Notes to Financial STATEMENTS(Unaudited)

(1	) Organization	American Municipal Income Portfolio Inc. (the "Fund") is registered under the Investment Company Act of 1940 (as amended) as a diversified, closed-end management investment company. The Fund invests primarily in a diverse range of 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. Additional information regarding recent investment policy changes can be found in the shareholder update section of the report. Municipal sec urities in which the Fund invests may include municipal derivative securities, such as inverse floating rate and inverse interest-only municipal securities. The Fund'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 sentence, and may do so in the future, the Fund did not make any such investments during the six months ended July 31, 2004. Fund shares are listed on the New York Stock Exchange under the symbol XAA.
(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. Investments in equity securities that are traded on a national securities exchange are stated at the last quoted sales price if readily available for such securities on each business day. For

2004 Semiannual Report

American Municipal Income Portfolio

securities traded on NASDAQ national market system, the Fund utilizes the NASDAQ Official Closing Price which compares the last trade to the bid/ask price of a security. If the last trade is within the bid/ask range, then that price will be the closing price. If the last trade is outside the bid/ask range, and falls above the ask, the ask price will be the closing price. If the last trade is below the bid, the bid will be the closing price. Other equity securities traded in the over-the-counter market and listed equity securities for which no sale was reported on that date are stated at the last quoted bid price. 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 securities are purchased and sold. If events occur that mat erially affect the value of securities (including non-U.S. 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. As of

2004 Semiannual Report

American Municipal Income Portfolio

7

Notes to Financial STATEMENTS(Unaudited) continued

July 31, 2004, the Fund had no fair valued securities. 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.

Security Transactions and Investment Income

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 investments in these securities 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 values of such securities will generally be more volatile than those 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 securi ties. As of July 31, 2004, the Fund had no outstanding investments in inverse floaters.

Futures Transactions

To gain exposure to or protect itself from changes in the market, the Fund may buy and sell interest rate futures

2004 Semiannual Report

American Municipal Income Portfolio

8

contracts. Risks of entering into futures contracts and related options include the possibility there may be an illiquid market and that a change in the value of the contract or option may not correlate with changes in the value of the underlying securities.

Upon entering into a futures contract, the Fund is required to deposit, in segregated accounts with its custodian, either cash or securities in an amount (initial margin) equal to a certain percentage of the contract value. Subsequent payments (variation margin) are made or received by the Fund each day. The variation margin payments are equal to the daily changes in the contract value and are recorded as unrealized gains and losses. The Fund recognizes a realized gain or loss when the contract is closed or expires. As of July 31, 2004, 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. During this period, 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, with its custodian, assets with a market value equal to 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 July 31, 2004, the Fund had entered into outstanding when-issued or forward-commitment securities of $2,514,275.

Federal Taxes

The Fund intends to comply with the requirements of the Internal Revenue Code applicable to regulated investment

Notes to Financial STATEMENTS(Unaudited) continued

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 year 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 year in which amounts are distributed may differ from the year 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 months ended July 31, 2004 (estimated) and the fiscal year ended January 31, 2004, were characterized as follows:

	7/31/04		1/31/04
Distributions paid from:
Tax-exempt income	$	2,903,107	$	5,745,748
Ordinary income		-		60,896
	$	2,903,107	$	5,806,644

At January 31, 2004, the Fund's most recently completed fiscal year-end, the components of accumulated earnings on a tax basis were as follows:

Undistributed tax-exempt income	$	1,336,185
Undistributed ordinary income		8,853
Accumulated capital losses		(562,428	)
Unrealized appreciation		9,351,971
Accumulated earnings	$	10,134,581

2004 Semiannual Report

American Municipal Income Portfolio

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.

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. Provisions for all agreements ensure that the daily market value of the collateral is in excess of the repurchase amount, including accrued interest, to protect the Fund in the event of a default.

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 amounts in the financial statements. Actual results could differ from these estimates.

(3	) Remarketed Preferred Shares	As of July 31, 2004, the Fund had 1,740 remarketed preferred shares (870 shares in class "T" and 870 shares in class "TH") (RP®) outstanding with a liquidation preference of $25,000 per share. The dividend rate on the RP® is adjusted every seven days (on Tuesdays for class "T" and on Thursdays for class "TH"), as determined by the remarketing agent. On July 31, 2004, the dividend rates were 1.00% and 1.03% for class "T" and "TH", 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 months ended July 31, 2004, aggregated $26,528,159 and $29,378,421, respectively.
(5	) Expenses	Investment Management and Administrative 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 management fee in an amount equal to an annualized rate of 0.35% of the Fund's average weekly net assets (computed by subtracting liabilities, which exclude preferred shares, from the value of the total assets of the Fund). For its fee, USBAM provides investment advice and, in general, conducts the management and investment activities of the Fund.
		Pursuant to a co-administration agreement (the "Co-Administration Agreement"), USBAM serves as co-administrator for the Fund (U.S. Bancorp Fund Services, LLC, a subsidiary of U.S. Bancorp is also co-administrator but currently has no functional responsibilities related the Fund) and provides

2004 Semiannual Report

12

administrative services, including legal and shareholder services, to the Fund. Under this Co-Administration 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 (computed by subtracting liabilities, which exclude preferred shares, from the value of the total assets of the Fund). 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. Separate from the Co-Administration Agreement, USBAM (from its own resources) has retained SEI Investments, Inc. as a sub-administrator to perform, among other services, net asset value calculations.

The Fund may invest in 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 adviser to both the Fund and the related money market funds, USBAM will reimburse the Fund an amount equal to that portion of 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.

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 annual 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 fee for the Fund is equal to an annual rate of 0.015% of average weekly net assets. These fees are computed weekly and paid monthly.
		Other Fees and Expenses
		In addition to the investment management, administrative, custodian, and remarketing agent fees, the Fund is responsible for paying most other operating expenses including: outside directors' fees and expenses, registration fees, printing and shareholder reports, transfer agent fees and expenses, legal, auditing, and accounting services, insurance, interest, taxes, and other miscellaneous expenses.
(6	) Capital Loss Carryover	For federal income tax purposes, the Fund had capital loss carryovers at January 31, 2004, the Fund's most recently completed fiscal year-end, which, if not offset by subsequent capital gains, will expire on the Fund's fiscal year-ends as indicated below.

Capital Loss Carryover		Expiration

	346,227		2009
$	562,428

(7 ) Indemnifications The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

SHAREHOLDER UPDATE

Investment Policy Change

To date, all of the Fund's municipal security investments have been, at the time of purchase, either rated investment grade or, if unrated, determined to be of comparable quality. Effective immediately, the Fund may invest up to 5% of its total assets in municipal securities that are, at the time of purchase, either rated lower than investment grade or, if unrated, determined to be of comparable quality. These securities are commonly referred to as "high yield" securities or "junk bonds." The Fund will not invest in municipal securities that, at the time of purchase, are rated lower than B or are unrated and determined to be of comparable quality. If the rating of a security is reduced or discontinued after purchase, the Fund is not required to sell the security, but it may consider doing so. The Fund's investments in high yield securities (rated and unrated) and investment-grade quality unrated securities will not exceed, in the aggregate, 25% of the Fund's total assets (not including unrated securities that have been pre-refunded with U.S. Government securities and U.S. Government agency securities). All determinations regarding the credit quality of unrated securities are made by USBAM.

High yield securities generally have more volatile prices, carry more risk to principal and may be more susceptible to real or perceived adverse economic conditions than investment grade securities. In addition, the secondary market for high yield securities may be less liquid than for investment grade securities. When the Fund purchases unrated securities, it will depend on USBAM's analysis of credit risk without the assessment of an independent rating organization, such as Moody's Investors Service or Standard & Poor's.
