Credit risk disclosures in financial firms are contingent upon corporate governance. For all financial firms that lend to individuals and legal entities, the issue of managing credit risk and conducting a quantitative evaluation and analysis of borrowers' credit risk and rating are pertinent. This study looks into how financial firms' disclosure of credit risk is affected by corporate governance. It looks into the relationship between credit risk disclosure and nonperforming loans, board size, and board makeup. The study's research design is ex-factor. Data came from financial firms' annual disclosures on the Nigeria Stock Exchange. To examine the data, SPSS was used. Multiple regressions were used to formulate the tested hypotheses. According to the regression analysis, there is a significant and negative correlation between the size of the board of directors and the coefficient. This finding implies that a larger board lowers the percentage of nonperforming loans. Additionally, the study reveals that non-performing loans—a proxy for corporate governance—are negatively and statistically insignificantly impacted by board composition. As a result, the study suggests that financial institutions improve the performance of nonperforming loans and give careful consideration to financial literacy when choosing board members
