Annual Report -- December 31, 2006 A Letter to Shareholders ================================================================================ Dear Shareholder As 2007 begins, we are able to look back on 2006 as a volatile, but ultimately, a positive year for most major markets. Returns for the annual and semi-annual periods ended December 31, 2006 were as follows: Total Returns as of December 31, 2006 - ------------------------------------------------------------------------------------------------------------------ 6-month 12-month - ------------------------------------------------------------------------------------------------------------------ U.S. equities (Standard & Poor's 500 Index)............................................ +12.74% +15.79% Small cap U.S. equities (Russell 2000 Index)........................................... + 9.38 +18.37 International equities (MSCI Europe, Australasia, Far East Index)...................... +14.69 +26.34 Fixed income (Lehman Brothers Aggregate Bond Index).................................... + 5.09 + 4.33 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index)......................... + 4.55 + 4.84 High yield bonds (Credit Suisse High Yield Index)...................................... + 8.14 +11.92 - ------------------------------------------------------------------------------------------------------------------ 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 "What's Ahead in 2007: An Investment Perspective," or view it online at 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. ----------------------- Robert C. Doll, Jr. President and Director 1 - -------------------------------------------------------------------------------- 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. Kurt Schansinger Vice President and Senior Portfolio Manager Keith Anderson Fixed Income Portfolio Manager 3 - -------------------------------------------------------------------------------- Effective October 2, 2006, Portfolio Managers Keith Anderson, Scott Amero, Matthew Marra and Andrew Phillips assumed responsibility for the day-to-day management of the fixed income portfolio.

He joined BlackRock in 1991. - -------------------------------------------------------------------------------- ================================================================================ 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.

He is Chairman of the Investment Strategy Group and is responsible for global fixed income strategy, asset allocation and the overall management of client portfolios.

He joined BlackRock in 1991. - -------------------------------------------------------------------------------- ================================================================================ 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. Thomas E. Burke, CFA Portfolio Manager ================================================================================ BlackRock Global Allocation 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 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.

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. Andrew J.

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.

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 Large Cap Core Portfolio generally invests at least 80% of its net assets in a diversified portfolio of equity securities, primarily common stocks, of large cap companies included at the time of purchase in the Russell 1000 Index. ++ This unmanaged Index measures the performance of the 1,000 largest companies in the Russell 3000 Index, which represents approximately 92% of the total market capitalization of the Russell 3000 Index. The Portfolio is managed to this broad-based Index, which provides for a better comparison relative to the S&P 500 Index. Russell 1000 is a registered trademark of the Frank Russell Company. Past performance is not indicative of future results. 19 - -------------------------------------------------------------------------------- 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. ============================================================================================================================== Expenses Paid Beginning Ending Account During the Period* Annualized Account Value Value July 1, 2006 to Expense Actual July 1, 2006 December 31, 2006 December 31, 2006 Ratio - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Balanced Capital Portfolio $1,000 $1,102.10 $2.15 .41% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Bond Portfolio $1,000 $1,050.90 $2.57 .50% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Fundamental Growth Portfolio $1,000 $1,036.40 $2.23 .44% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Global Allocation Portfolio $1,000 $1,091.30 $2.55 .49% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Government Income Portfolio $1,000 $1,047.90 $2.26 .44% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock High Income Portfolio $1,000 $1,060.60 $2.58 .50% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Large Cap Core Portfolio $1,000 $1,116.70 $2.27 .43% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Money Market Portfolio $1,000 $1,024.50 $2.08 .41% - ------------------------------------------------------------------------------------------------------------------------------ ============================================================================================================================== Hypothetical (5% annual return before expenses)** - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Balanced Capital Portfolio $1,000 $1,022.86 $2.07 .41% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Bond Portfolio $1,000 $1,022.59 $2.54 .50% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Fundamental Growth Portfolio $1,000 $1,022.74 $2.21 .44% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Global Allocation Portfolio $1,000 $1,022.46 $2.47 .49% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Government Income Portfolio $1,000 $1,022.89 $2.23 .44% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock High Income Portfolio $1,000 $1,022.59 $2.54 .50% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Large Cap Core Portfolio $1,000 $1,022.76 $2.17 .43% - ------------------------------------------------------------------------------------------------------------------------------ BlackRock Money Market Portfolio $1,000 $1,023.04 $2.08 .41% - ------------------------------------------------------------------------------------------------------------------------------ * Expenses for each Portfolio are equal to the annualized expense ratio, multiplied by the average account value over the period, multiplied by 182/365 for BlackRock Balanced Capital Portfolio, BlackRock Fundamental Growth Portfolio, BlackRock Global Allocation Portfolio and BlackRock Large Cap Core Portfolio, and 183/365 for BlackRock Bond Portfolio, BlackRock Government Income Portfolio, BlackRock High Income Portfolio and BlackRock Money Market Portfolio (to reflect the one-half year period shown). ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year divided by 365. 20 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc.

See Notes to Financial Statements. 99 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements ================================================================================ 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. 100 - -------------------------------------------------------------------------------- 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. 101 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. 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 102 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ 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. 103 - -------------------------------------------------------------------------------- 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. 104 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ 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.

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.

Disclosure of Investment Advisory Agreement ================================================================================ BLACKROCK SERIES FUND, INC. 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 BlackRock Money Market Portfolio 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; 117 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Disclosure of Investment Advisory Agreement (Continued) ================================================================================ 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. 118 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. 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 119 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Disclosure of Investment Advisory Agreement (Continued) ================================================================================ 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. 120 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Disclosure of Investment Advisory Agreement (Continued) ================================================================================ 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. 121 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Disclosure of Investment Advisory Agreement (Continued) ================================================================================ 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 122 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Disclosure of Investment Advisory Agreement (Concluded) ================================================================================ 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. 123 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc.
