Item 3. Quantitative and Qualitative Disclosures About Market Risk
Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates and foreign currency exchange rates.
Interest Rate Risk
We had cash and cash equivalents of $170.1 million as of March 31, 2024, which consisted of investments in money market funds, cash in readily available checking accounts, and overnight repurchase investments.
As of March 31, 2024, we had outstanding principal debt of $255.1 million, which carries interest as defined in our Credit Agreement. Refer to Note 8 of the condensed consolidated financial statements in this Quarterly Report on Form 10-Q for additional details. We assessed our exposure to changes in interest rates by analyzing sensitivity to our operating results, assuming various changes in market interest rates. A hypothetical increase of one percentage point in the interest rate as of March 31, 2024 would increase our interest expense by approximately $2.5 million annually.
Inflation Risk
We are exposed to market risks related to inflation in personnel costs, third-party service providers, subcontracting costs, professional fees, and general overhead expenses. Although inflation has decreased from the relative highs experienced in 2022, if inflation pressure increases in severity, we may not be able to fully offset such higher costs through price increases and productivity initiatives. While we do not believe inflation has had a material impact on our results of operations to date, a continued high rate of inflation in the future may have an adverse effect on our ability to maintain operating costs and adversely affect our gross profit margin.
Foreign Currency Exchange Risk
Our reporting currency is the U.S. dollar. Due to our international operations, we have foreign currency risks related to revenue and operating expenses denominated in currencies other than the U.S. dollar, primarily the British pound sterling, Euro, Australian dollar, and Swiss franc. Our sales contracts are primarily denominated in the local currency of the customer making the purchase. In addition, portions of operating expenses are incurred outside the United States and are denominated in foreign currencies. An increase in the relative value of the U.S. dollar to other currencies will negatively affect revenue and other operating results as expressed in U.S. dollars. Based on a sensitivity analysis, a 10% change in the foreign currency exchange rates for the three months ended March 31, 2024 would have impacted our total revenue by approximately 3% and operating loss by approximately 4%. This calculation assumes all currencies change in the same direction and proportion relative to the U.S. dollar.
We have experienced, and will continue to experience, fluctuations in net loss as a result of transaction gains or losses related to remeasuring certain current asset and current liability balances denominated in currencies other than the functional currency of the entities in which they are recorded. We have not engaged in the hedging of foreign currency transactions to date, although we may choose to do so in the future.
