Because without this sentence one could not speak of a 'fire sale'
My 2 cents on:
Maybe the sum of money they got for EEZ 11 gives them the opportunity to continue despite a dry hole in 11A...
An indication could be the fact that there is a clause that ERHC will profit from oil in EEZ 11. Why the clause if ERHC very likely, probably, does not exist anymore, since finding oil is always a high risk? Also... I'm sure that if block 11 could be sold, that block 4 also could have been sold if they wanted, which could carry them through Chad for instance.
AND... above all, you forgot about someone: SEO, who can, if he wants, step in at ANY time to keep ERHC alive.
Remember, SEO is the guy that spends more on welfare in 1 year than on ERHC... just think about that.
