Our assurance activities Considering the level of assurance and our assessment of the risk of material misstatement of the Report a multi-disciplinary team of sustainability and assurance specialists performed a range of procedures that included, but was not restricted to, the following: • Assessing the appropriateness of the reporting criteria for the Report. • Interviews with relevant staff to understand and evaluate the relevant management systems and processes (including internal review and control processes) used for collecting and reporting the selected disclosures. • A review at corporate level of a sample of qualitative and quantitative evidence supporting the reported information. • An analytical review of the year-end data submitted by all locations included in the consolidated 2022 group data for the selected disclosures which included testing the completeness and mathematical accuracy of conversions and calculations, and consolidation in line with the stated reporting boundary. • In person site visit to one Arxada facility in Switzerland to review source data and local reporting systems and controls. • Confirming conversion and emission factors and assumptions used. • Reviewing the presentation of information relevant to the scope of our work in the Report to ensure consistency with our findings. The limitations of our engagement The reliability of the assured information is subject to inherent uncertainties, given the available methods for determining, calculating, or estimating the underlying information.
