Net Loss Per Share |
Net Loss Per Share | Note 3—Net Loss Per Share Our potentially dilutive securities include potential common shares related to our stock options, warrant and unsecured convertible senior notes. Diluted earnings per share (“Diluted EPS”) considers the impact of potentially dilutive securities except in periods in which there is a loss because the inclusion of the potential common shares would have an anti-dilutive effect. Shares of our common stock issuable under the unsecured convertible notes are calculated using the if-converted method and are excluded from the below table as their impact is anti-dilutive. Diluted EPS excludes the impact of potential common shares related to our stock options in periods in which the option exercise price is greater than the average market price of our common stock for the period. Potentially dilutive securities excluded from Diluted EPS are as follows: ​
