Once additional procedures have been completed after issuance of the final communication, the engagement supervisor should report the resulting information to the chief audit executive. The CAE is responsible for determining whether the significance of the additional evidence requires revised or supplemental communication to appropriate recipients. Automatically updating the report regardless of the results may be unnecessary, while limiting updates only to adverse findings ignores the possibility that other significant information could affect previously communicated conclusions. Option D incorrectly assumes that the original communication necessarily contained errors or omissions; the scenario states only that additional work became necessary. Therefore, the appropriate governance process is for the supervisor to escalate the completed additional work and its results to the CAE, who can evaluate materiality and determine whether further communication is required.
