6. Trade Inventory

The Company’s trade inventory consisted of the following (in thousands):

Renin reviews its slow-moving and obsolete inventory for potential write-downs on a quarterly basis. During the fourth quarter of 2021, Renin commenced a strategic initiative to exit and consolidate certain warehouse facilities, and as a result of this initiative, Renin determined that it would discount various slow-moving inventories to accelerate the sale of such inventories. As a result of this determination, Renin recognized a $2.4 million write-down on certain slow-moving inventories, which is included in cost of trade sales for the year ended December 31, 2021, in order to reflect such inventories at their estimated realizable value based upon the expected discounts necessary to sell the inventories within the desired timeframes.
