Income Tax Disclosure [Abstract]
Income Taxes	Note 16—Income Taxes The provision for income taxes for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, a cumulative adjustment is recorded. The Company’s income tax expense was $0.1 million for each of the three months ended June 30, 2019 and 2020, and $0.1 million and $0.2 million for the six months ended June 30, 2019 and 2020, respectively. Tax expense for all periods consists of taxes due on the Company’s U.S. and foreign operations. The effective tax rates for the three and six months ended June 30, 2019 and 2020 are different from the federal statutory tax rate primarily due to losses for which no tax benefit has been recognized. The Company increased its liability for unrecognized tax benefits in the six months ended June 30, 2020 by $1.0 million. This increase is the portion of AFTC revenue recognized in the period attributed to the federal fuel tax the Company collected from its customers during the six months ended June 30, 2020. The net interest incurred was immaterial for both the six months ended June 30, 2019 and 2020.

Note 16—Income Taxes

The provision for income taxes for interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates the estimate of the annual effective tax rate, and if the estimated tax rate changes, a cumulative adjustment is recorded.

The Company’s income tax expense was $0.1 million for each of the three months ended June 30, 2019 and 2020, and $0.1 million and $0.2 million for the six months ended June 30, 2019 and 2020, respectively. Tax expense for all periods consists of taxes due on the Company’s U.S. and foreign operations. The effective tax rates for the three and six months ended June 30, 2019 and 2020 are different from the federal statutory tax rate primarily due to losses for which no tax benefit has been recognized.

The Company increased its liability for unrecognized tax benefits in the six months ended June 30, 2020 by $1.0 million. This increase is the portion of AFTC revenue recognized in the period attributed to the federal fuel tax the Company collected from its customers during the six months ended June 30, 2020. The net interest incurred was immaterial for both the six months ended June 30, 2019 and 2020.
