The Benefits and Risks of Leveraging

The Funds utilize leverage through the issuance of Preferred Stock. The concept
of leveraging is based on the premise that the cost of assets to be obtained
from leverage will be based on short-term interest or dividend rates on the
Preferred Stock, which normally will be lower than the income earned by each
Fund on its longer-term portfolio investments. To the extent that the total
assets of each Fund (including the assets obtained from leverage) are invested
in higher-yielding portfolio investments, each Fund's Common Stock shareholders
will be the beneficiaries of the incremental yield.

Leverage creates risks for holders of Common Stock including the likelihood of
greater net asset value and market price volatility. In addition, there is the
risk that fluctuations in the dividend rates on any Preferred Stock may reduce
the Common Stock's yield and negatively impact its net asset value and market
price. If the income derived from securities purchased with assets received from
leverage exceeds the cost of leverage, each Fund's net income will be greater
than if leverage had not been used. Conversely, if the income from the
securities purchased is not sufficient to cover the cost of leverage, each
Fund's net income will be less than if leverage had not been used, and therefore
the amount available for distribution to Common Stock shareholders will be
reduced.

A Letter From the President

Dear Shareholder

As the financial markets continued to muddle their way through 2005, the Federal
Reserve Board (the Fed) advanced its monetary tightening campaign full steam
ahead. The 12th consecutive interest rate hike since June 2004 came on November
1, bringing the target federal funds rate to 4%. The central bank is clearly
more focused on inflationary figures than on economic growth, which has shown
some signs of moderating. Despite rising short-term interest rates and
record-high energy prices, the major market indexes managed to post positive
results for the current reporting period:

The headlines in recent months focused on Hurricanes Katrina and Rita and, more
recently, the nomination of Ben Bernanke to succeed Alan Greenspan as Chairman
of the Fed. While the hurricanes prompted a spike in energy prices and
short-term disruptions to production and spending, the longer-term economic
impact is likely to be tempered. In fact, the fiscal stimulus associated with
reconstruction efforts in the Gulf Coast region could add to gross domestic
product growth in 2006. Notably, the uncontroversial nomination of Dr. Bernanke
was well received by the markets.

The U.S. equity markets remained largely range bound in 2005. Up to this point,
strong corporate earnings reports and relatively low long-term bond yields have
worked in favor of equities. Looking ahead, high energy prices, continued
interest rate hikes, a potential consumer slowdown and/or disappointing earnings
pose the greatest risks to U.S. stocks. Internationally, many markets have
benefited from strong economic statistics, trade surpluses and solid finances.

The bond market continued to be characterized by a flattening yield curve,
although long-term yields finally began to inch higher toward period end. The
10-year Treasury yield hit 4.57% on October 31, 2005, its highest level in more
than six months. Still, the difference between the two-year and 10-year Treasury
yield was just 17 basis points (.17%) at period end, compared to 149 basis
points a year earlier.

Financial markets are likely to face continued crosscurrents in the months
ahead. Nevertheless, opportunities do exist and we encourage you to work with
your financial advisor to diversify your portfolio among a variety of asset
types. This can help to diffuse risk while also tapping into the potential
benefits of a broader range of investment alternatives. As always, we thank you
for trusting Merrill Lynch Investment Managers with your investment assets.

                                           Sincerely,


                                           /s/ Robert C. Doll, Jr.

                                           Robert C. Doll, Jr.

A Discussion With Your Funds' Portfolio Managers

      The Funds outperformed their benchmark for the fiscal year, benefiting
from considerably underweight positions in U.S. agency securities and a
substantial weighting in $25 par retail preferred issues.

Describe the market and economic environment during the period.

The yield curve flattened considerably as the rise in short-term interest rates
outpaced that of long-term interest rates during the past 12 months. The yield
difference between two-year and 10-year U.S. Treasury issues was just 17 basis
points (.17%) at period-end, compared to 149 basis points 12 months earlier.
Record-high oil prices and strong gross domestic product (GDP) growth led to
increased fears of inflation. GDP grew at an estimated annualized rate of 3.8%
in the third quarter of 2005, compared to 3.8% and 3.3% for the first and second
quarters, respectively. The yield on the 10-year Treasury note rose from 4.05%
on October 31, 2004, to 4.57% at period-end. The Federal Reserve Board (the Fed)
raised short-term interest rates in eight increments of .25% during the period.
The target federal funds rate stood at 3.75% at October 31, 2005, and was raised
to 4% one day after period-end on November 1.

Led by a 42.5% increase in energy costs, the Consumer Price Index (CPI) climbed
at a non-seasonally adjusted annualized rate of 5.1% for the first three
quarters of 2005, up significantly from the 3.3% increase for all of 2004.
However, the annualized rise in food prices was just 1.9% during the most recent
calendar quarter. Therefore, excluding food and energy costs, the CPI advanced
at a non-seasonally adjusted annualized rate of 1.4% for the third quarter of
2005.

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

For the 12-month period ended October 31, 2005, the Common Stock of Preferred
Income Strategies Fund, Inc. had net annualized yields of 8.98% and 9.43%, based
on a year-end per share net asset value of $22.26 and a per share market price
of $21.20, respectively, and $2.000 per share income dividends. For the same
period, the total investment return on the Fund's Common Stock was +3.73%, based
on a change in per share net asset value from $23.48 to $22.26, and assuming
reinvestment of all distributions.

The Common Stock of Preferred and Corporate Income Strategies Fund, Inc. had net
annualized yields of 8.94% and 9.51% for the year ended October 31, 2005, based
on a year-end per share net asset value of $22.36 and a per share market price
of $21.03, respectively, and $2.000 per share income dividends. The total
investment return on the Fund's Common Stock was +3.25% for the year, based on a
change in per share net asset value from $23.69 to $22.36, and assuming
reinvestment of all distributions.

For the same 12-month period, the Funds' benchmark, the Merrill Lynch Preferred
Stock Fixed Rate Index, returned +1.07%, while the broader-market Merrill Lynch
U.S. Corporate Master Index and the Merrill Lynch U.S. Treasury/Agency Master
Index returned +.80% and +.98%, respectively.

The Funds' relative performance during the fiscal year benefited from their
significant underweight positions in U.S. agency securities (Federal National
Mortgage Association, or "Fannie Mae," and Federal Home Loan Mortgage
Corporation, or "Freddie Mac"). The prices of these issues declined amid
investor concerns about accounting irregularities and uncertainty regarding the
possibility of increased oversight of the agencies by the federal government. A
substantial weighting in $25 par retail preferred issues and an overweight
position in floating rate preferred securities also enhanced performance.
Conversely, our overweight positions in foreign bank tier 1 (large
capitalization European banks) securities detracted from relative returns, as
these issues generally underperformed during the year.

For the six-month period ended October 31, 2005, the total investment return on
Preferred Income Strategies Fund's Common Stock was +.07%, based on a change in
per share net asset value from $23.27 to $22.26, and assuming reinvestment of
all distributions. The total investment return on Preferred and Corporate Income
Strategies Fund's Common Stock was +.04%, based on a change in per share net
asset value from $23.38 to $22.36, and assuming reinvestment of all
distributions. For the same period, the benchmark Merrill Lynch Preferred Stock
Fixed Rate Index returned +1.58%, while the Merrill Lynch U.S. Corporate Master
Index and the Merrill Lynch U.S. Treasury/Agency Master Index returned -.03% and
+.08%, respectively.

For a description of the Funds' total investment returns based on a change in
the per share market value of the Funds' Common Stock (as measured by the
trading price of the Funds' shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial


4                   ANNUAL REPORTS        OCTOBER 31, 2005


Highlights section of this report. As closed-end funds, the Funds' shares may
trade in the secondary market at a premium or discount to their net asset
values. As a result, total investment returns based on changes in the market
value of the Funds' Common Stock can vary significantly from total investment
returns based on changes in the Funds' net asset values.

What changes were made to the portfolios during the period?

Early in the fiscal year, we reduced the portfolios' durations -- which already
were shorter than that of their benchmark -- by approximately six months. This
was in keeping with our view that the Fed would continue to raise short-term
interest rates gradually, forcing long-term rates higher. We then increased each
Fund's duration by 2.5 years in mid April as the economy displayed signs of
slowing, which we believed would lead to a rally in U.S. Treasury securities.
This positioning benefited performance until July, when we reduced each
portfolio's duration by 1.5 years as it again appeared that the Fed would
continue to raise short-term rates. Consequently, the net change in each Fund's
duration during the fiscal year was an increase of nine months.

In addition, we reduced the portfolios' holdings in real estate investment
trusts based on our concerns about the increasingly speculative U.S. housing
market. We also trimmed our positions in the banking sector given our belief
that these securities are overvalued. We reinvested the proceeds from our sales
in securities of property and casualty and life insurance companies, as we
believe these issues had attractive valuations following their price declines in
the wake of projected losses resulting from the damage to the Gulf Coast caused
by Hurricanes Katrina and Rita.

We used net asset value hedges earlier in the fiscal year to shorten the
portfolios' duration in an effort to reduce the risk of loss in value associated
with rising interest rates. Among the hedges we implemented were pay-fixed
interest rate swaps, in which we entered into agreements to pay a fixed rate of
interest and receive variable interest payments in return.

How would you characterize the Funds' positioning at the close of the period?

We have positioned the Funds in an effort to protect their net asset values from
the downside risks associated with rising interest rates. We maintain our focus
on the financial sector, as our largest absolute weightings at the end of the
period were in banking and insurance issues, which comprised approximately 38%
and 45% of the net assets of Preferred Income Strategies Fund and Preferred and
Corporate Income Strategies Fund, respectively. The portfolios are well
diversified among issuers, and we intend to maintain this diversification.

At October 31, 2005, Preferred Income Strategies Fund and Preferred and
Corporate Income Strategies Fund had leveraged positions of approximately 36%
and 37%, respectively, of their total net assets. (For a more complete
explanation of the benefits and risks of leveraging, see page 2 of this report
to shareholders.) Also at period-end, each portfolio carried an average credit
rating of Baa1 from Moody's Investors Service. The average ratings for the Funds
remained unchanged for the fiscal year.

Notes to Financial Statements

1. Significant Accounting Policies:

Preferred and Corporate Income Strategies Fund, Inc. and Preferred Income
Strategies Fund, Inc. (the "Funds" or individually as the "Fund") are registered
under the Investment Company Act of 1940, as amended, as diversified, closed-end
management investment companies. The Funds' financial statements are prepared in
conformity with U.S. generally accepted accounting principles, which may require
the use of management accruals and estimates. Actual results may differ from
these estimates. The Funds' Common Stock shares are listed on the New York Stock
Exchange ("NYSE") under the symbol PSW for Preferred and Corporate Income
Strategies Fund, Inc. and PSY for Preferred Income Strategies Fund, Inc. The
following is a summary of significant accounting policies followed by the Funds.

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

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

Generally, trading in foreign securities is substantially completed each day at
various times prior to the close of business on the 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 also are generally
determined prior to 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 in each 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 may be valued at their
fair value as determined in good faith by the Fund's Board of Directors or by
the Investment Adviser using a pricing service and/or procedures approved by the
Fund's Board of Directors.

(b) Derivative financial instruments -- Each Fund may engage in various
portfolio investment strategies both to increase the return of each 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     Options -- Each 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


20                  ANNUAL REPORTS        OCTOBER 31, 2005


Notes to Financial Statements (continued)

current market value of the option written. When a security is purchased or sold
through an exercise of an option, the related premium paid (or received) is
added to (or deducted from) the basis of the security acquired or deducted from
(or added to) the proceeds of the security sold. When an option expires (or the
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.

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

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

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

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

(f) Securities lending -- Each 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.

(g) Reclassifications -- Preferred and Corporate Income Strategies Fund, Inc.
U.S. generally accepted accounting principles require that certain components of
net assets be adjusted to reflect


                    ANNUAL REPORTS        OCTOBER 31, 2005                    21


Notes to Financial Statements (continued)

permanent differences between financial and tax reporting. Accordingly, during
the current year, $3,376,722 has been reclassified between accumulated realized
capital losses and undistributed net investment income as a result of permanent
differences attributable to the classification of investments, gains from the
sale of stock of passive foreign investment companies, and swap agreements. This
reclassification has no effect on net assets or net asset values per share.

Preferred Income Strategies Fund, Inc.

U.S. generally accepted accounting principles require that certain components of
net assets be adjusted to reflect permanent differences between financial and
tax reporting. Accordingly, during the current year, $14,645,385 has been
reclassified between accumulated net realized capital losses and undistributed
net investment income and $3,374 has been reclassified between paid-in capital
in excess of par and undistributed net investment income as a result of
permanent differences attributable to swap transactions, the classification of
investments, passive foreign investment companies and non-deductible expenses.
These reclassifications have no effect on net assets or net asset values per
share.

2. Investment Advisory Agreement and Transactions with Affiliates:

Each Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of each Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, each Fund pays a monthly fee
at an annual rate of .60% of the Fund's average daily (for Preferred and
Corporate Income Strategies Fund, Inc.) and weekly (for Preferred Income
Strategies Fund, Inc.) net assets (including proceeds from the issuance of
Preferred Stock) plus the proceeds of any outstanding borrowings used for
leverage.

Each Fund has received an exemptive order from the Securities and Exchange
Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce,
Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, or its affiliates.
Pursuant to that order, the Fund also has retained Merrill Lynch Investment
Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending
agent for a fee based on a share of the returns on investment of cash
collateral. MLIM, LLC may, on behalf of the Fund, invest cash collateral
received by the Fund for such loans, among other things, in a private investment
company managed by MLIM, LLC or in registered money market funds advised by FAM
or its affiliates. For the year ended October 31, 2005, MLIM, LLC received
$1,218 in securities lending agent fees for the Preferred Income Strategies
Fund, Inc.

For the year ended October 31, 2005, each Fund reimbursed FAM for certain
accounting services. The reimbursements were as follows:

--------------------------------------------------------------------------------

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of
Preferred and Corporate Income Strategies
Fund, Inc. and Preferred Income Strategies
Fund, Inc.:

We have audited the accompanying statements of net assets of Preferred and
Corporate Income Strategies Fund, Inc. and Preferred Income Strategies Fund,
Inc. (the "Funds"), including the schedule of investments, as of October 31,
2005, the related statements of operations for the year then ended, the
statements of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the periods indicated therein.
These financial statements and financial highlights are the responsibility of
the Funds' management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Funds' internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of October 31, 2005, by correspondence with the custodian
and brokers. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, such financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
Preferred and Corporate Income Strategies Fund, Inc. and Preferred Income
Strategies Fund, Inc. at October 31, 2005, the results of their operations for
the year then ended, the changes in their net assets for each of the two years
in the period then ended, and their financial highlights for each of the periods
indicated therein, in conformity with U.S. generally accepted accounting
principles.

Automatic Dividend Reinvestment Plan

How the Plan Works -- The Funds offer a Dividend Reinvestment Plan (the "Plan")
under which income and capital gains dividends paid by each Fund are
automatically reinvested in additional shares of Common Stock of each Fund. The
Plan is administered on behalf of the shareholders by Equiserve Trust Company
N.A. (the "Plan Agent"). Under the Plan, whenever the Funds declare a dividend,
participants in the Plan will receive the equivalent in shares of Common Stock
of each Fund. The Plan Agent will acquire the shares for the participant's
account either (i) through receipt of additional unissued but authorized shares
of each Fund ("newly issued shares") or (ii) by purchase of outstanding shares
of Common Stock on the open market on the New York Stock Exchange or elsewhere.
If, on the dividend payment date, each Fund's net asset value per share is equal
to or less than the market price per share plus estimated brokerage commissions
(a condition often referred to as a "market premium"), the Plan Agent will
invest the dividend amount in newly issued shares. If the Funds' net asset value
per share is greater than the market price per share (a condition often referred
to as a "market discount"), the Plan Agent will invest the dividend amount by
purchasing on the open market additional shares. If the Plan Agent is unable to
invest the full dividend amount in open market purchases, or if the market
discount shifts to a market premium during the purchase period, the Plan Agent
will invest any uninvested portion in newly issued shares. The shares acquired
are credited to each shareholder's account. The amount credited is determined by
dividing the dollar amount of the dividend by either (i) when the shares are
newly issued, the net asset value per share on the date the shares are issued or
(ii) when shares are purchased in the open market, the average purchase price
per share.

Participation in the Plan -- Participation in the Plan is automatic, that is, a
shareholder is automatically enrolled in the Plan when he or she purchases
shares of Common Stock of the Funds unless the shareholder specifically elects
not to participate in the Plan. Shareholders who elect not to participate will
receive all dividend distributions in cash. Shareholders who do not wish to
participate in the Plan, must advise the Plan Agent in writing (at the address
set forth below) that they elect not to participate in the Plan. Participation
in the Plan is completely voluntary and may be terminated or resumed at any time
without penalty by writing to the Plan Agent.

Benefits of the Plan -- The Plan provides an easy, convenient way for
shareholders to make additional, regular investments in the Funds. The Plan
promotes a long-term strategy of investing at a lower cost. All shares acquired
pursuant to the Plan receive voting rights. In addition, if the market price
plus commissions of each Fund's shares is above the net asset value,
participants in the Plan will receive shares of the Funds for less than they
could otherwise purchase them and with a cash value greater than the value of
any cash distribution they would have received. However, there may not be enough
shares available in the market to make distributions in shares at prices below
the net asset value. Also, since each Fund does not redeem shares, the price on
resale may be more or less than the net asset value.

Plan Fees -- There are no enrollment fees or brokerage fees for participating in
the Plan. The Plan Agent's service fees for handling the reinvestment of
distributions are paid for by the Funds. However, brokerage commissions may be
incurred when the Funds purchase shares on the open market and shareholders will
pay a pro rata share of any such commissions.

Tax Implications -- The automatic reinvestment of dividends and distributions
will not relieve participants of any federal, state or local income tax that may
be payable (or required to be withheld) on such dividends. Therefore, income and
capital gains may still be realized even though shareholders do not receive
cash.

Contact Information -- All correspondence concerning the Plan, including any
questions about the Plan, should be directed to the Plan Agent at Equiserve
Trust Company N.A. (c/o Computershare Investor Services), P.O. Box 43010,
Providence, RI 02940-3010, Telephone: 800-426-5523.

Disclosure of Investment Advisory Agreement

Activities of and Composition of the Board of Directors

All but one member of each Fund's Board of Directors is an independent director
whose only affiliation with Fund Asset Management, L.P. (the "Investment
Adviser") or other Merrill Lynch affiliates is as a director of each Fund and
certain other funds advised by the Investment Adviser or its affiliates. The
Chair of each Board is also an independent director. New director nominees are
chosen as nominees by a Nominating Committee comprised of independent directors.
All independent directors also are members of each Board's Audit Committee and
the independent directors meet in executive session at each in-person Board
meeting. The Board and the Audit Committee meet in person for at least two days
each quarter and conduct other in-person and telephone meetings throughout the
year, some of which are formal board meetings, and some of which are
informational meetings. The independent counsel to the independent directors
attends all in-person Board and Audit Committee meetings and other meetings at
the independent directors' request.

Investment Advisory Agreements -- Matters Considered by the Board

Every year, each Board considers approval of each Fund's investment advisory
agreement (the "Investment Advisory Agreement"). Each Board assesses the nature,
scope and quality of the services provided to each Fund by the personnel of the
Investment Adviser and its affiliates, including administrative services,
shareholder services, oversight of fund accounting, marketing services and
assistance in meeting legal and regulatory requirements. Each Board also
receives and assesses information regarding the services provided to the Fund by
certain unaffiliated service providers.

At various times throughout the year, each Board also considers a range of
information in connection with its oversight of the services provided by the
Investment Adviser and its affiliates. Among the matters considered are: (a)
fees (in addition to management fees) paid to the Investment Adviser and its
affiliates by each Fund; (b) Fund operating expenses paid to third parties; (c)
the resources devoted to and compliance reports relating to each Fund's
investment objective, policies and restrictions, and its compliance with its
Code of Ethics and the Investment Adviser's compliance policies and procedures;
and (d) the nature, cost and character of non-investment management services
provided by the Investment Adviser and its affiliates.

Each Board believes that the Investment Adviser is one of the most experienced
global asset management firms and considers the overall services provided by the
Investment Adviser to be generally of high quality. Each Board also believes
that the Investment Adviser is financially sound and well managed and notes that
the Investment Adviser is affiliated with one of America's largest financial
firms. Each Board works closely with the Investment Adviser in overseeing the
Investment Adviser's efforts to achieve good performance. As part of this
effort, each Board discusses portfolio manager effectiveness and, when
performance is not satisfactory, discusses with the Investment Adviser taking
steps such as changing investment personnel.

Annual Consideration of Approvals by the Board of Directors

In the period prior to the Board meeting to consider renewal of the Investment
Advisory Agreement, each Board requests and receives materials specifically
relating to the Fund's Investment Advisory Agreement. These materials are
prepared separately for each Fund, and include (a) information compiled by
Lipper Inc. ("Lipper") on the fees and expenses and the investment performance
of the Fund as compared to a comparable group of funds as classified by Lipper;
(b) information comparing the Fund's market price with its net asset value per
share; (c) a discussion by the Fund's portfolio management team of investment
strategies used by the Fund during its most recent fiscal year; (d) information
on the profitability to the Investment Adviser and its affiliates of the
Investment Advisory Agreement and other relationships with the Fund; and (e)
information provided by the Investment Adviser concerning investment advisory
fees charged to other clients, such as offshore funds under similar investment
mandates and generally to institutional clients. Each Board also considers other
matters it deems important to the approval process such as services related to
the valuation and pricing of Fund portfolio holdings, allocation of Fund
brokerage fees, the Fund's portfolio turnover statistics, and direct and
indirect benefits to the Investment Adviser and its affiliates from their
relationship with the Fund.

Certain Specific Renewal Data

In connection with the most recent renewal of each Fund's Investment Advisory
Agreement in May 2005, the independent directors' and Board's review included
the following:

Services Provided by the Investment Adviser -- Each Board reviewed the nature,
extent and quality of services provided by the Investment Adviser, including the
investment advisory services and the resulting performance of the Fund. Each
Board focused primarily on the Investment Adviser's investment advisory services
and the Fund's investment performance, having concluded that the other services
provided to


28                  ANNUAL REPORTS        OCTOBER 31, 2005


the Fund by the Investment Adviser were satisfactory. Each Board
compared Fund performance -- both including and excluding the effects of the
Fund's fees and expenses -- to the performance of a comparable group of funds,
and the performance of a relevant index or combination of indexes. While each
Board reviews performance data at least quarterly, consistent with the
Investment Adviser's investment goals, each Board attaches more importance to
performance over relatively long periods of time, typically three to five years
or, in the case of a fund that, like the Funds, has been in operations for less
than three years, performance since inception. Each Fund ranked in the fifth
quintile for the one-year and since inception periods ended March 31, 2005. The
Directors also requested and considered additional information from the
Investment Adviser analyzing the Funds' performance compared to investors'
expectations and in light of the interest rate environment since inception.
Considering all of these factors, each Board concluded that the Fund's
performance supported the continuation of the Investment Advisory Agreement.

The Investment Adviser's Personnel and Investment Process -- Each Board reviews
at least annually the Fund's investment objectives and strategies. Each Board
discusses with senior management of the Investment Adviser responsible for
investment operations and the senior management of the Investment Adviser's
taxable fixed-income investing group the strategies being used to achieve the
stated objectives. Among other things, the Board considers the size, education
and experience of the Investment Adviser's investment staff, its use of
technology, and the Investment Adviser's approach to training and retaining
portfolio managers and other research, advisory and management personnel. Each
Board also reviews the Investment Adviser's compensation policies and practices
with respect to the Fund's portfolio managers. Each Board also considered the
experience of the Fund's portfolio managers. Each Board noted that Messrs.
Burger and Musmanno have more than twelve and eight years of investment
experience, respectively. The Investment Adviser and its investment staff have
extensive experience in analyzing and managing the types of investments used by
the Funds. Each Board concluded that the Fund benefits from that expertise.

Management Fees and Other Expenses -- Each Board reviews the Fund's contractual
management fee rate and actual management fee rate as a percentage of total
assets at common asset levels -- the actual rate includes advisory and
administrative service fees and the effects of any fee waivers -- compared to
the other funds in its Lipper category. It also compares the Fund's total
expenses to those of other comparable funds. Each Board considered the services
provided to and the fees charged by the Investment Adviser to other types of
clients such as offshore funds, with similar investment mandates and noted that
the fees charged by the Investment Adviser in those cases typically exceeded
those being charged to the Fund. Each Board also noted that, as a general
matter, fees charged to institutional clients were lower than the fees charged
to the Fund, but believed that less extensive services were being provided to
such clients. Preferred and Corporate Income Strategies Fund, Inc.'s contractual
management fee rate, actual management fee rate, and total expenses are lower
than the median fees and expenses charged by comparable funds as determined by
Lipper. Preferred Income Strategies Fund, Inc.'s contractual management fee rate
is below, actual management fee rate is equal to, and total expenses are
slightly higher than, the fees and expenses charged by such comparable funds.
Each Board has concluded that the Fund's management fee and fee rate and overall
expense ratio are reasonable compared to those of other comparable funds.

Profitability -- Each Board considers the cost of the services provided to the
Fund by the Investment Adviser, and the Investment Adviser's and its affiliates'
profits relating to the management and distribution of the Fund and the
MLIM/FAM-advised funds. As part of its analysis, each Board reviewed the
Investment Adviser's methodology in allocating its costs to the management of
the Fund and concluded that there was a reasonable basis for the allocation.
Each Board believes the Investment Adviser's profits are reasonable in relation
to the nature and quality of services provided. The Boards also considered the
federal court decisions discussing an investment adviser's profitability and
profitability levels considered to be reasonable in those decisions.

Economies of Scale -- Each Board considered the extent to which economies of
scale might be realized as the assets of the Fund increase and whether there
should be changes in the management fee rate or structure in order to enable the
Fund to participate in these economies of scale. Each Board considered economies
of scale to the extent applicable to each Fund's closed-end structure and
determined that each Fund's management fee currently appropriately reflects
economies of scale.

Conclusion

After the independent directors deliberated in executive session, each entire
Board, including all of the independent directors, approved the renewal of the
existing Investment Advisory Agreement, concluding that the advisory fee was
reasonable in relation to the services provided and that a contract renewal was
in the best interests of the shareholders.

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

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

         The registrant's board of directors has determined that David O. Beim,

         reporting as well as audit committee functions. For 25 years, Mr. Beim
         was an investment banker actively engaged in financial analysis for
         securities transactions and mergers. These transactions presented a
         breadth and level of complexity of accounting issues that are generally
         comparable to the breadth and complexity of issues that can reasonably
         be expected to be raised by the Registrant's financial statements. Mr.

         University Graduate School of Business for the past 12 years.

         Prof. Kester has a thorough understanding of generally accepted

         has been involved in providing valuation and other financial consulting
         services to corporate clients since 1978. Prof. Kester's financial
         consulting services present a breadth and level of complexity of
         accounting issues that are generally comparable to the breadth and
         complexity of issues that can reasonably be expected to be raised by
         the Registrant's financial statements.

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

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

         the provision of non-audit services that were rendered to the
         registrant's investment adviser and any entity controlling, controlled
         by, or under common control with the investment adviser that provides
         ongoing services to the registrant that were not pre-approved pursuant
         to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible

Item 7 - Disclosure of Proxy Voting Policies and Procedures for Closed-End
         Management Investment Companies -
         Proxy Voting Policies and Procedures

         Each Fund's Board of Directors/Trustees has delegated to Merrill Lynch
         Investment Managers, L.P. and/or Fund Asset Management, L.P. (the
         "Investment Adviser") authority to vote all proxies relating to the
         Fund's portfolio securities. The Investment Adviser has adopted
         policies and procedures ("Proxy Voting Procedures") with respect to the
         voting of proxies related to the portfolio securities held in the
         account of one or more of its clients, including a Fund. Pursuant to
         these Proxy Voting Procedures, the Investment Adviser's primary
         objective when voting proxies is to make proxy voting decisions solely
         in the best interests of each Fund and its shareholders, and to act in
         a manner that the Investment Adviser believes is most likely to enhance
         the economic value of the securities held by the Fund. The Proxy Voting
         Procedures are designed to ensure that the Investment Adviser considers
         the interests of its clients, including the Funds, and not the
         interests of the Investment Adviser, when voting proxies and that real
         (or perceived) material conflicts that may arise between the Investment
         Adviser's interest and those of the Investment Adviser's clients are
         properly addressed and resolved.

         In order to implement the Proxy Voting Procedures, the Investment
         Adviser has formed a Proxy Voting Committee (the "Committee"). The
         Committee is comprised of the Investment Adviser's Chief Investment
         Officer (the "CIO"), one or more other senior investment professionals
         appointed by the CIO, portfolio managers and investment analysts
         appointed by the CIO and any other personnel the CIO deems appropriate.
         The Committee will also include two non-voting representatives from the
         Investment Adviser's Legal department appointed by the Investment
         Adviser's General Counsel. The Committee's membership shall be limited
         to full-time employees of the Investment Adviser. No person with any
         investment banking, trading, retail brokerage or research
         responsibilities for the Investment Adviser's affiliates may serve as a
         member of the Committee or participate in its decision making (except
         to the extent such person is asked by the Committee to present
         information to the Committee, on the same basis as other interested
         knowledgeable parties not affiliated with the Investment Adviser might
         be asked to do so). The Committee determines how to vote the proxies of
         all clients, including a Fund, that have delegated proxy voting
         authority to the Investment Adviser and seeks to ensure that all votes
         are consistent with the best interests of those clients and are free
         from unwarranted and inappropriate influences. The Committee
         establishes general proxy voting policies for the Investment Adviser
         and is responsible for determining how those policies are applied to
         specific proxy votes, in light of each issuer's unique structure,
         management, strategic options and, in certain circumstances, probable
         economic and other anticipated consequences of alternate actions. In so
         doing, the Committee may determine to vote a particular proxy in a
         manner contrary to its generally stated policies. In addition, the
         Committee will be responsible for ensuring that all reporting and
         recordkeeping requirements related to proxy voting are fulfilled.

         The Committee may determine that the subject matter of a recurring
         proxy issue is not suitable for general voting policies and requires a
         case-by-case determination. In such cases, the Committee may elect not
         to adopt a specific voting policy applicable to that issue. The
         Investment Adviser believes that certain proxy voting issues require
         investment analysis - such as approval of mergers and other significant
         corporate transactions - akin to investment decisions, and are,
         therefore, not suitable for general guidelines. The Committee may elect
         to adopt a common position for the Investment Adviser on certain proxy
         votes that are akin to investment decisions, or determine to permit the
         portfolio manager to make individual decisions on how best to maximize
         economic value for a Fund (similar to normal buy/sell investment
         decisions made by such portfolio managers). While it is expected that
         the Investment Adviser will generally seek to vote proxies over which
         the Investment Adviser exercises voting authority in a uniform manner
         for all the Investment Adviser's clients, the Committee, in conjunction
         with a Fund's portfolio manager, may determine that the Fund's specific
         circumstances require that its proxies be voted differently.



         To assist the Investment Adviser in voting proxies, the Committee has
         retained Institutional Shareholder Services ("ISS"). ISS is an
         independent adviser that specializes in providing a variety of
         fiduciary-level proxy-related services to institutional investment
         managers, plan sponsors, custodians, consultants, and other
         institutional investors. The services provided to the Investment
         Adviser by ISS include in-depth research, voting recommendations
         (although the Investment Adviser is not obligated to follow such
         recommendations), vote execution, and recordkeeping. ISS will also
         assist the Fund in fulfilling its reporting and recordkeeping
         obligations under the Investment Company Act.

         The Investment Adviser's Proxy Voting Procedures also address special
         circumstances that can arise in connection with proxy voting. For
         instance, under the Proxy Voting Procedures, the Investment Adviser
         generally will not seek to vote proxies related to portfolio securities
         that are on loan, although it may do so under certain circumstances. In
         addition, the Investment Adviser will vote proxies related to
         securities of foreign issuers only on a best efforts basis and may
         elect not to vote at all in certain countries where the Committee
         determines that the costs associated with voting generally outweigh the
         benefits. The Committee may at any time override these general policies
         if it determines that such action is in the best interests of a Fund.

From time to time, the Investment Adviser may be required to vote proxies in
respect of an issuer where an affiliate of the Investment Adviser (each, an
"Affiliate"), or a money management or other client of the Investment Adviser
(each, a "Client") is involved. The Proxy Voting Procedures and the Investment
Adviser's adherence to those procedures are designed to address such conflicts
of interest. The Committee intends to strictly adhere to the Proxy Voting
Procedures in all proxy matters, including matters involving Affiliates and
Clients. If, however, an issue representing a non-routine matter that is
material to an Affiliate or a widely known Client is involved such that the
Committee does not reasonably believe it is able to follow its guidelines (or if
the particular proxy matter is not addressed by the guidelines) and vote
impartially, the Committee may, in its discretion for the purposes of ensuring
that an independent determination is reached, retain an independent fiduciary to
advise the Committee on how to vote or to cast votes on behalf of the Investment
Adviser's clients.

         In the event that the Committee determines not to retain an independent
         fiduciary, or it does not follow the advice of such an independent
         fiduciary, the powers of the Committee shall pass to a subcommittee,
         appointed by the CIO (with advice from the Secretary of the Committee),
         consisting solely of Committee members selected by the CIO. The CIO
         shall appoint to the subcommittee, where appropriate, only persons
         whose job responsibilities do not include contact with the Client and
         whose job evaluations would not be affected by the Investment Adviser's
         relationship with the Client (or failure to retain such relationship).
         The subcommittee shall determine whether and how to vote all proxies on
         behalf of the Investment Adviser's clients or, if the proxy matter is,
         in their judgment, akin to an investment decision, to defer to the
         applicable portfolio managers, provided that, if the subcommittee
         determines to alter the Investment Adviser's normal voting guidelines
         or, on matters where the Investment Adviser's policy is case-by-case,
         does not follow the voting recommendation of any proxy voting service
         or other independent fiduciary that may be retained to provide research
         or advice to the Investment Adviser on that matter, no proxies relating
         to the Client may be voted unless the Secretary, or in the Secretary's
         absence, the Assistant Secretary of the Committee concurs that the
         subcommittee's determination is consistent with the Investment
         Adviser's fiduciary duties

         In addition to the general principles outlined above, the Investment
         Adviser has adopted voting guidelines with respect to certain recurring
         proxy issues that are not expected to involve unusual circumstances.
         These policies are guidelines only, and the Investment Adviser may
         elect to vote differently from the recommendation set forth in a voting
         guideline if the Committee determines that it is in a Fund's best
         interest to do so. In addition, the guidelines may be reviewed at any
         time upon the request of a Committee member and may be amended or
         deleted upon the vote of a majority of Committee members present at a
         Committee meeting at which there is a quorum.



         The Investment Adviser has adopted specific voting guidelines with
         respect to the following proxy issues:

o     Proposals related to the composition of the Board of Directors of issuers
      other than investment companies. As a general matter, the Committee
      believes that a company's Board of Directors (rather than shareholders) is
      most likely to have access to important, nonpublic information regarding a
      company's business and prospects, and is therefore best-positioned to set
      corporate policy and oversee management. The Committee, therefore,
      believes that the foundation of good corporate governance is the election
      of qualified, independent corporate directors who are likely to diligently
      represent the interests of shareholders and oversee management of the
      corporation in a manner that will seek to maximize shareholder value over
      time. In individual cases, the Committee may look at a nominee's history
      of representing shareholder interests as a director of other companies or
      other factors, to the extent the Committee deems relevant.

o     Proposals related to the selection of an issuer's independent auditors. As
      a general matter, the Committee believes that corporate auditors have a
      responsibility to represent the interests of shareholders and provide an
      independent view on the propriety of financial reporting decisions of
      corporate management. While the Committee will generally defer to a
      corporation's choice of auditor, in individual cases, the Committee may
      look at an auditors' history of representing shareholder interests as
      auditor of other companies, to the extent the Committee deems relevant.

o     Proposals related to management compensation and employee benefits. As a
      general matter, the Committee favors disclosure of an issuer's
      compensation and benefit policies and opposes excessive compensation, but
      believes that compensation matters are normally best determined by an
      issuer's board of directors, rather than shareholders. Proposals to
      "micro-manage" an issuer's compensation practices or to set arbitrary
      restrictions on compensation or benefits will, therefore, generally not be
      supported.

o     Proposals related to requests, principally from management, for approval
      of amendments that would alter an issuer's capital structure. As a general
      matter, the Committee will support requests that enhance the rights of
      common shareholders and oppose requests that appear to be unreasonably
      dilutive.

o     Proposals related to requests for approval of amendments to an issuer's
      charter or by-laws. As a general matter, the Committee opposes poison pill
      provisions.

o     Routine proposals related to requests regarding the formalities of
      corporate meetings.

o     Proposals related to proxy issues associated solely with holdings of
      investment company shares. As with other types of companies, the Committee
      believes that a fund's Board of Directors (rather than its shareholders)
      is best-positioned to set fund policy and oversee management. However, the
      Committee opposes granting Boards of Directors authority over certain
      matters, such as changes to a fund's investment objective, that the
      Investment Company Act envisions will be approved directly by
      shareholders.

o     Proposals related to limiting corporate conduct in some manner that
      relates to the shareholder's environmental or social concerns. The
      Committee generally believes that annual shareholder meetings are
      inappropriate forums for discussion of larger social issues, and opposes
      shareholder resolutions "micromanaging" corporate conduct or requesting
      release of information that would not help a shareholder evaluate an
      investment in the corporation as an economic matter. While the Committee
      is generally supportive of proposals to require corporate disclosure of
      matters that seem relevant and material to the economic interests of
      shareholders, the Committee is generally not supportive of proposals to
      require disclosure of corporate matters for other purposes.

      (iv) Potential Material Conflicts of Interest

      Real, potential or apparent conflicts of interest may arise when a
portfolio manager has day-to-day portfolio management responsibilities with
respect to more than one fund or account, including the following:

      Certain investments may be appropriate for the Fund and also for other
clients advised by the Investment. Adviser and its affiliates, including other
client accounts managed by the Fund's portfolio management team. Investment
decisions for the Fund and other clients are made with a view to achieving their
respective investment objectives and after consideration of such factors as
their current holdings, availability of cash for investment and the size of
their investments generally. Frequently, a particular security may be bought or
sold for only one client or in different amounts and at different times for more
than one but less than all clients. Likewise, because clients of the Investment
Adviser and its affiliates may have differing investment strategies, a
particular security may be bought for one or more clients when one or more other
clients are selling the security. The investment results for the Fund may differ
from the results achieved by other clients of the Investment Adviser and its
affiliates and results among clients may differ. In addition, purchases or sales
of the same security may be made for two or more clients on the same day. In
such event, such transactions will be allocated among the clients in a manner



believed by the Investment Adviser and its affiliates to be equitable to each.
The Investment Adviser will not determine allocations based on whether it
receives a performance based fee from the client. In some cases, the allocation
procedure could have an adverse effect on the price or amount of the securities
purchased or sold by the Fund. Purchase and sale orders for the Fund may be
combined with those of other clients of the Investment Adviser and its
affiliates in the interest of achieving the most favorable net results to the
Fund.

      To the extent that the Fund's portfolio management team has
responsibilities for managing accounts in addition to the Fund, a portfolio
manager will need to divide his time and attention among relevant accounts.

      In some cases, a real, potential or apparent conflict may also arise where
(i) the Investment Adviser may have an incentive, such as a performance based
fee, in managing one account and not with respect to other accounts it manages
or (ii) where a member of the Fund's portfolio management team owns an interest
in one fund or account he or she manages and not another.

      (a)(3) As of October 31, 2005:

      Portfolio Manager Compensation

      The portfolio manager compensation program of the Investment Adviser and
its affiliates (collectively, herein "MLIM") is critical to MLIM's ability to
attract and retain the most talented asset management professionals. This
program ensures that compensation is aligned with maximizing investment returns
and it provides a competitive pay opportunity for competitive performance.

      Compensation Program

      The elements of total compensation for MLIM portfolio managers are a fixed
base salary, annual performance-based cash and stock compensation (cash and
stock bonus) and other benefits. MLIM has balanced these components of pay to
provide portfolio managers with a powerful incentive to achieve consistently
superior investment performance. By design, portfolio manager compensation
levels fluctuate -- both up and down -- with the relative investment performance
of the portfolios that they manage.

      Base Salary

      Under the MLIM approach, like that of many asset management firms, base
salaries represent a relatively small portion of a portfolio manager's total
compensation. This approach serves to enhance the motivational value of the
performance-based (and therefore variable) compensation elements of the
compensation program.

      Performance-Based Compensation

      MLIM believes that the best interests of investors are served by
recruiting and retaining exceptional asset management talent and managing their
compensation within a consistent and disciplined framework that emphasizes pay
for performance in the context of an intensely competitive market for talent. To
that end, the portfolio manager incentive compensation is based on a formulaic
compensation program.

      MLIM's formulaic portfolio manager compensation program includes: pre-tax
investment performance over 1-, 3- and 5-year performance periods and a measure
of operational efficiency. Due to the unique nature of the Fund, its performance
is measured based on a Board of Directors-approved metric which considers both
total return performance and dividend performance over time, adjusted for the
cost of leverage. If a portfolio manager's tenure is less than 5-years,
performance periods will reflect time in position. Portfolio managers are
compensated based on the products they manage. A smaller discretionary element



of portfolio manager compensation may include consideration of: financial
results, expense control, profit margins, strategic planning and implementation,
quality of client service, market share, corporate reputation, capital
allocation, compliance and risk control, leadership, workforce diversity,
technology and innovation. MLIM also considers the extent to which individuals
exemplify and foster Merrill Lynch's principles of Client Focus, Respect for the
Individual, Teamwork, Responsible Citizenship and Integrity. All factors are
considered collectively by MLIM management.

      Cash Bonus

      Performance-based compensation is distributed to portfolio managers in a
combination of cash and stock. Typically, the cash bonus, when combined with
base salary, represents more than 60% of total compensation for portfolio
managers.

      Stock Bonus

      A portion of the dollar value of the total annual performance-based bonus
is paid in restricted shares of Merrill Lynch & Co., Inc. (herein, the
"Company") stock. Paying a portion of annual bonuses in stock puts compensation
earned by a portfolio manager for a given year "at risk" based on the Company's
ability to sustain and improve its performance over future periods.

      The ultimate value of stock bonuses is dependent on future Company stock
price performance. As such, the stock bonus aligns each portfolio manager's
financial interests with those of the Company's shareholders and encourages a
balance between short-term goals and long-term strategic objectives. Management
strongly believes that providing a significant portion of competitive
performance-based compensation in stock is in the best interests of investors
and shareholders. This approach ensures that portfolio managers participate as
shareholders in both the "downside risk" and "upside opportunity" of the
Company's performance. Portfolio managers therefore have a direct incentive to
protect the Company's reputation for integrity.

      Other Compensation Programs

      Portfolio managers who meet relative investment performance and expense
management objectives during a performance year are eligible to participate in a
deferred cash program. Awards under this program are in the form of deferred
cash that may be benchmarked to a menu of MLIM mutual funds (including their own
funds) during a five-year vesting period. The deferred cash program aligns the
interests of participating portfolio managers with the investment results of
MLIM products and promotes continuity of successful portfolio management teams.

      Other Benefits

      Portfolio managers are also eligible to participate in broad-based plans
offered generally to Company employees, including broad-based retirement,
401(k), health, and other employee benefit plans.
