During the quarter ended September 30, 2018, the Company took efforts to increase inventory levels as it prepares to deliver on current backlog and anticipated orders. Additionally, during the quarter ended September 30, 2017 the Company recorded inventory adjustments totaling $12.9 million resulting from its lower of cost or market analysis. The charge was effected because of ongoing efforts to focus and prioritize the Company’s portfolio based on year-to-date demand, market trends and a better understanding of where the Company’s offerings meet and will continue to meet customers’ needs and demand. The inventory adjustments related primarily to legacy plastics printers, refurbished and used metals printers and parts which have shown little to no use over extended periods.
