[1] | We included our 6.25% Senior Unsecured Notes due 2014 (the "6.25% Notes") in the current portion of long-term debt on our December 31, 2013 Consolidated Balance Sheet because the 6.25% Notes were scheduled to mature on November 15, 2014. We redeemed the 6.25% Notes prior to their scheduled maturity during the second quarter of 2014.
