Policies
Inventory, Policy	Inventory Inventories are valued at the lower of weighted average cost or market value. Our industry experiences changes in technology, changes in market value and availability of raw materials, as well as changing customer demand. We make provisions for estimated excess and obsolete inventories based on regular audits and cycle counts of our on-hand inventory levels and forecasted customer demands and at times additional provisions are made. Any inventory write offs are charged to the reserve account. As of March 31, 2019 and December 31, 2018, we had a reserve for potentially obsolete inventory of $250,000.

Disclosure of inventory accounting policy for inventory classes, including, but not limited to, basis for determining inventory amounts, methods by which amounts are added and removed from inventory classes, loss recognition on impairment of inventories, and situations in which inventories are stated above cost.
