Inventories are stated at the lower of cost or market. Cost is determined using the last-in, first-out (“LIFO”) method for 37% and 44% of the Company’s inventories at March 31, 2013 and September 30, 2012, respectively. The first-in, first-out (“FIFO”) method is used for the remainder of the inventories. If the FIFO method had been used for the inventories for which cost is determined using the LIFO method, inventories would have been $9,130 and $9,537 higher than reported at March 31, 2013 and September 30, 2012, respectively.
