Our Message to You

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

The six months ended February 29, 2000, reminded California shareholders of the importance of their tax-free money market fund investment. The incredible growth of the state's "e-conomy" created unprecedented demand for tax-advantaged investments. In addition, stock market volatility made money market fund stability look attractive for investors with near-term financial goals.

In the broader U.S. economy, the Federal Reserve raised short-term interest rates twice in the last six months in an attempt to keep U.S. economic growth and inflation under control. While rates rose, inflation remained low, which helped money market instruments maintain their purchasing power.

The American Century California money market funds continued to shine in that environment. According to Lipper Inc., an independent mutual fund ranking service that evaluated 55 California money market funds, California Tax-Free and Municipal Money Market had above-average yields and below-average expenses. (See pages 4 and 11 for more performance information.)

We are proud of our funds' performance and the numerous ways we can help you meet your financial goals, but we are equally proud of our dedication to creating a positive, safe, and productive work environment for American Century staff. This commitment to the idea that "we're only as good as the way we treat our most junior team members" was recognized and rewarded in 1999, when American Century ranked in the top 40 of Fortune magazine's "100 Best Companies to Work For."

We do not take this recognition lightly — acknowledgements like this allow us to recruit talented and dedicated people, from service representatives to investment professionals. This "intellectual capital" is our most valuable resource and an essential one in our effort to provide you with excellent investment management and service.

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

Sincerely,

/s/ James E. Stowers

Why does my money fund yield fluctuate?

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

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

If you have any questions about our money market funds, call us toll free at 1-800-345-2021 or e-mail us at our Web site, www.americancentury.com.

Highlighting the difference between the California Tax-Free and Municipal Money Market funds

The AMT applies primarily to corporations and high-income individuals who are able to substantially reduce their regular tax liability with passive income, deductions, and exemptions. Because of their potential tax liability, AMT securities typically offer higher yields than non-AMT paper.

What it means for you — California Tax-Free Money Market may be more appropriate for investors who file under the AMT, while investors who aren't subject to the AMT may want to consider the California Municipal Money Market fund.

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

California Tax-Free Money Market — Q&A


[PHOTO OMITTED]

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

How did California Tax-Free Money Market perform during the six months ended February 29, 2000?

California Tax-Free Money Market produced a total return of 1.37%, beating the 1.28% average return of the 55 "California Tax-Exempt Money Market Funds" tracked by Lipper Inc. The portfolio's longer-term performance is also better than average (see the previous page).

How does the portfolio's yield compare?

The fund provided shareholders with more state and federal tax-free income than the average California money market fund. The portfolio's 7-day effective yield at the end of February was 2.54%, while the average yield of the funds in the Lipper group was 2.32%.

Why did California Tax-Free Money Market produce better yields and total returns than its Lipper group?

We have lower-than-average management fees. Other things being equal, lower expenses mean higher yields and returns for our shareholders. In addition, we work hard to maintain excellent business relationships with securities dealers who offer good rates on California money market securities.

Finally, we boosted our yield by increasing our weighting in tax-exempt commercial paper late last year, when it offered attractive yields compared with variable-rate notes. We also liked commercial paper because it gives us more flexibility in choosing our maturity date, and because it's backed by a letter of credit from a bank.

Can you talk a little more about California Tax-Free Money Market's yield, which was little changed even though interest rates rose?

The Federal Reserve increased short-term interest rates several times since last summer. However, tax-exempt money market fund yields don't necessarily move in lock-step with Fed policy. Supply and demand factors are also very important in determining yields for tax-exempt securities.

The dramatic growth of California's economy in recent years has created an imbalance in supply and demand for tax-free investments. The state's excellent economic health has reduced municipal borrowing needs, which in turn reduced new bond issuance. In addition, low unemployment and rising wages have pushed taxpayers into higher tax brackets and fueled demand for tax-exempt investments. Low supply and surging demand held down California money market yields, particularly in the last several months.

What's your outlook for the fund?

We expect to see continued strong demand for California money market securities, while supply should remain tight because new issuance is low. So even though we think the Fed will raise interest rates again in the coming months, yields on California securities aren't likely to rise significantly.

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

How did California Municipal Money Market perform during the six months ended February 29, 2000?

California Municipal Money Market produced a total return of 1.41%, beating the 1.28% average return of the 55 "California Tax-Exempt Money Market Funds" tracked by Lipper Inc.

In addition, California Municipal Money Market's return for the last 12 months ranked in the top 15% of its Lipper category. The portfolio's longer-term performance is also significantly better than average (see the previous page).

How does the portfolio's yield compare?

The fund provided shareholders with more state and federal tax-free income than the average California money market fund. The average yield of the funds in the Lipper group was 2.32%, while the portfolio's 7-day effective yield at the end of February was 2.72%. That's good enough to place in the top 10% of the Lipper group.

Why did California Municipal Money Market produce better yields and total returns than the Lipper group average?

We have lower-than-average management fees. Other things being equal, lower expenses mean higher yields and returns for our shareholders. In addition, we work hard to maintain excellent business relation ships with securities dealers who offer good rates on California money market securities.

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

Finally, we boosted our yield by adding some tax-exempt commercial paper late last year, when it offered attractive yields compared with variable-rate notes. We also liked commercial paper because it gives us more flexibility in choosing our maturity date, and because it's backed by a letter of credit from a bank.

Can you talk a little more about California Municipal Money Market's yield, which was little changed even though interest rates rose?

The Federal Reserve increased short-term interest rates several times since last summer. However, tax-exempt money market fund yields don't necessarily move in lock-step with Fed policy. Supply and demand factors are also very important in determining yields for tax-exempt securities.

The dramatic growth of California's economy in recent years has created an imbalance in supply and demand for tax-free investments. The state's excellent economic health has reduced municipal borrowing needs, which in turn reduced new bond issuance. In addition, low unemployment and rising wages have pushed taxpayers into higher tax brackets and fueled demand for tax-exempt investments. Low supply and surging demand held down California money market yields, particularly in the last several months.

What's your outlook for the fund?

We expect to see continued strong demand for California money market securities, while supply should remain tight because new issuance is low. So even though we think the Fed will raise interest rates again in the coming months, yields on California securities aren't likely to rise significantly.

Statements of Assets and Liabilities


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

Notes to Financial Statements


FEBRUARY 29, 2000 (UNAUDITED)


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

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

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

Investment Income — Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums.

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

Distributions to Shareholders — Distributions from net investment income are declared and credited daily and distributed monthly. The funds do not expect to realize any long-term capital gains, and accordingly, do not expect to pay any capital gains distributions.

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

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

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

Additional Information — Funds Distributor, Inc. (FDI) is a distributor of the trust. Certain officers of FDI are also officers of the trust.


2. Transactions with Related Parties

The trust has entered into a Management Agreement with American Century Investment Management, Inc. (ACIM) that provides each fund with investment advisory and management services in exchange for a single, unified management fee. Expenses excluded from this agreement are brokerage, taxes, portfolio insurance, interest, fees and expenses of the trustees who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses. The fee is calculated daily and paid monthly. It consists of an Investment Category Fee based on the average net assets of the funds in a specific fund's investment category and a Complex Fee based on the average net assets of all the funds managed by ACIM. The rates for the Investment Category Fee range from 0.1570% to 0.2700% and the rates for the Complex Fee range from 0.2900% to 0.3100%. For the six months ended February 29, 2000, the effective annual management fee for both funds was 0.49%.

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

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

Background Information


Investment Philosophy and Policies

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

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

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

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

California Tax-Free Money Market and California Municipal Money Market seek to provide interest income exempt from both federal and California state income taxes while maintaining a stable share price. The funds invest in high-quality California municipal money market securities with remaining maturities of 13 months or less.

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

Lipper Rankings

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

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

California Tax-Exempt Money Market Funds — funds that invest in high-quality California municipal obligations with dollar-weighted average maturities of less than 90 days.

Credit Rating Guidelines

Credit quality (the issuer's financial strength and the likelihood of timely payment of interest and principal) is a key factor in fixed-income investment analysis. Credit ratings issued by independent rating and research companies such as Standard & Poor's help quantify credit quality — the stronger the issuer, the higher the credit rating.

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

It's important to note that credit ratings are subjective. They reflect the opinions of the rating agencies that issue them and are not absolute standards of quality.

Fund Classifications

Please be aware that the fund's category may change over time. Therefore, it is important that you read a fund's prospectus or fund profile carefully before investing to ensure its objectives, policies, and risk potential are consistent with your needs.

Investment Objective

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

Risk

The classification of funds by risk category is based on quantitative historical measures as well as qualitative prospective measures. It is not intended to be a precise indicator of future risk or return levels. The degree of risk within each category can vary significantly, and some fund returns have historically been higher than more aggressive funds or lower than more conservative funds.

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

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

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

Our Message to You

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

Rising interest rates, falling bond prices, and a supply/demand imbalance at the long maturity end of the market presented difficult hurdles for American Century's California municipal bond funds during the six months ended February 29, 2000. In this environment, California High-Yield Municipal and Insured Tax-Free produced negative total returns, similar to other California municipal bond funds.

Despite challenging market conditions, the American Century California funds continued to provide competitive yields with low expenses — key factors that remain consistent no matter how bond market conditions may change.

As a result, these funds have typically beaten the average returns of their Lipper peer groups for the last 10 years. (See pages 4 and 12 for more performance information.)

We are proud of our funds' performance and the numerous ways we can help you meet your financial goals, but we are equally proud of our dedication to creating a positive, safe, and productive work environment for American Century staff. This commitment to the idea that "we're only as good as the way we treat our most junior team members" was recognized and rewarded in 1999, when American Century ranked in the top 40 of Fortune magazine's "100 Best Companies to Work For."

We do not take this recognition lightly — acknowledgements like this allow us to recruit talented and dedicated people, from service representatives to investment professionals. This "intellectual capital" is our most valuable resource and an essential one in our effort to provide you with excellent investment management and service.

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

Sincerely,

/s/ James E. Stowers

Market Perspective from Randall W. Merk

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

Lower Prices, Higher Yields

Strong economic growth, rising interest rates, and a booming stock market muted California municipal bond returns during the six months ended February 29, 2000. The short- and intermediate-term sectors of the municipal market posted small gains, while long-term bonds finished in negative territory (see the index returns table at right). Long-term municipal bonds also suffered in comparison with long-term Treasurys, which posted attractive returns amid government plans to reduce Treasury issuance and supply.

Continued strong U.S. economic growth fanned inflation fears and triggered higher interest rates. The U.S. economy grew at a 7.3% annual rate in the fourth quarter of 1999, its fastest rate in over 15 years, and unemployment remained near 30-year lows. In response, the Federal Reserve (the U.S. central bank) continued to raise short-term interest rates, pushing municipal bond yields higher and their prices lower.

As a result of the difficult municipal bond environment, yields are as high as they've been in several years. For an investor in the highest combined federal and California state tax bracket, a 30-year AAA-rated California municipal bond that yielded approximately 5.8% on February 29 (up from about 5.5% on August 31, 1999) offered a tax-equivalent yield of more than 10%. That compared very favorably with the 6.15% yield of the 30-year U.S. Treasury bond on February 29.

Technical Factors Turn Favorable

In the California municipal market, supply and demand conditions continued to improve. California's strong economy bolstered the financial stability of many municipal issuers and curtailed their borrowing needs. In addition, refinancing of old debt came to a virtual standstill as higher interest rates eliminated the financial incentive to retire old debt.

Meanwhile, investor demand firmed as municipals offered attractive prices and the highest tax-equivalent yields in several years. This was especially true among short- and intermediate-term California bonds — strong demand from individual investors held down California yields relative to the national municipal market.

High-Quality Bonds Outperform

Investment-grade municipal bonds outpaced lower-rated and non-rated bonds — the so-called "high-yield sector" — during the period. Much of this sector's underperformance can be attributed to heavy tax-loss selling in late 1999 and concerns about health care bonds, which tainted the entire high-yield market. We think the high-yield sell-off was overdone — California's economic strength lifted the credit quality of the high-yield sector, as well as the financial strength of the California municipal market as a whole.

"The Federal Reserve continued to raise short-term interest rates, pushing municipal bond yields higher and prices lower."

California High-Yield Municipal — Q&A


[PHOTO OMITTED]

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

How did California High-Yield Municipal perform during the six months ended February 29, 2000?

Rising interest rates and heavy tax-loss selling put pressure on the performance of high-yield municipal bonds and the fund. The fund returned -1.89%, compared with the -1.40% average total return of 110 "California Municipal Debt Funds" tracked by Lipper Inc.

The fund's longer-term results remained solid. For the three-, five-, and ten-year periods ended February 29, 2000, the fund ranked in the top 15% of its peer group.

The portfolio's below-average expenses and above-average yield helped build this track record. The fund's 30-day SEC yield as of February 29, 2000, was 5.56%, compared with the 4.74% average yield of the Lipper peer group.

Why did the fund trail its peers during the past six months?

The Lipper peer group for this fund includes many funds that emphasize investment-grade bonds. Higher-rated bonds outpaced lower-rated and unrated bonds — our main focus — during the past six months. These bonds were plagued primarily by "technical" supply and demand challenges (as opposed to "fundamental" economic or financial difficulties). The biggest problem was that they bore much of the brunt of year-end "tax-loss" selling. That's when investors sold underperforming municipal bonds to lock in losses and offset capital gains incurred elsewhere in their portfolios.

Tax-loss selling helped expand the available supply of high-yield bonds at a time when demand was very weak. This technical imbalance put pressure on high-yield bond prices.

What about the high-yield market's fundamental credit quality?

The overall credit quality of the high-yield sector continued to strengthen. Thanks to the state's strong economy, defaults by municipal issuers in California fell dramatically. The state enjoyed significant gains in job growth and personal wealth, which translated into a big jump in tax receipts. Despite all this good news, the unfavorable technical background overwhelmed the improvement in credit quality.

Perhaps the only exceptions to improving credit quality trends were health care bonds, which were beset by a variety of ills. The possible bankruptcy of a large, well-known HMO in Boston cast a pall over the entire national municipal health care sector. In addition, concerns about cutbacks in federal Medicare and Medicaid payments in response to the Balanced Budget Act of 1997 spread like a virus through the health care sector, raising questions about the industry's long-term profitability.

Fortunately, the fund was underweighted in health care bonds, which was a plus for performance. Among our few health care holdings, we emphasized hospitals and other providers who face little or no competition within their immediate geographic region. We also concentrated on those that receive limited federal payments, have a history of good financial performance, and a strong management team.

How did the fund's stake in land-secured bonds — the fund's largest sector concentration — hold up in this environment?

Even though housing supply, demand, and pricing trends were the strongest they've been in many years, housing bonds succumbed to the negative technical factors we discussed earlier.

Despite their recent difficulties, we continued to hold onto most of our land-secured bonds. We believe they are poised to perform better once technical imbalances in the bond market disappear. Housing is in short supply, with only one housing unit being built for every two new jobs created in California. Clearly, demand is quickly outstripping supply. Supply should be restricted further by the fact that many cities are reluctant to approve new housing developments because they require additional expenditures on roads, water, sewer, and other services.

How did you manage the fund's interest rate sensitivity?

As always, we made only modest adjustments to the fund's duration — a measure of its sensitivity to changes in interest rates — generally keeping it within 10% of the duration of the fund's peer group. Throughout the past six months, the fund's duration was a bit shorter than the average of its peer group.

What is your market outlook and how will it affect your strategy?

Because of our long-term value orientation, we focus primarily on the strength of the California economy, the financial health of high-yield municipal bond issuers, and the economic viability of the projects they're financing. As a result, we're pretty bullish on the high-yield market — technical factors will come and go, but the underlying economic and financial fundamentals of the bonds we're buying still appear strong.

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

As long as economic growth remains solid, which appears likely, we'll continue to emphasize land-secured bonds. If, however, the economy appears headed toward a sustained period of weakness, we would try to reduce our holdings in these bonds. At the same time, we'd likely increase our holdings in essential service revenue bonds — such as water and sewer bonds — which are typically affected less by the ebbs and flows of the economy.

"The overall credit quality of the high-yield sector continued to strengthen."

California Insured Tax-Free — Q&A


[PHOTO OMITTED]

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

How did California Insured Tax-Free perform during the six months ended February 29, 2000?

The fund outperformed its peers in a difficult period for municipal bond funds. California Insured Tax-Free returned -0.09%, beating the -0.70% average return of 23 "California Insured Municipal Debt Funds" tracked by Lipper Inc.

California Insured Tax-Free's longer-term returns also compared favorably. For the one-, three-, and five-year periods ended February 29, 2000, the fund ranked in the top third of its peer group (see page 12 for more performance comparisons). The fund's below-average expenses and above-average yield helped build this track record.


How low were California Insured Tax-Free's expenses and how high was its yield?

On February 29, 2000, the fund had an annualized expense ratio of 0.51%. That's less than half the 1.21% average expense ratio for the Lipper category. Helped by these low expenses, California Insured Tax-Free produced more state and federal tax-free income than the peer group average. As of February 29, the portfolio had a 30-day SEC yield of 5.00%, while the average California insured fund yielded 4.47%, according to Lipper. The fund's yield translated to a 9.13% tax-equivalent yield for California investors in the highest combined state and federal tax bracket.

Were there any other factors besides yield and expenses that helped the fund beat its peers during the past six months?

The portfolio's duration — a measure of its sensitivity to changes in interest rates — was slightly longer than the average duration of its peers. (The longer a fund's duration, the more the share price will rise and fall in response to interest rate changes.)

Shareholders may recall from the annual report six months ago that the fund had a large stake in discount bonds. These "discounts" trade below face value (par) because their interest coupons are below prevailing market rates. Since they're less likely to be refinanced, discounts tend to have a longer duration than par or premium bonds.

California Insured Tax-Free's longer duration and focus on discount bonds hurt performance in the final months of 1999 (when interest rates were rising and prices were falling). But they've boosted performance so far in 2000 as long-term municipal bonds have rallied.

Did any other strategic moves you made affect fund performance?

As the prices of discount bonds rebounded, we sold some to lock in their relatively strong performance. In addition, we continued to "barbell" the portfolio, balancing our remaining long-duration discount bonds with short-term investments. This helped prevent the fund's duration from extending further.

Certificates of participation securities (COPs) made up 25% of the fund's portfolio as of February 29. What made them attractive?

COPs aren't as easily understood as other types of municipal bonds, so their prices are more attractive and their yields are higher relative to other bonds. COPs are an alternative to general obligation financing — they don't require voter approval. They are used to finance many public facilities, such as city halls, convention centers, schools, prisons, and police stations. Moscone Center in San Francisco and the Los Angeles Convention Center were financed with COPs. With input from our credit research team, we focus on COPs issued by strong municipalities to finance essential facilities. For example, the fund owned a Foothill-De Anza Community College District COP used to finance much-needed educational facilities. This community college district benefits from the financial strength of one of California's wealthiest counties.

Many bond investors earned gains during this period, particularly if they invested in Treasury bonds. Why didn't municipal bonds keep pace with Treasurys?

Comparing Treasury and municipal bonds is like comparing computer-related stocks to pharmaceutical stocks — they're related, in a way, but the performance of one isn't necessarily going to mirror the other. Even among municipal securities there were large performance discrepancies, with shorter-term bonds and those with higher credit ratings clearly outperforming longer-term securities or those with less underlying financial strength.

While rising interest rates and a booming stock market caused demand for municipal bonds to decline, investors rushed to buy long-term Treasurys in advance of government plans to trim sales of new 30-year bonds. In addition, the Treasury bought back more than $1 billion of long-term bonds. This combination of strong demand and reduced supply kept Treasury yields lower than they might normally have been in a rising rate environment. While the supply of municipals also dwindled in 2000, the reduction wasn't as dramatic, and demand for municipals didn't rival the frenzy for Treasurys.

What's your outlook?

Over the long-term, we're optimistic. Rising interest rates have helped keep a lid on inflationary pressures, even in the wake of much better-than-expected economic growth. In an environment characterized by non-inflationary, moderate economic growth, municipal bonds could perform well. Over the short-term, however, market conditions may be choppy in anticipation of possible Federal Reserve rate hikes down the road.

Technical market factors also are a reason for optimism — firm demand is butting up against a shrinking supply of municipal bonds. Municipals currently offer attractive values relative to Treasurys. To the extent that investors embrace that value and boost demand, municipals are poised to benefit.

With that backdrop in mind, how will you position the fund?

We'll continue to work closely with our credit research team to look for attractively valued, financially strong securities, particularly in the COP sector. As for our duration, we may shorten it a bit if we feel that interest rates are poised to move substantially higher. Absent that scenario, however, we're likely to maintain our current duration position.

(1) Step-coupon security. Yield to maturity at purchase is indicated. These securities become interest bearing at a predetermined rate and future date and are purchased at a substantial discount from their value at maturity.
(2) Escrowed to maturity in U.S. government securities or state and local government securities.

Statements of Assets and Liabilities


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

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

Notes to Financial Statements


FEBRUARY 29, 2000 (UNAUDITED)


1. Organization and Summary of Significant Accounting Policies

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

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

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

Investment Income — Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums.

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

Distributions to Shareholders — Distributions from net investment income for the funds are declared daily and distributed monthly. Distributions from net realized gains for the funds are declared and paid annually.

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

High-Yield and Insured have elected to treat $3,315,692 and $390,233, respectively, of net capital losses incurred in the ten month period ended August 31, 1999, as having been incurred in the following fiscal year.

Futures Contracts — The funds may buy and sell interest rate futures contracts relating to debt securities. Futures transactions may be used to maintain cash reserves while remaining fully invested, to facilitate trading, to reduce transaction costs, or to pursue higher investment returns when a futures contract is priced more attractively than its underlying security or index. One of the risks of entering into futures contracts may include the possibility that the changes in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the funds are required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation margin) are made or received daily, in cash, by the funds. The variation margin is equal to the daily change in the contract value and is recorded as an unrealized gain or loss. The funds recognize a realized gain or loss when the contract is closed or expired. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on investments and unrealized appreciation (depreciation) on investments, respectively. There were no open futures contracts at February 29, 2000.

Additional Information — Funds Distributor, Inc. (FDI) is a distributor of the trust. Certain officers of FDI are also officers of the trust.


2. Transactions with Related Parties

The trust has entered into a Management Agreement with American Century Investment Management, Inc. (ACIM), under which ACIM provides each fund with investment advisory and management services in exchange for a single, unified management fee. The Agreement provides that all expenses of the funds, except brokerage, taxes, portfolio insurance, interest, fees and expenses of the Trustees who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is calculated daily and paid monthly. It consists of an Investment Category Fee based on the average net assets of the funds in a specific fund's investment category and a Complex Fee based on the average net assets of all the funds managed by ACIM. The rates for the Investment Category Fee range from 0.1925% to 0.3100% and 0.1625% to 0.2800%, for High-Yield and Insured, respectively. The rates for the Complex Fee range from 0.2900% to 0.3100%. For the six months ended February 29, 2000, the effective annual management fee was 0.54% and 0.51% for High-Yield and Insured, respectively.

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

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


3. Investment Transactions

Purchases of investment securities, excluding short-term investments, for High-Yield and Insured totaled $67,841,570 and $8,934,362, respectively. Sales of investment securities, excluding short-term investments, for High-Yield and Insured totaled $107,149,233 and $21,576,718, respectively.

As of February 29, 2000, accumulated net unrealized depreciation for High-Yield and Insured was $8,703,031 and $2,525,507, respectively, which consisted of unrealized appreciation of $4,551,029 and $4,694,115, respectively, and unrealized depreciation of $13,254,060 and $7,219,622, respectively. The aggregate cost of investments for federal income tax purposes was the same as the cost for financial reporting purposes.


4. Bank Loans

The funds, along with certain other funds managed by ACIM, entered into an unsecured $620,000,000 bank line of credit agreement with Chase Manhattan Bank. The funds may borrow money for temporary or emergency purposes to fund shareholder redemptions. Borrowings under the agreement bear interest at the Federal Funds rate plus 0.50%. The funds did not borrow from the line during the period ended February 29, 2000.

Background Information


Investment Philosophy and Policies

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

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

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

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

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

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

Comparative Indices

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

The Lehman Brothers Long-Term Municipal Bond Index is composed of more than 2,800 municipal bonds with maturities greater than 22 years. The average credit rating of the securities in the index is AA2/AA3. The average maturity of the index is approximately 27 years.

Lipper Rankings

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

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

California Municipal Debt Funds (High-Yield Municipal) — funds that invest at least 65% of assets in securities that are exempt from taxation in California.

California Insured Municipal Debt Funds (Insured Tax-Free) — funds that invest at least 65% of assets in securities that are exempt from taxation in California and insured as to timely payment of interest and repayment of principal.

Credit Rating Guidelines

Credit ratings are issued by independent research companies such as Standard & Poor's and Moody's. They are based on an issuer's financial strength and ability to pay interest and principal in a timely manner.

Securities rated AAA, AA, A, or BBB are considered "investment-grade" securities, meaning they are relatively safe from default. California High-Yield Municipal may invest more than 50% of its portfolio in securities that are below investment grade or not rated. Here are the most common credit ratings and their definitions:

It's important to note that credit ratings are subjective, reflecting the opinions of the rating agencies; they are not absolute standards of quality.

Fund Classifications

Please be aware that the fund's category may change over time. Therefore, it is important that you read a fund's prospectus or fund profile carefully before investing to ensure its objectives, policies, and risk potential are consistent with your needs.

Investment Objective

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

Risk

The classification of funds by risk category is based on quantitative historical measures as well as qualitative prospective measures. It is not intended to be a precise indicator of future risk or return levels. The degree of risk within each category can vary significantly, and some fund returns have historically been higher than more aggressive funds or lower than more conservative funds.

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

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

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

Rising interest rates and falling bond prices presented difficult hurdles for American Century's California municipal bond funds during the six months ended February 29, 2000. In this environment, the California Limited-Term and Intermediate-Term Tax-Free funds managed to produce modestly positive total returns, but the California Long-Term Tax-Free fund's greater interest-rate sensitivity resulted in a slightly negative return.

Despite challenging market conditions, these funds continued to provide competitive yields with low expenses—key factors that remain consistent no matter how bond market conditions may change. As a result, these funds have consistently beaten the average returns of their Lipper peer groups. (See pages 4, 11, and 19 for more performance information.)

We are proud of our funds' performance and the numerous ways we can help you meet your financial goals, but we are equally proud of our dedication to creating a positive, safe, and productive work environment for American Century staff. This commitment to the idea that "we're only as good as the way we treat our most junior team members" was recognized and rewarded in 1999, when American Century ranked in the top 40 of Fortune magazine's "100 Best Companies to Work For."

We do not take this recognition lightly — acknowledgements like this allow us to recruit talented and dedicated people, from service representatives to investment professionals. This "intellectual capital" is our most valuable resource and an essential one in our effort to provide you with excellent investment management and service.

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

Sincerely

Market Perspective from Randall W. Merk

Lower Prices, Higher Yields

Strong economic growth, rising interest rates, and a booming stock market muted California municipal bond returns during the six months ended February 29, 2000. The short- and intermediate-term sectors of the municipal market posted small gains, while long-term bonds finished in negative territory (see the index returns table at right). Long-term municipal bonds also suffered in comparison with long-term Treasurys, which posted attractive returns amid government plans to reduce Treasury issuance and supply.

Continued strong U.S. economic growth fanned inflation fears and triggered higher interest rates. The U.S. economy grew at a 7.3% annual rate in the fourth quarter of 1999, its fastest rate in over 15 years, and unemployment remained near 30-year lows. In response, the Federal Reserve (the U.S. central bank) continued to raise short-term interest rates, pushing municipal bond yields higher and prices lower.

As a result of the difficult municipal bond environment, yields are as high as they've been in several years. For an investor in the highest combined federal and California state tax bracket, a 30-year AAA-rated California municipal bond that yielded approximately 5.8% on February 29 (up from about 5.5% on August 31, 1999) offered a tax-equivalent yield of more than 10%. That compared very favorably with the 6.15% yield of the 30-year U.S. Treasury bond on February 29.

Technical Factors Remain Favorable

In the California municipal market, supply and demand conditions continued to improve. California's strong economy strengthened the financial stability of many municipal issuers and curtailed their borrowing needs. In addition, refinancing of old debt came to a virtual standstill as higher interest rates eliminated the financial incentive to retire old debt.

Meanwhile, investor demand firmed as municipals offered attractive prices and the highest tax-equivalent yields in several years. This was especially true among short- and intermediate-term California bonds—strong demand from individual investors held down California yields relative to the national municipal market.

High-Quality Bonds Outperform

Investment-grade municipal bonds outpaced lower-rated and non-rated bonds—the so-called "high-yield sector"—during the period. Much of high-yield's underperformance can be attributed to heavy tax-loss selling in late 1999 and concerns about healthcare bonds, which tainted the entire high-yield market. We think the high-yield sell-off was overdone—California's economic strength lifted the credit quality of the high-yield sector, as well as the financial strength of the California municipal market as a whole.

"The Federal Reserve continued to raise short-term interest rates, pushing municipal bond yields higher and prices lower."

California Limited-Term Tax-Free—Q&A


[PHOTO OMITTED]

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

How did California Limited-Term Tax-Free perform during the six months ended February 29, 2000?

Despite a difficult environment for fixed-income securities, California Limited-Term Tax-Free produced a 1.21% total return. That's significantly higher than the 0.79% average return of the 13 "California Short-Intermediate Municipal Debt Funds" tracked by Lipper Inc.

The portfolio's one-, three-, and five-year returns are also much better than average (see the previous page for detailed fund performance comparisons).

What about the portfolio's yield? How does it compare?

California Limited-Term Tax-Free also provided shareholders with more state and federal tax-free income than the average California short-intermediate bond fund. As of February 29, the portfolio's 30-day SEC yield was 4.11%, while the Lipper group average was 3.45%.

The portfolio's SEC yield translates into a tax-equivalent yield of 7.5% for California taxpayers in the highest in come tax bracket (see the table at right). By comparison, at the end of February, two- and five-year Treasury notes were yielding 6.58% and 6.64%, respectively.

Why did California Limited-Term Tax-Free produce better yields and total returns than its Lipper group?

One reason is that our management expenses are quite a bit lower than those of the average California short-intermediate municipal bond fund. Other things being equal, lower expenses should translate into higher yields and returns.

But perhaps the biggest reason for our solid relative performance was the way we managed the fund's duration over the last six months.

Can you tell us what duration is and how you managed it?

Duration measures a bond or bond fund's sensitivity to changes in interest rates. The shorter a bond or fund's duration, the less its price fluctuates when interest rates change. A longer duration signals greater price sensitivity to rate changes. Interest rates and bond prices move in opposite directions, so you want a shorter duration when interest rates are rising and a longer duration when interest rates fall.

We kept duration relatively short, around three years, for much of the last year. That positioning helped fund performance, particularly during the last several months of 1999, when interest rates rose.

Are higher interest rates why the fund's yield increased in recent months?

Yes. Unprecedented U.S. economic growth and a tight labor market led the Federal Reserve to raise short-term interest rates several times since last summer. The Fed has been trying to tap the brakes on the economy and bring growth back below its speed limit for inflation.

That policy goes a long way toward explaining why the fund's yield rose from 3.72% to 4.11% in the past six months. But another reason for the fund's higher yield is that we added what we think are good bonds with attractive yields.

Can you give examples of some of the bonds you liked?

In the last six months, we bought some Puerto Rico municipals with attractive yields. We added these bonds because they offered a good yield pick-up over California securities with a comparable maturity and credit rating. Interest payments by bonds issued by Puerto Rico and other United States territories are free from state and federal taxes for investors in all 50 states.

In addition, we held a modest position in municipal hospital bonds. These bonds offered significantly higher yields than most other municipal securities. That's because the hospital industry is out of favor with many investors, thanks to shrinking profit margins. However, our experienced credit research team believes that the issues we own are "diamonds in the rough"—solid credits that have been tarred unfairly with the same broad brush as the rest of the industry.

California's economy has been very strong. How has that affected the fund?

The tremendous growth of California's economy is generally holding down California municipal bond fund yields. The supply of new bonds is scarce because municipalities' borrowing needs decrease as their financial health improves.

In addition, low unemployment and unprecedented wealth creation have pushed taxpayers into higher tax brackets, and that has fueled greater demand for tax-exempt investments. Less supply and more demand have caused yields on California municipal bonds to decrease relative to national market rates.

A red-hot economy has also led to healthier municipal balance sheets. In general, that means improved credit quality for California state and local municipal bond issuers.

What's your outlook for interest rates?

We expect the Federal Reserve to continue to raise interest rates through the first half of 2000 or so. But we don't see the fundamentals of the California municipal market changing anytime soon, so we're likely to continue to see strong demand for California bonds. In addition, we expect supply to remain tight because issuers have limited borrowing needs. That means that the fund's yield is likely to increase only modestly going forward even if we're right and the Fed raises rates again.

Given that outlook, how will you position the portfolio?

In terms of duration, we expect to position the fund a little closer to neutral because we think it's unlikely short-term California municipal rates will rise sharply. As far as sector allocation is concerned, we'll continue to monitor the spread, or difference in yield, between California and Puerto Rico bonds. We'll hang on to the Puerto Rico municipals as long as the yield spread remains relatively wide. But if spreads narrow—meaning Puerto Rico bonds outperform California securities—we'd likely take some profits by selling these securities and moving back into California bonds.

"The portfolio's SEC yield translates into a tax-equivalent yield of 7.5% for California taxpayers in the highest income tax bracket."

California Intermediate-Term Tax-Free—Q&A


[PHOTO OMITTED]

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

How did California Intermediate-Term Tax-Free perform during the six months ended February 29, 2000?

The fund posted a positive return despite rising interest rates. For the six-month period, California Intermediate-Term Tax-Free returned 0.90%, which beat the 0.58% average return of the 28 "California Intermediate Municipal Debt Funds" tracked by Lipper Inc.

The fund has consistently outperformed the average California intermediate municipal fund over longer time periods as well (see the previous page).

Why did the fund beat its Lipper group average?

It's partly because of the fund's low expenses. California Intermediate-Term Tax-Free has an annual expense ratio of 0.51%, while its Lipper group averages 0.75%.

Another factor was some adjustments we made to the fund's duration, shortening it in the fourth quarter of 1999.

What was the advantage of a shorter duration?

Duration is a measure of the fund's price volatility as interest rates change. When interest rates rise—as they did over the past six months—the fund's share price typically falls, so we wanted a shorter duration because it helps minimize price declines.

California Intermediate-Term Tax-Free's duration was 5.7 years at the start of the six-month period, but we shortened it to 5.2 years by the end of 1999. We added some shorter-term bonds to the portfolio in December when their yields spiked higher.

Why did their yields jump?

It was a Y2K effect. In mid-December, trading in the California municipal market slowed to a crawl because investors were afraid to commit cash ahead of any possible problems at year-end. The lack of demand in some parts of the market caused yields to rise dramatically, and we were able to find a number of short-term bonds with very attractive yields. These purchases helped shorten the fund's duration and increase its yield at the same time.

Once January rolled around and everything turned out fine, the situation reversed—yields fell back down to previous levels, and our bonds got some nice price gains.

Puerto Rico bonds now make up 11% of California Intermediate-Term Tax-Free's portfolio. Why are these bonds such a large part of the portfolio?

They help boost the fund's yield. Puerto Rico bonds have all the same benefits of California bonds—the interest is free from both federal and state taxes (this is true in all 50 states). But we've been able to get higher yields on Puerto Rico bonds than we could on comparable California bonds.

Among short- and intermediate-term bonds, California municipal yields were lower than municipal yields nationally for most of 1999, and this disparity has become even more pronounced so far in 2000.

Why are California yields so low?

It's a supply and demand imbalance. Issuance of municipal bonds in California has been very light—huge tax revenues produced by a strong economy have reduced the state's borrowing needs.

In contrast, demand for short- and intermediate-term California municipal bonds is extremely heavy. It's mainly individual investors, not institutions or mutual funds. Many of these individuals are taking some of the wealth they've amassed in the technology or entertainment industries and socking it away in municipal bonds.

The combination of high demand and low supply has kept California yields down relative to other states. By the end of February, yields on intermediate-term California municipal bonds were more than 30 basis points (0.30%) lower than the national municipal market, compared with about 10 basis points six months ago.

Do you expect this situation to continue?

More than likely, at least in the near future. Demand from individual investors hasn't shown any sign of slowing down, and it may even pick up if the stock market continues to do well.

The California economy is as healthy as it's been in at least a decade, so issuance will probably continue to be on the low side. It's also good news for the state's credit quality.

The national economy is in great shape, too, and that means the Federal Reserve will almost certainly raise short-term interest rates several more times to slow it down.

Nonetheless, municipal yields have gone up quite a bit in the past year, and we think that most of the rise in yields is behind us.

How do you plan to position the portfolio going forward?

We may look to extend the fund's duration a little in the next six months. That would put the fund in a better position if and when yields peak and start to come back down.

Right now, the fund holds a balance of longer-term bonds and short-term bonds. This is known as a "barbell" because we're heavy at both ends of the maturity scale. The reason for this is the big yield gap that currently exists between intermediate- and long-term California bonds. We bought longer-term bonds to pick up that extra yield, and we offset them with short-term bonds to keep the fund's duration from extending.

Recently, though, that yield gap has started to narrow, and if it continues to do so, we may unwind the barbell position and focus our purchases on intermediate-term bonds.

"The fund has consistently outperformed the average California intermediate municipal fund."

The graph at left shows the growth of a $10,000 investment in the fund over 10 years, while the graph below shows the fund's year-by-year performance. The Lehman Long-Term Municipal Index is provided for comparison in each graph. California Long-Term Tax-Free's total returns include operating expenses (such as transaction costs and management fees) that reduce returns, while the total returns of the index do not. Past performance does not guarantee future results. Investment return and principal value will fluctuate, and redemption value may be more or less than original cost.

Additionally, California Long-Term Tax-Free produced more state and federal tax-free income than its peers. The fund's 30-day SEC yield as of February 29 was 5.19%, compared with the 4.74% average yield of the Lipper group. The fund's yield translates into a tax-equivalent yield of about 9.5% for investors in the highest combined state and federal income tax bracket (see the table at left).

Why did the fund beat its peers during the past six months?

A key ingredient in the fund's outperformance was its below-average expenses. As of February 29, the fund's expense ratio was 0.51%, compared with the 1.07% average for its Lipper group. All else being equal, lower expenses mean higher yields and returns.

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

The fund's longer duration hurt performance in the final months of 1999 when interest rates rose and prices fell, but it has boosted performance so far in 2000 as long-term municipal bonds have rallied.

How did the fund end up with a longer duration in a rising interest rate environment?

Our longer duration was partly a function of our larger-than-average weighting in discount bonds. Discount bonds trade below par (face) value and carry interest payments below prevailing market rates. As a result, they tend to have longer durations because they are less likely to be called (refinanced) by their issuers before maturity.

We loaded up on discount bonds more than a year ago when our outlook called for falling interest rates in response to global economic weakness and low inflation. We thought the discount bonds would give the portfolio "call protection" if, as we expected, interest rates fell and calls became prevalent. This call protection effectively lengthened the duration of the portfolio.

The discount bonds detracted from performance when interest rates and bond yields rose during the final four months of 1999. Even so, we were reluctant to sell discount bonds at distressed prices and walk away from a strategy we believed ultimately would benefit the fund.

That patience was rewarded in early 2000 when long-term municipal bonds rallied and discount bonds became more attractive, boosting fund performance. The stronger market also presented us with opportunities to sell some of our discount holdings at attractive prices. We redeployed some of the proceeds of those sales into bonds rated BBB.

Why were BBB-rated bonds attractive? And what types did you buy?

The spread — or difference in yield — between bonds rated AAA and those rated BBB widened significantly. In other words, bonds rated BBB offered an increasing yield advantage over higher-rated bonds. By the end of February, for example, a typical 30-year BBB bond offered about 50 basis points (0.50%) more yield than a AAA-rated security with a comparable maturity.

In terms of sectors, we focused on BBB-rated tax allocation bonds, which are used to finance improvements in redevelopment areas (such as urban neighborhoods).

What's your outlook for interest rates and the bond market?

We're cautiously optimistic. Inflation has remained in check, despite stronger-than-expected U.S. economic growth. The broad U.S. inflation gauges haven't changed much recently. Even the recent rise in the price of oil, which topped $30 a barrel earlier this year, hasn't affected the inflation picture much.

Although our long-term outlook is constructive, it's quite likely that the bond market will gyrate over the short-term as the war between "good" — low inflation — and "evil" — tight labor markets and wage pressures — rages on. It's quite possible that the Federal Reserve will continue to raise interest rates in their pre-emptive battle against inflation. Our view, however, is that non-inflationary, moderate economic growth will ultimately triumph, providing a favorable backdrop for bonds.

There's another reason for optimism — municipal bonds currently offer attractive values relative to U.S. Treasury securities. Long-term municipal bonds have higher yields than Treasury bonds before factoring in their tax benefits. To the extent that investors gravitate toward that value, demand should strengthen and benefit municipals. We also expect supply to remain low, which will likely continue to help the municipal bond market.

Given your outlook, what are your plans for the fund over the next six months?

We're likely to keep the fund's duration slightly longer than that of its peers as long as our outlook is upbeat. But most importantly, we plan to stick with the same value orientation that has contributed to our long-term success. We'll continue working with our credit research staff to uncover attractively valued securities that have the potential to enhance returns. Over the near term, we think some of those values will come from the BBB-rated sector.

(1) Security is a zero-coupon municipal bond. The yield to maturity at purchase is indicated. Zero-coupon securities are purchased at a substantial discount from their value at maturity.
(2) Escrowed to maturity in U.S. government securities or state and local government securities.
(3) Inverse floaters have interest rates that move inversely to market interest rates. Inverse floaters typically have durations longer than long-term bonds, which may cause their value to be more volatile than long-term bonds when interest rates change.

Statements of Assets and Liabilities


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

                                                                         INTERMEDIATE-

Notes to Financial Statements


FEBRUARY 29, 2000 (UNAUDITED)


1. Organization and Summary of Significant Accounting Policies

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

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

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

Investment Income — Interest income is recorded on the accrual basis and includes accretion of discounts and amortization of premiums.

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

Distributions to Shareholders — Distributions from net investment income for the funds are declared daily and distributed monthly. Distributions from net realized gains for the funds are declared and paid annually.

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

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

Intermediate-Term and Long-Term have elected to treat $785,227 and $905,983, respectively, of net capital losses incurred in the ten month period ended August 31, 1999, as having been incurred in the following fiscal year.

Futures Contracts — Each fund may buy and sell interest rate futures contracts relating to debt securities. Each fund may use futures transactions to maintain cash reserves while remaining fully invested, to facilitate trading, to reduce transaction costs, or to pursue higher investment returns when a futures contract is priced more attractively than its underlying security or index. One of the risks of entering into futures contracts may include the possibility that the changes in value of the contract may not correlate with the changes in value of the underlying securities. Upon entering into a futures contract, the funds are required to deposit either cash or securities in an amount equal to a certain percentage of the contract value (initial margin). Subsequent payments (variation margin) are made or received daily, in cash, by the funds. The variation margin is equal to the daily change in the contract value and is recorded as an unrealized gain or loss. The funds recognize a realized gain or loss when the contract is closed or expires. Net realized and unrealized gains or losses occurring during the holding period of futures contracts are a component of realized gain (loss) on investments and unrealized appreciation (depreciation) on investments, respectively. There were no open futures contracts at February 29, 2000.

Additional Information — Funds Distributor, Inc. (FDI) is a distributor of the trust. Certain officers of FDI are also officers of the trust.


2. Transactions with Related Parties

The trust has entered into a Management Agreement with American Century Investment Management, Inc. (ACIM), under which ACIM provides each fund with investment advisory and management services in exchange for a single, unified management fee. The Agreement provides that all expenses of the funds, except brokerage, taxes, portfolio insurance, interest, fees and expenses of the trustees who are not considered "interested persons" as defined in the 1940 Act (including counsel fees) and extraordinary expenses, will be paid by ACIM. The fee is calculated daily and paid monthly. It consists of an Investment Category Fee based on the average net assets of the funds in a specific fund's investment category and a Complex Fee based on the average net assets of all the funds managed by ACIM. The rates for the Investment Category Fee range from 0.1625% to 0.2800% and the rates for the Complex Fee range from 0.2900% to 0.3100%. For the six months ended February 29, 2000, the effective annual management fee was 0.51%, for Limited-Term, Intermediate-Term, and Long-Term.

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

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

4. Bank Loans

Background Information


Investment Philosophy and Policies

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

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

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

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

California Limited-Term Tax-Free seeks interest income exempt from both federal and California state income taxes. The fund invests primarily in California municipal securities and maintains a weighted average maturity of five years or less.

California Intermediate-Term Tax-Free seeks interest income exempt from both federal and California state income taxes. The fund invests primarily in California municipal securities and maintains a weighted average maturity of 5-10 years.

California Long-Term Tax-Free seeks interest income exempt from federal and California state income taxes. The fund invests primarily in California municipal securities and maintains a weighted average maturity of 10 years or more.

Comparative Indices

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

The Lehman Brothers 3-Year Municipal Bond Index is composed of more than 4,000 municipal bonds with maturities of 2-4 years. The average credit rating of the securities in the index is AA1/AA2. The index's average maturity is 3 years.

The Lehman Brothers 5-Year General Obligation (GO) Index is composed of more than 5,000 municipal bonds with maturities of 4-6 years. The average credit rating of the securities in the index is AA1/AA2. The index's average maturity is approximately 5 years.

The Lehman Brothers Long-Term Municipal Bond Index is composed of more than 2,800 municipal bonds with maturities greater than 22 years. The average credit rating of the securities in the index is AA2/AA3. The index's aver age maturity is approximately 27 years.

Credit Rating Guidelines

Credit ratings are issued by independent research companies such as Standard & Poor's and Moody's. They are based on an issuer's financial strength and ability to pay interest and principal in a timely manner.

Securities rated AAA, AA, A, or BBB are considered "investment-grade" securities, meaning they are relatively safe from default. Here are the most common credit ratings and their definitions:

It's important to note that credit ratings are subjective, reflecting the opinions of the rating agencies; they are not absolute standards of quality.

Fund Classifications

Please be aware that the fund's category may change over time. Therefore, it is important that you read a fund's prospectus or fund profile carefully before investing to ensure its objectives, policies, and risk potential are consistent with your needs.

Investment Objective

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

Risk

The classification of funds by risk category is based on quantitative historical measures as well as qualitative prospective measures. It is not intended to be a precise indicator of future risk or return levels. The degree of risk within each category can vary significantly, and some fund returns have historically been higher than more aggressive funds or lower than more conservative funds.

The investment objective may be based on the fund's objective as stated in its prospectus or fund profile, or the fund's categorization by independent rating organizations based on its management style.
The classification of funds by risk category is based on quantitative historical measures as well as qualitative prospective measures. It is not intended to be a precise indicator of future risk or return levels. The degree of risk within each category can vary significantly, and some fund returns have historically been higher than more aggressive funds or lower than more conservative funds. Please be aware that a fund's category may change over time. Therefore, it is important that you read a fund's prospectus or fund profile carefully before investing to ensure its objectives, policies and risk potential are consistent with your needs. For a definition of fund categories, see the Glossary.
*While listed within the Income investment objective, the Target funds do not pay current dividend income. Income dividends are distributed once a year in December. The Target funds are listed in all three risk categories due to the dramatic price volatility investors may experience during certain market conditions. If held to their target dates, however, they can offer a conservative, dependable way to invest for a specific time horizon.
Please call 1-800-345-2021 for a prospectus or profile on any American Century fund. These documents contain important information including charges and expenses, and you should read them carefully before you invest or send money.
