Disclosure of Impairment of Long-Lived Assets [Abstract] |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the asset’s carrying amount may not be recoverable. The Company conducts its long-lived asset impairment analyses in accordance with ASC 360-10-15, "Impairment or Disposal of Long-Lived Assets." ASC 360-10-15 requires the Company to group assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities and evaluate the asset group against the sum of the undiscounted future cash flows. If the undiscounted cash flows do not indicate the carrying amount of the asset group is recoverable, an impairment charge is measured as the amount by which the carrying amount of the asset group exceeds its fair value based on discounted cash flow analysis or appraisals. In the first, second and third quarters of fiscal 2017, the Company concluded it had triggering events requiring assessment of impairment for certain of its long-lived assets in conjunction with its restructuring actions announced in fiscal 2017. As a result, the Company reviewed the long-lived assets for impairment and recorded $69 million of asset impairment charges within restructuring and impairment costs on the consolidated statements of income, of which $15 million was recorded in the first quarter, $23 million was recorded in the second quarter and $31 million was recorded in the third quarter. Of the total impairment charges, $27 million related to the Tyco segment, $20 million related to the Building Efficiency Products North America segment, $17 million related to Corporate assets, $4 million related to the Power Solutions segment, and $1 million related to the Building Efficiency Systems and Services North America segment. Refer to Note 9, "Significant Restructuring and Impairment Costs," of the notes to consolidated financial statements for additional information. The impairments were measured, depending on the asset, under either an income approach utilizing forecasted discounted cash flows or a market approach utilizing an appraisal to determine fair values of the impaired assets. These methods are consistent with the methods the Company employed in prior periods to value other long-lived assets. The inputs utilized in the analyses are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, "Fair Value Measurement." In the second and third quarters of fiscal 2016, the Company concluded it had a triggering event requiring assessment of impairment for certain of its long-lived assets in conjunction with its restructuring actions announced in fiscal 2016. As a result, the Company reviewed the long-lived assets for impairment and recorded $65 million of asset impairment charges within restructuring and impairment costs on the consolidated statements of income, of which $15 million was recorded in the second quarter and $50 million was recorded in the third quarter. Of the total impairment charge, $50 million related to Corporate assets, $8 million related to the Building Efficiency Products North America segment, $4 million related to the Building Efficiency Asia segment and $3 million related to the Building Efficiency Rest of World segment. In addition, the Company recorded $15 million of asset impairments within discontinued operations related to Adient in fiscal 2016. Refer to Note 9, "Significant Restructuring and Impairment Costs," of the notes to consolidated financial statements for additional information. The impairments were measured, depending on the asset, under either an income approach utilizing forecasted discounted cash flows or a market approach utilizing an appraisal to determine fair values of the impaired assets. These methods are consistent with the methods the Company employed in prior periods to value other long-lived assets. The inputs utilized in the analyses are classified as Level 3 inputs within the fair value hierarchy as defined in ASC 820, "Fair Value Measurement." At June 30, 2017 and 2016, the Company concluded it did not have any other triggering events requiring assessment of impairment of its long-lived assets.
