Hedging Longevity Risk with Longevity Bonds: Modeling, Design, and Valuation

Advances in Economics, Management and Political Sciences
The increasing life expectancy of humans poses significant longevity risk to life insurance companies and pension providers. This paper provides a systematic review of longevity bonds as a financial instrument for hedging longevity risk, examines stochastic mortality models, with a focus on the Lee-Carter model, and discusses the classification ...

Hedging longevity risk by issuing mortality bonds

2014
With the advances in pharmaceutical industry, and the improvement of living standards, life expectancy has risen steadily since the 1960’s in the Europe and North America. Also significant underestimation of the longevity improvements and high uncertainty about future mortality has made longevity a high-profile risk for pension funds, insurers, and ...

Effects of Grape Seed Extract-Modified Etchants on Collagenolytic Activity, Interface Formation, and Bonding Longevity of Adhesive–Dentin Interfaces

Materials
This study investigated the effects of acid etching with grape seed extract (GSE)-modified etchants, varying phosphoric acid (PA) concentrations, on endogenous collagenolytic activity of etched dentin, adhesive–dentin (A/D) interfacial formation, and ...

In Vitro Longevity of Bonding Properties of Universal Adhesives to Dentin

Operative Dentistry, 2015
SUMMARY Purpose To evaluate the immediate and 6-month resin-dentin bond strength (μTBS) and nanoleakage (NL) of universal adhesives that contain or do not contain methacryloyloxydecyl dihydrogen phosphate (MDP) and are used in the etch-and-rinse and self-etch strategies.

Chlorhexidine-containing Acid Conditioner Preserves the Longevity of Resin-dentin Bonds

Operative Dentistry, 2009
SUMMARY The current study evaluated the effect of 2% chlorhexidine digluconate (CHX) on the immediate and six-month resin-dentin bond strength (BS) and nanoleakage pattern (NL) of etch-and-rinse adhesives when applied in aqueous or associated to the phosphoric acid conditioner.

Effect of combining different 10-MDP-containing primers and cement systems on shear bond strength between resin cement and zirconia

BMC Oral Health
The longevity of zirconia restoration depends upon its esthetic, proper occlusion, marginal adaptation, and restoration retention. This study aimed to investigate the combination of 10-MDP-containing primers between the two commercial systems (Scotchbond

Effect of the smear layer created by diamond bur grinding on the long-term bond strength of universal adhesive systems to dentin

The journal of adhesion
The smear layer interferes with dentin permeability by decreasing the surface energy of the tooth structure. This can influence the longevity of bond strength to dentin, especially when self-etching or universal adhesive systems are used, depending on ...

Living with Mortality: Longevity Bonds and Other Mortality-Linked Securities

British Actuarial Journal, 2006
ABSTRACTThis paper addresses the problem of longevity risk — the risk of uncertain aggregate mortality — and discusses the ways in which life assurers, annuity providers and pension plans can manage their exposure to this risk. In particular, it focuses on how they can use mortality-linked securities and over-the-counter contracts — some existing and ...
