A Letter to Shareholders


Dear Shareholder

As 2006 nears a conclusion, we are able to say it has been an interesting year
for investors. After a volatile start and far-reaching mid-year correction,
the financial markets regained some positive momentum through late summer and
into fall. For the six-month and 12-month periods ended November 30, 2006, the
major market indexes posted positive returns:




Total Returns as of November 30, 2006                                  6-month        12-month
                                                                                 
U.S. equities (Standard & Poor's 500 Index)                             +11.33%        +14.23%
Small cap U.S. equities (Russell 2000 Index)                            + 9.72         +17.43
International equities (MSCI Europe, Australasia, Far East Index)       +11.19         +28.20
Fixed income (Lehman Brothers Aggregate Bond Index)                     + 5.93         + 5.94
Tax-exempt fixed income (Lehman Brothers Municipal Bond Index)          + 4.53         + 6.12
High yield bonds (Credit Suisse High Yield Index)                       + 6.28         +11.53



After raising the target short-term interest rate 17 times between June 2004
and June 2006, the Federal Reserve Board (the Fed) finally opted to pause on
August 8. This left the federal funds rate at 5.25%, where it remained through
the September, October and December Federal Open Market Committee meetings. In
interrupting its two-year interest rate-hiking campaign, the Fed acknowledged
that economic growth is slowing, led by softness in the housing market.
However, the central bankers continue to take a cautionary position on
inflation, despite a decline in energy prices in the fall. At the time of this
writing, the price of crude oil was roughly $62 per barrel after reaching
nearly $78 per barrel in the summer.

Notwithstanding the mid-year correction, equity markets generally found
support in solid corporate earnings reports in the first three quarters of the
year. Overall corporate health, including strong company balance sheets,
helped to sustain robust dividend-distribution, share-buyback and merger-and-
acquisition activity. Many international equity markets fared equally well or
better, thanks in part to higher economic growth rates and low inflation.

In the U.S. bond market, prices declined (and yields correspondingly rose) for
much of the year as investors focused on decent economic activity and
inflation concerns. Bond prices began to improve (yields fell) in the summer
as the economy showed signs of weakening and the Fed paused. Notably, the
Treasury curve inverted periodically, a phenomenon typically associated with
periods of economic weakness. At the end of November, the one-month Treasury
bill offered the highest yield on the curve at 5.22%, while the 30-year
Treasury bond had a yield of 4.56%.

Amid the uncertainty inherent in the financial markets, we encourage you to
review your goals periodically with your financial professional and to make
portfolio changes, as needed. For additional insight and timely "food for
thought" for investors, we also invite you to visit Shareholder magazine at
www.blackrock.com/shareholdermagazine. We are pleased to make our investor-
friendly magazine available to you online.  We thank you for trusting
BlackRock with your investment assets, and we look forward to continuing to
serve your investment needs.


Sincerely,

BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006


A Discussion With Your Fund's Portfolio Managers


Fund performance during the period reflected a marked decline in commodity
prices, particularly oil and natural gas prices, in the latter half of the
fiscal year.


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-linked
notes, whose principal and/or interest payments are tied to the value of a
real asset or commodity index, such as the Goldman Sachs Commodity Total
Return Index. The debt obligations in which the Fund invests are primarily
investment grade, floating rate debt securities of any maturity.


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

For the 12-month period ended November 30, 2006, BlackRock Real Investment
Fund's Institutional, Investor A, Investor B and Investor C Shares had total
net returns of -6.52%, -6.77%, -7.46% and -7.50%, 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 -5.97%. Importantly, the Index is used to
illustrate the performance of the overall commodities markets, but is 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 Index.

Falling energy and commodity prices in the latter half of the fiscal year,
particularly in the final four months, contributed to the negative absolute
performance of the benchmark and the Fund. The decline was led by oil, with
the price per barrel reaching a record high near $78 per barrel in July before
falling to roughly $62 per barrel by the end of the period. Natural gas prices
also fell precipitously from a high of $48.21 per British thermal unit on July
31 to about $4.20 per British thermal unit by the end of September. After
climbing for several months, the decline in energy prices could be attributed
to an uneventful hurricane season, a slowing U.S. economy and concerns about
moderate winter temperatures.

Meanwhile, movements in the metals markets were more muted. Prices rose
precipitously in the first half of the fiscal year and leveled off somewhat in
the second half. The price of silver moved from more than $12 per ounce six
months ago to almost $14 per ounce at period-end, and gold from $645 per ounce
to $648 per ounce. Copper prices fell from roughly $7,900 per ton six months
ago to $7,030 per ton at period-end. The moderation in metals prices in the
latter half of the fiscal year can be attributed to a cyclical slowdown in
economic growth and a recent stabilization in inflation data.

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 12-month reporting period, the spread tightening
phenomenon that had contributed to strong performance in the credit markets
for some time began to moderate, leading us to favor higher-grade credit
product for yield enhancement, as we felt high-quality securities would be
somewhat less susceptible to any spread widening that might occur.
Specifically, we focused primarily on asset-back securities, which included a
significant position in home equity product. These generated excess return
above our target, the London InterBank Offered Rate (LIBOR), thereby
contributing to Fund performance for the period.


What changes were made to the portfolio during the period?

Our overall strategy remained the same throughout the period. We sought to
maintain 33% of total investments in leveraged commodity-linked notes,
providing 100% commodity exposure to shareholders. The remaining 67% was
invested in our enhanced cash strategy designed to outpace LIBOR.



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Early in the period, our commodity-linked notes issued by JP Morgan matured
from the portfolio, bringing our total exposure to the Goldman Sachs Commodity
Total Return Index from 100% to 85%. This reduced the beta of the portfolio
given our lower exposure to the commodities markets. In June, we reinvested
the proceeds from these maturing securities into the notes of a new issuer and
effectively returned the portfolio's exposure to the Index to 100%.

We 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.
With spreads at tight levels in nearly every market, it was increasingly
difficult to uncover value in credit product. One area that we found to offer
significant yield pick-up relative to the consumer sectors, particularly autos
and credit cards, was home equity product. As such, we focused our investment
in this area of the fixed income market.


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

At period-end, the portfolio's fixed income exposure stood at approximately
66% of overall assets, broken down as follows: 16% in adjustable rate
mortgages; 17% in asset-backed securities, including floating rate home equity
loans; 20% in collateralized mortgage obligations; 6% in Fannie Mae commercial
mortgage product; 4% in 30-year generic pass-throughs; 2% in Treasury
Inflation Linked Securities; and 1% in various debt securities. The Fund ended
the period with a credit profile of AAA.

Despite a decline in energy and commodity prices in recent months, we continue
to believe that commodities will be long-term benefactors of global economic
expansion. Although growth in the United States may be moderating, many global
economies - particularly developing economies - continue to experience robust
rates of expansion. Commodities will continue to be necessary to support these
developing nations' infrastructure and development needs. In addition,
commodities tend to perform opposite of traditional asset classes. Thus, the
Fund offers an opportunity to diversify a traditional portfolio of stocks and
bonds, thereby helping investors to prepare for a wider range of market and
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.

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 front-end 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 June 1, 2006 and held
through November 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
   (1.32% for Institutional, 1.57% for Investor A, 2.34% for Investor B and 2.34% for Investor C),
   multiplied by 183/365 (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
   trust 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 REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Notes to Financial Statements                    BlackRock Real Investment Fund


1. Significant Accounting Policies:
On September 29, 2006, Merrill Lynch Real Investment Fund was renamed
BlackRock Real Investment 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 (the "Trust"),
which has the same investment objective and strategies as the Fund. The value
of the Fund's investment in the Trust reflects the Fund's proportionate
interest in the net assets of the Trust. The performance of the Fund is
directly affected by the performance of the Trust. The financial statements of
the Trust, 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 Trust owned by the Fund at November 30, 2006
was 85.5%. The Fund offers multiple classes of shares. Effective October 2,
2006, Class I, Class A, Class B and Class C Shares were redesignated
Institutional, Investor A, Investor B and Investor C Shares, respectively.
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 account maintenance 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 account maintenance 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 Trust at
fair value. Valuation of securities held by the Trust is discussed in Note
1(a) of the Trust'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 Trust'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 Trust are
accounted for on a trade-date basis.

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

In addition, 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. Management is currently evaluating the implications
of FAS 157. At this time its impact on the Fund's financial statements has
not been determined.

(h) 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, $1,245,467 has been reclassified between accumulated net
realized capital losses and undistributed net investment income as a result of
permanent differences attributable to the characterization of realized gains
on certain debt instruments, swap agreements, and the reclassification of
distributions. These reclassifications have no effect on net assets or net
asset values per share.



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Notes to Financial Statements (continued)        BlackRock Real Investment Fund


2. Transactions with Affiliates:
On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and its affiliates, with BlackRock, Inc.
to create a new independent company. Merrill Lynch has a 49.8% economic
interest and a 45% voting interest in the combined company and The PNC
Financial Services Group, Inc. ("PNC"), has approximately a 34% economic and
voting interest. The new company operates under the BlackRock name and is
governed by a board of directors with a majority of independent members.

On August 31, 2006, shareholders of the Fund approved a new Investment
Advisory Agreement for the Trust with BlackRock Advisors, Inc. (the
"Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc. BlackRock
Advisors, Inc. was recently reorganized into a limited liability company and
renamed BlackRock Advisors, LLC. The new Investment Advisory Agreement between
the Trust and the Manager became effective on September 29, 2006. Prior to
September 29, 2006, MLIM was the Investment Adviser of the Trust and the Fund.
The general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect,
wholly owned subsidiary of Merrill Lynch, which is the limited partner.

Under the investment advisory agreements with the Fund from December 1, 2005 to
June 15, 2006, MLIM received a fee at the annual rate of 1.00% of the average
daily net assets of the Fund and contractually agreed to waive the Fund's
management fee in the amount of the Fund's share of the management fee paid by
the Trust. Effective June 16, 2006, the Fund entered into an administrative
agreement with MLIM. 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. As a result, the contractual waiver of the Trust's
portion of the management fee was discontinued. Effective September 29, 2006,
BlackRock Advisors, LLC became the administrator.

In addition, the Manager (and previously MLIM) has agreed to voluntarily waive
the investment advisory fees and/or reimburse expenses in order to cap total
expenses (excluding distribution fees and/or account maintenance fees
("service fees")) at 1.33%. The fees earned and waivers were as follows:


                                      Manager                  MLIM

Fees earned                           $63,371              $647,020
Waiver                                $31,928              $408,231


The Fund has also entered into separate Distribution Agreements and
Distribution Plans with FAM Distributors, Inc. ("FAMD") and BlackRock
Distributors, Inc. ("BDI") (collectively, the "Distributor"). FAMD is a wholly
owned subsidiary of Merrill Lynch Group, Inc. and BDI is an affiliate of
BlackRock, Inc.

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
ongoing service fees 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 an affiliate of the Distributor, also provide
account maintenance and distribution services to the Fund. The ongoing service
fee compensates the Distributors and each broker-dealer (including MLPF&S) for
providing account maintenance services to Investor A, Investor B and Investor
C shareholders. The ongoing distribution fee compensates the Distributors and
the broker-dealers for providing shareholder and distribution-related services
to Investor B and Investor C shareholders.

For the year ended November 30, 2006, FAMD, the Fund's sole Distributor until
September 29, 2006, and BDI for the period September 30, 2006 to November 30,
2006, earned underwriting discounts and MLPF&S earned dealer concessions on
sales of the Fund's Institutional and Investor A Shares as follows:


                                 FAMD         MLPF&S            BDI

Institutional               $      --     $      416        $    --
Investor A                  $  13,191     $  167,701        $    --

Notes to Financial Statements (continued)        BlackRock Real Investment Fund


For the year ended November 30, 2006, MLPF&S received contingent deferred
sales charges of $4,355 and $7,866 relating to transactions in Investor B and
Investor C Shares, respectively. Furthermore, MLPF&S received contingent
deferred sales charges of $28 relating to transactions subject to front-end
sales charge waivers in Investor A Shares.

BlackRock 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 period
September 29, 2006 to November 30, 2006, the following amounts have been
accrued by the Fund to reimburse BlackRock for costs incurred in running the
call center, which are a component of the transfer agent fees in the
accompanying Statements of Operations.

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


                                      11/30/2006             11/30/2005

Distributions paid from:
   Ordinary income                    $   13,499,334    $       261,509
   Net long-term capital gains                59,347                 --

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


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


Undistributed ordinary income--net                      $     3,247,982
Undistributed long-term capital gains--net                           --
                                                        ---------------
Total undistributed earnings--net                             3,247,982
Capital loss carryforward                                  (9,400,583)*
Unrealized losses--net                                    (1,602,696)**
                                                        ---------------
Total accumulated losses--net                           $   (7,755,297)
                                                        ===============

 * On November 30, 2006, the Fund had a net capital loss carryforward
   of $9,400,583, all of which expires in 2014. 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 realization for tax purposes of unrealized gains (losses)
   on certain futures contracts, the deferral of post October capital
   losses for tax purposes and other book/tax differences.

Report of Independent Registered Public Accounting Firm

                                                 BlackRock Real Investment Fund


To the Shareholders and Board of Trustees
of BlackRock Real Investment Fund:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of BlackRock Real Investment Fund
(formerly Merrill Lynch Real Investment Fund) as of November 30, 2006, and the
related statements of operations and changes in net assets and the financial
highlights for the year 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 audit. The financial statements of the Fund for the
year ended November 30, 2005 and the financial highlights for the year then
ended and for the period March 26, 2004 (commencement of operations) to
November 30, 2004, were audited by other auditors whose report, dated January
18, 2006, expressed an unqualified opinion on those financial statements and
financial highlights.

We conducted our audit 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 audit
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
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 audit provides 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 Real Investment Fund as of November 30, 2006, the results of its
operations, the changes in its net assets, and its financial highlights for
the year then ended, in conformity with accounting principles generally
accepted in the United States of America.

Notes to Financial Statements                      Master Real Investment Trust


1. Significant Accounting Policies:
Master Real Investment Trust (the "Trust") 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 non-transferable
interests in the Trust, subject to certain limitations. The Trust'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 Trust.

(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
Trust'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 Trust 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. Valuation of other 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 Trust employs pricing services to
provide certain securities prices for the Trust. 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 Trustees of
the Trust, including valuations furnished by the pricing services retained by
the Trust, which may utilize a matrix system for valuations. 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.

Equity securities held by the Trust, 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 Trustees of the Trust. 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 Trustees of the Trust.
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 Trust are determined as of
such times. 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 Trust'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 Manager using a
pricing service and/or procedures approved by the Trust's Board of Trustees.

(b) Derivative financial instruments--The Trust may engage in various
portfolio investment strategies both to increase the return of the Trust 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.

Notes to Financial Statements (continued)          Master Real Investment Trust


* Hybrid instruments--The Trust 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 Trust may purchase and write covered call and put options. When
the Trust writes an option, an amount equal to the premium received by the
Trust 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 Trust
enters into a closing transaction), the Trust 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 Trust 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 Trust deposits and maintains as collateral such initial margin
as required by the exchange on which the transaction is effected. Pursuant to
the contract, the Trust 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 Trust as
unrealized gains or losses. When the contract is closed, the Trust 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 Trust may enter into swap agreements, which are OTC contracts in
which the Trust 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 Trust 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 Trust is classified as a partnership for federal income
tax purposes. As such, each investor in the Trust is treated as owner of its
proportionate share of the net assets, income, expenses and realized and
unrealized gains and losses of the Trust. Therefore, no federal income tax
provision is required. It is intended that the Trust's assets will be managed
so an investor in the Trust 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.

(e) Securities lending--The Trust 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
Trust and any additional required collateral is delivered to the Trust on the
next business day. Where the Trust receives securities as collateral for the



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Notes to Financial Statements (continued)          Master Real Investment Trust


loaned securities, it collects a fee from the borrower. The Trust typically
receives the income on the loaned securities but does not receive the income
on the collateral. Where the Trust 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 Trust 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 Trust could
experience delays and costs in gaining access to the collateral. The Trust
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) Recent accounting pronouncements--In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes - an interpretation of FASB Statement No.
109." FIN 48 prescribes the minimum recognition threshold a tax position must
meet in connection with accounting for uncertainties in income tax positions
taken or expected to be taken by an entity including mutual funds before being
measured and recognized in the financial statements. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006. The impact on the
Trust's financial statements, if any, is currently being assessed.

In addition, 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. Management is currently evaluating
the implications of FAS 157. At this time its impact on the Trust's financial
statements has not been determined.


2. Investment Advisory Agreement and Transactions with Affiliates:
On September 29, 2006, BlackRock, Inc. and Merrill Lynch & Co., Inc. ("Merrill
Lynch") combined Merrill Lynch's investment management business, Merrill Lynch
Investment Managers, L.P. ("MLIM"), and its affiliates, with BlackRock, Inc.
to create a new independent company. Merrill Lynch has a 49.8% economic
interest and a 45% voting interest in the combined company and The PNC
Financial Services Group, Inc., has approximately a 34% economic and voting
interest. The new company operates under the BlackRock name and is governed by
a board of directors with a majority of independent members.

On August 31, 2006, shareholders of the investors in the Trust approved a new
Investment Advisory Agreement for the Trust, with BlackRock Advisors, Inc.
(the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc.
BlackRock Advisors, Inc. was recently reorganized into a limited liability
company and renamed BlackRock Advisors, LLC. The new Investment Advisory
Agreement between the Trust and the Manager became effective on September 29,
2006. Prior to September 29, 2006, MLIM was the investment adviser. The
general partner of MLIM is Princeton Services, Inc. ("PSI"), an indirect,
wholly owned subsidiary of Merrill Lynch, which is the limited partner.

The Manager is responsible for the management of the Trust's investments and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Trust. For such services, the
Trust pays a monthly fee based upon the average daily value of the Trust'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-Advisor for services it provides a fee equal
to 37% of the management fee paid by the Trust to the Manager. Prior to
September 29, 2006, MLIM had a Sub-Advisory Agreement with Merrill Lynch
Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM.

The Trust 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"), or its affiliates. Pursuant to
that order, the Trust 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. Prior to September 29, 2006, BIM was organized
as MLIM, LLC, an affiliate of MLIM, and MLIM, LLC was the Trust's securities
lending agent. BIM may, on behalf of the Trust, invest cash collateral
received by the Trust 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.

BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Report of Independent Registered Public Accounting Firm

                                                   Master Real Investment Trust


To the Investors and Board of Trustees
of Master Real Investment Trust:

We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of Master Real Investment Trust as of
November 30, 2006, and the related statement of operations, the statement of
changes in net assets, and the financial highlights for the year 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 audit. The
financial statements of the Fund for the year ended November 30, 2005 and the
financial highlights for the year then ended and for the period March 26, 2004
(commencement of operations) to November 30, 2004, were audited by other
auditors whose report, dated January 18, 2006, expressed an unqualified
opinion on those financial statements and financial highlights.

We conducted our audit 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 audit
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the
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. Our
procedures included confirmation of securities owned as of November 30, 2006,
by correspondence with the custodian and brokers; where replies were not
received from brokers, we performed other auditing procedures. We believe that
our audit provides 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 Real Investment Trust as of November 30, 2006, the results of its
operations, the changes in its net assets, and its financial highlights for
the year then ended, in conformity with accounting principles generally
accepted in the United States of America.

BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Disclosure of Investment Advisory Agreement


BlackRock Investment Advisory Agreement--Matters Considered by Each Board

The following disclosure appeared in the May 31, 2006 Semi-Annual Report of
the Fund and the Trust and is the discussion referred to in "New BlackRock Sub-
Advisory Agreements - Matters Considered by Each Board" below.

In connection with the Transaction between Merrill Lynch and BlackRock, the
Board of Trustees of Merrill Lynch Real Investment Fund and the Board of
Trustees of Master Real Investment Trust considered a new investment advisory
agreement (the "New Investment Advisory Agreement") between the Trust and
BlackRock Advisors, Inc. or its successor ("BlackRock Advisors"). If the New
Investment Advisory Agreement is approved by the Fund's shareholders, it will
become effective upon the closing of the Transaction, which is expected in the
third quarter of 2006.

The Boards discussed the New Investment Advisory Agreement at telephonic and
in-person meetings held during April and May 2006. The Boards, including the
independent trustees, approved the New Investment Advisory Agreement at a
meeting held on May 10, 2006.

To assist each Board in its consideration of the New 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 trustees, through their independent legal
counsel, also requested and received additional information from Merrill Lynch
and BlackRock in connection with their consideration of the New Investment
Advisory Agreement. The additional information was provided in advance of the
May 10, 2006 meetings. In addition, the independent trustees consulted with
their counsel and counsel for the Fund and 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 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 Investment Adviser and certain
affiliates being transferred to BlackRock in connection with the Transaction.
The independent trustees also conferred separately and with their counsel
about the Transaction 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 trustees met in executive sessions with their counsel to
consider the New Investment Advisory Agreement.

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

* that there is 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;

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

* that the Fund and Trust should 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 has no present intention to alter any applicable expense
  waivers and reimbursements currently in effect and, while it reserves 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 will 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 will continue to offer the Fund as an investment
  product;

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



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



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

* that under the Transaction Agreement, Merrill Lynch and BlackRock have 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 Investment
  Adviser (or its affiliates), respectively; and

* that Merrill Lynch and BlackRock would derive benefits from the Transaction
  and that, as a result, they have a different financial interest in the
  matters that were being considered than do 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 New Investment Advisory Agreement,
  including the fact that the schedule of the Fund's/Trust's total advisory
  fees will not increase by virtue of the New Investment Advisory Agreement,
  but will remain the same;

* that within the past year each Board performed a full annual review of the
  investment advisory agreement under which the Investment Adviser currently
  provides advisory services (the "Current Investment Advisory Agreement") as
  required by the 1940 Act, and has determined that the Investment Adviser
  has the capabilities, resources and personnel necessary to provide the
  advisory and administrative services currently 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,
  represent reasonable compensation to the Investment Adviser in light of the
  services provided, the costs to the 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 trustees have considered relevant in the exercise of
  their reasonable judgment (each Board had most recently performed a full
  annual review of the Current Investment Advisory Agreement in May 2005);
  and

* that Merrill Lynch agreed to pay all expenses of the Fund and Trust in
  connection with each Board's consideration of the New Investment Advisory
  Agreement and related agreements and all costs of shareholder approval of
  the New Investment Advisory Agreement and as a result neither the Fund nor
  Trust would bear costs in obtaining shareholder approval of the New
  Investment Advisory Agreement.

Certain of these considerations are discussed in more detail below.

In its review of the New Investment Advisory Agreement, each Board assessed
the nature, scope and quality 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 New 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 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 Trust's investment
objectives, 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.



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Disclosure of Investment Advisory Agreement (continued)


In the period prior to the Board meetings to consider renewal of the Current
Investment Advisory Agreement, each Board had requested and received materials
specifically relating to the agreement. 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 Trust's portfolio management
team on investment strategies used by the Trust during its most recent fiscal
year; (c) information on the profitability to the Investment Adviser of the
Current Investment Advisory Agreement and other payments received by the
Investment Adviser and its affiliates from the Fund and the Trust; and (d)
information provided by the Investment Adviser concerning services related to
the valuation and pricing of Trust portfolio holdings, allocation of Trust
brokerage fees, the Trust's portfolio turnover statistics, and direct and
indirect benefits to the 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 continuation of the Current Investment Advisory
Agreement, in addition to information provided by BlackRock and BlackRock
Advisors in connection with its evaluation of the terms and conditions of the
New Investment Advisory Agreement. The trustees did not identify any
particular information that was all-important or controlling, and each trustee
attributed different weights to the various factors. Each Board, including a
majority of the Board's independent trustees, concluded that the terms of the
New 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 New Investment Advisory Agreement should be approved and recommended
to Fund/Trust shareholders.

Nature, Quality and Extent of Services Provided--Each Board reviewed the
nature, extent and quality of services provided by the Investment Adviser,
including the investment advisory services and the resulting performance of
the Fund and Trust, as well as the nature, quality and extent of services
expected to be provided by BlackRock Advisors. Each Board focused primarily on
the Investment Adviser's investment advisory services and the investment
performance of the Fund and Trust, but also considered certain areas in which
both the Investment Adviser and the Fund/Trust receive services as part of the
Merrill Lynch complex. Each Board compared the performance of the Fund - both
including and excluding the effects of the Fund's 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 Investment Adviser's investment
goals, the Board will attach more importance to performance over relatively
long periods of time, typically three to five years.

In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors, each Board considered, among other things, the expected
impact of the Transaction on the operations, facilities, organization and
personnel of BlackRock Advisors 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 current investment and other
practices of the Fund or Trust. Each Board considered BlackRock's advice as to
proposed changes in portfolio management personnel of the Trust after the
closing of the Transaction.

Each Board was given information with respect to the potential benefits to the
Fund and 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 Trust will 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
were advised of the possibility of receipt of such revised regulatory relief.
There can be no assurance that such relief will be obtained.

Based on their review of the materials provided and the assurances they had
received from the management of Merrill Lynch and of BlackRock, the trustees
determined that the nature and quality of services to be provided to the Fund/
Trust under the New Investment Advisory Agreement were expected to be as good
or better than that provided under the Trust's Current Investment Advisory
Agreement. It was noted, however, that it is expected that there will be
changes in personnel following the Transaction and the combination of the
operations of the Investment Adviser and its affiliates with those of
BlackRock. Each Board noted that if current portfolio managers or other
personnel cease to be available, the Board would consider all available
options, which could include 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, extent and quality of the
services to be provided to the Fund/Trust under the New Investment Advisory
Agreement.



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Costs of Services Provided and Profitability--It was noted that, in
conjunction with the recent review of the Current Investment Advisory
Agreement, each Board had received, among other things, a report from Lipper
comparing the Fund's fees, expenses and performance to those of a peer group
selected by Lipper, and information as to the fees charged by the 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. They also compared the Fund's total expenses to those
of other comparable funds. The information showed that the Fund 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. Each Board 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 New Investment Advisory Agreement, each Board considered, among
other things, whether advisory fees or other expenses would change as a result
of the Transaction. Based on its review of the materials provided and the fact
that the New Investment Advisory Agreement is substantially similar to the
Current 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 with certainty New BlackRock's future
profitability from its relationship with the Fund and Trust.

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 Trust. Each Board noted that the Board expects
to receive profitability information from New BlackRock on at least an annual
basis and thus be in a position to evaluate whether any adjustments in 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 Trust
increase and whether there should be changes in the management fee rate or
structure in order to enable the Fund and Trust to participate in these
economies of scale. Each Board determined that changes were not currently
necessary and that the Fund and Trust appropriately participated in these
economies of scale.

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 New Investment Advisory Agreement is
substantially similar to the Current Investment Advisory Agreement in all
material respects, including the rate 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 Current Investment Advisory
Agreement. Each Board noted that in conjunction with the Board's most recent
deliberations concerning the Current Investment Advisory Agreement, the Board
had determined that the total fees for advisory and administrative services
for the Fund and Trust were reasonable in light of the services provided. It
was noted that in conjunction with the recent review of the Current Investment
Advisory Agreement, each Board had received, among other things, a report from
Lipper comparing the Fund's fees, expenses and performance to those of a peer
group selected by Lipper, and information as to the fees charged by the
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 current fee
rates, the proposed management fee structure, including any fee waivers, was
reasonable and that no additional changes were currently necessary.



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



Disclosure of Investment Advisory Agreement (concluded)


Fall-Out Benefits--In evaluating the fall-out benefits to be received by
BlackRock Advisors under the New Investment Advisory Agreement, each Board
considered whether the Transaction would have an impact on the fall-out
benefits received by the Investment Adviser by virtue of the Current
Investment Advisory Agreement. Based on their review of the materials
provided, including materials received in connection with their most recent
approval or continuance of the Current Investment Advisory Agreement, and
their discussions with management of the Investment Adviser and BlackRock, the
trustees determined that those benefits could include increased ability for
BlackRock to distribute shares of its funds and other investment products and,
where applicable, to obtain research services using the Trust's portfolio
transaction brokerage commissions. The trustees also considered possible
benefits stemming from the proposal that PFPC Financial Services, an affiliate
of BlackRock, serve as transfer agent for the Fund following the Transaction.
Each Board noted that any 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 Trust. Each Board compared the performance of the Fund and Trust -
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 FAM's investment
goals, the Board will attach more importance over relatively long periods of
time, typically three to five years. Each Board believed the Fund's and
Trust's performance was satisfactory. Also, each Board took into account the
investment performance of funds currently 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 were unable to predict what effect, if any, consummation of the
Transaction would have on the future performance of the Fund and Trust.

Conclusion--After the independent trustees of the Fund and independent
trustees of the Trust deliberated in executive session, each entire Board,
including the independent trustees, approved the New Investment Advisory
Agreement, concluding that the advisory fee rate was reasonable in relation to
the services provided and that the New Investment Advisory Agreement was in
the best interests of the shareholders. In approving the New 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.


Contingent BlackRock Sub-Advisory Agreement--Matters Considered by Each Board

At the telephonic and in-person meetings held during April and May 2006 at
which the Boards discussed and approved the New Investment Advisory Agreement,
the Trust's Board, including the independent trustees, also considered a
contingent sub-advisory agreement (the "Contingent Sub-Advisory Agreement")
between the Investment Adviser and BlackRock Advisors (the "BlackRock Sub-
Adviser"). The Contingent Sub-Advisory Agreement is intended to ensure that
the Trust operates with efficient portfolio management services until the
closing of the Transaction, in the event that each Board deems it necessary
and in the best interests of the Fund and Trust and their shareholders that
the BlackRock Sub-Adviser assist in managing the operations of the Trust
during the interim period until the closing of the Transaction. If
shareholders approve the Contingent Sub-Advisory Agreement, it will take
effect only upon recommendation from the Investment Adviser and upon
subsequent approval of each Board in the period up to the closing of the
Transaction. The effectiveness of the Contingent Sub-Advisory Agreement,
therefore, would be contingent on further Board approval after shareholders
approve it. Pursuant to the Contingent Sub-Advisory Agreement, the BlackRock
Sub-Adviser would receive a monthly fee from the Investment Adviser equal to
50% of the advisory fee received by the Investment Adviser. The Investment
Adviser would pay the BlackRock Sub-Adviser out of its own resources. There
would be no increase in Fund or Trust expenses as a result of the Contingent
Sub-Advisory Agreement.



BLACKROCK REAL INVESTMENT FUND                                NOVEMBER 30, 2006



In making its approval at the May in-person meeting, each Board considered the
Contingent Sub-Advisory Agreement in conjunction with the New Investment
Advisory Agreement and reviewed the same information and factors discussed
above. Each Board also considered in conjunction with the Contingent Sub-
Advisory Agreement the necessity of ensuring that the Trust operates with
effective management services until the closing of the Transaction. In
reviewing the sub-advisory fee rate provided in the Contingent Sub-Advisory
Agreement, each Board took note of the fact that both the Investment Adviser
and the BlackRock Sub-Adviser would have significant responsibilities under
their respective advisory agreements. The Investment Adviser would remain
responsible for oversight of the operations and administration of the Fund and
Trust, and the BlackRock Sub-Adviser would provide advisory services to the
Trust under the Contingent Sub-Advisory Agreement. Each Board also took into
account the expected short duration of the term of any Contingent Sub-Advisory
Agreement and the fact that total advisory fees paid by the Fund and Trust
would not increase as a result of the Contingent Sub-Advisory Agreement. Under
all of the circumstances, each Board concluded that it was a reasonable
allocation of fees for the BlackRock Sub-Adviser to receive 50% of the
advisory fee paid by the Trust to the Investment Adviser.

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




Disclosure of Sub-Advisory Agreement


New BlackRock Sub-Advisory Agreements--Matters Considered by Each Board

At an in-person meeting held on August 24 - 25, 2006, the Board of the Fund
and the Board of the Trust, including the independent trustees, discussed and
approved the sub-advisory agreements between BlackRock Advisors and each of
BlackRock Financial Management, Inc. and BlackRock Investment Management, LLC,
each an affiliate (the "Sub-Advisers") (the "BlackRock Sub-Advisory
Agreements"). The BlackRock Sub-Advisory Agreements became effective on
September 29, 2006, at the same time the New Investment Advisory Agreement
with BlackRock Advisors (which had been approved by the Fund's shareholders)
became effective.

Pursuant to the pertinent BlackRock Sub-Advisory Agreement, each Sub-Adviser
receives a monthly fee from BlackRock Advisors equal to 37% of the advisory
fee received by BlackRock Advisors from 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 the BlackRock Sub-Advisory Agreements at the August in-person
meeting, the Boards reviewed their considerations in connection with their
approval of the New Investment Advisory Agreement 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 New Investment Advisory
Agreement. In reviewing the sub-advisory fee rate provided for in the
BlackRock Sub-Advisory Agreements, the Boards noted the fact that both
BlackRock Advisors and each Sub-Adviser have significant responsibilities
under their respective advisory agreements. Under the New Investment Advisory
Agreement, BlackRock Advisors remains responsible for the overall management
of the Fund and the Trust and for oversight of the Fund's and the Trust's
operations and administration. Under each BlackRock Sub-Advisory Agreement,
each Sub-Adviser provides advisory services to the Trust and is responsible
for the day-to-day management of the Trust's portfolio. 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.
Based on its considerations, each Board concluded that it was a reasonable
allocation of fees for each Sub-Adviser to receive 37% of the advisory fee
paid by the Trust to BlackRock Advisors.

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

Item 2 -   Code of Ethics - The registrant has adopted a code of ethics, as of
           the end of the period covered by this report, that applies to the
           registrant's principal executive officer, principal financial
           officer and principal accounting officer, or persons performing
           similar functions.  A copy of the code of ethics is available
           without charge at www.blackrock.com.

Item 3 -   Audit Committee Financial Expert - The registrant's board of
           directors has determined that (i) the registrant has the following
           audit committee financial experts serving on its audit committee and
           (ii) each audit committee financial expert is independent: (1) David
           O. Beim, (2) W. Carl Kester, (3) James T. Flynn and (4) Karen P.
           Robards.

           The registrant's board of directors has determined that David O.
           Beim, W. Carl Kester and Karen P. Robards qualify as financial
           experts pursuant to Item 3(c)(4) of Form N-CSR.

           Mr. Beim has a thorough understanding of generally accepted
           accounting principles, financial statements and internal control
           over financial reporting as well as audit committee functions.  For
           25 years, Mr. Beim was an investment banker actively engaged in
           financial analysis for securities transactions and mergers.  These
           transactions presented a breadth and level of complexity of
           accounting issues that are generally comparable to the breadth and
           complexity of issues that can reasonably be expected to be raised by
           the Registrant's financial statements.  Mr. Beim has also been a
           professor of finance and economics at the Columbia University
           Graduate School of Business for the past 13 years.

           Prof. Kester has a thorough understanding of generally accepted
           accounting principles, financial statements and internal control
           over financial reporting as well as audit committee functions.
           Prof. Kester has been involved in providing valuation and other
           financial consulting services to corporate clients since 1978.
           Prof. Kester's financial consulting services present a breadth and
           level of complexity of accounting issues that are generally
           comparable to the breadth and complexity of issues that can
           reasonably be expected to be raised by the Registrant's financial
           statements.

           Ms. Robards has a thorough understanding of generally accepted
           accounting principles, financial statements and internal control
           over financial reporting as well as audit committee functions.  Ms.
           Robards has been President of Robards & Company, a financial
           advisory firm, since 1987.  Ms. Robards was formerly an investment
           banker for more than 10 years where she was responsible for
           evaluating and assessing the performance of companies based on their
           financial results.  Ms. Robards has over 30 years of experience
           analyzing financial statements.  She also is the member of the Audit
           Committees of two privately held companies and a non-profit
           organization.

           (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.

               Fiscal Year Ending November 30, 2005 - $5,700

           (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.

Item 11 -  Controls and Procedures

11(a) -    The registrant's certifying officers have reasonably designed such
           disclosure controls and procedures to ensure material information
           relating to the registrant is made known to us by others
           particularly during the period in which this report is being
           prepared.  The registrant's certifying officers have determined that
           the registrant's disclosure controls and procedures are effective
           based on our evaluation of these controls and procedures as of a
           date within 90 days prior to the filing date of this report.

11(b) -    As of September 29, 2006, with the conclusion of the combination of
           Merrill Lynch's asset management business with BlackRock, the
           registrant was migrated to BlackRock's trading and compliance
           monitoring systems, and various personnel changes occurred.  In
           conjunction with these business improvements, there were no changes
           in the registrants internal control over financial reporting (as
           defined in Rule 30a-3(d) under Act (17 CFR 270.30a-3(d)) that
           occurred during the last fiscal half-year of the period covered by
           this report that has materially affected, or is reasonably likely to
           affect, the registrant's internal control over financial reporting.
