Inventories
 
Inventories valued at LIFO cost represented 45% and 37% of total inventory at September 30, 2015 and December 31, 2014, respectively.  The excess of current cost over LIFO valued inventories was approximately $10,230,000 at September 30, 2015 and December 31, 2014. An actual valuation of inventory under the LIFO method is made only at the end of each year based on the inventory levels and costs at that time.  Accordingly, interim LIFO must necessarily be based, to some extent, on management's estimates at each quarter end. Net inventories consist of the following:

Inventory obsolescence reserves were $8,050,000 at September 30, 2015 and $7,601,000 at December 31, 2014.  The increase in reserve for obsolescence resulted from the Company's quarterly review in the normal course of business.
