Report of Independent Registered Public
Accounting Firm

To the Shareholders and Board of Trustees of AB
Growth Fund:

In planning and performing our audit of the
financial statements of AB Growth Fund, (the
"Fund"), (one of the series constituting The AB
Portfolios, as of and for the year ended July 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 trustees 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 July 31, 2020.

This report is intended solely for the information
and use of management and the Board of Trustees
of AB Growth 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.
