SIGNATURE KRISTI L. ROWSELL
TITLE ASSISTANT TREASURER
To the Board of Directors of the
Harris Associates Investment Trust:
In planning and performing our audit of the financial statements of the HARRIS
ASSOCIATES INVESTMENT TRUST, comprised of The Oakmark Fund,
The Oakmark Select Fund, The Oakmark Small Cap Fund, The Oakmark
Equity and Income Fund, The Oakmark International Fund and The Oakmark
International Small Cap Fund (the "Funds"), for the period ended September 30,
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, and not to provide assurance
on the internal control structure.
The management of the 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 the 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 September 30, 1997.
This report is intended solely for the information and use of management and the
Securities and Exchange Commission.
