| Reverse stock split description | on April 6, 2023, the Company's board of directors (the “Board”) approved a discretionary reverse stock split of the Company’s common stock in the range of 1-for‑15 shares and 1‑for-25 shares (the “Reverse Stock Split”), subject to stockholder approval at the Company’s annual meeting of stockholders held on May 19, 2023 (the “Annual Meeting”). At the Annual Meeting, the stockholders approved the Reverse Stock Split at a ratio in the range of 1-for-15 to 1-for-25, with such ratio to be determined at the discretion of the Board. On May 19, 2023, the Board approved a reverse stock split of 1-for-20 to also be effective as of May 19, 2023. As a result of the Reverse Stock Split, every 20 shares of the Company’s issued and outstanding common stock was automatically combined into one issued and outstanding share of common stock, without any change in the par value per share. No fractional shares were issued as a result of the Reverse Stock Split. Instead, any fractional shares of Common Stock that would have otherwise resulted from the Reverse Stock Split were rounded up to the nearest whole share. The Certificate of Amendment did not amend the number of authorized shares of common stock, which remained unchanged at 100,000,000 shares. The common stock began trading on a post-split basis on Nasdaq as of the open of trading on May 23, 2023.Proportionate adjustments were made to the exercise price and number of shares issuable upon the exercise of the options outstanding under the Company’s equity incentive plans, and the number of shares subject to restricted stock units (“RSUs”), deferred stock units (“DSUs”) and performance stock units (“PSUs”) under the Company’s equity incentive plans. All references to common stock, equity-based common stock awards and all share and per share data contained in this Quarterly Report on Form 10-Q (this “Form 10-Q”) have been adjusted to reflect the Reverse Stock Split unless explicitly stated otherwise. | |||||
