(1)All of the Company’s interest rate swaps were cleared through a central clearing house. The Company exchanged variation margin for swaps based upon daily changes in fair value. As a result of amendments to rules governing certain central clearing activities, the exchange of variation margin is treated as a legal settlement of the exposure under the swap contract. Previously, such payments were treated as cash collateral pledged against the exposure under the swap contract. Accordingly, the Company accounted for the receipt or payment of variation margin as a direct reduction to or increase of the carrying value of the interest rate swap asset or liability on the Company’s consolidated balance sheets. Includes $29.0 million of derivative liabilities netted against a variation margin of $44.8 million at December 31, 2019.
