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, 2019, 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, 2019.

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.
