Alternative risk transfer
Alternative risk transfer (often referred to as ART) is the use of techniques other than traditional insurance and reinsurance to provide risk-bearing entities with coverage or protection. The field of alternative risk transfer grew out of a series of insurance capacity crises in the 1970s through 1990s that drove purchasers of traditional coverage to seek more robust ways to buy protection.
