## Abstract

This document contains final regulations 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 the carryback period for certain losses attributable to the acquired members where there is a retroactive statutory extension of the net operating loss (NOL) carryback period. This document finalizes certain provisions in proposed regulations that were published on July 8, 2020, and removes temporary regulations published on the same date.
