Fund profile
As filed in the prospectus · 2025 Q3
The Fund seeks total return, primarily through current income.
The fund invests at least 80% of its assets in investment-grade bonds and fixed-income securities across all types—government, corporate, mortgage-backed, asset-backed, and senior loans—while retaining discretion to hold up to 20% in non-investment-grade high-yield bonds. The adviser performs its own credit analysis rather than relying on ratings alone and may overweight or underweight individual securities and sectors relative to the Bloomberg U.S. Aggregate Bond Index to seek outperformance. Because the fund's allocations can diverge from its benchmark index, performance may differ materially from index returns.

| TIDPX | 0.45% | 0.45% |
| TIBHX | 0.43% | 0.43% |

Net is what a holder pays after the adviser's contractual waiver; gross is before it. A waiver can expire.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
| Share class | 1-year | 3-year | 5-year | Vol | Worst fall |
|---|---|---|---|---|---|
| +4.72% | +13.05% | +2.92% | 3.42% | -5.72% | |
| +4.35% | +12.22% | +1.63% | 3.40% | -5.81% | |
| +4.27% | +12.01% | +1.36% | 3.41% | -5.84% | |
| +4.45% | +12.53% | +2.05% | 3.36% | -5.79% | |
| +4.57% | +12.69% | +2.22% | 3.35% | -5.67% | |
| +5.01% | +14.01% | +4.39% | 3.42% | -5.58% |
These classes hold the same portfolio, so the 3.03pp spread over 5 years is the cost difference between them — roughly 0.61pp a year — not a difference in what they own.
May 2026 and Jun 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.
Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-06-30
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 86.8% |
| Floating rate | 13.2% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 2.0% |
| 1-3y | 7.8% |
| 3-5y | 11.1% |
| 5-10y | 19.3% |
| 10y+ | 57.1% |
| Unknown | 2.6% |
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 nearly 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 | 50% |
| Credit spreads | 50% |
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 | +5.25 yr |
| High yield | +0.36 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 3 mo | 0.15 yr | 3% |
| 1 yr | 0.20 yr | 4% |
| 5 yr | 0.88 yr | 16% |
| 10 yr | 1.74 yr | 31% |
| 30 yr | 2.67 yr | 47% |
| 3 mo | 0.03 yr | 0% |
| 1 yr | 0.23 yr | 4% |
| 5 yr | 0.93 yr | 17% |
| 10 yr | 1.81 yr | 32% |
| 30 yr | 2.61 yr | 47% |
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.
