Long-term inventory represents inventory held in excess of our current (next 12 months) requirements based on our recent sales and forecasted level of sales. We have developed programs to reduce the inventory to normal operating levels in the near future. We expect to sell the above inventory, net of reserves, at or above the stated cost and believe that no loss will be incurred on its sale.

Current finished goods include distributor channel inventories in the amounts of approximately $1,698 and $1,520 as of December 31, 2014 and 2013, respectively. Distributor channel inventories represent inventory at distributors and other customers where revenue recognition criteria have not been achieved.

The losses incurred on valuation of inventory at the lower of cost or market value and write-off of obsolete inventory amounted to $946 and $996 during the years ended December 31, 2014 and 2013, respectively.
