iShares US Mortgage Backed Securities UCITS Acc is a bonds ETF from iShares tracking the US Mortgage Backed Securities index through physical replication. Domiciled in Ireland and launched in 2017, the fund manages about 2.4 bn € and charges a TER of 0.28% — 28 € per year on a €10,000 investment. Income is automatically reinvested in the fund (accumulating).
iShares US Mortgage Backed Securities UCITS Acc competes with 2 other products on the same index (US Mortgage Backed Securities): it ranks 1st by fund size and 1st by ongoing cost, with a TER of 0.28% against a group median of 0.28%. It has been listed since 2017, 9 years of track record.
On a €10,000 investment the TER costs 28 € a year, and no product in the group costs less.
Replication is physical: the fund holds the underlying securities directly. The ten largest positions account for 25.5% of the portfolio.
Income is accumulated: no distribution is paid out, the share price absorbs it. In a savings plan this removes the need to reinvest dividends by hand. The fund is denominated in USD. That is not the same as currency risk: the exposure comes from the currencies of the underlying holdings, not from the denomination or the trading currency of a given listing.
The fund is domiciled in Ireland, which determines the tax treatment of income received by the fund and the supervisory authority.
