Share-Based Payment Arrangement [Abstract] |
Schedule of share-based payment arrangement by share-based payment award, performance criteria | The table below outlines the performance criteria and their respective weightings for the LTI performance plans granted in 2025.
LTI performance plan criteria | Market/Non-market element | Weight
Relative TSR | Market | 25%
Strategic value drivers | Non-market | 35%
Technology Leadership Index | Non-market | 20%
ESG measures | Non-market | 20%
Total |  | 100%
Following the US executive order 14173, the non-financial ESG performance metrics were modified as follows: •For the employees based in the US, the gender diversity performance measures are omitted, and an increased weighting is applied on the Employee engagement and Inclusion score (13.33%), and •For the employees outside the US, the gender diversity performance measures are calculated excluding US employees. All employees who are eligible for the LTI plan 2023-2025 and 2024-2026 will be impacted by this modification. There are no incremental fair value and no incremental compensation costs arising from the modifications.
