 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">To the shareholders and the Board of Trustees of Calamos Global Total Return Fund </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In planning and performing our audit of the financial statements of Calamos Global Total Return Fund (the &#147;Fund&#148;) as of and for the year ended
October&nbsp;31, 2018, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), we considered the Fund&#146;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 <FONT STYLE="white-space:nowrap">N-CEN,</FONT> but not for the purpose of
expressing an opinion on the effectiveness of the Fund&#146;s internal control over financial reporting. Accordingly, we express no such opinion. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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 fund&#146;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&#146;s internal control over financial reporting includes those policies and procedures that (1)&nbsp;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)&nbsp;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)&nbsp;provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of a fund&#146;s assets that could have a material effect on the financial statements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">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&#146;s annual or interim financial statements will not be prevented or
detected on a timely basis. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our consideration of the Fund&#146;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 PCAOB. However, we noted no deficiencies in the Fund&#146;s 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&nbsp;31, 2018. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This report is intended solely for the information and use of management and the Board of Trustees of the Fund and the Securities and Exchange Commission and
is not intended to be and should not be used by anyone other than these specified parties. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">[<I>Signature</I>] </P>
