| PremiumDiscountCode | `Public Property PremiumDiscountCode() As String` | Discount-band code used to look up the premium-size discount schedule. |
| PremiumRangeLowerLimit | `Public Property PremiumRangeLowerLimit() As Decimal` | Lower premium threshold of the discount band that contains the requested premium amount. |
| PremiumRangeUpperLimit | `Public Property PremiumRangeUpperLimit() As Decimal` | Upper premium threshold of the discount band that contains the requested premium amount. |
| DiscountRate | `Public Property DiscountRate() As Decimal` | Discount percentage applied for this premium-size band. |
| BaseDiscountAmount | `Public Property BaseDiscountAmount() As Decimal` | Fixed base discount amount associated with this premium-size band. |
| ExcludedPremiumAmount | `Public Property ExcludedPremiumAmount() As Decimal` | Premium amount excluded before applying the band discount calculation. |
| Equals | `Public Overloads Shared Function Equals(ByVal objA As Object, ByVal objB As Object) As Boolean` | Compares two objects as premium-size-discount bands using the type-specific equality logic. |
| Equals | `Public Overloads Overrides Function Equals(ByVal inObject As Object) As Boolean` | Treats another object as equal when it is a `clsPremiumSizeDiscount` with the same band code and lower limit. |
| Equals | `Public Overloads Function Equals(ByVal inObject As clsPremiumSizeDiscount) As Boolean` | Treats two discount-band instances as the same row when code and lower premium limit match. |
| GetHashCode | `Public Overrides Function GetHashCode() As Integer` | Hashes `DiscountRate`, the value this type uses as its identity key in keyed collections. |
| ToString | `Public Overrides Function ToString() As String` | Formats the instance as its discount rate. |
| GetPremiumSizeDiscount | `Public Shared Function GetPremiumSizeDiscount(ByVal inDataportal As IDataPortalInfo, ByVal inPremiumDiscountCode As String, ByVal inPremiumSize As Decimal) As clsPremiumSizeDiscount` | Retrieves the a premium-size discount band identified by the key values or effective-date criteria supplied by the caller. |
| Member | `Public Const Retrieve_SQL As String = "Select " & "PREMIUM_DISCOUNT_RANGE.PREMIUM_DISCOUNT_CODE as PremiumDiscountCode, " & "PREMIUM_DISCOUNT_RANGE.LOWER_PREMIUM_RANGE as PremiumRangeLowerLimit, " & "PREMIUM_DISCOUNT_RANGE.UPPER_PREMIUM_RANGE as PremiumRangeUpperLimit, " & "PREMIUM_DISCOUNT_RANGE.DISCOUNT_RATE as DiscountRate, " & "PREMIUM_DISCOUNT_RANGE.BASE_DISCOUNT_AMT as BaseDiscountAmount, " & "PREMIUM_DISCOUNT_RANGE.EXCLUDED_PREMIUM_AMT as ExcludedPremiumAmount" & " From " & "PREMIUM_DISCOUNT_RANGE"` | Base `PREMIUM_DISCOUNT_RANGE` select statement that criteria append range predicates to during retrieval. |
| PremiumDiscountCode | `Public Property PremiumDiscountCode() As String` | Discount schedule code used to select the applicable premium-size band. |
| PremiumAmount | `Public Property PremiumAmount() As Decimal` | Premium amount matched against the row lower and upper premium bounds. |
| New | `Public Sub New(ByVal inDataPortalInfo As IDataPortalInfo)` | Creates an empty BOF object shell that shared factory methods or retrieval logic can populate with a loaded row. |
| New | `Public Sub New(ByVal inDataPortalInfo As IDataPortalInfo, ByVal inPremiumDiscountCode As String, ByVal inPremiumAmount As Decimal)` | Creates a criteria-backed instance seeded with `inPremiumDiscountCode`, `inPremiumAmount` so the next retrieval runs in the caller's requested context. |
## Inherited public members
| Member | Signature | Purpose | Origin |
| --- | --- | --- | --- |
| Rules | `Property Rules As clsRulesManager` | Owns the BOF rules manager used to evaluate registered validation logic.† | `SAIF.Framework.Core` — `clsBusinessBase` |
| BeginEdit | `Sub BeginEdit()` | Opens an n-level edit session for the business object.† | `SAIF.Framework.Core` — `clsBusinessBase` |
| CancelEdit | `Sub CancelEdit()` | Rolls back the active edit scope.† | `SAIF.Framework.Core` — `clsBusinessBase` |
| ApplyEdit | `Sub ApplyEdit()` | Commits the active edit scope.† | `SAIF.Framework.Core` — `clsBusinessBase` |
| Error | `ReadOnly Property Error As String` | Surfaces aggregate broken-rule text through `IDataErrorInfo`.† | `SAIF.Framework.Core` — `clsBusinessBase` |
## Behavioral notes
- The object layers convenience logic over the loaded row, such as equality keys, related-row resolution, or validation helpers.
## Constraints and usage notes
- Retrieve the row with the same keys and effective context that the caller will use later, because helper members derive additional data from that loaded state.
