State Auto Financial Corporation (NASDAQ: STFC) today reported a first quarter 2009 net loss of $14.0 million, or $0.35 per diluted share, versus net loss of $12.5 million, or $0.31 per diluted share, for the first quarter of 2008. Net loss from operations* per diluted share for the first quarter 2009 was $0.18, versus net loss of $0.28 for the same 2008 period.

STFC�s GAAP combined ratio for the quarter was 112.0 versus 111.3 for the first quarter of 2008. Catastrophe losses accounted for 15.3 points of the total 78.6 loss ratio points, or $43.8 million, during the first quarter this year, compared to 12.5 points of the total 76.8 loss ratio points, or $35.0 million, for the same period in 2008. Net written premium for the quarter increased 5.7% over the same period in 2008. STFC�s book value was $19.21 per share as of March 31, 2009, a decrease of $0.02 per share from STFC�s book value on December 31, 2008. Return on stockholders� equity for the twelve months ended March 31, 2009 was negative 4.0% compared to positive 8.7% for the twelve months ended March 31, 2008.

�The unusual run of catastrophic storms continued for State Auto into 2009, producing unprecedented first quarter losses. As reported earlier, most of the damage was done by ice and wind storms that hit in late January and early February,� said STFC Chairman, President and CEO Bob Restrepo.

�STFC�s production for the quarter was strong. Overall net written premium grew 5.7%, driven by standard private passenger auto which grew 14.2%. Our new products and advanced technology have strengthened our position with our independent agency partners and allowed us to take advantage of increased consumer shopping. Growth is also driven by our entry into and development of new states via expansion and acquisition.

�We are pleased with the non-CAT underwriting results in our core book. STFC�s loss ratios are on plan in this highly competitive market. In particular our business insurance results were profitable despite a significant large fire loss in the Columbus area. We are taking actions to further mitigate the impact of catastrophe losses, including the adoption of an aggregate reinsurance treaty, pricing and deductible changes for wind and hail coverage, and the development of agency management practices that address geographic concentrations,� added Restrepo.
