Confidentiality
All information supplied is treated as strictly confidential and is used solely for the purpose of calculating maintenance ratios. The information is used to generate the ratios listed in the specific report for each site and to generate the aggregate (mean etc) ratios which appear in all reports.

Site specific information only appears in the report for that specific site and it is not possible to derive individual ratios or source data supplied by any site from the aggregated information. Participating sites will be listed in the comparison reports so that everybody can see who is included in the comparison. Where the comparison is broken down into smaller groups based on industry or manufacturing technology, the sites in each group will be listed. However, the size of these groups will be sufficiently large to make average results meaningful and care will be taken to ensure that no one site’s figures can be inferred from the results for the group.

Under no circumstances will the data or results for any site be communicated to any other company.
