Notes:
These firms are excluded from the sample, as market values no longer reflect investors’ reactions to accounting information when trading in a firm’s shares is suspended.
Steinhoff International Holdings NV represents a major corporate fraud in South Africa. As the accounting data on the database has been replaced with the restated financial statement data, the historic market value no longer reflects investors’ reactions to the accounting information.
Where a firm has not been listed for a full sample year, the database adjusts the reported numbers to annual results for that year. This adjustment is not possible for hand-collected earnings data, and therefore, these observations are excluded from the sample.
Historic results announcements are sometimes not retained by data providers so that hand-collection of the required data items is not possible
