In July and August 2011, we repurchased, in privately negotiated transactions, approximately $84.9 million of certain of our 3.70% Unsecured Convertible Notes for an aggregate cash price of approximately $86.2 million.  As a result of these repurchases, we recognized a loss on early extinguishment of debt of approximately $2.0 million, including approximately $0.2 in unamortized issuance costs.
