Steps
Identify the applicable ISO program, line of business, and edition date for the risk being rated
Retrieve ISO filed loss costs and rating factors for the applicable class codes and coverage forms from your carrier's ISO license or Verisk's electronic rating content delivery
Apply ISO loss costs to the insured's exposure base (payroll, sales, area, or units as applicable to the line) to compute a base manual premium
Apply ISO rating algorithms including increased limits factors, deductible credits, classification relativities, and territory factors as specified in the ISO circular
Apply any carrier-specific modification, schedule rating, or experience rating factors filed on top of the ISO base
Document the ISO edition date, circular references, and rating steps in the quote file for audit and regulatory examination purposes
Known gotchas
ISO loss costs are advisory rates; carriers must file their own loss cost multipliers (LCMs) with each state DOI to convert ISO loss costs into final rates — using ISO loss costs directly as rates without an LCM filing is non-compliant
ISO regularly updates loss costs and rating algorithms through circulars with specific state and effective date applicability; using a superseded edition date produces incorrect rates
Access to ISO rating content requires a valid Verisk/ISO license for each line of business and jurisdiction; unlicensed use of ISO content is a contract violation
