Report of Independent Accountants
To the Trustees and Shareholders of the American Century California
Tax-Free and Municipal Funds: In planning and performing our audits of the
financial statements and financial highlights of the American Century California
Tax-Free and Municipal Funds (the "Funds") for the year ended August 31, 1999,
we considered their 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, not to provide assurance on internal control.
The management of the Funds 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
internal control, errors or fraud may occur and not be detected. Also,
projection of any evaluation of internal control to future periods is subject to
the risk that it may become inadequate because of changes in conditions or that
the effectiveness of the design and operation may deteriorate. Our consideration
of 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 caused by 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 internal control and
its operation, including controls for safeguarding securities that we consider
to be material weaknesses as defined above as of August 31, 1999. This report is
intended solely for the information and use of management and the Securities and
Exchange Commission. October 13, 1999
