Report of Independent Accountants
To the Board of Trustees of
SEI Asset Allocation Trust:
In planning and performing our audit of the financial
statements of SEI Asset Allocation Trust (the "Trust"),
for the year ended March 31, 2000, 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 controls.
Generally, controls 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 controls include the
safeguarding of assets against unauthorized acquisition,
use or disposition.
Because of inherent limitations in internal control,
errors or fraud 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 one or more of
the internal control components does not reduce to a
relatively low level the risk that misstatements caused
by error or fraud 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 and its operation, including controls
for safeguarding securities that we consider to be
material weaknesses as defined above as of
March 31, 2000.
This report is intended solely for the information and
use of management, the Board of Trustees of the Trust
and the Securities and Exchange Commission.
