Phantom Stock Option Plan and Long-term Incentive Plan

The Greene County Bancorp, Inc. 2011 Phantom Stock Option and Long-term Incentive Plan (the “Plan”) was adopted effective July 1, 2011, to promote the long-term financial success of the Company and its subsidiaries by providing a means to attract, retain and reward individuals who contribute to such success and to further align their interests with those of the Company’s shareholders. At June 30, 2017 and 2016, the Plan had 3,600,000 options authorized, of which, 2,972,982 and 2,394,782 options had been granted to date, respectively. The Plan is intended to provide benefits to employees and directors of the Company or any subsidiary as designated by the Compensation Committee of the Board of Directors of the Company (“Committee”). A phantom stock option represents the right to receive a cash payment on the date the award vests. The participant receives an amount equal to the positive difference between the strike price on the grant date and the book value of a share of the Company stock on the determination date, which is the last day of the plan year that is the end of the third plan year after the grant date of the award, unless otherwise specified by the Committee. The strike price will be the price established by the Committee, which will not be less than 100% of the book value of a share on a specified date, as determined under generally accepted accounting principles (GAAP) as of the last day of the quarter ending on or immediately preceding the valuation date with adjustments made, in the sole discretion of the Committee, to exclude accumulated other comprehensive income (loss). The liability for the phantom stock option plan is re-measured at each reporting period based on the difference between the strike price and the current period end book value per share of the Company’s common stock, excluding accumulated other comprehensive income (loss).

A summary of the Company’s phantom stock option activity and related information for its option plan for the years ended June 30, 2017 and 2016 is as follows:
