The Trustees and Shareholders
Keystone Institutional Adjustable Rate Fund
In planning and performing our audit of the financial statements of Keystone
Institutional Adjustable Rate Fund for the year ended September 30, 1995 we
considered its internal control structure, including procedures 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, not to provide assurance on the
internal control structure.
The management of Keystone Institutional Adjustable Rate Fund is responsible
for establishing and maintaining an internal control structure. In fulfilling
this responsibility, estimates and judgments 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 or
irregularities may occur and not be detected. Also, projection of any
evaluation of the structure 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 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 September 29, 1995.
This report is intended solely for the information and use of management and
the Securities and Exchange Commission.
