Abstract

Purpose
It has been two decades since the first academic paper shone a spotlight on non-GAAP earnings. The past 20 years of research investigates concerns over the misuse of these disclosures and resulted in some significant changes to accounting and reporting standards across the globe. This paper aims to document the history of non-GAAP reporting and outline the emerging themes of the now matured practice of non-GAAP
reporting.

Design/methodology/approach
This systematic literature review searches two popular databases to identify the academic publications relating to non-GAAP reporting between 2002 and 2022. The paper uses bibliographic mapping to present the key statistics of the non-GAAP reporting field of research.

Findings
The non-GAAP reporting environment started out as the “wild West’ but, through regulation and public awareness, emerged as an important supplement to the traditional outputs of financial reporting. Current consensus is recent non-GAAP earnings are informative to users but there is lack of research into qualitative non-GAAP disclosures and the vast body of archival research needs triangulating with more experimental studies.

Originality/value
This paper contributes to the literature by documenting the past 20 years of non-GAAP reporting and identifying the important existing and emerging research areas concerning non-GAAP earnings disclosures.
