Review of Independent Registered Public Accountant Reports
The Audit Committee reviews the independent registered public accountant reports on the Corporation's financial statements. The Committee discusses with the independent registered public accountant judgments about the quality (not just the acceptability) of the accounting principles used in the Corporation's financial reporting. The Committee also reviews the scope of audits conducted by the Corporation's independent registered public accountant. The Committee reviews with the independent registered public accountant any difficulties encountered in the audit work, including any restrictions on the scope of the independent registered public accountant's activities or on access to requested information, any significant disagreements with management and management's response, and addresses those as the Committee deems appropriate. The Committee may review with the auditor: any accounting adjustments that were noted; any significant communications between the audit team and the auditor's national office respecting auditing or accounting issues presented by the engagement; any "management" or "internal control" letter issued or proposed by the auditor to the Corporation; and any other issues regarding the auditor report that the Committee may deem appropriate.
