INDEPENDENT AUDITORS' REPORT
TO THE BOARD OF TRUSTEES AND SHAREHOLDERS OF
MOSAIC FOCUS FUND:
In planning and performing our audits of the financial statements of Mosaic
Focus Fund (the "Fund") for the year ended December 31, 1999, (on which we
have issued our report dated February 15, 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 Fund's internal control.
The management of the Fund 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
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
deteriorates.
Our consideration of the Fund'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 Fund's 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 management,
the Board of Trustees of Mosaic Focus Fund, and the Securities and Exchange
Commission and is not intended to be and should not be used by anyone other
than these specified parties.
