Independant Auditors Report
October 21, 1998
To the Board of Trustees of
Oppenheimer Insured Municipal Fund:
In planning and performing our audit of the financial statements of Oppenheimer
Insured Municipal Fund (the "Fund") for the year ended September 30, 1998 (on
which we have issued our report dated October 21, 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, and not to provide assurance on the Fund's internal control.
The management of the Fund 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 Fund'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 errors 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 Fund's internal control and its operation, including controls for
safeguarding securities, that we consider to be material weaknesses as defined
above as of September 30, 1998.
This report is intended solely for the information and use of management, the
Board of Trustees of Oppenheimer Insured Municipal Fund, and the Securities and
Exchange Commission.
Yours truly,
