Report of Independent Accountants
To the Shareholders and Board of Trustees
SEI Institutional Managed Trust
In planning and performing our audit of the financial statements
of SEI Institutional Managed Trust (the "Fund'') for the year
ended September 30, 1995, we considered its internal control
structure, including procedures for safeguarding securities, in
order to determine our auditing procedures for the purposes
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 structure.
The management of the Fund 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 appropriately 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 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 September 30, 1995.
This report is intended solely for the information and use of
management and the Securities and Exchange Commission.
