"if they reissue new shares like they will more than likely do."
By definition, any company that enters into chapter 11 will have "old" stock that at some point will have no value. If/when they emerge from BK, they will and must issue new stock, because they emerge as a new entity. The only question is whether or not the legacy shareholders will be offered any % of the new company stock. Sometimes they are offered new stock on a 1:1 basis, sometimes they are offered at a ratio less than 1:1, and sometimes they are offered nothing.
Please provide any evidence you may have that legacy shareholders will not be offered anything for their old shares.
