Research Objectives and Focus

This thesis aims to close the research gap regarding the determinants of assurance decisions in Integrated Reporting (IR), focusing specifically on the South African context, the only country to enforce a mandatory IR disclosure regime. The study investigates why firms decide to adopt IR assurance, what factors influence the selection of a particular type of assurer, and what determines the level of assurance mandated.

• Determinants of voluntary IR assurance adoption.
• Influence of corporate governance (board and shareholder characteristics) on assurance.
• Impact of industry-level and financial variables on assurance decisions.
• Role of mandatory IR disclosure in the South African setting.
• Practical insights for IR constituents (companies, providers, and regulators).

Excerpt from the Book

Summary of Chapters

1. Introduction: This chapter highlights the limitation of short-term profit paradigms and introduces Integrated Reporting (IR) as an innovation, while noting the research gap in IR assurance within the South African mandatory context.

2. Introduction to Integrated Reporting and Assurance: This chapter defines the IR concept, outlines the history of non-financial reporting, discusses advantages and disadvantages, and describes current IR assurance practices.

3. Literature Review and Hypotheses Development: This chapter reviews previous studies on voluntary assurance and develops hypotheses concerning the influence of board and shareholder characteristics on IR assurance decisions.

4. Methodology and Data: This chapter details the data collection from JSE-listed companies and explains the use of a Multiple Imputation Model to address missing data across 834 firm-year observations.

5. Results: This chapter presents descriptive statistics and multivariate logit regression results, analyzing the determinants for adopting assurance, choosing specific assurers, and mandating higher assurance levels.

6. Conclusion and Discussion: This chapter synthesizes the main findings, discusses implications for key stakeholders (companies, providers, regulators), and suggests future research avenues, including qualitative studies.

Frequently Asked Questions

What is the primary focus of this thesis?

The thesis investigates the determinants of integrated reporting (IR) assurance, specifically why companies choose to adopt it, how they select their assurance provider, and why some mandate higher levels of assurance than others.

What makes the South African context unique for this research?

South Africa is the first and only country to enforce a mandatory IR disclosure regime globally, making it a unique natural experiment for observing corporate behavior regarding IR and assurance.

What is the central research question?

The research is driven by three questions: What determines the decision to adopt IR assurance? What factors influence the choice of a specific type of assurer? And what determines the decision to choose higher levels of assurance?

Which scientific methods are employed in this study?

The study uses logit analysis on a panel of 139 JSE-listed companies observed over six years. To handle missing data, a Multiple Imputation Model (Amelia II) is employed to maintain dataset validity.

What does the main body of the work cover?

The main body covers the theoretical foundations via a literature review, the development of hypotheses based on corporate governance and shareholder structure, detailed methodology, and the analysis of multivariate regression results.

Which key variables characterize this research?

The key variables include corporate governance indicators (board size, board meetings, independence, diversity), shareholder characteristics (free-float, institutional ownership, foreign investment), and firm-level variables (industry, size, profitability, leverage).

How does board composition affect the decision to assure integrated reports?

The results show that companies with a higher number of board members and more frequent board meetings are more likely to adopt assurance, suggesting that larger and more active boards prioritize credibility and control.

Why did the author conclude that results often contradicted hypotheses?

The author found that variables such as the percentage of female board members or chartered accountants had negative associations with certain assurance choices, which was unexpected and suggests that these groups might have different perceptions or preferences regarding IR assurance than initially hypothesized.
