International Growth - Portfolio Commentary

[photo of investment team]

PORTFOLIO MANAGERS ON THE INTERNATIONAL GROWTH INVESTMENT TEAM: KEITH CREVELING
AND MICHAEL PERELSTEIN.

International Growth gained 12.09%* during the 12 months ended November 30,
2005, while its benchmark, the Morgan Stanley Capital International (MSCI) EAFE
Index, returned 13.25%.

Many of the world's equity markets advanced during the past fiscal year,
demonstrating resilience in the face of surging prices for oil and other
commodities, a terrorist attack in London, destructive hurricanes and eight
interest-rate increases by the U.S. Federal Reserve.

In this environment, our investments in a wide variety of companies boosted
total return during the fiscal year, with the portfolio benefiting from banks,
construction companies, retailers and some of the world's largest oil companies.
The gains came despite the movement of the dollar during the period, which
reduced our return. Relative to the MSCI EAFE Index, International Growth's
consumer discretionary sector contributed most. But several sectors, notably
consumer staples, underperformed the index, ultimately causing the portfolio to
lag the benchmark.

FINANCIALS, INDUSTRIALS BOOST RETURN

All of the sectors in which we were invested advanced, with financial holdings,
the portfolio's heaviest sector stake on average, posting the largest
contribution to absolute return. France's Societe Generale and Ireland's Anglo
Irish Bank Company were among the companies contributing to total return.
Elsewhere in the sector, we benefited from French insurance company Axa and
Japan's ORIX Corp., a financial services company.

International Growth's industrials sector made the second-largest contribution
to return, and outperformed the MSCI EAFE Index. Two companies in the
construction and engineering industry led the advance--Grupo Ferrovial SA, one
of Spain's largest construction companies, and Vinci SA, a French construction
company.

International Growth - Portfolio Commentary

MIXED RESULTS FROM CONSUMERS

International Growth's holdings in the consumer discretionary sector
outperformed the MSCI EAFE Index, making the largest contribution to our
relative performance. The portfolio's overweight position in Japanese
electronics retailer Yamada Denki led the sector's performance. Yamada Denki
contributed more than any other security to relative performance, and also
contributed most to absolute return.

The consumer discretionary sector, however, also included the position that
detracted more than any other security from the portfolio's relative
performance, Next Plc. One of the largest clothing retailers in the United
Kingdom, Next declined partly because of a slump in consumer spending in the
U.K. That slowdown also impacted U.K. supermarket giant Tesco, which was among
the biggest detractors in consumer staples, the sector that hurt our relative
performance most.

ENERGY ADVANCES, OUTPERFORMS

International Growth's position in the energy sector also contributed to the
portfolio's return, and outperformed the MSCI EAFE Index. Two of the portfolio's
largest positions, France's Total and the United Kingdom's BP, both contributed
to return during the period. The portfolio's relative performance also benefited
from an overweight position in the energy equipment and services industry.

OUTLOOK

Although small companies continued to outperform large during the period, and
value again topped growth, we believe changes are on the horizon. We are basing
our outlook on a variety of fundamental factors and economic developments,
including a rising interest-rate environment that historically has tended to
favor large-growth corporations, the attractive valuations for growth compared
to value, and the likely outperformance of large companies during the latter
stages of an economic recovery. These signs suggest we are entering a period
that may favor the large, growing companies in which International Growth
invests.

Shareholder Fee Example (Unaudited)

Fund shareholders may incur two types of costs: (1) transaction costs, including
sales charges (loads) on purchase payments and redemption/exchange fees; and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in your fund and to compare these costs
with the ongoing cost of investing in other mutual funds.

The example is based on an investment of $1,000 made at the beginning of the
period and held for the entire period from June 1, 2005 to November 30, 2005.

ACTUAL EXPENSES

The table provides information about actual account values and actual expenses
for each class. You may use the information, together with the amount you
invested, to estimate the expenses that you paid over the period. First,
identify the share class you own. Then simply divide your account value by
$1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number under the heading "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond Fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
American Century may charge you a $12.50 semiannual account maintenance fee if
the value of those shares is less than $10,000. We will redeem shares
automatically in one of your accounts to pay the $12.50 fee. In determining your
total eligible investment amount, we will include your investments in all
PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered
under your Social Security number. PERSONAL ACCOUNTS include individual
accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell
Education Savings Accounts and IRAs (including traditional, Roth, Rollover,
SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you
have only business, business retirement, employer-sponsored or American Century
Brokerage accounts, you are currently not subject to this fee. We will not
charge the fee as long as you choose to manage your accounts exclusively online.
If you are subject to the Account Maintenance Fee, your account value could be
reduced by the fee amount.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The table also provides information about hypothetical account values and
hypothetical expenses based on the actual expense ratio of each class of your
fund and an assumed rate of return of 5% per year before expenses, which is not
the actual return of a fund's share class. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in your fund and other funds. To do so, compare this
5% hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

Shareholder Fee Example (Unaudited)

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption/exchange fees. Therefore, the table is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

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 (the fund) is
one fund in a series issued by the corporation. The fund is diversified under
the 1940 Act. The fund's investment objective is to seek capital growth. The
fund pursues its objective by investing primarily in equity securities of
foreign companies in developed countries. The following is a summary of the
fund's significant accounting policies.

MULTIPLE CLASS -- The fund is authorized to issue the Investor Class, the
Institutional Class, the Advisor Class, the A Class, the B Class, the C Class
and the R Class. The A Class may incur an initial sales charge. The A Class, B
Class and C Class may be subject to a contingent deferred sales charge. The
share classes differ principally in their respective sales charges and
shareholder servicing and distribution expenses and arrangements. All shares of
the 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. Income, non-class specific expenses, and realized and unrealized
capital gains and losses of the fund are allocated to each class of shares based
on their relative net assets.

SECURITY VALUATIONS -- 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. Depending on
local convention or regulation, securities traded over-the-counter are valued at
the mean of the latest bid and asked prices, the last sales price, or the
official close price. Debt securities not traded on a principal securities
exchange are valued through a commercial pricing service or at the mean of the
most recent bid and asked prices. Discount notes may be valued through a
commercial pricing service or at amortized cost, which approximates fair value.
If the fund determines that the market price of a portfolio security is not
readily available, or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued at its fair value as
determined by, or in accordance with procedures adopted by, the Board of
Directors or its designee if such fair value determination would materially
impact a fund's net asset value. Circumstances that may cause the fund to fair
value a security include: an event occurred after the close of the exchange on
which a portfolio security principally trades (but before the close of the New
York Stock Exchange) that was likely to have changed the value of the security;
a security has been declared in default; or trading in a security has been
halted during the trading day.

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 securities registered in their country.
The fund records the foreign tax expense, if any, on an accrual basis. The
realized and unrealized tax provision reduces the net realized gain (loss) on
investment transactions 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.

SECURITIES ON LOAN -- The fund may lend portfolio securities through its lending
agent to certain approved borrowers in order to earn additional income. The fund
continues to recognize any gain or loss in the market price of the securities
loaned and records any interest earned or dividends declared.

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. Certain countries may impose taxes on the contract amount of
purchases and sales of foreign currency contracts in their currency. The fund
records the foreign tax expense, if any, as a reduction to the net realized gain
(loss) on foreign currency transactions.

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

REPURCHASE AGREEMENTS -- The fund may enter into repurchase agreements with
institutions that 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 fund requires that
the collateral, represented by securities, received in a repurchase transaction
be transferred to the custodian in a manner sufficient to enable the fund to
obtain those securities in the event of a default under the repurchase
agreement. ACIM monitors, on a daily basis, the securities transferred to ensure
the value, including accrued interest, of the securities under each repurchase
agreement is equal to or greater than amounts owed to the fund under each
repurchase agreement.

JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities
and Exchange Commission, the fund, along with other registered investment
companies having management agreements with ACIM or American Century Global
Investment Management, Inc. (ACGIM), 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 fund's policy to distribute substantially all net
investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under 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, if any, are
generally declared and paid annually. Distributions from net realized gains, if
any, are generally declared and paid twice per year.

REDEMPTION -- The fund may impose a 2% redemption fee on shares held less than
60 days. The fee may not be applicable to all classes. The redemption fee is
recorded as a reduction in the cost of shares redeemed. The redemption fee is
retained by the fund and helps cover transaction costs that long-term investors
may bear when a fund sells securities to meet investor redemptions.

INDEMNIFICATIONS -- Under the corporation's organizational documents, its
officers and directors are indemnified against certain liabilities arising out
of the performance of their duties to the fund. In addition, in the normal
course of business, the fund enters into contracts that provide general
indemnifications. The fund's maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the fund.
The risk of material loss from such claims is considered by management to be
remote.

USE OF ESTIMATES -- The financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require management to make certain estimates and assumptions at the date of
the financial statements. Actual results could differ from these estimates.

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

MANAGEMENT FEES -- The corporation has entered into a Management Agreement with
ACGIM (the investment advisor), under which ACGIM provides the fund with
investment advisory and management services in exchange for a single, unified
management fee (the fee) per class. The Agreement provides that all expenses of
the fund, 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
ACGIM. The fee is computed and accrued daily based on the daily net assets of
the specific class of shares of the fund and paid monthly in arrears. For funds
with a stepped fee schedule, the rate of the fee is determined by applying a fee
rate calculation formula. This formula takes into account all of the investment
advisor's assets under management in the fund's investment strategy (strategy
assets) to calculate the appropriate fee rate for the fund. The strategy assets
include the fund's assets and the assets of other clients of the investment
advisor that are not in the American Century family of funds, but that have the
same investment team and investment strategy.

The annual management fee schedule for each class of the fund is as follows:

--------------------------------------------------------------------------------
                            INVESTOR,
                           A, B, C & R       INSTITUTIONAL         ADVISOR
--------------------------------------------------------------------------------
STRATEGY ASSETS
--------------------------------------------------------------------------------
First $1 billion              1.50%              1.30%              1.25%
--------------------------------------------------------------------------------
Next $1 billion               1.20%              1.00%              0.95%
--------------------------------------------------------------------------------
Over $2 billon                1.10%              0.90%              0.85%
--------------------------------------------------------------------------------

The effective annual management fee for the fund for the year ended November 30,
2005 was 1.23% for the Investor Class, A Class, B Class, C Class and R Class,
and 1.03% and 0.98% for the Institutional Class and Advisor Class, respectively.

ACGIM has entered into a Subadvisory Agreement with ACIM (the investment
subadvisor) on behalf of the fund. The subadvisor makes investment decisions for
the cash portion of the fund in accordance with the fund's investment
objectives, policies and restrictions under the supervision of ACGIM and the
Board of Directors. ACGIM pays all costs associated with retaining ACIM as the
subadvisor of the fund.

DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master
Distribution and Shareholder Services Plan for the Advisor Class (the Advisor
Class plan) and a separate Master Distribution and Individual Shareholder
Services Plan for each of the A Class, B Class, C Class and R Class
(collectively with the Advisor Class Plan, the plans), pursuant to Rule 12b-1 of
the 1940 Act. The plans provide that the Advisor Class, B Class and C Class will
pay American Century Investment Services, Inc. (ACIS) the following annual
distribution and service fees:

--------------------------------------------------------------------------------
                                       ADVISOR                   B & C
--------------------------------------------------------------------------------
Distribution Fee                        0.25%                    0.75%
--------------------------------------------------------------------------------
Service Fee                             0.25%                    0.25%
--------------------------------------------------------------------------------

The plans provide that the A Class and the R Class will pay ACIS an annual
distribution and service fee of 0.25% and 0.50%, respectively. The fees are
computed and accrued daily based on each class's daily net assets and paid
monthly in arrears. The distribution fee provides compensation for expenses
incurred in connection with distributing shares of the classes including, but
not limited to, payments to brokers, dealers, and financial institutions that
have entered into sales agreements with respect to shares of the fund. The
service fee provides compensation for shareholder and administrative services
rendered by ACIS, its affiliates or independent third party providers for
Advisor Class shares and for individual shareholder services rendered by
broker/dealers or other independent financial intermediaries for A, B, C and R
Class shares.

During the year ended November 30, 2005, the R Class received reimbursements of
its distribution and service fees of $459 ($ in full).

Fees incurred under the plans during the year ended November 30, 2005, are
detailed in the Statement of Operations.

Notes to Financial Statements

NOVEMBER 30, 2005 (AMOUNTS IN THOUSANDS)

5. SECURITIES LENDING

As of November 30, 2005, securities in the fund valued at $517,907 were on loan
through the lending agent, JPMCB, to certain approved borrowers. JPMCB receives
and maintains collateral in the form of cash, and/or acceptable securities as
approved by ACIM or ACGIM. Cash collateral is invested in authorized investments
by the lending agent in a pooled account. The value of cash collateral received
at period end is disclosed in the Statement of Assets and Liabilities and
investments made with the cash by the lending agent are listed in the Schedule
of Investments. Any deficiencies or excess of collateral must be delivered or
transferred by the member firms no later than the close of business on the next
business day. The total value of all collateral received, at this date, was
$544,718. The fund's risks in securities lending are that the borrower may not
provide additional collateral when required or return the securities when due.
If the borrower defaults, receipt of the collateral by the fund may be delayed
or limited.

6. BANK LINE OF CREDIT

The fund, along with certain other funds managed by ACIM or ACGIM, has a $575
million unsecured bank line of credit agreement with JPMCB, which was renewed to
$500 million effective December 14, 2005. The fund may borrow money for
temporary or emergency purposes to fund shareholder redemptions. Borrowings
under the agreement bear interest at the Federal Funds rate plus 0.50%. The fund
did not borrow from the line during the year ended November 30, 2005.

7. RISK FACTORS

There are certain risks involved in investing in foreign securities. These risks
include those resulting from future adverse political, social, and economic
developments, fluctuations in currency exchange rates, the possible imposition
of exchange controls, and other foreign laws or restrictions.

8. FEDERAL TAX INFORMATION

On December 13, 2005, each class of the fund declared and paid the following
per-share ordinary income distribution to shareholders of record on December 12,
2005.

--------------------------------------------------------------------------------
      INVESTOR      INSTITUTIONAL      ADVISOR & A       B & C         R

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

The tax character of distributions paid during the years ended November 30, 2005
and November 30, 2004 were as follows:

--------------------------------------------------------------------------------
                                                            2005       2004

DISTRIBUTIONS PAID FROM

Long-term capital gains                                       --         --
--------------------------------------------------------------------------------

The book-basis 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 on the financial statements.

8. FEDERAL TAX INFORMATION (CONTINUED)

As of November 30, 2005, the components of distributable earnings on a tax-basis
and the federal tax cost of investments were as follows:

--------------------------------------------------------------------------------
COMPONENTS OF DISTRIBUTABLE EARNINGS AND TAX COST
--------------------------------------------------------------------------------
Federal tax cost of investments                                      $2,832,070
================================================================================
Gross tax appreciation of investments                                  $512,754
------------------------------------------------------------------
Gross tax depreciation of investments                                   (11,008)
--------------------------------------------------------------------------------
Net tax appreciation (depreciation) of investments                     $501,746
================================================================================
Net tax appreciation (depreciation) on derivatives
and translation of assets and
liabilities in foreign currencies                                           (26)
--------------------------------------------------------------------------------
Net tax appreciation (depreciation)                                    $501,720
================================================================================
Undistributed ordinary income                                           $46,625
------------------------------------------------------------------
Accumulated capital losses                                            $(847,746)
------------------------------------------------------------------
Currency loss deferral                                                    $(125)
--------------------------------------------------------------------------------

The difference between book-basis and tax-basis cost and unrealized appreciation
(depreciation) is attributable primarily to the tax deferral of losses on wash
sales and on investments in passive foreign investment companies.

The accumulated capital losses listed above represent net capital loss
carryovers that may be used to offset future realized capital gains for federal
income tax purposes. Capital loss carryovers of $(152,830), $(637,150), and
$(57,766) which expire in 2009, 2010, and 2011, respectively.

The currency loss deferral represents net foreign currency losses incurred in
the one-month period ended November 30, 2005. The fund has elected to treat such
losses as having been incurred in the following fiscal year for federal income
tax purposes.

9. OTHER TAX INFORMATION (UNAUDITED) ($ IN FULL)

The following information is provided pursuant to provisions of the Internal
Revenue Code.

The fund hereby designates $36,676,044 of qualified dividend income for the
fiscal year ended November 30, 2005.

As of November 30, 2005, International Growth designates $4,315,686 as a foreign

    gains distributions, if any. Total returns for periods less than one year
    are not annualized. The total return of the classes may not precisely
    reflect the class expense differences because of the impact of calculating
    the net asset values to two decimal places. If net asset values were
    calculated to three decimal places, the total return differences would more
    closely reflect the class expense differences. The calculation of net asset
    values to two decimal places is made in accordance with SEC guidelines and
    does not result in any gain or loss of value between one class and another.

(4) During the year ended November 30, 2005, the class received a partial
    reimbursement of its distribution and service fees. Had fees not been
    reimbursed, the ratio of operating expenses to average net assets and the
    ratio of net investment income to average net assets would have been 1.73%
    and 0.72%, respectively.

    was calculated for the year ended November 30, 2003.

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of International Growth Fund, (the "Fund"), one of
the mutual funds comprising American Century World Mutual Funds, Inc., as of
November 30, 2005, and the related statement of operations for the year then
ended, the statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for the periods presented. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Fund
is not required to have, nor were we engaged to perform, an audit of its
internal control over financial reporting. Our audit included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Fund's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of November 30, 2005, by correspondence with the
custodian and brokers; where replies were not received from brokers. We believe
that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of
International Growth Fund as of November 30, 2005, the results of its operations
for the year then ended, the changes in its net assets for each of the two years
in the period then ended, and the financial highlights for the periods
presented, in conformity with accounting principles generally accepted in the
United States of America.

Management

The individuals listed below serve as directors or officers of the fund. Each
director serves until his or her successor is duly elected and qualified or
until he or she retires. Mandatory retirement age for independent directors is
72. Those listed as interested directors are "interested" primarily by virtue of
their engagement as officers of American Century Companies, Inc. (ACC) or its
wholly owned, direct or indirect, subsidiaries, including the fund's investment
advisor, American Century Global Investment Management, Inc. (ACGIM) or American
Century Investment Management, Inc. (ACIM); the fund's principal underwriter,
American Century Investment Services, Inc. (ACIS); and the fund's transfer
agent, American Century Services, LLC (ACS LLC).

The other directors (more than three-fourths of the total number) are
independent; that is, they have never been employees or officers of, and have no
financial interest in, ACC or any of its wholly-owned subsidiaries, including
ACGIM, ACIM, ACIS, and ACS LLC. The directors serve in this capacity for six
registered investment companies in the American Century family of funds.

All persons named as officers of the fund also serve in a similar capacity for
the other 13 investment companies advised by ACIM or ACGIM, unless otherwise
noted. Only officers with policy-making functions are listed. No officer is
compensated for his or her service as an officer of the fund. The listed
officers are interested persons of the fund and are appointed or re-appointed on
an annual basis. The information below is provided as of December 15, 2005.

Approval of Management Agreement for International Growth

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors (the "Directors") each year. At
American Century, this process -- referred to as the "15(c) Process" -- involves
at least two board meetings spanning a 30 to 60 day period each year. In
addition to this annual review, the board of directors oversees and evaluates on
a continuous basis at its quarterly meetings the nature and quality of
significant services the advisor performs on behalf of the fund. At these
meetings the board reviews fund performance, shareholder services, audit and
compliance information, and a variety of other reports from the advisor
concerning fund operations. The board, or committees of the board, also hold
special meetings, as needed.

Under a new Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for its board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year, the Directors requested and received extensive data and information
compiled by the advisor and certain independent providers of evaluative data
(the "15(c) Providers") concerning the fund and the services provided to such
fund under the management agreement. The information included, but was not
limited to:

* the nature, extent and quality of investment management, shareholder
  services and other services provided to the fund under the management
  agreement;

* reports on the advisor's activities relating to the wide range of
  programs and services the advisor provides to the fund and its shareholders
  on a routine and non-routine basis;

* data comparing the cost of owning the fund to the cost of owning
  similar funds;

* data comparing the fund's performance to appropriate benchmarks
  and/or a peer group of other mutual funds with similar investment
  objectives and strategies;

* financial data showing the profitability of the fund to the advisor
  and the overall profitability of the advisor; and

* data comparing services provided and charges to other investment
  management clients of the advisor.

In keeping with its practice, the fund's board of directors held two regularly
scheduled meetings and one special meeting to review and discuss the information
provided by the advisor and to complete its negotiations with the advisor
regarding the renewal of the management agreement, including the setting of the
applicable advisory fee. In addition, the independent directors met on several
occasions in private session to review and discuss the information provided and
evaluate the advisor's performance as manager of the fund.

Approval of Management Agreement for International Growth

FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor and the
15(c) Providers and evaluated such information for each fund managed by the
advisor. The Directors did not identify any single factor as being all-important
or controlling, and each Director may have attributed different levels of
importance to different factors. In deciding to renew the agreement, the
Directors' decision was based on the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the fund. The board noted that under the
management agreement, the advisor provides or arranges at its own expense a wide
variety of services including, but not limited to:

* fund construction and design

* portfolio security selection

* initial capitalization/funding

* securities trading

* custody of fund assets

* daily valuation of the fund's portfolio

* shareholder servicing and transfer agency, including shareholder
  confirmations, recordkeeping and communications

* legal services

* regulatory and portfolio compliance

* financial reporting

* marketing and distribution

The Directors noted that many of these services have expanded over time both in
terms of quantity and complexity in response to shareholder demands, competition
in the industry and the regulatory environment. In performing their evaluation,
the Directors considered information received in connection with the annual
review, as well as information provided on an ongoing basis at their regularly
scheduled board meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services
provided is quite complex and allows fund shareholders access to professional
money management, instant diversification of their investments within an asset
class, the opportunity to easily diversify among asset classes, and liquidity.
In evaluating investment performance, the board expects the advisor to manage
the fund in accordance with its investment objective and approved strategies. In
providing these services, the advisor utilizes teams of investment professionals
(portfolio managers, analysts, research assistants, and securities traders) who
require extensive information technology, research, training, compliance and
other systems to conduct their business. At each quarterly meeting the Directors
review investment performance information for the fund, together with
comparative information for appropriate benchmarks and a peer group of funds
managed similarly to the fund. If performance concerns are identified, the
Directors discuss with the advisor the reasons for such results (e.g., market
conditions, stock selection) and any efforts being undertaken to improve
performance. Annually, the Directors review detailed performance information, as
provided by the 15(c) Providers, comparing the fund's performance with that of
similar funds not managed by

(continued)


------
35


Approval of Management Agreement for International Growth

the advisor. The fund's performance was below the median of its peer groups for
both the one and three year periods during the past year. The Directors
discussed the fund's performance with the advisor and were satisfied with the
efforts being undertaken by the advisor. The Directors will continue to monitor
those efforts and the performance of the fund.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the fund with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at its regular
quarterly meetings, including the annual meeting concerning contract review.
These reports include, but are not limited to, information regarding the
operational efficiency and accuracy of the shareholder and transfer agency
services provided, staffing levels, shareholder satisfaction (as measured by
external as well as internal sources), technology support, new products and
services offered to fund shareholders, securities trading activities, portfolio
valuation services, auditing services, and legal and operational compliance
activities. Certain aspects of shareholder and transfer agency service level
efficiency and the quality of securities trading activities are measured by
independent third party providers and are presented in comparison to other fund
groups not managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various services
to the fund, its profitability in managing the fund, its overall profitability,
and its financial condition. The Directors have reviewed with the advisor the
methodology used to prepare this financial information. This financial
information regarding the advisor is considered in order to evaluate the
advisor's financial condition, its ability to continue to provide services under
the management agreement, and the reasonableness of the current management fee.

ETHICS OF THE ADVISOR. The Directors generally considered the advisor's
commitment to providing quality services to shareholders and to conducting its
business ethically. They noted that the advisor's practices generally meet or
exceed industry best practices and that the advisor was not implicated in the
industry scandals of 2003 and 2004.

ECONOMIES OF SCALE. The Directors reviewed reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes in
revenue, costs, and profitability. The Directors concluded that economies of
scale are difficult to measure and predict overall, and particularly on a
fund-by-fund basis. This analysis is also complicated by the additional services
and content provided by the advisor and its reinvestment in its ability to
provide and expand those services. Accordingly, the Directors seek to evaluate
economies of scale by reviewing other information, such as year-over-year
profitability of the advisor generally, the profitability of its management of
the fund specifically, and the breakpoint fees of competitive funds not managed
by the advisor over a range of asset sizes. The Directors believe the advisor is
appropriately sharing any economies of scale through

(continued)


------
36


Approval of Management Agreement for International Growth

its competitive fee structure, fee breakpoints as the fund increases in size,
and through reinvestment in its business to provide shareholders additional
content and services.

COMPARISON TO OTHER FUNDS' FEES. The fund pays the advisor a single,
all-inclusive (or unified) management fee for providing all services necessary
for the management and operation of the fund, other than brokerage expenses,
taxes, interest, extraordinary expenses, and the fees and expenses of the fund's
independent directors (including their independent legal counsel). Under the
unified fee structure, the advisor is responsible for providing all investment
advisory, custody, audit, administrative, compliance, recordkeeping, marketing
and shareholder services, or arranging and supervising third parties to provide
such services. By contrast, most other fund groups are charged a variety of
fees, including an investment advisory fee, a transfer agency fee, an
administrative fee, distribution charges and other expenses. Other than their
investment advisory fees and Rule 12b-1 distribution fees, all other components
of the total fees charged by these other fund groups may be increased without
shareholder approval. The board believes the unified fee structure is a benefit
to fund shareholders because it clearly discloses to shareholders the cost of
owning fund shares, and, since the unified fee cannot be increased without a
vote of fund shareholders, it shifts to the advisor the increased costs of
operating the funds and the risk of administrative inefficiencies. Part of the
Directors' analysis of fee levels involves comparing the fund's unified fee to
the total expense ratio of other funds in a group of similar funds that was
compiled by a 15(c) Provider independent of the advisor (the "Peer Group"). The
unified fee charged to shareholders of the fund is below the median of the total
expense ratios of its Peer Group.

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services to
advisory clients other than the fund. They observed that these varying types of
client accounts require different services and involve different regulatory and
entrepreneurial risks than the management of the fund. The Directors analyzed
this information and concluded that the fees charged and services provided to
the fund were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the fund. They concluded that the advisor's primary business
is managing mutual funds and it generally does not use the fund or shareholder
information to generate profits in other lines of business, and therefore does
not derive any significant collateral benefits from them. The Directors noted
that the advisor receives proprietary research from broker dealers that execute
fund portfolio transactions and concluded that this research is likely to
benefit fund shareholders. The Directors also determined that the advisor is
able to provide investment management services to clients other than the fund,

(continued)

37


Approval of Management Agreement for International Growth

at least in part, due to its existing infrastructure built to serve the fund
complex. The Directors concluded, however, that the assets of those other
clients are not material to the analysis and in any event are added to the
assets of the funds within the fund complex that use substantially the same
investment management team to determine whether the fund has reached breakpoints
in its fee schedule.

CONCLUSIONS OF THE DIRECTORS

As a result of this process, the independent directors, in the absence of
particular circumstances and assisted by the advice of legal counsel that is
independent of the advisor, taking into account all of the factors discussed
above and the information provided by the advisor, concluded that the investment
management agreement between the fund and the advisor is fair and reasonable in
light of the services provided and should be renewed.

Share Class Information

Seven classes of shares are authorized for sale by International Growth:
Investor Class, Institutional Class, Advisor Class, A Class, B Class, C Class,
and R Class. The total expense ratio of Institutional Class shares is lower than
that of Investor Class shares. The total expense ratios of Advisor, A, B, C, and
R Class shares are higher than that of Investor Class shares.

INVESTOR CLASS shares are available for purchase in two ways: 1) directly from
American Century without any commissions or other fees; or 2) through certain
financial intermediaries (such as banks, broker-dealers, insurance companies and
investment advisors), which may require payment of a transaction fee to the
financial intermediary.

INSTITUTIONAL CLASS shares are available to large investors such as endowments,
foundations, and retirement plans, and to financial intermediaries serving these
investors. This class recognizes the relatively lower cost of serving
institutional customers and others who invest at least $5 million ($3 million
for endowments and foundations) 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 unified management fee
of Institutional Class shares is 0.20% less than the unified management fee of
Investor Class shares.

ADVISOR CLASS shares are sold primarily through institutions such as investment
advisors, banks, broker-dealers, insurance companies, and financial advisors.
Advisor Class shares are subject to a 0.50% annual Rule 12b-1 service and
distribution fee. The total expense ratio of Advisor Class shares is 0.25%
higher than the total expense ratio of Investor Class shares.

A CLASS shares are sold primarily through employer-sponsored retirement plans
and through institutions such as investment advisors, banks, broker-dealers, and
insurance companies. A Class shares are sold at their offering price, which is
net asset value plus an initial sales charge that ranges from 5.75% to 0.00% for
equity funds, depending on the amount invested. The initial sales charge is
deducted from the purchase amount before it is invested. A Class shares may be
subject to a contingent deferred sales charge (CDSC). There is no CDSC on shares
acquired through reinvestment of dividends or capital gains. The prospectus
contains information regarding reductions and waivers of sales charges for A
Class shares. The unified management fee for A Class shares is the same as for
Investor Class shares. A Class shares also are subject to a 0.25% annual Rule
12b-1 service and distribution fee.

Share Class Information

B CLASS shares are sold primarily through employer-sponsored retirement plans
and through institutions such as investment advisors, banks, broker-dealers, and

Additional Information

RETIREMENT ACCOUNT INFORMATION

As required by law, any distributions you receive from an IRA or certain 403(b),
457 and qualified plans [those not eligible for rollover to an IRA or to another
qualified plan] are subject to federal income tax withholding, unless you elect
not to have withholding apply. Tax will be withheld on the total amount
withdrawn even though you may be receiving amounts that are not subject to
withholding, such as nondeductible contributions. In such case, excess amounts
of withholding could occur. You may adjust your withholding election so that a
greater or lesser amount will be withheld.

If you don't want us to withhold on this amount, you must notify us to not
withhold the federal income tax. 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 notice not to withhold federal
income tax prior to the withdrawal. You may notify us in writing or in certain
situations by telephone or through other electronic means. You have the right to
revoke your withholding election at any time and any election you make may
remain in effect until revoked by filing a new election.

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.

State tax will be withheld if, at the time of your distribution, your address is
within one of the mandatory withholding states and you have federal income tax
withheld. State taxes will be withheld from your distribution in accordance with
the respective state rules.

International Stock - Portfolio Commentary

[photo of investment team]

PORTFOLIO MANAGERS ON THE INTERNATIONAL STOCK INVESTMENT TEAM:
KEITH CREVELING AND MICHAEL PERELSTEIN.

International Stock gained 8.40%* since its inception March 31, 2005, through
November 30, 2005, while its benchmark, the Morgan Stanley Capital International
(MSCI) EAFE Index, returned 8.67%.

Many of the world's equity markets advanced during the period, demonstrating
resilience in the face of surging prices for commodities, especially oil, a
terrorist attack in London, destructive hurricanes and numerous interest-rate
increases by the U.S. Federal Reserve.

In this environment, all of the sectors in which International Stock was
invested contributed to total return. The gains came despite the movement of the
dollar, which diminished our return. On a relative basis, International Stock's
investments in a variety of sectors outperformed the MSCI EAFE Index, led by
holdings in the consumer discretionary sector. Consumer staples detracted most
from relative performance.

BANKS BOOST RETURN

The financials sector contributed most to absolute return, led by International
Stock's stake in the commercial banks industry. France's Societe Generale and
the National Bank of Greece were among the largest contributors. Societe
Generale benefited from increased earnings in its corporate and investment
banking division, while the National Bank of Greece reported during the period
that net income rose 62% to $396.4 million during the first half of 2005 versus
the same period a year earlier on strong demand for loans.

Holdings in the insurance and consumer finance industries also benefited the
portfolio, with French insurance company Axa and Japan's ORIX Corp., a global
financial services company, among the securities making the largest
contributions to the sector's return. The portfolio's financial holdings
detracted slightly from our relative performance.

MIXED RESULTS FROM CONSUMERS

International Stock's holdings in the consumer discretionary sector outperformed
the MSCI EAFE Index, making

International Stock - Portfolio Commentary

the largest contribution to our relative performance. The portfolio's overweight
position in Japanese electronics retailer Yamada Denki led the sector's
performance. Yamada Denki, which benefited from strong sales of flat-panel
televisions, contributed more than any other security to relative performance,
and also contributed most to absolute return.

The consumer discretionary sector, however, also included Next Plc, which
detracted significantly from the portfolio's relative and absolute performance.
One of the largest clothing retailers in the United Kingdom, Next declined
partly because of a slump in consumer spending in the U.K. That slowdown also
impacted U.K. supermarket giant Tesco, which was among the biggest detractors in
consumer staples, the sector that hurt our relative performance most.

LIFT FROM ENERGY

International Stock's position in the energy sector also contributed to the
portfolio's return, and outperformed the MSCI EAFE Index. Two of the portfolio's
largest positions, France's Total and the United Kingdom's BP, both contributed
to return.

OUTLOOK

Although small companies continued to outperform large during the period, and
value again topped growth, we believe changes are on the horizon. We are basing
our outlook on a variety of fundamental factors and economic developments,
including a rising interest-rate environment that historically has tended to
favor large-growth corporations, the attractive valuations for growth compared
to value, and the likely outperformance of large companies during the latter
stages of an economic recovery. These signs suggest we are entering a period
that may favor the large, growing companies in which International Stock
invests.

International Discovery - Portfolio Commentary

[photo of investment team]

PORTFOLIO MANAGERS ON THE INTERNATIONAL DISCOVERY INVESTMENT TEAM:
BRIAN BRADY AND MARK KOPINSKI.

International Discovery gained 24.30%* during the one-year period ended November
30, 2005, outperforming its benchmark, the S&P/Citigroup EMI (Extended Market
Index) Growth World ex-US, which returned 19.21%. The portfolio's results also
were ahead of the 22.80% average return for its Morningstar Foreign Small/Mid
Growth peer group.** It's also worth noting that International Discovery
provided this positive performance despite a strengthening dollar that lowered
overseas returns for U.S. investors.

Many of the world's equity markets advanced during the period, demonstrating
their resilience in the face of surging oil and commodity prices, a terrorist
attack in London, destructive hurricanes and eight interest-rate increases by
the U.S. Federal Reserve. Against these backdrops, the majority of International
Discovery's sector stakes provided double-digit returns, with industrials,
information technology businesses and providers or sellers of consumer
discretionary products our top contributors.

Additionally, as the chart on page 10 indicates, we essentially doubled our
weighting in Japan since our last report to you six months ago. From our
perspective, a continuing economic recovery, coupled with years of corporate
restructuring and cost-cutting, have changed the earnings picture there
significantly. Many Japanese companies are reporting strong earnings, which has
played to our strength as bottom-up growth investors. A case in point was one of
our top contributors, Tokyo-based trading company Marubeni Corp. In October,
Marubeni reported its first-half results--a 58% increase in net income from a
year earlier.

SUCCESS IN INDUSTRIALS

Industrial stocks contributed the most to our results. Of note was Koninklijke
BAM Groep N.V., the largest Dutch builder, and one of our ten largest positions.
BAM benefited from rising property prices and increased earnings from
developments. The company also announced plans to acquire a major Dutch real

International Discovery - Portfolio Commentary

estate developer to increase its share of the Dutch homebuilding market.

Elsewhere in the sector, our shares of Motech Industries, a Taiwanese maker of
solar cells, performed well amid rising demand for solar panels from European
countries. Germany, for example, provides subsidies to companies and consumers
for using cleaner energy.

GAINS IN TECHNOLOGY

Our successes in the information technology sector included Taiwan's High Tech
Computer Corp. The company is a leading maker of advanced mobile phones powered
by Microsoft Corp. software, and exhibited the solid earnings acceleration we
look for. Its shares were up more than four-fold during the period. Foxconn
International Holdings, a leader in the contract manufacturing of mobile-phone
handsets, was another tech standout. Handset pricing pressure and a continuous
stream of new products have led handset vendors to increase their outsourcing.
Foxconn's major customers are Motorola and Nokia, prestigious brands with
substantial market share.

DETRACTORS INCLUDED CHEMICAL, IT STOCKS

On the downside, Nova Chemicals Corp., Canada's largest chemical maker,
detracted the most from our performance. We sold our shares after the company
reported net losses for the second and third quarters after wrestling with
declining prices, power outages and plant closings.

UTStarcom Inc. and Research In Motion Ltd. were two other disappointments.
U.S.-based UTStarcom, the largest supplier of wireless telephone systems in
China, has been challenged by a slowing market there. In March, UTStarcom
announced that it would have to restate earlier results due to accounting
problems. We sold our shares in April. In June, we moved out of Research In
Motion, the Canadian maker of the popular Blackberry email device, as the
company fought increasing competition.

Emerging Markets - Portfolio Commentary

[photo of investment team]

PORTFOLIO MANAGER ON THE EMERGING MARKETS INVESTMENT TEAM: MICHAEL DONNELLY.

Emerging Markets climbed 33.10%* during the 12 months ended November 30, 2005,
in line with its benchmark, the Morgan Stanley Capital International (MSCI) EM
(Emerging Markets) Index, which rose 33.13%. Emerging Markets performance during
the fiscal year compares favorably to that of its peers. The fund topped the
average 30.97% return of the diversified emerging markets funds tracked by
Morningstar.**

OVERSEAS MARKETS CLIMB

Many of the world's equity markets advanced during the 12-month period,
demonstrating their resilience in the face of surging prices for commodities,
especially oil, a terrorist attack in London, destructive hurricanes and
numerous interest-rate increases by the U.S. Federal Reserve. Emerging-markets
countries in particular continued to generate interest, a trend evidenced by the
142% gain of the MSCI EM Index since the end of 2002.

In that environment, Emerging Markets achieved positive absolute contributions
from the majority of its country exposures -- gains achieved despite the fact
that the movement of the dollar versus other currencies slightly slowed the
fund's performance.

SOUTH KOREA: THE TOP CONTRIBUTOR

Emerging Markets' interest in South Korea, on average our largest country
exposure, made the greatest contribution to absolute performance during the
fiscal year. Three of the top-contributing stocks from this country, Hynix
Semiconductor, Orion Corp., and Humax Co. Ltd., were represented in the
portfolio but not the index. During the period, Hynix, the world's
second-largest memory chipmaker, reported better-than-expected profits driven by
demand and prices for its chips.

Emerging Markets - Portfolio Commentary

ADDITIONAL SOURCES OF STRENGTH

We also found success in Mexico, the second-best contributor to absolute
performance, led by homebuilder Urbi Desarrollos Urbanos. The company benefited
from a favorable sales mix, with double-digit sales growth of higher-end homes,
a trend supported by the firm's partnerships with large, retail banks.

Wal-Mart de Mexico was another standout. During the period, the company
announced that it had gained market share from competitors, a development that
contributed to eight consecutive months of same-store sales growth.

Elsewhere, our investment strategy led us to Turkey's DenizBank, the portfolio's
top-contributing stock. Named one of the world's fastest-growing banks,
DenizBank recorded a 60% surge in net profit for 2004 and a 61% jump in loans
for the first half of 2005, results driven largely by increased lending to
retail customers and small- to mid-sized businesses.

INDIVIDUAL SETBACKS

Despite these successes, we nevertheless experienced some disappointments along
the way, one of which was integrated energy firm PetroKazakhstan Inc., the
portfolio's top-detracting stock. Though the company reported substantial gains
in 2004 earnings, the firm's lengthy dispute with its partner in a joint
business venture contributed to the stock's decline. We eliminated the position.

A FINAL NOTE

In August 2005, Raymond Kong departed American Century. Senior portfolio manager
Michael Donnelly, who has been a member of the Emerging Markets team since its
1997 inception, remains at the helm. The Emerging Markets team remains committed
to looking for foreign companies whose earnings and revenues are growing at an
improving rate, a strategy based on the belief that, over the long term, stock
price movements follow growth in earnings, revenues and/or cash flow.

Global Growth - Portfolio Commentary

[photo of investment team]

PORTFOLIO MANAGERS ON THE GLOBAL GROWTH INVESTMENT TEAM:
KEITH CREVELING AND HELEN O'DONNELL.

Global Growth gained 18.87%* during the 12 months ended November 30, 2005,
outperforming its benchmark, the Morgan Stanley Capital International (MSCI)
World Free Index, which returned 11.20%.

PORTFOLIO OUTPERFORMS PEERS

Global Growth also topped the average 10.59% return of the Global Large-Cap
Growth Funds tracked by Lipper Inc., finishing in the 5th percentile, or third
out 61 funds, for the fiscal year. For the three-year period, the portfolio
returned an annual 18.21% versus the 13.87% average for the Lipper category,
outperforming all but two of 53 funds to finish in the 6th percentile. For the
five-year period, Global Growth returned 1.93%, compared with the Lipper average
of negative 1.05%. outperforming all but eight of 46 funds and finishing in the
20th percentile.

MARKETS RESILIENT

During the period, many of the world's equity markets demonstrated resilience in
the face of surging prices for oil and other commodities, a terrorist attack in
London, destructive hurricanes and numerous interest-rate increases by the U.S.
Federal Reserve. In this environment, all of the sectors in which Global Growth
was invested contributed to total return. On a relative basis, Global Growth's
investments in most sectors outperformed the MSCI World Free Index, with health
care providing the most excess performance. The utilities sector detracted most
from relative performance.

FINANCIALS GAIN, OUTPERFORM

Financials contributed most to absolute return. The largest contribution from a
security in the sector came from Japan's ORIX Corp., a financial services
company, which is benefiting from Japan's improving economy and loan demand.
Prudential Financial Inc., one of the largest U.S. life insurers, topped the
list of contributors in the insurance industry. The company benefited from
strong sales of its expanded product offering in the annuity business. We also
benefited from a transaction involving Hansapank, the Baltic region's largest
lender. During the period, Sweden's Swedbank, which owned part of

Global Growth - Portfolio Commentary

Hansapank, acquired nearly all of the balance it did not already own, increasing
Hansapank's share price.

HEALTH CARE BOOSTS PORTFOLIO

Global Growth's health care companies made the second-largest contribution to
the portfolio's total return. Holdings in the biotechnology industry led the
advance, with California-based Genentech Inc. making the largest contribution to
the portfolio. Genentech, a top-10 holding, reported a number of positive
developments regarding drugs used to treat various types of cancer.

Several other holdings in the health care sector were among the period's top
contributors, including Aetna Inc., one of the largest health-insurance
providers in the U.S., and Switzerland's Roche Holding AG, the world's biggest
maker of cancer medicines and diagnostic tests. Our investments in the health
care sector also outperformed the MSCI World Free Index, making the largest
contribution to the portfolio's relative performance.

ENERGY LIFTS RETURN

Global Growth's position in the energy sector made the third-largest
contribution to the portfolio's return. Two producers of natural gas, Canada's
Encana Corp., and XTO Energy Inc. in the U.S., topped the list of contributors
as they benefited from expanded production and rising prices. Exxon Mobil Corp.
and France's Total, both top-10 positions on average, also contributed to
return.

REGARDING OUR TEAM

Global Growth is now co-managed by Keith Creveling, vice president, and Helen
O'Donnell, who has served as a senior investment analyst on Global Growth since
2000. Creveling, who continues to co-manage our International Growth strategy,
has been with American Century since 1999. Former manager Matt Hudson resigned
in November.

Despite the changes, we remain committed to looking for stocks of growing
companies in the U.S. and abroad. The investment strategy of this fund is based
on the belief that, over the long term, stock price movements follow growth in
earnings, revenue and/or cash flow.

International Opportunities - Portfolio Commentary

[photo of investment team]

PORTFOLIO MANAGERS ON THE INTERNATIONAL OPPORTUNITIES INVESTMENT TEAM:
FEDERICO LAFFAN AND TREVOR GURWICH.

International Opportunities gained 35.28%* during the 12 months ended November
30, 2005, far outdistancing its benchmark, the S&P/Citigroup EMI (Extended
Market Index) Growth World ex-US, which returned 19.21%. International
Opportunities also outpaced the 22.80% return of Foreign Small/Mid-Growth
peer group tracked by Morningstar.**

OVERSEAS MARKETS CLIMB

Many overseas equity markets advanced during the 12-month period, demonstrating
their resilience in the face of surging prices for commodities, especially oil,
a terrorist attack in London, destructive hurricanes and numerous interest-rate
increases by the U.S. Federal Reserve.

Against that backdrop, International Opportunities achieved positive absolute
contributions from each of its sector positions and outdistanced its
benchmark -- results attributable almost entirely to effective security
selection. In addition, we accomplished those gains despite the fact that the
movement of the dollar versus other currencies diminished the fund's return.

CONSUMER STOCKS PACE GAINS

The economically sensitive companies of the consumer discretionary sector, on
average our largest single stake, made the greatest contributions to both
absolute and relative performance. Our complement of household durables holdings
registered the best finish, led by Japan's Hitachi Koki, which makes power
tools.

SUCCESS IN RETAIL, REAL ESTATE

Investments among specialty retailers proved rewarding and produced one of the
portfolio's top stocks, Japan's Point Inc. Late in the year, the clothing-store
company reported double-digit growth in both same-store sales and in the number
of customers visiting its stores, news that supported the stock's climb.

International Opportunities - Portfolio Commentary

Elsewhere, we found opportunity in the real estate industry, led by Japan's
Urban Corporation. In September, the firm, which specializes in the sale and
management of condominiums, reported solid first-half earnings driven by
continued growth in the real estate market and higher lease rates for quality
properties.

We believe the strength in both companies' performance reflects the abatement of
Japan's long-standing deflation difficulty, which has in turn created a positive
environment for firms such as these by affording them greater pricing power.

INDUSTRIALS LEND STRENGTH

Our stake in the industrials sector, on average our second-largest position,
significantly augmented returns. Cosco Investment Singapore Limited, on average
the largest of the portfolio's top-ten holdings, finished as the
top-contributing stock. Cosco, a bulk carrier unit of China's largest shipping
company, continued to enjoy soaring charter rates driven by China's vibrant
economy. Cosco also benefited from increased demand for its ship-repair
services, a growing portion of its business. Both factors were catalysts behind
the earnings growth that drew our interest. Cosco repeatedly announced profits
during the period that had reached new record highs.

INDIVIDUAL SHORTFALLS

Despite overwhelmingly positive results, we nevertheless experienced some
disappointments. One was Singapore-based Accord Customer Care Solutions, a
leading provider of servicing for mobile communication and electronic devices in
the Asia-Pacific region. We owned the stock earlier in the year, and it declined
sharply following investigations of accounting irregularities. Though we
eliminated the position, it was not before incurring damage, and this was the
year's top-detracting name.

A FINAL NOTE

In February 2005, Lynette Schroeder departed American Century. Portfolio manager
Federico Laffan remains at the helm and was joined in August by portfolio
manager Trevor Gurwich, who has been with American Century since 1998.

Shareholder Fee Examples (Unaudited)

Fund shareholders may incur two types of costs: (1) transaction costs, including
sales charges (loads) on purchase payments and redemption/exchange fees; and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in your fund and to compare these costs
with the ongoing cost of investing in other mutual funds.

The example is based on an investment of $1,000 made at the beginning of the
period and held for the entire period from June 1, 2005 to November 30, 2005
(except as noted).

ACTUAL EXPENSES

The table provides information about actual account values and actual expenses
for each class. You may use the information, together with the amount you
invested, to estimate the expenses that you paid over the period. First,
identify the share class you own. Then simply divide your account value by
$1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number under the heading "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond Fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
American Century may charge you a $12.50 semiannual account maintenance fee if
the value of those shares is less than $10,000. We will redeem shares
automatically in one of your accounts to pay the $12.50 fee. In determining your
total eligible investment amount, we will include your investments in all
PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered
under your Social Security number. PERSONAL ACCOUNTS include individual
accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell
Education Savings Accounts and IRAs (including traditional, Roth, Rollover,
SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you
have only business, business retirement, employer-sponsored or American Century
Brokerage accounts, you are currently not subject to this fee. We will not
charge the fee as long as you choose to manage your accounts exclusively online.
If you are subject to the Account Maintenance Fee, your account value could be
reduced by the fee amount.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The table also provides information about hypothetical account values and
hypothetical expenses based on the actual expense ratio of each class of your
fund and an assumed rate of return of 5% per year before expenses, which is not
the actual return of a fund's share class. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in your fund and other funds. To do so, compare this
5% hypothetical example with the 5% hypothetical

                                                                    (continued)

Shareholder Fee Examples (Unaudited)

examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption/exchange fees. Therefore, the table is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

Notes to Financial Statements

NOVEMBER 30, 2005 (AMOUNTS IN THOUSANDS)

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 Stock Fund (International
Stock), International Discovery Fund (International Discovery), Emerging Markets
Fund (Emerging Markets), Global Growth Fund (Global Growth) and International
Opportunities Fund (International Opportunities) (collectively, the funds) are
five funds in a series issued by the corporation. The funds are diversified
under the 1940 Act. The funds' investment objectives are to seek capital growth.
The funds pursue their objectives by investing primarily in equity securities of
foreign companies with the exception of Global Growth, which invests in both
U.S. and foreign companies. International Stock invests in securities of issuers
in developed foreign countries that are large-sized companies. International
Discovery invests in securities of issuers in developed or emerging market
countries that are small- to medium-sized companies at the time of purchase.
Emerging Markets invests in securities of issuers in emerging market countries.
Global Growth primarily invests in securities of issuers in developed countries.
International Opportunities invests in securities of issuers in developed or
emerging market countries that are small-sized companies at the time of
purchase. The following is a summary of the funds' significant accounting
policies.

MULTIPLE CLASS -- International Stock is authorized to issue the Investor Class.
International Discovery is authorized to issue the Investor Class, the
Institutional Class and the Advisor Class. Emerging Markets is authorized to
issue the Investor Class, the Institutional Class, the Advisor Class and the C
Class. Global Growth is authorized to issue the Investor Class, the
Institutional Class, the Advisor Class, the C Class and the R Class.
International Opportunities is authorized to issue the Investor Class and the
Institutional Class. The C Class may be subject to a contingent deferred sales
charge. The share classes differ principally in their respective sales charges
and 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. Income, non-class specific expenses, and realized and unrealized
capital gains and losses of the funds are allocated to each class of shares
based on their relative net assets. Sale of International Stock's Investor Class
commenced on March 31, 2005 (fund inception). Sale of Global Growth's R Class
commenced July 29, 2005.

SECURITY VALUATIONS -- 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. Depending on
local convention or regulation, securities traded over-the-counter are valued at
the mean of the latest bid and asked prices, the last sales price, or the
official close price. Debt securities not traded on a principal securities
exchange are valued through a commercial pricing service or at the mean of the
most recent bid and asked prices. Discount notes may be valued through a
commercial pricing service or at amortized cost, which approximates fair value.
If the funds determine that the market price of a portfolio security is not
readily available, or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued at its fair value as
determined by, or in accordance with procedures adopted by, the Board of
Directors or its designee if such fair value determination would materially
impact a fund's net asset value. Circumstances that may cause the funds to fair
value a security include: an event occurred after the close of the exchange on
which a portfolio security principally trades (but before the close of the New
York Stock Exchange) that was likely to have changed the value of the security;
a security has been declared in default; or trading in a security has been
halted during the trading day.

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 securities registered in their country.
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
investment transactions 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.

SECURITIES ON LOAN -- The funds, except for International Stock, may lend
portfolio securities through their lending agent to certain approved borrowers
in order to earn additional income. The funds continue to recognize any gain or

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

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. Certain countries may impose taxes on the contract amount of
purchases and sales of foreign currency contracts in their currency. The funds
record the foreign tax expense, if any, as a reduction to the net realized gain
(loss) on foreign currency transactions.

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 funds' 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 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. Each fund requires
that the collateral, represented by securities, received in a repurchase
transaction be transferred to the custodian in a manner sufficient to enable
each fund 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 equal to or greater than amounts owed to each
fund 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 or American Century Global
Investment Management, Inc. (ACGIM), 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 each fund's policy to distribute substantially all
net investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under 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, if any, are
generally declared and paid annually. Distributions from net realized gains, if
any, are generally declared and paid twice per year.

REDEMPTION -- International Discovery, Emerging Markets and International
Opportunities may impose a 2% redemption fee on shares held less than 180 days.
International Stock and Global Growth may impose a 2% redemption fee on shares
held less than 60 days. These fees may not be applicable to all classes. These
redemption fees are recorded as a reduction in the cost of shares redeemed.
These redemption fees are retained by the funds and help cover transaction costs
that long-term investors may bear when a fund sells securities to meet investor
redemptions. Global Growth adopted the redemption fee policy effective March 1,
2004.

INDEMNIFICATIONS -- Under the corporation's organizational documents, its
officers and directors are indemnified against certain liabilities arising out
of the performance of their duties to the funds. In addition, in the normal
course of business, the funds enter into contracts that provide general
indemnifications. The funds' maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the funds.
The risk of material loss from such claims is considered by management to be
remote.

USE OF ESTIMATES -- The financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require management to make certain estimates and assumptions at the date of
the financial statements. Actual results could differ from these estimates.

                                                                   (continued)

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

MANAGEMENT FEES -- The corporation has entered into a Management Agreement with
ACGIM (the investment advisor), under which ACGIM provides the funds with
investment advisory and management services in exchange for a single, unified
management fee (the 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
ACGIM. The fee is computed and accrued daily based on the daily net assets of
each specific class of shares of each fund and paid monthly in arrears. For
funds with a stepped fee schedule, the rate of the fee is determined by applying
a fee rate calculation formula. This formula takes into account all of the
investment advisor's assets under management in each fund's investment strategy
(strategy assets) to calculate the appropriate fee rate for each fund. The
strategy assets include each fund's assets and the assets of other clients of
the investment advisor that are not in the American Century family of funds, but
that have the same investment team and investment strategy.

Effective July 29, 2005, Emerging Markets modified its management fee schedule,
resulting in lower fee rates and breakpoints. There was a reduction of the
effective annual management fee for the year ended November 30, 2005 resulting
from this change.

follows:

5. SECURITIES LENDING

As of November 30, 2005, securities in International Discovery, Emerging
Markets, Global Growth and International Opportunities valued at $239,419,
$24,711, $30,603 and $37,277, respectively, were on loan through the lending
agent, JPMCB, to certain approved borrowers. JPMCB receives and maintains
collateral in the form of cash, and/or acceptable securities as approved by ACIM
or ACGIM. Cash collateral is invested in authorized investments by the lending
agent in a pooled account. The value of cash collateral received at period end
is disclosed in the Statement of Assets and Liabilities and investments made
with the cash by the lending agent are listed in the Schedule of Investments.
Any deficiencies or excess of collateral must be delivered or transferred by the
member firms no later than the close of business on the next business day. The
total value of all collateral received, at this date, was $252,529, $25,649,
$32,196 and $39,607, respectively. The funds' risks in securities lending are
that the borrower may not provide additional collateral when required or return
the securities when due. If the borrower defaults, receipt of the collateral by
the funds may be delayed or limited.

6. BANK LINE OF CREDIT

The funds, except for International Stock, along with certain other funds
managed by ACIM or ACGIM, have a $575 million unsecured bank line of credit
agreement with JPMCB, which was renewed to $500 million effective December 14,
2005. The funds, except for International Stock, may borrow money for temporary
or emergency purposes to fund shareholder redemptions. Borrowings under the
agreement bear interest at the Federal Funds rate plus 0.50%. The funds did not
borrow from the line during the year ended November 30, 2005.

7. RISK FACTORS

There are certain risks involved in investing in foreign securities. These risks
include those resulting from future adverse political, social, and economic
developments, fluctuations in currency exchange rates, the possible imposition
of exchange controls, and other foreign laws or restrictions. Investing in
emerging markets may accentuate these risks.

                                                                    (continued)

The book-basis 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 on the financial statements. There were no
distributions paid by International Stock during the period March 31, 2005
(fund inception) through November 30, 2005.

                                                                    (continued)

NOVEMBER 30, 2005 (AMOUNTS IN THOUSANDS)

8. FEDERAL TAX INFORMATION (CONTINUED)

The difference between book-basis and tax-basis cost and unrealized appreciation
(depreciation) is attributable primarily to the tax deferral of losses on wash
sales, return of capital dividends, and on investments in passive foreign
investment companies.

The accumulated capital losses listed on the previous page represent net capital
loss carryovers that may be used to offset future realized capital gains for
federal income tax purposes. The capital loss carryovers expire as follows:

--------------------------------------------------------------------------------
                           2009         2010        2011      2012     2013

The capital and currency loss deferrals listed on the previous page represent
net capital and foreign currency losses incurred in the one-month period ended

incurred in the following fiscal year for federal income tax purposes.

(2) Total return assumes reinvestment of net investment income and capital
    gains distributions, if any. The total return of the classes may not
    precisely reflect the class expense differences because of the impact of
    calculating the net asset values to two decimal places. If net asset values
    were calculated to three decimal places, the total return differences would
    more closely reflect the class expense differences. The calculation of net
    asset values to two decimal places is made in accordance with SEC guidelines
    and does not result in any gain or loss of value between one class and
    another.

(2) Per-share amount was less than $0.005.

(3) Total return assumes reinvestment of net investment income and capital
    gains distributions, if any. The total return of the classes may not
    precisely reflect the class expense differences because of the impact of
    calculating the net asset values to two decimal places. If net asset values
    were calculated to three decimal places, the total return differences would
    more closely reflect the class expense differences. The calculation of net
    asset values to two decimal places is made in accordance with SEC guidelines
    and does not result in any gain or loss of value between one class and
    another.

Report of Independent Registered Public Accounting Firm

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

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of International Stock Fund, International
Discovery Fund, Emerging Markets Fund, Global Growth Fund and International
Opportunities Fund (collectively the "Funds"), five of the mutual funds
comprising American Century World Mutual Funds, Inc., as of November 30, 2005,
and the related statements of operations for the periods then ended, the
statements of changes in net assets for the periods presented, and the financial
highlights for the periods presented. These financial statements and financial
highlights are the responsibility of the Funds' management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Funds
are not required to have, nor were we engaged to perform, an audit of their
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Funds' internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of November 30, 2005, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds comprising American Century World Mutual Funds, Inc., as
of November 30, 2005, the results of their operations for the periods then
ended, the changes in their net assets and their financial highlights for the
periods presented, in conformity with accounting principles generally accepted
in the United States of America.

Management

The individuals listed below serve as directors or officers of the funds. Each
director serves until his or her successor is duly elected and qualified or
until he or she retires. Mandatory retirement age for independent directors is
72. Those listed as interested directors are "interested" primarily by virtue of
their engagement as officers of American Century Companies, Inc. (ACC) or its
wholly owned, direct or indirect, subsidiaries, including the funds' investment
advisor, American Century Global Investment Management, Inc. (ACGIM) or American
Century Investment Management, Inc. (ACIM); the funds' principal underwriter,
American Century Investment Services, Inc. (ACIS); and the funds' transfer
agent, American Century Services, LLC (ACS LLC).

The other directors (more than three-fourths of the total number) are
independent; that is, they have never been employees or officers of, and have no
financial interest in, ACC or any of its wholly-owned subsidiaries, including
ACGIM, ACIM, ACIS, and ACS LLC. The directors serve in this capacity for six
registered investment companies in the American Century family of funds.

All persons named as officers of the funds also serve in a similar capacity for
the other 13 investment companies advised by ACIM or ACGIM, unless otherwise
noted. Only officers with policy-making functions are listed. No officer is
compensated for his or her service as an officer of the funds. The listed
officers are interested persons of the funds and are appointed or re-appointed
on an annual basis. The information below is provided as of December 15, 2005.

Approval of Management Agreements for International Discovery, Emerging Markets,
Global Growth and International Opportunities

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors (the "Directors") each year. At
American Century, this process -- referred to as the "15(c) Process" -- involves
at least two board meetings spanning a 30 to 60 day period each year. In
addition to this annual review, the board of directors and its committees
oversee and evaluate at quarterly meetings the nature and quality of significant
services the advisor performs on behalf of the fund. At these meetings the board
reviews fund performance, shareholder services and feedback, audit and
compliance information, and a variety of other reports from the advisor
concerning fund operations. The board, or committees of the board, also hold
special meetings, as needed.

Under a new Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for its board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year, the Directors requested and received extensive data and information
compiled by the advisor and certain independent providers of evaluative data
(the "Independent 15(c) Providers") concerning International Discovery, Emerging
Markets, Global Growth and International Opportunities (collectively, the
"funds") and the services provided to the funds under the management agreement.
The information included, but was not limited to:

*    the nature, extent and quality of investment management, shareholder
     services and other services provided to the funds under the management
     agreement;

*    reports on the advisor's activities relating to the wide range of
     programs and services the advisor provides to the funds and its
     shareholders on a routine and non-routine basis;

*    data comparing the cost of owning the funds to the cost of owning
     similar funds;

*    data comparing the funds' performance to appropriate benchmarks
     and/or a peer group of other mutual funds with similar investment
     objectives and strategies;

*    financial data showing the profitability of the funds to the advisor
     and the overall profitability of the advisor; and

*    data comparing services provided and charges to other investment
     management clients of the advisor.

In keeping with its practice, the funds' board of directors held two regularly
scheduled meetings and two special meetings to review and discuss the
information provided by the advisor and the Independent 15(c) Providers and to
complete its negotiations with the advisor regarding the renewal of the
management agreement, including the setting of the applicable advisory fee. In
addition, the independent directors met

                                                                    (continued)

Approval of Management Agreements for International Discovery, Emerging Markets,

on several occasions in private session to review and discuss the information
provided and evaluate the advisor's performance as manager of the funds.

FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor, the
Independent 15(c) Providers, and its independent counsel and evaluated such
information for each fund for which the board has responsibility. The Directors
did not identify any single factor as being all-important or controlling, and
each Director may have attributed different levels of importance to different
factors. In deciding to renew the agreement under the terms ultimately
determined by the board to be appropriate, the Directors' decision was based on
the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the funds. The board noted that under
the management agreement, the advisor provides or arranges at its own expense a
wide variety of services including, but not limited to:

*    fund construction and design

*    portfolio security selection

*    initial capitalization/funding

*    securities trading

*    custody of fund assets

*    daily valuation of the funds' portfolios

*    shareholder servicing and transfer agency, including shareholder
     confirmations, recordkeeping and communications

*    legal services

*    regulatory and portfolio compliance

*    financial reporting

*    marketing and distribution

The Directors noted that many of these services have expanded over time both in
terms of quantity and complexity in response to shareholder demands, competition
in the industry and the changing regulatory environment. In performing their
evaluation, the Directors considered information received in connection with the
annual review, as well as information provided on an ongoing basis at their
regularly scheduled board and committee meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services
provided is quite complex and allows fund shareholders access to professional
money management, instant diversification of their investments within an asset
class, the opportunity to easily diversify among asset classes, and liquidity.
In evaluating investment performance, the board expects the advisor to manage
the funds in accordance with its investment objective and approved strategies.
In providing these services, the advisor utilizes teams of investment
professionals (portfolio managers, analysts, research assistants, and securities
traders) who require extensive information technology, research, training,
compliance and other systems to conduct their business. At each quarterly
meeting the Directors review investment performance information for the funds,
together with comparative information for appropriate benchmarks and a peer
group of funds

                                                                    (continued)

managed similarly to the funds. If performance concerns are identified, the
Directors discuss with the advisor and its portfolio managers the reasons for
such results (e.g., market conditions, security selection) and any efforts being
undertaken to improve performance. Annually, the Directors review detailed
performance information, as provided by the Independent 15(c) Providers,
comparing the funds' performance with that of similar funds not managed by the
advisor. Global Growth's performance was above the median of its peer group for
both one and three year periods during part of the past year. International
Opportunities' performance was at the median of its peer group for the one year
period and above the median for the three year period. International Discovery's
performance fell below the median of its peer groups for both one and three year
periods during the past year. Emerging Market's performance fell below the
median of its peer groups for both one and three year periods during part of the
past year. The Directors discussed the funds' performance with the advisor and
were satisfied with the efforts being undertaken by the advisor. The Directors
will continue to monitor those efforts and the performance of the funds.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at its regular
quarterly meetings, including the annual meeting concerning contract review.
These reports include, but are not limited to, information regarding the
operational efficiency and accuracy of the shareholder and transfer agency
services provided, staffing levels, shareholder satisfaction (as measured by
external as well as internal sources), technology support, new products and
services offered to fund shareholders, securities trading activities, portfolio
valuation services, auditing services, and legal and operational compliance
activities. Certain aspects of shareholder and transfer agency service level
efficiency and the quality of securities trading activities are measured by
independent third party providers and are presented in comparison to other fund
groups not managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various services
to the funds, its profitability in managing the funds, its overall
profitability, and its financial condition. The Directors have reviewed with the
advisor the methodology used to prepare this financial information. This
financial information regarding the advisor is considered in order to evaluate
the advisor's financial condition, its ability to continue to provide services
under the management agreement, and the reasonableness of the current management
fee.

ETHICS OF THE ADVISOR. The Directors generally considered the advisor's
commitment to providing quality services to shareholders and to conducting its
business ethically. They noted that the advisor's practices generally meet or
exceed industry best practices and that

                                                                    (continued)

the advisor was not implicated in the industry scandals of 2003 and 2004.

ECONOMIES OF SCALE. The Directors review reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes in
revenue, costs, and profitability. The Directors concluded that economies of
scale are difficult to measure with precision, particularly on a fund-by-fund
basis. This analysis is further complicated by the fact that the advisor is
required to make a continuing reinvestment in the business to provide additional
content and services for fund shareholders. Accordingly, the Directors also seek
to evaluate economies of scale by reviewing other information, such as
year-over-year profitability of the advisor generally, the profitability of its
management of the funds specifically, the expenses incurred by the advisor in
providing various services to the funds, and the breakpoint fees of competitive
funds not managed by the advisor. The Directors believe the advisor is
appropriately sharing any economies of scale through a competitive fee
structure, through breakpoints that reduce fees as the fund increases in size,
and through reinvestment in its business to provide shareholders additional
content and services.

COMPARISON TO OTHER FUNDS' FEES. The funds pay the advisor a single,
all-inclusive (or unified) management fee for providing all services necessary
for the management and operation of the funds, other than brokerage expenses,
taxes, interest, extraordinary expenses, and the fees and expenses of the funds'
independent directors (including their independent legal counsel). Under the
unified fee structure, the advisor is responsible for providing all investment
advisory, custody, audit, administrative, compliance, recordkeeping, marketing
and shareholder services, or arranging and supervising third parties to provide
such services. By contrast, most other fund groups are charged a variety of
fees, including an investment advisory fee, a transfer agency fee, an
administrative fee, distribution charges and other expenses. Other than their
investment advisory fees and Rule 12b-1 distribution fees, all other components
of the total fees charged by these other fund groups may be increased without
shareholder approval. The board believes the unified fee structure is a benefit
to fund shareholders because it clearly discloses to shareholders the cost of
owning fund shares, and, since the unified fee cannot be increased without a
vote of fund shareholders, it shifts to the advisor the increased costs of
operating the funds and the risk of administrative inefficiencies. Part of the
Directors' analysis of fee levels involves comparing the funds' unified fee to
the total expense ratio of other funds in the funds' peer group. The unified fee
charged to International Discovery's shareholders was below the median of the
total expense ratios of its peer group. The unified fees charged to Emerging
Market's and International Opportunities' shareholders were above the median of
the total expense ratios of its peer group. The unified fee charged Global
Growth's shareholders was at the median of the total expense ratios of its peer
group.

                                                                    (continued)

Global Growth and International Opportunities

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services to
advisory clients other than the funds. They observed that these varying types of
client accounts require different services and involve different regulatory and
entrepreneurial risks than the management of the funds. The Directors analyzed
this information and concluded that the fees charged and services provided to
the funds were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the funds. They concluded that the advisor's primary business
is managing mutual funds and it generally does not use fund or shareholder
information to generate profits in other lines of business, and therefore does
not derive any significant collateral benefits from them. The Directors noted
that the advisor receives proprietary research from broker dealers that execute
fund portfolio transactions and concluded that this research is likely to
benefit fund shareholders. The Directors also determined that the advisor is
able to provide investment management services to clients other than the funds,
at least in part, due to its existing infrastructure built to serve the fund
complex. The Directors concluded, however, that the assets of those other
clients are not material to the analysis and in any event are added to the
assets of the funds within the fund complex that use substantially the same
investment management team to determine whether each fund has reached
breakpoints in its fee schedule.

CONCLUSIONS OF THE DIRECTORS

As a result of this process, the Directors, assisted by the advice of legal
counsel that is independent of the advisor, taking into account all of the
factors discussed above and the information provided by the advisor and the
Independent 15(c) Providers concluded (i) that the investment management
agreement between International Discovery, Global Growth and International
Opportunities and the advisor is fair and reasonable in light of the services
provided and should be renewed and (ii) negotiated changes to the breakpoint
schedule used to calculate the management fee of Emerging Markets. These changes
were proposed by the Directors based on their review of the competitive changes
in the mutual fund marketplace and their review of financial information
provided by the advisor. The new schedule, effective July 29, 2005, will
accelerate management fee reductions at lower asset levels than under the
existing structure. Following these negotiations with the advisor, the Directors
concluded that the investment management agreement between Emerging Markets and
the advisor, amended as described above, is fair and reasonable in light of the
services provided and should be renewed.

Additional Information

RETIREMENT ACCOUNT INFORMATION

As required by law, any distributions you receive from an IRA or certain 403(b),
457 and qualified plans [those not eligible for rollover to an IRA or to another
qualified plan] are subject to federal income tax withholding, unless you elect
not to have withholding apply. Tax will be withheld on the total amount
withdrawn even though you may be receiving amounts that are not subject to
withholding, such as nondeductible contributions. In such case, excess amounts
of withholding could occur. You may adjust your withholding election so that a
greater or lesser amount will be withheld.

If you don't want us to withhold on this amount, you must notify us to not
withhold the federal income tax. 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 notice not to withhold federal
income tax prior to the withdrawal. You may notify us in writing or in certain
situations by telephone or through other electronic means. You have the right to
revoke your withholding election at any time and any election you make may
remain in effect until revoked by filing a new election.

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.

State tax will be withheld if, at the time of your distribution, your address is
within one of the mandatory withholding states and you have federal income tax
withheld. State taxes will be withheld from your distribution in accordance with
the respective state rules.

Life Sciences - Portfolio Commentary

PORTFOLIO MANAGERS ON THE LIFE SCIENCES INVESTMENT TEAM: ARNOLD DOUVILLE AND
CHRISTY TURNER.

Life Sciences gained 13.43%* during the 12 months ended November 30, 2005,
outperforming the 10.26% return of the S&P Composite 1500 Health Care Index (the
Composite). Since its June 30, 2000, inception, the fund has achieved an average
annual return of 1.63%, ahead of the 0.12% return posted by the Composite.

STOCKS OVERCOME CHALLENGES

Equity investors faced numerous challenges during the months covered by this
report, a period that saw eight increases in short-term interest rates, a new
record high for oil, and three major hurricanes. Despite those challenges, the
equities market ultimately demonstrated resilience and secured solid gains.

Against that backdrop, Life Sciences achieved positive contributions from all
but one of its industry selections in the health care sector. The fund delivered
performance that surpassed that of the Composite, results attributable to
effective stock selection.

HEALTH CARE PROVIDERS PACE GAINS

Health care providers and services companies commanded considerable attention
during the fiscal year, and the group emerged as a clear market leader,
evidenced by the 23.03% gain of the Morgan Stanley Healthcare Providers Index,
which tracks the performance of hospitals, and the 45.05% advance of the Morgan
Stanley Healthcare Payor Index, which measures the progress of HMOs.

This group represented, on average, our largest single stake. The majority of
our holdings fared well, including PacifiCare Health Systems, UnitedHealth Group
Inc., Aetna Inc., and Renal Care Group Inc., all of which ranked high among the
contributors.

The most rewarding position in this area was WellPoint, an HMO and our
top-contributing stock. During the period, WellPoint continued to benefit from
the successful completion of its merger with Anthem, a deal valued at $16.5
billion, and announced plans to merge with WellChoice. The company also
consistently reported improved

Life Sciences - Portfolio Commentary

revenues driven by solid pricing, increased membership and cost controls. All
were factors that supported the stock's climb.

SUCCESS IN BIOTECHNOLOGY

Biotechnology stocks also garnered investors' attentions, as reflected in the
29.84% climb of the AMEX Biotechnology Index during the year. We focused on
large, established companies --a strategy that made this group a rich source of
absolute performance and produced a top-contributing stock that was not
represented in the Composite. Genentech, a leading biotech firm, benefited from
the results of clinical trials that underscored the effectiveness of its drugs
Avastin and Herceptin in improving survival for cancer patients, news that was
well received by investors.

SOME DISAPPOINTMENTS

While investments in the health care equipment and supplies industry augmented
returns overall, some holdings nonetheless fell short. One was
orthopedic-products firm Biomet, which makes replacement joints. Though the
company twice reported record earnings, its stock faltered early in the period
amid scrutiny into consultant and service agreements and payment practices by
numerous firms in the industry, including Biomet. Still, we view this issue as
transitory and see increased demand for its stable of products. Because of our
continued confidence in this firm's long-term growth prospects, we have
maintained a position.

Elsewhere, our stake in the pharmaceutical industry, the only industry-level
detractor in the health care sector, represented a modest drag on absolute
performance. Several of our holdings retreated, including Pfizer, among the
portfolio's top detractors. Late in the year, Pfizer reported that patent
expirations and increased generic competition alongside slower prescription
rates had eroded revenues. The share price fell sharply, and though we
eliminated the position, it was not before incurring a loss.

Overall, however, we remained underweight the pharmaceutical stocks, and better
security selection helped us avoid some of the market's most downtrodden names
in favor of those that either advanced or suffered lesser declines.
Consequently, this industry represented our greatest source of strength relative
to the Composite.

Technology - Portfolio Commentary

PORTFOLIO MANAGER ON THE TECHNOLOGY INVESTMENT TEAM: TOM TELFORD.

Technology gained 7.75%* during the 12 months ended November 30, 2005,
outperforming its benchmark, the S&P Composite 1500 Technology Index (the
Composite), which rose only 7.21%.

SECOND-HALF SURGE

It was a tale of two markets as stocks, technology stocks in particular,
struggled in the first half of the fiscal year. After bottoming out in April,
however, stocks rebounded with tech stocks leading the way. For instance, the
Composite declined 1.39% for the first six months covered by this report, then
gained 8.72% in the final half of the period.

THE INTERNET REVOLUTION

Technology's strongest performance came from the Internet software and services
industry. The portfolio's holdings here in aggregate gained approximately 56%,
far outpacing the benchmark's 9% return in this sector. Internet search-engine
company Google was responsible for much of the portfolio's advance, spurred by
strong earnings reports.

Google is at the forefront of the move toward online advertising. Consumers are
spending more of their media time online, and advertising dollars are following.
Technology research firm Forrester Research predicted total U.S. online
advertising and marketing spending in 2005 of nearly $15 billion, a 23% increase
over 2004. It expects that amount to almost double by 2010. The global expansion
of the Internet and online advertising has helped propel other companies in the
portfolio, including Tokyo-based Softbank, which owns a 42% stake in Yahoo
Japan.

APPLE'S HALO EFFECT

Apple Computer was another leading contributor in the portfolio as the success
of the iPod and market-share gains in personal computers boosted revenues and
earnings. Apple uses flash memory in its iPod products instead of hard-disk
drives for storage, which helped lift the stocks of flash memory companies.

The growing demand for flash technology in consumer electronics fueled

Technology - Portfolio Commentary

a surge in SanDisk's stock. The flash-memory maker owns a large portion of the
intellectual property rights surrounding flash technology. This means that in
addition to the profits it earns on its own products, SanDisk also receives
royalty payments from other companies, which boosts revenues and earnings as
flash becomes more widely used.

SETBACKS

Data-integration software maker TIBCO Software was the top individual detractor
to Technology's returns. TIBCO's share price fell sharply in early March when
the company unexpectedly lowered its earnings target due to sales missteps in
Europe. Shares in QLogic, a maker of storage networking components, slid on
worries about slowing growth in the storage network business. Both positions
were sold.

SELECTIVE MARKET

The technology sector has been a challenging place to invest in the past five
years. However, we are encouraged by a variety of data that suggest we are
entering a period that may favor select technology shares.

The economy has been growing at a moderate, healthy rate, and corporate earnings
have posted solid double-digit gains for the past 12 straight quarters. In fact,
corporations have been sitting on record levels of cash and are now finding that
they need to invest in technology again in order to maintain earnings and
productivity growth.

For instance, we see growing interest in the convergence of wireless
networking--combining voice, video and data capabilities into a single device
without disruption in connections. Motorola, a top-ten position, calls this
"seamless mobility," and it's taking a lead role in developing next-generation
networks, services and devices. The stock was a top contributor during the
fund's fiscal year, bolstered in part by the popularity of its new Razr
cellphone.

We remain committed to pursuing attractive investment opportunities for the
portfolio. In the months ahead, we will continue searching for companies
benefiting from positive developments in the technology sector.

Shareholder Fee Examples

(Unaudited)

Fund shareholders may incur two types of costs: (1) transaction costs, including
sales charges (loads) on purchase payments and redemption/exchange fees; and (2)
ongoing costs, including management fees; distribution and service (12b-1) fees;
and other fund expenses. This example is intended to help you understand your
ongoing costs (in dollars) of investing in your fund and to compare these costs
with the ongoing cost of investing in other mutual funds.

The example is based on an investment of $1,000 made at the beginning of the
period and held for the entire period from June 1, 2005 to November 30, 2005.

ACTUAL EXPENSES

The table provides information about actual account values and actual expenses
for each class. You may use the information, together with the amount you
invested, to estimate the expenses that you paid over the period. First,
identify the share class you own. Then simply divide your account value by
$1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then
multiply the result by the number under the heading "Expenses Paid During
Period" to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century fund, or Institutional
Class shares of the American Century Diversified Bond Fund, in an American
Century account (i.e., not a financial intermediary or retirement plan account),
American Century may charge you a $12.50 semiannual account maintenance fee if
the value of those shares is less than $10,000. We will redeem shares
automatically in one of your accounts to pay the $12.50 fee. In determining your
total eligible investment amount, we will include your investments in all
PERSONAL ACCOUNTS (including American Century Brokerage accounts) registered
under your Social Security number. PERSONAL ACCOUNTS include individual
accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell
Education Savings Accounts and IRAs (including traditional, Roth, Rollover,
SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you
have only business, business retirement, employer-sponsored or American Century
Brokerage accounts, you are currently not subject to this fee. We will not
charge the fee as long as you choose to manage your accounts exclusively online.
If you are subject to the Account Maintenance Fee, your account value could be
reduced by the fee amount.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The table also provides information about hypothetical account values and
hypothetical expenses based on the actual expense ratio of each class of your
fund and an assumed rate of return of 5% per year before expenses, which is not
the actual return of a fund's share class. The hypothetical account values and
expenses may not be used to estimate the actual ending account balance or
expenses you paid for the period. You may use this information to compare the
ongoing costs of investing in your fund and other funds. To do so, compare this
5% hypothetical example with the 5% hypothetical examples that appear in the
shareholder reports of the other funds.

                                                                  (continued)

Shareholder Fee Examples (Unaudited)

Please note that the expenses shown in the table are meant to highlight your
ongoing costs only and do not reflect any transactional costs, such as sales
charges (loads) or redemption/exchange fees. Therefore, the table is useful in
comparing ongoing costs only, and will not help you determine the relative total
costs of owning different funds. In addition, if these transactional costs were
included, your costs would have been higher.

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. Life Sciences Fund (Life Sciences) and
Technology Fund (Technology) (collectively, the funds) are two funds in a series
issued by the corporation. The funds are nondiversified under the 1940 Act. The
funds' investment objectives are to seek capital growth. Life Sciences and
Technology pursue their objectives by investing primarily in stocks of growing
companies in the life sciences and in the technology and
telecommunications-related sectors, respectively. Life Sciences invests at least
80% of its assets in companies that engage in the business of providing products
and services that help promote health and wellness. Technology invests at least
80% of its assets in companies primarily engaged in offering, using or
developing products, processes or services that provide or will benefit
significantly from technological advancements or improvements. The following is
a summary of the funds' significant accounting policies.

MULTIPLE CLASS -- Life Sciences is authorized to issue the Investor Class, the
Institutional Class, the Advisor Class and the C Class. Technology is authorized
to issue the Investor Class, the Institutional Class and the Advisor Class. The
C Class may be subject to a contingent deferred sales charge. The share classes
differ principally in their respective sales charges and shareholder servicing
and distribution expenses and arrangements. All shares of each fund represent an
equal pro rata interest in the 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. Income, non-class specific
expenses, and realized and unrealized capital gains and losses of the funds are
allocated to each class of shares based on their relative net assets.

SECURITY VALUATIONS -- 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. Depending on
local convention or regulation, securities traded over-the-counter are valued at
the mean of the latest bid and asked prices, the last sales price, or the
official close price. Debt securities not traded on a principal securities
exchange are valued through a commercial pricing service or at the mean of the
most recent bid and asked prices. Discount notes may be valued through a
commercial pricing service or at amortized cost, which approximates fair value.
If the funds determine that the market price of a portfolio security is not
readily available, or that the valuation methods mentioned above do not reflect
the security's fair value, such security is valued at its fair value as
determined by, or in accordance with procedures adopted by, the Board of
Directors or its designee if such fair value determination would materially
impact a fund's net asset value. Circumstances that may cause the funds to fair
value a security include: an event occurred after the close of the exchange on
which a portfolio security principally trades (but before the close of the New
York Stock Exchange) that was likely to have changed the value of the security;
a security has been declared in default; or trading in a security has been
halted during the trading day.

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

INVESTMENT INCOME -- Dividend income less foreign taxes withheld, if any, is
recorded as of the ex-dividend date. Distributions received on securities that
represent a return of capital or capital gain are recorded as a reduction of
cost of investments and/or as a realized gain. The funds estimate the components
of distributions received that may be considered nontaxable distributions or
capital gain distributions for income tax purposes. Interest income is recorded
on the accrual basis and includes accretion of discounts and amortization of
premiums.

SECURITIES ON LOAN -- The funds may lend portfolio securities through their
lending agent to certain approved borrowers in order to earn additional income.
The funds continue to recognize any gain or loss in the market price of the
securities loaned and record any interest earned or dividends declared.

EXCHANGE TRADED FUNDS -- The funds may invest in exchange traded funds (ETFs).
ETFs are a type of index fund bought and sold on a securities exchange. An ETF
trades like common stock and represents a fixed portfolio of securities designed
to track the performance and dividend yield of a particular domestic or foreign
market index. A fund may purchase an ETF to temporarily gain exposure to a
portion of the U.S. or a foreign market while awaiting purchase of underlying
securities. The risks of owning an ETF generally reflect the risks of owning the
underlying securities they are designed to track, although the lack of liquidity
on an ETF could result in it being more volatile. Additionally, ETFs have
management fees, which increase their cost.

                                                                    (continued)

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

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. For assets and
liabilities, other than investments in securities, net 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 investment transactions and unrealized appreciation
(depreciation) on investments, respectively. Certain countries may impose taxes
on the contract amount of purchases and sales of foreign currency contracts in
their currency. The funds record the foreign tax expense, if any, as a reduction
to the net realized gain (loss) on foreign currency transactions.

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 funds' 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 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. Each fund requires
that the collateral, represented by securities, received in a repurchase
transaction be transferred to the custodian in a manner sufficient to enable
each fund 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 equal to or greater than amounts owed to each
fund 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 or American Century Global
Investment Management, Inc. (ACGIM), 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 each fund's policy to distribute substantially all
net investment income and net realized gains to shareholders and to otherwise
qualify as a regulated investment company under 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, if any, are
generally declared and paid annually. Distributions from net realized gains, if
any, are generally declared and paid twice per year.

INDEMNIFICATIONS -- Under the corporation's organizational documents, its
officers and directors are indemnified against certain liabilities arising out
of the performance of their duties to the funds. In addition, in the normal
course of business, the funds enter into contracts that provide general
indemnifications. The funds' maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the funds.
The risk of material loss from such claims is considered by management to be
remote.

USE OF ESTIMATES -- The financial statements are prepared in conformity with
accounting principles generally accepted in the United States of America, which
may require management to make certain estimates and assumptions at the date of
the financial statements. Actual results could differ from these estimates.

                                                                     (continued)

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

MANAGEMENT FEES - The corporation has entered into a Management Agreement with
ACIM for Technology and ACGIM for Life Sciences (the investment advisor,
respectively), under which the investment advisor provides the funds with
investment advisory and management services in exchange for a single, unified
management fee (the 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
the investment advisor. The fee is computed and accrued daily based on the daily
net assets of each specific class of shares of each fund and paid monthly in
arrears. For funds with a stepped fee schedule, the rate of the fee is
determined by applying a fee rate calculation formula. This formula takes into
account all of the investment advisor's assets under management in each fund's
investment strategy (strategy assets) to calculate the appropriate fee rate for
each fund. The strategy assets include each fund's assets and the assets of
other clients of the investment advisor that are not in the American Century
family of funds, but that have the same investment team and investment strategy.

The annual management fee schedule for each class of the funds, as applicable is
as follows:

-----------------------------------------------------------------------------
                      INVESTOR & C       INSTITUTIONAL         ADVISOR
-----------------------------------------------------------------------------
STRATEGY ASSETS
-----------------------------------------------------------------------------
First $250 million       1.50%               1.30%              1.25%
-----------------------------------------------------------------------------
Next $250 million        1.40%               1.20%              1.15%
-----------------------------------------------------------------------------
Next $250 million        1.30%               1.10%              1.05%
-----------------------------------------------------------------------------
Over $750 millon         1.20%               1.00%              0.95%
-----------------------------------------------------------------------------

The effective annual management fee for each class of the funds for the year
ended November 30, 2005 was 1.50%, 1.30%, 1.25% and 1.50% for the Investor
Class, Institutional Class, Advisor Class and C Class, respectively, as
applicable.

ACGIM has entered into a Subadvisory Agreement with ACIM (the investment
subadvisor) on behalf of Life Sciences. The subadvisor makes investment
decisions for the cash portion of Life Sciences in accordance with Life
Sciences' investment objectives, policies and restrictions under the supervision
of ACGIM and the Board of Directors. ACGIM pays all costs associated with
retaining ACIM as the subadvisor of Life Sciences.

DISTRIBUTION AND SERVICE FEES -- The Board of Directors has adopted a Master
Distribution and Shareholder Services Plan for the Advisor Class and a Master
Distribution and Individual Shareholder Services Plan for the C Class
(collectively, the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans
provide that the Advisor Class and C Class will pay American Century Investment
Services, Inc. (ACIS) the following annual distribution and service fees:
--------------------------------------------------------------------------------
                                         ADVISOR                       C
--------------------------------------------------------------------------------
Distribution Fee                          0.25%                      0.75%
--------------------------------------------------------------------------------
Service Fee                               0.25%                      0.25%
--------------------------------------------------------------------------------

The fees are computed and accrued daily based on each class's daily net assets
and paid monthly in arrears. The distribution fee provides compensation for
expenses incurred by financial intermediaries in connection with distributing
shares of the classes 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 ACIS, its affiliates or
independent third party providers for Advisor Class shares and for individual
shareholder services rendered by broker/dealers or other independent financial
intermediaries for C Class shares. Fees incurred under the plans during the year
ended November 30, 2005, are detailed in the Statement of Operations.

RELATED PARTIES -- Certain officers and directors of the corporation are also
officers and/or directors, and, as a group, controlling stockholders of American
Century Companies, Inc. (ACC), the parent of the corporation's investment
advisor, ACIM or ACGIM, the distributor of the corporation, ACIS, and the
corporation's transfer agent, American Century Services, LLC.

The funds have a bank line of credit agreement and securities lending agreement
with JPMorgan Chase Bank (JPMCB). JPMCB is a custodian of the funds and a wholly
owned subsidiary of J.P. Morgan Chase & Co. (JPM). JPM is an equity investor in
ACC.

                                                                      (continued

5. SECURITIES LENDING

As of November 30, 2005, securities in Life Sciences and Technology valued at
$19,720,156 and $26,099,192, respectively, were on loan through the lending
agent, JPMCB, to certain approved borrowers. JPMCB receives and maintains
collateral in the form of cash, and/or acceptable securities as approved by ACIM
or ACGIM. Cash collateral is invested in authorized investments by the lending
agent in a pooled account. The value of cash collateral received at period end
is disclosed in the Statement of Assets and Liabilities and investments made
with the cash by the lending agent are listed in the Schedule of Investments.
Any deficiencies or excess of collateral must be delivered or transferred by the
member firms no later than the close of business on the next business day. The
total value of all collateral received, at this date, was $19,860,495 and
$26,260,223, respectively. The funds' risks in securities lending are that the
borrower may not provide additional collateral when required or return the
securities when due. If the borrower defaults, receipt of the collateral by the
funds may be delayed or limited.

6. BANK LINE OF CREDIT

The funds, along with certain other funds managed by ACIM or ACGIM, have a
$575,000,000 unsecured bank line of credit agreement with JPMCB, which was
renewed to $500,000,000 effective December 14, 2005. The funds may borrow money
for temporary or emergency purposes to fund shareholder redemptions. Borrowings
under the agreement bear interest at the Federal Funds rate plus 0.50%. The
funds did not borrow from the line during the year ended November 30, 2005.

                                                                   (continued)

Notes to Financial Statements

NOVEMBER 30, 2005

7. RISK FACTORS

The funds concentrate their investments in a narrow segment of the total market.
Because of this, the funds may be subject to greater risks and market
fluctuations than a portfolio representing a broader range of industries.

8. FEDERAL TAX INFORMATION

The book-basis 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 on the financial statements. There were no
distributions paid by the funds during the years ended November 30, 2005 and
November 30, 2004.

As of November 30, 2005, the components of distributable earnings on a tax-basis
and the federal tax cost of investments were as follows:

                                                  LIFE SCIENCES    TECHNOLOGY
--------------------------------------------------------------------------------
Federal tax cost of investments                    $163,285,625    $148,180,526

Currency loss deferral                                       --         $(9,649)
--------------------------------------------------------------------------------

The difference between book-basis and tax-basis cost and unrealized appreciation
(depreciation) is attributable primarily to the tax deferral of losses on wash
sales, the realization for tax purposes of unrealized gains on certain forward
foreign currency contracts, and return of capital dividends recieved.

The accumulated capital losses listed above represent net capital loss
carryovers that may be used to offset future realized capital gains for federal
income tax purposes. The capital loss carryovers expire as follows:

                             2009                  2010
-------------------------------------------------------------
Life Sciences                 --               $21,395,404
-------------------------------------------------------------
Technology               $182,228,391          $52,734,830
-------------------------------------------------------------

The capital and currency loss deferrals represent net foreign currency losses
incurred in the one-month period ended November 30, 2005. The funds have elected
to treat such losses as having been incurred in the following fiscal year for
federal income tax purposes.

Report of Independent Registered
Public Accounting Firm

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

We have audited the accompanying statements of assets and liabilities, including
the schedules of investments, of Life Sciences Fund and Technology Fund
(collectively the "Funds"), two of the mutual funds comprising American Century
World Mutual Funds, Inc., as of November 30, 2005, and the related statements of
operations for the year then ended, the statements of changes in net assets for
each of the two years in the period then ended, and the financial highlights for
the periods presented. These financial statements and financial highlights are
the responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. The Funds
are not required to have, nor were we engaged to perform, an audit of their
internal control over financial reporting. Our audits included consideration of
internal control over financial reporting as a basis for designing audit
procedures that are appropriate in the circumstances, but not for the purpose of
expressing an opinion on the effectiveness of the Funds' internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. Our procedures included confirmation
of securities owned as of November 30, 2005, by correspondence with the
custodian and brokers; where replies were not received from brokers, we
performed other auditing procedures. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Life
Sciences Fund and Technology Fund, as of November 30, 2005, the results of their
operations for the year then ended, the changes in their net assets for each of
the two years for the period then ended and their financial highlights for the
periods presented, in conformity with accounting principles generally accepted
in the United States of America.

Management

The individuals listed below serve as directors or officers of the funds. Each
director serves until his or her successor is duly elected and qualified or
until he or she retires. Mandatory retirement age for independent directors is
72. Those listed as interested directors are "interested" primarily by virtue of
their engagement as officers of American Century Companies, Inc. (ACC) or its
wholly owned, direct or indirect, subsidiaries, including the funds' investment
advisor, American Century Global Investment Management, Inc. (ACGIM) or American
Century Investment Management, Inc. (ACIM); the funds' principal underwriter,
American Century Investment Services, Inc. (ACIS); and the funds' transfer
agent, American Century Services, LLC (ACS LLC).

The other directors (more than three-fourths of the total number) are
independent; that is, they have never been employees or officers of, and have no
financial interest in, ACC or any of its wholly-owned subsidiaries, including
ACGIM, ACIM, ACIS, and ACS LLC. The directors serve in this capacity for six
registered investment companies in the American Century family of funds.

All persons named as officers of the funds also serve in a similar capacity for
the other 13 investment companies advised by ACIM or ACGIM, unless otherwise
noted. Only officers with policy-making functions are listed. No officer is
compensated for his or her service as an officer of the funds. The listed
officers are interested persons of the funds and are appointed or re-appointed
on an annual basis. The information below is provided as of December 15, 2005.

Approval of Management Agreements for Life Sciences and Technology

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors (the "Directors") each year. At
American Century, this process -- referred to as the "15(c) Process" -- involves
at least two board meetings spanning a 30 to 60 day period each year. In
addition to this annual review, the board of directors and its committees
oversee and evaluate at quarterly meetings the nature and quality of significant
services the advisor performs on behalf of the fund. At these meetings the board
reviews fund performance, shareholder services and feedback, audit and
compliance information, and a variety of other reports from the advisor
concerning fund operations. The board, or committees of the board, also hold
special meetings, as needed.

Under a new Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for its board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year, the Directors requested and received extensive data and information
compiled by the advisor and certain independent providers of evaluative data
(the "Independent 15(c) Providers") concerning Life Sciences and Technology
(collectively, the "funds") and the services provided to the funds under the
management agreement. The information included, but was not limited to:

*    the nature, extent and quality of investment management, shareholder
     services and other services provided to the funds under the management
     agreement;

*    reports on the advisor's activities relating to the wide range of
     programs and services the advisor provides to the funds and its
     shareholders on a routine and non-routine basis;

*    data comparing the cost of owning the funds to the cost of owning
     similar funds;

*    data comparing the funds' performance to appropriate benchmarks
     and/or a peer group of other mutual funds with similar investment
     objectives and strategies;

*    financial data showing the profitability of the funds to the advisor
     and the overall profitability of the advisor; and

*    data comparing services provided and charges to other investment
     management clients of the advisor.

In keeping with its practice, the funds' board of directors held two regularly
scheduled meetings and two special meetings to review and discuss the
information provided by the advisor and the Independent 15(c) Providers and to
complete its negotiations with the advisor regarding the renewal of the
management agreement, including the setting of the applicable advisory fee. In
addition, the independent directors met on several occasions in private session
to review and discuss the information provided and evaluate the advisor's
performance as manager of the funds.

                                                                    (continued)

Approval of Management Agreements for Life Sciences and Technology

FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor, the
Independent 15(c) Providers, and its independent counsel and evaluated such
information for each fund for which the board has responsibility. The Directors
did not identify any single factor as being all-important or controlling, and
each Director may have attributed different levels of importance to different
factors. In deciding to renew the agreement under the terms ultimately
determined by the board to be appropriate, the Directors' decision was based on
the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the funds. The board noted that under
the management agreement, the advisor provides or arranges at its own expense a
wide variety of services including, but not limited to:

*    fund construction and design

*    portfolio security selection

*    initial capitalization/funding

*    securities trading

*    custody of fund assets

*    daily valuation of the funds' portfolios

*    shareholder servicing and transfer agency, including shareholder
     confirmations, recordkeeping and communications

*    legal services

*    regulatory and portfolio compliance

*    financial reporting

*    marketing and distribution

The Directors noted that many of these services have expanded over time both in
terms of quantity and complexity in response to shareholder demands, competition
in the industry and the changing regulatory environment. In performing their
evaluation, the Directors considered information received in connection with the
annual review, as well as information provided on an ongoing basis at their
regularly scheduled board and committee meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management services
provided is quite complex and allows fund shareholders access to professional
money management, instant diversification of their investments within an asset
class, the opportunity to easily diversify among asset classes, and liquidity.
In evaluating investment performance, the board expects the advisor to manage
the funds in accordance with its investment objective and approved strategies.
In providing these services, the advisor utilizes teams of investment
professionals (portfolio managers, analysts, research assistants, and securities
traders) who require extensive information technology, research, training,
compliance and other systems to conduct their business. At each quarterly
meeting the Directors review investment performance information for the funds,
together with comparative information for appropriate benchmarks and a peer
group of funds managed similarly to the funds. If performance concerns are
identified, the Directors discuss with the advisor and its portfolio managers
the reasons for such results (e.g., market conditions, security selection) and
any efforts being undertaken to improve performance. Annually, the Directors
review detailed performance information, as provided by the Independent

                                                                  (continued)

15(c) Providers, comparing the funds' performance with that of similar funds not
managed by the advisor. Life Science's performance was above the median of its
peer group for the one year period and below the median of its peer group for
the three year period during part of the past year. Technology's performance was
below the median of its peer group for the one year period and above the median
of its peer group for the three year period during part of the past year. The
Directors discussed the funds' performance with the advisor and were satisfied
with the efforts being undertaken by the advisor. The Directors will continue to
monitor those efforts and the performance of the funds.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at its regular
quarterly meetings, including the annual meeting concerning contract review.
These reports include, but are not limited to, information regarding the
operational efficiency and accuracy of the shareholder and transfer agency
services provided, staffing levels, shareholder satisfaction (as measured by
external as well as internal sources), technology support, new products and
services offered to fund shareholders, securities trading activities, portfolio
valuation services, auditing services, and legal and operational compliance
activities. Certain aspects of shareholder and transfer agency service level
efficiency and the quality of securities trading activities are measured by
independent third party providers and are presented in comparison to other fund
groups not managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various services
to the funds, its profitability in managing the funds, its overall
profitability, and its financial condition. The Directors have reviewed with the
advisor the methodology used to prepare this financial information. This
financial information regarding the advisor is considered in order to evaluate
the advisor's financial condition, its ability to continue to provide services
under the management agreement, and the reasonableness of the current management
fee.

ETHICS OF THE ADVISOR. The Directors generally considered the advisor's
commitment to providing quality services to shareholders and to conducting its
business ethically. They noted that the advisor's practices generally meet or
exceed industry best practices and that the advisor was not implicated in the
industry scandals of 2003 and 2004.

ECONOMIES OF SCALE. The Directors review reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes in
revenue, costs, and profitability. The Directors concluded that economies of
scale are difficult to measure with precision, particularly on a fund-by-fund
basis. This analysis is further complicated by the fact that the advisor is
required to make a continuing reinvestment in the business to provide additional
content and services for fund shareholders. Accordingly, the Directors also seek
to evaluate economies of scale by reviewing other information, such as
year-over-year profitability of the advisor generally, the profitability of

                                                                    (continued)

its management of the funds specifically, the expenses incurred by the advisor
in providing various services to the funds, and the breakpoint fees of
competitive funds not managed by the advisor. The Directors believe the advisor
is appropriately sharing any economies of scale through a competitive fee
structure, through breakpoints that reduce fees as the fund increases in size,
and through reinvestment in its business to provide shareholders additional
content and services.

COMPARISON TO OTHER FUNDS' FEES. The funds pay the advisor a single,
all-inclusive (or unified) management fee for providing all services necessary
for the management and operation of the funds, other than brokerage expenses,
taxes, interest, extraordinary expenses, and the fees and expenses of the funds'
independent directors (including their independent legal counsel). Under the
unified fee structure, the advisor is responsible for providing all investment
advisory, custody, audit, administrative, compliance, recordkeeping, marketing
and shareholder services, or arranging and supervising third parties to provide
such services. By contrast, most other fund groups are charged a variety of
fees, including an investment advisory fee, a transfer agency fee, an
administrative fee, distribution charges and other expenses. Other than their
investment advisory fees and Rule 12b-1 distribution fees, all other components
of the total fees charged by these other fund groups may be increased without
shareholder approval. The board believes the unified fee structure is a benefit
to fund shareholders because it clearly discloses to shareholders the cost of
owning fund shares, and, since the unified fee cannot be increased without a
vote of fund shareholders, it shifts to the advisor the increased costs of
operating the funds and the risk of administrative inefficiencies. Part of the
Directors' analysis of fee levels involves comparing the funds' unified fee to
the total expense ratio of other funds in the funds' peer group. The unified fee
charged to Life Sciences' shareholders was above the median of the total expense
ratio of its peer group. The unified fee charged to Technology's shareholders
was below the median of the total expense ratio of its peer group.

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services to
advisory clients other than the funds. They observed that these varying types of
client accounts require different services and involve different regulatory and
entrepreneurial risks than the management of the funds. The Directors analyzed
this information and concluded that the fees charged and services provided to
the funds were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the funds. They concluded that the advisor's primary business
is managing mutual funds and it generally does not use fund or shareholder
information to generate profits in other lines of business, and therefore does
not derive any significant collateral benefits from them. The Directors noted
that the advisor receives proprietary research from broker dealers that

                                                                   (continued)

execute fund portfolio transactions and concluded that this research is likely
to benefit fund shareholders. The Directors also determined that the advisor is
able to provide investment management services to clients other than the funds,
at least in part, due to its existing infrastructure built to serve the fund
complex. The Directors concluded, however, that the assets of those other
clients are not material to the analysis and in any event are added to the
assets of the funds within the fund complex that use substantially the same
investment management team to determine whether each fund has reached
breakpoints in its fee schedule.

CONCLUSIONS OF THE DIRECTORS

As a result of this process, the independent directors, assisted by the advice
of legal counsel independent of the advisor, taking into account all of the
factors discussed above and the information provided by the advisor, negotiated
changes to the breakpoint schedule used to calculate the management fee. These
changes were proposed by the Directors based on their review of the competitive
changes in the mutual fund marketplace and their review of financial information
provided by the advisor. The new schedule, effective July 29, 2005, will
accelerate management fee reductions at lower asset levels than under the
existing structure. Following these negotiations with the advisor, the
independent directors concluded that the investment management agreements
between the funds and the advisor, amended as described above, are fair and
reasonable in light of the services provided and should be renewed.

Share Class Information

Four classes of shares are authorized for sale by Life Sciences: Investor Class,
Institutional Class, Advisor Class and C Class. Three classes of shares are
authorized for sale by Technology: Investor Class, Institutional Class and
Advisor Class. The total expense ratio of Institutional Class shares is lower
than that of Investor Class shares. The total expense ratios of Advisor and C
Class shares are higher than that of Investor Class shares.

INVESTOR CLASS shares are available for purchase in two ways: 1) directly from
American Century without any commissions or other fees; or 2) through certain
financial intermediaries (such as banks, broker-dealers, insurance companies and
investment advisors), which may require payment of a transaction fee to the
financial intermediary.

INSTITUTIONAL CLASS shares are available to large investors such as endowments,
foundations, and retirement plans, and to financial intermediaries serving these
investors. This class recognizes the relatively lower cost of serving
institutional customers and others who invest at least $5 million ($3 million
for endowments and foundations) 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 unified management fee
of Institutional Class shares is 0.20% less than the unified management fee of
Investor Class shares.

ADVISOR CLASS shares are sold primarily through institutions such as investment
advisors, banks, broker-dealers, insurance companies, and financial advisors.
Advisor Class shares are subject to a 0.50% annual Rule 12b-1 service and
distribution fee. The total expense ratio of Advisor Class shares is 0.25%
higher than the total expense ratio of Investor Class shares.

C CLASS shares are sold primarily through employer-sponsored retirement plans
and through institutions such as investment advisors, banks, broker-dealers, and
insurance companies. C Class shares redeemed within 12 months of purchase are
subject to a contingent deferred sales charge (CDSC) of 1.00%. There is no CDSC
on shares acquired through reinvestment of dividends or capital gains. The
unified management fee for C Class shares is the same as for Investor Class
shares. C Class shares also are subject to a Rule 12b-1 service and distribution
fee of 1.00%.

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

Additional Information

RETIREMENT ACCOUNT INFORMATION

As required by law, any distributions you receive from an IRA or certain 403(b),
457 and qualified plans [those not eligible for rollover to an IRA or to another
qualified plan] are subject to federal income tax withholding, unless you elect
not to have withholding apply. Tax will be withheld on the total amount
withdrawn even though you may be receiving amounts that are not subject to
withholding, such as nondeductible contributions. In such case, excess amounts
of withholding could occur. You may adjust your withholding election so that a
greater or lesser amount will be withheld.

If you don't want us to withhold on this amount, you must notify us to not
withhold the federal income tax. 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 notice not to withhold federal
income tax prior to the withdrawal. You may notify us in writing or in certain
situations by telephone or through other electronic means. You have the right to
revoke your withholding election at any time and any election you make may
remain in effect until revoked by filing a new election.

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.

State tax will be withheld if, at the time of your distribution, your address is
within one of the mandatory withholding states and you have federal income tax
withheld. State taxes will be withheld from your distribution in accordance with
the respective state rules.

          pre-approves its accountant's  engagements for non-audit services with
          the  registrant's  investment  adviser,  its parent  company,  and any
          entity  controlled  by, or under common  control  with the  investment

          recent fiscal year that were  attributed to work  performed by persons

          was less than 50%.

(g)       The aggregate non-audit fees billed by the registrant's accountant for
          services rendered to the registrant,  and rendered to the registrant's
          investment  adviser  (not  including  any  sub-adviser  whose  role is
          primarily  portfolio  management and is subcontracted with or overseen
          by another investment adviser), and any entity controlling, controlled
          by, or under common  control with the adviser  that  provides  ongoing

          the registrant were as follows:

          adviser,  its parent company,  and any entity  controlled by, or under
          common control with the investment  adviser that provides  services to
          the  registrant,  which services were not required to be  pre-approved
          pursuant to paragraph  (c)(7)(ii) of Rule 2-01 of Regulation  S-X. The
          notification  provided to the  registrant's  audit committee  included
          sufficient  details  regarding such services to allow the registrant's
          audit  committee  to  consider  the  continuing  independence  of  its
          principal accountant.
