Inventory Disclosure [Text Block] | Note 3 – Inventories Inventories are stated at the lower of cost or market. Replacement cost approximates current cost and the excess over LIFO cost is approximately $ 59.7 million and $58.4 million at December 31, 2017 and 2016, respectively. Some inventory quantities were reduced during 2017, resulting in liquidation of some LIFO quantities carried at lower costs from earlier years versus current year costs. The related effect increased net income by approximately $0.5 million. Allowances for excess and obsolete inventory totaled $4.9 million and $4.5 million at December 31, 2017 and 2016, respectively.
