French to English Bus/Financial Investment / Securities Equity report

I'm translating an equity report for an asset-management company from French (France) to English (United Kingdom) and am having trouble with a phrase. Please find it below in a full sentence to give you full context:

'Le profil de risque de l'OPCVM Nourricier [x] est similaire à celui de l'OPCVM Maître [y] défini ci-dessous, exception faîte que le Fonds Nourricier pourra prendre des positions, dans la limite de 15% de son Actif Net, en vue de couvrir son portefeuille à l'exposition de son FCP Maître aux risques actions.'

I'm thinking along the lines of 'hedging its portfolio... of its Master Fund', but I'm not sure how to fit the 'à l'exposition de' into the English. Could someone help please?

Many thanks!
