Hi Cowboy,
It is clearly stated in our Terms that we reserve the right to make negative carry-overs. We really hardly ever apply it, as can be evidenced by the lack of complaints/remarks about this subject in our forum.
As to the threshold to apply this I can say that it is based on the performance of your players, both past and present. But there are simply too many factors that will go into whether or not an affiliate gets a negative carry over for me to say it is due to X performance during a given period of time in a given casino.
I apologize for any inconvenience this may have caused you and I thank you for your understanding.
Best Regards,
Nicolas Johnson
Assistant Affiliate Manager
