Restructuring and Related Activities [Abstract]  
RESTRUCTURING
In prior years, we implemented significant restructuring plans that resulted in substantial charges for our real estate obligations. During the six months ended June 30, 2012, we recorded subsequent plan adjustments in sublease income assumptions for certain properties included in our previously-disclosed restructuring plans.
 
 The following table displays the restructuring activity and balances during the six months ended June 30, 2012 (in thousands):
