The primary purpose of every business firm is to make a profit which is the economic performance in the Triple Bottom Line. However, a social and environmental performance which is Corporate Social Responsibility (CSR) has been argued to be very crucial for firms' sustainability. This argument has drawn the attention of researchers across the globe to various empirical studies which have produced confounding results. This study provides new evidence from Nigeria by disaggregating CSR into Community Development, Education and Health, and finding their effect on performance which is proxied by Return on Assets. The data were extracted from the audited annual reports of 12 Deposit Money Banks listed on Nigeria Stock Exchange for ten years, 2009-2008. The study found out that CSR on Community Developments has a positive and significant effect on financial performance. On the contrary, the study reveals that CSR on Education has an insignificant positive effect on financial performance, and CSR on Health has a negligible negative effect. The study recommends that management of Deposit money banks in Nigeria should not blindly engage in CSR activities, but should selectively select the CSR activities that can take care of all the stakeholders’ interest.
