Frequently Asked
3
When must a promoter disclose a self-dealing transaction to avoid liability for breach of fiduciary duty?+
A promoter must make full disclosure of any secret profit and obtain approval from all persons contemplated as part of the original financing scheme. Disclosure to only some initial subscribers is insufficient. The corporation may recover the profit or rescind the transaction if full disclosure and ratification do not occur.

What remedy is available when a third party receives property with notice that an agent breached a fiduciary duty?+
The recipient holds the property as a constructive trustee. The principal may also elect to recover the value of the property or obtain restitution to the extent of unjust enrichment.

Does a member of a member-managed LLC breach the duty of loyalty by diverting a company opportunity to a competing entity she controls?+
Yes. The duty of loyalty requires the member to account for any benefit derived from the appropriation of a company opportunity. Using company resources or personnel to develop the opportunity strengthens the claim that the benefit belongs to the LLC.
