The following table summarizes the components of inventories at the different stages of production as of February 28, 2019 and February 28, 2018 (in thousands):

	2019		2018
Raw material	$	21,717	$	15,854

The excess of current costs at FIFO over LIFO stated values was approximately $5.0 million and $4.9 million as of fiscal years ended 2019 and 2018, respectively.  During both fiscal year 2019 and 2018, as inventory quantities were reduced, this resulted in a liquidation of LIFO inventory quantities carried at lower costs prevailing in prior years as compared with the cost of fiscal year 2018 and 2017.  The effect decreased cost of sales by approximately $0.1 million, $0.3 million and $0.2 million for fiscal years 2019, 2018 and 2017, respectively.  Cost includes materials, labor and overhead related to the purchase and production of inventories.
