At December 31, 2011, our net investment in discontinued operations primarily consisted of a $225 performance-based instrument relating to the 1997 sale of The Resolution Group (“TRG”) net of remaining net liabilities associated with our discontinued operations of $21. The recovery of the performance-based instrument is dependent on the sufficiency of TRG's available cash flows, as guaranteed by TRG's ultimate parent, which are expected to be recovered in annual cash distributions through 2017. In 2011, the performance-based instrument was pledged as security for our future funding obligations to our U.K. Pension Plan for salaried employees.
