INDEPENDENT AUDITORS' REPORT
To the Trustees and Shareholders of WM Money Market Fund, WM Tax-Exempt Money
Market Fund and WM California Money Fund:
In planning and performing our audits of the financial statements of WM Money
Market Fund, WM Tax-Exempt Money Market Fund and WM California Money Fund
(collectively the "Funds") for the year ended October 31, 2000 (on which we
have issued our report dated December 8, 2000), 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, and not to provide assurance on the Funds' 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 generally accepted in the United States of America.
Those controls include the safeguarding of assets against unauthorized
acquisition, use, or disposition.
Because of inherent limitations in any internal control, misstatements due
to 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 may deteriorate.
Our consideration of the Funds' 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 Funds' internal control and its
operation, including controls for safeguarding securities that we consider to
be material weaknesses as defined above as of October 31, 2000.
This report is intended solely for the information and use of management,
the Trustees and Shareholders of the Funds, and the Securities and Exchange
Commission and is not intended to be and should not be used by anyone other
than these specified parties.
