Weighted-average shares outstanding	423.2	485.8	423.1	485.6
Share-based payment awards classified as participating securities (1)	0.1	0.4	0.2	0.5
Basic weighted-average shares outstanding	423.3	486.2	423.3	486.1
Dilutive securities (2)	0.2	—	0.3	—

(1) For the three months ended June 30, 2019 and 2018, 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.

The three and six months ended June 30, 2018 excludes 0.8 million and 0.9 million potentially dilutive share-based awards as their effect would be anti-dilutive.
