Revenue Recognition and Promotional Allowances The Company recognizes revenues at the time persuasive evidence of an arrangement exists, the service is provided or the retail goods are sold, prices are fixed or determinable and collection is reasonably assured. Casino revenues are measured by the aggregate net difference between gaming wins and losses, with liabilities recognized for funds deposited by customers before gaming play occurs and for chips in the customers' possession. Cash discounts, other cash incentives related to casino play and commissions rebated through games promoters to customers are recorded as a reduction to casino revenues. Rooms, food and beverage, entertainment and other operating revenues are recognized when services are performed. Entertainment, retail and other revenue includes rental income, which is recognized on a time proportion basis over the lease term. Contingent rental income is recognized when the right to receive such rental income is established according to the lease agreements. Advance deposits on rooms and advance ticket sales are recorded as customer deposits until services are provided to the customer. Revenues are recognized net of certain sales incentives, which are required to be recorded as a reduction of revenue; consequently, the Company's casino revenues are reduced by discounts, commissions and points earned by customers from the Company's loyalty programs. The retail value of accommodations, food and beverage, and other services furnished to guests without charge is included in gross revenues. Such amounts are then deducted as promotional allowances.
