EMPLOYEE STOCK BENEFIT PLANS

On May 1, 2012, the shareholders approved the 2012 Stock Award and Incentive Plan (the 2012 Plan), which replaced the 2007 Stock Incentive Plan. The 2012 Plan provides for 109 million shares to be authorized for grants, plus any shares from outstanding awards under the 2007 Plan as of February 29, 2012 that expire, are forfeited, canceled, or withheld to satisfy tax withholding obligations. As of December 31, 2015, 108 million shares were available for award. Shares are issued from treasury stock to satisfy our obligations under this Plan.

Executive officers and key employees may be granted options to purchase common stock at no less than the market price on the date the option is granted. Options generally become exercisable ratably over four years and have a maximum term of ten years. The plan provides for the granting of stock appreciation rights whereby the grantee may surrender exercisable rights and receive common stock and/or cash measured by the excess of the market price of the common stock over the option exercise price. The Company has not granted any stock options or stock appreciation rights since 2009.

Restricted stock units may be granted to key employees, subject to restrictions as to continuous employment. Generally, vesting occurs ratably over a four year period from grant date. Compensation expense is recognized over the vesting period. A stock unit is a right to receive stock at the end of the specified vesting period but has no voting rights.

Market share units are granted to executives. Vesting is conditioned upon continuous employment until the vesting date and payout factor is at least 60% of the share price on the award date. The payout factor is the share price on vesting date divided by share price on award date, with a maximum of 200%. The share price used in the payout factor is calculated using an average of the closing prices on the grant or vest date, and the nine trading days immediately preceding the grant or vest date. Vesting occurs ratably over four years.

Performance share units are granted to executives and have a three year cycle and are granted as a target number of units subject to adjustment based on company performance. The number of shares issued when performance share units vest is determined based on the achievement of annual performance goals. The number of shares issued for 2014-2016 and 2015-2017 performance share unit awards are also adjusted based on the Company's three-year total shareholder return relative to a peer group of companies. Vesting occurs on the third anniversary of the grant date.

Stock-based compensation expense for awards ultimately expected to vest is recognized over the vesting period. Forfeitures are estimated based on historical experience at the time of grant and revised in subsequent periods if actual forfeitures differ from those estimates. Other information related to stock-based compensation benefits are as follows:
