A retroactive date determines how far back your coverage reaches for claims that are reported during your policy period. Basically in practice, you can perform work within the date confines, file a claim during the policy period, and then be covered as long as the work related to an incident happens after that retroactive date.
It's policy terms comes in these structures:
- Full prior acts coverage: Covers all past work with no specific cutoff date. This is the most comprehensive option and typically requires continuous coverage.
- Prior acts with a set retroactive date: Covers work performed after a defined date (usually when you first purchased coverage). This is the most common structure.
- New business (no prior acts): Only covers work performed after the policy start date. Any past work is excluded.
- Nose coverage (when switching insurers): Allows you to carry your retroactive date to a new insurer so you don’t lose protection for past work.
