Before Ken sold Ukyo's shares they were Ukyo's. So.. Ukyo has .0025BTC priority in Divs on those shares before Ken's 15 Million kick in. After Ken sold those shares whoever bought them now has the .0025BTC priority in Divs on those shares before Ken's 15 Million kick in.

Ken/ActM isn't losing money by selling Ukyo's shares for .0005. If anything he is gaining .0005BTC per share sold. He doesn't owe more. The only way Ken doesn't have to pay priority Divs on those shares is if he destroys them.

EDIT: Anyways forget about Ukyo's shares for just a minute. We have 9.8M other shares to worry about. Ken where are they at?
