(2) During the month ended January 31, 2026, we finalized an agreement to monetize a subordinated seller financing note associated with property in La Jolla, California, that had an effective interest rate of 6.0% and a current annual interest rate of 2.9%. The agreement was structured as a modification and repayment of the note in January 2026, when we collected the $18.5 million balance included within Notes receivable within the Condensed Consolidated Balance Sheet as of December 31, 2025. During the three months ended March 31, 2025, we recognized amortization of discount on the seller financing note of $0.3 million, which was recorded as a component of Interest Income in our Condensed Consolidated Statements of Operations. We did not recognize any amortization of the discount during the month ended January 31, 2026.
