RVXOT do I recall you looking into this in the past? There was a financing after the one where the RVX.WT's where issued that was priced around $4.00. It would make sense that a number of the WT's were exercised which would have put $$ in the company coffers at that time. That in turn would reduce the number of WT's still on the street. If that number is low enough it may not be worth the effort to extend the expiry date at all.
