Mortgage lender Housing Development Finance Corporation (HDFC) on Monday reported a 233% year-on-year (y-o-y) jump in its standalone net profit for the December quarter at Rs 5,670.21 crore, driven largely by a one-time gain of Rs 3,675.31 crore from the sale of its stake in HDFC Standard Life Insurance Company. Adjusted for the one-time gain, the company’s performance exceeded expectations of analysts, based on Bloomberg collated data. HDFC’s net interest income (NII) for the quarter came in at Rs 2,929 crore against Rs 2,575 crore in the same quarter last year, a rise of 14%.
