The portfolio will be actively managed with exposure to various asset classes such as cash, bonds, equities and property, both domestically and internationally, being varied to reflect changing economic and market circumstances, in order to maximise returns for the investors. From time to time derivatives may be considered, but the manager will adhere to prevailing derivatives regulations when doing so. The portfolio shall adhere to the Multi Asset : High Equity classification requirements as set out in the Asisa Standard on Fund Classifications for South African Collective Investment Scheme Portfolios. The maximum effective equity exposure is currently limited to 75%. Investments to be included in the portfolio will, apart from assets in liquid form, consist of participatory interests in portfolios of collective investment schemes registered in the Republic of South Africa or of participatory interests in collective investment schemes or other similar schemes operated in territories with a regulatory environment which is to the satisfaction of the manager and the trustee of a sufficient standard to provide investor protection which is at least equivalent to that in South Africa. The portfolio will also be allowed to invest in listed and unlisted financial instruments (derivatives) as allowed by the Act from time to time. The Manager shall be permitted to invest on behalf of the portfolio in offshore investments as legislation permits. For the purpose of this portfolio, the Manager shall reserve the right to close the portfolio to new investors on a date determined by the Manager. This will be done in order to be able to manage the portfolio in accordance with its mandate. The Manager may, once a portfolio has been closed, open that portfolio again to new investors on a date determined by the Manager. The Trustee shall ensure that the investment policy set out in the preceding clauses are adhered to; provided that nothing contained in this clause shall preclude the Manager from varying the proportions of securities in terms of changing economic factors or market conditions or from retaining cash in the portfolio and/or placing cash on deposit.
