<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>🤝 &#039;&#039;&#039;Loss sharing&#039;&#039;&#039; is a contractual arrangement in which two or more parties — typically [[Definition:Insurance carrier | insurers]], [[Definition:Reinsurer | reinsurers]], or participants in a [[Definition:Risk pool | risk pool]] — agree to divide the financial burden of covered losses according to a predetermined formula or ratio. Rather than one entity absorbing an entire claim, loss sharing distributes the impact across multiple balance sheets, which is a foundational mechanism in structures like [[Definition:Coinsurance | coinsurance]], [[Definition:Quota share reinsurance | quota share treaties]], and government-backed [[Definition:Residual market | residual market]] programs. The concept also appears in [[Definition:Public-private partnership | public-private partnerships]] designed to cover catastrophic or otherwise hard-to-insure exposures.<br /> <br /> ⚙️ The mechanics depend on the specific agreement in place. In a [[Definition:Quota share reinsurance | quota share]] arrangement, for example, the [[Definition:Cedent | cedent]] and reinsurer split every loss by a fixed percentage — if the split is 60/40, the cedent retains 60% of each loss while the reinsurer pays the remaining 40%. In [[Definition:Risk pool | pooling]] structures common to [[Definition:Workers&#039; compensation insurance | workers&#039; compensation]] or [[Definition:Automobile insurance | auto insurance]] residual markets, participating carriers share aggregate losses in proportion to their market share or written [[Definition:Premium | premium]]. The allocation formula, caps, and floors are typically codified in the governing [[Definition:Reinsurance treaty | treaty]], pooling agreement, or enabling regulation, leaving little room for ambiguity when claims arise.<br /> <br /> 💡 Spreading losses across multiple participants makes it possible to underwrite risks that would be too volatile or too large for any single carrier to accept alone. This is especially critical for [[Definition:Catastrophe risk | catastrophe risk]], [[Definition:Terrorism risk insurance | terrorism risk]], and emerging exposures like [[Definition:Cyber insurance | cyber]], where loss experience is thin and potential severity is high. Loss sharing also stabilizes individual carriers&#039; [[Definition:Loss ratio | loss ratios]] from year to year, which in turn supports more predictable [[Definition:Pricing | pricing]] and strengthens overall market capacity.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Coinsurance]]<br /> * [[Definition:Quota share reinsurance]]<br /> * [[Definition:Risk pool]]<br /> * [[Definition:Reinsurance treaty]]<br /> * [[Definition:Residual market]]<br /> * [[Definition:Catastrophe risk]]<br /> {{Div col end}}</div>
