control structure, including procedures for safeguarding securities, in
order to determine our auditing procedures for the purpose of
expressing our opinion on the financial staements and to comply with
the requirementso fo Form N-SAR, not to provide assurance on the
internal control structure.
The management of IDS Money Market Series, Inc. is responsible for
establishing and maintaining a system of internal accounting control.
In fulfilling this responsibility, estimates and judgments by
management are required to assess the expected benefits and related
costs of internal control structure policies and procedures. Two of
the objectives of an internal control structure are to provide
management with reasonable, but not absolute, assurance that assets
are safeguarded against loss from unauthorized use or disposition and
that transactions are executed in accordance with management's
authorization and recoreded properly to permit the preparation of
financial statements in conformity with generally accepted accounting
principles.
Because of inherent limitations in any internal control structure,
errors or irregularities may occur and not be detected. Also, projection
of any evaluation of the structure to futrue periods is subject to the
risk that it may become inadeequate because of changes in conditions
or that the effectiveness of the design and operation may deteriorate.
Our consideration of the internal control structure would not necessarily
disclose all matters in the internal control structure 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 the specific internal
control structure elements does not reduce to a relatively low level the
risk that errors or irregularities 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 matter
involving the internal control structure, including procedures for
safeguarding securites, that we consider to be a material weakness as
defined above as of July 31, 1996.
