Net Loss per Common Share |
Net Loss Per Share | 5. Net Loss per Common Share The Company calculates net loss per common share in accordance with ASC 260 “Earnings Per Share” (“ASC 260”). Basic and diluted net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. During 2022 and 2023, the Company calculated loss per share using the two-class method. The two-class method is an allocation formula that determines loss per share for each share of common stock and redeemable common stock (see note 11), a participating security, according to dividends declared and participation rights in undistributed earnings. ​
