Corporate Action Notices
If a structured product references an underlying asset that becomes subject to a corporate action, the action will usually require an adjustment to be made to the strike price of that asset. Some examples of corporate actions where this might be necessary include rights issues, mergers, de-mergers, takeovers, share splits and share consolidations.
When such an event occurs, NYSE Liffe will issue a Corporate Action Notice based on its Corporate Actions Policy to determine the ratio that ought to be applied to strike prices for contracts that reference that particular share.
