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 in the summer as the economy showed signs of weakening and the Fed paused. Notably, the Treasury curve remained inverted for much of 2006. The 10-year Treasury yield 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, 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. BlackRock Equity Dividend Portfolio A Discussion With Your Portfolio Manager 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 Equity Dividend Portfolio's (formerly Mercury Equity Dividend Portfolio) Class I Shares posted a total return of +19.48%. For the same period, the benchmark Standard & Poor's 500 (S&P 500) Index returned +15.79% and the Lipper Equity Income Funds (Variable Products) category had an average return of +17.98%. (Funds in this Lipper category seek relatively high current income and growth of income by investing 60% or more of their assets in dividend-paying equity securities.) Global equity markets posted strong gains in 2006 as the Federal Reserve Board (the Fed) concluded, at least for now, its rate-raising activities. The U.S. economy downshifted with the very significant slowdown in housing leading the way. Corporate profit growth rose a double-digit percentage for an unprecedented fifth year in a row. Commodity price volatility increased significantly, with an early year run-up followed by a mid-year pullback. Most of the year featured an inverted yield curve as the Fed took its market rate up to 5.25%, while the 10-year Treasury note yield spent much of the year between 4.5% and 5%. Once again, non-U.S. markets, with the notable exception of Japan, outperformed the United States as the U.S. dollar resumed its weakness. While overall the year was a good one for equities, the first significant correction since 2002 enabled a change in leadership from smaller-cap, lower-quality, more cyclical stocks to larger-cap, higher-quality, more predictable stocks. After a brief mid-year scare, inflation pressures remained fairly low around the world, which was good news, especially in light of the unprecedented run-up in industrial commodity prices. In that regard, oil prices set a new all-time high in the summer, but corrected noticeably during the fall, giving further support to the equity market rally in the second half of 2006. The year also featured unprecedented share buy-backs and merger-and-acquisition (M&A) activity as well as a switch in Congress from Republican to Democratic leadership. 2006 ended with the world awash in liquidity, global growth still quite strong despite the U.S. slowdown, record-high U.S. profitability, inflation and interest rates fairly low and confidence levels relatively strong. The Portfolio outperformed its benchmark, the S&P 500 Index, and its comparable Lipper category average for the 12-month period. The Portfolio's comparative return benefited most from an overweight in energy, underweights in information technology and health care, and stock selection in the industrials, consumer staples and consumer discretionary sectors. The primary positive contributors in the industrials sector were our positions in Deere & Co., a manufacturer of agricultural and commercial equipment, and Raytheon Co., an aerospace and defense company. Our holding in Diageo Plc, a U.K. producer and distributor of beer and wine, enhanced the Portfolio's return in the consumer staples sector. Within the consumer discretionary sector, our holdings in CBS Corp., a media company, and Husqvarna AB, a Swedish manufacturer of lawn and garden equipment that is not a constituent of the S&P 500 Index, enhanced Portfolio results. The main negative contributor to the performance versus the benchmark was the Portfolio's sizeable cash position in an environment of generally rising equity markets. Adverse stock selection in energy also detracted from the relative return. The most notable negative contributors included our positions in Murphy Oil Corp., an oil and gas refining and marketing company; Peabody Energy Corp., a coal mining company that is not represented in the Index; and Exxon Mobil Corp., which performed well during the year. An underweight in the financials sector detracted slightly from the relative performance. What changes were made to the Portfolio during the period? During the first six months of 2006, we increased the Portfolio's weighting in integrated oil companies, adding to our existing positions in Chevron Corp. and Marathon Oil Corp. We also initiated a holding in Occidental Petroleum Corp. following the reduction of our position in EnCana Corp., which is leveraged to natural gas. Later in the year, we increased the Portfolio's exposure to the health care sector. After several quarters of underperformance, the share prices of pharmaceutical company stocks appeared to be discounting generic competition and litigation risks, and the stocks provided attractive yields. We also added to our holdings in Bank of America Corp. and JPMorgan Chase & Co. in financials, but the 2 Portfolio's sector weight did not increase, as we sold our shares in PNC Financial Services Group, Inc. We received cash for our Falconbridge Ltd. shares following its acquisition by Xstrata Plc, and used proceeds to establish new positions in Verizon Communications, Inc. and AT&T Inc. in the telecommunication services sector and in General Electric Co. in the industrials sector. Toward the end of 2006, we increased the Portfolio's weighting in integrated oil companies in an effort to be more defensive during the upcoming year, which we believe should see a moderation in energy prices and some headwinds to oil company earnings. We added to our holdings in Exxon Mobil Corp. and Chevron Corp., while reducing our weighting in ConocoPhillips and liquidating our holding in EnCana Corp., a natural gas exploration and production company. We also shifted our exposure to telecommunication services, reducing our positions in Verizon Communications, Inc. and Telus Corp., adding to our holding in AT&T Inc., and initiating positions in Manitoba Telecom Services, Inc., Windstream Corp. and Vodaphone Group Plc, as well as ITC Holdings Corp., a telecommunications tower operator. We also increased the Portfolio's weighting in the financials sector, where we added to our existing holdings in Bank of America Corp., Chubb Corp. and JPMorgan Chase & Co. Finally, we increased exposure to information technology with the purchase of Microsoft Corp., which we believe will benefit from its long-delayed release of the Vista operating system. How would you characterize the Portfolio's position at the close of the period? At December 31, 2006, the Portfolio's largest sector allocations were in the energy, financials, materials and utilities sectors. The Portfolio was considerably overweight versus the S&P 500 Index in materials, energy and utilities. The Portfolio's major underweights included information technology, health care, financials and consumer discretionary. We maintain our focus on companies, industries and sectors that we believe will benefit from strong growth in global demand and limited additions to productive capacity due to a combination of impediments to bringing on new projects. We remain confident that the long-term earnings power of these companies is not exclusively dependent on the spot price of commodities, which have experienced significant speculative inflows. We believe the stability of their operations, as demonstrated by their balance sheets, dividend history and forward earnings estimates, is not being reflected accurately by short-term fluctuations in their stock prices and will be more highly valued in the mid to longer term. We remain cautious on sectors that are exposed to the consumer, given reduced purchasing power from rising healthcare and utility costs, as well as potential negative wealth effects from the slowing housing market.

BlackRock Equity Dividend Portfolio Disclosure of Expenses Shareholders of this 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, distribution fees including 12b-1 fees, and other Fund 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 the 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 the 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 During the Period* Account Value Account Value July 1, 2006 to July 1, 2006 December 31, 2006 December 31, 2006 ================================================================================================================ Actual ================================================================================================================ Class I $1,000 $1,092.80 $4.90 - ---------------------------------------------------------------------------------------------------------------- Class II $1,000 $1,092.80 $5.11 - ---------------------------------------------------------------------------------------------------------------- Class III $1,000 $1,091.90 $5.37 ================================================================================================================ Hypothetical (5% annual return before expenses)** ================================================================================================================ Class I $1,000 $1,020.21 $4.73 - ---------------------------------------------------------------------------------------------------------------- Class II $1,000 $1,020.01 $4.94 - ---------------------------------------------------------------------------------------------------------------- Class III $1,000 $1,019.76 $5.19 - ---------------------------------------------------------------------------------------------------------------- * For each class of the Portfolio, expenses are equal to the annualized expense ratio for the class (.94% for Class I, .98% for Class II and 1.03% for Class III), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). All of the outstanding shares of Class II and Class III were owned by an affiliated entity and did not accrue their distribution fees (12b-1 fees) for a portion of the period. If the distribution fees were accrued for the entire period, the actual expense ratios would have been approximately 1.09% and 1.19%, the actual expenses paid would have been approximately $5.69 and $6.21, and the hypothetical expenses paid would have been approximately $5.49 and $5.99 for Class II and Class III, respectively. ** 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. 6 BlackRock Series Fund, Inc.

BlackRock Equity Dividend Portfolio Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, FAM Series Fund, Inc. and Mercury Equity Dividend Portfolio were renamed BlackRock Series Fund, Inc. (the "Fund") and BlackRock Equity Dividend Portfolio (the "Portfolio"), respectively. The Fund is an open-end management investment company that is comprised of fourteen separate portfolios. This report relates to six of the Fund's Portfolios, all of which offer three classes of shares to the Merrill Lynch Life Insurance Company, ML Life Insurance Company of New York (indirect, wholly owned subsidiaries of Merrill Lynch & Co., Inc. ("Merrill Lynch")), and other insurance companies that are not affiliated with Merrill Lynch, for their separate accounts to fund benefits under certain variable annuity and variable life insurance contracts. The Portfolio is classified as "diversified," as defined in the Investment Company Act of 1940, as amended. Class I, Class II and Class III Shares have equal voting, dividend, liquidation and other rights, except that only shares of the respective classes are entitled to vote on matters concerning only that class. In addition, Class II and Class III Shares bear certain expenses related to the distribution of such shares. The Portfolio'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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Portfolio. (a) Valuation of investments -- Equity securities held by the 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 over-the-counter ("OTC") market, 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 market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Portfolio from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., believes that this method no longer produces fair valuations. 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. The Portfolio employs pricing services to provide certain securities prices for the Portfolio. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including valuations furnished by the pricing services retained by the Portfolio, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Portfolio under the general supervision of the Fund's Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. 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 Portfolio's 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 18 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 Portfolio's 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 the Manager using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) Derivative financial instruments -- The Portfolio 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 the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Portfolio 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 financial 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 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 Options -- The Portfolio may write and purchase call and put options. When the 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 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 Forward foreign exchange contracts -- The Portfolio 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. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets and liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Portfolio invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes -- It is the Portfolio'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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. 19 (f) Dividends and distributions -- Dividends and distributions paid by the Portfolio are recorded on the ex-dividend dates. (g) Expenses -- Certain expenses have been allocated to the individual portfolios in the Fund on a pro rata basis based upon the respective aggregate net asset value of each portfolio included in the Fund. (h) Securities lending -- The Portfolio 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 receives 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. (i) Offering costs -- Adjustments to offering costs were expensed in the current period. (j) 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 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 the Portfolio's financial statements has not been determined. (k) 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, during the current year, $2,475 has been reclassified between paid-in capital in excess of par and accumulated distributions in excess of net investment income and $563 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 non-deductible expenses and foreign currency transactions. These reclassifications have no effect on net assets or net asset values 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 Portfolio, approved a new Investment Advisory Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became 20 effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate 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 Portfolio. For such services, the Portfolio pays a monthly fee at the annual rate of .60% of the average daily value of the Portfolio's net assets. The Manager (and previously MLIM) has agreed to voluntarily waive its fees and reimburse for other Portfolio expenses so that the total annual portfolio operating expenses do not exceed .94%, exclusive of distribution fees. The Manager may discontinue or reduce this waiver at any time without notice. For the year ended December 31, 2006, MLIM and the Manager earned, waived and reimbursed fees as follows: - -------------------------------------------------------------------------------- MLIM The Manager - -------------------------------------------------------------------------------- For the Period For the Period January 1, 2006 to September 30, 2006 September 29, 2006 to December 31, 2006 - -------------------------------------------------------------------------------- Fees earned .......................... $ 16,248 $ 6,846 Waiver ............................... $(16,248) $ (6,846) Reimbursement ........................ $(12,950) $ (4,849) - -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a monthly fee that is a percentage of the management fee paid by the Portfolio to the Manager. Pursuant to the Distribution Plans adopted by the Fund, in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Portfolio pays the Distributor an ongoing distribution fee each month at the annual rate of .15% and .25% of the average daily value of the Portfolio's Class II and Class III net assets, respectively. Class II and Class III commenced accruing the distribution fee on September 30, 2006. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund also has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund and the Portfolio, invest cash collateral received by the Portfolio for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2006, the Portfolio reimbursed MLIM and the Manager $62 and $18, respectively, for certain accounting services. In addition, MLPF&S received $226 in commissions on the execution of portfolio security transactions for year ended December 31, 2006. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or directors of the Fund were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2006 were $1,134,147 and $219,299, respectively. 4. Capital Share Transactions: Net increase in net assets derived from capital share transactions was $1,266,714 and $2,981,349 for the years ended December 31, 2006 and December 31, 2005, respectively. 21 Transactions in capital shares for each class were as follows: - ------------------------------------------------------------------------------- Class I Shares for the Year Ended Dollar December 31, 2006 Shares Amount - ------------------------------------------------------------------------------- Shares sold ............................... 98,892 $1,242,411 Shares issued to shareholders in reinvestment of dividends, distributions and return of capital .............................. 10,317 131,122 ------- ---------- Total issued .............................. 109,209 1,373,533 Shares redeemed ...........................

Short-Term Borrowings: The Fund, on behalf of the Portfolio, along with certain other funds managed by the Manager and its affiliates (or MLIM and its affiliates), is party to a $500,000,000 credit agreement with a group of lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms. The Portfolio pays a commitment fee of .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Portfolio's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended December 31, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2006 and December 31, 2005 was as follows: - -------------------------------------------------------------------------------- 12/31/2006 12/31/2005 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income .......................... $ 69,637 $ 68,815 Long-term capital gain ................... 61,248 -- Tax return of capital .................... 311 -- -------- -------- Total taxable distributions ................ $131,196 $ 68,815 ======== ======== As of December 31, 2006, the components of accumulated earnings on a tax basis were as follows: - -------------------------------------------------------------------------------- Undistributed ordinary income--net .......................... $ -- Undistributed long-term capital gains--net .................. -- -------- Total undistributed earnings--net ........................... -- Capital loss carryforward ................................... -- Unrealized gains--net ....................................... 867,812* -------- Total accumulated earnings--net ............................. $867,812 ======== - -------------------------------------------------------------------------------- * The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales and the deferral of post-October currency and capital losses for tax purposes. 7. Subsequent Event: On January 31, 2007, the Fund's Board of Directors has approved a Plan of Liquidation, Dissolution and Termination contingent upon contract holder approval of a Plan of Substitution. A preliminary proxy statement has been filed with the Securities and Exchange Commission and its review is pending. 22 BlackRock Series Fund, Inc. BlackRock Equity Dividend Portfolio Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock Series Fund, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of BlackRock Equity Dividend Portfolio of BlackRock Series Fund, Inc. (formerly Mercury Equity Dividend Portfolio of FAM Series Fund, Inc.) (the "Fund") as of December 31, 2006, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two 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 audit 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. 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 BlackRock Equity Dividend Portfolio of BlackRock Series Fund, Inc. as of December 31, 2006, the results of its operations for the year then ended and the changes in its net assets and its financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BlackRock Global SmallCap Portfolio A Discussion With Your Portfolio Managers 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 SmallCap Portfolio's (formerly Mercury Global SmallCap Portfolio) Class I Shares had a total return of +17.98%. For the same period, the benchmark Morgan Stanley Capital International (MSCI) World Small Cap Index returned +17.20% and the broader MSCI World Index returned +20.07%. In what was a very volatile year, global small cap stocks managed to turn in solid performance. Strong investment flows into international equities, healthy economic growth, an easing of energy prices, relatively low interest rates and reasonable valuations created a favorable environment for these stocks. A market pullback between May and August, which was largely prompted by investor fears of slowing economic growth and rising interest rates, served to neutralize what had been a very good start to the year. Nevertheless, the Federal Reserve's (the Fed's) long-anticipated break from interest rate increases, falling energy prices and a strengthening consumer provided catalysts for a rebound in the last four months of the year. European markets performed very well during the 12-month period, led by the United Kingdom (+43.06%), Switzerland (+48.11%) and France (+42.31%). The small cap market in the United States also performed well, but trailed its European counterparts with a return of +14.51%. Japan was the clear laggard, returning -16.08%. With the exception of the very small weighting in Luxembourg, Japan was the only country in the index to post negative returns. This poor performance came on the heels of excellent gains in 2005. Sectors most leveraged to the industrialization of emerging countries and global economic growth delivered the strongest performance in 2006. Among the major sectors, materials (+37.0%) and energy (+30.9%) produced the largest returns, as robust demand for relatively scarce natural resources, including oil, natural gas and metals such as copper and aluminum, drove many commodity prices higher at points during the year. In addition, the industrials sector also showed strength, rising 19.0% as industrialization in emerging markets elevated demand for machinery and construction and engineering services. All sectors posted positive returns, underscoring the breadth of participation in the market rally. Information technology (+6.6%) and health care (+10.1%), although positive, were the worst-performing sectors during the year. What factors most influenced Portfolio performance during the year? The Portfolio appreciated significantly in 2006 and outperformed the MSCI World Small Cap Index. Stock selection in the consumer discretionary and industrials sectors produced strong absolute and relative returns, and more than offset relative weakness in the energy sector. In addition, sector allocation proved modestly positive as the Portfolio's underweight position in the consumer discretionary sector and overweight position in materials added value during the period. Stock selection in the consumer discretionary sector proved to be a major contributor to the Portfolio's outperformance in 2006. The success was spread across numerous countries and industries within the sector. Apparel manufacturers Polo Ralph Lauren Corp. (U.S.) and Valentino Fashion Group SpA (Italy) performed particularly well, as did Game Group Plc, a video game retailer in the U.K., and Clear Media Ltd., a Hong Kong-based creator of outdoor advertising in China. In addition, the Portfolio's underweight position in the sector boosted relative returns as higher energy prices for consumers hampered their spending during the period. In the industrials sector, Vestas Wind Systems A/S produced the greatest gain, and was the top-performing holding in the Portfolio during 2006. This Danish manufacturer of wind turbines has benefited from the increasing attention being paid to alternative forms of energy. Suntech Power Holdings Co. Ltd., a producer of solar panels based in China, also benefited from this theme. Elsewhere in industrials, Shenzhen Expressway Co. Ltd., a Chinese company that constructs and manages highways, performed very well as China continues to grow and become more industrialized. In Europe, Enodis Plc, a British supplier of commercial food equipment, and Ryanair Holdings Plc, an Irish low-cost airline, also boosted the Portfolio's performance. The energy sector continued to be quite volatile, with the prices of crude oil and natural gas trading in wide ranges during the year. While this sector of the Portfolio generated positive returns, our energy 24 holdings collectively underperformed the benchmark. Our exposure to natural gas-related names, such as Brigham Exploration Co., Newpark Resources, Inc. and Grey Wolf, Inc. in the United States, negatively affected performance. From a geographic perspective, investment decisions in the Pacific region contributed to the Portfolio's results, overcoming underperformance in the United States. Within the index, Japan was clearly the worst-performing country. Our substantial underweight in the country, combined with positive stock selection, helped to generate excess returns for the Portfolio. Also in the Pacific region, our investments in China and Hong Kong contributed significantly, with our holdings in these regions collectively rising more than 80%. What changes were made to the Portfolio during the period? Sector allocations remained relatively stable during the year, and there were no major changes to sector positioning. We modestly increased our absolute and relative weightings in the telecommunication services and utilities sectors. These weightings remain very small, however, given that these companies make up a small portion of the universe. Elsewhere, we added to the consumer discretionary sector, while trimming our exposure to the health care sector. The modest increase in the weighting of the consumer discretionary sector was driven by bottom-up stock selection and did not reflect a change in outlook for the sector. We added a few diverse names during the year, including Guitar Center, Inc., a retailer of musical instruments and supplies in the United States, and LKQ Corp., a re-seller of used auto parts in the U.S. We modestly reduced the Portfolio's allocation in health care, thereby trimming the overweight positioning held at the beginning of the year. We eliminated two pharmaceutical holdings, Sciele Pharmaceuticals, Inc. and Noven Pharmaceuticals, Inc., after both stocks achieved notable gains. The most significant changes from a geographic perspective came in the United States and the United Kingdom, though we remain underexposed to the United Kingdom when measured against the MSCI World Small Cap Index. These increases came at the expense of Japan, where we have found it difficult to find high-growth companies at attractive valuations. In addition, we modestly reduced the Portfolio's allocation to several other European countries, such as France and Denmark. How would you characterize the Portfolio's position at the close of the period? With additions made during the past six months, the Portfolio significantly narrowed its underweight position in the United States, the largest component of the MSCI World Small Cap Index. The Portfolio ended the year underweight in the other major developed markets in the index, including the United Kingdom, Japan and Canada. We have offset these underweight positions by investing in emerging markets in Asia, Mideast-Africa and Latin America, as well as in Europe (ex-U.K.). Using our bottom-up process, we have identified many excellent investment opportunities in a diverse group of countries, including Brazil, India and South Korea. The companies in which we have invested, in our view, have brighter growth prospects than many of their peers in the developed markets and have been available at attractive prices. From a sector perspective, the Portfolio ended the period with underweight positions in the financials sector, primarily in U.S. banking, and in the consumer discretionary and industrials sectors, mainly in Japan. The Portfolio is modestly overweight in basic materials and health care. We remain confident in the future of global small cap investing. Our primary emphasis continues to be on investing in companies that exhibit strong growth characteristics at reasonable valuations.

BlackRock Global SmallCap Portfolio Disclosure of Expenses Shareholders of this 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, distribution fees including 12b-1 fees, and other Fund 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 the 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 the 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 During the Period* Account Value Account Value July 1, 2006 to July 1, 2006 December 31, 2006 December 31, 2006 ================================================================================================================ Actual ================================================================================================================ Class I $ 1,000 $1,140.30 $ 6.24 - ---------------------------------------------------------------------------------------------------------------- Class II $ 1,000 $1,139.30 $ 6.67 - ---------------------------------------------------------------------------------------------------------------- Class III $ 1,000 $1,138.40 $ 6.93 ================================================================================================================ Hypothetical (5% annual return before expenses)** ================================================================================================================ Class I $ 1,000 $1,019.07 $ 5.89 - ---------------------------------------------------------------------------------------------------------------- Class II $ 1,000 $1,018.67 $ 6.29 - ---------------------------------------------------------------------------------------------------------------- Class III $ 1,000 $1,018.42 $ 6.54 - ---------------------------------------------------------------------------------------------------------------- * For each class of the Portfolio, expenses are equal to the annualized expense ratio for the class (1.17% for Class I, 1.25% for Class II and 1.30% for Class III), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). All of the outstanding shares of Class II and Class III were owned by an affiliated entity and did not accrue their distribution fees (12b-1 fees) for a portion of the period. If the distribution fees were accrued for the entire period, the actual expense ratios would have been approximately 1.32% and 1.42%, the actual expenses paid would have been approximately $7.04 and $7.57, and the hypothetical expenses paid would have been approximately $6.64 and $7.14 for Class II and Class III, respectively. ** 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. 28 BlackRock Series Fund, Inc.

See Notes to Financial Statements. 41 BlackRock Series Fund, Inc. BlackRock Global SmallCap Portfolio Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, FAM Series Fund, Inc. and Mercury Global SmallCap Portfolio were renamed BlackRock Series Fund, Inc. (the "Fund") and BlackRock Global SmallCap Portfolio (the "Portfolio"), respectively. The Fund is an open-end management investment company that is comprised of fourteen separate portfolios. This report relates to six of the Fund's Portfolios, all of which offer three classes of shares to the Merrill Lynch Life Insurance Company, ML Life Insurance Company of New York (indirect, wholly owned subsidiaries of Merrill Lynch & Co., Inc. ("Merrill Lynch")), and other insurance companies that are not affiliated with Merrill Lynch, for their separate accounts to fund benefits under certain variable annuity and variable life insurance contracts. The Portfolio is classified as "diversified," as defined in the Investment Company Act of 1940, as amended. Class I, Class II and Class III Shares have equal voting, dividend, liquidation and other rights, except that only shares of the respective classes are entitled to vote on matters concerning only that class. In addition, Class II and Class III Shares bear certain expenses related to the distribution of such shares. The Portfolio'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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Portfolio. (a) Valuation of investments -- Equity securities held by the 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 over-the-counter ("OTC") market, 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 market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Portfolio from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., believes that this method no longer produces fair valuations. 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. The Portfolio employs pricing services to provide certain securities prices for the Portfolio. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including valuations furnished by the pricing services retained by the Portfolio, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Portfolio under the general supervision of the Fund's Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. 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 Portfolio's 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 42 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 Portfolio's 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 the Manager using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) Derivative financial instruments -- The Portfolio 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 the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Portfolio 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 financial 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 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 Options -- The Portfolio may write and purchase call and put options. When the 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 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 Forward foreign exchange contracts -- The Portfolio 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. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets and liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Portfolio invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes -- It is the Portfolio'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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Dividends and distributions -- Dividends and distributions paid by the Portfolio are recorded on the ex-dividend dates. 43 (g) Expenses -- Certain expenses have been allocated to the individual portfolios in the Fund on a pro rata basis based upon the respective aggregate net asset value of each portfolio included in the Fund. (h) Securities lending -- The Portfolio 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 receives 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. (i) Offering costs -- Adjustments to offering costs were expensed in the current period. (j) 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 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 the Portfolio's financial statements has not been determined. (k) 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, during the current year, $660 has been reclassified between paid-in capital in excess of par and distributions in excess of net investment income and $2,516 has been reclassified between undistributed realized net capital gains and distributions in excess of net investment income as a result of permanent differences attributable to non-deductible expenses, gains from the sale of stock of passive foreign investment companies, foreign currency transactions and foreign taxes paid. These reclassifications have no effect on net assets or net asset values 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 Portfolio, approved a new Investment Advisory Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Fund has also entered into separate 44 Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate 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 Portfolio. For such services, the Portfolio pays a monthly fee at the annual rate of .85% of the average daily value of the Portfolio's net assets. The Manager (and previously, MLIM) has agreed to voluntarily waive its fees and reimburse for other Portfolio expenses so that the total annual portfolio operating expenses do not exceed 1.17%, exclusive of distribution fees. The Manager may discontinue or reduce this waiver at any time without notice. For the year ended December 31, 2006, MLIM and the Manager earned, waived, and reimbursed fees as follows: - -------------------------------------------------------------------------------- MLIM The Manager -------------------------------------------- For the Period For the Period January 1, 2006 to September 30, 2006 September 29, 2006 to December 31, 2006 - -------------------------------------------------------------------------------- Fees earned ........................ $ 31,727 $ 12,752 Waiver ............................. $ (31,727) $ (12,752) Reimbursement ...................... $(115,423) $ (51,903) - -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a monthly fee that is a percentage of the management fee paid by the Portfolio to the Manager. Pursuant to the Distribution Plans adopted by the Fund, in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Portfolio pays the Distributor an ongoing distribution fee each month at the annual rate of .15% and .25% of the average daily value of the Portfolio's Class II and Class III net assets, respectively. Class II and Class III commenced accruing the distribution fee on September 30, 2006. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund also has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund and the Portfolio, invest cash collateral received by the Portfolio for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2006, the Portfolio reimbursed MLIM and the Manager $89 and $27, respectively, for certain accounting services. In addition, MLPF&S received $2,130 in commissions on the execution of portfolio security transactions for year ended December 31, 2006. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or directors of the Fund were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2006 were $6,684,197 and $5,341,666, respectively. 4. Capital Share Transactions: Net increase in net assets derived from capital share transactions was $1,928,025 and $3,686,650 for the years ended December 31, 2006 and December 31, 2005, respectively. Transactions in capital shares for each class were as follows: 45 - -------------------------------------------------------------------------------- Class I Shares for the Year Ended Dollar December 31, 2006 Shares Amount - -------------------------------------------------------------------------------- Shares sold .................................... 154,485 $ 1,862,856 Shares issued to shareholders in reinvestment of dividends and distributions ............................ 16,145 207,297 ------- ----------- Total issued ................................... 170,630 2,070,153 Shares redeemed ................................

Short-Term Borrowings: The Fund, on behalf of the Portfolio, along with certain other funds managed by the Manager and its affiliates (or MLIM and its affiliates), is party to a $500,000,000 credit agreement with a group of lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms. The Portfolio pays a commitment fee of .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Portfolio's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended December 31, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2006 and December 31, 2005 was as follows: - -------------------------------------------------------------------------------- 12/31/2006 12/31/2005 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income ...................................... $ 65,418 $ 93,909 Long-term capital gain ............................... 141,967 -- -------- -------- Total taxable distributions ............................ $207,385 $ 93,909 ======== ======== - -------------------------------------------------------------------------------- As of December 31, 2006, the components of accumulated earnings on a tax basis were as follows: - -------------------------------------------------------------------------------- Undistributed ordinary income--net .............................. $ 118,938 Undistributed long-term capital gains--net ...................... 45,262 ---------- Total undistributed earnings--net ............................... 164,200 Capital loss carryforward ....................................... -- Unrealized gains--net ........................................... 926,442* ---------- Total accumulated earnings--net ................................. $1,090,642 ========== - -------------------------------------------------------------------------------- * The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains on investments in passive foreign investment companies and the realization for tax purposes of unrealized gains (losses) on certain foreign currency contracts. 7. Subsequent Event: On January 31, 2007, the Fund's Board of Directors has approved a Plan of Liquidation, Dissolution and Termination contingent upon contract holder approval of a Plan of Substitution. A preliminary proxy statement has been filed with the Securities and Exchange Commission and its review is pending. 46 BlackRock Series Fund, Inc. BlackRock Global SmallCap Portfolio Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock Series Fund, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of BlackRock Global SmallCap Portfolio of BlackRock Series Fund, Inc. (formerly Mercury Global SmallCap Portfolio of FAM Series Fund, Inc.) (the "Fund") as of December 31, 2006, the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two 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 audit 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 BlackRock Global SmallCap Portfolio of BlackRock Series Fund, Inc. as of December 31, 2006, the results of its operations for the year then ended and the changes in its net assets and its financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BlackRock International Index Portfolio A Discussion With Your Portfolio Managers 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 International Index Portfolio's (formerly Mercury International Index Portfolio) Class I and Class II Shares had total returns of +26.00% and +25.68%, respectively. For the same period, the benchmark Morgan Stanley Capital International Europe, Australasia, Far East (MSCI EAFE) Index returned +26.34%. The MSCI EAFE Index is a free-float adjusted, market-capitalization-weighted index designed to measure equity performance of developed markets, excluding the United States and Canada. As the value of the MSCI EAFE fluctuated during the past 12 months, the Portfolio's performance generally tracked that of the index. Non-U.S. markets outperformed their U.S. counterparts for the fifth consecutive year, as the Index return illustrates. U.S. stocks, as measured by the S&P 500 Index, returned +15.79% in 2006, while the MSCI Europe Index and the MSCI Pacific Index gained 33.72% and 12.20%, respectively, in U.S.-dollar terms. Strength was especially noticeable in Europe (in both developed and emerging markets), which benefited from robust economic growth, high levels of merger-and-acquisition (M&A) activity and the significant appreciation of the euro versus the dollar. Leadership also came from many Asian markets, with the notable exception of Japan, which was hurt by struggling economic growth. Among the standouts were India's Bombay Sensex Index, which rose 47%, Hong Kong's Hang Seng Index, which advanced 34%, and most remarkably, the MSCI China A Index, which posted a +128% return. There were two major themes in global equity markets at the end of 2006. First, the bull market persisted, although volatility was present throughout the year. Second, the more cyclical markets, on average, continued to outperform, with particularly strong results from emerging markets. Japan remained an underperformer versus other global markets, notwithstanding a significant bounce toward the end of the year. The year began with solid performance across most non-U.S. market indexes, thanks to solid operational results and a generally robust corporate sector that benefited from a record pace of global M&A activity. Evidence of an economic slowdown began to mount, however, with investor sentiment taking a negative turn in the second quarter. Profit-taking, global concerns over moderating economic growth, rising energy prices, overall higher interest rates and a resurgence of inflation fears weighed on equity markets worldwide. By May, these concerns culminated in a significant broad-based market correction, where the average U.S. stock fell by about 12% and non-U.S. equities suffered even greater losses. Positive momentum did return to the market in the second half of 2006, though global economic growth moderated. Still, the prevailing growth rate in the global economy remains fairly robust, hovering right around the long-term trend rate. This reflects both the boom conditions that characterized the start of the year and the fact that the slowdown was moderate rather than abrupt. The United States was the weakest of the major regions in terms of economic growth in the second half, with third quarter 2006 gross domestic product (GDP) rising at an annual rate of 2.2%, down from the 2.6% growth rate seen in the second quarter. Economic conditions in Asia were mixed, while continental Europe and the United Kingdom exhibited only limited signs of a slowdown -- even after a period long enough for the impact of a weaker U.S. economy to filter through. Strong growth in corporate earnings and significant upward revisions to earnings expectations have buttressed the equity market since 2003. Although the rate of upgrading has slowed from the exceptionally strong levels seen in previous years, recent news from the major corporate sectors generally has been upbeat. Earnings came in ahead of expectations in the last earnings rounds in Europe, Japan and the United States, supporting the second-half rally in equities. Historic global profit growth is still around 20%. Notably, in the latter half of the year, crude oil prices collapsed after reaching an all-time high near $78 per barrel in July. As a result, headline inflation rates in many countries dropped back sharply. Central banks also were less active. In the United States, the Federal Reserve Board (the Fed) has been on hold since mid-year. Additionally, there have been fewer tightening measures in Asia, with the recent exception of India, which saw a rise in reserve requirements. The European Central Bank, on the other hand, continued its rate-normalization process and rates in the United Kingdom are likely to rise modestly. 48 Turning to regional performance, all 16 European MSCI country indexes delivered exceptional double-digit gains for the 12-month period, in U.S.-dollar terms. Key drivers of performance included record levels of M&A activity, improving European consumer sentiment, which amplified healthy measures of business confidence, as well as a significant improvement in corporate profitability that resulted from the ongoing consolidation and streamlining efforts of European businesses. The strongest-performing markets were Spain (+49.36%), Portugal (+47.37%) and Ireland (+46.81%). Markets in the Australasia/Far East region continued to perform well, although at a slower growth rate than at the beginning of 2006. For the year, Singapore gained +46.71%, Australia rose +30.86% and Hong Kong advanced +30.35%, in U.S.-dollar terms. New Zealand grew more slowly in comparison, but still posted a solid return of +16.56%. The Japanese equity market failed to keep pace with the world's biggest developed markets in 2006, despite improving economic fundamentals and robust corporate earnings. After a strong 2005, Japan's Nikkei 225 returned only 6% in 2006, primarily due to concerns that weak consumption spending could halt the nation's economic recovery. GDP in Japan has grown at an annualized rate of 1% since the spring, with the only areas of strength being exports and business investment (which is itself highly correlated with exports). Also, noticeably absent from the Japanese market is M&A activity, which has driven substantial outperformance in many other developed markets, most particularly in Europe. All global sectors in the MSCI EAFE Index posted positive double-digit returns during the annual period, in U.S.-dollar terms. The best-performing sector by far was utilities (+49.04%), driven by the preponderance of takeover activity in this area. Other leaders included materials (+32.00%), telecommunication services (+29.54%) and consumer staples (+29.42%). In terms of currency performance, despite weakening dramatically toward year-end, the U.S. dollar outperformed most major currencies in 2006, registering gains of 10.6% and 12.3% against the euro and the pound, respectively, but declining 1.0% versus the yen. What changes were made to the Portfolio during the period? Throughout the fiscal year, as changes were made to the composition of the MSCI EAFE Index, the Portfolio purchased and sold securities to maintain its objective of replicating the risks and return of the benchmark. How would you characterize the Portfolio's position at the close of the period? We believe the Portfolio remains positioned to match the risk characteristics of its benchmark, regardless of the direction of international markets. Debra L.

BlackRock International Index Portfolio Disclosure of Expenses Shareholders of this 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, distribution fees including 12b-1 fees, and other Fund 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 the 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 the 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 During the Period* Account Value Account Value July 1, 2006 to July 1, 2006 December 31, 2006 December 31, 2006 ======================================================================================================================== Actual ======================================================================================================================== Class I $ 1,000 $1,149.30 $ 3.16 - ------------------------------------------------------------------------------------------------------------------------ Class II $ 1,000 $1,147.30 $ 3.96 - ------------------------------------------------------------------------------------------------------------------------ Class III $ 1,000 $1,147.40 $ 3.59 ======================================================================================================================== Hypothetical (5% annual return before expenses)** ======================================================================================================================== Class I $ 1,000 $1,021.96 $ 2.97 - ------------------------------------------------------------------------------------------------------------------------ Class II $ 1,000 $1,021.21 $ 3.73 - ------------------------------------------------------------------------------------------------------------------------ Class III $ 1,000 $1,021.56 $ 3.38 - ------------------------------------------------------------------------------------------------------------------------ * For each class of the Portfolio, expenses are equal to the annualized expense ratio for the class (.59% for Class I, .74% for Class II, and .67% for Class III), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). All outstanding shares of Class III were owned by an affiliated entity and did not accrue its distribution fees (12b-1 fees) for a portion of the period. If the distribution fees were accrued for the entire period, the actual expense ratio would have been approximately .84%, the actual expenses paid would have been approximately $4.50, and the hypothetical expenses paid would have been $4.23 for Class III. ** 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. 52 BlackRock Series Fund, Inc.

See Notes to Financial Statements. 62 BlackRock Series Fund, Inc. BlackRock International Index Portfolio Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, FAM Series Fund, Inc. and Mercury International Index Portfolio were renamed BlackRock Series Fund, Inc. (the "Fund") and BlackRock International Index Portfolio (the "Portfolio"), respectively. The Fund is an open-end management investment company that is comprised of fourteen separate portfolios. This report relates to six of the Fund's Portfolios, all of which offer three classes of shares to the Merrill Lynch Life Insurance Company, ML Life Insurance Company of New York (indirect, wholly owned subsidiaries of Merrill Lynch & Co., Inc. ("Merrill Lynch")), and other insurance companies not affiliated with Merrill Lynch, for their separate accounts to fund benefits under certain variable annuity and variable life insurance contracts. The Portfolio is classified as "non-diversified," as defined in the Investment Company Act of 1940, as amended. Class I, Class II and Class III Shares have equal voting, dividend, liquidation and other rights, except that only shares of the respective classes are entitled to vote on matters concerning only that class. In addition, Class II and Class III Shares bear certain expenses related to the distribution of such shares. The Portfolio'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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Portfolio. (a) Valuation of investments -- Equity securities held by the 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 over-the-counter ("OTC") market, 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 market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Portfolio from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., believes that this method no longer produces fair valuations. 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. The Portfolio employs pricing services to provide certain securities prices for the Portfolio. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including valuations furnished by the pricing services retained by the Portfolio, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Portfolio under the general supervision of the Fund's Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. Generally, trading in foreign securities, 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 Portfolio's 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 63 and the close of business on the NYSE that may not be reflected in the computation of the Portfolio's 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 the Manager using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) Derivative financial instruments -- The Portfolio 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 the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Portfolio 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 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 Options -- The Portfolio may write and purchase call and put options. When the 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 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 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 Forward foreign exchange contracts -- The Portfolio 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. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets and liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Portfolio invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes -- It is the Portfolio'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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Dividends and distributions -- Dividends and distributions paid by the Portfolio are recorded on the ex-dividend dates. 64 (g) Expenses -- Certain expenses have been allocated to the individual portfolios in the Fund on a pro rata basis based upon the respective aggregate net asset value of each portfolio included in the Fund. (h) Securities lending -- The Portfolio 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 receives 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. (i) 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 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 the Portfolio's financial statements has not been determined. (j) 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, during the current year, $153 has been reclassified between accumulated distributions in excess of net investment income and paid-in capital in excess of par and $30,091 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 non-deductible expenses, gains from the sale of stock of passive foreign investment companies and foreign currency transactions. These reclassifications have no effect on net assets or net asset values 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 Portfolio, approved a new Investment Advisory Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Portfolio has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock 65 Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate 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 Portfolio. For such services, the Portfolio pays a monthly fee at the annual rate of .35% of the average daily value of the Portfolio's net assets. The Manager (and previously MLIM) has agreed to voluntarily waive its fees and reimburse for other Portfolio expenses so that the total annual portfolio operating expenses do not exceed .59%, exclusive of distribution fees. The Manager may discontinue or reduce this waiver at any time without notice. For the year ended December 31, 2006, MLIM and the Manager earned, waived and reimbursed fees as follows: - -------------------------------------------------------------------------------- MLIM The Manager -------------------------------------------- For the Period For the Period January 1, 2006 to September 30, 2006 September 29, 2006 to December 31, 2006 - -------------------------------------------------------------------------------- Fees earned ................ $ 41,165 $ 8,491 Waiver ..................... $ (41,165) $ (8,491) Reimbursement .............. $(126,595) $ (90,370) - -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a monthly fee that is a percentage of the management fee paid by the Portfolio to the Manager. Pursuant to the Distribution Plans adopted by the Fund, in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Portfolio pays the Distributor an ongoing distribution fee each month at the annual rate of .15% and .25% of the average daily value of the Portfolio's Class II and Class III net assets, respectively. Class III commenced accruing the distribution fee on September 30, 2006. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund has also retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund and the Portfolio, invest cash collateral received by the Portfolio for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2006, the Portfolio reimbursed MLIM and the Manager $310 and $87, respectively, for certain accounting services. In addition, MLPF&S earned $45 in commissions on the execution of portfolio security transactions for the year ended December 31, 2006. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or directors of the Fund were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2006 were $10,021,972 and $17,473,859, respectively. 4. Capital Share Transactions: Net increase (decrease) in net assets derived from capital share transactions was ($5,035,160) and $13,650,831 for the years ended December 31, 2006 and December 31, 2005, respectively. Transactions in capital shares for each class were as follows: - -------------------------------------------------------------------------------- Class I Shares for the Year Ended Dollar December 31, 2006 Shares Amount - -------------------------------------------------------------------------------- Shares sold ............................ 98,526 $ 1,239,921 Shares issued to shareholders in reinvestment of dividends and distributions .................... 44,186 464,747 -------- ----------- Total issued ........................... 142,712 1,704,668 Shares redeemed ........................

Short-Term Borrowings: The Fund, on behalf of the Portfolio, along with certain other funds managed by the Manager and its affiliates (or MLIM and its affiliates), is party to a $500,000,000 credit agreement with a group of lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms. The Portfolio pays a commitment fee of .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Portfolio's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended December 31, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2006 and December 31, 2005 was as follows: - -------------------------------------------------------------------------------- 12/31/2006 12/31/2005 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income .................................. $1,135,332 $ 223,612 Long-term capital gains .......................... 1,529,147 -- ---------- ---------- Total taxable distributions ........................ $2,664,479 $ 223,612 ========== ========== - -------------------------------------------------------------------------------- As of December 31, 2006, the components of accumulated earnings on a tax basis were as follows: - -------------------------------------------------------------------------------- Undistributed ordinary income--net ......................... $ 39,747 Undistributed long-term capital gains--net ................. 50,236 ---------- Total undistributed earnings--net .......................... 89,983 Capital loss carryforward .................................. -- Unrealized gains--net ...................................... 1,392,437* ---------- Total accumulated earnings--net ............................ $1,482,420 ========== - -------------------------------------------------------------------------------- * The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales and the realization for tax purposes of unrealized gains on investments in passive foreign investment companies. 7. Subsequent Event: On January 31, 2007, the Fund's Board of Directors has approved a Plan of Liquidation, Dissolution and Termination contingent upon contract holder approval of a Plan of Substitution. A preliminary proxy statement has been filed with the Securities and Exchange Commission and its review is pending. 67 BlackRock Series Fund, Inc. BlackRock International Index Portfolio Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock Series Fund, Inc.: We have audited the accompanying statement of assets and liabilities, including the summary schedule of investments, of BlackRock International Index Portfolio of BlackRock Series Fund, Inc. (formerly Mercury International Index Portfolio of FAM Series Fund, Inc.) (the "Fund") as of December 31, 2006, the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two 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 audit 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 BlackRock International Index Portfolio of BlackRock Series Fund, Inc. as of December 31, 2006, the results of its operations for the year then ended and the changes in its net assets and its financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BlackRock Mid Cap Value Opportunities Portfolio A Discussion With Your Portfolio Manager 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 Mid Cap Value Opportunities Portfolio's (formerly Mercury Mid Cap Value Opportunities Portfolio) Class I Shares had a total return of +13.32%. For the same period, the benchmark Standard & Poor's (S&P) MidCap 400 Index returned +10.32% and the Lipper Mid Cap Value Funds (Variable Products) category had an average return of +13.15%. (Funds in this Lipper category invest primarily in stocks of mid-capitalization companies that are considered to be undervalued relative to a major unmanaged stock index.) Mid cap stocks posted strong returns for the year, although the favorable absolute performance obscures sharp declines that occurred over the summer months. This summer correction spanned all capitalization ranges, investment styles and both domestic and international markets. The market retrenchment was attributed to multiple factors but, for the most part, U.S. investors were concerned that the Federal Reserve Board (the Fed) may have tightened monetary policy too aggressively. Small and mid cap stocks were particularly volatile during this time period, given their more pronounced sensitivity to changes in the overall economy. The correction also marked a subtle change in market leadership, both from a capitalization perspective and from a sector perspective. While small-cap, low-quality issues outperformed prior to the correction, large-cap, high-quality stocks demonstrated leadership coming out of the correction. In the first six months of the year, mid-cap stocks held a comfortable lead over the large cap S&P 500 Index. However, that trend shifted in the second half as investors increasingly sought out large cap names for their relative stability and more predictable earnings in an environment of moderating economic growth. With respect to sector performance, energy stocks demonstrated market leadership in the first half of the year, but weakened dramatically in the second half. An uneventful hurricane season, unusually warm fall and winter temperatures across much of the United States, and the liquidation by hedge fund Amaranth Advisors LLC of large energy positions contributed to extremely volatile crude oil and natural gas prices during the year. The price of crude oil dropped from a high of nearly $78 per barrel in July to roughly $61 per barrel by year-end -- the same level at which it started the year. Meanwhile, the price of natural gas declined roughly 46.5% in calendar year 2006. These factors, combined with softness in the housing market and signs of easing inflationary pressures, enabled the Fed to end its tightening campaign after 17 consecutive 25 basis point (.25%) increases in the target federal funds rate. What factors most influenced Portfolio performance? The Portfolio outperformed both its benchmark and its comparable Lipper category average for the year. The strong performance is attributed largely to successful stock selection in the information technology, industrials and health care sectors. Portfolio holdings in each of these sectors substantially outperformed those in the benchmark S&P MidCap 400 Index. In information technology, we saw outstanding performance from Anixter International, Inc., a provider of networking products, and Convergys Corp., a provider of business process outsourcing services. In the industrials sector, Allied Waste Industries, Inc., a collection, recycling and disposal services company, was a top performer. Strength in the health care sector was led by an investment in shares of Cephalon, Inc., a provider of biopharmaceutical products. The Portfolio also realized positive attribution from its investments in energy, with most of the outperformance relative to the benchmark coming from our positions in oil, gas and consumable fuels companies. The Portfolio's relative results were hindered by our positioning in the financial services sector, where several names detracted modestly from performance, particularly in the insurance industry. Most notably, Conseco, Inc., a provider of life insurance and supplemental medical insurance, declined as performance in the long-term care business deteriorated. The largest single detractor during the year was our position in Valassis Communications, Inc., a provider of marketing products and services that suffered from a troubled merger agreement with direct marketer ADVO, Inc. Other stocks that disappointed were software company Novell, Inc. and Smurfit-Stone Container Corp., a maker of paper-based packaging products. What changes were made to the Portfolio during the period? The Portfolio was positioned conservatively relative to its benchmark, and we used market weakness in the latter half of the year as an opportunity to become more aggressive in our positioning. We 69 took advantage of lower share prices in the information technology sector and moved from a slightly underweight position to an overweighting. We initiated positions in Citrix Systems, Inc., a provider of access infrastructure software and services, and Tellabs, Inc., a manufacturer and marketer of voice, data and video network access systems. We find that both firms offer compelling risk-adjusted returns based on our internal valuation parameters. Tellabs represented the Portfolio's largest position at period-end. Other changes within the information technology sector included the elimination of positions in McAfee, Inc., TIBCO Software, Inc. and Hyperion Solutions Corp. All three companies provided robust fundamental business outlooks on top of strong quarterly results, allowing us to trim our positions on stock strength. In industrials, we increased our position in certain defense electronics providers, while scaling back investments in engineering and construction companies. Goodrich Corp., a supplier of aerospace components and systems, is an example of an addition in the defense electronics area. Another important addition in industrials was The Timken Co., one of the Portfolio's top-10 holdings at period-end. Timken produces ball bearings and steel utilized by a variety of automotive and other industrial customers. We initiated the position based on Timken's strong cash flow and potential for current restructuring efforts to unlock additional value. We initiated new positions in the health care sector, including Biomet, Inc., a leader in the design and manufacture of joint replacements, and Endo Pharmaceuticals Holdings, Inc., a prescription drug company specializing in pain management. Endo has a leading market franchise in pain management products and was among the Portfolio's top-10 holdings at period-end. In consumer discretionary, we eliminated several positions as share prices reached our internal price targets. Among them were a number of off-price/ discount retailers, including Dollar Tree Stores, Inc. and TJX Cos., Inc., parent of the T.J. Maxx and Marshalls chains. Within the financial services sector, we trimmed exposure through the sale of TD Ameritrade Holdings Corp., a provider of online brokerage services, and TD Banknorth, Inc., a Northeast-based commercial banking provider, ending the period with an underweighting in the sector. On balance, most Portfolio changes during the period were stock-specific rather than driven by particular investment themes. One notable addition was OGE Energy Corp., a utility stock with a reasonable valuation and attractive dividend yield. We consider OGE Energy to be a company with solid management and a favorable rate base; as such, it has become the Portfolio's largest investment in the utilities sector. Deletions from the list of Portfolio holdings were driven in part by continued brisk merger-and-acquisition activity. For example, Cinergy Corp., a regulated utility, was acquired by Duke Energy Corp. Knight-Ridder, Inc. was acquired by McClatchy Co. to become the fourth-largest U.S. newspaper publisher. Maverick Tube Corp., a manufacturer of steel and tubular products, was the target of an acquisition by Tenaris SA., and Siebel Systems, Inc., a provider of customer-related management software, was acquired by Oracle Corp. Likewise, in November, Equity Office Properties Trust became the subject of a bidding war among private equity firms seeking to acquire the office and commercial property real estate investment trust. How would you characterize the Portfolio's position at the close of the period? Portfolio positioning is largely the result of where we are finding the most attractive investment opportunities. At December 31, 2006, the Portfolio was most overweight versus the S&P MidCap 400 Index in energy, followed by information technology and health care. The Portfolio was most underweight in utilities and consumer discretionary. The Portfolio's largest absolute exposure at year-end was in financial services, at 21.5% of net assets, followed by information technology at 16.5% and industrials at 14.4%. As we begin a new year, we acknowledge that the market is approaching a delicate juncture. The Fed hiked interest rates 17 times between June 2004 and June 2006, and the U.S. economy is showing some signs of slowing, with evidence most apparent in recent commentary out of the industrials and basic materials sectors. The critical question centers on how abruptly the economy will slow. The Fed interrupted its monetary tightening campaign at the August 8 meeting and remained on hold through year-end, allowing time for the economy to respond to its two-year tightening campaign. We believe that the economy will experience a soft landing, and have positioned the Portfolio accordingly. The Portfolio ended the year with a slight bias toward more defensive areas of the market. We believe this approach should help to drive favorable relative performance as economic growth continues to moderate, corporate earnings decelerate and investors grow increasingly selective. R.

BlackRock Mid Cap Value Opportunities Portfolio Disclosure of Expenses Shareholders of this 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, distribution fees including 12b-1 fees, and other Fund 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 the 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 the 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 During the Period* Account Value Account Value July 1, 2006 to July 1, 2006 December 31, 2006 December 31, 2006 ============================================================================================================= Actual ============================================================================================================= Class I $ 1,000 $1,078.60 $ 5.34 - ------------------------------------------------------------------------------------------------------------- Class II $ 1,000 $1,079.60 $ 5.39 - ------------------------------------------------------------------------------------------------------------- Class III $ 1,000 $1,078.60 $ 5.60 ============================================================================================================= Hypothetical (5% annual return before expenses)** ============================================================================================================= Class I $ 1,000 $1,019.76 $ 5.19 - ------------------------------------------------------------------------------------------------------------- Class II $ 1,000 $1,019.71 $ 5.24 - ------------------------------------------------------------------------------------------------------------- Class III $ 1,000 $1,019.51 $ 5.44 - ------------------------------------------------------------------------------------------------------------- * For each class of the Portfolio, expenses are equal to the annualized expense ratio for the class (1.03% for Class I, 1.04% for Class II and 1.08% for Class III), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). All outstanding shares of Class II and Class III were owned by an affiliated entity and did not accrue their distribution fees (12b-1 fees) for a portion of the period. If the distribution fees were accrued for the entire period, the actual expense ratios would have been approximately 1.18% and 1.28%, the actual expenses paid would have been approximately $6.12 and $6.63 and the hypothetical expenses paid would have been approximately $5.94 and $6.44 for Class II and Class III, respectively. ** 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. 73 BlackRock Series Fund, Inc.

See Notes to Financial Statements. 82 BlackRock Series Fund, Inc. BlackRock Mid Cap Value Opportunities Portfolio Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, FAM Series Fund, Inc. and Mercury Mid Cap Value Opportunities Portfolio were renamed BlackRock Series Fund, Inc. (the "Fund") and BlackRock Mid Cap Value Opportunities Fund (the "Portfolio"), respectively. The Fund is an open-end management investment company that is comprised of fourteen separate portfolios. This report relates to six of the Fund's Portfolios, all of which offer three classes of shares to the Merrill Lynch Life Insurance Company, ML Life Insurance Company of New York (indirect, wholly owned subsidiaries of Merrill Lynch & Co., Inc. ("Merrill Lynch")), and other insurance companies that are not affiliated with Merrill Lynch, for their separate accounts to fund benefits under certain variable annuity and variable life insurance contracts. The Portfolio is classified as "diversified," as defined in the Investment Company Act of 1940, as amended. Class I, Class II and Class III Shares have equal voting, dividend, liquidation and other rights, except that only shares of the respective classes are entitled to vote on matters concerning only that class. In addition, Class II and Class III Shares bear certain expenses related to the distribution of such shares. The Portfolio'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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Portfolio. (a) Valuation of investments -- Equity securities held by the 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 over-the-counter ("OTC") market, 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 market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Portfolio from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., believes that this method no longer produces fair valuations. 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. The Portfolio employs pricing services to provide certain securities prices for the Portfolio. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including valuations furnished by the pricing services retained by the Portfolio, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Portfolio under the general supervision of the Fund's Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. Generally, trading in foreign securities, 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 Portfolio's 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 83 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 Portfolio's 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 the Manager using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) Derivative financial instruments -- The Portfolio 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 the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Portfolio 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 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 Options -- The Portfolio may write and purchase call and put options. When the 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 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 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 Forward foreign exchange contracts -- The Portfolio 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. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets and liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Portfolio invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes -- It is the Portfolio'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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Dividends and distributions -- Dividends and distributions paid by the Portfolio are recorded on the ex-dividend dates. (g) Expenses -- Certain expenses have been allocated to the individual portfolios in the Fund on a 84 pro rata basis based upon the respective aggregate net asset value of each portfolio included in the Fund. (h) Securities lending -- The Portfolio 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 receives 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. (i) 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 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 the Portfolio's financial statements has not been determined. (j) Reclassification -- 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, during the current year, $156 has been reclassified between undistributed net investment income and undistributed net realized capital gains as a result of permanent differences attributable to foreign currency transactions. This reclassification has no effect on net assets or net asset values 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 Portfolio, approved a new Investment Advisory Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate 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 85 Portfolio. For such services, the Portfolio pays a monthly fee at the annual rate of .65% of the average daily value of the Portfolio's net assets. The Manager (and previously MLIM) has agreed to voluntarily waive its fees and reimburse for other Portfolio expenses so that the total annual portfolio operating expenses do not exceed 1.03%, exclusive of distribution fees. The Manager may discontinue or reduce this waiver at any time without notice. For the year ended December 31, 2006, MLIM and the Manager earned, waived and reimbursed fees as follows: - -------------------------------------------------------------------------------- MLIM The Manager ------------------------------------------- For the Period For the Period January 1, 2006 to September 30, 2006 September 29, 2006 to December 31, 2006 - -------------------------------------------------------------------------------- Fees earned .................... $ 31,787 $ 11,755 Waiver ......................... $(31,787) $ (6,040) Reimbursement .................. $ (764) -- - -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a monthly fee that is a percentage of the management fee paid by the Portfolio to the Manager. Pursuant to the Distribution Plans adopted by the Fund, in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Portfolio pays the Distributor an ongoing distribution fee each month at the annual rate of .15% and .25% of the average daily value of the Portfolio's Class II and Class III net assets, respectively. Class II and Class III commenced accruing the distribution fee on September 30, 2006. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund has also retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund and the Portfolio, invest cash collateral received by the Portfolio for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2006, the Portfolio reimbursed MLIM and the Manager $110 and $33, respectively, for certain accounting services. In addition, MLPF&S received $2,929 in commissions on the execution of portfolio security transactions for the year ended December 31, 2006. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or directors of the Fund were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2006 were $7,168,063 and $6,530,370, respectively. 4. Capital Share Transactions: Net increase in net assets derived from capital share transactions was $1,292,412 and $5,553,118 for the years ended December 31, 2006 and December 31, 2005, respectively. Transactions in capital shares for each class were as follows: - -------------------------------------------------------------------------------- Class I Shares for the Year Ended Dollar December 31, 2006 Shares Amount - -------------------------------------------------------------------------------- Shares sold .............................. 52,766 $ 608,241 Shares issued to shareholders in reinvestment of dividends and distributions ...................... 74,043 824,060 ------- ----------- Total issued ............................. 126,809 1,432,301 Shares redeemed ..........................

Short-Term Borrowings: The Fund, on behalf of the Portfolio, along with certain other funds managed by the Manager and its affiliates (or MLIM and its affiliates), is party to a $500,000,000 credit agreement with a group of lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms. The Portfolio pays a commitment fee of .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Portfolio's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended December 31, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2006 and December 31, 2005 was as follows: - -------------------------------------------------------------------------------- 12/31/2006 12/31/2005 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income .................................. $632,611 $240,518 Long-term capital gains .......................... 191,741 -- -------- -------- Total taxable distributions ........................ $824,352 $240,518 ======== ======== - -------------------------------------------------------------------------------- As of December 31, 2006, the components of accumulated earnings on a tax basis were as follows: - -------------------------------------------------------------------------------- Undistributed ordinary income--net .......................... $ 81,784 Undistributed long-term capital gains--net .................. 70,620 -------- Total undistributed earnings--net ........................... 152,404 Capital loss carryforward ................................... -- Unrealized gains--net ....................................... 315,517* -------- Total accumulated earnings--net ............................. $467,921 ======== - -------------------------------------------------------------------------------- * The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales. 7. Subsequent Event: On January 31, 2007, the Fund's Board of Directors has approved a Plan of Liquidation, Dissolution and Termination contingent upon contract holder approval of a Plan of Substitution. A preliminary proxy statement has been filed with the Securities and Exchange Commission and its review is pending. 87 BlackRock Series Fund, Inc. BlackRock Mid Cap Value Opportunities Portfolio Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock Series Fund, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of BlackRock Mid Cap Value Opportunities Portfolio of BlackRock Series Fund, Inc. (formerly Mercury Mid Cap Value Opportunities Portfolio of FAM Series Fund, Inc.) (the "Fund") as of December 31, 2006, and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two 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 audit 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. 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 BlackRock Mid Cap Value Opportunities Portfolio of BlackRock Series Fund, Inc. as of December 31, 2006, the results of its operations for the year then ended and the changes in its net assets and its financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BlackRock Short Term Bond Portfolio A Discussion With Your Portfolio Managers 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 Short Term Bond Portfolio's (formerly Mercury Low Duration Portfolio) Class I Shares had a total return of +4.75%. For the same period, the Portfolio's unmanaged benchmark, the Merrill Lynch U.S. 1-3 Year Corporate and Government Index, returned +4.25%. 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, 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. What factors most influenced the Portfolio's performance? The Portfolio provided favorable returns relative to its benchmark for the fiscal year. For the most part, performance benefited from our overweight exposure to high-quality, short-duration assets, including asset-backed securities (ABS), commercial mortgage-backed securities (CMBS), adjustable rate mortgages (ARMs) and collateralized mortgage obligations (CMOs). We maintained an overweight position in spread and credit sectors, focusing particularly on high-quality spread sectors. We felt that risk premia were likely to remain constant or decline in these sectors, and that helped them to perform quite well. Conversely, the Portfolio was underweight in the corporate and agency sectors, and this detracted from performance somewhat. Our short duration profile and our yield curve positioning, which benefited performance in the first half of the year as interest rates rose, hindered relative performance in the latter half of the year as rates declined. What changes were made to the Portfolio during the period? Despite price improvement in the Treasury market in the second half of the year, we continued to see greater relative value in spread sectors. Consistent with our somewhat defensive market posture, we maintained our emphasis on high-quality spread sectors and continued to favor structured assets, such as CMOs. In the last three months of the year, we modestly increased the Portfolio's exposure to the high yield asset class, as valuations in some non-investment-grade issues began to look attractive relative to BBB-rated issues. The Portfolio maintained a short duration relative to its benchmark throughout the 12-month period. How would you characterize the Portfolio's position at the close of the period? At December 31, 2006, the Portfolio continued to focus on positions in higher-quality issues within the corporate sector. We recently increased the Portfolio's exposure to fixed rate mortgages to capitalize on what appears to be stronger demand given these issues' higher yields. We also modestly increased exposure to floating-rate mortgages to capitalize on large money manager demand ahead of their inclusion in the Lehman Brothers Aggregate Bond Index in April. 89 The Portfolio ended the year with a short duration versus its 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. The Portfolio's duration at period-end was 1.45 years, compared to the index's duration of 1.68 years.

BlackRock Short Term Bond Portfolio Disclosure of Expenses Shareholders of this 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, distribution fees including 12b-1 fees, and other Fund 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 the 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 the 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.

All of the outstanding shares of Class II and Class III were owned by an affiliated entity and did not accrue their distribution fees (12b-1 fees) for a portion of the period. If the distribution fees were accrued for the entire period, the actual expense ratios would have been approximately .77% and .87%, the actual expenses paid would have been approximately $3.90 and $4.41, and the hypothetical expenses paid would have been approximately $3.88 and $4.38 for Class II and Class III, respectively. ** 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. 93 BlackRock Series Fund, Inc.

This report relates to six of the Fund's Portfolios, all of which offer three classes of shares to the Merrill Lynch Life Insurance Company, ML Life Insurance Company of New York (indirect, wholly owned subsidiaries of Merrill Lynch & Co., Inc. ("Merrill Lynch")), and other insurance companies that are not affiliated with Merrill Lynch, for their separate accounts to fund benefits under certain variable annuity and variable life insurance contracts. The Portfolio is classified as "diversified," as defined in the Investment Company Act of 1940, as amended. Class I, Class II and Class III Shares have equal voting, dividend, liquidation and other rights, except that only shares of the respective classes are entitled to vote on matters concerning only that class. In addition, Class II and Class III Shares bear certain expenses related to the distribution of such shares. The Portfolio'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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Portfolio. (a) Valuation of investments -- 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 Portfolio 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. In the case of options traded in the OTC market, valuation is the last asked price (options written) or the last bid price (options purchased). Swap agreements 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. 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. Equity securities held by the 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 market, 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 market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market 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 Portfolio's 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 Portfolio's net asset value. If events (for example, a company 102 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) Derivative financial instruments -- The Portfolio 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 the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Portfolio 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 financial 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 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 Options -- The Portfolio may write and purchase call and put options. When the 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 gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets and 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 Portfolio invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes -- It is the Portfolio'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. (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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. The Portfolio amortizes all premiums and discounts on debt securities. (f) Dividends and distributions -- Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (g) Expenses -- Certain expenses have been allocated to the individual portfolios in the Fund on a pro rata basis based upon the respective aggregate net asset value of each portfolio included in the Fund. (h) Securities lending -- The Portfolio 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 receives 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 103 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. (i) 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 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 the Portfolio's financial statements has not been determined. (j) Reclassification -- 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, during the current year, $2,285 has been reclassified between accumulated net realized capital losses and undistributed net investment income as a result of permanent differences attributable to swap agreements and accounting for paydowns. This reclassification has no effect on net assets or net asset values 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 Portfolio, approved a new Investment Advisory Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Portfolio has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate 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 Portfolio. For such services, the Portfolio pays a monthly fee at the annual rate of .46% of the average daily value of the Portfolio's net assets. The Manager (and previously MLIM) has agreed to voluntarily waive its fees and reimburse for other Portfolio expenses so that the total annual portfolio operating expenses do not exceed .66%, exclusive of distribution fees. The Manager may discontinue or reduce this waiver at any time without notice. For the year ended December 31, 2006, MLIM and the Manager earned, waived and reimbursed fees as follows: - -------------------------------------------------------------------------------- MLIM The Manager ----------------------------------------- For the Period For the Period January 1, 2006 to September 30, 2006 September 29, 2006 to December 31, 2006 - -------------------------------------------------------------------------------- Fees earned ...................... $ 96,004 $ 2,685 Waiver ........................... $(56,237) $ (2,685) Reimbursement .................... -- $(47,589) - -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a monthly fee that is 104 a percentage of the management fee paid by the Portfolio to the Manager. Pursuant to the Distribution Plans adopted by the Fund, in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Portfolio pays the Distributor an ongoing distribution fee each month at the annual rate of .15% and .25% of the average daily value of the Portfolio's Class II and Class III net assets, respectively. Class II and Class III commenced accruing the distribution fee on September 30, 2006. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund also has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund and the Portfolio, invest cash collateral received by the Portfolio for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2006, the Portfolio reimbursed MLIM and the Manager $499 and $6, respectively, for certain accounting services. In addition, MLPF&S received $101 in commissions on the execution of portfolio security transactions for year ended December 31, 2006. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or directors of the Company were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or directors of the Company are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales (including paydowns) of investments, excluding short-term securities, for the year ended December 31, 2006 were $23,736,854 and $38,755,275, respectively.

Short-Term Borrowings: The Fund, on behalf of the Portfolio, along with certain other funds managed by the Manager and its affiliates (or MLIM and its affiliates), is party to a $500,000,000 credit agreement with a group of lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms. The Portfolio pays a commitment fee of .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Portfolio's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended December 31, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2006 and December 31, 2005 was as follows: - -------------------------------------------------------------------------------- 12/31/2006 12/31/2005 - -------------------------------------------------------------------------------- Distributions paid from: Ordinary income .......................... $854,378 $528,254 -------- -------- Total taxable distributions ................ $854,378 $528,254 ======== ======== - -------------------------------------------------------------------------------- As of December 31, 2006, the components of accumulated losses on a tax basis were as follows: - ----------------------------------------------------------------------------- Undistributed ordinary income--net ........................ $ 8,614 Undistributed long-term capital gains--net ................ -- --------- Total undistributed earnings--net ......................... 8,614 Capital loss carryforward ................................. (279,425)* Unrealized losses--net .................................... (3,390)** --------- Total accumulated losses--net ............................. $(274,201) ========= - ----------------------------------------------------------------------------- * On December 31, 2006, the Portfolio had a net capital loss carryforward of $279,425, of which $93,783 expires in 2013 and $185,642 expires in 2014. This amount will be available to offset like amounts of any future taxable gains. ** The difference between book-basis and tax-basis net unrealized losses is attributable primarily to the realization for tax purposes of unrealized gains (losses) on financial futures contracts and the deferral of post-October capital losses for tax purposes. 7. Subsequent Event: On January 31, 2007, the Fund's Board of Directors has approved a Plan of Liquidation, Dissolution and Termination contingent upon contract holder approval of a Plan of Substitution. A preliminary proxy statement has been filed with the Securities and Exchange Commission and its review is pending. 106 BlackRock Series Fund, Inc. BlackRock Short Term Bond Portfolio Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of BlackRock Series Fund, Inc.: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of BlackRock Short Term Bond Portfolio of BlackRock Series Fund, Inc. (formerly Mercury Low Duration Portfolio of FAM Series Fund, Inc.) (the "Fund") as of December 31, 2006 and the related statement of operations for the year then ended and the statements of changes in net assets and the financial highlights for each of the two 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 audit 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. 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 BlackRock Short Term Bond Portfolio of BlackRock Series Fund, Inc. as of December 31, 2006, the results of its operations for the year then ended and the changes in its net assets and its financial highlights for each of the two years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

BlackRock Small Cap Index Portfolio A Discussion With Your Portfolio Managers 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 Small Cap Index Portfolio's (formerly Mercury Small Cap Index Portfolio) Class I Shares generated a total return of +17.62%. For the same period, the benchmark Russell 2000 Index advanced +18.37%. The Russell 2000 Index is a market-weighted index composed of approximately 2,000 common stocks issued by small-capitalization U.S. companies in a range of businesses. As the value of the Russell 2000 fluctuated during the past 12 months, the Portfolio's performance generally tracked that of the Index. Following decent, but uninspiring, results in 2004 and 2005, U.S. equities surged forward in 2006, with the S&P 500 Index advancing 15.79% to close at 1,418. Small-cap stocks posted even stronger gains, thanks to exceptionally strong performance in the first few months of the year. Key highlights of the 12-month period included weaker economic growth triggered by a slowdown in the U.S. housing market; a long-awaited pause in the Federal Reserve Board's (the Fed) interest rate hiking campaign; threats of higher inflation; and robust corporate earnings, which rose by double-digit percentages for an unprecedented fifth consecutive year. Amid these crosscurrents, financial markets were left to weather a high degree of volatility. At the outset, a burgeoning corporate sector, ample liquidity and record levels of merger-and-acquisition (M&A) activity provided a solid backdrop for equity markets. During the first few months of 2006, U.S. stocks were solidly on an upward trajectory, posting the best first quarter gains in several years. Of note, the S&P 500 Index advanced 4.21% in the quarter, marking its largest gain since the fourth quarter of 2004 (+9.23%) and its best first quarter since 1999 (+4.98%). Growth continued outside of the housing and auto sectors (capital spending in particular expanded at a brisk pace); private equity deals, M&A action and corporate buy-backs abounded in high volumes; and corporate cash flows held steady. Notwithstanding such broad-based strength, evidence of an economic slowdown mounted. By May, we saw a striking shift in investor sentiment, triggered by a deceleration in consumer spending, rising energy prices, a slump in housing activity and uncertainty around Fed policy and the sustainability of economic growth. Stock market volatility took on a more negative spin and eventually resulted in the first double-digit correction for U.S. equity markets in nearly four years. The average U.S. stock fell by about 12% and stocks outside the U.S. were hit even harder. The pullback could be attributed to several factors, not the least of which was that the lagged effects of higher interest rates and oil prices finally took their toll on both the economy and stock prices. Further, a resurgence of inflation fears prompted the Fed to continue its interest rate tightening campaign. Under the auspices of new Chairman Ben Bernanke, the central bank ended the second quarter with its 17th consecutive 25 basis point (.25%) interest rate hike since June 2004, bringing the target federal funds rate to 5.25%. As the second half of 2006 got underway, positive momentum returned to the market. The Fed made big news in August by finally ending its streak of rate increases. At the same time, commodity prices collapsed. After reaching an all-time high near $78 per barrel in July, crude oil ended the year at $61 per barrel. Stocks generally climbed back above the levels they reached prior to the market's earlier retrenchment. Most equity markets experienced one of their best third-quarter periods in several years, though there was a broad-based changing of the guard that favored larger-cap, higher-quality and more predictable stocks over small-cap, lower-quality and more cyclical securities (as was the trend early in the year). Macroeconomic uncertainty persisted in the third quarter. Investors struggled with moderating economic activity -- real gross domestic product (GDP) growth was estimated at 2%, compared to 2.6% in the second quarter and 5.6% in the first quarter. The magnitude of the housing downturn and its effect on the consumer sector was a significant wildcard. Weakness in the U.S. dollar was challenging the stability of currency markets. Moreover, tensions in the Middle East were heating up, and economic data offered a mixed outlook for inflation. Still, strong momentum continued in the equity markets during the year's final quarter. Key to investors' optimism were: a strong labor market, where the unemployment rate reached a post-9/11 low and year-on-year average hourly salaries reached a post-9/11 high; receding risks of higher inflation and high oil prices; and finally, the pervasive strength in corporate fundamentals that included reasonably good investment levels, healthy balance sheets and profit margins. 108 2006 ended and the new year began with the world awash in liquidity, global economic growth still quite strong despite the U.S. slowdown, record-high corporate profitability, fairly low inflation and interest rates, and relatively strong investor confidence. For the 12-month period, small-cap stocks, as measured by the Russell 2000 Index, outpaced the +15.26% return of the Russell Midcap Index and the +15.46% return of the large-cap Russell 1000 Index. Within the Russell 2000, the value style of investing significantly outperformed the growth style for the period, with the Russell 2000 Value Index returning +23.48% versus the +13.35% return of the Russell 2000 Growth Index. What changes were made to the Portfolio during the period? Throughout the period, as changes were made to the composition of the Russell 2000 Index, the Portfolio purchased and sold securities to maintain its objective of replicating the risks and return of the benchmark. On June 30, 2006, the Russell 2000 Index underwent its annual reconstitution. To maintain the Portfolio's tight tracking to the benchmark, we adjusted it to be in line with the new benchmark as of the rebalancing's effective date. How would you characterize the Portfolio's position at the close of the period? Heading into 2007, we believe continued moderation in economic growth will put pressure on corporate earnings, which have been on a record run with five consecutive years of double-digit growth. Solid corporate fundamentals and balance sheet strength, alongside strong non-U.S. economic growth, should help corporate profits remain positive, but the rate of gain will likely slow noticeably as record-high profit margins will be difficult to sustain. Against this backdrop, the Portfolio remains positioned to match the risk characteristics of its benchmark, whatever direction the market takes. Debra L.

BlackRock Small Cap Index Portfolio Disclosure of Expenses Shareholders of this 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, distribution fees including 12b-1 fees, and other Fund 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 the 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 the 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 During the Period* Account Value Account Value July 1, 2006 to July 1, 2006 December 31, 2006 December 31, 2006 =================================================================================================================== Actual =================================================================================================================== Class I $ 1,000 $1,090.40 $ 2.87 - ------------------------------------------------------------------------------------------------------------------- Class II $ 1,000 $1,089.50 $ 3.49 - ------------------------------------------------------------------------------------------------------------------- Class III $ 1,000 $1,088.60 $ 3.75 =================================================================================================================== Hypothetical (5% annual return before expenses)** =================================================================================================================== Class I $ 1,000 $1,022.16 $ 2.77 - ------------------------------------------------------------------------------------------------------------------- Class II $ 1,000 $1,021.56 $ 3.38 - ------------------------------------------------------------------------------------------------------------------- Class III $ 1,000 $1,021.31 $ 3.63 - ------------------------------------------------------------------------------------------------------------------- * For each class of the Portfolio, expenses are equal to the annualized expense ratio for the class (.55% for Class I, .67% for Class II and .72% for Class III), multiplied by the average account value over the period, multiplied by 182/365 (to reflect the one-half year period shown). All of the outstanding shares of Class II and Class III were owned by an affiliated entity and did not accrue their distribution fees (12b-1 fees) for a portion of the period. If the distribution fees were accrued for the entire period, the actual expense ratios would have been approximately .70% and .80%, the actual expenses paid would have been approximately $3.65 and $4.17, and the hypothetical expenses paid would have been approximately $3.53 and $4.03 for Class II and Class III, respectively. ** 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. 112 BlackRock Series Fund, Inc.

See Notes to Financial Statements. 124 BlackRock Series Fund, Inc. BlackRock Small Cap Index Portfolio Notes to Financial Statements 1. Significant Accounting Policies: On September 29, 2006, FAM Series Fund, Inc. and Mercury Small Cap Index Portfolio were renamed BlackRock Series Fund, Inc. (the "Fund") and BlackRock Small Cap Index Portfolio (the "Portfolio"), respectively. The Fund is an open-end management investment company that is comprised of fourteen separate portfolios. This report relates to six of the Fund's Portfolios, all of which offer three classes of shares to the Merrill Lynch Life Insurance Company, ML Life Insurance Company of New York (indirect, wholly owned subsidiaries of Merrill Lynch & Co., Inc. ("Merrill Lynch")), and other insurance companies not affiliated with Merrill Lynch, for their separate accounts to fund benefits under certain variable annuity and variable life insurance contracts. The Portfolio is classified as "non-diversified," as defined in the Investment Company Act of 1940, as amended. Class I, Class II and Class III Shares have equal voting, dividend, liquidation and other rights, except that only shares of the respective classes are entitled to vote on matters concerning only that class. In addition, Class II and Class III Shares bear certain expenses related to the distribution of such shares. The Portfolio'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. Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Portfolio. (a) Valuation of investments -- Equity securities held by the 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 over-the-counter ("OTC") market, 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 market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Portfolio from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., believes that this method no longer produces fair valuations. 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. The Portfolio employs pricing services to provide certain securities prices for the Portfolio. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including valuations furnished by the pricing services retained by the Portfolio, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Portfolio under the general supervision of the Fund's Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. 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 Portfolio's 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 125 the close of business on the NYSE that may not be reflected in the computation of the Portfolio's 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 the Manager using a pricing service and/or procedures approved by the Fund's Board of Directors. (b) Derivative financial instruments -- The Portfolio 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 the securities markets. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts -- The Portfolio 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 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 Options -- The Portfolio may write and purchase call and put options. When the 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 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 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 Forward foreign exchange contracts -- The Portfolio 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. (c) Foreign currency transactions -- Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets and liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Portfolio invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes -- It is the Portfolio'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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Dividends and distributions -- Dividends and distributions paid by the Portfolio are recorded on the ex-dividend dates. (g) Expenses -- Certain expenses have been allocated to the individual portfolios in the Fund on a 126 pro rata basis based upon the respective aggregate net asset value of each portfolio included in the Fund (h) Securities lending -- The Portfolio 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 receives 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. (i) 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 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 the Portfolio's financial statements has not been determined. (j) Reclassification -- 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, during the current year, $310 has been reclassified between undistributed net investment income and paid-in capital in excess of par as a result of permanent difference attributable to non-deductible expenses. This reclassification has no effect on net assets or net asset values 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 Portfolio, approved a new Investment Advisory Agreement with the Manager. BlackRock Advisors, Inc. was recently reorganized into a limited liability company and renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's Manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate 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 Portfolio. 127 For such services, the Portfolio pays a monthly fee at the annual rate of .30% of the average daily value of the Portfolio's net assets. The Manager (and previously MLIM) has agreed to voluntarily waive its fees and reimburse for other Portfolio expenses so that the total annual portfolio operating expenses do not exceed .55%, exclusive of distribution fees. The Manager may discontinue or reduce this waiver at any time without notice. For the year ended December 31, 2006, MLIM and the Manager earned, waived and reimbursed fees as follows: - -------------------------------------------------------------------------------- MLIM The Manager -------------------------------------------- For the Period For the Period January 1, 2006 to September 30, 2006 September 29, 2006 to December 31, 2006 Fees earned ...................... $ 20,311 $ 6,321 Waiver ........................... $(20,311) $ (6,321) Reimbursement .................... $ (8,869) $ (8,060) - -------------------------------------------------------------------------------- In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays the Sub-Adviser for services it provides a monthly fee that is a percentage of the management fee paid by the Portfolio to the Manager. Pursuant to the Distribution Plans adopted by the Fund, in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Portfolio pays the Distributor an ongoing distribution fee each month at the annual rate of .15% and .25% of the average daily value of the Portfolio's Class II and Class III net assets, respectively. Class II and Class III commenced accruing the distribution fee on September 30, 2006. The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Fund has also retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund and the Portfolio, invest cash collateral received by the Portfolio for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2006, BIM received $280 in securities lending agent fees. For the year ended December 31, 2006, the Portfolio reimbursed MLIM and the Manager $153 and $45, respectively, for certain accounting services. In addition, MLPF&S earned $354 in commissions on the execution of portfolio security transactions for the year ended December 31, 2006. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or directors of the Fund were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or directors of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2006 were $1,395,601 and $2,042,252, respectively. 4. Capital Share Transactions: Net increase (decrease) in net assets derived from capital share transactions was ($500,612) and $8,119,162 for the years ended December 31, 2006 and December 31, 2005, respectively. Transactions in capital shares for each class were as follows: - ------------------------------------------------------------------------------- Class I Shares for the Year Ended Dollar December 31, 2006 Shares Amount - ------------------------------------------------------------------------------- Shares sold .............................. 31,520 $ 355,961 Shares issued to shareholders in reinvestment of dividends and distributions ...................... 57,229 655,837 ----------- ----------- Total issued ............................. 88,749 1,011,798 Shares redeemed ..........................

Short-Term Borrowings: The Fund, on behalf of the Portfolio, along with certain other funds managed by the Manager and its affiliates (or MLIM and its affiliates), is party to a $500,000,000 credit agreement with a group of lenders. The Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Portfolio may borrow up to the maximum amount allowable under the Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms. The Portfolio pays a commitment fee of .06% per annum based on the Portfolio's pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Portfolio's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Portfolio did not borrow under the credit agreement during the year ended December 31, 2006. 6. Distributions to Shareholders: The tax character of distributions paid during the fiscal years ended December 31, 2006 and December 31, 2005 was as follows: - ------------------------------------------------------------------------------- 12/31/2006 12/31/2005 - ------------------------------------------------------------------------------- Distributions paid from: Ordinary income ........................ $ 150,143 $ 122,713 Long-term capital gains ................ 505,882 2,822 ----------- ----------- Total taxable distributions .............. $ 656,025 $ 125,535 =========== =========== - ------------------------------------------------------------------------------- As of December 31, 2006, the components of accumulated earnings on a tax basis were as follows: - ------------------------------------------------------------------------------- Undistributed ordinary income--net ......................... $ 3,882 Undistributed long-term capital gains--net ................. 50,895 ---------- Total undistributed earnings--net .......................... 54,777 Capital loss carryforward .................................. -- Unrealized gains--net ...................................... 985,449* ---------- Total accumulated earnings--net ............................ $1,040,226 ========== - ------------------------------------------------------------------------------- * The difference between book-basis and tax-basis net unrealized gains is attributable primarily to the tax deferral of losses on wash sales, the realization for tax purposes of unrealized gains/losses on certain financial futures contracts and other book/tax differences. 7. Subsequent Event: On January 31, 2007, the Fund's Board of Directors has approved a Plan of Liquidation, Dissolution and Termination contingent upon contract holder approval of a Plan of Substitution. A preliminary proxy statement has been filed with the Securities and Exchange Commission and its review is pending. 129 BlackRock Series Fund, Inc.

Disclosure of Investment Advisory Agreement 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" below. The term "Investment Adviser" as used herein refers to Merrill Lynch Investment Managers, L.P. New BlackRock Investment Advisory Agreement -- Matters Considered by the Board In connection with the Transaction between Merrill Lynch and BlackRock, the Fund's Board of Directors considered a new investment advisory agreement (the "New Investment Advisory Agreement") between the Fund, on behalf of the Portfolios, and BlackRock Advisors, Inc. ("BlackRock Advisors"). If the New Investment Advisory Agreement is approved by shareholders, it will become effective upon the closing of the Transaction, which is expected in the third quarter of 2006. The Board discussed the New Investment Advisory Agreement at telephonic and in-person meetings held during April and May 2006. The Board, including the independent directors, approved the New Investment Advisory Agreement on May 8, 2006. To assist the Board in its consideration of the New Investment Advisory Agreement, BlackRock provided materials and information about BlackRock, including its financial condition and asset management capabilities and organization, and Merrill Lynch provided materials and information about the Transaction. The independent directors, through their independent legal counsel, also requested and received additional information from Merrill Lynch and BlackRock in connection with their consideration of the New Investment Advisory Agreement. The additional information was provided in advance of the May 2006 meeting. In addition, the independent directors consulted with their counsel and Fund counsel on numerous occasions, discussing, among other things, the legal standards and certain other considerations relevant to the directors' deliberations. At the Board meetings, the directors discussed with Merrill Lynch management and certain BlackRock representatives the Transaction, its strategic rationale and BlackRock's general plans and intentions regarding the Portfolios. At these Board meetings, representatives of Merrill Lynch and BlackRock made presentations to and responded to questions from the Board. The directors also inquired about the plans for and anticipated roles and responsibilities of certain employees and officers of the Investment Adviser and certain affiliates being transferred to BlackRock in connection with the Transaction. The independent directors of the Board also conferred separately and with their counsel about the Transaction and other matters related to the Transaction on a number of occasions, including in connection with the April and May 2006 meetings. After the presentations and after reviewing the written materials provided, the independent directors met in executive sessions with their counsel to consider the New Investment Advisory Agreement. In connection with the Board's review of the New Investment Advisory Agreement, Merrill Lynch and/or BlackRock advised the directors about a variety of matters. The advice included the following, among other matters: o that there is not expected to be any diminution in the nature, quality and extent of services provided to any Portfolio and its shareholders by BlackRock Advisors, including compliance services; o that operation of New BlackRock as an independent investment management firm will enhance its ability to attract and retain talented professionals; o that each Portfolio should benefit from having access to BlackRock's state of the art technology and risk management analytic tools, including investment tools, provided under the BlackRock Solutions(R) brand name; o that BlackRock has no present intention to alter any applicable expense waivers or reimbursements currently in effect and, while it reserves the right to do so in the future, it would seek the approval of the Board before making any changes; o that in connection with the Transaction, Merrill Lynch and BlackRock have agreed to conduct, and use reasonable best efforts to cause their respective affiliates to conduct, their respective businesses in compliance with the conditions of Section 15(f) of the Investment Company Act of 1940 (the "1940 Act") in relation to any public funds 131 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. 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 132 statistics, and direct and indirect benefits to the Investment Adviser and its affiliates from their relationship with the Portfolio. In their deliberations, the directors considered information received in connection with their most recent continuation of the Current Investment Advisory Agreement, in addition to information provided by BlackRock and BlackRock Advisors in connection with their evaluation of the terms and conditions of the New Investment Advisory Agreement. The directors did not identify any particular information that was all-important or controlling, and each director attributed different weights to the various factors. The directors' determinations were made separately in respect of each Portfolio. The directors, including a majority of the independent directors, concluded that the terms of the New Investment Advisory Agreement are appropriate, that the fees to be paid are reasonable in light of the services to be provided to the Portfolio, and that the New Investment Advisory Agreement should be approved and recommended to each Portfolio's shareholders. Nature, Quality and Extent of Services Provided -- The Board reviewed the nature, extent and quality of services provided by the Investment Adviser, including the investment advisory services and the resulting performance of each Portfolio, as well as the nature, quality and extent of services expected to be provided by BlackRock Advisors. The Board focused primarily on the Investment Adviser's investment advisory services and each Portfolio's investment performance, but also considered certain areas in which both the Investment Adviser and the Portfolio receive services as part of the Merrill Lynch complex. The Board compared each Portfolio's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of mutual funds, and the performance of a relevant index or combination of indexes. While the Board reviews performance data at least quarterly, consistent with the Investment Adviser's investment goals, the Board attaches more importance to performance over relatively long periods of time, typically three to five years. In evaluating the nature, quality and extent of the services to be provided by BlackRock Advisors under the New Investment Advisory Agreement, the directors considered, among other things, the expected impact of the Transaction on the operations, facilities, organization and personnel of BlackRock Advisors and how it would affect each Portfolio; the ability of BlackRock Advisors to perform its duties after the Transaction; and any anticipated changes to the current investment and other practices of each Portfolio. The directors considered BlackRock's advice as to proposed changes in portfolio management personnel of certain Portfolios after the closing of the Transaction. The directors were given information with respect to the potential benefits to each Portfolio and its shareholders from having access to BlackRock's state of the art technology and risk management analytic tools, including the investment tools provided under the BlackRock Solutions brand name. The directors were advised that, as a result of Merrill Lynch's equity interest in BlackRock after the Transaction, each Portfolio will continue to be subject to restrictions concerning certain transactions involving Merrill Lynch affiliates (for example, transactions with a Merrill Lynch broker-dealer acting as principal) absent revised or new regulatory relief. The directors were advised that a revision of existing regulatory relief with respect to these restrictions was being sought from the Securities and Exchange Commission and were advised of the possibility of receipt of such revised regulatory relief. There can be no assurance that such relief will be obtained. Based on their review of the materials provided and the assurances they had received from the management of Merrill Lynch and of BlackRock, the directors determined that the nature and quality of services to be provided to each Portfolio under the New Investment Advisory Agreement were expected to be as good or better than that provided under the Current Investment Advisory Agreement. It was noted, however, that it is expected that there will be changes in personnel following the Transaction and the combination of the operations of the Investment Adviser and its affiliates with those of BlackRock. The directors noted that if current portfolio managers or other personnel cease to be available, the Board would consider all available options, which could include seeking the investment advisory or other services of BlackRock affiliates. Accordingly, the directors concluded that, overall, they were satisfied at the present time with assurances from BlackRock and BlackRock Advisors as to the expected nature, extent and quality of the services to be provided to each Portfolio under the New Investment Advisory Agreement. Costs of Services Provided and Profitability -- It was noted that, in conjunction with the recent review of the Current Investment Advisory 133 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 Global SmallCap, Mercury Mid Cap Value Opportunities and Mercury International Index Portfolios, the Board considered the services to be provided by and the fees to be charged by BlackRock Advisors to other funds with similar investment mandates and noted that the fees charged by BlackRock Advisors in those cases, including fee waivers and expense reimbursements, were generally comparable to those being charged to the Portfolio. The Board concluded that the each Portfolio's management fee and fee rate and overall expense ratio are reasonable compared to those of other comparable funds. In evaluating the costs of the services to be provided by BlackRock Advisors under the New Investment Advisory Agreement, the directors considered, among other things, whether advisory fees or other expenses would change as a result of the Transaction. Based on their review of the materials provided and the fact that the New Investment Advisory Agreement is substantially similar to the Current Investment Advisory Agreement in all material respects, including the rate of compensation, the directors determined that the Transaction should not increase the total fees payable, including any fee waivers and expense reimbursements, for advisory and administrative services. The directors noted that it was not possible to predict with certainty New BlackRock's future profitability from its relationship with each Portfolio. The directors discussed with BlackRock Advisors its general methodology to be used in determining New BlackRock's profitability with respect to its relationship with each Portfolio. The directors noted that they expect to receive profitability information from New BlackRock on at least an annual basis and thus be in a position to evaluate whether any adjustments in a Portfolio's fees and/or fee breakpoints would be appropriate. Fees and Economies of Scale -- The Board considered the extent to which economies of scale might be realized as the assets of each Portfolio increase and whether there should be changes in the management fee rate or structure in order to enable the Portfolio to participate in these economies of scale. The Board determined that changes were not currently necessary and that each Portfolio appropriately participated in these economies of scale. In reviewing the Transaction, the directors considered, among other things, whether advisory fees or other expenses would change as a result of the Transaction. Based on the fact that the New Investment Advisory Agreement is substantially similar to the Current Investment Advisory Agreement in all material respects, including the rate of compensation, the directors determined that as a result of the Transaction, no Portfolio's total advisory fees would be higher than the fees under its Current Investment Advisory Agreement. The directors noted that in conjunction with their most recent deliberations concerning the Current Investment Advisory Agreement, the directors had determined that the total fees for advisory and administrative services for each Portfolio were reasonable in light of the services provided. It was noted that in conjunction with the recent review of the Current Investment Advisory Agreement, the directors had received, among other things, a report from Lipper comparing each Portfolio's fees, expenses and performance to those of a peer group selected by Lipper, and information as to the fees charged by the Investment Adviser to other registered investment company clients for investment management services. The directors concluded that, because the rates for advisory fees for each Portfolio would be no higher than its current fee rates, the proposed management fee structure, including any fee waivers, was reasonable and that no additional changes were currently necessary. Fall-Out Benefits -- In evaluating the fall-out benefits to be received by BlackRock Advisors under the New Investment Advisory Agreement, the directors considered whether the Transaction would have an impact on the fall-out benefits received by the Investment Adviser by virtue of the Current Investment Advisory Agreement. Based on their review of the materials provided, including materials received in connection with their most recent continuance of the Current Investment Advisory Agreement, and their discussions with management of the Investment Adviser and BlackRock, the directors determined that those benefits could include increased ability for BlackRock to distribute 134 shares of its funds and other investment products and, where applicable, to obtain research services using portfolio transaction brokerage commissions. The directors also considered possible benefits stemming from the proposal that PFPC Financial Services, an affiliate of BlackRock, serve as transfer agent for each Portfolio following the Transaction. The directors noted that any benefits were difficult to quantify with certainty at this time, and indicated that they would continue to evaluate them going forward. Investment Performance -- The directors considered investment performance for each Portfolio. The directors compared each Portfolio's performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of mutual funds, and the performance of a relevant index or combination of indexes. The comparative information received from Lipper showed each Portfolio's performance at various levels within the range of performance of comparable funds over different time periods. While the Board reviews performance data at least quarterly, consistent with the Investment Adviser's investment goals, the Board attaches more importance over relatively long periods of time, typically three to five years. The directors believed each Portfolio's performance was satisfactory. Also, the directors took into account the investment performance of funds currently advised by BlackRock Advisors. The Board considered comparative information from Lipper which showed that the performance of the funds advised by BlackRock Advisors was within the range of performance of comparable funds over different time periods. The Board noted BlackRock's considerable investment management experience and capabilities, but was unable to predict what effect, if any, consummation of the Transaction would have on the future performance of any Portfolio. Conclusion -- After the independent directors of the Fund deliberated in executive session, the entire Board, including the independent directors, approved the New Investment Advisory Agreement on behalf of each Portfolio, concluding that the Portfolio's advisory fee rate was reasonable in relation to the services provided and that the New Investment Advisory Agreement was in the best interests of the shareholders. In approving the New Investment Advisory Agreement, the Board noted that it anticipated reviewing the continuance of the agreement in advance of the expiration of the initial two-year period. Contingent BlackRock Sub-Advisory Agreement -- Matters Considered by the Board At the telephonic and in-person meetings held during April and May 2006 at which the Board discussed and approved the New Investment Advisory Agreement, the Board of Directors, including the independent directors, also discussed and approved a contingent sub-advisory agreement (the "Contingent Sub-Advisory Agreement") between the Investment Adviser and BlackRock Advisors (the "BlackRock Sub-Adviser"). The Contingent Sub-Advisory Agreement is intended to ensure that a Portfolio operate with efficient portfolio management services until the closing of the Transaction, in the event that the Board deems it necessary and in the best interests of the Portfolio and its shareholders that the BlackRock Sub-Adviser assist in managing the operations of the Portfolio during the interim period until the closing of the Transaction. If shareholders approve the Contingent Sub-Advisory Agreement, it will take effect only upon recommendation from the Investment Adviser and upon subsequent approval of the Board in the period up to the closing of the Transaction. The effectiveness of the Contingent Sub-Advisory Agreement, therefore, would be contingent on further Board approval after shareholders approve it. Pursuant to each Contingent Sub-Advisory Agreement, the BlackRock Sub-Adviser would receive a monthly fee from the Investment Adviser equal to 50% of the advisory fee received by the Investment Adviser. The Investment Adviser would pay the BlackRock Sub-Adviser out of its own resources. There would be no increase in any Portfolio's expenses as a result of the Contingent Sub-Advisory Agreement. In making its approval at the May in-person meeting, the Board considered the Contingent Sub-Advisory Agreement in conjunction with the New Investment Advisory Agreement and reviewed the same information and factors discussed above. The Board also considered in conjunction with the Contingent Sub-Advisory Agreement the necessity of ensuring that each Portfolio operates with effective management services until the closing of the Transaction. In reviewing the sub-advisory fee rate provided in the Contingent Sub-Advisory Agreement, the Board took note of the fact that both the Investment Adviser and the BlackRock Sub-Adviser would have significant responsibilities under their respective advisory agreements. The Investment Adviser would remain responsible for oversight of a Portfolio's operations and administration and the BlackRock Sub-Adviser would provide advisory services to the Portfolio 135 under the Contingent Sub-Advisory Agreement. The Board also took into account the expected short duration of the term of any Contingent Sub-Advisory Agreement and the fact that no Portfolio's advisory fees would increase as a result of the Contingent Sub-Advisory Agreement. Under all of the circumstances, the Board concluded that it was a reasonable allocation of fees for the BlackRock Sub-Adviser to receive 50% of the advisory fee paid by each Portfolio to the Investment Adviser. After the independent directors deliberated in executive session, the entire Board, including the independent directors, approved the Contingent Sub-Advisory Agreement, concluding that the advisory fee for each Portfolio was reasonable in relation to the services provided and that the Contingent Sub-Advisory Agreement was in the best interests of shareholders. BlackRock Series Fund, Inc. Disclosure of Sub-Advisory Agreement 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 Equity Dividend Portfolio, Global SmallCap Portfolio, International Index Portfolio, Mid Cap Value Opportunities Portfolio and Small Cap Index 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 these Portfolios. o BlackRock Financial Management, Inc. ("BFM"), with respect to Short-Term Bond 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 Short-Term Bond Portfolio. The BlackRock Sub-Advisory Agreements became effective on September 29, 2006, at the same time the New Investment Advisory Agreement with BlackRock Advisors (which had been approved by the Portfolios' shareholders) became effective. BlackRock Advisors pays the Sub-Advisers out of its own resources, and there is no increase in the expenses of any Portfolio as a result of the BlackRock Sub-Advisory Agreements. In approving the BlackRock Sub-Advisory Agreements at the August 2006 in-person meeting, the Board reviewed its considerations in connection with its approval of the New Investment Advisory Agreement in May 2006. The Board relied on the same information and considered the same factors as those discussed above in connection with the approval of the New Investment Advisory Agreement. In reviewing the sub-advisory fee rates provided for in the BlackRock Sub-Advisory Agreements, the Board noted the fact that both BlackRock Advisors and each Sub-Adviser have significant responsibilities under their respective advisory agreements. Under the New Investment Advisory Agreement, BlackRock Advisors remains responsible for the overall management of each Portfolio and for oversight of each Portfolio's operations and administration. Under the BlackRock Sub-Advisory Agreements, each Sub-Adviser provides advisory services to each pertinent Portfolio and is responsible for the day-to-day management of the Portfolio's portfolio. The Board also took into account the fact that there is no increase in total advisory fees paid by any Portfolio as a result of the BlackRock Sub-Advisory Agreements. Based on its considerations, the Board concluded that it was a reasonable allocation of fees for the pertinent Sub-Adviser to receive the portion of the advisory fee paid by each Portfolio to BlackRock Advisors, as noted above. After the independent directors deliberated in executive session, the entire Board, including the independent directors, approved each BlackRock Sub-Advisory Agreement, concluding that the sub-advisory fee was reasonable in relation to the services provided and that each BlackRock Sub-Advisory Agreement was in the best interests of each pertinent Portfolio's shareholders. 136 BlackRock Series Fund, Inc.
