CFA Institute Updated Sustainable-Investing Exam Questions and Answers by ignacy

The single-tier board system (Option B) is the most common governance structure globally, particularly in the United States, the United Kingdom, and many Commonwealth countries. In this system, executive and non-executive directors sit on the same board, overseeing management and strategic decisions.

Joint auditors (Option A) are primarily used in France and India for financial oversight but are not a standard governance structure.

Cumulative voting (Option C), which allows minority shareholders to have a greater voice in board elections, is common in some jurisdictions (e.g., the U.S. for shareholder rights protection) but is not a universal governance structure.

France is the only major economy that mandates joint audits for public interest entities (PIEs), requiring two independent auditing firms to perform the audit.

Why France?

The French Commercial Code (Article L. 823-1) enforces mandatory joint audits to enhance audit quality and reduce financial risks.

Why not Germany or the UK?

Germany and the UK do not require joint audits.

While the UK considered joint audits, they remain voluntary rather than mandatory.

The Semite, Bhagwat, and Yankee (2018) study found that board diversity, particularly in thought and experience, helps reduce stock return volatility by:

Enhancing risk management through better decision-making.

Reducing governance failures by avoiding groupthink.

Encouraging long-term investment strategies that contribute to stable financial performance.

Why not A or C?

A is incorrect because diverse boards do not necessarily reduce R&D investment; in fact, some studies suggest they may promote more innovative decision-making.

C is incorrect because greater homogeneity (lack of diversity) often leads to poor governance outcomes, not higher profitability.

Different ESG rating agencies (MSCI, Sustainalytics, Refinitiv, etc.) use different methodologies, leading to low correlation among ratings.

Why C (more difficult for companies) is correct:

Companies struggle to improve ESG scores because rating criteria differ significantly across providers.

Example: A company may score high on MSCI but low on Sustainalytics, making it harder to demonstrate ESG improvement.

Why not A or B?

A is incorrect because inconsistency creates challenges rather than making improvement easier.

B is incorrect because ESG ratings do influence corporate ambition to improve sustainability efforts.
