At its meeting on March 19, 2008, the Board of Directors approved policy authorizing WorkSafeBC to vary the 2008 and 2009 experience rating of employers identified by WorkSafeBC as having experienced a greater than 10% deterioration in their 2008 experience rating, owing solely to the change in the criteria for the minimum size of rate groups within the Employer Classification System. These employers shall have their 2008 and 2009 experience rating calculated based on comparing the employer’s cost to assessable payroll ratio to the cost to assessable payroll of a simulated rate group that replicates the employer’s 2007 rate group.
