        <footnote id="F3">The performance period for Performance Stock under the long-term incentive compensation plan initiated in June 2014 terminated in calendar 2017.

As a result, in accordance with the long-term incentive compensation plan, the Company issued shares of unrestricted stock at approximately 35% of the Target.</footnote>
