INVENTORIES
 
      Inventories valued at LIFO represented 55% and 56% of total inventory for the years ended December 31, 2013 and 2012, respectively. The excess of current costs over LIFO-valued inventories was $9,483,000 and $8,975,000 on December 31, 2013 and December 31, 2012, respectively. (The $508,000 increase in LIFO reserve during 2013 came from reductions in inventory levels within U.S. operations. The impact of the application of the LIFO method on the Statement of Income for the years ended December 31, 2013, was a decrease to cost of sales of $508,000, and an decrease in 2012 of $484,000 and an increase in 2011 of $1,805,000.)
