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,
1999, 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, 1999.
This report is intended solely for the information and
use of management, the Board of Directors and the
Securities and Exchange Commission.
