On December 20, 2019, the AFTC, which had previously expired, was retroactively reinstated and extended beginning January 1, 2018 through December 31, 2020. The AFTC credit is equal to $0.50 per gasoline gallon equivalent of CNG that the Company sold as vehicle fuel, and $0.50 per diesel gallon of LNG that the Company sold as vehicle fuel in 2019 and 2020. Based on the service relationship with its customers, either the Company or its customers claims the credit.
