A.M. Best Co. has assigned a debt rating of “bbb” to the $275 million 5.0% 10-year senior unsecured notes of Infinity Property & Casualty Corporation (Infinity) (headquartered in Birmingham, AL) (NASDAQ: IPCC) that were issued on September 19, 2012. The assigned outlook is stable. Infinity’s existing financial strength, issuer credit and debt ratings are unchanged. A.M. Best anticipates the proceeds from this issuance will be used to redeem the $195 million 5.5% 10-year senior unsecured notes due February 18, 2014. Any remaining proceeds will be used for general corporate purposes. While Infinity maintains financial leverage and interest coverage that are in line with its current ratings, its debt-to-total capital ratio has increased in the short term due to this additional debt issuance. However, it is projected to decrease to approximately 30.0% at year-end 2012. This is due to the planned redemption of the $195 million 5.5% 10-year senior unsecured notes, which is scheduled to take place on October 17, 2012. On March 21, 2012, A.M. Best affirmed Infinity’s ICR of “bbb” with a stable outlook. The methodology used in determining these ratings is Best’s Credit Rating Methodology , which provides a comprehensive explanation of A.M.
