The number of shares used to compute basic and diluted earnings per-share for the three and nine months ended September 30, 2015 and 2014, is as follows (in millions, except per-share amounts):

	Three Months Ended September 30, 2015					Nine Months Ended September 30, 2015
			Weighted	Per				Weighted	Per
			Average	Common				Average	Common
	Net		Common	Share		Net		Common	Share
2015	Income		Shares	Amount		Income		Shares	Amount

Basic:	$	41.5	43.5	$	0.95	$	76.4	43.5	$	1.76

Diluted:	$	41.5	44.0	$	0.94	$	76.4	44.0	$	1.74

	Three Months Ended September 30, 2014					Nine Months Ended September 30, 2014
			Weighted	Per				Weighted	Per
			Average	Common				Average	Common
	Net		Common	Share		Net		Common	Share
2014	Income		Shares	Amount		Income		Shares	Amount

Basic:	$	21.5	43.0	$	0.50	$	43.0	43.0	$	1.00

Diluted:	$	21.5	43.4	$	0.50	$	43.0	43.3	$	1.00

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.
