Subsequent Events [Abstract]
Subsequent Events	NOTE 29 – Subsequent Events We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date. Based on the evaluation, we did not identify any recognized subsequent events that would have required adjustment to the consolidated financial statements; however, we identified the following non-recognized subsequent events: Redemption of 6.70% Senior Notes On January 15, 2015 (the “redemption date”), we redeemed 100% of our company’s outstanding 6.70% Senior Notes due 2022. The redemption price was equal to the sum of the principal amount of the Notes outstanding and accrued and unpaid interest on the Notes up to, but not including, the redemption date.
