Fund profile

As filed in the prospectus · 2026 Q2

The investment objective of iShares Russell 2000 Small-Cap Index Fund (Russell 2000 Small-Cap Index Fundor the Fund), a series of BlackRock Index Funds, Inc. (the Corporation), is to match the performance of the Russell 2000 Index (the Russell 2000 or the Underlying Index ) as closely as possible before the deduction of Fund expenses.

Strategy · summarised

The fund employs a passive strategy to track the Russell 2000 Index, holding a statistically selected sample of the index's small-cap stocks chosen to match the index's market capitalizations, industry weightings, and fundamental characteristics. Because the fund may not hold all index constituents or use identical weightings, its performance may diverge from the Russell 2000. The fund invests through a master/feeder structure, with all assets held in a master fund that mirrors the fund's strategy and objectives.

May 2026 and Jun 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.

This fund changed legal form during the period shown. The history above is continuous — it spans both eras, and the change is not a gap in reporting.
