Private sector lender Yes Bank on Friday reported an increase of 25 per cent in net profit at Rs 675.74 crore in the December quarter, driven by higher interest income even though its bad loans jumped sharply following a regulatory review of top stressed accounts. The city-based bank said the sharp rise in bad loans was due to RBI review of top accounts which saw its net NPAs doubling to 0.22 per cent in the quarter under review, as against 0.1 per cent an year ago. Due to sharp increase in NPAs, its provisioning for bad loans grew over two-fold to Rs 187.2 crore during the quarter, while gross NPAs jumped to 0.66 per cent or Rs 558.6 crore from 0.42 per cent an year ago.
