Fund profile
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.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-04-30
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Floating rate | 90.1% |
| Fixed rate | 5.5% |
| Zero-coupon or unclassified | 4.4% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.1% |
| 1-3y | 16.6% |
| 3-5y | 30.6% |
| 5-10y | 51.2% |
| 10y+ | 1.5% |
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
Interest-rate moves barely touch this fund — but its credit exposure is real: a 100bp widening in credit spreads costs roughly 5.0%. Duration alone would have told you none of that.
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.
| Credit spreads | 96% |
| Interest rates | 4% |
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.
| High yield | +4.92 yr |
| Investment grade | +0.17 yr |
Share of duration at each point, shortest first. This filer signs its rate and credit disclosures differently; the direction shown follows its interest-rate filing, and a negative reading is the least-supported figure here.
| 3 mo | 0.08 yr | 35% |
| 1 yr | 0.04 yr | 18% |
| 5 yr | 0.09 yr | 40% |
| 10 yr | 0.02 yr | 7% |
| 30 yr | 0.00 yr | 1% |
| 3 mo | 0.02 yr | 0% |
| 1 yr | 0.79 yr | 16% |
| 5 yr | 3.76 yr | 74% |
| 10 yr | 0.51 yr | 10% |
| 30 yr | 0.00 yr | 0% |
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.

Dollar change per 1bp of spread movement, as filed and sign-anchored. A blank cell was not filed; a zero was.
Duration contribution in years, summing to the fund's 0.24 yr.
This is where the fund's rate exposure sits, not its currency risk — most international bond funds hedge the currency back to dollars, and the size of those hedges is not in the filing. Tenors are also summed across curves, so a 5-year JPY point and a 5-year USD point are added together.
