Chairman's
LETTER TO SHAREHOLDERS

Photo of: Timothy R. Schwertfeger


Timothy R. Schwertfeger  |  Chairman of the Board

It is with a variety of emotions that I write my last letter to Nuveen Fund
shareholders. For a dozen years, it has been my privilege to communicate
periodically with you through these annual and semi-annual reports about the
performance and uses of your Fund. Over that time, I've tried to emphasize the
central role that quality municipal bonds can play in creating attractive
opportunities for current tax-free income, long-term return and portfolio
diversification. I firmly believe that all our Fund shareholders, working in
conjunction with a trusted financial advisor, have the potential to reach their
financial objectives by using Nuveen Funds as a core component of a
well-balanced portfolio.

As I noted in your Fund's last shareholder report, Nuveen Investments was
acquired in November 2007 by a group led by Madison Dearborn Partners, LLC.
While this event had no impact on the investment objectives, portfolio
management strategies or dividend policies of your Fund, it did provide a
convenient point to begin implementing a long-planned transition in the senior
management team at Nuveen. As a part of this process, I will be leaving the
Board of the Nuveen Funds on June 30, 2008.

In addition, Nuveen and your Fund's Board determined that Fund shareholders
would be best served by having an independent director serve as the new chairman
of the Fund Board. Therefore, I am very excited and pleased to report that I
will be succeeded as chairman of your Nuveen Fund Board by Robert Bremner. A
member of the Board since 1997, Bob is a management consultant and private
investor not affiliated with Nuveen. Over the years, he has played a critical
role on the Fund Board, most recently as the lead independent director, and I
know Bob and the other Board members are determined to maintain the standards
and commitment to quality that you have come to expect from your Nuveen
investment.

Please take the time to review the Portfolio Manager's Comments, the Common
Share Dividend and Share Price Information, and the Performance Overview
sections of this report. All of us are grateful that you have chosen Nuveen
Investments as a partner as you pursue your financial goals, and, on behalf of
Bob Bremner and the other members of your Fund's Board, let me say we look
forward to continuing to earn your trust in the months and years ahead.

Sincerely,

/s/ Timothy R. Schwertfeger

Portfolio Manager's COMMENTS

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

Portfolio manager Paul Brennan reviews key investment strategies and the
six-month performance of these three national Funds. With 19 years of industry
experience, including 17 years at Nuveen, Paul assumed portfolio management
responsibility for the three national Funds in 2006.


WHAT KEY STRATEGIES WERE USED TO MANAGE THESE FUNDS DURING THE SIX-MONTH
REPORTING PERIOD ENDED APRIL 30, 2008?

During this six-month period, the municipal market experienced a great deal of
volatility, as issues related to the sub-prime mortgage industry had an indirect
but important, influence on the municipal market's performance. Other major
factors influencing the municipal market included tighter liquidity stemming
from problems in the credit markets, a flight to quality driven by dislocations
in the financial markets, and continued uncertainty about municipal bond
insurers. We sought to capitalize on this turbulent environment by continuing to
focus on relative value, using a fundamental approach to find undervalued
sectors and individual credits with the potential to perform well over the long
term.

As the market discounted bonds that were out of favor, such as those with lower
credit quality and higher yields, we took advantage of opportunities that we
considered overlooked and undervalued to selectively add these types of bonds to
our portfolios, including bonds rated BBB. In addition, we believed that the
steepening municipal yield curve began to offer better reward opportunities for
purchases made further out on the curve. As a result, many of the additions to
our portfolios emphasized longer maturities. Among the credits we added to the
Funds were uninsured health care bonds, marking the first time in a while that
we found bonds in this sector at attractive levels relative to their credit
quality. We also added exposure to the short end of the yield curve by
purchasing variable rate demand obligations (VRDOs) at very attractive yields.
VRDOs are floating-rate securities that offer interest rates set daily or weekly
based on an index of short-term municipal rates.

To generate cash for purchases, we selectively sold holdings with shorter
durations,(1) including pre-refunded bonds,(2) at attractive prices resulting
from high demand. Selling shorter duration bonds and reinvesting further out on
the yield curve also helped to






Discussions of specific investments are for illustrative purposes only and are
not intended as recommendations of individual investments. The views expressed
in this commentary represent those of the portfolio manager as of the date of
this report and are subject to change at any time, based on market conditions
and other factors. The Funds disclaim any obligation to advise shareholders of
such changes.


(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)  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.


                                       4



improve the Funds' overall call protection profiles. In addition, a number of
our new purchases were funded with cash generated by bond redemptions.

As noted earlier, over the course of the entire reporting period, we saw the
municipal yield curve steepen, as municipal bond interest rates at the short end
of the curve declined while longer-term rates rose. In this environment, we
continued to emphasize a disciplined approach to duration management. As part of
this strategy, we use inverse floating rate securities,(3) a type of derivative
financial instrument, in all three of these Funds. Inverse floaters typically
provide the dual benefit of lengthening the Funds' durations to be closer to our
strategic target and enhancing their income- generation capabilities. Going into
this period, NPI, NPM and NPT also used forward interest rate swaps. The goal of
this strategy was to help us manage the common share net asset value (NAV)
volatility of these Funds without having a negative impact on their income
streams or common share dividends over the short term. During this period, we
removed the forward interest rate swaps from NPM and NPT.

HOW DID THE FUNDS PERFORM?

Individual results for these Funds, as well as relevant index and peer group
information, are presented in the accompanying table.

(3)  An inverse floating rate security 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 this reporting period, are
     further defined within the Notes to Financial Statements and Glossary of
     Terms Used in This Report sections of this shareholder report.

(4)  The Lipper General Leveraged Municipal Debt Funds Average is calculated
     using the returns of all closed-end funds in this category for each period
     as follows: six months, 54; 1 year, 54; 5 years, 52; and 10 years, 38. Fund
     and Lipper returns assume reinvestment of dividends.

(5)  The Lehman Brothers Municipal Bond Index is an unleveraged, unmanaged
     national index comprising a broad range of investment-grade municipal
     bonds. Results for the Lehman index do not reflect any expenses.


                                       5



For the six months ended April 30, 2008, the cumulative returns on NAV for all
three of the Funds in this report underperformed the return on the Lehman
Brothers Municipal Bond Index. At the same time, the six-month returns for all
three Funds outperformed the average return for their Lipper peer group.

One of the major factors impacting the six-month performance of these Funds in
relation to that of the unleveraged Lehman Brothers Municipal Bond Index was the
use of financial leverage. While leverage provides opportunities for additional
income and total returns for common shareholders, the benefits of leveraging are
tied in part to the short-term rates that leveraged Funds pay their preferred
shareholders. During this period, as the yields on longer-term bonds rose and
their prices correspondingly fell, declining valuations had a negative effect on
performance that was magnified by the use of leverage. In addition, the Funds'
borrowing costs remained relatively high, negatively impacting their total
returns. (See Recent Developments in the Auction Rate Preferred Markets at the
end of this commentary.)

Other key factors that influenced the Funds' returns included yield curve and
duration positioning, the use of derivatives, credit exposure and sector
allocations, and holdings of bonds backed by certain municipal bond insurers.

During this six-month period, bonds in the Lehman Brothers Municipal Bond Index
with maturities of eight years or less, especially those maturing in two to six
years, benefited the most from changes in the interest rate environment. As a
result, these shorter maturity bonds generally outperformed credits with longer
maturities. Bonds having the longest maturities (22 years and longer) posted the
worst returns. As previously noted, one of our strategies during this period
focused on adding longer maturity bonds to our portfolios as the yield curve
steepened, based on our belief that these bonds offer good long-term potential.
This purchase activity helped to extend the Funds' durations, which generally
had a negative impact on performance during these past six months.

As mentioned earlier, all three Funds used forward interest rate swaps. In these
Funds, which had durations that exceeded our strategic target, the interest rate
swaps were used to synthetically shorten duration. During this period, in
contrast to historical trends, the U.S. Treasury market and the municipal market
moved in the opposite


                                       6



directions. As municipal market performance lagged the significant gains made by
Treasuries, these derivatives performed poorly, hurting the performance of the
three Funds. In addition, the inverse floaters used by all three of these Funds
had a negative on performance. This resulted from the fact that the inverse
floaters effectively increased the Funds' exposure to longer maturity bonds
during a period when shorter maturities were in favor in the market. However,
the inverse floaters also benefited the Funds by helping to support their income
streams.

As credit spreads widened, bonds rated BBB or below posted poor returns. The
underperformance of the lower credit quality sector was largely the result of
risk- averse investors' flight to quality as disruptions in the financial and
housing markets deepened. As of April 30, 2008, the Funds' holdings of bonds
rated BBB ranged from approximately 7% in NPT to 12% in NPM. The Funds'
allocations to this credit quality sector were generally higher than that of the
Lehman Brothers Municipal Bond Index, and the negative impact of this greater
exposure to credit risk accounted for some of the performance differential
between these Funds and the index.

In general, bonds that carried any credit risk, regardless of sector, tended to
perform poorly. Revenue bonds as a whole and especially the industrial
development and health care sectors that had ranked among the top performers in
the Lehman Brothers Municipal Bond Index over the past few years, underperformed
the general municipal market. The housing sector also performed poorly, as did
lower-rated bonds backed by the 1998 master tobacco settlement agreement.

Sectors of the market that generally contributed to the Funds' performances
included general obligation bonds, water and sewer, electric utilities, and
special tax issues. Pre-refunded bonds performed exceptionally well, due
primarily to their shorter effective maturities and higher credit quality.

Another factor that had an impact on the performance of these Funds was their
position in bonds backed by certain municipal insurers. As concern increased
about the balance sheets of municipal bond insurers, prices on bonds insured by
these companies declined, detracting from the performance of the Funds. On the
whole, the


                                       7



holdings of all of our Funds continued to be well diversified not only between
insured and uninsured bonds, but also within the insured bond category.

RECENT DEVELOPMENTS REGARDING BOND INSURANCE COMPANIES

The portfolios of investments reflect the ratings on certain bonds insured by
AMBAC, CIFG, FGIC, MBIA and XLCA as of April 30, 2008. During the period covered
by this report, at least one rating agency reduced the rating for AMBAC-insured
and MBIA-insured bonds to AA and at least one rating agency further reduced the
ratings for FGIC-insured and XLCA-insured bonds to BB. Subsequent to April 30,
2008, and at the time this report was prepared, at least one rating agency
further reduced the rating for CIFG-insured bonds to BB and MBIA-insured bonds
to A. As of April 30, 2008, at least one rating agency has placed XLCA-insured
bonds on "negative credit watch" and one or more rating agencies have placed
each of these insurers on "negative outlook", which may presage one or more
rating reductions for such insurer or insurers in the future. If one or more
insurers' ratings are reduced by these rating agencies, it would likely reduce
the effective rating of many of the bonds insured by that insurer or insurers.
It is important to note that municipal bonds historically have had a very low
rate of default.

RECENT DEVELOPMENTS IN THE AUCTION RATE PREFERRED MARKETS

Beginning in February 2008, more shares for sale were submitted in the regularly
scheduled auctions for the preferred shares issued by these Funds than there
were offers to buy. This meant that these auctions "failed to clear'' and that
many or all auction preferred shareholders who wanted to sell their shares in
these auctions were unable to do so. This decline in liquidity in auction
preferred shares did not lower the credit quality of these shares, and auction
preferred shareholders unable to sell their shares received distributions at the
"maximum rate'' applicable to failed auctions as calculated in accordance with
the pre-established terms of the auction preferred shares. At the time this
report was prepared, the Funds' managers could not predict when future auctions
might succeed in attracting sufficient buyers for the shares offered, if ever.
The Funds' managers are working diligently to refund the auction preferred
shares, and have made progress in these efforts, but at present there is no
assurance that these efforts will succeed. These developments generally do not
affect


                                       8



the management or investment policies of these Funds. However, one implication
of these auction failures for common shareholders is that the Funds' cost of
leverage will likely be higher, at least temporarily, than it otherwise would
have been had the auctions continued to be successful. As a result, the Funds'
future common share earnings may be lower than they otherwise would have been.

Common Share
Dividend and Share Price
                 INFORMATION



As previously noted, all of the Funds in this report use leverage to potentially
enhance opportunities for additional income for common shareholders. This
strategy continued to provide support for the Funds' income streams during this
turbulent period. As a result, the dividends of all three of these Funds
remained stable throughout the six-month reporting period ended April 30, 2008.

Due to capital gains generated by normal portfolio activity, common shareholders
of the Funds received capital gains and/or net ordinary income distributions at
the end of December 2007 as follows:

                                     Short-Term Capital Gains
           Long-Term Capital Gains     and/or Ordinary Income
                       (per share)                (per share)

NPI                             --                    $0.0009
NPM                        $0.0215                    $0.0040
NPT                             --                    $0.0036

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 common share 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 common share NAV. Each Fund will, over time,
pay all of its net investment income as dividends to shareholders. As of April
30, 2008, all three of the Funds in this report had positive UNII balances,
based upon our best estimate, for tax purposes and positive UNII balances for
financial statement purposes.

As of April 30, 2008, the Funds' common share prices were trading at discounts
to their common share NAVs as shown in the accompanying chart:

NPT                            -9.98%                   -10.72%


COMMON SHARE REPURCHASE AND SHARE PRICE INFORMATION

On July 10, 2007, the Board of Directors of NPM approved an open market share
repurchase program, as part of a broad, ongoing effort designed to support the
market prices of the Fund's common shares. Repurchases not only help to support
the market price, but because such purchases are made at a discount to NAV, they
have the effect of augmenting NAV. Under the terms of the program, NPM may
repurchase up to 10% of its outstanding common shares. As of April 30, 2008, NPM
had repurchased 297,500 common shares, representing 0.7% of the Fund's total
common shares outstanding.

(1)  The percentages shown in the foregoing chart may reflect the ratings on
     certain bonds insured by AMBAC, CIFG, FGIC, MBIA and XLCA as of April 30,
     2008. Please see the Portfolio Manager's Commentary for an expanded
     discussion of the affect on the Fund of changes to the ratings of certain
     bonds in the portfolio resulting from changes to the ratings of the
     underlying insurers both during the period and after period end.

====================================================================================================================================
USD-LIBOR (United States Dollar-London Inter-Bank Offered Rate).

               (1)  All percentages shown in the Portfolio of Investments are
                    based on net assets applicable to Common shares unless
                    otherwise noted.

               (2)  Optional Call Provisions: Dates (month and year) and prices
                    of the earliest optional call or redemption. There may be
                    other call provisions at varying prices at later dates.
                    Certain mortgage-backed securities may be subject to
                    periodic principal paydowns.

               (3)  Ratings: Using the higher of Standard & Poor's Group
                    ("Standard & Poor's") or Moody's Investor Service, Inc.
                    ("Moody's") rating. Ratings below BBB by Standard & Poor's
                    or Baa by Moody's are considered to be below investment
                    grade.

                    The Portfolio of Investments may reflect the ratings on
                    certain bonds insured by AMBAC, CIFG, FGIC, MBIA and XLCA as
                    of April 30, 2008. Please see the Portfolio Manager's
                    Commentary for an expanded discussion of the affect on the
                    Fund of changes to the ratings of certain bonds in the
                    portfolio resulting from changes to the ratings of the
                    underlying insurers both during the period and after period
                    end.

               (4)  Backed by an escrow or trust containing sufficient U.S.
                    Government or U.S. Government agency securities which ensure
                    the timely payment of principal and interest. Such
                    investments are normally considered to be equivalent to AAA
                    rated securities.

               (5)  Portion of investment, with an aggregate market value of
                    $1,042,916, has been pledged to collateralize the net
                    payment obligations under forward swap contracts.

               (6)  Investment has a maturity of more than one year, but has
                    variable rate and demand features which qualify it as a
                    short-term investment. The rate disclosed is that in effect
                    at the end of the reporting period. This rate changes
                    periodically based on market conditions or a specified
                    market index.

               (7)  Preferred Shares, at Liquidation Value as a percentage of
                    total investments is (35.7)%.

               (8)  Effective date represents the date on which both the Fund
                    and counterparty commence interest payment accruals on each
                    forward swap contract.

               N/R  Not rated.

             (ETM)  Escrowed to maturity.

              (IF)  Inverse floating rate investment.

              (UB)  Underlying bond of an inverse floating rate trust reflected

               (1)  All percentages shown in the Portfolio of Investments are
                    based on net assets applicable to Common shares unless
                    otherwise noted.

               (2)  Optional Call Provisions: Dates (month and year) and prices
                    of the earliest optional call or redemption. There may be
                    other call provisions at varying prices at later dates.
                    Certain mortgage-backed securities may be subject to
                    periodic principal paydowns.

               (3)  Ratings: Using the higher of Standard & Poor's Group
                    ("Standard & Poor's") or Moody's Investor Service, Inc.
                    ("Moody's") rating. Ratings below BBB by Standard & Poor's
                    or Baa by Moody's are considered to be below investment
                    grade.

                    The Portfolio of Investments may reflect the ratings on
                    certain bonds insured by AMBAC, CIFG, FGIC, MBIA and XLCA as
                    of April 30, 2008. Please see the Portfolio Manager's
                    Commentary for an expanded discussion of the affect on the
                    Fund of changes to the ratings of certain bonds in the
                    portfolio resulting from changes to the ratings of the
                    underlying insurers both during the period and after period
                    end.

               (4)  Backed by an escrow or trust containing sufficient U.S.
                    Government or U.S. Government agency securities which ensure
                    the timely payment of principal and interest. Such
                    investments are normally considered to be equivalent to AAA
                    rated securities.

               (5)  Investment has a maturity of more than one year, but has
                    variable rate and demand features which qualify it as a
                    short-term investment. The rate disclosed is that in effect
                    at the end of the reporting period. This rate changes
                    periodically based on market conditions or a specified
                    market index.

               (6)  Preferred Shares, at Liquidation Value as a percentage of
                    total investments is (35.8)%.

               N/R  Not rated.

             (ETM)  Escrowed to maturity.

              (IF)  Inverse floating rate investment.

              (UB)  Underlying bond of an inverse floating rate trust reflected
                    as a financing transaction pursuant to the provisions of
                    SFAS No. 140.

                    otherwise noted.

               (2)  Optional Call Provisions: Dates (month and year) and prices
                    of the earliest optional call or redemption. There may be
                    other call provisions at varying prices at later dates.
                    Certain mortgage-backed securities may be subject to
                    periodic principal paydowns.

               (3)  Ratings: Using the higher of Standard & Poor's Group
                    ("Standard & Poor's") or Moody's Investor Service, Inc.
                    ("Moody's") rating. Ratings below BBB by Standard & Poor's
                    or Baa by Moody's are considered to be below investment
                    grade.

                    The Portfolio of Investments may reflect the ratings on
                    certain bonds insured by AMBAC, CIFG, FGIC, MBIA and XLCA as
                    of April 30, 2008. Please see the Portfolio Manager's
                    Commentary for an expanded discussion of the affect on the
                    Fund of changes to the ratings of certain bonds in the
                    portfolio resulting from changes to the ratings of the
                    underlying insurers both during the period and after period
                    end.

               (4)  Backed by an escrow or trust containing sufficient U.S.
                    Government or U.S. Government agency securities which ensure
                    the timely payment of principal and interest. Such
                    investments are normally considered to be equivalent to AAA
                    rated securities.

               (5)  Investment has a maturity of more than one year, but has

Notes to
FINANCIAL STATEMENTS (Unaudited)



1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

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) (collectively, the "Funds"). 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 or futures contract, each Fund may use market
quotes provided by major broker/dealers in such investments. If it is determined
that the market price for an investment or derivative instrument is unavailable
or inappropriate, the Board of Directors of the Funds, or its designee, may
establish fair value in accordance with procedures established in good faith by
the Board of Directors. 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, 2008, there were
no such outstanding purchase commitments in any of the Funds.

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.

Federal Income Taxes

Each Fund is a separate taxpayer for federal income tax purposes. Each Fund
intends to distribute substantially all of its 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.


                                       64



Effective April 30, 2008, the Funds adopted Financial Accounting Standards Board
(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 affirmative evaluation of tax positions taken or expected to be
taken in the course of preparing the Funds' tax returns to determine whether it
is "more-likely-than-not" (i.e., a greater than 50-percent likelihood) of being
sustained by the applicable tax authority. Tax positions not deemed to meet the
more-likely-than-not threshold may result in a tax benefit or expense in the
current year.

Implementation of FIN 48 required management of the Funds to analyze all open
tax years, as defined by the statute of limitations, for all major
jurisdictions, which includes federal and certain states. Open tax years are
those that are open for examination by taxing authorities (i.e., generally the
last four tax year ends and the interim tax period since then). The Funds have
no examinations in progress.

For all open tax years and all major taxing jurisdictions through the end of the
reporting period, management of the Funds has reviewed all tax positions taken
or expected to be taken in the preparation of the Funds' tax returns and
concluded the adoption of FIN 48 resulted in no impact to the Funds' net assets
or results of operations as of and during the six months ended April 30, 2008.

The Funds are also not aware of any tax positions for which it is reasonably
possible that the total amounts of unrecognized tax benefits will significantly
change in the next twelve months.

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 at least annually. Furthermore, capital
gains are distributed only to the extent they exceed available capital loss
carryforwards.

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:

Beginning in February 2008, more shares for sale were submitted in the regularly
scheduled auctions for the Preferred shares issued by the Funds than there were
offers to buy. This meant that these auctions "failed to clear,'' and that many
Preferred shareholders who wanted to sell their shares in these auctions were
unable to do so. Preferred shareholders unable to sell their shares received
distributions at the "maximum rate'' applicable to failed auctions as calculated
in accordance with the pre-established terms of the Preferred shares.

These developments generally do not affect the management or investment policies
of the Funds. However, one implication of these auction failures for Common
shareholders is that the Funds' cost of leverage will likely be higher, at least
temporarily, than it otherwise would have been had the auctions continued to be
successful. As a result, the Funds' future Common share earnings may be lower
than they otherwise would have been.

Inverse Floating Rate Securities

Each Fund is authorized to 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"). A Fund may also enter into shortfall and
forbearance agreements (sometimes referred to as a "recourse trust" or "credit
recovery swap") with a broker-dealer by which a Fund agrees to reimburse the
broker-dealer, in certain circumstances, for the difference between the
liquidation value of the fixed-rate bond held by the trust and the liquidation
value of the floating rate certificates, as well as any shortfalls in interest
cash flows. The inverse floater held by a Fund gives the Fund the right (a) to
cause the holders of the floating rate certificates to tender their notes at
par, and (b) to have the broker transfer the fixed-rate bond held by the trust
to the Fund, thereby collapsing the trust. 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, recourse trust or credit recovery swap 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 "Interest
expense on floating rate obligations" in the Statement of Operations.

During the six months ended April 30, 2008, each Fund invested in externally
deposited inverse floaters and/or self-deposited inverse floaters.

The average floating rate obligations outstanding and average annual interest
rate and fees related to self-deposited inverse floaters during the six months
ended April 30, 2008, were as follows:

Forward Swap Transactions

Each Fund is authorized to invest in forward interest rate swap transactions.
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. Each Fund invested in
forward interest rate swap transactions during the six months ended April 30,
2008.

Futures Contracts

Each Fund is 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 recognized 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. None of the Funds invested in futures contracts during the six
months ended April 30, 2008.

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.

Zero Coupon Securities

Each Fund is authorized to invest in zero coupon securities. A zero coupon
security does not pay a regular interest coupon to its holders during the life
of the security. Tax-exempt income to the holder of the security comes from
accretion of the difference between the original purchase price of the security
at issuance and the par value of the security at maturity and is effectively
paid at maturity. Such securities are included in the Portfolios of Investments
with a 0.000% coupon rate in their description. The market prices of zero coupon
securities generally are more volatile than the market prices of securities that
pay interest periodically.

Custodian Fee Credit

Each Fund has an arrangement with the custodian bank whereby certain custodian
fees and expenses are reduced by net credits earned on each Fund's cash on
deposit with the bank. Such deposit arrangements are an alternative to overnight
investments. Credits for cash balances may be offset by charges for any days on
which a Fund overdraws its account at the custodian bank.

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

On July 10, 2007, the Board of Directors of Premium Income 2 (NPM) approved an
open-market share repurchase program, as part of a broad, ongoing effort
designed to support the market prices of the Fund's Common shares. Under the
terms of the program, the Fund may repurchase up to 10% of its outstanding
Common shares.

Transactions in Common shares were as follows:

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 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.

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, 2008, the complex-level fee rate was .1855%.

The complex-level fee schedule is as follows:

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

(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.


                                       70



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 Statement on Financial Accounting Standards
No. 157

In September 2006, the FASB issued 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, 2008,
management does 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.

Financial Accounting Standards Board Statement of Financial Accounting Standards
No. 161

In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative
Instruments and Hedging Activities." This standard is intended to enhance
financial statement disclosures for derivative instruments and hedging
activities and enable investors to understand: a) how and why a fund uses
derivative instruments, b) how derivative instruments and related hedge items
are accounted for, and c) how derivative instruments and related hedge items
affect a fund's financial position, results of operations and cash flows. SFAS
No. 161 is effective for financial statements issued for fiscal years and
interim periods beginning after November 15, 2008. As of April 30, 2008,
management does not believe the adoption of SFAS No. 161 will impact the
financial statement amounts; however, additional footnote disclosures may be
required about the use of derivative instruments and hedging items.

Auction Rate Preferred Shares (ARPS)

On June 11, 2008, Nuveen announced the Fund Board's approval of plans to use
tender option bonds (TOBs), also known as inverse floating rate securities or
inverse floaters, to refinance a portion of the funds' outstanding ARPS, whose
auctions have been failing for several months, including an initial phase of
approximately $1 billion in forty-one funds. Of this amount, Nuveen expects that
approximately $560 million in ARPS redemption notices will be issued shortly for
thirteen funds, including Premium Income Municipal Fund (NPI), Premium Income
Municipal Fund 2 (NPM) and Premium Income Municipal Fund 4 (NPT).

*    Total Return on Market Value is the combination of changes in the market
     price per share and the effect of reinvested dividend income and reinvested
     capital gains distributions, if any, at the average price paid per share at
     the time of reinvestment. The last dividend declared in the period, which
     is typically paid on the first business day of the following month, is
     assumed to be reinvested at the ending market price. The actual
     reinvestment for the last dividend declared in the period may take place
     over several days, and in some instances may not be based on the market
     price, so the actual reinvestment price may be different from the price
     used in the calculation. Total returns are not annualized.

     Total Return on Common Share Net Asset Value is the combination of changes
     in Common share net asset value, reinvested dividend income at net asset
     value and reinvested capital gains distributions at net asset value, if
     any. The last dividend declared in the period, which is typically paid on
     the first business day of the following month, is assumed to be reinvested
     at the ending net asset value. The actual reinvest price for the last
     dividend declared in the period may often be based on the Fund's market
     price (and not its net asset value), and therefore may be different from
     the price used in the calculation. Total returns are not annualized.

**   After custodian fee credit and legal fee refund, where applicable.

***  Annualized.

+    The amounts shown are based on Common share equivalents.

++   Ratios do not reflect the effect of dividend payments to Preferred
     shareholders; income ratios reflect income earned on assets attributable to
     Preferred shares.

(a)  Interest expense arises from the application of SFAS No. 140 to certain
     inverse floating rate transactions entered into by the Fund as more fully
     described in Footnote 1- Inverse Floating Rate Securities.

(b)  For the six months ended April 30, 2008.

================================================================================
*    Total Return on Market Value is the combination of changes in the market
     price per share and the effect of reinvested dividend income and reinvested
     capital gains distributions, if any, at the average price paid per share at
     the time of reinvestment. The last dividend declared in the period, which
     is typically paid on the first business day of the following month, is
     assumed to be reinvested at the ending market price. The actual
     reinvestment for the last dividend declared in the period may take place
     over several days, and in some instances may not be based on the market
     price, so the actual reinvestment price may be different from the price
     used in the calculation. Total returns are not annualized.

     Total Return on Common Share Net Asset Value is the combination of changes
     in Common share net asset value, reinvested dividend income at net asset
     value and reinvested capital gains distributions at net asset value, if
     any. The last dividend declared in the period, which is typically paid on
     the first business day of the following month, is assumed to be reinvested
     at the ending net asset value. The actual reinvest price for the last
     dividend declared in the period may often be based on the Fund's market
     price (and not its net asset value), and therefore may be different from
     the price used in the calculation. Total returns are not annualized.

**   After custodian fee credit and legal fee refund, where applicable.

***  Annualized.

+    The amounts shown are based on Common share equivalents.

++   Ratios do not reflect the effect of dividend payments to Preferred
     shareholders; income ratios reflect income earned on assets attributable to
     Preferred shares.

(a)  Interest expense arises from the application of SFAS No. 140 to certain
     inverse floating rate transactions entered into by the Fund as more fully
     described in Footnote 1- Inverse Floating Rate Securities.

Reinvest Automatically
EASILY and CONVENIENTLY

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.


                                       76



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


[]   Auction Rate Bond: An auction rate bond is a security whose interest
     payments are adjusted periodically through an auction process, which
     process typically also serves as a means for buying and selling the bond.
     Auctions that fail to attract enough buyers for all the shares offered for
     sale are deemed to have "failed", with current holders receiving a
     formula-based interest rate until the next scheduled auction.

[]   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 Preferred 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.

[]   Zero Coupon Bond: A zero coupon bond does not pay a regular interest coupon
     to its holders during the life of the bond. Tax-exempt income to the holder
     of the bond comes from accretion of the difference between the original
     purchase price of the bond at issuance and the par value of the bond at
     maturity and is effectively paid at maturity. The market prices of zero
     coupon bonds generally are more volatile than the market prices of bonds
     that pay interest periodically.
