## Abstract

This document contains temporary regulations under section 1502 of the Internal Revenue Code (Code) that affect corporations filing consolidated returns. These regulations permit consolidated groups that acquire new members that were members of another consolidated group to elect in a year subsequent to the year of acquisition to waive all or part of the pre-acquisition portion of an extended carryback period under section 172 of the Code for certain losses attributable to the acquired members where there is a retroactive statutory extension of the NOL carryback period under section 172. These regulations respond to the enactment of section 2303 of the CARES Act, which retroactively extends the carryback period under section 172 for taxable years beginning after 2017 and before 2021.
