Cost Of Guarantees And Options Flashcards
List examples of investment guarantees
1) Guaranteed minimum maturity values (for both unit-linked and non-linked endowment contracts)
2) Guaranteed minimum surrender values (for both unit-linked and non-linked endowment contracts)
3) The ability to convert a lumo sun into an annuity or vice versa on guaranteed terms
What liability is created by an investment guarantee?
The excess of the guaranteed amount over the cost that would have been incurred at the time in the absence of a guarantee
List the methods that may be used to determine the liability created
1) Option-pricing techniques
2) Stochastic simulation
Option-pricing techniques to value liabilities created by investment guarantees
The value of the liabilities will be similar to the cost of a derivative which covers a similar guarantee or option to that which the company is offering. Only works if there exists a sufficiently close hedging asset to match the guarantee offered
Stochastic simulation to value liabilities created by investment guarantees
The extra sums likely to be needed under the guarantee can be modelled stochastically by running a simulation of investment returns thousands of times
List examples of mortality options
1) Extending the term without providing further evidence of health
2) Increasing the level of cover at normal premium rates without providing further evidence of health
How may mortality options be valued?
Using a discounted cashflow model with assumptions for…
- option take-up rate
- benefit chosen
- mortality of those that exercise the option
- mortality of those that do not
- expenses relating to the option
How may option take-up rates be set?
1)
- Assume all eligible policyholders take up the option
- Assume maximum benefit is always taken
- Assume the worst-case scenario from the insurer’s PoV
This method is simplistic but unlikely to be borne out in practice.
2)
- Assume a more sophisticated take-up rate
- These may vary by exercise rate or alternative options
- These are based on past experience
This method may be more realistic but it may be difficult to obtain the necessary data
Cost of a mortality option =
= (proportion of lives exercising option).(average health of lives exercising option)
List the factors affecting mortality options
SCENTE
Selective withdrawals
Conditions attaching to exercising the option
Encouragement given to policyholders to exercise the option
Number of times the policyholder gets the chance to exercise the option
Term of policy with the option
Extra cost to the policyholder who exercises the option
How might the higher mortality of option-exercising individuals be incorporated into the model
1) A higher % of base mortality
2) An age loading may be applied
3) Ultimate mortality may be used for those who exercise the option while select is used for those who don’t
