We got a number of questions about finding the auditor for non-US firms. This sounds very easy, but unfortunately it’s not available in our databases – they only give the current or last known auditor.
There is one option, but it will involve a lot of manual labor. Company.INFO, a database with annual reports, shows the name of the auditor next to the link to the annual report – see the example. You have to search by name in this database.
For US companies this variable is easier to find: in CompuStat North America or in Audit Analytics, a database with detailed audit information.
