Corporate Finance

I. Lesson Focus

II. The Problem

Suppose you are an outside shareholder of a listed company. You notice that management has repeatedly pursued high-premium acquisitions, over-invested in low-return projects, and the CEO’s compensation shows almost no correlation with company performance. How do you determine whether the company suffers from severe agency problems? Are the corporate governance mechanisms effective? Is the board sufficiently independent? These questions directly affect your investment decisions and the firm’s long-term value. This lesson systematically explains the corporate governance framework, major conflicts, governance mechanisms, and evaluation methods, enabling you to quickly identify governance risks in both exams and practice.

III. Basic Concepts of Corporate Governance

Corporate governance refers to the system of rules, practices, and processes by which a company is directed and controlled. Its primary objective is to reduce agency costs, protect shareholder interests, and promote sustainable long-term firm value.

The agency problem is the central driver of corporate governance. When ownership is separated from control, managers (agents) may pursue personal benefits at the expense of shareholders (principals). Common manifestations include: - Excessive perquisites - Empire building - Short-termism - Risk aversion

Stakeholder theory suggests that companies should balance the interests of creditors, employees, customers, suppliers, and society in addition to shareholders. However, CFA Level I places primary emphasis on shareholder value maximization.

IV. Major Conflicts in Corporate Governance

1. Shareholder–Manager Conflict (most important)
2. Managers may choose low-risk projects to protect their jobs
3. Managers may receive large bonuses despite poor performance

4. Managers may engage in “tunneling” to transfer corporate resources for personal gain

5. Shareholder–Creditor Conflict

6. Asset substitution: shareholders encourage managers to undertake high-risk projects; upside belongs to equity, downside borne by debt holders
7. Over-distribution of dividends

8. Creditors respond with protective covenants

9. Controlling Shareholder–Minority Shareholder Conflict (common in emerging markets)

10. Controlling shareholders expropriate minority shareholders through related-party transactions and guarantees
11. Pyramid structures and cross-holdings exacerbate the problem

V. Corporate Governance Mechanisms

(A) Internal Mechanisms

• Board of Directors
• Composition: executive, non-executive, and independent directors
• Key committees: audit, compensation (remuneration), and nominating (governance)

• Independence indicators: percentage of independent directors, separation of chair and CEO roles

• Managerial Incentive Mechanisms

• Equity-based compensation (stock options, restricted stock)
• Performance-based bonuses

• Clawback provisions

• Shareholder Rights

• Voting rights: one-share-one-vote versus dual-class shares
• Shareholder proposal rights
• Cumulative voting

(B) External Mechanisms

• Market for corporate control (hostile takeovers)
• Creditor monitoring
• Regulatory oversight and legal frameworks
• Reputation market
• Analyst and media scrutiny

VI. Corporate Governance Evaluation Metrics

CFA Level I candidates should master the following commonly used indicators: - Board independence (% of independent directors) - CEO duality (whether the chair and CEO roles are combined) - Ownership concentration - Institutional ownership percentage - Number of anti-takeover provisions - Governance pillar score within ESG ratings

Worked Cases

Case 1: Board Independence Analysis

A company has a nine-member board with four independent directors. The chairman also serves as CEO. The firm’s ROE has been below the industry average for two consecutive years, yet the CEO’s total compensation ranks in the top 10% of the industry. Evaluate the quality of governance.

Analysis: - Independent director ratio = 4/9 ≈ 44.4% (below the recommended minimum of two-thirds or 66.7%) - CEO duality exists, severely compromising board independence - Compensation is decoupled from performance, indicating a clear agency problem Conclusion: Governance mechanisms are weak; shareholders should push for board reform.

Case 2: Shareholder versus Creditor Conflict

A highly leveraged company (D/E = 2.0) faces two mutually exclusive projects: - Project A: low risk, NPV = +$0.8 million - Project B: high risk, NPV = –$0.2 million, but offers massive upside to shareholders if successful

If management is controlled by shareholders, which project is most likely to be chosen and why?

Analysis: Shareholders will choose Project B (asset substitution). Although the overall NPV is negative, the high-risk project allows shareholders to capture all upside if successful while limited liability shifts most downside losses to creditors. Creditors can mitigate this risk through restrictive covenants that prohibit such high-variance investments.

Case 3: Impact of Dual-Class Share Structure

A technology company uses a dual-class structure in which the founder holds all Class B shares (10 votes per share) while public Class A shares carry one vote per share. The founder owns only 12% of economic interest but controls 68% of voting rights. The company recently rejected an acquisition offer that was clearly value-enhancing for all shareholders.

Analysis: The dual-class structure creates a severe wedge between voting power and economic interest. The founder can control the board and reject the takeover to preserve personal control, harming minority shareholders. This is a classic controlling-shareholder versus minority-shareholder conflict. Investors should apply a governance discount in valuation.

Traps

Key Formulas

• Independent director ratio = Number of independent directors / Total board members
• Voting power concentration = Controlling shareholder’s voting rights percentage
• Agency costs ≈ Excessive perquisites + Value destruction from suboptimal investment decisions
• Economic ownership ≠ Voting control (especially pronounced under dual-class structures)
• Low correlation between ROE and CEO pay → signal of governance failure
• More anti-takeover provisions → weaker external governance

Answers

Takeaways

• Corporate governance exists primarily to solve agency problems arising from the separation of ownership and control
• Board independence (≥ two-thirds independent directors) and separation of chair and CEO are critical internal governance signals
• The three major conflicts are shareholder–manager, shareholder–creditor, and controlling–minority shareholder
• Dual-class equity structures amplify controlling versus minority shareholder conflicts
• Equity incentives must be accompanied by clawback provisions to be effective
• Companies with weak governance typically trade at a valuation discount; analysts must explicitly assess governance risk
