Nuveen Investments Municipal Closed-End Funds
NPI, NPM, NPT

Portfolio Manager's
         COMMENTS

Portfolio manager Paul Brennan reviews key investment strategies and the
six-month performance of these three national Funds. With 16 years of investment
experience, including 10 years at Nuveen, Paul assumed portfolio management
responsibility for NPI, NPM, and NPT in July 2006.


WHAT KEY STRATEGIES WERE USED TO MANAGE THESE FUNDS DURING THE SIX-MONTH
REPORTING PERIOD ENDED APRIL 30, 2007?

During this six-month period, we continued to see a further flattening of the
municipal bond yield curve. In this environment, where the slope of the yield
curve remained a dominant market factor, we continued to emphasize a disciplined
approach to duration1 management and yield curve positioning. As part of this
approach, our purchases for the Funds' portfolios focused mainly on attractively
priced bonds with maturities of 25 years and longer. We believed that bonds in
this part of the curve generally offered more attractive yields, better value
and reward opportunities more commensurate with their risk levels.

Our duration management strategies during this period included the use of
inverse floating rate trusts,2 a type of derivative financial instrument, in all
three of these Funds. The inverse floaters had the dual benefit of increasing
the Funds' distributable income and bringing their durations closer to our
preferred strategic target. Since late 2004, we have also used forward interest
rate swaps and futures contracts, which are additional types of derivative
instruments, as duration management tools in Funds where we believed this would
support our overall investment performance strategies. The goal of this strategy
is to help us manage the Funds' net asset value (NAV) volatility without having
a negative impact on their income streams or common share dividends over the
short term. During this reporting period, we deployed this strategy in NPI and
NPM. NPT did not use this strategy during this period because we believed its
duration was adequately positioned relative to the general market.



1    Duration is a measure of a bond's price sensitivity as interest rates
     change, with longer duration bonds displaying more sensitivity to these
     changes than bonds with shorter durations.

2    An inverse floating rate trust is a financial instrument designed to pay
     long-term tax-exempt interest at a rate that varies inversely with a
     short-term tax-exempt interest rate index. For the Nuveen Funds, the index
     typically used is the Securities Industry and Financial Markets (SIFM)
     Municipal Swap Index (previously referred to as the Bond Market Association
     Index or BMA). Inverse floaters, including those inverse floating rate
     securities in which the Funds invested during the six-month period, are
     further defined within the "Notes to Financial Statements" and "Glossary of
     Terms Used in This Report" sections of this shareholder report.


                                       4



We also continued to put an emphasis on individual credit selection. During this
period, the municipal market saw steady new money issuance as well as a number
of major advance refundings3 and debt restructurings, which provided us with an
increased number of bonds from which to choose. For the six months ended April
30, 2007, municipal issuance nationwide totaled $223.7 billion, up 32% compared
with the six-month period ended April 30, 2006. During the first four months of
2007, supply increased 37% over that of the first four months of 2006--to $135.4
billion--primarily due to a 71% increase in refundings during this period.

Much of the new supply was highly rated and/or insured, and this factor,
combined with the enhanced credit quality resulting from a number of advance
refundings, meant that the Funds' allocations of credits rated AAA generally
increased over this period. We also continued to work to maintain our weightings
of lower credit quality bonds because of their strong performance and support
for the Funds' income streams. For NPT this included participating in the new
offerings of California and New Jersey tobacco bonds that were issued as part of
the advance refunding of older tobacco bonds in these two states. However, as
credit spreads continued to tighten, we generally found fewer attractively
structured lower-rated credit opportunities in the market.

In addition to reinvesting a few bond call proceeds, we selectively sold some of
the Funds' holdings that were nearing redemption in order to generate cash for
purchases. We also took advantage of opportunities to sell bonds that were
purchased when yields were lower and replace them with newer credits that
yielded comparatively more. We continued to redeploy proceeds to bonds that
could help us increase the Funds' income-generating potential, such as credits
with unusual types of coupons, including zero coupon and discount bonds.



3    Advance refundings, also known as pre-refundings or refinancings, occur
     when an issuer sells new bonds and uses the proceeds to fund principal and
     interest payments of older existing bonds. This process often results in
     lower borrowing costs for bond issuers.

For the six months ended April 30, 2007, the cumulative returns on NAV for NPM
and NPT performed in line with the return on the Lehman Brothers Municipal Bond
Index while NPI slightly trailed this measure. All three Funds trailed the
average return for the Funds' Lipper peer group for this period.

Factors that influenced the Funds' returns during this period included duration,
individual security selection, exposure to lower-rated credits, sector
allocations, and advance refunding activity.

As the yield curve continued to flatten over the course of this period,
municipal bonds with maturities of 20 years and longer, as measured by the
Lehman Brothers Municipal Bond Index, performed best, generally outpacing
municipal bonds with shorter maturities. As mentioned earlier, one of our
strategies during this period focused on adding longer bonds to our portfolios.
Overall, this purchase activity and our duration manage-

     and Lipper returns assume reinvestment of dividends.

ment strategies helped to extend the Funds' durations and bring them closer in
line with our preferred strategic range, which was generally beneficial.

During this period, we also continued to employ strategies that we believed
could help to strengthen the future income streams of our portfolios. In
addition to income potential, the Funds' holdings of zero coupon bonds, which we
continued to build, also provided a positive impact on performance for this
period.

With bonds rated BBB or lower and non-rated bonds generally outperforming other
credit quality sectors during this period, all of these Funds benefited from
their weightings in lower-quality credits. The outperformance of these credit
sectors was largely the result of investor demand for the higher yields
typically associated with lower-rated bonds, which drove up their value. NPT had
heavier exposure to subinvestment-grade bonds (those rated BB or lower) than NPI
or NPM, which was especially helpful during this period.

Among the lower-rated holdings making positive contributions to the Funds'
returns for this period were industrial development bonds and health-care
(including hospitals) credits. Lower-rated bonds backed by the 1998 master
tobacco settlement agreement, which comprised approximately 4% of the portfolios
of these Funds as of April 30, 2007, also performed well.

We also continued to see positive contributions from advance refunding activity,
which benefited the Funds through price appreciation and enhanced credit
quality. As previously mentioned, two of the more significant advance refundings
during this period involved BBB rated tobacco bonds issued by California's
Golden State Tobacco Securitization Corporation and New Jersey's Tobacco
Settlement Financing Corporation, which were upgraded to AAA as a result of the
refundings. At the same time, holdings of older, previously pre-refunded bonds
tended to underperform the general municipal market during this period,
particularly those with effective maturities between 5 and 10 years.


                                       7



We should also note that all three of these Funds continued to use financial
leverage to provide opportunities for additional income and total return for
common shareholders. However, this strategy can also add volatility to a Fund's
NAV and share price. Over this period, these two characteristics tended to
offset one another, and the use of leverage was generally a neutral factor in
the total return performance of these three leveraged Funds.


                                       8



                        Dividend and Share Price
                               INFORMATION



As previously noted, these three Funds use leverage to potentially enhance
opportunities for additional income for common shareholders. Although the extent
of this benefit was reduced during this period due to high short-term interest
rates that, in turn, kept the Funds' borrowing costs high, the Funds' use of
leverage continued to provide incremental income. Consequently, the dividends of
NPI, NPM, and NPT remained stable throughout this six-month reporting period.

Due to normal portfolio activity, common shareholders of NPM also received a
capital gains distribution of $0.0172 per share at the end of December 2006.

All of the Funds in this report seek to pay stable dividends at rates that
reflect each Fund's past results and projected future performance. During
certain periods, each Fund may pay dividends at a rate that may be more or less
than the amount of net investment income actually earned by the Fund during the
period. If a Fund has cumulatively earned more than it has paid in dividends, it
holds the excess in reserve as undistributed net investment income (UNII) as
part of the Fund's NAV. Conversely, if a Fund has cumulatively paid dividends in
excess of its earnings, the excess constitutes negative UNII that is likewise
reflected in the Fund's NAV. Each Fund will, over time, pay all of its net
investment income as dividends to shareholders. As of April 30, 2007, NPI and
NPM had positive UNII balances for both financial statement and, based on our
best estimates, tax purposes, while NPT had a positive UNII balance, based on
our best estimates, for tax purposes and a negative UNII balance for financial
statement purposes.

As of April 30, 2007, the Funds' share prices were trading at discounts to their
NAVs as shown in the accompanying chart:

1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

The funds (the "Funds") covered in this report and their corresponding Common
share New York Stock Exchange symbols are Nuveen Premium Income Municipal Fund,
Inc. (NPI), Nuveen Premium Income Municipal Fund 2, Inc. (NPM) and Nuveen
Premium Income Municipal Fund 4, Inc. (NPT). The Funds are registered under the
Investment Company Act of 1940, as amended, as closed-end, diversified
management investment companies.

Each Fund seeks to provide current income exempt from regular federal income tax
by investing primarily in a diversified portfolio of municipal obligations
issued by state and local government authorities or certain U.S. territories.

The following is a summary of significant accounting policies followed by the
Funds in the preparation of their financial statements in accordance with U.S.
generally accepted accounting principles.

Investment Valuation

The prices of municipal bonds in each Fund's investment portfolio are provided
by a pricing service approved by the Fund's Board of Directors. When market
price quotes are not readily available (which is usually the case for municipal
securities), the pricing service may establish fair value based on yields or
prices of municipal bonds of comparable quality, type of issue, coupon, maturity
and rating, indications of value from securities dealers, evaluations of
anticipated cash flows or collateral and general market conditions. Prices of
forward swap contracts are also provided by an independent pricing service
approved by each Fund's Board of Directors. Futures contracts are valued using
the closing settlement price, or, in the absence of such a price, at the mean of
the bid and asked prices. If the pricing service is unable to supply a price for
a municipal bond, forward swap contract or futures contract, each Fund may use a
market price or fair market value quote provided by a major broker/dealer in
such investments. If it is determined that the market price or fair market value
for an investment is unavailable or inappropriate, the Board of Directors of the
Funds, or its designee, may establish a fair value for the investment. Temporary
investments in securities that have variable rate and demand features qualifying
them as short-term investments are valued at amortized cost, which approximates
market value.

Investment Transactions

Investment transactions are recorded on a trade date basis. Realized gains and
losses from transactions are determined on the specific identification method.
Investments purchased on a when-issued/delayed delivery basis may have extended
settlement periods. Any investments so purchased are subject to market
fluctuation during this period. The Funds have instructed the custodian to
segregate assets with a current value at least equal to the amount of the
when-issued/delayed delivery purchase commitments. At April 30, 2007, Premium
Income (NPI), Premium Income 2 (NPM) and Premium Income 4 (NPT) had outstanding
when-issued/delayed delivery purchase commitments of $13,170,785, $5,080,789 and
$3,538,414, respectively.

Investment Income

Interest income, which includes the amortization of premiums and accretion of
discounts for financial reporting purposes, is recorded on an accrual basis.
Investment income also includes paydown gains and losses, if any.

Professional Fees

Professional fees presented in the Statement of Operations consist of legal fees
incurred in the normal course of operations, audit fees, tax consulting fees
and, in some cases, workout expenditures. Workout expenditures are incurred in
an attempt to protect or enhance an investment, or to pursue other claims or
legal actions on behalf of Fund shareholders. Legal fee refund presented on the
Statement of Operations for Premium Income 4 (NPT) reflects a refund of workout
expenditures paid in prior reporting period.

Federal Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to distribute substantially all net investment income and net capital
gains to shareholders and to otherwise comply with the requirements of
Subchapter M of the Internal Revenue Code applicable to regulated investment
companies. Therefore, no federal income tax provision is required. Furthermore,
each Fund intends to satisfy conditions which will enable interest from
municipal securities, which is exempt from regular federal income tax, to retain
such tax-exempt status when distributed to shareholders of the Funds. Net
realized capital gains and ordinary income distributions paid by the Funds are
subject to federal taxation.

Dividends and Distributions to Common Shareholders

Dividends from tax-exempt net investment income are declared monthly. Net
realized capital gains and/or market discount from investment transactions, if
any, are distributed to shareholders not less frequently than annually.
Furthermore, capital gains are distributed only to the extent they exceed
available capital loss carryforwards.


                                       57


Notes to
    FINANCIAL STATEMENTS (Unaudited) (continued)



Distributions to Common shareholders of tax-exempt net investment income, net
realized capital gains and/or market discount, if any, are recorded on the
ex-dividend date. The amount and timing of distributions are determined in
accordance with federal income tax regulations, which may differ from U.S.
generally accepted accounting principles.

Preferred Shares

The Funds have issued and outstanding Preferred shares, $25,000 stated value per
share, as a means of effecting financial leverage. Each Fund's Preferred shares
are issued in more than one Series. The dividend rate paid by the Funds on each
Series is determined every seven days, pursuant to a dutch auction process
overseen by the auction agent, and is payable at the end of each rate period.
The number of Preferred shares outstanding, by Series and in total, for each
Fund is as follows:

================================================================================

Inverse Floating Rate Securities

Each Fund may invest in inverse floating rate securities. An inverse floating
rate security is created by depositing a municipal bond, typically with a fixed
interest rate, into a special purpose trust created by a broker-dealer. In turn,
this trust (a) issues floating rate certificates, in face amounts equal to some
fraction of the deposited bond's par amount or market value, that typically pay
short-term tax-exempt interest rates to third parties, and (b) issues to a
long-term investor (such as one of the Funds) an inverse floating rate
certificate (sometimes referred to as an "inverse floater") that represents all
remaining or residual interest in the trust. The income received by the inverse
floater holder varies inversely with the short-term rate paid to the floating
rate certificates' holders, and in most circumstances the inverse floater holder
bears substantially all of the underlying bond's downside investment risk and
also benefits disproportionately from any potential appreciation of the
underlying bond's value. The price of an inverse floating rate security will be
more volatile than that of the underlying bond because the interest rate is
dependent on not only the fixed coupon rate of the underlying bond but also on
the short-term interest paid on the floating rate certificates, and because the
inverse floating rate security essentially bears the risk of loss of the greater
face value of the underlying bond.

A Fund may purchase an inverse floating rate security in a secondary market
transaction without first owning the underlying bond (referred to as an
"externally-deposited inverse floater"), or instead by first selling a
fixed-rate bond to a broker-dealer for deposit into the special purpose trust
and receiving in turn the residual interest in the trust (referred to as a
"self-deposited inverse floater"). An investment in an externally-deposited
inverse floater is identified in the Portfolio of Investments as an "Inverse
floating rate investment". An investment in a self-deposited inverse floater is
accounted for as a financing transaction in accordance with Statement of
Financial Accounting Standards (SFAS) No. 140 "Accounting for Transfers and
Servicing of Financial Assets and Extinguishment of Liabilities". In such
instances, a fixed-rate bond deposited into a special purpose trust is
identified in the Portfolio of Investments as an "Underlying bond of an inverse
floating rate trust", with the Fund accounting for the short-term floating rate
certificates issued by the trust as "Floating rate obligations" on the Statement
of Assets and Liabilities. In addition, the Fund reflects in Investment Income
the entire earnings of the underlying bond and accounts for the related interest
paid to the holders of the short term floating rate certificates as "Floating
rate obligations interest expense and fees" in the Statement of Operations.

================================================================================

Forward Swap Transactions

The Funds are authorized to invest in certain derivative financial instruments.
Each Fund's use of forward interest rate swap transactions is intended to help
the Fund manage its overall interest rate sensitivity, either shorter or longer,
generally to more closely align the Fund's interest rate sensitivity with that
of the broader municipal market. Forward interest rate swap transactions involve
each Fund's agreement with a counterparty to pay, in the future, a fixed or
variable rate payment in exchange for the counterparty paying the Fund a
variable or fixed rate payment, the accruals for which would begin at a
specified date in the future (the "effective date"). The amount of the payment
obligation is based on the notional amount of the forward swap contract and the
termination date of the swap (which is akin to a bond's maturity). The value of
the Fund's swap commitment would increase or decrease based primarily on the
extent to which long-term interest rates for bonds having a maturity of the
swap's termination date increases or decreases. The Funds may terminate a swap
contract prior to the effective date, at which point a realized gain or loss is
recognized. When a forward swap is terminated, it ordinarily does not involve
the delivery of securities or other underlying assets or principal, but rather
is settled in cash on a net basis. Each Fund intends, but is not obligated, to
terminate its forward swaps before the effective date. Accordingly, the risk of
loss with respect to the swap counterparty on such transactions is limited to
the credit risk associated with a counterparty failing to honor its commitment
to pay any realized gain to the Fund upon termination. To reduce such credit
risk, all counterparties are required to pledge collateral daily (based on the
daily valuation of each swap) on behalf of each Fund with a value approximately
equal to the amount of any unrealized gain above a pre-determined threshold.
Reciprocally, when any of the Funds have an unrealized loss on a swap contract,
the Funds have instructed the custodian to pledge assets of the Funds as
collateral with a value approximately equal to the amount of the unrealized loss
above a pre-determined threshold. Collateral pledges are monitored and
subsequently adjusted if and when the swap valuations fluctuate, either up or
down, by at least the predetermined threshold amount.

Futures Contracts

The Funds are authorized to invest in futures contracts. Upon entering into a
futures contract, a Fund is required to deposit with the broker an amount of
cash or liquid securities equal to a specified percentage of the contract
amount. This is known as the "initial margin." Subsequent payments ("variation
margin") are made or received by a Fund each day, depending on the daily
fluctuation of the value of the contract.

During the period the futures contract is open, changes in the value of the
contract are recognized as an unrealized gain or loss by "marking-to-market" on
a daily basis to reflect the changes in market value of the contract. When the
contract is closed or expired, a Fund records a realized gain or loss equal to
the difference between the value of the contract on the closing date and value
of the contract when originally entered into. Cash held by the broker to cover
initial margin requirements on open futures contracts, if any, is noted in the
Statement of Assets and Liabilities. Additionally, the Statement of Assets and
Liabilities reflects a receivable or payable for the variation margin when
applicable.

Risks of investments in futures contracts include the possible adverse movement
of the securities or indices underlying the contracts, the possibility that
there may not be a liquid secondary market for the contracts and/or that a
change in the value of the contract may not correlate with a change in the value
of the underlying securities or indices.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby certain custodian
fees and expenses are reduced by credits earned on each Fund's cash on deposit
with the bank. Such deposit arrangements are an alternative to overnight
investments.

Indemnifications

Under the Funds' organizational documents, their Officers and Directors are
indemnified against certain liabilities arising out of the performance of their
duties to the Funds. In addition, in the normal course of business, the Funds
enter into contracts that provide general indemnifications to other parties. The
Funds' maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Funds that have not yet
occurred. However, the Funds have not had prior claims or losses pursuant to
these contracts and expect the risk of loss to be remote.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of increases and
decreases in net assets applicable to Common shares from operations during the
reporting period. Actual results may differ from those estimates.

2. FUND SHARES

None of the Funds engaged in transactions in their own shares during the six
months ended April 30, 2007, nor during the fiscal year ended October 31, 2006.

3. INVESTMENT TRANSACTIONS

Purchases and sales (including maturities but excluding short-term investments
and derivative transactions) during the six months ended April 30, 2007, were as

4. INCOME TAX INFORMATION

The following information is presented on an income tax basis. Differences
between amounts for financial statement and federal income tax purposes are
primarily due to the treatment of paydown gains and losses, timing differences
in recognizing taxable market discount, timing differences in recognizing
certain gains and losses on investment transactions and the treatment of
investments in inverse floating rate transactions subject to SFAS No. 140. To
the extent that differences arise that are permanent in nature, such amounts are
reclassified within the capital accounts on the Statement of Assets and
Liabilities presented in the annual report, based on their federal tax basis
treatment; temporary differences do not require reclassification. Temporary and
permanent differences do not impact the net asset values of the Funds.

At April 30, 2007, the cost of investments was as follows:

                                           PREMIUM        PREMIUM        PREMIUM

5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

Each Fund's management fee is separated into two components - a complex-level
component, based on the aggregate amount of all fund assets managed by Nuveen
Asset Management (the "Adviser"), a wholly owned subsidiary of Nuveen
Investments, Inc. ("Nuveen"), and a specific fund-level component, based only on
the amount of assets within each individual fund. This pricing structure enables
Nuveen fund shareholders to benefit from growth in the assets within each
individual fund as well as from growth in the amount of complex-wide assets
managed by the Adviser.

The annual fund-level fee, payable monthly, for each Fund is based upon the
average daily net assets (including net assets attributable to Preferred shares)
of each Fund as follows:

AVERAGE DAILY NET ASSETS
(INCLUDING NET ASSETS
ATTRIBUTABLE TO PREFERRED SHARES)                            FUND-LEVEL FEE RATE
--------------------------------------------------------------------------------
For the first $125 million                                                .4500%
For the next $125 million                                                 .4375
For the next $250 million                                                 .4250
For the next $500 million                                                 .4125
For the next $1 billion                                                   .4000
For the next $3 billion                                                   .3875
For net assets over $5 billion                                            .3750
================================================================================

The annual complex-level fee, payable monthly, which is additive to the
fund-level fee, for all Nuveen sponsored funds in the U.S., is based on the
aggregate amount of total fund assets managed as stated in the table below. As
of April 30, 2007, the complex-level fee rate was .1824%.

COMPLEX-LEVEL ASSETS(1)                                   COMPLEX-LEVEL FEE RATE

For the next $3 billion                                                   .1325
For the next $3 billion                                                   .1250
For the next $5 billion                                                   .1200
For the next $5 billion                                                   .1175
For the next $15 billion                                                  .1150
For Managed Assets over $91 billion(2)                                    .1400
================================================================================
(1)  The complex-level fee component of the management fee for the funds is
     calculated based upon the aggregate Managed Assets ("Managed Assets" means
     the average daily net assets of each fund including assets attributable to
     preferred stock issued by or borrowings by the Nuveen funds) of
     Nuveen-sponsored funds in the U.S.

(2)  With respect to the complex-wide Managed Assets over $91 billion, the fee
     rate or rates that will apply to such assets will be determined at a later
     date. In the unlikely event that complex-wide Managed Assets reach $91
     billion prior to a determination of the complex-level fee rate or rates to
     be applied to Managed Assets in excess of $91 billion, the complex-level
     fee rate for such complex-wide Managed Assets shall be .1400% until such
     time as a different rate or rates is determined.

The management fee compensates the Adviser for overall investment advisory and
administrative services and general office facilities. The Funds pay no
compensation directly to those of its Directors who are affiliated with the
Adviser or to its Officers, all of whom receive remuneration for their services
to the Funds from the Adviser or its affiliates. The Board of Directors has
adopted a deferred compensation plan for independent Directors that enables
Directors to elect to defer receipt of all or a portion of the annual
compensation they are entitled to receive from certain Nuveen advised funds.
Under the plan, deferred amounts are treated as though equal dollar amounts had
been invested in shares of select Nuveen advised funds.

6. NEW ACCOUNTING PRONOUNCEMENTS

Financial Accounting Standards Board Interpretation No. 48

On July 13, 2006, the Financial Accounting Standards Board (FASB) released FASB
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" (FIN 48).
FIN 48 provides guidance for how uncertain tax positions should be recognized,
measured, presented and disclosed in the financial statements. FIN 48 requires
the evaluation of tax positions taken or expected to be taken in the course of
preparing the Funds' tax returns to determine whether the tax positions are
"more-likely-than-not" of being sustained by the applicable tax authority. Tax
positions not deemed to meet the more-likely-than-not threshold would be
recorded as a tax benefit or expense in the current year. Adoption of FIN 48 is
required for fiscal years beginning after December 15, 2006, and is to be
applied to all open tax years as of the effective date. Recent SEC guidance
allows funds to delay implementing FIN 48 into NAV calculations until the fund's
last NAV calculation in the first required financial statement reporting period.
As a result, the Funds must begin to incorporate FIN 48 into their NAV
calculations by October 31, 2007. At this time, management is continuing to
evaluate the implications of FIN 48 and does not expect the adoption of FIN 48
will have a significant impact on the net assets or results of operations of the
Funds.


                                       62





Financial Accounting Standards Board Statement of Financial Accounting Standards
No. 157

In September 2006, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 157, "Fair Value
Measurements." This standard establishes a single authoritative definition of
fair value, sets out a framework for measuring fair value and requires
additional disclosures about fair value measurements. SFAS No. 157 applies to
fair value measurements already required or permitted by existing standards.
SFAS No. 157 is effective for financial statements issued for fiscal years
beginning after November 15, 2007, and interim periods within those fiscal
years. The changes to current generally accepted accounting principles from the
application of this standard relate to the definition of fair value, the methods
used to measure fair value, and the expanded disclosures about fair value
measurements. As of April 30, 2007, the Funds do not believe the adoption of
SFAS No. 157 will impact the financial statement amounts; however, additional
disclosures may be required about the inputs used to develop the measurements
and the effect of certain of the measurements included within the Statement of
Operations for the period.

Agreement and Plan of Merger

On June 20, 2007, Nuveen Investments announced that it had entered into a
definitive Agreement and Plan of Merger ("Merger Agreement") with an investor
group majority-led by Madison Dearborn Partners, LLC. Madison Dearborn Partners,
LLC is a private equity investment firm based in Chicago, Illinois. The investor
group includes affiliates of Merrill Lynch, Wachovia, Citigroup, Deutsche Bank
and Morgan Stanley. It is anticipated that Merrill Lynch and its affiliates will
be indirect "affiliated persons" (as that term is defined in the Investment
Company Act of 1940) of the Funds. Under the terms of the merger, each
outstanding share of Nuveen Investments' common stock (other than dissenting
shares) will be converted into the right to receive a specified amount of cash,
without interest. The merger is expected to be completed by the end of the year,
subject to customary conditions, including obtaining the approval of Nuveen
Investments shareholders, obtaining necessary fund and client consents
sufficient to satisfy the terms of the Merger Agreement, and expiration of
certain regulatory waiting periods. The obligations of Madison Dearborn
Partners, LLC to consummate the merger are not conditioned on its obtaining
financing. The Merger Agreement includes a "go shop" provision through July 19,
2007 during which Nuveen Investments may actively solicit and negotiate
competing takeover proposals.

The consummation of the merger will be deemed to be an "assignment" (as defined
in the 1940 Act) of the investment management agreement between each Fund and
the Adviser, and will result in the automatic termination of each Fund's
agreement. Prior to the consummation of the merger, it is anticipated that the
Board of Directors of each Fund will consider a new investment management
agreement with the Adviser. If approved by the Board, the new agreement would be
presented to the Fund's shareholders for approval, and, if so approved by
shareholders, would take effect upon consummation of the merger. There can be no
assurance that the merger described above will be consummated as contemplated or
that necessary shareholder approvals will be obtained.

Reinvest Automatically
       EASILY AND CONVENIENTLY



Sidebar text: NUVEEN MAKES REINVESTING EASY. A PHONE CALL IS ALL IT TAKES TO SET
UP YOUR REINVESTMENT ACCOUNT.


NUVEEN CLOSED-END FUNDS
DIVIDEND REINVESTMENT PLAN

Your Nuveen Closed-End Fund allows you to conveniently reinvest dividends and/or
capital gains distributions in additional Fund shares.

By choosing to reinvest, you'll be able to invest money regularly and
automatically, and watch your investment grow through the power of tax-free
compounding. Just like dividends or distributions in cash, there may be times
when income or capital gains taxes may be payable on dividends or distributions
that are reinvested.

It is important to note that an automatic reinvestment plan does not ensure a
profit, nor does it protect you against loss in a declining market.

EASY AND CONVENIENT

To make recordkeeping easy and convenient, each month you'll receive a statement
showing your total dividends and distributions, the date of investment, the
shares acquired and the price per share, and the total number of shares you own.

HOW SHARES ARE PURCHASED

The shares you acquire by reinvesting will either be purchased on the open
market or newly issued by the Fund. If the shares are trading at or above net
asset value at the time of valuation, the Fund will issue new shares at the
greater of the net asset value or 95% of the then-current market price. If the
shares are trading at less than net asset value, shares for your account will be
purchased on the open market. If the Plan Agent begins purchasing Fund shares on
the open market while shares are trading below net asset value, but the Fund's
shares subsequently trade at or above their net asset value before the Plan
Agent is able to complete its purchases, the Plan Agent may cease open-market
purchases and may invest the uninvested portion of the distribution in
newly-issued Fund shares at a price equal to the greater of the shares' net
asset value or 95% of the shares' market value on the last business day
immediately prior to the purchase date. Dividends and distributions received to
purchase shares in the open market will normally be invested shortly after the
dividend payment date. No interest will be paid on dividends and distributions
awaiting reinvestment. Because the market price of the shares may increase
before purchases are completed, the average purchase price per share may exceed
the market price at the time of valuation, resulting in the acquisition of fewer
shares than if the dividend or distribution had been paid in shares issued by
the Fund. A pro rata portion of any applicable brokerage commissions on open
market purchases will be paid by Plan participants. These commissions usually
will be lower than those charged on individual transactions.


                                       68



FLEXIBLE

You may change your distribution option or withdraw from the Plan at any time,
should your needs or situation change. Should you withdraw, you can receive a
certificate for all whole shares credited to your reinvestment account and cash
payment for fractional shares, or cash payment for all reinvestment account
shares, less brokerage commissions and a $2.50 service fee.

You can reinvest whether your shares are registered in your name, or in the name
of a brokerage firm, bank, or other nominee. Ask your investment advisor if his
or her firm will participate on your behalf. Participants whose shares are
registered in the name of one firm may not be able to transfer the shares to
another firm and continue to participate in the Plan.

The Fund reserves the right to amend or terminate the Plan at any time. Although
the Fund reserves the right to amend the Plan to include a service charge
payable by the participants, there is no direct service charge to participants
in the Plan at this time.

Glossary of
       TERMS USED IN THIS REPORT



AVERAGE ANNUAL TOTAL RETURN: This is a commonly used method to express an
investment's performance over a particular, usually multi-year time period. It
expresses the return that would have been necessary each year to equal the
investment's actual cumulative performance (including change in NAV or market
price and reinvested dividends and capital gains distributions, if any) over the
time period being considered.

AVERAGE EFFECTIVE MATURITY: The average of the number of years to maturity of
the bonds in a Fund's portfolio, computed by weighting each bond's time to
maturity (the date the security comes due) by the market value of the security.
This figure does not account for the likelihood of prepayments or the exercise
of call provisions unless an escrow account has been established to redeem the
bond before maturity. The market value weighting for an investment in an inverse
floating rate security is the value of the portfolio's residual interest in the
inverse floating rate trust, and does not include the value of the floating rate
securities issued by the trust.

INVERSE FLOATERS: Inverse floating rate securities are created by depositing a
municipal bond, typically with a fixed interest rate, into a special purpose
trust created by a broker-dealer. This trust, in turn, (a) issues floating rate
certificates typically paying short-term tax-exempt interest rates to third
parties in amounts equal to some fraction of the deposited bond's par amount or
market value, and (b) issues an inverse floating rate certificate (sometimes
referred to as an "inverse floater") to an investor (such as a Fund) interested
in gaining investment exposure to a long-term municipal bond. The income
received by the holder of the inverse floater varies inversely with the
short-term rate paid to the floating rate certificates' holders, and in most
circumstances the holder of the inverse floater bears substantially all of the
underlying bond's downside investment risk. The holder of the inverse floater
typically also benefits disproportionately from any potential appreciation of
the underlying bond's value. Hence, an inverse floater essentially represents an
investment in the underlying bond on a leveraged basis.

LEVERAGE-ADJUSTED DURATION: Duration is a measure of the expected period over
which a bond's principal and interest will be paid, and consequently is a
measure of the sensitivity of a bond's or bond Fund's value to changes when
market interest rates change. Generally, the longer a bond's or Fund's duration,
the more the price of the bond or Fund will change as interest rates change.
Leverage-adjusted duration takes into account the leveraging process for a Fund
and therefore is longer than the duration of the Fund's portfolio of bonds.

MARKET YIELD (ALSO KNOWN AS DIVIDEND YIELD OR CURRENT YIELD): An investment's
current annualized dividend divided by its current market price.

NET ASSET VALUE (NAV): A Fund's common share NAV per share is calculated by
subtracting the liabilities of the Fund (including any MuniPreferred shares
issued in order to leverage the Fund) from its total assets and then dividing
the remainder by the number of shares outstanding. Fund NAVs are calculated at
the end of each business day.

TAXABLE-EQUIVALENT YIELD: The yield necessary from a fully taxable investment to
equal, on an after-tax basis, the yield of a municipal bond investment.
