Advanced payments from customers typically relate to contracts with respect to which the Company has significantly fulfilled its obligations, but due to the Company’s continuing involvement with the project, revenue is precluded from being recognized until title, ownership, and risk of loss have passed to the customer.</font></div></div>
CY2017	us-gaap	Revenue Recognition Percentage Of Completion Method RevenueRecognitionPercentageOfCompletionMethod	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-top:4px;text-indent:36px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Revenues for products and services under long-term contracts are recognized using the percentage-of-completion method. Sales and gross profit are recognized as work is performed based upon the proportion of actual costs incurred to estimated total project costs. Sales and gross profit are adjusted prospectively for revisions in estimated total project costs and contract values. For certain products and services, the percentage of completion is based upon actual labor costs as a percentage of estimated total labor costs. At the time a loss contract becomes known, the entire amount of the estimated loss is recognized in the Consolidated Statements of Operations. Costs in excess of billings are classified as work-in-process inventory. Projects with billings in excess of costs are recorded within deferred revenue.</font></div></div>

For product and service sales, the Company recognizes revenue when the following criteria have been satisfied: persuasive evidence of a sales arrangement exists; product delivery and transfer of title to the customer has occurred or services have been rendered; the price is fixed or determinable; and collectability is reasonably assured. Generally, product title passes to the customer upon shipment. In limited cases, title does not transfer and revenue is not recognized until the customer has received the products at its physical location. Revenue is recorded net of returns, allowances, customer discounts, and incentives. Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net (excluded from revenues) basis. Shipping and handling costs are included in cost of goods sold.</font></div></div>

Actual results could differ from those estimates.</font></div></div>
