Insurance-Linked Securities:
Catastrophe Bonds, Sidecars and Life Insurance Securitization
Last Updated: 09/03/15

Insurance-linked securities (ILS) are products of the rapid development of financial innovation and the process of convergence between the insurance industry and the capital markets. The securitization model has been employed by insurers eager to transfer risk and tap new sources of capital market funding. Insurance-linked securities—both from the life and property/casualty sectors—hold great appeal for investors.

According to Swiss Re, ILS issuance for 2014 grew to $8.29 billion across 27 transactions, reaching a new high-water mark following two years of falling short of the record $8.24 billion issued in 2007, new. The influx of first time sponsors in the first half coupled with the return of seasoned issuers has for the second year in a row pushed the size of the ILS market to record highs.

In the first half of 2015, there has been around $5 billion in volume of newly issued Cat Bonds split between more than 20 tranches placed in the market Issuance activity is expected to remain strong in the second half of the year, with the majority of Cat Bonds expected to be marketed during the fourth quarter of the year. It is expected the total issuance by year-end will be at least $7 billion for publicly offered Cat Bonds.

As of December 31, 2014 the overall outstanding ILS market had grown to $24.1 billion, approximately 20% larger than the market size at year end 2013. Driven by healthy investor demand, and in the absence of a large event, spreads were pushed down to new lows. At the same time, while new issue spreads have continued to tighten, it does appear that the market might have found its floor.

While the ILS market has grown substantially in recent years and U.S insurers are active participants as bond sponsors, their ownership of these securities is limited. The aggregate investment in ILS for the U.S. insurance industry was $168 million at year-end 2013, a substantial decrease from the $428 million the industry held as of 2011 year-end. As of year-end 2013 life insurers held $134 million in ILS, of which 76% was in cat bonds and 24% in ILS-assuming mortality and morbidity risks. Property/casualty (P/C) companies held a more modest $29 million of ILS, of which 81% was in cat bonds and 19% was in ILS-assuming mortality and morbidity risks. Investor appetite for these aforementioned risks has increased in 2014 due in part to their attractive spreads coinciding with investors’ ongoing search for higher yielding investments. Also, in 2014, the cat bond market has shown a preference for U.S. hurricane risk.

Catastrophe Bonds

Catastrophe bonds (commonly abbreviated to cat bonds) are a segment of the ILS market. They are used by property/casualty insurers and reinsurers to transfer major risks on their books (such as for hurricanes, windstorms and earthquakes) to capital market investors, reducing their overall reinsurance costs while freeing up capital to underwrite new insurance business. Cat bonds are structured so that payment of interest or principal to the reporting insurance company depends on the occurrence of a catastrophe event of a defined magnitude or, that causes an aggregate insurance loss in excess of a stipulated amount.

The risk inherent in cat bonds is a key reason these securities are of relatively short duration, typically maturing in three to five years. According to Standard & Poor’s, as of the end of 2013 only seven rated cat bonds had ever defaulted. Three of those were event-driven, and four were connected to the collapse of Lehman Brothers in 2008. In addition, both Queen Street II Capital Ltd. and Queen Street III Capital Ltd. are now on CreditWatch due to small losses from their MMF investments.

Catastrophe bonds remain a useful diversifying risk tool for investors’ portfolios and a valuable risk transfer tool for sponsoring insurance companies. As interest rates remain near historic lows investors continue to look for yield in alternative assets classes. The spreads available in the high-yield markets highlight the attraction of the ILS market which has been the beneficiary of large inflows from institutional investors. The increased investment in cat bonds have helped tightened spreads significantly over the course of 2014 as low interest rates continued to provide a favorable issuance environment.

Insurers, in addition to being issuers of these securities, can and do invest in them on a limited basis. Insurance companies purchase these securities to diversify their portfolios. Typically, insurers are not expected to invest in a cat bond if they are already exposed to the peril in question in their primary business. Insurers that do invest in cat bonds were in the past required to file them with the NAIC Capital Markets & Investment Analysis Office for determination, as they were not eligible for filing exemption under the NAIC rule which grants an exemption from filing for securities that have been assigned a current, monitored rating by an ARO (acceptable rating organization) as prescribed in the Purpose and Procedures Manual. At the 2014 NAIC Spring National Meeting, the VOS Task Force adopted a motion to make rated cat bonds filing exempt. The NAIC Capital Markets & Investment Analysis Office is also expected to recommend at the2014 NAIC Summer National Meeting to the VOS Task Force that those cat bonds that are not rated to be subject to the 5*-6* certification process as prescribed at the Purpose and Procedures Manual.

According to the 2015 Global Risks report by the World Economic Forum, extreme weather events are regarded as the second most prevalent threat to global stability in terms of likelihood, following interstate conflict with regional consequences. The cat bond market remains dominated by U.S. hurricane risk. In 2014, about 90% of the total issued cat bonds had hurricane as the sole or primary covered peril. According to Standard & Poor’s, a few of the new issuances that came to market during the past two years provided some sought-after opportunities for investors to diversify their portfolios into non-U.S. peak perils such as Japanese typhoon, Japanese earthquake, Turkish earthquake, European windstorm, Canada earthquake, Caribbean hurricane, and health claims payments.


Another structure for transferring catastrophe risk to investors is the sidecar, which became very popular in the aftermath of Hurricane Katrina. Sidecars are deployed mainly by reinsurers following major catastrophes to add risk-bearing capacity in periods of increased market stress. Sidecars are special-purpose vehicles through which reinsurers cede premiums associated with a book of business to investors who place sufficient funds in the vehicle to ensure claims are paid if they arise. In contrast with cat bonds, which are structured as long-term instruments covering a broad array of perils and geographies, sidecars are tactical instruments of limited duration during a hard market.

As severe natural catastrophes become more frequent due to changing climatic conditions, insurers and reinsurers may boost their issuance of cat bonds and sidecars as additional protection from the risk of incurring solvency-threatening losses. According to InsuranceRisk, the number of sidecars is expected to grow alongside cat bonds, as reinsurers seek to expand and capacity investors look for high-yielding assets. Sidecar market capacity is conservatively estimated at around $2 billion from a total catastrophe risk capital market capacity of approximately $42 billion.

As part of regulatory efforts to help manage catastrophe risk, the NAIC and state regulators have developed a comprehensive national plan that incorporates new risk management techniques with a solid foundation of solvency and consumer protection inherent in state insurance regulation.

Life Insurance Securitization

Life insurance securitization is also a segment of the ILS market. Mortality and longevity risk securitizations fulfill a similar function for life insurers, as catastrophe bonds and sidecars do for property/casualty insurance and reinsurance companies—the transfer of risk to the capital markets.

Extreme risks of increasing mortality rates due to natural catastrophes and pandemics could potentially present a challenge to a life insurer’s solvency. A jump in mortality rates would adversely affect the amount and timing of death benefits an insurer must pay. Longevity risk is the other side of mortality risk. A rise in longevity rates would increase cash outflows due to more annuity payments.

Apart from transferring mortality risk, life insurance companies have employed securitization techniques to: a) monetize the embedded value of a particular block of business in order to fund acquisition or demutualization costs and b) fund the extra reserves required by regulations XXX (Valuation of Life Insurance Policies Model Regulation #830). Often, a captive insurance company is at the center of Regulation XXX life securitization structures and it is used as a repository for the funds that were available from the securitization.
