UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM N-CSR CERTIFIED SHAREHOLDER REPORT OF REGISTERED MANAGEMENT INVESTMENT COMPANIES Investment Company Act file number 811-07885 Name of Fund: Master Enhanced Small Cap Series of Quantitative Master Series Trust Fund Address: P.O. Box 9011 Princeton, NJ 08543-9011 Name and address of agent for service: Robert C. Doll, Jr., Chief Executive Officer, Master Enhanced Small Cap Series of Quantitative Master Series Trust, 800 Scudders Mill Road, Plainsboro, NJ 08536. Mailing address: P.O. Box 9011, Princeton, NJ 08543-9011 Registrant's telephone number, including area code: (609) 282-2800 Date of fiscal year end: 12/31/06 Date of reporting period: 01/01/06 - 12/31/06 Item 1 - Report to Stockholders Master Enhanced Small Cap Series of Quantitative Master Series Trust Annual Report, December 31, 2006 A Discussion With Your Fund's Portfolio Managers During the annual period, Master Enhanced Small Cap Series of Quantitative Master Series Trust generated returns that were competitive with that offered by the benchmark Standard & Poor's (S&P) SmallCap 600 Index. 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, Master Enhanced Small Cap Series had a net total return of +15.23%. For the same period, the benchmark S&P Small Cap 600 Index returned +15.12%. Positive performance from our stock-substitution strategies was offset slightly by disappointing results from our stock-selection strategies. With respect to our stock-substitution strategies, performance benefited primarily from portfolio trading conducted in response to structural index changes. Merger arbitrage trading strategies also added favorably to performance. Regarding our stock-selection strategies, short interest and value signals drove positive performance, as did risk control positions. The primary detractors during the annual period were earnings quality, earnings surprise, external financing, price momentum and turn of the year signals. 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. Key highlights of the 12- 1 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 2 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 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 interest 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 smaller-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 3 that included reasonably good investment levels, healthy balance sheets and profit margins. 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 S&P Small Cap 600 Index, returned +15.12%, slightly behind the S&P 500 Index's +15.79% return but well ahead of the +10.32% return of the S&P MidCap 400 Index. In terms of sector performance, each of the 10 S&P 600 sectors posted positive returns for the 12-month period. The top performer was telecommunication services, which was up +34.93%, followed by materials and consumer staples, with respective returns of +30.13% and +28.74%. At the bottom were the consumer discretionary and health care sectors, with respective returns of +7.65% and +8.53%. What changes were made to the portfolio during the period? Throughout the fiscal year, as changes were made to the composition of the S&P Small Cap 600 Index, we purchased and sold securities to maintain the Series' objective of tracking the risks and return of the benchmark. We continued to use our quantitative stock-selection and stock-substitution strategies in an effort to generate returns above those offered by the index. The goal of our stock-selection process is to use quantitative techniques to determine whether a stock might outperform or underperform the market. We analyze each security by using quantitative screens that provide signals that ultimately inform our investment decisions. These signals may include earnings quality, 4 valuations, earnings surprises, external financing, short interest and price momentum factors, among others. We also apply stock-substitution strategies opportunistically as a value-added trading strategy. Our goal is to take advantage of temporary price strength in a security that might result from a corporate acquisition, corporate restructuring or index composition change. We also might employ convertible bond substitution when opportunities exist, taking a position in a company's convertible securities -- bonds that can be exchanged for shares of stock, in certain situations -- as a cheaper alternative to buying its equity shares. In December 2006, we implemented the turn of the year signal. We also removed the earnings surprise signal and increased the turn of the year signal exposure heading into year-end. 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 the market takes.

See Notes to Financial Statements. 24 Master Enhanced Small Cap Series NOTES TO FINANCIAL STATEMENTS 1. Significant Accounting Policies: Master Enhanced Small Cap Series (the "Series"), a non-diversified investment company, is part of Quantitative Master Series Trust (the "Trust"). The Trust is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interests in the Series, subject to certain limitations. The financial statements of the Series are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Series. (a) Valuation of investments - Equity securities that are held by the Series 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 Trust. 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 Trustees of the Trust. 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 Series 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 Series employs pricing services to provide certain securities prices for the Series. 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 Trust, including valuations furnished by the pricing services retained by the Trust, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Board of Trustees of the Trust. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. 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 assets of the Series 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 Series' net assets. 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 25 securities, those securities will be valued at their fair value as determined in good faith by the Trust's Board of Trustees or by the Manager using a pricing service and/or procedures approved by the Trust's Board of Trustees. (b) Derivative financial instruments - The Series may engage in various portfolio investment strategies to provide liquidity or as a proxy for a direct investment in securities underlying the Series' Index. 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 Series 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 Series deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series 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 Series as unrealized gains or losses. When the contract is closed, the Series 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 Series may purchase and write call and put options. When the Series writes an option, an amount equal to the premium received by the Series 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 Series enters into a closing transaction), the Series realizes a gain or loss on the option to the extent of the premiums received or paid (or loss or gain 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) Income taxes - The Series is classified as a partnership for federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. 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. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of Subchapter M of the Internal Revenue Code. (d) Security transactions and investment income - Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Interest income is recognized on the accrual basis. (e) 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 Series' financial statements, if any, is currently being assessed. 26 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 Series' financial statements has not been determined. 2. Investment Advisory Agreement and Transactions with Affiliates: On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates, including Fund Asset Management, L.P. ("FAM") 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., 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 September 29, 2006, shareholders of the investors of the Series approved a new Investment Advisory Agreement for the Trust 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 Trust and the Manager became effective on September 29, 2006. Prior to September 29, 2006, FAM was the Manager. The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Manager is responsible for the management of the Series' portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Series pays a fee at an annual rate of .01% of the average daily value of the Series' 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 the Sub-Advisor for services it provides a monthly fee at annual rate that is a percentage of the management fee paid by the Series to the Manager. In addition, MLPF&S received $3,647 in commissions on the execution of portfolio security transactions for the Series for the year ended December 31, 2006. For the year ended December 31, 2006, the Series reimbursed FAM and the Manager $4,064 and $1,128, respectively, for certain accounting services. Prior to September 29, 2006, certain officers and/or trustees of the Trust were officers and/or directors of MLIM, PSI, FAM, and/or Merrill Lynch. Commencing September 29, 2006, certain officers and/or trustees of the Trust 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 $387,972,732 and $378,151,474, respectively. 4. Short-Term Borrowings: The Trust on behalf of the Series, along with certain other funds managed by the Manager and its affiliates (or FAM and its affiliates), is a party to a $500,000,000 credit agreement with a group of lenders. The Series may borrow under the credit agreement to Series shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series' 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 Series pays a commitment fee of ..06% per annum based on the Series' 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 Series' election, the federal 27 funds rate plus .35% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the year ended December 31, 2006. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Investors and Board of Trustees of Quantitative Master Series Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Enhanced Small Cap Series, one of the portfolios constituting the Quantitative Master Series Trust (the "Trust"), as of December 31, 2006, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the respective periods then ended. These financial statements and financial highlights are the responsibility of the Trust'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 Trust is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting 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 Master Enhanced Small Cap Series of the Quantitative Master Series Trust as of December 31, 2006, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and its financial highlights for each of the respective periods then ended, in conformity with accounting principles generally accepted in the United States of America. Deloitte & Touche LLP Princeton, New Jersey February 26, 2007 28 QUANTITATIVE MASTER SERIES TRUST Master Enhanced Small Cap Series BlackRock Investment Advisory Agreement - Matters Considered by the Board The following disclosure appeared in the June 30, 2006 Semi-Annual Report of the Series and is the discussion referred to in "New BlackRock Sub-Advisory Agreement - Matters Considered by the Board" below. The term "Investment Adviser" as used herein refers to Fund Asset Management, L.P. New BlackRock Investment Advisory Agreement - Matters Considered by the Board In connection with the Transaction between Merrill Lynch and BlackRock, the Trust's Board of Trustees considered a new investment advisory agreement (the "New Investment Advisory Agreement") between the Trust 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 trustees, 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 trustees, 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 trustees consulted with their counsel and counsel for the Trust on numerous occasions, discussing, among other things, the legal standards and certain other considerations relevant to the trustees' deliberations. At the Board meetings, the trustees discussed with Merrill Lynch management and certain BlackRock representatives the Transaction, its strategic rationale and BlackRock's general plans and intentions regarding the Series and the Trust. At these Board meetings, representatives of Merrill Lynch and BlackRock made presentations to and responded to questions from the Board. The trustees 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 trustees 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 trustees 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 trustees 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 the Series and its shareholders by BlackRock Advisors, including compliance services; 29 o that operation of New BlackRock as an independent investment management firm will enhance its ability to attract and retain talented professionals; o that the Series should benefit from having access to BlackRock's state of the art technology and risk management analytic tools, including investment tools, provided under the BlackRock Solutions(R) brand name; o that BlackRock has no present intention to alter any applicable expense waivers or reimbursements currently in effect and, while it reserves the right to do so in the future, it would seek the approval of the Board before making any changes; o that in connection with the Transaction, Merrill Lynch and BlackRock have agreed to conduct, and use reasonable best efforts to cause their respective affiliates to conduct, their respective businesses in compliance with the conditions of Section 15(f) of the Investment Company Act of 1940 (the "1940 Act") in relation to any public funds advised by BlackRock or the Investment Adviser (or its affiliates), respectively; and o that Merrill Lynch and BlackRock would derive benefits from the Transaction and that, as a result, they have a different financial interest in the matters that were being considered than do Series shareholders. The trustees considered the information provided by Merrill Lynch and BlackRock above, and, among other factors, the following: o the potential benefits to Series 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 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 the Series' total advisory fees will not increase by virtue of the New Investment Advisory Agreement, but will remain the same; o that in May and August 2005, the Board had performed a full annual review of the investment advisory agreement currently in effect for the Series (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 the Series; and that the advisory and/or management fees paid by the Series, 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 trustees have considered relevant in the exercise of their reasonable judgment; and o that Merrill Lynch agreed to pay all expenses of the Series 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 30 Investment Advisory Agreement and as a result the Series would bear no 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 the Series 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 were: (a) fees (in addition to management fees) to be paid to BlackRock Advisors and its affiliates by the Series; (b) operating expenses of the Series paid to third parties; (c) the resources devoted to and compliance reports relating to the investment objective, policies and restrictions of the Series, and its compliance with the Trust's 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. These materials included (a) information compiled by Lipper on the fees and expenses and the investment performance of the Series as compared to a comparable group of funds as classified by Lipper; (b) a discussion by the portfolio management team for the Series on investment strategies used by the Series 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 Series and the Trust; and (d) information provided by the Investment Adviser concerning services related to the valuation and pricing of portfolio holdings of the Series, allocation of brokerage fees, portfolio turnover statistics, and direct and indirect benefits to the Investment Adviser and its affiliates from their relationship with the Series and the Trust. In their deliberations, the trustees 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 trustees did not identify any particular information that was all-important or controlling, and each trustee attributed different weights to the various factors. The trustees, including a majority of the independent trustees, 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 Series, and that the New Investment Advisory Agreement should be approved and recommended to Series 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 the Series, 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 the investment performance of the Series, but also considered certain areas in which both the Investment Adviser and the Series receive services as part of the Merrill Lynch complex. The Board compared the performance of the Series - both including and excluding the effects of fees and expenses - to the performance of a comparable group of 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 trustees considered, among other things, the expected impact of the Transaction on the 31 operations, facilities, organization and personnel of BlackRock Advisors and how it would affect the Series; the ability of BlackRock Advisors to perform its duties after the Transaction; and any anticipated changes to the current investment and other practices of the Series. The trustees were given information with respect to the potential benefits to the Series 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 trustees were advised that, as a result of Merrill Lynch's equity interest in BlackRock after the Transaction, the Trust 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 trustees 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 trustees determined that the nature and quality of services to be provided to the Series 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 trustees 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 trustees 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 the Series under the New Investment Advisory Agreement. Costs of Services Provided and Profitability. It was noted that, in conjunction with the recent review of the Current Investment Advisory Agreement, the trustees had received, among other things, a report from Lipper comparing the fees, expenses and performance of the Series 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 the contractual management fee rate and actual management fee rate of the Series 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 the total expenses of the Series to those of other comparable funds. The information showed that the Series had fees and expenses within the range of fees and expenses of comparable funds. The Board concluded that the management fee and fee rate and overall expense ratio of the Series 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 trustees 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 rates of compensation, the trustees determined that the Transaction should not increase the total fees payable, including any fee waivers and expense reimbursements, for advisory and administrative services. The trustees noted that it was not possible to predict with certainty New BlackRock's future profitability from its relationship with the Series. The trustees discussed with BlackRock Advisors its general methodology to be used in determining New BlackRock's profitability with respect to its relationship with the Series and the Trust. The trustees noted that they expect to receive profitability information from New BlackRock on at least an annual basis and thus be 32 in a position to evaluate whether any adjustments in fees and/or fee breakpoints of the Series 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 the Series increase and whether there should be changes in the management fee rate or structure in order to enable the Series to participate in these economies of scale. The Board determined that changes were not currently necessary and that the Series appropriately participated in these economies of scale. In reviewing the Transaction, the trustees 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 trustees determined that as a result of the Transaction, the total advisory fees of the Series would be no higher than the fees under the Current Investment Advisory Agreement. The trustees noted that in conjunction with their most recent deliberations concerning the Current Investment Advisory Agreement, the trustees had determined that the total fees for advisory and administrative services for the Series 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 trustees had received, among other things, a report from Lipper comparing the fees, expenses and performance of the Series 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 trustees concluded that, because the rates for advisory for the Series 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 trustees 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 approval or continuance of the Current Investment Advisory Agreement, and their discussions with management of the Investment Adviser and BlackRock, the trustees determined that those benefits could include increased ability for BlackRock to distribute shares of its funds and other investment products and to obtain research services using the Series' portfolio transaction brokerage commissions. The trustees 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 trustees considered investment performance for the Series. The trustees compared the Series' performance -- both including and excluding the effects of fees and expenses -- to the performance of a comparable group of funds, and the performance of a relevant index or combination of indexes. The comparative information received from Lipper showed Series 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 trustees believed the performance of the Series was satisfactory. Also, the trustees 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 the Series. Conclusion. After the independent trustees of the Trust deliberated in executive session, the entire Board, including the independent trustees, approved the New Investment Advisory Agreement on behalf of the Series, concluding that the advisory fee rate was reasonable in relation to the services provided and that the 33 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 Trustees, including the independent trustees, 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 the Series operates 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 a series and its shareholders that the BlackRock Sub-Adviser assist in managing the operations of the series 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 Adviser. The Investment Adviser would pay the BlackRock Sub-Adviser out of its own resources. There would be no increase in Series 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 the Series 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 the operations and administration of the Series and the BlackRock Sub-Adviser would provide advisory services to the Series 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 total advisory fees paid by the Series would not 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 the Series to the Investment Adviser. After the independent trustees deliberated in executive session, the entire Board, including the independent trustees, approved the Contingent Sub-Advisory Agreement, concluding that the advisory fee was reasonable in relation to the services provided and that the Contingent Sub-Advisory Agreement was in the best interests of shareholders. New BlackRock Sub-Advisory Agreement - Matters Considered by the Board At an in-person meeting held on August 16-17, 2006, the Board of Trustees, including the independent trustees, discussed and approved the sub-advisory agreement with respect to the Series between BlackRock Advisors, LLC (previously organized as BlackRock Advisors, Inc.) ("BlackRock Advisors") and BlackRock Investment Management, LLC (the "Sub-Adviser") (the "BlackRock Sub-Advisory Agreement"). The BlackRock Sub-Advisory Agreement became effective on September 29, 2006, at the same time the New Investment Advisory Agreement with BlackRock Advisors (which had been approved by the Series' shareholders) became effective. Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a monthly fee from BlackRock Advisors at an annual rate equal to 74% of the advisory fee received by BlackRock Advisors from the Series. BlackRock Advisors pays the Sub- 34 Adviser out of its own resources, and there is no increase in Series expenses as a result of the BlackRock Sub-Advisory Agreement. In approving the BlackRock Sub-Advisory Agreement at the August 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, and came to the same conclusions. In reviewing the sub-advisory fee rate provided for in the BlackRock Sub-Advisory Agreement, the Board noted the fact that both BlackRock Advisors and the 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 the Series and for oversight of the Series' operations and administration. Under the BlackRock Sub-Advisory Agreement, the Sub-Adviser provides advisory services to the Series and is responsible for the day-to-day management of the Series' portfolio. The Board also took into account the fact that there is no increase in total advisory fees paid by the Series as a result of the BlackRock Sub-Advisory Agreement. Based on its considerations, the Board concluded that it was a reasonable allocation of fees for the Sub-Adviser to receive a fee at an annual rate equal to 74% of the advisory fee paid by the Series to BlackRock Advisors. 35 Officers and Trustees Number of Funds and Portfolios in Other Public Position(s) Length Fund Complex Directorships Held with Of Time Overseen by Held by Name Address & Age Trust Served Principal Occupation(s) During Past 5 Years Trustee Trustee ==================================================================================================================================== Interested Trustees - ------------------------------------------------------------------------------------------------------------------------------------ Robert C.

Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting.
