| HasCancelledPeriods | `Public ReadOnly Property HasCancelledPeriods() As Boolean` | Derived flag used by workflow logic to detect cancelled periods from the current persisted state.* |
| HasAnyBilledAudits | `Public ReadOnly Property HasAnyBilledAudits() As Boolean` | Derived flag used by workflow logic to detect any billed audits from the current persisted state.* |
| HasNonBilledAudits | `Public ReadOnly Property HasNonBilledAudits() As Boolean` | Derived flag used by workflow logic to detect non billed audits from the current persisted state.* |
| WaiverAmount | `Public ReadOnly Property WaiverAmount() As Decimal` | Meaning of `WaiverAmount` could not be confirmed beyond its compiled implementation context.** |
| WCISAuditCount | `Public ReadOnly Property WCISAuditCount(ByVal inWCISAuditStatus As WCISPayrollStatuses) As Integer` | Number of WCIS audit represented by this audit policy periods.* |

| Add | `Public Shadows Function Add(ByVal inclsAuditPolicyPeriodCollection As clsAuditPolicyPeriod) As Integer` | Adds the supplied business object to the collection and returns its index. |
| Contains | `Public Overloads Function Contains(ByVal inAuditPolicyPeriod As clsAuditPolicyPeriod) As Boolean` | Returns `True` when the collection already contains the supplied business object. |
| Contains | `Public Overloads Function Contains(ByVal inPolicyNumber As Decimal, ByVal inPolicyPeriodEffectiveDate As Date) As Boolean` | Returns `True` when the collection already contains an item with the supplied sequence/key value. |

| ContainsDeleted | `Public Overloads Function ContainsDeleted(ByVal inAuditPolicyPeriod As clsAuditPolicyPeriod) As Boolean` | Returns `True` when the deleted-items list already contains the supplied business object. |
| ContainsDeleted | `Public Overloads Function ContainsDeleted(ByVal inPolicyNumber As Decimal, ByVal inPolicyPeriodEffectiveDate As Date) As Boolean` | Returns `True` when the deleted-items list already contains an item with the supplied sequence/key value. |
| NewAuditPolicyPeriodCollection | `Public Shared Function NewAuditPolicyPeriodCollection(ByVal inDataportal As IDataPortalInfo) As clsAuditPolicyPeriodCollection` | Creates a new unsaved audit policy period collection initialized with the data-portal context needed for validation and save operations. |
| GetAuditPolicyPeriods | `Public Shared Function GetAuditPolicyPeriods(ByVal inDataportal As IDataPortalInfo, ByVal inAuditSequenceNumber As Decimal) As clsAuditPolicyPeriodCollection` | Loads audit policy periods through the BOF data portal using the supplied keys and criteria. |
| GetPolicyPeriodsByPolicyNumber | `Public Shared Function GetPolicyPeriodsByPolicyNumber(ByVal inDataportal As IDataPortalInfo, ByVal inPolicyNumber As Decimal, ByVal inAuditTypeCode As String) As clsAuditPolicyPeriodCollection` | Loads policy periods by policy number through the BOF data portal using the supplied keys and criteria. |
