Report of Independent Registered Public
Accounting Firm
To the Shareholders and Board of Directors of Duff &
Phelps Utility and Corporate Bond Trust Inc.
In planning and performing our audit of the financial
statements of Duff & Phelps Utility and Corporate Bond
Trust Inc. (the Fund) as of and for the year ended
October 31, 2020, in accordance with the standards of
the Public Company Accounting Oversight Board
(United States), we considered the Fund'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 Fund's internal control over financial reporting.
Accordingly, we express no such opinion.
The management of the Fund 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 directors 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 a 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 Fund'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 Fund'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 October
31, 2020.
This report is intended solely for the information and
use of management and the Board of Directors of Duff
& Phelps Utility and Corporate Bond Trust Inc. and the
Securities and Exchange Commission and is not
intended to be and should not be used by anyone
other than these specified parties.
