Revenue Recognition We record revenue based on a five -step model which includes: ( 1 ) identifying a contract with a customer; ( 2 ) identifying the performance obligations in the contract; ( 3 ) determining the transaction price; ( 4 ) allocating the transaction price among the performance obligations; and ( 5 ) recognizing revenue as each of the various performance obligations are satisfied. Revenue is measured as the net amount of consideration expected to be received in exchange for fulfilling one or more performance obligations. We identify purchase orders from customers as contracts. The amount of consideration expected to be received and revenue recognized includes estimates of variable consideration, including estimates for early payment discounts and volume rebates. Such estimates are calculated using historical averages adjusted for any expected changes due to current business conditions and experience. We review and update these estimates at the end of each reporting period and the impact of any adjustments is recognized in the period the adjustments are identified. In assessing whether collection of consideration from a customer is probable, we consider both the customer's ability and intent to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, which is typically 30 days from the invoice date. Invoices are generally issued on the date of transfer of control of the products ordered to the customer. Revenue is recognized at the point in time that each of our performance obligation is fulfilled, and control of the ordered products is transferred to the customer. This transfer occurs when the product is shipped, or in some cases, when the product is delivered to the customer. We provide early payment discounts to certain customers. Based on historical payment trends, we expect that these customers will take advantage of these early payment discounts. The cost of these discounts is reported as a reduction to the transaction price. If the actual discounts differ from those estimated, the difference is also reported as a change in the transaction price. Except for product defects, no right of return exists on the sale of our products. We estimate returns based on historical experience and recognize a returns liability for any estimated returns. As of June 30, 2020, we have no known returns liability. On August 7, 2017, we entered into three agreements (Agreements), with The Juice Plus+ Company LLC (Juice Plus+). The Agreements are an Exclusive Manufacturing Agreement, a Restricted Stock Award Agreement, and an Irrevocable Proxy. Pursuant to the Exclusive Manufacturing Agreement, Juice Plus+ has granted us exclusive rights to manufacture and supply them with certain of their products within 24 countries where Juice Plus+ currently sells those products. Pursuant to the Restricted Stock Award Agreement, NAI granted 500,000 shares of NAI common stock to Juice Plus+, (the Shares), and Juice Plus+ agreed the Shares are subject to certain restrictions and risk of forfeiture. Pursuant to the Irrevocable Proxy, Juice Plus+ also granted the NAI Board of Directors the right to vote the Shares that remain subject to risk of forfeiture. Each of the Agreements is for a term of 5 years, and each may be terminated by either party only upon the occurrence of specified events. On March 31, 2019, we amended our original agreements with Juice Plus+ and extended the term of the Exclusive Manufacturing Agreement through August 6, 2025. In addition, pursuant to that Amended and Restated Exclusive Manufacturing Agreement, Juice Plus+ returned 400,000 shares of restricted common stock in exchange for an annual cash sales discount. The expense associated with the return of those shares and the related cash discount granted to Juice Plus+ are each recorded as a reduction to sales. As a result of the amendment to the Exclusive Manufacturing Agreement, we made a one -time adjustment to reverse the expense associated with unvested shares that were returned as a result of the Amended and Restated Exclusive Manufacturing Agreement. Amounts associated with the new cash discount began to be recorded in our fourth quarter of fiscal 2019 and will be amortized ratably over the remaining life of the extended agreement based on the full value of the cash discount expected to be given over the same period. We recorded no Non-Cash Sales Discount and $1.6 million of Cash Sales Discount for the year ended June 30, 2020, which was recorded as a reduction to net sales. We recorded $82,000 of Non-Cash Sales Discount and $395,000 of Cash Sales Discount during the year ended June 30, 2019, with such amounts recorded as a reduction to net sales. We currently own certain U.S. patents, and each patent's corresponding foreign patent applications. All of these patents and patent rights relate to the ingredient known as beta-alanine marketed and sold under the CarnoSyn and SR CarnoSyn trade names. We recorded beta-alanine raw material sales and royalty and licensing income as a component of revenue in the amount of $12.6 million during fiscal 2020 and $16.7 million during fiscal 2019. These royalty income and raw material sale amounts resulted in royalty expense paid to the original patent holders from whom NAI acquired its patents and patent rights. We recognized royalty expense as a component of cost of goods sold in the amount of $544,000 during fiscal 2020 and $686,000 during fiscal 2019.
