... because when someone refers to equity and change of ownership of (approx) 5% rule, they refer to equity in the holding company, NOT CTs., hence the lock up of equity in the holding company in to 1 share.
Lock up = no change in ownership.
CTs has nothing to do with that 1 share because they are considered debt, not equity.
If CTs were considered equity, then they would have been locked up to.
