The Trustees and Shareholders
Keystone State Tax Free Fund
In Planning and performing our audit of the financial statements of Keystone
State Tax Free Fund, (including Keystone Florida Tax Free Fund, Keystone
Massachusetts Tax Free Fund, Keystone New York Insured Tax Free Fund, Keystone
Pennsylvania Tax Free Fund and Keystone Texas Tax Free Fund) for the year ended
March 31, 1996, we considered its internal control structure, including
procedures for safeguarding securities, in order to determine our auditing
procedures for the purpose of expressing an opinion on the financial statements
and to comply with the requirements of Form N-SAR, not to provide assurance on
the internal control structure.
The management of Keystone State Tax Free Fund is responsible for establishing
and maintaining an internal control structure. In fulfilling this
responsibility, estimates and judgements made by management are required to
assess the expected benefits and related costs of internal control structure
policies and procedures. Two of the objectives of an internal control structure
are to provide management with reasonable, but not absolute, assurance that
assets are safeguarded against loss from unauthorized use or disposition and
that transactions are executed in accordance with management's authorization and
recorded properly to permit preparation of financial statements in conformity
with generally accepted accounting principles.
Because of inherent limitations in any internal control structure, errors and
irregularities may occur and not be detected. Also, projection of any evaluation
of the structure of 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 structure would not necessarily
disclose all matters in the internal control structure 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 the specific internal control structure elements does not reduce to
a relatively low level the risk that errors or irregularities 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 internal control structure, including procedures for safeguarding
securities, that we consider to be material weaknesses as defined above as of
March 31, 1996.
This report is intended solely for the information and use of management and the
Securities and Exchange Commission.
