The total revenues for the first quarter of 2012 increased 2% to $6.39bn, compared to $6.27bn for the same period a year ago.

Operating income decreased 3% to $801m, compared to $826m for the same period prior year.

Net written premiums increased 1% to $5.49bn, compared to $5.43bn in the prior year quarter.

Travelers chairman and CEO Jay Fishman said that the company’s underwriting performance reflected a GAAP combined ratio of 92.2%, an improvement of 2.5 points from the prior year quarter and 3.7 points from fourth quarter 2011.

"Net investment income, while down modestly from the prior year quarter as a result of continuing low fixed reinvestment yields, remained strong,"Fishman said.
