# iPolicyPeriodRatingPlan

Interface defining the policy period rating plan contract; specifies the ER Mod, SARAP factor, claim rating factor, type code, and date properties required of policy period rating plan implementors. Implemented by `clsPolicyPeriodRatingPlan`.*

## Purpose
- Defines the typed contract for policy period rating plan data, decoupling rating plan consumers from the concrete persistence type.*
- Consumed by premium calculation and reporting workflows that need rating plan attributes without coupling to `clsPolicyPeriodRatingPlan` directly.*

## Context
- Namespace: `SAIF.Business.Policy.Premium`
- Assembly/package: `SAIF.Business.Policy.Premium`
