The country's leading private sector lender - Kotak Mahindra Bank - on Friday reported net profit of Rs 2,131 crore in quarter ended December 2021, marking an increase of 15 per cent from 1,853.54 crore during the same period last year. The uptick in profit came on the back of sharp reversal in provisioning for bad loans as it wrote back provisions worth Rs 132 crore during the quarter compared with provisioning of Rs 424 crore in the September quarter.
