Subsequent Events [Abstract]
Subsequent Events	(18)Subsequent Events: We repurchased $208.8 million of the 2017 Notes in a privately negotiated transaction for $250.6 million that was settled with cash on hand on April 2, 2013. This repurchase resulted in a loss on the early extinguishment of debt of approximately $41.1 million ($25.4 million or $0.03 per share after tax), which will be recognized in the second quarter of 2013. On April 10, 2013, the Company completed a registered debt offering of $750.0 million aggregate principal amount of 7.625% senior unsecured notes due 2024, issued at a price of 100% of their principal amount. We received net proceeds of $736.9 million from the offering after deducting underwriting fees. The Company used the net proceeds from the sale of the notes, together with cash on hand, to finance the cash tender offers discussed below. On April 10, 2013, the Company accepted for purchase $471.3 million aggregate principal amount of its senior notes tendered for total consideration of $532.4 million, consisting of $194.2 million aggregate principal amount of the 6.625% senior notes due 2015 (the March 2015 Notes), tendered for total consideration of $216.0 million, and $277.1 million aggregate principal amount of the 7.875% senior notes due 2015 (the April 2015 Notes), tendered for total consideration of $316.4 million, respectively. On April 24, 2013, the Company accepted for purchase $0.7 million aggregate principal amount of the March 2015 Notes, tendered for total consideration of $0.8 million, $0.8 million of the April 2015 Notes, tendered for total consideration of $0.9 million, and $225.0 million aggregate principal amount of the 8.250% senior notes due 2017 (the 2017 Notes), tendered for total consideration of $267.7 million, respectively. The repurchases in the debt tender offers for the senior notes resulted in a loss on the early extinguishment of debt of approximately $102.7 million, ($63.6 million or $0.06 per share after tax), which will be recognized in the second quarter of 2013. As of April 30, 2013, approximately $105.0 million aggregate principal amount of the March 2015 Notes, $96.9 million aggregate principal amount of the April 2015 Notes and $606.9 million aggregate principal amount of the 2017 Notes remained outstanding. The Company has entered into a new $750.0 million revolving credit facility (the New Credit Facility). The terms of the New Credit Facility are set forth in the credit agreement, dated as of May 3, 2013, among the Company, the Lenders party thereto, JPMorgan Chase Bank, N.A., as Administrative Agent and the joint lead arrangers, joint bookrunners, syndication agent and joint documentation agents named therein (the New Revolving Credit Agreement). Associated facility fees under the New Credit Facility will vary from time to time depending on the Company's debt rating (as defined in the New Revolving Credit Agreement). The New Credit Facility is scheduled to terminate on November 3, 2016. During the term of the New Credit Facility, the Company may borrow, repay and reborrow funds, and may obtain letters of credit, subject to customary borrowing conditions. Loans under the New Credit Facility will bear interest based on the alternate base rate or the adjusted LIBO rate (each as determined in the New Revolving Credit Agreement), at the Company's election, plus a margin specified in the New Revolving Credit Agreement based on the Company's debt rating. Letters of credit issued under the New Credit Facility will also be subject to fees that vary depending on the Company's debt rating. The New Credit Facility is available for general corporate purposes but may not be used to fund dividend payments. During 2012, the Company entered into an agreement with Verizon Wireless to sell its 33⅓% partnership interest in the Mohave Cellular Limited Partnership, in which Frontier was the General Partner. We closed on the sale on April 1, 2013, and we will recognize a gain on sale of approximately $15.3 million before taxes in the second quarter of 2013. As of March 31, 2013, Mohave is consolidated within Frontier's financial statements, with the non-controlling interest portion separately identified and disclosed, and net assets of approximately $12.1 million classified as held-for-sale, consisting of $14.3 million included within "Income taxes and other assets" and $2.2 million included within "Other current liabilities" as of March 31, 2013.
