[1] Warrants held by Arch and HPS were not included in the computation of diluted earnings because the exercise price of the warrants exceeded the market price of the common shares during the period and the exercise of the warrants would have been anti-dilutive. The warrants expired on March 25, 2020. The number of common shares issuable upon exercise of the warrants that was excluded was 1,704,691 common shares.
