In connection with certain of its redeemable convertible preferred stock issuances, convertible debt financings, and other financing arrangements the Company issued warrants for shares of its common stock and various issues of its redeemable convertible preferred stock. Such warrants related to its redeemable convertible preferred stock were recorded as liabilities as a result of non-standard anti-dilution and redemption rights of the underlying stock and were carried at their estimated fair value using the Monte Carlo valuation model. In connection with the Company’s IPO, the warrants were converted to common stock warrants with no anti-dilution features. The Company revalued the warrants as of the offering date, recorded a gain on the liability through the Statements of Operations, and subsequently reclassified the warrant liability to additional paid-in-capital.
All common stock warrants outstanding convert on a one-to-one basis to common stock.
