My guess ... likely cheaper simply to buy enough shares each day to get a close @ or> $0.01.
If 250K shares/day required, @ $0.01, only $50k/month (20 trading days). Heck, just can Cliff. The other question is, what is benefit to management/directors to keep this dawg visible on any exchange? Then, for how long?
Seems to me, for sure, the shell itself has value to anyone from honest entrepeneurs needing an entity into which to merge all the way to consumate thieves . This stems from already being set up, vetted, publically traded, SEC-compliant, etc., etc.
For insight into my views on which end of the above spectrum PTSC execs/dirs lie, take a quick look at directors, sp history of Peregrine Pharma. It, too, has a potentially valuable asset.
Ahhh, the joys of a near-penny stock.
