In times of profound demographic change, private life insurance is steadily gaining importance for the financial security of individuals in our society. A solid understanding of how private life insurance works and its products is therefore not only significant for the traditional life insurance actuary in the actuarial departments of insurance companies but also for numerous primarily business-oriented activities in the financial services sector and beyond. This formed the objective of this book. The authors address readers from universities, academies, and professional practice who are seeking a quick and reliable introduction to the classical mathematics of life insurance. Furthermore, they aim to encourage those interested to further engage with the many branches of this topic.
