A financial update Thursday said the firm recorded €42.4 billion in net inflows for the six months ended June 30, compared with €26.3 billion for the first half of 2017.
Figures for June 2017 pre-date Amundi's acquisition of Pioneer Investments, which was completed in July 2017 and added €242.9 billion in assets under management.
For the quarter, net inflows totaled €2.6 billion, compared with €39.8 billion in net inflows for the three months ended March 31, and €2.9 billion in net outflows for the quarter ended June 30, 2017.
Market effects detracted €2.1 billion from assets under management for the six months ended June 30.
Net revenue was €1.34 billion for the six months ended June 30, the same figure as for the same period in 2017. Net income was €454 million for the six-month period, up 11.8% from the same period in 2017. For the quarter, net revenues increased 2.1% to €677 million, while net income grew 5.9% to €234 million.

The update said the first-quarter net outflows related to "seasonal outflows in treasury products used by corporates," in particular to pay dividends.
