Compute the adjusted rate for a class

ClassRateExtensions.AdjustedRate(Target, inRateTierFactor, inUSLHWFactor, AccidentLimitFactors, OtherFactors) (ClassRateExtensions.vb:39-58)

Field Value
Operation ID OP-001
Trigger Premium rating needs the final rate for a rated class line
Inputs An iAdjustedRateProvider target, a clsRateTierFactor, a clsUSLHWCompFactor, a sequence of accident-limit iAdjustedRateFactor, a sequence of other iAdjustedRateFactor
Outputs Decimal rate rounded to 6 decimal places
Primary components `ClassRateExtensions.AdjustedRate(Target, inRateTierFactor, inUSLHWFactor, AccidentLimitFactors, OtherFactors) (ClassRateExtensions.vb:39-58)`
Entry point Business\SAIF.Business.Policy.Rating\ClassRateExtensions.vb

Steps

  1. Filter OtherFactors, discarding any Nothing entries.
  2. Project each remaining factor to its value by calling factor.Factor(Target) — each factor
  3. Multiply the values into a cumulative factor starting at 1.
  4. Compute the base rate by delegating to BaseRate (OP-002).
  5. Multiply base rate × cumulative factor.
  6. Return Math.Round(Rate, 6) (BR-001).
