Deferred Revenue

Deferred revenue of $6,934 and $8,034 at December 31, 2015 and 2014, respectively, consists of customer payments received for which the revenue recognition criteria have not yet been met as well as billings in excess of costs on percentage of completion projects.  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.
