To the Trustees of
SEI Liquid Asset Trust
In planning and performing our audit of the financial statements of
SEI Liquid Asset Trust ("the Trust") for the year ended June 30, 1997,
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, not to provide
assurance on internal control.
The management of the Trust 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 control activities. Generally, control activities 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 control activities include the
safeguarding of assets against unauthorized acquisition, use or disposition.
Because of inherent limitations in internal control, errors or irregularities
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 any specific internal control components 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 internal control, including control
activities for safeguarding securities, that we consider to be material
weaknesses as defined above as of June 30, 1997.
This report is intended solely for the information and use of management
and the Securities and Exchange Commission.
