[1] Loans payable consist primarily of notes payable to various domestic and international financial institutions and it is not practicable to aggregate these notes and calculate a quarterly weighted-average interest rate.
[2] The weighted-average interest rate, inclusive of all brokerage fees, was 2.19 percent and 1.56 percent at September 30, 2018 and December 31, 2017, respectively.
[3] The fair value of debt is derived from Level 2 inputs.
