The impact of the disclosure of non-GAAP earnings in Australian annual reports on non-sophisticated users

The disclosure of non-GAAP earnings in Australian annual reports has risen steadily in recent years. These non-statutory earnings measures are generally disclosed in the unaudited section of the annual report and are not consistent with statutory profit as defined under generally accepted Australian accounting standards (GAAP). Recent research conducted in the United States (US) has provided evidence that non-sophisticated investor decisions are influenced by the presence and prominence of non-GAAP earnings information. Further evidence suggests that investor perception changed after non-GAAP earnings disclosures became subject to regulation in that jurisdiction. Australia has high investor participation rates by international standards, including investors operating self-managed superannuation funds, resulting in a significant number of active individual investors. This study employs an experimental design to investigate the impact on non-sophisticated investors of the reporting of non-GAAP earnings information in addition to GAAP earnings information in Australian annual reports. The results of this study show a positive association between the prominent disclosure of non-GAAP earnings information and non-sophisticated investor reliance on this information. These results provide important evidence to Australian regulators as these narrative disclosures are not subject to regulation, in contrast to the US where mandatory regulation has been in place since 2003
