In 2009 the Company executed an option and JV agreement with the predecessor company of Inventus. In 2016 Endurance sold its remaining 35.5% participating interest in the Pardo JV for 25,500,000 shares of Inventus and $75,000 in cash resulting in Endurance becoming a shareholder of Inventus; effectively exchanging its ownership interest in the Pardo JV for a large shareholding in Inventus. As of December 31, 2021, Endurance's remaining share ownership has been diluted to less than 10% of the issued and outstanding shares of Inventus.
