Fund profile
As filed in the prospectus · 2026 Q1
Vanguard Institutional Intermediate-Term Bond Fund (the Fund) seeks to provide a high level of current income consistent with the maintenance of principal and liquidity.
The fund is actively managed and invests primarily in a diversified portfolio of short- and intermediate-term bonds rated A3 or better, maintaining a dollar-weighted average maturity of 3 to 10 years. It may use derivatives including interest rate swaps, credit default swaps, and fixed income futures, as well as take short positions in mortgage-backed securities. Because the fund's returns depend on the manager's security selection and use of derivatives, performance will diverge from any benchmark.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q1

| Cash & short-term | 0.15% |
| Derivatives | -0.07% |
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.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Feb 2026
Mar 2026 has been filed since the trailing figures were struck, so it is 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 2026-03-31
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 | 79.9% |
| Floating rate | 20.1% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 2.3% |
| 1-3y | 16.3% |
| 3-5y | 23.0% |
| 5-10y | 19.3% |
| 10y+ | 39.1% |
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 2026Q1
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 | 56% |
| Credit spreads | 44% |
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 | +3.01 yr |
| High yield | +0.00 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 | 0.86 yr | 22% |
| 5 yr | 1.64 yr | 42% |
| 10 yr | 1.16 yr | 30% |
| 30 yr | 0.25 yr | 6% |
3 mo is NEGATIVE (-0.03 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.02 yr | 1% |
| 1 yr | 0.55 yr | 18% |
| 5 yr | 1.31 yr | 44% |
| 10 yr | 0.98 yr | 33% |
| 30 yr | 0.15 yr | 5% |
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 3.87 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.
