Conclusions relating to principal risks, going concern and viability statement We have nothing to report in respect of the following information in the annual report, in relation to which the ISAs (UK) require us to report to you whether we have anything material to add or draw attention to: • the disclosures in the annual report set out on page 57 that describe the principal risks and explain how they are being managed or mitigated; • the directors’ confirmation set out on page 113 in the annual report that they have carried out a robust assessment of the principal risks facing the entity, including those that would threaten its business model, future performance, solvency or liquidity; • the directors’ statement set out on page 114 in the annual report about whether they considered it appropriate to adopt the going concern basis of accounting in preparing the financial statements, and their identification of any material uncertainties to the entity’s ability to continue to do so over a period of at least twelve months from the date of approval of the financial statements; • whether the directors’ statement in relation to going concern required under the Listing Rules in accordance with Listing Rule 9.8.6R(3) is materially inconsistent with our knowledge obtained in the audit; or • the directors’ explanation set out on page 114 in the annual report as to how they have assessed the prospects of the entity, over what period they have done so and why they consider that period to be appropriate, and their statement as to whether they have a reasonable expectation that the entity will be able to continue in operation and meet its liabilities as they fall due over the period of their assessment, including any related disclosures drawing attention to any necessary qualifications or assumptions.

These matters included those which had the greatest effect on the overall audit strategy, the allocation of resources in the audit and in directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in our opinion thereon, and we do not provide a separate opinion on these matters.
