                               REPORT HIGHLIGHTS

MARKET PERSPECTIVE

* Municipal securities produced solid returns during the fiscal year as interest
  rates declined overall. Longer-term securities performed best.

* Relatively low municipal  issuance and strong demand helped support  municipal
  bond prices.

* Credit  spreads  fell to  historically  low levels  because of the increase in
  insured securities and stronger California municipal credit quality.

MUNICIPAL CREDIT REVIEW

* California's  economy  continued to expand during the fiscal year,  leading to
  further improvements in state and local municipal credit quality.

* Emanating  from the Bay Area,  growth has been  spreading  throughout  much of
  California, especially among the coastal areas of Southern California.

* We believe the favorable growth scenario currently in place will result in yet
  another upgrade of California's credit rating in the near future.

LIMITED-TERM TAX-FREE

* The Fund turned in a strong  performance  for the fiscal year ended August 31,
  1997.

* The fund performed well primarily because of our careful security selection.

* Another  factor  enhancing the fund's  returns was our  selective  addition of
  newly issued securities.

* Going forward, we will likely maintain the fund's slightly longer-than-average
  maturity compared with its peers.

INTERMEDIATE-TERM TAX-FREE

* The Fund turned in a favorable  performance  for the fiscal year ended  August
  31, 1997, reflecting improving economic conditions.

* Careful security selection helped to add to the fund's returns.

* Our outlook for municipal  securities is generally positive as inflation still
  appears under control.

* Going forward,  we will likely  maintain the fund's  conservative  positioning
  until market conditions seem to warrant a different stance.

LONG-TERM TAX-FREE

* The  fund's  returns  and  yields  exceeded  those of the  average  California
  long-term municipal fund for the fiscal year ended August 31, 1997.

* To enhance the fund's yield and return,  we were  underweighted  in bonds with
  coupons between 5.125% and 5.875% and overweighted in higher-yielding  premium
  bonds and lower-coupon discount and non-callable bonds.

* Going forward, we'll continue to manage the fund conservatively.  We'll likely
  adopt a contrarian strategy best suited to a range-bound market.

                              OUR MESSAGE TO YOU

              [photo of James E. Stowers III and James M. Benham]

    For the twelve months ended August 31, 1997,  municipal  bonds posted strong
returns as bond yields declined overall. Municipal bonds benefited from the fact
that issuance of new securities remained relatively low. In the following pages,
our municipal  investment team provides further details about the municipal bond
market and how your fund was managed during the period.

    During the summer, American Century held its largest proxy vote ever, asking
shareholders  to approve  measures to simplify  fund  management  and  eliminate
overlapping  funds.  Most notably,  shareholders  approved a unified fee for all
funds.  In the past,  many of our funds had both a  management  fee and separate
administrative  and transfer  agency  fees.  Under the new fee  structure,  fund
shareholders  pay one  annual  management  fee,  based on a  percentage  of fund
assets.

    We also made some important corporate changes. In June, Bill Lyons, American
Century's   chief   operating   officer,   became   president,   assuming   full
responsibility for the company's  day-to-day  operations.  With this change, Jim
Stowers,  Jr. and Jim Stowers III will be able to spend more time developing and
refining new  investment  technologies  and tools that build on and leverage the
proprietary  system they  pioneered  25 years ago. One of our goals is to ensure
that we continue to evolve and  innovate--building  the  investment  tools today
that will lead us and our investors to success in the next century.

    In July,  American Century agreed to enter into a business  partnership with
J.P.  Morgan & Co., Inc.,  one of the strongest and most respected  firms in the
financial  services  industry.  J.P.  Morgan will become a significant  minority
owner of American Century Companies, Inc. Through this partnership,  we see many
opportunities  to expand the range of  investment  choices and services we offer
you. A global financial services firm, J.P. Morgan has been in business for more
than 150 years, serving  institutions,  governments and individuals with complex
financial needs.

    Within  the  framework  of this  new  relationship,  American  Century  will
continue  to  operate as an  independent  company.  No  changes  in your  fund's
investment  managers,  policies  or fees are  anticipated  as a  result  of this
transaction.  American Century's corporate management team remains the same, and
the Stowers family will retain voting control of the company.

    In closing,  we want to reassure you that American Century remains committed
to serving your  investment  needs first and foremost.  Thank you for your trust
and confidence.

Sincerely,

/s/James E. Stowers III                  /s/James M. Benham
James E. Stowers III                     James M. Benham

    Municipal  securities  produced solid returns during the twelve months ended
August 31, 1997, as interest rates declined.  Longer-term securities,  which are
most sensitive to changes in interest rates and inflation,  performed  best. The
Lehman  Long-Term  Municipal Index returned 11.26% for the period;  in contrast,
the Lehman 3-Year Municipal Index returned 5.65%.

    Despite lower rates  overall,  municipal  yields  fluctuated  throughout the
period (see the accompanying graph). Yields rose and prices fell most sharply in
the first quarter of 1997, when it appeared rapid economic growth and wage gains
would spark inflation. To head-off potential inflation, the Federal Reserve (the
Fed)  raised  short-term  interest  rates in  March,  the first  increase  since
February 1995.

    Municipal  securities  began to rally (and  yields  fell) in May,  when U.S.
economic  growth slowed and it was clear that inflation  remained  tame.  Rising
worker  productivity  also helped bonds  because it suggests that wages can rise
without translating into higher prices.

    Demand from retail investors for municipal  securities was reasonably strong
during the period.  Property and casualty insurance companies in particular were
big buyers, especially early in the period.

    Municipal debt issuance is up so far in 1997 over 1996 levels,  but is still
low by historical  standards.  Total municipal debt issuance topped $126 billion
through August;  in contrast,  only $118 billion in muni debt was issued for all
of 1996.  The  combination of relatively  strong demand and low supply  compared
with prior years supported municipal prices throughout the period.

    Low supply in recent  years has caused a fight for market  share  among bond
insurers.  While  insurers used to insure  municipal  bonds down to an A rating,
they have recently begun to insure even BBB-rated bonds. As a result,  about 70%
of all municipal  debt issued in California  now comes to market  insured with a
AAA rating.

    This has helped boost credit quality generally by dramatically  reducing the
amount of securities issued at the lower investment grades. But it has increased
competition for a shrinking  supply of lower-rated,  higher-yielding  paper. The
net  effect  is that the  market  is paying  less and less  attention  to credit
quality in an attempt to grab yield.

    The scarcity of high-yielding  securities caused the difference in yield, or
"spread," between securities rated AAA and BBB paper to fall to historically low
levels (see the accompanying  graph). The strong growth of California's  economy
and tax revenues have also  contributed to this trend as credit quality improves
across the state (see page 4).

    California's  economy  continued  to improve  during  the fiscal  year ended
August 31, 1997.  The state's  ability to generate  strong job growth in various
sectors,  while  benefiting  from an improving  national  economy,  has been the
cornerstone  of  California's  impressive  economic  growth.  With  the  state's
workforce burgeoning,  the unemployment rate dropped to 6.2% by August 1997 (see
the  accompanying  graph),  down sharply  from the 7.1% figure  posted in August
1996.  Not only has  California's  employment  growth  continued  to exceed  the
national average,  but so have its income gains. Perhaps the largest contributor
to this favorable scenario has been strong growth in the high-technology sector,
which has helped  eliminate the negative  impact of the job losses caused by the
1990 recession.

    Another  factor  working in  California's  favor is its  exports,  which are
nearly equal those of the other 49 states combined.  Its gross product surpassed
the $1 trillion milestone in 1997--a landmark passed by the U.S. as a whole less
than 30 years ago. The state's  finances also continue to  improve--its  revenue
for the 1996-1997 fiscal year was approximately $300 million over budget.

    Anchoring the state's  strongest growth has been the San Francisco Bay Area,
led by the hub of the state's  thriving  high-technology  industry,  Santa Clara
County.  This growth trend has been  spreading  throughout  much of  California,
especially  among  the  coastal  areas of  Southern  California.  For  instance,
year-over-year  employment  growth in the Los Angeles  County area was 4%. Other
improving coastal areas include San Diego,  Long Beach and Orange County,  which
is benefiting from a thriving biotechnology  industry. The central valley areas,
such as Sacramento  and  Stanislaus  Counties,  are also  experiencing  improved
economic conditions.

    As a result of the stronger  economy,  both state and local municipal credit
quality have continued to improve.  Securities that benefited the most from this
trend were tax-based  securities such as COPs and  tax-allocation  bonds. On the
other hand,  electric  utility and  hospital  issues  suffered  under  increased
competition in their industries.

    Despite the currently  favorable  environment,  California  will likely face
some difficult choices in the coming years. Foremost among these concerns is the
likelihood  that capital needs will  increase for education and  transportation.
The state's infrastructure,  particularly its public school system, will require
additional funds to support its burgeoning population.  In addition,  California
housing  prices  have  continued  to rise along with the cost of living,  making
quality of life issues a greater concern for residents.

    Nevertheless,  our  outlook  for the  state's  credit  rating  remains  very
positive.  We believe the  favorable  growth  scenario  currently  in place will
result in yet another upgrade of California's credit rating in the near future.

    To help insure that the municipals chosen for the California funds match our
strict criteria, the five members of our municipal credit research team continue
to keep a close watch on these issues and other economic and legislative  trends
within the state.

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM?

    The fund turned in a strong performance for the fiscal year ended August 31,
1997. For the period,  the fund's 5.42% return was higher than the 5.12% average
return of the 10 "California Short-Intermediate Municipal Debt Funds" tracked by
Lipper  Analytical  Services.  (See the Total Returns table on the previous page
for other fund performance comparisons.)

WHY DID THE FUND PERFORM WELL AGAINST ITS PEERS?

    One reason was our careful security selection.  In early spring, we invested
nearly 6% of the  fund's  assets  in Puerto  Rico  municipal  securities.  These
securities have the unique  distinction of providing  double tax-free income for
investors  in all 50 states  and  provide  a viable  alternative  to  California
municipals  when  conditions  warrant.  Since  we  felt  many  of the  available
California municipals were overpriced,  we chose more attractively valued Puerto
Rico securities.  That choice paid off  handsomely--these  securities  performed
better than we expected, boosting the fund's returns.

                       CALIFORNIA LIMITED-TERM TAX-FREE

    Another  factor  enhancing  the  fund's  returns  was our  ability  to buy a
larger-than-usual  amount of newly  issued  securities  rather than ones already
available in the marketplace. A large influx of investment capital into the fund
caused its assets to grow nearly 8% over the last six months. Using these funds,
we selectively added new issues we felt were attractively valued.

THE FUND IS NOW HOLDING SOME BONDS RATED BBB. DID YOU USE SOME OF THE INCOMING
CASH TO PURCHASE THESE SECURITIES?

    Yes. Rather than use the money to purchase  municipals  rated AA, which were
hard to find at attractive  prices,  we invested the cash inflows in lower-rated
municipals.

    The most  attractively  priced municipals we found were primarily rated BBB.
The introduction of these  securities,  many of which were new issues,  into the
fund's  portfolio  shifted  its  credit  structure.  The net result was that the
percentage of municipals rated AAA remained  unchanged,  while the percentage of
AA municipals  decreased  and the  percentage of BBB  securities  increased.  We
believe that this slight "credit barbell," where securities are held at the ends
of the fund's  credit  spectrum,  will  continue to perform  well in the current
market environment.

WAS THE MUNICIPAL CREDIT RESEARCH TEAM INSTRUMENTAL IN FINDING THESE SECURITIES

    Yes. The team  continued to make  accurate  assessments  of specific  credit
situations  and helped us steer clear of many  overpriced  issues.  To find such
hidden values, our credit research team analyzes detailed financial information,
talks directly with municipal  officials and frequently travels around the state
for  on-site  visits and tours.  California  is a complex,  dynamic  state,  and
thorough  research is an integral  part of the security  selection  process.  We
therefore  work  closely  with  our  municipal  credit  research  staff  to find
securities that we feel will enhance the fund's performance.

HOW DID YOU MANAGE THE FUND'S AVERAGE MATURITY DURING THE PERIOD?

    We made only minor adjustments during the first half of the period, adopting
a neutral  position  relative  to the fund's  peers.  Due to  uncertainty  about
interest rates and the possibility of further Fed rate  increases,  we felt this
conservative  stance  was  warranted.   By  the  time  June  arrived,   however,
uncertainty in the marketplace  quickly dissipated as inflation remained benign.
With the market  rally  gaining  momentum,  we  lengthened  the  fund's  average
maturity  slightly to take  advantage of rising bond  prices.  By the end of the
period, the fund's average maturity was a bit longer than that of its peers.

DID YOU MAKE ANY CHANGES TO THE FUND'S STRUCTURE DURING THE FISCAL YEAR?

    Yes. Structural  adjustments remain another important tool we use to enhance
the fund's  returns.  Early in the fiscal year,  the fund was structured to take
advantage  of the  steep  municipal  yield  curve  environment,  with a  heavier
weighting in securities maturing in one year and 5-8 years and an underweighting
in intermediate-term securities.

    This  "barbell"  structure  tends to perform best when the yield curve moves
from steep to flat,  as it did during the latter part of the  period.  While the
yield curve  continued to flatten in recent months,  we will likely maintain the
fund's barbelled position until rates stabilize.  At that time, we will reassess
the fund's position and make any appropriate adjustments.

WHAT IS THE OUTLOOK FOR MUNICIPAL SECURITIES GOING FORWARD?

    Our outlook for municipals is generally  positive.  Inflation  remains tame,
having  risen at a mere 1.6% annual rate during the first eight  months of 1997.
"Real"  interest rates (nominal  interest rates minus  inflation) are relatively
high,  which should  inhibit  inflation and economic  growth going  forward.  In
addition,  strong productivity gains should continue to offset wage gains in the
near  future.  As a result,  we think the Federal  Reserve can  continue to hold
rates steady.

    We also  expect bond  insurers  to  continue to be active in the  California
municipal market,  increasing credit quality and generally driving yield spreads
lower. That means credit spreads could continue to narrow.

    Nevertheless,  municipals may continue to fluctuate,  particularly if we get
signs of  stronger-than-expected  economic growth.  For municipal  securities to
rally further, it would likely take sharply slower economic growth or a dramatic
drop in inflation.

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

    For  the  near  term,   we  will  likely   maintain   the  fund's   slightly
longer-than-average  maturity  compared with its peers. If the economy continues
to slow as we expect it will,  this position  should  enhance the fund's returns
and add to its  income  stream.  Keep in mind that in a fund  such as this,  the
majority of the fund's  returns  come from  current  income  rather than capital
appreciation. As such, we will continue to work closely with our credit research
staff in search of securities offering attractive yields at reasonable prices.

    We will also closely monitor where municipals are within their current price
range.  Our emphasis in this strategy will be to take advantage of opportunities
to buy when we feel  prices are low within the range and sell when  prices  seem
high.

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM?

    The fund  performed  favorably  for the fiscal year ended  August 31,  1997,
reflecting  improving  economic  conditions.  For the period,  the fund's  7.39%
return was slightly  higher than the 7.29% average  return of the 29 "California
Intermediate  Municipal Debt Funds" tracked by Lipper Analytical Services.  (See
the  Total  Returns  table on the  previous  page  for  other  fund  performance
comparisons.)

HOW WAS THE FUND POSITIONED DURING THE FISCAL YEAR?

    Uncertainty  concerning  interest rates and potential inflation convinced us
to take a conservative  stance early in 1997,  especially  between  February and
April.  During that time,  short- and  intermediate-term  municipal  prices fell
sharply  amid  investor  concern  that the Federal  Reserve  would embark upon a
series  of  short-term  interest  rate  hikes.  In  order to  limit  the  fund's
vulnerability to this  possibility,  we kept its duration neutral with its peers
at around 5.4 years.

    Toward the end of April,  when  investors  began to feel that  inflation was
under control,  intermediate municipal prices rebounded.  Securities maturing in
four to seven years performed particularly well thanks to a surge in demand from
investors. We used the rally as an opportunity to sell many of these issues at a
healthy profit.

    We replaced  these  securities  with  issues  maturing in 9-15 years that we
believed  were  more  attractively  priced  and  offered  greater   appreciation
potential.  These  securities  became  especially  attractive  because  of their
increased supply,  which put downward pressure on their prices. Since demand for
municipals in this area also remained soft, the  combination  worked in an ideal
way to make the  securities  available at attractive  values.  After  purchasing
these longer-intermediate  municipals, the fund's duration lengthened to as much
as 5.6 years.

    As the rally continued, the longer-maturity securities we purchased began to
pay off.  Deciding  to shorten  the fund's  duration,  we began  unwinding  this
position by selling the  securities at a profit.  By the end of the period,  the
fund's duration was roughly neutral to its peers.

WHAT PART DID THE MUNICIPAL CREDIT RESEARCH TEAM PLAY IN FINDING THESE
SECURITIES?

    The  team  continued  to  make  accurate   assessments  of  specific  credit
situations  and helped us steer clear of many  overpriced  issues.  To find such
hidden values, our credit research team analyzes detailed financial information,
talks directly with municipal  officials and frequently travels around the state
for  on-site  visits and tours.  California  is a complex,  dynamic  state,  and
thorough  research is an integral  part of the security  selection  process.  We
therefore  work  closely  with  our  municipal  credit  research  staff  to find
securities that we feel will enhance the fund's performance.

WHY DID YOU HOLD SOME TREASURY PUT OPTIONS DURING THE PERIOD?

    We bought  the  Treasury  put  options  for  added  protection  against  the
possibility  of a bond market  selloff.  (A put option allows the  bondholder to
sell a security at a  predetermined  price on a specified  date.) By hedging the
fund  with   Treasury   puts,   we  were  able  to  hold  more   longer-maturity
intermediate-term municipals than we otherwise would have felt comfortable with

WHAT IS THE OUTLOOK FOR CALIFORNIA MUNICIPALS GOING FORWARD?

    Our outlook for the state's  municipal  securities  is  generally  positive.
Inflation remains tame, having risen at a mere 1.6% annual rate during the first
eight  months of 1997.  "Real"  interest  rates  (nominal  interest  rates minus
inflation) are  relatively  high,  which should  inhibit  inflation and economic
growth going forward. In addition,  strong productivity gains should continue to
offset wage gains in the near future.  As a result, we think the Federal Reserve
can continue to hold rates steady.

    We also  expect bond  insurers  to  continue to be active in the  California
municipal  market,   increasing  credit  quality  and  generally  driving  yield
spreads--the   interest  rate  difference   between  higher-  and  lower-quality
municipals--lower.

    Nevertheless,  municipals may continue to fluctuate,  particularly if we get
signs of  stronger-than-expected  economic growth.  For municipal  securities to
rally further, it would likely take sharply slower economic growth or a dramatic
drop in inflation.

GIVEN THIS SITUATION, WHAT ARE YOUR PLANS FOR THE FUND OVER THE NEXT SIX MONTHS

    For the near term, we plan on maintaining the fund's neutral duration. Since
interest  rates are currently  very low,  refundings  may start to rise.  When a
municipality  refunds old debt,  it retires the  outstanding  security  that was
issued  when  rates  were  high  and  replaces  the  issue  with a newer  one at
prevailing--typically  lower--interest rates. This scenario should be beneficial
for the fund because there are many premium bonds in its portfolio that might be
refunded.

    We will also closely monitor where municipals are within their current price
range.  Our emphasis in this strategy will be to take advantage of opportunities
to buy when we feel  prices are low within the range and sell when  prices  seem
high.

                         CALIFORNIA LONG-TERM TAX-FREE

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM?

    The fund  performed  very well  relative  to its peers.  For the fiscal year
ended August 31, 1997, the fund returned 9.70%,  compared with the 8.98% average
return of the 101 "California Municipal Debt Funds" tracked by Lipper Analytical
Services. The fund's longer-term returns are even more impressive.  For example,
the fund's three- and five-year  returns place it in the top quarter of its peer
group.  (See the  Total  Returns  table on the  previous  page  for  other  fund
performance comparisons.)

    The fund also produced a higher level of current  income than its peer group
average.  As of August 31, the fund's 30-day SEC yield was 4.64%,  compared with
the 4.23%  average  yield of the fund's  peers.  One  reason  we've been able to
produce such strong yields and returns is that the fund's expenses are below the
peer group average.  All else being equal, lower expenses mean higher yields and
returns for fund shareholders.

HOW WAS THE FUND POSITIONED DURING THE PERIOD?

    We lengthened  the fund's  duration  slightly in the second  quarter to take
advantage  of the  decline  in  interest  rates.  (Duration  is a measure of the
portfolio's  sensitivity to changes in rates.) The longer a fund's duration, the
more its share price  tends to rise when rates  decline.  In  general,  we use a
conservative  approach to managing the fund's  duration,  keeping it in a narrow
range around eight years.  Instead,  we look to add value to the fund  primarily
through careful credit analysis and security selection.

CAN YOU GIVE AN EXAMPLE OF HOW YOU MANAGED THE FUND FOR A  COMBINATION  OF YIELD
AND RETURN?

    Sure. We tried to enhance the fund's yield and return by carefully  managing
the fund's coupon  structure.  For example,  many of the  outstanding  long-term
municipal bonds have coupons between 5.125% and 5.875%.  We put less emphasis on
these  securities,  buying  them only if there was a  compelling  credit  story.
Instead, we tried to maintain a "barbell" coupon structure, with the majority of
the fund's assets in higher-coupon  premium bonds and lower-coupon  discount and
non-callable bonds.

    The premium bonds were intended to shorten duration,  while the lower-coupon
discount bonds helped the fund's returns  because their prices tend to rise more
rapidly than premium bonds when rates fall.

WHY DOES THE FUND HAVE SUCH A SMALL HOLDING OF BONDS RATED BBB?

    With  credit  spreads at  historic  lows (see page 4), we don't  think we're
being properly  compensated  for the additional  credit risk of holding most BBB
securities.  In the past, BBB-rated bonds might offer yields 100 basis points or
more above AAA bonds.  Today,  that risk premium can be as low as 20 or 30 basis
points.  As a  result,  we're  very  selective  when  adding  these  lower-rated
securities to the fund. Nevertheless,  our ability to buy the entire spectrum of
investment-grade  securities has helped the fund's  performance.  Though we hold
only about 5% of the fund in these lower-rated  bonds,  we've carefully selected
securities  we think  have a good  chance  to  appreciate  in  value as  spreads
continue to tighten.

HOW HAS THE DEREGULATION OF THE ELECTRIC UTILITIES INDUSTRY AFFECTED THE FUND?

    Deregulation has changed the way we look at this sector.  In general,  we're
avoiding new municipal  electric  utility debt because we're uncertain how these
entities will perform when faced with competition.  But the change has been good
for debt issued  before the  reforms  were  enacted.  That's  because  municipal
utilities have been refunding much of that debt to get it off their books.  In a
refunding,  the issuer  establishes  an escrow  account of Treasury  securities.
That's great for the fund because we continue to draw current tax-free income on
an investment secured by Treasurys.

YOU HELD SOME TREASURY PUT OPTIONS DURING THE PERIOD. WHY?

    We bought Treasury put options as a form of insurance  against a bond market
decline.  (A  put  option  allows  the  bondholder  to  sell  a  security  at  a
pre-determined  price on a specified  date.) Hedging the fund with Treasury puts
allowed us to hold more long-term  municipal  securities than we otherwise would
have felt comfortable with.

WHAT IS YOUR  OUTLOOK  FOR THE  CALIFORNIA  MUNICIPAL  MARKET  OVER THE NEXT SIX
MONTHS?

    Our outlook for municipals is generally  positive.  Inflation  remains tame,
having risen by just 2.2% for the twelve  months  ended August 31, 1997.  "Real"
interest rates (nominal  interest rates minus the inflation rate) are relatively
high,  which should  inhibit  inflation and economic  growth going  forward.  In
addition,  strong productivity gains should continue to offset wage gains in the
near  future.  As a result,  we think the Federal  Reserve can  continue to hold
rates steady.

    We also  expect bond  insurers  to  continue to be active in the  California
municipal  market,  increasing  credit  quality and driving  down yield  spreads
generally.

    Nevertheless,  municipal securities may continue to fluctuate,  particularly
if we get signs of  stronger-than-expected  economic  growth.  For municipals to
rally further, it would likely take sharply slower economic growth or a dramatic
drop in inflation.

WITH THIS OUTLOOK IN MIND, WHAT ARE YOUR PLANS FOR THE FUND GOING FORWARD?

    We'll likely keep the fund's duration slightly longer than neutral, which is
around eight years.  That should help the fund's  performance if economic growth
and inflation remain tame. We'll also adopt a contrarian  strategy--buying  when
others sell and selling when they buy.  While we can't  guarantee  this strategy
will be successful, we believe it may allow us to sell at peaks and buy at dips.
We will also continue to work closely with our credit  research team to look for
attractively valued securities.

NOTES TO SCHEDULE OF INVESTMENTS

AMBAC = AMBAC Indemnity Corporation

FGIC = Financial Guaranty Insurance Company

FSA = Financial Security Assurance

GO = General Obligation

MBIA = MBIA Insurance Corp.

VRDN   = Variable Rate Demand Note. Interest reset date is indicated and used in
       calculating  the  weighted  average  portfolio  maturity.  Rate  shown is
       effective August 31, 1997.

(1) These  securities are zero-coupon  municipal bonds. The yield to maturity at
    August 31, 1997 is indicated  instead of a stated  coupon rate.  Zero-coupon
    securities  are  purchased  at a  substantial  discount  from their value at
    maturity.

(2) Escrowed in U.S. Government Securities.

(3) Inverse floaters have interest rates which move inversely to market interest
    rates.  Inverse  floaters  typically  have  durations  which are longer than
    long-term  bonds,  which  may cause  their  value to be more  volatile  than
    long-term bonds when interest rates change.

32      STATEMENTS OF CHANGES IN NET ASSETS    AMERICAN CENTURY INVESTMENTS


                         NOTES TO FINANCIAL STATEMENTS

AUGUST 31, 1997

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION--American  Century California Tax-Free and Municipal Funds (the
Trust) is  registered  under the  Investment  Company Act of 1940 as an open-end
management investment company. American Century - Benham California Limited-Term
Tax-Free   Fund   (Limited-Term),   American   Century   -   Benham   California
Intermediate-Term  Tax-Free Fund  (Intermediate-Term)  , and American  Century -
Benham California Long-Term Tax-Free Fund (Long-Term) (the "Funds") are three of
the seven funds  issued by the Trust.  Each Fund is  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,  related  to  the  Funds,  are  in
accordance with accounting policies generally accepted in the investment company
industry.

    SECURITY  VALUATIONS--Securities are valued through valuations obtained from
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 on the date
purchased  or  sold.  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  amortization  of premiums and  discounts.  Premium and original  issue
discount are amortized  daily using the effective  interest rate method.  Market
discount is recognized as income upon the sale or maturity of the security.

    INCOME TAX  STATUS--It is the Funds' policy to distribute all net investment
income and net realized capital 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 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.

    At August 31, 1997,  accumulated  net realized  capital loss  carryovers  of
$833,657 for  Limited-Term  (expiring  2003 through  2004) may be used to offset
future taxable gains. Distributions from net investment income for the Funds for
the year ended August 31, 1997,  are exempt from  federal and  California  state
taxes.

    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  are due to differences in the
recognition  of  income  and  expense  items  for  financial  statement  and tax
purposes.

    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 Fund  recognizes a realized gain or
loss when the contract is closed or expires.  Net realized and unrealized  gains

    USE OF ESTIMATES--  The  preparation  of financial  statements in conformity
with  generally  accepted  accounting  principles  requires  management  to make
estimates  and  assumptions  that  affect  the  reported  amounts  of assets and
liabilities  and disclosure of contingent  assets and liabilities at the date of
the financial  statements and the reported amounts of increases and decreases in
net assets from operations  during the period.  Actual results could differ from
these estimates.

2. TRANSACTIONS WITH RELATED PARTIES

    The  shareholders of the Fund approved a new management  agreement with ACIM
on July 30,  1997,  effective  August 1, 1997,  which  replaced  the  previously
existing contracts between the Funds and Benham Management  Corporation and ACSC
for advisory,  administrative and transfer agency services. Under the agreement,
ACIM  provides all services  required by the Funds in exchange for one "unified"
management  fee.  The annual rate at which this fee is  assessed  is  determined
monthly in a two-step  process:  First,  a fee rate  schedule  is applied to the
assets of all of the funds in the Fund's  investment  category which are managed
by ACIM (the  "Investment  Category Fee"). The overall  investment  objective of
each Fund determines its Investment  Category.  The three investment  categories
are: the Money Market Fund Category,  the Bond Fund Category and the Equity Fund
Category. Limited-Term, Intermediate-Term and Long-Term are included in the Bond
Fund Category.  Second, a separate fee rate schedule is applied to the assets of
all of the funds managed by ACIM (the "Complex  Fee").  The Investment  Category
Fee and the Complex Fee are then added to determine the unified  management  fee
rate.  The  management  fee is paid  monthly by each Fund  based on each  Fund's
aggregate  average daily net assets during the previous month  multiplied by the
monthly management fee rate. The annualized  Investment Category Fee schedule is
as follows:

      0.2800% of the first $1 billion  
      0.2280% of the next $1 billion 
      0.1980% of the next $3 billion 
      0.1780% of the next $5 billion 
      0.1650% of the next $15 billion 
      0.1630% of the next $25 billion
      0.1625% of the average daily net assets over $50 billion

The annualized Complex Fee schedule (for all Funds) is as follows:

      0.3100% of the first $2.5 billion 
      0.3000% of the next $7.5 billion 
      0.2985% of the next $15 billion  
      0.2970% of the next $25 billion  
      0.2960% of the next $50 billion 
      0.2950% of the next $100 billion 
      0.2940% of the next $100 billion  
      0.2930% of the next $200 billion 
      0.2920% of the next $250 billion
      0.2910% of the next $500 billion
      0.2900% of the average daily net assets over $1,250 billion

  The following total expenses, incurred under the new management agreement, are
included in Investment Advisory Fees in the Statements of Operations:

                        LIMITED-TERM          INTERMEDIATE-TERM       LONG-TERM

  Total  expenses  and the ratio of  operating  expenses  to average net assets,
under the previous agreement,  for the eleven months ended July 31, 1997 were as
follows:

                        LIMITED-TERM          INTERMEDIATE-TERM       LONG-TERM

including the schedules of investment  securities,  of American Century - Benham
California  Limited-Term  Tax-Free Fund,  American  Century - Benham  California
Intermediate-Term  Tax-Free  Fund,  and  American  Century  - Benham  California
Long-Term  Tax-Free  Fund,  (three  of the  series  issued by  American  Century
California  Tax-Free and Municipal Funds) (the Funds) as of August 31, 1997, and
the related  statements of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period  then  ended,  and
the financial  highlights  for each of the periods  presented.  These  financial
statements  and  financial  highlights  are  the  responsibility  of the  Funds'
management.  Our  responsibility  is to express  an  opinion on these  financial
statements and financial highlights based on our audits.

    We conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
August 31, 1997 by correspondence  with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

    In our  opinion,  the  financial  statements  and the  financial  highlights
referred to above  present  fairly,  in all  material  respects,  the  financial
position of the Funds as of August 31,  1997,  the results of their  operations,
the  changes in their net assets and the  financial  highlights  for the periods
indicated above in conformity with generally accepted accounting principles.

                                   GLOSSARY

RETURNS

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

* AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations  in a fund's  return;  they are not the same as  fiscal  year-by-year
results.  For  fiscal  year-by-year  returns,  please  refer  to the  "Financial
Highlights" on pages 36-38.

YIELDS

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

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

BOND PORTFOLIO STRUCTURES

* BARBELL  STRUCTURE--a  structure  that  overweights  a portfolio in short- and
long-term  securities  and  underweights   intermediate-term   securities.  This
structure  tends to perform best when  short-term  rates are rising  faster than
long-term rates, or long-term rates are falling faster than short-term rates.

* LADDER  STRUCTURE--a  balanced structure that staggers bond maturities so they
occur at regular  intervals.  This structure tends to perform best when interest
rates are relatively stable.

INVESTMENT TERMS

* BASIS POINT--one one-hundredth of a percentage point (or 0.01%).

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

STATISTICAL TERMINOLOGY

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

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

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

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

TYPES OF MUNICIPAL SECURITIES

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

* GO  BONDS--general  obligation  securities  backed by the taxing  power of the
issuer.

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

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

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

                              OUR MESSAGE TO YOU

              [photo of James E. Stowers III and James M. Benham]

    For the twelve months ended August 31, 1997,  municipal  bonds posted strong
returns as bond yields declined overall. Municipal bonds benefited from the fact
that issuance of new securities remained relatively low. In the following pages,
our municipal  investment team provides further details about the municipal bond
market and how your fund was managed during the period.

    During the summer, American Century held its largest proxy vote ever, asking
shareholders  to approve  measures to simplify  fund  management  and  eliminate
overlapping  funds.  Most notably,  shareholders  approved a unified fee for all
funds.  In the past,  many of our funds had both a  management  fee and separate
administrative  and transfer  agency  fees.  Under the new fee  structure,  fund
shareholders  pay one  annual  management  fee,  based on a  percentage  of fund
assets.

    We also made some important corporate changes. In June, Bill Lyons, American
Century's   chief   operating   officer,   became   president,   assuming   full
responsibility for the company's  day-to-day  operations.  With this change, Jim
Stowers,  Jr. and Jim Stowers III will be able to spend more time developing and
refining new  investment  technologies  and tools that build on and leverage the
proprietary  system they  pioneered  25 years ago. One of our goals is to ensure
that we continue to evolve and  innovate--building  the  investment  tools today
that will lead us and our investors to success in the next century.

    In July,  American Century agreed to enter into a business  partnership with
J.P.  Morgan & Co., Inc.,  one of the strongest and most respected  firms in the
financial  services  industry.  J.P.  Morgan will become a significant  minority
owner of American Century Companies, Inc. Through this partnership,  we see many
opportunities  to expand the range of  investment  choices and services we offer
you. A global financial services firm, J.P. Morgan has been in business for more
than 150 years, serving  institutions,  governments and individuals with complex
financial needs.

    Within  the  framework  of this  new  relationship,  American  Century  will
continue  to  operate as an  independent  company.  No  changes  in your  fund's
investment  managers,  policies  or fees are  anticipated  as a  result  of this
transaction.  American Century's corporate management team remains the same, and
the Stowers family will retain voting control of the company.

    In closing,  we want to reassure you that American Century remains committed
to serving your  investment  needs first and foremost.  Thank you for your trust
and confidence.

Sincerely,

/s/James E. Stowers III                  /s/James M. Benham

ANNUAL REPORT                                    OUR MESSAGE TO YOU       1


                               REPORT HIGHLIGHTS

MARKET PERSPECTIVE

*   Municipal securities produced solid returns during the year ended August 31,
    1997, as interest rates declined overall.

*   Municipals  rallied  sharply in the second  quarter  after it was clear that
    economic growth had moderated and inflation remained tame.

*   Relatively low municipal issuance and strong demand helped support municipal
    bond prices.

*   About 70% of all California  municipal bonds now come to market insured with
    a AAA  rating.  That  dramatically  reduced  the supply of  higher-yielding,
    lower-quality paper.

*   Credit  spreads--or  the  difference in yield  between AAA- and  lower-rated
    debt--fell  to  historically  low levels  because of the increase in insured
    securities and stronger California municipal credit quality.

MUNICIPAL CREDIT REVIEW

*   California's  economy continued to expand during the fiscal year, leading to
    further improvements in state and local municipal credit quality.

*   Emanating from the Bay Area,  growth has been spreading  throughout  much of
    California, particularly among the coastal areas of Southern California.

*   We believe the favorable  growth scenario  currently in place will result in
    yet another upgrade of California's credit rating in the near future.

TAX-FREE MONEY MARKET

*   The fund outperformed the average  California money market fund for the year
    ended August 31, 1997.

*   Because of changing  economic  conditions  and low supply among  longer-term
    municipal money market securities,  we shortened the fund's average maturity
    from 40 days to around 20 days  during the first  nine  months of the fiscal
    year.

*   We lengthened the fund's  average  maturity back to 40 days in June and July
    as one-year municipal note yields became more attractive.

*   Going  forward,  we plan to extend  the  fund's  average  maturity  further,
    possibly as high as 70 days, in the coming months.

*   We also  intend to put  further  limits on the fund's  exposure  to Japanese
    banks,  which provide credit  backing for many  California  municipal  money
    market securities.

MUNICIPAL MONEY MARKET

*   The fund outperformed the average  California money market fund for the year
    ended August 31, 1997.

*   Because of changing  economic  conditions  and low supply among  longer-term
    municipal money market securities,  we shortened the fund's average maturity
    from 40 days to around 20 days during the first  eight  months of the fiscal
    year.

*   We lengthened the fund's  average  maturity back to 40 days in June and July
    as one-year municipal note yields became more attractive.

2      REPORT HIGHLIGHTS                      AMERICAN CENTURY INVESTMENTS


                               REPORT HIGHLIGHTS

*   More than 75% of the fund's  assets were  invested  in AMT paper  (municipal
    securities that pay income subject to the federal  alternative minimum tax),
    higher than the 60% the fund typically holds.

*   Going  forward,  we plan to extend  the  fund's  average  maturity  further,
    possibly as high as 70 days, in the coming months.

*   We also  intend to put  further  limits on the fund's  exposure  to Japanese
    banks,  which provide credit  backing for many  California  municipal  money
    market securities.

HIGH-YIELD MUNICIPAL

*   The fund  continued to perform very well  compared with its peers during the
    fiscal year ended August 31, 1997.

*   One of the reasons the fund  performed so well was our thorough  approach to
    security selection.

*   Our municipal  credit research team continued to provide a vital link to the
    fund's success.

*   Going  forward,  we will likely  maintain the fund's  conservative  duration
    positioning and credit barbell structure.

INSURED TAX-FREE

*   The fund outperformed the average California insured municipal debt fund for
    the year ended August 31, 1997.

*   The fund's 4.55% 30-day  SEC-yield  far exceeded the 3.88%  average yield of
    its peers. Our  lower-than-average  expenses and careful security  selection
    account for the fund's strong performance.

*   To enhance the fund's yield and return, we were  underweighted in bonds with
    coupons between 5.125% and 5.875% and overweighted in higher-coupon  premium
    bonds and lower-coupon and non-callable discount bonds.

*   We used Treasury put options  during the period as insurance  against a bond
    market  decline.  Using  Treasury  puts allowed us to hold more  longer-term
    municipal securities.

*   Our outlook  for the  California  municipal  market is  generally  positive,
    though we think yields could continue to fluctuate.

*   Going forward, we'll continue to manage the fund's duration  conservatively.
    We'll  likely  adopt a  contrarian  strategy  best  suited to a  range-bound
    market.

    Municipal  securities  produced solid returns during the twelve months ended
August 31, 1997, as interest rates declined.  Longer-term securities,  which are
most sensitive to changes in interest rates and inflation,  performed  best. The
Lehman  Long-Term  Municipal Index returned 11.26% for the period;  in contrast,
the Lehman 3-Year Municipal Index returned 5.65%.

    Despite lower rates  overall,  municipal  yields  fluctuated  throughout the
period (see the accompanying graph). Yields rose and prices fell most sharply in
the first quarter of 1997, when it appeared rapid economic growth and wage gains
would spark  inflation.  To head off potential  inflation,  the Federal  Reserve
raised  short-term  interest  rates in March,  the first increase since February
1995.

    Municipal securities began to rally in May, when U.S. economic growth slowed
and it was clear that inflation  remained tame. Rising worker  productivity also
helped bonds  because it suggests that wages can rise without  translating  into
higher prices.

    Retail-investor demand for municipal securities was reasonably strong during
the period.  Property and casualty  insurance  companies in particular  were big
buyers, especially early in the period.

    Municipal debt issuance is up so far in 1997 over 1996 levels,  but is still
low by historical  standards.  Total municipal debt issuance topped $126 billion
through August; in contrast,  only $118 billion in municipal debt was issued for
all of 1996. The combination of relatively strong demand and low supply compared
with prior years supported municipal prices throughout the period.

    Low supply in recent  years has caused a fight for market  share  among bond
insurers.  While  insurers used to insure  municipal  bonds down to an A rating,
they have recently begun to insure even BBB-rated bonds. As a result,  about 70%
of all municipal  debt issued in California  now comes to market  insured with a
AAA rating.

    This has helped boost credit quality generally by dramatically  reducing the
amount of  securities  issued at the lower  investment  grades.  But it has also
increased  competition for a shrinking  supply of  lower-rated,  higher-yielding
paper.  The net effect is that the market is paying less and less  attention  to
credit quality in an attempt to grab yield.

    The scarcity of high-yielding  securities caused the difference in yield, or
"spread,"  between  securities  rated  AAA and BBB to fall to  historically  low
levels (see the accompanying  graph). The strong growth of California's  economy
and tax revenues has also  contributed to this trend as credit quality  improves
across the state (see page 5).

    California's  economy  continued  to improve  during  the fiscal  year ended
August 31, 1997.  The state's  ability to generate  strong job growth in various
sectors,  while  benefiting  from an improving  national  economy,  has been the
cornerstone  of  California's  impressive  economic  growth.  With  the  state's
workforce burgeoning,  the unemployment rate dropped to 6.2% by August 1997 (see
the  accompanying  graph),  down sharply  from the 7.1% figure  posted in August
1996.

    Not only has California's employment growth continued to exceed the national
average,  but so have its income gains.  Perhaps the largest contributor to this
favorable scenario has been strong growth in the high-technology  sector,  which
has helped  eliminate  the negative  impact of the job losses caused by the 1990
recession.

    Another  factor  working in  California's  favor is its  exports,  which are
nearly equal those of the other 49 states combined.  Its gross product surpassed
the $1 trillion milestone in 1997--a landmark passed by the U.S. as a whole less
than 30 years ago. The state's  finances also continued to improve--its  revenue
for the 1996-1997 fiscal year was approximately $300 million over budget.

    Anchoring the state's  strongest growth has been the San Francisco Bay Area,
led by the hub of the state's  thriving  high-technology  industry,  Santa Clara
County.  This growth trend has been  spreading  throughout  much of  California,
especially  among  the  coastal  areas of  Southern  California.  For  instance,
year-over-year employment growth in the L.A. County area was 4%. Other improving
coastal  areas  include  San  Diego,  Long  Beach and  Orange  County,  which is
benefiting  from a thriving  biotechnology  industry.  The central valley areas,
such as Sacramento  and  Stanislaus  Counties,  are also  experiencing  improved
economic conditions.

    As a result of the stronger  economy,  both state and local municipal credit
quality have continued to improve.  Securities that benefited the most from this
trend were tax-based  securities such as COPs and  tax-allocation  bonds. On the
other hand,  electric  utility and  hospital  issues  suffered  under  increased
competition in their industries.

    Despite the currently  favorable  environment,  California  will likely face
some difficult choices in the coming years. Foremost among these concerns is the
likelihood  that capital needs will  increase for education and  transportation.
The state's infrastructure,  particularly its public school system, will require
additional  funds to support its growing  population.  In  addition,  California
housing  prices  have  continued  to rise along with the cost of living,  making
quality of life issues a greater concern for residents.

    Nevertheless,  our  outlook  for the  state's  credit  rating  remains  very
positive.  We believe the  favorable  growth  scenario  currently  in place will
result in yet another upgrade of California's credit rating in the near future.

    To help ensure that the municipals chosen for the California funds match our
strict criteria, the five members of our municipal credit research team continue
to keep a close watch on these issues and other economic and legislative  trends
within the state.

6      CALIFORNIA TAX-FREE MONEY MARKET       AMERICAN CENTURY INVESTMENTS


                       CALIFORNIA TAX-FREE MONEY MARKET

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM DURING THE FISCAL YEAR?

    The fund  continued to provide a higher level of tax-exempt  income than the
average California money market fund. For the fiscal year ended August 31, 1997,
the fund had a total return of 3.17%,  compared with the 2.96% average return of
the 54 "California  Tax-Exempt Money Market Funds" tracked by Lipper  Analytical
Services.  (See the Total  Returns  table on the  previous  page for other  fund
performance comparisons.)

HOW DID THE FUND'S POSITIONING CHANGE DURING THE FISCAL YEAR?

    The fund's average maturity  shortened  gradually from around 40 days at the
beginning of the period to less than 20 days by mid-April. This shift was partly
driven by our  expectations  for a  short-term  interest  rate  increase  by the
Federal  Reserve--which  occured in March--but  it also  reflected a shortage of
one-year California municipal securities.  The limited supply depressed one-year
municipal yields; the few attractive  one-year notes we found failed to meet our
strict credit standards.

    In June and July, when most California  municipalities issue one-year notes,
we  extended  the fund's  average  maturity  back out to about 40 days.  We took
advantage of the seasonal  supply by purchasing  several  notes with  attractive
yields.  We would have liked to extend the fund's maturity even further,  but we
were  leery of  buying  too many  securities  with  the  same  6/30/98  maturity
date--the end of the fiscal year for most California municipalities.

ALTHOUGH THE FED RAISED SHORT-TERM RATES IN MARCH, THE FUND'S YIELD IS VIRTUALLY
THE SAME AS IT WAS A YEAR AGO. WHY?

    The Fed's  interest rate changes tend to have less of an impact on municipal
money market  yields than on taxable money market  yields.  The Fed raised rates
from 5.25% to only 5.50%,  and such a small increase  typically has a negligible
effect on municipal money market rates.

    Supply and demand factors have the biggest impact on municipal  money market
rates, and that's why yields haven't changed much over the past year.

THE FUND IS HOLDING A FEW PUT BONDS. WHAT'S THE ATTRACTION OF THESE SECURITIES?

    Put bonds are longer-term  municipal bonds that can be "put  back"--that is,
sold at face  value  to a  specific  dealer  at a  prearranged  date.  The  fund
typically  holds put bonds that can be put back on a  quarterly,  semiannual  or
annual basis.

                       CALIFORNIA TAX-FREE MONEY MARKET

    We usually  retain the  fund's put bonds when their  yields are higher  than
prevailing  yields.  This  situation  occurred in May, when one of our put bonds
reached its annual  "put" date.  Based on one-year  note yields at the time,  we
felt  that  the put  bond  was  more  attractive,  so we  kept it in the  fund's
portfolio.

    Keeping the put bond was the  equivalent of buying a one-year  security,  so
our decision to keep this bond caused the fund's  average  maturity to jump from
18 days to 29 days overnight.

LOOKING AHEAD, WHAT ARE YOUR PLANS FOR THE FUND OVER THE NEXT SIX MONTHS?

    We're looking to extend the fund's  average  maturity  further in the coming
months.  We  already  lengthened  the  fund's  maturity  to more than 50 days by
mid-September, and we'd like to extend another 10-15 days.

    The  next  opportunity  to  extend  will  probably  be the  latter  half  of
September.  Yields tend to be more attractive at the end of a quarter, when many
dealers try to clear out some of their  inventory  and  corporate  buyers reduce
their municipal exposure.

    Beginning in November,  we're also going to be putting tighter  restrictions
on the fund's exposure to Japanese banks.

HOW DO JAPANESE BANKS AFFECT THE FUND'S PORTFOLIO?

    Many California  municipal money market securities are backed by a letter of
credit from a bank, and this may include  Japanese  banks. In the last couple of
years,  the  Japanese  banking  system  has  suffered  from a  lengthy  domestic
recession and bad real estate loans.

    As a result,  we  established  credit  standards  that prevent the fund from
holding more than 10% of its assets in securities  guaranteed by Japanese banks.
This limit is low compared to most other  California  money market funds, but we
plan to reduce this  internal  restriction  even  further--it  will be around 5%
starting in November.

14      CALIFORNIA MUNICIPAL MONEY MARKET      AMERICAN CENTURY INVESTMENTS


                       CALIFORNIA MUNICIPAL MONEY MARKET

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM DURING THE FISCAL YEAR?

    The fund  continued to provide a higher level of tax-exempt  income than the
average California money market fund. For the fiscal year ended August 31, 1997,
the fund had a total return of 3.15%,  compared with the 2.96% average return of
the 54 "California  Tax-Exempt Money Market Funds" tracked by Lipper  Analytical
Services.  (See the Total  Returns  table on the  previous  page for other  fund
performance comparisons.)

HOW DID THE FUND'S POSITIONING CHANGE DURING THE FISCAL YEAR?

    The fund's average maturity  shortened  gradually from around 40 days at the
beginning  of the  period to about 20 days by  mid-March.  This shift was partly
driven by our  expectations  for a  short-term  interest  rate  increase  by the
Federal  Reserve--which  occured in March--but  it also  reflected a shortage of
one-year California municipal securities.  The limited supply depressed one-year
municipal yields; the few attractive  one-year notes we found failed to meet our
strict credit standards.

    In June and July, when most California  municipalities issue one-year notes,
we  extended  the fund's  average  maturity  back out to about 40 days.  We took
advantage of the seasonal  supply by purchasing  several  notes with  attractive
yields.  We would have liked to extend the fund's maturity even further,  but we
were  leery of  buying  too many  securities  with  the  same  6/30/98  maturity
date--the end of the fiscal year for most California municipalities.

ALTHOUGH THE FED RAISED SHORT-TERM RATES IN MARCH, THE FUND'S YIELD IS VIRTUALLY
THE SAME AS IT WAS A YEAR AGO. WHY?

    The Fed's  interest rate changes tend to have less of an impact on municipal
money market  yields than on taxable money market  yields.  The Fed raised rates
from 5.25% to only 5.50%,  and such a small increase  typically has a negligible
effect on municipal money market rates.

    Supply and demand factors have the biggest impact on municipal  money market
rates, and that's why yields haven't changed much over the past year.

THE FUND RECENTLY PURCHASED SOME PUT BONDS. WHAT'S THE ATTRACTION OF THESE
SECURITIES?

    Put bonds are longer-term  municipal bonds that can be "put  back"--that is,
sold at face  value  to a  specific  dealer  at a  prearranged  date.  The  fund
typically  holds put bonds that can be put back on a  quarterly,  semiannual  or
annual basis.

                       CALIFORNIA MUNICIPAL MONEY MARKET

    The put bonds we purchased  for the fund pay interest that is subject to the
federal alternative minimum tax (AMT). Because the supply of one-year California
AMT paper is limited,  we were quick to take  advantage of the put bonds,  which
also gave us an extra 10 basis points in yield compared to non-AMT securities.

DOES THAT MEAN THE FUND IS HOLDING MORE AMT PAPER THAN NORMAL?

    Yes. The fund  typically  invests about 60% of its assets in AMT paper,  but
the put bonds we recently bought pushed that percentage to more than 75%.

LOOKING AHEAD, WHAT ARE YOUR PLANS FOR THE FUND OVER THE NEXT SIX MONTHS?

    We're looking to extend the fund's  average  maturity  further in the coming
months.  We  already  lengthened  the  fund's  maturity  to more than 50 days by
mid-September, and we'd like to extend another 10-15 days.

    The  next  opportunity  to  extend  will  probably  be the  latter  half  of
September.  Yields tend to be more attractive at the end of a quarter, when many
dealers try to clear out some of their  inventory  and  corporate  buyers reduce
their municipal exposure.

    Beginning in November,  we're also going to be putting tighter  restrictions
on the fund's exposure to Japanese banks.

HOW DO JAPANESE BANKS AFFECT THE FUND'S PORTFOLIO?

    Many California  municipal money market securities are backed by a letter of
credit from a bank, and this may include  Japanese  banks. In the last couple of
years,  the  Japanese  banking  system  has  suffered  from a  lengthy  domestic
recession and bad real estate loans.

    As a result,  we  established  credit  standards  that prevent the fund from
holding more than 10% of its assets in securities  guaranteed by Japanese banks.
This limit is low compared to most other  California  money market funds, but we
plan to reduce this  internal  restriction  even  further--it  will be around 5%
starting in November.

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM?

    The fund  continued to perform very well  compared  with its peers.  For the
fiscal year ended August 31, 1997,  the fund's 10.61% return was higher than the
8.98% average  return of the 101  "California  Municipal  Debt Funds" tracked by
Lipper  Analytical  Services.  (See the Total Returns table on the previous page
for other fund performance  comparisons.)  The fund's one-, three- and five-year
returns place it in the top 10% of its peer group.

HOW DID THE FUND'S YIELD STACK UP AGAINST ITS PEERS?

    The fund  continued  to provide  shareholders  with a high level of tax-free
current  income.  As of August 31, 1997,  the fund's 30-day SEC yield was 5.04%,
compared with the 4.23% average yield of its peers.(+)

HOW DID YOU POSITION THE FUND DURING THE FISCAL YEAR?

    We  continued  to avoid making  interest  rate bets that can cause  unwanted
swings  in the  fund's  returns  from  period  to  period.  We made  only  minor
adjustments, keeping the duration fairly neutral compared with the fund's peers.
(Duration  is a measure of the  portfolio's  sensitivity  to changes in interest
rates.) The fund ended the period with a duration of 7.5 years,  unchanged  from
the beginning of the period.

(+)  Although  the fund's yield may be  significantly  higher than the yields of
     other fixed-income funds that purchase higher-rated securities, this higher
     yield is generally  based upon the greater credit risk of the securities in
     the fund's portfolio.

                        CALIFORNIA HIGH-YIELD MUNICIPAL

WHAT FACTORS LED TO THE FUND'S IMPRESSIVE PERFORMANCE?

     A large portion of the municipal  securities the fund owns are  lower-rated
securities  that  benefited  from trends that drove yields  lower.  For example,
strong growth in California's  economy  continued to act as a catalyst,  further
compressing  credit  spreads--the   difference  in  yield  between  higher-  and
lower-rated  securities.  The amount of  lower-quality  California  issues being
backed  by  municipal  bond  insurers  also  continued  to  grow,  which  placed
additional  tightening  pressure  on credit  spreads.  The fund's  returns  were
further enhanced by some securities being prerefunded.

DOES THE  COMPRESSION  OF CREDIT  SPREADS  HAVE ANY BEARING ON YOUR  DECISION TO
POSITION THE FUND'S PORTFOLIO TOWARD THE ENDS OF THE CREDIT SPECTRUM?

    Yes.  During the period,  we employed  what is known as a "credit  barbell,"
where we  focused on  purchasing  more  securities  at the top and bottom of the
credit  spectrum and less from the middle.  This structure tends to perform best
when credit spreads are tightening.

WERE THERE ANY OTHER KEY FACTORS CONTRIBUTING TO THE FUND'S PERFORMANCE?

    Yes.  Another key ingredient to the fund's strong returns is our disciplined
bottom-up,  value-oriented  approach  that  looks  for  securities  that  may be
undervalued by virtue of their credit rating or market valuation.  Based on this
process,  we purchased many municipals in recent years that have  appreciated as
their ratings were raised or the market recognized their value.

    One such example is a Colton,  California  municipal  utility  issue that we
bought approximately two years ago. After extensive research, we determined that
the electric utility's underlying fundamentals would likely lead to stronger and
more  profitable  performance  in the years ahead.  As a result,  we purchased a
non-rated  issue from the utility at a  significantly  higher yield than insured
bonds. Thanks to subsequently improving conditions at the utility, the issue was
recently  refunded,  providing a healthy 15% net gain from the time of purchase.
Of course, not all portfolio holdings are this successful.

WHAT  PART  DOES  THE  MUNICIPAL  CREDIT  RESEARCH  TEAM  PLAY IN  FINDING  SUCH
SECURITIES?

    A  significant  one.  By making  accurate  assessments  of  specific  credit
situations,  the group has helped us steer clear of many issues not  appropriate
for purchase, while locating attractively valued securities that others may have
passed over.  To find such hidden  values,  our credit  research  team  analyzes
detailed  financial  information,  talks directly with  municipal  officials and
frequently travels around the state for on-site visits and tours.  California is
a complex,  dynamic  state,  and  thorough  research is an integral  part of the
security selection process.  We therefore work closely with our municipal credit
research staff to find securities that we feel will enhance fund performance.

WHAT IS THE OUTLOOK FOR MUNICIPAL SECURITIES FOR THE REMAINDER OF 1997?

    Our outlook for municipals is generally  positive.  Inflation  remains tame,
having  risen at a mere 1.6% annual rate during the first eight  months of 1997.
"Real"  interest rates (nominal  interest rates minus  inflation) are relatively
high,  which should  inhibit  inflation and economic  growth going  forward.  In
addition,  strong productivity gains should continue to offset wage gains in the
near  future.  As a result,  we think the Federal  Reserve can  continue to hold
rates steady.

    We also  expect bond  insurers  to  continue to be active in the  California
municipal market, increasing credit quality and generally driving yields lower.
That means credit spreads could continue to narrow.

    Nevertheless, municipal yields may continue to fluctuate, particularly if we
get signs of stronger-than-expected economic growth. For municipal securities to
rally further, it would likely take sharply slower economic growth or a dramatic
drop in inflation.

GIVEN THIS SITUATION, WHAT ARE YOUR PLANS FOR THE FUND OVER THE NEXT SIX MONTHS

    For the near term, we will likely maintain the fund's conservative  duration
positioning.  Since  interest  rates  are  currently  very low,  refundings  may
continue to rise and will therefore bear close  watching.  We will also continue
working  closely  with  our  research  staff  to  uncover   attractively  valued
securities with the potential to enhance the fund's returns. With credit spreads
shrinking, however, these opportunities are fewer and farther between, requiring
us to be more selective than ever. In addition, we will likely continue to favor
a credit  barbell  for the fund in the near  future,  picking up AAA and unrated
municipals that become available at attractive prices.

                          CALIFORNIA INSURED TAX-FREE

MANAGEMENT Q & A

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

HOW DID THE FUND PERFORM?

    The fund  performed  very well  relative  to its peers.  For the fiscal year
ended August 31, 1997, the fund returned 9.25%,  compared with the 8.84% average
return of the 26  "California  Insured  Municipal  Debt Funds" tracked by Lipper
Analytical  Services.  The fund's  three- and  five-year  returns  are even more
impressive.  For example,  the fund's three-year returns place it in the top 10%
of its peer group, while its five-year returns place it in the top 25%. (See the
Total  Returns   table  on  the  previous   page  for  other  fund   performance
comparisons.)

    The fund also produced significantly more current income than the peer group
average.  As of August 31, the fund's 30-day SEC yield was 4.55%,  compared with
the 3.88%  average  yield of the fund's  peers.  One  reason  we've been able to
produce such strong yields and returns is that the fund's expenses are below the
peer group average.  Other things being equal, lower expenses mean higher yields
and returns for our shareholders.

ANNUAL REPORT                           CALIFORNIA INSURED TAX-FREE       31


                          CALIFORNIA INSURED TAX-FREE

HOW WAS THE FUND POSITIONED DURING THE PERIOD?

    We lengthened  the fund's  duration  slightly in the second  quarter to take
advantage  of the  decline  in  interest  rates.  (Duration  is a measure of the
portfolio's  sensitivity to changes in rates.) The longer a fund's duration, the
more its share price  tends to rise when rates  decline.  In  general,  we use a
conservative  approach to managing the fund's  duration,  keeping it in a narrow
range around 8 years. We look to add value to the fund primarily through careful
credit analysis and security selection.

CAN YOU GIVE AN EXAMPLE OF HOW YOU MANAGED THE FUND FOR A  COMBINATION  OF YIELD
AND RETURN?

    Sure. We tried to enhance the fund's yield and return by carefully  managing
the fund's coupon  structure.  For example,  many of the  outstanding  long-term
municipal bonds have coupons between 5.125% and 5.875%.  We put less emphasis on
these  securities,  buying  these  bonds only if there was a  compelling  credit
story.  Instead,  we tried to maintain a "barbell"  coupon  structure,  with the
majority of the fund's assets in  higher-coupon  premium bonds and  lower-coupon
discount and non-callable  bonds. The premium bonds were intended to shorten the
fund's duration, while the lower-coupon discount bonds helped the fund's returns
because  their price tends to rise more rapidly  than  premium  bonds when rates
fall.

HOW HAS THE DEREGULATION OF THE ELECTRIC UTILITY INDUSTRY AFFECTED THE FUND?

    Deregulation has changed the way we look at this sector.  In general,  we're
avoiding new municipal  electric  utility debt because we're uncertain how these
entities will perform when faced with competition.  But the change has been good
for debt issued  before the  reforms  were  enacted.  That's  because  municipal
utilities have been refunding much of that debt to get it off their books.  In a
refunding,    the   issuer   establishes   an   escrow   account   of   Treasury
securities--that's  great  for the fund  because  we  continue  to draw  current
tax-free income on an investment secured by Treasurys.

YOU HELD SOME TREASURY PUT OPTIONS DURING THE PERIOD. WHY?

    We bought Treasury put options as a form of insurance  against a bond market
decline.  (A  put  option  allows  the  bondholder  to  sell  a  security  at  a
pre-determined  price on a specified  date.) Hedging the fund with Treasury puts
allowed us to hold more long-term  municipal  securities than we otherwise would
have felt comfortable  with. That helped the fund because  long-term  municipals
performed well during the period.

                          CALIFORNIA INSURED TAX-FREE

WHAT IS YOUR  OUTLOOK  FOR THE  CALIFORNIA  MUNICIPAL  MARKET  OVER THE NEXT SIX
MONTHS?

    Our outlook for municipals is generally  positive.  Inflation  remains tame,
having risen by just 2.2% for the twelve  months  ended August 31, 1997.  "Real"
interest rates (nominal  interest rates minus the inflation rate) are relatively
high,  which should  inhibit  inflation and economic  growth going  forward.  In
addition,  strong productivity gains should continue to offset wage gains in the
near  future.  As a result,  we think the Federal  Reserve can  continue to hold
rates steady.

    We also  expect bond  insurers  to  continue to be active in the  California
municipal  market,  increasing  credit  quality and driving  down yield  spreads
generally.

    Nevertheless, municipal yields may continue to fluctuate, particularly if we
get signs of stronger-than-expected economic growth. For municipal securities to
rally further, it would likely take sharply slower economic growth or a dramatic
drop in inflation.

WITH THIS OUTLOOK IN MIND, WHAT ARE YOUR PLANS FOR THE FUND GOING FORWARD?

    We'll likely keep the fund's duration slightly longer than neutral, which is
around 8 years.  That should help the fund's  performance if economic growth and
inflation  remain  tame.  We'll also adopt a  contrarian  strategy--buying  when
others sell and selling when they buy.  While we can't  guarantee  this strategy
will be successful, we believe that it is a great range trading strategy because
you're  selling  at peaks and  buying on dips.  We will  also  continue  to work
closely  with  our  credit  research  team  to  look  for  attractively   valued
securities.

BIGI = Bond Investor's Guaranty Inc.

FGIC = Financial Guaranty Insurance Co.

FSA = Financial Security Assurance

GO = General Obligation

MBIA = MBIA Insurance Company

VRDN   = Variable Rate Demand Note. Interest reset date is indicated and used in
       calculating  the  weighted  average  portfolio  maturity.  Rate  shown is
       effective August 31, 1997.

(1)   This security is a zero-coupon  municipal  bond.  The yield to maturity at
      August 31, 1997 is indicated instead of a stated coupon rate.  Zero-coupon
      securities  are  purchased at a  substantial  discount from their value at
      maturity. On May 1, 2000, rate becomes fixed at 5.75%.

(2)   Escrowed in U.S. 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.

40      STATEMENTS OF CHANGES IN NET ASSETS    AMERICAN CENTURY INVESTMENTS


                         NOTES TO FINANCIAL STATEMENTS

AUGUST 31, 1997

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    ORGANIZATION--American  Century California Tax-Free and Municipal Funds (the
Trust) is  registered  under the  Investment  Company Act of 1940 as an open-end
management  investment  company.  American Century - Benham California  Tax-Free
Money Market Fund (Tax-Free Money Market),  American Century - Benham California
Municipal Money Market Fund (Municipal Money Market),  American Century - Benham
California High-Yield Municipal Fund (High-Yield), and American Century - Benham
California  Insured  Tax-Free Fund (Insured) (the "Funds") are four of the seven
funds issued by the Trust.  With the exception of Municipal  Money Market,  each
Fund is  diversified  under the 1940 Act.  The Funds seek income which is exempt
from federal and  California  income taxes.  Tax-Free Money Market and Municipal
Money Market  (collectively "Money Market Funds") seek to obtain as high a level
of interest  income as is  consistent  with prudent  investment  management  and
conservation of  shareholders'  capital.  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,  related to the Funds,  are in  accordance  with  accounting  policies
generally accepted in the investment company industry.

    SECURITY VALUATIONS--Securities held by the Money Market Funds are valued at
amortized  cost,  which  approximates  current market value.  Securities held by
High-Yield and Insured are valued through valuations  obtained from 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 on the date
purchased  or  sold.  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  amortization  of premiums and  discounts.  Premiums and original issue
discounts  are  amortized  daily using the  effective  interest  rate method for
High-Yield and Insured.  Market discounts are recognized as income upon the sale
or maturity of securities for High-Yield and Insured. Premiums and discounts are
amortized daily on a straight-line basis for securities held by the Money Market
Funds.

    INCOME TAX  STATUS--It is the Funds' policy to distribute all net investment
income and net realized capital 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 taxes.

    DISTRIBUTIONS TO SHAREHOLDERS--Distributions  from net investment income are
declared daily and distributed  monthly. The Money Market Funds do not expect to
realize any long-term  capital gains, and accordingly,  do not expect to pay any
capital  gains   distributions.   Distributions  from  net  realized  gains  for
High-Yield and Insured are declared and paid annually.

    At August 31, 1997,  accumulated  net realized  capital loss  carryovers for
Tax-Free Money Market of $298,915 (expiring 1999 through 2004) and for Municipal
Money  Market of $158,606  (expiring  2003  through  2004) may be used to offset
future taxable gains.

    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  are due to differences in the
recognition  of  income  and  expense  items  for  financial  statement  and tax
purposes.

    FUTURES  CONTRACTS--High-Yield  and Insured 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 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  investments  and
unrealized appreciation (depreciation) on investments,  respectively. There were
no open futures contracts at August 31, 1997.

AUGUST 31, 1997

    SUPPLEMENTARY  INFORMATION--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,
American Century Investment  Management,  Inc. (ACIM), the Trust's  distributor,
American  Century  Investment  Services,  Inc., and the Trust's  transfer agent,
American Century Services Corporation (ACSC).

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect the reported  amounts of assets and liabilities and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the reported  amounts of increases  and  decreases in net assets
from  operations  during the  period.  Actual  results  could  differ from these
estimates.

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

     The shareholders of the Funds approved a new management agreement with ACIM
on July 30,  1997,  effective  August 1, 1997,  which  replaced  the  previously
existing contracts between the Funds and Benham Management  Corporation and ACSC
for advisory,  administrative and transfer agency services. Under the agreement,
ACIM  provides all services  required by the fund in exchange for one  "unified"
management  fee.  The annual rate at which this fee is  assessed  is  determined
monthly in a two-step  process:  First,  a fee rate  schedule  is applied to the
assets of all of the funds in the Fund's  investment  category which are managed
by ACIM (the  "Investment  Category Fee"). The overall  investment  objective of
each Fund determines its Investment  Category.  The three investment  categories
are: the Money Market Fund Category,  the Bond Fund Category and the Equity Fund
Category.  Tax-Free Money Market and Municipal  Money Market are included in the
Money Market Fund Category and  High-Yield  and Insured are included in the Bond
Fund Category.  Second, a separate fee rate schedule is applied to the assets of
all of the funds managed by ACIM (the "Complex  Fee").  The Investment  Category
Fee and the Complex Fee are then added to determine the unified  management  fee
rate.  The  management  fee is paid  monthly by each Fund  based on each  Fund's
aggregate  average daily net assets during the previous month  multiplied by the
monthly management fee rate. The annualized Investment Category Fee schedule for
each Fund is as follows:

    Tax-Free Money Market and Municipal Money Market:

      0.2700% of the first $1 billion  
      0.2270% of the next $1 billion 
      0.1860% of the next $3 billion 
      0.1690% of the next $5 billion 
      0.1580% of the next $15 billion 
      0.1575% of the next $25 billion
      0.1570% of the average daily net assets over $50 billion

    High-Yield:

      0.3100% of the first $1 billion  
      0.2580% of the next $1 billion 
      0.2280% of the next $3 billion 
      0.2080% of the next $5 billion 
      0.1950% of the next $15 billion 
      0.1930% of the next $25 billion
      0.1925% of the average daily net assets over $50 billion

    Insured:

      0.2800% of the first $1 billion  
      0.2280% of the next $1 billion 
      0.1980% of the next $3 billion 
      0.1780% of the next $5 billion 
      0.1650% of the next $15 billion 
      0.1630% of the next $25 billion
      0.1625% of the average daily net assets over $50 billion

    The annualized Complex Fee (for all Funds) schedule is as follows:

      0.3100% of the first $2.5 billion 
      0.3000% of the next $7.5 billion 
      0.2985% of the next $15 billion  
      0.2970% of the next $25 billion  
      0.2960% of the next $50 billion 
      0.2950% of the next $100 billion 
      0.2940% of the next $100 billion  
      0.2930% of the next $200 billion 
      0.2920% of the next $250 billion
      0.2910% of the next $500 billion
      0.2900% of the average daily net assets over $1,250 billion

                         INDEPENDENT AUDITORS' REPORT

The Board of Trustees and Shareholders
American Century California Tax-Free and Municipal Funds

    We have  audited  the  accompanying  statements  of assets and  liabilities,
including the schedules of investment  securities,  of American Century - Benham
California  Tax-Free  Money Market Fund,  American  Century - Benham  California
Municipal Money Market Fund,  American  Century - Benham  California  High-Yield
Municipal Fund and American  Century - Benham  California  Insured Tax-Free Fund
(four of the series issued by American Century California Tax-Free and Municipal
Funds)  (the  Funds)  as of August  31,  1997,  and the  related  statements  of
operations for the year then ended,  the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
each  of  the  periods  presented.  These  financial  statements  and  financial
highlights are the responsibility of the Funds'  management.  Our responsibility
is to express an opinion on these financial  statements and financial highlights
based on our audits.

    We conducted  our audits in  accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our  procedures  included  confirmation  of securities  owned as of
August 31, 1997 by correspondence  with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,   as  well  as  evaluating  the  overall   financial   statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

    In our  opinion,  the  financial  statements  and the  financial  highlights
referred to above  present  fairly,  in all  material  respects,  the  financial
position of the Funds as of August 31,  1997,  the results of their  operations,
the  changes in their net assets and the  financial  highlights  for the periods
indicated above in conformity with generally accepted accounting principles.

INVESTMENT PHILOSOPHY & POLICIES

    The Benham Group  offers 38  fixed-income  funds,  ranging from money market
funds to long-term bond funds and including both taxable and tax-exempt funds.

    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 by  investing  in  high-quality
California  municipal money market  securities  with remaining  maturities of 13
months or less.  There can be no  assurance  that  these  funds  will be able to

                                   GLOSSARY

RETURNS

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

* AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations  in a fund's  return;  they are not the same as  fiscal  year-by-year
results.  For  fiscal  year-by-year  returns,  please  refer  to the  "Financial
Highlights" on pages 44-47.

YIELDS

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

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

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

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

INVESTMENT TERMS

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

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

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

STATISTICAL TERMINOLOGY

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

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

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

* EXPENSE RATIO--the  operating expenses of the fund,  expressed as a percentage
of average net assets.

TYPES OF MUNICIPAL SECURITIES

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

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

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

* GO  BONDS--general  obligation  securities  backed by the taxing  power of the
issuer.

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

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

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

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

*   TAX-ALLOCATION   BONDS--securities   issued  to  finance   improvements   in
redevelopment areas (such as urban neighborhoods).

*  VRDNS--variable  rate  demand  notes that  track  market  interest  rates and
stabilize  their market values using  periodic  (daily or weekly)  interest rate
adjustments.
