We maintain consignment inventory, included in finished goods inventories, of our On-X heart valves at domestic and foreign hospital locations to facilitate usage. We retain title to this consignment inventory until the valve is implanted, at which time we invoice the hospital. As of September 30, 2017 we had $5.8 million in consignment inventory, with approximately 85% in domestic locations and 15% in foreign locations. As of December 31, 2016 we had $4.9 million in consignment inventory with approximately 80% in domestic locations and 20% in foreign locations.
