Declared duration, reading by reading

The issuer’s readings archived by Rebalix at each re-reading (on the 2nd and 17th of the month, since 7 October 2026) and, for earlier months, in the monthly registry snapshots since September 2026. “As of” is the date of the figure at the issuer; “Read on” is the day Rebalix archived it. The kind is the one the issuer publishes (modified, effective or average); nothing is estimated or converted. A jump above 1.5 years and above 30% also appears as an event below.

The Holdings column counts the snapshot’s positions as declared by the issuer, cash and duplicate lines included; the comparison in “What changed” excludes cash and merges lines of the same holding — the two totals may differ. The latest month’s AUM is the most recent value of the ongoing month.
Month-on-month comparisons (holdings added, removed, weight changes) start with the 2 September 2026 snapshot. The basket snapshot archive starts in August 2026.
