Sincerely, /s/ Timothy R. Schwertfeger Timothy R. Schwertfeger Chairman of the Board May 15, 2007 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. 5 HOW DID THE FUND PERFORM? Results for NIM, as well as relevant index information, are presented in the accompanying table. TOTAL RETURNS ON NET ASSET VALUE For periods ended 3/31/07 ANNUALIZED ------------------------------------------ 1-YEAR 5-YEAR 10-YEAR -------------------------------------------------------------------------------- NIM 5.10% 4.27% 4.05% -------------------------------------------------------------------------------- Lehman Brothers 7-Year Municipal Bond Index3 5.06% 4.88% 5.33% -------------------------------------------------------------------------------- Past performance is not predictive of future results. Current performance may be higher or lower than the data shown. Returns do not reflect the deduction of taxes that shareholders may have to pay on Fund distributions or upon the sale of Fund shares. For additional information, see the Performance Overview page for NIM in this report. 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%. 8 Nuveen Select Maturities Municipal Fund NIM Performance OVERVIEW As of March 31, 2007 NIM Pie Chart: CREDIT QUALITY (as a % of total investments) AAA/U.S. Guaranteed 65% AA 5% A 18% BBB 8% BB or Lower 1% N/R 3% Bar Chart: 2006-2007 MONTHLY TAX-FREE DIVIDENDS PER SHARE2 Apr 0.0395 May 0.0395 Jun 0.0395 Jul 0.0395 Aug 0.0395 Sep 0.038 Oct 0.038 Nov 0.038 Dec 0.038 Jan 0.038 Feb 0.038 Mar 0.0365 Line Chart: SHARE PRICE PERFORMANCE Weekly Closing Price Past performance is not predictive of future results. 4/01/06 9.96 9.83 9.47 9.72 10.01 9.73 9.73 9.76 9.88 9.94 9.67 9.6 9.5 9.52 9.56 9.5 9.59 9.67 9.71 9.62 9.76 9.82 9.68 9.7 9.62 9.66 9.75 9.83 9.75 9.69 9.78 9.7 9.74 9.75 9.7599 9.86 9.99 9.92 9.76 9.87 9.83 9.81 10 9.87 9.88 9.9296 9.86 10.03 9.96 9.94 9.87 9.89 9.87 9.9 9.9 9.94 3/31/07 9.94 FUND SNAPSHOT ------------------------------------ Share Price $9.94 ------------------------------------ Net Asset Value $10.19 ------------------------------------ Premium/(Discount) to NAV -2.45% ------------------------------------ Market Yield 4.41% ------------------------------------ Taxable-Equivalent Yield1 6.13% ------------------------------------ Net Assets ($000) $126,316 ------------------------------------ Average Effective Maturity on Securities (Years) 11.05 ------------------------------------ Modified Duration 4.15 ------------------------------------ AVERAGE ANNUAL TOTAL RETURN (Inception 9/18/92) ------------------------------------ ON SHARE PRICE ON NAV ------------------------------------ 1-Year 4.75% 5.10% ------------------------------------ 5-Year 4.30% 4.27% ------------------------------------ 10-Year 4.33% 4.05% ------------------------------------ STATES (as a % of total investments) ------------------------------------ Colorado 13.7% ------------------------------------ Illinois 11.7% ------------------------------------ New York 9.2% ------------------------------------ Pennsylvania 7.9% ------------------------------------ South Carolina 6.6% ------------------------------------ Texas 5.9% ------------------------------------ Florida 4.7% ------------------------------------ Arkansas 4.2% ------------------------------------ Washington 4.1% ------------------------------------ Wisconsin 3.9% ------------------------------------ Kansas 3.0% ------------------------------------ Iowa 2.4% ------------------------------------ Alabama 2.2% ------------------------------------ Michigan 1.8% ------------------------------------ Tennessee 1.8% ------------------------------------ California 1.7% ------------------------------------ Connecticut 1.7% ------------------------------------ West Virginia 1.7% ------------------------------------ Other 11.8% ------------------------------------ INDUSTRIES (as a % of total investments) ------------------------------------ Utilities 19.2% ------------------------------------ U.S. Guaranteed 18.3% ------------------------------------ Health Care 11.3% ------------------------------------ Tax Obligation/Limited 10.4% ------------------------------------ Tax Obligation/General 8.9% ------------------------------------ Transportation 5.7% ------------------------------------ Consumer Staples 5.0% ------------------------------------ Long-Term Care 4.8% ------------------------------------ Education and Civic Organizations 4.7% ------------------------------------ Other 11.7% ------------------------------------ 1 Taxable-Equivalent Yield represents the yield that must be earned on a fully taxable investment in order to equal the yield of the Fund on an after-tax basis.

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. /s/ Ernst & Young LLP Chicago, Illinois May 21, 2007 10 Nuveen Select Maturities Municipal Fund (NIM) Portfolio of INVESTMENTS March 31, 2007 PRINCIPAL OPTIONAL CALL AMOUNT (000) DESCRIPTION PROVISIONS (1) RATINGS (2) VALUE ------------------------------------------------------------------------------------------------------------------------------------ ALABAMA - 2.1% $ 2,000 Alabama 21st Century Authority, Tobacco Settlement Revenue 12/11 at 101.00 A- $ 2,131,220 Bonds, Series 2001, 5.750%, 12/01/17 500 Marshall County Healthcare Authority, Alabama, Revenue 1/12 at 101.00 A- 544,205 Bonds, Series 2002A, 6.250%, 1/01/22 ------------------------------------------------------------------------------------------------------------------------------------ 2,500 Total Alabama 2,675,425 ------------------------------------------------------------------------------------------------------------------------------------ ARIZONA - 0.8% 445 Phoenix Industrial Development Authority, Arizona, Statewide 4/08 at 101.50 AAA 456,971 Single Family Mortgage Revenue Bonds, Series 1998C, 6.650%, 10/01/29 (Alternative Minimum Tax) 515 Winslow Industrial Development Authority, Arizona, Hospital No Opt.

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 ================================================================================ 21 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. 7. SUBSEQUENT EVENT Distributions to Shareholders The Fund declared a dividend distribution of $.0365 per share from its tax-exempt net investment income which was paid on May 1, 2007, to shareholders of record on April 15, 2007. 23 Financial HIGHLIGHTS Selected data for a share outstanding throughout each period: INVESTMENT OPERATIONS LESS DISTRIBUTIONS ------------------------------------- ----------------------------------- NET BEGINNING NET REALIZED/ NET ENDING ENDING NET ASSET INVESTMENT UNREALIZED INVESTMENT CAPITAL NET ASSET MARKET VALUE INCOME GAIN (LOSS) TOTAL INCOME GAINS TOTAL VALUE VALUE ------------------------------------------------------------------------------------------------------------------------------------ Year Ended 3/31: 2007 $10.15 $.46 $ .05 $.51 $(.47) $ -- $(.47) $10.19 $ 9.94 2006 10.22 .48 (.07) .41 (.48) -- (.48) 10.15 9.95 2005 10.35 .49 (.14) .35 (.48) -- (.48) 10.22 9.30 2004 10.34 .51 -- .51 (.50) -- (.50) 10.35 9.93 2003(a) 10.57 .43 (.22) .21 (.44) -- (.44) 10.34 9.85 Year Ended 5/31: 2002 11.21 .57 (.57) -- (.61) (.03) (.64) 10.57 10.45 ==================================================================================================================================== TOTAL RETURNS RATIOS/SUPPLEMENTAL DATA -------------------------- ---------------------------------------------------------------------------------- RATIOS TO AVERAGE RATIOS TO AVERAGE NET ASSETS NET ASSETS BEFORE CREDIT AFTER CREDIT** ------------------------ ----------------------- BASED ON BASED ON ENDING NET NET PORTFOLIO MARKET NET ASSET NET ASSETS INVESTMENT INVESTMENT TURNOVER VALUE+ VALUE+ (000) EXPENSES INCOME EXPENSES INCOME RATE ------------------------------------------------------------------------------------------------------------------------------------ Year Ended 3/31: 2007 4.75% 5.10% $126,316 .62% 4.44% .58% 4.48% 15% 2006 12.21 4.02 125,857 .59 4.67 .57 4.68 7 2005 (1.52) 3.44 126,645 .61 4.81 .60 4.82 10 2004 6.03 5.09 128,335 .63 4.92 .62 4.93 13 2003(a) (1.48) 2.03 128,106 .65* 4.95* .65* 4.96* 6 Year Ended 5/31: 2002 1.87 (.06) 130,959 .69 5.23 .68 5.23 48 ==================================================================================================================================== * Annualized. ** After custodian fee credit. + Total Return on Market Value is the combination of changes in the market price per share and the effect of reinvested dividend income and reinvested capital gains distributions, if any, at the average price paid per share at the time of reinvestment.

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.

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. 34 Other Useful INFORMATION QUARTERLY PORTFOLIO OF INVESTMENTS AND PROXY VOTING INFORMATION The Fund's (i) quarterly portfolio of investments, (ii) information regarding how the Fund voted proxies relating to portfolio securities held during the 12-month period ended June 30, 2006, and (iii) a description of the policies and procedures that the Fund used to determine how to vote proxies relating to portfolio securities are available without charge, upon request, by calling Nuveen Investments toll-free at (800) 257-8787 or on Nuveen's website at www.nuveen.com.

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). SERVICES THAT THE FUND'S AUDITOR BILLED TO THE FUND AUDIT FEES BILLED AUDIT-RELATED FEES TAX FEES ALL OTHER FEES FISCAL YEAR ENDED TO FUND (1) BILLED TO FUND (2) BILLED TO FUND (3) BILLED TO FUND (4) ------------------------------------------------------------------------------------------------------------------------- March 31, 2007 $ 9,674 $ 0 $ 0 $ 0 ------------------------------------------------------------------------------------------------------------------------- Percentage approved 0% 0% 0% 0% pursuant to pre-approval exception ------------------------------------------------------------------------------------------------------------------------- March 31, 2006 $ 9,192 $ 0 $ 405 $ 0 ------------------------------------------------------------------------------------------------------------------------- Percentage approved 0% 0% 0% 0% pursuant to pre-approval exception ------------------------------------------------------------------------------------------------------------------------- (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.

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. FISCAL YEAR ENDED TOTAL NON-AUDIT FEES BILLED TO ADVISER AND AFFILIATED FUND SERVICE TOTAL NON-AUDIT FEES PROVIDERS (ENGAGEMENTS BILLED TO ADVISER AND RELATED DIRECTLY TO THE AFFILIATED FUND SERVICE TOTAL NON-AUDIT FEES OPERATIONS AND FINANCIAL PROVIDERS (ALL OTHER BILLED TO FUND REPORTING OF THE FUND) ENGAGEMENTS) TOTAL ------------------------------------------------------------------------------------------------------------------ March 31, 2007 $ 0 $ 0 $ 0 $ 0 March 31, 2006 $ 405 $ 2,400 $ 0 $ 2,805 "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. ---------------------------------------------------------------------------------------------------------------------- DOLLAR RANGE OF EQUITY DOLLAR RANGE OF SECURITIES BENEFICIALLY OWNED EQUITY SECURITIES IN THE REMAINDER OF NUVEEN BENEFICIALLY OWNED FUNDS MANAGED BY NAM'S NAME OF PORTFOLIO MANAGER FUND IN FUND MUNICIPAL INVESTMENT TEAM ---------------------------------------------------------------------------------------------------------------------- Paul Brennan Nuveen Select Maturities Municipal Fund $0 $50,001-$100,000 ---------------------------------------------------------------------------------------------------------------------- PORTFOLIO MANAGER BIO: Paul Brennan, CFA, CPA, became a portfolio manager of Flagship Financial Inc. in 1994, and subsequently became an Assistant Vice President of NAM upon the acquisition of Flagship Resources Inc. by Nuveen in 1997. He became Vice President of NAM in 2002. He currently manages investments for 15 Nuveen-sponsored investment companies. ITEM 9.
