There are some flaws in whatth post.Non released shareholders can't be identified by estates now after 10 yrs.There is no way to identify them. Escrow markers were paid cash too in 2014 or 2013,i am not sure but a small cash amounts were distributed. Litigation proceed interests could get cash.Right to get a liquidating trust interest qualifies one to receive litigation proceeds interests.Litigation proceeds interests are not trust assets ie DCR.
