IntroductionIn recent times, the call for reliable financial reporting has gained prominence in Nigeria and global economy at large. The capability or incapability of banks to effectively fulfill intermediate mandate has been the crux of many financial crises. Mediating between the surplus and deficit units within the economy expedites distribution of national savings, thereby improving investments and national output. In 2005, the Central Bank of Nigeria mandated every Nigerian bank to increase capital base from 2 billion naira to 25 Billion Naira in order to enhance competitiveness in the international market.
