The limitations of an audit which are documented in an engagement letter pertain to
each of the following except:
(a) material errors or illegal activities having a direct and material financial statement
impact may not be detected because of the judgmental nature of many audit areas and
the fact that detailed tests are not performed for all types of transactions.
(b) fraudulent activities having a direct and material financial statement impact may not
be detected because of the nature of fraud, including the possibility of the perpetrator’s
concealment efforts and/or management’s override of controls.
(c) internal controls may change or deteriorate such that they may not be effective in the
prevention or detection of future material misstatements in the financial statements.
(d) under the standards established by the PCAOB, the auditor’s responsibilities for
communicating internal control weaknesses are limited to notification to the company’s
shareholders regarding material weaknesses.
The engagement letter states that auditors are responsible for informing the client’s
audit committee about certain matters related to the conduct of the audit, including any:
(a) serious difficulties encountered in performing the audit.
(b) disagreements among audit team members pertaining to conclusions reached during
the audit.
(c) revisions made in the nature of audit tests performed as a result of information
discovered during the course of the audit.
