(1)For the three months ended September 30, 2020 and 2019, dividends and equivalents for share-based awards that are expected to be forfeited do not have a material effect on net income for basic and diluted earnings per share.

(2)The nine months ended September 30, 2020 excludes 0.9 million of potentially dilutive share-based awards as their effect would be anti-dilutive.

(3)The three and nine months ended September 30, 2019 excludes 0.4 million of potentially dilutive share-based awards as their effect would be anti-dilutive.
