During 2017, the Company recorded $2.7 million of LIFO expense as a result of increased metals pricing during 2017. The LIFO expense decreased the Company’s inventory balance and increased its cost of materials sold. During 2016, the Company recorded $1.5 million of LIFO income as a result of decreased metals pricing during 2016. The LIFO income increased the Company’s inventory balance and decreased its cost of materials sold. If the FIFO method had been in use, inventories would have been $5.3 million and $8.0 million lower than reported at December 31, 2017 and 2016, respectively.
