Mediating effects of accounting conservatism on the relationship between corporate governance and cost of capital
Abstract:
The objectives of this research were to examine the direct effect of corporate governance and accounting conservatism on cost of capital, the direct effect of corporate governance on accounting conservatism, and the indirect effect of corporate governance on cost of capital through accounting conservatism. The corporate governance used in this research was based on the Corporate Governance Code for Listed Companies 2017, specifically Principle 3: strengthen board effectiveness: board size, board independence,
non-board duality, board expertise, board meeting, board attendance, and board compensation; Principle 4: ensure effective chief executive officer (CEO) and people management: CEO compensation, director ownership, CEO ownership, and family ownership; and Principle 6: strengthen effectiveness risk management and internal control: audit committee size and audit committee with financial expertise.
The population used in this study were 789 companies listed on the Stock Exchange of Thailand from 2018 to 2019, excluding companies in the financial industry group, property fund & real estate investment trust sector, and companies in rehabilitation. In total, 906 firm-year observations with complete data were collected. The statistical methods used to analyze the data were five-year rolling regression to calculate
the level of accounting conservatism along with multiple linear regression to test the direct and the indirect effects of accounting conservatism on the relationship between corporate governance and cost of capital.
The study results revealed that board expertise, board attendance, board compensation, and CEO compensation reduced the company cost of capital. Board expertise, board meeting, board attendance, board compensation, CEO compensation, family ownership, and audit committee size increased the company accounting conservatism. Accounting conservatism had a negative influence on the company cost of capital. Moreover, it was found that accounting conservatism partially mediated the influence of board expertise, board compensation and CEO compensation on cost of capital. However, accounting conservatism fully mediated the influence of board attendance on cost of capital.
