LEGALCERTIFICATIONOFACCOUNTSANDAUDITREPORTONCONSOLIDATEDFINANCIAL INFORMATION 5 As part of an audit in accordance with ISAs, we exercise professional judgment and maintain professional skepticism throughout the audit. We also:  identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations or the override of internal control;  obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control;  evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management;  conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors’ report. However, future events or conditions may cause the Group to cease to continue as a going concern;  evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and the events in a manner that achieves fair presentation;  obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion;  communicate with those charged with governance, including the supervisory body, regarding, among other matters, the planned scope and timing of the audit, and significant audit findings including any significant deficiencies in internal control that we identify during our audit;  determine, from the matters communicated with those charged with governance, including the supervisory body, those matters that were of most significance in the audit of the consolidated financial statements of the current year and are therefore the key audit matters. We describe these matters in our auditors’ report unless law or regulation precludes their public disclosure; and,  provide the supervisory body with a statement that we have complied with the relevant ethical requirements regarding independence, and communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards. Our responsibility also includes the verification that the information contained in the consolidated management report is consistent with the consolidated financial statements, and the verification of the requirements as provided in numbers 4 and 5 of article 451 of the Portuguese Companies’ Code regarding the corporate governance report, as well as the verification that the non-financial statement and the remunerations report were presented. 430
