Chapter 22 Pricing (4) Options and guarantees Flashcards
Mortality and morbidity options
- These are situations where the policyholder can choose to extend the term or increase the level of cover at normal premium rates but without providing further medical advice.
- Options have little impact on a one-year contract (PMI) , if the terms and acceptance are variable every year.
Terms and conditions for options
- It is common for LTCI policies to include options:
- to purchase additional assurance without providing evidence of health at normal premium rates at date which option was exercised.
- to renew a LTCI policy eg a term CI insurance policy at the end of it original term without providing additional evidence of health.
- to reinstate mortality cover aafter an accelerated critical illness plan has paid out on a specified disease event.
- the terms and conditions under which options can be exercised should be clearly set out.
- eg every 5 years
- the extent of option shhould be clear
- eg additonal SI cannot exceed original SI.
-terms and conditions of option aim to reduce anti-selection.
What are the cost of options?
- the value of excess of premium that should be charged in light of full underwriting information over the normal premium rate that is charged.
- for some lives the option will have no cost.
- the cost of an option depends on the health status of those that choose to exercise the option, and the proportion of lives that choose to exercise the option.
-cost of option = proportion of those exercising option * Average extent that health of lives is worse than normal.
Factors affecting health options are?
- The term of the policy with the option
- The number of times the policyholder gets the chance to exercise the option.
- Conditions attaching to exercising the option
- Encouragement given to policyholders to exercise the option.
- The extra cost to policyholder who exercises the option
- selective withdrawals
Options: Constant monitoring
- whatever the current experience, the value of options must be kept under constant review.
- it would not be unthinkable for a health insurance option to come into the money, much as deferred pension policies (despite being relatively worthless at the time of sale)
Valuing a mortality/morbidity option requires two extra assumptions as part of the pricing basis:
- the probability of the option being exercised
- the expected mortality/morbidity of the lives who choose to exercise the option.
What three methods can be used to value options?
- north american method
- conventional method
- statistical method
The North american method requires two additional items:
- a double(or triple) decrement table for lives who have not yet exercised the option, with decrements of death/disability and exercising the option represented by dependent rates of decrement at age x of (aq)d,x and (aq)w,x respectively.
- displayed in double decrement table as (ad)d,x and (ad)w,x number of decrements out of (al)x lives.
Limitations of the North american method
- it is often difficult to obtain sufficient data to estimate all the decrement rates
- for a new line of business there will be no direct experience
- conventional method is often preferred choice.
The conventional method assumptions
- all the lives eligible to take up the option will do so
- the mortality/morbidity experience of those who take up the option will be ultimate experience that corresponds to the select experience that would have been used as a basis if underwriting had been completed as normal when the options was exercised.
-morbidity/mortality used is not usually assumed to change over time, so only the data required are select & ultimate tables used in original pricing basis.
limitations of the conventional method
- it is not possible to use this method when there are many policy dates which an option may be exercised.
- the approximate approach taken here is that the worst option from the financial point of view is chosen with probability one.
Stochastic modelling
- Future experience is projected and the numbers taking up the various options and their subsequent claim propensities are investigated.
- A large number of simulations will be tested and the cost of the option will be calculated with a particular statistical degree of adequacy.
Guarantees: Resilience testing of premium rates
- this is sensitivity testing
- premium rates need to be asses on a resilience basis to judge whether, in the absence of an ability to change the premiums/benefit relationship, the premium charged will be sufficient to meet all outgoings with an agreed level of confidence.
- this will require more establishment of reserves in earlier years.
Guarantees: Adequacy of reserves in pricing
- actuary needs to incorporate into premium a loading to cover the additional cost of providing the guarantees including cost of holding the guarantee reserves.
- if the true cost of guarantees appears in the premiums, it may encourage many to move to a reviewable contract where the same benefits will cost less.
Guarantees:Regulatory approval
-local regulator will normally want to see evidence of the techniques employed and their output, to judge the adequacy of the premiums and reserves required.
