Property and casualty net catastrophe loss ratio measures catastrophe losses incurred during the period, including development on prior events and the impact of reinsurance, as a percentage of net premiums earned.
Progressive reported a 2.4 net catastrophe loss ratio companywide for June 2026.
Catastrophe load is only one component of underwriting loss
The catastrophe ratio does not include all ordinary attritional claims or every component of the broader loss ratio.
It isolates catastrophe-related pressure inside the underwriting result.
Reinsurance can change the net outcome
Progressive's definition explicitly includes the effect of reinsurance, if any.
Read it with Property combined ratio and Commercial Lines combined ratio.
