trustees must invest with the care which an ordinary prudent person would take in investing for the benefit of other people for whom they felt morally bound to provide. As the purpose of the scheme is the provision of benefits for members and other beneficiaries, trustees must invest solely in their best interests. In this context “best interests” should be taken to mean best financial interests. Trustees must also invest the assets of the scheme in a manner appropriate to the circumstances of the scheme, i.e. they must review the general circumstances, such as the age profile, of the members of the scheme and invest the assets appropriately (par. 3.7)
