The number of shares used to compute basic and diluted earnings per-share for the three months ended March 31, 2016 and 2015, is as follows (in millions, except per-share amounts):

	Three Months Ended March 31, 2016						Three Months Ended March 31, 2015
			Weighted	Per					Weighted	Per
			Average	Common					Average	Common
	Net		Common	Share			Net		Common	Share
	Income		Shares	Amount			Income		Shares	Amount
Basic:	$	18.1	43.4	$	0.42		$	25.0	43.4	$	0.58
Effect of Dilutive Securities:			0.4	(0.01		)			0.5	(0.01		)
Diluted:	$	18.1	43.8	$	0.41		$	25.0	43.9	$	0.57

Basic earnings per-share is determined by dividing net income by the weighted-average common shares outstanding during the period.  The calculation of diluted earnings per-share includes the dilutive effect of unexercised non-qualified stock options and non-vested restricted stock units.

The computation of weighted average dilutive shares outstanding excludes certain non-qualified stock options to purchase shares of common stock where the options’ exercise prices were greater than the average market price of the Company’s common stock for the periods presented and, therefore, the effect would be anti-dilutive.
