Non-GAAP Reconciliation

(a) One-time adjustment related to the amendment of the Company's co-branded credit card agreement with Chase Bank USA, N.A. and a resulting change in accounting methodology. (b) Expenses associated with the Company’s acquisition and integration of AirTran Holdings, LLC, the parent company of AirTran Airways, Inc. ("AirTran"). Such expenses were primarily incurred during the acquisition and integration period of the two companies from 2011 through 2015 as a result of the Company’s acquisition of AirTran, which closed on May 2, 2011. The exclusion of these expenses provides investors with a more applicable basis with which to compare results in future periods now that the integration process has been completed. Further, pursuant to the terms of the Company’s ProfitSharing Plan, acquisition and integration costs were excluded from the calculation of profitsharing expense from April 1, 2011, through Dec. 31, 2013. These costs, totaling $385 million, are being amortized on a pro rata basis as a reduction of operating profits, as defined by the ProfitSharing Plan, from 2014 through 2018, in the calculation of profitsharing. In addition, acquisition and integration costs incurred during 2014 and 2015 will reduce operating profits, as defined, in the calculation of profitsharing. (c) Tax amounts for each individual special item are calculated at the Company's effective rate for the applicable period and totaled in this line item. (d) Adjustment related to the Tax Cuts and Jobs Act legislation passed in December 2017, which resulted in a re-measurement of the Company's deferred tax assets and liabilities at the new corporate tax rate. (e) Includes the impact of the AirTran acquisition as of May 2, 2011. (f) These results will be recast primarily due to the retrospective application transition option selected as part of the Company’s adoption of Accounting Standards Update 2014-09, Revenue from Contracts with Customers. See the Company’s Current Report on Form 8-K furnished to the Securities and Exchange Commission on March 20, 2018 for further information.

Such expenses were primarily incurred during the acquisition and integration period of the two companies from 2011 through 2015 as a result of the Company’s acquisition of AirTran, which closed on May 2, 2011. The exclusion of these expenses provides investors with a more applicable basis with which to compare results in future periods now that the integration process has been completed. Further, pursuant to the terms of the Company’s ProfitSharing Plan, acquisition and integration costs were excluded from the calculation of profitsharing expense from April 1, 2011, through Dec. 31, 2013. These costs, totaling $385 million, are being amortized on a pro rata basis as a reduction of operating profits, as defined by the ProfitSharing Plan, from 2014 through 2018, in the calculation of profitsharing. In addition, acquisition and integration costs incurred during 2014 and 2015 will reduce operating profits, as defined, in the calculation of profitsharing. (c) Net adjustment related to presumption that all aircraft in fleet are owned (i.e., the impact of eliminating aircraft rent expense and replacing with estimated depreciation expense for those same aircraft). The Company makes this adjustment to enhance comparability to other entities that have different capital structures by utilizing alternative financing decisions. (d) The Adjustment for fuel hedge accounting in the numerator is due to the Company's accounting policy decision to classify fuel hedge accounting premiums below the Operating income line, and thus is adjusting Operating income to reflect such policy decision. The Equity adjustment for hedge accounting in the denominator adjusts for the cumulative impacts, in Accumulated other comprehensive income and Retained earnings, of gains and/or losses associated with hedge accounting related to fuel hedge derivatives that will settle in future periods. The current period impact of these gains and/or losses are reflected in the Net impact from fuel contracts in the numerator. (e) Calculated as an average of the five most recent quarter end balances or remaining obligations. The Net present value of aircraft operating leases represents the assumption that all aircraft in the Company's fleet are owned, as it reflects the remaining contractual commitments discounted at its estimated incremental borrowing rate as of the time each individual lease was signed. (f) Includes the impact of the AirTran acquisition as of May 2, 2011. (g) These results will be recast primarily due to the retrospective application transition option selected as part of the Company’s adoption of Accounting Standards Update 2014-09, Revenue from Contracts with Customers. See the Company’s Current Report on Form 8-K furnished to the Securities and Exchange Commission on March 20, 2018 for further information. (h) As the twelve month rolling tax rate no longer approximates an annual tax rate due to the significant impact the Tax Cuts and Jobs Act legislation enacted in December 2017 had on corporate tax rates, the Company is utilizing the 2018 year-to-date tax rate for 2018 ROIC, after-tax. The 2018 year-to-date GAAP tax rate was 22.8 percent, and the Non-GAAP tax rate for the period was also 22.8 percent. Utilizing the Company’s tax rate based on Operating income, non-GAAP for the twelve months ended September 30, 2018, of 25.7 percent, Non-GAAP ROIC, after tax, would have been 17.4 percent..
