Fund profile
As filed in the prospectus · 2026 Q1
The investment objective of the DFA One-Year Fixed Income Portfolio (the One-Year Portfolio or the Portfolio) is to achieve a stable real return in excess of the rate of inflation with a minimum of risk.
The fund invests in investment-grade fixed income securities maturing within one year, focusing on certificates of deposit, commercial paper, bankers acceptances, and short-term notes and bonds issued by U.S. and foreign governments, agencies, banks, and corporations. The manager tilts toward longer-maturity securities within the eligible range when the expected term premium justifies it, otherwise favoring shorter maturities. The fund maintains a weighted average effective maturity not exceeding one year and may use futures and options to adjust interest rate exposure or manage cash flows.

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 | 65.2% |
| Fixed rate | 34.8% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 32.0% |
| 1-3y | 68.0% |
Based on what filers reported; a filer that never reported a flag also reads as none.
Risk profile
Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2
More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.
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 | 53% |
| Interest rates | 47% |
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 | +0.31 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 | 0.11 yr | 40% |
| 1 yr | 0.16 yr | 57% |
| 5 yr | 0.01 yr | 4% |
| 30 yr | 0.00 yr | 0% |
10 yr is NEGATIVE (-0.00 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.02 yr | 8% |
| 1 yr | 0.25 yr | 81% |
| 5 yr | 0.03 yr | 11% |
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.
