Assurance 2015

Across the report our total community contribution and selected environmental performance information are externally assured, alongside our financial results. Other measures go through an internal assertion testing process by our Sustainability Services Team.

BDO LLP provides:

• Independent limited assurance in respect of selected environmental performance information contained in the Deloitte LLP Impact Report. BDO’s Independent Assurance Statement is available here together with Deloitte’s Basis for Reporting for the reporting period 1 June 2014 to 31 May 2015. We are acting upon BDO’s recommendations and the lessons learned are helping us to inform our future work.
• The financial performance information contained within this report is based on the financial statement audited by BDO LLP. The Report of the Independent Auditor is included here.

Our Community performance figures are calculated using the London Benchmarking Group Model.

Our Sustainability Services Team has performed a limited review on this report, tracing a sample of statements and figures back to the firm’s source data. This work does not constitute a complete review nor provide any assurance as to the accuracy or completeness of the reported information.
