Fund profile
As filed in the prospectus · 2026 Q1
The investment objective of iShares U.S. Long Credit Bond Index Fund (the Fund), a series of BlackRock Funds SM (the Trust), is to seek to provide investment results that correspond to the total return performance of fixed-income securities, in aggregate, as represented by the Bloomberg U.S. Long Credit Index (or the Underlying Index).
The fund tracks the Bloomberg U.S. Long Credit Index, a capitalization-weighted index of investment-grade corporate and government bonds with maturities of ten years or longer, using sampling techniques to approximate the index's total return rather than holding all constituents. Because the fund samples the index rather than replicating it completely, its returns may diverge from the index due to differences in portfolio composition. The fund may use derivatives and securities lending to manage liquidity.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Bonds | 98.78% |
| Cash & short-term | 10.31% |
These positions come to 109.09% 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%.
Sector allocation
The same holdings as Allocation above, grouped by market sector instead of asset type · as of 2026 Q2
| Other | 12.5% |
| Utilities | 11.7% |
| Health Care | 9.8% |
| Cash | 9.5% |
| 11 smaller | 56.5% |
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).

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.
| Fixed rate | 99.9% |
| Floating rate | 0.1% |
Share of the fund's debt value in each maturity band, shortest first.
| 10y+ | 100.0% |
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 | 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 | +12.51 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 | 0.15 yr | 1% |
| 5 yr | 1.32 yr | 11% |
| 10 yr | 4.47 yr | 37% |
| 30 yr | 6.27 yr | 51% |
| 3 mo | 0.00 yr | 0% |
| 1 yr | 0.00 yr | 0% |
| 5 yr | 0.01 yr | 0% |
| 10 yr | 2.84 yr | 23% |
| 30 yr | 9.66 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.
