SIGNATURE GEORGE R. JAY
TITLE CONTROLLER
To the Shareholders and Board of Directors of
Hartford Series Fund, Inc.
In planning and performing our audit of the financial
statements of Hartford Series Fund, Inc. (consisting
of Hartford Global Leaders HLS Fund, Hartford Growth
and Income HLS Fund and Hartford High Yield HLS
Fund) (the Funds) for the year ended December 31,
1998, we considered its internal control, including
control activities 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 internal control.
The management of the Funds is responsible for
establishing and maintaining internal control. In
fulfilling this responsibility, estimates and judgments
by management are required to assess the expected
benefits and related costs of controls. Generally,
controls that are relevant to an audit pertain to the
entity's objective of preparing financial statements for
external purposes that are fairly presented in conformity
with generally accepted accounting principles. Those
controls include the safeguarding of assets against
unauthorized acquisition, use or disposition.
Because of inherent limitations in internal control,
error or fraud may occur and not be detected. Also,
projection of any evaluation of internal control 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 internal control would not
necessarily disclose all matters in internal control
that might be material weaknesses under standards
established by the American Institute of Certified
Public Accountants. A material weakness is a condition
in which the design or operation of one or more of the
internal control components does not reduce to a
relatively low level the risk that misstatements caused
by error or fraud 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 internal control and its operation, including
controls for safeguarding securities, that we consider
to be material weaknesses as defined above as of
December 31, 1998.
This report is intended solely for the information
and use of management and the Securities and
Exchange Commission.
