(1) Exchange-traded derivatives with a positive fair value of $36 in 2020 ($19 in 2019) are excluded from the table above, as they are subject to daily margining requirements. Our credit exposure on these derivatives is with the exchanges and clearinghouses.

(2) Used to determine the credit risk exposure if the counterparties were to default. The credit risk exposure is the cost of replacing, at current market rates, all contracts with a positive fair value.

(3) The credit risk associated with derivative assets subject to master netting arrangements is reduced by derivative liabilities due to the same counterparty in the event of default or early termination. Our overall exposure to credit risk reduced through master netting arrangements may change substantially following the reporting date as the exposure is affected by each transaction subject to the arrangement.

10.AInsuranceContractLiabilities 10.A.iDescriptionofBusiness The majority ofthe productssoldby the Company are insurance contracts.These contractsinclude allformsoflife,healthandcriticalillness insurance soldtoindividualsandgroups,life contingentannuities,accumulationannuities,andsegregatedfundproductswithguarantees.

10.A.iiMethodsandAssumptions General

The liabilitiesforinsurance contractsrepresentthe estimatedamountswhich,togetherwithestimatedfuture premiumsandnetinvestment income,willprovide foroutstandingclaims,estimatedfuture benefits,policyholders' dividends,taxes(otherthanincome taxes),andexpenseson in-force insurance contracts.

Indeterminingourliabilitiesforinsurance contracts,assumptionsmustbe made aboutmortality andmorbidity rates,lapse andotherpolicyholder behaviour("policyholderbehaviour"),interestrates,equity marketperformance,assetdefault,inflation,expenses,andotherfactorsoverthe life of ourproducts.Mostofthese assumptionsrelate toeventsthatare anticipatedtooccurmany yearsinthe future.Assumptionsrequire significant judgmentandregularreviewand,where appropriate,revision.

We use bestestimate assumptionsforexpectedfuture experience andapply marginsforadverse deviationstoprovide foruncertainty inthe choice ofthe bestestimate assumptions.The amountofinsurance contractliabilitiesrelatedtothe applicationofmarginsforadverse deviationstobest estimate assumptionsiscalledaprovisionforadverse deviations.

Best EstimateAssumptions

Bestestimate assumptionsare intendedtobe current,neutralestimatesofthe expectedoutcome asguidedby Canadianactuarialstandardsof practice.The choice ofbestestimate assumptionstakesintoaccountcurrentcircumstances,pastexperience data(Company and/orindustry),the relationshipofpasttoexpectedfuture experience,anti-selection,the relationshipamongassumptions,andotherrelevantfactors.Forassumptions oneconomicmatters,the assetssupportingthe liabilitiesandthe expectedpolicy forasset-liability managementare relevantfactors.

MarginsforAdverseDeviations

The appropriate levelofmarginforadverse deviationsonanassumptionisguidedby Canadianactuarialstandardsofpractice.Formost assumptions,the standardrange ofmarginsforadverse deviationsis5%to20%ofthe bestestimate assumption,andthe actuary choosesfrom withinthatrange basedonanumberofconsiderationsrelatedtothe uncertainty inthe determinationofthe bestestimate assumption.The levelof uncertainty,andhence the marginchosen,willvary by assumptionandby line ofbusinessandotherfactors.Considerationsthatwouldtendto indicate achoice ofmarginatthe highendofthe range include: • The statisticalcredibility ofthe Company'sexperience istoolowtobe the primary source ofdataforchoosingthe bestestimate assumption • Future experience isdifficulttoestimate • The cohortofriskslackshomogeneity • Operationalrisksadversely impactthe ability toestimate the bestestimate assumption • Pastexperience may notbe representative offuture experience andthe experience may deteriorate

Provisionsforadverse deviationsinfuture interestratesare includedby testinganumberofscenariosoffuture interestrates,some ofwhichare prescribedby Canadianactuarialstandardsofpractice,anddeterminingthe liability basedonthe range ofpossible outcomes.A scenariooffuture interestratesincludes,foreachforecastperiodbetweenthe statementoffinancialpositiondate andthe lastliability cashflow,interestratesfor risk-free assets,premiumsforassetdefault,ratesofinflation,andaninvestmentstrategy consistentwiththe Company'sinvestmentpolicy.The startingpointforallfuture interestrate scenariosisconsistentwiththe currentmarketenvironment.Iffewscenariosare tested,the liability would be atleastasgreatasthe largestofthe outcomes.Ifmany scenariosare tested,the liability wouldbe withinarange definedby the average ofthe outcomesthatare above the 60thpercentile ofthe range ofoutcomesandthe correspondingaverage forthe 80thpercentile.

Provisionsforadverse deviationsinfuture equity returnsare includedby scenariotestingorby applyingmarginsforadverse deviations.Inblocksof businesswhere the valuationofliabilitiesusesscenariotestingoffuture equity returns,the liability wouldbe withinarange definedby the average ofthe outcomesthatare above the 60thpercentile ofthe range ofoutcomesandthe correspondingaverage forthe 80thpercentile.Inblocksof businesswhere the valuationofliabilitiesdoesnotuse scenariotestingoffuture equity returns,the marginforadverse deviationsoncommonshare dividendsisbetween5%and20%,andthe marginforadverse deviationsoncapitalgainswouldbe 20%plusanassumptionthatthose assetsreduce invalue by 20%to50%atthe time whenthe reductionismostadverse.A 30%reductionisappropriate foradiversifiedportfolioofNorthAmerican commonsharesand,forotherportfolios,the appropriate reductiondependsonthe volatility ofthe portfoliorelative toadiversifiedportfolioof NorthAmericancommonshares.

Inchoosingmargins,we ensure that,whentakenone atatime,eachmarginisreasonable withrespecttothe underlyingbestestimate assumption andthe extentofuncertainty presentinmakingthatassumption,andalsothat,inaggregate,the cumulative impactofthe marginsforadverse deviationsisreasonable withrespecttothe totalamountofourinsurance contractliabilities.Ourmarginsare generally stable overtime andare generally only revisedtoreflectchangesinthe levelofuncertainty inthe bestestimate assumptions.Ourmarginstendtobe atthe highendofthe range forexpensesandinthe mid-range orhigherforotherassumptions.Whenconsideringthe aggregate impactofmargins,the actuary assesses the consistency ofmarginsforeachassumptionacrosseachblockofbusinesstoensure there isnodouble countingoromissionandtoavoid choosingmarginsthatmightbe mutually exclusive.Inparticular,the actuary choosessimilarmarginsforblocksofbusinesswithsimilar characteristics,andalsochoosesmarginsthatare consistentwithotherassumptions,includingassumptionsabouteconomicfactors.The actuary is guidedby Canadianactuarialstandardsofpractice inmakingthese professionaljudgmentsaboutthe reasonablenessofmarginsforadverse deviations.

Mortality

Mortality referstothe ratesatwhichdeathoccursfordefinedgroupsofpeople.Life insurance mortality assumptionsare generally basedonthe pastfive totenyearsofexperience.Ourexperience iscombinedwithindustry experience where ourownexperience isinsufficienttobe statistically valid.Assumedmortality ratesforlife insurance andannuity contractsinclude assumptionsaboutfuture mortality improvementbasedonrecent trendsinpopulationmortality andouroutlookforfuture trends.

Morbidity

Morbidity referstoboththe ratesofaccidentorsicknessandthe ratesofrecovery therefrom.Mostofourdisability insurance ismarketedona groupbasis.We offercriticalillnesspoliciesonanindividualbasisinCanadaandAsia,long-termcare onanindividualbasisinCanada,andmedical stop-lossinsurance isofferedonagroupbasisinthe U.S.InCanada,groupmorbidity assumptionsare basedonourfive-yearaverage experience, modifiedtoreflectany emergingtrendinrecovery rates.Forlong-termcare andcriticalillnessinsurance,assumptionsare developedin collaborationwithourreinsurersandare largely basedontheirexperience.Inthe U.S.,ourexperience isusedforbothmedicalstop-lossand disability assumptions,withsome considerationofindustry experience.

PolicyholderBehaviour

Lapse

Policyholdersmay allowtheirpoliciestolapse priortothe endofthe contractualcoverage periodby choosingnottocontinue topay premiumsor by surrenderingtheirpolicy forthe cashsurrendervalue.Assumptionsforlapse experience onlife insurance are generally basedonourfive-year average experience.Lapse ratesvary by plan,age atissue,methodofpremiumpayment,andpolicy duration.

PremiumPaymentPatterns

Foruniversallife contracts,itisnecessary tosetassumptionsaboutpremiumpaymentpatterns.Studiespreparedby industry orthe actuarial professionare usedforproductswhere ourexperience isinsufficienttobe statistically valid.Premiumpaymentpatternsusually vary by plan,age at issue,methodofpremiumpayment,andpolicy duration.

Expense

Future policy-relatedexpensesinclude the costsofpremiumcollection,claimsadjudicationandprocessing,actuarialcalculations,preparationand mailingofpolicy statements,andrelatedindirectexpensesandoverhead.Expense assumptionsare mainly basedonourrecentexperience usingan internalexpense allocationmethodology.Inflationary increasesassumedinfuture expensesare consistentwiththe future interestratesusedin scenariotesting.

Investment Returns

InterestRates

We generally maintaindistinctassetportfoliosforeachmajorline ofbusiness.Inthe valuationofinsurance contractliabilities,the future cashflows frominsurance contractsandthe assetsthatsupportthemare projectedunderanumberofinterestrate scenarios,some ofwhichare prescribed by Canadianactuarialstandardsofpractice.Reinvestmentsanddisinvestmentstake place accordingtothe specificationsofeachscenario,andthe liability issetbasedonthe range ofpossible outcomes.

Non-FixedIncome RatesofReturn

We are exposedtoequity marketsthroughoursegregatedfundproducts(includingvariable annuities)thatprovide guaranteeslinkedtounderlying fundperformance andthroughinsurance productswhere the insurance contractliabilitiesare supportedby non-fixedincome assets.

Forsegregatedfundproducts(includingvariable annuities),we have implementedhedgingprogramsinvolvingthe use ofderivative instrumentsto mitigate alarge portionofthe equity marketriskassociatedwiththe guarantees.The costofthese hedgingprogramsisreflectedinthe liabilities. The equity marketriskassociatedwithanticipatedfuture fee income isnothedged.

The majority ofnon-fixedincome assetsthatare designatedasFVTPLsupportourparticipatinganduniversallife productswhere investmentreturns are passedthroughtopolicyholdersthroughroutine changesinthe amountofdividendsdeclaredorinthe rate ofinterestcredited.Inthese cases, changesinnon-fixedincome assetvaluesare largely offsetby changesininsurance contractliabilities.

AssetDefault

Asrequiredby Canadianactuarialstandardsofpractice,insurance contractliabilitiesinclude aprovisionforpossible future defaultofthe assets supportingthose liabilities.The amountofthe provisionforassetdefaultincludedinthe insurance contractliabilitiesisbasedonpossible reductions infuture investmentyieldthatvary by factorssuchastype ofasset,assetcreditquality (rating),duration,andcountry oforigin.The assetdefault assumptionsare comprisedofabestestimate plusamarginforadverse deviations,andare intendedtoprovide forlossofbothprincipaland income.Bestestimate assetdefaultassumptionsby assetcategory andgeography are derivedfromlong-termstudiesofindustry experience and the Company'sexperience.Marginsforadverse deviationare chosenfromthe standardrange (of25%to100%)asrecommendedby Canadian actuarialstandardsofpractice basedonthe amountofuncertainty inthe choice ofbestestimate assumption.The creditquality ofanassetisbased onexternalratingsifavailable (publicbonds)andinternalratingsifnot(mortgagesandloans).Any assetswithoutratingsare treatedasifthey are ratedbelowinvestmentgrade.
