Car - Assumptions Reserves Flashcards
What makes up morbidity rates? (5)
1 CI incidence rates 2 LT sickness transfer probs 3 LTCare transfer probs 4 PMI incidence rates 5 Other claim inception
Principles of Setting Assumptions? (8)
1 Use - Consider the use to which they’ll be put
2 Focus - Take care over most financial significant ones
3 Consistency between various assumptions
4 Legs/Regs considered
5 Needs of client considered
6 Accurate - Parameters to be derived as accurately as possible from data
7 Relevant - Data should be relevant to the risks of the policies
8 Flex - Bases for valuations/reserves must be flexible to reflect changes in risk
What makes up demographic assumptions?
1 Mortality/Morbidity
2 Claim incidence/recovery rates
3 Lapse/Renewal Ratesetter
What makes up financial assumptions? (7)
1 Benefit sizes 2 Benefit inflation 3 Expenses 4 Expense inflation 5 Commission and clawback rates 6 Investment returns 7 Tax (profits/inv income/premiums
What NB assumptions are there?
1 Volume 2 Mix by: Avg policy size Product Distribution channel Territory Gender Occupation
What things make up and effect assumptions?
1 Solvency capital requirements 2 Discount rate (risky or risk neutral) 3 MADs 4 Profit criteria 5 Demographic Assumptions 6 Financial assumptions 7 NB volume/mix (type/source/size)
Types of long term insurance reserves?
1 Policies (discounted value of future expected claims/expenses/premiums)
2 IBNR claims
3 Reported but not yet settled
4 Option reserves (costs of options/guraantees)
5 Unearned premium reserve/unexpired risk reserve for group
6 Mismatch reserve
Type of short term insurance reserves
1 Unearned premium reserve 2 Unexpired risk reserve 3 Ooutstanding claims reserve 4 IBNR 5 Incurred but not enough reported 6 Equalisation/catastrophe reserve 7 Claims in transit 8 Mismatch reserve
Purpose of calculating technical reserves
1 Liabilities for published/solvency/IM accounts
2 M&A valuations
3 Investment strategy
4 Reinsurance arrangements
5 Estimate recent cost of claims for pricing
Principles of Setting Reserves
1 Set to ensure all liabilities out of insurance contracts can be met
2 Prudent valuation of all future liabilities for all existing policies including:
3 Guarantees and options
4 Expenses including commission
5 Credit for future premiums
6 Prudent is not best estimate, should include MADs of relevant factors
7 Take into account NTC and valuation method of relevant each policies assets
8 Appropriate generalisations/approximations allowed
9 Interest rate (where appropriate) prudent, taking into account currency of polciy, yields on current assets and on future investments
10 Prudent choice of demographic/persistency/expense assumptions.. 11 Having regard to type of insurance/location of policyholders/admin costs/commission expected
12 Methods and bases in valuation should be disclosed
13 Calculation method should recognise profits approprtiately over duration of each contract, no discontinuities
14 Expenses should not be less than prudent estimate of them
What things effect the implementation of principles of reserves?
1 Professional guidance
2 Supervisory regime requirements e.g. best estimate + margins instead of prudent reserves
When is a case-by-case method used in short term insurance reserving? What factors taken into account? How are short term reserves calculated if not case-by-case?
1 Large/unusual claims 2 Statistical estimation if not case-by-case 3 Procedure type 4 Hospital used 5 Which surgeon/consultant/other 6 Policy coverage (any excess/max claims etc.) 7 Age/Sex/Past claims 8 Current levels of medical inflation
If not case-by-case, how are short term insurance policies reserved for? Explain it
1 Statistical estimation 2 Good for homogeneous claims 3 Volume large 4 Experience stable 5 Split policies into homogenous cohorts 6 Split may be by type/source/location 7 Fit statistical distribution to past claims experience to estimate claims incurred from earned premium
How might sensitivity analysis be used in assumptions setting/reserve calcs?
1 Find MAD's for prudent estimates of future experience Assess need for an extent of.. 2 Additional risk margins 3 Global reserves 4 Cap req ..to cover potential adverse deviation
How do reserves interplay with solvency requirements?
1 It’s normal a company is required to maintain minimum level of solvency capital by supervisors
2 This is an additional level of protection for policyholders above reserves
3 So reserves and solvency capital adequacy should be considered in tandem not independantly
4 The balance between the 2 vaires between countries
5 Some may have reserves on a realistic basis (low prudence) but large SCR’s or vice verca
