 rate risk, liquidity risk, or risk of default by investing in investment grade securities with maturities of four years or less. Our exposure to market risk is confined to investments in cash and cash equivalents, and marketable securities. As of December 31, 2024, we had unrestricted cash and cash equivalents and marketable securities of $453.6 million. 

We fully repaid the outstanding principal and interest on the 2023 Notes in April 2023. We borrowed funds pursuant to our Credit Line in connection with the payment of the 2023 Notes. We fully repaid the outstanding debt under the Credit Line in June 2023. In the future, we may borrow funds under the Credit Line. Variable rate borrowing, which may occur under the Credit Line, exposes us to interest rate risk as increases in interest rates would increase our borrowing costs.

Any borrowed funds pursuant to our Credit Line are subject to a collateral maintenance requirement. The Credit Line is secured primarily by our portfolio of marketable securities, which is primarily comprised of corporate and U.S. government agency and municipal debt securities and may fluctuate in value. The fluctuations may be driven by, among other things, changes in interest rates, economic conditions, and other financial conditions as well as idiosyncratic factors related to a security’s issuer. To the extent a fluctuation in value results in the value of the collateral decreasing below the required collateral maintenance requirements we may be required to promptly post additional collateral. Additionally, our Credit Line is an uncommitted facility that may be terminated by the lender at any time. During periods of rapidly changing interest rates, economic conditions or other financial conditions, the Credit Line may be terminated by the lender and/or the lender may declare that all borrowings thereunder are immediately due.

Our cash and cash equivalents consist primarily of cash held at banks and investments in highly liquid financial instruments with an original maturity of three months or less. Our marketable securities, which are reported at fair value, consist of investments in U.S. Treasury bills and notes; bank certificates of deposit; various U.S. governmental agency debt securities; and corporate and municipal debt securities. We place all investments with governmental, industrial, or financial institutions whose debt is rated as investment grade. We generally hold these securities to maturities of one to four years. Because of the relatively short period that we hold our investments and because we generally hold these securities to maturity, we do not believe that an increase in interest rates would have any significant impact on the realizable value of our
