Governance Scoring Methodology

How we evaluate corporate governance across European listed companies

Overview

BoardRoom's governance score is a composite metric (0 to 100) that evaluates the quality of a company's board structure and governance practices. It is computed from publicly available data, no subjective assessments or surveys.

Scoring Components

1. Board Independence (up to 25 points)

Measures the proportion of non-executive or supervisory directors on the board. Target: 50%+ independent. Companies with higher independence ratios score higher. This reflects the principle that boards need sufficient independent oversight.

2. Gender Diversity (up to 20 points)

Measures the proportion of women on the board. Target: 40%+ (aligned with the EU directive on gender balance). Scoring is linear up to the target.

3. Committee Coverage (up to 20 points)

Assesses whether the company has the four key board committees: Audit, Compensation, Nomination, and Risk. Each committee present contributes 5 points. Well-structured committees indicate proper governance infrastructure.

4. CEO/Chair Separation (15 points)

A binary measure: does the company separate the roles of CEO and Board Chairman? Combining these roles concentrates power and reduces oversight effectiveness. Companies with separate CEO and Chair receive 15 points.

5. Board Tenure (up to 10 points)

Evaluates average director tenure. The sweet spot is 2 to 10 years: enough experience for effectiveness, but not so long that independence is compromised. Tenures outside this range receive fewer points.

6. Board Size (up to 10 points)

Boards of 5 to 15 members receive full points. Too small limits diversity of thought; too large creates coordination problems and diffusion of responsibility.

Score Interpretation

Limitations

• The score reflects board structure only; it does not assess board effectiveness, meeting attendance, or decision quality
• Committee data depends on disclosure quality, which varies by country and company
• The score is backward-looking, based on the most recent annual report data
• Two-tier board systems (Germany, Poland) and unitary board systems (UK, France) are scored using the same framework, which may not fully capture structural differences

Updates

Governance scores are recomputed whenever new board position data is imported. The methodology may evolve as we expand coverage and incorporate additional governance indicators (e.g., ESG committee presence, director skills matrix, remuneration policy design).
