Summary of Significant Accounting Policies | Note 2—Summary of Significant Accounting Policies Basis of Presentation The Company’s unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the SEC for interim financial information and the instructions to Form 10-Q. Certain disclosures included in the annual financial statements have been condensed or omitted from these financial statements as they are not required for interim financial statements under U.S. GAAP and the rules of the SEC. These unaudited condensed financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These adjustments are of a normal, recurring nature. Interim period operating results may not be indicative of the operating results for a full year. The accompanying unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s restated Annual Report on Form 10-K/A for the year ended December 31, 2020. Emerging Growth Company Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and on deposit at banking institutions as well as all highly liquid short-term investments with original maturities of ninety (90) days or less. As of June 30, 2021, the Company held deposits of $799,624 in a custodian account and $750,085,956 in Goldman Sachs Financial Square Treasury Instruments Fund, a money market fund managed by an affiliate of the Sponsor. Money market funds are characterized as Level I investments within the fair value hierarchy under ASC 820 (as defined below). The cash held in the money market account is considered restricted. Dividend income from money market funds is recognized on an accrual basis. Redeemable Shares of Class A Common Stock As discussed in Note 1, all of the 75,000,000 shares of Class A common stock sold as parts of the Units in the Public Offering contain a redemption feature. In accordance with the Accounting Standards Codification 480-10-S99-3A - “Classification and Measurement of Redeemable Securities”, redemption provisions not solely within the control of the Company require the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. The Company classifies all shares of Class A common stock as redeemable. Net Income Per Common Share Net income per share of common stock is computed by dividing net income by the weighted average number of common shares outstanding during the period. The Company applies the two-class method in calculating earnings per share. Accretion associated with the redeemable shares of Class A common stock is excluded from earnings per share as the redemption value exceeds fair value. As of June 30, 2021, the Company had outstanding warrants to purchase up to 27,250,000 shares of Class A common stock. The weighted average of these shares was excluded from the calculation of diluted net income per share of common stock since the exercise of the warrants is contingent upon the occurrence of future events. As of June 30, 2021, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted net income per share of common stock is the same as basic net income per share of common stock for the period. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the Accounting Standards Codification 820 (“ASC 820”), “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheets, primarily due to their short term nature. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. One of the more significant accounting estimates included in these financial statements is the determination of the fair value of the warrant liability. Such estimates may be subject to change as more current information becomes available and accordingly, the actual results could differ significantly from those estimates. Warrant Liability The Company accounts for the warrants in accordance with the guidance contained in Accounting Standards Codification 815 (“ASC 815”), “Derivatives and Hedging”, under which the warrants do not meet the criteria for equity treatment and must be recorded as derivative liabilities. Accordingly, the Company classifies the warrants as liabilities at their fair value and adjusts the warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the warrants are exercised or expire, and any change in fair value is recognized in the Company’s statement of operations. The fair value of the Private Placement Warrants (as defined in Note 4) has been estimated using a Black- Scholes-Merton model and the fair value of the Public Warrants (as defined in Note 3) issued in connection with the Public Offering has been measured based on the listed market price of such Public Warrants (see Note 6). Income Taxes The Company is taxed as a corporation for U.S. federal income tax purposes. As a corporation, for tax purposes, the Company is subject to U.S. federal and various state and local income taxes on its earnings. Prior to July 2020, the Company was included with The Goldman Sachs Group Inc. and subsidiaries (the “Group Inc.”) in the consolidated corporate federal income tax return as well as consolidated/combined state and local tax returns. The Company computed its tax liability on a modified separate company basis and will settle such liability with the Group Inc. pursuant to a tax sharing arrangement. To the extent the Company generates tax benefits from losses during such time that it is consolidated with the Group Inc., the amounts will be reimbursed by the Group Inc., pursuant to the tax sharing arrangement. The Company’s state and local tax liabilities are allocated to reflect its share of the consolidated/combined state and local income tax liability. Following changes in ownership starting July 2020, the Company deconsolidated from the Group Inc. for tax purposes and the tax sharing arrangement with the Group Inc. was terminated. As of July 2020, the Company filed separate corporate federal and state and local income tax returns. To the extent the Company generates tax losses after it ceases being consolidated with the Group Inc., tax benefits from losses will be accrued if it is more likely than not the losses may be carried forward and utilized against future expected profits. Income taxes are provided for using the assets and liabilities method under which deferred tax assets and liabilities are recognized for temporary differences between the financial reporting and tax bases of assets and liabilities. Deferred Income Taxes The Company follows the asset and liability method of accounting for income taxes under Accounting Standards Codification 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Unrecognized Tax Benefits The Company recognizes tax positions in the financial statements only when it is more likely than not that the position will be sustained on examination by the relevant taxing authority based on the technical merits of the position. A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the financial statements. There were no unrecognized tax benefits as of June 30, 2021. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for interest expense and penalties related to income tax matters as of June 30, 2021 and December 31, 2020. The Company is subject to income tax examinations by major taxing authorities since inception. Profit Interests Membership interests issued by the Sponsor as profits interests (see Note 4) represent compensation to certain individuals for services the Company receives from these individuals through closing of the Business Combination. Although the Company is not a direct party to the profits interests, it attributes compensation expense equal to the change in the fair value of these arrangements. There was no impact of compensation expense attribution for the three months or six months ended June 2021 or June 2020. Subscription Agreements The Subscription Agreements (see Note 1) involve only physical settlement in a fixed number, it qualifies for equity classification under Accounting Standards Codification 815 (“ASC 815”), “Derivatives and Hedging”, and, therefore, is not periodically remeasured to fair value. Backstop Agreement The Backstop Agreement (see Note 1) involves a conditional obligation that the Company must settle by issuing a variable number of its shares, where the monetary value is predominantly based on variations in something other than the fair value of the Company’s shares, it is initially and subsequently measured at fair value under ASC 480. Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements. | Note 3—Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America and pursuant to the accounting and disclosure rules and regulations of the SEC. Emerging Growth Company Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards.

The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Net Loss Per Common Share Net loss per share of common stock is computed by dividing net loss by the weighted average number of common shares outstanding during the period. The Company applies the two-class method in calculating earnings per share. Accretion associated with the redeemable shares of Class A common stock is excluded from EPS as the redemption value approximates fair value. At December 31, 2020, the Company had outstanding warrants to purchase of up to 27,250,000 shares of Class A common stock. The weighted average of these shares was excluded from the calculation of diluted net loss per share of common stock since the exercise of the Warrants is contingent upon the occurrence of future events. As of December 31, 2020, the Company did not have any dilutive securities or other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted net loss per share of common stock is the same as basic net loss per share of common stock for the period. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and on deposit at banking institutions as well as all highly liquid short-term investments with original maturities of ninety (90) days or less. As of December 31, 2020, the Company held deposits of $383,246 at custodian account and $750,063,158 in Goldman Sachs Financial Square Treasury Instruments Fund, a money market fund managed by an affiliate of the Sponsor. Money market funds are characterized as Level I investments within the fair value hierarchy under ASC 820 (as defined below). The cash held in the money market account is considered restricted. Dividend income from money market funds is recognized on an accrual basis. Redeemable Shares of Class A Common Stock As discussed in Note 1, all of the 75,000,000 shares of Class A common stock sold as parts of the Units in the Public Offering contain a redemption feature. In accordance with the Accounting Standards Codification 480-10-S99-3A “Classification and Measurement of Redeemable Securities”, redemption provisions not solely within the control of the Company require the security to be classified outside of permanent equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480. The Company had previously classified 3,133,926 shares of Class A common stock as permanent equity. As part of the restatement of the Company’s financial statements, the Company has classified all of the shares of Class A common stock as redeemable. Immediately upon the closing of the Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable shares of Class A common stock resulted in charges against additional paid-in capital and accumulated deficit. As of December 31, 2020, the shares of Class A common stock reflected on the balance sheet are reconciled in the following table:
|  | As of December 31, 2020 |
Gross proceeds |  | $ | 750,000,000 |
Less: |  |  |  |
Proceeds allocated to public warrants |  | $ | (19,587,038 | )

Accretion of carrying value to redemption value |  | $ | 60,750,262 |

Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under the Accounting Standards Codification 820 (“ASC 820”), “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheets, primarily due to their short term nature.

One of the more significant accounting estimates included in these financial statements is the determination of the fair value of the warrant liability. Such estimates may be subject to change as more current information becomes available, and accordingly the actual results could differ significantly from those estimates. Offering Costs The Company complies with the requirements of the Accounting Standards Codification 340-10-S99-1 and SEC Staff Accounting Bulletin Topic 5A—“Expenses of Offering.” The Company incurred offering costs in connection with its Public Offering of $988,245. These costs, together with the upfront underwriter discount and deferred underwriter discount, of $41,250,000 were allocated to the shares of Class A common stock and Public Warrants upon the closing of the Public Offering (as defined in Note 4). See Note 2 for further information about accounting for offering costs. Warrant Liability The Company accounts for the Warrants in accordance with the guidance contained in ASC 815 under which the Warrants do not meet the criteria for equity treatment and must be recorded as derivative liabilities. Accordingly, the Company classifies the Warrants as liabilities at their fair value and adjusts the Warrants to fair value at each reporting period. This liability is subject to re-measurement at each balance sheet date until the Warrants are exercised or expire, and any change in fair value is recognized in the Company’s statement of operations. The fair value of the Public Warrants was initially measured using a Monte Carlo simulation. The Public Warrants have subsequently been measured based on the listed market price. The fair value of the Private Warrants has been estimated using a Black-Scholes-Merton model since the initial measurement date. (see Note 7) Income Taxes The Company is taxed as a corporation for U.S. federal income tax purposes. As a corporation, for tax purposes, the Company is subject to U.S. federal and various state and local income taxes on its earnings. Prior to July 2020, the Company was included with The Goldman Sachs Group Inc. and subsidiaries (the “Group Inc.”) in the consolidated corporate federal income tax return as well as consolidated/ combined state and local tax returns.

The Company’s state and local tax liabilities are allocated to reflect its share of the consolidated/combined state and local income tax liability. Following changes in ownership starting July 2020, the Company deconsolidated from the Group Inc. for tax purposes and the tax sharing arrangement with the Group Inc. was terminated. Beginning July 2020, the Company will file separate corporate federal and state and local income tax returns. To the extent the Company generates tax losses after it ceases being consolidated with the Group Inc., tax benefits from losses will be accrued if it is more likely than not the losses may be carried forward and utilized against future expected profits. Income taxes are provided for using the assets and liabilities method under which deferred tax assets and liabilities are recognized for temporary differences between the financial reporting and tax bases of assets and liabilities. Deferred Income Taxes The Company follows the asset and liability method of accounting for income taxes under Accounting Standards Codification 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases.

A position that meets this standard is measured at the largest amount of benefit that will more likely than not be realized on settlement. A liability is established for differences between positions taken in a tax return and amounts recognized in the financial statements. There were no unrecognized tax benefits as of December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for interest expense and penalties related to income tax matters as of December 31, 2020, 2019 and 2018. The Company is subject to income tax examinations by major taxing authorities since Inception. Recent Accounting Pronouncements Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s financial statements.
