Earnings Per Share

The numerator for basic and diluted earnings per share ("EPS") is net earnings attributable to Mosaic. The denominator for basic EPS is the weighted average number of shares outstanding during the period. The denominator for diluted EPS also includes the weighted average number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued, unless the shares are anti-dilutive.

The following is a reconciliation of the numerator and denominator for the basic and diluted EPS computations:



	Three months ended				Nine months ended
	September 30,				September 30,
	2017		2016		2017		2016
Net earnings attributable to Mosaic	$	227.5	$	39.2	$	323.9	$	285.9
Basic weighted average number of shares outstanding	351.1		350.1		350.9		350.4
Dilutive impact of share-based awards	1.1		1.4		1.0		1.3
Diluted weighted average number of shares outstanding	352.2		351.5		351.9		351.7
Basic net earnings per share attributable to Mosaic	$	0.65	$	0.11	$	0.92	$	0.82
Diluted net earnings per share attributable to Mosaic	$	0.65	$	0.11	$	0.92	$	0.81

A total of 3.4 million and 3.5 million shares of Common Stock subject to issuance upon exercise of stock options for the three and nine months ended September 30, 2017 and 2.6 million and 3.0 million shares and for the three and nine months ended September 30, 2016, respectively, have been excluded from the calculation of diluted EPS as the effect would have been anti-dilutive.
