2 Agenda 1 Motivation of the study 2 Methodology 3 Empirical analysis 4 Interpretations of the findings Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
3 Motivation of the study The study is conducted to fulfill multiple objectives The research objectives listed below are tightly connected and not mutually exclusive: To comply with regulations Several regulations require assets to be held at fair value International Financial Reporting Standards (IFRS) 13 Alternative Investment Fund managers Directive (AIFMD) To provide guidance for life settlement bidders The two-variable model developed in the study can be used as a valuation rule of thumb. To raise the awareness of the importance of LE accuracy LE is the driver of life settlement valuation. Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
4 Motivation of the study Life expectancy is the key driver of price theoretical evidence 80-Year-Old Male Non-smoker P0 Simulated P0 IRR k-relationship k = 3.0 or LE = 7.8 k = 1.5 or LE = 10.4 k = 1.0 or LE = P0 = 0.2 P i= k, or its natural logarithm ln k, is used to indicate underwriting aggressiveness, throughout the study IRR πi Probi IRR i + P i=1 1 Probi IRR i, where TP P0 = : transaction price (TP) as a fraction of death benefit () k: implied mortality multiplier (VBT 2015) LE : life expectancy (in years) Probi : Survival probability at time i πi : premium rate (to ) at time i k up Probi down & LE down & P0 up Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
5 Agenda 1 Motivation of the study 2 Methodology 3 Empirical analysis 4 Interpretations of the findings Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
6 Methodology Dependent variables Two variables to proxy valuation: TP : Price multiplier; Transaction price TP as a fraction of death benefit - We bought the policy at 20 cents on the dollar - cash-flow-based - more direct, less comparable RP: Risk premium; internal rate of return IRR in excess of risk-free rate r - This policy was sold at 20% - return-based - less direct, more comparable Relation of the two: TP = f (RP) = C i (1 + RP + r) i, i=0 Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
7 Methodology Independent variables Log-linear best describes LE- TP relationship: T P = LE R 2 = LE Figure: Linear T P LE Figure: Log-linear = ln LE R 2 = T P = LE LE LE 3 R 2 = LE Figure: Polynomial T P = exp( LE) R 2 = LE Figure: Exponential Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
8 Risk proxies I Independent variables Variables that affect both valuation proxies: risk risk up TP down; RP up Longevity risk Stemming from inaccurate (or most likely too short) LE estimates ln LE Natural logarithm of life expectancy ln Natural logarithm of death benefit DI Difference in LE estimates MK Market NO Number of LE estimates AG Insured s age CO Premium convexity Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
9 Risk proxies II Independent variables Premium risk Pertaining to an increase in premiums of an in-force policy PM Sum of expected premiums as a fraction of death benefit Default risk Linked to the uncertainty in insurers ability to honor claims should financial distress occur RT Credit rating Rescission risk Associated with insurance carriers refusal to pay the death benefit due to a lack of insurable interest or other fraudulent behavior at issue VI Vintage Xu (I.VW-HSG) Valuation in U.S. Life Settlements / 21
