Fund profile
As filed in the prospectus · 2026 Q1
Current income consistent with the preservation of capital.
The fund employs multiple sub-advisers with differing investment philosophies to manage a portfolio of fixed income securities spanning investment-grade corporates and government bonds, mortgage-backed securities, bank loans, and non-investment-grade debt, with each sub-adviser making independent security selections based on yield, credit ratings and other factors under the general supervision of SEI Investments Management Corporation. The fund may also use derivatives including futures, swaps, and credit default swaps to adjust interest rate and credit exposure, take long and short currency positions, and manage overall portfolio risk. Because each sub-adviser independently selects securities of different types and maturities, the fund's actual composition and performance may diverge from the broad U.S. fixed income market, though the fund targets a dollar-weighted average duration consistent with the Bloomberg U.S. Aggregate Bond Index.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Bonds | 90.84% |
| Securitized | 12.71% |
| Derivatives | 11.06% |
| Cash & short-term | 3.69% |
| 2 smaller | 0.45% |
| Other | -0.38% |
These positions come to 118.38% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.
The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.
Derivatives are shown at market value, not notional exposure.
Sector allocation
The same holdings as Allocation above, grouped by market sector instead of asset type · as of 2026 Q2
| Government | 59.0% |
| Other | 15.8% |
| Securitized | 10.4% |
| Financials | 3.6% |
| 12 smaller | 11.2% |
Government, Securitized and Cash are non-corporate buckets; International is foreign holdings we don’t sector-classify, and Other is the residual (held funds, unresolved names).

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 |
|---|---|---|---|---|---|
| +2.31% | +10.18% | -2.78% | 3.37% | -4.38% | |
| +2.54% | +10.92% | -1.75% | 3.40% | -4.32% | |
| +2.79% | +11.74% | -0.53% | 3.37% | -4.21% |
These classes hold the same portfolio, so the 2.25pp spread over 5 years is the cost difference between them — roughly 0.45pp 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 | 90.1% |
| Floating rate | 9.3% |
| Zero-coupon or unclassified | 0.5% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.1% |
| 1-3y | 14.5% |
| 3-5y | 13.2% |
| 5-10y | 15.9% |
| 10y+ | 55.4% |
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 | 61% |
| Credit spreads | 39% |
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 | +3.31 yr |
| High yield | +0.54 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 | 0.01 yr | 0% |
| 1 yr | 0.63 yr | 10% |
| 5 yr | 1.75 yr | 29% |
| 10 yr | 2.39 yr | 40% |
| 30 yr | 1.24 yr | 21% |
| 3 mo | 0.02 yr | 1% |
| 1 yr | 0.40 yr | 10% |
| 5 yr | 1.21 yr | 31% |
| 10 yr | 1.68 yr | 44% |
| 30 yr | 0.55 yr | 14% |
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 6.02 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.
