Exhibit A: Attachment to item 77B:
Accountant's report on internal control.
- --------------------------------------------------------------
Exhibit A:
REPORT OF INDEPENDENT ACCOUNTANTS
To the Board of Trustees of
LaSalle Partners Master Trust
In planning and performing our audit of the financial
statements and financial highlights of the LaSalle Partners
Master Trust (the "Trust") for the period ended December
31, 1998, we considered its internal control, including
control activities safeguarding securities, in order to
determine our auditing procedures for the purpose of
expressing our opinion on the financial statements and
financial highlights and to comply with the requirements of
Form N-SAR, not to provide assurance on internal control.
The management of the Trust 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 and financial highlights 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 controls,
errors 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 errors or fraud in amounts that
would be material in relation to the financial statements
and financial highlights 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 over 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
