A review of 19 filings shows the past two weeks were dominated by Commercial Auto activity in Florida, where all Berkley‐affiliated companies filed to adopt a +15.5 % ISO loss-cost revision. At the same time, two Great American subsidiaries asked to delay the same ISO update. Personal Auto filings were lighter – Allstate filed an 8.7% increase in Tennessee and American Family filed a 0.9% increase in Florida.
