(18) Disclosures About Fair Value of Financial Instruments

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities are reasonable estimates of fair value because of the short-term maturities of these instruments. The fair values of loans receivable, bank line of credit, term loan, mortgage debt and other debt are based on rates currently prevailing for similar instruments with similar maturities. The fair values of interest-rate and currency swap contracts as well as common stock warrants are determined based on observable and unobservable market assumptions using standardized pricing models. The fair values of senior unsecured notes and marketable equity and debt securities are determined utilizing market quotes.
