Steps to Establish Experience Assumptions
- Identify the assumption required

- Analyze experience and trends
- Review and adjust assumptions and reasonableness, consistency, and appropriateness
- Document assumptions
- Monitor experience and updated assumptions

Expected Mortality: Fully Underwritten
Key principles in deciding the complexity of the assumption structure
- Differences in experiences assumptions should reflect differences in experience
- The definition of a class should be easily understood
- The number of classes should be practical and cost effective
Experience Assumptions for Ind Life and Ann (LP-107-07)
Experience Classes
When calculating an assumption, experience should be divided into experience classes
Experience classes will consist of contracts that:
- Are of similar type
- Have similar structure
- Are issued over a continuous period of time
- Have similar marketing objectives

Analyzing Experience and Trends
USEERRs
- Use actual or similar experience
- Sensitivity test the assumptions
- Evaluate credibility of data
- Evaluate quality of data
- Reflect trends in experience as appropriate
- Reflect internal and external factors

a. LaTeX needed
b. LaTeX needed - Common experience
a. Age/duration

Analyzing Mortality Experience
CRAM
- Credibility
- Risk covered
- Adjusting mortality for special situations
a. Multiple life policies
b. Substandard mortality
c. Term conversions
d. Anti-selection
e. Blending mortality tables
f. Adjusting similar experience - Mortality studies

Credibility of Mortality Assumption
- Credibility is measured through a confidence interval (CI)
- 95% CI = m +/- 1.96 * s
a. m = n * q
b. s^2 = n * p * q - Enhancing credibility
a. Use multiple years of exposures
b. Group ages into 5 or 10 age groups
c. Could do an actual to expected analysis using an industry study - Expected value and variance for a group of policies – by counts
LaTeX needed
- Expected value and variance for a group of policies – by amounts
LaTeX needed

Risks Covered in a Mortality Study
Only include standard risks in mortality study
Exclude the following:
- Policies not subject to normal underwriting
- Substandard policies
- Extended term or reduced paid up insurance
- Multiple life policies
Experience Assumptions for Ind Life and Ann (LP-107-07)
Mortality Studies
- Anniversary-to-anniversary or calendar year studies
- 5 years is the typical study period
- Amounts vs. Counts – use by amounts to reflect financial impact
- Mortality rate for a cell = Total Claims / Total Exposure
- Exact exposures
LaTeX needed
- Balducci assumption
LaTeX needed
- Common to make simplifying assumption that lives lapse at the end of the year and deaths occur in the middle of the year
Experience Assumptions for Ind Life and Ann (LP-107-07)
Term Conversion
- Term conversions usually result in higher mortality
- Ways to handle term conversions
a. Include in regular mortality studies – all permanent policyholders share in the extra cost
b. Include a charge in the term pricing - Formula for the cost of extra mortality s years after conversion
LaTex needed
Experience Assumptions for Ind Life and Ann (LP-107-07)
Conservations of Deaths
- Reflect anti-selection or new risk class in mortality experience
- The weighted average mortality of two populations balances back to the standard assumption
- One-year formula
LaTeX needed
- Multi-year formula
LaTeX needed

Adjust Similar Experience to Reflect:
MR CUD (is chewing)
- Market - lower mortality for affluent markets
- Reinsurance quotes
- Company’s underwriting standards
- Underwriting classes and requirements
- Distribution channels
Experience Assumptions for Ind Life and Ann (LP-107-07)
Structure of Lapse Assumptions
- Common experience classes
a. Duration
b. Issue age
c. Frequency of premium
d. Policy size
e. Plan type (term vs. UL)
f. Marketing method
g. Target market - Shock lapse - may be applicable at end of surrender charge period
- Dynamic lapse - may be applicable for investment products
Experience Assumptions for Ind Life and Ann (LP-107-07)
Analyzing Lapse Experience
- Credibility is less of a concern for lapse rates when compared to mortality rates
- Lapse study – Almost identical to performing a mortality study
- Include these lapses in the lapse study:
a. Termination without value due to non-payment of premium
b. Cash surrenders
c. Transfers to extended term or reduced paid up - The lapse study may or may not include the following:
a. Term conversions
b. Partial withdrawals
c. Premium persistency
d. Termination because policy loan exceeds cash value
Experience Assumptions for Ind Life and Ann (LP-107-07)
Structure of Interest Rate Assumptions
- Deterministic, multiple deterministic scenarios, or stochastic scenarios
- Portfolio rates or New money rates
- Net Rate = Gross Rate - Spread
- Investment returns may be based on book value or market value
- Policy loans can be treated as an asset cash flow or a liability
Experience Assumptions for Ind Life and Ann (LP-107-07)
Analyzing Investment Experience
- Book value basis: I = 2I / (A + B - I)
- Market value basis: r = (B - A - C) / (A + C/2)
- Mutual fund returns: r = (B - A) / A
- Tim weighted return = LaTeX needed
- Dollar weighted return (R)
LaTeX needed
Experience Assumptions for Ind Life and Ann (LP-107-07)
Analyzing Expense Experience
- Expense assumption = Expenses / Units
- Units could be: Premium, policies, per 1000 of insurance, other
- Number of units in an expense study
a. If expenses are charged at the beginning of the year
Units = (A + B + N) / 2
b. If expenses are charged at the middle of the year:
Units = (A + B) / 2
- Expense allocation - indirect expenses need to be allocated down to the product level
Experience Assumptions for Ind Life and Ann (LP-107-07)
Projecting Expenses
- Historical expense trends
- Expected inflation rates
- Expected volume of business (economies of scale)
- Impact of any expected changes in the company’s business
- Productivity Gains
Experience Assumptions for Ind Life and Ann (LP-107-07)
Source of Data for Mortality Assumption
- Company Experience
- Inter-company experience

- Private organizations, reinsurers, or actuarial organizations
Expected Mortality: Fully Underwritten
Criteria for a Good Credibility Method
- The method is practical to apply
- There is no double counting or omission
- All of the relevant information is used
- Results are reasonable in extreme cases
- The sub-category A/E ratios are reasonable when compared to company and industry experience
Expected Mortality: Fully Underwritten
Limited Fluctuation Credibility (LFCT)
- LFCT provides a method for establishing full and partial credibility
- Formula and notation
LaTeX needed - Formula for Z
LaTex needed
Expected Mortality: Fully Underwritten
Steps for the LFCT Normalized Method
- Calculate mortality ratios and credibility factors for the entire company and for each sub-category
- Calculate total company blended experience mortality ratio and expected claims using the credibility factor
- Calculate the sub-category blended experience mortality ratio and expected claims using sub-category credibility factors
- Normalize by multiplying each sub-category’s results by the ratio of the total expected claims in step 2 to the sum of expected claims in step 3.
