Deferred Revenue

Deferred revenue of $8,034 and $5,715 as of December 31, 2014 and 2013, 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 that the Company has significantly fulfilled its obligations and the customers have paid, but due to the Company’s continuing involvement with the material, revenue is precluded from being recognized until title, ownership, and risk of loss have passed to the customer.
