Learning outcomes

The course will provide students with the mathematical and logical skills needed to address the main actuarial problems in life and non-life insurance, with particular reference to the determination of premiums and reserves as well as the evaluation of profitability and riskiness of insurance portfolios. The course consists of two modules, dedicated to Life and non-Life insurance. During the semester some seminars on selected topics, held by industry experts, will be offered.

Syllabus

Dual teaching (in presence and remotely)

Life Module
1. Basic Knowledge
• Mutuality and Solidarity

• Actuarial values
• Mathematical reserve
• Single premiums, periodic premiums
• Risk premiums and saving premiums
• Surrender values and paid-up values
3. Finance in life insurance

Assessment methods and criteria

The exam consists of a two-hour written test, equally divided between the Non-Life and Life modules.
The structure of the test is as follows:
- two numerical exercises, applying models learnt in the course
- some multiple choice questions and some open questions, aimed at verifying the ownership of language and the ability to systematically link the knowledge gained
During the test the use of the calculator will be allowed, but not of personal notes or other teaching material.

The written essay is taken in a teaching room or (under a student's request) remotely
