AI and machine learning are increasingly used to process claims faster, enhance damage assessment, and reduce fraud, which directly improves reserve accuracy.
Since rates are set before losses are fully known, actuaries must from historical data using the same reserving techniques (chain-ladder, B-F). Then they trend those losses to the future policy period to account for inflation, frequency changes, and severity changes.
Claims that have been reported but where the initial case reserve is expected to grow over time (bulk or development reserves). 4. Fundamental Loss Reserving Methods AI and machine learning are increasingly used to

Modern insurers leverage vast datasets, including telematics for auto insurance and IoT devices for property insurance, allowing for highly personalized, risk-based pricing rather than relying solely on historical averages.
At its simplest, the pure premium (the portion needed to pay claims and claims-related expenses) is: At its simplest, the pure premium (the portion
Costs associated with investigating and settling claims (e.g., legal fees, adjuster costs).
A good actuarial practice uses from reserving to inform loss trend in ratemaking. For example, if the chain ladder shows medical claim costs are inflating at 7% per year, the pricing actuary builds a 7% annual trend factor into future rates.
