REVENUE AND PRODUCT COSTS	The Company enters into contracts that include various combinations of products, accessories. software and services, each of which are generally distinct and are accounted for as separate performance obligations. A performance obligation is a promise in a contract to transfer a distinct good or service to a customer, and is the unit of account in Topic 606. For contracts with a single performance obligation, the entire transaction price is allocated to the single performance obligation. For contracts with multiple performance obligations, the Company allocates the contract transaction price to each performance obligation using the Company’s estimate of the standalone selling price (“SSP”) of each distinct good or service in a contract. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price considering available information such as market conditions and internally approved pricing guidelines related to the performance obligations. Most of the Company’s products and accessories are sold through domestic and international distributors. Performance obligations to deliver products and accessories are generally satisfied at the point in time the Company ships the product, as this is when the customer obtains control of the asset under our standard terms and conditions. Periodically, certain customers request bill and hold transactions for future delivery as scheduled and designated by them. In such cases, revenue is not recognized until after control, title and risk of ownership has transferred which is generally when the customer has requested such transaction under normal billing and payment terms and has been notified that the product (i) has been completed according to customer specifications, (ii) has passed quality control inspections, and (iii) has been tagged and packed for shipment, separated from other inventory and ready for physical transfer to the customer. The value associated with custodial storage services is deemed immaterial in the context of such contracts and in total, and accordingly, none of the transaction price is allocated to such service. The Company has elected to recognize shipping costs as an expense in cost of revenue when control has transferred to the customer. Time-based virtual reality system contracts generally include setup, training and the use of software and hardware for a fixed term, generally one to five years and support and upgrade services during the same period. The Company does not sell time-based arrangements without setup, training and support services and therefore revenues for the entire arrangement are recognized on a straight-line basis over the term. When hardware is bundled and not sold separately the Company allocates the contract transaction price to each performance obligation using the SSP of each distinct good and service in the contract. The timing of revenue recognition may differ from the timing of invoicing to customers. The Company generally has an unconditional right to consideration when customers are invoiced and a receivable is recorded. A contract asset is recognized when revenue is recognized prior to invoicing, or a contract liability (deferred revenue) when revenue will be recognized subsequent to invoicing. At December 31, 2020 the Company’s deferred revenue totaled $16,015, of which $14,125 related to virtual reality training and $1,890 related to extended warranties. At December 31, 2019 the Company had deferred revenue of $2,684 related to future training contracted as part of a sale. The Company may also receive consideration, per terms of a contract, from customers prior to transferring goods to the customer. The Company records customer deposits as a contract liability. The Company recognizes an asset if there are incremental costs of obtaining a contract with a customer such as commissions. These costs are ascribed to or allocated to the underlying performance obligations in the contract and amortized consistent with the recognition timing of the revenue for any such underlying performance obligations. The Company had no such assets at December 31, 2020 and December 31, 2019. The Company will apply the practical expedient to expense any sales commissions related to performance obligations with an amortization of one year or less when incurred within selling, general and administrative expense. Estimated costs for the Company’s standard one-year warranty are charged to cost of products sold when revenue is recorded for the related product. Royalties are also charged to cost of products sold.
