Looking Back:Term Insurance in Canada
Term In Canada – A ‘Typical’ productlooks like:• Level Premiums for Fixed Term Lengths (T10 and
T20 most common)• Renewable and convertible (age limits apply)• Issue ages 15-75• Issue face amounts from $50,000 to ?• Can be single or joint first-to-die• Multiple underwriting classes (e.g. – preferred or
“super-preferred”)
Term Sales in Canada• Based on recent sales activity, a typical year of
Term sales would look like:
Risk Profile for (Re) Insurers• Relatively low on interest rate risks.
• Shorter Term liabilities
• Relatively high on policyholder behavior risk• Lapses (Anti-Selective)• Conversions (a little Anti-Selective)• Mortality
Key Turning Point• Around Y2k, Term in Canada migrated from Single
Scale Premiums to Select And Ultimate.
Key Turning Point• New financial incentive to lapse coverage at the
end of the initial term and purchase a new planwith new underwriting (anti-selection).
• Competitive Pressures have increased the incentiveover the last 10 years.
• Significant impact on Lapse & Mortality.• Experience Emerging as we speak!

What are “experience studies”?
In a study of 500 people we asked“On a scale of 1-10, how wouldyou rate your experience…”
Experience Studies in insurance aremuch more interesting!**

What are experience studies ?• A report showing something about some aspect
of the performance of the business• We’re focused on those reports which try to
answer the questions• What kind of mortality rates are we seeing?• What kind of lapse rates are we seeing?
Mortality Experience Analysis
• A common way of reviewing mortality experience iscomparing how actual experience compares to what wasexpected (or priced for)

97.5% Confidence IntervalIn this case, observing 4 deaths is inthe “normal” range. (But just)
So is seeing 4 deaths “credible”?
It depends.
Credibility• It depends. Judgement is required• We expected 1-2 deaths (1.5), consistent with a
mortality rate of 0.5% which was based on amuch larger sample (e.g. the experience of allinsurance companies). (Prior Beliefs)
• However in the industry study, all of thoseinsurance companies obtained medical evidence.
• A: If our company also obtained medical evidence?• B: If our company did not obtain medical evidence?
Credibility Application• Updated mortality:
• I update my mortality rate assumption to a blend of what thedata is telling me (mortality rate of 1.33%) and the industryaverage (0.5%).
• New Mortality Rate = Z% *1.33% + (1-Z%)*0.5%• Z% = credibility of your new data
• If A is true.• Z% is small. (e.g. 5%-10%) My own data is not credible.• (However, maybe there’s another important difference that
I’m not aware of)• If B is true.
• Z% is large. (e.g. 90%-95%). Although not statisticallysignificant, what the data is showing is more important thanwhat I assumed. I will try to update my “prior beliefs”.
How to estimateZ% is complex

Past vs Future- Experience• So all the studies have focused on Term 10
policies issued more than ten years ago.• Those policies have lower premium jumps than
Term 10 policies issued today.• Therefore how can we predict what are the most
appropriate lapse and mortality assumptions toprice and value Term 10 policies issued today?
Past vs Future-Lapse• Get clues from US experience-where large jump
experience exists• Tricky, since US T10 products are quite different.
They are the same for 1-10, and year 11 only.
• If T10 premiums jumps are approximately 7xwhat does the US experience say lapse rate is ?

Term Mortality Models
Mortality deterioration 101• Development of the formula
• Let’s assume that 85% will lapse just before the end of the 10thpolicy anniversary
• What will be the mortality assumption of the remaining group ?• Model presented by Jeffery Dukes and Andrew MacDonald in
1980
• To determine the mortality of the 15% who persist, we need tomake a few assumptions about the 85% who lapsed 85
Mortality deterioration 101• We need to split the 85 men who lapsed into 3
distinct groups• GROUP 1 = Assumption #1, the underlying (UL)• % of lapses already embedded in the experience of the mortality
table.
Assume 5
85
5• They are assumed to
have the samemortality as the entiregroup just before theyrenew (0.00482)
Mortality deterioration 101• The 80 (85 – 5) men left are called additional
lapses• GROUP 2 = Assumption #2, the select men (SL-> select
proportion or effectiveness)
80 • Those who can get a brand newpolicy and pay a cheap T10 priceagain (they are now age 45)
• We will assume it’s 60% ofthe 80 men
• Their mortality is assumed to bethe same as newly underwritteninsured lives
Q[45] = 0.00283 < Q[35]+10 = 0.00482
4860% proportionof selectivelapse (60% X80)
Mortality deterioration 101• The 32 (85 – 5 – 48) men left are the average
men• GROUP 3 = Assumption #3, the average men
32• They are assumed to
have the same mortalityas the entire group justbefore they renew(0.00482)
Mortality deterioration 101• Key principles
• Conservation of deaths principle: The total number ofdeaths for a group of policyholders is the sameregardless of how the group is split
• Average, selective and underlying lapses occur only atpolicy anniversaries

Looking Forward:Term Insurance in
CanadaMark Andrews
Challenges for Direct Writers• Though we can make educated guesses, we can’t
be sure of what the future holds in terms of:• Lapses• Mortality• Techniques for predicting the above• Competitor Actions• Reinsurer Actions• Capital Requirements
Challenges for Direct Writers• We know significantly more about managing this
risk than we did even a few short years ago:• Premium increases at renewal can be a valuable input
in predicting lapse rates (and anti-selection).• Increases are materially higher today than what our
experience is based on.
What Can We Do?• Changing the Product Design?
• Changing the nature of premiums after the initial levelterm?
• Changing the nature of writing business?• Simplified Issue Term products introduced in 2015.
(Up to $500k of coverage).• Direct to consumer products (could change behaviour
landscape).
• Changing Reinsurance?• New solutions for managing lapse and mortality risk?
