Equity [Abstract] |
Stockholders' equity | Stockholders' equity Redeemable convertible preferred stock Upon the closing of the IPO, all outstanding shares of the Company's redeemable convertible preferred stock automatically converted into 32,482,590 shares of common stock on a one-for-one basis. Additionally, upon completion of the IPO, the Company's authorized capital stock consisted of 500,000,000 shares of common stock, $0.001 par value per share and 10,000,000 shares of "blank check" preferred stock, $0.001 par value per share. Share repurchase program On September 3, 2019, the Company announced that its Board of Directors has authorized a common stock repurchase program of up to $50.0 million. No shares of the Company's stock were repurchased under this program during fiscal 2019. The Company withholds shares of common stock from certain employees in connection with the vesting of restricted stock unit awards issued to such employees to satisfy applicable tax withholding requirements. Such withheld shares are treated as common stock repurchases in our consolidated financial statements as they reduce the number of shares that would have been issued upon vesting. Repurchases associated with tax withholdings were not material during fiscal 2019.
