| Long-term debt description | Borrowings under the Senior Credit Agreement are secured by the trade receivables, inventory, personal property, equipment, and certain real property of the Company's significant domestic subsidiaries. The Senior Credit Agreement is also guaranteed by each of the Company's significant domestic subsidiaries. The Senior Credit Agreement provides for a revolving credit facility and letters of credit in an aggregate amount that does not exceed the lesser of (i) $200 million and (ii) a borrowing base determined by reference to the trade receivables, inventories, and property, plant, and equipment of the Company's significant domestic subsidiaries. The Company can request additional financing from the banks to increase the revolving credit facility to $250 million under the terms of the Senior Credit Agreement. The terms of the Senior Credit Agreement provide that the revolving credit facility will terminate on the earlier of October 10, 2016 or six months prior to the maturity date of the Company's 8% Notes, which are due December 1, 2015. All revolving credit borrowings must be repaid on or before the maturity date. Interest rates on the revolving credit facility continue to be based on the London Interbank Offering Rate (LIBOR) plus an additional margin of 2.0% to 2.5%. In addition, the revolving credit facility is subject to an annual commitment fee calculated as 0.375% of the daily average undrawn balance. Standby letters of credit of $13,995,000 have been issued under the Senior Credit Agreement to third parties on behalf of the Company as of March 31, 2012. These letters of credit reduce the amount otherwise available under the revolving credit facility. As of March 31, 2012, the Company had $140,337,000 of availability under the revolving credit facility. On a trailing four-quarter basis, the Senior Credit Agreement includes a single financial covenant that requires the Company to maintain a minimum fixed charge coverage ratio of 1.25 to 1.00 at the end of each quarter. As of March 31, 2012, the Company was in compliance with this financial covenant. The Senior Credit Agreement contains other provisions and events of default that are customary for similar agreements and may limit the Company's ability to take various actions. On December 8, 2005, the Company issued $204,000,000 of Senior Subordinated 8% Notes (8% Notes), due December 1, 2015, at a discount to yield 8.25%. The 8% Notes are guaranteed by certain existing and future domestic subsidiaries and are not subject to any sinking fund requirements. |
