Nuveen Investments Closed-End Fund
NIM

     Portfolio Manager's
          COMMENTS

Portfolio manager Paul Brennan discusses U.S. economic and municipal market
conditions, key investment strategies, and the annual performance of the Nuveen
Select Maturities Municipal Fund. With over 17 years of investment experience,
including 15 years with Nuveen, Paul has managed NIM since July 2006.

WHAT FACTORS AFFECTED THE U.S. ECONOMY AND MUNICIPAL MARKET DURING THE 12-MONTH
REPORTING PERIOD ENDED MARCH 31, 2007?

Between April 1, 2006, and March 31, 2007, we saw interest rates at the short
end of the yield curve rise modestly, while longer-term rates generally
declined. In May and June 2006, the Federal Reserve announced two additional
increases of 0.25% each in the Fed funds rate, bringing this short-term target
to 5.25%. Then, in the first pause in rate increases in more than two years, the
Fed left monetary policy unchanged during the remaining nine months of this
reporting period while it kept close tabs on inflationary pressures and the pace
of economic growth. Over the same 12-month period, the yield on the benchmark
10-year U.S. Treasury note fell 20 basis points to end March 2007 at 4.65%. In
the municipal market, the yield on the Bond Buyer 25 Revenue Bond Index, a
widely followed measure of longer-term municipal market rates, fell to 4.48% at
the end of March 2007, a decline of 66 basis points from the end of March 2006.
As shorter-term municipal bond interest rates approached the levels of long-term
rates, the municipal bond yield curve continued to flatten, with longer
duration1 bonds generally outperforming those with shorter durations during this
period.

Although many market observers had expected to see the Fed funds rate begin to
ease in early 2007, slowing economic growth, higher energy prices and a slumping
housing market kept the Fed on the sidelines. After posting an annualized gain
of 5.6% in the first quarter of 2006, the U.S. gross domestic product, a closely
watched measure, expanded 2.6% in the second quarter, 2.0% in the third quarter,
and 2.5% in the fourth quarter (all GDP numbers annualized). In the first
quarter of 2007, the rate of GDP growth slowed even further to an annualized
1.3%, the weakest rate in four years.



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.


                                       4



Over the 12 months ended March 2007, municipal bond issuance nationwide totaled
$417.8 billion, up 11% from the previous 12 months. This total reflected record
supply during the first three months of 2007, when $104 billion in new
securities came to market, an increase of 49% from the same period in 2006. A
major factor in the first quarter 2007 volume was an 88% increase in advance
refundings2 driven by attractive borrowing rates for issuers. Strong demand for
municipal bonds was more than adequate to absorb the surge in issuance, as
retail investors, institutional investors such as hedge funds and arbitragers,
and overseas investors all participated in the market.


WHAT KEY STRATEGIES WERE USED TO MANAGE NIM DURING THIS REPORTING PERIOD?

In the interest rate environment of the past 12 months, where the flattening
yield curve remained a dominant market factor, we believed that the Fund's
emphasis on an intermediate-term investment strategy helped its overall
performance. To maintain the Fund's intermediate-term characteristics, our
purchases for NIM's portfolio focused mainly on attractively priced bonds
maturing in 15 years or less. This approach was consistent with our overall view
that the flatter yield curve made it less compelling to take on the additional
risk typically associated with longer maturities or durations.

During this period, a number of large municipal offerings were brought to
market, which provided us with more bonds from which to choose. While the
majority of our purchases over the 12 month period were higher-rated securities
(AAA and AA), we also pursued opportunities that offered unusual structural
features that we believed could add value to the Fund. As a result, some of the
additions to NIM's portfolio included securities with adjustable rate coupons
and unusual call structures or sinking fund provisions.

Our purchases of AAA rated bonds, combined with several Fund holdings that were
upgraded to AAA through advance refundings resulted in an increase of
approximately 5% in NIM's allocation of AAA rated bonds over this period. The
Fund's allocations to lower-rated categories, particularly bonds rated BBB,
declined slightly. Nevertheless as of March 31, 2007, NIM continued to have
healthy exposure (30% of the portfolio) to bonds rated A or lower and non-rated
bonds.


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.

For the 12 months ended March 31, 2007, the total return on net asset value
(NAV) for NIM slightly exceeded the return for the Lehman Brothers 7-Year
Municipal Bond Index. During this reporting period, NIM's return was influenced
by duration and yield curve positioning, allocations to lower-rated credits,
advance refundings, and bond call exposure.

As the yield curve flattened over the course of this period, duration and yield
curve positioning played a key role in NIM's performance. While NIM continued to
offer an intermediate-term orientation4 on average, the Fund maintained a slight
"barbell" bias in its maturity structure, i.e., greater focus on securities at
both the longer and shorter ends of the maturity range. This overall positioning
was very positive for the Fund's performance in the interest rate environment of
the past 12 months.

With bonds rated BBB or lower and nonrated bonds generally outperforming other
credit quality sectors during this period, NIM benefited from its allocation of
lower-quality credits. The performance of this sector was largely the result of
investor demand for the higher yields typically associated with lower-quality
bonds, which drove up their value. Among the lower-rated holdings making
contributions to NIM's return for this period were health care (including
hospital), charter school, and industrial development revenue bonds as well as
tobacco credits. At period end, NIM held approximately 4% of its portfolio in
lower-rated bonds backed by the 1998 master tobacco settlement agreement.



3    The Lehman Brothers 7-Year Municipal Bond Index is an unleveraged,
     unmanaged national index comprising a broad range of investment-grade
     municipal bonds with maturities ranging from six to eight years. Results
     for the Lehman Brothers index do not reflect any expenses.

4    In keeping with its investment parameters, NIM maintains an average
     effective maturity of 12 years or less for portfolio holdings.


                                       6



We also continued to see positive impact from advance refunding activity during
this 12-month period, which benefited NIM through price appreciation and
enhanced credit quality.

NIM's performance was also impacted by significant bond calls and the impact of
previous refundings activity. On the whole, bonds with short call dates did not
perform as strongly as bonds with longer call dates and better call protection
as interest rates declined during this period. As a result, NIM's holdings of
older, previously pre-refunded bonds tended to underperform the general
municipal market during this period, due primarily to their shorter effective
maturities. However, we continued to hold these short call bonds as long as
possible because their higher yields benefited NIM's income stream. While an
elevated level of call activity is not unusual for a fund with an intermediate
maturity focus like NIM, we have worked to offset some of the impact of this
activity by placing more emphasis on securities with longer maturities (i.e.,
the barbell maturity structure mentioned earlier).


                                       7



Dividend and Share Price
       INFORMATION


During this period, proceeds from older, higher-yielding bonds that matured or
were called were reinvested into bonds currently available in the market, which
generally offered lower yields. This impacted NIM's income stream, resulting in
two monthly dividend reductions during the 12-month period ended March 31, 2007.
Prior to these cuts, which took effect in September 2006 and March 2007, NIM had
provided shareholders with 33 consecutive months of stable dividends.

Due to normal portfolio activity, common shareholders of NIM received a net
ordinary income distribution of $0.0052 at the end of December 2006.

NIM seeks to pay stable dividends at rates that reflect the Fund's past results
and projected future performance. During certain periods, NIM 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. NIM will, over time, pay all of its net investment income as dividends to
shareholders. As of March 31, 2007, NIM had a positive UNII balance for tax
purposes and a negative UNII balance for financial statement purposes.

As of March 31, 2007, NIM was trading at a discount of -2.45% to its NAV. The
Fund's average discount over the entire 12-month reporting period was -3.86%.

Report of
   INDEPENDENT REGISTERED PUBLIC
   ACCOUNTING FIRM



TO THE BOARD OF TRUSTEES AND SHAREHOLDERS
NUVEEN SELECT MATURITIES MUNICIPAL FUND


We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of Nuveen Select Maturities Municipal Fund as of
March 31, 2007, and the related statement of operations for the year then ended,
the statement of changes in net assets for each of the two years in the period
then ended, and the financial highlights for each of the periods indicated
therein. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of March 31, 2007, by correspondence with the custodian and
brokers. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Nuveen
Select Maturities Municipal Fund at March 31, 2007, the results of its
operations for the year then ended, changes in its net assets for each of the
two years in the period then ended, and its financial highlights for each of the
periods indicated therein in conformity with U.S. generally accepted accounting
principles.

Notes to
       FINANCIAL STATEMENTS



1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES

The fund covered in this report and its corresponding New York Stock Exchange
symbol is Nuveen Select Maturities Municipal Fund (NIM) (the "Fund"). The Fund
is registered under the Investment Company Act of 1940, as amended, as a
closed-end, diversified management investment company.

The Fund seeks to provide current income exempt from regular federal income tax,
consistent with the preservation of capital by investing in a diversified,
investment-grade quality portfolio of municipal obligations with intermediate
characteristics. In managing its portfolio, the Fund has purchased municipal
obligations having remaining effective maturities of no more than fifteen years
with respect to 80% of its total assets that, in the opinion of the Adviser,
represent the best value in terms of the balance between yield and capital
preservation currently available from the intermediate sector of the municipal
market. The Adviser will actively monitor the effective maturities of the Fund's
investments in response to prevailing market conditions, and will adjust its
portfolio consistent with its investment policy of maintaining an average
effective remaining maturity of twelve years or less.

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

Investment Valuation

The prices of municipal bonds in the Fund's investment portfolio are provided by
a pricing service approved by the Fund's Board of Trustees. 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. If the
pricing service is unable to supply a price for a municipal bond, the 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 Trustees
of the Fund, 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 Fund has 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 March 31, 2007, the Fund
had no such outstanding purchase commitments.

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

The 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,
the 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 Fund. Net realized
capital gains and ordinary income distributions paid by the Fund are subject to
federal taxation.


                                       20



Dividends and Distributions to 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.

Distributions to 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.

Derivative Financial Instruments

The Fund is authorized to invest in certain derivative financial instruments
including futures, forward, swap and option contracts, and other financial
instruments with similar characteristics. Although the Fund is authorized to
invest in such financial instruments, and may do so in the future, it did not
invest in any such instruments during the fiscal year ended March 31, 2007.

Custodian Fee Credit

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

Indemnifications

Under the Fund's organizational documents, its Officers and Trustees are
indemnified against certain liabilities arising out of the performance of their
duties to the Fund. In addition, in the normal course of business, the Fund
enters into contracts that provide general indemnifications to other parties.
The Fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the Fund that have not yet
occurred. However, the Fund has not had prior claims or losses pursuant to these
contracts and expects 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 from operations during the reporting period. Actual
results may differ from those estimates.

2. FUND SHARES

The Fund did not engage in transactions in its own shares during the fiscal year
ended March 31, 2007. During the fiscal year ended March 31, 2006, 1,429 shares
were issued to shareholders due to reinvestment of distributions.

3. INVESTMENT TRANSACTIONS

Purchases and sales (including maturities but excluding short-term investments)
during the fiscal year ended March 31, 2007, aggregated $17,835,072 and
$20,329,949, respectively.

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 and timing differences in recognizing
certain gains and losses on investment transactions. 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 Fund.

At March 31, 2007, the cost of investments was $119,643,609.

Gross unrealized appreciation and gross unrealized depreciation of investments
at March 31, 2007, were as follows:

--------------------------------------------------------------------------------
Gross unrealized:
   Appreciation                                                      $3,725,261
   Depreciation                                                        (315,927)
--------------------------------------------------------------------------------
Net unrealized appreciation (depreciation) of investments            $3,409,334

Notes to
    FINANCIAL STATEMENTS (CONTINUED)



The tax components of undistributed net tax-exempt income, net ordinary income
and net long-term capital gains at March 31, 2007, the Fund's tax year end, were
as follows:

--------------------------------------------------------------------------------
Undistributed net tax-exempt income *                                  $223,968
Undistributed net ordinary income **                                        713
Undistributed net long-term capital gains                                    --
================================================================================
*    Undistributed net tax-exempt income (on a tax basis) has not been reduced
     for the dividend declared on March 1, 2007, paid on April 2, 2007.
**   Net ordinary income consists of taxable market discount income and net
     short-term capital gains, if any.

The tax character of distributions paid during the tax years ended March 31,
2007 and March 31, 2006, was designated for purposes of the dividends paid
deduction as follows:

2007
--------------------------------------------------------------------------------
Distributions from net tax-exempt income ***                         $5,764,329
Distributions from net ordinary income **                                64,461
Distributions from net long-term capital gains                               --
================================================================================

2006
--------------------------------------------------------------------------------

Distributions from net tax-exempt income                             $5,875,503
Distributions from net ordinary income **                                17,355
Distributions from net long-term capital gains                               --
================================================================================

**   Net ordinary income consists of taxable market discount income and net
     short-term capital gains, if any.

***  The Fund hereby designates this amount paid during the fiscal year ended
     March 31, 2007, as an Exempt Interest Dividend.

At March 31, 2007, the Fund had unused capital loss carryforwards of $15,306,616
available for federal income tax purposes to be applied against future capital
gains, if any. If not applied, $14,922 of the carryforward will expire in the
year 2010, $6,523,386 will expire in 2011, $8,737,799 will expire in 2012,
$4,977 will expire in 2013, $14,448 will expire in 2014 and $11,084 will expire
in 2015.

The Fund elected to defer net realized losses from investments incurred from
November 1, 2006 through March 31, 2007 ("post-October losses") in accordance
with federal income tax regulations. Post-October losses of $11,832 were treated
as having arisen on the first day of the following fiscal year.

5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES

The 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 the 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, is based upon the average daily net
assets of the Fund as follows:

AVERAGE DAILY NET ASSETS                                     FUND-LEVEL FEE RATE
--------------------------------------------------------------------------------
For the first $125 million                                                .3000%
For the next $125 million                                                 .2875
For the next $250 million                                                 .2750
For the next $500 million                                                 .2625
For the next $1 billion                                                   .2500
For net assets over $2 billion                                            .2375
================================================================================


                                       22



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 March 31, 2007, the complex-level fee rate was .1834%.

COMPLEX-LEVEL ASSETS(1)                                   COMPLEX-LEVEL FEE RATE
--------------------------------------------------------------------------------
For the first $55 billion                                                 .2000%
For the next $1 billion                                                   .1800
For the next $1 billion                                                   .1600
For the next $3 billion                                                   .1425
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 Fund pays no
compensation directly to those of its Trustees who are affiliated with the
Adviser or to its Officers, all of whom receive remuneration for their services
to the Fund from the Adviser or its affiliates. The Board of Trustees has
adopted a deferred compensation plan for independent Trustees that enables
Trustees 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 Fund's 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 calculations in the first required financial statement reporting
period. As a result, the Fund must begin to incorporate FIN 48 into its NAV
calculations by September 28, 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
Fund.

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 March 31, 2007, the Fund 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.

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.


                                       32



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.

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.

ITEM 2. CODE OF ETHICS.

As of the end of the period covered by this report, the registrant has adopted a
code of ethics that applies to the registrant's principal executive officer,
principal financial officer, principal accounting officer or controller, or
persons performing similar functions. There were no amendments to or waivers
from the Code during the period covered by this report. The registrant has
posted the code of ethics on its website at www.nuveen.com/etf. (To view the
code, click on the Investor Resources drop down menu box, click on Fund
Governance and then click on Code of Conduct.)

ITEM 3. AUDIT COMMITTEE FINANCIAL EXPERT.

The registrant's Board of Directors or Trustees determined that the registrant
has at least one "audit committee financial expert" (as defined in Item 3 of
Form N-CSR) serving on its Audit Committee. The registrant's audit committee
financial expert is Jack B. Evans, Chairman of the Audit Committee, who is
"independent" for purposes of Item 3 of Form N-CSR.

Mr. Evans was formerly President and Chief Operating Officer of SCI Financial
Group, Inc., a full service registered broker-dealer and registered investment
adviser ("SCI"). As part of his role as President and Chief Operating Officer,
Mr. Evans actively supervised the Chief Financial Officer (the "CFO") and
actively supervised the CFO's preparation of financial statements and other
filings with various regulatory authorities. In such capacity, Mr. Evans was
actively involved in the preparation of SCI's financial statements and the
resolution of issues raised in connection therewith. Mr. Evans has also served
on the audit committee of various reporting companies. At such companies, Mr.
Evans was involved in the oversight of audits, audit plans, and the preparation
of financial statements. Mr. Evans also formerly chaired the audit committee of
the Federal Reserve Bank of Chicago.

ITEM 4. PRINCIPAL ACCOUNTANT FEES AND SERVICES.

                     Nuveen Select Maturities Municipal Fund

The following tables show the amount of fees that Ernst & Young LLP, the Fund's
auditor, billed to the Fund during the Fund's last two full fiscal years. For
engagements with Ernst & Young LLP the Audit Committee approved in advance all
audit services and non-audit services that Ernst & Young LLP provided to the
Fund, except for those non-audit services that were subject to the pre-approval
exception under Rule 2-01 of Regulation S-X (the "pre-approval exception"). The
pre-approval exception for services provided directly to the Fund waives the
pre-approval requirement for services other than audit, review or attest
services if: (A) the aggregate amount of all such services provided constitutes
no more than 5% of the total amount of revenues paid by the Fund to its
accountant during the fiscal year in which the services are provided; (B) the
Fund did not recognize the services as non-audit services at the time of the
engagement; and (C) the services are promptly brought to the Audit Committee's
attention, and the Committee (or its delegate) approves the services before the
audit is completed.

The Audit Committee has delegated certain pre-approval responsibilities to its
Chairman (or, in his absence, any other member of the Audit Committee).

(1)  "Audit Fees" are the aggregate fees billed for professional services for
     the audit of the Fund's annual financial statements and services provided
     in connection with statutory and regulatory filings or engagements.

(2)  "Audit Related Fees" are the aggregate fees billed for assurance and
     related services reasonably related to the performance of the audit or
     review of financial statements and are not reported under "Audit Fees".

(3)  "Tax Fees" are the aggregate fees billed for professional services for tax
     advice, tax compliance, and tax planning.

(4)  "All Other Fees" are the aggregate fees billed for products and services
     other than "Audit Fees", "Audit Related Fees", and "Tax Fees".

                 SERVICES THAT THE FUND'S AUDITOR BILLED TO THE
                  ADVISER AND AFFILIATED FUND SERVICE PROVIDERS

The following tables show the amount of fees billed by Ernst & Young LLP to
Nuveen Asset Management ("NAM" or the "Adviser"), and any entity controlling,
controlled by or under common control with NAM ("Control Affiliate") that
provides ongoing services to the Fund ("Affiliated Fund Service Provider"), for
engagements directly related to the Fund's operations and financial reporting,
during the Fund's last two full fiscal years.

The tables also show the percentage of fees subject to the pre-approval
exception. The pre-approval exception for services provided to the Adviser and
any Affiliated Fund Service Provider (other than audit, review or attest
services) waives the pre-approval requirement if: (A) the aggregate amount of
all such services provided constitutes no more than 5% of the total amount of
revenues paid to Ernst & Young LLP by the Fund, the Adviser and Affiliated Fund
Service Providers during the fiscal year in which the services are provided that
would have to be pre-approved by the Audit Committee; (B) the Fund did not
recognize the services as non-audit services at the time of the engagement; and
(C) the services are promptly brought to the Audit Committee's attention, and
the Committee (or its delegate) approves the services before the Fund's audit is
completed.

(1)  The amounts reported for the Fund under the column heading "Tax Fees"
     represents amounts billed to the Adviser exclusively for the preparation
     for the Fund's tax return, the cost of which is borne by the Adviser. In
     the aggregate, for all Nuveen funds for which Ernst & Young LLP serves as
     independent registered public accounting firm, these fees amounted to
     $161,400 in 2006. Beginning with fund fiscal years ending August 31, 2006,
     Ernst & Young LLP will no longer prepare the fund tax returns.

                               NON-AUDIT SERVICES

The following table shows the amount of fees that Ernst & Young LLP billed
during the Fund's last two full fiscal years for non-audit services. The Audit
Committee is required to pre-approve non-audit services that Ernst & Young LLP
provides to the Adviser and any Affiliated Fund Services Provider, if the
engagement related directly to the Fund's operations and financial reporting
(except for those subject to the de minimis exception described above). The
Audit Committee requested and received information from Ernst & Young LLP about
any non-audit services that Ernst & Young LLP rendered during the Fund's last
fiscal year to the Adviser and any Affiliated Fund Service Provider. The
Committee considered this information in evaluating Ernst & Young LLP's
independence.

"Non-Audit Fees billed to Adviser" for both fiscal year ends represent "Tax
Fees" billed to Adviser in their respective amounts from the previous table.

Audit Committee Pre-Approval Policies and Procedures. Generally, the Audit
Committee must approve (i) all non-audit services to be performed for the Fund
by the Fund's independent accountants and (ii) all audit and non-audit services
to be performed by the Fund's independent accountants for the Affiliated Fund
Service Providers with respect to operations and financial reporting of the
Fund. Regarding tax and research projects conducted by the independent
accountants for the Fund and Affiliated Fund Service Providers (with respect to
operations and financial reports of the Fund) such engagements will be (i)
pre-approved by the Audit Committee if they are expected to be for amounts
greater than $10,000; (ii) reported to the Audit Committee chairman for his
verbal approval prior to engagement if they are expected to be for amounts under
$10,000 but greater than $5,000; and (iii) reported to the Audit Committee at
the next Audit Committee meeting if they are expected to be for an amount under
$5,000.

ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

The registrant's Board of Directors or Trustees has a separately designated
Audit Committee established in accordance with Section 3(a)(58)(A) of the
Securities Exchange Act of 1934, as amended (15 U.S.C. 78c(a)(58)(A)). The
members of the audit committee are Robert P. Bremner, Lawrence H. Brown, Jack B.
Evans, William J. Schneider, Eugene S. Sunshine and effective January 1, 2007,
David J. Kundert.

ITEM 6. SCHEDULE OF INVESTMENTS.

See Portfolio of Investments in Item 1.

ITEM 7.  DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

The registrant invests its assets primarily in municipal bonds and cash
management securities. On rare occasions the registrant may acquire, directly or
through a special purpose vehicle, equity securities of a municipal bond issuer
whose bonds the registrant already owns when such bonds have deteriorated or are
expected shortly to deteriorate significantly in credit quality. The purpose of
acquiring equity securities generally will be to acquire control of the
municipal bond issuer and to seek to prevent the credit deterioration or
facilitate the liquidation or other workout of the distressed issuer's credit
problem. In the course of exercising control of a distressed municipal issuer,
NAM may pursue the registrant's interests in a variety of ways, which may entail
negotiating and executing consents, agreements and other arrangements, and
otherwise influencing the management of the issuer. NAM does not consider such
activities proxy voting for purposes of Rule 206(4)-6 under the 1940 Act, but
nevertheless provides reports to the registrant's Board of Trustees on its
control activities on a quarterly basis.

In the rare event that a municipal issuer were to issue a proxy or that the
registrant were to receive a proxy issued by a cash management security, NAM
would either engage an independent third party to determine how the proxy should
be voted or vote the proxy with the consent, or based on the instructions, of
the registrant's Board of Trustees or its representative. A member of NAM's
legal department would oversee the administration of the voting, and ensure that
records were maintained in accordance with Rule 206(4)-6, reports were filed
with the SEC on Form N-PX, and the results provided to the registrant's Board of
Trustees and made available to shareholders as required by applicable rules.

ITEM 8. PORTFOLIO MANAGERS OF CLOSED-END MANAGEMENT INVESTMENT COMPANIES.

PORTFOLIO MANAGER

The following individual has primary responsibility for the day-to-day
implementation of the registrant's investment strategies:

NAME                                     FUND
Paul Brennan                             Nuveen Select Maturities Municipal Fund

Other Accounts Managed. In addition to managing the registrant, the portfolio
manager is also primarily responsible for the day-to-day portfolio management of
the following accounts:

                          TYPE OF ACCOUNT            NUMBER OF
PORTFOLIO MANAGER             MANAGED                 ACCOUNTS      ASSETS
--------------------------------------------------------------------------------
Paul Brennan       Registered Investment Company        14       $12,334 million
                   Other Pooled Investment Vehicles      0       $ 0 million
                   Other Accounts                        1       $0.7 million

*    Assets are as of March 31, 2007. None of the assets in these accounts are
     subject to an advisory fee based on performance.

Compensation. Each portfolio manager's compensation consists of three basic
elements--base salary, cash bonus and long-term incentive compensation. The
compensation strategy is to annually compare overall compensation, including
these three elements, to the market in order to create a compensation structure
that is competitive and consistent with similar financial services companies. As
discussed below, several factors are considered in determining each portfolio
manager's total compensation. In any year these factors may include, among
others, the effectiveness of the investment strategies recommended by the
portfolio manager's investment team, the investment performance of the accounts
managed by the portfolio manager, and the overall performance of Nuveen
Investments, Inc. (the parent company of the NAM). Although investment
performance is a factor in determining the portfolio manager's compensation, it
is not necessarily a decisive factor. The portfolio manager's performance is
evaluated in part by comparing manager's performance against a specified
investment benchmark. This fund-specific benchmark is a customized subset
(limited to bonds in each Fund's specific state and with certain maturity
parameters) of the S&P/Investortools Municipal Bond index, an index comprised of
bonds held by managed municipal bond fund customers of Standard & Poor's
Securities Pricing, Inc. that are priced daily and whose fund holdings aggregate
at least $2 million. As of April 30, 2007, the S&P/Investortools Municipal Bond
index was comprised of 50,300 securities with an aggregate current market value
of $ 985,620.

Base salary. Each portfolio manager is paid a base salary that is set at a level
determined by NAM in accordance with its overall compensation strategy discussed
above. NAM is not under any current contractual obligation to increase a
portfolio manager's base salary.

Cash bonus. Each portfolio manager is also eligible to receive an annual cash
bonus. The level of this bonus is based upon evaluations and determinations made
by each portfolio manager's supervisors, along with reviews submitted by his
peers. These reviews and evaluations often take into account a number of
factors, including the effectiveness of the investment strategies recommended to
the NAM's investment team, the performance of the accounts for which he serves
as portfolio manager relative to any benchmarks established for those accounts,
his effectiveness in communicating investment performance to stockholders and
their representatives, and his contribution to the NAM's investment process and
to the execution of investment strategies. The cash bonus component is also
impacted by the overall performance of Nuveen Investments, Inc. in achieving its
business objectives.

Long-term incentive compensation. Each portfolio manager is eligible to receive
bonus compensation in the form of equity-based awards issued in securities
issued by Nuveen Investments, Inc. The amount of such compensation is dependent
upon the same factors articulated for cash bonus awards but also factors in his
long-term potential with the firm.

Material Conflicts of Interest. Each portfolio manager's simultaneous management
of the Registrant and the other accounts noted above may present actual or
apparent conflicts of interest with respect to the allocation and aggregation of
securities orders placed on behalf of the registrant and the other account. NAM,
however, believes that such potential conflicts are mitigated by the fact that
the NAM has adopted several policies that address potential conflicts of
interest, including best execution and trade allocation policies that are
designed to ensure (1) that portfolio management is seeking the best price for
portfolio securities under the circumstances, (2) fair and equitable allocation
of investment opportunities among accounts over time and (3) compliance with
applicable regulatory requirements. All accounts are to be treated in a
non-preferential manner, such that allocations are not based upon account
performance, fee structure or preference of the portfolio manager. In addition,
NAM has adopted a Code of Conduct that sets forth policies regarding conflicts
of interest.

Beneficial Ownership of Securities. As of the March 31, 2007, the portfolio
manager beneficially owned the following dollar range of equity securities
issued by the Registrant and other Nuveen Funds managed by NAM's municipal
investment team.
