Legal & General Investment Management (LGIM) saw net inflows of £3.1 billion for the third quarter of 2013, versus an outflow of £0.2 billion a year ago.
The growth in net inflows was primarily driven by international clients division which contributed £6.9 billion. International assets now total £57 billion.
Total gross inflows between July and September were up 71% to £15.4 billion from £9 billion in the third quarter of 2012.
Net flows into institutional unit trusts were £100 million, the firm said.
L&G group chief executive Nigel Wilson said: "We are known for providing value for our 8 million customers and are working closely with government and regulators to help customers get the best possible deal.
"LGIM, whose fees average just over 0.1% and Cofunds, whose platform fees are less than 0.3%, offer outstanding value to both institutional and retail customers."
