Inventory Disclosure [Text Block] | 1 0. Inventories Effective December 30, 2007 (beginning of 4th quarter of Fiscal Year 2008), the Company change d its inventory valuatio n method from the lower of cost, d etermined under the FIFO method, or market to the lower of cost, determined under the LIFO method, or market. In the high inflation environment that the Company was experiencing, the Company believed that the LIFO inventory method was preferable over the FIFO method because it better compares the cost of current production to cur rent revenue. The effect of LIFO was to increase net earnings by $16.1 million in 2016, reduce net earnings by $6.9 million in 2015, and reduce net earnings by $13.2 million in 2014, compared to what would have been reported using the FIFO inventory method. The increase in earnings per share was $1.62 ($1.60 diluted) in 2016, reduce earnings per share was $0.64 ($0.63 diluted) in 2015, and reduce earnings per share was $1.19 ($1.19 diluted) in 2014. During 2014, certain inventory quantities accounted for o n the LIFO method were reduced, resulting in the liquidation of certain quantities carried at costs prevailing in prior years. The impact on net earnings of these liquidations was no impact in 2016 and 2015, and an increase of $4.8 million during 2014. The inventories by categor y and the impact of using the LIFO method are shown in the following table:
