Inventory

3. Inventory

Inventories are stated at the lower of cost or market. Cost is determined using the weighted average cost of raw materials, which approximates the first-in, first-out (“FIFO”) method, and includes allocations of manufacturing labor and overhead. Provisions are made to reduce potentially excess, obsolete or slow-moving inventories to their net realizable value. Inventories as of June 30, 2014 and December 31, 2013, consisted of the following (in thousands):
