An Overview of the Funds


What are the funds' investment objectives?
These funds seek high current income and investment returns that are exempt from
federal income tax and taxes imposed by New York (both city and state), Florida
or Arizona.

What are the funds' primary investment strategies and principal risks?
The fund managers invest most of the funds' assets in debt securities issued by cities, counties and
other municipalities, and U.S. territories. Each of the funds invests in different types of these
municipal debt securities and has different risks. The following chart shows the differences among
the funds' primary investments and principal risks. It is designed to help you compare these funds
with other mutual funds. A more detailed description about the funds' investment strategies and
risks begins on page 7.

                                                                          Interest rate risk

Arizona Intermediate-Term Municipal Quality debt securities that          Arizona economic risk
                                    mature in five to 10 years            Credit risk
                                                                          Interest rate risk

As with all funds, your shares may be worth more or less at any given time than the price you paid.
As a result, it is possible to lose money by investing in the funds.

Who may want to invest in the funds?
The funds may be a good investment if you are
o  a New York, Florida or Arizona resident or taxpayer
o  seeking current tax-free income
o  comfortable with risk based on New York's, Florida's or Arizona's economy
o  comfortable with the funds' other investment risks
o  seeking diversification by investing in a fixed-income mutual fund

Who may not want to invest in the funds?
The funds may not be a good investment if you are
o  investing in an IRA or other tax-advantaged retirement plan
o  investing for long-term growth
o  looking for the added security of FDIC insurance

Callout
Debt securities include fixed-income investments such as notes, bonds, commercial paper and
debentures.

An investment in the funds is not a bank deposit, and it is not insured or guaranteed by the Federal
Deposit Insurance Corporation (FDIC) or any other government agency. Although the money market funds
seek to preserve the value of your investment at $1.00 per share, it is possible to lose money by
investing in them.

Objectives, Strategies and Risks


New York Municipal Money Market Fund

What are the fund's investment objectives?
New York Municipal Money Market seeks safety of principal and high current income that is exempt
from federal income tax and seeks to be exempt from the New York tax.

How does the fund pursue its investment objectives?
The fund managers buy cash-equivalent, high-quality debt securities with interest payments exempt
from federal, New York state and New York City income taxes. Cities, counties and other
municipalities in New York and U.S. territories (such as Puerto Rico) usually issue these securities
for public projects, such as schools and roads.
The fund managers also may buy cash-equivalent, high-quality debt securities with interest payments
exempt from federal, New York state and New York City income taxes, but not exempt from the federal
alternative minimum tax. Cities, counties and other municipalities in New York and U.S. territories
(such as Puerto Rico) usually issue these securities (called private activity bonds) to fund
for-profit private projects, such as hospitals and athletic stadiums.

What are the principal risks of investing in the funds?
Because cash-equivalent securities are among the safest securities available, the interest they pay
is among the lowest for income-paying securities. Accordingly, the yield on this fund will likely be
lower than funds that invest in longer-term or lower-quality securities.
Because the fund invests primarily in New York municipal securities, it will be sensitive to events
that affect New York's economy. New York Municipal Money Market may have a higher level of risk than
funds that invest in a larger universe of securities.

Callout
Income from the fund may be subject to the alternative minimum tax. For more information, see Taxes
in this Prospectus.


A high-quality debt security is one that has been determined to be in the top two credit quality
categories. This can be established in a number of ways. For example, independent rating agencies
may rate the security in their higher rating categories. The fund's advisor also can analyze an
unrated security to determine if its credit quality is high enough for investment. The details of
the fund's credit quality standards are described in the Statement of Additional Information.









Florida Municipal Money Market Fund

What are the fund's investment objectives?
Florida Municipal Money Market seeks safety of principal and high current income that is exempt from
federal income tax and seeks to be exempt from the Florida intangible personal property tax.

How does the fund pursue its investment objectives?
The fund managers buy cash-equivalent, high-quality debt securities with interest payments exempt
from federal income tax and the Florida intangible personal property tax. Cities, counties and other
municipalities in Florida usually issue these securities for public projects, such as schools and
roads.
The fund managers also may buy cash-equivalent, high-quality debt securities with interest payments
exempt from federal income tax and from the Florida intangible personal property tax, but not exempt
from the federal alternative minimum tax. Cities, counties and other municipalities in Florida
usually issue these securities (called private activity bonds) to fund for-profit private projects,
such as hospitals and athletic stadiums.
Additional information about the fund's investments is available in its annual and semiannual
reports. In these reports you will find a discussion of the market conditions and investment
strategies that significantly affected the fund's performance during the most recent fiscal period.
You may get these reports at no cost by calling us.

What are the principal risks of investing in the fund?
Because cash-equivalent securities are among the safest securities available, the interest they pay
is among the lowest for income-paying securities. Accordingly, the yield on this fund will likely be
lower than funds that invest in longer-term or lower-quality securities.
Because the fund invests primarily in Florida municipal securities, it will be sensitive to events
that affect Florida's economy. Florida Municipal Money Market may have a higher level of risk than
funds that invest in a larger universe of securities.

Florida Intermediate-Term Municipal Fund

What are the fund's investment objectives?
Florida Intermediate-Term Municipal seeks safety of principal and high current income that is exempt
from federal income tax and seeks to be exempt from the Florida intangible personal property tax.

How does the fund pursue its investment objectives?
The fund managers buy intermediate-term, quality debt securities with interest payments exempt from
federal income tax and the Florida intangible personal property tax. Cities, counties and other
municipalities in Florida usually issue these securities for public projects, such as schools and
roads.
The fund managers also may buy intermediate-term, quality debt securities with interest payments
exempt from federal income tax and the Florida intangible personal property tax, but are not
necessarily exempt from the federal alternative minimum tax. Cities, counties and other
municipalities in Florida usually issue these securities (called private activity bonds) to fund
for-profit private projects, such as hospitals and athletic stadiums.
The fund managers also may use futures contracts and options to pursue the fund's investment
objectives.
In the event of exceptional market or economic conditions, the fund may, as a temporary defensive
measure, invest all or a substantial portion of its assets in cash or cash-equivalent securities. If
a fund assumes a defensive position, it will not be pursuing its investment objectives and may
generate taxable income.
The fund managers attempt to keep the weighted average maturity of the fund between five and 10
years.
Additional information about the fund's investments is available in its annual and semiannual

What are the principal risks of investing in the fund?
When interest rates change, the fund's share value will be affected. When interest rates rise, the
fund's share value will usually decline. The opposite is usually true when interest rates decline.
The interest rate risk is higher for Florida Intermediate-Term Municipal than for funds that have
shorter weighted average maturities, such as money market and short-term bond funds.
The fund may invest part of its assets in securities rated in the lowest investment-grade category
(for example, Baa or BBB). The issuers of these securities are more likely to pose a credit risk,
that is, to have problems making interest and principal payments.
Because the fund invests primarily in Florida municipal securities, it will be sensitive to events
that affect Florida's economy. Florida Intermediate-Term Municipal may have a higher level of risk
than funds that invest in a larger universe of securities.
As with all funds, at any given time the value of your shares of Florida Intermediate-Term Municipal
may be worth more or less than the price you paid. As a result, it is possible to lose money by
investing in the fund.

A quality debt security is one that has been determined to be in the top four credit quality
categories. This can be established in a number of ways. For example, independent rating agencies
may rate the security in their higher rating categories. The fund's advisor also can analyze an
unrated security to determine if its credit quality is high enough for investment. The details of
the fund's credit quality standards are described in the Statement of Additional Information.

Arizona Intermediate-Term Municipal Fund

What are the fund's investment objectives?
Arizona Intermediate-Term Municipal seeks safety of principal and high current income that is exempt
from federal and Arizona income taxes.

How does the fund pursue its investment objectives?
The fund managers buy intermediate-term, quality debt securities with interest payments exempt from
federal and Arizona income taxes. Cities, counties and other municipalities in Arizona usually issue
these securities for public projects, such as schools and roads.
The fund managers also may buy intermediate-term, quality debt securities with interest payments
exempt from federal and Arizona income taxes, but not exempt from the federal alternative minimum
tax. Cities, counties and other municipalities in Arizona usually issue these securities (called
private activity bonds) to fund for-profit private projects, such as hospitals and athletic stadiums.
The fund managers also may use futures contracts and options to pursue the fund's investment
objectives.
In the event of exceptional market or economic conditions, the fund may, as a temporary defensive
measure, invest all or a substantial portion of its assets in cash or cash-equivalent securities. If
a fund assumes a defensive position, it will not be pursuing its investment objectives and may
generate taxable income.
The fund managers attempt to keep weighted average maturity of the fund between five and 10 years.
Additional information about the fund's investments is available in its annual and semiannual
reports. In these reports you will find a discussion of the market conditions and investment
strategies that significantly affected the fund's performance during the most recent fiscal period.

Basics of Fixed-Income Investing


Debt Securities
When a fund buys a debt security, which is also called a fixed-income security, it is essentially
lending money to the issuer of the security. Notes, bonds, commercial paper and debentures are
examples of debt securities. After the debt security is first sold by the issuer, it may be bought
and sold by other investors. The price of the security may rise or fall based on many factors,
including changes in interest rates, liquidity and credit quality.

The fund managers decide which debt securities to buy and sell by
o  determining which securities help a fund meet its maturity requirements
o  identifying securities that satisfy a fund's credit quality standards
o  evaluating the current economic conditions and assessing the risk of inflation
o  evaluating special features of the securities that may make them more or less attractive

Weighted Average Maturity
Like most loans, debt securities eventually must be repaid (or refinanced) at some date. This date
is called the maturity date. The number of days left to a debt security's maturity date is called
the remaining maturity. The longer a debt security's remaining maturity, generally the more
sensitive its price is to changes in interest rates.
Because a bond fund will own many debt securities, the fund managers calculate the average of the
remaining maturities of all the debt securities the fund owns to evaluate the interest rate
sensitivity of the entire portfolio. This average is weighted according to the size of the fund's
individual holdings and is called weighted average maturity. The following chart shows how fund
managers would calculate the weighted average maturity for a fund that owned only two debt
securities.

                              Amount of        Percent of    Remaining       Weighted
                              Security Owned   Portfolio     Maturity        Maturity
Debt Security A               $100,000         25%           2.74 years      .69 years
Debt Security B               $300,000         75%           27.40 years     20.55 years
Weighted Average Maturity                                                    21.23 years

Types of Risk
The basic types of risk that the funds face are described below.

Interest Rate Risk
Generally, interest rates and the prices of debt securities move in opposite directions. When
interest rates fall, the prices of most debt securities rise; when interest rates rise, prices fall.
Because the funds invest primarily in debt securities, changes in interest rates will affect the
funds' performance. This sensitivity to interest rate changes is called interest rate risk.
The degree to which interest rate changes affect the funds' performance varies and is related to the
weighted average maturity of a particular fund. For example, when interest rates rise, you can
expect the share value of a long-term bond fund to fall more than that of a short-term bond fund.
When rates fall, the opposite is true.

Callout
The longer a fund's weighted average maturity, the more sensitive it is to changes in interest rates.


Weighted average maturity is a tool that the fund managers use to approximate the remaining maturity
of a fund's investment portfolio.







When interest rates change, longer maturity bonds generally experience a greater change in price.
The following table shows the likely effect of a 1% increase in interest rates on the price of 7%
coupon bonds of differing maturities:

Remaining Maturity      Current Price       Price after 1% Increase     Change in Price
1 year                  $100.00             $99.06                       -0.94%
3 years                 $100.00             $97.38                       -2.62%
10 years                $100.00             $93.20                       -6.80%
30 years                $100.00             $88.69                      -11.31%

Credit Risk
Credit risk is the risk that an obligation won't be paid and a loss will result. A high credit
rating indicates a high degree of confidence by the rating organization that the issuer will be able
to withstand adverse business, financial or economic conditions and be able to make interest and
principal payments on time. Generally, a lower credit rating indicates a greater risk of
non-payment. A lower rating also may indicate that the issuer has a more senior series of debt
securities, which means that if the issuer has difficulties making its payments, the more senior
series of debt is first in line for payment.
The fund managers do not invest solely on the basis of a security's credit rating; they also
consider other factors, including potential returns. Higher credit ratings usually mean lower
interest rate payments, so the managers often purchase securities that aren't the highest rated to
increase return. If a fund purchases lower-rated securities, it has assumed additional credit risk.
The following chart shows the authorized credit quality ranges for the funds offered by this
Prospectus.

Insert Credit Quality chart

Securities rated in one of the highest four categories by a nationally recognized securities rating
organization (e.g., Moody's or Standard & Poor's) are considered investment grade. Although they are
considered investment grade, an investment in these securities still involves some credit risk
because a AAA rating is not a guarantee of payment. For a complete description of the ratings
system, see Explanation of Fixed-Income Securities Ratings in the Statement of Additional
Information. The funds' credit quality restrictions apply at the time of purchase; the funds will
not necessarily sell securities if they are downgraded by a rating agency.

Liquidity Risk
Debt securities can become difficult to sell, or less liquid, for a variety of reasons, such as lack
of an active trading market. The chance that a fund will have liquidity issues is called liquidity
risk.

Callout
Credit quality may be lower when the issuer has

o a high debt level

o a short operating history

o a senior level of debt

o a difficult, competitive environment

o a less stable cash flow



The Statement of Additional Information provides a detailed description of these securities ratings.

The funds engage in a variety of investment techniques as they pursue their investment objectives.
Each technique has its own characteristics, and may pose some level of risk to the funds. If you
would like to learn more about these techniques, you should review the Statement of Additional
Information before making an investment.







Management


Who manages the funds?
The Board of Trustees, investment advisor and fund management team play key roles in the management
of the funds.

The Board of Trustees
The Board of Trustees oversees the management of the funds and meets at least quarterly to review
reports about fund operations. Although the Board of Trustees does not manage the funds, it has
hired an investment advisor to do so. More than two-thirds of the trustees are independent of the
funds' advisor; that is, they are not employed by and have no financial interest in the advisor.

The Investment Advisor
The funds' investment advisor is American Century Investment Management, Inc. The advisor has been
managing mutual funds since 1958 and is headquartered at 4500 Main Street, Kansas City, Missouri
64111.
The advisor is responsible for managing the investment portfolios of the funds and
directing the purchase and sale of their investment securities. The advisor also arranges for
transfer agency, custody and all other services necessary for the funds to operate.
For the services it provided to the funds during their most recent fiscal year, the advisor received
a unified management fee based on a percentage of the average net assets of the Investor Class
shares of the funds. The rate of the management fee for each fund is determined monthly on a
class-by-class basis using a two-step formula that takes into account the fund's strategy (money
market, bond or equity) and the total amount of mutual fund assets the advisor manages.
New York Municipal Money Market will pay the advisor an investment category fee rate of 0.2700% of
the first $1 billion of average net assets, 0.2270% of the next $1 billion, 0.1860% of the next $3
billion, 0.1690% of the next $5 billion, 0.1580% of the next $15 billion, 0.1575% of the next $25
billion, and 0.1570% thereafter. In addition to the investment category fee, New York Municipal
Money Market will pay the advisor a complex fee based on the total assets the advisor manages at a
rate of 0.3100% of the first $2.5 billion of average net assets, 0.3000% of the next $7.5 billion,
0.2985% of the next $15 billion, 0.2970% of the next $25 billion, 0.2960% of the next $50 billion,
0.2950% of the next $100 billion, 0.2940% of the next $100 billion, 0.2930% of the next $200
billion, 0.2920% of the next $250 billion, 0.2910% of the next $500 billion, and 0.2900% thereafter.
The Statement of Additional Information contains detailed information about the calculation of the
management fee. Out of that fee, the advisor paid all expenses of managing and operating the funds
except brokerage expenses, taxes, interest, fees and expenses of the independent trustees (including
legal counsel fees), and extraordinary expenses. A portion of the management fee may be paid by the
funds' advisor to unaffiliated third parties who provide recordkeeping and administrative services
that would otherwise be performed by an affiliate of the advisor.

Management Fees Paid by the Funds to the Advisor as a Percentage of Average Net Assets
for the Fiscal Year Ended May 31, 2000
Florida Municipal Money Market                                                  0.49%
Florida Intermediate-Term Municipal                                             0.50%
Arizona Intermediate-Term Municipal                                             0.50%






The Fund Management Team
The advisor uses teams of portfolio managers, assistant portfolio managers and analysts to manage
the funds. Teams meet regularly to review portfolio holdings and to discuss purchase and sale
activity. Team members buy and sell securities for a fund as they see fit, guided by the fund's
investment objective and strategy.
The portfolio managers who lead the investment teams are identified below.

Bryan E. Karcher
Mr. Karcher, Vice President and Portfolio Manager, has been a member of the team that manages
Florida Municipal Money Market since June 1995 and the New York Municipal Money Market team since
its inception. He joined American Century in July 1989 and has been a Portfolio Manager since June
1995. He holds a bachelor's degree in economics from the University of California - Los Angeles. He
is a Chartered Financial Analyst.

Kenneth M. Salinger
Mr. Salinger, Portfolio Manager, has been a member of the team that manages Arizona
Intermediate-Term Municipal since June 1998 and the team that manages Florida Intermediate-Term
Municipal since October 1996. He joined American Century in April 1992. He has a bachelor's degree
in quantitative economics from the University of California - San Diego. He is a Chartered Financial
Analyst.

Callout

Code of Ethics
American Century has a Code of Ethics designed to ensure that the interests of fund shareholders
come before the interests of the people who manage the funds. Among other provisions, the Code of
Ethics prohibits portfolio managers and other investment personnel from buying securities in an
initial public offering or from profiting from the purchase and sale of the same security within 60
calendar days. In addition, the Code of Ethics requires portfolio managers and other employees with
access to information about the purchase or sale of securities by the funds to obtain approval
before executing permitted personal trades.

1 The funds in this Prospectus are not available for retirement accounts.

Redemption of Shares in Low-Balance Accounts
If your redemption activity causes your account balance to fall below the minimum initial investment
amount, we will notify you and give you 90 days to meet the minimum. If you do not meet the
deadline, American Century will redeem the shares in the account and send the proceeds to your
address of record.

Abusive Trading Practices
We do not permit market timing or other abusive trading practices in our funds.
Excessive, short-term (market timing) or other abusive trading practices may disrupt portfolio
management strategies and harm fund performance. To minimize harm to the funds and their
shareholders, we reserve the right to reject any purchase order (including exchanges) from any
investor we believe has a history of abusive trading or whose trading, in our judgment, has been or
may be disruptive to a fund. In making this judgment, we may consider trading done in multiple
accounts under common ownership or control. We also reserve the right to delay delivery of your
redemption proceeds--up to seven days--or to honor certain redemptions with securities, rather than
cash, as described in the next section.

Special Requirements for Large Redemptions
If, during any 90-day period, you redeem fund shares worth more than $250,000 (or 1% of the assets
of the fund if that percentage is less than $250,000), we reserve the right to pay part or all of
the redemption proceeds in excess of this amount in readily marketable securities instead of in
cash. These securities would be selected from the fund's portfolio by the fund managers. A payment
in securities can help the fund's remaining shareholders avoid tax liabilities that they might
otherwise have incurred had the fund sold securities prematurely to pay the entire redemption amount
in cash.
We will value these securities in the same manner as we do in computing the fund's net asset value.
We may provide these securities in lieu of cash without prior notice. Also, if payment is made in
securities, a shareholder may have to pay brokerage or other transaction costs to convert the
securities to cash.
IF YOUR REDEMPTION WOULD EXCEED THIS LIMIT AND YOU WOULD LIKE TO AVOID BEING PAID IN SECURITIES,
PLEASE PROVIDE US WITH AN UNCONDITIONAL INSTRUCTION TO REDEEM AT LEAST 15 DAYS PRIOR TO THE DATE ON
WHICH THE REDEMPTION TRANSACTION IS TO OCCUR. THE INSTRUCTION MUST SPECIFY THE DOLLAR AMOUNT OR
NUMBER OF SHARES TO BE REDEEMED AND THE DATE OF THE TRANSACTION. THIS MINIMIZES THE EFFECT OF THE
REDEMPTION ON THE FUND AND ITS REMAINING SHAREHOLDERS.





Investing through Financial Intermediaries
If you do business with us through a financial intermediary, your ability to purchase, exchange and
redeem shares will depend on the policies of that entity. Some policy differences may include
o  minimum investment requirements
o  exchange policies
o  fund choices
o  cutoff time for investments
Please contact your financial intermediary for a complete description of its policies. Copies of the
funds' annual reports, semiannual reports and Statements of Additional Information are available
from your intermediary.
Certain financial intermediaries perform recordkeeping and administrative services for their clients
that would otherwise be performed by American Century's transfer agent. In some circumstances,
American Century will pay the service provider a fee for performing those services.
Although transactions in fund shares may be made directly with American Century at no charge, you
also may purchase, redeem and exchange fund shares through financial intermediaries that charge a
transaction-based or other fee for their services. Those charges are retained by the intermediary
and are not shared with American Century or the funds.
American Century has contracts with certain financial intermediaries requiring them to track the
time investment orders are received and to comply with procedures relating to the transmission of
orders. The funds have authorized those intermediaries to accept orders on each fund's behalf up to
the time at which the net asset value is determined. If those orders are transmitted to American
Century and paid for in accordance with the contract, they will be priced at the net asset value
next determined after your request is received in the form required by the intermediary on a fund's
behalf.

Callout
Financial intermediaries include banks, broker-dealers, insurance companies and investment advisors.







Share Price and Distributions


Share Price
American Century determines the net asset value (NAV) of each fund as of the close of regular
trading on the New York Stock Exchange (usually 4 p.m. Eastern time) on each day the Exchange is
open. On days when the Exchange is closed (including certain U.S. holidays), we do not calculate the
NAV. The NAV of a fund share is the current value of the fund's assets, minus any liabilities,
divided by the number of fund shares outstanding.
If current market prices of securities owned by a fund (except New York Municipal Money Market and
Florida Municipal Money Market) are not readily available, the advisor may determine their fair
value in accordance with procedures adopted by the fund's Board of Trustees. The portfolio
securities of the money market funds are valued at amortized cost. This means that the securities
are initially valued at their cost when purchased. After the initial purchase, the difference
between the purchase price and the known value at maturity will be reduced at a constant rate until
maturity. This valuation will be used regardless of the impact of interest rates on the market value
of the security. The board has adopted procedures to ensure that this type of pricing is fair to the
funds' shareholders.
We will price your purchase, exchange or redemption at the net asset value next determined after we
receive your transaction request in good order.

Distributions
Federal tax laws require each fund to make distributions to its shareholders in order to qualify as
a "regulated investment company." Qualification as a regulated investment company means that the
funds will not be subject to state or federal income tax on amounts distributed. The distributions
generally consist of dividends and interest received, as well as capital gains realized on the sale
of investment securities.
Each money market fund declares and pays distributions from net income daily. Each of the other
funds declares distributions from net income daily and pays these distributions monthly. Each fund
(except New York Municipal Money Market and Florida Municipal Money Market) generally pays
distributions of capital gains, if any, once a year usually in December. A fund may make more
frequent distributions, if necessary, to comply with Internal Revenue Code provisions.
You will participate in fund distributions, when they are declared, starting on the day after your
purchase is effective. For example, if you purchase shares on a day that a distribution is declared,
you will not receive that distribution. If you redeem shares, you will receive any distribution
declared on the day you redeem. If you redeem all shares, we will include any distribution received
with your redemption proceeds.
Participants in employer-sponsored retirement or savings plans must reinvest all distributions. For
shareholders investing through taxable accounts, we will reinvest distributions in additional shares
unless you elect to receive them in cash. Please consult our services guide for further information
regarding distributions and your distribution options.

Callout
The net asset value of a fund is the price of the fund's shares.

Capital gains are increases in the values of capital assets, such as stock, from the time the assets
are purchased. Tax becomes due on capital gains once an asset is sold.






Taxes


Tax-Exempt Income
Most of the income that the funds receive from municipal securities is exempt from
regular federal income taxes. Distributions from New York Municipal Money Market and Arizona
Intermediate-Term Municipal also will be exempt from New York and Arizona income taxes,
respectively. However, corporate shareholders should be aware that distributions may be subject to
state corporate franchise tax. Additionally, fund shares of Florida Municipal Money Market and
Florida Intermediate-Term Municipal also will generally be exempt from the Florida intangible
personal property tax.
The funds also may purchase private activity bonds. The income from these securities is subject to
the federal alternative minimum tax. If you are subject to the alternative minimum tax, then
distributions from the funds that represent income derived from private activity bonds are taxable
to you. Consult your tax advisor to determine whether you are subject to the alternative minimum tax.

Taxable Income
The funds' investment performance also is based on sources other than income from municipal
securities. These investment performance sources, while not the primary source of fund
distributions, will generate taxable income to you. Some of these investment performance sources are
o  Market Discount Purchases. The funds may buy a tax-exempt security for a price less than the
   principal amount of the bond. If the price of the bond increases over time, a portion of the gain
   may be treated as ordinary income and taxable as ordinary income if it is distributed to
   shareholders.
o  Capital Gains. When a fund sells a security, even a tax-exempt municipal security, it can
   generate a capital gain or loss, which you must report on your tax return.
o  Temporary Investments. Some temporary investments, such as securities loans and repurchase
   agreements, can generate taxable income.

Type of Distribution              Tax Rate for 15% Bracket  Tax Rate for 28% Bracket or Above
Short-term capital gains          Ordinary income rate      Ordinary income rate
Long-term capital gains           10%                       20%

The tax status of any distribution of capital gains is determined by how long a fund held the
underlying security that was sold, not by how long you have been invested in the fund or whether you
reinvest your distribution in additional shares or take them in cash. For taxable accounts, American
Century will inform you of the tax status of fund distributions for each calendar year in an annual
tax mailing (Form 1099-DIV).
Distributions also may be subject to state and local taxes. Because everyone's tax situation is
unique, always consult your tax professional about federal, state and local tax consequences.

Callout
Buying a Dividend
Purchasing fund shares in a taxable account shortly before a distribution is sometimes known as
buying a dividend. In taxable accounts, you must pay income taxes on the distribution whether you
reinvest the distribution or take it in cash. In addition, you will have to pay taxes on the
distribution whether the value of your investment decreased, increased or remained the same after
you bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable gains throughout the
period covered by a distribution, as securities are sold at a profit. We distribute those gains to
you, after subtracting any losses, even if you did not own the shares when the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution period, but you may not
enjoy the full benefit of the gains realized in the fund's portfolio.








Taxes on Transactions
Your redemptions--including exchanges to other American Century funds--are subject to capital gains
tax. The table above can provide a general guide for your potential tax liability when selling or
exchanging fund shares. Short-term capital gains are gains on fund shares you held for 12 months or
less. Long-term capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or short-term capital
loss. However, you should note that loss realized upon the sale or exchange of shares held for six
months or less will be treated as a long-term capital loss to the extent of any distribution of
long-term capital gain to you with respect to those shares. Also, any loss realized upon the sale or
exchange of shares held for six months or less will be disallowed to the extent of any distribution
of tax-exempt income to you with respect to those shares. If a loss is realized on the redemption of
fund shares, the reinvestment in additional fund shares within 30 days before or after the
redemption may be subject to the wash sale rules of the Internal Revenue Code. This may result in a
postponement of the recognition of such loss for federal income tax purposes.
If you have not certified to us that your Social Security number or tax identification number is
correct and that you are not subject to 31% withholding, we are required to withhold and pay 31% of
dividends, distributions, capital gains distributions and redemptions to the IRS.





Financial Highlights


Understanding the Financial Highlights
The tables on the next few pages itemize what contributed to the changes in share price during the
period. They also show the changes in share price for this period in comparison to changes over the
last five fiscal years.
On a per-share basis, each table includes as appropriate
o  share price at the beginning of the period
o  investment income and capital gains or losses
o  distributions of income and capital gains paid to shareholders
o  share price at the end of the period
Each table also includes some key statistics for the period as appropriate
o  Total Return - the overall percentage of return of the fund, assuming the reinvestment of all
   distributions
o  Expense Ratio - operating expenses as a percentage of average net assets
o  Net Income Ratio - net investment income as a percentage of average net assets
o  Portfolio Turnover - the percentage of the fund's buying and selling activity
The Financial Highlights for the fiscal years ended May 31, 2000, 1999 and 1998, have been audited
by PricewaterhouseCoopers LLP, independent accountants. Their report is included in the funds'
annual reports, which are incorporated by reference into the Statement of Additional Information,
and are available upon request. Prior years' information was audited by other independent auditors,
whose report also is incorporated by reference into the Statement of Additional Information.

THE FUNDS' HISTORY
American Century Municipal Trust is a registered open-end management investment company that was organized as a Massachusetts
business trust on May 1, 1984. From then until January 1997, it was known as Benham Municipal Income Trust. Throughout this
Statement of Additional Information we refer to American Century Municipal Trust as the Trust.
Each fund described in this Statement of Additional Information is a separate series of the Trust and operates for many
purposes as if it were an independent company. Each fund has its own investment objective, strategy, management team, assets,
tax identification and stock registration number.

FUND INVESTMENT GUIDELINES
This section explains the extent to which the funds' advisor, American Century Investment Management, Inc., can use various
investment vehicles and strategies in managing a fund's assets. Descriptions of the investment techniques and risks associated
with each appear in the section, Investment Strategies and Risks, which begins on page 6. In the case of the funds' principal
investment strategies, these descriptions elaborate upon discussions contained in the Prospectuses.
Each fund (except High-Yield Municipal, New York Municipal Money Market, Florida Municipal Money Market, Florida
Intermediate-Term Municipal and Arizona Intermediate-Term Municipal) is a diversified open-end investment company as defined
in the Investment Company Act of 1940 (the Investment Company Act). Diversified means that, with respect to 75% of its total
assets, each fund will not invest more than 5% of its total assets in the securities of a single issuer or own more than 10%
of the outstanding voting securities of a single issuer.
Tax-Free Money Market and Florida Municipal Money Market each operate pursuant to Rule 2a-7 under the Investment Company Act.
That rule permits the valuation of portfolio securities on the basis of amortized cost. To rely on the rule, each of these
funds must be diversified with regard to 100% of its assets other than U.S. government securities. This operating policy is
more restrictive than the Investment Company Act, which requires a diversified investment company to be diversified with
regard to only 75% of its assets.
To meet federal tax requirements for qualification as a regulated investment company, each fund must limit its investments so
that at the close of each quarter of its taxable year (1) no more than 25% of its total assets are invested in the securities
of a single issuer (other than the U.S government or a regulated investment company), and (2) with respect to at least 50% of
its total assets, no more than 5% of its total assets are invested in the securities of a single issuer (other than the U.S
government or a regulated investment company) or it does not own more than 10% of the outstanding voting securities of a
single issuer.
In general, within the restrictions outlined here and in the funds' Prospectuses, the fund managers have broad powers to
decide how to invest fund assets, including the power to hold them uninvested.
So long as a sufficient number of acceptable securities are available, the fund managers intend to keep the funds fully
invested. However, under exceptional conditions, the funds may assume a defensive position, temporarily investing all or a
substantial portion of their assets in cash or short-term securities.
For an explanation of the securities ratings referred to in the Prospectus and this Statement of Additional Information, see
Explanation of Fixed-Income Securities Ratings, beginning on page x.

Florida Municipal Money Market Fund
Florida Intermediate-Term Municipal Fund

The Florida Municipal Money Market Fund and Florida Intermediate-Term Municipal Fund seek to obtain as high a level of current
income exempt from regular federal income tax as is consistent with prudent investment management and conservation of
shareholders' capital. In addition, fund shares are intended to be exempt from the Florida Intangibles Tax.
The funds are designed for individuals in upper tax brackets seeking income free from regular federal income tax, although the
funds may generate some taxable income. The funds also provide an investment that is intended to be exempt from the Florida
Intangibles Tax. Because of this emphasis on tax-exempt income, the funds by themselves do not constitute a balanced
investment plan.
Each fund intends to remain fully invested in municipal obligations (obligations issued by or on behalf of a state, its
political subdivisions, agencies, and instrumentalities). As a fundamental policy, each fund will invest at least 80% of its
net assets in obligations with interest exempt from the regular federal income tax. The funds are not limited, however, in
their investments in securities that are subject to the Federal Alternative Minimum Tax (AMT).
In addition, each fund will invest at least 65% of its net assets in Florida municipal obligations (obligations issued by or
on behalf of Florida, its political subdivisions, agencies and instrumentalities, or U.S. possessions or territories such as
Puerto Rico). The funds sometimes invest in obligations of the Commonwealth of Puerto Rico and its public corporations (as
well as the U.S. territories of Guam and the Virgin Islands) that are exempt from federal and Florida state income taxes. The
remaining 35% of each fund's net assets may be invested in (1) obligations issued by other states and their political
subdivisions and (2) U.S. government securities.
Each fund is authorized under normal conditions to invest as much as 100% of its net assets in municipal obligations for which
the interest is a tax preference item for purposes of the AMT. If you are or become subject to the AMT, a portion of your
income distributions that are exempt from the regular federal income tax may not be exempt from the AMT. Interest from AMT
bonds is considered to be exempt from federal income tax purposes of the 80% policy noted above.
A fund may need to sell certain investments near the end of each calendar year so that on January 1 of each year, its
portfolio consists only of investments that are exempt from the Florida Intangibles Tax. As a result, a fund could incur
additional costs or taxable income or gains.

New York Municipal Money Market Fund

New York Municipal Money Market is designed for individuals in upper tax brackets seeking income free from New York state and
regular federal income taxes, although New York Municipal Money Market may generate some taxable income. Because of this
emphasis on tax-exempt income, New York Municipal Money Market does not constitute a balanced investment.
New York Municipal Money Market intends to remain fully invested in municipal obligations (obligations issued by or on behalf
of a state, its political subdivisions, agencies and instrumentalities). As a fundamental policy, New York Municipal Money
Market will invest at least 80% of its net assets in obligations with interest exempt from the regular federal income tax. New
York Municipal Money Market is not limited, however, in its investments in securities that are subject to the federal AMT.
In addition, New York Municipal Money Market will invest at least 65% of its net assets in New York municipal obligations
(obligations issued by or on behalf of the state of New York, its political subdivisions, agencies and instrumentalities) The
fund sometimes invests in obligations of the Commonwealth of Puerto Rico and its public corporations (as well as the U.S.
territories of Guam and the Virgin Islands) that are exempt from federal and Arizona state income taxes. The remaining 35% of
its net assets may be invested in (1) obligations issued by other states and their political subdivisions and (2) U.S.
government securities.
New York Municipal Money Market is authorized under normal conditions to invest as much as 100% of its net assets in municipal
obligations for which the interest is a tax preference item for purposes of the AMT. If you are or become subject to the AMT,
a portion of your income distributions that are exempt from the regular federal income tax may not be exempt from the AMT.
Interest from AMT bonds is considered to be exempt from federal income tax for purposes of the 80% policy noted above.

Arizona Intermediate-Term Municipal Fund

Arizona Intermediate-Term Municipal seeks to obtain as high a level of current income exempt from Arizona and regular federal
income tax as is consistent with prudent investment management and conservation of shareholders' capital.
Arizona Intermediate-Term Municipal is designed for individuals in upper tax brackets seeking income free from Arizona state
and regular federal income taxes, although the fund may generate some taxable income. Because of this emphasis on tax-exempt
income, the fund does not constitute a balanced investment.
The fund intends to remain fully invested in municipal obligations (obligations issued by or on behalf of a state, its
political subdivisions, agencies, and instrumentalities). As a fundamental policy, the fund will invest at least 80% of its
net assets in obligations with interest exempt from the regular federal income tax. The fund is not limited, however, in its
investments in securities that are subject to the AMT.
In addition, Arizona Intermediate-Term Municipal will invest at least 65% of its net assets in Arizona municipal obligations
(obligations issued by or on behalf of Arizona; its political subdivisions, agencies and instrumentalities). The fund
sometimes invests in obligations of the Commonwealth of Puerto Rico and its public corporations (as well as the U.S.
territories of Guam and the Virgin Islands) that are exempt from federal and Arizona state icome taxes. The remaining 35% of
its net assets may be invested in (1) obligations issued by other states and their political subdivisions and (2) U.S.
government securities.
The fund is authorized under normal conditions to invest as much as 100% of its net assets in municipal obligations for which
the interest is a tax preference item for purposes of the AMT. If you are or become subject to the AMT, a portion of your
income distributions that are exempt from the regular federal income tax may not be exempt from the AMT. Interest from AMT
bonds is considered to be exempt from federal income tax for purposes of the 80% policy noted above.

Tax-Free Money Market Fund
Limited-Term Tax-Free Fund
Intermediate-Term Tax-Free Fund
Long-Term Tax-Free Fund

Tax-Free Money Market Fund, Limited-Term Tax-Free Fund, Intermediate-Term Tax-Free Fund and Long-Term Tax-Free Fund seek as
high a level of current income exempt from regular federal income tax as is consistent with prudent investment management and
conservation of shareholders' capital.
Each fund intends to remain fully invested in municipal obligations, although for temporary defensive purposes, each may
invest a portion of its assets in U.S. government securities, the interest income on which is subject to federal income tax.
The municipal obligations in which the funds may invest include securities issued by U.S. territories or possessions, such as
Puerto Rico, provided that the interest on these securities is exempt from regular federal income tax.
The funds may invest up to 20% of their total assets in municipal obligations for which the interest is a tax preference item
for purposes of the AMT.

High-Yield Municipal Fund

High-Yield Municipal Fund seeks to provide high current income exempt from federal income tax as is consistent with its
investment policies, which permit investment in lower-rated and unrated securities. As a secondary objective, the fund seeks
capital appreciation.
The fund intends to remain fully invested in municipal obligations (obligations issued by or on behalf of a state or its
political subdivisions, agencies and instrumentalities). The fund also may invest in securities issued by U.S. territories or
possessions, such as Puerto Rico, provided that the interest on these securities is exempt from regular federal income tax. As
a fundamental policy, the fund will invest at least 80% of its net assets in obligations with interest exempt from regular
federal income tax. The fund is not limited, however, in its investments in securities that are subject to the AMT.
The fund is authorized, under normal conditions, to invest as much as 100% of its net assets in municipal obligations for
which the interest is a tax preference item for purposes of the AMT. If you are or become subject to the AMT, a portion of
your income distributions that are exempt from regular federal income tax may not be exempt from the AMT.
The fund intends to remain fully invested in municipal obligations, although for temporary defensive purposes, it may invest a
portion of its assets in U.S. government securities, the interest income on which is subject to federal income tax.

Credit Quality and Maturity Guidelines


The Money Market Funds
Tax-Free Money Market Fund and Florida Municipal Money Market Fund seek to maintain a $1.00 share price, although there is no
guarantee they will be able to do so. Shares of the funds are neither insured nor guaranteed by the U.S. government.
The money market funds may be appropriate for investors seeking share price stability who can accept the lower yields that
short-term obligations typically provide.
In selecting investments for the money market funds, the advisor adheres to regulatory guidelines concerning the quality and
maturity of money market fund investments as well as to internal guidelines designed to minimize credit risk. In particular,
each fund:
o    buys only U.S. dollar-denominated obligations with remaining maturities of 13 months or less (and variable- and
     floating-rate obligations with demand features that effectively shorten their maturities to 13 months or less)
o    maintains a dollar-weighted average portfolio maturity of 90 days or less
o    restricts its investments to high-quality obligations determined by the advisor pursuant to guidelines established by
     the Board of Trustees to present minimal credit risks.
To be considered high-quality, an obligation must be:
o    a U.S. government obligation; or
o    rated (or of an issuer rated with respect to a class of short-term obligations), within the two highest rating
     categories for short-term debt obligations by at least two nationally recognized statistical rating (or one if only one
     has rated the obligation); or
o    an unrated obligation judged by the advisor, pursuant to guidelines established by the Board of Trustees, to be of
     quality comparable to the securities listed above.
The fund managers intend to buy only obligations that are designated as first-tier securities as defined by the SEC; that is,
securities rated, when acquired, within the highest category designated by a rating agency.
The acquisition of securities that are unrated or rated by only one rating agency must be approved or ratified by the Board of
Trustees.

Non-Money Market Funds (except High-Yield Municipal)
Limited-Term Tax-Free, Intermediate-Term Tax-Free, Long-Term Tax-Free, Arizona Intermediate-Term Municipal and Florida
Intermediate-Term Municipal have identical policies governing the quality of securities in which they may invest. The funds
differ in their maturity criteria as stated in the Prospectus.
In terms of credit quality, each of these funds restricts its investments to
o    municipal bonds rated, when acquired, within the four highest categories designated by a rating agency
o    municipal notes (including variable-rate demand obligations) and tax-exempt commercial paper rated, when acquired,
     within the two highest categories designated by a rating agency
o    unrated obligations judged by the advisor, under the direction of the Board of Trustees, to be of quality comparable
     to the securities listed above.


High-Yield Municipal
Like the other non-money market funds, High-Yield Municipal invests primarily in long- and intermediate-term municipal
obligations. Although High-Yield Municipal typically invests a significant portion of its assets in investment-grade bonds,
the advisor does not adhere to specific rating criteria in selecting investments for this fund. The fund invests in securities
rated or judged by the advisor to be below investment-grade quality (e.g., bonds rated BB/Ba or lower, which are sometimes
referred to as junk bonds) or unrated bonds.
Many issuers of medium- and lower-quality bonds choose not to have their obligations rated and a large portion of High-Yield's
portfolio may consist of obligations that, when acquired, were not rated. There is no limit to the percentage of assets that
the fund may invest in unrated securities.  The fund also may invest in securities that are in technical or monetary default.
High-Yield Municipal may invest in investment-grade municipal obligations if the advisor considers it appropriate to do so.
Investments of this nature may be made due to market considerations (e.g., a limited supply of medium- and lower-grade
municipal obligations) or to increase liquidity of the fund. Investing in high-grade obligations may lower the fund's return.
High-Yield Municipal may purchase private activity municipal securities. The interest from these securities is treated as a
tax-preference item in calculating federal AMT liability. Under normal circumstances, it is possible that a substantial
PORTION of the fund's total assets will be invested in private activity securities. Therefore, the fund is better suited for
investors who do not expect alternative minimum tax liability. See Taxes, page 31.


FUND INVESTMENTS AND RISKS

INVESTMENT STRATEGIES AND RISKS

This section describes investment vehicles and strategies that the fund managers can use in managing a fund's assets. It also
details the risks associated with each, because each technique contributes to a fund's overall risk profile.

Concentration in Types of Municipal Activities
From time to time, a significant portion of a fund's assets may be invested in municipal obligations that are related to the
extent that economic, business or political developments affecting one of these obligations could affect the other obligations
in a similar manner. For example, if a fund invested a significant portion of its assets in utility bonds and a state or
federal government agency or legislative body promulgated or enacted new environmental protection requirements for utility
providers, projects financed by utility bonds could suffer as a group. Additional financing might be required to comply with
the new environmental requirements, and outstanding debt might be downgraded in the interim. Among other factors that could
negatively affect bonds issued to finance similar types of projects are state and federal legislation regarding financing for
municipal projects, pending court decisions relating to the validity or means of financing municipal projects, material or
manpower shortages and declining demand for projects or facilities financed by the municipal bonds.

About the Risks Affecting Arizona Municipal Securities
As noted in the Prospectus, the Arizona Intermediate-Term Municipal Fund is susceptible to events that affect issuers of
Arizona municipal obligations. These include possible adverse affects of Arizona constitutional amendments, legislative
measures, voter initiatives and other matters described below.
The following information about risk factors is provided in view of the fund's policy of concentrating its assets in Arizona
municipal securities. This information is based on certain official statements of the state of Arizona published in connection
with the issuance of specific Arizona municipal securities as well as from other publicly available sources. It does not
constitute a complete description of the risks associated with investing in securities of these issuers. While the advisor has
not independently verified the information contained in the official statements, it has no reason to believe the information
is inaccurate.
Located in the country's sunbelt, Arizona's population has been, and is projected to continue to be, one of the fastest
growing in the United States. Over the last several decades, the state has outpaced most other regions of the country in
population and personal income growth, gross state product and job creation.
Geographically, Arizona is the nation's sixth largest state in terms of area. It is divided into three distinct topographic
regions: the northern third, which is high plateau country traversed by deep canyons, such as Grand Canyon National Park;
central Arizona, which is rugged, mountainous and heavily forested; and the southern third, which encompasses desert areas and
flat, fertile agricultural lands in valleys between mountains rich in mineral deposits. These topographic areas all have
different climates, which have distinctively influenced development in each region.
The Phoenix metropolitan area is the state's primary economic center as it represents approximately two-thirds of the state's
population. The Tucson area while of secondary importance also is a major economic area in the state.
The Arizona economy continues to diversify away from its historical reliance on the mining and agricultural employment
sectors. Significant job growth has occurred in the areas of aerospace and high technology, construction, finance, insurance
and real estate. Arizona's economy has continued to grow in recent years, as it is among the fastest growing economies in the
nation.
Under its constitution, the state of Arizona is not permitted to issue general obligation bonds secured by the full faith and
credit of the state. However, certain agencies and instrumentalities of the state are authorized to issue bonds secured by
revenues from specific projects and activities, and the state and local governmental units may enter into lease transactions.
The particular source of payments and security for an Arizona municipal obligation is detailed in the instruments themselves
and in related offering materials.
The state and local governmental units are subject to limitations imposed by Arizona law with respect to ad valorem taxation,
bonded indebtedness, the amount of annual increases in taxes, and other matters. These limitations may affect the ability of
the issuers to generate revenues to satisfy their debt obligations. There are periodic attempts in the form of voter
initiatives and legislative proposals to further limit the amount of annual increases in taxes that may be levied without
voter approval. If such a proposal were enacted, there might be an adverse impact on state or local government financing.
Arizona is required by law to maintain a balanced budget. In the past, the state has used a combination of spending reductions
and tax increases to avoid potential budgetary shortfalls and may be required to do so again in the future.
On July 8, 1998, the Arizona state legislature passed and the governor signed, legislation that shifts the funding of public
education from local governments to the state. This was done in response to a state supreme court decision requiring the state
to deliver and implement a more equitable funding of public education. The impact of this on the state's finances in the long
term is uncertain.
A potential long-term credit concern for all states is the impact of eCommerce on tax collections. The use of the internet to
make retail purchases (eCommerce spending) is projected to increase rapidly over the next few years.  According to Forrester
Research, eCommerce spending amounted to approximately $7.8 billion in 1998 and is projected to reach $184 billion in 2004.
The proliferation of eCommerce spending could potentially impact municipal credit quality because eCommerce spending is exempt
from sales taxes.  The most vulnerable bonds would be credits secured solely by sales tax revenues.


About the Risks Affecting Florida Municipal Securities
As noted in the Prospectus, the Florida Municipal Money Market and Florida Intermediate-Term Municipal funds are susceptible
to events that affect issuers of Florida municipal obligations. These include possible adverse affects of Florida
constitutional amendments, legislative measures, voter initiatives and other matters described below.
The following information about risk factors is provided in view of the funds' policies of concentrating their assets in
Florida municipal securities. This information is based on independent municipal credit reports relating to securities
offerings of Florida issuers and other publicly available sources. It does not constitute a complete description of the risks
associated with investing in securities of these issuers. While the advisor has not independently verified this information,
it has no reason to believe the information is inaccurate.
Because the funds invest primarily in Florida municipal securities, they will be affected by political and economic conditions
and developments within the state of Florida. In general, the credit quality and credit risk of any issuer's debt depend on
the state and local economy, the health of the issuer's finances, the amount of the issuer's debt, the quality of management
and the strength of legal provisions in debt documents that protect debt holders. Credit risk is usually lower whenever the
economy is strong, growing and diversified, financial operations are sound, and the debt burden is reasonable.
The state of Florida's economy is characterized by a large service sector, a dependence on the tourism and construction
industries and a large retirement population. The management of rapid growth has been the major challenge facing state and
local governments. Florida's population has grown rapidly and is now the fourth largest state; this growth is expected to
continue, but at reduced rates. The retiree component is expected to continue to be a major factor. As this growth continues,
the demand for both public and private services will increase, which may strain the service sector's capacity and impede the
state's budget balancing efforts. For example, school districts have experienced difficulty in funding school construction as
the districts have been unable to obtain voter approval to issue debt to finance the necessary school construction.
One of the fastest growing states, Florida's economy has centered on the growing trade and services industry, further
influenced by tourism and agriculture. The state is outperforming the nation in employment and income growth. Florida ranks
twentieth among all states in personal per capita income, with a 1998 per capita income that is about 98% of the U.S figure.
Florida continues to experience steady job growth. Non-farm payroll employment growth of about 4% for 1997 through 1999
exceeds national rates for those years, and approximates the record growth rates of earlier periods in 1993 and 1994.
Preliminary employment figures for 2000 indicate continued growth at higher than national rates. Tourism, one of the main
drivers of the state's economy, will continue to grow in fiscal 2000. The state projects total tourist arrivals for 2000 at
about 51 million, a 5% increase over 1999.
Debt levels in the state of Florida are moderate to high, reflecting the tremendous capital demands associated with rapid
population growth. Florida is unusual among states in that all general obligation full faith and credit debt issues of
municipalities must be approved by public referendum and are, therefore, relatively rare. Most debt instruments issued by
local municipalities and authorities have a narrower pledge of security, such as a sales tax stream, special assessment
revenue, user fees, utility taxes or fuel taxes. Credit quality of such debt instruments tends to be somewhat lower than that
of general obligation debt. The state of Florida issues general obligation debt for a variety of purposes; however, the state
constitution requires a specific revenue stream to be pledged to state general obligation bonds as well.
The state of Florida is heavily dependent upon sales tax, which makes the state's general fund vulnerable to recession. This
dependence upon sales tax, combined with economic recession, has resulted in budgetary shortfalls in the past. Florida has
reacted to preserve an adequate financial position primarily through expenditure reductions. State officials, however, still
face tremendous capital and operating pressures due to the growth that will continue to strain the state's narrow revenue
base. As a counterbalance to the dependence on the historically volatile sales tax, the state enacted a constitutional
amendment establishing a Budget Stabilization Fund and has made yearly deposits to the Fund. At the end of fiscal 1999, the
Fund reached $787 million, meeting the required minimum fund level of 5% of General Fund revenues by 1999. The state plans on
an additional deposit of $60 million, bringing the fiscal 2000 balance to $847 million.
The state also has established a constitutional state revenue limitation to restrain the growth of spending. To date, this cap
has not yet posed a constraint. The cap, which became effective in fiscal 1996, limits the amount of taxes and other revenues
that could be raised by the state in any fiscal year. It allows annual revenue to grow by the average annual growth in
personal income over the previous five years. Exempted from the cap are revenues that are directly pledged to bonds, including
any new debt issuances. The cap does not appear to have become a major impediment to the state raising sufficient annual
revenue to fund state expenditure growth. The legislature may increase the revenue cap by a two-thirds vote of each house.
A potential long-term credit concern for all states is the impact of eCommerce on tax collections. The use of internet to make
retail purchases (eCommerce spending) is projected to increase rapidly over the next few years.  According to Forrester
Research, eCommerce spending amounted to approximately $7.8 billion in 1998 and is projected to reach $184 billion in 2004.
The proliferation of eCommerce spending could potentially impact municipal credit quality since eCommerce spending is exempt
from sales taxes.  The most vulnerable bonds would be credits secured solely by sales tax revenues.

About the Risks Affecting New York Municipal Securities
As noted in the Prospectus, New York Municipal Money Market is susceptible to events that affect issuers of New York municipal
obligations. The following information about risk factors is provided in view of the fund's policies of concentrating its
investments in New York municipal securities. This information is based on independent municipal credit reports relating to
securities offerings of New York issuers and other publicly available sources. It does not constitute a complete description
of the risks associated with investing in securities of these issuers. While the manager has not independently verified this
information, it has no reason to believe the information is inaccurate.
The fund's concentration in the debt obligations of one state carries a higher risk than a portfolio that is geographically
diversified. In addition to state general obligation bonds and notes and the debt of various state agencies, the fund will
invest in local bond issues, lease obligations and revenue bonds, the credit quality and risk of which will vary according to
each security's own structure and underlying economics.
The fund's ability to maintain a high level of "triple-tax-free" income is primarily dependent upon the ability of New York
issuers to continue to meet debt service obligations in a timely fashion. In 1975 the State, New York City and other related
issuers experienced serious financial difficulties that ultimately resulted in much lower credit ratings and loss of access to
the public debt markets. A series of fiscal reforms and an improved economic climate allowed these entities to return to
financial stability by the early 1980s. Credit ratings were reinstated or raised and access to the public credit markets was
restored. During the early 1990s, the State and City confronted renewed fiscal pressure, as the region suffered moderate
economic decline. Conditions began to improve in 1993, though below-average economic performance and tight budgetary
conditions persist. Both entities experienced financial relief in fiscal 1997 because of the strong national economy, a robust
financial services sector and vigilant spending control. The State and City continue to face challenging budgets while they
attempt to adjust spending levels and priorities.

About the Risks Affecting Puerto Rico Municipal Securities
From time to time, the funds invest in obligations of the Commonwealth of Puerto Rico and its public corporations, which are
exempt from federal, state and city or local income taxes. The majority of the Commonwealth's debt is issued by the major
public agencies that are responsible for many of the island's public functions, such as water, wastewater, highways,
telecommunications, education and public construction. As of December 31, 1999, public sector debt issued by the Commonwealth
and its public corporations totaled $22.8 billion.
Since the 1980s, Puerto Rico's economy and financial operations have paralleled the economic cycles of the United States. The
island's economy, particularly the manufacturing sector, has experienced substantial gains in employment. Much of these
economic gains have been attributable in part to favorable treatment under Section 936 of the federal Internal Revenue Code
for U.S. corporations doing business in Puerto Rico (see discussion below). The number of persons employed in Puerto Rico
during fiscal 1999 averaged more than 1.1 million. Unemployment, however, still remains high at 11.9% as of January 2000.
Debt ratios for the Commonwealth are high as it assumes much of the responsibility for local infrastructure. Sizable
infrastructure programs are ongoing to upgrade the island's water, sewer and road systems. The Commonwealth's general
obligation debt is secured by a first lien on all available revenues. The Commonwealth seeks to correlate the growth in public
sector debt to the growth of the economic base available to service that debt. However, due to the financing of certain key
infrastructure projects, between fiscal years 1996 and 1999, debt increased 28.7% while gross product rose 25.9%.
The maximum annual debt service requirement on Commonwealth general obligation debt totaled 9.5% of governmental revenues for
fiscal 1999. This is well below the 15% limit imposed by the Constitution of Puerto Rico.
The current ratio of tax-supported debt to aggregate personal income is almost 48%, about twenty times the average level of
the fifty states, and more than four times as high as the most heavily indebted of the states. The ratio is affected by the
low levels of income in Puerto Rico (per capita income is about one-third the U.S. average) and by the large absolute amount
of debt.
Puerto Rico's financial position has been adequate. Strong tax growth was offset by spending increases for health, public
education and debt service. After drawing down cash for several years, fiscal year 1998 ended with a sizable surplus resulting
in an increase in cash from 2.4% of revenues in fiscal year 1997 to 5.6% of revenues in fiscal 1998. This was primarily
attributable to several non-recurring revenue items.  Preliminary fiscal year 1999 results indicate that cash will be drawn
down to 3.5% of GF revenues with an additional drawdown expected in fiscal year 2000.
As a result of 1995 federal legislation, tax credits provided by Section 936 of the Internal Revenue Code are being phased out
over a ten-year period ending in tax year 2005. Section 936 has offered an important economic development incentive for Puerto
Rico, providing a particular impetus for the manufacturing sector. For U.S. corporations doing business in Puerto Rico,
Section 936 generally eliminated the U.S. tax on income related to their island operations. It granted these corporations tax
credits to offset federal tax liability on earnings from Puerto Rico operations (active income) and permitted them to invest
such earnings in qualified investments in Puerto Rico (passive income) with interest earned free from U.S. tax. As a result of
the 1996 legislation, the active income credit has been reduced and is no longer available to new or expanded operations in
Puerto Rico. It will also be phased out entirely after tax year 2005. The passive income credit has already been eliminated
entirely.
To offset the loss of the 936 tax credit, in 1998, the Commonwealth passed the Tax Incentives Law that provided for various
tax reduction/incentives. While this law may promote development, it must be balanced by the costs of the development in terms
of lost tax dollars. The danger Puerto Rico faces is being too generous with tax incentives, whereby, government revenues are
negatively impacted by development incentives.
Another long-term issue, with broad implications for the Commonwealth is the question of political status - specifically, the
potential for a transition to statehood, as contemplated by proposed federal legislation in 1999 and the subject of a
non-binding plebiscite in Puerto Rico in December 1998. The statehood option in the 1998 plebiscite received the support of
45.6% of the voters, about the same percentage of support in the previous plebiscite in 1993.
A final risk factor with the Commonwealth is the large amount of unfunded pension liabilities. The two main public pension
systems are largely underfunded. The combined funded ratio of the two plans is 35% with a total unfunded liability of $7
billion. A measure enacted by the legislature in 1990 is designed to address the solvency of the plans over a 50-year period.
A potential long-term credit concern for all states is the impact of eCommerce on tax collections. The use of internet to make
retail purchases (eCommerce spending) is projected to increase rapidly over the next few years. According to Forrester
Research, eCommerce spending amounted to approximately $7.8 billion in 1998 and is projected to reach $184 billion in 2004.
The proliferation of eCommerce spending could potentially impact municipal credit quality since eCommerce spending is exempt
from sales taxes.  The most vulnerable bonds would be credits secured solely by sales tax revenues.

Municipal Notes
Municipal notes are issued by state and local governments or government entities to provide short-term capital or to meet cash
flow needs.
Tax anticipation notes (TANs) are issued in anticipation of seasonal tax revenues, such as ad valorem property, income, sales,
use and business taxes, and are payable from these future taxes. Tax anticipation notes usually are general obligations of the
issuer. General obligations are secured by the issuer's pledge of its full faith and credit (i.e., taxing power) for the
payment of principal and interest.
Revenue anticipation notes (RANs) are issued with the expectation that receipt of future revenues, such as federal revenue
sharing or state aid payments, will be used to repay the notes. Typically, these notes also constitute general obligations of
the issuer.
Bond anticipation notes (BANs) are issued to provide interim financing until long-term financing can be arranged. In most
cases, the long-term bonds provide the money for repayment of the notes.
Tax-exempt commercial paper is an obligation with a stated maturity of 365 days or less issued to finance seasonal cash flow
needs or to provide short-term financing in anticipation of longer-term financing.
Revenue anticipation warrants, or reimbursement warrants, are issued to meet the cash flow needs of state governments at the
end of a fiscal year and in the early weeks of the following fiscal year. These warrants are payable from unapplied money in
the state's General Fund, including the proceeds of revenue anticipation notes issued following enactment of a state budget or
the proceeds of refunding warrants issued by the state.

Municipal Bonds
Municipal bonds, which generally have maturities of more than one year when issued, are designed to meet longer-term capital
needs. These securities have two principal classifications: general obligation bonds and revenue bonds.
General obligation (GO) bonds are issued by states, counties, cities, towns and regional districts to fund a variety of public
projects, including construction of and improvements to schools, highways, and water and sewer systems. GO bonds are backed by
the issuer's full faith and credit based on its ability to levy taxes for the timely payment of interest and repayment of
principal, although such levies may be constitutionally or statutorily limited as to rate or amount.
Revenue bonds are not backed by an issuer's taxing authority; rather, interest and principal are secured by the net revenues
from a project or facility. Revenue bonds are issued to finance a variety of capital projects, including construction or
refurbishment of utility and waste disposal systems, highways, bridges, tunnels, air and sea port facilities, schools and
hospitals. Many revenue bond issuers provide additional security in the form of a debt-service reserve fund that may be used
to make payments of interest and repayments of principal on the issuer's obligations. Some revenue bond financings are further
protected by a state's assurance (without obligation) that it will make up deficiencies in the debt-service reserve fund.
Industrial development bonds (IDBs), a type of revenue bond, are issued by or on behalf of public authorities to finance
privately operated facilities. These bonds are used to finance business, manufacturing, housing, athletic and pollution
control projects, as well as public facilities such as mass transit systems, air and sea port facilities and parking garages.
Payment of interest and repayment of principal on an IDB depend solely on the ability of the facility's user to meet financial
obligations, and on the pledge, if any, of the real or personal property financed. The interest earned on IDBs may be subject
to the federal alternative minimum tax.

Variable- and Floating-Rate Obligations
Variable- and floating-rate demand obligations (VRDOs and FRDOs) carry rights that permit holders to demand payment of the
unpaid principal plus accrued interest, from the issuers or from financial intermediaries. Floating-rate securities, or
floaters, have interest rates that change whenever there is a change in a designated base rate. Variable-rate instruments
provide for a specified, periodic adjustment in the interest rate, which typically is based on an index. These rate formulas
are designed to result in a market value for the VRDO or FRDO that approximates par value.

Obligations with Term Puts Attached
Fixed-rate bonds subject to third-party puts and participation interests in such bonds held by a bank in trust or otherwise
have tender options or demand features that permit the funds to tender (or put) their bonds to an institution at periodic
intervals and to receive the principal amount thereof.
The advisor expects that the funds will pay more for securities with puts attached than for securities without these liquidity
features. The advisor may buy securities with puts attached to keep a fund fully invested in municipal securities while
maintaining sufficient portfolio liquidity to meet redemption requests or to facilitate management of the fund's investments.
To ensure that the interest on municipal securities subject to puts is tax-exempt to the funds, the advisor limits the funds'
use of puts in accordance with applicable interpretations and rulings of the Internal Revenue Service (IRS).
Because it is difficult to evaluate the likelihood of exercise or the potential benefit of a put, puts normally will be
determined to have a value of zero, regardless of whether any direct or indirect consideration is paid. Accordingly, puts as
separate securities are not expected to affect the funds' weighted average maturities. When a fund has paid for a put, the
cost will be reflected as unrealized depreciation on the underlying security for the period the put is held. Any gain on the
sale of the underlying security will be reduced by the cost of the put.
There is a risk that the seller of a put will not be able to repurchase the underlying obligation when (or if) a fund attempts
to exercise the put. To minimize such risks, the funds will purchase obligations with puts attached only from sellers deemed
creditworthy by the advisor under the direction of the Board of Trustees.

Tender Option Bonds
Tender option bonds (TOBs) were created to increase the supply of high-quality, short-term tax-exempt obligations, and thus
they are of particular interest to the money market funds. However, any of the funds may purchase these instruments.
TOBs are created by municipal bond dealers who purchase long-term, tax-exempt bonds in the secondary market, place the
certificates in trusts, and sell interests in the trusts with puts or other liquidity guarantees attached. The credit quality
of the resulting synthetic short-term instrument is based on the guarantor's short-term rating and the underlying bond's
long-term rating.
There is some risk that the put agreement on a tender option agreement will terminate if the underlying bond is downgraded or
defaults. Because of this, the advisor monitors the credit quality of bonds underlying the funds' TOB holdings and intends to
sell or put back any TOB if the rating on its underlying bond falls below the second-highest rating category designated by a
rating agency.
The advisor also takes steps to minimize the risk that the fund may realize taxable income as a result of holding TOBs. These
steps may include consideration of (1) legal opinions relating to the tax-exempt status of the underlying municipal bonds, (2)
legal opinions relating to the tax ownership of the underlying bonds, and (3) other elements of the structure that could
result in taxable income or other adverse tax consequences. After purchase, the advisor monitors factors related to the
tax-exempt status of the fund's TOB holdings in order to minimize the risk of generating taxable income.

When-Issued and Forward Commitment Agreements
The funds may engage in municipal securities transactions on a when-issued or forward commitment basis in which the
transaction price and yield are each fixed at the time the commitment is made, but payment and delivery occur at a future date
(typically 15 to 45 days later).
When purchasing securities on a when-issued or forward commitment basis, a fund assumes the rights and risks of ownership,
including the risks of price and yield fluctuations. While the fund will make commitments to purchase or sell securities with
the intention of actually receiving or delivering them, it may sell the securities before the settlement date if doing so is
deemed advisable as a matter of investment strategy.
In purchasing securities on a when-issued or forward commitment basis, a fund will establish and maintain until the settlement
date a segregated account consisting of cash, cash equivalents or other appropriate liquid securities in an amount sufficient
to meet the purchase price. When the time comes to pay for the when-issued securities, the fund will meet its obligations with
available cash, through the sale of securities, or, although it would not normally expect to do so, by selling the when-issued
securities themselves (which may have a market value greater or less than the fund's payment obligation). Selling securities
to meet when-issued or forward commitment obligations may generate taxable capital gains or losses.
As an operating policy, no fund will commit more than 50% of its total assets to when-issued or forward commitment agreements.
If fluctuations in the value of securities held cause more than 50% of a fund's total assets to be committed under when-issued
or forward commitment agreements, the fund managers need not sell such agreements, but it will be restricted from entering
into further agreements on behalf of the fund until the percentage of assets committed to such agreements is below 50% of
total assets.

Municipal Lease Obligations
Each fund may invest in municipal lease obligations. These obligations, which may take the form of a lease, an installment
purchase, or a conditional sale contract, are issued by state and local governments and authorities to acquire land and a wide
variety of equipment and facilities. Generally, the funds will not hold such obligations directly as a lessor of the property
but will purchase a participation interest in a municipal lease obligation from a bank or other third party.
Municipal leases frequently carry risks distinct from those associated with general obligation or revenue bonds. State
constitutions and statutes set requirements that states and municipalities must meet to incur debt. These may include voter
referenda, interest rate limits or public sale requirements. Leases, installment purchases or conditional sale contracts
(which normally provide for title to the leased asset to pass to the government issuer) have evolved as a way for government
issuers to acquire property and equipment without meeting constitutional and statutory requirements for the issuance of debt.
Many leases and contracts include nonappropriation clauses, which provide that the governmental issuer has no obligation to
make future payments under the lease or contract unless money is appropriated for such purposes by the appropriate legislative
body on a yearly or other periodic basis. Municipal lease obligations also may be subject to abatement risk. For example,
construction delays or destruction of a facility as a result of an uninsurable disaster that prevents occupancy could result
in all or a portion of a lease payment not being made.

Inverse Floaters
The funds (except the money market funds) may hold inverse floaters. An inverse floater is a type of derivative that bears an
interest rate that moves inversely to market interest rates. As market interest rates rise, the interest rate on inverse
floaters goes down, and vice versa. Generally, this is accomplished by expressing the interest rate on the inverse floater as
an above-market fixed rate of interest, reduced by an amount determined by reference to a market-based or bond-specific
floating interest rate (as well as by any fees associated with administering the inverse floater program).
Inverse floaters may be issued in conjunction with an equal amount of Dutch Auction floating-rate bonds (floaters), or a
market-based index may be used to set the interest rate on these securities. A Dutch Auction is an auction system in which the
price of the security is gradually lowered until it meets a responsive bid and is sold. Floaters and inverse floaters may be
brought to market (1) by a broker-dealer who purchases fixed-rate bonds and places them in a trust or (2) by an issuer seeking
to reduce interest expenses by using a floater/inverse floater structure in lieu of fixed-rate bonds.
In the case of a broker-dealer structured offering (where underlying fixed-rate bonds have been placed in a trust),
distributions from the underlying bonds are allocated to floater and inverse floater holders in the following manner:
o  Floater holders receive interest based on rates set at a six-month interval or at a Dutch Auction, which is typically held
   every 28 to 35 days. Current and prospective floater holders bid the minimum interest rate that they are willing to accept
   on the floaters, and the interest rate is set just high enough to ensure that all of the floaters are sold.
o  Inverse floater holders receive all of the interest that remains on the underlying bonds after floater interest and auction
   fees are paid.
Procedures for determining the interest payment on floaters and inverse floaters brought to market directly by the issuer are
comparable, although the interest paid on the inverse floaters is based on a presumed coupon rate that would have been
required to bring fixed-rate bonds to market at the time the floaters and inverse floaters were issued.
Where inverse floaters are issued in conjunction with floaters, inverse floater holders may be given the right to acquire the
underlying security (or to create a fixed-rate bond) by calling an equal amount of corresponding floaters. The underlying
security may then be held or sold. However, typically, there are time constraints and other limitations associated with any
right to combine interests and claim the underlying security.
Floater holders subject to a Dutch Auction procedure generally do not have the right to "put back" their interests to the
issuer or to a third party. If a Dutch Auction fails, the floater holder may be required to hold its position until the
underlying bond matures, during which time interest on the floater is capped at a predetermined rate.
The secondary market for floaters and inverse floaters may be limited. The market value of inverse floaters tends to be
significantly more volatile than fixed-rate bonds. The interest rates on inverse floaters may be significantly reduced, even
to zero, if interest rates rise.

Lower-Quality Bonds
As indicated in the Prospectus, an investment in High-Yield Municipal carries greater risk than an investment in the other
funds because the fund may invest without limitation in lower-rated bonds and unrated bonds judged by the advisor to be of
comparable quality (collectively, lower-quality bonds).
While the market values of higher-quality bonds tend to correspond to market interest rate changes, the market values of
lower-quality bonds tend to reflect the financial condition of their issuers.
Projects financed through the issuance of lower-quality bonds are often highly leveraged. The issuer's ability to service its
debt obligations may be adversely affected by an economic downturn, a period of rising interest rates, the issuer's inability
to meet projected revenue forecasts, or a lack of needed additional financing.
Lower-quality bonds generally are unsecured and often are subordinated to other obligations of the issuer. These bonds
frequently have call or buy-back features that permit the issuer to call or repurchase the bond from the holder. Premature
disposition of a lower-quality bond due to a call or buy-back feature, deterioration of the issuer's creditworthiness, or a
default may make it difficult for the advisor to manage the flow of income to the fund, which may have negative tax
implications for shareholders.
The market for lower-quality bonds tends to be concentrated among a smaller number of dealers than the market for
higher-quality bonds. This market is dominated by dealers and institutions (including mutual funds), rather than by
individuals. To the extent that a secondary trading market for lower-quality bonds exists, it may not be as liquid as the
secondary market for higher-quality bonds. Limited liquidity in the secondary market may adversely affect market prices and
hinder the advisor's ability to dispose of particular bonds when it determines that it is in the best interest of the fund to
do so. Reduced liquidity also may hinder the advisor's ability to obtain market quotations for purposes of valuing the fund's
portfolio and determining its net asset value.
The advisor continually monitors securities to determine their relative liquidity.
A fund may incur expenses in excess of its ordinary operating expenses if it becomes necessary to seek recovery on a defaulted
bond, particularly a lower-quality bond.

Repurchase Agreements
Each fund may invest in repurchase agreements when they present an attractive short-term return on cash that is not otherwise
committed to the purchase of securities pursuant to the investment policies of that fund.
A repurchase agreement occurs when, at the time the fund purchases an interest-bearing obligation, the seller (a bank or a
broker-dealer registered under the Securities Exchange Act of 1934) agrees to purchase it on a specified date in the future at
an agreed-upon price. The repurchase price reflects an agreed-upon interest rate during the time the fund's money is invested
in the security.
Because the security purchased constitutes security for the repurchase obligation, a repurchase agreement can be considered a
loan collateralized by the security purchased. The fund's risk is the ability of the seller to pay the agreed-upon repurchase
price on the repurchase date. If the seller defaults, the fund may incur costs in disposing of the collateral, which would
reduce the amount realized thereon. If the seller seeks relief under the bankruptcy laws, the disposition of the collateral
may be delayed or limited. To the extent the value of the security decreases, the fund could experience a loss.
The funds will limit repurchase agreement transactions to securities issued by the U.S. government and its agencies and
instrumentalities, and will enter into such transactions with those banks and securities dealers who are deemed creditworthy
by the funds' advisor.
No fund will invest more than 15% of its assets in repurchase agreements maturing in more than seven days and other illiquid
securities.

Short-Term Securities
In order to meet anticipated redemptions, to hold pending the purchase of additional securities for a fund's portfolio, or, in
some cases, for temporary defensive purposes, the non-money market funds may invest a portion of their assets in money market
and other short-term securities.
Examples of those securities include:
   o  Securities issued or guaranteed by the U.S. government and its agencies and instrumentalities
   o  Commercial Paper
   o  Certificates of Deposit and Euro Dollar Certificates of Deposit
   o  Bankers' Acceptances
   o  Short-term notes, bonds, debentures or other debt instruments
   o  Repurchase agreements

    Under the Investment Company Act, a fund's investment in other investment companies (including money market funds)
currently is limited to (a) 3% of the total voting stock of any one investment company; (b) 5% of the fund's total assets with
respect to any one investment company; and (c) 10% of a fund's total assets in the aggregate. For the non-money market funds,
these investments may include investments in money market funds managed by the advisor. Any investments in money market funds
must be consistent with the investment policies and restrictions of the fund making the investment.

Futures and Options
Each non-money market fund may enter into futures contracts, options or options on futures contracts. Some futures and options
strategies, such as selling futures, buying puts and writing calls, hedge a fund's investments against price fluctuations.
Other strategies, such as buying futures, writing puts and buying calls, tend to increase market exposure. The funds do not
use futures and options transactions for speculative purposes.
Although other techniques may be used to control a fund's exposure to market fluctuations, the use of futures contracts may be
a more effective means of hedging this exposure. While a fund pays brokerage commissions in connection with opening and
closing out futures positions, these costs are lower than the transaction costs incurred in the purchase and sale of the
underlying securities.
Futures contracts provide for the sale by one party and purchase by another party of a specific security at a specified future
time and price. Futures contracts are traded on national futures exchanges. Futures exchanges and trading are regulated under
the Commodity Exchange Act by the Commodity Futures Trading Commission (CFTC), a U.S. government agency. The funds may engage
in futures and options transactions based on securities indexes such as the Bond Buyer Index of Municipal Bonds that are
consistent with the fund's investment objectives. The fund also may engage in futures and options transactions based on
specific securities such as U.S. Treasury bonds or notes.
Bond Buyer Municipal Bond Index futures contracts differ from traditional futures contracts in that when delivery takes place,
no bonds change hands. Instead, these contracts settle in cash at the spot market value of the Bond Buyer Municipal Bond Index.
Although other types of futures contracts by their terms call for actual delivery or acceptance of the underlying securities,
in most cases the contracts are closed out before the settlement date. A futures position may be closed by taking an opposite
position in an identical contract (i.e., buying a contract that has previously been sold or selling a contract that has
previously been bought).
To initiate and maintain open positions in a futures contract, a fund would be required to make a good faith margin deposit in
cash or government securities with a futures broker or custodian. A margin deposit is intended to assure completion of the
contract (delivery or acceptance of the underlying security) if it is not terminated prior to the specified delivery date.
Minimum initial margin requirements are established by the futures exchanges and may be revised. In addition, brokers may
establish margin deposit requirements that are higher than the exchange minimums.
Once a futures contract position is opened, the value of the contract is marked to market daily. If the futures contract price
changes to the extent that the margin on deposit does not satisfy margin requirements, the contract holder is required to pay
additional variation margin. Conversely, changes in the contract value may reduce the required margin, resulting in a
repayment of excess margin to the contract holder. Variation margin payments are made to or from the futures broker for as
long as the contract remains open and do not constitute margin transactions for purposes of the funds' investment restrictions.

Risks Related to Futures and Options Transactions
Futures and options prices can be volatile, and trading in these markets involves certain risks. If the advisor applies a
hedge at an inappropriate time or judges interest rate trends incorrectly, futures and options strategies may lower a fund's
return.
A fund could suffer losses if it were unable to close out its position because of an illiquid secondary market. Futures
contracts may be closed out only on an exchange that provides a secondary market for these contracts, and there is no
assurance that a liquid secondary market will exist for any particular futures contract at any particular time. Consequently,
it may not be possible to close a futures position when the advisor considers it appropriate or desirable to do so. In the
event of adverse price movements, a fund would be required to continue making daily cash payments to maintain its required
margin. If the fund had insufficient cash, it might have to sell portfolio securities to meet daily margin requirements at a
time when the advisor would not otherwise elect to do so. In addition, a fund may be required to deliver or take delivery of
instruments underlying futures contracts it holds. The advisor will seek to minimize these risks by limiting the contracts
entered into on behalf of the funds to those traded on national futures exchanges and for which there appears to be a liquid
secondary market.
A fund could suffer losses if the prices of its futures and options positions were poorly correlated with its other
investments, or if securities underlying futures contracts purchased by a fund had different maturities than those of the
portfolio securities being hedged. Such imperfect correlation may give rise to circumstances in which a fund loses money on a
futures contract at the same time that it experiences a decline in the value of its hedged portfolio securities. A fund also
could lose margin payments it has deposited with a margin broker, if, for example, the broker became bankrupt.
Most futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The
daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous
day's settlement price at the end of the trading session. Once the daily limit has been reached in a particular type of
contract, no trades may be made on that day at a price beyond the limit. However, the daily limit governs only price movement
during a particular trading day and, therefore, does not limit potential losses. In addition, the daily limit may prevent
liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting
some futures traders to substantial losses.
Options On Futures
By purchasing an option on a futures contract, a fund obtains the right, but not the obligation, to sell the futures contract
(a put option) or to buy the contract (a call option) at a fixed-strike price. A fund can terminate its position in a put
option by allowing it to expire or by exercising the option. If the option is exercised, the fund completes the sale of the
underlying security at the strike price. Purchasing an option on a futures contract does not require a fund to make margin
payments unless the option is exercised.
Although they do not currently intend to do so, the funds may write (or sell) call options that obligate it to sell (or
deliver) the option's underlying instrument upon exercise of the option. While the receipt of option premiums would mitigate
the effects of price declines, the funds would give up some ability to participate in a price increase on the underlying
security. If a fund were to engage in options transactions, it would own the futures contract at the time a call were written
and would keep the contract open until the obligation to deliver it pursuant to the call expired.
Restrictions on the Use of Futures Contracts and Options
Each non-money market fund may enter into futures contracts, options or options on futures contracts.
Under the Commodity Exchange Act, a fund may enter into futures and options transactions (a) for hedging purposes without
regard to the percentage of assets committed to initial margin and option premiums or (b) for other than hedging purposes,
provided that assets committed to initial margin and option premiums do not exceed 5% of the fund's total assets. To the
extent required by law, each fund will set aside cash and appropriate liquid assets in a segregated account to cover its
obligations related to futures contracts and options.

Restricted and Illiquid Securities
The funds may, from time to time, purchase restricted or illiquid securities, including Rule 144A securities, when they
present attractive investment opportunities that otherwise meet the funds' criteria for selection. Rule 144A securities are
securities that are privately placed with and traded among qualified institutional investors rather than the general public.
Although Rule 144A securities are considered restricted securities, they are not necessarily illiquid.
With respect to securities eligible for resale under Rule 144A, the staff of the SEC has taken the position that the liquidity
of such securities in the portfolio of a fund offering redeemable securities is a question of fact for the Board of Trustees
to determine, such determination to be based upon a consideration of the readily available trading markets and the review of
any contractual restrictions. Accordingly, the Board of Trustees is responsible for developing and establishing the guidelines
and procedures for determining the liquidity of Rule 144A securities. As allowed by Rule 144A, the Board of Trustees of the
funds has delegated the day-to-day function of determining the liquidity of Rule 144A securities to the advisor. The Board
retains the responsibility to monitor the implementation of the guidelines and procedures it has adopted.
Because the secondary market for such securities is limited to certain qualified institutional investors, the liquidity of
such securities may be limited accordingly and a fund may, from time to time, hold a Rule 144A or other security that is
illiquid. In such an event, the advisor will consider appropriate remedies to minimize the effect on such fund's liquidity.

INVESTMENT POLICIES

Unless otherwise indicated, with the exception of the percentage limitations on borrowing, the restrictions described below
apply at the time a fund enters into a transaction. Accordingly, any later increase or decrease beyond the specified
limitation resulting from a change in a fund's net assets will not be considered in determining whether it has complied with
its investment restrictions.

Fundamental Investment Policies
The funds' fundamental investment restrictions are set forth below. These investment restrictions may not be changed without
approval of a majority of the outstanding votes of shareholders of a fund, as determined in accordance with the Investment
Company Act.

Subject                 Policy
Senior Securities       A fund may not issue senior securities, except as permitted under the Investment Company Act.

Borrowing               A fund may not borrow money, except for temporary or emergency purposes (not for leveraging or
                        investment) in an amount not exceeding 331/3% of the fund's total assets.

Lending                 A fund may not lend any security or make any other loan if, as a result, more than 331/3% of the fund's
                        total assets would be lent to other parties, except (i) through the purchase of debt securities in
                        accordance with its investment objective, policies and limitations or (ii) by engaging in repurchase
                        agreements with respect to portfolio securities.

Real Estate             A fund may not purchase or sell real estate unless acquired as a result of ownership of securities or
                        other instruments. This policy shall not prevent the fund from investment in securities or other
                        instruments backed by real estate or securities of companies that deal in real estate or are engaged in
                        the real estate business.

Concentration           A fund may not concentrate its investments in securities of issuers in a particular industry (other
                        than securities issued or guaranteed by the U.S. government or any of its agencies or
                        instrumentalities).

Underwriting            A fund may not act as an underwriter of securities issued by others, except to the extent that the fund
                        may be considered an underwriter within the meaning of the Securities Act of 1933 in the disposition of
                        restricted securities.

Commodities             A fund may not purchase or sell physical commodities unless acquired as a result of ownership of
                        securities or other instruments' provided that this limitation shall not prohibit the fund from
                        purchasing or selling options and futures contracts or from investing in securities or other
                        instruments backed by physical commodities.

Control                 A fund may not invest for purposes of exercising control over management.

For purposes of the investment restrictions relating to lending and borrowing, the funds have received an exemptive order from
the SEC regarding interfund lending. Under the terms of the exemptive order, the funds may borrow money from or lend money to
other funds, advised by ACIM, that permit such transactions. All such transactions will be subject to the limits set above for
borrowing and lending. The funds will borrow money through the program only when the costs are equal to or lower than the cost
of short-term bank loans. Interfund loans and borrowings normally extend only overnight, but can have a maximum duration of
seven days. The funds will lend through the program only when the returns are higher than those available from other
short-term instruments (such as repurchase agreements). The funds may have to borrow from a bank at a higher interest rate if
an interfund loan is called or not renewed. Any delay in repayment to a lending fund could result in a lost investment
opportunity or additional borrowing costs.
For purposes of the investment restriction relating to concentration, a fund shall not purchase any securities that would
cause 25% or more of the value of the fund's total assets at the time of purchase to be invested in the securities of one or
more issuers conducting their principal business activities in the same industry, provided that (a) there is no limitation
with respect to obligations issued or guaranteed by the U.S. government, any state, territory or possession of the United
States, the District of Columbia or any of their authorities, agencies, instrumentalities or political subdivisions and
repurchase agreements secured by such instruments, (b) wholly owned finance companies will be considered to be in the
industries of their parents if their activities are primarily related to financing the activities of the parents, (c)
utilities will be divided according to their services; for example, gas, gas transmission, electric and gas, electric, and
telephone will each be considered a separate industry, and (d) personal credit and business credit businesses will be
considered separate industries.

Nonfundamental Investment Policies
In addition, the funds are subject to the following investment restrictions that are not fundamental and may be changed by the
Board of Trustees.

Subject                        Policy
Leveraging                     A fund may not purchase additional investment securities
[Tax-Free Money Market,        at any time during which outstanding borrowings exceed
Limited-Term,                  5% of the total assets of the fund.
Intermediate-Term and
Long-Term Tax-Free]
Futures and options            The money market funds may not purchase or sell
[money market funds only]      futures contracts or call options. This limitation does not
                               apply to options attached to, or acquired or traded together
                               with, their underlying securities, and does not apply to
                               securities that incorporate features similar to options
                               or futures contracts.

Liquidity                      A fund may not purchase any security or enter into a
                               repurchase agreement if, as a result, more than 15%
                               of its net assets (10% for the money market funds)
                               would be invested in illiquid securities.  Illiquid
                               securities include repurchase agreements not
                               entitling the holder to payment of principal and interest
                               within seven days, and in securities thatare illiquid by
                               virtue of legal or contractual restrictions on resale or
                               the absence of a readily available market.

Short Sales                    A fund may not sell securities short, unless it owns
                               or has the right to obtain securities equivalent in kind
                               and amount to the securities sold short, and provided
                               that transactions in futures contracts and options are
                               not deemed to constitute selling securities short.

Margin                         A fund may not purchase securities on margin, except
                               to obtain such short-term credits as are necessary for
                               the clearance of transactions, and provided that margin
                               payments in connection with futures contracts and options
                               on futures contracts shall not constitute purchasing
                               securities on margin.

TEMPORARY DEFENSIVE MEASURES
For temporary defensive purposes, a fund may invest in securities that may not fit its investment objective or its stated
market. During a temporary defensive period, a fund may direct its assets to the following investment vehicles:
(1)      interest-bearing bank accounts or Certificates of Deposit;
(2)      U.S. government securities and repurchase agreements collateralized by U.S. government securities; and
(3)      other money market funds.

PORTFOLIO TURNOVER
Under normal conditions, the funds' annual portfolio turnover rates are not expected to exceed 100%. Because a higher turnover
rate increases transaction costs and may increase taxable capital gains, the funds' managers carefully weigh the potential
benefits of short-term investing against these considerations.
The funds' portfolio turnover rates (except those of the money market funds) are listed in the Financial Highlights table in
the Prospectuses. Because of the short-term nature of the money market funds' investments, portfolio turnover rates are not
generally used to evaluate their trading activities.

MANAGEMENT
THE BOARD OF TRUSTEES
The Board of Trustees oversees the management of the funds and meets at least quarterly to review reports about fund
operations. Although the Board of Trustees does not manage the funds, it has hired the advisor to do so. Two-thirds of the
trustees are independent of the funds' advisor; that is, they are not employed by and have no financial interest in the
advisor.
The individuals listed in the table below whose names are marked by an asterisk (*) are interested persons of the funds (as
defined in the Investment Company Act) by virtue of, among other considerations, their affiliation with either the funds;
their advisor, American Century Investment Management, Inc. (ACIM); the funds' agent for transfer and administrative services,
American Century Services Corporation (ACSC); the parent corporation, American Century Companies, Inc. (ACC) or ACC's
subsidiaries (including ACIM and ACSC); the funds' distribution agent, Funds Distributor, Inc.; and the funds' other
distribution agent, American Century Investment Services, Inc. (ACIS);or other funds advised by the advisor. Each trustee
(except James E. Stowers III) listed below serves as a trustee or director of six registered investment companies in the
American Century family of funds, which are also advised by the advisor. James E. Stowers III serves as a trustee or director
of 12 other registered investment companies in the American Century family of funds.

Committees
The Board has four committees to oversee specific functions of the funds' operations. Information about these committees
appears in the table below. The trustee first named acts as chairman of the committee:

Committee       Members                Function of Committee
Audit           Kenneth E. Scott       The Audit Committee selects and oversees the
                Albert A. Eisenstat    activities of the Trust's independent auditor.
                Jeanne D. Wohlers      The committee receives reports from the
                                       advisor's Internal Audit Department, which is
                                       accountable solely to the committee.
                                       The committee also receives reporting about
                                       compliance matters affecting the Trust.
Nominating      Kenneth E. Scott       The Nominating Committee primarily considers
                Myron S. Scholes       and recommends individuals for nomination
                Albert A. Eisenstat    as trustees. The names of potential trustee
                Ronald J. Gilson       candidates are drawn from a number of sources,
                Jeanne D. Wohlers      including recommendations from members of
                                       the board, management and shareholders.
                                       This committee also reviews and makes
                                       recommendations to the board with respect to the
                                       composition of board committees and other
                                       board-related matters, including its
                                       organization, size, composition, responsibilities,
                                       functions and compensation.
Portfolio       Myron S. Scholes       The Portfolio Committee reviews quarterly the
                Ronald J. Gilson       investment activities and strategies used to
                                       manage fund assets. The committee regularly
                                       eceives reports from portfolio managers,
                                       credit analysts and other investment personnel
                                       concerning the funds' investments.
Quality of      Ronald J. Gilson       The Quality of Service Committee reviews the
Service         William Lyons          level and quality of transfer agent and
                Myron S. Scholes       administrative services provided to the funds and
                                       their shareholders. It receives and reviews
                                       reports comparing those services to fund
                                       competitors' services and seeks to improve
                                       such services where feasible and appropriate.

Compensation of Trustees
The trustees also serve as trustees for six American Century investment companies other than American Century Municipal Trust.
Each trustee who is not an interested person as defined in the Investment Company Act receives compensation for service as a
member of the board of all seven such companies based on a schedule that takes into account the number of meetings attended
and the assets of the funds for which the meetings are held. These fees and expenses are divided among the seven investment
companies based, in part, upon their relative net assets. Under the terms of the management agreement with the advisor, the
funds are responsible for paying such fees and expenses.
The following table shows the aggregate compensation paid by the Trust for the periods indicated and by the seven investment
companies served by this board to each trustee who is not an interested person as defined in the Investment Company Act.

1 Includes compensation paid to the trustees during the fiscal year ended May 31, 2000, and also includes amounts deferred at
  the election of the trustees under the Amended and Restated American Century Mutual Funds Deferred Compensation Plan for
  Non-Interested Directors. The total amount of deferred compensation included in the preceding table is as follows: Mr.
  Eisenstat, $6,489; Mr. Gilson, $6,683; Mr. Scholes, $6,404; and Mr. Scott, $3,336.
2 Includes compensation paid by the seven investment company members of the American Century family of funds served by
  this Board.
3 Mr. Stein retired from the board on September 15,2000.

The funds have adopted the Amended and Restated American Century Mutual Funds Deferred Compensation Plan for Non-Interested
Directors. Under the plan, the independent trustees may defer receipt of all or any part of the fees to be paid to them for
serving as trustees of the funds.
All deferred fees are credited to an account established in the name of the trustees. The amounts credited to the account then
increase or decrease, as the case may be, in accordance with the performance of one or more of the American Century funds that
are selected by the trustee. The account balance continues to fluctuate in accordance with the performance of the selected
fund or funds until final payment of all amounts credited to the account. Trustees are allowed to change their designation of
mutual funds from time to time.
No deferred fees are payable until such time as a trustee resigns, retires or otherwise ceases to be a member of the Board of
Trustees. Trustees may receive deferred fee account balances either in a lump-sum payment or in substantially equal
installment payments to be made over a period not to exceed 10 years. Upon the death of a trustee, all remaining deferred fee
account balances are paid to the trustee's beneficiary or, if none, to the trustee's estate.
The plan is an unfunded plan and, accordingly, the funds have no obligation to segregate assets to secure or fund the deferred
fees. To date, the funds have voluntarily funded their obligations. The rights of trustees to receive their deferred fee
account balances are the same as the rights of a general unsecured creditor of the funds. The plan may be terminated at any
time by the administrative committee of the plan. If terminated, all deferred fee account balances will be paid in a lump sum.
No deferred fees were paid to any trustee under the plan during the fiscal year ended May 31, 2000.

The funds are unaware of any other shareholders, beneficial or of record, who own more than 5% of any class of a fund's
outstanding shares. As of September 1, 2000, the officers and trustees of the funds, as a group, owned less than 1% of any
class of a fund's outstanding shares.

SERVICE PROVIDERS
The funds have no employees. To conduct the funds' day-to-day activities, the funds have hired a number of service providers.
Each service provider has a specific function to fill on behalf of the funds and is described below.
ACIM, ACSC and ACIS are both wholly owned by ACC. James E. Stowers, Jr., Chairman of ACC, controls ACC by virtue of his
ownership of a majority of its voting stock.

INVESTMENT ADVISOR

A description of the responsibilities of the advisor appears in the Prospectus under the heading Management.
For the services provided to the funds, the advisor receives a monthly fee based on a percentage of the average net assets of
a fund. The annual rate at which this fee is assessed is determined monthly in a two-step process. First, a fee rate schedule
is applied to the assets of all the funds of its investment category managed by the advisor (the Investment Category Fee). For
example, when calculating the fee for a money market fund, all the assets of the money market funds managed by the advisor are
aggregated. The three investment categories are money market funds, bond funds and equity funds. Second, a separate fee rate
schedule is applied to the assets of all the funds managed by the advisor (the Complex Fee). The Investment Category Fee and
the Complex Fee are then added to determine the unified management fee payable by a fund to the advisor.
The schedules by which the unified management fee is determined are shown below. The Investment Category Fees are determined
according to the schedule below.
Investment Category Fee Schedule for :
Tax-Free Money Market, Florida Municipal Money Market
and New York Municipal Money Market

Category Assets            Fee Rate
First $1 billion           0.2700%

On the first business day of each month, the funds pay a management fee to the advisor for the previous month at the specified
rate. The fee for the previous month is calculated by multiplying the applicable fee for the fund by the aggregate average
daily closing value of a fund's net assets during the previous month. This number is then multiplied by a fraction, the
numerator of which is the number of days in the previous month and the denominator of which is 365 (366 in leap years).
The management agreement between the Trust and the advisor shall continue in effect until the earlier of the expiration of two
years from the date of its execution or until the first meeting of shareholders following such execution and for as long
thereafter as its continuance is specifically approved at least annually, by (1) the funds' Board of Trustees, or by the vote
of a majority of outstanding votes (as defined in the Investment Company Act) and (2) by the vote of a majority of the
trustees of the funds who are not parties to the agreement or interested persons of the advisor, cast in person at a meeting
called for the purpose of voting on such approval.
The management agreement provides that it may be terminated at any time without payment of any penalty by the funds' Board of
Trustees, or by a vote of a majority of outstanding votes, on 60 days' written notice to the advisor, and that it shall be
automatically terminated if it is assigned.
The management agreement states that the advisor shall not be liable to the funds or their shareholders for anything other
than willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations and duties. The management
agreement also provides that the advisor and its officers, trustees and employees may engage in other business, devote time
and attention to any other business whether of a similar or dissimilar nature, and render services to others.
Certain investments may be appropriate for the funds and also for other clients advised by the advisor. Investment decisions
for the funds and other clients are made with a view to achieving their respective investment objectives after consideration
of such factors as their current holdings, availability of cash for investment and the size of their investment generally. A
particular security may be bought or sold for only one client or fund, or in different amounts and at different times for more
than one but less than all clients or funds. In addition, purchases or sales of the same security may be made for two or more
clients or funds on the same date. Such transactions will be allocated among clients in a manner believed by the advisor to be
equitable to each. In some cases this procedure could have an adverse effect on the price or amount of the securities
purchased or sold by a fund.
The advisor may aggregate purchase and sale orders of the funds with purchase and sale orders of its other clients when the
advisor believes that such aggregation provides the best execution for the funds. The Board of Trustees has approved the
policy of the advisor with respect to the aggregation of portfolio transactions. Where portfolio transactions have been
aggregated, the funds participate at the average share price for all transactions in that security on a given day and share
transaction costs on a pro rata basis. The advisor will not aggregate portfolio transactions of the funds unless it believes
that such aggregation is consistent with its duty to seek best execution on behalf of the funds and the terms of the
management agreement. The advisor receives no additional compensation or remuneration as a result of such aggregation.
Prior to August 1, 1997, Benham Management Corporation served as the investment advisor to the funds. Benham Management
Corporation was merged into the advisor in late 1997.

DISTRIBUTORS

The funds' shares are distributed by FDI and ACIS, both registered broker-dealers. FDI is a wholly owned indirect subsidiary
of Boston Institutional Group, Inc. FDI's principal business address is 60 State Street, Suite 1300, Boston, Massachusetts
02109. ACIS is a wholly owned subsidiary of ACC, and is located at 4500 Main Street, Kansas City, Missouri 64111.
The distributors are the principal underwriters of the funds' shares. The distributors make a continuous, best-efforts
underwriting of the funds' shares. This means the distributors have no liability for unsold shares.

OTHER SERVICE PROVIDERS

CUSTODIAN BANKS

Chase Manhattan Bank, 770 Broadway, 10th floor, New York, New York 10003-9598, and Commerce Bank, N.A., 1000 Walnut, Kansas
City, Missouri 64105, each serve as custodian of the assets of the funds. The custodians take no part in determining the
investment policies of the funds or deciding which securities are purchased or sold by the funds. The funds, however, may
invest in certain obligations of the custodians and may purchase or sell certain securities from or to the custodians.

INDEPENDENT ACCOUNTANTS

PricewaterhouseCoopers LLP are the independent accountants of the funds. The address of PricewaterhouseCoopers LLP is 1055
Broadway, 10th floor, Kansas City, Missouri 64105. As the independent accountants of the funds, PricewaterhouseCoopers
provides services including (1) audit of the annual financial statements for each fund, (2) assistance and consultation in
connection with SEC filings, and (3) review of the annual federal income tax return filed for each fund.

BROKERAGE ALLOCATION
The fund generally purchases and sells debt securities through principal transactions, meaning that the funds normally
purchase securities directly from the issuer or a primary market-maker acting as principal for the securities on a net basis.
The funds do not pay brokerage commissions on these transactions, although the purchase price for debt securities usually
includes an undisclosed compensation. Purchases from underwriters or securities typically include a commission or concession
paid by the issuer to the underwriter, and purchases from dealers serving as market-makers typically include a dealer's
mark-up (i.e., a spread between the bid and asked prices). During the fiscal years ended May 31, 1998, 1998 and 2000, the
funds did not pay any brokerage commissions.

INFORMATION ABOUT FUND SHARES
Each of the funds named on the front of this Statement of Additional Information is a series of shares issued by the Trust,
and shares of each fund have equal voting rights.
Each fund votes separately on matters affecting that fund exclusively. Voting rights are not cumulative, so that investors
holding more than 50% of the Trust's (i.e., all funds') outstanding shares may be able to elect a Board of Trustees. The Trust
undertakes dollar-based voting, meaning that the number of votes a shareholder is entitled to is based upon the dollar amount
of the shareholder's investment. The election of trustees is determined by the votes received from all Trust shareholders
without regard to whether a majority of shares of any one fund voted in favor of a particular nominee or all nominees as a
group.
Each shareholder has rights to dividends and distributions declared by the fund he or she owns and to the net assets of such
fund upon its liquidation or dissolution proportionate to his or her share ownership interest in the fund.
Shareholders of a Massachusetts business trust could, under certain circumstances, be held personally liable for its
obligations. However, the Declaration of Trust contains an express disclaimer of shareholder liability for acts or obligations
of the Trust. The Declaration of Trust also provides for indemnification and reimbursement of expenses of any shareholder held
personally liable for obligations of the Trust. The Declaration of Trust provides that the Trust will, upon request, assume
the defense of any claim made against any shareholder for any act or obligation of the Trust and satisfy any judgment thereon.
The Declaration of Trust further provides that the Trust may maintain appropriate insurance (for example, fidelity, bonding
and errors and omissions insurance) for the protection of the Trust, its shareholders, trustees, officers, employees and
agents to cover possible tort and other liabilities. Thus, the risk of a shareholder incurring financial loss as a result of
shareholder liability is limited to circumstances in which both inadequate insurance exists and the Trust is unable to meet
its obligations.

BUYING AND SELLING FUND SHARES

Information about buying, selling and exchanging fund shares is contained in the funds' prospectuses and in Your Guide to
American Century Services. The prospectuses and guide are available to investors without charge and may be obtained by calling
us.

VALUATION OF A FUND'S SECURITIES

Each fund's net asset value per share (NAV) is calculated as of the close of business of the New York Stock Exchange (the
Exchange) each day the Exchange is open for business. The Exchange usually closes at 4 p.m. Eastern time. The Exchange
typically observes the following holidays: New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. Although the funds expect the same holidays to be
observed in the future, the Exchange may modify its holiday schedule at any time.
Each fund's NAV is calculated by adding the value of all portfolio securities and other assets, deducting liabilities and
dividing the result by the number of shares outstanding. Expenses and interest earned on portfolio securities are accrued
daily.

Money Market Funds
Securities held by the money market funds are valued at amortized cost. This method involves valuing an instrument at its cost
and thereafter assuming a constant amortization to maturity of any discount or premium paid at the time of purchase. Although
this method provides certainty in valuation, it generally disregards the effect of fluctuating interest rates on an
instrument's market value. Consequently, the instrument's amortized cost value may be higher or lower than its market value,
and this discrepancy may be reflected in the funds' yields. During periods of declining interest rates, for example, the daily
yield on fund shares computed as described above may be higher than that of a fund with identical investments priced at market
value. The converse would apply in a period of rising interest rates.
The money market funds operate pursuant to Investment Company Act Rule 2a-7, which permits valuation of portfolio securities
on the basis of amortized cost. As required by the rule, the Board of Trustees has adopted procedures designed to stabilize,
to the extent reasonably possible, a money market fund's price per share as computed for the purposes of sales and redemptions
at $1.00. While the day-to-day operation of the money market funds has been delegated to the fund managers, the quality
requirements established by the procedures limit investments to certain instruments that the Board of Trustees has determined
present minimal credit risks and that have been rated in one of the two highest rating categories as determined by a rating
agency or, in the case of unrated securities, of comparable quality. The procedures require review of the money market funds'
portfolio holdings at such intervals as are reasonable in light of current market conditions to determine whether the money
market funds' net asset values calculated by using available market quotations deviate from the per-share value based on
amortized cost. The procedures also prescribe the action to be taken if such deviation should occur.
The Board of Trustees monitors the levels of illiquid securities, however if the levels are exceeded, they will take action to
rectify these levels.
Actions the Board of Trustees may consider under these circumstances include (i) selling portfolio securities prior to
maturity, (ii) withholding dividends or distributions from capital, (iii) authorizing a one-time dividend adjustment, (iv)
discounting share purchases and initiating redemptions in kind, or (v) valuing portfolio securities at market price for
purposes of calculating NAV.

Non-Money Market Funds
Securities held by the non-money market funds normally are priced by an independent pricing service, provided that such prices
are believed by the advisor to reflect the fair market value of portfolio securities.
Because there are hundreds of thousands of municipal issues outstanding, and the majority of them do not trade daily, the
prices provided by pricing services are generally determined without regard to bid or last sale prices. In valuing securities,
the pricing services generally take into account institutional trading activity, trading in similar groups of securities, and
any developments related to specific securities. The methods used by the pricing service and the valuations so established are
reviewed by the advisor under the general supervision of the Board of Trustees. There are a number of pricing services
available, and the advisor, on the basis of ongoing evaluation of these services, may use other pricing services or
discontinue the use of any pricing service in whole or in part.
Securities not priced by a pricing service are valued at the mean between the most recently quoted bid and ask prices provided
by broker-dealers. The municipal bond market is typically a "dealer market"; that is, dealers buy and sell bonds for their own
accounts rather than for customers. As a result, the spread, or difference, between bid and asked prices for certain municipal
bonds may differ substantially among dealers.
Debt securities maturing within 60 days of the valuation date may be valued at cost, plus or minus any amortized discount or
premium, unless the trustees determine that this would not result in fair valuation of a given security. Other assets and
securities for which quotations are not readily available are valued in good faith at their fair value using methods approved
by the Board of Trustees.

TAXES

Federal Income Tax

Each fund intends to qualify annually as a regulated investment company under Subchapter M of the Internal Revenue Code of
1986, as amended (the Code). By so qualifying, a fund will be exempt from federal and state income taxes to the extent that it
distributes substantially all of its net investment income and net realized capital gains (if any) to shareholders. If a fund
fails to qualify as a regulated investment company, it will be liable for taxes, significantly reducing its distributions to
shareholders and eliminating shareholders' ability to treat distributions of the funds in the manner in which they were
realized by the funds.
Certain of the bonds purchased by the funds may be treated as bonds that were originally issued at a discount. Original issue
discount represents interest for federal income tax purposes and can generally be defined as the difference between the price
at which a security was issued and its stated redemption price at maturity. Original issue discount, although no cash is
actually received by a fund until the maturity of the bond, is treated for federal income tax purposes as income earned by a
fund over the term of the bond, and therefore is subject to the distribution requirements of the Code. The annual amount of
income earned on such a bond by a fund generally is determined on the basis of a constant yield to maturity that takes into
account the semiannual compounding of accrued interest. Original issue discount on an obligation with interest exempt from
federal income tax will constitute tax-exempt interest income to the fund.
In addition, some of the bonds may be purchased by a fund at a discount that exceeds the original issue discount on such
bonds, if any. This additional discount represents market discount for federal income tax purposes. The gain realized on the
disposition of any bond having market discount generally will be treated as taxable ordinary income to the extent it does not
exceed the accrued market discount on such bond (unless a fund elects to include market discount in income in tax years to
which it is attributable). Generally, market discount accrues on a daily basis for each day the bond is held by a fund on a
straight line basis over the time remaining to the bond's maturity. In the case of any debt security having a fixed maturity
date of not more than one year from date of issue, the gain realized on disposition generally will be treated as short-term
capital gain. In general, gain realized on disposition of a security held less than one year is treated as a short-term
capital gain.
Under the Code, any distribution of a fund's net realized long-term capital gains designated by the fund as a capital gain
dividend is taxable to you as long-term capital gains, regardless of the length of time shares are held. If a capital gain
dividend is paid with respect to any shares of a fund sold at a loss after being held for six months or less, the loss will be
treated as a long-term capital loss to the extent of any distribution of long-term capital gain.

Alternative Minimum Tax
While the interest on bonds issued to finance essential state and local government operations is generally exempt from regular
federal income tax, interest on certain private activity bonds issued after August 7, 1986, while exempt from regular federal
income tax, constitutes a tax-preference item for taxpayers in determining alternative minimum tax liability under the Code
and income tax provisions of several states.
The funds may each invest in private activity bonds. The interest on private activity bonds could subject a shareholder to, or
increase liability under, the federal alternative minimum tax, depending on the shareholder's tax situation.
All distributions derived from interest exempt from regular federal income tax may subject corporate shareholders to, or
increase their liability under, the alternative minimum tax because these distributions are included in the corporation's
adjusted current earnings.
The Trust will inform fund shareholders annually of the amount of distributions derived from interest payments on private
activity bonds.

HOW FUND PERFORMANCE INFORMATION IS CALCULATED
The funds may quote performance in various ways. Historical performance information will be used in advertising and sales
literature.
For the money market funds, seven-day current yield quotations are based on the change in the value of a hypothetical
investment (excluding realized gains and losses from the sale of securities and unrealized appreciation and depreciation of
securities) over a seven-day period (base period) and stated as a percentage of the investment at the start of the base period
(base-period return). The base-period return is then annualized by multiplying by 365/7 with the resulting yield figure
carried to at least the nearest hundredth of one percent.
Calculations of seven-day effective yield begin with the same base-period return used to calculate yield, but the return is
then annualized to reflect weekly compounding according to the following formula:
                                                                               365/7
                                     Effective Yield = [(Base-Period Return + 1)    ] - 1

The 30-day SEC yield calculation for non-money market funds is as follows:

                                                  YIELD = 2 [(a - b + 1)6 - 1]
--------------------------------------------------------------------------------------------------------------------------------
                                                               cd

where a = dividends and interest earned during the period, b = expenses accrued for the period (net of reimbursements), c =
the average daily number of shares outstanding during the period that were entitled to receive dividends, and d = the maximum
offering price per share on the last day of the period.

The funds also may quote tax-equivalent yields. Tax-equivalent yields for Tax-Free Money Market, Limited-Term Tax-Free,
Intermediate-Term Tax-Free, Long-Term Tax-Free and High-Yield Municipal are calculated using the following equation:

 Fund's Tax-Free Yield    = Your Tax-Equivalent Yield
--------------------------------------------------------------------------------------------------------------------------------
100% - Federal Tax Rate

New York Municipal Money Market and Arizona Intermediate-Term Municipal's tax-equivalent yield is based on the current double
tax-exempt yield and your combined federal and state marginal tax rate. Assuming all the funds' dividends are tax-exempt in
your state (which may not always be the case) and that your state taxes are fully deductible for federal income tax purposes,
you can calculate your tax equivalent yield for the fund using the equation below.

                                                  Fund's Double Tax-Free Yield
--------------------------------------------------------------------------------------------------------------------------------
                                       (100% - Federal Tax Rate) (100% - State Tax Rate)
                                                  = Your Tax-Equivalent Yield

Florida Municipal Money Market and Florida Intermediate-Term Municipal's tax-equivalent yield is based on each fund's tax-free
yield, your federal income tax bracket, and the Florida Intangibles Tax applicable to a taxable investment. The formula is:

 Fund's Tax-Free Yield    +   Florida Intangibles Tax Rate
--------------------------------------------------------------------------------------------------------------------------------
100% - Federal Tax Rate
                                                  = Your Tax-Equivalent Yield

Total returns quoted in advertising and sales literature reflect all aspects of a fund's return, including the effect of
reinvesting dividends and capital gains distributions (if any) and any change in the fund's NAV during the period.
Average annual total returns are calculated by determining the growth or decline in value of a hypothetical historical
investment in a fund during a stated period and then calculating the annually compounded percentage rate that would have
produced the same result if the rate of growth or decline in value had been constant throughout the period. For example, a
cumulative total return of 100% over 10 years would produce an average annual return of 7.18%, which is the steady annual rate
that would equal 100% growth on a compounded basis in 10 years. While average annual total returns are a convenient means of
comparing investment alternatives, investors should realize that the funds' performance is not constant over time, but changes
from year to year, and that average annual total returns represent averaged figures as opposed to actual year-to-year
performance.
In addition to average annual total returns, each fund may quote unaveraged or cumulative total returns reflecting the simple
change in value of an investment over a stated period, including periods other than one, five and 10 years. Average annual and
cumulative total returns may be quoted as percentages or as dollar amounts and may be calculated for a single investment, a
series of investments, or a series of redemptions over any time period. Total returns may be broken down into their components
of income and capital (including capital gains and changes in share price) to illustrate the relationship of these factors and
their contributions to total return.

Explanation of Fixed-Income Securities Ratings
As described in the Prospectus, the funds may invest in fixed-income securities. Those investments, however, are subject to
certain credit quality restrictions, as noted in the Prospectus. The following is a summary of the rating categories
referenced in the prospectus disclosure.
Bond Ratings


S&P        Moody's       Description
AAA        Aaa           These are the highest ratings assigned by S&P and Moody's to a debt obligation. They indicate an
                         extremely strong capacity to pay interest and repay principal.
AA         Aa            Debt rated in this category is considered to have a very strong capacity to pay interest and repay
                         principal and differs from AAA/Aaa issues only in a small degree.
A          A             Debt rated A has a strong capacity to pay interest and repay principal, although it is somewhat more
                         susceptible to the adverse effects of changes in circumstances and economic conditions than debt in
                         higher-rated categories.
BBB        Baa           Debt rated BBB/Baa is regarded as having an adequate capacity to pay interest and repay principal.
                         Whereas it normally exhibits adequate protection parameters, adverse economic conditions or changing
                         circumstances are more likely to lead to a weakened capacity to pay interest and repay principal for
                         debt in this category than in higher-rated categories.
BB         Ba            Debt rated BB/Ba has less near-term vulnerability to default than other speculative issues. However,
                         it faces major ongoing uncertainties or exposure to adverse business, financial or economic conditions
                         that could lead to inadequate capacity to meet timely interest and principal payments. The BB/Ba
                         rating category also is used for debt subordinated to senior debt that is assigned an actual or
                         implied BBB- rating.
B          B             Debt rated B has a greater vulnerability to default but currently has the capacity to meet interest
                         payments and principal repayments. Adverse business, financial or economic conditions will likely
                         impair capacity or willingness to pay interest and repay principal. The B rating category is also used
                         for debt subordinated to senior debt that is assigned an actual or implied BB/Ba or BB-/Ba3 rating.
CCC        Caa           Debt rated CCC/Caa has a currently identifiable vulnerability to default and is dependent upon
                         favorable business, financial and economic conditions to meet timely payment of interest and repayment
                         of principal. In the event of adverse business, financial or economic conditions, it is not likely to
                         have the capacity to pay interest and repay principal. The CCC/Caa rating category is also used for
                         debt subordinated to senior debt that is assigned an actual or implied B or B-/B3 rating.
CC         Ca            The rating CC/Ca typically is applied to debt subordinated to senior debt that is assigned an actual
                         or implied CCC/Caa rating.
C          C             The rating C typically is applied to debt subordinated to senior debt, which is assigned an actual or
                         implied CCC-/Caa3 debt rating. The C rating may be used to cover a situation where a bankruptcy
                         petition has been filed, but debt service payments are continued.
CI        --             The rating CI is reserved for income bonds on which no interest is being paid.
D          D             Debt rated D is in payment default. The D rating category is used when interest payments or principal
                         payments are not made on the date due even if the applicable grace period has not expired, unless S&P
                         believes that such payments will be made during such grace period. The D rating also will be used upon
                         the filing of a bankruptcy petition if debt service payments are jeopardized.

To provide more detailed indications of credit quality, the Standard & Poor's ratings from AA to CCC may be modified by the
addition of a plus or minus sign to show relative standing within these major rating categories. Similarly, Moody's adds
numerical modifiers (1,2,3) to designate relative standing within its major bond rating categories. Fitch Investors Service,
Inc. also rates bonds and uses a ratings system that is substantially similar to that used by Standard & Poor's.
Commercial Paper Ratings


S&P        Moody's           Description
A-1        Prime-1 (P-1)     This indicates that the degree of safety regarding timely payment is strong. Standard & Poor's
                             rates those issues determined to possess extremely strong safety characteristics as A-1+.
A-2        Prime-2 (P-2)     Capacity for timely payment on commercial paper is satisfactory, but the relative degree of safety
                             is not as high as for issues designated A-1. Earnings trends and coverage ratios, while sound,
                             will be more subject to variation. Capitalization characteristics, while still appropriated, may
                             be more affected by external conditions. Ample alternate liquidity is maintained.
A-3        Prime-3 (P-3)     Satisfactory capacity for timely repayment. Issues that carry this rating are somewhat more
                             vulnerable to the adverse changes in circumstances than obligations carrying the higher
                             designations.

Note Ratings


S&P        Moody's           Description
SP-1       MIG-1; VMIG-1     Notes are of the highest quality enjoying strong protection from established cash flows of funds
                             for their servicing or from established and broad-based access to the market for refinancing, or
                             both.
SP-2       MIG-2; VMIG-2     Notes are of high quality with margins of protection ample, although not so large as in the
                             preceding group.
SP-3       MIG-3; VMIG-3     Notes are of favorable quality with all security elements accounted for, but lacking the
                             undeniable strength of the preceding grades. Market access for refinancing, in particular, is
                             likely to be less well established.
SP-4       MIG-4; VMIG-4     Notes are of adequate quality, carrying specific risk but having protection and not distinctly or
                             predominantly speculative.

AN OVERVIEW OF THE FUNDS

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?


These funds seek high current income and investment returns that are exempt from
federal income tax and taxes imposed by Florida or Arizona.


WHAT ARE THE FUNDS' PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS?


The fund managers invest most of the funds' assets in DEBT SECURITIES issued by
cities, counties and other municipalities, and U.S. territories. Each of the
funds invests in different types of these municipal debt securities and has
different risks. The following chart shows the differences among the funds'
primary investments and principal risks. It is designed to help you compare
these funds with each other; it should not be used to compare these funds with
other mutual funds. A more detailed description about the funds' investment
strategies and risks begins on page 7.

As with all funds, your shares may be worth more or less at any given time than
the price you paid. As a result, it is possible to lose money by investing in
the funds.


WHO MAY WANT TO INVEST IN THE FUNDS?

The funds may be a good investment if you are

*  a Florida or Arizona resident or taxpayer
*  seeking current tax-free income
*  comfortable with risk based on Florida's or Arizona's economy
*  comfortable with the funds' other investment risks
*  seeking diversification by investing in a fixed-income mutual fund

WHO MAY NOT WANT TO INVEST IN THE FUNDS?

The funds may not be a good investment if you are


*  investing in an IRA or other tax-advantaged retirement plan
*  investing for long-term growth
*  looking for the added security of FDIC insurance

DEBT SECURITIES include fixed-income investments such as notes, bonds,
commercial paper and debentures.

An investment in the funds is not a bank deposit, and it is not insured or
guaranteed by the Federal Deposit Insurance Corporation (FDIC) or any other
government agency. Although the Florida Money Market Fund seeks to preserve the
value of your investment at $1.00 per share, it is possible to  lose money by
investing in it.

OBJECTIVES, STRATEGIES AND RISKS

FLORIDA MUNICIPAL MONEY MARKET FUND

WHAT ARE THE FUND'S INVESTMENT OBJECTIVES?

Florida Municipal Money Market seeks safety of principal and high current income
that is exempt from federal income tax and seeks to be exempt from the Florida
intangible personal property tax.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVES?


The fund managers buy cash-equivalent, HIGH-QUALITY DEBT SECURITIES with
interest payments exempt from federal income tax and the Florida intangible
personal property tax. Cities, counties and other municipalities in Florida
usually issue these securities for public projects, such as schools and roads.

The fund managers also may buy cash-equivalent, high-quality debt securities
with interest payments exempt from federal income tax and from the Florida
intangible personal property tax, but not exempt from the federal alternative
minimum tax. Cities, counties and other municipalities in Florida usually issue
these securities (called private activity bonds) to fund for-profit private
projects, such as hospitals and athletic stadiums.

Additional information about the fund's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.


WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

Because cash-equivalent securities are among the safest securities available,
the interest they pay is among the lowest for income-paying securities.
Accordingly, the yield on this fund will likely be lower than funds that invest
in longer-term or lower-quality securities.

Because the fund invests primarily in Florida municipal securities, it will be
sensitive to events that affect Florida's economy. Florida Municipal Money
Market may have a higher level of risk than funds that invest in a larger
universe of securities.


[left margin]
[graphic of pointing finger]
Income from the fund may be subject to the alternative minimum tax. For more
information, see Taxes in this Prospectus.


A HIGH-QUALITY DEBT SECURITY is one that has been determined to be in the top
two credit quality categories. This can be established in a number of ways. For
example, independent rating agencies may rate the security in their higher
rating categories. The fund's advisor also can analyze an unrated security to
determine if its credit quality is high enough for investment. The details of
the fund's credit quality standards are described in the Statement of Additional
Information.

FLORIDA INTERMEDIATE-TERM MUNICIPAL FUND

WHAT ARE THE FUND'S INVESTMENT OBJECTIVES?

Florida Intermediate-Term Municipal seeks safety of principal and high current
income that is exempt from federal income tax and seeks to be exempt from the
Florida intangible personal property tax.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVES?


The fund managers buy intermediate-term, QUALITY DEBT SECURITIES with interest
payments exempt from federal income tax and the Florida intangible personal
property tax. Cities, counties and other municipalities in Florida usually issue
these securities for public projects, such as schools and roads.

The fund managers also may buy intermediate-term, quality debt securities with
interest payments exempt from federal income tax and which are exempt from the
Florida  intangible personal property tax, but are not necessarily exempt from
the federal  alternative minimum tax. Cities, counties and other municipalities
in Florida usually  issue these securities (called private activity bonds) to
fund for-profit private projects, such as hospitals and athletic stadiums.


The fund managers also may use futures contracts and options to pursue the
fund's investment objectives.


In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash or cash-equivalent securities. If a fund assumes a defensive position,
it will not be pursuing its investment objectives and may generate taxable
income.

The fund managers attempt to keep the WEIGHTED AVERAGE MATURITY of the fund
between five and 10 years.

Additional information about the fund's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.


WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?


When interest rates change, the fund's share value will be affected. When
interest rates rise, the fund's share value will usually decline. The opposite
is usually true when interest rates decline. The interest rate risk is higher
for Florida Intermediate-Term Municipal  than for funds that have shorter
weighted average maturities, such as money market and short-term bond funds.


The fund may invest part of its assets in securities rated in the lowest
investment-grade category (for example, Baa or BBB). The issuers of these
securities are more likely to pose a credit risk, that is, to have problems
making interest and principal payments.

Because the fund invests primarily in Florida municipal securities, it will be
sensitive to events that affect Florida's economy. Florida Intermediate-Term
Municipal may have a higher level of risk than funds that invest in a larger
universe of securities.


As with all funds, at any given time the value of your shares of Florida
Intermediate-Term Municipal may be worth more or less than the price you paid.
As a result, it is possible to lose money by investing in the fund.

BASICS OF FIXED-INCOME INVESTING

DEBT SECURITIES


When a fund buys a debt security, which is also called a fixed-income security,
it is essentially lending money to the issuer of the security. Notes, bonds,
commercial paper and debentures are examples of debt securities. After the debt
security is first sold by the issuer, it may be bought and sold by other
investors. The price of the security may rise or fall based on many factors,
including changes in interest rates, liquidity and credit quality.


The fund managers decide which debt securities to buy and sell by

*  determining which securities help a fund meet its maturity requirements


*  identifying securities that satisfy a fund's credit quality standards


*  evaluating the current economic conditions and assessing the risk of
   inflation

*  evaluating special features of the securities that may make them more or less
   attractive

WEIGHTED AVERAGE MATURITY


Like most loans, debt securities eventually must be repaid (or refinanced) at
some date. This date is called the maturity date. The number of days left to a
debt security's maturity date is called the remaining maturity. The longer a
debt security's remaining maturity, generally the more sensitive its price is to
changes in interest rates.

Because a bond fund will own many debt securities, the fund managers calculate
the average of the remaining maturities of all the debt securities the fund owns
to evaluate the interest rate sensitivity of the entire portfolio. This average
is weighted according to the size of the fund's individual holdings and is
called WEIGHTED AVERAGE MATURITY. The following chart shows how fund managers
would calculate the weighted average maturity for a fund that owned only two
debt securities.

                                Amount of         Percent of    Remaining       Weighted
                                Security Owned    Portfolio     Maturity        Maturity
--------------------------------------------------------------------------------------------
Debt Security A                 $100,000          25%            2.74 years       .69 years
--------------------------------------------------------------------------------------------
Debt Security B                 $300,000          75%           27.40 years     20.55 years
--------------------------------------------------------------------------------------------
Weighted Average Maturity                                                       21.23 years


TYPES OF RISK

The basic types of risk that the funds face are described below.

Interest Rate Risk


Generally, interest rates and the prices of debt securities move in opposite
directions. When interest rates fall, the prices of most debt securities rise;
when interest rates rise, prices fall. Because the funds invest primarily in
debt securities, changes in interest rates will affect the funds' performance.
This sensitivity to interest rate changes is called interest rate risk.

The degree to which interest rate changes affect the funds' performance varies
and is related to the weighted average maturity of a particular fund. For
example, when interest rates rise, you can expect the share value of a long-term
bond fund to fall more than that of a short-term bond fund. When rates fall, the
opposite is true.

The longer a fund's weighted average maturity, the more sensitive it is to
changes in interest rates.

WEIGHTED AVERAGE MATURITY is a  tool that the fund managers use to approximate
the remaining maturity  of a fund's investment portfolio.

When interest rates change, longer maturity bonds generally experience a greater
change in price. The following table shows the likely effect of a 1% increase in
interest rates on the price of 7% coupon bonds of differing maturities:

Remaining Maturity     Current Price     Price after 1% Increase     Change in Price

Credit Risk

Credit risk is the risk that an obligation won't be paid and a loss will result.
A high credit rating indicates a high degree of confidence by the rating
organization that the issuer will be able to withstand adverse business,
financial or economic conditions and be able to make interest and principal
payments on time. Generally, a lower credit rating indicates a greater risk of
non-payment. A lower rating also may indicate that the issuer has a more senior
series of debt securities, which means that if the issuer has difficulties
making its payments, the more senior series of debt is first in line for
payment.


The fund managers do not invest solely on the basis of a security's credit
rating; they also consider other factors, including potential returns. Higher
credit ratings usually mean lower interest rate payments, so the managers often
purchase securities that aren't the highest rated to increase return. If a fund
purchases lower-rated securities, it has assumed additional credit risk.


The following chart shows the authorized credit quality ranges for the funds
offered by this Prospectus.

---------------------------------------------------------------  --------------------------------------------


Securities rated in one of the highest four categories by a nationally
recognized securities rating organization (e.g., Moody's or Standard & Poor's)
are considered "investment grade." Although they are considered investment
grade, an investment in these securities still involves some credit risk because
a AAA rating is not a guarantee of payment. For a complete description of the
ratings system, see Explanation of Fixed-Income Securities Ratings in the
Statement of Additional Information. The funds' credit quality restrictions
apply at the time of purchase; the funds will not necessarily sell securities if
they are downgraded by a rating agency.


Liquidity Risk

Debt securities can become difficult to sell, or less liquid, for a variety of
reasons, such as lack of an active trading market. The chance that a fund will
have liquidity issues is called liquidity risk.

Credit quality may be lower when the issuer has

* a high debt level
* a short operating history
* a senior level of debt
* a difficult, competitive environment
* a less stable cash flow

securities ratings.

MANAGEMENT

WHO MANAGES THE FUNDS?

The Board of Trustees, investment advisor and fund management team play key
roles in the management of the funds.

THE BOARD OF TRUSTEES

The Board of Trustees oversees the management of the funds and meets at least
quarterly to review reports about fund operations. Although the Board of
Trustees does not manage the funds, it has hired an investment advisor to do so.
More than two-thirds of the trustees are independent of the funds' advisor; that
is, they are not employed by and have no financial interest in the advisor.

THE INVESTMENT ADVISOR

The funds' investment advisor is American Century Investment Management, Inc.
The advisor has been managing mutual funds since 1958 and is headquartered at
4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible for managing the investment portfolios of the funds
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the funds to operate.

For the services it provided to the funds during their most recent fiscal year,
the advisor received a unified management fee based on a percentage of the
average net assets of the Investor Class shares of the funds. The rate of the
management fee for each fund is determined monthly on a class-by-class basis
using a two-step formula that takes into account the fund's strategy (money
market, bond or equity) and the total amount of mutual fund assets the advisor
manages.

The Statement of Additional Information contains detailed information about the
calculation of the management fee. Out of that fee, the advisor paid all
expenses of managing and operating the funds except brokerage expenses, taxes,
interest, fees and expenses of the independent trustees (including legal counsel
fees), and extraordinary expenses. A portion of the management fee may be paid
by the funds' advisor to unaffiliated third parties who provide recordkeeping
and administrative services that would otherwise be performed by an affiliate of
the advisor.

Management Fees Paid by the Funds to the Advisor as a Percentage
of Average Net Assets for the Fiscal Year Ended May 31, 2000

www.americancentury.com                   American Century Investments     13


THE FUND MANAGEMENT TEAM

The advisor uses teams of portfolio managers, assistant portfolio managers and
analysts  to manage the funds. Teams meet regularly to review portfolio holdings
and to discuss purchase and sale activity. Team members buy and sell securities
for a fund as they see fit, guided by the fund's investment objective and
strategy.

The portfolio managers who lead the investment teams are identified below.

BRYAN E. KARCHER


Mr. Karcher, Vice President and Portfolio Manager, has been a member of the team
that manages Florida Municipal Money Market since June 1995. He joined American
Century in July 1989 and has been a Portfolio Manager since June 1995. He holds
a bachelor's degree in economics from the University of California - Los
Angeles. He is a Chartered Financial Analyst.


KENNETH M. SALINGER


Mr. Salinger, Portfolio Manager, has been a member of the team that manages
Arizona Intermediate-Term Municipal since June 1998 and the team that manages
Florida  Intermediate-Term Municipal since October 1996. He joined American
Century in April 1992. He has a bachelor's degree in quantitative economics from
the University of  California - San Diego. He is a Chartered Financial Analyst.


FUNDAMENTAL INVESTMENT POLICIES

Fundamental investment policies contained in the Statement of Additional
Information and the investment objectives of the funds may not be changed
without a shareholder vote. The Board of Trustees may change any other policies
and investment strategies.

[left margin]
[graphic of pointing finger]
Code of Ethics

American Century has a Code of Ethics designed to ensure that the interests of
fund shareholders come before the interests of the people who manage the funds.
Among other provisions, the Code of Ethics prohibits portfolio managers and
other investment personnel from buying securities in an initial public offering
or from profiting from the purchase and sale of the same security within 60
calendar days. In addition, the Code of Ethics requires portfolio managers and
other employees with access to information about the purchase or sale of
securities by the funds to obtain approval before executing permitted personal
trades.

REDEMPTION OF SHARES IN LOW-BALANCE ACCOUNTS

If your redemption activity causes your account balance to fall below the
minimum initial investment amount, we will notify you and give you 90 days to
meet the minimum. If you do not meet the deadline, American Century will redeem
the shares in the account and send the proceeds to your address of record.

ABUSIVE TRADING PRACTICES

We do not permit market timing or other abusive trading practices in our funds.

Excessive, short-term (market timing) or other abusive trading practices may
disrupt portfolio management strategies and harm fund performance. To minimize
harm to the funds and their shareholders, we reserve the right to reject any
purchase order (including exchanges) from any investor we believe has a history
of abusive trading or whose trading, in our judgment, has been or may be
disruptive to a fund. In making this judgment, we may consider trading done in
multiple accounts under common ownership or control. We also reserve the right
to delay delivery of your redemption proceeds--up to seven days--or to honor
certain redemptions with securities, rather than cash, as described in the next
section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS


If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the assets of the fund if that percentage is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. These
securities would be selected from the fund's portfolio by the fund managers. A
payment in securities can help the fund's remaining shareholders avoid tax
liabilities that they might otherwise have incurred had the fund sold securities
prematurely to pay the entire redemption amount in cash.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, a shareholder may have to
pay brokerage or other transaction costs to convert the securities to cash.


If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the transaction. This minimizes the effect of the
redemption on the fund and its remaining shareholders.

INVESTING THROUGH FINANCIAL INTERMEDIARIES


If you do business with us through a financial intermediary, your ability to
purchase, exchange and redeem shares will depend on the policies of that entity.
Some policy  differences may include


*  minimum investment requirements
*  exchange policies
*  fund choices
*  cutoff time for investments


Please contact your financial intermediary for a complete description of its
policies. Copies of the funds' annual reports, semiannual reports and Statement
of Additional Information are available from your intermediary.


Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, American Century will pay the
service provider a fee for performing those services.

Although transactions in fund shares may be made directly with American Century
at no charge, you also may purchase, redeem and exchange fund shares through
financial intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the intermediary and are not shared with
American Century or the funds.

American Century has contracts with certain financial intermediaries requiring
them to track the time investment orders are received and to comply with
procedures relating to the transmission of orders. The funds have authorized
those intermediaries to accept orders on each fund's behalf up to the time at
which the net asset value is determined. If those orders are transmitted to
American Century and paid for in accordance with the contract, they will be
priced at the net asset value next determined after your request is received in
the form required by the intermediary on a fund's behalf.

[left margin]
[graphic of pointing finger]
Financial intermediaries include banks, broker-dealers, insurance companies and
investment advisors.

SHARE PRICE AND DISTRIBUTIONS

SHARE PRICE


American Century determines the NET ASSET VALUE (NAV) of each fund as of the
close of regular trading on the New York Stock Exchange (usually 4 p.m. Eastern
time) on each  day the Exchange is open. On days when the Exchange is closed
(including certain U.S. holidays), we do not calculate the NAV. The NAV of a
fund share is the current value of the fund's assets, minus any liabilities,
divided by the number of fund shares outstanding.

If current market prices of securities owned by a fund (except Florida Municipal
Money Market) are not readily available, the advisor may determine their fair
value in accordance with procedures adopted by the fund's Board of Trustees. The
portfolio securities of Florida Municipal Money Market are valued at amortized
cost. This means that the  securities are initially valued at their cost when
purchased. After the initial purchase, the difference between the purchase price
and the known value at maturity will be reduced  at a constant rate until
maturity. This valuation will be used regardless of the impact of interest rates
on the market value of the security. The board has adopted procedures to ensure
that this type of pricing is fair to the fund's shareholders.


We will price your purchase, exchange or redemption at the net asset value next
determined after we receive your transaction request in good order.

DISTRIBUTIONS

Federal tax laws require each fund to make distributions to its shareholders in
order to qualify as a "regulated investment company." Qualification as a
regulated investment company means that the funds will not be subject to state
or federal income tax on amounts distributed. The distributions generally
consist of dividends and interest received, as well as CAPITAL GAINS realized on
the sale of investment securities.


Florida Municipal Money Market declares and pays distributions from net income
daily. Each of the other funds declares distributions from net income daily and
pays these distributions monthly. Each fund (except Florida Municipal Money
Market) generally  pays distributions of capital gains, if any, once a year
usually in December. A fund  may make more frequent distributions, if necessary,
to comply with Internal Revenue Code provisions.


You will participate in fund distributions, when they are declared, starting on
the day after your purchase is effective. For example, if you purchase shares on
a day that a  distribution is declared, you will not receive that distribution.
If you redeem shares, you will receive any distribution declared on the day you
redeem. If you redeem all shares,  we will include any distribution received
with your redemption proceeds.


Participants in employer-sponsored retirement or savings plans must reinvest all
distributions. For shareholders investing through taxable accounts, we will
reinvest distributions in additional shares unless you elect to receive them in
cash. Please consult our services guide for further information regarding
distributions and your distribution options.


[left margin]
The NET ASSET VALUE of a fund is the price of the fund's shares.

CAPITAL GAINS are increases in the values of capital assets, such as stock, from
the time the assets are purchased. Tax becomes due on capital gains once an
asset is sold.


www.americancentury.com                   American Century Investments        19


TAXES

Tax-Exempt Income


Most of the income that the funds receive from municipal securities is exempt
from regular federal income taxes. Distributions from Arizona Intermediate-Term
Municipal also will be exempt from Arizona income taxes. However, corporate
shareholders should be aware that distributions may be subject to state
corporate franchise tax. Additionally, fund shares of Florida Municipal Money
Market and Florida Intermediate-Term Municipal will generally be exempt from the
Florida intangible personal property tax.

The funds also may purchase private activity bonds. The income from these
securities is subject to the federal alternative minimum tax. If you are subject
to the alternative minimum tax, then distributions from the funds that represent
income derived from private activity bonds are taxable to you. Consult your tax
advisor to determine whether you are subject to the alternative minimum tax.


Taxable Income

The funds' investment performance also is based on sources other than income
from municipal securities. These investment performance sources, while not the
primary source of fund distributions, will generate taxable income to you. Some
of these investment performance sources are

*  Market Discount Purchases. The funds may buy a tax-exempt security for a
   price less than the principal amount of the bond. If the price of the bond
   increases over time, a portion of the gain may be treated as ordinary income
   and taxable as ordinary income if it is distributed to shareholders.

*  Capital Gains. When a fund sells a security, even a tax-exempt municipal
   security, it can generate a capital gain or loss, which you must report on
   your tax return.

*  Temporary Investments. Some temporary investments, such as securities loans
   and repurchase agreements, can generate taxable income.

Type of Distribution        Tax Rate for 15% Bracket   Tax Rate for 28% Bracket or Above
-----------------------------------------------------------------------------------------
Short-term capital gains    Ordinary income rate       Ordinary income rate
-----------------------------------------------------------------------------------------
Long-term capital gains     10%                        20%


The tax status of any distribution of capital gains is determined by how long a
fund held the underlying security that was sold, not by how long you have been
invested in the fund or whether you reinvest your distribution in additional
shares or take them in cash. For taxable accounts, American Century will inform
you of the tax status of fund distributions for each calendar year in an annual
tax mailing (Form 1099-DIV).


Distributions also may be subject to state and local taxes. Because everyone's
tax  situation is unique, always consult your tax professional about federal,
state and local  tax consequences.

[left margin]
[graphic of pointing finger]
Buying a Dividend

Purchasing fund shares in a taxable account shortly before a distribution is
sometimes known as buying a dividend. In taxable accounts, you must pay income
taxes on the distribution whether you reinvest the distribution or take it in
cash. In addition, you will have to pay taxes on the distribution whether the
value of your investment decreased, increased or remained the same after you
bought the fund shares.

The risk in buying a dividend is that a fund's portfolio may build up taxable
gains throughout the period covered  by a distribution, as securities are sold
at a profit. We distribute those gains to you, after subtracting any losses,
even  if you did not own the shares when  the gains occurred.

If you buy a dividend, you incur the full tax liability of the distribution
period, but you may not enjoy the full benefit of the gains realized in the
fund's portfolio.

Taxes on Transactions


Your redemptions--including exchanges to other American Century funds--are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. Also, any loss realized upon the sale
or exchange of shares held for six months or less will be disallowed to the
extent of any distribution  of tax-exempt income to you with respect to those
shares. If a loss is realized on the redemption of fund shares, the reinvestment
in additional fund shares within 30 days before or after the redemption may be
subject to the wash sale rules of the Internal Revenue Code. This may result in

AN OVERVIEW OF THE FUNDS

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

These funds seek high current income and investment returns that are exempt from
federal income tax.

High-Yield Municipal also seeks capital appreciation as a secondary objective.

WHAT ARE THE FUNDS' PRIMARY INVESTMENT STRATEGIES AND PRINCIPAL RISKS?


The fund managers invest most of the funds' assets in DEBT SECURITIES issued by
cities, counties and other municipalities, and U.S. territories. Each of the
funds invests in different types of these municipal debt securities and has
different risks. The following chart shows the differences among the funds'
primary investments and principal risks. It is designed to help you compare
these funds with each other; it should not be used to compare these funds with
other mutual funds. A more detailed description about the funds' investment
strategies and risks begins on page 7.

FUND                        PRIMARY INVESTMENTS                    PRINCIPAL RISKS
----------------------------------------------------------------------------------------------
Tax-Free Money Market       High-quality, very short-term          Low credit risk
                            debt securities
----------------------------------------------------------------------------------------------
Limited-Term Tax-Free       Quality debt securities that mature    Credit risk
                            in five years or less                  Low interest rate risk
----------------------------------------------------------------------------------------------
Intermediate-Term Tax-Free  Quality debt securities that mature    Credit risk
                            in five to 10 years                    Interest rate risk
----------------------------------------------------------------------------------------------
Long-Term Tax-Free          Quality debt securities that mature    Credit risk
                            in 10 years or more                    High interest rate risk
----------------------------------------------------------------------------------------------
High-Yield Municipal        Debt securities that provide           High credit risk
                            high income, including junk            High interest rate risk
                            and private activity bonds

As with all funds, your shares may be worth more or less at any given time than
the price you paid. As a result, it is possible to lose money by investing in
the funds.


WHO MAY WANT TO INVEST IN THE FUNDS?

The funds may be a good investment if you are

*  seeking current tax-free income

*  seeking diversification by investing in a fixed-income mutual fund

*  comfortable with the funds' other investment risks

WHO MAY NOT WANT TO INVEST IN THE FUNDS?

The funds may not be a good investment if you are


*  investing in an IRA or other tax-advantaged retirement plan


*  investing for long-term growth

*  looking for the added security of FDIC insurance

[left margin]

DEBT SECURITIES INCLUDE FIXED-INCOME INVESTMENTS SUCH AS NOTES, BONDS,
COMMERCIAL PAPER AND DEBENTURES.

[graphic of pointing finger]
AN INVESTMENT IN THE FUNDS IS NOT A BANK DEPOSIT, AND IT IS NOT INSURED OR
GUARANTEED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION (FDIC) OR ANY OTHER
GOVERNMENT AGENCY. ALTHOUGH THE TAX-FREE MONEY MARKET FUND SEEKS TO PRESERVE
THE VALUE OF YOUR INVESTMENT AT $1.00 PER SHARE, IT IS POSSIBLE TO LOSE MONEY
BY INVESTING IN IT.

OBJECTIVES, STRATEGIES AND RISKS

TAX-FREE MONEY MARKET FUND

WHAT ARE THE FUND'S INVESTMENT OBJECTIVES?

Tax-Free Money Market seeks safety of principal and high current income that is
exempt from federal income tax.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVES?


The fund managers buy cash-equivalent, HIGH-QUALITY DEBT SECURITIES with
interest payments exempt from federal income tax. Cities, counties and other
municipalities in the 50 states and U.S. territories usually issue these
securities for public projects, such as schools and roads.

The fund managers also may buy cash-equivalent, high-quality debt securities
with interest payments exempt from regular federal income tax, but not exempt
from the federal alternative minimum tax. Cities, counties and other
municipalities usually issue these securities (called private activity bonds) to
fund for-profit private projects, such as hospitals and athletic stadiums. No
more than 20% of the fund's total assets may be invested in these securities.


Additional information about the fund's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?


Because cash-equivalent securities are among the safest securities available,
the interest they pay is among the lowest for interest-paying securities.
Accordingly, the yield on this fund will likely be lower than funds that invest
in longer-term or lower-quality securities.


Because the fund invests primarily in municipal securities, it will be sensitive
to events that affect municipal markets. Tax-Free Money Market may have a higher
level of risk than funds that invest in a larger universe of securities.

INCOME FROM THE FUND MAY BE SUBJECT  TO THE ALTERNATIVE MINIMUM TAX. FOR  MORE
INFORMATION, SEE Taxes IN  THIS PROSPECTUS.


A HIGH-QUALITY DEBT SECURITY IS ONE THAT HAS BEEN DETERMINED TO BE IN THE TOP
TWO CREDIT QUALITY CATEGORIES. THIS CAN BE ESTABLISHED IN A NUMBER OF WAYS. FOR
EXAMPLE, INDEPENDENT RATING AGENCIES MAY RATE THE SECURITY IN THEIR HIGHER
RATING CATEGORIES. THE FUND'S ADVISOR ALSO CAN ANALYZE AN UNRATED SECURITY TO
DETERMINE IF ITS CREDIT QUALITY IS HIGH ENOUGH FOR INVESTMENT. THE DETAILS OF
THE FUND'S CREDIT QUALITY STANDARDS ARE DESCRIBED IN THE STATEMENT OF
ADDITIONAL INFORMATION.

LIMITED-TERM TAX-FREE FUND
INTERMEDIATE-TERM TAX-FREE FUND
LONG-TERM TAX-FREE FUND

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

These funds seek safety of principal and high current income that is exempt
from federal income tax.

HOW DO THE FUNDS PURSUE THEIR INVESTMENT OBJECTIVES?


The fund managers buy QUALITY DEBT SECURITIES with interest payments exempt from
federal income tax. Cities, counties and other municipalities in the 50 states
and U.S. territories usually issue these securities for public projects, such as
schools and roads.

The fund managers also may buy quality debt securities with interest payments
exempt from regular federal income tax, but not exempt from the federal
alternative minimum tax. Cities, counties and other municipalities usually issue
these securities (called private activity bonds) to fund for-profit private
projects, such as hospitals and athletic stadiums. No more than 20% of the
funds' total assets may be invested in these securities.


The funds may purchase securities in a number of different ways to seek higher
rates of return. For example, by using when-issued and forward commitment
transactions, the funds may purchase securities in advance to generate
additional income.


In the event of exceptional market or economic conditions, the funds may, as a
temporary defensive measure, invest all or a substantial portion of their assets
in cash or cash-equivalent securities. If a fund assumes a defensive position,
it will not be pursuing its investment objectives and may generate taxable
income.


Additional information about the funds' investments is available in their annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
funds' performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

WHAT IS THE DIFFERENCE BETWEEN THE FUNDS?

The funds differ in the maturity of the debt securities they purchase. This
difference is shown on the chart below.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUNDS?

The funds have different WEIGHTED AVERAGE MATURITIES. Because of this, the funds
will respond differently to changes in interest rates. Funds with longer
weighted average maturities are more sensitive to interest rate changes. When
interest rates rise, the values of the funds usually fall, but the values of
funds with longer weighted average maturities generally will fall farther.

The funds may invest part of their assets in securities rated in the lowest
investment-grade category (for example, BBB). The issuers of these securities
are more likely to pose a credit risk, that is, to have problems making interest
and principal payments than issuers of higher-rated securities.

Because these funds invest primarily in municipal securities, they will be
sensitive to events that affect municipal markets. The funds may have a higher
level of risk than funds that invest in a larger universe of securities.


As with all funds, at any given time the value of your shares may be worth more
or less than the price you paid. As a result, it is possible to lose money by
investing in the funds.


The funds' share values will fluctuate. In general, the funds that have higher
potential income have a higher potential loss.

HIGH-YIELD MUNICIPAL FUND

WHAT ARE THE FUND'S INVESTMENT OBJECTIVES?

High-Yield Municipal seeks high current income that is exempt from federal
income tax. Capital appreciation is a secondary objective.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVES?


The fund managers buy long- and intermediate-term debt securities with interest
payments exempt from federal income tax. Cities, counties and other
municipalities in the 50 states and U.S. territories usually issue these
securities for public projects, such as schools and roads.

The fund managers also may buy long- and intermediate-term debt securities with
interest payments exempt from regular federal income tax, but not exempt from
the federal alternative minimum tax. Cities, counties and other municipalities
usually issue these securities (called private activity bonds) to fund
for-profit private projects, such as hospitals and athletic stadiums.

The fund managers buy securities that are rated below investment grade,
including  so-called junk bonds. Issuers of these securities often have short
financial histories or have questionable credit or have had and may continue to
have problems making interest and principal payments.

The fund managers also may buy unrated securities if they determine such
securities meet the investment objective of the fund.

Although High-Yield Municipal invests primarily for income, it also employs
techniques designed to realize capital appreciation. For example, the fund
managers may select bonds with maturities and coupon rates that position the
fund for potential capital appreciation for a variety of reasons, including
their view on the direction of future interest-rate movements and the potential
for a credit upgrade.

In the event of exceptional market or economic conditions, the fund may, as a
temporary defensive measure, invest all or a substantial portion of its assets
in cash or cash-equivalent securities. If a fund assumes a defensive position,
it will not be pursuing its investment objectives and may generate taxable
income.

The fund managers attempt to keep the WEIGHTED AVERAGE MATURITY of the fund at
10 years or longer.


Additional information about the fund's investments is available in its annual
and semiannual reports. In these reports you will find a discussion of the
market conditions and investment strategies that significantly affected the
fund's performance during the most recent fiscal period. You may get these
reports at no cost by calling us.

WHAT ARE THE PRINCIPAL RISKS OF INVESTING IN THE FUND?

When interest rates change, the fund's share value will be affected. Generally,
when interest rates rise, the fund's share value will decline. The opposite is
true when interest rates decline. This interest rate risk is higher for
High-Yield Municipal than for funds that have shorter weighted average
maturities, such as short-term and intermediate-term funds.


The fund's investments often have high credit risk, which helps it pursue a
higher yield than more conservatively managed bond funds. Issuers of high-yield
securities are more vulnerable to real or perceived economic changes (such as an
economic downturn or a prolonged period of rising interest rates), political
changes or adverse developments specific to the issuer.  Adverse economic,
political and other developments may be more likely to cause an issuer of
low-quality bonds to default on its obligation to pay interest and principal due
under its securities.

The fund may invest part of its assets in securities rated below investment
grade or that are unrated, including bonds that are in technical or monetary
default. By definition, the issuers of many of these securities have had and may
continue to have problems making interest and principal payments.

The market for lower-quality debt securities is generally less liquid than the
market for higher-quality securities. Adverse publicity and investor
perceptions, as well as new and proposed laws, also may have a greater negative
impact on the market for lower-quality securities.


Some or all of the fund's income may be subject to the federal alternative
minimum tax.

Because the fund invests primarily in municipal securities, it will be sensitive
to events that affect municipal markets. High-Yield Municipal may have a higher
level of risk than funds that invest in a larger universe of securities.


As with all funds, at any given time the value of your shares of High-Yield
Municipal may be worth more or less than the price you paid. As a result, it is
possible to lose money by investing in the fund.

BASICS OF FIXED-INCOME INVESTING

DEBT SECURITIES


When a fund buys a debt security, which is also called a fixed-income security,
it is essentially lending money to the issuer of the security. Notes, bonds,
commercial paper and debentures are examples of debt securities. After the debt
security is first sold by the issuer, it may be bought and sold by other
investors. The price of the security may rise or fall based on many factors,
including changes in interest rates, liquidity and credit quality.


The fund managers decide which debt securities to buy and sell by

*  determining which securities help a fund meet its maturity requirements


*  identifying securities that satisfy a fund's credit quality standards


*  evaluating the current economic conditions and assessing the risk of
   inflation

*  evaluating special features of the securities that may make them more or less
   attractive

WEIGHTED AVERAGE MATURITY


Like most loans, debt securities eventually must be repaid (or refinanced) at
some date. This date is called the maturity date. The number of days left to a
debt security's maturity date is called the remaining maturity. The longer a
debt security's remaining maturity, generally the more sensitive its price is to
changes in interest rates.

Because a bond fund will own many debt securities, the fund managers calculate
the average of the remaining maturities of all the debt securities the fund owns
to evaluate the interest rate sensitivity of the entire portfolio. This average
is weighted according to the size of the fund's individual holdings and is
called weighted average maturity. The following chart shows how fund managers
would calculate the WEIGHTED AVERAGE MATURITY for a fund that owned only two
debt securities.

                       AMOUNT OF            PERCENT OF       REMAINING         WEIGHTED

Debt Security A        $100,000             25%               2.74 years         .69 years
-------------------------------------------------------------------------------------------
Debt Security B        $300,000             75%              27.40 years       20.55 years
-------------------------------------------------------------------------------------------
Weighted Average Maturity                                                      21.23 years


TYPES OF RISK

The basic types of risk that the funds face are described below.

Interest Rate Risk


Generally, interest rates and the prices of debt securities move in opposite
directions. When interest rates fall, the prices of most debt securities rise;
when interest rates rise, prices fall. Because the funds invest primarily in
debt securities, changes in interest rates will affect the funds' performance.
This sensitivity to interest rate changes is called interest rate risk.

The degree to which interest rate changes affect the funds' performance varies
and is related to the weighted average maturity of a particular fund. For
example, when interest rates rise, you can expect the share value of a long-term
bond fund to fall more than that of a short-term bond fund. When rates fall, the
opposite is true.

When interest rates change, longer maturity bonds generally experience a greater
change in price. The following table shows the likely effect of a 1% increase in
interest rates on the price of 7% coupon bonds of differing maturities:

REMAINING MATURITY   CURRENT PRICE   PRICE AFTER 1% INCREASE   CHANGE IN PRICE

10 years             $100.00         $93.20                     -6.80%
---------------------------------------------------------------------------------
30 years             $100.00         $88.69                    -11.31%

Credit Risk

Credit risk is the risk that an obligation won't be paid and a loss will result.
A high credit rating indicates a high degree of confidence by the rating
organization that the issuer will be able to withstand adverse business,
financial or economic conditions and be able to make interest and principal
payments on time. Generally, a lower credit rating indicates a greater risk of
non-payment. A lower rating also may indicate that the issuer has a more senior
series of debt securities, which means that if the issuer has difficulties
making its payments, the more senior series of debt is first in line for
payment.


The fund managers do not invest solely on the basis of a security's credit
rating; they also consider other factors, including potential returns. Higher
credit ratings usually mean lower interest rate payments, so the managers often
purchase securities that aren't the highest rated to increase return. If a fund
purchases lower-rated securities, it has assumed additional credit risk.


The following chart shows the authorized credit quality ranges for the funds
offered by this Prospectus.

-------------------------------------------------------------     -----------------------------------------


Securities rated in one of the highest four categories by a nationally
recognized securities rating organization (e.g., Moody's or Standard & Poor's)
are considered investment grade. Although they are considered investment grade,
an investment in these securities still involves some credit risk because a AAA
rating is not a guarantee of payment. For a complete description of the ratings
system, see EXPLANATION OF FIXED-INCOME SECURITIES RATINGS in the Statement of
Additional Information. The funds' credit quality restrictions apply at the time
of purchase; the fund will not necessarily sell securities if they are
downgraded by a rating agency.


Liquidity Risk

Debt securities can become difficult to sell, or less liquid, for a variety of
reasons, such as lack of an active trading market. The chance that a fund will
have liquidity issues is called liquidity risk.

MANAGEMENT

WHO MANAGES THE FUNDS?

The Board of Trustees, investment advisor and fund management team play key
roles in the management of the funds.

THE BOARD OF TRUSTEES

The Board of Trustees oversees the management of the funds and meets at least
quarterly to review reports about fund operations. Although the Board of
Trustees does not manage the funds, it has hired an investment advisor to do so.
More than two-thirds of the trustees are independent of the funds' advisor; that
is, they are not employed by and have no financial interest in the advisor.

THE INVESTMENT ADVISOR


The funds' investment advisor is American Century Investment Management, Inc.
The advisor has been managing mutual funds since 1958 and is headquartered at
4500 Main Street, Kansas City, Missouri 64111.


The advisor is responsible for managing the investment portfolios of the funds
and directing the purchase and sale of their investment securities. The advisor
also arranges for transfer agency, custody and all other services necessary for
the funds to operate.


For the services it provided to the funds during their most recent fiscal year,
the advisor received a unified management fee based on a percentage of the
average net assets of the Investor Class shares of the funds. The rate of the
management fee for each fund is determined monthly on a class-by-class basis
using a two-step formula that takes into account the fund's strategy (money
market, bond or equity) and the total amount of mutual fund assets the advisor
manages.

The Statement of Additional Information contains detailed information about the
calculation of the management fee. Out of that fee, the advisor paid all
expenses of managing and operating the funds except brokerage expenses, taxes,
interest, fees and expenses of the independent trustees (including legal counsel
fees), and extraordinary expenses. A portion of the management fee may be paid
by the funds' advisor to unaffiliated third parties who provide recordkeeping
and administrative services that would otherwise be performed by an affiliate of
the advisor.

MANAGEMENT FEES PAID BY THE FUNDS TO THE ADVISOR AS A PERCENTAGE OF AVERAGE NET
ASSETS FOR THE FISCAL YEAR ENDED MAY 31, 2000

(1)  THE FUNDS IN THIS PROSPECTUS ARE NOT AVAILABLE FOR RETIREMENT ACCOUNTS.

REDEMPTION OF SHARES IN LOW-BALANCE ACCOUNTS

If your redemption activity causes your account balance to fall below the
minimum initial investment amount we will notify you and give you 90 days to
meet the minimum. If you do not meet the deadline, American Century will redeem
the shares in the account and send the proceeds to your address of record.

ABUSIVE TRADING PRACTICES

We do not permit market timing or other abusive trading practices in our funds.

Excessive, short-term (market timing) or other abusive trading practices may
disrupt portfolio management strategies and harm fund performance. To minimize
harm to the funds and their shareholders, we reserve the right to reject any
purchase order (including exchanges) from any investor we believe has a history
of abusive trading or whose trading, in our judgment, has been or may be
disruptive to a fund. In making this judgment, we may consider trading done in
multiple accounts under common ownership or control. We also reserve the right
to delay delivery of your redemption proceeds--up to seven days--or to honor
certain redemptions with securities, rather than cash, as described in the next
section.

SPECIAL REQUIREMENTS FOR LARGE REDEMPTIONS


If, during any 90-day period, you redeem fund shares worth more than $250,000
(or 1% of the assets of the fund if that percentage is less than $250,000), we
reserve the right to pay part or all of the redemption proceeds in excess of
this amount in readily marketable securities instead of in cash. These
securities would be selected from the fund's portfolio by the fund managers. A
payment in securities can help the fund's remaining shareholders avoid tax
liabilities that they might otherwise have incurred had the fund sold securities
prematurely to pay the entire redemption amount in cash.

We will value these securities in the same manner as we do in computing the
fund's net asset value. We may provide these securities in lieu of cash without
prior notice. Also, if payment is made in securities, a shareholder may have to
pay brokerage or other transaction costs to convert the securities to cash.


If your redemption would exceed this limit and you would like to avoid being
paid in securities, please provide us with an unconditional instruction to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur. The instruction  must specify the dollar amount or number of shares to
be redeemed and the date of  the transaction. This minimizes the effect of the
redemption on the fund and its remaining shareholders.

INVESTING THROUGH FINANCIAL INTERMEDIARIES


If you do business with us through a financial intermediary, your ability to
purchase, exchange and redeem shares will depend on the policies of that entity.
Some policy differences may include


*  minimum investment requirements

*  exchange policies

*  fund choices

*  cutoff time for investments


Please contact your financial intermediary for a complete description of its
policies. Copies of the funds' annual reports, semiannual reports and Statement
of Additional Information are available from your intermediary or plan sponsor.


Certain financial intermediaries perform recordkeeping and administrative
services for their clients that would otherwise be performed by American
Century's transfer agent. In some circumstances, American Century will pay the
service provider a fee for performing those services.

Although transactions in fund shares may be made directly with American Century
at no charge, you also may purchase, redeem and exchange fund shares through
financial intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the intermediary and are not shared with
American Century or the funds.

American Century has contracts with certain financial intermediaries requiring
them to track the time investment orders are received and to comply with
procedures relating to the transmission of orders. The funds have authorized
those intermediaries to accept orders on each fund's behalf up to the time at
which the net asset value is determined. If those orders are transmitted to
American Century and paid for in accordance with the contract, they will be
priced at the net asset value next determined after your request is received in
the form required by the intermediary on a fund's behalf.

SHARE PRICE AND DISTRIBUTIONS

SHARE PRICE


American Century determines the NET ASSET VALUE (NAV) of each fund as of the
close of regular trading on the New York Stock Exchange (usually 4 p.m. Eastern
time) on each day the Exchange is open. On days when the Exchange is closed
(including certain U.S. holidays), we do not calculate the NAV. The NAV of a
fund share is the current value of the fund's assets, minus any liabilities,
divided by the number of fund shares outstanding.

If current market prices of securities owned by a fund (except Tax-Free Money
Market) are not readily available, the advisor may determine their fair value in
accordance with procedures adopted by the fund's Board of Trustees. The
portfolio securities of Tax-Free Money Market are valued at amortized cost. This
means that the securities are initially valued at their cost when purchased.
After the initial purchase, the difference between the purchase price and the
known value at maturity will be reduced at a constant rate until maturity. This
valuation will be used regardless of the impact of interest rates on the market
value of the security. The board has adopted procedures to ensure that this type
of pricing is fair to the fund's shareholders.


We will price your purchase, exchange or redemption at the net asset value next
determined after we receive your transaction request in good order.

DISTRIBUTIONS


Federal tax laws require each fund to make distributions to its shareholders in
order to qualify as a regulated investment company. Qualification as a regulated
investment company means that the funds will not be subject to state or federal
income tax on amounts distributed. The distributions generally consist of
dividends and interest received, as well as CAPITAL GAINS realized on the sale
of investment securities.

Tax-Free Money Market declares and pays distributions from net income daily.
Each of the other funds declares distributions from net income daily and pays
these distributions monthly. Each fund (except Tax-Free Money Market) generally
pays distributions of capital gains, if any, once a year usually in December. A
fund may make more frequent distributions, if necessary, to comply with Internal
Revenue Code provisions.

You will participate in fund distributions, when they are declared, starting on
the day after your purchase is effective. For example, if you purchase shares on
a day that a distribution is declared, you will not receive that distribution.
If you redeem shares, you will receive any distribution declared on the day you
redeem. If you redeem all shares, we will include any distributions received
with your redemption proceeds.

Participants in employer-sponsored retirement or savings plans must reinvest all
distributions. For shareholders investing through taxable accounts, we will
reinvest distributions in additional shares unless you elect to receive them in
cash. Please consult your services guide for further information regarding
distributions and your distribution options.


[left margin]

THE NET ASSET VALUE OF A FUND IS THE PRICE OF THE FUND'S SHARES.

CAPITAL GAINS ARE INCREASES IN THE VALUES OF CAPITAL ASSETS, SUCH AS STOCK, FROM
THE TIME THE ASSETS ARE PURCHASED. TAX BECOMES DUE ON CAPITAL GAINS ONCE AN
ASSET IS SOLD.


         www.americancentury.com             American Century Investments   21


TAXES

Tax-Exempt Income

Most of the income that the funds receive from municipal securities is exempt
from  regular federal income taxes. However, corporate shareholders should be
aware that  distributions may be subject to state corporate franchise tax.


The funds also may purchase private activity bonds. The income from these
securities is subject to the federal alternative minimum tax. If you are subject
to the alternative minimum tax, then distributions from the funds that represent
income derived from private activity bonds are taxable to you. Consult your tax
advisor to determine whether you are subject to the alternative minimum tax.


Taxable Income

The funds' investment performance also is based on sources other than income
from municipal securities. These investment performance sources, while not the
primary source of fund distributions, will generate taxable income to you. Some
of these investment performance sources are

*  MARKET DISCOUNT PURCHASES. The funds may buy a tax-exempt security for a
   price less than the principal amount of the bond. If the price of the bond
   increases over time, a portion of the gain may be treated as ordinary income
   and taxable as ordinary income if it is distributed to shareholders.

*  CAPITAL GAINS. When a fund sells a security, even a tax-exempt municipal
   security, it can generate a capital gain or loss, which you must report on
   your tax return.

*  TEMPORARY INVESTMENTS. Some temporary investments, such as securities loans
   and repurchase agreements, can generate taxable income.

TYPE OF DISTRIBUTION        TAX RATE FOR 15% BRACKET   TAX RATE FOR 28% BRACKET
                                                       OR ABOVE
--------------------------------------------------------------------------------
Short-term capital gains    Ordinary income rate       Ordinary income rate
--------------------------------------------------------------------------------
Long-term capital gains     10%                        20%


The tax status of any distribution of capital gains is determined by how long a
fund held the underlying security that was sold, not by how long you have been
invested in the fund or whether you reinvest your distribution in additional
shares or take them in cash. For taxable accounts, American Century will inform
you of the tax status of fund distributions for each calendar year in an annual
tax mailing (Form 1099-DIV).


Distributions also may be subject to state and local taxes. Because everyone's
tax  situation is unique, always consult your tax professional about federal,
state and local  tax consequences.

[graphic of pointing finger]
BUYING A DIVIDEND

PURCHASING FUND SHARES IN A TAXABLE ACCOUNT SHORTLY BEFORE A DISTRIBUTION IS
SOMETIMES KNOWN AS BUYING A DIVIDEND. IN TAXABLE ACCOUNTS, YOU MUST PAY INCOME
TAXES ON THE DISTRIBUTION WHETHER YOU REINVEST THE DISTRIBUTION OR TAKE IT IN
CASH. IN ADDITION, YOU WILL HAVE TO PAY TAXES ON THE DISTRIBUTION WHETHER THE
VALUE OF YOUR INVESTMENT DECREASED, INCREASED OR REMAINED THE SAME AFTER YOU
BOUGHT THE FUND SHARES.

THE RISK IN BUYING A DIVIDEND IS THAT A FUND'S PORTFOLIO MAY BUILD UP TAXABLE
GAINS THROUGHOUT THE PERIOD COVERED BY A DISTRIBUTION, AS SECURITIES ARE SOLD AT
A PROFIT. WE DISTRIBUTE THOSE GAINS TO YOU, AFTER SUBTRACTING ANY LOSSES, EVEN
IF YOU DID NOT OWN THE SHARES WHEN THE GAINS OCCURRED.

IF YOU BUY A DIVIDEND, YOU INCUR THE FULL TAX LIABILITY OF THE DISTRIBUTION
PERIOD, BUT YOU MAY NOT ENJOY THE FULL BENEFIT OF THE GAINS REALIZED IN THE
FUND'S PORTFOLIO.

Taxes on Transactions


Your redemptions--including exchanges to other American Century funds--are
subject to capital gains tax. The table above can provide a general guide for
your potential tax liability when selling or exchanging fund shares. Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares decrease in value, their sale or exchange will result in a long-term or
short-term capital loss. However, you should note that loss realized upon the
sale or exchange of shares held for six months or less will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain to you with respect to those shares. Also, any loss realized upon the sale
or exchange of shares held for six months or less will be disallowed to the
extent of any distribution  of tax-exempt income to you with respect to such
shares. If a loss is realized on the redemption of fund shares, the reinvestment
in additional fund shares within 30 days before or after the redemption may be
subject to the wash sale rules of the Internal Revenue Code. This may result in
a postponement of the recognition of such loss for federal income tax purposes.

If you have not certified to us that your Social Security number or tax
identification number is correct and that you are not subject to 31%
withholding, we are required to withhold and pay 31% of dividends distributions,
capital gains distributions and redemptions to the IRS.

FINANCIAL HIGHLIGHTS

UNDERSTANDING THE FINANCIAL HIGHLIGHTS


The tables on the next few pages itemize what contributed to the changes in
share price during the most recent fiscal year end. They also show the changes
in share price for this period in comparison to changes over the last five
fiscal years or less, if the fund is not five years old.


On a per-share basis, each table includes as appropriate

*  share price at the beginning of the period

*  investment income and capital gains or losses

*  distributions of income and capital gains paid to shareholders

*  share price at the end of the period

Each table also includes some key statistics for the period as appropriate


*  TOTAL RETURN - the overall percentage of return of the fund, assuming the
   reinvestment of all distributions

*  EXPENSE RATIO - operating expenses as a percentage of average net assets

*  NET INCOME RATIO - net investment income as a percentage of average net
   assets

*  PORTFOLIO TURNOVER - the percentage of the fund's buying and selling activit

The Financial Highlights for the fiscal years ended May 31, 2000, 1999 and 1998,
have been audited by PricewaterhouseCoopers LLP, independent accountants. Their
report is included in the funds' annual reports, which are incorporated by
reference into the Statement of Additional Information, and are available upon
request. Prior years' information was audited by other independent auditors,
whose report also is incorporated by reference into the Statement of Additional
Information.

Throughout this Statement of Additional Information we refer to American Century
Municipal Trust as the Trust.

Each fund described in this Statement of Additional Information is a separate
series of the Trust and operates for many purposes as if it were an independent
company. Each fund has its own investment objective, strategy, management team,
assets, tax identification and stock registration number.

FUND INVESTMENT GUIDELINES


This section explains the extent to which the funds' advisor, American Century
Investment Management, Inc., can use various investment vehicles and strategies
in managing a fund's assets. Descriptions of the investment techniques and risks
associated with each appear in the section, Investment Strategies and Risks,
which begins on page 6. In the case of the funds' principal investment
strategies, these descriptions elaborate upon discussions contained in the
Prospectuses.

Each fund (except High-Yield Municipal, Florida Municipal Money Market, Florida
Intermediate-Term Municipal and Arizona Intermediate-Term Municipal) is a
diversified open-end investment company as defined in the Investment Company Act
of 1940 (the Investment Company Act). Diversified means that, with respect to
75% of its total assets, each fund will not invest more than 5% of its total
assets in the securities of a single issuer or own more than 10% of the
outstanding voting securities of a single issuer.

Tax-Free Money Market and Florida Municipal Money Market each operate pursuant
to Rule 2a-7 under the Investment Company Act. That rule permits the valuation
of portfolio securities on the basis of amortized cost. To rely on the rule,
each of these funds must be diversified with regard to 100% of its assets other
than U.S. government securities. This operating policy is more restrictive than
the Investment Company Act, which requires a diversified investment company to
be diversified with regard to only 75% of its assets.

To meet federal tax requirements for qualification as a regulated investment
company, each fund must limit its investments so that at the close of each
quarter of its taxable  year (1) no more than 25% of its total assets are
invested in the securities of a single issuer (other than the U.S government or
a regulated investment company), and (2) with respect to at least 50% of its
total assets, no more than 5% of its total assets are invested in the securities
of a single issuer (other than the U.S government or a regulated investment
company) or it does not own more than 10% of the outstanding voting securities
of a single issuer.


In general, within the restrictions outlined here and in the funds'
Prospectuses, the fund managers have broad powers to decide how to invest fund
assets, including the power to hold them uninvested.


2       American Century Investments                             1-800-345-2021


So long as a sufficient number of acceptable securities are available, the fund
managers intend to keep the funds fully invested. However, under exceptional
conditions, the funds may assume a defensive position, temporarily investing all
or a substantial portion of their assets in cash or short-term securities.


For an explanation of the securities ratings referred to in the Prospectus and
this Statement of Additional Information, see Explanation of Fixed-Income
Securities Ratings beginning on page 38.


FLORIDA MUNICIPAL MONEY MARKET FUND
FLORIDA INTERMEDIATE-TERM MUNICIPAL FUND

The Florida Municipal Money Market Fund and Florida Intermediate-Term Municipal
Fund seek to obtain as high a level of current income exempt from regular
federal income tax as is consistent with prudent investment management and
conservation of shareholders' capital. In addition, fund shares are intended to
be exempt from the Florida Intangibles Tax.

The funds are designed for individuals in upper tax brackets seeking income free
from regular federal income tax, although the funds may generate some taxable
income. The funds also provide an investment that is intended to be exempt from
the Florida Intangibles Tax. Because of this emphasis on tax-exempt income, the
funds by themselves do not constitute a balanced investment plan.


Each fund intends to remain fully invested in municipal obligations (obligations
issued by or on behalf of a state, its political subdivisions, agencies, and
instrumentalities). As a fundamental policy, each fund will invest at least 80%
of its net assets in obligations with interest exempt from federal and Florida
state income tax. The funds are not limited, however, in their investments in
securities that are subject to the Federal Alternative Minimum Tax (AMT).

In addition, each fund will invest at least 65% of its net assets in Florida
municipal obligations (obligations issued by or on behalf of Florida, its
political subdivisions, agencies and instrumentalities). The funds sometime
invest in obligations of the Commonwealth of Puerto Rico and its public
corporations (as well as the U.S. territories of Guam and the Virgin Islands)
that are exempt from federal and Florida state income taxes. The remaining 35%
of each fund's net assets may be invested in (1) obligations issued by other
states and their political subdivisions and (2) U.S. government securities.


Each fund is authorized under normal conditions to invest as much as 100% of its
net assets in municipal obligations for which the interest is a tax preference
item for purposes of the AMT. If you are or become subject to the AMT, a portion
of your income distributions that are exempt from the regular federal income tax
may not be exempt from the AMT. Interest from AMT bonds is considered to be
exempt from federal income tax purposes of the 80% policy noted above.

A fund may need to sell certain investments near the end of each calendar year
so that on January 1 of each year, its portfolio consists only of investments
that are exempt from the Florida Intangibles Tax. As a result, a fund could
incur additional costs or taxable income or gains.

ARIZONA INTERMEDIATE-TERM MUNICIPAL FUND

Arizona Intermediate-Term Municipal seeks to obtain as high a level of current
income exempt from Arizona and regular federal income tax as is consistent with
prudent investment management and conservation of shareholders' capital.

Arizona Intermediate-Term Municipal is designed for individuals in upper tax
brackets seeking income free from Arizona state and regular federal income
taxes, although the fund may generate some taxable income. Because of this
emphasis on tax-exempt income, the fund does not constitute a balanced
investment.

In addition, Arizona Intermediate-Term Municipal will invest at least 65% of its
net assets in Arizona municipal obligations (obligations issued by or on behalf
of Arizona or its political subdivisions, agencies and instrumentalities). The
fund sometimes invests in obligations of the Commonwealth of Puerto Rico and its
public corporations (as well as the U.S. territories of Guam and the Virgin

TAX-FREE MONEY MARKET FUND
LIMITED-TERM TAX-FREE FUND
INTERMEDIATE-TERM
TAX-FREE FUND
LONG-TERM TAX-FREE FUND


Tax-Free Money Market Fund, Limited-Term Tax-Free Fund, Intermediate-Term
Tax-Free Fund and Long-Term Tax-Free Fund seek as high a level of current income
exempt from regular federal income tax as is consistent with prudent investment
management and conservation of shareholders' capital.


Each fund intends to remain fully invested in municipal obligations, although
for temporary defensive purposes, each may invest a portion of its assets in
U.S. government securities, the interest income on which is subject to federal
income tax. The municipal obligations in which the funds may invest include
securities issued by U.S. territories or possessions, such as Puerto Rico,
provided that the interest on these securities is exempt from regular federal
income tax.

The funds may invest up to 20% of their total assets in municipal obligations
for which the interest is a tax preference item for purposes of the AMT.

HIGH-YIELD MUNICIPAL FUND

High-Yield Municipal Fund seeks to provide high current income exempt from
federal income tax as is consistent with its investment policies, which permit
investment in lower-rated and unrated securities. As a secondary objective, the
fund seeks capital appreciation.

The fund intends to remain fully invested in municipal obligations (obligations
issued by or on behalf of a state or its political subdivisions, agencies and
instrumentalities). The fund also may invest in securities issued by U.S.
territories or possessions, such as Puerto Rico, provided that the interest on
these securities is exempt from regular federal income tax. As a fundamental
policy, the fund will invest at least 80% of its net assets in obligations with
interest exempt from regular federal income tax. The fund is not limited,
however, in its investments in securities that are subject to the AMT.

The fund is authorized, under normal conditions, to invest as much as 100% of
its net assets in municipal obligations for which the interest is a tax
preference item for purposes of the AMT. If you are or become subject to the
AMT, a portion of your income distributions that are exempt from regular federal
income tax may not be exempt from the AMT.

The fund intends to remain fully invested in municipal obligations, although for
temporary defensive purposes, it may invest a portion of its assets in U.S.
government securities, the interest income on which is subject to federal income

CREDIT QUALITY AND MATURITY GUIDELINES

The Money Market Funds

Tax-Free Money Market Fund and Florida Municipal Money Market Fund seek to
maintain a $1.00 share price, although there is no guarantee they will be able
to do so. Shares of the funds are neither insured nor guaranteed by the U.S.
government.

The money market funds may be appropriate for investors seeking share price
stability who can accept the lower yields that short-term obligations typically
provide.

In selecting investments for the money market funds, the advisor adheres to
regulatory guidelines concerning the quality and maturity of money market fund
investments as well as to internal guidelines designed to minimize credit risk.
In particular, each fund:


*  buys only U.S. dollar-denominated obligations with remaining maturities of 13
   months or less (and variable- and floating-rate obligations with demand
   features that effectively shorten their maturities to 13 months or less);

*  maintains a dollar-weighted average portfolio maturity of 90 days or less;

*  restricts its investments to high-quality obligations determined by the
   advisor pursuant to guidelines established by the Board of Trustees to
   present minimal credit risks.

To be considered high-quality, an obligation must be:

*  a U.S. government obligation; or

*  rated (or of an issuer rated with respect to a class of short-term
   obligations), within the two highest rating categories for short-term debt
   obligations by at least two nationally recognized statistical rating agencies
   (or one if only one has rated the obligation); or

*  an unrated obligation judged by the advisor, pursuant to guidelines
   established by the Board of Trustees, to be of quality comparable to the
   securities listed above.

The fund managers intend to buy only obligations that are designated as
first-tier securities as defined by the SEC; that is, securities rated, when
acquired, within the highest category designated by a rating agency.


The acquisition of securities that are unrated or rated by only one rating
agency must be approved or ratified by the Board of Trustees.

Non-Money Market Funds (except High-Yield Municipal)

Limited-Term Tax-Free, Intermediate-Term Tax-Free, Long-Term Tax-Free, Arizona
Intermediate-Term Municipal and Florida Intermediate-Term Municipal have
identical policies governing the quality of securities in which they may invest.
The funds differ in their maturity criteria as stated in the Prospectus.

In terms of credit quality, each of these funds restricts its investments to


*  municipal bonds rated, when acquired, within the four highest categories
   designated by a rating agency

*  municipal notes (including variable-rate demand obligations) and tax-exempt
   commercial paper rated, when acquired, within the two highest categories
   designated by a rating agency

*  unrated obligations judged by the advisor, under the direction of the Board
   of Trustees, to be of quality comparable to the securities listed above.

High-Yield Municipal

Like the other non-money market funds, High-Yield Municipal invests primarily in
long- and intermediate-term municipal obligations. Although High-Yield Municipal
typically invests a significant portion of its assets in investment-grade bonds,
the advisor does not adhere to specific rating criteria in selecting investments
for this fund. The fund invests in securities rated or judged by the advisor to
be below investment-grade quality (e.g., bonds rated BB/Ba or lower, which are
sometimes referred to as junk bonds) or unrated bonds.

Many issuers of medium- and lower-quality bonds choose not to have their
obligations rated and a large portion of High-Yield's portfolio may consist of
obligations that, when acquired, were not rated. There is no limit to the
percentage of assets that the fund may invest in unrated securities.  The fund
also may invest in securities that are in technical or monetary default.

High-Yield Municipal may invest in investment-grade municipal obligations if the
advisor considers it appropriate to do so. Investments of this nature may be
made due to market considerations (e.g., a limited supply of medium- and
lower-grade municipal obligations) or to increase liquidity of the fund.
Investing in high-grade obligations may lower the fund's return.

High-Yield Municipal may purchase private activity municipal securities. The
interest from these securities is treated as a tax-preference item in
calculating federal AMT liability. Under normal circumstances, it is possible
that a substantial portion of the fund's total assets will be invested in
private activity securities. Therefore, the fund is better suited for investors
who do not expect alternative minimum tax liability. See Taxes, page 33.

FUND INVESTMENTS AND RISKS


INVESTMENT STRATEGIES AND RISKS


This section describes investment vehicles and strategies that the fund managers
can use in managing a fund's assets. It also details the risks associated with
each, because each technique contributes to a fund's overall risk profile.


Concentration in Types of Municipal Activities

From time to time, a significant portion of a fund's assets may be invested in
municipal obligations that are related to the extent that economic, business or
political developments affecting one of these obligations could affect the other
obligations in a similar manner. For example, if a fund invested a significant
portion of its assets in utility bonds and a state or federal government agency
or legislative body promulgated or enacted new environmental protection
requirements for utility providers, projects financed by utility bonds could
suffer as a group. Additional financing might be required to comply with the new
environmental requirements, and outstanding debt might be downgraded in the
interim. Among other factors that could negatively affect bonds issued to
finance similar types of projects are state and federal legislation regarding
financing for municipal projects, pending court decisions relating to the
validity or means of financing municipal projects, material or manpower
shortages and declining demand for projects or facilities financed by the
municipal bonds.

About the Risks Affecting Arizona Municipal Securities

As noted in the Prospectus, the Arizona Intermediate-Term Municipal Fund is
susceptible to events that affect issuers of Arizona municipal obligations.
These include possible adverse affects of Arizona constitutional amendments,
legislative measures, voter initiatives and other matters described below.


6       American Century Investments                            1-800-345-2021


The following information about risk factors is provided in view of the fund's
policy of concentrating its assets in Arizona municipal securities. This
information is based on certain official statements of the state of Arizona
published in connection with the issuance of specific Arizona municipal
securities as well as from other publicly available sources. It does not
constitute a complete description of the risks associated with investing in
securities of these issuers. While the advisor has not independently verified
the information contained in the official statements, it has no reason to
believe the information is inaccurate.


Located in the country's sunbelt, Arizona's population has been, and is
projected to continue to be, one of the fastest growing in the United States.
Over the last several decades, the state has outpaced most other regions of the
country in population and personal income growth, gross state product and job
creation.

Geographically, Arizona is the nation's sixth largest state in terms of area. It
is divided into three distinct topographic regions: the northern third, which is
high plateau country traversed by deep canyons, such as Grand Canyon National
Park; central Arizona, which is rugged, mountainous and heavily forested; and
the southern third, which encompasses desert areas and flat, fertile
agricultural lands in valleys between mountains rich in mineral deposits. These
topographic areas all have different climates, which have distinctively
influenced development in each region.

The Phoenix metropolitan area is the state's primary economic center as it
represents approximately two-thirds of the state's population. The Tucson area,
while of secondary importance, also is a major economic area in the state.

The Arizona economy continues to diversify away from its historical reliance on
the mining and agricultural employment sectors. Significant job growth has
occurred in the areas of aerospace and high technology, construction, finance,
insurance and real estate. Arizona's economy has continued to grow in recent
years, as it is among the fastest growing economies in the nation.


Under its constitution, the state of Arizona is not permitted to issue general
obligation bonds secured by the full faith and credit of the state. However,
certain agencies and instrumentalities of the state are authorized to issue
bonds secured by revenues from specific projects and activities, and the state
and local governmental units may enter into lease transactions. The particular
source of payments and security for an Arizona municipal obligation is detailed
in the instruments themselves and in related offering materials.

The state and local governmental units are subject to limitations imposed by
Arizona law with respect to ad valorem taxation, bonded indebtedness, the amount
of annual increases in taxes, and other matters. These limitations may affect
the ability of the issuers to generate revenues to satisfy their debt
obligations. There are periodic attempts in the form of voter initiatives and
legislative proposals to further limit the amount of annual increases in taxes
that may be levied without voter approval. If such a proposal were enacted,
there might be an adverse impact on state or local government financing.

Arizona is required by law to maintain a balanced budget. In the past, the state
has used a combination of spending reductions and tax increases to avoid
potential budgetary shortfalls and may be required to do so again in the future.


On July 8, 1998, the Arizona state legislature passed and its governor signed,
legislation that shifts the funding of public education from local governments
to the state. This was done in response to a state supreme court decision
requiring the state to deliver and implement a more equitable funding of public
education. The impact of this on the state's finances in the long term is
uncertain.

A potential long-term credit concern for all states is the impact of eCommerce
on tax collections. The use of the internet to make retail purchases (eCommerce
spending) is projected to increase rapidly over the next few years.  According
to Forrester Research, eCommerce spending amounted to approximately $7.8 billion
in 1998 and is projected to



www.americancentury.com                       American Century Investment      7



reach $184 billion in 2004. The proliferation of eCommerce spending could
potentially impact municipal credit quality because eCommerce spending is exempt
from sales taxes. The most vulnerable bonds would be credits secured solely by
sales tax revenues.


About the Risks Affecting Florida Municipal Securities

As noted in the Prospectus, the Florida Municipal Money Market and Florida
Intermediate-Term Municipal funds are susceptible to events that affect issuers
of Florida municipal obligations. These include possible adverse affects of
Florida constitutional amendments, legislative measures, voter initiatives and
other matters described below.

The following information about risk factors is provided in view of the funds'
policies of concentrating their assets in Florida municipal securities. This
information is based on independent municipal credit reports relating to
securities offerings of Florida issuers and other publicly available sources. It
does not constitute a complete description of the risks associated with
investing in securities of these issuers. While the advisor has not
independently verified this information, it has no reason to believe the
information is inaccurate.


Because the funds invest primarily in Florida municipal securities, they will be
affected by political and economic conditions and developments within the state
of Florida. In general, the credit quality and credit risk of any issuer's debt
depend on the state and local economy, the health of the issuer's finances, the
amount of the issuer's debt, the quality of management and the strength of legal
provisions in debt documents that protect debt holders. Credit risk is usually
lower whenever the economy is strong, growing and diversified, financial
operations are sound, and the debt burden is reasonable.

The state of Florida's economy is characterized by a large service sector, a
dependence on the tourism and construction industries and a large retirement
population. The management of rapid growth has been the major challenge facing
state and local governments. Florida's population has grown rapidly and it is
now the fourth largest state; this growth is expected to continue, but at
reduced rates. The retiree component is expected to continue to be a major
factor. As this growth continues, the demand for both public and private
services will increase, which may strain the service sector's capacity and
impede the state's budget balancing efforts. For example, school districts have
experienced difficulty in funding school construction as the districts have been
unable to obtain voter approval to issue debt to finance the necessary school
construction.

One of the fastest growing states, Florida's economy has centered on the growing
trade and services industry, further influenced by tourism and agriculture. The
state is outperforming the nation in employment and income growth. Florida ranks
twentieth among all states in personal per capita income, with a 1998 per capita
income that is about 98% of the U.S figure.

Florida continues to experience steady job growth. Non-farm payroll employment
growth of about 4% for 1997 through 1999 exceeds national rates for those years,
and approximates the record growth rates of earlier periods in 1993 and 1994.
Preliminary employment figures for 2000 indicate continued growth at higher than
national rates. Tourism, one of the main drivers of the state's economy, is
predicted to continue to grow in fiscal 2000. The state projects total tourist
arrivals for 2000 at about 51 million, a 5% increase over 1999.


Debt levels in the state of Florida are moderate to high, reflecting the
tremendous capital demands associated with rapid population growth. Florida is
unusual among states in that all general obligation full faith and credit debt
issues of municipalities must be approved by public referendum and are,
therefore, relatively rare. Most debt instruments issued by local municipalities
and authorities have a narrower pledge of security, such as a sales tax stream,
special assessment revenue, user fees, utility taxes or fuel taxes. Credit
quality of such debt instruments tends to be somewhat lower than that of general
obliga-


8        American Century Investments                           1-800-345-2021


tion debt. The state of Florida issues general obligation debt for a variety of
purposes; however, the state constitution requires a specific revenue stream to
be pledged to state general obligation bonds as well.


The state of Florida is heavily dependent upon sales tax, which makes the
state's general fund vulnerable to recession. This dependence upon sales tax,
combined with economic recession, has resulted in budgetary shortfalls in the
past. Florida has reacted to preserve an adequate financial position primarily
through expenditure reductions. State officials, however, still face tremendous
capital and operating pressures due to the growth that will continue to strain
the state's narrow revenue base. As a counterbalance to the dependence on the
historically volatile sales tax, the state enacted a constitutional amendment
establishing a Budget Stabilization Fund and has since made yearly deposits to
that Fund. At the end of fiscal 1999, the Fund reached $787 million, meeting the
required minimum fund level of 5% of General Fund revenues by 1999. The state
plans on an additional deposit of $60 million in 2000, bringing the fiscal 2000
balance to $847 million.

The state also has established a constitutional state revenue limitation to
restrain the growth of spending. To date, this cap has not yet posed a
constraint. The cap, which became effective in fiscal 1996, limits the amount of
taxes and other revenues that could be raised by the state in any fiscal year.
It allows annual revenue to grow by the average annual growth in personal income
over the previous five years. Exempted from the cap are revenues that are
directly pledged to bonds, including any new debt issuances. The cap does not
appear to have become a major impediment to the state raising sufficient annual
revenue to fund state expenditure growth. The legislature may increase the
revenue cap by a two-thirds vote of each house.

A potential long-term credit concern for all states is the impact of eCommerce
on tax collections. The use of the internet to make retail purchases (eCommerce
spending) is projected to increase rapidly over the next few years.  According
to Forrester Research, eCommerce spending amounted to approximately $7.8 billion
in 1998 and is projected to reach $184 billion in 2004. The proliferation of
eCommerce spending could potentially impact municipal credit quality since
eCommerce spending is exempt from sales taxes. The most vulnerable bonds would
be credits secured solely by sales tax revenues.


About the Risks Affecting Puerto Rico Municipal Securities


From time to time, the funds invest in obligations of the Commonwealth of Puerto
Rico and its public corporations, which are exempt from federal, state and city
or local income taxes. The majority of the Commonwealth's debt is issued by the
major public agencies that are responsible for many of the island's public
functions, such as water, wastewater, highways, telecommunications, education
and public construction. As of December 31, 1999, public sector debt issued by
the Commonwealth and its public corporations totaled $22.8 billion.

Since the 1980s, Puerto Rico's economy and financial operations have paralleled
the economic cycles of the United States. The island's economy, particularly the
manufacturing sector, has experienced substantial gains in employment. Much of
these economic gains have been attributable in part to favorable treatment under
Section 936 of the federal Internal Revenue Code for U.S. corporations doing
business in Puerto Rico (see discussion below). The number of persons employed
in Puerto Rico during fiscal 1999 averaged more than 1.1 million. Unemployment,
however, still remains high at 11.9% as of January 2000.

Debt ratios for the Commonwealth are high as it assumes much of the
responsibility for local infrastructure. Sizable infrastructure programs are
ongoing to upgrade the island's water, sewer and road systems. The
Commonwealth's general obligation debt is secured by a first lien on all
available revenues. The Commonwealth seeks to correlate the growth in public
sector debt to the growth of the economic base available to service that debt.



www.americancentury.com                   American Century Investments        9



However, due to the financing of certain key infrastructure projects, between
fiscal years 1996 and 1999, debt increased 28.7% while gross product rose 25.9%.

The maximum annual debt service requirement on Commonwealth general obligation
debt totaled 9.5% of governmental revenues for fiscal 1999. This is well below
the 15% limit imposed by the Constitution of Puerto Rico.

The current ratio of tax-supported debt to aggregate personal income is almost
48%, about twenty times the average level of the fifty states, and more than
four times as high as the most heavily indebted of the states. The ratio is
affected by the low levels of income in Puerto Rico (per capita income is about
one-third the U.S. average) and by the large absolute amount of debt.

Puerto Rico's financial position has been adequate. Strong tax growth was offset
by spending increases for health, public education and debt service. After
drawing down cash for several years, fiscal year 1998 ended with a sizable
surplus resulting in an increase in cash from 2.4% of revenues in fiscal year
1997 to 5.6% of revenues in fiscal year 1998. This was primarily attributable to
several non-recurring revenue items. Preliminary fiscal year 1999 results
indicate that cash will be drawn down to 3.5% of revenues with an additional
drawdown expected in fiscal year 2000.

As a result of 1995 federal legislation, tax credits provided by Section 936 of
the Internal Revenue Code are being phased out over a ten-year period ending in
tax year 2005. Section 936 has offered an important economic development
incentive for Puerto Rico, providing a particular impetus for the manufacturing
sector. For U.S. corporations doing business in Puerto Rico, Section 936
generally eliminated the U.S. tax on income related to their island operations.
It granted these corporations tax credits to offset federal tax liability on
earnings from Puerto Rico operations (active income) and permitted them to
invest such earnings in qualified investments in Puerto Rico (passive income)
with interest earned free from U.S. tax. As a result of the 1996 legislation,
the active income credit has been reduced and is no longer available to new or
expanded operations in Puerto Rico. It will also be phased out entirely after
tax year 2005. The passive income credit has already been eliminated entirely.

To offset the loss of the 936 tax credit, in 1998, the Commonwealth passed the
Tax Incentives Law that provided for various tax reduction/incentives. While
this law may promote development, it must be balanced by the costs of the
development in terms of lost tax dollars. The danger Puerto Rico faces is being
too generous with tax incentives, whereby, government revenues are negatively
impacted by development incentives.

Another long-term issue, with broad implications for the Commonwealth, is the
question of political status - specifically, the potential for a transition to
statehood, as contemplated by proposed federal legislation in 1999 and the
subject of a non-binding plebiscite in Puerto Rico in December 1998. The
statehood option in the 1998 plebiscite received the support of 45.6% of the
voters, about the same percentage of support in the previous plebiscite in 1993.

A final risk factor with the Commonwealth is the large amount of unfunded
pension liabilities. The two main public pension systems are largely
underfunded. The combined funded ratio of the two plans is 35% with a total
unfunded liability of $7 billion. A measure enacted by the legislature in 1990
is designed to address the solvency of the plans over a 50-year period.

A potential long-term credit concern for all states is the impact of eCommerce
on tax collections. The use of the internet to make retail purchases (eCommerce
spending) is projected to increase rapidly over the next few years. According to
Forrester Research, eCommerce spending amounted to approximately $7.8 billion in
1998 and is projected to reach $184 billion in 2004. The proliferation of
eCommerce spending could potentially impact municipal credit quality since
eCommerce spending is exempt from sales taxes. The most vulnerable bonds would
be credits secured solely by sales tax revenues.

Municipal Notes

Municipal notes are issued by state and local governments or government entities
to provide short-term capital or to meet cash flow needs.


Tax anticipation notes (TANs) are issued in anticipation of seasonal tax
revenues, such as ad valorem property, income, sales, use and business taxes,
and are payable from these future taxes. Tax anticipation notes usually are
general obligations of the issuer. General obligations are secured by the
issuer's pledge of its full faith and credit (i.e., taxing power) for the
payment of principal and interest.

Revenue anticipation notes (RANs) are issued with the expectation that receipt
of future revenues, such as federal revenue sharing or state aid payments, will
be used to repay the notes. Typically, these notes also constitute general
obligations of the issuer.

Bond anticipation notes (BANs) are issued to provide interim financing until
long-term financing can be arranged. In most cases, the long-term bonds provide
the money for repayment of the notes.

Tax-exempt commercial paper is an obligation with a stated maturity of 365 days
or less issued to finance seasonal cash flow needs or to provide short-term
financing in anticipation of longer-term financing.

Revenue anticipation warrants, or reimbursement warrants, are issued to meet the
cash flow needs of state governments at the end of a fiscal year and in the
early weeks of the following fiscal year. These warrants are payable from
unapplied money in the state's General Fund, including the proceeds of revenue
anticipation notes issued following enactment of a state budget or the proceeds
of refunding warrants issued by the state.


Municipal Bonds


Municipal bonds, which generally have maturities of more than one year when
issued, are designed to meet longer-term capital needs. These securities have
two principal classifications: general obligation bonds and revenue bonds.

General obligation (GO) bonds are issued by states, counties, cities, towns and
regional districts to fund a variety of public projects, including construction
of and improvements to schools, highways, and water and sewer systems. GO bonds
are backed by the issuer's full faith and credit based on its ability to levy
taxes for the timely payment of interest and repayment of principal, although
such levies may be constitutionally or statutorily limited as to rate or amount.

Revenue bonds are not backed by an issuer's taxing authority; rather, interest
and principal are secured by the net revenues from a project or facility.
Revenue bonds are issued to finance a variety of capital projects, including
construction or refurbishment of utility and waste disposal systems, highways,
bridges, tunnels, air and sea port facilities, schools and hospitals. Many
revenue bond issuers provide additional security in the form of a debt-service
reserve fund that may be used to make payments of interest and repayments of
principal on the issuer's obligations. Some revenue bond financings are further
protected by a state's assurance (without obligation) that it will make up
deficiencies in the debt-service reserve fund.

Industrial development bonds (IDBs), a type of revenue bond, are issued by or on
behalf of public authorities to finance privately operated facilities. These
bonds are used to finance business, manufacturing, housing, athletic and
pollution control projects, as well as public facilities such as mass transit
systems, air and sea port facilities and parking garages. Payment of interest
and repayment of principal on an IDB depend solely on the ability of the
facility's user to meet financial obligations, and on the pledge, if any, of the
real or personal property financed. The interest earned on IDBs may be subject
to the federal alternative minimum tax.

Variable- and Floating-Rate Obligations


Variable- and floating-rate demand obligations (VRDOs and FRDOs) carry rights
that permit holders to demand payment of the unpaid principal plus accrued
interest, from the issuers or from financial intermediaries. Floating-rate
securities, or floaters, have interest rates that change whenever there is a
change in a designated base rate. Variable-rate instruments provide for a
specified, periodic adjustment in the interest rate, which typically is based on
an index. These rate formulas are designed to result in a market value for the
VRDO or FRDO that approximates par value.


Obligations with Term Puts Attached


Fixed-rate bonds subject to third-party puts and participation interests in such
bonds held by a bank in trust or otherwise have tender options or demand
features that permit the funds to tender (or put) their bonds to an institution
at periodic intervals and to receive the principal amount thereof.


The advisor expects that the funds will pay more for securities with puts
attached than for securities without these liquidity features. The advisor may
buy securities with puts attached to keep a fund fully invested in municipal
securities while maintaining sufficient portfolio liquidity to meet redemption
requests or to facilitate management of the fund's investments.

To ensure that the interest on municipal securities subject to puts is
tax-exempt to the funds, the advisor limits the funds' use of puts in accordance
with applicable interpretations and rulings of the Internal Revenue Service
(IRS).

Because it is difficult to evaluate the likelihood of exercise or the potential
benefit of a put, puts normally will be determined to have a value of zero,
regardless of whether any direct or indirect consideration is paid. Accordingly,
puts as separate securities are not expected to affect the funds' weighted
average maturities. When a fund has paid for a put, the cost will be reflected
as unrealized depreciation on the underlying security for the period the put is
held. Any gain on the sale of the underlying security will be reduced by the
cost of the put.

There is a risk that the seller of a put will not be able to repurchase the
underlying obligation when (or if) a fund attempts to exercise the put. To
minimize such risks, the funds will purchase obligations with puts attached only
from sellers deemed creditworthy by the advisor under the direction of the Board
of Trustees.

Tender Option Bonds


Tender option bonds (TOBs) were created to increase the supply of high-quality,
short-term tax-exempt obligations, and thus they are of particular interest to
the money market funds. However, any of the funds may purchase these
instruments.


TOBs are created by municipal bond dealers who purchase long-term, tax-exempt
bonds in the secondary market, place the certificates in trusts, and sell
interests in the trusts with puts or other liquidity guarantees attached. The
credit quality of the resulting synthetic short-term instrument is based on the
guarantor's short-term rating and the underlying bond's long-term rating.

There is some risk that the put agreement on a tender option agreement will
terminate if the underlying bond is downgraded or defaults. Because of this, the
advisor monitors the credit quality of bonds underlying the funds' TOB holdings
and intends to sell or put back any TOB if the rating on its underlying bond
falls below the second-highest rating category designated by a rating agency.


The advisor also takes steps to minimize the risk that a fund may realize
taxable income as a result of holding TOBs. These steps may include
consideration of (1) legal opinions relating to the tax-exempt status of the
underlying municipal bonds, (2) legal opinions



12          American Century Investments                         1-800-345-2021


relating to the tax ownership of the underlying bonds, and (3) other elements of
the structure that could result in taxable income or other adverse tax
consequences. After purchase, the advisor monitors factors related to the
tax-exempt status of the fund's TOB holdings in order to minimize the risk of
generating taxable income.

When-Issued and Forward Commitment Agreements

The funds may engage in municipal securities transactions on a when-issued or
forward commitment basis in which the transaction price and yield are each fixed
at the time the commitment is made, but payment and delivery occur at a future
date (typically 15 to 45 days later).

When purchasing securities on a when-issued or forward commitment basis, a fund
assumes the rights and risks of ownership, including the risks of price and
yield fluctuations. While the fund will make commitments to purchase or sell
securities with the intention of actually receiving or delivering them, it may
sell the securities before the settlement date if doing so is deemed advisable
as a matter of investment strategy.

In purchasing securities on a when-issued or forward commitment basis, a fund
will establish and maintain until the settlement date a segregated account
consisting of cash, cash equivalents or other appropriate liquid securities in
an amount sufficient to meet the purchase price. When the time comes to pay for
the when-issued securities, the fund will meet its obligations with available
cash, through the sale of securities, or, although it would not normally expect
to do so, by selling the when-issued securities themselves (which may have a
market value greater or less than the fund's payment obligation). Selling
securities to meet when-issued or forward commitment obligations may generate
taxable capital gains or losses.

As an operating policy, no fund will commit more than 50% of its total assets to
when-issued or forward commitment agreements. If fluctuations in the value of
securities held cause more than 50% of a fund's total assets to be committed
under when-issued or forward commitment agreements, the fund managers need not
sell such agreements, but it will be restricted from entering into further
agreements on behalf of the fund until the percentage of assets committed to
such agreements is below 50% of total assets.

Municipal Lease Obligations

Each fund may invest in municipal lease obligations. These obligations, which
may take the form of a lease, an installment purchase, or a conditional sale
contract, are issued by state and local governments and authorities to acquire
land and a wide variety of equipment and facilities. Generally, the funds will
not hold such obligations directly as a lessor of the property but will purchase
a participation interest in a municipal lease obligation from a bank or other
third party.

Municipal leases frequently carry risks distinct from those associated with
general obligation or revenue bonds. State constitutions and statutes set
requirements that states and municipalities must meet to incur debt. These may
include voter referenda, interest rate limits or public sale requirements.
Leases, installment purchases or conditional sale contracts (which normally
provide for title to the leased asset to pass to the government issuer) have
evolved as a way for government issuers to acquire property and equipment
without meeting constitutional and statutory requirements for the issuance of
debt.

Many leases and contracts include nonappropriation clauses, which provide that
the governmental issuer has no obligation to make future payments under the
lease or contract unless money is appropriated for such purposes by the
appropriate legislative body on a yearly or other periodic basis. Municipal
lease obligations also may be subject to abatement risk. For example,
construction delays or destruction of a facility as a result of an uninsurable
disaster that prevents occupancy could result in all or a portion of a lease
payment not being made.

Inverse Floaters

The funds (except the money market funds) may hold inverse floaters. An inverse
floater is a type of derivative that bears an interest rate that moves inversely
to market interest rates. As market interest rates rise, the interest rate on
inverse floaters goes down, and vice versa. Generally, this is accomplished by
expressing the interest rate on the inverse floater as an above-market fixed
rate of interest, reduced by an amount determined by reference to a market-based
or bond-specific floating interest rate (as well as by any fees associated with
administering the inverse floater program).


Inverse floaters may be issued in conjunction with an equal amount of Dutch
Auction floating-rate bonds (floaters), or a market-based index may be used to
set the interest rate on these securities. A Dutch Auction is an auction system
in which the price of the security is gradually lowered until it meets a
responsive bid and is sold. Floaters and inverse floaters may be brought to
market (1) by a broker-dealer who purchases fixed-rate bonds and places them in
a trust or (2) by an issuer seeking to reduce interest expenses by using a
floater/inverse floater structure in lieu of fixed-rate bonds.


In the case of a broker-dealer structured offering (where underlying fixed-rate
bonds have been placed in a trust), distributions from the underlying bonds are
allocated to floater and inverse floater holders in the following manner:


*  Floater holders receive interest based on rates set at a six-month interval
   or at a Dutch Auction, which is typically held every 28 to 35 days. Current
   and prospective floater holders bid the minimum interest rate that they are
   willing to accept on the floaters, and the interest rate is set just high
   enough to ensure that all of the floaters are sold.

*  Inverse floater holders receive all of the interest that remains on the
   underlying bonds after floater interest and auction fees are paid.


Procedures for determining the interest payment on floaters and inverse floaters
brought to market directly by the issuer are comparable, although the interest
paid on the inverse floaters is based on a presumed coupon rate that would have
been required to bring fixed-rate bonds to market at the time the floaters and
inverse floaters were issued.

Where inverse floaters are issued in conjunction with floaters, inverse floater
holders may be given the right to acquire the underlying security (or to create
a fixed-rate bond) by calling an equal amount of corresponding floaters. The
underlying security may then be held or sold. However, typically, there are time
constraints and other limitations associated with any right to combine interests
and claim the underlying security.

Floater holders subject to a Dutch Auction procedure generally do not have the
right to "put back" their interests to the issuer or to a third party. If a
Dutch Auction fails, the floater holder may be required to hold its position
until the underlying bond matures, during which time interest on the floater is
capped at a predetermined rate.

The secondary market for floaters and inverse floaters may be limited. The
market value of inverse floaters tends to be significantly more volatile than
fixed-rate bonds. The interest rates on inverse floaters may be significantly
reduced, even to zero, if interest rates rise.

Lower-Quality Bonds

As indicated in the Prospectus, an investment in High-Yield Municipal carries
greater risk than an investment in the other funds because the fund may invest
without limitation in lower-rated bonds and unrated bonds judged by the advisor
to be of comparable quality (collectively, lower-quality bonds).

While the market values of higher-quality bonds tend to correspond to market
interest rate changes, the market values of lower-quality bonds tend to reflect
the financial condition of their issuers.


14        American Century Investments                           1-800-345-2021


Projects financed through the issuance of lower-quality bonds are often highly
leveraged. The issuer's ability to service its debt obligations may be adversely
affected by an economic downturn, a period of rising interest rates, the
issuer's inability to meet projected revenue forecasts, or a lack of needed
additional financing.

Lower-quality bonds generally are unsecured and often are subordinated to other
obligations of the issuer. These bonds frequently have call or buy-back features
that permit the issuer to call or repurchase the bond from the holder. Premature
disposition of a lower-quality bond due to a call or buy-back feature,
deterioration of the issuer's creditworthiness, or a default may make it
difficult for the advisor to manage the flow of income to the fund, which may
have negative tax implications for shareholders.

The market for lower-quality bonds tends to be concentrated among a smaller
number of dealers than the market for higher-quality bonds. This market is
dominated by dealers and institutions (including mutual funds), rather than by
individuals. To the extent that a secondary trading market for lower-quality
bonds exists, it may not be as liquid as the secondary market for higher-quality
bonds. Limited liquidity in the secondary market may adversely affect market
prices and hinder the advisor's ability to dispose of particular bonds when it
determines that it is in the best interest of the fund to do so. Reduced
liquidity also may hinder the advisor's ability to obtain market quotations for
purposes of valuing the fund's portfolio and determining its net asset value.

The advisor continually monitors securities to determine their relative
liquidity.

A fund may incur expenses in excess of its ordinary operating expenses if it
becomes necessary to seek recovery on a defaulted bond, particularly a
lower-quality bond.

Repurchase Agreements


Each fund may invest in repurchase agreements when they present an attractive
short-term return on cash that is not otherwise committed to the purchase of
securities pursuant to the investment policies of that fund.


A repurchase agreement occurs when, at the time the fund purchases an
interest-bearing obligation, the seller (a bank or a broker-dealer registered
under the Securities Exchange Act of 1934) agrees to purchase it on a specified
date in the future at an agreed-upon price. The repurchase price reflects an
agreed-upon interest rate during the time the fund's money is invested in the
security.

Because the security purchased constitutes security for the repurchase
obligation, a repurchase agreement can be considered a loan collateralized by
the security purchased. The fund's risk is the ability of the seller to pay the
agreed-upon repurchase price on the repurchase date. If the seller defaults, the
fund may incur costs in disposing of the collateral, which would reduce the
amount realized thereon. If the seller seeks relief under the bankruptcy laws,
the disposition of the collateral may be delayed or limited. To the extent the
value of the security decreases, the fund could experience a loss.


The funds will limit repurchase agreement transactions to securities issued by
the U.S. government and its agencies and instrumentalities, and will enter into
such transactions with those banks and securities dealers who are deemed
creditworthy by the funds' advisor.

No fund will invest more than 15% of its assets in repurchase agreements
maturing in more than seven days and other illiquid securities.


Short-Term Securities


In order to meet anticipated redemptions, to hold pending the purchase of
additional securities for a fund's portfolio, or, in some cases, for temporary
defensive purposes, the non-money market funds may invest a portion of their
assets in money market and other short-term securities.



www.americancentury.com                   American Century Investments       15



Examples of those securities include:

*  Securities issued or guaranteed by the U.S. government and its agencies and
   instrumentalities

*  Commercial Paper

*  Certificates of Deposit and Euro Dollar Certificates of Deposit

*  Bankers' Acceptances

*  Short-term notes, bonds, debentures or other debt instruments

*  Repurchase agreements

Under the Investment Company Act, a fund's investment in other investment
companies (including money market funds) currently is limited to (a) 3% of the
total voting stock of any one investment company; (b) 5% of the fund's total
assets with respect to any one investment company; and (c) 10% of a fund's total
assets in the aggregate. For the non-money market funds, these investments may
include investments in money market funds managed by the advisor. Any
investments in money market funds must be consistent with the investment
policies and restrictions of the fund making the investment.


Futures and Options

Each non-money market fund may enter into futures contracts, options or options
on futures contracts. Some futures and options strategies, such as selling
futures, buying puts and writing calls, hedge a fund's investments against price
fluctuations. Other strategies, such as buying futures, writing puts and buying
calls, tend to increase market exposure. The funds do not use futures and
options transactions for speculative purposes.

Although other techniques may be used to control a fund's exposure to market
fluctuations, the use of futures contracts may be a more effective means of
hedging this exposure. While a fund pays brokerage commissions in connection
with opening and closing out futures positions, these costs are lower than the
transaction costs incurred in the purchase and sale of the underlying
securities.

Futures contracts provide for the sale by one party and purchase by another
party of a specific security at a specified future time and price. Futures
contracts are traded on national futures exchanges. Futures exchanges and
trading are regulated under the Commodity Exchange Act by the Commodity Futures
Trading Commission (CFTC), a U.S. government agency. The funds may engage in
futures and options transactions based on securities indexes such as the Bond
Buyer Index of Municipal Bonds that are consistent with the fund's investment
objectives. The fund also may engage in futures and options transactions based
on specific securities such as U.S. Treasury bonds or notes.

Bond Buyer Municipal Bond Index futures contracts differ from traditional
futures contracts in that when delivery takes place, no bonds change hands.
Instead, these contracts settle in cash at the spot market value of the Bond
Buyer Municipal Bond Index.

Although other types of futures contracts by their terms call for actual
delivery or acceptance of the underlying securities, in most cases the contracts
are closed out before the settlement date. A futures position may be closed by
taking an opposite position in an identical contract (i.e., buying a contract
that has previously been sold or selling a contract that has previously been
bought).

To initiate and maintain open positions in a futures contract, a fund would be
required to make a good faith margin deposit in cash or government securities
with a futures broker or custodian. A margin deposit is intended to assure
completion of the contract (delivery or acceptance of the underlying security)
if it is not terminated prior to the specified delivery date. Minimum initial
margin requirements are established by the futures exchanges and may be revised.
In addition, brokers may establish margin deposit requirements that are higher
than the exchange minimums.


16        American Century Investments                           1-800-345-2021


Once a futures contract position is opened, the value of the contract is marked
to market daily. If the futures contract price changes to the extent that the
margin on deposit does not satisfy margin requirements, the contract holder is
required to pay additional variation margin. Conversely, changes in the contract
value may reduce the required margin, resulting in a repayment of excess margin
to the contract holder. Variation margin payments are made to or from the
futures broker for as long as the contract remains open and do not constitute
margin transactions for purposes of the funds' investment restrictions.

RISKS RELATED TO FUTURES AND OPTIONS TRANSACTIONS

Futures and options prices can be volatile, and trading in these markets
involves certain risks. If the advisor applies a hedge at an inappropriate time
or judges interest rate trends incorrectly, futures and options strategies may
lower a fund's return.

A fund could suffer losses if it were unable to close out its position because
of an illiquid secondary market. Futures contracts may be closed out only on an
exchange that provides a secondary market for these contracts, and there is no
assurance that a liquid secondary market will exist for any particular futures
contract at any particular time. Consequently, it may not be possible to close a
futures position when the advisor considers it appropriate or desirable to do
so. In the event of adverse price movements, a fund would be required to
continue making daily cash payments to maintain its required margin. If the fund
had insufficient cash, it might have to sell portfolio securities to meet daily
margin requirements at a time when the advisor would not otherwise elect to do
so. In addition, a fund may be required to deliver or take delivery of
instruments underlying futures contracts it holds. The advisor will seek to
minimize these risks by limiting the contracts entered into on behalf of the
funds to those traded on national futures exchanges and for which there appears
to be a liquid secondary market.


A fund could suffer losses if the prices of its futures and options positions
were poorly correlated with its other investments, or if securities underlying
futures contracts purchased by a fund had different maturities than those of the
portfolio securities being hedged. Such imperfect correlation may give rise to
circumstances in which a fund loses money on a futures contract at the same time
that it experiences a decline in the value of its hedged portfolio securities. A
fund also could lose margin payments it has deposited with a margin broker, if,
for example, the broker became bankrupt.


Most futures exchanges limit the amount of fluctuation permitted in futures
contract prices during a single trading day. The daily limit establishes the
maximum amount that the price of a futures contract may vary either up or down
from the previous day's settlement price at the end of the trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price beyond the limit. However, the daily limit
governs only price movement during a particular trading day and, therefore, does
not limit potential losses. In addition, the daily limit may prevent liquidation
of unfavorable positions. Futures contract prices have occasionally moved to the
daily limit for several consecutive trading days with little or no trading,
thereby preventing prompt liquidation of futures positions and subjecting some
futures traders to substantial losses.

OPTIONS ON FUTURES

By purchasing an option on a futures contract, a fund obtains the right, but not
the obligation, to sell the futures contract (a put option) or to buy the
contract (a call option) at a fixed-strike price. A fund can terminate its
position in a put option by allowing it to expire or by exercising the option.
If the option is exercised, the fund completes the sale of the underlying
security at the strike price. Purchasing an option on a futures contract does
not require a fund to make margin payments unless the option is exercised.

Although they do not currently intend to do so, the funds may write (or sell)
call options that obligate it to sell (or deliver) the option's underlying
instrument upon exercise of the option. While the receipt of option premiums
would mitigate the effects of price declines,


www.americancentury.com                American Century Investments           17


the funds would give up some ability to participate in a price increase on the
underlying security. If a fund were to engage in options transactions, it would
own the futures contract at the time a call were written and would keep the
contract open until the obligation to deliver it pursuant to the call expired.

RESTRICTIONS ON THE USE OF FUTURES CONTRACTS AND OPTIONS

Each non-money market fund may enter into futures contracts, options or options
on futures contracts.


Under the Commodity Exchange Act, a fund may enter into futures and options
transactions (a) for hedging purposes without regard to the percentage of assets
committed to initial margin and option premiums or (b) for other than hedging
purposes, provided that assets committed to initial margin and option premiums
do not exceed 5% of the fund's total assets. To the extent required by law, each
fund will set aside cash and appropriate liquid assets in a segregated account
to cover its obligations related to futures contracts and options.


Restricted and Illiquid Securities


The funds may, from time to time, purchase restricted or illiquid securities,
including Rule 144A securities, when they present attractive investment
opportunities that otherwise meet the funds' criteria for selection. Rule 144A
securities are securities that are privately placed with and traded among
qualified institutional investors rather than the general public. Although Rule
144A securities are considered restricted securities, they are not necessarily
illiquid.


With respect to securities eligible for resale under Rule 144A, the staff of the
SEC has taken the position that the liquidity of such securities in the
portfolio of a fund offering redeemable securities is a question of fact for the
Board of Trustees to determine, such determination to be based upon a
consideration of the readily available trading markets and the review of any
contractual restrictions. Accordingly, the Board of Trustees is responsible for
developing and establishing the guidelines and procedures for determining the
liquidity of Rule 144A securities. As allowed by Rule 144A, the Board of
Trustees of the funds has delegated the day-to-day function of determining the
liquidity of Rule 144A securities to the advisor. The Board retains the
responsibility to monitor the implementation of the guidelines and procedures it
has adopted.

Because the secondary market for such securities is limited to certain qualified
institutional investors, the liquidity of such securities may be limited
accordingly and a fund may, from time to time, hold a Rule 144A or other
security that is illiquid. In such an event, the advisor will consider
appropriate remedies to minimize the effect on such fund's liquidity.

INVESTMENT POLICIES


Unless otherwise indicated, with the exception of the percentage limitations on
borrowing, the restrictions described below apply at the time a fund enters into
a transaction. Accordingly, any later increase or decrease beyond the specified
limitation resulting from a change in a fund's net assets will not be considered
in determining whether it has complied with its investment restrictions.


Fundamental Investment Policies


The funds' fundamental investment restrictions are set forth below. These
investment restrictions may not be changed without approval of a majority of the
outstanding votes of shareholders of a fund, as determined in accordance with
the Investment Company Act.

                   acquired as a result of ownership of securities or other
                   instruments, provided that this limitation shall not prohibit
                   the fund from purchasing or selling options and futures
                   contracts or from investing in securities or other
                   instruments backed by physical commodities.
--------------------------------------------------------------------------------
Control            A fund may not invest for purposes of exercising control over
                   management.
--------------------------------------------------------------------------------

For purposes of the investment restrictions relating to lending and borrowing,
the funds have received an exemptive order from the SEC regarding interfund
lending. Under the terms of the exemptive order, the funds may borrow money from
or lend money to other funds, advised by ACIM, that permit such transactions.
All such transactions will be subject to the limits set above for borrowing and
lending. The funds will borrow money through the program only when the costs are
equal to or lower than the cost of short-term bank loans. Interfund loans and
borrowings normally extend only overnight, but can have a maximum duration of
seven days. The funds will lend through the program only when the returns are
higher than those available from other short-term instruments (such as
repurchase agreements). The funds may have to borrow from a bank at a higher
interest rate if an interfund loan is called or not renewed. Any delay in
repayment to a lending fund could result in a lost investment opportunity or
additional borrowing costs.


For purposes of the investment restriction relating to concentration, a fund
shall not purchase any securities that would cause 25% or more of the value of
the fund's total assets at the time of purchase to be invested in the securities
of one or more issuers conducting their principal business activities in the
same industry, provided that (a) there is no limitation with respect to
obligations issued or guaranteed by the U.S. government, any state, territory or
possession of the United States, the District of Columbia or any of their
authorities, agencies, instrumentalities or political subdivisions and
repurchase agreements secured by such instruments, (b) wholly owned finance
companies will be considered to be in the industries of their parents if their
activities are primarily related to financing the activities of the parents, (c)
utilities will be divided according to their services; for example, gas, gas
transmission, electric and gas, electric, and telephone will each be considered
a separate industry, and (d) personal credit and business credit businesses will
be considered separate industries.

Nonfundamental Investment Policies


In addition, the funds are subject to the following investment restrictions that
are not fundamental and may be changed by the Board of Trustees.

Subject                   Policy
--------------------------------------------------------------------------------
Leveraging                A fund may not purchase additional investment
[Tax-Free Money Market,   securities at any time during which outstanding
Limited-Term,             borrowings exceed 5% of the total assets of the fund.
Intermediate-Term
and Long-Term Tax-Free]
--------------------------------------------------------------------------------
Futures and options       The money market funds may not purchase or sell
[money market             futures contracts or call options. This limitation
funds only]               does not apply to options attached to, or acquired
                          or traded together with, their underlying
                          securities, and does not apply to securities that
                          incorporate features similar to options
                          or futures contracts.
--------------------------------------------------------------------------------
Liquidity                 A fund may not purchase any security or enter into a
                          Repurchase agreement if, as a result, more than 15%
                          of its net assets (10% for the money market funds)
                          would be invested in illiquid securities. Illiquid
                          securities include repurchase agreements not entitling
                          the holder to payment of principal and interest within
                          seven days and in securities that are illiquid by
                          vittue of legal or contractual restrictions on resale
                          or the absence of a readily available market.
--------------------------------------------------------------------------------
Short Sales               A fund may not sell securities short, unless it owns
                          or has the right to obtain securities equivalent in
                          kind and amount to the securities sold short, and
                          provided that transactions in futures contracts and
                          options are not deemed to constitute selling
                          securities short.
--------------------------------------------------------------------------------
Margin                    A fund may not purchase securities on margin, except
                          to obtain such short-term credits as are necessary for
                          the clearance of transactions, and provided that
                          margin payments in connection with futures contracts
                          and options on futures contracts shall not constitute
                          purchasing securities on margin.
--------------------------------------------------------------------------------


TEMPORARY DEFENSIVE MEASURES

For temporary defensive purposes, a fund may invest in securities that may not
fit its investment objective or its stated market. During a temporary defensive
period, a fund may direct its assets to the following investment vehicles:


(1) interest-bearing bank accounts or Certificates of Deposit;


(2) U.S. government securities and repurchase agreements collateralized by U.S.
    government securities; and

(3) other money market funds.

PORTFOLIO TURNOVER


Under normal conditions, the funds' annual portfolio turnover rates are not
expected to exceed 100%. Because a higher turnover rate increases transaction
costs and may increase taxable capital gains, the funds' managers carefully
weigh the potential benefits of short-term investing against these
considerations.


The funds' portfolio turnover rates (except those of the money market funds) are
listed in the Financial Highlights table in the Prospectuses. Because of the
short-term nature of the money market funds' investments, portfolio turnover
rates are not generally used to evaluate their trading activities.

MANAGEMENT

THE BOARD OF TRUSTEES


The Board of Trustees oversees the management of the funds and meets at least
quarterly to review reports about fund operations. Although the Board of
Trustees does not manage the funds, it has hired the advisor to do so.
Two-thirds of the trustees are independent of the funds' advisor; that is, they
are not employed by and have no financial interest in the advisor.

The individuals listed in the table below whose names are marked by an asterisk
(*) are interested persons of the funds (as defined in the Investment Company
Act) by virtue of, among other considerations, their affiliation with either the
funds; their advisor, American Century Investment Management, Inc. (ACIM); the
funds' agent for transfer and administrative services, American Century Services
Corporation (ACSC); the parent corporation, American Century Companies, Inc.
(ACC) or ACC's subsidiaries (including ACIM and ACSC); the funds' distribution
agent, Funds Distributor, Inc.; and the funds' other distribution agent,
American Century Investment Services, Inc. (ACIS); or other funds advised by the
advisor. Each trustee (except James E. Stowers III) listed below serves as a
trustee or director of six other registered investment companies in the American
Century family of funds, which are also advised by the advisor. James E. Stowers
III serves as a trustee or director of 12 other registered investment companies
in the American Century family of funds.

COMPENSATION OF TRUSTEES


The trustees also serve as trustees for six American Century investment
companies other than American Century Municipal Trust. Each trustee who is not
an interested person as defined in the Investment Company Act receives
compensation for service as a member of the board of all seven such companies
based on a schedule that takes into account the number of meetings attended and
the assets of the funds for which the meetings are held. These fees and expenses
are divided among the seven investment companies based, in part, upon their
relative net assets. Under the terms of the management agreement with the
advisor, the funds are responsible for paying such fees and expenses.

The following table shows the aggregate compensation paid by the Trust for the
periods indicated and by the seven investment companies served by this board to
each trustee who is not an interested person as defined in the Investment
Company Act.

(1) Includes compensation paid to the trustees during the fiscal year ended May
    31, 2000, and also includes amounts deferred at the election of the trustees
    under the Amended and Restated American Century Mutual Funds Deferred
    Compensation Plan for Non-Interested Directors. The total amount of deferred
    compensation included in the preceding table is as follows: Mr. Eisenstat,
    $6,489; Mr. Gilson, $6,683; Mr. Scholes, $6,404; and Mr. Scott, $3,336.

(2) Includes compensation paid by the seven investment company members of the
    American Century family of funds served by this board.

(3) Mr. Stein retired from the board on September 15, 2000.

The funds have adopted the Amended and Restated American Century Mutual Funds
Deferred Compensation Plan for Non-Interested Directors. Under the plan, the
independent trustees may defer receipt of all or any part of the fees to be paid
to them for serving as trustees of the funds.


All deferred fees are credited to an account established in the name of the
trustees. The amounts credited to the account then increase or decrease, as the
case may be, in accordance with the performance of one or more of the American
Century funds that are selected by the trustee. The account balance continues to
fluctuate in accordance with the performance of the selected fund or funds until
final payment of all amounts are credited to the account. Trustees are allowed
to change their designation of mutual funds from time to time.


No deferred fees are payable until such time as a trustee resigns, retires or
otherwise ceases to be a member of the Board of Trustees. Trustees may receive
deferred fee account balances either in a lump-sum payment or in substantially
equal installment payments to be made over a period not to exceed 10 years. Upon
the death of a trustee, all remaining deferred fee account balances are paid to
the trustee's beneficiary or, if none, to the trustee's estate.

The plan is an unfunded plan and, accordingly, the funds have no obligation to
segregate assets to secure or fund the deferred fees. To date, the funds have
voluntarily funded their obligations. The rights of trustees to receive their
deferred fee account balances are the same as the rights of a general unsecured
creditor of the funds. The plan may be terminated at any time by the
administrative committee of the plan. If terminated, all deferred fee account
balances will be paid in a lump sum.

No deferred fees were paid to any trustee under the plan during the fiscal year
ended May 31, 2000.

The funds are unaware of any other shareholders, beneficial or of record, who
own more than 5% of any class of a fund's outstanding shares. As of September 1,
2000, the officers and trustees of the funds, as a group, owned less than 1% of
any class of a fund's outstanding shares.


SERVICE PROVIDERS

The funds have no employees. To conduct the funds' day-to-day activities, the
funds have hired a number of service providers. Each service provider has a
specific function to fill on behalf of the funds and is described below.


ACIM, ACSC and ACIS are wholly owned by ACC. James E. Stowers, Jr., Chairman of
ACC, controls ACC by virtue of his ownership of a majority of its voting stock.


INVESTMENT ADVISOR


A description of the responsibilities of the advisor appears in the Prospectus
under the heading Management.

For the services provided to the funds, the advisor receives a monthly fee based
on a percentage of the average net assets of a fund. The annual rate at which
this fee is assessed is determined monthly in a two-step process. First, a fee
rate schedule is applied to the assets of all the funds of its investment
category managed by the advisor (the Investment Category Fee). For example, when
calculating the fee for a money market fund, all the assets of the money market
funds managed by the advisor are aggregated. The three investment categories are
money market funds, bond funds and equity funds. Second, a separate fee rate
schedule is applied to the assets of all the funds managed by the advisor (the
Complex Fee). The Investment Category Fee and the Complex Fee are then added to
determine the unified management fee payable by a fund to the advisor.

On the first business day of each month, the funds pay a management fee to the
advisor for the previous month at the specified rate. The fee for the previous
month is calculated by multiplying the applicable fee for the fund by the
aggregate average daily closing value of a fund's net assets during the previous
month. This number is then multiplied by a fraction, the numerator of which is
the number of days in the previous month and the denominator of which is 365
(366 in leap years).


The management agreement between the Trust and the advisor shall continue in
effect until the earlier of the expiration of two years from the date of its
execution or until the first meeting of shareholders following such execution
and for as long thereafter as its continuance is specifically approved at least
annually, by (1) the funds' Board of Trustees, or by the vote of a majority of
outstanding votes (as defined in the Investment Company Act) and (2) by the vote
of a majority of the trustees of the funds who are not parties to the agreement
or interested persons of the advisor, cast in person at a meeting called for the
purpose of voting on such approval.


The management agreement provides that it may be terminated at any time without
payment of any penalty by the funds' Board of Trustees, or by a vote of a
majority of outstanding votes, on 60 days' written notice to the advisor, and
that it shall be automatically terminated if it is assigned.


The management agreement states that the advisor shall not be liable to the
funds or their shareholders for anything other than willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations and duties. The
management agreement also provides that the advisor and its officers, trustees
and employees may engage in other business, devote time and attention to any
other business whether of a similar or dissimilar nature, and render services to
others.


Certain investments may be appropriate for the funds and also for other clients
advised by the advisor. Investment decisions for the funds and other clients are
made with a view to achieving their respective investment objectives after
consideration of such factors as their current holdings, availability of cash
for investment and the size of their investment generally. A particular security
may be bought or sold for only one client or fund, or in different amounts and
at different times for more than one but less than all clients or funds. In
addition, purchases or sales of the same security may be made for two or more
clients or funds on the same date. Such transactions will be allocated among
clients in a manner believed by the advisor to be equitable to each. In some
cases this procedure could have an adverse effect on the price or amount of the
securities purchased or sold  by a fund.


The advisor may aggregate purchase and sale orders of the funds with purchase
and sale orders of its other clients when the advisor believes that such
aggregation provides the best execution for the funds. The Board of Trustees has
approved the policy of the advisor with respect to the aggregation of portfolio
transactions. Where portfolio transactions have been aggregated, the funds
participate at the average share price for all transactions in that security on
a given day and share transaction costs on a pro rata basis. The advisor will
not aggregate portfolio transactions of the funds unless it believes that such
aggregation is consistent with its duty to seek best execution on behalf of the
funds and the terms of the management agreement. The advisor receives no
additional compensation or remuneration as a result of such aggregation.


Prior to August 1, 1997, Benham Management Corporation served as the investment
advisor to the funds. Benham Management Corporation was merged into the advisor
in late 1997.


Unified management fees paid by each fund for the fiscal periods ended May 31,
2000, 1999, and 1998, are indicated in the following tables.

OTHER SERVICE PROVIDERS

CUSTODIAN BANKS


Chase Manhattan Bank, 770 Broadway, 10th floor, New York, New York 10003-9598,
and Commerce Bank, N.A., 1000 Walnut, Kansas City, Missouri 64105, each serve as
custodian of the assets of the funds. The custodians take no part in determining
the investment policies of the funds or deciding which securities are purchased
or sold by the funds. The funds, however, may invest in certain obligations of
the custodians and may purchase or sell certain securities from or to the
custodians.

INDEPENDENT ACCOUNTANTS

PricewaterhouseCoopers LLP are the independent accountants of the funds. The
address of PricewaterhouseCoopers LLP is 1055 Broadway, 10th floor, Kansas City,
Missouri 64105. As the independent accountants of the funds,
PricewaterhouseCoopers provides services including (1) audit of the annual
financial statements for each fund, (2) assistance and consultation in
connection with SEC filings, and (3) review of the annual federal income tax
return filed for each fund.

BROKERAGE ALLOCATION


The fund generally purchases and sells debt securities through principal
transactions, meaning the funds normally purchase securities directly from the
issuer or a primary market-maker acting as principal for the securities on a net
basis. The funds do not pay brokerage commissions on these transactions,
although the purchase price for debt securities usually includes an undisclosed
compensation. Purchases from underwriters or securities typically include a
commission or concession paid by the issuer to the underwriter, and purchases
from dealers serving as market-makers typically include a dealer's mark-up
(i.e., a spread between the bid and asked prices). During the fiscal years ended
May 31, 1998, 1999 and 2000, the funds did not pay any brokerage commissions.


INFORMATION ABOUT FUND SHARES

Each of the funds named on the front of this Statement of Additional Information
is a series of shares issued by the Trust, and shares of each fund have equal
voting rights.

Each fund votes separately on matters affecting that fund exclusively. Voting
rights are not cumulative, so that investors holding more than 50% of the
Trust's (i.e., all funds') outstanding shares may be able to elect a Board of
Trustees. The Trust undertakes dollar-based voting, meaning that the number of
votes a shareholder is entitled to is based upon the dollar amount of the
shareholder's investment. The election of trustees is determined by the votes
received from all Trust shareholders without regard to whether a majority of
shares of any one fund voted in favor of a particular nominee or all nominees as
a group.


Each shareholder has rights to dividends and distributions declared by the fund
he or she owns and to the net assets of such fund upon its liquidation or
dissolution proportionate to his or her share ownership interest in the fund.


Shareholders of a Massachusetts business trust could, under certain
circumstances, be held personally liable for its obligations. However, the
Declaration of Trust contains an express disclaimer of shareholder liability for
acts or obligations of the Trust. The Declaration of Trust also provides for
indemnification and reimbursement of expenses of any shareholder held personally
liable for obligations of the Trust. The Declaration of Trust provides that the
Trust will, upon request, assume the defense of any claim made against any
shareholder for any act or obligation of the Trust and satisfy any judgment
thereon. The Declaration of Trust further provides that the Trust may maintain
appropriate insurance (for example, fidelity, bonding and errors and omissions
insurance) for the protection of the Trust, its shareholders, trustees,
officers, employees and agents to cover possible tort and other liabilities.
Thus, the risk of a shareholder incurring financial loss as a result of
shareholder liability is limited to circumstances in which both inadequate
insurance exists and the Trust is unable to meet its obligations.

BUYING AND SELLING FUND SHARES


Information about buying, selling and exchanging fund shares is contained in the
funds' prospectuses and in Your Guide to American Century Services. The
prospectuses and guide are available to investors without charge and may be
obtained by calling us.

VALUATION OF A FUND'S SECURITIES


Each fund's net asset value per share (NAV) is calculated as of the close of
business of the New York Stock Exchange (the Exchange) each day the Exchange is
open for business. The Exchange usually closes at 4 p.m. Eastern time. The
Exchange typically observes the following holidays: New Year's Day, Martin
Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day. Although the funds expect
the same holidays to be observed in the future, the Exchange may modify its
holiday schedule at any time.


Each fund's NAV is calculated by adding the value of all portfolio securities
and other assets, deducting liabilities and dividing the result by the number of
shares outstanding. Expenses and interest earned on portfolio securities are
accrued daily.

Money Market Funds

Securities held by the money market funds are valued at amortized cost. This
method involves valuing an instrument at its cost and thereafter assuming a
constant amortization to maturity of any discount or premium paid at the time of
purchase. Although this method provides certainty in valuation, it generally
disregards the effect of fluctuating interest rates on an instrument's market
value. Consequently, the instrument's amortized cost value may be higher or
lower than its market value, and this discrepancy may be reflected in the funds'
yields. During periods of declining interest rates, for example, the daily yield
on fund shares computed as described above may be higher than that of a fund
with identical investments priced at market value. The converse would apply in a
period of rising interest rates.

The money market funds operate pursuant to Investment Company Act Rule 2a-7,
which permits valuation of portfolio securities on the basis of amortized cost.
As required by the rule, the Board of Trustees has adopted procedures designed
to stabilize, to the extent reasonably possible, a money market fund's price per
share as computed for the purposes of sales and redemptions at $1.00. While the
day-to-day operation of the money market funds has been delegated to the fund
managers, the quality requirements established by the procedures limit
investments to certain instruments that the Board of Trustees has determined
present minimal credit risks and that have been rated in one of the two highest
rating categories as determined by a rating agency or, in the case of unrated
securities, of comparable quality. The procedures require review of the money
market funds' portfolio holdings at such intervals as are reasonable in light of
current market conditions to determine whether the money market funds' net asset
values calculated by using available market quotations deviate from the
per-share value based on amortized cost. The procedures also prescribe the
action to be taken if such deviation should occur.

The Board of Trustees monitors the levels of illiquid securities, however if the
levels are exceeded, they will take action to rectify these levels.

Actions the Board of Trustees may consider under these circumstances include (i)
selling portfolio securities prior to maturity, (ii) withholding dividends or
distributions from capital, (iii) authorizing a one-time dividend adjustment,
(iv) discounting share purchases and initiating redemptions in kind, or (v)
valuing portfolio securities at market price for purposes of calculating NAV.

Non-Money Market Funds

Securities held by the non-money market funds normally are priced by an
independent pricing service, provided that such prices are believed by the
advisor to reflect the fair market value of portfolio securities.

Because there are hundreds of thousands of municipal issues outstanding, and the
majority of them do not trade daily, the prices provided by pricing services are
generally determined without regard to bid or last sale prices. In valuing
securities, the pricing


32        American Century Investments                           1-800-345-2021


services generally take into account institutional trading activity, trading in
similar groups of securities, and any developments related to specific
securities. The methods used by the pricing service and the valuations so
established are reviewed by the advisor under the general supervision of the
Board of Trustees. There are a number of pricing services available, and the
advisor, on the basis of ongoing evaluation of these services, may use other
pricing services or discontinue the use of any pricing service in whole or in
part.


Securities not priced by a pricing service are valued at the mean between the
most recently quoted bid and ask prices provided by broker-dealers. The
municipal bond market is typically a "dealer market"; that is, dealers buy and
sell bonds for their own accounts rather than for customers. As a result, the
spread, or difference, between bid and asked prices for certain municipal bonds
may differ substantially among dealers.


Debt securities maturing within 60 days of the valuation date may be valued at
cost, plus or minus any amortized discount or premium, unless the trustees
determine that this would not result in fair valuation of a given security.
Other assets and securities for which quotations are not readily available are
valued in good faith at their fair value using methods approved by the Board of
Trustees.

TAXES

FEDERAL INCOME TAX


Each fund intends to qualify annually as a regulated investment company under
Subchapter M of the Internal Revenue Code of 1986, as amended (the Code). By so
qualifying, a fund will be exempt from federal and state income taxes to the
extent that it distributes substantially all of its net investment income and
net realized capital gains (if any) to shareholders. If a fund fails to qualify
as a regulated investment company, it will be liable for taxes, significantly
reducing its distributions to shareholders and eliminating shareholders' ability
to treat distributions of the funds in the manner in which they were realized by
the funds.


Certain of the bonds purchased by the funds may be treated as bonds that were
originally issued at a discount. Original issue discount represents interest for
federal income tax purposes and can generally be defined as the difference
between the price at which a security was issued and its stated redemption price
at maturity. Original issue discount, although no cash is actually received by a
fund until the maturity of the bond, is treated for federal income tax purposes
as income earned by a fund over the term of the bond, and therefore is subject
to the distribution requirements of the Code. The annual amount of income earned
on such a bond by a fund generally is determined on the basis of a constant
yield to maturity that takes into account the semiannual compounding of accrued
interest. Original issue discount on an obligation with interest exempt from
federal income tax will constitute tax-exempt interest income to the fund.


In addition, some of the bonds may be purchased by a fund at a discount that
exceeds the original issue discount on such bonds, if any. This additional
discount represents market discount for federal income tax purposes. The gain
realized on the disposition of any bond having market discount generally will be
treated as taxable ordinary income to the extent it does not exceed the accrued
market discount on such bond (unless a fund elects to include market discount in
income in tax years to which it is attributable). Generally, market discount
accrues on a daily basis for each day the bond is held by a fund on a straight
line basis over the time remaining to the bond's maturity. In the case of any
debt security having a fixed maturity date of not more than one year from date
of issue, the gain realized on disposition generally will be treated as
short-term capital gain. In general, gain realized on disposition of a security
held less than one year is treated as a short-term capital gain.



www.americancentury.com                   American Century Investments       33



Under the Code, any distribution of a fund's net realized long-term capital
gains designated by the fund as a capital gain dividend is taxable to you as
long-term capital gains, regardless of the length of time shares are held. If a
capital gain dividend is paid with respect to any shares of a fund sold at a
loss after being held for six months or less, the loss will be treated as a
long-term capital loss to the extent of any distribution of long-term capital
gain.


Alternative Minimum Tax


While the interest on bonds issued to finance essential state and local
government operations is generally exempt from regular federal income tax,
interest on certain private activity bonds issued after August 7, 1986, while
exempt from regular federal income tax, constitutes a tax-preference item for
taxpayers in determining alternative minimum tax liability under the Code and
income tax provisions of several states.


The funds may each invest in private activity bonds. The interest on private
activity bonds could subject a shareholder to, or increase liability under, the
federal alternative minimum tax, depending on the shareholder's tax situation.


All distributions derived from interest exempt from regular federal income tax
may subject corporate shareholders to, or increase their liability under, the
alternative minimum tax because these distributions are included in the
corporation's adjusted current earnings.


The Trust will inform fund shareholders annually of the amount of distributions
derived from interest payments on private activity bonds.

HOW FUND PERFORMANCE INFORMATION  IS CALCULATED

The funds may quote performance in various ways. Historical performance
information will be used in advertising and sales literature.

For the money market funds, seven-day current yield quotations are based on the
change in the value of a hypothetical investment (excluding realized gains and
losses from the sale of securities and unrealized appreciation and depreciation
of securities) over a seven-day period (base period) and stated as a percentage
of the investment at the start of the base period (base-period return). The
base-period return is then annualized by multiplying by 365/7 with the resulting
yield figure carried to at least the nearest hundredth of one percent.

Calculations of seven-day effective yield begin with the same base-period return
used to calculate yield, but the return is then annualized to reflect weekly
compounding according to the following formula:


            Effective Yield = [(Base-Period Return + 1)(365/7)] - 1

The SEC 30-day yield calculation for non-money market funds is as follows:

                        Yield = (2 [(a - b + 1)(6) - 1])
                                     -----
                                       cd


where a = dividends and interest earned during the period, b = expenses accrued
for the period (net of reimbursements), c = the average daily number of shares
outstanding during the period that were entitled to receive dividends, and d =
the maximum offering price per share on the last day of the period.


The funds also may quote tax-equivalent yields. Tax-equivalent yields for
Tax-Free Money Market, Limited-Term Tax-Free, Intermediate-Term Tax-Free,
Long-Term Tax-Free and High-Yield Municipal are calculated using the following
equation:



34        American Century Investments                            1-800-345-2021


                                  Fund's Tax-Free Yield    =  Your Tax-Equivalent Yield
                               ---------------------------
                                  100% - Federal Tax Rate

Arizona Intermediate-Term Municipal's tax-equivalent yield is based on the
current double tax-exempt yield and your combined federal and state marginal tax
rate. Assuming all the funds' dividends are tax-exempt in Arizona (which may not
always be the case) and that your Arizona taxes are fully deductible for federal
income tax purposes, you can calculate your tax equivalent yield for the fund
using the equation below.

                          Fund's Double Tax-Free Yield
                  -------------------------------------------
             (100% - Federal Tax Rate)    (100% - Arizona Tax Rate)
                          = Your Tax-Equivalent Yield

Florida Municipal Money Market and Florida Intermediate-Term Municipal's
tax-equivalent yield is based on each fund's tax-free yield, your federal income
tax bracket, and the Florida Intangibles Tax applicable to a taxable investment.
The formula is:

                   Fund's Tax-Free Yield    + Florida Intangibles Tax Rate
              -----------------------------
                   100% - Federal Tax Rate
                          = Your Tax-Equivalent Yield


Total returns quoted in advertising and sales literature reflect all aspects of
a fund's return, including the effect of reinvesting dividends and capital gains
distributions (if any), and any change in the fund's NAV during the period.

Average annual total returns are calculated by determining the growth or decline
in value of a hypothetical historical investment in a fund during a stated
period and then calculating the annually compounded percentage rate that would
have produced the same result if the rate of growth or decline in value had been
constant throughout the period. For example, a cumulative total return of 100%
over 10 years would produce an average annual return of 7.18%, which is the
steady annual rate that would equal 100% growth on a compounded basis in 10
years. While average annual total returns are a convenient means of comparing
investment alternatives, investors should realize that the funds' performance is
not constant over time, but changes from year to year, and that average annual
total returns represent averaged figures as opposed to actual year-to-year
performance.


In addition to average annual total returns, each fund may quote unaveraged or
cumulative total returns reflecting the simple change in value of an investment
over a stated period, including periods other than one, five and 10 years.
Average annual and cumulative total returns may be quoted as percentages or as
dollar amounts and may be calculated for a single investment, a series of
investments, or a series of redemptions over any time period. Total returns may
be broken down into their components of income and capital (including capital
gains and changes in share price) to illustrate the relationship of these
factors and their contributions to total return.

EXPLANATION OF FIXED-INCOME SECURITIES RATINGS

As described in the Prospectus, the funds may invest in fixed-income securities.
Those investments, however, are subject to certain credit quality restrictions,
as noted in the Prospectus. The following is a summary of the rating categories
referenced in the prospectus disclosure.

BOND RATINGS
--------------------------------------------------------------------------------
S&P      Moody's    Description
--------------------------------------------------------------------------------
AAA      Aaa        These are the highest ratings assigned by S&P and Moody's to
                    a debt obligation. They indicate an extremely strong capacity
                    to  pay interest and  repay principal.
--------------------------------------------------------------------------------
AA       Aa         Debt rated in this category is considered to have a very
                    strong capacity to pay interest and repay principal and
                    differs from AAA/Aaa issues only in a  small degree.
--------------------------------------------------------------------------------
A        A          Debt rated A has a strong capacity to pay interest and repay
                    principal, although it is somewhat more susceptible to the
                    adverse effects of changes in circumstances and economic
                    conditions than debt in higher-rated categories.
--------------------------------------------------------------------------------
BBB      Baa        Debt rated BBB/Baa is regarded as having an adequate
                    capacity to pay interest and repay principal. Whereas it
                    normally exhibits adequate protection parameters, adverse
                    economic conditions or changing circumstances are more
                    likely to lead to a weakened capacity to pay interest and
                    repay principal for debt in this category than in
                    higher-rated categories.
--------------------------------------------------------------------------------
BB       Ba         Debt rated BB/Ba has less near-term vulnerability to default
                    than other speculative issues. However, it faces major
                    ongoing uncertainties or exposure to adverse business,
                    financial or economic conditions that could lead to
                    inadequate capacity to meet timely interest and principal
                    payments. The BB/Ba rating  category also is used for debt
                    subordinated to senior debt that is assigned an actual or
                    implied BBB-rating.
--------------------------------------------------------------------------------
B        B          Debt rated B has a greater vulnerability to default but
                    currently has the capacity to meet interest payments and
                    principal repayments. Adverse business, financial or
                    economic conditions will likely impair capacity or
                    willingness to pay interest and repay principal. The B
                    rating category is also used for debt subordinated to senior
                    debt that is assigned an actual or implied BB/Ba or BB-/Ba3
                    rating.
--------------------------------------------------------------------------------
CCC      Caa        Debt rated CCC/Caa has a currently identifiable
                    vulnerability to default and is dependent upon favorable
                    business, financial and economic conditions to meet timely
                    payment of interest and repayment of principal. In the event
                    of adverse business, financial or economic conditions, it is
                    not likely to have the capacity  to pay interest and repay
                    principal. The CCC/Caa rating category is also used for debt
                    subordinated to senior debt that is assigned an actual or
                    implied B or B-/B3 rating.
--------------------------------------------------------------------------------
CC       Ca         The rating CC/Ca typically is applied to debt subordinated
                    to senior debt that is assigned an actual or implied CCC/Caa
                    rating.
--------------------------------------------------------------------------------
C        C          The rating C typically is applied to debt subordinated to
                    senior debt, which is assigned an actual or implied
                    CCC-/Caa3 debt rating. The C rating may be used to cover a
                    situation where a bankruptcy petition has been filed, but
                    debt service payments are continued.
--------------------------------------------------------------------------------
CI       --         The rating CI is reserved for income bonds on which no
                    interest is being paid.
--------------------------------------------------------------------------------
D        D          Debt rated D is in payment default. The D rating category is
                    used when interest payments or principal payments are not
                    made on the date due even if the applicable grace period has
                    not expired, unless S&P believes that such payments will be
                    made during such grace period. The D rating also will be
                    used upon the filing of a bankruptcy petition if debt
                    service payments are jeopardized.
--------------------------------------------------------------------------------

To provide more detailed indications of credit quality, the Standard & Poor's
ratings from AA to CCC may be modified by the addition of a plus or minus sign
to show relative standing within these major rating categories. Similarly,
Moody's adds numerical modifiers (1,2,3) to designate relative standing within
its major bond rating categories. Fitch Investors Service, Inc. also rates bonds
and uses a ratings system that is substantially similar to that used by Standard
& Poor's.

COMMERCIAL PAPER RATINGS
--------------------------------------------------------------------------------
S&P       Moody's         Description
--------------------------------------------------------------------------------
A-1       Prime-1 (P-1)   This indicates that the degree of safety regarding
                          timely payment is strong. Standard & Poor's rates
                          those issues determined to possess extremely strong
                          safety characteristics as A-1+.
--------------------------------------------------------------------------------
A-2       Prime-2 (P-2)   Capacity for timely payment on commercial paper is
                          satisfactory, but the relative degree of safety is not
                          as high as for issues designated  A-1. Earnings trends
                          and coverage ratios, while sound, will be more subject
                          to variation. Capitalization characteristics, while
                          stillappropriated, may be more affected by external
                          conditions. Ample alternate liquidity  is maintained.
--------------------------------------------------------------------------------
A-3       Prime-3 (P-3)   Satisfactory capacity for timely repayment. Issues
                          that carry this rating are somewhat more vulnerable to
                          the adverse changes in circumstances than obligations
                          carrying the higher designations.
--------------------------------------------------------------------------------

NOTE RATINGS
--------------------------------------------------------------------------------
S&P       Moody's         Description
--------------------------------------------------------------------------------
SP-1      MIG-1; VMIG-1   Notes are of the highest quality enjoying strong
                          protection from
                          established cash flows of funds for their servicing or
                          from established and broad-based access to the market
                          for refinancing, or both.
--------------------------------------------------------------------------------
SP-2      MIG-2; VMIG-2   Notes are of high quality with margins of protection
                          ample, although not so large as in the preceding
                          group.
--------------------------------------------------------------------------------
SP-3      MIG-3; VMIG-3   Notes are of favorable quality with all security
                          elements accounted for, but lacking the undeniable
                          strength of the preceding grades. Market access for
                          refinancing, in particular, is likely to be less well
                          established.
--------------------------------------------------------------------------------
SP-4      MIG-4; VMIG-4   Notes are of adequate quality, carrying specific risk
                          but having protection and not distinctly or
                          predominantly speculative.
