6.   At December 31, 2010, approximately 37 percent of the Company’s inventories had been valued under the last-in, first-out (“LIFO”) method. At June 30, 2011, approximately 42 percent of the Company’s inventories are valued under the LIFO method. The remaining inventories have been valued under the first-in, first-out (“ FIFO”) method or average cost method. All inventories are stated at the lower of cost or market.
 
    Under the LIFO method, inventories have been reduced by approximately $191,180 and $261,886 at December 31, 2010 and June 30, 2011, respectively, from current cost which would be reported under the FIFO method.
