SIGNATURE GEORGE R. JAY
TITLE CONTROLLER
To the Shareholders and Board of Directors of
Hartford Mortgage Securities HLS Fund, Inc.
In planning and performing our audit of the financial
statements of Hartford Mortgage Securities HLS Fund,
Inc. (the Fund) 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.
