(1) Gaming operations revenue for the year ended December 31, 2021 benefited from $44 million U.K. fixed odds betting terminals (“FOBT”) recovery received from certain U.K. customers for value-added tax charged on FOBTs (“FOBT recovery”) related to a 2020 U.K. court ruling associated with overcharging of value-added tax for gaming operators that consequently reduced our net gaming revenues in those affected prior periods related to these customers and arrangements.
