B.6. LAE, UW Expenses, and Profit Load Flashcards
Two ways to incorporate ALAE in indications
- Include with losses
2. Analyzed separately (done if ALAE is large as in some commercial lines)
Pure Premium Method Formula
Indicated Premium = (Pure Premium including LAE + Fixed Expense per Exposure) / (1 - V - Q)
Loss Ratio Method Formula
Indicated Change = (Loss and LAE ratio + Fixed Expense Ratio) / (1 - V - Q) - 1
3 methods to incorporate UW expenses in pricing
- All variable expense method
- Premium-based projection method
- Exposure/policy- based projection method
All variable expense method
Treat all UW expenses as variable to premium
Premium-based projection method
Assumes future expense ratios will be consistent with historical expense ratios, but separately calculates fixed an variable expense ratios
Exposure/policy-based projection method
Divide fixed expenses by exposures (or policies) and divide variable expenses by premium
Shortcoming of all variable expense method
Inaccurate if some expenses are truly fixed. Will undercharge risks with lower than average premium since it assumes the expenses are reduced with lower premium
Matching expense categories with data
Other acquisition
General expenses
Commission
Taxes
Other acquisition, general expenses: CW
Commission, taxes: state
3 shortcomings of premium-based method and how they can be addressed
- One time changes can cause inaccurate historical expense ratios. On-level premiums before calculating expense ratio
- Premium and/or expense trends can impact ratios. Trend all premiums and expenses to the projected future level
- Can create inequitable rates across states when CW fixed expenses are allocated by state. Calculate ratios by state
One way to address shortcoming of All Variable Expense Method
Premium discount or expense constant in rating algorithm
2 ways to incorporate non-proportional reinsurance costs into ratemaking
- Restate premiums and losses net of reinsurance
2. Calculate net cost of reinsurance and treat as fixed expense
4 possible enhancements to the exposure/policy based projection method
- Find more scientific way to split expenses into fixed/variable
- Find more equitable way to allocate CW expenses
- Some expenses vary by other characteristics
- Economies of scale in a changing book will lead to increasing/decreasing future average expenses per exposure. Can identify and quantify these impacts
