A Letter to Shareholders
Dear Shareholder
The new year began on a positive note for most financial markets, continuing the
momentum from the fourth quarter of 2006. At the end of February, however,
global equity markets registered their first significant decline since last
summer. The market jitters were triggered by a significant setback in the
Chinese market and were exacerbated by several concerns, notably a weakening
economy, some disappointing corporate earnings announcements, geopolitical
concerns related to Iran's nuclear program and increasing delinquencies in the
subprime mortgage market. Despite the recent spate of volatility, underlying
stock market fundamentals appear quite sound, supported by a generally good
global economic backdrop, tame inflation, relatively low interest rates and
attractive valuations.
Not unlike the equity market, the bond market also has seen volatility recently
as observers have attempted to interpret mixed economic signals. A bond market
rally late last year reversed early in 2007 as the economic data strengthened.
Prices improved (and yields fell) again in February as equities struggled.
Notably, the Treasury curve remained inverted for much of 2006 and into 2007.
The 30-year Treasury yield stood at 4.68% on February 28, 2007, while the
one-month Treasury offered the highest yield on the curve at 5.24%.
For its part, the Federal Reserve Board (the Fed) has left the target short-term
interest rate on hold at 5.25% since first pausing on August 8, 2006. Although
the central bankers continue to express concern about potential infla tionary
pressures, they also have made reference to signs of economic weakness in their
public statements. Most observers expect the Fed to keep interest rates on hold
for now, but acknowledge that the combination of a mild economic slowdown and
moderating inflation could prompt an interest rate cut later in 2007.
Notwithstanding the volatility along the way, most major market indexes managed
to post positive returns for the annual and semi-annual reporting periods ended
February 28, 2007:

A Discussion With Your Funds' Portfolio Managers
Portfolio activity was centered on maintaining a stable net asset value
and competitive yield amid the prevailing low interest rate environment and
limited new investment opportunities.
Describe the recent market environment relative to municipal bonds.
Long-term bond yields moved slightly lower during the six-month period, as their
prices correspondingly increased. The municipal bond market's strong technical
position allowed long-term tax-exempt bond yields to decline more than taxable
yields.
Bond prices began to improve early in the period as economic growth softened and
the Federal Reserve Board (the Fed) opted to refrain from raising its target
interest rate after 17 consecutive increases since mid-2004. Bond prices found
additional support from moderating oil prices, and by the end of November,
30-year U.S. Treasury bond yields had declined 32 basis points (.32%) to 4.56%.
In December 2006 and January 2007, however, economic releases were generally
stronger than expected. The more positive economic environment, coupled with
year-end profit-taking, helped push bond yields higher (and prices lower). By
the end of January, long-term U.S. Treasury bond yields had risen to 4.93%
before falling again in February as softer economic news, particularly relating
to employment and housing, allowed bond prices to rally once again.
At the end of February 2007, 30-year U.S. Treasury bond yields stood at 4.68%, a
decline of 20 basis points over the past six months. Ten-year U.S. Treasury note
yields declined 18 basis points during the period to 4.56%. Longer-maturity
tax-exempt issues outperformed comparable U.S. Treasury issues as investor
demand outstripped a resurgent new-issue calendar. As reported by Municipal
Market Data, yields on AAA-rated municipal issues maturing in 30 years declined
28 basis points to 3.97%, while yields on 10-year, AAA-rated issues declined
eight basis points to 3.67%.
Investor demand for municipal product remained strong throughout the six-month
period. According to the Investment Company Institute, long-term municipal bond
funds had net new cash flows of over $15 billion in 2006, a 200% increase
compared to flows in 2005. This positive trend continued into 2007, with net
cash flows in January exceeding $2.8 billion. Weekly fund flows, as reported by
AMG Data, also have supported tax-exempt bond prices. Weekly average cash flows
into long-term tax-exempt funds averaged more than $420 million over the past
six months and more than $487 million in February. These flows represent a
considerable improvement from weekly levels of $230 million - $250 million in
the middle of 2006.
New issuance in the municipal market has surged in recent months as
municipalities have rushed to take advantage of low market yields and solid
investor demand. During the six-month period, more than $206 billion in new
long-term tax-exempt bonds was issued, an increase of 19.5% versus the same
period a year ago. During the last three months, more than $115 billion in new
long-term municipal bonds was underwritten, an increase of over 50% compared to
the same period a year earlier. The recent increase in issuance has made the
municipal market's outperformance even more impressive. In the past three
months, we saw more than 10 underwritings that were greater than $750 million in
size. Investor demand has been so strong that these issues were well
oversubscribed and saw their initial offering yields reduced by as much as 10
basis points.
Looking ahead, the tax-exempt bond market's technical position is likely to
remain supportive, leading to continued outperformance relative to taxable
issues. We believe recent stock market volatility and a benign inflationary
environment should foster continued retail demand for municipal product in the
coming months.

BlackRock MuniHoldings Florida Insured Fund
Describe conditions in the State of Florida.
Florida maintains credit ratings of Aa1, AAA and AA+ from Moody's, Standard &
Poor's and Fitch, respectively. The state's consistently strong financial
performance has been the result of a robust service-oriented economy, prudent
budget decisions and a moderate debt profile. Florida's budget for fiscal year
2007 grew 7% to $74 billion and reflects continued spending constraints,
conservative revenue projections and additional deposits to the state's reserve
funds. Florida has adhered to strict budget guidelines in recent history and we
expect that trend to continue, as many of the state's budget practices have been
made into law, including the Constitutional limit on the spending of
non-recurring revenues, which was adopted by voters in November 2006.
Solid economic growth has allowed the state to build revenue reserves to an
estimated $8 billion and to offer its residents some tax relief in the form of
tax credits, tax-free shopping days and the repeal of the intangible tax.
Overall sales tax growth, which has averaged over 8% per year in recent history,
should be sufficient to cover any revenue losses associated with the repeal of
the intangible tax, though no new revenue streams have been created. Spending at
the state level remains dominated by education, with over 50% of the budget
dedicated to primary and secondary education needs. The state also faces
significant additional spending requirements as a result of the recent Class
Size Initiative and an overall desire to increase the quality of public
education in Florida. In addition to education, we expect that population growth
will increase demand on the government to provide more monies for
transportation, public safety, health services and emergency relief.
Overall, Florida's economy continues to outperform on both a national and
regional basis. Job creation has surpassed the national average, leading to low
unemployment and rising personal incomes. The most recent data reflects an
unemployment rate of 3.2%, compared to a national average of 4.4%. These trends,
coupled with a relatively low cost of living, have encouraged migration into
Florida and led to a more diversified demographic base. Although the demands of
a growing population will put pressure on the state's finances, we continue to
believe that Florida is well-positioned given its financial flexibility and
record of proactive management.
How did the Fund perform during the period?
For the six-month period ended February 28, 2007, the Common Shares of BlackRock
MuniHoldings Florida Insured Fund had net annualized yields of 4.94% and 5.29%,
based on a period-end per share net asset value of $14.77 and a per share market
price of $13.81, respectively, and $.362 per share income dividends. Over the
same period, the total investment return on the Fund's Common Shares was +2.77%,
based on a change in per share net asset value from $14.75 to $14.77, and
assuming reinvestment of all distributions.
The Fund's total return, based on net asset value, lagged the +3.11% average
return of the Lipper Florida Municipal Debt Funds category for the six-month
period. (Funds in this Lipper category limit their investment to those
securities exempt from taxation in the State of Florida.) The Fund's
underperformance is attributed largely to its exposure to bonds with
intermediate maturities, which lagged as the yield curve flattened. We have
exposure to these sectors through bonds that have been prerefunded -- thereby
transforming several of our longer-dated issues into intermediate maturities.
Although these bonds have underperformed on a total return basis, they were
acquired in a higher interest rate environment and, as such, contribute
meaningfully to the portfolio's yield. This has allowed the Fund to maintain an
above-average distribution rate compared to its peers. While we have made
efforts to reduce some of the Fund's concentration in prerefunded bonds, the
cycle repeats itself as more bonds are prerefunded and the absolute low level of
interest rates makes them difficult to replace.
As we have noted in the past, the Fund is an insured product within a peer group
that includes funds with the ability to invest in uninsured and non-investment
grade credits. Although the credit spread tightening phenomenon that has
benefited non-investment grade issues has slowed, these lower quality credits
still amply outperformed the high-grade market during the reporting period, and
our lack of exposure detracted from performance versus our more aggressive
peers.
SEMI-ANNUAL REPORTS FEBRUARY 28, 2007 5
A Discussion With Your Funds' Portfolio Managers (continued)
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 distributions, 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 did not alter our mainline strategy -- that is, we continued our efforts to
increase the level of income provided to shareholders while muting the Fund's
net asset value volatility. Having said that, the low absolute level of interest
rates has presented challenges in terms of yield enhancement, as most of the
bonds in the portfolio are booked at higher yields than those currently
available in the market. In general, we made purchases when the market backed up
(that is, rates increased and prices fell) and were sellers in November, after
the market had rallied sharply (that is, rates fell and prices increased).
For the most part, we continued to target premium-coupon bonds in the 20-year to
30-year maturity range whenever they became available. We continued to find the
most attractive risk/reward trade-off here, although the flatness of the yield
curve has made for few compelling opportunities. New municipal issuance in the
State of Florida increased roughly 20% over the six months compared to the same
period a year ago. However, as has been the case for some time, few new issues
met our desired investment characteristics. Much of the supply came in the form
of refinancings, and the majority of the new issues came with coupons below 5%.
Importantly, we remained fully invested throughout the period in an effort to
augment yield.
For the six-month period ended February 28, 2007, the Fund's Auction Market
Preferred Shares had average yields as follows: Series A, 3.54%; Series B,
3.51%; Series C, 3.53%; Series D, 3.50%; and Series E, 3.53%. There was no
material change in the Fundborrowing costs over the course of the period, as the
Fed left the short-term interest rate target unchanged at 5.25%. Although flat
by historical standards, the tax-exempt yield curve maintained a positive slope
throughout the period (particularly compared to the U.S. Treasury curve),
allowing us to borrow at a lower rate than where we invest. This continued to
generate an income benefit to the holders of Common Shares from the leveraging
of Preferred Shares. 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 Shares. For a more complete
explanation of the benefits and risks of leveraging, see page 9 of this report
to shareholders.
How would you characterize the Fund's position at the close of the period?
We ended the period with a slightly defensive stance on interest rates,
reflecting a shift we had made after the market rallied strongly in the fourth
quarter of 2006. We expect to return to a neutral posture, given the flatness of
the yield curve and the fact that the Fed has remained on hold since last
increasing rates in June, instead relying on security selection as the key
driver of performance. While we had expressed some interest in the 10-year to
20-year maturity range in our last report to shareholders, we generally have
remained focused on longer-dated Florida issues, which we believe offer greater
potential for yield enhancement. We intend to exercise patience as we continue
to look for 20-year to 30-year bonds with coupons in the area of 5%.
6 SEMI-ANNUAL REPORTS FEBRUARY 28, 2007
BlackRock MuniHoldings New York Insured Fund, Inc.
Describe conditions in the State of New York.
The State of New York is rated Aa3, AA and AA- by Moody's, Standard & Poor's and
Fitch, respectively, all with stable trends. New York State ranks fifth in both
debt per capita and debt as a percent of personal income, according to Moody's.
It also ranked fifth in per capita income in 2005 (latest), according to the
U.S. Department of Commerce. New York's January 2007 unemployment rate was 4.3%
versus the U.S. national rate of 4.6%. Fiscal year 2006 operations resulted in a
$2 billion surplus and an ending $900 million "rainy day" reserve. The November
2006 financial plan update forecasts a $1.1 billion General Fund surplus in
fiscal year 2007 due to higher-than-expected receipts and spending reductions.
New York's Governor recently proposed a $120.6 billion budget for fiscal year
2008 that increases spending by 6.3%, the largest annual increase since 2000,
and includes $2.8 billion in gap-closing measures, such as $1.2 billion in
healthcare cuts. Key credit issues are cost pressures from Medicaid, pensions
and school aid, as well as the sustainability of growing personal income tax
receipts.
How did the Fund perform during the period?
For the six-month period ended February 28, 2007, the Common Stock of BlackRock
MuniHoldings New York Insured Fund, Inc. had net annualized yields of 4.66% and
5.01%, based on a period-end per share net asset value of $15.13 and a per share
market price of $14.08, respectively, and $0.350 per share income dividends.
Over the same period, the total investment return on the Fund's Common Stock was
+3.65%, based on a change in per share net asset value from $14.96 to $15.13,
and assuming reinvestment of all distributions.
The Fund's total return, based on net asset value, outpaced the +3.29% average
return of the Lipper New York Insured Municipal Debt Funds category for the
six-month period. (Funds in this Lipper category invest primarily in securities
exempt from taxation in New York and insured as to timely payment.) An ongoing
commitment to generating an above average level of distribution income for
shareholders was the primary driver of the Fund's total return performance.
Notably, the Fund maintained an above average yield compared to its Lipper
peers.
The Fund's appetite for incremental yield forced it to seek securities on the
long end of the municipal yield curve, which was among the best-performing
segments in both the municipal market and broader fixed income markets during
the period. This strategy provided a dual benefit for the Fund, allowing it to
pick up additional market yield while also reaping higher total returns thanks
to a sharp rally in longer-dated municipal securities. Out-of-favor coupons
(mainly discounted bonds) and housing bonds were among the portfolio's stronger
performing assets.
Detracting from the Fund's performance was the ongoing effect of a
low-interest-rate environment, wherein issuers of higher coupon bonds pursue
refinancing opportunities and call their outstanding bonds. This trend persisted
during the semi-annual period, and as is characteristic of this scenario,
detracted from overall performance by dampening the distribution income of the
Fund.
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 distributions, 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?
Portfolio activity was centered on maintaining the Fund's relatively high
distribution rate. We invested largely on the long end of the curve, where we
found attractive opportunities to trade the portfolio and generate higher levels
of income. Among our key purchases were the abovementioned lower-coupon and
housing bonds, as well as zero-coupon bonds that included Puerto Rican
zero-coupon bonds. Alternative minimum tax (AMT) issues also were a good source
of incremental yield during the period. We continued to trim some of the
portfolio's short-term investments, specifically shorter-dated prerefunded bonds
and high-coupon, short-call bonds (primarily those with call dates within three
years or less).
SEMI-ANNUAL REPORTS FEBRUARY 28, 2007 7
A Discussion With Your Funds' Portfolio Managers (concluded)
New issuance in the New York municipal market was fairly stagnant, which
continues to present a challenge in terms of diversifying the portfolio and
making up for yield lost to calls of higher-coupon bonds. New issuance was down
9.7% over the six-month period, although the latter three months saw a
significant rise (+70%), which was attributable to a handful of large deals. The
two most noteworthy transactions in which we participated were a $2 billion bond
offering by Hudson Yards Infrastructure (new development project) and a $227
million offering by Carousel Center in Syracuse (existing mall expansion
project). The remaining new issues were primarily in credits where the Fund
already has some exposure, including Long Island Power Authority, or offered
little in the way of diversification.
For the six months ended February 28, 2007, the Fund's Auction Market Preferred
Stock had average yields as follows: Series A, 3.15%; Series B, 3.18%; Series C,
3.24%; Series D, 3.25%; and Series E, 3.20%. There was no material change in the
Fund's borrowing costs over the course of the period, as the Fed left the
short-term interest rate target unchanged at 5.25%. Although flat by historical
standards, the tax-exempt yield curve maintained a positive slope throughout the
period (particularly compared to the U.S. Treasury curve), allowing us to borrow
at a lower rate than where we invest. This continued to generate an income
benefit to the holders of Common Stock from the leveraging of Preferred Stock.
However, 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. For a more complete explanation of the
benefits and risks of leveraging, see page 9 of this report to shareholders.
How would you characterize the Fund's position at the close of the period?
Given a quiet Fed and few new-issue prospects, we are focusing our efforts on
identifying compelling relative value trading opportunities, while continuing to
add higher-yielding securities as occasions arise. At the same time, we await
the new-issue calendar to offer greater prospects for diversification, as well
as income accrual. We continue to expect relative value trading and yield to be
the key drivers of the Fund's future performance and, accordingly, will look to
the long end of the municipal yield curve to supply the most suitable prospects.

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 pay dividends at prevailing short-term interest
rates, and invest 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 of February 28, 2007, BlackRock MuniHoldings Florida Insured Fund and
BlackRock MuniHoldings New York Insured Fund, Inc. had leverage amounts, due to
Auction Market Preferred Shares or Stock of 39.46% and 40.14% of total net
assets, respectively, before the deduction of Preferred Shares or Stock.
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.

24 SEMI-ANNUAL REPORTS FEBRUARY 28, 2007
Notes to Financial Statements (Unaudited)
1. Significant Accounting Policies:
BlackRock MuniHoldings Florida Insured Fund and BlackRock MuniHoldings New York
Insured Fund, Inc. (the "Funds" or individually 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. 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 based upon quoted fair valuations received daily by the
Funds from a 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
due to an unfavorable change in the price of the underlying security or index or
if the counterparty does not perform under the contract. The counterparty for
certain instruments may pledge cash or securities as collateral.
o Financial futures contracts -- Each Fund may purchase or sell financial
futures contracts and options on such financial futures contracts.
Financial futures contracts are contracts for delayed delivery of
securities at a specific future date and at a specific price or yield.
Upon entering into a contract, the Fund deposits and maintains as
collateral such initial margin as required by the exchange on which the
transaction is effected. Pursuant to the contract, the Fund agrees to
receive from or pay to the broker an amount of cash equal to the daily
fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or
losses. When the contract is closed, the Fund records a realized gain or
loss equal to the difference between the value of the contract at the time
it was opened and the value at the time it was closed.
o Options -- 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
SEMI-ANNUAL REPORTS FEBRUARY 28, 2007 25
Notes to Financial Statements (continued)
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.
o Swaps -- Each Fund may enter into swap agreements, which are OTC contracts
in which the Fund and a counterparty agree to make periodic net payments
on a specified notional amount. The net payments can be made for a set
period of time or may be triggered by a predetermined credit event. The
net periodic payments may be based on a fixed or variable interest rate;
the change in market value of a specified security, basket of securities
or index; or the return generated by a security. These periodic payments
received or made by the Fund are recorded in the accompanying Statement of
Operations as realized gains or losses, respectively. Gains or losses are
also realized upon termination of the swap agreements. Swaps are
marked-to-market daily and changes in value are recorded as unrealized
appreciation (depreciation). Risks include changes in the returns of the
underlying instruments, failure of the counterparties to perform under the
contracts' terms and the possible lack of liquidity with respect to the
swap agreements.
(c) Municipal bonds held in trust -- The Funds invest in leveraged residual
certificates ("TOB Residuals") issued by tender option bond trusts ("TOBs"). A
TOB is established by a third party sponsor forming a special purpose entity,
into which a Fund, or an agent on behalf of the Fund, transfers municipal
securities. A TOB typically issues two classes of beneficial interests:
short-term floating rate certificates, which are sold to third party investors,
and residual certificates, which are generally issued to the Fund which made the
transfer or to affiliates of the Fund. Each Fund's transfers of the municipal
securities to a TOB do not qualify for sale treatment under Statement of
Financial Accounting Standards No. 140 "Accounting for Transfers and Servicing
of Financial Assets and Extinguishments of Liabilities," therefore the municipal
securities deposited into a TOB are presented in the Funds' schedules of
investments and the proceeds from the transactions are reported as a liability
for trust certificates of the Funds. Similarly, proceeds from residual
certificates issued to affiliates, if any, from the transaction are included in
the liability for trust certificates. Interest income from the underlying
security is recorded by the Funds on an accrual basis. Interest expense incurred
on the secured borrowing and other expenses related to remarketing,
administration and trustee services to a TOB are reported as expenses of a Fund.
The floating rate certificates have interest rates that generally reset weekly
and their holders have the option to tender certificates to the TOB for
redemption at par at each reset date. The residual interests held by the Funds
include the right of the Funds (1) to cause the holders of a proportional share
of floating rate certificates to tender their certificates at par, and (2) to
transfer a corresponding share of the municipal securities from the TOB to the
Funds. At February 28, 2007, the aggregate value of the underlying municipal
securities transferred to TOBs and the related liability for trust certificates
were:
--------------------------------------------------------------------------------
Range of
Interest Underlying
Liability Rates on the Municipal
for Liability Bonds
Trust for Trust Transferred
Certificates Certificates to TOBs
--------------------------------------------------------------------------------
BlackRock MuniHoldings
Florida Insured Fund ... $44,416,493 3.56% - 3.58% $ 93,022,442
BlackRock MuniHoldings
New York Insured
Fund, Inc. ............. $61,017,240 3.53% - 3.58% $115,393,714
--------------------------------------------------------------------------------
Financial transactions executed through TOBs generally will underperform the
market for fixed rate municipal bonds in a rising interest rate environment, but
tend to outperform the market for fixed rate bonds when interest rates decline
or remain relatively stable. Should short-term interest rates rise, the Funds'
investments in TOB Residuals likely will adversely affect the Funds' investment
income -- net and distributions to shareholders. Fluctuations in the market
value of municipal securities deposited into the TOB may adversely affect the
Funds' net asset value per share. While the Funds' investment policies and
restrictions expressly permit investments in inverse floating rate securities
such as TOB Residuals, they generally do not allow the Funds to borrow money for
purposes of making investments. The Funds' management believes that the Funds'
restrictions on borrowings do not apply to the secured borrowings deemed to have
occurred for accounting purposes.
(d) 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.
(e) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Funds amortize all
premiums and discounts on debt securities.
26 SEMI-ANNUAL REPORTS FEBRUARY 28, 2007
Notes to Financial Statements (continued)
(f) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.
(g) Recent accounting pronouncements -- In July 2006, the Financial Accounting
Standards Board ("FASB") issued Interpretation No. 48 ("FIN 48"), "Accounting
for Uncertainty in Income Taxes -- an interpretation of FASB Statement No. 109."
FIN 48 prescribes the minimum recognition threshold a tax position must meet in
connection with accounting for uncertainties in income tax positions taken or
expected to be taken by an entity including mutual funds before being measured
and recognized in the financial statements. Adoption of FIN 48 is required for
the last net asset value calculation in the first required financial statement
reporting period for fiscal years beginning after December 15, 2006. The impact
on the Funds' financial statements, if any, is currently being assessed.
In September 2006, Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" ("FAS 157"), was issued and is effective for fiscal years
beginning after November 15, 2007. FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair value
measurements. At this time, management is evaluating the implications of FAS 157
and its impact on the Funds' financial statements, if any, has not been
determined.
In addition, in February 2007, FASB issued "Statement of Financial Accounting
Standards No. 159, The Fair Value Option for Financial Assets and Financial
Liabilities" ("FAS 159"), which is effective for fiscal years beginning after
November 15, 2007. Early adoption is permitted as of the beginning of a fiscal
year that begins on or before November 15, 2007, provided the entity also elects
to apply the provisions of FAS 157. FAS 159 permits entities to choose to
measure many financial instruments and certain other items at fair value that
are not currently required to be measured at fair value. FAS 159 also
establishes presentation and disclosure requirements designed to facilitate
comparisons between entities that choose different measurement attributes for
similar types of assets and liabilities. At this time, management is evaluating
the implications of FAS 159 and its impact on the Funds' financial statements,
if any, has not been determined.
2. Investment Advisory Agreement and Transactions with Affiliates:
On September 29, 2006, BlackRock, Inc. ("BlackRock") and Merrill Lynch & Co.,
Inc. ("Merrill Lynch") combined Merrill Lynch's investment management business,
Merrill Lynch Investment Managers, L.P. ("MLIM"), and its affiliates, including
Fund Asset Management, L.P. ("FAM"), with BlackRock, Inc. to create a new
independent company. Merrill Lynch has a 49.8% economic interest and a 45%
voting interest in the combined company and The PNC Financial Services Group,
Inc. has approximately a 34% economic and voting interest. The new company
operates under the BlackRock name and is governed by a board of directors with a
majority of independent members.
The Investment Advisory Agreement between each Fund and BlackRock Advisors, LLC
(the "Manager"), an indirect, wholly owned subsidiary of BlackRock, Inc., became
effective on September 29, 2006. Prior to September 29, 2006, FAM was the Funds'
Manager. The general partner of FAM is Princeton Services, Inc. ("PSI"), an
indirect, wholly owned subsidiary of Merrill Lynch, which is the limited
partner.
The Manager 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 daily net
assets, including proceeds from the issuance of Preferred Shares/Stock. The
Manager (and previously FAM) has agreed to reimburse its management fee by the
amount of management fees each Fund pays to the Manager (and formerly FAM)

BlackRock MuniHoldings Florida Insured Fund

BlackRock MuniHoldings New York Insured Fund, Inc.
The Fund paid a tax-exempt income dividend to holders of Common Stock in the
amount of $.057000 per share on April 2, 2007 to shareholders of record on March
15, 2007.
7. Restatement Information:
During the six months ended February 28, 2007, each Fund determined that the
criteria for sale accounting in Statement of Financial Accounting Standards No.
140 had not been met for certain transfers of municipal bonds, and that these
transfers should have been accounted for as secured borrowings rather than as
sales. Accordingly, the Funds have restated the Statements of Changes in Net
Assets for the year ended August 31, 2006 and certain financial highlights for
each of the five years in the period then ended. The effects of the restatement
were to record the transfers of the municipal bonds as secured borrowings, to
give effect to offsetting changes in realized gain -- net and in the change in
unrealized appreciation/depreciation -- net on the transferred municipal
securities and to give effect to interest on the bonds as interest income and
interest on the secured borrowings as interest expense.

(iv) Potential Material Conflicts of Interest
BlackRock has built a professional working environment, firm-wide
compliance culture and compliance procedures and systems designed to
protect against potential incentives that may favor one account over
another. BlackRock has adopted policies and procedures that address the
allocation of investment opportunities, execution of portfolio
transactions, personal trading by employees and other potential
conflicts of interest that are designed to ensure that all client
accounts are treated equitably over time. Nevertheless, BlackRock
furnishes investment management and advisory services to numerous
clients in addition to the Fund, and BlackRock may, consistent with
applicable law, make investment recommendations to other clients or
accounts (including accounts which are hedge funds or have performance
or higher fees paid to BlackRock, or in which portfolio managers have a
personal interest in the receipt of such fees), which may be the same
as or different from those made to the Fund. In addition, BlackRock,
its affiliates and any officer, director, stockholder or employee may
or may not have an interest in the securities whose purchase and sale
BlackRock recommends to the Fund. BlackRock, or any of its affiliates,
or any officer, director, stockholder, employee or any member of their
families may take different actions than those recommended to the Fund
by BlackRock with respect to the same securities. Moreover, BlackRock
may refrain from rendering any advice or services concerning securities
of companies of which any of BlackRock's (or its affiliates') officers,
directors or employees are directors or officers, or companies as to
which BlackRock or any of its affiliates or the officers, directors and
employees of any of them has any substantial economic interest or
possesses material non-public information. Each portfolio manager also
may manage accounts whose investment strategies may at times be opposed
to the strategy utilized for the Fund. In this connection, it should be
noted that certain portfolio managers currently manage certain accounts
that are subject to performance fees. In addition, certain portfolio
managers assist in managing certain hedge funds and may be entitled to
receive a portion of any incentive fees earned on such funds and a
portion of such incentive fees may be voluntarily or involuntarily
deferred. Additional portfolio managers may in the future manage other
such accounts or funds and may be entitled to receive incentive fees.
As a fiduciary, BlackRock owes a duty of loyalty to its clients and
must treat each client fairly. When BlackRock purchases or sells
securities for more than one account, the trades must be allocated in a
manner consistent with its fiduciary duties. BlackRock attempts to
allocate investments in a fair and equitable manner among client
accounts, with no account receiving preferential treatment. To this
end, BlackRock has adopted a policy that is intended to ensure that
investment opportunities are allocated fairly and equitably among
client accounts over time. This policy also seeks to achieve reasonable
efficiency in client transactions and provide BlackRock with sufficient
flexibility to allocate investments in a manner that is consistent with
the particular investment discipline and client base.
(a)(3) As of February 28, 2007:
Portfolio Manager Compensation
Compensation Program
The elements of total compensation for portfolio managers on
BlackRock's municipal team include a fixed base salary, annual
performance-based cash and stock compensation (cash and stock bonus)
and other benefits. BlackRock has balanced these components of pay to
provide these portfolio managers with a powerful incentive to achieve
consistently superior investment performance. By design, compensation
levels for these portfolio managers fluctuate--both up and down--with
the relative investment performance of the portfolios that they manage.
Base compensation
Like that of many asset management firms, base salaries
represent a relatively small portion of a portfolio manager's total
compensation. This approach serves to enhance the motivational value of
the performance-based (and therefore variable) compensation elements of
the compensation program.
Performance-Based Compensation
BlackRock believes that the best interests of investors are
served by recruiting and retaining exceptional asset management talent
and managing their compensation within a consistent and disciplined
framework that emphasizes pay for performance in the context of an
intensely competitive market for talent. To that end, BlackRock and its
affiliates portfolio manager incentive compensation is based on a
formulaic compensation program. BlackRock's formulaic portfolio manager
compensation program includes: investment performance relative to a
subset of Florida municipal debt funds over 1-, 3- and 5-year
performance periods and a measure of operational efficiency. Portfolio
managers are compensated based on the pre-tax performance of the
products they manage. If a portfolio manager's tenure is less than 5
years, performance periods will reflect time in position. Portfolio
managers are compensated based on products they manage. A discretionary
element of portfolio manager compensation may include consideration of:
financial results, expense control, profit margins, strategic planning
and implementation, quality of client service, market share, corporate
reputation, capital allocation, compliance and risk control,
leadership, workforce diversity, supervision, technology and
innovation. All factors are considered collectively by BlackRock
management.
Long-Term Retention and Incentive Plan (LTIP)
The LTIP is a long-term incentive plan that seeks to reward
certain key employees. The plan provides for the grant of awards that
are expressed as an amount of cash that, if properly vested and subject
to the attainment of certain performance goals, will be settled in cash
and/or in BlackRock, Inc. common stock.
Cash Bonus
Performance-based compensation is distributed to portfolio
managers in a combination of cash and stock. Typically, the cash bonus,
when combined with base salary, represents more than 60% of total
compensation for portfolio managers.
Stock Bonus
A portion of the dollar value of the total annual
performance-based bonus is paid in restricted shares of BlackRock
stock. Paying a portion of annual bonuses in stock puts compensation
earned by a portfolio manager for a given year "at risk" based on the
company's ability to sustain and improve its performance over future
periods. The ultimate value of stock bonuses is dependent on future
BlackRock stock price performance. As such, the stock bonus aligns each
portfolio manager's financial interests with those of the BlackRock
shareholders and encourages a balance between short-term goals and
long-term strategic objectives. Management strongly believes that
providing a significant portion of competitive performance-based
compensation in stock is in the best interests of investors and
shareholders. This approach ensures that portfolio managers participate
as shareholders in both the "downside risk" and "upside opportunity" of
the company's performance. Portfolio managers therefore have a direct
incentive to protect BlackRock's reputation for integrity.
Other Compensation Programs
Portfolio managers who meet relative investment performance
and financial management objectives during a performance year are
eligible to participate in a deferred cash program. Awards under this
program are in the form of deferred cash that may be benchmarked to a
menu of BlackRock mutual funds (including their own fund) during a
five-year vesting period. The deferred cash program aligns the
interests of participating portfolio managers with the investment
results of BlackRock products and promotes continuity of successful
portfolio management teams.
Other Benefits
Portfolio managers are also eligible to participate in
broad-based plans offered generally to employees of BlackRock and its
affiliates, including broad-based retirement, 401(k), health, and other
employee benefit plans.
(a)(4) Beneficial Ownership of Securities. As of February 28, 2007,
neither of Messrs. Sneeden, Jaeckel or O'Connor beneficially
owns any stock issued by the Fund.
Item 9 - Purchases of Equity Securities by Closed-End Management Investment
Company and Affiliated Purchasers - Not Applicable
Item 10 - Submission of Matters to a Vote of Security Holders - Not Applicable
Item 11 - Controls and Procedures
11(a) - The Registrant's principal executive and principal financial officers
have evaluated the Registrant's disclosure controls and procedures,
including internal control over financial reporting, within 90 days of
this filing. Such principal officers have concluded that as of February
28, 2007 the Registrant's disclosure controls and procedures were
effective in design and operation to reasonably ensure that information
required to be disclosed by the Registrant in this Form N-CSR was
recorded, processed, summarized, and reported within the required time
periods, and were sufficient to form the basis of the certifications
required by Rule 30a-2 of the Investment Company Act of 1940, as
amended. Prior to reaching that conclusion, such principal officers had
become aware of matters relating to the Registrant's participation in
certain inverse floater structures that necessitated restatement of
financial information included in Item 1 of this filing. As a result,
management of the Registrant had reevaluated certain disclosure
controls and procedures determined not to be effective, as discussed
more fully below.
Management of the Registrant is responsible for establishing and
maintaining effective internal control over financial reporting. In
fulfilling this responsibility, estimates and judgments by management
are required to assess the expected benefits and related costs of
controls. The Registrant's internal control over financial reporting is
a process designed to provide reasonable assurance regarding the
reliability of financial reporting and the preparation of financial
statements for external purposes in accordance with U.S. generally
accepted accounting principles. Such internal control includes policies
and procedures that provide reasonable assurance regarding prevention
or timely detection of unauthorized acquisition, use or disposition of
a registrant's assets that could have a material effect on the
financial statements.
Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the
risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or
procedures may deteriorate.
A control deficiency exists when the design or operation of a control
does not allow management or employees, in the normal course of
performing their assigned functions, to prevent or detect misstatements
on a timely basis. A significant deficiency is a control deficiency, or
combination of control deficiencies, that adversely affects the
Registrant's ability to initiate, authorize, record, process or report
financial data reliably in accordance with generally accepted
accounting principles such that there is more than a remote likelihood
that a misstatement of the Registrant's annual or interim financial
statements that is more than inconsequential will not be prevented or
detected. A material weakness is a significant deficiency, or
combination of significant deficiencies, that results in more than a
remote likelihood that a material misstatement of the annual or interim
financial statements will not be prevented or detected.
Prior to the filing of the Registrant's Form N-CSR, the Registrant
identified the following control deficiency, that was determined to be
a material weakness, as defined above, in the Registrant's internal
control over financial reporting at February 28, 2007. The Registrant's
controls related to the review and analysis of relevant terms and
conditions of transfers of certain assets pertaining to inverse floater
structures were not operating effectively to appropriately determine
whether the transfers of assets qualified for sale accounting under the
provisions of Statement of Financial Accounting Standards No. 140,
"Accounting for Transfers and Servicing of Financial Assets and
Extinguishments of Liabilities" ("SFAS 140"). As a result, these
controls did not detect that certain transfers were not appropriately
recorded as borrowings. Accordingly, the Registrant's financial
statements as of and for the period ended February 28, 2007, including
prior periods where applicable, were adjusted prior to being issued to
appropriately reflect transfers of such securities as secured
borrowings and to report the related income and expense. These
adjustments had no impact on net assets, net asset value per share or
total return.
Prior to the evaluation of the design and operation of the Registrant's
disclosure controls and procedures at February 28, 2007, the
Registrant's disclosure controls and procedures were modified to
enhance the review and analysis of the relevant terms and conditions of
transfers of securities in connection with inverse floater structures
in light of SFAS 140.
11(b) - There have been no changes in the Registrant's internal control over
financial reporting (as defined in Rule 30a-3(d) under the Investment
Company Act of 1940, as amended) that occurred during the second half
of the Registrant's fiscal year that have materially affected, or are
reasonably likely to materially affect, the Registrant's internal
control over financial reporting. However, as discussed above, as of
February 28, 2007, the Registrant has enhanced controls related to the
application of SFAS 140.

Pursuant to the requirements of the Securities Exchange Act of 1934 and the
