Revenue from Contracts with Customers [Abstract] |
Revenue from Contract with Customer [Text Block] | Revenue from Contracts with Customers We recognize revenue when control of promised products or services is transferred to our customers, in amounts that reflect the consideration to which we expect to be entitled in exchange for those products or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, the payment terms are identified, the contract has commercial substance and collectability of consideration is probable. We determine the appropriate revenue recognition for our contracts with customers by analyzing the type, terms and conditions of each contract or arrangement with a customer. Disaggregation of Revenue Refer to Note 8. for disaggregation of our revenues from contracts with customers by reportable segment and by geographical region, which we believe best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. Geographical region represents the location of the customer. Contract Asset and Liability Balances Differences in the timing of revenue recognition, billing and cash collection result in customer receivables, advance payments and billings in excess of revenue recognized. Customer receivables include amounts billed and currently due from customers as well as unbilled amounts (i.e., contract assets). Amounts are billed in accordance with contractual terms and unbilled amounts arise when the timing of billing differs from the timing of revenue recognized. Advance payments and billings in excess of revenue are recognized and recorded as deferred revenue, the majority of which is classified as current based on the timing of when we expect to recognize revenue. We include current deferred revenue within Other current liabilities in the accompanying condensed consolidated balance sheets. Deferred revenue represents contract liabilities and is recorded when customers remit cash payments in advance of our satisfaction of performance obligations pursuant to contractual arrangements. Contract liabilities are reversed when the performance obligation is satisfied and revenue is recognized. The table below represents the balances of our customer receivables and deferred revenue:

Performance Obligations A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. Our performance obligations are satisfied at a point in time for sales of equipment or product and over time for our software hosting and leak detection monitoring services. Performance obligations are supported by customer contracts, which provide frameworks for the nature of the distinct products or services. The transaction price is adjusted for our estimate of variable consideration which may include discounts and rebates. To estimate variable consideration, we apply the expected value or the most likely amount method, based on whichever method most appropriately predicts the amount of consideration we expect to receive. The method applied is typically based on historical experience and known trends. We constrain the amounts of variable consideration that are included in the transaction price, to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur or when uncertainties around the variable consideration are resolved. We exclude from the measurement of the transaction price all taxes assessed by a governmental authority. We do not adjust the transaction price of a contract for the effects of a significant financing component if, at the inception of the contract, we expect that the period between when we transfer a product or service to a customer and when a customer remits payment will be one year or less. Revenue for the sale of our products is recognized when the obligations of the terms of our contract are satisfied, which is when the customer is able to direct the use of and obtain substantially all of the benefits from the product, which generally occurs upon shipment when control of the product transfers to the customer. We offer warranties to our customers which provide assurance that the products provided will function as intended and comply with any agreed-upon specifications. These warranties cannot be purchased separately from our products. Costs to Obtain or Fulfill a Contract Shipping and handling costs associated with freight activities after the customer has obtained control of a product are included in cost of sales at the time the related revenue is recognized. We incur certain incremental costs to obtain a contract, which primarily relate to incremental sales commissions. Our sales commissions are paid based on a combination of orders and shipments, and we reserve the right to claw back any commissions in case of product returns, cancellations or lost collections. As the expected benefit associated with these incremental costs is generally one year or less based on the nature of the product sold and benefits received, we do not capitalize the related costs and expense them as incurred.
