Table of Contents The following table presents the components of our total net special items and the reconciliation of pre-tax income (loss) and net income (loss) (GAAP measures) to pre-tax income (loss) excluding net special items and net income (loss) excluding net special items (non-GAAP measures). Management uses pre-tax income (loss) excluding net special items and net income (loss) excluding net special items to evaluate our current operating performance and to allow for period-to-period comparisons. As net special items may vary from period-to-period in nature and amount, the adjustment to exclude net special items allows management an additional tool to understand our core operating performance. 61 Year Ended December 31, 2020 2019 (In millions) Components of Total Special Items, Net:  PSP1 Financial Assistance  $ (3,710) $ —  Fleet impairment  1,484  213  Severance expenses  1,408  11  Labor contract expenses  228  —  Mark-to-market adjustments on bankruptcy obligations, net  (49) (11) Fleet restructuring expenses  —  271  Merger integration expenses  —  191  Litigation reserve adjustments —  (53) Other operating special items, net (18) 13  Mainline operating special items, net (657) 635  PSP1 Financial Assistance  (444) —  Fleet impairment  117  —  Severance expenses  18  —  Other operating special items, net —  6  Regional operating special items, net (309) 6  Operating special items, net (966) 641  Mark-to-market adjustments on equity and other investments, net  135  (5) Debt refinancing, extinguishment and other, net 35  8  Nonoperating special items, net 170  3  Pre-tax special items, net (796) 644  Total special items, net $ (796) $ 644  Reconciliation of Pre-Tax Income (Loss) Excluding Net Special Items: Pre-tax income (loss) – GAAP $ (11,453) $ 2,256  Adjusted for: Pre-tax special items, net (796) 644  Pre-tax income (loss) excluding net special items $ (12,249) $ 2,900  Reconciliation of Net Income (Loss) Excluding Net Special Items: Net income (loss) – GAAP $ (8,885) $ 1,686  Adjusted for: Total special items, net (796) 644  Adjusted for: Net tax effect of net special items 170  (151) Net income (loss) excluding net special items $ (9,511) $ 2,179  (1) (2) (3) (4) (5) (6) (7) (8) (2) (3) (4) (9) See Note 2 to AAG’s Consolidated Financial Statements in Part II, Item 8A for further information on net special items.
