The iShares 1-5 Year Investment Grade Corporate Bond ETF (the Fund ) seeks to track the investment results of an index composed of U.S. dollar-denominated, investment-grade corporate bonds with remaining maturities between one and five years.
The fund tracks the ICE BofA 1-5 Year US Corporate Index using representative sampling, holding a portfolio of investment-grade corporate bonds with one to five years to maturity that collectively mirrors the index's characteristics rather than holding all constituents. Because the fund may not hold all index components, its returns may diverge from the index. The fund concentrates its holdings in industries to the same extent as the underlying index, which as of February 2026 held a significant portion in financials.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Bonds | 99.18% |
| Cash & short-term | 6.32% |
These positions come to 105.50% 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%.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-05-31
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 | 99.9% |
| Floating rate | 0.1% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.6% |
| 1-3y | 44.9% |
| 3-5y | 48.0% |
| 5-10y | 5.3% |
| 10y+ | 1.3% |
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 | 51% |
| Interest rates | 49% |
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 | +2.82 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.
| 3 mo | 0.01 yr | 0% |
| 1 yr | 0.71 yr | 26% |
| 5 yr | 2.00 yr | 74% |
10 yr and 30 yr are NEGATIVE (-0.00 yr, -0.00 yr) — a deliberate hedge at that point on the curve, so they are not part of the band above.
| 3 mo | 0.00 yr | 0% |
| 1 yr | 0.62 yr | 22% |
| 5 yr | 2.20 yr | 78% |
| 10 yr | 0.00 yr | 0% |
| 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.
