Restructuring and Related Activities [Abstract]
Restructuring Charges	Restructuring Charges Employee Separations Changing economic and business conditions as well as organizational structure optimization efforts have caused the Company to initiate from time to time various workforce reductions resulting in involuntary employee terminations. The Company also has initiated multiple workforce reductions resulting from the integration of previously acquired companies. During 2012 and 2011, the Company initiated workforce reductions primarily as a result of the Amalgamation. During 2010, the Company did not initiate any significant workforce reductions. Restructuring charges totaled $34 million, $11 million and $2 million in 2012, 2011 and 2010, respectively. As of December 31, 2012 and 2011, the Company had $16 million and $5 million, respectively, of employee termination liabilities. Facility Closings The Company also has accrued contract termination costs of $35 million and $43 million as of December 31, 2012 and December 31, 2011, respectively, for facility lease costs that the Company continues to incur without economic benefit. Accrued contract termination costs are recorded in other liabilities (current and non-current) in the consolidated balance sheets. The Company expects to pay the majority of these costs through 2025. The Company recognized a charge of approximately $2 million, and a benefit of $3 million and $5 million in 2012, 2011 and 2010, respectively, as a result of lease modifications.
