However, judgment was necessary to interpret market data and develop estimated fair value. Cash and cash equivalents, receivables, accounts payable and accrued expenses and other liabilities are carried at amounts which reasonably approximate their fair values as of March 31, 2013 and December 31, 2012 due to the short term nature of these financial instruments. The Partnership’s long-term debt consists of notes payable, which are secured by specific equipment and are nonrecourse liabilities of the Partnership. The estimated fair value of this debt at June 30, 2013 and December 31, 2012 approximates the carrying value of these instruments, due to the interest rates on the debt approximating current market interest rates. The Partnership classifies the fair value of its notes payable within Level 2 of the valuation hierarchy based on the observable inputs used to estimate fair value.
