Busy auditors, financial reporting timeliness and quality

We investigate whether audit partners with multiple clients are able to complete their audits in a timely fashion, an important but largely unexplored area of academic research. One view is that having multiple clients increases the knowledge and experience of the audit partner resulting in a more efficient and therefore, quicker audit. On the other hand, having multiple clients may over-burden an audit partner resulting in a slower audit process and longer completion times. We find that audit partners with multiple clients take longer to complete their annual audit. More importantly, we also find that companies with busy auditors who take longer to complete their audits also have poorer levels of financial reporting quality. Additionally, in terms of consequences for busy auditors, firms with lengthy audit report lag switched their auditors the next year suggesting that busy audit partners may lose clients if their workload is excessive and they are not able to maintain audit quality. Our results are robust to alternative measures for both audit report lag and audit partner busyness and a range of endogeneity tests. We also undertake simultaneous quantile regression to assess changes in audit report lag depending on the number of audit clients per partner where we find preliminary evidence of a knowledge spill-over effect. Consequently, our results have implications for companies, audit firms, regulators and other key stakeholders.
