Report of Independent Auditors
To the Shareholders and Board of Trustees of
SAFECO Common Stock Trust
In planning and performing our audit of the financial statements
of SAFECO Common Stock Trust (comprising, respectively, the
SAFECO Growth Fund, SAFECO Equity Fund, SAFECO Income Fund,
SAFECO Northwest Fund, SAFECO International Stock Fund, SAFEO
Balanced Fund, SAFECO Small Company Stock Fund, and SAFECO U.S.
Value Fund) for the year ended December 31, 1997, 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, not to provide assurance on the internal control.
The management of SAFECO Common Stock 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 internal control, errors 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 because the effectiveness of the design and
operation may deteriorate.
Our consideration of the internal control would not necessarily
disclose all matters in the 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 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, at December 31, 1997, we noted no matters involving the
internal control and its operation, including controls for
safeguarding securities, that we consider to be material
weaknesses as defined above.
This report is intended solely for the information and use of the
Board of Directors, management of SAFECO Common Stock Trust, and
the Securities and Exchange Commission.
