bRestated to reflect current fees.

Example This example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 year	3 years	5 years	10 years
$36	$113	$197	$443

Portfolio Turnover The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the

most recent fiscal year, the fund’s portfolio turnover rate was 5.9% of the average value of its portfolio.

Investments, Risks, and Performance

Principal Investment Strategies The fund seeks to match the performance of the entire U.S. stock market. The fund uses the S&P Total Market Index (S&P Index) as its benchmark index to represent the U.S. stock market as a whole. Because the largest stocks in the index carry the most weight, large-capitalization stocks make up a substantial majority of the S&P Total Market Index’s value.

The fund attempts to match the performance of the S&P Index by using a sampling strategy, which involves investing substantially all of its assets in a broad spectrum of small-, mid-, and large-capitalization stocks representative of the S&P Index. The S&P Index includes approximately 3,700 stocks.

In an attempt to track the S&P Index, we select stocks based on industry, size, and other characteristics. For example, if technology stocks made up 15% of the S&P Index, the fund would invest about 15% of its assets in technology stocks with similar characteristics. Several factors are considered in selecting representative stocks, including historical price movement, market capitalization, transaction costs, and others.

Under normal conditions, the fund will invest at least 80% of its net assets (including any borrowings for investment purposes) in stocks that are held in its benchmark index. T. Rowe Price compares the composition of the fund to that of the index. If a material misweighting develops, the portfolio managers seek to rebalance the portfolio in an effort to realign it with its index.

While most assets will be invested in common stocks, the fund may also purchase stock index futures contracts. Futures would typically be used to reduce cash balances in the fund and increase the level of fund assets exposed to common stocks represented in the fund’s benchmark index.

While there is no guarantee, the correlation between the fund and its index is expected to be at least 0.95. A correlation of 1.00 indicates that the returns of the fund and the index will always move in the same direction (but not necessarily by the same amount). A correlation of 0.00 would mean movements in the fund are unrelated to movements in the index.

The fund may sell securities to better align its portfolio with the characteristics of its benchmark or to satisfy redemption requests. However, the fund is not required to sell specific securities that have been removed from its index.

Principal Risks As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund are summarized as follows:

Summary 3

Risks of stock investing Stocks generally fluctuate in value more than bonds and may decline significantly over short time periods. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising prices and falling prices. The value of a stock in which the fund invests may decline due to general weakness in the stock market or because of factors that affect a company or a particular industry.

Index investing risk Because the fund is passively managed and seeks to match the performance of its benchmark index, holdings are generally not reallocated based on changes in market conditions or outlook for a specific security, industry, or market sector. As a result, the fund’s performance may lag the performance of actively managed funds.

Tracking error The returns of the fund are expected to be slightly below the returns of its benchmark index (referred to as “tracking error”) because the fund incurs fees and transaction expenses while the index has no fees or expenses. Increased tracking error could also result from changes in the composition of the index or the timing of purchases and redemptions of fund shares. The fund uses a sampling strategy and does not attempt to fully replicate its benchmark index, which increases the potential for the fund’s performance to deviate from that of its index.

Futures risk To the extent the fund uses futures, it is exposed to potential volatility and losses greater than direct investments in the contract’s underlying assets.

Performance The bar chart showing calendar year returns and the average annual total returns table indicate risk by illustrating how much returns can differ from one year to the next and how fund performance compares with that of a comparable market index. The fund’s past performance (before and after taxes) is not necessarily an indication of future performance.

The fund can also experience short-term performance swings, as shown by the best and worst calendar quarter returns during the years depicted.

In addition, the average annual total returns table shows hypothetical after-tax returns to suggest how taxes paid by a shareholder may influence returns. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements, such as a 401(k) account or individual retirement account.
