We establish reserves for estimated excess, obsolete, or unmarketable inventory equal to the difference between the cost of the inventory and the estimated fair value of the inventory based upon assumptions about future demand and market conditions. At September 30, 2018 and December 31, 2017, raw materials reserves totaled $17.2 million and $15.0 million, respectively, and finished goods inventory reserves totaled $10.6 million and $8.3 million, respectively.
