(1)Level 1: Fair value calculated based on quoted prices in active markets.

(2)Level 2: Fair value based on (i) for marketable debt securities, quoted prices for similar or identical instruments in active or inactive markets, respectively, or (ii) for loans receivable, net, mortgage debt, and swaps, standardized pricing models in which significant inputs or value drivers are observable in active markets. For bank line of credit, commercial paper, and term loan, the carrying values are a reasonable estimate of fair value because the borrowings are primarily based on market interest rates and the Company’s credit rating.
