Segment Information Arconic is a global leader in lightweight metals engineering and manufacturing. Arconics innovative, multi-material products, which include aluminum, titanium, and nickel, are used worldwide in aerospace, automotive, commercial transportation, building and construction, industrial applications, defense, and packaging. Arconic has two operating and reportable segments, which are organized by product on a worldwide basis: Engineered Products and Forgings (EP&amp;F) (formerly named the Engineered Products and Solutions segment) and Global Rolled Products (GRP) (see further details below). Segment performance under Arconics management reporting system is evaluated based on a number of factors; however, the primary measure of performance is Segment operating profit. Arconics definition of Segment operating profit is Operating income excluding Special items. Special items include Restructuring and other charges. Segment operating profit includes the impact of LIFO inventory accounting, metal price lag, intersegment profit eliminations, and derivative activities. Segment operating profit may not be comparable to similarly titled measures of other companies. Differences between segment totals and consolidated Arconic are in Corporate. In the third quarter of 2019, the Company realigned its operations by eliminating its Transportation and Construction Solutions (TCS) segment and transferring the Forged Wheels business to its EP&amp;F segment and the Building and Construction Systems (BCS) business to its GRP segment, consistent with how the Chief Executive Officer is assessing operating performance and allocating capital in conjunction with the planned separation of the Company (see Note S ). The Latin American extrusions business, which was formerly part of the Company's TCS segment until its sale in April of 2018 (see Note Q ), was moved to Corporate. In the first quarter of 2019, management transferred its aluminum extrusions operations (Aluminum Extrusions) from its Engineered Structures business unit within the EP&amp;F segment to the GRP segment, based on synergies with GRP including similar customer base, technologies, and manufacturing capabilities. Prior period financial information has been recast to conform to current year presentation. As a result of the elimination of the TCS segment in the third quarter of 2019 as noted above, the Company transferred its existing Forged Wheels goodwill of $7 and its existing BCS goodwill of $68 from the TCS segment to the EP&amp;F segment and GRP segment, respectively. Both Forged Wheels and BCS will continue to be reporting units for purposes of evaluating goodwill for impairment. In the second quarter of 2019, management transferred its castings operations from the Engineered Structures business unit to the Engine Products business unit within the EP&amp;F segment based on process expertise for investment castings that existed within Engine Products. As a result, goodwill of $105 was reallocated from the Engineered Structures reporting unit to the Engine Products reporting unit and these reporting units were evaluated for impairment during the second quarter of 2019. The estimated fair value of each of these reporting units substantially exceeded their carrying value; thus, there was no impairment. Also in the second quarter of 2019, as a result of the decline in the forecasted financial performance and related impairment of long-lived assets of the Disks asset group within the Engine Products business unit (see Note M ), an additional evaluation of the Engine Products reporting unit goodwill was performed. The estimated fair value of the reporting unit was substantially in excess of its carrying value; thus, there was no impairment of goodwill. As a result of the reorganization of Aluminum Extrusions in the first quarter of 2019 as noted above, management assessed and concluded that the remaining Engineered Structures business unit and the Aluminum Extrusions business unit represent reporting units for purposes of evaluating goodwill for impairment. Goodwill of $110 was reallocated from the Engineered Structures reporting unit to the Aluminum Extrusions reporting unit and these reporting units were evaluated for impairment during the first quarter of 2019. The estimated fair value of each of these reporting units substantially exceeded their carrying value; thus, there was no goodwill impairment.
