Derivative Lawsuits: The Role of D&O Insurance

In the realm of corporate governance and professional liability insurance, few exposures are as complex as the derivative lawsuit. Unlike a direct lawsuit—where a shareholder sues for a personal injury to their own interests (such as a failure to disclose financial information)—a derivative action is brought by a shareholder on behalf of the corporation.

The logic behind a derivative suit is that the corporation has a valid legal claim against its own directors or officers, but the leadership is unwilling to pursue it because they would essentially be suing themselves. Consequently, the shareholder "steps into the shoes" of the company to seek redress for harm done to the entity. Because the recovery in these cases goes back into the corporate treasury rather than to the individual shareholder (minus legal fees), these suits present unique challenges for Directors and Officers (D&O) insurance policies.

D&O insurance is typically structured into three primary "sides" or insuring agreements. Understanding these is vital for anyone preparing for practice Professional Liability questions. The interaction between these sides and derivative suits is a frequent exam focus.

• Side A (Individual Coverage): Protects directors and officers when the corporation is legally unable or financially incapable of indemnifying them.
• Side B (Corporate Reimbursement): Reimburses the corporation for the costs it pays to indemnify its leaders.
• Side C (Entity Coverage): Protects the corporation itself (usually limited to securities claims in public company policies).

Derivative suits are particularly dangerous for directors because, in many jurisdictions, a corporation is prohibited by law from indemnifying its directors for a settlement or judgment in a derivative action. The theory is that the company cannot pay for a loss that it is technically "receiving" as the plaintiff. This creates a gap where the director has personal liability that the company cannot fill, making Side A coverage the essential safety net for the individual's personal assets.

A standard exclusion in many D&O policies is the Insured vs. Insured (IvI) exclusion. This is designed to prevent the policy from being used as a "corporate checkbook" where the company sues its own managers to recover business losses. However, because a derivative suit is technically the company suing its own people, there was historically a risk that this exclusion would bar coverage for legitimate shareholder actions.

Modern policies address this by including a specific carve-back for shareholder derivative actions. As long as the shareholder is acting independently of the board and management, the IvI exclusion generally does not apply. This ensures that the defense costs and potential settlements are covered, provided the shareholder was not assisted or instigated by an insured person.

Before a shareholder can proceed with a derivative suit, they must usually satisfy the demand requirement. This involves asking the Board of Directors to bring the suit themselves. If the Board refuses, the shareholder must prove that the refusal was not a valid exercise of business judgment.

Companies often form a Special Litigation Committee (SLC) of independent directors to evaluate these demands. The costs associated with an SLC investigation are a significant exposure. While some D&O policies provide a specific sub-limit for SLC investigation costs, many basic policies may not consider these to be "Defense Costs" because no formal claim has been made against an individual yet. Professionals must carefully review the definition of a "Claim" in the policy to ensure these investigative expenses are covered.
