Yes, the number of shares actually registered doesn't change, yes there is a legal transfer, and yes the number of voting entitlements doesn't change. This argument has nothing to do with any of those things and it has nothing to do with whether anyone makes a profit or loss. It is about the number of shares
effectively issued
on the main market which does increase as I carefully explained. Please re-read comment #
