What is monthly ‘NGR’ net generated revenue and how is it calculated?

To calculate a players net revenue in the sportsbook, casino and racebook, we take the sum of gross revenue generated, wagers won/lost and then deduct from the total any money that was added to account as a bonus / incentive as well as a percentage of fees for processing. The figure that remains in considered the players NGR (net generated revenue) on which commissions are based.
