Orion periodically reviews inventories for both obsolescence and loss in value. In this review, Orion makes assumptions about the future demand for and the future market value of the inventory and, based on these assumptions, estimates the amount of obsolete, unmarketable or slow moving inventory. The inventory reserve for obsolete, unmarketable and slow moving assets as of December 31, 2019 and 2018 amounted to $6.7 million and $1.6 million, respectively.

In the periods ended December 31, 2019, 2018 and 2017 $6.0 million, $1.9 million and $2.7 million, respectively, were recognized as an expense for damaged and lost inventories.

As of December 31, 2019 and 2018, reserves to adjust inventories net realizable value in the amount of $1.4 million and $2.4 million, respectively, were recognized on raw materials, consumables and supplies and on finished goods.
