A Letter to Shareholders


Dear Shareholder

The new year began on a positive note for most financial markets, continuing
the momentum from the fourth quarter of 2006. At the end of February, however,
global equity markets registered their first significant decline since last
summer. The market jitters were triggered by a significant setback in the
Chinese market and were exacerbated by several concerns, notably a weakening
economy, some disappointing corporate earnings announcements, geopolitical
concerns related to Iran's nuclear program and increasing delinquencies in the
subprime mortgage market. Despite the recent spate of volatility, underlying
stock market fundamentals appear quite sound, supported by a generally good
global economic backdrop, tame inflation, relatively low interest rates and
attractive valuations.

Not unlike the equity market, the bond market also has seen volatility
recently as observers have attempted to interpret mixed economic signals. A
bond market rally late last year reversed early in 2007 as the economic data
strengthened. Prices improved (and yields fell) again in February as equities
struggled. Notably, the Treasury curve remained inverted for much of 2006 and
into 2007. The 30-year Treasury yield stood at 4.68% on February 28, 2007,
while the one-month Treasury offered the highest yield on the curve at 5.24%.

For its part, the Federal Reserve Board (the Fed) has left the target short-
term interest rate on hold at 5.25% since first pausing on August 8, 2006.
Although the central bankers continue to express concern about potential
inflationary pressures, they also have made reference to signs of economic
weakness in their public statements. Most observers expect the Fed to keep
interest rates on hold for now, but acknowledge that the combination of a mild
economic slowdown and moderating inflation could prompt an interest rate cut
later in 2007.

Notwithstanding the volatility along the way, most major market indexes
managed to post positive returns for the annual and semi-annual reporting
periods ended February 28, 2007:

If the recent market movements are any guide, 2007 could be a year of enhanced
market volatility. As you navigate the uncertainties of the financial markets,
we encourage you to review your investment goals with your financial
professional and to make portfolio changes, as needed. We thank you for
trusting BlackRock with your investment assets, and we look forward to
continuing to serve you in the months and years ahead.

A Discussion With Your Fund's Portfolio Manager


The Fund continued to meet its primary objective of preserving investor
principal during the semi-annual reporting period.


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

For the six-month period ended February 28, 2007, BlackRock Fundamental Growth
Principal Protected Fund's Institutional, Investor A, Investor B and Investor
C Shares had total returns of +1.58%, +1.58%, +1.20% and +1.09%, respectively.
For the same period, the Fund's all-equity benchmark, the S&P 500 Citigroup
Growth Index, returned +7.18%, while the broader U.S. equity market, as
measured by the S&P 500 Index, gained 8.93%. (Fund results shown do not
reflect sales charges and would be lower if sales charges were included.
Complete performance information can be found on pages 6 and 7 of this report
to shareholders.) The Lipper category of Mixed-Asset Target Allocation Growth
Funds posted an average return of +7.56% for the six-month period. (By
portfolio practice, funds in this Lipper category maintain a mix of 60% - 80%
equity securities, with the remainder invested in bonds, cash and cash
equivalents.)

The Fund incorporates a fixed income component and, therefore, its returns
will necessarily differ from those of the equity markets alone. The fixed
income market, as measured by the Lehman Brothers Aggregate Bond Index,
returned +3.66% for the six-month period. Given the comparatively strong
performance of the equity markets, the fixed income component hindered the
Fund's results. Likewise, the positioning of the equity portfolio detracted
from performance in what was a challenging period for the large cap growth
style of investing.

During the six-month reporting period, small- and mid-sized companies led the
market out of the bottom that had been reached in mid-July 2006. In addition,
a general bias toward value investing continued to dominate throughout the
period. Concerns about the direction and magnitude of growth in the U.S.
economy also significantly influenced market leadership, as a clear defensive
tone emerged with renewed investor interest in "mega caps" (that is, the
largest companies as measured by market cap) evident across most sectors. This
tended to favor market-capitalization-weighted indexes over individual growth
stock selection. Furthermore, investor perceptions and definitions of growth
and value became increasingly ambiguous against this backdrop. The new year
opened with equity markets performing strongly until the end of February, when
investor concerns over global risk premiums once again sent global equity
markets into a corrective phase.

The performance of the Fund's equity portfolio was negatively influenced by
our conviction that growth stocks were attractive investments, while the
market, in general, had become more defensive. Consequently, the Fund's
underperformance versus the largely market-weighted benchmark resulted from an
underrepresentation in "mega cap" stocks, in addition to adverse security
selection. In particular, we saw poor performance among portfolio holdings in
the consumer discretionary, health care and information technology sectors.
Conversely, stock selection in the materials and financials sectors was
modestly favorable, as were the Fund's underweight positions in consumer
staples and health care. The Fund's relative performance improved measurably
by the end of the period (specifically, year-to-date through February), as our
positioning gained investor acceptance.

Individual Fund holdings that detracted from performance during the six-month
period included Medco Health Solutions, Inc., CVS Corp., WellPoint, Inc.,
Motorola, Inc. and Corning, Inc. At the same time, several names were notably
additive to performance, including Cognizant Technology Solutions Corp.,
Infosys Technologies Ltd., Nike, Inc., Pall Corp. and Nalco Holding Co.
Avoidance of Pfizer, Inc. and Johnson & Johnson aided relative performance,
while lack of exposure to Microsoft Corp. detracted.


What changes were made to the portfolio during the period?

A mathematical formula is used to determine the allocation between the Fund's
equity and fixed income components. During the six-month period, the Fund's
equity component ranged from a high of 68.1% of net assets to a low of 55.6%,
while the fixed income allocation ranged from as much as 44.4% of net assets
to 31.9%. The Fund's fixed income component was invested in U.S. Treasury zero-
coupon bonds set to mature close to the expiration of the Fund, which is seven
years from its commencement of operations (November 13, 2009).



BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND         FEBRUARY 28, 2007



We made strides in repositioning the equity portfolio after the mid-2006
market correction to adjust to a more moderate rate of economic growth in the
United States and shifts in sector leadership. To that end, we reduced our
overweight position in energy to a slight underweight, while increasing our
position in information technology from an underweight to a modest overweight.
We also trimmed the portfolio's overweighting in industrials and exited the
managed-care industry, thereby reducing overall exposure to the health care
sector. Finally, we increased the portfolio's positions in the consumer
discretionary and financials sectors, particularly in retail and capital
markets-related companies, respectively.

In terms of individual stocks, significant additions included Coach Inc.,
Thermo Fisher Scientific, Inc., Target Corp., EMC Corp., The Goldman Sachs
Group, Inc., American International Group, Inc., Oracle Corp. and Comcast
Corp. Significant sales or reductions included WellPoint, Inc., Altria Group,
Inc., Exxon Mobil Corp. (which we sold and repurchased within the period),
Bank of America Corp., Medco Health Solutions, Inc., CVS Corp., The Procter &
Gamble Co., Valero Energy Corp., Alcon, Inc., GlaxoSmithKline Plc and Amgen,
Inc.


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

In seeking to meet its objective of principal protection and potential for
capital growth, the allocation between the Fund's fixed income and equity
components will continue to vary as market conditions change. As of February
28, 2007, the Fund was invested 57.8% in equities and 42.2% in fixed income
securities. This compared to 58.8% equities and 41.2% fixed income at August
31, 2006.

U.S. economic growth (that is, gross domestic product growth) has slowed to a
slightly below-trend rate of expansion (in the area of 2% - 3%). We view this
as a typical mid-cycle slowdown and do not expect a recession to unfold. In
fact, we suspect there is upside risk to accelerating economic growth in the
United States by year-end 2007. At this time, it appears as if inflation
expectations have been well-contained via adequate Federal Reserve Board
policy initiatives. While most other global economies, particularly those in
Europe and Asia, continue to experience strong rates of growth, we are
reviewing portfolio positioning in light of apparent changes recently (late
February) in market risk parameters. Although this mid-cycle slowdown may
challenge broader market (S&P 500 Index) earnings growth over the near term,
we believe it should provide an attractive investment environment for select
growth stocks going forward.

At the end of the period, the Fund's equity portfolio was overweight relative
to its benchmark in the consumer discretionary, information technology and
materials sectors, and had significant underweights in consumer staples and
health care.

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 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.

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 September 1, 2006 and
held through February 28, 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
   (1.82% for Institutional, 2.07% for Investor A, 2.83% for Investor B and 2.83% for Investor C),
   multiplied by the average account value over the period, multiplied by 181/365 (to reflect the
   one-half year period shown).

** 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 FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND         FEBRUARY 28, 2007



Notes to Financial Statements (Unaudited)


1. Significant Accounting Policies:
BlackRock Fundamental Growth Principal Protected Fund (the "Fund") is part of
BlackRock Principal Protected Trust (the "Trust"). The Fund is a separate
diversified series of the Trust, which is registered as an open-end management
investment company under the Investment Company Act of 1940, as amended. 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
for the interim period. All such adjustments are of a normal, recurring
nature. The Fund offers multiple classes of shares. Shares of the Fund were
offered during the initial offering period but will not be offered during the
Guarantee Period from November 13, 2002 through November 13, 2009 (the
"Guarantee Maturity Date"), except in connection with reinvestment of
dividends and distributions. The Fund will be offered on a continuous basis
after the Guarantee Maturity Date without the principal protection feature.
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
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--Equity securities held by the Fund that are
traded on stock exchanges or the NASDAQ Global Market are valued at the last
sale price or official close price on the exchange, as of the close of
business on the day the securities are being valued or, lacking any sales, at
the last available bid price for long positions, and at the last available
asked price for short positions. In cases where equity securities are traded
on more than one exchange, the securities are valued on the exchange
designated as the primary market by or under the authority of the Board of
Trustees of the Fund. Long positions traded in the over-the-counter ("OTC")
market, NASDAQ Capital Market or Bulletin Board are valued at the last
available bid price or yield equivalent obtained from one or more dealers or
pricing services approved by the Board of Trustees of the Fund. Short
positions traded in the OTC market are valued at the last available asked
price. Portfolio securities that are traded both in the OTC market and on a
stock exchange are valued according to the broadest and most representative
market.

Options written or purchased are valued at the last sale price in the case of
exchange-traded options. Options traded in the OTC market 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 Fund from a pricing service or counterparty. Financial futures contracts
and options thereon, which are traded on exchanges, are valued at their last
sale price as of the close of such exchanges. Obligations with remaining
maturities of 60 days or less are valued at amortized cost unless BlackRock
Advisors, LLC (the "Manager"), an indirect, wholly owned subsidiary of
BlackRock, Inc., believes that this method no longer produces fair valuations.
Valuation of other short-term investment vehicles is generally based on the
net asset value of the underlying investment vehicle or amortized cost.

Repurchase agreements are valued at cost plus accrued interest. The Fund
employs pricing services to provide certain securities prices for the Fund.
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 Fund, including valuations furnished by the
pricing services retained by the Fund, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are
reviewed by the officers of the Fund under the general supervision of the
Fund's Board of Trustees. Such valuations and procedures will be reviewed
periodically by the Board of Trustees of the Fund.

Notes to Financial Statements (continued)


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 asset value of the Fund's shares 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 Fund's net asset
value. 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 will be valued at their
fair value as determined in good faith by the Fund's Board of Trustees or by
the Manager using a pricing service and/or procedures approved by the Fund's
Board of Trustees.

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

* Financial futures contracts--The Fund 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 Fund deposits and maintains as collateral such initial margin as required
by the exchange on which the transaction is effected. Pursuant to the
contract, the Fund 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 Fund as
unrealized gains or losses. When the contract is closed, the Fund records a
realized gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.

* Options--The Fund may write and purchase call and put options. When the Fund
writes an option, an amount equal to the premium received by the Fund is
reflected as an asset and an equivalent liability. The amount of the liability
is subsequently marked-to-market to reflect the current 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 Fund enters into a
closing transaction), the Fund 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.

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

(d) Income taxes--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. Under the applicable
foreign tax law, a withholding tax may be imposed on interest, dividends and
capital gains at various rates.



BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND         FEBRUARY 28, 2007



Notes to Financial Statements (continued)


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

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

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.

(f) 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.
Dividends from foreign securities where the ex-dividend date may have passed
are subsequently recorded when the Fund has determined the ex-dividend date.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

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

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


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. ("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.



BLACKROCK FUNDAMENTAL GROWTH PRINCIPAL PROTECTED FUND         FEBRUARY 28, 2007



Notes to Financial Statements (continued)


The Investment Advisory Agreement between the Fund and the Manager became
effective on September 29, 2006. Prior to September 29, 2006, MLIM was the
Fund's manager. The general partner of MLIM is Princeton Services, Inc.
("PSI"), an indirect, wholly owned subsidiary of Merrill Lynch, which is the
limited partner. 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.

The Manager is responsible for the management of the Fund's portfolio and
provides the necessary personnel, facilities, equipment and certain other
services necessary to the operations of the Fund. For such services, the Fund
pays a monthly fee at the annual rate of .65% of the Fund's average daily net
assets. The Manager has entered into a contractual arrangement with the Fund
under which the expenses incurred by each class of shares of the Fund
(excluding distribution and/or service fees) will not exceed 1.99%. This
arrangement has a one-year term and is automatically renewable.

In addition, the Manager has entered into a sub-advisory agreement with
BlackRock Investment Management, LLC ("BIM"), an affiliate of the Manager,
under which the Manager pays BIM for services it provides a monthly fee at an
annual rate that is a percentage of the management fee paid by the Fund to the
Manager.

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 each Distributor
ongoing service and distribution fees. The fees are accrued daily and paid
monthly at annual rates based upon the average daily net assets of the 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 each Distributor provide shareholder
servicing and distribution services to the Fund. The ongoing service fee
compensates the Distributor and each broker-dealer (including MLPF&S) for
providing shareholder services to Investor A, Investor B and Investor C
shareholders. The ongoing distribution fee compensates each Distributor and
MLPF&S for providing shareholder servicing and distribution-related services
to Investor B and Investor C shareholders.

For the six months ended February 28, 2007, MLPF&S received contingent
deferred sales charges of $73,374 and $50 relating to transactions in Investor
B and Investor C Shares, respectively.

The Trust, on behalf of the Fund, has entered into a Financial Warranty
Agreement with Main Place Funding, LLC (the "Warranty Provider"). The
Financial Warranty Agreement is intended to ensure that on the Guarantee
Maturity Date, each shareholder of the Fund will be entitled to redeem his or
her shares for an amount no less than the initial value of that shareholder's
account (less expenses and sales charges not covered by the Financial Warranty
Agreement), provided that all dividends and distributions received from the
Fund have been reinvested and no shares have been redeemed (the "Guaranteed
Amount"). The Fund will pay to the Warranty Provider, under the Financial
Warranty Agreement, an annual fee equal to .80% of the Fund's average daily
net assets during the Guarantee Period. If the value of the Fund's assets on
the Guarantee Maturity Date is insufficient to result in the value of each
shareholder's account being at least equal to the share-holder's Guaranteed
Amount, the Warranty Provider will pay the Fund an amount sufficient to ensure
that each shareholder's account can be redeemed for an amount equal to his or
her Guaranteed Amount.

The Manager maintains a call center, which is responsible for providing
certain shareholder services to the Fund, such as responding to shareholder
inquiries and processing transactions based upon instructions from
shareholders with respect to the subscription and redemption of Fund shares.
During the period September 29, 2006 to February 28, 2007, the following
amounts have been accrued by the Fund to reimburse the Manager for costs
incurred running the call center, which are a component of the transfer agent
fees in the accompanying Statement of Operations.

Investor C                                      $242


The Fund has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to MLPF&S or its
affiliates. Pursuant to that order, the Fund has retained BIM 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 Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of MLIM,
and MLIM, LLC was the securities lending agent. BIM may, on behalf of the
Fund, invest cash collateral received by the Fund for such loans, among other
things, in a private investment company managed by the Manager or its
affiliates.

In addition, MLPF&S received $12,123 in commissions on the execution of
portfolio security transactions for the Fund for the six months ended February
28, 2007.

For the six months ended February 28, 2007, the Fund reimbursed MLIM and the
Manager $181 and $904, respectively, for certain accounting services.

Effective September 29, 2006, PFPC Inc., an indirect, wholly owned subsidiary
of PNC and an affiliate of the Manager, became the Fund's transfer agent.
Prior to September 29, 2006, the Fund's transfer agent was Financial Data
Services, Inc. ("FDS"), a wholly owned subsidiary of Merrill Lynch.

Prior to September 29, 2006, certain officers and/or trustees of the Fund
were officers and/or directors of MLIM, PSI, FDS, FAMD, Merrill Lynch, and/or
MLIM, LLC.

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


3. Investments:
Purchases and sales of investments, excluding short-term securities, for the
six months ended February 28, 2007 were $46,031,498 and $65,405,228,
respectively.


4. Beneficial Interest Transactions:
Net decrease in net assets derived from beneficial interest transactions was
$12,164,790 and $34,010,687 for the six months ended February 28, 2007 and the
year ended August 31, 2006, respectively.

Transactions in beneficial interest for each class were as follows:

 * In September 2006, certain brokerages, including a wholly owned
   subsidiary of Merrill Lynch, entered into a remediation agreement
   with a regulatory organization, which among other things, permitted
   certain shareholders of Investor B Shares to convert their shares
   into the Fund's Investor A Shares.


5. Short-Term Borrowings:
The Fund, 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 Fund may borrow under the credit agreement to fund shareholder
redemptions and for other lawful purposes other than for leverage. The Fund
may borrow up to the maximum amount allowable under the Fund'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
Fund pays a commitment fee of .06% per annum based on the Fund'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 Fund did not borrow under the credit agreement during
the six months ended February 28, 2007.
