     California municipal money market yields rose during the year ended August
31, 2000. The Federal Reserve raised short-term interest rates four times to
slow the U.S. economy and keep inflation contained.

     However, strong demand for municipal money market securities kept their
yields from rising as much as the Fed's short-term rates. This was especially
true in California, where freshly minted dot-com millionaires looked to preserve
some of their newfound wealth in a tax-free investment.

     In this environment, American Century's California money market funds
continued to provide shareholders with an above-average level of tax-free income
(according to Lipper Inc., an independent mutual fund ranking service). Fund
manager Todd Pardula talks more about the funds' performance on pages 5 and 12.

     Turning to corporate matters, Chase Manhattan Corp. recently announced
plans to acquire J.P. Morgan & Co., which became a substantial minority
shareholder in American Century Companies, Inc. in 1998. If the transaction is
completed as expected, J.P. Morgan Chase, the new enterprise, will own the
shares of American Century currently held by Morgan. Corporate control of
American Century is not affected by this transaction. We will be exploring ways
to partner with J.P. Morgan Chase for the benefit of fund shareholders.

     In other corporate news, some American Century executives have assumed
important new responsibilities. For example, we chose to divide the chairman of
the board position between the two of us and named American Century President
William M. Lyons chief executive officer, giving him ultimate management
responsibility for the entire company.

     These changes, plus the promotion of some key investment professionals,
strengthen the leadership of our investment management area and allow us to
pursue other worthwhile endeavors. For example, Jim Stowers III will focus more
on product innovation (in particular, leveraging our earnings-acceleration
screening system to build the next generation of portfolio management
technologies). However, he'll continue to serve on the investment teams for the
Ultra and Veedot funds.

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

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

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

CALIFORNIA TAX-FREE MONEY MARKET

*   The fund's one-year return for the fiscal year ended August 31, 2000, ranked
    in the top quarter of the California money market funds tracked by Lipper
    Inc. (See page 4 for standardized ranking and performance information.)

*   California Tax-Free Money Market's yield was consistently higher than its
    Lipper category average throughout the fiscal year.

*   Although four interest rate hikes by the Federal Reserve pushed all money
    market yields higher, strong demand and less new issuance limited the rise
    in California municipal money market yields.

*   We bought a number of one-year notes in June when yields were relatively
    attractive, and this caused the fund's average maturity to extend
    dramatically.

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, 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?

     There is a 10-business-day holding period for deposited funds--including
your initial investment in a new account. There is a one-business-day holding
period for wire transfers.

IS THERE A COST FOR WRITING CHECKS ON MY MONEY MARKET ACCOUNT?

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

HOW CAN I KEEP TRACK OF MY MONEY MARKET FUND TRANSACTIONS BETWEEN ACCOUNT
STATEMENTS?

     You can access your investments any time through our automated telephone
line and the American Century Web site. These services provide fund yields,
returns, account information, and transaction services.

     You can keep tabs on your investments 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* weekdays,
     7 a.m.-7 p.m. Central time Saturdays, 9 a.m.-2 p.m. Central time

WHY DOES MY MONEY FUND YIELD FLUCTUATE?

     Money market funds are managed to maintain a stable $1 share price, but
their yields will fluctuate with changes in market conditions. Common reasons
for changes in your fund's yield are adjustments to Federal Reserve interest
rate policy, the outlook for inflation, and supply and demand for money market
securities.

     Keep in mind that no money market fund is guaranteed or insured by the U.S.
government. And although money market funds are intended to preserve the value
of your investment at $1 per share, there's no guarantee that they'll be able to
do so.

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.

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 to five days.

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

* We must have your written authorization on file if you wish to make exchanges
  by phone, on our Automated Information Line, or through our Web site.

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

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

HOW DID CALIFORNIA TAX-FREE MONEY MARKET PERFORM FOR THE YEAR ENDED AUGUST 31,
2000?

     The fund returned 3.11%, beating the 2.91% average return of the 52
"California Tax-Exempt Money Market Funds" tracked by Lipper Inc. The fund's
one-year return ranked in the top quarter of its Lipper category, and its
longer-term returns are similarly strong (see the previous page).

     In addition, California Tax-Free Money Market's yield was consistently
higher than its Lipper category average throughout the fiscal year.

MUNICIPAL MONEY MARKET YIELDS WENT UP IN THE PAST YEAR (THE FUND'S 7-DAY CURRENT
YIELD ROSE FROM 2.54% TO 3.39%). WHY?

     In general, short-term interest rates rose as the Federal Reserve raised
rates four times to slow the economy and fight inflation.

     However, California municipal money market yields didn't increase as much
as you might expect given the four Fed rate hikes. Supply and demand factors,
which tend to have the biggest short-term impact on municipal money market
yields, kept California yields in check.

     Demand picked up as the volatile stock market convinced many investors to
diversify into more conservative investments. Tax-free investing also appealed
to those who have been pushed into higher tax brackets by strong stock returns.

     On the supply side, issuance has been lower than in years past because
municipalities are flush with cash-- the strong economy has boosted tax revenues
and reduced borrowing needs. For example, the state of California will not issue
any short-term revenue notes this year, the first time that's happened in about
20 years.

     When there's increased demand for a declining number of money market
securities, yields tend to move lower.

GIVEN THIS ENVIRONMENT, HOW DID YOU KEEP THE FUND'S YIELD AHEAD OF THE PACK?

     Relatively low expenses helped. California Tax-Free Money Market's annual
expense ratio is 0.49%, compared with the 0.61% average expense ratio of the
Lipper category.

     We also took advantage of opportunities to boost the fund's yield. In the
first half of the fiscal year, we increased our holdings of commercial paper
when it was offering higher yields than were available on variable-rate notes,
which make up a majority of the portfolio.

     In June--a month when many California municipalities typically issue
one-year notes--we bought a number of notes with very attractive yields. This
caused the fund's average maturity to extend from around 35 days in early March,
when it was a little shorter than the average California municipal money market
fund, to 70 days by the end of June. We maintained this longer average maturity
through the end of August.

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

     An interview with Todd Pardula (pictured on page 5), a portfolio manager on
the California Tax-Free and Municipal funds investment team.

HOW DID CALIFORNIA MUNICIPAL MONEY MARKET PERFORM FOR THE YEAR ENDED AUGUST 31,
2000?

     The fund returned 3.19%, beating the 2.91% average return of the 52
"California Tax-Exempt Money Market Funds" tracked by Lipper Inc. The fund's
one-year return ranked in the top five of its Lipper category, and its
longer-term returns are similarly strong (see the previous page).

     In addition, California Municipal Money Market's yield was consistently
higher than its Lipper category average throughout the fiscal year.

MUNICIPAL MONEY MARKET YIELDS WENT UP IN THE PAST YEAR (THE FUND'S 7-DAY CURRENT
YIELD ROSE FROM 2.67% TO 3.46%). WHY?

     In general, short-term interest rates rose as the Federal Reserve raised
rates four times to slow the economy and fight inflation.

     However, California municipal money market yields didn't increase as much
as you might expect given the four Fed rate hikes. Supply and demand factors,
which tend to have the biggest short-term impact on municipal money market
yields, kept California yields in check.

     Demand picked up as the volatile stock market convinced many investors to
diversify into more conservative investments. Tax-free investing also appealed
to those who have been pushed into higher tax brackets by strong stock returns.

     On the supply side, issuance has been lower than in years past because
municipalities are flush with cash-- the strong economy has boosted tax revenues
and reduced borrowing needs. For example, the state of California will not issue
any short-term revenue notes this year, the first time that's happened in about
20 years.

     When there's increased demand for a declining number of money market
securities, yields tend to move lower.

GIVEN THIS ENVIRONMENT, HOW DID YOU KEEP THE FUND'S YIELD AHEAD OF THE PACK?

     Relatively low expenses helped. California Municipal Money Market's annual
expense ratio is 0.49%, compared with the 0.61% average expense ratio of the
Lipper category.

     Another factor in our favor was the fund's significant exposure to AMT
paper (securities subject to the federal alternative minimum tax), which tends
to offer higher yields than other municipal money market securities.

     Actually, though, the fund currently holds less AMT paper than it did six
months ago. We bought a number of non-AMT one-year notes with very attractive
yields in June, a month when many California municipalities typically issue
one-year notes.

     This caused the fund's average maturity to extend from around 30 days in
early March, when it was a little shorter than the average California municipal
money market fund, to almost 70 days by the end of June. Although we allowed the
average maturity to roll down to about 55 days by the end of August, it was
still longer than the average California municipal money market fund.

Statement 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 payables) 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, 2000

--------------------------------------------------------------------------------
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
policies 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, 2000, 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, 2000, accumulated net realized capital loss carryovers for
Tax-Free Money Market of $278,807 (expiring in 2004 through 2008) and for
Municipal Money Market of $158,356 (expiring in 2003 through 2006) may be used
to offset future taxable gains.

    Municipal Money Market has elected to treat $609 of net capital losses
incurred in the ten month period ended August 31, 2000 as having been incurred
in the following fiscal year.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the trust. 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, 2000,
the effective annual management fee for both funds was 0.49%.

    Effective March 13, 2000, American Century Investment Services, Inc. (ACIS),
became a distributor of the trust.

    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, a
distributor of the trust, ACIS, and the trust's transfer agent, American Century
Services Corporation.

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 (the "Funds") at
August 31, 2000, and the results of their operations for the year then ended,
the changes in net assets for the two years in the period then ended, and the
financial highlights for the three years in the period then ended, in conformity
with accounting principles generally accepted in the United States of America.
The financial highlights for each of the two 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. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States of America, 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, 2000 by correspondence with the custodian and brokers, provide a reasonable
basis for our opinion.

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.

     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 funds in Lipper's CALIFORNIA TAX-EXEMPT MONEY MARKET FUNDS category
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.

     A-1 (which includes A-1+) is Standard & Poor's highest credit rating for
short-term securities. Here are the most common short-term credit ratings and
their definitions:

*    A-1+: extremely strong ability to meet financial obligations.

*    A-1: strong ability to meet financial obligations.

*    A-2: satisfactory ability to meet financial obligations.

     It's important to note that credit ratings are subjective. They reflect the
opinions of the rating agencies that issue them and 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 total returns, please refer to the "Financial
Highlights" on pages 20-21.

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 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 -- municipal 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
stabilize their market values using periodic (daily or weekly) interest rate
adjustments.

FUND CLASSIFICATIONS

    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.

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.

* 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.

James E. Stowers, Jr., standing, with James E. Stowers III

     We're proud to report that our California High-Yield Municipal and
California Insured Tax-Free funds provided better-than-average returns during
the fiscal year ended August 31, 2000 (see pages 5 and 13). Municipal bonds
performed relatively well thanks to increased demand from an unlikely
source--California's newly minted dot-com millionaires, who sought to preserve
some of their newfound wealth in tax-free investments. The investment
professionals on our California municipal team review fund performance and the
12 months in more detail beginning on page 3.

     Turning to corporate matters, Chase Manhattan Corp. recently announced
plans to acquire J.P. Morgan & Co., which became a substantial minority
shareholder in American Century Companies, Inc. in 1998. If the transaction is
completed as expected, J.P. Morgan Chase, the new enterprise, will own the
shares of American Century currently held by Morgan. Corporate control of
American Century is not affected by this transaction. We will be exploring ways
to partner with J.P. Morgan Chase for the benefit of fund shareholders.

     In other corporate news, some American Century executives have assumed
important new responsibilities. For example, we chose to divide the chairman of
the board position between the two of us and named American Century President
William M. Lyons chief executive officer, giving him ultimate management
responsibility for the entire company.

     These changes, plus the promotion of some key investment professionals,
strengthen the leadership of our investment management area and allow us to
pursue other worthwhile endeavors. For example, Jim Stowers III will focus more
on product innovation (in particular, leveraging our earnings-acceleration
screening system to build the next generation of portfolio management
technologies). However, he'll continue to serve on the investment teams for the
Ultra and Veedot funds.

     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

*   The fiscal year ended August 31, 2000, saw California municipal bonds
    produce solid returns.

*   The year was a tale of two halves--interest rates rose in late 1999 and
    early 2000, limiting performance. But interest rates reversed course in
    recent months, leading to much better returns.

*   Supply and demand factors worked in favor of California bonds. A healthy
    state economy meant municipalities had less need to borrow, while California
    investors found themselves wealthier and in need of the tax advantages
    offered by municipal bonds.

CREDIT REVIEW

*   Strong and sustained economic growth helped improve California's financial
    health and the fiscal well-being of its municipalities.

*   Municipal credit rating agencies rewarded the state and certain of its
    agencies with a credit rating upgrade as a result of improved financial
    conditions.

*   The state's robust economy meant its tax- and revenue-backed bonds performed
    well.

*   About the only sector that lagged was health care. Declining receipts and
    increased costs squeezed health facilities.

CALIFORNIA HIGH-YIELD MUNICIPAL

*   Below-average expenses and an above-average yield helped this fund
    outperform the median return of its Lipper peer group (see page 5).

*   Valuable input from our credit research team steered the fund away from
    bonds that experienced downgrades, and supported the decision to underweight
    health care bonds, a troubled sector.

*   Swapping out of lower-coupon bonds and adding insured bonds also boosted
    fund performance.

*   A resilient state economy and favorable supply and demand fundamentals
    should provide support for California high-yield bonds through the end of
    the year.

CALIFORNIA INSURED TAX-FREE

*   The portfolio performed well, producing better returns and more state and
    federal tax-free income than the average of the funds in its Lipper group
    (see page 13).

*   The two biggest reasons for our outperformance were our below-average
    expenses and the way we structured the coupons of the bonds in the
    portfolio.

*   Municipal bond insurers remained in outstanding financial condition, which
    was key to maintaining the high credit quality of the fund.

*   We're generally positive on municipal bonds going forward. We think the
    Federal Reserve has successfully slowed the economy and kept inflation in
    check.

Market Perspective from Randall W. Merk

MUNICIPAL BONDS REBOUND

     After suffering disappointing returns during the last four months of 1999
and the first month of 2000, municipal bonds rallied, particularly from mid-May
through the end of August 2000. As a result, California municipal bond returns
finished near long-term historical averages in the fiscal year ended August 31,
2000.

     The fiscal year for our California municipal funds began during a period
when the markets were concerned with strong economic growth and the possibility
of higher inflation. The Federal Reserve raised short-term interest rates in
November for the third time in five months to rein in the economy.

     Even though the Fed continued to raise rates through May 2000, municipal
bond prices began rising in May in anticipation that the Fed might end its
rate-raising campaign. Some economic reports indicated that pockets of the
economy were beginning to slow and inflationary pressures were fading.

LESS SUPPLY, MORE DEMAND

     The municipal market's rebound was aided by favorable supply and demand. On
the supply side, refinancing of old debt was subdued as interest rates rose,
diminishing the financial rewards for refinancing. Furthermore, many issuers had
already reached the legal limit on the number of times they were allowed to
refinance. Finally, the strong economy bolstered the financial stability of many
municipal issuers, reducing their borrowing needs.

     On the demand side, stock market volatility prompted many newly affluent
individuals in high tax brackets to rebalance their portfolios and buy municipal
bonds. The highest tax-equivalent yields in years also attracted investors. For
an investor in the highest combined federal and California tax bracket, a
30-year AAA-rated California municipal bond offered a tax-equivalent yield of
over 10% last spring.

HIGH-YIELD BONDS LAG

     Lower-rated and non-rated bonds, which make up the high-yield sector,
lagged investment-grade municipal bonds (those rated BBB or higher). High-yield
bonds, which suffered from heavy tax-loss selling in late 1999 and early 2000,
rallied with the rest of the municipal market during the second and third
quarters of 2000, but continued to lag investment-grade bonds. That's because
high-yield bonds are less sensitive to interest rate changes (their durations
are lower) due to their higher interest coupons. As a result, high-yield bond
prices typically decline less than those of investment-grade bonds when rates
rise but gain less when rates fall, as they did at the end of the period.

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

     An expanding economy bolstered California's municipal credit strength
during the year ended August 31, 2000. The state continued to outpace the nation
as whole in terms of personal income gains, employment growth, and overall
economic activity.

SECTOR ANALYSIS

     Tax-backed bonds were among the primary beneficiaries of California's
ongoing economic strength. Brisk consumer spending lifted sales taxes, while
robust real estate activity boosted property tax collections. Income tax
collections also rose substantially as income levels climbed and key employment
measures grew faster than the national average. Furthermore, the state enjoyed
dramatic revenue growth from increased capital gains tax collections.

     Credit trends were also favorable among bonds backed by revenue from
specific municipal projects or entities. The healthy economy helped maintain
strong revenue trends for the water and sewer, transportation, and housing
sectors. Even public power companies enjoyed better conditions. Higher rates and
increased customer usage offset the pressures of increased competition for
utilities.

     About the only weak sector was health care. Reduced federal spending on
Medicare and other programs mandated by the Balanced Budget Act of 1997
continued to affect the revenues of health care facilities. The strict vigilance
of cost-conscious health insurers (particularly HMOs), combined with higher drug
and wage expenses, also squeezed the earnings of health facilities.
Worse-than-expected operating results caused several downgrades of health care
entities.

CALIFORNIA IS UPGRADED

     In recognition of California's robust economy and its "increased fiscal
conservatism," two major municipal bond rating agencies recently upgraded the
credit rating of the state and some of its issuing agencies. California also was
applauded for increasing its cash and budget reserves to record levels and for
matching expenditures with cash inflows. With the new, higher credit rating, the
state's borrowing costs should be reduced, further boosting California's fiscal
health.

THE INTERNET AND SALES TAXES

     The rise of Internet sales--which are not taxed by municipal issuers--has
raised questions about lost tax receipts and their impact on municipal bond
credit quality. While we are watching developments closely--including recent
efforts by legislators to levy Internet sales taxes--our view is that even if
e-commerce spending increases 10-fold over the next few years, it will represent
only about 10% of total retail transactions. At that level, we don't believe
e-commerce represents a major threat to the tax bases of most states and
municipalities, including California.

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

     An interview with Steven Permut, a portfolio manager on the California
High-Yield Municipal fund investment team.

HOW DID CALIFORNIA HIGH-YIELD MUNICIPAL PERFORM DURING THE YEAR ENDED AUGUST 31,
2000?

     The fund continued to outpace its peers, returning 6.70% compared with the
6.47% average total return of the 109 "California Municipal Debt Funds" tracked
by Lipper Inc.

     The fund's below-average expenses and higher yield aided this
outperformance. For the year ended August 31, 2000, the fund's expense ratio was
0.54%, compared with the 1.07% average for its Lipper group. All else being
equal, lower expenses mean higher yields and returns. The fund's 30-day SEC
yield as of August 31, 2000, was 5.26%, compared with the 4.34% average yield of
the Lipper peer group.

WHAT OTHER FACTORS HELPED THE FUND OUTPACE ITS PEER GROUP AVERAGE DURING THE
PAST 12 MONTHS?

     While the past year generally produced stable or improving credit
conditions for most municipal issuers, it also had its share of defaults and
downgrades. However, our credit team's extensive research and comprehensive
surveillance successfully steered us away from bonds that experienced downgrades
and devaluation.

     The team's analysis also prompted us to underweight health care bonds,
which performed poorly. Health care facilities continued to face a host of
challenges that have become all too familiar. Among those hurdles were
reimbursement cutbacks, intensifying competition, and financial shortfalls for
some high-profile hospitals across the nation. The punishment was fairly
indiscriminate--even bonds issued by well-managed, financially-sound health care
organizations declined in value.

     In choosing health care bonds for the fund, we emphasized providers that
are less dependent on federal payments, are led by strong management teams, and
have a proven track record of good financial results. We also look for providers
located in service areas with little or no competition.

WHAT CHANGES DID YOU MAKE TO THE PORTFOLIO DURING THE YEAR?

     We continued to swap bonds issued when interest rates and bond coupons were
lower for comparable bonds with coupons at current interest rates. For example,
we sold some bonds with coupons in the 5% range and replaced them with bonds in
the 6% to 7% range.

     One area that presented us with attractive opportunities to make these
exchanges was land-secured bonds, which typically are used to finance real
estate development. Demand for housing across California remained strong and, in
some pockets, dramatically outstripped available supply.

California High-Yield Municipal--Q&A
--------------------------------------------------------------------------------
                                                                    (Continued)

INTERESTINGLY, YOU ALSO ADDED AAA INSURED BONDS. WHAT ROLE DID THEY PLAY?

     At the end of August 2000, about 22% of the fund was invested in insured
bonds. Insured bonds (bonds that are insured as to timely payment of interest
and repayment of principal) served two important functions for us.

     First, with municipal yields falling since mid-May, we wanted more interest
rate sensitivity. Insured bonds are much more sensitive to interest rate changes
than non-rated bonds. Our expanded insured holdings helped the fund participate
more fully in the recent municipal bond market rally.

     Second, insured bonds tend to be more liquid, or easily traded, than
non-rated bonds. The insureds provided us with more flexibility to buy and sell
as we saw market opportunities arise.

SO YOU ADDED INSURED BONDS INSTEAD OF CHANGING THE FUND'S DURATION (A MEASURE OF
INTEREST RATE SENSITIVITY) SIGNIFICANTLY?

     That's basically correct. We tend to avoid making large duration bets on
the direction of interest rates. In keeping with our investment approach, we
kept our duration within 10% of that of the fund's peer group.

WHAT'S YOUR OUTLOOK FOR THE CALIFORNIA HIGH-YIELD MUNICIPAL MARKET?

     The supply/demand environment improved significantly during the summer, a
trend that we think is likely to continue through year end. Given the relatively
high interest rates issuers currently have to reckon with, even after the recent
rally, we think they will hold off on issuing a lot of new bonds.

     At the same time, demand has begun to firm in response to recent volatility
among technology stocks. To the extent that the nervousness over stocks
continues and investors continue to seek out the high levels of tax-free income
that high-yield municipals currently offer, the California high-yield municipal
bond market could benefit. For an investor in the highest combined federal and
California tax bracket, a 30-year high-yield California municipal bond yielding
8% offers a tax-equivalent yield of almost 15%.

     Another reason for optimism is that the underlying economic and financial
fundamentals of the bonds we hold remain strong. We think that trend will remain
in place unless the economy slows dramatically over the near term. Given the
demonstrated strength of the U.S. economy, we don't believe that's likely to
happen.

WITH THAT BACKDROP IN MIND, WHAT ARE YOUR PLANS FOR THE FUND?

     We plan to keep California High-Yield Municipal's duration neutral, rather
than making a bet on the direction of interest rates. Instead, we'll focus
primarily on the strategy that has led to our long-term success--adding
long-term value through our security selection process and our ongoing credit
analysis, while at the same time providing very competitive levels of federal
and state tax-free income.

     As always, our credit research team will thoroughly analyze our choices to
ensure that we pick bonds with a compelling balance of good long-term credit
fundamentals and appealing yields, and will continue to evaluate those
selections regularly to make sure their financial strength holds up.

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

     An interview with Dave MacEwen, a portfolio manager on the California
Insured Tax-Free fund investment team.

HOW DID CALIFORNIA INSURED TAX-FREE PERFORM DURING THE YEAR ENDED AUGUST 31,
2000?

     The fund returned 7.90%, beating the 6.99% average return of 23 "California
Insured Municipal Debt Funds" tracked by Lipper Inc.

     California Insured Tax-Free's longer-term returns also compared favorably.
For the three- and five-year periods ended August 31, 2000, the fund ranked in
the top 18% of its peer group (see the previous page for more performance
comparisons).

HOW DID THE FUND'S EXPENSES AND YIELDS COMPARE?

     On August 31, 2000, the fund had an annualized expense ratio of 0.51%.
That's less than half the 1.22% average expense ratio for the Lipper category.
As a result, California Insured Tax-Free produced more state and federal
tax-free income than the peer group average. As of August 31, the portfolio had
a 30-day SEC yield of 4.50%, while the average California insured fund yielded
4.15%, according to Lipper. The fund's yield translated to an 8.21%
tax-equivalent yield for California investors in the highest combined state and
federal tax bracket.

HOW DID THE FUND BEAT ITS PEER GROUP AVERAGES?

     A key factor in the fund's outperformance was its below-average expenses.
All else being equal, lower expenses mean higher yields and returns.

     Our "coupon barbell" strategy also boosted performance. We positioned the
fund with larger-than-average weightings in premium and discount bonds. Premiums
trade above par (face value) and carry interest payments above prevailing market
rates. Discount bonds trade below par and carry interest payments below
prevailing market rates.

     We favored premium bonds because they raised the fund's yield. The discount
bond side of the barbell resulted from when we bought discounts in early 1999.
At the time, we expected falling interest rates in response to global economic
weakness. We believed that the discount bonds would provide "call protection" if
interest rates fell and calls (bond redemptions by issuers before maturity)
became prevalent. This call protection effectively lengthened the duration
(heightened the interest rate sensitivity) of the portfolio last year.

     The increasingly long duration of our discount bond holdings detracted from
performance when interest rates and bond yields rose. Even so, we were reluctant
to sell our discount bonds at distressed prices and abandon a strategy we
believed would ultimately benefit the fund.

HOW DID YOU DECIDE TO PURSUE THAT STRATEGY?

     In selecting strategies, we typically start with a scenario analysis that
tells us how a given type of bond might perform in various market environments.
After that, we determine which bonds would give us the best risk-adjusted
returns based on our view of future market conditions.

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

WAS THE ONSET OF SPRING KINDER TO THE COUPON BARBELL POSITIONING?

     Yes. The duration of par bonds began to extend dramatically (their interest
rate sensitivity increased) as interest rates climbed. Meanwhile, the duration
of discount bonds--which had already extended in earlier months--remained
relatively stable. At the same time, the duration of premium bonds extended less
than par bonds. As a result, both discounts and premiums outpaced par bonds and
helped the fund outperform its peers.

     The market's recent rally also favored our coupon barbell strategy. During
the rally, bond yields declined and par bonds started "trading to their call
date"--meaning their prices reflected the likelihood that their issuers would
redeem them at the first possible call date. That essentially limited par bonds'
gains. In contrast, longer-duration discount bonds continued to rally.

WHAT'S THE FINANCIAL STATUS OF THE MUNICIPAL BOND INSURERS WHO INSURE THE FUND'S
BONDS?

     They're in great shape. The major insurers have AAA credit ratings, thanks
to a wealth of business activity and good overall operating results in 1999. The
demand for municipal bond insurance has declined in 2000 as debt issuance has
dropped in response to rising interest rates, but the insurers have identified
other areas of the bond market--such as asset-backed and international
securities--that are expected to drive future bond insurance growth.

WHAT'S YOUR OUTLOOK FOR INTEREST RATES  AND BONDS?

     We're reasonably optimistic that the Federal Reserve's six interest rate
hikes during the last year or so will have the intended effect of slowing the
economy and keeping inflation under wraps. Rising interest rates around the
world also reinforce this view. Increasing worker productivity is another factor
to be reckoned with. Even the Fed has begun to support the view that, thanks to
productivity gains, the economy can enjoy good growth without inflation
spiraling out of control. Higher oil prices, a weak euro, lower corporate
earnings projections, a wavering stock market, and the presidential election
also make another rate hike increasingly unlikely.

     Municipal supply and demand also offer reasons for optimism. Given
municipal issuers' reduced debt issuance needs and the refinancing deterrent
caused by higher interest rates earlier this year, we expect the supply of
municipals to remain relatively low. If demand remains strong, municipal bond
prices should rise.

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

     We're likely to keep the fund's duration slightly longer than that of its
peers while our long-term outlook for interest rates remains favorable. As
always, we'll continue to adhere to our preference for bonds that offer good
value since that's the philosophy that's helped lead to our long-term success.

Statement 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 payables) 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, 2000

--------------------------------------------------------------------------------
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 (the 1940
Act) 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 policies 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.

     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, 2000, High-Yield and Insured had accumulated net realized
capital loss carryovers for federal income tax purposes of $5,122,430 (expiring
2008) and $476,531 (expiring 2008), respectively, which may be used to offset
future taxable gains.

     High-Yield and Insured have elected to treat $6,426,841 and $1,326,227,
respectively, of net capital losses incurred in the ten month period ended
August 31, 2000, as having been incurred in the following fiscal year.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the trust. 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 1940 Act
(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 0.1925% to
0.3100% and 0.1625% to 0.2800%, for High-Yield and Insured, respectively. The
rates for the Complex Fee range from 0.2900% to 0.3100%. For the year ended
August 31, 2000, the effective annual management fee was 0.54% and 0.51% for
High-Yield and Insured, respectively.

    Effective March 13, 2000, American Century Services, Inc. (ACIS), became a
distributor of the trust.

    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, a
distributor of the trust, ACIS, and the trust's transfer agent, American Century
Services Corporation.

3.  INVESTMENT TRANSACTIONS

    Purchases of investment securities, excluding short-term investments, for
High-Yield and Insured totaled $155,408,761 and $39,763,963, respectively. Sales
of investment securities, excluding short-term investments, for High-Yield and
Insured totaled $178,363,713 and $57,277,428, respectively.

    As of August 31, 2000, accumulated net unrealized appreciation for
High-Yield and Insured was $9,918,435 and $7,625,573, respectively, which
consisted of unrealized appreciation of $12,303,416 and $9,446,700,
respectively, and unrealized depreciation of $2,384,981 and $1,821,127,
respectively. The aggregate cost of investments for federal income tax purposes
was the same as the cost for financial reporting purposes.

--------------------------------------------------------------------------------
4.  BANK LOANS

    The funds, along with certain other funds managed by ACIM, entered into an
unsecured $620,000,000 bank line of credit agreement with Chase Manhattan Bank.
The funds may borrow money for temporary or emergency purposes to fund
shareholder redemptions. Borrowings under the agreement bear interest at the
Federal Funds rate plus 0.50%. The funds did not borrow from the line during the
period ended August 31, 2000.

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 (the "Funds") at August 31, 2000,
and the results of their operations for the year then ended, the changes in net
assets for the two years in the period then ended, and the financial highlights
for the three years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America. The financial
highlights for each of the two 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. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with auditing standards
generally accepted in the United States of America, 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, 2000 by correspondence with the custodian and brokers, provide a reasonable
basis for our opinion.

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 total returns, please refer to the "Financial
Highlights" on pages 24-25.

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

    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.

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.

* 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.

[photo of James E. Stowers, Jr. and James E. Stowers III]
James E. Stowers, Jr., standing, with James E. Stowers III

     We're proud to report that our California Limited-, Intermediate-, and
Long-Term Tax-Free funds provided better-than-average returns in the fiscal year
ended August 31, 2000 (see pages 5, 11, and 19). Municipal bonds performed
relatively well thanks to an upsurge in demand from an unlikely
source--California's newly minted dot-com millionaires, who were seeking to
preserve some of their newfound wealth in a tax-free investment. Our investment
professionals review fund performance and the period in more detail beginning on
page 3.

     Turning to corporate matters, Chase Manhattan Corp. recently announced
plans to acquire J.P. Morgan & Co., which became a substantial minority
shareholder in American Century Companies, Inc. in 1998. If the transaction is
completed as expected, J.P. Morgan Chase, the new enterprise, will own the
shares of American Century currently held by Morgan. Corporate control of
American Century is not affected by this transaction. We will be exploring ways
to partner with J.P. Morgan Chase for the benefit of fund shareholders.

     In other corporate news, some American Century executives have assumed
important new responsibilities. For example, we chose to divide the chairman of
the board position between the two of us and named American Century President
William M. Lyons chief executive officer, giving him ultimate management
responsibility for the entire company.

     These changes, plus the promotion of some key investment professionals,
strengthen the leadership of our investment management area and allow us to
pursue other worthwhile endeavors. For example, Jim Stowers III will focus more
on product innovation (in particular, leveraging our earnings-acceleration
screening system to build the next generation of portfolio management
technologies). However, he'll continue to serve on the investment teams for the
Ultra and Veedot funds.

     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

*   The fiscal year ended August 31, 2000, saw California municipal bonds
    produce solid returns.

*   The year was a tale of two halves--interest rates rose in late 1999 and
    early 2000, limiting bond performance. But interest rates reversed course in
    recent months, leading to much better returns.

*   Supply and demand factors worked in favor of California bonds. A healthy
    state economy meant municipalities had less need to borrow, while California
    investors found themselves wealthier and in need of the tax advantages
    offered by municipal bonds.

CREDIT REVIEW

*   Rapid economic growth helped improve the financial health and well-being of
    California's municipalities.

*   Municipal credit rating agencies rewarded the state and certain of its
    agencies with a credit rating upgrade as a result of improved economic
    fundamentals.

*   The state's robust economy meant its tax-backed and revenue-backed bonds
    performed well.

CALIFORNIA LIMITED-TERM TAX-FREE

*   California Limited-Term Tax-Free was the top-performing fund in its Lipper
    category for the year (see page 5).

*   The portfolio performed so well relative to its Lipper group because of our
    lower-than-average expenses and because we made good calls on the fund's
    duration and maturity structure.

*   Our maturity structure also allowed us to increase the fund's yield, as did
    our decision to add select BBB bonds.

*   We think the outlook for the economy and interest rates is positive, but we
    wouldn't be surprised if short-term municipal bonds took a bit of a breather
    after performing so well in recent months.

CALIFORNIA INTERMEDIATE-TERM TAX-FREE

*   The portfolio performed very well, ranking in the top quarter of its Lipper
    group for the year (see page 11).

*   We enhanced performance by carefully managing the fund's duration, as well
    as its coupon and maturity structures.

*   Many of the changes we made to the portfolio were designed to add return as
    interest rates declined.

*   We like the outlook for municipal bonds. We think the Federal Reserve has
    done a good job on the economy and interest rates, while supply and demand
    also look to be positives.

CALIFORNIA LONG-TERM TAX-FREE

*   The portfolio performed well, producing better returns and more state and
    federal tax-free income than the average of the funds in its Lipper group
    (see page 19).

*   The two biggest reasons for our outperformance were our below-average
    expenses and the way we structured the coupons of the bonds in the
    portfolio.

*   We're generally positive on long-term municipal bonds going forward. We
    think the Federal Reserve has successfully slowed the economy and kept
    inflation in check.

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

Randall W. Merk, chief investment officer of fixed income at American Century

MUNICIPAL BONDS REBOUND

     After suffering disappointing returns during the last four months of 1999
and the first month of 2000, municipal bonds rallied, particularly from mid-May
through the end of August 2000. As a result, California municipal bond returns
finished near long-term historical averages in the fiscal year ended August 31,
2000.

     The fiscal year for our California municipal funds began during a period
when the markets were concerned with strong economic growth and the possibility
of higher inflation. The Federal Reserve raised short-term interest rates in
November for the third time in five months to rein in the economy.

     Even though the Fed continued to raise rates through May 2000, municipal
bond prices began rising in May in anticipation that the Fed might end its
rate-raising campaign. Some economic reports indicated that pockets of the
economy were beginning to slow and inflationary pressures were fading.

LESS SUPPLY, MORE DEMAND

     The municipal market's rebound was aided by favorable supply and demand. On
the supply side, refinancing of old debt was subdued as interest rates rose,
diminishing the financial rewards for refinancing. Furthermore, many issuers had
already reached the legal limit on the number of times they were allowed to
refinance. Finally, the strong economy bolstered the financial stability of many
municipal issuers, reducing their borrowing needs.

     On the demand side, stock market volatility prompted many newly affluent
individuals in high tax brackets to rebalance their portfolios and buy municipal
bonds. The highest tax-equivalent yields in years also attracted investors. For
an investor in the highest combined federal and California tax bracket, a
30-year AAA-rated California municipal bond offered a tax-equivalent yield of
over 10% last spring.

HIGH-YIELD BONDS LAG

     Lower-rated and non-rated bonds, which make up the high-yield sector,
lagged investment-grade municipal bonds (those rated BBB or higher). High-yield
bonds, which suffered from heavy tax-loss selling in late 1999 and early 2000,
rallied with the rest of the municipal market during the second and third
quarters of 2000, but continued to lag investment-grade bonds. That's because
high-yield bonds are less sensitive to interest rate changes (their durations
are lower) due to their higher interest coupons. As a result, high-yield bond
prices typically decline less than those of investment-grade bonds when rates
rise but gain less when rates fall, as they did at the end of the period.

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

     An expanding economy bolstered California's municipal credit strength
during the year ended August 31, 2000. The state continued to outpace the nation
as whole in terms of personal income gains, employment growth, and overall
economic activity.

SECTOR ANALYSIS

     Tax-backed bonds were among the primary beneficiaries of California's
ongoing economic strength. Brisk consumer spending lifted sales taxes, while
robust real estate activity boosted property tax collections. Income tax
collections also rose substantially as income levels climbed and key employment
measures grew faster than the national average. Furthermore, the state enjoyed
dramatic revenue growth from increased capital gains tax collections.

     Credit trends were also favorable among bonds backed by revenue from
specific municipal projects or entities. The healthy economy helped maintain
strong revenue trends for the water and sewer, transportation, and housing
sectors. Even public power companies enjoyed better conditions. Higher rates and
increased customer usage offset the pressures of increased competition for
utilities.

     About the only weak sector was health care. Reduced federal spending on
Medicare and other programs mandated by the Balanced Budget Act of 1997
continued to affect the revenues of health care facilities. The strict vigilance
of cost-conscious health insurers (particularly HMOs), combined with higher drug
and wage expenses, also squeezed the earnings of health facilities.
Worse-than-expected operating results caused several downgrades of health care
entities.

CALIFORNIA IS UPGRADED

     In recognition of California's robust economy and its "increased fiscal
conservatism," two major municipal bond rating agencies recently upgraded the
credit rating of the state and some of its issuing agencies. California also was
applauded for increasing its cash and budget reserves to record levels and for
matching expenditures with cash inflows. With the new, higher credit rating, the
state's borrowing costs should be reduced, further boosting California's fiscal
health.

THE INTERNET AND SALES TAXES

     The rise of Internet sales--which are not taxed by municipal issuers--has
raised questions about lost tax receipts and their impact on municipal bond
credit quality. While we are watching developments closely--including recent
efforts by legislators to levy Internet sales taxes--our view is that even if
e-commerce spending increases 10-fold over the next few years, it will represent
only about 10% of total retail transactions. At that level, we don't believe
e-commerce represents a major threat to the tax bases of most states and
municipalities, including California.

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

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

HOW DID CALIFORNIA LIMITED-TERM TAX-FREE PERFORM DURING THE YEAR ENDED AUGUST
31, 2000?

     The fund returned 5.44%, well ahead of the 4.19% average return of the 13
"California Short-Intermediate Municipal Debt Funds" tracked by Lipper Inc. The
fund's one-year performance ranked #1 in its Lipper category, and its
longer-term returns are also very strong (see the previous page).

WHY DID THE FUND PERFORM SO WELL?

     Expenses were one factor--California Limited-Term Tax-Free's expense ratio
is significantly lower than the average expense ratio of the Lipper category.
That gives the fund a head start on the rest of the group.

     We also made some timely investment decisions that worked in our favor. We
had the good fortune of being in the right places at the right times.

CAN YOU GIVE AN EXAMPLE OF YOUR  "GOOD FORTUNE?"

     The most important thing was our duration positioning. Duration measures
the fund's share-price volatility as interest rates change. A shorter duration
means less price volatility; a longer duration means greater price fluctuations.

     For the California Limited-Term Tax-Free fund, we usually keep duration in
a range between 2.75 and 3.25 years, with a "neutral" position being about three
years. This means the fund's duration is usually close to the average duration
of its Lipper category.

     In the second half of 1999, we kept duration toward the lower end of its
range, which helped limit price declines as municipal yields rose. In 2000, we
shifted gears and extended duration out to the upper end of the range. That gave
us some nice price gains as yields came down significantly.

WHY HAVE MUNICIPAL BOND YIELDS FALLEN SO MUCH THIS YEAR?

     Demand for municipal bonds has picked up significantly in the past year.
Many investors have accumulated a great deal of wealth in the stock market, but
now they're looking to protect some of their gains by shifting into a more
conservative investment, like bonds. And the tax-free status of municipal bonds
has been a big draw for "Internet millionaires" and others who have moved into
the upper tax brackets.

     At the same time, new issuance has been less than in years past because
municipalities are flush with cash-- the strong economy has boosted tax revenues
and reduced borrowing needs. When there's a lot of demand for a declining number
of bonds, yields tend to move lower.

     This effect has been especially dramatic in California, where short- and
intermediate-term bond yields are 30-40 basis points (0.30%-0.40%) below yields
in the rest of the country. Ordinarily, California yields are more like 5-10
basis points lower.

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

     It's also made for a fairly flat California yield curve (see page 3). The
gap between the yields of one-year municipal bonds and six-year bonds is about
20 basis points, compared with almost 60 basis points six months ago.

DID YOU MAKE ANY ADJUSTMENTS TO CALIFORNIA LIMITED-TERM TAX-FREE'S PORTFOLIO
BASED ON THIS ENVIRONMENT?

     We shifted to more of a "barbell" maturity position in June in anticipation
of a flattening yield curve. A barbell is heavy on the ends and light in the
middle, so a barbell position in the portfolio is heavy in shorter- and
longer-term bonds and light in intermediate-term bonds.

     We sold a number of our four- and five-year municipal bonds and split the
proceeds between 15-month notes--which were yielding about the same as the
five-year bonds at the time--and bonds maturing in 8-9 years. The fund got a big
pick-up in yield from the longer-term bonds, and the short-term notes kept the
fund's duration steady.

     Best of all, yields in the eight- to 10-year area fell faster than other
maturities, so we earned more price gains than we would have gotten if we'd
stayed with five-year bonds.

YOU NEARLY DOUBLED YOUR HOLDINGS OF  BBB-RATED BONDS IN THE PAST YEAR (FROM 7%
TO 13% OF THE PORTFOLIO). WHAT'S THE ATTRACTION?

     It was another way to add yield to the portfolio. The yield difference
between AAA bonds and bonds rated AA and A has narrowed, but you can still pick
up quite a bit of extra yield on BBB bonds.

     For example, we recently bought some BBB hospital bonds. Hospital bonds
have been under pressure for the past couple of years, and it pays to be
selective in this area of the market. But our credit research team has very high
standards, so the bonds we've added are solid from a credit standpoint, and they
have yields that are more than 100 basis points (1%) higher than AAA bonds.

LOOKING AHEAD, WHAT ARE YOUR PLANS FOR CALIFORNIA LIMITED-TERM TAX-FREE?

     We're in the process of shortening the fund's duration back to a neutral
position. A fair amount of new supply is being issued in California this fall,
which should push yields a little higher. In addition, shorter-term municipal
bonds have performed very well in the last six months and now look relatively
expensive compared with other bonds, such as corporate and government agency
securities.

     Longer term, though, we think interest rates are likely to trend lower.
After six short-term interest rate hikes since the middle of last year, the
Federal Reserve appears to be on hold. We also expect the rising price of oil,
which recently hit a 10-year high, to crimp consumer and business spending,
which in turn should slow economic growth both here and abroad.

     With that scenario in mind, we'll look to extend the fund's duration back
out to the upper end of its range later this year.

California Intermediate-Term Tax-Free--Q&A
--------------------------------------------------------------------------------
[photo of Robert Miller]

     An interview with Robert Miller, a portfolio manager on the California
Tax-Free and Municipal funds investment team. Robert--who has 12 years
experience in municipal finance, including 10 years as a credit
analyst--replaced Colleen Denzler, who was promoted to take on greater
management responsibilities.

HOW DID CALIFORNIA INTERMEDIATE-TERM TAX-FREE PERFORM IN THE FISCAL YEAR ENDED
AUGUST 31, 2000?

     The portfolio performed well, returning 6.95% and ranking in the top
quartile of the 29 "California Intermediate Municipal Debt Funds" tracked by
Lipper Inc. California Intermediate-Term Tax-Free's returns also compared
favorably with those of the Lipper group for the three-, five-, and 10-year time
horizons (see the previous page).

WHAT WERE THE KEYS TO THE FUND'S OUTPERFORMANCE?

     One key factor was that our expenses were lower than average, which gave us
a leg up on the competition. In addition, we enhanced performance by actively
managing the portfolio's duration and maturity structure to capitalize on supply
and demand imbalances in the market. Lastly, our value-oriented approach to
security selection meant we were able to purchase high-quality, uninsured bonds
that enhanced the fund's yield.

CAN YOU TELL US A LITTLE MORE ABOUT DURATION AND HOW YOU MANAGED IT?

     Duration measures the price sensitivity of a bond or bond fund to changes
in interest rates. The longer the duration, the more a bond or fund's price
fluctuates when rates change. So ideally, you want a longer duration when rates
fall and a shorter duration when rates rise.

     Earlier in 2000, we managed our duration conservatively in anticipation of
rising rates. But as rates rose, we began to see more attractive values and
better return potential in bonds with longer maturities. In addition, the summer
months typically see fairly tight supply, which often leads to higher prices on
California bonds. As a result, we began extending the portfolio's duration in
March. Having a longer duration helped returns in recent months, when interest
rates fell and California municipal bond prices rose.

WHAT TYPES OF BONDS DID YOU BUY TO EXTEND DURATION?

     We purchased both 20-year non-callable zero-coupon bonds and discount bonds
(securities that trade below par and have interest coupons below prevailing
market rates). These bonds tend to have better performance characteristics in a
declining interest rate environment. That's because zero-coupon bonds tend to
have longer durations, while non-callable and discount bonds give us "call
protection."

     Call protection is important because many municipal bonds can be "called,"
or paid off by the issuer before their maturity date. That means that when
market rates fall below a bond's coupon rate, the bond trades to its call date,
effectively shortening its duration. So having this call protection helped us
maintain a longer duration as rates declined.

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

     But the flip side to this strategy is that zeros can have a very large
impact on duration, while discount bonds lose their attractive characteristics
as their coupons get closer to the prevailing interest rate. Consequently, we
limited our purchase of zeros and sold our discount bonds as they approached
par. We used the proceeds from these sales to buy securities with better yield
and performance characteristics and to adjust the fund's maturity structure.

HOW DID YOU STRUCTURE THE PORTFOLIO?

     Early in the period, we used a bullet maturity structure, clustering the
maturities of the bonds in the portfolio between seven and 12 years. That
benefited the fund as rates rose through about mid-May because bonds with
maturities in this part of the curve held their value better than longer-term
securities.

     But in the last several months, we moved to a barbell structure, or one
that's light in bonds with maturities from seven to 12 years and heavy in
securities with three- and 20-year maturities. The longer-term discount bonds
enhanced returns as rates declined, while our shorter-term premium securities
(bonds with coupons above the prevailing rate) helped us balance out our
duration and increase our tax-free income distribution to shareholders.

YOU ALSO MENTIONED YOUR VALUE-ORIENTED APPROACH TO MANAGING THE FUND. CAN  YOU
GIVE US AN EXAMPLE OF A VALUE PLAY YOU MADE?

     Sure. We use a team-oriented management approach--portfolio managers work
hand-in-hand with our municipal credit analysts to try to find what we think are
the best values in the market. A good example of how our credit and management
teams work together is our approach to health care bonds. We generally avoided
hospital and other health care bonds in recent years--the financial health of
these institutions was damaged as they struggled to deal with industry reforms.

     But in recent months, we began to see what we believe are compelling values
in a handful of select health care issues. As a result, we've taken a modest
position in health care bonds, carefully picking over this beaten-up sector to
selectively add yield and find what we think are some very good values.

WHAT'S YOUR OUTLOOK FOR THE CALIFORNIA MUNICIPAL MARKET?

     We're generally optimistic about the market. First, we've begun to see
signs that economic growth is moderating, so it's possible the Fed's work on
interest rates is done for the rest of the year. Second, supply and demand
trends should continue to be positive for California bonds.

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

     Our strategy going forward will be to continue to look for opportunities to
enhance returns by actively managing the fund's duration and maturity structure.
In addition, we'll continue to work with our experienced credit research team to
look for value in high-quality, uninsured bonds.

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 THE YEAR ENDED AUGUST 31,
2000?

     California Long-Term Tax-Free returned 7.79%, beating the 6.47% average
return of the 109 "California Municipal Debt Funds" tracked by Lipper Inc.

     The fund's longer-term results were also better than most of its peers. For
the three-, five-, and 10-year periods ended August 31, 2000, the fund ranked in
at least the top 26% of its peer group (see the previous page for more fund
performance comparisons).

     Additionally, California Long-Term Tax-Free produced more federal and state
tax-free income than its peers. The fund's 30-day SEC yield as of August 31,
2000, was 4.66%, compared with the 4.34% average of the Lipper category. The
fund's yield translates into a tax-equivalent yield of 8.51% for investors in
the highest combined state and federal income tax bracket (see the table at
left).

WHY DID THE FUND BEAT ITS PEER AVERAGES DURING THE PAST YEAR?

     A key factor in the fund's outperformance was its below-average expenses.
For the fiscal year ended August 31, 2000, the fund's expense ratio was 0.51%,
compared with the 1.07% average for its Lipper category. All else being equal,
lower expenses mean higher yields and returns.

     The fund's performance also was aided by our "coupon barbell" strategy
--larger-than-average weightings in premium and discount bonds. Premiums trade
above par (face value) and carry interest payments above prevailing market
rates. Discount bonds trade below par and carry interest payments below
prevailing market rates.

WHAT WAS THE ATTRACTION OF THESE BONDS?

     We favored premium bonds because they boosted the fund's yield. The
discount bond side of the barbell resulted from when we bought discounts in
early 1999. At the time, we expected falling interest rates in response to
global economic weakness. We believed that the discount bonds would provide
"call protection" if interest rates fell and calls (bond redemptions by issuers
before maturity) became prevalent. This call protection effectively lengthened
the duration (heightened the interest rate sensitivity) of the portfolio last
year.

     The increasingly long duration of our discount bond holdings detracted from
performance when interest rates and bond yields rose for most of 1999. Even so,
we were reluctant to sell our discount bonds at distressed prices and abandon a
strategy we believed ultimately would benefit the fund.

WAS YOUR PATIENCE REWARDED?

     Yes, it was when the duration of par bonds began to extend dramatically
(their interest rate sensitivity increased) as interest rates climbed.
Meanwhile, the duration of discount bonds-- which had already extended in
earlier months--remained relatively stable, and the duration of premium bonds

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

extended less than par bonds. As a result, both discounts and premiums outpaced
par bonds and helped the fund outperform its peers.

     The market's spring and summer rally also favored our coupon barbell
strategy. Here's why: During the rally, par bonds started "trading to their call
date," meaning their prices reflected the likelihood that their issuers would
redeem them at the first possible call date. That essentially limited par bonds'
gains. In contrast, longer-duration discount bonds continued to rally.

WHY DID YOU SELL SOME DISCOUNT BONDS TOWARD THE END OF THE PERIOD?

     We wanted to lock in some of their strong performance and look for more
attractive values elsewhere. One place we found value was with bonds rated BBB.
In our view, BBB bonds gave us enough additional yield--as much as one half of
one percentage point more than an AAA security with a comparable maturity--to
compensate for increased credit risk. Although these additions brought the
fund's stake in BBB bonds to 9% of net assets, we maintained a high-quality
focus with approximately 90% in bonds rated A or higher. The average credit
quality of the portfolio as of August 31, 2000, was better than AA.

WHAT'S YOUR OUTLOOK FOR INTEREST RATES  AND BONDS?

     We're reasonably optimistic that the Federal Reserve's six interest rate
hikes during the last year or so will have their intended effect of slowing the
economy and keeping inflation under wraps. Rising interest rates around the
world also reinforce this view. Increasing worker productivity is another factor
to be reckoned with. Even the Fed has begun to support the view that, thanks to
productivity gains, the economy can enjoy good growth without inflation
spiraling out of control.

     The Fed could raise interest rates again before the end of the year if
consumer confidence and spending remain persistently strong. However, as oil
prices rise, the euro weakens, corporate earnings come under pressure, and the
stock market wavers, another rate hike grows increasingly unlikely.

     Municipal supply and demand also offer reasons for optimism. Given
municipal issuers' reduced debt issuance needs and the refinancing deterrent
caused by higher interest rates earlier this year, we expect the supply of
municipals to remain relatively low. If demand remains strong, municipal bond
prices should rise.

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

     We're likely to keep the fund's duration slightly longer than that of our
peers as long as the Fed appears unlikely to raise rates further. We're also
comfortable with the fund's credit quality, with the majority of our holdings
invested in AAA securities and a small amount in BBB bonds. As always, we'll
adhere to our preference for bonds that offer good value since that's the
philosophy that's helped us achieve our long-term success.

Statement 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 payables) 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, 2000

--------------------------------------------------------------------------------
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 (the 1940
Act) 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 policies 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, 2000, 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, 2000, accumulated net realized capital loss carryovers of
$565,637 for Limited-Term (expiring 2004 through 2008), $1,267,880 for
Intermediate-Term (expiring in 2008), and $1,238,946 for Long-Term (expiring in
2008) may be used to offset future taxable gains.

    Limited-Term, Intermediate-Term, and Long-Term have elected to treat
$43,337, $1,894,101, and $3,827,649, respectively, of net capital losses
incurred in the ten month period ended August 31, 2000, as having been incurred
in the following fiscal year.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the trust. 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 1940 Act
(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, 2000, the effective annual management fee was 0.51%, for
Limited-Term, Intermediate-Term, and Long-Term.

    Effective March 13, 2000, American Century Investment Services, Inc. (ACIS),
became a distributor of the trust.

    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, a
distributor of the trust, ACIS, 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 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 (the "Funds") at August 31, 2000, and the results of
their operations for the year then ended, the changes in net assets for the two
years in the period then ended, and the financial highlights for the three years
in the period then ended, in conformity with accounting principles generally
accepted in the United States of America. The financial highlights for each of
the two 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. These financial statements and financial highlights
(hereafter referred to as "financial statements") are the responsibility of the
Fund's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
financial statements in accordance with auditing standards generally accepted in
the United States of America, 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, 2000 by
correspondence with the custodian and brokers, provide a reasonable basis for
our opinion.

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 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
5-10 years.

     CALIFORNIA MUNICIPAL DEBT FUNDS (Long-Term Tax-Free) -- funds that invest
at least 65% of assets in municipal debt issues that are exempt from taxation in
California.

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 total returns, please refer to the "Financial
Highlights" on pages 30-32.

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.

* 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
maturityand yield for fixed-income securities.

STATISTICAL TERMINOLOGY

* NUMBER OF SECURITIES -- the number of different securities held by a fund ona
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 expensesand 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

    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.

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.

* 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.

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.
