We generate revenue from sales of our products which incorporate our EOS software and accessories such as cables and optics to direct customers and channel partners together with post contract customer support (“PCS”). We typically sell products and PCS in a single transaction. We recognize revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery or performance has occurred; the sales price is fixed or determinable; and collectability is reasonably assured.
We define each of the four criteria above as follows:
Persuasive evidence of an arrangement exists. Evidence of an arrangement consists of stand-alone purchase orders or purchase orders issued pursuant to the terms and conditions of a master sales agreement. It is our practice to identify an end customer prior to shipment to a reseller or distributor.
Delivery or performance has occurred. We use shipping documents or written evidence of customer acceptance, when applicable, to verify delivery or performance. We recognize product revenue upon transfer of title and risk of loss, which primarily is upon shipment to customers. We generally do not have significant obligations for future performance, rights of return or pricing credits associated with our product sales. In instances where substantive acceptance provisions are specified in the customer arrangement, revenue and the related cost of revenue is deferred until all acceptance criteria have been met.
The sales price is fixed or determinable. We assess whether the sales price is fixed or determinable based on payment terms and whether the sales price is subject to refund or adjustment.
Collectability is reasonably assured. We assess probability of collectability on a customer-by-customer basis. Our customers and channel partners are subjected to a credit review process that evaluates their financial condition and ability to pay for products and services.
PCS, which includes technical support, hardware repair and replacement parts beyond standard warranty, bug fixes, patches and unspecified upgrades on a when-and-if-available basis, is offered under renewable, fee-based contracts. We initially defer PCS revenue and recognize it ratably over the life of the PCS contract, with the related expenses recognized as incurred. PCS contracts usually have a term of one to three years. We include billed but unearned PCS revenue in deferred revenue.
We report revenue net of sales taxes. We include shipping charges billed to customers in revenue and the related shipping costs are included in cost of goods sold.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
