What do auditors do?

An auditor specialises in examining and verifying a set of financial statements by reference to evidence (physical, oral, documentary, etc). When he/she are satisfied that the financial statements are true and fair, the auditor will issue a clean auditors' report; on the other hand, if the financial statements or the company are detected to show problems (e.g. show signs of fraudulent activity), the auditor's report will also make this clear.
