Schedule of Derivative Instruments

Interest Rate Swaps

The Company has interest rate swap agreements outstanding with various counterparties which are centrally cleared through the CME. As explained in Note 1, the exchange of variation margin for CME cleared interest rate swaps is legally considered to be the settlement of the derivative itself as opposed to a pledge of collateral. Because the Company accounts for this daily exchange of variation margin for its CME cleared interest rate swaps as an increase or decrease to the carrying value of the related derivative asset or liability, the fair value of the interest rate swaps nets to $0 on the Company’s consolidated balance sheet. The Company had net settlement amounts of $(1,557) and $(9,265) in variation margin for its interest rate swaps as of March 31, 2020 and December 31, 2019, respectively.
