If WMIH has 6b in NOLs, that equates to around 2.1b in actual tax savings (at best) using a 35% tax bracket. This is an immediate value. Figuring it will take several years to create 6b in profits to shelter from taxes, you must figure the present value of those NOLs. Now, you are down to about 1.4b or even less. Next, nobody (and I mean NOBODY) is going to pay full value for those NOLs - otherwise, why buy them. Figuring on a 50/50 value sharing plan, that would mean those 6b in NOLs are really worth, maybe, 700m. If you can figure on the rest of WMIH being worth another 100m, that gives, what looks like the BEST CASE SCENARIO, a value of 800m for 200m shares outstanding. This would mean $4 per share and not your dream number of $15 per share.
Now, this $4 could actually be more because stock price would be valued based on value of WMIH and its future profits based on the merger/acquisition and could produce a higher market valuation that may be several dollars higher.
Anyway, I have been here since before the seizure and you are completely wrong with your numbers. Don't forget another big problem. WMIH has to create large profits via merger/acquisition that still allow use of those NOLs. That, in itself, is another large hill to climb which is why my premise above is likely the best case scenario.
