U.S. accounting and auditing practice to provide reasonable assurance that the
engagement was conducted in compliance with professional standards, that there
was appropriate continuity of Andersen personnel working on the audit and
availability of national office consultation. Availability of personnel at
foreign affiliates of Andersen was not relevant to this audit.

Sincerely,
