Market Perspective

[photo of David MacEwen]

BY DAVID MACEWEN, CHIEF INVESTMENT OFFICER, FIXED INCOME

REACHING AN INFLECTION POINT

The 12 months ended August 31, 2006, provided two economic growth spurts, an
inflation scare, and the elevation of short-term interest rates to levels unseen
since the U.S. economy sputtered in 2001. Comparisons with 2001 hold some
merit--while the Wall Street consensus does not predict a downturn of the
magnitude of what happened five years ago, our 12-month reporting period
concluded with economic growth and interest rates teetering toward possible
declines in the next 12 months.

After two years of steady, mostly predictable, short-term interest rate hikes by
the Federal Reserve (the Fed) to harness inflation as the economy grew, the Fed
finally paused on August 8, 2006. We believe the Fed halted to assess the impact
of its 17 increases (which pushed its overnight rate target to a five-year high
of 5.25%) and to try to avoid repeating the mistake it had made in previous
cycles of pushing rates too high, tipping the economy into "hard landings."

INFLATION REMAINED A THREAT

Rising inflation complicated matters for the Fed--the 12-month percentage change
in the U.S. Labor Department's core consumer price index for August 2006 was
2.8%, the highest rate since November 2001. Some, including a voting member of
the Fed's interest rate policy committee, believed inflation at this level
warranted continued interest rate hikes. But the consensus forecasted instead
that the largely energy price-driven inflation threat would diminish as economic
growth declined. Indeed, inflation appeared to moderate at the end of the
reporting period as economic growth eased and energy prices fell.

CHALLENGING CONDITIONS FOR BONDS

Higher inflation and rising interest rates during much of the 12-month reporting
period caused price declines for most U.S. bonds. Generally speaking, however,
coupon returns offset price depreciation, resulting in modestly positive total
returns for the period. Longer-term taxable investment-grade securities, which
posted negative returns, were a notable exception. On the other hand, economic
growth and strong demand boosted high-yield and municipal sector returns, while
the Fed's seven rate hikes during the 12 months increased the yields and appeal
of money market securities.

California Tax-Free Money Market - Portfolio Commentary

PORTFOLIO MANAGER: TODD PARDULA

PERFORMANCE SUMMARY

California Tax-Free Money Market returned 2.70% for the 12 months ended August
31, 2006, outperforming the 2.58% average return of the 64 funds in Lipper's
"California Tax-Exempt Money Market Funds" category. The performance data on
page 3 show that the fund has generally outpaced its Lipper group average over
the long term, ranking in the top 29% of the group for the five-year period
ended August 31, 2006, and in the top 20% for the 10-year period ended August
31. California Tax-Free Money Market has offered very competitive returns
without investing in securities that are subject to the Alternative Minimum Tax
(AMT), unlike many of its Lipper peers.

MARKET PERSPECTIVE

As the Federal Reserve (the Fed) pushed short-term U.S. interest rates up 1.75
percentage points over the course of the year, money market yields rose
accordingly. Municipal money market yields also displayed their typical seasonal
fluctuations. Yields spiked in late December 2005 when money market supply
increased as dealers tried to clear their inventory before year end. But yields
fell again in early January as bond maturities and calls boosted demand for
money market securities. A similar cycle played out in April and May of 2006, as
investors withdrew funds from their money market accounts to pay taxes, causing
demand for money markets to plummet and yields to spike.

In June, the anticipation of a significant volume of bond maturities and calls
led to falling yields early in the month. But when the proceeds from those
maturities and calls failed to enter the short end of the muni market to the
extent that was expected and crossover buyers--such as corporations-- exited the
market, short muni yields jumped to their highest levels of the one-year period.

PORTFOLIO POSITIONING & STRATEGY

California Tax-Free Money Market's weighted average maturity (WAM) fell
throughout much of the period until June, when the majority of one-year notes
are issued in California. We took advantage of note season to extend the WAM by
participating in several note deals, primarily the Los Angeles City Tax and
Revenue Anticipation Notes (TRANs). These purchases pushed the WAM up to 36
days. By the end of August, California Tax-Free Money Market's WAM was 32 days,
about a week longer than the average WAM of its peers.

California Tax-Free Money Market - Portfolio Commentary

The portfolio's seven-day current yield rose from 1.98% to 3.01% during the
period, with some seasonal fluctuations along the way as described in the Market
Perspective section on the previous page. The portfolio's yield hit a high of
3.43% at the end of June when muni yields peaked, then fell back to more normal
levels in July, finishing the period at 3.01% on August 31. Most of the
portfolio's holdings remained in variable rate demand notes (VRDNs), short-term,
floating-rate municipal notes, which allowed the portfolio to capture higher
yields more quickly as interest rates rose. VRDNs made up 90.7% of the portfolio
at the end of August 2006.

HOW THE FUND FITS IN A DIVERSIFIED INVESTMENT STRATEGY

California Tax-Free Money Market is designed to supply the "cash" component in a
diversified investment portfolio, offering capital preservation and liquidity.
California Tax-Free Money Market provides current income that is exempt from
federal and California state income taxes, investing in high-quality, very
short-term debt securities issued by cities, counties, and other municipalities.

California Limited-Term Tax-Free - Portfolio Commentary

PORTFOLIO MANAGER: ALAN KRUSS

MR. KRUSS, VICE PRESIDENT AND PORTFOLIO MANAGER, JOINED AMERICAN CENTURY
INVESTMENTS IN 1997 AND BECAME A PORTFOLIO MANAGER IN 2001. IN APRIL 2006, MR.
KRUSS TOOK OVER CALIFORNIA LIMITED-TERM TAX-FREE'S TEAM-LEADER ROLE FROM ROBERT
MILLER, WHO REMAINS ON THE TEAM BUT NOW CONCENTRATES HIS DAY-TO-DAY EFFORTS ON
MANAGING OTHER MUNICIPAL PORTFOLIOS.

PERFORMANCE SUMMARY

California Limited-Term Tax-Free (Cal Limited-Term) returned 2.68% for the 12
months ended August 31, 2006. The bulk of this return stemmed from income, with
the fund's net asset value finishing slightly below where it began but above the
period's lows. Cal Limited-Term's modest gain reflected the challenging backdrop
for U.S. bonds, which contended with inflation running at its quickest pace
since 1991, erratic U.S. economic growth, and short-term interest rates at their
highest levels since 2001.

By comparison, the average return of the fund's peer group (18 California
short-intermediate municipal debt funds tracked by Lipper) was 2.49% while the
Lehman Brothers 3-Year Municipal Bond Index returned 2.27%, both performance
gauges underperforming Cal Limited-Term.

In the Market Perspective (page 2), we discuss the U.S. economic and broad bond
market backdrop for those returns. The Portfolio Positioning & Strategy section
on the next page highlights some of the strategies that we employed to help Cal
Limited-Term achieve its superior performance results for the 12 months.

YIELD SUMMARY

One of Cal Limited-Term's key objectives is to seek high current income that is
exempt from California and federal income taxes (the fund also seeks safety of
principal). With the Federal Reserve (the Fed) increasing short-term interest
rates seven times during the 12 months--from 3.50% in September 2005 to 5.25% by
the end of June 2006--in 25-basis-point (0.25%) increments, the fund's 30-day
SEC yield rose accordingly.

As of August 31, 2006, Cal Limited-Term's 30-day SEC yield was 3.29%, which
translated into the attractive tax-equivalent yields shown in the table at top
and was up from 2.90% as of August 31, 2005. By comparison, the Lipper group
average 30-day SEC yield was 3.13% at the end of the period, and it's worth
noting that we achieved Cal

California Limited-Term Tax-Free - Portfolio Commentary

Limited-Term's higher yield without purchasing bonds subject to the alternative
minimum tax.

PORTFOLIO POSITIONING & STRATEGY

Turning to portfolio-specific strategies, the foundations of our multi-layered,
repeatable investment approach remained central to our efforts and included
careful security selection, diligent investment monitoring, and thorough credit
analysis with the help of our long-tenured municipal credit research team.

Continuing a previously established trend, we actively emphasized lower-rated
investment-grade municipal bonds during the second half of the 12 months. The
generally higher yields of these securities propped up Cal Limited-Term's total
return amid the backdrop of rising short-term interest rates and bond yields
while simultaneously helping us to limit the portfolio's sensitivity to interest
rates. Lower-rated municipal bonds outperformed their higher-grade counterparts,
generally rewarding these efforts.

However, as the period began winding down, we felt that the contracted yield gap
between higher- and lower-rated investment-grade municipal bonds made the latter
less appealing from a risk/return standpoint than was previously the case. So
although we continued to examine any attractive opportunities that arose, we
didn't attempt to further increase the portfolio's allotment in municipal bonds
rated either single-A or BBB.

CALIFORNIA LIMITED-TERM TAX-FREE'S PLACE IN YOUR PORTFOLIO

Cal Limited-Term is designed to be a core bond holding and seeks safety of
principal and high current income by investing in debt securities issued by
cities, counties and municipalities, and U.S. territories.

Because municipal bonds typically don't move in lock-step with equities under
various economic and market scenarios, Cal Limited-Term potentially offers
diversification benefits for investors. But it's important to keep in mind that
even diversification does not ensure against losses.

California Tax-Free Bond - Portfolio Commentary

PORTFOLIO MANAGER: ROBERT MILLER

PERFORMANCE SUMMARY

California Tax-Free Bond (Cal Tax-Free Bond) returned 2.58% for the 12 months
ended August 31, 2006. Income comprised the bulk of this return, with the fund's
net asset value finishing below where it began but above the period's lows. Cal
Tax-Free Bond's modest gain reflected the challenging backdrop for municipal
securities, which contended with inflation running at its quickest pace since
1991, erratic U.S. economic growth, and short-term interest rates at their
highest levels since 2001.

By comparison, Cal Tax-Free Bond's Lipper peer group (comprised of 49 California
intermediate municipal debt funds) and the Lehman Brothers 5-Year GO Index
underperformed: the Lipper group average returned 2.38% while the Lehman index
returned 2.32%. In addition, the fund's five- and 10-year returns for the
periods ended August 31, 2006, also outpaced the returns of the Lipper group
average.

YIELD SUMMARY

Seeking high current income that is exempt from California and federal income
taxes is one of Cal Tax-Free Bond's key objectives (the fund also seeks safety
of principal). As of August 31, 2006, Cal Tax-Free Bond's 30-day SEC yield was
3.52%--which translated into the attractive tax-equivalent yields in the table
at top-- compared with the 3.10% Lipper group average. We feel that it's also
worth noting that we achieved Cal Tax-Free Bond's higher income stream without
purchasing bonds subject to the alternative minimum tax.

MUNICIPAL MARKET REVIEW

Heightened inflation concerns on the heels of record crude oil prices, erratic
U.S. economic growth, and seven additional short-term interest rate increases by
the Federal Reserve (the Fed) in 25-basis-point increments (0.25%) dampened the
performance of municipal bonds. Yields on short-term securities rose the most in
that environment, while yields on municipal bonds maturing in 20 or more years
edged narrowly lower, and bonds carrying non-investment-grade ratings (BB and
lower) produced substantially higher returns than their investment-grade
counterparts.

In addition, unlike the Treasury yield curve (a graph showing the relationship
between bond yields and maturities), the municipal bond yield curve didn't

California Tax-Free Bond - Portfolio Commentary

invert, which meant that investors could still earn additional income by taking
on more maturity risk. This drove up demand for municipal bonds, enabling them
to generally outperform taxable fixed-income securities.

PORTFOLIO POSITIONING & STRATEGY

With regard to portfolio-specific strategies, the foundations of our
multi-layered, repeatable investment approach remained central to our efforts
and included active security selection, diligent investment monitoring, and
thorough credit analysis with the help of our long-tenured municipal credit
research team.

For much of the 12 months, we positioned the portfolio to benefit from a
diminishing gap between the yields of short- and long-term municipal bonds, a
strategy for which we were rewarded. To accomplish this "barbell" bond maturity
structure (relative to the fund's Lipper peer group), we generally emphasized
short- and long-term bonds, while comparatively underweighting intermediate-term
securities.

Toward the end of the period, the yield-curve flattening appeared largely at an
end in light of moderating U.S. economic activity, the Fed on hold regarding
short-term interest rates, and optimism for diminished inflation going forward.

As a result, we adopted what we considered to be a "curve-neutral" approach
regarding the portfolio's bond maturity structure by adding intermediate-
maturity securities and simultaneously reducing short- and long-maturity
holdings. While doing so, we also adjusted Cal Tax-Free Bond's interest rate
sensitivity, electing a more in-line duration (a widely used gauge of interest
rate sensitivity) compared with the fund's Lipper peers.

CALIFORNIA TAX-FREE BOND'S PLACE IN YOUR PORTFOLIO

Cal Tax-Free Bond is designed to be a core bond holding and seeks safety of
principal and high current income by investing in debt securities issued by
cities, counties and municipalities, and U.S. territories.

Because municipal bonds typically don't move in lock-step with equities under
various economic and market scenarios, Cal Tax-Free Bond potentially offers
diversification benefits for investors. But it's important to keep in mind that
even diversification does not ensure against losses.

California Long-Term Tax-Free - Portfolio Commentary

PORTFOLIO MANAGERS: DAVID MACEWEN AND ROBERT MILLER

PERFORMANCE SUMMARY

California Long-Term Tax-Free (Cal Long-Term) returned 2.89% for the 12 months
ended August 31, 2006. This modest gain reflected a challenging backdrop for
U.S. bonds that included higher inflation, rising short-term interest rates, and
erratic U.S. economic growth. By comparison, the average return of the 121
California Municipal Debt Funds tracked by Lipper was narrowly lower at 2.81%.

Based on those returns, Cal Long-Term outperformed the Lipper group average for
the year ended August 31, 2006, as well as for the trailing five and 10 years;
however, the fund underperformed the Lehman Brothers Long-Term Municipal Bond
Index over those same periods. The higher returns of the Lehman index are
traceable to its comparatively longer duration (a widely used gauge of
sensitivity to interest rates) and the outperformance of the longest-term
municipal securities.

After the yield information that follows, we briefly discuss the municipal
market's performance before highlighting the strategies that we employed for Cal
Long-Term during the report period.

YIELD SUMMARY

One of Cal Long-Term's key objectives is to seek high current income that is
exempt from California and federal income taxes (the fund also seeks safety of
principal). As of August 31, 2006, the fund's 30-day SEC yield was 3.86%, which
translated into the attractive tax-equivalent yields shown in the table above.

By comparison, the Lipper group average 30-day SEC yield was 3.40% at the end of
the period. It's worth noting that we achieved Cal Long-Term's higher yield
without purchasing bonds subject to the alternative minimum tax, and that all
else held equal, a higher yield can translate into better peer-compared
performance.

MUNICIPAL MARKET REVIEW

The economic and market backdrop (detailed in the Market Perspective on page 2)
dampened the performance of municipal bonds. With the Federal Reserve ratcheting
up interest rates in an attempt to contain inflation, short-term bond yields
rose accordingly. Yields on intermediate-term municipal securities also
increased, while long-term bond yields edged lower.

California Long-Term Tax-Free - Portfolio Commentary

In that environment, and unlike the Treasury yield curve (a graph showing the
relationship between bond yields and maturities), the municipal bond yield curve
didn't invert, which meant that investors could still earn additional income by
taking on more maturity risk. This attracted investors and helped the municipal
market generally outperform the taxable market. Generally healthy economic
conditions, which translated into relatively solid tax revenues and credit
quality for municipal issuers, also benefited municipal securities.

PORTFOLIO POSITIONING & STRATEGY

On the portfolio front, the foundations of our multi-layered, repeatable
investment approach remained central to our efforts and included active security
selection, diligent investment monitoring, and thorough credit analysis with the
help of our long-tenured municipal credit research team.

During much of the period, we emphasized lower-rated investment-grade municipal
bonds and positioned the portfolio to benefit from a diminishing gap between the
yields of short- and long-term municipal bonds. From the credit-quality side,
that meant selectively adding single-A and BBB securities that we believed to be
attractive values. We also employed a bond maturity structure that more heavily
concentrated the portfolio in long-term securities rather than in short- or
intermediate-term bonds. Generally speaking, the market rewarded both of these
strategies.

Given the currently narrow gap between the yields of higher- and lower-rated
investment-grade bonds, and that the U.S. economy appears at an inflection
point, we've adopted what we consider to be a more in-line position compared
with Cal Long-Term's peer group where these strategies are concerned.

CALIFORNIA LONG-TERM TAX-FREE'S PLACE IN YOUR PORTFOLIO

Cal Long-Term is designed to be a core bond holding and seeks safety of
principal and high current income by investing in debt securities issued by
cities, counties and municipalities, and U.S. territories.

Because municipal bonds typically don't move in lock-step with equities, Cal
Long-Term potentially offers diversification benefits for investors. But it's
important to keep in mind that even diversification does not ensure against
losses.

(3) Security is a zero-coupon municipal bond. The rate indicated is the yield
    to maturity at purchase. Zero-coupon securities are issued at a substantial
    discount from their value at maturity.

(4) Security was purchased under Rule 144A of the Securities Act of 1933 or is
    a private placement and, unless registered under the Act or exempted from
    registration, may only be sold to qualified institutional investors. The
    aggregate value of restricted securities at August 31, 2006 was $21,496,345,

Shareholder Fee Examples (Unaudited)

Fund shareholders may incur two types of costs: (1) transaction costs, including
sales charges (loads) on purchase payments and redemption/exchange fees; and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in your fund and to compare these costs
with the ongoing cost of investing in other mutual funds.

The example is based on an investment of $1,000 made at the beginning of the
period and held for the entire period from March 1, 2006 to August 31, 2006.

ACTUAL EXPENSES

The table provides information about actual account values and actual expenses
for each class. You may use the information, together with the amount you
invested, to estimate the expenses that you paid over the period. First,
identify the share class you own. Then simply divide your account value by
$1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number under the heading "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond Fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
American Century may charge you a $12.50 semiannual account maintenance fee if
the value of those shares is less than $10,000. We will redeem shares
automatically in one of your accounts to pay the $12.50 fee. In determining your
total eligible investment amount, we will include your investments in all
PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered
under your Social Security number. PERSONAL ACCOUNTS include individual
accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell
Education Savings Accounts and IRAs (including traditional, Roth, Rollover,
SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you
have only business, business retirement, employer-sponsored or American Century
Brokerage accounts, you are currently not subject to this fee. We will not
charge the fee as long as you choose to manage your accounts exclusively online.
If you are subject to the Account Maintenance Fee, your account value could be
reduced by the fee amount.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The table also provides information about hypothetical account values and
hypothetical expenses based on the actual expense ratio of each class of your
fund and an assumed rate of return of 5% per year before expenses, which is not
the actual return of a fund's share class. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in your fund and other funds. To do so, compare this

Shareholder Fee Examples (Unaudited)

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption/exchange fees. Therefore, the table is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

(1) Expenses are equal to the class's annualized expense ratio listed in the
    table above, multiplied by the average account value over the period,
    multiplied by 184, the number of days in the most recent fiscal half-year,
    divided by 365, to reflect the one-half year period.

(2) During the six months ended August 31, 2006, the investment advisor waived a
    portion of the class's management fee.

(3) Ending account value assumes the return after waiver. The return would have
    been lower had fees not been waived and would have resulted in a lower
    ending account value.

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 Tax-Free Money Market Fund
(Tax-Free Money Market), California Limited-Term Tax-Free Fund (Limited-Term),
California Tax-Free Bond Fund (formerly California Intermediate-Term Tax-Free
Fund) (Tax-Free Bond), and California Long-Term Tax-Free Fund (Long-Term)
(collectively, the funds) are four funds in a series issued by the trust. The
funds are diversified under the 1940 Act. The funds' investment objectives are
to seek safety of principal and high current income that is exempt from federal
and California income taxes. Tax-Free Money Market, Limited-Term and Long-Term
invest primarily in municipal obligations with maturities based on the maturity
range described in that fund's name. Tax-Free Bond invests primarily in
municipal obligations of all maturity ranges. The following is a summary of the
funds' significant accounting policies.

SECURITY VALUATIONS -- Securities of Tax-Free Money Market are valued at
amortized cost, which approximates current market value. Securities of
Limited-Term, Tax-Free Bond and Long-Term are valued at current market value as
provided by a commercial pricing service or at the mean of the most recent bid
and asked prices. Debt securities maturing in greater than 60 days are valued at
current market value as provided by a commercial pricing service or at the mean
of the most recent bid and asked prices. Debt securities maturing within 60 days
may be valued at cost, plus or minus any amortized discount or premium. If the
funds determine that the market price of a portfolio security is not readily
available, or that the valuation methods mentioned above do not reflect the
security's fair value, such security is valued at its fair value as determined
by, or in accordance with procedures adopted by, the Board of Trustees or its
designee if such fair value determination would materially impact a fund's net
asset value. Circumstances that may cause the fund to fair value a security
include: an event occurred after the close of the exchange on which a portfolio
security principally trades (but before the close of the New York Stock
Exchange) that was likely to have changed the value of the security; a security
has been declared in default; or trading in a security has been halted during
the trading day.

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.

WHEN-ISSUED AND FORWARD COMMITMENTS -- The funds may engage in securities
transactions on a when-issued or forward commitment basis. Under these
arrangements, the securities' prices and yields are fixed on the date of the
commitment, but payment and delivery are scheduled for a future date. During
this period, securities are subject to market fluctuations. The funds will
segregate cash, cash equivalents or other appropriate liquid securities on their
records in amounts sufficient to meet the purchase price.

FUTURES CONTRACTS -- Limited-Term, Tax-Free Bond and Long-Term may enter into
futures contracts in order to manage the funds' exposure to changes in market
conditions. One of the risks of entering into futures contracts is the
possibility that the change in value of the contract may not correlate with the
changes in value of the underlying securities. Upon entering into a futures
contract, Limited-Term, Tax-Free Bond and Long-Term are required to deposit
either cash or securities in an amount equal to a certain percentage of the
contract value (initial margin). Subsequent payments (variation margin) are made
or received daily, in cash, by Limited-Term, Tax-Free Bond and Long-Term. The
variation margin is equal to the daily change in the contract value and is
recorded as unrealized gains and losses. Limited-Term, Tax-Free Bond and
Long-Term recognize a realized gain or loss when the contract is closed or
expires. Net realized and unrealized gains or losses occurring during the
holding period of futures contracts are a component of realized gain (loss) on
futures and swaps transactions and unrealized appreciation (depreciation) on
futures and swaps, respectively.

SWAP AGREEMENTS -- Limited-Term, Tax-Free Bond and Long-Term may enter into a
swap agreement in order to attempt to obtain or preserve a particular return or
spread at a lower cost than obtaining a return or spread through purchases
and/or sales of instruments in other markets; protect against currency
fluctuations; attempt to manage duration to protect against any increase in the
price of securities the funds anticipate purchasing at a later date; or gain
exposure to certain markets in the most economical way possible. A basic swap
agreement is a contract in which two parties agree to exchange the returns
earned or realized on predetermined investments or instruments. Limited-Term,
Tax-Free Bond and Long-Term will segregate cash, cash equivalents or other
appropriate liquid securities on their records in amounts sufficient to meet
requirements. Unrealized gains are reported as an asset

                                                                    (continued)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

and unrealized losses are reported as a liability on the Statement of Assets and
Liabilities. Swap agreements are valued daily and changes in value, including
the periodic amounts of interest to be paid or received on swaps are recorded as
unrealized appreciation (depreciation) on futures and swaps. Realized gain or
loss is recorded upon receipt or payment of a periodic settlement or termination
of swap agreements. The risks of entering into swap agreements include the
possible lack of liquidity, failure of the counterparty to meet its obligations,
and that there may be unfavorable changes in the underlying investments and
instruments.

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

DISTRIBUTIONS TO SHAREHOLDERS -- Distributions from net investment income are
declared daily and paid monthly. Distributions from net realized gains, if any,
are generally declared and paid annually. Tax-Free Money Market does not expect
to realize any long-term capital gains, and accordingly, does not expect to pay
any capital gains distributions.

INDEMNIFICATIONS -- Under the trust's organizational documents, its officers and
trustees are indemnified against certain liabilities arising out of the
performance of their duties to the funds. In addition, in the normal course of
business, the funds enter into contracts that provide general indemnifications.
The funds' maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the funds. The risk of material
loss from such claims is considered by management to be remote.

USE OF ESTIMATES -- The financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require management to make certain estimates and assumptions at the date of
the financial statements. Actual results could differ from these estimates.

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

MANAGEMENT FEES -- The trust has entered into a Management Agreement with
American Century Investment Management, Inc., (ACIM) (the investment advisor),
under which ACIM provides the funds with investment advisory and management
services in exchange for a single, unified management fee (the fee). The
Agreement provides that all expenses of the funds, except brokerage commissions,
taxes, portfolio insurance, interest, fees and expenses of those 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
computed and accrued daily based on the daily net assets of each specific class
of shares of each fund and paid monthly in arrears. The fee consists of (1) an
Investment Category Fee based on the daily net assets of the funds and certain
other accounts managed by the investment advisor that are in the same broad
investment category as each fund and (2) a Complex Fee based on the assets of
all the funds in the American Century family of funds. The rates for the
Investment Category Fee range from 0.1570% to 0.2700% for Tax-Free Money Market
and from 0.1625% to 0.2800% for Limited-Term, Tax-Free Bond, and Long-Term. The
rates for the Complex Fee range from 0.2500% to 0.3100%. Effective August 1,
2006 through July 31, 2007, ACIM has voluntarily agreed to waive 0.016% of its
management fee for Tax-Free Money Market. The waiver had no impact on the ratio
of operating expenses to average net assets and the ratio of net investment
income to average net assets. For the year ended August 31, 2006, the effective
annual management fee was 0.49% for each of the funds.

MONEY MARKET INSURANCE -- Tax-Free Money Market, along with other money market
funds managed by ACIM, has entered into an insurance agreement with Ambac
Assurance Corporation (Ambac). Ambac provides limited coverage for certain loss
events including issuer defaults as to payment of principal or interest and
insolvency of a credit enhancement provider. Tax-Free Money Market pays annual
premiums to Ambac, which are amortized daily over one year. For the year ended
August 31, 2006, the annualized ratio of money market insurance expense to
average net assets was 0.02%.

RELATED PARTIES -- Certain officers and trustees of the trust are also officers
and/or directors, and, as a group, controlling stockholders of American Century
Companies, Inc. (ACC), the parent of the trust's investment advisor, ACIM, the
distributor of the trust, American Century Investment Services, Inc., and the
trust's transfer agent, American Century Services, LLC.

                                                                    (continued)

2. FEES AND TRANSACTIONS WITH RELATED PARTIES (CONTINUED)

Limited-Term, Tax-Free Bond and Long-Term have a bank line of credit agreement
with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the funds and a wholly
owned subsidiary of J.P. Morgan Chase & Co. (JPM). JPM is an equity investor in
ACC.

3. INVESTMENT TRANSACTIONS

Investment transactions, excluding short-term investments, for the year ended
August 31, 2006, were  as follows:

- --------------------------------------------------------------------------------
                                LIMITED-TERM     TAX-FREE BOND      LONG-TERM
- --------------------------------------------------------------------------------
Cost of purchases                $26,800,663     $153,031,121      $139,176,816
- --------------------------------------------------------------------------------
Proceeds from sales              $40,365,082     $145,518,719      $187,955,632
- --------------------------------------------------------------------------------

All investment transactions for Tax-Free Money Market were considered short-term
during the year ended August 31, 2006.

4. BANK LINE OF CREDIT

Limited-Term, Tax-Free Bond and Long-Term, along with certain other funds
managed by ACIM or American Century Global Investment Management, Inc., have a
$500,000,000 unsecured bank line of credit agreement with JPMCB. Limited-Term,
Tax-Free Bond and Long-Term 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%. Limited-Term, Tax-Free Bond and Long-Term did
not borrow from the line during the year ended August 31, 2006.

5. RISK FACTORS

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. Income may be subject to state and local
taxes and, if applicable, the alternative minimum tax.

6. CORPORATE EVENT

On May 26, 2005, the Trustees approved a name and policy change for California
Intermediate-Term Tax-Free Fund. Effective January 1, 2006, the fund was renamed
to California Tax-Free Bond Fund and its investment policy was broadened to
allow its portfolio to hold investment-grade securities of all maturity ranges.

                                                                    (continued)

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

The book-basis 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 on the financial statements.

As of August 31, 2006, the components of distributable earnings on a tax-basis
and the federal tax cost of investments were as follows:

- -----------------------------------------------------------------------------------------------------
                                          TAX-FREE

The cost of investments for federal income tax purposes was the same as the cost
for financial statement purposes.

The accumulated capital losses listed above represent net capital loss
carryovers that may be used to offset future realized capital gains for federal
income tax purposes. The capital loss carryovers expire as follows:

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

The capital loss deferrals represent net capital losses incurred in the
ten-month period ended August 31, 2006. The funds have elected to treat such
losses as having been incurred in the following fiscal year for federal income
tax purposes.

                                                                    (continued)

8. RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2006, the Financial Accounting Standards Board issued Interpretation No.
48, "Accounting for Uncertainty in Income Taxes - an Interpretation of FASB
Statement No. 109" (the Interpretation). The Interpretation establishes a
minimum threshold for financial statement recognition of the benefit of
positions taken in filing tax returns (including whether an entity is taxable in
a particular jurisdiction), and requires certain expanded tax disclosures. The
Interpretation is effective for fiscal years beginning after December 15, 2006,
and is to be applied to all open tax years as of the date of effectiveness.
Management has recently begun to evaluate the application of the Interpretation
to each fund, and is not in a position at this time to estimate the significance
of its impact, if any, on each fund's financial statements.

9. OTHER TAX INFORMATION (UNAUDITED)

The following information is provided pursuant to provisions of the Internal
Revenue Code.

The funds hereby designate exempt interest and capital gain distributions for

Report of Independent Registered Public Accounting Firm

To the Trustees of the American Century California Tax-Free and Municipal Funds
and Shareholders of the California Tax-Free Money Market Fund, California
Limited-Term Tax-Free Fund, California Tax-Free Bond Fund and 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 Tax-Free Money
Market Fund, California Limited-Term Tax-Free Fund, California Tax-Free Bond
Fund and California Long-Term Tax-Free Fund (four of the five funds in the
American Century California Tax-Free and Municipal Funds, hereafter referred to
as the "Funds") at August 31, 2006, the results of each of their operations for
the year then ended, the changes in each of their net assets for each of the two
years in the period then ended and the financial highlights for each of the five
years in the period then ended, in conformity with accounting principles
generally accepted in the United States of America. These financial statements
and financial highlights (hereafter referred to as "financial statements") are
the responsibility of the Funds' management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
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, 2006 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Management

The individuals listed below serve as trustees or officers of the funds. Each
trustee serves until his or her successor is duly elected and qualified or until
he or she retires. Effective March 2004, mandatory retirement age for
independent trustees is 73. However, the mandatory retirement age may be
extended for a period not to exceed two years with the approval of the remaining
independent trustees. Those listed as interested trustees are "interested"
primarily by virtue of their engagement as officers of American Century
Companies, Inc. (ACC) or its wholly owned, direct or indirect, subsidiaries,
including the funds' investment advisor, American Century Investment Management,
Inc. (ACIM); the funds' principal underwriter, American Century Investment
Services, Inc. (ACIS); and the funds' transfer agent, American Century Services,
LLC (ACS).

The other trustees (more than three-fourths of the total number) are
independent; that is, they have never been employees or officers of, and have no
financial interest in, ACC or any of its wholly owned, direct or indirect,
subsidiaries, including ACIM, ACIS, and ACS. The trustees serve in this capacity
for eight registered investment companies in the American Century family of
funds.

All persons named as officers of the funds also serve in similar capacities for
the other 14 investment companies advised by ACIM or American Century Global
Investment Management, Inc. (ACGIM), a wholly owned subsidiary of ACIM, unless
otherwise noted. Only officers with policy-making functions are listed. No
officer is compensated for his or her service as an officer of the funds. The
listed officers are interested persons of the funds and are appointed or
re-appointed on an annual basis.

Approval of Management Agreements for California Tax-Free Money Market,
California Limited-Term Tax-Free, California Tax-Free Bond and California
Long-Term Tax-Free

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors or trustees (the "Directors") each
year. At American Century, this process is referred to as the "15(c) Process."
As a part of this process, the board reviews fund performance, shareholder
services, audit and compliance information, and a variety of other reports from
the advisor concerning fund operations. In addition to this annual review, the
board of directors oversees and evaluates on a continuous basis at its quarterly
meetings the nature and quality of significant services performed by the
advisor, fund performance, audit and compliance information, and a variety of
other reports relating to fund operations. The board, or committees of the
board, also holds special meetings as needed.

Under a Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for the board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year period, the Directors reviewed extensive data and information compiled
by the advisor and certain independent providers of evaluative data (the "15(c)
Providers") concerning California Tax-Free Money Market, California Limited-Term
Tax-Free, California Tax-Free Bond and California Long-Term Tax-Free (the
"funds") and the services provided to the funds under the management agreement.
The information considered and the discussions held at the meetings included,
but were not limited to:

* the nature, extent and quality of investment management, shareholder services
  and other services provided to the funds under the management agreement;

* reports on the advisor's activities relating to the wide range of programs and
  services the advisor provides to the funds and its shareholders on a routine
  and non-routine basis;

* data comparing the cost of owning the funds to the cost of owning a similar
  funds;

* data comparing the funds' performance to appropriate benchmarks and/or a peer
  group of other mutual funds with similar investment objectives and strategies;

* financial data showing the profitability of the funds to the advisor and the
  overall profitability of the advisor; and

* data comparing services provided and charges to other investment management
  clients of the advisor.

In keeping with its practice, the funds' board of directors held two regularly
scheduled meetings and one special meeting to review and discuss the information
provided by the advisor and to complete its negotiations with the advisor
regarding the renewal of the management agreement, including the setting of the
applicable advisory fee. The board also had the benefit of the advice of its
independent counsel throughout the period.

                                                                    (continued)

FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor, the
15(c) Providers, and the board's independent counsel, and evaluated such
information for each fund for which the board has responsibility. The Directors
did not identify any single factor as being all-important or controlling, and
each Director may have attributed different levels of importance to different
factors. In deciding to renew the agreement under the terms ultimately
determined by the board to be appropriate, the Directors' decision was based on
the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the funds. The board noted that under
the management agreement, the advisor provides or arranges at its own expense a
wide variety of services including:

* fund construction and design

* portfolio security selection

* initial capitalization/funding

* securities trading

* custody of fund assets

* daily valuation of the funds' portfolio

* shareholder servicing and transfer agency, including shareholder
  confirmations, recordkeeping and communications

* legal services

* regulatory and portfolio compliance

* financial reporting

* marketing and distribution

The Directors noted that many of these services have expanded over time both in
terms of quantity and complexity in response to shareholder demands, competition
in the industry and the changing regulatory environment. In performing their
evaluation, the Directors considered information received in connection with the
annual review, as well as information provided on an ongoing basis at their
regularly scheduled board and committee meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services
provided is quite complex and allows fund shareholders access to professional
money management, instant diversification of their investments within an asset
class, the opportunity to easily diversify among asset classes, and liquidity.
In evaluating investment performance, the board expects the advisor to manage
the funds in accordance with its investment objectives and approved strategies.
In providing these services, the advisor utilizes teams of investment
professionals (portfolio managers, analysts, research assistants, and securities
traders) who require extensive information technology, research, training,
compliance and other systems to conduct their business. At each quarterly
meeting the Directors review investment performance information for the funds,
together with comparative information for appropriate benchmarks and peer groups
of funds managed similarly to the funds. The Directors also review detailed
performance information during the 15(c) Process comparing the funds'
performance with that of similar funds not managed by the advisor.

                                                                    (continued)

If performance concerns are identified, the Directors discuss with the advisor
the reasons for such results (e.g., market conditions, security selection) and
any efforts being undertaken to improve performance. California Tax-Free Money
Market's performance for both the one and three year periods was above the
median for its peer group. California Limited-Term Tax-Free's and California
Long-Term Tax-Free's performance fell below the median for both the one and
three year periods during the past year. The board discussed the funds'
performance with the advisor and was satisfied with the efforts being undertaken
by the advisor. California Tax-Free Bond's performance was above the median for
the one year period and just below the median for the three year period.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at their regular
quarterly meetings, including the annual meeting concerning contract review, and
reports to the board. These reports include, but are not limited to, information
regarding the operational efficiency and accuracy of the shareholder and
transfer agency services provided, staffing levels, shareholder satisfaction (as
measured by external as well as internal sources), technology support, new
products and services offered to fund shareholders, securities trading
activities, portfolio valuation services, auditing services, and legal and
operational compliance activities. Certain aspects of shareholder and transfer
agency service level efficiency and the quality of securities trading activities
are measured by independent third party providers and are presented in
comparison to other fund groups not managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various services
to the funds, its profitability in managing the funds, its overall
profitability, and its financial condition. The Directors have reviewed with the
advisor the methodology used to prepare this financial information. This
financial information regarding the advisor is considered in order to evaluate
the advisor's financial condition, its ability to continue to provide services
under the management agreement, and the reasonableness of the current management
fee.

ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment
to providing quality services to shareholders and to conducting its business
ethically. They noted that the advisor's practices generally meet or exceed
industry best practices and that the advisor was not implicated in the industry
scandals of 2003 and 2004.

ECONOMIES OF SCALE. The Directors review reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes in
revenue, costs, and profitability. The Directors concluded that economies of
scale are difficult to measure and predict with precision, especially on a
fund-by-fund basis. This analysis is also complicated by the additional services
and content provided by the advisor and its reinvestment in its ability to
provide and

                                                                    (continued)

expand those services. Accordingly, the Directors also seek to evaluate
economies of scale by reviewing other information, such as year-over-year
profitability of the advisor generally, the profitability of its management of
the funds specifically, the expenses incurred by the advisor in providing
various functions to the funds, and the breakpoint fees of competitive funds not
managed by the advisor. The Directors believe the advisor is appropriately
sharing economies of scale through its competitive fee structure, fee
breakpoints as the fund complex and the funds increase in size, and through
reinvestment in its business to provide shareholders additional content and
services. In particular, separate breakpoint schedules based on the size of the
entire fund complex and on the size of the funds reflect the complexity of
assessing economies of scale.

COMPARISON TO OTHER FUNDS' FEES. The funds pay the advisor a single,
all-inclusive (or unified) management fee for providing all services necessary
for the management and operation of the funds, other than brokerage expenses,
taxes, interest, extraordinary expenses, and the fees and expenses of the funds'
independent directors (including their independent legal counsel). Under the
unified fee structure, the advisor is responsible for providing all investment
advisory, custody, audit, administrative, compliance, recordkeeping, marketing
and shareholder services, or arranging and supervising third parties to provide
such services. By contrast, most other funds are charged a variety of fees,
including an investment advisory fee, a transfer agency fee, an administrative
fee, distribution charges and other expenses. Other than their investment
advisory fees and Rule 12b-1 distribution fees, all other components of the
total fees charged by these other funds may be increased without shareholder
approval. The board believes the unified fee structure is a benefit to fund
shareholders because it clearly discloses to shareholders the cost of owning
fund shares, and, since the unified fee cannot be increased without a vote of
fund shareholders, it shifts to the advisor the risk of increased costs of
operating the fund and provides a direct incentive to minimize administrative
inefficiencies. Part of the Directors' analysis of fee levels involves reviewing
certain evaluative data compiled by an independent provider and comparing the
funds' unified fee to the total expense ratio of other funds in the funds' peer
group. The unified fees of California Tax-Free Money Market and California
Limited-Term Tax Free were below the median of the total expense ratios of their
peer groups. The unified fee of California Tax-Free Bond was in the lowest
quartile of the total expense ratios of its peer group. The unified fee of
California Long-Term Tax-Free was slightly above the lowest quartile of the
total expense ratios of its peer group.

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services to
advisory clients other than the funds. They observed that these varying types of
client accounts require different services and involve different regulatory and
entre-

                                                                    (continued)

preneurial risks than the management of the funds. The Directors analyzed this
information and concluded that the fees charged and services provided to the
funds were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the funds. They concluded that the advisor's primary business
is managing mutual funds and it generally does not use the fund or shareholder
information to generate profits in other lines of business, and therefore does
not derive any significant collateral benefits from them. The Directors noted
that the advisor receives proprietary research from broker-dealers that execute
fund portfolio transactions and concluded that this research is likely to
benefit fund shareholders. The Directors also determined that the advisor is
able to provide investment management services to certain clients other than the
funds, at least in part, due to its existing infrastructure built to serve the
fund complex. The Directors concluded, however, that the assets of those other
clients are not material to the analysis and, in any event, are included with
the assets of the funds to determine breakpoints in the funds' fee schedule,
provided they are managed using the same investment team and strategy.

CONCLUSIONS OF THE DIRECTORS

As a result of this process, the Directors, in the absence of particular
circumstances and assisted by the advice of legal counsel that is independent of
the advisor, taking into account all of the factors discussed above and the
information provided by the advisor concluded that the investment management
agreement between each of California Limited-Term Tax-Free, California Tax-Free
Bond and California Long-Term Tax-Free and the advisor is fair and reasonable in
light of the services provided and should be renewed.

The Directors of California Tax-Free Money Market negotiated a one-year waiver
by the advisor of a portion of the management fee. This waiver was proposed by
the Directors based on their review of the fund's percentile rank in its peer
group universe and the fact that the Directors seek as a general rule to have
total expense ratios of fixed income and money market funds in the lowest 25th
percentile of the fees of comparable funds. The advisor accepted the principle
of the fee waiver based on the fact that the lower fee will result in increased
competitiveness of the fund within its peer group universe. The fee waiver,
effective August 1, 2006, will result in a lowering of the management fee of the
fund by 0.016 percentage points below the current management fee. Following
these negotiations with the advisor, the Directors concluded that the investment
management agreement between the fund and the advisor is fair and reasonable in
light of the services provided and should be renewed.

Market Perspective

[photo of David MacEwen]

BY DAVID MACEWEN, CHIEF INVESTMENT OFFICER, FIXED INCOME

REACHING AN INFLECTION POINT

The 12 months ended August 31, 2006, provided two economic growth spurts, an
inflation scare, and the elevation of short-term interest rates to levels unseen
since the U.S. economy sputtered in 2001. Comparisons with 2001 hold some
merit--while the Wall Street consensus does not predict a downturn of the
magnitude of what happened five years ago, our 12-month reporting period
concluded with economic growth and interest rates teetering toward possible
declines in the next 12 months.

After two years of steady, mostly predictable, short-term interest rate hikes by
the Federal Reserve (the Fed) to harness inflation as the economy grew, the Fed
finally paused on August 8, 2006. We believe the Fed halted to assess the impact
of its 17 increases (which pushed its overnight rate target to a five-year high
of 5.25%) and to try to avoid repeating the mistake it had made in previous
cycles of pushing rates too high, tipping the economy into "hard landings."

INFLATION REMAINED A THREAT

Rising inflation complicated matters for the Fed--the 12-month percentage change
in the U.S. Labor Department's core consumer price index for August 2006 was
2.8%, the highest rate since November 2001. Some, including a voting member of
the Fed's interest rate policy committee, believed inflation at this level
warranted continued interest rate hikes. But the consensus forecasted instead
that the largely energy price-driven inflation threat would diminish as economic
growth declined. Indeed, inflation appeared to moderate at the end of the
reporting period as economic growth eased and energy prices fell.

CHALLENGING CONDITIONS FOR BONDS

Higher inflation and rising interest rates during much of the 12-month reporting
period caused price declines for most U.S. bonds. Generally speaking, however,
coupon returns offset price depreciation, resulting in modestly positive total
returns for the period. Longer-term taxable investment-grade securities, which
posted negative returns, were a notable exception. On the other hand, economic
growth and strong demand boosted high-yield and municipal sector returns, while
the Fed's seven rate hikes during the 12 months increased the yields and appeal
of money market securities.

California High-Yield Municipal - Portfolio Commentary

PORTFOLIO MANAGER: STEVEN PERMUT

PERFORMANCE SUMMARY

California High-Yield Municipal (Cal High-Yield) returned 3.80%* for the 12
months ended August 31, 2006, its lowest fiscal-year total return since 2003.
The fund's net asset value per share declined as interest rates rose (the fund's
yield climbed from 3.94% on August 31, 2005, to 4.03% a year later) but the
total return remained positive as the yield offset price declines in the
portfolio.

The Lehman Brothers Long-Term Municipal Bond Index returned 4.08%, also its
lowest trailing 12-month return since 2003 for periods ended August 31. Both the
fund and the index significantly outpaced the 2.81% average return of the fund's
Lipper group (121 primarily investment-grade California municipal debt funds
tracked by Lipper Inc.). They also outperformed the Lipper group average for the
five-year, 10-year, and since-inception periods ended August 31, 2006.

MUNICIPAL VS. TREASURY MARKET BEHAVIOR

Compared with the Treasury market, the municipal bond market was a relatively
favorable area in which to be invested for the 12 months ended August 31, 2006.
Long-term Treasury yields jumped 60-70 basis points during the period, with
corresponding bond price declines. By contrast, comparable AAA-rated general
obligation municipal bond yields rose considerably less, and even declined
slightly at the longest maturities.

Slower supply growth and sustained demand helped drive the municipal market's
outperformance. As interest rates rose, municipal issuance and refinancing
activity dwindled, limiting the increase in available bonds. Meanwhile investor
demand persisted because: 1) municipal credit quality typically improves with
economic expansion, 2) long-term municipal yields still compensated investors
for taking more maturity risk, unlike in the Treasury market, and 3) the
municipal market is typically less volatile than the Treasury market in rising
interest rate environments.

PUTTING FUND PERFORMANCE IN FURTHER CONTEXT

Cal High-Yield benefited largely from three factors: 1) the relative stability
of the municipal market, 2) outperformance in the high-yield municipal sector

California High-Yield Municipal - Portfolio Commentary

(which gave the fund an advantage over its largely investment-grade Lipper
group), and 3) disciplined management, including thorough credit analysis,
careful security selection, and diligent investment monitoring.

Two key features work in the high-yield municipal sector's favor in rising
interest rate environments: 1) greater sensitivity to economic growth and
improving credit quality than the broader municipal market, and 2) the high
yields help cushion against price declines. The resulting investor clamor for
high-yield municipals pushed municipal credit spreads (the yield difference
between high-yield and investment-grade municipals) to the lowest levels since
1999. High-yield corporate municipal bonds, particularly those issued in the
airline and tobacco sectors, performed especially well.

PORTFOLIO STRATEGY & OUTLOOK

We continued to overweight unrated bonds that met our credit quality criteria,
and land-secured bonds issued where we believe housing demand is greater than
supply. Unrated bonds boosted the fund's yield, while land-secured bonds provide
appreciation potential as the economy grows and/or projects are developed and
their credit risk diminishes.

We consider these strategies "all-weather." We believe land-secured bonds
provide lower long-term volatility than corporate municipal bonds, even as we
face a cooling housing market. The portfolio's land-secured bonds are backed by
special assessment taxes that don't fluctuate with property values. Corporate
municipal bonds, on the other hand, are subject to corporate profit volatility
and litigation risk.

HOW THE FUND FITS IN A DIVERSIFIED INVESTMENT STRATEGY

Cal High-Yield is designed to offer high-net-worth California residents high
levels of state and federal tax-free current income, capital appreciation
potential, and portfolio diversification benefits. The fund is best suited for
those accustomed to higher-risk securities and share-price fluctuation.
High-yield municipal bonds typically behave differently than equity, taxable,
and investment-grade bond investments under various economic and market
scenarios. Diversification does not ensure against loss, however.

Shareholder Fee Example (Unaudited)

Fund shareholders may incur two types of costs: (1) transaction costs, including
sales charges (loads) on purchase payments and redemption/exchange fees; and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in your fund and to compare these costs
with the ongoing cost of investing in other mutual funds.

The example is based on an investment of $1,000 made at the beginning of the
period and held for the entire period from March 1, 2006 to August 31, 2006.

ACTUAL EXPENSES

The table provides information about actual account values and actual expenses
for each class. You may use the information, together with the amount you
invested, to estimate the expenses that you paid over the period. First,
identify the share class you own. Then simply divide your account value by
$1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number under the heading "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond Fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
American Century may charge you a $12.50 semiannual account maintenance fee if
the value of those shares is less than $10,000. We will redeem shares
automatically in one of your accounts to pay the $12.50 fee. In determining your
total eligible investment amount, we will include your investments in all
PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered
under your Social Security number. PERSONAL ACCOUNTS include individual
accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell
Education Savings Accounts and IRAs (including traditional, Roth, Rollover,
SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you
have only business, business retirement, employer-sponsored or American Century
Brokerage accounts, you are currently not subject to this fee. We will not
charge the fee as long as you choose to manage your accounts exclusively online.
If you are subject to the Account Maintenance Fee, your account value could be
reduced by the fee amount.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The table also provides information about hypothetical account values and
hypothetical expenses based on the actual expense ratio of each class of your
fund and an assumed rate of return of 5% per year before expenses, which is not
the actual return of a fund's share class. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in your fund and other funds. To do so, compare this
5% hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

                                                                    (continued)

Shareholder Fee Example (Unaudited)

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption/exchange fees. Therefore, the table is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

Notes to Financial Statements

AUGUST 31, 2006

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
(the fund) is one fund in a series issued by the trust. The fund is
non-diversified under the 1940 Act. The fund's investment objective is to seek
high current income that is exempt from federal and California income taxes. The
fund pursues this objective by investing a portion of its assets in lower-rated
and unrated municipal securities. The following is a summary of the fund's
significant accounting policies.

MULTIPLE CLASS -- The fund is authorized to issue the Investor Class, the A
Class, the B Class and the C Class. The A Class may incur an initial sales
charge. The A Class, B Class and C Class may be subject to a contingent deferred
sales charge. The share classes differ principally in their respective sales
charges and shareholder servicing and distribution expenses and arrangements.
All shares of the fund represent an equal pro rata interest in the assets of the
class to which such shares belong, and have identical voting, dividend,
liquidation and other rights and the same terms and conditions, except for class
specific expenses and exclusive rights to vote on matters affecting only
individual classes. Income, non-class specific expenses, and realized and
unrealized capital gains and losses of the fund are allocated to each class of
shares based on their relative net assets.

SECURITY VALUATIONS -- Debt securities maturing in greater than 60 days are
valued at current market value as provided by a commercial pricing service or at
the mean of the most recent bid and asked prices. Debt securities maturing
within 60 days may be valued at cost, plus or minus any amortized discount or
premium. If the fund determines that the market price of a portfolio security is
not readily available, or that the valuation methods mentioned above do not
reflect the security's fair value, such security is valued at its fair value as
determined by, or in accordance with procedures adopted by, the Board of
Trustees or its designee if such fair value determination would materially
impact a fund's net asset value. Circumstances that may cause the fund to fair
value a security include: an event occurred after the close of the exchange on
which a portfolio security principally trades (but before the close of the New
York Stock Exchange) that was likely to have changed the value of the security;
a security has been declared in default; or trading in a security has been
halted during the trading day.

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.

WHEN-ISSUED AND FORWARD COMMITMENTS -- The fund may engage in securities
transactions on a when-issued or forward commitment basis. Under these
arrangements, the securities' prices and yields are fixed on the date of the
commitment, but payment and delivery are scheduled for a future date. During
this period, securities are subject to market fluctuations. The fund will
segregate cash, cash equivalents or other appropriate liquid securities on its
records in amounts sufficient to meet the purchase price.

FUTURES CONTRACTS -- The fund may enter into futures contracts in order to
manage the fund's exposure to changes in market conditions. One of the risks of
entering into futures contracts is the possibility that the change in value of
the contract may not correlate with the changes in value of the underlying
securities. Upon entering into a futures contract, the fund is required to
deposit either cash or securities in an amount equal to a certain percentage of
the contract value (initial margin). Subsequent payments (variation margin) are
made or received daily, in cash, by the fund. The variation margin is equal to
the daily change in the contract value and is recorded as unrealized gains and
losses. The fund recognizes a realized gain or loss when the contract is closed
or expires. Net realized and unrealized gains or losses occurring during the
holding period of futures contracts are a component of realized gain (loss) on
futures transactions and unrealized appreciation (depreciation) on futures,
respectively.

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

DISTRIBUTIONS TO SHAREHOLDERS -- Distributions from net investment income are
declared daily and paid monthly. Distributions from net realized gains, if any,
are generally declared and paid annually.

                                                                    (continued)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

INDEMNIFICATIONS -- Under the trust's organizational documents, its officers and
trustees are indemnified against certain liabilities arising out of the
performance of their duties to the fund. In addition, in the normal course of
business, the fund enters into contracts that provide general indemnifications.
The fund's maximum exposure under these arrangements is unknown as this would
involve future claims that may be made against the fund. The risk of material
loss from such claims is considered by management to be remote.
Use of Estimates -- The financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require management to make certain estimates and assumptions at the date of
the financial statements. Actual results could differ from these estimates.

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

MANAGEMENT FEES -- The trust has entered into a Management Agreement with
American Century Investment Management, Inc. (ACIM) (the investment advisor),
under which ACIM provides the fund with investment advisory and management
services in exchange for a single, unified management fee (the fee) per class.
The Agreement provides that all expenses of the fund, except brokerage
commissions, taxes, interest, fees and expenses of those 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 computed and
accrued daily based on the daily net assets of the specific class of shares of
the fund and paid monthly in arrears. The fee consists of (1) an Investment
Category Fee based on the daily net assets of the fund and certain other
accounts managed by the investment advisor that are in the same broad investment
category as the fund and (2) a Complex Fee based on the assets of all the funds
in the American Century family of funds. The rates for the Investment Category
Fee range from 0.1925% to 0.3100% and the rates for the Complex Fee range from
0.2500% to 0.3100%. For the year ended August 31, 2006, the effective annual
management fee for the Investor Class, A Class, B Class and C Class was 0.52%.

DISTRIBUTION AND SERVICE FEES -- The Board of Trustees has adopted a separate
Master Distribution and Individual Shareholder Services Plan for each of the A
Class, B Class and C Class (collectively, the plans), pursuant to Rule 12b-1 of
the 1940 Act. The plans provide that the B Class and C Class will pay American
Century Investment Services, Inc. (ACIS) the following annual distribution and
service fees:

- --------------------------------------------------------------------------------
                                                                     B & C
- --------------------------------------------------------------------------------
Distribution Fee                                                     0.75%
- --------------------------------------------------------------------------------
Service Fee                                                          0.25%
- --------------------------------------------------------------------------------

The plans provide that the A Class will pay ACIS an annual distribution and
service fee of 0.25%. The fees are computed and accrued daily based on each
class's daily net assets and paid monthly in arrears. The distribution fee
provides compensation for expenses incurred in connection with distributing
shares of the classes including, but not limited to, payments to brokers,
dealers, and financial institutions that have entered into sales agreements with
respect to shares of the fund. The service fee provides compensation for
individual shareholder services rendered by broker/dealers or other independent
financial intermediaries. Fees incurred under the plans during the year ended
August 31, 2006, are detailed in the Statement of Operations.

RELATED PARTIES -- Certain officers and trustees of the trust are also officers
and/or directors, and, as a group, controlling stockholders of American Century
Companies, Inc. (ACC), the parent of the trust's investment advisor, ACIM, the
distributor of the trust, ACIS, and the trust's transfer agent, American Century
Services, LLC.

The fund has a bank line of credit agreement with JPMorgan Chase Bank (JPMCB).
JPMCB is a custodian of the fund and a wholly owned subsidiary of J.P. Morgan
Chase & Co. (JPM). JPM is an equity investor in ACC.

                                                                    (continued)

5. BANK LINE OF CREDIT

The fund, along with certain other funds managed by ACIM or American Century
Global Investment Management, Inc., has a $500,000,000 unsecured bank line of
credit agreement with JPMCB. The fund 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 fund did not
borrow from the line during the year ended August 31, 2006.

6. RISK FACTORS

The fund concentrates its 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 fund invests primarily in
lower-rated debt securities, which are subject to substantial risks including
price volatility, liquidity risk, and default risk. Income may be subject to
state and local taxes and, if applicable, the alternative minimum tax.

7. FEDERAL TAX INFORMATION

The tax character of distributions paid during the years ended August 31, 2006
and August 31, 2005 were as follows:

- --------------------------------------------------------------------------------
                                                       2006             2005
- --------------------------------------------------------------------------------
DISTRIBUTIONS PAID FROM
- --------------------------------------------------------------------------------
Exempt income                                       $22,426,057     $18,882,595
- --------------------------------------------------------------------------------
Long-term capital gains                                      --              --
- --------------------------------------------------------------------------------

The book-basis 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 certain income items and net realized gains and losses for
financial statement and tax purposes, and may result in reclassification among
certain capital accounts on the financial statements.

                                                                    (continued)

7. FEDERAL TAX INFORMATION (CONTINUED)

As of August 31, 2006, the components of distributable earnings on a tax-basis
and the federal tax cost of investments were as follows:

- --------------------------------------------------------------------------------
Federal tax cost of investments                                    $489,210,277
================================================================================
Gross tax appreciation of investments                               $31,175,985
- -----------------------------------------------------------
Gross tax depreciation of investments                                   (14,869)
- --------------------------------------------------------------------------------
Net tax appreciation (depreciation) of investments                  $31,161,116
================================================================================
Accumulated capital losses                                            $(994,256)
- -----------------------------------------------------------
Capital loss deferral                                               $(1,849,032)
- --------------------------------------------------------------------------------

The cost of investments for federal income tax purposes was the same as the cost
for financial reporting purposes.

The accumulated capital losses listed above represent net capital loss
carryovers that may be used to offset future realized capital gains for federal
income tax purposes. The capital loss carryovers expire in 2009.

The capital loss deferrals represent net capital losses incurred in the
ten-month period ended August 31, 2006. The fund has elected to treat such
losses as having been incurred in the following fiscal year for federal income
tax purposes.

8. RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2006, the Financial Accounting Standards Board issued Interpretation No.
48, "Accounting for Uncertainty in Income Taxes -- an Interpretation of FASB
Statement No. 109" (the Interpretation). The Interpretation establishes a
minimum threshold for financial statement recognition of the benefit of
positions taken in filing tax returns (including whether an entity is taxable in
a particular jurisdiction), and requires certain expanded tax disclosures. The
Interpretation is effective for fiscal years beginning after December 15, 2006,
and is to be applied to all open tax years as of the date of effectiveness.
Management has recently begun to evaluate the application of the Interpretation
to the fund, and is not in a position at this time to estimate the significance
of its impact, if any, on the fund's financial statements.

9. OTHER TAX INFORMATION (UNAUDITED)

The following information is provided pursuant to provisions of the Internal
Revenue Code.

The fund hereby designates $22,309,537 of exempt interest distributions for the
fiscal year ended August 31, 2006.

(1) Total return assumes reinvestment of net investment income and capital gains
    distributions, if any. The total return of the classes may not precisely
    reflect the class expense differences because of the impact of calculating
    the net asset values to two decimal places. If net asset values were
    calculated to three decimal places, the total return differences would more
    closely reflect the class expense differences. The calculation of net asset
    values to two decimal places is made in accordance with SEC guidelines and
    does not result in any gain or loss of value between one class and another.

    Total returns for periods less than one year are not annualized. The total
    return of the classes may not precisely reflect the class expense
    differences because of the impact of calculating the net asset values to two
    decimal places. If net asset values were calculated to three decimal places,
    the total return differences would more closely reflect the class expense
    differences. The calculation of net asset values to two decimal places is
    made in accordance with SEC guidelines and does not result in any gain or
    loss of value between one class and another.

Report of Independent Registered Public Accounting Firm

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

In our opinion, the accompanying statement of assets and liabilities, including
the schedule 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 (one of the five funds in the American Century California Tax-Free and
Municipal Funds, hereafter referred to as the "Fund") at August 31, 2006, the
results of its operations for the year then ended, the changes in its net assets
for each of the two years in the period then ended and the financial highlights
for each of the periods presented, in conformity with accounting principles
generally accepted in the United States of America. 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 the standards of the
Public Company Accounting Oversight Board (United States). Those standards
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, 2006 by correspondence with the
custodian and brokers, provide a reasonable basis for our opinion.

Management

The individuals listed below serve as trustees or officers of the fund. Each
trustee serves until his or her successor is duly elected and qualified or until
he or she retires. Effective March 2004, mandatory retirement age for
independent trustees is 73. However, the mandatory retirement age may be
extended for a period not to exceed two years with the approval of the remaining
independent trustees. Those listed as interested trustees are "interested"
primarily by virtue of their engagement as officers of American Century
Companies, Inc. (ACC) or its wholly owned, direct or indirect, subsidiaries,
including the fund's investment advisor, American Century Investment Management,
Inc. (ACIM); the fund's principal underwriter, American Century Investment
Services, Inc. (ACIS); and the fund's transfer agent, American Century Services,
LLC (ACS).

The other trustees (more than three-fourths of the total number) are
independent; that is, they have never been employees or officers of, and have no
financial interest in, ACC or any of its wholly owned, direct or indirect,
subsidiaries, including ACIM, ACIS, and ACS. The trustees serve in this capacity
for eight registered investment companies in the American Century family of
funds.

All persons named as officers of the fund also serve in similar capacities for
the other 14 investment companies advised by ACIM or American Century Global
Investment Management, Inc. (ACGIM), a wholly owned subsidiary of ACIM, unless
otherwise noted. Only officers with policy-making functions are listed. No
officer is compensated for his or her service as an officer of the fund. The
listed officers are interested persons of the fund and are appointed or
re-appointed on an annual basis.

Approval of Management Agreement for California High-Yield Municipal

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors or trustees (the "Directors") each
year. At American Century, this process is referred to as the "15(c) Process."
As a part of this process, the board reviews fund performance, shareholder
services, audit and compliance information, and a variety of other reports from
the advisor concerning fund operations. In addition to this annual review, the
board of directors oversees and evaluates on a continuous basis at its quarterly
meetings the nature and quality of significant services performed by the
advisor, fund performance, audit and compliance information, and a variety of
other reports relating to fund operations. The board, or committees of the
board, also holds special meetings as needed.

Under a Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for the board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year period, the Directors reviewed extensive data and information compiled
by the advisor and certain independent providers of evaluative data (the "15(c)
Providers") concerning California High-Yield Municipal (the "fund") and the
services provided to the fund under the management agreement. The information
considered and the discussions held at the meetings included, but were not
limited to:

* the nature, extent and quality of investment management, shareholder services
  and other services provided to the fund under the management agreement;

* reports on the advisor's activities relating to the wide range of programs and
  services the advisor provides to the fund and its shareholders on a routine
  and non-routine basis;

* data comparing the cost of owning the fund to the cost of owning a similar
  fund;

* data comparing the fund's performance to appropriate benchmarks and/or a peer
  group of other mutual funds with similar investment objectives and strategies;

* financial data showing the profitability of the fund to the advisor and the
  overall profitability of the advisor; and

* data comparing services provided and charges to other investment management
  clients of the advisor.

In keeping with its practice, the fund's board of directors held two regularly
scheduled meetings and one special meeting to review and discuss the information
provided by the advisor and to complete its negotiations with the advisor
regarding the renewal of the management agreement, including the setting of the
applicable advisory fee. The board also had the benefit of the advice of its
independent counsel throughout the period.

                                                                    (continued)

Approval of Management Agreement for California High-Yield Municipal

FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor, the
15(c) Providers, and the board's independent counsel, and evaluated such
information for each fund for which the board has responsibility. The Directors
did not identify any single factor as being all-important or controlling, and
each Director may have attributed different levels of importance to different
factors. In deciding to renew the agreement under the terms ultimately
determined by the board to be appropriate, the Directors' decision was based on
the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the fund. The board noted that under the
management agreement, the advisor provides or arranges at its own expense a wide
variety of services including:

* fund construction and design

* portfolio security selection

* initial capitalization/funding

* securities trading

* custody of fund assets

* daily valuation of the fund's portfolio

* shareholder servicing and transfer agency, including shareholder
  confirmations, recordkeeping and communications

* legal services

* regulatory and portfolio compliance

* financial reporting

* marketing and distribution

The Directors noted that many of these services have expanded over time both in
terms of quantity and complexity in response to shareholder demands, competition
in the industry and the changing regulatory environment. In performing their
evaluation, the Directors considered information received in connection with the
annual review, as well as information provided on an ongoing basis at their
regularly scheduled board and committee meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services
provided is quite complex and allows fund shareholders access to professional
money management, instant diversification of their investments within an asset
class, the opportunity to easily diversify among asset classes, and liquidity.
In evaluating investment performance, the board expects the advisor to manage
the fund in accordance with its investment objectives and approved strategies.
In providing these services, the advisor utilizes teams of investment
professionals (portfolio managers, analysts, research assistants, and securities
traders) who require extensive information technology, research, training,
compliance and other systems to conduct their business. At each quarterly
meeting the Directors review investment performance information for the fund,
together with comparative information for appropriate benchmarks and peer groups
of funds managed similarly to the fund. The Directors also review detailed
performance information during the 15(c) Process comparing the fund's
performance with that of similar funds not managed by the advisor.

                                                                    (continued)


- ------
33


Approval of Management Agreement for California High-Yield Municipal

If performance concerns are identified, the Directors discuss with the advisor
the reasons for such results (e.g., market conditions, security selection) and
any efforts being undertaken to improve performance. The fund's performance for
both the one and three year periods was above the median for its peer group.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at their regular
quarterly meetings, including the annual meeting concerning contract review, and
reports to the board. These reports include, but are not limited to, information
regarding the operational efficiency and accuracy of the shareholder and
transfer agency services provided, staffing levels, shareholder satisfaction (as
measured by external as well as internal sources), technology support, new
products and services offered to fund shareholders, securities trading
activities, portfolio valuation services, auditing services, and legal and
operational compliance activities. Certain aspects of shareholder and transfer
agency service level efficiency and the quality of securities trading activities
are measured by independent third party providers and are presented in
comparison to other fund groups not managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various services
to the fund, its profitability in managing the fund, its overall profitability,
and its financial condition. The Directors have reviewed with the advisor the
methodology used to prepare this financial information. This financial
information regarding the advisor is considered in order to evaluate the
advisor's financial condition, its ability to continue to provide services under
the management agreement, and the reasonableness of the current management fee.

ETHICS OF THE ADVISOR. The Directors generally consider the advisor's commitment
to providing quality services to shareholders and to conducting its business
ethically. They noted that the advisor's practices generally meet or exceed
industry best practices and that the advisor was not implicated in the industry
scandals of 2003 and 2004.

ECONOMIES OF SCALE. The Directors review reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes in
revenue, costs, and profitability. The Directors concluded that economies of
scale are difficult to measure and predict with precision, especially on a
fund-by-fund basis. This analysis is also complicated by the additional services
and content provided by the advisor and its reinvestment in its ability to
provide and expand those services. Accordingly, the Directors also seek to
evaluate economies of scale by reviewing other information, such as
year-over-year profitability of the advisor generally, the profitability of its
management of the fund specifically, the expenses incurred by the advisor in
providing various functions to the fund, and the breakpoint fees of competitive
funds not managed by the advisor. The Directors believe the advisor is
appropriately sharing economies of scale through its competitive fee structure,

                                                                    (continued)


- ------
34


Approval of Management Agreement for California High-Yield Municipal

fee breakpoints as the fund complex and the fund increases in size, and through
reinvestment in its business to provide shareholders additional content and
services. In particular, separate breakpoint schedules based on the size of the
entire fund complex and on the size of the fund reflect the complexity of
assessing economies of scale.

COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single,
all-inclusive (or unified) management fee for providing all services necessary
for the management and operation of the fund, other than brokerage expenses,
taxes, interest, extraordinary expenses, and the fees and expenses of the fund's
independent directors (including their independent legal counsel). Under the
unified fee structure, the advisor is responsible for providing all investment
advisory, custody, audit, administrative, compliance, recordkeeping, marketing
and shareholder services, or arranging and supervising third parties to provide
such services. By contrast, most other funds are charged a variety of fees,
including an investment advisory fee, a transfer agency fee, an administrative
fee, distribution charges and other expenses. Other than their investment
advisory fees and Rule 12b-1 distribution fees, all other components of the
total fees charged by these other funds may be increased without shareholder
approval. The board believes the unified fee structure is a benefit to fund
shareholders because it clearly discloses to shareholders the cost of owning
fund shares, and, since the unified fee cannot be increased without a vote of
fund shareholders, it shifts to the advisor the risk of increased costs of
operating the fund and provides a direct incentive to minimize administrative
inefficiencies. Part of the Directors' analysis of fee levels involves reviewing
certain evaluative data compiled by an independent provider and comparing the
fund's unified fee to the total expense ratio of other funds in the fund's peer
group. The unified fee charged to shareholders of the fund was in the lowest
quartile of the total expense ratios of its peer group.

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services to
advisory clients other than the fund. They observed that these varying types of
client accounts require different services and involve different regulatory and
entrepreneurial risks than the management of the fund. The Directors analyzed
this information and concluded that the fees charged and services provided to
the fund were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the fund. They concluded that the advisor's primary business
is managing mutual funds and it generally does not use the fund or shareholder
information to generate profits in other lines of business, and therefore does
not derive any significant collateral benefits from them. The Directors noted
that the advisor receives proprietary research from broker-dealers that execute
fund portfolio transactions and concluded that this research is likely to
benefit fund shareholders.

                                                                    (continued)

35


Approval of Management Agreement for California High-Yield Municipal

The Directors also determined that the advisor is able to provide investment
management services to certain clients other than the fund, at least in part,
due to its existing infrastructure built to serve the fund complex. The
Directors concluded, however, that the assets of those other clients are not
material to the analysis and, in any event, are included with the assets of the
fund to determine breakpoints in the fund's fee schedule, provided they are
managed using the same investment team and strategy.

CONCLUSIONS OF THE DIRECTORS

As a result of this process, the Directors, in the absence of particular
circumstances and assisted by the advice of legal counsel that is independent of
the advisor, taking into account all of the factors discussed above and the
information provided by the advisor concluded that the investment management
agreement between the fund and the advisor is fair and reasonable in light of
the services provided and should be renewed.

Share Class Information

Four classes of shares are authorized for sale by the fund: Investor Class, A
Class, B Class, and C Class. The total expense ratios of A Class, B Class, and C
Class shares are higher than that of Investor Class shares. The fund is
available for purchase only through financial intermediaries by investors who
seek advice from them. The fund is closed to other investors, but those with
open accounts may make additional investments and reinvest dividends and capital
gains distributions as long as such accounts remain open.

INVESTOR CLASS shares are available for purchase in two ways: 1) directly from
American Century without any commissions or other fees; or 2) through certain
financial intermediaries (such as banks, broker-dealers, insurance companies and
investment advisors), which may require payment of a transaction fee to the
financial intermediary.

A CLASS shares are sold primarily through institutions such as investment
advisors, banks, broker-dealers, and insurance companies. A Class shares are
sold at their offering price, which is net asset value plus an initial sales
charge that ranges from 4.50% to 0.00% for fixed-income funds, depending on the
amount invested. The initial sales charge is deducted from the purchase amount
before it is invested. A Class shares may be subject to a contingent deferred
sales charge (CDSC). There is no CDSC on shares acquired through reinvestment of
dividends or capital gains. The prospectus contains information regarding
reductions and waivers of sales charges for A Class shares. The unified
management fee for A Class shares is the same as for Investor Class shares. A
Class shares also are subject to a 0.25% annual Rule 12b-1 distribution and
service fee.

B CLASS shares are sold primarily through institutions such as investment
advisors, banks, broker-dealers, and insurance companies. B Class shares
redeemed within six years of purchase are subject to a CDSC that declines from
5.00% during the first year after purchase to 0.00% after the sixth year. There
is no CDSC on shares acquired through reinvestment of dividends or capital
gains. The unified management fee for B Class shares is the same as for Investor
Class shares. B Class shares also are subject to a 1.00% annual Rule 12b-1
distribution and service fee. B Class shares automatically convert to A Class
shares (with lower expenses) eight years after their purchase date.

C CLASS shares are sold primarily through institutions such as investment
advisors, banks, broker-dealers, and insurance companies. C Class shares
redeemed within 12 months of purchase are subject to a CDSC of 1.00%. There is
no CDSC on shares acquired through reinvestment of dividends or capital gains.
The unified management fee for C Class shares is the same as for Investor Class
shares. C Class shares also are subject to a Rule 12b-1 distribution and service
fee of 1.00%.

All classes of shares represent a pro rata interest in the fund and generally
have the same rights and preferences.

         FY 2005:  $0

(e)(1)   In accordance  with paragraph  (c)(7)(i)(A)  of Rule 2-01 of Regulation

         audit  committee.  Pursuant  to  paragraph  (c)(7)(ii)  of Rule 2-01 of
         Regulation S-X, the registrant's  audit committee also pre-approves its
         accountant's  engagements for non-audit  services with the registrant's

         to the operations and financial reporting of the registrant.

         recent fiscal year that were  attributed  to work  performed by persons
         other than the principal  accountant's  full-time,  permanent employees
         was less than 50%.

(g)      The aggregate non-audit fees billed by the registrant's  accountant for
         services  rendered to the registrant,  and rendered to the registrant's
         investment  adviser  (not  including  any  sub-adviser  whose  role  is
         primarily portfolio management and is subcontracted with or overseen by
         another investment adviser), and any entity controlling, controlled by,
         or under common control with the adviser that provides ongoing services
         to the  registrant  for  each  of the  last  two  fiscal  years  of the

         adviser,  its parent  company,  and any entity  controlled by, or under
         common  control with the investment  adviser that provides  services to
         the  registrant,  which  services were not required to be  pre-approved
         pursuant to paragraph  (c)(7)(ii) of Rule 2-01 of  Regulation  S-X. The
         notification  provided to the  registrant's  audit  committee  included
         sufficient  details  regarding such services to allow the  registrant's
         audit  committee  to  consider  the  continuing   independence  of  its
         principal accountant.
