iPeriodRatingInfo

iPeriodRatingInfo is the declaration-only contract that defines the minimal set of rating attributes a policy period must expose to participate in rating comparisons; it is the base of iPolicyPeriodBase and the type the PeriodRatingInfoExtensions module operates on. Implementations live outside this library (e.g. in SAIF.Business.View.Policy), making this interface part of the library's primary integration boundary with higher layers.*

Purpose

• Standardize the rating-relevant attributes (dates, extension flags, rate tier, market type) that any policy-period-like type must expose for rating comparisons (BR-POL-018).
• Provide a base IEquatable(Of iPeriodRatingInfo) contract so implementers get a uniform equality shape, with the actual comparison logic supplied by PeriodRatingInfoExtensions.BaseEquals.

Context

• Namespace: SAIF.Business.Policy
• Assembly/package: SAIF.Business.Policy (PolicyCommon)

Public members

Member	Signature	Purpose
AnniversaryRatingDate	ReadOnly Property AnniversaryRatingDate As Date	Anniversary rating date used in rating-period equality (BR-POL-018).
RatingEffectiveDate	ReadOnly Property RatingEffectiveDate As Date	Rating effective date used in rating-period equality (BR-POL-018).
IsARDExtended	ReadOnly Property IsARDExtended As Boolean	Indicates whether the anniversary rating date has been extended; part of the equality comparison (BR-POL-018).
IsREDExtended	ReadOnly Property IsREDExtended As Boolean	Indicates whether the rating effective date has been extended; part of the equality comparison (BR-POL-018).
EffectiveDate	ReadOnly Property EffectiveDate As Date	Period effective date used in rating-period equality (BR-POL-018).
ExpirationDate	ReadOnly Property ExpirationDate As Date	Period expiration date used in rating-period equality (BR-POL-018).
RateTierCode	ReadOnly Property RateTierCode As String	Rate tier code used in rating-period equality (BR-POL-018).
MarketType	ReadOnly Property MarketType As Enums.MarketTypes	Market type used by IsVoluntary/IsAssignedRisk and in rating-period equality (BR-POL-015, BR-POL-018).
GetHashCode()	Function GetHashCode() As Integer	Contract hook for a hash consistent with BaseGetHashCode.

Behavioral notes

• This interface declares no implementation; all comparison logic lives in the PeriodRatingInfoExtensions module operating on these properties.
• No in-repo implementer of iPeriodRatingInfo directly was found; iPolicyPeriodBase extends it and is implemented outside this library.*

Constraints and usage notes

• Implementers are responsible for supplying stable values for all eight attributes so that BaseEquals/BaseGetHashCode behave consistently (BR-POL-018).

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts.
