Discover chairman and chief executive officer David Nelms said the firm’s results for this quarter represents a great start for 2012.

"Continued improvements in credit performance, solid organic growth in each of our lending products and strong volume growth across our networks were key drivers of this quarter’s earnings," Nelms said.

The company’s direct banking pretax income was $962m in the quarter up $285 million, or 42%, from the previous year.

Discover card sales volume rose 7% from the prior year to $25.6bn, primarily driven by an increase in the number of customers using their Discover card.

Net interest income grew $123m, or 11%, from the prior year, primarily driven by an increase in income from student and personal loans and lower interest expense.
