in one end and out the other

Can someone please explain how CVI places 18.5% of Canzar / ADH into Fortitude and loses 22% of Fortitude as a prize for doing so. Ahhh. don't bother.
...........................

August : CityView owns 24,646,403 Fortitude shares,
out of a total issued capital of 54,832,103
Shares (approximately 45%).

September : the principal shareholders of
ADH merged their shares with Fortitude. CityView
has the right to transfer its 18.5% holding in ADH to
Fortitude on similar terms prior to December 31, 2009.

When CityView merges its shareholdings, it will own
75,088,849 Fortitude shares representing 22.93%
of the total issued capital of Fortitude
