Purpose-This study examines the effect of ownership structure on corporate tax aggressive activities of listed firms in Nigeria. Methodology-Data were extracted from the annual reports of 40 non-financial firms that made up the sample of the study from 2010 to 2014. The effects of ownership concentration and managerial ownership as independent variables on tax aggressiveness as the dependent variable were observed in S fixed effect model including those of the control variables. Findings-The study reveals that ownership concentration has a positive but insignificant effect on tax aggressiveness while the effect of managerial ownership was found to be significantly negative. Further results show that leverage is negatively related with tax aggressiveness while return on assets is positively related. Size has not significant relation with tax aggressiveness Conclusion-In the Nigeria context, only managerial ownership type of ownership structure determines how tax aggressive a firm is.

This study examines the Corporate Effective Tax Rates (ETRs) of non-financial firms listed in NigerianStock Exchange. The study also measures the neutrality of taxation within the Nigerian economic sectors and establishes the relationships between ETRs and firm specific characteristics of size, leverage, profitability, capital intensity, inventory intensity, labour intensity and auditor type. Data were extracted from the financial statements of sampled firms in respect of the variables and subjected to analyses in ordinary least square (OLS), random effect and fixed effect models. The results show that ETRs were lower than the Statutory Tax Rate during the period of the study and that there are differences in ETR from one sector of the economy to the other. The study further reveals that larger and more profitable firms are faced with high tax burden while firms with high leverage, capital intensity, and tax expert (auditor type) are faced with lower ETR. There is no significant relationship between ETR and labour intensity.

Enterprise Risk Management (ERM) is an integrated framework and monitoring tool for managing uncertainties surrounding the business objectives. This study evaluated the relationship between enterprise risk management and performance of Twenty (20) consumer goods companies listed on the Nigerian Stock Exchange. The independent variables used are existence of risk management committee, existence of financial expertise, existence of audit committee, existence of Chief risk officer and board size. The study adopted ex post facto research design and data were sourced from annual reports and accounts of the selected Consumer Goods Companies. The collated data were analysed using descriptive statistics and generalised least square. The results reveal that risk management committee, financial expertise and board size have significant positive effect on performance. The results also revealed that existence of audit committee has a significant negative effect on performance while existence of chief risk officer has no significant effect on performance. The study therefore recommended that the regulatory authorities and other relevant institutions are enjoined to reassess their supervisory role with the view to strengthen the ERM process and taking the issue of risk management seriously at every level of organisations to provide reasonable assurance.

This study examines the effect of the 2007 reform pertaining to the corporate tax system on the tax burden of listed firms in Nigeria using the t-test and canonical correlation analysis. Data were collected from the financial statements of the 86 sampled firms for the period 2003-2011 subdivided into pre-reform (2003)(2004)(2005)(2006) and post reform (2008-2011) sub-periods for the purpose of comparing periods' tax burdens. Data were also segregated along the Nigerian Stock Exchange industrial sector classifications. This study finds, on the whole, that the 2007 corporate tax reform has brought minimal tax burden on listed firms, however, sectoral analysis reveals the heterogeneity in the effect of the tax reform as firms within the agricultural and natural resources sectors witnessed increases in tax burden while firms in health and oil and gas sectors were favoured with reduced tax burden. The tax burden of other sectors is unaffected by the reform.
