LOL. You said that you can receive $$$$ for the write-off. Not true. Yes it's a write-off along with the other $37BB they already have in NOL's. But those are worthless for a potential acquiring company (see article below). This is just another pump by BOP plain and simple.
You can't receive $$$$ back from the IRS unless you realized the gain and paid taxes on it. To realize a gain, they would have had to sell shares to another investor at a profit. They did not do this. They have always owned 100% of the sub (i.e. never sold a share to another investor). Sorry but there's no gain to equity here no matter how you spin it.
