Fellow Shareholders

International stocks continued to set a robust pace during the past six months, delivering substantial returns for the 6- and 12-month periods ended October 31, 2005. European stocks did well in both periods, and Japan’s results were outstanding during the past six months. Other markets in which the fund invests, including Singapore and Hong Kong, posted moderate returns.

The fund returned 8.06% over the six months ended October 31, 2005, versus 8.82% for its benchmark index. Fund results relative to the benchmark primarily reflect the fund’s operating and management expenses, as well as taxes. The fund seeks to match the performance of the FTSE Developed ex North America Index, a broadly diversified stock market index based on the investable market capitalization of more than 1,000 predominantly larger companies listed in 21 countries (the index’s performance reflects no operational costs, management fees, or taxes). The index’s major markets include the U.K., Japan, and developed countries in Europe and the Pacific Rim. It is constructed by sorting the market in each country in the index by industry groups and targeting a significant portion of the stocks in these groups for inclusion. The fund attempts to replicate the index by investing in the stocks included in the index in proportion to their weighting.

At the end of October, Europe represented 67.2% of net assets, with Japan and the Pacific Rim representing most of the balance. The U.K. was the largest country allocation followed closely by Japan (see the Geographic Diversification table elsewhere in this report for a breakdown of regional allocations). Financial stocks were the largest sector weighting at 28.7% of assets, followed by consumer discretionary stocks (11.1%), industrials and business services (9.3%), energy (8.2%), consumer staples (7.5%), health care (7.4%), materials (7.0%), telecommunication services (6.7%), utilities (5.0%), information technology (4.9%), and trusts (4.1%).

THE DOLLAR RISES AGAIN 

The U.S. dollar gained 12% against the yen, 8% in relation to the British pound, and 12% versus the euro this year, through October 31. The dollar’s strength was largely due to rising yields relative to Europe and Japan, the faster pace of U.S. economic growth than in other major developed markets, and strong demand from overseas investors.

Why should you care about the U.S. greenback’s strength or weakness versus other currencies? If you have been a tourist in a foreign country, you know that a strong dollar allows you to buy more goods and services per dollar. (For example, if you can buy a euro for $1.10 rather than $1.20 —the exchange rate on October 31, 2005—you spend fewer dollars for a cab ride, dinner, and a bottle of wine.) Along the same lines, a strong dollar makes imported goods and services less expensive for U.S. purchasers. Even if the currency price charged by the foreign exporter does not change, the strong dollar means it costs fewer dollars to buy the product. Conversely, a weak dollar makes U.S. goods more attractive in overseas markets.

Investing in foreign stocks and bonds involves the same type of currency translations. Initially, dollars must be converted into the local currency to buy the securities. Subsequently, price quotations, dividends and interest payments, and redemptions must be translated back into U.S. dollars. Because foreign exchange rates continually change due to each currency’s supply and demand, currency movements can increase or decrease the dollar value of an investment even if the security’s price remains unchanged. U.S. investors benefited from the falling green-back in 2004. The MSCI EAFE (Europe, Australasia, and Far East) Index gained 13.1% in local-currency terms but, thanks to currency exchange, produced a 20.7% return for U.S. investors.

With several more Fed rate hikes in prospect and solid fundamental underpinnings—corporate earnings gains at the fore—T. Rowe Price International portfolio managers believe the U.S. dollar has reasonable support at current levels versus other currencies. Over the longer term, however, our managers believe these positive factors will moderate and the dollar will reverse course due to concerns about the ballooning U.S. trade and budget deficits and the likelihood of rate hikes by the European Central Bank.

MARKET REVIEW

After peaking 15 years ago, the Japanese stock market experienced a steady swoon until 2003 but now seems to have turned the corner. The resurgence in Japanese equities has boosted share prices to levels not seen since 2001. After a few false starts, the world’s second-largest economy appears to be getting back on track. Recent growth has been driven by consumer and corporate spending rather than just exports, and Japan is exhibiting signs of a self-sustaining recovery. In addition, the country benefited from a decisive election, which returned the reform-minded Prime Minister Junichiro Koizumi to office and raised hopes of even more radical reforms, which may be seen as a tailwind for further economic growth.

While tailwinds drove Japan, the headwinds of rising inflation, slowing employment growth, and moderating real estate values plagued developed Europe and hurt consumer spending. The terror attacks in London over the summer, along with a sharp slowdown in consumer spending, hindered economic growth in the U.K. Indeed, GDP growth there plunged to a 12-year low in the second quarter and prompted the Bank of England to cut interest rates. In addition, continuing high unemployment in France and Germany remains an issue. The German elections ended with neither major party securing a commanding majority. Angela Merkel, the leader of the Christian Democrats, will replace Social Democrat Gerhard Schroeder as chancellor, but she will be heading a coalition government, which will make reforms harder to implement. Notwithstanding the mixed political message, the major European bourses managed to hit a three-year high during the past six months as high levels of liquidity and appealing share price valuations fueled merger and acquisition activity.

Developed Asia outside Japan is still closely linked to China, with a large number of Chinese stocks listed in Singapore and Hong Kong to attract international investors. China’s economy grew strongly, but the growth failed to trickle down to the micro level where companies are still blighted by weak corporate governance.

PORTFOLIO HIGHLIGHTS

Overall, the materials sector did extremely well during the past 6- and 12-month periods as high raw material prices were driven by demand in Asia. Japanese steel and financial companies, including banking and financial services giant Mitsubishi Tokyo Financial, posted good results. As expected, rising oil prices fueled advances in the energy sector. Major integrated energy company BP and oil and gas exploration company Royal Dutch Shell, both of the U.K., were the two top holdings in the portfolio. (Please refer to our detailed list of holdings and the amount each represents of the portfolio.)

Industrial shares also delivered good results over both periods, and Japan’s Toyota Motor benefited from the economic recovery now under way in that country. Telecom was among the lagging sectors due largely to greater competition and pricing pressures in Europe, and weak investments in information technology because of fears of accelerating inflation and tepid global demand. In developed regions, Japan returned the most over the past six months, while the Pacific ex-Japan also prospered thanks to the area’s shipping and building ties to China, as well as strength in natural resources and banks.

Other key holdings included Royal Bank of Scotland, which turned in less than stellar results because of weak credit, retail, and GDP growth; the bank remains exposed to a slowdown in the U.K. economy. Switzerland’s Novartis was held back by speculation that the company was planning to acquire another pharmaceutical company, but management has since made it clear that such a deal is not on the agenda in the near term. U.K. pharmaceutical AstraZeneca advanced sharply during the past six months, while the outlook for France’s Sanofi-Aventis is tied to the launch of a new drug in the first half of 2006. The company is defending challenges to several patents, which are unlikely to be resolved before the end of 2006.

Again, we would like to remind shareholders that it is not the fund’s purpose to attempt to outperform its benchmark, but rather to match its performance by buying stocks held in the index. We should also call shareholders’ attention to the four series of iShares listed among the portfolio’s 25 largest holdings. These shares help us manage cash flows as we strive to achieve the fund’s performance objective by replicating the stocks, sectors, countries, and regions represented in the index along with their respective weightings.

INVESTMENT OUTLOOK

Higher energy prices have not yet impaired global economic growth. Corporate profitability is generally robust, and we expect companies to continue generating positive earnings growth, albeit at a slower rate. The main concerns in the near term are possible slowdowns in Chinese growth and U.S. consumption, which would restrain international economies overall. At the end of October, growth stocks had finally begun to overtake value shares after a long stretch of relative weakness. In addition, inflationary trends could put further upward pressure on interest rates, which would also serve to slow global growth as European rates narrow the gap with their U.S. counterparts.

Increasingly, investors have begun to focus on structural reforms in Europe, particularly in Germany, which could enable Europe to preserve its global competitiveness if such reforms should come about. Attractive relative stock valuations continue to underpin European equities markets, and cash generation is at a 30-year high. In Japan, economic growth has continued its upward trend, and earnings quality has improved as companies boost revenues and cut costs. The corporate sector enjoys high liquidity, reflecting declining debt repayments, and dividend payments are expected to increase.

For investors looking to invest in foreign equities markets, the diversification provided in an index fund portfolio of international stocks offers a prudent, low-cost alternative to actively managed funds.

Respectfully submitted,

E. Frederick Bair
President and chairman of the fund’s Investment Advisory Committee

November 18, 2005

The committee chairman has day-to-day responsibility for managing the portfolio and works with committee members in developing and executing the fund’s investment program.

CHANGE IN MANAGEMENT

On May 1, 2005, E. Frederick Bair replaced Richard T. Whitney as chairman of the fund’s Investment Advisory Committee. Mr. Bair joined T. Rowe Price in 1998 and has been managing investments since 2000. He is a vice president of T. Rowe Price Associates, Inc., and also serves as a vice president and advisory committee member of the Diversified Small-Cap Growth Fund and Balanced Fund. Prior to joining T. Rowe Price, Mr. Bair was an equity trader at Legg Mason. He earned a B.S. in Accounting from Pennsylvania State University and is both a chartered financial analyst and a certified public accountant.

RISKS OF INTERNATIONAL INVESTING

Funds that invest overseas generally carry more risk than funds that invest strictly in U.S. assets. Funds investing in a single country or in a limited geographic region tend to be riskier than more diversified funds. Risks can result from varying stages of economic and political development; differing regulatory environments, trading days, and accounting standards; and higher transaction costs of non-U.S. markets. Non-U.S. investments are also subject to currency risk, or 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.

GLOSSARY

FTSE Developed ex North America Index: A broadly diversified stock market index based on the investable market capitalization of more than 1,000 predominantly larger companies listed in 21 countries. The index’s major markets include the U.K., Japan, and developed countries in Europe and the Pacific Rim.

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.

AVERAGE ANNUAL COMPOUND TOTAL RETURN 

This table shows how the fund would have performed each year if its actual (or cumulative) returns for the periods shown had been earned at a constant rate.

FUND EXPENSE EXAMPLE 

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 in 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 in 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 maintenance fee that is not included in the accompanying table. The account maintenance 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 IRA accounts 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 

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

T. Rowe Price International Index Fund, Inc. (the corporation) is registered under the Investment Company Act of 1940 (the 1940 Act). The International Equity Index Fund (the fund), a diversified, open-end management investment company, is one portfolio established by the corporation. The fund commenced operations on November 30, 2000. The fund seeks to provide long-term capital growth, using the FTSE™ International Limited Developed ex North America Index.

The accompanying financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, which require the use of estimates made by fund management. Fund management believes that estimates and security valuations are appropriate; however actual results may differ from those estimates, and the security valuations reflected in the financial statements may differ from the value the fund ultimately realizes upon sale of the securities.

Valuation The fund values its investments and computes its net asset value per share at the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day that the NYSE is open for business. Equity securities listed or regularly traded on a securities exchange or in the over-the-counter market are valued at the last quoted sale price or, for certain markets, the official closing price at the time the valuations are made, except for OTC Bulletin Board securities, which are valued at the mean of the latest 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 latest bid and asked prices for domestic securities and the last quoted sale price for international securities.

Investments in mutual funds are valued at the mutual fund’s closing net asset value per share on the day of valuation.

Other investments, including restricted securities, 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 T. Rowe Price Valuation Committee, established by the fund’s Board of Directors.

Most foreign markets close before the close of trading on the NYSE. If the fund determines that developments between the close of a foreign market and the close of the NYSE will, in its judgment, materially affect the value of some or all of its portfolio securities, which in turn will affect the fund’s share price, the fund will adjust the previous closing prices to reflect the fair value of the securities as of the close of the NYSE, as determined in good faith by the T. Rowe Price Valuation Committee, established by the fund’s Board of Directors. A fund may also fair value securities in other situations, such as when a particular foreign market is closed but the fund is open. In deciding whether to make fair value adjustments, the fund reviews a variety of factors, including developments in foreign markets, the performance of U.S. securities markets, and the performance of instruments trading in U. S. markets that represent foreign securities and baskets of foreign securities. The fund uses outside pricing services to provide it with closing market prices and information used for adjusting those prices. The fund cannot predict when and how often it will use closing prices and when it will adjust those prices to reflect fair value. As a means of evaluating its fair value process, the fund routinely compares closing market prices, the next day’s opening prices in the same markets, and adjusted prices.

Currency Translation Assets, including investments, and liabilities denominated in foreign currencies are translated into U.S. dollar values each day at the prevailing exchange rate, using the mean of the bid and asked prices of such currencies against U.S. dollars as quoted by a major bank. Purchases and sales of securities, income, and expenses are translated into U.S. dollars at the prevailing exchange rate on the date of the transaction. The effect of changes in foreign currency exchange rates on realized and unrealized security gains and losses is reflected as a component of security gains and losses.

Redemption Fees A 2% fee is assessed on redemptions of fund shares held less than 90 days/3 months to deter short-term trading and 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.

Investment Transactions, Investment Income, and Distributions Income and expenses are recorded on the accrual basis. Dividends received from mutual fund investments are reflected as dividend income; capital gain distributions are reflected as realized gain/loss. Dividend income and capital gain distributions are recorded on the ex-dividend date. 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 on an annual basis. Capital gain distributions, if any, are declared and paid by the fund, typically on an annual basis.

NOTE 2 - INVESTMENT TRANSACTIONS

Consistent with its investment objective, the fund engages in the following practices to manage exposure to certain risks or 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. It receives as collateral cash and U.S. government securities valued at 102% to 105% of the value of the securities on loan. Cash collateral is invested in a money market pooled account managed by the fund’s lending agent in accordance with investment guidelines approved by fund management. Collateral is maintained over the life of the loan in an amount not less than the value of loaned securities, as determined at the close of fund business each day; any additional collateral required due to changes in security values is delivered to the fund the next business day. Although risk is mitigated by the collateral, 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. Securities lending revenue recognized by the fund consists of earnings on invested collateral and borrowing fees, net of any rebates to the borrower and compensation to the lending agent. At October 31, 2005, the value of loaned securities was $13,134,000; aggregate collateral consisted of $13,669,000 in the money market pooled account.

Other Purchases and sales of portfolio securities, other than short-term securities, aggregated $126,370,000 and $48,271,000, respectively, for the year ended October 31, 2005.

NOTE 3 - FEDERAL INCOME TAXES

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. Federal income tax regulations differ from generally accepted accounting principles; therefore, distributions determined in accordance with tax regulations may differ significantly 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. Financial records are not adjusted for temporary differences.

Distributions during the year ended October 31, 2005 totaled $851,000 and were characterized as ordinary income for tax purposes. At October 31, 2005, the tax-basis components of net assets were as follows:

Federal income tax regulations require the fund to treat the gain/loss on passive foreign investment companies as realized on the last day of the tax year; accordingly, $301,000 of unrealized gains reflected in the accompanying financial statements were realized for tax purposes as of October 31, 2005. The fund intends to retain realized gains to the extent of available capital loss carryforwards for federal income tax purposes. During the fiscal year ended October 31, 2005, the fund utilized $591,000 of capital loss carryforwards, $186,000 of which were acquired in mergers. As of October 31, 2005, the fund had $900,000 of capital loss carryforwards that expire in fiscal 2010, and $1,454,000 that expire in fiscal 2011; substantially, all of the fund’s capital loss carryforwards at year end were acquired through mergers and are subject to certain limitations.

For the year ended October 31, 2005, the fund recorded the following permanent reclassifications to reflect tax character. 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 and/or realized capital gain. Results of operations and net assets were not affected by these reclassifications.

At October 31, 2005, the cost of investments for federal income tax purposes was $137,155,000.

NOTE 4 - FOREIGN TAXES

The fund is subject to foreign income taxes imposed by certain countries in which it invests. Foreign income taxes are accrued by the fund as a reduction of income.

NOTE 5 - ACQUISITION

On July 11, 2005, the T. Rowe Price International Equity Index Fund acquired substantially all of the assets of the TD Waterhouse Asian Pacific Index Fund and the TD Waterhouse European Index Fund (collectively, the acquired funds), pursuant to the Agreement and Plan of Reorganization dated March 23, 2005, and approved by shareholders of the acquired funds on June 28, 2005. The acquisition was accomplished by a tax-free exchange of 1,150,435 shares of the T. Rowe Price International Equity Index Fund (with a value of $12,045,000) for the 1,599,203 shares of the TD Waterhouse Asian Pacific Index Fund outstanding at the merger date; an additional 1,325,916 shares of the T. Rowe Price International Equity Index Fund (with a value of $13,882,000) were exchanged for the 1,526,191 shares of the TD Waterhouse European Index Fund outstanding on July 8, 2005. The aggregate net assets of the acquired funds at that date included $2,072,000 of unrealized appreciation, and $2,525,000 of realized losses carried forward for tax purposes to offset distributable gains realized in the future. Upon merger, the aggregate net assets of the acquired funds were combined with those of the T. Rowe Price International Equity Index Fund, immediately after which, the net assets of the T. Rowe Price International Equity Index Fund totaled $116,941,000.

NOTE 6 - RELATED PARTY TRANSACTIONS

The fund is managed by T. Rowe Price International, Inc. (the manager), a wholly owned subsidiary of T. Rowe Price Associates, Inc. (Price Associates), which is wholly owned by T. Rowe Price Group, Inc. The investment management and administrative agreement between the fund and the manager provides for an all-inclusive annual fee equal to 0.50% of the fund’s average daily net assets. The fee is computed daily and paid monthly. The agreement provides that investment management, shareholder servicing, transfer agency, accounting, and custody services are provided to the fund, and interest, taxes, brokerage commissions, directors’ fees and expenses, and extraordinary expenses are paid directly by the fund.

The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe Price Government Reserve Investment Fund (collectively, the T. Rowe Price Reserve Funds), open-end management investment companies managed by Price Associates and affiliates of the fund. The T. Rowe Price Reserve Funds are offered as cash management options to mutual funds, trusts, and other accounts managed by Price Associates and/or its affiliates, and are not available for direct purchase by members of the public. The T. Rowe Price Reserve Funds pay no investment management fees. During the year ended October 31, 2005, dividend income from the T. Rowe Price Reserve Funds totaled $11,000, and the value of shares of the T. Rowe Price Reserve Funds held at October 31, 2005 and October 31, 2004 was $257,000 and $1,288,000, respectively.

As of October 31, 2005, T. Rowe Price Group, Inc. and/or its wholly owned subsidiaries owned 319,726 shares of the fund, representing 2.6% of the fund’s net assets.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors of T. Rowe Price International Index Fund, Inc. and Shareholders of T. Rowe Price International Equity 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 International Equity Index Fund (the portfolio comprising T. Rowe Price International Index Fund, Inc., hereafter referred to as the “Fund”) at October 31, 2005, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the fiscal periods presented, 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 auditing 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 October 31, 2005 by correspondence with the custodian and by agreement to the underlying ownership records for T. Rowe Price Reserve Investment Fund, 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. Donald W. Dick Jr. qualifies as an audit committee financial expert, as defined in Item 3 of Form N-CSR. Mr. Dick is considered independent for purposes of Item 3 of Form N-CSR.

Item 4. Principal Accountant Fees and Services.

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

	2005	2004
Audit Fees	$10,939	$10,003
Audit-Related Fees	799	965
Tax Fees	2,747	2,753
All Other Fees	369	124

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, specifically the issuance of a report on internal controls. Tax fees include amounts related to tax compliance, tax planning, and tax advice. 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 $1,010,000 and $903,000, respectively, and were less than the aggregate fees billed for those same periods by the registrant’s principal accountant for audit services rendered to the T. Rowe Price Funds.

(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.

(b) The registrant’s principal executive officer and principal financial officer are aware of no change in the registrant’s internal control over financial reporting that occurred during the registrant’s second fiscal quarter covered by this report that has materially affected, or is reasonably likely to materially affect, the registrant’s internal control over financial reporting.
