LONG-LIVED ASSETS As disclosed in Note 3, in May 2020, the Company’s Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand and (ii) to transfer the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities (as disclosed in Note 3, this transaction closed in August 2020). These planned divestitures represent the divestiture of certain assets and liabilities of an operating business within the Aerospace Structures segment that the Company has identified as an asset group pursuant to the provisions of ASC 360, Property, Plant, and Equipment. As a result, as of May 31, 2020, the Company concluded that the planned divestitures represented a significant change in the manner in which the related asset group was expected to be used, and that the asset group therefore needed to be tested for recoverability. The asset group primarily consists of working capital, fixed assets and definite-lived intangible assets. The Company first determined that the relevant long-lived asset group was not recoverable by comparing the undiscounted cash flows expected to be generated by the long-lived asset group to the carrying value of the asset group. As a result, the Company estimated the fair value of the long-lived asset group and concluded that the asset group was impaired. The Company used a multi-period excess earnings approach to estimate the fair value of the long-lived asset group for purposes of testing the asset group for impairment. This method estimates fair value based on the expected future excess earnings stream attributable to the asset group. This method requires the use of several key assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. A discount rate of 15.0% was applied to the estimated future excess earnings and cash flows in order to estimate the fair value of the asset group as of the measurement date. The Company has determined that the lowest level of the inputs that are significant to the fair value measurement are unobservable inputs that fall within Level 3 of the fair value hierarchy. In accordance with ASC 360, the Company allocated the resulting impairment to the specific long-lived assets within the asset group on a pro rata basis, except that the loss allocated to an individual long-lived asset of the group did not reduce the carrying amount of that asset below its estimated fair value. As a result, the Company recognized a total noncash impairment charge of $252,382, primarily allocated to definite-lived intangible assets, which is presented as “Impairment of long-lived assets” on the condensed consolidated statements of operations.

As disclosed in Note 3, in May 2020, the Company’s Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand and (ii) to transfer the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities (as disclosed in Note 3, this transaction closed in August 2020).
