The determination of rates and the involvement in preparation of rate filings for submission to state insurance departments is one of the key functions that property/casualty actuaries perform. At the current time, a number of standards provide guidance to actuaries on various ratemaking issues and the determination of estimated future costs for property/casualty insurance, including the following:

  1. ASOP No. 12, Risk Classification (for All Practice Areas)
  2. ASOP No. 13, Trending Procedures in Property/Casualty Insurance
  3. ASOP No. 23, Data Quality
  4. ASOP No. 25, Credibility Procedures
  5. ASOP No. 29, Expense Provisions in Property/Casualty Insurance Ratemaking
  6. ASOP No. 30, Treatment of Profit and Contingency Provisions and the Cost of Capital in Property/Casualty Insurance Ratemaking
  7. ASOP No. 38, Using Models Outside the Actuary’s Area of Expertise (Property and Casualty)
  8. ASOP No. 39, Treatment of Catastrophe Losses in Property/Casualty Insurance Ratemaking
  9. ASOP No. 53, Estimating Future Costs for Prospective Property/Casualty Risk Transfer and Risk Retention

The ASOPs above, and in particular ASOP No. 53, provide guidance to actuaries on all aspects of the actuarial estimation of future costs, which are often used in supporting the analysis contained in rate filings. There is currently no ASOP providing guidance to actuaries on the actuarial aspects of the selection of final rates and property/casualty rate filings. Before developing such an ASOP, the Rate Filings Task Force has several preliminary questions, the answers to which will sharpen the scope of the proposed ASOP and provide direction for the drafting effort. The intent of the proposed ASOP would be to build upon the already existing ASOPs, supplementing the guidance provided by the current set of ASOPs.

Scope and Possible Content of Proposed ASOP

The proposed ASOP would address the actuarial aspects of property/casualty rate filings submitted to state insurance departments. The proposed standard would provide guidance to actuaries regarding the actuarial aspects of a rate filing for the filing actuary, the regulatory actuary, and the reviewing actuary. The ASB requests your assistance and guidance in determining which components are actuarial in nature.

Request for Input

The ASB is interested in the views of actuaries, other parties involved in the determination of rates and the preparation and/or review of rate filings submitted to state insurance departments, and any others that have opinions on the matter of the actuarial aspects of the insurance rate filing process.

While the ASB is interested in receiving input from all interested parties, we are particularly interested in your views if you are working in a regulatory capacity or as a consultant to regulators.

In particular, we would like to hear views related to the following:

1. What are the existing or current actuarial responsibilities in determining the final proposed rates?

2. What are the existing or current actuarial responsibilities in the development of a rate filing?

3. Are there aspects of rate filings that you consider actuarial in nature? What aspects do you consider not actuarial in nature?

4. What aspects of a rate filing frequently cause issues during regulatory review?

a. Do these issues cover actuarial content that should adhere to ASOP guidance?

b. If so, what makes these issues actuarial content in your opinion?

c. If not considered as actuarial content, why not?

5. Given that many rate filings contain the results of large computer modeling, does the proposed ASOP on Modeling sufficiently address your concerns with regard to rate filings?

6. What actuarial aspects need further guidance to actuaries in the rate determination process beyond the guidance already contained in existing ASOPs?

7. What actuarial aspects need further guidance to actuaries in the rate filing process beyond the guidance already contained in existing ASOPs?

8. Is guidance to actuaries needed for all rate filings?

a. All lines of insurance?

b. All types of rate regulation laws (prior approval, file and use, use and file, etc.)?

c. If not needed for all filings, which specific filings either limited to specific lines of insurance, rate regulatory laws, or other conditions would trigger activation of the ASOP?

9. Should the scope of this standard be confined to filings that require an actuarial certification?

To help us better understand your responses, please include information about your position and role in the rate filing process. For example, it would be helpful to include the following information in your response:

A. I am (include all that apply)

• An actuary for an insurance company

• An actuary for a rating bureau / rate advisory organization

• A regulator or a consultant to a regulator
