the "NOL" discussion has played out many times on this board. NOL's are a complicated subject and have VERY restrictive rules about how they can be used.
But assuming the NOL's had ANY actual and USABLE value at all the ONLY way they could have been exploited was if the company was purchased as a WHOLE and OPERATING entity.
That didn't happen.
The assets were liquidated. There is no way the NOL's can be used any longer once that happened.
