At December 31, 2019 there were 0.5 million potentially dilutive restricted share awards with performance-based vesting targets that were not met and as such, have been excluded from the computation of diluted earnings per share. For 2021, 2020 and 2019 dividends and equivalents for share-based awards expected to be forfeited did not have a material impact on net income for basic and diluted earnings per share.
