Delaware Investments Closed-End Municipal Bond Funds

The 12-month fiscal period ended March 31, 2010, was a favorable one for the Funds and for investors in tax-exempt debt in general. The strong conditions came after two very challenging years for the municipal bond market.

National economic environment

On the heels of a historically difficult prior fiscal period, the stage was set for a strong “snapback” recovery. Such a recovery came to fruition for the municipal market (as well as the broader fixed income and equity markets) early during the fiscal period. In our view, this recovery was the defining element of the period. For example, investors’ extreme risk aversion eased within weeks of the start of the period — slowly at first, and more quickly as the year progressed. The series of aggressive actions taken by the federal government as well as the Federal Reserve helped to usher in the improved conditions. In December 2008, for example, the Fed cut its target federal funds rate to a range of 0–0.25%, an all-time low. The Fed kept that policy in place throughout the Funds’ fiscal year. For its part, the federal government passed the Troubled Asset Relief Program (TARP) — a $700 billion package designed to shore up financial institutions — in October 2008. The passage and implementation of the American Recovery and Reinvestment Act of 2009, a $787 billion economic stimulus package, in February 2009 also helped to ease economic distress during the Funds’ fiscal year.

By the second quarter of 2009, the worst economic and market conditions appeared to have passed, with the U.S. economy declining by an annual rate of just 0.7%. In the third quarter, gross domestic product turned to growth and expanded at an annualized 2.2% pace, while fourth-quarter growth was estimated at an annual rate of 5.9% — the best result in six years. Despite these favorable signs, joblessness remained historically high. In January 2010, the national unemployment rate stood at 9.7%; this figure was below the October 2009 peak of 10.1%, but well above the 8.2% at the start of the fiscal period. (Data for economic growth: Bureau of Economic Analysis; Employment data: Bloomberg.)

Municipal market trends

Early in the reporting period, municipal bond investors remained highly cautious. They tended to favor higher-rated securities, as these securities face limited credit risk, and shorter-maturity securities, as these bonds are typically subject to diminished interest rate risk. But as the evidence of an improving economy mounted early during the fiscal period, investors began to turn toward bonds offering the prospect of higher returns, albeit with greater risk. The rally gathered momentum in subsequent months thanks in part to a favorable technical environment that generally grew stronger throughout the annual period. The technical developments can be summarized in a few main points:

Demand for municipal bonds was robust. The $80 billion in net inflows into tax-exempt bond mutual funds in calendar year 2009 more than doubled the previous record. (Source: Barclays Capital.)
Although bond issuance approached a new record as well, supply of tax-exempt debt was limited by the introduction of Build America Bonds, or BABs. These bonds represent a relatively new category of taxable debt, with federally subsidized income payments. While they provided municipal issuers with an attractive alternative to traditional tax-exempt bonds, the surge in issuance of BABs continued diverting supply away from the tax-exempt market.
Within this environment, the 2-to-30-year yield curve flattened during the year. Yields at the short end remained anchored by the fed funds rate. Yet, driven by this combination of strong demand and constrained municipal supply, yields on longer-maturity bonds declined during the period. (It is important to remember that bond yields move in the opposite direction of bond prices.)

Medium- and lower-rated municipal bonds significantly outperformed their higher-rated counterparts during the Funds’ fiscal year. Credit spreads, often viewed as a way to determine a security or asset class’s perceived level of risk, narrowed from historically high levels at the start of the fiscal period. For example, municipal bond spreads (on Baa-rated bonds) declined from 2.39 percentage points above “prime-rated” Aaa securities at the start of the period to

1.43 percentage points at the end of the fiscal period. Such a decline represented investors’ increased willingness to accept “risky” securities during the fiscal period. (Source: Bloomberg.)

Similar trends occurred when viewing the municipal market on a sector-by-sector basis. Namely, credits within traditionally higher-risk sectors, such as industrial development revenue (IDR), hospital, and housing bonds significantly outperformed lower-risk areas like pre-refunded bonds. (Source: Barclays Capital.) Pre-refunded bonds are found on the short end of the yield curve and have historically faced little, if any, credit risk because they are backed by the invested debt proceeds of a second bond issue, typically U.S. Treasury securities.

Fund positioning

At the beginning of the fiscal year, the Funds were allocated relatively defensively, with an emphasis on higher-rated, shorter-maturity bonds. A significant portion of the Funds’ holdings (approximately 30% across each Fund) was invested in pre-refunded securities, which, as noted above, tend to be among the least risky bonds in the municipal marketplace.

As risk tolerance re-emerged during the course of the year, we saw what we felt was an unusually attractive opportunity to gradually and methodically tilt the Funds’ portfolios toward a slightly more aggressive stance. Especially during the second and third calendar quarters of 2009, a number of new, lower-rated investment grade issues came to market that offered much-higher-than-usual levels of income at what we believed were still very attractive prices. This provided us with a dual opportunity to trade out of some of the Funds’ more defensive holdings (many of which were scheduled to mature in the coming years) for more-aggressively positioned bonds that we felt offered attractive yields and good long-term value potential for our shareholders.

More specifically, many of our new purchases across each of the Funds involved medium- and lower-medium-grade A-rated and BBB-rated issues in the healthcare, education, and transportation sectors. Additionally, we sold some of the Funds’ shorter-maturity bonds — especially those with maturities of five years or less — and replaced them with 30-year and longer bonds.

By the final quarter of 2009 and in early 2010, we had essentially completed our repositioning and began to note relatively fewer value opportunities available in the marketplace. We had sold a significant portion of our exposure to high-quality, short-maturity debt — the pre-refunded bond allocation across our closed-end funds, for example, fell to roughly 10% from 30% at the start of the fiscal year — and remained more aggressively positioned at period end.

Performance effects

Our decision to move the Funds toward a more aggressive stance proved a fruitful one when comparing each Fund’s Performance to that of its benchmark index. The types of holdings we emphasized during much of the year experienced strong returns relative to the broader municipal market.

Our best individual performers during the fiscal period largely fit the profile of the types of securities that tended to outperform during the period. Namely, they were mid- to low-investment-grade securities with long (20-plus years) maturities.

For example, a Pima County, Ariz., industrial development revenue (IDR) bond issued for the Tucson Country Day School was a top performer within Delaware Investments Arizona Municipal Income Fund, Inc. This bond was unrated by Moody’s and rated BBB- (lower medium grade) by Standard & Poor’s, and is due to mature in 2037. IDR bonds were among the top performers within Delaware Investments Colorado Municipal Income Fund, Inc. and Delaware Investments Minnesota Municipal Income Fund II, Inc. Within the Colorado Fund IDR bonds issued for the Colorado Convention Center in Denver rated Baa3/ BBB- by Moody’s and S&P, respectively, which mature in 2035, added to returns. Within the Minnesota Fund, IDR bonds issued for International Paper boosted the Fund’s return. These bonds are rated Baa3/BBB and mature in 2027.

The strongest performer within Delaware Investments National Municipal Income Fund came from a different sector — student housing — though it shared similar rating and maturity profiles with those of the aforementioned bonds. These bonds were issued by the Maryland State Economic Development Corporation for the University of Maryland College Park. The bonds are due to mature in 2033 and are rated Baa2 by Moody’s (unrated by S&P).

The Funds’ weakest individual performers relative to the index tended to be higher-rated, shorter-maturity bonds. For example, three of the Funds’ worst-performing bonds during the year were pre-refunded bonds. Within Delaware Investments Arizona Municipal Income Fund, Inc., pre-refunded bonds issued by the Commonwealth of Puerto Rico (which are exempt from federal, state, and local income taxes in all 50 states) detracted from returns, whereas pre-refunded bonds issued by the Colorado Educational and Cultural Facilities Authority to benefit student housing at the University of Colorado detracted from returns within Delaware Investments Colorado Municipal Income Fund, Inc.

Within Delaware Investments Minnesota Municipal Income Fund II, Inc, pre-refunded bonds issued by the Minneapolis Community Development Agency weakened the Fund’s return. Within Delaware Investments National Municipal Income Fund, a Virginia state general obligation bond notably hurt the Fund’s return. Unlike the weaker performers mentioned above, this bond was not pre-refunded; instead, it was largely punished by investors for its high credit quality (rated Aaa/AAA by Moody’s and S&P, respectively) during a period when lower-rated, higher-risk securities were most in demand.

Economic environments by state

Arizona

The Arizona economy has slowed significantly due to the housing crisis, with employment figures down significantly from their peak in 2007.

Arizona ended fiscal 2009 with a general fund balance of negative $455.9 million, down from a positive $237.3 million in fiscal 2008. Its budget stabilization fund is fully depleted. Additionally, the state is dealing with limited financial flexibility as a result of voter mandates and constitutional constraints. For example, 73% of the state’s General Fund Budget is protected from reductions due to either the federal stimulus or voter constraints. (Sources: Bureau of Labor Statistics, azcentral.com, Arizona 2008 and 2009 Comprehensive Annual Financial Report, and Moody’s.)

Colorado

As of February 2010 (latest data available), unemployment in Colorado was 7.7%, well below the national rate of 9.7%. The state’s economy is diverse, with below-average employment concentration in manufacturing and a variety of service-sector strengths. Its economic outlook is favorable, reflecting a growing population and work force, relatively low costs of living and doing business, and a mix of technology and service industries. Additionally, Colorado is a wealthy state, with per capita income that’s above the U.S. average.

Fiscal 2009, state-generated general fund revenues totaled $11.2 billion, a 0.3% increase over 2008. Colorado ended fiscal 2009 with a general fund balance of $335 million, up from $207 million in fiscal 2008. Colorado’s Required Statutory Reserve declined $3.5 million to total $148.2 million. (Sources: Bureau of Labor Statistics, The Denver Post, Colorado 2008 and 2009 Comprehensive Annual Financial Report, and Moody’s.)

Minnesota

Unemployment in Minnesota in February 2010 was 7.3%, well below the national rate of 9.7%. Two-thirds of the jobs lost in the state over the past two years have been in the manufacturing, construction, and retail trade sectors. These three industries are projected to regain only about one-quarter of their losses over the next two years.

Minnesota currently faces a budget deficit of $994 million for the 2010-2011 biennium, or 3.2% of projected biennial expenditures. The State House and Senate recently fixed about one-third of the budget problem by passing a bill that cut spending by $312 million. The budget bill cut funding for local governments, colleges and universities, environmental and natural resource programs, economic development, bus operations, courts, prisons, and state agencies.

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.

3 Ratio reflects total net investment income less dividends paid to preferred shareholders divided by average net assets applicable to common shareholders.

4 In 2008, the Fund redeemed all of its preferred shares at par plus accumulated dividends amounting to $25,024,395. See Note 7 in “Notes to financial statements.”

Delaware Investments Closed-End Municipal Bond Funds

March 31, 2010

Delaware Investments Arizona Municipal Income Fund, Inc. (Arizona Municipal Fund), 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). Arizona Municipal Fund, 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 Fund, except National Municipal Income Fund will 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.

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 by an independent pricing service or broker. 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, 2007 – March 31, 2010), and has concluded that no provision for federal income tax is required in the Funds’ financial statements.

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

Interest and Related Expenses — Interest and related expenses include, but are not limited to, interest expense, remarketing fees, liquidity fees, and trustees’ fees of inverse floater programs in which a Fund participates. In an inverse floater program, a Fund transfers 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, 2010.

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.

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, 2010.

On July 1, 2009, the Financial Accounting Standard Board (FASB) issued the FASB Accounting Standards Codification (Codification). The Codification became the single source of authoritative nongovernmental U.S. GAAP, superseding existing literature of the FASB, American Institute of Certified Public Accountants, Emerging Issues Task Force and other sources. The Codification is effective for interim and annual periods ending after September 15, 2009. The Funds adopted the Codification for the year ended March 31, 2010. There was no impact to financial statements as the Codification requirements are disclosure-only in nature.

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 average weekly net assets of each Fund.

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

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, 2010, the Funds were charged as follows:

Arizona		Colorado		Minnesota		National
Municipal		Municipal		Municipal		Municipal
Fund		Fund		Fund II		Fund
$	2,014	$	3,325	$	7,938	$	1,544

At March 31, 2010, each Fund had liabilities payable to affiliates as follows:

	Arizona		Colorado		Minnesota		National
	Municipal		Municipal		Municipal		Municipal
	Fund		Fund		Fund II		Fund
Investment management fee payable to DMC	$	14,020	$	23,047	$	55,232	$	10,784
Accounting administration and other expenses
payable to DSC		179		288		707		138
Other expenses payable to DMC and affiliates*		418		30,385		1,644		321

*DMC, as part of its administrative services, pays operating expenses on behalf of each Fund and is reimbursed on a periodic basis. Such expenses include items such as printing of shareholder reports, fees for audit, legal and tax services, stock exchange fees, custodian 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 year ended March 31, 2010, each Fund was charged for internal legal and tax services provided by DMC and/or its affiliates’ employees as follows:

Arizona		Colorado		Minnesota		National
Municipal		Municipal		Municipal		Municipal
Fund		Fund		Fund II		Fund
$	3,121	$	5,156	$	12,309	$	2,393

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 Funds. These officers and Directors/Trustees are paid no compensation by the Funds.

3. Investments

For the year ended March 31, 2010, the Fund made purchases and sales of investment securities other than short-term investments as follows:

	Arizona		Colorado		Minnesota		National
	Municipal		Municipal		Municipal		Municipal
	Fund		Fund		Fund II		Fund
Purchases	$	9,832,332	$	13,637,475	$	31,062,260	$	21,131,602
Sales		7,876,326		12,898,561		29,846,597		20,828,960

At March 31, 2010, the cost of investments and unrealized appreciation (depreciation) for federal income tax purposes for each Fund were as follows:

	Arizona				Colorado				Minnesota				National
	Municipal				Municipal				Municipal				Municipal
	Fund				Fund				Fund II				Fund
Cost of investments		$	40,303,944			$	66,169,368			$	154,385,698			$	30,976,220
Aggregate unrealized appreciation		$	1,088,737			$	2,401,823			$	7,375,049			$	1,269,279
Aggregate unrealized depreciation			(1,010,857	)			(1,172,928	)			(1,688,217	)			(315,416	)
Net unrealized appreciation		$	77,880			$	1,228,895			$	5,686,832			$	953,863

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-tier hierarchy of inputs is summarized below.

Level 1 – inputs are quoted prices in active markets

Level 2 – inputs are observable, directly or indirectly

Level 3 – inputs are unobservable and reflect assumptions on the part of the reporting entity

The following table summarizes the valuation of each Fund’s investments by the fair value hierarchy levels as of March 31, 2010:

	Arizona Municipal Fund
	Level 2
Municipal Bonds		$	40,381,824
Total		$	40,381,824

	Colorado Municipal Fund
	Level 2
Municipal Bonds		$	67,298,263
Short-Term			100,000
Total		$	67,398,263

	Minnesota Municipal Fund II
	Level 2
Municipal Bonds		$	160,072,530
Total		$	160,072,530

	National Municipal Fund
	Level 2
Municipal Bonds		$	31,630,083
Short-Term			300,000
Total		$	31,930,083

There were no Level 3 securities at the beginning or end of the period.

In January 2010, the FASB issued an Accounting Standards Update, Improving Disclosures about Fair Value Measurements, which introduces new disclosure requirements and clarifies certain existing disclosure requirements around fair value measurements currently presented above. The new disclosures and clarifications of existing disclosures are generally effective for each Fund’s year ending March 31, 2010 and interim periods therein. Management is evaluating the impact of this update on its current disclosures.

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, 2010 and March 31, 2009 was as follows:

	Arizona			Colorado			Minnesota			National
	Municipal			Municipal			Municipal			Municipal
	Fund			Fund			Fund II			Fund
Year Ended 3/31/10
Ordinary income		$	—		$	—		$	—		$	18,011
Tax-exempt income			1,438,912			2,757,147			6,557,836			1,217,311
Long-term capital gain			74,555			—			—			—
Total		$	1,513,467		$	2,757,147		$	6,557,836		$	1,235,322

Year Ended 3/31/09
Ordinary income		$	129,029		$	319,989		$	637,277		$	92,304
Tax-exempt income			2,090,880			3,691,139			8,705,599			1,692,283
Total		$	2,219,909		$	4,011,128		$	9,342,876		$	1,784,587

5. Components of Net Assets on a Tax Basis

As of March 31, 2010, the components of net assets on a tax basis were as follows:

	Arizona			Colorado				Minnesota				National
	Municipal			Municipal				Municipal				Municipal
	Fund			Fund				Fund II				Fund
Shares of beneficial interest		$	40,651,205		$	66,918,121			$	157,931,075			$	33,208,317
Undistributed ordinary income			580			—				—				—
Undistributed long-term capital gain			97,331			—				—				—
Undistributed tax-exempt income			268,364			176,704				362,513				145,793
Capital loss carryforwards			—			(672,918	)			(2,257,889	)			(2,649,375	)
Post-October losses			—			—				—				(8,470	)
Unrealized appreciation of investments			77,880			1,228,895				5,686,832				953,863
Net assets		$	41,095,360		$	67,650,802			$	161,722,531			$	31,650,128

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

Post-October losses represent losses realized on investment transactions from November 1, 2009 through March 31, 2010 that in accordance with federal income tax regulations, the Funds have elected to defer and treat as having arisen in the following year.

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 dividends and distributions, capital loss carryforward expiration and 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, 2010, the Funds recorded the following reclassifications:

	Arizona			Colorado			Minnesota			National
	Municipal			Municipal			Municipal			Municipal
	Fund			Fund			Fund II			Fund
Paid-in capital	$	—		$	—		$	(8,416	)	$	—
Undistributed net investment income		(11,209	)		(1,809	)		(3,902	)		(2,376	)
Accumulated net realized gain (loss)		11,209			1,809			12,318			2,376

For federal income tax purposes, capital loss carryforwards may be carried forward and applied against future capital gains. $221,375 and $980,028 was utilized in 2010 for Arizona Municipal Fund and Colorado Municipal Fund, respectively and $8,416 expired in 2010 for Minnesota Municipal Fund. Capital loss carryforwards remaining at March 31, 2010 will expire as follows:

	Colorado			Minnesota			National
	Municipal			Municipal			Municipal
Year of Expiration	Fund			Fund II			Fund
2013		$	—		$	9,826		$	—
2016			—			—			18,596
2017			672,918			1,983,869			1,770,984
2018			—			264,194			859,795
Total		$	672,918		$	2,257,889		$	2,649,375

6. Capital Stock

Pursuant to their articles of incorporation, Arizona Municipal Fund, 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, 2010. Shares issuable under the Funds’ dividend reinvestment plan are purchased by the Funds’ transfer agent, BNY Mellon Shareowner Services, in the open market.

For the year ended March 31, 2010, the Funds did not have any transactions in common shares.

7. Redemption of Preferred Shares

On October 7, 2008, the Funds’ Board approved a plan to redeem all outstanding preferred shares issued by the Funds. The plan was intended to better position each Fund to pursue its investment objectives in light of the unprecedented market volatility, which has resulted in higher short-term interest rates. Management recommended the redemption of the Funds’ preferred shares based on its expectation that at that time it may become increasingly difficult for the Funds to invest the assets attributable to the preferred shares in securities that provide a sufficient rate of return compared to the dividend rates payable on the preferred shares, which had remained elevated in recent remarketings. These higher costs, in conjunction with market conditions at that time, could cause the Funds to realize an overall lower rate of return than if the Funds were not leveraged. Each Fund’s Board may consider adding some form of leverage to the Funds in the future if warranted by economic conditions at that time.

Prior to the redemption of the preferred shares, each Fund had a liquidation preference of $50,000 per share plus an amount equal to accumulated but unpaid dividends. The effective dates and redemption values are as follows:

	Shares Redeemed		Total

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 March 31, 2010, 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 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 the Funds. At March 31, 2010, the percentages of each Fund’s net assets insured by bond insurers are listed below:

Arizona Municipal Fund	35%
Colorado Municipal Fund	43%
Minnesota Municipal Fund II	25%
National Municipal Fund	41%

These securities have been identified in the statements of net assets.

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 Ratings 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, generally, to its first call date. 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 through 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 and 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.

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 assets. 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, 2010, 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 the Funds’ existing contracts and expects the risk of loss to be remote.

11. Delaware Investments National Municipal Income Fund – Investments in Municipal Securities Issued by the State of Florida

On September 13, 2007, shareholders of Delaware Investments National Municipal Income Fund (formerly Delaware Investments Florida Insured Municipal Income Fund) approved (1) the elimination of the Fund’s fundamental investment policy that required the Fund to invest primarily in insured municipal securities issued by the State of Florida and (2) the adoption of a new fundamental investment policy permitting the Fund to invest in un-insured municipal securities issued by states other than Florida. The Fund’s portfolio managers began to transition the Fund’s portfolio to include un-insured municipal bonds issued by other states and territories on October 15, 2007. As of March 31, 2010, municipal bonds issued by the State of Florida constitute approximately 35% of the Fund’s portfolio. These investments could make the Fund more sensitive to economic conditions in Florida than other more geographically diversified national municipal income funds.

12. Sale of Delaware Investments to Macquarie Group

On August 18, 2009, Lincoln National Corporation (former parent company of Delaware Investments) and Macquarie Group (Macquarie) entered into an agreement pursuant to which Delaware Investments, including DMC and DSC, would be acquired by Macquarie, an Australia-based global provider of banking, financial, advisory, investment and funds management services (Transaction). The Transaction was completed on January 4, 2010. DMC and DSC are now wholly owned subsidiaries of Macquarie.

The Transaction resulted in a change of control of DMC which, in turn, caused the termination of the investment management agreement between DMC and the Funds. On January 4, 2010, the new investment management agreement between DMC and the Funds that was approved by the shareholders became effective.

The Shareholders and Board of Directors/Trustees of
Delaware Investments Arizona Municipal Income Fund, Inc.
Delaware Investments Colorado Municipal Income Fund, Inc.
Delaware Investments Minnesota Municipal Income Fund II, Inc.
Delaware Investments National Municipal Income Fund

We have audited the accompanying statements of net assets and statements of assets and liabilities of Delaware Investments Arizona Municipal Income Fund, Inc., Delaware Investments Colorado Municipal Income Fund, Inc., Delaware Investments Minnesota Municipal Income Fund II, Inc., and Delaware Investments National Municipal Income Fund (the “Funds”) as of March 31, 2010, and the related statements of operations for the year then ended, the statements of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Funds’ management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Funds’ internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of March 31, 2010 by correspondence with the custodian and brokers or by other appropriate auditing procedures when replies from brokers were not received. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of each of the respective Funds at March 31, 2010, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended, and their financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

In a press release on August 19, 2009, Lincoln National Corporation announced that one of its subsidiaries signed a stock purchase agreement to sell ownership of Delaware Management Holdings, Inc. and its subsidiaries (also known by the marketing name of Delaware Investments), including Delaware Management Company, a series of Delaware Management Business Trust (the “Manager”), to Macquarie Group (the “Transaction”). On January 4, 2010, the Transaction was completed and the new investment advisory agreements between each Fund and the Manager that were approved by the shareholders became effective. Delaware Management Holdings, Inc. is a subsidiary, and subject to the ultimate control, of Macquarie Group. Macquarie Group, with headquarters in Sydney, Australia, is a global provider of banking, financial, advisory, investment and fund management services.

Dividend Reinvestment Plan

Each Fund offers an automatic dividend reinvestment program (“Plan”). Under the current policies of Arizona Municipal Income Fund, Minnesota Municipal Income Fund II, and National Municipal Income Fund all distributions of net investment income and capital gains to common shareholders are automatically reinvested in additional shares unless shareholders elect to receive all dividends and other distributions in cash paid by check mailed directly to shareholders by the dividend plan agent. Under the current policies of Colorado Municipal Income Fund, distributions of net investment income and capital gains to common shareholders will be paid in cash unless shareholders notify BNY Mellon Investor Services, Inc. (“BNY Mellon”) of their desire to participate in the dividend reinvestment program. Shareholders who hold their shares through a bank, broker or other nominee should request the bank, broker or nominee to participate in the Plan on their behalf. This can be done as long as the bank, broker or nominee provides a dividend reinvestment service for the Funds. If the bank, broker or nominee does not provide this service, such shareholders must have their shares taken out of “street” or nominee name and re-registered in their own name in order to participate in the Plan.

BNY Mellon will apply all cash dividends, capital gains and other distributions (collectively, “Distributions”) on each Fund’s shares of common stock which become payable to each Plan participant to the purchase of outstanding shares of each Fund’s common stock for such participant. These purchases may be made on a securities exchange or in the over-the-counter market, and may be subject to such terms of price, delivery and related matters to which BNY Mellon may agree. The Funds will not issue new shares in connection with the Plan.

Distributions reinvested for participants are subject to income taxes just as if they had been paid directly to the shareholder in cash. Participants will receive a year-end statement showing distributions reinvested, and any brokerage commissions paid on such participant’s behalf.

Shareholders holding shares of a Fund in their own names who wish to terminate their participation in the Plan may do so by sending written instruction to BNY Mellon so that BNY Mellon receives such instructions at least 10 days prior to the Distribution record date. Shareholders with shares held in account by a bank, broker or other nominee should contact such bank, broker or other nominee to determine the procedure for withdrawal from the Plan.

If written instructions are not received by BNY Mellon at least 10 days prior to the record date for a particular Distribution, that Distribution may be reinvested at the sole discretion of BNY Mellon. After a shareholder’s instructions to terminate participation in the Plan become effective, Distributions will be paid to shareholders in cash. Upon termination, a shareholder may elect to receive either stock or cash for all the full shares in the account. If cash is elected, BNY Mellon will sell such shares at the then current market value and then send the net proceeds to the shareholder, after deducting brokerage commissions and related expenses. Any fractional shares at the time of termination will be paid in cash at the current market price, less brokerage commissions and related expenses, if any. Shareholders may at any time request a full or partial withdrawal of shares from the Plan, without terminating participation in the Plan. When shares outside of the Plan are liquidated, Distributions on shares held under the Plan will continue to be reinvested unless BNY Mellon is notified of the shareholder’s withdrawal from the Plan.

Board Consideration of New Investment Advisory Agreement

At a meeting held on September 3, 2009 (the “Meeting”), the Board of Directors of the Delaware Investments Family of Funds (the “Board”), including the independent Directors, unanimously approved a new investment advisory agreement between each registrant on behalf of each series (each, a “Fund” and together, the “Funds”) and Delaware Management Company (“DMC”) in connection with the sale of Delaware Investments’ advisory business to Macquarie Bank Limited (the “Macquarie Group”) (the “Transaction”). In making its decision, the Board considered information furnished specifically in connection with the approval of the new investment advisory agreements with DMC (the “New Investment Advisory Agreements”), which included extensive materials about the Transaction and matters related to the proposed approvals. To assist the Board in considering the New Investment Advisory Agreements, Macquarie Group provided materials and information about Macquarie Group, including detailed written responses to the questions posed by the independent Directors. DMC also provided materials and information about the Transaction, including detailed written responses to the questions posed by the independent Directors.

At the Meeting, the Directors discussed the Transaction with DMC management and with key Macquarie Group representatives. The Meeting included discussions of the strategic rationale for the Transaction and Macquarie Group’s general plans and intentions regarding the Funds and DMC. The Board members also inquired about the plans for, and anticipated roles and responsibilities of, key employees and officers of Delaware Management Holdings Inc. and DMC in connection with the Transaction.

In connection with the Directors’ review of the New Investment Advisory Agreements for the Funds, DMC and/or Macquarie Group emphasized that:

They expected that there would be no adverse changes as a result of the Transaction, in the nature, quality, or extent of services currently provided to the Funds and their shareholders, including investment management, distribution, or other shareholder services.
No material changes in personnel or operations were contemplated in the operation of DMC under Macquarie Group as a result of the Transaction and no material changes were currently contemplated in connection with third party service providers to the Funds.
Macquarie Group had no intention to cause DMC to alter the voluntary expense waivers and reimbursements currently in effect for the Funds.
Under the agreement between Macquarie Group and Lincoln National Corporation (“LNC”) (the “Transaction Agreement”), Macquarie Group has agreed to conduct, and to cause its affiliates to conduct, their respective businesses in compliance with the conditions of Section 15(f) of the Investment Company Act of 1940 (the “1940 Act”) with respect to the Funds, to the extent within its control, including maintaining Board composition of at least 75% of the Board members qualifying as independent Directors and not imposing any “unfair burden” on the Funds for at least two years from the closing of the Transaction (the “Closing”).

In addition to the information provided by DMC and Macquarie Group as described above, the Directors also considered all other factors they believed to be relevant to evaluating the New Investment Advisory Agreements, including the specific matters discussed below. In their deliberations, the Directors did not identify any particular information that was controlling, and different Directors may have attributed different weights to the various factors. However, for each Fund, the Directors determined that the overall arrangements between the Fund and DMC, as provided in the respective New Investment Advisory Agreement, including the proposed advisory fee and the related administration arrangements between the Fund and DMC, were fair and reasonable in light of the services to be performed, expenses incurred, and such other matters as the Directors considered relevant. Factors evaluated included:

The potential for expanding distribution of Fund shares through access to Macquarie Group’s existing distribution channels;
Delaware Investments’ acquisition of an exclusive wholesaling sales force from a subsidiary of LNC;
The reputation, financial strength, and resources of Macquarie Group as well as its historic and ongoing commitment to the asset management business in Australia as well as other parts of the world;

The terms and conditions of the New Investment Advisory Agreements, including that each Fund’s total contractual fee rate under the New Investment Advisory Agreement will remain the same;
The Board’s full annual review (or initial approval) of the current investment advisory agreements at their in-person meeting in May 2009 as required by the 1940 Act and its determination that (i) DMC had the capabilities, resources, and personnel necessary to provide the satisfactory advisory and administrative services currently provided to each Fund and (ii) the advisory and/or management fees paid by each Fund, taking into account any applicable fee waivers and breakpoints, represented reasonable compensation to DMC in light of the services provided, the costs to DMC of providing those services, economies of scale, and the fees and other expenses paid by similar funds and such other matters that the Board considered relevant in the exercise of its reasonable judgment;
The portfolio management teams for the Funds are not currently expected to change as a result of the Transaction;
LNC and Macquarie Group were expected to execute a reimbursement agreement pursuant to which LNC and Macquarie Group would agree to pay (or reimburse) all reasonable out-of-pocket costs and expenses of the Funds in connection with the Board’s consideration of the Transaction, the New Investment Advisory Agreements and related agreements, and all costs related to the proxy solicitation (the “Expense Agreement”);
The likelihood that Macquarie Group would invest additional amounts in Delaware Investments, including DMC, which could result in increased assets under management, which in turn would allow some Funds the potential opportunity to achieve economies of scale and lower fees payable by Fund shareholders; and
The compliance and regulatory history of Macquarie Group and its affiliates.

In making their decision relating to the approval of each Fund’s New Investment Advisory Agreement, the independent Directors gave attention to all information furnished. The following discussion, however, identifies the primary factors taken into account by the Directors and the conclusions reached in approving the New Investment Advisory Agreements.

Nature, Extent, and Quality of Service. The Directors considered the services historically provided by DMC to the Funds and their shareholders. In reviewing the nature, extent, and quality of services, the Board considered that the New Investment Advisory Agreements would be substantially similar to the current investment advisory agreements between the Funds and DMC (the “Current Investment Advisory Agreements”), and they, therefore, considered the many reports furnished to them throughout 2008 and 2009 at regular Board meetings covering matters such as the relative performance of the Funds; the compliance of portfolio managers with the investment policies, strategies, and restrictions for the Funds; the compliance of management personnel with the code of ethics adopted throughout the Delaware Investments Family of Funds complex; and the adherence to fair value pricing procedures as established by the Board. The Directors were pleased with the current staffing of DMC and the emphasis placed on research and risk management in the investment process. Favorable consideration was given to DMC’s efforts to maintain expenditures and, in some instances, increase financial and human resources committed to Fund matters.

The Board was assured that shareholders would continue to receive the benefits provided to Fund shareholders by being part of the Delaware Investments Family of Funds. Based on the information provided by DMC and Macquarie Group, including that Macquarie Group and DMC currently expected no material changes as a result of the Transaction in (i) personnel or operations of DMC or (ii) third party service providers to the Funds, the Board concluded that the satisfactory nature, extent, and quality of services currently provided to the Funds and their shareholders were very likely to continue under the New Investment Advisory Agreements. The Board also concluded that it was very unlikely that any “unfair burden” would be imposed on any of the Funds for the first two years following the Closing as a result of the Transaction. Consequently, the Board concluded that it did not expect the Transaction to result in any adverse changes in the nature, quality, or extent of services (including investment management, distribution or other shareholder services) currently provided to the Funds and their shareholders.

Investment Performance. The Board considered the overall investment performance of DMC and the Funds. The Directors placed significant emphasis on the investment performance of the Funds in view of its importance to shareholders. Although the Directors gave appropriate consideration to performance reports and discussions with portfolio managers at Board meetings throughout the year, the Directors gave particular weight to their review of investment performance in connection with the approval of the Current Investment Advisory Agreements at the Board meeting held in May 2009. At that meeting, the Directors reviewed reports prepared by Lipper, Inc., an independent statistical compilation organization (“Lipper”) which showed each Fund’s investment performance as of December 31, 2008 in comparison to a group of funds selected by Lipper as being similar to the Fund (the “Performance Universe”). During the May 2009 agreement review process, the Directors observed the significant improvements to relative investment performance of the Funds as compared to the Funds’ performance as of December 31, 2007.

Board Consideration of New Investment Advisory Agreement (continued)

At their meeting on September 3, 2009, the Directors, including the independent Directors in consultation with their independent counsel, reviewed the investment performance of each Fund. The Directors compared the performance of each Fund relative to that of its respective Performance Universe for the 1-, 3-, 5-, and 10-year periods ended June 30, 2009 and compared its relative investment performance against the corresponding relative investment performance of each Fund for such time periods ended December 31, 2008, to the extent applicable. As of June 30, 2009, 30 of the Funds had investment performance relative to that of the respective Performance Universe that was better than the corresponding relative investment performance at December 31, 2008 for all applicable time periods. At June 30, 2009, an additional 6 Funds had investment performance relative to that of their respective Performance Universe that was better than the corresponding relative investment performance at December 31, 2008 for a majority of the applicable time periods. At June 30, 2009, 15 additional Funds had investment performance relative to that of their respective Performance Universe that was better than the corresponding relative performance at December 31, 2008 and only 29 Funds had poorer relative investment performance at June 30, 2009 compared to that at December 31, 2008. The Board therefore concluded that the investment performance of the Funds on an aggregate basis had continued to improve relative to their respective Performance Universe since the data reviewed at the May 2009 meeting.

Delaware Investments Arizona Municipal Income Fund, Inc. – The Performance Universe for the Fund consisted of the Fund and all leveraged 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 second quartile of its Performance Universe. The Board was satisfied with performance.

Delaware Investments Colorado Municipal Income Fund, Inc. – The Performance Universe for the Fund consisted of the Fund and all leveraged 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 first quartile of its Performance Universe. The Board was satisfied with performance.

Delaware Investments Minnesota Municipal Income Fund II, Inc. – The Performance Universe for the Fund consisted of the Fund and all leveraged 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 first quartile of its Performance Universe. The Board was satisfied with performance.

Delaware Investments National Municipal Income Fund – The Performance Universe for the Fund consisted of the Fund and all leveraged closed–end general 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 first quartile. The report further showed that the Fund’s total return for the three-year period was in the second quartile and the Fund’s total return for the five- and ten-year periods was in the third quartile. The Board determined that the Fund’s performance results were mixed. In evaluating the Fund’s performance, the Board considered the strategy changes implemented in late 2007 and the improved performance for the one- and three-year periods. The Board was satisfied that Management was taking effective action to enhance Fund performance and meet the Board’s performance objective.

Based on information provided by DMC and Macquarie Group, the Board concluded that neither the Transaction nor the New Investment Advisory Agreement would likely have an adverse effect on the investment performance of any Fund because (i) DMC and Macquarie Group did not currently expect the Transaction to cause any material change to the Funds’ portfolio management teams responsible for investment performance, which the Board found to be satisfactory and improving; and (ii) as discussed in more detail below, the Funds’ expenses were not expected to increase as a result of the Transaction.

Comparative Expenses. The Directors also considered expense comparison data for the Funds previously provided in May 2009. At that meeting, DMC had provided the Board with information on pricing levels and fee structures for the Funds and comparative funds. The Directors focused on the comparative analysis of the effective management fees and total expense ratios of each Fund versus the effective management fees and expense ratios of a group of funds selected by Lipper as being similar to each Fund (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) of other funds within the Expense Group, taking into account any applicable breakpoints and fee limitations. Each Fund’s total expenses were also compared with those of its Expense Group. The Directors also considered fees paid to Delaware Investments for nonmanagement services. At the September 3, 2009 meeting, DMC advised the Board that the more recent comparative expenses for the Funds remained consistent with the previous review in May 2009 and, consequently, the Directors concluded that expenses of the Funds were satisfactory.

The Board also considered the Expense Agreement under negotiation in evaluating Fund expenses. The Directors expected that the Expense Agreement would provide that LNC and Macquarie Group would pay or reimburse the Funds for all reasonable out-of-pocket costs and expenses in connection with the Transaction and the consideration of the New Investment Advisory Agreements (subject to certain limited exceptions).

Based on information provided by DMC and Macquarie Group, the Board concluded that neither the Transaction nor the New Investment Advisory Agreements likely would have an adverse effect on the Funds’ expenses because (i) each Fund’s contractual fee rates under the New Investment Advisory Agreement would remain the same; (ii) under the Expense Agreement, the Funds would be reimbursed for all reasonable out-of-pocket costs and expenses in connection with the Transaction and the related proxy solicitation (subject to certain limited exceptions); and (iii) the expense ratios of certain Funds might decline as a result of the possible increased investment in Delaware Investments by Macquarie Group, as discussed below under “Economies of Scale.”

Management Profitability. At their meeting on September 3, 2009, the Board evaluated DMC’s profitability in connection with the operation of the Funds. The Board had previously considered DMC’s profitability in connection with the operation of the Funds at its May 2009 meeting. At that meeting, the Board reviewed an analysis that addressed the overall profitability of Delaware Investments’ business in providing management and other services to each of the 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.

At the May 2009 meeting, representatives of DMC had stated that the level of profits of DMC, to a certain extent, reflect operational cost savings and efficiencies initiated by Delaware Investments (including DMC and its affiliates that provide services to the Funds). 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 U.S. Securities and Exchange Commission initiatives. At that meeting, the Board found that the management fees were reasonable in light of the services rendered and the level of profitability of DMC. At the September 3, 2009 meeting, DMC advised the Board that DMC did not expect the Transaction to affect materially the profitability of Delaware Investments compared to the level of profitability considered during the May 2009 review. Moreover, the Directors reviewed pro forma balance sheets of certain key companies in Delaware Investments as of June 30, 2009 (which were provided by Macquarie Group and DMC in response to the Directors’ requests) and evaluated the projections of Delaware Investments’ capitalization following the Transaction for purposes of evaluating the financial ability of Delaware Investments to continue to provide the nature, extent, and quality of services as it had under the Current Investment Advisory Agreement.

Based on information provided by DMC and Macquarie Group, the Board concluded that DMC and Delaware Investments would be sufficiently capitalized following the Transaction to continue the same level and quality of services to the Funds under the New Investment Advisory Agreements as was the case under the Current Investment Advisory Agreements. The Board also concluded that Macquarie Group had sufficient financial strength and resources, as well as an ongoing commitment to a global asset management business, to continue investing in Delaware Investments, including DMC, to the extent that Macquarie Group determined it was appropriate. Finally, because services and costs were expected to be substantially the same (and DMC had represented that, correspondingly, profitability would be about the same), under the New Investment Advisory Agreements as under the Current Investment Advisory Agreements, the Directors concluded that the profitability of Delaware Investments would not result in an inequitable charge on the Funds or their shareholders. Accordingly, the Board concluded that the fees charged under the New Investment Advisory Agreements would be reasonable in light of the services to be provided and the expected profitability of DMC.

Economies of Scale. As a closed-end fund, 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 the Funds were 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.

The Board also acknowledged Macquarie Group’s statement that the Transaction would not by itself immediately provide additional economies of scale given Macquarie Group’s limited presence in the U.S. mutual fund market. Nonetheless, the Directors concluded that additional economies of scale could potentially be achieved in the future if DMC were owned by Macquarie Group as a result of Macquarie Group’s willingness to invest further in Delaware Investments if appropriate opportunities arise.

Fall-Out Benefits. The Board acknowledged that DMC would continue to benefit from soft dollar arrangements using portfolio brokerage of each Fund that invests in equity securities and that DMC’s profitability would likely be somewhat lower without the benefit of practices with respect to allocating Fund portfolio brokerage for brokerage and research services. The Board also considered that Macquarie Group and Delaware Investments may derive reputational, strategic, and other benefits from their association with the Delaware Investments Family of Funds, and evaluated 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. However, the Board concluded that (i) any such benefits under the New Investment Advisory Agreements would not be dissimilar from those existing under the Current Investment Advisory Agreements; (ii) such benefits did not impose a cost or burden on the Funds or their shareholders; and (iii) such benefits would probably have an indirectly beneficial effect on the Funds and their shareholders because of the added importance that DMC and Macquarie Group might attach to the Funds as a result of the fall-out benefits that the Funds conveyed.

Board Review of Macquarie Group. The Directors reviewed detailed information supplied by Macquarie Group about its operations as well as other information regarding Macquarie Group provided by independent legal counsel to the independent Directors. Based on this review, the Directors concluded that Delaware Investments would continue to have the financial ability to maintain the high quality of services required by the Funds. The Directors noted that there would be a limited transition period during which some services previously provided by LNC to Delaware Investments would continue to be provided by LNC after the Closing, and concluded that this arrangement would help minimize disruption in Delaware Investments’ provision of services to the Funds following the Transaction.

The Board considered Macquarie Group’s current intention to leave the Funds’ other service providers in place. The Board also considered Macquarie Group’s current strategic plans to increase its asset management activities, one of its core businesses, particularly in North America, and its statement that its acquisition of DMC is an important component of this strategic growth and the establishment of a significant presence in the United States. Based in part on the information provided by DMC and Macquarie Group, the Board concluded that Macquarie Group’s acquisition of Delaware Investments could potentially enhance the nature, quality, and extent of services provided to the Funds and their shareholders.

Board Consideration of New Investment Advisory Agreement (continued)

Conclusion. The Board concluded that the advisory fee rate under each New Investment Advisory Agreement was reasonable in relation to the services provided and that execution of the New Investment Advisory Agreement would be in the best interests of the shareholders. For each Fund, the Directors noted that they had concluded in their most recent advisory agreement continuance considerations in May 2009 that the management fees and total expense ratios were at acceptable levels in light of the quality of services provided to the Funds and in comparison to those of the Funds’ respective peer groups; that the advisory fee schedule would not be increased and would stay the same for all of the Funds; that the total expense ratio had not changed materially since that determination; and that DMC had represented that the overall expenses for each Fund were not expected to be adversely affected by the Transaction. The Directors also noted, with respect to the Funds that currently had the benefit of voluntary fee limitations, that Macquarie Group had no present intention to cause DMC to alter any voluntary expense limitations or reimbursements currently in effect. On that basis, the Trustees concluded that the total expense ratios and proposed advisory fees for the Funds anticipated to result from the Transaction were acceptable. In approving each New Investment Advisory Agreement, the Board stated that it anticipated reviewing the continuance of the New Investment Advisory Agreement in advance of the expiration of the initial two-year period.

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, DDLP and DSC) by Macquarie Group, Ernst & Young LLP (“E&Y”) will resign as the independent registered public accounting firm for Delaware Investments Arizona Municipal Income Fund, Inc., 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 LLC (“PwC”) to serve as the independent registered public accounting firm for each Fund for the fiscal year ending March 31, 2011. During the fiscal years ended March 31, 2009 and March 31, 2010, 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 any of 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.

This fee limit is based on aggregate fees to the investment adviser and its Control Affiliates.

Service	Range of Fees
Non-Audit Services
Services associated with periodic reports and other documents filed with the SEC and assistance in responding to SEC comment letters	up to $10,000 in the aggregate

The Pre-Approval Policy requires the registrant’s independent auditors to report to the Audit Committee at each of its regular meetings regarding all services initiated since the last such report was rendered, including those services authorized by the Pre-Approval Policy.

(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, John A. Fry, Thomas F. Madison, Janet L. Yeomans and J. Richard Zecher.

(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 ability to make 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”), a wholly owned subsidiary of RiskMetrics Group ("RiskMetrics"), 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/RiskMetrics’s proxy voting activities. If a proxy has been voted for the registrant, ISS/RiskMetrics 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 Web site at http://www.delawareinvestments.com; and (ii) on the Commission’s Web site at http://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 to create a new class of common stock with 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/RiskMetrics in accordance with the Procedures. Because almost all registrant proxies are voted by ISS/RiskMetrics 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/RiskMetrics’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/RiskMetrics 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 Frank Russell 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 Plan/Equity Compensation Plan - Portfolio managers may be awarded options, stock appreciation rights, restricted stock awards, restricted stock units, deferred stock units, and performance awards (collectively, “Awards”) relating to the underlying shares of common stock of Delaware Investments U.S., Inc. pursuant to the terms of the Delaware Investments U.S., Inc. 2009 Incentive Compensation Plan (the “Plan”) established on March 24, 2009. Since the establishment of the Plan, Awards are no longer granted under the Amended and Restated Delaware Investments U.S., Inc. Incentive Compensation Plan effective December 26, 2008, which was established in 2001.

The Plan was established 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. Shares issued typically must be held for six months and one day, after which time the stockholder may put them back to the company, subject to any applicable holding requirements. The fair market value of the shares of Delaware Investments U.S., Inc., is normally determined as of each March 31, June 30, September 30 and December 31. The fair market value of shares of common stock underlying Awards granted on or after December 26, 2008 is determined by an independent appraiser utilizing an appraisal valuation methodology in compliance with Section 409A of the Internal Revenue Code and the regulations promulgated thereunder.

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