Group and Health Specialty Flashcards
Types of antiselection
- External - occurs as the person is first becoming insured. Those with expensive health conditions will seek insurance.
- Internal - occurs while the person is insured
- Durational - occurs as people make decisions about whether to end coverage. Higher cost insureds tend to keep their coverage in force longer.
What is the buy-down effect?
Buy-down effect = upon receiving a rate increase, some policyholders switch to lower cost plans, so the actual premium increase will be less than expected.
What is premium leakage?
Premium leakage = unhealthy individuals are less likely to buy down their benefits. So the claim cost reduction is less than the premium reduction and not enough premium is collected.
Mechanisms for controlling external antiselection:
- Individual underwriting before issue.
- Pre-existing condition limitations.
- Requiring an enrollment mechanism that doesn’t permit anti selection, such as requiring a minimum participation percentage for associates.
Tools used in underwriting process
- Individual application- includes medical history, financial information, and a release to obtain information from third parties
- Attending physician statement- insurer may choose to request APS from any physician listed in the application
- Commercial databases (e.g. MIB)- used to check information provided in the application
- Internal data - such as prior applications and claim databases
- Telephone interviews - can replace the need for requesting third party information, thereby speeding up underwriting process
- Inspection reports - any information obtained through direct contact with the applicant or other related to the applicant
- Lab testing - may detect tobacco, illegal drugs, or the presence of some medical conditions
- Medical exams - due to high costs, rarely used in underwriting for medical coverages
- Tax returns - often the best source of financial information
- Pre-existing condition provisions - used to protect against antiselection
Actions available to the underwriter
- Offer full coverage with no restrictions
- Decline coverage
- Offer coverage at a higher premium rate, either temporary or permanent
- Offer a standard policy with an exclusion rider for a specific body system or condition
- Offer a different policy than the one applied for, such as one in a substandard risk pool
- Offer a different benefit plan than the one applied for, e.g. longer elimination period or shorter benefit period
Criteria for selecting claims to investigate
- timing - do not investigate claims beyond the time limit for rescinding a contract
- conditions - certain conditions can be ruled out as being a pre-existing condition
- size - don’t investigate a claim if the cost of investigation exceeds the cost of the claim
- sentinel conditions or procedures - some conditions are related to others that lend themselves to antiselection (e.g. HIV)
Situations when the CAST model doesn’t work well
- In the first 3-4 durations, when impact of underwriting wear off overwhelms the CAST effects. The solution is to apply additional underwriting selection factors.
- In later durations, where only a fraction of the original population remains. The solution is to choose a higher value of k2 and recalibrate the model.
- At all durations, when a rate spiral is severe and volatile.
Shock Lapse formula
Shock Lapse = [Rate increase - Trend] / [(Rate Increase - Trend) + (1 + Trend) / EF]
Uses of health insurance financial models
Hint: Please read my story featuring actuaries
- Pricing - financial and sales models are used to determine premium
- Reserve calculations and reserve basis evaluation - some reserves such as gross premium reserves are calculated by forecasting models
- Monitoring of results - to validate assumptions, to warn of deviations from expected values, and for resource planning
- Solvency testing - may indicate a need for gross premium reserves
- Financial forecasting - corporations forecast results for various reasons
- Actuarial appraisals - these are studies of the value of a block of business, typically used when transferring ownership
Characteristics of a good model
Hint: ASSER
- Reliable accuracy - must be good at predicting the future. Must also be robust
- Suitability for use - model should produce results it was designed for, without adding unnecessary complications
- Appropriate precision - this relates to how many decimal places should be kept in the values
- Sensibility - the model should reflect a logical construction of what is being modeled
- Effectively communicated - this includes communicating everything necessary to understand and use the model’s results
Steps in building a forecast model
Hint: Sing in an eloquent voice. Don’t cough.
- Choose basic structure. Tools can include spreadsheets, databases, and sequential programs. Model types include asset share models and reserve development models.
- Choose information to be carried. the information needed will depend on the purpose of the model.
- Choose assumptions and building a prototype projection. Starting values and assumptions must be built into the model. A prototype cell is defined, and then projected to the end of the forecast period.
- Extending the prototype - after the prototype cell is built, the model must be extended to other cells which represent the different subsets of the business being modeled.
- Validate the model
- Document the model - allows model to be evaluated by professionals, and makes it easier to modify
- Design output and communicate results - output can be useless unless it is in the context of the question being asked
Model validation methods
- Starting values are compared to actual values for that year
- Year to year changes in the model are compared to actual past historical results
- Model results are checked for reasonableness by people familiar with the business
- Stress testing - analyze how the modeled results behave when some of the underlying assumptions are changed
Assumptions needed for forecasting
HINT: let me call every pretty man
- Lapse assumptions
- Mortality - some models combine mortality and lapse
- Claim costs - best to use actual experience. Trend assumptions are needed to predict future claim costs.
- Expense assumptions - expenses are usually expressed on a per unit basis.
- Profit - ROI, ROE, or % of premium
- Model office assumptions - define he proportion of the block of business represented by each model cell
Bases used as expected amounts for AtoE analysis
HINT: only parrots can talk
- original pricing assumptions - management expectations are often based on this
- profit targets - bottom line that most senior management is interested in
- current pricing - useful for inflation sensitive products
- tabular - for DI and LTC, companies with large amounts of data may develop their own internal tables for comparisons
Types of reserves in disability income insurance
Active life - exists for policies priced on a level-premium basis. Consists of the excess premiums charged in early years to cover the premium shortfall in later years
Disabled life reserve - established to cover each disability claim and its projected length
Factors that stimulate product development for disability income
- Responding to competition - marketplace is product sensitive, so must react to competitors’ product changes
- Consumer demands - as the consumer has become more aware of the need for DI, this product has evolved
- Claims experience - must be monitored on an ongoing basis
- Governmental influence - regulatory and tax changes can also impact disability income insurance
Areas that participate in the product development process
- Sales and marketing - closest to consumer, which results in product ideas competitive info
- Actuarial - determines pricing and safeguards for new products
- Underwriting - determines if new UW approach is necessary
- Claims - determine what new risks and factors it will face in administering claims
- Data processing and systems - new products may require substantial modification to existing systems
- Legal - able alternative approaches to avoid problems with state approval
- Investments - investment returns on new products
Types of disability income claim experience studies
- Actual to expected morbidity - most preferable, but often not enough data
a. rate of disability - # disabled lives per 1000 exposed
b. rate of recovery - # of disabled lives that recover, per 1000 disabled lives - Loss ratios - most studies based on this
a. cash ratio - claims dollars paid out / earned premium
b. incurred claims ratio (preferred) = (claims + active life reserve + claims reserve)/ earned premium
Parameters to consider in a disability income claims or persistency study
Hint: Abis is deep gap. Oo
- Occupation class
- Occupation
- Policy form
- Extra benefits
- Age
- Duration
- Elimination period
- Benefit period
- Indemnity (benefit amount)
- Income
- Geography
- Agent and agency
- Sex
- Mode of premium payment
- Smoking status
- Combinations of above parameters
Considerations in establishing morbidity assumptions for LTC
Hint: If you drink too much RUM, consume too much DIRT, listen to too much RAP like MM, or get the CLAP, you might end up in long term care. Consider that.
- Data sources - insured data is best, but can use population data adjusted for bias and other issues
- Integration of coverages
- Reinstatements
- Transfers
- Coordination with other coverage such as Medicare
- Pre-existing requirement - not going to save much b/c of heavy UW
- Level of care - daily costs vary by type of care
- Area - affects utilization and charges
- Policy options and benefit triggers - richer plans lead to more adverse selection
- Age/ gender - older = more expensive. female = more expensive.
- Marital status
- Morbidity improvement - debateable that population experience improving over time
- UW - strongly impacts experience in early durations
- Marketing - broker and agents
- Reinsurance - arrangements include coinsurance, modified coinsurance, yearly renewable term
- Regulatory considerations - actuary must certify that rates are sustainable under moderately adverse experience
Considerations in pricing LTC
Hint: SMILE MPL
- Morbidity
- Investment earnings
- Expenses excluding profit
- Voluntary lapses
- Mortality - 1994 GAM table is used in NAIC model, but many actuaries feel rates in this table are too high
- Surplus strain - reserves have significant impact on pricing due to conservatism required and long duration of policies
- Profit - takes 7-10 years to emerge
- Loss ratio requirements - most states require 60%
Loss ratio formulas for LTC
In order of lowest LR to highest LR:
- PV of paid claims / collected premium
- PV of discounted incurred claims / earned premium
a. this is the approach required by most states - PV of undiscounted incurred claims divided by earned premiums
a. recognizes investment income on claim reserve - PV of discounted incurred claims + PV of change in policy reserve divided by PV earned premium
- PV of undiscounted incurred claims + PV of change in policy reserve divided by PV of earned premiums
Medicare supplement pricing assumptions
Hint: Mama Pisseo
- Morbidity
- Mortality - not significant, frequently combined w/ persistency
- Persistency
- Investment earnings - credited to various types of reserves held
- Selection factors/ underwriting
- Age and sex distribution
- Smoker vs. non-smoker
- Area factors
- Expenses and taxes
- Other considerations - modal factors and policy fees
