– Inventories
 
LIFO inventories are stated at the lower of cost or market and all other inventories are stated at the lower of cost or net realizable value. Replacement cost approximates current cost and the excess over LIFO cost is approximately
$62.5
million and
$63.7
million at
December 
31,
2019
and
2018,
respectively. Some inventory quantities were reduced during
2019
and
2018,
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
$2.0
million during
2019
and
$0.2
million during
2018.
Allowances for excess and obsolete inventory totaled
$5.9
million and
$5.3
million at
December 
31,
2019
and
2018,
respectively.
