Commercial Property

What's New?

Green Upgrades
To help you respond to the growing demand for environmentally friendly rebuilding after a loss, ISO has introduced an endorsement covering green upgrades. We've also filed supplementary rating information. The filings are in effect countrywide. For more information, refer to Circulars LI-CF-2009-210 and LI-CF-2009-211.

2011 Multistate Revision to Commercial Property Coverage Forms and Endorsements
In the fourth quarter of 2011, ISO filed a general multistate revision of commercial property forms and manuals. To help you better serve the needs of your customers, we've made many updates to existing forms and rules (and associated loss costs). We've also introduced many new endorsements, which you can use to provide additional coverages. Examples include business interruption coverage for certain secondary dependent properties and coverage for the increased cost of rebuilding following a disaster. Refer to Circulars LI-CF-2012-001 (forms), LI-CF-2012-002 (rules), and LI-CF-2012-003 (loss costs) for complete details and a copy of each filing. The revision carries a planned effective date of April 1, 2013. Watch this website for a status report as filing activity progresses.

Enhanced Wind Rating Program
ISO has begun to file an enhanced wind rating program, which will provide Basic Group II loss costs for specific eligible buildings in wind-prone states. The program combines building-specific data compiled by ISO personnel with analytics based on ISO statistical data and catastrophe model output from AIR Worldwide. The planned effective date is January 1, 2013. For more information, refer to Circulars LI-CF-2011-136, LI-CF-2012-044, LI-CF-2012-045, LI-CF-2012-048, LI-CF-2012-062, LI-CF-2012-063, and LI-CF-2012-070. Watch this website for a status report as filing activity progresses.

Fire Class Rating Eligibility
ISO has introduced rules that expand eligibility for fire class rating in the District of Columbia and Texas. The changes bring the rules for those two jurisdictions into line with the countrywide program and let you operate in a more uniform manner across the United States. For more information, refer to Circulars LI-CF-2011-118 and LI-CF-2011-139 (D.C. rules), LI-CF-2011-119 (D.C. loss costs), LI-CF-2011-105 (Texas rules) and LI-CF-2011-108 (Texas loss costs).
