AGA 2021-1 and AGA 2021-bis plans are partially composed of AGAs subject to a market performance condition. AGAs 2022, AGAs 2023-1 and AGAs 2023-2 are not subject to a market performance condition. Accordingly, AGAs not subject to performance conditions are valued on the basis of the share price less future dividends, discounted at the risk-free rate. AGAs subject to performance conditions are valued using the same method, adjusted by a discount applied to reflect the performance condition. This discount is determined using the “Monte Carlo” analysis. The fair value at the grant date is different depending on whether the AGAs are subject to market performance conditions.
