To the Shareholders and Board of Directors of
Strong Municipal Bond Fund, Inc.
In planning and performing our audit of the financial statements and financial
highlights of Strong Municipal Bond Fund, Inc. (the Fund) for the year ended
August 31, 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 financial highlights and to comply with the requirements of Form N-SAR, not
to provide assurance on 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 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 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 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 August 31, 1999.
This report is intended solely for the information and use of management, the
Board of Directors of the Fund and the Securities and Exchange Commission and is
not intended to be and should not be used by anyone other than these specified
parties.
