Related Party Transactions	NOTE 6. RELATED PARTY TRANSACTIONS Founder Shares In February 2020, the Sponsor purchased 8,625,000 shares (the “Founder Shares”) of the Company’s Class B common stock for an aggregate price of $25,000. In April 2020, the Sponsor transferred 25,000 Founder Shares to each of the Company’s director nominees, for a total amount of 75,000 Founder Shares transferred. On May 20, 2020, the Company effected a stock dividend of 1,725,000 shares with respect to the Class B common stock, resulting in the initial stockholders holding an aggregate of 10,350,000 Founder Shares. All share and per-share amounts have been retroactively restated to reflect the stock dividend. The Founder Shares will automatically convert into shares of Class A common stock at the time of a business combination, on a one-for-one basis, subject to certain adjustments, as described in Note 9. The Founder Shares included an aggregate of up to 1,350,000 shares of Class B common stock subject to forfeiture by the Sponsor to the extent that the underwriters’ over-allotment was not exercised in full or in part, so that the number of Founder Shares would collectively represent approximately 20% of the Company’s issued and outstanding shares after the Initial Public Offering. As a result of the underwriters’ election to partially exercise their over-allotment option on June 9, 2020 and their election to exercise their remaining over-allotment option on June 26, 2020, the 1,350,000 Founder Shares are no longer subject to forfeiture. The Sponsor has agreed, subject to certain limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier of (A) one year after the completion of a business combination and (B) subsequent to a business combination, (x) if the last reported sale price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30‑trading day period commencing at least 150 days after a business combination, or (y) the date on which the Company completes a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Class A common stock for cash, securities or other property. Promissory Note—Related Party On February 12, 2020, the Sponsor issued an unsecured promissory note to the Company (the “Promissory Note”), pursuant to which the Company could borrow up to an aggregate principal amount of $300,000. The Promissory Note was non-interest bearing and payable on the earlier of December 31, 2020 or the consummation of the Initial Public Offering. As of May 26, 2020, there was $191,000 outstanding under the Promissory Note, of which such amount was repaid on May 27, 2020. Related Party Loans In addition, in order to finance transaction costs in connection with a business combination, the Sponsor, an affiliate of the Sponsor, or certain of the Company’s officers and directors or their affiliates was entitled to, but was not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a business combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a business combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a business combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such Working Capital Loans may be convertible into warrants of the post business combination entity. The warrants would be identical to the Private Placement Warrants. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of December 31, 2020, no Working Capital Loans were outstanding. Administrative Support Agreement The Company entered into an agreement whereby, commencing on May 26, 2020 through the earlier of the Company’s consummation of a business combination or its liquidation, the Company agreed to pay an affiliate of the Sponsor a total of $10,000 per month for office space, utilities, administrative and support services. For the period from February 4, 2020 (inception) through December 31, 2020, the Company incurred and paid $70,000 in fees for these services.
