Profit attributable to common stock rose to $692 million, or 47 cents per share, in the three months ended March 31, from $228 million, or 16 cents a share, a year earlier.Revenue rose to $4.87 billion from $3.34 billion. Excluding one-time charges, the profit was 46 cents per share, while analysts on average had expected 56 cents, according to Thomson Reuters.
