About this fund
Fund objectives
- The Fund employs a passive management – or indexing – investment approach and seeks to track the performance of the Bloomberg U.S. Government Float Adjusted Bond Index (the “Index”).
- The Index includes US dollar-denominated US government and government related bonds with maturities greater than one year.
- The Fund attempts to: 1. Track the performance of the Index by investing in a portfolio of securities that, insofar as possible and practicable, consists of a representative sample of the component securities of the Index. 2. Remain fully invested except in extraordinary market, political or similar conditions.
