iPeriodRatingInfo

Defines the core rating-period values that rating logic can compare across policy periods, including anniversary and rating dates, extension flags, coverage window, market type, and the rate-tier code that identifies the rating context.

Purpose

• Provide a shared contract for period-level rating inputs.
• Support equality and helper logic through a stable set of rating dates, flags, and classification values.
• Let multiple policy-period shapes participate in the same rating comparison helpers.

Context

• Namespace: SAIF.Business.Policy
• Assembly/package: SAIF.Business.Policy

Member	Signature	Purpose
AnniversaryRatingDate	Property AnniversaryRatingDate() As Date	Supplies the anniversary rate date used by rating logic.
RatingEffectiveDate	Property RatingEffectiveDate() As Date	Supplies the effective date used for rating calculations.
IsARDExtended	Property IsARDExtended() As Boolean	Indicates whether the anniversary rate date was extended beyond its normal value.
IsREDExtended	Property IsREDExtended() As Boolean	Indicates whether the rating effective date was extended beyond its normal value.
EffectiveDate	Property EffectiveDate() As Date	Supplies the policy-period effective date.
ExpirationDate	Property ExpirationDate() As Date	Supplies the policy-period expiration date.
RateTierCode	Property RateTierCode() As String	Supplies the rate-tier identifier used by downstream rating logic.
MarketType	Property MarketType() As Policy.Enums.MarketTypes	Supplies the market classification used by rating comparisons and helpers.
GetHashCode	Function GetHashCode() As Integer	Produces a hash compatible with the value-based equality expectation for rating info objects.

Behavioral notes

• The interface inherits IEquatable(Of iPeriodRatingInfo), and the companion PeriodRatingInfoExtensions module supplies common equality/hash logic for the shared fields.

Constraints and usage notes

• Implementations should keep their equality semantics aligned with BaseEquals and BaseGetHashCode when they rely on the extension helpers.
