Which risk response is applied on a pain/gain basis?

The risk response type that is applied on a pain/gain basis is 'Share'. Sharing involves partnering with others to share the impact of the risk. This is often used for both threats and opportunities where sharing the risk can enhance the capability to capitalize on the opportunity or mitigate the threat, with potential gains or savings being distributed according to an agreed formula.References: PRINCE2® 7 Foundation handbook and documents.
