Nuveen Select Maturities Municipal Fund
NIM

Portfolio Manager's
        COMMENTS

Portfolio manager John Miller discusses the economic and municipal market
environments, key investment strategies, and the annual performance of the
Nuveen Select Maturities Municipal Fund. With 13 years of municipal market
experience, including 10 years with Nuveen, John has managed NIM since 2001.



WHAT FACTORS AFFECTED THE U.S. ECONOMY AND MUNICIPAL MARKET DURING THE ANNUAL
REPORTING PERIOD ENDED MARCH 31, 2006?

During this reporting period, we saw an increase in interest rates across the
yield curve, although short-term rates rose at a much faster pace than
longer-term rates. Between April 1, 2005, and March 31, 2006, the Federal
Reserve announced eight increases of 0.25% each in the fed funds rate, raising
this short-term target by 200 basis points (from 2.75% to 4.75%). In all, the
Fed has implemented fifteen 0.25% increases in the fed funds rate since June
2004. However, yields in the longer part of the curve proved to be more
resistant to increases. The yield on the benchmark 10-year U.S. Treasury note
ended March 2006 at 4.85%, up from 4.50% twelve months earlier, while the yield
on the Bond Buyer 25 Revenue Bond Index, a widely followed measure of
longer-term municipal market rates, was 5.14% at the end of March 2006, an
increase of just 11 basis points from the beginning of April 2005. As interest
rates increased, bond valuations generally declined, and the yield curve
flattened as shorter-term rates approached the levels of longer-term rates.

Even with rising interest rates, increased energy prices, and a housing market
that gave some indications of softening, the economy remained resilient, with a
healthy pattern of growth. After expanding at a rate of 3.3% in the second
quarter of 2005, the U.S. gross domestic product (GDP) grew by 4.1% in the third
quarter before slowing to 1.7% in the fourth quarter (all GDP numbers are
annualized). In the first quarter of 2006, the GDP rebounded to 4.8%, fueled by
the return of consumer and federal spending and increased business investment in
equipment. The overall employment picture remained positive, with national
unemployment at 4.7% in March 2006, down from 5.1% in March 2005. Despite a
slight increase in inflation expectations, the year-over-year increase in the
Consumer Price Index as of March 2006 remained relatively benign, at 3.4%.
However, for the first three months of 2006, inflation rose at the slightly
faster pace of 4.3% annualized, compared with 3.4% for all of 2005.


                                       4



Over the 12 months ended March 2006, municipal bond supply nationwide remained
relatively strong, as $403.6 billion in new securities came to market, down 1.5%
from the previous 12 months. However, following record levels of issuance in
calendar year 2005, we saw a dramatic drop-off in supply during the first three
months of 2006, when municipal issuance totaled $69.6 billion, a decrease of 29%
from the same period in 2005. During the first quarter of 2006, the
transportation and education sectors and general purpose bonds experienced the
largest drops in issuance. A major factor in the 2006 YTD decline has been the
sharp reduction in pre-refunding volume, which was off 55% from last year's
levels. Although interest rates remained favorable for refundings, most
borrowers already had ample opportunities to come to the market during 2005.
Overall, demand for municipal bonds remained strong and diversified during this
period.


WHAT KEY STRATEGIES WERE USED TO MANAGE NIM DURING THE 12 MONTHS ENDED MARCH 31,
2006?

As interest rates rose and the yield curve flattened during this period, our key
strategies continued to include careful duration1 management and yield curve
positioning. On the whole, bonds in the intermediate range of the yield curve
were the most negatively impacted by changes in the curve over this period. As a
result, these bonds generally underperformed bonds with longer durations as well
as the municipal market as a whole, with issues having the longest durations (22
years and longer) posting the best returns for the period. This environment
presented some challenges for NIM, which--in keeping with its investment
parameters--maintains a maximum average maturity of 15 years for portfolio
holdings.

Consequently, our purchase activity during this period focused mainly on the
longer end of the range of bonds we could purchase for the Fund, that is, bonds
maturing in 10 to 20 years. In addition to helping us position NIM's duration
more advantageously in the current environment, we believed that bonds in this
part of the yield curve generally offered more attractive opportunities and the
best values. During this period, we also reinvested proceeds from called bonds
and sinking fund payments in the 10- to 20-year part of the curve, which helped
to improve NIM's overall call protection profile.

In looking for potential purchase candidates, we kept an opportunistic eye
toward all types of issuance that we believed could add value to NIM's
portfolio. Because NIM entered this reporting period fully invested and with
routine bond call exposure, the sharp



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.


                                       5



decline in supply during the last three months of this period had little impact
on our purchase activity or on our ability to keep the Fund fully invested.

During this period, the types of bonds we sought for NIM were generally more
defensive, including higher coupon bonds that can help to protect the Fund from
interest rate risk by providing a "cushion" of additional income if rates
continue to rise. For the most part, we also focused on purchasing higher
quality bonds (i.e., AAA and AA rated). In our opinion, NIM's current exposure
to bonds rated BBB or lower and nonrated bonds is at an appropriate level for
the Fund, and our goal during this period was to maintain, but not expand, that
exposure.

Overall, NIM continued to be well diversified geographically. During this
period, we purchased additional paper issued in specialty states, particularly
Florida, Kentucky, and Colorado, where we found attractively priced
opportunities. Because of the higher tax levels in many of these specialty
states, these bonds are generally in great demand by retail investors, which
helps to support their value.

2    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 index do not reflect any expenses.

3    The Lipper General and Insured Unleveraged Municipal Debt Funds category
     average is calculated using the returns of all closed-end exchange-traded
     funds in this category for each period as follows: 1 year, 8; 5 years, 8;
     and 10 years, 8. Fund and Lipper returns assume reinvestment of dividends.


                                       6



For the 12 months ended March 31, 2006, the total return on net asset value
(NAV) for NIM outperformed the return for its Lehman Brothers benchmark. Due in
part to its intermediate-term orientation, NIM underperformed the average return
for the Lipper peer group, which consists predominately of longer-term funds.
This was especially relevant during this reporting period, when the longest
bonds posted the best returns.

During this reporting period, factors having an impact on NIM's return included
yield curve and duration positioning, allocations to lower-rated credits, and
security-specific issues such as advance refundings4 and credit spreads.

As the yield curve continued to flatten over the course of this period, yield
curve and duration positioning played an important role in NIM's performance. As
noted earlier, intermediate bonds were the most impacted by the recent changes
in the yield curve and generally underperformed longer bonds. While NIM
maintained its intermediate-term orientation, our trading activity over the past
12 months, which emphasized bonds at the longer-end of the maturity range we can
purchase for this Fund, helped NIM's performance for the period.

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 and caused credit spreads to tighten. As of
March 31, 2006, bonds rated BBB or lower and nonrated bonds accounted for 19% of
NIM's portfolio. NIM's heavy exposure to this sector of the market contributed
to its outperformance of the Lehman Brothers 7-Year Municipal Bond Index, which
has a smaller allocation of lower-rated bonds.

Among the lower-rated holdings making contributions to NIM's total return for
this period were healthcare (including hospital) bonds, charter schools, tax
incremental finance districts, and tobacco credits. As of March 31, 2006, NIM
held approximately 4% of its portfolio in unenhanced, uninsured tobacco bonds,
which were among the top performing sectors for 2005. In terms of total return
performance for this reporting period, the top three holdings in NIM's portfolio
were Iowa Tobacco Settlement Authority, which was rated BBB prior to refunding;
BBB rated Badger Tobacco Asset Securitization Corporation


4    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.


                                       7



bonds (Wisconsin); and bonds issued by the Northwest Parkway Public Highway
Authority (Colorado).

We also continued to see a number of advance refundings during this period,
which benefited NIM through price appreciation and enhanced credit quality.
Approximately 3% of the Fund's portfolio was advance-refunded during this
period, including our $1.8 million position in tobacco credits issued by the
Iowa Tobacco Settlement Authority; and $515,000 in bonds issued by the Illinois
Health Facilities Authority for Silver Cross Hospital and Medical Centers.

While advance refundings generally enhanced performance for this 12-month
period, the rising interest rate environment--especially at the short-end of the
yield curve--meant that NIM's holdings of older, previously pre-refunded bonds
tended to underperform the general municipal market, due primarily to the
shorter effective maturities of these bonds.

HOW WAS NIM POSITIONED IN TERMS OF CREDIT QUALITY AND BOND CALLS AS OF MARCH 31,
2006?

We continued to believe that maintaining strong overall credit quality was an
important requirement. As of March 31, 2006, NIM continued to offer excellent
credit quality, with 66% of its portfolio allocated to bonds rated AAA/U.S.
guaranteed and AA and another 15% in bonds rated A.

As of March 31, 2006, 6% of NIM's portfolio was subject to potential bond calls
during the period April 2006 through the end of 2007. NIM continued to hold
these callable bonds in part due to their income and performance potential. The
number of actual bond calls will depend largely on future market interest rates.

Dividend and Share Price
     INFORMATION

NIM was able to maintain a stable dividend throughout this 12-month reporting
period. In addition, due to capital gains generated by normal portfolio
activity, NIM's shareholders received a net ordinary income distribution of
$0.0014 per share at the end of December 2005.

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, 2006, NIM had a positive UNII balance for tax
purposes and a negative UNII balance for financial statement purposes.

At the end of the reporting period on March 31, 2006, NIM was trading at a
discount of -1.97% to its NAV. By comparison, the Fund's average discount over
the entire 12-month reporting period was -4.24%.

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, 2006, 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, 2006, by correspondence with the custodian. 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, 2006, 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.

                              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 or, in the absence of a pricing service for a
particular security, the Board of Trustees of the Funds, or its designee, may
establish fair market value using a wide variety of market data including yields
or prices of municipal bonds of comparable quality, type of issue, coupon,
maturity and rating, market quotes or indications of value from securities
dealers, evaluations of anticipated cash flows or collateral, general market
conditions and other information and analysis, including the obligor's credit
characteristics considered relevant by the pricing service or the Board of
Trustees' designee. 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 or 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 and delayed delivery purchase commitments. At March 31, 2006, 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. All monthly
tax-exempt income dividends paid during the fiscal year ended March 31, 2006,
have been designated Exempt Interest Dividends. 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 may 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 make any such
investments during the fiscal year ended March 31, 2006.

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

During the fiscal year ended March 31, 2006, 1,429 shares were issued to
shareholders due to reinvestment of distributions. The Fund did not engage in
transactions in its own shares during the fiscal year ended March 31, 2005.

3. INVESTMENT TRANSACTIONS

Purchases and sales (including maturities but excluding short-term investments)
during the fiscal year ended March 31, 2006, aggregated $8,829,620 and
$8,609,210, 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.

At March 31, 2006, the cost of investments was $121,317,441.

Gross unrealized appreciation and gross unrealized depreciation of investments
at March 31, 2006, were as follows:


--------------------------------------------------------------------------------
Gross unrealized:
   Appreciation                                                      $3,388,557
   Depreciation                                                        (613,995)
--------------------------------------------------------------------------------
Net unrealized appreciation (depreciation) of investments            $2,774,562

                        Notes to
                            FINANCIAL STATEMENTS (continued)


The tax components of undistributed net investment income and net realized gains
at March 31, 2006, were as follows:

--------------------------------------------------------------------------------

Undistributed net tax-exempt income *                                   $353,483
Undistributed net ordinary income **                                      63,950
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, 2006, paid on April 3, 2006.
**   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,
2006 and March 31, 2005, was designated for purposes of the dividends paid
deduction as follows:

2006
--------------------------------------------------------------------------------
Distributions from net tax-exempt income                              $5,875,503
Distributions from net ordinary income **                                 17,355
Distributions from net long-term capital gains ***                            --
================================================================================

2005
--------------------------------------------------------------------------------
Distributions from net tax-exempt income                              $5,875,221
Distributions from net ordinary income **                                 29,748
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 Funds designated as a long-term capital gain dividend, pursuant to
     Internal Revenue Code Section 852(b)(3), the amount necessary to reduce the
     earnings and profits of the Fund related to net capital gain to zero for
     the tax period ended March 31, 2006.

At March 31, 2006, the Fund had unused capital loss carryforwards of $15,295,532
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 and $14,448 will expire in 2014.

The Fund elected to defer $5,016 of net realized losses from investments
incurred from November 1, 2005 through March 31, 2006 ("post-October losses") in
accordance with Federal income tax regulations. The post-October losses were
treated as having arisen on the first day of the following fiscal year.

5. MANAGEMENT FEE 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., 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 the 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, 2006, the complex-level fee rate was .1887%.

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
     all types of leverage used 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. SUBSEQUENT EVENT - DISTRIBUTIONS TO SHAREHOLDERS

The Fund declared a dividend distribution of $.0395 per share from its
tax-exempt net investment income which was paid on May 1, 2006, to shareholders
of record on April 15, 2006.

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 EXCHANGE-TRADED CLOSED-END FUNDS
DIVIDEND REINVESTMENT PLAN

Your Nuveen Exchange-Traded 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
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. 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.

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.

CEO CERTIFICATION DISCLOSURE

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 all the maturities of the bonds in a
Fund's portfolio, computed by weighting each maturity date (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.

MODIFIED 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.

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 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).

The above "All Other Fees" are fees paid to audit firms to perform agreed upon
procedures required by the rating agencies to rate fund preferred shares. The
above "Tax Fees" were billed for professional services for tax advice, tax
compliance, and tax planning.


                 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

The above "Tax Fees" are primarily fees billed to the Adviser for Nuveen
Closed-End Funds tax return preparation.

(1) "Tax Fees Billed to Adviser and Affiliated Fund Service Providers" for the
year ended 3/31/05 have been revised and primarily reflect fees billed to the
Adviser for Nuveen Closed-End Funds tax return preparation.


                               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. For
engagements entered into on or after May 6, 2003, 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.

The above "Non-Audit Fees billed to Adviser" for both fiscal year ends include
"Tax Fees" billed to Adviser in their respectable amounts from the previous
table.

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

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

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 and Eugene S. Sunshine.

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.

THE PORTFOLIO MANAGER

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

NAME                                    FUND
John V. Miller                          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
--------------------------------------------------------------------------------
John V. Miller      Registered Investment Company          4      $3,641 million
                    Other Pooled Investment Vehicles       2      $39.1 million
                    Other Accounts                         8      $1.2 million

*    Assets are as of March 31, 2006. None of the assets in these accounts are
     subject to an advisory fee based on performance.

Compensation. The 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 the 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 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 May 31, 2006, the S&P/Investortools Municipal Bond index was
comprised of 46,877 securities with an aggregate current market value of $879
billion.

Base salary. The 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. The portfolio manager is also eligible to receive an annual cash
bonus. The level of this bonus is based upon evaluations and determinations made
by the 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. The 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. The 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, 2006, 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.

ITEM 9. PURCHASES OF EQUITY SECURITIES BY CLOSED-END MANAGEMENT INVESTMENT
COMPANY AND AFFILIATED PURCHASERS.

Not applicable.

ITEM 10. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

During this reporting period, the registrant's Board of Trustees implemented a
change to the procedures by which shareholders may recommend nominees to the
registrant's board of trustees by amending the registrant's by-laws to include a
provision specifying the date by which shareholder nominations for election as
trustee at a subsequent meeting must be submitted to the registrant.
Shareholders must deliver or mail notice to the registrant not less than
forty-five days nor more than sixty days prior to the first anniversary date of
the date on which the registrant first mailed its proxy materials for the prior
year's annual meeting; provided, however, if and only if the annual meeting is
not scheduled to be held within a period that commences thirty days before the
first anniversary date of the annual meeting for the preceding year and ends
thirty days after such anniversary date (an annual meeting date outside such
period being referred to as an "Other Annual Meeting Date" hereafter), the
shareholder notice must be given no later than the close of business on the date
forty-five days prior to such Other Annual Meeting Date or the tenth business
day following the date such Other Annual Meeting Date is first publicly
announced or disclosed. The shareholder's notice must be in writing and set
forth the name, age, date of birth, business address, residence address and
nationality of the person(s) being nominated and the class or series, number of
all shares of the registrant owned of record or beneficially be each such
person(s), any other information regarding such person required by Item 401 of
Regulation S-K or Item 22 of Rule 14a-101 (Schedule 14A) under the Securities
Exchange Act of 1934, as amended, any other information regarding the person(s)
to be nominated that would be required to be disclosed in a proxy statement or
other filings required to be made in connection with solicitation of proxies for
election of trustees, and whether such shareholder believes any nominee is or
will be an "interested person" (as that term is defined in the Investment
Company Act of 1940, as amended) of the registrant or sufficient information to
enable the registrant to make that determination and the written and signed
consent of the person(s) to be nominated.

ITEM 11. CONTROLS AND PROCEDURES.

     (a)  The registrant's principal executive and principal financial officers,
          or persons performing similar functions, have concluded that the

          "1940 Act") (17 CFR 270.30a-3(c))) are effective, as of a date within
          90 days of the filing date of this report that includes the disclosure
          required by this paragraph, based on their evaluation of the controls
          and procedures required by Rule 30a-3(b) under the 1940 Act (17 CFR
          270.30a-3(b)) and Rules 13a-15(b) or 15d-15(b) under the Securities
          Exchange Act of 1934, as amended (the "Exchange Act")
          (17 CFR 240.13a-15(b) or 240.15d-15(b)).

     (b)  There were no changes in the registrant's internal control over
          financial reporting (as defined in Rule 30a-3(d) under the 1940 Act
          (17 CFR 270.30a-3(d)) that occurred during the second fiscal quarter
          of the period covered by this report that has materially affected, or
          is reasonably likely to materially affect, the registrant's internal
          control over financial reporting.
