……… is an audit on a legal entity

Solution

A joint audit is an audit on a legal entity (the auditee ) by two or more auditors to produce a single audit report, thereby sharing responsibility for the audit. A typical joint audit has audit planning performed jointly and fieldwork allocated to the auditors. A joint audit is different from a dual audit, where a dual audit is performed by two independent auditors issuing their own separate reports, which are then used by another auditor that ultimately reports on the entity as a whole.
