Knowledge of risk models and the assessment of risk will be of great importance to actuaries as they apply their skills and expertise today and in the future. Book Risk Modelling in General insurance from principles to practice reflects our intention to present a wide range of statistical and probabilistic topics relevant to actuarial methodology in general insurance. Our aim is to achieve this in a focused and coherent manner, which will appeal to actuarial students and others interested in the topics we cover. We believe that the material is suitable for advanced undergraduates and students taking master's degree courses in actuarial science, and also those taking mathematics and statistics courses with some insurance mathematics content. In addition, students with a strong quantitative mathematical background taking economics and business courses should also find much of interest in the book. Prerequisites for readers to benefit fully from the book include first undergraduate-level courses in calculus, probability and statistics. We do not assume measure theory. Our aim is that readers who master the content will extend their knowledge effectively and will build a firm foundation in the statistical and actuarial concepts and their applications covered. We hope that the approach and content will engage readers and encourage them to develop and extend their critical and comparative skills. Our aim has been to provide opportunities for readers to improve their higher order skills of analysis and synthesis of ideas across topics. A key feature of our approach is the inclusion of a large number of worked examples and extensive sets of exercises, which we think readers will find stimulating. We include three case studies. A risk model is a mathematical technique, system, or method that predicts the risk elements of a business strategy. If done right, a risk model can provide functional data and quantitative estimates that help businesses make financial, strategic and operational decisions. Some models also use qualitative elements, such as relying on subject matter experts to advise. Risk models can provide investment analyses recurring patterns in your operations, and more. Simply put a well designed risk model allows you to input certain values or data and then makes clear and accurate predictions about your business projection. Risk modeling is the systematic and holistic approach to risk management, especially compared to more traditional methods, such as only buying insurance to protect your business.
