The dilutive effect of share-based compensation awards has been calculated using the treasury-stock method. For the three months ended June 30, 2018 and 2017, an aggregate of less than 0.1 million RSUs and PBRSUs, and an aggregate of less than 0.1 million RSUs, respectively, were excluded from the weighted-average diluted common shares outstanding due to their anti-dilutive effect. For the six months ended June 30, 2018 and 2017, an aggregate of less than 0.1 million RSUs and PBRSUs and an aggregate of less than 0.1 million of RSUs, respectively, were excluded from the weighted-average diluted common shares outstanding due to their anti-dilutive effect.
