Report of Independent Accountants
To the Trustees and Shareholders of the American Century Quantitative
Equity Funds: In planning and performing our audits of the financial statements
and financial highlights of the American Century Quantitative Equity Funds (the
"Funds") for the year ended December 31, 1999, 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, 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 controls may become inadequate
because of changes in conditions or that the effectiveness of their 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 December 31, 1999. This report is intended solely for the
information and use of the Board of Directors, management and the Securities and
Exchange Commission and is not intended to be and should not be used by anyone
other than these specified parties.
