T. Rowe Price Small-Cap Index I (null) Fonds

Under normal conditions, the fund invests at least 80% of its net assets (including any borrowings for investment purposes) in small-cap stocks and in stocks that are included in its benchmark index. The index, which is constructed by the Russell Investment Group, is designed to measure the performance of the small-cap segment of the U.S. equity universe. It includes approximately 2,000 small-cap U.S. securities based on a combination of their market capitalization and index membership, without consideration of a growth or value style.
