## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ID | `Public Property ID() As Decimal` | Caller-managed identifier slot; the built-in retrieval methods do not populate it. |
| AnniversaryRatingDate | `Public Property AnniversaryRatingDate() As Date Implements iPeriodRatingInfo.AnniversaryRatingDate` | Policy-period anniversary rating date returned from the current or legacy policy-period query. |
| RatingEffectiveDate | `Public Property RatingEffectiveDate() As Date Implements iPeriodRatingInfo.RatingEffectiveDate` | Optional rating-effective-date slot carried by the object; the provided constructors and retrieval queries do not set it. |
| IsARDExtended | `Public Property IsARDExtended() As Boolean Implements iPeriodRatingInfo.IsARDExtended` | Indicates whether the policy period's anniversary rating date carries the extension flag. |
| IsREDExtended | `Public Property IsREDExtended() As Boolean Implements iPeriodRatingInfo.IsREDExtended` | Flag slot for rating-effective-date extension; the provided constructors and retrieval queries leave it at the default value unless set later. |
| EffectiveDate | `Public Property EffectiveDate() As Date Implements iPeriodRatingInfo.EffectiveDate` | Policy period effective date for the rating context row. |
| ExpirationDate | `Public Property ExpirationDate() As Date Implements iPeriodRatingInfo.ExpirationDate` | Policy period expiration date for the rating context row. |
| RateTierCode | `Public Property RateTierCode() As String Implements iPeriodRatingInfo.RateTierCode` | Risk type or rate tier code returned with the policy period. |
| MarketType | `Public Property MarketType() As Policy.Enums.MarketTypes Implements iPeriodRatingInfo.MarketType` | Market type enum resolved from `policy.market_type_code`. |
| Equals | `Public Overrides Function Equals(ByVal obj As Object) As Boolean` | Uses the type-specific period-rating comparison when `obj` is another `clsPeriodRatingInfo`; otherwise falls back to base equality. |
| Equals | `Public Overloads Function Equals(ByVal inObject As iPeriodRatingInfo) As Boolean Implements IEquatable(Of iPeriodRatingInfo).Equals ' iPeriodRatingInfo.Equals` | Delegates to the shared `BaseEquals` helper to compare `iPeriodRatingInfo` values. |
| GetHashCode | `Public Overrides Function GetHashCode() As Integer Implements iPeriodRatingInfo.GetHashCode` | Hashes the same identity value this type uses in keyed collections. |
| New | `Public Sub New()` | Creates an empty BOF object shell that shared factory methods or retrieval logic can populate with a loaded row. |
| New | `Public Sub New(ByVal inPeriodRatingInfo As iPeriodRatingInfo)` | Creates a criteria-backed instance seeded with `inPeriodRatingInfo` so the next retrieval runs in the caller's requested context. |
| New | `Public Sub New(ByVal inPolicyPeriod As iPolicyPeriodBase)` | Creates a criteria-backed instance seeded with `inPolicyPeriod` so the next retrieval runs in the caller's requested context. |
| GetPeriodRatingInfo | `Public Shared Function GetPeriodRatingInfo(ByVal inDPI As IDataPortalInfo, ByVal inPolicyNumber As Decimal, ByVal inPolicyPeriodEffectiveDate As Date) As clsPeriodRatingInfo` | Retrieves the rating context for a specific policy and policy-period effective date. |
| GetCurrentPeriodRatingInfo | `Public Shared Function GetCurrentPeriodRatingInfo(ByVal inDPI As IDataPortalInfo, ByVal inPolicyNumber As Decimal) As clsPeriodRatingInfo` | Retrieves the most current policy-period rating context for a policy by selecting the maximum policy-period effective date. |
## Behavioral notes
- Retrieval can come from either the current WCIS policy-period tables or the legacy non-WCIS table.
## Constraints and usage notes
- Callers can request either a specific policy period or the most current one, depending on which shared factory they use.
