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 statements.
