Related Party Transactions [Abstract] |
Related Party Arrangements | Related Party Arrangements There were no new significant related party transactions for the year ended December 31, 2022. The Company entered into promissory note agreements in October 2018 which were fully repaid in August 2021. The promissory note agreements were entered into with two executive employees in conjunction with their early exercise of stock options to purchase 1,800,000 shares of the Company’s common stock. The principal amount of the notes was $3.1 million, and interest accrued at 2.83% on the outstanding principal amount annually. The notes were secured by the shares that were exercised. Based on the nonrecourse nature of these agreements, the agreements were accounted for as grants of options to purchase common stock. The fair value of the stock options, determined using the Black-Scholes option pricing model was being recognized over the requisite service period. The associated shares are legally outstanding and included in shares of common stock outstanding within the Consolidated Financial Statements, but were historically excluded from the Company’s net loss per common share calculations, as these shares of common stock were considered unvested until the underlying promissory notes were repaid. On August 23, 2021, the promissory notes were paid in full, including all accrued interest. After repayment of the loan, these shares are now considered outstanding for purposes of the Company’s net loss per common share calculations to the extent the shares are vested.
