Related-party transactions: a review of the regulation, governance and auditing literature

Abstract

Purpose Several studies, especially in Asian economies, have investigated the antecedents, implications and consequences of related-party transactions (RPTs). This paper aims to review this literature to collate, gauge and critically discuss understandings of the relationship between RPTs and risk, with a particular focus on audit risk. Design/methodology/approach The paper discusses RPTs and how they have been associated with corporate scandals and the expropriation of shareholders’ wealth. RPTs are defined as per accounting standards and the main types of RPTs are described based on the extant literature. Two key research design issues are discussed: measures used to operationalize RPTs and observable variations in sample size across RPT studies. Evidence is presented on the negative effects of RPTs and the role of regulation, corporate governance and auditing in reducing risks. Findings Prior studies have associated RPTs with the expropriation of shareholders’ wealth, declining firm valuations, lower-quality financial reporting, increased risk of material misstatements and decreases in long-term firm performance. Further, the evidence suggests that regulation, corporate governance and auditing can mitigate the negative effects of RPTs. Practical implications This paper provides insights for regulators on the effects of enforcement, corporate governance and external audits on reducing the negative effects of RPTs, and highlights the increased risk of material misstatements in financial statements when RPTs are conducted. Moreover, it reveals how RPTs affect risk assessments for auditors. Originality/value This paper represents the first comprehensive review of the empirical RPT literature. It provides a starting point for future investigations of RPTs, not least because it reveals important limitations with the extant body of research in this domain. It also offers salient insights and implications for practitioners and policy makers.
