| | (2) | Estimated fair value for the facility exit reserve is determined using the Company’s incremental borrowing rate at December 31, 2014 and March 31, 2014. At December 31, 2014 and March 31, 2014, the facility exit reserve included approximately $8 million and $11 million, respectively, in “Accrued expenses and other current liabilities” and approximately $13 million and $18 million, respectively, in “Other noncurrent liabilities” in the Company’s Condensed Consolidated Balance Sheets (Level 3). |
