iShares Russell 2000 Index Fund (the Fund) seeks investment results that correspond generally to the price and yield performance of the Russell 2000 Index (the Index).

The Index is a subset of the Russell 3000 Index, and serves as the underlying index for the Russell 2000 Growth and Value Index series. Component companies are adjusted for available float and must meet objective criteria for inclusion to the Index. BlackRock Fund Advisors (BFA) serves as the investment adviser to the Fund.
