Improvements to Employee Share-Based Payment Accounting	Improvements to Employee Share-Based Payment Accounting In March 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-09 that requires entities to recognize the income tax effects of awards in the income statement when the awards vest or are settled. The new standard also allows entities to withhold an amount up to an employee’s maximum individual tax rate in the relevant jurisdiction without resulting in liability classification of the award. The new standard is effective for annual and interim periods beginning January 1, 2017. We have early adopted this standard as of June 30, 2016. As a result, during the second quarter we reclassified the year-to-date 2016 excess tax benefit of $14.2 million and the second quarter benefit of $9 million from paid-in capital (statements of equity) into the income taxes line on the statements of comprehensive income. The adoption did not impact the existing classification of the awards. We have also reclassified the year-to date 2016 excess tax benefits from the exercise of stock based compensation of $14.2 million from financing activities into operating activities in the statement of cash flows for the six months ended June 30, 2016. This amendment was adopted prospectively and therefore, we have not adjusted the prior periods presented. Additionally, we have reclassified $9 million and $13.6 million of employee withholding taxes paid from operating into financing activities in the statement of cash flows for the six months ended June 30, 2016 and June 30, 2015, respectively, as required by ASU 2016-09 (adopted retrospectively). The adoption of the standard resulted in an increase of $0.09 in basic and diluted earnings per common share for six months ended June 30, 2016 and an increase of $0.06 in basic and diluted earnings per common share for three months ended June 30, 2016. Following the adoption of the new standard, we have elected to continue estimating the number of awards expected to be forfeited and adjust our estimate on an ongoing basis.
