Report of Independent
Registered Public Accounting Firm

To the Board of Trustees and Shareholders of UBS
Investment Trust

In planning and performing our audit of the financial
statements of UBS U.S. Allocation Fund (the sole fund
constituting UBS Investment Trust) (the "Company") as
of and for the period ended August 31, 2020, in
accordance with the standards of the Public Company
Accounting Oversight Board (United States), we
considered the Company's internal control over
financial reporting, including controls over safeguarding
securities, as a basis for designing our auditing
procedures for the purpose of expressing our opinion on
the financial statements and to comply with the
requirements of Form N-CEN, but not for the purpose of
expressing an opinion on the effectiveness of the
Company's internal control over financial reporting.
Accordingly, we express no such opinion.

The management of the Company is responsible for
establishing and maintaining effective internal control
over financial reporting. In fulfilling this responsibility,
estimates and judgments by management are required to
assess the expected benefits and related costs of
controls. A company's internal control over financial
reporting is a process designed to provide reasonable
assurance regarding the reliability of financial reporting
and the preparation of financial statements for external
purposes in accordance with U.S. generally accepted
accounting principles. A company's internal control
over financial reporting includes those policies and
procedures that (1) pertain to the  maintenance of
records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of
the company; (2) provide reasonable assurance that
transactions are recorded as necessary to permit
preparation of financial statements in accordance with
U.S. generally accepted accounting principles, and that
receipts and expenditures of the company are being
made only in accordance with authorizations of
management and trustees of the company; and (3)
provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use or
disposition of a company's assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in
conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

A deficiency in internal control over financial reporting
exists when the design or operation of a control does not
allow management or employees, in the normal course
of performing their assigned functions, to prevent or
detect misstatements on a timely basis. A material
weakness is a deficiency, or combination of
deficiencies, in internal control over financial reporting,
such that there is a reasonable possibility that a material
misstatement of the company's annual or interim
financial statements will not be prevented or detected on
a timely basis.

Our consideration of the Company's internal control
over financial reporting was for the limited purpose
described in the first paragraph and would not
necessarily disclose all deficiencies in internal control
that might be material weaknesses under standards
established by the Public Company Accounting
Oversight Board (United States). However, we noted no
deficiencies in the Company's internal control over
financial reporting and its operation, including controls
over safeguarding securities that we consider to be a
material weakness as defined above as of August 31,
2020.

This report is intended solely for the information and
use of management and the Board of Trustees of UBS
Investment Trust and the Securities and Exchange
Commission and is not intended to be and should not be
used by anyone other than these specified parties.
