Fund performances for periods greater than 12 months are annualised.These change over time percentages only consider the price movements of the fund and do not take dividends or distrubutions into account. This reflects the NAV performance of the fund and is useful for investors who do not want to reinvest their income back into the fund but still want to track their investments over time. This is not the Total Return Index (TRI) performance, which is calculated using the distributions of the fund to buy more units.
