While the literature on reinsurance is vast, there is currently no comprehensive treatment of the major actuarial and financial aspects of the subject. Many publications deal with specific aspects of the theory without putting them into a proper perspective. Reinsurance: Actuarial and Statistical Aspects treats the topic differently. The theories throughout the book are illustrated with real data from major reinsurance companies from around the world. An extensive bibliography also provides readers with leads for further study.
