Our Message to You

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

     The twelve months ended November 30, 1998, was an eventful period in global
equity markets.  Weakening financial  conditions brought on by problems in Asia,
Russia,  and Latin  America  threatened  to apply the brakes to global  economic
growth.  This led to significant  stock market volatility and a dramatic decline
in interest rates in industrialized  countries. Once again, the more-established
markets of Europe outperformed the less-established emerging markets.

     American  Century's  international  funds  performed well in this difficult
environment,  either beating or nearly  matching their  benchmark  indices.  Our
disciplined  focus on  earnings  growth  continued  to direct our  international
investment  team toward  companies with strong  competitive  prospects in stable
markets.

     Even in the uncertain markets of emerging  economies,  our team was able to
find  individual  companies that we believe have  sustainable  earnings  growth.
Their stock was often available at very attractive  prices.  As emerging markets
recover, we believe these companies should be positioned for a vigorous rebound.

     The  psychology  of many  international  investors is still very  skittish,
however.  Given the gains in both foreign and domestic  equity  markets over the
last several years, it is understandable  that  investors--especially  those who
are new to foreign markets--might find the broad price swings we've seen in 1998
stressful.  In  our  experience,  these  fluctuations  are an  inevitable,  even
necessary,  part of the investment process. They often set the stage for further
advances. But whatever a market's direction, it does not pay to get caught up in
its excesses,  whether overly optimistic or overly  pessimistic.  If you have an
investment  plan,  stay with it. If you don't have a plan,  this might be a good
time to develop one.

     Another situation we've been watching closely is preparation of the world's
computer  systems  for the  year  2000.  At  American  Century,  we're  devoting
substantial  resources to this endeavor.  Throughout  1999, our technology  team
will be  extensively  testing our systems,  including  those  involved with fund
performance and dividend payments.

     As we close  1998,  the year that  marks our 40th  anniversary,  we wish to
thank you for your investment with American Century.

Sincerely,

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

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

MARKET PERSPECTIVE

*   During our international  funds' fiscal year, which ended November 30, 1998,
    financial  markets in  emerging  economies  continued  to  underperform  the
    markets of large, mature economies.

*   As a result of huge loans to  troubled  emerging  economies,  Europe and the
    United States still appeared vulnerable to the "Asian contagion."

*   There is currently too much excess  manufacturing  capacity  globally.  Even
    when  overcapacity  dissipates as the world's  depressed  economies begin to
    grow again, it is unlikely global  financial  markets will move in lockstep.
    The world's geopolitics are simply too diverse.

*   Europe    is   now    the    headquarters    of   some    unique    industry
    franchises--high-quality   companies   with   products   and  market   share
    unavailable here in the United States.

INTERNATIONAL GROWTH

*    International  Growth's  Investor  Class shares posted a healthy return for
     the year ended November 30, 1998. The fund outperformed its benchmark,  the
     Morgan Stanley  Capital  International  EAFE Index, as well as most foreign
     stock funds.

*    Fund performance benefited from holdings in pharmaceutical companies, banks
     and  financial  services  firms,  machinery and  equipment  companies,  and
     software and insurance firms. Many of these  top-performing  companies were
     located in Europe.

*    Other  top-performers  included  communications-related   companies  Nokia,
     Vodafone  Group,  Telefonica SA and Telecom  Italia SPA. All are benefiting
     from the rapid  expansion  of and  demand for  telecommunications  services
     taking place across Europe.

*    International   Growth's   worst-performing   sectors  for  the  year  were
     electronic  components,  autos and auto  parts  businesses,  airlines,  and
     energy services and exploration companies.

INTERNATIONAL DISCOVERY

*   International Discovery trailed its benchmark,  but outperformed most of its
    peers.

*   Fund  performance was constrained by holdings in Brazil,  Thailand,  Israel,
    Sweden and Japan.

*   Most of the fund's worst-performing companies suffered as a result of global
    economic turmoil rather than weaknesses in their  fundamental  operations or
    business.

*   Financial  services  stocks were among the fund's largest  holdings and also
    its top contributors to performance.

*   The third-quarter  correction  provided an opportunity to add to our fastest
    and most consistently  growing holdings and to diversify  slightly more into
    Asian companies.

EMERGING MARKETS

*   Emerging  Markets had a loss for its fiscal year,  but performed much better
    than its benchmark index.

*   The  fund's  strong  relative  performance  was  largely  the  result of our
    bottom-up investment approach and disciplined focus on earnings growth.

*   Performance was helped by holdings in banks, computer software companies and
    electronic components manufacturers.

*   We increased  positions in several  countries in Southeast  Asia,  where the
    investing  environment  has  improved.  Holdings  in Israel and Mexico  were
    reduced.

Market Perspective from Robert C. Puff, Jr.

Management

HOW THE MARKETS PERFORMED

     During our international funds' fiscal year, which ended November 30, 1998,
financial markets in emerging economies continued to underperform.  However, the
equity markets of large,  mature foreign  economies tended to track our domestic
markets.  The S&P 500 Index,  a  benchmark  for large  stocks here in the United
States,  peaked July 17 and then dropped nearly 20% over the next six weeks. The
Morgan Stanley Capital  International EAFE Index (EAFE),  which represents world
markets outside the U.S. and Latin America, peaked in July as well, and was also
down almost 20% at the end of September.

     EAFE bounced  back in October and  November and finished the November  year
with a gain of 16.45%.  In contrast,  the Morgan Stanley  Emerging  Markets Free
Index lost 22.42% for the year. This  performance  disparity was also evident in
the second half of the year (June-November). Despite the extreme volatility that
characterized the last six months,  EAFE managed a slight gain of 0.34%, but the
Emerging  Markets Free Index lost 16.42%.  This index  suffered from weakness in
Russia and the developing  economies of Eastern  Europe and Latin America.  EAFE
was buoyed by European  markets  which  rallied along with the U.S. The chart on
this page provides results from the various regions.

PUSHING ON A STRING

     One irony of global commerce is that  competitors  are also  customers.  In
fact,  unprecedented  efforts  by the  International  Monetary  Fund  (IMF)  and
governments  in  Europe,  the  Americas,  and  Asia to bail out  their  flagging
competitors were, as well,  attempts to keep the global consumer base intact. By
lending  generously  to  their  global  neighbors,  healthy  economies  hoped to
inoculate  themselves  against the Asian,  and later the Russian and  Brazilian,
"flu."

     Despite  huge  loans to these  troubled  economies,  Europe  and the United
States still appeared  vulnerable to the "Asian  contagion."  The United Kingdom
has, in fact,  slipped into a recession,  even though it reduced  interest rates
and is benefiting  from the  orchestrated  decline of rates  throughout  Europe,
where the European Monetary Union kicked off January 1. In the U.S., the Federal
Reserve Board lowered rates three times beginning September 30 -- its first such
moves  since 1995 -- and many  foreign  markets  rallied as a result.  But it is
still uncertain how much effect these rate reductions will have.

     There is, quite frankly,  too much of almost everything.  For example,  the
global production capacity for automobiles is roughly 28-29 million per year, or
about  50%  higher  than  demand.  Much the  same is true  for key  commodities,
including  basic  foodstuffs,  steel,  petrochemicals,   and  energy.  Too  much
manufacturing capacity, combined with global competition, has eliminated pricing
flexibility  from the marketplace  and  contributed to low inflation  worldwide.
Lower interest rates may help the situation, but it is questionable

Market Perspective from Robert C. Puff, Jr.
- --------------------------------------------------------------------------------
                                                                    (Continued)

as to whether they will have much impact on demand in the near future.

     Lowering  rates at this stage is, in effect,  like pushing on a string.  In
mature  economies,  many consumers already have all they need; lower rates won't
necessarily induce them to buy more.

     At some  point,  of course,  overcapacity  will  dissipate  as the  world's
depressed  economies begin to grow again.  There are already signs, for example,
of a more responsible  approach to the Japanese banking and economic crises,  as
well as indications of renewed growth in Korea and Thailand.  But in the current
environment,  deflation  remains a threat,  and  countries  including the United
States may be tempted to fall into the trap of protectionism. U.S. manufacturers
have already petitioned for tariffs to counteract the dumping of steel and wheat
by foreign producers. Globally, trade with Asia is largely one-way; ships arrive
full from the Far East, but travel empty on the return trip. For now, most Asian
consumers aren't buying.

CONTRAST AND CONVERGENCE

     In many  respects,  global  citizens have more and more in common with each
other and are more economically interdependent.  Increasingly,  we have the same
media exposure.  More of the world's economic  activities are  orchestrated,  as
evidenced in the current crises, where larger, more-established governments have
stepped in to provide loans to ailing financial systems.  Before it defaulted on
its debt, even Russia borrowed money from the IMF and Japan.

     There  is, as well,  the  bipartisan  effort on the part of Europe  and the
United States to help solve Japan's economic problems so that Asia, in turn, can
recover.  Many Japanese  banks are buried under  non-performing  loans,  many of
which  were taken out over a decade ago to  purchase  real  estate and stocks at
inflated  prices.  The  Japanese  government  has been  subsidizing  these  loan
portfolios for years, which has served to prolong the country's  recession.  The
Japanese tend to be gradualists, however, so it will probably still take time to
get the  economy  moving  again.  Japan's  recent  tax cuts and its  efforts  to
stabilize the banking system are steps in the right direction.

A NEW DISCIPLINE IN EUROPE

     The European  Monetary Union will bring  together an unusual  collection of
countries.  Only a few years ago, Italian inflation was in double digits,  while
German tax rates were so high that  companies  were loath to show a profit.  Now
merger and  acquisition  activity in Europe is rolling  right along as companies
seek to broaden their base,  take  advantage of economies of scale,  and compete
globally.  The environment is similar to that of the United States in the late '
80s.

     Europe   is   also   the    headquarters    of   some    unique    industry
franchises--high-quality  companies  with products and market share  unavailable
here in the United States -- for example,  companies like  Daimler-Chrysler  and
SAP, the premiere provider of business management software.  Not so long ago, it
was  difficult  to buy stock in European  companies of this  quality.  Now it is
relatively easy.

     From that perspective, economic convergence is a highly desirable trend.

International Growth--Q&A
- --------------------------------------------------------------------------------

[photo of Mark Kopinski and Henrik Strabo]

Mark Kopinski and Henrik Strabo, portfolio managers on the International Growth
Fund

     An interview  with Henrik Strabo and Mark Kopinski,  portfolio  managers on
the International Growth team

HOW DID INTERNATIONAL GROWTH PERFORM DURING ITS FISCAL YEAR?

     International  Growth  posted a healthy  16.74%*  return  for the 12 months
ended  November 30, 1998, a year that included one of the most volatile  periods
on record for global  equity  markets.  International  Growth  outperformed  its
benchmark,  the Morgan Stanley Capital  International  EAFE Index (EAFE),  which
gained  16.45%,  and also  outperformed  most foreign stock funds.  According to
Lipper, Inc. (formerly Lipper Analytical Services), a mutual fund research firm,
the fund finished the year in the top 15% of 511 international funds.(+)

     Although we are pleased  that  International  Growth  produced  such strong
relative  performance,  we wish to  stress  that we use the EAFE  Index  only to
relate investment  performance to a publicly  available index.  Because we use a
bottom-up style,  evaluating  individual  companies,  we tend to own a number of
stocks that are not represented in EAFE. As a result, the fund's performance may
or may not resemble that of the index.

ALONG WITH INCREASED MARKET VOLATILITY, WHAT OTHER FACTORS INFLUENCED
PERFORMANCE THIS YEAR?

     The  year  was one of the  most  turbulent  on  record  for  foreign  stock
investments.  The fertile  investment  environment  and healthy  gains in growth
stocks  during the first half of the year turned  negative in the summer of 1998
and gathered steam in the fall.  This was followed by a gradual  recovery during
the final quarter of the year.

     The collapse of the Russian economy and the worst Japanese  recession since
World War II roiled world  markets.  The  situation  was  compounded by concerns
about Brazil, where economic  uncertainty  threatened to spread throughout Latin
America.  Market psychology was further dampened by the near collapse of a major
global hedge fund,  increasing  the fear of  instability  throughout  the global
financial system.

     The third calendar quarter was the worst in eight years for the EAFE Index.
Price swings in market  averages  were often  irrational  and driven more by the
sudden illiquidity and uncertainty of the markets than by fundamentals.

     During the last two years,  our discipline  led us to many rapidly  growing
European  companies.  The portfolio was structured to take advantage of this and
we were able to invest in numerous companies with growing earnings and revenues.
For most of the year, European markets performed exceptionally well.

     As market conditions deteriorated  worldwide,  Europe experienced a painful
selloff;  liquidity all but dried up for a time. We were not well positioned for
the movement  against  European growth stocks and our performance  suffered as a
result.

*All fund returns referenced in this interview are for Investor Class shares.

(+)According to Lipper, for the periods ending November 30, 1998,  International
Growth  was  ranked 13 out of 304  international  funds for three  years and was
ranked 16 out of 147 international  funds for five years. Past performance is no
guarantee of future results.

International Growth--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

     Global  equity  markets have since  stabilized  and have started to make up
some of the ground  lost during the early fall  downturn.  We believe a sense of
balance has returned to many of these  markets.  We are building on these events
to make refinements in the portfolio, which we will explain later.

WHICH SECTORS OR STOCKS CONTRIBUTED  TO INTERNATIONAL GROWTH'S PERFORMANCE THIS
YEAR?

     We found earnings growth in several  industry groups,  including  financial
services,  pharmaceuticals,  banking,  machinery and  equipment,  software,  and
insurance  companies.  Many of the  individual  companies  in these  groups were
located in Europe.

     Characteristic of a new style of corporate management emerging in Europe is
Vivendi.  This was formerly a state-run French water utility, but new management
transformed   the  company  into  a  broad-based   communications,   publishing,
multimedia and construction conglomerate.  The company recently acquired Cendant
Software, one of the world's leading producers of computer games and educational
software.

     Vivendi has much in common with Mannesmann AG, one of our largest  holdings
and  best-performing  stocks.   Mannesmann,  a  German   telecommuni-cation  and
engineering  firm,  is a leading  provider  of  cellular  telephone  service  in
Germany.

     The competitive environment in the European  telecommunications industry is
changing  rapidly.  Mannesmann is one of the principal  purveyors of alternative
access  and is pushing  ahead in its  efforts  to become a leading  provider  of
electronic commerce services and high-speed data  communications.  The company's
telecommunications  unit  posted 38% sales  growth in the first  nine  months of
1998, and its customer base is growing  rapidly.  Mannesmann is one of the first
companies  to compete  with  Deutsche  Telekom AG, the former  German  telephone
monopoly, in the field of local networks.

     We also had  success  with  several  other  communications-related  stocks,
including Nokia, Vodafone Group, Telefonica SA and Telecom Italia SPA.

     Nokia,  a Finnish  company,  continues to confound the  skeptics.  Reported
earnings growth is always well above target rates,  despite the market's general
disbelief in rapid and greater cellular phone penetration. Nokia's earnings have
been buoyed by high demand for its innovative wireless communications equipment,
and the company has been  especially  successful at winning  market share in the
handset arena. The other companies in this group are cellular network providers,
which are benefiting  from rising rates of  penetration  in a rapidly  expanding
market.

     Financial   services  and  banking   stocks   combine  to   represent   the
second-largest  industry group in the portfolio.  Baer Holding AG, Axa-UAP,  and
ING Group were some of our better-performing bank and financial stocks. Earnings
growth is  increasingly  evident in companies  engaged in asset  manage-ment and
banking.  Pension reform and Europe's changing attitude toward the investment of
personal  savings,  with an  increasing  appetite for  equities,  has lifted the
performance of several asset-manage-ment firms or the asset-management divisions
within  much  larger  financial  services   organizations.   We  believe  growth
possibilities  in Europe remain healthy for these companies given the upsurge in
deregulation and the start of the European Monetary Union in 1999.

     During the market  downturn,  pharma-ceutical  companies  tended to perform
better than many other groups.  Novartis  remains a workhorse within the broader
portfolio and continues to be one of our best-performing stocks. The Swiss

International Growth--Q&A
- --------------------------------------------------------------------------------
                                                                     (Continued)

pharmaceutical  giant  formed by the  merger of  Sandoz  and Ciba has  pro-duced
steady earnings growth and has an attractive  product pipeline.  It continues to
realize cost savings and from the merger.

WHICH SECTORS OR STOCKS DAMPENED PERFORMANCE?

     International  Growth's   worst-perform-ing   sectors  for  the  year  were
electronic  components,   autos  and  auto  parts,  airlines,  energy  services,
chemicals, and exploration companies.

     The energy sector  underperformed  this year as commodity  prices  skidded.
Several  energy-related  companies  were  reduced or  eliminated  when it became
apparent  that oil prices were headed lower with slim  prospects for a near-term
recovery.  Companies  such as  Transocean  Offshore,  British-Borneo  Petroleum,
Woodside  Petroleum and Petroleum  Geo Services  were among  portfolio  holdings
affected by the downturn in energy prices.

     In any  portfolio,  there will be winners  and  losers.  By  following  our
disciplined  style of focusing on companies whose earnings are growing,  we were
able to  minimize  the  damage  from  underperforming  stocks.  Performance  was
hindered  primarily  by companies  that  experienced  earnings  disappointments,
including Shiseido, Alcatel, Electrolux AB and Next PLC.


DID YOU  MAKE ANY  SIGNIFICANT  CHANGES  TO THE  PORTFOLIO  DURING  THE LAST SIX
MONTHS?

     International  Growth  was hard hit  during  the  downturn  because  of its
concentrations  in specific  sectors and regions.  We became somewhat  defensive
when the markets  grew  increasingly  volatile in the summer by  broadening  the
portfolio  accordingly.  When the  environment  began to stabilize,  we added to
positions in some of our longer-term winners, such as Nokia, Novartis, Vodaphone
and Vivendi, all of which moved higher.

     Heading into the  third-quarter  meltdown,  we felt the  portfolio may have
been  overweighted in certain business service and financial stocks. We also had
been too heavily focused in Europe. Consequently,  we broadened the portfolio to
include stocks in sectors or countries not well represented before. For example,
we added Imperial  Tobacco,  a U.K.-based  tobacco company,  and we added to our
position  in Takeda  Chemical,  a  pharmaceutical  firm in Japan.  We also began
selectively  adding  companies  with earnings in turnaround  situations in Asia,
where  we had  only a small  allocation  for  several  quarters  because  of the
region's severe economic problems.  Over the last six months, we felt conditions
were  beginning  to  warrant  a  second  look  at  some  Asian  stocks.  As  the
semiconductor  technology cycle again started to turn positive,  for example, we
added  shares  of  South   Korea-based   Samsung   Electronics  and  Japan-based
semiconductor-manufacturing stocks.

     We feel confident these steps to further  diversify the portfolio will help
continue International Growth's good performance record over the long term.

International Discovery--Q&A
- --------------------------------------------------------------------------------

International Discovery Fund

     An interview with Henrik Strabo,  Mark Kopinski and Brian Brady,  portfolio
managers on the International Discovery investment team

HOW DID  INTERNATIONAL  DISCOVERY PERFORM FOR THE FISCAL YEAR ENDED NOVEMBER 30,
1998?

     International  Discovery posted a very  respectable  14.79%* return for its
fiscal year,  which proved to be one of the most volatile  periods on record for
international  investors.  The fund trailed its  benchmark,  the Morgan  Stanley
Capital International EAFE Index, which gained 16.45%, but performed better than
most of its peers.  According to Lipper, Inc., an independent company that ranks
mutual  funds,  the fund ranked 16th out of the 57  small-company  international
funds  tracked  by Lipper  for the year  ended  November  30,  1998.  The fund's
longer-term  performance  has also  been  strong.  Lipper  ranked  International
Discovery  first out of 19  small-company  international  funds for three  years
ended November 30, 1998.(+)

     One important factor to note is that the EAFE Index is comprised  primarily
of large-capitalization  stocks, whereas International Discovery invests in much
smaller  companies.  As a result,  the fund's  performance  will  frequently  be
different than that of the index.

     Although we use the EAFE as a performance benchmark, we wish to stress that
we employ a bottom-up approach in selecting stocks for International Discovery's
portfolio,  and we do  not  attempt  to  match  or  outperform  any  comparative
benchmark  during short time frames.  Our search for earnings and revenue growth
leads us to fast-growing  companies in a variety of sectors and regions, and our
sector and country  allocations are purely a residual of the individual security
selection  process.  This bottom-up approach helped the fund perform better than
many of its peers.

WHICH FACTORS HAD THE GREATEST INFLUENCE ON PERFORMANCE DURING THE YEAR?

     International  markets were robust  during the first half of  International
Discovery's  fiscal year but unwound  dramatically  in the third quarter of 1998
when the Russian economy collapsed and economic uncertainty in Brazil threatened
to spread  throughout  Latin  America.  The markets were also shaken by the near
collapse of a large global hedge fund,  which sent many investors  scurrying for
safer investment  havens.  Moreover,  small stocks in general suffered more than
their larger counterparts.  This explains, in part, why International  Discovery
underperformed its benchmark. However, in late October, we began to see signs of
stabilization  in  many  markets.  We  believe  we are  well-positioned  to take
advantage of the investment  opportunities the  third-quarter  market correction
has made possible.

WHICH STOCKS OR SECTORS HURT  PERFORMANCE THE MOST?

     Our  holdings  in  Israel,  Sweden  and Japan  dampened  performance.  It's
important to note, however, that

International Discovery--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

International  Discovery's   worst-performing  companies,  for  the  most  part,
suffered as a result of global economic turmoil rather than due to weaknesses in
their fundamental operations or business. The fund's worst-performing stock, for
example, was Admiral,  which is located in the United Kingdom.  Admiral provides
information  technology  systems  and  training  for a broad  range  of  clients
worldwide.  Admiral  is  well-managed  and is known  for  both its  high-quality
products and services and its ability to provide its clients with cost-effective
solutions on time and within  budget.  The  company's  growth has been driven by
robust  spending as corporations  upgrade their computer  systems to become Year
2000-compliant.  However,  market turmoil in the third quarter  raised  investor
concerns  that  in a  financial  crunch,  businesses  would  limit  spending  on
information technology, and the stock fell substantially.

     Elektrim Spolka Akcyjna, a Polish holding, also hurt performance.  However,
in this case, the company's  problems were not connected to Poland's economic or
political situation. Elektrim is a diversified industrial and telecommunications
holding  company that had been enjoying very  dramatic  growth.  The company was
well-positioned    to   benefit    from   the    modernization    of    Poland's
electricity-generating   assets  and   increasing   demand  for   cellular   and
communications  services  in  Europe.  Elektrim's  management  had not  properly
disclosed,  however, that it had entered into a contract in 1996 to sell part of
its stake in a subsidiary,  a cellular  network service called Polska  Telefonia
Cyfrowa (PTC),  for a nominal price.  PTC's market value had increased since the
contract was signed,  and it was worth  substantially  more than the agreed-upon
selling  price.  News  of the  past  agreement  broke  on  Thanksgiving  Day and
Elektrim's stock plummeted 27% in two days.

     On the other hand, JBA Holdings, a London-based computer software supplier,
disappointed  us on an earnings basis.  Although the company's  growth in recent
years has been vigorous, high expenditures on software development collided with
lower-than-expected  sales in the second  quarter,  and its stock price  tumbled
when the company announced  disappointing  earnings.  We removed this stock from
the portfolio.

WHICH STOCKS OR SECTORS ADDED TO PERFORMANCE?

     Our earnings focus led us to several industry  groups,  including banks and
financial services companies and general retailers.  Most of these companies are
located in Europe.

     Banking  and  financial  services  stocks  were  among the  fund's  largest
holdings and were also its top contributors. Pension reform and falling interest
rates across  Europe are changing  Europeans'  attitudes  toward  investing  and
personal   savings.   This   is   resulting   in  a   shift   of   assets   from
low-interest-bearing  savings  accounts to mutual funds and insurance  products.
For example, the top contributor to performance was Marschollek, Lautenschlaeger
und Partner,  a German financial  services  company that added  significantly to
returns in past periods. The company's success is being boosted by growth in its
life insurance and  asset-management  segments.  CGI Group is another example of
success  related to the financial  services  group.  CGI is a large  information
technology  consulting  firm in Canada.  This  company is enjoying  rapid growth
fueled by its recent acquisition of another information  technology firm as well
as by increasing  demand from financial  services  companies eager to streamline
their businesses by outsourcing non-core,  back-office operations. The evolution
taking place in the financial services industry is still

International Discovery--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

in an early  growth  stage,  and we expect this group to continue  demonstrating
outperformance going forward.

     Outside of the financial  services  sector,  we found  excellent  growth in
Galeries  Lafayette,   a  large  retailer  in  France.   Galeries  is  a  sound,
well-managed  operation that is benefiting from the increased  consumer spending
taking place in France.  Corporation  Financiera,  a wine and hotel  business in
Spain,  has also fared well as a result of a pickup in its hotel  operations and
healthy demand for its wines.

WHAT SIGNIFICANT CHANGES DID YOU MAKE TO THE PORTFOLIO IN THE LAST SIX MONTHS?

     The  third-quarter  market  correction gave us an opportunity to re-examine
our industry and country  concentrations.  Many of the faster-growing sectors --
and  consequently  stocks -- in the portfolio were hard hit by the downturn.  We
elected to add to the fastest and most  consistent  growers  and  diversify  the
portfolio  slightly more into Asia,  where we took advantage of some  attractive
restructuring candidates.

     We added  selectively  to Anglo Irish  Bank,  which  concentrates  on niche
banking to middle- and small-sized companies in Ireland. This niche strategy has
benefited from the  extraordinarily  strong growth of the local economy, as well
as the favorable interest rate environment in the European Monetary Union. A new
addition in Asia was Housing and  Commericial  Bank of South Korea.  Housing and
Commercial Bank is led by very progressive and active  management.  The bank was
quick to recognize  and deal with its problem loan  portfolio  and has set sound
standards in order to effect a rapid return to profitability.

HAVE THERE BEEN ANY CHANGES  TO INTERNATIONAL DISCOVERY'S  MANAGEMENT TEAM?

     Yes. Brian Brady was named portfolio  manager.  Brian has focused primarily
on companies with a market  capitalization in Europe, Latin America,  Canada and
Israel.  He joined  American  Century  in 1994 and has  served as an  investment
analyst on the International Discovery team since that time.

WHAT IS YOUR OUTLOOK FOR INTERNATIONAL INVESTING GOING FORWARD?

     Despite the  difficulty  of the last year, we remain very excited about the
long-term  opportunities we see in markets around the world.  Factors at work in
Europe -- including the arrival of American-style  capitalism, the prospect of a
common currency,  a strong economic  recovery and pension  reform--bode well for
investing  there.  We're also seeing  positive  signs of recovery in a number of
emerging  markets.  We believe our bottom-up  approach and earnings growth focus
should  continue to lead us to individual  companies with  excellent  long- term
potential.

Emerging Markets--Q&A
- --------------------------------------------------------------------------------

Mark Kopinski and Michael Donnelly, portfolio managers on the Emerging Markets
Fund

     An interview with Mark Kopinski and Michael Donnelly, portfolio managers on
the Emerging Markets investment team

HOW DID EMERGING MARKETS PERFORM FOR THE YEAR ENDED NOVEMBER 30, 1998?

     The fund persevered in what proved to be an extremely difficult  investment
climate.  Many  emerging  markets  continued to suffer in the wake of the global
economic  problems  in the  second  half of  1998.  Although  Emerging  Markets'
absolute  return for the year was negative,  the fund performed much better than
its benchmark,  the Morgan Stanley  Emerging  Markets Free Index, and many other
emerging   markets   funds.   The  Emerging   Markets  fund  declined   15.90%*,
significantly  less than the 22.42%  decline  posted by the index.  According to
Lipper, Inc. (formerly Lipper Analytical Services),  an independent company that
ranks mutual  funds,  Emerging  Markets was in the top 10% of its peer group for
the year ended November 30,  ranking 13th out of the 152 emerging  markets funds
tracked by Lipper.(+)

WHAT HELPED EMERGING MARKETS PERFORM BETTER THAN ITS BENCHMARK AND PEER GROUP?

     Emerging Markets'  stronger relative  performance was largely the result of
our bottom-up  investment  approach and  disciplined  focus on earnings  growth.
Although we pay  attention  to the economic and  political  factors  affecting a
market sector or a country's fiscal health and stability,  we focus primarily on
company fundamentals in picking stocks for the Emerging Markets portfolio.  This
led us toward  attractive  companies in stable countries and away from countries
and  sectors  of  the  market  that  were  struggling  or  out  of  favor.   Our
stock-specific  process often leads us to names that are not in the index.  This
has been particularly true during the last year. In fact,  several of the fund's
best-performing   holdings   were   not   represented   in  the   index.   These
top-contributing  positions  account  for  much of the  fund's  better  relative
performance.

IN WHICH COUNTRIES AND SECTORS HAVE YOU FOUND THE BEST GROWTH OPPORTUNITIES?

     The global proliferation and spread of information technology is serving as
the catalyst for growth in a number of industries  and regions of the world.  We
discovered  growing  earnings  in  banks,   computer  software  companies,   and
electronic  components   manufacturers  in  many  developing  markets.  This  is
especially true in India, Taiwan, and Singapore, which are home to many computer
software and service companies,  and in Greece and Poland, where banking systems
are coming under  reform.  We've also  continued  to see dramatic  growth in the
cellular and communications services industries. This group has enjoyed nearly a
decade of robust  growth  worldwide,  and is also  continuing to do very well in
many  emerging  markets--particularly  Brazil,  where prices are coming down and
subscriber growth is exploding.

- --------------------------------------------------------------------------------
                                                                    (Continued)

WHICH STOCKS CONTRIBUTED THE MOST TO RETURNS?

     Two of Emerging Markets'  top-performing  stocks,  Wipro Ltd. and Softbank,
are computer software manufacturers whose growth is being driven by their unique
competitive advantages.  Wipro, which we discussed in our semiannual report, has
been a major contributor to returns.  Softbank is a Polish company that provides
software for the Polish financial services industry.

     Until  recently,  Poland's  banking system was much like that in the United
States in the 1970s. The country's telecommunications and information technology
infrastructures  limited its banking  industry to small branch banks.  Now large
regional   banks  are  becoming  more  national  in  scope  and,  with  improved
telecommunications,  are interconnecting their scattered  operations,  which has
resulted in greater need for the types of integrated  software and services that
Softbank provides.

     One distinct  advantage this company has over foreign  software and service
providers  is that it has no  language  barrier to contend  with in Poland.  The
company is also providing software for Poland's pension fund industry,  which is
undergoing reform as well. Poland is in the early stages of both efforts, and we
believe  Softbank  is ideally  positioned  to  benefit  from that  growth  going
forward.

     Another top contributor was MMI Holdings, a small electronics parts company
in Singapore.  It  manufactures  essential  parts for hard disk drives,  and its
largest clients are Japanese computer  manufacturers.  The company is benefiting
from robust  industry  growth and demand for product in the ultra-thin  notebook
segment.

     Chipita was another large holding that performed  well.  Chipita is a Greek
manufacturer of packaged foods. Its core products are packaged croissants, which
are very  popular  across  Europe,  especially  in Spain and  Greece.  Chipita's
management  is very  aggressive  and the company is  expanding  rapidly  through
acquisitions  in other  parts of  Europe.  We are very  pleased  with  Chipita's
performance,  and we believe it has  excellent  potential  for  continued  rapid
growth in earnings and revenues.

WHICH REGIONS OR SECTORS HURT  PERFORMANCE?

     The global  economic  problems  that began in  Southeast  Asia in late 1997
spread to a number of emerging markets,  including Russia and Brazil, and that's
where we felt the most pain. In late August,  Russia  defaulted on its sovereign
debt and,  shortly  thereafter,  Brazil  came  under  pressure  due to  emerging
markets' contagion and real concerns about its fiscal situation.  If there was a
theme or common thread among the fund's underperforming  stocks, it was that, in
nearly  each  case,  the  companies  suffered  due to their  country's  economic
problems rather than any weaknesses in their fundamental operations.

     This was the case  with our  Brazilian  holdings.  Concerns  about  whether
Brazil would have to devalue its currency and how it would address its budgetary
and pension  system  problems  hammered  stock prices across the board,  without
regard to a company's industry,  sector or fundamental health. Telemig is a good
example.  We believed  that the cellular  services  industry  would  continue to
thrive,  but the stock was punished when the country's larger economic  problems
became an issue.  However,  the IMF developed a $40 billion  package to shore up
Brazil in the third  quarter,  and we saw the market  begin to turn  around.  We
stuck to our growth philos-

Emerging Markets--Q&A
- --------------------------------------------------------------------------------
                                                                    (Continued)

ophy  throughout  the  darkest  times,  and  that  enabled  us  to  bounce  back
substantially in October and November.

WHAT CHANGES DID YOU MAKE TO THE PORTFOLIO DURING THE LAST SIX MONTHS?

     We increased  holdings in several  countries in Southeast  Asia,  where the
investing  environment in general has improved as interest rates have come down,
borrowing  costs  have  eased,  and  money is once  again  coming  back into the
economy.  Specifically,  we  increased  weightings  in Thailand and South Korea,
whose governments are changing laws that should encourage and enable healthy and
needed  reform  in those  countries'  financial  systems.  South  Korea  also is
rationalizing  its  corporate  structure  and  making  the  chaebols--their  big
corporate  conglomerates--focus  on core  operations,  which in some cases means
specific  industries.  This  should  reduce  capacity  and  rationalize  several
industries  and, over the long run,  stimulate  growth.  Both countries are also
beginning to benefit from the devaluation of their currencies in 1998.

     On the sell  side,  we reduced  holdings  in  Israel,  particularly  in the
banking sector,  following that country's  interest-rate  hikes. We also reduced
the fund's position in Mexico because we don't  anticipate much near-term growth
there soon, given the country's rather serious  economic  problems.  Money flows
into Mexico are based on commodity  prices,  and oil prices are at a record low.
This does not bode well for stock  prices  going  forward.  We have  limited our
holdings  there to  consumer-based  companies,  such as CIE,  which is  Mexico's
equivalent of Ticket Master here in the United States, and Femsa, a beer company
whose exports are very strong.  We believe these  consumer-based  companies will
continue to demonstrate  growth in earnings  because  consumers in Mexico,  like
those here in the States, are continuing to spend.

WHAT IS YOUR OUTLOOK FOR EMERGING MARKETS?

     We believe the emerging marketplace has changed  dramatically,  and for the
better, over the course of the last year. Not only has the investment  community
of emerging markets learned hard lessons about risk and reward,  but so have the
countries  and  companies  themselves.  The  turmoil  of the last six months has
forced  companies to restructure  their operations and practice better corporate
governance.  A fine example is a large Polish company that had recently  removed
management that deceived  shareholders  after concerted pressure was put on them
to do so. The company's stock price rebounded significantly in response to these
actions. In addition, many excesses have been worked out of the system, and more
rational  thought  processes  appear to be in place.  We will  very  likely  see
investment  decisions  that are based  more on  fundamental  logic  rather  than
excessive, speculative trading driven by unfounded fears.

UNDERSTANDING THE STATEMENTS OF ASSETS AND  LIABILITIES--This  statement details
what the Fund owns (assets),  what it owes (liabilities),  and its net assets as
of the last day of the period.  If you subtract  what the fund owes from what it
owns,  you get the fund's net assets.  For each class of shares,  the net assets
divided  by the total  number of  shares  outstanding  gives you the price of an
individual share, or the net asset value per share.

NET ASSETS are also broken down by capital (money invested by shareholders); net
investment  income not yet paid to  shareholders or net investment  losses;  net
gains earned on investments  but not yet paid to  shareholders  or net losses on
investments (known as realized gains or losses); and finally, gains or losses on
securities  still  owned  by the  fund  (known  as  unrealized  appreciation  or
depreciation).  This  breakdown  tells  you the  value  of net  assets  that are
performance-related,  such as investment  gains or losses,  and the value of net
assets that are not related to performance,  such as shareholder investments and
redemptions.

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     ORGANIZATION -- American Century World Mutual Funds, Inc. (the Corporation)
is  registered  under  the  Investment  Company  Act  of  1940  as  an  open-end
diversified  management investment company.  Three series of funds are currently
issued as  American  Century  -  Twentieth  Century  International  Growth  Fund
(International  Growth),  American  Century -  Twentieth  Century  International
Discovery  Fund  (International  Discovery),  and  American  Century - Twentieth
Century  Emerging  Markets  Fund  (Emerging  Markets)  (the  Funds).  The Funds'
investment  objective is to seek capital growth by investing primarily in equity
securities.  International  Growth seeks to achieve its investment  objective by
investing in securities of issuers in developed markets. International Discovery
seeks to achieve  its  investment  objective  by  investing  in  issuers  having
comparatively smaller market capitalizations.  Emerging Markets seeks to achieve
its investment  objective by investing in issuers in emerging market  countries.
Each Fund is authorized to issue three  classes of shares:  the Investor  Class,
the  Advisor  Class and the  Institutional  Class.  The three  classes of shares
differ  principally in their respective  shareholder  servicing and distribution
expenses and  arrangements.  All shares of each Fund represent an equal pro rata
interest  in the net assets of the class to which such shares  belong,  and have
identical voting, dividend,  liquidation and other rights and the same terms and
conditions,  except for class specific  expenses and exclusive rights to vote on
matters  affecting  only  individual  classes.  Sale of the  Advisor  Class  and
Institutional Class for International  Discovery commenced on April 28, 1998 and
January 2, 1998, respectively. Sale of the Advisor Class and Institutional Class
for Emerging  Markets had not  commenced as of November 30, 1998.  The following
significant  accounting  policies  are in  accordance  with  generally  accepted
accounting principles.

     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.  When valuations are
not readily  available,  securities  are valued at fair value as  determined  in
accordance with procedures adopted by the Board of Directors.

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

     INVESTMENT  INCOME -- 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 accretion of discounts and amortization of premiums.

     FOREIGN  CURRENCY  TRANSACTIONS -- The accounting  records of the Funds are
maintained in U.S. dollars.  All assets and liabilities  initially  expressed in
foreign  currencies  are  translated  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
investment securities,  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 investment
securities  and other  assets  and  liabilities  resulting  from  changes in the
exchange rates.

     Net realized  and  unrealized  foreign  currency  exchange  gains or losses
occurring during the holding period of investment  securities are a component of
realized  gain  (loss)  on  foreign   currency   transactions   and   unrealized
appreciation  (depreciation) on translation of assets and liabilities in foreign
currencies, respectively.

     FORWARD  FOREIGN  CURRENCY  EXCHANGE  CONTRACTS -- The Funds 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 Funds will segregate assets in an amount sufficient to cover their
obligations  under the hedge  contracts.  The net U.S.  dollar  value of foreign
currency  underlying  all  contractual  commitments  held by the  Funds  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 Statements of Assets and Liabilities.  The
Funds bear 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.

     REPURCHASE  AGREEMENTS  -- The Funds may enter into  repurchase  agreements
with institutions that the Funds' investment advisor,

NOVEMBER 30, 1998

     American Century  Investment  Management,  Inc. (ACIM),  has determined are
creditworthy  pursuant  to  criteria  adopted  by the Board of  Directors.  Each
repurchase agreement is recorded at cost. The Funds require that the collateral,
represented by securities,  purchased in a repurchase transaction be transferred
to the  custodian  in a manner  sufficient  to enable the Funds to obtain  those
securities  in the  event of a  default  under the  repurchase  agreement.  ACIM
monitors,  on a daily basis,  the value of the securities  transferred to ensure
the value,  including accrued interest,  of the securities under each repurchase
agreement  is greater  than  amounts  owed to the Funds  under  each  repurchase
agreement.

     JOINT  TRADING  ACCOUNT -- Pursuant  to an  Exemptive  Order  issued by the
Securities  and  Exchange  Commission,  each Fund along  with  other  registered
investment  companies  having  management  agreements  with 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 or Agency obligations.

     INCOME TAX STATUS -- It is the  policy of the Funds 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
income taxes.


     DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded
on the  ex-dividend  date.  Distributions  from net  investment  income  and 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  reflect the differing character
of certain income items and net capital gains and losses for financial statement
and tax  purposes  and may  result in  reclassification  among  certain  capital
accounts.

     On December  18, 1998,  International  Growth and  International  Discovery
declared and paid a  distribution  to  shareholders  of record on that date. The
distributions  from net investment income in International  Growth were $0.0166,
$0.0045,  and $0.0374 for the  Investor,  Advisor,  and  Institutional  Classes,
respectively. The distribution from net realized gain on investments was $0.1445
for all classes of International Growth. The distribution from net realized gain
on investments was $0.0343 for all classes of International Discovery.

     At November 30, 1998, Emerging Markets had accumulated net realized capital
loss carryovers for federal income tax purposes of $6,440,968  (expiring in 2005
through 2006) which may be used to offset future taxable gains.

     ADDITIONAL   INFORMATION   --  Funds   Distributor,   Inc.   (FDI)  is  the
Corporation's  distributor.  Certain  officers  of FDI are also  officers of the
Corporation.

2. TRANSACTIONS WITH RELATED PARTIES

     The  Corporation  has entered  into  Management  Agreements  with ACIM that
provide each Fund with investment  advisory and management  services in exchange
for a single,  unified management fee per class. The Agreements provide that all
expenses of the Funds, except brokerage commissions,  taxes, interest,  expenses
of those directors who are not considered "interested persons" as defined in the
Investment  Company  Act of 1940  (including  counsel  fees)  and  extraordinary
expenses, will be paid by ACIM. The fee is computed daily and paid monthly based
on each class's average daily closing net assets during the previous month.

   The  annual  management  fee for each  class of  International  Growth  is as
follows:

     The Board of Directors  has adopted the Advisor  Class Master  Distribution
and  Shareholder  Services  Plan  (the  Plan),  pursuant  to Rule  12b-1  of the
Investment  Company Act of 1940.  The Plan provides that the Funds will pay ACIM
an annual  distribution  fee equal to 0.25% and service fee equal to 0.25%.  The
fees are computed  daily and paid monthly based on the Advisor  Class's  average
daily  closing  net assets  during the  previous  month.  The  distribution  fee
provides   compensation   for  distribution   expenses   incurred  by  financial
intermediaries  in  connection  with  distributing  shares of the Advisor  Class
including,  but not limited to,  payments to  brokers,  dealers,  and  financial
institutions  that have entered into sales  agreements with respect to shares of
the  Funds.   The  service  fee  provides   compensation   for  shareholder  and
administrative  services  rendered by ACIM, its affiliates or independent  third
party  providers.  Fees incurred under the Plan during the period ended November
30,  1998,  were  $72,610  and $32 for  International  Growth and  International

Independent Auditors' Report
- --------------------------------------------------------------------------------

The Board of Directors and Shareholders,
American Century Mutual Funds, Inc:

   We have  audited  the  accompanying  statements  of assets  and  liabilities,
including the schedules of investments,  of American Century - Twentieth Century
International  Growth Fund,  American Century - Twentieth Century  International
Discovery Fund and American  Century - Twentieth  Century  Emerging Markets Fund
(the  "Funds"),  comprising  American  Century World Mutual  Funds,  Inc., as of
November 30, 1998,  and the related  statements of operations  for the year then
ended,  the  statements  of changes in net assets for each of the two periods in
the period then ended, and the financial  highlights for the periods  presented.
These financial  statements and the financial  highlights are the responsibility
of the Funds'  management.  Our responsibility is to express an opinion on these
financial statements and the 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 the 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 at November
30, 1998 by  correspondence  with the custodian and brokers;  where replies were
not received from brokers, we performed other auditing procedures. 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,  such financial  statements and financial  highlights present
fairly, in all material  respects,  the financial  positions of American Century
Twentieth  Century  International  Growth  Fund,  American  Century -  Twentieth
Century  International  Discovery Fund and American Century - Twentieth  Century
Emerging  Markets Fund as of November 30, 1998, the results of their  operations
for the year then  ended,  the  changes  in their net assets for each of the two
periods  in the  period  then  ended,  and  the  financial  highlights  for  the
respective  stated  periods in conformity  with  generally  accepted  accounting
principles.

Share Class and Retirement Account Information
- --------------------------------------------------------------------------------

SHARE CLASSES

     Three  classes of shares  are  authorized  for sale by the funds:  INVESTOR
CLASS,  ADVISOR CLASS, and INSTITUTIONAL  CLASS.  INVESTOR CLASS shareholders do
not pay any  commissions or other fees for purchase of fund shares directly from
American   Century.   Investors  who  buy  Investor   Class  shares   through  a
broker-dealer  may be required to pay the  broker-dealer a transaction  fee. THE
PRICE AND PERFORMANCE OF THE INVESTOR CLASS SHARES ARE LISTED IN NEWSPAPERS.  NO
OTHER CLASS IS CURRENTLY LISTED.

     ADVISOR  CLASS shares are sold  through  banks,  broker-dealers,  insurance
companies  and financial  advisors.  Advisor Class shares are subject to a 0.50%
Rule 12b-1  service and  distribution  fee. Half of that fee is available to pay
for recordkeeping and administrative  services, and half is available to pay for
distribution  services provided by the financial  intermediary through which the
Advisor Class shares are purchased. The total expense ratio of the Advisor Class
shares  is 0.25%  higher  than the total  expense  ratio of the  Investor  Class
shares.

     INSTITUTIONAL  CLASS  shares  are  available  to  endowments,  foundations,
defined  benefit  pension  plans  or  financial   intermediaries  serving  these
investors.   This  class   recognizes  the  relatively  lower  cost  of  serving
institutional customers and others who invest at least $5 million in an American
Century fund or at least $10 million in multiple  funds.  In  recognition of the
larger  investments and account  balances and  comparatively  lower  transaction
costs, the total expense ratio of the  Institutional  Class shares is 0.20% less
than the total expense ratio of the Investor Class shares.

     The Advisor and  Institutional  Classes of shares for Emerging  Markets had
not commenced as of November 30, 1998.

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

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)
account] 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 AND POLICIES

     The  Twentieth  Century  Group  offers 11 equity  funds that  invest in the
stocks of growing  companies,  both  domestically and  internationally,  using a
growth  investment  strategy  developed  by American  Century.  This  philosophy
focuses on three important  principles.  Ideally, we seek to own companies whose
earnings  and  revenues  are not only  growing,  but  growing at a  successfully
faster,  or  accelerating  pace.  Second,  we  attempt  to keep the funds  fully
invested,  regardless of short-term  market activity.  Experience has shown that
market  gains  can  occur  in  unpredictable   spurts  and  that  missing  those
opportunities can  significantly  limit the potential for gain. Third, the funds
are managed by teams,  rather than by one "star" manager. We believe this allows
us to make better, more consistent management decisions.

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

     INTERNATIONAL  GROWTH invests primarily in the equity securities of foreign
companies. These companies will be located primarily in developed countries.

     INTERNATIONAL  DISCOVERY  invests  primarily  in the equity  securities  of
smaller foreign companies.  Smaller foreign companies are considered to be those
that have at the time of  investment  a market  capitalization  of less than the
U.S. $1.5 billion or less than U.S. $500 million in freely tradable  securities.
The fund may experience greater share price fluctuation and short-term risk than
International Growth.

     EMERGING MARKETS invests primarily in the equity securities of companies in
emerging market countries. The companies may be located or principally traded in
emerging market  countries,  and also may derive a significant  portion of their
business from emerging market countries.  This fund may experience greater share
price  fluctuation  and  short-term  risk than  either  International  Growth or
International Discovery.

     International   investing  involves  special  risks,   including  political
instability  and economic  risk.  Investing in emerging  markets may  accentuate
these  risks.  Historically,  share  prices  of small  companies  have been more
volatile than those of large companies.


HOW CURRENCY RETURNS AFFECT  FUND PERFORMANCE

     For U.S. investors, the total return from international stocks includes the
effects of currency  fluctuations--the movement of international currency values
in relation to the value of the U.S. dollar.  Currency  exchange rates come into
play when international stock income, gains and losses are converted into U.S.
dollars.

     Changing currency values may have a significant impact on the total returns
of  international  stock  funds.  The value of the foreign  investments  held by
international  stock  funds may be reduced or  increased  by changes in currency
exchange  rates. As a result,  the value of your  investment  could change based
solely upon changes in the exchange  rates between  foreign  currencies  and the
U.S. dollar. The dollar value of a foreign security generally decreases when the
value of the dollar rises against the foreign  currency in which the security is
denominated. (The weakened foreign currency buys fewer dollars.) Conversely, the
dollar  value of a  foreign  security  tends to  increase  when the value of the
dollar falls against the foreign  currency.  (The stronger foreign currency buys
more  dollars.) In addition,  the value of fund assets may be affected by losses
and other expenses incurred in converting between various currencies in order to
purchase  and sell foreign  securities  and by currency  restrictions,  exchange
control regulations, currency devaluations and political developments.

COMPARATIVE INDICES

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

     MORGAN STANLEY CAPITAL  INTERNATIONAL  (MSCI) has developed several indices
that measure the  performance  of foreign stock  markets.  The best known is the
EUROPE, AUSTRALASIA,  FAR EAST INDEX (EAFE(reg.tm)),  which is a widely followed
group of stocks from 20 countries.  Within this index are two narrower  indices,
MSCI EUROPE and MSCI FAR EAST,  which measure stock  performance  in 14 European
countries and four Asian countries, respectively.

     The MORGAN STANLEY EMERGING MARKETS FREE INDEX (EMF(reg.tm)) represents the
performance of stocks in 26 emerging market  countries in Europe,  Latin America
and the Pacific Basin.

Glossary
- --------------------------------------------------------------------------------

RETURNS

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

* AVERAGE ANNUAL RETURNS  illustrate the annually  compounded returns that would
have produced the fund's cumulative total returns if the fund's  performance had
been  constant  over the  entire  period.  Average  annual  returns  smooth  out
variations  in a fund's  return;  they are not the same as  fiscal  year-by-year
results.  For fiscal year-by-year total returns,  please refer to the "Financial
Highlights" on pages 39-45.

INVESTMENT TERMS

* 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.)

* MEDIAN MARKET CAPITALIZATION-- Market capitalization (market cap) is the total
value of a  company's  stock and is  calculated  by  multiplying  the  number of
outstanding  common shares by the current share price.  The company whose market
cap is in the  middle  of the  portfolio  is the  median  market  cap.  Half the
companies in the portfolio  have values  greater than the median,  and half have
values that are less. If there is an even number of  companies,  then the median
is the average of the two companies in the middle.

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

* PORTFOLIO  TURNOVER-- the percentage of a fund's investment  portfolio that is
replaced during a given time period, usually a year. Actively managed portfolios
tend to have higher  turnover than passively  managed  portfolios  such as index
funds.

TYPES OF STOCKS

* CYCLICAL STOCKS--  generally  considered to be stocks whose price and earnings
fluctuations  tend to follow the ups and downs of the business  cycle.  Examples
include the stocks of  automobile  manufacturers,  steel  producers  and textile
operators.

* GROWTH  STOCKS--  stocks  of  companies  that have  experienced  above-average
earnings  growth and are expected to continue  such  growth.  These stocks often
sell at  high  P/E  ratios.  Examples  can  include  the  stocks  of  high-tech,
healthcare and consumer staples companies.

* LARGE-CAPITALIZATION  ("LARGE-CAP") STOCKS-- generally considered to be stocks
of  companies  with a market  capitalization  (the  total  value of a  company's
outstanding  stock) of more than $5  billion.  These tend to be the stocks  that
make up the Dow Jones Industrial Average and the S&P 500.

* MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS--generally considered to be stocks of
companies  with  a  market  capitalization  (the  total  value  of  a  company's
outstanding  stock) of between $1 billion and $5  billion.  These tend to be the
