12. Additional informationxvi:

In reference to Section 10, the shares detailed are managed by the named discretionary investment management entity within multiple portfolios on behalf of underlying clients, based on investment management agreements whereby the client has delegated the exercise of the voting power to the referenced investment manager.

This is a retrospective disclosure to reflect confirmation received from the Issuer that its Home Member State for the purposes of the Irish Transparency Rules is Ireland. Prior to this confirmation, the aggregate of Standard Life Aberdeen plc affiliated investment management entities with delegated voting rights on behalf of multiple managed portfolios had treated the Home Member State of Grafton Group plc as the United Kingdom and, as such, monitored the percentage of total voting rights held in accordance with the UK Financial Conduct Authority's Disclosure and Transparency Rules sourcebook.

The disclosure was due to the Completion of the court-sanctioned scheme of arrangement and all-share merger under Part 26 of the Companies Act 2006 of Aberdeen Asset Management PLC and Standard Life plc which became effective on 14 August 2017. As a consequence various investment management companies having delegated voting rights across a number of client portfolios became affiliated entities (per FCA Glossary definition) and threshold limits were triggered.
