The most appropriate response for a chief audit executive (CAE) who has been asked to oversee the organization's insurance function is to report the request to the board and recommend alternate processes to obtain assurance related to insurance activities. Taking on operational responsibilities such as overseeing the insurance function could impair the objectivity and independence of the internal audit activity, making it difficult to audit those activities impartially in the future.References: IIA Standards on independence and objectivity, particularly Standard 1130: Impairment to Independence or Objectivity.
