Insured Fund, Inc.


Annual Report
October 31, 2003



MuniYield New Jersey Insured Fund, Inc. seeks to provide
shareholders with as high a level of current income exempt from
Federal income tax and New Jersey personal income taxes as is
consistent with its investment policies and prudent investment
management by investing primarily in a portfolio of long-term
municipal obligations the interest on which, in the opinion of bond
counsel to the issuer, is exempt from Federal income tax and New
Jersey personal income taxes.

This report, including the financial information herein, is
transmitted to shareholders of MuniYield New Jersey Insured Fund,
Inc. for their information. It is not a prospectus. Past performance
results shown in this report should not be considered a
representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred
Stock to provide the Common Stock shareholders with a potentially
higher rate of return. Leverage creates risks for Common Stock
shareholders, including the likelihood of greater volatility of net
asset value and market price of shares of the Common Stock, and the
risk that fluctuations in the short-term dividend rates of the
Preferred Stock may affect the yield to Common Stock shareholders.
Statements and other information herein are as dated and are subject
to change.

MuniYield New Jersey Insured Fund, Inc.


The Benefits and Risks of Leveraging


MuniYield New Jersey Insured Fund, Inc. utilizes leveraging to seek
to enhance the yield and net asset value of its Common Stock.
However, these objectives cannot be achieved in all interest rate
environments. To leverage, the Fund issues Preferred Stock, which
pays dividends at prevailing short-term interest rates, and invests
the proceeds in long-term municipal bonds. The interest earned on
these investments, net of dividends to Preferred Stock, is paid to
Common Stock shareholders in the form of dividends, and the value of
these portfolio holdings is reflected in the per share net asset
value of the Fund's Common Stock. However, in order to benefit
Common Stock shareholders, the yield curve must be positively
sloped; that is, short-term interest rates must be lower than
long-term interest rates. At the same time, a period of generally
declining interest rates will benefit Common Stock shareholders. If
either of these conditions change, then the risks of leveraging will
begin to outweigh the benefits.

To illustrate these concepts, assume a fund's Common Stock
capitalization of $100 million and the issuance of Preferred
Stock for an additional $50 million, creating a total value of
$150 million available for investment in long-term municipal bonds.
If prevailing short-term interest rates are approximately 3% and
long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million
of Preferred Stock based on the lower short-term interest rates. At
the same time, the fund's total portfolio of $150 million earns the
income based on long-term interest rates. Of course, increases in
short-term interest rates would reduce (and even eliminate) the
dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term
investments, and therefore the Common Stock shareholders are the
beneficiaries of the incremental yield. However, if short-term
interest rates rise, narrowing the differential between short-term
and long-term interest rates, the incremental yield pickup on the
Common Stock will be reduced or eliminated completely. At the same
time, the market value of the fund's Common Stock (that is, its
price as listed on the New York Stock Exchange) may, as a result,
decline. Furthermore, if long-term interest rates rise, the Common
Stock's net asset value will reflect the full decline in the price
of the portfolio's investments, since the value of the fund's
Preferred Stock does not fluctuate. In addition to the decline in
net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain
securities whose potential income return is inversely related to
changes in a floating interest rate ("inverse floaters"). In
general, income on inverse floaters will decrease when short-term
interest rates increase and increase when short-term interest rates
decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of
reduced or eliminated interest payments and losses of invested
principal. In addition, inverse floaters have the effect of
providing investment leverage and, as a result, the market value
of such securities will generally be more volatile than that of
fixed-rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the
net asset value of the Fund's shares may also be more volatile than
if the Fund did not invest in these securities. As of October 31,
2003, the percentage of the Fund's total net assets invested in
inverse floaters was 14.00%.


Swap Agreements


The Fund may also invest in swap agreements, which are over-the-
counter contracts in which one party agrees to make periodic
payments based on the change in market value of a specified bond,
basket of bonds, or index in return for periodic payments based on a
fixed or variable interest rate or the change in market value of a
different bond, basket of bonds or index. Swap agreements may be
used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

A Letter From the President


Dear Shareholder

As 2003 draws to a close, it seems appropriate to reflect on what
has been a meaningful year in many respects. We saw the beginning
and the end of all-out war in Iraq, equity market uncertainty turned
to strength and sub par gross domestic product growth of 1.4% in the
first quarter of 2003 grew to an extraordinary 8.2% in the third
quarter. Amid the good news, fixed income investments, which had
become the asset class of choice during the preceding three-year
equity market decline, faced new challenges.

During 2003, municipal bond yields rose and fell in reaction to
geopolitical events, equity market performance, economic activity
and employment figures. By the end of October, long-term municipal
revenue bond yields were slightly higher than they were one year
earlier, at 5.24% as measured by the Bond Buyer Revenue Bond Index.
With many state deficits at record levels, municipalities issued
nearly $400 billion in new long-term tax-exempt bonds during the
12-month period ended October 31, 2003. The availability of bonds,
together with attractive yield ratios relative to U.S. Treasury
issues, made municipal bonds a popular fixed income investment
alternative.

Throughout the year, our portfolio managers continued to work
diligently to deliver on our commitment to provide superior
performance within reasonable expectations for risk and return. This
included striving to outperform our peers and the market indexes.
With that said, remember that the advice and guidance of a skilled
financial advisor often can mean the difference between successful
and unsuccessful investing. A financial professional can help you
choose those investments that will best serve you as you plan for
your financial future.

Finally, I am proud to premiere a new look to our shareholder
communications. Our portfolio manager commentaries have been trimmed
and organized in such a way that you can get the information you
need at a glance, in plain language. Today's markets are confusing
enough. We want to help you put it all in perspective. The report's
new size also allows us certain mailing efficiencies. Any cost
savings in production or postage are passed on to the Fund and,
ultimately, to Fund shareholders.

We thank you for trusting Merrill Lynch Investment Managers with
your investment assets, and we look forward to serving you in the
months and years ahead.



Sincerely,



(Terry K. Glenn)

A Discussion With Your Fund's Portfolio Manager


With interest rates at historically low levels during the period, we
remained focused on generating yield while limiting the Fund's
sensitivity to future interest rate changes.


Describe the market environment relative to municipal bonds during
the fiscal year.

At the end of October, long-term tax-exempt bond yields were
90% - 95% of comparable U.S. Treasury securities, substantially
exceeding their historical average of 85% - 88%. Considering their
tax-free status, this made long-term municipal bonds an attractive
investment alternative during the past 12 months.

Long-term U.S. Treasury bond yields declined throughout most of the
first seven months of the fiscal year, while bond prices--which move
in the opposite direction of yields--rose in response to weak equity
markets, concerns about a growing conflict in Iraq and continued sub
par U.S. economic growth. The Federal Reserve Board continued to
lower short-term interest rates to stimulate business and consumer
economic activity. Bond yields reversed course in July and August,
rising sharply as economic conditions began to improve and as most
analysts agreed the Federal Reserve Board had finished lowering
interest rates. In mid-August, U.S. Treasury bond yields reached
5.45%, their highest level during the period, before again moving
lower and ending the 12-month period at 5.13%, 15 basis points
(.15%) higher than a year earlier.

Long-term tax-exempt bond yields also rose from year-ago levels,
although to a lesser extent than U.S. Treasury bonds. By the end of
October, long-term municipal revenue bond yields stood at 5.24%, a
small increase compared to the previous year. Yields for long-term
Aaa-rated tax-exempt bonds (the highest rated) declined 10 basis
points during the past year. The decline largely reflected
investors' growing demand for high-quality bonds, which provided
valuable stability in an uncertain market.


How did conditions in the state of New Jersey affect the Fund?

New Jersey remained one of the nation's wealthiest states,
characterized by high levels of personal income and large gains in
housing prices. During the fiscal year, the state maintained credit
ratings of AA from Standard & Poor's (S&P), Aa2 from Moody's and AA
from Fitch. While S&P had a stable outlook on the state's credit
condition, Moody's and Fitch maintained a negative outlook.
Nevertheless, the Fund's negligible exposure to uninsured state-
backed bonds meant that the Fund's performance was virtually
unaffected by the potential for credit-rating downgrades.

The state fiscal year closed on June 30, 2003, leaving New Jersey
with another budget shortfall. Several initiatives helped close the
gap, including the securitization of New Jersey's remaining tobacco
settlement and a restructuring of the state's corporate business tax
(CBT). The changes to the CBT resulted in permanent revenue, which
served to enhance New Jersey's long-term financial stability. State
spending was controlled in 2003, remaining comparable to 2002
levels. Although the fiscal year 2004 budget is not yet in balance,
it is only 1.6% higher than the previous year's.

New Jersey's budget shortfalls caused the state to issue more
municipal debt to meet its financial needs. While municipal bond
supply was up throughout the country, New Jersey's rate of issuance
was more than double the national rate of issuance this year. With
such ample supply, New Jersey municipal bonds tended to underperform
their national counterparts.


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

For the year ended October 31, 2003, the Common Stock of MuniYield
New Jersey Insured Fund, Inc., had a net annualized yield of 6.14%,
based on a year-end per share net asset value of $15.25 and $.936
per share income dividends. Over the same period, the total
investment return on the Fund's Common Stock was +7.24%, based on a
change in per share net asset value from $15.14 to $15.25, and
assuming reinvestment of $.936 per share ordinary income dividends.

For the six-month period ended October 31, 2003, the total
investment return on the Fund's Common Stock was +1.21%, based on a
change in per share net asset value from $15.55 to $15.25, and
assuming reinvestment of $.468 per share ordinary income dividends.



MUNIYIELD NEW JERSEY INSURED FUND, INC., OCTOBER 31, 2003



For the six-month period ended October 31, 2003, the Fund's Auction
Market Preferred Stock had an average yield of .84%.

For a description of the Fund's total investment return based on a
change in the per share market value of the Fund's Common Stock (as
measured by the trading price of the Fund's shares on the New York
Stock Exchange), and assuming reinvestment of dividends, please
refer to the Financial Highlights section of the Financial
Statements included in this report. As a closed-end fund, the Fund's
shares may trade in the secondary market at a premium or discount to
the Fund's net asset value. As a result, total investment returns
based on changes in the market value of the Fund's Common Stock can
vary significantly from total investment return based on changes in
the Fund's net asset value.

The Fund's performance, based on net asset value, trailed that of
its comparable Lipper category of New Jersey Municipal Debt Funds,
which had an average return of +8.20% for the 12-month period ended
October 31, 2003. The underperformance can be attributed to two
primary factors. First, as an insured product, the Fund has
conservative investment parameters. Unlike many of the other funds
in the Lipper group, the Fund is precluded from investing in the
more speculative-grade bonds, which happened to be the best
performers in the fixed income marketplace during the period.
Second, the Fund did not employ leverage to the same extent as
several of its peers. Leverage--investing borrowed assets to
generate potentially higher returns--generally benefits shareholders
when interest rates are stable or declining, a phenomenon we
witnessed over the past 12 months.


What changes were made to the portfolio during the period?

To take advantage of continued low interest rates, many issuers
redeemed their bonds prior to maturity. We sought to reinvest the
proceeds from the early calls while at the same time adopting a more
defensive stance for the Fund. Because of the tendency for
reinvestments to lengthen the portfolio's overall duration, we
employed measures to achieve a more desirable average life for the
portfolio. Maintaining the longer duration would have left the Fund
vulnerable to future interest rate changes. Thus, we sold several of
the portfolio's longer-dated securities since the distant maturity
dates made these positions most vulnerable to a rise in interest
rates. We reinvested the proceeds from those sales in high-quality
callable bonds with low volatility characteristics. Late in the
year, as another defensive measure, we initiated a modest hedge
designed to insulate the portfolio from the risk associated with a
rise in interest rates.

The Fund's borrowing costs remained between .75% - 1.25% during the
fiscal year. These attractive funding levels, in combination with a
steep tax-exempt yield curve, generated a significant income benefit
to the Fund's Common Stock shareholders. Further declines in the
Fund's borrowing costs would require significant easing of monetary
policy by the Federal Reserve Board. While such action is not
expected, neither is an imminent increase in short-term interest
rates. We expect short-term borrowing costs to remain near current
attractive levels for the coming months. However, should the spread
between short-term and long-term interest rates narrow, the benefits
of leverage will decline, and as a result, reduce the yield on the
Fund's Common Stock. (For a more complete explanation of the
benefits and risks of leveraging, see page 2 of this report to
shareholders.)


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

The portfolio was positioned for an expected rise in interest rates,
as improving economic news at the close of the period heightened
speculation over whether the Federal Reserve Board would shift its
easing policy. Although the Fund was more defensive than its peers,
we believe this posture should benefit performance if market
sentiment does cause interest rates to rise.

Notes to Financial Statements


1. Significant Accounting Policies:
MuniYield New Jersey Insured Fund, Inc. (the "Fund")is registered
under the Investment Company Act of 1940, as amended, as a non-
diversified, closed-end management investment company. The Fund's
financial statements are prepared in conformity with accounting
principles generally accepted in the United States of America, which
may require the use of management accruals and estimates. The Fund
determines and makes available for publication the net asset value
of its Common Stock on a weekly basis. The Fund's Common Stock is
listed on the New York Stock Exchange under the symbol MJI. The
following is a summary of significant accounting policies followed
by the Fund.

(a) Valuation of investments--Municipal bonds are traded primarily
in the over-the-counter markets and are valued at the last available
bid price in the over-the-counter market or on the basis of yield
equivalents as obtained by the Fund's pricing service from one or
more dealers that make markets in the securities. Financial futures
contracts and options thereon, which are traded on exchanges, are
valued at their closing prices as of the close of such exchanges.
Options written or purchased are valued at the last sale price in
the case of exchange-traded options. In the case of options traded
in the over-the-counter market, valuation is the last asked price
(options written) or the last bid price (options purchased). Swap
agreements are valued by quoted fair values received daily by the
Fund from the counterparty. Short-term investments with a remaining
maturity of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market
quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Board of
Directors of the Fund, including valuations furnished by a pricing
service retained by the Fund, which may utilize a matrix system
for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the
general supervision of the Board of Directors.

(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.

* Financial futures contracts--The 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.

* Options--The Fund is authorized to write covered call options and
purchase 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 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.

* Forward interest rate swaps--The Fund may enter into forward
interest rate swaps. In a forward interest rate swap, the Fund and
the counterparty agree to make periodic net payments on a specified
notional contract amount, commencing on a specified future effective
date, unless terminated earlier. When the agreement is closed, the
Fund records a realized gain or loss in an amount equal to the value
of the agreement.

Notes to Financial Statements (continued)


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

(d) 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 Fund amortizes 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.


2. Investment Advisory Agreement and Transactions with Affiliates:
The Fund has entered into an Investment Advisory Agreement with Fund
Asset Management, L.P. ("FAM"). The general partner of FAM is

limited partner.

FAM 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 an annual rate of .50% of
the Fund's average weekly net assets, including proceeds from the
issuance of Preferred Stock. For the year ended October 31, 2003,
FAM reimbursed the Fund in the amount of $8,589.

For the year ended October 31, 2003, the Fund reimbursed FAM $4,125
for certain accounting services.

October 31, 2003 for Federal income tax purposes was $173,400,829.


4. Stock Transactions:
The Fund is authorized to issue 200,000,000 shares of stock,
including Preferred Stock, par value $.10 per share, all of which
were initially classified as Common Stock. The Board of Directors is
authorized, however, to reclassify any unissued shares of stock
without approval of holders of Common Stock.

Shares issued and outstanding during the years ended October 31,
2003 and October 31, 2002 increased by 13,926 and 90,512,
respectively, as a result of dividend reinvestment.

Preferred Stock
Auction Market Preferred Stock (" AMPS" ) are redeemable shares of
Preferred Stock of the Fund, with a par value of $.05 per share and
a liquidation preference of $25,000 per share, plus accrued and
unpaid dividends, that entitle their holders to receive cash
dividends at an annual rate that may vary for the successive
dividend periods. The yield in effect at October 31, 2003 was .83%.

The Fund pays commissions to certain broker-dealers at the end of
each auction at an annual rate ranging from .25% to .375%,
calculated on the proceeds of each auction. For the year ended
October 31, 2003, Merrill Lynch, Pierce, Fenner & Smith
Incorporated, an affiliate of FAM, earned $86,076 as commissions.

*On October 31, 2003, the Fund had a net capital loss carryforward
of $1,570,772, of which $492,522 expires in 2008 and $1,078,250
expires in 2010. This amount will be available to offset like
amounts of any future taxable gains.

**The difference between book-basis and tax-basis net unrealized
gains is attributable primarily to the tax deferral of losses on
straddles and the difference between book and tax amortization
methods for premiums and discounts on fixed income securities.

MUNIYIELD NEW JERSEY INSURED FUND, INC., OCTOBER 31, 2003



Automatic Dividend Reinvestment Plan


The following description of the Fund's Automatic Dividend
Reinvestment Plan (the "Plan") is sent to you annually as required
by Federal securities laws.

Pursuant to the Fund's Plan, unless a holder of Common Stock
otherwise elects, all dividend and capital gains distributions will
be automatically reinvested by The Bank of New York (the "Plan
Agent"), as agent for shareholders in administering the Plan, in
additional shares of Common Stock of the Fund. Holders of Common
Stock who elect not to participate in the Plan will receive all
distributions in cash paid by check mailed directly to the
shareholder of record (or, if the shares are held in street or
other nominee name then to such nominee) by The Bank of New York,
as dividend paying agent. Such participants may elect not to
participate in the Plan and to receive all distributions of
dividends and capital gains in cash by sending written instructions
to The Bank of New York, as dividend paying agent, at the address
set forth below. Participation in the Plan is completely voluntary
and may be terminated or resumed at any time without penalty by
written notice if received by the Plan Agent not less than ten days
prior to any dividend record date; otherwise such termination will
be effective with respect to any subsequently declared dividend or
distribution.

Whenever the Fund declares an income dividend or capital gains
distribution (collectively referred to as "dividends") payable
either in shares or in cash, non-participants in the Plan will
receive cash and participants in the Plan will receive the
equivalent in shares of Common Stock. The shares will be acquired by
the Plan Agent for the participant's account, depending upon the
circumstances described below, either (i) through receipt of
additional unissued but authorized shares of Common Stock from the
Fund ("newly issued shares") or (ii) by purchase of outstanding
shares of Common Stock on the open market ("open-market purchases")
on the New York Stock Exchange or elsewhere. If on the payment date
for the dividend, the net asset value per share of the Common Stock
is equal to or less than the market price per share of the Common
Stock plus estimated brokerage commissions (such conditions being
referred to herein as "market premium"), the Plan Agent will invest
the dividend amount in newly issued shares on behalf of the
participant. The number of newly issued shares of Common Stock to be
credited to the participant's account will be determined by dividing
the dollar amount of the dividend by the net asset value per share
on the date the shares are issued, provided that the maximum
discount from the then current market price per share on the date of
issuance may not exceed 5%. If on the dividend payment date the net
asset value per share is greater than the market value (such
condition being referred to herein as "market discount"), the Plan
Agent will invest the dividend amount in shares acquired on behalf
of the participant in open-market purchases.

In the event of a market discount on the dividend payment date, the
Plan Agent will have until the last business day before the next
date on which the shares trade on an "ex-dividend" basis or in no
event more than 30 days after the dividend payment date (the "last
purchase date") to invest the dividend amount in shares acquired in
open-market purchases. It is contemplated that the Fund will pay
monthly income dividends. Therefore, the period during which open-
market purchases can be made will exist only from the payment date
on the dividend through the date before the next "ex-dividend" date,
which typically will be approximately ten days. If, before the Plan
Agent has completed its open-market purchases, the market price of a
share of Common Stock exceeds the net asset value per share, the
average per share purchase price paid by the Plan Agent may exceed
the net asset value of the Fund's shares, resulting in the
acquisitions of fewer shares than if the dividend had been paid in
newly issued shares on the dividend payment date. Because of the
foregoing difficulty with respect to open-market purchases, the Plan
provides that if the Plan Agent is unable to invest the full
dividend amount in open-market purchases during the purchase period
or if the market discount shifts to a market premium during the
purchase period, the Plan Agent will cease making open-market
purchases and will invest the uninvested portion of the dividend
amount in newly issued shares at the close of business on the last
purchase date determined by dividing the uninvested portion of the
dividend by the net asset value per share.

The Plan Agent maintains all shareholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account,
including information needed by shareholders for tax records. Shares
in the account of each Plan participant will be held by the Plan
Agent in non-certificated form in the name of the participant, and
each shareholder's proxy will include those shares purchased or
received pursuant to the Plan. The Plan Agent will forward all proxy
solicitation materials to participants and vote proxies for shares
held pursuant to the Plan in accordance with the instructions of the
participants.



MUNIYIELD NEW JERSEY INSURED FUND, INC., OCTOBER 31, 2003



Automatic Dividend Reinvestment Plan (concluded)


In the case of shareholders such as banks, brokers or nominees
which hold shares of others who are the beneficial owners, the Plan
Agent will administer the Plan on the basis of the number of
shares certified from time to time by the record shareholders as
representing the total amount registered in the record shareholder's
name and held for the account of beneficial owners who are to
participate in the Plan.

There will be no brokerage charges with respect to shares issued
directly by the Fund as a result of dividends or capital gains
distributions payable either in shares or in cash. However, each
participant will pay a pro rata share of brokerage commissions
incurred with respect to the Plan Agent's open-market purchases in
connection with the reinvestment of dividends.

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.

Shareholders participating in the Plan may receive benefits not
available to shareholders not participating in the Plan. If the
market price plus commissions of the Fund's shares is above the net
asset value, participants in the Plan will receive shares of the
Fund at less than they could otherwise purchase them and will have
shares with a cash value greater than the value of any cash
distribution they would have received on their shares. If the market
price plus commissions is below the net asset value, participants
will receive distributions in shares with a net asset value greater
than the value of any cash distribution they would have received on
their shares. However, there may be insufficient shares available in
the market to make distributions in shares at prices below the net
asset value. Also, since the Fund does not redeem shares, the price
on resale may be more or less than the net asset value.

The value of shares acquired pursuant to the Plan will generally be
excluded from gross income to the extent that the cash amount
reinvested would be excluded from gross income. If, when the Fund's
shares are trading at a premium over net asset value, the Fund
issues shares pursuant to the Plan that have a greater fair market
value than the amount of cash reinvested, it is possible that all or
a portion of such discount (which may not exceed 5% of the fair
market value of the Fund's shares) could be viewed as a taxable
distribution. If the discount is viewed as a taxable distribution,
it is also possible that the taxable character of this discount
would be allocable to all the shareholders, including shareholders
who do not participate in the Plan. Thus, shareholders who do not
participate in the Plan might be required to report as ordinary
income a portion of their distributions equal to their allocable
share of the discount.

Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the
Plan. There is no direct service charge to participants in the Plan;
however, the Fund reserves the right to amend the Plan to include a
service charge payable by the participants.

All correspondence concerning the Plan should be directed to the
Plan Agent at The Bank of New York, Church Street Station, P.O. Box
11258, New York , NY 10286-1258, Telephone: 800-432-8224.

Dividend Policy


The Fund's dividend policy is to distribute all or a portion of its
net investment income to its shareholders on a monthly basis. In
order to provide shareholders with a more stable level of dividend
distributions, the Fund may at times pay out less than the entire
amount of net investment income earned in any particular month and
may at times in any particular month pay out such accumulated but
undistributed income in addition to net investment income earned in
that month. As a result, the dividends paid by the Fund for any
particular month may be more or less than the amount of net
investment income earned by the Fund during such month. The Fund's
current accumulated but undistributed net investment income, if any,
is disclosed in the Statement of Net Assets, which comprises part of
the financial information included in this report.

Ms. Hodrick has a thorough understanding of generally accepted
accounting principals, financial statements, and internal controls
and procedures for financial reporting. Ms. Hodrick earned a Ph.D.
in economics and has taught courses in finance for over 15 years.
Her M.B.A.-level course centers around the evaluation and analysis
of firms' corporate financial statements. She has also taught in
financial analysts' training programs. Ms. Hodrick has also worked
with several prominent corporations in connection with the analysis
of financial forecasts and projections and analysis of the financial
statements of those companies, serving on the Financial Advisory
Council of one of these major corporations. She has also served as
the Treasurer and Finance Chair of a 501(c)(3) organization. Ms.
Hodrick has published a number of articles in leading economic and
financial journals and is the associate editor of two leading

making loans.  Professor Crum has also served on a number of boards
of directors and has served on the audit committees, and in some

Item 7 - For closed-end funds that contain voting securities in

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 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:

* 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.

* 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.

* 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.

* 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.

* 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.

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

* 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.

* 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.
