What does SR stand for?

The increases are relatively tame compared to the severity rate increases of six or seven years ago, but they are still outpacing the inflation indexes.

The average severity rate and crash density is also greater at signalized intersections.

Additionally, severity rates tend to decrease when frequency rates go down, thus losses usually decline also.

To be consistent, we assume a constant severity rate of 50% for all the bonds in our example.

This conversion process involved using loan-to-value ratio (LTV) distributions for each type of institution; estimating the extent of PMI use across institutions; applying historical default and loss severity rates by loan-to-value ratio for each type of institution; and reallocating these risk dollars across institutions to account for risk-sharing arrangements between insurers and other institutions.

The top performers in safety are determined following a rigorous multi-stage assessment that includes reviews of Total Recordable Incident Frequency, Lost Time Incident Frequency, and Incident Severity Rate, together with improvements on the previous year's performance.
