Proxy advisory firm Institutional Shareholder Service (ISS) recommended shareholders support Royal Dutch Shell’s (RDSa.L) plan to move its head office from the Netherlands to Britain, according to a document seen by Reuters. Shell said this month it would scrap its dual Anglo-Dutch share structure and move its head office to London from The Hague due to the Dutch tax system and after a court ruling over its strategy to reduce greenhouse gas emissions. “The Company has provided compelling rationale which explains the benefits of the simplification of its share structure,” ISS said in a note. The move will be brought to vote at a special general meeting on Dec. 10.
