BLACKROCK LARGE CAP VALUE EQUITY PORTFOLIO,
A PORTFOLIO OF BLACKROCK FUNDS ^SM

Wilmington, Delaware 19809
(800) 441-7762

June 15, 2006

Dear Shareholder:

        You are cordially invited to attend a special shareholder meeting (the “Special Meeting”) of BlackRock Large Cap Value Equity Portfolio (the “BlackRock Fund”), a portfolio of BlackRock Funds ^SM (“BlackRock Funds”), to be held on Tuesday, August 22, 2006. Before the Special Meeting, I would like to provide you with additional background and ask for your vote on an important proposal affecting the BlackRock Fund.

        The proposal you will be asked to consider at the meeting, as described in the enclosed Combined Prospectus/Proxy Statement, is the proposed reorganization (the “Reorganization”) of the BlackRock Fund into Merrill Lynch Large Cap Value Fund (the “ML Fund”), a series of Merrill Lynch Large Cap Series Funds, Inc., a fund with an investment objective and investment policies similar to those of the BlackRock Fund. As you know, the BlackRock Fund is advised by BlackRock Advisors, Inc., a subsidiary of BlackRock, Inc. (“BlackRock”). When the transaction between Merrill Lynch Investment Managers, L.P. (“MLIM”) and BlackRock (as discussed below) is completed, the ML Fund will be managed by BlackRock Advisors, Inc. or its successor (“BlackRock Advisors”) and it is expected to be renamed BlackRock Large Cap Value Fund. It is a condition to the closing of the Reorganization that the transaction between MLIM and BlackRock shall have been completed. MLIM, BlackRock or their affiliates will pay all expenses of completing the Reorganization, including proxy solicitation costs. As a result, the shareholders of the BlackRock Fund will not bear the costs of the Reorganization.

        The proposal you will be asked to consider at the meeting arises from the agreement by Merrill Lynch & Co., Inc. (“Merrill Lynch”), to combine MLIM and certain affiliates with BlackRock, one of the largest publicly traded investment management firms in the United States, to form a new asset management company that will be one of the world’s preeminent, diversified global money management organizations with approximately $1 trillion in assets under management. Based in New York, BlackRock currently manages assets for institutional and individual investors worldwide through a variety of equity, fixed income, cash management and alternative investment products. The new company will operate under the BlackRock name and be governed by a board of directors with a majority of independent members. The new company will offer a full range of equity, fixed income, cash management and alternative investment products with strong representation in both retail and institutional channels, in the United States and in non-U.S. markets. It will have over 4,500 employees in 18 countries and a major presence in most key markets, including the United States, the United Kingdom, Asia, Australia, the Middle East and Europe. The transaction has been approved by the boards of directors of Merrill Lynch, BlackRock and The PNC Financial Services Group, Inc., BlackRock’s current majority shareholder, and is expected to close at the end of the third quarter of 2006.

        This proposed Reorganization is part of the effort to consolidate certain of the comparable MLIM and BlackRock mutual funds to eliminate redundancies and achieve certain operating efficiencies.

        The Board of Trustees of BlackRock Funds believes the Reorganization is in the best interests of the BlackRock Fund and its shareholders, and unanimously recommends that you vote “For” the proposed Reorganization.

        I encourage you to carefully review the enclosed materials, which explain this proposal in more detail. As a shareholder, your vote is important, and we hope that you will respond today to ensure that your shares will be represented at the Special Meeting. You may vote using one of the methods below by following the instructions on your proxy card:

        If you do not vote using one of these methods, you may be called by Computershare Fund Services, our proxy solicitor, to vote your shares over the phone.

        As always, we appreciate your support.

Please vote now. Your vote is important.

To avoid the wasteful and unnecessary expense of further solicitation, we urge you to promptly indicate your voting instructions on the enclosed proxy card, date and sign it and return it in the envelope provided, or record your voting instructions by telephone or via the internet, no matter how large or small your holdings may be. If you submit a properly executed proxy but do not indicate how you wish your shares to be voted, your shares will be voted “For” the Reorganization. If your shares are held through a broker, you must provide voting instructions to your broker about how to vote your shares in order for your broker to vote your shares at the Special Meeting.

QUESTIONS & ANSWERS

        We recommend that you read the complete Combined Prospectus/Proxy Statement. For your convenience, we have provided a brief overview of the issue to be voted on.

Q: Why is a shareholder meeting being held?

A: You are being asked to approve an agreement and plan of reorganization (the “Reorganization”) between BlackRock Large Cap Value Equity Portfolio (the “BlackRock Fund”), a portfolio of BlackRock Funds ^SM (“BlackRock Funds”), and Merrill Lynch Large Cap Value Fund (the “ML Fund”), a series of Merrill Lynch Large Cap Series Funds, Inc., a fund that pursues an investment objective and investment policies similar to that of the BlackRock Fund. If the proposed Reorganization is approved and completed, an account at the ML Fund will be set up in your name, you will become a shareholder of the ML Fund and the BlackRock Fund will be terminated as a series of BlackRock Funds. Please refer to the Combined Prospectus/Proxy Statement for a detailed explanation of the proposed Reorganization and for a more complete description of the ML Fund.

The Reorganization arises from the agreement by Merrill Lynch & Co., Inc. (“Merrill Lynch”), to combine Merrill Lynch Investment Managers, L.P. (“MLIM”) and certain affiliates, with BlackRock, Inc. (“BlackRock”), one of the largest publicly traded investment management firms in the United States, to form a new asset management company that will be one of the world’s preeminent, diversified global money management organizations with approximately $1 trillion in assets under management. The Reorganization is part of a larger initiative to consolidate certain of the comparable MLIM and BlackRock mutual funds to eliminate redundancies and achieve certain operating efficiencies. As you know, the BlackRock Fund is advised by BlackRock Advisors, Inc., a subsidiary of BlackRock. When the transaction between MLIM and BlackRock is completed, the ML Fund will be managed by BlackRock Advisors, Inc. or its successor (“BlackRock Advisors”) and it is expected to be renamed BlackRock Large Cap Value Fund. MLIM, BlackRock or their affiliates will pay all expenses of completing the Reorganization, including proxy solicitation costs. As a result, the shareholders of the BlackRock Fund will not bear the costs of the Reorganization. It is a condition to the closing of the Reorganization that the transaction between MLIM and BlackRock shall have been completed.

BlackRock is one of the largest publicly traded investment management firms in the United States with approximately $463 billion in assets under management as of March 31, 2006. Based in New York, BlackRock currently manages assets for institutional and individual investors worldwide through a variety of equity, fixed income, cash management and alternative investment products. The new company will operate under the BlackRock name and be governed by a board of directors with a majority of independent members. The new company will offer a full range of equity, fixed income, cash management and alternative investment products with strong representation in both retail and institutional channels, in the United States and in non-U.S. markets. It will have over 4,500 employees in 18 countries and a major presence in most key markets, including the United States, the United Kingdom, Asia, Australia, the Middle East and Europe. The transaction has been approved by the boards of directors of Merrill Lynch, BlackRock and The PNC Financial Services Group, Inc., BlackRock’s current majority shareholder, and is expected to close at the end of the third quarter of 2006.

Q: How does the Board of Trustees suggest that I vote?

A: After careful consideration, the Board of Trustees of BlackRock Funds (the “BlackRock Fund Board”) has determined that the proposed Reorganization will benefit the shareholders of the BlackRock Fund and recommends that you cast your vote “For” the proposed Reorganization.

Q: How will the Reorganization affect me?

A: If shareholders of the BlackRock Fund approve the proposed Reorganization, substantially all the assets and certain stated liabilities of the BlackRock Fund will be combined with those of the ML Fund and you will become a shareholder of the ML Fund. An account will be set up in your name at the ML Fund and you will receive the same or a similar class of shares of the ML Fund as you currently hold of the BlackRock Fund. The aggregate net asset value of the shares you receive in the Reorganization will equal the aggregate net asset value of the shares you own immediately prior to the Reorganization. As a result of the Reorganization, however, a shareholder of the BlackRock Fund will hold a smaller percentage of ownership in the combined fund than he or she held in the BlackRock Fund prior to the Reorganization.

Q: In the Reorganization, will I receive shares of the ML Fund of the same class as the shares of the BlackRock Fund that I now hold?

A: You will receive shares of the ML Fund of the same or a similar class as the shares you own of the BlackRock Fund.

Q: Will I own the same number of shares of the ML Fund as I currently own of the BlackRock Fund?

A: No, you will receive shares of the ML Fund with the same aggregate net asset value as the shares of the BlackRock Fund you own prior to the Reorganization. However, the number of shares you receive will depend on the relative net asset value of the shares of the two Funds on the closing date. Thus, on the closing date, if the net asset value of a share of the ML Fund is lower than the net asset value of the corresponding share of the BlackRock Fund, you will receive a greater number of shares of the ML Fund in the Reorganization than you held in the BlackRock Fund before the Reorganization. On the other hand, if the net asset value of a share of the ML Fund is higher than the net asset value of the corresponding share of the BlackRock Fund, you will receive fewer shares of the ML Fund in the Reorganization than you held in the BlackRock Fund before the Reorganization. The aggregate net asset value of your ML Fund shares immediately after the Reorganization will be the same as the aggregate net asset value of your BlackRock Fund shares immediately prior to the Reorganization.

Q: Will my privileges as a shareholder change after the Reorganization?

A: Your rights as a shareholder will not change in any substantial way as a result of the Reorganization. In addition, the shareholder services available to you after the Reorganization will be substantially the same or may become more favorable.

Q: Who will advise the ML Fund once the Reorganization is completed?

A: The ML Fund will be managed by BlackRock Advisors, a wholly-owned subsidiary of BlackRock, pursuant to an investment advisory agreement to be entered into following the completion of the transaction between MLIM and BlackRock.

Q: Will I have to pay any sales load, commission or other similar fee in connection with the Reorganization?

A: No, you will not pay any sales load, commission or other similar fee in connection with the Reorganization. As more fully discussed in the Combined Prospectus/Proxy Statement, the holding period with respect to any contingent deferred sales charge that applies to shares of the ML Fund acquired by you in the Reorganization will be measured from the earlier of the time (i) you purchased your BlackRock Fund shares or (ii) you purchased your shares of any other BlackRock fund and subsequently exchanged them for shares of the BlackRock Fund.

Q: How do operating expenses paid by the ML Fund compare to those payable by the BlackRock Fund?

While the projected net operating expenses of certain classes of shares are expected to be slightly lower, the projected net operating expenses of certain other classes of shares of the combined fund are expected to be higher than those of the BlackRock Fund prior to the Reorganization. Based on several factors as described in the accompanying Combined Prospectus/Proxy Statement (including, among other things, the investment policies of each Fund, the composition of the investment team that will manage the combined fund, the relatively small size of the BlackRock Fund compared to the ML Fund and the superior performance history of the ML Fund over time compared to the BlackRock Fund), BlackRock Funds’ Trustees have approved the proposed Reorganization believing it will benefit shareholders of the BlackRock Fund and they recommend that you cast your vote “For” the proposed Reorganization, notwithstanding the expected impact on net operating expenses.

Q: What will I have to do to open an account in the ML Fund? What happens to my account if the Reorganization is approved?

A: If the Reorganization is approved, an account will be set up in your name and your shares automatically will be converted into shares of the ML Fund, and we will send you written confirmation that this change has taken place. You will receive the same or a similar class of shares of the ML Fund as you currently hold of the BlackRock Fund. The aggregate net asset value of the shares you receive in the Reorganization will be equal to the aggregate net asset value of the shares you own immediately prior to the Reorganization. No certificates for shares will be issued in connection with the Reorganization. If you currently hold certificates representing your shares of the BlackRock Fund, it is not necessary to surrender such certificates.

Q: Will I have to pay any federal taxes as a result of the Reorganization?

A: The Reorganization is expected to qualify as a tax-free “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. If the Reorganization so qualifies, in general, the BlackRock Fund will not recognize any gain or loss as a result of the transfer of all of substantially its assets and certain stated liabilities in exchange solely for shares of the ML Fund or as a result of its liquidation, and you will not recognize any gain or loss upon your receipt solely of shares of the ML Fund in connection with the Reorganization.

Q: What if I redeem or exchange my shares before the Reorganization takes place?

A: If you choose to redeem or exchange your shares before the Reorganization takes place, the redemption or exchange will be treated as a normal redemption or exchange of shares and, generally, will be a taxable transaction and any applicable redemption fees will be applied. Also, in the case of redemptions, any applicable contingent deferred sales charges will be applied.

Q: How do I vote my proxy?

A: You may cast your vote by mail, telephone or internet or in person at the special shareholder meeting. To vote by mail, please mark your vote on the enclosed proxy card and sign, date and return the card in the postage-paid envelope provided. To vote by telephone or over the internet, please have the proxy card in hand and call the telephone number or go to the website address listed on the proxy card and follow the instructions.

Q: When will the Reorganization occur?

A: If approved by shareholders, the Reorganization is expected to occur contemporaneously with or soon after the transaction between MLIM and BlackRock, which is expected to occur at the end of the third quarter of 2006. The Reorganization will not take place if for any reason the transaction between MLIM and BlackRock does not occur or if the Reorganization is not approved by BlackRock Fund shareholders at the Special Meeting.

Q: Whom do I contact for further information?

A: You can contact your financial adviser for further information. You may also call Computershare Fund Services, our proxy solicitor, at 1-866-390-5114 or visit our website at www.blackrock.com where you can send us an email message by selecting “Contact Us.”

        This Combined Prospectus/Proxy Statement is furnished to you as a shareholder of the BlackRock Large Cap Value Equity Portfolio (the “BlackRock Fund”). A special meeting of shareholders of the BlackRock Fund (the “Special Meeting”) will be held at the Omni Berkshire Place, 21 East 52nd Street, New York, New York 10022, on Tuesday, August 22, 2006 at 11:00 a.m., Eastern time, to consider the items that are listed below and discussed in greater detail elsewhere in this Combined Prospectus/Proxy Statement. Shareholders of record of the BlackRock Fund at the close of business on May 25, 2006 (the “Record Date”) are entitled to notice of, and to vote at, the Special Meeting or any adjournments thereof. This Combined Prospectus/Proxy Statement, proxy card and accompanying Notice of Special Meeting of Shareholders were first sent or given to shareholders of the BlackRock Fund on or about June 23, 2006. Whether or not you expect to attend the Special Meeting or any adjournment thereof, the Board of Trustees of BlackRock Funds requests that shareholders vote their shares by completing and returning the enclosed form of proxy.

        The purposes of the Special Meeting are:

        The Board of Directors of ML Series, on behalf of the ML Fund (the “ML Fund Board”), and the Board of Trustees of BlackRock Funds, on behalf of the BlackRock Fund (the “BlackRock Fund Board”), have each approved a reorganization (the “Reorganization”) by which the BlackRock Fund, a separate series of BlackRock Funds, an open-end investment company, would be acquired by the ML Fund, a separate series of ML Series, an open-end investment company. The ML Fund has an investment objective and investment policies and practices similar to those of the BlackRock Fund. The Reorganization arises from the agreement by Merrill Lynch & Co., Inc. (“Merrill Lynch”), to combine Merrill Lynch Investment Managers, L.P. (“MLIM”) and certain affiliates with BlackRock, Inc. (“BlackRock”) to form a new asset management company. The Reorganization is part of a larger initiative to consolidate certain of the comparable MLIM and BlackRock funds to eliminate redundancies and achieve certain operating efficiencies. As you know, the BlackRock Fund is advised by BlackRock Advisors, Inc., a subsidiary of BlackRock. When the transaction between MLIM and BlackRock is completed, the ML Fund will be managed by BlackRock Advisors, Inc. or its successor (“BlackRock Advisors”) and it is expected to be renamed BlackRock Large Cap Value Fund. It is a condition to the closing of the Reorganization that the transaction between MLIM and BlackRock shall have been completed.

        The ML Fund and the BlackRock Fund are sometimes referred to herein each as a “Fund” and collectively as the “Funds.”

Funds. When the Reorganization is complete, BlackRock Fund shareholders will hold the same or a similar class of shares of the ML Fund as they currently hold of the BlackRock Fund. The aggregate net asset value of the ML Fund shares received in the Reorganization will equal the aggregate net asset value of the BlackRock Fund shares held immediately prior to the Reorganization. As a result of the Reorganization, however, a shareholder of the BlackRock Fund will hold a smaller percentage of ownership in the combined fund than such shareholder held in the BlackRock Fund prior to the Reorganization. After the Reorganization, the ML Fund will continue to operate as a separate series of ML Series, a registered open-end investment company. However, as discussed above, when the transaction between MLIM and BlackRock is completed, the ML Fund will be managed by BlackRock Advisors and it is a condition to the closing of the Reorganization that the transaction between MLIM and BlackRock shall have been completed.

TABLE OF CONTENTS

SUMMARY

        The following is a summary of certain information contained elsewhere in this Combined Prospectus/Proxy Statement and is qualified in its entirety by reference to the more complete information contained herein. Shareholders should read the entire Combined Prospectus/Proxy Statement carefully.

        BlackRock Funds and ML Series are both open-end management investment companies registered with the SEC. The BlackRock Fund is organized as a separate series of BlackRock Funds, a business trust organized under the laws of the Commonwealth of Massachusetts. The ML Fund is organized as a separate series of ML Series, a corporation organized under the laws of the State of Maryland. The ML Fund is organized in a “master/feeder” structure and is a feeder fund that invests all of its assets in a portfolio, the Master Large Cap Value Portfolio (the “Master Portfolio”), of Master Large Cap Series Trust (the “Master Trust”), that has the same investment objective and strategies as the ML Fund. Investment management arrangements are at the Master Trust level. In the Reorganization, the assets acquired by the ML Fund from the BlackRock Fund will be contributed to the Master Portfolio in exchange for interests in the Master Portfolio.

        The investment objective of the BlackRock Fund is to seek long-term capital appreciation, with current income as a secondary objective. The investment objective of the ML Fund is long-term capital growth. Each Fund publicly offers its shares on a continuous basis, and shares may be purchased through each Fund’s distributor, BlackRock Distributors, Inc. or FAM Distributors, Inc., respectively, and numerous intermediaries. Shareholders of each Fund (other than holders of the BlackRock Fund’s Institutional and Service Shares) have the right to exchange their shares for shares of the same class of other funds managed by the same adviser, subject to certain limitations. Additionally, each Fund permits its shareholders to redeem their shares at any time upon proper notice (subject, in certain cases, to contingent deferred sales charges and redemption fees).

The Proposed Reorganization

        The BlackRock Fund Board, including the Trustees who are not “interested persons” of BlackRock Funds (as defined in the 1940 Act), has unanimously approved the Reorganization Agreement. The ML Fund Board, including the Directors who are not “interested persons” of the ML Fund, and the Master Trust Board, including the Trustees who are not “interested persons” of the Master Trust, have also unanimously approved the Reorganization Agreement. Subject to approval by the BlackRock Fund shareholders, the Reorganization Agreement provides for:

        If the proposed Reorganization is approved and completed, BlackRock Fund shareholders would hold shares of the same or a similar class of the ML Fund as they currently hold of the BlackRock Fund with an aggregate net asset value equal to the aggregate net asset value of BlackRock Fund shares owned immediately prior to the Reorganization.

Background and Reasons for the Proposed Reorganization

        The Reorganization arises from the agreement by Merrill Lynch to combine MLIM and certain affiliates, including Fund Asset Management, L.P. (“FAM”) with BlackRock, one of the largest publicly traded investment management firms in the United States, to form a new asset management company that will be one of the world’s preeminent, diversified global money management organizations with approximately $1 trillion in assets under management. The Reorganization is part of a larger initiative to consolidate certain of the comparable MLIM and BlackRock mutual funds in order to eliminate redundancies and achieve certain operating efficiencies. As you know, the BlackRock Fund is advised by BlackRock Advisors, a subsidiary of BlackRock. The Master Portfolio is currently advised by FAM, an affiliate of MLIM. When the transaction between MLIM and BlackRock is completed, the Master Portfolio will be managed by BlackRock Advisors. After the Reorganization, the ML Fund is expected to be renamed BlackRock Large Cap Value Fund. It is a condition to the closing of the Reorganization that the transaction between MLIM and BlackRock shall have been completed.

        BlackRock is one of the largest publicly traded investment management firms in the United States with approximately $463 billion of assets under management as of March 31, 2006. Based in New York, BlackRock currently manages assets for institutional and individual investors worldwide through a variety of equity, fixed income, cash management and alternative investment products. The new company will operate under the BlackRock name and be governed by a board of directors with a majority of independent members. Merrill Lynch will hold no more than a 49.8% economic stake and a 45% voting interest in the new company, and the common stock interest of BlackRock’s current majority shareholder, The PNC Financial Services Group, Inc. (“PNC”), will be diluted to about 34%. Each of Merrill Lynch and PNC has agreed that it will vote all of its shares in accordance with the recommendation of the new company’s board of directors on all matters, including election of directors. The new company will offer a full range of equity, fixed income, cash management and alternative investment products with strong representation in both retail and institutional channels, in the U.S. and in non-U.S. markets. It will have over 4,500 employees in 18 countries and a major presence in most key markets, including the United States, the United Kingdom, Asia, Australia, the Middle East and Europe. The transaction has been approved by the boards of directors of Merrill Lynch, BlackRock and PNC and is expected to close at the end of the third quarter of 2006.

        In approving the Reorganization Agreement, the BlackRock Fund Board, including the independent Trustees, determined that participation in the Reorganization is in the best interests of the BlackRock Fund and its shareholders and that the interests of the shareholders of the BlackRock Fund will not be diluted with respect to net asset value as a result of the Reorganization. Before reaching these conclusions, the BlackRock Fund Board, including the independent Trustees, engaged in a thorough review process relating to the proposed Reorganization. As part of this process, the independent Trustees formed an ad hoc committee (the “Ad Hoc Committee”) which requested and received materials and information from BlackRock and Merrill Lynch in connection with their consideration of the Reorganization Agreement. The independent Trustees also received a memorandum outlining, among other things, the legal standards and certain other considerations relevant to the BlackRock Fund Board’s deliberations. The Ad Hoc Committee and its independent counsel held in person meetings on March 8, 2006 and March 27, 2006 to meet with senior executives of BlackRock, as well as certain key MLIM executives and investment professionals, to review the proposed Reorganization. The full BlackRock Fund Board held a telephonic meeting on April 21, 2006, at which matters relating to the Reorganization were further discussed. The BlackRock Fund Board, including all of the independent Trustees, approved the Reorganization at a quarterly in person meeting that was held on May 16, 2006.

        The primary factors considered by the BlackRock Fund Board with regard to the Reorganization include, but are not limited to, the following:

        Considering these and other reasons, the BlackRock Fund Board unanimously concluded that, completion of the Reorganization is in the best interests of the BlackRock Fund and its shareholders and that the interests of the shareholders of the BlackRock Fund will not be diluted with respect to net asset value as a result of the Reorganization. The approval determination was made on the basis of each Trustee’s business judgment after consideration of all of the factors taken as a whole, though individual Trustees may have placed different weight on various factors and assigned different degrees of materiality to various factors.

        If the Reorganization is not approved by BlackRock Fund shareholders, the BlackRock Fund will continue to operate for the time being as a separate fund advised by BlackRock Advisors, and the BlackRock Fund Board will consider other alternatives.

         The BlackRock Fund Board unanimously recommends that you vote “For” the Reorganization.

Investment Objectives and Principal Investment Strategies

         Investment Objectives. The investment objective of the BlackRock Fund is to seek long-term capital appreciation, with current income as a secondary objective. The investment objective of the ML Fund is long-term capital growth. The BlackRock Fund’s investment objective may be changed by the BlackRock Fund Board without shareholder approval upon 30 days’ notice to shareholders. The ML Fund’s investment objective is a fundamental policy that may not be changed without approval of shareholders representing a majority of the ML Fund’s outstanding voting securities, as defined in the 1940 Act. The combined fund will pursue the ML Fund’s investment objective.

         Principal Investment Strategies. The BlackRock Fund invests primarily in equity securities of U.S. large capitalization companies. The BlackRock Fund, under normal circumstances, invests at least 80% of its net assets in equity securities issued by U.S. large capitalization value companies (defining “large capitalization” companies as those with market capitalizations equal to those within the universe of Russell 1000 ^® Value Index stocks). Using quantitative techniques and a multi-factor model, the BlackRock Fund’s management team identifies stocks with low relative valuations and improving earnings expectations when compared with their sector peers. The BlackRock Fund seeks to maintain the market capitalization, sector allocations and style characteristics of its portfolio so as to be similar to those of the Russell 1000 ^® Value Index. In seeking to maintain the optimal risk/return trade-off, the BlackRock Fund management team rebalances the portfolio regularly.

        The ML Fund invests primarily in a diversified portfolio of equity securities of large capitalization companies located in the United States. The ML Fund emphasizes value-oriented investments. Under normal circumstances, the ML Fund invests at least 80% of its net assets in equity securities of large capitalization companies selected from among those that are, at the time of purchase, included in the Russell 1000 ^® Value Index. For this purpose, net assets include any borrowings for investment purposes. The ML Fund invests primarily in equity securities that the investment adviser believes are selling at below-normal valuations. FAM uses a proprietary multi-factor quantitative model to look for companies within the Russell 1000 ^® Value Index that, in FAM’s opinion, are consistent with the investment objective of the ML Fund. Factors employed by the model include stock valuation, quality of earnings and potential future earnings growth. In seeking to outperform its benchmark, the Russell 1000 ^® Value Index, the ML Fund will allocate its common stock investments among industry sectors in a manner generally comparable to the sector weighting in the Russell 1000 ^® Value Index. The ML Fund may continue to hold a security after it has been removed from the Russell 1000 ^® Value Index.

        The combined fund’s principal investment strategies will be those of the ML Fund.

         Comparison. Because the BlackRock Fund and the ML Fund pursue similar investment objectives and hold similar securities, the proposed Reorganization is not expected to cause significant portfolio turnover or transaction expenses associated with the sale of securities held by the BlackRock Fund that are incompatible with the ML Fund’s investment objective.

        For information about the fundamental investment restrictions applicable to each Fund, see Appendix A.

Fees and Expenses

        Assuming shareholders of the BlackRock Fund approve the proposed Reorganization, substantially all the assets and certain stated liabilities of the BlackRock Fund will be combined with those of the ML Fund, an account will be set up in each BlackRock Fund shareholder’s name at the ML Fund and each such shareholder will receive shares of the ML Fund. After the Reorganization, BlackRock Fund shareholders will hold shares of

the same or a similar class of the ML Fund with an aggregate net asset value equal to the aggregate net asset value of BlackRock Fund shares owned immediately prior to the Reorganization.

        The BlackRock Fund currently offers five classes of shares (Investor A, B and C Shares, Institutional Shares and Service Shares). The ML Fund offers five classes of shares (Class A, B, C, I, and R Shares which will be renamed Investor A, Investor B, Investor C, Institutional and R Shares, respectively), and, in connection with the Reorganization, will issue an additional new class of Service Shares.

        If the Reorganization is approved and completed, holders of BlackRock Fund shares will receive ML Fund shares as follows:

Fee Table of the BlackRock Fund, the ML Fund and the
Pro Forma Combined Fund as of October 31, 2005 (unaudited)

        The following comparative tables describe the fees and expenses that you may incur for buying and holding shares of the BlackRock Fund versus shares of the ML Fund. The pro forma column shows the combined fund’s fees and expenses assuming that the Reorganization is approved by the shareholders of the BlackRock Fund. The tables are based on the expenses for the year ended October 31, 2005. Future fees and expenses may be greater or less than those indicated below.

EXAMPLES:

These examples assume that an investor invests $10,000 in the relevant Fund for the time periods indicated, that the investment has a 5% return each year, that the investor pays the sales charges, if any, that apply to the particular class and that the Fund’s operating expenses remain the same. These assumptions are not meant to indicate that the investor will receive a 5% annual rate of return. The annual return may be more or less than the 5% used in these examples. The class designations shown in parentheses are the class designations to be used after the Reorganization. Although actual costs may be higher or lower, based on these assumptions, an investor’s costs would be:

Federal Tax Consequences

        The Reorganization is expected to qualify as a tax-free “reorganization” for U.S. federal income tax purposes. If the Reorganization so qualifies, in general, neither the ML Fund, the BlackRock Fund, nor their respective shareholders, will recognize gain or loss for U.S. federal income tax purposes in the transactions contemplated by the Reorganization, and neither the ML Fund nor the Master Portfolio will recognize gain or loss on the transfer by the ML Fund to the Master Portfolio of assets in exchange for beneficial interests in the Master Portfolio. As a condition to the closing of the Reorganization, each of the ML Fund and the BlackRock Fund will receive an opinion from Sidley Austin LLP to that effect. No tax ruling from the Internal Revenue Service (“IRS”) regarding the Reorganization has been or will be requested. The opinion of counsel is not binding on the IRS or any court and thus does not preclude the IRS from asserting, or a court from rendering, a contrary position.

        If any of the portfolio assets of the BlackRock Fund are sold by the BlackRock Fund in connection with the Reorganization, the tax impact of such sales will depend on the difference between the price at which such portfolio assets are sold and the BlackRock Fund’s basis in such assets. Any gains will be distributed to the BlackRock Fund’s shareholders as either capital gain dividends (to the extent of long-term capital gains) or ordinary dividends (to the extent of short-term capital gains) during or with respect to the year of sale, and such distributions will be taxable to shareholders.

        At any time prior to the consummation of the Reorganization, a shareholder may redeem shares, likely resulting in recognition of gain or loss to such shareholder for U.S. federal and state income tax purposes. For more information about the U.S. federal income tax consequences of the Reorganization, see “Material U.S. Federal Income Tax Consequences of the Reorganization.”

Purchase, Exchange, Redemption and Valuation of Shares

        Procedures for the purchase, exchange, redemption and valuation of shares of the ML Fund and the BlackRock Fund are similar.

         Purchasing Shares. The class structure and purchase and distribution procedures for shares are substantially similar for both the BlackRock and the ML Fund. See “Comparison of the BlackRock Fund and the ML Fund — Purchase, Exchange, Redemption and Valuation of Shares — Purchasing Shares.” After the Reorganization, the combined fund will offer Investor A, Investor B, Investor C, Institutional, Service and R Shares. A shareholder holding shares of the BlackRock Fund or the ML Fund wishing to purchase additional shares of the combined fund after the Reorganization, may find that the fees and expenses on the share classes, though similarly named, may not be the same as such fees and expenses on the shares he or she held prior to the Reorganization. See “Fees and Expenses” above.

         Exchanging Shares. Shareholders of the ML Fund holding Class A, Class B, Class C and Class I shares have an exchange privilege with certain other funds advised by FAM and its affiliate, MLIM. Holders of Investor A, Investor B and Investor C Shares of the BlackRock Fund have an exchange privilege with certain funds advised by BlackRock Advisors. Shareholders of the combined fund (other than holders of Service and R Shares) will have an exchange privilege into the same or similarly designated shares of other funds in the complex of funds advised by BlackRock Advisors or its affiliates. In making such exchanges shareholders may be subject to different fees and expenses than their original shares. See “Comparison of the BlackRock Fund and the ML Fund — Purchase, Exchange, Redemption and Valuation of Shares — Exchanging Shares.”

         Redeeming Shares. The redemption procedures for shares of the ML Fund are substantially similar to the redemption procedures for shares of the BlackRock Fund. See “Comparison of the BlackRock Fund and the ML Fund — Purchase, Exchange, Redemption and Valuation of Shares — Redeeming Shares.”

         Valuation of Shares. The ML Fund calculates the net asset value of each class of its shares (generally by using market quotations) each day the New York Stock Exchange (the “NYSE”) is open as of the close of business on the NYSE based on prices at the time of closing. The NYSE generally closes at 4:00 p.m. Eastern time. The net asset value used in determining share price is the next one calculated after the purchase or redemption order is placed. See “Comparison of the BlackRock Fund and the ML Fund — Purchase, Exchange, Redemption and Valuation of Shares —Valuation of Shares.”

AND THE ML FUND

Principal and Other Investment Risks

        Because of their similar investment objectives and principal investment strategies, the BlackRock Fund and the ML Fund are subject to similar investment risks. The following discussion describes the principal and certain other risks that may affect the combined fund. You will find additional descriptions of specific risks in the BlackRock Fund Prospectus and the ML Fund Prospectus.

        There is no guarantee that shares of either Fund will not lose value. This means shareholders of either Fund and shareholders of the combined fund could lose money.

        The primary risks of investing in the Funds include market risk, selection risk, and investment style risk. Market risk is the risk that one or more markets in which a fund invests will go down in value, including the possibility that a market will go down sharply and unpredictably. Selection risk is the risk that the securities that a fund’s investment adviser selects will underperform the markets, the relevant indices or securities selected by other funds with similar investment objectives and investment strategies. Both Funds follow an investing style that favors value companies. The value investing style may over time go in and out of favor during certain market conditions. At times when the investing style used by a Fund is out of favor, either Fund may underperform other equity funds that use different investing styles.

        Depending on its investment policies, one or both Funds are subject to several types of secondary risk, including: (i) borrowing and leverage risk; (ii) risks related to securities lending; (iii) risks related to depositary receipts; (iv) the risk that various potential hedging strategies will reduce gains and (v) risks related to investments in when issued or delayed delivery securities and forward commitments.

Investment Objectives and Principal Investment Strategies

         BlackRock Fund. The BlackRock Fund’s investment objective is to seek long-term capital appreciation with current income as a secondary objective. The BlackRock Fund’s investment objectives may be changed by the BlackRock Fund Board without shareholder approval upon 30 days’ notice to shareholders.

        The BlackRock Fund invests primarily in equity securities of U.S. large capitalization companies. The BlackRock Fund, under normal circumstances, invests at least 80% of its net assets in equity securities issued by U.S. large capitalization value companies (generally defining “large capitalization” companies as those with market capitalizations equal to those within the universe of Russell 1000 ^® Value Index stocks). The BlackRock Fund’s management team uses quantitative techniques to analyze a universe of approximately 800 value companies. The management team uses a multi-factor model, which identifies the key factors that drive the performance of value stocks. Using this multi-factor model, the BlackRock Fund’s management team identifies stocks with low relative valuations and improving earnings expectations when compared with their sector peers. Based on this information, and using sophisticated risk measurement tools, the management team selects stocks, together with their appropriate weightings, that it believes will maximize the BlackRock Fund’s return per unit of risk. The BlackRock Fund seeks to maintain the market capitalization, sector allocations and style characteristics of the Fund’s portfolio so as to be similar to those of the Russell 1000 ^® Value Index. In order to remain fully invested and instead of purchasing and selling securities directly, the BlackRock Fund may also invest in depositary receipts that seek to replicate the price performance and dividend yield of the Russell 1000 ^® Value Index. In extreme market conditions, the BlackRock Fund temporarily may invest some or all of its assets in high quality money market securities for the purpose of avoiding market losses. In seeking to maintain the optimal risk/return trade-off, the BlackRock Fund management team rebalances the portfolio regularly.

        The BlackRock Fund management team may, when consistent with the Fund’s investment goal, buy or sell options or futures on a security or an index of securities (commonly known as derivatives).

         ML Fund. The investment objective of the ML Fund is long-term capital growth. The ML Fund’s investment objective is a fundamental policy that may not be changed without approval of shareholders representing a majority of the ML Fund’s outstanding voting securities, as defined in the 1940 Act.

        The ML Fund invests primarily in a diversified portfolio of equity securities of large capitalization companies located in the United States. Under normal circumstances, the ML Fund invests at least 80% of its net assets in equity securities of large capitalization companies selected from among those that are, at the time of purchase, included in the Russell 1000 ^® Value Index.

        The ML Fund seeks to outperform the Russell 1000 ^® Value Index by investing in equity securities that the ML Fund’s investment adviser believes are selling at below normal valuations. In selecting securities for the ML Fund’s portfolio from it’s benchmark universe, the ML Fund’s investment adviser uses a proprietary multi-factor quantitative model. The factors employed by the model include stock valuation, quality of earnings and potential future earnings growth.

        Because the ML Fund generally will not hold all the stocks in its applicable index, and because the ML Fund’s investments may be allocated in amounts that vary from the proportional weightings of the various stocks in that index, the ML Fund is not an “index” fund. In seeking to outperform the relevant benchmark, however, the ML Fund’s investment adviser reviews potential investments using certain criteria that are based on the securities in the relevant index. These criteria currently include the following:
 

        In addition to the main strategies discussed above, the ML Fund may use certain other investment strategies. The ML Fund also may invest in securities of foreign issuers that are represented by American Depositary Receipts, or “ADRs” and the ML Fund may also lend its portfolio securities and invest uninvested cash balances in affiliated money market funds. The ML Fund may invest in investment grade convertible securities, preferred stock, illiquid securities, and U.S. Government debt securities ( i.e. , securities that are direct obligations of the U.S. Government) and there are no restrictions on the maturity of the debt securities in which the ML Fund may invest.

        The ML Fund is organized in a “master/feeder” structure and is a feeder fund that invests all of its assets in the Master Portfolio of the Master Trust, which has the same investment objective and strategies as the ML Fund. All investments will be made at the level of the Master Portfolio and investment advisory arrangements are made at the Master Trust level. Therefore, the ML Fund’s investment results will correspond directly to the investment results of the Master Portfolio. In the Reorganization, the assets acquired by the ML Fund from the BlackRock Fund will be contributed to the Master Portfolio in exchange for interests in the Master Portfolio.

        The ML Fund may use derivatives to hedge its investments.

         Combined Fund. The combined fund’s investment objective and principal investment strategies will be those of the ML Fund. Because the BlackRock Fund and the ML Fund pursue similar investment objectives and hold similar securities, the proposed Reorganization is not expected to cause significant portfolio turnover or transaction expenses associated with the sale of securities held by the BlackRock Fund which are incompatible with the ML Fund’s investment objective. It is expected that the combined fund will change its name and ultimately be renamed the BlackRock Large Cap Value Fund.

Performance Information

        The following tables provide performance information for the currently existing shares of each class of the ML Fund and the BlackRock Fund, including and excluding maximum applicable sales charges, for the periods indicated. Past performance is not predictive of future performance. Since the ML Fund’s Service Shares to be issued in the Reorganization are newly created, no ML Fund performance information is provided for those shares. For more information concerning the performance of the ML Fund, please refer to the ML Fund Prospectus and the ML Fund Annual Report, both of which accompany the Combined Prospectus/Proxy Statement and the ML Fund SAI which is available upon request. For more information concerning the performance of the BlackRock Fund, please refer to the BlackRock Fund Prospectus, the BlackRock Fund SAI and the 2005 Annual Report to Shareholders of the BlackRock Fund which are available upon request. See the cover page of this Combined Prospectus/Proxy Statement for information about how to obtain copies of various documents.

        It is expected that the combined fund will be renamed the BlackRock Large Cap Value Fund following the Reorganization. Because the combined fund will most closely resemble the ML Fund, the ML Fund will be the accounting survivor of the Reorganization. As such, the combined fund will assume the performance history of the ML Fund at the closing of the Reorganization.

Management of the Funds

         BlackRock Fund. BlackRock Advisors, located at 100 Bellevue Parkway, Wilmington, Delaware 19809, serves as the investment adviser to the BlackRock Fund. BlackRock Advisors is a wholly-owned subsidiary of BlackRock, which is currently a majority-owned, indirect subsidiary of PNC.

        The new asset management company formed in connection with the transaction between MLIM and BlackRock will operate under the BlackRock name and be governed by a board of directors with a majority of independent members. Merrill Lynch will hold no more than a 49.8% economic stake and a 45% voting interest in the new company, and the common stock interest of BlackRock’s current majority shareholder, The PNC Financial Services Group, Inc. (“PNC”), will be diluted to about 34%. Each of Merrill Lynch and PNC has agreed that it will vote all of its shares in accordance with the recommendation of the new company’s board of directors on all matters, including election of directors.

         The BlackRock Fund’s management team is led by Fred Herrmann, CFA, and David Byrket, CFA, both Managing Directors at BlackRock Advisors. Mr. Herrmann and Mr. Byrket head a six person investment team at BlackRock Advisors focused on quantitative strategies for the equity market. They have been managing the BlackRock Fund since March 2003. Prior to joining BlackRock Advisors in 2003, both Mr. Byrket and Mr. Herrmann were Managing Directors at Weiss, Peck and Greer, LLC since 2001. They have been responsible for managing quantitative portfolios since 1996.

       The BlackRock Fund SAI provides additional information about the compensation of the BlackRock Fund’s portfolio managers, other accounts managed by such portfolio managers, and such portfolio managers’ ownership of securities in the BlackRock Fund.

         ML Fund. FAM, located at 800 Scudders Mill Road, Plainsboro, New Jersey 08536, serves as the investment adviser to the Master Trust and manages the Master Portfolio’s investments subject to the oversight of the Master Trust Board. FAM has the responsibility for making all investment decisions for the Master Portfolio. FAM is an affiliate of MLIM, which is an indirect, wholly-owned subsidiary of Merrill Lynch.

        Robert C. Doll, Jr., is the ML Fund’s senior portfolio manager and is primarily responsible for the day-to-day management of the ML Fund’s portfolio and the selection of its investments. He has been the ML Fund’s portfolio manager since inception. Mr. Doll has been President of FAM and its affiliate, MLIM, since 2001. He was Co-Head (Americas Region) of MLIM from 1999 to 2000. Prior to joining MLIM, he was Chief Investment Officer of OppenheimerFunds, Inc. in 1999 and Executive Vice President thereof from 1991 to 1999. He has been President and a member of the Board of each of the funds advised by MLIM and its affiliates since 2005.

        The ML Fund SAI provides additional information about the compensation of the ML Fund’s portfolio manager, other accounts managed by such portfolio manager, and such portfolio manager’s ownership of securities in the ML Fund.

         Combined Fund . As discussed below under “Investment Advisory Agreements — ML Fund,” following the Reorganization, BlackRock Advisors will serve as investment adviser to the combined fund. The combined fund’s management team will be led by Robert C. Doll, Jr.

Investment Advisory Agreements

         BlackRock Fund. BlackRock Advisors provides investment advisory services to the BlackRock Fund pursuant to an investment advisory agreement. The investment advisory agreement between the BlackRock Fund and BlackRock Advisors is referred to herein as the “BlackRock Advisory Agreement.”

        BlackRock Advisors is entitled to fees computed daily and payable monthly. The maximum annual advisory fees that can be paid to BlackRock Advisors (as a percentage of average daily net assets of the BlackRock Fund) are as follows:

Applying this fee schedule, the BlackRock Fund’s effective advisory fee rate was 0.550% of the BlackRock Fund’s average daily net assets for the twelve month period ended October 31, 2005.

        BlackRock Advisors has contractually agreed until February 1, 2007 to waive or reimburse fees or expenses in order to limit expenses (excluding interest, taxes, brokerage commissions, and other expenditures which are capitalized in accordance with generally accepted accounting principles and other extraordinary expenses not

incurred in the ordinary course of business, if any) as a percentage of average daily net assets allocated to each class as follows: 1.25% (for Investor A Shares), 2.00% (for Investor B and C Shares), 0.79% (for Institutional Shares), and 1.09% (for Service Shares). See “Summary — Fees and Expenses” above.

        To maintain this limit, BlackRock Advisors and the BlackRock Fund have entered into an expense limitation agreement. The agreement sets a limit on certain of the operating expenses through February 1, 2007 and requires BlackRock Advisors to waive or reimburse fees or expenses if these operating expenses exceed that limit.

        A discussion regarding the basis for the BlackRock Fund Board’s approval of the BlackRock Advisory Agreement is available in the BlackRock Fund’s most recent semi-annual report to shareholders for the period ended March 31, 2006, and is available to shareholders by calling 1-800-441-7762.

         ML Fund. The ML Fund invests all of its assets in the Master Portfolio of the Master Trust. Accordingly, the ML Fund does not invest directly in portfolio securities and does not require investment advisory services. All portfolio management occurs at the Master Trust level. The Master Trust, on behalf of the Master Portfolio, has entered into an investment advisory agreement with FAM, as investment adviser (the “ML Advisory Agreement”). Currently, FAM has overall responsibility for managing the investments of the Master Portfolio, subject to the oversight of the Master Trust Board. Under the ML Advisory Agreement, FAM provides the Master Trust with investment advisory and management services. FAM is responsible for the actual management of the Master Portfolio’s portfolio and reviews the Master Portfolio’s holdings in light of its own research analysis and that from other relevant sources. The responsibility for making decisions to buy, sell or hold a particular security rests with FAM. FAM receives for its services to the Master Portfolio monthly compensation at the annual rate of 0.50% of the average daily net assets of the Master Portfolio. FAM has voluntarily agreed to breakpoints in the advisory fee schedule for net assets in excess of $3 billion as discussed below in connection with the BlackRock Advisors investment advisory agreement. FAM performs certain of the other administrative services and provides all the office space, facilities, equipment and necessary personnel for management of the Master Trust.

        FAM has a sub-advisory agreement with Merrill Lynch Asset Management U.K. Limited, an affiliate, under which FAM may pay a fee for services it receives.

        A discussion regarding the basis for the Master Trust Board’s approval of the ML Advisory Agreement is available in the ML Fund’s annual report to shareholders for the fiscal year ended October 31, 2005, and is available to shareholders by calling 1-800-995-6526.

        In connection with the transaction between MLIM and BlackRock, BlackRock Advisors will enter into an investment advisory agreement (the “New Investment Advisory Agreement”) with the Master Trust on behalf of the Master Portfolio, subject to approval by the ML Fund Board, the Master Trust Board and the ML Fund’s shareholders. Pursuant to the New Investment Advisory Agreement, the Master Trust, on behalf of the Master Portfolio, will pay BlackRock Advisors monthly compensation at the annual rate of 0.50% of that portion of average daily net assets not exceeding $3 billion, and 0.45% of that portion of average daily net assets exceeding $3 billion. The services provided by BlackRock Advisors and its affiliates under the New Investment Advisory Agreement are substantially similar in all material respects as the services provided by FAM under the ML Advisory Agreement for the Master Trust.

        The New Investment Advisory Agreement generally will provide that, subject to the direction and control of the ML Fund Board, BlackRock Advisors will (a) act as investment adviser for and supervise and manage the investment and reinvestment of the Master Portfolio’s assets with complete discretion in purchasing and selling securities and other assets for the Master Portfolio and in voting, exercising consents and exercising all other rights pertaining to such securities and other assets on behalf of the Master Portfolio, (b) supervise continuously the investment objectives and policies of the Master Portfolio and the composition of its investment portfolio, (c) subject to the restrictions of the ML Fund’s organizational documents, the provisions of the 1940 Act and the Investment Advisers Act of 1940, as amended (the “Advisers Act”), the ML Fund’s investment objectives and policies, the applicable rules and regulations of the SEC, and other applicable federal and state law, as well as any specific policies and determinations of the ML Fund Board and Master Trust Board disclosed to BlackRock Advisors, arrange for the purchase and sale of securities and other assets held in the investment portfolio of the Master Portfolio; and (d) provide investment research to the Master Trust.

        The New Investment Advisory Agreement provides that BlackRock Advisors may to the extent permitted by applicable law appoint one or more sub-advisers, including affiliates of BlackRock Advisors, to perform investment advisory services with respect to the ML Fund. It is anticipated that pursuant to this provision, and in compliance with SEC rules and interpretations, BlackRock Advisors may appoint one or more affiliates to act as sub-adviser to the ML Fund.

         Combined Fund. If the shareholders of the BlackRock Fund approve the Reorganization, the combined fund will be managed by BlackRock Advisors pursuant to the New Investment Advisory Agreement, the major elements of which are described above.

        BlackRock Advisors will perform a similar investment advisory role for the Master Portfolio under the terms of the New Investment Advisory Agreement as it does for the BlackRock Fund under the terms of the BlackRock Advisory Agreement. Following the Reorganization, the ML Fund fee structure will apply. It is anticipated that at the time of the Reorganization the change to the ML Fund fee structure will result in the combined fund having lower contractual advisory fees than under the BlackRock Fund Advisory Agreement.

Administration Agreements

         BlackRock Fund. BlackRock Advisors and PFPC Inc. (“PFPC”) serve as the BlackRock Fund’s co-administrators pursuant to an administration agreement (the “BlackRock Administration Agreement”). PFPC maintains office facilities for the BlackRock Fund and furnishes the BlackRock Fund with statistical and research data, clerical, accounting, bookkeeping and other administrative services. Under the BlackRock Administration Agreement, BlackRock Advisors is responsible for: (i) the supervision and coordination of the performance of the BlackRock Fund’s service providers; (ii) the negotiation of service contracts and arrangements between the BlackRock Fund and its service providers; (iii) acting as liaison between the trustees of the BlackRock Fund and the BlackRock Fund’s service providers in connection with the BlackRock Fund’s operations and (iv) providing ongoing business managerial and support services.

        Under the BlackRock Administration Agreement, the BlackRock Fund pays BlackRock Advisors and PFPC a fee, computed daily and payable monthly, at an aggregate annual rate of (i) 0.075% of the first $500 million of the BlackRock Fund’s average daily net assets, 0.065% of the next $500 million of the BlackRock Fund’s average daily net assets and 0.055% of the BlackRock Fund’s average daily net assets in excess of $1 billion; and (ii) 0.025% of the first $500 million of the average daily net assets allocated to each class of shares of the BlackRock Fund, 0.015% of the next $500 million of the average daily net assets allocated to each class of shares of the BlackRock Fund and 0.005% of the average daily net assets allocated to each class of shares of the BlackRock Fund in excess of $1 billion. Applying this fee schedule, the BlackRock Fund’s effective administrative fee rate was 0.10% of the BlackRock Fund’s average daily net assets for the twelve month period ended October 31, 2005. BlackRock Advisors and PFPC may from time to time voluntarily waive administration fees with respect to the BlackRock Fund and may voluntarily reimburse the BlackRock Fund for expenses.

         ML Fund. FAM provides administrative services to the ML Fund pursuant to an administration agreement between FAM and ML Series (the “ML Administration Agreement”). Under the ML Administration Agreement, FAM provides certain administrative services to the ML Fund and provides (or causes its affiliates to provide) for the ML Fund’s office space, facilities and necessary personnel as well as the fees of those Directors and officers of ML Series who are affiliated persons of FAM or any of its affiliates. Under the ML Administration Agreement, FAM receives for its services to ML Series and the ML Fund monthly compensation at the annual rate of 0.25% of the average daily net assets of the ML Fund. In connection with this combination of MLIM and BlackRock, BlackRock Advisors will enter into an administration agreement (the “New Administration Agreement”) with ML Series, on behalf of the ML Fund. Pursuant to the New Administration Agreement, the ML Fund will pay BlackRock Advisors the same fee rate provided under the ML Administration Agreement. The services provided by BlackRock Advisors and its affiliates under the New Administration Agreement will be substantially similar in all material respects to the services provided by FAM under the ML Administration Agreement.

         Combined Fund. Following the Reorganization, BlackRock Advisors will provide the combined fund with administrative services pursuant to the New Administration Agreement, the major elements of which are described above under “ML Fund.” Although the combined fund’s fee for administration services will be higher than the fee paid under the BlackRock Administration Agreement, this is partially offset by the lower contractual advisory fee for the combined fund under the New Investment Advisory Agreement.

Other Service Providers

         BlackRock Fund. PFPC, located at 301 Bellevue Parkway, Wilmington, Delaware 19809, serves as the co-administrator, transfer agent and dividend disbursing agent for the BlackRock Fund.

         Combined Fund. Immediately following the Reorganization, the ML Fund’s service providers, other than the transfer agent, are expected to service the combined fund. PFPC, the BlackRock Fund’s transfer agent, is expected to serve as the transfer agent for the combined fund. The combined fund will continue to be distributed by FAM Distributors, as a co-distributor, along with the addition of BlackRock Distributors as a co-distributor. Any changes in service providers thereafter are not expected to affect the nature or quality of services provided to the Fund or its shareholders.

Distribution and Service Fees

         BlackRock Fund. The BlackRock Fund has adopted a plan (the “BlackRock Fund Distribution Plan”) that allows the BlackRock Fund to pay distribution fees for the sale of its shares pursuant to Rule 12b-1 under the 1940 Act and shareholder servicing fees for certain services provided to its shareholders.

        Under the BlackRock Fund Distribution Plan, Investor Shares pay a fee (a distribution fee) to BlackRock Distributors and/or affiliates of PNC (including BlackRock Advisors) for distribution and sales support services. The distribution fees may also be used to pay affiliated and unaffiliated brokers, dealers, financial institutions and industry professionals (including BlackRock Advisors, PNC Bank and its affiliates) (“Service Organizations”) for sales support services and related expenses. All Investor B and Investor C Shares pay a maximum distribution fee of 0.75% per year. All Investor A Shares currently may pay a maximum distribution fee of 0.10% per year, however, such fee is currently being waived by the BlackRock Fund, and, upon the closing of the Reorganization, Investor A Shares of the combined fund will not be subject to distribution fees.

        Under the BlackRock Fund Distribution Plan, the BlackRock Fund also pays shareholder servicing fees to Service Organizations whereby the Service Organizations provide support services to their customers who own Investor and Service Shares in return for these fees. The BlackRock Fund may pay a shareholder servicing fee of up to 0.25% per year of the average daily net asset value of Investor A, Investor B, Investor C and Service Shares of the BlackRock Fund. Institutional Shares do not pay distribution or shareholder servicing fees.

         ML Fund. The ML Fund has adopted plans of distribution pursuant to Rule 12b-1 under the 1940 Act (the “ML Fund Distribution Plans”). Under the ML Fund Distribution Plans, the ML Fund pays annual service and distribution fees to FAM Distributors at a rate of up to 0.25% of average daily net assets for Class A Shares and 1.0% of average daily net assets for Class B Shares and Class C Shares. These fees are used to cover the costs of the Fund’s marketing and distribution efforts, such as compensating financial advisers and other financial intermediaries. Class I Shares do not have distribution or service fees. In connection with the Reorganization, the ML Fund will adopt a form of Distribution Plan substantially similar to the ML Fund Distribution Plans with respect to its newly-created Service Shares, pursuant to which the ML Fund will pay annual service fees at a rate up to 0.25% of average daily net assets for Service Shares.

         Combined Fund. Following the Reorganization, the combined fund will use the ML Fund Distribution Plans, as described above, for its currently existing share classes and will adopt a similar form of Distribution Plan for its newly-created Service Shares providing for distribution and service fees as described above.

        For more information on the ML Fund Distribution Plans or the BlackRock Fund Distribution Plan, including a complete list of services provided thereunder, see the ML Fund Prospectus (a copy of which accompanies this Combined Prospectus/Proxy Statement) and the BlackRock Fund Prospectus, respectively.

Purchase, Exchange, Redemption and Valuation of Shares

        Procedures for the purchase, exchange, redemption and valuation of shares of the ML Fund and the BlackRock Fund are similar. Shareholders should refer to the ML Fund Prospectus (a copy of which accompanies this Combined Prospectus/Proxy Statement) and the BlackRock Fund Prospectus for the specific procedures applicable to purchases, exchanges and redemptions of shares. In addition to the policies described below, certain fees may be assessed in connection with the purchase, exchange and redemption of shares. See “Summary — Fees and Expenses” above. The following discussion describes the policies and procedures related to the purchase, exchange, redemption and valuation of shares of the ML Fund, which policies and procedures will be used by the combined fund.

         Purchasing Shares. The class structure and purchase and distribution procedures for shares are substantially similar for both the BlackRock Fund and the ML Fund. The ML Fund currently offers five classes of shares of common stock. The BlackRock Fund currently offers five classes of shares of beneficial interest. The ML Fund’s Class A Shares are similar to the BlackRock Fund’s Investor A Shares, the ML Fund’s Class B Shares are similar to the BlackRock Fund’s Investor B Shares, the ML Fund’s Class C Shares are similar to the BlackRock Fund’s Investor C Shares and the ML Fund’s Class I Shares are similar to the BlackRock Fund’s Institutional Shares. The BlackRock Fund also issues Service Shares, which are not subject to sales charges or distribution fees, but are subject to service fees. For a complete discussion of the classes of shares and the purchase and distribution procedures related thereto for the ML Fund, see “Your Account — Pricing of Shares,” “— How to Buy, Sell, Transfer and Exchange Shares” and “— Participation in Fee-Based Programs” in the ML Fund Prospectus and, for the BlackRock Fund, see “About Your Investment — How to Buy/Sell Shares” in the BlackRock Fund Prospectus.

         Exchanging Shares. Shareholders can exchange Class A, Class B, Class C and Class I Shares of the ML Fund for shares of certain other funds advised by MLIM or its affiliates (“MLIM/FAM-advised funds”). The shareholder must have held the shares used in the exchange for at least 15 calendar days before he or she can exchange to another fund. Class A, Class B, Class C and Class I Shares are generally exchangeable for shares of the same class of another MLIM/FAM-advised fund. If a shareholder owns Class I Shares and wishes to exchange into a fund in which he or she has no Class I Shares (and is not eligible to purchase Class I Shares), the shareholder will exchange into Class A Shares. Some of the MLIM/FAM-advised funds impose a different initial or deferred sales charge schedule. If a shareholder exchanges Class A or Class I Shares for shares of a fund with a higher initial sales charge than the shareholder originally paid, the shareholder will be charged the difference at the time of exchange. If a shareholder exchanges Class B Shares for shares of a fund with a different deferred sales charge schedule, the higher schedule will apply. The time the shareholder holds Class B or Class C Shares in both funds will count when determining his or her holding period for calculating a deferred sales charge at redemption. If a shareholder exchanges Class A or Class I Shares for money market fund shares, he or she will receive Class A Shares of Summit Cash Reserves Fund. Class B or Class C Shares of the ML Fund will be exchanged for Class B Shares of Summit Cash Reserves Fund.

        Holders of Investor A, Investor B and Investor C Shares of the BlackRock Fund may exchange their shares for shares of the same class of another BlackRock Fund. Shareholders may make an exchange by sending a written request to the BlackRock Fund or telephoning the BlackRock Fund once an account is set up unless a shareholder previously indicated that he or she did not want this option. Holders of Institutional and Service Shares of the BlackRock Fund do not have an exchange privilege.

        Following the Reorganization, BlackRock Fund shareholders who receive Investor A, Investor B, Investor C or Institutional Shares of the ML Fund will have the right to exchange such shares for Investor A or Class A, Investor B or Class B, Investor C or Class C, or Institutional or Class I Shares, respectively, of another fund advised by BlackRock Advisors or its affiliates, using the same procedures currently applicable to the ML Fund, as described above. In making such exchanges, shareholders may be subject to different fees and expenses than with their original shares. For purposes of computing the CDSC that may be payable upon a disposition of the shares acquired in the exchange, the holding period for the previously owned shares of the BlackRock Fund will be “tacked” to the holding period of the newly acquired shares of the other fund.

         Redeeming Shares. The redemption procedures for shares of the ML Fund are substantially similar to the redemption procedures for shares of the BlackRock Fund. See “Your Account — Pricing of Shares,” “— How to Buy, Sell, Transfer and Exchange Shares” and “— Participation in Fee-Based Programs” in the ML Fund Prospectus and “About Your Investment — How to Buy/Sell Shares” in the BlackRock Fund Prospectus.

         Valuation of Shares . The ML Fund and the BlackRock Fund have similar procedures for valuing securities. Each Fund computes its net asset value (“NAV”) by using prices as of the close of trading on the NYSE and valuing portfolio securities (i) for which market quotations are readily available at such market quotations (for example, using the last reported sale price for securities listed on a securities exchange or using the mean between the last reported bid and asked prices on unlisted securities) and (ii) for which market quotations are not readily available and any other assets at their fair value as determined in good faith in accordance with procedures established by such Fund’s Board of Trustees. In cases where a security is traded on more than one exchange, the security is valued on the exchange designated as the primary market. Securities with remaining maturities of 60 days or less are valued at amortized cost, which approximates market value.

        Each Fund calculates net asset value per share, and therefore effects sales, redemptions and exchanges of its shares, as of the close of trading on the NYSE each day the NYSE is open for trading.

        The ML Fund invests primarily in the securities of U.S. issuers or in ADRs of foreign issuers that trade in the U.S. markets. Therefore, the ML Fund generally prices its securities as of the close of the NYSE based on the closing market prices of the securities. However, if market quotations are not readily available or, in the investment adviser’s judgment, do not accurately reflect fair value for a security, that security may be valued by another method that the ML Fund Board believes more accurately reflects the fair value.

      These policies will apply to the combined fund following the Reorganization. There is no guarantee that both Funds will use the same price on a particular security at any given time.

Market Timing

        Each Fund discourages and does not accommodate frequent purchases and redemptions of shares by Fund shareholders, and each Fund’s Board has adopted policies and procedures to deter such frequent purchases and redemptions. For further information with respect to the ML Fund’s or the BlackRock Fund’s policies with respect to market timing, see the ML Fund Prospectus (a copy of which accompanies this Combined Prospectus/Proxy Statement) or the BlackRock Fund Prospectus.

FINANCIAL HIGHLIGHTS

        Financial highlights tables for the existing share classes of the ML Fund may be found in the ML Fund’s Prospectus, a copy of which accompanies this Combined Prospectus/Proxy Statement. Financial highlights tables for the share classes of the BlackRock Fund may be found in the BlackRock Fund Prospectus, which is available by calling 1-800-441-7762.

INFORMATION ABOUT THE REORGANIZATION

General

        Under the Reorganization Agreement, the BlackRock Fund will transfer substantially all of its assets and certain stated liabilities to the ML Fund in exchange for Investor A, Investor B, Investor C, Institutional and Service Shares of the ML Fund. For more details about the Reorganization Agreement, see Appendix B—“Form of Agreement and Plan of Reorganization.” The shares of the ML Fund issued to the BlackRock Fund will have an aggregate net asset value equal to the aggregate net asset value of the BlackRock Fund shares outstanding immediately prior to the Reorganization. Upon receipt by the BlackRock Fund of the shares of the ML Fund, the BlackRock Fund will distribute the shares to BlackRock Fund shareholders. Then, as soon as practicable after the date of the closing of the Reorganization (the “Closing Date”) the BlackRock Fund will be terminated as a series of BlackRock Funds under applicable state law.

        The distribution of ML Fund shares to BlackRock Fund shareholders will be accomplished by opening new accounts on the books of the ML Fund in the names of the BlackRock Fund shareholders and transferring to those shareholder accounts the shares of the ML Fund. Such newly-opened accounts on the books of the ML Fund will represent the respective pro rata number of shares of the same or a similar class of the ML Fund that the BlackRock Fund receives under the terms of the Reorganization Agreement. See “Terms of the Reorganization Agreement” below.

        Accordingly, as a result of the Reorganization, each BlackRock Fund shareholder will own the same or a similar class of shares of the ML Fund having an aggregate net asset value immediately after the Closing Date equal to the aggregate net asset value of that shareholder’s BlackRock Fund shares immediately prior to the Closing Date. The Reorganization will not result in dilution of either Fund’s net asset value. However, as a result of the Reorganization, a shareholder of either the ML Fund or the BlackRock Fund will hold a reduced percentage of ownership in the larger combined fund than the shareholder did in either of the separate Funds.

        No sales charge or fee of any kind will be assessed to the BlackRock Fund shareholders in connection with their receipt of shares of the ML Fund in the Reorganization, although shareholders who receive Investor B or Investor C shares of the ML Fund (and, under certain circumstances, Investor A shares) in the Reorganization will continue to be subject to a contingent deferred sales charge if they sell such shares after the Reorganization but before the applicable holding period expires. The holding period with respect to any contingent deferred sales charge applicable to shares of the ML Fund acquired in the Reorganization will be measured from the earlier of the time (i) the shares were purchased from the BlackRock Fund or (ii) shares were purchased from any other BlackRock fund and subsequently were exchanged for shares of the BlackRock Fund. Redemptions made after the Reorganization may be subject to contingent deferred sales charges and/or redemption fees.

Terms of the Reorganization Agreement

        Pursuant to the Reorganization Agreement, the ML Fund will acquire substantially all of the assets and certain stated liabilities of the BlackRock Fund on the Closing Date in consideration for shares of the ML Fund.

        On the Closing Date, the BlackRock Fund will transfer to the ML Fund substantially all of its assets in exchange solely for Investor A, Investor B, Investor C, Institutional and Service Shares of the ML Fund that are in the aggregate equal in value to the value of the assets of the BlackRock Fund transferred to the ML Fund as of the Closing Date, as determined in accordance with the ML Fund’s valuation procedures or such other valuation procedures as shall be mutually agreed upon by the parties, reduced by the value of certain stated liabilities of the BlackRock Fund provided for in an agreed upon schedule prior to the Closing Date that are assumed by the ML Fund. In order to minimize any potential for undesirable federal income and excise tax consequences in connection with the Reorganization, the BlackRock Fund will distribute on or before the Closing Date all of its undistributed net investment income and net capital gains as of such date.

        The BlackRock Fund expects to distribute the shares of the ML Fund to the shareholders of the BlackRock Fund promptly after the Closing Date. Thereafter, the BlackRock Fund will be terminated as a series of BlackRock Funds under Massachusetts law.

        The BlackRock Fund and the ML Fund have made certain standard representations and warranties to each other regarding capitalization, status and conduct of business.

        Unless waived in accordance with the Reorganization Agreement, the obligations of the parties to the Reorganization Agreement are conditioned upon, among other things:

        The Reorganization Agreement may be terminated or amended by the mutual consent of the parties either before or after approval thereof by the shareholders of the BlackRock Fund.

        The BlackRock Fund Board recommends that you vote to approve the Reorganization, as it believes the Reorganization is in the best interests of BlackRock Fund and its shareholders (as described more fully in “Reasons for the Reorganization” below) and that the interests of existing shareholders of the BlackRock Fund will not be diluted with respect to net asset value as a result of consummation of the proposed Reorganization.

Reasons for the Reorganization

        The factors considered by the BlackRock Fund Board with regard to the Reorganization include, but are not limited to, the following:

        Considering these and other reasons, the BlackRock Fund Board unanimously concluded that consummation of the Reorganization is in the best interests of the BlackRock Fund and its shareholders and that the interests of the shareholders of the BlackRock Fund will not be diluted with respect to net asset value as a result of the Reorganization. The approval determination was made on the basis of each Trustee’s business judgment after consideration of all of the factors taken as a whole, though individual Trustees may have placed different weight on various factors and assigned different degrees of materiality to various factors.

Material U.S. Federal Income Tax Consequences of the Reorganization

        The following is a general summary of the material anticipated U.S. federal income tax consequences of the Reorganization. The discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations, court decisions, published positions of the IRS and other applicable authorities, all as in effect on the date hereof and all of which are subject to change or differing interpretations (possibly with retroactive effect). The discussion is limited to U.S. persons who hold shares of the BlackRock Fund as capital assets for U.S. federal income tax purposes. This summary does not address all of the U.S. federal income tax consequences that may be relevant to a particular shareholder or to shareholders who may be subject to special treatment under federal income tax laws. No ruling has been or will be obtained from the IRS regarding any matter relating to the Reorganization. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax aspects described below. Shareholders must consult their own tax advisers as to the U.S. federal income tax consequences of the Reorganization, as well as the effects of state, local and non-U.S. tax laws.

        It is a condition to closing the Reorganization that each of the ML Fund and the BlackRock Fund receives an opinion from Sidley Austin LLP , counsel to the ML Fund, dated as of the Closing Date, that the Reorganization will be a “reorganization” within the meaning of Section 368(a) of the Code and that the BlackRock Fund and the ML Fund each will be a “party to a reorganization” within the meaning of Section 368(b) of the Code. As such a reorganization, the U.S. federal income tax consequences of the Reorganization can be summarized as follows:

        The opinion of Sidley Austin LLP will be based on U.S. federal income tax law in effect on the Closing Date. In rendering its opinion, Sidley Austin LLP will also rely upon certain representations of the management of the ML Fund and the BlackRock Fund and assume, among other things, that the Reorganization will be consummated in accordance with the operative documents. An opinion of counsel is not binding on the IRS or any court.

        The ML Fund intends to continue to be taxed under the rules applicable to regulated investment companies as defined in Section 851 of the Code, which are the same rules currently applicable to the BlackRock Fund and its shareholders.

        Prior to the Closing Date, the BlackRock Fund will declare a distribution to its shareholders, which together with all previous distributions, will have the effect of distributing to its shareholders all of its investment company taxable income (computed without regard to the deduction for dividends paid) and net realized capital gains, if any, through the Closing Date.

        A portion of the portfolio assets of the BlackRock Fund may be sold in connection with the Reorganization. The tax impact of such sales will depend on the difference between the price at which such portfolio assets are sold and the BlackRock Fund’s basis in such assets. Any capital gains recognized in these sales on a net basis will be distributed to the BlackRock Fund’s shareholders as capital gain dividends (to the extent of net realized long-term capital gains) and/or ordinary dividends (to the extent of net realized short-term capital gains) during or with respect to the year of sale, and such distributions will be taxable to shareholders.

        The ML Fund will succeed to the capital loss carryforwards of the BlackRock Fund, which will be subject to the limitations described below. The BlackRock Fund has capital loss carryforwards that, in the absence of the Reorganization, would generally be available to offset its capital gains. As a result of the Reorganization, however, the BlackRock Fund will undergo an “ownership change” for tax purposes (because the BlackRock Fund is significantly smaller than the ML Fund), and accordingly, the ML Fund’s use of the BlackRock Fund’s capital loss carryforwards will be limited by the operation of the tax loss limitation rules of the Code. The Code generally limits the amount of pre-ownership change losses that may be used to offset post-ownership change gains to a specific annual loss limitation amount (generally the product of the net asset value of the

BlackRock Fund immediately prior to the ownership change and a rate established by the IRS for the month of the Closing Date (for example, such rate is 4.30% for May, 2006)). Subject to certain limitations, any unused portion of these losses may be available in subsequent years, subject to the overall eight-year capital loss carryforward limit, as measured from the date of recognition. In addition, for five years after the Closing Date of the Reorganization, the combined fund will not be allowed to offset certain pre-Reorganization built-in gains attributable to one Fund, if any, with capital loss carryforwards attributable to the other Fund.

        Shareholders of the BlackRock Fund may redeem their shares or exchange their shares for shares of certain other funds distributed by BlackRock Distributors at any time prior to the closing of the Reorganization. Redemptions and exchanges of shares generally are taxable transactions, unless the shareholder’s account is not subject to taxation, such as an individual retirement account or other tax-qualified retirement plan. Shareholders should consult with their own tax advisers regarding potential transactions.

Expenses of the Reorganization

        BlackRock, MLIM or their affiliates will pay the expenses incurred in connection with the Reorganization, including all direct and indirect expenses and out-of-pocket costs. Neither the Funds nor their shareholders will bear any of the expenses incurred in connection with the Reorganization. Any brokerage or other trading costs incurred by a Fund in connection with buying or selling portfolio securities prior to the Reorganization will be borne by that Fund.

        Expenses incurred in connection with the Reorganization include, but are not limited to: all costs related to the preparation and distribution of materials distributed to each Fund’s Board including legal and accounting costs; all expenses incurred in connection with the preparation of the Reorganization Agreement and a registration statement on Form N-14; SEC and state securities commission filing fees and legal and audit fees in connection with the Reorganization; the costs of printing and distributing this Combined Prospectus/Proxy Statement; auditing fees associated with inclusion of each Fund’s financial statements in the Form N-14; portfolio transfer taxes (if any); and any similar expenses incurred in connection with the Reorganization. Neither of the Funds will pay any expenses of shareholders arising out of or in connection with the Reorganization.

        All other expenses of each of the parties shall be paid by the applicable party.

Continuation of Shareholder Accounts and Plans; Share Certificates

        If the Reorganization is approved, the ML Fund will establish an account for each BlackRock Fund shareholder containing the appropriate number of shares of the ML Fund. Shareholders of the BlackRock Fund who are accumulating BlackRock Fund shares under the dividend reinvestment plan who are receiving payment under the systematic withdrawal plan, or who benefit from special sales programs with respect to BlackRock Fund shares will retain the same rights and privileges after the Reorganization in connection with the shares of the ML Fund received in the Reorganization through similar plans maintained by the ML Fund. Shareholders of the combined fund who are enrolled in the automatic investment plan may be asked to terminate such plan and enroll in a new automatic investment plan for a different class of shares in the ML Fund. Such shareholders should note that such other classes of shares are subject to different fees and expenses than their original shares and should read the ML Fund Prospectus for additional information.

        It will not be necessary for shareholders of the BlackRock Fund to whom certificates have been issued to surrender their certificates. Upon termination of the BlackRock Fund, such certificates will become null and void. No certificates for the ML Fund will be issued.

Legal Matters

        Certain legal matters concerning the federal income tax consequences of the Reorganization and issuance of shares of the ML Fund will be passed on by Sidley Austin LLP , which serves as counsel to the ML Fund.

OTHER INFORMATION

Capitalization

        The BlackRock Fund currently offers five classes of shares (Investor A, B and C Shares, Institutional Shares and Service Shares). The ML Fund offers five classes of shares (Class A, B, C, I and R Shares, which will be renamed Investor A, Investor B, Investor C, Institutional and R Shares, respectively), and, in connection with the Reorganization, will issue an additional new class of Service Shares.

        The following table sets forth as of October 31, 2005: (i) the unaudited capitalization of the BlackRock Fund; (ii) the unaudited capitalization of the ML Fund; and (iii) the unaudited pro forma combined capitalization of the ML Fund assuming the Reorganization has been approved. The capitalizations are likely to be different when the Reorganization is scheduled to be completed as a result of daily share purchase and redemption activity.

Shareholder Rights and Obligations

        While the BlackRock Fund and the ML Fund are different entities and, thus, governed by different organizational documents, the Reorganization will not result in material differences in shareholder rights. The shares of the ML Fund to be distributed to shareholders of the BlackRock Fund will generally have the same legal characteristics as the shares of the BlackRock Fund with respect to such matters as voting rights, accessibility, and transferability.

        Under their respective organizational documents, the BlackRock Fund is authorized to issue an unlimited number of shares of beneficial interest with a par value of $0.001 per share, and the ML Fund is authorized to issue 700,000,000 shares divided into five classes, Class A, Class B, Class C, Class I and Class R. Class A, Class C and Class I common stock each consists of 100,000,000 authorized shares, and Class B and Class R each consists of 200,000,000 authorized shares, in each case with a par value of $0.10 per share. In connection with the Reorganization, the ML Fund has authorized the issuance of newly created Service Shares. The BlackRock Fund Board and the ML Fund Board may, without limitation, classify or reclassify any unissued shares of the BlackRock Fund or the ML Fund into any number of additional classes of shares. The BlackRock Fund Board and the ML Fund Board may also, without limitation, classify or reclassify any unissued shares into one or more additional series, each with its own assets and liabilities.

        Each of the BlackRock Fund and the ML Fund will continue indefinitely until terminated.

        With respect to each Fund, shares of the same class within such Fund have equal dividend, distribution, liquidation, and voting rights, and fractional shares have those rights proportionately. Each Fund and class of shares within such Fund bears its own expenses related to its distribution of shares (and other expenses such as shareholder or administrative services).

        Unless (i) the ML Fund Board has determined that a matter only affects the interests of one or more class or classes (in which case only shareholders of the affected class or classes are entitled to vote) or (ii) otherwise required by applicable law, on any matter submitted to a vote of shareholders of the ML Fund, all shares entitled to vote are voted in the aggregate and not by class. The shares of the BlackRock Fund have substantially similar voting rights.

        There are no preemptive rights in connection with shares of either Fund. When issued in accordance with the provisions of their respective prospectuses, all shares are fully paid and non-assessable.

        The ML Fund is a series of ML Series and the BlackRock Fund is a series of BlackRock Funds. ML Series is a corporation organized under the laws of the State of Maryland and BlackRock Funds is a business trust organized under the laws of the Commonwealth of Massachusetts. Under Massachusetts law, shareholders of a business trust may, under certain circumstances, be held personally liable as partners for the obligations of the trust. However, the Declaration of Trust of BlackRock Funds provides that shareholders shall not be subject to any personal liability in connection with the assets of the BlackRock Fund for the acts or obligations of the BlackRock Fund, and that every note, bond, contract, order or other undertaking made by the BlackRock Fund shall contain a provision to the effect that the shareholders are not personally liable thereunder. The Declaration of Trust of BlackRock Funds provides for indemnification out of the trust property of any shareholder held personally liable solely by reason of his being or having been a shareholder and not because of his acts or omissions or some other reason. The Declaration of Trust of BlackRock Funds also provides that the BlackRock Fund shall, upon request, assume the defense of any claim made against any shareholder for any act or obligation of the BlackRock Fund, and shall satisfy any judgment thereon.

         The foregoing is only a summary of certain rights of shareholders under the charter documents governing the BlackRock Fund and the ML Fund and applicable state law, and is not a complete description of provisions contained in those sources. Shareholders should refer to the provisions of those documents and state law directly for a more thorough description.

Shareholder Proposals

        The Funds do not hold regular annual meetings of shareholders. As a general matter, the ML Fund does not intend to hold future regular annual or special meetings of its shareholders unless required by the 1940 Act. In the event the Reorganization is not completed, the BlackRock Fund does not intend to hold future regular annual or special meetings of its shareholders unless required by the 1940 Act. Any shareholder who wishes to submit proposals for consideration at a meeting of shareholders of the BlackRock Fund should send such proposal to BlackRock, Inc., Attn: Robert Connolly, 40 East 52nd St., New York, New York 10022. Any shareholder who wishes to submit proposals for consideration at a meeting of shareholders of the ML Fund should send such proposal to the Secretary of the ML Fund, 800 Scudders Mill Road, Plainsboro, New Jersey 08536. To be considered for presentation at a shareholders’ meeting, rules promulgated by the SEC require that, among other things, a shareholder’s proposal must be received at the offices of the Fund a reasonable time before a solicitation is made. Timely submission of a proposal does not necessarily mean that such proposal will be included.

Solicitation of Proxies

        Solicitation of proxies is being made on behalf of the BlackRock Fund and the BlackRock Fund Board primarily by the mailing of this Notice and Combined Prospectus/Proxy Statement with its enclosures on or about June 23, 2006. BlackRock Fund shareholders whose shares are held by nominees such as brokers can vote their proxies by contacting their respective nominee. In addition to the solicitation of proxies by mail, employees of the BlackRock Fund and its affiliates as well as dealers or their representatives may, without additional compensation, solicit proxies in person or by mail, telephone, facsimile or oral communication. The BlackRock Fund has retained Computershare Fund Services (“Computershare”), a professional proxy solicitation firm, to assist with any necessary solicitation of proxies. BlackRock Fund shareholders may receive a telephone call from Computershare asking them to vote. Computershare and its agents will assist with the mailing and tabulation effort and may also solicit Proxies by contacting shareholders by telephone. The costs of solicitation will be borne by MLIM, BlackRock or their affiliates. The cost for the services of Computershare in connection with the proposed Reorganization is not expected to exceed $25,000.

        Brokerage firms and others will be reimbursed for their expenses in forwarding solicitation material to the beneficial owners of shares of the BlackRock Fund. Representatives of BlackRock Advisors and its affiliates and other representatives of the BlackRock Fund may also solicit proxies. Questions about the proposal should be directed to Computershare at 1-866-390-5114.

VOTING INFORMATION AND REQUIREMENTS

General

        This Combined Prospectus/Proxy Statement is furnished in connection with the proposed Reorganization of the BlackRock Fund into the ML Fund and the solicitation of proxies by and on behalf of the BlackRock Fund Board for use at the Special Meeting of shareholders of the BlackRock Fund. The Special Meeting will be held on Tuesday August 22, 2006 at 11:00 a.m., Eastern time, at the Omni Berkshire Place, 21 East 52nd Street, New York, New York 10022, or at such later time as is made necessary by adjournment or postponement.

        As of May 25, 2006, the BlackRock Fund had the following number of shares outstanding:

        Only shareholders of record on May 25, 2006 will be entitled to notice of and to vote at the Special Meeting. Each share is entitled to one vote, with fractional shares voting proportionally.

Shareholder Approval

        Approval by the BlackRock Fund of the proposed Reorganization will require the affirmative vote of the holders of a majority of the outstanding shares entitled to vote, as defined under the 1940 Act. The 1940 Act defines such vote as the lesser of (i) 67% or more of the total number of shares of all classes of a fund present or represented by proxy at the Special Meeting, voting together as a single class, if holders of more than 50% of the outstanding shares of all classes, taken as a single class, are present or represented by proxy at the Special Meeting; or (ii) more than 50% of the total number of outstanding shares of all classes of such fund, voting together as a single class. If the shareholders fail to approve the proposed Reorganization, the Reorganization will not occur. The BlackRock Fund Board has fixed the close of business on May 25, 2006 as the Record Date for the determination of shareholders entitled to notice of, and to vote at, the Special Meeting. BlackRock Fund shareholders on the Record Date are entitled to one vote for each share held, with no shares having cumulative voting rights.

        If a proxy authorization (“Proxy”) is properly given in time for a vote at the Special Meeting (either by returning the paper Proxy form or by submitting a Proxy by telephone or over the internet), the shares of the BlackRock Fund represented thereby will be voted at the Special Meeting in accordance with the shareholder’s instructions. The Proxy grants discretion to the persons named therein, as proxies, to take such further action as

they may determine appropriate in connection with any other matter which may properly come before the Special Meeting or any adjournments thereof. The BlackRock Fund Board does not currently know of any matter to be considered at the Special Meeting other than the matters set forth in the Notice of Special Meeting of Shareholders.

        A majority of the outstanding shares entitled to vote on a proposal must be present in person or by proxy to have a quorum to conduct business at the Special Meeting.

        The persons named as proxies may, whether or not a quorum is present, propose one or more adjournments of the Special Meeting on behalf of the BlackRock Fund without further notice to permit further solicitation of Proxies, provided such persons determine that an adjournment and additional solicitation are reasonable and in the interest of the shareholders of the BlackRock Fund, after consideration of all relevant factors, including the nature of the relevant proposal, the percentage of votes then cast, the percentage of negative votes then cast, the nature of the proposed solicitation activities and the nature of the reasons for such solicitation. Any such adjournment will require the affirmative vote of the holders of a majority of the shares of the BlackRock Fund present in person or by proxy and entitled to vote at the session of the Special Meeting to be adjourned. Those proxies which are instructed to vote in favor of the Reorganization will vote in favor of any such adjournment, and those proxies which are instructed to vote against the Reorganization will vote against any such adjournment, as applicable.

        All properly executed Proxies received prior to the Special Meeting will be voted in accordance with the instructions marked thereon or otherwise as provided therein. For purposes of determining the presence of a quorum for transacting business at the Special Meeting and determining whether sufficient votes have been received for approval of any proposal to be acted upon at the Special Meeting, abstentions may, in the discretion of the BlackRock Fund, be treated as shares that are present at the Special Meeting and entitled to vote on the matter, but that have not been voted. Unless instructions to the contrary are marked, properly executed Proxies will be voted “For” the approval of the proposed Reorganization. Abstentions and broker non-votes ( i.e. , where a nominee such as a broker holding shares for beneficial owners votes on certain matters pursuant to discretionary authority or instructions from beneficial owners, but with respect to one or more proposals does not receive instructions from beneficial owners or does not exercise discretionary authority) will be counted as present for purposes of a quorum but would have the same effect as votes “Against” the Reorganization.

        Broker-dealer firms holding shares in “street name” for the benefit of their customers and clients will request the instructions of such customers and clients on how to vote their shares on each proposal before the Special Meeting. The New York Stock Exchange (the “NYSE”) has taken the position that broker-dealers that are members of the NYSE and that have not received instructions from a customer prior to the date specified in the broker-dealer firms’ request for voting instructions may not vote such customer’s shares on the Reorganization proposal. A signed proxy card or other authorization by a beneficial owner of shares that does not specify how the beneficial owner’s shares are to be voted on a proposal may be deemed to be an instruction to vote such shares in favor of the applicable proposal.

Manner of Voting

        BlackRock Fund shareholders may vote by appearing in person at the Special Meeting, by returning the enclosed Proxy form or by casting their vote via telephone or the internet using the instructions provided on the enclosed Proxy form. Any shareholder who has given a Proxy, whether in written form, by telephone or over the internet, may revoke it at any time prior to its exercise by submitting a subsequent written, telephonic or electronic vote, by giving written notice of revocation to the Secretary of the BlackRock Fund, or by voting in person at the Special Meeting.

         Voting by Mail. To vote by mail, you should date and sign the Proxy card included with this Combined Prospectus/Proxy Statement, indicate your vote on the proposal, and return the card in the envelope provided.

         Voting by Telephone. There are two convenient methods to vote by telephone. If telephone voting is available for your account, a toll-free telephone number will be printed on your Proxy card. Prior to calling, you should read the Combined Prospectus/Proxy Statement and have your Proxy card at hand. (Please note, however, that telephone voting may not be available to shareholders whose shares are held by a broker or other intermediary on the shareholder’s behalf.)

        First, you may use the automated touch-tone voting method by calling the toll-free number provided on the Proxy card. At the prompt, follow the menu.

        Second, a separate toll-free number is provided on the Proxy card for registered shareholders who wish to speak to a telephone representative directly and give verbal instructions. The telephone representative will assist the shareholder with the voting process. The representative will not be able to assist a shareholder with information that is not contained in the Combined Prospectus/Proxy Statement, and the representative will not make recommendations on how to vote on the proposal.

         Internet Voting. To vote over the internet, please log on to the website printed on your proxy card. Prior to logging on, you should read the Combined Prospectus/Proxy Statement and have your Proxy card at hand. After logging on, follow the instructions on the screen. If you receive more than one Proxy card, you may vote them during the same session. (Please note, however, that internet voting may not be available to shareholders whose shares are held by a broker or other intermediary on the shareholder’s behalf.)

         Additional Information. Shareholders voting their Proxies by telephone or over the internet need not return their Proxy cards by mail.

        A person submitting votes by telephone or over the internet is deemed to represent that he or she is authorized to vote on behalf of all owners of the account, including spouses or other joint owners. By using the telephone or the internet to submit voting instructions, the shareholder is authorizing Computershare, a proxy solicitation firm, and its agents, to execute a Proxy to vote the shareholder’s shares at the Special Meeting as the shareholder has indicated.

        The BlackRock Fund believes that the procedures for authorizing the execution of a Proxy by telephone or over the internet set forth above are reasonably designed to ensure that the identity of the shareholder casting the vote is accurately determined and that the voting instructions of the shareholder are accurately recorded.

        You are requested to fill in, sign and return the enclosed Proxy card promptly even if you expect to be present in person at the Special Meeting since you can always reverse your vote at the Special Meeting and unexpected circumstances might prevent you from attending. No postage is necessary if mailed in the United States.

        WHEREAS, the Board of Trustees of BlackRock Funds on behalf of BR Large Cap Value has determined that the Reorganization is in the best interests of BR Large Cap Value and that the interests of the existing shareholders of BR Large Cap Value will not be diluted as a result of the Reorganization;

ARTICLE I

TRANSFER OF SUBSTANTIALLY ALL OF THE ASSETS OF BR LARGE CAP VALUE IN EXCHANGE FOR
ML LARGE CAP VALUE SHARES AND THE ASSUMPTION OF THE STATED
LIABILITIES OF BR LARGE CAP VALUE AND THE LIQUIDATION OF BR LARGE CAP VALUE

       1.1 THE EXCHANGE. Subject to the terms and conditions contained herein and on the basis of the representations and warranties contained herein, BR Large Cap Value agrees to convey, transfer and deliver substantially all the assets of BR Large Cap Value described in paragraph 1.2 to ML Large Cap Value free and clear of all liens, encumbrances and claims whatsoever. In exchange, ML Large Cap Value agrees: (a) to deliver to BR Large Cap Value the number of full and fractional shares of each corresponding class of ML Large Cap
 

Value, determined by dividing: (i) the aggregate value of BR Large Cap Value’s assets, net of the liabilities of BR Large Cap Value, attributable to each share class of BR Large Cap Value (as set forth below), computed in the manner and as of the time and date set forth in paragraph 2.1, by (ii) the net asset value of one ML Large Cap Value Share of the corresponding class (as set forth below) computed in the manner and as of the time and date set forth in paragraph 2.2; and (b) to assume the Stated Liabilities of BR Large Cap Value described in paragraph 1.3. Such transactions shall take place at the closing (the “Closing”) provided for in paragraph 3.1.

        The classes of shares of ML Large Cap Value correspond to the classes of shares of BR Large Cap Value as follows: Class A shares of ML Large Cap Value correspond to Investor A shares of BR Large Cap Value, Class B shares of ML Large Cap Value correspond to Investor B shares of BR Large Cap Value, Class C shares of ML Large Cap Value correspond to Investor C shares of BR Large Cap Value, Class I shares of ML Large Cap Value correspond to Institutional Shares of BR Large Cap Value and newly-created Service Shares of ML Large Cap Value correspond to Service Shares of BR Large Cap Value. The Class A, Class B, Class C and Class I shares of ML Large Cap Value will be redesignated Investor A, Investor B, Investor C and Institutional Shares in connection with the Reorganization.

        1.2 ASSETS TO BE ACQUIRED. The assets of BR Large Cap Value to be acquired by ML Large Cap Value shall consist of all property owned by BR Large Cap Value, including, without limitation, all cash, securities, commodities, interests in futures and other financial instruments, claims (whether absolute or contingent, known or unknown), receivables (including dividends, interest, principal, subscriptions and other receivables), goodwill and other intangible property, all books and records belonging to BR Large Cap Value, any deferred or prepaid expenses shown as an asset on the books of BR Large Cap Value on the Closing Date, and all interests, rights, privileges and powers, other than cash in an amount necessary to pay dividends and distributions as provided in paragraph 7.3 and other than BR Large Cap Value’s rights under this Agreement (the “Assets”).

        BR Large Cap Value will, within 7 days prior to the Closing Date, furnish ML Large Cap Value with (a) a list of BR Large Cap Value’s portfolio securities and other investments and (b) a list of BR Large Cap Value’s “historic business assets,” which are defined for this purpose as (i) those assets that were acquired by BR Large Cap Value prior to the date of the approval of the Reorganization by the Board of Trustees of BlackRock Funds on behalf of BR Large Cap Value, and (ii) those assets that were acquired subsequent to such board approval but in accordance with BR Large Cap Value’s investment objectives and not with a view to, or in anticipation or as part of, the Reorganization. ML Large Cap Value will, within 3 days prior to the Closing Date, furnish BR Large Cap Value with a list of the securities and other instruments, if any, on BR Large Cap Value’s list referred to above that do not conform to ML Large Cap Value’s investment objectives, policies and restrictions. If requested by ML Large Cap Value, BR Large Cap Value will dispose of securities and other instruments on ML Large Cap Value’s list before the Closing Date. In addition, if it is determined that the portfolios of BR Large Cap Value and ML Large Cap Value, when aggregated, would contain investments exceeding certain percentage limitations imposed upon ML Large Cap Value with respect to such investments, BR Large Cap Value, if requested by ML Large Cap Value, will dispose of a sufficient amount of such investments as may be necessary to avoid violating such limitations as of the Closing Date. After BR Large Cap Value furnishes ML Large Cap Value with the list described above, BR Large Cap Value will not, without the prior approval of ML Large Cap Value, acquire any additional securities other than securities which ML Large Cap Value is permitted to purchase pursuant to its investment objective and policies or otherwise (taking into consideration its own portfolio composition as of such date). Notwithstanding the foregoing, (a) nothing herein will require BR Large Cap Value to dispose of any portfolio securities or other investments, if, in the reasonable judgment of BlackRock Funds’ Board of Trustees on behalf of BR Large Cap Value or investment adviser, such disposition would adversely affect the tax-free nature of the Reorganization for federal income tax purposes or would otherwise not be in the best interests of BR Large Cap Value and (b) nothing will permit BR Large Cap Value to dispose of any portfolio securities or other investments if, in the reasonable judgment of ML Large Cap Value’s Board of Directors or investment adviser, such disposition would adversely affect the tax-free nature of the Reorganization for federal income tax purposes or would otherwise not be in the best interests of ML Large Cap Value.

        1.3 LIABILITIES TO BE ASSUMED. BR Large Cap Value will endeavor to identify and discharge, to the extent practicable, all of its liabilities and obligations, including all liabilities relating to operations, before the Closing Date.

Upon completion of the distribution of all of the ML Large Cap Value Shares in accordance with the prior sentence, BR Large Cap Value will thereupon proceed to dissolve and terminate as set forth in paragraph 1.9 below. Such distribution will be accomplished by the transfer on the books of ML Large Cap Value of ML Large Cap Value Shares credited to the account of BR Large Cap Value to open accounts on the share records of ML Large Cap Value in the name of BR Large Cap Value Shareholders, and representing the respective pro rata number of each class of ML Large Cap Value Shares due BR Large Cap Value Shareholders holding the corresponding class of BR Large Cap Value shares.

        1.8 REPORTING RESPONSIBILITY. Any reporting responsibility of BR Large Cap Value, including, without limitation, the responsibility for filing of regulatory reports, tax returns or other documents with the Securities and Exchange Commission (the “Commission”), any state securities commission, and any federal, state or local tax authorities or any other relevant regulatory authority, is and shall remain the responsibility of BR Large Cap Value or of BlackRock Funds, on behalf of BR Large Cap Value.

        (a) the transfer of all of the Assets solely in exchange for ML Large Cap Value Shares and the assumption by ML Large Cap Value of the Stated Liabilities of BR Large Cap Value followed by the distribution of ML Large Cap Value Shares to BR Large Cap Value Shareholders in complete dissolution and liquidation of BR Large Cap Value will constitute a “reorganization” within the meaning of Section 368(a) of the Code and ML Large Cap Value and BR Large Cap Value will each be a “party to a reorganization” within the meaning of Section 368(b) of the Code;

        (b) no gain or loss will be recognized by ML Large Cap Value upon the receipt of all of the Assets solely in exchange for ML Large Cap Value Shares and the assumption by ML Large Cap Value of the Stated Liabilities of BR Large Cap Value;

        (c) no gain or loss will be recognized by BR Large Cap Value upon the transfer of the Assets to ML Large Cap Value solely in exchange for ML Large Cap Value Shares and the assumption by ML Large Cap Value of the Stated Liabilities of BR Large Cap Value or upon the distribution (whether actual or constructive) of ML Large Cap Value Shares to BR Large Cap Value Shareholders in exchange for such shareholders’ shares of BR Large Cap Value in liquidation of BR Large Cap Value;

        (d) no gain or loss will be recognized by BR Large Cap Value Shareholders upon the exchange of their BR Large Cap Value shares solely for ML Large Cap Value Shares in the Reorganization;

        (e) the aggregate tax basis of ML Large Cap Value Shares received by each BR Large Cap Value Shareholder pursuant to the Reorganization will be the same as the aggregate tax basis of BR Large Cap Value shares exchanged therefor by such shareholder;

        (f) the holding period of ML Large Cap Value Shares to be received by each BR Large Cap Value Shareholder pursuant to the Reorganization, including fractional shares to which he, she or it may be entitled, will include the period during which BR Large Cap Value shares exchanged therefor were held by such shareholder, provided such BR Large Cap Value shares are held as capital assets at the time of the Reorganization;

        (g) the tax basis of the Assets acquired by ML Large Cap Value will be the same as the tax basis of such Assets to BR Large Cap Value immediately before the Reorganization;

        (h) the holding period of the Assets in the hands of ML Large Cap Value will include the period during which those assets were held by BR Large Cap Value;

        (i) neither ML Large Cap Value nor the Master Portfolio will recognize gain or loss on the transfer by ML Large Cap Value to the Master Large Cap Value Portfolio of the Assets received in exchange for beneficial interests in the Master Large Cap Value Portfolio;

        (j) ML Large Cap Value’s tax basis in the Master Large Cap Value Portfolio beneficial interests received in exchange for the Assets transferred by ML Large Cap Value will equal its basis in the Assets transferred;

        (k) the tax basis of the Assets in the hands of the Master Large Cap Value Portfolio will be the same as their tax basis in the hands of ML Large Cap Value;

        (l) ML Large Cap Value’s holding period in the Master Large Cap Value Portfolio beneficial interests received in exchange for the transferred Assets will include its holding period for the Assets transferred; and

        (m) the Master Large Cap Value Portfolio’s holding period for the Assets received from ML Large Cap Value will include ML Large Cap Value’s holding period for such Assets.

        Such opinion shall be based on customary assumptions and such representations as Sidley Austin LLP may reasonably request, and each of Master Large Cap Trust, ML Large Cap Series, ML Large Cap Value and BlackRock Funds and BR Large Cap Value will cooperate to make and certify the accuracy of such

representations. Notwithstanding anything herein to the contrary, neither Master Large Cap Trust, ML Large Cap Series, ML Large Cap Value, BlackRock Funds nor BR Large Cap Value may waive the condition set forth in this paragraph 8.6.
