Big 4 auditors, bank earnings management and financial crisis in Africa

Purpose This paper aims to examine whether African banks audited by a Big 4 auditor use loan loss provisions (LLPs) for earnings management purposes before, during and after the global financial crisis. It focuses on income smoothing as a type of earnings management. Design/methodology/approach The study analyzed banks in 21 African countries from 2002 to 2014. The estimation techniques used are the fixed effect regression technique, descriptive statistic and Pearson correlation statistic. The model used in the study expresses LLPs as a function of its discretionary and non-discretionary determinants. Findings African banks audited by Big 4 auditors use LLPs to smooth income and the incentive to smooth income is greater during an economic downturn or recession. Also, African banks audited by a Big 4 auditor use income smoothing to lower high earnings during the financial crisis and in the pre-financial crisis period but not in the post-financial crisis period. Originality/value The literature shows that the presence of Big 4 auditors improves earnings quality. The direct impact of Big 4 auditors on earnings management in African banks has received little attention in the literature, and the impact of audit quality on bank earnings smoothing particularly in Africa is yet to be known.
