Notes to Financial STATEMENTS (unaudited as to February 28, 2006)

(1) Organization	Minnesota Municipal Income Portfolio Inc. (the "fund") is registered under the Investment Company Act of 1940 (as amended) as a non-diversified, closed-end management investment company. The fund invests primarily in Minnesota municipal securities that, at the time of purchase, are rated investment grade or are unrated and deemed to be of comparable quality by U.S. Bancorp Asset Management, Inc. ("USBAM"). The fund may invest up to 5% of its total assets in municipal securities that, at the time of purchase, are rated lower than investment grade or are unrated and deemed to be of comparable quality by USBAM. The fund will not invest in municipal securities that, at the time of purchase, are rated lower than B or are unrated and deemed to be of comparable quality by USBAM. Municipal securities in which the fund invests may include municipal derivative securities, such as inverse floating rate and inverse interest-only municipal securities. The f und's investments also may include futures contracts, options on futures contracts, options, and interest rate swaps, caps, and floors. Although the fund is authorized to invest in the financial instruments mentioned in the preceding two sentences, and may do so in the future, the fund did not make any such investments during the six-month period ended February 28, 2006. Fund shares are listed on the American Stock Exchange under the symbol MXA.
	The fund concentrates its investments in Minnesota and therefore may have more credit risk related to the economic conditions of Minnesota than a portfolio with a broader geographical diversification.
	On June 22, 2005 the fund's board of directors approved a change in the fund's fiscal year-end from January 31 to August 31, effective with the seven-month fiscal period ended August 31, 2005.
(2) Summary of Significant Accounting Policies	Security Valuations
	Security valuations for the fund's investments are furnished by one or more independent pricing services that have been approved by the fund's board of directors. Debt obligations exceeding 60 days to maturity are valued by an independent pricing service. The pricing service may employ methodologies that utilize actual market transactions, broker-dealer supplied valuations, or other formula-driven valuation techniques. These techniques generally consider such factors as yields or prices of bonds of comparable quality, type of issue, coupon, maturity, ratings, and general market conditions. Securities for which prices are not available from an independent pricing service but where an active market exists are valued using market quotations obtained from one or more dealers that make markets in the securities or from a widely-used quotation system. When market quotations are not readily available, securities are valued at fair value as determined in good faith by procedures established and approved by the fund's board of directors. Some of the factors which may be considered by the board of directors in determining fair value are fundamental analytical data relating to the investment; the nature and duration of any restrictions on disposition; trading in similar securities of the same issuer or comparable companies; information from broker-dealers; and an evaluation of the forces that influence the market in which the security is purchased or sold. If events occur that materially affect the value of securities between the close of trading in those securities and the close of regular trading on the New York Stock Exchange, the securities will be valued at fair value. Debt obligations with 60 days or less remaining until maturity may be valued at their amortized cost, which approximates market value. Security valuations are performed once a week and at the end of each month.
	As of February 28, 2006, the fund had no fair valued securities.

Notes to Financial STATEMENTScontinued

Security Transactions and Investment Income

For financial statement purposes, the fund records security transactions on the trade date of the security purchase or sale. Dividend income is recorded on the ex-dividend date. Interest income, including accretion of bond discounts and amortization of premiums, is recorded on an accrual basis. Security gains and losses are determined on the basis of identified cost, which is the same basis used for federal income tax purposes.

Inverse Floaters

As part of its investment strategy, the fund may invest in certain securities for which the potential income return is inversely related to changes in a floating interest rate ("inverse floaters"). In general, income on inverse floaters will decrease when short-term interest rates increase and increase when short-term interest rates decrease. Inverse floaters may be characterized as derivative securities and may subject the fund to the risks of reduced or eliminated interest payments and losses of invested principal. In addition, inverse floaters have the effect of providing investment leverage and as a result, the market value of such securities will generally be more volatile than that of fixed-rate, tax-exempt securities. To the extent the fund invests in inverse floaters, the net asset value of the fund's shares may be more volatile than if the fund did not invest in such securities. As of February 28, 2006, the fund had no outstanding inve stments in inverse floaters.

Futures Transactions

In order to protect against changes in interest rates, the fund may buy and sell interest rate futures contracts. Upon entering into a futures contract, the fund is required to deposit cash or pledge U.S. government securities in an amount equal to 5% of the purchase price indicated in the futures contract (initial margin). Subsequent payments, which are dependent on the daily fluctuations in the value of the underlying security or securities, are made or received by the fund each day (daily variation margin) and recorded as unrealized gains (losses) until the contract is closed. When the contract is closed, the fund records a realized gain (loss) equal to the difference between the proceeds from (or cost of) the closing transaction and the fund's basis in the contract.

Risks of entering into futures contracts, in general, include the possibility that there will not be a perfect price correlation between the futures contracts and the underlying securities. Second, it is possible that a lack of liquidity for futures contracts could exist in the secondary market, resulting in an inability to close a futures position prior to its maturity date. Third, the purchase of a futures contract involves the risk that the fund could lose more than the original margin deposit required to initiate a futures transaction. These contracts involve market risk in excess of the amount reflected in the fund's statement of assets and liabilities. Unrealized gains (losses) on outstanding positions in futures contracts held at the close of the period will be recognized as capital gains (losses) for federal income tax purposes. As of February 28, 2006, the fund had no outstanding futures contracts.

Securities Purchased on a When-Issued Basis

Delivery and payment for securities that have been purchased by the fund on a when-issued or forward-commitment basis can take place a month or more after the transaction date. Such securities do not earn interest, are subject to market fluctuation, and may increase or decrease in value prior to their delivery. The fund segregates assets with a market value equal to or greater than the amount of its purchase commitments. The purchase of securities on a when-issued or forward-commitment basis may increase the volatility of the fund's net asset value if the fund makes such purchases while remaining substantially fully invested. As of February 28, 2006, the fund had no outstanding when-issued or forward-commitment securities.

Taxes

Federal

The fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and not be subject to federal income tax. Therefore, no income tax provision is required. The fund also intends to distribute its taxable net investment income and realized gains, if any, to avoid the payment of any federal excise taxes.

Net investment income and net realized gains and losses may differ for financial statement and tax purposes primarily because of market discount amortization. The character of distributions made during the fiscal period from net investment income or net realized gains may differ from its ultimate characterization for federal income tax purposes. In addition, due to the timing of dividend distributions, the fiscal period in which amounts are distributed may differ from the period that the income or realized gains or losses were recorded by the fund.

The tax character of common and preferred share distributions paid during the six-month period ended February 28, 2006 (estimated), the seven-month fiscal period ended August 31, 2005, and the fiscal year ended January 31, 2005, were as follows:

	2/28/06		8/31/05		1/31/05
Distributions paid from:
Tax-exempt income	$	1,949,003	$	2,509,104	$	3,902,860
Ordinary income		206,425		28,439		40,845
Short-term capital gains		49,098		8,860		513,972
	$	2,204,526	$	2,546,403	$	4,457,677

At August 31, 2005, the components of accumulated earnings on a tax basis were as follows:

Undistributed tax-exempt income	$	344,534
Undistributed ordinary income		219,798
Accumulated capital losses		(37,339	)
Unrealized appreciation		6,077,979
Accumulated earnings	$	6,604,972

State

Minnesota taxable net income is generally based on federal taxable income. The portion of tax-exempt dividends paid by the fund that is derived from interest on Minnesota municipal bonds will be excluded from Minnesota taxable net income of individuals, estates, and trusts, provided that the portion of the tax-exempt dividends paid from these obligations represents 95% or more of the exempt-interest dividends paid by the fund. The remaining portion of these dividends, and dividends that are not exempt-interest dividends or capital gains distributions, will be included in the Minnesota taxable net income of individuals, estates, and trusts, except for dividends directly attributable to interest on obligations of the U.S. government, its territories and possessions.

Distributions to Shareholders

Distributions from net investment income are made monthly for common shareholders and weekly for preferred shareholders. Common share distributions are recorded as of the close of business on the ex-dividend date and preferred share dividends are accrued daily. Net realized gains distributions, if any, will be made at least annually. Distributions are payable in cash or, for common shareholders pursuant to the fund's dividend reinvestment plan, reinvested in additional common shares of the fund. Under the dividend reinvestment plan, common shares will be purchased in the open market.

Notes to Financial STATEMENTScontinued

	Repurchase Agreements
	For repurchase agreements entered into with certain broker-dealers, the fund, along with other affiliated registered investment companies, may transfer uninvested cash balances into a joint trading account, the daily aggregate balance of which is invested in repurchase agreements secured by U.S. government or agency obligations. Securities pledged as collateral for all individual and joint repurchase agreements are held by the fund's custodian bank until maturity of the repurchase agreement. All agreements require that the daily market value of the collateral be in excess of the repurchase amount, including accrued interest, to protect the fund in the event of a default. As of February 28, 2006, the fund had no outstanding repurchase agreements.
	Deferred Compensation Plan
	Under a Deferred Compensation Plan (the "Plan"), non-interested directors of the First American Fund family may participate and elect to defer receipt of their annual compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of selected open-end First American Funds as designated by the board of directors. All amounts in the Plan are 100% vested and accounts under the Plan are obligations of the fund. Deferred amounts remain in the fund until distributed in accordance with the Plan.
	Use of Estimates in the Preparation of Financial Statements
	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 amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the results of operations during the fiscal period. Actual results could differ from these estimates.
	Reclassifications
	Certain amounts in the January 31, 2005, financial statements have been reclassified to conform to the current presentation.
(3) Remarketed Preferred Shares	As of February 28, 2006, the fund had 1,244 remarketed preferred shares (622 shares in class "M" and 622 shares in class "W") (RP®) outstanding with a liquidation preference of $25,000 per share. The dividend rate on the RP® is adjusted every seven days (on Mondays for class "M" and on Wednesdays for class "W"), as determined by the remarketing agent. On February 28, 2006, the dividend rates were 2.90% and 3.00% for class "M" and "W," respectively.
	RP® is a registered trademark of Merrill Lynch & Company ("Merrill Lynch").
(4) Investment Security Transactions	Cost of purchases and proceeds from sales of securities other than temporary investments in short-term securities for the six-month period ended February 28, 2006, aggregated $10,541,179 and $19,386,049, respectively.
(5) Expenses	Investment Advisory Fees
	Pursuant to an investment advisory agreement (the "Agreement"), USBAM, a subsidiary of U.S. Bank National Association ("U.S. Bank"), manages the fund's assets and furnishes related office facilities, equipment, research, and personnel. The Agreement provides USBAM with a monthly investment advisory fee in an amount equal to an annualized rate of 0.35% of the fund's average weekly net assets including preferred shares. For its fee, USBAM provides investment advice and, in general, conducts the management and investment activities of the fund.

	The fund may invest in related money market funds that are series of First American Funds, Inc. ("FAF"), subject to certain limitations. In order to avoid the payment of duplicative investment advisory fees to USBAM, which acts as the investment advisor to both the fund and the related money market funds, USBAM will reimburse the fund an amount equal to the investment advisory fee received from the related money market funds that is attributable to the assets of the fund. For financial statement purposes, this reimbursement is recorded as investment income.
	Administrative Fees
	USBAM serves as the fund's administrator pursuant to an administration agreement between USBAM and the fund. Under this agreement, USBAM receives a monthly administrative fee in an amount equal to an annualized rate of 0.20% of the fund's average weekly net assets including preferred shares. For its fee, USBAM provides numerous services to the fund including, but not limited to, handling the general business affairs, financial and regulatory reporting, and various other services.
	Remarketing Agent Fees
	The fund has entered into a remarketing agreement with Merrill Lynch (the "Remarketing Agent"). The remarketing agreement provides the Remarketing Agent with a monthly fee in an amount equal to an annualized rate of 0.25% of the fund's average amount of RP® outstanding. For its fee, the Remarketing Agent will remarket shares of RP® tendered to it on behalf of shareholders and will determine the applicable dividend rate for each seven-day dividend period.
	Custodian Fees
	U.S. Bank serves as the fund's custodian pursuant to a custodian agreement with the fund. The custodian fee charged to the fund is equal to an annual rate of 0.005% of average weekly net assets including preferred shares. These fees are computed weekly and paid monthly.
	Under this agreement, interest earned on uninvested cash balances is used to reduce a portion of the fund's custodian expenses. These credits, if any, are disclosed as "Indirect payments from the custodian" in the Statement of Operations. Conversely, the custodian charges a fee for any cash overdrafts incurred, which will increase the fund's custodian expenses. For the six-month period ended February 28, 2006, custodian fees were increased by $153 as a result of overdrafts and reduced by $11 as a result of interest earned.
	Other Fees and Expenses
	In addition to the investment advisory, administrative, remarketing agent, and custodian fees, the fund is responsible for paying most other operating expenses, including: legal, auditing, and accounting services, postage and printing of shareholder reports, transfer agent fees and expenses, listing fees, outside directors' fees and expenses, insurance, interest, taxes, and other miscellaneous expenses.
	For the six-month period ended February 28, 2006, legal fees and expenses were paid to a law firm of which an Assistant Secretary of the Fund is a partner.
(6) Capital Loss Carryover	For federal income tax purposes, the fund had a capital loss carryover at August 31, 2005, which, if not offset by subsequent capital gains, will expire on the fund's fiscal year-end as indicated below.
