Building a US Board: What UK Companies Need to Know About Corporate Governance

The Fiduciary Duties of a US Board of Directors

For UK companies establishing a presence in the United States, forming a local board of directors is a fundamental step that carries significant legal and strategic implications. While the concept of a board is universal, the specific duties and liabilities of directors in the US differ in important ways from those in the UK. In the United States, corporate governance is primarily a matter of state law, with Delaware being the most common and influential jurisdiction for corporate formation. Under Delaware law, and generally across the US, directors owe two primary fiduciary duties to the corporation and its shareholders: the duty of care and the duty of loyalty. The duty of care requires directors to make informed, deliberate decisions based on all material information reasonably available to them. This means actively participating in board meetings, reviewing corporate documents, and asking critical questions of management. The duty of loyalty, on the other hand, demands that directors act in the best interests of the corporation and its shareholders, rather than their own personal interests. This prohibits self-dealing, usurping corporate opportunities, and acting with a conflict of interest. Unlike the UK Companies Act 2006, which codifies directors’ duties, US fiduciary duties are largely developed through case law, making them more nuanced and subject to interpretation by the courts. This complexity underscores the importance of having experienced counsel guide the board’s actions, a role often filled by anOutside General Counsel.

The Business Judgment Rule and Director Liability

A critical concept for any UK director serving on a US board to understand is the “business judgment rule.” This is a powerful legal presumption that, in making a business decision, the directors of a corporation acted on an informed basis, in good faith, and in the honest belief that the action taken was in the best interests of the company. When the business judgment rule applies, US courts will generally not second-guess the decisions of the board, even if those decisions ultimately turn out to be wrong or result in a financial loss for the company. This rule provides a significant shield against personal liability for directors, allowing them to take calculated risks without the constant fear of being sued by shareholders. However, the protection of the business judgment rule is not absolute. It can be rebutted if a plaintiff can show that the directors breached their duty of care by acting with gross negligence (e.g., failing to inform themselves) or breached their duty of loyalty by acting with a conflict of interest or in bad faith. If the rule is rebutted, the burden shifts to the directors to prove the “entire fairness” of the transaction, which is a much higher and more difficult standard to meet. Understanding how to secure and maintain the protection of the business judgment rule is a cornerstone of effective US corporate governance, a topic further explored in our article onCorporate Governance in a Cross-Border World.

Structuring the Board and Managing Conflicts of Interest

The composition and structure of a US board are crucial for effective oversight and compliance. A typical US board consists of a mix of “inside” directors, who are also executives or employees of the company, and “outside” or “independent” directors, who have no material relationship with the company other than their board service. Independent directors play a vital role in providing objective oversight and mitigating conflicts of interest, particularly in transactions involving the company’s founders or major shareholders. When a conflict of interest arises—for example, if a director is also an investor in a company that the corporation is considering acquiring—the director must fully disclose the conflict to the board. Under Delaware law, a transaction involving a conflict of interest can still be valid if it is approved by a majority of the disinterested directors, provided they are fully informed of the material facts. Alternatively, the transaction can be approved by a special committee of independent directors formed specifically to evaluate and negotiate the deal. Failing to properly manage conflicts of interest can expose the directors and the transaction to legal challenge and potential invalidation. Therefore, establishing clear policies and procedures for identifying and addressing conflicts is an essential part of building a robust US corporate governance framework.

The Importance of D&O Insurance and Indemnification

Given the potential for personal liability, it is standard practice in the US for corporations to provide their directors with two critical forms of protection: indemnification and Directors and Officers (D&O) liability insurance. Indemnification is a contractual agreement, typically contained in the corporation’s bylaws or a separate indemnification agreement, in which the company agrees to reimburse the directors for legal expenses, judgments, and settlements incurred in connection with their service on the board. However, indemnification is only as valuable as the company’s ability to pay. If the company becomes insolvent, the indemnification agreement may be worthless. This is where D&O insurance comes in. D&O insurance provides a crucial backstop, protecting the personal assets of the directors in the event that the company is unable or unwilling to indemnify them. It also provides coverage for the company itself when it indemnifies its directors. For UK individuals serving on a US board, securing robust D&O insurance coverage is non-negotiable. The policy must be carefully reviewed to ensure it covers the specific risks associated with the company’s industry and operations, and that it provides adequate limits of liability. By combining strong indemnification provisions with comprehensive D&O insurance, UK companies can attract and retain qualified directors for their US operations while minimizing their personal financial risk.
