It is a matter for the certifying officers’ judgment whether the following situations indicate that a deficiency in ICFR exists and, if so, whether it represents a material weakness:
(a) identification of fraud, whether or not material, on the part of the certifying officers or other senior management who play a significant role in the issuer’s financial reporting process;
(b) restatement of previously issued financial statements to reflect the correction of a material misstatement;
(c) identification by the issuer or its external auditor of a material misstatement in the financial statements in the current period in circumstances that indicate that the misstatement would not have been detected by the issuer’s ICFR; and
(d) ineffective oversight of the issuer’s external financial reporting and ICFR by the issuer’s audit committee.
