The following tables present our financial assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value.

The carrying amount of cash and cash equivalents including money market funds, short-term investments, accounts receivable, other receivables, accounts payable and accrued expenses approximates fair value due to the short terms to maturity of these instruments. The carrying amount of loans payable approximates fair value as the variable interest rates on the Company’s indebtedness approximate current market rates. Foreign currency forward exchange contracts are valued based on quotations from financial institutions and the value of interest rate swaps are the discounted net present value of the swaps using third party quotes from financial institutions.
