The iShares 10+ 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 greater than ten years.
The fund tracks the ICE BofA 10+ Year US Corporate Index using representative sampling, holding a portfolio of investment-grade corporate bonds with remaining maturities of ten years or more that collectively mirrors the index's characteristics. Because the fund may not hold all index components, its returns may diverge from the index. A significant portion of the index is concentrated in the financials sector.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Bonds | 98.09% |
| Cash & short-term | 11.57% |
These positions come to 109.66% 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%.

How it has done
IGLB share class · total returns with dividends reinvested
Volatility over the last 12 months: 6.09%. Past returns are a record, not a forecast.
Jun 2026 and Jul 2026 and Aug 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 2026-05-31
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 | 0.0% |
| 5-10y | 0.1% |
| 10y+ | 99.8% |
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 | +12.25 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 | 0.14 yr | 1% |
| 5 yr | 1.29 yr | 11% |
| 10 yr | 4.44 yr | 37% |
| 30 yr | 6.09 yr | 51% |
| 3 mo | 0.00 yr | 0% |
| 5 yr | 0.01 yr | 0% |
| 10 yr | 2.85 yr | 23% |
| 30 yr | 9.40 yr | 77% |
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.
