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.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-05-31
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 80.1% |
| Floating rate | 14.7% |
| Zero-coupon or unclassified | 5.2% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.4% |
| 1-3y | 9.5% |
| 3-5y | 14.3% |
| 5-10y | 34.5% |
| 10y+ | 40.3% |
These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.
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.
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.
| Interest rates | 66% |
| Credit spreads | 34% |
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 the fund's spread duration carried by each credit tier.
| Investment grade | +3.13 yr |
| High yield | +0.06 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 1 yr | 0.54 yr | 9% |
| 5 yr | 1.68 yr | 27% |
| 10 yr | 2.34 yr | 38% |
| 30 yr | 1.55 yr | 25% |
3 mo is NEGATIVE (-0.01 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.00 yr | 0% |
| 1 yr | 0.20 yr | 6% |
| 5 yr | 1.11 yr | 35% |
| 10 yr | 1.46 yr | 46% |
| 30 yr | 0.41 yr | 13% |
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.
