Claims policy for refund of foreign withholding tax for mutual funds managed by Ostrum Asset Management/Natixis Investment Managers International

French and Luxembourg mutual funds may receive dividends net of withholding tax on foreign securities held. The withholding tax rate applied to dividends for French and Luxembourg mutual funds may in certain cases be different from the rate applicable to dividends paid to mutual funds in the security issuer’s state.

Following the ruling from the European Court of Justice of May 10, 2012, this means that claims can be filed with the relevant authorities in certain European Union countries for a refund of the difference in rate.

The asset manager’s policy is to file these claims for the mutual funds it manages, when there is a reasonable likelihood of obtaining a refund at a reasonable cost and in a reasonable timeframe in the interests of and on behalf of investors, and materiality thresholds may be assessed with this in mind.

However, the effective and definitive amounts of refund and the timeframe can vary, so the mutual funds may incur external costs without benefiting from the refunds expected. The fees spent and refunds obtained as part of this policy will be outlined in the mutual funds’ annual reports.

On 3 April 2018, Natixis Asset Management became Ostrum Asset Management.
