Through fiscal 2018, in accordance with our historical accounting policies for revenue recognition, we recognized revenue upon transfer of title and risk of loss, or in the case of toll processing revenue, upon delivery of the goods, provided persuasive evidence of an arrangement existed, pricing was fixed or determinable and collectability was reasonably assured. Through charges to net sales, provisions were made for returns & allowances, customer rebates and sales discounts based on past experience, specific agreements, and anticipated levels of customer activity.

On June 1, 2018, we adopted new accounting guidance that replaces most existing revenue recognition accounting guidance under U.S. GAAP, Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) (“Topic 606”). The new accounting guidance was adopted using the modified retrospective approach as applied to customer contracts that were not complete at the date of adoption, with the cumulative effect recognized in retained earnings. Comparative financial information for reporting periods beginning prior to June 1, 2018, has not been restated and continues to be reported under the previous accounting guidance. The cumulative effect adjustment resulted from a change in the pattern of recognition for our toll processing revenue stream and certain contracts within the oil & gas equipment revenue stream, which previously were accounted for as point in time and now will be accounted for over time.

The following table outlines the cumulative effect of adopting the new revenue recognition guidance:

Under the new accounting guidance, we recognize revenue upon transfer of control of promised goods or services to customers in an amount that reflects the consideration we expect to receive for those goods or services, including any variable consideration.

Shipping and handling costs charged to customers are treated as fulfillment activities and are recorded in both net sales and cost of goods sold at the time control is transferred to the customer. Due to the short-term nature of our contracts with customers, we have elected to apply the practical expedients under Topic 606 to: (1) expense as incurred, incremental costs of obtaining a contract; and (2) not adjust the consideration for the effects of a significant financing component for contracts with an original expected duration of one year or less. When we satisfy (or partially satisfy) a performance obligation, prior to being able to invoice the customer, we recognize an unbilled receivable when the right to consideration is unconditional and a contract asset when the right to consideration is conditional. Unbilled receivables and contract assets are included in receivables and prepaid and other current assets, respectively, on the consolidated balance sheets. Additionally, we do not maintain contract liability balances, as performance obligations are satisfied prior to customer payment for product. Payments from customers are generally due within 30 to 60 days of invoicing, which generally occurs upon shipment or delivery of the goods.

Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that we collect from a customer, are excluded from revenue.

Certain contracts with customers include warranties associated with the delivered goods or services. These warranties are not considered to be separate performance obligations, and accordingly, we record an estimated liability for potential warranty costs as the goods or services are transferred.

With the exception of the toll processing revenue stream and certain contracts within the oil & gas equipment revenue stream, we recognize revenue at the point in time the performance obligation is satisfied and control of the product is transferred to the customer upon shipment or delivery. Generally, we receive and acknowledge purchase orders from our customers, which define the quantity, pricing, payment and other applicable terms and conditions. In some cases, we receive a blanket purchase order from our customers, which includes pricing, payment and other terms and conditions, with quantities defined at the time each customer subsequently issues periodic releases against the blanket purchase order.

For the toll processing revenue stream and certain contracts within the oil & gas equipment revenue stream, we recognize revenue over time. Revenue is primarily measured using the cost-to-cost method, which we believe best depicts the transfer of control to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation. Revenues are recorded proportionally as costs are incurred. We have elected to not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less.

Certain contracts contain variable consideration, which is not constrained, and primarily include estimated sales returns, customer rebates, and sales discounts which are recorded on an expected value basis. These estimates are based on historical returns, analysis of credit memo data and other known factors. We account for rebates by recording reductions to revenue for rebates in the same period the related revenue is recorded. The amount of these reductions is based upon the terms agreed to with the customer. We do not exercise significant judgments in determining the timing of satisfaction of performance obligations or the transaction price.
