Redeemable Warrant Liability [Abstract]
Redeemable Warrant Liability	NOTE 7—REDEEMABLE WARRANT LIABILITY Pursuant to the Initial Public Offering, the Company sold 40,250,000 SAILSM securities (including the full exercise of the underwriter’s over-allotment option) at a price of $10.00 per SAILSM security. Each SAILSM security consists of one share of Class A common stock of the Company at $0.0001 par value and one-fourth of one Redeemable Warrant (or 10,062,500 Redeemable Warrants in the aggregate). See “Note 3—Initial Public Offering” for additional details on the Redeemable Warrants. The Company determined that the Redeemable Warrants qualified as freestanding financial instruments that are bifurcated from the Class A common stock and classified as a separate liability pursuant to ASC 815, “Derivatives and Hedging” (ASC 815). According to ASC 815, financial instruments classified as liabilities are presented at fair value each reporting period, with changes in fair value recorded through earnings. As of September 30, 2021 and December 31, 2020, the value of the Redeemable Warrants was $16,603,125 and $18,716,250, respectively. The Company recorded a gain on the change in fair value of the Redeemable Warrants of $2,113,125 for the nine months ended September 30, 2021, and a loss on the change in fair value of the Redeemable Warrants of $5,735,625 for the three months ended September 30, 2021, in the Change in fair value of redeemable warrant liability line in the Statement of Operations. As the Redeemable Warrants, effective February 1, 2021, are separately traded on the NYSE under the symbol “CBAH WS,” as of September 30, 2021, the fair value of the Redeemable Warrants was determined based on the quoted trading price of these instruments. As of December 31, 2020, the fair value of these instruments was estimated using Monte Carlo simulation. The key assumptions in the option pricing model utilized are assumptions related to expected underlying share-price volatility, expected term of the warrants, the risk-free interest rate and the Company’s dividend yield. The expected volatility as of the December 15, 2020 issuance date was derived from observable public warrant pricing on comparable ‘blank-check’ companies that went public in 2019 and 2020. The risk-free interest rate is based on the interpolated U.S. Constant Maturity Treasury yield. The expected term of the warrants is assumed to be one year until the closing of a Business Combination, and an estimated five year holding period, based on typical equity investor holding periods. The dividend rate is based on the historical rate, which the Company anticipates to remain at zero.
