Until the merger with Henderson Investors Watson was chief executive of AMP Asset Management, the international investment management arm of AMP, managing 30bn of AMP and third party assets. His appointment reflects Hermes decision to split the roles of chief executive and chief investment officer, both hitherto filled by Alastair Ross Goobey. Ross Goobey will now concentrate on the role of chief executive. Mark Crutchley has moved from Gartmore to Prudential Portfolio Managers, where he will become a senior member of the pension fund investment team. He will take responsibility for fund management and relationships with PPMs segregated pensions fund clients and will also be involved in the communication of UK equity strategy for pooled fund clients. Andrew Argyle has joined PPMs fixed interest team as a senior portfolio manager. He moves from Whittingdale. Martin Lennon has joined the commercial lending team as a senior lending manager and Trudie Pearce joins PPM as a credit analyst in the corporate bonds team. The board of Securities Trust of Scotland, the 450m international investment trust managed by Edinburgh-based Martin Currie, has appointed Neil Donaldson as non-executive director. Donaldson, who was formerly managing director of James Donaldson and Sons, the independent Fife-based timber merchants, is a director of several other companies, including Crieff Hydro.
