Restructuring [Abstract]
Restructuring	10. Restructuring Beginning in July 2011, we took steps to streamline our organization as part of our cost savings programs. This reorganization eliminated over 700 employee positions throughout the Company, including approximately 300 open positions. Additionally, subsequent to our acquisition of Oakleaf, we incurred charges in connection with restructuring that organization. During the year ended December 31, 2011, we recognized a total of $19 million of pre-tax restructuring charges, of which $18 million were related to employee severance and benefit costs associated with these restructuring efforts. The remaining charges were primarily related to operating lease obligations for property that will no longer be utilized. During the three months ended March 31, 2012, we recognized additional employee severance and benefit restructuring charges, including $2 million associated with the reorganization of Oakleaf and $2 million associated with certain other actions taken by the Company in our Southern Group. Through March 31, 2012, we have paid approximately $13 million of the employee severance and benefit costs incurred as a result of these restructuring efforts.
