ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to a variety of market risks, including fluctuations in foreign currency exchange rates and interest rates affecting the return on our cash, cash equivalents, and marketable securities. Foreign Currency Exchange Risk As we expand internationally, our results of operations and cash flows will become increasingly subject to foreign exchange rate fluctuations. For the years ended December 31, 2023, 2022, and 2021, approximately 37%, 38% and 36%, respectively, of our total revenue was generated from customers located outside of the United States. Our expenses are generally denominated in the currencies in which our operations are located, which is primarily in the United States, with a portion of expenses incurred in Canada, Europe, Japan, and China. Our results of operations and cash flows are, therefore, subject to fluctuations due to changes in foreign exchange rates in Canadian dollars, Euros, British pounds, Swedish krona, Japanese yen, Chinese yuan, and other foreign currencies. Fluctuations in exchange rates could harm our business in the future. As of December 31, 2023, 2022, and 2021, the effect of a hypothetical 10% adverse change in exchange rates on foreign denominated cash and payables would not have been material in any annual period. A similar adverse change on foreign denominated receivables would decrease potential cash inflows by $0.8 million for the year ended December 31, 2023, and would not have been material for the years ended December 31, 2022 or 2021. To date, we have not entered into any foreign currency hedging contracts although we may do so in the future. Interest Rate Risk (As Restated) We had cash and cash equivalents of $174.4 million and marketable securities of $146.9 million as of December 31, 2023. We had cash and cash equivalents of $338.7 million as of December 31, 2022. All cash, cash equivalents, and marketable securities are held at large commercial banks. Marketable securities consisted entirely of highly rated debt securities including commercial paper, U.S. Treasuries, corporate notes and bonds, U.S. Government agency bonds, certificates of deposit, and similar types of debt securities. Due to the short-term nature and investment 34 Table of Contents grade quality of these investments, we do not believe we have material exposure to changes in interest rates. Additionally, if needed, we have the ability to hold our marketable securities until maturity (without giving effect to any future acquisitions or mergers) and we do not hold or issue financial instruments for trading purposes. Therefore, we do not expect our operating results or cash flows to be affected materially by a sudden change in market interest rates. Declines in interest rates, however, would reduce future investment income. If overall interest rates had decreased by a hypothetical 10%, our interest income would have decreased income by approximately $1.3 million during the year ended December 31, 2023, and it would not have had a material effect on income during the years ended December 31, 2022 and 2021.
