The Group operates four principal shared service centres (both in-house and outsourced) in the UK, Malaysia, Romania and India, which process a substantial proportion of the Group’s transactions. The outputs from the shared service centres are included in the financial information of the reporting components they service and therefore they are not separate reporting components. Each of the service centres is subject to specified risk-focused audit procedures, predominantly the testing of transaction processing and review controls. Additional procedures are performed by component audit teams at certain reporting components to address the audit risks not covered by the work performed over the shared service centres. These procedures are designed to address the risk of material misstatement identified through our group risk assessment processes.
