The Association between Audit Quality and Earnings Management by Listed Firms in Nigeria (Published)
This study examines the association between audit quality and earnings management by listed firms in Nigeria. The study measures audit quality by audit firm size and earnings management by the absolute abnormal discretionary accruals using the modified Jones model. The study was carried out in two parts, the first part is the comparative study using independent sample t-test and the Wilcoxon signed ranked test. The second part is the multivariate analysis where the association between audit quality and earnings management was examined. Based on our analysis, we found that auditor size has restrained earnings management but the decrease is not statistically significant. The implication of this finding is that users should not blindly assume that high audit quality proxy by the big 4 auditor is a symbol of earnings quality.

This paper investigates the differences in the quality of accounting information Pre and post IFRS adoption by manufacturing firms in Nigeria over a five year period. Multiple regression analysis was performed on accounting quality variables and t-test was carried out for equality of mean to compare pre and post IFRS.

Earnings and book value of equity are less value relevant and timely loss recognition is less in post-IFRS compared to pre-IFRS period
THE EFFECTS OF CHANGES IN ACCOUNTING STANDARDS ON EARNINGS MANAGEMENT OF MALAYSIA AND NIGERIA BANKS (Published)
: The objective of this study is to investigate the effects of changes from Malaysia and Nigeria previous accounting standards to IFRSs-based standards on earnings management of Malaysia and Nigeria banks. Limited studies on the association between IFRS and earnings management in emerging economies and the continuous exclusion of financial institutions from samples of prior studies motivated this study to acquire the banking sector of two emerging countries – Malaysia and Nigeria in order to investigate whether changes in Malaysia and Nigeria accounting standards affects earnings management activities. Hence, this study used a sample of 23 banks representing 8 Malaysian banks and 15 Nigerian banks for a study period of 4 years (2009-2012). This study modified the Jones (1991) model to investigate earnings management in the banking sector. The modified Jones model is able to investigate earnings management in the banking sector. MFRSs and IFRSs impact more significantly and positively on the quality of accounting information of banks than the previous FRSs and SASs respectively for Malaysia and Nigeria. Specifically, the accrual and earnings quality of Nigerian banks has improved by approximately 41% and Malaysia banks 12.6% during the IFRSs/MFRSs adoption era. This study therefore recommends that globally, IFRSs should be adopted as the standard for the preparation and reporting of financial statements
This study follows prior studies on cash – based activities manipulations to investigate total levels of cash – based earnings management relative to the association between cash – based earnings management and audit firm size of companies in Nigeria. First, the study measures the normal level of real activities by focusing on three manipulation schemes namely, manipulation of sales, overproduction, and reduction in discretionary expenses. The normal levels of each type of real activities manipulation were measured as the residual from relevant estimation models. The abnormal CFO, abnormal production costs and abnormal discretionary expenses were computed as the difference between the actual values and the normal levels predicted from the respective models while the composite value of the three variables is the estimate for cash – based earnings management. Based on a sample of 342 companies – year observations from the NSE and applying audit firm size as a measure, comprehensive multivariate analyses were conducted on archival data covering 2006 – 2011. The result showed that audit firm size exerts significant negative relationship with cash – based earnings management of quoted companies in Nigeria. It is suggested that companies in Nigeria should improve their earnings quality only through sales growth and cost control strategies and present distinct reports on earnings quality; company auditors should issue Integrated Audit Quality Assurance Reports based on earnings quality assessments statutorily backed by earnings monitoring of companies in Nigeria; while regulatory agencies should issue authoritative codes of best practice in Nigeria
AUDITOR TENURE, AUDITOR INDEPENDENCE AND ACCRUAL – BASED EARNINGS MANAGEMENT OF QUOTED COMPANIES IN NIGERIA (Published)
Auditor Tenure defines the length of the auditor-client relationship while auditor independence (measured by the quantum of audit fees received) defines an auditor’s quality of being free from influence, persuasion or bias, and hence the unbiased mental attitude in making decisions throughout the audit and financial reporting process. The absence of independence may greatly impair the value of the audit service and the audit report. On the other hand, an excessively long association between the auditor and his client may constitute a threat to independence. This study examines the relationship and effects of auditor tenure and auditor independence on the earnings management (measured by the amount of discretionary accruals) of companies in Nigeria. The study relies on secondary data derived from various companies’ financial statements and the Nigerian Stock Exchange fact book to determine and measure the level of earnings manipulations in corporate financial statements, applying an all-inclusive multivariate analysis. The empirical analysis using a total of 342 company year observations, shows that Audit tenure and auditor independence exert significant effects and exhibit significant relationship with the amount of discretionary accruals of quoted companies in Nigeria. The descriptive statistics result reveals a minimal presence of discretionary accrual management by the companies in the sample and on the average; about 94% of the companies engage their audit firms for over three years, with a considerable experience of a substantial number of audit firms in this distribution
