The Markets in Review

Dear Shareholder,

Diverging monetary policies and shifting economic outlooks across regions were the overarching themes driving financial markets during the 12-month period ended September 30, 2015. U.S. economic growth was picking up considerably in the fourth quarter of 2014, while the broader global economy showed signs of slowing. Investors favored the stability of U.S. assets despite expectations that the Federal Reserve (the “Fed”) would eventually be inclined to raise short-term interest rates. International markets struggled even as the European Central Bank and the Bank of Japan eased monetary policy. Oil prices plummeted in late 2014 due to a global supply-and-demand imbalance, fueling a sell-off in energy-related assets and emerging markets. Investors piled into U.S. Treasury bonds as their persistently low yields had become attractive as compared to the even lower yields on international sovereign debt.

Equity markets reversed in early 2015, with international markets outperforming the United States as global risks temporarily abated and the U.S. economy hit a soft patch amid a harsh winter and a west coast port strike. High valuations took their toll on U.S. stocks, while bond yields fell to extreme lows. (Bond prices rise as yields fall.) In contrast, economic reports in Europe and Asia began to improve, and accommodative policies from central banks in those regions helped international equities rebound. Oil prices stabilized, providing some relief for emerging market stocks, although a stronger U.S. dollar posed another significant headwind for the asset class.

U.S. economic growth regained momentum in the second quarter, helping U.S. stocks resume an upward path; however, the improving data underscored the likelihood that the Fed would raise short-term rates before the end of 2015 and bond yields moved swiftly higher. The month of June brought a sharp, but temporary, sell-off across most asset classes as Greece’s long-brewing debt troubles came to an impasse. These concerns abated when the Greek parliament passed a series of austerity and reform measures in July. But the market’s calm was short-lived. Signs of weakness in China’s economy sparked extreme levels of volatility in Chinese equities despite policymakers’ attempts to stabilize the market.

Higher volatility spread through markets globally in the third quarter as further evidence of deceleration in China stoked worries about overall global growth. Weakening demand caused oil prices to slide once again, igniting another steep sell-off in emerging markets. Global volatility spiked higher as investors speculated whether the Fed would raise rates at its September meeting. News that the rate hike had been postponed brought little relief in the markets as the central bank’s decision reinforced investors’ concerns about the state of the global economy. Global equities and high yield bonds broadly declined, while higher quality assets, including U.S. Treasury bonds, municipal bonds and investment grade credit benefited from investors seeking shelter amid global uncertainty.

At BlackRock, we believe investors need to think globally, extend their scope across a broad array of asset classes and be prepared to move freely as market conditions change over time. We encourage you to talk with your financial advisor and visit blackrock.com for further insight about investing in today’s markets.

Fund Summary as of September 30, 2015

      Investment Objective

BlackRock Total Return Fund’s (the “Fund”) investment objective is to realize a total return that exceeds that of the Barclays U.S. Aggregate Bond Index.

      Portfolio Management Commentary

On June 23, 2015, the Fund’s Investor B1 Shares converted to Investor A1 Shares. In addition, on September 1, 2015, the Fund’s BlackRock Shares were redesignated to Class K Shares.

How did the Fund perform?

• For the 12-month period ended September 30, 2015, the Fund, through its investment in Master Total Return Portfolio (the “Master Portfolio”), underperformed its benchmark, the Barclays U.S. Aggregate Bond Index.

What factors influenced performance?

• The main detractors from performance were the Master Portfolio’s underweight U.S. duration (sensitivity to interest rate movements) positioning along with its exposure to U.S. Treasury Inflation Protected Securities (“TIPS”) in breakeven form. (“Breakeven” refers to the spread between real and nominal yields.)

• The most significant contributors to performance were the Master Portfolio’s overweight allocation to securitized assets such as commercial mortgage-backed securities and asset-backed securities, and the Master Portfolio’s tactical shifts with respect to its weighting in U.S. investment grade credits. The Master Portfolio’s allocations in municipal securities and high yield securities and its active currency positioning also added to relative return.

• The Master Portfolio held derivatives during the period as a part of its investment strategy. Derivatives are used by the Master Portfolio as a means to manage risk and/or take outright views on interest rates, credit risk and/or foreign exchange positions in the Master Portfolio. During

the period, the Master Portfolio’s derivative holdings had a positive impact on performance.

Describe recent portfolio activity.

• During the period, the Master Portfolio tactically adjusted the duration of its U.S. holdings, maintaining a modest underweight there for almost the entire period. The Master Portfolio also kept an underweight in U.S. investment grade credit given low yields in early 2015, but began to reduce the underweight as yields rose in the second quarter. The Master Portfolio also reduced its allocation in municipal bonds and tactically traded its high yield bond exposure. In addition, given the strong performance experienced by securitized assets and increasing macroeconomic concerns, the Master Portfolio’s allocation in securitized assets was slightly reduced near period end. In terms of currency allocation, the Master Portfolio maintained a strong U.S. dollar bias early in the period, but gradually scaled this back beginning in March 2015 on uncertainty surrounding U.S. Federal Reserve policy.

Describe portfolio positioning at period end.

• Relative to the Barclays U.S. Aggregate Bond Index, the Master Portfolio ended the period modestly underweight U.S. duration and U.S. investment grade credit. The Master Portfolio remained overweight securitized assets, despite some trimming late in the period. The Fund also held modest exposures in U.S. high yield securities, municipal securities, non-U.S. securities and TIPS.

The views expressed reflect the opinions of BlackRock as of the date of this report and are subject to change based on changes in market, economic or other conditions. These views are not intended to be a forecast of future events and are no guarantee of future results.

Performance information reflects past performance and does not guarantee future results. Current performance may be lower or higher than the performance data quoted. Refer to www.blackrock.com/funds to obtain performance data current to the most recent month end. Performance results do not reflect the deduction of taxes that a shareholder would pay on Fund distributions or the redemption of Fund shares. Figures shown in the performance tables on the previous page assume reinvestment of all distributions, if any, at NAV on the ex-dividend/ 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. Distributions paid to each class of shares will vary because of the different levels of service, distribution and transfer agency fees applicable to each class, which are deducted from the income available to be paid to shareholders.

BlackRock Advisors, LLC (the “Manager”), the Fund’s investment advisor, waived and/or reimbursed a portion of the Fund’s expenses. Without such waiver and/or reimbursement, the Fund’s performance would have been lower. The Manager is under no obligation to continue waiving or reimbursing its fees after the applicable termination date. See Note 4 of the Notes to Financial Statements for additional information on waivers and reimbursements. The standardized 30-day yield includes the effects of any waivers and/or reimbursements. The unsubsidized 30-day yield excludes the effects of any waivers and/or reimbursements.

Disclosure of Expenses

Shareholders of the Fund may incur the following charges: (a) transactional expenses, such as sales charges; and (b) operating expenses, including investment advisory fees, administration fees, service and distribution fees, including 12b-1 fees, acquired fund fees and expenses and other fund expenses. The expense examples shown below (which is based on a hypothetical investment of $1,000 invested on April 1, 2015 and held through September 30, 2015) 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 expense example provides information about actual account values and actual expenses. In order to estimate the expenses a shareholder paid during the period covered by this report, shareholders can divide their account value by $1,000 and then multiply the result by the number corresponding to their share class under the heading entitled “Expenses Paid During the Period.”

The expense example 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 the Fund and other funds, compare the 5% hypothetical examples with the 5% hypothetical examples that appear in shareholder reports of other funds.

The expenses shown in the expense example are intended to highlight shareholders’ ongoing costs only and do not reflect any transactional expenses, such as sales charges, if any. Therefore, the hypothetical examples are 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.

The Benefits and Risks of Leveraging

The Master Portfolio may utilize leverage to seek to enhance yield and NAV. However, these objectives cannot be achieved in all interest rate environments.

The Master Portfolio may utilize leverage by entering into reverse repurchase agreements and/or treasury roll transactions. In general, the concept of leveraging is based on the premise that the financing cost of leverage, which is based on short-term interest rates, is normally lower than the income earned by the Master Portfolio on its longer-term portfolio investments purchased with the proceeds from leverage. To the extent that the total assets of the Master Portfolio (including the assets obtained from leverage) are invested in higher-yielding portfolio investments, the Master Portfolio’s investors will benefit from the incremental net income.

The interest earned on securities purchased with the proceeds from leverage is distributed to the shareholders, and the value of these portfolio holdings is reflected in the Master Portfolio’s per share NAV. However, in order to benefit shareholders, the return on assets purchased with leverage proceeds must exceed the ongoing costs associated with the leverage. If interest and other ongoing costs of leverage exceed the Master Portfolio’s return on assets purchased with leverage proceeds, income to shareholders will be lower than if the Master Portfolio had not used leverage.

Furthermore, the value of the Master Portfolio’s investments generally varies inversely with the direction of long-term interest rates, although other factors can influence the value of portfolio investments. As a result, changes in interest rates can influence the Master Portfolio’s NAV positively or negatively in addition to the impact on the Master Portfolio’s performance from leverage. Changes in the direction of interest rates are difficult to predict accurately, and there is no assurance that the Master Portfolio’s leveraging strategy will be successful.

The use of leverage also generally causes greater changes in the Master Portfolio’s NAV and dividend rates than it would in a comparable fund that does not use leverage. In a declining market, leverage is likely to cause a greater decline in the NAV of the Master Portfolio’s shares than if the Master Portfolio were not leveraged. In addition, the Master Portfolio may be required to sell portfolio securities at inopportune times or at distressed values in order to comply with regulatory requirements applicable to the use of leverage or as required by the terms of leverage instruments, which may cause the Master Portfolio to incur losses. The use of leverage may limit the Master Portfolio’s ability to invest in certain types of securities or use certain types of hedging strategies. The Master Portfolio incurs expenses in connection with the use of leverage, all of which are borne by Master Portfolio investors and may reduce income.

Derivative Financial Instruments

The Master Portfolio may invest in various derivative financial instruments. Derivative financial instruments are used to obtain exposure to a security, index and/or market without owning or taking physical custody of securities or to manage market, equity, credit, interest rate, foreign currency exchange rate, commodity and/or other risks. Derivative financial instruments may give rise to a form of economic leverage. Derivative financial instruments also involve risks, including the imperfect correlation between the value of a derivative financial instrument and the underlying asset, possible default of the counterparty to the transaction or illiquidity of the derivative financial instrument. The Master Portfolio’s

ability to use a derivative financial instrument successfully depends on the investment advisor’s ability to predict pertinent market movements accurately, which cannot be assured. The use of derivative financial instruments may result in losses greater than if they had not been used, may limit the amount of appreciation the Master Portfolio can realize on an investment and/or may result in lower distributions paid to shareholders. The Master Portfolio’s investments in these instruments are discussed in detail in the Master Portfolio’s Notes to Consolidated Financial Statements.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 21

Notes to Financial Statements BlackRock Total Return Fund

1. Organization:

BlackRock Total Return Fund (the “Fund”) is a series of BlackRock Bond Fund, Inc. (the “Corporation”) and is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, open-end management investment company. The Fund seeks to achieve its investment objective by investing all of its assets in Master Total Return Portfolio (the “Master Portfolio”) of Master Bond LLC (the “Master LLC”), an affiliate of the Fund, which has the same investment objective and strategies as the Fund. The Corporation is organized as a Maryland corporation. The Master LLC is organized as a Delaware limited liability company. 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. At September 30, 2015, the percentage of the Master Portfolio owned by the Fund was 94.1%. The consolidated financial statements of the Master Portfolio, including the Consolidated Schedule of Investments, are included elsewhere in this report and should be read in conjunction with the Fund’s financial statements.

The Fund offers multiple classes of shares. All classes of shares have identical voting, dividend, liquidation and other rights and are subject to the same terms and conditions, except that certain classes bear expenses related to the shareholder servicing and distribution of such shares. Institutional and Class K Shares are sold only to certain eligible investors. Investor A1, B, C1 and C2 Shares are only available through exchanges and distribution reinvestments by current holders and for purchase by certain employer-sponsored retirement plans. Investor A and Investor C Shares are generally available through financial intermediaries. Class R Shares are available only to certain employer-sponsored retirement plans. Each class has exclusive voting rights with respect to matters relating to its shareholder servicing and distribution expenditures (except that Investor B shareholders may vote on material changes to the Investor A distribution and service plan).

Share Class	Initial Sales Charge	CDSC	Conversion Privilege
Institutional, Service, Class K1 and Class R Shares	No	No	None
Investor A and Investor A1 Shares	Yes	No2	None
			To Investor A Shares after
Investor B Shares	No	Yes	approximately 10 years
Investor C, Investor C1 and Investor C2 Shares	No	Yes	None

¹  On September 1, 2015, the Fund’s BlackRock Shares were redesignated as Class K Shares.

²  Investor A Shares may be subject to a CDSC where no initial sales charge was paid at the time of purchase.

On June 23, 2015, the Fund’s Investor B1 Shares converted into Investor A1 Shares, with the same relative aggregate net asset value as the original shares held immediately prior to such conversion.

The Fund, together with certain other registered investment companies advised by the Manager or its affiliates, is included in a complex of open-end funds referred to as the Equity-Bond Complex.

2. Significant Accounting Policies:

The Fund’s financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Fund is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. The following is a summary of significant accounting policies followed by the Fund:

Investment Transactions and Investment Income: For financial reporting purposes, contributions to and withdrawals from the Master Portfolio are accounted 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. Realized and unrealized gains and losses are adjusted utilizing partnership tax allocation rules. In addition, the Fund accrues its own expenses. Income, expenses and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets.

Distributions: Distributions from net investment income are declared daily and paid monthly. Distributions of capital gains are recorded on the ex-dividend date. The character and timing of distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP.

Net income and realized gains from investments held by the Master Portfolio’s investment in BlackRock Cayman Master Total Return Portfolio I, Ltd. (the “Subsidiary”) are treated as ordinary income for tax purposes. If a net loss is realized by the Subsidiary in any taxable year, the loss will generally not be available to offset the Fund’s ordinary income and/or capital gains for that year.

Indemnifications: In the normal course of business, the Fund enters into contracts that contain a variety of representations that provide general indemnification. The Fund’s maximum exposure under these arrangements is unknown because it involves future potential claims against the Fund, which cannot be predicted with any certainty.

22 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Financial Statements (continued) BlackRock Total Return Fund

Other: Expenses directly related to the Fund or its classes are charged to the Fund or the applicable class. Other operating expenses shared by several funds are prorated among those funds on the basis of relative net assets or other appropriate methods. Expenses directly related to the Fund and other shared expenses prorated to the Fund are allocated daily to each class based on its relative net assets or other appropriate methods.

The Fund has an arrangement with its custodian whereby fees may be reduced by credits earned on uninvested cash balances, which, if applicable, are shown as fees paid indirectly in the Statement of Operations. The custodian imposes fees on overdrawn cash balances, which can be offset by accumulated credits earned or may result in additional custody charges.

3. Investment Valuation and Fair Value Measurements:

The Fund’s policy is to value its financial instruments at fair value. The Fund records its investment in the Master Portfolio at fair value based on the Fund’s proportionate interest in the net assets of the Master Portfolio. Valuation of securities held by the Master Portfolio is discussed in Note 3 of the Master Portfolio’s Notes to Financial Statements, which are included elsewhere in this report.

4. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. is the largest stockholder and an affiliate of BlackRock, Inc. (“BlackRock”), for 1940 Act purposes.

The Corporation, on behalf of the Fund, entered into an Investment Advisory Agreement with the Manager, the Fund’s investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of the Fund’s portfolio and provides the necessary personnel, facilities, equipment and certain other services to the operations of the Fund. For such services, the Fund pays the Manager a monthly fee based on a percentage of the combined average daily net assets of the Fund and the Master Portfolio at the following annual rates for the periods indicated:

Average daily net assets	Investment Advisory Fee
	Period October 1, 2014 to November 20, 2014	Period November 21, 2014 to September 30, 20151
First $250 million	0.50%	0.32%
$250 million - $500 million	0.45%	0.31%
$500 million - $750 million	0.40%	0.30%
Greater than $750 million	0.35%	0.29%

¹  This investment advisory fee applies to the Fund for as long as the Fund invests in the Master Portfolio or another master fund advised by the Manager or an affiliate thereof in a master-feeder structure. If the Fund ceases to operate as a feeder fund in a master/feeder structure, the maximum actual investment advisory fees payable to the Manager (as a percentage of average daily net assets) by the Fund are as follows: 0.48% (first $250 million), 0.43% ($250 million - $500 million), 0.38% ($500 million - $750 million) and 0.34% (greater than $750 million).

Prior to November 21, 2014, the Manager contractually agreed to waive its investment advisory fees by the amount of the Fund’s share of the investment advisor’s fee paid to the Master Portfolio. For the year ended September 30, 2015, the Manager waived $420,532, which is included in fees waived by the Manager in the Statement of Operations.

The Manager, on behalf of the Fund, entered into separate sub-advisory agreements with BlackRock International Limited (“BIL”) and BlackRock (Singapore) Limited (“BRS”), each an affiliate of the Manager. The Manager pays BIL and BRS for services they provide, a monthly fee that is a percentage of the investment advisory fees paid by the Master Portfolio to the Manager.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 23

Notes to Financial Statements (continued) BlackRock Total Return Fund

The Corporation, on behalf of the Fund, entered into a Distribution Agreement and a Distribution and Service Plan with BlackRock Investments, LLC (“BRIL”), an affiliate of the Manager. Pursuant to the Distribution and Service Plan and in accordance with Rule 12b-1 under the 1940 Act, the Fund pays BRIL ongoing service and distribution fees. The fees are accrued daily and paid monthly at annual rates based upon the average daily net assets of the relevant share class of the Fund as follows:

The ongoing service and/or distribution fee compensates BRIL and each broker-dealer for providing shareholder servicing and/or distribution related services to Service, Investor A, Investor A1, Investor B, Investor C, Investor C1, Investor C2 and Class R shareholders.

Pursuant to written agreements, certain financial intermediaries, some of which may be affiliates, provide the Fund with sub-accounting, recordkeeping, sub-transfer agency and other administrative services with respect to sub-accounts they service. For these services, these entities receive an asset-based fee or annual fee per shareholder account, which will vary depending on share class and/or net assets. For the year ended September 30, 2015, the Fund paid the following amounts to affiliates of BlackRock in return for these services, which are included in transfer agent — class specific in the Statement of Operations:

Institutional	$	560,900
Investor A	$	149

The Manager maintains a call center, which is responsible for providing certain shareholder services to the Fund, such as responding to shareholder inquiries and processing transactions based upon instructions from shareholders with respect to the subscription and redemption of Fund shares.

5. Income Tax Information:

It is the Fund’s policy to comply with the requirements of the Internal Revenue Code of 1986, as amended, 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.

The Fund files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Fund’s U.S. federal tax returns remains open for each of the four years ended September 30, 2015. The statutes of limitations on the Fund’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Fund as of September 30, 2015, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Fund’s financial statements.

U.S. GAAP requires that certain components of net assets be adjusted to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net assets or net asset values per share. As of period end, the following permanent differences attributable to foreign currency transactions and the timing and recognition of partnership income were reclassified to the following accounts:

Paid-in capital	$	1,657,697
Undistributed net investment income	$	73,389,743
Accumulated net realized loss	$	(75,047,440	)

The tax character of distributions paid was as follows:

	9/30/15	9/30/14
Ordinary income	$172,310,777	$101,331,300

26 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Financial Statements (continued) BlackRock Total Return Fund

As of period end, the tax components of accumulated net losses were as follows:

Undistributed ordinary income	$	33,614,787
Capital loss carryforward		(8,923,840	)
Net unrealized losses1		(94,187,567	)
Total	$	(69,496,620	)

¹  The difference between book-basis and tax-basis net unrealized losses was attributable primarily to the timing and recognition of partnership income.

As of period end, the Fund had a capital loss carryforward available to offset future realized capital gains of $8,923,840, all of which is due to expire September 30, 2018.

During the year ended September 30, 2015, the Fund utilized $10,083,759 of its capital loss carryforward.

6. Bank Borrowings:

The Master LLC, on behalf of the Master Portfolio, along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), is a party to a 364-day, $2.1 billion credit agreement with a group of lenders, under which the Master Portfolio may borrow to fund shareholder redemptions. Excluding commitments designated for certain individual funds, the Participating Funds, including the Master Portfolio, can borrow up to an aggregate commitment amount of $1.6 billion, subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.06% per annum on unused commitment amounts and interest at a rate equal to the higher of (a) one-month LIBOR (but, in any event, not less than 0.00%) on the date the loan is made plus 0.80% per annum or (b) the Fed Funds rate (but, in any event, not less than 0.00%) in effect from time to time plus 0.80% per annum on amounts borrowed. The agreement expires in April 2016 unless extended or renewed. Prior to November 25, 2014, the aggregate commitment amount was $1.1 billion, of which the Participating Funds, including the Master Portfolio, could borrow up to $650 million at any time outstanding, subject to asset coverage and other limitations as specified in the agreement. Participating Funds paid administration, legal and arrangement fees, which, if applicable, are included in miscellaneous expenses in the Statement of Operations, and along with commitment fees, were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the year ended September 30, 2015, the Master Portfolio did not borrow under the credit agreement.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 29

Report of Independent Registered Public Accounting Firm

To the Board of Directors of BlackRock Bond Fund, Inc.

and Shareholders of BlackRock Total Return Fund:

We have audited the accompanying statement of assets and liabilities of BlackRock Total Return Fund (the “Fund”), a series of BlackRock Bond Fund, Inc., as of September 30, 2015, 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 period then ended. These financial statements and financial highlights are the responsibility of the Fund’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 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, such financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of BlackRock Total Return Fund as of September 30, 2015, 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.

Notes to Consolidated Financial Statements Master Total Return Portfolio

1. Organization:

Master Total Return Portfolio (the “Master Portfolio”), a series of Master Bond LLC (the “Master LLC”), is registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as a diversified, open-end management investment company. The Master LLC is organized as a Delaware limited liability company. The Limited Liability Company Agreement of the Master LLC permits the Board of Directors of the Master LLC (the “Board”) to issue nontransferable interests in the Master LLC, subject to certain limitations.

Basis of Consolidation: The accompanying consolidated financial statements include the accounts of BlackRock Cayman Master Total Return Portfolio I, Ltd. (the “Subsidiary”), which is a wholly owned subsidiary of the Master Portfolio and primarily invests in commodity-related instruments. The Subsidiary enables the Master Portfolio to hold these commodity-related instruments while allowing its investors to satisfy regulated investment company tax requirements. The Master Portfolio may invest up to 25% of its total assets in the Subsidiary. Intercompany accounts and transactions, if any, have been eliminated. The Subsidiary is subject to the same investment policies and restrictions that apply to the Master Portfolio, except that the Subsidiary may invest without limitation in commodity-related instruments.

2. Significant Accounting Policies:

The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”), which may require management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the consolidated financial statements, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates. The Master Portfolio is considered an investment company under U.S. GAAP and follows the accounting and reporting guidance applicable to investment companies. Below is a summary of significant accounting policies:

Foreign Currency: The Master Portfolio’s books and records are maintained in U.S. dollars. Purchases and sales of investments are recorded at the rates of exchange prevailing on the respective dates of such transactions. Generally, when the U.S. dollar rises in value against a foreign currency, the investments denominated in that currency will lose value; the opposite effect occurs if the U.S. dollar falls in relative value.

The Master Portfolio does not isolate changes in the exchange rates from the changes in the market prices of investments held or sold for financial reporting purposes. Accordingly, the effects of changes in exchange rates on investments are not segregated in the Consolidated Statement of Operations from the effects of changes in market prices of those investments, but are included as a component of net realized and unrealized gain (loss) from investments. The Master Portfolio reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for federal income tax purposes.

The Master Portfolio does not isolate the portion of the results of operations arising as a result of changes in the foreign exchange rates from the changes in the market prices of investments held or sold for financial reporting purposes. Accordingly, the effects of changes in foreign currency exchange rates on investments are not segregated in the Consolidated Statement of Operations from the effects of changes in market prices of those investments, but are included as a component of net realized and unrealized gain (loss) from investments. The Master Portfolio reports realized currency gains (losses) on foreign currency related transactions as components of net realized gain (loss) for financial reporting purposes, whereas such components are generally treated as ordinary income for federal income tax purposes. The Master Portfolio has elected to treat realized gains (losses) from certain foreign currency exchange contracts as capital gain (loss) for federal income tax purposes.

Segregation and Collateralization: In cases where the Master Portfolio enters into certain investments (e.g., dollar rolls, TBA sale commitments, financial futures contracts, forward foreign currency exchange contracts, options written, swaps, short sales and structured options), or certain borrowings (e.g., reverse repurchase transactions and treasury roll transactions) that would be treated as “senior securities” for 1940 Act purposes, the Master Portfolio may segregate or designate on its books and records cash or liquid assets having a market value at least equal to the amount of its future obligations under such investments or borrowings. Doing so allows the investment or borrowing to be excluded from treatment as a “senior security.” Furthermore, if required by an exchange or counterparty agreement, the Master Portfolio may be required to deliver/deposit cash and/or securities to/with an exchange, or broker-dealer or custodian as collateral for certain investments or obligations.

Investment Transactions and Investment Income: For financial reporting purposes, investment transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on investment transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend date. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Master Portfolio is informed of the ex-dividend date. Under the applicable foreign tax laws, a withholding tax at various rates may be imposed on capital gains, dividends and interest. Upon notification from issuers, some of the dividend income received from a real estate investment trust may be redesignated as a reduction of cost of the related investment and/or realized gain. Interest income, including amortization and accretion of premiums and discounts on debt securities, is recognized on the accrual basis. Income, expenses and realized and unrealized gains and losses are allocated daily to each class based on its relative net assets.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 87

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

Recent Accounting Standard: In June 2014, the Financial Accounting Standards Board issued guidance to improve the financial reporting of reverse repurchase agreements and other similar transactions. The guidance will require expanded disclosure for entities that enter into reverse repurchase agreements and similar transactions accounted for as secured borrowings. It is effective for financial statements with fiscal years beginning on or after December 15, 2014 and for interim periods beginning after March 31, 2015. Management is evaluating the impact, if any, of this guidance on the Master Portfolio’s financial statement disclosures.

Other: Expenses directly related to the Master Portfolio are charged to the Master Portfolio. Other operating expenses shared by several funds are prorated among those funds on the basis of relative net assets or other appropriate methods.

Indemnifications: In the normal course of business, the Master Portfolio enters into contracts that contain a variety of representations that provide general indemnification. The Master Portfolio’s maximum exposure under these arrangements is unknown because it involves future potential claims against the Master Portfolio, which cannot be predicted with any certainty.

The Master Portfolio has an arrangement with its custodian whereby fees may be reduced by credits earned on uninvested cash balances, which, if applicable, are shown as fees paid indirectly in the Consolidated Statement of Operations. The custodian imposes fees on overdrawn cash balances, which can be offset by accumulated credits earned or may result in additional custody charges.

3. Investment Valuation and Fair Value Measurements:

Investment Valuation Policies: The Master Portfolio’s investments are valued at fair value as of the close of trading on the New York Stock Exchange (“NYSE”) (generally 4:00 p.m., Eastern time). U.S. GAAP defines fair value as the price the Master Portfolio would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. The Master Portfolio determines the fair values of its financial instruments at market value using independent dealers or pricing services under policies approved by the Board. The BlackRock Global Valuation Methodologies Committee (the “Global Valuation Committee”) is the committee formed by management to develop global pricing policies and procedures and to provide oversight of the pricing function for the Master Portfolio for all financial instruments.

Fair Value Inputs and Methodologies: The following methods (or “techniques”) and inputs are used to establish the fair value of the Master Portfolio’s assets and liabilities:

• Equity investments traded on a recognized securities exchange are valued at the official close price each day, if available. For equity investments traded on more than one exchange, the official close price on the exchange where the stock is primarily traded is used. Equity investments traded on a recognized exchange for which there were no sales on that day may be valued at the last available bid (long positions) or ask (short positions) price.

• Bond investments are valued on the basis of last available bid prices or current market quotations provided by dealers or pricing services. Floating rate loan interests are valued at the mean of the bid prices from one or more brokers or dealers as obtained from a pricing service. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments, various relationships observed in the market between investments and calculated yield measures. Asset-backed and mortgage-backed securities are valued by independent pricing services using models that consider estimated cash flows of each tranche of the security, establish a benchmark yield and develop an estimated tranche-specific spread to the benchmark yield based on the unique attributes of the tranche.

• Generally, trading in foreign instruments is substantially completed each day at various times prior to the close of business on the NYSE. Occasionally, events affecting the values of such instruments may occur between the foreign market close and the close of business on the NYSE that may not be reflected in the computation of the Master Portfolio’s net assets. Each business day, the Master Portfolio uses a pricing service to assist with the valuation of certain foreign exchange-traded equity securities and foreign exchange-traded and over-the-counter (“OTC”) options (the “Systematic Fair Value Price”). Using current market factors, the Systematic Fair Value Price is designed to value such foreign securities and foreign options at fair value as of the close of business on the NYSE, which follows the close of the local markets.

• Municipal investments (including commitments to purchase such investments on a “when-issued” basis) are valued on the basis of prices provided by dealers or pricing services. In determining the value of a particular investment, pricing services may use certain information with respect to transactions in such investments, quotations from dealers, pricing matrixes, market transactions in comparable investments and information with respect to various relationships between investments.

• Investments in open-end registered investment companies are valued at NAV each business day.

• Financial futures contracts traded on exchanges are valued at their last sale price.

88 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

• Securities and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using exchange rates determined as of the close of business on the NYSE. Forward foreign currency exchange contracts are valued at the mean between the bid and ask prices and are determined as of the close of business on the NYSE. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available.

• Exchange-traded options are valued at the mean between the last bid and ask prices at the close of the options market in which the options trade. An exchange-traded option for which there is no mean price is valued at the last bid (long positions) or ask (short positions) price. If no bid or ask price is available, the prior day’s price will be used, unless it is determined that the prior day’s price no longer reflects the fair value of the option. OTC options and options on swaps (“swaptions”) are valued by an independent pricing service using a mathematical model, which incorporates a number of market data factors, such as the trades and prices of the underlying instruments.

• Swap agreements are valued utilizing quotes received daily by the Master Portfolio’s pricing service or through brokers, which are derived using daily swap curves and models that incorporate a number of market data factors, such as discounted cash flows, trades and values of the underlying reference instruments.

• Certain centrally cleared swaps are valued at the price determined by the relevant exchange or clearinghouse.

If events (e.g., a company announcement, market volatility or a natural disaster) occur that are expected to materially affect the value of such instruments, or in the event that the application of these methods of valuation results in a price for an investment that is deemed not to be representative of the market value of such investment, or if a price is not available, the investment will be valued by the Global Valuation Committee, or its delegate, in accordance with a policy approved by the Board as reflecting fair value (“Fair Valued Investments”). When determining the price for Fair Valued Investments, the Global Valuation Committee, or its delegate, seeks to determine the price that each Fund might reasonably expect to receive or pay from the current sale or purchase of that asset or liability in an arm’s-length transaction. Fair value determinations shall be based upon all available factors that the Global Valuation Committee, or its delegate, deems relevant consistent with the principles of fair value measurement, which include the market approach, income approach and/or in the case of recent investments, the cost approach, as appropriate. The market approach generally consists of using comparable market transactions. The income approach generally is used to discount future cash flows to present value and is adjusted for liquidity as appropriate. These factors include but are not limited to: (i) attributes specific to the investment or asset; (ii) the principal market for the investment or asset; (iii) the customary participants in the principal market for the investment or asset; (iv) data assumptions by market participants for the investment or asset, if reasonably available; (v) quoted prices for similar investments or assets in active markets; and (vi) other factors, such as future cash flows, interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, recovery rates, liquidation amounts and/or default rates. Due to the inherent uncertainty of valuations of such investments, the fair values may differ from the values that would have been used had an active market existed. The Global Valuation Committee, or its delegate, employs various methods for calibrating valuation approaches for investments where an active market does not exist, including regular due diligence of the Master Portfolio’s pricing vendors, regular reviews of key inputs and assumptions, transactional back-testing or disposition analysis to compare unrealized gains and losses to realized gains and losses, reviews of missing or stale prices and large movements in market values and reviews of any market related activity. The pricing of all Fair Valued Investments is subsequently reported to the Board or a committee thereof on a quarterly basis.

Fair Value Hierarchy: Various inputs are used in determining the fair value of investments and derivative financial instruments. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial statement purposes as follows:

• Level 1 — unadjusted price quotations in active markets/exchanges for identical assets or liabilities that the Master Portfolio has the ability to access

• Level 2 — other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market–corroborated inputs)

• Level 3 — unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Master Portfolio’s own assumptions used in determining the fair value of investments and derivative financial instruments)

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The significant unobservable inputs used by the Global Valuation Committee in determining the price for Fair Valued Investments are typically categorized as Level 3. The fair value hierarchy for the Master Portfolio’s investments and derivative financial instruments have been included in the Consolidated Schedule of Investments.

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 89

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

Changes in valuation techniques may result in transfers into or out of an assigned level within the hierarchy. In accordance with the Master Portfolio’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments and derivative financial instruments is based on the pricing transparency of the investments and derivative financial instruments and is not necessarily an indication of the risks associated with investing in those securities.

4. Securities and Other Investments:

Asset-Backed and Mortgage-Backed Securities: The Master Portfolio may invest in asset-backed securities. Asset-backed securities are generally issued as pass-through certificates, which represent undivided fractional ownership interests in an underlying pool of assets, or as debt instruments, which are also known as collateralized obligations, and are generally issued as the debt of a special purpose entity organized solely for the purpose of owning such assets and issuing such debt. Asset-backed securities are often backed by a pool of assets representing the obligations of a number of different parties. The yield characteristics of certain asset-backed securities may differ from traditional debt securities. One such major difference is that all or a principal part of the obligations may be prepaid at any time because the underlying assets (i.e., loans) may be prepaid at any time. As a result, a decrease in interest rates in the market may result in increases in the level of prepayments as borrowers, particularly mortgagors, refinance and repay their loans. An increased prepayment rate with respect to an asset-backed security subject to such a prepayment feature will have the effect of shortening the maturity of the security. In addition, the Master Portfolio may subsequently have to reinvest the proceeds at lower interest rates. If the Master Portfolio has purchased such an asset-backed security at a premium, a faster than anticipated prepayment rate could result in a loss of principal to the extent of the premium paid.

The Master Portfolio may purchase certain mortgage pass-through securities. There are a number of important differences among the agencies and instrumentalities of the U.S. Government that issue mortgage-related securities and among the securities that they issue. For example, mortgage-related securities guaranteed by Ginnie Mae are guaranteed as to the timely payment of principal and interest by Ginnie Mae and such guarantee is backed by the full faith and credit of the United States. However, mortgage-related securities issued by Freddie Mac and Fannie Mae, including Freddie Mac and Fannie Mae guaranteed mortgage pass-through certificates, which are solely the obligations of Freddie Mac and Fannie Mae, are not backed by or entitled to the full faith and credit of the United States, but are supported by the right of the issuer to borrow from the U.S. Treasury.

Non-agency mortgage-backed securities are securities issued by non-governmental issuers and have no direct or indirect government guarantees of payment and are subject to various risks. Non-agency mortgage loans are obligations of the borrowers thereunder only and are not typically insured or guaranteed by any other person or entity. The ability of a borrower to repay a loan is dependent upon the income or assets of the borrower. A number of factors, including a general economic downturn, acts of God, terrorism, social unrest and civil disturbances, may impair a borrower’s ability to repay its loans.

Collateralized Debt Obligations: The Master Portfolio may invest in collateralized debt obligations (“CDOs”), which include collateralized bond obligations (“CBOs”) and collateralized loan obligations (“CLOs”). CBOs and CLOs are types of asset-backed securities. A CDO is an entity that is backed by a diversified pool of debt securities (CBOs) or syndicated bank loans (CLOs). The cash flows of the CDO can be split into multiple segments, called “tranches,” which will vary in risk profile and yield. The riskiest segment is the subordinated or “equity” tranche. This tranche bears the greatest risk of defaults from the underlying assets in the CDO and serves to protect the other, more senior, tranches from default in all but the most severe circumstances. Since it is shielded from defaults by the more junior tranches, a “senior” tranche will typically have higher credit ratings and lower yields than their underlying securities, and often receive investment grade ratings from one or more of the nationally recognized rating agencies. Despite the protection from the more junior tranches, senior tranches can experience substantial losses due to actual defaults, increased sensitivity to future defaults and the disappearance of one or more protecting tranches as a result of changes in the credit profile of the underlying pool of assets.

Inflation-Indexed Bonds: The Master Portfolio may invest in inflation-indexed bonds. Inflation-indexed bonds are fixed income securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation rises or falls, the principal value of inflation-indexed bonds will be adjusted upward or downward, and consequently the interest payable on these securities (calculated with respect to a larger or smaller principal amount) will be increased or reduced, respectively. Any upward or downward adjustment in the principal amount of an inflation-indexed bond will be included as interest income in the Consolidated Statements of Operations, even though investors do not receive their principal until maturity. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

Multiple Class Pass-Through Securities: The Master Portfolio may invest in multiple class pass-through securities, including collateralized mortgage obligations (“CMOs”) and commercial mortgage-backed securities. These multiple class securities may be issued by Ginnie Mae, U.S. Government agencies or instrumentalities or by trusts formed by private originators of, or investors in, mortgage loans. In general, CMOs are debt obligations of a legal entity that are collateralized by, and multiple class pass-through securities represent direct ownership interests in, a pool of residential or commercial mortgage loans or mortgage pass-through securities (the “Mortgage Assets”), the payments on which are used to make payments on the CMOs or multiple pass-through securities. Classes of CMOs include interest only (“IOs”), principal only (“POs”), planned amortization classes and targeted amortization classes. IOs and POs are stripped mortgage-backed securities representing interests in a pool of mortgages, the cash flow from which has

90 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

been separated into interest and principal components. IOs receive the interest portion of the cash flow while POs receive the principal portion. IOs and POs can be extremely volatile in response to changes in interest rates. As interest rates rise and fall, the value of IOs tends to move in the same direction as interest rates. POs perform best when prepayments on the underlying mortgages rise since this increases the rate at which the principal is returned and the yield to maturity on the PO. When payments on mortgages underlying a PO are slower than anticipated, the life of the PO is lengthened and the yield to maturity is reduced. If the underlying Mortgage Assets experience greater than anticipated prepayments of principal, the Master Portfolio may not fully recoup its initial investment in IOs.

Stripped Mortgage-Backed Securities: The Master Portfolio may invest in stripped mortgage-backed securities issued by the U.S. Government, its agencies and instrumentalities. Stripped mortgage-backed securities are usually structured with two classes that receive different proportions of the interest (IOs) and principal (POs) distributions on a pool of Mortgage Assets. The Master Portfolio also may invest in stripped mortgage-backed securities that are privately issued.

Zero-Coupon Bonds: The Master Portfolio may invest in zero-coupon bonds, which are normally issued at a significant discount from face value and do not provide for periodic interest payments. Zero-coupon bonds may experience greater volatility in market value than other debt obligations of similar maturity which provide for regular interest payments.

Capital Trusts and Trust Preferred Securities: The Master Portfolio may invest in capital trusts and/or trust preferred securities. These securities are typically issued by corporations, generally in the form of interest-bearing notes with preferred securities characteristics, or by an affiliated business trust of a corporation, generally in the form of beneficial interests in subordinated debentures or similarly structured securities. The securities can be structured as either fixed or adjustable coupon securities that can have either a perpetual or stated maturity date. For trust preferred securities, the issuing bank or corporation will pay interest to the trust, which will then be distributed to holders of the trust preferred securities as a dividend. Dividends can be deferred without creating an event of default or acceleration, although maturity cannot take place unless all cumulative payment obligations have been met. The deferral of payments does not affect the purchase or sale of these securities in the open market. Payments on these securities are treated as interest rather than dividends for federal income tax purposes. These securities generally are rated below that of the issuing company’s senior debt securities and are freely callable at the issuer’s option.

Preferred Stock: The Master Portfolio may invest in preferred stock. Preferred stock has a preference over common stock in liquidation (and generally in receiving dividends as well) but is subordinated to the liabilities of the issuer in all respects. As a general rule, the market value of preferred stock with a fixed dividend rate and no conversion element varies inversely with interest rates and perceived credit risk, while the market price of convertible preferred stock generally also reflects some element of conversion value. Because preferred stock is junior to debt securities and other obligations of the issuer, deterioration in the credit quality of the issuer will cause greater changes in the value of a preferred stock than in a more senior debt security with similar stated yield characteristics. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Floating Rate Loan Interests: The Master Portfolio may invest in floating rate loan interests. The floating rate loan interests held by the Master Portfolio are typically issued to companies (the “borrower”) by banks, other financial institutions, and privately and publicly offered corporations (the “lender”). Floating rate loan interests are generally non-investment grade, often involve borrowers whose financial condition is troubled or uncertain and companies that are highly leveraged. The Master Portfolio may invest in obligations of borrowers who are in bankruptcy proceedings. Floating rate loan interests may include fully funded term loans or revolving lines of credit. Floating rate loan interests are typically senior in the corporate capital structure of the borrower. Floating rate loan interests generally pay interest at rates that are periodically determined by reference to a base lending rate plus a premium. The base lending rates are generally the lending rate offered by one or more European banks, such as the London Interbank Offered Rate (“LIBOR”), the prime rate offered by one or more U.S. banks or the certificate of deposit rate. Floating rate loan interests may involve foreign borrowers, and investments may be denominated in foreign currencies. The Master Portfolio considers these investments to be investments in debt securities for purposes of its investment policies.

When the Master Portfolio purchases a floating rate loan interest, it may receive a facility fee and when it sells a floating rate loan interest, it may pay a facility fee. On an ongoing basis, the Master Portfolio may receive a commitment fee based on the undrawn portion of the underlying line of credit amount of a floating rate loan interest. Facility and commitment fees are typically amortized to income over the term of the loan or term of the commitment, respectively. Consent and amendment fees are recorded to income as earned. Prepayment penalty fees, which may be received by the Master Portfolio upon the prepayment of a floating rate loan interest by a borrower, are recorded as realized gains. The Master Portfolio may invest in multiple series or tranches of a loan. A different series or tranche may have varying terms and carry different associated risks.

Floating rate loan interests are usually freely callable at the borrower’s option. The Master Portfolio may invest in such loans in the form of participations in loans (“Participations”) or assignments (“Assignments”) of all or a portion of loans from third parties. Participations typically will result in the Master Portfolio having a contractual relationship only with the lender, not with the borrower. The Master Portfolio will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Participations, the Master Portfolio generally will have no right to enforce compliance by the

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 91

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

borrower with the terms of the loan agreement, nor any rights of offset against the borrower, and the Master Portfolio may not benefit directly from any collateral supporting the loan in which it has purchased the Participation. As a result, the Master Portfolio will assume the credit risk of both the borrower and the lender that is selling the Participation. The Master Portfolio’s investment in loan participation interests involves the risk of insolvency of the financial intermediaries who are parties to the transactions. In the event of the insolvency of the lender selling the Participation, the Master Portfolio may be treated as a general creditor of the lender and may not benefit from any offset between the lender and the borrower. Assignments typically result in the Master Portfolio having a direct contractual relationship with the borrower, and the Master Portfolio may enforce compliance by the borrower with the terms of the loan agreement.

In connection with floating rate loan interests, the Master Portfolio may also enter into unfunded floating rate loan interests (“commitments”). In connection with either of these commitments, the Master Portfolio earns a commitment fee, typically set as a percentage of the commitment amount. Such fee income, which is included in interest income in the Consolidated Statements of Operations, is recognized ratably over the commitment period. Commitment fees received in advance and unrecognized are recorded in the Consolidated Statements of Assets and Liabilities as deferred income. Unfunded floating rate loan interests are marked-to-market daily, and any unrealized appreciation (depreciation) is included in the Consolidated Statements of Assets and Liabilities and Consolidated Statements of Operations. As of period end, the Master Portfolio had the following unfunded floating rate loan interests:

Borrower	Par		Commitment Amount		Value		Unrealized Depreciation
Telenet International Finance SA, Term Loan AA,		$2,050,000		$2,040,210		$2,005,167		$(35,043)
CD&R Firefly Bidco Ltd., Facility B,		$   129,898		$   198,977		$   194,701		$  (4,276)

Forward Commitments and When-Issued Delayed Delivery Securities: The Master Portfolio may purchase securities on a when-issued basis and may purchase or sell securities on a forward commitment basis. Settlement of such transactions normally occurs within a month or more after the purchase or sale commitment is made. The Master Portfolio may purchase securities under such conditions with the intention of actually acquiring them, but may enter into a separate agreement to sell the securities before the settlement date. Since the value of securities purchased may fluctuate prior to settlement, the Master Portfolio may be required to pay more at settlement than the security is worth. In addition, the Master Portfolio is not entitled to any of the interest earned prior to settlement. When purchasing a security on a delayed delivery basis, the Master Portfolio assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations. In the event of default by the counterparty, the Master Portfolio’s maximum amount of loss is the unrealized appreciation of unsettled when-issued transactions.

TBA Commitments: The Master Portfolio may enter into TBA commitments. TBA commitments are forward agreements for the purchase or sale of mortgage-backed securities for a fixed price, with payment and delivery on an agreed upon future settlement date. The specific securities to be delivered are not identified at the trade date. However, delivered securities must meet specified terms, including issuer, rate and mortgage terms. When entering into TBA commitments, the Master Portfolio may take possession of or deliver the underlying mortgage-backed securities but can extend the settlement or roll the transaction. TBA commitments involve a risk of loss if the value of the security to be purchased or sold declines or increases, respectively, prior to settlement date.

In order to better define contractual rights and to secure rights that will help the Master Portfolio mitigate its counterparty risk, TBA commitments may be entered into by the Master Portfolio under Master Securities Forward Transaction Agreements (each, an “MSFTA”). An MSFTA typically contains, among other things, collateral posting terms and netting provisions in the event of default and/or termination. The collateral requirements are typically calculated by netting the mark to market amount for each transaction under such agreement and comparing that amount to the value of the collateral currently pledged by the Master Portfolio and the counterparty. Cash collateral that has been pledged to cover the obligations of the Master Portfolio and cash collateral received from the counterparty, if any, is reported separately on the Consolidated Statement of Assets and Liabilities as cash pledged as collateral for TBA commitments or cash received as collateral for TBA commitments, respectively. Non-cash collateral pledged by the Master Portfolio, if any, is noted in the Consolidated Schedule of Investments. Typically, the Master Portfolio is permitted to sell, repledge or use the collateral it receives; however, the counterparty is not permitted to do so. To the extent amounts due to the Master Portfolio are not fully collateralized, contractually or otherwise, the Master Portfolio bears the risk of loss from counterparty non-performance.

Mortgage Dollar Roll Transactions: The Master Portfolio may sell TBA mortgage-backed securities and simultaneously contract to repurchase substantially similar (i.e., same type, coupon and maturity) securities on a specific future date at an agreed upon price. During the period between the sale and repurchase, the Master Portfolio will not be entitled to receive interest and principal payments on the securities sold. The Master Portfolio accounts for mortgage dollar roll transactions as purchases and sales and realizes gains and losses on these transactions. These transactions may increase the Master Portfolio’s portfolio turnover rate. Mortgage dollar rolls involve the risk that the market value of the securities that the Master Portfolio is required to purchase may decline below the agreed upon repurchase price of those securities.

Borrowed Bond Agreements: The Master Portfolio may enter into borrowed bond agreements. In a borrowed bond agreement, the Master Portfolio borrows a bond from a counterparty in exchange for cash collateral. The borrowed bond agreement contains a commitment that the security and the cash will be returned to the counterparty and the Master Portfolio at a mutually agreed upon date. Certain agreements have no stated maturity and can

92 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

be terminated by either party at any time. Borrowed bond agreements are entered into primarily in connection with short sales of bonds. Earnings on cash collateral and compensation to the lender of the bond are based on agreed upon rates between the Master Portfolio and the counterparty. The value of the underlying cash collateral approximates the market value and accrued interest of the borrowed bond. To the extent that a borrowed bond transaction exceeds one business day, the value of the cash collateral in the possession of the counterparty is monitored on a daily basis to ensure the adequacy of the collateral. As the market value of the borrowed bond changes, the cash collateral is periodically increased or decreased with a frequency and in amounts prescribed in the borrowed bond agreement. The Master Portfolio may also experience delays in gaining access to the collateral.

Reverse Repurchase Agreements: The Master Portfolio may enter into reverse repurchase agreements with qualified third party broker-dealers. In a reverse repurchase agreement, the Master Portfolio sells securities to a bank or broker-dealer and agrees to repurchase the same securities at a mutually agreed upon date and price. The Master Portfolio receives cash from the sale to use for other investment purposes. During the term of the reverse repurchase agreement, the Master Portfolio continues to receive the principal and interest payments on the securities sold. Certain agreements have no stated maturity and can be terminated by either party at any time. Interest on the value of the reverse repurchase agreements issued and outstanding is based upon competitive market rates determined at the time of issuance. The Master Portfolio may utilize reverse repurchase agreements when it is anticipated that the interest income to be earned from the investment of the proceeds of the transaction is greater than the interest expense of the transaction. Reverse repurchase agreements involve leverage risk. If the Master Portfolio suffers a loss on its investment of the transaction proceeds from a reverse repurchase agreement, the Master Portfolio would still be required to pay the full repurchase price. Further, the Master Portfolio remains subject to the risk that the market value of the securities repurchased declines below the repurchase price. In such cases, the Master Portfolio would be required to return a portion of the cash received from the transaction or provide additional securities to the counterparty.

For financial reporting purposes, cash received in exchange for securities delivered plus accrued interest due to the counterparty is recorded as a liability in the Consolidated Statements of Assets and Liabilities at face value including accrued interest. Due to the short term nature of the reverse repurchase agreements, face value approximates fair value. Interest payments made by the Master Portfolio to the counterparties are recorded as a component of interest expense in the Consolidated Statements of Operations. In periods of increased demand for the security, the Master Portfolio may receive a fee for use of the security by the counterparty, which may result in interest income to the Master Portfolio.

Treasury Roll Transactions: The Master Portfolio may enter into treasury roll transactions. In a treasury roll transaction, the Master Portfolio sells a Treasury security to a counterparty with a simultaneous agreement to repurchase the same security at an agreed upon price and future settlement date. The Master Portfolio receives cash from the sale of the Treasury security to use for other investment purposes. The difference between the sale price and repurchase price represents net interest income or net interest expense reflective of an agreed upon rate between the Master Portfolio and the counterparty over the term of the borrowing. For U.S. GAAP purposes, a treasury roll transaction is accounted for as a secured borrowing and not as a purchase or sale. During the term of the borrowing, interest income from the Treasury security and the related interest expense on the secured borrowing is recorded by the Master Portfolio on an accrual basis. The Master Portfolio will benefit from the transaction if the income earned on the investment purchased with the cash received in the treasury roll transaction exceeds the interest expense incurred by the Master Portfolio. If the interest expense exceeds the income earned, the Master Portfolio’s net investment income and dividends to shareholders may be adversely impacted. Treasury roll transactions involve leverage risk. If the Master Portfolio suffers a loss on its investment of the transaction proceeds from a Treasury roll transaction, the Master Portfolio would be required to pay the full repurchase price. Further, the Master Portfolio remains subject to the risk that the market value of the Treasury securities that the Master Portfolio is required to repurchase may decline below the agreed upon repurchase price of those securities. In such cases, the Master Portfolio would need to return a portion of the cash received from the transaction or provide additional Treasury securities to the counterparty.

For the year ended September 30, 2015, the average amount of reverse repurchase agreements outstanding and the daily weighted average interest rate for the Master Portfolio were $984,797,900 and (0.105)%, respectively.

Borrowed bond agreements, reverse repurchase transactions and treasury roll transactions are entered into by the Master Portfolio under Master Repurchase Agreements (each, an “MRA”), which permit the Master Portfolio, under certain circumstances, including an event of default (such as bankruptcy or insolvency), to offset payables and/or receivables under the MRA with collateral held and/or posted to the counterparty and create one single net payment due to or from the Master Portfolio. With borrowed bond agreements reverse repurchase transactions and treasury roll transactions, typically the Master Portfolio and the counterparties are permitted to sell, re-pledge, or use the collateral associated with the transaction. Bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against such a right of offset in the event of the MRA counterparty’s bankruptcy or insolvency. Pursuant to the terms of the MRA, the Master Portfolio receives or posts securities as collateral with a market value in excess of the repurchase price to be paid or received by the Master Portfolio upon the maturity of the transaction. Upon a bankruptcy or insolvency of the MRA counterparty, the Master Portfolio is considered an unsecured creditor with respect to excess collateral and, as such, the return of excess collateral may be delayed.

¹  Included in Investments at value-unaffiliated in the Consolidated Statement of Assets and Liabilities.

²  Includes accrued interest on borrowed bonds in the amount of $584,113 which is included in interest expense payable in the Consolidated Statement of Assets and Liabilities.

³  Net collateral with a value of $1,957,357,000 has been pledged/received in connection with open reverse repurchase agreements. Excess of net collateral pledged to the individual counterparty is not shown for financial reporting purposes.

⁴  Net exposure represents the net receivable (payable) that would be due from/to the counterparty in the event of default.

When the Master Portfolio enters into an MRA and an ISDA Master Agreement and/or Master Securities Lending Agreements (each, an “MSLA”) with the same counterparty, the agreements may contain a set-off provision allowing a fund to offset a net amount payable with a net amount receivable upon default of the counterparty. Bankruptcy or insolvency laws of a particular jurisdiction may restrict or prohibit the right of offset in bankruptcy, insolvency or other events. For example, regardless of the contractual rights included in an MRA, such laws may prohibit the Master Portfolio from setting off amounts owed to a defaulting counterparty under an MRA against amounts owed to the Master Portfolio by affiliates of the defaulting counterparty. However, the insolvency regimes of many jurisdictions generally permit set-off of simultaneous payables and receivables with the same legal entity under certain types of financial contracts. These rules would apply upon a default of the legal entity, regardless of the existence of a contractual set-off right in those contracts.

In the event the counterparty of securities under an MRA files for bankruptcy or becomes insolvent, the Master Portfolio’s use of the proceeds from the agreement may be restricted while the counterparty, or its trustee or receiver, determines whether or not to enforce the Master Portfolio’s obligation to repurchase the securities.

Short Sales (Borrowed Bonds): The Master Portfolio may enter into short sale transactions in which the Master Portfolio sells a security it does not hold in anticipation of a decline in the market price of that security. When the Master Portfolio makes a short sale, it will borrow the security sold short (borrowed bond) and deliver the security to the counterparty to which it sold the security short. An amount equal to the proceeds 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 market value of the short sale. The Master Portfolio is required to repay the counterparty interest on the security sold short, which is shown as interest expense in the Consolidated Statement of Operations. The Master Portfolio is exposed to market risk based on the amount, if any, that the market value of the security increases beyond the market value at which the position was sold. Thus, a short sale of a security involves the risk that instead of declining, the price of the security sold short will rise. The short sale of securities involves the possibility of a theoretically unlimited loss since there is a theoretically unlimited potential for the market price of the security sold short to increase. A gain, limited to the price at which the Master Portfolio sold the security short, or a loss, unlimited as to the dollar amount, will be recognized upon the termination of a short sale if the market price is either less than or greater than the proceeds originally received. There is no assurance the Master Portfolio will be able to close out a short position at a particular time or at an acceptable price.

Short Sales (Investments Sold Short): The Master Portfolio may enter into short sale transactions in which the Master Portfolio sells a security it does not hold in anticipation of a decline in the market price of that security. When the Master Portfolio makes a short sale, it will borrow the security sold short from a broker/counterparty and deliver the security to the purchaser. To close out a short position, the Master Portfolio delivers the same security

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

to the broker and records a liability to reflect the obligation to return the security to the broker. The amount of the liability is subsequently marked-to-market to reflect the market value of the short sale. the Master Portfolio maintains a segregated account of securities or deposits cash with the broker-dealer as collateral for the short sales. Cash deposited with the broker is recorded as an asset in the Consolidated Statements of Assets and Liabilities. Securities segregated as collateral are denoted in the Consolidated Schedule of Investments. The Master Portfolio may pay a financing fee for the difference between the market value of the short position and the cash collateral deposited with the broker which would be recorded as interest expense. The Master Portfolio is required to repay the counterparty any dividends received on the security sold short, which is shown as dividend expense in the Consolidated Statements of Operations. The Master Portfolio may pay a fee on the assets borrowed from the counterparty, which is shown as stock loan fees in the Consolidated Statements of Operations. The Master Portfolio is exposed to market risk based on the amount, if any, that the market value of the security increases beyond the market value at which the position was sold. Thus, a short sale of a security involves the risk that instead of declining, the price of the security sold short will rise. The short sale of securities involves the possibility of a theoretically unlimited loss since there is a theoretically unlimited potential for the market price of the security sold short to increase. A gain, limited to the price at which the Master Portfolio sold the security short, or a loss, unlimited as to the dollar amount, will be recognized upon the termination of a short sale if the market price is either less than or greater than the proceeds originally received. There is no assurance that the Master Portfolio will be able to close out a short position at a particular time or at an acceptable price.

5. Derivative Financial Instruments:

The Master Portfolio engages in various portfolio investment strategies using derivative contracts both to increase the returns of the Master Portfolio and/or to manage its exposure to certain risks such as credit risk, equity risk, interest rate risk or foreign currency exchange rate risk or other risk (e.g. inflation risk). These contracts may be transacted on an exchange or OTC.

Financial Futures Contracts: The Master Portfolio invests in long and/or short positions in financial futures contracts and options on financial futures contracts to gain exposure to, or economically hedge against, changes in interest rates (interest rate risk) or changes in the value of equity securities (equity risk). Financial futures contracts are agreements between the Master Portfolio and a counterparty to buy or sell a specific quantity of an underlying instrument at a specified price and at a specified date. Depending on the terms of the particular contract, financial futures contracts are settled either through physical delivery of the underlying instrument on the settlement date or by payment of a cash settlement amount on the settlement date.

Upon entering into a financial futures contract, the Master Portfolio is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on a contract’s size and risk profile. The initial margin deposit must then be maintained at an established level over the life of the contract. Securities deposited as initial margin are designated on the Consolidated Schedule of Investments and cash deposited, if any, is recorded on the Consolidated Statements of Assets and Liabilities as cash pledged for financial futures contracts. 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. Variation margin is recorded by the Master Portfolio as unrealized appreciation or depreciation and, if applicable, as a receivable or payable for variation margin in the Consolidated Statements of Assets and Liabilities.

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. The use of financial futures contracts involves the risk of an imperfect correlation in the movements in the price of financial futures contracts or interest rates and the underlying assets.

Forward Foreign Currency Exchange Contracts: The Master Portfolio enters into forward foreign currency exchange contracts as an economic hedge against either specific transactions or portfolio instruments or to obtain exposure to, or hedge exposure away from, foreign currencies (foreign currency exchange rate risk). A forward foreign currency exchange contract is an agreement between two parties to buy and sell a currency at a set exchange rate on a future date. Forward foreign currency exchange contracts, when used by the Master Portfolio, help to manage the overall exposure to the currencies in which some of the investments held by the Master Portfolio is denominated. Non-deliverable forward foreign currency exchange contracts are settled with the counterparty in cash without the delivery of foreign currency. 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. The use of forward foreign currency exchange contracts involves the risk that the value of a forward foreign currency exchange contract changes unfavorably due to movements in the value of the referenced foreign currencies.

Options: The Master Portfolio purchases and writes call and put options to increase or decrease its exposure to underlying instruments (including credit risk and/or equity risk) and/or, in the case of options written, to generate gains from options premiums. A call option gives the purchaser (holder) of the option the right (but not the obligation) to buy, and obligates the seller (writer) to sell (when the option is exercised) the underlying instrument at the exercise or strike price at any time or at a specified time during the option period. A put option gives the holder the right to sell and obligates the writer to buy the underlying instrument at the exercise or strike price at any time or at a specified time during the option period. When the Master Portfolio purchases (writes) an option, an amount equal to the premium paid (received) by the Master Portfolio is reflected as an asset

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 95

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

(liability). The amount of the asset (liability) is subsequently marked-to-market to reflect the current market value of the option purchased (written). When an instrument 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 instrument acquired or deducted from (or added to) the proceeds of the instrument 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 gain or loss to the extent the cost of the closing transaction exceeds the premiums received or paid). When the Master Portfolio writes a call option, such option is “covered,” meaning that the Master Portfolio holds the underlying instrument subject to being called by the option counterparty. When the Master Portfolio writes a put option, such option is covered by cash in an amount sufficient to cover the obligation.

Options on swaps (“swaptions”) are similar to options on securities except that instead of selling or purchasing the right to buy or sell a security, the writer or purchaser of the swaptions is granting or buying the right to enter into a previously agreed upon interest rate or credit default swap agreement (interest rate risk and/or credit risk) at any time before the expiration of the option.

The Master Portfolio also purchases or sells 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 or to gain exposure to foreign currencies (foreign currency exchange rate risk). When foreign currency is purchased or sold through an exercise of a foreign currency option, the related premium paid (or received) is added to (or deducted from) the basis of the foreign currency acquired or deducted from (or added to) the proceeds of the foreign currency sold (receipts from the foreign currency purchased). Such transactions may be effected with respect to hedges on non-U.S. dollar denominated instruments owned by the Master Portfolio but not yet delivered, or committed or anticipated to be purchased by the Master Portfolio.

The Master Portfolio may also purchase and write a variety of options with non-standard payout structures or other features (“barrier options”). Barrier options are generally traded OTC. The Master Portfolio may invest in various types of barrier options including up-and-out options. Up-and-out options expire worthless if the price of the underlying instrument increases beyond a predetermined barrier price level prior to the option’s expiration date. Barrier options may also be referred to as knockout options. In a reverse knockout option, the option expires worthless if the price of the underlying instrument decreases beyond a predetermined barrier price level prior to the option’s expiration date.

In purchasing and writing options, the Master Portfolio bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Master Portfolio may not be able to enter into a closing transaction due to an illiquid market. Exercise of a written option could result in the Master Portfolio purchasing or selling a security when it otherwise would not, or at a price different from the current market value.

The Master Portfolio invests in structured options to increase or decrease its exposure to an underlying index or group of securities (equity risk). These structured options are European-style options and may consist of single or multiple OTC options which are priced as a single security. European-style options may only be exercised at the expiration date, but may be transferred/sold prior to the expiration date. The value of a structured option may either increase or decrease with the underlying index or group of securities, depending on the combination of options used. Structured options are issued in units whereby each unit represents a structure based on the specific index with an initial reference strike price. One type of structure involves the combination of selling a put while buying a call on a specific index. This option would rise in value as the underlying index increases and fall in value as the underlying index decreases. Alternatively, another structure involves the sale of a call and the purchase of a put. This option structure would rise in value as the underlying index decreases and fall in value as the underlying index increases. Upon the exercise of the structured option, the Master Portfolio will receive a payment from, or be required to remit a payment to the counterparty, depending on the value of the underlying index at exercise.

Swaps: The Master Portfolio enters into swap agreements in which the Master Portfolio and a counterparty agree either to make periodic net payments on a specified notional amount or a net payment upon termination. Swap agreements are privately negotiated in the OTC market and may be entered into as a bilateral contract (“OTC swaps”) or centrally cleared (“centrally cleared swaps”). Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation).

For OTC swaps, any upfront premiums paid are recorded as assets and any upfront fees received are recorded as liabilities and are shown as swap premiums paid and swap premiums received, respectively, in the Consolidated Statements of Assets and Liabilities and amortized over the term of the OTC swap. Payments received or made by the Master Portfolio for OTC swaps are recorded in the Consolidated Statements of Operations as realized gains or losses, respectively. When an OTC swap is terminated, the Master Portfolio will record a realized gain or loss equal to the difference between the proceeds from (or cost of) the closing transaction and the Master Portfolio’s basis in the contract, if any. Generally, the basis of the contract is the premium received or paid.

In a centrally cleared swap, immediately following execution of the swap agreement, the swap agreement is novated to a central counterparty (the “CCP”) and the Master Portfolio’s counterparty on the swap agreement becomes the CCP. The Master Portfolio is required to interface with the CCP through a broker. Upon entering into a centrally cleared swap, the Master Portfolio is required to deposit initial margin with the broker in the form of cash or securities in an amount that varies depending on the size and risk profile of the particular swap. Securities deposited as initial margin are designated on the Consolidated Schedules of Investments and cash deposited is recorded on the Consolidated Statements of Assets and Liabilities as

96 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

cash pledged for centrally cleared swaps. The daily change in valuation of centrally cleared swaps is recorded as a receivable or payable for variation margin in the Consolidated Statements of Assets and Liabilities. Payments received from (paid to) the counterparty, including at termination, are recorded as realized gain (loss) in the Consolidated Statements of Operations.

Swap transactions involve, to varying degrees, elements of interest rate, credit and market risk in excess of the amounts recognized in the Consolidated Statements of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in interest rates and/or market values associated with these transactions.

• Credit default swaps — The Master Portfolio enters into credit default swaps to manage its exposure to the market or certain sectors of the market, to reduce its risk exposure to defaults of corporate and/or sovereign issuers or to create exposure to corporate and/or sovereign issuers to which it is not otherwise exposed (credit risk). The Master Portfolio may either buy or sell (write) credit default swaps on single-name issuers (corporate or sovereign), a combination or basket of single-name issuers or traded indexes. Credit default swaps on single-name issuers are agreements in which the protection buyer pays fixed periodic payments to the seller in consideration for a guarantee from the protection seller to make a specific payment should a negative credit event take place with respect to the referenced entity (e.g., bankruptcy, failure to pay, obligation accelerators, repudiation, moratorium or restructuring). Credit default swaps on traded indexes are agreements in which the buyer pays fixed periodic payments to the seller in consideration for a guarantee from the seller to make a specific payment should a write-down, principal or interest shortfall or default of all or individual underlying securities included in the index occur. As a buyer, if an underlying credit event occurs, the Master Portfolio will either (i) receive from the seller an amount equal to the notional amount of the swap and deliver the referenced security or underlying securities comprising the index, or (ii) receive a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising the index. As a seller (writer), if an underlying credit event occurs, the Master Portfolio will either pay the buyer an amount equal to the notional amount of the swap and take delivery of the referenced security or underlying securities comprising the index or pay a net settlement of cash equal to the notional amount of the swap less the recovery value of the security or underlying securities comprising the index.

• Total return swaps — The Master Portfolio enters into total return swaps to obtain exposure to a portfolio of long and short securities without owning such securities. Under the terms of an agreement, the swap is designed to function as a portfolio of direct investments in long and short equity. This means that the Master Portfolio has the ability to trade in and out of long and short positions within the swap and will receive the economic benefits and risks equivalent to direct investment in these positions such as: capital appreciation (depreciation), corporate actions and dividends received and paid, all of which are reflected in the swap value. The swap value also includes interest charges and credits (“financing fees”) related to the notional values of the long and short positions and cash balances within the swap. These interest charges and credits are based on a specified benchmark rate plus or minus a specified spread determined based upon the country and/or currency of the positions in the portfolio. A change in the market value of a total return swap is included in change in unrealized appreciation (depreciation) on swaps in the Consolidated Statements of Operations. Positions within the swap are reset periodically, and financing fees are reset monthly. During a reset, any unrealized gains (losses) on positions and accrued financing fees become available for cash settlement between the Master Portfolio and the swap counterparty. The amounts that are available for cash settlement are included in realized gains (losses) on swaps in the Consolidated Statements of Operations. Cash settlement in and out of the swap may occur at a reset date or any other date, at the discretion of the Master Portfolio and the counterparty, over the life of the agreement, and is generally determined based on limits and thresholds established as part of an ISDA Master Agreement between the Master Portfolio and the counterparty. Certain swaps have no stated expiration and can be terminated by either party at any time.

• Interest rate swaps — The Master Portfolio enters into interest rate swaps to gain or reduce exposure to interest rates or to manage duration, the yield curve or interest rate risk by economically hedging the value of the fixed rate bonds, which may decrease when interest rates rise (interest rate risk). Interest rate swaps are agreements in which one party pays a stream of interest payments, either fixed or floating, for another party’s stream of interest payments, either fixed or floating, on the same notional amount for a specified period of time. In more complex swaps, the notional principal amount may decline (or amortize) over time.

• Currency swaps — The Master Portfolio enters into cross-currency swaps to gain or reduce exposure to foreign currencies or as an economic hedge against either specific transactions or portfolio instruments (foreign currency exchange rate and/or interest rate risk). Currency swaps are interest rate swaps in which one party pays a stream of interest payments, either fixed or floating, in exchange for another party’s stream of interest payments, either fixed or floating, based on the notional amounts of two different currencies. The notional amounts are typically determined based on the spot exchange rates at the inception of the trade. Currency swaps may also involve an exchange of notional amounts at the start, during and/or at expiration of the contract, either at the current spot rate or another specified rate.

• Forward interest rate swaps — The Master Portfolio may enter into forward interest rate swaps and forward total return swaps. In a forward swap, the Master Portfolio and the counterparty agree to make either periodic net payments beginning on a specified future effective date or a net payment at termination, unless terminated earlier.

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

Counterparty Credit Risk: A derivative contract may suffer a mark-to-market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract.

The Master Portfolio’s risk of loss from counterparty credit risk on OTC derivatives is generally limited to the aggregate unrealized gain netted against any collateral held by the Master Portfolio. For OTC options purchased, the Master Portfolio bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by the Master Portfolio should the counterparty fail to perform under the contracts. Options written by the Master Portfolio do not typically give rise to counterparty credit risk, as options written generally obligate the Master Portfolio, and not the counterparty, to perform, though the Master Portfolio may be exposed to counterparty credit risk with respect to options written to the extent the Master Portfolio deposits collateral with its counterparty to a written option.

With exchange-traded options purchased and futures and centrally cleared swaps, there is less counterparty credit risk to the Master Portfolio since the exchange or clearinghouse, as counterparty to such instruments, guarantees against a possible default. The clearinghouse stands between the buyer and the seller of the contract; therefore, credit risk is limited to failure of the clearinghouse. While offset rights may exist under applicable law, the Master Portfolio does not have a contractual right of offset against a clearing broker or clearinghouse in the event of a default (including the bankruptcy or insolvency) of the clearing broker or clearinghouse. Additionally, credit risk exists in exchange-traded futures and centrally cleared swaps with respect to initial and variation margin that is held in a clearing broker’s customer accounts. While clearing brokers are required to segregate customer margin from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of margin held by the clearing broker for all its clients, typically the shortfall would be allocated on a pro rata basis across all the clearing broker’s customers, potentially resulting in losses to the Master Portfolio.

In order to better define its contractual rights and to secure rights that will help the Master Portfolio mitigate its counterparty risk, the Master Portfolio may enter into an ISDA Master Agreement or similar agreement with its counterparties. An ISDA Master Agreement is a bilateral agreement between the Master Portfolio and a counterparty that governs certain OTC derivatives and typically contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Master Portfolio may, under certain circumstances, offset with the counterparty certain derivative financial instruments’ payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default including the bankruptcy or insolvency of the counterparty. Bankruptcy or insolvency laws of a particular jurisdiction may restrict or prohibit the right of offset in bankruptcy, insolvency or other events. In addition, certain ISDA Master Agreements allow counterparties to terminate derivative contracts prior to maturity in the event the Master Portfolio’s net assets decline by a stated percentage or the Master Portfolio fails to meet the terms of its ISDA Master Agreements. The result would cause the Master Portfolio to accelerate payment of any net liability owed to the counterparty.

Collateral Requirements: For derivatives traded under an ISDA Master Agreement, the collateral requirements are typically calculated by netting the mark-to-market amount for each transaction under such agreement and comparing that amount to the value of any collateral currently pledged by the Master Portfolio and the counterparty.

Cash collateral that has been pledged to cover obligations of the Master Portfolio and cash collateral received from the counterparty, if any, is reported separately on the Consolidated Statements of Assets and Liabilities as cash pledged as collateral and cash received as collateral, respectively. Non-cash collateral pledged by the Master Portfolio, if any, is noted in the Consolidated Schedules of Investments. Generally, the amount of collateral due from or to a party has to exceed a minimum transfer amount threshold (typically either $250,000 or $500,000) before a transfer is required, which is determined at the close of business of the Master Portfolio. Any additional required collateral is delivered to/pledged by the Master Portfolio on the next business day. Typically, the Master Portfolio and its counterparties are not permitted to sell, re-pledge or use the collateral they receive. To the extent amounts due to the Master Portfolio from its counterparties are not fully collateralized, the Master Portfolio bears the risk of loss from counterparty non-performance. Likewise, to the extent the Master Portfolio has delivered collateral to a counterparty and stands ready to perform under the terms of its agreements with such counterparty, the Master Portfolio bears the risk of loss from a counterparty in the amount of the value of the collateral in the event the counterparty fails to return such collateral.

For financial reporting purposes, the Master Portfolio does not offset derivative assets and derivative liabilities that are subject to netting arrangements, if any, in the Consolidated Statements of Assets and Liabilities.

6. Investment Advisory Agreement and Other Transactions with Affiliates:

The PNC Financial Services Group, Inc. is the largest stockholder and an affiliate of BlackRock, Inc. (“BlackRock”) for 1940 Act purposes.

The Master LLC, on behalf of the Master Portfolio, entered into an Investment Advisory Agreement with BlackRock Advisors, LLC (the “Manager”), the Master LLC’s investment advisor, an indirect, wholly owned subsidiary of BlackRock, to provide investment advisory and administration services. The Manager is responsible for the management of the Master Portfolio’s portfolio and provides the personnel, facilities, equipment and certain other

98 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

services necessary to the operations of the Master Portfolio. For such services, the Master Portfolio pays the Manager a monthly fee based on the percentage of the Master Portfolio’s average daily net assets at the following annual rates for the period indicated:

	Investment Advisory Fee
Average Daily Net Assets	Period October 1, 2014 to November 20, 2014	Period November 21, 2014 to September 30, 2015
First $250 Million	0.20%	0.16%
$250 Million - $500 Million	0.15%	0.12%
$500 Million - $750 Million	0.10%	0.08%
Greater than $750 Million	0.05%	0.05%

The Manager voluntarily agreed to waive its investment advisory fees by the amount of investment advisory fees the Master Portfolio pays to the Manager indirectly through its investment in affiliated money market funds. This amount is included in fees waived by the Manager in the Consolidated Statement of Operations. However, the Manager does not waive its investment advisory fees by the amount of investment advisory fees paid in connection with the Master Portfolio’s investments in other affiliated investment companies, if any. This amount is shown as fees waived by the Manager in the Consolidated Statement of Operations.

The Manager provides investment management and other services to the Subsidiary. The Manager does not receive separate compensation from the Subsidiary for providing investment management or administrative services. However, the Master Portfolio pays the Manager based on the Master Portfolio’s net assets which includes the assets of the Subsidiary.

The Manager, on behalf of the Master Portfolio, entered into sub-advisory agreements with BlackRock International Limited (“BIL”) and BlackRock (Singapore) Limited (“BRS”), each an affiliate of the Manager. The Manager pays BIL and BRS for services they provide, a monthly fee that is a percentage of the investment advisory fees paid by the Master Portfolio to the Manager.

For the year ended September 30, 2015, the Master LLC reimbursed the Manager $49,950 for certain accounting services, which is included in accounting services in the Consolidated Statement of Operations.

During the year ended September 30, 2015, the Portfolio received a reimbursement of $668 from an affiliate, which is included in capital transactions in the Consolidated Statements of Changes in Net Assets, relating to a processing error.

Certain officers and/or directors of the Master LLC are officers and/or directors of BlackRock or its affiliates.

The Master Portfolio may purchase securities from, or sell securities to, an affiliated fund provided the affiliation is due solely to having a common investment advisor, common officers, or common trustees. For the year ended September 30, 2015, the purchase and sale transactions with an affiliated fund in compliance with Rule 17a-7 under the 1940 Act were $14,316,353 and $2,909,496, respectively.

7. Purchases and Sales:

For the year ended September 30, 2015, purchases and sales of investments, including paydown and mortgage dollar rolls and excluding short-term securities, were as follows:

Purchases
Non-U.S. Government Securities	$	50,978,225,843
U.S. Government Securities		27,916,061,461
Total Purchases	$	78,894,287,304
Sales

8. Income Tax Information:

The Master Portfolio is classified as a partnership for federal income tax purposes. As such, each investor in the Master Portfolio is treated as the owner of its proportionate share of net assets, income, expenses and realized and unrealized gains and losses of the Master Portfolio. Therefore, no federal

BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015 99

Notes to Consolidated Financial Statements (continued) Master Total Return Portfolio

income tax provision is required. 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 of 1986, as amended.

The Master Portfolio files U.S. federal and various state and local tax returns. No income tax returns are currently under examination. The statute of limitations on the Master Portfolio’s U.S. federal tax returns remains open for each of the four years ended September 30, 2015. The statutes of limitations on Master Portfolio’s state and local tax returns may remain open for an additional year depending upon the jurisdiction.

Management has analyzed tax laws and regulations and their application to the Master Portfolio as of September 30, 2015, inclusive of the open tax return years, and does not believe there are any uncertain tax positions that require recognition of a tax liability in the Master Portfolio’s financial statements.

As of period end, gross unrealized appreciation and depreciation based on cost for federal income tax purposes were as follows:

Tax cost	$	12,644,284,273
Gross unrealized appreciation	$	81,576,027
Gross unrealized depreciation		(153,780,501	)
Net unrealized depreciation	$	(72,204,474	)

9. Bank Borrowings:

The Master LLC, on behalf of the Master Portfolio, along with certain other funds managed by the Manager and its affiliates (“Participating Funds”), is a party to a 364-day, $2.1 billion credit agreement with a group of lenders, under which the Master Portfolio may borrow to fund shareholder redemptions. Excluding commitments designated for certain individual funds, the Participating Funds, including the Master Portfolio, can borrow up to an aggregate commitment amount of $1.6 billion, subject to asset coverage and other limitations as specified in the agreement. The credit agreement has the following terms: a fee of 0.06% per annum on unused commitment amounts and interest at a rate equal to the higher of (a) one-month LIBOR (but, in any event, not less than 0.00%) on the date the loan is made plus 0.80% per annum or (b) the Fed Funds rate (but, in any event, not less than 0.00%) in effect from time to time plus 0.80% per annum on amounts borrowed. The agreement expires in April 2016 unless extended or renewed. Prior to November 25, 2014, the aggregate commitment amount was $1.1 billion, of which the Participating Funds, including the Master Portfolio, could borrow up to $650 million at any time outstanding, subject to asset coverage and other limitations as specified in the agreement. Participating Funds paid administration, legal and arrangement fees, which are included in miscellaneous expenses in the Statements of Operations, and along with commitment fees, were allocated among such funds based upon portions of the aggregate commitment available to them and relative net assets of Participating Funds. During the year ended September 30, 2015, the Master Portfolio did not borrow under the credit agreement.

10. Principal Risks:

In the normal course of business, the Master Portfolio invests in securities and enters into transactions where risks exist due to fluctuations in the market (market risk) or failure of the issuer of a security to meet all its obligations, including to pay principal and interest when due (issuer credit risk). The value of securities held by the Master Portfolio may decline in response to certain events, including those directly involving the issuers whose securities are owned by the Master Portfolio; conditions affecting the general economy; overall market changes; local, regional or global political, social or economic instability; and currency and interest rate and price fluctuations. Similar to issuer credit risk, the Master Portfolio may be exposed to counterparty credit risk, or the risk that an entity with which the Master Portfolio has unsettled or open transactions may fail to or be unable to perform on its commitments. The Master Portfolio manages counterparty credit risk by entering into transactions only with counterparties that the Manager believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties. Financial assets, which potentially expose the Master Portfolio to market, issuer and counterparty credit risks, consist principally of financial instruments and receivables due from counterparties. The extent of the Master Portfolio’s exposure to market, issuer and counterparty credit risks with respect to these financial assets is generally approximated by their value recorded in the Consolidated Statements of Assets and Liabilities, less any collateral held by the Master Portfolio.

The Master Portfolio invests a significant portion of its assets in fixed income securities and/or uses derivatives tied to the fixed-income markets. See the Consolidated Schedules of Investments for these securities and/or derivatives. Changes in market interest rates or economic conditions, may affect the value and/or liquidity of such investments. Interest rate risk is the risk that prices of bonds and other fixed-income securities will increase as interest rates fall and decrease as interest rates rise. The Master Portfolio may be subject to a greater risk of rising interest rates due to the current period of historically low rates.

The Master Portfolio 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. Investment percentages in these securities are presented in the Consolidated Schedule of Investments. Changes in economic conditions, including delinquencies and/or defaults on assets underlying these securities, can affect the value, income and/or liquidity of such positions.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of Master Bond LLC and Investors of Master Total Return Portfolio:

We have audited the accompanying consolidated statement of assets and liabilities, including the consolidated schedule of investments, of Master Total Return Portfolio (the “Master Portfolio”), a series of Master Bond LLC, as of September 30, 2015, and the related consolidated statements of operations for the year then ended, the consolidated statements of changes in net assets for each of the two years in the period then ended, and the consolidated financial highlights for each of the four years in the period then ended, and the financial highlights for the other period presented. These financial statements and financial highlights are the responsibility of the Master Portfolio’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 Portfolio is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit 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 Portfolio’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, 2015, by correspondence with the custodian, brokers and agent banks; when replies were not received from brokers and agent banks, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such financial statements and financial highlights referred to above present fairly, in all material respects, the consolidated financial position of Master Total Return Portfolio as of September 30, 2015, the consolidated results of its operations for the year then ended, the consolidated changes in its net assets for each of the two years in the period then ended, and the consolidated financial highlights for each of the four years in the period then ended, and its financial highlights for the other period presented, in conformity with accounting principles generally accepted in the United States of America.

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements

The Board of Directors of Master Bond LLC (the “Master LLC”) and the Board of Directors of BlackRock Bond Fund, Inc. (the “Corporation”) met in person on April 14, 2015 (the “April Meeting”) and May 12-13, 2015 (the “May Meeting”) to consider the approval of the investment advisory agreements (collectively, the “Advisory Agreements”) between the Master LLC, on behalf of Master Total Return Portfolio (the “Master Fund”), and BlackRock Advisors, LLC (the “Manager”), and between the Corporation, on behalf of BlackRock Total Return Fund (the “Feeder Fund” and, together with the Master Fund, the “Funds” and each, a “Fund”), and the Manager, the Master Fund’s and the Feeder Fund’s investment advisor. The Board of Directors of each of the Master LLC and the Corporation also considered the approval of the sub-advisory agreements (collectively, the “Sub-Advisory Agreements”) between the Manager and each of (a) BlackRock International Limited; and (b) BlackRock (Singapore) Limited (collectively, the “Sub-Advisors”), with respect to each of the Master Fund and the Feeder Fund. The Feeder Fund is a “feeder” fund that invests all of its investable assets in the Master Fund. Accordingly, the Board of Directors of the Corporation also considered the approval of the Advisory Agreement and the Sub-Advisory Agreements with respect to the Master LLC. The Manager and the Sub-Advisors are referred to herein as “BlackRock.” The Advisory Agreements and the Sub-Advisory Agreements are referred to herein as the “Agreements.” For simplicity: (a) the Board of Directors of the Master LLC and the Board of Directors of the Corporation are referred to herein collectively as the “Board,” and the members are referred to as “Board Members;” and (b) the shareholders of the Feeder Fund and the interest holders of the Master Fund are referred to as “shareholders.”

Activities and Composition of the Board

On the date of the April and May Meetings, the Board consisted of thirteen individuals, ten of whom were not “interested persons” of the Master LLC or the Corporation as defined in the Investment Company Act of 1940, as amended (the “1940 Act”) (the “Independent Board Members”). One of the Board Members is a non-management interested Board Member by virtue of his former positions with BlackRock, Inc. and its affiliates. The Board Members are responsible for the oversight of the operations of the Master Fund or the Feeder Fund, as pertinent, and perform the various duties imposed on the directors of investment companies by the 1940 Act. The Independent Board Members have retained independent legal counsel to assist them in connection with their duties. The Chairman of the Board is an Independent Board Member. The Board has established five standing committees: an Audit Committee, a Governance and Nominating Committee, a Compliance Committee, a Performance Oversight Committee and an Executive Committee, each of which is chaired by an Independent Board Member and composed of Independent Board Members (except for the Performance Oversight Committee and the Executive Committee, each of which also has one interested Board Member).

The Agreements

Pursuant to the 1940 Act, the Board is required to consider the continuation of the Agreements on an annual basis. The Board has four quarterly meetings per year, each extending over two days, a fifth one-day meeting to consider specific information surrounding the consideration of renewing the Agreements and additional in-person and telephonic meetings as needed. In connection with this year-long deliberative process, the Board assessed, among other things, the nature, extent and quality of the services provided to the Master Fund and the Feeder Fund by BlackRock, BlackRock’s personnel and affiliates, including (as applicable): investment management services; administrative and shareholder services; the oversight of fund service providers; marketing services; risk oversight; compliance and ability to meet applicable legal and regulatory requirements.

The Board, acting directly and through its committees, considers at each of its meetings, and from time to time as appropriate, factors that are relevant to its annual consideration of the renewal of the Agreements, including the services and support provided by BlackRock to the Master Fund, the Feeder Fund and their shareholders. Among the matters the Board considered were: (a) investment performance for one-year, three-year, five-year and/or since inception periods, as applicable, against peer funds, applicable benchmark, and performance metrics, as applicable, as well as senior management’s and portfolio managers’ analysis of the reasons for any over-performance or underperformance relative to peers, benchmarks, and other performance metrics, as applicable; (b) fees, including advisory, administration, if applicable, and other amounts paid to BlackRock and its affiliates by the Master Fund and/or the Feeder Fund for services, such as marketing and distribution, call center and fund accounting; (c) the Master Fund’s and/or the Feeder Fund’s operating expenses and how BlackRock allocates expenses to the Master Fund and the Feeder Fund; (d) the resources devoted to, risk oversight of, and compliance reports relating to, implementation of the Master Fund’s and the Feeder Fund’s investment objective(s), policies and restrictions, and meeting new regulatory requirements; (e) the Master Fund’s and the Feeder Fund’s compliance with its compliance policies and procedures; (f) the nature, cost and character of non-investment management services provided by BlackRock and its affiliates; (g) BlackRock’s and other service providers’ internal controls and risk and compliance oversight mechanisms; (h) BlackRock’s implementation of the proxy voting policies approved by the Board; (i) execution quality of portfolio transactions; (j) BlackRock’s implementation of the Master Fund’s and/or the Feeder Fund’s valuation and liquidity procedures; (k) an analysis of management fees for products with similar investment mandates across the open-end fund, exchange-traded fund (“ETF”), closed-end fund and institutional account product channels, as applicable, and the similarities and differences between these products and the services provided as compared to the Master Fund and/or Feeder Fund; (l) BlackRock’s compensation methodology for its investment professionals and the incentives it creates, along with investment professionals’ investments in the fund(s) they manage; and (m) periodic updates on BlackRock’s business.

The Board has engaged in an ongoing strategic review with BlackRock of opportunities to consolidate funds and of BlackRock’s commitment to investment performance. BlackRock also furnished information to the Board in response to specific questions. These questions covered issues such as: BlackRock’s profitability; investment performance; subadvisory and advisory relationships with other clients (including mutual funds sponsored by third

parties); the viability of specific funds; fund size and manager capacity; BlackRock’s research capabilities; portfolio managers’ investments in funds they manage; funds’ portfolio risk targets; and management fee levels and breakpoints. The Board further discussed with BlackRock: BlackRock’s management structure; portfolio turnover, execution quality and use of soft dollars; BlackRock’s portfolio manager compensation and performance accountability; marketing support for the funds; services provided to the funds by BlackRock affiliates; and BlackRock’s oversight of relationships with third party service providers.

Board Considerations in Approving the Agreements

The Approval Process: Prior to the April Meeting, the Board requested and received materials specifically relating to the Agreements. The Board is continuously engaged in a process with its independent legal counsel and BlackRock to review the nature and scope of the information provided to better assist its deliberations. The materials provided in connection with the April Meeting included (a) information independently compiled and prepared by Lipper, Inc. (“Lipper”) on fees and expenses of the Master Fund and the Feeder Fund, as applicable, as compared with a peer group of funds as determined by Lipper (“Expense Peers”) and the investment performance of the Feeder Fund as compared with a peer group of funds as determined by Lipper;¹ (b) information on the profits realized by BlackRock and its affiliates pursuant to the Agreements and a discussion of fall-out benefits to BlackRock and its affiliates; (c) a general analysis provided by BlackRock concerning investment management fees charged to other clients, such as institutional clients, sub-advised mutual funds, ETFs and closed-end funds, under similar investment mandates, as well as the performance of such other clients, as applicable; (d) review of non-management fees; (e) the existence, impact and sharing of potential economies of scale; (f) a summary of aggregate amounts paid by the Master Fund and/or the Feeder Fund to BlackRock; (g) sales and redemption data regarding the Feeder Fund’s shares; and (h) if applicable, a comparison of management fees to similar BlackRock open-end funds, as classified by Lipper.

At the April Meeting, the Board reviewed materials relating to its consideration of the Agreements. As a result of the discussions that occurred during the April Meeting, and as a culmination of the Board’s year-long deliberative process, the Board presented BlackRock with questions and requests for additional information. BlackRock responded to these requests with additional written information in advance of the May Meeting.

At the May Meeting, the Board of the Master LLC and the Corporation, including the Independent Board Members, approved the continuation of the respective Advisory Agreements between the Manager and each of the Master LLC, on behalf of the Master Fund, and the Corporation, on behalf of the Feeder Fund, and the respective Sub-Advisory Agreements between the Manager and the Sub-Advisors with respect to each of the Master Fund and the Feeder Fund, each for a one-year term ending June 30, 2016. The Board of the Corporation, including the Independent Board Members, also considered the continuation of the Agreements with respect to the Master LLC and found the Agreements to be satisfactory. In approving the continuation of the Agreements, the Board considered: (a) the nature, extent and quality of the services provided by BlackRock; (b) the investment performance of the Master Fund, the Feeder Fund and BlackRock; (c) the advisory fee and the cost of the services and profits to be realized by BlackRock and its affiliates from their relationship with the Master Fund and the Feeder Fund; (d) the Feeder Fund’s costs to investors compared to the costs of Expense Peers and performance compared to the relevant performance comparison as previously discussed; (e) the sharing of potential economies of scale; (f) fall-out benefits to BlackRock and its affiliates as a result of its relationship with the Master Fund and the Feeder Fund; and (g) other factors deemed relevant by the Board Members.

The Board also considered other matters it deemed important to the approval process, such as payments made to BlackRock or its affiliates relating to the distribution of Feeder Fund shares, securities lending and cash management, services related to the valuation and pricing of portfolio holdings of the Master Fund, direct and indirect benefits to BlackRock and its affiliates from their relationship with the Master Fund and the Feeder Fund and advice from independent legal counsel with respect to the review process and materials submitted for the Board’s review. The Board noted the willingness of BlackRock personnel to engage in open, candid discussions with the Board. The Board did not identify any particular information as determinative, and each Board Member may have attributed different weights to the various items considered.

A. Nature, Extent and Quality of the Services Provided by BlackRock: The Board, including the Independent Board Members, reviewed the nature, extent and quality of services provided by BlackRock, including the investment advisory services and the resulting performance of the Feeder Fund. Throughout the year, the Board compared the Feeder Fund’s performance to the performance of a comparable group of mutual funds, a relevant benchmark, and performance metrics, as applicable. The Board met with BlackRock’s senior management personnel responsible for investment activities, including the senior investment officers. The Board also reviewed the materials provided by the Master Fund’s portfolio management team discussing the Master Fund’s performance and the Master Fund’s investment objective(s), strategies and outlook.

The Board considered, among other factors, with respect to BlackRock: the number, education and experience of investment personnel generally and the Master Fund’s portfolio management team; BlackRock’s research capabilities; investments by portfolio managers in the funds they manage; portfolio trading capabilities; use of technology; commitment to compliance; credit analysis capabilities; risk analysis and oversight capabilities; and the approach to training and retaining portfolio managers and other research, advisory and management personnel. The Board engaged in a review of BlackRock’s compensation structure with respect to the Master Fund’s portfolio management team and BlackRock’s ability to attract and retain high-quality talent and create performance incentives.

¹ Funds are ranked by Lipper in quartiles, ranging from first to fourth, where first is the most desirable quartile position and fourth is the least desirable.

104 BLACKROCK TOTAL RETURN FUND OF BLACKROCK BOND FUND, INC. SEPTEMBER 30, 2015

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

In addition to advisory services, the Board considered the quality of the administrative and other non-investment advisory services provided to the Master Fund and the Feeder Fund. BlackRock and its affiliates provide the Master Fund and the Feeder Fund with certain administrative, shareholder and other services (in addition to any such services provided to the Master Fund and the Feeder Fund by third parties) and officers and other personnel as are necessary for the operations of the Master Fund and the Feeder Fund. In particular, BlackRock and its affiliates provide the Master Fund and the Feeder Fund with the following administrative services including, among others: (i) preparing disclosure documents, such as the prospectus, the summary prospectus (as applicable), the statement of additional information and periodic shareholder reports; (ii) oversight of daily accounting and pricing; (iii) overseeing and coordinating the activities of other service providers; (iv) organizing Board meetings and preparing the materials for such Board meetings; (v) providing legal and compliance support; (vi) furnishing analytical and other support to assist the Board in its consideration of strategic issues such as the merger, consolidation or repurposing of certain open-end funds; and (vii) performing other administrative functions necessary for the operation of the Master Fund and the Feeder Fund, such as tax reporting, fulfilling regulatory filing requirements and call center services. The Board reviewed the structure and duties of BlackRock’s fund administration, shareholder services, legal and compliance departments and considered BlackRock’s policies and procedures for assuring compliance with applicable laws and regulations.

B. The Investment Performance of the Master Fund, the Feeder Fund and BlackRock: The Board, including the Independent Board Members, also reviewed and considered the performance history of the Master Fund and the Feeder Fund, as applicable. The Board noted that the Feeder Fund’s investment results correspond directly to the investment results of the Master Fund. In preparation for the April Meeting, the Board worked with its independent legal counsel, BlackRock and Lipper to develop a template for, and was provided with, reports independently prepared by Lipper, which included a comprehensive analysis of the Feeder Fund’s performance. The Board also reviewed a narrative and statistical analysis of the Lipper data that was prepared by BlackRock. In connection with its review, the Board received and reviewed information regarding the investment performance of the Feeder Fund as compared to other funds in its applicable Lipper category. The Board was provided with a description of the methodology used by Lipper to select peer funds and periodically meets with Lipper representatives to review its methodology. The Board and its Performance Oversight Committee regularly review, and meet with Master Fund management to discuss, the performance of the Master Fund and the Feeder Fund, as applicable, throughout the year.

In evaluating performance, the Board recognized that the performance data reflects a snapshot of a period or as of a particular date and that selecting a different performance period could produce significantly different results. Further, the Board recognized that it is possible that long-term performance can be adversely affected by even one period of significant underperformance so that a single investment decision or theme has the ability to affect long-term performance disproportionately.

The Board noted that for each of the one-, three- and five-year periods reported, the Feeder Fund ranked in the first quartile against its Lipper Performance Universe.

C. Consideration of the Advisory/Management Fees and the Cost of the Services and Profits to be Realized by BlackRock and its Affiliates from their Relationship with the Master Fund and the Feeder Fund: .

The Board, including the Independent Board Members, reviewed the Master Fund’s/Feeder Fund’s contractual management fee rate compared with the other funds in the Feeder Fund’s Lipper category. The contractual management fee rate represents a combination of the advisory fee and any administrative fees, before taking into account any reimbursements or fee waivers. The Board also compared the Feeder Fund’s total expense ratio, as well as the Master Fund’s/Feeder Fund’s actual management fee rate, to those of other funds in the Feeder Fund’s Lipper category. The total expense ratio represents a fund’s total net operating expenses, including any 12b-1 or non 12b-1 service fees. The total expense ratio gives effect to any expense reimbursements or fee waivers that benefit a fund, and the actual management fee rate gives effect to any management fee reimbursements or waivers that benefit a fund. The Board considered the services provided and the fees charged by BlackRock to other types of clients with similar investment mandates, as applicable, including institutional accounts and sub-advised mutual funds.

The Board received and reviewed statements relating to BlackRock’s financial condition. The Board reviewed BlackRock’s profitability methodology and was also provided with a profitability analysis that detailed the revenues earned and the expenses incurred by BlackRock for services provided to the Master Fund and the Feeder Fund. The Board reviewed BlackRock’s profitability with respect to the Master Fund and the Feeder Fund, as applicable, and other funds the Board currently oversees for the year ended December 31, 2014 compared to available aggregate profitability data provided for the two prior years. The Board reviewed BlackRock’s profitability with respect to certain other U.S. fund complexes managed by the Manager and/or its affiliates. The Board reviewed BlackRock’s assumptions and methodology of allocating expenses in the profitability analysis, noting the inherent limitations in allocating costs among various advisory products. The Board recognized that profitability may be affected by numerous factors including, among other things, fee waivers and expense reimbursements by the Manager, the types of funds managed, precision of expense allocations and business mix. As a result, calculating and comparing profitability at individual fund levels is difficult.

Disclosure of Investment Advisory Agreements and Sub-Advisory Agreements (continued)

The Board noted that, in general, individual fund or product line profitability of other advisors is not publicly available. The Board reviewed BlackRock’s overall operating margin, in general, compared to that of certain other publicly-traded asset management firms. The Board considered the differences between BlackRock and these other firms, including the contribution of technology at BlackRock, BlackRock’s expense management, and the relative product mix.

In addition, the Board considered the cost of the services provided to the Master Fund and the Feeder Fund by BlackRock, and BlackRock’s and its affiliates’ profits relating to the management and distribution of the Master Fund and the Feeder Fund and the other funds advised by BlackRock and its affiliates. As part of its analysis, the Board reviewed BlackRock’s methodology in allocating its costs to the management of the Master Fund and the Feeder Fund. The Board may periodically receive and review information from independent third parties as part of its annual evaluation. BlackRock retained an independent third party to evaluate its cost allocation methodologies in the context of BlackRock’s 1940 Act Fund business. The Board considered the results of that evaluation in connection with BlackRock’s profitability reporting. The Board also considered whether BlackRock has the financial resources necessary to attract and retain high quality investment management personnel to perform its obligations under the Agreements and to continue to provide the high quality of services that is expected by the Board. The Board further considered factors including but not limited to BlackRock’s commitment of time, assumption of risk and liability profile in servicing the Master Fund and the Feeder Fund in contrast to what is required of BlackRock with respect to other products with similar investment mandates across the open-end fund, ETF, closed-end fund, sub-advised mutual fund and institutional account product channels, as applicable.

The Board noted that the Master Fund’s/Feeder Fund’s contractual management fee rate ranked in the first quartile, and that the actual management fee rate and Feeder Fund’s total expense ratio ranked in the second and first quartiles, respectively, relative to the Feeder Fund’s Expense Peers. The Board also noted that the Master Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of the Master Fund increases above certain contractually specified levels. The Board noted that BlackRock proposed, and the Board agreed to a contractual adjustment of the advisory fee to reduce the specified levels within the Master Fund’s breakpoint schedules. This adjustment was implemented on November 21, 2014. The Board further noted that the Feeder Fund has an advisory fee arrangement that includes breakpoints that adjust the fee rate downward as the size of the Feeder Fund increases above certain contractually specified levels. The Board noted that BlackRock proposed, and the Board agreed to, a contractual adjustment of the advisory fee to reduce the specified levels within the Feeder Fund’s breakpoint schedules. This adjustment was implemented on November 21, 2014. The Board noted that BlackRock has contractually agreed to a cap on the Feeder Fund’s total expenses as a percentage of the Feeder Fund’s average daily net assets on a class-by-class basis. The Board noted that BlackRock proposed, and the Board agreed to changes to the contractual expense cap on the Feeder Fund on a class-by-class basis, as applicable. These expense cap changes were implemented on November 21, 2014.

D. Economies of Scale: The Board, including the Independent Board Members, considered the extent to which economies of scale might be realized as the assets of the Master Fund and the Feeder Fund increase, as well as the existence of expense caps, as applicable. The Board also considered the extent to which the Master Fund and the Feeder Fund benefit from such economies and whether there should be changes in the advisory fee rate or breakpoint structure in order to enable the Master Fund and the Feeder Fund to participate in these economies of scale, for example through the use of revised breakpoints in the advisory fee based upon the asset level of the Master Fund and the Feeder Fund. In its consideration, the Board Members took into account the existence of any expense caps and further considered the continuation and/or implementation, as applicable, of such caps.

E. Other Factors Deemed Relevant by the Board Members: The Board, including the Independent Board Members, also took into account other ancillary or “fall-out” benefits that BlackRock or its affiliates may derive from their respective relationships with the Master Fund and the Feeder Fund, both tangible and intangible, such as BlackRock’s ability to leverage its investment professionals who manage other portfolios and risk management personnel, an increase in BlackRock’s profile in the investment advisory community, and the engagement of BlackRock’s affiliates as service providers to the Master Fund and the Feeder Fund, including for administrative, distribution, securities lending and cash management services. The Board also considered BlackRock’s overall operations and its efforts to expand the scale of, and improve the quality of, its operations. The Board also noted that BlackRock may use and benefit from third party research obtained by soft dollars generated by certain registered fund transactions to assist in managing all or a number of its other client accounts. The Board further noted that it had considered the investment by BlackRock’s funds in affiliated ETFs without any offset against the management fees payable by the funds to BlackRock.

In connection with its consideration of the Agreements, the Board also received information regarding BlackRock’s brokerage and soft dollar practices. The Board received reports from BlackRock which included information on brokerage commissions and trade execution practices throughout the year.

The Board noted the competitive nature of the open-end fund marketplace, and that shareholders are able to redeem their Feeder Fund shares if they believe that the Feeder Fund’s and/or the Master Fund’s fees and expenses are too high or if they are dissatisfied with the performance of the Feeder Fund.

Conclusion

The Board of each of the Master LLC and the Corporation, including the Independent Board Members, approved the continuation of the Advisory Agreements between the Manager and each of the Master LLC, on behalf of the Master Fund, and the Corporation, on behalf of the Feeder Fund, respectively, for a one-year term ending June 30, 2016, and the Sub-Advisory Agreements between the Manager and the Sub-Advisors with respect to each of the Master Fund and the Feeder Fund, respectively, for a one-year term ending June 30, 2016. Based upon its evaluation of all of the aforementioned factors in their totality, the Board of the Master LLC and the Corporation, including the Independent Board Members, was satisfied that the terms of the Agreements were fair and reasonable and in the best interest of the Master Fund and the Feeder Fund, as applicable, and their shareholders. The Board of the Corporation, including the Independent Board Members, also considered the continuation of the Agreements with respect to the Master Fund and found the Agreements to be satisfactory. In arriving at its decision to approve the Agreements, the Board did not identify any single factor or group of factors as all-important or controlling, but considered all factors together, and different Board Members may have attributed different weights to the various factors considered. The Independent Board Members were also assisted by the advice of independent legal counsel in making this determination. The contractual fee arrangements for the Master Fund and the Feeder Fund reflect the results of several years of review by the Board Members and predecessor Board Members, and discussions between such Board Members (and predecessor Board Members) and BlackRock. As a result, the Board Members’ conclusions may be based in part on their consideration of these arrangements in prior years.

(e)(1) Audit Committee Pre-Approval Policies and Procedures:

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 registrants on an annual basis require specific pre-approval by the Committee. The Committee also must approve other non-audit services provided to the registrants and those non-audit services provided to the Investment Adviser and Fund Service Providers that relate directly to the operations and the financial reporting of the registrants. 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”). The term of any general pre-approval is 12 months from the date of the pre-approval, unless the Committee provides for a different period. Tax or other non-audit services provided to the registrants which have a direct impact on the operations or financial reporting of the registrants will only be deemed pre-approved provided that any individual project does not exceed $10,000 attributable to the registrants or $50,000 per project. For this purpose, multiple projects will be aggregated to determine if they exceed the previously mentioned cost levels.

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. At this meeting, an analysis of such services is presented to the Committee for ratification. The Committee may delegate to the Committee Chairman the authority to approve the provision of and fees for any specific engagement of permitted non-audit services, including services exceeding pre-approved cost levels.

(e)(2) None of the services described in each of Items 4(b) through (d) were approved by the Committee pursuant to the de minimis exception in paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Not Applicable

(g) The aggregate non-audit fees paid to the accountant for services rendered by the accountant to the registrants, the Investment Adviser and the Fund Service Providers were:

Entity Name	Current Fiscal Year    End	Previous Fiscal Year    End
BlackRock Total Return Fund of BlackRock Bond Fund, Inc.	$15,402	$15,100
Master Total Return Portfolio of Master Bond LLC	$20,000	$13,500

	(h) The Committee has considered and determined that the provision of non-audit services that were rendered to the Investment Adviser and the Fund Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant’s independence.
