SUMMARY OF ABBREVIATIONS: AMBAC - Insured by the AMBAC Assurance Corporation AMT - Subject to Alternative Minimum Tax FGIC - Insured by the Financial Guaranty Insurance Company FHA - Insured by the Federal Housing Administration FSA - Insured by Financial Security Assurance GNMA - Insured by Government National Mortgage Association LOC - Letter of Credit MBIA - Insured by the Municipal Bond Insurance Association RADIAN - Insured by Radian Asset Assurance ROLs - Residual Option Longs NOTES 1. SIGNIFICANT ACCOUNTING POLICIES The following accounting policies are in accordance with U.S. generally accepted accounting principles and are consistently followed by Delaware Investments Minnesota Municipal Income Fund III, Inc. (the "Fund"). SECURITY VALUATION - Long-term debt securities are valued by an independent pricing service and such prices are believed to reflect the fair value of such securities. Short-term debt securities having less than 60 days to maturity are valued at amortized cost, which approximates market value. 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 the Fund's Board of Directors. 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 with respect to foreign securities, aftermarket trading or significant events after local market trading (e.g., government actions or pronouncements, trading volume or volatility on markets, exchanges or among dealers, news events). FEDERAL INCOME TAXES - The Fund intends to continue to qualify for federal income tax purposes as a regulated investment company and make the requisite distributions to shareholders. Accordingly, no provision for federal income taxes has been made in the financial statements. USE OF ESTIMATES - The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. OTHER - Expenses common to all funds within the Delaware Investments Family of Funds are allocated amongst the 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). 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. The Fund declares and pays dividends from net investment income or other applicable sources monthly and distributions from net realized gain on investments, if any, annually. In addition, in order to satisfy certain distribution requirements of the Tax Reform Act of 1986, the Fund may declare special year-end dividend and capital gains distributions during November or December to shareholders of record on a date in such month. Such distributions, if received by shareholders by January 31, are deemed to have been paid by the Fund and received by shareholders on the earlier of the date paid for December 31 of the prior year. 2. INVESTMENTS At December 31, 2004, the cost of investments for federal income tax purposes has been estimated since the final tax characteristics cannot be determined until fiscal year end. At December 31, 2004, the aggregate cost of investments and gross unrealized appreciation (depreciation) for the Fund for federal income tax purposes was as follows: Aggregate cost of investments $38,345,507 ----------- Aggregate unrealized appreciation 2,252,951 Aggregate unrealized depreciation (22,131) ----------- Net unrealized appreciation $ 2,230,820 ----------- For federal income tax purposes, at March 31, 2004 capital loss carryforwards of $672,369 may be carried forward and applied against future capital gains. Such capital loss carryforwards expire as follows: $455,666 expires in 2005, $6,539 expires in 2006, $56,856 expires in 2008 and $153,308 expires in 2009. 3. CREDIT AND MARKET RISK The Fund concentrates its investments in securities issued by municipalities. The value of these investments may be adversely affected by new legislation within the state, regional or local economic conditions, 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. These securities have been identified in the Schedule of Investments. The Funds may invest in inverse floating rate securities ("inverse floaters"), a type of derivative tax-exempt obligation 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 inverse floaters will generally be more volatile than other tax-exempt investments. Such securities are denoted on the Statements of Net Assets. ITEM 2.
