Revenue from contracts with customers primarily consists of casino wagers, room sales, food and beverage transactions, rental income from the Company’s retail tenants and entertainment sales.

Casino gaming revenues are the aggregate of gaming wins and losses. The commissions rebated to premium players for cash discounts and other cash incentives to patrons related to gaming play are recorded as a reduction to casino gaming revenues. Gaming contracts include a performance obligation to honor the patron’s wager and typically include a performance obligation to provide a product or service to the patron on a complimentary basis to incentivize gaming or in exchange for points earned under the Company’s loyalty programs.

The Company generally enters into three types of slot and amusement device placement contracts as part of its distributed gaming business: space agreements, revenue share agreements and participation agreements. Under space agreements, the Company pays a fixed monthly rental fee for the right to install, maintain and operate the Company’s slots at a business location. Under these agreements, the Company recognizes all gaming revenue and records fixed monthly rental fees as gaming expenses. Under revenue share agreements, the Company pays the business location a percentage of the gaming revenue generated from the Company’s slots placed at the location and records that amount as an expense. With regard to both space and revenue share agreements, the Company holds the applicable gaming license to conduct gaming at the location (although revenue share locations are required to obtain separate regulatory approval to receive a percentage of the gaming revenue). Under participation agreements, the business location holds the applicable gaming license and retains a percentage of the gaming revenue that it generates from the Company’s slots which the Company records as an expense. In Montana, the Company’s slot and amusement device placement contracts are all participation agreements. In its distributed gaming business, the Company considers its customer to be the gaming player since the Company controls all aspects of the slot machines. Due to the maintaining of control of the services directly before they are transferred to the customer, the Company is considered to be the principal in these transactions and therefore records revenue on a gross basis.

For wagering contracts that include complimentary products and services provided by the Company to incentivize gaming, the Company allocates the stand-alone selling price of each product and service to the respective revenue type. Complimentary products or services provided under the Company's control and discretion that are supplied by third parties are recorded as an operating expense.

For wagering contracts that include products and services provided to a patron in exchange for points earned under the Company’s loyalty programs, Golden Rewards, ace|PLAY, Gold Mine Rewards and Rocky Gap Rewards Club, the Company allocates the estimated stand-alone selling price of the points earned to the loyalty program liability. The loyalty program liability is a deferral of revenue until redemption occurs under ASC 606. Upon redemption of loyalty program points for Company-owned products and services, the stand-alone selling price of each product or service is allocated to the respective revenue type. For redemptions of points with third parties, the redemption amount is deducted from the loyalty program liability and paid directly to the third party. Any discounts received by the Company from the third party in connection with this transaction are recorded to other revenue. The Company’s performance obligation related to its loyalty programs is generally completed within one year, as participants’ points expire after thirteen months of no activity.

After allocation to the other revenue types for products and services provided to patrons as part of a wagering contract, the residual amount is recorded to casino gaming revenue as soon as the wager is settled. As all wagers have similar characteristics, the Company accounts for its gaming contracts collectively on a portfolio basis. Gaming contracts are typically completed daily based on the outcome of the wagering transaction and include a distinct performance obligation to provide gaming activities.

Revenue from leases is primarily recorded to other revenues and is generated from base rents through long-term leases with retail tenants. Base rent, adjusted for contractual escalations, is recognized on a straight-lined basis over the term of the related lease. Overage rent is paid by a tenant when its sales exceed an agreed upon minimum amount and is not recognized by the Company until the threshold is met.

Food, beverage, and retail revenues are recorded at the time of sale. Room revenue is recorded at the time of occupancy. Sales taxes and surcharges collected from customers and remitted to governmental authorities are presented on a net basis.

The adoption of ASC 606 principally affected the presentation of promotional allowances and how the Company measured the liability associated with its loyalty programs. The promotional allowances line item was eliminated from the consolidated statement of operations with amounts being deducted from the respective revenue line items, and the cost of providing such complimentaries is no longer included in gaming expense. Additionally, the valuation of points associated with the Company’s loyalty programs was changed from cost to fair value, with the Company recording an increase to the loyalty point liability.

The Company elected to adopt the full retrospective method to apply the new guidance to each prior reporting period presented as if it had been in effect since January 1, 2016. The only cumulative effect of the adoption recognized was a decrease in retained earnings of $1.0 million on October 20, 2017 (no income tax effect), related to the loyalty program point liability of the business combination.

Adoption of the new standard did not have a significant impact on the Company’s previously reported net revenues, expenses, operating income, and net income. The impact of adoption of the new standard to previously reported selected financial statement information was as follows:
