A Uniform Statistical Plan and Integrated Rate Filing Procedure for Private Passenger Automobile Insurance [Discussion]

Mr. DuRose has published a very interesting paper illustrating the dilemma confronting a rate analyst when reviewing automobile liability rate filings made with an insurance department. Using Wisconsin as an example, Mr. DuRose pointed out that in 1957 two hundred and five companies either filed automobile liability rate revisions, had such filings made on their behalf by rating bureaus, or continued to write under filings made prior to 1957. If each company had made only one filing in 1957 or had a filing made on its behalf by a rating bureau, the Department Rate Analyst would have had to review ninety-eight separate and distinct filings of automobile liability rates for private passenger cars and would have had to determine if such filings met the requirements of the rating law that rates “not be excessive, inadequate or unfairly discriminatory.”
