[1] As permitted under Section 40(b) of the Internal Revenue Code of 1986, as amended (the Code), producers of second-generation biofuels that are registered with the Internal Revenue Service (IRS) are eligible for an income tax credit of up to $1.01 per gallon of qualified biofuel that was produced and sold in the U.S. through December 31, 2024. We recorded a gross tax benefit in December 2024 related to these tax credits for the cellulosic ethanol produced by our Ethanol segment from 2020 through 2024.
