Colonial First State Global Asset Management (CFSGAM) has been appointed to manage a $1.3-billion domestic fixed interest portfolio for UniSuper.
The mandate of government and semi-government bonds was won after a competitive tender.
CFSGAM already manages UniSuper's cash, mortgage-backed securities and unlisted infrastructure assets.
"This appointment recognises our existing track record managing assets for UniSuper and underscores our strong capability in delivering tailored investment management solutions to our clients," CFSGAM co-head of global fixed interest and credit Warren Bird said.
"More than ever, institutional investors are seeking solutions which balance outcomes with appropriate research, risk and portfolio management processes to deliver a full suite of investment services."
CFSGAM also acted as the transition manager for UniSuper's portfolio.
"Rather than using an external transition manager, we undertook the process internally," a CFSGAM spokesperson said.
