Fair Value of Financial Instruments

3.    Fair Value of Financial Instruments

At September 30, 2013 and 2012, the Company’s financial instruments included cash and cash equivalents, short-term investments in certificates of deposit, trade and other receivables, other current assets, accounts payable, other current liabilities, the Term Note and the Second Term Note. At September 30, 2013, the Company’s financial instruments also included the Third Term Note. Due to the short-term maturities of cash and cash equivalents, trade and other receivables, other current assets, accounts payables and other current liabilities, the carrying amounts approximate fair value at the respective balance sheet dates. The carrying value of the Company’s Term Note and Second Term Note approximate their fair value due to the fact that the interest rates on the Term Note and Second Term Note are reset each month based on the prevailing market interest rate. The Company’s Third Term Note approximates its fair value based on a comparison with the prevailing market interest rate. Due to the short-term maturities of the Company’s investments in certificates of deposit, the carrying amounts approximate fair value at the respective balance sheet dates. The fair values of the Company’s notes payable and investments in certificates of deposit are Level 2 measurements in the fair value hierarchy.
