The carrying amounts of the investment in lease, net, the secured long-term note payable and the unsecured long-term note payable approximate fair value as of March 31, 2018 and December 31, 2017 because those financial instruments bear interest at rates that approximate current market rates for similar agreements with similar maturities and credit.
