8. Loss per share of common stock

Basic loss per share is derived by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during each period. Diluted loss per share includes the effect, if any, of the potential exercise or conversion of securities, such as warrants and stock options, which would result in the issuance of incremental shares of common stock unless such effect is anti-dilutive. In calculating the basic and diluted net loss per share applicable to common stockholders, the weighted average number of shares remained the same for both calculations because when a net loss exists, dilutive shares are not included in the calculation. Potentially dilutive securities outstanding, as determined by the latest applicable conversion price, that have been excluded from diluted loss per share due to being anti-dilutive include the following:
