| Restructuring and Related Charges     | Restructuring ChargesWe recognize restructuring charges when a plan that materially changes the scope of our business or the manner in which that business is conducted is adopted and communicated to the impacted parties, and the expenses have been incurred or are reasonably estimable. In addition, we assess the property and equipment associated with the related facilities for impairment. The remaining useful lives of property and equipment associated with the related operations are re-evaluated based on the respective restructuring plan, resulting in the acceleration of depreciation and amortization of certain assets.Fiscal 2012 Restructuring ActivityIn the first quarter of fiscal 2012, we announced restructuring actions, including the relocation of our corporate services from Solon, Ohio to Alpharetta, Georgia, designed to better align those services with our operating units and reduce costs following the sale of TSG. These restructuring actions were mostly completed by March 31, 2012 and impacted approximately 130 employees. To date, we have recorded $12.1 million in restructuring charges, of which $1.2 million was recorded in the first nine months of fiscal 2013, related to the fiscal 2012 restructuring activity.  These charges were primarily comprised of severance and related benefits. On a segment basis, these restructuring costs totaled $2.6 million, $0.6 million, and $8.9 million for HSG, RSG and Corporate/Other, respectively. As of December 31, 2012, we had a remaining liability of approximately $0.6 million recorded for fiscal 2012 restructuring activity.  As a result of taking these restructuring actions, we expect to realize between $14.0 million and $16.0 million in cost savings, of which approximately half has been recognized in the fiscal 2012 run rate.  The remaining savings have been realized during fiscal 2013. Fiscal 2009 Restructuring ActivityDuring fiscal 2009, we took steps to realign our cost and management structure. Since 2009, as previously disclosed, we have incurred charges totaling approximately $19.0 million related to the fiscal 2009 restructuring activity. As of December 31, 2012, we had a remaining liability of approximately $0.3 million recorded for fiscal 2009 restructuring activity. We expect to incur minimal additional restructuring charges between fiscal 2013 and fiscal 2014 for ongoing facility obligations.Following is a reconciliation of the beginning and ending balances of the restructuring liability: Balance at     Balance at  March 31,     December 31,(In thousands)2012 Provision Payments 2012Fiscal 2012 Restructuring Plan:       Severance and employment costs$5,507 $1,236 $(6,118) $625Facilities costs297 (57) (240) —Fiscal 2009 Restructuring Plan:       Facilities costs495 3 (192) 306Total restructuring costs$6,299 $1,182 $(6,550) $931Approximately $0.1 million of the remaining severance and other employment costs will be paid in fiscal 2013 and $0.5 million will be paid in fiscal 2014.
