SHARE-BASED PAYMENTS (CONTINUED) (d) Performance rights (Rights) (continued) Valuation of share-based payments The fair value of the equity-settled share-based payments granted under the ESOP is estimated at the date of grant using either a Black & Scholes or a Monte Carlo model, which takes into account factors including the exercise price, the volatility of the underlying share price, the risk-free interest rate, the market price of the underlying share at grant date, historical and expected dividends and the expected life of the option or right, and the probability of fulfilling the required hurdles. – Tranche 5 Rights vest subject to performance hurdles, measured for the period 1 July 2021 to 30 June 2024 – Tranche 6 Rights vest subject to performance hurdles, measured for the period 1 July 2022 to 30 June 2025 – Tranche 7 Rights vest subject to performance hurdles, measured for the period 1 July 2023 to 30 June 2026 The following table gives the assumptions made in determining the fair value of the rights granted in Tranche 7.

The expected volatility was determined using a historical sample of the Company’s share price over a three-year period. The resulting expected volatility therefore reflects the assumptions that the historical volatility is indicative of future trends, which may also not necessarily be the actual outcome. 29.
