- Definition

The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.

Share-Based Compensation Arrangement by Share-Based Payment Award, Plan Modification, Description and Terms			were 630,571 PSUs classified as liabilities in which the vesting occurs upon the achievement of specific performance-based conditions related to the Company’s financial performance over a three-year period, modified based on the Company’s Relative Total Shareholder Return (TSR) and subject to final vesting based on the participant’s continued employment through the end of the requisite service periods. The ultimate amount to vest may be downwardly adjusted by the Compensation Committee of the Company’s Board of Directors if the TSR is negative. The amount of awards that will ultimately vest for these PSUs can range from 0% to 200% based on the TSR calculated over a three-year period beginning January 1 of the year each grant was made. The Company currently expects that these PSUs will vest between 95% and 128%. The fair value of these PSUs will be remeasured at each period-end until the earlier of the date they are reclassified to equity or the vesting date. The inputs and assumptions used to calculate the fair value ranged from a remaining term of 1.50 to 2.50 years, risk-free interest rate of 2.11% to 2.39%, the expected volatility of 58.2% to 89.3%, and the expected dividend yield of 0.0%. In addition, there are 725,000 PSUs classified as liabilities in which the vesting occurs upon the achievement of specific performance-based conditions related to the Company’s financial performance over a two-year period, subject to various subjective individual performance goals and subject to final vesting based on the participant’s continued employment through the end of the requisite service periods. The fair value of these PSUs will be remeasured at each period-end until the earlier of the date they are reclassified to equity or the vesting date. The Company currently expects that these PSUs will vest at 100%. The fair value is equal to the market value of the common stock at each period-end.
