DTCCCACNSD1V03

supl.006.001.03

The DTCCCACNSD1 message extends ISO corporate action cancellation advise (CACN) message with DTCC corporate action elements not covered in the standard message.

Message Construction

Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

Now, we will zero-in one-by-one on each of these building blocks.

Notification building block

Information to be extended as supplementary data to cancellation advice. Customer security identification reference information.

For comparison, see the ISO20022 official specification

CorporateActionNotificationSD1 members

Member name Description Data Type / Multiplicity
PlaceAndName xPath to the element that is being extended. IsoMax350Text - Required 1..1
CustomerInternalSecurityIdentification Internal security identification as provided by the customer for the given security on the security of interest (SOI) import file. IsoMax16Text - Optional 0..1
SecurityOfInterestMatchingSecurity Security identifier that is used to match the customer’s SOI (Security of Interest) to the GCA VS Security Cross Reference. SecurityIdentification15 - Optional 0..1

GeneralInformation building block

Information to be extended as supplementary data to cancellation advice general information. Provides additional information regarding corporate action general information details. For comparison, see the ISO20022 official specification

CorporateActionGeneralInformationSD4 members

Member name Description Data Type / Multiplicity
PlaceAndName xPath to the element that is being extended. IsoMax350Text - Required 1..1
EventType DTCC (The Depository Trust and Clearing Corporation) native corporate action event type name. Used in place for the events that cannot be classified by ISO Code and are marked as OTHR. Can be used in combination with DTCC sub event type (when provided) to identify the event. For an example: a distribution based on recapitalisation event will be presented as event type: OTHR in standard message. DTCC native event type would be Distribution (DIST) and DTCC sub event type would be Recapitalisation. ExtendedEventType1Code - Optional 0..1
SubEventType DTCC (The Depository Trust and Clearing Corporation) corporate action sub event type name further defines the event type. For an example: a cash dividend event eligible for dividend reinvestment at DTC election will be noted as event type: Cash Dividend (DVCA) and DTCC sub event type: DRIP( DTC only). DTCCSubEventType2Code - Optional 0..1

EventsLinkage building block

Information to be extended as events linkage supplementary data to events to cancellation advice. Provides additional information regarding linkage details. For comparison, see the ISO20022 official specification

    LinkAddedDate IsoISODate
    LinkModifiedDate IsoISODate
}
  

CorporateActionCancellationSD1 members

Member name Description Data Type / Multiplicity
PlaceAndName xPath to the element that is being extended. IsoMax350Text - Required 1..1

LinkageType Indicates the reason why two or more events are related. DTCCLinkType1Code - Required 1..1
LinkAddedDate Events can be linked together. This date represents the date on which the link was established. IsoISODate - Required 1..1
LinkModifiedDate Events can be linked together. This date represents the date on which the link was modified. IsoISODate - Optional 0..1

ExternalComments building block

Information to be extended as external comments to cancellation advice. Provides additional information regarding additional comments. For comparison, see the ISO20022 official specification

class CorporateActionCancellationSD2{

ExternalComments Additional textual information regarding the cancelled event. IsoMax8000Text - Optional 0..1

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the DTCCCACNSD1V03 implementation follows a specific implementaiton pattern. First of all, DTCCCACNSD1V03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, DTCCCACNSD1V03Document implements IOuterDocument. Because DTCCCACNSD1V03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type DTCCCACNSD1V03.

classDiagram
    class IOuterRecord
    DTCCCACNSD1V03 --|> IOuterRecord : Implements
    DTCCCACNSD1V03Document --|> IOuterDocument~DTCCCACNSD1V03~ : Implements
    class IOuterDocument~DTCCCACNSD1V03~ {
        DTCCCACNSD1V03 Message
     }
  

Document wrapper for serialization

The only real purpose DTCCCACNSD1V03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:supl.006.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using DTCCCACNSD1V03.ToDocument() method. The returned DTCCCACNSD1V03Document value will serialize correctly according to ISO 20022 standards.
