Negative carryover
A RevShare clause that carries a losing month forward: when your players win more than they lose, the negative balance comes out of future earnings. With no negative carryover, the balance resets to $0 every month.
Also called: NCO, negative balance carryover, negative carry forward, carryover.
Hypothetically, your players produce minus $3,000 of NGR in March, plus $2,000 in April and plus $4,000 in May, on 40% RevShare. With carryover, April pays nothing and leaves minus $1,000; May pays 40% of $3,000, which is $1,200. Without carryover, March is reset to $0, April pays $800 and May $1,600. The same players earn you $2,400 instead of $1,200.
Carryover exists because casinos do lose money to lucky players and do not want to pay commission on players who cost them money. The difference between a fair version and a harsh one is scope. Read where the negative lives: per brand or pooled across every brand you promote, per player or across your whole account, unlimited or capped in time or amount. Some programs apply it only above a set loss.
The quiet risk is the account that never climbs out. A single big winner can bury months of normal play, and if you stop sending traffic there is nothing left to pay the hole down. No negative carryover is worth asking for, and often worth accepting a lower percentage.
