Non-GAAP Financial Measures In addition to financial information prepared in accordance with generally accepted accounting principles in the United States ("GAAP"), this presentation includes certain non-GAAP financial measures. We believe these non-GAAP financial measures are useful indicators of our operating performance. Derivations of net income and EBITDA are well recognized performance measurements in the airline industry that are frequently used by our management, as well as by investors, securities analysts and other interested parties in comparing the operating performance of companies in our industry. Reconciliations of such information to the most directly comparable GAAP financial measures are included in the Appendix to these slides. The non-GAAP measures have limitations, and you should not consider them in isolation or as a substitute for our GAAP financial information. Special Note Regarding Forward-Looking Statements This presentation contains forward-looking statements. All statements other than statements of historical facts contained in this presentation, including statements regarding our future results of operations and financial position, business strategy, order book, aircraft and engine performance, competitive positioning, potential market size and growth, availability of financing, continued impact of the COVID-19 pandemic, expected recovery of the airline industry after the COVID-19 pandemic, and plans and objectives of management for future operations are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur and actual results could differ materially from those projected in the forward-looking statements. Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained herein, whether as a result of any new information, future events, changed circumstances or otherwise. Statistical Data, Estimates and Forecasts This presentation contains statistical data, estimates and forecasts that are based on independent industry publications or other publicly available information, as well as other information based on our internal sources. This information involves many assumptions and limitations, and you are cautioned not to give undue weight to these estimates. We have not independently verified the accuracy or completeness of the data contained in these industry publications and other publicly available information. Accordingly, we make no representations as to the accuracy or completeness of that data nor do we undertake to update such data after the date of this presentation.
