Q

W&B of Mod formula are related to and what W&B are

A
  • both W&B are related to credibility and they vary by state and insured size
  • W=weighting value; used to limit weight of actual excess losses
  • B=Ballast value; used to provide stability by limiting impact of any single loss in mod

Q

ELRs and D-ratios

A
  • ELRs represent expected losses per $100 payroll, adjusted for capping applied to actual losses and adjusted to be at historical loss development, trend, and benefit levels corresponding with these levels for actual losses
  • D-ratios represent expected primary percentage of expected losses
  • for each class code in which a risk has payroll, can lookup ELR and D-ratio for that class
  • in general, want to use tables that would apply to policy’s effective date

Q

Application of the mod

A
  • experience mod is applied to sum of manual premium across all classes and locations to obtain standard premium if we ignore the schedule mod
  • since experience mod is applied after manual premium which varies by class, mod differentiates loss potential for risks within a class not between classes

Q

What are the circumstances when entities are combined for Experience Rating?

What is the purpose of such combination?

A

When entities share common majority ownership, they are combined. This prevents the ownership from moving loss experience from one company to another for purposes of manipulating the experience mod.

Q

Assuming that losses increase over time with inflation, should the split point increase, decrease, or stay the same?

A

The split point should increase over time to help maintain the proportions of excess and primary losses. If the split point did not increase with inflation, the D-ratios would decrease, which would cause higher expected excess losses. This would increase mods over time.

Q

procedures to add stability to workers compensation experience rating.

A

Introduce a limit to how much of any single loss enters the experience rating component of ratemaking. Workers compensation have limits for single claimant and multiple claimant accidents.

Give greater weight to actual experience for larger risks - The larger the risk, the more stable their expected losses are. If actual experience for small risks was given the same weight as for large risks, then the mods for small risks would be erratic.

Q

argument against including stability procedures in terrorism insurance ratemaking.

A

Work Comp experience rating and terrorism ratemaking have different goals. WC
experience rating uses past losses to the extent that they are predictive of the future loss to improve individual risk equity. Large losses are capped because to some extent they are bad luck and should not be allowed to swing the mod past a certain point. Terrorism ratemaking is not interested in individual risk equity as much as spreading the cost of terrorism losses across all insureds. Capping losses may improve stability but may lead to inadequacy.

Due to the rarity and catastrophic nature of terrorism losses, it is unlikely that larger risks would have more stable losses than smaller risks.

Q

. An actuarial student learning about the NCCI experience rating plan makes a suggestion to replace all Fatal claims used in the experience rating calculation with an average value of $50,000. Provide 2 responses to the student defending why this change should not be made

A
  • A loss limit already exists in the plan, which limits the impact of large Fatal claims.
  • NCCI studies have shown that excess losses are predictive, so making this change might hurt the predictive value of the plan.
  • This change might lower the safety incentive for insureds that have Fatal claims above the average value.
  • This change would mean that insureds with a Fatal loss in their experience that was lower than the proposed average amount would be charged for losses above their actual experience, which would not be fair.
