Advisory rating classification and territory structure

ERC is documented as the exact digital representation of ISO Commercial Lines Manual instructions with automated rule updates, while Verisk documents ISO pricing estimates by class and territory. Together these establish that ERC supplies the rule content needed to determine the applicable commercial-lines classification and territory for a selected jurisdiction.

Verisk documents that ISO rating rules use its data, loss costs, and coverage forms to support classification and pricing, and its loss-cost methodology identifies state, territory, class, coverage, limit, and deductible as pricing dimensions. This is Strong current advisory rule and dimension evidence for licensed lines; preserve line, jurisdiction, selected rule/content, and retrieval date, and do not infer an undocumented universal code scheme or edition field.

AAIS Member content provides current manuals and rating information under state-by-state affiliations, and verified programme fact sheets explicitly document detailed rating classifications and classification rating categories. This is Supplemental classification evidence only; the checked materials do not document a complete territory code/description and assignment contract, so preserve programme, jurisdiction, manual, and retrieval context.

S2M Product Models provide forms, endorsements, and rules, while Rating & Data Tables provide territorial definitions from multistate and state manual pages. This is Supplemental evidence for the territory/rule portion only; the public contract does not establish class-assignment codes, a complete classification scheme, edition, or effective date, so preserve the delivered artifact and retrieval date and do not present it as complete classification evidence.
