Berquist-Sherman¶
Case O/S Technique¶
Suppose if the case outstanding changes in the company: - Due to a change in the process
- Select the Severity trend (\(\dfrac{\text{Paid Losses}}{\text{Paid Counts}}\)) by looking at the paid loss triangle
- Downward develop the latest CY severities in the case outstanding triangle using the trend factor and obtain the Adjusted Average Case Outstanding
- Use the claim counts to get back the Reported claims.
