Compute the base rate for a class

ClassRateExtensions.BaseRate(Target, inRateTierFactor, inUSLHWFactor, AccidentLimitFactors) (ClassRateExtensions.vb:60-75)

Field Value
Operation ID OP-002
Trigger Called by OP-001, or directly when only the base rate is needed
Inputs iAdjustedRateProvider, rate tier factor, USL&HW factor, accident-limit factors
Outputs Decimal base rate rounded to 4 decimal places using arithmetic (not banker's) rounding
Primary components `ClassRateExtensions.BaseRate(Target, inRateTierFactor, inUSLHWFactor, AccidentLimitFactors) (ClassRateExtensions.vb:60-75)`
Entry point Business\SAIF.Business.Policy.Rating\ClassRateExtensions.vb

Steps

  1. Start a factor list with inRateTierFactor.AdjustedRateFactor(Target) (BR-011).
  2. Add inUSLHWFactor.Factor(Target) (BR-012).
  3. Add each non-Nothing accident-limit factor's value.
  4. Multiply all collected values into a cumulative factor starting at 1.
  5. Return SAIFRound(Target.PureRateFactor * CumulativeFactor, 4) — SAIFRound performs arithmetic
  6. Use the related data-access statements and tables for this operation: SQL-046, USLHW_COMP_FACTOR.

Process flow

The following diagram visualizes this operation's control flow.

Start([Trigger: OP-001 or direct base-rate need]) --> S1[Start factor list: RateTierFactor.AdjustedRateFactor - BR-011]

S1 --> S2[Add USLHWCompFactor.Factor Target - BR-012]

S2 --> S3[Add each non-Nothing accident-limit factor value]

S3 --> S4[Multiply all values into CumulativeFactor starting at 1]

S4 --> Done([Return SAIFRound PureRateFactor x CumulativeFactor, 4])

Failure and edge-case behavior

  • Review the linked business rules and SQL documents for the validation or data-access conditions that can block this operation.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
