Y2K TESTING EFFORTS PAY  DIVIDENDS IN PREPAREDNESS
- --------------------------------------------------------------------------------

Y2K, short for the year 2000,  refers more  specifically to the date change from
December  31,  1999 to January  1, 2000.  This date  change is  significant  for
computers  because  many  were  originally  programmed  to  process  dates  with
two-character years -- 99 instead of 1999.

When the  calendar  rolls  to  2000,  this can  create  problems  for  computers
programmed  this way because they will read the date as "00," and may  interpret
it as 1900. Most companies have been working to reprogram their computer systems
with  four-digit  years.  Reprogramming  is very  labor-intensive  and  requires
testing  to ensure  that  there  are no  errors  and that all lines of code were
successfully changed.

Recognizing  the possible  impact of the Y2K issue,  our  senior-level  Steering
Committee,  programmers,  business  partners  and Y2K  team  have  been  working
diligently to make January 1, 2000 a non-event for American Century investors.

Currently,  all of our computer systems have been modified,  tested and returned
to  production.  We have an ongoing  commitment  to testing our systems with our
vendors and business partners and within the industry throughout the rest of the
year.

In March  and April of this  year,  we  participated  in the  Security  Industry
Association's (SIA) industry-wide test and successfully  processed  transactions
for dates up to and beyond 2000. American Century  transactions with our partner
firms were processed free of Y2K bugs. We also  participated  in the Market Data
Test conducted by the SIA and Financial  Information  Forum in May.  Again,  the
computer scripts were executed successfully with no Y2K-related errors.

In addition  to our testing  schedule,  our Y2K team has  developed  contingency
plans.  These  plans  will  minimize  the  impact on our  investors  and help us
maintain operations in the event of any Y2K-related  incidents.  We will conduct
practice  drills of  contingency  scenarios  during  the rest of 1999 and refine
those  plans to respond  quickly and  effectively  so that the date change is as
seamless as possible  for  investors.  We expect the year 2000 to be business as
usual at American Century.

MINIMIZE YOUR MUTUAL FUND TAX HIT

      American Century's newest equity fund,  Tax-Managed Value, is designed for
      long-term  growth and to minimize the tax hit you take on your mutual fund
      investments  each year. The fund is managed to keep taxable  distributions
      to a minimum by using the following strategies:

      * BUY AND HOLD --Low portfolio turnover helps limit realized capital gains
      and takes advantage of long-term capital gains tax rates.

      * OFFSET GAINS --When gains are realized in the portfolio, they are offset
      with  capital  losses  from  securities  sold in that tax  year or  losses
      carried over from previous years.

      * SELL HIGHER-COST  SHARES FIRST --Selling shares that cost the most first
      helps minimize the taxable gains incurred from a sale.

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

     The six months ended May 31, 1999, saw investment  capital leave Europe and
move to developing  economies,  particularly in Asia,  Russia and Latin America,
amid  signs  that  those  regions  might be in the early  stages of an  economic
recovery.  Emerging markets, which were hardest hit by the economic slowdown and
resulting  financial crises that began in fall 1997, appeared to be poised for a
snap-back.  At present, we believe growth companies in these regions are selling
at very attractive prices.

     Against this backdrop,  American  Century's quartet of international  funds
turned in strong results.  The International  Discovery,  Emerging Markets,  and
Global Growth funds posted double-digit returns. Although International Growth's
results  trailed  those of its sister  funds,  the fund still  outperformed  its
benchmark, and its long-term returns remain very robust.

     We are especially  pleased with the  performance of our newest global fund,
Global  Growth,  which was  introduced  on December 1. As a global fund,  Global
Growth has no geographical  restraints and can invest anywhere in the world. The
fund's ability to capitalize on the success of U.S. companies powered its return
for the period.

     On the corporate front, our focus continues to be on making it easier to do
business with us and on helping investors reach their financial goals. In March,
we  consolidated  all our funds under the American  Century name. We believe the
American Century nameplate makes it simpler for you to identify your funds.

     We  have  also  reclassified  our  entire  family  of 71  funds,  based  on
investment  goals and risk levels,  so you can more easily choose the funds that
are right for you. A complete list of American  Century funds  arranged by their
new classifications is on the inside back cover of this report.

     We also continue to expand the American  Century  international  investment
team,  which has doubled over the past three  years.  Our  portfolio  teams have
excellent depth, with an array of experienced  managers and analysts.  We remain
committed to building and maintaining a talented management group.

     Finally, we redesigned and enhanced our Web site,  www.americancentury.com.
There you'll find daily fund information,  including price and performance data,
market and national news,  and a forms center with access to the  most-requested
investor  forms  and  applications.  You  can  also  sign  up  to  receive  fund
prospectuses and shareholder reports electronically.

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

Sincerely,

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

MARKET PERSPECTIVE

*  For the six months ended May 31, 1999,  the  once-moribund  economies of Asia
   and Latin America outpaced Europe, whose economies showed signs of slowing.

*  Europe was  negatively  impacted by the euro's swoon.  The euro was hurt by a
   sluggish  Germany,  declining  European interest rates, and a flight of money
   from European growth stocks to cyclical and commodity  stocks,  as well as to
   Asia and Latin America.

*  The  outlook  for Europe  remains  bright  because  corporate  restructurings
   continue at a rapid pace.

*  Asia,  especially South Korea and Singapore,  was bolstered by lower interest
   rates, reduced debt, and export-driven growth; even Japan began a turnaround.

*  Mexico's  resurgence was fueled by higher oil prices,  lower interest  rates,
   and a robust U.S. economy. Brazil rebounded after the government devalued the
   real.

INTERNATIONAL GROWTH

*  International Growth's Investor Class shares had a healthy return for the six
   months  and   outperformed   its  benchmark,   the  Morgan  Stanley   Capital
   International EAFE Index.

*  International  Growth's top contributors were  technology-related  companies,
   including    telecommunications    firms--cellular   service   and   cellular
   communications equipment providers.

*  Holdings in pharmaceutical companies dampened performance,  as did the fund's
   stake in banks, automobiles and auto parts manufacturers.

INTERNATIONAL DISCOVERY

*  International  Discovery posted impressive gains, and outpaced its benchmark.
   The decision not to sell several strong growth stocks in the third quarter of
   1998 was rewarded when the markets roared back.

*  Fund  performance  was boosted by the dynamic  performance  of several  Asian
   economies, including South Korea, Singapore, and Japan.

*  Telephone   communications,   contract  manufacturers  and  cable  television
   operators  were  among  the  fund's   largest   holdings  and  also  its  top
   contributors to performance.

EMERGING MARKETS

*  Emerging  Markets  had a strong  return and  outperformed  its  benchmark  as
   emerging markets roared back.

*  Fund  returns  were boosted by strong  earnings  growth in  companies  from a
   variety of sectors in South Korea, Singapore, Mexico and India.

*  Holdings in banks, telecommunications, and electronic component manufacturers
   in many developing markets helped performance.

GLOBAL GROWTH

*  Global Growth opened  December 1, 1998,  and performed  well during its first
   months in operation.  It's life-of-fund  return as of May 31, 1999,  compares
   favorably to the gain posted by its benchmark, the MSCI World Free Index.

*  Global Growth's 50% stake in fast-growing U.S. companies helped  performance.
   U.S.  holdings  that  contributed  the  most to  results  were  found  in the
   telecommunications, Internet, media and pharmaceutical industries. In Europe,
   telecommunications  companies,  retailers,  and financial  services companies
   added to returns.

Market Perspective from Henrik Strabo
- --------------------------------------------------------------------------------

[photo of Henrik Strabo]
Henrik Strabo, Chief Investment Officer of  international investments at
American Century

ASSETS EXIT EUROPE

     The most significant  dynamic affecting the  international  markets for the
six months ended May 31, 1999, was the dramatic exodus of investment  assets out
of Europe and into Japan and the emerging  markets of  Southeast  Asia and Latin
America.  Perhaps  the most  important  cause of this  rapid  migration  was the
less-than-successful  launch of the euro,  the new  currency of the Economic and
Monetary  Union (EMU).  The euro  faltered  when EMU  economies  showed signs of
slowing.  Germany,  which  accounts for  one-third  of EMU output,  is currently
growing at less than 2%  annually,  and,  with the  exception  of Italy,  is the
Union's least impressive  growth story.  European  interest rates also declined,
further  undermining  the euro,  which had to compete  with rising  rates in the
U.S., where the economic boom continued  virtually unabated.  Finally,  fears of
returning  global  inflation led to a flight from growth stocks to  economically
sensitive  cyclical  and  commodity  stocks--and  to the  recovering  markets of
emerging Asia and Latin America.

REGIONS ON THE MEND

     Inflation  concerns  and the  subsequent  flight  from  growth  stocks were
largely driven by the turnaround in Asia and Latin America.  As these  economies
bottomed out,  investors  feared that their revival would cause increased global
demand for  commodities  and  infrastructure--resulting  in higher  prices.  The
initial  beneficiaries of economic rebounds are usually the commodity  producers
and heavy industrials, traditional value stocks.

     In Asia,  South  Korea and  Singapore  both  strengthened,  helped by lower
interest rates. South Korean businesses rebounded via export-led growth, a lower
overall  cost  structure  and a  reduction  of heavy debt  burdens.  In the more
developed economy of Singapore,  which did not suffer from many of the financial
excesses of its neighbors,  export growth-- namely in  electronics--was  robust.
Even  Japan,  after years of economic  stagnation,  was on the mend.  Foreigners
recognized  the  Japanese  recovery  early in the  year.  Foreign  purchases  of
Japanese shares hit record volumes during the first calendar quarter of 1999.

     In Latin  America,  Mexico  surged  ahead,  helped along by the rise in oil
prices, lower interest rates, and the strong pull of the resilient U.S. economy.
Brazilian financial markets also rebounded sharply after the government devalued
the real. Brazil  drastically  reduced interest rates, and stepped back from the
brink of  financial  collapse  to an  equilibrium  that the equity  markets  are
rewarding.

A HEALTHY GLOBAL ECONOMY

     The current global economy gives  investors  many more  opportunities  from
which to choose.  Temporary  setbacks  aside,  many  constructive  trends are in
place,  especially  in Europe,  where  corporate  restructurings  continue  at a
phenomenal pace. In the long run, the euro should act as a catalyst for Europe's
burgeoning  American-style  equity  culture  and  encourage  the  growth  of the
Continent's capital markets.

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

[photo of Mark Kopinski and Henrik Strabo]

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

HOW DID INTERNATIONAL GROWTH PERFORM DURING THE FIRST HALF OF ITS FISCAL YEAR?

     International  Growth  posted a healthy  7.03%*  return  for the six months
ended May 31, 1999. It  outperformed  its benchmark,  the Morgan Stanley Capital
International EAFE Index (EAFE),  which gained 4.01%.  International Growth also
outpaced most foreign stock funds.  According to Lipper,  a mutual fund research
firm, the average international fund returned 4.98% for the period.

WHAT WERE THE MAJOR FACTORS INFLUENCING INTERNATIONAL GROWTH'S PERFORMANCE?

     Perhaps the dominant factor was the reallocation of investment  assets away
from  Europe  and into Asia and Latin  America.  In both  Europe  and the United
States, investors also shifted away from the high-priced growth stocks that have
been in favor for the last few years and put money in value-oriented or cyclical
stocks.  This market  rotation was  particularly  pronounced  on the  Continent.
Although much of Europe showed excellent  promise  throughout most of last year,
growth tapered off significantly in early 1999, and that impacted  International
Growth's performance.

     In Japan,  large  capitalization  stocks  demonstrated  some early signs of
recovery during the first quarter of 1999. The  restructuring bug seemed to bite
many companies and there were flurries of  announcements.  We remained  somewhat
cautious, treating many of these announcements with a healthy skepticism. We did
identify a few growth and  restructuring  strategies that were credible,  but on
the  whole  International  Growth  entered  the  period  underweighted  in Japan
relative to its benchmark  index, and therefore was unable to benefit fully from
the  Japanese  resurgence.  We  continue  to conduct  fundamental  research on a
company-by-company  basis in  Japan  and will  add  exposure  to firms  that are
repositioning themselves for significant future growth.

WHICH INDUSTRIES OR STOCKS CONTRIBUTED THE MOST TO RETURNS?

     Almost without  exception,  International  Growth's top  contributors  were
technology-related  companies,  including telecommunications firms, and cellular
service and  cellular  communications  equipment  providers.  Telecommunications
companies  represented  the largest  sector  weighting.  As the major  broadband
carriers  of  electronic  data,   telecommunication   companies  have  benefited
enormously  from  increasing  Internet and data traffic.  In the United Kingdom,
telecommunications  giant Colt  Telecom  Group,  one of the largest  competitive
local exchange network carriers in Europe, was the fund's best-performing stock.
Colt carries data for many  financial  service  firms and recently  underwent an
aggressive   expansion  campaign  that  resulted  in  greatly  increased  market
penetration.  Six  months  ago,  Colt was  operating  in six  competitive  local
exchange networks in three European countries; it now

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

operates in 13 networks in eight European countries.

     Mannesman AG, International  Growth's largest holding,  also benefited from
growth  in  the  cellular   telecommunications  arena.  Mannesman  is  a  German
engineering firm that has rebuilt itself into a  telecommunications  powerhouse,
offering  both  cellular and data  services.  The company,  known mostly for its
cellular service network in Germany, continues to expand its pan-European reach,
either through acquisition or by establishing  strategic alliances.  It has also
aggressively  grown  its  electronic   commerce  services  and  high-speed  data
communications  division.  Mannesman's  telecommunications unit grew over 30% in
the first four months of 1999.

WHAT OTHER COMMUNICATIONS FIRMS  CONTRIBUTED TO RESULTS DURING THE  SIX MONTHS?

     Nokia, a Finnish company that develops and  manufactures  mobile phones and
systems for cellular  networks  worldwide,  and Vodafone  Group plc, the largest
mobile  telecommunications  service provider in Britain,  added significantly to
returns.  Nokia's net  revenues  jumped 55% in the first  quarter of 1999 alone,
driven in part by aggressive  sales in Europe,  the United States,  and parts of
Asia, where demand for Nokia's innovative  wireless  communication  handsets and
telecom  infrastructure  equipment  has been robust.  Vodafone has enjoyed rapid
growth  in the  United  Kingdom,  its home  market,  and  also  internationally,
particularly in the Netherlands, France and Germany. Vodafone recently announced
it would merge with Airtouch  Communications  (another fund holding). The merger
will give  Vodafone  access to the U.S.  wireless  market  and add an  extremely
important piece as the company  expands into a global  wireless  network leader.
News of the proposed merger lifted stock prices for both Vodafone and Airtouch.

WHAT WERE SOME OF THE OTHER SECTORS OR INDUSTRIES THAT PERFORMED WELL?

     Outside of the technology sector,  industrial  machinery  manufacturers and
European  retailers turned in strong  performances.  An example of the former is
Sidel,  which  makes  machinery  and molds  for the  production  of  specialized
polyethylene (plastic) containers for carbonated beverages,  water, oil, juices,
alcohol, and detergents.  Sidel's sales have been robust in the United States as
well as in markets in Asia and, to a lesser degree,  South America.  The company
recently developed new machinery that significantly lowers raw material cost and
can also be used for making  plastic  bottles for beer.  Sidel  stands to profit
nicely on the sale of its  machinery,  and, in an innovative  marketing  effort,
will also garner a percentage on each bottled beverage sold.

     Hennes  &  Mauritz,  a  European  clothing  retailer,  is one  of the  most
successful  chains in Europe.  It has a similar profile to the Gap in the United
States.  The company  possesses a  phenomenal  track  record,  continues to grow
aggressively,  and consistently beats earnings estimates.  The stock contributed
significantly to returns and we increased the position as earnings  continued to
rise.

WHICH SECTORS OR HOLDINGS WERE  DISAPPOINTING DURING THE FIRST HALF?

     International Growth's three worst performing sectors were pharmaceuticals,
banks, and auto and auto parts manufacturers.  However,  problems in these areas
were stock- or company- specific rather than the result of fundamental  industry
weakness.

     At the beginning of the period, pharmaceutical companies represented just

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

over 5% of investments. Novartis was one of the largest holdings in the fund for
quite  some  time,  but we began to cut our  weighting  in  response  to slowing
growth. Another significant  pharmaceutical/foods  holding,  Unilever,  dampened
returns due to sluggish growth in its main European markets.

     A  disappointment  within the banking  and  financial  services  sector was
Newcourt Credit Group, a Toronto-based business lender that originates, manages,
and sells asset-based loans (loans backed by assets such as commercial buildings
or  property).  The  company  was  preparing  to be  acquired  by CIT Group in a
proposed  $4.12  billion  takeover.  However,  unexpectedly  poor  first-quarter
earnings raised the possibility that the merger would not be completed, and that
took the stock  down.  We began to reduce our  position  in  September  1998 and
completely eliminated the stock during the first quarter of 1999.

     Volkswagen  was  disappointing  as well.  This is a  classic  example  of a
company whose good product doesn't translate into a strong stock price. Although
the VW's  automobile  models are very  popular  in the  United  States and other
markets,  the stock has suffered  from a lack of  management  credibility  after
executives  issued a statement warning of a looming crisis in global auto demand
and sales.

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

     In   terms   of   geographical    changes,   we   increased   holdings   in
Asia--particularly  Singapore and  Korea--where  earnings growth has accelerated
and we believe  the  potential  for  further  growth is strong.  We added to our
Japanese holdings somewhat;  however,  that increase was primarily the result of
augmenting the position in Sony,  which has  demonstrated  a firm  commitment to
restructure  its  business.  We built a small  position  in  Mexico,  which is a
petroleum exporter, and whose economy was helped along by the rise in oil prices
and by the resolution of problems in the country's  banking  infrastructure.  We
also  beefed up our stake in Hong Kong and  slightly  trimmed  holdings  in both
Germany and France.

     Our  largest  industry  shift was in  pharmaceuticals,  which we  discussed
earlier.  We shaved our stake in food and beverage  companies as  well--earnings
have tapered off in recent  months--and  in retail grocery  stores,  an industry
that has also suffered a general slowdown.

WHAT IS YOUR OUTLOOK FOR INTERNATIONAL INVESTING IN THE SECOND HALF OF THE YEAR?

     We are bullish on the long-term  opportunities we're seeing in many foreign
markets.   Europe   continues   to  benefit   from   privatizations,   corporate
restructurings, the introduction of a common currency (the euro), and structural
changes in European  economies.  Signs of recovery in Asia are also encouraging.
Since we believe this to be the very early  stages of the rebound,  we're adding
investments there very selectively. Japan must continue to move forward and show
significant  progress in  restructuring  in order not to impede  recovery in the
rest of Asia.  Regardless of regional issues, we believe our bottom-up  approach
and earnings growth focus should continue to lead us toward  companies with good
long-term potential.

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

[photo of Brian Brady, Henrik Strabo and Mark Kopinski]

     An interview  with Brian Brady (left),  Henrik  Strabo,  and Mark Kopinski,
portfolio managers on the International Discovery team.

HOW DID THE FUND PERFORM FOR THE SIX MONTHS ENDED MAY 31, 1999?

     International  Discovery posted a very healthy 16.23%* return,  compared to
the much  smaller  4.01% posted by its  benchmark,  the Morgan  Stanley  Capital
International EAFE Index.

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

WHICH FACTORS HAD THE GREATEST IMPACT ON PERFORMANCE OVER THE LAST SIX MONTHS?

     Our  decision  not to sell  several  strong  growth  companies  during  the
tumultuous  third  quarter of 1998  --which  was roiled by global  upheaval--was
rewarded after the Federal Reserve  lowered  interest rates three times later in
the  year.  These  growth  companies  were the first to roar back when the world
economy began to stabilize and improve later in the year. We also began to see a
turnaround in the fundamentals of companies in Asia and increased our weightings
there.  Since we invest in  smaller  capitalization  companies  that are  highly
dependent   on   local   economies--few    small-cap   names   are   world-class
exporters--it's crucial that we ascertain the strength of local demand before we
invest in a company. Holdings were increased in South Korea, Singapore, and even
Japan, whose specialty retail sector showed the first signs of recovery.

     After  the Asian  financial  meltdown  in 1997,  Korea was one of the first
countries to focus on restructuring its economy. We saw statistical  evidence of
this  restructuring  as  Korea's  industrial  productivity  picked  up  and  the
country's interest rates began declining.  Although corporate Korea, as a whole,
has yet to fully embrace significant reform, small- and medium-sized  businesses
have been the first to restructure and create new growth.

     We found  opportunities  in Singapore as well,  where lower  interest rates
gave a boost to the interest  rate-sensitive  financial services and real estate
sectors.  Singapore also has a number of high-quality,  high-tech companies such
as Datacraft Asia Ltd. and Natsteel Electronics.

     We started to see a slowdown in European  earnings  growth,  especially  in
Germany,  and we  reduced  some of our  holdings.  International-Mueller  NV and
Sartorius AG are companies that posted slower growth.  However, more than 53% of
the fund is still invested in European growth stocks.

WERE THERE SPECIFIC INVESTMENT THEMES THAT PROPELLED THE BEST PERFORMING STOCKS
OR SECTORS?

     Since the European telecommunications industry was deregulated in 1998, the
sector has attracted several entrepreneurial companies, which have spent

"SINCE WE INVEST IN SMALLER  CAPITALIZATION  COMPANIES THAT ARE HIGHLY DEPENDENT
ON LOCAL ECONOMIES-- FEW SMALL-CAP NAMES ARE WORLD-CLASS EXPORTERS--IT'S CRUCIAL
THAT WE ALSO  ASCERTAIN  THE  STRENGTH  OF LOCAL  DEMAND  BEFORE  WE INVEST IN A
COMPANY."

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

the last few  years  investing  in the  requisite  hardware  and  optical  fiber
networks.  This is  enabling  them to compete  directly  with the old  telephone
monopolies,  such as Deutsche Telekom AG. Three fund holdings--Viatel,  Omnicom,
and  Global  TeleSystems--are  now  offering  voice  and data  services  at very
competitive prices in rapidly expanding markets.  Growing Internet usage is also
helping to further expand demand for these services. Our top performer,  Viatel,
has one of the largest  pan-European data networks.  The company's  fortunes are
growing as evidenced by revenues  which rose 190% to $61.6  million in the first
quarter of 1999.

     Another theme  boosting sales and earnings among our holdings is the effort
of  major   corporations  to  reduce  costs  by  outsourcing   manufacturing  of
telecommunications  and electronic components to contract  manufacturers such as
Canadian-based Celestica and Singapore-based Natsteel Electronics.  After a firm
designs a high-tech  product,  it often  subcontracts  the  manufacturing  to an
outsourcing  company that can achieve  economies of scale by building  parts for
many  companies,  and that in turn,  lowers the  product's  cost.  For  example,
Celestica   recently  was  selected  to  provide  most  of  Cabletron   Systems'
electronics  manufacturing.  Cabletron  is a  provider  of  computer  networking
solutions  to  companies  worldwide.  On  the  strength  of  new  contracts  and
acquisitions,  Celestica's  first  quarter  sales  jumped 46% to $1.08  billion.
Outsourcing  also is driving sales and earnings at India-based  Satyam  Computer
Services,  which does  computer  programming  and Y2K computer  glitch fixes for
companies around the globe.

     Another  theme that  contributed  to returns was the  expanding  market for
cable television. Cable television operators in Europe now realize that they can
upgrade their existing networks to offer customers additional services,  such as
Internet  and  local  and  long-distance  telephone  services.  One of our  best
performers,  United  International  Holdings,  owns several  cable and telephone
companies worldwide. One of its subsidiaries,  publicly traded UPC, operates the
largest  group of  cable  networks  in  Europe.  These  networks  provide  cable
television,  phone service, high-speed Internet access, and programming services
in 10 European countries and Israel. In the first quarter,  UPC announced it was
expanding  into new markets  through  the  purchase  of cable  companies  in the
Netherlands, France, and Slovakia.

WHICH STOCKS DID NOT LIVE UP TO YOUR EXPECTATIONS?

     Our  largest  holding,   German  financial  services  company  Marschollek,
Lautenschlaeger und Partner, had disappointing stock price performance.  Nothing
has changed fundamentally,  however. In fact, earnings have been strong and well
above expectations. Thus we are willing to wait out short-term underperformance.
Also,  we believe  there's still  potential  upside in both  Marschollek's  life
insurance and asset management segments.

     Netherlands-based   information  technology  consultant  Simac  Techniek--a
strong performer for many years--was hurt by unexpected  losses at the company's
German and British subsidiaries.

     Another disappointment was British-based pharmaceutical company Skyepharma,
which uses proprietary technology to develop controlled-release

versions  of existing  drugs for major  pharmaceutical  companies.  Skyepharma's
earnings  were hurt by the delay in its version of SmithKline  Beecham's  Paxil,
the  world's  second-best-selling  antidepressant.  Some  investors  have  grown
impatient,  but we still have  confidence in management  and are willing to wait
until the proposed  fourth quarter  launch  because the new drug's  potential is
great. Paxil's annual sales are more than $1 billion.

     Besides  disappointments  in individual  stocks, our European holdings as a
whole  were  hurt  by the 9%  decline  in  the  value  of  the  euro  since  its
introduction in January.

WHAT CHANGES DID YOU MAKE IN THE  PORTFOLIO DURING THE PERIOD?

     A major purchase was Kookmin Bank,  Korea's  largest  retail bank.  Kookmin
weathered the economic crisis well because of its conservative  mortgage lending
practices and is recovering  strongly with the economy.  Kookmin  acquired Korea
Long Term Credit Bank in 1988,  assuming  its  troubled  loan book,  but gaining
access to a very large  corporate  client  base.  We also  invested  in Sembcorp
Logistics, a company that has sold off a number of unprofitable  subsidiaries in
order  to  focus on its  expanding  outsourcing  business.  Earnings  growth  is
beginning  to expand  and the  company  is in  discussions  on a number of other
contracts.

     Another new holding is software  developer  Open Text.  The company's  main
product, Livelink, is a software application similar to LotusNotes, but Livelink
also gives users the ability to communicate across intranets, extranets, and the
Internet.  Livelink  software  has an  installed  base of  three  million  users
worldwide  at 3,600  companies.  Open Text is growing at a rapid  clip.  For its
third fiscal quarter ended March 31, 1999, license revenues were up 87% to $14.3
million.

WHAT IS YOUR OUTLOOK FOR INTERNATIONAL INVESTING GOING FORWARD?

     We continue to be positive on the global outlook,  especially with Asia now
entering a recovery  phase.  The world  markets are stable,  economic  growth is
healthy,  and inflation is benign. We feel this is a great environment to search
the globe for  smaller,  fast-growing  companies  that are well  positioned  for
tomorrow's  opportunities and challenges.  With companies in both Asia and Latin
America beginning to show signs of earnings growth, we expect to further broaden
the portfolio as we uncover new and exciting investment ideas.

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

[photo of Mark Kopinski and Michael Donnelly]

     An interview  with Mark  Kopinski  (left) and Michael  Donnelly,  portfolio
managers on the Emerging Markets team.

HOW DID EMERGING MARKETS PERFORM FOR THE SIX-MONTH PERIOD ENDED MAY 31, 1999?

     Emerging  Markets  posted a 24.07%*  return,  compared  to  23.79%  for its
benchmark, the Morgan Stanley Capital International Emerging Markets Free
Index.

WHICH COUNTRIES OR SECTORS HELPED YOU OUTPERFORM YOUR BENCHMARK?

     Asia has been one of the most  dynamic  regions of late and we were able to
find good  growth  stocks in both South  Korea and  Singapore.  South  Korea has
really been the star of Asia with  respect to the  resurgence  of its  corporate
sector. Since September 1998, we have been adding to and expanding the number of
our holdings in South Korea,  whose  government has put specific  initiatives in
place in order to guide  companies to  restructure  quickly and help rebuild the
economy.  Many  of the  South  Korean  companies  we have  researched  or met in
one-on-one  meetings have been keen on restructuring their business and reducing
their debt  burdens to more  effectively  compete  in  increasingly  competitive
domestic and global markets.

     In Latin America,  we found  surprisingly  strong  earnings  performance in
Mexico,  which has been the best  performing  Latin  American  economy so far in
1999.  Interest rates have declined and consumer  demand has increased,  despite
the turmoil in the rest of Latin America.  In addition,  strong demand for loans
helped the banking  sector,  and bankers reduced  provisions for  non-performing
loans, which directly feeds to the bottom line. Moreover, several sectors of the
Mexican economy, such as telecommunications and cement manufacturing,  have been
buoyed by rising prices.

     Mexico is an oil exporter, and they received a boost from higher oil prices
in 1999. That revenue flows directly into the country's  reserve base,  which in
turn  allows  the  government  to reduce  interest  rates  and halt the  extreme
downward  pressure on the overall  budget.  The robust U.S.  economy also helped
fuel growth in Mexico.  Spending on infrastructure  boosted cement companies and
other  construction-  related  industries.  We  purchased  Cemex SA, the world's
third-largest  cement producer.  The company's  first-quarter  sales rose 10% on
strong cement sales in both the United States and Mexico.

     We also  maintained  a lower  cash  position  than  the  fund's  historical
average. After a very rough 1998 --when many markets corrected 50% or more--1999
has given us a much larger menu of companies  with good earnings  growth.  As we
took advantage of these opportunities, we kept cash in the 2%-3% range, compared
to a 4%-6% historical average.

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

WHICH STOCKS OR SECTORS CONTRIBUTED MOST TO RETURNS?

     We discovered  growing  earnings in banks,  telecommunications,  electronic
component  manufacturers,  and computer  software  companies in many  developing
markets.

     Two of Emerging  Markets'  top-performing  stocks were Mexican  banks Grupo
Financiero Bancomer and Grupo Financiero Banorte,  both large and liquid stocks.
These banks began to lend again after lower  interest  rates spurred  demand for
commercial  loans.   Profit  margins  were  aided  by  reducing  provisions  for
non-performing  loans after government  legislation reduced the risk of bad debt
exposure  resulting from the 1995  devaluation of the peso.  More  specifically,
Grupo  Financiero  Banorte has  benefited  from having a high  concentration  of
clients who run businesses that export to the United States.

     Another top  contributor,  cellular  phone operator  Egyptian  Mobile Phone
Network,  experienced strong subscriber growth in the first quarter. That growth
should  continue for several years  because the demand for cellular  services is
huge in Egypt,  which has very low  teledensity  and is very populous.  Egyptian
Mobile began 1999 with 157,000 customers and grew that 44% to 226,000 by the end
of the first  quarter.  As in many other  emerging  markets  where  local  phone
companies are inefficient, cellular phones are in great demand because customers
must wait years to get a phone line hooked up to their homes.

     Just  as in U.S.  stock  markets,  the  Internet  has  also  ignited  stock
performance  in many overseas  markets.  Companies that benefited from the trend
included  Pacific  Internet  Ltd., a pan-Asia  Internet  service  provider,  and
Singapore-based  Datacraft Asia Ltd, which  designs,  builds,  and services data
communication   systems   throughout  Asia  and  other  regions.   Computer  and
peripherals  retailer GES International  also got a boost from the Internet when
it began selling hardware and parts via its Web site.

     Two  Indian  software  companies--Infosys   Technologies,  Ltd.  and  Wipro
Ltd.--continued their record of strong growth. Both companies benefit from their
client  relationships  in the  United  States  and  Europe and the lower cost of
operating in India.  Also, because they are located in different time zones than
their Western customers,  Wipro and Infosys operate during European and American
non-business hours,  thereby enabling them to offer many specialized value added
services and faster turnaround time.

WHY WERE THERE SO MANY BRAZILIAN STOCKS THAT HURT PERFORMANCE?

     The  short  answer  is  our   returns--calculated   in  U.S.  dollars--were
negatively  impacted  by the  devaluation  of the  Brazilian  real  in  January.
Consequently,  seven out of the portfolio's  eight worst performing  stocks were
Brazilian.  These included Celesc, Tele Sudeste Cellular,  Banespa,  Banco Itau,
Sabesp,  Electrobras,  and  Embratel.  Although  the  local  operations  of  the
companies,  for the most  part,  performed  as well as could  be  expected  in a
difficult  environment,  the  sharp  currency  devaluation  contributed  to weak
performance  when measured in U.S.  dollars.  We lowered our Brazilian  holdings
somewhat during the devaluation and were  underweight in the region.  Therefore,
the fund did not get a large boost when the  Brazilian  stock  market  rebounded
sharply after inflation failed to materialize.

     Our  position  in  Petroleo  Brasileiro,   Brazil's  largest  oil  refiner,
demonstrates what would have happened if we had

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

increased our Brazilian exposure in the month following devaluation. Rather than
sell Petroleo  Brasileiro during the devaluation,  we built the position further
and it is now one of our best performing stocks.

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

     We found  several good growth  opportunities  in South Korea.  For example,
auto parts supplier Halla Climate Controls received several large contracts from
Ford to supply auto parts.  These orders  coincided with a pick up in demand for
automobiles in Korea. Another contributor was Shinsegae Department Stores, which
operates  both a  discount  chain  and  mainline  department  stores.  After the
economic collapse in Asia, the discount chain was able to maintain sales because
consumers cut back on luxury items and moved their  purchases to discount shops.
Recently  there has been a revival in the  fortunes of its  mainline  department
stores as well. In addition, the company is reducing its debt burden.

     We also were able to find growing companies in Singapore and established or
built positions in several technology-related companies.

WHAT IS YOUR OUTLOOK FOR EMERGING MARKETS?

     Overall, we are optimistic because we do not currently see a major currency
collapse  or  economic  upheaval  on the  horizon.  During  most of  1998,  many
companies cut export prices  dramatically  in an effort to liquefy and stabilize
their balance sheets.  In effect,  inventory was being dumped on global markets,
severely  impacting the profitability of export sales. The dumping peaked during
the latter part of 1998, easing the pressure on the global economy.  Most of the
excesses  generated by  overvalued  currencies  are now gone,  commodity  prices
appear to have bottomed,  and producers are selling at  competitive  prices once
again.  South Korea was perhaps the first country to lead the way. Now, in stark
contrast to the situation in 1998,  economic  growth has returned to many of the
countries  that  suffered  currency  devaluations,  and GDP  estimates are being
revised up on a consistent basis.

     It's  important,  though,  to monitor the  progress of the reform  programs
implemented by the International  Monetary Fund (IMF). We believe that economies
that accept the  program--i.e.,  adopt  fundamental  changes in the way in which
fiscal budgets are balanced and  corporations  are  governed--should  be able to
foster  economic and financial  growth.  Those that only  implement  reform on a
piece-meal basis risk the likelihood of stagnation.

     We would also like to emphasize the breadth and quality of the companies we
are finding daily in the emerging  markets.  Exciting finds run the gamut from a
local   beverage   producer   (La   Tondenda)   to  the  maker  of   world-class
pharmaceuticals  (Pliva). We intend to continue to search for the best companies
to add to the portfolio in this robust environment.

Global Growth--Q&A
- --------------------------------------------------------------------------------

[photo of Bradley Amoils and Henrik Strabo]

     An  interview  with  Bradley  Amoils  (left) and Henrik  Strabo,  portfolio
managers on the Global Growth team.

GLOBAL  GROWTH  OPENED ON  DECEMBER 1, 1998.  SINCE THIS IS THE FIRST  REPORT TO
INVESTORS,  WILL YOU  TELL US ABOUT  GLOBAL  GROWTH'S  OBJECTIVES  AND HOW IT IS
MANAGED?

     Certainly,  but  first  we'd  like  to take  this  opportunity  to  welcome
investors to the fund.  We're excited about Global Growth's  potential,  and the
range of opportunities in which the fund is allowed to invest.

     Global   Growth's   charter  is  similar  to   American   Century's   other
foreign-stock  funds.  The funds share a common  objective of  long-term  growth
through  investments in companies  that  demonstrate  accelerating  earnings and
revenue  growth.  However,  unlike its  sibling  funds,  which have  significant
exposure  primarily in foreign  stocks,  Global  Growth has the  opportunity  to
invest in the United States. Because it has no geographical constraints,  Global
Growth can buy the fastest-growing companies, no matter where they are located.

     To find stocks for the portfolio,  we employ American Century's proprietary
database  of  more  than  15,000  foreign  and  domestic  companies.  We are not
restricted  by region,  market  sector,  or industry.  We also rely on extensive
research  provided by our team of  investment  analysts.  They  research  stocks
individually,  but each analyst has expertise in a particular  region.  Our team
travels  frequently,  looking for  opportunities  that fit our growth investment
style. We visit regularly with key executives, government officials, and central
bankers,  as  well  as  customers  and  competitors  of  the  companies  we  are
considering for investment.

HOW HAS GLOBAL GROWTH PERFORMED SINCE ITS INCEPTION?

     It has  performed  very well in the few  months  it has been in  operation.
Global  Growth's  life-of-fund  return as of May 31, 1999, was 18.60%*.  It more
than  doubled  the return of its  benchmark,  the MSCI World Free  Index,  which
gained 8.04% in the same time frame.

WHAT FACTORS INFLUENCED OVERALL  PERFORMANCE?

     Clearly,  the  decision  to focus  investments  in the  United  States  and
selectively  add  companies  in  Asia  was  an  important   factor.   Given  the
uncertainties  surrounding  global  capital  markets after the Asian crisis,  we
focused  our  investments  in the United  States,  which  offered  the  clearest
earnings visibility.  Large-capitalization  U.S. stocks that are benefiting from
increasing  efficiencies  through mergers and  restructurings  provided the most
attractive investment opportunities.  Furthermore, U.S. dominance and innovative
leadership in telecommunications, the Internet, media, pharmaceutical, financial
services, and biotechnology compelled us to concentrate our investments in these
arenas.  As a  result,  approximately  50% of the  fund  was  invested  in  U.S.
companies.

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

     In Europe,  the  portfolio  benefited  from a focus on  telecommunications,
outsourcing,  retailing,  and financial  services--industries  that demonstrated
strong underlying growth in their basic business. However, performance in Europe
was offset by the  depreciation of the euro (the new European common  currency),
slower than  expected  economic  growth,  and negative  money flows as investors
concentrated  on the United  States and Asia.  We  continued  to be  cautious in
Japan,  where we saw few  investment  opportunities.  Accordingly,  we purchased
companies that stood to benefit the most from a formalized restructuring plan or
that were  poised to take  advantage  of an  increasingly  deregulated  Japanese
economy.  As stability returned to the world's emerging markets, we put money to
work  selectively  in Hong  Kong,  South  Korea,  and  Singapore.  We also found
opportunities  in Brazil,  where  corporations  began to show signs of  earnings
re-acceleration.

WHICH SECTORS OR COMPANIES CONTRIBUTED THE MOST TO RETURNS?

     As  we   mentioned   earlier,   investors   maintained--and   perhaps  even
intensified--their  preference  for a handful of U.S.  companies for much of the
period.  These  companies  also  represented  a  significant  portion  of Global
Growth's portfolio.

     Several industry groups,  particularly in the technology sector,  that were
good  performers in the United States also fared well abroad.  Continued  robust
growth  in the  Internet  was the  catalyst  driving  earnings  for  many of our
technology  companies.  Internet-related  technology holdings that posted strong
gains  included Cisco Systems,  a maker of Internet  routers and equipment,  and
software giant Microsoft.

     Telecommunications  companies,  Global Growth's largest industry weighting,
were also among the portfolio's strongest  contributors.  These companies formed
three groups within the  telecommunications  area:  carriers of electronic voice
and  data,  cellular  service  and  equipment  providers,  and  cable TV  firms.
Companies  exhibiting  strong growth in one or more of these areas included AT&T
and MCI WorldCom in the United  States,  UPC and  Mannesman in Europe,  Nokia in
Finland, and Japan's NTT Data.

DID YOU FIND GROWTH IN MANY SECTORS  OUTSIDE THE TECHNOLOGY ARENA?

     Global Growth's  financial  services  holdings were helpful.  Firms such as
Standard  Chartered  and  the  American   International  Group  (AIG)  performed
exceptionally  well after the U.S. Federal Reserve began to cut interest rate in
what proved to be a successful effort to stabilize world markets. Strong revenue
growth from insurance  annuity sales in the United States  continued to buoy the
earnings of Sweden's Skandia Holdings.

WHICH SECTORS OR HOLDINGS WERE  DISAPPOINTING?

     The portfolio's  worst-performing holding was American tobacco giant Philip
Morris.  Ongoing lawsuits against tobacco manufacturers and recent adverse court
rulings have increased  investors' concerns about the future of big tobacco, and
that drove tobacco stocks down across the board. Philip Morris was no exception.
We eliminated the position.

     The German retailer, Douglas Holding, also disappointed. Douglas markets a
broad range of high-end retail products, including perfume, jewelry, personal
care products, and books. The

healthy  economies in Europe and the United States helped drive growth in recent
years. However,  sales in Germany, the company's primary market, began to lag in
April when warmer  weather  pulled people away from shopping and toward  outdoor
activities.  This shift impacted  earnings and ultimately share price, but we're
confident these problems are temporary and are holding Douglas.

WHAT'S YOUR OUTLOOK FOR GLOBAL INVESTING?

     We continue to find tremendous  opportunities  for investing in interesting
and  fast-growing  companies in almost every corner of the world. We now live in
exciting times as information,  capital,  goods, and services move freely around
the   globe   with   unprecedented   ease.   The   rapid   acceptance   of   new
technologies--witness  the  thousands  of new  Internet  users each day--is only
accelerating  this incredible trend. The world has truly become a global village
and we want to own those  companies  that are  positioned  to take  advantage of
major growth opportunities.

     After the worldwide economic upheaval last year, the global economy appears
to be on the mend.  With this as a backdrop,  we feel the outlook for  corporate

Statements of Assets and Liabilities
- --------------------------------------------------------------------------------

Also known as a balance  sheet,  this  statement  breaks down the fund's  ASSETS
(such as securities,  cash, and other  receivables) and LIABILITIES  (money owed
for  management  fees and other  expenses)  as of the last day of the  reporting
period.  Subtracting the  liabilities  from the assets results in the fund's NET
ASSETS.  For each class of shares, the net assets divided by the total number of
shares outstanding is the share price, or NET ASSET VALUE PER SHARE.

This statement also breaks down the fund's net assets into capital  (shareholder
investments) and performance (investment income and gains/losses).

Notes to Financial Statements
- --------------------------------------------------------------------------------

MAY 31, 1999 (UNAUDITED)

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  company.   International  Growth  Fund  (International
Growth),  International  Discovery  Fund  (International  Discovery),   Emerging
Markets  Fund  (Emerging  Markets) and Global  Growth Fund (Global  Growth) (the
funds) are the funds currently issued by the corporation.  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.  Global Growth
seeks to achieve its  investment  objective  by  investing  in U.S.  and foreign
equity securities of issuers in developed 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  Institutional  Class  and  Advisor  Class for
Emerging Markets  commenced on January 28, 1999 and May 12, 1999,  respectively.
Global  Growth's  inception  date and  commencement  of the  Investor  Class was
December  1, 1998.  Sale of the Advisor  Class for Global  Growth  commenced  on
February  5, 1999.  Sale of the  Institutional  Class for Global  Growth had not
commenced as of May 31, 1999. The following significant  accounting policies are
in accordance with generally accepted  accounting  principles;  these principles
may require the use of estimates by fund management.

    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.  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  -- All  assets  and  liabilities  initially
expressed in foreign  currencies are translated into U.S.  dollars at prevailing
exchange  rates at period end.  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.  Realized
and unrealized  gains and losses from foreign currency  translations  arise from
changes in currency 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 to  facilitate  transactions  of
securities  denominated in a foreign currency or to hedge the fund's exposure to
foreign  currency  exchange  rate  fluctuations.  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. 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  manager,  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
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  funds'  policy  to  distribute  all  net
investment  income  and net  realized  gains to  shareholders  and to  otherwise
qualify as a regulated  investment  company under the provisions of the Internal
Revenue  Code.  Accordingly,  no  provision  has been made for  federal or state
income taxes.

    DISTRIBUTIONS  TO SHAREHOLDERS -- Distributions 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  realized  gains  and  losses  for  financial
statement  and tax purposes  and may result in  reclassification  among  certain
capital accounts.

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

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

2. TRANSACTIONS WITH RELATED PARTIES

    The  corporation  has entered  into a  Management  Agreement  with ACIM that
provides each fund with investment  advisory and management services in exchange
for a single,  unified management fee per class. The Agreement provides that all
expenses of the funds, except brokerage commissions,  taxes, interest,  fees and
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

       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 May 31,
1999,  were $69,088,  $34, $6 and $36 for  International  Growth,  International

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.

    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.

    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 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 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 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.

INVESTMENT PHILOSOPHY AND POLICIES

    American   Century  offers  13  growth  funds  including   domestic  equity,
specialty,  international,  and global. The philosophy behind these growth funds
focuses on three important  principles.  First, the funds seek to own successful
companies,  which we define as those with growing earnings and revenues. 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." 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.   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.

    GLOBAL  GROWTH  invests  primarily  in equity  securities  of both U.S.  and
foreign  companies.  These  companies  will be  primarily  located in  developed
countries.

    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

COMPARATIVE INDICES

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

    The S&P 500 is a capitalization-weighted index of the stocks of 500 publicly
traded  U.S.  companies  that are  considered  to be leading  firms in  dominant
industries.  Created by Standard & Poor's Corporation,  it is considered to be a
broad measure of U.S. stock market performance.

    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  MSCI  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.  Within this index is a narrower  index,  MSCI  EMERGING
LATIN AMERICA,  which measures the performance of stocks in seven Latin American
countries.

    The MSCI WORLD FREE INDEX is an index of approximately 1600 companies listed
on stock  exchanges in 22 developed  market  countries--in  order of their index
weightings  as  of  3-31-99:  USA,  Japan,  United  Kingdom,   Germany,  France,
Switzerland,  Netherlands,  Italy, Canada, Spain, Australia,  Sweden, Hong Kong,
Finland, Belgium,  Singapore,  Denmark, Portugal,  Ireland, Austria, Norway, New

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 48-58.

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.

FUND CLASSIFICATIONS

INVESTMENT OBJECTIVE

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

* CAPITAL  PRESERVATION  -- offers  taxable and tax-free  money market funds for
relative stability of principal and liquidity.

* INCOME -- offers funds that can provide current income and competitive yields,
as well as a strong and stable  foundation and generally lower volatility levels
than stock funds.

* GROWTH & INCOME --  offers  funds  that  emphasize  both  growth  and  income,
provided  by either  dividend-paying  equities  or a  combination  of equity and
fixed-income securities.

* GROWTH -- offers  funds with a focus on  capital  appreciation  and  long-term
growth,  generally providing high return potential with corresponding high price
fluctuation risk.

RISK

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

*  CONSERVATIVE  -- these funds  generally  provide lower return  potential with
either low or minimal price fluctuation risk.

* MODERATE -- these funds  generally  provide  moderate  return  potential  with
moderate price fluctuation risk.

*  AGGRESSIVE  -- these  funds  generally  provide  high return  potential  with
corresponding high price fluctuation risk.

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