Cost is determined by the last-in, first-out (LIFO) method by the parent company and by the first-in, first-out (FIFO) method by its subsidiaries. Note 2: Inventories Inventories consist of the following. 2012 $1,264,646 240,988 2011 Raw materials Work in process Finished goods and display units Total inventories Less: Amount classified as long-term $2,321,178 171,222 711,252 129,406 1,635,040 3,203,652 1,468,779 294,546 Current portion $1,340,494 $1,734,873 Inventories are stated at the lower of cost determined by the LIFO method or market for Prab Robots, Inc. In- ventories for the two wholly-owned subsidiaries, Prab Command, Inc. (U.S.) and Prab Limited (U.K.) are stated on the FIFO method which amounted to $566,000 at October 31, 2011. No inventory is stated on the FIFO method at October 31, 2012. Included in inventory stated at FIFO cost was $32,815 at October 31, 2011, of Prab Command inventory classified as an asset from discontinued operations (see Note 14). If the FIFO method had been used for the entire consolidated group, inventories after an adjustment to the lower-of-cost-or-market, would have been approximately $2,000,000 and $3,800,000 at October 31, 2012 and 2011, respectively. Inventory has been written down to estimated net realizable value, and results of operations for 2012, 2011, and 2010 include a corresponding charge of approximately $863,000, $960,000, and $273,000, respectively, which represents the excess of LIFO cost over market. Inventory of $294,546 and $1,468,779 at October 31, 2012 and 2011, respectively, shown on the balance sheet as a noncurrent asset represents that portion of the inventory that is not expected to be sold currently. Reduction in inventory quantities during the years ended October 31, 2012, 2011, and 2010 resulted in liquida- tion of LIFO inventory quantities carried at a lower cost prevailing in prior years as compared with the cost of fiscal 2009 purchases. The effect of these reductions was to decrease the net loss by approximately $24,000, $157,000 and $90,000 at October 31, 2012, 2011, and 2010, respectively.
