"The huge literature in risk theory has been carefully selected and supplemented by personal contributions of the author, many of which appear here for the first time. The result is a systematic and very readable book, which takes into account the most recent developments of the field. It will be of great interest to the actuary as well as to the statistician who wants to become familiar with the subject." Math. Reviews Vol. 43

"..., the book (and its author) had enormous impact on the development of risk theory. It was the first self-contained monograph on risk theory providing a rigorous probabilistic foundation. ...[and]... made an important contribution to the successful development of risk theory. This success has made the book a classic." Zentralblatt MATH, 1996
