Scope The CorporateActionInstruction message is sent by an account owner 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).
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
Indicates that the current instruction is replacing a previous one that was cancelled earlier. 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

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the CorporateActionInstructionV12 implementation follows a specific implementaiton pattern. First of all, CorporateActionInstructionV12 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, CorporateActionInstructionV12Document implements IOuterDocument. Because CorporateActionInstructionV12 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type CorporateActionInstructionV12.
classDiagram class IOuterRecord CorporateActionInstructionV12 --|> IOuterRecord : Implements CorporateActionInstructionV12Document --|> IOuterDocument~CorporateActionInstructionV12~ : Implements class IOuterDocument~CorporateActionInstructionV12~ { CorporateActionInstructionV12 Message }
Document wrapper for serialization
The only real purpose CorporateActionInstructionV12Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:seev.033.001.12’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using CorporateActionInstructionV12.ToDocument() method. The returned CorporateActionInstructionV12Document value will serialize correctly according to ISO 20022 standards.
