AMERICAN MUNICIPAL INCOME PORTFOLIO
FUND OBJECTIVE
High current income exempt from regular federal income tax, consistent with
preservation of capital. The fund's income may be subject to state or local tax
and the federal alternative minimum tax. Investors should consult their tax
advisors. As with other investment companies, there can be no assurance this
fund will achieve its objective.
PRIMARY INVESTMENTS
A diverse range of municipal securities rated investment-grade or of comparable
quality when purchased. These securities may include municipal-derivative
securities, such as inverse floating-rate and inverse interest-only municipal
securities, which may be more volatile than traditional municipal securities in
certain market conditions.

</TABLE>
Average annual total returns are through January 31,1999, and are based on the
change in net asset value (NAV). They reflect the reinvestment of distributions
but do not reflect sales charges. NAV-based performance is used to measure
investment management results.
Average annual total returns based on the change in market price for the
one-year, five-year and since-inception periods ended January 31, 1999, were
10.07%, 5.66% and 5.11%, respectively. These returns assume reinvestment of all
distributions and reflect sales charges on those distributions described in the
fund's dividend reinvestment plan, but not on initial purchases.
PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THIS INVESTMENT. NEITHER SAFETY OF
PRINCIPAL NOR STABILITY OF INCOME IS GUARANTEED. Past performance does not
guarantee future results. The investment return and principal value of an
investment will fluctuate so that fund shares, when sold, may be worth more or
less than their original cost. Closed-end funds, such as this fund, often trade
at discounts to net asset value. Therefore, you may be unable to realize the
full net asset value of your shares when you sell.
The Lipper General Municipal Bond Funds: Leveraged Average represents the
average annual total return, with distributions reinvested, of leveraged
perpetual and term-trust national closed-end municipal funds as characterized by
Lipper Inc. The Lehman Brothers Municipal Long Bond Index is comprised of
municipal bonds with more than 22 years to maturity and an average credit
quality of AA. The index is unmanaged and does not include any fees or expenses
in its total-return figures.
The since-inception numbers for the Lipper average and Lehman index are
calculated from the month end following the fund's inception through January 31,
1999.

AMERICAN MUNICIPAL INCOME PORTFOLIO PROVIDED A NET ASSET VALUE TOTAL RETURN OF
7.62%* FOR THE YEAR ENDED JANUARY 31, 1999. The fund's market price return was
10.07% over the same period. This compares to a 6.81% total return for the
fund's benchmark, the Lehman Brothers Municipal Long Bond Index. Over the same
period, the Lipper General Municipal Bond Funds: Leveraged Average gained 6.47%.
THE PORTFOLIO IS POSITIONED TO BENEFIT MORE FROM STABLE OR DECLINING
INTERMEDIATE- AND LONG-TERM MUNICIPAL INTEREST RATES THAN FROM SIGNIFICANTLY
RISING RATES. If growth continues to increase and economic indicators stay
strong, the uncertainty for the future of interest rates increases. If rates
rise, the portfolio's value will decrease more than if it was positioned
differently.
* ALL RETURNS ASSUME REINVESTMENT OF ALL DISTRIBUTIONS AND DO NOT REFLECT SALES
CHARGES, EXCEPT THE FUND'S TOTAL RETURN BASED ON MARKET PRICE, WHICH DOES
REFLECT SALES CHARGES ON THOSE DISTRIBUTIONS DESCRIBED IN THE FUND'S DIVIDEND
REINVESTMENT PLAN, BUT NOT ON INITIAL PURCHASES. PAST PERFORMANCE DOES NOT
GUARANTEE FUTURE RESULTS. THE INVESTMENT RETURN AND PRINCIPAL VALUE OF AN
INVESTMENT WILL FLUCTUATE SO THAT FUND SHARES, WHEN SOLD, MAY BE WORTH MORE OR
LESS THAN THEIR ORIGINAL COST.

FUND OVERVIEW CONTINUED

THROUGH EARLY FALL, THE GENERAL LEVEL OF INTEREST RATES MOVED DOWN DUE TO
SPREADING GLOBAL FINANCIAL CONCERNS AND THE RESULTING DEMAND FOR U.S. TREASURY
SECURITIES AS A SAFE HAVEN. Simultaneously, the supply of municipal bonds grew
as the robust domestic economy and increased tax revenues allowed a growing
number of new municipal projects to move ahead. By late fall, the increased pace
of economic growth on the domestic front outweighed international concerns and
interest rates began to rise slightly.
REFUNDINGS CONTRIBUTED TO THE INCREASED SUPPLY OF MUNICIPAL BONDS. Municipal
issuers have taken advantage of the lower rates to refund older, higher-yielding
securities, resulting in refundings currently being up more than 100% compared
to last year. Issuance for 1998 reached a high second only to 1993. At the same
time, there seems

FUND OVERVIEW CONTINUED

to be only a minimal increase in demand for municipal bonds due largely to the
ongoing strong performance of the stock market. The decreasing demand for
Treasuries due to the easing of international concerns, bolstered municipals'
outperformance in the latter part of the year.
THE YEAR WAS ONE OF EXTRAORDINARY CONTRASTS IN THE ECONOMY AND FINANCIAL
MARKETS. Real economic growth was measured at nearly 4%; 1998 saw another 25%+
return on the S&P 500 stock index; interest rates fell by nearly a full
percentage point all along the yield curve. And yet, closer scrutiny of the data
reveals a number of negative trends as well: a ballooning trade deficit and
declining manufacturing sector driven by the sharp dip in U.S. exports; outright
losses for many sectors of the stock market; and dramatic widening of credit
spreads in the bond market, especially for corporate and mortgage-backed
securities.
WE HAVE MAINTAINED AN EFFECTIVE DURATION LONGER THAN THE BENCHMARK IN ORDER TO
MAINTAIN THE FUND'S INCOME. While our effective duration has decreased somewhat
over the year, we are still beyond our benchmark and the newly acquired holdings
in unaffiliated closed-end investment companies have increased income. This long
duration, coupled with the fund's leverage from preferred stock could have a
negative impact on the fund's net asset value during a rising interest rate
environment.
WE CONTINUE TO FOCUS ON QUALITY, AND HAVE ALSO SELECTIVELY ADDED HIGHER YIELDING
SECURITIES. Yield spreads on nonrated issues remain attractive and our team of
analysts are researching these additional opportunities.
Thank you for your investment in American Municipal Income Portfolio. We remain
committed to providing you with quality service and look forward to helping you
achieve your investment goals.

FUND OVERVIEW CONTINUED
PREFERRED STOCK
The preferred stock issued by XAA pays dividends at a specified rate and has
preference over common stock in the payments of dividends and the liquidation of
assets. Rates paid on preferred stock are reset every seven days and are based
on short-term, tax-exempt interest rates. Preferred shareholders accept these
short-term rates in exchange for low credit risk (shares of preferred stock are
rated AAA by Moody's and S&P) and high liquidity (shares of preferred stock
trade at par and are remarketed every seven days). The proceeds from the sale of
preferred stock are invested at intermediate- and long-term tax-exempt rates.
Because these intermediate- and long-term rates are normally higher than the
short-term rates paid on preferred stock, common shareholders benefit by
receiving higher dividends and/or an increase to the dividend reserve. However,
the risk of having preferred stock is that if short-term rates rise higher than
intermediate- and long-term rates, creating an inverted yield curve, common
shareholders may receive a lower rate of return than if their fund did not have
any preferred stock outstanding. This type of economic environment is unusual
and historically has been short term in nature. Investors should also be aware
that the issuance of preferred stock results in the leveraging of common stock,
which increases the volatility of both the net asset value of the fund and the
market value of shares of common stock.

(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 in a diverse range of municipal securities rated
investment grade or of comparable quality when purchased. These
securities may include municipal derivative securities, such as
inverse floating rate and inverse interest-only municipal
securities. Fund shares are listed on the New York Stock
Exchange under the symbol XAA.
(2) SUMMARY OF
SIGNIFICANT
ACCOUNTING
POLICIES
............................
INVESTMENTS IN SECURITIES
Portfolio securities for which market quotations are readily
available are valued at current market value. If market
quotations or valuations are not readily available, or if such
quotations or valuations are believed to be inaccurate,
unreliable or not reflective of market value, portfolio
securities are valued according to procedures adopted by the
fund's board of directors in good faith at "fair value", that
is, a price that the fund might reasonably expect to receive for
the security or other asset upon its current sale.
The current market value of certain fixed income securities is
provided by an independent pricing service. Fixed income
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. Short-term securities with
maturities of 60 days or less are valued at amortized cost,
which approximates market value.
Pricing services value domestic equity securities traded on a
securities exchange or Nasdaq at the last reported sale price,
up to the time of valuation. If there are no reported sales of a
security on the valuation date, it is valued at the mean between
the published bid and asked prices reported by the exchange or
Nasdaq. If there are no sales and no published bid and asked
- --------------------------------------------------------------------------------
1999 Annual Report 9 American Municipal Income Portfolio
<PAGE>
NOTES TO FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------
quotations for a security on the valuation date or the security
is not traded on an exchange or Nasdaq, the pricing service may
obtain market quotations directly from broker-dealers.
Securities transactions are accounted for on the date securities
are purchased or sold. Realized gains and losses are calculated
on the identified-cost basis. Dividend income is recognized on
the ex-dividend date and interest income, including amortization
of bond discount and premium, is recorded on an accrual basis.
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 January 31, 1999,
the fund had entered into outstanding when-issued or forward
commitments of $997,042.
FEDERAL TAXES
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 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
- --------------------------------------------------------------------------------
1999 Annual Report 10 American Municipal Income Portfolio
<PAGE>
NOTES TO FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------
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.
On the statement of assets and liabilities, as a result of
permanent book-to-tax differences, a reclassification adjustment
has been made to decrease undistributed net investment income
and decrease accumulated net realized loss on investments by
$222.
DISTRIBUTIONS TO SHAREHOLDERS
Distributions from net investment income are made monthly for
common shareholders and weekly for preferred shareholders.
Common stock distributions are recorded as of the close of
business on the ex-dividend date and preferred stock 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 shares of the fund's
common stock. Under the plan, common shares will be purchased in
the open market.
USE OF ESTIMATES
The preparation of financial statements in conformity with
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
STOCK
............................
American Municipal Income Portfolio has issued and, as of
January 31, 1999, has outstanding 1,740 shares of remarketed
preferred stock (870 shares in class "T" and 870 shares in class
"TH") (RP) with a liquidation preference of $25,000 per share.
The dividend rate on the RP is adjusted every seven days (on
- --------------------------------------------------------------------------------
1999 Annual Report 11 American Municipal Income Portfolio
<PAGE>
NOTES TO FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------
Tuesdays for class "T" and on Thursdays for class "TH"), as
determined by the remarketing agent. On January 31, 1999, the
dividend rate was 2.75% for both class "T" and "TH".
RP is a registered trademark of Merrill Lynch & Company.
(4) INVESTMENT
SECURITY
TRANSACTIONS
............................
Cost of purchases and proceeds from sales of securities, other
than temporary investments in short-term securities, for the
year ended January 31, 1999, aggregated $25,384,527 and
$24,173,844, respectively.
(5) EXPENSES
............................
INVESTMENT MANAGEMENT AND ADMINISTRATIVE FEES
On August 10, 1998, the fund entered into an investment advisory
agreement with U.S. Bank National Association (U.S. Bank),
acting through its division, First American Asset Management.
Prior thereto, Piper Capital Management Incorporated, which was
acquired by U.S. Bancorp on May 1, 1998, had served as the
fund's advisor. U.S. Bank also serves as the fund's
administrator under an administration agreement effective May 1,
1998. Prior thereto, Piper Capital provided services under an
administration agreement through April 30, 1998.
The investment advisory agreement provides the advisor with a
monthly investment management fee equal to an annual rate of
0.35% of the fund's average weekly net assets (computed by
subtracting liabilities, which exclude preferred stock, from the
value of the total assets of the fund). For its fee, the advisor
provides investment advice and conducts the management and
investment activities of the fund.
The administration agreement provides the administrator with a
monthly fee in an amount equal to an annual rate of 0.15% of the
fund's average weekly net assets (computed by subtracting
liabilities, which exclude preferred stock, from the value of
the total assets of the fund). For its fee, the administrator
provides reporting, regulatory and record-keeping services for
the fund.
- --------------------------------------------------------------------------------

<PAGE>
NOTES TO FINANCIAL STATEMENTS (continued)
- --------------------------------------------------------------------------------
REMARKETING AGENT FEE
The fund has entered into a remarketing agent agreement with
Merrill Lynch, Pierce, Fenner & Smith (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.
OTHER FEES AND EXPENSES
In addition to the investment management, administrative and
remarketing agent fees, the fund is responsible for paying most
other operating expenses including: outside directors' fees and
expenses; custodian fees; registration fees; printing and
shareholder reports; transfer agent fees and expenses; legal,
auditing and accounting services; insurance; interest; taxes and
other miscellaneous expenses.
Expenses paid indirectly represent a reduction of custodian fees
for earnings on miscellaneous cash balances maintained by the
fund.
(6) CAPITAL LOSS
CARRYOVER
............................
For federal income tax purposes, the fund had capital loss
carryovers at January 31, 1999, which, if not offset by
subsequent capital gains, will expire on the fund's fiscal
year-ends as indicated below. It is unlikely the board of
directors will authorize a distribution of any net realized
capital gains until the available capital loss carryovers have
been offset or expire.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------
THE BOARD OF DIRECTORS AND SHAREHOLDERS
AMERICAN MUNICIPAL INCOME PORTFOLIO INC.:
We have audited the accompanying statement of assets and liabilities, including
the schedule of investments in securities, of American Municipal Income
Portfolio Inc. as of January 31, 1999, the related statement of operations for
the year then ended, the statements of changes in net assets for each of the
years in the two-year period ended January 31, 1999 and the financial highlights
for each of the years in the five-year period ended January 31, 1999. These
financial statements and the financial highlights are the responsibility of the
fund's management. Our responsibility is to express an opinion on these
financial statements and the financial highlights based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Investment securities held in custody are confirmed to us by the
custodian. As to securities purchased but not received, we request confirmations
from brokers and, where replies are not received, we carry out other appropriate
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.
In our opinion, the financial statements and the financial highlights referred
to above present fairly, in all material respects, the financial position of
American Municipal Income Portfolio Inc. as of January 31, 1999, and the results
of its operations, the changes in its net assets and the financial highlights
for the periods stated in the first paragraph above, in conformity with
generally accepted accounting principles.

INVESTMENT POLICY CHANGE
The Board of Directors of XAA has recently approved a
modification of the investment policies of the fund. The fund
may now invest up to 5% of its total assets in the securities of
unaffiliated closed-end investment companies that invest
primarily in tax-exempt obligations.
CHANGE OF ACCOUNTANTS
On September 9, 1998, the fund's board of directors, upon the
recommendation of the audit committee, appointed Ernst & Young
LLP the independent accountants for the fund for the fiscal year
ending January 31, 2000, and dismissed KPMG Peat Marwick LLP
("KPMG"). KPMG's reports on the fund's financial statements for
the past two years have not contained an adverse opinion or a
disclaimer of opinion, and have not

been qualified as to uncertainty, audit scope, or accounting
principles. In addition, there have not been any disagreements
with KPMG during the fund's two most recent fiscal years on any
matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure which, if
not resolved to the satisfaction of KPMG, would have caused it
to make a reference to the subject matter of the disagreement in
connection with its reports.
TERMS AND CONDITIONS OF THE DIVIDEND REINVESTMENT PLAN
As a shareholder, you may choose to participate in the Dividend
Reinvestment Plan. It's a convenient and economical way to buy
additional shares of the fund by automatically reinvesting
dividends and capital gains. The plan is administered by
Investors Fiduciary Trust Company (IFTC), the plan agent.
ELIGIBILITY/PARTICIPATION
You may join the plan at any time. Reinvestment of distributions
will begin with the next distribution paid, provided your
request is received at least 10 days before the record date for
that distribution.
If your shares are in certificate form, you may join the plan
directly and have your distributions reinvested in additional
shares of the fund. To enroll in this plan, call IFTC at
1-800-543-1627. If your shares are registered in your brokerage
firm's name or another name, ask the holder of your shares how
you may participate.
Banks, brokers or nominees, on behalf of their beneficial owners
who wish to reinvest dividend and capital gains distributions,
may participate in the plan by informing IFTC at least 10 days
before the next dividend and/or capital gains distribution.

PLAN ADMINISTRATION
Beginning no more than five business days before the dividend
payment date, IFTC will buy shares of the fund on the New York
Stock Exchange (NYSE) or elsewhere on the open market.
The fund will not issue any new shares in connection with the
plan. All reinvestments will be at a market price plus a pro
rata share of any brokerage commissions, which may be more or
less than the fund's net asset value per share. The number of
shares allocated to you is determined by dividing the amount of
the dividend or distribution by the applicable price per share.
There is no direct charge for reinvestment of dividends and
capital gains, since IFTC fees are paid for by the fund.
However, each participant pays a pro rata portion of the
brokerage commissions. Brokerage charges are expected to be
lower than those for individual transactions because shares are
purchased for all participants in blocks. As long as you
continue to participate in the plan, distributions paid on the
shares in your account will be reinvested.
IFTC maintains accounts for plan participants holding shares in
certificate form and will furnish written confirmation of all
transactions, including information you need for tax records.
Reinvested shares in your account will be held by IFTC in
noncertificated form in your name.
TAX INFORMATION
Distributions invested in additional shares of the fund are
subject to income tax, to the same extent they would be if
received in cash. Shareholders, as required by the Internal
Revenue Service, will receive Form 1099 regarding the federal
tax status of the prior year's distributions.
PLAN WITHDRAWAL
If you hold your shares in certificate form, you may terminate
your participation in the plan at any time by giving written
- --------------------------------------------------------------------------------

SHAREHOLDER UPDATE (continued)
- --------------------------------------------------------------------------------
notice to IFTC. If your shares are registered in your brokerage
firm's name, you may terminate your participation via verbal or
written instructions to your investment professional. Written
instructions should include your name and address as they appear
on the certificate or account.
If notice is received at least 10 days before the record date,
all future distributions will be paid directly to the
shareholder of record.
If your shares are issued in certificate form and you
discontinue your participation in the plan, you (or your
nominee) will receive an additional certificate for all full
shares and a check for any fractional shares in your account.
PLAN AMENDMENT/TERMINATION
The fund reserves the right to amend or terminate the plan.
Should the plan be amended or terminated, participants will be
notified in writing at least 90 days before the record date for
such dividend or distribution. The plan may also be amended or
terminated by IFTC with at least 90 days written notice to
participants in the plan.
Any questions about the plan should be directed to your
investment professional or to Investors Fiduciary Trust Company,
P.O. Box 419432, Kansas City, Missouri 64141, 1-800-543-1627.
