Reinsurance sidecar

Reinsurance sidecars, conventionally referred to as "sidecars", are financial structures that are created to allow investors to take on the risk and return of a group of insurance policies (a "book of business") written by an insurer or reinsurer (henceforth re/insurer) and earn the risk and return that arises from that business. A re/insurer will only pay ("cede") the premiums associated with a book of business to such an entity if the investors place sufficient funds in the vehicle to ensure that it can meet claims if they arise. Typically, the liability of investors is limited to these funds. These structures have become quite prominent in the aftermath of Hurricane Katrina as a vehicle for re/insurers to add risk-bearing capacity, and for investors to participate in the potential profits resulting from sharp price increases in re/insurance over the four quarters following Katrina. An earlier and smaller generation of sidecars were created after 9/11 for the same purpose.

Sidecars have precedents in the reinsurance market under the name "quota-share reinsurance." In such an agreement, a re/insurer agrees to cede to the quota-share reinsurer a percentage of all premiums arising from a book of business in exchange for the reinsurer bearing the same percentage liability for losses. The quota-share reinsurer pays an amount called the "ceding commission" to compensate the ceding company for its expenses. The ceding commission typically also includes a profit allowance, which increases in proportion to the expected profitability of the business. These reinsurance treaties currently and traditionally provide ceding companies with the ability to write more business than they could bear based on their own capital and to earn a certain amount of fee-based income (through the ceding commission). Quota-share reinsurers act as insurance wholesalers, allowing them to earn a return on capital without creating primary insurance distribution. Lloyd's of London "names" act as such reinsurers, placing the resources of individual and firms at risk to books of business written by professional underwriters and agents.

Re/insurers have occasionally created joint ventures through which multiple parties place capital at the disposal of one or more expert underwriters for the same reasons. The earliest sidecars were created in Bermuda in the 1990s in such a fashion, and included Top Layer Re and OpCat, both of which placed capacity under the control of Renaissance Re on the part of other re/insurers (Overseas Partners, State Farm).
