The purpose of this work is to examine the interaction of members of the board with financial knowledge on the association among capital structure with firm financial performance in the Nigeria DMBs. Empirical studies were reviewed to scrutinize the upshot of capital structure in connection to the performance of firms. As the result of the foregoing, this study introduces board financial literacy as a moderator variable to interact between capital structure with performance of firms. A correlational design was adopted. Population and sample size of the study consists of 13 listed DMBs on the floor of Nigeria Stock Exchange for the period 2012 to 2021. Fixed effects regression model was employed to analyse the data of the study. Diagnostic test was conducted to confirm the validity of the statistical inferences of the study. The result shows that BFL moderated the correlation involving DEFR with financial performance. Also, the result found that EFR and DEFR were not significant to the firm financial performance of DMBs in Nigeria. This work recommends that board members with financial literacy should come up with effective policy towards encouraging debt financing in their entities by effective supervision so as to enhance the overall firms’ financial performance as well as safeguarding shareholders interest. Research in future should replicate this topic in a domain other than DMBs.

There is limited evidence about the association between audit committee (AC) characteristics and effective whistleblowing policy. In light of the above, this study explores the relationship between AC and the effective whistle-blowing policy in Nigerian Banks. The study uses a period of ten years (2009 to 2019). It employs a logistic regression technique in the analysis. Data for the study were found from the listed banks’ yearly reports. The results revealed that firms that have AC composed of independent directors, have more financial experts, and meet regularly are more likely to have an effective whistleblowing policy. Moreover, a larger AC is associated with a weak whistleblowing policy. Therefore, it is recommended that regulators such as the Security and Exchange Commission (SEC) and the Nigerian Central Bank (CBN) should ensure stringent compliance of their codes of corporate governance on AC composition as both of them recommend the existence of autonomous directors and financial experts in the AC. However, the findings and recommendations are only applicable to listed banks in Nigeria. For this reason, further research may be needed to be conducted on the AC attributes in other sectors like manufacturing firms.
