Revenue Recognition Technology Interactive Panels and Related Products The Company derives revenue from the sale of interactive panels and other related products. Sales of these panels may also include optional equipment, accessories and services (installation, training and other services, maintenance and warranty services). Product sales and installation revenue are recognized when all of the following criteria have been met: (1) products have been shipped or customers have purchased and accepted title to the goods; service revenue for installation of products sold is recognized as the installation services are performed, (2) persuasive evidence of an arrangement exists, (3) the price to the customer is fixed, and (4) collectability is reasonably assured. Deferred revenue consists of customer deposits and advance billings of the Company's products where sales have not yet been recognized. Shipping and handling costs billed to customers are included in revenue in the accompanying statements of operations. Costs incurred by the Company associated with shipping and handling are included in cost of sales in the accompanying statements of operations. Sales are recorded net of sales returns and discounts, and sales are presented net of sales-related taxes. Because of the nature and quality of the Company's products, the Company provides for the estimated costs of warranties at the time revenue is recognized for a period of five years after purchase as a secondary warranty. The manufacturer also provides a warranty against certain manufacturing and other defects. As of June 30, 2019 and 2018, the Company accrued $82,350 and $1,350, respectively, for estimated product warranty claims, which is included in accrued expenses in the accompanying consolidated balance sheets. The accrued warranty costs are based primarily on historical warranty claims as well as current repair costs. There was $87,374 and $1,350 of warranty expenses for the year ended June 30, 2019 and the three months ended June 30, 2018, respectively. There was $1,350 of warranty expense during the year ended March 31, 2018. The Company is negotiating a warranty settlement with one of its manufacturers. At June 30, 2019, the Company accrued $209,316 payable to this manufacturer to be paid over 24 months. Product sales resulting from fixed-price contracts involve a signed contract for a fixed price or a binding purchase order to provide the Company's interactive panels and accessories. Contract arrangements exclude a right of return for delivered items. Product sales resulting from fixed-price contracts are generated from multiple-element arrangements that require separate units of accounting and estimates regarding the fair value of individual elements. The Company has determined that its multiple-element arrangements that qualify as separate units of accounting are (1) product sales and (2) installation and related services. There is objective and reliable evidence of fair value for both the product sales and installation services and allocation of arrangement consideration for each of these units is based on their relative fair values. Each of these elements represent individual units of accounting, as the delivered item has value to a customer on a stand-alone basis. The Company's products can be sold on a stand-alone basis to customers which provides objective evidence of the fair value of the product portion of the multi-element contract, and thus represents the Company's best estimate of selling price. The fair value of installation services is separately calculated using expected costs of installation services. Many times, the value of installation services is calculated using price quotations from subcontractors to the Company who perform installation services on a stand-alone basis. The Company sells equipment with embedded software to its customers. The embedded software is not sold separately, and it is not a significant focus of the Company's marketing efforts. The Company does not provide post-contract customer support specific to the software or incur significant costs that are within the scope of FASB guidance on accounting for software to be leased or sold. Additionally, the functionality that the software provides is marketed as part of the overall product. The software embedded in the equipment is incidental to the equipment as a whole. Entertainment Theater Ticket Sales and Concessions Revenues are generated principally through admissions and concessions sales with proceeds received in cash or via credit card at the point of sale.
