6. Share-Based Compensation

The Company has various stock plans under which employees and directors may be granted non-vested stock which vests over a specific time period. The 2007 Stock Plan also allows for the granting of non-qualified stock options or incentive stock options. Upon vesting, the stock options allow the participant to purchase common stock at 100% of the closing market price on the day the options were granted. No options were granted in 2016, 2015 or 2014.

As of December 31, 2016, there were 1.1 million shares available to be granted as non-vested stock under the Company’s existing stock plans.

Stock options became exercisable over a three-year vesting period, or earlier upon retirement, and expire 10 years from the date of grant. Expense for stock options was recognized on a straight-line basis over three years from the date of grant or over the period from the date of grant until the participant was retirement-eligible, whichever was less. Treasury shares are issued for non-vested stock awards and for the exercise of stock options.

The Company’s stock plans also provide for the awarding of non-vested stock. Prior to December 2014, expense for shares of non-vested stock is recognized over the vesting period or during the period from the date of grant until the participant reaches age 65, whichever is shorter. The vesting period is five years for awards granted prior to December 2013 and three years beginning with awards granted in December 2013. During the period of restriction, the holder of non-vested stock has voting rights and is entitled to receive all dividends and other distributions paid with respect to the stock.

The December 2013 grant consisted of 50% performance stock units and 50% time-vesting stock. The number of shares issued under the performance stock units was based on certain performance metrics measured over a two-year performance period and the awards had a three-year vesting period. Two-year performance that exceeded the stated performance metrics would have resulted in an award up to 150% of the original grant. The holders of the performance stock units were not entitled to vote or receive dividends and other distributions paid with respect to the stock, until the units vested and the shares of stock were issued.

The grants issued after December 2013 consisted of 100% performance stock unit awards which are based on a three-year performance and vesting period and a pro-rata vesting upon retirement. Three-year performance that exceeds the stated performance metrics would result in an award up to 150% of the original grant. The holders of the performance stock units are not entitled to vote or receive dividends and other distributions paid with respect to the stock, until the units have vested and the shares of stock are issued.

The Company expenses awards for non-vested stock, including time-vesting stock and performance stock units, based on the fair value of the Company’s common stock at the date of the grant.
