Item 3. Quantitative and Qualitative Disclosures About Market Risk

As of August 31, 2023, there were no material changes in our market risk sensitive instruments and positions since our disclosures in our Annual Report.

The principal foreign currency exchange rate risks to which we are exposed relate to the euro, Chinese yuan, British pound, Canadian dollar, Hong Kong dollar, Australian dollar, Japanese yen, and Mexican peso. Historically, our exposure to foreign currency fluctuations is more significant with respect to our revenue than our expenses, as a significant portion of our expenses are denominated in U.S. dollars, such as aircraft and fuel expenses. During the first quarter of 2024, the U.S. dollar strengthened relative to the currencies of the foreign countries in which we operate, as compared to the first quarter of 2023, and this strengthening had a slightly negative effect on our results.

While we have market risk for changes in the price of vehicle and jet fuel, this risk is largely mitigated by our indexed fuel surcharges. For additional discussion of our indexed fuel surcharges, see the “Results of Operations and Outlook — Consolidated Results —Fuel” section of “Item 7. Management’s Discussion and Analysis of Results of Operations and Financial Condition” included in our Annual Report.
