Index performance shown for illustrative purposes only. You cannot invest directly in an index. Subprime mortgage woes dominated headlines for much of 2007, spawning a widespread liquidity and credit crisis with ramifications across global markets. The Federal Reserve Board (the "Fed") stepped in to inject liquidity into the markets and bolster investor confidence, cutting the federal funds rate by 0.50% in September, 0.25% in October and 0.25% in December, which brought the target short-term interest rate to 4.25%. In taking action, the central bankers, who had long deemed themselves inflation fighters, were seeking to stem the fallout from the credit crunch and forestall a wider economic unraveling. Amid the volatility, equity markets displayed surprising resilience. Market fundamentals generally held firm, dividend payouts and share buybacks continued, and valuations remained attractive. To some extent, the credit turmoil dampened corporate merger-and-acquisition (M&A) activity, a key source of strength for equity markets, but 2007 remained a record year for global M&A nonetheless. As the returns indicate, the most recent six months were more trying, reflecting the slowing U.S. economy, a troubled housing market and a more difficult corporate earnings backdrop. Overall, large cap stocks outperformed small caps as investors grew increasingly risk averse. International markets fared better than their U.S. counterparts, benefiting from generally stronger economies. In fixed income markets, mixed economic signals and subprime fallout resulted in a flight to quality. Investors shunned bonds associated with the housing and credit markets in favor of higher-quality Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in June (its highest level in five years), fell to 4.04% by year-end, while prices correspondingly rose. The tax-exempt bond market waffled amid the economic uncertainty and concerns around the credit worthiness of bond insurers, but set a new-issuance record in 2007. A drop in municipal bond prices created buying opportunities, and the heightened supply was generally well absorbed. 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 2007 and our 10 predictions for 2008, please ask your financial professional for a copy of "What's Ahead in 2008: An Investment Perspective," or view it online at www.blackrock.com/funds. As always, we thank you for entrusting BlackRock with your investment assets, and we look forward to continuing to serve you in the new year and beyond.

Portfolio Management Commentary ================================================================================ BlackRock Balanced Capital Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio posted a +5.64% return for the year ended December 31, 2007, while the Portfolio's benchmarks, the S&P 500 Index and the Lehman Brothers U.S. Aggregate Bond Index, posted returns of +5.49% and +6.79%, respectively. Asset allocation proved unfavorable, and bonds underperformed their benchmark while equities outpaced the S&P 500 Index. What factors influenced performance? o Within the equity portfolio, our underweight position and good stock selection in financials was the primary contributor to performance. We benefited from strong performance in The Bank of New York Mellon Corp. and Prudential Financial, Inc., and from avoiding many of the troubled bank and brokerage stocks. Good stock selection in the energy sector also aided results, led by Murphy Oil Corp. and Weatherford International Ltd. These areas of strength more than offset poor stock selection in information technology (IT), with particular weakness in Micron Technology, Inc. and Sun Microsystems, Inc. and our avoidance of strong-performing Apple Inc. and Google, Inc. An underweight in utilities also impaired performance, as this was one of the market's strongest sectors in 2007. o Within the fixed income portfolio, an overweight to mortgage-related securities detracted from performance, while an underweighting and good security selection among corporate bonds proved advantageous. Describe recent Portfolio activity. o Within the equity portfolio, we increased our overweight position in IT and altered several individual positions within the sector. We reduced holdings in Accenture Ltd., Applied Materials, Inc., Juniper Networks, Inc. and Sun Microsystems on relative price strength, added to positions in Hewlett-Packard Co., Intersil Corp., Microsoft Corp. and Yahoo! Inc., and established positions in Broadcom Corp., Micron Technology and Texas Instruments, Inc. We believe these companies' financial strength, international exposure and promising new product cycles should prove beneficial amid the current market uncertainty. o We reduced exposure to financials, concentrating on companies we believe have sound competitive positions and in whose managements we have high confidence. We trimmed positions in Citigroup, Inc. and ACE Ltd. and eliminated Genworth Financial, Inc., Fannie Mae and Wells Fargo & Co., while adding to American International Group, Inc., JPMorgan Chase & Co. and Prudential Financial, Inc.. We increased exposure to health care, largely by adding to positions in Bristol-Myers Squibb Co., Pfizer, Inc. and Wyeth. o Within fixed income, we increased exposure to high-quality bonds in the residential and commercial mortgage markets as credit spreads widened. We also reduced our underweighting to the corporate market through selected additions there. Describe Portfolio positioning at period-end. o As a percentage of total investments, the Portfolio ended the year invested 52.4% in equities, 45.3% in fixed income and 2.3% in cash equivalents. o While uncertainty over the pace of economic and corporate earnings growth is likely to persist in early 2008, we view the associated decline in share prices opportunistically and will look to increase our exposure to equities in general and cyclical stocks in particular. As expectations and valuations continue to fall, we see an attractive opportunity to purchase shares in above-average companies with strong competitive positions, favorable financial characteristics and solid managements at or near record-low valuations. Bonds, meanwhile, look increasingly expensive as interest rates are low and inflation-adjusted yields are well below historical averages, limiting their return potential. 2 ================================================================================ BlackRock Fundamental Growth Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio significantly outperformed the benchmark S&P 500 Citigroup Growth Index and the broader S&P 500 Index for the fiscal year ended December 31, 2007 with a return of +19.83% compared to returns of +9.13% and +5.49% for the Indexes, respectively. What factors influenced performance? o The past year was a volatile one for equities, with the slowdown in U.S. housing and turmoil in the subprime mortgage market touching off implications across global markets. An investor flight to quality ensued, ultimately benefiting larger-cap, growth-oriented stocks, which outperformed their smaller-cap and value-oriented counterparts. o The Portfolio's outperformance of its benchmark is attributed primarily to successful security selection. In addition, market conditions favored the Portfolio's large-cap growth style positioning, especially in the second half of the year. Holdings within the materials, health care and financial sectors were particularly favorable. Names that contributed to performance included Intuitive Surgical, Inc., Monsanto Co., National Oilwell Varco, Inc., Google, Inc. and Jacobs Engineering Group, Inc. o An underweight to consumer staples was marginally negative in the period, as was certain stock selection in the consumer discretionary sector. Particular names that detracted from performance included Akamai Technologies, Inc., Comcast Corp., Starbucks Corp. and Zimmer Holdings, Inc. An underweight in Exxon Mobil Corp. also detracted. Describe recent Portfolio activity. o Most notably, we reduced exposure to the consumer discretionary sector in 2007, while adding to select consumer staples holdings. Portfolio exposure to the financials sector also was reduced, while health care and industrials holdings were increased. Describe Portfolio positioning at period-end. o In our view, concerns over conditions in the credit and financing markets are certain to have an ongoing negative impact on the U.S. housing market. This may, in turn, have an adverse affect on consumer spending, resulting in an eventual drag on the economy. At the same time, most other global economies continue to experience strong rates of growth, providing some balance to the overall global demand picture. Taken together, we are more cautious in our outlook and continue to monitor market conditions to determine if they may pose a more serious threat to economic growth in 2008. o Although this current environment may challenge broader market earnings growth over time, we believe it should provide a relatively attractive investment environment for select larger company growth stocks going forward. At the end of the period, the Portfolio had overweight positions in the materials, industrials, health care and consumer staples sectors, while maintaining underweights in the energy and consumer discretionary sectors. ================================================================================ BlackRock Global Allocation Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio significantly outperformed its Reference Portfolio and the all-equity benchmark for the fiscal year ended December 31, 2007, as the Portfolio returned +17.96%, exceeding the +10.30% return of its Reference Portfolio and +11.32% return of the broad-based, all-equity benchmark, the Financial Times Stock Exchange (FTSE) World Index. The Portfolio invests in both equities and bonds; therefore, the Reference Portfolio provides a truer representation of the Portfolio's composition and a more comparable means for measurement. What factors influenced performance? o The Portfolio's outperformance is largely attributed to its underweight and stock selection in the U.S., along with favorable overweights in India and Brazil. Overweights and strong stock selection in Asia (ex-Japan), notably China, Hong Kong, South Korea and Singapore, also contributed to returns. o From a sector perspective, the Portfolio's overweights in energy, industrials and materials, and underweight in financials, coupled with favorable stock selection within all of these sectors, enhanced returns. o Within the fixed income portfolio, performance benefited from investments in both nominal U.S. Treasury issues and U.S. Treasury Inflation Protected 3 Securities (TIPS), as a flight to quality in the fixed income markets resulted in the increase of U.S. government bond prices. An underweight to European and Asian sovereign debt also proved advantageous. o Detracting moderately from the Portfolio's relative performance was its overweight position in Japanese equities, as Japan's equity markets declined, and stock selection in the information technology and telecommunication services sectors. Describe recent Portfolio activity. o During the year, the Portfolio's overall equity allocation increased modestly from 55% of net assets to 57%. Within equities, increases in North America (+6.2%) were partially offset by decreases in European (-3.0%) and Asian (-1.3%) equities. o On a sector basis, weightings were increased in materials (+3.0%), energy (+2.3%) and consumer staples (+1.3%), while weightings were decreased in financials (-3.2%), telecommunication services (-0.8%) and consumer discretionary (-0.7%). o The Portfolio's allocation to fixed income increased from 32% of net assets to 34%, mainly due to increases in Asian (+1.4%) and European (+1.3%) bonds. Reflecting the above changes, the Portfolio's cash equivalent holdings decreased from 13% of net assets to 9%. Describe Portfolio positioning at period-end. o Compared to its Reference Portfolio, the Portfolio ended the period moderately underweight equities (-2.6%), underweight fixed income (-5.8%) and, consequently, overweight cash equivalents (+8.4%). o Within the equity segment, the Portfolio is significantly underweight U.S. stocks (-10.8%), overweight Asia (+9.7%), notably Japan, and slightly underweight Europe (-2.9%). On a sector basis, the Portfolio is overweight materials (+3.0%), energy (+2.3%), industrials (+1.5%) and telecommunication services (+0.9%). The Portfolio's largest sector underweights include consumer discretionary (-2.8%), information technology (-2.1%), financials (-1.8%) and health care (-0.8%). o The Portfolio remains underweight in fixed income, as yields appear unattractive relative to the risks of higher inflation and higher long-term interest rates. As for currency exposure, the Portfolio is significantly underweight the U.S. dollar (-15.0%), moderately underweight the British pound (-3.4%) and the euro (-2.5%), and overweight the Japanese yen (+4.3%), Brazilian real (+3.3%), Swiss franc (+3.2%) and several Asian currencies, including the Indian rupee (+2.3%) and the Singapore dollar (+1.7%). ================================================================================ BlackRock Government Income Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio underperformed its benchmark for the fiscal year ended December 31, 2007, as the Portfolio returned +5.32% as compared to the +8.34% return of its composite index (50% Lehman Brothers Mortgage-Backed Securities Index and 50% Merrill Lynch U.S. Treasury Securities). What factors influenced performance? o Financial markets were highly volatile during the year as fears spread about which investments might have exposure to the troubled subprime mortgage market. The liquidity of mortgage-backed securities began drying up, which led to a wider liquidity crisis as banks restricted their short-term lending. Fundamentally, most spread product remained fairly sound, but the lack of buyers caused spreads to widen as investors fled to the safety of Treasury issues. o The Portfolio focuses its investment on high-quality spread product (mortgage-backed securities, asset-backed securities and other structured products that generally have higher yield potential and less correlation to Treasuries). These overweight positions hurt performance amid the underlying backdrop. Despite our conservative, high-quality bias, the underweight to Treasuries resulted in underperformance relative to the benchmark. As the year progressed, the markets began to acknowledge the difference in quality among mortgage assets. We expect this decoupling to continue over the coming months, and believe the Portfolio is positioned to benefit from its allocations to high-quality spread product. o The primary driver of positive performance for the Portfolio was our yield curve steepening bias, a strategy that proved advantageous as short-term rates fell more than long-term rates, causing the yield curve to steepen. Describe recent Portfolio activity. o The main activity in the period was a movement from generic agency mortgage-backed securities (MBS) into high-quality non-agency MBS. Given the extreme widening in credit spreads seen across mortgage 4 assets, irrespective of quality, we were able to make purchases at attractive prices. As the market heals, we believe these securities will benefit the Portfolio, even in a depressed housing market. o We also increased the Portfolio's Treasury holdings, given our concerns about a further downturn in the economy. Describe Portfolio positioning at period-end. o At period-end, the Portfolio had a long duration relative to its benchmark and a yield curve steepening bias. Given our relatively negative view on the economy, the housing market and the lowest-quality mortgage assets, we believe aggressive Federal Reserve interest rate cuts will be warranted in the short term. This should cause a continued fall in interest rates, led by the short end of the yield curve. ================================================================================ BlackRock High Income Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio's return for the fiscal year ended December 31, 2007 compared favorably to that of its benchmark, as the Portfolio returned +2.75% compared to the return of +2.65% for the Credit Suisse High Yield Index and +2.27% for the Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index. What factors influenced performance? o Financial markets were highly volatile, particularly in the second half of the year as fears spread about which investments might have exposure to the troubled subprime mortgage market. The liquidity of mortgage-backed securities began drying up, which led to a wider liquidity crisis as banks restricted their short-term lending. The Federal Reserve Board (the "Fed") and other countries' central banks stepped in to inject liquidity into the markets and bolster investor confidence. The Fed cut its target short-term interest rate from 5.25% to 4.25% between September and year-end in an effort to offset deteriorating credit conditions in the housing market and help prevent any negative spillover in the economy. o After a strong start to the year, the flight to safety that accompanied the market turmoil hurt the high yield sector, while benefiting Treasury issues. The Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index posted a return of +2.27% for the full year, and -0.67% for the latter six months. o Good security selection in the media (non-cable) sector and our underweight position in this sector toward the end of the year was a large contributor to Portfolio performance. Our underweight position in home construction contributed as well, and our position in Freeport-McMoRan Copper & Gold, Inc. helped us to outperform in the metals sector. Finally, an overweight position in aerospace benefited Portfolio results as this sector improved toward the end of the year. o Our timing in underweighting the health care sector near the end of the year (as its performance improved), combined with poor security-specific performance, was the largest detractor from Portfolio performance. In addition, security selection in consumer products, specifically a position in True Temper Sports, Inc., negatively impacted performance. Describe recent Portfolio activity. o Over the year, the Portfolio became slightly more defensive. We reduced certain higher-risk overweights such as health care, metals and entertainment. We also increased our underweight position in financials and added slightly to the Portfolio's cash allocation. Describe Portfolio positioning at period-end. o Relative to its benchmark, the Portfolio ended the year underweight in financials, home construction and consumer-related sectors. The Portfolio stands ready to take advantage of oversold sectors, while remaining positioned for the possibility of further market turbulence during 2008. 5 ================================================================================ BlackRock Large Cap Core Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio generated strong absolute returns and outperformed its benchmark, the Russell 1000 Index, for the fiscal year ended December 31, 2007, as the Portfolio had a total return of +8.29% compared to the benchmark's return of +5.77%. What factors influenced performance? o Broadly speaking, strong performance generated by asset allocation decisions was partially offset by disappointing stock selection results. The combination of allocation and stock selection in financials, materials and health care, along with stock selection in consumer discretionary, contributed to performance. Stock selection in consumer staples and information technology yielded disappointing returns. o Within financials, the Portfolio is significantly underweight the benchmark, notably in banks, thrifts & mortgage finance and real estate investment trusts (REITs). Within materials, the Portfolio is overweight in metals, and within health care, overweight in providers & services. These allocation decisions contributed positively to the Portfolio's strong relative performance. Stock selection within health care was positive, as our longstanding preference for service providers over product companies continued to generate alpha. The biggest individual contributors to performance were Citigroup, Inc., Southern Copper Corp., Monsanto Co., The Mosaic Co., Express Scripts, Inc., Medco Health Solutions, Inc. and GameStop Corp. o Within industrials, our underweight position offset favorable results from stock selection. Similarly, positive results generated by overweighting energy and information technology were offset by poor stock selection, most notably in semiconductors and computers & peripherals. o Stock selection and an underweight position in consumer staples hindered performance. The largest individual detractors were Continental Airlines, Inc., Integrated Device Technology, Inc. and Teradyne, Inc. Additionally, lack of ownership of richly valued Google, Inc. and Apple Inc. in the early part of the reporting period hindered relative returns. In retrospect, our valuation discipline hurt results in the back half of the year when "growth at any price" was a winning strategy. Describe recent Portfolio activity. o During the period, we increased the Portfolio's exposure to the industrials and health care sectors. The largest purchases included American International Group, Inc. ConocoPhillips, UnitedHealth Group, Inc., Eli Lilly & Co. and Dell, Inc. o We reduced exposure to financials, consumer discretionary and consumer staples. The largest sales included Citigroup, Johnson & Johnson, Schering-Plough Corp. and United States Steel Corp. Describe Portfolio positioning at period-end. o Relative to its benchmark, the Portfolio ended the year overweight in information technology, health care and energy, and underweight in financials, consumer staples, utilities and telecommunication services. o We believe stocks are now more susceptible to economic and earnings disappointments than during the initial stages of the Federal Reserve Board's (the "Fed") easing cycle. However, we believe more monetary relief should be in the pipeline, as economic conditions warrant further stimulus. Importantly, we do not believe inflation stands in the way of more Fed interest rate cuts. As the economic data worsens, reflation should strengthen as the dominant market force, setting the stage for higher valuations. 6 ================================================================================ BlackRock Total Return Portfolio ================================================================================ How did the Portfolio perform? o The Portfolio underperformed the benchmark for the fiscal year ended December 31, 2007, as the Portfolio had a total return of +4.47% compared to the +6.97% return for the Lehman Brothers U.S. Aggregate Bond Index. What factors influenced performance? o One of largest detractors from performance was our overweight to high-quality spread assets, particularly AAA-rated commercial mortgage-backed securities (CMBS), as well as agency mortgage pass-throughs, asset-backed securities (ABS) and other mortgage-related product. Despite their high quality, these assets suffered amid fallout from the subprime mortgage scare. Generalized concerns over the mortgage market, coupled with lack of liquidity and the liquidation by investors of all mortgage-related assets, caused the underperformance. Our exposure to European government bonds and below-investment-grade bonds also hindered the Portfolio's relative results for the year. o On the positive side, an underweight exposure to corporate bonds, and successful security selection within the corporate sector, benefited the Portfolio's relative performance. In addition, we had positioned the Portfolio for a steepening yield curve in the second half of the year, a move that proved advantageous as short-term rates fell more than long-term rates and the curve steepened. An underweight in agency debentures benefited the Portfolio as well. Describe recent Portfolio activity. o On December 10, 2007, the Portfolio changed its name from BlackRock Bond Portfolio to BlackRock Total Return Portfolio. As of the same date, with shareholder approval, the Portfolio changed its investment objective to the following: to maximize total return, consistent with income generation and prudent investment management. o As spread sectors underperformed across the fixed income markets, we used this as an opportunity to increase exposure to high-quality mortgage product, moving from an underweight position in mortgages at the start of 2007 to a significant overweight by year-end. In addition, during late third quarter-early fourth quarter, we started to decrease our underweight to investment-grade corporate bonds as the valuations of lower-quality assets began to appear more attractive. o We maintained the yield curve steepening bias, but kept duration relatively close to that of the index. We had a small allocation to below-investment-grade securities and global government bonds. Specifically, we had a roughly 2% allocation to high yield assets throughout the year, and maintained positions in European government bonds and the Japanese yen. Describe Portfolio positioning at period-end. o At year-end, the Portfolio was underweight in U.S. Treasury issues, U.S. agency securities and corporate securities, although we closed the gap in the corporate sector somewhat. The Portfolio maintained its notable overweights in high-quality, short-duration spread product, including mortgage pass-through securities, CMBS and ABS. In general, we find high-quality spread-related assets to be an attractive investment, offering yields beyond those provided by Treasury securities alone but without the risk associated with corporate bonds. Although some areas of the corporate market are attractive, lingering concerns about the economy cause us to be less positive on corporate credit overall. 7 - -------------------------------------------------------------------------------- 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 expense example below (which is based on a hypothetical investment of $1,000 invested on July 1, 2007 and held through December 31, 2007) 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 table 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 table also 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 hypothetical 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, 2007 to Expense Actual July 1, 2007 December 31, 2007 December 31, 2007 Ratio -

See Notes to Financial Statements. 77 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements ================================================================================ 1. Significant Accounting Policies: BlackRock Series Fund, Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company, offering eight separate portfolios (referred to as the "Portfolios" or individually as a "Portfolio"). 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, effective April 2, 2007, short-term investments are valued at amortized cost, which approximates market value. Prior to April 2, 2007, portfolio securities with remaining maturities of greater than 60 days, for which market quotations were readily available, were valued at market value. As securities transitioned from 61 to 60 days to maturity, the difference between the valuation existing on the sixty-first day before maturity and maturity value was amortized on a straight-line basis to maturity. BlackRock Balanced Capital Portfolio, BlackRock Fundamental Growth Portfolio, BlackRock Global Allocation Portfolio, BlackRock Government Income Portfolio, BlackRock High Income Portfolio, BlackRock Large Cap Core Portfolio and BlackRock Total Return Portfolio (formerly, BlackRock Bond 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. Effective September 4, 2007, exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade and previously were valued at the last sales price as of the close of options trading on applicable exchanges. 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. Valuation of 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. 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. 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 78 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ (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) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. (d) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). 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. (e) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (f) 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. The counterparty, for certain instruments, may pledge cash or securities as collateral. 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 covered call and put options 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 79 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ 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. Swap options are similar to options on securities except that instead of selling or purchasing the right to buy or sell a security, the writer or purchaser of the swap option is granting or buying the right to enter into a previously agreed upon interest rate swap agreement at any time before the expiration of the option. Premiums received or paid from writing or purchasing options are recorded as liabilities or assets and are subsequently adjusted to the current market value of the option written or purchased. Premiums received or paid from writing or purchasing options which expire unexercised are treated by the Portfolio on the expiration date as realized gains or losses. The difference between the premium and the amount paid or received on effecting a closing purchase or sale transaction, including brokerage commission, is also treated as a realized gain or loss. If an option is exercised, the premium paid or received is added to the cost of the purchase or the proceeds from the sale in determining whether the Portfolio has realized a gain or loss on investment transactions. The main risk that is associated with purchasing swap options is that the swap option expires without being exercised. In this case, the option expires worthless and the premium paid for the swap option is considered the loss. The main risk that is associated with the writing of a swap option is the market risk of an unfavorable change in the value of the interest rate swap underlying the written swap option. Swap options may be used by the Portfolio to manage the duration of portfolio holdings in a manner similar to more generic options described above. (g) Foreign currency transactions--Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Portfolios may invest in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (h) Short sales/borrowed bonds--Each Portfolio may engage in short selling of securities as a method of managing potential price declines in similar securities owned by the Portfolio. When the Portfolio engages in short selling, it may enter into a borrowed bond agreement to borrow the security sold short and deliver it to the broker-dealer with which it engaged in the short sale. A gain, limited to the price at which the Portfolio sold the security short or pursuant to the borrowed bond agreement, or a loss, unlimited as to dollar amount, will be recognized upon the termination of a short sale or borrowed bond agreement if the market price is greater or less than the proceeds originally received. (i) Borrowed bond agreements--In a borrowed bond agreement, each Portfolio borrows securities from a third party, with the commitment that they will be returned to the lender on an agreed-upon date. Borrowed bond agreements are primarily entered into settle short positions. In a borrowed bond agreement, the Portfolio's prime broker or third party broker takes possession of cash as collateral. The Portfolio receives interest income on the cash collateral relating to the borrowed bond agreement and is obligated to pay the prime broker or third party broker payments received on such borrowed securities. The cash collateral approximates the principal amount of the bonds borrowed transaction. To the extent that the bonds borrowed transactions exceed one 80 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ business day, the value of the collateral with any counterparty is marked-to-market on a daily basis to ensure the adequacy of the collateral, if the lender defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect lateral declines or if bankruptcy proceedings are commenced with respect to the lender of the security, realization of the collateral by the Portfolio may be delayed or limited. (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 Government Income Portfolio, BlackRock High Income Portfolio and BlackRock Total Return Portfolio, dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. If the total dividends and distributions made in any tax year exceeds net investment income and accumulated realized capital gains, a portion of total distributions may be treated as a tax return of capital. Portions of the dividends paid by BlackRock Total Return 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 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. The Portfolio receives compensation as consideration for entering into the commitment to repurchase. The Portfolio must maintain liquid securities having a value not less than the repurchase price (including accrued interest) for such dollars rolls. The market value of the securities that the Portfolio is required to purchase may decline below the agreed upon repurchase price of those securities. (n) TBA commitments--Certain Portfolios may enter into to be announced ("TBA") commitments to purchase or sell securities for a fixed price at a future date. TBA commitments are considered securities in themselves, and involve a risk of loss if the value of the security to be purchased/sold declines/increases prior to settlement date, which is in addition to the risk of decline in the value of the Portfolios' other assets. Unsettled TBA commitments are valued at the current market value of the underlying securities, according to the procedures described under "Valuation of investments." (o) Asset-backed securities--Certain Portfolios invest a significant portion of its assets in securities backed by commercial or residential mortgage loans or in issuers that hold mortgage and other asset-backed securities. Please see the Schedules of Investments for these securities. Changes in economic conditions, including delinquencies and/or defaults or assets underlying these securities, can affect the value, income and/or liquidity of such positions. 81 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ (p) Bank overdraft--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. (q) Reverse repurchase agreements-- Under reverse repurchase agreements, certain Portfolios sold securities to the counterparty and agreed to repurchase them at a mutually agreed upon date and price, and may have exchanged their respective commitments to pay or receive interest. If the counterparty defaulted on its obligation, the Portfolios' ability to receive interest would be delayed or limited. Furthermore, if the Portfolios did not have sufficient client income to pay its obligation under the reverse repurchase agreement, the Portfolios would be in default and the counterparty would have been able to terminate the repurchase agreement. At the time the Portfolios entered into a reverse repurchase agreement, it would have established a segregated account with the custodian containing cash, or cash equivalents of liquid high grade debt securities having a value at least equal to the repurchase price. (r) Recent accounting pronouncements--Effective June 29, 2007, the Portfolios implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes--an interpretation of FASB Statement No. 109" ("FIN 48"). 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 investment companies, before being measured and recognized in the financial statements. Management has evaluated the application of FIN 48 to each Portfolio, and has determined that the adoption of FIN 48 does not have a material impact on the Portfolios' financial statements. Each Portfolio files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Portfolios' U.S. federal tax returns remains open for the years ended December 31, 2004 through December 31, 2006. The statute of limitations on the Portfolios' state and local tax returns may remain open for an additional year depending upon the jurisdiction. 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. The impact on the Fund's financial statement disclosures, if any, is currently being assessed. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Fund's financial statement disclosures, if any, is currently being assessed. (s) 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 $699,439 has been reclassified between paid-in capital in excess of par and accumulated distributions in excess of net investment income and $455,065 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, swap agreements, amortization methods on fixed income securities, foreign currency transactions and accounting for paydowns. These reclassifications have no effect on net assets or net asset values per share. BlackRock Fundamental Growth Portfolio $89,055 has been reclassified between undistributed net investment income and accumulated realized net capital losses and $867 has been reclassified between paid-in capital in excess of par and undistributed net investment income as a result of permanent differences attributable to foreign taxes paid, foreign currency transactions and distributions paid in excess of taxable income. These 82 - -------------------------------------------------------------------------------- BlackRock Series Fund, Inc. Notes to Financial Statements (Continued) ================================================================================ reclassifications have no effect on net assets or net asset values per share. BlackRock Global Allocation Portfolio $2,566,628 has been reclassified between undistributed net realized capital gains and accumulated 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, classification of investments, accounting for swap agreements and the characterization of expenses. This reclassification has no effect on net assets or net asset values per share. BlackRock Government Income Portfolio $715,730 has been reclassified between paid-in capital in excess of par and undistributed net investment income and $1,891 has been reclassified between undistributed net investment income and accumulated realized capital losses as a result of permanent differences attributable to distributions paid in excess of taxable income, accounting for swap agreements, amortization methods on fixed income securities and accounting for paydowns. These reclassifications have no effect on net assets or net asset values per share. BlackRock High Income Portfolio $1,755,290 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses, $69,246 has been reclassified between paid-in capital in excess of par and accumulated distributions in excess of net investment income and $5,934 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 expiration of capital loss carryforwards, distributions paid in excess of taxable income and amortization methods on fixed income securities. These reclassifications have no effect on net assets or net asset values per share. BlackRock Total Return Portfolio $388,035 has been reclassified between paid-in capital in excess of par and accumulated distributions in excess of net investment income and $30,598 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 the treatment of distributions in excess of taxable income, accounting for swap agreements, paydowns, foreign currency contracts, passive foreign investment companies and inflation indexed bonds. These reclassifications have no effect on net assets or net asset values per share. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund, on behalf of the Portfolios, has entered into an Investment Advisory Agreement with the Manager. The Fund has also entered into separate Distribution Agreements with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates ("BDI") (collectively, the "Distributor") and has adopted separate Distribution Plans with respect to each Portfolio's shares. FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate of BlackRock, Inc. Merrill Lynch and The PNC Financial Services Group, Inc. ("PNC") are the principal owners of BlackRock, Inc. The Manager is responsible for the management of the Fund's Portfolios and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee based upon the aggregate average daily value of the eight combined Portfolios' net assets at the following annual rates: .50% of the Portfolios' average daily net assets not exceeding $250 million, .45% of the next $50 million, .40% of the next $100 million, .35% of the next $400 million, and .30% of average daily net assets in excess of $800 million. For BlackRock Government Income Portfolio, BlackRock High Income Portfolio and BlackRock Total Return Portfolio, the Manager has entered into a sub-advisory agreement with BlackRock Financial Management, Inc.

Report of Independent Registered Public Accounting Firm ================================================================================ To the Shareholders and Board of Directors of BlackRock Series Fund, Inc.: We have audited the accompanying statements of assets and liabilities, including the schedules of investments, of BlackRock Series Fund, Inc. (the "Fund") comprising BlackRock Balanced Capital Portfolio, BlackRock Fundamental Growth Portfolio, BlackRock Global Allocation Portfolio, BlackRock Government Income Portfolio, BlackRock High Income Portfolio, BlackRock Large Cap Core Portfolio, BlackRock Money Market Portfolio and BlackRock Total Return Portfolio (formerly BlackRock Bond Portfolio) as of December 31, 2007, 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, 2007, 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 portfolios constituting the BlackRock Series Fund, Inc. as of December 31, 2007, 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 the 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.

(e)(1) Audit Committee Pre-Approval Policies and Procedures: The registrant's audit committee (the "Committee") has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. (e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.
