CorporateActionInstructionV04

seev.033.001.04

Scope An account owner sends the CorporateActionInstruction message to an account servicer to instruct election on a corporate action event. This message is used to provide the custodian with instructions on how the account owner wishes to proceed with a corporate action event. Instructions include investment decisions regarding the exercise of rights issues, the election of stock or cash when the option is available, and decisions on the conversion or tendering of securities. Usage The message may also be used to:

re-send a message previously sent (the sub-function of the message is Duplicate),
provide a third party with a copy of a message for information (the sub-function of the message is Copy),
re-send to a third party a copy of a message for information (the sub-function of the message is Copy Duplicate), using the relevant elements in the business application header (BAH). ISO 15022 - 20022 COEXISTENCE This ISO 20022 message is reversed engineered from ISO 15022. Both standards will coexist for a certain number of years. Until this coexistence period ends, the usage of certain data types is restricted to ensure interoperability between ISO 15022 and 20022 users. Compliance to these rules is mandatory in a coexistence environment. The coexistence restrictions are described in a Textual Rule linked to the Message Items they concern. These coexistence textual rules are clearly identified as follows: “CoexistenceXxxxRule”.

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.

ChangeInstructionIndicator building block

When used in a corporate action instruction, indicates that the current instruction is replacing a previous one that was cancelled earlier. When used in a corporate action instruction cancellation request, indicates that cancelled instruction will be replaced by a new corporate action instruction to be sent later. Indicates a “Yes” or “No” type of answer for an element. For comparison, see the ISO20022 official specification This message is declared as YesNoIndicator in the ISO specification. In our implementation, it is represented in source code as IsoYesNoIndicator. Due to global using directives, it is treated as a System.String by the compiler and runtime.

CancelledInstructionIdentification building block

Identification of a previously sent cancelled instruction document. Identification of a document and type of link. For comparison, see the ISO20022 official specification

Extensibility and generalization considerations

To facilitate generalized design patterns in the system, the CorporateActionInstructionV04 implementation follows a specific implementaiton pattern. First of all, CorporateActionInstructionV04 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, CorporateActionInstructionV04Document implements IOuterDocument. Because CorporateActionInstructionV04 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type CorporateActionInstructionV04.

classDiagram
    class IOuterRecord
    CorporateActionInstructionV04 --|> IOuterRecord : Implements
    CorporateActionInstructionV04Document --|> IOuterDocument~CorporateActionInstructionV04~ : Implements
    class IOuterDocument~CorporateActionInstructionV04~ {
        CorporateActionInstructionV04 Message
     }

Document wrapper for serialization

The only real purpose CorporateActionInstructionV04Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:seev.033.001.04’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using CorporateActionInstructionV04.ToDocument() method. The returned CorporateActionInstructionV04Document value will serialize correctly according to ISO 20022 standards.
