Sincerely, /s/ Timothy R. Schwertfeger Timothy R. Schwertfeger Chairman of the Board November 16, 2006 Nuveen Investments Select Tax-Free Income Portfolios (NXP, NXQ, NXR, NXC, NXN) Portfolio Managers' COMMENTS Portfolio managers Tom Spalding, Scott Romans, and Cathryn Steeves discuss key investment strategies and the six-month performance of the Nuveen Select Portfolios. With 31 years of investment experience, Tom has managed the three national Portfolios since 1999. Scott, who joined Nuveen in 2000, has managed NXC since 2003, while Cathryn, who has been with Nuveen since 1996, assumed portfolio management responsibility for NXN in July 2006. WHAT KEY STRATEGIES WERE USED TO MANAGE THE NUVEEN SELECT PORTFOLIOS DURING THE SIX-MONTH REPORTING PERIOD ENDED SEPTEMBER 30, 2006? During this reporting period, we saw interest rates at the short end of the yield curve continue to rise, while rates across the rest of the curve generally declined. At its May and June 2006 meetings, the Federal Reserve's Open Market Committee announced two additional quarter-point increases in the fed funds rate, raising this short-term target from 4.75% to 5.25%, its highest level since March 2001. At the subsequent August and September sessions, the committee left monetary policy unchanged, marking the first pause in rate increases in more than two years. In contrast, during this same six-month period, the yield on the benchmark 10-year U.S. Treasury note fell 22 basis points to end September 2006 at 4.63%. In the municipal market, the yield on the Bond Buyer 25 Revenue Bond Index, a widely followed measure of longer-term municipal market rates, stood at 4.77% at the end of September 2006, a decline of 37 basis points from the end of March 2006. As short-term rates approached and exceeded the levels of long-term rates, the yield curve continued to flatten and then invert, and bonds with longer durations1 generally outperformed those with shorter durations. As the yield curve became increasingly flat, our focus remained on a disciplined approach to duration management and yield curve positioning. Depending on the varying needs of the Portfolios, our purchase activity during this period emphasized mainly attractively structured, premium coupon2 bonds maturing in 20 to 30 years in the national Portfolios, 20 to 25 years in NXC, and 15 to 25 years in NXN. Overall, we believed that the bonds we purchased during this period offered strong performance potential, good value, and attractive reward opportunities without excessive risk. 1 Duration is a measure of a bond's price sensitivity as interest rates change, with longer duration bonds displaying more sensitivity to these changes than bonds with shorter durations. 2 Premium coupon bonds are credits that, at the time of purchase, are trading above their par values because their coupons are higher than current coupon levels. Historically, these bonds have held their value better than current coupon bonds when interest rates rise. 4 In looking for potential additions to the Portfolios, we kept an opportunistic eye toward all types of issuance that we believed could add value. During this six-month period, new municipal bond supply nationwide totaled $199.9 billion, down 6% from that of April-September 2005. This was part of a larger trend toward declining issuance in 2006, as record levels of new paper in calendar year 2005 were followed by a 16% drop in supply during the first nine months of 2006 compared with the first nine months of 2005. The major factor in 2006's decline was a sharp reduction in pre-refunding volume, which was off more than 54% from last year's levels. In California, municipal issuance for the six months ended September 30, 2006, totaled $25.7 billion, a decrease of 15% from the same period in 2005, while New York saw $18.1 in new supply, down 20% from April-September 2005. Despite the decline in issuance, California and New York continued to rank as the largest state issuers in the nation for this period. Overall, the reduction in supply did not have a major impact on the implementation of strategies we had planned for these Portfolios. In light of tighter municipal supply, the national Portfolios generally looked to states with stronger issuance, including California, New York, Texas, Florida, and Illinois, when searching for potential purchases. We also found selected opportunities in states such as Nebraska and Kansas to purchase healthcare bonds. Overall, these Portfolios remained well diversified geographically. During the early part of this reporting period, we were still finding value in lower-rated issues despite narrowing credit spreads. Toward the end of the period, however, spreads had become so tight that we decided that higher quality bonds, including insured credits, represented better long-term value for these Portfolios. In general, new purchases were funded with proceeds from called housing and pre-refunded bonds rather than proceeds realized through active selling of the Portfolios' older, higher-yielding holdings. If sold, these holdings would have to be replaced with bonds currently available in the market, which generally offered lower yields. 5 During this period, we continued to work on building both NXC and NXN's exposure to bonds rated BBB or lower and nonrated bonds. However, tighter supply and narrowing credit spreads (the difference between the yield of lower-quality bonds and the lower yields of higher-quality bonds) generally meant that we found fewer attractively structured lower-rated credit opportunities. In NXC, we also diversified our exposure to the lower end of the credit spectrum by selling BBB+ bonds issued for Daughters of Charity Health System and buying A+ rated bonds issued by the California Statewide Community Development Authority for the Kaiser Permanente System, which we believed offered better value relative to their fundamental credit quality. As in the national Portfolios, we also took advantage of opportunities to purchase higher-quality securities. Additions to NXN during this period included insured bonds issued by New York City Industrial Development Agency to finance new stadiums for the New York Yankees and Mets as well as insured hospital credits. To help us maintain NXC's and NXN's durations within our preferred strategic range, we selectively sold holdings with shorter durations. These sales also helped us to fund new purchases in these two Portfolios, which had minimal call proceeds to reinvest during this period. In NXC, we also found some opportunities to sell a few of our holdings that were purchased when yields were lower and replace them with similar, newer credits that yielded more. This process allowed us to maintain the Portfolio's current characteristics while strengthening its income stream at the individual position level. 6 HOW DID THE PORTFOLIOS PERFORM? Individual results for the Nuveen Select Portfolios, as well as for relevant indexes and peer groups, are presented in the accompanying table.

The Lehman Brothers Tax-Exempt Bond Indexes for California and New York are also unleveraged and unmanaged and comprise a broad range of municipal bonds issued in California and New York, respectively. Results for the Lehman indexes do not reflect any expenses. 4 Each of the Lipper Municipal Debt Funds averages shown in this report are calculated using the returns of all closed-end funds in their respective categories for each period as follows: Lipper General and Insured Unleveraged category, 6 months, 8; 1 year, 8; 5 years, 8; and 10 years, 8; Lipper California category, 6 months, 26; 1 year, 26; 5 years, 16; and 10 years, 13; and Lipper New York category, 6 months, 20; 1 year, 20; 5 years, 10; and 10 years, 7. Portfolio and Lipper returns assume reinvestment of dividends. The Lipper CAand NY Municipal Debt Funds peer groups are comprised predominantely of leveraged funds. 7 For the six months ended September 30, 2006, the cumulative returns on net asset value (NAV) for NXP, NXQ, and NXR performed in line with the return on the Lehman Brothers Municipal Bond Index, while NXC and NXN exceeded the returns on the Lehman Brothers Tax-Exempt Bond Indexes for California and New York, respectively. The three national Portfolios underperformed the Lipper General and Insured Unleveraged peer group for this period, and NXC and NXN lagged the average returns for their respective Lipper California and New York peer groups. The strong performances of the Lipper peer groups for California and New York were due in part to the fact that, unlike NXC and NXN, the majority of the funds that make up these groups are leveraged. This strategy provides opportunities for enhanced returns accompanied by additional risk exposure. During this reporting period, the returns on the Select Portfolios were influenced by market factors, especially the decline in interest rates at the long end of the yield curve, as well as fund-specific factors, including yield curve and duration positioning, allocations to lower-rated credits, sector allocation, and security-specific characteristics such as advance refundings.5 As longer rates declined and the yield curve flattened over the course of this period, yield curve and duration positioning played an important role in the performance of these Portfolios. Overall, bonds in the Lehman Brothers Municipal Bond Index with maturities of less than eight years, especially those maturing in one to two years, were the most adversely impacted by changes in the interest rate environment over this period. As a result, these bonds generally underperformed bonds with longer durations, with issues having the longest maturities (22 years and longer) achieving the best returns for the period. On the whole, the national Portfolios--NXP, NXQ, and NXR--had relatively heavier exposures to the shorter end of the yield curve, particularly in short pre-refunded bonds, which hindered them from participating fully in the rally at the longer end of the curve as longer-term rates declined. While NXN was also underexposed to the longest part of the curve that performed well, this Portfolio held relatively fewer short bonds and a good allocation of intermediate bonds. This overall positioning benefited NXN's performance. 5 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. 8 With bonds rated BBB or lower and nonrated bonds generally outperforming higher credit quality bonds during this period, the Portfolios also benefited from their allocations 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 September 30, 2006, bonds rated BBB or lower and nonrated bonds accounted for 9% of NXR's portfolio, 10% of NXP's and NXC's portfolios, and 11% of NXQ. NXN's relatively lighter exposure to lower-rated credits (6%) meant that this Portfolio's performance did not benefit to the same extent as the other Portfolios. Among the lower-rated holdings making contributions to the Portfolios' returns for this period were healthcare (including hospitals), industrial development bonds, and tobacco credits. At period end, the national Portfolios each held approximately 5% of their portfolios in bonds backed by the 1998 master tobacco settlement agreement, while NXC and NXN had each allocated approximately 2% to these credits. In addition, NXP, NXQ, NXR, and NXC all had heavy weightings of zero coupon bonds, which were among the top performing credits during this period due to their very long durations. NXC also benefited from its holdings of noncallable bonds. We also continued to see positive contributions from advance refunding activity in NXC and NXN, which benefited these Portfolios through price appreciation and enhanced credit quality. Approximately 8% of NXC's portfolio was advance-refunded during this period, including a $2.6 million position in bonds issued for the University of the Pacific, while NXN had 5% of its portfolio pre-refunded. While advance refundings generally enhanced performance for this six-month period, the Portfolios' holdings of older, previously pre-refunded bonds tended to underperform the general municipal market, due primarily to their shorter effective maturities. This was especially true in NXP, which had the largest allocation of pre-refunded bonds among the three national Portfolios. The general underperformance of shorter maturity bonds also 9 meant that the Portfolios' holdings of short call bonds and bonds that are currently callable did not perform well during this period. HOW WERE THE PORTFOLIOS POSITIONED IN TERMS OF CREDIT QUALITY AND BOND CALLS AS OF SEPTEMBER 30, 2006? Maintaining strong credit quality remained an important requirement for the Portfolios. As of September 30, 2006, these five Portfolios continued to offer excellent credit quality, with allocations of bonds rated AAA/U.S. guaranteed and AA ranging from 72% in NXC, 74% in NXR, 75% in NXP, and 78% in NXQ to 92% in NXN. As of September 30, 2006, potential call exposure for these Portfolios for the period October 2006 through the end of 2008 ranged from 5% in NXR, NXC, and NXN to 9% in NXQ and 10% in NXP. The number of actual bond calls will depend largely on future market interest rates. 10 Dividend and Share Price INFORMATION During the six-month reporting period ended September 30, 2006, the dividends of all five of the Select Portfolios remained stable. All of these Portfolios seek to pay stable dividends at rates that reflect each Portfolio's past results and projected future performance. During certain periods, each Portfolio may pay dividends at a rate that may be more or less than the amount of net investment income actually earned by the Portfolio during the period. If a Portfolio 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 Portfolio's NAV. Conversely, if a Portfolio has cumulatively paid dividends in excess of its earnings, the excess constitutes negative UNII that is likewise reflected in the Portfolio's NAV. Each Portfolio will, over time, pay all of its net investment income as dividends to shareholders. As of September 30, 2006, NXP had a positive UNII balance for financial statement purposes and a positive UNII balance, based on our best estimates, for tax purposes. NXQ, NXR, NXC and NXN each had negative UNII balances for financial purposes and positive UNII balances, based on our best estimates, for tax purposes. As of September 30, 2006, the share prices of the Select Portfolios were trading at discounts to their NAVs as shown in the accompanying chart: 9/30/06 6-MONTH AVERAGE DISCOUNT DISCOUNT

(5) On December 9, 2002, UAL Corporation ("UAL"), the holding company of United Air Lines, Inc. filed for federal bankruptcy protection. The Adviser determined that it was likely that United would not remain current on their interest payment obligations with respect to the bonds previously held and thus the Fund had stopped accruing interest on its UAL bonds. On February 1, 2006, UAL emerged from federal bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement established to meet UAL's unsecured bond obligations, the bondholders, including the Fund, received three distributions of UAL common stock over the subsequent months, and the bankruptcy court dismissed all unsecured claims of bondholders, including those of the Fund. On May 5, 2006, the Fund liquidated such UAL common stock holdings. On September 29, 2006, the Fund received an additional distribution of UAL common stock as a result of its earlier ownership of UAL bonds, which it still held at September 30, 2006. N/R Not rated.

There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. (2) Ratings: Using the higher of Standard & Poor's or Moody's rating. Ratings below BBB by Standard & Poor's Group or Baa by Moody's Investor Service, Inc. are considered to be below investment grade. The ratings shown for inverse floating rate investments represent those of the underlying bonds and not the inverse floating rate investments themselves. Inverse floating rate investments likely present greater credit risk to the holders of such investments than to those holders of the underlying bonds. (3) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities which ensure the timely payment of principal and interest. Such investments are normally considered to be equivalent to AAA rated securities. (4) Investment has a maturity of more than one year, but has variable rate and demand features which qualify it as a short-term investment. The rate disclosed is that in effect at the end of the reporting period. This rate changes periodically based on market conditions or a specified market index. (5) Non-income producing. (6) On December 9, 2002, UAL Corporation ("UAL"), the holding company of United Air Lines, Inc. filed for federal bankruptcy protection. The Adviser determined that it was likely that United would not remain current on their interest payment obligations with respect to the bonds previously held and thus the Fund had stopped accruing interest on its UAL bonds. On February 1, 2006, UAL emerged from federal bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement established to meet UAL's unsecured bond obligations, the bondholders, including the Fund, received three distributions of UAL common stock over the subsequent months, and the bankruptcy court dismissed all unsecured claims of bondholders, including those of the Fund. On May 5, 2006, the Fund liquidated such UAL common stock holdings.

There may be other call provisions at varying prices at later dates. Certain mortgage-backed securities may be subject to periodic principal paydowns. (2) Ratings: Using the higher of Standard & Poor's or Moody's rating. Ratings below BBB by Standard & Poor's Group or Baa by Moody's Investor Service, Inc. are considered to be below investment grade. The ratings shown for inverse floating rate investments represent those of the underlying bonds and not the inverse floating rate investments themselves. Inverse floating rate investments likely present greater credit risk to the holders of such investments than to those holders of the underlying bonds. (3) Backed by an escrow or trust containing sufficient U.S. Government or U.S. Government agency securities which ensure the timely payment of principal and interest.

(6) On December 9, 2002, UAL Corporation ("UAL"), the holding company of United Air Lines, Inc. filed for federal bankruptcy protection. The Adviser determined that it was likely that United would not remain current on their interest payment obligations with respect to the bonds previously held and thus the Fund had stopped accruing interest on its UAL bonds. On February 1, 2006, UAL emerged from federal bankruptcy with the acceptance of its reorganization plan by the bankruptcy court. Under the settlement agreement established to meet UAL's unsecured bond obligations, the bondholders, including the Fund, received three distributions of UAL common stock over the subsequent months, and the bankruptcy court dismissed all unsecured claims of bondholders, including those of the Fund. On May 5, 2006, the Fund liquidated such UAL common stock holdings. On September 29, 2006, the Fund received an additional distribution of UAL common stock as a result of its earlier ownership of UAL bonds, which it still held at September 30, 2006. N/R Not rated.

FINANCIAL STATEMENTS (Unaudited) 1. GENERAL INFORMATION AND SIGNIFICANT ACCOUNTING POLICIES The funds (the "Funds") covered in this report and their corresponding New York Stock Exchange symbols are Nuveen Select Tax-Free Income Portfolio (NXP), Nuveen Select Tax-Free Income Portfolio 2 (NXQ), Nuveen Select Tax-Free Income Portfolio 3 (NXR), Nuveen California Select Tax-Free Income Portfolio (NXC) and Nuveen New York Select Tax-Free Income Portfolio (NXN). The Funds are registered under the Investment Company Act of 1940, as amended, as closed-end, diversified management investment companies. Each Fund seeks to provide stable dividends consistent with the preservation of capital, exempt from regular federal and designated state income taxes, where applicable, by investing primarily in a diversified portfolio of municipal obligations. The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements in accordance with U.S. generally accepted accounting principles. Investment Valuation The prices of municipal bonds in each Fund's investment portfolio are provided by a pricing service approved by the Fund's Board of Trustees. When market price quotes are not readily available (which is usually the case for municipal securities), the pricing service establishes 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 it is determined that the market price or fair market value for an investment is unavailable or inappropriate, the Board of Trustees of the Funds, or its designee, may establish a fair value for the investment. Exchange-listed securities are generally valued at the last sales price on the securities exchange on which such securities are primarily traded. Securities traded on a securities exchange for which there are no transactions on a given day or securities not listed on a securities exchange are valued at the mean of the closing bid and asked prices. Securities traded on Nasdaq are valued at the Nasdaq Official Closing Price. 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 Funds have instructed the custodian to segregate assets with a current value at least equal to the amount of the when issued/delayed delivery purchase commitments. At September 30, 2006, there were no such outstanding purchase commitments in any of the Funds. Investment Income Interest income, which includes the amortization of premiums and accretion of discounts for financial reporting purposes, is recorded on an accrual basis. Investment income also includes paydown gains and losses, if any. Dividend income, if any, is recorded on the ex-dividend date. 50 Income Taxes Each Fund is a separate taxpayer for federal income tax purposes. Each 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, each Fund intends to satisfy conditions which will enable interest from municipal securities, which is exempt from regular federal and applicable state income taxes, if any, to retain such tax-exempt status when distributed to shareholders of the Funds. Net realized capital gains and ordinary income distributions paid by the Funds are subject to federal taxation. 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 Funds are authorized to invest in certain derivative financial instruments including futures, forward, swap and option contracts, and other financial instruments with similar characteristics including inverse floating rate securities. During the six months ended September 30, 2006, Select Tax-Free 2 (NXQ) and Select Tax-Free 3 (NXR) invested in inverse floating rate securities for the purpose of enhancing portfolio yield. Inverse floating rate securities are identified in the Portfolio of Investments and are valued daily. The interest rate of an inverse floating rate security has an inverse relationship to the interest rate of a short-term floating rate security. Consequently, as the interest rate of the floating rate security rises, the interest rate on the inverse floating rate security declines. Conversely, as the interest rate of the floating rate security declines, the interest rate on the inverse floating rate security rises. The price of an inverse floating rate security will be more volatile than that of an otherwise comparable fixed rate security since the interest rate is dependent on the interest rate on the fixed rate bonds that underly the inverse floater or the general level of long-term interest rates as well as the short-term interest paid on the floating rate security, and because the inverse floating rate security typically bears the risk of loss of a greater face value of such underlying bond. Select Tax-Free (NXP), California Select Tax-Free (NXC) and New York Select Tax-Free (NXN) did not invest in any such instruments during the six months ended September 30, 2006. Custodian Fee Credit Each Fund has an arrangement with the custodian bank whereby certain custodian fees and expenses are reduced by credits earned on each Fund's cash on deposit with the bank. Such deposit arrangements are an alternative to overnight investments. Indemnifications Under the Funds' organizational documents, their Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Funds enter into contracts that provide general indemnifications to other parties. The Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Funds that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote. 51 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) 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 None of the Funds engaged in transactions of their own shares during the six months ended September 30, 2006, nor during the fiscal year ended March 31, 2006. 3. INVESTMENT TRANSACTIONS Purchases and sales of investments (including maturities but excluding short-term investments) during the six months ended September 30, 2006, were as follows: CALIFORNIA NEW YORK SELECT SELECT SELECT SELECT SELECT TAX-FREE TAX-FREE 2 TAX-FREE 3 TAX-FREE TAX-FREE (NXP) (NXQ) (NXR) (NXC) (NXN) --------------------------------------------------------------------------------------------------------- Purchases $3,505,334 $8,192,262 $19,162,832 $9,782,701 $1,690,648 Sales and maturities 2,704,683 5,386,161 16,413,265 9,222,770 1,132,404 ========================================================================================================= 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 Funds.

MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES Each Fund's management fee is separated into two components - a complex-level component, based on the aggregate amount of all fund assets managed by Nuveen Asset Management (the "Adviser"), a wholly owned subsidiary of Nuveen Investments, Inc., ("Nuveen"), and a specific fund-level component, based only on the amount of assets within each individual fund. This pricing structure enables Nuveen fund shareholders to benefit from growth in the assets within each individual fund as well as from growth in the amount of complex-wide assets managed by the Adviser. The annual fund-level fee, payable monthly, for each Fund is based upon the average daily net assets of each Fund as follows: SELECT TAX-FREE 2 (NXQ) SELECT TAX-FREE 3 (NXR) CALIFORNIA SELECT TAX-FREE (NXC) SELECT TAX-FREE (NXP) NEW YORK SELECT TAX-FREE (NXN) AVERAGE DAILY NET ASSETS FUND-LEVEL FEE RATE FUND-LEVEL FEE RATE -------------------------------------------------------------------------------------------- For the first $125 million .0500% .1000% For the next $125 million .0375 .0875 For the next $250 million .0250 .0750 For the next $500 million .0125 .0625 ============================================================================================ 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 September 30, 2006, the complex-level fee rate was .1857%. 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. 54 The management fee compensates the Adviser for overall investment advisory and administrative services and general office facilities. The Funds pay no compensation directly to those of its Trustees who are affiliated with the Adviser or to its Officers, all of whom receive remuneration for their services to the Funds from the Adviser or its affiliates. The Board of 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. At this time, management is evaluating 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 Funds. Financial Accounting Standards Board Statement on Financial Accounting Standards No. 157 In September 2006, the Financial Accounting Standards Board (FASB) issued Statement on 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 September 30, 2006, the Funds do 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. 55 Notes to FINANCIAL STATEMENTS (Unaudited) (continued) 7.

(a) For the six months ended September 30, 2006. 58-59 spread ANNUAL INVESTMENT MANAGEMENT AGREEMENT APPROVAL PROCESS The Board of Trustees is responsible for overseeing the performance of the investment adviser to the Funds and determining whether to continue the advisory arrangements. At a meeting held on May 23-25, 2006 (the "May Meeting"), the Board of Trustees of the Funds, including the independent Trustees, unanimously approved the continuance of the Investment Management Agreement between each Fund and NAM (the "Fund Adviser"). THE APPROVAL PROCESS During the course of the year, the Board received a wide variety of materials relating to the services provided by the Fund Adviser and the performance of each Fund. To assist the Board in its evaluation of the advisory contract with the Fund Adviser at the May Meeting, the independent Trustees received extensive materials in advance of their meeting which outlined, among other things: o the nature, extent and quality of services provided by the Fund Adviser; o the organization and business operations of the Fund Adviser, including the responsibilities of various departments and key personnel; o the Fund's past performance, the Fund's performance compared to funds of similar investment objectives compiled by an independent third party and to customized benchmarks; o the profitability of the Fund Adviser and certain industry profitability analyses for unaffiliated advisers; o the expenses of the Fund Adviser in providing the various services; o the advisory fees (gross and net management fees) and total expense ratios of the Fund, including comparisons of such fees and expenses with those of comparable, unaffiliated funds based on information and data provided by Lipper (the "Peer Universe") as well as compared to a subset of funds within the Peer Universe (the "Peer Group") to the respective Fund (as applicable); o the advisory fees the Fund Adviser assesses to other types of investment products or clients; o the soft dollar practices of the Fund Adviser, if any; and o from independent legal counsel, a legal memorandum describing, among other things, the duties of the Trustees under the Investment Company Act of 1940 (the "1940 Act") as well as the general principles of relevant state law in reviewing and approving advisory contracts; the requirements of the 1940 Act in such matters; an adviser's fiduciary duty with respect to advisory agreements and compensation; the standards used by courts in determining whether investment company boards of directors have fulfilled their duties; and factors to be considered by the Board in voting on advisory agreements. At the May Meeting, the Fund Adviser made a presentation to and responded to questions from the Board. After the presentations and after reviewing the written materials, the independent Trustees met privately with their legal counsel to review the Board's duties in reviewing advisory contracts and consider the renewal of the advisory contracts. It is with this background that the Trustees considered the advisory contract with the Fund Adviser. The independent Trustees, in consultation with independent counsel, reviewed the factors set out in judicial decisions and SEC directives relating to the renewal of advisory contracts. As outlined in more detail below, the Trustees considered all factors they believed relevant with respect to each Fund, including the following: (a) the nature, extent and quality of the services to be provided by the Fund Adviser; (b) the investment performance of the Fund and the Fund Adviser; (c) the costs of the services to be provided and profitability of the Fund Adviser and its affiliates; (d) the extent to which economies of scale would be realized as the Fund grows; and (e) whether fee levels reflect these economies of scale for the benefit of Fund investors. A. NATURE, EXTENT AND QUALITY OF SERVICES In reviewing the Fund Adviser, the Trustees considered the nature, extent and quality of the Fund Adviser's services. The Trustees reviewed materials outlining, among other things, the Fund Adviser's organization and business; the types of services that the Fund Adviser or its affiliates provide and are expected to provide to the Funds; the performance record of the applicable Fund (as described in further detail below); and any initiatives and enhancements Nuveen has taken for its municipal fund product line. In connection with their continued service as Trustees, the Trustees also have a good understanding of the Fund Adviser's organization, operations and personnel. In this regard, the Trustees are familiar with and have evaluated the professional experience, qualifications and credentials of the Fund Adviser's personnel. The Trustees further reviewed materials describing, among other things, the teams and personnel 60 involved in the investment, research, risk-management and operational processes involved in managing municipal funds and their respective functions. Given the Trustees' experience with the Funds and Fund Adviser, the Trustees recognized the demonstrated history of care and depth of experience of the respective personnel in managing these Funds. In this regard, the Trustees considered the continued quality of the Fund Adviser's investment process in making portfolio management decisions as well as additional refinements and improvements adopted to the portfolio management processes noted below. With respect to the services provided to municipal funds, including the Funds, the Trustees noted that the Fund Adviser continues to make refinements to its portfolio management process including, among other things, the increased use of derivatives to enhance management of risk, additional analytical software for research staff and improved municipal pricing processes. In addition to advisory services, the independent Trustees considered the quality of any administrative or non-advisory services provided. The Fund Adviser provides the Funds with such administrative and other services (exclusive of, and in addition to, any such services provided by others for the Funds) and officers and other personnel as are necessary for the operations of the respective Fund. In connection with the review of the Investment Management Agreement, the Trustees considered the extent and quality of these other services which include, among other things, providing: product management (e.g., product positioning, performance benchmarking, risk management); fund administration (e.g., daily net asset value pricing and reconciliation, tax reporting, fulfilling regulatory filing requirements); oversight of third party service providers; administration of board relations (e.g., organizing board meetings and preparing related materials); compliance (e.g., monitoring compliance with investment policies and guidelines and regulatory requirements); and legal support (e.g., helping prepare and file registration statements, amendments thereto, proxy statements and responding to regulatory requests and/or inquiries). As the Funds operate in a highly regulated industry and given the importance of compliance, the Trustees considered, in particular, the additions of experienced personnel to the compliance teams and the enhancements to technology and related systems to support the compliance activities for the Funds (including a new reporting system for quarterly portfolio holdings). In addition to the foregoing, the Trustees also noted the additional services that the Fund Adviser or its affiliates provide to closed-end funds, including, in particular, secondary market support activities. The Trustees recognized Nuveen's continued commitment to supporting the secondary market for the common shares of its closed-end funds through a variety of initiatives designed to raise investor and analyst awareness and understanding of closed-end funds. These efforts include providing advertising and other media relations programs, continued contact with analysts, maintaining and enhancing its website for closed-end funds, and targeted advisor communication programs. With respect to funds that utilize leverage through the issuance of preferred shares, the Trustees noted Nuveen's continued support for the preferred shares by maintaining, among other things, an in-house preferred trading desk; designating a product manager whose responsibilities include creating and disseminating product information and managing relations in connection with the preferred share auction; and maintaining systems necessary to test compliance with rating agency requirements. Based on their review, the Trustees found that, overall, the nature, extent and quality of services provided (and expected to be provided) to the respective Funds under the Investment Management Agreement were of a high level and were satisfactory. B. THE INVESTMENT PERFORMANCE OF THE FUND AND FUND ADVISER The Board considered the investment performance for each Fund, including the Fund's historic performance as well as its performance compared to funds with similar investment objectives identified by an independent third party (the "Performance Peer Group") and portfolio level performance against customized benchmarks, as described below. In evaluating the performance information, in certain instances, the Trustees noted that the closest Performance Peer Group for a Fund still may not adequately reflect such Fund's investment objectives, strategies and portfolio duration, thereby limiting the usefulness of the comparisons of such Fund's performance with that of the Performance Peer Group. With respect to state specific municipal funds, the Trustees recognized that certain state municipal funds do not have a corresponding state specific Performance Peer Group in which case their performance is measured against a more general municipal category for various states. The closed-end state municipal funds that do not have corresponding state-specific Performance Peer Groups are from Arizona, Connecticut, Georgia, Maryland, Massachusetts, Missouri, North Carolina, Ohio, Texas, and Virginia. Further, due to a lack of state-specific unleveraged categories, certain unleveraged state municipal funds are included in their leveraged state category (such as, the Nuveen California Select Tax-Free Income Fund, Nuveen California Municipal Value Fund, Nuveen New York Select Tax-Free Income Fund and Nuveen New York Municipal Value Fund). In reviewing performance, the Trustees reviewed performance information including, among other things, total return information compared with the Fund's Performance Peer Group for the one-, three- and five-year periods (as applicable) ending December 31, 2005. The Trustees also reviewed the Fund's portfolio level performance (which does not reflect fund level fees and expenses) compared to customized portfolio-level benchmarks for the one- and three-year periods ending December 31, 2005 (as applicable). This analysis is designed to assess the efficacy of investment decisions against appropriate measures of risk and total return, within specific market segments. This information supplements the Fund performance information provided to the Board at each of their quarterly meetings. Based on their review, the Trustees determined that the respective Fund's absolute and relative investment performance over time had been satisfactory. C. FEES, EXPENSES AND PROFITABILITY 1. FEES AND EXPENSES In evaluating the management fees and expenses of a Fund, the Board reviewed, among other things, the Fund's advisory fees (net and gross management fees) and total expense ratios (before and after expense reimbursements and/or waivers) in absolute terms as well as comparisons to the gross management fees (before waivers), net management fees (after waivers) and total expense ratios (before and after waivers) of comparable funds in the Peer Universe and the Peer Group. The Trustees reviewed data regarding the construction of Peer Groups as well as the methods of measurement for the fee and expense analysis and the performance analysis. In certain cases, due to the small number of peers in the Peer Universe, the Peer Universe and Peer Group may be the same. Further, the Trustees recognized that in certain cases the closest Peer Universe and/or Peer Group did not 61 ANNUAL INVESTMENT MANAGEMENT AGREEMENT APPROVAL PROCESS (continued) adequately reflect the Fund's investment objectives and strategies limiting the usefulness of comparisons. In reviewing comparisons, the Trustees also considered the size of the Peer Universe and/or Peer Group, the composition of the Peer Group (including differences in the use of leverage and insurance) as well as differing levels of fee waivers and/or expense reimbursements. In this regard, the Trustees considered the fund-level and complex-wide breakpoint schedules (described in further detail below) and any fee waivers and reimbursements provided by Nuveen (applicable, in particular, for certain funds launched since 1999). Based on their review of the fee and expense information provided, the Trustees determined that each Fund's net total expense ratio was within an acceptable range compared to peers. 2. COMPARISONS WITH THE FEES OF OTHER CLIENTS The Trustees further reviewed data comparing the advisory fees of the Fund Adviser with fees the Fund Adviser charges to other clients, including municipal managed accounts. In general, the fees charged for separate accounts are somewhat lower than the fees assessed to the Funds. The Trustees recognized that the differences in fees are attributable to a variety of factors, including the differences in services provided, product distribution, portfolio investment policies, investor profiles, account sizes and regulatory requirements. The Trustees noted, in particular, that the range of services provided to the Funds is more extensive than that provided to managed separate accounts. As described in further detail above, such additional services include, but are not limited to, providing: product management, fund administration, oversight of third party service providers, administration of board relations, and legal support. Funds further operate in a highly regulated industry requiring extensive compliance functions compared to the other investment products. In addition to the costs of the additional services, administrative costs may also be greater for funds as the average account size for separate accounts is notably larger than the retail accounts of funds. Given the differences in the product structures, particularly the extensive services provided to closed-end municipal funds, the Trustees believe such facts justify the different levels of fees. 3. PROFITABILITY OF FUND ADVISER In conjunction with its review of fees, the Trustees also considered the profitability of Nuveen Investments for advisory activities (which incorporated Nuveen's wholly-owned affiliated sub-advisers). The Trustees reviewed data comparing Nuveen's profitability with other fund sponsors prepared by three independent third party service providers as well as comparisons of the revenues, expenses and profits margins of various unaffiliated management firms with similar amounts of assets under management prepared by Nuveen. The Trustees further reviewed the 2005 Annual Report for Nuveen Investments. In considering profitability, the Trustees recognized the inherent limitations in determining profitability as well as the difficulties in comparing the profitability of other unaffiliated advisers. Profitability may be affected by numerous factors, including the methodology for allocating expenses, the adviser's business mix, the types of funds managed, the adviser's capital structure and cost of capital. Further, individual fund or product line profitability of other sponsors is generally not publicly available. Accordingly, the profitability information that is publicly available from various investment advisory or management firms may not be representative of the industry. Notwithstanding the foregoing, in reviewing profitability, the Trustees reviewed Nuveen's methodology and assumptions for allocating expenses across product lines to determine profitability. In this regard, the methods of allocation used appeared reasonable. The Trustees also, to the extent available, compared Nuveen's profitability margins (including pre- and post-marketing profit margins) with the profitability of various unaffiliated management firms. The Trustees noted that Nuveen's profitability is enhanced due to its efficient internal business model. The Trustees also recognized that while a number of factors affect profitability, Nuveen's profitability may change as fee waivers and/or expense reimbursement commitments of Nuveen to various funds in the Nuveen complex expire. To keep apprised of profitability and developments that may affect profitability, the Trustees have requested profitability analysis be provided periodically during the year. Based on their review, the Trustees were satisfied that the Fund Adviser's level of profitability was reasonable in light of the services provided. In evaluating the reasonableness of the compensation, the Trustees also considered any other revenues paid to the Fund Adviser as well as any indirect benefits (such as soft dollar arrangements, if any) the Fund Adviser and its affiliates are expected to receive that are directly attributable to their management of the Funds, if any. See Section E below for additional information. Based on their review of the overall fee arrangements of the applicable Fund, the Trustees determined that the advisory fees and expenses of the respective Fund were reasonable. 62 D. ECONOMIES OF SCALE AND WHETHER FEE LEVELS REFLECT THESE ECONOMIES OF SCALE With respect to economies of scale, the Trustees recognized the potential benefits resulting from the costs of a fund being spread over a larger asset base as a fund grows. To help ensure the shareholders share in these benefits, the Trustees have reviewed and considered the breakpoints in the advisory fee schedules that reduce advisory fees as the applicable Fund's assets grow. In addition to advisory fee breakpoints as assets in a respective Fund rise, after lengthy discussions with management, the Board also approved a complex-wide fee arrangement that was introduced on August 1, 2004. Pursuant to the complex-wide fee arrangement, the fees of the funds in the Nuveen complex, including the Funds, are reduced as the assets in the fund complex reach certain levels. In evaluating the complex-wide fee arrangement, the Trustees considered, among other things, the historic and expected fee savings to shareholders as assets grow, the amount of fee reductions at various asset levels, and that the arrangement would extend to all funds in the Nuveen complex. The Trustees noted that 2005 was the first full year to reflect the fee reductions from the complex wide fee arrangement. The Trustees also considered the impact, if any, the complex-wide fee arrangement may have on the level of services provided. Based on their review, the Trustees concluded that the breakpoint schedule and complex-wide fee arrangement currently was acceptable and desirable in providing benefits from economies of scale to shareholders. E. INDIRECT BENEFITS In evaluating fees, the Trustees also considered any indirect benefits or profits the Fund Adviser or its affiliates may receive as a result of its relationship with each Fund. In this regard, the Trustees considered revenues received by affiliates of the Fund Adviser for serving as agent at Nuveen's preferred trading desk and for serving as a co-manager in the initial public offering of new closed-end exchange traded funds. In addition to the above, the Trustees considered whether the Fund Adviser received any benefits from soft dollar arrangements. With respect to NAM, the Trustees noted that NAM does not currently have any soft dollar arrangements and does not pay excess brokerage commissions (or spreads on principal transactions) in order to receive research services; however, the Fund Adviser may from time to time receive and have access to research generally provided to institutional clients. The Trustees did not identify any single factor discussed previously as all-important or controlling. The Trustees, including a majority of independent Trustees, concluded that the terms of the Investment Management Agreements were fair and reasonable, that the Fund Adviser's fees are reasonable in light of the services provided to each Fund, and that the renewal of the Investment Management Agreements should be approved 63 Reinvest Automatically EASILY AND CONVENIENTLY Sidebar text: NUVEEN MAKES REINVESTING EASY. A PHONE CALL IS ALL IT TAKES TO SET UP YOUR REINVESTMENT ACCOUNT. NUVEEN CLOSED-END FUNDS DIVIDEND REINVESTMENT PLAN Your Nuveen Closed-End Fund allows you to conveniently reinvest dividends and/or capital gains distributions in additional fund shares. By choosing to reinvest, you'll be able to invest money regularly and automatically, and watch your investment grow through the power of tax-free compounding. Just like dividends or distributions in cash, there may be times when income or capital gains taxes may be payable on dividends or distributions that are reinvested. It is important to note that an automatic reinvestment plan does not ensure a profit, nor does it protect you against loss in a declining market. EASY AND CONVENIENT To make recordkeeping easy and convenient, each month you'll receive a statement showing your total dividends and distributions, the date of investment, the shares acquired and the price per share, and the total number of shares you own. HOW SHARES ARE PURCHASED The shares you acquire by reinvesting will either be purchased on the open market or newly issued by the Fund. If the shares are trading at or above net asset value at the time of valuation, the Fund will issue new shares at the 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.

THESE CHANGES ARE INTENDED TO ENABLE PLAN PARTICIPANTS UNDER CERTAIN CIRCUMSTANCES TO REINVEST FUND DISTRIBUTIONS AT A LOWER AGGREGATE COST THAN IS POSSIBLE UNDER THE EXISTING PLAN. Shareholders who do not wish to continue as participants under the amended Plan may withdraw from the Plan by notifying the Plan Agent prior to the effective date of the amendments. Participants should refer to their Plan document for notification instructions, or may simply call Nuveen at (800) 257-8787. Fund shareholders who elect to participate in the Plan are able to have Fund distributions consisting of income dividends, realized capital gains and returns of capital automatically reinvested in additional Fund shares. Under the Plan's existing terms, the Plan Agent purchases Fund shares in the open market if the Fund's shares are trading at a discount to their net asset value on the payable date for the distribution. If the Fund's shares are trading at or above their net asset value on the payable date for the distribution, the Plan Agent purchases newly-issued Fund shares directly from the Fund at a price equal to the greater of the shares' net asset value or 95% of the shares' market value. Under the Plan's amended terms, 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. This change will permit Plan participants under these circumstances to reinvest Fund distributions at a lower aggregate cost than is possible under the existing Plan. 65 Notes 66 Other Useful INFORMATION QUARTERLY PORTFOLIO OF INVESTMENTS AND PROXY VOTING INFORMATION Each Fund's (i) quarterly portfolio of investments, (ii) information regarding how the Funds 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 Funds 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.

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. BOARD OF TRUSTEES Robert P.
