(21)To maintain the necessary flexibility in its investment portfolio, qualifying social entrepreneurship funds should be able to invest in assets other than qualifying investments to the extent that those other investments do not exceed the 30 % threshold for non-qualifying investments. Holdings of cash and cash equivalents should not be taken into account for the calculation of that threshold because such holdings are not to be considered as investments. Qualifying social entrepreneurship funds should invest in a manner consistent with their ethical investment strategy, for instance they should not undertake investments that finance the weapons industry, that risk breaches of human rights or that entail electronic waste-dumping.
