INDEPENDENT AUDITORS' REPORT
The Board of Directors,
American Century World Mutual Funds, Inc.
In planning and performing our audits of the financial statements of
International Growth Fund, Global Growth Fund, International Discovery Fund, and
Emerging Markets Fund, (collectively the "Funds"), comprising American Century
World Mutual Funds, Inc. (the "Company") for the year ended November 30, 1999,
(on which we have issued our report dated January 12, 2000), we considered its
internal control, including control activities for safeguarding securities, in
order to determine our auditing procedures for the purpose of expressing our
opinion on the financial statements and to comply with the requirements of Form
N-SAR, and not to provide assurance on the Company's internal control. The
management of the Company is responsible for establishing and maintaining
internal control. In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related costs of
controls. Generally, controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for external purposes that
are fairly presented in conformity with generally accepted accounting
principles. Those controls include the safeguarding of assets against
unauthorized acquisition, use, or disposition. Because of inherent limitations
in any internal control, misstatements due error or fraud may occur and not be
detected. Also, projections of any evaluation of internal control to future
periods are subject to the risk that the internal control may become inadequate
because of changes in conditions or that the degree of compliance with policies
or procedures deteriorate. Our consideration of the Company's internal control
would not necessarily disclose all matters in internal control that might be
material weaknesses under standards established by the American Institute of
Certified Public Accountants. A material weakness is a condition in which the
design or operation of one or more of the internal control components does not
reduce to a relatively low level the risk that misstatements due to error or
fraud in amounts that would be material in relation to the financial statements
being audited may occur and not be detected within a timely period by employees
in the normal course of performing their assigned functions. However, we noted
no matters involving the Company's internal control and its operation, including
controls for safeguarding securities, that we consider to be material weaknesses
as defined above as of November 30, 1999. This report is intended solely for the
information and use of management, the Board of Directors of the Company, and
the Securities and Exchange Commission and is not intended to be and should not
be used by anyone other than these specified parties.
