Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-based incentive awards are provided to employees under the terms of various share-based compensation plans (collectively, the “Plans”). The Plans are administered by the Compensation Committee of the Board of Directors and principally include at-the-money stock options, unvested stock and cash awards. Unvested stock awards include grants of market-based, performance-based and time-vested restricted stock rights. Under the terms of our Plans, dividends are not paid unless the stock award vests. Upon vesting, the amount of the dividends paid is equal to the aggregate dividends declared on common shares during the period from the grant date of the award until the date the shares underlying the award are delivered.

The following table provides information on share-based compensation expense and income tax benefits recognized during the periods:
