Thomas Wells, who was previously an assistant fund manager, has been promoted to fund manager on the range and Paul Parascandalo, lead manager of the Aviva with profits fund, is now a fund manager on the MAF team.
They both join Peter Fitzgerald (pictured) and Nick Samouilhan as fund managers on the range, according to Aviva Investors.
Three of the funds in the multi-asset range were launched in November 2010, followed by another two in February 2012.
The funds are designed to provide capital growth by investing across global asset classes, with each fund suited to a different risk appetite.
Mr Fitzgerald said: “The joint UK and Irish Multi-Asset fund range is now close to £2bn and is seeing substantial growth. The addition of Thomas and Paul as fund managers reaffirms our commitment to these funds and will help to ensure continued success.”
