xoom, it's my understanding that what has been published is the number the BoD - at the time - with limited financial work and personnel and before Blackstone - was able to put forward.
A "floor" figure, if you will.
Fiduciary responsibilities keep them from saying things like "We might have $20b in NOLs" -- (just a made up number) -- and then have it turn out to be just $5b instead.
Imagine folks going nuts over that scenario instead. "But, but, but, the BoD said it was $20b -- now it's just $5b instead! The BoD must be incompetent to publish such erroneous information, off-with-their-heads..."
Depending on the plans, moving forward, there is not a singular number to put on the NOLs -- it all depends on how things end up being structured, etc.
So, the BoD, IMHO, did what was appropriate -- stated what was legitimately felt to be the NOLs at that moment in time.
If a better deal, and better way, and a higher value of NOLs can be created/justified and PLR'd by Blackstone -- then great.
