13.  Other Liabilities

As a part of the September 2018 public offering, we sold 13,062,878 warrants priced at $0.01 per warrant. Two warrants are redeemable for one Common Share of the Company’s stock at a price of $1.00 per full share. Because the warrants are priced in US$ and the functional currency of the Ur-Energy Inc. is C$, this created a derivative financial liability. The liability created and adjusted quarterly is a calculated fair value using the Black-Scholes technique described below as there is no active market for the warrants. Any income or loss is reflected in net income for the period. The initial valuation at the time of the offering was $2.212.  The revaluation as of December 31, 2018 resulted in a gain of $581 for the period ended December 31, 2018 which is reflected on the statement of operations.  The Black-Sholes calculations were based on the current market price, the remaining life to expiration, volatility ranging from 55.2% to 56.6% and a risk-free interest rate which ranged from 1.9% to 2.2%.  In addition, as the liability exists in the Canadian parent company, both the liability and the gain or loss are subject to fluctuations in the exchange rate.
