The Book: A Safe Harbor

“Actuarial Considerations…” was compiled to illustrate the wide range of sound actuarial practices

It does not contain all valid approaches, but instead encourages creative solutions

My goal as editor is for regulators to look beyond form to the substance of the rate filing

Two Perspectives

Return-on-Equity

1. Define the product in the corporate environment

2. Use comparative ROE data to allocate surplus and set ROE

3. Adjust as needed for rate filing

Cost of Risk

1. Define risk in a general way and find the market cost of risk

2. Use that cost in product pricing in a corporate environment

3. Adjust as needed for rate filing

Return-on-Equity

Cost of Risk

• Supply and demand for “risk”

The underwriter takes risk premium in consideration for accepting risk transfer

The markets tell us the metric for risk, and the price per unit of risk

We can use that market cost of risk

Risk as a Commodity

Using the Market Cost of Risk

1. Find the cost of risk per unit of exposure

1.1 Determine the risk per unit of exposure

1.2 Apply the market cost per unit of risk

1.3 Determine the premium rate level

2. Optimize the portfolio

2.1 Determine the marginal risk and return to the firm from selling the product (e.g., by using DFA)

2.2 Set volume and price targets to maximize the value of the firm

Communicating to Management

Allocate surplus and select ROE. Then, find the premium rate from DCF calculation.

Find the premium/ price goals that maximize the value of the firm. Then, express these as allocated surplus and

ROE.
