Board of Trustees
SEI Index Funds:
In planning and performing our audit of the financial statements of SEI
Index Funds for the year ended March 31, 1995, we considered its
internal control structure, including procedures 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 the internal
control structure.
The management of SEI Index Funds is responsible for establishing and
maintaining an internal control structure. 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 recorded properly to permit
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 may not be detected. Also, projection
of any evaluation of the structure 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 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 matters involving the
internal control structure, including procedures for safeguarding
securities, that we consider to be material weaknesses as defined above
as of March 31, 1995.
This report is intended solely for the information and use of management,
the Board of Trustees amd the Securities and Exchange Comission and
should not be used for any other purpose.
