REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the shareholders and the Board of Trustees of Calamos Convertible
Opportunities and Income Fund, Calamos Convertible and High Income Fund,
Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and Income
Fund, Calamos Global Dynamic Income Fund, Calamos Global Total Return Fund, and
Calamos Long/Short Equity & Dynamic Income Trust
In planning and performing our audits of the financial statements of Calamos
Convertible Opportunities and Income Fund, Calamos Convertible and High Income
Fund, Calamos Strategic Total Return Fund, Calamos Dynamic Convertible and
Income Fund, Calamos Global Dynamic Income Fund, Calamos Global Total Return
Fund, and Calamos Long/Short Equity & Dynamic Income Trust ( each a “Fund”; collectively, the
“Funds”) as of
and for the year ended October 31, 2024, in accordance with the standards of
the Public Company Accounting Oversight Board (United States) (PCAOB), we
considered the Funds’ 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 Funds’ internal
control over financial reporting. Accordingly, we express no such opinion.
The management of the Funds are 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 fund'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 generally
accepted accounting principles. A fund'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 fund; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the fund
are being made only in accordance with authorizations of management and trustees
of the fund; and (3) provide reasonable assurance regarding prevention or
timely detection of unauthorized acquisition, use, or disposition of a fund'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
fund's annual or interim financial statements will not be prevented or detected
on a timely basis.
Our consideration of the Funds’ 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 PCAOB. However, we noted
no deficiencies in the Funds’ internal control over financial reporting and its
operation, including controls for safeguarding securities, that we consider to
be a material weakness, as defined above, as of October 31, 2024.
This report is intended solely for the information and use of management and
the Board of Trustees of the Funds and the Securities and Exchange Commission
and is not intended to be and should not be used by anyone other than these
specified parties.
