General ACCAPER signed by CHief FInancial Officer

Short answer is "not if he's not"! The only alternative to a member of an IFAC member body is that he is a member of a body recognised by law in your country. Someone cannot be qualified by position alone (however "high") if they are not a member of a professional body.

You can then nominate a second, qualified, practical experience supervisor to work with your line manager to sign-off your performance objectives"
