The Montreal-based company will start accepting credit cards across all of its stores this year, the retailer said on Thursday, as it posted stronger-than-expected results that sent its stock surging. It earned $146.1 million or $1.24 per diluted share for the quarter ended Jan. 29, up from $124.8 million or $1.00 per diluted share a year earlier. Sales for what was the company’s fourth quarter improved to $854.5 million compared with $766.5 million in the same quarter a year ago.

TD Bank has enlisted the help of an outside company to review its business in light of reports that some employees allegedly broke the law in order to meet sales targets and keep their jobs. “It’s not an unusual event in the bank that we ask outside firms to come and assist us,” CEO Bharat Masrani told reporters following the bank’s annual shareholder meeting Thursday.
