Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	During the quarter ended June 30, 2016, we granted 3.4 million non-vested share units to our employees pursuant to our 2012 Long-Term Incentive Plan, which will be settled in cash upon vesting. Grants of our non-vested share units generally vest at rates of 20% or 33% per year, as determined by a committee or subcommittee of the Board of Directors at the time of grant. The non-vested share units have dividend rights effective on the date of grant. Compensation expense for awards to be settled in cash is remeasured each quarter with a cumulative adjustment to compensation cost during the period based on changes in our share price. The weighted-average grant date fair value for our non-vested share units to be settled in cash that were granted during the quarter ended June 30, 2016 was $9.65.

The entire disclosure for compensation-related costs for equity-based compensation, which may include disclosure of policies, compensation plan details, allocation of equity compensation, incentive distributions, equity-based arrangements to obtain goods and services, deferred compensation arrangements, employee stock ownership plan details and employee stock purchase plan details.
