Revenue Recognition Effective August 1, 2018, we adopted the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC), Topic 606, Revenue from Contracts with Customers (Topic 606). Under Topic 606, revenue is recognized at an amount that reflects the consideration to which we expect to be entitled in exchange for transferring goods or services to a customer. This principle is applied using the following 5-step process: 1. Identify the contract with the customer 2. Identify the performance obligations in the contract 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations in the contract 5. Recognize revenue when (or as) each performance obligation is satisfied Under Topic 606, we recognize revenue when we satisfy a performance obligation by transferring control of the promised goods or services to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our technology platform is based on patented stabilized ionic silver, and our initial products contain silver dihydrogen citrate, or SDC. SDC is a broad-spectrum, non-toxic antimicrobial agent, which offers 24-hour residual protection and formulates well with other compounds. We sell various configurations and dilutions of SDC direct to customers and through distributors. We currently offer PURE Hard Surface as a food contact surface sanitizer and disinfectant to restaurant chains, food processors and food transportation companies. We also offer PURE Control as a direct food contact processing aid. Contract terms for unit price, quantity, shipping and payment are governed by sales agreements and purchase orders which we consider to be a customers contract in all cases. The unit price is considered the observable stand-alone selling price for the arrangements. Any promotional or sales discounts are applied evenly to the units sold for purposes of calculating standalone selling price. Product sales generally consist of a single performance obligation that we satisfy at a point in time. We recognize product revenue when the following events have occurred: (a) we have transferred physical possession of the products, (b) we have a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. Our direct customer and distributer sales are invoiced based on received purchase orders. Our payment terms on invoiced direct customer and distributor sales range between 30 and 90 days after we satisfy our performance obligation. The majority of our customers are on 30 day payment terms. We currently offer no right of return on invoiced sales and maintain no allowance for sales returns. Shipping and handling are treated as activities to fulfill promises to customers and any amounts billed to a customer, if applicable, represent revenues earned for the goods provided. Costs related to such shipping and handling billings are classified as cost of sales. We do not have significant categories of revenue that may impact how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. Variable Consideration We record revenue from customers in an amount that reflects the transaction price we expect to be entitled to after transferring control of those goods or services. From time to time, we offer sales promotions on our products such as discounts. Variable consideration is estimated at contract inception only to the extent that it is probable that a significant reversal of revenue will not occur. Practical Expedient We elected a practical expedient to expense sales commissions when the commissions are incurred because the amortization period would have been one year or less. These costs are recorded as Selling, general and administrative expense on our Consolidated Statements of Operations.
