To facilitate product usage, we maintain consignment inventory of our On-X heart valves at domestic hospital locations and both On-X heart valves and JOTEC products at international hospital locations. We retain title and control over this consignment inventory until the device is implanted, at which time we invoice the hospital and recognize revenue. As of December 31, 2020 we had $11.9 million in consignment inventory, with approximately 47% in domestic locations and 53% in foreign locations. As of December 31, 2019 we had $12.0 million in consignment inventory, with approximately 51% in domestic locations and 49% in foreign locations.
