Segment Reporting [Abstract]  
Segment and Related Information​ Segment and Related Information​
Effective in the second quarter of 2020, management elected to change the profit or loss measure of the Company’s reportable segments from Segment operating profit to Segment Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) for internal reporting and performance measurement purposes. This change was made to enhance the transparency and visibility of the underlying operating performance of each segment. Arconic Corporation calculates Segment Adjusted EBITDA as Total sales (third-party and intersegment) minus each of (i) Cost of goods sold, (ii) Selling, general administrative, and other expenses, and (iii) and Research and development expenses, plus Stock-based compensation expense. Previously, the Company calculated Segment operating profit as Segment Adjusted EBITDA minus both Stock-based compensation expense and the Provision for depreciation and amortization. Arconic Corporation’s Segment Adjusted EBITDA may not be comparable to similarly titled measures of other companies’ reportable segments. Segment information for all prior periods presented was recast to reflect the new measure of segment profit or loss.
The operating results of the Company’s reportable segments were as follows (differences between segment totals and consolidated amounts are in Corporate):

(1)In preparation for the Separation, effective January 1, 2020, certain U.S. defined benefit pension and other postretirement plans previously sponsored by ParentCo were separated into standalone plans for both Arconic Corporation and Howmet Aerospace. Additionally, effective April 1, 2020, Arconic Corporation assumed a portion of the obligations associated with certain non-U.S. defined benefit pension plans that included participants related to both the Arconic Corporation Businesses and the Howmet Aerospace Businesses, as well as legacy defined benefit pension plans assigned to the Company as a result of the Separation. As a result, beginning in the first quarter of 2020 for these U.S. plans and in the second quarter of 2020 for these non-U.S. plans, Arconic Corporation applied defined benefit plan accounting resulting in
benefit plan expense being recorded in operating income (service cost) and nonoperating income (nonservice cost). In all historical periods prior to these respective timeframes, Arconic Corporation was considered a participating employer in ParentCo’s defined benefit plans and, therefore, applied multiemployer plan accounting resulting in the Company’s share of benefit plan expense being recorded entirely in operating income. Also, Arconic Corporation is the plan sponsor of certain other non-U.S. defined benefit plans that contain participants related only to the Arconic Corporation Businesses and, therefore, the related benefit plan expense was recorded in accordance with defined benefit plan accounting in all periods presented. The following table presents the total benefit plan expense (excluding settlements and curtailments) recorded by Arconic Corporation based on the foregoing in each period presented:
