SEPTEMBER 30, 2007 A Letter to Shareholders Dear Shareholder The September reporting period took financial markets on a wild ride. While subprime mortgage woes dominated headlines for much of 2007, troubles intensified in the final months of the period, spawning a widespread "credit crunch" that crept into other areas of the market. The U.S. Federal Reserve Board (the "Fed") and other countries' central banks stepped in to inject liquidity into the markets and bolster investor confidence. The Fed cut the discount rate, the rate banks pay to borrow money directly from the Fed, from 6.25% to 5.25% in two moves in August and September. The central bankers also cut the more widely followed federal funds target rate, which had remained unchanged at 5.25% for over a year, to 4.75% in September. After a tumultuous summer, the dust began to settle toward period-end amid speculation that the worst of the credit crunch had passed. Although heightened volatility and a weakening U.S. economy have been recurring themes throughout the past year, equity markets have displayed surprising resilience. Most recently, the credit turmoil dampened corporate merger-and-acquisition activity, a key source of strength for equity markets. However, market fundamentals have held firm, dividend payouts and share buybacks have continued to grow, and valuations remain attractive. These tailwinds generally have prevailed over the headwinds created by the slowing U.S. economy and troubled housing market. In fixed income markets, mixed economic signals and the credit market debacle resulted in a flight to quality. At the height of the uncertainty, investors shunned bonds associated with the housing and credit markets in favor of higher-quality Treasury issues. The yield on 10-year Treasury issues, which touched 5.30% in June (its highest level in five years), fell to 4.59% by period-end, while prices correspondingly rose. Against this backdrop, financial markets posted generally positive results for the six-month period, and relatively stronger returns for the full year ended September 30, 2007: Total Returns as of September 30, 2007 6-month 12-month U.S. equities (S&P 500 Index) +8.44% +16.44% Small cap U.S. equities (Russell 2000 Index) +1.19 +12.34 International equities (MSCI Europe, Australasia, Far East Index) +8.72 +24.86 Fixed income (Lehman Brothers U.S. Aggregate Bond Index) +2.31 + 5.14 Tax-exempt fixed income (Lehman Brothers Municipal Bond Index) +1.15 + 3.10 High yield bonds (Lehman Brothers U.S. Corporate High Yield 2% Issuer Cap Index) +0.56 + 7.62 Past performance is no guarantee of future results. Index performance shown for illustrative purposes only. You cannot invest directly in an index. As you navigate market volatility, we encourage you to review your investment goals with your financial professional and to make portfolio changes, as needed.

THIS PAGE NOT PART OF YOUR FUND REPORT Fund Summary Portfolio Management Commentary The Fund was formerly known as BlackRock Bond Fund. How did the Fund perform? * The Fund's total return lagged that of its benchmark for the period. What factors influenced performance? * The first eight months of the fiscal year were relatively uneventful in comparison to the final four. Bond yields rose sharply (and prices fell) in early June, with the 10-year Treasury yield touching 5.33%, its highest level since 2001. This was largely based on stronger-than-expected economic readings, which led investors to believe that the Federal Reserve Board (the "Fed") would keep short-term interest rates on hold for some time. Just weeks later, perceptions changed dramatically amid escalating troubles in the subprime mortgage market. * Financial markets were highly volatile as fears spread about which investments might have exposure to the subprime segment. The liquidity of mortgage-backed securities began drying up, which led to a wider liquidity crisis as banks restricted their short-term lending. The Fed and other countries' central banks stepped in to inject liquidity into the markets and bolster investor confidence. The Fed cut the discount rate from 6.25% to 5.25% and the federal funds rate from 5.25% to 4.75% in an effort to offset deteriorating credit conditions in the housing market and help prevent any negative spillover in the economy. * Spread sectors (mortgage-backed securities, commercial MBS, investment- grade corporate bonds, asset-backed securities and U.S. agency issues), which had outperformed Treasury issues in the first half of the fiscal year, lost ground in the latter half as investors fled to the perceived safety of Treasury issues. * Detracting from Fund performance was our overweight exposure to mortgage pass-through securities and commercial mortgages. Although their performance lagged amid the subprime turmoil, we believe these securities were unduly punished and are positioned to perform well as the markets heal. Our allocation to global bonds also hampered relative performance. * Benefiting Fund results was our underweighting of corporate and agency bonds, which also suffered amid the recent credit crunch. Favorable bond security selection also was a positive contributor, as was our opportunistic allocation to the high yield and emerging markets sectors. Describe recent portfolio activity. * We continued to emphasize high-quality, short-duration assets. We increased our overall allocation to high-quality bonds in the residential and commercial mortgage markets as spreads widened in these sectors. * The Portfolio remained underweight relative to its benchmark in corporate bonds throughout the year. However, we closed the gap somewhat in the second half by adding to investment grade corporate debt in both the new- issue and secondary market. Describe the Portfolio's positioning at period-end. * The Portfolio's duration (a measure of interest rate sensitivity) was modestly short relative to its benchmark. We also had a small yield curve steepening bias, reflecting our view that the relatively flat yield curve will return to a more normal slope in time. * The Portfolio maintains large overweight positions in residential and commercial mortgages. Fundamentally, we believe current valuations for mortgages are very attractive. We remained underweight in the investment grade corporate and agency markets. From a sector perspective, we are overweight in financials and underweight in industrials, utilities and non- corporate sectors. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 About Fund Performance (concluded) 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 performance tables on page 5 assume reinvestment of all dividends and capital gain distributions, if any, at net asset value on the payable 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. The Fund's Manager waived a portion of its fee. Without such waiver, the Fund's performance would have been lower. 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 8 (which is based on a hypothetical investment of $1,000 invested on April 1, 2007 and held through September 30, 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 table on page 8 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 Ended September 30, 2007." 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 table on the right 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. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC.

Currently, Investor B2 does not accrue distribution fees (12b-1 fees) due to regulatory fee limits. If, during the period, the distribution fees were accrued, the actual expense ratio would have been approximately 1.63%; the actual expenses paid would have been approximately $8.20; and the hypothetical expenses paid would have been approximately $8.20. ** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in the most recent fiscal half year for BlackRock, Service, Investor B2, Investor C and Class R Shares and the actual days since inception for Institutional, Investor A, Investor A1, Investor B, Investor B1, Investor C1 and Investor C2 divided by 365. ++ April 1, 2007 for BlackRock, Service, Investor B2, Investor C and Class R Shares and September 24, 2007 (commencement of operations) for Institutional, Investor A, Investor A1, Investor B, Investor B1, Investor C1 and Investor C2. ++++ The period represents the six months ended for BlackRock, Service, Investor B2, Investor C and Class R Shares and from September 24, 2007 (commencement of operations) for Institutional, Investor A, Investor A1, Investor B, Investor B1, Investor C1 and Investor C2.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements BlackRock Total Return Fund 1. Significant Accounting Policies: BlackRock Total Return Fund (the "Fund"), formerly BlackRock Bond Fund, is a series of BlackRock Bond Fund, Inc. (the "Bond Fund"). The Fund is registered under the Investment Company Act of 1940, as amended, as a diversified, open- end management investment company. The Fund seeks to achieve its investment objective by investing all of its assets in Master Total Return Portfolio (formerly "Master Bond Portfolio") (the "Master Portfolio"), of Master Bond LLC ("Master LLC"), a mutual fund that has the same investment objective and strategies as the Fund. The value of the Fund's investment in the Master Portfolio reflects the Fund's proportionate interest in the net assets of the Master Portfolio. The performance of the Fund is directly affected by the performance of the Master Portfolio. The financial statements of the Master 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 U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The percentage of the Master Portfolio owned by the Fund at September 30, 2007 was 76.2%. On September 24, 2007, the Fund acquired substantially all of the assets and assumed substantially all of the liabilities of BlackRock Total Return Portfolio ("Total Return Portfolio"), a portfolio of BlackRock Funds II. The Fund is the surviving entity in the Reorganization, however, Total Return Portfolio is the accounting survivor. As a result, the Fund assumed the performance and accounting history of Total Return Portfolio at the closing of the Reorganization. The Fund's net assets as of September 24, 2007 of $2,538,462,638, including $6,028,458 of net unrealized depreciation, were combined with those of the Total Return Portfolio. The aggregate net assets immediately after the acquisition amounted to $3,034,201,488. Also on September 24, 2007, all of the portfolio securities held by the Fund were subsequently contributed to the Master Portfolio in exchange for an investment in the Master Portfolio. The Fund offers multiple classes of shares. On September 24, 2007, pursuant to the Reorganization, Investor A Shares of the Total Return Portfolio converted to Service Shares, Investor B Shares of the Total Return Portfolio converted to Investor B2 Shares, Institutional Shares of the Total Return Portfolio converted to BlackRock Shares and Investor C Shares and Class R Shares of Total Return Portfolio received Investor C Shares and Class R Shares of the Fund, respectively. Also, effective September 24, 2007, Institutional, Investor A, Investor A1, Investor B, Investor B1, Investor C1 and Investor C2 Shares commenced operations. Institutional and Service Shares are sold without a sales charge and only to certain eligible investors. Investor A and Investor A1 Shares are sold with a front-end sales charge. Investor B, Investor B1, Investor B2, Investor C, Investor C1 and Investor C2 Shares are subject to a contingent deferred sales charge and also bear certain expenses related to the distribution of such shares. In addition, Investor A1, Investor B, Investor B1, Investor B2, Investor C1 and Investor C2 Shares are sold only to certain eligible investors. Class R Shares commenced operations on October 2, 2006 and are sold only to certain retirement plans. The acquisition was accomplished by a tax-free exchange. In addition, on October 16, 2006, the Fund acquired all of the net assets of BlackRock Intermediate Term Fund of the Bond Fund pursuant to a plan of reorganization. The acquisition was accomplished by a tax-free exchange. All classes of shares have identical voting, dividend, liquidation and other rights and the same terms and conditions, except that Service, Investor A, Investor A1, Investor B, Investor B1, Investor B2, Investor C, Investor C1, Investor C2 and Class R Shares bear certain expenses related to the shareholder servicing of such shares and Investor B, Investor B1, Investor B2, Investor C, Investor C1, Investor C2 and Class R 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, Investor B1 and Investor B2 shareholders may vote on certain changes to the Investor A and Investor A1 distribution plans as applicable). 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--The Fund records its investment in the Master Portfolio at fair value. Valuation of securities held by the Master Portfolio is discussed in Note 1(a) of the Master Portfolio's Notes to Financial Statements, which is included elsewhere in this report. Prior to September 24, 2007, debt securities were traded primarily in the over- the-counter ("OTC") markets and were 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 were reviewed by the officers of the Fund under the general direction of the Board of Directors. Such valuations and procedures were reviewed periodically by the Board of Directors of the Fund. Financial futures contracts and options thereon, which were traded on exchanges, were valued at their closing prices as of the close of such exchanges. Effective September 4, 2007, exchange traded options were valued at the mean price and previously were valued at the last sale price. Options traded in the OTC market were valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements were valued based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Valuations of short-term investment vehicles were generally based on the net asset value of the underlying investment vehicle or amortized cost. Investments in open-end investment companies were valued at their net asset value each business day. Securities and other assets for which market quotations were not readily available were valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements (continued) BlackRock Total Return Fund Generally, trading in foreign securities was substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Fund were determined as of such times. Foreign currency exchange rates were generally determined as of the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates could occur between the times at which they were determined and the close of business on the NYSE that may not have been reflected in the computation of the Fund's net assets. If events (for example, a company announcement, market volatility or a natural disaster) occurred during such periods that were expected to materially affect the value of such securities, those securities might be valued at their fair value as determined in good faith by the Fund's 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 in accordance with a valuation policy approved by the Fund's Board of Directors. (b) Derivative financial instruments--Prior to September 24, 2007, the Fund directly engaged in various portfolio investment 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 could have arisen due to changes in the value of the contract due to an unfavorable change in the price of the underlying security or if the counterparty did not perform under the contract. The counterparty for certain instruments might have pledged cash or securities as collateral. * Financial futures contracts--Prior to September 24, 2007, the Fund purchased and sold 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 deposited and maintained as collateral such initial margin as required by the exchange on which the transaction was effected. Pursuant to the contract, the Fund agreed 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 were recorded by the Fund as unrealized gains or losses. When the contract was closed, the Fund recorded 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--Prior to September 24, 2007, the Fund purchased and wrote call and put options. When the Fund wrote an option, an amount equal to the premium received by the Fund was reflected as an asset and an equivalent liability. The amount of the liability was subsequently marked-to-market to reflect the current market value of the option written. When a security was purchased or sold through an exercise of an option, the related premium paid (or received) was 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 entered into a closing transaction), the Fund realized 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 exceeded the premium paid or received). * Written and purchased options are non-income producing investments. * Forward foreign exchange contracts--Prior to September 24, 2007, the Fund entered into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract was marked-to- market daily and the change in market value was recorded by the Fund as an unrealized gain or loss. When the contract was closed, the Fund recorded a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. * Foreign currency options and futures--Prior to September 24, 2007, the Fund purchased or sold listed or OTC foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions might have been effected with respect to hedges on non-U.S. dollar-denominated securities owned by the Fund, sold by the Fund but not yet delivered, or committed or anticipated to be purchased by the Fund. * Swaps--Prior to September 24, 2007, the Fund entered into swap agreements, which are OTC contracts in which the Fund 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 Fund were recorded in the accompanying Statement of Operations as realized gains or losses, respectively. Gains or losses were also realized upon termination of the swap agreements. Swaps were marked-to-market daily and changes in value were 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. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements (continued) BlackRock Total Return Fund (c) Foreign currency transactions--Prior to September 24, 2007, transactions denominated in foreign currencies were recorded at the exchange rate prevailing when recognized. Foreign currency transactions were 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 included the effects of foreign exchange rates on investments. Foreign securities may have involved a number of risk factors and special considerations not presented with investments in securities of U.S. corporations. (d) Security transactions, investment income and expenses--Security transactions in the Master Portfolio and the Fund (prior to September 24, 2007) are accounted for on a trade date basis. The Fund records daily its proportionate share of the Master Portfolio's income, expenses and realized and unrealized gains and losses. In addition, the Fund accrues its own expenses. Certain expenses have been allocated to the individual series of the Bond Fund on a pro rata basis based upon the respective aggregate net asset value of each such series. Prior to September 24, 2007, realized gains and losses on security transactions of the Fund were determined on the identified cost basis. Interest income was recognized on the accrual basis. The Fund amortized all premiums and discounts on debt securities. (e) 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. (f) Prepaid registration fees--Prepaid registration fees are charged to expense as the related shares are issued. (g) Dividends and distributions--Dividends from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend dates. (h) Securities lending--Prior to September 24, 2007, the Fund lent securities to financial institutions that provided cash or securities issued or guaranteed by the U.S. government as collateral, which were 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 was determined at the close of business and any additional required collateral was delivered to the Fund on the next business day. Where the Fund received securities as collateral for the loaned securities, it collected a fee from the borrower. The Fund typically received the income on the loaned securities but did not receive the income on the collateral. Where the Fund received cash collateral, it would 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. (i) TBA commitments--Prior to September 24, 2007, the Fund entered 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 Fund's other assets. Unsettled TBA commitments were valued at the current market value of the underlying securities, according to the procedures described under "Valuation of investments." (j) Reverse repurchase agreements--Prior to September 24, 2007, the Fund entered into reverse repurchase agreements. Under reverse repurchase agreements, the Fund sold securities to the counterparty and agreed to repurchase them at a mutually agreed upon date and price, and may have exchanged their respective commitments to pay or receive interest. If the counterparty defaulted on its obligation, the Fund's ability to receive interest would be delayed or limited. Furthermore, if the Fund did not have sufficient client income to pay its obligation under the reverse repurchase agreement, the Fund would be in default and the counterparty would have been able to terminate the repurchase agreement. At the time the Fund entered into a reverse repurchase agreement, it would have established 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. (k) Mortgage dollar rolls--Prior to September 24, 2007, the Fund sold mortgage- backed 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. (l) 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. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements (continued) BlackRock Total Return Fund In addition, in February 2007, FASB "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. 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. (m) Reclassifications - U.S. generally accepted accounting principles require that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. Accordingly, during the current year, $2,086,934 has been reclassified between paid-in capital in excess of par and accumulated net realized capital losses, $56,897,715 has been reclassified between accumulated net realized capital losses and paid-in capital in excess of par and $6,001,575 has been reclassified between distributions in excess of net investment income and paid-in capital in excess of par as a result of permanent differences attributable to the expiration of capital loss carryforwards and the difference between the surviving entity for tax and accounting purposes. These reclassifications have no effect on net assets or net asset values per share. 2. Investment Advisor Agreement and Transactions with Affiliates: The Bond Fund has entered into an Investment Advisory Agreement with the Manager. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are the principal owners of BlackRock, Inc. The Bond Fund 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 each of the Bond Fund's portfolios, including the Fund, and provides the necessary personnel, facilities, equipment and certain other services necessary to the operation of the Bond Fund. For such services, effective September 24, 2007 the Manager receives, at the end of each month, a fee with respect to the Fund at the annual rates set forth below which are based upon the aggregate average daily value of the Bond Fund's net assets at the following annual rates: .50% of the Bond Fund's average daily net assets not exceeding $250 million; .45% of the average daily net assets in excess of $250 million but not exceeding $500 million; .40% of average daily net assets in excess of $500 million but not exceeding $750 million; and .35% of average daily net assets in excess of $750 million. For the year ended September 30, 2007, the aggregate average daily net assets of the Bond Fund, including the Fund and the Bond Fund's other series, BlackRock High Income Fund, was approximately $3,922,606,000. Effective September 24, 2007, the Manager has contractually agreed to waive the Fund's investment advisory fee in the amount of the Fund's share of the investment advisory fee paid by the Fund. For the period September 24, 2007 to September 30, 2007, the Manager earned fees of $213,632 of which $78,148 were waived. For the period October 1, 2006 to September 24, 2007, the Total Return Portfolio paid the Manager at the following annual rates, based on its average daily net assets: .50% of its average daily net assets not exceeding $1 billion; .45% of its average daily net assets in excess of $1 billion but not exceeding $2 billion; .425% of its average daily net assets in excess of $2 billion but not exceeding $3 billion; and .40% of its average daily net assets in excess of $3 billion. For the year ended September 30, 2007, the Manager contractually agreed to waive and/or reimburse fees and/or expenses in order to limit expenses (excluding interest expense and certain other fund expenses) as a percentage of average daily net assets allocated to each class of the Fund as follows: 1.65% (for Investor B2 Shares), .85% (for Service Shares) and .40% (for BlackRock Shares), until February 1, 2008. In addition to the contractual waivers described above, the Manager has voluntarily agreed to waive and/or reimburse fees or expenses in order to limit expenses (excluding interest expense and certain other Fund expenses) as a percentage of average daily net assets allocated to each class of the Fund as follows: 1.53% (for Investor B2 Shares) and .76% (for Service Shares). The Manager has agreed not to reduce or discontinue this voluntary waiver or reimbursement until September 30, 2008, unless approved by the Board of Directors of the Fund, including a majority of the non-interested Directors. In addition, the Manager has entered into a sub-advisory agreement with BlackRock Financial Management, Inc., an affiliate of the Manager, under which the Manager pays the sub-adviser a fee that is a percentage of the Management fee paid by the Fund to the Manager. There is no increase in the aggregate fees paid by the Bond Fund for these services. For the period October 1, 2006 to September 24, 2007, PFPC Inc. ("PFPC"), an indirect wholly owned subsidiary of PNC and an affiliate of the Manager, and the Manager acted as co-administrators for the Fund. For these services, the co-administrators received a combined administration fee computed daily and payable monthly, based on a percentage of the average daily net assets of the Fund. The combined administration fee was paid at the following annual rates: ..075% of the first $500 million of net assets of the Fund, .065% of the next $500 million and .055% of assets in excess of $1 billion. In addition, each of the share classes is charged an administration fee based on the following percentage of average daily net assets of each respective class: .025% of the first $500 million, .015% of the next $500 million and .005% of assets in excess of $1 billion. In addition, PFPC and the Manager may have, at their discretion, voluntarily waived all or any portion of their administration fees for any share class.

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).

The Fund 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 Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the 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. 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 BlackRock Total Return Fund of BlackRock Bond Fund, Inc. as of September 30, 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 its 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.

See Notes to Financial Statements. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements Master Total Return Portfolio 1. Significant Accounting Policies: Master Total Return Portfolio (formerly "Master Bond Portfolio") (the "Master Portfolio") is a part of Master Bond LLC (the "Master LLC") and 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 (the "LLC Agreement") permits the Directors (and prior to June 15, 2007, the Declaration of Trust permitted the Trustees) to issue nontransferable interests in the Master LLC/Trust, subject to certain limitations. Throughout this report the Trust and the Master LLC are referred to as the Master LLC and the Board of Directors of the Master LLC and the Board of Trustees of the Trust are referred to as the Board of Directors. The Master Portfolio'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. The following is a summary of significant accounting policies followed by the Master Portfolio. (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 of the Master LLC. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their closing prices as of the close of such exchanges. Effective September 4, 2007, exchange traded options are valued at the mean price and previously were valued at the last sale price. Options traded in the OTC market are valued at the last asked price (options written) or the last bid price (options purchased). Swap agreements and options thereon are valued based upon quoted fair valuations received daily by the Master Portfolio from a pricing service or counterparty. Valuation of short-term investment vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Reverse repurchase agreements are valued at cost. 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 of the Master LLC. Equity securities held by the Master Portfolio 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 of the Master LLC. Long positions traded in the 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 in accordance with a valuation policy approved by the Board of Directors of the Master LLC. 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. Generally, trading in foreign securities is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Master Portfolio 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 Master Portfolio's 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 may be valued at their fair value as determined in good faith by the Master LLC's 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 Master LLC's Board of Directors. (b) Derivative financial instruments--The Master Portfolio may engage in various portfolio investment strategies both to increase the return of the Master Portfolio 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 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. * Financial futures contracts--The Master Portfolio 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 Master Portfolio deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Master Portfolio 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 Master Portfolio as unrealized gains or losses. When the contract is closed, the Master Portfolio 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. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements (continued) Master Total Return Portfolio * Options--The Master Portfolio may purchase and write call and put options. When the Master Portfolio writes an option, an amount equal to the premium received by the Master Portfolio 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 Master Portfolio enters into a closing transaction), the Master Portfolio 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. * Forward foreign exchange contracts--The Master Portfolio may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Master Portfolio as an unrealized gain or loss. When the contract is closed, the Master Portfolio records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. * Foreign currency options and futures--The Master Portfolio may also purchase or sell listed or OTC foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions may be effected with respect to hedges on non-U.S. dollar-denominated securities owned by the Master Portfolio, sold by the Master Portfolio but not yet delivered, or committed or anticipated to be purchased by the Master Portfolio. * Swaps--The Master Portfolio may enter into swap agreements, which are OTC contracts in which the Master Portfolio 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 Master Portfolio 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) 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 Master Portfolio 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--The Master Portfolio is classified as a partnership for federal income tax purposes. As such, each investor in the Master Portfolio is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Master Portfolio. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. It is intended that the Master Portfolio's assets will be managed so an investor in the Master Portfolio 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. 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 Master Portfolio has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Securities lending--The Master 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 Master Portfolio and any additional required collateral is delivered to the Master Portfolio on the next business day. Where the Master Portfolio receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Master Portfolio typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Master 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 five business days. The Master Portfolio 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 Master Portfolio could experience delays and costs in gaining access to the collateral. The Master 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. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements (continued) Master Total Return Portfolio (g) TBA commitments--The Master Portfolio 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 Master Portfolio's 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." (h) Reverse repurchase agreements--The Master Portfolio may enter into repurchase agreements. Under reverse repurchase agreements, the Master Portfolio 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 Master Portfolio's ability to receive interest will be delayed or limited. Furthermore, if the Master Portfolio does not have sufficient client income to pay its obligation under the reverse repurchase agreement, the Master Portfolio would be in default and the counterparty would be able to terminate the repurchase agreement. At the time the Master Portfolio 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. (i) Mortgage dollar rolls--The Master Portfolio may sell mortgage-backed 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. (j) 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 Master Portfolio'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 Master Portfolio's financial statements, if any, has not been determined. In addition, in February 2007, FASB 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. At this time, management is evaluating the implications of FAS 159 and its impact on the Master Portfolio's financial statements, if any, has not been determined. 2. Investment Advisory Agreement and Transactions with Affiliates: The Master LLC, on behalf of the Master Portfolio, 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 Master Portfolio's investments and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Master Portfolio. For such services, the Master Portfolio pays a monthly fee with respect to the Master Portfolio based upon the aggregate average daily value of the net assets of the Master Portfolio and BlackRock High Income Fund of BlackRock Bond Fund, Inc. at an annual rate of .20% of the average daily net assets not exceeding $250 million; .15% of average daily net assets in excess of $250 million but less than $500 million; .10% of average daily net assets in excess of $500 million but less than $750 million and .05% in excess of $750 million. For the year ended September 30, 2007, the aggregate average daily net assets of the Master Portfolio and BlackRock High Income Fund was approximately $4,786,830,000. In addition, the Manager has entered into a Sub-Advisory Agreement with BlackRock Financial Management, Inc., an affiliate of the Manager, under which the Manager pays the sub-adviser for services it provides a monthly fee at an annual rate that is a percentage of the management fee paid by the Master Portfolio to the Manager. BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Notes to Financial Statements (concluded) Master Total Return Portfolio The Master Portfolio 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 Portfolio has retained BlackRock Investment Management, LLC ("BIM") 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 Portfolio, invest cash collateral received by the Master LLC for such loans, among other things, in a private investment company managed by the Manager or in registered money market funds advised by the Manager or its affiliates. For the year ended September 30, 2007, BIM received $81,040 in securities lending agent fees from the Master Portfolio. For the year ended September 30, 2007, the Master Portfolio reimbursed the Manager $62,443 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, for the year ended September 30, 2007 were $6,756,331,976 and $7,230,855,196, respectively.

Short-Term Borrowings: The Master Portfolio, 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, which expires November 2007. The Master Portfolio may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Master Portfolio may borrow up to the maximum amount allowable under the Master Portfolio's current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Master Portfolio pays a commitment fee of .06% per annum based on the Master Portfolio's 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.

Reverse Repurchase Agreements: For the period ended September 24, 2007 to September 30, 2007 the Master Portfolio's average amount outstanding was approximately $51,022,000 and daily weighted average interest rate was 4.56%. 6. Acquisitions: On October 16, 2006, an investor of the Master Portfolio acquired all of the net assets of BlackRock Intermediate Term Fund of BlackRock Bond Fund, Inc. pursuant to a plan of reorganization. As a result of the reorganization, which included $674,588 of net unrealized depreciation, the Master Portfolio received an in-kind contribution of portfolio securities. On September 24, 2007, an investor of the Master Portfolio acquired all of the net assets of BlackRock Total Return Portfolio of BlackRock Funds II, pursuant to a plan of reorganization.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2007 Report of Independent Registered Public Accounting Firm Master Total Return Portfolio To the Investors and Board of Directors of Master Bond LLC: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Total Return Portfolio, (formerly Master Bond Portfolio), of Master Bond LLC (formerly Master Bond Trust) (the "Master LLC") as of September 30, 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 the respective periods 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 the 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 September 30, 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 Total Return Portfolio of Master Bond LLC as of September 30, 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 its financial highlights for the respective periods then ended, in conformity with accounting principles generally accepted in the United States of America.

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.
