NOTE B - INVENTORIES

Inventories are stated at the lower of cost or market. The costs for approximately 73% of inventories at March 31, 2013 and December 31, 2012 are determined using the last-in, first-out (LIFO) method, with the remainder generally determined using the first-in, first-out (FIFO) method applied on a consistent basis. An actual valuation of inventory under the LIFO method is made at the end of each year based on the inventory levels and costs at that time. Interim LIFO calculations are based on management’s estimate of expected year-end inventory levels and costs and are subject to the final year-end LIFO inventory valuation.

The major components of inventories are as follows (net of LIFO reserves of $54.1 million and $53.2 million at March 31, 2013 and December 31, 2012, respectively):

(Thousands of dollars)	March 31, 2013		December 31, 2012
Raw materials and in-process	$	25,207	$	23,967
Finished parts		52,552		52,607
Finished products		14,554		14,324
Total inventories	$	92,313	$	90,898
