Report of Independent Registered Public
 Accounting Firm

To the Board of Trustees and Shareholders
of Advent Claymore Convertible Securities
and Income Fund

In planning and performing our audit of
the financial statements of Advent
Claymore Convertible Securities and Income
Fund (the Fund) as of and for the year
ended October 31 2015 in accordance with
the standards of the Public Company
Accounting Oversight Board (United States)
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-SAR but not for
the purpose of expressing an opinion on the
effectiveness of the Funds internal control
over financial reporting. Accordingly we do
not express an opinion on the effectiveness
of the Funds internal control over financial
reporting.

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 funds
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 funds 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 funds 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 Funds 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 over financial reporting that might
be material weaknesses under standards established
by the Public Company Accounting Oversight Board
(United States). However we noted no deficiencies
in the Funds internal control over financial
reporting and its operation including controls over
safeguarding securities that we consider to be
material weaknesses as defined above as of October
31 2015.

This report is intended solely for the information
and use of management and the Board of Trustees of
Advent Claymore Convertible Securities and Income
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.
