Federal and state NOLs are being carried forward to offset current and future taxable income.

(b)For the three and six months ended June 30, 2022 and 2021, the federal income tax benefit is primarily due to production tax credits.

(c)For the three and six months ended June 30, 2022, the state benefit includes the impact of deferred repricing as a result of the New Energy acquisition.
