
manufacturers. Meanwhile, we increased exposure to the chemicals sector, moving
from a market weight to an overweight in the third quarter. In a contrarian
move, we bought several bonds in the out-of-favor homebuilder and building
products manufacturer sectors, mostly in the secondary market.

In the final quarter of the year, the Portfolio's new management team increased
allocations to certain lower-quality credit tiers, establishing overweight
positions in B-rated and CCC-rated credits. This was done in an effort to
capitalize on positive returns being generated by these segments of the high
yield market. The Portfolio's position in the automobile sector also was
increased, bringing the allocation from an underweight to a modest overweight
relative to the benchmark.

How would you characterize the Portfolio's position at the close of the period?

At December 31, 2006, the Portfolio had overweight positions in the wireless,
paper, technology and independent energy sectors. Conversely, it had noticeable
underweight positions in the electric, media -- cable, supermarkets and lodging
sectors.

We believe the Portfolio is well positioned to take advantage of opportunities
in the high yield market in 2007. The Portfolio had an average credit rating of
B+ at year-end, and we believe our disciplined yet flexible approach positions
the Portfolio to benefit from the potential outperformance of lower-quality
names while limiting credit and default risk.

================================================================================
BlackRock Large Cap Core Portfolio
================================================================================

How did the Portfolio perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended December 31, 2006, BlackRock Large Cap Core
Portfolio (formerly Mercury Large Cap Core Strategy Portfolio) returned +15.06%,
slightly behind the +15.46% return of the benchmark Russell 1000 Index.
Portfolio results exceeded the +11.78% average return of the Lipper Multi-Cap
Core Funds (Variable Products) category for the same period. (Funds in this
Lipper category invest in a variety of market-capitalization ranges without
concentrating 75% of their equity assets in any one


                                       12


market-capitalization range over an extended period of time. Multi-Cap Core
funds typically have an average price-to-earnings ratio, price-to-book ratio and
three-year sales-per-share growth value compared to the S&P SuperComposite 1500
Index.)

The Portfolio invests primarily in a diversified portfolio of large cap
companies selected from securities found in the Russell 1000 Index. Successful
stock selection contributed positively to returns within the materials sector,
led by shares of metals and mining holdings NuCor and Phelps Dodge Corp. In the
industrials sector, strong performance came from aerospace/defense company
Lockheed Martin Corp., and in the consumer discretionary sector, cable
television provider The DirectTV Group, Inc. and retailer JCPenney Co., Inc.
were both significant contributors to performance. The Portfolio benefited from
an overweight position in the energy sector and also from our avoidance of
Sprint Nextel Corp., a benchmark holding that fared poorly during the period. In
other sectors, individual holdings that contributed positively included
semiconductor company Nvidia Corp., networking giant Cisco Systems, Inc. and
computer equipment company Hewlett-Packard Co., all in information technology,
and Kerr-McGee Corp. and Marathon Oil Corp., both in the energy sector.

Positive results from successful stock selection in the financials and
information technology sectors were partially offset by the negative impact of
the Portfolio's overall allocations to these sectors (i.e., underweighting
financial and telecommunication service holdings and overweighting information
technology holdings). Stock selection and allocation decisions in health care
(overweight) and consumer staples (underweight) also hindered performance.
Individual stocks that detracted from performance during the fiscal period
included agricultural company Archer Daniels Midland Co., energy companies
Sunoco, Inc. and Frontier Oil Corp., and technology companies Advanced Micro
Devices, Inc., Dell, Inc., National Semiconductor Corp. and Apple Computer, Inc.

Because the Portfolio invests in large-capitalization stocks that represent a
significant part of the U.S. stock market, it was influenced by the same
economic and market events that affected the broader stock market during the
period. The year featured a slowdown in economic growth, a Federal Reserve Board
(the Fed) that finally paused in its rate-hiking campaign, renewed threats of
inflation and surprisingly strong corporate earnings. Amid these crosscurrents,
U.S. stock markets started 2006 on a good note, experienced their first
significant correction since 2002 and then recovered to end the year solidly in
the black. The market correction that began in May proved to be difficult for
the Portfolio. The market environment was challenging for cyclical stocks, and
the Portfolio lost ground due to its procyclical positioning. We made modest
adjustments to the Portfolio as a result, and relative performance did improve.

What changes were made to the Portfolio during the period?

Overall, we continued our efforts to identify companies with favorable growth
characteristics and earnings developments, selling at attractive relative
valuations. As a result of our bottom-up stock-selection process, we increased
the Fund's position in the consumer discretionary sector and reduced exposure to
the information technology, energy, health care, industrials, materials and
utilities sectors.

The largest purchases during the period, based on capital expended, included
JPMorgan Chase & Co., Johnson & Johnson, International Business Machines Corp.,
Citigroup, Inc. and Merck & Co, Inc. The largest sales, based on capital raised,
included ConocoPhillips, Intel Corp., Amgen, Inc., Boeing Co. and The Coca-Cola
Co. These transactions reflect our ongoing refinement of the Portfolio, as we
continue to look for stocks that best meet our investment criteria while pruning
those that have deteriorated versus our original assessment.

How would you characterize the Portfolio's position at the close of the period?

We believe the U.S. economy remains on track for a soft landing, while growth
outside the United States remains reasonably strong. The housing-related growth
slowdown, coupled with a continued easing of inflation pressures, should permit
the Fed to lower interest rates some time around mid-year. Corporate profits
should move up thanks in part to non-U.S. economic strength, but the rate of
gain is expected to slow noticeably, as record-high profit margins will be
difficult to sustain.


                                       13


In our opinion, equities should enjoy another year of good returns in 2007.
Assuming a soft landing, investors may be willing to extend time horizons,
permitting some upward valuation of mildly rising earnings. The key will be for
inflation expectations to remain well behaved. The environment should provide a
constructive liquidity backdrop, encouraging continued dividend increases, stock
buy-backs and merger-and-acquisition activity. As U.S. growth slows and interest
rate differentials work against the U.S. (that is, the Fed contemplates cutting
rates while foreign central banks raise rates), the path of least resistance for
the dollar is down, hopefully in a gradual way.

2007 will likely feature continued rotation away from domestic growth and the
consumer toward business fixed investments, exports and other sources of
non-U.S. growth. Therefore, in another year where security selection will be
critical, we prefer companies with exposure to foreign sales, those that have
the ability to increase dividends, and those that are generally larger and of
higher quality. We have a particularly constructive view of the energy, health
care and information technology sectors. As of December 31, 2006, the
Portfolio's largest overweights relative to the benchmark were in information
technology, energy, health care and consumer discretionary, and the largest
underweights were in financials, industrials, utilities, consumer staples and
telecommunication services.

BlackRock Series Fund, Inc.
Disclosure of Expenses
================================================================================

Shareholders of each Portfolio may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and exchange
fees; and (b) operating expenses including advisory fees and other Portfolio
expenses. The following example (which is based on a hypothetical investment of
$1,000 invested on July 1, 2006 and held through December 31, 2006) is intended
to assist shareholders both in calculating expenses based on an investment in
each Portfolio and in comparing these expenses with similar costs of investing
in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during the
period covered by this report, shareholders' can divide their account value by
$1,000 and then multiply the result by the number in the first line under the
heading entitled "Expenses Paid During the Period."

The second table below provides information about hypothetical account values
and hypothetical expenses based on each Portfolio's actual expense ratio and an
assumed rate of return of 5% per year before expenses. In order to assist
shareholders in comparing the ongoing expenses of investing in this Fund and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders' ongoing
costs only and do not reflect any transactional expenses, such as sales charges,
redemption fees or exchange fees. Therefore, the second table is useful in
comparing ongoing expenses only, and will not help shareholders determine the
relative total expenses of owning different funds. If these transactional
expenses were included, shareholder expenses would have been higher.

================================================================================

1. Significant Accounting Policies:

On September 29, 2006, FAM Series Fund, Inc. was renamed BlackRock Series Fund,
Inc. (the "Fund") and is registered under the Investment Company Act of 1940, as
amended, as an open-ended management investment company, offering fourteen
separate portfolios. This report relates to eight of the Fund's diversified
Portfolios (referred to as the "Portfolios" or individually as a "Portfolio").
On September 29, 2006, Mercury Balanced Capital Strategy Portfolio, Mercury Core
Bond Strategy Portfolio, Mercury Fundamental Growth Strategy Portfolio, Mercury
Global Allocation Strategy Portfolio, Mercury High Yield Portfolio, Mercury
Intermediate Government Bond Portfolio, Mercury Large Cap Core Strategy
Portfolio and Mercury Money Reserve Portfolio were renamed BlackRock Balanced
Capital Portfolio, BlackRock Bond Portfolio, BlackRock Fundamental Growth
Portfolio, BlackRock Global Allocation Portfolio, BlackRock High Income
Portfolio, BlackRock Government Income Portfolio, BlackRock Large Cap Core
Portfolio and BlackRock Money Market Portfolio, respectively. Each Portfolio is
classified as diversified under the Investment Company Act of 1940, as amended.
The Fund's financial statements are prepared in conformity with U.S. generally
accepted accounting principles, which may require the use of management accruals
and estimates. Actual results may differ from these estimates. The Fund offers
its shares to Merrill Lynch Life Insurance Company, ML Life Insurance Company of
New York (indirect, wholly-owned subsidiaries of Merrill Lynch & Co., Inc.
("Merrill Lynch")), and Monarch Life Insurance Company ("Monarch") (an insurance
company not affiliated with Merrill Lynch) for their separate accounts to fund
benefits under certain variable life insurance contracts. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--For the BlackRock Money Market Portfolio,
investments maturing more than 60 days after the valuation date are valued at
market value. When such securities are valued with 60 days or less 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.
Investments maturing within 60 days from their date of acquisition are valued at
amortized cost, which approximates market value. For the purpose of valuation,
the maturity of a variable rate certificate of deposit is deemed to be the next
coupon date on which the interest rate is to be adjusted.

BlackRock Balanced Capital Portfolio, BlackRock Bond Portfolio, BlackRock
Fundamental Growth Portfolio, BlackRock Global Allocation Portfolio, BlackRock
Government Income Portfolio, BlackRock High Income Portfolio and BlackRock Large
Cap Core Portfolio:

Debt securities are traded primarily in the over-the-counter ("OTC") markets and
are valued at the last available bid price in the OTC market or on the basis of
values obtained by a pricing service. Pricing services use valuation matrixes
that incorporate both dealer-supplied valuations and valuation models. The
procedures of the pricing service and its valuations are reviewed by the
officers of the Fund under the general direction of the Board of Directors. Such
valuations and procedures will be reviewed periodically by the Board of
Directors of the Fund. Financial futures contracts and options thereon, which
are traded on exchanges, are valued at their closing prices as of the close of
such exchanges. Options written or purchased are valued at the last sale price
in the case of exchange-traded options. Options traded in the OTC market are
valued at the last asked price (options written) or the last bid price (options
purchased). Swap agreements and structured notes are valued based upon quoted
fair valuations received daily by the Portfolio from a pricing service or
counterparty. Short-term investments with a remaining maturity of 60 days or
less are valued at amortized cost, which approximates market value, under which
method the investment is valued at cost and any premium or discount is amortized
on a straight line basis to maturity. Valuation of other short-term investment
vehicles is generally based on the net asset value of the underlying investment
vehicle or amortized cost. Repurchase agreements are valued at cost plus accrued
interest. Investments in open-end investment companies are valued at their net
asset value each business day. Securities and other 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 Fund.

BlackRock Series Fund, Inc.
Notes to Financial Statements (Continued)
================================================================================

Equity securities held by each Portfolio that are traded on stock exchanges or
the NASDAQ Global Market are valued at the last sale price or official close
price on the exchange, as of the close of business on the day the securities are
being valued or, lacking any sales, at the last available bid price for long
positions, and at the last available asked price for short positions. In cases
where equity securities are traded on more than one exchange, the securities are
valued on the exchange designated as the primary market by or under the
authority of the Board of Directors of the Fund. Long positions traded in the
OTC markets, NASDAQ Capital Market or Bulletin Board are valued at the last
available bid price or yield equivalent obtained from one or more dealers or
pricing services approved by the Board of Directors of the Fund. Short positions
traded in the OTC markets are valued at the last available asked price.
Portfolio securities that are traded both in the OTC markets and on a stock
exchange are valued according to the broadest and most representative market.

Generally, trading in foreign securities, as well as U.S. government securities,
money market instruments and certain fixed income securities, is substantially
completed each day at various times prior to the close of business on the New
York Stock Exchange ("NYSE"). The values of such securities used in computing
the net asset value of the Portfolios' shares are determined as of such times.
Foreign currency exchange rates will generally be determined as of the close of
business on the NYSE. Occasionally, events affecting the values of such
securities and such exchange rates may occur between the times at which they are
determined and the close of business on the NYSE that may not be reflected in
the computation of the Portfolios' net asset value. If events (for example, a
company announcement, market volatility or a natural disaster) occur during such
periods that are expected to materially affect the value of such securities,
those securities will be valued at their fair value as determined in good faith
by the Fund's Board of Directors or by BlackRock Advisors, LLC (the "Manager"),
an indirect, wholly owned subsidiary of BlackRock, Inc., using a pricing service
and/or procedures approved by the Fund's Board of Directors.

(b) Repurchase agreements--Certain Portfolios may invest in U.S. 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 Portfolio takes possession of the underlying securities,
marks-to-market such securities and, if necessary, receives additional
securities daily to ensure that the contract is fully collateralized. If the
counterparty defaults and the fair value of the collateral declines, liquidation
of the collateral by the Portfolios may be delayed or limited.

(c) Reverse repurchase agreements--Certain Portfolios may enter into reverse
repurchase agreements. Under reverse repurchase agreements, the Portfolio sells
securities to the counterparty and agrees to repurchase them at a mutually
agreed upon date and price, and may exchange their respective commitments to pay
or receive interest. If the counterparty defaults on its obligation, the
Portfolio's ability to receive interest will be delayed or limited. Furthermore,
if the Portfolio does not have sufficient income to pay its obligation under the
reverse repurchase agreement, the Portfolio would be in default and the
counterparty would be able to terminate the repurchase agreement.

(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).
Realized gains and losses on security transactions are determined on the
identified cost basis. 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 Portfolios have determined the ex-dividend date.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(f) Prepaid registration fees--Prepaid registration fees are charged to expense
as the related shares are issued.

Notes to Financial Statements (Continued)
================================================================================

(g) Derivative financial instruments--Certain Portfolios may engage in various
portfolio investment strategies both to increase the return of the Portfolio and
to hedge, or protect, its exposure to interest rate movements and movements in
securities markets. Losses may arise due to changes in the value of the contract
due to an unfavorable change in the price of the underlying security or index,
or if the counterparty does not perform under the contract.

o Foreign currency options and futures--Certain Portfolios may also purchase or
sell listed or OTC 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-U.S. dollar-denominated securities owned by the
Portfolio, sold by the Portfolio but not yet delivered, or committed or
anticipated to be purchased by the Portfolio.

o Forward foreign exchange contracts--Certain Portfolios may enter into forward
foreign exchange contracts as a hedge against either specific transactions or
portfolio positions. The contract is marked-to-market daily and the change in
market value is recorded by the Portfolio as an unrealized gain or loss. When
the contract is closed, the Portfolio records a realized gain or loss equal to
the difference between the value at the time it was opened and the value at the
time it was closed.

o Options--Certain Portfolios may write and purchase call and put options. When
a Portfolio writes an option, an amount equal to the premium received by the
Portfolio 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 Portfolio
enters into a closing transaction), the Portfolio 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.

o Financial futures contracts--Certain Portfolios may purchase or sell financial
futures contracts and options on such financial futures contracts. Financial
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
Portfolio deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to the contract,
the Portfolio agrees to receive from or pay to the broker an amount of cash
equal to the daily fluctuation in the value of the contract. Such receipts or
payments are known as variation margin and are recorded by the Portfolio as
unrealized gains or losses. When the contract is closed, the Portfolio 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.

o Swaps--Certain Portfolios may enter into swap agreements, which are OTC
contracts in which the Portfolio and a counterparty agree to make periodic net
payments on a specified notional amount. The net payments can be made for a set
period of time or may be triggered by a predetermined credit event. The net
periodic payments may be based on a fixed or variable interest rate; the change
in market value of a specified security, basket of securities, or index; or the
return generated by a security. These periodic payments received or made by the
Portfolio are recorded in the accompanying Statement of Operations as realized
gains or losses, respectively. Gains or losses are also realized upon
termination of the swap agreements. Swaps are marked-to-market daily and changes
in value are recorded as unrealized appreciation (depreciation). Risks include
changes in the returns of the underlying instruments, failure of the
counterparties to perform under the contracts' terms and the possible lack of
liquidity with respect to the swap agreements.

(h) 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 U.S. dollars. Realized and unrealized gains or losses
from investments include the effects of foreign exchange rates on investments.
The Portfolios may invest in foreign securities, which may involve a number of
risk factors and special considerations not present with investments in
securities of U.S. corporations.

(i) Short sales--When a Portfolio engages in a short sale, an amount equal to
the proceeds received by the Portfolio is reflected as an asset and an
equivalent liability. The amount of the liability is subsequently
marked-to-market to reflect the market value of the short sale. The Portfolio
maintains a segregated account of securities as collateral for the short sales.
The Portfolio is exposed to market risk based on the amount, if any, that the
market value of the security exceeds the market value of the securities in the
segregated account. The Portfolio is required to repay the counterparty any
dividends or interest received on the security sold short.

(j) Dividends and distributions--BlackRock Money Market Portfolio declares
dividends daily and reinvests daily such dividends (net of non-resident alien
tax and backup withholding tax withheld) in additional fund shares at net asset
value. Dividends are declared from the total of net investment income.
Distribution of realized gain, if any, on investments are paid at least
annually. For BlackRock Balanced Capital Portfolio, BlackRock Fundamental Growth
Portfolio, BlackRock Global Allocation Portfolio and BlackRock Large Cap Core
Portfolio, dividends and distributions paid by the Portfolios are recorded on
the ex-dividend dates. For BlackRock Bond Portfolio, BlackRock Government Income
Portfolio and BlackRock High Income Portfolio, dividends from net investment
income are declared daily and paid monthly. Distributions of capital gains are
recorded on the ex-dividend dates. Portions of the dividends paid by BlackRock
Bond Portfolio during the year ended December 31, 2006 were characterized as a
tax return of capital.

(k) Securities lending--Certain Portfolios may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities. The
market value of the loaned securities is determined at the close of business of
the Portfolio and any additional required collateral is delivered to the
Portfolio on the next business day. Where the Portfolio receives securities as
collateral for the loaned securities, it collects a fee from the borrower. The
Portfolio typically receives the income on the loaned securities but does not
receive the income on the collateral. Where the Portfolio receives cash
collateral, it may invest such collateral and retain the amount earned on such
investment, net of any amount rebated to the borrower. Loans of securities are
terminable at any time and the borrower, after notice, is required to return
borrowed securities within five business days. The Portfolio may pay reasonable
finder's, lending agent, administrative and custodial fees in connection with
its loans. In the event that the borrower defaults on its obligation to return
borrowed securities because of insolvency or for any other reason, the Portfolio
could experience delays and costs in gaining access to the collateral. The
Portfolio also could suffer a loss where the value of the collateral falls below
the market value of the borrowed securities, in the event of borrower default or
in the event of losses on investments made with cash collateral.

(l) Expenses--Certain expenses have been allocated to the individual Portfolios
in the Fund on a pro rata basis based on the respective aggregate net asset
value of each Portfolio included in the Fund.

(m) Mortgage dollar rolls--Certain Portfolios may sell mortgage-backed
securities for delivery in the current month and simultaneously contract to
repurchase substantially similar (same type, coupon and maturity) securities on
a specific future date.

(n) Bank overdraft--The BlackRock Fundamental Growth Portfolio, BlackRock
Government Income Portfolio, BlackRock Large Cap Core Portfolio and BlackRock
Money Market Portfolio recorded a bank overdraft which resulted from management
estimates of available cash. The BlackRock Bond Portfolio recorded a bank
overdraft resulting from a timing difference of security transaction
settlements.

BlackRock Series Fund, Inc.
Notes to Financial Statements (Continued)
================================================================================

(o) Recent accounting pronouncements--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes--an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity including mutual funds before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on each of the Portfolio's financial statements, if any, is currently being
assessed.

In addition, in September 2006, Statement of Financial Accounting Standards No.
157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for
fiscal years beginning after November 15, 2007. FAS 157 defines fair value,
establishes a framework for measuring fair value and expands disclosures about
fair value measurements. Management is currently evaluating the implications of
FAS 157. At this time, its impact on each of the Portfolio's financial
statements has not been determined.

(p) Reclassifications--U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, the current year's
permanent book/tax differences have been reclassified as follows:

BlackRock Balanced Capital Portfolio

$190,853 has been reclassified between undistributed net investment income and
accumulated net realized capital losses as a result of permanent differences
attributable to swap agreements, amortization methods on fixed income
securities, accounting for paydowns and foreign currency transactions. This
reclassification has no effect on net assets or net asset value per share.

BlackRock Bond Portfolio

$439,875 has been reclassified between accumulated distributions in excess of
net investment income and accumulated net realized capital losses as a result of
permanent differences attributable to foreign currency transactions, accounting
for swap agreements and paydowns and amortization methods of fixed income
securities. This reclassification has no effect on net assets or net asset value
per share.

BlackRock Fundamental Growth Portfolio

$21,332 has been reclassified between paid-in capital in excess of par and
accumulated distributions in excess of net investment income and $17,188 has
been reclassified between accumulated distributions in excess of net investment
income and accumulated net realized capital losses as a result of permanent
differences attributable to distributions paid in excess of taxable income and
foreign currency transactions. These reclassifications have no effect on net
assets or net asset value per share.

BlackRock Global Allocation Portfolio

$2,208,760 has been reclassified between undistributed net realized capital
gains and distributions in excess of net investment income as a result of
permanent differences attributable to foreign currency transactions, gains from
the sale of stock of passive foreign investment companies, amortization methods
on fixed income securities and the characterization of expenses. This
reclassification has no effect on net assets or net asset value per share.

BlackRock Government Income Portfolio

$34,051 has been reclassified between accumulated net realized capital losses
and accumulated distributions in excess of net investment income as a result of
permanent differences attributable to accounting for paydowns and swap
agreements. This reclassification has no effect on net assets or net asset value
per share.

================================================================================

BlackRock High Income Portfolio

$1,317,507 has been reclassified between paid-in capital in excess of par and
accumulated net realized capital losses and $8,152 has been reclassified between
accumulated distributions in excess of net investment income and accumulated net
realized capital losses as a result of permanent differences attributable to
expiration of capital loss carryforwards and amortization methods on fixed
income securities. These reclassifications have no effect on net assets or net
asset value per share.

2. Investment Advisory Agreement and Transactions with Affiliates:

On September 29, 2006, BlackRock, Inc. and Merrill Lynch combined Merrill
Lynch's investment management business, Merrill Lynch Investment Managers, L.P.
("MLIM") and its affiliates, with BlackRock, Inc. to create a new independent
company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest
in the combined company and The PNC Financial Services Group, Inc. ("PNC"), has
approximately a 34% economic and voting interest. The new company operates under
the BlackRock name and is governed by a board of directors with a majority of
independent members.

On August 15, 2006, shareholders of the Fund, on behalf of the Portfolios,
approved a new Investment Advisory Agreement with the Manager. BlackRock
Advisors, Inc. was recently reorganized into a limited liability company and
renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between
the Fund and the Manager became effective on September 29, 2006. Prior to
September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is
Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of
Merrill Lynch, which is the limited partner. The Fund has also entered into

Portfolios' average daily net assets not exceeding $250 million, .45% of the
next $50 million, .40% of the next $100 million, .35% of the next $400 million,
and .30% of average daily net assets in excess of $800 million.

For BlackRock Bond Portfolio, BlackRock Government Income Portfolio and
BlackRock High Income Portfolio, the Manager has entered into a sub-advisory
agreement with BlackRock Financial Management, Inc. ("BFM"), an affiliate of the
Manager, under which the Manager pays the Sub-Adviser for services it provides a
monthly fee that is a percentage of the management fee paid by the Fund to the
Manager.

For BlackRock Fundamental Growth Portfolio and BlackRock Large Cap Core
Portfolio, the Manager has entered into a sub-advisory agreement with BlackRock
Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the

MLIM reimbursed the BlackRock Global Allocation Portfolio $45,137 related to a
regulatory issue on an investment.

The Fund has received an exemptive order from the Securities and Exchange
Commission permitting it to lend each Portfolio's securities to Merrill Lynch,
Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch,
or its affiliates. Pursuant to that order, the Fund also has retained BIM as the
securities lending agent for a fee based on a share of the returns on investment
of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill
Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM,
LLC was the securities lending agent. BIM may, on behalf of the Fund and
Portfolios, invest cash collateral received by the Portfolios for such loans,
among other things, in a private investment company managed by the Manager or in
registered money market funds advised by the Manager or its affiliates.

As of December 31, 2006, the following Portfolios lent securities to MLPF&S:

5. Short-Term Borrowings:

The Fund (excluding the BlackRock Money Market Portfolio), along with certain
other funds managed by the Manager and its affiliates (or MLIM and its
affiliates), is a party to a $500,000,000 credit agreement with a group of
lenders. The Fund may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Fund may
borrow up to the maximum amount allowable under the Fund's current prospectus
and statement of additional information, subject to various other legal,
regulatory or contractual limits. On November 22, 2006, the credit agreement was
renewed for one year under substantially the same terms. The Fund pays a
commitment fee of .06% per annum based on the Fund's pro rata share of the
unused portion of the credit agreement. Amounts borrowed under the credit
agreement bear interest at a rate equal to, at each Fund's election, the federal
funds rate plus .35% or a base rate as defined in the credit agreement. The Fund
did not borrow under the credit agreement during the year ended December 31,
2006.

6. Commitments:

At December 31, 2006, the Fund had entered into foreign exchange contracts, in
addition to the contracts listed on the schedule of investments, under which it
had agreed to purchase and sell various foreign currencies with an approximate
value of $139,000 and $64,000, respectively, for BlackRock Global Allocation
Portfolio.

7. Distributions to Shareholders:

The tax character of distributions paid during the fiscal years ended December

- --------------------------------------------------------------------------------
 *    On December 31, 2006, the Portfolio had a net capital loss carryforward of
      $63,879,239, of which $40,546,648 expires in 2010 and $23,332,591 expires
      in 2011. This amount will be available to offset like amounts of any
      future taxable gains.
**    The difference between book-basis and tax-basis net unrealized gains is
      attributable primarily to the tax deferral of losses on wash sales, the
      realization for tax purposes of unrealized gains/losses on certain futures
      contracts, the difference between book and tax amortization methods for
      premiums and discounts on fixed income securities and other book/tax
      temporary differences.

BlackRock Series Fund, Inc.
Report of Independent Registered Public Accounting Firm
================================================================================

To the Shareholders and Board of Directors of
BlackRock Series Fund, Inc.:

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of the BlackRock Balanced Capital Portfolio,
BlackRock Bond Portfolio, BlackRock Fundamental Growth Portfolio, BlackRock
Global Allocation Portfolio, BlackRock Government Income Portfolio, BlackRock
High Income Portfolio, BlackRock Large Cap Core Portfolio and BlackRock Money
Market Portfolio (formerly Mercury Balanced Capital Strategy Portfolio, Mercury
Core Bond Strategy Portfolio, Mercury Fundamental Growth Strategy Portfolio,
Mercury Global Allocation Strategy Portfolio, Mercury Intermediate Government
Bond Portfolio, Mercury High Yield Portfolio, Mercury Large Cap Core Strategy
Portfolio and Mercury Money Reserve Portfolio, respectively), eight of the
portfolios constituting the BlackRock Series Fund, Inc. (the "Fund") (formerly
FAM Series Fund, Inc.), as of December 31, 2006, and the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each of the five years in the period then ended. These financial statements and
financial highlights are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of December 31, 2006, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective eight portfolios constituting the BlackRock Series Fund, Inc.
as of December 31, 2006, the results of their operations for the year then
ended, the changes in their net assets for each of the two years in the period
then ended, and their financial highlights for each of the five years in the
period then ended, in conformity with accounting principles generally accepted
in the United States of America.

BlackRock Investment Advisory Agreement -- Matters Considered by the Board

The following disclosure appeared in the June 30, 2006 Semi-Annual Report of the
Portfolios and is the discussion referred to in "New BlackRock Sub-Advisory
Agreements -- Matters Considered by the Board" and "Approvals to Correct Fee
Schedules" below. The term "Investment Adviser as used herein refers to Merrill
Lynch Investment Managers, L.P.

In connection with the Transaction between Merrill Lynch and BlackRock, the
Fund's Board of Directors considered a new investment advisory agreement (the
"New Investment Advisory Agreement") between the Fund, on behalf of the
Portfolios, and BlackRock Advisors, Inc. ("BlackRock Advisors"). If the New
Investment Advisory Agreement is approved by shareholders, it will become
effective upon the closing of the Transaction, which is expected in the third
quarter of 2006.

The Board discussed the New Investment Advisory Agreement at telephonic and
in-person meetings held during April and May 2006. The Board, including the
independent directors, approved the New Investment Advisory Agreement on May 8,
2006.

To assist the Board in its consideration of the New Investment Advisory
Agreement, BlackRock provided materials and information about BlackRock,
including its financial condition and asset management capabilities and
organization, and Merrill Lynch provided materials and information about the
Transaction. The independent directors, through their independent legal counsel,
also requested and received additional information from Merrill Lynch and
BlackRock in connection with their consideration of the New Investment Advisory
Agreement. The additional information was provided in advance of the May 2006
meeting. In addition, the independent directors consulted with their counsel and
Fund counsel on numerous occasions, discussing, among other things, the legal
standards and certain other considerations relevant to the directors'
deliberations.

At the Board meetings, the directors discussed with Merrill Lynch management and
certain BlackRock representatives the Transaction, its strategic rationale and
BlackRock's general plans and intentions regarding the Portfolios. At these
Board meetings, representatives of Merrill Lynch and BlackRock made
presentations to and responded to questions from the Board. The directors also
inquired about the plans for and anticipated roles and responsibilities of
certain employees and officers of the Investment Adviser and certain affiliates
being transferred to BlackRock in connection with the Transaction. The
independent directors of the Board also conferred separately and with their
counsel about the Transaction and other matters related to the Transaction on a
number of occasions, including in connection with the April and May 2006
meetings. After the presentations and after reviewing the written materials
provided, the independent directors met in executive sessions with their counsel
to consider the New Investment Advisory Agreement.

In connection with the Board's review of the New Investment Advisory Agreement,
Merrill Lynch and/or BlackRock advised the directors about a variety of matters.
The advice included the following, among other matters:

      o     that there is not expected to be any diminution in the nature,
            quality and extent of services provided to any Portfolio and its
            shareholders by BlackRock Advisors, including compliance services;

      o     that operation of New BlackRock as an independent investment
            management firm will enhance its ability to attract and retain
            talented professionals;

      o     that each Portfolio should benefit from having access to BlackRock's
            state of the art technology and risk management analytic tools,
            including investment tools, provided under the BlackRock
            Solutions(R) brand name;

      o     that BlackRock has no present intention to alter any applicable
            expense waivers or reimbursements currently in effect and, while it
            reserves the right to do so in the future, it would seek the
            approval of the Board before making any changes;

      o     that in connection with the Transaction, Merrill Lynch and BlackRock
            have agreed to conduct, and use reasonable best efforts to cause
            their respective affiliates to conduct, their respective businesses
            in compliance with the conditions of Section 15(f) of the Investment
            Company Act of 1940 (the "1940 Act") in relation to any public funds
            advised by BlackRock or the Investment Adviser (or its affiliates),
            respectively; and

      o     that Merrill Lynch and BlackRock would derive benefits from the
            Transaction and that, as a result, they have a different financial
            interest in the matters that were being considered than do Portfolio
            shareholders.

The directors considered the information provided by Merrill Lynch and BlackRock
above, and, among other factors, the following:

      o     the potential benefits to Portfolio shareholders from being part of
            a combined fund family with BlackRock-sponsored funds, including
            possible economies of scale and access to investment opportunities;

      o     the potential for expanding distribution of Portfolio shares through
            improved access to third party distribution;

      o     the reputation, financial strength and resources of BlackRock and
            its investment advisory subsidiaries and the anticipated financial
            strength and resources of New BlackRock;

      o     the compliance policies and procedures of BlackRock Advisors;

      o     the terms and conditions of the New Investment Advisory Agreement,
            including the fact that the schedule of each Portfolio's total
            advisory fees will not increase by virtue of the New Investment
            Advisory Agreement, but will remain the same;

      o     that in May 2005, the Board had performed a full annual review of
            the investment advisory agreement currently in effect for each
            Portfolio (the "Current Investment Advisory Agreement") as required
            by the 1940 Act and has determined that the Investment Adviser has
            the capabilities, resources and personnel necessary to provide the
            advisory and administrative services currently provided to each
            Portfolio; and that the advisory and/or management fees paid by each
            Portfolio, taking into account any applicable agreed-upon fee
            waivers and breakpoints, represent reasonable compensation to the
            Investment Adviser in light of the services provided, the costs to
            the Investment Adviser of providing those services, economies of
            scale, the fees and other expenses paid by similar funds (including
            information provided by Lipper Inc. ["Lipper"]), and such other
            matters as the directors have considered relevant in the exercise of
            their reasonable judgment; and

      o     that Merrill Lynch agreed to pay all expenses of each Portfolio in
            connection with the Board's consideration of the New Investment
            Advisory Agreement and related agreements and all costs of
            shareholder approval of the New Investment Advisory Agreement and as
            a result no Portfolio would bear any costs in obtaining shareholder
            approval of the New Investment Advisory Agreement.

Disclosure of Investment Advisory Agreement (Continued)
================================================================================

Certain of these considerations are discussed in more detail below.

In its review of the New Investment Advisory Agreement, the Board assessed the
nature, scope and quality of the services to be provided to each Portfolio by
the personnel of BlackRock Advisors and its affiliates, including administrative
services, shareholder services, oversight of fund accounting, marketing services
and assistance in meeting legal and regulatory requirements. In its review of
the New Investment Advisory Agreement, the Board also considered a range of
information in connection with its oversight of the services to be provided by
BlackRock Advisors and its affiliates. Among the matters considered for each
Portfolio were: (a) fees (in addition to management fees) to be paid to
BlackRock Advisors and its affiliates by the Portfolio; (b) operating expenses
paid to third parties; (c) the resources devoted to and compliance reports
relating to the Portfolio's investment objective, policies and restrictions, and
its compliance with its Code of Ethics and BlackRock Advisors' compliance
policies and procedures; and (d) the nature, cost and character of
non-investment management services to be provided by BlackRock Advisors and its
affiliates.

In the period prior to the Board meetings to consider renewal of the Current
Investment Advisory Agreement, the Board had requested and received materials
specifically relating to the Current Investment Advisory Agreement. For each
Portfolio, these materials included (a) information compiled by Lipper on the
fees and expenses and the investment performance of the Portfolio as compared to
a comparable group of funds as classified by Lipper; (b) a discussion by the
portfolio management team for the Portfolio on investment strategies used by the
Portfolio during its most recent fiscal year; (c) information on the
profitability to the Investment Adviser of the Current Investment Advisory
Agreement and other payments received by the Investment Adviser and its
affiliates from the Portfolio; and (d) information provided by the Investment
Adviser concerning services related to the valuation and pricing of portfolio
holdings, allocation of any brokerage fees, portfolio turnover statistics, and
direct and indirect benefits to the Investment Adviser and its affiliates from
their relationship with the Portfolio.

In their deliberations, the directors considered information received in
connection with their most recent continuation of the Current Investment
Advisory Agreement, in addition to information provided by BlackRock and
BlackRock Advisors in connection with their evaluation of the terms and
conditions of the New Investment Advisory Agreement. The directors did not
identify any particular information that was all-important or controlling, and
each director attributed different weights to the various factors. The
directors' determinations were made separately in respect of each Portfolio. The
directors, including a majority of the independent directors, concluded that the
terms of the New Investment Advisory Agreement are appropriate, that the fees to
be paid are reasonable in light of the services to be provided to the Portfolio,
and that the New Investment Advisory Agreement should be approved and
recommended to each Portfolio's shareholders.

Nature, Quality and Extent of Services Provided. The Board reviewed the nature,
extent and quality of services provided by the Investment Adviser, including the
investment advisory services and the resulting performance of each Portfolio, as
well as the nature, quality and extent of services expected to be provided by
BlackRock Advisors. The Board focused primarily on the Investment Adviser's
investment advisory services and each Portfolio's investment performance, but
also considered certain areas in which both the Investment Adviser and the
Portfolio receive services as part of the Merrill Lynch complex. The Board
compared each Portfolio's performance -- both including and excluding the
effects of fees and expenses -- to the performance of a comparable group of
mutual funds, and the performance of a relevant index or combination of indexes.
While the Board reviews performance data at least quarterly, consistent with the
Investment Adviser's investment goals, the Board attaches more importance to
performance over relatively long periods of time, typically three to five years.

In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors under the New Investment Advisory Agreement, the directors
considered, among other things, the expected impact of the Transaction on the
operations, facilities, organization and personnel of BlackRock Advisors

================================================================================

and how it would affect each Portfolio; the ability of BlackRock Advisors to
perform its duties after the Transaction; and any anticipated changes to the
current investment and other practices of each Portfolio. The directors
considered BlackRock's advice as to proposed changes in portfolio management
personnel of certain Portfolios after the closing of the Transaction.

The directors were given information with respect to the potential benefits to
each Portfolio and its shareholders from having access to BlackRock's state of
the art technology and risk management analytic tools, including the investment
tools provided under the BlackRock Solutions brand name.

The directors were advised that, as a result of Merrill Lynch's equity interest
in BlackRock after the Transaction, each Portfolio will continue to be subject
to restrictions concerning certain transactions involving Merrill Lynch
affiliates (for example, transactions with a Merrill Lynch broker-dealer acting
as principal) absent revised or new regulatory relief. The directors were
advised that a revision of existing regulatory relief with respect to these
restrictions was being sought from the Securities and Exchange Commission and
were advised of the possibility of receipt of such revised regulatory relief.
There can be no assurance that such relief will be obtained.

Based on their review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, the directors
determined that the nature and quality of services to be provided to each
Portfolio under the New Investment Advisory Agreement were expected to be as
good or better than that provided under the Current Investment Advisory
Agreement. It was noted, however, that it is expected that there will be changes
in personnel following the Transaction and the combination of the operations of
the Investment Adviser and its affiliates with those of BlackRock. The directors
noted that if current portfolio managers or other personnel cease to be
available, the Board would consider all available options, which could include
seeking the investment advisory or other services of BlackRock affiliates.
Accordingly, the directors concluded that, overall, they were satisfied at the
present time with assurances from BlackRock and BlackRock Advisors as to the
expected nature, extent and quality of the services to be provided to each
Portfolio under the New Investment Advisory Agreement.

Costs of Services Provided and Profitability. It was noted that, in conjunction
with the recent review of the Current Investment Advisory Agreement, the
directors had received, among other things, a report from Lipper comparing each
Portfolio's fees, expenses and performance to those of a peer group selected by
Lipper, and information as to the fees charged by the Investment Adviser or its
affiliates to other registered investment company clients for investment
management services. The Board reviewed each Portfolio's contractual management
fee rate and actual management fee rate as a percentage of total assets at
common asset levels -- the actual rate includes advisory fees and the effects of
any fee waivers -- compared to the other funds in its Lipper category. They also
compared each Portfolio's total expenses to those of other comparable funds. The
information showed that each Portfolio had fees and expenses within the range of
fees and expenses of comparable funds. For each of the Mercury Fundamental
Growth Strategy, Mercury Global Allocation Strategy and Mercury Large Cap Core
Strategy Portfolios, the Board considered the services to be provided by and the
fees to be charged by BlackRock Advisors to other funds with similar investment
mandates and noted that the fees charged by BlackRock Advisors in those cases,
including fee waivers and expense reimbursements, were generally comparable to
those being charged to the Portfolio. The Board concluded that the each
Portfolio's management fee and fee rate and overall expense ratio are reasonable
compared to those of other comparable funds.

In evaluating the costs of the services to be provided by BlackRock Advisors
under the New Investment Advisory Agreement, the directors considered, among
other things, whether advisory fees or other expenses would change as a result
of the Transaction. Based on their review of the materials provided and the fact
that the New Investment Advisory Agreement is substantially similar to the
Current Investment Advisory Agreement in all material respects, including the
rate of compensation, the directors determined that the Transaction should not
increase the total fees payable, including any fee waivers and expense
reimbursements, for advisory and administrative services. The directors noted
that it was not possible to predict with certainty New BlackRock's future
profitability from its relationship with each Portfolio.

================================================================================

The directors discussed with BlackRock Advisors its general methodology to be
used in determining New BlackRock's profitability with respect to its
relationship with each Portfolio. The directors noted that they expect to
receive profitability information from New BlackRock on at least an annual basis
and thus be in a position to evaluate whether any adjustments in a Portfolio's
fees and/or fee breakpoints would be appropriate.

Fees and Economies of Scale. The Board considered the extent to which economies
of scale might be realized as the assets of each Portfolio increase and whether
there should be changes in the management fee rate or structure in order to
enable the Portfolio to participate in these economies of scale. The Board
determined that changes were not currently necessary and that each Portfolio
appropriately participated in these economies of scale.

In reviewing the Transaction, the directors considered, among other things,
whether advisory fees or other expenses would change as a result of the
Transaction. Based on the fact that the New Investment Advisory Agreement is
substantially similar to the Current Investment Advisory Agreement in all
material respects, including the rate of compensation, the directors determined
that as a result of the Transaction, no Portfolio's total advisory fees would be
higher than the fees under its Current Investment Advisory Agreement. The
directors noted that in conjunction with their most recent deliberations
concerning the Current Investment Advisory Agreement, the directors had
determined that the total fees for advisory and administrative services for each
Portfolio were reasonable in light of the services provided. It was noted that
in conjunction with the recent review of the Current Investment Advisory
Agreement, the directors had received, among other things, a report from Lipper
comparing each Portfolio's fees, expenses and performance to those of a peer
group selected by Lipper, and information as to the fees charged by the
Investment Adviser to other registered investment company clients for investment
management services. The directors concluded that, because the rates for
advisory fees for each Portfolio would be no higher than its current fee rates,
the proposed management fee structure, including any fee waivers, was reasonable
and that no additional changes were currently necessary.

Fall-Out Benefits. In evaluating the fall-out benefits to be received by
BlackRock Advisors under the New Investment Advisory Agreement, the directors
considered whether the Transaction would have an impact on the fall-out benefits
received by the Investment Adviser by virtue of the Current Investment Advisory
Agreement. Based on their review of the materials provided, including materials
received in connection with their most recent continuance of the Current
Investment Advisory Agreement, and their discussions with management of the
Investment Adviser and BlackRock, the directors determined that those benefits
could include increased ability for BlackRock to distribute shares of its funds
and other investment products and, where applicable, to obtain research services
using portfolio transaction brokerage commissions. The directors also considered
possible benefits stemming from the proposal that PFPC Financial Services, an
affiliate of BlackRock, serve as transfer agent for each Portfolio following the
Transaction. The directors noted that any benefits were difficult to quantify
with certainty at this time, and indicated that they would continue to evaluate
them going forward.

Investment Performance. The directors considered investment performance for each
Portfolio. The directors compared each Portfolio's performance -- both including
and excluding the effects of fees and expenses -- to the performance of a
comparable group of mutual funds, and the performance of a relevant index or
combination of indexes. The comparative information received from Lipper showed
each Portfolio's performance at various levels within the range of performance
of comparable funds over different time periods. While the Board reviews
performance data at least quarterly, consistent with the Investment Adviser's
investment goals, the Board attaches more importance over relatively long
periods of time, typically three to five years. The directors believed each
Portfolio's performance was satisfactory. Also, the directors took into account
the investment performance of funds currently advised by BlackRock Advisors. The
Board considered comparative information from Lipper which showed that the
performance of the funds advised by BlackRock Advisors was within the range of
performance of comparable funds over different time periods. The Board noted
BlackRock's considerable investment management experience and capabilities, but
was unable to predict what effect, if any, consummation of the Transaction would
have on the future performance of any Portfolio.

================================================================================

Conclusion. After the independent directors of the Fund deliberated in executive
session, the entire Board, including the independent directors, approved the New
Investment Advisory Agreement on behalf of each Portfolio, concluding that the
Portfolio's advisory fee rate was reasonable in relation to the services
provided and that the New Investment Advisory Agreement was in the best
interests of the shareholders. In approving the New Investment Advisory
Agreement, the Board noted that it anticipated reviewing the continuance of the
agreement in advance of the expiration of the initial two-year period.

New BlackRock Sub-Advisory Agreements -- Matters Considered by the Board

At an in-person meeting held on August 16-17, 2006, the Board of Directors,
including the independent directors, discussed and approved the sub-advisory
agreements between BlackRock Advisors, LLC (previously organized as BlackRock
Advisors, Inc.) ("BlackRock Advisors") and the following affiliates (the
"Sub-Advisers") (the "BlackRock Sub-Advisory Agreements"):

      o     BlackRock Investment Management, LLC ("BIM"), with respect to each
            of Fundamental Growth Portfolio, Large Cap Portfolio and a portion
            of Balanced Capital Portfolio and Global Allocation Portfolio.
            Pursuant to the pertinent BlackRock Sub-Advisory Agreement, BIM
            receives a monthly fee from BlackRock Advisors at an annual rate
            equal to 74% of the advisory fee received by BlackRock Advisors from
            each of Fundamental Growth Portfolio, Global Small Cap Portfolio and
            Large Cap Portfolio and 37% of the advisory fee received by
            BlackRock Advisors from each of Balanced Capital Portfolio and
            Global Allocation Portfolio.

      o     BlackRock Financial Management, Inc. ("BFM"), with respect to each
            of Government Income Portfolio and High Income Portfolio and a
            portion of Balanced Capital Portfolio. Pursuant to the pertinent
            BlackRock Sub-Advisory Agreement, BFM receives a monthly fee from
            BlackRock Advisors at an annual rate equal to 59% of the advisory
            fee received by BlackRock Advisors from each of Intermediate
            Government Portfolio and High Income Portfolio and 37% of the
            advisory fee received by BlackRock Advisors from Balanced Capital
            Portfolio.

      o     BlackRock Asset Management U.K. Limited ("BAM UK"), with respect to
            Global Allocation Portfolio. Pursuant to the pertinent BlackRock
            Sub-Advisory Agreement, BAM UK receives a monthly fee from BlackRock
            Advisors at an annual rate equal to 37% of the advisory fee received
            by BlackRock Advisors from Global Allocation Portfolio.

      o     BlackRock Institutional Management Corporation ("BIMC"), with
            respect to Money Market Portfolio. Pursuant to the pertinent
            BlackRock Sub-Advisory Agreement, BIMC receives a monthly fee from
            BlackRock Advisors at an annual rate equal to 59% of the advisory
            fee received by BlackRock Advisors from Money Market Portfolio.

The BlackRock Sub-Advisory Agreements became effective on September 29, 2006, at
the same time the New Investment Advisory Agreement with BlackRock Advisors
became effective.

BlackRock Advisors pays the Sub-Advisers out of its own resources, and there is
no increase in the expenses of any Portfolio as a result of the BlackRock
Sub-Advisory Agreements.

In approving the BlackRock Sub-Advisory Agreements at the August 2006 in-person
meeting, the Board reviewed its considerations in connection with its approval
of the New Investment Advisory Agreement in May 2006. The Board relied on the
same information and considered the same factors as those discussed above in
connection with the approval of the New Investment Advisory Agreement. In
reviewing the sub-advisory fee rates provided for in the BlackRock Sub-Advisory
Agreements, the Board noted the fact that both BlackRock Advisors and each
Sub-Adviser have significant responsibilities under their respective advisory
agreements. Under the New Investment Advisory Agreement, BlackRock Advisors
remains responsible for the overall management of each Portfolio and for
oversight of each Portfolio's operations and administration. Under the BlackRock
Sub-Advisory Agreements, each Sub-Adviser provides advisory services to each
pertinent Portfolio and is responsible for the day-to-day management of the
Portfolio's

portfolio. The Board also took into account the fact that there is no increase
in total advisory fees paid by any Portfolio as a result of the BlackRock
Sub-Advisory Agreements. Based on its considerations, the Board concluded that
it was a reasonable allocation of fees for the pertinent Sub-Adviser to receive
the portion of the advisory fee paid by each Portfolio to BlackRock Advisors, as
noted above.

After the independent directors deliberated in executive session, the entire
Board, including the independent directors, approved each BlackRock Sub-Advisory
Agreement, concluding that the sub-advisory fee was reasonable in relation to
the services provided and that each BlackRock Sub-Advisory Agreement was in the
best interests of each pertinent Portfolio's shareholders.

Approvals to Correct Fee Schedules

As discussed above, at a meeting on May 8, 2006, the Board, including the
independent directors, approved the New Investment Advisory Agreement between
the Fund, on behalf of the Portfolios, and BlackRock Advisors. The New
Investment Advisory Agreement as approved by the Board contained an advisory fee
schedule for each Portfolio that was the same as the fee schedule set forth in
the investment advisory agreement in effect for the Portfolio at that time (the
"Current Investment Advisory Agreement"). At a shareholder meeting on August 15,
2006, the shareholders of each Portfolio approved a new investment advisory
agreement between BlackRock Advisors and the Fund, on behalf of the Portfolios,
but in a form that contained incorrect advisory fee schedules for the
Portfolios. The proxy statement sent to Portfolio shareholders in connection
with the shareholder meeting (the "Proxy Statement") stated in several places
that the advisory fees payable by each Portfolio under the New Investment
Advisory Agreement would be the same as the fees payable under the Current
Investment Advisory Agreement. However, subsequent to the shareholder meeting,
it was discovered that the advisory fee schedules for the Portfolios were
incorrectly presented in an appendix in the Proxy Statement. The advisory fee
schedules for Global Allocation Portfolio and Fundamental Growth Portfolio were
stated at higher levels than the fee schedules then in effect and did not
indicate the breakpoint schedules that would provide for a lower advisory fee at
higher asset levels. The advisory fee schedules for Balanced Capital Portfolio,
Large Cap Core Portfolio, Core Bond Portfolio, High Yield Portfolio,
Intermediate Government Portfolio and Money Reserve Portfolio presented the
correct advisory fee breakpoints but did not state the correct means of applying
the breakpoints.

At a September 22, 2006 meeting, the Board considered ratification and approval
of investment advisory agreements between BlackRock Advisors and the Fund, on
behalf of the Portfolios, in the form approved by shareholders with the higher,
incorrect advisory fee schedules. The Board also considered approval of
amendments to such investment advisory agreements decreasing the advisory fees
to the lower, correct advisory fee schedules (including the calculation of the
fee based on a uniform percentage, as discussed at the September 22, 2006
meeting) previously approved by the Board at the May 2006 meeting. After
discussion, the Directors, and separately the non-interested directors present,
in person, at the meeting, (a) ratified and approved an investment advisory
agreement between BlackRock Advisors and the Fund, on behalf of each Portfolio,
with the higher fee schedule that was approved by shareholders and (b) approved
an amendment to each such investment advisory agreement to reduce the advisory
fee schedule to the lower, correct advisory fee schedule previously approved by
the Board at the May 2006 meeting.

The Board also discussed the BlackRock Sub-Advisory Agreements between BlackRock
Advisors and BIM (with respect to Fundamental Growth Portfolio, Large Cap
Portfolio, Balanced Capital Portfolio and Global Allocation Portfolio), BFM
(with respect to Government Income Portfolio, High Income Portfolio and Balanced
Capital Portfolio), BAM UK (with respect to Global Allocation Portfolio) and
BIMC (with respect to Money Market Portfolio). The Board reviewed and reaffirmed
their considerations in connection with their approval of the BlackRock
Sub-Advisory Agreements at the August 16-17, 2006 meeting. The Directors, and
separately the non-interested directors present, in person, at the meeting, then
ratified and approved each BlackRock Sub-Advisory Agreement as previously
approved at the August 16-17, 2006 meeting.

        (e)(1) The registrant's audit committee (the "Committee") has adopted
        policies and procedures with regard to the pre-approval of services.
        Audit, audit-related and tax compliance services provided to the
        registrant on an annual basis require specific pre-approval by the



        Committee. The Committee also must approve other non-audit services
        provided to the registrant and those non-audit services provided to the
        registrant's affiliated service providers that relate directly to the
        operations and the financial reporting of the registrant. Certain of
        these non-audit services that the Committee believes are a) consistent
        with the SEC's auditor independence rules and b) routine and recurring
        services that will not impair the independence of the independent
        accountants may be approved by the Committee without consideration on a
        specific case-by-case basis ("general pre-approval"). However, such
        services will only be deemed pre-approved provided that any individual
        project does not exceed $5,000 attributable to the registrant or $50,000
        for all of the registrants the Committee oversees. Any proposed services
        exceeding the pre-approved cost levels will require specific
        pre-approval by the Committee, as will any other services not subject to
        general pre-approval (e.g., unanticipated but permissible services). The
        Committee is informed of each service approved subject to general
        pre-approval at the next regularly scheduled in-person board meeting.

        (h) The registrant's audit committee has considered and determined that
        the provision of non-audit services that were rendered to the
        registrant's investment adviser and any entity controlling, controlled
        by, or under common control with the investment adviser that provides
        ongoing services to the registrant that were not pre-approved pursuant
        to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible
        with maintaining the principal accountant's independence.
