7 Q&A

Non-GAAP Financial Measures

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 may 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 table below shows a reconciliation of the non-GAAP financial measure used in this presentation to the most directly comparable GAAP financial measure. The reconciliation may not calculate due to rounding.

Delta is not able to reconcile certain forward looking non-GAAP financial measures used in this presentation without unreasonable effort because the adjusting items such as those used in the reconciliations below will not be known until the end of the indicated future periods and could be significant.

Non-GAAP Financial Measures

After-tax Return on Invested Capital ("ROIC"). We present after-tax return on invested capital as management believes this metric is helpful to investors in assessing the company's ability to generate returns using its invested capital. Return on invested capital is tax-effected adjusted operating income (using our effective tax rate for each respective period) divided by average adjusted invested capital. Average stockholders' equity and average adjusted gross debt are calculated using amounts as of the end of the current period and comparable period in the prior year. All adjustments to calculate ROIC are intended to provide a more meaningful comparison of our results to comparable companies.

MTM adjustments and settlements on hedges. Mark-to-market ("MTM") adjustments are defined as fair value changes recorded in periods other than the settlement period. MTM fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period. Settlements represent cash received or paid on hedge contracts settled during the applicable period.

Interest expense included in aircraft rent. This adjustment relates to interest expense related to operating lease financing transactions. Adjusting for these results allows investors to better understand our core operational performance in the periods shown as it neutralizes the effect of lease financing structure.
