May 5 (Reuters) - Health insurer Cigna Corp reported a 15 percent rise in quarterly profit, helped by customer growth in its commercial business.
The company's net income rose to $598 million, or $2.30 per share, in the first quarter ended March 31, from $519 million, or $2.00 per share, a year earlier.
Total revenue increased to $10.39 billion from $9.88 billion.
