Schwertfeger Chairman of the Board Sidebar text: WE THINK YOUR NUVEEN FUND CAN BE AN IMPORTANT BUILDING BLOCK IN A PORTFOLIO DESIGNED TO PERFORM WELL THROUGH A VARIETY OF MARKET CONDITIONS. Dear SHAREHOLDER I am very pleased to report that for the six-month period ended September 30, 2003, your Nuveen Fund continued to provide you with attractive monthly tax- free income. Your Nuveen Fund is managed with a value investing strategy that puts an emphasis on finding securities that we think are undervalued or underrated. We believe that there are always some municipal bonds that the market is not properly valuing, and that by using a consistent, research-oriented management approach we have the opportunity to find them for your Fund. We think this is true even with interest rates at the relatively low levels we've seen over much of the past year. In this low-rate environment, many have begun to wonder whether interest rates will soon start to rise, and whether that possibility should cause them to adjust their holdings of fixed-income investments. We believe that by constructing a carefully balanced portfolio with the help of a trusted investment professional you may be able to reduce your overall investment risk and give yourself a better chance to meet your financial goals. We think that municipal bond investments like your Nuveen Fund can be important building blocks in a portfolio designed to perform well through a variety of market conditions. Since 1898, Nuveen Investments has offered financial products and solutions that incorporate careful research, diversification, and the application of conservative risk-management principles. We are grateful that you have chosen us as a partner as you pursue your financial goals. We look forward to continuing to earn your trust in the months and years ahead. Sincerely, /s/ Timothy R. Schwertfeger Timothy R. Schwertfeger Chairman of the Board November 15, 2003 1 Nuveen Select Maturities Municipal Fund (NIM) Portfolio Manager's COMMENTS Portfolio manager John Miller reviews economic and market conditions, key investment strategies, and the Fund's recent performance. With nine years of municipal market experience, John has managed NIM since 2001. WHAT FACTORS AFFECTED THE U.S. ECONOMY AND MUNICIPAL MARKET DURING THE 12-MONTH PERIOD ENDED SEPTEMBER 30, 2003? Over the 12-month period, the two greatest influences on the general economy and the municipal market continued to be historically low interest rates and the slow pace of economic improvement. In June 2003, the Federal Reserve cut the fed funds rate to 1%, the lowest level since 1958. Much of the recent concern about economic recovery centered on the weak labor market--as of September 2003, U.S. unemployment was 6.1%, up from 5.7% 12 months earlier. At the same time, inflation remained dormant, with the 12-month advance in the core rate dropping to 1.2% in September. The slow rate of economic recovery, low interest rates, and lack of inflationary pressures helped many municipal bonds perform well over the majority of this reporting period. During the summer of 2003, however, stronger-than-expected economic data temporarily precipitated a spike in bond yields and a corresponding drop in bond prices that impacted overall results across all fixed-income markets, for the 12-month period ended September 30, 2003. One barometer of the recent volatility in the bond markets was the yield on the benchmark 10-year U.S. Treasury, which jumped almost 150 basis points from a 45-year low of 3.10% in mid-June to a 13-month high of 4.59% in mid-August. During January-September 2003, municipal supply nationally remained robust, with $287 billion in new bonds--up 13% over the same period in 2002. HOW DID NIM PERFORM OVER THIS 12-MONTH PERIOD? Results for this Fund, as well as relevant benchmarks, are presented in the accompanying table. TOTAL RETURN LEHMAN LIPPER MARKET YIELD ON NAV TOTAL RETURN1 AVERAGE2 ------------------------------------------------------------------------ 1 YEAR 1 YEAR 1 YEAR TAXABLE- ENDED ENDED ENDED 9/30/03 EQUIVALENT3 9/30/03 9/30/03 9/30/03 ------------------------------------------------------------------------ NIM 5.10% 7.08% 2.40% 4.71% 3.35% ------------------------------------------------------------------------ Past performance is not predictive of future results. For additional information, see the individual Performance Overview for your Fund in this report. For the 12 months ended September 30, 2003, the performance of NIM lagged that of both the Lehman Brothers 7-Year Municipal Bond Index and the Fund's Lipper peer group. The majority of the underperformance can be attributed to a few specific holdings within the Fund. The price movement of specific sectors and holdings also had a negative impact on the Fund's 1 The total annual return on common share net asset value (NAV) for NIM is compared with the total annual return of the Lehman Brothers 7-Year Municipal Bond Index, an unleveraged, unmanaged 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. 2 The total return for NIM is compared with the average annualized return of the nine funds in the Lipper General and Insured Unleveraged Municipal Debt Funds category. Fund and Lipper returns assume reinvestment of dividends. 3 Taxable-equivalent yield represents the yield that must be earned on a taxable investment, other than an investment that generates qualified dividend income that is taxable at the maximum rate of 15%, in order to equal the yield of the Nuveen Fund on an after-tax basis. It is calculated using the current yield and a federal income tax rate of 28%. 2 performance during this period. For example, at the beginning of this period, NIM held $4.5 million par value in bonds issued for a maintenance facility at Tulsa Municipal Airport and backed by American Airlines. These bonds depreciated significantly over the past two years as American and most other airlines struggled with the economic downturn and the aftermath of September 11, 2001. Although we liquidated NIM's position as of March 2003, the depreciation of the American bonds cost the Fund approximately 80 basis points in total return performance over this period. NIM also held approximately 5% of its portfolio in tobacco bonds. Over the past year, the prices of tobacco bonds weakened. In July 2003, the credit ratings on most tobacco bonds were downgraded to BBB, and the sector as a whole produced negative results for the 12 months ended September 30, 2003, costing NIM approximately 30 basis points in performance for this period. Recently, however, these bonds have shown some recovery. Following an in-depth analysis of the tobacco sector, we believe that ongoing litigation will not affect the long-term quality and value provided by the tobacco settlement bonds. Other holdings that impacted NIM's performance over the past 12 months included $5 million par in bonds issued for CanFibre of Lackawanna in New York and $1.2 million par in bonds issued for Winslow Memorial Hospital in Arizona. Although we closed out NIMposition in the CanFibre bonds in February 2003, the decline in those bonds over the previous five months cost the Fund an additional 30 basis points in performance. The Fund maintained its investment in Winslow Memorial Hospital, which depreciated in value as the hospital experienced financial and management difficulties, costing NIM 18 basis points over this reporting period. With new management in place, Winslow is currently working to resolve problems and achieve a potential turnaround. NIM's 27% weighting in BBB and non-rated bonds also contributed to its lag in performance over this period, as higher quality bonds performed better in the market. HOW DID THE MARKET ENVIRONMENT AFFECT THE FUND'S DIVIDENDS AND SHARE PRICES? Due to the sale of distressed credits as previously discussed, as well as a number of bond calls over the 12 month period, NIM was faced with reinvesting a substantial amount of proceeds from higher-coupon bonds into a market where short-term interest rates remained at historically low levels. This led to a reduction of the Fund's earning power and necessitated a dividend cut in June 2003. 3 NIM's discount to its common share NAV narrowed modestly (see chart on individual Performance Overview page). WHAT KEY STRATEGIES WERE USED TO MANAGE NIM DURING THE 12 MONTHS ENDED SEPTEMBER 30, 2003? Over this 12-month reporting period, we continued to place strong emphasis on strategies that could diversify the Fund's portfolio and improve call protection. Our primary area of focus was on enhancing the Fund's credit quality through purchases of high-quality bonds that would help to extend NIM's duration and support the Fund's dividend-paying capabilities. We believed that, given the current geopolitical and economic climate, maintaining strong credit quality remains a vital requirement. In general, the heavy issuance in the municipal market over the past year increased our opportunities to make trades that could benefit the Fund, as we concentrated on finding value in the intermediate part of the yield curve (bonds that mature 12 to 15 years). WHAT IS YOUR OUTLOOK FOR BOND CALLS FOR NIM? During this reporting period, we continued to work to mitigate the call risk of NIM. As of September 30, 2003, we had worked through the majority of 2003's calls, reducing the Fund's call exposure for this period to 3%. In 2004, NIM faces potential calls on an additional 11% of its portfolio. The number of actual calls will depend largely on market interest rates in coming months. Overall, we have been holding bonds until they are actually called from our portfolio and reinvesting proceeds in higher quality issues at the long end of the maturity spectrum available to NIM. 4 Nuveen Select Maturities Municipal Fund Performance OVERVIEW As of September 30, 2003 NIM Pie Chart: CREDIT QUALITY AAA/U.S. Guaranteed 39% AA 11% A 22% BBB 22% NR 5% BB or lower 1% PORTFOLIO STATISTICS -------------------------------------------------- Share Price $10.00 -------------------------------------------------- Common Share Net Asset Value $10.29 -------------------------------------------------- Market Yield 5.10% -------------------------------------------------- Taxable-Equivalent Yield (Federal Income Tax Rate)1 7.08% -------------------------------------------------- Net Assets Applicable to Common Shares ($000) $127,575 -------------------------------------------------- Average Effective Maturity (Years) 11.47 -------------------------------------------------- Average Duration 4.56 -------------------------------------------------- AVERAGE ANNUAL TOTAL RETURN (Inception 9/18/92) -------------------------------------------------- ON SHARE PRICE ON NAV -------------------------------------------------- 1-Year 3.61% 2.40% -------------------------------------------------- 5-Year 2.81% 2.45% -------------------------------------------------- 10-Year 4.04% 4.18% -------------------------------------------------- TOP FIVE SECTORS (as a % of total investments) -------------------------------------------------- Utilities 20% -------------------------------------------------- Healthcare 20% -------------------------------------------------- Long-Term Care 8% -------------------------------------------------- U.S. Guaranteed 8% -------------------------------------------------- Consumer Staples 7% -------------------------------------------------- Bar Chart: 2002-2003 MONTHLY TAX-FREE DIVIDENDS PER SHARE2 Oct 0.044 Nov 0.044 Dec 0.044 Jan 0.044 Feb 0.044 Mar 0.044 Apr 0.044 May 0.044 Jun 0.0425 Jul 0.0425 Aug 0.0425 Sep 0.0425 Line Chart: SHARE PRICE PERFORMANCE 10/1/02 10.35 10.22 9.9 9.78 10.08 10.19 10.04 9.66 9.8 9.8 9.63 9.55 9.61 9.79 9.6 9.65 9.65 9.82 9.91 9.75 9.74 9.89 9.9 9.88 9.77 9.8 9.94 9.87 9.8 9.87 10.08 10.1 10.29 10.41 10.35 10.1 10.05 10.11 10.19 10.02 9.86 9.85 9.91 9.94 9.87 9.93 10 9.92 9/30/03 9.92 Weekly Closing Price Past performance is not predictive of future results. 1 Taxable-equivalent yield represents the yield that must be earned on a taxable investment, other than an investment that generates qualified dividend income that is taxable at the maximum rate of 15%, in order to equal the yield of the Nuveen Fund on an after-tax basis.

GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The Fund covered in this report and its corresponding Common share 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 having an initial average effective maturity of approximately ten years. 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 Nuveen Advisory Corp. (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc., 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. On February 20, 2003, the Board of Trustees of the Fund approved a change in the Fund's fiscal year end from May 31 to March 31. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements in accordance with accounting principles generally accepted in the United States. Securities 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 price quotes are not readily available (which is usually the case for municipal securities), the pricing service establishes fair market 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 it is determined that market prices for a security are unavailable or inappropriate, the Board of Trustees of the Fund, or its designee, may establish a fair value for the security. Temporary investments in securities that have variable rate and demand features qualifying them as short-term securities are valued at amortized cost, which approximates market value. Securities Transactions Securities transactions are recorded on a trade date basis. Realized gains and losses from such transactions are determined on the specific identification method. Securities purchased or sold on a when-issued or delayed delivery basis may have extended settlement periods. The securities 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 September 30, 2003, 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. Federal Income Taxes The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute all of its net investment income to its shareholders. 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 the shareholders of the Fund. 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. 15 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) 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 accounting principles generally accepted in the United States. 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 six months ended September 30, 2003. 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. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States 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 There were no share transactions during the six months ended September 30, 2003. There were no share transactions during the period June 1, 2002 through March 31, 2003. During the fiscal year ended May 31, 2002, 14,191 shares were issued to shareholders due to reinvestment of distributions. 3. SECURITIES TRANSACTIONS Purchases and sales (including maturities) of investments in long-term municipal securities for the six months ended September 30, 2003, aggregated $12,424,096 and $8,863,561, 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 timing differences in recognizing income on taxable market discount securities and timing differences in recognizing certain gains and losses on security transactions. At September 30, 2003, the cost of investments owned was $118,502,995. The net unrealized appreciation of investments at September 30, 2003, aggregated $4,881,546 of which $6,183,553 related to appreciated securities and $1,302,007 related to depreciated securities. The tax components of undistributed net investment income and net realized gains at March 31, 2003, the Fund's last fiscal year end, were as follows: -------------------------------------------------------------------------------- Undistributed net tax-exempt income $76,094 Undistributed net ordinary income * 19,776 Undistributed net long-term capital gains -- ================================================================================ * Net ordinary income consists of taxable market discount income and net short-term capital gains, if any. 16 The tax character of distributions paid during the fiscal years ended March 31, 2003 and May 31, 2002, was designated for purposes of the dividends paid deduction as follows: 2003 -------------------------------------------------------------------------------- Distributions from net tax-exempt income $5,478,580 Distributions from net ordinary income * 4,958 Distributions from net long-term capital gains -- ================================================================================ 2002 -------------------------------------------------------------------------------- Distributions from net tax-exempt income $7,586,610 Distributions from net ordinary income * 349,903 Distributions from net long-term capital gains -- ================================================================================ * Net ordinary income consists of taxable market discount income and net short-term capital gains, if any. At March 31, 2003, the Fund's last fiscal year end, the Fund had unused capital loss carryforwards of $6,538,308 available to be applied against future capital gains, if any. If not applied, $14,922 of the carryforward will expire in the year 2010 and $6,523,386 will expire in 2011. At March 31, 2003, the Fund's last fiscal year end, the Fund elected to defer net realized losses from investments incurred from November 1, 2002 through March 31, 2003 ("post-October losses") in accordance with Federal income tax regulations. The post-October losses of $8,692,592 are treated as having arisen on the first day of the current fiscal year. 5. MANAGEMENT FEES AND OTHER TRANSACTIONS WITH AFFILIATES Under the Fund's investment management agreement with the Adviser, the Fund pays an annual management fee, payable monthly, at the rates set forth below, which are based upon the average daily net assets of the Fund as follows: AVERAGE DAILY NET ASSETS MANAGEMENT FEE -------------------------------------------------------------------------------- For the first $125 million .5000% For the next $125 million .4875 For the next $250 million .4750 For the next $500 million .4625 For the next $1 billion .4500 For net assets over $2 billion .4375 ================================================================================ 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. 6. INVESTMENT COMPOSITION At September 30, 2003, the revenue sources by municipal purpose, expressed as a percent of total investments, were as follows: -------------------------------------------------------------------------------- Consumer Staples 7% Education and Civic Organizations 5 Healthcare 20 Housing/Multifamily 6 Housing/Single Family 4 Long-Term Care 8 Materials 4 Tax Obligation/General 6 Tax Obligation/Limited 6 Transportation 5 U.S. Guaranteed 8 Utilities 20 Other 1 -------------------------------------------------------------------------------- 100% ================================================================================ In addition, 31% of the total investments owned by the Fund are either covered by insurance issued by several private insurers or are backed by an escrow or trust containing U.S. Government or U.S. Government agency securities, both of which ensure the timely payment of principal and interest in the event of default.

A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT. NUVEEN CLOSED-END EXCHANGE-TRADED FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen Closed-End Exchange-Traded 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 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. FLEXIBILITY 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. For more information on the Nuveen Automatic Reinvestment Plan or to enroll in or withdraw from the Plan, speak with your financial advisor or call us at (800) 257-8787. 20 Fund INFORMATION BOARD OF TRUSTEES William E.

Box 43071 Providence, RI 02940-3071 (800) 257-8787 LEGAL COUNSEL Chapman and Cutler LLP Chicago, IL INDEPENDENT AUDITORS Ernst & Young LLP Chicago, IL 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 (including change in NAV and reinvested dividends) that would have been necessary on an annual basis to equal the investment's actual performance over the time period being considered. Average Duration: Duration is a measure of a bond or bond fund's sensitivity to changes in interest rates. Generally, the longer a bond or fund's duration, the more the price of the bond or fund will change as interest rates change. 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. 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 NAV is calculated by subtracting the liabilities of 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. --------- This Fund intends to repurchase shares of its own common stock in the future at such times and in such amounts as is deemed advisable. No shares were repurchased during the period ended September 30, 2003. Any future repurchases will be reported to shareholders in the next annual or semiannual report. 21 Serving Investors FOR GENERATIONS Since 1898, financial advisors and their clients have relied on Nuveen Investments to provide dependable investment solutions.
