Schedule of Assumptions | The weighted average grant date fair value was estimated using the Black-Scholes option-pricing model (level 3) with the following assumptions:
| Year Ended December 31, 2017
Expected volatility (1) | 0.2746%
Expected dividend yield (2) | —%
Expected option term (3) | 6.24 years
Risk-free rate (4) | 2.09%
(1) | The expected volatility assumption was calculated based on a peer group analysis of stock price volatility with a look back period based on the expected term and ending on the grant date.
(2) | As of December 31, 2017, the Company has not paid any dividends on our common stock. As of the stock option grant date, the Company does not anticipate paying any dividends on common stock over the term of the stock options. Option holders have no right to dividends prior to the exercise of the options.
(3) | The Company utilized the simplified method to determine the expected term of the stock options since the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term.
(4) | The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant which corresponds to the expected term of the stock options.
Summary of the Activity of Unvested Stock Options | The following table summarizes the activity of the Company’s unvested stock options for the year ended December 31, 2017 (Successor):
