“Basic Ratemaking” by Geoff Werner and Claudine Modlin is Released

09/10/2009 —

The Casualty Actuarial Society has released “Basic Ratemaking” as a comprehensive resource for practicing actuaries and actuarial candidates.
Basic Ratemaking by Geoff Werner and Claudine Modlin
Geoff Werner and Claudine Modlin of EMB America, LLC were the principal authors of the text which consolidates numerous syllabus papers on the topic.

The CAS Executive Council first approved “Basic Ratemaking” for use on the 2010 CAS Exam 5 syllabus.

According to the authors, “This text introduces fundamental ratemaking principles supported by consistent terminology and straightforward examples. We focused on quantitative analysis as well as practical considerations in the ratemaking process.”

The authors expressed gratitude to Catherine Taylor for her feedback and guidance and appreciation to the other members of the task force led by Ms. Taylor that worked with the authors to review the drafts.

The CAS Board of Directors initiated the project to provide a consolidated text on the topic of basic ratemaking and another on reserving. In October 2006, the Executive Council created the Task Force on Developing Education Material to engage consultants to prepare an entire set of materials for the ratemaking and reserving portions of current CAS Exams 5 and 6. The Board approved EMB America, LLC for the ratemaking text and KPMG, LLP for the reserving text. The reserving text, “Estimating Unpaid Claims Using Basic Techniques” by Jacqueline Friedland, was released in June 2009.

Both the ratemaking and reserving texts were written to be useful to general insurance (property-casualty) actuaries internationally as a response to the CAS Centennial Goal that the CAS would be “recognized globally as a leading resource in educating casualty actuaries.” For this reason, the CAS is making the publications available free of charge on its Web site.
