Schedule of assets measured using significant unobservable inputs

The following tables present a reconciliation of the opening to closing balance of assets measured using significant unobservable inputs (Level 3) as of the dates indicated (in millions):

	September 30, 2021		December 31, 2020
Opening balance at beginning of period	$	1,051	$	281
Change in fair value	383		770
Closing balance at end of period	$	1,434	$	1,051

The following table presents quantitative information about Level 3 significant unobservable inputs used in the fair value measurement of the warrant as of September 30, 2021 (in millions):

	Fair value		Valuation technique	Unobservable Input	Range (weighted average)(1)
Warrant	$	1,434	Black-Scholes and Monte Carlo	Probability of vesting	0.0% - 95.0% (71%)
				Equity volatility	24.5% - 61.7% (42%)

(1) Probability of vesting were weighted by the unadjusted value of the tranches. For volatility, the average represents the arithmetic average of the points within the range and is not weighted by the relative fair value or notional amount.
