Virginus Ph.D, Nwakoby, N. Peace Ph.D Abstract: We carried out this empirical study: implementation of ISA 710- Key Audit Matters KAMs in Nigeria. The methodology utilized a pooled data research design. These are data with both cross section and time interval. We applied data sourced from annual reports of firms quoted in the Nigerian Stock Exchange (NSE). Population comprised all the quoted firms on the NSE from 2017-2020 and a purposive sample size of (30) firms that have evidence of disclosure of KAMs within these period. We apply Descriptive Statistics, Correlation and Multiple Regressions to determine the impact that firm age, firm leverage, and audit gender have on KAMs. Our empirical evidences show that about 44% of the systematic variations in the dependent variable in the pooled companies over the period in Nigeria are jointly explained by the independent variables of KAMs; while our specific findings show that Audit gender has a negative and insignificant impact on implementation of KAMs; Firm age and leverage have a positive significant impact on implementation of KAMs. We recommend that implementation of KAMs have cumulative impact and that only leverage and Firm age contribute positively. We, contributes with the evidence of variables that have impact on KAMs implementations in Nigeria; the rich literature and the relevance of the content of the applied model of KAMs.
