Two investment trust managers at Janus Henderson are to retire from the business.
Ian Barrass, who jointly ran the £108m Henderson Alternative Strategies investment trust, is to leave the business due to an ongoing health issue.
His co-manager on the trust, James De Bunsen, will remain at the helm of the trust, and be joined by Peter Webster, a Janus Henderson employee who will become co-manager.
Mr Barrass had jointly managed the trust since 2013 and had been an employee since 2005.
He initially joined as a partner in Henderson's private equity business.
Henderson Alternatives Trust invests in a variety of alternative assets, including specialist property, and hedge funds.
The company has also announced that Colin Hughes is to step down as co-manager on the £99m Henderson Opportunities trust.
This fund is also managed by James Henderson.
Laura Foll, who is presently joint manager with Mr Henderson on the Henderson UK Income fund, will become co-manager of the Henderson Opportunities trust.
This is a UK equity mandate that invests in companies across the multi-cap spectrum, using the value style of investing.
Mr Henderson is a fund manager whose preference at present is for companies in the industrial sector of the market.
Mr Hughes is retiring after 20 years with the firm.
