Consolidating Financials [Abstract] |
Supplemental Guarantor Information | Guarantor Information On November 20, 2012, GrafTech International Ltd. (the “Parent”) issued $300 million aggregate principal amount of Senior Notes. The Senior Notes mature on November 15, 2020 and bear interest at a rate of 6.375% per year, payable semi-annually in arrears on May 15 and November 15 of each year. The Senior Notes have been guaranteed on a senior basis by the following wholly-owned direct and indirect subsidiaries of the Parent: GrafTech Finance Inc., GrafTech Holdings Inc., GrafTech USA LLC, Seadrift Coke LLP, Fiber Materials, Inc., Intermat, GrafTech Global Enterprises Inc., GrafTech International Holdings Inc., GrafTech DE LLC, GrafTech Seadrift Holding Corp, GrafTech International Trading Inc., GrafTech Technology LLC, GrafTech NY Inc., and Graphite Electrode Network LLC. The guarantors of the Senior Notes, solely in their respective capacities as such, are collectively called the “Guarantors.” Our other subsidiaries, which are not guarantors of the Senior Notes, are called the “Non-Guarantors.” All of the guarantees are unsecured. All of the guarantees are full, unconditional (subject to limited exceptions described below) and joint and several. Each of the Guarantors are 100% owned, directly or indirectly, by the Parent. All of the guarantees of the Senior Notes continue until the Senior Notes have been paid in full, and payment under such guarantees could be required immediately upon the occurrence of an event of default under the Senior Notes. If a Guarantor makes a payment under its guarantee of the Senior Notes, it would have the right under certain circumstances to seek contribution from the other Guarantors. The Guarantors will be released from the guarantees upon the occurrence of certain events, including the following: the unconditional release or discharge of any guarantee or indebtedness that resulted in the creation of the guarantee of the Senior Notes by such Guarantor; the sale or other disposition, including by way of merger or consolidation or the sale of its capital stock, following which such Guarantor is no longer a subsidiary of the Parent; or the Parent's exercise of its legal defeasance option or its covenant defeasance option as described in the indenture applicable to the Senior Notes. If any Guarantor is released, no holder of the Senior Notes will have a claim as a creditor against such Guarantor. The indebtedness and other liabilities, including trade payables and preferred stock, if any, of each Guarantor are effectively senior to the claim of any holders of the Senior Notes. Investments in subsidiaries are recorded on the equity basis. The following tables set forth condensed consolidating balance sheets as of December 31, 2014 and September 30, 2015 and condensed consolidating statements of operations and comprehensive income for the three and nine months ended September 30, 2014 and the periods July 1 and January 1 through August 14, 2015 (Predecessor) and the period August 15 through September 30, 2015 (Successor) and condensed consolidating statements of cash flows for the nine months ended September 30, 2014 and and the period January 1 through August 14, 2015 (Predecessor) and the period August 15 through September 30, 2015 (Successor) of the Parent Guarantors and the Non-Guarantors.
