AN OVERVIEW OF THE FUNDS


WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

These conservatively managed funds seek income that is exempt from federal and
California income tax. They also attempt to protect the value of your
investments.

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 California municipalities. 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 of the funds' investment strategies and risks begins
on page 9.

As with all funds, your shares may be worth more or less at any given time than
the price you paid for them. If you sell your shares when the value is less than
the price you paid, you will lose money.

[left margin]

DEBT SECURITIES include fixed-income investments such as notes, bonds,
commercial paper and debentures. Very short-term debt securities (those with
maturities shorter than one year) are called money market instruments.

WHO MAY WANT TO INVEST IN THE FUNDS?

The funds may be a good investment if you are
*  a California resident or taxpayer
*  seeking current tax-free income
*  comfortable with risk based on California'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

[left margin]

[graphic of pointing index 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 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

CALIFORNIA TAX-FREE MONEY MARKET FUND
CALIFORNIA MUNICIPAL MONEY MARKET FUND

WHAT ARE THE FUNDS' INVESTMENT OBJECTIVES?

These money market funds seek safety of principal and high current income that
is exempt from federal and California income taxes. This is a fundamental policy
and cannot be changed without shareholder approval.

HOW DO THE FUNDS PURSUE THEIR INVESTMENT OBJECTIVES?

The fund managers buy HIGH-QUALITY, very short-term debt securities with
interest payments exempt from federal and California income taxes. Cities,
counties and other municipalities in California usually issue these securities
for public projects, such as schools and roads.

California Municipal Money Market also buys high-quality, very short-term debt
securities whose payments are exempt from federal and California income taxes,
but that are not necessarily exempt from the federal alternative minimum tax.
Cities, counties and other municipalities in California usually issue these
securities (called private activity bonds) to fund for-profit private projects,
such as athletic stadiums, airports and apartment buildings.

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 ARE THE DIFFERENCES BETWEEN THE FUNDS?

*  California Tax-Free Money Market's income is exempt from all federal income
   tax.

*  California Municipal Money Market's income is exempt from regular federal
   income tax, but is not necessarily exempt from the federal alternative
   minimum tax.

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 these funds will likely be lower than funds that
invest in longer-term or lower-quality securities.

Because the funds invest primarily in California municipal securities, they will
be sensitive to events that affect California's economy. They may be riskier
than funds that invest in a larger universe of securities.

[left margin]

[graphic of pointing index finger]
Income from California Municipal Money Market 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 funds' advisor also can analyze an unrated security to
determine if its credit quality is high enough for investment. The details of
the funds' credit quality standards are described in the Statement of Additional
Information.

CALIFORNIA LIMITED-TERM TAX-FREE FUND
CALIFORNIA INTERMEDIATE-TERM TAX-FREE FUND
CALIFORNIA 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 and California income taxes.

HOW DO THE FUNDS PURSUE THEIR INVESTMENT OBJECTIVES?

The fund managers buy QUALITY DEBT SECURITIES with interest payments exempt from
federal and California income taxes. 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 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.

The funds also may use futures contracts and options as part of their investment
strategies.

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. To the extent 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 ARE THE DIFFERENCES BETWEEN THE FUNDS?


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

                                       Typical Maturity    Weighted

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

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.

Because the funds invest primarily in California municipal securities, they will
be sensitive to events that affect California's economy. They may be riskier
than funds that invest in a larger universe of securities.

The funds' share values will fluctuate. In general, funds that have higher
potential income have a higher potential loss. If you sell your shares when
their value is less than the price you paid, you will lose money.

                                        Potential Loss    Potential Income

CALIFORNIA INSURED TAX-FREE FUND


WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks safety of principal and high current income that is exempt from
federal and California income taxes.


HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund managers invest in long-term INSURED DEBT SECURITIES.

*  These debt securities feature interest payments exempt from federal and
   California income taxes. Cities, counties and other municipalities in
   California usually issue these securities for public projects.

*  A debt security's insurance cannot be cancelled and guarantees interest and
   other payments will be made as scheduled.


The weighted average maturity of the fund is expected to be 10 years or longer.

The fund also may use futures contracts and options as part of its investment
strategy.

During unusual market conditions, the fund is permitted to keep a significant
amount of its assets in cash or cash equivalents. If it does, it may not achieve
its investment objective and may generate taxable income.


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?


The fund invests in long-term insured debt securities. Generally, funds with
longer weighted average maturities are more sensitive to interest rate changes.
When interest rates rise, the values of bond funds usually fall, but the values
of funds with longer weighted average maturities generally will fall farther.

Because the fund invests primarily in California tax-free securities, it will be
sensitive to events that affect California's economy. It may be riskier than
funds that invest in a larger universe of securities.

The fund's investments are insured. This is significant because


*  the credit risk is less than that of funds investing in long-term debt
   securities without insurance, and


*  potential income is lower than that of funds investing in long-term debt
   securities without insurance

The fund's share value will fluctuate. In general, funds that have higher
potential income have a higher potential loss. If you sell your shares when
their value is less than the price you paid, you will lose money.

[left margin]

An INSURED DEBT SECURITY is a debt security that


*  is rated in the highest category by an independent rating agency, or

*  comes with insurance that guarantees interest and other payments will be
   made, or


*  has interest and principal payments secured by a special account holding U.S.
   government securities

The fund's primary focus on insurance features is essentially a way to pursue
very high credit-quality standards.

[graphic of pointing index finger]
The insurance feature of the fund's investments is not a guarantee; the fund
can still lose money.

CALIFORNIA HIGH-YIELD MUNICIPAL FUND

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The fund seeks safety of principal and high current income that is exempt from
federal and California income taxes.

HOW DOES THE FUND PURSUE ITS INVESTMENT OBJECTIVE?

The fund managers buy long- and intermediate-term debt securities with interest
payments exempt from federal and California income taxes. 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 athletic stadiums, airports and apartment
buildings.

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

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. To the extent a fund assumes a defensive
position, it will not be pursuing its investment objectives and may generate
taxable income.

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?

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 the interest and principal
due under its securities.

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.

Because the fund typically invests in intermediate-term and long-term bonds, the
fund's interest rate risk is higher than for funds with shorter weighted average
maturities, such as money market and short-term bond funds. See the discussion
on page 14 for more information about the effects of changing interest rates on
the fund's portfolio.

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 California's economy. California High-Yield Municipal may
have a higher level of risk than funds that invest in a larger universe of
securities.

As with all funds, your shares may be worth more or less at any given time than
the price you paid for them. If you sell your shares when the value is less than
the price you paid, you will lose money.

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 Treasury bills 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 it 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%           1,000 days     250 days
Debt Security B   300,000          75%          10,000 days   7,500 days
Weighted Average
  Maturity                                                    7,750 days

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 a fund's 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.


[left margin]

[graphic of pointing index finger]
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.



14        American Century Investments                           1-800-345-2021



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 investors 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.

INVESTMENT GRADE=========================++++++++++NON-INVESTMENT GRADE+++++++++

Securities rated in one of the highest four categories by a nationally
recognized securities rating organization 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 and an explanation of
certain exceptions to the guidelines reflected in the chart, see 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.

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


[graphic of pointing index finger]
The Statement of Additional Information provides a detailed description of these
securities ratings.

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.


A COMPARISON OF BASIC RISK FACTORS

The following chart depicts the basic risks of investing in the funds. It is
designed to help you compare these funds with each other; it shouldn't be used
to compare these funds with other mutual funds.

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. American Century 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 the 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 a fund is determined on a class-by-class basis monthly 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 Most Recent Fiscal Year Ended August 31, 1999
--------------------------------------------------------------------------------
California Tax-Free Money Market         0.50%
California Municipal Money Market        0.50%

California High-Yield Municipal          0.54%



www.americancentury.com                   American Century Investments     17


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 on the investment teams are identified below:

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 index 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.

(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 selected from the fund's portfolio
by the fund managers instead of cash. 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 want 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 you want to
redeem and the date of the transaction. This minimizes the effect of the
redemption on the fund and its remaining shareholders.



www.americancentury.com                   American Century Investments     21



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 index finger]
Financial intermediaries include banks, broker-dealers, insurance companies and
investment advisors.



22      American Century Investments                             1-800-345-2021


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 not open
(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 non-money market funds are not
readily available, the advisor may determine their fair value in accordance with
procedures adopted by the funds' Board. 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 NAV 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 by a fund, as well as CAPITAL GAINS
realized on the sale of investment securities.


Money Market Funds

Each money market fund declares distributions from net income daily. These
distributions are paid on the last Friday of each month. Distributions are
reinvested automatically in additional shares unless you choose another option.

Except as described in the next paragraph, you will begin to participate in fund
distributions the day after your purchase is effective. If you redeem shares,
you will receive the distribution declared for the day you redeem.

If you redeem all shares, we will include the distribution with your redemption
proceeds. You will begin to participate in fund distributions on the day your
instructions to purchase are received if you

*  notify us of your purchase prior to 11 a.m. Central time AND

*  pay for your purchase by bank wire transfer prior to 3 p.m. Central time on
   the same day

Also, we will wire redemptions to you by the end of the business day if you
request your redemption before 11 a.m. Central time.


[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      23



Other Funds

Each fund pays distributions from net income monthly. Each fund generally pays
capital gain distributions, if any, once a year, usually in December. A fund may
make more frequent distributions, if necessary, to comply with Internal Revenue
Code provisions. Distributions are reinvested automatically in additional shares
unless you choose another option.

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 unless you elect to receive them in cash. Please consult
your services guide for further information regarding distributions and your
distribution options.



24      American Century Investments                             1-800-345-2021


TAXES


Tax-Exempt Income

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

Certain 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 California 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.


                           Tax Rate for           Tax Rate for
Type of Distribution       15% Bracket            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
the fund held the underlying security that was sold, not by how long you have
been invested in the fund or whether you reinvest your distributions in
additional shares or take them in cash. 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.

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 redemption 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 and 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 remit 31% of dividends, capital
gains distributions and redemptions to the IRS.


[left margin]


[graphic of pointing index 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.

THE FUNDS' HISTORY

American Century California Tax-Free and Municipal Funds is a registered
open-end management investment company that was organized as a Massachusetts
business trust on February 18, 1983. From then until January 1997, it was known
as Benham California Tax-Free and Municipal Funds. Throughout this Statement of
Additional Information we refer to American Century California Tax-Free and
Municipal Funds as the Trust.

Each fund is a separate series of the Trust and operates for many purposes as if
it were  an independent company. Each fund has its own 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 discussion contained in the
Prospectus.

Each fund is a diversified open-end investment company as defined in the
Investment Company Act of 1940 (the Investment Company Act), with the exception
of the California Municipal Money Market which is non-diversified. 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.
California Municipal Money Market also will seek to meet this test.

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.

Each fund intends to remain fully invested in municipal obligations. As a
fundamental policy, each fund will invest at least 80% of its net assets in
California municipal obligations. A municipal obligation is a "California"
municipal obligation if its income is exempt from California state income taxes.

The remaining 20% of net assets may be invested in (1) municipal obligations
issued in other states and (2) U.S. government obligations. For temporary
defensive purposes, each fund may invest more than 20% of its net assets in
these obligations. For liquidity purposes, each non-money market fund may invest
up to 5% of its total assets in shares of money market funds, including
California Municipal Money Market and California Tax-Free Money Market.


www.americancentury.com                   American Century Investments     3


Each fund will invest at least 80% of its net assets in obligations with
interest exempt from regular federal income tax. California Municipal Money
Market and California High-Yield Municipal, unlike the other funds, may invest
substantially all of their assets in securities that are subject to the
alternative minimum tax. See "Alternative Minimum Tax," page 32.

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 36.

CALIFORNIA TAX-FREE MONEY MARKET FUND
CALIFORNIA MUNICIPAL MONEY MARKET FUND

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 maturity of 90 days or less

*  restricts its investments to high-quality obligations determined by the
   advisor, pursuant to procedures 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 comparable short-term
   obligations) in one of the two highest rating categories for short-term
   obligations by at least two nationally recognized statistical rating agencies
   ("rating agencies") (or one if only one has rated the obligation), or

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

While it adheres to the same quality and maturity criteria as California
Tax-Free Money Market, California Municipal Money Market may purchase private
activity municipal securities. The interest from these securities is treated as
a tax-preference item in calculating federal alternative minimum tax (AMT)
liability. In the past, private activity securities have provided somewhat
higher yields than comparable municipal securities whose interest is not a
tax-preference item. Therefore, the fund is designed for investors who do not
expect to pay alternative minimum taxes. See "Taxes," page 31.


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


California Limited-Term Tax-Free, California Intermediate-Term Tax-Free and
California Long-Term Tax-Free 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


4     American Century Investments                             1-800-345-2021



*  municipal notes (including variable-rate demand obligations) and tax-exempt
   commercial paper that is 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


CALIFORNIA INSURED TAX-FREE FUND

California Insured Tax-Free invests primarily in long-term municipal obligations
covered by insurance that guarantees the timely payment of interest and
repayment of principal.


Under normal conditions, at least 65% of the fund's total assets are invested in
insured municipal obligations. Securities held by the fund may be (1) insured
under a new-issue insurance policy obtained by the issuer of the security, (2)
insured under a secondary market insurance policy purchased by the fund or a
previous bondholder, (3) secured by an escrow or trust account holding U.S.
government securities, or (4) rated AAA by a rating agency based upon the
issuer's credit quality.


California Insured Tax-Free also may invest in short-term securities carrying
one of the two highest ratings designated by a rating agency.

CALIFORNIA HIGH-YIELD MUNICIPAL FUND


Like California Long-Term Tax-Free, California High-Yield Municipal invests
primarily in long- and intermediate-term California municipal obligations.
Although California 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 California High-Yield Municipal's
portfolio may consist of obligations that, when acquired, were not rated. There
is no limit to the percentage of assets the fund may invest in unrated
securities. The fund may invest up to 10% of its total assets in securities that
are in technical or monetary default.


California 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.


California 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, the
advisor expects to invest between 10% and 30% of the fund's total assets 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 the 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 California Municipal Securities


As noted in the Prospectus, the funds are susceptible to political, economic and
regulatory events that affect issuers of California municipal obligations. These
include possible adverse effects of California 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 California municipal securities. This
information is based on recent official statements relating to securities
offerings of California issuers, although it does not constitute a complete
description of the risk 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.


ECONOMIC OVERVIEW


California's economy is the largest among the 50 states and one of the largest
in the world. The state's 1998 population of approximately 33.5 million,
representing approximately 12% of the U.S. population, has grown by 51% since
1980. Total personal income, an estimated $904 billion in 1998, accounted for
approximately 12.7% of personal income nationwide.

From 1990 through 1993, the state suffered a severe recession, the worst since
the 1930s, heavily influenced by large cutbacks in defense/aerospace industries
and military base closures and a major drop in real estate construction.
California's economy has been recovering and growing steadily since the
beginning of 1994, to the point where the state's economic growth is outpacing
the rest of the nation. The state added more than 400,000 non-farm jobs in 1998,
while personal income grew by more than $58.4 billion. The unemployment rate,
while still higher than the national average, fell to the low 5.9% range in
mid-1998, compared to over 10% at the worst of the recession.

California's economic expansion is being fueled by strong growth in
high-technology industries, including computer software, electronics
manufacturing and motion picture/television production. Growth is also strong in
business services, export trade and manufacturing, with even the aerospace
sector showing increasing employment. Non-residential and



6     American Century Investments                             1-800-345-2021



residential construction have been growing moderately since the depths of the
recession, but remain much lower (as measured by annual new unit permits) than
the late 1980s.


CONSTITUTIONAL LIMITATIONS ON TAXES


Many California issuers rely on ad valorem property taxes as a source of
revenue. The taxing powers of California local governments and districts are
limited by Article XIIIA of the California Constitution, enacted by voters in
1978 and commonly known as "Proposition 13." Article XIIIA limits to 1% of full
cash value the rate of ad valorem taxes on real property and restricts the
reassessment of property to 2% per year, except where new construction or
changes of ownership have occurred (subject to a number of exemptions). Taxing
entities may, however, raise ad valorem taxes above the 1% limit to pay debt
service on voter-approved bonded indebtedness. The U.S. Supreme Court has upheld
Proposition 13 against claims that it has unlawfully resulted in widely varying
tax liability on similarly situated properties.

Article XIIIA also requires voters of any governmental unit to give two-thirds
approval to levy any special tax. Subsequent court decisions, however, have
allowed non-voter approved general taxes so long as they are not dedicated to a
specific use. In response to these decisions, voters adopted an initiative in
1986 that imposed new limits on the ability of local government entities to
raise or levy general taxes without voter approval. Based upon a 1991
intermediate appellate court decision, it was believed that significant parts of
this initiative, known as Proposition 62, were unconstitutional. On September
28, 1995, the California Supreme Court rendered a decision in the case of Santa
Clara County Local Transportation Authority vs. Guardino that rejected the prior
decision and upheld Proposition 62, while striking down a 1/2-cent sales tax for
transportation purposes that was approved by a majority, but less than
two-thirds, vote. Proposition 62 does not apply to charter cities, but other
local governments may be constrained in raising any taxes without voter
approval.

On November 5, 1996, the voters of the state approved Proposition 218. This
proposition adds Articles XIIIC and XIIID to the state Constitution, which
affect the ability of local governments, including charter cities, to levy and
collect both existing and future taxes, assessments, fees and charges.
Proposition 218 became effective on November 6, 1996, although application of
some of its provisions was deferred until July 1, 1997. This proposition could
negatively impact a local government's ability to make its debt service
payments, and thus could result in lower credit ratings.


CONSTITUTIONAL LIMITATIONS ON APPROPRIATIONS


The state and its local governments are subject to an annual appropriations
limit imposed by Article XIIIB of the California Constitution. This article was
enacted by voters in 1979 and was significantly amended by Propositions 98 and
111 in 1988 and 1990, respectively. Article XIIIB prohibits the state and
subject local governments from spending "appropriations subject to limitation"
in excess of an appropriations limit. The appropriations limit is adjusted
annually to reflect population changes and changes in the cost of living as well
as transfers of responsibility between government units. "Appropriations subject
to limitation" are authorizations to spend "proceeds of taxes" consisting of tax
revenues and certain other charges and fees to the extent that such proceeds
exceed the cost of providing the product or service. However, proceeds of taxes
exclude most state subventions to local governments.

"Excess revenues" under Article XIIIB are measured over a two-year cycle. Local
governments must return any excess revenues to taxpayers through tax rate
reductions. The state must refund 50% of any excess and pay the other 50% to
schools and community colleges. With the application of more liberal annual
adjustment factors since 1988 and depressed revenues since 1990 due to the
recession, few governments are currently operating near their spending limits,
but this condition may change over time. Local governments may, by voter
approval, exceed their spending limits for a limited time.

Because of the complex nature of Articles XIIIA and XIIIB, the ambiguities and
possible inconsistencies in their terms and the impossibility of predicting
future appropriations, population changes, changes in the cost of living or the
probability of continuing legal challenges, it is difficult to measure the full
impact of these Articles on the California municipal market or on the ability of
California issuers to pay debt service on their obligations.


OBLIGATIONS OF THE STATE OF CALIFORNIA


As of August 1, 1999, the state had approximately $19.9 billion of general
obligation bonds outstanding, and approximately $12.7 billion remained
authorized but unissued. Of the state's outstanding general obligation debt, 18%
is presently self-liquidating (i.e., program revenues are expected to be
sufficient to reimburse the General Fund for debt service payments). In fiscal
year 1998-99, debt service on general obligation bonds and lease-purchase debt
was approximately 4.4% of general fund revenues, approximately the same as for
1997-98, down from 4.98% in fiscal year 1996-97.

The state's principal sources of General Fund revenues for fiscal year 1998-99
were the California personal income tax (52.7% of total revenues), the sales tax
(32.1%), bank and corporations taxes (9.3%) and the gross premium tax on
insurance (2.2%). Historically, the state has paid the principal of and interest
on its general obligation bonds, lease-purchase debt and short-term obligations
when due.

General. Pressures on the state's budget in the late 1980s and early 1990s were
caused by a combination of external economic conditions and growth of the
largest General Fund expenditure programs--K-12 education, health, welfare and
corrections--at rates faster than the revenue base. The largest state
expenditure program is assistance to local public school districts. In 1988,
Proposition 98 was enacted; it essentially guarantees local school districts and
community college districts a minimum share of the state's General Fund revenues
(currently 35%).

Expenditures pressures could continue as the state's overall population and
school age population continue to grow, and as the state's corrections program
responds to a "Three Strikes" law enacted in 1994 (which requires mandatory life
prison terms for certain third-time felony offenders). In addition, the
long-term impact of federal welfare reform on the state's budget is uncertain.

Recent Budgets. State finances have improved over the past four fiscal years,
due primarily to stronger than anticipated revenue and lower than anticipated
social spending. The state finished fiscal year 1998-99 with an estimated $2.4
billion fund balance. The fiscal 1999 budget contained the following features:

*  Funding for higher education was increased substantially as funding for the
   University of California and the California State University System is
   budgeted to increase 15.6% and 14.1%, respectively.

*  The budget includes increased funding for health, welfare and social services
   programs based primarily on a 4.9% grant increase, the first such increase in
   nine years.


*  Funding for judiciary and criminal justice programs increased about 11%
   reflecting increased state support for local trial courts and rising prison
   population.


*  The budget also includes a dedication of $376 million of General Fund moneys
   for capital outlay projects, funding of a 3% State employee salary increase,
   funding of 2,000 new Department of Transportation positions to accelerate
   transportation construction projects, and funding of the Infrastructure and
   Economic Development Bank ($50 million).

*  The budget contains a tax reduction of $1.4 billion, primarily reflected in
   the phased-in reduction of the Vehicle License Fee (VLF). Other tax
   reductions include both a temporary and permanent increase in the personal
   income tax dependent credit, a nonrefundable renters' tax credit, and various
   targeted business tax credits.



8     American Century Investments                             1-800-345-2021



Current Budget. The Budget Act anticipates General Fund revenues and transfers
of  $63.0 billion (8.7% increase from the prior fiscal year) and expenditures of
$63.7 billion (an 8.8% increase). On a budgetary basis, the General Fund balance
is projected to decrease from $2.4 billion as of June 30, 1999, to $1.7 billion
as of June 30, 2000. The following are major features of the 1999-00 Budget Act:

*  Proposition 98 Funding for K-12 schools was increased by $1.6 billion over
   revised fiscal year levels and $108.6 million higher than the minimum
   Proposition 98 guarantee.

*  Funding for higher education increased by $184 million (7.3%) for the
   University of California, $126.0 million (5.9%) for the California State
   University System and $324.3 million (6.6%) for community colleges.

*  Funding for health and human services increased nearly $600 million.

*  $800 million from the General Fund will be directed toward infrastructure,
   including $425 million in additional funding for the Infrastructure Bank.

*  The Legislature enacted a one-year reduction of 10% in the Vehicle License
   Fee (VLF) for calendar year 2000, at a cost of about $250 million in fiscal
   year 2000 and 2001. In addition, several targeted tax cuts, primarily for
   business, also were approved at a cost of $54 million in fiscal year 2000.

*  A one-time appropriation of $150 million, to be split between cities and
   counties, was made to offset property tax shifts during the early 1990s.

Due to the improvement in the state's economy and financial condition, the State
of California was upgraded by Moody's Investors Service in October 1998 from A1
to Aa3; by Standard and Poor's in August 1999 from A+ to AA-; and by Fitch
Investors Service in September 1997 from A+ to AA-.


OBLIGATIONS OF OTHER ISSUERS IN CALIFORNIA


Property tax revenues received by local governments declined more than 50%
following the passage of Proposition 13 in 1978. Subsequently, the California
legislature enacted measures to provide for the redistribution of the state's
General Fund surplus to local agencies, the reallocation of certain state
revenues to local agencies, and the assumption of certain government functions
by the state to assist the state's municipalities. However, in response to the
fiscal crisis at the state level, the Legislature in 1992-93 and 1993-94
effectively reversed the post-Proposition 13 bailout aid and directed over $3
billion of city, county and special district property taxes to school districts,
which enabled the state to reduce its aid to schools by the same amount. Part of
this shortfall is to be covered by a 0.5% sales tax allocated to local
government public safety purposes. The 0.5% sales tax increase was imposed by
Proposition 172, which was approved by a majority of voters at the statewide
election on November 2, 1993.

Even with these cuts and property tax shifts, more than 70% of the state's
General Fund expenditures are for local government assistance. To the extent
that the state is constrained by its Article XIIIB appropriations limit, its
obligation to conform to Proposition 98 or other fiscal considerations, the
absolute level or rate of growth of state assistance to local governments may be
reduced. Any such reductions in state aid could compound the serious fiscal
constraints already experienced by many local governments, particularly
counties.


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



www.americancentury.com                   American Century Investments     9


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 the State of California 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. General
obligation 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

The funds may buy variable- and floating-rate demand obligations (VRDOs and
FRDOs). These obligations 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


10     American Century Investments 1-800-345-2021


the interest rate. 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

Each fund may invest in fixed-rate bonds subject to third-party puts and in
participation interests in such bonds held by a bank in trust or otherwise.
These bonds and participation interests 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 a remarketing agent will renege on a tender option
agreement 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 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 they 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, a fund 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 forth
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.


California and its municipalities are the largest issuers of municipal lease
obligations in the United States.

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 by (1) 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 California 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.


www.americancentury.com                   American Century Investments     13



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.


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:

*  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

In addition, each fund may invest part of its assets in other investment
companies, including money market funds. Under the Investment Company Act, a
fund's investment in such securities, subject to certain exceptions, 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.

If a fund invests in U.S. government securities, a portion of dividends paid to
shareholders will be taxable at the federal level, and may be taxable at the
state level, as ordinary income. However, the advisor intends to minimize such
investments and, when suitable short-term municipal securities are unavailable,
may allow the funds to hold cash to avoid generating taxable dividends.

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 indices such as the Bond
Buyer Municipal Bond Index that are consistent with the funds' investment
objectives. The funds 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



www.americancentury.com                     American Century Investments     15



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.

Municipal Bond Insurers

Securities held by California Insured Tax-Free may be (a) insured under a
new-issue insurance policy obtained by the issuer of the security or (b) insured
under a secondary market insurance policy purchased by the fund or a previous
bond holder. The following paragraphs provide some background on the bond
insurance organizations most frequently relied upon for municipal bond insurance
in the United States.

AMBAC Indemnity Corporation (AMBAC Indemnity) is a Wisconsin-domiciled stock
insurance corporation. AMBAC Indemnity is a wholly owned subsidiary of AMBAC
Inc.,  a publicly held company. Moody's Investors Service, Inc. (Moody's) and
Standard & Poor's Corporation (S&P) have rated AMBAC Indemnity's claims-paying
ability Aaa and AAA, respectively.

Financial Guaranty Insurance Company (FGIC) is a wholly owned subsidiary of FGIC
Corporation, a Delaware corporation. FGIC's claims-paying ability was rated
Aaa/AAA/AAA by Moody's, S&P and Fitch, respectively.

Municipal Bond Investors Assurance (MBIA) Corporation is a monoline insurance
company organized as a New York corporation. All bond issues insured by MBIA are
rated "Aaa" by Moody's and all short-term loans insured by MBIA are rated
"MIG-1." All bond issues insured by MBIA are rated "AAA" by S&P.

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 following restrictions apply at the time transactions are entered
into. 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.

For purposes of the funds' investment restrictions, the party identified as the
"issuer" of a municipal security depends on the form and conditions of the
security. When the assets and revenues of a political subdivision are separate
from those of the government that created the subdivision and the security is
backed only by the assets and revenues of the


www.americancentury.com                    American Century Investments     17


subdivision, the subdivision is deemed the sole issuer. Similarly, in the case
of an Industrial Development Bond, if the bond were backed only by the assets
and revenues of a non-governmental user, the non-governmental user would be
deemed the sole issuer. If, in either case, the creating government or some
other entity were to guarantee the security, the guarantee would be considered a
separate security and treated as an issue of the guaranteeing entity.

FUNDAMENTAL INVESTMENT POLICIES

The funds are subject to the following restrictions that are fundamental and 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.

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 its
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.

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 33 1/3% of the fund's total assets
                      (including the amount borrowed) less liabilities (other
                      than borrowings).

Lending               A fund may not lend any security or make any other loan
                      if, as a result, more than 33 1/3% 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 a fund from
                      investing 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.


18     American Century Investments                             1-800-345-2021


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.

Nonfundamental Investment Policies

In addition, the funds are subject to the following additional 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
                      at any time during which outstanding borrowings exceed 5%
                      of the total assets of the fund.

Futures and options   The money market funds may not purchase or sell futures
[Money market funds   contracts or call options. This limitation does not apply
 only]                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 repurchase agreements not entitling the holder
                      to payment of principal and interest within seven days and
                      in securities that are 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.


www.americancentury.com                   American Century Investments     19


The funds' portfolio turnover rates (except those of the money market funds) are
listed in the Financial Highlights table in the Prospectus. 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; the 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 and co-administrator, Funds Distributor, Inc. (FDI); or other funds
advised by the advisor. Each trustee listed below serves as a trustee or
director of seven registered investment companies in the American Century family
of funds, which also are advised by the advisor.

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 activities of the Trust's
            Albert A. Eisenstat  independent auditor. The committee receives reports from the
            Jeanne D. Wohlers    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 and recommends
            Myron S. Scholes     individuals for nomination as trustees. The names of potential
            Albert A. Eisenstat  trustee candidates are drawn from a number of sources, including
            Ronald J. Gilson     recommendations from members of the Board, management and
            Isaac Stein          shareholders. This committee also reviews and makes
            Jeanne D. Wohlers    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 investment activities
            Ronald J. Gilson     and strategies used to manage fund assets. The committee regularly
            Isaac Stein          receives reports from portfolio managers, credit analysts and other
                                 investment personnel concerning the funds' investments.

Quality     Isaac Stein          The Quality of Service Committee reviews the level and quality of
of Service  William M. Lyons     transfer agent and administrative services provided to the funds and
            Ronald J. Gilson     their shareholders. It receives and reviews reports comparing those
            Myron S. Scholes     services to those of fund competitors 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 California Tax-Free and Municipal Funds.
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.

Jeanne D. Wohlers       79,750                1,765

(1) Includes compensation paid to the trustees during the fiscal year ended
    August 31, 1999, and also includes amounts deferred at the election of the
    trustees under the American Century Mutual Funds Deferred Compensation Plan
    for Non-Interested Directors and Trustees. The total amount of deferred
    compensation included in the preceding table is as follows: Mr. Eisenstat,
    $1,245; Mr. Gilson, $2,111; Mr. Scholes, $739; and Mr. Scott, $1,054.

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

The funds have adopted the American Century Deferred Compensation Plan for
Non-Interested Directors and Trustees. 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. 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 August 31, 1999.

THE FUNDS' PRINCIPAL SHAREHOLDERS

As of December 3, 1999, the following companies were the record owners of more
than 5% of a fund's outstanding shares:

Fund                                 Shareholder and Percentage of Shares Outstanding
-------------------------------------------------------------------------------------
California Tax-Free Money Market     Morgan Guaranty Trust of NY   22.2%
                                     Newark, DE

California Municipal Money Market    Morgan Guaranty Trust of NY   13.2%
                                     Newark, DE

California Limited-Term Tax-Free     Bank of America NA            13.4%
                                     Dallas, TX

California High-Yield Municipal      Morgan Guaranty Trust of NY    7.5%
                                     Newark, DE

The funds are unaware of any other shareholders, beneficial or of record, who
own more than 5% of a fund's outstanding shares. As of December 3, 1999, the
officers and trustees of the funds, as a group, own less than 1% of any 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 and ACSC 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.

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 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 provides 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 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 incurred by each fund for the fiscal periods ended
August 31, 1999, 1998 and 1997, are indicated in the following table. Fee

DISTRIBUTOR

The funds' shares are distributed by FDI, a registered broker-dealer. The
distributor is a wholly owned, indirect subsidiary of Boston Institutional
Group, Inc. The distributor's principal business address is 60 State Street,
Suite 1300, Boston, Massachusetts 02109.

The distributor is the principal underwriter of the funds' shares. The
distributor makes a continuous, best-efforts underwriting of the funds' shares.
This means that the distributor has 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 serves
as custodian of the assets of the funds. The custodians take no part in
determining the investment policies of the funds or in 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 funds generally purchase and sell 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 of securities from underwriters 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
August 31, 1997, 1998, and 1999, 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' Prospectus and in Your Guide to American Century Services. The Prospectus
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), usually at 4 p.m.
Eastern time each day the Exchange is open for business. 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


www.americancentury.com                      American Century Investments     29


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, the Board 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 directors
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 they were realized by the
funds.

Certain 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 a
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.

As of August 31, 1999, the funds on the table below had the following capital
loss carryovers. When a fund has a capital loss carryover, it does not make
capital gains distributions until the loss has been offset or expired.

Fund                                    Capital Loss Carryover
-------------------------------------------------------------------------------
California Tax-Free Money Market        $274,509 (expiring in 2004 through 2007
California Municipal Money Market       $159,057 (expiring in 2003 through 2006
California Limited-Term Tax-Free        $445,336 (expiring in 2004)

Interest on certain types of industrial development bonds (small issues and
obligations issued to finance certain exempt facilities that may be leased to or
used by persons other than the issuer) is not exempt from federal income tax
when received by "substantial users" or persons related to substantial users as
defined in the Code. The term "substantial user" includes any "non-exempt
person" who regularly uses in trade or business part of a facility financed from
the proceeds of industrial development bonds. The funds may invest periodically
in industrial development bonds and, therefore, may not be appropriate
investments for entities that are substantial users of facilities financed by
industrial development bonds or "related persons" of substantial users.
Generally, an individual will


www.americancentury.com                   American Century Investments     31


not be a related person of a substantial user under the Code unless he or his
immediate family (spouse, brothers, sisters, ancestors and lineal descendants)
owns directly or indirectly in aggregate more than 50% in the equity value of
the substantial user.

Under the Code, any distribution of a fund's net realized long-term capital
gains that is designated by the fund as a capital gains dividend is taxable to
shareholders as long-term capital gains, regardless of the length of time shares
are held. If a capital gains 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 for tax purposes.

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.

California Municipal Money Market and California High-Yield Municipal 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. The interest on
California private activity securities is not subject to the California
alternative minimum tax when it is earned (either directly or through investment
in a mutual fund) by a California taxpayer. However, if either fund were to
invest in private activity securities of non-California issuers (due to a
limited supply of appropriate California municipal obligations, for example),
the interest on those securities would be included in California alternative
minimum taxable income.


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."


In addition, a deductible environmental tax of 0.12% is imposed on a
corporation's modified alternative minimum taxable income in excess of $2
million. The environmental tax will be imposed even if the corporation is not
required to pay an alternative minimum tax. To the extent that exempt-interest
dividends paid by a fund are included in alternative minimum taxable income,
corporate shareholders may be subject to the environmental tax.

The Trust will inform California Municipal Money Market and California
High-Yield Municipal fund shareholders annually of the amount of distributions
derived from interest payments on private activity bonds.

STATE AND LOCAL TAXES

California law concerning the payment of exempt-interest dividends is similar to
federal law. Assuming each fund qualifies to pay exempt-interest dividends under
federal and California law, and to the extent that dividends are derived from
interest on tax-exempt bonds of California state or local governments, such
dividends also will be exempt from California personal income tax. The Trust
will inform shareholders annually as to the amount of distributions from each
fund that constitutes exempt-interest dividends and dividends exempt from
California personal income tax. The funds' dividends are not exempt from
California state franchise or corporate income taxes.

The funds' dividends may not qualify for exemption under income or other tax
laws of state or local taxing authorities outside California. Shareholders
should consult their tax advisors or state or local tax authorities about the
status of distributions from the funds in this regard.


32     American Century Investments                             1-800-345-2021


The information above is only a summary of some of the tax considerations
affecting the funds and their shareholders. No attempt has been made to discuss
individual tax consequences. A prospective investor should consult with his or
her tax advisors or state or local tax authorities to determine whether the
funds are suitable investments.


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, 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 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

For the non-money market funds, yield quotations are based on the investment
income per share earned during a particular 30-day period, less expenses accrued
during the period (net investment income), and are computed by dividing the
fund's net investment income by its share price on the last day of the period
according to the following formula:
                                              6
                        YIELD = 2 [(a - b + 1)  - 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 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 California (which may not always be the case) and
that your California taxes are fully deductible for federal income tax purposes,
you can calculate your tax equivalent yield for the funds using the following
equation:

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

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


www.americancentury.com                     American Century Investments     33


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 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.


36     American Century Investments                             1-800-345-2021


S&P   Moody's   Description
--------------------------------------------------------------------------------
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   This indicates that the degree of safety regarding timely
      (P-1)     payment is strong. Standard & Poor's rates those issues
                determined to possess extremely strong safety characteristics as
                A-1+.

A-2   Prime-2   Capacity for timely payment on commercial paper is satisfactory,
      (P-2)     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   Satisfactory capacity for timely repayment. Issues that carry
      (P-3)     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;    Notes are of the highest quality enjoying strong protection from
      VMIG-1    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;    Notes are of high quality, with margins of protection ample,
      VMIG-2    although not so large as in the preceding group.

SP-3  MIG-3;    Notes are of favorable quality, with all security elements
      VMIG-3    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;    Notes are of adequate quality, carrying specific risk but having
      VMIG-4    protection and not distinctly or predominantly speculative.
