What it does
CX 34 11 is part of ISO's 2025 umbrella and excess endorsement filing (CU-2025-OMMFR, 01 26 edition). It adds the "Assault Or Battery" exclusion to the excess form, matching CU 34 68 on the umbrella.
Who needs it
Bars, nightclubs, hotels, apartments, security firms and venues.
How it fits the excess layer
The ISO excess form follows the provisions, exclusions and limitations of the controlling underlying insurance unless the excess form or an endorsement says otherwise. Excess endorsements therefore either add a restriction the underlying does not have, or adjust how the excess layer follows the underlying. Check every CX endorsement on a quote against the underlying policy so the layers line up.
Quoting and selling notes
- Check that the underlying and umbrella layers carry the matching exclusion and explain any gap.
