Restructuring Charges [Abstract]
Restructuring Charges	Note N -- Restructuring Charges In the third quarter of fiscal 2012, the Company announced a restructuring initiative (“2012 Restructuring Plan”) that committed to the closing of two of the Company’s manufacturing plants located in Hardy County, West Virginia and Hazard, Kentucky, offering its previously idled plant in Tahlequah, Oklahoma for sale, and realigning its retirement program, including freezing the Company’s defined benefit pension plans. Operations ceased at the Hazard plant in April 2012 and at the Hardy County plant in May 2012. The 2012 Restructuring Plan was adopted to reduce costs and increase the Company’s capacity utilization rates. In the fourth quarter of fiscal 2009, the Company announced a restructuring plan (“2009 Restructuring Plan”) to close two of its manufacturing plants, located in Berryville, Virginia and Moorefield, West Virginia and suspend operations in a third manufacturing plant located in Tahlequah, Oklahoma. These actions were completed during the first quarter of fiscal 2010. These initiatives were intended to increase the Company’s capacity utilization rates and decrease overhead costs. In addition to these initiatives, the Company made other staffing reductions during the fourth quarter of fiscal 2009. During fiscal years 2014, 2013 and 2012, the Company recognized total pre-tax restructuring charges for both the 2012 Restructuring Plan and the 2009 Restructuring Plan of $(234,000), $1.4 million and $16.3 million, respectively. The Company recognized recurring operating costs for the facilities closed as part of the 2012 Restructuring Plan of $0.3 million in fiscal 2014. These costs will continue until the remaining closed plant is sold. The Company has one manufacturing plant classified as held for sale, which was closed in the 2012 Restructuring Plan. During the fourth quarter of fiscal 2014, the Company sold its closed plant located in Hazard, Kentucky and recognized a gain of $0.3 million on the sale. The gain was included in restructuring charges on the Company’s statements of operations. The Company believes that the remaining $1.0 million net book value of the property classified as held for sale is fully recoverable. This asset is included in Other Assets on the Company’s balance sheet at April 30, 2014.
