Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We have exposure to several types of market risk: changes in interest rates, foreign currency exchange rates, and equity prices.

We manage our exposure to interest rate risk and foreign currency risk through internally established policies and procedures and, when deemed appropriate, through the use of derivative financial instruments. We use foreign currency exchange derivative contracts to manage short-term foreign currency risk.

The objective of our policies is to mitigate potential income statement, cash flow, and fair value exposures resulting from possible future adverse fluctuations in rates. We evaluate our exposure to market risk by assessing the anticipated near-term and long-term fluctuations in interest rates and foreign currency exchange rates. This evaluation includes the review of leading market indicators, discussions with financial analysts and investment bankers regarding current and future economic conditions, and the review of market projections as to expected future rates. We utilize this information to determine our own investment strategies as well as to determine if the use of derivative financial instruments is appropriate to mitigate any potential future market exposure that we may face. Our policy does not allow speculation in derivative instruments for profit or, except in certain limited situations, execution of derivative instrument contracts for which there are no underlying exposures. We do not use financial instruments for trading purposes and are not a party to any leveraged derivatives. To the extent that changes in interest rates and foreign currency exchange rates affect general economic conditions, we would also be affected by such changes.

See Note 12 to our Consolidated Financial Statements for information about our convertible senior notes and other debt. Excluding the effect on the fair value of our convertible senior notes, a hypothetical 100 basis point (1.0%) decrease in interest rates would have resulted in an increase in the estimated fair value of our other debt of approximately $612 million and $522 million at December 31, 2023 and 2022, respectively. Our convertible senior notes are more sensitive to the equity market price volatility of our shares than changes in interest rates. The fair value of the convertible senior notes will likely increase as the market price of our shares increases and will likely decrease as the market price of our shares falls. Our convertible senior notes due in May 2025 are currently convertible at the option of the holder. If the note holders exercise their option to convert, we deliver cash to repay the principal amount of the notes and deliver shares of common stock or cash, at our option, to satisfy the conversion value in excess of the principal amount.

We face exposure to movements in foreign currency exchange rates as the financial results and the financial condition of our businesses outside of the U.S., which represent a substantial majority of our financial results, are translated from local currencies (principally Euros and British Pounds Sterling) into U.S. Dollars. For example, our total gross bookings increased by 24% in 2023 as compared to 2022, but without the impact of changes in foreign currency exchange rates our total gross bookings increased year-over-year on a constant-currency basis by approximately 25%. Our total revenues increased by 56% for the year ended December 31, 2022 as compared to the year ended December 31, 2021, but without the impact of changes in foreign currency exchange rates, our total revenues increased year-over-year on a constant-currency basis by approximately 71%. See Notes 6, 12, and 19 to our Consolidated Financial Statements and Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations for additional information about foreign currency transaction gains and losses, changes in foreign currency exchange rates, the impact of such changes on the increase in our revenues and operating margins, our use of foreign currency exchange derivatives, and our designation of certain portions of our Euro-denominated debt as a hedge of the foreign currency exposure of the net investment in certain Euro functional currency subsidiaries. We generally enter into foreign currency exchange derivatives to hedge our exposure to the impact of movements in foreign currency exchange rates on our transactional balances denominated in currencies other than the functional currency. We will continue to evaluate the use of derivative instruments in the future. We also designate certain portions of the aggregate principal value of our Euro-denominated debt as a hedge of the foreign currency exposure of the net investment in certain Euro functional currency subsidiaries. Foreign currency transaction gains or losses are dependent on the amount of net assets of the Euro functional currency subsidiaries, the amount of the Euro-denominated debt that is designated as a hedge, and fluctuations in foreign currency exchange rates.

See Notes 5 and 6 to our Consolidated Financial Statements for information about our investments in equity securities of publicly-traded companies and private companies. We are exposed to equity price risk as it relates to changes in fair values of these investments. Our investments in private companies are measured at cost less impairment, if any. Such investments are also required to be measured at fair value as of the date of certain observable transactions for the identical or a similar investment of the same issuer. A hypothetical 10% decrease in the fair values at December 31, 2023 and 2022 of our investments in equity securities of publicly-traded companies and private companies would have resulted in a loss, before tax, of approximately $45 million and $220 million, respectively, being recognized in net income.
