What a company-level view adds
A single filing tells you very little on its own: it applies to one line, one programme and one year. Looking at every filing a company made in the same period shows whether the large number was an isolated request or part of a pattern across its whole book.
Insurance Services Office, Inc. files in 2 lines here: Auto Liab/Phys Damage, Homeowners Multi-Peril. A request in one line does not carry over to another, which is why the table keeps them separate rather than averaging them into a single figure.
How to read the numbers
Each percentage applies to that filing's own rate level. Adding them together, or averaging across lines, produces a number that does not correspond to anything a policyholder pays. The median above is shown for orientation only.
A request is also not a decision. Regulators grant, cut or reject, and the outcome lives in the filing documents rather than in the index this site collects.
