Abstract
This study examines the association of firm size, firm complexity, and audit fees with the Key Audit Matters (KAM) disclosed in independent auditor’s reports, as well as the moderating role of auditor switching in the relationship between Firm Size and KAM disclosure. The study uses secondary data from industrial sector companies listed on the Indonesia Stock Exchange during 2022–2024. Based on purposive sampling, 46 firms were selected, yielding 138 firm-year observations. KAM disclosure is measured by the number of matters reported in the independent auditor’s report; Firm Size by the natural logarithm of total assets; Firm Complexity by the number of subsidiaries; Audit Fees by the natural logarithm of audit fees; and Auditor Switching by a binary indicator. The data are analyzed using multiple linear regression and moderated regression analysis. The results indicate that Firm Size is positively and significantly associated with KAM disclosure (B = 0.083, p = 0.024). Firm Complexity also exhibits a positive and significant association with KAM disclosure (B = 0.069, p = 0.014), whereas Audit Fees have a negative and significant association (B = −0.102, p = 0.034). Furthermore, the interaction between Firm Size and Auditor Switching is positive and significant (B = 0.998, p = 0.001), suggesting that auditor switching strengthens the positive association between Firm Size and KAM disclosure.
