State Auto Financial reports fourth quarter and year 2012 results

Columbus, Ohio (February 19, 2013) – State Auto Financial Corporation (Nasdaq:STFC) today reported fourth quarter 2012 net income of $20.9 million, or $0.51 per diluted share, versus net income of $99.3 million¹, or $2.46 per diluted share¹, for the fourth quarter of 2011. Net income from operations² per diluted share for the fourth quarter 2012 was $0.38 versus net income from operations² of $2.27 for the same 2011 period¹. Net income for the fourth quarter of 2011 included a $14.9 million postretirement benefit curtailment gain and $35.7 million of federal income tax benefit.

STFC’s GAAP combined ratio for the fourth quarter 2012 was 101.7 versus 94.3¹ for the fourth quarter of 2011. Catastrophe losses during the fourth quarter 2012 accounted for 2.2 points of the 68.7 total loss ratio points, or $5.9 million, versus a favorable impact of 0.5 points of the total 59.7 loss ratio points, or $1.8 million, for the same period in 2011.

The State Auto Group’s homeowners quota share reinsurance arrangement increased STFC’s underwriting loss by $12.5 million or 4.2 points on the combined ratio for the fourth quarter of 2012. Pursuant to the arrangement, STFC ceded $40.9 million of written premium, $40.4 million of earned premium, $2.0 million of catastrophe losses and $14.2 million of non-catastrophe losses, and recognized $11.7 million of ceded commissions. This cession decreased STFC’s overall catastrophe loss ratio 0.4 points, increased the overall non-catastrophe loss ratio 4.1 points and increased the overall expense ratio 0.5 points.

Net written premium for the fourth quarter of 2012 increased 76.7% over the same period in 2011. The homeowners’ quota share reinsurance arrangement and the 2011 year-end pooling change collectively contributed to this increase, as the ceded unearned premium reserve amounts transferred under these two arrangements were reflected as reductions to net written premium in the prior year’s results. By segment, net written premium for the fourth quarter of 2012 increased 207.2% for personal insurance, 64.5% for business insurance and 0.5% for specialty insurance from the same period in 2011. Excluding the impact of the quota share reinsurance arrangement and pooling change, net written premium for the fourth quarter of 2012 increased 2.2%³ from the same period in 2011, with the business insurance segment contributing primarily to the overall growth. The business segment growth was principally driven by higher average new business premium, increased renewal pricing and a recovering economy. Excluding the impact of the homeowners’ quota share and pooling change, net written premium for the fourth quarter increased 2.3%³ for the personal insurance segment, increased 20.8%³ for the business insurance segment and decreased 17.6%³ for the specialty insurance segment from the same period in 2011. The decline in our specialty segment was due to the termination of substantially all of the business written by the former management team of RED. As previously disclosed, we have reorganized and merged the operations of RED into the Rockhill unit’s program division.

For the year 2012, STFC had net income of $10.7 million, or $0.27 per diluted share, compared to a loss of $160.7 million¹, or $4.00 per diluted share¹, for the same 2011 period. STFC’s GAAP combined ratio for 2012 was 107.9 compared to 116.5¹ for the same 2011 period. Catastrophe losses accounted for 6.4 points, or $67.1 million, during 2012, compared to 16.2 points, or $231.1 million, during 2011. The 2012 and 2011 catastrophe losses both included favorable prior accident years’ development which reduced the loss ratio by 1.0 points, or $10.4 million for 2012, and 0.3 points, or $4.3 million for 2011. Non-catastrophe favorable reserve development reduced the loss ratio by 0.6 points, or $6.5 million for 2012, and 2.0 points, or $29.0 million for 2011.

For the year 2012, the homeowners quota share reinsurance arrangement reduced STFC’s underwriting loss by $6.0 million and added 0.7 points on the combined ratio. Pursuant to the arrangement, STFC ceded $172.3 million of written premium, $166.2 million of earned premium, $49.5 million of catastrophe losses and $74.5 million of non-catastrophe losses, and recognized $48.2 million of ceded commissions. This cession reduced STFC’s overall catastrophe loss ratio 3.2 points, increased the overall non-catastrophe loss ratio 3.3 points and increased the overall expense ratio 0.6 points.

Net written premium for year 2012 decreased 17.8% compared to the same 2011 period. The homeowners’ quota share reinsurance arrangement and the 2011 year-end pooling change contributed to the decrease. For the year 2012, net written premium decreased 27.5% for the personal insurance segment, increased 2.3% for the business insurance segment and decreased 20.0% for the specialty insurance segment from the same period in 2011. Excluding the impact of the quota share reinsurance arrangement and pooling change, net written premium for the year 2012 decreased 0.9%³ for the personal insurance segment while business and specialty insurance increased 14.0%³ and 0.5%³, respectively from the same period in 2011.

STFC’s book value was $18.22 per share as of Dec. 31, 2012, a decrease of $0.08 per share from STFC’s book value on Sept. 30, 2012. Book value per share as of Dec. 31, 2012, included a reduction of $2.48 for a deferred tax asset valuation allowance. Return on stockholders’ equity for the twelve months ended Dec. 31, 2012, was 1.5% compared to negative 20.7%¹ for the twelve months ended Dec. 31, 2011.

STFC President, Chairman and CEO Bob Restrepo commented on the quarter as follows:

“State Auto Financial Corporation finished 2012 with positive net income for the quarter and year. Fundamentals in our core business are improving led by better ex-catastrophe loss ratios. As the final RED programs terminate, we made a decision to add an additional $7.2 million to our reserves in the fourth quarter for prior accident years, primarily relating to a sizeable restaurant program. Our view of the trucking program has not materially changed since the end of the third quarter.

“RED contributed 6.3 combined ratio points in our fourth quarter and 5.6 points for the year. We incurred $7.3 million in losses from Superstorm Sandy causing a modest increase in catastrophe losses for the fourth quarter, net of prior quarter reserve reductions.

“Personal auto loss ratio improved for the year due to better weather and lower catastrophe losses. Bodily injury severity remains high and we’re responding with price increases. We’re pleased with progress made in our traditionally unprofitable homeowners line. Our pricing, underwriting, reinsurance and agency management actions are paying off. Our full year non-CAT loss and ALAE ratio was below 40%, the best result in over five years. We continued to implement aggressive actions which resulted in a price impact of more than 20% in 2012, with similar expectations in 2013. We believe these actions will contribute to turning around this difficult line.

“Excluding RED, commercial lines profitability and growth were strong for the quarter and year. In standard commercial lines, prices increased 5.0% for the quarter and 3.5% for the year. Our month-over-month price increases are strong and we plan for high-single digit increases in 2013. Ex-catastrophe loss ratios improved for the quarter and year – the best loss ratios since 2009 with substantial improvement over 2011. In our specialty segment, Rockhill finished with exceptionally strong profit and production. Workers compensation also improved in the quarter led by our RTW subsidiary.

“We’re pleased with improving fundamentals demonstrated by improving ex-catastrophe loss and expense ratios. We enter 2013 with positive momentum and expect continuing underwriting improvement, growth and increased book value. We’re making solid progress towards achieving our goal of a double digit return on equity.”
