That’s the $5/share question! Tax attributes (incl. NOLs) are not with Lampert yet. They made it read like they are but I see a pretty big paragraph in the asset purchase agreement that says they need a tax counsel to weigh in and even with that they will still need the Service (ie the IRS) to opine. Remember Lampert said he is a betting man, and so if his lawyers told him there is some chance it goes through then he would have gone for it (which he did).
If he can’t get tax attributes by purchasing assets, then either he purchases the stock or he leaves them in SHLDQ and needs to throw a bone at the commons to preserve NOLs upon emerging from Chapter 11.
