Division of Investment Management

This letter is filed on behalf of the Harris Associates Investment Trust
("Trust") and each series thereunder (the "Oakmark Funds") in response
to a telephone discussion with Jeff Long, an accountant with the
U.S. Securities and Exchange Commission ("SEC"), on May 2, 2012.
All comments herein reference the Trust's Annual Report dated
September 30, 2011.

During the discussion, the SEC noted the "Growth of $10,000" line-graph for
the Oakmark Equity and Income Fund ("Fund") plotted the performance of the
Fund and the Lipper Balanced Fund Index.  The staff indicated its concern
that the Lipper Balanced Fund Index may not be an appropriate broad-based
securities market index as such term is used in Item 27(b)(7)(ii)
of Form N-1A.

We respectfully disagree with this conclusion because Instruction 5 to
Item 27(b)(7)(ii) simply provides that "[f]or purposes of this Item, an
'appropriate broad-based securities market index' is one that is administered
by an organization that is not an affiliated person of the Fund, its
investment adviser or principal underwriter, unless the index is widely
recognized and used."  We believe the Lipper Balanced Fund Index satisfies
this instruction.  It represents an index of mutual fund securities and
measures the performance of the 30 largest U.S. balanced funds, each having
a similar investment strategy as the Fund.  In addition, Lipper is a widely
recognized and used administrator of indices, and is not affiliated with
the Fund, its investment adviser or principal underwriter.  Moreover, we
believe that the Lipper Balanced Fund Index provides shareholders with
sufficient and appropriate information to evaluate the Fund's performance,
particularly in light of the performance table immediately below the
line-graph, which compares the Fund's performance with the S&P 500 Index
and the Barclays Capital U.S. Government/Credit Bond Index.

Notwithstanding our disagreement, we will consider including in the graph
additional indices, such as the S&P 500 Index and the Barclays Capital
U.S. Government/Credit Bond Index.  Because this change will impact the
Trust's disclosures beyond the Annual Report, such change will occur
in the shareholder report following the Trust's next annual update to
its Registration Statement.

Tandy Representation

The Trust acknowledges that:
* the Trust is responsible for the adequacy and accuracy of the disclosure
in the filings;
* staff comments or changes to disclosure in response to staff comments
in the filings reviewed by the staff do not foreclose the commission from
taking any action with respect to the filing; and
* the Trust may not assert staff comments as a defense in any proceeding
initiated by the Commission or any person under the federal securities
laws of the United States.


Sincerely,


Thomas Herman
