     The six months ended May 31, 2000, rewarded investors in American Century's
global and international equity funds with double-digit returns. All four funds
outperformed their benchmarks.

     A major shift in investor sentiment occurred during the period. At the
start, growth stocks -- especially those of Internet- and telecommunications-
related technology companies -- led the U.S. and most international markets
higher. Later, though, concerns about inflation, rising interest rates, and rich
technology-stock valuations sparked a sudden and powerful move into other stock
sectors. The tech-heavy Nasdaq Composite Index lost more than 25% in one week in
early April, which rippled through most international equity markets, causing
our funds to give back some of their gains.

     We're also proud to announce that American Century's fund performance
reports, like this one, earned the Communications Seal from DALBAR, Inc., an
independent financial services research firm. They commended us for meeting
investors' needs with an attractive document that's easy to read and understand.
DALBAR also ranked the American Century Web site fifth among the 25 mutual fund
company sites it rated, based on functionality, ease of use, and editorial
content.

     We're also pleased to provide investors with two new investment tools. Fund
Advisor,(1) an online advice engine, is designed to give impartial guidance in
choosing the right no-load mutual funds to meet your financial goals.(2) And
American Century is the program manager for Learning Quest(reg.sm), an
educational savings program launched by the state of Kansas on July 1 that
allows parents to invest tax-deferred to meet higher education costs. The summer
issue of the American Century investor newsletter provides more details on these
tools.

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

Sincerely,

/signature/                           /signature/

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

MARKET PERSPECTIVE

* The six-month period ended May 31, 2000, was marked by a powerful shift in
  investor sentiment. As the period opened, growth stocks, especially those of
  technology-oriented companies, continued to lead many international markets.
  Toward the end of the period, though, higher U.S. interest rates and
  uneasiness about rich valuations across the technology sector led investors to
  move en masse into other areas. As a result, many international markets moved
  lower.

INTERNATIONAL GROWTH

* International Growth gained 10.80% during the six months ended May 31, 2000,
  significantly outperforming its benchmark, the Morgan Stanley Capital
  International EAFE Index, which rose just 0.61%.

* Wireless telecommunications and electrical equipment companies were among
  International Growth's strongest performers. Companies in both groups
  benefited from explosive, worldwide growth in wireless communications and the
  demand for greater bandwidth capacity on the Internet.

INTERNATIONAL DISCOVERY

* International Discovery was up 14.82% for the six months, far surpassing its
  benchmark, the Morgan Stanley Capital International EAFE Index, which gained
  0.61%.

* Internet service providers, computer hardware makers, and electrical equipment
  companies were among the top contributors to performance. Positions in health
  care and biotech companies also provided a boost, as did financial services
  companies driven by the new American-style capitalism and equity culture in
  many international markets.

EMERGING MARKETS

* Emerging Markets gained 11.39% during the period, outperforming its benchmark,
  the Morgan Stanley Capital International Emerging Markets Free Index, which
  increased just 0.18%.

* Emerging Markets capitalized on the strength of semiconductor companies, which
  were among its top performers for the period. This group was buoyed by the
  favorable outlook for this area, which is expected to remain steady, even in
  the face of a possible economic slowdown.

* Developments in Russia overshadowed many other emerging markets during the
  period. Sentiment about the Russian economy and political system suddenly
  turned positive, and favorable economic conditions there gave rise to
  attractive opportunities for the fund.

GLOBAL GROWTH

* Global Growth posted a solid gain of 15.16% during the period, outpacing its
  benchmark, the Morgan Stanley Capital International World Free Index, which
  rose 1.90%.

* A diverse group of stocks contributed to performance, including companies
  involved in high-speed fiber-optic communications, television, and
  telecommunications. Domestic contributors included energy companies and
  computer hardware firms.

* Holdings of financial services companies, the fund's second-largest sector
  position, also boosted returns, as European demand for such services increased
  amidst sweeping pension reform.

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

[photo of Henrik Strabo]

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

PERFORMANCE OVERVIEW

     Our international and global funds performed well during the six months
ended May 31, 2000. Extreme volatility characterized the markets, so managing
the funds presented some additional challenges. During the first half of the
period, stocks benefited from an optimistic outlook, particularly for the
technology and telecommunications sectors, which carried most indices to new
highs. Around the middle of March, a general discomfort about the strength of
economic activity gave rise to concerns about higher interest rates. The U.S.
Federal Reserve and other central banks around the world actually tightened
monetary policy, which resulted in fears of a global economic slowdown.

     Each one of our four equity funds was able to navigate the changing tides
of the foreign markets and posted total returns well ahead of their respective
benchmark indices, as measured by Morgan Stanley Capital International. In
addition, all the funds performed well relative to their peer group averages.

     Although periods of volatility in the markets are disconcerting, we manage
our portfolios with the objective of producing strong performance over the long
haul. We focus our efforts on researching and investing in companies that can
formulate and execute solid business plans that either keep them in, or propel
them to, leadership positions in their industries. At the same time, we are
keenly interested in seeing that candidates for the portfolios display superior
earnings growth. Finally, we search for evidence that these companies embrace
the technological developments that allow them to stay ahead of the pack.

THE GLOBAL FREEDOM MACHINE

     One such development is what we call the Global Freedom Machine. The
convergence of wireless telecommunication and the Internet has created a class
of companies that is revolutionizing the way we interact. We are moving away
from the personal computer and entering the era of mobile computing and
communication. This is enabling millions of people in Japan and Europe to shop,
trade securities, bank and buy airline tickets using just their mobile phones.
As you review this report, you will see this theme represented in each fund's
portfolios.

     In conclusion, we would like to assure you that the team working on these
funds is entirely focused on continuing to provide solid investment performance.

The graph at left shows the growth of a $10,000 investment over the life of the
fund, while the graph below shows the fund's year-by-year performance. The MSCI
EAFE Index is provided for comparison in each graph. Index performance is based
on returns since 4/30/91, the date nearest the class's inception for which data
are available. International Growth's total returns include operating expenses
(such as transaction costs and management fees) that reduce returns, while the
total returns of the MSCI EAFE Index do not. The graphs are based on Investor
Class shares only; performance for other classes will vary due to differences in
fee structures (see the Total Returns table above). Past performance does not
guarantee future results. Investment return and principal value will fluctuate,
and redemption value may be more or less than original cost.

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

[photo of Mark Kopinski and Henrik Strabo]

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

HOW DID INTERNATIONAL GROWTH PERFORM FOR THE SIX MONTHS ENDED MAY 31, 2000?

     International Growth gained 10.80% for the period, well ahead of the 0.61%
increase posted by its benchmark, the Morgan Stanley Capital International EAFE
Index.* The fund easily outdistanced its peers, as well. The 684 international
funds tracked by Lipper Inc. delivered an average return of 2.25%.

     For the year ended May 31, 2000, International Growth gained 48.27%, versus
17.14% for the EAFE Index, and the 25.62% average for 649 international funds
tracked by Lipper. The fund has especially rewarded long-term shareholders,
providing an average annual return of 22.09% over the past five years, versus a
12.16% average for 266 peers tracked, and 10.08% for its benchmark.

BEFORE DISCUSSING YOUR INVESTMENTS, COULD YOU OUTLINE THE STRATEGY THAT ENABLED
YOU TO OUTPERFORM YOUR BENCHMARK AND PEERS?

     Our investment philosophy centers on owning successful, fast-growing
businesses. In fact, the most attractive company to us is one whose revenues and
earnings are growing at an accelerating rate. Equally important, we want solid
evidence that a company is able to sustain its growth, and we do extensive
fundamental research and analysis to convince ourselves on this point. In 1999,
American Century's international investment team visited more than 1,400
companies, meeting face-to-face with top management. That's possible when you
have a determined staff of investment professionals who speaks a total of 13
languages.

TURNING TO YOUR PORTFOLIO, WHAT WERE SOME OF INTERNATIONAL GROWTH'S MOST
SUCCESSFUL INVESTMENTS DURING THE PERIOD?

     One top-performing stock (up 128%) was Sweden's Skandia Forsakrings AB, the
Nordic region's largest insurer and a major U.S. distributor of variable
annuities--investment contracts that pay income during retirement. Skandia
distributes its packaged financial services, including Web sites and financial
planning software, primarily through investment advisors. The company doubled
its first-quarter profits from a year earlier.

     Alcatel Alsthom Compagnie Generale (up 54%), a French telecommunications
equipment company that progressed into our top-10 holdings, has been a
successful investment for us. Alcatel recently acquired Newbridge Networks, a
Canadian manufacturer of network communications systems and products that has
been steadily adding to its franchise of switched telecommunications equipment
over the past two years.

     After recovering from difficulties in 1998, Alcatel has been transforming
itself into a leading provider of packet-based Internet and wireless equipment.
The company has a dominant market share in central office equipment, as

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

well as in the market for the modem used in digital subscriber line (DSL)
services that are rapidly being introduced to provide high-speed Internet access
to homes in the United States and Europe.

     We also were pleased with our investment in an Israeli-based company, Check
Point Software Technologies Ltd., (up 165%). This firm provides "firewall"
software that guards computer networks against intrusion. Its shares got a boost
after the "I Love You" virus crippled e-mail systems worldwide and highlighted
the need for computer network security.

WHAT IS BEHIND YOUR SIGNIFICANT INVESTMENTS IN COMPANIES INVOLVED WITH VARIOUS
ASPECTS OF WIRELESS COMMUNICATIONS?

     We're very excited about the investment opportunities arising from the
marriage of wireless communications and the Internet. Our travel abroad has
shown us that the global community is rushing toward what some have called
"ubiquitous communication," made possible by a mobile Internet.

     Most Americans access the Internet with a desktop PC, but in Europe and
Japan, the mobile phone is increasingly the medium of choice. In our eyes,
mobile telephony is the ultimate "Global Freedom Machine," enabling people to
communicate whenever they want to and wherever they may be, not just when they
are sitting at their computers.

     The mobile information society is an everyday reality in other countries.
Take Finland, for example. This country of five million people has three million
cell phones, and Finns do more than just talk on them. They send lots of e-mail
messages--500 million of them last year.

     We have invested in several companies at the forefront of this cordless,
Internet-linked communications revolution, beginning with Finland's Nokia Corp.
Cl A, virtually the founder of mobile communications and the world's leading
producer of cellular phones. Nokia is feverishly working to double the
production capacity of its main plant in Texas. The step-up is necessary as the
number of wireless subscribers worldwide, estimated at 500 million, has been
doubling every 20 months!

     Another top-10 holding, Ericsson (L.M.) Telephone Co. ADR, is an important
wireless investment. Ericsson is among the companies developing "third
generation" wireless technology that will enable networks to carry broadband
communications such as videoconferencing and multimedia. This technology has the
potential to change the entire concept of a telephone number. Soon, numbers will
be associated with people, not locations. One will be able to make and receive
calls anywhere in the world with the same cellular handset and the same number.

ALMOST 20% OF THE FUND IS INVESTED  IN COMPANIES INVOLVED IN ELECTRICAL
EQUIPMENT. WHERE DID YOU FIND GROWTH  IN THAT GROUP?

     A number of our investments in this area make electrical components used in
communications networks or personal computers. Two of note are Canada's Nortel
Networks Corp., and Korea-based Samsung Electronics. Nortel is a leading maker
of equipment for high-speed data networks. Samsung Electronics is one of the
world's largest producer of DRAM (memory) chips for personal computers. It is
also a leader in technology for liquid crystal displays (LCDs) used in notebook
computers and hand-held devices.

WHAT ARE SOME OTHER COMPANIES THAT CONTRIBUTED TO YOUR RESULTS?

     We added to our investment in one of Germany's best-known industrial
companies, Siemens AG. This conglomerate provides products ranging from
locomotives and automotive electronics to medical equipment and household
appliances. Siemens is shaping a new industrial environment by bringing
information technology into the factory, whether in the form of Internet links
between customers and suppliers, or software aimed at improving or streamlining
industrial processes.

     We are also taken with the Swiss multinational, ABB Ltd., one of the
world's biggest electrical engineering companies. ABB is applying information
technology to pursuits such as power transmission, factory automation, and
energy exploration. Its earnings grew 24% in 1999.

WHAT HOLDINGS DID NOT LIVE UP TO  YOUR EXPECTATIONS?

     One was NTT Data Corp., the data systems development arm of Japan's Nippon
Telegraph & Telephone Corp. NTT Data does computer networking and systems
integration for big companies and government entities. We sold the stock, a
reasonably large position at 1.6% of assets, when orders for the company's
services appeared to be slowing. We also learned that the company was intent on
becoming an Internet service provider. This represented a late move into an
extremely competitive area -- a move we felt might threaten earnings.

     Hennes & Mauritz AB, the leading clothing retailer in Europe, lost value
during the first quarter as a result of slowing sales on the Continent and
expansion costs when the company recently opened its first store in New York.

WHAT'S YOUR OUTLOOK FOR THE NEXT  SIX MONTHS?

     Rising interest rates in the United States and overseas are setting a tone
of volatility and uncertainty in many international markets. Our jobs become
more challenging in times like these. Again and again, we put each company we
own under a microscope to ensure that the fundamentals that led us to buy the
stock are still in place and that the company is in position to sustain its
growth. Our disciplined approach, coupled with our extensive research and
analysis, is designed to lead us to individual companies around the world that
can grow into the foreseeable future. We try to own the best possible set of
companies, regardless of the economic climate.

The graph at left shows the growth of a $10,000 investment over the life of the
fund, while the graph below shows the fund's year-by-year performance. The MSCI
EAFE Index is provided for comparison in each graph. International Discovery's
total returns include operating expenses (such as transaction costs and
management fees) that reduce returns, while the total returns of the MSCI EAFE
Index do not. The graphs are based on Investor Class shares only; performance
for other classes will vary due to differences in fee structures (see the Total
Returns table above). Past performance does not guarantee future results.
Investment return and principal value will fluctuate, and redemption value may
be more or less than original cost.

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

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

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

HOW DID INTERNATIONAL DISCOVERY PERFORM FOR THE SIX MONTHS ENDED MAY 31, 2000?

     International Discovery performed well for the period, gaining 14.82%.* Its
return significantly outdistanced its benchmark, the Morgan Stanley Capital
International EAFE Index, which was up just 0.61%. The fund also outperformed
most of its peers. The 75 international small-cap funds tracked by Lipper during
this period had an average return of 7.92%.

     Longer-term, the fund gained a remarkable 63.12% for the year ended May 31,
2000, versus 17.14% for the EAFE, and a 52% average return for its 72 peers
tracked during this period. For the five years ended on the same date,
International Discovery posted an average annual return of 29.58%, versus an
average of 18.21% for its 15 Lipper peers, and 10.08% for its benchmark.

growth. The words "around the world" are important: our success is based on
building the portfolio one company at a time with the best businesses we can
find, no matter where they may be. Just as importantly, our staff conducts
extensive investigation and analysis to make sure these businesses are capable
of sustaining the growth that led us to them in the first place. In fact, in
1999, our staff, who speaks a total of 13 languages, visited more than 1,400
companies, meeting face-to-face with top management.

TURNING TO YOUR PORTFOLIO, WHAT WERE  SOME OF INTERNATIONAL DISCOVERY'S MOST
SUCCESSFUL INVESTMENTS?

     Our top contributor was Tiscali S.p.A. (up 234%). The firm, which is
Italy's first free Internet service provider, has 2.1 million subscribers, up
31% from just three months ago. Even after the general technology decline
throughout March, April, and May, Tiscali's shares are up 12-fold since they
started trading last October.

     Switzerland's Logitech International S.A. (up 150%), is the world's top
computer "mouse" maker, and was also a strong contributor. This company has
pioneered the cordless keyboard and PC video cameras. Logitech has experienced
six consecutive quarters of  record revenues.

     Another successful investment (up 150%) was Vestas Wind Systems A/S, a
Danish producer of wind turbines. There is a push across Europe to move to
"green electricity" (generated through renewable energy sources such as wind and
wave power), and Vestas is a major producer in a market that expanded almost 40%
in 1999.

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

TECHNOLOGY-ORIENTED COMPANIES ACCOUNT FOR MORE THAN 30% OF THE FUND. WHAT'S YOUR
PERSPECTIVE ON THESE INVESTMENTS  IN LIGHT OF THE STEEP CORRECTION  THEY
UNDERWENT?

     Foreign markets, especially in Europe, reacted to the technology stock
meltdown in the United States, and tech stocks were pretty much hurt across the
board. Investors particularly appeared to lose patience with unseasoned or
untested high-tech companies, those with no earnings. Our approach is designed
to lead us to technology businesses that are successful today, with strong
fundamentals. Not only do we think they provide the best opportunities for
long-term results, but it has been our experience that successful, growing
businesses--in and out of technology--often snap back the fastest after a broad
market decline.

WHAT ARE SOME INVESTMENTS THAT  ILLUSTRATE THIS PHILOSOPHY?

     Take Singulus Technologies (up 86%), a position we initiated during the
period. This German company provides equipment for makers of digital videodiscs,
or DVDs. It is a key supplier of technology that seems destined to be the next
step in electronic equipment used for personal entertainment. Along those lines,
we also own shares of Kudelski SA, a Swiss electrical equipment company that
provides conditional access software for set-top cable boxes that will allow
people to buy things they see on TV with the swipe of a card.

     Demand for laptop computers and liquid crystal display (LCD) monitors is
growing rapidly in the workplace, and makers of these products are increasing
their production capacity. That's why we've invested in Orbotech Ltd., an
Israeli company making equipment to detect flaws in high-end LCD screens during
the production process.

     None of the technology firms in our portfolio are immune to sudden changes
in investor sentiment--no stock is. The key, though, is that the companies we
own are involved in technological advances that seem logical and inevitable. We
believe that helps position them to rebound strongly from downturns that are a
normal part of the investment process.

WHAT ARE OTHER INVESTMENT THEMES THAT PROPELLED THE FUND DURING THE PERIOD?

     We have a portion of International Discovery devoted to financial services
companies. The most noteworthy is our largest investment, the German financial
services company, Marschollek, Lautenschlaeger und Partner AG (MLP). We've owned
stock in this company, which is Germany's largest independent insurance broker,
since 1994, and it continues to be a bright spot in the portfolio. MLP rewarded
us over the six months with a 76% increase.

     Entrium Direct Bankers AG, a new holding in International Discovery, is
benefiting from the growing popularity of the Internet in Germany, Europe's
largest economy. Entrium is a pioneering, independent telebank offering online
banking services, brokerage loans, mutual funds, and credit cards. It conducts
business by telephone, by mail, and increasingly over the Internet to customers
in Germany and Austria. Its shares have doubled since an initial public offering
last September on Germany's Neuer Market.

     These and similar financial services holdings are benefiting from the
American-like "equity culture" that is sweeping across Europe. Ordinary citizens
are investing increasingly in capital markets across the Continent.

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

Until recently, one invested through a bank in Europe, or one did not invest.
Now, faced with funding their own retirements in the wake of widespread
government pension reform, millions of Europeans are turning to true financial
services providers.

WHAT ARE SOME OTHER COMPANIES THAT CONTRIBUTED TO YOUR RESULTS?

     Not every change in the workplace is technological. In Germany, new
government policies allow companies to hire people without having to give them
permanent jobs. That shift has created a demand for temporary, highly skilled
workers such as financial experts and engineers. Many are being provided by a
company whose shares we own called DIS Deutscher Industrie Service AG. These
kinds of workers command a high price, which companies are willing to pay in the
short term because they are saving money in the long run.

     Our positions in health care companies gave the fund a boost near the end
of the period. In the United Kingdom, Shire Pharmaceuticals Group PLC has
developed a drug called Reminyl that slows the progress of Alzheimer's disease.
It has received approval for distribution in Sweden and soon expects similar
approval in the rest of Europe. We also own stock in QLT Inc. This Canadian
biotech company, along with its U.S. partner, CIBA Vision Corp., began sales in
the United States of its eye-treatment product, Visudyne. This light-activated
treatment is used to treat macular degeneration, a disease that robs people of
their sight. The product is injected intravenously, then activated by shining
light into the eye.

WHICH STOCKS PERFORMED BELOW YOUR EXPECTATIONS?

     Eidos plc, the United Kingdom-based maker of video games such as "Tomb
Raider," announced in March that the sale of new titles had slowed and that it
was delaying the issue of new games. Eidos is Europe's largest maker of video
games, but its share price is down dramatically in 2000. We sold the position in
late January following indications that Eidos' growth would not meet our
expectations.

     We were also disappointed by Icon Medialab International AB, the Swedish
Internet consultant. The company suffered losses--the size of which surprised
the market--as it quickly expanded abroad to attract big clients. Icon helps
clients such as the Coca-Cola Co., set up and manage Web sites.

WHAT ARE YOUR PLANS FOR INTERNATIONAL DISCOVERY FOR THE REMAINDER OF 2000?

     We will continue practicing the same investment philosophy we have in the
past. That includes taking into account the kinds of changes that swept across
international markets last spring, while not being carried away by them.
International Discovery targets companies with solid fundamentals and strong
earnings, but even those weren't immune to the insecurity that gripped markets
in March, April, and May. We have been through periods like this before. In our
view, the best way to negotiate times of market volatility and uncertainty is by
owning the types of firms our strategy is designed to lead us to: successful,
growing companies with solid management. We believe this practice will continue
to reward all of us as shareholders.

The graph at left shows the growth of a $10,000 investment over the life of the
fund, while the graph below shows the fund's year-by-year performance. The MSCI
Emerging Markets Free Index is provided for comparison in each graph. Emerging
Market's total returns include operating expenses (such as transaction costs and
management fees) that reduce returns, while the total returns of the MSCI
Emerging Markets Free Index do not. The graphs are based on Investor Class
shares only; performance for other classes will vary due to differences in fee
structures (see the Total Returns table above). Past performance does not
guarantee future results. Investment return and principal value will fluctuate,
and redemption value may be more or less than original cost.

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

[photo of Mark Kopinski and Michael Donnelly]

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

HOW DID EMERGING MARKETS PERFORM DURING THE SIX MONTHS ENDED MAY 31, 2000?

     The fund performed well during this volatile period, particularly from a
comparative standpoint. Emerging Markets gained 11.39%, which far outdistanced
the 0.18% return of its benchmark, the Morgan Stanley Capital International
Emerging Markets Free Index.*

     The fund also significantly outperformed most other emerging markets funds.
The 195 emerging markets funds tracked by Lipper during the period posted an
average return of just 2.93%.

     Emerging Markets looked just as impressive from a longer-term perspective.
For the year ended May 31, 2000, the fund returned 44.57%. This compared
favorably with the 17.75% return for the index and a 23.51% average gain for 185
emerging markets funds tracked by Lipper. Based on these figures, Emerging
Markets ranked thirteenth out of the 185 funds** for the one-year period.

WHY DID EMERGING MARKETS PERFORM SO WELL COMPARED WITH ITS INDEX AND OTHER
FUNDS?

     We successfully executed our investment strategy. Our process led us to
some outstanding technology companies that elevated fund performance through the
beginning of March. The constant search for growing companies capable of
attracting additional investor interest provided a competitive advantage.

     Even though emerging market technology stocks suffered a correction in the
latter half of the six-month period (which corresponded to the decline of the
Nasdaq Composite Index in the United States), the overall contribution of our
technology investments we found was positive. And it is worth noting that those
stocks were starting to rebound as the period ended.

WHAT CHANGES DID YOU MAKE WHEN  TECHNOLOGY STOCKS BEGAN TO CORRECT  IN MARCH?

     We did not make any major changes. In fact, it is crucial to emphasize that
our commitment to our approach is just as important as the approach itself. We
stayed with most of our companies because we remained convinced that they were
sound investments. However, we pared back some of our positions and verified
that we still had compelling reasons for sticking with each holding.

     Our commitment to technology companies may cause short-term pain, but
markets do recover. The portfolio declined sharply in April, but it started to
bounce back at the end of May.

CAN YOU PROVIDE US WITH A REFRESHER ON YOUR INVESTMENT STRATEGY?

     We scour the globe for companies whose earnings are growing at strong and
sustainable rates. This company focus makes us bottom-up investors, rather than
top-down -- we do not rely solely on economic models to tell us what countries
or sectors in which to

invest. Instead, we analyze individual companies, particularly their earnings,
management, and business plans. As a group, we talked with more than 1,400
companies over the last 12 months, in most cases with the chief executive or
chief financial officers. We want to own the stocks of successful, growing
companies that are leaders in their fields.

WHAT WERE SOME OF THE KEY DEVELOPMENTS IN EMERGING MARKETS OVER THE LAST SIX
MONTHS?

     An important development that may have been missed by U.S. investors
happened in Russia, where sentiment about the political system and the economy
suddenly turned positive. Two events were primarily responsible. First, the
Russian people elected a Duma (Congress) that is committed to free market
policies and economic reform. Second, a new Russian president, Vladimir Putin,
was elected in March.

     While many news reports focused on the fact that Putin is a former KGB
agent, our perception is that he is intelligent, pragmatic, and an economic
reformer. The Russian people appear to be drawn to and energized by their new
president.

     Favorable economic conditions have also helped. Increased sales of Russia's
energy reserves -- particularly natural gas -- combined with higher energy
prices, have allowed Russia to rebuild its government coffers and reduce foreign
debt. As a result, Russian banks are more liquid, the economy is experiencing
robust growth, the currency has stabilized, and foreign investment is returning.

     These factors raised our confidence in several growing Russian companies.
We have added to the fund's Russian exposure by purchasing companies whose
earnings are growing substantially in this environment. Two energy companies,
Lukoil Holding and Surgutneftegaz Oil, are good examples of the types of Russian
investments we are making.

DIDN'T CHANGES IN THE U.S. CAPITAL  MARKETS ALSO HAVE A STRONG IMPACT  ON
EMERGING MARKETS?

     That is true. The Federal Reserve raised short-term interest rates by a
full percentage point during the six months, which rippled around the world and
helped trigger other rate increases. The resulting sharp decline in the Nasdaq
Composite Index also echoed globally. The declining confidence in the strength
of the U.S. economy has far-reaching implications in the emerging markets.

     However, growth opportunities still abound -- particularly in technology
and telecommunications -- and many companies are still expanding and increasing
their earnings.

SIMILAR TO RUSSIA, TAIWAN IS ANOTHER  PLACE WHERE YOU INCREASED YOUR HOLDINGS
SIGNIFICANTLY. IN FACT, IT BECAME YOUR  SECOND-LARGEST COUNTRY HOLDING, BEHIND
BRAZIL. WHAT WAS THE STORY THERE?

     This is a good example of where changes in country exposure do not tell the
whole tale. The real story here is semiconductors.

     Stocks of semiconductor companies were among the top performers during the
period. We believe the outlook for this group remains favorable, even if the
economy slows. We anticipate continued high demand for chips, particularly in
the expanding telecommunications sector where the barriers to market entry are
high for potential competitors.

     It happens that three leading global semiconductor companies are located in
Taiwan: United Microelectronics Corporation, Taiwan Semiconductor Manufacturing
Company Ltd., and Windbond Electronics Corporation, which together represented
5.5% of the fund as of May 31.

     The fund's top holding on this date, Korea's Samsung Electronics, is also
involved in semiconductor manufacturing, as well as many other businesses,
including consumer electronics, mobile phones, monitors, televisions, and home
appliances.

SHIFTING GEARS, WAS THERE A SITUATION WHERE YOUR PROCESS WAS NOT AS EFFECTIVE?

     Let's talk about South Africa, a case where the country exposure told a big
part of the story. One of the potential risks of global investing is currency
depreciation. South Africa was an example where a weakening currency affected
fund returns. It did not matter how strong South African company earnings growth
or stock prices were -- U.S. investors had to overcome an 11% loss for anything
priced in the South African rand. The gap in interest rates between South Africa
and the United States, coupled with the concern about violence in neighboring
Zimbabwe, helped cause rand depreciation.

LOOKING AHEAD, WHAT IS YOUR OUTLOOK FOR THE NEXT SIX MONTHS?

     It is pretty much business as usual for us, but we are being much more
selective. The Federal Reserve has shaken things up with interest rate
increases. In a rising rate environment -- where any earnings shortfall tends to
be punished severely by the market -- sustainability is particularly important,
so we are rechecking our analysis very carefully and asking lots of tough
questions. This should help us manage our downside risk in the coming months.

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

[photo of Bradley Amoils and Henrik Strabo]

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

HOW DID GLOBAL GROWTH PERFORM DURING THE SIX MONTHS ENDED MAY 31, 2000?

     Global Growth performed well during this short but volatile time frame,
especially compared with its benchmark and peer group. The fund gained 15.16%,
far outdistancing the 1.90% return of its benchmark, the Morgan Stanley Capital
International World Free Index.*

     Similarly, the fund significantly outperformed most other global funds. The
264 global funds tracked by Lipper during the period posted an average return of
just 5.61%.

     Global Growth looks even more impressive from a longer-term perspective.
For the year ended May 31, 2000, the fund returned 61.77%, compared with just
13.56% for the index and a 23.29% average for 258 global funds tracked by Lipper
during this period.

BEFORE REVIEWING YOUR INVESTMENTS, COULD YOU OUTLINE THE KEYS TO YOUR INVESTMENT
APPROACH?

     We are growth investors. We focus on owning successful companies
experiencing strong growth that appears to be sustainable. To find these growing
businesses, we do a tremendous amount of fundamental analysis, much of it
involving face-to-face meetings with leaders of companies that appear to have
the growth characteristics we demand. In 1999, our international team, which
speaks a total of 13 languages, visited more than 1,400 companies.

     Importantly, we follow a "bottom-up" investment process, investing in
individual companies that meet our strict requirements, as opposed to targeting
sectors, industries, or even specific regions. We believe this approach enables
us to own the best possible set of companies at any given time.

TURNING TO YOUR PORTFOLIO, WHAT WERE SOME OF GLOBAL GROWTH'S MOST SUCCESSFUL
INVESTMENTS DURING THE PERIOD?

     Nortel Networks Corporation (up 46%) was one of our top contributors. The
Canadian company is a leading provider of fiber-optic technology for the
high-speed communications networks that businesses and consumers rely on to use
the Internet. In fact, the company estimates that its products carry more than
75% of North American Internet traffic. Nortel's earnings continue to be driven
by the rapid expansion of electronic commerce, which is requiring ever-greater
communications capacity on the Internet.

     Television Francais (up 91%) was another strong performer. The company
manages TF1, one of the most-watched television stations in France, and produces
news, drama, documentaries, sports, and children's programs. It also publishes
and distributes videocassettes, publishes and records music on tapes and CDs,
and operates a home shopping program. Television Francais recently joined
France's benchmark CAC index, gaining the attention of index-tracking funds. It
also benefited from

spending on TV advertising, which reached record levels in France during the
spring.

     Sonera Group Oyj (up more than 30%) is also a noteworthy holding. Finland's
biggest phone company, Sonera offers an array of fixed line and mobile voice,
video, and data services. Two out of three Finns own a cell phone, so it is not
surprising that Sonera was the first operator in the world to offer wireless
Internet service, making it possible for people to send and receive e-mails and
surf the Internet using their cellular handsets. It is now pioneering the
transformation of mobile phones into billing devices, whereby users can make
purchases by dialing numbers on their mobile phones (at "smart" vending
machines, for example), and pay the charges on their next phone bill.

FINANCIAL SERVICES REPRESENTS YOUR  SECOND-LARGEST SECTOR WEIGHTING.  WHAT'S
DRAWING YOU TO THAT AREA?

     The demand for financial products  is rapidly expanding in the United
States and abroad. In Europe particularly, citizens are taking a more proactive
role in their financial well-being--many for the first time--and are turning to
financial services firms for help. We've spread our investments among several
U.S. and international financial services companies. Domestically,  we own such
industry pacesetters as American Express, Citigroup Inc., and Charles Schwab &
Co. Inc.

     American Express is one of the leading global financial services companies.
The company has about 48 million credit cards in force worldwide, including its
new Blue Card, which contains an embedded computer chip. The card facilitates
purchases and payments online, a move to capture the business of younger,
technology-savvy consumers. It also appeals to those who perceive security on
the Internet as a major drawback to online transactions.

     Citigroup is a truly global financial services company. It provides a broad
range of financial products and services, the most prominent being consumer
banking and credit, and corporate and investment banking, to about 100 million
consumers, corporations, and institutions worldwide. The 1998 merger of Citicorp
and Travelers Group brought together such brand names as Citibank, Travelers,
Salomon Smith Barney, CitiFinancial, and Primerica under Citigroup's trademark.

     Charles Schwab is the biggest discount broker in the United States, and is
the epitome of an Internet-savvy company--half of its 7.1 million active
accounts are online, and the company's site is consistently rated among the best
for online trading. The San Francisco-based Schwab, which gets one of every five
trades done by online investors, is also moving toward global wireless delivery
of its financial services.

     In Europe, we continue to receive stellar performance from Sweden's Skandia
Forsakrings AB, one of our 10 largest positions, which gained 126% during the
six-month period. This company provides packaged financial services -- including
variable annuities, Web sites, and financial planning software -- for
independent financial advisors in 26 countries. In fact, the majority of its
profits come from annuity sales in the United States.

YOU HAVE MORE THAN A THIRD OF THE FUND  IN U.S. COMPANIES. WHAT ARE SOME OF YOUR
KEY INVESTMENTS THERE?

     One is a company called Enron Corp. based in Houston. This company is the
world's leading trader of gas and electricity. New markets for these commodities
have sprung up in the wake of the deregulation of utilities in the United States
and abroad over the last several years. The company will soon be trading another
commodity--broadband communications capacity. The company also provides energy
services--lighting, cooling, and electrical power to corporations and
institutions.

     We also own EMC Corporation, a company whose computer hardware helps keep
the Internet running. EMC is a leading provider of enterprise storage systems.
In effect, its technology ties together all of the computers and working parts
in a company's Web site, and stores the huge amounts of information companies
need to conduct business on the Internet. EMC's customers include companies like
Home Depot in the United States, Bertelsmann of Germany, and Korea Telecom. To
put the future demand for data storage in perspective, experts estimate that 96%
of the storage servers that will be deployed on the Internet by 2005 have yet to
be installed.

WHAT HOLDINGS DID NOT MEET YOUR  EXPECTATIONS?

     The spring meltdown in U.S. technology stocks rippled through the
international markets, and our exposure to some of the harder-hit companies
detracted from performance. Two former top-10 holdings are particularly notable
because they declined while representing a significant percentage of the
portfolio. One is Microsoft, and the other is America Online (AOL). Both stocks
were down close to 30% for the six months. Microsoft's recent legal woes are
well documented. AOL's outlook continues to be exciting, especially its pending
merger with media giant Time Warner.

     Of course, not all technology stocks posted negative returns. Despite
losing ground during the tech sell-off, top-10 holding Cisco Systems still
gained 28%.

WHAT ARE YOUR PLANS FOR GLOBAL GROWTH FOR THE NEXT SIX MONTHS?

     Although interest rate increases in the United States have raised the
degree of volatility and uncertainty in many global markets, it is still pretty
much business as usual for us. Our primary focus always remains on finding
companies, one at a time, that are demonstrating strong growth.

     In times of rising interest rates, companies that miss their earnings
estimates tend to be severely punished. That makes our insistence on a company's
ability to sustain its growth all the more important. With that in mind, we
check our holdings for any signs that their growth might be about to slow. We
believe this approach, applied with great discipline, will continue to reward
investors over time.

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

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

MAY 31, 2000 (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 (the 1940 Act) as an
open-end management investment 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 are
diversified under the 1940 Act. 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. The following significant
accounting policies are in accordance with generally accepted accounting
principles; these policies may require the use of estimates by fund management.

    MULTIPLE CLASS -- 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 for Global Growth had not commenced as of May 31, 2000.

    SECURITY VALUATIONS -- Portfolio securities traded primarily on a principal
securities exchange are valued at the last reported sales price, or at 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.

    Certain countries impose taxes on realized gains on the sale of their
securities. The funds record the foreign tax expense, if any, on an accrual
basis. The realized and unrealized tax provision reduces the net realized gain
(loss) on investments and net unrealized appreciation (depreciation) on
investments, respectively.

    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.

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

    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.

    At November 30, 1999, Emerging Markets had accumulated net realized capital
loss carryovers for federal income tax purposes of $864,075 (expiring in 2005
through 2006) which may be used to offset future taxable gains.

    ADDITIONAL INFORMATION -- Funds Distributor, Inc. (FDI) is a distributor of
the corporation. Certain officers of FDI are also officers of the corporation.

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

    The corporation has entered into a Management Agreement with ACIM, under
which ACIM 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 1940 Act (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 1940
Act. 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 six months ended May 31, 2000, were $265,100, $1,011, $896, and $565
for International Growth, International Discovery, Emerging Markets and Global
Growth, respectively.

statistics for each reporting period, including TOTAL RETURN, INCOME RATIO (net
income as a percentage of average net assets), EXPENSE RATIO (operating expenses
as a percentage of average net assets), and PORTFOLIO TURNOVER (a gauge of the
fund's trading activity).

This table itemizes investment results and distributions on a per-share basis to
illustrate share price changes for each of the last five fiscal years (or less,
if the share class is not five years old). It also includes several key
statistics for each reporting period, including TOTAL RETURN, INCOME RATIO (net
income as a percentage of average net assets), EXPENSE RATIO (operating expenses
as a percentage of average net assets), and PORTFOLIO TURNOVER (a gauge of the
fund's trading activity).

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 tax 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

INVESTMENT PHILOSOPHY AND POLICIES

     American Century offers 14 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
small- to medium-sized foreign companies. To enable the fund to maintain its
emphasis on small- to medium-sized growth companies, the fund closed to new
investors on January 28, 2000. We continue to accept investments into existing
accounts. 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 or 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 located primarily 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 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 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 represents the performance of stocks in developed
market countries (including the United States) that are available for purchase
by global investors.

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 42-52.

INVESTMENT TERMS

* 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.

* PRICE/BOOK RATIO-- a stock value measurement calculated by dividing a
company's stock price by its book value per share, with the result expressed as
a multiple instead of as a percentage. (Book value per share is calculated by
subtracting a company's liabilities from its assets, then dividing that value by
the number of outstanding shares.)

* PRICE/EARNINGS (P/E) RATIO-- a stock value measurement calculated by dividing
a company's stock price by its earnings per share, with the result expressed as
a multiple instead of as a percentage. (Earnings per share is calculated by
dividing the after-tax earnings of a corporation by its outstanding shares.)

TYPES OF STOCKS

* BLUE CHIP STOCKS-- stocks of the most established companies in American
industry. They are generally large, fairly stable companies that have
demonstrated consistent earnings and usually have long-term growth potential.
Examples include General Electric and Coca-Cola.

* 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, health
care and consumer staple companies.

* LARGE-CAPITALIZATION ("LARGE-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of more
than $9.2 billion. This is Lipper's market capitalization breakpoint as of May
31, 2000, although it may be subject to change based on market fluctuations. The
Dow Jones Industrial Average and the S& P 500 Index generally consist of stocks
in this range.

* MEDIUM-CAPITALIZATION ("MID-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of
between $2.2 billion and $9.2 billion. This is Lipper's market capitalization
breakpoint as of May 31, 2000, although it may be subject to change based on
market fluctuations. The S&P 400 Index and Russell 2500 Index generally consist
of stocks in this range.

* SMALL-CAPITALIZATION ("SMALL-CAP") STOCKS-- the stocks of companies with a
market capitalization (the total value of a company's outstanding stock) of less
than $2.2 billion. This is Lipper's market capitalization breakpoint as of May
31, 2000, although it may be subject to change based on market fluctuations. The
S&P 600 Index and the Russell 2000 Index generally consist of stocks in this
range.

* VALUE STOCKS-- generally considered to be stocks that are purchased because
they are relatively inexpensive. These stocks are typically characterized by low
P/E ratios.

FUND CLASSIFICATIONS

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

INVESTMENT OBJECTIVE

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

* 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 correspondingly 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.

* 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
correspondingly high price-fluctuation risk.

conservative, dependable way to invest for a specific time horizon.
