our report dated December 13, 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, and not to
provide assurance on the Trust's 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 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, misstatements due to error
or fraud may occur and not be detected.
Also, projections of any evaluation of
internal control to future periods are
subject to the risk that the internal
control may become inadequate because of
changes in conditions or that degree of
compliance with policies or procedures may
deteriorate.
Our consideration of the Trust's 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 the Trust's internal control and
its operation, including controls for
safeguarding securities, that we consider to
be material weaknesses as defined above as
of October 31, 1999.
