During both the third quarter and first nine months of 2013, we repurchased, in the open market, $54.1 million in aggregate principal amount of our 6.70% Fixed-to-Floating Rate Junior Subordinated Debentures due 2067 (the “6.70% Debentures”), compared to repurchases of $0.5 million, $30.9 million, and $30.9 million during the third quarter, first nine months, and full year of 2012, respectively. Since the amount paid exceeded the carrying value of the debt we repurchased, we recognized losses on these extinguishments of $4.3 million during both the third quarter and first nine months of 2013, compared to $0.1 million, $1.8 million, and $1.8 million during the third quarter, first nine months, and full year of 2012, respectively. In addition, for the portion of the 6.70% Debentures we repurchased, we reclassified $0.8 million on a pretax basis, of the unrealized gain on forecasted transactions from accumulated other comprehensive income on the balance sheet to net realized gains on securities on the comprehensive income statement during both the third quarter and first nine months of 2013, compared to $0, $0.6 million, and $0.6 million during the third quarter, first nine months, and full year of 2012, respectively.

As of September 30, 2013, our next scheduled debt maturity was $150 million of our 7% Notes due 2013; these Notes were paid at maturity on October 1, 2013.
