The impact of board capital on total value reporting: evidence from the Australian health care sector

Purpose This study investigates the association between board gender diversity and multiple directorships, two board characteristics representing human, social and relational capital and the extent to which corporate reporting (using the double materiality principle) explains value creation for the organization, environment, society and the economy, which we define as total value reporting. Design/methodology/approach This study uses a disclosure index developed based on the Integrated Reporting Framework and the Global Reporting Initiative (G4) guidelines to analyze disclosures made using the double materiality principle and reflect the value created by companies. The sample includes corporate reports of 102 Australian Securities Exchange (ASX) companies in the Health Care sector. Ordinary least squares regression analyses test the relationship between board gender diversity and multiple directorships and the quality of total value reporting (and its subcomponents) with appropriate control variables. Findings Findings reveal that human, social and relational capital formed through multiple directorships and gender-diverse boards is positively related to the quality of total value reporting. Results hold for alternative measures and sensitivity tests of gender diversity and multiple directorships. Practical implications Our study reveals that (1) the <IR> Framework, when combined with the GRI Framework, effectively measures connected information quality under a double materiality perspective for total value reporting; (2) enhancing board effectiveness for total value reporting is achievable by increasing female directors and those with multiple directorships; (3) limitations in accessing experienced directors, particularly women, do not disadvantage countries like Australia and (4) directors holding multiple board positions are pivotal in disseminating best practices in corporate governance and reporting across various companies and industries. Social implications Our research reveals that gender diversity on corporate boards transcends mere representation, significantly enhancing how firms articulate their value to stakeholders. This finding underscores the urgency for public policies to advocate for increased female board representation. Additionally, our findings indicate that board diversity, encompassing gender, experience, industry background and cultural perspectives, can elevate transparency in reporting, crucial for attracting global investors, particularly in emerging markets. Originality/value Our study is an early attempt to examine total value reporting – underpinned by double materiality – which reports on how companies create value for themselves, the environment and society. It is one of the first to identify drivers of reporting based on double materiality.
