Understanding dedicated corporate action events

LUSID is transitioning to a system where each kind of corporate action has a dedicated event, enabling you to handle those events in a seamless and consistent manner for instruments of type Equity.

Important: Corporate action events are disabled by default. To enable them, register a recipe with every portfolio you wish events to impact. More information.

For example, LUSID emits a CashDividendEvent on the ex-date providing you have manually loaded a cash dividend corporate action in time into a source registered with the parent portfolio. In addition:

LUSID provides a CashDividendEvent default transaction template that automatically generates a transaction representing the cash dividend amount. You can override this default template if you wish, but it is not necessary.
You must implement a DividendIncome transaction type to confer a suitable economic impact on this automatically-generated transaction. We provide a recommendation, which you can either implement as-is or change if desired.

Note: Term instruments such as bonds, swaps, options and futures that mature and therefore have an intrinsic lifecycle automatically trigger LUSID to emit events. More information.

With this transaction type in place, and for each portfolio subscribed to the corporate action source and with a holding on the ex-date, LUSID automatically:

Generates an output transaction scaled to your holding in that portfolio, and enriched with extra information such as gain/loss or a tax calculation.
Implements the economic impact prescribed by the transaction type, for example adding the dividend amount to a particular cash balance.

Note you can override an event for a particular portfolio by loading an event instruction.

The following dedicated events are available or planned for instruments of type Equity and SimpleInstrument. For more information, start by calling the GetTransactionTemplateSpecification API for that event. If a particular event is not available yet, you can continue modelling any kind of corporate action as a TransitionEvent.
