Under the Fair Value Option subsection of Accounting Standards Codification Subtopic 825-10, Financial Instruments – Overall, the Company has the irrevocable option to report most financial assets and liabilities at fair value on an instrument-by-instrument basis with changes in fair value reported in earnings. The Company has elected to report the related party note it issued to Agenus on February 12, 2024 (the “Note”) at fair value. The fair value of the Note is determined on a scenario based present value methodology. The outstanding principal amount of the Note was $5.0 million at June 30, 2024.
