Accounting Changes and Error Corrections [Abstract] |
Correction of Immaterial Misstatements in the Financial Statements for the Year Ended December 31, 2018 | Correction of Immaterial Misstatements in the Financial Statements for the Year Ended December 31, 2018 During 2019, Company management identified immaterial misstatements in the financial statements for the year ended December 31, 2018 related to the carrying value of redeemable convertible preferred stock warrant liabilities. Based on a quantitative and qualitative analysis of the error as required by authoritative guidance, management concluded that the correction, which decreased the carrying value of the redeemable convertible preferred stock warrant liabilities with a corresponding decrease in net loss, had no material impact on the Company's previously issued financial statements as of and for the year ended December 31, 2018. These amounts have been adjusted in the accompanying balance sheet and statement of operations. The revision to the Company's previously reported balance sheet are identified in the table below:
