A Letter From the President


Dear Shareholder

After "muddling through" most of 2005, the financial markets saw increased
volatility in January that resulted in a roller coaster of highs and lows for
stocks and a similar ride for bonds. In the end, the major market indexes
managed to post positive returns for the current reporting period:



Total Returns as of January 31, 2006                                  6-month        12-month
                                                                                
U.S. equities (Standard & Poor's 500 Index)                            + 4.68%        +10.38%
Small cap U.S. equities (Russell 2000 Index)                           + 8.50         +18.89
International equities (MSCI Europe, Australasia, Far East Index)      +18.31         +22.76
Fixed income (Lehman Brothers Aggregate Bond Index)                    + 0.84         + 1.80
Tax-exempt fixed income (Lehman Brothers Municipal Bond Index)         + 1.33         + 2.83
High yield bonds (Credit Suisse High Yield Index)                      + 1.40         + 3.59


The Federal Reserve Board (the Fed) advanced its monetary tightening campaign
with eight quarter-point interest rate hikes in 2005 and another on January
31, 2006. This brought the federal funds rate to 4.5%. Notably, Ben Bernanke
replaced Alan Greenspan as Fed chairman in January, a month after the central
bank removed the critical word "measured" from the description of its interest
rate-hiking program. Still, most observers expect another rate increase in
March.

Stocks recorded their third straight year of positive performance in 2005
despite struggling amid rising interest rates, record-high oil prices and a
devastating hurricane season. U.S. equities found support in strong corporate
earnings, low core inflation and healthy company balance sheets. Strength in
the global economy and non-U.S. equity markets helped, as did robust dividend-
distribution, share-buyback and merger-and-acquisition activity. International
markets, in the meantime, continued to benefit from strong economic
statistics, trade surpluses and solid finances.

In the U.S. bond market, short-term interest rates continued to move higher as
longer-term rates advanced more moderately, resulting in a flattening yield
curve. We saw the curve invert temporarily at the end of December and again at
the end of January into early February, with the two-year Treasury note
offering a slightly higher yield than the 10-year note.

Looking ahead, the largest questions center on the Fed's future moves,
the consumer's ability (or inability) to continue spending, the direction
of the U.S. dollar following a year of appreciation and the potential for
continued strong economic and corporate earnings growth. As you consider
how these factors might impact your investments in 2006, we encourage you
to review your goals with your financial advisor and to make portfolio
changes, as needed. For additional insight and timely "food for thought"
for investors, we also invite you to visit Shareholder magazine at

trusting Merrill Lynch Investment Managers with your investment assets,
and we look forward to continuing to serve your investment needs.

SEMI-ANNUAL REPORTS                                            JANUARY 31, 2006



A Discussion With Your Funds' Portfolio Managers


We continued to position the Funds for a flattening municipal yield curve,
which generally benefited performance as longer-term bonds continued to
outperform shorter maturities.


Describe the recent market environment relative to municipal bonds.

During the six-month period, long-term bond yields generally rose as their
prices, which move in the opposite direction, fell. The decline in bond prices
came as commodity prices, especially oil and gold, remained elevated and
investors continued to focus on potential inflationary pressures. Recently, a
rise in national average hourly wage levels has led some economic analysts to
suggest that declines in the U.S. employment rate may result in escalating
wage inflation. These concerns, coupled with moderate economic activity
throughout the six-month period, helped push bond yields higher. At the end of
January, 30-year U.S. Treasury bond yields stood at 4.68% - 21 basis points
higher than six months ago.

The Federal Reserve Board (the Fed) continued to raise short-term interest
rates at each of its meetings during the period, lifting the federal funds
target rate to 4.5% on January 31. Given no indications that the monetary
tightening cycle would be curtailed in early 2006, the yield curve continued
to flatten, with short-term interest rates rising more than longer-term
interest rates. Over the past six months, 10-year U.S. Treasury note yields
rose 25 basis points (.25%) to 4.53% and two-year Treasury yields rose 52
basis points to 4.54%.

Tax-exempt bond yields generally mirrored the movement of their taxable
counterparts throughout most of the six-month period. According to Municipal
Market Data, the yield on AAA-rated issues maturing in 30 years increased 10
basis points to 4.45%, while the yield on AAA-rated issues maturing in 10
years rose 12 basis points to 3.78%. Notably, however, the municipal yield
curve remained steep compared to the Treasury curve.

Over the past six months, $181 billion in new long-term municipal bonds was
underwritten, an 8.8% increase compared to the same period a year ago.
Refunding issues were a prominent component of municipal volume in 2005 as
issuers took advantage of low bond yields and a flattening yield curve to
refinance their outstanding higher-couponed debt. In 2005, refunding activity
of $130.3 billion exceeded 2004 refunding volume by more than 47%. However,
January 2006 brought a dramatic reversal in this trend, with refunding
activity declining to approximately $3.5 billion, down more than 50% from
January 2005. It remains to be seen if this is the beginning of a sustained
decline in re-funding issuance. This is important, as analyst estimates for
new-issue supply in 2006, currently in the $340 billion - $370 billion range,
factor in only modest declines in refunding activity. Should January's trend
continue, new-issue supply in the coming months could be significantly lower.

Investor demand for municipal product remained strong in recent quarters.
According to information from the Investment Company Institute, long-term
tax-exempt bond funds received $5.04 billion in net new monies during 2005.
This represented a sharp reversal from the $13.67 billion outflow experienced
in 2004. Net new cash flows remained strong in the first month of 2006.
Recent statistics from AMG Data Services indicate that average weekly cash
inflows have risen to approximately $300 million, a significant improvement
from the weekly average of $65 million in December.

Looking ahead, the fundamentals for the tax-exempt bond market appear
favorable, and continued positive cash flows are anticipated. Given their
attractive yields relative to comparable U.S. Treasury bonds, and the
prospects for reduced annual issuance in 2006, we believe municipal bonds
could enjoy solid results in the coming months.


MuniHoldings Fund II, Inc.

How did the Fund perform during the period?

For the six-month period ended January 31, 2006, the Common Stock of
MuniHoldings Fund II, Inc. had net annualized yields of 6.31% and 6.33%, based
on a period-end per share net asset value of $14.84 and a per share market
price of $14.80, respectively, and $.472 per share income dividends. Over the
same period, the total investment return on the Fund's Common Stock was
+2.02%, based on a change in per share net asset value from $15.03 to $14.84,
and assuming reinvestment of all distributions.

The Fund's total return, based on net asset value, exceeded the +1.60% average
return of the Lipper General Municipal Debt Funds (Leveraged) category for the
six-month period. (Funds in this Lipper category invest primarily in municipal
debt issues rated in the top four credit-rating categories. These funds can be
leveraged via use of debt, preferred equity and/or reverse repurchase
agreements.)



SEMI-ANNUAL REPORTS                                            JANUARY 31, 2006



The Fund's outperformance can be attributed to a modestly overweighted
exposure to spread product - lower-quality, higher-yielding municipal bonds,
which benefited as credit spreads narrowed during the period. The high yield
municipal market continued to perform well on the back of strong demand, as
investors, looking for better yields in a low interest rate environment,
poured cash into high yield mutual funds. The Fund benefited particularly from
issues in the special tax (land secured), senior living and toll road sectors,
all of which saw gains in an otherwise down market. The Fund also benefited
from price appreciation of its holdings issued by Mississippi's Systems Energy
Resources Inc., a subsidiary of Entergy Corporation, which was downgraded
after Hurricane Katrina struck the U.S. Gulf Coast region. Ironically, the
credit downgrade caused our bonds to appreciate because it made it less
probable that the securities' call feature would be exercised. Of final note,
the Fund's underweight stance in airline bonds was a positive. We had no
exposure to either Delta Airlines Inc. or Northwest Airlines, both of which
declared bankruptcy during the period, in part because of the impact of higher
fuel costs.

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 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 may vary significantly from total investment returns
based on changes in the Fund's net asset value.


What changes were made to the portfolio during the period?

Portfolio activity concentrated on uncovering attractive relative value in the
municipal marketplace. Given the prospect of continued yield curve flattening,
we reduced our exposure to bonds with maturities of 10 years - 18 years while
adding to our holdings in bonds longer than 25 years. We also maintained our
strategy of purchasing bonds of issuers we believed were more likely to
defease their existing debt to help close their budget gaps. When bonds are
defeased, it typically means that the securities are retired at their first
call date, enabling the bonds to appreciate significantly. The State of
California and Commonwealth of Massachusetts are two issuers that have been
aggressive in implementing this strategy. Purchases during the period also
included higher coupon bonds with shorter call dates, which we believed
offered attractive relative yields and the potential for future
outperformance.

For the six months ended January 31, 2006, the average yield for the Fund's
Auction Market Preferred Stock (AMPS) was 2.69% for Series A and 2.66% for
Series B. At this point in the Fed's monetary tightening cycle, interest rate
increases are having an impact on the Fund's borrowing costs. The Fed raised
the short-term interest rate target 125 basis points during the six-month
period. Nevertheless, we were still able to borrow at a lower rate than where
we invest, and this has continued to generate an income benefit to the holders
of Common Stock. Of course, should the spread between short-term and long-term
interest rates narrow, the benefits of leveraging will decline and, as a
result, reduce the yield on the Fund's Common Stock. At the end of the period,
the Fund's leverage amount, due to AMPS, was 34.42% of total net assets,
before the deduction of Preferred 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 Fund's position at the close of the period?

Relative to the broader municipal market, we maintained a neutral level of
interest rate risk but are positioned for the continued flattening of the
yield curve. Having reduced some of our more volatile corporate-backed bonds,
the Fund has a more neutral exposure to high yield spread product. With higher
interest rates and our outlook for slower economic activity, however, we will
be on the lookout for opportunities to slightly increase the Fund's duration.



SEMI-ANNUAL REPORTS                                            JANUARY 31, 2006



A Discussion With Your Funds' Portfolio Managers (concluded)


MuniHoldings New Jersey Insured Fund, Inc.

Describe conditions in the State of New Jersey.

Issuance of long-term municipal bonds in New Jersey totaled approximately
$3.9 billion in the fourth quarter of 2005, a 2.8% decline compared to the
fourth quarter of 2004. For all of 2005, New Jersey municipal volume rose 7.1%
to just over $16 billion on a year-over-year basis, trailing the 13.8%
increase realized in the national municipal market.

New Jersey's economy continued to show signs of recovery, as revenues through
the first half of fiscal year 2006 (that is, the six months ended December 31,
2005), were reported to be favorable to budget. However, the fiscal year 2007
budget, at $28 billion, projects a shortfall of $5 billion - $6 billion. New
Jersey's financial challenges include the adequate funding of the public
pension system, replenishment of the Transportation Trust Fund and compliance
with court-mandated school construction spending. The pension system requires
a minimum $1 billion next year, and a state advisory panel has recommended an
infusion of $12 billion to fix that system. In the meantime, former Governor
Codey's Benefits Review Task Force released its report in December outlining
recommendations for reductions in pension and healthcare costs.

On the political front, New Jersey's November elections resulted in Democrats
retaining control over both the state Senate and Assembly. The Democrats'
gubernatorial candidate, Senator Jon Corzine, also claimed victory as the
state's 54th governor.


How did the Fund perform during the period?

For the six-month period ended January 31, 2006, the Common Stock of
MuniHoldings New Jersey Insured Fund, Inc. had net annualized yields of 5.91%
and 5.81%, based on a period-end per share net asset value of $15.24 and a per
share market price of $15.49, respectively, and $.454 per share income
dividends. Over the same period, the total investment return on the Fund's
Common Stock was +.56%, based on a change in per share net asset value from
$15.62 to $15.24, and assuming reinvestment of all distributions.

The Fund's total return, based on net asset value, trailed the +1.23% average
return of the Lipper New Jersey Municipal Debt Funds category for the six-
month period. (Funds in this Lipper category limit their investment to those
securities exempt from taxation in New Jersey or a city in New Jersey. The
Fund was disadvantaged relative to many of its Lipper peers by its
conservative investment parameters. Specifically, the Fund is limited in its
ability to invest in lower-quality issues, which continued to outperform as
credit spreads (versus higher-quality issues of comparable maturity) tightened
dramatically. Per its investment parameters, 86.7% of the portfolio is
invested in AAA-rated, insured bonds.

The key driver of performance during the period was our yield curve
positioning - specifically, our focus on longer-term bonds, which outperformed
shorter-term issues as the yield curve flattened. This did help performance
somewhat, although not enough to compensate for the larger dynamic in the
municipal market - that being the outperformance of lower-quality issues.

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 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 may vary significantly from total investment returns
based on changes in the Fund's net asset value.


What changes were made to the portfolio during the period?

We saw an unprecedented increase in refinancing activity in 2005, prompted by
the low interest rate environment as well as a dramatic flattening of the
taxable yield curve, which makes the economics of refinancing that much more
appealing for municipal issuers. Thus, a number of the portfolio's more
seasoned issues were advance refunded, prompting our efforts to reallocate the
proceeds. In doing so, we were committed to maintaining a balance between the
income generated by our more seasoned, higher-couponed holdings and the total
return we were trying to achieve with our new investments.



SEMI-ANNUAL REPORTS                                            JANUARY 31, 2006



In our restructuring efforts, we continued to position the Fund for a
flattening yield curve. For most of the period, this involved moving our
exposure further out toward the 20-year - 30-year maturity range. New
purchases in this area of the curve were funded through the sale of some of
those recently prerefunded holdings that had appreciated significantly in
value. When a security is advance refunded, it tends to exhibit risk
characteristics more reflective of a 5-year - 10-year bond, which is not
necessarily our preferred maturity range given the flattening trend. So, we
generally took opportunities to sell those bonds, particularly those with
lower relative yields, and reallocated the proceeds further out.

Toward the end of the period, given the degree of flattening that had been
realized in the municipal yield curve, we began to focus our investments more
in 15-year - 17-year maturity range. We found that we could capture 90% - 93%
of the yield available on the longest bonds (25 years - 30 years) without the
additional risk of extending that far. So, this is really a continuation of
our earlier flattening strategy, with purchases in the 15-year - 17-year range
and still with some concentration in prerefunded bonds for their higher
acquisition yields.

For the six-month period ended January 31, 2006, the Fund's Auction Market
Preferred Stock (AMPS) had average yields as follows: Series A, 2.40%; Series
B, 2.48%; Series C, 2.52%; Series D, 2.43%; and Series E, 2.30%. At this point
in the Fed's monetary tightening cycle, interest rate increases are having an
impact on the Fund's borrowing costs. The Fed raised the short-term interest
rate target 125 basis points during the six-month period. Nevertheless, we
were still able to borrow at a lower rate than where we invest, and this has
continued to generate an income benefit to the holders of Common Stock. Of
course, should the spread between short-term and long-term interest rates
narrow, the benefits of leveraging will decline and, as a result, reduce the
yield on the Fund's Common Stock. At the end of the period, the Fund's
leverage amount, due to AMPS, was 38.66% of total net assets, before the
deduction of Preferred 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 Fund's position at the close of the period?

The municipal bond market had rallied toward period-end. In light of that, we
chose to take a more conservative market posture, including a duration
somewhat shorter than that of our Lipper peers. We believe investors are
struggling to interpret the significance of changes in statements released by
the Fed as well as the uncertainty that accompanies the appointment of a new
Fed chairman. We expect, and the Fed has indicated, that monetary policy will
become increasingly "data dependent" now that the federal funds rate, at 4.5%,
is generally perceived to be in the "neutral" range. Under these circumstances,
we expect to maintain a duration fairly close to that of the Lipper average
(biased toward the short side), at least until rates rise to more attractive
levels.

Looking ahead, with the federal funds rate presently in the neutral range,
it appears we are fairly close to an inflection point, which could result
in a resteepening of the yield curve. To the extent that we do reach that
inflection point, we would likely reconsider our long-standing yield curve
flattening strategy, looking for opportunities to reduce some of the longer-
dated holdings that have outperformed and perhaps positioning the portfolio
for more of a steepening environment.

The Benefits and Risks of Leveraging


The Funds utilize leveraging to seek to enhance the yield and net asset value
of their Common Stock. However, these objectives cannot be achieved in all
interest rate environments. To leverage, each 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 each 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 Funds 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 Funds 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 Funds invest in inverse floaters, the market value of each
Fund's portfolio and the net asset value of each Fund's shares may also be
more volatile than if the Funds did not invest in these securities. As of
January 31, 2006, the percentages of MuniHoldings Fund II, Inc. and
MuniHoldings New Jersey Insured Fund, Inc.'s total net assets invested in
inverse floaters were 4.85% and 5.53%, respectively, before the deduction of
Preferred Stock.

SEMI-ANNUAL REPORTS                                            JANUARY 31, 2006



Notes to Financial Statements


1. Significant Accounting Policies:
MuniHoldings Fund II, Inc. and MuniHoldings New Jersey Insured Fund, Inc. (the
"Funds" or individually as the "Fund") are registered under the Investment
Company Act of 1940, as amended, as non-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. These unaudited financial statements reflect all
adjustments, which are, in the opinion of management, necessary to present a
fair statement of the results for the interim period. All such adjustments are
of a normal, recurring nature. The Funds determine and make available for
publication the net asset value of their Common Stock on a daily basis. The
Funds' Common Stock shares are listed on the New York Stock Exchange under the
symbols MUH and MUJ, respectively. The following is a summary of significant
accounting policies followed by the Funds.

(a) Valuation of investments--Municipal bonds are traded primarily in the over-
the-counter markets ("OTC") and are valued at the last available bid price in
the OTC market or on the basis of values as 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 are
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 sale 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 by quoted fair values received daily by
the Funds' pricing service. 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. 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.

(b) Derivative financial instruments--Each 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--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.

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

Notes to Financial Statements (continued)


* Forward interest rate swaps--Each 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.

(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.


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 .55% of the Fund's average weekly net assets,
including proceeds from the issuance of Preferred Stock for the six months
ended January 31, 2006. The Investment Adviser has agreed to reimburse its
management fee by the amount of management fees each Fund pays to FAM
indirectly through its investment described below:


                                     Investment           Reimbursement

MuniHoldings Fund II, Inc.           Merrill Lynch
                                     Institutional

MuniHoldings New Jersey              CMA New Jersey
   Insured Fund, Inc.                Municipal Money Fund       $10,890


In addition, for MuniHoldings New Jersey Insured Fund, Inc., the Investment
Adviser has agreed to reimburse its management fee based on the proceeds of
Preferred Stock that exceeds 35% of the Fund's total net assets. For the six
months ended January 31, 2006, FAM earned fees of $1,459,725, of which $79,899
was waived.

For the six months ended January 31, 2006, MuniHoldings Fund II, Inc. and
MuniHoldings New Jersey Insured Fund, Inc. reimbursed FAM $2,710 and $5,688,
respectively, for certain accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

In February 2006, ML & Co. and BlackRock, Inc. entered into an agreement to
merge ML & Co.'s investment management business, including FAM, with the
investment management business of BlackRock, Inc. The transaction is expected
to close in the third quarter of 2006.


3. Investments:
Purchases and sales of investments, excluding short-term securities, for the
six months ended January 31, 2006 were as follows:

Each Fund is authorized to issue 200,000,000 shares of stock, including

SEMI-ANNUAL REPORTS                                            JANUARY 31, 2006



Swap Agreements


The Funds may 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. Swap agreements involve the risk that the
party with whom each Fund has entered into the swap will default on its
obligation to pay the Fund and the risk that the Fund will not be able to meet
its obligations to pay the other party to the agreement.



Dividend Policy


The Funds' dividend policy is to distribute all or a portion of its net
investment income to their shareholders on a monthly basis. In order to
provide shareholders with a more stable level of dividend distributions, the
Funds 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
Funds for any particular month may be more or less than the amount of net
investment income earned by the Funds during such month. The Funds' current
accumulated but undistributed net investment income, if any, is disclosed in
