Counterbalancing these difficulties were booming export activity, a robust non-financial corporate sector and, notably, aggressive and timely monetary and fiscal policy actions. Amid the market tumult, the Federal Reserve Board (the "Fed") intervened with a series of moves to bolster liquidity and ensure financial market stability. Since September 2007, the central bank slashed the target federal funds rate 325 basis points (3.25%), bringing the rate to 2.0% as of period-end. Of greater magnitude, however, were the Fed's other policy decisions, which included opening the discount window directly to broker dealers and investment banks and backstopping the unprecedented rescue of Bear Stearns. The Fed's response to the financial crisis helped to improve credit conditions and investor mood. After hitting a low point on March 17 (coinciding with the collapse of Bear Stearns), equity markets found a welcome respite in April, when the S&P 500 Index of U.S. stocks posted positive monthly performance for the first time since October 2007. International markets, which outpaced those of the U.S. for much of 2007, saw a reversal in that trend, as effects of the credit crisis and downward pressures on growth were far-reaching. In contrast to equity markets, Treasury securities rallied (yields fell as prices correspondingly rose), as a broad "flight-to-quality" theme persisted. The yield on 10-year Treasury issues, which touched 5.30% in June 2007 (its highest level in five years), fell to 4.04% by year-end and to 3.77% by April 30. Treasury issues relinquished some of their gains in April, however, as investor appetite for risk returned and other high-quality fixed income sectors outperformed. Problems within the monoline insurance industry and the failure of auctions for auction rate securities plagued the municipal bond market, driving yields higher and prices lower across the curve. However, in conjunction with the more recent shift in sentiment, the sector delivered strong performance in the final month of the reporting period. Overall, the major benchmark indexes generated results that generally reflected heightened investor risk aversion: Total Returns as of April 30, 2008 6-month 12-month ================================================================================================================= U.S. equities (S&P 500 Index) - 9.64% - 4.68% - ----------------------------------------------------------------------------------------------------------------- Small cap U.S. equities (Russell 2000 Index) -12.92 -10.96 - ----------------------------------------------------------------------------------------------------------------- International equities (MSCI Europe, Australasia, Far East Index) - 9.21 - 1.78 - ----------------------------------------------------------------------------------------------------------------- Fixed income (Lehman Brothers U.S. Aggregate Index) + 4.08 + 6.87 - ----------------------------------------------------------------------------------------------------------------- Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) + 1.47 + 2.79 - ----------------------------------------------------------------------------------------------------------------- High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Capped Index) - 0.73 - 0.80 - ----------------------------------------------------------------------------------------------------------------- Past performance is no guarantee of future results.

Throughout the six months, the Fund's equity allocation remained at 100% of net assets and the fixed income allocation at 0%. What factors influenced performance? o Broadly speaking, the Fund's underperformance for the period resulted from both asset allocation and stock selection factors. o Unfavorable asset allocation decisions included overweight positions versus the benchmark in health care and information technology (IT), and an underweight in consumer staples. Our stock picks in health care (mainly health care providers) and IT (especially in semiconductor and software names) had the greatest negative impact on relative returns. Security selection in consumer staples and consumer discretionary (notably hotels and restaurants, specialty retailers and luxury goods providers) also detracted from performance. o An overweight in the energy sector proved advantageous, but was overshadowed by disappointing stock selection among oil and gas names. The underperformance was concentrated among oil refiners, whose profit margins were compressed by higher oil prices. o On the positive side, a significant underweight in financials (particularly capital markets, commercial banks and consumer finance) and an underweight in telecommunication services (primarily in wireless telecommunication services) benefited the Fund's comparative performance for the period. Describe recent portfolio activity. o During the period, we increased the Fund's exposure to the energy and health care sectors. We reduced exposure to the financials and consumer discretionary sectors. o Among our largest purchases were Occidental Petroleum Corp., Texas Instruments, Inc., Best Buy Co., Inc., Biogen Idec, Inc. and The NASDAQ OMX Group, Inc. Our largest sales for the period included Cisco Systems, Inc., American International Group, Inc., Mosaic Co., Southern Copper Corp. and Apollo Group, Inc. Describe Fund positioning at period-end. o On April 30, 2008, the Fund remained 100% invested in equities and was overweight relative to the equity benchmark in IT, health care, energy and consumer discretionary, and underweight in financials, consumer staples, utilities and telecommunication services. o We continue to expect lackluster U.S. economic growth over the next several quarters as counteracting forces prevent both an outright recession and a return to its historical trend or above-trend growth. While inflationary problems do exist in some emerging markets, we expect inflationary pressures in the U.S. to diminish in the months ahead, particularly since the credit squeeze and housing bust are both deflationary forces and the economy continues to operate below its potential. We recognize that economic risks remain and the rally in global equity prices late in the semi-annual period may have advanced to the point at which some additional corrective action could take place. In our view, however, the broad economic, corporate earnings and inflationary backdrop should benefit most market sectors and act as a foundation for improved market conditions, which we believe has already begun to fall into place.

Because the Fund invests significantly in a master portfolio, the expense table example reflects the expenses of both the fund and the master portfolio in which it invests. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year divided by 366.

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/funds 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. Performance data does not reflect this potential fee. Figures shown in the performance tables on page 5 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. 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 expense example on page 4 (which is based on a hypothetical investment of $1,000 invested on November 1, 2007 and held through April 30, 2008) 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 table 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 corresponding to their share class under the heading entitled "Expenses Paid During the Period." The table also 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 hypothetical 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. 6 BLACKROCK CORE PRINCIPAL PROTECTED FUND APRIL 30, 2008 Statement of Assets and Liabilities BlackRock Core Principal Protected Fund April 30, 2008 (Unaudited) =================================================================================================================================== Assets - ----------------------------------------------------------------------------------------------------------------------------------- Investment at value -- Master Large Cap Core Portfolio (the "Portfolio") (cost -- $97,674,350) ................... $ 112,419,837 Prepaid expenses ................................................................................................. 918 ------------- Total assets ..................................................................................................... 112,420,755 ------------- =================================================================================================================================== Liabilities - ----------------------------------------------------------------------------------------------------------------------------------- Distribution fees payable ........................................................................................ 86,081 Financial warranty fees payable .................................................................................. 58,536 Investment advisory fees payable ................................................................................. 27,011 Other affiliates payable ......................................................................................... 17,977 Officer payable .................................................................................................. 60 Other accrued expenses payable ................................................................................... 10,838 ------------- Total liabilities ................................................................................................ 200,503 ------------- =================================================================================================================================== Net Assets - ----------------------------------------------------------------------------------------------------------------------------------- Net Assets ....................................................................................................... $ 112,220,252 ============= =================================================================================================================================== Net Assets Consist of - ----------------------------------------------------------------------------------------------------------------------------------- Paid-in capital, unlimited shares of no par value authorized ..................................................... $ 103,083,654 Accumulated net investment loss ..................................................................................

See Notes to Financial Statements. BLACKROCK CORE PRINCIPAL PROTECTED FUND APRIL 30, 2008 13 Notes to Financial Statements (Unaudited) BlackRock Core Principal Protected Fund 1. Significant Accounting Policies: BlackRock Core Principal Protected Fund (the "Fund") is a series of BlackRock Principal Protected Trust ("the Trust") and is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as a diversified, open-end management investment company. The Fund seeks to achieve its investment objective by investing all or a portion of its assets in Master Large Cap Core Portfolio (the "Portfolio"), which is a series of Master Large Cap Series LLC. The value of the Fund's investment in the Portfolio reflects the Fund's proportionate interest in the net assets of the Portfolio. The performance of the Fund is directly affected by the performance of the Portfolio. The financial statements of the Portfolio, including the Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund's financial statements. The Fund's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The percentage of the Portfolio owned by the Fund at April 30, 2008 was 2.5%. 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 February 28, 2003 through February 28, 2010 (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. Institutional Shares are sold without a sales charge and only to certain eligible investors. Investor A Shares are generally sold with a front-end sales charge. Investor B and Investor C Shares 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 material changes to the Investor A distribution plan). The following is a summary of significant accounting policies followed by the Fund: Valuation of Investments: The Fund records its investment in the Portfolio at fair value. Valuation of securities held by the Portfolio is discussed in Note 1 of the Portfolio's Notes to Financial Statements, which are included elsewhere in this report. Investment Transactions and Net Investment Income: Investment transactions in the Portfolio are accounted for on a trade date basis. The Fund records daily its proportionate share of the Portfolio's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own expenses. Income and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets. Dividends and Distributions to Shareholders: Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. 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. Effective April 30, 2008, the Fund implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including investment companies, before being measured and recognized in the financial statements. The advisor has evaluated the application of FIN 48 to the Fund, and has determined that the adoption of FIN 48 does not have a material impact on the Fund's financial statements. The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund's U.S. federal tax returns remains open for the years ended October 31, 2004 through October 31, 2006.The statutes of limitations on the Fund's state and local tax returns may remain open for an additional year depending upon the jurisdiction. Recent Accounting Pronouncements: 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. The impact on the Fund's financial statement disclosures, if any, is currently being assessed. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007 provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Fund's financial statement disclosures, if any, is currently being assessed. 14 BLACKROCK CORE PRINCIPAL PROTECTED FUND APRIL 30, 2008 Notes to Financial Statements (continued) BlackRock Core Principal Protected Fund In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities -- an amendment of FASB Statement No. 133" ("FAS 161"), was issued and is effective for fiscal years beginning after November 15, 2008. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity's results of operations and financial position. The advisor is currently evaluating the implications of FAS 161 and the impact on the Fund's financial statement disclosures, if any, is currently being assessed. Other: Expenses directly related to the Fund or its classes are charged to that Fund or class. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods. Other expenses of the Fund are allocated daily to each class based on its relative net assets. 2. Investment Advisory Agreement and Other Transactions with Affiliates: The Trust, on behalf of the Fund, has entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment advisory and administrative services. For such services, the Fund pays a monthly fee at an annual rate of 0.75% of the Fund's average daily net assets. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are principal owners of BlackRock, Inc. The Advisor has contractually agreed to waive its advisory fee by the amount of investment advisory fees the Fund pays the Advisor indirectly through its investment in the Portfolio. For the six months ended April 30, 2008, the Advisor earned fees of $490,370, of which $300,824 was waived. This amount is shown on the Statement of Operations as fees waived by the Advisor. In addition, the Advisor 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 renewable. For the six months ended April 30, 2008, the Fund reimbursed the Advisor $1,000 for certain accounting services, which are included in accounting services in the Statement of Operations. In addition, the Advisor has entered into a separate sub-advisory agreement with BlackRock Investment Management, LLC ("BIM"), an affiliate of the Advisor, under which the Advisor pays BIM, for services it provides, a monthly fee that is a percentage of the investment advisory fee paid by the Fund to the Advisor. The Fund has also entered into separate Distribution Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock Distributors, Inc. and its affiliates ("BDI") (collectively, the "Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group, Inc., and BDI is an affiliate of BlackRock, Inc. Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule 12b-1 under the 1940 Act, the Fund pays the Distributor ongoing service and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the shares as follows: - -------------------------------------------------------------------------------- Service Distribution Fee Fee - -------------------------------------------------------------------------------- Investor A .................................. 0.25% -- Investor B .................................. 0.25% 0.75% Investor C .................................. 0.25% 0.75% - -------------------------------------------------------------------------------- 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 and/or distribution fee compensates the Distributor and each broker-dealer for providing shareholder servicing and/or distribution related services to Investor A, Investor B and Investor C shareholders. For the six months ended April 30, 2008, affiliates received contingent deferred sales charges of $80,274 and $792 relating to transactions in Investor B and Investor C Shares, respectively. The Advisor 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 six months ended April 30, 2008, the following amounts have been accrued by the Fund to reimburse the Advisor for costs incurred running the call center, which are a component of the transfer agent fees in the accompanying Statement of Operations. - -------------------------------------------------------------------------------- Call Center Fees - -------------------------------------------------------------------------------- Institutional .................................................. $ 48 Investor A ..................................................... $ 133 Investor B ..................................................... $1,098 Investor C ..................................................... $ 708 BLACKROCK CORE PRINCIPAL PROTECTED FUND APRIL 30, 2008 15 Notes to Financial Statements (concluded) BlackRock Core Principal Protected Fund The Trust, on behalf of the Fund, and the Advisor have entered into a Financial Guarantee Agreement with Ambac Assurance Corporation ("Ambac"). The Financial Guarantee Agreement is intended to make sure that on the Guaranteed 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 Guarantee 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 Ambac, under the Financial Guarantee Agreement, an annual fee equal to .625% of the Fund's average daily net assets during the Guarantee Period. If the value of the Fund's assets on the Guaranteed Maturity Date is insufficient to result in the value of each shareholder's account being at least equal to the shareholder's Guaranteed Amount, Ambac will pay the Fund an amount sufficient to make sure that each shareholder's account can be redeemed for an amount equal to each shareholder's Guaranteed Amount. PFPC Inc., an indirect, wholly owned subsidiary of PNC and an affiliate of the Advisor, serves as transfer agent. Each class of the Fund bears the costs of transfer agent fees associated with such respective classes. Transfer agency fees borne by each class of the Fund are comprised of those fees charged for all shareholder communications including shareholder reports, dividend and distribution notices, and proxy materials for shareholders meetings, as well as per account and per transaction fees related to servicing and maintenance of shareholder accounts, including the issuing, redeeming and transferring of shares of each class of the Fund, 12b-1 fee calculation, check writing, anti-money laundering services, and customer identification services. Certain officers and/or trustees of the Trust are officers and/or trustees of BlackRock, Inc. or its affiliates. 3.

See Notes to Financial Statements. 24 BLACKROCK CORE PRINCIPAL PROTECTED FUND APRIL 30, 2008 Notes to Financial Statements (Unaudited) Master Large Cap Core Portfolio 1. Significant Accounting Policies: Master Large Cap Core Portfolio (the "Portfolio") is a series of Master Large Cap Series LLC (the "Master LLC"). The Master LLC is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), and is organized as a Delaware limited liability company. The Limited Liability Company Agreement permits the Directors to issue non-transferable interests in the Master LLC, subject to certain limitations. The Portfolio's financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Portfolio: Valuation of Investments: Equity investments traded on a recognized securities exchange or the NASDAQ Global Market System are valued at the last reported sale price that day or the NASDAQ official closing price, if applicable. Equity investments traded on a recognized exchange for which there were no sales on that day are valued at the last available bid price. Investments in open-end investment companies are valued at net asset value each business day. In the event that application of these methods of valuation results in a price for an investment which is deemed not to be representative of the market value of such investment, the investment will be valued by a method approved by the Board of Directors (the "Board") as reflecting fair value ("Fair Value Assets"). When determining the price for Fair Value Assets, the investment advisor and/or sub-advisor seeks to determine the price that the Portfolio might reasonably expect to receive from the current sale of that asset in an arm's-length transaction. Fair value determinations shall be based upon all available factors that the investment advisor and/or sub-advisor deems relevant. The pricing of all Fair Value Assets is subsequently reported to the Board or a committee thereof. Investment Transactions and Investment Income: Investment 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 Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. Securities Lending: The Portfolio 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 Portfolio and any additional required collateral is delivered to the Portfolio on the next business day. The Portfolio typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Portfolio 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 the standard time period for settlement of securities transactions. The Portfolio may pay reasonable 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 Portfolio could experience delays and costs in gaining access to the collateral. The Portfolio 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. Income Taxes: It is the Portfolio'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 laws, a withholding tax may be imposed on interest, dividends and capital gains at various rates. Effective April 30, 2008, the Portfolio implemented Financial Accounting Standards Board ("FASB") Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109" ("FIN 48"). FIN 48 prescribes the minimum recognition threshold a tax position must meet in connection with accounting for uncertainties in income tax positions taken or expected to be taken by an entity, including investment companies, before being measured and recognized in the financial statements. The investment advisor has evaluated the application of FIN 48 to the Portfolio and has determined that the adoption of FIN 48 does not have a material impact on the Portfolio's financial statements. The Portfolio files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Portfolio's U.S. federal tax returns remains open for the years ended October 31, 2004 through October 31, 2006. The statutes of limitations on the Portfolio's state and local tax returns may remain open for an additional year depending upon the jurisdiction. BLACKROCK CORE PRINCIPAL PROTECTED FUND APRIL 30, 2008 25 Notes to Financial Statements (continued) Master Large Cap Core Portfolio Recent Accounting Pronouncements: 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. The impact on the Portfolio's financial statement disclosures, if any, is currently being assessed. In addition, in February 2007, Statement of Financial Accounting Standards No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("FAS 159"), was issued and is effective for fiscal years beginning after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of FAS 157. FAS 159 permits entities to choose to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. FAS 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between entities that choose different measurement attributes for similar types of assets and liabilities. The impact on the Portfolio's financial statement disclosures, if any, is currently being assessed. In March 2008, Statement of Financial Accounting Standards No. 161, "Disclosures about Derivative Instruments and Hedging Activities -- an amendment of FASB Statement No. 133" ("FAS 161"), was issued and is effective for fiscal years beginning after November 15, 2008. FAS 161 is intended to improve financial reporting for derivative instruments by requiring enhanced disclosure that enables investors to understand how and why an entity uses derivatives, how derivatives are accounted for, and how derivative instruments affect an entity's results of operations and financial position. The investment advisor is currently evaluating the implications of FAS 161 and the impact on the Portfolio's financial statement disclosures, if any, is currently being assessed. Bank Overdraft: The Portfolio recorded a bank overdraft, which resulted from management estimates of available cash. Other: Expenses directly related to the Portfolio are charged to the Portfolio. Other operating expenses shared by several funds are pro-rated among those funds on the basis of relative net assets or other appropriate methods. 2. Investment Advisory Agreement and Other Transactions with Affiliates: The Master LLC, on behalf of the Portfolio, has entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the "Advisor"), an indirect, wholly owned subsidiary of BlackRock, Inc., to provide investment advisory and administration services. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. are principal owners of BlackRock, Inc.
