The following unrelated events occurred after the balance sheet date but before the audit report was prepared:

 The granting of a retroactive pay increase

 Determination by the federal government of additional income tax due for a prior year

 Filing of an antitrust suit by the federal government

 Declaration of a stock dividend

 Sale of a fixed asset at a substantial profit

How each of the above items might have come to the auditor’s attention? Why is it the auditor’s responsibility to recognize each of these in connection with the audit report and opinion?
