Manager’s Letter

Fellow Shareholders

Major U.S. stock markets produced stellar returns, as they continued to climb through the second half of the year. The S&P 500 Index closed the year with its strongest annual gain since 1997. Although corporate fundamentals moderated from a strong level, investors remained optimistic about the economy. For the year ended December 31, 2013, the Equity Index 500, Total Equity Market Index, and Extended Equity Market Index Funds each posted gains of over 30%, broadly tracking the returns of their respective benchmarks.

MARKET ENVIRONMENT

U.S. equities produced excellent returns for the year ended December 31, 2013, in an environment characterized by steady labor market gains, favorable but moderating corporate earnings, and supportive monetary policies from the Fed. Each of the major stock indexes closed the year at record or multiyear highs. Investors remained optimistic despite rising longer-term interest rates stemming from expectations that the Fed would taper its $85 billion in monthly asset purchases in the near future, tensions in the Middle East, and a lack of cooperation among lawmakers regarding fiscal policy. The U.S. economy grew at a moderate pace, overcoming the higher tax rates and federal spending reductions that took effect in the first quarter of 2013, as well as the government shutdown and debt ceiling showdown in October. In mid-December, stock markets reacted favorably as the Fed decided to slowly taper its asset purchases, starting with a $10 billion reduction in January, and keep short-term interest rates low even if unemployment falls below 6.5%—as long as inflation remains contained. Finally, Congress announced a bipartisan two-year budget deal that temporarily suspends the fiscal brinkmanship of recent years.

As measured by various Russell indexes, growth stocks outperformed value stocks across all market capitalizations, especially among small-caps, which outperformed mid- and large-caps for the year. The large-cap S&P 500 Index gained 32.39% for the year, while the S&P Completion Index—a broad measure of small- and mid-cap stock performance—added 38.24%. All sectors within the S&P 500 gained over the reporting period. The consumer discretionary, health care, and industrials and business services sectors performed best, with gains over 40%. The utilities and telecommunication services sectors lagged, with moderate gains in the low teens.

SUMMARY OF INVESTMENT STRATEGIES

T. Rowe Price’s Equity Market Index Funds are designed for investors who want to harness the potential for long-term capital appreciation from broad exposure to large-cap stocks (Equity Index 500 Fund), small- and mid-cap stocks (Extended Equity Market Index Fund), or the entire U.S. stock market (Total Equity Market Index Fund). These funds could serve as core holdings in an investor’s portfolio, as they offer attributes that many investors will find appealing.

• They are well diversified, which can reduce the potentially negative impact of a given stock on the entire portfolio. The Equity Index 500 Fund invests in all S&P 500 Index stocks, while the Total Equity Market Index Fund and the Extended Equity Market Index Fund invested in 1,429 and 1,696 stocks, respectively, as of December 31, 2013. (Diversification cannot assure a profit or protect against loss in a declining market.)
   
• They tend to closely track their benchmarks. The Equity Index 500 Fund uses a full-replication strategy so that the weightings of our holdings match those of the S&P 500 Index. The Total Equity Market Index Fund and the Extended Equity Market Index Fund use a sampling strategy to approximate the sector allocations, price-to-earnings ratio, and other attributes of their benchmarks. We occasionally invest in securities such as futures and exchange-traded funds so that the index funds can accommodate cash flows and remain fully invested.
   
• They offer instant, broad exposure to different sectors of the stock market, and each fund’s sector allocations are consistent with its benchmark’s sector breakdown. As such, changes in the funds’ sector diversification and other overall characteristics reflect changes in the composition of the indexes, rather than strategic shifts that are typical of an actively managed fund. Since the funds are designed to track their respective indexes, they do not have the flexibility to shift assets toward stocks or sectors that are rising or away from those that are declining.
   
• Their expenses are generally low, which allows investors to retain more of their returns.

Equity Index 500 Fund
Your fund returned 32.02% in the 12 months ended December 31, 2013, versus 32.39% for the S&P 500 Index. Fund performance tends to slightly lag that of the benchmark due to operating and management expenses.

Every sector in the S&P 500 rose over the reporting period. Consumer discretionary, health care, and industrials and business services stocks were the top-performing sectors, with gains exceeding 40%, followed by financial stocks. Information technology, consumer staples, materials, and energy produced good returns as well. Telecommunication services and utilities gained the least, in the low double digits. Growth stocks outperformed value stocks in the S&P 500.

The consumer discretionary sector was the fund’s best performer, led by Netflix , the leading subscription streaming entertainment company; electronics retailer Best Buy , which seemed to benefit from a strategy change during the year; and GameStop , seller of new and used video games and hardware. Pharmaceutical company Celgene was the strongest performer in the health care sector on the success of its cancer-fighting drugs, while Boston Scientific and Gilead Sciences also performed well. In the industrials and business services sector, Boeing , the world’s leading aerospace company, ranked among the stronger performers. (Please refer to our portfolio of investments for a complete list of holdings and the amount each represents in the portfolio.)

Telecommunication services and utilities fared poorly last year. These generally defensive sectors—which pay the highest dividend yields in the S&P 500—fared well in recent years until early 2013, as investors sought defensive stocks with solid dividends in a low interest rate environment. But they suffered in the spring as yields surged after the Fed telegraphed its intention to start tapering its stimulus, leading investors to sell high-yielding stocks in favor of greater returns in the bond market.

Standard & Poor’s authorized 19 changes to the composition of the S&P 500 Index during the period. Please see the table on page 13 for a complete list of index changes.

Total Equity Market Index Fund
Your fund returned 33.70% for the 12 months ended December 31, 2013, versus 33.40% for its benchmark, the S&P Total Market Index. Fund performance often slightly trails that of the benchmark due to operating and management expenses; however, the fund’s sample of stocks outperformed the index for the year.

The S&P Total Market Index represents the entire U.S. stock market. It combines the S&P 500 and the S&P Completion Index and offers broad exposure to large-, mid-, small-, and micro-cap companies. Stocks in the S&P 500 represent over 75% of the S&P Total Market Index’s overall market value. As with the S&P 500, the largest holdings of the S&P Total Market Index have the greatest influence on the fund’s performance. In addition, the percentage weightings of the major sectors are broadly similar between the two benchmarks.

As with the S&P 500 Index, all sectors generated positive results. Consumer discretionary, health care, and industrials and business services stocks were the top-performing sectors, with gains exceeding 40%. Financials, information technology, consumer staples, energy, and materials all produced above-average returns. Telecommunication services and utilities lagged but still posted modest double-digit gains.

Extended Equity Market Index Fund
Your fund returned 38.37% for the 12 months ended December 31, 2013, versus 38.24% for the S&P Completion Index. Fund performance tends to slightly lag that of the benchmark due to the fund’s operating and management expenses; however, the fund’s sample of stocks outperformed the index for the year.

The S&P Completion Index, a subindex of the S&P Total Market Index, excludes all S&P 500 stocks. The index covers about 3,300 companies and provides exposure to mid-, small-, and micro-cap companies.

Every sector returned more than 23% for the period. Health care was the best-performing sector, with a gain of over 50%. Telecommunication services, consumer discretionary, industrials and business services, and consumer staples stocks each delivered gains of about 46% to 47%. Information technology also produced very good returns, as did energy stocks. Financials, materials, and utilities posted returns in the low- to mid-20% range.

OUTLOOK

Our growth expectations for the coming quarters remain modest. The U.S. economy is gradually recovering, supported by job gains, the housing rebound, and subdued energy prices. Fiscal headwinds, in the form of tax increases and spending cuts last year, are abating. Although the Fed pledged to keep interest rates low, there will likely be upward pressure on rates as the Fed reduces the amount of its asset purchases. U.S. corporate balance sheets and profit margins remain healthy. Earnings and revenue growth in the low- to mid-single-digit percentages are consistent with modest economic growth. Equity valuations are reasonable relative to historical levels based on several measures.

While we expect central bank monetary policies to remain accommodative for some time, uncertainty about the impact of the Fed’s tapering may periodically elevate market volatility. However, we remain focused on our role of replicating the structure and performance of the S&P indexes to provide our investors with broad exposure to large-cap stocks, small- and mid-cap stocks, and the entire U.S. stock market.

Thank you for investing with T. Rowe Price.

RISKS OF INVESTING

As with all stock mutual funds, the fund’s share price can fall because of weakness in the stock market, a particular industry, or specific holdings. Stock markets can decline for many reasons, including adverse political or economic developments, changes in investor psychology, or heavy institutional selling. The prospects for an industry or company may deteriorate because of a variety of factors, including disappointing earnings or changes in the competitive environment.

GLOSSARY

Price-to-cash flow ratio: A valuation measure calculated by dividing the price of a stock by its current cash flow per share. This ratio gives investors an idea of the market’s expectation of a firm’s future financial health by removing the effects of depreciation and other noncash factors.

Price-to-earnings (P/E) ratio: A valuation measure calculated by dividing the price of a stock by its reported earnings per share. The ratio is a measure of how much investors are willing to pay for the company’s earnings.

S&P 500 Index: An unmanaged index that tracks the stocks of 500 primarily large-cap U.S. companies.

S&P Completion Index: Tracks the performance of the U.S. stocks not included in the S&P 500, which are primarily small- and mid-capitalization stocks. The index includes approximately 3,300 stocks.

S&P Total Market Index: Tracks the performance of a broad spectrum of small-, mid-, and large-capitalization U.S. stocks. 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 index includes approximately 3,800 stocks.

Performance and Expenses

Growth of $10,000

This chart shows the value of a hypothetical $10,000 investment in the fund over the past 10 fiscal year periods or since inception (for funds lacking 10-year records). The result is compared with benchmarks, which may include a broad-based market index and a peer group average or index. Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.

Market indexes do not include expenses, which are deducted from fund returns as well as mutual fund averages and indexes.

Fund Expense Example

As a mutual fund shareholder, you may incur two types of costs: (1) transaction costs, such as redemption fees or sales loads, and (2) ongoing costs, including management fees, distribution and service (12b-1) fees, and other fund expenses. The following example is intended to help you understand your ongoing costs (in dollars) of investing in the fund and to compare these costs with the ongoing costs of investing in other mutual funds. The example is based on an investment of $1,000 invested at the beginning of the most recent six-month period and held for the entire period.

Actual Expenses
The first line of the following table (Actual) provides information about actual account values and actual expenses. You may use the information on this line, together with your account balance, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number on the first line under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes
The information on the second line of the table (Hypothetical) is based on hypothetical account values and expenses derived from the fund’s actual expense ratio and an assumed 5% per year rate of return before expenses (not the fund’s actual return). You may compare the ongoing costs of investing in the fund with other funds by contrasting this 5% hypothetical example and the 5% hypothetical examples that appear in the shareholder reports of the other funds. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period.

Note: T. Rowe Price charges an account service fee that is not included in the accompanying table. The account service fee is charged on a quarterly basis, usually during the last week of a calendar quarter, and applies to accounts with balances below $10,000 on the day of the assessment. The fee is charged to accounts that fall below $10,000 for any reason, including market fluctuations, redemptions, or exchanges. When an account with less than $10,000 is closed either through redemption or exchange, the fee is charged and deducted from the proceeds. The fee applies to IRAs but not to retirement plans directly registered with T. Rowe Price Services or accounts maintained by intermediaries through NSCC ^® Networking. If you are subject to the fee, keep it in mind when you are estimating the ongoing expenses of investing in the fund and when comparing the expenses of this fund with other funds.

You should also be aware that the expenses shown in the table highlight only your ongoing costs and do not reflect any transaction costs, such as redemption fees or sales loads. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds. To the extent a fund charges transaction costs, however, the total cost of owning that fund is higher.

Notes to Financial Statements

T. Rowe Price Index Trust, Inc. (the corporation), is registered under the Investment Company Act of 1940 (the 1940 Act). The Extended Equity Market Index Fund (the fund) is a diversified, open-end management investment company established by the corporation. The fund commenced operations on January 30, 1998. The fund seeks to track the performance of a benchmark index that measures the investment return of small- and mid-capitalization in U.S. stocks.

NOTE 1 - SIGNIFICANT ACCOUNTING P OLICIES

Basis of P reparation The fund is an investment company and follows accounting and reporting guidance in the Financial Accounting Standards Board Accounting Standards Codification Topic 946 (ASC 946). The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), including but not limited to ASC 946. GAAP requires the use of estimates made by management. Management believes that estimates and valuations are appropriate; however, actual results may differ from those estimates, and the valuations reflected in the accompanying financial statements may differ from the value ultimately realized upon sale or maturity.

Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Premiums and discounts on debt securities are amortized for financial reporting purposes. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions are reflected as realized gain/loss. Earnings on investments recognized as partnerships for federal income tax purposes reflect the tax character of such earnings. Dividend income and capital gain distributions are recorded on the ex-dividend date. Income tax-related interest and penalties, if incurred, would be recorded as income tax expense. Investment transactions are accounted for on the trade date. Realized gains and losses are reported on the identified cost basis. Distributions to shareholders are recorded on the ex-dividend date. Income distributions are declared and paid annually. Capital gain distributions, if any, are generally declared and paid by the fund annually.

Rebates Subject to best execution, the fund may direct certain security trades to brokers who have agreed to rebate a portion of the related brokerage commission to the fund in cash. Commission rebates are reflected as realized gain on securities in the accompanying financial statements.

Credits Credits are earned on the fund’s temporarily uninvested cash balances held at the custodian, and such credits reduce the amount paid by the manager for custody of the fund’s assets. In order to pass the benefit of custody credits to the fund, the manager has voluntarily reduced its investment management and administrative expense in the accompanying financial statements.

Redemption Fees A 0.5% fee is assessed on redemptions of fund shares held for 90 days or less to deter short-term trading and to protect the interests of long-term shareholders. Redemption fees are withheld from proceeds that shareholders receive from the sale or exchange of fund shares. The fees are paid to the fund and are recorded as an increase to paid-in capital. The fees may cause the redemption price per share to differ from the net asset value per share.

New Accounting Guidance On January 1, 2013, the fund adopted new accounting guidance, issued by the Financial Accounting Standards Board, that requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. Adoption had no effect on the fund’s net assets or results of operations.

NOTE 2 - VALUATION

The fund’s financial instruments are valued, and its net asset value (NAV) per share is computed at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day the NYSE is open for business.

Fair Value The fund’s financial instruments are reported at fair value, which GAAP defines as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The T. Rowe Price Valuation Committee (the Valuation Committee) has been established by the fund’s Board of Directors (the Board) to ensure that financial instruments are appropriately priced at fair value in accordance with GAAP and the 1940 Act. Subject to oversight by the Board, the Valuation Committee develops and oversees pricing-related policies and procedures and approves all fair value determinations. Specifically, the Valuation Committee establishes procedures to value securities; determines pricing techniques, sources, and persons eligible to effect fair value pricing actions; oversees the selection, services, and performance of pricing vendors; oversees valuation-related business continuity practices; and provides guidance on internal controls and valuation-related matters. The Valuation Committee reports to the fund’s Board; is chaired by the fund’s treasurer; and has representation from legal, portfolio management and trading, operations, and risk management.

Various valuation techniques and inputs are used to determine the fair value of financial instruments. GAAP establishes the following fair value hierarchy that categorizes the inputs used to measure fair value:

Level 1 – quoted prices (unadjusted) in active markets for identical financial instruments that the fund can access at the reporting date

Level 2 – inputs other than Level 1 quoted prices that are observable, either directly or indirectly (including, but not limited to, quoted prices for similar financial instruments in active markets, quoted prices for identical or similar financial instruments in inactive markets, interest rates and yield curves, implied volatilities, and credit spreads)

Level 3 – unobservable inputs

Observable inputs are developed using market data, such as publicly available information about actual events or transactions, and reflect the assumptions that market participants would use to price the financial instrument. Unobservable inputs are those for which market data are not available and are developed using the best information available about the assumptions that market participants would use to price the financial instrument. GAAP requires valuation techniques to maximize the use of relevant observable inputs and minimize the use of unobservable inputs. When multiple inputs are used to derive fair value, the financial instrument is assigned to the level within the fair value hierarchy based on the lowest-level input that is significant to the fair value of the financial instrument. Input levels are not necessarily an indication of the risk or liquidity associated with financial instruments at that level but rather the degree of judgment used in determining those values.

Valuation Tec h niques Equity securities listed or regularly traded on a securities exchange or in the over-the-counter (OTC) market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made. OTC Bulletin Board securities are valued at the mean of the closing bid and asked prices. A security that is listed or traded on more than one exchange is valued at the quotation on the exchange determined to be the primary market for such security. Listed securities not traded on a particular day are valued at the mean of the closing bid and asked prices. Actively traded domestic equity securities generally are categorized in Level 1 of the fair value hierarchy. OTC Bulletin Board securities and equity securities traded in inactive markets generally are categorized in Level 2 of the fair value hierarchy.

Debt securities generally are traded in the OTC market. Debt securities with remaining maturities of less than one year at the time of acquisition generally use amortized cost in local currency to approximate fair value. However, if amortized cost is deemed not to reflect fair value or the fund holds a significant amount of such securities with remaining maturities of more than 60 days, the securities are valued at prices furnished by dealers who make markets in such securities or by an independent pricing service. Generally, debt securities are categorized in Level 2 of the fair value hierarchy; however, to the extent the valuations include significant unobservable inputs, the securities would be categorized in Level 3.

Investments in mutual funds are valued at the mutual fund’s closing NAV per share on the day of valuation and are categorized in Level 1 of the fair value hierarchy. Financial futures contracts are valued at closing settlement prices and are categorized in Level 1 of the fair value hierarchy. Assets and liabilities other than financial instruments, including short-term receivables and payables, are carried at cost, or estimated realizable value, if less, which approximates fair value.

Thinly traded financial instruments and those for which the above valuation procedures are inappropriate or are deemed not to reflect fair value are stated at fair value as determined in good faith by the Valuation Committee. The objective of any fair value pricing determination is to arrive at a price that could reasonably be expected from a current sale. Financial instruments fair valued by the Valuation Committee are primarily private placements, restricted securities, warrants, rights, and other securities that are not publicly traded.

Subject to oversight by the Board, the Valuation Committee regularly makes good faith judgments to establish and adjust the fair valuations of certain securities as events occur and circumstances warrant. For instance, in determining the fair value of an equity investment with limited market activity, such as a private placement or a thinly traded public company stock, the Valuation Committee considers a variety of factors, which may include, but are not limited to, the issuer’s business prospects, its financial standing and performance, recent investment transactions in the issuer, new rounds of financing, negotiated transactions of significant size between other investors in the company, relevant market valuations of peer companies, strategic events affecting the company, market liquidity for the issuer, and general economic conditions and events. In consultation with the investment and pricing teams, the Valuation Committee will determine an appropriate valuation technique based on available information, which may include both observable and unobservable inputs. The Valuation Committee typically will afford greatest weight to actual prices in arm’s length transactions, to the extent they represent orderly transactions between market participants; transaction information can be reliably obtained; and prices are deemed representative of fair value. However, the Valuation Committee may also consider other valuation methods such as market-based valuation multiples; a discount or premium from market value of a similar, freely traded security of the same issuer; or some combination. Fair value determinations are reviewed on a regular basis and updated as information becomes available, including actual purchase and sale transactions of the issue. Because any fair value determination involves a significant amount of judgment, there is a degree of subjectivity inherent in such pricing decisions, and fair value prices determined by the Valuation Committee could differ from those of other market participants. Depending on the relative significance of unobservable inputs, including the valuation technique(s) used, fair valued securities may be categorized in Level 2 or 3 of the fair value hierarchy.

Valuation Inputs The following table summarizes the fund’s financial instruments, based on the inputs used to determine their fair values on December 31, 2013:

There were no material transfers between Levels 1 and 2 during the year.

Following is a reconciliation of the fund’s Level 3 holdings for the year ended December 31, 2013. Gain (loss) reflects both realized and change in unrealized gain/loss on Level 3 holdings during the period, if any, and is included on the accompanying Statement of Operations. The change in unrealized gain/loss on Level 3 instruments held at December 31, 2013, totaled $(7,000) for the year ended December 31, 2013. Transfers into and out of Level 3 are reflected at the value of the financial instrument at the beginning of the period. During the year, transfers into Level 3 resulted from a lack of observable market data for the security.

NOTE 3 - DERIVATIVE INSTRUMENTS

During the year ended December 31, 2013, the fund invested in derivative instruments. As defined by GAAP, a derivative is a financial instrument whose value is derived from an underlying security price, foreign exchange rate, interest rate, index of prices or rates, or other variable; it requires little or no initial investment and permits or requires net settlement. The fund invests in derivatives only if the expected risks and rewards are consistent with its investment objectives, policies, and overall risk profile, as described in its prospectus and Statement of Additional Information. The fund may use derivatives for a variety of purposes, such as seeking to hedge against declines in principal value, increase yield, invest in an asset with greater efficiency and at a lower cost than is possible through direct investment, or to adjust credit exposure. The risks associated with the use of derivatives are different from, and potentially much greater than, the risks associated with investing directly in the instruments on which the derivatives are based. The fund at all times maintains sufficient cash reserves, liquid assets, or other SEC-permitted asset types to cover its settlement obligations under open derivative contracts.

The fund values its derivatives at fair value, as described in Note 2, and recognizes changes in fair value currently in its results of operations. Accordingly, the fund does not follow hedge accounting, even for derivatives employed as economic hedges. Generally, the fund accounts for its derivatives on a gross basis. It does not offset the fair value of derivative liabilities against the fair value of derivative assets on its financial statements, nor does it offset the fair value of derivative instruments against the right to reclaim or obligation to return collateral. As of December 31, 2013, the fund held equity futures with cumulative unrealized gain of $1,453,000 and cumulative unrealized loss of $0; the value reflected on the accompanying Statement of Assets and Liabilities is the related unsettled variation margin.

Additionally, during the year ended December 31, 2013, the fund recognized $7,766,000 of realized gain on Futures and a $1,097,000 change in unrealized gain/ loss on Futures related to its investments in equity derivatives; such amounts are included on the accompanying Statement of Operations.

Counterparty Risk and Collateral The fund invests in exchange-traded or centrally cleared derivative contracts, such as futures, exchange-traded options, and centrally cleared swaps. Counterparty risk on such derivatives is minimal because the clearinghouse provides protection against counterparty defaults. For futures and centrally cleared swaps, the fund is required to deposit collateral in an amount equal to a certain percentage of the contract value (margin requirement), and the margin requirement must be maintained over the life of the contract. Each clearing broker, in its sole discretion, may adjust the margin requirements applicable to the fund.

Collateral may be in the form of cash or debt securities issued by the U.S. government or related agencies. Cash and currencies posted by the fund are reflected as cash deposits in the accompanying financial statements and generally are restricted from withdrawal by the fund; securities posted by the fund are so noted in the accompanying Portfolio of Investments; both remain in the fund’s assets. As of December 31, 2013, securities valued at $1,665,000 had been posted by the fund for exchange-traded and/or centrally cleared derivatives.

Futures Contracts The fund is subject to equity price risk in the normal course of pursuing its investment objectives and uses futures contracts to help manage such risk. The fund may enter into futures contracts as an efficient means of maintaining liquidity while being invested in the market, to facilitate trading, or to reduce transaction costs. A futures contract provides for the future sale by one party and purchase by another of a specified amount of a particular underlying financial instrument at an agreed-upon price, date, time, and place. The fund currently invests only in exchange-traded futures, which generally are standardized as to maturity date, underlying financial instrument, and other contract terms. Payments are made or received by the fund each day to settle daily fluctuations in the value of the contract (variation margin), which reflect changes in the value of the underlying financial instrument. Variation margin is recorded as unrealized gain or loss until the contract is closed. The value of a futures contract included in net assets is the amount of unsettled variation margin; net variation margin receivable is reflected as an asset and net variation margin payable is reflected as a liability on the accompanying Statement of Assets and Liabilities. Risks related to the use of futures contracts include possible illiquidity of the futures markets, contract prices that can be highly volatile and imperfectly correlated to movements in hedged security values, and potential losses in excess of the fund’s initial investment. During the year ended December 31, 2013, the fund’s exposure to futures, based on underlying notional amounts, was generally less than 1% of net assets.

NOTE 4 - OTHER INVESTMENT TRANSACTIONS

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks and/or to enhance performance. The investment objective, policies, program, and risk factors of the fund are described more fully in the fund’s prospectus and Statement of Additional Information.

Securities Lending The fund lends its securities to approved brokers to earn additional income. Its securities lending activities are administered by a lending agent in accordance with a securities lending agreement. It receives collateral in the form of cash or U.S. government securities, valued at 102% to 105% of the value of the securities on loan. Collateral is maintained over the life of the loan in an amount not less than the value of loaned securities; any additional collateral required due to changes in security values is delivered to the fund the next business day. Cash collateral is invested by the lending agent(s) in accordance with investment guidelines approved by fund management. Additionally, the lending agent indemnifies the fund against losses resulting from borrower default. Although risk is mitigated by the collateral and indemnification, the fund could experience a delay in recovering its securities and a possible loss of income or value if the borrower fails to return the securities, collateral investments decline in value and the lending agent fails to perform. Securities lending revenue consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower, compensation to the lending agent, and other administrative costs. In accordance with GAAP, investments made with cash collateral are reflected in the accompanying financial statements, but collateral received in the form of securities is not. At December 31, 2013, the value of loaned securities was $53,724,000, including securities sold but not yet settled, which are not reflected in the accompanying Portfolio of Investments; the value of cash collateral and related investments was $55,684,000.

Ot h er Purchases and sales of portfolio securities other than short-term securities aggregated $216,523,000 and $116,399,000, respectively, for the year ended December 31, 2013.

NOTE 5 - FEDERAL INCOME TA X ES

No provision for federal income taxes is required since the fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders all of its taxable income and gains. Distributions determined in accordance with federal income tax regulations may differ in amount or character from net investment income and realized gains for financial reporting purposes. Financial reporting records are adjusted for permanent book/tax differences to reflect tax character but are not adjusted for temporary differences.

The fund files U.S. federal, state, and local tax returns as required. The fund’s tax returns are subject to examination by the relevant tax authorities until expiration of the applicable statute of limitations, which is generally three years after the filing of the tax return but which can be extended to six years in certain circumstances. Tax returns for open years have incorporated no uncertain tax positions that require a provision for income taxes.

Reclassifications to paid-in capital relate primarily to a tax practice that treats a portion of the proceeds from each redemption of capital shares as a distribution of taxable net investment income or realized capital gain. For the year ended December 31, 2013, the following reclassifications were recorded to reflect tax character (there was no impact on results of operations or net assets):

Distributions during the years ended December 31, 2013 and December 31, 2012, were characterized for tax purposes as follows:

At December 31, 2013, the tax-basis cost of investments and components of net assets were as follows:

The difference between book-basis and tax-basis net unrealized appreciation (depreciation) is attributable to the deferral of losses from wash sales and the realization of gains/losses on certain open derivative contracts, for tax purposes.

NOTE 6 - RELATED P ARTY TRANSACTIONS

The fund is managed by T. Rowe Price Associates, Inc. (Price Associates), a wholly owned subsidiary of T. Rowe Price Group, Inc. (Price Group). The investment management and administrative agreement between the fund and Price Associates provides for an all-inclusive annual fee equal to 0.40% of the fund’s average daily net assets. The fee is computed daily and paid monthly. The all-inclusive fee covers investment management, shareholder servicing, transfer agency, accounting, and custody services provided to the fund, as well as fund directors’ fees and expenses. Interest, taxes, brokerage commissions, and extraordinary expenses are paid directly by the fund.

Additionally, the fund is one of several mutual funds in which certain college savings plans managed by Price Associates may invest. As approved by the fund’s Board of Directors, shareholder servicing costs associated with each college savings plan are allocated to the fund in proportion to the average daily value of its shares owned by the college savings plan. Shareholder servicing costs allocated to the fund are borne by Price Associates, pursuant to the fund’s all-inclusive fee agreement. At December 31, 2013, approximately 1% of the outstanding shares of the fund were held by college savings plans.

The fund may invest in the T. Rowe Price Reserve Investment Fund, the T. Rowe Price Government Reserve Investment Fund, or the T. Rowe Price Short-Term Reserve Fund (collectively, the Price Reserve Investment Funds), open-end management investment companies managed by Price Associates and considered affiliates of the fund. The Price Reserve Investment Funds are offered as short-term investment options to mutual funds, trusts, and other accounts managed by Price Associates or its affiliates and are not available for direct purchase by members of the public. The Price Reserve Investment Funds pay no investment management fees.

Report of Independent Registered Public Accounting Firm

To t h e Board of Directors of T. Rowe P rice Index Trust, Inc. and
S h are h olders of T. Rowe P rice Extended Equity Market Index Fund

In our opinion, the accompanying statement of assets and liabilities, including the portfolio of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of T. Rowe Price Extended Equity Market Index Fund (one of the portfolios comprising T. Rowe Price Index Trust, Inc., hereafter referred to as the “Fund”) at December 31, 2013, and the results of its operations, the changes in its net assets and the financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Fund’s management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2013 by correspondence with the custodian and brokers, and confirmation of the underlying funds by correspondence with the transfer agent, provide a reasonable basis for our opinion.

Item 2. Code of Ethics.

The registrant has adopted a code of ethics, as defined in Item 2 of Form N-CSR, applicable to its principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of this code of ethics is filed as an exhibit to this Form N-CSR. No substantive amendments were approved or waivers were granted to this code of ethics during the period covered by this report.

Item 3. Audit Committee Financial Expert.

The registrant’s Board of Directors/Trustees has determined that Mr. Anthony W. Deering qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. Deering is considered independent for purposes of Item 3 of Form N-CSR.

Item 4. Principal Accountant Fees and Services.

(a) – (d) Aggregate fees billed for the last two fiscal years for professional services rendered to, or on behalf of, the registrant by the registrant’s principal accountant were as follows:

Audit fees include amounts related to the audit of the registrant’s annual financial statements and services normally provided by the accountant in connection with statutory and regulatory filings. Audit-related fees include amounts reasonably related to the performance of the audit of the registrant’s financial statements and specifically include the issuance of a report on internal controls and, if applicable, agreed-upon procedures related to fund acquisitions. Tax fees include amounts related to services for tax compliance, tax planning, and tax advice. The nature of these services specifically includes the review of distribution calculations and the preparation of Federal, state, and excise tax returns. All other fees include the registrant’s pro-rata share of amounts for agreed-upon procedures in conjunction with service contract approvals by the registrant’s Board of Directors/Trustees.

(e)(1) The registrant’s audit committee has adopted a policy whereby audit and non-audit services performed by the registrant’s principal accountant for the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant require pre-approval in advance at regularly scheduled audit committee meetings. If such a service is required between regularly scheduled audit committee meetings, pre-approval may be authorized by one audit committee member with ratification at the next scheduled audit committee meeting. Waiver of pre-approval for audit or non-audit services requiring fees of a de minimis amount is not permitted.

     (2) No services included in (b) – (d) above were approved pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X.

(f) Less than 50 percent of the hours expended on the principal accountant’s engagement to audit the registrant’s financial statements for the most recent fiscal year were attributed to work performed by persons other than the principal accountant’s full-time, permanent employees.

(g) The aggregate fees billed for the most recent fiscal year and the preceding fiscal year by the registrant’s principal accountant for non-audit services rendered to the registrant, its investment adviser, and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant were $1,691,000 and $1,802,000, respectively.

(h) All non-audit services rendered in (g) above were pre-approved by the registrant’s audit committee. Accordingly, these services were considered by the registrant’s audit committee in maintaining the principal accountant’s independence.
