Fair, competitive and profitable risk assessment Selective expertise for competitive advantage Cost-benefit analyses for requirements, processes Monitor underwriting and mortality trends to support underwriting and pricing obesity, pandemics mortality improvement new technology and medical advances Slide 4
Underwriting function interacts directly with new business and new customers Risk classification has the potential to be confusing or contentious from perspective of the applicant, agent and/or applicant s physician Underwriting performance may influence actual vs expected product experience, with narrow profit margins Medical underwriting is a complex process and not easily monitored by only quantitative models Slide 5
Enhanced accuracy of risk assessment with medical knowledge 1897 Association of Life Insurance Medical Directors of America (ALIMDA): identified association between overweight and increased mortality 1925 Joint Committee of ALIMDA and the Actuarial Society of America: 1 st Blood Pressure Study Slide 6 Mortality risks of build and BP were understood by the insurance industry long before concepts of cardiovascular risk factors were recognized in clinical medicine
1980 s: HIV awareness resulted in expanded use of laboratory testing for risk assessment Presently, multiple laboratory tests may be performed using blood, urine, and/or oral fluids to refine risk classification The search for the perfect test continues, either ahead of our time or wishful thinking Potential improvement of risk assessment accuracy with medical understanding, but not without potential conflicts in a marketing environment Slide 7
Application accuracy, extent of information Exam reliance on single measurements Identification of attending physicians or care facilities Obtaining medical information, records Interpretation of medical information Determination of mortality risk class Time and market place competition Slide 8
New lines of business The elderly market: underwriting and pricing STOLI (Stranger owned life insurance), premium financing Risk transfer: access to capital markets Fair risk selection: the right to underwrite Professional development, new underwriter training, remote underwriting Slide 9
Primary reasons for allowing remote underwriting: Slide 10 25% (28/113) companies; Swiss Re survey on remote underwriting, 2006
New medical science and technology Preferred focus Older age applicants, anticipated market expansion Monitoring and understanding mortality trends obesity and related impairments pandemics Slide 11
Emerging interdisciplinary field of research and clinical applications Focused on repair, replacement, or regeneration of cells, tissues, or organs to restore impaired function resulting from any cause, including congenital defects, disease, and trauma Combines several technological approaches beyond traditional transplantation and replacement therapies. Slide 12 Approaches may include use of stem cells, soluble molecules, genetic engineering, tissue engineering, and advanced cell therapy
Application Pancreatic islet regeneration for diabetes Regeneration of heart muscle Immune system enhancement engineered cells, vaccination Tissue engineered skin substitutes Umbilical cord blood banking for future cell replacement therapies Tissue engineered cartilage, modified chondrocytes Inherited blood disorders - gene therapy, stem cell transplants Nerve regeneration using growth factors, stems cells, synthetics Slide 13 Example Bone marrow stem cell transplant, genetically engineered cells to express insulin Myocardial patch, autologous marrow cells - repair Genetically engineered immune cells to enhance or repair immune function Intelligent dressing- skin loss with burns, wounds Future therapy for diseases: diabetes, stroke, myocardial ischemia, Parkinson s, leukemia Cartilage repair for degenerative joint disease Genetically engineered stem cells to restore normal blood cell function beta-thalassemia Spinal cord and peripheral nerve injuries

Diagnostic advances may improve ability to predict or measure specific risk with implications for risk classification brain natriuretic peptide (BNP) noninvasive coronary arteriography, CT, MRI virtual colonoscopy genetic testing Therapeutic advances targeted therapies Slide 15 endovascular techniques
Hormone first identified in brain, also produced in heart ventricles, increased in congestive heart failure, left ventricular dysfunction (+ symptoms) Uses: diagnosis, prognosis, prediction heart failure, other cardiovascular diseases/events Increased BNP associated with heart failure, atrial fibrillation, TIA & CVA risk, & increased mortality risk NT-ProBNP (stable, inactive portion) testing through insurance labs, particularly in older applicants Slide 16 Reference ranges, insurance cutoffs still to be determined
One revolution in modern science is our ability to connect particular genetic findings with occurrence of specific diseases at an ever increasing pace Only in rare cases is a gene test result near 100% predictive, best example Huntingtons Disease Some gene changes associated with disease are acquired not inborn, example most cancers Expression of most gene linked diseases depends on Interaction between individual s genome and environmental factors Slide 17 Genetic privacy concerns, legislation, GINA
Human Genome Project, sequenced all human chromosomes, 3164.7 million bases (A, C, T, & G), next step is to figure out what the 25,000+ genes do In each gene, bases sequence = instructions to make proteins, each has specific function. Many diseases result of genetic mutations which affect proteins (alter function, amount made; 0 to excess) Genes important for health, genetic component to all diseases; search for genetic variations, mutations more accessible, affordable Slide 18 Screening, diagnosis, treatment; commercial & research labs, individualized therapies, significant impact on practice of medicine

Will sources of mortality improvement continue to conceal the impact of obesity on mortality levels in the future? Could past mortality improvements have been higher if the prevalence of obesity had been stable? Can we quantify these lost mortality improvements attributable to the increasing prevalence of obesity? Slide 38
In contrast to the young, the distribution of elderly by disease burden is quite diverse. A minority have relatively few problems and represent the population most likely to have best class level mortality. As a proportion of the total group the numbers of such best class risks will be much smaller than at younger ages. # of Chronic disease prevalence by age group chronic conditions 65-69 70-74 75-79 80-84 85+ 0 25.7% 18.9% 15.2% 12.6% 12.2% 1 20.4% 18.0% 16.0% 14.9% 15.0% 2 22.2% 22.5% 21.6% 20.9% 21.0% 3 16.0% 18.7% 19.9% 20.4% 20.4% 4+ 15.7% 21.9% 27.3% 31.2% 31.4% Higher morbidity burden at older ages, applicant population with greater risk of overt or pre-symptomatic disease and premature mortality.

Swiss Re has built a pandemic influenza model that takes account of a wide range of factors present in the three pandemics of the last century Includes many of the widely-recognised interventions that may slow or mitigate the effects of a pandemic Seeks to imitate the capacities of the public and institutions to respond to a pandemic, and to maintain these responses Slide 43
Conclusions from the pandemic model after all inputs: There is roughly a 3-4% probability of a pandemic of any degree occurring in any given year Additional factors for consideration pro Global human travel and commerce Urbanization con Poor (non-existent) human-to-human H5N1 transmissibility Major improvements in surveillance and medical care Based on historical frequencies, the chances of a severe pandemic occurring appear to be relatively small, on the order of 0.3% or less Slide 44
Swiss Re has built an influenza spread model which has been calibrated against the 3 pandemics of the last century. Basic reproduction rates and lethalities have been used to parameterise statistical distributions. Values are randomly generated off these to define a pandemic. 1,000 runs have been used to produce the distribution of mortality outcomes shown here. The distributions shown here represent interventions available in 1918 and 2006. The three pandemics of the last century are shown on the output of 1,000 runs of the Swiss Re model The model indicates excess population mortality of 1.3 per thousand in a 1 in 200 year event Further allowance should be made for the lower mortality of insured populations versus general populations Organisations with globally diversified portfolios would further benefit from the time it takes for the pandemic to spread around the globe in comparison with those with a more concentrated exposure, as more effective interventions could be utilised as understanding of the virus increases with time Slide 45
Freedom to quantify, group similar risks together is fundamental in establishing equitable homogeneous risk distribution within the pool fair competitive price for consumer maintain experience in line with morbidity or mortality assumptions for the insurer full disclosure, information symmetry Challenges by regulators and governments to demonstrate that risk selection process is fair and priced on actuarially sound basis Slide 46 Travel, Genetic testing, Unisex, specific impairments
