An August 11, 2020 article from WorldOil Magazine had the following headline: "Marathon Sets Up for \$1.1 Billion Tax Refund via Coronavirus Aid Law". The article goes on to indicate, "That measure included a tax provision that allows companies to immediately deduct net operating losses and apply them to previous returns for five years from 2018, 2019, and 2020 - instead of only applying those deductions to future years. The benefit is supercharged because deductions taken before the 2017 tax overhaul can be claimed at the 35% corporate tax rate instead of the current 21%."
