Themain objective of this article is to propose an improvement of our understanding of the lifeinsurance risk management system and to anticipate the evolutions of our environment whileguaranteeingoursolvencyandtherobustnessofourhypothesesinfrontofthemajorityofextremesituationsthatmayoccur.
To achieve this goal,wehave chosen to adopt theCOSO II reference framework (see section 7.3)whichfacilitatesouranalysisasawhole.Westructuredourapproachinthreemainstages:

PREAMBLE
After aperiod "2000-2010" seenas "the tenglorious" in the insurance sector, French insurers arepresented,withaviewto2020,withmoreuncertaintyinviewofthevariousscenariosthatsucceedtheinthelastfiveyears(TheimplementationofsolvencyIIandIFRS17,entryintoforceoftheANI-mutualhealthextendedtoallemployees-managementofunclaimedcontractswiththeACPRduetoEckertlaw,effectsoflawsontheresultsofinsuranceloans,FLATTAX,etc.)andotherscenariosthatmaydetermine their future.At the same time, it isnecessary tohelp thevariousdistributionnetworksinthemarketingofnewcontracts(EUROCROISSANCEtype)andtrainthesalesforcestothespecificitiesofunit-linkedcontractswiththehelpofDATASCIENCEtechniqueswhilebenefitingfromtheimpactofdigital,connectedobjects,BIGDATA.
Theseare just someof the issues that couldbedescribedasendogenous, as low interest ratesorclimate change, the rapid aging of the population, and the government's disengagement fromcoverage.social,allrelatedtotheexogenousenvironment,bringmanychallengestotheplayers intheprofession,creatingnewneedsandopportunities.
The situation is complex for insurers, who have to deal with these trend breaks, temporary oroccasional,whilethecurrentcontextisthattheyobserveadeclineinmargins.Therequirementsofmoreinformedcustomersaswellasmorestringentobligations(regulationandcompliance)requireadeepeningandbettermanagementofdriftphenomena.
The evolution of data quality, statistical techniques, the advent of BIG DATA make it possible toobtain a better knowledge of the customers (insured or partners) and create possibilities goingbeyond a better customer knowledge: these recent developments could also be used to evaluatethese trendbreaks (due to exogenousor endogenous factors) but especially to replicate them forpurposesofeconomiccapitalassessmentandbetterknowledgeofrisks.
The objective of this article is therefore to present a system of analysis, management andanticipation of the phenomena of drifting on the underwriting risks which will have to be fullyintegratedintotheORSAriskmanagementsystem,agile,coherent,framedandespeciallyrelatedtostrategies of appropriation of stress scenarios and control of solvency by the leaders of insuranceorganizations.

Ourknowledgeoftherisksaswellastheirevolutionrequirestodistinguishthevariousphenomenathatcancharacterizethem.Biometricandbehavioralrisksarecharacterizedbythecombinationoftwo(2)phenomena:trendanddrift.Wecanconsiderthetrendasexpected,reflectingtheintrinsicevolutionofrisk,towhichwecanaddtwoerrorterms:
-Theestimationerrorcorrespondingtotheerrormadeinestimatingtheparametersofthemodel.
-Theprocesserrororerrorprocess, linkedtothevariabilityoftherandomvariablesthatmakeupthemodel.
Examples of trends: general decline in the mortality rate linked to the improvement of livingconditions.
Examplesoffluctuationsrelatedtothetrend:underestimationoroverestimationofclaimsreportsfordisabilityordependence,refusalsoracceptancesofclaimsmoreorlessadvanced.

Examples of break linked to a crisis: Banking and financial crisis of autumn 2008, Europeanperipheralcrisisduringtheyears2010and2011.
Examples of break unrelated to a crisis: Misreading / application of the general conditions of acontract,massivefraud,appearanceorcureofadreadeddisease.
We thus propose to associate the strong drifts (permanent or temporary) with the level riskassociatedtotheriskofmodel.

We can talk about a breakwhenwe notice a significant difference between the observed and anestablishedrisklimit(boundsofconfidenceintervals,fixedquantiles)and/orasustainableincreaseoftheriskfactorthatcanbeexplainedbyoneormorefactor,internalorexternal.
1.1. Whichphilosophytoadoptintheownriskassessment?
Oneofthemainproblemsofinsurersisthereconciliationofthefollowingfivevalues:
We consider that abreak in trend is related to a strongdecorrelationor a reconciliationbetweenthese different quantities. Therefore, more monitoring of these values, including the quantityreported,shouldbeestablished.Itisthennecessarytospeakofevolutionof"ourvision"oftheriskratherthanevolutionoftheriskassuch.

To identify a relevant ORSA scenario is to identify the possible causes of decorrelation orapproximationbetweenthesequantities.
The stochastic simulation logic around the trend (often adopted in the calculations of economiccapital)makesitpossibletotakeintoaccounttheprobabilisticdescriptionofthemodeledquantity:therecanbenoguaranteethattheimpactofabreakinfuturetrendiscontainedinthesedifferentvalues.Dependingonthescenarios(especiallythosewithastrongstallinthetrendthatmayresultinexceeding the risk limit set in the ORSA framework), an ORSA add-on capitalmay be required. Achallenge of risk appetite goals is also possible. Governance should allow rapid adaptation topotentialnewsituations.
1.2. RiskmappingMostFrenchinsurersalreadyhaveawell-establishedriskmapthatisupdatedregularly.Ourworktoimprove the ERM framework by integrating the management of biometric and behavioral trendbreaks,requiresarefinementofthismapping,ascertainspecificrisksemerge:endogenous(internaltothesystem)andexogenousrisks.

Mostinsurershadasprioritiesuntiltheendof2015theimplementationofSolvencyIIwitheconomiccapital calculations (and development of adapted tools), the aggregation of risks and especially astandardizationofsystemsandcalculations.comingfromvariousnetworks.Theyfounditdifficulttofind sufficient resources to easily deploy a comprehensive risk management strategy, particularlyfocusedonthecoreoftheirbusiness:underwritingrisks.
WeaskedsomeinsurancecompanydirectorsabouttheirORSApolicyanditshowsthatunderwritingrisk loss levels were calculated using risk models calibrated using historical volatilities. Thesevolatilitiesmaybepro-cyclicaland/ornot-adaptedtotheriskactuallyincurred:

-Theycanbetaintedwithdataerrors,changeofscope,etc.
Moreover, the estimation models most often make an assumption of normality of the residues,hence the appearance of the leptokurtic static problem (thinness of the densities). One of theillustrationsthatcanbemadetocharacterizethisphenomenonistheriskoftotal lapseofasavingportfolio(seesection4).

2.2. CreatingtheTrendBreaksCatalogIn order to improve the ERM risk monitoringprocess, it can be very useful to establish a basisthat includes all the characteristics of the trendbreaksidentifiedonthetargetedunderwritingrisks:itistheCatalogoftrendbreaks.
Weproposetoestablishthefollowingindicators:
We also propose to integrate trend breaks observed on external perimeters (by checking at leastordersofmagnitude,aswellastheirabilitytohaveanimpactontheinternalperimeterstudied).Afterthecatalogoftrendbreakshasbeencreated, it ispreferabletosubmit it forvalidationtoallthe business experts who contributed to its completion. It can then be presented to the RiskCommittee.This catalog can be completed by a ranking of the origins of trend breaks that had the greatestimpactonthemagnitudeobserved.ThismakesitpossibletoraisetheawarenessoftheBusinessesandespeciallyall thedirectorsof insurancecompaniesabout the causesofnegative trendbreaks,butalsoaboutthemostefficientManagementActions-MA-.
2.3. ProspectiveAnalysisandCalibrationoftheFutureEvolutionofRisks2.3.1. Short-termanticipatorymeasures:theuseofsensors
Theadvantageofthisanticipatorystep is totake intoaccountrecent informationthatcanconfirmeither constancy or break of a trend in the short term (current year and next year),whether it isvisible inthedataornot.Toberesponsive,oneshouldnotwait for theestablishmentofaccountsandtheliquidationofclaims.
Inpractice, thisanticipationexercisecanbedifficult: theorientationof the trend (providedby theestimation models) is not easy, the opinions of the business experts can diverge, certain factorsinternalorexternaltothecompanycanchangetheexpectedeffects.
InourERMapproach,weproposeastate-basedanticipationmodelthatusesdatathatisinternalorexternaltoinsurancecompanies–wewillcallthemsensors-allowingshort-termdisruptioneffectstobe taken intoaccount. Thepurposeof thismethod, in addition toanticipation, is tobeable toenrichtheoverallriskassessment.

These sensors arenot always "ahead"with respect to risk factordrift, but they can identify trendbreaks and serve aswarning signalswhen their evolution rate change.We can therefore considerthemasriskindicators.

2.3.2. CompletionoftheCatalogoftrendbreaksbyprobableoutcomes
In order to establish more relevant ORSAoutcomes (or to validate the relevance ofalready established outcomes), we propose tosupplement the previous Catalog of potentialfuture trend breaks by integrating outcomesfrom experts. These outcomes can be of threekinds:theoutcomesofbreaksalreadyobserved(withthesamecharacteristics),theoutcomesofbreaks already observed with modifiedcharacteristicsandthenewoutcomes(seegraphbelow).
An"interview"approachwasfavoredby interviewingseveralbusinessexpertsabouttheoutcomesofpossiblebreaks.Eachinterviewcanbeprecededbythepresentationofextractsfromthecatalogofpastbreaks.Thesummaryoftheseinterviewsconductedinthecontextofthisarticleisinsection2.3.4.

judgewhether this strong drift can be capturedby the fixed quantile of the risk factorwithin theframeworkoftheORSA,otherwisetheintegrationofthisthirdcomponentmaylimittheriskofnon-consistency of the economic capital by involving a capital add-on. This jump process is similar tothoseusedinfinancetomeasurefinancialrisks.Itisalsousedinnewmodelsforassessingmortalityrates(seeJamesKirkbyandIainCurrieworks).ThetechnicalaspectsrelatingtothesimulationofriskfactorsaredescribedinsectionErreur!Sourcedurenvoiintrouvable..
Thisscenariodeterminationapproachhasthefollowingadvantages:
-Goodapprehensionatalllevels(businessandmanagement)ofpossiblescenarios.
-Acombinationofscenariosfromthemodelsandexperts'statements.
-Anautomaticdeterminationofthelaws/trajectoriesrelatingtotherisklimitsestablished(withintheframeworkoftheriskappetite)amongasetofpossibletrajectories,relatingtoallthepossiblescenarios.
Weproposethefollowingapproach.WhenthemostfearedORSAscenario(foragivenrisk)andonwhichwebasedtoquantifytheORSAcapitalis:
- a trend and diffuse evolution in time of the risk: taking into account the quantile at x% of thecorrespondingriskfactor,withoutintegrationofjumps;
-apermanentordurablestrongdrift:taking intoaccountthequantileatx%ofthemodeling,withintegrationofjumps;
It is therefore necessary, in addition to listing themost feared scenarios, to indicate their nature(type of break) in order to be able to quantify the ORSA add-on capital, their probability ofoccurrence during the ORSA Business Plan time horizon, their latency period before occurrence(certain eventswill have no impact on the risk factors before a certain period of application) andtheirdurationofimpact.

AfirstreasonisthattheORSAscenario inquestionmaynotbeaquantile ifwehavelowhistoricalvolatilityorwearefacingamodelspecificationerror.Asecondreason is thatonemustconstantlyseekacorrespondencetoeachscenarioaccordingtoexperts.Thisisanoperationaldifficultyforthecalculations.Athirdreasonisthatthejumpprocessprovidesvariantsforeachsimulation:variationswithrespecttointensityanddurationarethusintroduced.
Amplitudecalculation
The amplitude calculation for the past scenarios is done by making the difference between theprediction (including the trend) and the observed one. This is a prudent measure. Indeed thecalculationcanalsobedonebyconsideringthedifferencebetweenarisklimit(confidenceintervalslimits)andnoticed.

This algorithm has several advantages including thespeedof detectionof slowbreaks and theminimizationof the rateof false alarms. The thresholdlevels associated with this algorithm may be the same as those mentioned above. Despite theeffectiveness of this algorithm it has various limitations.

Furthermore, it is hoped that the estimatingperiodsof central lapse rates lawswill be revised: infact, they include periods [2008-2011] deemed volatile, with an upward trend in risk.

6. CONCLUSION
The aim of this article was to propose a pragmaticmechanism for analyzing andmanaging trendbreaksforbiometricandbehavioralrisks.Giventhelimitationsofthemodels(integrationofrandomGaussian distribution), we present in this paper a method combining both historical scenarios,probable scenarios (according to experts) and scenarios derived from the models (oftenretranscribing only process and estimation errors). The idea is to have for each biometric andbehavioralriskapanelofscenariosinordertoconfrontthemtodrawthemostrelevantscenario.Itwillbeeasiertodescribetheconditionsinascenariothatleadtochangingtheriskfactoruptothequantiledefinedintherisklimits.
Our ERM approach based on the identification, evaluation, quantification and treatment of risksallows:
-tofacilitatethemonitoringofriskovertime,
-toanalyzeandexplainmoreeasilyonthemajorfactorsofthepasttrendbreakswhichmayhaveweighedonthestrategicobjectives,
-toanticipatefuturechanges,especiallywiththeemergenceofnewcustomerbehaviors,
-improvetheriskmanagementprocess,
-facilitatethestrategicchoicesofthegoverningpersonswithfasteraccesstorelevantinformation
That said, despite all anticipation efforts, somephenomenawill beunpredictable and canonly beobservedretroactively: thebestmanagementmethodremainsriskgovernance.The lattermustbereactive, efficient and endowed with "connected" human resources with the evolutions of theeconomic,socialandregulatoryenvironment.
