Revenue Recognition On January 1, 2018, the Company adopted ASC 606 Revenue from Contracts with Customers, as amended regarding revenue from contracts with customers using the modified retrospective approach, which was applied to all contracts with Customers. Under the new standard an entity is required to recognize revenue to depict the transfer of promised goods to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods. There was no cumulative financial statement effect of initially applying the new revenue standard because an analysis of our contracts supported the recognition of revenue consistent with our historical approach. In accordance with the modified retrospective approach, the comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company does not expect the adoption of the new revenue standard to have a material impact on the Companys revenues or net income on an ongoing basis. The Companys revenues are primarily derived from consideration paid by customers for tangible goods. The Company analyzes its different goods by segment to determine the appropriate basis for revenue recognition, as described below. Revenue is not generated from sources other than contracts with customers and revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. There are no material upfront costs for operations that are incurred from contracts with customers. Our rights to payments for goods transferred to customers are conditional only on the passage of time and not on any other criteria. Payment terms and conditions vary by contract, although terms generally include a requirement of payment within 30 to 75 days. For 2017 the Company recognized revenue in accordance with Staff Accounting Bulletin No. 104, Revenue Recognition. The Company recognizes revenue when products are shipped and/or the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists, and the sales price is fixed or determinable. For 2018 and 2017, the Company recognized certain revenues under a bill and hold arrangement with two of its large customers. For any requested bill and hold arrangement, the Company made an evaluation as to whether the bill and hold arrangement qualified for revenue recognition. The customer would initiate the request for the bill and hold arrangement. The customer must have made its request in writing in addition to their fixed commitment to purchase the item. The risk of ownership has passed to the customer, payment terms were not modified and payment would be made if the goods had shipped. The Company had approximately $89,000 and $619,000 of net sales that were billed but not shipped under such bill and hold arrangements as of December 31, 2018 and 2017, respectively. Payments received in advance from customers are recorded as deferred revenue until earned, at which time revenue is recognized. The Terms and Conditions contained in our customer purchase orders often provide for liquidated damages in the event that a stop work order is issued prior to the final delivery. The Company utilizes a Returned Merchandise Authorization or RMA process for determining whether to accept returned products. Customer requests to return products are reviewed by the contracts department and if the request is approved, a credit is issued upon receipt of the product. Net sales represent gross sales less returns and allowances.
