Abstract

The study examined how quality of audit impacted on income smoothing practice among listed Nigerian Deposit Money Banks (DMBs). While audit quality (AQ) was represented by audit fees (AF), audit firm size (AFS) and audit tenure (AT), income smoothing (IS) was represented by binary variable obtained from the Eckel index of income smoothing. Data were obtained from eleven (11) listed banks from 2013 to 2021. Binary logistic regression was employed. The results indicated that AF is positively associated with IS (β=2.23; p<0.05). In addition, the impact of AFS represented by big 4 on income smoothing was negative (β=-3.014; p<0.05), while that of audit tenure was positive but not significant (β=0.047; p>0.05). The results were similar when the accrual measure of income smoothing was used. The study concluded that the quality of audits determines the tendency for income smoothing among Nigerian listed banks. It is therefore recommended that regulators and the management of listed DMBs in Nigeria emphasize and employ the services of large reputable audit firms (BIG 4), as it appears to be negatively related to income smoothing. In addition, auditors should be well remunerated in order to ensure that they exert significant effort to mitigate the incidence of income smoothing.
