Revenue	2. REVENUE Revenue recognition Our revenue is derived primarily from point of sale transactions executed over an e-commerce platform for weight loss, weight management, and other consumable health and nutritional products. Revenue is recognized upon receipt by customer and net of discounts, rebates, promotional adjustments, price adjustments, allocated consideration to loyalty programs and estimated returns. Revenue is recognized when control of the promised products are transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for transferring those products. When determining whether the customer has obtained control the products, we consider any future performance obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Our contracts have performance obligations to fulfill and deliver products from the point of sale transaction along with the related customer reward programs. Our performance obligations are satisfied at a point in time. Revenue from products transferred to customers at a point in time accounted for substantially all of our revenue for the three and six month periods ended June 30, 2018 and 2017, respectively. Revenue on these contracts is recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control upon receipt of products by our customers. Any consideration received prior to the fulfillment of the Company performance obligation is deferred and recognized as a liability. Sales returns Our return policy allows for customer returns within 30 days of purchase and upon our authorization. We adjust revenues for the products expected to be returned and a liability is recognized for expected refunds to customers. We estimate expected returns based on historical levels and project this experience into the future. Customer reward programs and sales incentives Our sales contracts may give customers the option to purchase additional products priced at a discount. Options to acquire additional products at a discount can come in many forms, such as customer reward programs and incentive offerings including pricing arrangements, and promotions. We reduce the transaction price for certain customer reward programs and incentive offerings including pricing arrangements, promotions, incentives that represent variable consideration and separate performance obligations. The Company accounts for sales rewards as a separate performance obligation of the transactions, and therefore allocates consideration between the initial sale of products and the customer reward program and incentive offering.

We considered the following factors in making this decision: the nature of business activities overlapping amongst previous defined sales channels, the management structure directly accountable to our chief operating decision maker for operating and administrative activities, and information presented to the Board of Directors and investors. We previously disclosed entity-wide disclosures for sales by channel: OPTAVIA, Medifast Direct, Franchise Medifast Weight Control Centers and Medifast Wholesale. Due to the interchangeable nature of these customers amongst sale channels, sales migration to OPTAVIA, and realignment of internal operations as discussed, our disclosures as of January 1, 2018 will not include revenues by sales channel.

Revenue recognition

Our revenue is derived primarily from point of sale transactions executed over an e-commerce platform for weight loss, weight management, and other consumable health and nutritional products. Revenue is recognized upon receipt by customer and net of discounts, rebates, promotional adjustments, price adjustments, allocated consideration to loyalty programs and estimated returns.

Revenue is recognized when control of the promised products are transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for transferring those products. When determining whether the customer has obtained control the products, we consider any future performance obligations.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606.
