Updated from 9:42 a.m. EDTFirst Data Corp. ( FDC) Thursday reported higher first-quarter results, though much of the gain was credited to the sale of its ATM unit. The company posted net income of $483.5 million, or 61 cents a share, including discontinued operations, for the three-month period ended March 31, up from $292.6 million, or 39 cents a share, in the year-ago period. Revenue rose to $2.26 billion, from $1.97 billion in the year-ago period. Analysts' consensus estimate was for 44 cents a share, according to Thomson First Call. The $436 million sale of Global Cash Access, the nation's largest network of ATMs in casinos, accounted for a gain of 21 cents a share. The Denver-based credit card transaction-processing company, and parent of Western Union, also reported a non-cash 2 cents-a-share restructuring charge related to accounting problems found at its TeleCheck business in 2002 and 2003. The company is reviewing TeleCheck's "strategic fit," it said in a statement. First Data shares were recently up 3.7% to $46.45.
