Natixis Asset Management has confirmed the resignation of its director general Pascal Voisin following reports breaking last week in French publication L’Agefi, according to Reuters.
Voisin is understood to have emailed his staff on Thursday evening (10 March) informing them of his decision.
Reuters says a board meeting would take place this week and an announcement on the successor to Voisin would follow.
Voisin had been chief executive of Natixis AM, an affiliate of Natixis Global Asset Management, since 2007.
His earlier positions have included deputy chief executive and chief investment officer at Crédit Agricole AM.
Natixis AM is part of French banking group BPCE.
At 31 December 2015 the multi-affiliate group ran $870.3bn ( £606.2bn) in assets under management.
