Given the risks and uncertainties surrounding forward-looking statements, you should not place undue reliance on these statements. You should understand that many important factors, in addition to those discussed or incorporated by reference in this Investor Update, could cause our results to differ materially from those expressed in the forward-looking statements. Further information concerning these and other factors is contained in JetBlue's filings with the U.S. Securities and Exchange Commission (the "SEC"), including but not limited to in our Annual Report on Form 10-K for the year ended December 31, 2023, as may be updated by our other SEC filings. In light of these risks and uncertainties, the forward-looking events discussed in this Investor Update might not occur. Our forward-looking statements speak only as of the date of this Investor Update. Other than as required by law, we undertake no obligation to update or revise forward-looking statements, whether as a result of new information, future events, or otherwise.
We report our financial results in accordance with GAAP; however, we present certain non-GAAP financial measures in this Investor Update. Non-GAAP financial measures are financial measures that are derived from the condensed consolidated financial statements, but that are not presented in accordance with GAAP. We present these non-GAAP financial measures because we believe they provide useful supplemental information that enables a meaningful comparison of our results to others in the airline industry and our prior year results. Investors should consider these non-GAAP financial measures in addition to, and not as a substitute for, our financial measures prepared in accordance with GAAP. Further, our non-GAAP information may be different from the non-GAAP information provided by other companies.
With respect to JetBlue’s CASM Ex-Fuel (1) guidance , we are not able to provide a reconciliation of forward-looking measures where the quantification of certain excluded items reflected in the measures cannot be calculated or predicted at this time without unreasonable efforts. In these cases, the reconciling information that is unavailable includes a forward-looking range of financial measures beyond our control, such as fuel costs, which are subject to many economic and political factors beyond our control. For the same reasons, we are unable to address the probable significance of the unavailable information, which could have a potentially unpredictable and potentially significant impact on our future GAAP financial results.
(1) CASM Ex-Fuel is a non-GAAP measure that excludes fuel, other non-airline operating expenses, and special items.
