At April 30, 2012 and 2011, the Company’s international subsidiaries’ inventories were $1,253,000 and $824,000, respectively, measured using the first-in, first-out (“FIFO”) method. If all of the Company’s inventories had been determined using the FIFO method at April 30, 2012 and 2011, reported inventories would have been $1.6 million and $1.5 million greater, respectively. During fiscal year 2012, the LIFO index was higher than 100% due to higher prices for certain raw materials. This increase resulted in the addition of LIFO inventory quantities carried at lower costs prevailing in prior years as compared to the cost of purchases in fiscal year 2012, the effect of which increased the cost of sales by $146,000. During fiscal year 2011, the LIFO index was less than 100% due to lower prices paid for certain raw materials. This reduction resulted in a liquidation of LIFO inventory quantities carried at higher costs prevailing in prior years as compared with the cost of purchases in fiscal year 2011, the effect of which decreased the cost of sales by $216,000.
