Volatility over the last 12 months: 3.34%. Past returns are a record, not a forecast.

Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.

Features
Master-feeder

This fund files no prospectus profile. Unit investment trusts and closed-end funds register on forms that carry no objective or fee tagging, and some fund families file without it — a gap in what was filed, not a fund without an objective or without fees.

Classified from what the fund holds, not from its name · 2026 Q2. The summary is a paraphrase of the prospectus; the objective is verbatim.

Risk profile

Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2

Most of this fund’s sensitivity is to interest rates, with credit spreads carrying about half as much.

6.01 yr
approx. move per 100bp
2.17 yr
approx. move per 100bp
If rates and spreads both rise 100bp

Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.

of value
Interest rates74%
Credit spreads26%

Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.

Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.

The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
