In those reporting periods in which the Company has reported net income, anti-dilutive shares include those stock options that either have an exercise price above the average stock price for the period or the stock options’ combined exercise price and average unrecognized stock compensation expense upon exercise is greater than the average stock price. In those reporting periods in which the Company has a net loss, anti-dilutive shares are comprised of the impact of those number of shares that would have been dilutive had the Company had net income plus the number of common stock equivalents that would be anti-dilutive had the company had net income.
