A Discussion With Your Fund's Portfolio Managers


We maintained a relatively conservative approach throughout the fiscal year,
looking to our yield curve positioning and duration profile as the key drivers
of relative performance.


How did the Fund perform during the fiscal year in light of the existing
market conditions?

For the 12-month period ended September 30, 2006, BlackRock Bond Fund of
BlackRock Bond Fund, Inc.'s (formerly Core Bond Portfolio of Merrill Lynch
Bond Fund, Inc.) Class A, Class B, Class C, Class I and Class R Shares had
total returns of +3.13%, +2.60%, +2.46%, +3.39% and +2.88%, respectively. For
the same period, the benchmark Lehman Brothers Aggregate Bond Index returned
+3.67%. (Fund results shown do not reflect sales charges and would be lower if
sales charges were included. Complete performance information can be found on
pages 6 and 7 of this report to shareholders.)

The past year was characterized by reasonable (albeit slowing) economic
growth, inflationary fears propagated by high energy prices and a continued
vigilant Federal Reserve Board (the Fed). The Fed raised interest rates
six times during the fiscal period before pausing on August 8, at last
acknowledging a slowdown in economic growth. At this point, the bond market
began to rally, with the benchmark 10-year Treasury yield falling as bond
prices correspondingly rose. Still, year-over-year, yields rose across the
curve and uncertainty prevailed as the markets struggled to interpret the
intentions of new Fed Chairman Ben Bernanke. On balance, it was a fairly
challenging period for fixed income investment.

The Fund's performance was influenced by our duration profile, yield curve
strategy and sector allocation decisions. In the first half of the year, we
had positioned the portfolio for a flattening yield curve, expressed largely
through an underexposure in the two-year - five-year part of the curve and an
above-average position in the 30-year area. Because bond prices move in the
opposite direction of yields, our strategy was correct as short-term yields
rose more than long-term yields. This effect reversed in March as the yield
curve began to resteepen, and we took the opportunity to begin moving away
from our flattening bias.

Similarly, we began the fiscal year with a relatively short duration but
started to limit that bias somewhat as the Fed approached its desired
"neutral" federal funds target. By mid-year, the Fund was positioned with a
slightly long duration, a posture we assumed as the 10-year Treasury yield
approached 5.25%. Our increasing duration hurt performance at times when
interest rates rose (as a shorter duration means less sensitivity to interest
rate risk, and vice versa). However, our longer relative duration was a
positive in the final quarter of the period as yields began to move lower.

In terms of specific fixed income sectors, we maintained a neutral-to-slightly
underweight position in corporate bonds and mortgages for much of the year, a
strategy that benefited performance compared to the benchmark. This was
particularly true in the second quarter of 2006 as credit spreads (versus
Treasury issues of comparable maturity) widened. Conversely, we overweighted
structured products, such as asset-backed securities (ABS) and commercial
mortgage-backed securities (CMBS), a move that enhanced performance as these
sectors offered an incremental yield advantage over Treasury issues. Exposure
to Treasury Inflation Protected Securities (TIPS) early in the year detracted
from performance.


What changes were made to the portfolio during the period?

We actively adjusted the portfolio's duration profile based on our assessment
of interest rate direction. Although interest rates rose year-over-year, they
also fell at times when the Fed began to soften its stance on inflation and
expectations for future interest rate hikes declined. As Chairman Bernanke
sought to establish credibility with the markets, his statements often
resulted in ambiguity regarding the direction of interest rates. We worked to
manage the Fund's duration amid the uncertainty.

We began the year with a relatively short duration. In March, the Treasury
curve steepened by 20 basis points (.20%) between the two-year and 30-year
sectors. This was a dramatic one-month move considering the flatness of the
curve, and served to support the short end as the long end normalized. This
prompted us to remove some of our curve flattening bias and to move from a
short duration bias toward a more neutral duration profile. By the second
quarter of 2006, as long-term interest rates continued to rise, the Fund's
duration was slightly longer than that of the benchmark index. In our view,
the 10-year U.S. Treasury began to represent value as its yield approached
5.25%. By period-end, as long-term interest rates moved lower, we returned to
a slightly short duration bias in an effort to shield the portfolio from any
potential backup in rates.



BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



Turning to sectors, the portfolio was underweight in corporate bonds for much
of the year as credit spreads remained tight, meaning there was little
additional yield to be gained in exchange for the risk involved. In the final
three months of the period, we reestablished some exposure to corporate bonds
as spreads widened and value was restored to the sector. We felt corporate
bonds should perform well if rates remained at or near the low levels reached
in the second quarter. With this additional exposure, the portfolio's position
in corporate bonds increased from an underweight versus the benchmark to an
overweight. At period-end, 23.6% of the Fund's net assets was invested in
investment grade corporate bonds.

For the most part, we continued to favor high-quality spread sectors
throughout the year for their yield-enhancement potential. Having said that,
we did reduce exposure to these sectors in the second quarter of 2006 in
keeping with a general theme of risk reduction in the portfolio. Overall, we
preferred CMBS and ABS for their relatively high credit quality and potential
to generate additional yield for the portfolio.


How would you characterize the Fund's position at the close of the period?

In our last report to shareholders, we noted that a slowdown in economic
activity should help to calm some of the inflationary fears propagated by the
Fed. This seemed to materialize as the Fed opted to interrupt its two-year
interest rate-hiking campaign in August, and again chose to leave rates
unchanged on September 20, citing an obvious slowdown in the economy as a
factor in its decision. Indeed, inflation is a lagging indicator, and we
believe we have yet to feel the full effects of the Fed's 17 consecutive
interest rate hikes. In addition, the housing market is weakening and high
energy prices have taken a bite out of consumption. All of this gives us
reason for optimism. As such, we shifted the portfolio slightly to take
advantage of a more favorable credit environment.

* Class A Shares incur a maximum initial sales charge (front-end load) of 4%
and an account maintenance fee of 0.25% per year (but no distribution fee).

* Class B Shares are subject to a maximum contingent deferred sales charge of
4%, declining to 0% after six years. All Class B Shares purchased prior to
December 1, 2002 will maintain the four-year schedule. In addition, Class B
Shares are subject to a distribution fee of 0.50% per year and an account
maintenance fee of 0.25% per year. These shares automatically convert to Class
A Shares after approximately 10 years. (There is no initial sales charge for
automatic share conversions.)

*Class C Shares are subject to a distribution fee of 0.55% per year and an
account maintenance fee of 0.25% per year. In addition, Class C Shares are
subject to a 1% contingent deferred sales charge if redeemed within one year
of purchase.

* Class I Shares are not subject to any front-end sales charge. Class I Shares
bear no ongoing distribution or account maintenance fees and are available
only to eligible investors.

* Class R Shares do not incur a maximum sales charge (front-end load) or
deferred sales charge. These shares are subject to a distribution fee of 0.25%
per year and an account maintenance fee of 0.25% per year. Class R Shares are
available only to certain retirement plans. Prior to inception, Class R Share
performance results are those of the Class I Shares (which have no
distribution or account maintenance fees) restated for Class R Share fees.

None of the past results shown should be considered a representation of future
performance. Current performance may be lower or higher than the performance
data quoted. Refer to www.blackrock.com to obtain performance data current to
the most recent month-end. Performance results do not reflect the deduction of
taxes that a shareholder would pay on fund distributions or the redemption of
fund shares. Figures shown in each of the following tables assume reinvestment
of all dividends and capital gain distributions, if any, at net asset value on
the payable date. Investment return and principal value of shares will
fluctuate so that shares, when redeemed, may be worth more or less than their
original cost. Dividends paid to each class of shares will vary because of the
different levels of account maintenance, distribution and transfer agency fees
applicable to each class, which are deducted from the income available to be
paid to shareholders. The Portfolio's Investment Adviser waived a portion of
its fee. Without such waiver, the Portfolio's performance would have been
lower.

Disclosure of Expenses


Shareholders of this Fund may incur the following charges: (a) expenses
related to transactions, including sales charges, redemption fees and exchange
fees; and (b) operating expenses including advisory fees, distribution fees
including 12b-1 fees, and other Fund expenses. The following example (which is
based on a hypothetical investment of $1,000 invested on April 1, 2006 and
held through September 30, 2006) is intended to assist shareholders both in
calculating expenses based on an investment in the Fund and in comparing these
expenses with similar costs of investing in other mutual funds.

The first table below provides information about actual account values and
actual expenses. In order to estimate the expenses a shareholder paid during
the period covered by this report, shareholders can divide their account value
by $1,000 and then multiply the result by the number in the first line under
the heading entitled "Expenses Paid During the Period."

The second table below provides information about hypothetical account values
and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses. In order to assist
shareholders in comparing the ongoing expenses of investing in this Fund and
other funds, compare the 5% hypothetical example with the 5% hypothetical
examples that appear in other funds' shareholder reports.

The expenses shown in the table are intended to highlight shareholders'
ongoing costs only and do not reflect any transactional expenses, such as
sales charges, redemption fees or exchange fees. Therefore, the second table
is useful in comparing ongoing expenses only, and will not help shareholders
determine the relative total expenses of owning different funds. If these
transactional expenses were included, shareholder expenses would have been
higher.

 * For each class of the Fund, expenses are equal to the annualized expense ratio for the class
   (.84% for Class A, 1.36% for Class B, 1.42% for Class C, .59% for Class I and 1.09% for Class R),
   multiplied by the average account value over the period, multiplied by 182/365 (to reflect the
   one-half year period shown). Because the Fund is a feeder fund, the expense table example
   reflects the expenses of both the feeder fund and the master fund in which it invests.

** Hypothetical 5% annual return before expenses is calculated by pro-rating the number of days in
   the most recent fiscal half year divided by 365.

BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



Notes to Financial Statements                               BlackRock Bond Fund


1. Significant Accounting Policies:
On September 29, 2006, Core Bond Portfolio (the "ML Fund") and Merrill Lynch
Bond Fund, Inc., which the ML Fund is a part of, were renamed BlackRock Bond
Fund (the "Fund") and BlackRock Bond Fund, Inc. (the "Bond Fund"),
respectively. The Bond Fund is registered under the Investment Company Act of
1940, as amended, as a diversified, open-end management investment company.
The Fund seeks to achieve its investment objective by investing all of its
assets in Master Core Bond Portfolio which was renamed on September 29, 2006,
Master Bond Portfolio (the "Master Portfolio"), of Master Bond Trust, a mutual
fund that has the same investment objective and strategies as the Fund. The
value of the Fund's investment in the Master Portfolio reflects the Fund's
proportionate interest in the net assets of the Master Portfolio. The
performance of the Fund is directly affected by the performance of the Master
Portfolio. The financial statements of the Master Portfolio, including the
Schedule of Investments, are included elsewhere in this report and should be
read in conjunction with the Fund's financial statements. The Fund's financial
statements are prepared in conformity with U.S. generally accepted accounting
principles, which may require the use of management accruals and estimates.
Actual results may differ from these estimates. The percentage of the Master
Portfolio owned by the Fund at September 30, 2006 was 70.3%. The Fund offers
multiple classes of shares. Class A Shares are sold with a front-end sales
charge. Shares of Class B and Class C may be subject to a contingent deferred
sales charge. Class I Shares are sold only to certain eligible investors.
Class R Shares are sold only to certain retirement plans. All classes of
shares have identical voting, dividend, liquidation and other rights and the
same terms and conditions, except that Class A, Class B, Class C and Class R
Shares bear certain expenses related to the account maintenance of such
shares, and Class B, Class C and Class R Shares also bear certain expenses
related to the distribution of such shares. Each class has exclusive voting
rights with respect to matters relating to its account maintenance and
distribution expenditures (except that Class B shareholders may vote on
certain changes to the Class A distribution plan). Effective October 2, 2006,
Class A, Class B, Class C and Class I Shares were redesignated Investor A,
Investor B, Investor C1 and Institutional Shares, respectively. Class R Shares
were not redesignated. Income, expenses (other than expenses attributable to a
specific class) and realized and unrealized gains and losses are allocated
daily to each class based on its relative net assets. The following is a
summary of significant accounting policies followed by the Fund.

(a) Valuation of investments--The Fund records its investment in the Master
Portfolio at fair value. Valuation of securities held by the Master Portfolio
is discussed in Note 1(a) of the Master Portfolio's Notes to Financial
Statements, which is included elsewhere in this report.

(b) Investment income and expenses--The Fund records daily its proportionate
share of the Master Portfolio's income, expenses and realized and unrealized
gains and losses. In addition, the Fund accrues its own expenses.

(c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no federal income tax provision is required.

(d) Recent accounting pronouncement--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48") entitled
"Accounting for Uncertainty in Income Taxes--an interpretation of FASB
Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax
position must meet in connection with accounting for uncertainties in income
tax positions taken or expected to be taken by an entity including mutual
funds before being measured and recognized in the financial statements.
Adoption of FIN 48 is required for fiscal years beginning after December 15,
2006. The impact on the Fund's financial statements, if any, is currently
being assessed.

(e) Prepaid registration fees--Prepaid registration fees are charged to
expense as the related shares are issued.

(f) Dividends and distributions--Dividends from net investment income are
declared daily and paid monthly. Distributions of capital gains are recorded
on the ex-dividend dates.

(g) Investment transactions--Investment transactions in the Master Portfolio
are accounted for on a trade date basis.

(h) Expenses--Certain expenses have been allocated to the individual funds in
the Bond Fund on a pro rata basis based upon the respective aggregate net
asset value of each fund included in the Bond Fund.

Notes to Financial Statements (continued)                   BlackRock Bond Fund


(i) Reclassification--U.S. generally accepted accounting principles require
that certain components of net assets be adjusted to reflect permanent
differences between financial and tax reporting. Accordingly, during the
current year, $3,832,331 has been reclassified between accumulated
distributions in excess of net investment income and accumulated net realized
capital losses allocated from the Master Portfolio as a result of permanent
differences attributable to accounting for swap agreements, accounting for
principal paydowns, foreign currency transactions and amortization methods on
fixed income securities. This reclassification has no effect on net assets or
net asset values per share.


2. Transactions with Affiliates:
The Bond Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton
Services, Inc. ("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch
& Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for
the management of the Funds and provides the necessary personnel, facilities,
equipment and certain other services necessary to the operations of the Bond
Fund. For such services, FAM receives, at the end of each month, a fee with
respect to each Fund at the annual rates set forth below which are based upon
the aggregate average daily value of the Bond Fund's net assets at the
following annual rates: .50% of the Bond Fund's average daily net assets
not exceeding $250 million; .45% of the average daily net assets in excess of
$250 million but not exceeding $500 million; .40% of average daily net assets
in excess of $500 million but not exceeding $750 million; and .35% of average
daily net assets in excess of $750 million. For the year ended September 30,
2006, the aggregate average daily net assets of the Bond Fund, including the
Bond Fund's BlackRock High Income Fund (formerly High Income Portfolio of
Merrill Lynch Bond Fund, Inc.) and BlackRock Intermediate Term Fund (formerly
Intermediate Bond Fund of Merrill Lynch Bond Fund, Inc.) was approximately
$3,794,317,000.

FAM has contractually agreed to waive the Fund's investment advisory fee in
the amount of the Fund's share of the investment advisory fee paid by the
Master Portfolio. For the year ended September 30, 2006, FAM earned fees of
$7,170,155 of which $1,283,411 were waived. FAM has entered into a Sub-
Advisory Agreement with Merrill Lynch Asset Management U.K. Limited ("MLAM
U.K."), an affiliate of FAM, pursuant to which MLAM U.K. provides investment
advisory services to FAM with respect to the Bond Fund. There is no increase
in the aggregate fees paid by the Bond Fund for these services.

The Bond Fund has also entered into a Distribution Agreement and Distribution
Plan with FAM Distributors, Inc. ("FAMD" or the "Distributor"), a wholly owned
subsidiary of Merrill Lynch Group, Inc. Pursuant to the Distribution Plan
adopted by the Bond Fund in accordance with Rule 12b-1 under the Investment
Company Act of 1940, the Fund pays the Distributor ongoing account maintenance
and distribution fees. The fees are accrued daily and paid monthly at annual
rates based upon the average daily net assets of the shares as follows:


                                            Account
                                         Maintenance       Distribution
                                                 Fee                Fee

Class A                                         .25%                 --
Class B                                         .25%               .50%
Class C                                         .25%               .55%
Class R                                         .25%               .25%


Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, also provides
account maintenance and distribution services to the Bond Fund. The ongoing
account maintenance fee compensates the Distributor and MLPF&S for providing
account maintenance services to Class A, Class B, Class C and Class R
shareholders. The ongoing distribution fee compensates the Distributor and
MLPF&S for providing shareholder and distribution-related services to Class B,
Class C and Class R shareholders.

For the year ended September 30, 2006, FAMD earned underwriting discounts and
direct commissions and MLPF&S earned dealer concessions on sales of the Fund's
Class A and Class I Shares as follows:


                                                FAMD             MLPF&S

Class A                                    $  90,953         $  855,400
Class I                                    $  20,247         $  123,393


For the year ended September 30, 2006, MLPF&S received contingent deferred
sales charges of $191,479 and $84,238 relating to transactions in Class B and
Class C Shares, respectively. Furthermore, MLPF&S received contingent deferred
sales charges of $305 relating to transactions subject to front-end sales
charge waivers in Class A Shares.

Financial Data Services, Inc. ("FDS"), a wholly owned subsidiary of ML & Co.,
is the Fund's transfer agent.

In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to
contribute ML & Co.'s investment management business, including FAM, to the
investment management business of BlackRock, Inc. The transaction closed on
September 29, 2006.

On August 15, 2006, shareholders of the Fund approved a new Investment
Advisory Agreement for the Bond Fund and the Master Portfolio, with BlackRock
Advisors, Inc. (the "Manager"), a wholly owned subsidiary of BlackRock, Inc.
BlackRock Advisors, Inc. was reorganized into BlackRock Advisors, LLC. The new
advisory agreement became effective on September 29, 2006 and the investment
advisory fee is unchanged.

In connection with the closing, the Fund's Transfer Agent became PFPC, Inc.,
an affiliate of the Manager. In addition, BlackRock Distributors, Inc., an
affiliate of BlackRock, Inc., became an additional distributor.

Prior to the closing, certain officers and/or directors of the Bond Fund are

Commencing September 29, 2006, certain officers and/or directors of the Bond
Fund are officers and/or directors of BlackRock, Inc. or its affiliates.

4. Distributions to Shareholders:
The tax character of distributions paid during the fiscal years ended
September 30, 2006 and September 30, 2005 was as follows:


                                           9/30/2006          9/30/2005

Distributions paid from:

                                     ===============    ===============


As of September 30, 2006, the components of accumulated losses on a
tax basis were as follows:


Accumulated distributions in excess of
   investment income--net                               $     (698,268)

Unrealized gains--net                                    (22,402,566)**
                                                        ---------------

                                                        ===============

 * On September 30, 2006, the Fund had a net capital loss carry-
   forward of $15,296,383, of which $2,086,933 expires in 2007,
   $392,843 expires in 2008 and $12,816,607 expires in 2009.
   This amount will be available to offset like amounts of any future
   taxable gains.

** The difference between book-basis and tax-basis net unrealized
   losses is attributable primarily to the tax deferral of losses on wash
   sales, the tax deferral of losses on straddles, the realization for
   tax purposes of unrealized gains (losses) on certain futures and
   forward foreign currency contracts, the difference between book
   and tax amortization methods for premiums and discounts on fixed
   income securities, the realization for tax purposes of unrealized
   gains on investments in passive foreign investment companies, the
   deferral of post-October capital losses for tax purposes and other
   book/tax temporary differences.

Fund, Inc.:
On October 16, 2006, the Fund acquired all of the net assets of BlackRock

BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



Report of Independent Registered Public Accounting Firm     BlackRock Bond Fund


To the Shareholders and Board of Directors of
BlackRock Bond Fund, Inc.:

We have audited the accompanying statement of assets and liabilities of
BlackRock Bond Fund, one of the portfolios constituting BlackRock Bond Fund,
Inc. (the "Fund"), formerly Core Bond Portfolio of Merrill Lynch Bond Fund,
Inc., as of September 30, 2006 and the related statement of operations for the
year then ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the 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, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
BlackRock Bond Fund of BlackRock Bond Fund, Inc. as of September 30, 2006, the
results of its operations for the year then ended, the changes in its net
assets for each of the two years in the period then ended, and its financial
highlights for each of the five years in the period then ended, in conformity
with U.S. generally accepted accounting principles.

Notes to Financial Statements                             Master Bond Portfolio


1. Significant Accounting Policies:
On September 29, 2006, Master Core Bond Portfolio was renamed Master Bond
Portfolio (the "Master Portfolio"), which is part of Master Bond Trust (the
"Trust"). The Master Portfolio is registered under the Investment Company Act
of 1940, as amended, and is organized as a Delaware statutory trust. The
Declaration of Trust permits the Trustees to issue nontransferable interests
in the Master Portfolio, subject to certain limitations. The Master
Portfolio's financial statements are prepared in conformity with U.S.
generally accepted accounting principles, which may require the use of
management accruals and estimates. Actual results may differ from these
estimates. The following is a summary of significant accounting policies
followed by the Master Portfolio.

(a) Valuation of investments--Debt securities are traded primarily in the over-
the-counter ("OTC") markets and are valued at the last available bid price in
the OTC market or on the basis of values obtained by a pricing service.
Pricing services use valuation matrixes that incorporate both dealer-supplied
valuations and valuation models. The procedures of the pricing service and its
valuations are reviewed by the officers of the Trust under the general
direction of the Board of Trustees. Such valuations and procedures will be
reviewed periodically by the Board of Trustees of the Trust. Financial futures
contracts and options thereon, which are traded on exchanges, are valued at
their closing prices as of the close of such exchanges. Options written or
purchased are valued at the last sale price in the case of exchange-traded
options. In the case of options traded in the OTC market, valuation is the
last asked price (options written) or the last bid price (options purchased).
Swap agreements are valued based upon quoted fair valuations received daily by
the Master Portfolio from a pricing service or counterparty. Short-term
investments with a remaining maturity of 60 days or less are valued at
amortized cost, which approximates market value, under which method the
investment is valued at cost and any premium or discount is amortized on a
straight line basis to maturity. Valuation of other short-term investment
vehicles is generally based on the net asset value of the underlying
investment vehicle or amortized cost. Repurchase agreements are valued at
cost plus accrued interest. Investments in open-end investment companies are
valued at their net asset value each business day. Securities and other assets
for which market quotations are not readily available are valued at fair value
as determined in good faith by or under the direction of the Board of Trustees
of the Trust.

Equity securities that are held by the Master Portfolio, which are traded on
stock exchanges or the Nasdaq National Market, are valued at the last sale
price or official close price on the exchange, as of the close of business on
the day the securities are being valued or, lacking any sales, at the last
available bid price for long positions, and at the last available asked price
for short positions. In cases where equity securities are traded on more than
one exchange, the securities are valued on the exchange designated as the
primary market by or under the authority of the Board of Trustees of the
Trust. Long positions traded in the OTC market, Nasdaq Small Cap or Bulletin
Board are valued at the last available bid price obtained from one or more
dealers or pricing services approved by the Board of Trustees of the Trust.
Short positions traded in the OTC market are valued at the last available
asked price. Portfolio securities that are traded both in the OTC market and
on a stock exchange are valued according to the broadest and most
representative market.

Generally, trading in foreign securities is substantially completed each day
at various times prior to the close of business on the New York Stock Exchange
("NYSE"). The values of such securities used in computing the net assets of
the Master Portfolio are determined as of such times. Foreign currency
exchange rates also are generally determined prior to the close of business on
the NYSE. As of October 2, 2006, foreign currency exchange rates will be
determined as of the close of business on the NYSE. Occasionally, events
affecting the values of such securities and such exchange rates may occur
between the times at which they are determined and the close of business on
the NYSE that may not be reflected in the computation of the Master Portfolio's
net assets. If events (for example, a company announcement, market volatility
or a natural disaster) occur during such periods that are expected to
materially affect the value of such securities, those securities may be valued
at their fair value as determined in good faith by the Trust's Board of
Trustees or by the Investment Adviser using a pricing service and/or
procedures approved by the Trust's Board of Trustees.

Notes to Financial Statements (continued)                 Master Bond Portfolio


(b) Derivative financial instruments--The Master Portfolio may engage in
various portfolio investment strategies both to increase the return of the
Master Portfolio and to hedge, or protect its exposure to interest rate
movements and movements in the securities markets. Losses may arise due to
changes in the value of the contract or if the counterparty does not perform
under the contract.

* Financial futures contracts--The Master Portfolio may purchase or sell
financial futures contracts and options on such financial futures contracts.
Financial futures contracts are contracts for delayed delivery of securities
at a specific future date and at a specific price or yield. Upon entering into
a contract, the Master Portfolio deposits and maintains as collateral such
initial margin as required by the exchange on which the transaction is
effected. Pursuant to the contract, the Master Portfolio agrees to receive
from or pay to the broker an amount of cash equal to the daily fluctuation in
value of the contract. Such receipts or payments are known as variation margin
and are recorded by the Master Portfolio as unrealized gains or losses. When
the contract is closed, the Master Portfolio records a realized gain or loss
equal to the difference between the value of the contract at the time it was
opened and the value at the time it was closed.

* Options--The Master Portfolio may purchase and write call and put options.
When the Master Portfolio writes an option, an amount equal to the premium
received by the Master Portfolio is reflected as an asset and an equivalent
liability. The amount of the liability is subsequently marked-to-market to
reflect the current market value of the option written. When a security is
purchased or sold through an exercise of an option, the related premium paid
(or received) is added to (or deducted from) the basis of the security
acquired or deducted from (or added to) the proceeds of the security sold.
When an option expires (or the Master Portfolio enters into a closing
transaction), the Master Portfolio realizes a gain or loss on the option to
the extent of the premiums received or paid (or a gain or loss to the extent
that the cost of the closing transaction exceeds the premium paid or
received).

Written and purchased options are non-income producing investments.

* Forward foreign exchange contracts--The Master Portfolio may enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. The contract is marked-to-market daily
and the change in market value is recorded by the Master Portfolio as an
unrealized gain or loss. When the contract is closed, the Master Portfolio
records a realized gain or loss equal to the difference between the value at
the time it was opened and the value at the time it was closed.

* Foreign currency options and futures--The Master Portfolio may also purchase
or sell listed or OTC foreign currency options, foreign currency futures and
related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be
effected with respect to hedges on non-U.S. dollar-denominated securities
owned by the Master Portfolio, sold by the Master Portfolio but not yet
delivered, or committed or anticipated to be purchased by the Master
Portfolio.

* Swaps--The Master Portfolio may enter into swap agreements, which are OTC
contracts in which the Master Portfolio and a counterparty agree to make
periodic net payments on a specified notional amount. The net payments can be
made for a set period of time or may be triggered by a predetermined credit
event. The net periodic payments may be based on a fixed or variable interest
rate; the change in market value of a specified security, basket of securities,
or index; or the return generated by a security. These periodic payments
received or made by the Master Portfolio are recorded in the accompanying
Statement of Operations as realized gains or losses, respectively. Gains or
losses are also realized upon termination of the swap agreements. Swaps are
marked-to-market daily and changes in value are recorded as unrealized
appreciation (depreciation). Risks include changes in the returns of the
underlying instruments, failure of the counterparties to perform under the
contracts' terms and the possible lack of liquidity with respect to the
swap agreements.

Notes to Financial Statements (continued)                 Master Bond Portfolio


(c) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized.
Assets and liabilities denominated in foreign currencies are valued at the
exchange rate at the end of the period. Foreign currency transactions are the
result of settling (realized) or valuing (unrealized) assets or liabilities
expressed in foreign currencies into U.S. dollars. Realized and unrealized
gains or losses from investments include the effects of foreign exchange rates
on investments. The Master Portfolio invests in foreign securities, which may
involve a number of risk factors and special considerations not present with
investments in securities of U.S. corporations.

(d) Income taxes--The Master Portfolio is classified as a partnership for
federal income tax purposes. As such, each investor in the Master Portfolio is
treated as owner of its proportionate share of the net assets, income,
expenses and realized and unrealized gains and losses of the Master Portfolio.
Therefore, no federal income tax provision is required. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates. It is intended that the Master Portfolio's
assets will be managed so an investor in the Master Portfolio can satisfy the
requirements of Subchapter M of the Internal Revenue Code.

(e) Recent accounting pronouncement--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48") entitled
"Accounting for Uncertainty in Income Taxes--an interpretation of FASB
Statement No. 109." FIN 48 prescribes the minimum recognition threshold a tax
position must meet in connection with accounting for uncertainties in income
tax positions taken or expected to be taken by an entity including mutual
funds before being measured and recognized in the financial statements.
Adoption of FIN 48 is required for fiscal years beginning after December 15,
2006. The impact on the Master Portfolio's financial statements, if any, is
currently being assessed.

(f) Security transactions and investment income--Security transactions are
accounted for on the date the securities are purchased or sold (the trade
dates). Realized gains and losses on security transactions are determined on
the identified cost basis. Dividend income is recorded on the ex-dividend
dates. Dividends from foreign securities where the ex-dividend date may have
passed are subsequently recorded when the Master Portfolio has determined the
ex-dividend date. Interest income is recognized on the accrual basis.

(g) Securities lending--The Master Portfolio may lend securities to financial
institutions that provide cash or securities issued or guaranteed by the U.S.
government as collateral, which will be maintained at all times in an amount
equal to at least 100% of the current market value of the loaned securities.
The market value of the loaned securities is determined at the close of
business of the Master Portfolio and any additional required collateral is
delivered to the Master Portfolio on the next business day. Where the Master
Portfolio receives securities as collateral for the loaned securities, it
collects a fee from the borrower. The Master Portfolio typically receives the
income on the loaned securities but does not receive the income on the
collateral. Where the Master Portfolio receives cash collateral, it may invest
such collateral and retain the amount earned on such investment, net of any
amount rebated to the borrower. Loans of securities are terminable at any time
and the borrower, after notice, is required to return borrowed securities
within five business days. The Master Portfolio may pay reasonable finder's,
lending agent, administrative and custodial fees in connection with its loans.
In the event that the borrower defaults on its obligation to return borrowed
securities because of insolvency or for any other reason, the Master Portfolio
could experience delays and costs in gaining access to the collateral. The
Master Portfolio also could suffer a loss where the value of the collateral
falls below the market value of the borrowed securities, in the event of
borrower default or in the event of losses on investments made with cash
collateral.

(h) Short sales--When the Master Portfolio engages in a short sale, 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 maintains a segregated account of securities as collateral for the
short sales. The Master Portfolio is exposed to market risk based on the
amount, if any, that the market value of the security exceeds the market value
of the securities in the segregated account. The Master Portfolio is required
to repay the counterparty any dividends or interest received on the security
sold short.

2. Investment Advisory Agreement and Transactions with Affiliates:
The Trust, on behalf of the Master Portfolio, has entered into an Investment
Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general
partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly owned
subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited
partner.

FAM is responsible for the management of the Master Portfolio's investments
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Master Portfolio. For such
services, the Master Portfolio pays a monthly fee with respect to the Master
Portfolio based upon the aggregate average daily value of the Master
Portfolio's net assets and BlackRock Bond Fund, Inc. (the "Fund") (formerly
Merrill Lynch Bond Fund, Inc.), BlackRock High Income and BlackRock
Intermediate Term Funds' (formerly High Income and Intermediate Portfolios,
respectively) net assets at an annual rate of .20% of the average daily net
assets not exceeding $250 million; .15% of average daily net assets in excess
of $250 million but less than $500 million; .10% of average daily net assets
in excess of $500 million but less than $750 million and .05% in excess of
$750 million. For the year ended September 30, 2006, the aggregate average
daily net assets of the Master Portfolio, including the Fund's High Income
Fund and Intermediate Term Fund, was approximately $4,670,883,000. FAM has
entered into a Sub-Advisory Agreement with Merrill Lynch Asset Management U.K.
Limited ("MLAM U.K."), an affiliate of FAM, pursuant to which MLAM U.K.
provides investment advisory services to MLIM with respect to the Master
Portfolio. There is no increase in the aggregate fees paid by the Master
Portfolio for these services.

The Master Portfolio has received an exemptive order from the Securities and
Exchange Commission permitting it to lend portfolio securities to Merrill
Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, or
its affiliates. As of September 30, 2006, the Master Portfolio lent securities
with a value of $91,721,300 to MLPF&S or its affiliates. Pursuant to that
order, the Master Portfolio also has retained Merrill Lynch Investment
Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending
agent for a fee based on a share of the returns on investment of cash
collateral. MLIM, LLC may, on behalf of the Master Portfolio, invest cash
collateral received by the Trust for such loans, among other things, in a
private investment company managed by MLIM, LLC or in registered money market
funds advised by Merrill Lynch Investment Managers, L.P. ("MLIM"), an
affiliate of FAM. For the year ended September 30, 2006, MLIM, LLC received
$317,937 in securities lending agent fees.

In addition, MLPF&S received $489 in commissions on the execution of portfolio
security transactions for the Master Portfolio for the year ended September
30, 2006.

For the year ended September 30, 2006, the Master Portfolio reimbursed FAM
$64,595 for certain accounting services.

In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to
contribute ML & Co.'s investment management business, including FAM, to the
investment management business of BlackRock, Inc. The transaction closed on
September 29, 2006.

On August 15, 2006, the shareholders of the investors of the Master Portfolio
approved a new Investment Advisory Agreement with BlackRock Advisors, Inc.,
(the "Manager") a wholly owned subsidiary of BlackRock, Inc. BlackRock
Advisors, Inc. was reorganized into BlackRock Advisors, LLC. The new advisory
agreement became effective on September 29, 2006 and the investment advisory
fee is unchanged. In addition, the Manager has entered into a sub-advisory
agreement with BlackRock Financial Management, Inc., an affiliate, under which
the Manager pays the Sub-Adviser for services it provides a fee equal to 59%
of the management fee paid to the Manager.

In connection with the closing, MLIM, LLC, the security lending agent, will
become BlackRock Investment Managers, LLC.

Prior to the closing, certain officers and/or trustees of the Trust are
officers and/or directors of FAM, PSI, MLAM U.K., ML & Co., MLIM, and/or MLIM,
LLC.

Commencing September 29, 2006, certain officers and/or trustees of the Trust
are officers and/or directors of BlackRock, Inc. or its affiliates.

securities, for the year ended September 30, 2006 were $5,381,237,325 and

Report of Independent Registered Public Accounting Firm   Master Bond Portfolio


To the Investors and Board of Trustees of
Master Bond Trust:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of Master Bond Portfolio, formerly
Master Core Bond Portfolio, of Master Bond Trust (the "Trust") as of September
30, 2006 and the related statement of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period
then ended and the financial highlights for the respective periods then ended.
These financial statements and financial highlights are the responsibility of
the Trust'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 Trust 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
Trust'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, 2006
by correspondence with the custodian and brokers; where replies were not
received, we performed other auditing procedures. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Master Bond Portfolio of Master Bond Trust as of September 30, 2006, the
results of its operations for the year then ended, the changes in its net
assets for each of the two years in the period then ended, and its financial
highlights for the respective periods then ended, in conformity with U.S.
generally accepted accounting principles.

Disclosure of New Investment Advisory Agreement


New BlackRock Investment Advisory Agreement--Matters Considered by the Boards

BlackRock Bond Fund (the "Fund") of BlackRock Bond Fund, Inc. is a "feeder"
fund that invests all its assets in Master Bond Portfolio of Master Bond Trust
(the "Trust"), which has the same investment objectives and strategies as the
Fund. All investments are made at the Trust level.

In connection with the combination of Merrill Lynch's investment advisory
business, including Fund Asset Management, L.P. (the "Previous Investment
Adviser"), with that of BlackRock, Inc. ("BlackRock") to create a new
independent company ("New BlackRock") (the "Transaction"), the Board of
Trustees of the Trust considered and approved a new investment advisory
agreement between the Master Bond Trust, on behalf of the Master Bond
Portfolio, and BlackRock Advisors, LLC ("BlackRock Advisors"). The Fund's
shareholders subsequently approved the Trust's BlackRock investment advisory
agreement and it became effective on September 29, 2006, replacing the
investment advisory agreement with the Previous Investment Adviser.

In addition, in connection with the Transaction, the Board of Directors of the
Fund considered and approved a new investment advisory agreement between
BlackRock Bond Fund, Inc., on behalf of the Fund, and BlackRock Advisors
(together with the new advisory agreement for the Trust, the "BlackRock
Investment Advisory Agreements"). The Fund's shareholders subsequently
approved the Fund's BlackRock Investment Advisory Agreement and it became
effective on September 29, 2006, replacing the investment advisory agreement
with the Previous Investment Adviser (together with the Trust's investment
advisory agreement with the Previous Investment Adviser, the "Previous
Investment Advisory Agreements").

Each Board discussed the respective BlackRock Investment Advisory Agreement at
telephonic and in-person meetings held during April and May 2006. Each Board,
including the independent directors/trustees, approved the respective
BlackRock Investment Advisory Agreement at an in-person meeting held on May
12, 2006. The Fund's Board also approved the issuance of new classes of shares
and new distribution arrangements with respect to these new share classes,
including higher distribution fees for certain new share classes, to take
effect after the closing of the Transaction. The Fund's Board also approved
revised front-end sales charge schedules with respect to certain classes of
shares of the Fund.

To assist each Board in its consideration of the respective BlackRock
Investment Advisory Agreement, BlackRock provided materials and information
about BlackRock, including its financial condition and asset management
capabilities and organization, and Merrill Lynch provided materials and
information about the Transaction. The independent directors/trustees, through
their independent legal counsel, also requested and received additional
information from Merrill Lynch and BlackRock in connection with their
consideration of the respective BlackRock Investment Advisory Agreement. The
additional information was provided in advance of the May 12, 2006 meetings.
In addition, the independent directors consulted with their counsel and
counsel for the Fund and the Trust on numerous occasions, discussing, among
other things, the legal standards and certain other considerations relevant to
each Board's deliberations.

At each Board meeting, the directors/trustees discussed with Merrill Lynch
management and certain BlackRock representatives the Transaction, its
strategic rationale and BlackRock's general plans and intentions regarding the
Fund and the Trust. At these Board meetings, representatives of Merrill Lynch
and BlackRock made presentations to and responded to questions from each
Board. Each Board also inquired about the plans for and anticipated roles and
responsibilities of certain employees and officers of the Previous Investment
Adviser, and of its affiliates, to be transferred to BlackRock in connection
with the Transaction. The independent directors/trustees also conferred
separately and with their counsel about the Transaction, including a proposed
reorganization in which the Fund would acquire the assets and the liabilities
of the BlackRock Intermediate Term Portfolio of BlackRock Bond Fund, Inc., and
other matters related to the Transaction on a number of occasions, including
in connection with the April and May 2006 meetings. After the presentations
and after reviewing the written materials provided, the independent directors/
trustees met in executive sessions with their counsel to consider the BlackRock
Investment Advisory Agreements.

In connection with each Board's review of the respective BlackRock Investment
Advisory Agreement, Merrill Lynch and/or BlackRock advised the Boards about a
variety of matters. The advice included the following, among other matters:

* that there was not expected to be any diminution in the nature, quality and
  extent of services provided to the Fund and the Trust and their shareholders
  by BlackRock Advisors, including compliance services;



BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



* that operation of New BlackRock as an independent investment management
  firm would enhance its ability to attract and retain talented professionals;

* that the Fund and the Trust were expected to benefit from having access to
  BlackRock's state of the art technology and risk management analytic tools,
  including investment tools, provided under the BlackRock Solutions (R) brand
  name;

* that BlackRock had no present intention to alter any applicable expense
  waivers or reimbursements that were currently in effect and, while it
  reserved the right to do so in the future, it would seek the approval of
  each Board before making any changes;

* that BlackRock and Merrill Lynch would enter into an agreement, for an
  initial three-year period and automatically renewable from year to year
  thereafter, in connection with the Transaction under which Merrill Lynch-
  affiliated broker-dealers would continue to offer the Fund as an investment
  product;

* that BlackRock Advisors would have substantially the same access to the
  Merrill Lynch sales force when distributing shares of the Fund as was
  currently being provided to the Previous Investment Adviser and that other
  arrangements between the Previous Investment Adviser and Merrill Lynch
  sales channels would be preserved;

* that the Fund would have access to BlackRock's network of third party
  brokers, retirement plan platforms and registered investment advisers;

* that in connection with the Transaction, Merrill Lynch and BlackRock had
  agreed to conduct, and use reasonable best efforts to cause their
  respective affiliates to conduct, their respective businesses in compliance
  with the conditions of Section 15(f) of the Investment Company Act of 1940
  (the "1940 Act") in relation to any public funds advised by BlackRock or
  the Previous Investment Adviser (or affiliates), respectively; and

* that, Merrill Lynch and BlackRock would derive benefits from the
  Transaction and that, as a result, they had a financial interest in the
  matters being considered that was different from that of Fund or Trust
  shareholders.

Each Board considered the information provided by Merrill Lynch and BlackRock
above, and, among other factors, the following:

* the potential benefits to Fund and Trust shareholders from being part of a
  combined fund family with BlackRock-sponsored funds, including possible
  economies of scale and access to investment opportunities;

* the potential for expanding distribution of Fund shares through improved
  access to third party distribution;

* the reputation, financial strength and resources of BlackRock and its
  investment advisory subsidiaries and the anticipated financial strength and
  resources of New BlackRock;

* the compliance policies and procedures of BlackRock Advisors;

* the terms and conditions of the BlackRock Investment Advisory Agreements,
  including the fact that the schedule of the Fund's/Trust's total advisory
  fees would not increase under the BlackRock Investment Advisory Agreements,
  but would remain the same;

* that in February 2006, each Board had performed a full annual review of
  each respective Previous Investment Advisory Agreement, as required by the
  1940 Act, and had determined that the Previous Investment Adviser had the
  capabilities, resources and personnel necessary to provide the advisory and
  administrative services that were then being provided to the Fund/Trust;
  and that the advisory and/or management fees paid by the Fund/Trust, taking
  into account any applicable agreed-upon fee waivers and breakpoints, had
  represented reasonable compensation to the Previous Investment Adviser in
  light of the services provided, the costs to the Previous Investment
  Adviser of providing those services, economies of scale, the fees and other
  expenses paid by similar funds (including information provided by Lipper
  Inc. ["Lipper"]), and such other matters as the directors/trustees had
  considered relevant in the exercise of their reasonable judgment; and

* that Merrill Lynch had agreed to pay all expenses of the Fund and Trust in
  connection with the Board's consideration of the BlackRock Investment
  Advisory Agreements and related agreements and all costs of shareholder
  approval of the BlackRock Investment Advisory Agreements and as a result
  the Fund and the Trust would bear no costs in obtaining shareholder
  approval of the BlackRock Investment Advisory Agreements.



BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



Disclosure of New Investment Advisory Agreement (continued)


Certain of these considerations are discussed in more detail below.

In its review of the respective BlackRock Investment Advisory Agreements, each
Board assessed the nature, quality and scope of the services to be provided to
the Fund and the Trust by the personnel of BlackRock Advisors and its
affiliates, including administrative services, shareholder services, oversight
of fund accounting, marketing services and assistance in meeting legal and
regulatory requirements. In its review of the respective BlackRock Investment
Advisory Agreement, each Board also considered a range of information in
connection with its oversight of the services to be provided by BlackRock
Advisors and its affiliates. Among the matters considered were: (a) fees (in
addition to management fees) to be paid to BlackRock Advisors and its
affiliates by the Fund and the Trust; (b) Fund and Trust operating expenses
paid to third parties; (c) the resources devoted to and compliance reports
relating to the Fund's and the Trust's investment objective, policies and
restrictions, and their compliance with their Code of Ethics and BlackRock
Advisors' compliance policies and procedures; and (d) the nature, cost and
character of non-investment management services to be provided by BlackRock
Advisors and its affiliates.

In the period prior to the Board meetings to consider renewal of the Previous
Investment Advisory Agreements, each Board had requested and received
materials specifically relating to the Previous Investment Advisory
Agreements. These materials included (a) information compiled by Lipper on the
fees and expenses and the investment performance of the Fund as compared to a
comparable group of funds as classified by Lipper; (b) a discussion by the
Fund's/Trust's portfolio management team on investment strategies used by the
Fund/Trust during its most recent fiscal year; (c) information on the
profitability to the Previous Investment Adviser of the Previous Investment
Advisory Agreements and other payments received by the Previous Investment
Adviser and its affiliates from the Fund and the Trust; and (d) information
provided by the Previous Investment Adviser concerning services related to the
valuation and pricing of the Trust's portfolio holdings, allocation of Trust
brokerage fees, the Trust's portfolio turnover statistics, and direct and
indirect benefits to the Previous Investment Adviser and its affiliates from
their relationship with the Fund and the Trust.

In its deliberations, each Board considered information received in connection
with its most recent approval of the continuance of the respective Previous
Investment Advisory Agreement, in addition to information provided by BlackRock
and BlackRock Advisors in connection with their evaluation of the terms and
conditions of the BlackRock Investment Advisory Agreements. The directors/
trustees did not identify any particular information that was all-important
or controlling, and each director/trustee attributed different weights to the
various factors. The directors/trustees made their determinations separately
in respect of the Fund and the Trust. Each Board, including a majority of the
Board's independent directors/trustees, concluded that the terms of the
respective BlackRock Investment Advisory Agreement are appropriate, that the
fees to be paid are reasonable in light of the services to be provided to the
Fund/Trust, and that the BlackRock Investment Advisory Agreement should be
approved and recommended to Fund/Trust shareholders.

Nature, Quality and Extent of Services Provided--Each Board reviewed the
nature, quality and extent of services provided by the Previous Investment
Adviser, including the investment advisory services and the resulting
performance of the Fund and the Trust, as well as the nature, quality and
extent of services expected to be provided by BlackRock Advisors. Each Board
focused primarily on the Previous Investment Adviser's investment advisory
services and the investment performance of the Fund and the Trust, but also
considered certain areas in which both the Previous Investment Adviser and the
Fund/Trust received services as part of the Merrill Lynch complex. Each Board
compared the Fund's performance - both including and excluding the effects of
fees and expenses - to the performance of a comparable group of mutual funds,
and the performance of a relevant index or combination of indexes. While each
Board reviews performance data at least quarterly, consistent with the
Previous Investment Adviser's investment goals, the Board attaches more
importance to performance over relatively long periods of time, typically
three to five years.



BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors under the BlackRock Investment Advisory Agreements, each
Board considered, among other things, the expected impact of the Transaction
on the operations, facilities, organization and personnel of New BlackRock and
how it would affect the Fund and the Trust; the ability of BlackRock Advisors
to perform its duties after the Transaction; and any anticipated changes to
the investment and other practices of the Fund or the Trust. The directors/
trustees considered the fact that it was being proposed that the Fund acquire
the assets and liabilities of the BlackRock Intermediate Term Portfolio of
BlackRock Bond Fund, Inc., as part of a reorganization.

Each Board was given information with respect to the potential benefits to the
Fund and the Trust and their shareholders from having access to BlackRock's
state of the art technology and risk management analytic tools, including the
investment tools provided under the BlackRock Solutions brand name.

Each Board was advised that, as a result of Merrill Lynch's equity interest in
BlackRock after the Transaction, the Fund and the Trust would continue to be
subject to restrictions concerning certain transactions involving Merrill
Lynch affiliates (for example, transactions with a Merrill Lynch broker-dealer
acting as principal) absent revised or new regulatory relief. Each Board was
advised that a revision of existing regulatory relief with respect to these
restrictions was being sought from the Securities and Exchange Commission and
was advised of the possibility of receipt of such revised regulatory relief.

Based on their review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, the directors/
trustees determined that the nature and quality of services to be provided to
the Fund/Trust under the BlackRock Investment Advisory Agreements were
expected to be as good as or better than that provided under the Previous
Investment Advisory Agreements. It was noted, however, that changes in
personnel were expected to follow the Transaction and the combination of the
operations of the Previous Investment Adviser and its affiliates with those of
BlackRock. The directors/trustees noted that if portfolio managers or other
personnel were to cease to be available prior to the closing of the
Transaction, each Board would consider all available options, including
seeking the investment advisory or other services of BlackRock affiliates.
Accordingly, each Board concluded that, overall, the Board was satisfied at
the present time with assurances from BlackRock and BlackRock Advisors as to
the expected nature, quality and extent of the services to be provided to the
Fund/Trust under the BlackRock Investment Advisory Agreements.

Costs of Services Provided and Profitability--It was noted that, in
conjunction with its recent review of the respective Previous Investment
Advisory Agreement, each Board had received, among other things, a report from
Lipper comparing the Fund's fees and expenses to those of a peer group
selected by Lipper, and information as to the fees charged by the Previous
Investment Adviser or its affiliates to other registered investment company
clients for investment management services. Each Board reviewed the
Fund's/Trust's contractual management fee rate and actual management fee rate
as a percentage of total assets at common asset levels - the actual rate
includes advisory fees and the effects of any fee waivers - compared to the
other funds in the Fund's Lipper category. Each Board also compared the
Fund's/Trust's total expenses to those of other comparable funds. The
information showed that the Fund/Trust had fees and expenses within the range
of fees and expenses of comparable funds. Each Board considered the services
to be provided by and the fees to be charged by BlackRock Advisors to other
funds with similar investment mandates and noted that the fees charged by
BlackRock Advisors in those cases, including fee waivers and expense
reimbursements, were generally comparable to those being charged to the
Fund/Trust. The Boards also noted that, as a general matter, according to the
information provided by BlackRock, fees charged to institutional clients were
lower than the fees charged to the Fund, but BlackRock Advisors provided less
extensive services to such clients. Each Board concluded that the
Fund's/Trust's management fee and fee rate and overall expense ratio are
reasonable compared to those of other comparable funds.

In evaluating the costs of the services to be provided by BlackRock Advisors
under the BlackRock Investment Advisory Agreements, each Board considered,
among other things, whether advisory fees or other expenses would change as a
result of the Transaction. Based on their review of the materials provided and
the fact that each BlackRock Investment Advisory Agreement is substantially
similar to the respective Previous Investment Advisory Agreement in all
material respects, including the rate of compensation, each Board determined
that the Transaction should not increase the total fees payable, including any
fee waivers and expense reimbursements, for advisory and administrative
services. Each Board noted that it was not possible to predict how the
Transaction would affect BlackRock Advisors' profitability from its
relationship with the Fund and the Trust.



BLACKROCK BOND FUND OF BLACKROCK BOND FUND, INC.             SEPTEMBER 30, 2006



Disclosure of New Investment Advisory Agreement (concluded)


Each Board discussed with BlackRock Advisors its general methodology to be
used in determining New BlackRock's profitability with respect to its
relationship with the Fund and the Trust. The directors/trustees noted that
they expect to receive profitability information from BlackRock Advisors on at
least an annual basis and thus be in a position to evaluate whether any
adjustments in the Fund's/Trust's fees and/or fee breakpoints would be
appropriate.

Fees and Economies of Scale--Each Board considered the extent to which
economies of scale might be realized as the assets of the Fund and the Trust
increase and whether there should be changes in the management fee rate or
structure in order to enable the Fund and the Trust to participate in these
economies of scale. Each Board determined that changes were not currently
necessary.

In reviewing the Transaction, each Board considered, among other things,
whether advisory fees or other expenses would change as a result of the
Transaction. Based on the fact that the BlackRock Investment Advisory
Agreements are substantially similar to the Previous Investment Advisory
Agreements in all material respects, including the rates of compensation, each
Board determined that as a result of the Transaction, the Fund's/Trust's total
advisory fees would be no higher than the fees under the Previous Investment
Advisory Agreements. Each Board noted that in conjunction with the most recent
deliberations concerning the Previous Investment Advisory Agreements, the
directors/trustees had determined that the total fees for advisory and
administrative services for the Fund and the Trust were reasonable in light of
the services provided. It was noted that in conjunction with the recent review
of the Previous Investment Advisory Agreements, the Boards had received, among
other things, a report from Lipper comparing the Fund's/Trust's fees, expenses
and performance to those of a peer group selected by Lipper, and information
as to the fees charged by the Previous Investment Adviser to other registered
investment company clients for investment management services. Each Board
concluded that because the rates for advisory fees for the Fund/Trust would be
no higher than the fee rates in effect at the time, the proposed management
fee structures, including any fee waivers, were reasonable and that no
additional changes were currently necessary.

Fall-Out Benefits--In evaluating the fall-out benefits to be received by
BlackRock Advisors under the BlackRock Investment Advisory Agreements, each
Board considered whether BlackRock Advisors would experience such benefits to
the same extent that the Previous Investment Adviser was experiencing such
benefits under the Previous Investment Advisory Agreements. Based on their
review of the materials provided, including materials received in connection
with their most recent approval of the continuance of the Previous Investment
Advisory Agreements, and their discussions with management of the Previous
Investment Adviser and BlackRock, the directors/trustees determined that
BlackRock Advisors' fall-out benefits could include increased ability for
BlackRock to distribute shares of its funds and other investment products and
to obtain research services using the Trust's portfolio transaction brokerage
commissions. Each Board noted that fall-out benefits were difficult to
quantify with certainty at this time, and indicated that the Board would
continue to evaluate them going forward.

Investment Performance--Each Board considered investment performance for the
Fund and the Trust. Each Board compared the Fund's/Trust's performance - both
including and excluding the effects of fees and expenses - to the performance
of a comparable group of mutual funds, and the performance of a relevant index
or combination of indexes. The comparative information received from Lipper
showed Fund performance at various levels within the range of performance of
comparable funds over different time periods. While each Board reviews
performance data at least quarterly, consistent with the Previous Investment
Adviser's investment goals, the Board attaches more importance over relatively
long periods of time, typically three to five years. Each Board believed the
Fund's performance was satisfactory. Also, each Board took into account the
investment performance of funds advised by BlackRock Advisors. Each Board
considered comparative information from Lipper which showed that the
performance of the funds advised by BlackRock Advisors was within the range of
performance of comparable funds over different time periods. Each Board noted
BlackRock's considerable investment management experience and capabilities,
but was unable to predict what effect, if any, consummation of the Transaction
would have on the future performance of the Fund.

Conclusion--After the independent directors of the Fund and the independent
trustees of the Trust deliberated in executive session, each entire Board,
including the independent directors/trustees, approved the respective
BlackRock Investment Advisory Agreement, concluding that the advisory fee rate
was reasonable in relation to the services provided and that the BlackRock
Investment Advisory Agreement was in the best interests of the Fund's/Trust's
shareholders. In approving the respective BlackRock Investment Advisory
Agreement, each Board noted that it anticipated reviewing the continuance of
the agreement in advance of the expiration of the initial two-year period.


New BlackRock Sub-Advisory Agreement--Matters Considered by the Boards

At an in-person meeting held on August 14-16, 2006, the Board of Directors of
the Fund, including the independent directors, and the Board of Trustees of
the Trust, including the independent trustees, discussed and approved the
respective sub-advisory agreement (each, a "BlackRock Sub-Advisory Agreement"
and, together, the "BlackRock Sub-Advisory Agreements") between BlackRock
Advisors and its affiliate, BlackRock Financial Management, Inc. (the "Sub-
Adviser") for each of the Fund and the Trust. The BlackRock Sub-Advisory
Agreements became effective on September 29, 2006, at the same time the
BlackRock Investment Advisory Agreements became effective.

Pursuant to the BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a
monthly fee from BlackRock Advisors equal to 59% of the advisory fee received
by BlackRock Advisors from the Fund and the Trust. BlackRock Advisors pays the
Sub-Adviser out of its own resources, and there is no increase in Fund or
Trust expenses as a result of the BlackRock Sub-Advisory Agreements.

In approving each respective BlackRock Sub-Advisory Agreement at the August in-
person meeting, each Board reviewed its considerations in connection with its
approval of the BlackRock Investment Advisory Agreements in May 2006. The
Boards relied on the same information and considered the same factors as those
discussed above in connection with the approval of the BlackRock Investment
Advisory Agreements, and came to the same conclusions. In reviewing the sub-
advisory fee rate provided in each BlackRock Sub-Advisory Agreement, each
Board noted the fact that both BlackRock Advisors and the Sub-Adviser have
significant responsibilities under their respective advisory agreements.
BlackRock Advisors remains responsible for oversight of the Fund's and the
Trust's operations and administration, and the Sub-Adviser provides advisory
services to the Fund/Trust and is responsible for the day-to-day management of
the Fund's/Trust's portfolio under the BlackRock Sub-Advisory Agreements. The
Boards also took into account the fact that there is no increase in total
advisory fees paid by the Fund or the Trust as a result of the BlackRock Sub-
Advisory Agreements. Under all of the circumstances, each Board concluded that
it was a reasonable allocation of fees for the Sub-Adviser to receive 59% of
the advisory fee paid to BlackRock Advisors.

After the independent directors of the Fund and the independent trustees of
the Trust deliberated in executive session, each entire Board, including the
independent directors/trustees, approved the respective BlackRock Sub-Advisory
Agreement, concluding that the sub-advisory fee was reasonable in relation to
the services provided and that the BlackRock Sub-Advisory Agreement was in the
best interests of Fund/Trust shareholders.

            (e)(1) The registrant's audit committee (the "Committee") has
            adopted policies and procedures with regard to the pre-approval of
            services.  Audit, audit-related and tax compliance services
            provided to the registrant on an annual basis require specific pre-
            approval by the Committee.  The Committee also must approve other
            non-audit services provided to the registrant and those non-audit
            services provided to the registrant's affiliated service providers
            that relate directly to the operations and the financial reporting
            of the registrant.  Certain of these non-audit services that the
            Committee believes are a) consistent with the SEC's auditor
            independence rules and b) routine and recurring services that will
            not impair the independence of the independent accountants may be
            approved by the Committee without consideration on a specific case-
            by-case basis ("general pre-approval").  However, such services
            will only be deemed pre-approved provided that any individual
            project does not exceed $5,000 attributable to the registrant or
            $50,000 for all of the registrants the Committee oversees.  Any
            proposed services exceeding the pre-approved cost levels will
            require specific pre-approval by the Committee, as will any other
            services not subject to general pre-approval (e.g., unanticipated
            but permissible services).  The Committee is informed of each
            service approved subject to general pre-approval at the next
            regularly scheduled in-person board meeting.

            (g) Fiscal Year Ending September 30, 2006 - $3,050,250
                Fiscal Year Ending September 30, 2005 - $6,827,388

            (h) The registrant's audit committee has considered and determined
            that the provision of non-audit services that were rendered to the
            registrant's investment adviser and any entity controlling,
            controlled by, or under common control with the investment adviser
            that provides ongoing services to the registrant 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.

            Shareholders who wish to recommend a nominee should send
            nominations which include biographical information and sets forth
            the qualifications of the proposed nominee to the registrant's
            Secretary.  There have been no material changes to these
            procedures.

            as of a date within 90 days prior to the filing date of this

11(b) -     There were no changes in the registrant's internal control over
            financial reporting (as defined in Rule 30a-3(d) under the Act
            (17 CFR 270.30a-3(d)) that occurred during the second fiscal half-
            year of the period covered by this report that has materially
            affected, or is reasonably likely to materially affect, the
            registrant's internal control over financial reporting.
