REVENUE RECOGNITION The Company recognizes revenue in accordance with Accounting Standards Codification No. 605, "Revenue Recognition" ("ASC-605") ASC-605 requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred; (3) the selling price is fixed and determinable; and (4) collectability is reasonably assured. Determination of criteria (3) and (4) are based on management's judgments regarding the fixed nature of the selling prices of the products delivered and the collectability of those amounts. Provisions for discounts and rebates to customers, estimated returns and allowances, and other adjustments are provided for in the same period the related sales are recorded. The Company will defer any revenue for which the product has not been delivered or is subject to refund until such time that the Company and the customer jointly determine that the product has been delivered or no refund will be required. The Company's revenues have been generated primarily through the sales of the Optimized Fuel Maximizer units and sublicense and distribution agreements related to our PawPal product and our pain relief products. The terms of these agreements generally consist solely of upfront, nonrefundable payments for licensing and distribution rights. Revenues from non-refundable licensing and distribution fees are recognized upon receipt of the payment if the license has stand-alone value and we do not have ongoing involvement or obligations. For the years ended June 30, 2018 and 2017, all sales and license payments met the above criteria or in the case of one contract, the only continuing involvement was to sell our products to the distributor at pricing that is consistent with market transactions, thereby allowing for the recognition of revenue for the licensing and distribution arrangements upon receipt. When non-refundable license fees do not meet this criteria, the license revenues are recognized over the expected period of performance. We periodically review for any expected period of substantial involvement under the agreements that provide for non-refundable up-front payments and license fees. If ever applicable, we will adjust the amortization periods when appropriate to reflect changes in assumptions relating to the duration of our expected involvement.
