Morningstar Australasia chief executive Andrew Bird will step down from the top job and take an advisory role with the company.
Bird was Aspect Huntley chief executive and joined Morningstar in 2006, when the firm bought Aspect Huntley. He became Morningstar Australasia chief executive in 2007.
He founded Aspect Financial in 1997, which merged with Huntley's Investment Information to form Aspect Huntley in 2008.
"Andrew has done a terrific job and led the integration of Aspect Huntley into Morningstar. We wish him the best in his new endeavours and we are delighted that he'll stay on with us in an advisory capacity," Morningstar international president Bevin Desmond said.
Bird said he will be focusing on his investments in two early-stage software companies.
"I've thoroughly enjoyed leading Morningstar's Australian operations for the past several years. Now that the merger between Aspect Huntley and Morningstar has been finalised, it is the right time to move on and focus on my other interests," he said.
"We have a good management team in place and I am looking forward to remaining with the company in an advisory capacity."
Bird will officially step down at the end of March and will act in an advisory role after that time.
Morningstar Australasia is currently searching for a new chief executive.
