We maintain a portfolio of investments in a variety of fixed and variable debt rate securities, including U.S. Treasuries, U.S. government sponsored entities, corporate debt, asset-backed securities and others. As of June 30, 2026, the fair value of investments in marketable debt securities, available-for-sale was $191.7 million. The primary objective of our investment activity is to maintain the safety of principal and to provide for future liquidity requirements while maximizing yields without significantly increasing risk. While some investments may be securities of companies in foreign countries, all investments are denominated and payable in U.S. Dollars. We do not enter into investments for trading or speculative purposes. While our intent is not to sell these investment securities prior to their stated maturities, we may choose to sell any of the securities for strategic reasons including, but not limited to, anticipated capital requirements, anticipation of credit deterioration, duration management, yield management and because a security no longer meets the criteria of our investment policy. We do not use derivatives or similar instruments to manage our interest rate risk. We seek to invest in high quality investments. The weighted average credit rating of our portfolio investments (exclusive of cash, cash equivalents, and restricted cash) was A+ as of June 30, 2026. Maturities are maintained consistent with our short-, medium- and long-term liquidity objectives. Currently, our portfolio of investments predominantly consists of fixed interest rate debt securities; however, a portion of our investment portfolio may consist of variable interest rate debt securities. Our investments in fixed interest rate debt securities are subject to various market risks. Changes in prevailing interest rates may adversely or positively impact their fair market value should interest rates generally rise or fall. Accordingly, we also may have interest rate risk with variable interest rate debt securities as the income produced may decrease if interest rates fall. Contraction in market liquidity may adversely affect the value of portions of our portfolio and affect our ability to sell securities in the time frames required and at acceptable prices. Uncertainty in future market conditions may raise market participants’ 43 expectations of returns, thus impacting the value of securities in our portfolio as well. The following table sets forth the impact on the fair value of our investments as of June 30, 2026 from changes in interest rates based on the weighted average duration of the debt securities in our portfolio (in thousands): Change in Interest Rates Approximate Change in Fair Value of Investments Increase (Decrease) 2% Decrease $ 5,664 1% Decrease $ 2,926 1% Increase $ (3,113) 2% Increase $ (6,414) Due to the nature of our business and the manner in which we conduct our operations, we believe we do not face any material interest rate risk with respect to other assets and liabilities, equity price risk or other market risks. The functional currency of our Canadian operations is the Canadian dollar. We are exposed to foreign currency exchange rate risk for the settlement of transactions of the Canadian operations as well as unrealized translation adjustments. Historically foreign exchange rate risk has not been material.
