🚧 '''Loss corridor''' is a risk-sharing mechanism within a [[Definition:Reinsurance | reinsurance]] or [[Definition:Insurance program | insurance program]] that carves out a band of losses — between a lower and upper threshold — and assigns responsibility for that band to a specific party, typically the [[Definition:Cedent | cedent]]. It functions like a gap within a layered program: below the corridor, one set of coverage terms applies; above it, another layer of [[Definition:Reinsurance | reinsurance]] or risk transfer takes over; but within the corridor itself, the designated party absorbs the losses without external support. Loss corridors are most commonly encountered in [[Definition:Excess of loss reinsurance | excess-of-loss]] treaties, [[Definition:Stop-loss reinsurance | stop-loss]] arrangements, and health insurance risk-sharing structures.

⚙️ Consider a simplified example: a cedent purchases an [[Definition:Aggregate excess of loss reinsurance | aggregate excess-of-loss]] treaty that responds once total annual losses exceed 70% of earned [[Definition:Premium | premium]], but includes a loss corridor requiring the cedent to retain all losses between 70% and 80% of premium before reinsurance cover resumes above 80%. The corridor ensures the cedent retains meaningful skin in the game within a defined range, which aligns incentives and can reduce [[Definition:Reinsurance premium | reinsurance pricing]]. In U.S. [[Definition:Health insurance | health insurance]], the Affordable Care Act's now-expired risk corridor program operated on a similar principle, requiring insurers to absorb a middle band of gains or losses before federal sharing kicked in.

💡 From a program-design perspective, loss corridors offer a flexible tool for calibrating where risk sits between the insurer and its reinsurers or between an insurer and a government backstop. They encourage prudent [[Definition:Underwriting | underwriting]] and [[Definition:Claims management | claims management]] within the corridor band because the cedent knows it cannot pass those losses through. For [[Definition:Reinsurer | reinsurers]], corridors reduce exposure to attritional creep and keep the reinsured party engaged in managing outcomes. [[Definition:Actuarial science | Actuaries]] must model the corridor carefully when pricing a program, as the probability distribution of aggregate losses within the band directly affects both the cedent's expected retention and the reinsurer's attachment economics.
