BLACKROCK EUROFUND APRIL 30, 2007 A Letter to Shareholders Dear Shareholder In its first four months, 2007 could already be termed an eventful year for investors. For most financial markets, 2007 opened just as 2006 ended - on a positive trajectory. Then, at the end of February and into March, global equity markets registered their first significant decline since last summer. The market jitters were triggered by a significant setback in the Chinese market and were exacerbated by worries of a weakening economy, escalating geopolitical concerns and rising delinquencies in the subprime mortgage market. Still, underlying stock market fundamentals appeared quite sound, supported by a generally favorable global economic backdrop, tame inflation, slowing but still positive earnings growth, relatively low interest rates and attractive valuations. These conditions prevailed later, and the Dow Jones Industrial Average crossed the 13,000 mark for the first time in its history in late April. Not unlike the equity market, the bond market also experienced volatility as observers attempted to interpret mixed economic signals. A bond market rally (falling yields and rising prices) late last year reversed itself early in 2007 amid some transitory signs of economic strength. Overall, yields have fluctuated month to month but ended April little changed from the beginning of the year. However, compared to one year ago, yields on 30-year Treasury bonds fell 36 basis points (.36%) and 10-year yields fell 44 basis points, while prices correspondingly rose. For its part, the Federal Reserve Board (the Fed) has left the target short- term interest rate on hold at 5.25% since first pausing in its interest rate- hiking campaign on August 8, 2006. The central bankers continue to express concern about potential inflationary pressures, but also acknowledge signs of economic weakness. Given this relatively "balanced" assessment, most observers believe the Fed will keep interest rates on hold for now. Against this backdrop, most major market indexes posted positive returns for the annual and semi-annual reporting periods ended April 30, 2007: Total Returns as of April 30, 2007 6-month 12-month U.S. equities (Standard & Poor's 500 Index) + 8.60% +15.24% Small cap U.S. equities (Russell 2000 Index) + 6.86 + 7.83 International equities (MSCI Europe, Australasia, Far East Index) +15.46 +19.81 Fixed income (Lehman Brothers Aggregate Bond Index) + 2.64 + 7.36 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 1.59 + 5.78 High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) + 6.96 +11.72 If the first four months are any guide, 2007 could be a year of enhanced market volatility. As you navigate the un-certainties, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed. For more insight, we invite you to view "What's Ahead in 2007: An Investment Perspective" and "Are You Prepared for Volatility?" at www.blackrock.com/funds. We thank you for entrusting BlackRock with your investment assets, and we look forward to continuing to serve you in the months and years ahead. Sincerely, (Robert C. Doll, Jr.) Robert C. Doll, Jr. Fund President and Trustee THIS PAGE NOT PART OF YOUR FUND REPORT BLACKROCK EUROFUND APRIL 30, 2007 A Discussion With Your Fund's Portfolio Manager The Fund provided strong absolute performance for the period, but lagged the MSCI Europe Index's return, as its large-cap bias did not allow it to benefit from the robust merger-and-acquisition activity in European mid- and small-cap stocks. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended April 30, 2007, BlackRock EuroFund's Institutional, Institutional 1, Investor A, Investor B, Investor C and Class R Shares had total returns (in U.S. dollar terms) of +14.53%, +14.53%, +14.44%, +13.84%, +13.96% and +14.15%, 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 - 9 of this report to shareholders.) For the same period, the benchmark Morgan Stanley Capital International (MSCI) Europe Index returned +18.17% (net return in U.S. dollar terms), and the Fund's comparable Lipper category of European Region Funds posted an average return of +18.46%. (Funds in this Lipper category invest in equity securities whose primary trading markets or operations are concentrated in the European region or a single country within this region.) Equity markets delivered healthy returns for the majority of the period before suffering an abrupt correction at the end of February. The result was a broad- based global equity decline, but markets quickly recovered and by period-end had surpassed their previous highs. Despite looming concerns of a slowdown in U.S. economic growth and more recent concerns that a crisis in the U.S. subprime mortgage market could hurt economic growth, the global economy has remained on track. European companies have continued to deliver stronger-than-expected earnings growth and record profits, driven by a combination of robust export demand (especially from the faster-growing Asian economies) and a pick-up in domestic demand in Europe. In an environment of positive earnings momentum, central banks have remained active, with short-term interest rates moving higher in most regions. Both the European Central Bank (ECB) and Bank of England (BoE) have continued to nudge short-term rates higher in response to the healthier performance of the main European economies and a modest rise in consumer price inflation. However, monetary policy still remains accommodative, with inexpensive debt financing leading to abundant levels of global liquidity and fueling corporate activity. Mergers and acquisitions (M&A) have subsequently been a primary driver of market returns, especially in Europe where record corporate activity has been seen across a range of sectors. The oil price, having reached a new high of $77 per barrel in August 2006, declined to levels as low as $50 per barrel in January, but has since recovered. This decline was attributed to an exceptionally mild winter, increased global supply and concerns that a slowdown in global growth could impact demand. During the period, the Fund benefited from successful stock selection in the materials sector, particularly through its exposure to the steel industry, which has experienced robust global demand and increased pricing power, along with chemical companies. The Fund's holdings in Arcelor Mittal, Bayer AG and BASF AG were positive contributors to performance. An underweight position in the pharmaceuticals sector also aided the Fund's relative returns. The primary negative performance factor during the period was the Fund's exposure to the financials sector, especially in the banking subsector where the portfolio is overweight relative to its benchmark, the MSCI Europe Index. The sector has fallen amid market concerns about the sustainability of capital- markets-related revenue in the context of a slowing U.S. economy and subprime market fallout, along with worries that rising interest rates could impact retail loan growth. Over the last few months of the reporting period, M&A activity also was a negative factor in terms of Fund returns. Specifically, the Fund was negatively influenced by its avoidance of ABN Amro, which rose sharply after an unexpected bid from Barclays Plc was quickly followed by another offer from a consortium. This generated considerable speculation in the sector which has, in general, tended to hold back stock values of potential acquirers (typically large-cap banks to which the Fund is exposed) and raise the value of potential targets (mid cap names in which the Fund is underweight). BLACKROCK EUROFUND APRIL 30, 2007 Additional performance detractors included disappointing stock selection in the consumer discretionary sector and an overweight position in the energy sector. In consumer discretionary, the Fund's lack of ownership of Daimler Chrysler AG hurt relative results as the automaker's stock rose sharply after the company announced the sale of its struggling U.S. subsidiary, Chrysler. The Fund's overweight position in the energy sector also hindered performance as the sector fell in conjunction with the downward movement in oil prices. Finally, selected holdings in the telecommunications and retail sectors, along with a significant underweight in food, beverage & tobacco stocks, negatively impacted the Fund's relative results. What changes were made to the portfolio during the period? During the six-month period, we increased the Fund's exposure to the pharmaceuticals sector based on our view that valuations have become attractive after a period of underperformance that was the result of both political and research & development concerns. We established new positions in Novartis AG and Sanofi-Aventis, both of which offer strong product pipelines and good growth prospects. We also added to the food, beverage & tobacco and capital goods sectors through the purchase of household & personal goods manufacturer Unilever Plc, tobacco manufacturer British American Tobacco Plc, industrial conglomerate Siemens AG and construction company CRH Plc. These transactions were mostly funded by taking profits in telecommunications - a sector that had underperformed for most of 2005 and then experienced substantial earnings upgrades in the second half of 2006 as pricing remained resilient and cost-cutting began to positively impact profitability. Specifically, the Fund took profits in Teliasonera and reduced its position in Telecom Italia SpA. Within the financials sector, the Fund made a timely exit from U.K. bank HSBC Holdings Plc and Dutch bank/insurer ING Groep on concerns that a downward sloping yield curve would impact profitability, which it did. The proceeds from these sales were used to establish new positions in Spanish bank Banco Santander Central Hispano SA, which we believe offers one of the strongest growth stories in Europe through its exposure to Brazil and Mexico, along with Societe Generale and Intesa San Paulo. How would you characterize the Fund's position at the close of the period? At the end of the period, the Fund was overweight in financials (most notably banks, insurance companies and diversified financials), capital goods and utilities. The most significant underweights held in the portfolio were in media, information technology, hardware & equipment, consumer durables & apparel and food retail. We maintain our strategy of investing in stocks that we believe have relatively low valuations. Business and consumer confidence continues to improve in Europe, pointing to sustained momentum in economic growth during 2007. Encouragingly, growth has been driven by improving trends in domestic demand as well as robust export demand, which has resulted from lower unemployment and tighter labor markets, especially in the laggard economies such as Germany and Italy. Though we have seen an increase in interest rate hikes from central banks, the monetary policy environment remains accommodative and the combination of inexpensive credit, strong corporate earnings and attractive valuations should allow the market to make progress against what may be a more challenging international backdrop. James A. Macmillan Vice President and Portfolio Manager May 18, 2007 BLACKROCK EUROFUND APRIL 30, 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. Institutional 1 Shares commenced operations on November 6, 2006. 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. * Institutional 1 Shares are not subject to any sales charge. Institutional 1 Shares bear no ongoing distribution or service fees and are available only to shareholders of The Europe Fund, Inc. in connection with the reorganization and for dividend and capital gain reinvestment. These shares automatically converted to Institutional Shares on May 7, 2007. Prior to inception, Institutional 1 Share performance results are those of Institutional Shares. * 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 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 for 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 reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. The Fund may charge a 2% redemption fee for sales or exchanges of shares within 30 days of purchase or exchange. Performance data does not reflect this potential fee. 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 EUROFUND APRIL 30, 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 November 1, 2006 and held through April 30, 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.

See Notes to Financial Statements. BLACKROCK EUROFUND APRIL 30, 2007 Notes to Financial Statements (Unaudited) 1. Significant Accounting Policies: BlackRock EuroFund (the "Fund") 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 un-audited financial statements reflect all 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 without a sales charge and 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. Institutional 1 Shares were issued in connection with the Fund's acquisition of The Europe Fund Inc. on November 6, 2006. Institutional 1 Shares generally will not be available for purchase except for dividend and capital gain reinvestments for existing shareholders and automatically converted to Institutional Shares on May 7, 2007. 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 Trustees of the Fund. Long positions traded in 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 Trustees of the Fund. Short positions traded in the OTC markets are valued at the last available asked price. Portfolio securities that are traded both in the OTC markets and on a stock exchange are valued according to the broadest and most representative market. Options written and 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. 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. Effective April 2, 2007, securities purchased with a maturity of greater than 60 days may be valued at amortized cost. 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 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 Trustees of the Fund, 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 Fund under the general supervision of the Fund's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Fund. BLACKROCK EUROFUND APRIL 30, 2007 Notes to Financial Statements (continued) 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 Fund's Board of Trustees or by the Manager using a pricing service and/or procedures approved by the Fund's Board of Trustees. (b) 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. (c) Derivative financial instruments--The Fund may engage in various portfolio investment 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 due to an unfavorable change in the price of the underlying security or if the counterparty does not perform under the contract. The counterparty for certain instruments may pledge cash or securities as collateral. * 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. * Options--The Fund may write covered call options and put options and purchase put and call 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 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 Fund enters into a closing transaction), 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. (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. Interest income is recognized on the accrual basis. BLACKROCK EUROFUND APRIL 30, 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 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 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 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 Fund's financial statements, if any, is currently being assessed. 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. At this time, management is evaluating the implications of FAS 157 and its impact on the Fund's financial statements, if any, has not been determined. In addition, in February 2007, FASB issued "Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), which 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 Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, Merrill Lynch Investment Managers, L.P. ("MLIM") was the Fund's manager. The general partner of MLIM is Princeton Services, Inc.

For such services, the Fund pays a monthly fee at an annual rate of .75% on an annual basis of the average daily value of the Fund's net assets. In addition, the Manager has entered into sub-advisory agreements with BlackRock Investment Management, LLC ("BIM") and BlackRock Asset Management U.K. Limited, both affiliates of the Manager, under which the Manager pays each Sub-Adviser for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Fund to the Manager. Prior to September 29, 2006, MLIM had a Sub- Advisory Agreement with Merrill Lynch Asset Management U.K. Limited, an affiliate of MLIM. Pursuant to the Distribution Plan adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor ongoing service 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 an affiliate of each of the Distributors, provide shareholder servicing and distribution services to the Fund. The ongoing service fee compensates the Distributors 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.

Call Center Fees Institutional $ 2,085 Institutional 1 $ -- Investor A $ 5,725 Investor B $ 1,573 Investor C $ 610 Class R $ 18 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, an affiliate of the Manager, 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, 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 April 30, 2007, the Fund reimbursed the Manager $7,880 for certain accounting services. PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, is the Fund's transfer agent.

The Fund may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Fund may borrow up to the maximum amount allowable under the Fund's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Fund pays a commitment fee of .07% per annum based on the Fund's pro rata share of the unused portion of the credit agreement.
