The Corporate Opportunity Doctrine in California: When a Director or Officer May Not Take a Business Opportunity for Themselves

How the line-of-business, interest-or-expectancy, and fairness tests decide whether an opportunity belonged to the company, and what shareholders can recover

When a director or officer of a California corporation learns of a promising deal — a property for sale, a supplier contract, an acquisition target, a new line of business — the law does not always let that insider grab it personally. The corporate opportunity doctrine is the rule that decides when

The duty behind the doctrine

Directors and officers of a California corporation are fiduciaries. They owe the corporation and its shareholders a duty of loyalty and a duty to act in good faith and in the best interests of the company. The corporate opportunity doctrine is a specific application of the duty of loyalty: it prohibits a person who occupies a fiduciary relationship to a corporation from seizing for personal benefit an opportunity in which the corporation has an interest or a tangible expectancy, or that is otherwise properly regarded as belonging to the corporation. The reason is straightforward — a fiduciary who learns of an opportunity by virtue of a corporate position, or who exploits corporate resources or relationships to pursue it, cannot ethically divert the benefit to themselves at the company's expense.

Kelegian v. Mgrdichian and the three tests

The leading California appellate discussion is Kelegian v. Mgrdichian (1995) 33 Cal.App.4th 982. The court explained that the doctrine "prohibits one who occupies a fiduciary relationship to a corporation from acquiring, in opposition to the corporation, property in which the corporation has an interest or tangible expectancy or which is essential to its existence." Whether an opportunity belongs to the corporation, the court emphasized, is "largely a question of fact" judged on the objective circumstances at the time the opportunity arose. Kelegian recognized three analytical tests that courts use, often in combination:

The line-of-business test. An opportunity belongs to the corporation when the activity is reasonably incident to the corporation's present or prospective business and is one in which the corporation has the capacity to engage. The closer the opportunity is to what the company actually does, the more likely it is corporate.
The interest-or-expectancy test. An opportunity belongs to the corporation when the company already has a legal or equitable interest or a tangible expectancy in it — what the courts describe as a "beachhead," an existing right or relationship from which the opportunity grows. A bare hope is not enough; there must be an actual interest or expectancy.
The fairness test. Courts also ask, under standards of fairness and good conscience, whether allowing the fiduciary to take the opportunity would be inconsistent with the fiduciary's duty to the corporation, considering how the fiduciary learned of the opportunity and whether corporate resources or information were used.

Under any of these tests, the court also weighs practical factors: whether the fiduciary's acquisition would hinder the corporation's plans, and whether the corporation had the financial ability and resources to pursue the opportunity itself.

What Kelegian actually decided

The specific question in Kelegian was whether a director's personal purchase of another shareholder's stock in the same corporation usurped a corporate opportunity. The court found no usurpation, because the corporation had no established policy of repurchasing its own shares and took no formal action to acquire the stock. Several directors had expressed interest, but the company had no legal or equitable interest or expectancy in those particular shares — no "beachhead" — so there was no corporate opportunity to usurp. The decision illustrates the doctrine's limits as much as its reach: not every opportunity a director pursues belongs to the company, and the plaintiff must show the company's actual interest or expectancy in the specific opportunity.

Interested-director transactions and Corporations Code § 310

The corporate opportunity doctrine operates alongside the statutory rules on self-dealing. Corporations Code section 310 governs contracts and transactions in which a director has a material financial interest. Such a transaction is not automatically void or voidable if the director's interest is fully disclosed and the transaction is approved by disinterested directors or shareholders, or if the transaction is just and reasonable to the corporation at the time it is authorized. The parallel is important: a director who wants to pursue an opportunity that might belong to the company can protect the transaction by disclosing it fully to the board and obtaining informed, disinterested approval — in effect, giving the corporation the chance to accept or decline the opportunity. A director who takes the opportunity silently forfeits that protection and invites a usurpation claim.

Presenting the opportunity to the board

The safest course for a fiduciary who learns of an opportunity that is arguably corporate is to present it to the corporation first. If the board, acting through disinterested directors with full information, declines the opportunity, the fiduciary is generally free to pursue it personally. This "presentation and refusal" step does two things: it honors the duty of loyalty by giving the corporation the first right, and it creates a record that defeats a later claim that the fiduciary secretly diverted a corporate opportunity. Conversely, a fiduciary who never presents the opportunity, and who relies on an after-the-fact argument that the company could not have afforded it or would not have wanted it, bears the burden of persuading a court on a fact-intensive record — a far weaker position.

Remedies for usurpation

When a director or officer does usurp a corporate opportunity, the remedies run to the corporation. Because the wrong is a breach of the duty of loyalty, courts can impose a constructive trust on the opportunity and its proceeds, requiring the faithless fiduciary to hold the diverted asset and profits for the benefit of the corporation. The corporation may also recover damages for the loss, and the fiduciary may be required to disgorge profits earned from the opportunity. These remedies are equitable and flexible, and they are designed to strip the fiduciary of the gain obtained through disloyalty rather than merely to compensate a market loss. Because the measure is the fiduciary's gain, a usurpation that turns out to be highly profitable produces a correspondingly large recovery for the corporation, and the faithless fiduciary does not get to keep the upside of the diverted venture. In an appropriate case, the breach may also support punitive damages and the recovery of attorney fees where a statutory or contractual basis exists. Because the claim belongs to the corporation, it is typically pursued as a derivative action by a shareholder on the corporation's behalf when the board will not act.

Who can enforce the doctrine

A corporate opportunity claim is a corporate asset, so it is ordinarily brought derivatively — a shareholder sues on behalf of the corporation after making a demand on the board or showing that demand would be futile. In closely held California corporations, where the faithless fiduciary often controls the board, the derivative route is the practical mechanism for a minority shareholder to hold an insider accountable, and demand on a board the wrongdoer controls will frequently be excused as futile. Minority shareholders in close corporations may also have direct claims grounded in the heightened fiduciary duties that controlling shareholders and directors owe to minority holders. The procedural path matters: a claim framed incorrectly as direct when it is really derivative, or brought without satisfying demand requirements, can be dismissed regardless of the merits of the loyalty breach.

The doctrine in close corporations and LLCs

The corporate opportunity doctrine has its sharpest edge in closely held businesses, where the same people are directors, officers, and shareholders, and where the line between the company's business and an insider's personal dealings is easy to blur. In a close corporation, courts recognize heightened fiduciary duties among the participants, and a controlling shareholder or managing director who diverts an opportunity harms identifiable co-owners rather than a diffuse public shareholder base. The analysis is the same — line of business, interest or expectancy, fairness — but the stakes and the scrutiny are often greater because the aggrieved minority has nowhere else to turn.

California limited liability companies raise a parallel issue. Members and managers of an LLC owe statutory fiduciary duties under the Revised Uniform Limited Liability Company Act, including a duty of loyalty that specifically encompasses not usurping an LLC's opportunity. An operating agreement can, within limits, define or narrow what counts as a competing opportunity and can authorize members to pursue outside ventures, which is why well-drafted LLC agreements frequently address outside activities and opportunity waivers expressly. In the absence of such a provision, the default loyalty duty applies, and a manager who takes an LLC's opportunity faces the same disgorgement and constructive-trust exposure as a corporate director.

Defenses a fiduciary can raise

A director or officer accused of usurping a corporate opportunity has several recognized defenses, each tied to the elements of the doctrine:

No corporate interest or expectancy. As in Kelegian, the fiduciary can show the company had no legal or equitable interest or tangible expectancy in the specific opportunity — no "beachhead" — so there was nothing to usurp.
Outside the line of business. The opportunity was not reasonably incident to the corporation's present or prospective business, so it did not belong to the company.
Presentation and rejection. The fiduciary disclosed the opportunity to a disinterested, fully informed board or the shareholders, and the company declined it, clearing the way to pursue it personally.
Inability to take the opportunity. The corporation lacked the financial capacity or legal ability to pursue the opportunity, a factor courts weigh, though it is not always a complete defense on its own.
Ratification. Disinterested directors or shareholders, with full information, approved the transaction, bringing it within the protection of the interested-director rules.

The common thread is disclosure. Nearly every strong defense traces back to the fiduciary having been transparent with the company at the time, which is why the law rewards presentation and punishes concealment. A fiduciary who kept the opportunity quiet and now argues after the fact that the company would not have wanted it, or could not have afforded it, is asking the court to accept a self-serving reconstruction of what the board would have done — a much harder sell than pointing to a contemporaneous board minute reflecting an informed decision to pass. The lesson for anyone sitting on both sides of the table, as insiders in closely held companies often do, is that the time to protect an outside venture is before it is pursued, through disclosure and a recorded decision, not afterward through litigation testimony.

Common fact patterns

The diverted contract. An officer who learns of a customer or supplier contract through the company and signs it personally or through a side entity.
The adjacent venture. A director who starts a competing or closely related business using knowledge, relationships, or resources gained at the company.
The acquisition target. A fiduciary who buys, for personal account, property or a business the corporation was pursuing or had a tangible expectancy in.
The declined opportunity. A fiduciary who properly presents an opportunity, has it declined by a disinterested board, and then pursues it — generally permissible when the presentation and refusal are genuine and informed.

Timing, laches, and the statute of limitations

A corporate opportunity claim does not stay available forever. Because it sounds in breach of fiduciary duty, it is subject to a limitations period, and California courts also apply the equitable defense of laches to constructive-trust and other equitable claims when a plaintiff delays unreasonably to a defendant's prejudice. The limitations clock is often affected by the discovery rule — the period may not begin until the corporation or the complaining shareholder knew or reasonably should have known of the diversion — which matters because a faithless fiduciary who controls the board may conceal the facts for years. Still, a shareholder who suspects an insider has taken a company opportunity should act promptly: delay can forfeit the claim, and the passage of time makes the fact-intensive proof the doctrine requires harder to assemble. The interplay of the discovery rule and laches is itself frequently litigated in these cases, so the timing analysis should be done early rather than assumed.

Practical guidance

When in doubt, present the opportunity to the board and document the decision; a genuine, informed refusal by disinterested directors is strong protection.
Do not use corporate information, relationships, or resources to pursue a personal venture without disclosure.
For boards, treat section 310 disclosure and disinterested approval as the mechanism for clearing a director's outside interest.
For minority shareholders, recognize that a usurpation claim is usually derivative and subject to demand requirements, and preserve the record of how the fiduciary learned of and pursued the opportunity.
Remember that the analysis is fact-intensive and judged as of the time the opportunity arose, so contemporaneous documentation matters.

Frequently asked questions

What is the corporate opportunity doctrine?

It is a rule derived from the duty of loyalty that prohibits a director or officer from taking for personal benefit a business opportunity in which the corporation has an interest or expectancy or that falls within its line of business.

What tests does California use?

Kelegian v. Mgrdichian (1995) 33 Cal.App.4th 982 recognizes the line-of-business test, the interest-or-expectancy ("beachhead") test, and a fairness test, applied on the objective facts at the time the opportunity arose.

Can a director ever take an opportunity related to the business?

Yes, if the corporation has no interest or expectancy in it, or if the director presents it to the board and a disinterested, fully informed board declines it.

What did Kelegian decide?

That a director's personal purchase of another shareholder's stock was not a usurped opportunity, because the corporation had no policy to repurchase shares and no legal or equitable expectancy in them.

How does Corporations Code section 310 fit in?

Section 310 lets an interested-director transaction stand if the interest is disclosed and disinterested directors or shareholders approve it, or if it is just and reasonable to the corporation — the mechanism for clearing a fiduciary's outside interest.

What can the corporation recover?

Equitable remedies including a constructive trust over the opportunity and its proceeds, disgorgement of profits, and damages for the breach of the duty of loyalty.

Who brings the claim?

Usually a shareholder suing derivatively on the corporation's behalf, subject to demand requirements, because the claim is a corporate asset; minority holders in close corporations may also have direct claims.

Does it matter whether the company could afford the opportunity?

Yes. Courts consider whether the corporation had the financial ability and resources to pursue the opportunity and whether the fiduciary's acquisition would hinder the corporation's plans.
