What is each fund`s objective?

Equity Index 500 Fund seeks to match the performance of the Standard & Poor`s 500 Stock Index®. The S&P 500 is made up of primarily large-capitalization companies that represent a broad spectrum of the U.S. economy and a substantial part of the U.S. stock market`s total capitalization. (Market capitalization is the number of a company`s outstanding shares multiplied by the market price per share.)

Extended Equity Market Index Fund seeks to match the performance of the U.S. stocks not included in the S&P 500, which are primarily small and mid capitalization stocks. We use the S&P Completion Index to represent this universe.

Total Equity Market Index Fund seeks to match the performance of the entire U.S. stock market. We use the S&P Total Market Index to represent the 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`s value.

<R>
International Equity Index Fund seeks to provide long-term capital growth. We use the FTSExaa International Limited ("FTSE") Developed ex North America Index, an equity market index based on the market capitalization of over 1,200 predominately large companies listed in Japan, the U.K., and developed countries in Continental Europe and the Pacific Rim.
</R>

U.S. Bond Index Fund seeks to match the total return performance of the U.S. investment-grade bond market. We use the Lehman Brothers U.S. Aggregate Index, which typically includes more than 6,000 fixed-income securities with an overall intermediate to long average maturity. The maturity range was 6.15 to 7.66 years for the last five years ended December 31, 2007, although it will vary with market conditions.

The inclusion of a stock or bond in the S&P, FTSExaa , or the Lehman Brothers indices is not an endorsement by Standard & Poor`s, FTSExaa , or Lehman Brothers of the stock or bond as an investment, nor are S&P, FTSExaa , and Lehman Brothers sponsors of the funds or in any way affiliated with them.

What is each fund`s principal investment strategy?

Equity Index 500 Fund invests substantially all of its assets in all of the stocks in the S&P 500 Index. We attempt to maintain holdings of each stock in proportion to its weight in the index. This is known as a full replication strategy.

Standard & Poor`s constructs the index by first identifying major industry categories and then allocating a representative sample of the larger and more liquid stocks in those industries to the index. S&P weights each stock according to its total market value. For example, the 50 largest companies in the index may account for over 50% of its value.

Extended Equity Market Index Fund uses a sampling strategy, investing substantially all of its assets in a group of stocks representative of the S&P Completion Index. The fund does not attempt to fully replicate the index by owning each of the stocks in it. The index includes approximately 4,000 stocks.

Total Equity Market Index Fund also uses a sampling strategy, investing substantially all of its assets in a broad spectrum of small-, mid-, and large-capitalization stocks representative of the S&P Total Market Index. The index includes approximately 4,500 stocks.

In an attempt to recreate each of the S&P indices, we select stocks in terms of industry, size, and other characteristics. For example, if technology stocks made up 15% of the S&P Completion Index, the Extended Equity Market Index 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.

International Equity Index Fund seeks to match the performance of the FTSExaa Developed ex North America Index by using a full replication strategy. This involves investing substantially all of its assets in all of the stocks in the index in proportion to each stock`s weight in the index. The index is constructed by selecting the countries it covers, sorting the market by industry groups, and
targeting a significant portion of them for inclusion in the index.

Fund Profile

<R>
U.S. Bond Index Fund uses a sampling strategy, investing substantially all fund assets in bonds specifically represented in the Lehman Brothers U.S. Aggregate Index. Prior to July 1, 2008, the fund`s strategy is to match the performance of the index gross of fund expenses. Effective July 1, 2008, the fund`s strategy will be to match the performance of the index net of fund expenses. Gross performance reflects the return of the fund`s investments without consideration of the fund`s expenses, whereas net performance reflects the return of the fund`s investments after all of the fund`s expenses have been deducted. This change in strategy means the fund will attempt to offset the expenses that it incurs (as of the date of this prospectus, the fund`s annual expense ratio is 0.30%) and have its total return match the total return of the index. Within each broad segment of the index, such as government bonds, mortgages, and corporate issues, we will select a set of U.S. dollar-denominated bonds that represents key benchmark traits. The most important of these traits are interest rate sensitivity, credit quality, and sector diversification, although other characteristics will be reflected. One or more of these traits will normally be given a slightly greater or lesser emphasis than its representation in the index once the fund begins efforts to match the performance of the index net of fund expenses. The fund`s holdings will normally include U.S. government and agency obligations, mortgage- and asset-backed securities, corporate bonds, and U.S. dollar-denominated securities of foreign issuers. Municipal bonds may also be included in the fund.
</R>

All funds

<R>
T. Rowe Price compares the composition of the stock index funds to that of the indices. If a misweighting develops, the portfolios are rebalanced in an effort to bring them into line with their respective indices. In addition to stocks, the stock funds may purchase exchange-traded funds, stock index futures, or stock options in an effort to minimize any deviations in performance with their indices.
</R>

<R>
In addition to its normal investments, the bond index fund may purchase collateralized mortgage obligations (CMOs) and certain types of derivatives, provided they have similar characteristics to index securities but potentially offer more attractive prices, yields, or liquidity. Derivatives, such as futures, options, and swaps, will not exceed 10% of the fund`s total assets.

Fund Profile

While there is no guarantee, the investment manager expects the correlation between each fund and its index to be at least 0.95. A correlation of 1.00 would mean the returns of the fund and the index almost 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.

Each fund may sell securities to better align its portfolio with the characteristics of its benchmark or satisfy redemption requests. However, the funds are not required to sell specific issues that have been removed from their indices.

Certain investment restrictions, such as a required minimum or maximum investment in a particular type of security, are measured at the time each fund purchases a security. The status, market value, maturity, credit quality, or other characteristics of each fund`s securities may change after they are purchased, and this may cause the amount of each fund`s assets invested in such securities to exceed the stated maximum restriction or fall below the stated minimum restriction. If any of these changes occur, it would not be considered a violation of the investment restriction. However, purchases by a fund during the time it is above or below the stated percentage restriction would be made in compliance with applicable restrictions.

Further information about each fund`s investments, including a review of market conditions and fund strategies and their impact on performance, is available in the annual and semiannual shareholder reports.

What are the main risks of investing in the funds?

All funds except U.S. Bond Index Fund

The funds are designed to track broad segments of the U.S. and foreign stock marketswhether they are rising or falling. Markets as a whole can decline for many reasons, including adverse political or economic developments here or abroad, changes in investor psychology, or heavy institutional selling.

Since each fund is passively managed and seeks to remain fully invested at all times, assets cannot be shifted from one stock or group of stocks to another based on their prospects, or from stocks into bonds or cash equivalents in an attempt to cushion the impact of a market decline. Therefore, actively managed funds may outperform these funds.

Equity Index 500 Fund While there is no guarantee, this fund should tend to be less volatile than the other three stock portfolios because of its focus on U.S. larger-cap stocks. The fund emphasizes large-cap stocks, which may at times lag shares of smaller, faster-growing companies. It may also pay a modest dividend that can help offset losses in falling markets.

Fund Profile

Extended Equity Market Index Fund  This fund will be subject to the greater risks associated with small- and mid-cap stocks. Smaller companies often have limited product lines, markets, or financial resources, and may depend on a small group of inexperienced managers. The securities of small companies may have limited marketability and liquidity and are often subject to more abrupt or erratic market movements than shares of larger companies or the major market averages. The very nature of investing in smaller companies involves greater risk than is customarily associated with large-cap companies.

Total Equity Market Index Fund  While there is no guarantee, this fund is expected to have a risk level between the other two U.S. funds, and should have higher dividends than the Extended Equity Market Index Fund.

International Equity Index Fund  .Funds that invest overseas generally carry more risk than funds that invest strictly in U.S. assets. Even investments in countries with highly developed economies are subject to significant risks. Some particular risks affecting this fund include the following:

  • Currency risk  This refers to a decline in the value of a foreign currency versus the U.S. dollar, which reduces the dollar value of securities denominated in that currency. The overall impact on a fund`s holdings can be significant, unpredictable, and long-lasting, depending on the currencies represented in the portfolio and how each one appreciates or depreciates in relation to the U.S. dollar. Under normal conditions, the fund does not expect to hedge its currency exposure.
  • Other risks of foreign investing  Risks can result from varying stages of economic and political development, differing regulatory environments, trading days, and accounting standards, uncertain tax laws, and higher transaction costs of non-U.S. markets. Investments outside the United States could be subject to governmental actions such as capital or currency controls, nationalization of a company or industry, expropriation of assets, or imposition of high taxes.
  • While certain countries have made progress in economic growth, liberalization, fiscal discipline, and political and social stability, there is no assurance these trends will continue.

    Tracking error  While all of the index funds are susceptible to some degree of tracking error, the use of sampling for the Extended Equity Market Index and Total Equity Market Index Funds, in particular, will likely result in increased deviation from their respective indices. In addition, for all four index funds, returns are likely to be slightly below those of the indices because the funds have fees and transaction expenses while indices have none. The timing of cash flows and a fund`s size can also influence returns. For example, a fund`s failure to reach a certain asset size may limit its ability to purchase all the stocks in the index and achieve full replication. Or, a large cash flow into or out of a fund may cause its return to deviate from the index.

    Fund Profile

    Futures/options risk  To the extent the funds use futures and options, they are exposed to additional volatility and potential losses.

    U.S. Bond Index Fund

    <R>
    This fund is designed to track the performance of investment-grade bonds, regardless of whether they are rising or falling. (Effective July 1, 2008, the fund will be managed to track the performance of the Lehman Brothers U.S. Aggregate Index net of fund expenses.) As a result, the fund will not be able to avoid declining bond markets and actively managed funds may outperform it. Index funds carry the same overall risks as the indices they are designed to track. The following are the principal risks of the fund:
    </R>

  • Interest rate risk  Investors should be concerned primarily with this risk because the Lehman Brothers U.S. Aggregate Index has typically had an intermediate to long weighted average maturity. An increase in interest rates will likely cause the fund`s share price to fall, resulting in a loss of principal. Prices fall because the bonds and fixed-income securities in the fund`s portfolio become less attractive to other investors when securities with higher yields become available. Even GNMAs and other securities whose principal and interest payments are guaranteed can decline in price if rates rise. Generally speaking, the longer a bond`s maturity, the greater its potential for price declines if rates rise and for price gains if rates fall. Therefore, this fund carries more interest rate risk than short-term bond funds.
  • Credit risk  This risk is the chance that any of the fund's holdings will have their credit ratings downgraded or will default (fail to make scheduled interest or principal payments), potentially reducing the fund`s income level and share price.
  • Most investment-grade (AAA through BBB) securities should have relatively low financial risk and a relatively high probability of future payment. However, securities rated BBB are more susceptible to adverse economic conditions and may have speculative characteristics. If the fund invests in securities whose issuers develop unexpected credit problems, the fund`s price could decline.

    The fund may continue to hold a security that has been downgraded or loses its investment-grade rating after purchase.

    <R>
  • Prepayment risk and extension risk  A fund investing in mortgage-backed bonds can be hurt when interest rates fall because homeowners tend to refinance and prepay principal. Receiving increasing prepayments in a falling interest rate environment causes the average maturity of the portfolio to shorten, reducing its potential for price gains. It also requires the fund to reinvest proceeds at lower interest rates, which reduces the portfolio`s total return and yield, and could result in a loss if bond prices fall below the level the fund paid for them.

  • these developments could result in a decrease in the fund`s income, share price, or total return.
  • </R>

    <R>
    Extension risk refers to a rise in interest rates or lack of refinancing opportunities that can cause a fund`s average maturity to lengthen unexpectedly due to a drop in prepayments. This would increase the fund`s sensitivity to rising rates and its potential for price declines.
    </R>

    <R>
  • Liquidity risk This is the chance that the fund may not be able to sell securities at desired prices. Sectors of the bond market can experience sudden downturns in trading activity. During periods of reduced trading, the spread can widen between the price at which a security can be bought and the price at which it can be sold. Less liquid securities can become more difficult to value and be subject to erratic price movements.
  • </R>

  • Derivatives risk  Shareholders are also exposed to derivatives risk, the potential that the fund`s investments (if any) in these complex and volatile instruments could affect the fund`s share price. In addition to CMOs and better-known instruments such as swaps and futures, other derivatives that may be used in limited fashion by the fund include interest-only (IO) and principal-only (PO) securities known as "strips." Some of these instruments can be highly volatile, and their value can fall dramatically in response to rapid or unexpected changes in the mortgage, interest rate, or economic environment.
  • <R>
  • Tracking error  Differences between the composition of the fund and its index, as well as differences in pricing sources, could result in tracking error, or the risk that fund performance will not match that of the index. Tracking error can also result because the fund incurs fees and transaction expenses while indices have none. The timing of cash flows and the fund`s size can also influence returns. Finally, the fund`s efforts to match the performance of its index net of fund expenses could be unsuccessful, increasing the fund`s tracking error.

    All funds

    As with any mutual fund, there can be no guarantee the funds will achieve their objectives.

    <R>
    Each fund`s share price may decline, so when you sell your shares, you may lose money. An investment in the funds is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

    How can I tell which fund is most appropriate for me?

    Consider your investment goals, your time horizon for achieving them, and your tolerance for risk. The segments of the market to which you want exposure and the degree of volatility you can accept in pursuit of income or long-term capital gains can guide you in choosing among the funds.

    Fund Profile

    If you seek a relatively lowcost way of participating in the U.S. equity markets through a passively managed portfolio, the Equity Index 500, Extended Equity Market Index, or Total Equity Market Index Fund could be an appropriate part of your overall investment strategy.

    The S&P 500 Index is one of the most widely tracked stock indices in the world. If you want to closely match the performance of the mostly largecap stocks in this index, with the same level of risk, the Equity Index 500 Fund may be an appropriate choice.

    If you seek potentially higher returns, can assume greater risk, and want broad exposure to small and midcap stocks, you may wish to invest in the Extended Equity Market Index Fund.

    If your risk profile is between that of the Equity Index 500 Fund and the Extended Equity Market Index Fund, and you would like to participate in the entire U.S. stock market, you may want to consider the Total Equity Market Index Fund.

    If you want to diversify your domestic stock portfolio by adding exposure to an index of developed international stock markets and can accept the risks that accompany foreign investments, the International Equity Index Fund could be an appropriate part of your overall investment strategy.

    Equity investors should have a long-term investment horizon and be willing to wait out bear markets.

    If you seek a low-cost way to participate in the U.S. investment-grade bond market through a fund that tracks a well-known benchmark, the U.S. Bond Index Fund may be an appropriate investment.

    The fund or funds you select should not represent your complete investment program or be used for short-term trading purposes.

    Each fund can be used in both regular and tax-deferred accounts, such as IRAs.

    How has each fund performed in the past?

    The bar charts 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. Past fund returns (before and after taxes) are not necessarily an indication of future performance.

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

    Fund Profile

    In addition, the average annual total returns table shows hypothetical after-tax returns to suggest how taxes paid by the shareholder may influence returns. Actual after-tax returns depend on each investor`s situation and may differ from those shown. After-tax returns are not relevant if the shares are held in a tax-deferred account, such as a 401(k) or IRA. During periods of fund losses, the post-liquidation after-tax return may exceed the fund`s other returns because the loss generates a tax benefit that is factored into the result.

    Fund Profile

    Returns are based on changes in principal value, reinvested dividends, and capital gain distributions, if any. Returns before taxes do not reflect effects of any income or capital gains taxes. Taxes are computed using the highest federal income tax rate. The after-tax returns reflect the rates applicable to ordinary and qualified dividends and capital gains effective in 2003. The returns do not reflect the impact of state and local taxes. Returns after taxes on distributions reflect the taxed return on the payment of dividends and capital gains. Returns after taxes on distributions and sale of fund shares assume the shares were sold at period-end and, therefore, are also adjusted for any capital gains or losses incurred by the shareholder. Market indexes do not include expenses, which are deducted from fund returns, or taxes.

    What fees and expenses will I pay?

    The shares that are offered in this prospectus are 100% no load. However, the funds charge a redemption fee, payable to the funds, on shares purchased and held 90 days or less. The fee is 2.00% for International Equity Index Fund and 0.50% for the other funds. The purpose of the fee is to discourage short-term trading, which increases transaction costs for the funds.

    The Extended Equity Market Index, Total Equity Market Index, International Equity Index, and U.S. Bond Index Funds each have a single fee covering investment management and ordinary recurring operating expenses. In contrast, most mutual funds have a fixed management fee plus a fee for operating expenses.

    There are no other fees or charges to buy or sell fund shares, reinvest dividends, or exchange into other T. Rowe Price funds. There are no 12b1 fees.

However, no reimbursement will be made after April 30, 2010, or three years after the waiver or payment, whichever is sooner, or if it would result in the expense ratio exceeding 0.35%. Any amounts reimbursed will have the effect of increasing fees otherwise paid by the fund. The fund operated under a previous expense limitation for which T. Rowe Price may be reimbursed.

    dThe management fee includes operating expenses.

    <R>
    eThe fund indirectly bears its share of the expenses paid by acquired funds in which it invests; such indirect expenses are not paid from the fund`s assets but are reflected in the return realized by the fund on its investment in the acquired funds.

    Example.  The following table gives you an idea of how expense ratios may translate into dollars and helps you to compare the cost of investing in these funds with that of other mutual funds. Although your actual costs may be higher or lower, the table shows how much you would pay if operating expenses remain the same, the expense limitation currently in place is not renewed (if applicable), you invest $10,000, earn a 5% annual return, hold the investment for the following periods, and then redeem:
