Item 3. Quantitative and Qualitative Disclosures About Market Risk.
We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest rate and market price sensitivities.
Interest Rate Risk
We had cash, cash equivalents and restricted cash and cash equivalents of $368.0 million as of March 31, 2025, which primarily consisted of deposits in checking and sweep accounts at financial institutions and money market funds. We also had short-term and long-term investments of $735.5 million as of March 31, 2025. The primary objective of our investment activities is to preserve capital to fund our operations. We also seek to maximize income from our investments without assuming significant risk. Because our investments are primarily short-term in duration and consist of U.S. government treasuries, U.S. government agency bonds and discount notes, and securities issued by institutions with investment-grade credit ratings mature prior to our expected need for liquidity, we believe that our exposure to interest rate risk is not significant, and one percent movement in market interest rates would not have a significant impact on the total value of our portfolio. We had no debt outstanding as of March 31, 2025.
Foreign Currency
The majority of our transactions occur in U.S. dollars. However, we do have certain transactions that are denominated in currencies other than the U.S. dollar. The functional currency of our foreign subsidiaries is the U.S. dollar. Monetary assets and liabilities of our foreign subsidiaries are translated into U.S. dollars at period end exchange rates and non-monetary assets and liabilities are translated to U.S. dollars using historical exchange rates. Revenue and expenses are translated at average rates throughout the respective periods. As of the date of this Quarterly Report on Form 10-Q, we are exposed to foreign currency risk primarily related to Euro, Swiss Franc and Australian dollar. Transaction gains and losses are included in other expense, net on the unaudited condensed consolidated statements of operations and were not material for the three months ended March 31, 2025 and 2024.
Equity Investment Risk
We hold ordinary shares of Brii Bio Parent, which we acquired in connection with our collaboration, option and license agreement. These equity securities are measured at fair value with any changes in fair value recognized in our unaudited condensed consolidated statements of operations. The fair value of these equity securities was approximately $10.7 million as of March 31, 2025. Changes in the fair value of these equity securities are impacted by the volatility of the stock market and changes in general economic conditions, among other factors. A hypothetical 10% increase or decrease in the stock price of these equity securities would increase or decrease their fair value as of March 31, 2025 by approximately $1.1 million.
