The information content of mandatory and discretionary non-GAAP earnings

Abstract

PURPOSE – This paper aims to investigate the pricing of discretionary earnings in South Africa. This is a unique setting, as South African listed firms also reportmandatory non-GAAP earnings (“headline earnings”). DESIGN/METHODOLOGY/APPROACH – Results are based on multivariate regression analyses for South African firms that report from 2010 to 2019. FINDINGS – Findings show that the value-relevance of discretionary earnings exceeds that of both GAAP earnings and headline earnings. In addition, placement of discretionary earnings reconciliations communicates information about the decision-usefulness of earnings. ORIGINALITY/VALUE – Discretionary earnings remain the most value-relevant earnings measure, despite the divergent decision-useful characteristics offered by headline earnings and GAAP earnings. Therefore, the most decision-useful earnings reflect unique industry or firm characteristics rather than the assurance arising from regulation.
