The Fund aims to achieve a total return on your investment, through a combination of capital growth and income on the Funds assets, which reflects the return of the ICE US Treasury 10-20 Year Bond Index, this Funds Benchmark Index. The Index offers exposure to US government bonds with a remaining maturity (i.e. the time from issue until they become due for repayment) from 10 to 20 years and a minimum amount outstanding of $300 million at the time of inclusion in the Index.
