The document discusses the duty of utmost good faith in reinsurance contracts. It states that this duty requires high levels of honesty and disclosure between the ceding insurer and reinsurer. The ceding insurer must disclose all material facts to the reinsurer during contract formation and ongoing administration of the contract. The duty is mutual, so the reinsurer must also deal fairly with the ceding insurer. While some see it as a fiduciary duty, most courts treat it as a very high standard of good faith just below fiduciary duty. The requirements of the duty may be higher for treaty reinsurance, where the reinsurer relies more heavily on the ceding insurer.
