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, 2006. This left the federal funds rate at 5.25%, where it remained through
year-end. In interrupting its two-year interest rate-hiking campaign, the Fed
acknowledged that economic growth is slowing, led by a downturn in the housing
market, but has maintained a cautionary view on inflation.

Overall, it was a good 12 months for U.S. equities, despite a significant
correction in the middle of the year that was largely triggered by rising
interest rates, inflation fears, elevated oil prices and geopolitical
uncertainties. Nevertheless, strong corporate earnings, abundant liquidity and
record merger-and-acquisition activity provided a solid backdrop for stocks.
Many international equity markets (with the notable exception of Japan)
performed even better, outpacing U.S. stocks for the fifth consecutive year.
Strength was especially notable in European equities and select emerging
markets.

Bonds experienced a more modest annual return than stocks. Interest rates and
bond yields moved higher for much of the year as bond prices, which move
opposite of yields, declined. Prices began to improve in the summer as the
economy showed signs of weakening and the Fed paused. Notably, the Treasury
curve remained inverted for much of 2006. The 10-year Treasury yield ended
December at 4.71%, well below the federal funds rate.

As we begin a new year, investors are left with a few key questions: Will the
U.S. economy achieve a soft landing, will the Fed reverse its prior policy and
cut interest rates, and how might these outcomes impact the investment climate.
As you navigate the uncertainties inherent in the financial markets, we
encourage you to start the year by reviewing your investment goals with your
financial professional and making portfolio changes, as needed. For more
reflection on 2006 and our thoughts on the year ahead, please ask your financial
professional for a copy of "What's Ahead in 2007: An Investment Perspective," or
view it online at www.blackrock.com/funds. We thank you for trusting BlackRock
with your investment assets, and we look forward to continuing to serve you in
the new year and beyond.

                                                Sincerely,


                                                /s/ Robert C. Doll, Jr.

                                                Robert C. Doll, Jr.

       BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006      3


A Discussion With Your Fund's Portfolio Manager

      With its equity allocation at 100% of net assets throughout the period,
the Fund was successfully able to meet its primary objective of preserving
investor principal while also providing solid capital appreciation for
shareholders.

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

For the six-month period ended December 31, 2006, BlackRock Basic Value
Principal Protected Fund's (formerly Merrill Lynch Basic Value Principal
Protected Fund) Institutional, Investor A, Investor B and Investor C Shares had
total returns of +15.44%, +15.27%, +14.82% and +14.78%, 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.)

The Fund outperformed the +12.74% return of the Standard & Poor's 500 (S&P 500)
Index, the +13.40% return of the S&P 500 Citigroup Value Index and the +9.29%
average return of the Lipper Mixed-Asset Target Allocation Growth Funds
category. (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.) Throughout the six-month period, the Fund's equity allocation
remained at 100% of net assets. Accordingly, the fixed income allocation was 0%.
This proved advantageous as stocks significantly outperformed bonds, as measured
by the +5.09% return of the Lehman Brothers Aggregate Bond Index.

As the six-month period began, the market was recovering from a far-reaching
correction that sent the average U.S. stock 12% lower. It was the first
double-digit correction for U.S. equity markets in nearly four years. Areas of
the market that had suffered most were those that had done the best in the
preceding few years, particularly materials and energy stocks. The pullback
could be attributed to several factors, but primarily, it appeared that the
lagged effects of higher interest rates and oil prices were finally taking their
toll on the economy and stock prices. In addition, a resurgence of inflation
fears had prompted the Federal Reserve Board (the Fed) to continue its interest
rate tightening campaign through June.

In August, the Fed finally ended its two-year streak of interest rate increases.
Oil prices, after reaching an all-time high near $78 per barrel in July, also
began to recede and ended the year where they started -- at $61 per barrel.
Stocks generally climbed back above the levels they reached prior to the
market's retrenchment. Once the bottom was hit, a different collection of
companies started to outperform those that had been the market leaders. From
June to year-end, it was large cap, multinational companies that dominated the
market. Valuations on these big names had become incredibly attractive from a
risk-reward standpoint, prompting us to increase our exposure. This move proved
advantageous, as many of our top performers during the six-month period were
just those types of companies: International Business Machines Corp. (with a
market capitalization of $150 billion), Morgan Stanley ($85 billion), Exxon
Mobil Corp. ($420 billion), Comcast Corp. ($90 billion), McDonald's Corp. ($55
billion), Unilever NV ($45 billion) and Time Warner, Inc. ($90 billion).

For the most part, Fund performance during the period was driven by favorable
security selection. However, from a sector perspective, we saw very strong
results in industrials, led by defense company Raytheon Co. and another
safehaven, General Electric Co. Both of these stocks began to perform
particularly well at the end of the year as investors started rotating into
large, stable companies that could offer consistent earnings. Other stocks that
contributed meaningfully to relative performance were Baxter International, Inc.
in health care, and Interpublic Group of Cos., Inc. in consumer discretionary.

What changes were made to the portfolio during the period?

The Fund seeks long-term capital growth while protecting the principal value of
investor shares. This is accomplished through investments in a core equity
component for growth and a fixed income component for an element of protection.
A mathematical formula is used to determine the allocation between these two
components. Throughout the period, the portfolio remained fully invested in
equities.

Within the equity portfolio, we increased our emphasis on large-cap,
multinational names, but still maintained exposure to some of the smaller,
cyclically oriented sectors and names that we believe continue to have
tremendous potential. While the economy has slowed somewhat, it remains
reasonably resilient and should continue to benefit these types of companies. We
view the current economic environment as a "Goldilocks" scenario (not too hot,
not too cold). As such, we believe it makes sense to have representation in the
more stable names that can benefit in a "not too hot" environment as well as the
smaller, high-growth potential companies that can perform well under a "not too
cold" scenario.

In general, we continued to de-emphasize the energy sector as profit-taking
opportunities became available. We had been overweight in energy from the middle
of 2002 through the summer of 2005, when Hurricane Katrina ravaged the Gulf
Coast. Around that time, we began to move our energy exposure toward neutral in
anticipation of a slowing economy and the resultant fall off in demand for oil
and gas. We continue to see select opportunities in energy, but as value
investors, we believe other areas of the market offer more attractive valuations
and compelling growth prospects.

One such area is health care. During the past year, we added positions in
Johnson & Johnson, Pfizer, Inc., Schering-Plough Corp., Baxter International and
GlaxoSmithKline Plc. Last year was the first since the mid-1990s that we have
been overweight in health care, a reflection of the attractive fundamentals in
this industry group. In prior years, the health care industry has had to grapple
with a lack of new blockbuster products to offset drug patent expirations and
government pressures on pharmaceutical pricing, among other issues. It offered
little value compared to other sectors of the market. This is no longer the
case, as valuations are very appealing and company managements are taking steps
to control costs via restructuring and cost-saving initiatives. In addition,
earnings estimates for pharmaceutical companies are increasing for the first
time in a long time.

Another sector we continue to favor is information technology (IT). Earnings
estimates for the first half of 2007 indicate that IT is expected to be the
fastest-growing sector in the S&P 500. Whereas earnings estimates for energy
companies are down for the first half of the year, IT estimates are up
double-digit percentages. We have seen more disinvestment than investment in IT
companies since the post-Y2K bubble. However, with productivity figures and the
economy slowing somewhat for the first time in several years, we think that
spending on technology will increase. Arguably, there is no better avenue for
the advancement of worker productivity than through IT. Other notable happenings
in the IT industry include a new product cycle from Microsoft Corp. (that is,
Vista), as well as some exciting innovations in home entertainment, including
flat panel technology, high-definition TV and PC on TV. In keeping with our
favorable view of the sector, we increased exposure to Intel Corp., Motorola,
Inc. and Sony Corp. during the six-month period ended December 31, 2006.

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

As of December 31, 2006, the portfolio remained 100% invested in equities.
Compared to the S&P 500 Citigroup Value Index, the Fund ended the period
overweight in energy, consumer staples, IT, health care and consumer
discretionary. It had underweight positions in financials, utilities,
industrials, materials and telecommunication services.

The equity market enjoyed a very healthy end-of-year rally. We believe the Fed's
policy, to date, has struck the proper balance of fending off inflation while
allowing the economic recovery to continue at a healthy pace. A favorable
economic backdrop has led to healthy corporate profits, strong corporate balance
sheets and robust merger-and-acquisition (M&A) activity. We believe these
factors should remain in place, but are mindful that weakness in the housing
market could lead to a slower rate of growth for the economy in the future.
Against this backdrop, we continue to find that large-capitalization companies
offer a more compelling value proposition as we enter a potentially slower phase
of the economic recovery.

Overall, we do not expect the first half of 2007 to be very different from the
second half of 2006 and will continue to focus on companies with healthy balance
sheets and the ability to use free cash flow to buy back stock, raise dividends,
participate in M&A activity and invest in their businesses. We will pursue this
within the context of our value-oriented investment style, choosing companies
that we believe have the potential to offer shareholders significant value over
a three-year time horizon.

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:

o     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.

o     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).

o     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.)

o     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 July 1, 2006 and held through
December 31, 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.

      ratio for the class (1.69% for Institutional, 1.94% for Investor A, 2.70%
      for Investor B and 2.70% for Investor C), multiplied by the average
      account value over the period, multiplied by 182/365 (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 BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006     15


Notes to Financial Statements

1. Significant Accounting Policies:

Effective September 29, 2006, Merrill Lynch Basic Value Principal Protected Fund
(the "ML Fund") and Merrill Lynch Principal Protected Trust, which the ML Fund
is part of, were renamed BlackRock Basic Value Principal Protected Fund (the
"Fund") and BlackRock Principal Protected Trust (the "Trust"), respectively.
Under the Investment Company Act of 1940, as amended, the Fund is diversified
and the Trust is registered as an open-end management investment company. 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. 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. 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 this date. During the Guarantee
Period, the Fund will seek long-term growth of capital to the extent permitted
by a strategy that seeks to use investments in common stocks, U.S. Treasury
bonds, including zero coupon bonds, and other fixed income instruments, to
protect the original principal value of the Fund (less redemptions, cash
distributions and dividends and extraordinary expenses) at the Guarantee
Maturity Date.

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 make sure 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 shareholder's Guaranteed Amount, the Warranty Provider
will pay the Fund an amount sufficient to make sure that each shareholder's
account can be redeemed for an amount equal to his or her Guaranteed Amount.

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 -- Equity securities that are 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 Trust.
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 Trust. Short positions traded in the OTC market are
valued at the last available asked price. Portfolio securities that are traded
both in the OTC market and on a stock exchange are valued according to the
broadest and most representative market.

Debt securities are traded primarily in the OTC markets and are valued at the
last available bid price in the OTC market or on the basis of values obtained by
a pricing service. Pricing services use valuation matrixes that incorporate both
dealer-supplied valuations and valuation models. The procedures of the pricing
service and its valuations are reviewed by the officers of the Fund under the
general direction of the Board


16     BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006


Notes to Financial Statements (continued)

of Trustees. Such valuations and procedures will be reviewed periodically by the
Board of Trustees.

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 Trust
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 Trust, including valuations furnished by the
pricing services retained by the Trust, which may use a matrix system for
valuations. The procedures of a pricing service and its valuations are reviewed
by the officers of the Trust under the general supervision of the Trust's Board
of Trustees. Such valuations and procedures will be reviewed periodically by the
Board of Trustees of the Trust.

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
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 Fund may engage in various portfolio
investment 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 or if the
counterparty does not perform under the contract.

o     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.

o     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


       BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006     17


Notes to Financial Statements (continued)

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.

(e) 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.

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

(g) 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.

(h) Bank overdraft -- The Fund recorded a bank overdraft, which resulted from
management estimates of available cash.

(i) 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 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.

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, including Fund Asset
Management, L.P. ("FAM"), 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 15, 2006, shareholders of the Fund approved a new Investment Advisory
Agreement with the Manager.


18     BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006


Notes to Financial Statements (continued)

BlackRock Advisors, Inc. was recently reorganized into a limited liability
company and renamed BlackRock Advisors, LLC. The new Investment Advisory
Agreement between the Fund and the Manager became effective on September 29,
2006. Prior to September 29, 2006, FAM was the Fund's Investment Adviser. The
general partner of FAM 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 account maintenance fees ("service fees")) will not exceed
1.99%. This arrangement has a one-year term and is 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 the Sub-Advisor for services it provides a monthly fee
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 the 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:

Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), a wholly owned
subsidiary of Merrill Lynch, and an affiliate of the Distributor, provides
account maintenance and distribution services to the Fund. The ongoing service
fee compensates the Distributor 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 Distributor and the
broker-dealers for providing shareholder and distribution-related services to
Investor B and Investor C shareholders.

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 in registered money market funds

Manager $887 and $887, respectively, for certain accounting services.

20     BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006


Disclosure of Investment Advisory Agreement

BlackRock Investment Advisory Agreement -- Matters Considered by the Board

The following disclosure appeared in the June 30, 2006 Annual Report of the Fund
and is the discussion referred to in "New BlackRock Sub-Advisory Agreement --
Matters Considered by the Board" below. The term "Investment Adviser" as used
herein refers to Merrill Lynch Investment Managers, L.P.

In connection with the Transaction between Merrill Lynch and BlackRock, the
Trust's Board of Trustees 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 Trust's shareholders, it will become effective upon
the expected closing of the Transaction, which is expected in the third quarter
of 2006.

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

To assist the 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 meeting. In addition, the independent trustees consulted with their counsel
and Trust counsel on numerous occasions, discussing, among other things, the
legal standards and certain other considerations relevant to the trustees'
deliberations.

At the Board meetings, 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 Trust. At these Board
meetings, representatives of Merrill Lynch and BlackRock made presentations to
and responded to questions from the Board. The trustees 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 of the
Board 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 the Board's review of the New Investment Advisory Agreement,
Merrill Lynch and/or BlackRock advised the trustees about a variety of matters.
The advice included the following, among other matters:

o     that there is not expected to be any diminution in the nature, quality and
      extent of services provided to the Trust and its shareholders by BlackRock
      Advisors, including compliance services;

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

o     that the 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;

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

o     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

o     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 Trust
      shareholders.

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


       BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006     21


Disclosure of Investment Advisory Agreement (continued)

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

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

o     the compliance policies and procedures of BlackRock Advisors;

o     the terms and conditions of the New Investment Advisory Agreement,
      including the fact that the schedule of the Trust's total advisory fees
      will not increase by virtue of the New Investment Advisory Agreement, but
      will remain the same;

o     that in November 2005, the Board had performed a full annual review of the
      investment advisory agreement currently in effect for the Trust (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 Trust; and that the advisory and/or
      management fees paid by the 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; and

o     that Merrill Lynch agreed to pay all expenses of the Trust in connection
      with the 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 the Trust would bear no
      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, the Board assessed the
nature, scope and quality of the services to be provided to 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, the 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 Trust; (b) Trust operating expenses paid to third parties; (c)
the resources devoted to and compliance reports relating to the Trust's
investment objective, policies and restrictions, and its compliance with its
Code of Ethics and BlackRock Advisors' compliance policies and procedures; and
(d) the nature, cost and character of non-investment management services to be
provided by BlackRock Advisors and its affiliates.

In the period prior to the Board meeting to consider renewal of the Current
Investment Advisory Agreement, the Board had requested and received materials
specifically relating to the Current Investment Advisory Agreement. These
materials included (a) information compiled by Lipper on the fees and expenses
and the investment performance of the Trust 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 Trust; and (d) information
provided by the Investment Adviser concerning services related to the valuation
and pricing of the Trust's portfolio holdings, allocation of 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 Trust.

In their deliberations, the trustees considered information received in
connection with their most recent continuation of the Current Investment
Advisory Agreement, in addition to information provided by BlackRock and
BlackRock Advisors in connection with their evaluation of the terms and
conditions of the 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. The trustees,
including a majority of the 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 Trust, and that
the New Invest-


22     BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006


ment Advisory Agreement should be approved and recommended to Trust
shareholders.

Nature, Quality and Extent of Services Provided -- The 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
Trust, as well as the nature, quality and extent of services expected to be
provided by BlackRock Advisors. The Board focused primarily on the Investment
Adviser's investment advisory services and the Trust's investment performance,
but also considered certain areas in which both the Investment Adviser and the
Trust receive services as part of the Merrill Lynch complex. The Board compared
the Trust's performance -- both including and excluding the effects of the
Trust'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
the Board reviews performance data at least quarterly, consistent with the
Investment Adviser's investment goals, the Board attaches more importance to
performance over relatively long periods of time.

In evaluating the nature, quality and extent of the services to be provided by
BlackRock Advisors under the New Investment Advisory Agreement, the trustees
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 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 Trust.

The trustees were given information with respect to the potential benefits to
the Trust and its 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.

The trustees were advised that, as a result of Merrill Lynch's equity interest
in BlackRock after the Transaction, the 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. The trustees were 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 Trust
under the New Investment Advisory Agreement were expected to be as good as or
better than that provided under the 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. The trustees
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, the trustees concluded that, overall, they were 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 Trust
under the New Investment Advisory Agreement.

Costs of Services Provided and Profitability -- It was noted that, in
conjunction with the recent review of the Current Investment Advisory Agreement,
the trustees had received, among other things, a report from Lipper comparing
the Trust'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. The Board reviewed the Trust's contractual management fee
rate and actual management fee rate as a percentage of total assets at common
asset evels -- the actual rate includes advisory fees and the effects of any fee
waivers -- compared to the other funds in its Lipper category. They also
compared the Trust's total expenses to those of other comparable funds. The
information showed that the Trust had fees and expenses within the range of fees
and expenses of comparable funds. The Board noted that if all assets are
irreversibly allocated to the Protection Component under the terms of the
Trust's Warranty Agreement, the management fee will be reduced. The Board
concluded that the 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, the trustees considered, among
other things, whether advisory fees or other expenses would change as a result
of the Transaction. Based on their review of the materials provided and the fact
that the New Investment Advisory Agreement is substantially similar to the
Current Investment


       BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006     23


Disclosure of Investment Advisory Agreement (concluded)

Advisory Agreement in all material respects, including the rate of compensation,
the trustees determined that the Transaction should not increase the total fees
payable, including any fee waivers and expense reimbursements, for advisory and
administrative services. The trustees noted that it was not possible to predict
with certainty New BlackRock's future profitability from its relationship with
the Trust.

The trustees discussed with BlackRock Advisors its general methodology to be
used in determining New BlackRock's profitability with respect to its
relationship with the Trust. The trustees noted that they expect 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 the Trust's fees
and/or fee breakpoints would be appropriate.

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

In reviewing the Transaction, the trustees 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, the trustees determined
that as a result of the Transaction, the Trust's total advisory fees would be no
higher than the fees under its Current Investment Advisory Agreement. The
trustees noted that in conjunction with their most recent deliberations
concerning the Current Investment Advisory Agreement, they had determined that
the total fees for advisory and administrative services for the 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, the
trustees had received, among other things, a report from Lipper comparing the
Trust'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.
The trustees concluded that, because the rates for advisory fees for the Trust
would be no higher than its current fee rates, the proposed management fee
structure, including any fee waivers, was reasonable and that no additional
changes were currently necessary.

Fall-Out Benefits -- In evaluating the fall-out benefits to be received by
BlackRock Advisors under the New Investment Advisory Agreement, the trustees
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 to obtain research services using
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 Trust following the
Transaction. The trustees noted that any benefits were difficult to quantify
with certainty at this time, and indicated that they would continue to evaluate
them going forward.

Investment Performance -- The trustees considered investment performance for the
Trust. The trustees compared the Trust's performance -- both including and
excluding the effects of the Trust'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. The comparative information received from Lipper showed
Trust performance at various levels within the range of performance of
comparable funds over different time periods. While the Board reviews
performance data at least quarterly, consistent with the Investment Adviser's
investment goals, the Board attaches more importance over relatively long
periods of time. The trustees believed the Trust's performance was satisfactory.
Also, the trustees took into account the investment performance of funds
currently advised by BlackRock Advisors. The 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. The 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 Trust.

Conclusion -- After the independent trustees of the Trust deliberated in
executive session, the 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


24     BLACKROCK BASIC VALUE PRINCIPAL PROTECTED FUND   DECEMBER 31, 2006


New Investment Advisory Agreement was in the best interests of the shareholders.
In approving the New Investment Advisory Agreement, the 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 the Board

At the telephonic and in-person meetings held during April and May 2006 at which
the Board of Trustees discussed and approved the New Investment Advisory
Agreement, the 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 the Board deems it necessary and
in the best interests of the Trust and its 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 the 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 the Trust's expenses as a result of
the Contingent Sub-Advisory Agreement.

In making its approval at the May in-person meeting, the Board considered the
Contingent Sub-Advisory Agreement in conjunction with the New Investment
Advisory Agreement and reviewed the same information and factors discussed
above. The 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, the
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 Trust's operations and administration and the BlackRock
Sub-Adviser would provide advisory services to the Trust under the Contingent
Sub-Advisory Agreement. The 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 Trust would not increase as a result of the
Contingent Sub-Advisory Agreement. Under all of the circumstances, the 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, the 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 Agreement -- Matters Considered by the Board

At an in-person meeting held on August 24-25, 2006, the Board of Trustees,
including the independent trustees, discussed and approved the sub-advisory
agreement with respect to the Fund between BlackRock Advisors, LLC (previously
organized as BlackRock Advisors, Inc.) ("BlackRock Advisors") and its affiliate,
BlackRock Investment Management, LLC (the "Sub-Adviser") (the "BlackRock
Sub-Advisory Agreement"). The BlackRock Sub-Advisory Agreement 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 BlackRock Sub-Advisory Agreement, the Sub-Adviser receives a
monthly fee from BlackRock Advisors at an annual rate equal to 74% of the
advisory fee received by BlackRock Advisors from the Fund. BlackRock Advisors
pays the Sub-Adviser out of its own resources, and there is no increase in Fund
expenses as a result of the BlackRock Sub-Advisory Agreement.

In approving the BlackRock Sub-Advisory Agreement at the August in-person
meeting, the Board reviewed its considerations in connection with its approval
of the New Investment Advisory Agreement in May 2006. The Board 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
Agreement, the Board noted the fact that both BlackRock Advisors and the
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 for oversight of
the Fund's operations and administration. Under the BlackRock Sub-Advisory
Agreement, the Sub-Adviser provides advisory services to the Fund and is
responsible for the day-to-day management of the Fund's portfolio. The Board
also took into account the fact that there is no increase in total advisory fees
paid by the Fund as a result of the BlackRock Sub-Advisory Agreement. Based on
its considerations, the Board concluded that it was a reasonable allocation of
fees for the Sub-Adviser to receive a fee at an annual rate equal to 74% of the
advisory fee paid by the Fund to BlackRock Advisors.

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