AMERICAN MUNICIPAL TERM TRUSTS
- -------------------------------------------------------------------------------

PRIMARY INVESTMENTS
High-quality municipal obligations including 
municipal zero-coupon securities.

FUND OBJECTIVE
American Municipal Term Trust (AXT), American Municipal Term Trust II (BXT) and
American Municipal Term Trust III (CXT) are diversified, closed-end management
investment companies. The investment objectives of AXT, BXT and CXT are to
provide high current income exempt from regular federal income tax and to return
$10 per share on or shortly before April 15, 2001; April 15, 2002; and April 15,
2003, respectively - although each fund's termination may be extended up to five
years if necessary to assist the fund in reaching its $10 per share objective.

All total returns are through December 31, 1997, and reflect the reinvestment of
distributions but not sales charges. NAV-based performance is used to measure
investment management results. As noted in earlier shareholder reports, we no
longer compare the funds' NAV performance to a market benchmark. This is because
our primary goal is to meet the funds' investment objectives of providing high
current income exempt from regular federal income tax and returning $10 per
share to investors at the funds' termination dates.

Average annualized total returns based on the change in market price for the
one-year, five-year and since inception periods ended December 31, 1997, were
8.89%, 8.35% and 8.54% for AXT, 12.46%, 8.19% and 8.33% for BXT and 11.93%,
8.16% and 7.73% for CXT.  These returns assume reinvestment of all distributions
and reflect sales charges on those distributions described in the funds'
dividend reinvestment plan, but not on initial purchases.

PLEASE REMEMBER, YOU COULD LOSE MONEY WITH THESE INVESTMENTS. 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 these funds, 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.

DEAR SHAREHOLDERS:

WE ARE PLEASED THAT THE AMERICAN MUNICIPAL TERM TRUSTS (AXT, BXT AND CXT) 
REMAINED ON TARGET TO MEET THEIR INVESTMENT OBJECTIVES OF PROVIDING HIGH 
TAX-EXEMPT INCOME AND RETURNING $10 PER SHARE TO INVESTORS ON OR SHORTLY 
BEFORE THEIR TERMINATION DATES. For the year ended December 31, 1997, the 
funds continued to earn more than their monthly common and preferred stock*** 
dividends and add to their dividend reserves. Since the funds' inceptions, 
the funds have maintained monthly common stock distributions of 5.42 cents, 
5.17 cents and 4.75 cents per share, respectively. In addition, the funds' 
net asset values remain above the $10 per share objective. As of December 31, 
1997, the net asset values for AXT, BXT and CXT were $11.51, $11.60 and 
$11.39, respectively.

DURING THE FUNDS' FISCAL YEAR, MUNICIPAL BOND PRICES WERE VOLATILE; HOWEVER, NO
EVENTS WERE EXTREME ENOUGH TO CAUSE US TO CHANGE OUR STRATEGY FOR THESE TERM
TRUSTS. Economically speaking, the year had a strong start, prompting the
Federal Reserve Board to raise the federal funds rate in March from 5.25% to
5.50%, which caused bond yields to rise and prices to fall. By April, the
economy showed signs of slowing, sending interest rates down and bond prices up,
a trend that reversed again in the third quarter. In the

fourth quarter, the expectation of continued moderate economic growth, low 
inflation and a flight-to-quality resulting from the Asian turmoil fueled a 
U.S. bond market rally. Given the lack of direct foreign demand for municipal 
issues, municipal yields decreased more slowly than Treasury yields. This, 
along with an increase in municipal issues, caused the municipal market to 
underperform its taxable counterpart during the last quarter of the year. 
During 1997, the national supply of municipal issues increased by 20%, 
compared to 1996.

AS THE FUNDS NEAR THEIR TERMINATION DATES, WE CONTINUE TO SELL LONGER MATURITY
BONDS IN FAVOR OF THOSE CLOSER TO THE FUNDS' TERMINATIONS. As shown in the chart
below, the percentage of bonds with maturity or refunded dates*** within a year
of the funds' termination dates continues to increase. We made appropriate
trades as opportunities arose. As interest rates fell during the year and bond
prices increased, restructuring generated capital gains, which were distributed.
Also, restructuring proceeds were reinvested at lower interest rates, decreasing
fund income. Advance refunding*** is responsible for a portion of the increase
in the percentages shown in the chart.

WE EXPECT THAT THE FUNDS' NET ASSET VALUES WILL DECLINE AS THE FUNDS NEAR THEIR
TERMINATION DATES. There are several events that could cause this to occur.  As

these bonds approach, their market prices will converge toward a price that is
at or near their maturity or refunding prices. In addition, as the funds
approach termination, we continue to sell longer maturity bonds in favor of
bonds with shorter maturities and lower coupons*** that come due closer to the
funds' termination dates. Any gains realized as a result of these sales will be
distributed to shareholders, reducing net asset value. If the shorter-maturity
bonds pay insufficient income to maintain our current dividends, the funds'
dividend reserves may be used to pay common and/or preferred dividends. See the
chart below for each fund's current accumulated realized*** gains, unrealized***
appreciation and current dividend reserve. Shareholders also should remember
that the funds are always subject to interest rate risk*** and credit risk,***
which could have an impact on net asset value.

WE ARE OPTIMISTIC ABOUT THE MUNICIPAL MARKET DURING THE COMING MONTHS, AND
AGAIN, WE DON'T ANTICIPATE EVENTS THAT WOULD CAUSE US TO CHANGE THE FUNDS'
INVESTMENT STRATEGY AS THEY MOVE TOWARD TERMINATION. However, we remain watchful
for further negative news about Asian economies or a significant increase in the

(1) ORGANIZATION
 ................................
               American Municipal Term Trust Inc. (AXT), American Municipal Term
               Trust Inc. II (BXT) and American Municipal Term Trust Inc. III
               (CXT) (the funds) are registered under the Investment Company Act
               of 1940 (as amended) as diversified, closed-end management
               investment companies. AXT, BXT and CXT expect to terminate
               operations and distribute all of their net assets to shareholders
               on or shortly before April 15, 2001, April 15, 2002, and April
               15, 2003, respectively, although termination may be extended to a
               date no later than April 15, 2006, April 15, 2007, and April 15,
               2008, respectively. The funds invest primarily in high-quality
               municipal obligations including municipal zero-coupon securities.
               Fund shares are listed on the New York Stock Exchange under the
               symbols AXT, BXT and CXT, respectively.
 
(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
               funds' board of directors in good faith at "fair value", that is,
               a price that the funds 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.

           Notes to Financial Statements (continued)
- --------------------------------------------------------------------------------
 
               Securities transactions are accounted for on the date securities
               are purchased or sold. Realized gains and losses are calculated
               on the identified-cost basis. 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 funds 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 funds segregate, with their custodian, assets
               with a market value equal to the amount of their purchase
               commitments. The purchase of securities on a when-issued or
               forward-commitment basis may increase the volatility of the
               funds' net asset value if the funds make such purchases while
               remaining substantially fully invested. As of December 31, 1997,
               American Municipal Term Trust Inc., American Municipal Term Trust
               Inc. II, and American Municipal Term Trust Inc. III had entered
               into outstanding when-issued or forward commitments of $0,
               $700,263, and $1,000,000, respectively.
 
                  FEDERAL TAXES
               Each fund is treated separately for federal income tax purposes.
               Each 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 funds intend to distribute their
               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 (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
               (losses) were recorded by the funds.
 
               On the statements of assets and liabilities, as a result of
               permanent book-to-tax differences, reclassification adjustments
               have been made as follows:

                  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. Per share common stock distributions of $0.0542, $0.0517,
               and $0.0475 for American Municipal Term Trust Inc., American
               Municipal Term Trust Inc. II, and American Municipal Term Trust
               Inc. III, respectively, were declared in December and are payable
               in January. Net realized gains distributions, if any, will be
               made at least annually. Distributions are payable in cash or, for
               common shareholders pursuant to the funds' dividend reinvestment
               plans, reinvested in additional shares of the funds' common
               stock. Under the plans, 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

               from the value of the total assets of the funds). For its fee,

               the management and investment activity of the funds.
 
               The administration agreement provides the administrator with a
               monthly fee in an amount equal to an annualized rate of 0.15% of
               the funds' average weekly net assets (computed by subtracting
               liabilities, which exclude preferred stock, from the value of the
               total assets of the funds). For its fee, the administrator will
               provide regulatory reporting and record-keeping services for the
               funds.

               monthly fee in an amount equal to an annualized rate of 0.25% of
               the funds' average amount of RP outstanding. For its fee, the
               remarketing agent will remarket shares of RP tendered to it, on
               behalf of shareholders thereof, 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 the

               quarter of 1998, subject to regulatory approval, the approval of
               Piper Jaffray Companies shareholders and the satisfaction of
               customary closing conditions.
 
               U.S. Bancorp is a multi-state bank holding company headquartered
               in Minneapolis, Minnesota with a geographic service area spanning
               17 states. As of December 31, 1997, U.S. Bancorp was the 15th
               largest U.S. commercial bank holding company, with assets of
               nearly $71.3 billion. U.S. Bank National Association ("U.S.
               Bank"), a wholly owned subsidiary of U.S. Bancorp, currently acts
               as the investment advisor to 32 mutual funds (the "First American
               Funds"). As of December 31, 1997, U.S. Bank, acting through its
               First American Asset Management group, managed more than $55
               billion in assets, including approximately $20.5 billion in
               assets of the First American Funds.
 
               Under the Investment Company Act of 1940, as amended (the "1940
               Act"), consummation of the acquisition of Piper Jaffray Companies
               by U.S. Bancorp will result in the assignment and automatic
               termination of the funds' investment advisory agreement with
               Piper Capital Management Incorporated. The 1940 Act requires that
               any new investment advisory agreement for the funds be approved
               by the funds' boards of directors and shareholders.

Independent Auditors' Report
- --------------------------------------------------------------------------------
 
THE BOARD OF DIRECTORS AND SHAREHOLDERS
AMERICAN MUNICIPAL TERM TRUST INC.,
AMERICAN MUNICIPAL TERM TRUST INC. II AND
AMERICAN MUNICIPAL TERM TRUST INC. III:
 
We have audited the accompanying statements of assets and liabilities, including
the schedules of investments in securities, of American Municipal Term Trust
Inc., American Municipal Term Trust Inc. II, and American Municipal Term Trust
Inc. III as of December 31, 1997, and the related statements 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 December 31, 1997, and the financial
highlights for each of the years in the five-year period ended December 31,
1997. These financial statements and the financial highlights are the
responsibility of the funds' 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 Term Trust Inc., American Municipal Term Trust Inc. II and
American Municipal Term Trust Inc. III as of December 31, 1997, and the results
of their operations, the changes in their net assets and the financial
highlights for the periods stated in the first paragraph above, in conformity
with generally accepted accounting principles.

                  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 each share's 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, just as 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
               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 question 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.

GLOSSARY OF TERMS***
- --------------------------------------------------------------------------------
Advance refunding
The sale of new bonds (a refunding issue) in advance, usually by some years, of
the first call date of the old bonds (issue to be refunded). The refunding issue
would normally have a lower rate than the issue to be refunded and the proceeds
from the sale of the refunding issue would be invested, usually in government
securities, until the higher-rate bonds become callable. 

Coupon
The interest rate on a bond that the issuer promises to pay to the holder until 
the bond matures or resets its rate. It is expressed as an annual percentage of
face value.

Credit risk
The risk that a bond issuer will not make timely principal and interest payments
and a loss to the investor will result.

Interest rate risk
The risk that after an investor purchases a bond, interest rates will rise and
the price of the bond will go down.

Preferred stock
The preferred stock issued by AXT, BXT and CXT 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.

Refunded date

The specific date when a bond is redeemed before maturity.

Realized gains
Profits earned by a fund from the sale of a security at a market price that is
higher than its cost basis.

Unrealized appreciation
A bond is said to be trading at unrealized gains when its current market price
is higher than its cost basis.
