Report of Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders of Putnam Convertible
Securities Fund

In planning and performing our audit of the financial statements of
Putnam Convertible Securities Fund (the Fund) as of and for the year
ended October 31, 2021, 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 NCEN, 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 companys 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 companys 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 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 companys 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 companys 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 PCAOB.  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, 2021.

of Trustees of Putnam Convertible Securities Fund and the Securities and
Exchange Commission and is not intended to be and should not be used by
