In 2020, the majority of our customer contractual terms were amended in a manner that resulted in moving from recognizing wafer revenue on a Percentage-of-Completion basis to recognizing revenue on a Wafer Shipment basis. This resulted in a one-time, non-recurring reduction in net revenues recognized in 2020. Had the change in terms not occurred, net revenues for the quarter ended December 31, 2020 would have been an estimated $501 million higher than reported results. 2. We define adjusted EBITDA as net income (loss), excluding the impact of interest expense, tax expense, depreciation, amortization adjusted for share-based compensation expense, transaction gains and associated expenses, restructuring charges and litigation settlements; a reconciliation of adjusted non-IFRS to IFRS metrics can be found in the appendix.
