Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Share-Based Compensation | Shareholders' Equity Consistent with prior years' practice, during the three-month period ended June 30, 2015, we granted 1.7 million non-vested share awards to our employees, officers and non-employee directors for annual equity awards and for equity awards granted to new or recently promoted employees, pursuant to our 2012 Long-Term Incentive Plan. Grants of non-vested share awards 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 the grant. Our non-vested share awards have dividend rights effective on the date of grant and are measured at fair value using the market value of our shares on the date of grant. The weighted-average grant-date fair value of non-vested share awards granted during the three-month period ended June 30, 2015 was $23.41 per share.
