Whereas premiums are charged once the insurance policy is underwritten, the corresponding amounts paid by the insurer in execution of the contract may take years to materialise. Meanwhile, the insurer has to maintain claims reserves on the liability side of the balance sheet, representing the money which should be held so as to be able to meet with high confidence all future claims arising from policies currently in force and policies written in the past. This can only be done using a model projecting the future cash flows related to claims payments.
What Detralytics can do for you
Detralytics actuaries can assist your teams in developing tailored solutions, ranging from the clever application of the standard techniques (Chain-Ladder and its GLM versions) to the most innovative individual loss reserving models.
Besides aggregate approach, we have also developed expert systems providing case estimates using techniques inherited from data science.
Detralytics actuaries not only master the standard loss reserving techniques but also innovate in individual and semi-individual models. They co-authored reference texts on reserving.
