The Company maintains certain stock-based compensation plans, approved by the Company’s shareholders, that are administered by the Management Development and Compensation Committee (the “Compensation Committee”) of the Board. In May 2015, the Company’s shareholders approved the 2015 Long-Term Incentive Plan (the “2015 Plan”) to replace the 2009 Management Stock Incentive Plan and the 2009 Directors’ Stock Incentive Plan (collectively, the “2009 Plans”). A total of 438,076 shares transferred from the 2009 Plans were available for grant pursuant to the 2015 Plan. In addition, any shares subject to outstanding awards under the 2009 Plans that are canceled, expired, forfeited or otherwise not issued or are settled in cash will become available for future award grants under the 2015 Plan. As of December 31, 2018, there were approximately 278,000 shares available for grant under the 2015 Plan.

Under the Plan, the Compensation Committee may establish and prescribe grant guidelines including various terms and conditions for the granting of stock-based compensation. For stock options, the exercise price of each option equals the market price of the Company’s stock on the date of the grant. All options expire after a period of ten years from the date of grant and generally become fully exercisable over a period of 3 to 5 years from the grant date. When an option recipient exercises their options, the Company issues shares from treasury stock and records the proceeds as additions to capital. Shares of restricted stock granted to employees generally vest over 2 to 3 years from the grant date. Fifty percent of the shares of restricted stock granted to non-employee directors generally vests on the date of grant and the remaining fifty percent generally vests one year from the grant date. Vesting of the shares may be based on years of service, established performance measures or both. If restricted stock grants are forfeited before they vest, the shares are reacquired into treasury stock. Restricted stock units granted to employees generally fully vest on the third anniversary of the date of grant.

The share-based compensation plans were established to allow for the granting of compensation awards to attract, motivate and retain employees, executive officers and non-employee directors who contribute to the long-term growth and profitability of the Company and to give such persons a proprietary interest in the Company, thereby enhancing their personal interest in the Company’s success.

The Company awarded grants of restricted stock units to certain members of management during the year ended December 31, 2018. The awards will be earned based on the Company’s achievement of a relative total shareholder return (“TSR”) performance requirement, on a percentile basis, compared to the SNL Small Cap Bank & Thrifts Index over a three-year performance period ended December 31, 2020. If earned at target level, members of management will receive up to 14,877 shares of our common stock in the aggregate, which will vest on February 27, 2021 assuming the recipient’s continuous service to the Company.

The grant-date fair value of the TSR performance award granted during the year ended December 31, 2018 was determined using the Monte Carlo simulation model on the date of grant, assuming the following (i) expected term of 2.84 years, (ii) risk free interest rate of 2.39%, (iii) expected dividend yield of 2.83% and (iv) expected stock price volatility over the expected term of the TSR performance award of 21.2%. The grant-date fair value of all other restricted stock awards is equal to the closing market price of the Company’s common stock on the date of grant.

The Company granted additional restricted stock units to management during the year ended December 31, 2018. These awards will vest after completion of a three-year service requirement.
