To: The management of Vodafone Libertel B.V.
The management of Vodafone Libertel B.V. (hereinafter: Vodafone) instructed us to perform an assurance engagement relating to Vodafone's 2011-2012 sustainability report (hereinafter: Report). Our assurance engagement aimed to obtain limited assurance that the information in the 2011-2012 sustainability report is, in all material respects, an reliable and adequate representation of the policy, business operations, performance and events during the 2011-2012 reporting year, which runs from 1 April 2011 to 31 March 2012.
The 2011-2012 GRI index is an integral part of the 2011-2012 sustainability report and therefore forms part of our engagement. Other references in the Report (to vodafone.nl, external websites and other documents) are out of scope for our engagement. No assurance is given in relation to comparative figures for non-financial data.
The Report contains forward-looking information in the form of ambitions, strategy, plans, forecasts and estimates. The fulfilment of such information is inherently uncertain. For that reason, we do not provide assurance relating to forward-looking information.
The management's responsibility
The management is responsible for the preparation of the Report in accordance with the Sustainability Reporting Guidelines of the Global Reporting Initiative (G3.1), the Guide to Sustainability Reporting of the Dutch Accounting Standards Board and Vodafone's reporting policy, including identifying stakeholders and determining material issues. The choices made by management, the scope of this report and the reporting policy are explained in the GRI index section of the Report. Furthermore management is responsible for such internal control as it determines is necessary to enable the preparation of the company financial statements that are free from material misstatement, whether due to fraud or error.
The auditor's responsibility
Our responsibility is to form a conclusion on the Report on the basis of our procedures. We performed our procedures relating to the Report in accordance with Dutch law, including Standard 3410N ‘Assurance engagements relating to sustainability reports’.
Our review comprised the following main procedures:
- testing the information contained in the Report against the criteria, in accordance with the ‘Sustainability Reporting Guidelines’ (G3.1) of the Global Reporting Initiative and the Guide to Sustainability Reporting of the Dutch Accounting Standards Board, that form part of Vodafone's reporting policy;
- obtaining an understanding of the sector, the organization and the relevant sustainability issues specific for the organization;
- obtaining an understanding of the design and existence of systems and methods used to collect and process data that serves as a basis for the reported information;
- assessing the plausibility of the information in the Report through a combination of analytical procedures and inquiries;
- interviews with responsible company officers;
- examining relevant company documents and consulting external sources;
- evaluating the acceptability of the reporting principles used and the reasonableness of estimates made during the preparation of the Report;
- evaluating the overall presentation of the Report.
The procedures performed in order to obtain limited assurance aim to verify the plausibility of information and are less extensive than those performed for assurance engagements aimed at obtaining reasonable assurance and therefore less assurance is provided.
We believe that the assurance evidence we have obtained is sufficient and appropriate to provide a basis for our conclusion.
Based on our procedures we conclude that nothing came to our attention that causes us to believe that the information in Vodafone's 2011-2012 sustainability report does not provide, in all material respects, a reliable and sufficient representation of the policy, business operations, performance and events during 2011-2012, in accordance with the guidelines of the Global Reporting Initiative, the Guide to Sustainability Reporting of the Dutch Accounting Standards Board and the documented reporting policy of Vodafone as included in the GRI matrix.
