REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
To the Board of Trustees of
SEI Index Funds:
In planning and performing our audit of the financial statements of SEI Index
Funds for the year ended March 31, 1997, 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 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 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, 1997.
This report is intended solely for the information and use of management, the
Board of Trustees and the Securities and Exchange Commission and should not
be used for any other purpose.
