Report of Independent Certified Public Accountants on Internal Control Structure
Board of Directors
First Investors Series Fund
New York, New York
In planning and performing our audit of the financial statements of First
Investors Series Fund for the year ended December 31, 1999, we considered its
internal control structure, including procedures for safeguarding securities,
in order to determine our auditing procedures for the purpose of expressing
our opinion on the financial statements and to comply with the requirements
of Form N-SAR, not to provide assurance on the internal control structure.
The management of the Fund is responsible for establishing and maintaining an
internal control structure. In fulfilling this responsibility, estimates and
judgments by management are required to assess the expected benefits and
related costs of internal control policies and procedures. Two of the
objectives of an internal control structure are to provide management with
reasonable, but not absolute, assurance that assets are safeguarded against
loss from unauthorized use or disposition, and that transactions are executed
in accordance with management's authorization and recorded properly to permit
preparation of financial statements in conformity with generally accepted
accounting principles.
Because of inherent limitations in any internal control structure, errors or
irregularities may occur and not be detected. Also, projection of any
evaluation of the structure to future periods is subject to the risk that it
may become inadequate because of changes in conditions or that the
effectiveness of the design and operation may deteriorate.
Our consideration of the internal control structure would not necessarily
disclose all matters in the internal control structure that might be material
weakness under standards established by the American Institute of Certified
Public Accountants. A material weakness is a condition in which the design
or operation of the specific internal control structure elements does not
reduce to a relatively low level the risk that errors or irregularities in
amounts that would be material in relation to the financial statements being
audited may occur and not be detected within a timely period by employees in
the normal course of performing their assigned functions. However, we noted
no matters involving the internal control structure, including procedures for
safeguarding securities, that we consider to be material weaknesses, as
defined above, as of December 31, 1999.
This report is intended solely for the information and use of management and
the Securities and Exchange Commission, and should not be used for any other
purpose.
