Auditor’s responsibilities for the audit of the separate and consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the separate and consolidated financialstatements as a whole are free from material misstatement, whether due to fraud or error, and to issue anauditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not aguarantee that an audit conducted in accordance with ISAs will always detect a material misstatement when itexists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate,they could reasonably be expected to influence the economic decisions of users taken on the basis of theseseparate and consolidated financial statements.

As part of an audit in accordance with ISAs, we exercise professional judgment and maintain professionalscepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the separate and consolidated financial statements,whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtainaudit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detectinga material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involvecollusion, 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 areappropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of theCompany’s and Group’s internal control.
• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates andrelated disclosures made by the Board of Directors.
• Conclude on the appropriateness of Board of Directors’ use of the going concern basis of accounting and,based on the audit evidence obtained, whether a material uncertainty exists related to events or conditionsthat may cast significant doubt on the Company’s and Group’s ability to continue as a going concern. If weconclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to therelated disclosures in the separate and consolidated financial statements or, if such disclosures areinadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the dateof our auditor’s report. However, future events or conditions may cause the Company and Group to cease tocontinue as a going concern.
• Evaluate the overall presentation, structure and content of the separate and consolidated financialstatements, including the disclosures, and whether the separate and consolidated financial statementsrepresent the underlying transactions and events in a manner that achieves fair presentation.
• Obtain sufficient appropriate audit evidence regarding the financial information of the entities or businessactivities within the Group to express an opinion on the consolidated financial statements. We are responsiblefor the direction, supervision and performance of the Company and Group audit. We remain solelyresponsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope andtiming of the audit and significant audit findings, including any significant deficiencies in internal control thatwe identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethicalrequirements regarding independence, and to communicate with them all relationships and other matters thatmay reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were ofmost significance in the audit of the separate and consolidated financial statements of the current period and aretherefore the key audit matters. We describe these matters in our auditor’s report.
