BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 A Letter to Shareholders Dear Shareholder As the July reporting period closed, financial markets were rattled by ongoing problems in the credit markets, particularly those associated with the subprime mortgage industry. While this has been an issue for much of 2007, recent headlines and some high-profile credit collapses reignited concerns that credit problems could spill over into the broader economy and derail global financial markets. Although volatility has reared its head throughout the year, the fundamental market and economic backdrop has been little changed. U.S. economic activity has decelerated, led by a slowdown in the housing market, but economies outside the United States remain robust, which has been a boon for U.S. exports. Through July, the Federal Reserve Board had kept the target short-term interest rate on hold at 5.25%. For the most part, equities continued to find support in robust merger-and- acquisition activity, a healthy global economy, tame inflation, relatively low interest rates, still-positive earnings growth and attractive valuations. These tailwinds generally prevailed over such headwinds as the weakening U.S. economy, slowing housing market, escalating geopolitical concerns and high energy prices, leading the Standard & Poor's (S&P) 500 Index and the Dow Jones Industrial Average to post new record highs in mid-July before succumbing to the latest market correction. Meanwhile, mixed economic signals and the credit market debacle have made for a volatile backdrop for fixed income, with investors fleeing from bonds associated with the housing and credit markets in favor of higher-quality Treasury bonds. As a result, the 10-year Treasury yield, which touched 5.30% in June (its highest level in five years), fell to nearly 4.75% by period-end. Prices correspondingly rose, reflecting the investor flight to quality. Against this backdrop, financial markets posted mixed results for the six- month period ended July 31, 2007, but continued to exhibit relative strength when measured over the past year: Total Returns as of July 31, 2007 6-month 12-month U.S. equities (S&P 500 Index) +2.10% +16.13% Small cap U.S. equities (Russell 2000 Index) -2.47 +12.12 International equities (MSCI Europe, Australasia, Far East Index) +8.38 +23.91 Fixed income (Lehman Brothers U.S. Aggregate Bond Index) +1.86 + 5.58 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +1.17 + 4.27 High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) -1.75 + 6.44 Past performance is no guarantee of future results. Index performance shown for illustrative purposes only. You cannot invest directly in an index. We expect market volatility to linger through the remainder of 2007. As you navigate the uncertainties, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed.

Doll, Jr. Fund President and Director THIS PAGE NOT PART OF YOUR FUND REPORT BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 A Discussion With Your Fund's Portfolio Manager As a group, mid cap stocks performed strongly relative to both small and large cap stocks during the period, but stock-specific factors weighed on Fund results. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended July 31, 2007, BlackRock Mid Cap Value Opportunities Fund's Institutional, Investor A, Investor B, Investor C and Class R Shares had total returns of +1.06%, +0.95%, +0.53%, +0.54% and +0.76%, respectively. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 6 - 7 of this report to shareholders.) For the same period, the benchmark Standard & Poor's (S&P) MidCap 400 Index returned +3.40% and the Lipper Mid Cap Value Funds category posted an average return of +2.27%. (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.) U.S. equity markets weathered bouts of volatility throughout the six-month reporting period. A sharp market correction in late February was followed by a strong rally that sent the S&P 500 Index and the Dow Jones Industrial Average to new record highs in May. The upward momentum waned in the final two months of the period, when the broader-market S&P 500 Index and the benchmark S&P MidCap 400 Index posted negative monthly returns. The correction came amid growing investor concern over the deteriorating housing market, credit risk in the subprime mortgage segment and diminishing expectations for a near-term cut in the target federal funds rate. Against this backdrop, mid cap stocks outperformed both their small and large cap counterparts for the six-month period. We believe this can be attributed to the greater merger-and-acquisition (M&A) activity and the higher level of implied takeover premiums in mid cap stocks. In terms of style, growth outpaced value across the market-capitalization spectrum. For this reason, our relative value approach - where we look for stocks trading at the low end of their historical valuation ranges, rather than making decisions on an absolute price-to-earnings or price-to-book basis - proved advantageous. What factors most influenced Fund performance? Fund performance for the period was driven by stock-specific factors. Our stock picks in the information technology, energy and financials sectors generally lagged those in the S&P MidCap 400 Index, although the majority of the underperformance relative to the benchmark came from disappointing stock performance in the healthcare sector. Our position in Medicis Pharmaceutical Corp. underperformed the healthcare sector as the launch of a competitor's product led to worries regarding the company's market positioning. Nevertheless, with only two competitors in this emerging growth market, we expect favorable market growth and pricing trends. Medicis has other products, including a strong dermatology product line, in addition to a good balance sheet and record of solid execution. For this reason, we continue to own shares of Medicis. Our largest position in healthcare, King Pharmaceuticals, Inc., also hindered Fund performance following an unfavorable patent decision. If King's lead product goes generic this year, we believe that the other drugs in its portfolio more than make up for the currently depressed share price. Other stocks that detracted from the Fund's relative results included Friedman, Billings, Ramsey Group, Inc., which we had initially purchased for its investment banking/capital markets business. Friedman also owned a portfolio of subprime mortgages that it was looking to sell. The subprime market collapsed before the company could liquidate its portfolio, and we subsequently sold our entire position in Friedman on a small bounce in subprime stocks. Stocks that contributed favorably to the Fund's relative results included Medimmune, Inc., maker of respiratory and other immune-boosting drugs, and chemical company Huntsman Corp. Both Medimmune and Huntsman were the subject of takeover announcements. Our position in Dresser-Rand Group Inc., a manufacturer of compressors sold into the energy industry, also proved additive to performance. The company benefited from a substantial increase in orders and solid earnings. BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 What changes were made to the portfolio during the period? From a sector perspective, the biggest change involved an increase in exposure to the utilities sector, an area where we have seen some M&A activity. We previously had underweighted utilities, but the sector is beginning to look attractive again on valuation measures. New additions to the portfolio included Alliant Energy Corp., Wisconsin Energy Corp. and Puget Energy, Inc. We also raised the Fund's position in consumer discretionary stocks with the addition of direct marketing services company Harte-Hanks, Inc. and increased exposure to Newell Rubbermaid, Inc. and Jones Apparel Group, Inc. This was offset somewhat by a reduction in specialty retailers. In particular, we liquidated our position in RadioShack Corp. after sharp share price appreciation, and we reduced exposure to The Gap, Inc., as the shares rallied significantly on news that a new CEO had been hired. We believe meaningful improvement will take time, and prefer to wait on the sidelines for more tangible evidence of a turnaround. In financials, we favored the insurers and asset management companies, while we reduced exposure to commercial banks. Notable new additions to the portfolio included AMBAC Financial Group, Inc. in insurance, Waddell & Reed Financial, Inc. and Affiliated Managers Group, Inc. among the asset managers, and TD Ameritrade Holding Corp. in the online brokerage space. Sales included asset manager Janus Capital Group and commercial banks Compass Bancshares, Inc. and The Colonial BancGroup, Inc. Among real estate investment trusts (REITs), Crescent Real Estate EQT Co., one of the Fund's largest financial positions, appreciated on news that it would be acquired by Morgan Stanley Real Estate. We trimmed our exposure to Crescent while establishing a position in hotel REIT FelCor Lodging Trust, Inc. and adding to Alexandria Real Estate Equities, Inc., both of which have more attractive valuations, in our view, and no residential real estate exposure. Although the Fund's healthcare exposure decreased slightly during this six- month period, the sector has been an interesting area for new purchases. We have seen a lot of consolidation activity and believe that large cap pharmaceutical companies could acquire additional small players with emerging drug pipelines. We initiated positions in Sepracor, Inc., which focuses on respiratory and central nervous system drugs, and Imclone Systems, Inc., a bio- pharmaceutical company. Both stocks are attractive acquisition candidates for large cap pharmaceutical companies. On the sell side, we reined in our overweighting in energy as oil prices approached $80 per barrel. We also reduced our exposure to the industrials sector, where we saw strong performance in the aerospace & defense industry. We realized profits in Goodrich Corp., a supplier of aerospace components and systems, and sold our positions in W.W. Grainger and Chicago Bridge & Iron Co. after sharp share price appreciation. We reduced the Fund's overweight position in the information technology sector with the liquidation of Hyperion Solutions Corp., Novell, Inc., Computer Sciences Corp. and BISYS Group, among others, on takeovers that were either widely anticipated or actually announced. Finally, we moved to a zero weighting in the telecommunication services sector with the sale of our position in BCE, Inc., the leading communications company in Canada, which agreed to be acquired by a private consortium of investors. Consistent with our bottom-up stock-selection process, most portfolio activity during the period was driven by stock-specific considerations rather than top- down macroeconomic investment themes. How would you characterize the Fund's position at the close of the period? At July 31, 2007, the Fund was most overweight versus the S&P MidCap 400 Index in the financial services and information technology (IT) sectors, and most underweight in the industrials and consumer discretionary sectors. The Fund's largest absolute exposure at period-end was in financial services, though we recently reduced bank exposure in favor of information technology purchases, causing IT to rise to the second-largest sector on an absolute basis as of July 31, 2007. Mid cap stocks performed strongly relative to both small and large cap stocks during the six-month reporting period, but may be vulnerable amid concerns about rising financing costs and slowing M&A activity. Higher interest rates are likely to ease investor interest in mid cap names, and we expect that the pace of consolidation activity will slow. We have a more cautious long-term view, but continue to find attractive opportunities in specific mid cap companies. We ended the period with a fully invest portfolio and will continue to rebalance our positioning to mitigate risk. R. Elise Baum, CFA Portfolio Manager August 8, 2007 BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 Performance Data About Fund Performance Effective October 2, 2006, the Fund's Class A, Class B, Class C and Class I Shares were redesignated Investor A, Investor B, Investor C and Institutional Shares, respectively. Class R Shares did not change their designation. As previously communicated to shareholders, new sales charge schedules came into effect at the same time for certain of these classes. The Fund has multiple classes of shares: * Institutional Shares are not subject to any sales charge. Institutional Shares bear no ongoing distribution or service fees and are available only to eligible investors. * Investor A Shares incur a maximum initial sales charge (front-end load) of 5.25% and a service fee of 0.25% per year (but no distribution fee). * Investor B Shares are subject to a maximum contingent deferred sales charge of 4.50% declining to 0% after six years. In addition, Investor B Shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. These shares automatically convert to Investor A Shares after approximately eight years. (There is no initial sales charge for automatic share conversions.) All returns for periods greater than eight years reflect this conversion. * Investor C Shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. In addition, Investor C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. * Class R Shares do not incur a maximum initial sales charge (front-end load) or deferred sales charge. These shares are subject to a distribution fee of 0.25% per year and a service fee of 0.25% per year. Class R Shares are available only to certain retirement plans. Prior to inception, Class R Share performance results are those of Institutional Shares (which have no distribution or service fees) restated to reflect the Class R Share fees. Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com to obtain performance data current to the most recent month-end. Performance results do not include the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 Disclosure of Expenses Shareholders of this Fund 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 February 1, 2007 and held through July 31, 2007) is intended to assist shareholders both in calculating expenses based on an investment in the Fund 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 Fund'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 February 1, 2007 February 1, July 31, to July 31, 2007 2007 2007 Actual Institutional $1,000 $1,010.60 $ 4.59 Investor A $1,000 $1,009.50 $ 6.08 Investor B $1,000 $1,005.30 $10.09 Investor C $1,000 $1,008.90 $10.41 Class R $1,000 $1,007.60 $ 7.72 Hypothetical (5% annual return before expenses)** Institutional $1,000 $1,020.24 $ 4.61 Investor A $1,000 $1,018.75 $ 6.11 Investor B $1,000 $1,014.73 $10.14 Investor C $1,000 $1,014.44 $10.44 Class R $1,000 $1,017.11 $ 7.75 * For each class of shares of the Fund, expenses are equal to the annualized expense ratio for the class (.92% for Institutional, 1.22% for Investor A, 2.03% for Investor B, 2.09% for Investor C and 1.55% for Class R), multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period shown). ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year divided by 365.

Significant Accounting Policies: BlackRock Mid Cap Value Opportunities Fund (the "Fund") and BlackRock Mid Cap Value Opportunities Series, Inc. (the "Series") is registered under the Investment Company Act of 1940, as amended, as a diversified, open-end management investment company. The Fund's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. These unaudited financial statements reflect all such adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Fund offers multiple classes of shares. Institutional Shares are sold only to certain eligible investors. Investor A Shares are sold with a front-end sales charge. Shares of Investor B and Investor C may be subject to a contingent deferred sales charge. Class R Shares are sold only to certain retirement plans. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Investor A, Investor B, Investor C and Class R Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B, Investor C and Class R Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that investor B shareholders may vote on certain changes to the Investor A distribution plan). 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 Fund. (a) Valuation of investments--Equity securities held by the Fund 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 Series. Long positions traded in the over-the-counter ("OTC") markets, NASDAQ Capital Market or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Directors of the Series. Short positions traded in the OTC markets are valued at the last available asked price. Portfolio securities that are traded both in the OTC markets and on a stock exchange are valued according to the broadest and most representative market. 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 Fund 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. Valuation of short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Repurchase agreements are valued at cost plus accrued interest. The Fund employs pricing services to provide certain securities prices for the Fund. 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 Series, including valuations furnished by the pricing services retained by the Fund, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Series under the general supervision of the Series' Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Series. 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 Fund'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 Fund'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 Series' 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 Series' Board of Directors. BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 Notes to Financial Statements (continued) (b) Derivative financial instruments--The Fund may engage in various portfolio strategies both to increase the return of the Fund 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. The counterparty for certain instruments may pledge cash or securities as collateral. * Financial futures contracts--The Fund 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 Fund deposits, and maintains, as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. * Options--The Fund may write put and covered call options and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing trans-action), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. * Foreign currency options and futures--The Fund may also purchase or sell listed or OTC foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions may be effected with respect to hedges on non-U.S. dollar-denominated securities owned by the Fund, sold by the Fund but not yet delivered, or committed or anticipated to be purchased by the Fund. * Forward foreign exchange contracts--The Fund 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 Fund as an unrealized gain or loss. When the contract is closed, the Fund 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 or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Fund 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 Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. (e) Security transactions and investment income--Security transactions are recorded on the dates the trans-actions 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 Fund has determined the ex-dividend date. Upon notification from issuers, some of the dividend income received from a real estate investment trust ("REIT") may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income is recognized on the accrual basis. BLACKROCK MID CAP VALUE OPPORTUNITIES FUND JULY 31, 2007 Notes to Financial Statements (continued) (f) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (g) Dividends and distributions--Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (h) Securities lending--The Fund 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 Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund 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 Fund may pay reasonable finders, 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 Fund could experience delays and costs in gaining access to the collateral. The Fund 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 pronouncement--Effective June 29, 2007, the Fund implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including investment companies, before being measured and recognized in the financial statements. Management has evaluated the application of FIN 48 to the Fund, and has determined that the adoption of FIN 48 does not have a material impact on the Fund's financial statements. The Fund files U.S. and various state tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund's tax returns remains open for the years ended January 31, 2004 through January 31, 2007. 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 Fund's financial statements has not been determined. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. At this time, management is evaluating the implications of FAS 159 and its impact on the Fund's financial statements, if any, has not been determined. 2. Investment Advisory Agreement and Transactions with Affiliates: The Fund has entered into an Investment Advisory Agreement with the Manager. The Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate of BlackRock, Inc. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc.

For such services, the Fund pays a monthly fee of .65%, on an annual basis, of the average daily value of the Fund's net assets. 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 BIM for services it provides a monthly fee that is a percentage of the management fee paid by the Fund to the Manager. Pursuant to the Distribution Plans adopted by the Series in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor ongoing service fees and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: Service Distribution Fee Fee Investor A .25% -- Investor B .25% .75% Investor C .25% .75% Class R .25% .25% Pursuant to sub-agreements with each Distributor, broker-dealers, including Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill Lynch, and each Distributor provide shareholder servicing and distribution services to the Fund. The on-going service fee compensates the Distributor and each broker-dealer (including MLPF&S) for providing shareholder servicing to Investor A, Investor B, Investor C and Class R shareholders. The ongoing distribution fee compensates each Distributor and MLPF&S for providing shareholder and distribution-related services to Investor B, Investor C and Class R shareholders.

During the six months ended July 31, 2007, the following amounts have been accrued by the Fund to reimburse the Manager for costs incurred running the call center, which are a component of the transfer agent fees in the accompanying Statement of Operations. Call Center Fees Institutional $ 880 Investor A $2,250 Investor B $2,400 Investor C $2,490 Class R $ 290 The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to MLPF&S, or its affiliates.

Pursuant to that order, the Fund has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. BIM may, on behalf of the Fund, invest cash collateral received by the Fund 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 six months ended July 31, 2007, BIM received $20,160 in securities lending agent fees.
