Revenue from Contract with Customer [Abstract] |
Revenue from Contract with Customer | 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 customer contract or arrangement. Disaggregation of Revenue Refer to Note 14. 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 certainty 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 including 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 and classified as current or noncurrent based on the timing of when we expect to recognize the related revenue. We include current deferred revenue and noncurrent deferred revenue within Other current liabilities and Other noncurrent liabilities, respectively, in the accompanying consolidated balance sheets. Refer to Note 11. for current and noncurrent amounts. Deferred revenue represents contract liabilities and is recorded when customers remit cash payments in advance of our satisfaction of performance obligations under contractual arrangements. Contract liabilities are reversed when the performance obligation is satisfied and revenue is recognized. Deferred revenue primarily consists of amounts related to monitoring, leak detection, software and hosting services. During fiscal year 2024, we recognized approximately $8.6 million of revenue that was previously deferred and we recorded approximately $12.2 million of additional deferred revenue. We estimate that currently deferred revenue will be recognized as follows: $7.1 million in 2025, $1.4 million in 2026, $1.2 million in 2027, $1.1 million in 2028, $0.6 million in 2029 and $1.4 million thereafter. 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 a customer. Our performance obligations generally are satisfied at a point in time as related to sales of equipment and products and over time as related to 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 more 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 regarding 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. Revenues from products and services transferred to customers at a point in time represented 98% of our revenues in fiscal years 2024, 2023, and 2022. The revenues recognized at a point in time related to the sale of our products and services are recognized when the obligations of the contract terms are satisfied, which is when the customer is able to direct the use of and obtain substantially all of the benefits from the product or service, which generally occurs upon shipment when control of the product or service transfers to the customer. Revenues from products and services transferred to customers over time represented 2% of our revenues in fiscal years 2024, 2023, and 2022. We offer assurance warranties to our customers that the products provided will function as intended and comply with any agreed-upon specifications. These cannot be purchased separately. On limited products, we offer extended warranties which may be purchased separately. Costs to Obtain or Fulfill a Contract Shipping and handling costs associated with freight activities after the customer has obtained control are accounted for as fulfillment costs and are expensed to Cost of sales within our consolidated statements of operations at the time revenue is recognized. We incur certain incremental costs to obtain a contract, which primarily relate to incremental sales commissions. 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 the practical expedient to expense them as incurred and therefore do not capitalize the related costs. Our commissions are paid based on orders or shipments, and we reserve the right to claw back any commissions in the event of product returns or lost collections.
