Swing Pricing

Protecting holders from fund dilution


Preamble: Fundamental principles adopted by Ostrum Asset Management

In its wish to safeguard the interests of its long-term holders, Ostrum Asset Management has decided to introduce the swing pricing mechanism based on the methodology recommended by the French Asset Management Association's (AFG) charter.

The introduction of swing pricing solely concerns funds that would benefit from this mechanism.

A shareholder who purchases or redeems an amount below the threshold is not guaranteed to be executed on an unswung NAV. Indeed, the swing pricing trigger is appreciated globally, taking into account all inflows/outflows, ie the net balance of subscriptions / redemptions of all shareholders.

Moreover, Ostrum Asset Management has the right to change at any time the swing pricing parameters, especially during a crisis situation.

A FAQ is available on NAM’s website. The purpose of these FAQs is to respond to the various questions of holders regarding the working of the mechanism and its impacts. It applies to professional and non-professional clients within the meaning of the Markets in Financial Instruments Directive.
