The Office of Government Ethics is amending the regulation governing confidential financial disclosure for executive branch employees, to update the standardized confidential disclosure report form's designation as OGE Form 450, which is replacing the Standard Form (SF) 450; and to provide authority for all executive branch agencies to adopt and use a standardized certificate of no new interests (OGE Optional Form 450-A) as an alternative procedure in lieu of OGE Form 450, for regular employee annual confidential disclosure filers who can make the required certifications.
