Accounting Changes and Error Corrections [Abstract] |
Unaudited Selected Quarterly Financial Information | Unaudited Selected Quarterly Financial Information As previously disclosed on February 17, 2023 and February 27, 2023, in connection with the preparation of our consolidated financial statements for the year ended December 31, 2022, we identified tax errors within our previously issued unaudited condensed consolidated financial statements as of and for the quarterly and year to date periods ended March 31, 2022, (“Q1 2022”), June 30, 2022 (“Q2 2022”), and September 30, 2022 (“Q3 2022”) as included in our previously filed Quarterly Reports on Form 10-Q. Specifically, within our income tax provision there was an error relating to the identification of named executive officers subject to limitation on the deductibility of executive compensation under Internal Revenue Code Section 162(m), or Section 162(m). As a result of this error, Q1 2022 deferred tax assets were understated and the provision for income taxes was overstated by $3.9 million, reflecting a discrete impact of $2.4 million and a $1.5 million impact resulting from the error in the annual effective tax rate. The Section 162(m) error also had the impact of a $0.2 million understatement of the benefit for income taxes and a $4.1 million overstatement of the provision for income taxes for the three and six months ended June 30, 2022, respectively, and a $1.2 million overstatement of the benefit for income taxes and a $2.8 million overstatement of the provision for income taxes for the three and nine months ended September 30, 2022, respectively, and the associated impacts on deferred tax assets. Management has concluded that such errors resulted in the previously issued Q1 2022, Q2 2022, and Q3 2022 unaudited condensed consolidated financial statements, including the respective year-to-date periods, being materially misstated and therefore require restatement. In connection with the tax errors noted above, we are also correcting other previously identified immaterial errors related to: i) $1.2 million of revenue and $0.2 million of associated costs of revenue, that should have been recognized in Q1 2022, and which was initially corrected for as an out of period correction in Q2 2022; ii) $1.2 million of a late customer acquisition marketing, or CAM credit, that should have been recognized as a reduction to sales and marketing expense in Q2 2022, and which was initially corrected for as an out of period adjustment in Q3 2022; and iii) $0.9 million of revenue and $0.3 million of associated costs of revenue that should have been recognized in Q3 2022. The following table presents summarized unaudited consolidated quarterly financial information for each of the quarters in the year ended December 31, 2022 (in thousands, except per share amounts):
