10. Net Loss per Share

Basic net loss per share is calculated by dividing the net loss by the weighted average number of shares of common stock outstanding for the period, without consideration for common stock equivalents. The Company’s potentially dilutive shares, which include outstanding stock options, are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

Options to purchase 2,184,504 and 1,405,275 shares of common stock were excluded from the calculation of net loss per share as of September 30, 2019 and 2018, respectively, due to their anti-dilutive effect.
