NOTE 6. INVENTORY

Inventories consisted of the following at March 31, 2022 and December 31, 2021 (in thousands):

	March 31,		December 31,
	2022		2021
Raw materials	$	1,791	$	1,343
Work in process	1,762		1,625
Finished goods	1,952		2,099
	$	5,505	$	5,067

During the fourth quarter of 2021, the Company took charges to cost of sales for inventory provisions primarily related to the write-down of excess quantities of instrument raw materials and work in process, whose inventory levels were higher than our updated forecasts of future demand for those products. Inventory provisions totaled $4.5 million during the fourth quarter of 2021. None of this inventory had been sold to customers for the three months ended March 31, 2022.
