Share-Based Compensation

The Corporation adopted the 2012 Equity Incentive Plan (the “Plan”) during the quarter ended June 30, 2012. The Plan is administered by the Compensation Committee of the Board of Directors of the Corporation and provides for the grant of equity ownership opportunities through incentive stock options and nonqualified stock options, restricted stock, restricted stock units, dividend equivalent units, and any other type of award permitted by the Plan. As of December 31, 2017, 211,835 shares were available for future grants under the Plan. Shares covered by awards that expire, terminate or lapse will again be available for the grant of awards under the Plan. The Corporation may issue new shares and shares from its treasury stock for shares delivered under the Plan.

Restricted Stock

Under the Plan, the Corporation may grant restricted stock to plan participants, subject to forfeiture upon the occurrence of certain events until the dates specified in the participant’s award agreement. While restricted stock is subject to forfeiture, restricted stock participants may exercise full voting rights and will receive all dividends and other distributions paid with respect to the restricted shares. Restricted stock units do not have voting rights and are provided dividend equivalents. The restricted stock granted under the Plan is typically subject to a vesting period. Compensation expense is recognized over the requisite service period of generally four years for the entire award on a straight-line basis. Upon vesting of restricted stock, the benefit of tax deductions in excess of recognized compensation expense is reflected as an income tax benefit in the Consolidated Statements of Income.

Restricted stock activity for the year ended December 31, 2017, 2016 and 2015 was as follows:
