BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 A Letter to Shareholders Dear Shareholder The new year began on a positive note for most financial markets, continuing the momentum from the fourth quarter of 2006. At the end of February, however, global equity markets registered their first significant decline since last summer. The market jitters were triggered by a significant setback in the Chinese market and were exacerbated by several concerns, notably a weakening economy, some disappointing corporate earnings announcements, geopolitical concerns related to Iran's nuclear program and increasing delinquencies in the subprime mortgage market. Despite the recent spate of volatility, underlying stock market fundamentals appear quite sound, supported by a generally good global economic backdrop, tame inflation, relatively low interest rates and attractive valuations. Not unlike the equity market, the bond market also has seen volatility recently as observers have attempted to interpret mixed economic signals. A bond market rally late last year reversed early in 2007 as the economic data strengthened. Prices improved (and yields fell) again in February as equities struggled. Notably, the Treasury curve remained inverted for much of 2006 and into 2007. The 30-year Treasury yield stood at 4.68% on February 28, 2007, while the one-month Treasury offered the highest yield on the curve at 5.24%. For its part, the Federal Reserve Board (the Fed) has left the target short- term interest rate on hold at 5.25% since first pausing on August 8, 2006. Although the central bankers continue to express concern about potential inflationary pressures, they also have made reference to signs of economic weakness in their public statements. Most observers expect the Fed to keep interest rates on hold for now, but acknowledge that the combination of a mild economic slowdown and moderating inflation could prompt an interest rate cut later in 2007. Notwithstanding the volatility along the way, most major market indexes managed to post positive returns for the annual and semi-annual reporting periods ended February 28, 2007: Total Returns as of February 28, 2007 6-month 12-month U.S. equities (Standard & Poor's 500 Index) + 8.93% +11.97% Small cap U.S. equities (Russell 2000 Index) +10.76 + 9.87 International equities (MSCI Europe, Australasia, Far East Index) +12.17 +21.07 Fixed income (Lehman Brothers Aggregate Bond Index) + 3.66 + 5.54 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 2.89 + 4.96 High yield bonds (Credit Suisse High Yield Index) + 8.62 +12.36 If the recent market movements are any guide, 2007 could be a year of enhanced market volatility. As you navigate the uncertainties of the financial markets, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed. We thank you for trusting BlackRock with your investment assets, and we look forward to continuing to serve you in the months and years ahead. Sincerely, (Robert C. Doll, Jr.) Robert C. Doll, Jr. Fund President and Trustee BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 A Discussion With Your Fund's Portfolio Manager The Fund continued to meet its primary objective of preserving investor principal during the semi-annual reporting period. How did the Fund perform during the period in light of the existing market conditions? For the six-month period ended February 28, 2007, BlackRock Fundamental Growth Principal Protected Fund's Institutional, Investor A, Investor B and Investor C Shares had total returns of +1.58%, +1.58%, +1.20% and +1.09%, respectively. For the same period, the Fund's all-equity benchmark, the S&P 500 Citigroup Growth Index, returned +7.18%, while the broader U.S. equity market, as measured by the S&P 500 Index, gained 8.93%. (Fund results shown do not reflect sales charges and would be lower if sales charges were included. Complete performance information can be found on pages 6 and 7 of this report to shareholders.) The Lipper category of Mixed-Asset Target Allocation Growth Funds posted an average return of +7.56% for the six-month period. (By portfolio practice, funds in this Lipper category maintain a mix of 60% - 80% equity securities, with the remainder invested in bonds, cash and cash equivalents.) The Fund incorporates a fixed income component and, therefore, its returns will necessarily differ from those of the equity markets alone. The fixed income market, as measured by the Lehman Brothers Aggregate Bond Index, returned +3.66% for the six-month period. Given the comparatively strong performance of the equity markets, the fixed income component hindered the Fund's results. Likewise, the positioning of the equity portfolio detracted from performance in what was a challenging period for the large cap growth style of investing. During the six-month reporting period, small- and mid-sized companies led the market out of the bottom that had been reached in mid-July 2006. In addition, a general bias toward value investing continued to dominate throughout the period. Concerns about the direction and magnitude of growth in the U.S. economy also significantly influenced market leadership, as a clear defensive tone emerged with renewed investor interest in "mega caps" (that is, the largest companies as measured by market cap) evident across most sectors. This tended to favor market-capitalization-weighted indexes over individual growth stock selection. Furthermore, investor perceptions and definitions of growth and value became increasingly ambiguous against this backdrop. The new year opened with equity markets performing strongly until the end of February, when investor concerns over global risk premiums once again sent global equity markets into a corrective phase. The performance of the Fund's equity portfolio was negatively influenced by our conviction that growth stocks were attractive investments, while the market, in general, had become more defensive. Consequently, the Fund's underperformance versus the largely market-weighted benchmark resulted from an underrepresentation in "mega cap" stocks, in addition to adverse security selection. In particular, we saw poor performance among portfolio holdings in the consumer discretionary, health care and information technology sectors. Conversely, stock selection in the materials and financials sectors was modestly favorable, as were the Fund's underweight positions in consumer staples and health care. The Fund's relative performance improved measurably by the end of the period (specifically, year-to-date through February), as our positioning gained investor acceptance. Individual Fund holdings that detracted from performance during the six-month period included Medco Health Solutions, Inc., CVS Corp., WellPoint, Inc., Motorola, Inc. and Corning, Inc. At the same time, several names were notably additive to performance, including Cognizant Technology Solutions Corp., Infosys Technologies Ltd., Nike, Inc., Pall Corp. and Nalco Holding Co. Avoidance of Pfizer, Inc. and Johnson & Johnson aided relative performance, while lack of exposure to Microsoft Corp. detracted. What changes were made to the portfolio during the period? A mathematical formula is used to determine the allocation between the Fund's equity and fixed income components. During the six-month period, the Fund's equity component ranged from a high of 68.1% of net assets to a low of 55.6%, while the fixed income allocation ranged from as much as 44.4% of net assets to 31.9%. The Fund's fixed income component was invested in U.S. Treasury zero- coupon bonds set to mature close to the expiration of the Fund, which is seven years from its commencement of operations (November 13, 2009). BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 We made strides in repositioning the equity portfolio after the mid-2006 market correction to adjust to a more moderate rate of economic growth in the United States and shifts in sector leadership. To that end, we reduced our overweight position in energy to a slight underweight, while increasing our position in information technology from an underweight to a modest overweight. We also trimmed the portfolio's overweighting in industrials and exited the managed-care industry, thereby reducing overall exposure to the health care sector. Finally, we increased the portfolio's positions in the consumer discretionary and financials sectors, particularly in retail and capital markets-related companies, respectively. In terms of individual stocks, significant additions included Coach Inc., Thermo Fisher Scientific, Inc., Target Corp., EMC Corp., The Goldman Sachs Group, Inc., American International Group, Inc., Oracle Corp. and Comcast Corp. Significant sales or reductions included WellPoint, Inc., Altria Group, Inc., Exxon Mobil Corp. (which we sold and repurchased within the period), Bank of America Corp., Medco Health Solutions, Inc., CVS Corp., The Procter & Gamble Co., Valero Energy Corp., Alcon, Inc., GlaxoSmithKline Plc and Amgen, Inc. How would you characterize the Fund's position at the close of the period? In seeking to meet its objective of principal protection and potential for capital growth, the allocation between the Fund's fixed income and equity components will continue to vary as market conditions change. As of February 28, 2007, the Fund was invested 57.8% in equities and 42.2% in fixed income securities. This compared to 58.8% equities and 41.2% fixed income at August 31, 2006. U.S. economic growth (that is, gross domestic product growth) has slowed to a slightly below-trend rate of expansion (in the area of 2% - 3%). We view this as a typical mid-cycle slowdown and do not expect a recession to unfold. In fact, we suspect there is upside risk to accelerating economic growth in the United States by year-end 2007. At this time, it appears as if inflation expectations have been well-contained via adequate Federal Reserve Board policy initiatives. While most other global economies, particularly those in Europe and Asia, continue to experience strong rates of growth, we are reviewing portfolio positioning in light of apparent changes recently (late February) in market risk parameters. Although this mid-cycle slowdown may challenge broader market (S&P 500 Index) earnings growth over the near term, we believe it should provide an attractive investment environment for select growth stocks going forward. At the end of the period, the Fund's equity portfolio was overweight relative to its benchmark in the consumer discretionary, information technology and materials sectors, and had significant underweights in consumer staples and health care.

BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Performance Data About Fund Performance Effective October 2, 2006, the Fund's Class A, Class B, Class C and Class I Shares were redesignated Investor A, Investor B, Investor C and Institutional Shares, respectively. As previously communicated to shareholders, new sales charge schedules came into effect at the same time for certain of these classes. The Fund has multiple classes of shares: * Institutional Shares are not subject to any front-end sales charge. Institutional Shares bear no ongoing distribution or service fees and are available only to eligible investors. * Investor A Shares incur a maximum initial sales charge (front-end load) of 5.25% and a service fee of 0.25% per year (but no distribution fee). * Investor B Shares are subject to a maximum contingent deferred sales charge of 4.50% declining to 0% after six years. In addition, Investor B Shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. These shares automatically convert to Investor A Shares after approximately eight years. (There is no initial sales charge for automatic share conversions.) All returns for periods greater than eight years reflect this conversion. * Investor C Shares are subject to a distribution fee of 0.75% per year and a service fee of 0.25% per year. In addition, Investor C Shares are subject to a 1% contingent deferred sales charge if redeemed within one year of purchase. Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com to obtain performance data current to the most recent month-end. Performance results do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Figures shown in each of the following tables assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the ex-dividend date. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. Dividends paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Disclosure of Expenses Shareholders of this Fund may incur the following charges: (a) expenses related to transactions, including sales charges, redemption fees and exchange fees; and (b) operating expenses including advisory fees, distribution fees including 12b-1 fees, and other Fund expenses. The following example (which is based on a hypothetical investment of $1,000 invested on September 1, 2006 and held through February 28, 2007) is intended to assist shareholders both in calculating expenses based on an investment in the Fund and in comparing these expenses with similar costs of investing in other mutual funds. The first table below provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number in the first line under the heading entitled "Expenses Paid During the Period." The second table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses. In order to assist shareholders in comparing the ongoing expenses of investing in this Fund and other funds, compare the 5% hypothetical example with the 5% hypothetical examples that appear in other funds' shareholder reports. The expenses shown in the table are intended to highlight shareholders' ongoing costs only and do not reflect any transactional expenses, such as sales charges, redemption fees or exchange fees. Therefore, the second table is useful in comparing ongoing expenses only, and will not help shareholders determine the relative total expenses of owning different funds. If these transactional expenses were included, shareholder expenses would have been higher. Expenses Paid Beginning Ending During the Period* Account Value Account Value September 1, 2006 September 1, February 28, to February 28, 2006 2007 2007 Actual Institutional $1,000 $1,015.80 $ 9.10 Investor A $1,000 $1,015.80 $10.35 Investor B $1,000 $1,012.00 $14.12 Investor C $1,000 $1,010.90 $14.11 Hypothetical (5% annual return before expenses)** Institutional $1,000 $1,015.77 $ 9.10 Investor A $1,000 $1,014.54 $10.34 Investor B $1,000 $1,010.77 $14.11 Investor C $1,000 $1,010.77 $14.11 * For each class of the Fund, expenses are equal to the annualized expense ratio for the class (1.82% for Institutional, 2.07% for Investor A, 2.83% for Investor B and 2.83% for Investor C), multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period shown). ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year divided by 365.

See Notes to Financial Statements. BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Notes to Financial Statements (Unaudited) 1. Significant Accounting Policies: BlackRock Fundamental Growth Principal Protected Fund (the "Fund") is part of BlackRock Principal Protected Trust (the "Trust"). The Fund is a separate diversified series of the Trust, which is registered as an open-end management investment company under the Investment Company Act of 1940, as amended. The Fund's financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. These unaudited financial statements reflect all adjustments, which are, in the opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Fund offers multiple classes of shares. Shares of the Fund were offered during the initial offering period but will not be offered during the Guarantee Period from November 13, 2002 through November 13, 2009 (the "Guarantee Maturity Date"), except in connection with reinvestment of dividends and distributions. The Fund will be offered on a continuous basis after the Guarantee Maturity Date without the principal protection feature. Effective October 2, 2006, Class I, Class A, Class B and Class C Shares were redesignated Institutional, Investor A, Investor B and Investor C Shares, respectively. Institutional Shares are sold only to certain eligible investors. Investor A Shares are sold with a front-end sales charge. Shares of Investor B and Investor C may be subject to a contingent deferred sales charge. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Investor A, Investor B and Investor C Shares bear certain expenses related to the shareholder servicing of such shares, and Investor B and Investor C Shares also bear certain expenses related to the distribution of such shares. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B shareholders may vote on certain changes to the Investor A distribution plan). Income, expenses (other than expenses attributable to a specific class) and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Equity securities held by the Fund that are traded on stock exchanges or the NASDAQ Global Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Fund. Long positions traded in the over-the-counter ("OTC") market, NASDAQ Capital Market or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Fund. Short positions traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., believes that this method no longer produces fair valuations. Valuation of other short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Repurchase agreements are valued at cost plus accrued interest. The Fund employs pricing services to provide certain securities prices for the Fund. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Fund, including valuations furnished by the pricing services retained by the Fund, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Fund's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Fund. BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Notes to Financial Statements (continued) Generally, trading in foreign securities, as well as U.S. government securities, money market instruments and certain fixed income securities, is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net asset value of the Fund's shares are determined as of such times. Foreign currency exchange rates will generally be determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Fund's net asset value. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities will be valued at their fair value as determined in good faith by the Fund's Board of Trustees or by the Manager using a pricing service and/or procedures approved by the Fund's Board of Trustees. (b) Derivative financial instruments--The Fund may engage in various portfolio strategies both to increase the return of the Fund and to hedge, or protect, its exposure to interest rate movements and movements in the securities markets. Losses may arise due to changes in the value of the contract due to an unfavorable change in the under-lying security or if the counterparty does not perform under the contract. * Financial futures contracts--The Fund may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Fund as unrealized gains or losses. When the contract is closed, the Fund records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. * Options--The Fund may write and purchase call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. (c) Foreign currency transactions--Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Fund invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Notes to Financial Statements (continued) (e) Recent accounting pronouncements--In July 2006, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting for Uncertainty in Income Taxes - an interpretation of FASB Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity including mutual funds before being measured and recognized in the financial statements. Adoption of FIN 48 is required for the last net asset value calculation in the first required financial statement reporting period for fiscal years beginning after December 15, 2006. The impact on the Fund's financial statements, if any, is currently being assessed. In September 2006, Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"), was issued and is effective for fiscal years beginning after November 15, 2007. FAS 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. At this time, management is evaluating the implications of FAS 157 and its impact on the Fund's financial statements, if any, has not been determined. In addition, in February 2007, FASB issued "Statement of Financial Accounting Standards No. 159, The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), which is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. At this time, management is evaluating the implications of FAS 159 and its impact on the Fund's financial statements, if any, has not been determined. (f) Security transactions and investment income--Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Fund has determined the ex-dividend date. Interest income is recognized on the accrual basis. The Fund amortizes all premiums and discounts on debt securities. (g) Dividends and distributions--Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (h) Securities lending--The Fund may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Fund may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Fund could experience delays and costs in gaining access to the collateral. The Fund also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. 2. Investment Advisory Agreement and Transactions with Affiliates: On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business, Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates, with BlackRock, Inc. to create a new independent company. Merrill Lynch has a 49.8% economic interest and a 45% voting interest in the combined company and The PNC Financial Services Group, Inc. ("PNC"), has approximately a 34% economic and voting interest. The new company operates under the BlackRock name and is governed by a board of directors with a majority of independent members. BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Notes to Financial Statements (continued) The Investment Advisory Agreement between the Fund and the Manager became effective on September 29, 2006. Prior to September 29, 2006, MLIM was the Fund's manager. The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the limited partner. The Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate of BlackRock, Inc. The Manager is responsible for the management of the Fund's portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund pays a monthly fee at the annual rate of .65% of the Fund's average daily net assets. The Manager has entered into a contractual arrangement with the Fund under which the expenses incurred by each class of shares of the Fund (excluding distribution and/or service fees) will not exceed 1.99%. This arrangement has a one-year term and is automatically renewable. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, under which the Manager pays BIM for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Fund to the Manager. Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule 12b-1 under the Investment Company Act of 1940, the Fund pays each Distributor ongoing service and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: Service Distribution Fee Fee Investor A .25% -- Investor B .25% .75% Investor C .25% .75% Pursuant to sub-agreements with each Distributor, broker-dealers, including Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned subsidiary of Merrill Lynch, and each Distributor provide shareholder servicing and distribution services to the Fund. The ongoing service fee compensates the Distributor and each broker-dealer (including MLPF&S) for providing shareholder services to Investor A, Investor B and Investor C shareholders. The ongoing distribution fee compensates each Distributor and MLPF&S for providing shareholder servicing and distribution-related services to Investor B and Investor C shareholders. For the six months ended February 28, 2007, MLPF&S received contingent deferred sales charges of $73,374 and $50 relating to transactions in Investor B and Investor C Shares, respectively. The Trust, on behalf of the Fund, has entered into a Financial Warranty Agreement with Main Place Funding, LLC (the "Warranty Provider"). The Financial Warranty Agreement is intended to ensure that on the Guarantee Maturity Date, each shareholder of the Fund will be entitled to redeem his or her shares for an amount no less than the initial value of that shareholder's account (less expenses and sales charges not covered by the Financial Warranty Agreement), provided that all dividends and distributions received from the Fund have been reinvested and no shares have been redeemed (the "Guaranteed Amount"). The Fund will pay to the Warranty Provider, under the Financial Warranty Agreement, an annual fee equal to .80% of the Fund's average daily net assets during the Guarantee Period. If the value of the Fund's assets on the Guarantee Maturity Date is insufficient to result in the value of each shareholder's account being at least equal to the share-holder's Guaranteed Amount, the Warranty Provider will pay the Fund an amount sufficient to ensure that each shareholder's account can be redeemed for an amount equal to his or her Guaranteed Amount. The Manager maintains a call center, which is responsible for providing certain shareholder services to the Fund, such as responding to shareholder inquiries and processing transactions based upon instructions from shareholders with respect to the subscription and redemption of Fund shares. During the period September 29, 2006 to February 28, 2007, the following amounts have been accrued by the Fund to reimburse the Manager for costs incurred running the call center, which are a component of the transfer agent fees in the accompanying Statement of Operations. BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND FEBRUARY 28, 2007 Notes to Financial Statements (continued) Call Center Fees Institutional $ 20 Investor A $ 39 Investor B $580 Investor C $242 The Fund has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to MLPF&S or its affiliates. Pursuant to that order, the Fund has retained BIM as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. Prior to September 29, 2006, BIM was organized as Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM, and MLIM, LLC was the securities lending agent. BIM may, on behalf of the Fund, invest cash collateral received by the Fund for such loans, among other things, in a private investment company managed by the Manager or its affiliates. In addition, MLPF&S received $12,123 in commissions on the execution of portfolio security transactions for the Fund for the six months ended February 28, 2007. For the six months ended February 28, 2007, the Fund reimbursed MLIM and the Manager $181 and $904, respectively, for certain accounting services. Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Manager, became the Fund's transfer agent. Prior to September 29, 2006, the Fund's transfer agent was Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch. Prior to September 29, 2006, certain officers and/or trustees of the Fund were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or MLIM, LLC. Commencing September 29, 2006, certain officers and/or trustees of the Fund are officers and/or directors of BlackRock, Inc. or its affiliates. 3.

Short-Term Borrowings: The Fund, along with certain other funds managed by the Manager and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders. The Fund may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Fund may borrow up to the maximum amount allowable under the Fund's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. On November 22, 2006, the credit agreement was renewed for one year under substantially the same terms.
