Share-Based Compensation [Abstract]

Share-Based Compensation Policy

We determine the assumptions used in the valuation of option awards as of the date of grant. Differences in the stock price volatility, expected term or risk-free interest rate may necessitate distinct valuation assumptions at each grant date. As such, we may use different assumptions for options granted throughout the year. Option awards are granted with an exercise price equal to the closing market price of our common stock at the date of grant.We have never paid any cash dividends on our common stock and we have no present intention to pay a dividend; therefore, we assume that no dividends will be paid over the expected terms of option awards.
