Asset Servicing Working Group


The Asset Servicing Working Group has identified the following four key topics as key to the securities services industry:

  • Data Sourcing: The WG will work with The Value Exchange on a data sourcing survey for Corporate Action events. The results will enable the WG to provide guidance on the use of a golden copy for key events
  • Withholding Tax: One area of concern highlighted as a result of the pandemic is the area of withholding tax processing. The WG will review the current issues and look at how these could potentially be addressed for both tax reclaims and relief at source
  • Proxy Voting: The WG plans to analyze and document Proxy Voting market practises
  • Complex Corporate Action Events: The WG will identify issues around processing complex corporate action events and aim to provide best practise guidance

During 2021, the Working Group will focus on the initial two topics.
