“State Auto’s second quarter results are traditionally hurt by weather, both catastrophic and non-catastrophic. This year was no exception with significantly higher levels of wind and hail losses, particularly in the northern Midwest. Approximately 60% of storm losses were reported in four of our largest property states: Indiana, Minnesota, Ohio and Tennessee. In addition to wind and hail, the Nashville area suffered a thousand year storm and unprecedented flooding. Although flood is not a covered peril for homeowners, it is for commercial property and automobile insurance. In addition, the heavy rain produced numerous claims for leaky roofs and water damage. All in all, it was a difficult quarter weather wise for State Auto, our policyholders and for the industry,” said STFC Chairman, President and CEO Bob Restrepo.

“Catastrophe results masked continued improvement in our non-catastrophe loss ratio driven by personal lines. In particular, we continue to see substantial improvement in our personal automobile experience, even with an increase in claims resulting from the Nashville flooding. Large loss activity returned to normal levels in both homeowners and commercial property, but increased in the general liability line.

“Operating results, along with changes to our pension plan and investment valuations, contributed to a decline in our book value per share.

“Both personal and business insurance contributed to our strong overall premium growth in the quarter. Personal insurance premium growth resulted from continued price increases, stable retention, and strong, although lower, new business production. Our new affiliate in the alternative risk transfer market, Risk Evaluation and Design, LLC (RED), accounted for virtually all of our premium growth in business insurance. Production in our standard business insurance lines has stabilized. Policy retention is better than expected, but the economy and pricing environment have constrained new business production.

“In June, we completed the final phase of our BOP Choice rollout. BOP Choice gives us improved pricing precision and the ability to attract more casualty oriented business. This product has been well received by our agents and, we believe, will contribute to more stable profit and production results in the future.

“The restructuring of our field underwriting, sales and claim operations is substantially complete. We believe our cost structures for personal lines and claims are now very competitive, but more work needs to be done in our business insurance segment. Productivity levels remain low relative to the industry and integrating our specialty business may increase our expenses in the short term. We’ll need to streamline workflows and introduce new technology to improve productivity and maintain service levels. Over the long term, the actions we’re taking should pay off with a more balanced book of business and better underwriting results.”
