(A)Metal price lag represents the financial impact of the timing difference between when aluminium prices included within Constellium's Revenue are established and when aluminium purchase prices included in Cost of sales are established. The Group accounts for inventory using a weighted average price basis and this adjustment aims to remove the effect of volatility in LME prices. The calculation of the Group metal price lag adjustment is based on an internal standardized methodology calculated at each of Constellium’s manufacturing sites and is primarily calculated as the average value of product recorded in inventory, which approximates the spot price in the market, less the average value transferred out of inventory, which is the weighted average of the metal element of cost of sales, based on the quantity sold in the year. (B)Start-up and development costs, for the years ended December 31, 2020, 2019 and 2018, were related to new projects in our AS&I operating segment. (C)Bowling Green one-time costs related to the acquisition, for the year ended December 31, 2019, was the non-cash reversal of the inventory step-up. (D)The Group amended one of its OPEB plans in the U.S. in 2018, which resulted in a €36 million gain for the year ended December 31, 2018. (E)In July 2018, Constellium completed the sale of the North Building assets of its Sierre plant in Switzerland to Novelis and contributed the Sierre site shared infrastructure to a joint-venture with Novelis, in exchange for cash consideration of €200 million. This transaction also resulted in the termination of the existing lease agreement for the North Building assets which had been leased and operated by Novelis since 2005. For the year ended December 31, 2018, the transaction generated a €190 million net gain. (See NOTE 31 - Subsidiaries and Operating Segments). (F)Other, in the year ended December 31, 2020, includes €2 million of procurement penalties and termination fees incurred because of the Group's inability to fulfill certain commitments due to the COVID-19 pandemic and a €6 million loss resulting from the discontinuation of hedge accounting for certain forecasted sales that were determined to be no longer expected to occur in light of the COVID-19 pandemic effects.
