338(h)(10) Election for Some But Not All Targets
A section 338(h)(10) election can be made for some target corporations in a chain but not others. Where the election is made, the selling group recognizes no gain or loss on the stock sale and the target is treated as selling its assets; where it is not made, the seller must recognize gain or loss on the deemed sale of that subsidiary’s stock.
