What Is Treaties?

Treaty reinsurance is an arrangement where an insurer transfers an agreed portion of its risks to a reinsurer under defined terms, helping manage exposures, enhance underwriting capacity and achieve stability.
If an insurer experiences a covered loss within its treaty portfolio, the reinsurer responds according to the agreed treaty structure, retention, and limits, subject to the treaty terms and conditions.
