an audit report is the output of an audit and can be a sign of audit quality. empirical studies have also used an auditor's opinion as a surrogate of audit quality , especially a going-concern audit report (e.g. carey and simnett,2006; and reichelt and wang, 2010). carey and simnett (2006) preusmed that long audit partner tenure might lead tothe would give going concern audit report to their clients even when those clients faced financial difficulties. this in turn impairs audit quality.
