About this fund
What you own
The ICE BofA US Treasury Bill Index index is the benchmark this fund aims to copy. By holding it, this fund gives you a stake in around 42 companies across United States in a single purchase.
How it works
The fund actually buys every share in the index it tracks (full replication).

Owning every holding keeps things transparent — what is in the index is what the fund actually owns. It can be a touch costlier to run for indexes with thousands of tiny positions, since the fund has to buy and maintain them all. There is no swap bank involved, so there is no extra “what if the partner fails” question to weigh.
Cost
The yearly running cost of the fund, shown as a % of your money. Lower is cheaper.

For example, a 0.20% fee works out at €0.20 a year for every €100 invested — that’s a generic illustration of the mechanic, not this fund’s own fee. It is skimmed quietly from inside the fund a little each day, so you never get a bill — but it drags on your return every year you hold. On a broad index ETF it is usually a small fraction of a percent; the gap between a cheap and a pricey fund looks tiny on day one but compounds over decades, which is why it is worth a glance.
