Portfolio management review

Delaware Investments® Closed-End Municipal Bond Funds
April 9, 2013

Municipal bond market conditions

During the Funds’ fiscal year ended March 31, 2013, the U.S. tax-exempt bond market, as measured by the Barclays Municipal Bond Index, returned 5.25%. In this favorable environment, higher yielding, lower-rated municipal bonds fared the best overall, with below-investment-grade issues gaining 14.23%, compared to returns of 6.50% and 3.78% generated by the higher-rated BBB and AAA segments of the market, respectively. (Data: Barclays.)

On Jan. 1, 2013, an agreement was reached in Washington, D.C., known as the American Taxpayer Relief Act of 2012. The good news for the municipal market was that the deal did not include a 28% cap on the municipal tax exemption.

Fund positioning: maintaining a long-standing approach

Our portfolio management strategy remained consistent throughout the Funds’ fiscal year. We continued investing by utilizing a bottom-up approach to portfolio construction, meaning that we evaluated investment opportunities individually based on thorough research; ultimately, we selected bonds that we believed offered a favorable balance between risk and potential reward.

We were also mindful of market shifts that could lead to new opportunities (or risks) for investors. Several such situations occurred during the fiscal year, as risks emerged that we believed justified making the portfolio slightly more defensive.

One of these shifts took place in the final months of the fiscal year. Especially in light of back-to-back years of strong performance in the municipal bond market, we thought it prudent to take a defensive position in an effort to seek to mitigate some of the risk to the Funds from a potential rise in long-term interest rates. This entailed modestly reducing the Funds’ exposure to longer-maturity securities. In addition, given global macroeconomic challenges, we limited the Funds’ allocations to certain lower-rated bonds that we believed were potentially at risk. We should note that this shift represented only subtle changes to the Funds’ portfolios. Throughout the Funds’ fiscal year, we maintained our usual focus on seeking to generate relative outperformance by emphasizing bonds within the lower tiers of the investment-grade credit ratings.

This is a segment of the market in which we believe our credit research capabilities have the potential to add value to the overall investment process.

Performance effects

Although we slightly reduced the Funds’ exposure to lower rated credit and decreased positions in bonds with longer maturities, these credits were among the strongest-performing bonds within the Funds. Additionally, the typically maintained overweight positions in these securities during the fiscal year.

Within Delaware Investments Colorado Municipal Income Fund, Inc., the strongest performing bonds tended to include issues within the healthcare sector (one example was issued by the Colorado Health Facilities Authority, with a coupon of 5% and a maturity date of 2040). The weaker performers, meanwhile, included an issue by the Puerto Rico Infrastructure Financing Authority, which felt much pressure among that commonwealth’s pension-related challenges and uncertainty surrounding a newly elected governor.

Within Delaware Investments Minnesota Municipal Income Fund, II Inc., notable performers included bonds issued by the Dakota and Washington Counties Housing and Redevelopment Authority. These bonds were issued with a 8.375% coupon, and are scheduled to mature in 2021. Other contributors included tobacco settlement bonds, with an S&P rating of A- and a maturity date of 2031. The positive effects generated by these bonds were offset somewhat by the underperformance of bonds such as those issued by the Laurentian Energy Authority, with a 5.0% coupon and a maturity of 2021. Puerto Rican bonds likewise posed a mild drag on the Fund’s performance, including bonds issued by the Puerto Rico Electric Power Authority.

Delaware Investments National Municipal Income Fund experienced a positive contribution from so-called tobacco settlement bonds. Another notable contributor to the Fund’s performance was a bond issued by the West Virginia Hospital Finance Authority, with a stated coupon of 9.125% and a maturity date of 2041. Bonds issued out of Puerto Rico, including an issue by the Puerto Rico Sales Tax Financing Corporation, were the weakest performers across the Fund.

1 Total investment return is calculated assuming a purchase of common stock on the opening of the first day and a sale on the closing of the last day of each period reported. Dividends and distributions, if any, are assumed for the purposes of this calculation to be reinvested at prices obtained under the Fund’s dividend reinvestment plan. Generally, total investment return based on net asset value will be higher than total investment return based on market value in periods where there is an increase in the discount or a decrease in the premium of the market value to the net asset value from the beginning to the end of such periods. Conversely, total investment return based on net asset value will be lower than total investment return based on market value in periods where there is a decrease in the discount or an increase in the premium of the market value to the net asset value from the beginning to the end of such periods.
2 Ratios do not reflect the effect of dividend payments to preferred shareholders, if applicable.
3 Ratio reflects total net investment income less dividends paid to preferred shareholders, if applicable, divided by average net assets applicable to common shareholders.
4 In November 2011, the Fund issued a new series of 300 variable rate preferred shares, with a liquidation preference of $100,000 per share.
5 Excluding any accumulated but unpaid dividends.

Delaware Investments® Closed-End Municipal Bond Funds
March 31, 2013

Delaware Investments Colorado Municipal Income Fund, Inc. (Colorado Municipal Fund) and Delaware Investments Minnesota Municipal Income Fund II, Inc. (Minnesota Municipal Fund II) are organized as Minnesota corporations and Delaware Investments National Municipal Income Fund (National Municipal Fund) is organized as a Massachusetts business trust (each referred to as a Fund and collectively as the Funds). Colorado Municipal Fund, Minnesota Municipal Fund II and National Municipal Fund are considered diversified closed-end management investment companies under the Investment Company Act of 1940, as amended. The Funds’ shares trade on the New York Stock Exchange MKT, the successor to the American Stock Exchange.

The investment objective of each of the Colorado Municipal Fund and Minnesota Municipal Fund II is to provide current income exempt from federal income tax and from state personal income tax, if any, consistent with the preservation of capital. The investment objective of the National Municipal Fund is to provide current income exempt from federal income tax, consistent with the preservation of capital. Each of Colorado Municipal Fund and Minnesota Municipal Fund II seek to achieve its investment objective by investing substantially all of its net assets in investment grade, tax-exempt municipal obligations of its respective state at the time of investment. The National Municipal Fund seeks to achieve its investment objective by investing at least 80% of its net assets in securities the income from which is exempt from federal income tax.

1. Significant Accounting Policies

The following accounting policies are in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and are consistently followed by the Funds.

Security Valuation — Debt securities are valued based upon valuations provided by an independent pricing service or broker and reviewed by management. To the extent current market prices are not available, the pricing service may take into account developments related to the specific security, as well as transactions in comparable securities. Valuations for fixed income securities utilize matrix systems, which reflect such factors as security prices, yields, maturities, and ratings, and are supplemented by dealer and exchange quotations. Generally, other securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith under the direction of each Fund’s Board of Directors/Trustees (each a Board, and collectively, the Boards). In determining whether market quotations are readily available or fair valuation will be used, various factors will be taken into consideration, such as market closures or suspension of trading in a security.

Federal Income Taxes — No provision for federal income taxes has been made as each Fund intends to continue to qualify for federal income tax purposes as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and make the requisite distributions to shareholders. The Funds evaluate tax positions taken or expected to be taken in the course of preparing the Funds’ 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 are recorded as a tax benefit or expense in the current year. Management has analyzed the Funds’ tax positions taken for all open federal income tax years (March 31, 2010–March 31, 2013), and has concluded that no provision for federal income tax is required in the Funds’ financial statements.

Interest and Related Expenses — Interest and related expenses include, but are not limited to, interest expense, remarketing fees, liquidity fees, and trustees’ fees from the Funds’ participation in inverse floater programs where a Fund has transferred its own bonds to a trust that issues floating rate securities with an aggregate principal amount equal to the principal of the transferred bonds. In conveyance of the bond, the Funds receive the inverse floating rate securities and cash from the trust. As a result of certain rights retained by the Funds, the transfer of the bond is not considered a sale, but rather a form of financing for accounting purposes whereby the cash received is recorded as a liability and interest expense is recorded based on the interest rate of the floating rate securities. Remarketing fees, liquidity fees, and trustees’ expenses are recorded on the accrual basis. There were no interest and related expenses for the year ended March 31, 2013.

Use of Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the fair value of investments, the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates and the differences could be material.

Other — Expenses directly attributable to a Fund are charged directly to that Fund. Other expenses common to various funds within the Delaware Investments® Family of Funds are generally allocated amongst such funds on the basis of average net assets. Management fees and some other expenses are paid monthly. Security transactions are recorded on the date the securities are purchased or sold (trade date) for financial reporting purposes. Costs used in calculating realized gains and losses on the sale of investment securities are those of the specific securities sold. Interest income is recorded on the accrual basis. Discounts and premiums on debt securities are amortized to interest income over the lives of the respective securities using the effective interest method. Each Fund declares and pays dividends from net investment income monthly and distributions from net realized gain on investments, if any, annually. Each Fund may distribute income dividends and capital gains more frequently, if necessary for tax purposes. Dividends and distributions, if any, are recorded on the ex-dividend date.

The Funds may receive earnings credits from their custodian when positive cash balances are maintained, which are used to offset custody fees. There were no earnings credits for the year ended March 31, 2013.

2. Investment Management, Administration Agreements and Other Transactions with Affiliates

In accordance with the terms of its respective investment management agreement, each Fund pays Delaware Management Company (DMC), a series of Delaware Management Business Trust and the investment manager, an annual fee of 0.40% which is calculated daily based on the adjusted average daily net assets of each Fund.

Delaware Service Company, Inc. (DSC), an affiliate of DMC, provides fund accounting and financial administration oversight services to the Funds. For these services, the Funds pay DSC fees based on the aggregate daily net assets of the Delaware Investments® Family of Funds at the following annual rate: 0.0050% of the first $30 billion; 0.0045% of the next $10 billion; 0.0040% of the next $10 billion; and 0.0025% of aggregate average daily net assets in excess of $50 billion. The fees payable to DSC under the service agreement described above are allocated among all Funds in the Delaware Investments Family of Funds on a relative net asset value basis. For the year ended March 31, 2013, the Funds were charged as follows:

      Colorado       Minnesota       National
Municipal Municipal Municipal
  Fund Fund II Fund
$5,114 $12,259 $4,740

*DMC, as part of its administrative services, pays operating expenses on behalf of each Fund and is reimbursed on a periodic basis. Expenses include items such as printing of shareholder reports, legal and tax services, registration fees and directors/trustees’ fees.

As provided in the investment management agreement, each Fund bears the cost of certain legal and tax services, including internal legal and tax services provided to each Fund by DMC and/or its affiliates’ employees.

U.S. GAAP defines fair value as the price that the Funds would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. A three level hierarchy for fair value measurements has been established based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the asset or liability developed based on the best information available under the circumstances. Each Fund’s investment in its entirety is assigned a level based upon the observability of the inputs which are significant to the overall valuation. The three level hierarchy of inputs is summarized below.

Level 1 –  inputs are quoted prices in active markets for identical investments (e.g., equity securities, open-end investment companies, futures contracts, exchange-traded options contracts)
 
Level 2 –

other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market-corroborated inputs) (e.g., debt securities, government securities, swap contracts, foreign currency exchange contracts, foreign securities utilizing international fair value pricing, broker-quoted securities, fair valued securities)

 
Level 3 –

inputs are significant unobservable inputs (including the Fund’s own assumptions used to determine the fair value of investments) (e.g., broker-quoted securities, fair valued securities)

Level 3 investments are valued using significant unobservable inputs. The Fund may also use an income-based valuation approach in which the anticipated future cash flows of the investment are discounted to calculate fair value. Discounts may also be applied due to the nature or duration of any restrictions on the disposition of the investments. Valuations may also be based upon current market prices of securities that are comparable in coupon, rating, maturity and industry. The derived value of a Level 3 investment may not represent the value which is received upon disposition and this could impact the results of operations.

The following table summarizes the valuation of each Fund’s investments by fair value hierarchy levels as of March 31, 2013:

Colorado Municipal Fund
Level 2
Municipal Bonds        $ 102,632,038        
Short-Term Investments 200,000
Total $ 102,832,038
 
Minnesota Municipal Fund II
Level 2
Municipal Bonds          $ 246,431,961         
 
National Municipal Fund
Level 2
Municipal Bonds        $ 97,477,533        

During the year ended March 31, 2013, there were no transfers between Level 1 investments, Level 2 investments or Level 3 investments that had a material impact to the Funds. The Funds’ policy is to recognize transfers between levels at the beginning of the reporting period.

4. Dividend and Distribution Information

Income and long-term capital gain distributions are determined in accordance with federal income tax regulations, which may differ from U.S. GAAP. Additionally, distributions from net short-term gains on sales of investment securities are treated as ordinary income for federal income tax purposes. The tax character of dividends and distributions paid during the years ended March 31, 2013 and 2012 was as follows:

      Colorado       Minnesota       National
Municipal Municipal Municipal
Fund Fund II Fund
Year Ended 3/31/13                  
Ordinary income $ 11,156 $ 345,149 $ 4,581
Tax-exempt income 3,337,599 7,938,433 2,757,769
Long-term capital gain 467,717 115,050
Total $ 3,816,472 $ 8,398,632 $ 2,762,350
 
Year Ended 3/31/12
Ordinary income $ 959 $ 533 $ 8,868
Tax-exempt income 2,804,559 6,672,353 2,286,347
Total $ 2,805,518 $ 6,672,886 $ 2,295,215

5. Components of Net Assets on a Tax Basis

As of March 31, 2013, the components of net assets on a tax basis were as follows:

      Colorado       Minnesota       National
Municipal Municipal Municipal
Fund Fund II Fund
Shares of beneficial interest    $ 66,918,121       $ 157,931,075       $ 60,617,476   
Undistributed tax-exempt income 833,522 1,833,037 826,334
Undistributed ordinary income 10,968 559,635
Undistributed long-term capital gains 69,612 947,605
Distributions payable (33,394 ) (83,486 ) (33,394 )
Capital loss carryforwards (407,888 )
Unrealized appreciation 6,549,809 14,441,354 6,873,549
Net assets $ 74,348,638 $ 175,629,220 $ 67,876,077

The differences between book basis and tax basis components of net assets are primarily attributable to tax treatment of market discount on debt instruments.

For financial reporting purposes, capital accounts are adjusted to reflect the tax character of permanent book/tax differences. Reclassifications are primarily due to tax treatment of market discount on debt instruments. Results of operations and net assets were not affected by these reclassifications. For the year ended March 31, 2013, the Funds recorded the following reclassifications.

      Colorado       Minnesota       National
Municipal Municipal Municipal
Fund Fund II Fund
Undistributed net investment income    $ (6,909 )       $ (28,541 )       $ (92,980 )   
Accumulated net realized gain (loss) 6,909 28,541 92,980

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. At March 31, 2013, the Funds utilized capital loss carryforwards as follows:

Colorado       Minnesota       National
Municipal Municipal Municipal
  Fund Fund Fund
$—   $257,166     $1,339,948

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. Capital loss carryforwards remaining at March 31, 2013 will expire as follows:

      Colorado       Minnesota       National
Municipal Municipal Municipal
Year of Expiration Fund Fund II Fund
2018 $— $—   $407,888  

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the Act) was enacted, which changed various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. Under the Act, the Funds will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital loss carryforwards will retain their character as either short-term or long-term capital losses rather than being considered all short-term as permitted under previous regulation.

6. Capital Stock

Pursuant to their articles of incorporation, Colorado Municipal Fund and Minnesota Municipal Fund II each have 200 million shares of $0.01 par value common shares authorized. National Municipal Fund has been authorized to issue an unlimited amount of $0.01 par value common shares. The Funds did not repurchase any shares under the Share Repurchase Program during the year ended March 31, 2013. Shares issuable under the Funds’ dividend reinvestment plan are purchased by the Funds’ transfer agent, Computershare Shareowner Services LLC (Computershare), in the open market.

On February 18, 2011, the National Municipal Fund’s Board approved a tender offer for shares of the Arizona Municipal Fund’s common stock. The tender offer authorized the National Municipal Fund to purchase for cash up to 18% of the then-outstanding shares of the Arizona Municipal Fund’s common stock after the reorganization (Common Stock) at a per share price equal to 99% of the net asset value per share of the Common Stock at the expiration of the tender offer.

In connection with the tender offer, the National Municipal Fund purchased 994,051 shares of capital stock at a total cost of approximately $13,240,759. The tender offer was oversubscribed and all tenders of shares were subject to pro-ration (at a ratio of approximately 0.58504231) in accordance with the terms of its tender offer.

On November 15, 2011, Delaware Investments Colorado Municipal Income Fund, Inc. (Colorado Municipal Fund) and Delaware Investments Minnesota Municipal Income Fund II, Inc. (Minnesota Municipal Fund II), issued $30,000,000 and $75,000,000, respectively, of Series 2016 Variable Rate MuniFund Term Preferred (VMTP) Shares, with $100,000 liquidation value per share in a privately negotiated offering. On March 15, 2012, Delaware Investments National Municipal Income Fund (National Municipal Fund) issued $30,000,000 Series 2017 VMTP Shares, with $100,000 liquidation value per share in a privately negotiated offering. Proceeds from the issuance of VMTP Shares, net of offering expenses, were invested in accordance with each fund’s investment objective. The VMTP Shares were offered to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933.

Colorado Municipal Fund and Minnesota Municipal Fund II are obligated to redeem their respective VMTP Shares on December 1, 2016, unless earlier redeemed or repurchased by the Fund. National Municipal Fund is obligated to redeem its VMTP Shares on April 1, 2017, unless earlier redeemed or repurchased by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances. The VMTP Shares may be redeemed at the option of a Fund, subject to payment of a premium until December 1, 2013 (with respect to Minnesota Municipal Fund II and Colorado Municipal Fund) and April 1, 2014 (with respect to National Municipal Fund), and at par thereafter. A Fund may be obligated to redeem certain of the VMTP Shares if the Fund fails to maintain certain asset coverage and leverage ratio requirements and such failures are not cured by the applicable cure date. The redemption price per share is equal to the sum of the liquidation value per share plus any accumulated but unpaid dividends. Dividends on the VMTP Shares are set weekly, subject to adjustments in certain circumstances. The weight average dividend rates for the year ended March 31, 2013 were as follows:

Colorado       Minnesota       National
Municipal Municipal Municipal
  Fund Fund II Fund
1.4% 1.4% 1.4%

The Funds use leverage because their managers believe that, over time, leveraging may provide opportunities for additional income and total return for common shareholders. However, the use of leverage also can expose common shareholders to additional volatility. For example, as the prices of securities held by a Fund decline, the negative impact of these valuation changes on common share net asset value and common shareholder total return is magnified by the use of leverage; accordingly, the use of structural leverage may hurt a Fund’s overall performance.

Leverage may also cause the Funds to incur certain costs. In the event that a Fund is unable to meet certain criteria (including, but not limited to, maintaining certain ratings with Fitch Ratings and Moody’s Investor Service, funding dividend payments or funding redemptions), that Fund will pay additional fees with respect to the leverage.

7. Fund Merger

On June 20, 2011, the National Municipal Fund acquired all of the assets of the Delaware Investments Arizona Municipal Fund, Inc. (Acquired Fund), a closed-end investment company, in exchange for the shares of the National Municipal Fund (Acquiring Fund) pursuant to a Plan and Agreement of Reorganization (Reorganization). The shareholders of the Acquired Fund received shares of the Acquiring Fund equal to the aggregate net asset value of their share in the Acquired Fund prior to the Reorganization, as shown in the following table:

      Acquiring       Acquired      
Fund Fund
Shares Shares Value
Common Stock   2,422,200     3,100,925     $40,715,147  

The Reorganization was treated as a non-taxable event and, accordingly, the Acquired Fund’s basis in securities acquired reflected historical cost basis as of the date of transfer. The net assets and net unrealized appreciation of the Acquired Fund as of the close of business on June 17, 2011, were as follows:

Net assets $ 40,715,147
Net unrealized appreciation 65,229

The net assets of the Acquiring Fund before the acquisition were $31,792,649. The net assets of the Acquiring Fund immediately following the acquisition were $72,507,796.

Assuming that the acquisition had been completed on April 1, 2011, the beginning of the Acquiring Fund’s reporting period, the Acquiring Fund’s pro forma results of operations for the year ended March 31, 2012, are as follows:

Net investment income $ 2,611,659
Net realized gain on investments 909,699
Change in unrealized appreciation 5,974,605
Net increase in net assets resulting from operations 9,477,059

Because the combined investment portfolios have been managed as a single integrated portfolio since the acquisition was completed, it is not practicable to separate the amounts of revenue and earnings of the Acquired Fund that have been included in the National Municipal Fund’s statement of operations since June 20, 2011.

8. Derivatives

U.S. GAAP requires disclosures that enable investors to understand: 1) how and why an entity uses derivatives; 2) how they are accounted for; and 3) how they affect an entity’s results of operations and financial position.

Inverse Floaters — Each Fund may participate in inverse floater programs where a Fund transfers its own bonds to a trust that issues floating rate securities and inverse floating rate securities (inverse floaters) with an aggregate principal amount equal to the principal of the transferred bonds. The inverse floaters received by the Funds are derivative tax-exempt obligations with floating or variable interest rates that move in the opposite direction of short-term interest rates, usually at an accelerated speed. Consequently, the market values of the inverse floaters will generally be more volatile than other tax-exempt investments. The Funds typically use inverse floaters to adjust the duration of their portfolio. Duration measures a portfolio’s sensitivity to changes in interest rates. By holding inverse floaters with a different duration than the underlying bonds that a Fund transferred to the trust, the Fund seeks to adjust its portfolio’s sensitivity to changes in interest rates. The Funds may also invest in inverse floaters to add additional income to the Funds or to adjust the Funds’ exposure to a specific segment of the yield curve. At March 31, 2013, and during the year then ended, the Funds held no investments in inverse floaters.

9. Credit and Market Risk

The Funds concentrate their investments in securities issued by municipalities. Because each of the Colorado Municipal Income Fund and the Minnesota Municipal Income Fund invest substantially all of its net assets in municipal obligations of its respective state at the time of investment, events in that state may have a significant impact on the performance and investments of the Colorado Municipal Income Fund and the Minnesota Municipal Income Fund. These events may include economic or political policy changes, tax base erosion, state constitutional limits on tax increases, budget deficits and other financial difficulties, changes in the credit ratings assigned to the state’s municipal issuers, the effects of natural or human-made disasters, or other economic, legislative or political or social issues. Any downgrade to the credit rating of the securities issued by the U.S. government may result in a downgrade of securities issued by the states or U.S. territories. The National Municipal Fund will be subject to these risks as well but to a lesser extent because it invests at least 80% of its net assets in securities, the income from which is exempt from federal income tax and is not limited to investing substantially all of its assets in municipal obligations of a single state.

28



Each Fund may invest a percentage of assets in obligations of governments of U.S. territories, commonwealths and possessions such as Puerto Rico, the Virgin Islands or Guam. To the extent a Fund invests in such obligations, that Fund may be adversely affected by local political and economic conditions and developments within these U.S. territories, commonwealths and possessions. Currently Puerto Rico is experiencing financial difficulties, causing ratings organizations to downgrade Puerto Rican general obligation bonds as well as a number of other bonds issued in Puerto Rico, which negatively affects the market values and marketability of many or all Puerto Rican municipal obligations. The Funds hold some of these securities, which may negatively impact the Funds’ performance. If the economic situation in Puerto Rico changes, the volatility, credit quality and performance of the Funds could be affected to the extent a Fund holds Puerto Rican securities.

Many municipalities insure repayment for their obligations. Although bond insurance may reduce the risk of loss due to default by an issuer, such bonds remain subject to the risk that market value may fluctuate for other reasons and there is no assurance that the insurance company will meet its obligations. A real or perceived decline in creditworthiness of a bond insurer can have an adverse impact on the value of insured bonds held in each Fund. At March 31, 2013, the percentages of each Fund’s net assets insured by insurers are listed below and these securities have been identified in the statements of net assets.

Colorado Municipal Fund 36 %
Minnesota Municipal Fund II 8 %
National Municipal Fund 7 %

The Funds invest a portion of their assets in high yield fixed income securities, which are securities rated BB or lower by Standard & Poor’s (S&P) and/or Ba or lower by Moody’s Investors Service, Inc. (Moody’s), or similarly rated by another nationally recognized statistical rating organization. Investments in these higher yielding securities are generally accompanied by a greater degree of credit risk than higher rated securities. Additionally, lower rated securities may be more susceptible to adverse economic and competitive industry conditions than investment grade securities.

The Funds may invest in advanced refunded bonds, escrow secured bonds or defeased bonds. Under current federal tax laws and regulations, state and local government borrowers are permitted to refinance outstanding bonds by issuing new bonds. The issuer refinances the outstanding debt to either reduce interest costs or to remove or alter restrictive covenants imposed by the bonds being refinanced. A refunding transaction where the municipal securities are being refunded within 90 days from the issuance of the refunding issue is known as a “current refunding.” “Advance refunded bonds” are bonds in which the refunded bond issue remains outstanding for more than 90 days following the issuance of the refunding issue. In an advance refunding, the issuer will use the proceeds of a new bond issue to purchase high grade interest bearing debt securities which are then deposited in an irrevocable escrow account held by an escrow agent to secure all future payments of principal and interest and bond premium of the advance refunded bond. Bonds are “escrowed to maturity” when the proceeds of the refunding issue are deposited in an escrow account for investment sufficient to pay all of the principal and interest on the original interest payment and maturity dates.

Bonds are considered “pre-refunded” when the refunding issue’s proceeds are escrowed only until a permitted call date or dates on the refunded issue with the refunded issue being redeemed at the time, including any required premium. Bonds become “defeased” when the rights and interests of the bondholders and of their lien on the pledged revenues or other security under the terms of the bond contract are substituted with an alternative source of revenues (the escrow securities) sufficient to meet payments of principal and interest to maturity or to the first call dates. Escrowed secured bonds will often receive a rating of AAA from Moody’s, S&P, and/or Fitch Ratings due to the strong credit quality of the escrow securities and the irrevocable nature of the escrow deposit agreement.

Certain obligations held by the Fund may have liquidity protection to ensure that the receipt of payments due on the underlying security is timely. Such protection may be provided through guarantees, insurance policies or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction or through a combination of such approaches. The Fund will not pay any additional fees for such credit support, although the existence of credit support may increase the price of a security.

Each Fund may invest up to 15% of its net assets in illiquid securities, which may include securities with contractual restrictions on resale, securities exempt from registration under Rule 144A of the Securities Act of 1933, as amended, and other securities which may not be readily marketable. The relative illiquidity of these securities may impair each Fund from disposing of them in a timely manner and at a fair price when it is necessary or desirable to do so. While maintaining oversight, each Fund’s Board has delegated to DMC the day-to-day functions of determining whether individual securities are liquid for purposes of each Fund’s limitation on investments in illiquid securities. Securities eligible for resale pursuant to Rule 144A, which are determined to be liquid, are not subject to the Funds’ 15% limit on investments in illiquid securities. As of March 31, 2013, no securities have been determined to be illiquid under the Funds’ Liquidity Procedures. Rule 144A securities have been identified on the statements of net assets.

10. Contractual Obligations

The Funds enter into contracts in the normal course of business that contain a variety of indemnifications. The Funds’ maximum exposure under these arrangements is unknown. However, the Funds have not had prior claims or losses pursuant to these contracts. Management has reviewed each Fund’s existing contracts and expects the risk of loss to be remote.

Notes to financial statements

Delaware Investments® Closed-End Municipal Bond Funds

11. National Municipal Income Fund — Investments in Municipal Securities Issued by Certain States

From time to time and consistent with its investment policies, the National Municipal Income Fund may invest a considerable portion of its assets in certain municipalities. As of the date of this report, the National Municipal Income Fund has invested 11.70% and 18.02% (each as a percentage of fixed income investments), respectively, in securities issued by the State of California and the State of New York, respectively. These investments could make the National Municipal Income Fund more sensitive to economic conditions in those states.

On May 23, 2011, shareholders of the National Municipal Fund and shareholders of the Delaware Investments Arizona Municipal Income Fund, Inc. (Arizona Muni Fund) approved the acquisition of substantially all of the assets of Arizona Muni Fund in exchange for newly issued common shares of the National Municipal Fund, which was structured as a tax-free transaction. This acquisition was completed after the close of business on June 17, 2011. As of March 31, 2013, municipal bonds issued by the State of Arizona constitute approximately 13% of the National Municipal Income Fund’s portfolio. These investments could make the National Municipal Fund more sensitive to economic conditions in Arizona than other more geographically diversified national municipal income funds.

12. Subsequent Events

Management has determined that no material events or transactions occurred subsequent to March 31, 2013 that would require recognition or disclosure in the Funds’ financial statements.

Report of independent
registered public accounting firm

To the Board of Directors/Trustees and the Shareholders of
Delaware Investments Colorado Municipal Income Fund, Inc.,
Delaware Investments Minnesota Municipal Income Fund II, Inc. and
Delaware Investments National Municipal Income Fund:

In our opinion, the accompanying statements of net assets, statements of assets and liabilities, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Delaware Investments Colorado Municipal Income Fund, Inc., Delaware Investments Minnesota Municipal Income Fund II, Inc. and Delaware Investments National Municipal Income Fund (hereafter referred to as the “Funds”) at March 31, 2013, the results of each of their operations for the year then ended, the changes in each of their net assets for each of the two years in the period then ended and the financial highlights for each of the three years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements 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 are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at March 31, 2013 by correspondence with the custodian, provide a reasonable basis for our opinion. The financial highlights for each of the two years in the period ended March 31, 2010 were audited by other independent accountants whose report dated May 19, 2010 expressed an unqualified opinion on those statements.

The independent fund trustees, in particular, are advocates for shareholder interests. Each trustee has served in that capacity since he or she was elected to or appointed to the Board of Trustees, and will continue to serve until his or her retirement or the election of a new trustee in his or her place.

Item 2. Code of Ethics

     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, regardless of whether these individuals are employed by the registrant or a third party. A copy of the registrant’s Code of Business Ethics has been posted on the Delaware Investments Internet Web site at www.delawareinvestments.com. Any amendments to the Code of Business Ethics, and information on any waiver from its provisions granted by the registrant, will also be posted on this Web site within five business days of such amendment or waiver and will remain on the Web site for at least 12 months.

Item 3. Audit Committee Financial Expert

     The registrant’s Board of Trustees/Directors has determined that certain members of the registrant’s Audit Committee are audit committee financial experts, as defined below. For purposes of this item, an “audit committee financial expert” is a person who has the following attributes:

     a. An understanding of generally accepted accounting principles and financial statements;

     b. The ability to assess the general application of such principles in connection with the accounting for estimates, accruals, and reserves;

     c. Experience preparing, auditing, analyzing, or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant’s financial statements, or experience actively supervising one or more persons engaged in such activities;

     d. An understanding of internal controls and procedures for financial reporting; and

     e. An understanding of audit committee functions.

An “audit committee financial expert” shall have acquired such attributes through:

     a. Education and experience as a principal financial officer, principal accounting officer, controller, public accountant, or auditor or experience in one or more positions that involve the performance of similar functions;

     b. Experience actively supervising a principal financial officer, principal accounting officer, controller, public accountant, auditor, or person performing similar functions;

     c. Experience overseeing or assessing the performance of companies or public accountants with respect to the preparation, auditing, or evaluation of financial statements; or

     d. Other relevant experience.

     The registrant’s Board of Trustees/Directors has also determined that each member of the registrant’s Audit Committee is independent. In order to be “independent” for purposes of this item, the Audit Committee member may not: (i) other than in his or her capacity as a member of the Board of Trustees/Directors or any committee thereof, accept directly or indirectly any consulting, advisory or other compensatory fee from the issuer; or (ii) be an “interested person” of the registrant as defined in Section 2(a)(19) of the Investment Company Act of 1940.

1The instructions to Form N-CSR require disclosure on the relevant experience of persons who qualify as audit committee financial experts based on “other relevant experience.” The Board of Trustees/Directors has determined that Mr. Bennett qualifies as an audit committee financial expert by virtue of: his education and Chartered Financial Analyst designation; his experience as a credit analyst, portfolio manager and the manager of other credit analysts and portfolio managers; and his prior service on the audit committees of public companies.

     (f) Not applicable.

     (h) In connection with its selection of the independent auditors, the registrant’s Audit Committee has considered the independent auditors’ provision of non-audit services to the registrant’s investment adviser and other service providers under common control with the adviser that were not required to be pre-approved pursuant to Rule 2-01(c)(7)(ii) of Regulation S-X. The Audit Committee has determined that the independent auditors’ provision of these services is compatible with maintaining the auditors’ independence.

Item 5. Audit Committee of Listed Registrants

     The registrant has a separately-designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934. The members of the registrant’s Audit Committee are Thomas L. Bennett, Joseph W. Chow, John A. Fry, Frances A. Sevilla-Sacasa and Janet L. Yeomans.



Item 6. Investments

     (a) Included as part of report to shareholders filed under Item 1 of this Form N-CSR.

     (b) Divestment of securities in accordance with Section 13(c) of the Investment Company Act of 1940.

     Not applicable.

Item 7. Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies

     The registrant has formally delegated to its investment adviser(s) (the “Adviser”) the responsibility for making all proxy voting decisions in relation to portfolio securities held by the registrant. If and when proxies need to be voted on behalf of the registrant, the Adviser will vote such proxies pursuant to its Proxy Voting Policies and Procedures (the “Procedures”). The Adviser has established a Proxy Voting Committee (the “Committee”) which is responsible for overseeing the Adviser’s proxy voting process for the registrant. One of the main responsibilities of the Committee is to review and approve the Procedures to ensure that the Procedures are designed to allow the Adviser to vote proxies in a manner consistent with the goal of voting in the best interests of the registrant.

     In order to facilitate the actual process of voting proxies, the Adviser has contracted with Institutional Shareholder Services (“ISS”), which is a subsidiary of MSCI Inc., to analyze proxy statements on behalf of the registrant and other Adviser clients and vote proxies generally in accordance with the Procedures. The Committee is responsible for overseeing ISS’s proxy voting activities. If a proxy has been voted for the registrant, ISS will create a record of the vote. By no later than August 31 of each year, information (if any) regarding how the registrant voted proxies relating to portfolio securities during the most recently disclosed 12-month period ended June 30 is available without charge (i) through the registrant’s website at www.delawareinvestments.com; and (ii) on the Commission’s website at www.sec.gov.

     The Procedures contain a general guideline that recommendations of company management on an issue (particularly routine issues) should be given a fair amount of weight in determining how proxy issues should be voted. However, the Adviser will normally vote against management’s position when it runs counter to its specific Proxy Voting Guidelines (the “Guidelines”), and the Adviser will also vote against management’s recommendation when it believes that such position is not in the best interests of the registrant.

     As stated above, the Procedures also list specific Guidelines on how to vote proxies on behalf of the registrant. Some examples of the Guidelines are as follows: (i) generally vote for shareholder proposals asking that a majority or more of directors be independent; (ii) generally vote against proposals to require a supermajority shareholder vote; (iii) votes on mergers and acquisitions should be considered on a case-by-case basis, determining whether the transaction enhances shareholder value; (iv) generally vote against proposals at companies with more than one class of common stock to increase the number of authorized shares of the class that has superior voting rights; (v) generally vote re-incorporation proposals on a case-by-case basis; (vi) votes with respect to equity-based compensation plans are generally determined on a case-by-case basis; and (vii) generally vote for proposals requesting reports on the level of greenhouse gas emissions from a company’s operations and products.



     Because the registrant has delegated proxy voting to the Adviser, the registrant is not expected to encounter any conflict of interest issues regarding proxy voting and therefore does not have procedures regarding this matter. However, the Adviser does have a section in its Procedures that addresses the possibility of conflicts of interest. Most proxies which the Adviser receives on behalf of the registrant are voted by ISS in accordance with the Procedures. Because almost all registrant proxies are voted by ISS pursuant to the pre-determined Procedures, it normally will not be necessary for the Adviser to make an actual determination of how to vote a particular proxy, thereby largely eliminating conflicts of interest for the Adviser during the proxy voting process. In the very limited instances where the Adviser is considering voting a proxy contrary to ISS’s recommendation, the Committee will first assess the issue to see if there is any possible conflict of interest involving the Adviser or affiliated persons of the Adviser. If a member of the Committee has actual knowledge of a conflict of interest, the Committee will normally use another independent third party to do additional research on the particular proxy issue in order to make a recommendation to the Committee on how to vote the proxy in the best interests of the registrant. The Committee will then review the proxy voting materials and recommendation provided by ISS and the independent third party to determine how to vote the issue in a manner which the Committee believes is consistent with the Procedures and in the best interests of the registrant.

DESCRIPTION OF MATERIAL CONFLICTS OF INTEREST
     
Individual portfolio managers may perform investment management services for other funds or accounts similar to those provided to the Funds and the investment action for such other fund or account and the Funds may differ. For example, an account or fund may be selling a security, while another account or Fund may be purchasing or holding the same security. As a result, transactions executed for one fund or account may adversely affect the value of securities held by another fund, account or Fund. Additionally, the management of multiple other funds or accounts and the Funds may give rise to potential conflicts of interest, as a portfolio manager must allocate time and effort to multiple funds or accounts and the Funds. A portfolio manager may discover an investment opportunity that may be suitable for more than one account or fund. The investment opportunity may be limited, however, so that all funds or accounts for which the investment would be suitable may not be able to participate. The Manager has adopted procedures designed to allocate investments fairly across multiple funds or accounts.

     A portfolio manager’s management of personal accounts also may present certain conflicts of interest. While Delaware’s code of ethics is designed to address these potential conflicts, there is no guarantee that it will do so.

Compensation Structure
     
Each portfolio’s manager’s compensation consists of the following:

     Base Salary - Each named portfolio manager receives a fixed base salary. Salaries are determined by a comparison to industry data prepared by third parties to ensure that portfolio manager salaries are in line with salaries paid at peer investment advisory firms.

     Bonus - An objective component is added to the bonus for each manager that is reflective of account performance relative to an appropriate peer group or database. The following paragraph describes the structure of the non-guaranteed bonus.

     Each portfolio manager is eligible to receive an annual cash bonus, which is based on quantitative and qualitative factors. There is one pool for bonus payments for the fixed income department. The amount of the pool for bonus payments is determined by assets managed (including investment companies, insurance product-related accounts and other separate accounts), management fees and related expenses (including fund waiver expenses) for registered investment companies, pooled vehicles, and managed separate accounts. Generally, 60%-75% of the bonus is quantitatively determined. For more senior portfolio managers, a higher percentage of the bonus is quantitatively determined. For investment companies, each manager is compensated according the Fund’s Lipper or Morningstar peer group percentile ranking on a one-year, three-year, and five-year basis, with longer-term performance more heavily weighted. For managed separate accounts the portfolio managers are compensated according to the composite percentile ranking against the BNY Mellon, eVestment Alliance, and Callan Associates databases (or similar sources of relative performance data) on a one-year, three-year, and five-year basis, with longer term performance more heavily weighted. There is no objective award for a fund that falls below the 50th percentile, but incentives reach maximum potential at the 25th-30th percentile. There is a sliding scale for investment companies that are ranked above the 50th percentile. The remaining 25%-40% portion of the bonus is discretionary as determined by Delaware Investments and takes into account subjective factors.

     For new and recently transitioned portfolio managers, the compensation may be weighted more heavily towards a portfolio manager’s actual contribution and ability to influence performance, rather than longer-term performance. Management intends to move the compensation structure towards longer-term performance for these portfolio managers over time.



     Incentive Unit Plan - Portfolio managers may be awarded incentive unit awards (“Awards”) relating to the underlying shares of common stock of Delaware Management Holdings, Inc. issuable pursuant to the terms of the Delaware Investments Incentive Unit Plan (the “Plan”) adopted on November 30, 2010. Awards are no longer granted under the Delaware Investments U.S., Inc. 2009 Incentive Compensation Plan or the Amended and Restated Delaware Investments U.S., Inc. Incentive Compensation Plan, which was established in 2001.

     The Plan was adopted in order to: assist the Manager in attracting, retaining, and rewarding key employees of the company; enable such employees to acquire or increase an equity interest in the company in order to align the interest of such employees and the Manager; and provide such employees with incentives to expend their maximum efforts. Subject to the terms of the Plan and applicable award agreements, Awards typically vest in 25% increments on a four-year schedule, and shares of common stock underlying the Awards are issued after vesting. The fair market value of the shares of Delaware Management Holdings, Inc., is normally determined as of each March 31, June 30, September 30 and December 31 by an independent appraiser. Generally, a stockholder may put shares back to the company during the put period communicated in connection with the applicable valuation.

     Other Compensation - Portfolio managers may also participate in benefit plans and programs available generally to all employees.

Ownership of Securities
     
As of April 30, 2013, the portfolio managers did not own any shares of the Fund.
