We will begin reporting our medical professional liability business retention on a percentage of premium retained basis, rather than a percentage of policyholders retained basis, effective with our second quarter 2010 earnings release and 10Q. Consistent with our prior practice of measuring renewal retention by comparing the number of renewed risks against all expiring risks, we will be reporting renewal rentention by comparing expiring premium on renewed risks against total expiring premium. We believe this to be important because the upcoming quarter’s report will, for the first time, combine results from The PICA Group (PICA) with those of our historical medical professional liability business. PICA’s business traditonally has higher policyholder retention and lower premiums per policy. We believe this new retention reporting will facilitate more meaningful comparisons with prior periods and provide greater insight into our results as we write more business that involves policyholders paying widely varying premiums. For example, we believe the non-renewal of a neurosurgeon paying a premium of $100,000 per year should be weighted differently than the loss of a part-time primary care physician paying less than $2,000 per year. Large group policies are another prime example. These policies charge a single premium for a large group of insureds, many of whom may work part-time. The loss of such a policy, while not large in terms of premium, could unduly influence retention measurements that count strictly by number of insured risks—as under our old methodology. To assist investors in preparing for this change in our retention reporting, Exhibit 99.1 in this Current Report on Form 8K, presents prior period data by quarter for 2009, and by year for the preceding four years. |
