In July 2021 I started a 6 months internship at Sompo International, a leading global specialty provider of property and casualty insurance and reinsurance with headquarter in Bermuda. Sompo International Reinsurance operates with experienced underwriting teams worldwide providing a broad range of reinsurance products. I worked within the Reinsurance Actuarial Team in its Zurich Branch and this thesis is a summary of the things I learned along the months I had the opportunity to work within the company. The main purpose of this essay is to analyze the structure and methods that characterize a reinsurance pricing process, to present a client case to have a deeper look into the company’s methodologies and to introduce an alternative method to the company’s standard approach.
