Gotta get rid of that negative carryover. Not many affiliates are going to sign up to a new casino with a negative carryover. That is just a way to lose affiliates.
For example, if you were an affiliate and had a winner win $20k – you now have a huge negative. You will have to have players make up for that in the following months. Why keep sending players? I would prefer to send a player to a place where I have NOTHING to make up. 
You should get rid of that term.
