See Note 8, "Common Share-Based Compensation", for a summary of common share awards outstanding under the company’s common share-based compensation programs. These programs could result in the issuance of common shares from time to time that would affect the measurement of basic and diluted earnings per common share.

There were no common shares of performance-vested awards excluded from the computation of diluted earnings per common share during the three months ended March 31, 2021 due to their inclusion being anti-dilutive (three months ended March 31, 2020: 0.3 million). There were no common shares of time-vested awards excluded from the computation of diluted earnings per common share during three months ended March 31, 2021 (three months ended March 31, 2020: none).
