Investment Objective
The fund seeks to track the performance of a benchmark index that measures the investment return of small- and mid-capitalization U.S. stocks.
Strategy
The fund attempts to match the investment return of small- and mid-capitalization U.S. stocks by seeking to match the performance of its benchmark index, the Standard & Poor's Completion Index (S&P Index). The S&P Index consists of primarily small- and mid-capitalization stocks and generally includes those U.S. stocks that are not included in the Standard & Poor’s 500 Stock Index.

All investments are subject to market risk, including possible loss of principal. Stocks can decline for many reasons, including adverse political or economic developments here or abroad, changes in investor psychology, or heavy institutional selling. Because the fund invests primarily in securities issued by small-and mid-cap companies, it is likely to be more volatile than a fund that focuses on securities issued by larger companies. Small- and medium-sized companies often have less experienced management, narrower product lines, more limited financial resources, and less publicly available information than larger companies. In addition, smaller companies are typically more sensitive to changes in overall economic conditions and their securities may be difficult to trade. Because the fund is designed to track the S&P Completion Index, it does not have the flexibility to shift assets toward stocks or sectors that are rising or away from stocks or sectors that are declining.
**This chart displays relative risk of each U.S. mutual fund listed using standard deviation of returns. Those values are provided in the bars at the top of the chart.

Methodology: We evaluate the standard deviation and its resulting placement within a specific risk/return category on an annual basis. A fund is generally placed in a risk/return category based on the 10-year standard deviation of its performance. If a fund is less than 10 years old, the actual fund performance history is supplemented with the primary prospectus benchmark history to obtain a full 10-year history, or longest time period available up to 10 years. For an Asset Allocation fund with less than 10 years of performance history, sub-strategy returns are used. When a sub-strategy is less than 10 years old, the actual sub-strategy performance history is supplemented with benchmark history to obtain a full 10-year history, or longest time period available up to 10 years.

Risk return categories overlap; a fund with a standard deviation in the overlap between two categories, denoted by a plus (+), is placed so that its risk categorization is better aligned with anticipated return characteristics an investor may experience going forward at the discretion of T Rowe Price.

When a fund has a cash-like benchmark, denoted by a double plus (++), its standard deviation is estimated using only available fund returns. If the fund is less than 10 years old, benchmark returns are not used to obtain a full 10-year history because they would artificially suppress the volatility estimate.

All investments are subject to market risk, including the possible loss of principal. Standard deviation of returns, a measure of price volatility, is one measure of risk. Please consult the funds' prospectuses for a more complete discussion of the funds' risks.
