A Letter to Shareholders


Dear Shareholder

The 12 months from May 2006 to May 2007 took global equities on an
extraordinary ride. A sharp correction at the start, the first in almost four
years, gave way to strength in the latter half of 2006 and early 2007. This
rally was interrupted by another set-back at the end of February, before
markets resumed their upward march through May 31. Ultimately, the tailwinds
of a generally favorable global economic backdrop, tame inflation, relatively
low interest rates, still positive earnings growth and attractive valuations
prevailed over the headwinds of a weakening U.S. economy, slowing housing
market, escalating geopolitical concerns and high energy prices. In fact, both
the Dow Jones Industrial Average and the Standard & Poor's 500 Index touched
new record highs following the most recent correction.

Mixed economic signals led to volatile behavior in fixed income markets as
well. However, from the beginning of 2007 through May 31, short-term bond
yields generally fell while longer-term yields increased. This resulted in
some re-steepening of the yield curve, which had been flat to inverted
throughout 2006. On a year-over-year basis, yields on 30-year Treasury bonds
fell 20 basis points (.20%) and 10-year yields fell 22 basis points, while
bond prices correspondingly rose. Meanwhile, the Federal Reserve Board (the
Fed) has left the federal funds rate at 5.25% since first pausing in August
2006. While first-quarter gross domestic product growth of 0.6% represented
the slowest rate of expansion since 2002, the Fed reiterated its view that
inflation, not a slowing economy, remains its primary concern. Many observers
interpreted the Fed's reaction to mean that the economy has hit its low and is
bound for renewed strength, therefore reducing the likelihood of an interest
rate cut in the near future.

Against this backdrop, most major market indexes posted positive returns for
the annual and semi-annual reporting periods ended May 31, 2007, with equities
exhibiting particular strength:

A Discussion With Your Fund's Portfolio Managers


Fund performance during the period reflected an early decline in commodity
prices, particularly oil and natural gas prices, which could not be overcome
by later gains.


What is the Fund's investment objective?

The Fund seeks positive long-term total return, primarily through investment
in commodity-linked derivative instruments and short-term debt obligations.
The commodity-linked derivative instruments in which the Fund may invest
include hybrid instruments, such as structured notes or commodity index-linked
notes, whose principal and/or interest payments are tied to the value of
commodities, commodity futures contracts or the performance of commodity
indexes. The debt obligations in which the Fund invests are primarily
investment grade, fixed or floating rate debt securities of any maturity.


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

For the six-month period ended May 31, 2007, BlackRock Commodity Strategies
Fund's (formerly BlackRock Real Investment Fund) Institutional, Investor A,
Investor B and Investor C Shares had net total returns of -2.59%, -2.71%,
- -3.01% and -3.05%, respectively. (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.) For
the same period, the Goldman Sachs Commodity Total Return Index returned
- -4.07%. As of March 30, 2007, the Fund's benchmark changed from the Goldman
Sachs Commodity Total Return Index to the Dow Jones-AIG Total Return Commodity
Index, which returned +1.07% for the six-month period. Importantly, the
indexes are used to illustrate the performance of the overall commodities
markets, but are not necessarily a comparable measure of the Fund's results.
The Fund is designed to tap into the performance of the commodities markets
and will generally track the markets' trends. However, it is a fixed income
investment and must fund the cost of gaining that commodity exposure through
the creation of commodity-linked notes. This inherent cost will necessarily
impact the Fund's results relative to the indexes.

Falling energy and commodity prices continued in the beginning of the
reporting period and contributed to the negative absolute performance of the
benchmarks and the Fund. The decline was led by the price of oil, which dipped
sharply and flirted with $50 per barrel in January before recovering to
roughly $64 per barrel by the end of the period. Natural gas prices started
close to $9 per British thermal unit (Btu) and also fell precipitously through
January, but recovered in concert with oil to end the period just shy of $8
per Btu. The early decline in energy prices was attributable to a mild start
to the winter heating season, a slowing U.S. economy and high inventory
levels. The recovery in oil prices that began in February was due to such
domestic factors as the return of normal winter temperatures and anticipation
of another gasoline-intensive summer season, as well as international issues
like the tensions surrounding the nuclear ambitions of oil-rich Iran.

Meanwhile, the metals markets exhibited a similar pattern of early decline
followed by an upswing starting in February. While silver was down to $13.47
per ounce at period-end versus $13.93 at the start, gold gained ground, moving
from $648 per ounce to $661 per ounce. Copper prices were down from roughly
$7,030 per ton six months ago to $6,787 per ton at period-end. The rise in
metals prices in the latter part of the period was attributable to a resumption
of Chinese growth and subsequent resource consumption, as well as supply-side
pressure in the form of threatened mine strikes in both Peru and Indonesia.

Because we use credit-sensitive debt securities to provide yield enhancement
for the portfolio, Fund returns also are influenced by the performance of the
credit markets. During the six-month reporting period, there was considerable
turmoil in the subprime mortgage market as loan defaults followed interest
rates higher. While the credit portion of the portfolio focused primarily on
asset-backed securities, including a significant position in home equity
product, our preference for higher-quality credits kept the Fund largely
insulated from the subprime woes.


What changes were made to the portfolio during the period?

As mentioned earlier, the Fund's benchmark changed from the Goldman Sachs
Commodity Total Return Index to the Dow Jones-AIG Total Return Commodity
Index. The overall Fund strategy remained the same as we sought to maintain
33% of total assets invested in leveraged commodity-linked notes, providing
100% commodity exposure to shareholders. The remaining 67% of net assets was
invested in our enhanced cash strategy designed to outpace the London
InterBank Offered Rate.



BLACKROCK COMMODITY STRATEGIES FUND                                MAY 31, 2007



Following the benchmark change, we implemented a new enhanced commodity
strategy in which 50% of the Fund's commodity exposure is invested in the
eight commodities in the Index (excluding gold and silver) that exhibit the
highest basis (that is, the difference between spot and futures prices). The
remaining 50% of the commodity exposure is invested in the nine commodities
within the Index that exhibit the highest price momentum (based on 12-month
returns). In order to maintain the stated commodity exposure, the portfolio is
rebalanced monthly based on the most recent rolling 12-month Index data.

The most notable activity in the portfolio during the six-month period was the
roll out of the new commodity strategy. In order to achieve the desired
exposure to the new benchmark, the Dow Jones-AIG Total Return Commodity Index,
we sold all of the existing commodity-linked notes from the portfolio and
purchased new notes that were structured to pay returns based on the new
benchmark. We also continued to fund the cost of acquiring the commodity-
linked exposure with income generated from low-duration fixed income
investments, such as agency debt, structured finance securities and other
corporate and mortgage products.


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

At period-end, the Fund's fixed income exposure stood at approximately 67% of
overall assets, broken down as follows: 14% in floating rate home equity
loans; 23% in collateralized mortgage obligations; 9% in investment grade
corporate bonds and 21% in 30-year generic pass-through securities. The Fund
ended the period with a credit profile of AA+.

The recovery in energy and commodity prices in recent months seems to confirm
that the earlier setbacks were short-term movements and commodities will be
long-term benefactors of global economic expansion. While volatility is likely
to continue in all markets for some time, commodities tend to perform opposite
of traditional asset classes and, therefore, provide diversification that is
essential under such economic conditions. Given its unique structure, the Fund
also offers shareholders access to securities that are not available to
individual investors on the open market.

Performance Data


About Fund Performance


Effective October 2, 2006, the Fund's Class A, Class B, Class C and Class I
Shares were redesignated Investor A, Investor B, Investor C and Institutional
Shares, respectively. As previously communicated to shareholders, new sales
charge schedules came into effect at the same time for certain of these
classes.

The Fund has multiple classes of shares:

* Institutional Shares are not subject to any sales charge. Institutional
Shares bear no ongoing distribution or service fees and are available only to
eligible investors.

* Investor A Shares incur a maximum initial sales charge (front-end load) of
5.25% and a service fee of 0.25% per year (but no distribution fee).

* Investor B Shares are subject to a maximum contingent deferred sales charge
of 4.50% declining to 0% after six years. In addition, Investor B Shares are
subject to a distribution fee of 0.75% per year and a service fee of 0.25% per
year. These shares automatically convert to Investor A Shares after
approximately eight years. (There is no initial sales charge for automatic
share conversions.) All returns for periods greater than eight years reflect
this conversion.

* Investor C Shares are subject to a distribution fee of 0.75% per year and a
service fee of 0.25% per year. In addition, Investor C Shares are subject to a
1% contingent deferred sales charge if redeemed within one year of purchase.

Performance information reflects past performance and does not guarantee
future results. Current performance may be lower or higher than the
performance data quoted. Refer to www.blackrock.com to obtain performance data
current to the most recent month-end. Performance results do not reflect the
deduction of taxes that a shareholder would pay on fund distributions or the
redemption of fund shares. Figures shown in each of the following tables
assume reinvestment of all dividends and capital gain distributions, if any,
at net asset value on the ex-dividend date. Investment return and principal
value of shares will fluctuate so that shares, when redeemed, may be worth
more or less than their original cost. Dividends paid to each class of shares
will vary because of the different levels of service, distribution and
transfer agency fees applicable to each class, which are deducted from the
income available to be paid to shareholders. The Fund's Manager has
voluntarily waived a portion of its fee. Without such waiver, the Fund's
returns 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 December 1, 2006 and
held through May 31, 2007) is intended to assist shareholders both in
calculating expenses based on an investment in the Fund and in comparing these
expenses with similar costs of investing in other mutual funds.

The 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
   (1.33% for Institutional, 1.58% for Investor A, 2.34% for Investor B and 2.34% for Investor C),
   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 LLC
   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 COMMODITY STRATEGIES FUND                                MAY 31, 2007



Notes to Financial Statements (Unaudited)   BlackRock Commodity Strategies Fund


1. Significant Accounting Policies:
On March 26, 2007, BlackRock Real Investment Fund was renamed BlackRock
Commodity Strategies Fund (the "Fund"). The Fund is registered under the
Investment Company Act of 1940, as amended, as a non-diversified, open-end
investment company. The Fund seeks to achieve its investment objective by
investing all of its assets in Master Real Investment Trust, which was renamed
Master Commodity Strategies Trust (the "Trust"), which has the same investment
objective and strategies as the Fund. Effective June 15, 2007, the Trust was
converted to a Delaware limited liability company and in accordance to the
Limited Liability Company Agreement was renamed Master Commodity Strategies
LLC (the "Master LLC"). The value of the Fund's investment in the Master LLC
reflects the Fund's proportionate interest in the net assets of the Master
LLC. The performance of the Fund is directly affected by the performance of
the Master LLC. The financial statements of the Master LLC, 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. These unaudited financial
statements reflect all adjustments, which are, in the opinion of management,
necessary to present a fair statement of the results of the interim period.
All such adjustments are of a normal, recurring nature. The percentage of the
Master LLC owned by the Fund at May 31, 2007 was 87.8%. The Fund offers
multiple classes of shares. Institutional Shares are sold only to certain
eligible investors. Investor A Shares are sold with a front-end sales charge.
Shares of Investor B and Investor C may be subject to a contingent deferred
sales charge. All classes of shares have identical voting, dividend,
liquidation and other rights and the same terms and conditions, except that
Investor A, Investor B and Investor C Shares bear certain expenses related to
the shareholder servicing of such shares, and Investor B and Investor C Shares
also bear certain expenses related to the distribution of such shares. Each
class has exclusive voting rights with respect to matters relating to its
shareholder servicing and distribution expenditures (except that Investor B
shareholders may vote on certain changes to the Investor A distribution plan).
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
LLC at fair value. Valuation of securities held by the Master LLC is discussed
in Note 1(a) of the Master LLC's Notes to Financial Statements, which are
included elsewhere in this report.

(b) Investment income and expenses--The Fund records daily its proportionate
share of the Master LLC'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) Prepaid registration fees--Prepaid registration fees are charged to
expense as the related shares are issued.

(e) Dividends and distributions--Dividends and distributions paid by the Fund
are recorded on the ex-dividend dates.

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

(g) Recent accounting pronouncements--In July 2006, the Financial Accounting
Standards Board released FASB Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes". FIN 48 provides guidance for how uncertain
tax positions should be recognized, measured, presented and disclosed in
financial statements. FIN 48 requires the evaluation of tax positions taken in
the course of preparing the Fund's tax returns to determine whether the tax
positions are "more-likely-than-not" of being sustained by the applicable tax
authority. Tax benefits of positions not deemed to meet the more-likely-than-
not threshold would be booked as a tax expense in the current year and
recognized as: a liability for unrecognized tax benefits; a reduction of an
income tax refund receivable; a reduction of deferred tax asset; an increase
in deferred tax liability; or a combination thereof. Adoption of FIN 48 is
required for the last net asset value calculation in the first required
financial statement reporting period for fiscal years beginning after December
15, 2006. The impact on the Fund's financial statements, if any, is currently
being assessed.



BLACKROCK COMMODITY STRATEGIES FUND                                MAY 31, 2007



Notes to Financial Statements (continued)   BlackRock Commodity Strategies Fund




In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS
157 and its impact on the Fund's financial statements, if any, has not been
determined.

In addition, in February 2007, FASB issued Statement of Financial Accounting
Standards No. 159, "The Fair Value Option for Financial Assets and Financial
Liabilities" ("FAS 159"), which is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also
elects to apply the provisions of FAS 157. FAS 159 permits entities to choose
to measure many financial instruments and certain other items at fair value
that are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is
evaluating the implications of FAS 159 and its impact on the Fund's financial
statements, if any, has not been determined.


2. Transactions with Affiliates:
The Fund has entered into an Administrative Agreement with BlackRock Advisors,
LLC (the "Administrator"), an indirect, wholly owned subsidiary of BlackRock,
Inc. The Fund pays a monthly fee at an annual rate of 0.50% of the Fund's
average net assets for the performance of administrative services (other than
investment advice and related portfolio activities) necessary for the
operation of the Fund. The Fund has entered into separate Distribution
Agreements and Distribution Plans with FAM Distributors, Inc. ("FAMD") and
BlackRock Distributors, Inc. and its affiliates ("BDI") (collectively, the
"Distributor"). FAMD is a wholly owned subsidiary of Merrill Lynch Group,
Inc., and BDI is an affiliate of BlackRock, Inc. Merrill Lynch & Co.,
Inc.("Merrill Lynch") and The PNC Financial Services Group, Inc. ("PNC") are
the principal owners of BlackRock, Inc.

In addition, the Administrator has agreed to voluntarily waive the
administration fees and/or reimburse expenses in order to cap total expenses
(excluding distribution fees and/or shareholder servicing fees) at 1.33%. For
the six months ended May 31, 2007, the Administrator earned fees of $151,571,
of which $129,259 was waived.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor
on-going service and distribution fees. The fees are accrued daily and paid
monthly at annual rates based upon the average daily net assets of the shares
as follows:


                                      Service          Distribution
                                          Fee                   Fee

Investor A                               .25%                    --
Investor B                               .25%                  .75%
Investor C                               .25%                  .75%


Pursuant to sub-agreements with each Distributor, broker dealers, including
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch and the Distributor, provide shareholder servicing
and distribution services to the Fund. The ongoing service fee compensates the
Distributors and each broker dealer (including MLPF&S) for providing
shareholder servicing to Investor A, Investor B and Investor C shareholders.
The ongoing distribution fee compensates each Distributor and MLPF&S for
providing shareholder and distribution-related services to Investor B and
Investor C shareholders.

For the six months ended May 31, 2007, FAMD earned underwriting discounts and
direct commissions and MLPF&S earned dealer concessions on sales of the Fund's
Investor A Shares as follows:

                                         FAMD                MLPF&S

Investor A                               $612                $8,252

For the six months ended May 31, 2007, MLPF&S received contingent deferred
sales charges of $15,991 and $13,764 relating to transactions in Investor B

deferred sales charges of $65 relating to transactions in Investor C Shares.

The Administrator maintains a call center, which is responsible for providing
certain shareholder services to the Fund, such as responding to shareholder
inquiries and processing transactions based upon instructions from
shareholders with respect to the subscription and redemption of fund shares.
During the six months ended May 31, 2007, the following amounts have been
accrued by the Fund to reimburse the Administrator for costs incurred in
running the call center, which are a component of the transfer agent fees in
the accompanying Statements of Operations.

Notes to Financial Statements (Unaudited)       Master Commodity Strategies LLC


1. Significant Accounting Policies:
On March 29, 2007, Master Real Investment Trust was renamed Master Commodity
Strategies Trust (the "Trust"). The Trust is registered under the Investment
Company Act of 1940, as amended, and is organized as a Delaware statutory
trust. Effective June 15, 2007, the Trust was converted to a Delaware limited
liability company and in accordance to the Limited Liability Company Agreement
(the "LLC Agreement") was renamed Master Commodity Strategies LLC (the "Master
LLC").The Declaration of Trust permits the Trustees (and after June 15, 2007,
the LLC Agreement permits the Directors) to issue non-transferable interests
in the Trust/Master LLC, subject to certain limitations. Throughout this
report the Trust and the Master LLC are referred to as the Master LLC and the
Board of Trustees is referred to as the Board of Directors. The Master LLC's
financial statements are prepared in conformity with U.S. generally accepted
accounting principles, which may require the use of management accruals and
estimates. These unaudited financial statements reflect all adjustments, which
are, in the opinion of management, necessary to present a fair statement of
the results for the interim period. All such adjustments are of a normal,
recurring nature. Actual results may differ from these estimates. The
following is a summary of significant accounting policies followed by the
Master LLC.

(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 markets or on the basis of yield equivalents as obtained by the Master
LLC's pricing service from one or more dealers that make markets in the
securities. 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. Options traded in the OTC markets are
valued at the last asked price (options written) or the last bid price
(options purchased). Swap agreements are valued based upon quoted fair
valuations received daily by the Master LLC from a pricing service or
counterparty. Valuation of short-term investment vehicles is generally based
upon the net asset value of the underlying investment vehicle or amortized
cost. Repurchase agreements are valued at cost plus accrued interest. The
Master LLC employs pricing services to provide certain securities prices for
the Master LLC. Securities and assets for which market quotations are not
readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Master LLC, including
valuations furnished by the pricing services retained by the Master LLC, which
may utilize a matrix system for valuations. The procedures of the pricing
service and its valuations are reviewed by the officers of the Master LLC
under the general direction of the Board of Directors. Such valuations and
procedures will be reviewed periodically by the Board of Directors of the
Master LLC.

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

Generally, trading in foreign securities, as well as U.S. government
securities, money market instruments and certain fixed income securities is
substantially completed each day at various times prior to the close of
business on the New York Stock Exchange ("NYSE"). The values of such
securities used in computing the net assets of the Master LLC are determined
as of such times. Foreign currency exchange rates will generally be determined
as of the close of business on the NYSE. Occasionally, events affecting the
values of such securities and such exchange rates may occur between the times
at which they are determined and the close of business on the NYSE that may
not be reflected in the computation of the Master LLC's net assets. If events
(for example, a company announcement, market volatility or a natural disaster)
occur during such periods that are expected to materially affect the value of
such securities, those securities may be valued at their fair value as
determined in good faith by the Master LLC's Board of Directors or by
BlackRock Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary
of BlackRock, Inc., using a pricing service and/or procedures approved by the
Master LLC's Board of Directors.

Notes to Financial Statements (continued)       Master Commodity Strategies LLC


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

* Hybrid instruments--The Master LLC may invest in hybrid instruments,
including structured notes and commodity-linked notes. The principal and/or
interest payments on these hybrid instruments are linked to the value of
commodities, commodity futures contracts, or the performance of one or more
indexes or other readily measurable economic variables. The principal value of
the hybrid instruments, and/or the value of the interest that they pay, will
rise or fall in response to changes in the values of the underlying
commodities, commodity futures contracts, or commodity indexes. Although these
hybrid instruments are primarily debt obligations, they indirectly provide
exposure to changes in the value of the underlying commodities.

* Options--The Master LLC may purchase and write covered call and put options.
When the Master LLC writes an option, an amount equal to the premium received
by the Master LLC 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 LLC enters into a closing transaction), the Master LLC 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
premium paid or received).

Written and purchased options are non-income producing investments.

* Financial futures contracts--The Master LLC 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 LLC 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 LLC 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 LLC as unrealized gains or losses. When the contract is
closed, the Master LLC 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.

* Swaps--The Master LLC may enter into swap agreements, which are OTC
contracts in which the Master LLC 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 LLC are recorded in the accompanying Statement of
Operations as realized gains or losses, respectively. Gains or losses are also
realized upon termination of the swap agreements. Swaps are marked-to-market
daily and changes in value are recorded as unrealized appreciation
(depreciation). Risks include changes in the returns of the underlying
instruments, failure of the counterparties to perform under the contracts'
terms and the possible lack of liquidity with respect to the swap agreements.

(c) Income taxes--The Master LLC is classified as a partnership for federal
income tax purposes. As such, each investor in the Master LLC is treated as
owner of its proportionate share of the net assets, income, expenses and
realized and unrealized gains and losses of the Master LLC. Therefore, no
federal income tax provision is required. It is intended that the Master LLC's
assets will be managed so an investor in the Master LLC can satisfy the
requirements of Subchapter M of the Internal Revenue Code.

(d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis.

Notes to Financial Statements (continued)       Master Commodity Strategies LLC


(e) Securities lending--The Master LLC 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 LLC and any additional required collateral is delivered
to the Master LLC on the next business day. Where the Master LLC receives
securities as collateral for the loaned securities, it collects a fee from the
borrower. The Master LLC typically receives the income on the loaned
securities but does not receive the income on the collateral. Where the Master
LLC 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 LLC 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 LLC could experience delays and costs in
gaining access to the collateral. The Master LLC 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.

(f) TBA Commitments--The Master LLC may enter into to be announced ("TBA")
commitments to purchase or sell securities for a fixed price at a future date.
TBA commitments are considered securities in themselves, and involve a risk of
loss if the value of the security to be purchased/sold declines/increases
prior to the settlement date, which is in addition to the risk of decline in
the value of the Master LLC's other assets. Unsettled TBA commitments are
valued at the current market value of the underlying securities, according to
the procedures described under "Valuation of investments."

(g) Recent accounting pronouncements--In July 2006, the Financial Accounting
Standards Board released FASB Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes". FIN 48 provides guidance for how uncertain
tax positions should be recognized, measured, presented and disclosed in
financial statements. FIN 48 requires the evaluation of tax positions taken in
the course of preparing the Master LLC's tax returns to determine whether the
tax positions are "more-likely-than-not" of being sustained by the applicable
tax authority. Tax benefits of positions not deemed to meet the more-likely-
than-not threshold would be booked as a tax expense in the current year and
recognized as: a liability for unrecognized tax benefits; a reduction of an
income tax refund receivable; a reduction of deferred tax asset; an increase
in deferred tax liability; or a combination thereof. Adoption of FIN 48 is
required for the last net asset value calculation in the first required
financial statement reporting period for fiscal years beginning after December
15, 2006. The impact on the Master LLC's financial statements, if any, is
currently being assessed.

In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS
157 and its impact on the Master LLC's financial statements, if any, has not
been determined.

In addition, in February 2007, FASB issued Statement of Financial Accounting
Standards No. 159, "The Fair Value Option for Financial Assets and Financial
Liabilities" ("FAS 159"), which is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also
elects to apply the provisions of FAS 157. FAS 159 permits entities to choose
to measure many financial instruments and certain other items at fair value
that are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is
evaluating the implications of FAS 159 and its impact on the Master LLC's
financial statements, if any, has not been determined.


2. Investment Advisory Agreement Transactions with Affiliates:
The Master LLC has entered into an Investment Advisory Agreement with the
Manager. Merrill Lynch & Co., Inc. ("Merrill Lynch") and The PNC Financial
Services Group are the principal owners of BlackRock, Inc.

Notes to Financial Statements (concluded)       Master Commodity Strategies LLC


The Manager is responsible for the management of the Master LLC's investments
and provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Master LLC. For such services, the
Master LLC pays a monthly fee based upon the average daily value of the Master
LLC's net assets at the annual rate of 0.50%. In addition, the Manager has
entered into Sub-Advisory Agreements with BlackRock Investment Management, LLC
("BIM") and BlackRock Financial Management, Inc., both affiliates of the
Manager, under which the Manager pays each Sub-Adviser for services it
provides a fee equal to a percentage paid by the Master LLC to the Manager.

The Master LLC has received an exemptive order from the Securities and
Exchange Commission permitting it to lend portfolio securities to Merrill
Lynch, Pierce, Fenner & Smith Incorporated, or its affiliates. Pursuant to
that order, the Master LLC has retained BIM, an affiliate of the Manager, as
the securities lending agent for a fee based on a share of the returns on
investment of cash collateral. BIM may, on behalf of the Master LLC, invest
cash collateral received by the Master LLC for such loans, among other things,
in a private investment company managed by the Manager or in registered money
market funds advised by the Manager or its affiliates.

For the six months ended May 31, 2007, the Master LLC reimbursed the Manager
$877 for certain accounting services.

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

4. Short-Term Borrowings:
The Master LLC, along with certain other funds managed by the Manager and its
affiliates, is a party to a $500,000,000 credit agreement with a group of
lenders. The Master LLC may borrow under the credit agreement to fund
shareholder redemptions and for other lawful purposes other than for leverage.
The Master LLC may borrow up to the maximum amount allowable under the Master
LLC's current prospectus and statement of additional information, subject to
various other legal, regulatory or contractual limits. On November 22, 2006,
the credit agreement was renewed for one year under substantially the same
terms. The Master LLC pays a commitment fee of .06% per annum based on the
Master LLC's pro rata share of the unused portion of the credit agreement.
Amounts borrowed under the credit agreement bear interest at a rate equal to,
at each fund's election, the federal funds rate plus .35% or a base rate as
defined in the credit agreement. The Master LLC did not borrow under the
credit agreement during the six months ended May 31, 2007.
