TITLE AVP
Report of Independent Auditors
To the Shareholders and Board of Directors of
The Munder Funds, Inc.
In planning and performing our audit of the financial statements of The
Munder Funds, Inc. (comprising, respectively, the Munder All-Season
Aggressive, Munder All-Season Conservative, Munder All-Season Moderate,
Munder Growth Opportunities, Munder Equity Selection, Munder Micro-Cap
Equity, Munder Multi-Season Growth, Munder NetNet, Munder Real Estate
Equity Investment, Munder Small-Cap Value, Munder Value, Munder
International Bond, Munder Short Term Treasury, and Munder Money Market
Funds) for the year ended June 30, 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, and not to provide assurance on the internal
control.
The management of The Munder Funds, Inc. 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 specific internal control components
does not reduce to a relatively low level the risk that errors 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 at June 30, 1999.
This report is intended solely for the information and use of the board
of directors and management of The Munder Funds, Inc. and the Securities
and Exchange Commission and is not intended to be and should not be used
by anyone other than these specified parties.
