1     Represents a combination of unvested RSUs and PRSUs that are dilutive with the exception of December 31, 2019 at which time all of our unvested PRSUs were determined to be at a zero percent vesting level due to the relative performance of our common stock. For the year ended December 31, 2020, approximately 0.1 million potentially dilutive securities had the effect of being anti-dilutive and were excluded from the calculation of diluted earnings per common share.
