Report of Independent Registered Public
Accounting Firm

To the Shareholders and Board of Directors of AB
Variable Products Series Fund, Inc.

In planning and performing our audits of the
financial statements of AB Variable Products Series
Fund, Inc. (the "Fund") (comprising the AB Global
Thematic Growth Portfolio, AB Intermediate Bond
Portfolio, AB Dynamic Asset Allocation Portfolio,
AB Global Risk Allocation-Moderate Portfolio, AB
Large Cap Growth Portfolio, AB International
Value Portfolio, AB International Growth Portfolio,
AB Growth and Income Portfolio, AB Small/Mid
Cap Value Portfolio, AB Small Cap Growth
Portfolio, and AB Balanced Wealth Strategy
Portfolio) as of and for the year ended December
31, 2019, 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 opinions 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 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 U.S. 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 U.S. generally
accepted accounting principles, and that receipts
and expenditures of the fund are being made only in
accordance with authorizations of management and
directors 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 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 December 31,
2019.

This report is intended solely for the information
and use of management and the Board of Directors
of AB Variable Products Series Fund, Inc and the
Securities and Exchange Commission and is not
intended to be and should not be used by anyone
other than these specified parties.
