170As regards the first point, the mere fact that a public undertaking has already made capital injections into a subsidiary which are classed as ‘aid’ does not automatically mean that a further capital injection cannot be classed as an investment which satisfies the private market economy investor test. Nevertheless, it is the Court's view that in a case such as this, which concerns three capital injections made by the same investor over a period of two years, the first two of which brought no return, the Commission must determine whether the third injection could reasonably be severed from the first two and classed, for the purposes of the private investor test, as an independent investment.
