Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Share-Based Compensation | 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 September 30, 2017, 217,475 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, with the exception of restricted stock units, which do not have voting rights and are provided dividend equivalents, restricted stock participants may exercise full voting rights and will receive all dividends and other distributions paid with respect to the restricted shares. 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 unaudited Consolidated Statements of Income. Restricted stock activity for the year ended December 31, 2016 and the nine months ended September 30, 2017 was as follows:
|  | Number of Restricted Shares/Units |  | Weighted Average Grant-Date Fair Value
Nonvested balance as of December 31, 2015 |  | 135,471 |  |  | $ | 20.13 |
Granted |  | 60,415 |  |  | 22.74 |
Vested |  | (56,090 | ) |  | 18.71 |

Nonvested balance as of September 30, 2017 |  | 127,656 |  |  | $ | 21.39 |
As of September 30, 2017, the Corporation had $2.6 million of deferred unvested compensation expense, which the Corporation expects to recognize over a weighted-average period of approximately 3.03 years. For the three and nine months ended September 30, 2017 and 2016, share-based compensation expense related to restricted stock included in the unaudited Consolidated Statements of Income was as follows:
