Y2K TESTING EFFORTS PAY
DIVIDENDS IN PREPAREDNESS
- --------------------------------------------------------------------------------

Y2K, short for the Year 2000, refers more specifically to the date change from
December 31, 1999 to January 1, 2000. This date change is significant for
computers because many were originally programmed to process dates with
two-character years--99 instead of 1999.

When the calendar rolls to 2000, this can create problems for computers
programmed this way because they will read the date as "00," and may interpret
it as 1900. Most companies have been working to reprogram their computer systems
with four-digit years. Reprogramming is very labor-intensive and requires
testing to ensure that there are no errors and that all lines of  code were
successfully changed.

Recognizing the possible impact of the Y2K issue, our senior-level Steering
Committee,  programmers, business partners and Y2K team have been working
diligently to make  January 1, 2000 a non-event for American Century investors.

Currently, our systems have been modified, tested and returned to production,
and we have tested our systems with our vendors and business partners.

In March and April of this year, we participated in the Security Industry
Association's (SIA) industry-wide test and successfully processed transactions
for dates up to and beyond 2000. American Century transactions with our partner
firms were processed free of Y2K bugs. We also participated in the Market Data
Test conducted by the SIA and Financial Information Forum in May. Again, the
computer scripts were executed successfully with no Y2K-related errors.

In addition, our Y2K team has developed contingency plans. These plans are
designed to  minimize the impact on our investors and help us maintain
operations in the event of any  Y2K-related incidents. We have conducted
practice drills of contingency scenarios and will continue to refine our plans
during the rest of 1999 to respond quickly and effectively so that the date
change is as seamless as possible for investors. We expect the Year 2000 to be
business as usual at American Century.

     Strong economic growth, increasing inflation anxiety, and rising interest
rates set the tone for the U.S. bond market in 1999. These factors helped
determine the performance of American Century's California municipal funds for
the fiscal year ended August 31, 1999.

     Municipal bond funds enjoyed gains during the second half of 1998 when
interest rates fell and bond markets rallied. Those positive returns were
largely negated in 1999, however, as the recovery of overseas economies and
unabated U.S. growth reignited inflation fears and sent interest rates soaring.
While the Federal Reserve (the Fed--the U.S. central bank) saw fit to cut
short-term interest rates three times during the fall of 1998, the Fed raised
rates twice during the summer of 1999.

     Though market behavior and Fed interest rate policy swung from one extreme
to the other, one thing that remained remarkably consistent was the performance
of the American Century California municipal funds against their peers. All
seven of our California municipal money market and bond funds provided higher
tax-free yields and lower expenses than the average of their Lipper Inc. peer
groups. That's a hallmark of the American Century municipal investment approach.

     The strength of our municipal investment and credit research teams also
contributed to fund performance. The investment and credit teams, as well as
fund investors, have benefited from our commitment to build and maintain a
talented fund management group. American Century's entire investment management
team has doubled in size over the past three years.

     In addition to strengthening our portfolio and research staff, we've
recently made strategic investments in several other financial companies,
including Archipelago, Tradepoint Financial Networks, W.R. Hambrecht, and
WorldStreet Corporation. These investments demonstrate our active support of the
development and use of technologies that improve the efficiencies of capital
markets, lower trading costs, and ultimately offer better returns for
shareholders.

     One final note--in the spirit of our ongoing Year 2000 readiness
disclosures, we've provided a complete update on our preparations for Y2K on the
inside front cover of this report. We understand that our continued diligence in
this area is very important to you.

     As always, we appreciate your continued confidence in American Century.

Sincerely,

Report Highlights
- --------------------------------------------------------------------------------

CALIFORNIA TAX-FREE MONEY MARKET

*   California Tax-Free Money Market produced more state and federal tax-free
    income and had higher returns than the average California money market
    fund in the fiscal year ended August 31, 1999.

*   One reason the portfolio delivered such good relative performance is that
    it has lower-than-average management expenses. Other things being equal,
    lower expenses mean higher yields and returns for our shareholders.

*   We were also able to produce very competitive yields because we've developed
    excellent working relationships with those dealers that offer attractive
    rates on California money market securities.

*   The fund's yield increased significantly during the fiscal year. That's
    primarily because the Federal Reserve raised interest rates twice during
    the summer to try to cool the economy and head off inflation.

*   Though interest rates are higher overall, yields on California money market
    securities are below national levels. California's healthy economy has
    reduced state and local borrowing needs. That means less supply, while
    demand for state tax-free securities remains high.

*   We'd like to lock in higher rates by extending the fund's average maturity,
    but we'll likely wait until yields on California securities become more
    attractive relative to national levels.

CALIFORNIA MUNICIPAL MONEY MARKET

*   California Municipal Money Market provided shareholders more state and
    federal tax-free income than the average California money market fund. The
    fund's return ranked in  the top 15% of the Lipper group  (see page 10 for
    complete ranking information).

*   California Municipal Money Market's yield and return are higher than those
    of California Tax-Free Money Market because the municipal fund holds
    securities subject to the federal alternative minimum tax (AMT). AMT
    securities typically offer higher yields than non-AMT securities.
    California Municipal Money Market is most appropriate for investors who do
    not file under the AMT.

*   The key to the fund's solid relative performance is our below-average
    management fees. Other things being equal, lower expenses mean higher
    yields and returns for our shareholders.

*   Though the portfolio's yield increased during the year, interest rates on
    California money market securities lagged those on national money market
    instruments. California's healthy economy has reduced state and local
    borrowing needs at a time when demand for state tax-free securities is
    high.

*   Looking ahead, we'd like to lock in higher rates by extending the fund's
    average maturity, but we'll likely wait until yields on California
    securities become more attractive relative to national levels.

Money Market Funds--Frequently Asked Questions
- --------------------------------------------------------------------------------

CAN I MAKE DIRECT DEPOSITS INTO MY MONEY MARKET FUND ACCOUNT?

     Yes. You can arrange for direct deposit of your paycheck, Social Security
check, Treasury Direct interest payment, military allotment, or payments from
other government agencies. Give us a call, and we will send you the necessary
information to set it up.

WHAT IS THE HOLDING PERIOD ON NEW DEPOSITS INTO MY ACCOUNT?

     Generally, there is an eight-business-day holding period for deposited
funds (initial investments in a new account are held for 15 calendar days).
There is a one-business-day holding period for U.S. Treasury checks, money
orders, and travelers' checks.

IS THERE A LIMIT ON THE NUMBER OF  CHECKS I CAN WRITE ON MY MONEY  MARKET
ACCOUNT?

     No. You can write as many checks as you like at no charge, as long as each
check is for $100 or more.

IS THERE AN EASY WAY TO MOVE MONEY  FROM MY MONEY MARKET FUND INTO A  STOCK OR
BOND FUND?

     Yes. Moving money between funds is called an exchange, and there is no
limit on the number of exchanges you can make out of a money market fund
account. However, there is a limit of six exchanges per calendar year out of
stock and bond fund accounts.

     Exchanges can be made by:

*    visiting our Web site at
     www.americancentury.com*

*    using our Automated Information Line (1-800-345-8765)*

*    calling an Investor Relations Representative at 1-800-345-2021*

*    writing us a letter

HOW DO I DECIDE WHETHER A TAXABLE MONEY MARKET FUND OR A TAX-FREE MONEY MARKET
FUND IS RIGHT FOR ME?

     The most important factor to consider is your tax bracket. Tax-free money
market funds typically offer lower yields than taxable funds, but you pay no
federal income taxes on the income from a tax-free fund.

     If you are in one of the higher federal income tax brackets, taxes will eat
up a big part of your income from a taxable money market fund, so a tax-free
investment may be better for you. If you're in a lower tax bracket, then you can
usually earn more in a taxable fund even after taxes are deducted.

     We can help you figure it out. If you give us a call and tell us what tax
bracket you're in, we can tell you whether you're likely to earn more after-tax
income in a tax-free or a taxable money market fund.

IF YOU HAVE ANY QUESTIONS ABOUT OUR MONEY MARKET FUNDS, CALL US TOLL FREE AT
1-800-345-2021 OR E-MAIL US AT OUR WEB SITE, WWW.AMERICANCENTURY.COM.

*  Before an investor can make an exchange by calling an Investor Relations
   Representative, using our Automated Information Line, or visiting our Web
   site, the investor first must have provided us with written authorization
   to do so.

A FASTER AND EASIER WAY TO DEPOSIT MUTUAL FUND DISTRIBUTIONS

If you prefer to have your fund dividend or capital gains distributions sent to
you instead of reinvesting them, there are a couple of ways to get access to
this money faster than waiting for a check in the mail:

*  YOU CAN HAVE DISTRIBUTIONS DEPOSITED DIRECTLY INTO YOUR MONEY MARKET
   ACCOUNT. The money will be deposited the same day that the distributions
   are paid.

*  DISTRIBUTIONS CAN BE SENT ELECTRONICALLY TO YOUR BANK ACCOUNT. The money
   will be available in your bank account within three days.

Contact our Investor Relations Representatives to set up either of these
options.

California Tax-Free Money Market--Q&A
- --------------------------------------------------------------------------------
[photo of Todd Pardula]

     An interview with Todd Pardula, a portfolio manager on the California
Tax-Free Money Market fund investment team.

HOW DID CALIFORNIA TAX-FREE MONEY MARKET PERFORM DURING THE FISCAL YEAR ENDED
AUGUST 31, 1999?

     California Tax-Free Money Market produced a total return of 2.62%. That's
better than the average California tax-exempt money market fund, which returned
2.47% for the same period, according to Lipper Inc. California  Tax-Free Money
Market's return was good enough to rank in the top quarter of the Lipper group.
(See the previous page for additional fund performance comparisons.)

HOW DOES THE PORTFOLIO'S YIELD COMPARE?

     The fund continued to provide shareholders with more state and federal
tax-free income than the average California money fund. California Tax-Free
Money Market's 7-day effective yield on August 31, 1999, was 2.57%, while the
average yield of the 51 California tax-exempt money market funds tracked by
Lipper was 2.41%.

WHY DID CALIFORNIA TAX-FREE MONEY MARKET PRODUCE BETTER YIELDS AND RETURNS THAN
ITS LIPPER GROUP?

     The key to the portfolio's solid relative performance was our
lower-than-average management fee. Other things being equal, lower expenses mean
higher yields and returns for our shareholders.

     Another reason the fund performed well was our ability to buy securities at
attractive yields and prices. We're able to do that because we've developed
solid working relationships with securities dealers who offer very good rates on
California money market securities.

     We also made some good judgment calls about the market. For example, we
decided not to buy some notes issued in early June because of their low yields.
That turned out to be a good move because new issues came to market a few weeks
later offering yields 25 basis points higher. (A basis point equals 0.01%, so 25
basis points equal 0.25%.)

CALIFORNIA TAX-FREE MONEY MARKET'S YIELD INCREASED, PARTICULARLY IN THE PAST SIX
MONTHS. WHY?

     Money market yields are higher primarily because the Federal Reserve raised
interest rates twice in the last six months to try to cool the economy and head
off potential inflation. In addition, the market expects at least one more rate
hike.

     But it's worth noting that yields on California money market securities are
low relative to national levels. That's because demand for California securities
is high, while supply is lower than in years past because California's strong
economy has reduced security issuance.

WHAT IS YOUR OUTLOOK FOR THE FUND?

     We'd like to extend the average maturity slightly by adding some
higher-yielding one-year securities. However, we'll likely hold off on extending
the maturity until the difference in yield between California and national notes
returns to more normal levels.

California Municipal Money Market--Q&A
- --------------------------------------------------------------------------------

     An interview with Todd Pardula (pictured on page 5), a portfolio manager on
the California Municipal Money Market fund investment team.

HOW DID CALIFORNIA MUNICIPAL MONEY MARKET PERFORM DURING THE FISCAL YEAR ENDED
AUGUST 31, 1999?

     California Municipal Money Market had a total return of 2.76%, which ranked
in the top 15% of the Lipper group. (See the previous page for additional fund
returns and performance comparisons.)

     The portfolio also provided more state and federal tax-free income than the
average California money fund. California Municipal Money Market's  7-day
effective yield on August 31, 1999, was 2.70%, while the average yield of the 51
California tax-exempt money market funds tracked by Lipper was 2.41%.

WHY DID CALIFORNIA MUNICIPAL MONEY MARKET OUTPERFORM ITS LIPPER GROUP?

     The key to the portfolio's solid relative performance was our
lower-than-average management fee. Other things being equal, lower expenses mean
higher yields and returns for our shareholders.

     Another reason the fund performed well was our ability to buy securities at
attractive yields and prices. We're able  to do that because we've developed
solid working relationships with securities dealers who offer very good rates on
California money market securities.

     We also made some good judgment calls about the market. For example, we
decided not to buy some notes issued early in June because of their low yields.
That turned out to be a good move because new issues came to market a few weeks
later offering yields 25 basis points higher. (A basis point equals 0.01%, so 25
basis points equal 0.25%.)

     In addition, California Municipal Money Market tends to hold a greater
percentage of securities subject to the federal alternative minimum tax (AMT)
than the other funds in the Lipper group.  AMT securities typically offer higher
yields than non-AMT notes.

CALIFORNIA MUNICIPAL MONEY MARKET'S YIELD INCREASED, PARTICULARLY IN THE PAST
SIX MONTHS. WHY?

     Money market yields rose primarily because the Federal Reserve raised
interest rates twice in the last six months to try to cool the economy and head
off potential inflation. In addition, the market expects at least one more rate
hike.

     But it's worth noting that yields on California money market securities are
low relative to national levels. That's because demand for California securities
is high, while supply is lower than in years past because California's strong
economy has reduced security issuance.

WHAT IS YOUR OUTLOOK FOR THE FUND?

     We'd like to extend the average maturity slightly by adding some
higher-yielding one-year securities. However, we'll likely hold off on extending
the fund's maturity until the difference in yield between California and
national notes returns to more normal levels.

Statements of Assets and Liabilities
- --------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as  securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results  in the fund's NET
ASSETS. The net assets divided by shares outstanding is the share price, or NET
ASSET VALUE PER SHARE. This statement also breaks down the fund's net assets
into capital (shareholder investments) and performance (investment income and
gains/losses).

AUGUST 31, 1999

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century California Tax-Free and Municipal Funds
(the trust) is registered under the Investment Company Act of 1940 as an
open-end management investment company. California Tax-Free Money Market Fund
(Tax-Free Money Market) and California Municipal Money Market Fund (Municipal
Money Market) (the funds) are two of the seven funds issued by the trust.
Tax-Free Money Market is diversified and Municipal Money Market is
non-diversified under the 1940 Act. The funds seek income that is exempt from
federal and California income taxes. Tax-Free Money Market and Municipal Money
Market seek to obtain as high a level of interest income as is consistent with
prudent investment management and conservation of shareholders' capital. The
funds concentrate their investments in a single state and therefore may have
more exposure to credit risk related to the state of California than a fund with
a broader geographical diversification. The following significant accounting
policies are in accordance with generally accepted accounting principles; these
principles may require the use of estimates by fund management.

    SECURITY VALUATIONS -- Portfolio securities are valued at amortized cost,
which approximates current market value. When valuations are not readily
available, securities are valued at fair value as determined in accordance with
procedures adopted by the Board of Trustees.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Interest income is recorded on the accrual basis and
includes accretion of discounts and amortization of premiums.

    INCOME TAX STATUS -- It is the funds' policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions from net investment income
are declared and credited daily and distributed monthly. The funds do not expect
to realize any long-term capital gains, and accordingly, do not expect to pay
any capital gains distributions. For the year ended August 31, 1999, 100%
(unaudited) of the funds' distributions from net investment income have been
designated as exempt from federal and California state income tax.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net gains and losses for financial statement and tax
purposes and may result in reclassification among certain capital accounts.

    At August 31, 1999, accumulated net realized capital loss carryovers for
Tax-Free Money Market of $274,509 (expiring in 2004 through 2007) and for
Municipal Money Market of $159,057 (expiring in 2003 through 2006) may be used
to offset future taxable gains.

    Tax-Free Money Market has elected to treat $12,510 of net capital losses
incurred in the ten month period ended August 31, 1999, as having been incurred
in the following fiscal year.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the trust's
distributor. Certain officers of FDI are also officers of the trust.

- --------------------------------------------------------------------------------
2. TRANSACTIONS WITH RELATED PARTIES

    The trust has entered into a Management Agreement with American Century
Investment Management, Inc. (ACIM), under which ACIM provides each fund with
investment advisory and management services in exchange for a single, unified
management fee. The Agreement provides that all expenses of the funds, except
brokerage, taxes, portfolio insurance, interest, fees and expenses of the
Trustees who are not considered "interested persons" as defined in the
Investment Company Act of 1940 (including counsel fees) and extraordinary
expenses, will be paid by ACIM. The fee is calculated daily and paid monthly. It
consists of an Investment Category Fee based on the average net assets of the
funds in a specific fund's investment category and a Complex Fee based on the
average net assets of all the funds managed by ACIM. The rates for the
Investment Category Fee range from 0.1570% to 0.2700% and the rates for the
Complex Fee range from 0.2900% to 0.3100%. For the year ended August 31, 1999,
the effective annual management fee for both funds was 0.50%.

    Certain officers and trustees of the trust are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the trust's investment manager, ACIM, and the
trust's transfer agent, American Century Services Corporation.

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees of the American Century California Tax-Free and Municipal Funds
and Shareholders of the California Tax-Free Money Market Fund and the California
Municipal Money Market Fund:

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the California Tax-Free Money
Market Fund and the California Municipal Money Market Fund (formerly the
American Century - Benham California Tax-Free Money Market Fund and the American
Century - Benham California Municipal Money Market Fund, respectively) (the
"Funds") at August 31, 1999, and the results of their operations for the year
then ended, the changes in their  net assets and the financial highlights for
each of the two years in the period then ended, in conformity with generally
accepted accounting principles. These financial statements and financial
highlights (hereafter referred to as "financial statements") are the
responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. The financial
highlights for each of the three years in the period ended August 31, 1997, were
audited by other auditors, whose report, dated October 3, 1997, expressed an
unqualified opinion on those statements. We conducted our audits of these
financial statements in accordance with generally accepted auditing standards,
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at August 31, 1999 by correspondence with the
custodian, provide a reasonable basis for the opinion expressed above.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers 38 fixed-income funds, ranging from money market
portfolios to long-term bond funds and including both taxable and tax-exempt
funds. Each is managed to provide a "pure play" on a specific sector of the
fixed-income market.

     To ensure adherence to this principle, the basic structure of each
portfolio is tied to a specific market index. Fund managers attempt to add value
by making modest portfolio adjustments based on their analysis of prevailing
market conditions.

     Investment decisions are made by management teams, which meet regularly to
discuss market analysis and investment strategies.

     In addition to these principles, each fund has its own investment policies:

     CALIFORNIA TAX-FREE MONEY MARKET and CALIFORNIA MUNICIPAL MONEY MARKET seek
to provide interest income exempt from both federal and California state income
taxes while maintaining a stable share price. The funds invest in high-quality
California municipal money market securities with remaining maturities of 13
months or less.

     An investment in these funds is neither insured nor guaranteed by the FDIC
or any other government agency. Yields will fluctuate, and although the funds
seek to preserve the value of your investment at $1 per share, it is possible to
lose money by investing in the funds.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objectives. Rankings are based on average annual
returns for each fund in a given category for the periods indicated. Rankings
are not included for periods less than one year.

     The Lipper category for the California Tax-Free Money Market and Municipal
Money Market is:

     CALIFORNIA TAX-EXEMPT MONEY MARKET FUNDS --funds that invest in
high-quality California municipal obligations with dollar-weighted average
maturities of less than 90 days.

CREDIT RATING GUIDELINES

     Credit quality (the issuer's financial strength and the likelihood of
timely payment of interest and principal) is a key factor in fixed-income
investment analysis. Credit ratings issued by independent rating and research
companies such as Standard & Poor's help quantify credit quality--the stronger
the issuer, the higher the credit rating. In turn, credit quality and ratings
greatly influence bond prices and yields--high ratings mean higher prices and
less current income (yield) as compensation for risk.

     But credit ratings are subjective.  They reflect the opinions of the rating
agencies that issue them and are not absolute standards of quality. Furthermore,
high credit ratings do not guarantee good investment performance. They do not
reflect the price stability of a municipal security when economic or market
conditions change.

Glossary
- --------------------------------------------------------------------------------

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year returns, please refer to the "Financial
Highlights" on pages 19-20.

YIELDS

* 7-DAY CURRENT YIELD is calculated based on the income generated by an
investment in the fund over a seven-day period and is expressed as an annual
percentage rate.

* 7-DAY EFFECTIVE YIELD is calculated similarly, although this figure is
slightly higher than the fund's 7-Day Current Yield because of the effects of
compounding. The 7-Day Effective Yield assumes that income earned from the
fund's investments is reinvested and generating additional income.

* 7-DAY TAX-EQUIVALENT YIELDS show the taxable yields that investors in a
combined California and federal income tax bracket would have to earn before
taxes to equal the fund's 7-Day Current Yield.

INVESTMENT TERMS

* BASIS POINT -- a basis point equals one one-hundredth of a percentage point
(or 0.01%). Therefore, 100 basis points equal one percentage point (or 1%).

STATISTICAL TERMINOLOGY

* NUMBER OF SECURITIES -- the number of entities that issued securities held by
a fund on a given date.

* WEIGHTED AVERAGE MATURITY (WAM) -- a measure of the sensitivity of a
fixed-income portfolio to interest rate changes. WAM indicates the average time
until the securities in the portfolio mature, weighted by dollar amount.

* EXPENSE RATIO -- the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.)

TYPES OF MUNICIPAL SECURITIES

* AMT PAPER -- instruments with income subject to the federal alternative
minimum tax.

* MUNICIPAL COMMERCIAL PAPER (CP) -- high-grade short-term securities backed by
a line of credit from a bank.

* MUNICIPAL NOTES -- securities with maturities of two years or less.

* PUT BONDS -- long-term securities that can be"put back" (i.e., sold at face
value) to a specified buyer at a prearranged date.

* VARIABLE-RATE NOTES -- securities that track market interest rates and

FUND CLASSIFICATIONS

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high price
fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds. Please be aware that the fund's category may change over
time. Therefore, it is important that you read a fund's prospectus or fund
profile carefully before investing to ensure its objectives, policies and risk
potential are consistent with your needs.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with
moderate price fluctuation risk.

* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price fluctuation risk.

Therefore, it is important that you read a fund's prospectus or fund profile
carefully before investing to ensure its objectives, policies and  risk
potential are consistent with your needs.For a definition of fund categories,
see the Glossary.

* While listed within the Income investment objective, the Target funds do not
  pay current dividend income. Income dividends are distributed once a year in
  December. The Target funds are listed in  all three risk categories due to the
  dramatic price volatility investors may experience during certain market
  conditions. If held to their target dates, however, they can offer a
  conservative, dependable way to invest for a specific time horizon.

Y2K TESTING EFFORTS PAY  DIVIDENDS IN PREPAREDNESS
- --------------------------------------------------------------------------------

Y2K, short for the Year 2000, refers more specifically to the date change from
December 31, 1999 to January 1, 2000. This date change is significant for
computers because many were originally programmed to process dates with
two-character years--99 instead of 1999.

When the calendar rolls to 2000, this can create problems for computers
programmed this way because they will read the date as "00," and may interpret
it as 1900. Most companies have been working to reprogram their computer systems
with four-digit years. Reprogramming is very labor-intensive and requires
testing to ensure that there are no errors and that all lines of  code were
successfully changed.

Recognizing the possible impact of the Y2K issue, our senior-level Steering
Committee,  programmers, business partners and Y2K team have been working
diligently to make  January 1, 2000 a non-event for American Century investors.

Currently, our systems have been modified, tested and returned to production,
and we have tested our systems with our vendors and business partners.

In March and April of this year, we participated in the Security Industry
Association's (SIA) industry-wide test and successfully processed transactions
for dates up to and beyond 2000. American Century transactions with our partner
firms were processed free of Y2K bugs. We also participated in the Market Data
Test conducted by the SIA and Financial Information Forum in May. Again, the
computer scripts were executed successfully with no Y2K-related errors.

In addition, our Y2K team has developed contingency plans. These plans are
designed to  minimize the impact on our investors and help us maintain
operations in the event of any  Y2K-related incidents. We have conducted
practice drills of contingency scenarios and will continue to refine our plans
during the rest of 1999 to respond quickly and effectively so that the date
change is as seamless as possible for investors. We expect the Year 2000 to be
business as usual at American Century.

     Strong economic growth, increasing inflation anxiety, and rising interest
rates set the tone for the U.S. bond market in 1999. These factors helped
determine the performance of American Century's California municipal funds for
the fiscal year ended August 31, 1999.

     Municipal bond funds enjoyed gains during the second half of 1998 when
interest rates fell and bond markets rallied. Those positive returns were
largely negated in 1999, however, as the recovery of overseas economies and
unabated U.S. growth reignited inflation fears and sent interest rates soaring.
While the Federal Reserve (the Fed--the U.S. central bank) saw fit to cut
short-term interest rates three times during the fall of 1998, the Fed raised
rates twice during the summer of 1999.

     Though market behavior and Fed interest rate policy swung from one extreme
to the other, one thing that remained remarkably consistent was the performance
of the American Century California municipal funds against their peers. All
seven of our California municipal money market and bond funds provided higher
tax-free yields and lower expenses than the average of their Lipper Inc. peer
groups. That's a hallmark of the American Century municipal investment approach.

     The strength of our municipal investment and credit research teams also
contributed to fund performance. The investment and credit teams, as well as
fund investors, have benefited from our commitment to build and maintain a
talented fund management group. American Century's entire investment management
team has doubled in size over the past three years.

     In addition to strengthening our portfolio and research staff, we've
recently made strategic investments in several other financial companies,
including Archipelago, Tradepoint Financial Networks, W.R. Hambrecht, and
WorldStreet Corporation. These investments demonstrate our active support of the
development and use of technologies that improve the efficiencies of capital
markets, lower trading costs, and ultimately offer better returns for
shareholders.

     One final note--in the spirit of our ongoing Year 2000 readiness
disclosures, we've provided a complete update on our preparations for Y2K on the
inside front cover of this report. We understand that our continued diligence in
this area is very important to you.

     As always, we appreciate your continued confidence in American Century.

Sincerely,
/s/James E. Stowers, Jr.                        /s/James E. Stowers III

Report Highlights
- --------------------------------------------------------------------------------

MARKET PERSPECTIVE

*   Municipal bond prices sagged under the weight of rising interest rates and
    weaker demand in the 12 months ended August 31, 1999.

*   A healthy U.S. economy, better growth overseas, and worries about inflation
    led the Federal Reserve to raise interest rates twice in 1999.

*   Short-term bonds, which are the least sensitive to rate changes, performed
    best, while intermediate- and longer-term securities had flat to negative
    returns.

CREDIT REVIEW

*   A healthy economy and state budget surplus led Standard & Poor's to upgrade
    California's credit rating.

*   California produced jobs faster than the national average, and the state's
    unemployment rate hit a nine-year low in August.

*   A key to California's economic health has been the "wealth effect"--
    household incomes and spending have been boosted by the big gains in
    housing prices and the stock market.

CALIFORNIA LIMITED-TERM TAX-FREE

*   The portfolio performed well--its return for the fiscal year ranked in the
    top quarter of the Lipper group.

*   The fund produced more tax-free income than the average California
    short-term fund, according to Lipper.

*   Two big reasons the portfolio outperformed the Lipper group were
    below-average expenses and good duration management.

*   We maintained the portfolio's high credit quality--we don't think
    lower-rated securities offer enough additional yield right now to justify
    taking added credit risk.

CALIFORNIA INTERMEDIATE-TERM TAX-FREE

*   The difficult environment for intermediate- and longer-term municipal bonds
    limited the portfolio's return.

*   California Intermediate-Term Tax-Free gave shareholders more tax-free income
    than the average California intermediate-term bond fund, according to
    Lipper.

*   We bought Puerto Rico bonds and securities that were out of favor with
    individual investors to boost the portfolio's yield without taking on any
    additional credit risk.

*   We're generally positive on the municipal market--credit quality is high,
    inflation is low, and municipal yields are attractive relative to
    Treasurys.

CALIFORNIA LONG-TERM TAX-FREE

*   Higher interest rates weighed on fund returns in 1999. The fund's long
    duration, which boosted performance when rates fell in 1998, limited
    returns this year.

*   The fund produced far more current income than the average California
    municipal fund, with a 30-day SEC yield in the top 5% of the peer group,
    according to Lipper.

*   We have a generally positive outlook for California municipal bonds--their
    yields are attractive relative to Treasurys, and we think we'll continue to
    see low inflation and modest economic growth.

*   We'll likely keep duration a little long while continuing to emphasize the
    same value-oriented approach that's helped the fund to its solid long-term
    performance.

Market Perspective from Randall W. Merk
- --------------------------------------------------------------------------------

Randall W. Merk, chief investment officer of fixed income

MUNICIPAL BOND PERFORMANCE

     Municipal bond prices came under pressure during the year ended August 31,
1999, as improving global economic conditions caused inflation anxiety. But the
fiscal year didn't begin that way. Bonds rallied in the second half of 1998 when
recessionary expectations surged due to financial crises in Asia, Russia, and
Latin America. The Federal Reserve (the Fed) bolstered the bond market when it
cut interest rates three times during the fall of 1998 to stem overseas problems
and shore up U.S. economic growth.

     Early 1999 brought evidence that the Fed's actions worked. The U.S. economy
remained robust, and Japan appeared on the mend. By the spring, recessionary
expectations gave way to inflation fears. Changing market sentiment and rate
hikes in June and August by the Fed pushed bond yields higher, taking their toll
on bond prices.

LONGER-TERM BONDS LAG

     Long-term bond yields rose the most and their prices dipped furthest, while
shorter-term bonds generally posted modest gains. (See the accompanying chart.)
Long-term bonds stumbled because of their greater interest rate sensitivity,
though falling demand also figured heavily in their losses.

     Bargain-hunting insurance companies--who had helped boost long-term
municipal bonds in the first half of the fiscal year--later turned their backs
on them. They gravitated instead to corporate bonds, which offered low prices
and attractive yields as companies swamped the market with new debt to avoid
potential fourth-quarter Year  2000 problems.

     Meanwhile, lower interest rate sensitivity and steady demand helped support
shorter-term bonds.

SECTOR OVERVIEW

     Although the strong economic environment created a stormy backdrop for
bonds, it contained a silver lining. Tax collections and municipal revenues in
California soared, boosting the creditworthiness of many municipal issuers in
the state.

     Among the biggest beneficiaries were land-based bonds, buoyed by the strong
real estate environment, and general obligation bonds, which are backed by tax
collections.

     Confidence in the economy and investors' appetite for higher yields were
reflected  in a narrowing yield gap between lower quality municipal bonds (those
rated BBB) and higher-rated (A to AAA) bonds, causing BBBs to outperform AAAs.

     On the flip side, interest rate-sensitive discount bonds--which sell below
face value--and hospital bonds performed poorly.

California Municipal Credit Review
- --------------------------------------------------------------------------------

     California's vibrant economy solidified municipal credit conditions during
the year ended August 31, 1999. A long list of positive economic data and a
favorable political climate spurred a credit upgrade for the state, which should
continue to benefit from its current strength for the next two or three years.

SUNNY ECONOMIC WEATHER

     By most accounts, several key segments of California's economy continued to
grow faster than the national average. In fact, California showed few signs of
the pain it was supposed to suffer due to the economic weakness of many of the
state's Pacific Rim trading partners.

     Instead, state unemployment hit a nine-year low of 5.1% in August, and the
2.8% rate of job growth outpaced the national average.  Personal bankruptcy
filings declined at twice the national average, house prices increased at nearly
double the national rate, and sales of existing single-family homes reached a
record pace.

     On top of that, with California's governor and assembly working in unison,
the state's budget--including a healthy surplus--was passed on time for the
first time in seven years.  Based on these improved financial and political
conditions, Standard & Poor's upgraded the state's general obligation bond
rating to AA- during the summer.

WHAT'S BEHIND THE GOLDEN GLOW

     While high-technology hardware businesses such as semiconductors struggled
with offshore competition, other areas such as software, multimedia,
biotechnology, and Internet-related businesses were very strong.

     Construction--notably in affordable housing in Central California--and
service industries have been particularly solid.  Plus, even though tourism
dollars from Asia dropped off as expected, California was able to take up the
slack by attracting tourists from inside the U.S.

     In addition, as much as 1% was added to California's growth rate by what is
known as the "wealth effect"--household income and spending increases due to the
bull market in stocks, the cashing in of stock options, and the sale of
single-family homes that have skyrocketed in value. The wealth effect was
particularly strong in Northern California.

CLOUDS ON THE HORIZON?

     Some observers believe California has reached a peak in its current
economic cycle. There are questions as to the sustainability of the wealth
effect due to the possibility of a stock market pullback caused by higher
interest rates and weaker corporate profits. In addition, rapidly increasing
property values have led to some consumer price inflation.

     However, we don't believe these influences will cause any near-term
problems in California. The state stands to benefit from any rebound in foreign
trade and the expansion of the Internet. Those are two of the key reasons why we
think that there are at least two or three years of economic strength ahead.

California Limited-Term Tax-Free--Q&A
- --------------------------------------------------------------------------------
[photo of Todd Pardula]

     An interview with Dave MacEwen and Todd Pardula (pictured above), portfolio
managers on the California Limited-Term Tax-Free fund investment team. Dave and
Todd--both experienced portfolio managers and members of the tax-free and
municipal funds team since the early 1990s--replaced Joel Silva, who left
American Century to pursue other opportunities.

HOW DID CALIFORNIA LIMITED-TERM TAX-FREE PERFORM DURING THE FISCAL YEAR ENDED
AUGUST 31, 1999?

     The fund performed well despite the difficult environment for bonds (see
the Market Perspective on page 3). For the 12 months ended August 31, 1999,
California Limited-Term Tax-Free returned 2.26%, which compares favorably with
the 1.62% average return of the 13 "California Short-Intermediate Municipal Debt
Funds" tracked by Lipper Inc. For the year, the fund's return ranked in the top
quarter of the Lipper group. The Lehman 3-Year Municipal Index returned 2.92%
for the same period. (See the previous page for other fund performance
comparisons).

WHY DID THE PORTFOLIO DO SO WELL RELATIVE TO THE LIPPER GROUP?

     One reason we beat our Lipper group average is that we did a good job of
managing the fund's duration. Duration measures a portfolio's sensitivity to
changes in interest rates. The shorter the duration, the less a fund's share
price fluctuates when rates change, while a longer duration means a fund is more
sensitive to rate changes. Ideally, you want a shorter duration when interest
rates are rising and a longer duration when rates are falling. Our relative
performance got a boost this year because we lengthened duration in late 1998,
when municipal bond rates were falling, and shortened duration this year, when
interest rates were rising.

     Another reason for the fund's solid relative performance is that our
expenses are below average. The fund's expense ratio on August 31 was 0.51%,
compared with a category average of 0.92% according to Lipper. Other things
being equal, lower expenses should mean higher yields and returns for our
shareholders.

WHAT OTHER STRATEGIES DID YOU USE TO BOOST THE FUND'S RETURN?

     We took advantage of the big difference in yield between bonds maturing in
2002-04 and bonds maturing in 2007-08. Longer-term municipal bonds typically
have higher yields than shorter-term securities to compensate for the extra risk
associated with interest rate uncertainty over a longer time frame.

     But the difference in yield can vary depending on supply and demand
factors. Demand from retail investors (which include individuals and brokers)
for higher-quality, shorter-term municipal bonds was very strong. That meant the
difference in yield between short- and intermediate-term bonds was greater than
usual.

     As a result, we sold some of our shorter-term bonds and bought more
attractively valued, higher-yielding bonds due in 2008. Making that trade
allowed us to collect premium prices on our shorter-term securities while
picking up significant extra yield on these intermediate-term securities.

California Limited-Term Tax-Free--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

CAN YOU GIVE AN EXAMPLE OF HOW ONE OF THESE TRADES WORKS IN PRACTICE?

     We recently purchased California general obligation bonds maturing in 2008
that yielded 4.80% and sold similar bonds due in 2003 with a yield of 4.08%.
That's 72 basis points (a basis point equals 0.01%, so 72 basis points equals
0.72%) in additional yield for going out five years in maturity, which we view
as a very attractive trade. Of course, we were limited in the extent to which we
could buy these intermediate-term securities because we didn't want to lengthen
the portfolio's duration significantly, given the prevailing interest rate
environment.

SPEAKING OF INTEREST RATES, HOW DOES CALIFORNIA LIMITED-TERM TAX-FREE'S YIELD
COMPARE?

     On August 31, the fund's 30-day SEC yield was 3.72%, while the average
yield of the Lipper group was 3.22%. The fund's 3.72% yield equates to a fully
taxable yield of 6.79% for California investors in the highest federal and state
tax brackets.

     The fund's yield is much higher than it was six months ago (when it was
3.03%). That's largely due to the general increase in municipal market interest
rates.

DID YOU MAKE ANY CHANGES TO TRY TO ADD YIELD TO THE PORTFOLIO?

     Yes, we added Puerto Rican bonds whose yields were a little higher than
those we could get on California municipal bonds with a similar maturity. (The
income from Puerto Rican bonds is free from state and federal taxes for
investors in all 50 states.)

     California municipal bond yields are below those of Puerto Rican bonds
because the demand for shorter-term California bonds has been extremely strong.
In addition, the supply of new bonds is down because higher interest rates have
made borrowing less attractive for municipal bond issuers. The result of lower
supply and higher demand is the same for any market: California municipal bond
prices are higher and their yields lower than would otherwise be the case.

HOW DID YOU MANAGE THE FUND'S CREDIT QUALITY?

     We maintained the portfolio's high average credit quality. We don't think
lower-rated bonds offer enough extra yield to justify taking on the additional
credit risk right now. The California economy is extremely strong, so credit
quality is up across the board. And in general, we don't see many BBB rated
bonds in our maturity sector, so credit quality hasn't been much of an issue
lately.

WHAT IS YOUR OUTLOOK FOR THE FUND?

     We will continue to look for opportunities to buy higher-yielding
intermediate-term bonds, as well as attractively priced new issues. We'll keep
selling shorter-term bonds at premium prices as long as demand from retail
investors remains stronger than usual. At the same time, we will position the
fund cautiously as we approach year-end, carefully managing the portfolio's

California Intermediate-Term Tax-Free--Q&A
- --------------------------------------------------------------------------------
[photo of Colleen Denzler]
     An interview with Colleen Denzler,  a portfolio manager on the California
Tax-Free and Municipal funds investment team.

HOW DID CALIFORNIA INTERMEDIATE-TERM  TAX-FREE PERFORM IN THE FISCAL YEAR ENDED
AUGUST 31, 1999?

     The fund's performance reflects the difficult investment climate for
municipal bonds so far in 1999 (see the Market Perspective on page 3). For the
fiscal year, California Intermediate-Term Tax-Free returned 0.74%. This compares
with the 0.69% average return of the  26 "California Intermediate Municipal Debt
Funds" tracked by Lipper Inc.  (See the previous page for additional performance
comparisons.)

HOW DID THE PORTFOLIO'S YIELD COMPARE?

     California Intermediate-Term Tax-Free produced more state and federal
tax-free income than the average California intermediate bond fund. On August
31, 1999, our fund had a 30-day SEC yield of 4.20%, while the Lipper group had
an average yield of 4.01%. The portfolio's 4.20% yield translates into a
tax-equivalent yield of 7.67% for an investor in the highest state and federal
tax brackets. That tax-equivalent yield compares  very favorably with the 6.07%
yield on the 30-year Treasury bond at the end  of August.

CAN YOU EXPLAIN THE PORTFOLIO'S PERFORMANCE FOR THE 12 MONTHS?

     The fiscal year is really a tale of two distinct periods. California
Intermediate-Term Tax-Free performed very well from late 1998 to early 1999,
when interest rates on municipal bonds fell. But returns were limited in recent
months as intermediate-term municipal bond yields rose.

     For example, a year ago, a five-year AAA municipal bond yielded 3.87%.  By
February, that yield was down to 3.70%. Bond prices and yields move in opposite
directions, so lower yields meant healthy returns for the fund. But municipal
bond yields rose for much  of 1999 and by August 31, five-year municipal bonds
were yielding 4.39%. Higher rates limited the fund's return in recent months.

HOW DID YOU MANAGE THE FUND'S EXPOSURE TO INTEREST RATE CHANGES?

     We use duration to measure a portfolio's sensitivity to changes in interest
rates. The longer a fund's duration, the more you gain when rates fall, and the
more you lose when rates rise. Conversely, a shorter duration means a bond
portfolio's price fluctuates less when rates change. So, ideally, you want to
lengthen duration when interest rates are falling and shorten duration when
rates are rising.

     Our duration was relatively long, at about 6.0 years, when municipal bond
rates were falling in late 1998 and early 1999. That longer duration helped the
fund's performance. But the strategy that worked well earlier in the year
limited returns in mid-1999, when interest rates rose sharply. As a result, we
started to rein in California Intermediate-Term  Tax-Free's duration, bringing
it down to about 5.7 years by August 31, 1999.

California Intermediate-Term Tax-Free--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

WHAT OTHER CHANGES DID YOU MAKE TO THE PORTFOLIO?

     We sold some securities to take advantage of supply and demand imbalances
in the California municipal market. The supply of new bonds is down in
California because the robust economy has boosted tax revenues, which reduces
the need for municipalities to borrow. Meanwhile, demand from individual
investors and brokerage firms surged.

     Individual investors typically buy high-quality short- and
intermediate-term bonds trading at par (a price equal to their face value).
Lower supply and higher demand made California par bonds attractive candidates
for sale. As  a result, we were able to lock in profits by selling some of these
bonds.

DID YOU MAKE ANY CHANGES TO TRY TO INCREASE THE FUND'S YIELD?

     Yes, we used the proceeds from the sale of these par bonds to buy
securities that were out of favor by individual investors, such as callable and
non-par bonds. Those trades helped us increase the fund's yield without taking
on any additional credit risk.

     In addition, we increased the portfolio's yield by adding Puerto Rican
bonds. (The income from Puerto Rican bonds is free from state and federal taxes
for investors in all 50 states.) Yields on Puerto Rican securities were a little
higher than those we could get on California municipal bonds with a similar
maturity. Again, that's because California municipal bond yields were depressed
by strong demand and limited supply.

WHAT'S YOUR OUTLOOK FOR THE CALIFORNIA MUNICIPAL MARKET?

     We're cautiously optimistic. State and local credit quality is good, and
inflation remains low. What's more, municipal bond yields are very attractive
relative to yields on fully taxable investments. In fact, municipal bonds are as
attractive relative to Treasury securities as they were at the height of the
Asian economic crisis last year--but we see no comparable risk this year. As a
result, we think municipal bonds represent very good values right now.

GIVEN THAT OUTLOOK, WHAT ARE YOUR PLANS FOR THE FUND GOING FORWARD?

     In terms of duration, we'll continue to position the fund a little more
conservatively than we did earlier in the year. In addition, we're likely to
keep the portfolio's credit quality relatively high. That's because we don't see
much yield advantage to taking on additional credit risk right now. We'll also
continue to take some profits by selling par bonds to brokers and individual
investors, while trying to find higher-yielding securities elsewhere in the
market.

California Long-Term Tax-Free--Q&A
- --------------------------------------------------------------------------------
[photo of Dave MacEwen]

     An interview with Dave MacEwen, a portfolio manager on the California
Tax-Free and Municipal funds investment team.

HOW DID CALIFORNIA LONG-TERM TAX-FREE PERFORM DURING ITS FISCAL YEAR ENDED
AUGUST 31, 1999?

     It was a disappointing year for both the municipal market and the fund.
California Long-Term Tax-Free posted a total return of -1.85%, which lagged the
- -1.49% average total return of its peer group--106 "California Municipal Debt
Funds" tracked by Lipper Inc. Despite this recent setback, the fund's
longer-term results remained solid. For the three-, five-, and 10-year periods
ended August 31, 1999, the fund consistently ranked in the top 40% of its peer
group.

     Additionally, California Long-Term Tax-Free produced more state and federal
tax-free income than its peers. The fund's 30-day SEC yield as of August 31,
1999, was 4.95%, compared with the 4.26% average yield of the Lipper peer group

     The portfolio's below-average expenses helped boost the fund's long-term
returns and its yield.

WHY DID THE FUND TRAIL ITS PEERS DURING THE PAST YEAR?

     As is the case from time to time, the strategy that helped us outperform in
one period hurt us in another. In this instance, California Long-Term Tax-Free's
duration--a measure of its interest rate sensitivity--was longer than the
average of its peers. (The longer a fund's duration, the more the share price
will rise or fall when interest rates change.)  This positioning helped
performance in 1998 when interest rates fell, but hurt the fund in 1999 when
rates rose.

CAN YOU EXPLAIN WHY YOU KEPT DURATION RELATIVELY LONG?

     Our decision to maintain a somewhat longer duration was based on our view
that interest rates would decline in 1999 in response to global economic
weakness. Given that outlook, we wanted to protect the fund from "reinvestment"
risk, which occurs when rates fall. Under those circumstances, municipalities
refinance older, higher-yielding bonds and potentially force bondholders to
reinvest the proceeds in newer bonds at lower interest rates.

     To guard against reinvestment risk, we used discount bonds. These bonds
trade below face value (par)--at a "discount"--because their interest payments
are below prevailing market interest rates. There's less incentive for issuers
to refinance--or "call"--discount bonds. That natural "call protection" means
the duration of discount bonds is relatively long to begin with. Unfortunately,
rising rates diminished the likelihood that discount bonds would be called, so
their lives extended further and their durations lengthened. That made the
portfolio even more sensitive to rising rates.

California Long-Term Tax-Free--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

WHAT CHANGES DID YOU MAKE IN RESPONSE TO RISING INTEREST RATES?

     Rather than sell discount bonds at distressed prices and abandon a strategy
we believe will ultimately help the fund, we chose another route. To prevent the
fund from becoming overly interest rate sensitive, we sold some par bonds at
relatively good prices and temporarily parked the proceeds in short-term
investments such as money market securities, which helped offset the
longer-maturity discount bonds.

     Rising rates and weak prices also gave us the opportunity to do some "tax
swapping." When it was advantageous to do so, we sold some of our
worst-performing bonds at a loss to offset capital gains incurred elsewhere in
the fund. The proceeds were used to buy higher-yielding bonds, which helped to
boost the fund's distribution yield.

     Finally, we increased our stake in BBB bonds. That helped performance
because BBB bonds held up relatively well.

WHAT'S THE ATTRACTION OF CERTIFICATES OF PARTICIPATION (COPS), THE FUND'S
LARGEST POSITION THROUGHOUT THE PERIOD?

     COPs originated in 1978 when California voters approved "Proposition 13."
That amendment put strict limits on the amount of money that could be raised
from property taxes and required two-thirds voter approval to sell new general
obligation bonds. Those restrictions helped COPs, which are an alternate form of
financing that don't require voter approval, become more popular.

     We're attracted to COPs because they are less well understood than other
bonds, which allows us to buy them at higher yields than comparably rated, more
familiar types of securities with similar maturities.

WHAT'S YOUR OUTLOOK FOR INTEREST RATES AND THE BOND MARKET?

     We're moderately bullish. The broad U.S. inflation gauges haven't changed
much recently, and there's evidence that the U.S. economy may be slowing.
Furthermore, we believe the Fed will remain sidelined for the balance of 1999 in
recognition of low inflation and out of concern for potential Y2K problems.

     Beyond the end of 1999, the outlook is less clear. It's quite feasible that
the tug-of-war between "good" (low inflation) and "evil" (tight labor markets
and wage pressures) will continue well into 2000. Ultimately, we think that
non-inflationary, moderate economic growth will win, providing a more favorable
backdrop for bonds. Because municipal bonds are currently priced attractively
relative to Treasury securities, we think municipals can be a prime beneficiary
of more favorable market sentiment.

GIVEN YOUR OUTLOOK, WHAT ARE YOUR PLANS FOR THE FUND OVER THE NEXT SIX MONTHS?

     As long as our outlook remains somewhat bullish, we're likely to maintain
our current duration position and emphasis on discount bonds. We'll also
continue working with our research staff to uncover attractively valued
securities, such as COPs, that have the potential to enhance returns. And we
plan to stick with the same value-oriented approach and below-average expenses
that have contributed to our long-term success.

Statements of Assets and Liabilities
- --------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as  securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results  in the fund's NET
ASSETS. The net assets divided by shares outstanding is the share price, or NET
ASSET VALUE PER SHARE. This statement also breaks down the fund's net assets
into capital (shareholder investments) and performance (investment income and
gains/losses).

AUGUST 31, 1999

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century California Tax-Free and Municipal Funds
(the trust) is registered under the Investment Company Act of 1940 as an
open-end management investment company. California Limited-Term Tax-Free Fund
(Limited-Term), California Intermediate-Term Tax-Free Fund (Intermediate-Term),
and California Long-Term Tax-Free Fund (Long-Term) (the funds) are three of the
seven funds issued by the trust. The funds are diversified under the 1940 Act.
The funds seek to obtain as high a level of interest income exempt from federal
and California income taxes as is consistent with prudent investment management
and conservation of shareholders' capital. The funds invest primarily in
municipal obligations with maturities based on each fund's investment objective.
The funds concentrate their investments in a single state and therefore may have
more exposure to credit risk related to the state of California than a fund with
a broader geographical diversification. The following significant accounting
policies are in accordance with generally accepted accounting principles; these
principles may require the use of estimates by fund management.

    SECURITY VALUATIONS -- Portfolio securities are valued through a commercial
pricing service or at the mean of the most recent bid and asked prices. When
valuations are not readily available, securities are valued at fair value as
determined in accordance with procedures adopted by the Board of Trustees.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Interest income is recorded on the accrual basis and
includes accretion of discounts and amortization of premiums.

    INCOME TAX STATUS -- It is the funds' policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions from net investment income
are declared daily and distributed monthly. Distributions from net realized
gains are declared and paid annually. For the year ended August 31, 1999, 100%
(unaudited) of the funds' distributions from net investment income have been
designated as exempt from federal and California state income tax.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

    At August 31, 1999, accumulated net realized capital loss carryovers of
$445,336 for Limited-Term (expiring in 2004) may be used to offset future
taxable gains.

    FUTURES CONTRACTS -- Each fund may buy and sell interest rate futures
contracts relating to debt securities. Each fund may use futures transactions to
maintain cash reserves while remaining fully invested, to facilitate trading, to
reduce transaction costs, or to pursue higher investment returns when a futures
contract is priced more attractively than its underlying security or index. One
of the risks of entering into futures contracts may include the possibility that
the changes in value of the contract may not correlate with the changes in value
of the underlying securities. Upon entering into a futures contract, the funds
are required to deposit either cash or securities in an amount equal to a
certain percentage of the contract value (initial margin). Subsequent payments
(variation margin) are made or received daily, in cash, by the funds. The
variation margin is equal to the daily change in the contract value and is
recorded as an unrealized gain or loss. The funds recognize a realized gain or
loss when the contract is closed or expires. Net realized and unrealized gains
or losses occurring during the holding period of futures contracts are a
component of realized gain (loss) on investments and unrealized appreciation
(depreciation) on investments, respectively. There were no open futures
contracts at August 31, 1999.

     ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the trust's
distributor. Certain officers of FDI are also officers of the trust.

2. TRANSACTIONS WITH RELATED PARTIES

    The trust has entered into a Management Agreement with American Century
Investment Management, Inc. (ACIM), under which ACIM provides each fund with
investment advisory and management services in exchange for a single, unified
management fee. The Agreement provides that all expenses of the funds, except
brokerage, taxes, portfolio insurance, interest, fees and expenses of the
Trustees who are not considered "interested persons" as defined in the
Investment Company Act of 1940 (including counsel fees) and extraordinary
expenses, will be paid by ACIM. The fee is calculated daily and paid monthly. It
consists of an Investment Category Fee based on the average net assets of the
funds in a specific fund's investment category and a Complex Fee based on the
average net assets of all the funds managed by ACIM. The rates for the
Investment Category Fee range from 0.1625% to 0.2800% and the rates for the
Complex Fee range from 0.2900% to 0.3100%. For the year ended August 31, 1999,
the effective annual management fee was 0.51%, for Limited-Term,
Intermediate-Term, and Long-Term.

    Certain officers and trustees of the trust are also officers and/or
directors, and, as a group, controlling stockholders of American Century
Companies, Inc., the parent of the trust's investment manager, ACIM, and the
trust's transfer agent, American Century Services Corporation.

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees of the American Century California Tax-Free and Municipal Funds
and  Shareholders of the California Limited-Term Tax-Free Fund, the California
Intermediate-Term  Tax-Free Fund and the California Long-Term Tax-Free Fund:

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the California Limited-Term
Tax-Free Fund, the California Intermediate-Term Tax-Free Fund and the California
Long-Term Tax-Free Fund (formerly the American Century - Benham California
Limited-Term Tax-Free Fund, the American Century - Benham California
Intermediate-Term Tax-Free Fund and the American Century - Benham California
Long-Term Tax-Free Fund, respectively) (the "Funds") at August 31, 1999, and the
results of their operations for the year then ended, the changes in their net
assets and the financial highlights for each of the two years in the period then
ended, in conformity with generally accepted accounting principles. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Funds' management; our
responsibility is to express an opinion on these financial statements based on
our audits. The financial highlights for each of the three years in the period
ended August 31, 1997, were audited by other auditors, whose report, dated
October 3, 1997, expressed an unqualified opinion on those statements. We
conducted our audits of these financial statements in accordance with generally
accepted auditing standards, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at August 31, 1999 by
correspondence with the custodian and brokers and the application of alternative
auditing procedures where confirmations from brokers were not received, provide
a reasonable basis for the opinion expressed above.

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers 38 fixed-income funds, ranging from money market
portfolios to long-term bond funds and including both taxable and tax-exempt
funds. Each is managed to provide a "pure play" on a specific sector of the
fixed-income market.

     To ensure adherence to this principle, the basic structure of each
portfolio is tied to a specific market index. Fund managers attempt to add value
by making modest portfolio adjustments based on their analysis of prevailing
market conditions.

     Investment decisions are made by management teams, which meet regularly to
discuss market analysis and investment strategies.

     In addition to these principles, each fund has its own investment policies

     CALIFORNIA LIMITED-TERM TAX-FREE seeks interest income exempt from both
federal and California state income taxes. The fund invests primarily in
California municipal securities and maintains a weighted average maturity of
five years or less.

     CALIFORNIA INTERMEDIATE-TERM TAX-FREE seeks interest income exempt from
both federal and California state income taxes. The fund invests primarily in
California municipal securities and maintains a weighted average maturity of
5-10 years.

     CALIFORNIA LONG-TERM TAX-FREE seeks interest income exempt from federal and
California state income taxes. The fund invests primarily in California
municipal securities and maintains a weighted average maturity of 10 years or
more.

COMPARATIVE INDICES

     The following indices are used in the report for fund performance
comparisons. They are not investment products available for purchase.

     The LEHMAN BROTHERS 3-YEAR MUNICIPAL BOND INDEX is composed of more than
4,000 municipal bonds with maturities of 2-4 years. The average credit rating of
the securities in the index is AA1/AA2. The index's average maturity is 3 years

     The LEHMAN BROTHERS 5-YEAR GENERAL OBLIGATION (GO) INDEX is composed of
more than 5,000 municipal bonds with maturities of 4-6 years. The average credit
rating of the securities in the index is AA1/AA2. The index's average maturity
is approximately 5 years.

     The LEHMAN BROTHERS LONG-TERM MUNICIPAL BOND INDEX is composed of more than
2,800 municipal bonds with maturities greater than 22 years. The average credit
rating of the securities in the index is AA2/AA3. The index's average maturity
is approximately 27 years.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objectives. Rankings are based on average annual
returns for each fund in a given category for the periods indicated. Rankings
are not included for periods less than one year.

     CALIFORNIA SHORT-INTERMEDIATE MUNICIPAL DEBT FUNDS (Limited-Term Tax-Free)
- -- funds that invest at least 65% of assets in municipal debt issues that are
exempt from taxation in California with dollar-weighted average maturities of
1-5 years.

     CALIFORNIA INTERMEDIATE MUNICIPAL DEBT FUNDS (Intermediate-Term Tax-Free)
- -- funds that invest at least 65% of assets in municipal debt issues that are
exempt from taxation in California with dollar-weighted average maturities of

CREDIT RATING GUIDELINES

    CREDIT RATINGS ARE ISSUED BY INDEPENDENT RESEARCH COMPANIES SUCH AS STANDARD
& POOR'S AND MOODY'S. THEY ARE BASED ON AN ISSUER'S FINANCIAL STRENGTH AND
ABILITY TO PAY INTEREST AND PRINCIPAL IN A TIMELY MANNER.

    SECURITIES RATED AAA, AA, A, OR BBB ARE CONSIDERED "INVESTMENT-GRADE"
SECURITIES, MEANING THEY ARE RELATIVELY SAFE FROM DEFAULT. HERE ARE THE MOST
COMMON CREDIT RATINGS AND THEIR DEFINITIONS:

*   AAA--EXTREMELY STRONG ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   AA--VERY STRONG ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   A--STRONG ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   BBB--GOOD ABILITY TO MEET FINANCIAL OBLIGATIONS.

    IT'S IMPORTANT TO NOTE THAT CREDIT RATINGS ARE SUBJECTIVE, REFLECTING THE
OPINIONS OF THE RATING AGENCIES; THEY ARE NOT ABSOLUTE STANDARDS OF QUALITY.

Glossary
- --------------------------------------------------------------------------------

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. (For fiscal year-by-year returns, please refer to the "Financial
Highlights" on pages 31-33.)

YIELDS

* 30-DAY SEC YIELD represents net investment income earned by the fund over a
30-day period, expressed as an annual percentage rate based on the fund's share
price at the end of the 30-day period. The SEC yield should be regarded as an
estimate of the fund's rate of investment income, and it may not equal the
fund's actual income distribution rate, the income paid to a shareholder's
account, or the income reported in the fund's financial statements.

* TAX-EQUIVALENT YIELDS show the taxable yields that investors in a combined
California and federal income tax bracket would have to earn before taxes to
equal the fund's tax-free yield.

INVESTMENT TERMS

* BASIS POINT -- one one-hundredth of a percentage point (or 0.01%). Therefore,
100 basis points equal one percentage point (or 1%).

* YIELD CURVE -- a graphic representation of the relationship between maturity
and yield for fixed-income securities.


STATISTICAL TERMINOLOGY

* NUMBER OF SECURITIES -- the number of different securities held by a fund on a
given date.

* WEIGHTED AVERAGE MATURITY (WAM) -- a measure of the sensitivity of a
fixed-income portfolio to interest rate changes. WAM indicates the average time
until the securities in the portfolio mature, weighted by dollar amount.

* AVERAGE DURATION -- a time-weighted average of the interest and principal
payments of the securities in a portfolio. As the duration of a portfolio
increases, so does the impact of a change in interest rates on the value of the
portfolio.

* EXPENSE RATIO -- the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.)

TYPES OF MUNICIPAL SECURITIES

* COPS (CERTIFICATES OF PARTICIPATION)/ LEASES --securities issued to finance
public property improvements (such as city halls and police stations) and
equipment purchases. Certificates of participation represent long-term debt
obligations, but leases have a higher risk profile because they require annual
appropriation.

* GO (GENERAL OBLIGATION) BONDS -- securities backed by the taxing power of the
issuer.

* LAND-SECURED BONDS -- securities such as Mello-Roos bonds and 1915 Act bonds
that are issued to finance real estate development projects.

* PREREFUNDED/ETM BONDS -- securities refinanced or escrowed to maturity by the
issuer because of their premium coupons (higher-than-market interest rates).
These bonds tend to have higher credit ratings because they are backed by
Treasury securities.

* REVENUE BONDS -- securities backed by revenues from sales taxes or from a
specific project, system, or facility (such as a hospital, electric utility, or
water system).

FUND CLASSIFICATIONS

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high price
fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds. Please be aware that the fund's category may change over
time. Therefore, it is important that you read a fund's prospectus or fund
profile carefully before investing to ensure its objectives, policies and risk
potential are consistent with your needs.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with
moderate price fluctuation risk.

* AGGRESSIVE -- these funds generally provide high return potential with
corresponding high price fluctuation risk.

* While listed within the Income investment objective, the Target funds do not
  pay current dividend income. Income dividends are distributed once a year in
  December. The Target funds are listed in  all three risk categories due to the
  dramatic price volatility investors may experience during certain market
  conditions. If held to their target dates, however, they can offer a
  conservative, dependable way to invest for a specific time horizon.

Y2K TESTING EFFORTS PAY  DIVIDENDS IN PREPAREDNESS
- --------------------------------------------------------------------------------

Y2K, short for the Year 2000, refers more specifically to the date change from
December 31, 1999 to January 1, 2000. This date change is significant for
computers because many were originally programmed to process dates with
two-character years--99 instead of 1999.

When the calendar rolls to 2000, this can create problems for computers
programmed this way because they will read the date as "00," and may interpret
it as 1900. Most companies have been working to reprogram their computer systems
with four-digit years. Reprogramming is very labor-intensive and requires
testing to ensure that there are no errors and that all lines of  code were
successfully changed.

Recognizing the possible impact of the Y2K issue, our senior-level Steering
Committee,  programmers, business partners and Y2K team have been working
diligently to make  January 1, 2000 a non-event for American Century investors.

Currently, our systems have been modified, tested and returned to production,
and we have tested our systems with our vendors and business partners.

In March and April of this year, we participated in the Security Industry
Association's (SIA) industry-wide test and successfully processed transactions
for dates up to and beyond 2000. American Century transactions with our partner
firms were processed free of Y2K bugs. We also participated in the Market Data
Test conducted by the SIA and Financial Information Forum in May. Again, the
computer scripts were executed successfully with no Y2K-related errors.

In addition, our Y2K team has developed contingency plans. These plans are
designed to  minimize the impact on our investors and help us maintain
operations in the event of any  Y2K-related incidents. We have conducted
practice drills of contingency scenarios and will continue to refine our plans
during the rest of 1999 to respond quickly and effectively so that the date
change is as seamless as possible for investors. We expect the Year 2000 to be
business as usual at American Century.

     Strong economic growth, increasing inflation anxiety, and rising interest
rates set the tone for the U.S. bond market in 1999. These factors helped
determine the performance of American Century's California municipal funds for
the fiscal year ended August 31, 1999.

     Municipal bond funds enjoyed gains during the second half of 1998 when
interest rates fell and bond markets rallied. Those positive returns were
largely negated in 1999, however, as the recovery of overseas economies and
unabated U.S. growth reignited inflation fears and sent interest rates soaring.
While the Federal Reserve (the Fed--the U.S. central bank) saw fit to cut
short-term interest rates three times during the fall of 1998, the Fed raised
rates twice during the summer of 1999.

     Though market behavior and Fed interest rate policy swung from one extreme
to the other, one thing that remained remarkably consistent was the performance
of the American Century California municipal funds against their peers. All
seven of our California municipal money market and bond funds provided higher
tax-free yields and lower expenses than the average of their Lipper Inc. peer
groups. That's a hallmark of the American Century municipal investment approach.

     The strength of our municipal investment and credit research teams also
contributed to fund performance. The investment and credit teams, as well as
fund investors, have benefited from our commitment to build and maintain a
talented fund management group. American Century's entire investment management
team has doubled in size over the past three years.

     In addition to strengthening our portfolio and research staff, we've
recently made strategic investments in several other financial companies,
including Archipelago, Tradepoint Financial Networks, W.R. Hambrecht, and
WorldStreet Corporation. These investments demonstrate our active support of the
development and use of technologies that improve the efficiencies of capital
markets, lower trading costs, and ultimately offer better returns for
shareholders.

     One final note--in the spirit of our ongoing Year 2000 readiness
disclosures, we've provided a complete update on our preparations for Y2K on the
inside front cover of this report. We understand that our continued diligence in
this area is very important to you.

     As always, we appreciate your continued confidence in American Century.

Sincerely,
/s/James E. Stowers, Jr.                        /s/James E. Stowers III

Report Highlights
- --------------------------------------------------------------------------------

MARKET PERSPECTIVE

*   Municipal bond prices sagged under the weight of rising interest rates and
    weaker demand in the year ended August 31, 1999.

*   A healthy U.S. economy, better growth overseas, and worries about inflation
    led the Federal Reserve to raise interest rates twice in 1999.

*   Short-term bonds, which are least sensitive to rate changes, performed best,
    while intermediate- and longer-term securities had flat to negative
    returns.

CREDIT REVIEW

*   A healthy economy and state budget surplus led Standard & Poor's to upgrade
    California's credit rating.

*   California produced jobs faster than the national average, and the state's
    unemployment rate hit a nine-year low in August.

*   A key to California's economic health has been the "wealth
    effect"--household incomes and spending have been boosted by the big gains
    in housing prices and the stock market.

CALIFORNIA HIGH-YIELD MUNICIPAL

*   California High-Yield Municipal continued to perform very well against its
    peers. Its fiscal year performance put it in the top 5% of its Lipper peer
    group. (See page 5 for standardized ranking information.)

*   However, like most other U.S. bond funds, its one-year returns were low.
    Rising interest rates put downward pressure on bond prices.

*   The portfolio performed well versus similar funds for two important reasons.
    First, it was less sensitive  (as measured by duration) to rising interest
    rates. Second, it held a relatively large position in unrated bonds, which
    generally outperformed other municipal securities.

*   This fund typically focuses much more on high-yielding, undervalued
    securities than on changing its interest rate sensitivity. We plan to
    continue this long-term value strategy  as long as the California economy
    remains strong

CALIFORNIA INSURED TAX-FREE

*   Higher interest rates weighed on fund returns in 1999. The fund's
    relatively long duration, which boosted performance when interest rates
    fell in 1998, limited returns this year.

*   The fund produced more current income than the average California insured
    municipal fund, with a  30-day SEC yield in the top 11% of the peer group,
    according to Lipper.

*   We have a generally positive outlook for California municipal bonds--their
    yields are attractive relative to Treasurys, and we think we'll continue to
    see low inflation and modest economic growth.

*   We'll likely keep duration a little long while continuing to emphasize the
    same value-oriented approach that's helped the fund to its solid long-term
    performance.

Market Perspective from Randall W. Merk

MUNICIPAL BOND PERFORMANCE

     Municipal bond prices came under pressure during the year ended August 31,
1999, as improving global economic conditions caused inflation anxiety. But the
fiscal year didn't begin that way. Bonds rallied in the second half of 1998 when
recessionary expectations surged due to financial crises in Asia, Russia, and
Latin America. The Federal Reserve (the Fed) bolstered the bond market when it
cut interest rates three times during the fall of 1998 to stem overseas problems
and shore up U.S. economic growth.

     Early 1999 brought evidence that the Fed's actions worked. The U.S. economy
remained robust, and Japan appeared on the mend. By the spring, recessionary
expectations gave way to inflation fears. Changing market sentiment and rate
hikes in June and August by the Fed pushed bond yields higher, taking their toll
on bond prices.

LONGER-TERM BONDS LAG

     Long-term bond yields rose the most and their prices dipped furthest, while
shorter-term bonds generally posted modest gains. (See the accompanying chart.)
Long-term bonds stumbled because of their greater interest rate sensitivity,
though falling demand also figured heavily in their losses.

     Bargain-hunting insurance companies--who had helped boost long-term
municipal bonds in the first half of the fiscal year--later turned their backs
on them. They gravitated instead to corporate bonds, which offered low prices
and attractive yields as companies swamped the market with new debt to avoid
potential fourth-quarter Year  2000 problems.

     Meanwhile, lower interest rate sensitivity and steady demand helped support
shorter-term bonds.

SECTOR OVERVIEW

     Although the strong economic environment created a stormy backdrop for
bonds, it contained a silver lining. Tax collections and municipal revenues in
California soared, boosting the creditworthiness of many municipal issuers in
the state.

     Among the biggest beneficiaries were land-based bonds, buoyed by the strong
real estate environment, and general obligation bonds, which are backed by tax
collections.

     Confidence in the economy and investors' appetite for higher yields were
reflected  in a narrowing yield gap between lower quality municipal bonds (those
rated BBB) and higher-rated (A to AAA) bonds, causing BBBs to outperform AAAs.

     On the flip side, interest rate-sensitive discount bonds--which sell below
face value--and hospital bonds performed poorly.

California Municipal Credit Review
- --------------------------------------------------------------------------------

     California's vibrant economy solidified municipal credit conditions during
the year ended August 31, 1999. A long list of positive economic data and a
favorable political climate spurred a credit upgrade for the state, which should
continue to benefit from its current strength for the next two or three years.

SUNNY ECONOMIC WEATHER

     By most accounts, several key segments of California's economy continued to
grow faster than the national average. In fact, California showed few signs of
the pain it was supposed to suffer due to the economic weakness of many of the
state's Pacific Rim trading partners.

     Instead, state unemployment hit a nine-year low of 5.1% in August, and the
2.8% rate of job growth outpaced the national average.  Personal bankruptcy
filings declined at twice the national average, house prices increased at nearly
double the national rate, and sales of existing single-family homes reached a
record pace.

     On top of that, with California's governor and assembly working in unison,
the state's budget--including a healthy surplus--was passed on time for the
first time in seven years.  Based on these improved financial and political
conditions, Standard & Poor's upgraded the state's general obligation bond
rating to AA- during the summer.

WHAT'S BEHIND THE GOLDEN GLOW

     While high-technology hardware businesses such as semiconductors struggled
with offshore competition, other areas such as software, multimedia,
biotechnology, and Internet-related businesses were very strong.

     Construction--notably in affordable housing in Central California--and
service industries have been particularly solid.  Plus, even though tourism
dollars from Asia dropped off as expected, California was able to take up the
slack by attracting tourists from inside the U.S.

     In addition, as much as 1% was added to California's growth rate by what is
known as the "wealth effect"--household income and spending increases due to the
bull market in stocks, the cashing in of stock options, and the sale of
single-family homes that have skyrocketed in value. The wealth effect was
particularly strong in Northern California.

CLOUDS ON THE HORIZON?

     Some observers believe California has reached a peak in its current
economic cycle. There are questions as to the sustainability of the wealth
effect due to the possibility of a stock market pullback caused by higher
interest rates and weaker corporate profits. In addition, rapidly increasing
property values have led to some consumer price inflation.

     However, we don't believe these influences will cause any near-term
problems in California. The state stands to benefit from any rebound in foreign
trade and the expansion of the Internet. Those are two of the key reasons why we
think that there are at least two or three years of economic strength ahead.

California High-Yield Municipal--Q&A
- --------------------------------------------------------------------------------
[photo of Steven Permut]

     An interview with Steven Permut, a portfolio manager on the California
Tax-Free and Municipal funds investment team.

HOW DID CALIFORNIA HIGH-YIELD MUNICIPAL PERFORM DURING ITS FISCAL YEAR ENDED
AUGUST 31, 1999?

     California High-Yield Municipal continued to perform very well against its
peers. The fund returned 0.26%, compared with the -1.49% average total return of
the 106 "California Municipal Debt Funds" tracked by Lipper Inc.

     That performance put the portfolio in the top 5% of the Lipper group for
the fiscal year. In addition, for the key long-term performance periods ended
August 31, 1999, California High-Yield Municipal consistently placed in the top
10% of its peer group.

     But that can't obscure the fact that 1999 has been a difficult year for
bonds. As a result, the fund's absolute returns, like the returns for most U.S.
bond funds during the period, were low. But on the bright side, the portfolio
provided a very attractive 30-day SEC yield. As of August 31, 1999, the SEC
yield was 5.12%, compared with the 4.26% average yield of the Lipper group.

WHAT HELPED BOOST CALIFORNIA HIGH-YIELD MUNICIPAL'S PERFORMANCE?

     Two important factors. The portfolio's duration--a measure of its
sensitivity to changes in interest rates--was shorter than the average duration
of its peers. That meant that California High-Yield Municipal was hurt less as
interest rates rose during the period. In addition, the fund held a more
substantial weighting in higher-yielding unrated bonds than most of its
competitors. These bonds provided superior performance.

WHAT SPURRED THE SUPERIOR PERFORMANCE OF UNRATED BONDS?

     At the beginning of the period, there was concern about continued economic
weakness in Asia and its impact on California's economy. Bonds of low credit
quality, including unrated bonds, suffered from this anxiety. However, the Asian
problems did not hurt the California economy as much as expected, and we never
saw a weakening in the prospects for our unrated holdings.

     As unrated bonds held their value, the yield differential between unrated
and rated California municipal bonds narrowed significantly when interest rates
rose. Unrated bonds basically enjoyed an increase in value relative to rated
securities. By overweighting unrated bonds--our unrated bond holdings increased
from 45% to 57% of the portfolio over the past six months--and using our
experienced credit team to help us avoid credit problems, California High-Yield
Municipal outpaced most of its competition.

AMONG UNRATED SECURITIES, WHAT WERE THE MOST IMPORTANT SECTORS?

     Land-secured bonds were fertile ground for us. This is a sector that we've
continually overweighted relative to its representation in the California
municipal market. On August 31, 1999, land-secured deals made up about 3-4% of
the market. The portfolio, on the other hand, had 33% of its assets invested in
land-secured investments, with an additional 10% in housing revenue bonds.

     Land-secured bonds are typically issued to support residential or
commercial real estate development. As the land is developed and ownership
diversifies, the credit risk diminishes. There's less chance that one
participant's credit problems will keep bondholders from receiving timely
interest and principal payments, and the credit quality of the land-secured
bonds improves. So do their prices, and that's when we typically sell the bonds.

     Land-secured bonds performed particularly well because of the strength of
the California economy and a dramatic increase in property values. Within this
sector, we focused primarily on affordable single-family residential districts
in some of the economically healthier regions of the state, such as the San
Francisco Bay Area, Sacramento, southern Orange County and northern San Diego
County.

WHAT ARE THE POTENTIAL RISKS ASSOCIATED WITH DEDICATING SUCH A LARGE PART OF THE
PORTFOLIO TO LAND-SECURED BONDS?

     If the economy were to weaken, real estate would be one of the first
sectors that would be hurt. Therefore, it's clearly a sector to overweight only
in a period of strong or improving credit quality.  If economic problems
appeared, we would try to reduce our holdings in land-secured bonds,
particularly those issued by districts in the early stages of development. We'd
also likely increase holdings in essential service revenue bonds, which are
typically least affected by the economic cycle.

     In addition, it's important to remember two factors. First, we benefit from
the local expertise of our municipal credit analysts, which helps them pick
promising investments, watch over them, and sell them if problems arise. Second,
our credit expertise spills into other unrated areas that have provided
significant yield and benefited the portfolio, including hotels, mobile home
parks, healthcare facilities for the elderly, and hospitals.

AS 1999 WINDS DOWN, WHAT IS YOUR INTEREST RATE OUTLOOK AND HOW WILL THAT AFFECT
YOUR STRATEGY?

     Inflation still appears to be under control, and there's evidence that the
U.S. economy may be slowing. But the outlook remains murky--interest rates could
continue to rise as investors react to economic reports perceived as potentially
inflationary, or to saber rattling by the Fed.

     Looking at portfolio strategy, we intend to keep California High-Yield
Municipal's duration neutral, avoiding a significant bet on the direction of
interest rates. Instead, we'll aim to add value through our security selection
process, picking the bonds we think have the best long-term credit fundamentals
and offer the most appealing yields. This is the same strategy that has been
consistently successful for us.

California Insured Tax-Free--Q&A
- --------------------------------------------------------------------------------
[photo of Dave MacEwen]
     An interview with Dave MacEwen, a portfolio manager on the California
Tax-Free and Municipal funds investment team.

HOW DID CALIFORNIA INSURED TAX-FREE PERFORM DURING THE FISCAL YEAR ENDED AUGUST
31, 1999?

     The fund's performance reflected the difficulties the municipal bond market
faced. California Insured Tax-Free returned -1.71%, which lagged the -1.45%
average total return of its peer group--23 "California Insured Municipal Debt
Funds" tracked by Lipper Inc.

     Even with the recent disappointing performance, the fund's longer-term
record remained compelling. For the three- and five-year periods ended August
31, 1999, the fund consistently ranked in the top third of its peer group.

     Additionally, California Insured Tax-Free produced more current income than
its peers. The fund's 30-day SEC yield as of August 31, 1999, was 4.73%,
compared with the 4.01% average yield of the Lipper group.

     The fund's strong yield and long-term returns can be attributed in part to
below-average expenses. Other things being equal, lower expenses mean higher
yields and returns for shareholders.

WHAT FACTORS CAUSED THE FUND TO LAG ITS PEERS DURING THE PAST YEAR?

     The main factor was the fund's increased interest rate sensitivity,
measured by its somewhat long duration relative to its peers. (The longer a
fund's duration, the more the share price will rise and fall in response to
interest  rate changes.)

     In August 1998, our outlook called  for falling interest rates in response
to global economic weakness. To capture more of the anticipated gains resulting
from declining rates, we focused on discount bonds. These bonds trade below face
value (par)--at a discount--because their interest coupons are below prevailing
market interest rates.

     When interest rates declined in 1998, the fund's somewhat longer duration
and focus on discount bonds gave it an advantage over its peers. But when rates
began to move higher in 1999, those same factors hurt performance.

WHAT MADE DISCOUNT BONDS SO SUSCEPTIBLE TO RISING INTEREST RATES?

     A bond's price and duration reflect in part the likelihood that it will be
called (refinanced) by its issuer before maturity. If it appears likely that a
bond is in jeopardy of being called, investors tend to push its price lower
because they don't relish the prospect of being forced to forfeit
higher-yielding bonds and reinvest at lower rates. At the same time, the bond's
duration shortens.

     Because their interest coupons are below prevailing interest rates,
discount bonds are generally the last bonds to be refinanced. That "call

California Insured Tax-Free--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

protection" means the duration of discount bonds is relatively long compared
with higher-coupon bonds, and that their duration lengthens when rates rise.
Their heightened sensitivity to rising interest rates--coupled with diminished
demand for call-protection--caused discount bonds to perform poorly during 1999.

WHAT CHANGES IN STRATEGY DID YOU MAKE DURING THE YEAR?

     We didn't want to sell discount bonds at distressed prices or abandon a
strategy we believe could ultimately serve the fund well. So to keep the fund
from becoming overly interest rate sensitive, we began to "barbell" the
portfolio, increasing our holdings in short-term investments such as cash to
help offset long-duration discount bonds.

     In addition, we sold some of our worst-performing bonds at a loss to offset
capital gains incurred elsewhere in the portfolio. We invested the proceeds in
higher-yielding bonds, which helped boost the fund's distribution yield.

IN TERMS OF SECTORS, WHAT CHOICES DID  YOU MAKE?

     One area of emphasis was certificates of participation (COPs). As a quick
review, you may recall that COPs originated in 1978 when California voters
approved "Proposition 13." That amendment put strict limits on the amount of
money that could be raised from property taxes and required two-thirds voter
approval by the issuing jurisdiction to sell new general obligation bonds. Those
restrictions helped COPs, which are an alternate form of financing that don't
require voter approval, become more popular.

     We favor COPs because they are less well known than other bonds, which
allows us to buy them for less than comparable, more familiar types of
securities.

WHAT DO YOU SEE AHEAD FOR INTEREST RATES AND THE MUNICIPAL MARKET?

     We're more cautious than we were a year ago, but we're still optimistic
about the municipal bond market. Inflation still appears to be under control,
and there's evidence that the U.S. economy may be slowing. Given that backdrop,
we believe the Fed will refrain from raising interest rates further for the
balance of 1999, in part to avoid upsetting global financial markets that are
already jittery about Y2K.

     As for next year, the outlook is murkier. The market could continue to
experience volatility as investors focus on each economic data release to
determine if the economy is growing at an inflationary pace or if it's slowing
down. But eventually, we think that interest rates will move down in response to
slower economic growth.

WITH THAT BACKDROP IN MIND, HOW WILL YOU POSITION THE FUND?

     We're likely to maintain our current duration position and hold discount
bonds as long as we believe that rates will eventually fall. We also plan to
continue to work closely with our credit research team to look for attractively
valued securities, such as COPs. That approach has helped contribute to our
long-term success.

Statements of Assets and Liabilities
- --------------------------------------------------------------------------------

This statement breaks down the fund's ASSETS (such as  securities, cash, and
other receivables) and LIABILITIES (money owed for securities purchased,
management fees, and other liabilities) as of the last day of the reporting
period. Subtracting the liabilities from the assets results  in the fund's NET
ASSETS. The net assets divided by shares outstanding is the share price, or NET
ASSET VALUE PER SHARE. This statement also breaks down the fund's net assets
into capital (shareholder investments) and performance (investment income and
gains/losses).

Notes to Financial Statements
- --------------------------------------------------------------------------------

AUGUST 31, 1999

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION -- American Century California Tax-Free and Municipal Funds
(the trust) is registered under the Investment Company Act of 1940 as an
open-end management investment company. California High-Yield Municipal Fund
(High-Yield) and California Insured Tax-Free Fund (Insured) (the funds) are two
of the seven funds issued by the trust. The funds are diversified under the 1940
Act. The funds seek income that is exempt from federal and California income
taxes. High-Yield seeks to provide as high a level of current income as is
consistent with its investment policies, which permit investment in lower-rated
and unrated municipal securities. Insured seeks to provide as high a level of
current income as is consistent with safety of principal through investment in
insured California municipal securities. The funds concentrate their investments
in a single state and therefore may have more exposure to credit risk related to
the state of California than a fund with a broader geographical diversification.
The following significant accounting policies are in accordance with generally
accepted accounting principles; these principles may require the use of
estimates by fund management.

    SECURITY VALUATIONS -- Portfolio securities are valued through a commercial
pricing service or at the mean of the most recent bid and asked prices. When
valuations are not readily available, securities are valued at fair value as
determined in accordance with procedures adopted by the Board of Trustees.

    SECURITY TRANSACTIONS -- Security transactions are accounted for as of the
trade date. Net realized gains and losses are determined on the identified cost
basis, which is also used for federal income tax purposes.

    INVESTMENT INCOME -- Interest income is recorded on the accrual basis and
includes accretion of discounts and amortization of premiums.

    INCOME TAX STATUS -- It is the funds' policy to distribute all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under the provisions of the Internal
Revenue Code. Accordingly, no provision has been made for federal or state
income taxes.

    DISTRIBUTIONS TO SHAREHOLDERS -- Distributions from net investment income
for the funds are declared daily and distributed monthly. Distributions from net
realized gains for the funds are declared and paid annually. For the year ended
August 31, 1999, 100% (unaudited) of the funds' distributions from net
investment income have been designated as exempt from federal and California
state income tax.

    The character of distributions made during the year from net investment
income or net realized gains may differ from their ultimate characterization for
federal income tax purposes. These differences reflect the differing character
of certain income items and net realized gains and losses for financial
statement and tax purposes and may result in reclassification among certain
capital accounts.

    FUTURES CONTRACTS -- The funds may buy and sell interest rate futures
contracts relating to debt securities. Futures transactions may be used to
maintain cash reserves while remaining fully invested, to facilitate trading, to
reduce transaction costs, or to pursue higher investment returns when a futures
contract is priced more attractively than its underlying security or index. One
of the risks of entering into futures contracts may include the possibility that
the changes in value of the contract may not correlate with the changes in value
of the underlying securities. Upon entering into a futures contract, the funds
are required to deposit either cash or securities in an amount equal to a
certain percentage of the contract value (initial margin). Subsequent payments
(variation margin) are made or received daily, in cash, by the funds. The
variation margin is equal to the daily change in the contract value and is
recorded as an unrealized gain or loss. The funds recognize a realized gain or
loss when the contract is closed or expired. Net realized and unrealized gains
or losses occurring during the holding period of futures contracts are a
component of realized gain (loss) on investments and unrealized appreciation
(depreciation) on investments, respectively. There were no open futures
contracts at August 31, 1999.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is the trust's
distributor. Certain officers of FDI are also officers of the trust.

- --------------------------------------------------------------------------------
2. TRANSACTIONS WITH RELATED PARTIES

    The trust has entered into a Management Agreement with American Century
Investment Management, Inc. (ACIM), under which ACIM provides each fund with
investment advisory and management services in exchange for a single, unified
management fee. The Agreement provides that all expenses of the funds, except
brokerage, taxes, portfolio insurance, interest, fees and expenses of the
Trustees who are not considered "interested persons" as defined in the
Investment Company Act of 1940 (including counsel fees) and extraordinary
expenses, will be paid by ACIM. The fee is calculated daily and paid monthly. It
consists of an Investment Category Fee based on the average net assets of the
funds in a specific fund's investment category and a Complex Fee based on the

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees of the American Century California Tax-Free and Municipal Funds
and Shareholders of the California High-Yield Municipal Fund and  the California
Insured Tax-Free Fund:

In our opinion, the accompanying statements of assets and liabilities, including
the schedules of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of the California High-Yield Municipal
Fund and the California Insured Tax-Free Fund (formerly the American Century -
Benham California High-Yield Municipal Fund and the American Century - Benham
California Insured Tax-Free Fund, respectively) (the "Funds") at August 31,
1999, and the results of their operations for the year then ended, the changes
in their net assets and the financial highlights for each of the two years in
the period then ended, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Funds'
management; our responsibility is to express an opinion on these financial
statements based on our audits. The financial highlights for each of the three
years in the period ended August 31, 1997, were audited by other auditors, whose
report, dated October 3, 1997, expressed an unqualified opinion on those
statements. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards, which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits, which included confirmation of securities at August
31, 1999 by correspondence with the custodian and brokers and the application of
alternative auditing procedures where confirmations from brokers were not
received, provide a reasonable basis for the opinion expressed above.

Background Information
- --------------------------------------------------------------------------------

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers 38 fixed-income funds, ranging from money market
portfolios to long-term bond funds and including both taxable and tax-exempt
funds. Each is managed to provide a "pure play" on a specific sector of the
fixed-income market.

     To ensure adherence to this principle, the basic structure of each
portfolio is tied to a specific market index. Fund managers attempt to add value
by making modest portfolio adjustments based on their analysis of prevailing
market conditions.

     Investment decisions are made by management teams, which meet regularly to
discuss market analysis and investment strategies.

     In addition to these principles, each fund has its own investment policies

     CALIFORNIA HIGH-YIELD MUNICIPAL seeks to provide a high level of interest
income exempt from both federal and California state income taxes by investing
in California municipal securities. The fund typically invests a portion of its
assets in lower-quality and unrated securities, which are subject to increased
credit risk, default risk and liquidity risk. The fund is managed to maintain an
average maturity of 10 years or more.

     CALIFORNIA INSURED TAX-FREE seeks to provide a high level of interest
income exempt from both federal and California state income taxes by investing
in insured California municipal securities. The fund is managed to maintain an
average maturity of 10 years or more. Fund shares are not insured.

COMPARATIVE INDICES

     The following index is used in the report for fund performance comparisons.
It is not an investment product available for purchase.

     THE LEHMAN BROTHERS LONG-TERM MUNICIPAL BOND INDEX is composed of more than
2,800 municipal bonds with maturities greater than 22 years. The average credit
rating of the securities in the index is AA2/AA3. The average maturity of the
index is approximately 27 years.

LIPPER RANKINGS

     LIPPER INC. is an independent mutual fund ranking service that groups funds
according to their investment objectives. Rankings are based on average annual
returns for each fund in a given category for the periods indicated. Rankings
are not included for periods less than one year.

     The Lipper categories for the California High-Yield Municipal and Insured
Tax-Free funds are:

     CALIFORNIA MUNICIPAL DEBT FUNDS (High-Yield Municipal) -- funds that invest
at least 65% of assets in securities that are exempt from taxation in
California.

     CALIFORNIA INSURED MUNICIPAL DEBT FUNDS (Insured Tax-Free) -- funds that
invest at least 65% of assets in securities that are exempt from taxation in
California and insured as to timely payment of interest and repayment of
principal.

CREDIT RATING GUIDELINES

       CREDIT RATINGS ARE ISSUED BY INDEPENDENT RESEARCH COMPANIES SUCH AS
STANDARD & POOR'S AND MOODY'S. THEY ARE BASED ON AN ISSUER'S FINANCIAL STRENGTH
AND ABILITY  TO PAY INTEREST AND PRINCIPAL IN A TIMELY MANNER.

       SECURITIES RATED AAA, AA, A, OR BBB ARE CONSIDERED "INVESTMENT-GRADE"
SECURITIES, MEANING THEY ARE RELATIVELY SAFE FROM DEFAULT. CALIFORNIA HIGH-YIELD
MUNICIPAL MAY INVEST MORE THAN 50% OF ITS PORTFOLIO IN SECURITIES THAT ARE BELOW
INVESTMENT GRADE OR NOT RATED. HERE ARE THE MOST COMMON CREDIT RATINGS AND THEIR
DEFINITIONS:

*   AAA--EXTREMELY STRONG ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   AA--VERY STRONG ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   A--STRONG ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   BBB--GOOD ABILITY TO MEET FINANCIAL OBLIGATIONS.

*   BB--LESS VULNERABLE TO DEFAULT THAN OTHER LOWER-QUALITY ISSUES BUT DO
    NOT QUITE MEET INVESTMENT-GRADE STANDARDS.

*   IT'S IMPORTANT TO NOTE THAT CREDIT RATINGS ARE SUBJECTIVE, REFLECTING THE
    OPINIONS OF THE RATING AGENCIES; THEY ARE NOT ABSOLUTE STANDARDS OF QUALITY.

Glossary
- --------------------------------------------------------------------------------

RETURNS

* TOTAL RETURN figures show the overall percentage change in the value of a
hypothetical investment in the fund and assume that all of the fund's
distributions are reinvested.

* AVERAGE ANNUAL RETURNS illustrate the annually compounded returns that would
have produced the fund's cumulative total returns if the fund's performance had
been constant over the entire period. Average annual returns smooth out
variations in a fund's return; they are not the same as fiscal year-by-year
results. For fiscal year-by-year returns, please refer to the "Financial
Highlights" on pages 25-26.

YIELDS

* 30-DAY SEC YIELD represents net investment income earned by the fund over a
30-day period, expressed as an annual percentage rate based on the fund's share
price at the end of the 30-day period. The SEC yield should be regarded as an
estimate of the fund's rate of investment income, and it may not equal the
fund's actual income distribution rate, the income paid to a shareholder's
account, or the income reported in the fund's financial statements.

* 30-DAY TAX-EQUIVALENT YIELDS show the taxable yields that investors in a
combined California and federal income tax bracket would have to earn before
taxes to equal the fund's tax-free 30-day SEC yield.

INVESTMENT TERMS

* BASIS POINT -- a basis point equals one one-hundredth of a percentage point
(or 0.01%). Therefore, 100 basis points equal one percentage point (or 1%).

* COUPON -- the stated interest rate of a security.

* YIELD CURVE -- a graphic representation of the relationship between maturity
and yield for fixed-income securities. Yield curve graphs plot lengthening
maturities along the horizontal axis and rising yields along the vertical axis.

STATISTICAL TERMINOLOGY

* NUMBER OF SECURITIES -- the number of different securities held by a fund on a
given date.

* WEIGHTED AVERAGE MATURITY (WAM) -- a measure of the sensitivity of a
fixed-income portfolio to interest rate changes. WAM indicates the average time
until the securities in the portfolio mature, weighted by dollar amount.

* AVERAGE DURATION -- another measure of the sensitivity of a fixed-income
portfolio to interest rate changes. Duration is a time-weighted average of the
interest and principal payments of the securities in a portfolio.

* EXPENSE RATIO -- the operating expenses of the fund, expressed as a percentage
of average net assets. Shareholders pay an annual fee to the investment manager
for investment advisory and management services. The expenses and fees are
deducted from fund income, not from each shareholder account. (See Note 2 in the
Notes to Financial Statements.) TYPES OF MUNICIPAL SECURITIES

* COPS (CERTIFICATES OF PARTICIPATION)/ LEASES --securities issued to finance
public property improvements (such as city halls and police stations) and
equipment purchases. Certificates of participation represent long-term debt
obligations, but leases have a higher risk profile because they require annual
appropriation.

* GO (GENERAL OBLIGATION) BONDS -- securities backed by the taxing power of the
issuer.

* LAND-SECURED BONDS -- securities such as Mello-Roos bonds and 1915 Act bonds
that are issued to finance real estate development projects.

* PREREFUNDED/ETM BONDS -- securities refinanced or escrowed to maturity by the
issuer because of their premium coupons (higher-than-market interest rates).
These bonds tend to have higher credit ratings because they are backed by
Treasury securities.

* REVENUE BONDS--securities backed by revenues from sales taxes or from a
specific project, system, or facility (such as a hospital, electric utility, or
water system).

FUND CLASSIFICATIONS

INVESTMENT OBJECTIVE

    The investment objective may be based on the fund's objective as stated in
its prospectus or fund profile, or the fund's categorization by independent
rating organizations based on its management style.

* CAPITAL PRESERVATION -- offers taxable and tax-free money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME -- offers funds that emphasize both growth and income provided
by either dividend-paying equities or a combination of equity and fixed-income
securities.

* GROWTH -- offers funds with a focus on capital appreciation and long-term
growth, generally providing high return potential with corresponding high price
fluctuation risk.

RISK

    The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds. Please be aware that the fund's category may change over
time. Therefore, it is important that you read a fund's prospectus or fund
profile carefully before investing to ensure its objectives, policies and risk
potential are consistent with your needs.

* CONSERVATIVE -- these funds generally provide lower return potential with
either low or minimal price fluctuation risk.

* MODERATE -- these funds generally provide moderate return potential with

The investment objective may be based on the fund's objective as stated in its
prospectus or fund profile, or the fund's categorization by independent rating
organizations based on its management style.

The classification of funds by risk category is based on quantitative
historical measures as well as qualitative prospective measures. It is not
intended to be a precise indicator of future risk or return levels. The degree
of risk within each category can vary significantly, and some fund returns have
historically been higher than more aggressive funds or lower than more
conservative funds. Please be aware that a fund's category may change over time.
Therefore, it is important that you read a fund's prospectus or fund profile
carefully before investing to ensure its objectives, policies and  risk
potential are consistent with your needs.For a definition of fund categories,
see the Glossary.

* While listed within the Income investment objective, the Target funds do not
  pay current dividend income. Income dividends are distributed once a year in
  December. The Target funds are listed in  all three risk categories due to the
  dramatic price volatility investors may experience during certain market
  conditions. If held to their target dates, however, they can offer a
  conservative, dependable way to invest for a specific time horizon.

Please call 1-800-345-2021 for a prospectus or profile on any American Century
fund. These documents contain important information including charges and
expenses, and you should read them carefully before you invest or send money.
