Cincinnati, June 14, 2010 - Cincinnati Financial Corporation (Nasdaq: CINF) today said that as of June 10, 2010, it estimates incurred second-quarter pre-tax catastrophe losses from severe weather at approximately $65 million for its property casualty insurance operations through The Cincinnati Insurance Companies. Catastrophe losses affect property casualty insurance underwriting income, one of the sources of consolidated net income along with profits from investment operations and life insurance operations.

Kenneth W. Stecher, president and chief executive officer, commented, "Our storm losses typically rise in the second quarter, averaging 7.7 percentage points over the past 10 years compared with a full-year average of 4.2 percentage points. If no additional catastrophe losses are incurred beyond those we estimated through June 10, our 2010 second-quarter estimate would stand at approximately 9 percentage points, bringing our early estimate for the first half to approximately 5.6 percentage points. Catastrophe losses can vary significantly from quarter to quarter, as shown by our below-average contribution of only 2.1 percentage points in the first quarter of 2010.

"Our agents and policyholders know they can depend on Cincinnati Insurance to provide the highest quality service for claims involving storms or other insured loss events. A total of eight events, including a storm in June that primarily affected our policyholders in northern Ohio, together accounted for approximately half of our policyholders' estimated second-quarter catastrophe losses. The other half was largely due to claims in Nashville, Tennessee for water-damaged business equipment and related business interruption. Policyholders can purchase all-risk coverage for some types of equipment and expanded coverage for business interruption as options with our commercial multi-peril policy."

Representatives of Cincinnati Financial Corporation management will review progress on strategic initiatives for improving profitability and driving premium growth at the Macquarie Small & Mid-Cap conference on June 15, 2010, as previously announced. Stecher concluded, "We continue during the second quarter to execute on these initiatives, including preparations for entry to two new states outside of our Midwest footprint, increased pricing precision and introduction of our Educational Institutions Program - the first product release from our new target markets unit. In May, we received the Vanguards in Insurance Best Practices first-place award, recognizing our delivery of real time technology that increases agency efficiency. We are on track with plans to further deploy and improve our new policy administration systems. By continuing to strengthen service and respond fully to the needs of our agents and policyholders, we plan to create value over the long term for shareholders."
