Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation And Other Compensation Arrangements	Share-Based Compensation and Other Compensation Arrangements Restricted Stock Units On February 23, 2015, we granted to our executives 590,778 restricted stock units (RSUs) as part of our long-term incentive program with a grant date fair value of $154.64 per unit. The RSUs granted under this program will vest and settle in common stock (on a one-for-one basis) on the third anniversary of the grant date. Performance-Based Restricted Stock Units On February 23, 2015, we granted to our executives 556,203 performance-based restricted stock units (PBRSUs) as part of our long-term incentive program with a grant date fair value of $164.26 per unit. Compensation expense for the award is recognized over the three-year performance period based upon the grant date fair value estimated using a Monte-Carlo simulation model. The model used the following assumptions: expected volatility of 20.35% based upon historical stock volatility, a risk-free interest rate of 1.03%, and no expected dividend yield because the units earn dividend equivalents. Performance Awards On February 23, 2015, we granted to our executives performance awards as part of our long-term incentive program with a payout based on the achievement of financial goals for the three-year period ending December 31, 2017. At March 31, 2015, the minimum payout amount is $0 and the maximum amount we could be required to pay out is $363.
