The findings of the study  revealed that the three models to exhibited results, each model reflects and reported its efficiency score categories and the author conclude from the empirical literature that the all the three models do exhibit different efficiency score. Furthermore the study noted that the banks within the peer group were operating at higher level of efficiency but the industry at large still operates at inefficiency level but operate at higher level of profit efficiency due higher level of interest spread, large banks have been more efficient then the medium banks followed by the Non-Banking Financial institutions and finally the medium banks.
