Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation Plans	Share-Based Compensation Plans During the three months ended June 30, 2017 and 2016, we recognized share-based compensation expense of $7.6 and $7.7, respectively, and $14.8 and $14.9 for the six months ended June 30, 2017 and 2016, respectively. The expense relates to stock options, deferred stock, restricted stock and performance share units. We recognize share-based compensation expense in selling and administrative expenses on a straight-line basis over the service period of each award. Consideration received from share-based awards was $36.1 and $3.6 for the six months ended June 30, 2017 and 2016, respectively. In March 2016, the FASB issued new accounting guidance on share-based payments. The new guidance requires all excess tax benefits and tax deficiencies from share-based compensation to be recognized as income tax expense or benefit in the income statement rather than capital in excess of par value. The requirement to record the benefit or deficiency within the provision of income taxes is effective on a prospective basis. The guidance also requires the excess tax benefit or deficiency to be classified as an operating activity rather than a financing activity on our Consolidated Statements of Cash Flows. To eliminate diversity in practice, the guidance also requires that cash payments to tax authorities in connection with shares withheld to meet employees' statutory tax withholding requirements are to be included retrospectively, for all periods presented, as financing activities on our Consolidated Statements of Cash Flows, consistent with our methodology. We adopted the new guidance effective January 1, 2017, and the impact of the adoption of this guidance resulted in a $4.4 favorable impact on net earnings, or $0.06 per share, for the first half of 2017.
