The sub-fund aims to track, before expenses, the price and income performance of the Bloomberg MSCI US Liquid Corporates 1-5 Year Sustainable Index (Total Return) (this sub-fund's "Index"). Additionally currency hedged share classes aim to reduce the impact of currency fluctuations between their reference currency and the index currency by selling currency forwards at the one-month forward rate in accordance with the hedging methodology of the Index's currency-hedged index variant.
