There were 100 apples, all worth £5 each
ADUG owned 78
Silver lake owned 18
Other people owned 4
Some more apples are made, so now there's about 104 apples
Instead of splitting the extra in the same way as above ie ADUG get 78% of them, SL 18%, others 4%
We are going to give ADUG about 76% of them, SL about 20% and others 4%
So now everyone owns more apples, but SL own a little bit more than they used to, and ADUG own slightly less
That swing would have been a little bit bigger had they not been NEW shares, as owning 76% of 104 is bigger than owning 78% of 100....just!
I appreciate this may have confused you even more, but there is no idiots guide to Accountancy, unfortunately!
