Q

Mortality and morbidity (health) options

A

to the extent the option might be exercised by someone in poor health, the insurer will bear a cost
- the difference between the ordinary premium rate granted and that which would have been granted had the life been underwritten
- investment guarantees not the norm in health and care policies

Q

Cost of option

A

value of excess premium that should, in light of full underwriting, have been charged for the additional insurance over the normal premium rate charged
- cost of a health option ~ (proportion of lives exercising option) x (average extent that health of lives exercising the option is worse than normal)

Q

Factors affecting health options

A
  • term of the policy (longer –> p/h longer to exercise)
  • number of times policyholder has to exercise option
  • conditions attaching to exercise of the option
  • encouragement given to p/h to exercise - if take-up low, tends to be only those who have most to gain from exercise
  • extra cost to policyholder who exercises options (e.g. increase in premiums steep, healthier policyholders may opt to take out cover elsewhere for cheaper)
  • selective withdrawals (withdrawal by healthy lives before option data reduces the income would have been expected to receive from the whole risk pool)

Q

Courses of action company might follow for onerous option

A
  • reduce encouragement given to policyholders to exercise the option
  • reinsure some of the increased risk
  • remove option for new business
  • increase standard premium rates
  • make option less attractive to reduce take-up rate
  • limit number of times the option can be exercised

Q

Valuing a mortality/ morbidity option

A

Requires extra assumptions as part of the pricing basis
- probability the option will be exercised
- expected mortality/ morbidity of the lives who choose to exercise the option

Two methods
- North American method
- conventional method

(stochastic modelling - third method establish core cost of option)

Q

North American method

A

requires extra data on likelihood of option being exercised and morbidity of those doing so
- double or triple decrement table for lives who have not yet exercised the option
- mortality/ morbidity table for lives who have exercised the option

  • often difficult to obtain sufficient data to estimate all decrement rates required
  • for new LoBs, there will be no direct experience

Q

Conventional method

A
  • assumes all lives eligible to take up the option will do so
  • mortality of those who take up the option will be the Ultimate experience, corresponding to the Select experience that would have been used as a basis if underwriting had been completed as normal when the option was exercised
  • ## copes less easily with multiple options

Q

Stochastic modelling

A
  • future experience projected and numbers taking up various options and subsequent claim propensities are investigated
  • subdivide population of policyholders into different risk categories
  • proportions ending up in each risk group, average claim experience of each risk group at option date could be modelled as stochastic variables
  • require probability distributions for these
