The corresponding marked performance indicators are also published at pages 24, 29, 30, 31 and 34 of the BAE Systems 2018 Annual Report and selected pages of the standalone CR Report.
 

What standards we used: basis of our work, criteria used and level of assurance

Our work was carried out by a multi-disciplinary team of CR and business ethics assurance specialists in accordance with International Standard on Assurance Engagements 3000 (ISAE 3000) (Revised). To achieve limited assurance ISAE 3000 (Revised) requires that we review the processes, systems and competencies used to compile the areas on which we provide assurance. This is designed to give a similar level of assurance to that obtained in the review of interim financial information. It does not include the detailed testing of source data or the operating effectiveness of processes or internal controls.
 
Our engagement provides limited assurance as defined in ISAE 3000. The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for, a reasonable assurance engagement and consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would have been obtained had a reasonable assurance engagement been performed.

 

For the selected CR performance indicators we planned and performed the work to provide limited assurance as to whether the BAE Systems’ data on the webpage http://www.baesystems.com/en/our-company/corporate-responsibility, indicated with a footnote, corresponding performance indicators at pages 24, 29, 30, 31 and 34 of the BAE Systems 2018 Annual Report and selected pages of the standalone CR Report, are not materially misstated.

The basis of reporting for each assured indicator as noted above is provided at:  www.baesystems.com/2018basisofreporting and should be read in conjunction with the indicators and associated statements reported on BAE Systems’ website.

What we did: limited assurance procedures performed

Considering the risk of material error, we planned and performed the work to obtain all the information and explanations considered necessary to provide sufficient evidence to support our assurance conclusion. The key procedures we carried out included:

  • Interviewing managers at BAE Systems’ head office, including the CR team and those with responsibility for CR management and Group CR reporting
  • Analysing and reviewing on a sample basis the key structures, systems, processes, procedures and controls relating to the Group level collation, validation and reporting of CR performance data including:
    • The collection, collation, validation and reporting of selected environmental, business conduct, safety, diversity and community investment performance data at the year end.
    • Using questionnaires to survey a limited purpose non-statistical sample of sites to gain an understanding of key processes and controls for reporting selected performance data to the Group CR team. Sites were selected based on environmental and safety performance, materiality to the Group and inherent risk of location. We did not perform any site visits during our work.
    • Examining underlying documents to corroborate questionnaire outcomes and to inform our assessment of the subject matter to be assured.
    • Performing limited purpose non-statistical sample testing to verify that data has been appropriately captured, investigated, categorised and reported.
    • With regard to the recordable injuries safety data, our testing comprised an assessment of the understanding of relevant policy and procedures held by a sample of Site Safety Leads, rather than a qualitative reassessment of non-major incidents and the underlying injuries.
  • Understood and analysed on a non-statistical sample basis the collation, validation and reporting of selected CR performance data at Group level as indicated by corresponding footnotes is provided at http://www.baesystems.com/en/our-company/corporate-responsibility, in accordance with their definitions and basis of reporting.
  • Reviewed the content of the CR section of the Annual Report 2018 and CR content of the website against the findings of the aforementioned procedures.

Limitations

In relation to our work performed on the CR performance indicators for 2018, we note the following specific limitations:

  • With regard to GHG emissions data, testing was carried out on the sites that were included on the BAE Systems internal environment management system. These represented 91% of reported emissions in 2018. The remaining 9% of reported emissions consisted of estimated data for sites which were not tested for accuracy and completeness.

What we found: our assurance conclusion

Limited assurance conclusion:
Based on the assurance work performed nothing has come to our attention to suggest that the environmental, business conduct, safety, diversity and inclusion and community investment performance indicators on the webpage, http://www.baesystems.com/en/our-company/corporate-responsibility, denoted with accompanying footnotes, and the corresponding marked performance indicators at pages 24, 29, 30, 31 and 34 of the BAE Systems 2018 Annual Report and selected pages of the standalone CR Report, are in all material aspects, not fairly stated.
