Perennial's general manager of investment services has departed after 11 years following his role being made redundant.
Brian Thomas joined Perennial in 2006 and was responsible for business strategy, global economic updates and retail product development.
Before Perennial, he was head of channel management and direct sales at Credit Suisse Asset Management, a financial products manager at NRMA Financial Services and director of the strategy and research team at Macquarie.
He has also held roles at National Benefits Consulting Group, AM Corporation and Capita Financial Group.
Perennial managing director John Murray commented: "I wish to thank Brian for the considerable effort that he has made over his 11-year period with the company and wish him well in future endeavours."
Perennial made several key appointments late last year, including Cesar Farfan as head of retail in October. Farfan joined Perennial's investment team in 2015, prior to which he served as a business development manager for IOOF's trustee business. He has also previously held roles with NAB, Macquarie and Westpac.
In November, Perennial appointed Grant Oshry as head of mid-caps and Andrew Smith as head of smaller companies and micro-caps. Oshry previously headed up Perennial's small-cap business since 2007, and Smith worked as Perennial's co-small cap portfolio manager over the past nine years.
Murray said at the time that "Grant will now expand his portfolio management and analytical responsibilities in the mid cap segment where he already has an extensive knowledge of listed companies, given many have been promoted from the smaller companies' universe over the years."
Smith's appointment, meanwhile, was described as "a natural step and provides him with the opportunity to take on greater responsibility and capitalise on his extensive investment experience for the benefit of investors."
