Pension funds hold controlling stakes in various companies (private and public) globally. It’s not uncommon for a US or Canadian pension fund to hold a controlling stake in a private European business. Meaning they often have indirect influence over the actions of corporations. The same applies to hedge funds or investment vehicles controlled by activist investors. Why would a US pension fund care about paying tax in France? I could understand why it matters if they paid tax in the US (even though a CA based fund probably wouldn’t care about contributing in NY), but what do they have to gain by overpaying tax in France?
