Deductible and Excess Coverage, Liability and Property Damage Lines, Other Than Automobile [Discussion]

As in the paper presented two years ago on Product Liability Insurance, Mr. Cahill has given us in this paper on Deductible and Excess Coverages for Liability lines other than automobile a valuable and needed contribution to the actuarial science set forth in the proceedings of our Society. In the past we have heard several papers which touched this subject, but touched it no more than tangentially, and only from the point of view of theory. This paper for the first time gives us a summary and an enlightening discussion of actual practice in the writing of these coverages.
