Period Overview

o    U.S. stocks  continued to produce healthy gains during the six months ended
     May 31, 1997. However, the market experienced significant price volatility.

o    U.S.  bond  performance  was  mixed but  relatively  flat  overall.  Strong
     economic growth in the first quarter of 1997 led to rising interest rates.

o    Among  foreign  stock  markets,  Europe  had the  strongest  returns of any
     region, while Asian markets suffered sizable losses.

o    Foreign bond markets produced  favorable returns as interest rates declined
     around the globe.

o    The  U.S.  dollar  strengthened  against  most  major  foreign  currencies,
     reducing returns from foreign investments. 

Capital Manager

o    Because  of its more  conservative  asset  allocation  structure,  the fund
     underperformed  its Lipper peer group  average  during the six months ended
     May 31, 1997.

o    For most of the six-month period, the fund maintained a neutral position in
     U.S. stocks and bonds, an overweighting in foreign stocks and bonds, and an
     underweighting in cash.

o    The fund also  underweighted  natural  resources  stocks  during the period
     because of poor performance, especially among gold stocks.

o    The fund hedged a portion of its  investments in Europe and Japan to reduce
     the negative effects of the strengthening dollar.

o    Going forward,  we plan to continue  overweighting the fund's foreign stock
     holdings,  especially  in Europe,  while  underweighting  cash and  natural
     resources stocks.

o    Pending  shareholder  approval,  the fund will be merged into the  American
     Century  Strategic:  Conservative  fund, a very similar fund managed by the
     same team.

                               OUR MESSAGE TO YOU

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

The widely divergent performance of the world's financial markets during the six
months ended May 31, 1997,  underscored the importance of diversified investing.
European and American stock markets  produced  strong  returns,  but Far Eastern
stock  markets  suffered  losses.  Domestic  bond returns were mixed,  while the
stronger U.S. dollar hurt foreign bond returns.

Within this environment,  the diversified  portfolio of the Capital Manager fund
produced a positive return consistent with its asset allocation strategy. In the
following pages, our investment management team discusses the performance of the
global financial  markets in more detail and describes how your fund was managed
during the period.

The  Capital  Manager  fund's  management  team,  headed by Jeff Tyler and Brian
Howell,   includes  some  of  American  Century's  most  experienced  investment
professionals.  Recently,  our international  investment team, which manages the
foreign stock portion of the fund,  welcomed Mark Kopinski back after a two-year
stint with another investment company. Kopinski helped create American Century's
international management team in 1991, and his years of experience and expertise
in Asia will be invaluable to the management of our  international  stock funds,
as well as the Capital Manager fund.

We also strengthened our corporate team. In June, Bill Lyons, American Century's
chief operating officer,  was named president,  assuming full responsibility for
the company's day-to-day  operations.  With this change, Jim Stowers III will be
able to focus more time on developing and refining new  investment  technologies
and tools that build on and leverage the proprietary system his father 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 help lead us and our
investors to success in the next century.

The  proposed  merger of the  American  Century  Capital  Manager  fund with the
American Century Strategic Allocation:  Conservative fund is another opportunity
for us to  improve  the way we serve  you.  Our aim is to reduce  the  number of
overlapping  funds that  resulted  when Benham  merged with  Twentieth  Century.
Combining similar funds not only creates greater  efficiencies,  but also allows
fund managers to focus more of their attention on each individual fund.

We appreciate your confidence in American Century and look forward to continuing
to serve you.

Sincerely,

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

                                PERIOD OVERVIEW

U.S. Stocks

The U.S.  stock market,  which has been rising  steadily  since the beginning of
1995, produced healthy gains during the six months ended May 31, 1997. The major
U.S. stock indexes (such as the Dow Jones  Industrials  and the S&P 500) reached
record highs on their way to returns of more than 10% for the six-month period.

Despite solidly positive  returns,  U.S. stocks  experienced  substantial  price
volatility,  especially among the stocks of smaller companies. Uncertainty about
the  economy  and  corporate  earnings  growth  led to a  significant  amount of
day-to-day volatility early in the six-month period.

In February  and March,  concerns  about  rising  interest  rates and  declining
corporate  profits took their toll, and stock prices began to slide.  Technology
companies  and other  "aggressive  growth"  stocks--so  called  because of their
propensity for sharp price  swings--suffered the biggest losses, falling as much
as 25% as a group.

But the downward trend reversed in May, when interest rate expectations  leveled
off and  first-quarter  corporate  earnings reports showed  surprisingly  strong
growth. Aggressive growth stocks produced the strongest rebound,  retracing most
of their earlier losses in just a few weeks.

As the accompanying table shows,  small-capitalization  stocks (such as those in
the Russell 2000) underperformed  large-capitalization  stocks (such as those in
the S&P 500) during the period. This was a continuation of a trend that began in
early  1996,  when  uncertain  investors  fled from  smaller-company  stocks and
flocked to the largest, most-liquid stocks.

The greater  volatility  of small-cap  stocks  compounded  this  disparity.  The
small-cap stock universe includes many aggressive growth stocks,  whose inherent
volatility hurt their performance during the period.

However, the more extreme price swings of small-cap stocks worked in their favor
toward the end of the period.  Renewed optimism and relatively attractive prices
brought  investors back into small-cap stocks in late April.  After reaching its
lowest  point of the period on April 25, the Russell  2000  returned  nearly 14%
through the end of May. By comparison,  the S&P 500 posted a return of about 11%
during the same period.

U.S. Bonds

U.S.  bonds  produced  mixed returns  during the six months ended May 31. Rising
yields  caused bond prices to fall,  but the  interest  paid out to  bondholders
offset  the price  declines  to a large  degree.  Short-term  securities,  which
usually suffer less price depreciation than longer-term securities when interest
rates rise, were the best performers.  For example,  the two-year  Treasury note
posted a 2.2% return for the six-month  period,  while the 30-year Treasury bond
returned -3.6%.

Bond  yields  fell (and bond  prices  rose) at the  beginning  of the  period in
response to evidence of moderating U.S.  economic growth and low inflation.  But
by the beginning of 1997,  stronger  economic  growth and rising wage  pressures
rekindled  concerns  about  inflation.  In  an  effort  to  head  off  potential
inflation, the Federal Reserve raised short-term interest rates in March.

As a result,  bond  yields  soared  throughout  the first  quarter of 1997.  The
30-year  Treasury  bond  yield,  which had  fallen as low as 6.35% in  December,
climbed to 7.10% by the end of March.  The bond market settled down in April and
May, rallying  slightly as inflation  remained subdued and economic growth began
to slow.

Semiannual Report                                           Period Overview    3


                                PERIOD OVERVIEW

Mortgage-backed  securities were the top performers  among U.S. bonds during the
six-month  period,  followed by  corporate  bonds.  With bond  prices  declining
slightly  overall,  yield was the most significant  contributor to bond returns.
Mortgage-backed  and corporate  securities tend to have higher yields than other
domestic bonds.  Treasury  bonds,  which typically offer the lowest yields among
U.S. fixed-income securities, produced the weakest returns.

Foreign Stocks

Global stock returns varied  dramatically  by region during the six months ended
May 31. Europe's stock markets  produced the strongest  returns of any region in
the world,  while Asian markets  suffered  sizable  losses.  The Morgan  Stanley
EAFE(R)  Index--a  broad measure of  international  stock  performance--returned
4.04% (in U.S. dollar terms) during the six-month period.

The  continued  strength of the U.S.  dollar  weighed  heavily on foreign  stock
returns for U.S.  investors.  The dollar rose by 11% against the German mark and
2% against the Japanese yen during the period. As the accompanying  table shows,
the  EAFE(R)'s  return in local  currencies  was  substantially  higher than its
return in dollars.

European stock markets excelled during the period because of favorable  economic
conditions,  falling interest rates and low inflation.  Corporate  restructuring
also  boosted  the  performance  of  European   equities.   Although  Spain  and
Switzerland  were the  top-performing  stock markets in Europe--with  returns of
more  than  30% (in  local  currencies)  during  the  period--nearly  all of the
continent's markets returned 20% or more.

The Japanese stock market  continued to languish.  Although the Japanese economy
showed  signs of life after  seven  years of  recession,  most of the growth was
driven by export industries. The rest of Southeast Asia--including Thailand, the
Philippines  and  Singapore--struggled  as economic growth in the region slowed.
Collapsing  speculative  investments  and a failure to invest in  infrastructure
during the good times  dragged down stock prices in these  countries.  Hong Kong
was a notable  exception,  producing strong stock market performance thanks to a
thriving economy.

Latin America replaced Asia as the hottest region for growth. Political changes,
increased privatization and economic reform have improved the global credibility
of the Latin equity markets.

Foreign Bonds

Foreign bond markets produced  favorable returns during the six months ended May
31 as global interest rates  continued to decline.  However,  the  strengthening
U.S. dollar hurt foreign bond returns for U.S. investors.

As the  index  returns  in the  tables  on  this  page  and  the  previous  page
illustrate, foreign bonds outperformed U.S. bonds in local currencies during the
six-month  period.  But when the foreign bond index's return is translated  into
dollars, U.S. bonds win out by a substantial margin.

Interest rates generally  declined as the world's central banks made a concerted
effort to revitalize  economic growth.  In Europe,  preparation for Economic and
Monetary Union in 1999 held interest  rates down across the continent.  Japanese
rates remained at historic lows as the country tried to end its lengthy economic
downturn.

The exception is Latin America,  where  interest rates have remained  relatively
high.  Many  Latin  American  countries  are  experiencing  explosive  levels of
economic growth,  and the potential for rising inflation has propped up interest
rates.

FOREIGN STOCK MARKET PERFORMANCE
For the six-month period ended May 31, 1997
Morgan Stanley EAFE(R) Index (in U.S. dollars)       4.04%
Morgan Stanley EAFE(R) Index (in local currencies)   8.96%

                                MANAGEMENT Q & A

Management Q & A

An interview with Jeff Tyler and Brian Howell,  lead  portfolio  managers on the
American Century Capital Manager fund management team.

How did the fund perform?

For the six-month  period ended May 31, 1997,  the fund posted a total return of
4.02%,  compared  with the 5.94% average  return of the 215 "Flexible  Portfolio
Funds" tracked by Lipper  Analytical  Services.  (See the Total Returns table on
the previous page for other fund performance comparisons.)

The fund's  more  conservative  asset mix caused it to  underperform  its Lipper
category  average during the period.  However,  the fund's  longer-term  returns
reflect the general  strength of the global  financial  markets since the fund's
inception.

How did the fund's asset mix change over the past six months?

We maintained a neutral  position in domestic stocks and bonds, an overweighting
in foreign  securities  and a  corresponding  underweighting  in cash.  The most
significant  adjustment  we made was to expand the fund's  holdings  of European
stocks, which provided the best equity returns of any region in the world during
the period.

But weren't those returns reduced by the stronger U.S. dollar?

That's true, but even after you account for the currency losses,  European stock
returns  were still on par with U.S.  stock  returns and better than  returns in
other  regions of the world.  In  addition,  we  mitigated  some of the currency
losses by hedging a portion of the fund's foreign  investments  against European
currencies.

What is currency hedging?

It's a strategy designed to reduce or eliminate the negative effects of currency
fluctuations on foreign  investment  returns.  When the U.S. dollar  strengthens
against  foreign  currencies,  gains earned on investments  denominated in those
currencies  translate  into fewer  dollars;  hedging is intended to offset these
currency losses.

For the fund,  currency hedges typically involve forward currency contracts that
allow the fund to lock in a specific  exchange rate.  This approach  removes the
effect of  currency  exchange  rates and  creates a "pure  play" on the  foreign
securities.

Did you hedge all of the fund's European investments?

No. Although the fund can hedge as much as 100% of its foreign  assets,  we only
hedged  about 35% of the fund's  European  holdings.  We felt this was a prudent
amount that would help  mitigate  currency  losses  while  retaining  the fund's
exposure to non-dollar-denominated investments.

We also hedged a portion of the fund's Japanese holdings early in the period. We
removed the hedge in April, when the dollar reached a four-year high against the
Japanese yen and Japanese finance ministry  officials  publicly  expressed their
desire for a weaker dollar.

You reduced the fund's  small  (typically  3%)  weighting  in natural  resources
stocks by half. Why?

Natural  resources  investments,  especially  gold stocks,  were among the worst
performers during the six-month period. These investments are traditionally used
as a hedge against rapidly rising  inflation,  but global inflation has remained
low for the past

several years. In addition,  many of the world's central banks have been selling
a portion of their gold  reserves,  leading to further  declines in the price of
gold. Add a couple of fraudulent  claims that have undermined the credibility of
the gold mining industry, and you can see why these stocks have languished.

What are your plans for the fund's asset allocation structure going forward?

We will likely continue its current  positioning--neutral in domestic stocks and
bonds,  overweighted  in foreign  stocks and  bonds,  underweighted  in cash and
natural resources  stocks. We still think the most attractive  opportunities are
in the stock  markets of Europe,  where we see  parallels  with the U.S.  in the
early 1990s.

Coming out of a recession,  U.S. corporations used technological  innovation and
downsizing  to cut costs,  improve  efficiency  and  increase  productivity.  In
addition,  the rise of temporary employment services and outsourcing changed the
nature of the U.S. labor market and lowered the unemployment rate.

Much of Europe is now in the same  situation--a  weak economic  environment  and
high levels of unemployment  are leading to changing labor markets and corporate
restructuring.  We expect  these  changes to boost  corporate  profits in Europe
going forward.

What about the U.S. stock market?

We continue to marvel at the resiliency of the U.S.  stock market.  We've stated
our reservations about the market's stretched valuations,  but stock prices have

continued to climb. Despite our concerns, we followed our asset allocation model
and maintained the fund's neutral weighting in domestic stocks.

The  danger  to U.S.  stocks in the  second  half of 1997 is  stronger  economic
growth, which would likely result in rising inflation and higher interest rates.
Higher rates could squeeze  corporate  earnings,  and weaker earnings growth has
been  responsible  for much of the  punishment  and volatility in the U.S. stock
market recently.

What's your outlook for the bond market?

We  feel  that   interest   rates  have  bottomed   worldwide,   and  we  expect
stable-to-rising  interest rates going forward.  The Federal Reserve has already
raised rates in the U.S., and economic growth is likely to pick up in Europe and
Japan by the end of the year.

As a result,  our outlook is neutral to somewhat  negative for bonds, and we may
look to reduce the fund's  bond  position  later this year.  We could see fairly
flat bond performance worldwide over the next six months, much like the past six
months.

In July,  fund  shareholders  will vote on a proposal to merge the fund into the
American  Century  Strategic  Allocation:  Conservative  fund. If this merger is
approved, how will it affect the fund's management?

The Strategic  Conservative  fund's  investment  policies and asset mix are very
similar to those of the Capital  Manager  fund--a  fairly equal balance  between
stocks and bonds, the same percentage of assets devoted to foreign  investments,
the same 15% weighting in cash, and the same fund management team.

However,   there  are  some   differences,   most  notably  that  the  Strategic
Conservative fund holds a higher  percentage of bonds (45%,  compared to Capital
Manager's  41%) and has no  specific  portion  set aside for  natural  resources
stocks.

1. Organization and Summary of Significant Accounting Policies

Organization--American Century Manager Funds (the Trust) is registered under the
Investment Company Act of 1940 as an open-end diversified  management investment
company.  American  Century  Capital  Manager  Fund (the  Fund) is the sole fund
issued by the Trust.  The Fund's  investment  objective  is to seek to  maximize
total return (capital appreciation plus dividend income) consistent with prudent
investment  risk.  The Fund seeks to achieve this  objective by  allocating  its
assets among U.S. equity securities,  U.S fixed-income securities,  money market
instruments,  foreign  equity and  fixed-income  securities,  and  securities of
companies with  substantial  gold-related  assets and natural  resources  linked
investments. The following significant accounting policies, related to the Fund,
are in accordance with accounting  policies generally accepted in the investment
company industry.

Security  Valuations--Portfolio  securities  traded  primarily  on  a  principal
securities  exchange are valued at the last reported sales price, or the mean of
the  latest  bid and  asked  prices  where no last  sales  price  is  available.
Securities traded  over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price,  depending on local  convention or regulation.  Debt securities not
traded on a principal securities exchange 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--Dividend  income less  foreign  taxes  withheld  (if any) is
recorded as of the ex-dividend date.  Interest income is recorded on the accrual
basis and includes amortization of discounts and premiums.

Foreign Currency Transactions--The accounting records of the Fund are maintained
in U.S.  dollars.  All assets and  liabilities  initially  expressed  in foreign
currencies  are  converted  into U.S.  dollars  at  prevailing  exchange  rates.
Purchases and sales of investment securities,  dividend and interest income, and
certain  expenses  are  translated  at the rates of exchange  prevailing  on the
respective dates of such transactions.

Net  realized  foreign  currency  exchange  gains or losses  arise from sales of
foreign  currencies  and the  difference  between  asset and  liability  amounts
initially stated in foreign  currencies and the U.S. dollar value of the amounts
actually  received or paid. Net unrealized  foreign  currency  exchange gains or
losses  arise from  changes in the value of assets and  liabilities,  other than
portfolio securities, resulting from changes in the exchange rates.

Net realized and unrealized  foreign currency exchange gains or losses occurring
during the holding  period of portfolio  securities  are a component of realized
gain  (loss)  on  investments  and  unrealized  appreciation  (depreciation)  on
investments, respectively.

Forward Foreign  Currency  Exchange  Contracts--The  Fund may enter into forward
foreign  currency  exchange  contracts  for the  purpose  of  settling  specific
purchases or sales of securities  denominated in a foreign  currency or to hedge
the Fund's  exposure  to  foreign  currency  exchange  rate  fluctuations.  When
required,  the Fund will segregate  assets in an amount  sufficient to cover its
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held  by the  Fund  and the
resulting  unrealized  appreciation or depreciation  are determined  daily using
prevailing exchange rates.  Forward contracts involve elements of market risk in
excess of the amount reflected in the Statement of Assets and  Liabilities.  The
Fund bears the risk of an unfavorable  change in the foreign  currency  exchange
rate  underlying  the forward  contract.  Additionally,  losses may arise if the
counterparties do not perform under the contract terms.

Futures  Contracts--The  Fund may enter into stock index  futures  contracts  in
order to manage the Fund's exposure to changes in market conditions.  One of the
risks of entering into futures  contracts may include the  possibility  that the
change in value of the contract may not  correlate  with the changes in value of
the underlying  securities.  Upon entering into a futures contract,  the Fund is
required to deposit  either cash or  securities  in an amount equal to a certain
percentage  of  the  contract  value  (initial  margin).   Subsequent   payments
(variation  margin)  are made or  received  daily,  in cash,  by the  Fund.  The
variation  margin is equal to the  daily  change  in the  contract  value and is
recorded as unrealized gains and losses.  The Fund recognizes a realized gain or
loss when the contract is closed or expires.  Net realized and unrealized  gains
or losses  occurring  during  the  holding  period of  futures  contracts  are a
component of realized gain (loss) on  investments  and  unrealized  appreciation
(depreciation)  on  investments,   respectively.  There  were  no  open  futures
contracts at May 31, 1997.

                         NOTES TO FINANCIAL STATEMENTS

MAY 31, 1997 (UNAUDITED)

Repurchase  Agreements--The  Fund may  enter  into  repurchase  agreements  with
institutions that the Fund's investment advisor,  Benham Management  Corporation
(BMC), has determined are creditworthy pursuant to criteria adopted by the Board
of Trustees.  Each  repurchase  agreement is recorded at cost. The Fund requires
that the securities purchased in a repurchase  transaction be transferred to the
custodian in a manner  sufficient to enable the Fund to obtain those  securities
in the event of a default under the  repurchase  agreement.  BMC monitors,  on a
daily basis,  the value of the securities  transferred to ensure that the value,
including accrued interest, of the securities under each repurchase agreement is
greater than amounts owed to the Fund under each repurchase agreement.

Joint Trading  Account--Pursuant  to an Exemptive Order issued by the Securities
and  Exchange  Commission,  the Funds,  along with other  registered  investment
companies having management  agreements with BMC and American Century Investment
Management,  Inc.  (ACIM),  may transfer  uninvested  cash balances into a joint
trading  account.  These  balances  are  invested  in  one  or  more  repurchase
agreements that are collateralized by U.S. Treasury and Agency obligations.

Income Tax  Status--It  is the Fund's 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 to shareholders are recorded on the
ex-dividend date. Distributions from net investment income are declared and paid
quarterly. Distributions from net realized gains are declared and paid annually.

The character of distributions  made during the year from net investment  income
or net  realized  gains may differ  from  their  ultimate  characterization  for
federal income tax purposes.  These differences are primarily due to differences
in the  recognition of income and expense items for financial  statement and tax
purposes.

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. (ACC), the parent of the Trust's  investment  advisor,
BMC, the Trust's distributor,  American Century Investment Services, Inc. (ACIS)
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.

Organizational  Costs--Costs  incurred  by  the  Fund  in  connection  with  its
organization,  initial  registration,  and public  offering  of shares are being
amortized on a straight-line basis over a five-year period ending November 1999.

- --------------------------------------------------------------------------------
2. Transactions with Related Parties

The  Trust has  entered  into an  Investment  Advisory  Agreement  with BMC that
provides  the  Trust  with  investment  advisory  services  in  exchange  for an
investment  advisory  fee.  ACSC pays all  compensation  of Trust  officers  and
trustees who are officers or  directors  of ACC or any of its  subsidiaries.  In
addition,  promotion and  distribution  expenses are paid by BMC. The investment
advisory  fee is paid  monthly  based on the Fund's  average  daily  closing net
assets  during the  previous  month.  The annual  investment  advisory fee is as
follows:

          0.65% of the first $100 million 
          0.60% of the next $100 million 
          0.55% of the next $100 million  
          0.50% of the next $100 million 
          0.45% of the next $100 million  
          0.37% of the next $1 billion 
          0.34% of the next $1 billion
          0.31% of the next $1 billion  
          0.30% of the next $1 billion 
          0.29% of the next $1 billion 
          0.28% of the next $1 billion
          0.27% of the average daily net assets over $6.5 billion

The Trust has an  Administrative  Services and Transfer  Agency  Agreement  with
ACSC. Under the Agreement,  ACSC provides  substantially all  administrative and
transfer agency services  necessary to operate the Fund. Fees for these services
are based on  transaction  volume,  number of accounts and average daily closing
net assets for funds advised by BMC.

                         NOTES TO FINANCIAL STATEMENTS

MAY 31, 1997 (UNAUDITED)

The Trust has an additional agreement with BMC pursuant to which BMC established
a contractual  expense guarantee that limits Fund expenses (excluding items such
as brokerage  commissions,  taxes,  interest,  custodian  earnings credits,  and
extraordinary expenses) to 1.00% of the Fund's average daily closing net assets.
The agreement  provides that BMC may recover amounts  (representing  expenses in
excess of the Fund's expense  guarantee  rate) absorbed  during the preceding 11
months,  if , and to the extent that, for any given month,  the Fund's  expenses
are less than the expense guarantee rate in effect at that time.

The payable to affiliates as of May 31, 1997,  based on the above agreements was
as follows:
Investment Advisor ........................  $34,786
Administrative Services and
Transfer Agent ............................   30,003
                                            --------
                                             $64,789
                                            ========

On April 25, 1997, the Board of Trustees  approved a plan to implement a unified
management fee, which would replace the existing  contracts between the Fund and
related parties.  Such plan is subject to shareholder approval and will be voted
on in July,  1997.  The results of the vote were unknown at the time this report
was printed.

The Trust has a  Distribution  Agreement  with ACIS,  which is  responsible  for
promoting sales of and distributing the Trust's shares.

- --------------------------------------------------------------------------------
3. Investment Transactions

Purchases and sales of securities, other than short-term securities,  aggregated
$30,203,438  and  $34,000,612,   respectively,   of  which  U.S  government  and
government   agency   obligations    aggregated   $5,545,076   and   $6,293,244,
respectively.  On May 31,  1997,  accumulated  net  unrealized  appreciation  on
investments,  based on the aggregate  cost of  investments  of  $78,270,356  for
federal   income  tax  purposes,   was   $6,183,264   consisting  of  unrealized
appreciation of $7,578,034 and unrealized depreciation of $1,394,770 .

                         RETIREMENT ACCOUNT INFORMATION

As required by law, any distributions you receive from an IRA and certain 403(b)
distributions  [not  eligible for  rollover to an IRA or to another  403(b)] are
subject to federal income tax withholding at the rate of 10% of the total amount
withdrawn,  unless you elect not to have withholding apply. If you don't want us
to withhold  on this  amount,  you may send us a written  notice not to have the
federal  income tax withheld.  Your written  notice is valid for six months from
the date of  receipt  at  American  Century.  Even if you plan to roll  over the
amount you withdraw to another tax-deferred  account, the withholding rate still
applies to the withdrawn  amount unless we have received a written notice not to
withhold federal income tax within six months prior to the withdrawal.

When  you plan to  withdraw,  you may  make  your  election  by  completing  our
Exchange/  Redemption form or an IRS Form W-4P. Call American Century for either
form.  Your  written  election  is valid  for only six  months  from the date of
receipt at American Century. You may revoke your election at any time by sending
a written notice to us.

Remember,  even if you elect not to have income tax withheld, you are liable for
paying income tax on the taxable portion of your withdrawal. If you elect not to
have income tax withheld or you don't have enough income tax  withheld,  you may
be responsible  for payment of estimated tax. You may incur  penalties under the
estimated  tax rules if your  withholding  and  estimated  tax  payments are not
sufficient.

                             BACKGROUND INFORMATION

Investment Philosophy & Policies

Each asset  allocation fund offered by American Century invests in a diversified
portfolio of stocks,  bonds and money market  securities,  with the objective of
achieving as high a level of total return as is consistent  with the fund's risk
profile,  given its asset mix.  The funds rely on a team  management  approach--
groups of managers are  responsible  for the ongoing  active  management  of the
individual fund components.

Capital  Manager  emphasizes a balance  between  stocks and bonds,  along with a
lesser  allocation  of money  market  securities  and  natural  resources-linked
investments.

Comparative Indices

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

The S&P 500  Index is  composed  of 500  large-capitalization  stocks  traded on
domestic exchanges.  It is considered to be a broad measure of U.S. stock market
performance.

The Lehman Aggregate Bond Index is composed of the Lehman Government/  Corporate
Index and the Lehman  Mortgage-Backed  Securities  Index.  It reflects the price
fluctuations of Treasury  securities,  agency securities,  corporate bond issues
and mortgage-backed securities.

The Morgan  Stanley  Europe,  Australia,  Far East  (EAFE(R))  Index is a widely
followed group of stocks from 20 different countries.

The  Salomon  Brothers   Non-U.S.   World  Government  Bond  Index  consists  of
fixed-income government bonds from 13 countries.

The  Three-Month  Treasury Bill Index is derived from secondary  market interest
rates as published by the Federal Reserve Bank.

24   Background Information                         American Century Investments


                                    GLOSSARY

Returns

o 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.

o 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 page 21.

Stock Portfolio Statistics

o Number of  Companies--the  number of different  companies  held by a fund on a
given date.

o Dividend Yield--a  percentage return calculated by dividing a company's annual
cash dividend by the current market value of the company's stock.

o  Price/Earnings  Ratio--a  stock value  measurement  calculated  by dividing a
company's stock price by its earnings per share,  with the result expressed as a
multiple instead of a percentage.  (Earnings per share is calculated by dividing
a company's after-tax earnings by its outstanding shares.)

Bond Portfolio Statistics

o Number of Securities--the  number of different  securities held by a fund on a
given date.

o  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.  The
longer the WAM, the more interest rate  exposure and  sensitivity  the portfolio
has.

o  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.  As the
duration  of a portfolio  increases,  so does the impact of a change in interest
rates on the value of the portfolio.

Fixed-Income Security Types

o Corporate  Securities--debt  securities or instruments issued by corporations.
Short-term  corporate  securities  are typically  issued to raise cash and cover
current  expenses  in  anticipation  of  future  revenues;  long-term  corporate
securities  are  issued  to  finance  capital  expenditures,  such as new  plant
construction or equipment purchases.

o Foreign Government Securities--debt securities issued or guaranteed by foreign
governments or their political subdivisions. Some of these securities are direct
obligations  of the  issuing  government;  others  are  backed  by some  form of
government sponsorship.

o Mortgage-Backed  Securities--debt securities that represent ownership in pools
of  mortgage   loans.   Most   mortgage-backed   securities  are  structured  as
"pass-throughs"--the monthly payments of principal and interest on the mortgages
in the pool are  collected by the bank that is servicing  the  mortgages and are
"passed through" to investors.  While the payments of principal and interest are
considered  secure (many are backed by government agency  guarantees),  the cash
flow is less certain than in other fixed-income investments.  Mortgages that are
paid off early reduce future interest payments from the pool.

o U.S. Government Agency  Securities--debt  securities issued by U.S. government
agencies  (such as the Federal Home Loan Bank and the Federal Farm Credit Bank).
Some  agency  securities  are  backed by the full  faith and  credit of the U.S.
government,  while others are guaranteed only by the issuing agency.  Government
agency  securities  include  discount  notes  (maturing in one year or less) and
medium-term notes, debentures and bonds (maturing in three months to 50 years).

o U.S.  Treasury  Securities--debt  securities  issued by the U.S.  Treasury and
backed by the direct  "full  faith and  credit"  pledge of the U.S.  government.
Treasury  securities  include  bills  (maturing  in one  year  or  less),  notes
(maturing in two to ten years) and bonds (maturing in more than ten years).
