Objective 1 Flashcards
Types of antiselection
- External - as person is first becoming insured
- Internal - while the person is insured
a) Buydown effect - upon rate increase, some insureds switch to lower cost plans. Actual premium increase is less than expected
b) Premium leakage - unhealthy individuals less likely to switch. Claim cost reduction not as much as premium reduction - Durational (cumulative) - as people make decisions about whether to lapse
Mechanisms for controlling external antiselection
- Individual underwriting before issue
- Pre-existing condition limitations
- Requiring an enrollment mechanism that doesn’t permit antiselection (i.e., minimum participation percentages for associations)
Tools used in the underwriting process
- Individual application
- Attending physician statement
- Commercial databases (i.e. MIB)
- Internal data (i.e. prior applications and claims)
- Telephone interviews
- Inspection reports
- Lab testing
- Medical exams (expensive - uncommon for medical covg)
- Tax returns
- Pre-existing condition provisions
Actions available to the underwriter
- Offer full coverage w/ no restrictions
- Decline coverage
- Offer coverage at a higher premium (temporary or permanent)
- Offer a standard policy with an exclusion rider
- Offer a different policy than the one applied for (substandard risk pool)
- Offer a different benefit plan than the one applied for (longer elimination period or shorter benefit period)
Criteria for selecting claims to investigate
- Timing - don’t investigate beyond time liming for rescinding
- Conditions - certain conditions can’t be pre-existing
- Size - don’t investigate if cost of investigation > cost of claim
- Sentinel conditions or procedures - related to others that lend selves to antiselection (HIV)
Situations in which the CAST model does not work well
- First 3-4 durations: apply additional underwriting selection factors
- Later durations: choose a higher k2 and recalibrate
- Severe and volatile rate spiral: stronger terms such as
ShockLapse = [RateIncrease - Trend] / [(RateIncrease - Trend) + (1 + Trend) / EF]
EF = elasticity factor; higher for healthy than unhealthy lives
Uses of health insurance financial models
- Pricing
- Reserving
- Monitoring results
- Solvency testing
- Financial forecasting
- Actuarial appraisals
Essential characteristics of a good model
- Reliable accuracy
- Suitability for use
- Appropriate precision
- Sensibility
- Effectively communicated
Steps in building a forecast model
- Choose basic structure
a) Tools: spreadsheets, DB models, sequential programs
b) Model types: asset share, reserve development - Choose info to be carried (depends on purpose)
- Choose assumptions and build prototype projection
a) Starting values and assumptions built in
b) Prototype cell defined, then projected to end of forecast period - Extending the prototype
- Validating the model (separate list)
- Documenting the model
- Designing output / communicating results
Methods for validating forecast models
- Starting values compared directly to actual values for that year
- Year to year changes compared to historical results
- Model results checked for reasonableness by people familiar with the business
- Stress testing
Assumptions needed for forecasting
- Lapse
- Mortality
- Claim costs
- Expense
- Profit
- Model office
Bases used as expected amounts for actual to expected analysis
- Original pricing assumptions
- Profit target
- Current pricing
- Tabular (for DI or LTC)
Types of reserves in disability income insurance
- Active life reserve (for level-premium policies)
2. Disabled life reserve (cover disability claim and its projected length)
Factors that stimulate product development for disability income
- Responding to the competition
- Consumer demands
- Claims experience
- Governmental influences
Areas that participate in the product development process
- Sales and marketing
- Other home office disciplines
a) Actuarial
b) Underwriting
c) Claims - Data processing iand systems
- Legal
- Investments
