        <footnote id="F3">The performance period for Performance Stock under the long-term incentive compensation plan initiated in June 2013 terminated in calendar 2016.

The Company's ROACE for the performance period was 8.4%, which exceeded the Threshold level for that performance measure.  As a result, in accordance with the long-term incentive compensation plan, the Company issued shares of unrestricted stock at approximately 26% of the Target.</footnote>
