Abstract
Although auditing standards instruct auditors to avoid issuing standardised key audit matters (KAMs), standard setters warn and financial statement users worry about expanded auditor's reports becoming sticky, generic and boilerplate over time. Based on textual analysis of expanded auditor's reports from the UK, I provide longitudinal evidence of an increase in various textual similarity measures including year‐over‐year similarity (stickiness), within‐peer group similarity (generality) and boilerplate language over time. Next, I identify a number of crucial drivers of convergence and find that disclosure similarity diminishes the positive capital market effect of precise KAM reporting documented in prior studies. Together, these findings suggest that audit firms have successively developed standard text modules for KAM reporting that undermine the aim of expanded auditor's reports to provide informative value. This paper extends the literature on the relationship between institutional environments and unintended effects of auditor disclosure regulation.
