Auditor appointment is more complicated in the case of multi-location audits(see'multi-location audits'below),as in this situation the group auditor will need to perform and/or coordinate audits of components of the group (subsidiaries,etc.) to support the group audit opinion. The component audits may be performed by the lead audit firm (i.e. the firm providing an opinion on the group's consolidated financial information) , by another audit firm in the lead auditor's network, or by another unconnected audit firm. The auditors of those components report to the lead auditor of the group for the purpose of the consolidated group financial statements.The lead auditor typically has sole responsibility for the audit opinion on the consolidated financial statement.
