Corrections
Email [email protected].
Corrections are the most useful messages we receive. To help us check and fix an error quickly, please include:
- the page address where the error appears;
- the figure or statement that is wrong;
- the correct value, and the filing or announcement that shows it, with a link (an SEC accession number or an RNS headline and date is ideal);
- the as-of date you are working from, if the figure changes over time.
Every correction is checked against the source document before the site is changed. Material corrections are noted on the affected page. The methodology explains how corrections are recorded.
Everything else
Email [email protected] for:
- questions about how a figure was calculated;
- suggestions for instruments, issuers or glossary terms to add;
- press enquiries;
- questions about reusing 21DC data, which is covered in the terms of use.
Privacy requests go to [email protected], as set out in the privacy notice.
