Under typical conditions, this fund commits at least 80% of its total investment capital (including any borrowed funds) to a portfolio predominantly made up of U.S. Treasury debt instruments. These holdings are strategically assembled to collectively achieve a mean duration of around ten years, acquired either through direct ownership or indirectly via financial contracts like derivatives. The fund's underlying index consists of particular U.S. Treasury notes and bonds that are constituents of the broader Bloomberg US Treasury Index. It operates as a non-diversified investment vehicle.
