The Benefits and Risks of Leveraging

The Funds utilize leveraging to seek to enhance the yield and net asset value of
their Common Shares or Common Stock. However, these objectives cannot be
achieved in all interest rate environments. To leverage, the Funds issue
Preferred Shares or 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 Shares or
Stock, is paid to Common Shareholders or 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 Shares or Stock. However, in order to
benefit Common Shareholders or 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 Shareholders or 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 Shares or Stock
capitalization of $100 million and the issuance of Preferred Shares or 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 Shares or 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.

In this case, the dividends paid to Preferred Shareholders or Preferred Stock
shareholders are significantly lower than the income earned on the fund's
long-term investments, and therefore the Common Shareholders or 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 Shares
or Stock will be reduced or eliminated completely. At the same time, the market
value on the fund's Common Shares or 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 Shares' or 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 Shares or Stock does not fluctuate. In addition to the
decline in net asset value, the market value of the fund's Common Shares or
Stock may also decline.

As a part of their 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 August 31, 2005, the percentages of
MuniHoldings Florida Insured Fund's and MuniHoldings New York Insured Fund,
Inc.'s total net assets invested in inverse floaters were 5.00% and 6.99%,
respectively, before the deduction of Preferred Shares or Stock.

Since June 2004, the Federal Reserve Board (the Fed) has tirelessly advanced its
interest rate-hiking program, bringing the federal funds rate to 3.5% by August
31 (and to 3.75% on September 20). Economists and investors have struggled to
project the Fed's future moves, vacillating from expectations for an impending
end to monetary tightening to fears that the central bank may increase interest
rates more than is necessary to moderate economic growth and keep inflation in
check. Most recently, the devastation of Hurricane Katrina added a new element
of ambiguity in terms of its impact on the economy and Fed sentiment. Many now
believe the Fed will suspend its interest rate-hiking campaign at some point
this year.

Equity market returns over the past several months have reflected a degree of
investor uncertainty. After a strong finish to 2004, the S&P 500 Index posted
gains in four of the first eight months of 2005. Up to this point, strong
corporate earnings reports and low long-term bond yields have worked in favor of
equities. Factors that pose the greatest risks to stocks include record-high oil
prices, continued interest rate hikes and the possibility for disappointing
earnings for the remainder of the year.

Fixed income markets have fared relatively well in the face of monetary
tightening. As the short end of the yield curve moved in concert with Fed
interest rate hikes, long-term bond yields remained low, perpetuating the yield
curve flattening trend. Because bond prices move in the opposite direction of
yields, the result has been that longer-term bonds have outperformed short-term
bonds. At period end, the spread between two-year and 10-year Treasury yields
was just 18 basis points (.18%).

Financial markets are likely to face continued crosscurrents for the remainder
of 2005, particularly as the economy digests the impact of Hurricane Katrina.
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,

A Discussion With Your Funds' Portfolio Managers

      We continued to focus on increasing the income provided to shareholders
and muting the Funds' net asset value volatility.

Describe the recent market environment relative to municipal bonds.

Over the past year, long-term bond yields generally declined as their prices,
which move in the opposite direction, increased. Most recently, the devastation
of Hurricane Katrina throughout the U.S. Gulf Coast prompted a strong rally in
bond prices. The resultant higher energy prices and expected declines in
consumer confidence and spending pushed longer-term interest rates lower as the
period came to a close.

The Federal Reserve Board (the Fed) continued to raise short-term interest rates
during the period, lifting the federal funds target to 3.50% by period-end (and
to 3.75% on September 20). As short-term interest rates rose in concert with the
Fed interest rate hikes and longer-term bond yields declined, the yield curve
continued to flatten. During the past 12 months, 30-year Treasury yields
declined 68 basis points (.68%) to 4.25% and 10-year Treasury yields fell 11
basis points to 4.02%. By comparison, the two-year Treasury yield rose 143 basis
points to 3.84%. Tax-exempt bond yields exhibited a similar pattern during the
year. The yield on 30-year revenue bonds, as measured by the Bond Buyer Revenue
Bond Index, fell 26 basis points to 4.83%. According to Municipal Market Data,
the yield on AAA-rated issues maturing in 30 years declined 48 basis points to
4.22% while the yield on AAA-rated bonds maturing in 10 years remained unchanged
at 3.50%.

Declining tax-exempt bond yields continued to encourage municipalities to issue
new debt and refund outstanding, higher-couponed issues. Over the past year,
more than $384 billion in new long-term tax-exempt bonds was issued, an increase
of greater than 7.5% versus last year's total of $357 billion. In the past six
months, more than $217 billion in new municipal bonds was underwritten, an
increase of 16.3% versus the same period in 2004. During the first six months of
2005, the volume of refunding issues increased more than 50% compared to
underwritings during the first half of 2004. In August 2005, refunding issuance
increased 18% compared to August 2004 levels. The refunding issues have been
heavily weighted in the 10-year - 20-year maturity range, putting pressure on
intermediate tax-exempt bond yields while supporting longer-term bond prices.

Investor demand for municipal product has remained generally positive. The most
current statistics from the Investment Company Institute indicate that,
year-to-date through July 31, 2005, net new cash flows into long-term municipal
bond funds have exceeded $4.2 billion -- a significant improvement from the
$12.4 billion net outflow seen during the same period in 2004. Weekly figures
for August, as reported by AMG Data Service, pointed to continued positive
flows.

Notably, throughout much of the past six months, high yield tax-exempt bond
funds have been the principal target for the new cash inflows. During August,
these lower-rated/non-rated bond funds received an average of $150 million per
week. The need to invest these cash flows has led to strong demand for
lower-rated issues and a consequent narrowing of credit spreads. Additionally,
an increasing percentage of insured issuance has further reduced the
availability of lower-rated municipal securities, lending more support to higher
prices for these issues.

Municipal bond issues have underperformed their taxable counterparts recently as
Treasury bonds have enjoyed increased demand from foreign governments, which are
unable to benefit from the tax advantage inherent in tax-exempt products. This
underperformance, however, has resulted in attractive tax-exempt bond yield
ratios and, we believe, should continue to attract investors to the municipal
marketplace.

The communities shattered by Hurricane Katrina will require extensive
reconstruction. It is too early to estimate the amount of tax-exempt debt that
may be required to finance these efforts or to assess the overall impact on the
municipal market. However, much of the rebuilding is likely to be funded through
federal loans and grants, and the reconstruction will likely be spread over a
number of years. Consequently, any municipal bond issuance prompted by Katrina
is not likely to disrupt the tax-exempt market in the near future.

MuniHoldings Florida Insured Fund

Describe conditions in the State of Florida.

Florida maintains credit ratings of AA1 from Moody's, AAA from Standard & Poor's
and AA+ from Fitch -- all with stable trends. The favorable ratings are based on
the state's solid economic and financial performance, in addition to moderate
debt and a proactive government that responds to economic downturns faster than
other states. Florida's continued economic strength is bolstered by robust
population growth, which is


4       ANNUAL REPORTS                  AUGUST 31, 2005


attributed to the state's attractive physical environment and favorable business
climate. Although the growth in population has put a strain on services such as
education, transportation and health care, it also has allowed the state to
recover more quickly from sub par economic trends.

Currently, Florida's revenues are higher than budgeted and expenditures remain
under control due to prudent fiscal oversight. The fiscal year 2005 budget was
brought into balance through tight expenditure controls, including outsourcing
work and requiring local governments to pick up costs historically incurred by
the state. To pay for these additional expenses, municipalities imposed
increases to property taxes and/or local sales taxes through voter initiatives.
Given the government's concerns over the high health care costs facing the state
-- roughly $15 billion, or 26% in the upcoming budget -- Governor Jeb Bush has
proposed a partially private health insurance plan. Florida continues to
maintain solid fund balances with consistent General Fund operations. In
addition, the state has a working Capital Reserve Fund and a Budget
Stabilization Fund in excess of $2.4 billion.

How did the Fund perform during the fiscal year?

For the 12-month period ended August 31, 2005, the Common Shares of MuniHoldings
Florida Insured Fund had net annualized yields of 6.52% and 6.34%, based on a
year-end per share net asset value of $15.32 and a per share market price of
$15.75, respectively, and $.999 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +6.49%, based
on a change in per share net asset value from $15.37 to $15.32, and assuming
reinvestment of all distributions.

The Fund's total return, based on net asset value, lagged the +7.86% average
return of the Lipper Florida Municipal Debt Funds category for the 12-month
period. (Funds in this Lipper category limit their investment to those
securities exempt from taxation in the State of Florida.) The Fund's
conservative investment parameters played some role in the underperformance for
the period. Unlike other funds in the Lipper group, the Fund is prohibited from
investing in non-investment grade issues, which outperformed the high-grade
market as credit spreads narrowed during the period. This put the Fund at a
competitive disadvantage.

Three additional factors affected Fund performance during the period. First,
mortgage-refinancing activity continued strong during the year, which prompted
an increased number of prepayment calls on some of the Fund's single-family
housing bonds. This had a negative impact on total return. Second, several
large-coupon bonds in the portfolio were prerefunded in prior periods, as the
issuers took the opportunity to refinance their debt in the low interest rate
environment. This transformed several of our longer-dated bonds into
intermediate-maturity bonds in the one-year - 10-year maturity range -- a sector
that underperformed as the yield curve flattened. Finally, the Fund has an
above-average exposure to higher-coupon bonds priced to a short call. Like the
prerefunded bonds, these shorter-term issues underperformed on a total return
basis. Nevertheless, we continued to hold these bonds to take advantage of their
high acquisition yield, as we would not be able to match their yield in the
current low interest rate environment. Importantly, the Fund continued to
provide a highly competitive yield relative to other closed-end Florida insured
funds. Our long-term commitment to an above-average yield continues to benefit
performance.

For the six-month period ended August 31, 2005, the total investment return on
the Fund's Common Shares was +2.85%, based on a change in per share net asset
value from $15.39 to $15.32, and assuming reinvestment of all distributions.

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 Shares (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 Shares can 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 continued to focus on increasing the income provided to shareholders and
muting the Fund's net asset value volatility. To that end, we sought to sell
bonds in the more volatile 10-year - 15-year maturity range, although this
proved somewhat challenging as the yield curve flattened and bonds in the
intermediate range cheapened relative to longer-dated securities.

In making new purchases, we generally focused on premium-coupon bonds in the
20-year - 25-year maturity range whenever they became available. This is where
we have been able to capture higher yields with reduced volatility. Our
restructuring efforts have been somewhat limited by a modest decline in the
issuance of Florida municipal bonds during the fiscal year and the fact that few
new issues have met our desired investment characteristics. Much of the supply
in the market has come in the form of refinancings, and the majority of the new
issues offered maturities of only 15 years - 20 years and


        ANNUAL REPORTS                  AUGUST 31, 2005                        5


A Discussion With Your Funds' Portfolio Managers (concluded)

yields below 5%. We were not inclined to give up bonds booked in the portfolio
at higher yields in order to take advantage of the new-issue calendar.
Importantly, we remained fully invested throughout the fiscal year in order to
augment the portfolio's yield.

For the six-month period ended August 31, 2005, the Fund's Auction Market
Preferred Shares (AMPS) had average yields as follows: Series A, 1.98%; Series
B, 1.91%; Series C, 1.56%; Series D, 2.06%; and Series E, 1.88%. Continued
short-term interest rate increases by the Fed have boosted the Fund's borrowing
costs throughout the 12-month period. Although we believe the majority of the
Fed's actions have already occurred, additional interest rate hikes are expected
until at least year-end. Nevertheless, the Fund's borrowing costs have remained
historically very low, and the leveraging of Preferred Shares has continued to
generate an income benefit to the holders of Common Shares. However, should the
spread between short-term and long-term tax-exempt rates narrow, the benefits of
leverage will decline and, as a result, reduce the yield on the Fund's Common
Shares. At the end of the period, the Fund's leverage amount, due to AMPS, was
38.64% of total net assets, before the deduction of Preferred Shares. (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?

We would characterize the Fund's position as fairly neutral in terms of interest
rate risk. Currently, we favor bonds with 20-year maturities and 5% coupons. We
believe the Fed will continue to raise short-term interest rates at a measured
pace. While long-term bond yields have been slow to react to the Fed's rate
hikes, we will look for an increase in long-term rates as an opportunity to
pursue higher-coupon bonds (5.25% and above) in the 20 year - 30-year maturity
range.

Vice President and Portfolio Manager

MuniHoldings New York Insured Fund, Inc.

Describe conditions in the State of New York.

The State of New York maintains credit ratings of A1, AA and AA- from Moody's,
Standard and Poor's (S&P) and Fitch, respectively. Moody's assigns a positive
outlook to the state's rating, while Fitch and S&P carry stable outlooks. The
state economy continues to improve and revenue collections are increasing. State
tax collections remain largely dependent on the performance of the financial
sector, but tax receipts for fiscal year 2005 were 15% above the prior fiscal
year. Due to surging tax collections, particularly income taxes, the fiscal year
2005 operating surplus totaled $1.2 billion.

The fiscal year 2006 budget calls for $105 billion in spending and forecasts a
5% increase in tax receipts for the fiscal year. Aided by this revenue growth,
the enacted budget includes most of the governor's original proposals for
closing an estimated $4 billion deficit. However, this does not factor in a
lawsuit won by the Campaign for Fiscal Equity that could add up to $2 billion in
annual state education spending. Crafting balanced budgets beyond fiscal year
2006 will present a challenge given political resistance to additional tax hikes
and cuts in popular programs, as well as pressure from local governments for
pension and Medicaid relief, and new education spending. General fund receipts
are .7% ahead of budget through the first quarter of fiscal year 2006.

The New York economy produced good job growth in 2004, with total non-farm labor
increasing .5% from the prior year. This was the first annual gain since 2000.
Preliminary August 2005 employment (seasonally adjusted) is 1% above the prior
August level. New York ranks fifth-highest among all states in per capita
income. Modest income growth through the remainder of 2005 would boost personal
income tax receipts, which account for roughly 38% of general fund receipts.

How did the Fund perform during the fiscal year?

For the 12-month period ended August 31, 2005, the Common Stock of MuniHoldings
New York Insured Fund, Inc. had net annualized yields of 6.10% and 6.20%, based
on a year-end per share net asset value of $15.54 and a per share market price
of $15.28, respectively, and $.948 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +7.63%, based
on a change in per share net asset value from $15.41 to $15.54, and assuming
reinvestment of all distributions.

The Fund's total return, based on net asset value, lagged the +8.20% average
return of the Lipper New York Insured Municipal Debt Funds category for the
12-month period. (Funds in this Lipper category invest primarily in securities
exempt from taxation in New York and insured as to timely payment.) The modest
underperformance is attributed to the portfolio's slightly shorter-than-average
duration, which we maintained for the bulk of the period based on our belief
that strong economic growth, coupled with a Fed tightening,


6       ANNUAL REPORTS                  AUGUST 31, 2005


would cause long-term bond yields to increase. The defensive positioning was
designed to limit portfolio volatility and protect the Fund's net asset value
from the price impact associated with rising rates. However, long-term rates
actually declined over the course of the year, costing the Fund some capital
appreciation as bond prices correspondingly rose.

The decline in long-term interest rates as short-term interest rates rose also
resulted in a flattening of the yield curve, a phenomenon we sought to
capitalize on by moving into longer-dated securities as opportunities presented
themselves. This strategy helped the Fund's total return as the price of
longer-dated bonds increased. Over the course of the year, we increased the
portfolio's exposure to bonds maturing in 25 years or longer from 46.8% of net
assets to 59.5%.

For the most part, our focus during the period centered on yield rather than
total return. As a result, the Fund was able to gain a competitive yield
advantage versus its New York insured fund peers. While some of our competitors
were forced to cut their dividends as market rates declined, the Fund was able
to maintain an above-average monthly distribution rate.

For the six-month period ended August 31, 2005, the total investment return on
the Fund's Common Stock was +3.44%, based on a change in per share net asset
value from $15.51 to $15.54, and assuming reinvestment of all distributions.

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 can 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?

Throughout the year, we focused on protecting the Fund's net asset value and
providing shareholders with above-average income. To that end, we remained
essentially fully invested and maintained a low turnover rate in order to retain
bonds booked into the portfolio at attractive yields. Whenever possible, we took
opportunities to move further out on the yield curve to pick up additional
yield. Consequently, the Fund's average maturity lengthened from 19.5 years at
the start of the fiscal period to 20.7 years at August 31, 2005.

Recently, there has been little long-maturity new issuance in the New York
municipal market. As issuers are refunding their existing debt, they have tended
to do so with short and intermediate issues. The limited supply of longer-dated
maturities has provided for few trading opportunities. Until market yields
increase or the new-issue calendar produces compelling opportunities, we are
looking to enhance the diversification of the portfolio. For example, we added
bonds insured by several new insurers in the municipal marketplace. These bonds
came with additional yield and should outperform as credit spreads narrow.

For the six-month period ended August 31, 2005, the Fund's Auction Market
Preferred Stock (AMPS) had average yields as follows: Series A, 2.25%; Series B,
2.31%; Series C, 2.32%; Series D, 2.38%; and Series E, 2.37%. Continued
short-term interest rate increases by the Fed have boosted the Fund's borrowing
costs throughout the 12-month period. Although we believe the majority of the
Fed's actions have already occurred, additional rate hikes are expected until at
least year-end. Nevertheless, the Fund's borrowing costs have remained
historically very low, and the leveraging of Preferred Stock has continued to
generate an income benefit to the holders of Common Stock. However, should the
spread between short-term and long-term tax-exempt rates narrow, the benefits of
leverage 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
39.55% 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?

In view of the current risks to the economy and the uncertainty wrought by
Hurricane Katrina, we believe a neutral approach to duration is appropriate. We
maintain our focus on yield generation and are looking for the new-issue market
to pick up and provide more trading opportunities. We continue our efforts to
diversify the portfolio, which we believe will allow us more flexibility to
capitalize on the rapidly changing market and the dislocations caused by the
various market participants.

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 or reduce 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 the Statement of Net Assets, which
comprises part of the financial information included in these reports.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniHoldings Florida Insured Fund and MuniHoldings New York 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. The Funds determine and make available for publication the net asset
value of their Common Stock/Shares on a daily basis. The Funds' Common
Stock/Shares are listed on the New York Stock Exchange under the symbols MFL and
MHN, 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 ("OTC") markets 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/Trustees. Such valuations and procedures are reviewed
periodically by the Board of Directors/Trustees 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/Trustees 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.

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
      Funds as unrealized gains or losses. When the contract is closed, the Fund
      records a realized gain or loss equal to the difference between the value
      of the contract at the time it was opened and the value at the time it was
      closed.

o     Options -- 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.

o     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


26      ANNUAL REPORTS                  AUGUST 31, 2005


Notes to Financial Statements (continued)

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) Reclassification for MuniHoldings New York Insured 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, $781 has been reclassified
between accumulated net realized capital losses and undistributed net investment
income as a result of permanent differences attributable to amortization methods
on fixed income securities. This reclassification has 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 .55% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Stock/Shares. The Investment Adviser has
agreed to reimburse its management fee by the amount of management fees each
Fund pays to FAM indirectly through its investments described below:

In addition, the Investment Adviser has agreed to reimburse its management fee
on the proceeds of Preferred Stock/Shares that exceeds 35% of each Fund's total
net assets. For the year ended August 31, 2005, FAM earned and waived the
following:

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors/ Trustees of MuniHoldings Florida
Insured Fund and MuniHoldings New York Insured Fund, Inc.:

We have audited the accompanying statements of net assets, including the
schedules of investments, of MuniHoldings Florida Insured Fund and MuniHoldings
New York Insured Fund, Inc. (the "Funds"), as of August 31, 2005, and 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 five years in the period then ended.
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.The Funds
are not required to have, nor were we engaged to perform, audits of their
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, 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 August 31, 2005 by correspondence with the custodian and
brokers; where replies were not received from brokers, we performed other
auditing procedures. We believe that our audits provide a reasonable basis for
our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
MuniHoldings Florida Insured Fund and MuniHoldings New York Insured Fund, Inc.
as of August 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 the financial highlights for each of the five years in the period
then ended, in conformity with U.S. generally accepted accounting principles.

Automatic Dividend Reinvestment Plan

The following description of the Funds' 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 Shares or 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 Common Shares or shares of Common Stock
of the Fund. Holders of Common Shares or 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 Common Shares or 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 Common Shares or shares of Common Stock from the Fund
("newly issued shares") or (ii) by purchase of outstanding Common Shares or
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 Shares or Stock is equal to or less than
the market price per Common Share or 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 Common Shares or 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 Common Share or 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.


30      ANNUAL REPORTS                  AUGUST 31, 2005


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.

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 Funds' shares is above the net asset value, participants in the Plan will
receive shares of the Funds 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 Funds do 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 each Fund's shares are trading at a premium
over net asset value, each 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 each 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 Funds reserve 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.

Investment Objectives

NYSE Symbol     MuniHoldings Florida Insured Fund seeks to provide
MFL             shareholders with current income exempt from federal income
                tax. The Fund also seeks to offer shareholders the opportunity
                to own shares, the value of which is exempt from Florida
                intangible personal property tax. The Fund seeks to achieve
                its investment objective by investing primarily in a portfolio
                of long-term, investment grade municipal obligations, the
                interest on which, in the opinion of bond counsel to the
                issuer, is exempt from federal income taxes and which enables
                shares of the Fund to be exempt from Florida intangible
                personal property tax.

         The nature of the services include assurance and related services
         reasonably related to the performance of the audit of financial
         statements not included in Audit Fees.

         (c) Tax Fees -           Fiscal Year Ending August 31, 2005 - $7,000
                                  Fiscal Year Ending August 31, 2004 - $5,610

         The nature of the services include tax compliance, tax advice and tax
         planning.

         (d) All Other Fees -     Fiscal Year Ending August 31, 2005 - $0
                                  Fiscal Year Ending August 31, 2004 - $0

         (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.

         (h) The registrant's audit committee has considered and determined that
         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
         with maintaining the principal accountant's independence.

Item 6 - Schedule of Investments - Not Applicable

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.
