The Board of Trustees of
Money Market Portfolio:
In planning and performing our audit of the financial
statements of Money Market Portfolio 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 Money Market Portfolio 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 any 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 the 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 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 operations, including controls for
safeguarding securities, that we consider to be material
weaknesses as defined above as of December 31, 1998.
