iShares Russell Small/Mid-Cap Index Fund Investor A Shares 

The fund's primary objective is to mirror the investment returns of the Russell 2500™ Index. This index specifically tracks the performance of U.S. companies with small to medium market capitalizations, a category frequently referred to as "smid-cap" within the American equity landscape. Notably, the Russell 2500™ Index is derived from the larger Russell 3000® Index. To achieve its goal, the fund typically allocates at least 90% of its total assets—including any funds obtained through borrowing for investment purposes—to securities that comprise its benchmark index.
