Non - GAAP Reconciliations 7 Q&A

Non - GAAP Reconciliations Non - GAAP Financial Measures The following tables show reconciliations of non - GAAP financial measures. The reasons Delta uses these measures are described be low. Reconciliations may not calculate due to rounding. Delta sometimes uses information ("non - GAAP financial measures") that is derived from the Consolidated Financial Statements, but that is not presented in accordance with accounting principles generally accepted in the U.S. (“GAAP”). Under the U.S. Securities and Exchange Commission rules, non - GAAP financial measures ma y be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for or superior to GAAP results. The tables below show reconc ili ations of non - GAAP financial measures used in this presentation to the most directly comparable GAAP financial measures. Forward Looking Projections. The company is not able to reconcile certain forward looking non - GAAP financial measures because the adjusting items such as th ose used in the reconciliations below will not be known until the end of the period and could be significant. 8 Pre - Tax Income, Adjusted We adjust pre - tax income for mark - to - market ("MTM") adjustments and settlements on fuel hedge contracts, equity investment MTM a djustments, restructuring and other and loss on extinguishment of debt to determine pre - tax income, adjusted for the reasons described below. MTM adjustments and settlements. MTM adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value chang es are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period. Settlements represent ca sh received or paid on hedge contracts settled during the period. Equity investment MTM adjustments. We record our proportionate share of earnings/loss from our equity investments in Virgin Atlantic in non - operating expense. We adjust for our equity method investee's MTM adjustments to allow investors to better understand and analyze our core financial performance in the p eri ods shown. Restructuring and other and Loss on extinguishment of debt. Because of the variability from period to period, the adjustments for these items are helpful to investors to analyze the company’s recurring core performance in the periods shown.
