Actuaries use organized historical data tables called to track how claims grow and settle over time. They apply several mathematical models to these triangles:
Ratemaking and loss reserving are two critical components of property and casualty (P&C) insurance. Ratemaking involves setting the premium rates for insurance policies, while loss reserving involves estimating the amount of money that an insurance company needs to set aside to pay for future claims. In this post, we will provide an introduction to these two essential concepts.
Ratemaking is the process of determining the appropriate premium to charge for an insurance policy. The primary goal is to calculate a rate that covers all future claims and expenses while generating a reasonable profit for the insurer. Actuaries use organized historical data tables called to
The evolution of insurance, risk vs. peril, and what makes a risk insurable.
For a new homeowners insurer in Florida, historical hurricane losses might have zero credibility for predicting next year. They would rely on sophisticated catastrophe models instead. In this post, we will provide an introduction
Risk classification must be based on actual actuarial data. Insureds with similar risk profiles must be charged similar rates. The Components of a Rate
The interrelationship between ratemaking and loss reserving is symbiotic. While ratemaking focuses on the future, loss reserving focuses on the past. However, both require the estimation of —the total final cost of claims arising from a specific set of policies. The evolution of insurance, risk vs
It is a fatal error to treat reserving and ratemaking as silos. They are two sides of the same coin.
