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 We disaggregate our revenues from contracts with customers by reportable segment (see Note 10.) and further by geographical region as we believe this 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 we expect to receive within one year and therefore is included within Other current liabilities in the accompanying consolidated balance sheets. Deferred revenues represent contract liabilities and are recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are relieved and revenue is recognized when the performance obligation is satisfied. The table below represents the balances of our customer receivables and deferred revenues.

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 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. We allocate the transaction price of each contract to the performance obligations on the basis of standalone selling price and recognize revenue when control of the performance obligation transfers to the customer. 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 based typically on historical experience and known trends. We do not recognize variable consideration in the event there are uncertainties in the amount of variable consideration to be paid nor when it is probable there will be a significant reversal in the related revenue. We exclude from the measurement of the transaction price all taxes assessed by a governmental authority. We classify shipping and handling costs, such as freight to our customers’ destinations, as a component of Cost of sales. We have elected to use the practical expedient to 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. The revenues recognized at a point in time related to the sale of our products are recognized when the obligations of the terms of our contract are satisfied, which generally occurs upon shipment when control of the product transfers to the customer. We offer warranties to our customers in the form of assurance-type warranties that provide assurance that the products provided will function as intended and comply with any agreed-upon specifications. These cannot be purchased separately. Costs to Obtain or Fulfill a Contract We incur certain incremental costs to obtain a contract, which primarily relate to incremental sales commissions. Our 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 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 have applied a practical expedient and therefore do not capitalize the related costs and expense them as incurred.
