For the years ended December 31, 2017, 2016 and 2015 the Company recognized compensation expense related to stock option grants of approximately $0.1 million, $0.2 million and $0.3 million, respectively.

No dividend yield was assumed because the Company has never paid a cash dividend on its common stock and does not expect to pay dividends in the foreseeable future. Volatilities were developed using the Company’s historical volatility. The risk-free interest rate was developed using the U.S. Treasury yield for periods equal to the expected life of the stock options on the grant date. The expected option term is based on actual historical results.
