²Total 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.

Notes to financial statements

Delaware Investments Closed-End Municipal Bond Funds
September 30, 2011 (Unaudited)

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 NYSE Amex Equities, the successor to the American Stock Exchange.

The investment objective of each Fund is to provide high current income exempt from federal income tax and from state personal income tax, if any, 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. 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. Short-term debt securities are valued at market value. 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 on federal income tax returns for all open tax years (March 31, 2008 – March 31, 2011), 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 six months ended September 30, 2011.

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 are amortized to interest income over the lives of the respective securities. 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 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 six months ended September 30, 2011.

The Funds may receive earnings credits from their transfer agent when positive cash balances are maintained, which are used to offset transfer agent fees. There were no earnings credits for the six months ended September 30, 2011.

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 six months ended September 30, 2011, the Funds were charged as follows:

Colorado	Minnesota	National
Municipal	Municipal	Municipal
Fund	Fund II	Fund
$1,664	$4,021	$1,358

At September 30, 2011, each Fund had liabilities payable to affiliates as follows:

	Colorado		Minnesota		National
	Municipal		Municipal		Municipal
	Fund		Fund II		Fund
Investment management fees payable to DMC		$22,598		$54,268		$24,280
Accounting administration and other expenses
payable to DSC		281		674		301
Other expenses payable to DMC and affiliates*		4,244		9,493		5,622

*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, fees for audit, 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. For the six months ended September 30, 2011, each Fund was charged for internal legal and tax services provided by DMC and/or its affiliates’ employees as follows:

Colorado	Minnesota	National
Municipal	Municipal	Municipal
Fund	Fund II	Fund
$17,624	$35,497	$9,441

Directors’/Trustees’ fees include expenses accrued by the Funds for each Director’s/Trustee’s retainer and meeting fees. Certain officers of DMC and DSC are officers and/or Directors/Trustees of the Trust. These officers and Directors/Trustees are paid no compensation by the Funds.

3. Investments

For the six months ended September 30, 2011, the Funds made purchases and sales of investment securities other than short-term investments as follows:

	Colorado		Minnesota		National
	Municipal		Municipal		Municipal
	Fund		Fund II		Fund
Purchases	$	10,300,514	$	5,110,792	$	16,889,597
Sales		11,504,835		4,499,638		25,525,341

At September 30, 2011, the cost of investments for federal income tax purposes has been estimated since final tax characteristics cannot be determined until fiscal year end. At September 30, 2011, the cost of investments and unrealized appreciation (depreciation) for each Fund were as follows:

	Colorado				Minnesota				National
	Municipal				Municipal				Municipal
	Fund				Fund II				Fund
Cost of investments		$	65,625,952			$	156,010,671			$	70,948,367
Aggregate unrealized appreciation		$	2,808,270			$	9,295,184			$	2,902,297

3. Investments (continued)

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, 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)

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)

The following table summarizes the valuation of each Fund’s investments by fair value hierarchy levels as of September 30, 2011:

	Colorado Municipal Fund
	Level 2
Municipal Bonds		$	66,798,819
Short-Term Investments			985,000
Total		$	67,783,819

	Minnesota Municipal Fund II
	Level 2
Municipal Bonds		$	164,138,949
Short-Term Investments			700,000
Total		$	164,838,949

	National Municipal Fund
	Level 2
Municipal Bonds		$	64,792,373
Short-Term Investments			8,700,000
Total		$	73,492,373

There were no unobservable inputs used to value investments at the beginning or end of the period.

During the six months ended September 30, 2011, there were no transfers between Level 1 investments, Level 2 investments or Level 3 investments that had a material impact to the Funds.

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 six months ended September 30, 2011 and the year ended March 31, 2011 was as follows:

	Colorado			Minnesota			National
	Municipal			Municipal			Municipal
	Fund			Fund II			Fund
Six Months Ended 9/30/11*

5. Components of Net Assets on a Tax Basis

The components of net assets are estimated since final tax characteristics cannot be determined until fiscal year end. As of September 30, 2011, the estimated 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			$	73,858,235
Undistributed tax-exempt income			353,483				1,036,687				312,039
Realized gains (losses) 4/1/11 – 9/30/11			136,455				(154,606	)			89,734
Capital loss carryforwards as of 3/31/11			(509,083	)			(1,959,315	)			(2,494,617	)
Unrealized appreciation of investments			2,157,867				8,828,278				2,543,992
Net assets		$	69,056,843			$	165,682,119			$	74,309,383

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 six months ended September 30, 2011, the Funds recorded an estimate of these differences since final tax characteristics cannot be determined until fiscal year end.

	Colorado				Minnesota				National
	Municipal				Municipal				Municipal
	Fund				Fund II				Fund
Undistributed net investment income		$	(2,007	)		$	(10,067	)		$	(1,267	)
Accumulated net realized gain (loss)			2,007				10,067				1,267

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, 2011 will expire as follows:

	Colorado			Minnesota			National
	Municipal			Municipal			Municipal
Year of Expiration	Fund			Fund II			Fund

5. Components of Net Assets on a Tax Basis (continued)

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.

For the six months ended September 30, 2011, the Funds had capital gains (losses), as follows, which may reduce (increase) the capital loss carryforwards:

Colorado	Minnesota	National
Municipal	Municipal	Municipal
Fund	Fund II	Fund
$136,455	$(154,606)	$89,734

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 six months ended September 30, 2011. Shares issuable under the Funds’ dividend reinvestment plan are purchased by the Funds’ transfer agent, BNY Mellon Shareowner Services, 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.

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 six months ended September 30, 2011, would have been as follows:

Net investment income		$1,309,770
Net realized gain on investments		254,675
Change in unrealized appreciation		4,271,078
Net increase in net assets resulting from operations		5,835,523

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 enhanced 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 September 30, 2011, 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. The value of these investments may be adversely affected by new legislation within the states, regional or local and national economic conditions, as applicable and differing levels of supply and demand for municipal bonds. Many municipalities insure repayment for their obligations. Although bond insurance reduces 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 September 30, 2011, 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	33%
Minnesota Municipal Fund II	20%
National Municipal Fund	19%

The Funds invest a portion of their assets in high yield fixed income securities, which carry ratings of BB or lower by Standard & Poor’s Rating Group (S&P) and/or Ba or lower by Moody’s Investors Service, Inc. (Moody’s). 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.

Notes to financial statements

Delaware Investments Closed-End Municipal Bond Funds

9. Credit and Market Risk (continued)

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 September 30, 2011, there were no Rule 144A securities and no securities have been determined to be illiquid under the Funds’ Liquidity Procedures.

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.

11. Investments in Municipal Securities Issued by the State of Arizona

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 September 30, 2011, municipal bonds issued by the state of Arizona constitute approximately 30% of the 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

On November 15, 2011, Delaware Investments Colorado Municipal Income Fund, Inc. (VCF) and Delaware Investments Minnesota Municipal Income Fund II, Inc. (VMM) issued $30,000,000 and $75,000,000, respectively, Series 2016 Variable Rate MuniFund Term Preferred (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.

Each Fund is obligated to redeem its VMTP Shares on December 1, 2016, unless earlier redeemed or repurchased by the Fund. VMTP Shares are subject to optional and mandatory redemption in certain circumstances. The VMTP Shares are subject to redemption at the option of a Fund, subject to payment of a premium until December 1, 2013, and at par thereafter. The Funds 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 (which are treated as interest payments for financial reporting purposes) are set weekly.

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 the Funds are 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), the Funds will pay additional fees with respect to the leverage.

Management has determined that no other material events or transactions occurred subsequent to September 30, 2011 that would require recognition or disclosure in the Funds’ financial statements.

Board Consideration of Delaware Investments Arizona Municipal Income Fund, Inc., Delaware Investments Colorado Municipal Income Fund, Inc., Delaware Investments National Municipal Income Fund and Delaware Investments Minnesota Municipal Income Fund II, Inc. Investment Advisory Agreement

At a meeting held on August 16-17, 2011 (the “Annual Meeting”), the Board of Directors (the “Board”), including a majority of disinterested or independent Directors, approved the renewal of the Investment Advisory Agreements for the Delaware Investments Arizona Municipal Income Fund, Inc.; Delaware Investments Colorado Municipal Income Fund, Inc.; Delaware Investments National Municipal Income Fund; and Delaware Investments Minnesota Municipal Income Fund II, Inc. (each, a “Fund” and together, the “Funds”). In making its decision, the Board considered information furnished specifically in connection with the renewal of the Investment Advisory Agreements with Delaware Management Company (“DMC”), which included materials provided by DMC and its affiliates (“Delaware Investments”) concerning, among other things, the nature, extent and quality of services provided to the Funds, the costs of such services to the Funds, economies of scale and the financial condition and profitability of Delaware Investments. In addition, in connection with the Annual Meeting, reports were provided in May 2011 and included independent historical and comparative reports provided by Lipper. The Lipper reports compared each Fund’s investment performance and expenses with those of other comparable mutual funds. The independent Directors reviewed and discussed the Lipper reports with independent legal counsel to the independent Directors. The Board requested and received information regarding DMC’s policy with respect to advisory fee levels and its breakpoint philosophy; the structure of portfolio manager compensation; the investment manager’s profitability; and any constraints or limitations on the availability of securities in certain investment styles, which had in the past year inhibited, or which were likely in the future to inhibit, DMC’s ability to invest fully in accordance with Fund policies.

In considering information relating to the approval of each Fund’s advisory agreement, the independent Directors received assistance and advice from and met separately with independent legal counsel to the independent Directors. Although the Board gave attention to all information furnished, the following discussion identifies, under separate headings, the primary factors taken into account by the Board during its contract renewal considerations.

Nature, Extent And Quality of Service. The Board considered the services provided by Delaware Investments to the Funds and their shareholders. In reviewing the nature, extent and quality of services, the Board considered reports furnished to it throughout the year, which covered matters such as the relative performance of each Fund, compliance of portfolio managers with the investment policies, strategies and restrictions for each Fund, compliance by DMC (“Management”) personnel with the Code of Ethics adopted throughout the Delaware Investments Family of Funds complex and adherence to fair value pricing procedures as established by the Board. The Board was pleased with the current staffing of the Funds’ investment advisor and the emphasis placed on research in the investment process. The Board gave favorable consideration to DMC’s efforts to control expenditures while maintaining service levels committed to fund matters. The Board was satisfied with the nature, extent and quality of the overall services provided by Delaware Investments.

Investment Performance. The Board placed significant emphasis on the investment performance of the Funds in view of its importance to shareholders. Although the Board gave appropriate consideration to performance reports and discussions with portfolio managers at Board meetings throughout the year, the Board gave particular weight to the Lipper reports furnished for the Annual Meeting. The Lipper reports prepared for each Fund showed the investment performance of its shares in comparison to a group of similar funds as selected by Lipper (the “Performance Universe”). A fund with the highest performance ranked first, and a fund with the lowest ranked last. The highest/best performing 25% of funds in the Performance Universe make up the first quartile; the next 25%, the second quartile; the next 25%, the third quartile; and the lowest/worst performing 25% of funds in the Performance Universe make up the fourth quartile. Comparative annualized performance for each Fund was shown for the past one-, three-, five- and ten-year periods ended March 31, 2011. The Board’s objective is that each Fund’s performance for the periods considered be at or above the median of its Performance Universe. The following paragraphs summarize the performance results for the Funds and the Board’s view of such performance.

Delaware Investments Arizona Municipal Income Fund, Inc. – The Performance Universe for the Fund consisted of the Fund and all closed–end other state municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund’s total return for the one-year period was in the second quartile. The report further showed that the Fund’s total return for the three-, five- and ten-year periods was in the fourth quartile of its Performance Universe. The Fund’s performance results were mixed. However, in evaluating the Fund’s performance, the Board considered the Fund’s improved short term performance. The Board also noted the Fund’s pending reorganization. The Board was satisfied that Management was taking action to improve Fund performance and to meet the Board’s performance objective.

Delaware Investments Colorado Municipal Income Fund, Inc. – The Performance Universe for the Fund consisted of the Fund and all closed–end other state municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund’s total return for the one-, three-, five- and ten-year periods was in the fourth quartile of its Performance Universe. The Fund’s performance results were not in line with the Board’s objective. In evaluating the Fund’s performance, the Board considered the fact that the Fund was currently an unlevered fund measured within a levered peer group, and noted that Management was pursuing leverage opportunities for the Fund.

Delaware Investments Minnesota Municipal Income Fund II, Inc. – The Performance Universe for the Fund consisted of the Fund and all closed–end other state municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund’s total return for the three- and five-year periods was in the fourth quartile of its Performance Universe. The report further showed that the Fund’s performance for the one- and ten-year periods was in the first and third quartiles, respectively. The Fund’s performance results were not in line with the Board’s objective. However, in evaluating

Other Fund information
(Unaudited)

Delaware Investments Closed-End Municipal Bond Funds (the “Funds”)

the Fund’s performance, the Board considered the Fund’s one-year performance results. The Board also considered the numerous investment and performance reports delivered by Management personnel to the Board’s Investments Committee. The Board was satisfied that Management was taking action to improve Fund performance and to meet the Board’s performance objective.

Delaware Investments National Municipal Income Fund – The Performance Universe for the Fund consisted of the Fund and all non-leveraged closed–end general and insured municipal debt funds as selected by Lipper. The Lipper report comparison showed that the Fund’s total return for the one-year period was in the third quartile. The report further showed that the Fund’s total return for the three- and five-year periods was ranked fourth of the four funds in the Performance Universes and the Fund’s total return for the ten-year period was ranked third out of the four funds in the Performance Universe. In evaluating the Fund’s performance, the Board considered the limited size of the Fund’s Performance Universe. The Board also considered the numerous investment and performance reports delivered by Management personnel to the Board’s Investments Committee. The Board was satisfied that Management was taking effective action to enhance Fund performance and meet the Board’s performance objective.

Comparative Expenses. The Board considered expense comparison data for the Delaware Investments Family of Funds. Management provided the Board with information on pricing levels and fee structures for each Fund as of its most recently completed fiscal year. The Board also focused on the comparative analysis of effective management fees and total expense ratios of each Fund versus effective management fees and expense ratios of a group of similar closed-end funds as selected by Lipper (the “Expense Group”). In reviewing comparative costs, each Fund’s contractual management fee and the actual management fee incurred by the Fund were compared with the contractual management fees (assuming all funds in the Expense Group were similar in size to the Fund) and actual management fees (as reported by each fund) within the Expense Group, taking into account any applicable breakpoints and fee waivers. Each Fund’s total expenses were also compared with those of its Expense Group. The Board considered fees paid to Delaware Investments for non-management services. The Board’s objective is to limit each Fund’s total expense ratio to be competitive with that of the Expense Group. The following paragraphs summarize the expense results for the Funds and the Board’s view of such expenses.

Delaware Investments Arizona Municipal Income Fund, Inc. – The expense comparisons for the Fund showed that its actual management fee and total expenses were in the quartile with the lowest expenses of its Expense Group. The Board was satisfied with the management fee and total expenses of the Fund in comparison to those of its Expense Group.

Delaware Investments Colorado Municipal Income Fund, Inc. – The expense comparisons for the Fund showed that its actual management fee and total expenses were in the quartile with the lowest expenses of its Expense Group. The Board was satisfied with the management fee and total expenses of the Fund in comparison to those of its Expense Group.

Delaware Investments Minnesota Municipal Income Fund II, Inc. – The expense comparisons for the Fund showed that its management fee and total expenses were in the quartile with the lowest expenses of its Expense Group. The Board was satisfied with the management fee and total expenses of the Fund in comparison to those of its Expense Group.

Delaware Investments National Municipal Income Fund – The expense comparisons for the Fund showed that its management fee were ranked first of the three funds in the expense Group and its total expenses were ranked second of the three Funds in the Expense Group. In evaluating the Fund’s total expenses, the Board considered the limited number of funds in the Expense Group. The Board was satisfied with Management’s efforts to improve the Series’ total expense ratio and bring it in line with the Board’s objective.

Management Profitability. The Board considered the level of profits, if any, realized by Delaware Investments in connection with the operation of the Funds. In this respect, the Board reviewed the Investment Management Profitability Analysis that addressed the overall profitability of Delaware Investments’ business in providing management and other services to each of the individual funds and the Delaware Investments Family of Funds as a whole. Specific attention was given to the methodology followed in allocating costs for the purpose of determining profitability. Management stated that the level of profits of Delaware Investments, to a certain extent, reflect recent operational cost savings and efficiencies initiated by Delaware Investments. The Board considered Delaware Investments’ efforts to improve services provided to fund shareholders and to meet additional regulatory and compliance requirements resulting from recent industry-wide Securities and Exchange Commission initiatives. The Board also considered the extent to which Delaware Investments might derive ancillary benefits from fund operations, including the potential for procuring additional business as a result of the prestige and visibility associated with its role as service provider to the Delaware Investments Family of Funds and the benefits from allocation of fund brokerage to improve trading efficiencies. The Board found that the management fees were reasonable in light of the services rendered and the profitability of Delaware Investments.

Economies of Scale. As closed-end funds, the Funds do not issue shares on a continuous basis. Fund assets increase only to the extent that the values of the underlying securities in the Fund increase. Accordingly, the Board determined that each Fund was not likely to experience significant economies of scale due to asset growth and, therefore, a fee schedule with breakpoints to pass the benefit of economies of scale on to shareholders was not likely to provide the intended effect.

Change in Independent Registered Public Accounting Firm. Due to independence matters under the Securities and Exchange Commission’s auditor independence rules relating to the January 4, 2010 acquisition of Delaware Investments (including DMC) by Macquarie Group, Ernst & Young LLP (E&Y) has resigned as the independent registered public accounting firm for Delaware Investments Colorado Municipal Income Fund, Inc., Delaware Investments Minnesota Municipal Income Fund II, Inc., and Delaware Investments National Municipal Income Fund (the Funds) effective May 27, 2010. At a meeting held on February 18, 2010, the Board of Directors/Trustees of the Funds, upon recommendation of the Audit Committee, selected PricewaterhouseCoopers LLP (PwC) to serve as the independent registered public accounting firm for the Funds for the fiscal year ended March 31, 2011. During the fiscal years ended March 31, 2010 and 2009, E&Y’s audit reports on the financial statements of the Funds did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. In addition, there were no disagreements between the Funds and E&Y on accounting principles, financial statements disclosures or audit scope, which, if not resolved to the satisfaction of E&Y, would have caused them to make reference to the disagreement in their reports. None of the Funds nor anyone on their behalf has consulted with PwC at any time prior to their selection with respect to the application of accounting principles to a specified transaction, either completed or proposed or the type of audit opinion that might be rendered on the Funds’ financial statements.
