Inventories
Inventories are held at the lower of cost or market, determined under the first-in, first-out method. Inventory has been recorded at cost as of March 31, 2015 and December 31, 2014. Work in process is calculated based upon a buildup in the stage of completion using estimated labor inputs for each stage in production. The Company periodically reviews inventories for net realizable value based on quantities on hand and expectations of future use.
