(a)The Company estimates the fair value of financial instruments using a discounted cash flow model. This model incorporates assumptions such as current market rates and, where applicable, the credit quality of the borrower or tenant. In addition, the Company evaluates the value of the underlying collateral, considering factors such as collateral quality, borrower creditworthiness, time to maturity, and prevailing market conditions. These fair value estimates exclude unamortized discounts and deferred loan costs. As of the reporting date, the estimated market interest rates used in the valuation ranged from 3.93% to 13.11% for the Company’s notes receivable and City Point Loan, and from 5.27% to 7.70% for the Company’s property mortgage loans and other notes payable, depending on the specific characteristics of each loan.

(b)Includes the Operating Partnership’s cost-method investment in Fifth Wall (Note 4).

(c)The Company estimates the fair value of its unsecured notes payable and unsecured line of credit using quoted market prices in active or brokered markets, when available. In instances where observable market prices are not available due to limited or no trading activity, the Company estimates fair value using a discounted cash flow model. This model incorporates a rate that reflects the average yield of comparable instruments issued by market participants with similar credit risk profiles.
