During 2017, Solitario exercised 7,240,000 of its Vendetta Warrants and received 7,240,000 Vendetta common shares, by paying $578,000 in cash to Vendetta. As a result, as of December 31, 2017, Solitario no longer owns any Vendetta Warrants. Upon the exercise of the Vendetta Warrants, Solitario transferred the fair value of the Vendetta Warrants on the date of exercise of $949,000 along with the cash paid to exercise the Vendetta Warrants of $578,000 to marketable equity securities as the cost of the 7,240,000 common shares of Vendetta acquired.
