Investment Risk

We are exposed to investment risks related to changes in the underlying financial condition and credit capacity of certain of our investments. As of June 30, 2024, we had $575.0 million of investments in debt securities, of which $229.7 million were long-term. In addition, we had $123.6 million of investments in equity instruments of public and private companies. Should these companies experience a decline in financial performance, financial condition or credit capacity, or fail to meet certain development milestones, a decline in the investments' value may occur, resulting in unrealized or realized losses. See Note 5 to the Consolidated Condensed Financial Statements for additional information.
