Alternative Risk Transfer (ART) market mechanisms cover 30 percent of the U.S. commercial insurance market, yet general understanding of them is limited. For anyone grappling with the concept, an I.I.I.-penned chapter in the recently published Handbook of International Insurance hopefully will shed some light. The chapter Ã¢â‚¬Å“An Overview of the Alternative Risk Transfer MarketÃ¢â‚¬ explains that the concept of ART defies a precise definition in part because the broad range of risk products that can be defined as ART has expanded over time as product innovation continues. The chapter covers the major categories of ART solutions commonly found in the market today, including captives, self-insurance, risk retention groups, finite risk (re)insurance, catastrophe bonds and government programs. I.I.I. also has additional information on captives and other risk-financing options available online.
