(1)	Participating securities include nonvested shares, certain time-based RSUs and vested market measure-based RSUs.

Share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are considered participating securities. The impact of potentially dilutive common shares, including stock options, RSUs, shares issuable under forward equity sale agreements and other securities are considered in our diluted earnings per share calculation for the three months ended March 31, 2019 and 2018. Certain market measure-based RSUs are not included in dilutive securities for the three months ended March 31, 2019 and 2018, as not all performance metrics had been met by the end of the applicable reporting periods.
