Revenue, Performance Obligation, Description of Timing We typically receive payment within 30 days or less (depending on the terms of the invoice) once delivery is made.  
Contract with Customer, Timing of Satisfaction of Performance Obligation and Payment We have entered into contractual arrangements where we license proprietary technology to customers related to the optimization process for operating LNG plants. The agreements typically provide for negotiated payments to be made at stated milestones. The payments are not directly related to our performance under the contract and are recorded as deferred revenue to be recognized as revenue when the customer can utilize and benefit from their right to use the license. Payments are received in installments over the construction period.
