The Company’s inventories are primarily stated at standard cost, which approximates actual cost determined on a first-in, first-out basis. The Company adjusts the value of its inventory to the extent management determines that the cost cannot be recovered due to obsolescence or other factors. In order to make these determinations, management uses estimates of future demand and sales prices for each product to determine the appropriate inventory reserves and to make corresponding adjustments to the carrying value of these inventories to reflect the lower of cost or market value. In the event of a sudden significant decrease in demand for the Company’s products, or a higher incidence of inventory obsolescence, the Company could be required to increase its inventory reserves, which would increase cost of sales and decrease gross profit. Field inventory represents immediately saleable finished products that are in the possession of the Company’s direct sales representatives. Consignment inventory represents immediately saleable finished products located at third party customers, such as distributors and hospitals. Work-in-process, finished products, field inventory and consignment inventory include material, labor and production overhead costs. Deferred cost of sales result from transactions where the Company has shipped product or performed services for which all revenue recognition criteria have not yet been met. Once all revenue recognition criteria have been met, revenue previously recorded as deferred and associated cost of sales are recognized.
