Burke, Chief Executive Officer, Master Core Bond Enhanced Index Series of Quantitative Master Series LLC, 800 Scudders Mill Road, Plainsboro, NJ, 08536. Mailing address: P.O. Box 9011, Princeton, NJ, 08543-9011 Registrant's telephone number, including area code: (800) 441-7762 Date of fiscal year end: 12/31/2007 Date of reporting period: 01/01/2007 - 12/31/2007 Item 1 - Report to Stockholders Master Core Bond Enhanced Index Series of Quantitative Master Series LLC Annual Report, December 31, 2007 PORTFOLIO MANAGEMENT COMMENTARY How did the Series perform? o Master Core Bond Enhanced Index Series (the "Series) modestly underperformed the benchmark Lehman Brothers U.S. Aggregate Bond Index for the fiscal year as the Series had a total return of +6.83% compared to +6.97% for the Index. What factors influenced performance? o One of the largest detractors from performance was our overweight to high-quality spread assets, particularly AAA-rated commercial mortgage-backed securities (CMBS), as well as agency mortgage pass-throughs, asset-backed securities (ABS) and other mortgage-related products. Despite their high quality, these assets suffered amid fallout from the subprime mortgage scare. Generalized concerns over the mortgage market, coupled with lack of liquidity and the liquidation by investors of all mortgage-related assets, caused the underperformance. o On the positive side, an underweight exposure to corporate bonds, and successful security selection within the corporate sector, benefited the portfolio's relative performance. In addition, we had positioned the portfolio for a steepening yield curve in the second half of the year, a move that proved advantageous as short-term interest rates fell more than long-term interest rates, causing the curve to steepen. An underweight in agency debentures benefited performance as well. Describe recent portfolio activity. o As spread sectors underperformed across the fixed income markets, we used this as an opportunity to increase exposure to high-quality mortgage products, moving from an underweight position in mortgages at the start of 2007 to a significant overweight by year-end. In addition, during late third quarter-early fourth quarter, we started to decrease our underweight to investment-grade corporate bonds as the valuations of lower-quality assets began to appear more attractive. o We maintained the yield curve steepening bias, but kept duration relatively close to that of the index. Describe portfolio positioning at period-end. o At year-end, the portfolio was underweight in U.S. Treasury issues, U.S. agency securities and corporate securities, although we closed the gap in the corporate sector somewhat. The portfolio maintained its notable overweights in high-quality, short-duration spread product, including mortgage pass-through securities, CMBS and ABS. In general, we find high-quality spread-related assets to be an attractive investment, offering yields beyond those provided by Treasury securities alone but without the risk associated with corporate bonds. Although some areas of the corporate market are attractive, lingering concerns about the economy cause us to be less positive on corporate credit overall. 1 Master Core Bond Enhanced Index Series Portfolio Information as of December 31, 2007 -

Significant Accounting Policies: Master Core Bond Enhanced Index Series (formerly Master Aggregate Bond Index Series) (the "Series"), a non-diversified management investment company, is part of Quantitative Master Series LLC (the "Master LLC"). The Master LLC is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware limited liability company. Prior to June 15, 2007, the Master LLC was organized as a Delaware statutory trust (the "Trust"). The Limited Liability Company Agreement permits the Directors (and prior to June 15, 2007, the Declaration of Trust permitted the Trustees) to issue non-transferable interests, subject to certain limitations. Throughout this report, the Trust and the Master LLC are referred to as the Master LLC and the Board of Trustees of the Trust and the Board of Directors of the Master LLC are referred to as the Board of Directors. The financial statements of the Series are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. All such adjustments are of a normal, recurring nature. The following is a summary of significant accounting policies followed by the Series. (a)Valuation of investments - Debt securities are traded primarily in the over-the-counter ("OTC") markets and are valued at the last available bid price in the OTC market or on the basis of values obtained by a pricing service. Pricing services use valuation matrixes that incorporate both dealer supplied valuations and valuation models. The procedures of the pricing service and its valuations are reviewed by the officers of the Master LLC under the general direction of the Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Options written or purchased are valued at the last sale price in the case of exchange-traded options. Effective September 4, 2007, exchange-traded options are valued at the mean between the last bid and asked prices at the close of the options market in which the options trade and previously were valued at the last sales price as of the close of options trading on applicable exchanges. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements are valued based upon quoted fair valuations received daily by the Series from a pricing service or counterparty. Effective April 2, 2007, short-term investments are valued at amortized cost, which approximates market value. Prior to April 2, 2007, portfolio securities with remaining maturities of greater than 60 days, for which market quotations were readily available, were valued at market value. As securities transitioned from 61 to 60 days to maturity, the difference between the valuation existing on the sixty-first day before maturity and maturity value was amortized on a straight-line basis to maturity. Repurchase agreements are valued at cost plus accrued interest. Investments in open-end investment companies are valued at their net asset value each business day. Securities and other 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 Directors. Equity securities held by the Series that are traded on stock exchanges or the NASDAQ Global Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Directors. Long positions traded in the OTC markets, NASDAQ Capital Market or Bulletin Board are valued at the last available bid price obtained from one or more dealers or pricing services approved by the Board of Directors. Short positions traded in the OTC markets are valued at the last available asked price. Portfolio securities that are traded both in the OTC markets and on a stock exchange are valued according to the broadest and most representative market. 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 value of such securities used in computing the net assets of the Series are determined as of such times. Foreign currency exchange rates will generally be determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Series' net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities will be valued at their fair value as determined in good faith by the Board of Directors or by BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., using a pricing service and/or procedures approved by the Board of Directors. 18 (b) Derivative financial instruments - The Series may engage in various portfolio investment techniques to provide liquidity or as a proxy for a direct investment in securities underlying the Series' index. Losses may arise due to changes in the value of the contract due to an unfavorable change in the price of the underlying security or index, or if the counterparty does not perform under the contract. The counterparty, for certain instruments, may pledge cash or securities as collateral. o Financial futures contracts - The Series may purchase or sell financial futures contracts and options on such financial futures contracts. Financial futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Series deposits, and maintains as collateral, such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in the value of the contract. Such receipts or payments are known as variation margin and are recorded by the Series as unrealized gains or losses. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Options - The Series may purchase and write call and put options. When the Series writes an option, an amount equal to the premium received by the Series is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Series enters into a closing transaction), the Series realizes a gain or loss on the option to the extent of the premiums received or paid (or a gain or loss to the extent that the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. o Swaps - The Series may enter into swap agreements, which are OTC contracts in which the Series and a counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Series are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. (c) Reverse repurchase agreements - The Series may enter into reverse repurchase agreements. Under reverse repurchase agreements, the Series sells securities to the counterparty and agrees to repurchase them at a mutually agreed upon date and price, and may exchange their respective commitments to pay or receive interest. If the counterparty defaults on its obligation, the Series' ability to receive interest will be delayed or limited. Furthermore, if the Series does not have sufficient client income to pay its obligation under the reverse repurchase agreement, the Series would be in default and the counterparty would be able to terminate the repurchase agreement. At the time the Series enters into a reverse repurchase agreement, it will establish a segregated account with the custodian containing cash, or cash equivalents of liquid high grade debt securities having a value at least equal to the repurchase price. (d) Income taxes - The Series is classified as a partnership for federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. Therefore, no federal income tax provision is required. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of Subchapter M of the Internal Revenue Code. (e) Security transactions and investment income - Security transactions are accounted for on the date the securities are purchased or sold (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Interest income is recognized on the accrual basis. The Series amortizes all premiums and discounts on debt securities. 19 (f) Dollar rolls - The Series may sell securities for delivery in the current month and simultaneously contract to repurchase substantially similar (same type, coupon and maturity) securities on a specific future date. The Series receives compensation as consideration for entering into the commitment to repurchase. The Series must maintain liquid securities having a value not less than the repurchase price (including accrued interest) for such dollar rolls. The market value of the securities that the Series is required to purchase may decline below the agreed upon repurchase price of those securities. (g) Securities lending - The Series 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 Series and any additional required collateral is delivered to the Series on the next business day. Where the Series receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Series typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Series receives cash collateral, it may invest such collateral and retain the amount earned on such investments, 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 Series 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 Series could experience delays and costs in gaining access to the collateral. The Series 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. (h) TBA commitments - The Series may enter into to be announced ("TBA") commitments to purchase or sell securities for a fixed price at a future date. TBA commitments are considered securities in themselves, and involve a risk of loss if the value of the security to be purchased/sold declines/increases prior to settlement date, which is in addition to the risk of decline in the value of the Series' other assets. Unsettled TBA commitments are valued at the current market value of the underlying securities, according to the procedures described under "Valuation of investments." (i) Asset-backed securities -- The Series invests a significant portion of its assets in securities backed by commercial or residential mortgage loans or in issuers that hold mortgage and other asset-backed securities. Please see the Schedule of Investments for these securities. Changes in economic conditions, including delinquencies and/or defaults or assets underlying these securities, can affect the value, income and/or liquidity of such positions. (j) Recent accounting pronouncements - Effective June 29, 2007, the Series 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. Management has evaluated the application of FIN 48 to the Series, and has determined that the adoption of FIN 48 does not have a material impact on the Series' financial statements. The Series 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 Series' U.S. federal tax returns remains open for the years ended December 31, 2004 through December 31, 2006. The statute of limitations on the Series' state and local tax returns may remain open for an additional year depending upon the jurisdiction. 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 Series' 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 Series' financial statement disclosures, if any, is currently being assessed. 20 2. Investment Advisory Agreement and Transactions with Affiliates: The Master LLC, on behalf of the Series, has entered into an Investment Advisory Agreement with the Manager. Merrill Lynch & Co., Inc ("Merrill Lynch") and The PNC Financial Services Group, Inc. are the principal owners of BlackRock, Inc. The Manager is responsible for the management of the Series' portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Series pays a monthly fee at an annual rate of .01% of the average daily value of the Series' net assets. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Financial Management, Inc. ("BFM"), an affiliate of the Manager, under which the Manager pays BFM for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Series to the Manager. Prior to July 18, 2007, Merrill Lynch Trust Company, a wholly owned subsidiary of Merrill Lynch, was the Series' custodian. Effective July 18, 2007, State Street Bank & Trust Co. became the Series' custodian. The Master LLC, on behalf of the Series, has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated, a wholly owned subsidiary of Merrill Lynch, or its affiliates. Pursuant to that order, the Master LLC has retained BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. BIM may, on behalf of the Master LLC and the Series, invest cash collateral received by the Series for such loans, among other things, in a private investment fund managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended December 31, 2007 there were no securities lending agent fees paid to BIM. For the year ended December 31, 2007, the Series reimbursed the Manager $8,004 for certain accounting services. Certain officers and/or directors of the Master LLC are officers and/or directors of BlackRock, Inc. or its affiliates. 3. Investments: Purchases and sales (including paydowns) of investments, excluding short-term securities and dollar rolls, for the year ended December 31, 2007 were $995,906,371 and $1,443,459,393, respectively. Transactions in call options written for the year ended December 31, 2007 were as follows: - -------------------------------------------------------------------------------- Number of Contracts+ Premiums Received - -------------------------------------------------------------------------------- Outstanding call options written, beginning of year 13 $ 85,760 Options written 37 21,110 Options expired (13) (85,760) ===== ========= Outstanding call options written, end of year 37 $ 21,110 ===== ========= + One contract represents a notional amount of $1,000,000.

Short-Term Borrowings: The Master LLC, on behalf of the Series, along with certain other funds managed by the Manager and its affiliates, is party to a $500,000,000 credit agreement with a group of lenders. The Series may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series' current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Series pays a commitment fee of .06% per annum based on the Series' pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each fund's election, the federal funds rate plus .35% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the year ended December 31, 2007. On November 21, 2007, the credit agreement was renewed for one year under substantially the same terms. 22 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Investors and Board of Directors of Quantitative Master Series LLC: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Core Bond Enhanced Index Series (formerly Master Aggregate Bond Index Series), one of the portfolios constituting Quantitative Master Series LLC (formerly Quantitative Master Series Trust) (the "Master LLC"), as of December 31, 2007, and the related statement of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Master LLC's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. The Master LLC is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Master LLC's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2007, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Master Core Bond Enhanced Index Series of Quantitative Master Series LLC as of December 31, 2007, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America.

(e)(1) Audit Committee Pre-Approval Policies and Procedures: The registrant's audit committee (the "Committee") has adopted policies and procedures with regard to the pre-approval of services. Audit, audit-related and tax compliance services provided to the registrant on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrant and those non-audit services provided to the registrant's affiliated service providers that relate directly to the operations and the financial reporting of the registrant. Certain of these non-audit services that the Committee believes are a) consistent with the SEC's auditor independence rules and b) routine and recurring services that will not impair the independence of the independent accountants may be approved by the Committee without consideration on a specific case-by-case basis ("general pre-approval"). However, such services will only be deemed pre-approved provided that any individual project does not exceed $5,000 attributable to the registrant or $50,000 for all of the registrants the Committee oversees. Any proposed services exceeding the pre-approved cost levels will require specific pre-approval by the Committee, as will any other services not subject to general pre-approval (e.g., unanticipated but permissible services). The Committee is informed of each service approved subject to general pre-approval at the next regularly scheduled in-person board meeting. (e)(2) None of the services described in each of Items 4(b) through (d) were approved by the audit committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.
