State Auto Financial reports third quarter 2012 results

Columbus, Ohio (November 6, 2012) – State Auto Financial Corporation (Nasdaq:STFC) today reported a third quarter 2012 net loss of $5.5 million, or $0.14 per diluted share, versus a net loss of $58.7 million⁽¹⁾, or $1.46 per diluted share⁽¹⁾, for the third quarter of 2011. Net loss from operations⁽²⁾ per diluted share for the third quarter 2012 was $0.25 versus net loss from operations⁽²⁾ of $1.62 for the same 2011 period⁽¹⁾.

STFC’s GAAP combined ratio for the third quarter 2012 was 110.2 versus 122.41 for the third quarter of 2011. Catastrophe losses, net of reinsurance recoveries, for the third quarter 2012 accounted for 2.8 points of the 77.1 total loss ratio points, or $7.2 million, versus 17.0 points of the total 88.4 loss ratio points, or $60.8 million, for the same period in 2011. Non-catastrophe losses included $19.5 million of loss and loss expense reserve increases for prior periods on program business written by Risk Evaluation & Design LLC (RED), a wholly owned subsidiary of State Automobile Mutual Insurance Company. The reserve increases related primarily to a large commercial auto trucking program that, as previously disclosed, was cancelled as of April 1, 2012.

The State Auto Group’s homeowners quota share reinsurance arrangement increased STFC’s underwriting loss by $13.1 million or 5.8 points on the combined ratio. Pursuant to the arrangement, STFC ceded $47.5 million of written premium, $42.4 million of earned premium, $0.1 million of catastrophe losses and $17.0 million of non-catastrophe losses, and recognized $12.2 million of ceded commissions. This cession increased STFC’s overall catastrophe loss ratio 0.4 points, increased the overall non-catastrophe loss ratio 4.8 points and increased the overall expense ratio 0.6 points.

Net written premium for the third quarter of 2012 decreased 29.1% over the same period in 2011. The homeowners’ quota share reinsurance arrangement and the year-end pooling change collectively contributed the entire amount of this decline. By segment, net written premium for the third quarter of 2012 decreased 42.2% for personal insurance, increased 0.5% for business insurance and decreased 29.0% 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 third quarter of 2012 increased 2.9%⁽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. Additionally, business segment net written premium includes $7.2 million of unearned premium transferred from terminating an umbrella quota share reinsurance arrangement effective July 1, 2012. Excluding the impact of the homeowners’ quota share and pooling change, net written premium for the third quarter decreased 0.8%⁽³⁾ for the personal insurance segment, increased 23.7%⁽³⁾ for the business insurance segment and decreased 12.6%⁽³⁾ for the specialty insurance segment from the same period in 2011.

For the first nine months of 2012, STFC had a net loss of $10.2 million, or $0.25 per diluted share, compared to a loss of $260.0 million⁽¹⁾, or $6.47 per diluted share⁽¹⁾, for the same 2011 period. STFC’s GAAP combined ratio for the first nine months of 2012 was 110.0 compared to 124.3⁽¹⁾ for the same 2011 period. Catastrophe losses increased the loss ratio for the first nine months of 2012 by 7.9 points, or $61.2 million, compared to 22.0 points, or $232.9 million for the first nine months of 2011.

For the first nine months of 2012, the homeowners quota share reinsurance arrangement reduced STFC’s underwriting loss by $18.5 million or 0.7 points on the combined ratio. Pursuant to the arrangement, STFC ceded $131.4 million of written premium, $125.9 million of earned premium, $47.5 million of catastrophe losses and $60.4 million of non-catastrophe losses, and recognized $36.5 million of ceded commissions. This cession reduced STFC’s overall catastrophe loss ratio 4.2 points, increased the overall non-catastrophe loss ratio 2.9 points and increased the overall expense ratio 0.6 points.

Net written premium year to date 2012 decreased 29.9% compared to the same 2011 period. The homeowners’ quota share reinsurance arrangement and the year-end pooling change contributed to the decrease, but were offset by growth in the business and specialty segments. For the first nine months of 2012, net written premium for the personal, business and specialty insurance segments declined 41.8%, 9.0%, and 24.8% respectively, compared to the same period in 2011. Excluding the impact of the quota share reinsurance arrangement and pooling change, net written premium for the first nine months of 2012 decreased 1.9%⁽³⁾ for the personal insurance segment while business and specialty insurance increased 12.0%, and 7.9%, respectively from the same period in 2011.

STFC’s book value was $18.30 per share as of Sept. 30, 2012, an increase of $0.48 per share from STFC’s book value on June 30, 2012. Book value per share as of Sept. 30, 2012, included a reduction of $2.45 for a deferred tax asset valuation allowance. Return on stockholders’ equity for the twelve months ended Sept. 30, 2012, was 13.6% compared to negative 31.8% for the twelve months ended Sept. 30, 2011. The 13.6% return on stockholders’ equity includes, in the fourth quarter of 2011, a $35.7 million tax benefit recorded as a result of intra-period tax allocations and a $14.9 million postretirement benefit curtailment gain.

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

“Third quarter results were helped by significantly better weather, continued improvements in our ex-catastrophe loss ratio performance for our personal, business and specialty insurance segments, and an improving pricing environment. These positive developments were offset by the previously announced reserve adjustment for the RED business now in run-off. Investment income is also down as interest rates and fixed income returns remain at historically low levels. While we’re very disappointed in the RED performance, we have confidence that the actions we’ve taken will eliminate a drag on our financial performance.

“Results in property lines, both homeowners and commercial property, were exceptional in the quarter. We benefitted from a lack of catastrophes and increasing prices. Performance in personal and commercial auto was relatively unchanged, but we’re now charging higher prices in excess of loss trends and anticipate expanding margins in what are traditionally our most profitable lines. Liability lines also improved as our changes to the claim process are beginning to pay off. In our specialty segment, our Rockhill and RTW subsidiaries are producing solid underwriting profits and good growth. These specialty businesses will be important contributors to diversifying our source of future earnings and achieving greater scale in the commercial lines market place.”
